Description

Technical Field

[0001] This utility model relates to the field of shower head technology, and in particular to a descaling shower head. Background Technology

[0002] Currently, descaling showerheads on the market generally consist of a showerhead body, a water outlet cover, and a moving part. The water outlet cover has a water outlet, and the moving part has a pin. The moving part is movably positioned within the showerhead body between the initial position and the descaling position. In the initial position, the pin retracts inward from the water outlet; in the descaling position, the pin extends outward from the water outlet. This reciprocating motion of the pin removes scale from the water outlet, achieving the descaling effect.

[0003] In existing technologies, to effectively remove scale from the water outlet, the ejector pin is typically designed to extend a predetermined length beyond the outlet when in the descaling position. However, ejector pins are generally thin and have limited strength. If the shower head is accidentally dropped or someone touches and wipes the shower head's spray cover while the ejector pin is in the descaling position, the ejector pin can easily break due to contact with the portion extending beyond the outlet.

[0004] Therefore, it is necessary to provide a descaling shower head that can effectively remove scale from the nozzle while also protecting it. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes a descaling shower head that can effectively remove scale from the nozzle while also protecting it.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A descaling shower head includes a shower head body, a water outlet cover, and a movable component. The water outlet cover has a water outlet, and the movable component has a pin. The movable component is movably disposed within the shower head body between an initial position and a descaling position. In the initial position, the pin retracts inward from the water outlet; in the descaling position, the pin extends outward from the water outlet. The shower head also includes a pin protection structure disposed on the water outlet side of the water outlet. The pin protection structure has an open receiving cavity communicating with the water outlet, and in the descaling position, the pin is at least partially received within the receiving cavity.

[0008] In a preferred embodiment, when in the descaling position, the outer end of the ejector pin is located in the receiving cavity.

[0009] In a preferred embodiment, the maximum size of the opening of the receiving cavity is less than or equal to 10 mm, and the depth of the receiving cavity is greater than or equal to 0.5 mm.

[0010] In a preferred embodiment, the ejector pin protection structure is a recess on the water outlet cover. The recess is formed by the inward concavity of the surface of the water outlet cover, and the cavity of the recess forms the receiving cavity. The water outlet is located on the bottom wall of the recess, and the bottom surface of the recess forms the water outlet end face of the water outlet.

[0011] In a preferred embodiment, when in the descaling position, the outer end of the ejector pin is located within the recess and does not extend beyond the surface of the water outlet cover.

[0012] In a preferred embodiment, when the descaling position is reached, the outer end of the ejector pin extends beyond the surface of the water outlet cover by no more than 2 mm.

[0013] In a preferred embodiment, the water outlet is located in the center of the recess, and the recess surrounds the water outlet.

[0014] In a preferred embodiment, the ejector pin protection structure is a mesh-shaped protective cover, which is fixedly placed on the outside of the water outlet cover, and the gaps between the meshes of the protective cover form the receiving cavity.

[0015] In a preferred embodiment, each of the receiving cavities corresponds to one of the water outlets and one of the ejector pins.

[0016] In a preferred embodiment, the water outlet cover is rotatably mounted on the shower head body, and the water outlet cover is linked to the movable component. When the water outlet cover rotates in the first position and the second position, it can drive the movable component to move between the initial position and the descaling position.

[0017] In a preferred embodiment, the water outlet cover is further provided with a decorative pit, which is formed by the indentation of the surface of the water outlet cover.

[0018] This utility model has the following beneficial effects:

[0019] This invention features a pin protection structure on the water outlet side of the showerhead cover. This structure has an open receiving cavity communicating with the water outlet. In the descaling position, at least part of the pin is contained within this cavity. This ensures that, firstly, during normal shower operation, the open cavity does not obstruct water flow, allowing water to flow out freely. Secondly, during descaling, the cavity protects at least a portion of the pin extending beyond the water outlet, preventing contact with external objects and effectively preventing breakage due to the showerhead falling or human contact when the pin is extended beyond its predetermined length. This invention has a simple structure and effectively protects the pin while allowing it to extend beyond the water outlet for effective descaling, with a significant protective effect.

[0036] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0037] First Embodiment

[0038] Please see Figures 1 to 7 A preferred embodiment of this utility model discloses a descaling shower head, comprising a shower head body 1, a water outlet cover 2, and a movable component 3. The water outlet cover 2 is provided with a water outlet 21, and the movable component 3 is provided with a pin 311. The movable component 3 is movably disposed within the shower head body 1 between an initial position and a descaling position. In the initial position, the pin 311 retracts inward from the water outlet 21; in the descaling position, the pin 311 extends outward from the water outlet 21. The reciprocating motion of the pin 311 removes the scale from the water outlet 21, achieving the descaling effect.

[0039] The descaling showerhead also includes a pin protection structure 4 located on the water outlet side of the outlet 21. The pin protection structure 4 has an open receiving cavity 41 communicating with the outlet 21. In the descaling position, the pin 311 is at least partially received in the receiving cavity 41. In this way, on the one hand, when the showerhead is in normal water flow, the open cavity 411 of the receiving cavity will not block the water flow from the outlet 21, and the water flow from the outlet 21 can flow out through the open cavity 411 of the receiving cavity; on the other hand, in the descaling state of the showerhead, the receiving cavity 41 can collect and protect at least a part of the pin 311 that extends out of the outlet 21, preventing it from being touched by foreign objects, thus playing a protective role. This can effectively prevent the pin 311 from easily breaking due to the showerhead falling or being touched and wiped by hand when it extends a predetermined length out of the outlet 21. This utility model has a simple structure and can protect the ejector pin 311 while allowing the ejector pin 311 to extend out of the outlet 21 by a predetermined length to effectively remove scale from the outlet 21. The protection effect is obvious.

[0040] The maximum size of the opening 411 of the receiving cavity 41 is preferably less than or equal to 10 mm, and the depth of the receiving cavity 41 is preferably greater than or equal to 0.5 mm. This size design generally prevents most adults' fingers from entering the receiving cavity 41 completely, thereby preventing fingers from touching the pin inside the receiving cavity 41. The cross-sectional shape of the receiving cavity 41 can be circular, square, or other irregular shapes. In this embodiment, it is specifically circular, and its diameter is preferably 2.5 mm-3 mm, and its depth is 0.5 mm-1 mm. This preferred size range can effectively prevent the pin inside the receiving cavity 41 from being broken by foreign objects, providing better protection.

[0041] In this embodiment, the ejector pin protection structure 4 is directly disposed on the water outlet cover 2. Specifically, the ejector pin protection structure 4 is a recess 22 disposed on the water outlet cover 2. The recess 22 is formed by the indentation of the surface 23 of the water outlet cover. The cavity of the recess 22 forms a receiving cavity 41. The water outlet 21 is disposed on the bottom wall of the recess 22, and the bottom surface 221 of the recess forms the water outlet end face of the water outlet 21. By using the recess 22 formed by the indentation of the surface 23 of the water outlet cover as the ejector pin protection structure 4, the structure is very simple.

[0042] In this embodiment, when in the descaling position, the outer end of the ejector pin 311 extends beyond the surface 23 of the water outlet cover, and the length of the extended portion does not exceed 2mm. Due to the protective function of the receiving cavity 41, even if part of the ejector pin 311 protrudes from the surface 23 of the water outlet cover, it is not easily broken by external objects.

[0043] In this embodiment, the water outlet 21 is located in the center of the recess 22, and the recess 22 surrounds the water outlet 21. See also Figure 7In this embodiment, the water outlet 21 is funnel-shaped, and its diameter gradually decreases from the water inlet end to the water outlet end. Each receiving cavity 41 corresponds to a water outlet 21 and a pin 311.

[0044] In this embodiment, the water outlet cover 2 is also provided with decorative pits 24, which are formed by the indentation of the surface 23 of the water outlet cover. One or more decorative pits 24 can be provided between two adjacent pits 22 for decoration, and the decorative pits 24 serve a decorative function.

[0045] In this embodiment, the water outlet cover 2 is rotatably mounted on the shower head body 1. The water outlet cover 2 is equipped with a knob 25, which drives the water outlet cover 2 to rotate. The water outlet cover 2 has multiple spaced water outlets 21. The water outlet cover 2 is linked to a movable component 3, which includes a movable plate 31. The movable plate 31 has multiple pins 311 corresponding to each water outlet 21. When the water outlet cover 2 rotates in the first and second positions, it can drive the movable plate 31 to move between the initial position and the descaling position. The rotation of the water outlet cover 2 driving the movement of the movable plate 31 can directly adopt existing known structures. Alternatively, the movement of the movable component 3 between the initial position and the descaling position can also be achieved under hydraulic drive, using existing hydraulic drive structures, which will not be described in detail here.

[0046] Second Embodiment

[0047] Please see Figure 8 and Figure 9 Another preferred embodiment of the present invention provides a descaling shower head, which differs from the first embodiment in that: in the first embodiment, when in the descaling position, the outer end of the pin 311 extends beyond the surface 23 of the water outlet cover by a certain length; while in this embodiment, when in the descaling position, the outer end of the pin 311 is located in the receiving cavity 41, that is, the outer end of the pin 311 is located in the recess 22, and the outer end of the pin 311 does not extend beyond the surface 23 of the water outlet cover. In other words, when in the descaling position, the part of the pin 311 that extends out of the water outlet 21 is entirely contained in the receiving cavity 41, thereby receiving more complete and better protection from the receiving cavity 41.

[0048] In the first and second embodiments described above, the ejector pin protection structure 4 is directly mounted on the water outlet cover 2. However, in other embodiments, the ejector pin protection structure 4 may not be directly mounted on the water outlet cover 2. For example, the ejector pin protection structure 4 can be replaced with a mesh-like protective cover (not shown). The protective cover is fixedly mounted on the outside of the water outlet cover 2, and the gaps between the meshes of the protective cover form the receiving cavity 41. This also provides protection for the ejected ejector pin 311. Preferably, the protective cover can be detachably snap-fitted to the water outlet cover 2.
