The existing manufacturer dilutes the water quality of the high TDS by discharging the high TDS water for the first time or by a built-in water tank, and the water resources and the product space are greatly wasted in the modes, so that a new technical mode is urgently required in the market to solve the problem of high TDS of the water quality of the first time.
The volume of water treatment products occupies a large proportion of the space in cabinets, and the diversification of kitchen appliances requires that the volume of water treatment products in cabinets be smaller and smaller. The existing water treatment equipment has the defects that when parts are connected in the waterway, the number of the switching pieces is too large, various manufacturing and assembling errors increase the risk of water leakage of products, and meanwhile, the cost is increased and the waste is caused. The assembly of various parts is required, and the integration type modularization is lacking, so that the complexity of the assembly of the product is increased and the reduction of the volume of the product is limited. The existing water treatment products are not reasonably integrated and optimized among various valves, switches and other accessories, so that the space utilization of the products is unreasonable, and the cost of the products is not optimized enough. Because of various demands and practical applications of water treatment, waterways of the required water purifying equipment are more and more complex, and structural requirements are more and more simple.
The water purifiers on the market also have application reversing valves, but the structures are different, wherein the water purifiers are subjected to single-way water reversing, for example, the application number is as follows: 201510492419.8, name of invention: the water path switching valve and the water purifier with the water path steering valve are used for switching the water in a single path, and the steering valve core is rotated to switch the raw water flow into the water purifier or directly discharge the raw water.
