Description
Technical Field
The invention belongs to the technical field of water purification auxiliary equipment, and particularly relates to a tap water purification conversion valve.
Background
At present, people pay more and more attention to safety and health along with the improvement of living standard. Water is used as a life source and occupies an important position in life of people, and as people pay more and more attention to water quality, the household water purifier is more and more commonly used.
The existing household water purifier in the market mainly comprises a kitchen lower water purifier and an upper water purifier, wherein the kitchen lower water purifier is arranged below a kitchen operation table board, and the kitchen lower water purifier has the advantages that the layout of the kitchen table board is not influenced, the kitchen table board is convenient to clean, and a water inlet pipe and a waste water pipe are convenient to arrange below the table board; the water purifier has the disadvantages that an additional water purifying faucet needs to be installed on the opening of the table top, the water purifier is suitable for a new house for installing the water purifier during decoration, the installation of the water purifying faucet of the under-kitchen water purifier is troublesome for a family which is finished with decoration, and particularly, the under-kitchen water purifier cannot be installed when the table top of a kitchen of some families does not have redundant space for installing the water purifying faucet. The water purifier on the table is integrally arranged on a table top or a kitchen table top, and a water purifying faucet is directly arranged on the water purifier to discharge water, so that the water purifier is more suitable for most families which are additionally provided with the water purifier after finishing decoration, but a plurality of pipelines such as a water inlet pipe connected with an indoor water supply pipeline and a waste water pipe of the water purifier on the table top are exposed and need to bypass, the pipelines are complex, and the integral cleanness and tidiness of the kitchen are influenced.
Therefore, some manufacturers have developed the water diversion valve body directly mounted on the existing tap water faucet, and directly use the tap water faucet head as the water inlet and outlet of the water purifier, especially the bench water purifier, and select whether the tap water supplied by the tap water faucet is supplied directly or supplied after passing through the water purifier through the water diversion valve body, so that the pipelines can be greatly reduced, and the water purifier faucet is not required to be added, so that the water inlet and outlet structure of the water purifier is simpler. However, the existing water distribution valve body adopts the electromagnetic valve, so that the cost is high, the failure rate is high, and the popularization is restricted.
