As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 3, the air conditioner filter of the present application includes a casing 102, a connecting pipe 101 and a filter screen 204, the connecting pipe 101 is screwed to two axial ends of the tubular casing 102, a first valve body for cutting off fluid flow is disposed at a joint of the casing 102 and the connecting pipe 101, a hollow bump is formed at the middle of the casing 102, a cover 105 is screwed to an outer end of the cylindrical bump, and a sealing ring for preventing refrigerant leakage is attached to an inner wall of the cover 105. The filter 204 extends into the cavity defined by the protrusion and the cover 105 and into the refrigerant for filtering impurities. And a second valve body which is communicated with the cavity and used for vacuumizing is fixedly arranged on the side part of the bump. Preferably, the second valve body is a needle valve 106, and the outer end sleeve of the needle valve is provided with a needle valve cap 107. The needle valve 106 may be connected to a vacuum pump for vacuum pumping or refrigerant charging and discharging. The air conditioner filter of this application mainly is applied to in the air conditioner, through refrigerant union coupling in connecting pipe 101 and the air conditioner, the refrigerant flows in by the connecting pipe 101 of one end, passes through the first valve body of one side, casing 102, the first valve body of opposite side in proper order, flows out other end connecting pipe 101 at last. When the air conditioner has unit faults caused by filter blockage, the refrigerant flowing into the shell 102 is cut off through the first valve body, so that the refrigerant is reserved in the shell 102 without releasing the refrigerant, and a large amount of time and refrigerant resources are saved; then, the cover body 105 is screwed out, and the filter screen 204 is taken out from the cavity for replacement or cleaning, so that a new filter does not need to be welded, the problem of filth blockage in the air conditioner is solved, and the air conditioner is quick, convenient, economic and environment-friendly; finally, a vacuum pump externally connected with the needle valve 106 is used for vacuumizing the refrigerant of the shell section, or when part of the refrigerant needs to be replaced, the refrigerant flow is adjusted, and then the cover body 105 is screwed tightly, so that the refrigerant in the shell 102 is restored to a sealing state, the operation is simple and convenient, and the unit is stable.

In some embodiments, the inner wall of the protrusion is formed with at least one vertically arranged groove, and the filter screen 204 slides into the refrigerant under the guidance of the groove and is clamped by the groove. The design structure is simple and is beneficial to quick drawing and releasing of the filter screen. Specifically, the grooves are distributed on the inner wall of the periphery of the bump in pairs. The paired grooves guide the filter screen 204 smoothly and stably, and the filter screen 204 is stably erected in the housing 102 under the impact of the refrigerant, thereby playing an effective and lasting filtering effect on impurities in the refrigerant. Preferably, the transverse cross section of the filter screen 204 is a semi-arc shape, so that impurities in the system can be adsorbed on the filter screen 204, and the impurities cannot fall off when the filter screen 204 is drawn out, thereby effectively filtering the impurities carried by the refrigerant. It should be noted that the filter screen 204 may also be designed with a transverse cross section of a cone shape, an arc shape, or a polygon shape, and only a structure that the filter screen 204 is recessed toward one side is required, and of course, the depth of the recess is preferably deeper.

In some embodiments, the first valve body is a ball valve, and includes a valve core 202 accommodated in a housing 102 and a valve rod 203 connected to the valve core 202, wherein cylindrical protrusions 108 are formed on two side portions of the housing 102, and a knob 104 is sleeved on an end portion of the valve rod 203 extending out of the cylindrical protrusions 108. The knob 104 can be rotated left and right within a limited range, so as to drive the valve rod 203 to rotate the valve core 202, thereby opening or closing the pipeline. The ball valve cuts off the flow of the refrigerant, and the refrigerant can be tightly closed only by rotating 90 degrees or a small rotating moment. To further promote ease of rotation, the knob 104 is constructed as a bent piece with a recess formed in one side of the bent piece to match the top of the valve stem 203.

Preferably, the valve core 202 is provided with a sealing member 201 for preventing fluid leakage at both sides of the housing 102 in the axial direction and at a gap between the stem 203 and the stud bump 108.

The following describes the cleaning steps of the air conditioner filter in detail:

firstly, screwing the left knob 104 and the right knob 104 to ensure that the refrigerants on two sides of the filter do not flow into the shell and are in an isolated state; then the cover body 105 is screwed out, the filter screen 204 is drawn out, the filter screen is cleaned or replaced by a new filter screen and is put into the shell 102 along the groove, and the filter screen is tightly pressed in the shell by screwing the cover body 105; finally, a vacuum pump is connected from the needle valve 106 to vacuumize the filter, and the needle valve cap 107 is screwed after the vacuumization.

The application also provides an air conditioner adopting the air conditioner filter, which at least comprises the beneficial effects mentioned above, and the description is omitted.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which are within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
