[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a technical solution, please refer to Figure 1 and Figure 2 , an air-conditioning refrigerant circulation filter, comprising: an inlet pipe 1, a filter box 2, an outlet pipe 3 and a shunt pipe 4. This scheme is a structural improvement of the non-electronic component part of the air-conditioning refrigerant circulation filter in the prior art, wherein the inlet pipe 1, the filter box 2, the outlet pipe 3 and the shunt pipe 4 are common air-conditioning refrigerant circulation filter products that have been promoted in the prior art. The inlet pipe 1 and the outlet pipe 3 can make the refrigerant flow, and the filter box 2 can filter the refrigerant.

[0024] The outside of the inlet pipe 1 and the outlet pipe 3 are both sleeved with flanges 31, and the outside of the flanges 31 is polished. The flanges 31 are convenient for connecting the inlet pipe 1 and the outlet pipe 3 with external machinery. A groove 21 is provided on the inner back of the filter box 2, and the groove 21 is slidably connected to the collecting box 54. The groove 21 is convenient for limiting the collecting box 54. The filter box 2 is connected to the bottom of the inlet pipe 1, the outlet pipe 3 is connected to the bottom of the filter box 2, the diverter pipe 4 is connected between the outlet pipe 3 and the outside of the filter box 2, and the inside of the filter box 2 is connected with a filtering mechanism 5.

[0025] See also Figure 3 and Figure 4 The filtering mechanism 5 includes a water collecting box 51, a filter plate 53 and a collecting box 54. The water collecting box 51 can centrally process the refrigerant, the filter plate 53 can filter the refrigerant, and the collecting box 54 can collect the filtered impurities. The water collecting box 51 is connected to the bottom of the inlet pipe 1, and the water collecting box 51 is connected to the filter box 2. The bottom of the water collecting box 51 is connected to a drain pipe 52. The bottom of the drain pipe 52 is a wide-mouth design, and the interior of the drain pipe 52 is polished. The wide-mouth design of the drain pipe 52 can spray the refrigerant on the top of the filter plate 53, and then rinse the top of the filter plate 53.

[0026] The filter plate 53 is installed inside the filter box 2, and the filter plate 53 is slidably connected to the inside of the filter box 2. The outside of the filter plate 53 is connected to the inside of the filter box 2 by bolts, and filter holes are evenly spaced on the top of the filter plate 53. The filter plate 53 can be removed from the inside of the filter box 2 for replacement. The collection box 54 is slidably connected to the filter box 2. The front of the collection box 54 is fixedly connected with a sealing gasket 541, which is a common sealing sleeve in the prior art, and the sealing gasket 541 is slidably connected to the filter box 2. The front of the sealing gasket 541 is fixedly connected with a pull ring 542, and the outside of the pull ring 542 is polished. The sealing gasket 541 can seal the collection box 54 and the filter box 2, and the pull ring 542 makes it convenient for the staff to pull the collection box 54 out of the inside of the filter box 2.

At the same time, the discharged air-conditioning refrigerant can also pass through mechanical devices such as an external pump body, enter the interior of the inlet pipe 1 for filtration and use, so as to achieve the purpose of recycling.

[0028] Impurities in the air-conditioning refrigerant will be retained on the top of the filter plate 53. Through the inclined surface of the filter plate 53 and the spraying of the air-conditioning refrigerant from the bottom of the drain pipe 52, the top of the filter plate 53 is flushed, and the impurities will roll into the inside of the collection box 54, and then be discharged through the collection box 54. At the same time, the staff can pull the collection box 54 out of the inside of the filter box 2 through the pull ring 542 to clean and maintain the collection box 54.

[0029] When the air-conditioning refrigerant is circulating and filtering, the air-conditioning refrigerant can be filtered through the added filtering mechanism 5. At the same time, the intercepted impurities can be quickly cleaned through the inclined design of the filter plate 53 and the inclined wide-mouth design of the drain pipe 52 to prevent the impurities from clogging the filter plate 53. At the same time, the staff can also quickly clean and maintain the impurities through the added collection box 54 to avoid the need to disassemble and maintain the device and consume a lot of time.
