Description

Technical Field

[0002] The switching mechanism is an essential component in the switching shower head, and there are many design schemes. At present, the switching mechanisms on the market basically adopt a single water inlet and multiple water outlets. Such a structure is relatively simple, and the molding of the water outlet is also simple. However, such a one-to-many water outlet method is prone to water channel mixing, especially for some water outlets equipped with filters, beauty essences or bath products. The mixing of water channels can easily cause the mixing of water outlets between different water channels, which corresponds to the problem of filtered water being contaminated, or the clean water channel being contaminated by water mixed with beauty essence. It can be seen that the existing switching structure needs to be improved. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a relatively independent switching mechanism for water channels, which can avoid the mixing of water channels.
