Description

Technical Field

[0001] The invention belongs to the technical field of faucets, in particular to a faucet. Background Art

[0002] The faucets in the prior art are simple in structure, and there is no spring at the reversing rod, so they cannot be automatically reset and need to be manually reset, which makes the operation cumbersome. Since the signs of the hot and cold water ends of most faucets are not obvious, and the water temperature cannot be known by visual inspection, scalding incidents often occur when operating the faucet to discharge water, because some hot water flows over the valve and out of the faucet outlet, causing scalding accidents; however, since this rotatable faucet can rotate left and right, but cannot be extended forward and backward, the flushing range is limited and cannot cover every corner of the sink. It is very inconvenient for users to wash large or complex objects to be washed.

[0003] In addition, the current water purification filter element generally contains KDF and activated carbon. The filter element is to purify the polluted water to the state required for production and life, that is, to make the water reach a certain degree of cleanliness. According to the different uses of the filtered water, there are many types of water purification filter elements used, such as activated carbon filter elements, PP filter elements, ceramic filter elements, resin filter elements, titanium rod filter elements, nanofiltration membrane filter elements, hollow fiber ultrafiltration membrane filter elements, RO reverse osmosis membrane filter elements, etc. The existing filter element is large in size, which will inevitably make the equipment using the filter element larger accordingly. This will not only bring inconvenience to transportation, but also increase the manufacturing cost of the enterprise, and then increase the user's use cost. Summary of the invention
