Description

Technical Field

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

[0002] Currently, most showerheads on the market experience clogged water outlets after prolonged use. As usage time increases, impurities and minerals in the water gradually deposit and accumulate in the showerhead's outlets. Especially in areas with hard water, large amounts of calcium and magnesium ions in the water, after repeated evaporation and sedimentation, form limescale that adheres tightly to the inner walls of the outlets, causing blockages.

[0003] Currently, users mainly use manual cleaning methods, such as using sharp objects like needles and toothpicks to unclog the blocked water outlets one by one and remove the impurities inside the holes. However, this method is cumbersome and the cleaning effect is not ideal. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A self-cleaning shower head includes a housing with a fixed base and a water outlet base. The water outlet base is rotatably connected to the housing and has several water outlet holes. A needle plate is movably disposed within the water outlet base, and the needle plate has cleaning needles corresponding to the water outlet holes. The shower head also includes a drive assembly for driving the needle plate. The drive assembly includes a connecting post disposed on the side of the needle plate facing the fixed base. The connecting post extends through the water outlet base and is slidably connected to it. The side of the fixed base facing the water outlet base has a concave-convex surface, including a concave portion and a convex portion. The connecting post contacts the concave-convex surface. An elastic element is disposed between the side of the needle plate facing the water outlet holes and the water outlet base. When the water outlet base rotates, causing the connecting post to move from the concave portion to the convex portion of the concave-convex surface, it pushes the needle plate towards the water outlet holes. When the connecting post moves from the convex portion to the concave portion of the concave-convex surface, the elastic element pushes the needle plate back to its original position.

[0006] The present invention is further configured such that: the elastic element is a spring, a positioning groove is provided on the needle plate, one end of the spring is disposed in the positioning groove, a positioning post is provided on the water outlet seat, and the spring is sleeved on the outside of the positioning post.

[0007] The present invention is further configured such that: the end of the connecting column facing the fixed seat is provided with a rounded corner, and the connection between the concave part and the convex part of the concave-convex surface is an arc transition.

[0008] The present invention is further configured such that: the water outlet base includes a water outlet cover and a switching plate, the water outlet cover and the switching plate form a water outlet cavity, the needle plate is movably disposed in the water outlet cavity, the water outlet hole is opened on the water outlet cover, the switching plate is provided with a through hole, the connecting column is slidably connected to the through hole, and passes through the water outlet base through the through hole.

[0009] The present invention is further configured such that a Y-shaped ring is provided between the inner wall of the through hole and the peripheral side wall of the connecting column.

[0010] The present invention is further configured such that: a stepped surface is provided on the peripheral side wall of the switching disk, and a plurality of buckles that cooperate with the stepped surface are provided on the fixing seat, and the fixing seat is fixed inside the housing.

[0011] The present invention is further configured such that: a water inlet seat is provided on the housing, and water flows into the housing from the water inlet seat, and after passing through the fixed seat, it is sprayed out from the water outlet hole of the water outlet seat.

[0013] The present invention is further configured such that the filter pad is interference-fitted with the water inlet of the water inlet seat.

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] 1. When the water outlet seat rotates, the connecting column moves between the concave and convex parts of the concave-convex surface, and works with the elastic element for resetting to drive the cleaning needle to move or reset towards the water outlet hole. This automatically unclogs the water outlet hole, effectively removing impurities and scale deposited inside the hole. This solves the problem of manual cleaning required for existing shower heads, realizes the self-cleaning function, greatly improves the convenience of cleaning the water outlet hole, and enhances the cleaning effect.

[0016] 2. The rounded corners at the ends of the connecting column and the arc transition design of the concave and convex surfaces make the connecting column move more smoothly on the concave and convex surfaces, reducing friction and wear between the two, reducing the resistance when the water outlet seat rotates, and making it more convenient for users to operate.

[0017] 3. The detachable filter screen at the water inlet of the water inlet seat filters the water entering the shower head, intercepting impurities and reducing the possibility of impurities entering the water outlet and causing blockage. The detachable design allows users to clean or replace the filter screen regularly, ensuring the long-term filtration effect and reducing clogging problems at the source. Combined with the self-cleaning function, it further improves the lifespan of the shower head and the cleanliness of the water flow. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0026] A self-cleaning shower head, such as Figures 1 to 3 As shown, it includes a housing 1, a fixed seat 2 and a water outlet seat are provided on the housing 1, the water outlet seat is rotatably connected to the housing 1, a plurality of water outlet holes 5 are provided on the water outlet seat, a needle plate 6 is movably arranged inside the water outlet seat, and a cleaning needle 19 corresponding to the water outlet hole 5 is provided on the side of the needle plate 6 facing the water outlet hole 5. It also includes a drive assembly for driving the movement of the needle plate 6.

[0027] Specifically, the drive assembly includes a connecting post 7 disposed on the side of the needle plate 6 facing the fixed base 2. The connecting post 7 passes through the water outlet base and is slidably connected to it. The fixed base 2 is provided with a concave-convex surface 8 on the side facing the water outlet base. The concave-convex surface 8 includes a concave part 801 and a convex part 802. The connecting post 7 contacts the concave-convex surface 8. An elastic element is disposed between the side of the needle plate 6 facing the water outlet 5 and the water outlet base. When the water outlet base rotates and the connecting post 7 moves from the concave part 801 to the convex part 802 of the concave-convex surface 8, it pushes the needle plate 6 to move towards the water outlet 5. When the connecting post 7 moves from the convex part 802 to the concave part 801 of the concave-convex surface 8, the elastic element pushes the needle plate 6 to reset.

[0028] The concave-convex surface 8 includes three connected sets of concave portions 801 and convex portions 802, forming a circle. The convex portions 802 protrude outward relative to the concave portions 801, creating a step difference. Each time the water outlet seat rotates 120°, it switches the water spray level. The needle plate 6 moves on the concave-convex surface 8 via the connecting column 7. As it floats up and down, the cleaning needle 19 penetrates into the water outlet hole 5 to achieve self-cleaning.

[0029] In this embodiment, the needle plate 6 is provided with three connecting posts 7. The three connecting posts 7 are arranged at equal intervals along the circumference of the needle plate 6. The three connecting posts 7 correspond to three sets of concave and convex parts 802. In the initial state, the connecting posts 7 are located in the concave part 801.

[0030] In this embodiment, the elastic element is a spring 9. When the connecting post 7 moves from the concave part 801 to the convex part 802, the needle plate 6 moves forward, and the spring 9 is compressed. When the connecting post 7 moves from the convex part 802 to the concave part 801, the spring 9 rebounds and pushes the needle plate 6 backward to achieve a reset. A positioning groove 10 is provided on the needle plate 6, and one end of the spring 9 is set in the positioning groove 10. A positioning post 11 is provided on the water outlet seat. The part of the spring 9 protruding from the positioning groove 10 is sleeved on the outside of the positioning post 11 to realize the installation and guidance of the spring 9 and prevent the spring 9 from being bent when it is compressed. Specifically, three springs 9 are provided, and the three springs 9 are arranged equidistantly along the circumference of the needle plate 6. The positioning groove 10 and the positioning post 11 are also provided in three corresponding positions.

[0031] In this embodiment, the end of the connecting column 7 facing the fixed base 2 is provided with a rounded corner, and the connection between the concave part 801 and the convex part 802 of the concave-convex surface 8 is an arc transition. This makes the connecting column 7 move more smoothly on the concave-convex surface 8, reduces friction and wear between the two, reduces the resistance when the water outlet seat rotates, and makes it more convenient for users to operate.

[0032] like Figure 3 and Figure 4 As shown, the water outlet base includes a water outlet cover 3 and a switching plate 4. The water outlet cover 3 and the switching plate 4 are fixedly connected and form a water outlet cavity. The needle plate 6 is movably disposed in the water outlet cavity, and a water distribution plate 20 is also disposed in the water outlet cavity. The water outlet hole 5 is opened on the water outlet cover 3, and a through hole is opened on the switching plate 4. The connecting column 7 is slidably connected to the through hole and passes through the water outlet base through the through hole. The connecting column 7 and the through hole play a guiding role, and the needle plate 6 can only move back and forth along the direction of the connecting column 7.

[0033] A Y-ring 12 is provided between the inner wall of the through hole and the peripheral wall of the connecting post 7. The Y-ring 12 is fixed at the through hole, and the connecting post 7 slides relative to the Y-ring 12. The Y-ring 12 is pressed against the peripheral wall of the connecting post 7 to achieve a seal and prevent water from flowing back into the housing 1.

[0034] The side wall of the switching plate 4 is provided with a stepped surface 13. The fixing seat 2 is provided with several buckles 14 that cooperate with the stepped surface 13. The fixing seat 2 is fixed inside the housing 1. The water outlet seat is installed by engaging with the stepped surface 13 through the buckles 14. The buckles 14 can rotate relative to the stepped surface 13, and the water outlet seat can rotate 360° to switch gears.

[0035] like Figure 1 and Figure 5 As shown, a water inlet seat 15 is also provided on the housing 1. A handle 18 is installed on the outside of the water inlet seat 15 on the housing 1. The handle 18 is threadedly connected to the water inlet seat 15. Water flows in from the handle 18, enters the housing 1 from the water inlet seat 15, and flows through the fixed seat 2 before being sprayed out from the water outlet hole 5 of the water outlet seat.

[0036] The bottom of the water inlet base 15 has a water inlet, and a filter screen 16 is detachably connected to the water inlet. The filter screen 16 is easy to clean and can be reused. Water flows through the filter screen 16 and then flows to the water outlet cover 3. After a period of use, first remove the handle 18, remove the filter screen 16 to clean the impurities filtered on it, and then reinstall it.

[0037] In this embodiment, the filter pad 16 is made of flexible material. The filter pad 16 is interference-fitted with the water inlet of the water inlet seat 15, and the peripheral sidewalls of the filter pad 16 are engaged by friction, thereby achieving a detachable connection. Furthermore, the inner wall of the water inlet seat 15 is provided with a stepped surface 17. When the filter pad 16 is installed, it fits against the stepped surface 17, which serves as a limiting force.

[0038] The working process of this utility model is as follows:

[0039] When switching water spray levels, the user rotates the water outlet cover 3, and the needle plate 6 located in the water outlet seat rotates synchronously. The connecting column 7 moves along the concave and convex surfaces 8. When the connecting column 7 moves from the concave part 801 to the convex part 802, it pushes the needle plate 6 forward. The cleaning needle 19 on the needle plate 6 penetrates into the water outlet 5 to achieve self-cleaning. When the connecting column 7 passes the convex part 802 and moves back to the concave part 801, the spring 9 rebounds and pushes the needle plate 6 to move backward to reset. Each time the water spray is switched, a self-cleaning is completed. After the shower head has been used for a period of time, the handle 18 can be removed and the filter screen 16 can be removed for cleaning.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.

[0041] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
