[0002] The full name of air compressor is air compressor. It is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy. It is an air pressure generating device for compressed air. In order to ensure the normal use of the air compressor and make the air compressor suitable for a variety of working environments, the air compressor usually needs to be equipped with an air filter at its air inlet end when in use.

[0003] There are many types of filtering devices on the market, among which there is a cylindrical filtering device. During use, air will enter the filtering device from the air inlet pipe on one side of the device, and will be filtered by the filter element in the filtering device. The filtered air will be discharged through the air outlet pipe. In this process, a large amount of dust will accumulate on the side of the filter element facing the air inlet pipe, causing blockage, while the part far away from the air inlet pipe is not fully utilized, thereby reducing the utilization rate of the filter element. For this reason, we propose an air compressor filtering device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] Reference Figure 1-7 A filter device for an air compressor includes a shell 1, a filter structure 2 is arranged in the shell 1, the filter structure 2 includes an auxiliary component 3, a filter cartridge 4 is arranged in the auxiliary component 3, the auxiliary component 3 includes an auxiliary component 301, a transmission component 302 is arranged on one side of the auxiliary component 301, and the transmission component 302 corresponds to the auxiliary component 301.

[0030] An air inlet pipe 101 is fixedly connected to one side of the shell 1, and an air outlet pipe 102 is fixedly connected to the bottom of the shell 1. The air outlet pipe 102 is connected to the air inlet end of an air compressor (the air compressor is not shown in the figure). A cover 103 is threadedly connected to the top of the shell 1.

[0031] The auxiliary component 301 includes two limiting rings 3011 fixedly connected to the outer shell 1, a plurality of connecting rods 3012 are arranged between the two limiting rings 3011, the connecting rod 3012 rotates between the two limiting rings 3011, a positioning ring 3013 is fixedly connected to the connecting rod 3012, a plurality of positioning rods 3014 are fixedly connected to the top of the positioning ring 3013, and a driven wheel 3015 is fixedly connected to the outer surface of the positioning ring 3013.

[0032] The transmission assembly 302 includes a mounting plate 3021 fixedly connected to the housing 1, and a motor 3022 is fixedly connected to the bottom of the mounting plate 3021. The motor 3022 is a prior art and will not be described in detail here. A protective box is provided on the outside of the motor 3022. The setting of the protective box and the mounting plate 3021 can seal the motor 3022 to prevent dust and other objects from entering the motor 3022. A rotating shaft 3023 is fixedly connected to the output end of the motor 3022. One end of the rotating shaft 3023 passes through the mounting plate 3021 and extends a portion. A rotating rod 3024 is rotatably connected to the mounting plate 3021. The rotating shaft 3023 and the rotating rod 3024 are connected for transmission through a transmission member 3025. The transmission member 3025 is composed of two pulleys and a belt, which is a prior art. A driving wheel 3026 is fixedly connected to one end of the rotating rod 3024, and the driving wheel 3026 is meshed with the driven wheel 3015.

[0033] A circular ring 401 is fixedly connected to the outer surface of the filter cartridge 4. The outer diameter of the circular ring 401 does not exceed the inner diameter of the mounting plate 3021. A pair of sockets 4011 are provided on the circular ring 401. The filter cartridge 4 is located in the positioning ring 3013, and the diameter of the filter cartridge 4 is the same as the inner diameter of the positioning ring 3013. The circular ring 401 corresponds to the positioning ring 3013, and the sockets 4011 correspond to the positioning rod 3014.

[0034] Before use, place the filter cartridge 4 into the positioning ring 3013, and align the insertion hole 4011 on the ring 401 with the positioning rod 3014 until the ring 401 falls on the positioning ring 3013, and then cover the cover 103. When replacing the filter cartridge 4, just open the cover 103 and take out the old filter cartridge 4 and replace it with a new one.

[0035] During use, air will enter the device through the air inlet pipe 101. At this time, the filter cartridge 4 will filter the incoming air, and the filtered air will be discharged through the air outlet pipe 102. In this process, the motor 3022 will drive the rotating shaft 3023 to rotate. Since the rotating shaft 3023 and the rotating rod 3024 are connected by the transmission member 3025, the rotating rod 3024 will rotate simultaneously with the rotating shaft 3023. When the rotating rod 3024 rotates, it will drive the driving wheel 3026 to rotate. Since the driving wheel 3026 is meshed with the driven wheel 3015, the driven wheel 3015 will drive the positioning ring 3013 to rotate. At this time, the connecting rod 3012 rotates between the two limit rings 3011, and when the positioning ring 3013 rotates, it will drive the circular ring 401 to rotate. When the circular ring 401 rotates, it will drive the filter cartridge 4 to rotate, so that the side of the filter cartridge 4 is fully in contact with the incoming air, thereby increasing the utilization rate of the filter cartridge 4.
