[0039] Please combine Figures 1 to 9 , the gas filtering device provided by the present invention is now described.

[0040] The gas filter device is used for air intake filtration of the compressor, and the gas filter device includes a housing 1, an air intake pipe 2, an air outlet pipe 3 and a cleaning assembly 4. The air intake pipe 2 is connected to the housing 1 and is close to the bottom side of the housing 1. The air outlet pipe 3 is connected to the upper side of the housing 1 and is connected to the air intake of the compressor. The cleaning assembly 4 includes a mounting plate 41, a driving module 42, an abutment plate 43, a filter plate 44, a first elastic member 45 and a stopper 46. The mounting plate 41 is fixedly connected to the outer wall of the air intake pipe 2, one end of the filter plate 44 is rotatably connected to the mounting plate 41, the first elastic member 45 is elastically connected between the filter plate 44 and the mounting plate 41, the stopper 46 is installed on the mounting plate 41, and the driving module 42 is installed on the mounting plate 41 and fixedly connected to the abutment plate 43. Specifically, the first elastic member 45 can be a spring.

[0041] The driving module 42 drives the abutting plate 43 to move toward the direction approaching the filter plate 44 , so that the abutting plate 43 can abut against the filter plate 44 , and the filter plate 44 can cover the pipe opening of the air intake pipe 2 .

[0042] The driving module 42 can also drive the abutment plate 43 to move away from the filter plate 44 so that the abutment plate 43 is separated from the filter plate 44. The elastic force of the first elastic member 45 drives the filter plate 44 away from the pipe opening of the intake pipe 2 and abuts against the blocking rod 46.

[0043] It can be understood that the air inlet pipe 2 of the gas filtering device is connected to the box body 1 and is close to the bottom side of the box body 1, the air outlet pipe 3 is connected to the upper side of the box body 1 and is connected to the air inlet of the compressor, the mounting plate 41 is fixedly connected to the outer wall of the air inlet pipe 2, one end of the filter plate 44 is rotatably connected to the mounting plate 41, the first elastic member 45 is elastically connected between the filter plate 44 and the mounting plate 41, the blocking rod 46 is installed on the mounting plate 41, the driving module 42 is installed on the mounting plate 41, and is fixedly connected to the abutment plate 43, and the driving module 42 drives the abutment plate 43 to move closer to the mounting plate 41. The filter plate 44 moves in the direction of the filter plate 44 so that the abutment plate 43 can abut the filter plate 44. The filter plate 44 can cover the pipe opening of the air intake pipe 2 so that impurities can be filtered. The driving module 42 can also drive the abutment plate 43 to move in the direction away from the filter plate 44 so that the abutment plate 43 is separated from the filter plate 44. The elastic force of the first elastic member 45 drives the filter plate 44 away from the pipe opening of the air intake pipe 2 and abuts against the blocking rod 46, while generating an impact force, so that the impurities and dust filtered by the filter plate 44 can fall off the filter plate 44, making cleaning convenient, thereby improving practicality.

[0044] It should be noted that when the compressor starts working, the gas enters the intake pipe 2 from the filter plate 44, the gas in the intake pipe 2 then enters the box body 1, and the gas in the box body 1 enters the compressor through the outlet pipe 3. After the compressor has been working for a period of time, impurities and other substances will accumulate on the filter plate 44. At this time, the drive module 42 drives the abutment plate 43 to move away from the filter plate 44 so that the abutment plate 43 does not abut against the filter plate 44. The elastic force of the first elastic member 45 drives the filter plate 44 away from the pipe opening of the intake pipe 2 and abuts against the blocking rod 46, while generating an impact force, so that the impurities and dust filtered by the filter plate 44 can fall off the filter plate 44.

[0045] In this embodiment, the abutting plate 43 is provided with a first abutting surface 431 , and the filter plate 44 is provided with a second abutting surface 441 . The first abutting surface 431 can abut against the second abutting surface 441 , so that the filter plate 44 can cover the pipe opening of the air intake pipe 2 .

[0046] Furthermore, the gas filter device further comprises a guide member 5, which is mounted on the mounting plate 41 and slidably connected to the abutment plate 43. By providing the guide member 5, the abutment plate 43 can move along the extension direction of the guide member 5, so that the abutment plate 43 can abut against the filter plate 44.

[0047] Furthermore, the gas filtering device further includes a second elastic member 49, which is elastically connected between the mounting plate 41 and the abutment plate 43. Specifically, the second elastic member 49 can be a spring. When the abutment plate 43 moves away from the filter plate 44 along the extension direction of the guide member 5, the second elastic member 49 can be elastically deformed under the extrusion of the abutment plate 43 and the mounting plate 41. When the impurities on the filter plate 44 are cleaned, or the filter plate 44 opens the pipe opening of the intake pipe 2, the elastic deformation force of the second elastic member 49 can drive the abutment plate 43 to move in the direction of the filter plate 44, so that the abutment plate 43 can abut the filter plate 44.

[0048] Further, the cleaning assembly 4 also includes a limit plate 47 and a third elastic member 48, the middle part of the limit plate 47 is rotatably connected to the mounting plate 41, one end of the limit plate 47 is elastically connected to the mounting plate 41 through the third elastic member 48, and the limit plate 47 is provided with a third abutting surface 471, and the third abutting surface 471 abuts against the second abutting surface 441. Specifically, the third elastic member 48 can be a spring. Since the middle part of the limit plate 47 is rotatably connected to the mounting plate 41, the third elastic member 48 is elastically connected to one end of the limit plate 47 and the mounting plate 41, due to the elastic force of the third elastic member 48, the third abutting surface 471 abuts against the second abutting surface 441, so that the filter plate 44 can cover the pipe opening of the intake pipe 2 more stably. The middle part of the limit plate 47 is rotatably connected to the wall surface of the mounting plate 41 through the rotating shaft.

[0049] Furthermore, the limiting plate 47 is further provided with a first protrusion 472, and the abutting plate 43 is provided with a second protrusion 432. The abutting plate 43 moves in a direction away from the filter plate 44, and the abutting plate 43 drives the second protrusion 432 to move, and the second protrusion 432 abuts against the first protrusion 472, so that the third abutting surface 471 moves away from the second abutting surface 441. Specifically, during the movement of the abutting plate 43 in a direction away from the filter plate 44, the abutting plate 43 moves along the extension direction of the guide member 5, the abutting plate 43 and the mounting plate 41 squeeze the second elastic member 49, the abutting plate 43 drives the second protrusion 432 to move, and the second protrusion 432 abuts against the first protrusion 472, so that the limiting plate 47 swings, and the limiting plate 47 drives the third elastic member 48 to elastically deform, so that the third abutting surface 471 moves away from the second abutting surface 441, the first abutting surface 431 moves away from the second abutting surface 441, and the elastic deformation of the first elastic member 45 The elastic deformation force drives the filter plate 44 to open the pipe opening of the air intake pipe 2. When the impurities in the filter plate 44 are cleaned, the elastic deformation force of the second elastic member 49 drives the abutment plate 43 to move toward the filter plate 44, and the abutment plate 43 drives the second protrusion 432 to move away from the first protrusion 472. The elastic deformation force of the second elastic member drives the limiting plate 47 to reset, so that the first abutment surface 431 can abut against the second abutment surface 441, and the third abutment surface 471 abuts against the second abutment surface 441, so that the filter plate 44 can cover the pipe opening of the air intake pipe 2.

[0050] Furthermore, the driving module 42 includes a pipe 421 and a piston block 422. The pipe 421 is connected to the housing 1. The piston block 422 is slidably connected to the pipe 421 and fixedly connected to the abutment plate 43. When the filter plate 44 is blocked, negative pressure is generated in the housing 1. Since the housing 1 is connected to the pipe 421, the negative pressure will attract the piston block 422 to move in the pipe 421 in a direction away from the filter plate 44, so that the piston block 422 drives the abutment plate 43 to move, so that the filter plate 44 can open the pipe opening of the air intake pipe 2. After the filter plate 44 is cleaned, the negative pressure in the housing 1 disappears, and the elastic deformation force of the second elastic member drives the abutment plate 43 to reset, so that the filter plate 44 can cover the pipe opening of the air intake pipe 2.

[0051] Furthermore, the pipe opening of the air intake pipe 2 is provided with a plurality of evenly distributed filter holes 21. In this way, when the filter plate 44 is opened, impurities will not enter the interior through the pipe opening of the air intake pipe 2.

[0052] Furthermore, the gas filtering device further includes a gas refiner 6, which includes an upper plate 61 and a lower plate 62. The upper plate 61 and the lower plate 62 are installed in the box body 1 to form a gap, and the gas outlet end of the air inlet pipe 2 is arranged at the gap. By arranging the gas refiner 6, after the air inlet pipe 2 enters the gas refiner 6, the gas will be refined and dispersed by the holes of the upper plate 61 and the lower plate 62.

[0053] Furthermore, oil is provided in the box body 1, and the level of the oil is higher than the horizontal plane where the upper plate 61 is located. The finely dispersed gas will pass through the oil to filter out fine impurities, and then enter the gas outlet pipe 3.

[0054] Furthermore, the box body 1 is provided with an inlet pipe 11 and an outlet pipe 12 of the oil, and the inlet pipe 11 and the outlet pipe 12 are respectively connected to the box body 1. In this way, the oil can be replaced. When the oil does not need to be replaced, the inlet pipe 11 and the outlet pipe 12 are closed respectively.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
