Specifically, the first fluid outlet 130 is distributed on a different side of the valve body 110 than the first fluid inlet 120, and the axis of the first fluid outlet 130 is parallel to the axis of the first fluid inlet 120. By the parallel distribution of the first fluid inlet 120 and the second fluid outlet 140 on the same side, the layout of the second fluid outlet 140 and the first fluid inlet 120 is consistent with the layout of the outlet and the inlet of the general water purifying electromagnetic valve, and the universality of the product is improved.

In some embodiments, the valve cover 150 and the outer partition 210 may be ultrasonically welded, and the valve body 110 and the outer partition 210 may be ultrasonically welded. Specifically, the side of the valve cover 150 where the sealing gap 1505 is provided is ultrasonically welded to the outer spacer 210, and the support 1105 of the valve body 110 is ultrasonically welded to the outer spacer 210. The strength and the tightness of the product are further improved through ultrasonic welding.

The application at least one embodiment also provides a water purifying device, which comprises the shunt according to any embodiment of the application, and further has all technical effects brought by the technical scheme of the embodiment. It should be noted that the water purifying device includes, but is not limited to, a water purifier, and a direct drinking machine.

While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the respective embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions falling within the scope of the claims.
