Description

Technical Field

[0001] This utility model relates to the field of shower head technology, and in particular to a shower head that removes scale and drains residual water. Background Technology

[0002] Over time, limescale will gradually accumulate in showerheads after prolonged use. This limescale can clog the water outlets, affecting the normal operation of the showerhead. Currently, showerheads on the market offer automatic descaling capabilities. These typically feature a descaling plate with several descaling needles arranged on its bottom surface. The descaling plate moves up and down using water flow, allowing the descaling needles to move back and forth synchronously within the water outlets, thus achieving automatic descaling of the showerhead's water outlets.

[0003] In existing technology, the descaling needles of the descaling needle plate will block the water outlet of the shower head after the water is turned off, which will prevent the water remaining inside the shower head from being discharged. Over time, the water will deteriorate and produce an odor, affecting the user experience and health. Utility Model Content

Detailed Implementation

[0025] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0026] refer to Figure 1-5 As shown, this utility model discloses a descaling and residual water draining shower head, including a shell 1, a water outlet cover 2, a water sealing base 3, and a descaling needle plate 4;

[0027] The outer shell 1 and the water outlet cover 2 enclose each other to form a cavity;

[0028] The water sealing seat 3 is set inside the cavity and surrounds the water outlet cover 2 to form a water passage cavity a; the water sealing seat 3 is provided with a water inlet 31, which is connected to the water passage cavity a; the water outlet cover 2 is provided with a number of water outlet holes 21 and drain holes 22.

[0029] The descaling needle plate 4 is driven by the water flow entering the water passage a and moves axially within the water passage a along the outlet hole 21. It is equipped with a descaling needle 41 opposite to the outlet hole 21 and a sealing column 42 opposite to the drain hole 22. The descaling needle 41 is movably inserted through the corresponding outlet hole 21, and the sealing column 42 is movably inserted through the corresponding drain hole 22. The opening states of the outlet hole 21 and the drain hole 22 are inconsistent. That is, when the descaling needle 41 is inserted into the outlet hole 21 (the outlet hole 21 is closed), the sealing column 42 does not seal the drain hole 22 (the drain hole 22 is open), and when the descaling needle 41 is removed from the outlet hole 21 (the outlet hole 21 is open), the sealing column 42 seals the drain hole 22 (the drain hole 22 is closed).

[0030] Based on the above solutions, refer to Figure 4-5 As shown, this utility model provides an additional water-sealing column 42 on the descaling needle plate 4, and a drain hole 22 is provided at the corresponding position of the water outlet cover 2. The opening states of the water outlet 21 and the drain hole 22 are inconsistent, so that when the descaling needle 41 performs descaling operation in the water outlet 21, the residual water in the water passage cavity a can be discharged through the drain hole 22, avoiding water retention in the water passage cavity a, thereby ensuring the hygiene of the shower head.

[0031] The following are specific embodiments of the present invention.

[0032] This utility model also includes a first spring 5 and a linkage assembly 6; the first spring 5 is disposed between the water sealing seat 3 and the descaling needle plate 4, and is used to provide elastic force so that the descaling needle plate 4 moves axially along the water outlet 21 and inserts the descaling needle 41 into the water outlet 21; the linkage assembly 6 is dynamically sealed at the connection between the water inlet 31 and the water passage a, and its end is linked with the descaling needle plate 4; when water is introduced, the water pressure drives the linkage assembly 6 to move to open the connection between the water inlet 31 and the water passage a, and links the descaling needle plate 4 to compress the first spring 5 and move axially in the water outlet 21 to disengage from the water outlet 21. At this time, refer to Figure 5 Water entering the inlet 31 flows through the aforementioned connection and is sprayed out through the outlet 21, enabling the shower head to function as a water outlet. When the shower head stops receiving water, the descaling needle plate 4 will reset under the elastic force of the first spring 5. Each descaling needle 41 inserts into the corresponding outlet 21 and descals the side wall of the outlet 21 through friction between the two. At the same time, the descaling needle plate 4 drives the linkage component 6 to reset when resetting. Thus, every time the shower head completes a water switching action, a descaling action is performed on the water outlet cover 2. This action is performed automatically when the user is using the shower head normally, without requiring any additional operation from the user. This achieves automatic descaling of the shower head, with the descaling frequency matching the shower head's usage frequency, thereby ensuring that the outlet 21 of the shower head is unobstructed and not blocked.

[0033] Furthermore, the aforementioned water-sealing seat 3 is provided with a water passage 32 extending horizontally at the water outlet end of the water inlet 31, and the side wall of the water passage 32 connects to the water passage cavity a; the linkage component 6 is dynamically and sealingly fitted inside the water passage 32; when water is introduced, the water pressure drives the linkage component 6 to move axially in the water passage 32 to open the connection between the water passage 32 and the water passage cavity a, thereby realizing the connection between the water inlet 31 and the water passage cavity a. In this embodiment, the side wall of the aforementioned water passage 32 is provided with a water passage hole 33 to connect the water passage 32 and the water passage cavity a; in the state where no water is introduced, the water passage hole 33 is sealed by the linkage component 6, and after water is introduced, the axial movement of the linkage component 6 gradually opens the water passage hole 33.

[0034] Secondly, the inlet 31 is provided with several water passages 32 at equal angles along its circumference (for example, four in this embodiment). Each water passage 32 is provided with a linkage component 6, that is, the shower head has multiple linkage components 6 at equal angles and evenly arranged, so that the descaling needle plate 4 is subjected to more balanced force in all directions, ensuring that the descaling needle plate 4 moves along the axial direction of the outlet hole 21, so that each descaling needle 41 can efficiently clean the corresponding outlet hole 21.

[0035] The aforementioned water outlet 21 is a conical hole, and the diameter of the water inlet end of the water outlet 21 is larger than the diameter of its water outlet end; the descaling needle 41 of the descaling needle plate 4 is a conical part. The conical structure of the water outlet 21 and the descaling needle 41 makes it easy for the two to separate, so as to reduce the wear on the water outlet 21 when the descaling needle 41 is separated from the water outlet 21.

[0036] Several first springs 5 ​​are arranged at equal angular intervals around the axis of the inlet 31; several guide posts 23 are provided on the side of the outlet cover 2 facing the descaling needle plate 4, and the descaling needle plate 4 is provided with movable sleeve holes 43 that are movably fitted onto the guide posts 23; a positioning post 34 is provided on the side of the sealing seat 3 facing the descaling needle plate 4, and the two ends of the first springs 5 ​​are respectively fitted onto the guide posts 23 and the positioning posts 34 to keep the position of the first springs 5 ​​fixed. By having multiple first springs 5 ​​apply force evenly to the descaling needle plate 4, it can be ensured that the descaling needle plate 4 is subjected to a balanced spring force to ensure that it does not deviate when moving.

[0037] The aforementioned water-sealing base 3 is provided with a movable hole 35 opposite to the drain hole 22. The two ends of the water-sealing column 42 protrude from the upper and lower surfaces of the descaling needle plate 4, respectively, and its upper and lower ends are dynamically sealed through the movable hole 35 and the drain hole 22, respectively. In this embodiment, the upper end of the aforementioned water-sealing column 42 and the inner wall of the drain hole 22 are respectively provided with a first sealing ring 7 and a second sealing ring 8 to achieve a dynamic sealing effect. The second sealing ring 8 is fixed to the water outlet cover 2 by a pressure ring 9.

[0038] refer to Figure 3 The diagram shows an exploded view of the linkage assembly 6. This linkage assembly 6 includes a push rod 61 that movably passes through the water passage 32, and a third sealing ring 62 fitted onto the first end of the push rod 61. The third sealing ring 62 is dynamically sealed to the side wall of the water passage 32. A protrusion 44 is formed on the surface of the descaling needle plate 4, allowing the second end of the push rod 61 to move and engage. A first guide slope 441 is provided within the protrusion 44, and the second end of the push rod 61 is provided with a second guide slope 611 that moves and engages with the first guide slope 441. Through the engagement of the first guide slope 441 and the second guide slope 611, the pressure generated by the water flow can be converted into the power of the descaling needle plate 4, or the elastic force applied to the descaling needle plate 4 by the first spring 5 can be converted into the power of the push rod 61.

[0039] Furthermore, the first end of the push rod 61 is provided with a countersunk hole 612, and the opening of the countersunk hole 612 is provided with a flared end 613. By providing the countersunk hole 612 and the flared end 613, the area on which the water flows onto the push rod 61 can be increased, thereby making it easier to push the push rod 61 to move axially.

[0040] Meanwhile, the aforementioned linkage component 6 also includes a second spring 63 and a limiting buckle 64; a limiting ring 614 is provided on the circumferential surface of the push rod 61; the water sealing seat 3 is provided with a buckle seat 36 opposite to the outlet of the water passage 32; the limiting buckle 64 is engaged in the buckle seat 36; the second end of the push rod 61 is movably inserted through the limiting buckle 64; the second spring 63 is sleeved on the push rod 61, and its two ends abut against the limiting ring 614 and the limiting buckle 64 respectively, to provide elastic force to reset the push rod 61.

[0041] This utility model also includes a water inlet assembly 10; the outer shell 1 is provided with a clearance hole 11 opposite to the water inlet 31; the water inlet assembly 10 is movably inserted through the clearance hole 11 and connected to the water inlet 31 of the water sealing seat 3. The water inlet assembly 10 is composed of accessories such as a ball head, a water-saving plate, a fixing nut, and a decorative cover, so that the overhead shower head can be connected to the water supply end (such as a shower or water pipe).

[0042] The outer shell 1 and the water outlet cover 2 are assembled by means of snap-fit ​​connection, rotation snap-fit, screw fastening and other detachable methods to facilitate disassembly, assembly and maintenance; the water outlet cover 2 and the water sealing base 3 are assembled by means of adhesive bonding, welding and other integrated connection methods to ensure sealing and prevent water leakage.
