Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an air compressor with a cleaning function. Background Art

[0002] A compressor is a positive displacement gas compression machine whose working volume performs rotational motion. The compression of gas is achieved by the change of volume, which is in turn achieved by a pair of rotors of the compressor performing rotational motion inside the casing. Screw air compressors are used to compress air and provide power for factory production lines, engineering machinery and other systems. Compared with traditional piston air compressors, screw air compressors have the characteristics of high energy efficiency, compact structure and low noise. In recent years, there has been a trend of gradually replacing piston air compressors in various fields.

[0003] When the air compressor takes in air, there is a lack of a clean structure for inhaling air, which results in low cleanliness inside the air compressor.

[0004] For example, an air compressor with a cleaning function disclosed in Chinese patent CN114635852A has a cleaning mechanism added to the outer end of the air inlet pipe, an internal threaded ring surface is arranged around the inner part of the outer end of the air inlet pipe, and a connecting ring body is screwed onto the internal threaded ring surface around the inner part of the outer end of the air inlet pipe, and a filter filler is installed in the middle of the connecting ring body, so that the inhaled air is filtered by the filter filler, and the filter filler can be movably connected with the help of the connecting ring body, and disassembly and installation are very convenient.

[0005] However, when the filter filler is clogged by impurities in the air during use of the device, the filter filler needs to be frequently replaced, which is inconvenient to use.

[0006] For this reason, we urgently need to provide an air compressor with a cleaning function. Utility Model Content

[0009] The cleaning device comprises a cleaning unit and a disassembly unit. The cleaning unit is arranged on the right side of the air inlet pipe, and the disassembly unit is arranged on the top of the cleaning unit.

[0010] The cleaning unit includes a filter box, a connecting pipe, an air inlet pipe, a filter, a handle, a connecting rod, a brush and a push-pull rod. The filter box is arranged on the right side of the air inlet pipe, the connecting pipe is connected to the left side of the filter box, the air inlet pipe is connected to the right side of the filter box, the filter is installed inside the filter box, the handle is fixedly installed on the top of the filter box, the connecting rod is fixedly installed inside the filter box at the front and rear ends of the right side of the filter, the front and rear ends of the brush are slidably connected to the outside of the connecting rod, and the push-pull rod is fixedly installed on the top of the brush.

[0011] Preferably, the disassembly unit includes a connecting block, a pressure block, a spring and a push rod, the connecting block is fixedly installed at the front and rear ends of the top of the filter box, the pressure block is slidably connected to the inside of the connecting block, the spring is installed inside the connecting block, and the push rod is fixedly installed on the left side of the pressure block.

[0012] Preferably, the air inlet pipe is provided with an internal thread, and the connecting pipe is provided with an external thread, and the connecting pipe is threadedly connected to the air inlet pipe, so that the filter box can be installed on the right side of the air inlet pipe.

[0013] Preferably, the upper end of the push-pull rod extends to the outside of the filter box. When the filter is clogged by impurities in the air, the push-pull rod is pushed up and down to drive the brush to move up and down along the connecting rod to scrape off the dust on the surface of the filter.

[0014] Preferably, one end of the spring is fixedly connected to the inner wall of the connecting block, and the other end is fixedly connected to one side of the pressing block. The spring squeezes the inner wall of the connecting block to push the pressing block to move to the right, thereby limiting the upper part of the filter screen through the pressing block to prevent the filter screen from jumping up and down when it is vibrated.

[0015] Preferably, a rectangular through slot is provided on the upper surface of the filter box, and the filter screen can be easily installed and removed through the rectangular through slot.
