Shower head with water disc cleaning function

Abstract

This application discloses a shower head with a water tray cleaning function, including a shower head body, a water tray, and a switching mechanism. The switching mechanism includes a fixed component and a rotatable switching component. The fixed component has two fluid through holes that are respectively connected to a water passage and an air passage. The switching component has a first fluid channel and a second fluid channel. When the switching component rotates to the cleaning position, the second fluid channel simultaneously aligns with both fluid through holes, connecting the air passage and the water passage. At the same time, the first fluid channel is offset from the water-side fluid through holes, closing the water passage. Compressed air enters the internal flow channel and chamber that are fluidly connected to the water tray through the water passage and is discharged through the water tray, thereby pushing residual water out. Compressed air can also be provided through an elastic enclosure component, an air inlet component, and an air outlet component, and water that accidentally enters the enclosure component can be discharged using the same air passage.

Description

Technical Field

[0001] This application belongs to the field of bathroom equipment technology, specifically relating to a shower head with a water tray cleaning function. Background Technology

[0002] Showerheads typically guide external water supply to a spray dish via internal water channels, from which the water is then sprayed outwards through the spray nozzles. During use, water can easily remain inside the water channels and in the flow paths and chambers connected to the spray dish, especially after use, as this residual water is difficult to drain promptly. Long-term accumulation of residual water can produce unpleasant odors and may affect the hygiene of the showerhead and the user experience.

[0003] Some existing showerheads use natural dripping or changing the showerhead's position to drain residual water, but the drainage effect is usually affected by factors such as the showerhead's placement and internal flow channel structure. Other showerheads have a separate air blowing structure that uses compressed air to blow away the internal water channels, but this usually requires an independent air path and a corresponding switching structure, making the showerhead's internal structure more complex.

[0004] Furthermore, when the showerhead is equipped with an airbag or other flexible air storage structure, there is a possibility that a small amount of water may accidentally enter the air storage chamber during use. Adding an independent drainage structure to address this issue would further increase the complexity of the showerhead's internal structure.

[0005] Therefore, it is necessary to provide a shower head with a compact structure that can use compressed air to drain residual water from the internal flow channels and chambers that are in fluid communication with the water outlet tray, and can easily switch between normal water flow, water stop, and cleaning states. Summary of the Invention

[0006] The present invention aims to provide a shower head with a water tray cleaning function to solve the problems of residual water inside existing shower heads being difficult to drain and the complex gas cleaning structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A shower head with a water tray cleaning function includes a shower head body, a water outlet tray, and a switching mechanism for switching the internal fluid passage of the shower head body, wherein the water outlet tray is disposed on one side of the shower head body. The switching mechanism includes a fixedly installed switching baffle and a water column that can rotate relative to the switching baffle; The switching baffle is provided with a water passage hole communicating with the water passage and an air passage hole communicating with the air passage. The water passage hole and the air passage hole are spaced apart from each other along the rotation direction of the water column. The water column is provided with a water channel, an air channel, and a blocking area outside the water channel and the air channel at one end facing the switching baffle. The water channel is used to connect water flow, and the air channel is used to connect air flow. The water column can be rotated to multiple working positions, including at least a normal water outlet position and a cleaning position; At the normal water outlet position, the water channel corresponds to the water passage hole, and the air passage hole is blocked by the blocking area to form a normal water flow path; In the clean position, the ventilation groove extends along the rotation direction of the water column and simultaneously covers the air passage and the water passage, so that the air passage is connected to the water passage through the air passage, the ventilation groove and the water passage, while the water passage is offset from the water passage to cut off the normal water flow path; When compressed air is input into the air passage at the clean position, the compressed air enters the water passage through the air inlet, the air groove and the water inlet, and is discharged outward through the water outlet chamber and the water outlet plate that are in fluid communication with the water passage, so as to push the residual water in the internal flow channel and / or chamber that are in fluid communication with the water outlet plate to be discharged.

[0008] In a preferred embodiment provided in this application, the venting groove is a recess formed at one end of the water column facing the switching baffle. When the water column and the switching baffle are engaged, the venting groove and the switching baffle together form a cavity. In the clean position, the air vent and the water vent are both located within the range corresponding to the cavity, so as to form a closed or substantially closed communication path between the air vent and the water vent.

[0009] As a preferred embodiment provided in this application, a sealing structure is provided between the water column and the switching baffle. The sealing structure is at least located outside the corresponding area of ​​the venting groove to limit gas leakage through non-predetermined locations between the water column and the switching baffle.

[0010] As a preferred embodiment provided in this application, the venting groove has an extension range along the rotation direction of the water column that is greater than the size corresponding to the angular interval between the water passage and the air passage, so that when the water column rotates to the cleaning position, the venting groove can simultaneously cover the water passage and the air passage.

[0011] As a preferred embodiment provided in this application, the shower head further includes a handle and a switching knob rotatably disposed on the handle. The water jet is disposed between the handle and the switching baffle. The switching knob is throttle-connected to the water jet so that rotating the switching knob drives the water jet to rotate between the multiple working positions.

[0012] In a preferred embodiment provided in this application, the switching knob is provided with a rotary plug, the water column is provided with a groove that mates with the rotary plug, and the handle is provided with a handle groove that allows the rotary plug to rotate. The rotary plug and the groove form a transmission engagement to transmit the rotational torque of the switching knob to the water column.

[0013] As a preferred embodiment provided in this application, the shower head further includes an enclosing component, an air inlet component, and an air outlet component. The enclosing component and the shower head body enclose a cavity, the air inlet component connects the cavity to the outside air, and the air outlet component connects the cavity to the air passage. When the enclosing member is pressed, the volume of the chamber decreases, and the air in the chamber enters the air passage through the air outlet to provide compressed air to the air passage.

[0014] As a preferred embodiment provided in this application, both the air inlet and the air outlet have a unidirectional flow structure. The air inlet is used to restrict the flow of air from the chamber to the outside air, and the air outlet is used to restrict the flow of air from the air passage to the chamber. The water outlet plate is rotatable relative to the shower head body, and there is a rotation gap between the water outlet plate and the shower head body that communicates with the outside air. The outside air enters the chamber through the rotation gap and the air inlet.

[0015] As a preferred embodiment provided in this application, the side of the shower head body connected to the air outlet is provided with a water collection groove and a water collection arc surface. The water collection arc surface is used to guide the liquid entering the chamber to the water collection groove and collect it in the area where the air outlet is located. In the clean position, the liquid entering the chamber can enter the air channel through the air outlet and be discharged outward along the fluid path formed by the air channel, the air vent, the air groove, the water vent, the water passage, and the water outlet plate.

[0016] In a preferred embodiment provided in this application, the air outlet, in the clean position, is used both to introduce compressed air from the chamber into the air passage and to introduce liquid entering the chamber into the air passage, so that the air outlet simultaneously forms an air output path and a liquid discharge path. Beneficial effects

[0017] Compared with the prior art, the present invention has the following beneficial effects: This application uses a rotatable switching component to change the connection between the water passage and the air passage, enabling the shower head to switch between normal water output, water stop, and cleaning states. The structure is compact and easy to operate.

[0018] The cleanliness state of this application is achieved by simultaneously aligning the second fluid channel with both the first and second fluid through holes, and disengaging the first fluid channel from the first fluid through hole, thus enabling the air path to connect to the original water path while simultaneously shutting off the normal water path. This eliminates the need for a completely independent clean exhaust path; the original water path can be used to guide compressed air to the internal flow channel and chamber that are fluidly connected to the water outlet pan, and residual water can be discharged from the water outlet pan.

[0019] This application can also use an elastic enclosure component to provide compressed air, and by repeatedly pressing and releasing the enclosure component, a continuous airflow circulation is formed, which is beneficial to improving the effect of residual water discharge.

[0020] Furthermore, by utilizing the water collection structure and existing clean air passages, water that accidentally enters the internal cavity of the enclosure can be drained without the need for an additional independent drainage channel, which helps to reduce the number of structures and improve reliability.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] like Figures 1 to 6As shown, this embodiment provides a shower head with a water tray cleaning function, including a shower head body 100, a water tray 106, and a handle 200. The water tray 106 is disposed on one side of the shower head body 100, and the handle 200 is connected to the lower part of the shower head body 100. In one embodiment, the handle 200 is threadedly connected to the shower head body 100.

[0030] A partition 101 is provided on the side of the shower head body 100 facing the water outlet plate 106. The partition 101 can be fixedly installed on the side wall of the shower head body 100, and in one embodiment, it is fixed to the shower head body 100 by ultrasonic welding. A cover 102 is provided between the partition 101 and the water outlet plate 106, and the cover 102 can be fixedly connected to the partition 101, and in one embodiment, it is fixed by ultrasonic welding.

[0031] The cover 102 includes an upper hollow annular portion and a lower base plate portion. The separator 101, the cover 102, and the adjacent shower head body 100 and water outlet plate 106 together form an air passage 107, a water passage 108, and a water outlet chamber 109. The air passage 107 and the water passage 108 are separated from each other in the main area and are not directly connected under normal conditions. The water passage 108 is connected to the water outlet chamber 109, and the water outlet chamber 109 corresponds to the water outlet plate 106, so that the water or clean air entering the water outlet chamber 109 can eventually be discharged outward through the water outlet plate 106.

[0032] An enclosing member 105 is provided on the side of the shower head body 100 away from the water outlet plate 106. The enclosing member 105 is elastic and forms a cavity with the shower head body 100. The enclosing member 105 as a whole can undergo elastic deformation, reducing the volume of the cavity when pressed by an external force, and recovering under its own elastic restoring force after the external force is released. An air inlet 103 and an air outlet 104 are disposed between the cavity and the outside or air passage 107, wherein the air inlet 103 is used to allow outside air to enter the cavity, and the air outlet 104 is used to allow air in the cavity to enter the air passage 107. In one embodiment, the air inlet 103 and the air outlet 104 adopt a rubber-based one-way valve structure, and the air outlet 104 can adopt a duckbill check valve, but the specific valve body structure is not limited to this.

[0033] The water outlet plate 106 is rotatable relative to the shower head body 100, and there is always a rotational gap between the water outlet plate 106 and the shower head body 100. This rotational gap communicates with the outside air and can serve as an air inlet for outside air to enter the air intake component 103. This rotational gap is not a through hole formed in the water outlet plate 106, but rather a space formed by the fit between the water outlet plate 106 and the shower head body 100. The rotation of the water outlet plate 106 is independent of the rotation of the water column 202; the water outlet plate 106 does not drive the water column 202 to rotate through its rotation.

[0034] The handle 200 internally houses a water pipe 201, a water column 202, and a switching baffle 203. The water pipe 201 is used to introduce external water into the shower head. In one embodiment, the water pipe 201 is fixed to the handle 200 using an embedded fit, interference fit, or snap-fit. The switching baffle 203 is fixedly disposed inside the shower head body 100, located below the air passage 107 and water passage 108, and in one embodiment, it is fixed using ultrasonic welding. The water column 202 is disposed between the water pipe 201 and the switching baffle 203, and is rotatable relative to both the water pipe 201 and the switching baffle 203.

[0035] The end face of the water column 202 facing the switching baffle 203 is provided with a water channel 2021, an air channel 2022, and a planar area. The water channel 2021 is used to form a water flow path, and the air channel 2022 is used to form an airflow path. The specific shapes of the water channel 2021 and the air channel 2022 can be adjusted according to the actual product structure and are not limited to a certain fixed contour. The air channel 2022 is a groove formed on the end face of the water column 202, rather than a through hole penetrating the water column 202.

[0036] The switching baffle 203 is provided with a water passage 2031 and an air passage 2032. The water passage 2031 communicates with the water channel 108, and the air passage 2032 communicates with the air channel 107. A sealing structure is provided between the end face of the water column 202 and the switching baffle 203 to reduce water or air leakage from unintended locations between the water column 202 and the switching baffle 203. The sealing structure can be a sealing ring or other structures that can achieve a sealing effect; its specific form is not limited.

[0037] A switching knob 204 is provided on the handle 200. The switching knob 204 can rotate relative to the handle 200 without needing to move axially. The switching knob 204 has a rotary plug, the water column 202 has a groove for receiving the rotary plug, and the handle 200 has a handle groove for rotating the rotary plug. The rotary plug and the groove form a transmission engagement, so that when the switching knob 204 rotates, it can transmit a rotational torque to the water column 202, thereby driving the water column 202 to rotate relative to the switching baffle 203.

[0038] The water column 202 can rotate to at least three different working positions, corresponding to the normal water outlet position, the water outlet stop position, and the cleaning position, respectively. The specific arrangement order of the three working positions can be changed according to the product structure, and this embodiment is not limited to a certain fixed order.

[0039] In the normal water outlet position, the water passage 2021 corresponds to the water passage hole 2031. Water from an external water source sequentially enters the water outlet chamber 109 through the water passage pipe 201, water passage 2021, water passage hole 2031, and water channel 108, and is sprayed outward through the water outlet plate 106. At this time, the air passage hole 2032 corresponds to the blocking area of ​​the water column 202, so that the air channel 107 is isolated from the water flow area inside the water column 202.

[0040] At the stop water flow position, both the water passage 2031 and the air passage 2032 correspond to the planar area or other blocking area of ​​the water column 202, thereby closing both the water passage and the air passage. At this time, even if the external water supply system continues to supply water, the water flow cannot enter the water channel 108 through the water pipe 201, thus stopping the shower head from flowing water.

[0041] In the clean position, the venting groove 2022 has sufficient extension length along the rotation direction of the water column 202 and can simultaneously correspond to the air vent 2032 and the water vent 2031. The opening of the venting groove 2022 faces the switching baffle 203. After the end face of the water column 202 cooperates with the switching baffle 203, the venting groove 2022 forms a relatively closed cavity, allowing the air vent 2032 and the water vent 2031 to communicate through this cavity. At the same time, the water venting groove 2021 is offset from the water vent 2031, so the normal water path remains closed. Thus, the air passage 107 can communicate with the water passage 108 through the air vent 2032, the venting groove 2022, and the water vent 2031, while water cannot enter the water passage 108 along the normal water outlet path.

[0042] During cleaning, first, rotate the water jet 202 to the cleaning position using the switching knob 204, so that the water passage 2031 is misaligned with the water channel 2021, and the air passage 2032 and water passage 2031 are both located within the corresponding range of the air channel 2022. Then, press the enclosing member 105 to reduce the volume of the chamber formed by the enclosing member 105 and the shower head body 100. Because the air inlet 103 restricts the return flow of air from the chamber to the outside, the air in the chamber is compressed and enters the air passage 107 through the air outlet 104.

[0043] Compressed air entering the air passage 107 passes sequentially through the air vent 2032, air groove 2022, water vent 2031, and water passage 108, and then enters the water outlet chamber 109, finally being discharged through the water outlet plate 106. Since residual water exists in the water passage 108, water outlet chamber 109, and the internal flow channels and chambers fluidly connected to the water outlet plate 106, the compressed air can push the residual water, causing it to move towards the water outlet plate 106 and ultimately be discharged from it, thus achieving the discharge of residual water from the relevant internal flow channels of the water outlet plate 106.

[0044] After the pressure on the enclosing member 105 is released, the enclosing member 105 recovers under the action of elastic restoring force, increasing the volume of the aforementioned chamber. At this time, the air outlet 104 restricts air from returning to the chamber through the air passage 107, while external air enters through the rotational gap between the shower head body 100 and the water outlet plate 106, and further enters the internal chamber of the enclosing member 105 through the air inlet 103. By repeating the pressing and releasing action, the compression exhaust and external air replenishment can be cyclically performed.

[0045] In one embodiment, the shower head body 100 is provided with a water collection groove and a water collection arc surface on the side connected to the air outlet 104. If water accidentally enters the chamber formed by the enclosure member 105 and the shower head body 100, the shower head can be adjusted to a position suitable for the liquid to flow towards the air outlet 104, so that the water entering the chamber flows along the water collection arc surface to the water collection groove and gathers near the air outlet 104. Since the air outlet 104 is connected to the air passage 107, and in the clean position the air passage 107 is already connected to the water passage 108 through the air vent 2032, the air groove 2022 and the water passage 2031, the water entering the chamber can enter the air passage 107 through the air outlet 104, and then pass through the air vent 2032, the air groove 2022, the water passage 2031, the water passage 108 and the water outlet chamber 109 in sequence, and finally be discharged through the water outlet plate 106. The above drainage process can be carried out naturally in the clean position without the need for other drainage operations.

[0046] In this embodiment, the air outlet 104 serves two functions simultaneously: on the one hand, it acts as an outlet structure for compressed air entering the air passage 107 when the enclosing member 105 is pressed; on the other hand, it acts as a discharge structure for water entering the air passage 107 when water accidentally enters the internal cavity of the enclosing member 105. Thus, the same air and water communication path can be used to both discharge residual water inside the water outlet pan 106 and discharge water that accidentally enters the enclosing member 105.

[0047] In the description of this application, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0048] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
