Abstract
Description
Technical Field
[0001] This utility model relates to the field of shower head technology, and in particular to a shower head with a pressure relief valve. Background Technology
[0002] In daily life, most showerheads used for showering have relatively small nozzles to ensure strong water spray. Over time, limescale or impurities in the water can further reduce the nozzle size, even causing blockages. This shrinking nozzle size leads to increased water pressure inside the showerhead; or, due to other unforeseen circumstances, the water pressure may suddenly rise. Excessive water pressure can cause the showerhead to burst, potentially causing injury to the user. Therefore, showerheads designed to prevent excessive internal water pressure have been developed on the market.
[0003] For example, patent CN104971834A discloses an explosion-proof shower head that can prevent the shower head from bursting due to smaller or clogged spray nozzles or abnormally high water pressure. The technical solution adopted in this invention is to install an explosion-proof valve in the shower head. The explosion-proof valve can automatically open or close according to changes in water pressure within the shower head, thereby regulating the water pressure.
[0004] The problem with the above technology is that the explosion-proof valve is located inside the shower head. When the explosion-proof valve is damaged, the user needs to disassemble the shower head to replace the explosion-proof valve. Disassembly and assembly are difficult and can easily damage the shower head. Therefore, professional maintenance personnel are required to replace it, resulting in high labor costs.
[0005] To address this issue, a shower head with a pressure relief valve is proposed to solve the aforementioned technical problems. Utility Model Content
[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a shower head with a pressure relief valve, which can adjust the water pressure inside the shower head and facilitate the disassembly and assembly of the pressure relief valve.
[0007] The technical solution adopted by this utility model to solve the problem is: a shower head with a pressure relief valve, including a shower head body, the shower head body is provided with a water inlet and a water outlet, the shower head body is provided with a water passage connecting the water inlet and the water outlet, the shower head body is also provided with a mounting hole connecting the water passage, and a pressure relief valve is provided at the mounting hole, the pressure relief valve being located on the outside of the shower head body.
[0008] As a further improvement to the above technical solution, the mounting hole is provided with an internal thread, the end of the pressure relief valve is provided with an external thread, and the pressure relief valve is screwed into the mounting hole.
[0009] As a further improvement to the above technical solution, the pressure relief valve is provided with an installation cavity and a pressure relief hole, the pressure relief hole is connected to the installation cavity and the water passage, and a plug that seals the pressure relief hole is elastically connected in the installation cavity.
[0010] As a further improvement to the above technical solution, the mounting cavity is provided with an internal thread and also includes an inner nut. The inner nut is screwed into the mounting cavity, and the inner nut is provided with a water passage hole communicating with the outside and the mounting cavity. A spring is provided between the inner nut and the plug.
[0011] As a further improvement to the above technical solution, the outer surface of the pressure relief valve is provided with toothed patterns.
[0012] The beneficial effects of this utility model are: water can enter from the inlet and flow through the water channel, and finally the water can flow out from the outlet. When the outlet is blocked, the water pressure in the water channel will increase, and the water can flow out through the pressure relief valve, preventing the pressure inside the shower body from becoming too high and thus damaging the shower body. Since the pressure relief valve is installed on the outside of the shower body, when the pressure relief valve is damaged, the user can replace the pressure relief valve himself, which is convenient for disassembly and assembly and saves labor costs.

[0025] Reference Figures 1 to 6 A shower head with a pressure relief valve includes a shower body 1, on which a water inlet 11 and a water outlet 12 are provided. A water passage 13 is provided inside the shower head, connecting the water inlet 11 and the water outlet 12. A mounting hole 14 is also provided on the shower body 1, connecting the water passage 13. A pressure relief valve 2 is provided at the mounting hole 14, and the pressure relief valve 2 is located on the outside of the shower body 1.
[0026] During use, water can enter from the inlet 11 and flow through the water channel 13, and finally flow out from the outlet 12. When the outlet 12 is blocked, the water pressure in the water channel 13 will increase, and the water can flow out through the pressure relief valve 2 to prevent the pressure inside the shower body 1 from becoming too high and thus damaging the shower body 1. Since the pressure relief valve 2 is installed on the outside of the shower body 1, when the pressure relief valve 2 is damaged, the user can replace the pressure relief valve 2 by himself, which is convenient for disassembly and assembly and can save labor costs.
[0027] In a preferred embodiment, in order to facilitate the installation of the pressure relief valve 2, an internal thread is provided at the mounting hole 14, and an external thread is provided at the end of the pressure relief valve 2, and the pressure relief valve 2 is screwed into the mounting hole 14.
[0028] In a preferred embodiment, the pressure relief valve 2 is provided with an installation cavity 21 and a pressure relief hole 22. The pressure relief hole 22 is connected to the installation cavity 21 and the water passage 13. A plug 23 is elastically connected in the installation cavity 21 to seal the pressure relief hole 22.
[0029] When the pressure in the water passage 13 is greater than a certain value, the water in the water passage 13 can pass through the pressure relief hole 22 and push up the plug 23, so that the mounting cavity 21 and the pressure relief hole 22 are connected, and finally the water can be discharged outward from the mounting cavity 21.
[0030] In a preferred embodiment, the mounting cavity 21 is provided with an internal thread and also includes an inner nut 24, which is screwed into the mounting cavity 21. The inner nut 24 is provided with a water passage hole 25 that communicates with the outside and the mounting cavity 21. A spring 26 is provided between the inner nut 24 and the plug 23.
[0031] In a preferred embodiment, in order to facilitate the installation of the pressure relief valve 2, the outer surface of the pressure relief valve 2 is provided with teeth 27. The teeth 27 can increase the friction force, making it easier for the user to turn the pressure relief valve 2.
[0032] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
