Description

Technical Field

[0001] The utility model specifically relates to the technical field of gas filtration, and specifically relates to a multi-stage filtration type air filtration mechanism and an air pump. Background Art

[0002] A vehicle-mounted air pump, also known as an inflator, air compressor, or air pump, is a portable device that works by the operation of an internal motor and is used to inflate vehicle tires, bicycle tires, inflatable mattresses, hovercrafts, etc. The working principle of the vehicle-mounted air pump is that when the motor runs, during air extraction, the valve of the connector is pushed open by the air pressure of the atmosphere, and the gas enters the air cylinder. When inflating the tire, the valve is closed by the air pressure in the air cylinder, and the gas then enters the tire.

[0003] When the existing vehicle-mounted air pump is in use, it often inhales impurities such as dust in the air. The gas containing impurities will exacerbate the wear of parts, resulting in the air pump getting stuck and burned out, thus affecting the service life of the vehicle tire. Especially when used in a sandy environment, the air pump will inhale a large amount of sand, increasing the damage rate of the air pump and the tire. Summary of the Utility Model

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-5, in the embodiment of the present utility model, a multi-stage filtering air filtering mechanism includes a primary filtering cylinder 10, a secondary filtering cylinder 20, and a tertiary filtering cylinder 30. One side of the secondary filtering cylinder 20 is detachably connected to the primary filtering cylinder 10, and the other side of the secondary filtering cylinder 20 is detachably connected to the tertiary filtering cylinder 30. An air inlet 40 is provided on the primary filtering cylinder 10, and an air outlet 50 is provided on the tertiary filtering cylinder 30. The air inlet 40 is used to introduce external environmental air, and the air outlet 50 is used to connect to an inflation pipeline. The inflation pipeline is connected to the air inlet end of an air inflation pump. The primary filtering cylinder 10, the secondary filtering cylinder 20, and the tertiary filtering cylinder 30 are used to filter and clean the external environmental air to improve the cleanliness of the air entering the air inflation pump.

[0022] In the embodiment of the present application, as Figures 2-4 shown, a conical filter cylinder 11, an aggregate tray 12, and a rotating base 13 are provided inside the primary filtering cylinder 10. The primary filtering cylinder 10 is in communication with the air inlet 40; the aggregate tray 12 is fixedly connected to the bottom of the conical filter cylinder 11. As can be seen from Figure 3 , the aggregate tray 12 is of an annular structure and is arranged outside the bottom of the conical filter cylinder 11; the rotating base 13 is rotatably installed inside the conical filter cylinder 11 and is arranged outside the aggregate tray 12. A number of top blocks 131 are provided on the side of the rotating base 13 facing the aggregate tray 12. The top blocks 131 are connected to the inner wall of the rotating base 13 through elastic members. A number of protrusions 121 that cooperate with the top blocks 131 are provided on the outside of the aggregate tray 12. A number of material discharge openings 122 are also formed in the aggregate tray 12. After the external environmental air is introduced into the primary filtering cylinder 10 through the air inlet 40, the conical filter cylinder 11 filters the gas, and the dust particles in the gas are intercepted on the surface of the conical filter cylinder 11. As the filtering progresses, the amount of dust particles accumulated on the surface of the conical filter cylinder 11 continuously increases. When the rotating base 13 is in a rotating state, the top blocks 131 come into contact with the protrusions 121. The protrusions 121 squeeze the top blocks 131, causing the elastic members to compress. After the top blocks 131 are separated from the protrusions 121, the elastic members drive the top blocks 131 to strike the aggregate tray 12, causing the conical filter cylinder 11 to vibrate, and the dust accumulated on the surface of the conical filter cylinder 11 falls into the aggregate tray 12;

[0023] Further, in the embodiment of the present application, the upper part of the conical filter cartridge 11 is connected to the primary filter cartridge 10 through an elastic connecting member 111. A blanking seat 123 is provided at the lower part of the conical filter cartridge 11. The blanking seat 123 is fixedly installed at the bottom of the aggregate tray 12. The blanking seat 123 is a hollow structure and is communicated with the blanking port 122. A driving motor 18 is fixedly installed inside the primary filter cartridge 10. The output end of the driving motor 18 is fixedly installed with a driving gear 181. A toothed ring 132 is fixedly installed at the bottom of the rotating seat 13. The driving gear 181 meshes with the toothed ring 132. When the driving motor 18 works, it controls the rotation of the driving gear 181, so that the driving gear 181 drives the toothed ring 132 and the rotating seat 13 to rotate.

[0024] Still further, in the embodiment of the present application, a fixing seat 14 is further provided inside the primary filter cartridge 10. The fixing seat 14 is fixedly connected to the inner wall of the primary filter cartridge 10 and is arranged below the blanking seat 123. A start button 19 is arranged on the side of the fixing seat 14 facing the blanking seat 123. A controller 17 is also arranged on the fixing seat 14. The start button 19 is electrically connected to the controller 17. The controller 17 is electrically connected to the driving motor 18. The controller 17 includes a motor start-stop module and a timing module. When the dust on the surface of the conical filter cartridge 11 gradually increases, the mass of the conical filter cartridge 11 increases and drives the blanking seat 123 to move towards the fixing seat 14. When the blanking seat 123 contacts the start button 19, the start button 19 controls the driving motor 18 to start through the motor start-stop module of the controller 17, so that the rotating seat 13 rotates. During this process, the controller 17 performs timing. After the timing is completed, the motor start-stop module controls the driving motor 18 to stop working, and the rotating seat 13 stops rotating. The conical filter cartridge 11 completes dust cleaning during the timing process.

[0025] In addition, in the embodiment of the present application, the bottom of the conical filter cartridge 11 is connected to a second blanking pipe 16. The gas enters the second blanking pipe 16 after being filtered by the conical filter cartridge 11 and finally discharges from the lower end of the second blanking pipe 16. A first connection port 102 is provided at the bottom of the primary filter cartridge 10. The first connection port 102 is communicated with the second blanking pipe 16 through an elastic connecting pipe 161. One side of the secondary filter cartridge 20 is detachably installed in the first connection port 102. The gas filtered by the primary filter cartridge 10 enters the interior of the secondary filter cartridge 20 through the first connection port 102. A dust discharge port 101 is opened outside the primary filter cartridge 10. The bottom of the blanking seat 123 is further connected to a first blanking pipe 15. The dust discharge port 101 is communicated with the first blanking pipe 15 through a first connecting pipe 151. The first connecting pipe 151 is a flexible pipe structure. The dust particles inside the blanking seat 123 are discharged from the dust discharge port 101 through the first blanking pipe 15 and the first connecting pipe 151.

[0026] In the embodiment of the present application, an annular filter screen 21 is installed inside the secondary filter cylinder 20. A second connection port 31 is provided outside the annular filter screen 21 at the bottom of the secondary filter cylinder 20. Gas enters the inside of the annular filter screen 21 through the first connection port 102 and is discharged from the second connection port 31 after filtration.

[0027] Further, in the embodiment of the present application, a filtering mechanism 32 is provided inside the tertiary filter cylinder 30. The filtering mechanism 32 includes an annular seat 321 and an exhaust seat 325 fixedly installed inside the tertiary filter cylinder 30. The exhaust seat 325 is communicated with the annular seat 321 through a plurality of second connecting pipes 323. A plurality of gas inlets 322 are provided on the annular seat 321. A gas outlet is provided at the bottom of the exhaust seat 325, and the gas outlet is communicated with the exhaust port 50. A plurality of filter discs 324 are arranged on the second connecting pipes 323 along the gas flow direction. After the gas enters the inside of the annular seat 321, it is divided into multiple strands by the second connecting pipes 323. The multiple strands of gas sequentially pass through the filter discs 324 and are discharged from the gas outlet at the bottom of the exhaust seat 325. By diverting the gas, the gas is brought into full contact with the filter discs 324, improving the filtering effect of the gas.

[0028] An air pump is connected to the above-mentioned multi-stage filtering type air filtering mechanism. Specifically, the air inlet end of the air pump is communicated with the exhaust port 50 of the multi-stage filtering type air filtering mechanism through an air filling pipeline.
