Description

Technical Field

[0001] The utility model relates to an electric water circulation switch device, in particular to a waterway switch valve. Background Art

[0002] The existing small-scale electromagnetic water circuit switch valves of the same type all have a blind hole sleeve fixedly inserted in the axial direction of the valve body. The interior of the sleeve is the moving core hole. The sleeve is used for water and electricity separation / isolation. The moving shaft core is inserted into the moving core hole. The outer end of the moving shaft core is directly fixedly connected to the silicone plug. The water flow parts are fixedly sealed and connected to the front end face of the electromagnetic water circuit switch valve through a screw assembly and a silicone sealing ring. The expansion and contraction of the moving shaft core is controlled by the electromagnetic field of the electromagnetic water circuit switch valve. The silicone plug is used to block and open the water inlet. After water enters the water flow cavity, it will penetrate into the gap of the moving shaft core. There is no problem using the new product in the short term, but after long-term use, some water scale will slowly adhere to the inner wall of the moving core hole or the outer wall of the moving shaft core, and after a long time, there will be more; if it is used frequently, the expansion and contraction of the moving shaft core will rub against the inner wall of the moving core hole and it will not adhere; if the electromagnetic water circuit switch valve has been out of service for a period of time, the internal water will decrease, the scale will thicken and become mucus or have some viscosity, and stick tightly to the moving shaft core, the scale may even dry and solidify, and the next time the electromagnetic water circuit switch valve is started, the moving shaft core will not move at all, and the switching function cannot be realized, and it is broken.

[0003] Furthermore, some users install it in beverage machines to control the circulation of beverages. Most beverage liquids contain sugar, additives, ingredients, etc., and liquid scale is more likely to adhere to the inner wall of the moving core hole or the outer wall of the moving shaft core, which is not conducive to the expansion and contraction of the moving shaft core, is more likely to stick to the wall, and is unhygienic.

[0004] Furthermore, some users install it in an intelligent cooking health machine to control the circulation of the nutrient solution. Most of the nutrient solutions are made by boiling Chinese medicinal materials. The liquid has a certain concentration. It is easier for liquid scale to adhere to the inner wall of the moving core hole or the outer wall of the moving shaft core, which is not conducive to the expansion and contraction of the moving shaft core, and is easier to stick to the wall, which is also unhygienic.
