In a preferred embodiment of the present invention, the filter screen is provided with threads at the periphery thereof, and the upper duct inner wall of the through hole is provided with a threaded hole.
In a preferred embodiment of the present invention, the upper portion of the thread of the filter screen is provided with a mounting groove.
In a preferred embodiment of the present invention, a check valve seat is disposed in the conduit below the through hole.
In a preferred embodiment of the present invention, the upper end of the check valve forms a second sealing surface, and when the second sealing surface is attached to the first sealing surface, the check valve seals the through hole.
In a preferred embodiment of the present invention, the length of the second position-limiting pillar is greater than the length of the through hole, and the second position-limiting pillar passes through the through hole and abuts against the first position-limiting pillar.
In a preferred embodiment of the present invention, the through hole is disposed at an upper end portion of the guide tube.
Compared with the background technology, the technical scheme has the following advantages:
in the scheme, a one-way valve is added below the filtering plug; under the normal working state, the one-way valve does not work, and the normal work of the water inlet valve is not influenced; when the water inlet valve is not closed, the filter screen is detached, the one-way valve acts to seal the water passing channel and prevent water flow, and therefore the filter screen is detached safely and conveniently. This scheme utilization water pressure forms inhalant canal's switching control, and the impact force of effectively avoiding water pressure to cause will make the filter screen pop out and spout the water column at the dismantlement in-process, and its simple structure, factor of safety are higher, the dismouting is cheap, excellent in use effect.

Detailed Description
Referring to fig. 1 to 7, a safe and convenient filter screen 3 detaching structure of the present embodiment is disposed in a water inlet channel 1 of a water inlet valve of a water tank, wherein the water inlet channel 1 includes a conduit, and the conduit protrudes inward in a radial direction to form a through hole 12 having a diameter smaller than that of the conduit. The through hole 12 of the embodiment is a narrowed section arranged at the upper end part of the guide pipe, and a first sealing surface 13 is formed at the joint of the through hole 12 and the guide pipe;
the filter screen 3 is sleeved in the guide pipe above the through hole 12, and the lower end part of the filter screen 3 is provided with a first limiting column 24; referring to fig. 5, the filter screen 3 of the present embodiment is a bolt-type filter screen, the filter screen 3 is sequentially provided with a filter screen portion, an Oring groove 21, a peripheral thread 22 and a cylindrical filter hole 23 from top to bottom, and the first limiting column 24 is disposed in the filter hole 23 at the lower portion of the bolt. The screw thread 22 is arranged on the periphery of the filter screen 3, the inner wall of the conduit above the through hole 12 is provided with a threaded hole 11, and the filter screen 3 is screwed into the threaded hole 11 to be fixed. To ensure good sealing performance, the Oring slot 21 is provided above the thread 22 of the filter screen 3.
Referring to fig. 7, a check valve 3 is sleeved in the conduit below the through hole 12, a second limiting post 31 is disposed on an upper end surface of the check valve 3, and the first limiting post 24 abuts against the second limiting post 31. The guide pipe below the through hole 12 is internally provided with a one-way valve limiting seat 4, the one-way valve limiting seat 4 of the embodiment is a section of sleeve pipe in the guide pipe, and the distance from the limiting seat 4 to the through hole 12 is greater than the height of the one-way valve 3 and less than the height from the bottom of the one-way valve 3 to the top of the second limiting column 31. The upper end face of the non-return valve 3 forms a second sealing surface 32, and when the second sealing surface 32 is attached to the first sealing surface 13, the non-return valve 3 seals the through hole 12. The length of the second limiting column 31 is greater than that of the through hole 12, and the second limiting column 31 penetrates through the through hole 12 and abuts against the first limiting column 24.
The normal operating condition of this embodiment: when the water inlet valve is connected with a water source, the one-way valve 3 is impacted by water flow to move upwards until the second limiting column 31 of the one-way valve 3 abuts against the first limiting column 24 of the filter screen 3. The whole water flow forms a passage, and the water inlet valve works normally.
When the filter screen 3 needs to be cleaned: the filter screen 3 is screwed out upwards continuously, the one-way valve 3 moves upwards together with the filter screen 3 under the action of water flow, and the first limiting column 24 and the second limiting column 31 are still in a propping state until the second sealing surface 32 of the one-way valve 3 is attached to the first sealing surface 13 of the guide pipe. The filter screen 3 is continuously screwed out upwards, the first limit column 24 is separated from the second limit column 31, but the water flow cannot continuously flow due to the action of the one-way valve 3, and the water inlet valve is in a water stop state until the filter screen 3 is completely disassembled.
After the filter screen 3 is cleaned, the filter screen is screwed into the guide pipe until the first limiting column 24 of the filter screen 3 touches the second limiting column 31 of the one-way valve 3, and then the one-way valve 3 moves downwards under the action of the filter screen 3, the water way is opened, and the water inlet valve returns to the normal working state.
The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
