Description

Technical Field

[0001] This application relates to the field of bathroom technology, and more specifically, to a self-cleaning shower head. Background Technology

[0002] A shower head is a common shower device that disperses the water flow to improve the showering effect.

[0003] After prolonged use, limescale and impurities in the water can accumulate and clog the showerhead's nozzles, affecting its water flow performance and even rendering it unusable. Therefore, how to clean the limescale and impurities from the nozzles is a technical problem that urgently needs to be solved. Utility Model Content

[0004] This application provides a self-cleaning shower head, which can automatically clean the shower head and maintain good water output performance.

[0005] Some embodiments of this application provide a self-cleaning shower head, which includes a shower head body, a cleaning component, and an elastic component. The shower head body has a water outlet and a water inlet. The cleaning component is movably disposed inside the shower head body. The elastic component is disposed inside the shower head body and is used to provide an elastic force to the cleaning component, so that the cleaning component is inserted into the water outlet. The shower head body has a first flow channel, one end of which is connected to the water inlet, and the other end is disposed corresponding to the cleaning component, so that the water flow in the first flow channel pushes the cleaning component out of the water outlet.

[0006] In the above solution, the cleaning component is movably disposed inside the shower head body, having a first position inserted into the water outlet and a second position withdrawn from the water outlet. By setting an elastic element and a second flow channel, the cleaning component can switch between the first and second positions under the action of the elastic element and water pressure, thereby achieving automatic cleaning of the water outlet and ensuring that the shower head maintains good water output performance.

[0007] According to some embodiments of this application, the shower head body also has a second flow channel inside, which is connected to the first flow channel, and one end of the second flow channel is connected to the water inlet hole and the other end is connected to the water outlet hole.

[0008] In the above scheme, on the one hand, when the cleaning component is in the first position, the water flow inside the second flow channel merges into the first flow channel to jointly push the cleaning component so that it exits the water outlet, thereby opening the water outlet; on the other hand, by setting the second flow channel, the water flow rate of the water outlet can be guaranteed to meet the requirements to a certain extent.

[0009] According to some embodiments of this application, the shower head body includes a housing, a water outlet, and a water rotating plate. The housing and the water outlet cover each other. A water inlet is formed on the side of the housing opposite to the water outlet, and a water outlet is formed on the side of the water outlet opposite to the housing. The water rotating plate is disposed between the housing and the water outlet, and the water rotating plate forms a first flow channel and a second flow channel inside the shower head body.

[0010] In the above solution, by setting a water-turning plate between the housing and the water outlet, the flow direction of the water inside the shower head body can be changed, so that part of the water flow can pass through the first flow channel and act on the cleaning component, thereby pushing the cleaning component to move out of the water outlet, so that the water flow can be discharged from the water outlet, and another part of the water flow can pass through the second flow channel and be discharged from the water outlet.

[0011] According to some embodiments of this application, the water-turning plate and the water outlet together form a chamber that communicates with the water inlet. The wall of the water-turning plate has a first through hole and a second through hole. Along the movement direction of the cleaning component, the projection of the cleaning component falling on the water-turning plate covers the first through hole, and the second through hole communicates with the water outlet.

[0012] In the above scheme, the water-rotating plate has a simple structure and is easy to manufacture. By setting a first through hole and a second through hole on the wall at different positions on the water-rotating plate, a first flow channel and a second flow channel are formed inside the shower head body, realizing the normal water output and automatic cleaning function of the shower head.

[0013] According to some embodiments of this application, along the direction in which the housing and the water outlet cover each other, the water-turning plate includes a first part and a second part that are connected to each other. Along the circumference of the water-turning plate, the second part protrudes from the first part, and the second part includes a top wall and a side wall. One end of the top wall is connected to the first part, the other end of the top wall is connected to the side wall, and the end of the side wall opposite to the top wall is connected to the water outlet.

[0014] In the above scheme, the water-turning plate includes a first part and a second part that are connected to each other. Along the circumference of the water-turning plate, the second part protrudes from the first part, so that the second part forms a top wall and a side wall that are perpendicular to each other. Thus, a first through hole and a second through hole can be respectively set on the top wall and the side wall to form a first flow channel and a second flow channel, so as to realize the normal water output of the shower head and the automatic cleaning function.

[0015] According to some embodiments of this application, the cleaning component is a needle plate, which includes a plate body, a protrusion, and a needle body. The plate body is disposed on the outer periphery of the protrusion, and a guide hole is formed on the side of the protrusion opposite to the water outlet. A first part passes through the guide hole, and the needle body is disposed on the side of the plate body facing the water outlet for insertion into the water outlet. A first through hole is formed in the top wall, and a second through hole is formed in the side wall.

[0016] In the above solution, the cleaning component is a needle plate, which has a simple structure and is easy to manufacture. The needle plate includes a plate body, a protrusion, and a needle body. The first part has a guide hole through the protrusion so that the top wall can correspond to the protrusion. When water flows out from the first through hole, it acts on the side of the protrusion facing the top wall, thereby pushing the entire needle plate to move away from the water outlet, so that the needle body retracts from the water outlet and water can be sprayed out from the water outlet. When the shower stops supplying water, the needle plate returns to its original position under the action of the elastic element, so that the needle body inserts into the water outlet for cleaning.

[0017] According to some embodiments of this application, a guide portion is formed inside the housing, the guide portion is arranged around the outer periphery of the first portion, and a guide hole is formed on the side of the protrusion opposite to the water outlet, the guide portion passing through the guide hole.

[0018] In the above solution, by setting a guide part, on the one hand, the water inlet hole can be connected to the internal chamber of the water rotating plate, and on the other hand, the movement of the cleaning component can be guided, so that the cleaning component moves stably in the preset direction and realizes the self-cleaning function of the shower head.

[0019] According to some embodiments of this application, the elastic element is sleeved on the outer periphery of the guide portion. Along the direction in which the housing and the water outlet cover each other, one end of the elastic element abuts against the side of the housing facing the water outlet, and the other end of the elastic element abuts against the side of the protrusion facing the housing.

[0020] In the above solution, by sleeved on the outer periphery of the guide, the elastic element can provide a directionally stable elastic force to the cleaning element, so that after each shower stops supplying water, the cleaning element can be reset and inserted into the water outlet of the shower head, thereby achieving self-cleaning of the shower head.

[0021] According to some embodiments of this application, a first seal is provided between the first part and the guide part.

[0022] According to some embodiments of this application, a second seal is provided between the water outlet and the housing.

[0023] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0035] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0036] This embodiment provides a self-cleaning shower head 100; please refer to [link / reference]. Figures 1-3 , Figure 1 This is an exploded perspective view of the self-cleaning shower head 100 in some embodiments of this application. Figure 2 This is an internal schematic diagram of the self-cleaning shower head 100 in one embodiment of this application when no water is flowing. Figure 3 This is an internal schematic diagram of the self-cleaning shower head 100 when water is being discharged in one embodiment of this application.

[0037] The self-cleaning shower head 100 includes a shower head body 10, a cleaning element 20, and an elastic element 30. The shower head body 10 has a water outlet 11 and a water inlet 12. The cleaning element 20 is movably disposed inside the shower head body 10. The elastic element 30 is disposed inside the shower head body 10 and is used to provide elastic force to the cleaning element 20 so that the cleaning element 20 is inserted into the water outlet 11. The shower head body 10 has a first flow channel inside, one end of which is connected to the water inlet 12, and the other end is disposed corresponding to the cleaning element 20, so that the water flow in the first flow channel pushes the cleaning element 20 out of the water outlet 11.

[0038] In some embodiments, the shower body 10 is a water outlet structure of a self-cleaning shower head 100. The shower body 10 is connected to an external pipeline through a water inlet hole 12, so that water from the external pipeline can enter the shower body 10 and finally be discharged from the water outlet hole 11.

[0039] Optionally, the water outlet 11 is located on one side of the shower head body 10, and the water inlet 12 is located on the opposite side of the shower head body 10. For example, the central axis of the water outlet 11 and the central axis of the water inlet 12 are flush with each other. Optionally, the central axis of the water outlet 11 and the central axis of the water inlet 12 intersect.

[0040] The cleaning component 20 is a structural member movably disposed inside the shower head body 10, allowing it to switch between a first position and a second position. When the cleaning component 20 is in the first position, it can be inserted into the water outlet 11 to clean scale and impurities from the outlet 11. When the cleaning component 20 is in the second position, it can be withdrawn from the water outlet 11, allowing water to flow normally from the outlet 11.

[0041] Optionally, the cleaning component 20 includes a needle body 23, which may have a sharp structure. For example, the needle body 23 may be a descaling needle, which can remove scale or other impurities from the water outlet 11 as it is inserted and withdrawn from the outlet 11, thus ensuring the cleanliness of the outlet 11.

[0042] The elastic element 30 is a structural component disposed inside the shower head body 10. The elastic element 30 is used to provide elastic force to the shower head body 10 so that the shower head body 10 is in the first position.

[0043] The first flow channel is located inside the shower head body 10. Water enters the shower head body 10 through the inlet hole 12 and flows through the first flow channel. The water in the first flow channel can flow to the cleaning element 20 and push the cleaning element 20 to move, overcoming the elastic force of the elastic element 30, so that the cleaning element 20 exits the outlet hole 11, and the outlet hole 11 is unobstructed, thus allowing water to flow out. In some embodiments, by providing a water flow structure inside the shower head body 10, the direction of water flow inside the shower head body 10 is changed to push the cleaning element 20. Exemplarily, the cleaning element 20 and the shower head body 10 together form the first flow channel, and when water enters the first flow channel, the cleaning element 20 can be pushed to move as the water pressure increases.

[0044] In the above solution, the cleaning component 20 is movably disposed inside the shower head body 10, so as to have a first position inserted into the water outlet 11 and a second position withdrawn from the water outlet 11. By setting the elastic component 30 and the second flow channel, the cleaning component 20 can switch between the first position and the second position under the action of the elastic component 30 and water pressure, thereby realizing automatic cleaning of the water outlet 11 and keeping the shower head with good water output performance.

[0045] According to some embodiments of this application, the shower head body 10 also has a second flow channel inside, which is connected to the first flow channel, and one end of the second flow channel is connected to the water inlet hole 12, and the other end is connected to the water outlet hole 11.

[0046] In some embodiments, see Figure 3 Arrow A points to the water flow in the first flow channel, and arrow B points to the water flow in the second flow channel.

[0047] For example, please see Figure 3The cleaning component 20 is in the first position and is inserted into the water outlet 11. The water outlet 11 is in the closed state. Water flows into the shower body 10 through the water inlet 12. After passing through the first flow channel and the second flow channel, they work together to push the cleaning component 20 out of the water outlet 11, thereby opening the water outlet 11. After the water outlet 11 is opened, water can be discharged from the water outlet 11.

[0048] In the above scheme, on the one hand, when the cleaning component 20 is in the first position, the water flow inside the second flow channel merges into the first flow channel to jointly push the cleaning component 20 so that the cleaning component 20 exits the water outlet 11, thereby opening the water outlet; on the other hand, by setting the second flow channel, the water flow rate of the water outlet 11 can be guaranteed to meet the requirements to a certain extent.

[0049] According to some embodiments of this application, the shower body 10 includes a housing 13, a water outlet 14, and a water rotating plate 15. The housing 13 and the water outlet 14 cover each other. A water inlet hole 12 is formed on the side of the housing 13 away from the water outlet 14, and a water outlet hole 11 is formed on the side of the water outlet 14 away from the housing 13. The water rotating plate 15 is disposed between the housing 13 and the water outlet 14, and the water rotating plate 15 forms a first flow channel and a second flow channel inside the shower body 10.

[0050] Please combine Figures 1-3 The shower head body 10 includes a housing 13, a water outlet 14, and a water rotating plate 15. The housing 13 and the water outlet 14 constitute the main parts of the shower head body 10. In some embodiments, the outer peripheral surface of the water outlet 14 is connected to the inner peripheral surface of the housing 13, and the two can be integrated by threaded engagement, snap-fit ​​engagement, or other connection relationships. A pipe is formed on the side of the housing 13 opposite to the water outlet 14, and the pipe surrounds and forms a water inlet 12. A plurality of water outlet holes 11 are formed on the side of the water outlet 14 opposite to the housing 13.

[0051] The water-spinning plate 15 is disposed between the housing 13 and the water outlet 14, and the water-spinning plate 15 is located between the water inlet 12 and the water outlet 11, forming a first flow channel and a second flow channel. The water flow entering the shower body 10 through the water inlet 12 enters the water-spinning plate 15 and is divided. Part of it enters the first flow channel to flow towards the cleaning component 20, thereby driving the cleaning component 20 to move, and the other part flows towards the water outlet 11 and can be sprayed directly from the water outlet 11.

[0052] In the above solution, by setting a water-turning plate 15 between the housing 13 and the water outlet 14, the flow direction of the water inside the shower body 10 can be changed, so that a part of the water flow can act on the cleaning component 20 through the first flow channel, thereby pushing the cleaning component 20 to move out of the water outlet 11, so that the water flow can be discharged from the water outlet 11, and another part of the water flow can be discharged from the water outlet 11 through the second flow channel.

[0053] According to some embodiments of this application, the water-turning plate 15 and the water outlet 14 together form a chamber that communicates with the water inlet 12. The wall of the water-turning plate 15 has a first through hole 150 and a second through hole 151. Along the movement direction of the cleaning member 20, the projection of the cleaning member 20 falling on the water-turning plate 15 covers the first through hole 150, and the second through hole 151 communicates with the water outlet 11.

[0054] Please see Figure 2 and Figure 3 A chamber is formed between the water plate 15 and the water outlet 14. The chamber is connected to the water inlet 12. The water flow entering through the water inlet 12 can be contained in the chamber. Part of the water flow in the chamber flows to the first through hole 150 to push the cleaning member 20 so that the cleaning member 20 moves to exit the water outlet 11. The other part flows to the second through hole 151, flows to the unobstructed water outlet 11, and is sprayed out from the water outlet 11.

[0055] In the above scheme, the water-turning plate 15 has a simple structure and is easy to manufacture. By setting the first through hole 150 and the second through hole 151 on the wall parts at different positions of the water-turning plate 15, the first flow channel and the second flow channel are formed inside the shower body 10, so as to realize the normal water output and automatic cleaning function of the shower head.

[0056] According to some embodiments of this application, along the direction in which the housing 13 and the water outlet 14 overlap, the water-turning plate 15 includes a first portion 152 and a second portion 153 that are interconnected. Along the circumferential direction of the water-turning plate 15, the second portion 153 protrudes from the first portion 152. The second portion 153 includes a top wall 1530 and a side wall 1531. One end of the top wall 1530 is connected to the first portion 152, and the other end of the top wall 1530 is connected to the side wall 1531. The end of the side wall 1531 opposite to the top wall 1530 is connected to the water outlet 14.

[0057] In some embodiments, there are multiple first through holes 150, and the multiple first through holes 150 are spaced apart around the axis of the top wall 1530.

[0058] In some embodiments, there are multiple second through holes 151, and the multiple second through holes 151 are arranged at circumferential intervals along the sidewall 1531.

[0059] Please see Figure 2 and Figure 3The outer diameter of the first part 152 is smaller than the outer diameter of the second part 153. One end of the first part 152 is connected to the water inlet 12, and the other end is connected to the interior of the second part 153. The second part 153 includes a top wall 1530 and a side wall 1531. The top wall 1530 is disposed around the outer periphery of the first part 152, and the side wall 1531 is disposed around the edge of the top wall 1530. The end of the side wall 1531 opposite to the top wall 1530 is connected to the water outlet 14. In some embodiments, the side wall 1531 is welded to the water outlet 14.

[0060] In the above scheme, the water-turning plate 15 includes a first part 152 and a second part 153 that are connected to each other. Along the circumference of the water-turning plate 15, the second part 153 protrudes from the first part 152, so that the second part 153 forms a top wall 1530 and a side wall 1531 that are perpendicular to each other. Thus, a first through hole 150 and a second through hole 151 can be respectively provided on the top wall 1530 and the side wall 1531 to form a first flow channel and a second flow channel, so as to realize the normal water output of the shower head and the automatic cleaning function.

[0061] According to some embodiments of this application, the cleaning component 20 is a needle plate, which includes a plate body 21, a protrusion 22, and a needle body 23. The plate body 21 is disposed on the outer periphery of the protrusion 22, and a guide hole is formed on the side of the protrusion 22 opposite to the water outlet 14. A first portion 152 passes through the guide hole. The needle body 23 is disposed on the side of the plate body 21 facing the water outlet 14 and is used to insert into the water outlet 11. A first through hole 150 is formed in the top wall 1530, and a second through hole 151 is formed in the side wall 1531.

[0062] In some embodiments, the cleaning component 20 is a needle plate, which includes a plate body 21, a protrusion 22, and needles 23. The number of needles 23 is the same as the number of water outlet holes 11. Multiple needles 23 are disposed on the side of the plate body 21 facing the water outlet 14 so as to be able to be inserted into the corresponding water outlet hole 11. In some embodiments, when the cleaning component 20 is in a first position, the needles 23 are inserted into the water outlet hole 11 and can extend beyond the water outlet hole 11.

[0063] The protrusion 22 is provided corresponding to the second part 153. The inner periphery of the protrusion 22 is in clearance fit with or in contact with the outer periphery of the second part 153, and the top of the protrusion 22 is disposed opposite to the top wall 1530 of the second part 153. A guide hole is formed on the top of the protrusion 22 and is located on the outer periphery of the first part 152.

[0064] The phrase “the first through hole 150 is formed on the top wall 1530 and the second through hole 151 is formed on the side wall 1531” can be understood as follows: a portion of the water flow in the chamber flows out through the first through hole 150 to push the protrusion 22 to move the entire needle plate toward the housing, thereby causing the needle body 23 to exit the water outlet 11. The other portion of the water flow in the chamber flows out through the second through hole 151 to the water outlet 11 and is ejected from the water outlet 11.

[0065] In the above scheme, the cleaning component 20 is a needle plate, which has a simple structure and is easy to manufacture. The needle plate includes a plate body 21, a protrusion 22, and a needle body 23. The first part 152 passes through the guide hole of the protrusion 22 so that the top wall 1530 can be set corresponding to the protrusion 22. When water flows out from the first through hole 150, it can act on the side of the protrusion 22 facing the top wall 1530, thereby pushing the entire needle plate to move in a direction away from the water outlet 14, so that the needle body 23 exits the water outlet 11, allowing water to spray out from the water outlet 11. When the shower stops supplying water, the needle plate is reset under the action of the elastic member 30, so that the needle body 23 is inserted into the water outlet 11 for cleaning.

[0066] According to some embodiments of this application, a guide portion 130 is formed inside the housing, the guide portion 130 is arranged around the outer periphery of the first portion 152, and a guide hole is formed on the side of the protrusion 22 opposite to the water outlet 14, and the guide portion 130 passes through the guide hole.

[0067] The guide portion 130 is a flange structure formed inside the housing and protruding towards the outlet 14. The guide portion 130 is arranged around the outer periphery of the first portion 152, that is, the outer periphery of the first portion 152 is connected to the inner periphery of the guide portion 130. The protrusion 22 of the needle plate is located on the outer periphery of the guide portion 130, and the guide portion 130 passes through the guide hole of the protrusion 22 so that the entire needle plate can move relative to the protrusion 22.

[0068] In the above solution, by setting the guide part 130, on the one hand, the water inlet hole 12 can be connected to the internal chamber of the water rotating plate 15, and on the other hand, the cleaning part 20 can be guided to move stably along the preset direction, so as to realize the self-cleaning function of the shower head.

[0069] According to some embodiments of this application, the elastic member 30 is sleeved on the outer periphery of the guide portion 130. Along the direction in which the housing 13 and the water outlet 14 cover each other, one end of the elastic member 30 abuts against the side of the housing 13 facing the water outlet 14, and the other end of the elastic member 30 abuts against the side of the protrusion 22 facing the housing 13.

[0070] Please see Figure 2In some embodiments, the elastic element 30 is a spring, which is sleeved on the outer periphery of the guide portion 130. One end of the spring abuts against the housing 13 and the other end abuts against the protrusion 22 to provide an elastic force to the needle plate to move toward the nozzle 14.

[0071] In the above solution, by sleeved on the outer periphery of the guide portion 130, the elastic element 30 can provide a directionally stable elastic force to the cleaning element 20, so that after each shower stops supplying water, the cleaning element 20 can be reset and inserted into the water outlet hole 11 of the shower head, thereby achieving self-cleaning of the shower head.

[0072] According to some embodiments of this application, a first seal 40 is provided between the first portion 152 and the guide portion 130. In some embodiments, the first seal 40 is a sealing ring, a sealing groove is formed on the outer periphery of the first portion 152, the first seal 40 is assembled in the sealing groove, and is pressed against each other by the first portion 152 and the guide portion 130.

[0073] According to some embodiments of this application, a second sealing element 50 is provided between the water outlet 14 and the housing 13. In some embodiments, the second sealing element 50 is a sealing ring, and a sealing groove is formed on the outer periphery of the water outlet 14. The second sealing element 50 is assembled in the sealing groove and is pressed against the water outlet 14 and the housing 13.

[0074] Some embodiments of this application provide the working process of the self-cleaning shower head 100 described above: Please refer to Figure 2 and Figure 3 Water flows into the shower body 10 through the inlet hole 12, entering the chamber formed by the rotating plate 15 and the outlet nozzle 14. A portion of the water flows upward through the first through hole 150, creating an impact force. This impact force acts on the needle plate, pushing it to compress the elastic element 30 and move upward, causing the needle body 23 to detach from the outlet hole 11. It should be noted that this portion of the water flow may include the water flowing through the first and second flow channels.

[0075] Another portion of the water flows through the second through hole 151 into the outlet hole 11, enabling the shower head to spray water normally. When the water flow stops, the needle plate returns to its original position under the action of elastic force, and the needle body 23 inserts into the outlet hole 11, pushing out the dirt in the outlet hole 11, thus achieving self-cleaning of the shower head.

[0076] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
