Water inlet-outlet valve and cleaning device provided with same

Abstract

The invention relates to a water inlet-outlet valve and a cleaning device provided with the same. The valve comprises an upper cover, an upper valve core, a lower valve core, a casing and a motor; theupper cover is provided with a first port, a second port, a third a port and a fourth port; the upper valve core is provided with a first hole communicating with the first port, a second hole communicating with the second port, a third hole communicating with the third port, and a fourth hole communicating with the fourth port; the lower valve core is provided with a water guiding groove for connecting or disconnecting the first hole and the second hole or the third hole and the fourth hole; the lower valve core is rotationally connected with the motor; the water guiding groove connects or disconnects the first hole, and the second hole connects or disconnects a water supply water channel, or the water guide groove connects or disconnects the third hole, and the fourth hole connects or disconnects a water drainage channel. The valve body has two functions of the water inlet channel and the water drainage channel, and is more practical; through the water inlet-outlet functions of the cleaning device, the number of the valve is reduced, the cost is reduced, and time and effort are saved.

Description

technical field [0001] The invention relates to a valve body and a cleaning device, in particular to a two-in-one valve body with water inlet and outlet and a cleaning device with the valve body. Background technique [0002] Existing valve bodies have the function of adding water or draining separately, and the water inlet valve body can only be installed at the place where the water enters, and the drain valve body can be installed at the place where the water is drained; when two functions of water inlet and drain are required on the same device , it is necessary to install valve bodies with different functions to achieve the purpose of adding water or draining water separately; therefore, installing multiple valve bodies on the same device is not only complicated in structure, time-consuming and laborious in assembly and maintenance, but also relatively high in cost. [0003] In view of this, the inventor of the present invention aimed at many shortcomings and inconvenie...

Problems solved by technology

[0002] Existing valve bodies have the function of adding water or draining separately, and the water inlet valve body can only be installed at the place where the water enters, and the drain valve body can be installed at the place where the water is drained; when two functions of water inlet and drain are required on the same device , it is necessary to install valve bodies with different functions to achieve the purpose of adding water or draining water separately; therefore, installing multiple valve bodies on the same device is not only complicated in structure, time-consuming and laborious in assembly and maintenance, but also relatively high in cost

[0003] In view of this, the inventor aimed at the many defects and inconveniences caused by the imperfect structural design of the above-mentioned valve body and cleaning device, and deeply conceived, and actively researched and improved the trial production and developed and designed this case
