Description
Technical Field
The invention relates to the technical field of bathroom products, in particular to an oscillator unit and a water outlet device.
Background
The fluidic oscillator may reciprocally sweep fluid emitted from the fluidic oscillator. In addition, the fluid oscillator mainly depends on the coanda effect and the shape of a runner in the fluid oscillator to realize the effect, a driving part such as a motor is not required to be arranged in the fluid oscillator, and the fluid oscillator does not need to drive a certain part to swing back and forth through the motor to realize the effect of fluid reciprocating sweeping.
Some water outlets on the market (e.g. shower, faucet) are integrated with a fluid oscillator. The water mixes with the air in the fluidic oscillator during the flow of the water in the fluidic oscillator, and thus the water flowing out of the fluidic oscillator contains a certain amount of oxygen. In general, oxygen-enriched water (oxygen-enriched water) has a health care effect on the human body, and the water flow containing oxygen is softer and less prone to skin irritation. However, in the prior art, the mixing of water and air within the fluidic oscillator is insufficient, which is detrimental to increasing the oxygen content of the water stream emitted by the fluidic oscillator.

Since at least a portion of the engagement flow passage extends in the third direction, a flow path of the air flowing from the inlet end to the outlet end of the feedback flow passage is more meandering, a pressure loss of the air during this flow is increased, and a flow velocity of the air flowing out of the feedback flow passage is reduced. As the flow rate of the air decreases, the residence time of the air in the primary flow passage increases, thereby facilitating adequate mixing of the water and air.
According to some embodiments of the invention, the engagement flow channel comprises: a first transverse segment extending in the third direction, the first transverse segment in communication with the second end; a second lateral section extending along the third direction, the second lateral section in communication with the third end; and the two ends of the longitudinal section in the first direction are respectively communicated with the first transverse section and the second transverse section, and the longitudinal section and the feedback flow channel are arranged at intervals in the third direction.

(2) The feedback flow channel and the connecting cavity on the same side are communicated with each other, so that a rectification cavity shared by a plurality of oscillator units is constructed. The multiple streams or streams of gas respectively entering from the different feedback channels merge and re-split in the aforementioned rectification chamber. In this way, the multiple water flows or air flows after re-split flow out of the multiple different feedback flow channels with higher synchronism, so as to drive the water flows in the different main flow channels to deflect with higher synchronism, and further improve the synchronism of the water flows (water flows at the water outlets) of the multiple oscillator units. Because the synchronism of the water flow of the water outlet flows of the oscillator units is higher, the disorder degree of the overall water outlet effect of the water outlet device is lower.

For convenience of description of the oscillator unit and the water outlet device of the present application, the following description will first explain some terms related to fluid mechanics of the present application:
(1) Coanda Effect (Coanda Effect): the fluid leaves the original moving direction and flows along the surface of the convex object instead.
(2) Venturi effect (Venturi effect): when the restricted fluid passes through the reduced flow cross section, the phenomenon that the flow velocity of the fluid is increased can occur; the fluid accelerates in a narrow area, thereby minimizing the pressure of the fluid where the cross section is minimized.
Fig. 1 shows an oscillator unit 101 according to an embodiment of the present invention, and fig. 2 shows the shape of a flow path of the oscillator unit 101. In the real object of the oscillator unit 101, the flow channel corresponds to a cavity or a space, but in order to conveniently show the shape of the flow channel, fig. 2 shows a structure obtained by converting the flow channel into a solid object. The holes, slits or cavities in fig. 2 correspond to solid structures in the object, e.g. the indentations 113 in fig. 2 correspond to the baffle portions 116 in the object.
Referring to fig. 1 and 2, the oscillator unit 101 includes a main flow channel 104, a water inlet 102, a water outlet 103, and a feedback flow channel 105. The water inlet 102 and the water outlet 103 are sequentially arranged along the first direction, and two ends of the main runner 104 are respectively communicated with the water inlet 102 and the water outlet 103. The feedback flow channels 105 are two, and the two feedback flow channels 105 are distributed along the second direction and are respectively positioned at two sides of the main flow channel 104. In fig. 1 and 2, the first direction is a top-down direction, and the second direction is a left-right direction. As shown in fig. 1, the main flow channel 104 and the feedback flow channel 105 may be formed as follows: the oscillator unit 101 includes a chamber 125 and two flow guide portions 114, the flow guide portions 114 being disposed in the chamber 125, the two flow guide portions 114 being disposed at intervals so as to form a main flow passage 104 between the two flow guide portions 114, one flow guide portion 114 being disposed at intervals from a wall surface of the chamber 125 so as to form a feedback flow passage 105. The primary flow passage 104 and the feedback flow passage 105 may be considered as different regions of the chamber 125. As shown in fig. 2, the feedback flow channel 105 comprises an inflow section 106 and an outflow section 107, the inflow section 106 comprising a first end 108 and a second end 109, the outflow section 107 comprising a third end 110 and a fourth end 111, the first end 108 being in communication with the water outlet 103 and functioning as an inlet end of the feedback flow channel 105, the fourth end 111 being in communication with the main flow channel 104 and functioning as an outlet end of the feedback flow channel 105. The outlet end of the feedback flow passage 105 is closer to the water inlet 102 than the inlet end of the feedback flow passage 105. In the present embodiment, the two flow guiding portions 114 are symmetrical, and the shape of the oscillator unit 101 itself is also symmetrical. The oscillator unit 101 may be made of plastic, stainless steel, or other materials that are rust-proof.
Referring to fig. 1 and 2, the oscillator unit 101 further includes two joint flow passages 112 and two baffle portions 116. Two feedback channels 105 belonging to the same oscillator unit 101 are each in communication with one junction channel 112. For example, the left joint flow channel 112 communicates with the left feedback flow channel 105, and the right county flow channel communicates with the right feedback flow channel 105. At least a portion of the engagement flow channel 112 extends in a third direction, any two of the first direction, the second direction, and the third direction being perpendicular to each other. In fig. 2, the third direction is the front-rear direction. A feedback flow path 105 and a junction flow path 112 communicating with each other satisfy the following conditions: the second end 109 and the third end 110 of the feedback flow path 105 are both in communication with the junction flow path 112, and the baffle 116 (the position of the notch 113 in fig. 2 is the actual position of the baffle 116) separates the second end 109 from the third end 110.
The operation principle of the oscillator unit 101 is shown in fig. 3 and 4, and in fig. 3 and 4, solid arrows indicate the flow path of water and broken arrows indicate the flow path of air. The surface of the diversion portion 114 facing the main flow passage 104 is a diversion surface 115 (as shown in fig. 3), and after the water enters the main flow passage 104 from the water inlet 102, the water flows along the diversion surface 115 of the diversion portion 114 due to the coanda effect. When water initially enters the main flow passage 104, it is random along which of the flow guide portions 114 the water flows, but this does not affect the final water output effect of the oscillator unit 101.
Assuming that the water flows along the right-hand flow guide 114, the water flows along the right-hand flow guide 114 to the inlet end (bottom end) of the left-hand feedback flow passage 105 as shown in fig. 3. Subsequently, a part of the water enters the left feedback flow passage 105 and flows back to the top end of the main flow passage 104, and another part of the water flows out along the left side wall surface of the water outlet 103. Based on Bernoulli's principle, the greater the flow velocity, the less the pressure. Since water continuously enters the main flow channel 104 from the water inlet 102, a negative pressure is formed at the junction of the water inlet 102 and the main flow channel 104, and this negative pressure can drive the water of the feedback flow channel 105 on the left side to flow back to the top end of the main flow channel 104, and drive the air outside the oscillator unit 101 to enter the oscillator unit 101 from the water outlet 103. Due to the blocking effect of the water in the vicinity of the water outlet 103, the incoming oscillator unit 101 flows mainly along the feedback flow passage 105 on the right side to the top end of the main flow passage 104 (the above negative pressure can drive the air flow). The air flowing out of the feedback flow passage 105 on the right side is mixed with the water flowing out of the feedback flow passage 105 on the left side, and the water mixed with the air finally flows out of the water outlet 103.
As shown in fig. 3, the orientation of the water inlet 102 is not parallel to the orientation of the outlet end of the feedback flow passage 105. Therefore, after the air flowing from the feedback flow passage 105 on the right side into the top end of the main flow passage 104 merges with the water subsequently entering the main flow passage 104, the air pushes the water flow to deflect, the merged water flow will deflect to the left, and the merged water flow flows along the diversion portion 114 on the left side (as shown in fig. 4). In general, since the frictional resistance between the air and the inner wall surface of the flow path is smaller than the frictional resistance between the water and the inner wall surface of the flow path, the kinetic energy loss of the air in the feedback flow path 105 is small, the kinetic energy of the air flowing out of the feedback flow path 105 is large, and the air flowing out of the feedback flow path 105 mainly acts on the deflection of the water flow.
As shown in fig. 4, the water flows along the left diversion portion 114 to the inlet end (bottom end) of the right feedback flow passage 105, and then, a part of the water flows back from the right feedback flow passage 105 to the top end of the main flow passage 104, and another part of the water flows out along the right side wall surface of the water outlet 103. At the same time, air enters from the water outlet 103 and flows along the left feedback flow passage 105 to the top end of the main flow passage 104, and the air flowing out of the feedback flow passage 105 is then mixed with water and pushes the water flow near the water inlet 102 to turn, so that the water in the main flow passage flows again along the right guide part 114 (as shown in fig. 3). Thus, at a certain moment, the flow paths of water and air are as shown in fig. 3; and at another time the flow paths of water and air are as shown in figure 4. The direction of the water flow exiting the water outlet 103 is periodically changed, and the water flow is reciprocally oscillated for a long period of time.
In the prior art, the oscillator unit 101 is not provided with the baffle portion 116, and the second end 109 and the third end 110 are directly connected. As a result, the flow velocity of the air in the feedback flow passage 105 is relatively high, and the flow velocity of the air after entering the main flow passage 104 is still relatively high, which results in a short residence time of the air in the main flow passage 104, and thus the air and the water cannot be sufficiently mixed in the main flow passage 104.
The oscillator unit 101 of the present invention has a baffle 116 and a joint flow path 112. Since the baffle portion 116 separates the second end 109 from the third end 110, air needs to enter and exit the joint flow passage 112 halfway during the flow of air from the inlet end to the outlet end of the feedback flow passage 105. Since at least a portion of the junction flow path 112 extends in the third direction, the flow path of the air flowing from the inlet end to the outlet end of the feedback flow path 105 is more tortuous, the pressure loss of the air during this flow is increased (compared to the prior art), and the flow rate of the air flowing out of the feedback flow path 105 is reduced. As the flow rate of the air decreases, the residence time of the air in the primary flow channel 104 increases, thereby facilitating thorough mixing of the water and air.
The shape of the engagement flow passage 112 may be set to the shape shown in fig. 2. Referring to fig. 2, the joint flow channel 112 includes a first transverse section 117, a second transverse section 118, and a longitudinal section 119. Both the first 117 and second 118 transverse sections extend in a third direction, the first 117 and second 109 transverse sections communicating with the second 118 transverse sections communicating with the third 110 end. The longitudinal section 119 communicates with the first and second lateral sections 117, 118 at both ends in the first direction, respectively, and the longitudinal section 119 and the feedback flow passage 105 are disposed at intervals in the third direction. The baffle portion 116 is disposed between the first transverse section 117 and the second transverse section 118. In this arrangement, the shape of the joint flow path 112 is relatively simple, and the processing difficulty of the oscillator unit 101 is relatively low.
In addition, to reduce the difficulty of machining, the first transverse section 117, the second transverse section 118, and the longitudinal section 119 may each be provided in a rectangular shape; accordingly, the baffle portion 116 is rectangular.
In other embodiments, not shown, the engagement flow channel 112 may also be configured to: at least a portion of the engagement flow channel 112 extends in the second direction. This arrangement also increases the tortuosity of the air flow path, thereby facilitating thorough mixing of the water and air. Specifically, if at least a portion of the joining flow channel 112 extends along the second direction, the joining flow channel 112 shown in fig. 2 may be adjusted to: the first and second lateral sections 117, 118 each extend in a second direction, and the longitudinal sections 119 and feedback flow channels 105 are spaced apart in the second direction.
The structure of the oscillator unit 101 is further described below.
As shown in fig. 1, the main runner 104 includes a through hole 120, and the wall surface of the main runner 104 includes two diversion surfaces 115 spaced apart along the second direction, where one end of the diversion surface 115 near the water inlet 102 is a proximal end, and the two proximal ends are disposed between each other to form the through hole 120. In fig. 1, the proximal end of the flow guiding surface 115 is the tip of the flow guiding surface 115. The outlet end of the feedback flow passage 105 is located between the through port 120 and the water inlet 102, the cross-sectional area of the through port 120 is S 2, and the cross-sectional area of the water inlet 102 is S 1,S1<S2. The cross-sectional area of the water inlet 102 refers to the area of the cross-section taken through a plane (e.g., a horizontal plane) perpendicular to the axis of the water inlet 102 to intercept the water inlet 102. The cross-sectional area of the through-opening 120 refers to an area of a cross-section taken through the through-opening 120 by a plane (e.g., a horizontal plane) perpendicular to the axis of the through-opening 120. In the case of S 1<S2, the pressure of water located between the water inlet 102 and the through port 120 is small, that is, the pressure of the outlet end of the feedback flow passage 105 is small, based on the venturi effect. This creates a negative pressure at the outlet end of the feedback flow channel 105, thereby facilitating the outflow of fluid from the outlet end of the feedback flow channel 105.
As shown in fig. 1, the end of the guide surface 115 remote from the water inlet 102 is a distal end, and the distance between the two proximal ends is smaller than the distance between the two distal ends. In fig. 1, the distal end of the guide surface 115 is the bottom end of the guide surface 115. In the first direction, the distance between the two flow guiding surfaces 115 increases and then decreases. In this way, the main flow channel 104 is in a water drop shape, and after the water leaves from the diversion surface 115 on one side (for example, the diversion surface 115 on the right side), the water can be guided to the wall surface on the other side of the water outlet 103 (for example, the left wall surface of the water outlet 103) by the diversion surface 115, so that the water flows out along one of the wall surfaces of the water outlet 103.
As shown in fig. 3, the wall surface of the water outlet 103 includes two outlet walls 124, and the two outlet walls 124 are spaced apart along the second direction, and the distance between the two outlet walls 124 gradually increases along the first direction. This arrangement causes the outlet 103 to be flared, thereby facilitating an increase in the maximum angle of flow at the outlet 103. The inlet ends of the feedback flow channels 105 are disposed on the outlet walls 124, one inlet end being disposed on each of the outlet walls 124. In this way, the inlet end of the feedback flow channel 105 is disposed obliquely downward, so that air at the water outlet 103 can enter the feedback flow channel 105.
As shown in fig. 5 to 12, the present invention further provides a water outlet device 121. Fig. 11 and 12 show a structure obtained by converting the flow channel of the water outlet device into a solid. The joint flow paths 112 in the water outlet means 121 may be shared. It is assumed that the water outlet device 121 includes N oscillator units 101 (N is an integer and N is equal to or greater than 2), and that the water outlet device 121 has only 2 joint flow channels 112 regardless of N.
Unlike the above, in the water outlet device 121 described below, the joint flow passage 112 is not divided into a part of the oscillator unit 101. The concept of the water outlet means 121 to extend the air flow path is the same as that of the oscillator unit 101 above.
The water outlet device includes a baffle portion 116, a flow dividing flow passage 122, two joint flow passages 112, and a plurality of oscillator units 101. As shown in fig. 10, the oscillator unit 101 includes a water inlet 102, a water outlet 103, a main flow passage 104, and two feedback flow passages 105, a shunt flow passage 122 communicates with the water inlet 102, and the water inlet 102 and the water outlet 103 are sequentially arranged in the first direction. Two ends of the main flow passage 104 are respectively communicated with the water inlet 102 and the water outlet 103, and two feedback flow passages 105 are distributed along the second direction and are respectively positioned at two sides of the main flow passage 104. The feedback flow channel 105 comprises an inflow section 106 and an outflow section 107, the inflow section 106 comprising a first end 108 and a second end 109, the outflow section 107 comprising a third end 110 and a fourth end 111, the first end 108 being in communication with the water outlet 103 and being the inlet end of the feedback flow channel 105, the fourth end 111 being in communication with the main flow channel 104 and being the outlet end of the feedback flow channel 105. Two feedback flow channels 105 belonging to the same oscillator unit 101 are each in communication with one joint flow channel 112, at least a portion of the joint flow channel 112 extending in the second direction or the third direction (the joint flow channel 112 extending in the third direction in the embodiment shown in fig. 11). For one feedback flow channel 105 and one junction flow channel 112 communicating with each other: the second end 109 and the third end 110 are in communication with the junction flow channel 112, and the second end 109 and the third end 110 are separated by a baffle portion 116. The water outlet means 121 further comprises a main inlet 123 (as shown in fig. 8) and a flow diversion channel (as shown in fig. 11). The flow dividing channel 122 is communicated with the water inlet 102, the flow dividing channel 122 extends along the third direction, and water flowing into the water outlet device 121 from the main inlet 123 is divided into different water inlets 102 through the flow dividing channel 122.
In this arrangement, the water outlet device 121 can also mix water and air sufficiently and then flow out. Also, as shown in fig. 11, in this arrangement, the feedback flow paths 105 and the junction chambers on the same side (e.g., both on the right side or both on the left side) communicate with each other, thereby constructing a "rectification chamber" common to the plurality of oscillator units 101. The multiple streams or streams of gas respectively entering from the different feedback channels 105 merge and redistribute in the rectification chamber. In this way, the multiple water flows or air flows after re-splitting flow out from the multiple different feedback flow channels 105 with high synchronicity, so as to drive the water flows in the different main flow channels 104 to deflect with high synchronicity, and further improve synchronicity of the water outlet flows (water flows at the water outlets 103) of the multiple oscillator units 101. Because the synchronicity of the water flows of the plurality of oscillator units 101 is higher, the overall water outlet effect of the water outlet device 121 is less disordered, the washing strength of the water flow of the water outlet device 121 is more uniform, and the visual effect of the water flow of the water outlet device 121 is better.
As shown in fig. 11, all the oscillator units 101 are distributed along a straight line (not shown) extending in the third direction. This arrangement is advantageous in reducing the difficulty of layout of the oscillator unit 101 and in manufacturing the water outlet device 121. In addition, since the oscillator units 101 are distributed along the above straight line, the lengths and shapes of the two joining runners 112 can be made identical. As such, the flow rate or flush strength of the water flow at the water outlet 103 is substantially uniform (no consideration is given to the angle of the water flow here) regardless of whether the fluid within the fluidic oscillator is flowing along the path shown in fig. 3 or the path shown in fig. 4.
As shown in fig. 8, for one joint flow channel: two baffle portions 116 are arranged between the first transverse section 117 and the second transverse section 118, the two baffle portions 116 are distributed at intervals along the third direction, the two baffle portions 116 are respectively located on two sides of the longitudinal section 119, and the two baffle portions 116 are symmetrically arranged based on the longitudinal section 119. In this arrangement, the engagement flow passage 112 is generally "I" shaped. The arrangement can prevent the overlong flow path of the fluid passing through a certain feedback flow passage 105, improve the difference of the water outlet effects of the two front-back symmetrical oscillator units 101, and reduce the mess degree of the overall water outlet effect of the water outlet device 121.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
