Description

Technical Field

[0001] The utility model relates to the field of bathroom fittings, in particular to a shower head. Background Art

[0002] The shower head is used for spraying water flow to achieve flushing and cleaning. For different usage requirements, most of them have a gear shifting function. By rotating the water outlet dial, the water outlet dial is docked with different water outlets in the shower head body to realize the switching of different water outlet modes. At present, for the shower head with shiftable gears, its water outlet dial is directly rotatably fixed on the shower head body through screws. The shower head body is generally injection molded. At the same time, in order to meet the adaptation with the water outlet dial, a water channel for switching or an additional component with a water channel needs to be designed. Moreover, when designing the shower head body, the conditions for demolding and core pulling need to be met, and the cooling shrinkage problem caused by different wall thicknesses of the shower head body and the subsequent surface treatment (chromium plating) problem also need to be considered, resulting in a relatively complex design structure and process, and a troublesome assembly. Content of the Utility Model

[0003] Based on the above problems, the purpose of the utility model is to provide a shower head with a simple structure and process and convenient for assembly.

[0004] For the above problems, the following technical solution is provided: A shower head includes a handle and a shell connected to each other.

[0015] Advantages of the present utility model:

[0016] 1. The water outlet adjustment assembly is placed into the housing as a module, and then the water outlet adjustment assembly is fixed by a fixing ring, realizing simple and rapid installation; compared with the prior art where the water outlet dial needs to be fixed to the shower body by screws, the modular installation can effectively simplify the structures of the housing and the handle (without considering the mutual influence between the structure and the core pulling), and at the same time is convenient for replacing materials and production methods, achieving the purpose of simplifying the production process, reducing production costs, and improving the assembly convenience;

[0017] 2. Compared with the production by injection molding, which requires designing a special injection mold with a long design time and high design cost, and the cooling time during injection is also likely to slow down the production rhythm; in this solution, the housing and the fixing ring can be formed only by stamping and stretching, having the advantages of fast production rhythm and strong and durable structure;

[0018] 3. In the later stage of production by injection molding, processes such as surface treatment (chromium plating) are also required, and it is also easy to be damaged due to bumping and scratching during use; both the housing and the fixing ring are made of stainless steel, eliminating the high surface treatment cost, and the surface can be directly polished, effectively avoiding damage caused by bumping and scratching while meeting the strength requirements;

[0019] 4. The handle and the housing are preferably fixed in the form of a thread and with a sealant to achieve anti-loosening while meeting the sealing requirements; the circumferential constraint groove and the end of the handle invading into the inner cavity of the housing are adapted to provide circumferential constraint for the main body of the water outlet adjustment assembly, so as to prevent the main body from rotating together when the water outlet dial rotates to adjust the water outlet mode;

[0020] 5. The main body is preferably injection-molded, which is convenient for core pulling and demolding. The reason for producing the main body separately by the injection process is that its structure is simple and the demolding is convenient, so the requirements for the mold are also relatively low;

[0021] 6. The handle, the housing, and the fixing ring are made of stainless steel, which has the advantages of beauty, good corrosion resistance, and high structural strength. Brief Description of the Drawings

One end of the housing 20 corresponding to the opening 21 is provided with a butt joint thread 22. It further includes a fixing ring 40, which is screwed with the butt joint thread 22 and is provided with an inner shoulder 41 for fixing the main body 31 in the opening 21 to prevent it from coming out.

[0031] In the above structure, the water outlet adjusting assembly 30 is placed into the housing 20 as a module, and then the water outlet adjusting assembly 30 is fixed by the fixing ring 40, realizing simple and rapid installation. Compared with the prior art where the water outlet dial 32 needs to be fixed to the shower head body by screws, the modular installation can effectively simplify the structures of the housing 20 and the handle 10 (without considering the mutual influence of the structure and the core pulling), and at the same time is convenient for replacing materials and production methods, achieving the purpose of simplifying the production process, reducing production costs, and improving the assembly convenience.

[0032] In this embodiment, both the housing 20 and the fixing ring 40 are formed by stamping and stretching metal plates.

[0033] In the above structure, compared with the production by injection molding which requires designing a special injection mold with a long design time and high design cost, and the cooling time during injection is also likely to slow down the production rhythm; in this solution, the housing 20 and the fixing ring 40 can be formed only by stamping and stretching, having the advantages of fast production rhythm and strong and durable structure.

[0034] In this embodiment, both the housing 20 and the fixing ring 40 are made of stainless steel.

[0035] In the above structure, in the later stage of production by injection molding, surface treatment (chromium plating) and other processes are also required, and it is also easy to be damaged due to bumps, scratches, etc. during use; both the housing 20 and the fixing ring 40 are made of stainless steel, eliminating the high surface treatment cost, and their surfaces can be directly polished, effectively avoiding damage caused by bumps and scratches on the premise of meeting the strength requirements.

[0036] In this embodiment, the butt joint thread 22 is an external thread, and the fixing ring 40 is provided with an internal thread 42 screwed with the butt joint thread 22.
