Description

Technical Field

[0001] The utility model belongs to the technical field of shower heads, and particularly refers to an anti - flushing and scale - proof constant - temperature faucet. Background Technique

[0002] At present, in order to prevent impurities, dirt, etc. in tap water from entering the faucet and causing blockage of the constant - temperature valve core (if the constant - temperature valve core is blocked, the constant temperature will become unstable, sometimes cold and sometimes hot), a filter screen is often installed at the water inlet of the constant - temperature shower faucet on the market.

[0003] For example, a water - purifying and skin - beautifying composite shower faucet device disclosed in a Chinese patent with the publication number CN213839683U includes a water - mixing seat body, a water - mixing switch valve, a filter element assembly, and a water - distribution switching valve. The filter element assembly is embedded in the filter cavity. A C - shaped card slot is opened at the left end of the water - mixing seat body, and the C - shaped card slot can be used to place a shower head or a shower. The filter element assembly is a filter element for filtering bacteria, impurities, and residual chlorine, and the filter element assembly is used to filter the mixed water.

[0004] According to the water quality or the increase in the usage time, the filter element is prone to blockage, and users are forced to manually remove the filter element for cleaning or replacement, which is not convenient to use; at the same time, the intelligent level of the constant - temperature faucets on the market is low, lacking numerical display feedback of the outlet water temperature. When using, users need to first use their skin to test the water temperature and then adjust the temperature according to their needs. This method has a risk of scalding users and is not safe enough.
