[0003] The prior art has the following technical defects:

[0004] In the above-mentioned centrifugal air compressor, the dust removal brush rotates synchronously with the air collecting fan. Although it has the effect of continuously cleaning the dust and lint attached to the outer surface of the filter, when the air compressor is running, the continuous rotation of the dust removal brush may interfere with the airflow, causing unstable airflow or generating vortices, affecting the smoothness of the airflow in the intake duct. In addition, the dust removal brush is in continuous contact with the outer surface of the filter, which can easily cause friction loss, aggravate the damage of the filter, and cause impurities to enter the intake duct, affecting the air quality and the performance of the compressor. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to overcome the shortcomings of the prior art and to provide an air intake device with a self-cleaning filter air compressor, which can reduce the interference of components such as dust removal brushes on the airflow, and the friction loss caused by the dust removal brush continuously cleaning the filter plate.

[0006] The utility model discloses an air intake device with a self-cleaning filtering air compressor, comprising an air intake pipe, a filter plate is arranged in the air intake pipe, a branch pipe is connected to the bottom side of the air intake pipe near the filter plate, a pipe cover is installed at the bottom of the branch pipe, a transmission rod is rotatably connected at the center of the pipe cover, a first gear is fixedly connected to the lower part of the transmission rod, the first gear is meshingly connected to the second gear, the second gear is connected to a servo motor, a threaded rod and a sliding rod are movably connected in the transmission rod, the threaded rod is threadedly connected to the inside of the transmission rod, the sliding rod is arranged at the top of the threaded rod and is slidably connected to the inside of the transmission rod, a baffle is rotatably connected to the top of the sliding rod, a bevel gear set is arranged on the sliding rod, the bevel gear set is fixedly connected to the second connecting rod, the end of the second connecting rod is fixedly connected to the first brush plate, the middle part of the second connecting rod is rotatably connected to the first connecting rod, and the first connecting rod is fixedly connected to the baffle.

[0007] Working process or working principle:

[0008] When cleaning the filter plate, rotate the threaded rod to push the slide rod to move upward in the transmission rod until the baffle contacts the intake pipe, and the baffle diameter directly fits the inner diameter of the branch pipe. At this time, the second connecting rod is opposite to the center point of the filter plate, and the transmission rod cannot rotate under the restriction of the gear set and the output end of the servo motor. Start the servo motor, and drive the transmission rod to rotate through the meshing of the gear set, and then drive the second connecting rod to rotate synchronously through the bevel gear set. The surface of one side of the filter plate is cleaned by the first brush plate, and the dust device attached to the surface of the filter plate is brushed to achieve the effect of automatic cleaning. After cleaning, turn off the servo motor and reverse the threaded rod to reset the slide rod. During the resetting process, the baffle will block the inside of one end of the branch pipe to reduce the airflow entering the inside of the branch pipe, which can reduce the interference of the relative components such as the filter plate set on the airflow, and reduce the friction loss generated when the first brush plate continuously cleans the filter plate, so that subsequent personnel can replace the filter plate according to its specified service life, reduce the shortening of the life due to friction loss, and cause the filter plate to be damaged in advance, resulting in the harm caused by impurities entering the intake pipe.

[0009] The outer wall of the branch pipe and the outer wall of the pipe cover are both provided with pipe threads, the branch pipe and the pipe cover are connected by a threaded ring, a plurality of groups of plug rods are fixed around the edge of the branch pipe, and the end face of the branch pipe is provided with slots corresponding to the plug rods one by one. The disassembly work between the branch pipe and the pipe cover can be completed by completely rotating the threaded ring onto the outer wall of the branch pipe, so as to facilitate the cleaning of impurities stored inside the branch pipe. At the same time, the plug-in method of the plug rod in conjunction with the slot can reduce the phenomenon of random rotation between the pipe cover and the branch pipe, so as to improve the stability of the device.

[0010] A second cleaning brush is installed on the outer wall of the transmission rod, and a third connecting rod is fixedly connected to one side of the inside of the branch pipe. The second cleaning brush can be used to clean the inner wall of the branch pipe to reduce the subsequent attachment of dust and impurities to the inner wall of the branch pipe. During the rotation of the second cleaning brush, the brush end contacts the third connecting rod for elastic deformation. During the deformation process, impurities attached to the brush end are detached, thereby improving the cleanliness of the second cleaning brush and improving its cleaning effect.

[0011] An elastic cloth is fixedly connected to the baffle, and the other end of the elastic cloth extends to the middle of the branch pipe and is fixedly connected thereto. The elastic cloth can block and limit the smoke and dust generated during cleaning, thereby reducing the dispersion of dust inside the intake pipe and causing subsequent secondary pollution, thereby improving the cleaning effect of the filter plate each time and the use cycle after cleaning.

[0012] A guide plate is installed at one end of the pipe cover. The guide plate is shaped as a central protrusion. Impurities that fall onto the end surface of the pipe cover can slide down through the guide plate, so that the impurities can be quickly processed later.

[0013] A rotating block is installed at the end of the threaded rod, and the outer wall of the rotating block is provided with anti-skid patterns. The rotating block can facilitate personnel to rotate the threaded rod, and the setting of the anti-skid patterns can increase the friction between the rotating block surface and the hand, reducing the occurrence of slipping.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model only needs to rotate the threaded rod forward to start the servo motor to automatically clean the surface of one side of the filter plate, and reverse the threaded rod to reset the relative cleaning component to the inside of the branch pipe, so as to reduce the interference of the relative elements such as the filter plate on the airflow, and the friction loss caused by the first brush plate continuously cleaning the filter plate.
