Description

Valve and water outlet device

Technical Field

The utility model relates to the technical field of bathroom products, in particular to a valve and a water outlet device.

Background

There is one such device in the prior art: the device is internally stored with a substance required, through which the fluid is mixed with the substance stored inside the device, and the water exiting the device is mixed with the substance. For example, there are beauty-care showers on the market, in which a skin-beautifying agent is stored, which is rich in collagen, and water flowing out of the shower contains the skin-beautifying agent. In some use scenarios, the user may want a larger water yield and a lower consumption rate of the skin-beautifying agent in order to save the skin-beautifying agent. However, the consumption rate of the skin-beautifying agent in the skin-beautifying shower is closely related to the water pressure or flow rate of the shower, and the higher the water yield of the shower is, the higher the consumption rate of the skin-beautifying agent is, which makes it difficult for the skin-beautifying shower in the prior art to satisfy the needs of the user.

Disclosure of utility model

The present utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a valve which allows the rate of consumption of the substance to be mixed (for example a skin-beautifying agent) to be adjusted and which does not increase or decrease in synchronization with the total water output of the valve.

The utility model also provides a water outlet device comprising the valve.

An embodiment of a valve according to the first aspect of the present utility model includes: the shell is provided with a water inlet, a water outlet, a main flow channel and a storage cavity, wherein the water inlet is communicated with the main flow channel, and the storage cavity is used for storing substances to be mixed; the valve core assembly comprises a static plate and a first moving plate, wherein the static plate comprises a second water passing port and a first water passing port, the water inlet, the main runner, the second water passing port and the water outlet can be communicated in sequence, the first moving plate is provided with a first control port, and when the first water passing port is communicated with the first control port, the water inlet, the main runner, the storage chamber, the first water passing port, the first control port and the water outlet are communicated in sequence; the first control port comprises a first water passing area, the first water passing area is communicated with the first water passing port, and the first moving plate can move relative to the static plate so as to change the size of the first water passing area.

The valve according to the embodiment of the first aspect of the utility model has at least the following beneficial effects: if the flow rate of water flowing along the second path is denoted as Q ₂, the flow rate of water flowing along the first path is denoted as Q ₁, and the total water output of the valve (the flow rate of water flowing out of the water outlet) is denoted as Q _{Total (S)}, then Q _{Total (S)}＝Q₂+Q₁. The water flowing along the first path contains the substance to be mixed, and the greater the Q ₁, the higher the consumption rate of the substance to be mixed. Because the size of the first water passing area can be changed along with the movement of the first moving plate, Q ₁ can be adjusted by moving the first moving plate relative to the static plate.

Fig. 1 shows a valve 100 according to an embodiment of the present utility model, and fig. 2 is an exploded view of the valve 100 shown in fig. 1. As shown in fig. 2, the valve 100 includes a housing 101, and the housing 101 is provided with a water inlet 201, a water outlet 202, and a main flow path 203. Fig. 8 is a cross-sectional view of the valve 100 shown in fig. 1, and as shown in fig. 8, the housing 101 is further provided with a storage chamber 204, and the storage chamber 204 is used for storing substances to be mixed. The substances to be mixed are not shown in the figures. The substances to be mixed may be skin beautifying agents containing collagen, or other substances which need to be mixed with the fluid in the main flow channel 203, for example, the substances to be mixed may also be scale inhibitors, bactericides and the like. The substance to be mixed stored in the storage chamber 204 may be liquid, solid, or gas.

The following description will be made with the skin-beautifying agent as the substance to be mixed, but in other embodiments, the skin-beautifying agent may be replaced with other kinds of substances to be mixed. Also, while the following description uses water as the fluid into and out of the valve 100, and certain structural features of the valve 100 of the present utility model include the word "water," the valve 100 of the present utility model is not limited to controlling the flow of water, and water into and out of the valve 100 may be replaced with gas or other liquids than water.

Fig. 3 is an exploded view of the valve cartridge assembly 106 of fig. 2, as shown in fig. 2 and 3, the valve 100 includes the valve cartridge assembly 106, the valve cartridge assembly 106 including a stationary plate 302 and a first moving plate 304. As shown in fig. 4, the stationary plate 302 is provided with a second water passing port 406 and a first water passing port 404, and the second water passing port 406 and the first water passing port 404 are distributed at intervals. As shown in fig. 5, the first movable piece 304 is provided with a first control port 410.

The water inlet 201, the main runner 203, the second water passing port 406 and the water outlet 202 are communicated in turn. The ability of these four to communicate sequentially may mean that the four communicate sequentially when the valve 100 is in certain states (i.e., the examples described in detail below); in other embodiments, the ability to communicate sequentially may also mean that the four communicate sequentially regardless of the valve 100 being in any state. In addition, when the first water passing port 404 communicates with the first control port 410, the water inlet 201, the main flow path 203, the storage chamber 204, the first water passing port 404, the first control port 410, and the water outlet 202 communicate in this order.

In this embodiment, the first movable plate 304 is rotatable relative to the stationary plate 302. Fig. 7 illustrates the rotation of the first rotor plate 304 relative to the stator plate 302, fig. 7 is not a cross-sectional view, and the stator plate 302 and the first rotor plate 304 in fig. 7 are provided with cross-hatching merely for convenience in distinguishing the stator plate 302 from the first rotor plate 304. The first control port 410 includes a first water passing region in communication with the first water passing port 404, i.e., a region of the first control port 410 not obscured by the static plate 302. As shown in fig. 7, the size of the first water passing area may change as the first moving plate 304 rotates relative to the stationary plate 302. The larger the first water passing area, the larger the flow rate of water passing through the first water passing port 404 and the first control port 410.

In other embodiments, the first rotor plate 304 may also move relative to the stationary plate 302, so long as movement of the first rotor plate 304 causes the first water passing region to be sized.

Fig. 8 is a cross-sectional view of the valve 100 in a first state, and fig. 9 shows a cross-sectional view of the valve 100 in a second state. In fig. 8, valve 100 is fully closed and water cannot flow out of outlet 202. In fig. 9, the water inlet 201, the main channel 203, the second water passing port 406 and the water outlet 202 are sequentially communicated. At this time, a part of the water entering the main flow path 203 from the water inlet 201 may then sequentially flow through the second water passing port 406, the second control port 407, and the water outlet 202. In fig. 9, the first water passing port 404 communicates with the first control port 410, and the water inlet 201, the main channel 203, the storage chamber, the first water passing port 404, the first control port 410, and the water outlet 202 also communicate in this order. At this time, a portion of the water entering the flow path from the water inlet 201 may then sequentially flow through the storage chamber 204, the first water passing port 404, the first control port 410, and the water outlet 202.

When the valve 100 is in the second state, for water entering the flow path from the water inlet 201, a portion of the water flows out of the water outlet 202 without flowing through the storage chamber 204, the flow path of this portion of the water being shown as a second path 502 in fig. 9; another portion of the water flows through the reservoir chamber 204 and out the water outlet 202, as shown in the first path 501 of fig. 9. The water flowing along the first path 501 will contain a skin makeup agent. If the flow rate of water flowing along the second path 502 is denoted as Q ₂, the flow rate of water flowing along the first path 501 is denoted as Q ₁, and the total water output of the valve 100 (the flow rate of water flowing out of the water outlet 202) is denoted as Q _{Total (S)}, then Q _{Total (S)}＝Q₂+Q₁.

Since the size of the first water passing area can be changed along with the movement of the first moving plate 304, the Q ₁ can be adjusted by moving the first moving plate 304 relative to the static plate 302. Since Q ₁ can be adjusted, the consumption rate of the skin-beautifying agent stored in the storage chamber 204 can be adjusted. Since there are two paths in the valve for water to flow, the first path 501 and the second path 502, even if Q _{Total (S)} is increased, the user can adjust the state of the first tab 304 to decrease Q ₁, and accordingly, Q ₂ is increased. Thus, with the valve 100 of the present utility model, the consumption rate of the skin-beautifying agent may be increased or decreased in synchronization with the total water output of the valve 100, which facilitates the user to flexibly adjust the consumption rate of the skin-beautifying agent.

As shown in fig. 3, in an embodiment, the valve core assembly 106 further includes a second moving plate 303, wherein both the second moving plate 303 and the first moving plate 304 are capable of moving relative to the stationary plate 302, and wherein the movement of the second moving plate 303 is independent of the movement of the first moving plate 304. By "the movement of the second moving plate 303 is independent of the movement of the first moving plate 304" is meant that the first moving plate 304 may not move in synchronization with the second moving plate 303 when the second moving plate 303 moves relative to the stationary plate 302. It should be noted that, in some embodiments, the movement of the second moving plate 303 and the first moving plate 304 may be manually driven, and in other embodiments, the movement of the second moving plate 303 and the first moving plate 304 may be driven by a power source such as a motor.

As shown in fig. 5, the second movable piece 303 is provided with a second control port 407. As shown in fig. 9, when the second water passing port 406 communicates with the second control port 407, the water inlet 201, the main flow path 203, the second water passing port 406, the second control port 407, and the water outlet 202 communicate in this order, thereby allowing water to flow along the second path 502.

Fig. 6 illustrates the rotation of the second rotor 303 relative to the stator 302, fig. 6 is not a cross-sectional view, and the stator 302 in fig. 6 is provided with a cross-sectional line for convenience only in distinguishing the stator 302 from the second rotor 303. The second control port 407 includes a second water passing area, which is in communication with the second water passing port 406, that is, an area of the second control port 407 not blocked by the stationary blade 302. As shown in fig. 6, the second water passing area gradually increases as the second moving plate 303 rotates counterclockwise with respect to the stationary plate 302. Conversely, if the second moving plate 303 rotates clockwise relative to the stationary plate 302, the second water passing area gradually decreases. The larger the second water passing area is, the larger the flow rate of water passing through the second water passing port 406 and the second control port 407 is.

Since the size of the second water passing area can be changed along with the movement of the second moving plate 303, Q ₂ can be adjusted by moving the second moving plate 303 relative to the stationary plate 302. Thus, the provision of the second tab 303 facilitates improved flexibility in adjusting the water output of the valve 100.

As shown in fig. 8, the housing 101 further includes a chamber inlet 205 and a chamber outlet 206, both of which chamber inlet 205 and chamber outlet 206 communicate with the storage chamber 204, and the chamber outlet 206 communicates with the first water passing port 404. The valve 100 further comprises a check unit 105, the check unit 105 being mounted at the chamber inlet 205, the check unit 105 being configured to: the chamber inlet 205 is communicated with the main channel 203 when the first water passing port 404 is communicated with the first control port 410, and the chamber inlet 205 is separated from the main channel 203 when the first water passing port 404 is separated from the first control port 410. Wherein "separated from each other", i.e., not in communication with each other, the first water passing port 404 and the first control port 410 are separated from each other, meaning that the first moving plate 304 completely covers and blocks the first water passing port 404.

If the user does not need to use the water containing the skin-beautifying agent, the user can adjust the position of the first moving plate 304 so that the first water passing port 404 and the first control port 410 are separated from each other. Since the valve 100 is provided with the check unit 105, the check unit 105 can prevent the skin-beautifying agent in the storage chamber 204 from leaking into the main flow path 203 when the user does not need to use the water containing the skin-beautifying agent, and the check unit 105 is advantageous in reducing the waste of the skin-beautifying agent.

The structure of the check unit 105 is shown in fig. 8, and the check unit 105 includes a fixed member 602, a movable member 603, and an elastic member 604. The fixing member 602 is connected to the housing 101, and the fixing member 602 is provided with a non-return passage 601 having both ends penetrating therethrough, and one end (tip) of the non-return passage 601 communicates with the chamber inlet 205. The movable member 603 is movably connected with the fixed member 602, and the movable member 603 is switchable between an open position and a closed position with respect to the fixed member 602. As shown in fig. 8, when the movable member 603 is in the closed position, the movable member 603 abuts against the bottom end of the fixed member 602 to block the non-return channel 601. As shown in fig. 9, when the movable member 603 is in the open position, a gap is provided between the movable member 603 and the bottom end of the fixed member 602, the movable member 603 unblocks the non-return channel 601, and the main flow channel 203 and the chamber inlet 205 communicate through the non-return channel 601. One end of the elastic member 604 is connected to the movable member 603, the other end of the elastic member 604 is connected to the fixed member 602, and the elastic force of the elastic member 604 is used to maintain the movable member 603 in the closed position shown in fig. 8. For example, the elastic member 604 is in a compressed state, the top end of the elastic member 604 abuts against the fixed member 602, the bottom end of the elastic member 604 abuts against the piston member, and the elastic member 604 is used for driving the movable member 603 to move downward. In other embodiments, the top end of the resilient member 604 may instead be connected to the housing.

The principle of operation of the non-return unit 105 is as follows. As shown in fig. 8, when the first moving plate 304 completely covers and blocks the first water passing opening 404, the chamber outlet 206 is also blocked, the skin care agent and air in the storage chamber 204 cannot leave the storage chamber 204 from the chamber outlet 206, the chamber outlet 206 cannot serve as a pressure relief opening of the storage chamber 204, the pressure in the storage chamber 204 is kept at a higher level, the sum of the pressure in the storage chamber 204 and the elastic force of the elastic member 604 is greater than the water pressure in the main channel 203, the water in the main channel 203 is difficult to push the movable member 603, and the movable member 603 is kept at the closed position. As shown in fig. 9, when the first water passing port 404 and the first control port 410 are communicated, the chamber outlet 206 may serve as a pressure relief port of the storage chamber 204, and water in the pressure main flow passage 203 in the storage chamber 204 may push the movable member 603 away and enter the storage chamber 204.

As shown in fig. 8, the housing 101 is further provided with a charging port 207, and the charging port 207 communicates with the storage chamber 204. As shown in fig. 2, the valve 100 further includes a plug 104, where the plug 104 is detachably connected to the housing 101, and the plug 104 plugs the charging port 207. The stopper 104 prevents the skin-beautifying agent in the storage chamber 204 and water flowing through the storage chamber 204 from leaking from the charging port 207. When the skin care agent stored in the valve 100 is insufficient, the user can detach the stopper 104 and then inject the skin care agent into the storage chamber 204 from the charging port 207. Plug 104 and housing 101 may be threadably connected. In other embodiments, plug 104 may also be inserted into port 207 and plug 104 may be interference fit with port 207.

As shown in the right end of fig. 6, the second moving plate 303 can cover and block the second water passing port 406, and the area of the second water passing area is 0. As shown in the right end of fig. 7, the first moving plate 304 can cover and block the first water passing port 404, and at this time, the area of the first water passing area is 0. The above arrangement is advantageous in enhancing the versatility of the valve 100.

Specifically, as shown in fig. 10, the valve 100 further has a third state, when the valve 100 is in the third state, the first moving plate 304 completely covers the first water passing port 404, the first water passing port 404 is not communicated with the first control port 410, and the first water passing port 404 is blocked by the first moving plate 304; at this time, the second water passing port 406 communicates with the second control port 407. In this case, Q ₁＝0,Q_{Total (S)}＝Q₂, the water flowing out of the valve 100 does not contain skin-beautifying agents. When the valve 100 is in the third state, the second movable plate 303 is moved relative to the stationary plate 302, so that Q _{Total (S)} can be adjusted. In some use scenarios, if the user does not need to use water containing the skin-beautifying agent, the user can switch the valve 100 to the third state, thereby reducing the waste of the skin-beautifying agent.

As shown in fig. 11, the valve 100 further has a fourth state, when the valve 100 is in the fourth state, the second moving plate 303 completely covers the second water passing port 406, the second water passing port 406 is not communicated with the second control port 407, and the second water passing port 406 is blocked by the second moving plate 303; at this time, the first water passing port 404 communicates with the first control port 410. In this case, q2=0, Q _{Total (S)}＝Q₁. At this time, the Q _{Total (S)} can be adjusted by moving the first movable plate 304 relative to the stationary plate 302, thereby adjusting the consumption rate of the skin-beautifying agent.

When the valve 100 is in the fourth state, the consumption rate of the skin-beautifying agent becomes larger or smaller in synchronization with the total water output of the valve 100. However, it should be noted that the valve 100 of the present utility model has the second state in addition to the fourth state. In the second state, the consumption rate of the skin-beautifying agent may not be increased or decreased in synchronization with the total water output of the valve 100, and the flexibility of adjusting the consumption rate of the skin-beautifying agent is high. Moreover, the valve 100 of the present utility model has different ways of adjusting the consumption rate of the skin care agent in the second state and the fourth state, respectively.

Further, as shown in fig. 8, when the valve 100 is in the first state, the second moving plate 303 completely covers the second water passing port 406, the second water passing port 406 is blocked by the second moving plate 303, and the first moving plate 304 completely covers the first water passing port 404, and the first water passing port 404 is blocked by the first moving plate 304. When the valve 100 is in the first state, the valve 100 is fully closed and no water flows out of the water outlet 202 of the valve 100.
