Inlet electric valve for water purifier

Abstract

The invention discloses an inlet electric valve for a water purifier. The valve comprises a bottom case, a socket, a motor, a valve body and a travel switch; the socket and a relative port of the bottom case are connected in a butt joint mode to form a case of the electric valve, the motor is fixed in the bottom case, the output shaft of the motor is connected with the driving end of a ceramic valve spool of the valve body, the valve body is fixed in the port of the socket, the ceramic valve spool of the valve body is located in a valve spool cavity in the socket, a seal ring at the top end of the ceramic valve spool is in close contact with the side wall of the valve spool cavity, and therefore a seal structure between a water inlet and a water outlet is formed; an instruction which makes the motor stop to work is sent through the travel switch by the motor. The inlet electric valve for the water purifier can solve the technical problems that the actuation time is long, the volume is large, and the manufacturing cost is high, which exist in a traditional electric ball valve, and the blockage occurs because the valve is prone to the influence of impurity, the flow quantity is small, there is the directivity of liquid delivery, at the same time, a coil is prone to heating after long time operation, and therefore the service life of an electromagnetic valve is influenced, which exist in a traditional electromagnetic valve, and the like.

Description

technical field [0001] The invention relates to a water purifier technology, in particular to an accessory for the water purifier. Background technique [0002] Electric control switch valves used in water purifiers or water supply pipelines generally include solenoid valves and electric ball valves. The electric ball valve has a large friction force when opening and closing, requires a high speed ratio driven by the motor, takes a long time to operate, has a large volume and high production cost. Because the solenoid valve is designed with a small hole, it is easily blocked by impurities, the flow rate is also small, and it has the directionality of liquid transportation. At the same time, the coil is prone to heat when it works for a long time, which affects the working life of the solenoid valve. In actual use, in order to prevent the blockage of the valve body due to impurities, a filter element device should be connected to the pipeline between the solenoid valves. Wh...

Problems solved by technology

[0003] The purpose of the present invention is to provide a water inlet electric valve for water purifiers to solve the problem that the traditional electric ball valve has a long action time, large volume and high production cost, and the traditional electromagnetic valve is easily affected by impurities and causes blockage. The flow rate is also very small, and it has the directionality of liquid transportation. At the same time, the coil is prone to heat when it works for a long time, which affects the working life of the solenoid valve and other technical problems.
