Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1 to 4, a water inlet valve includes a valve body 1, a water inlet passage 10 and a filtering assembly 20 for filtering water flow of the water inlet passage 10 are disposed on the valve body 1, a non-return unit 30 is further disposed on the valve body 1, in a normal state, the non-return unit 30 opens the water inlet passage 10, and when the filtering assembly 20 is detached from the valve body 1, the non-return unit 30 closes the water inlet passage 10.

In this embodiment, the valve body 1 is provided with the water through hole 11, the non-return unit 30 is provided with a sealing portion capable of sealing or opening the water through hole 11, in a normal state, the sealing portion is far away from the water through hole 11 and then opens the water inlet passage 10, and when the filter assembly 20 is detached from the valve body 1, the sealing portion moves in a direction close to the water through hole 11 and seals the water through hole 11 and then closes the water inlet passage 10.

In this embodiment, an elastic member 40 is further disposed between the valve body 1 and the water stopping unit 30, and the elastic member 40 provides an elastic force for driving the sealing portion to move toward the water through hole 11. Specifically, the elastic member 40 is a return spring.

In this embodiment, the sealing portion is disposed at one end of the non-return unit 30, the other end of the non-return unit 30 is disposed with a guiding portion which is matched with the water inlet channel 10 in a guiding manner, specifically, the sealing portion includes a sealing sheet 31 and a sealing gasket 32 disposed at one side of the sealing sheet 31 in a limiting manner, and the water passing hole 11 is closed or opened through the sealing gasket 32.

In this embodiment, the guide portion includes a front wedge buckle 33 disposed at the other end of the non-return unit 30, and further includes a guide block 34 engaged with the front wedge buckle 33, and the guide block 34 slides on the water inlet channel 10 in a guiding manner.

In this embodiment, the valve body 1 is further provided with a filter cavity 50 and a water outlet channel 60, the water inlet channel 10 is communicated with the water outlet channel 60 through the filter cavity 50, the filter assembly 20 is installed in the filter cavity 50 from the top of the valve body 1, specifically, a water stop unit 70 is arranged between the filter cavity 50 and the water outlet channel, the water stop unit 70 adopts a pressure differential type water stop mechanism in the prior art, and the structure and principle of the pressure differential type water stop mechanism please refer to the prior art, which is not described herein again.
