Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Referring to fig. 1-7, a mixing conveyor 100 for dispensing a lotion according to an embodiment of the present invention will be described, wherein the mixing conveyor 100 can be used in a dispensing device of a washing machine for dispensing a lotion into a washing chamber of the washing machine.

As shown in fig. 1 to 7 (the direction of the arrows in fig. 5 and 7 is the flow direction of the fluid), the mixing conveyor 100 for dispensing the lotion according to the embodiment of the first aspect of the present invention includes: a mixing conveyor body 1 and a water passage 2.

The mixing conveyor body 1 is internally provided with a water flow channel 111, a mixing channel 121, a lotion channel 122 and a pressure relief channel 123, the mixing channel 121 is connected downstream of the water flow channel 111 in the water flow direction, the mixing channel 121 is communicated with the water flow channel 111, the lotion channel 122 is communicated with the mixing channel 121, lotion is suitable for flowing into the mixing channel 121 through the lotion channel 122, the water flow channel 111 is suitable for introducing water flow, the water flow flowing into the water flow channel 111 can flow into the mixing channel 121, the lotion flowing into the mixing channel 121 is mixed with the water flow, and finally the lotion flows into a washing cavity of the washing machine.

The water passage member 2 is movably disposed in the water flow passage 111, and the water passage member 2 can be pushed to move by the water inlet pressure, for example, the water passage member 2 is pushed to move along the axial direction of the water flow passage 111 by the water inlet pressure. The water passage member 2 may also be driven to move by a driving mechanism, for example, the water passage member 2 may be driven to move along the axial direction of the water flow passage 111 by the driving mechanism, or the water passage member 2 may be driven to rotate around its central axis by the driving mechanism.

The water flow is adapted to flow through the water passage member 2 to the mixing channel 121, for example the water passage member 2 may have an inlet 211 and an outlet 221, the water flow is adapted to enter the water passage member 2 from the inlet 211 and to flow out to the mixing channel 121 from the outlet 221, the outlet 221 may be adjacent to the mixing channel 121 or the outlet 221 may be located in the mixing channel 121. Because it sets up in rivers passageway 111 to lead to water spare 2, can be less with the flow area setting of leading to water spare 2, at rivers flow through the in-process of water spare 2, it can carry out the pressure boost acceleration rate to rivers to lead to water spare 2, rivers can spout to mixing channel 121 in with higher velocity of flow from the spout 221 that leads to water spare 2, the impact effect of reinforcing rivers, make water and lotion intensive mixing, the foaming, and then can improve the dissolution effect and the foaming effect of lotion, improve the washing effect.

Alternatively, the water passage member 2 may be formed in a tubular shape. This simplifies the structure of the water passage member 2.

The pressure relief passage 123 and the water flow passage 111 can be communicated and isolated by the movement of the water passing member 2. When the pressure relief channel 123 is communicated with the water flow channel 111, a part of the water flowing into the water flow channel 111 flows into the mixing channel 121 to be mixed with the lotion flowing into the mixing channel 121, and finally flows into the washing cavity of the washing machine; the other part flows into the pressure relief passage 123 and finally flows into the washing chamber of the washing machine. When the pressure release channel 123 is blocked from the water flow channel 111, the water flowing into the water flow channel 111 flows into the mixing channel 121, mixes with the lotion flowing into the mixing channel 121, and finally flows into the washing chamber of the washing machine.

For example, the water inlet pressure is used to push the water passage member 2 to move, for example, when the water inlet pressure is used to push the water passage member 2 to move along the axial direction of the water flow channel 111, when the water flow is not introduced into the water flow channel 111, the water passage member 2 is not acted by external force, and at this time, the pressure relief channel 123 and the water flow channel 111 can be separated; when rivers let in rivers passageway 111, it is under the pushing action of rivers to lead to water spare 2, it can make pressure release passageway 123 and rivers passageway 111 communicate to lead to water spare 2 activity, some rivers that flow into rivers passageway 111 at this moment flow into in mixing channel 121 and another part rivers flow into in pressure release passageway 123, make rivers can get into washing machine's washing intracavity simultaneously through two passageways, rivers that get into rivers passageway 111 respectively through mixing channel 121 and pressure release passageway 123 entering washing machine's washing intracavity simultaneously, from this when guaranteeing the lotion dissolving effect in mixing channel 121, can increase the discharge in the unit interval, thereby can improve washing machine's the efficiency of intaking. And because pressure release channel 123 shunts pressure release to rivers, when pressure of intaking was too big, pressure release channel 123 can play the effect of shunting pressure release, can reduce the pressure that the inlet tube bore to can reduce because the too big risk that causes washing machine's inlet tube to damage of water pressure.

Further, when the water passing member 2 is pushed to move by the water inlet pressure and water flows into the water flow channel 111, whether the pressure relief channel 123 and the water flow channel 111 are communicated or separated can be determined according to the water inlet pressure. For example, when the water inlet pressure is lower than the set pressure, although the water flow member 2 moves under the pushing of the water flow, the movement distance is small, so that the pressure relief passage 123 and the water flow passage 111 are separated, and the water flowing into the water flow passage 111 all flows into the mixing passage 121; when the water inlet pressure is not lower than the set pressure, the water passing piece 2 moves under the pushing of the water flow and the moving distance is larger, the water passing piece 2 moves to the position where the pressure relief channel 123 is communicated with the water flow channel 111, and the water flows into the water flow channel 111, wherein one part of the water flows into the mixing channel 121 and the other part of the water flows into the pressure relief channel 123.

For another example, when the driving mechanism is used to drive the water passing member 2 to move, the driving mechanism can determine whether to drive the water passing member 2 to move according to the detected water inlet pressure by detecting the water inlet pressure. When water flow is not introduced into the water flow channel 111, the detected water inlet pressure is zero, and the driving mechanism can drive the water passing piece 2 to move so that the water passing piece 2 moves to a position where the pressure relief channel 123 and the water flow channel 111 are separated. When water flow is introduced into the water flow channel 111, whether the driving mechanism is controlled to act is determined according to whether the detected water inlet pressure is lower than the set pressure. Specifically, when the detected water inlet pressure is lower than the set pressure, the driving mechanism can drive the water passing member 2 to move so that the water passing member 2 moves to a position where the pressure relief channel 123 and the water flow channel 111 are separated; when the water inlet pressure is not lower than the set pressure, the driving mechanism can drive the water passing piece 2 to move, so that the water passing piece 2 moves to a position where the pressure relief channel 123 is communicated with the water flow channel 111.

Therefore, in the water inlet process of the washing machine, after water flows enter the water flow channel 111, when the water inlet pressure is high, the pressure relief channel 123 and the water flow channel 111 can be communicated through the activity of the water passing piece 2, and the water flows can be divided, so that the water flows can enter the washing cavity of the washing machine through the two channels at the same time, namely, the water flows entering the water flow channel 111 respectively enter the washing cavity of the washing machine through the mixing channel 121 and the pressure relief channel 123 at the same time, therefore, the water inlet amount in unit time can be increased while the lotion dissolving effect in the mixing channel 121 is ensured, and the water inlet efficiency of the washing machine can be improved. And because pressure release channel 123 shunts rivers, when pressure of intaking is too big, pressure release channel 123 can play the effect of reposition of redundant personnel pressure release, can reduce the pressure that the inlet tube bore to can reduce because the too big risk that causes washing machine's inlet tube to damage of water pressure.

And, when pressure of intaking is less, can make pressure release channel 123 cut off with rivers passageway 111 through the activity of logical water spare 2 to can guarantee to get into the rivers pressure in mixing channel 121, thereby can guarantee the mixed effect of lotion and rivers in the mixing channel 121, make the lotion can be more abundant dissolve.

The lotion comprises detergent, softener, disinfectant and the like, namely the lotion generally refers to additives for putting in a laundry process. When the washing machine is in a washing stage, detergent can enter the mixing channel 121 through the washing channel 122 to be mixed with water flow entering the mixing channel 121, so that the washing agent can be dissolved in the water flow and finally flows into a washing cavity of the washing machine; when the washing machine is in the rinsing stage, the softener and the disinfectant can enter the mixing channel 121 through the washing channel 122 and are mixed with the water flow entering the mixing channel 121, so that the softener and the disinfectant can be dissolved in the water flow and finally flow into a washing cavity of the washing machine.

Alternatively, the mixing channel 121 may be configured as a venturi structure. Thereby, the venturi effect can be utilized, so that the water flow during its flow through the mixing channel 121 generates a negative pressure in its vicinity, with which the lotion can be sucked into the lotion channel 122 and into the mixing channel 121.

In other embodiments, lotion can also be pumped into the lotion channel 122 and into the mixing channel 121 by a pump.

When the mixing channel 121 is configured as a venturi structure, lotion can be pumped into the lotion channel 122 by a pump, and the venturi effect can serve as an auxiliary function to play a certain role in pumping lotion.

According to the mixing conveyor 100 for dispensing the lotion provided by the embodiment of the invention, when the mixing conveyor 100 is used for a dispensing device of a washing machine, the mixing conveyor 100 can mix the lotion and water and then dispense the mixture into a washing cavity of the washing machine, the pressure relief channel 123 is arranged on the mixing conveyor body 1, the movable water passing piece 2 is arranged in the water flow channel 111, the pressure relief channel 123 and the water flow channel 111 can be communicated and separated through the movement of the water passing piece 2, when the pressure relief channel 123 is communicated with the water flow channel 111, the water flow in the water flow channel 111 is subjected to shunting pressure relief through the pressure relief channel 123, when the water inlet pressure is too high, the pressure relief channel 123 can perform shunting pressure relief, and the risk of damage to a water inlet pipe of the washing machine due to too high water pressure can be reduced.

According to some embodiments of the present invention, referring to fig. 3, 5 and 7, the water passage member 2 is movably disposed in the water passage 111 along the axial direction of the water passage 111, and the pressure relief passage 123 and the water passage 111 can be connected and disconnected by moving the water passage member 2 along the axial direction of the water passage 111. This makes the movement of the water passage member 2 simple and easy to control.

According to some embodiments of the present invention, the water passage member 2 has an inlet 211 and an outlet 221, the water flow is adapted to enter the water passage member 2 from the inlet 211 and flow out to the mixing channel 121 from the outlet 221, the outlet 221 may be adjacent to the mixing channel 121 or the outlet 221 may be located within the mixing channel 121. Because it sets up in rivers passageway 111 to lead to water spare 2, can be less with the flow area setting of leading to water spare 2, at rivers flow through the in-process of water spare 2, it can carry out the pressure boost acceleration rate to rivers to lead to water spare 2, rivers can spout to mixing channel 121 in with higher velocity of flow from the spout 221 that leads to water spare 2, the impact effect of reinforcing rivers, make water and lotion intensive mixing, the foaming, and then can improve the dissolution effect and the foaming effect of lotion, improve the washing effect.

The pressure relief channel 123 can be communicated with and separated from the inner cavity of the water passing piece 2 through the movement of the water passing piece 2. When the pressure relief channel 123 is communicated with the inner cavity of the water passing piece 2, a part of water flowing into the water passing piece 2 flows into the mixing channel 121 to be mixed with the lotion flowing into the mixing channel 121, and finally flows into the washing cavity of the washing machine; the other part flows into the pressure relief passage 123 and finally flows into the washing chamber of the washing machine. When the pressure release channel 123 is blocked from the inner cavity of the water passing member 2, the water flowing into the water passing member 2 flows into the mixing channel 121, is mixed with the lotion flowing into the mixing channel 121, and finally flows into the washing cavity of the washing machine.

For example, the water inlet pressure is used to push the water passing member 2 to move, for example, when the water inlet pressure is used to push the water passing member 2 to move along the axial direction of the water flow channel 111, when the water flow is not introduced into the water flow channel 111, the water passing member 2 is not acted by external force, and at this time, the pressure relief channel 123 and the inner cavity of the water passing member 2 can be separated; when rivers let in rivers passageway 111 in, it can make pressure release passageway 123 and the inner chamber intercommunication of logical water spare 2 to lead to the activity of water spare 2 under the pushing action of rivers, it is partly in mixing channel 121 and another part rivers inflow pressure release passageway 123 that flow into in the rivers of logical water spare 2 this moment, make rivers can get into washing machine's washing intracavity simultaneously through two passageways, rivers that get into in rivers passageway 111 respectively get into washing machine's washing intracavity through mixing channel 121 and pressure release passageway 123 simultaneously, from this when guaranteeing the lotion dissolving effect in mixing channel 121, can increase the discharge in the unit interval, thereby can improve washing machine's water intake efficiency. And because pressure release channel 123 shunts pressure release to rivers, when pressure of intaking was too big, pressure release channel 123 can play the effect of shunting pressure release, can reduce the pressure that the inlet tube bore to can reduce because the too big risk that causes washing machine's inlet tube to damage of water pressure.

Further, when the water flow channel 111 is filled with water by pushing the water passing member 2 to move by using the water inlet pressure, whether the pressure relief channel 123 is communicated with the inner cavity of the water passing member 2 or is cut off can be determined according to the water inlet pressure. For example, when the water inlet pressure is lower than the set pressure, although the water passing member 2 moves under the pushing of the water flow, the moving distance is small, so that the pressure relief passage 123 and the inner cavity of the water passing member 2 are separated, and the water flow flowing into the water passing member 2 flows into the mixing passage 121; when the water inlet pressure is not lower than the set pressure, the water passing piece 2 moves under the pushing of water flow, the moving distance is large, the water passing piece 2 moves to a position where the pressure relief channel 123 is communicated with the inner cavity of the water passing piece 2, the water flows into the water passing piece 2, one part of the water flows into the mixing channel 121, and the other part of the water flows into the pressure relief channel 123.

For another example, when the driving mechanism is used to drive the water passing member 2 to move, the driving mechanism can determine whether to drive the water passing member 2 to move according to the detected water inlet pressure by detecting the water inlet pressure. When water flow is not introduced into the water flow channel 111, the detected water inlet pressure is zero, and the driving mechanism can drive the water passing piece 2 to move so that the water passing piece 2 moves to a position where the pressure relief channel 123 and the inner cavity of the water passing piece 2 are separated. When water flow is introduced into the water flow channel 111, whether the driving mechanism is controlled to act is determined according to whether the detected water inlet pressure is lower than the set pressure. Specifically, when the detected water inlet pressure is lower than the set pressure, the driving mechanism can drive the water passing piece 2 to move so that the water passing piece 2 moves to a position where the pressure relief channel 123 and the inner cavity of the water passing piece 2 are separated; when the water inlet pressure is not lower than the set pressure, the driving mechanism can drive the water passing piece 2 to move, so that the water passing piece 2 moves to a position where the pressure relief channel 123 is communicated with the inner cavity of the water passing piece 2.

Therefore, in the water inlet process of the washing machine, after water flows into the water flow channel 111 and flows into the water passing part 2, when the water inlet pressure is high, the pressure relief channel 123 is communicated with the inner cavity of the water passing part 2 through the activity of the water passing part 2, and the water flow can be divided, so that the water flow can simultaneously enter the washing cavity of the washing machine through the two channels, namely the water flow entering the water flow channel 111 simultaneously enters the washing cavity of the washing machine through the mixing channel 121 and the pressure relief channel 123 respectively, therefore, the water inlet amount in unit time can be increased while the lotion dissolving effect in the mixing channel 121 is ensured, and the water inlet efficiency of the washing machine can be improved. And because pressure release channel 123 shunts rivers, when pressure of intaking is too big, pressure release channel 123 can play the effect of reposition of redundant personnel pressure release, can reduce the pressure that the inlet tube bore to can reduce because the too big risk that causes washing machine's inlet tube to damage of water pressure.

And, when pressure of intaking is less, can make pressure release channel 123 cut off with the inner chamber of logical water spare 2 through the activity of logical water spare 2 to can guarantee to get into the rivers pressure in mixing channel 121, thereby can guarantee the mixed effect of lotion and rivers in the mixing channel 121, make the lotion can be comparatively abundant dissolve.

According to some alternative embodiments of the present invention, when no water flows into the water flow passage 111 (refer to fig. 3), the pressure relief passage 123 is isolated from the inner cavity of the water passing member 2; when water flow is introduced into the water flow channel 111 and the water inlet pressure is lower than the set pressure (refer to fig. 7), the pressure relief channel 123 is isolated from the inner cavity of the water passing piece 2, and at this time, the water flow entering the water passing piece 2 all flows into the mixing channel 121, so that the water flow pressure entering the mixing channel 121 can be ensured, the lotion entering the mixing channel 121 can be more fully dissolved, and at this time, the risk of damage to the water inlet pipe is very low because the water inlet pressure is low; when water flows into the water flow channel 111 and the water inlet pressure is not lower than the set pressure (refer to fig. 5), the pressure relief channel 123 is communicated with the inner cavity of the water passing member 2, and a part of the water flows into the mixing channel 121 and the other part of the water flows into the pressure relief channel 123, so that the risk of damage to the water inlet pipe of the washing machine due to excessive water pressure can be reduced, and the water inlet efficiency can be improved.

According to some alternative embodiments of the present invention, referring to fig. 3, 5 and 7, a first communication port 1111 communicating with the water flow channel 111 and the pressure release channel 123 is formed on a side wall of the water passage channel 111, a pressure release port 212 is formed on a side wall of the water passage member 2, the pressure release channel 123 communicates with the inner cavity of the water passage member 2 when at least a portion of the pressure release port 212 is opposite to the first communication port 1111, and the pressure release channel 123 communicates with the inner cavity of the water passage member 2 when the entire pressure release port 212 is opposite to the first communication port 1111. A part of the water flow in the water passage member 2 flows into the mixing passage 121, and the other part of the water flow in the water passage member 2 flows into the pressure release passage 123 through the pressure release port 212 and the first communication port 1111; when the pressure relief opening 212 and the first communication opening 1111 are staggered (the term "staggered pressure relief opening 212 and the first communication opening 1111" means that the pressure relief opening 212 and the entire first communication opening 1111 are completely staggered), the pressure relief opening 212 may be opposite to the side wall of the water flow channel 111, the side wall of the water flow channel 111 may close the pressure relief opening 212, the pressure relief channel 123 is blocked from the inner cavity of the water passage 2, and the water flow in the water passage 2 flows into the mixing channel 121. Therefore, through the arrangement, the communication and the separation of the pressure relief channel 123 and the inner cavity of the water passing piece 2 can be conveniently realized, and the structure is simple.

In some embodiments of the present invention, referring to fig. 3, 5 and 7, the water passage member 2 is movably provided in the water flow passage 111 in the axial direction of the water flow passage 111. When water is not introduced into the water flow passage 111, the pressure relief port 212 is located upstream of the first communication port 1111 in the water flow direction; the pressure relief port 212 is located upstream of the first communication port 1111 in the flow direction of the water flow when the water flow is introduced into the water flow passage 111 and the water inlet pressure is lower than the set pressure.

Thus, when water is not flowing through water flow channel 111, pressure relief port 212 is located upstream of first communication port 1111 in the direction of water flow, and pressure relief port 212 of water flow member 2 is offset from first communication port 1111 of water flow channel 111. When water flows into the water flow channel 111, the water flow entering the water flow channel 111 can be used for pushing the water flow member 2 to move towards the direction adjacent to the mixing channel 121, or the driving mechanism can be used for driving the water flow member 2 to move towards the direction adjacent to the mixing channel 121, when the water inlet pressure is lower than the set pressure, the distance that the water flow member 2 moves forwards (forwards refers to the direction adjacent to the mixing channel 121) is smaller, the pressure relief opening 212 is still located at the upstream of the first communication opening 1111 in the water flow direction, and at this time, the pressure relief opening 212 on the water flow member 2 is still staggered with the first communication opening 1111 on the water flow channel 111; when the pressure of intaking is not less than the settlement pressure, can utilize rivers to promote to lead to water piece 2 and can move great distance forward, also can utilize actuating mechanism drive to lead to water piece 2 and move great distance forward for at least partly first connection port 1111 on the pressure release mouth 212 on leading to water piece 2 is relative with rivers passageway 111, thereby can make partly rivers in leading to water piece 2 shunt to pressure release passageway 123, thereby play the effect of reposition of redundant personnel pressure release, reduce the inlet tube because the damage risk that intake pressure is too big to cause. And, when pressure of intaking is not less than the settlement pressure, the pressure of intaking is big more, and the area that can make pressure release mouth 212 and the relative part of first intercommunication portion 1111 through the pushing effect of rivers or through control actuating mechanism is big more to it is big more to shunt the discharge in to pressure release passageway 123, thereby can play better reposition of redundant personnel pressure release effect.

In some alternative embodiments of the present invention, referring to fig. 3, 5 and 7, the water passage member 2 is movably disposed in the water passage 111 in the axial direction of the water passage 111, the water passage member 2 is connected to the inner wall of the water passage 111 by the elastic member 3 or the water passage member 2 is connected to the inner wall of the mixing passage 121 by the elastic member 3, and the elastic member 3 is elastically deformable in the axial direction of the water passage 111, for example, the elastic member 3 may be a spring. When water is not introduced into the water flow passage 111, the pressure relief port 212 is located upstream of the first communication port 1111 in the water flow direction; the pressure relief port 212 is located upstream of the first communication port 1111 in the flow direction of the water flow when the water flow is introduced into the water flow passage 111 and the water inlet pressure is lower than the set pressure.

Thereby, the elastic connection between the water passage member 2 and the inner wall of the water flow passage 111 or the inner wall of the mixing passage 121 can be realized, and the water passage member 2 can be moved in the axial direction of the water flow passage 111 within a set range. When water is not introduced into the water flow channel 111, the pressure relief port 212 is located upstream of the first communication port 1111 in the water flow direction, and the pressure relief port 212 of the water passage member 2 is staggered from the first communication port 1111 of the water flow channel 111. When water flows into the water flow channel 111, the water flow entering the water flow channel 111 pushes the water flow member 2 to move towards the direction adjacent to the mixing channel 121, the water flow needs to overcome the elastic force of the elastic member 3, when the water inlet pressure is lower than the set pressure, the distance that the water flow member 2 moves forwards (forwards refers to the direction adjacent to the mixing channel 121) is smaller, the pressure relief opening 212 is still located at the upstream of the first communication opening 1111 in the water flow direction, and at this time, the pressure relief opening 212 on the water flow member 2 is still staggered with the first communication opening 1111 on the water flow channel 111; when the water inlet pressure is not lower than the set pressure, the water flow pushes the water passing part 2 to move forwards by a larger distance, at least one part of the pressure relief opening 212 on the water passing part 2 is opposite to the first communication opening 1111 on the water flow channel 111, so that one part of the water flow in the water passing part 2 can be distributed to the pressure relief channel 123, the effect of distributing and relieving the pressure is achieved, and the damage risk of the water inlet pipe caused by the overlarge water inlet pressure is reduced. And, when pressure of intaking was not less than the settlement pressure, the pressure of intaking was big more, and the area of pressure release 212 and the relative part of first intercommunication portion 1111 is big more to reposition of redundant personnel to the discharge in the pressure release passageway 123 is big more, thereby can play better reposition of redundant personnel pressure release effect.

Further, referring to fig. 3, 5 and 7, the elastic member 3 is located between the mixing channel 121 and the water passing member 2, one axial end of the elastic member 3 is connected to one end of the water passing member 2 adjacent to the mixing channel 121, a limit step portion 1212 is formed on an inner wall of the mixing channel 121, and the other axial end of the elastic member 3 is connected to the limit step portion 1212. From this, through this setting for the setting position of elastic component 3 is reasonable, and makes things convenient for rivers directly to promote the removal of logical water part 2, and sets up spacing ladder 1212 through the inner wall at mixing channel 121, makes things convenient for the installation of elastic component 3.

According to some embodiments of the invention, a gas flow channel 124 is formed in the mixing conveyor body 1 in communication with the mixing channel 121, through which gas (e.g. air) is adapted to flow into the mixing channel 121. In the process of using the mixing conveyor 100 to throw the lotion, water flows into the water flow channel 111 of the mixing conveyor 100 and flows into the mixing channel 121 through the water passing piece 2, the lotion flows into the mixing channel 121 through the lotion channel 122, air flows into the mixing channel 121 through the air flow channel 124, and the air, the water and the lotion are mixed in the mixing channel 121, so that the lotion is fully dissolved, and the lotion flows into a washing cavity of the washing machine after being fully mixed and dissolved. Therefore, after the lotion enters the mixing channel 121, the lotion is dissolved in the water flow in the mixing channel 121, and meanwhile, because the gas enters the mixing channel 121, the dissolution of the lotion can be promoted through the sufficient mixing of the gas, the water and the lotion.

Wherein the air flow flowing into the air flow channel 124 may utilize the negative pressure generated by the flow of the water flow in the mixing channel 121 as the driving force, so that the air is sucked into the mixing channel 121 through the air flow channel 124, for example, the mixing channel 121 may be configured as a venturi structure; it is also possible to use a pump, a fan, or the like as power, and the gas is sucked into the mixing channel 121 through the gas flow channel 124 by the suction action of the pump or the fan. Alternatively, when the mixing passage 121 is configured as a venturi structure, the gas is sucked into the mixing passage 121 through the gas flow passage 124 by using both the negative pressure generated by the flow of the water flow in the mixing passage 121 and the suction action of the pump or the blower.

Further, when the mixing channel 121 is configured as a venturi structure, in the process of mixing the detergent, the gas and the water flow in the throat position of the mixing channel 121 (the "throat position of the mixing channel 121" means a position where the flow area of the mixing channel 121 is the smallest), since the flow area of the throat position of the mixing channel 121 is small, the water flow velocity is increased, the turbulent flow effect is good, the mixing effect is good, and the dissolving effect and the foaming effect of the detergent can be further improved, and the washing effect can be improved.

According to some alternative embodiments of the present invention, referring to fig. 3, 5 and 7, the pressure relief channel 123 can be communicated with and isolated from the inner cavity of the water passage member 2 by the movement of the water passage member 2, a first communication port 1111 for communicating the water passage channel 111 and the pressure relief channel 123 is formed on the side wall of the water passage channel 111, a second communication port 1211 for communicating the mixing passage channel 121 and the air passage channel 124 is formed on the side wall of the mixing passage channel 121, and a pressure relief port 212 is formed on the side wall of the water passage member 2. When at least a part of the pressure relief port 212 is opposite to the first communication port 1111, the pressure relief passage 123 is communicated with the inner cavity of the water passage member 2; when the pressure relief port 212 is offset from the first communication port 1111, the pressure relief passage 123 is blocked from the inner cavity of the water passage member 2. Therefore, through the arrangement, the communication and the separation of the pressure relief channel 123 and the inner cavity of the water passing piece 2 can be conveniently realized, and the structure is simple.

Specifically, when water flows are introduced into the water flow channel 111 and the water inlet pressure is lower than the set pressure (see fig. 7), the pressure relief port 212 is staggered with the first communication port 1111, the pressure relief channel 123 is isolated from the inner cavity of the water passing piece 2, water flowing into the water flow channel 111 flows into the mixing channel 121 after passing through the water passing piece 2, the lotion flows into the lotion channel 122 through the lotion channel 122, air flows into the mixing channel 121 through the air flow channel 124, and the air, the water and the lotion are mixed in the mixing channel 121, so that the lotion is fully dissolved, and the lotion flows into the washing cavity of the washing machine after being fully mixed and dissolved. When water flows into the water flow channel 111 and the water inlet pressure is not lower than the set pressure (see fig. 7), at least a part of the pressure relief port 212 is opposite to the first communication port 1111, the pressure relief channel 123 is communicated with the inner cavity of the water passage member 2, after the water flows into the water flow channel 111 and passes through the water passage member 2, a part of the water flows in the water passage member 2 flows into the mixing channel 121, and the other part of the water flows in the water passage member 2 flows to the pressure relief channel 123. When water flows into the water flow channel 111 and the water inlet pressure is not lower than the set pressure, the gas may flow into the mixing channel 121 through the gas flow channel 124, or the gas cannot flow into the mixing channel 121 through the gas flow channel 124.

For example, in some embodiments, the pressure relief channel 123 and the gas flow channel 124 may be two separate channels, and gas may flow into the mixing channel 121 through the gas flow channel 124 regardless of whether the pressure of the incoming water is lower than the set pressure.

For another example, in other embodiments, the pressure relief channel 123 and the airflow channel share a channel, and when the water inlet pressure is lower than the set pressure, the gas can flow into the mixing channel 121 through the airflow channel 124; when the water inlet pressure is not lower than the set pressure, the gas cannot enter the mixing channel 121 through the gas flow channel 124 because the pressure relief channel 123 and the gas flow channel 124 share one channel and the water flow occupies the pressure relief channel 123 at the moment.

In some alternative embodiments of the present invention, referring to fig. 3, 5 and 7, the pressure relief channel 123 can be communicated with and isolated from the inner cavity of the water passage 2 by the movement of the water passage 2, a first communication port 1111 for communicating the water passage 111 and the pressure relief channel 123 is formed on the side wall of the water passage 111, a second communication port 1211 for communicating the mixing passage 121 and the air passage 124 is formed on the side wall of the mixing passage 121, the pressure relief channel 123 and the air passage 124 share one channel, and a pressure relief port 212 is formed on the side wall of the water passage 2. When at least a part of the pressure relief port 212 is opposite to the first communication port 1111, the pressure relief passage 123 is communicated with the inner cavity of the water passage member 2; when the pressure relief port 212 is offset from the first communication port 1111, the pressure relief passage 123 is blocked from the inner cavity of the water passage member 2. Therefore, through the arrangement, the communication and the separation of the pressure relief channel 123 and the inner cavity of the water passing piece 2 can be conveniently realized, and the structure is simple. Also, the structure of the mixing conveyor 100 can be simplified by sharing one passage for the relief passage 123 and the air flow passage 124.

Specifically, when water flows are introduced into the water flow channel 111 and the water inlet pressure is lower than the set pressure (see fig. 7), the pressure relief port 212 is staggered with the first communication port 1111, the pressure relief channel 123 is isolated from the inner cavity of the water passing piece 2, because the pressure relief channel 123 and the air flow channel 124 share one channel and the channel is used as the air flow channel 124 at the time, the water flowing into the water flow channel 111 flows into the mixing channel 121 after passing through the water passing piece 2, the lotion flows into the lotion channel 122 through the lotion channel 122, the gas flows into the mixing channel 121 through the air channel, and the gas, the water and the lotion are mixed in the mixing channel 121, so that the lotion is sufficiently dissolved and flows into the washing cavity of the washing machine after being sufficiently mixed and dissolved. When water flows into the water flow channel 111 and the water inlet pressure is not lower than the set pressure (refer to fig. 7), at least a part of the pressure relief port 212 is opposite to the first communication port 1111, the pressure relief channel 123 is communicated with the inner cavity of the water passing member 2, because the pressure relief channel 123 and the air flow channel 124 share one channel and the water flows occupy the pressure relief channel 123, air cannot enter the mixing channel 121 through the air flow channel 124, the channel is used as the pressure relief channel 123, after the water flows entering the water flow channel 111 pass through the water passing member 2, a part of the water flows in the water passing member 2 flow into the mixing channel 121, and the other part of the water flows in the water passing member 2 flow to the pressure relief channel 123.

Alternatively, referring to fig. 3, 5, and 7, the first communication port 1111 and the second communication port 1211 are the same communication port. Therefore, the manufacturing process can be simplified, and the processing is convenient. It should be noted that the first communication port 1111 is formed on the side wall of the water flow channel 111 and may extend to the side wall of the mixing channel 121, and the second communication port 1211 is formed on the side wall of the mixing channel 121 and may extend to the side wall of the water flow channel 111, so that the first communication port 1111 and the second communication port 1211 may be the same communication port.

In some alternative embodiments of the invention, referring to fig. 3, 5 and 7, the mixing channel 121, the lotion channel 122 and the air flow channel 124 are arranged side by side in spaced relationship, the mixing channel 121 being located between the lotion channel 122 and the air flow channel 124. The mixing channel 121, the lotion channel 122 and the air flow channel 124 may be arranged substantially in parallel, and the water flow channel 111 and the mixing channel 121 may be arranged coaxially. Thereby, the respective channels of the mixing conveyor 100 are distributed reasonably, so that the overall structure of the mixing conveyor 100 is compact and convenient to manufacture.

According to some embodiments of the present invention, referring to fig. 3, 5 and 7, the water passage member 2 has an inlet 211 and an outlet 221, the water flow is adapted to enter the water passage member 2 from the inlet 211 and flow out from the outlet 221 to the mixing channel 121, the outlet 221 may be adjacent to the mixing channel 121 or the outlet 221 may be located within the mixing channel 121. The water passage member 2 includes a main body section 21 and a pressurizing section 22 connected, the pressurizing section 22 is connected to a side of the main body section 21 adjacent to the mixing passage 121, a flow area of the pressurizing section 22 is smaller than that of the main body section 21, an inlet 211 is formed in the main body section 21, and an ejection port 221 is formed in the pressurizing section 22. Therefore, in the process that water flows through the water passing member 2, the water can be pressurized through the pressurizing section 22 of the water passing member 2, and the water flow can be accelerated, so that the water flow can be sprayed out from the spray opening 221 to the mixing channel 121 at a high speed, the impact force of the water flow is increased, the water and the lotion are sufficiently mixed and foamed in the mixing channel 121, or the water, the lotion and the gas are sufficiently mixed and foamed in the mixing channel 121.

Further, referring to fig. 3, 5 and 7, the flow area of the pressurizing section 22 decreases in the direction from the main body section 21 to the pressurizing section 22. Thereby, the water flow can be gradually accelerated during the water flow passing through the pressurizing section 22, so that the pressure and speed of the water flow can be better increased, and the flow loss can be reduced during the water flow from the main body section 21 to the pressurizing section 22.

According to some embodiments of the present invention, referring to fig. 3, 5 and 7, a first buffer chamber 13 is formed in the mixing conveyor body 1, the first buffer chamber 13 communicates with the wash passage 122 and the mixing passage 121, and a flow area of the first buffer chamber 13 is larger than a flow area of the wash passage 122. Therefore, through the first buffer chamber 13 formed in the mixing conveyor body 1, the lotion flowing into the lotion channel 122 flows into the mixing channel 121 after flowing through the first buffer chamber 13, and in the process that the lotion flows into the lotion channel 122 and flows into the mixing channel 121, because the flow direction of the lotion is changed, the flow loss of the lotion can be reduced through the buffering effect of the first buffer chamber 13, and the flow of the lotion is smoother.

In some alternative embodiments of the present invention, referring to fig. 3, 5 and 7, an air flow passage 124 communicating with the mixing passage 121 is formed in the mixing conveyor body 1, a second buffer chamber 14 is formed in the mixing conveyor body 1, the second buffer chamber 14 communicates with the air flow passage 124 and the mixing passage 121, and the flow area of the second buffer chamber 14 is larger than that of the air flow passage 124. Therefore, through the second buffer chamber 14 formed in the mixing conveyor body 1, the air flowing into the air flow channel 124 flows into the mixing channel 121 after flowing through the second buffer chamber 14, and in the process that the air flows into the lotion channel 122 and flows into the mixing channel 121, because the flow direction of the air flow is changed, the flow loss of the air flow can be reduced through the buffer effect of the second buffer chamber 14, and the flow of the air flow is smoother.

According to some embodiments of the present invention, referring to fig. 3, 5 and 7, the mixing conveyor body 1 comprises a first body 11 and a second body 12 which are detachably connected, a water flow channel 111 is formed at the first body 11, a mixing channel 121, a lotion channel 122 and a pressure relief channel 123 are formed at the second body 12, the mixing channel 121, the lotion channel 122 and the pressure relief channel 123 are arranged side by side at intervals, for example, the mixing channel 121, the lotion channel 122 and the pressure relief channel 123 may be arranged substantially in parallel. Thus, by providing the mixing conveyor body 1 to include the first body 11 and the second body 12 detachably connected, the processing formation of the cavity structure (e.g., the water flow passage 111, the mixing passage 121, the pressure relief passage 123, and the lotion passage 122) in the mixing conveyor 100 is facilitated, and the cleaning of the cavity structure in the mixing conveyor 100 is facilitated.

In addition, referring to fig. 3, 5 and 7, when the first buffer chamber 13 and the second buffer chamber 14 are formed in the mixing conveyor body 1, the first buffer chamber 13 and the second buffer chamber 14 are defined between the first body 11 and the second body 12, so that the first buffer chamber 13 and the second buffer chamber 14 are conveniently formed, and the first buffer chamber 13 and the second buffer chamber 14 are conveniently cleaned.

Further, referring to fig. 3, 5 and 7, one of the first body 11 and the second body 12 is formed with a positioning protrusion 125, and the other of the first body 11 and the second body 12 is formed with a positioning groove 112 engaged with the positioning protrusion 125, for example, when the positioning protrusion 125 is formed on the first body 11, the positioning groove 112 is formed on the second body 12, and when the positioning groove 112 is formed on the first body 11, the positioning protrusion 125 is formed on the second body 12. The first body 11 is formed with a first fastening hole 113, the second body 12 is formed with a second fastening hole 126, and a fastening member is inserted through the first fastening hole 113 and the second fastening hole 126 to connect the first body 11 and the second body 12. Thus, when the hybrid conveyor 100 is assembled, the preliminary coupling positioning between the first body 11 and the second body 12 can be achieved by the cooperation of the positioning groove 112 and the positioning protrusion 125, and the reliable coupling between the first body 11 and the second body 12 can be achieved by the fastening members inserted through the first fastening holes 113 and the second fastening holes 126. Moreover, the connection mode facilitates assembly and disassembly of the components of the hybrid conveyor 100, and also facilitates cleaning of the inner cavity structure of the hybrid conveyor 100.

Alternatively, the positioning projection 125 and the positioning groove 112 may each be formed in a ring shape extending in the circumferential direction of the first body 11 and the second body 12.

Alternatively, referring to fig. 3, 5 and 7, a sealing member 15 is provided between the positioning projection 125 and the inner wall of the positioning groove 112. Thus, by providing the sealing member 15 between the positioning projection 125 and the inner wall of the positioning groove 112, a sealing function can be provided to prevent the fluid of the cavity structure in the mixing conveyor 100 from leaking.

According to some embodiments of the present invention, referring to fig. 3, 5 and 7, a check valve 5 for opening and closing the water flow passage 111 is provided in the water flow passage 111, the check valve 5 is provided on a side of the water passage 2 away from the mixing passage 121, and the check valve 5 is in one-way communication in a direction from the water flow passage 111 to the mixing passage 121. Therefore, by arranging the check valve 5 in the water flow channel 111, the water flow carrying the lotion in the mixing conveyor 100 can be prevented from flowing back to the water inlet pipe of the washing machine, and the lotion residue in the water inlet pipe can be avoided or reduced.

In some alternative embodiments of the invention, referring to fig. 3, 5 and 7, a positioning ring 4 is arranged in the water flow passage 111, the positioning ring 4 is positioned between the water passing member 2 and the one-way valve 5, a water passing port 41 is defined in the positioning ring 4, and the one-way valve 5 is adapted to abut against the positioning ring 4 when the one-way valve 5 opens the water flow passage 111. For example, the retainer ring 4 may be fixed to an inner wall of the water passage 111, and the water passage opening 41 is defined in the retainer ring 4, and the water entering the water passage 111 may enter the water passage member 2 through the water passage opening 41. When the check valve 5 opens the water flow passage 111, the check valve 5 moves toward the direction approaching the water passage 2, and the check valve 5 is adapted to be stopped against the retainer ring 4. Therefore, the positioning ring 4 has a limiting function, and the one-way valve 5 can be prevented from being difficult to reset due to the fact that the movement distance of the one-way valve 5 is too large.
