Description

Technical Field

[0001] The utility model relates to the technical field of bath equipment accessories, in particular to a shower head water joint. Background Art

[0002] With the continuous improvement of people's living standards, the forms of shower heads are becoming more and more diverse, and the overhead shower heads are becoming more and more popular. For example, an overhead shower head with a large water outlet angle adjustment range disclosed in the publication number CN218148694U includes a mounting plate and a mounting box with an open bottom. A plurality of water inlet connecting pipes are connected to the bottom of the mounting plate. An inlet water adapter is provided at the bottom of the water inlet connecting pipe. A plurality of water inlet connectors are provided at the top of the mounting box. A connecting ball head is screwed on the top of the water inlet connector. A water passing channel is provided inside the connecting ball head. A connecting screw sleeve is sleeved outside the connecting ball head. An upper waterproof rubber ring and a lower waterproof rubber ring are respectively sleeved inside the connecting screw sleeve. An overhead shower head is installed inside the mounting box. A plurality of water inlet joints are provided at the top of the overhead shower head. The water inlet joints are connected to the water inlet connectors through water inlet hoses. The structure of the utility model is simple, the structure is stable, the installation is convenient, the shower angle can be adjusted within a large range, the use is convenient, the multi-directional shower requirements of people are met, the use fun of users is improved, and the consumer experience is good. However, the angle adjustment of the above solution is realized through the connecting ball head, and the locking of the installation box angle after adjustment is realized through the friction force of the upper waterproof rubber ring and the lower waterproof rubber ring in contact with the connecting ball head, so as to realize the angle adjustment of the shower head within a certain range. However, when the shower head is full of water, the entire movable shower head part is heavy, and the main function of the waterproof rubber ring is to prevent water leakage. Using it as the force-bearing locking structure of the shower head is likely to cause the deformation of the waterproof rubber ring, resulting in insufficient locking force, and it is also likely to cause water leakage at the waterproof rubber ring. The waterproof rubber ring that is frequently subjected to irregular extrusion forces is prone to fatigue aging, resulting in low reliability and short service life of the entire shower device. Therefore, it is necessary to invent a shower head water joint with high reliability and long service life, which can facilitate the connection between the overhead shower head and the water supply and realize the angle adjustment of the shower head within a certain range.
