Abstract
Description
An air compressor intake structure Technical Field
[0001] This utility model relates to the field of air compressor technology, and in particular to an air compressor intake structure. Background Technology
[0002] An air compressor converts the mechanical energy of an electric motor or diesel engine into gas pressure energy, providing compressed air for various equipment in tobacco production. On tobacco production lines, key equipment such as cigarette rolling machines and packaging machines require compressed air to drive and complete various technological actions. Publication No. CN212985484U discloses an air compressor intake structure and an air compressor. The intake structure includes an air duct, an air filter assembly, and an intake shroud. The air duct is connected to the compressor head via an intake valve. The air filter assembly is installed at the end of the air duct, and the intake shroud is installed on the air filter assembly. After the air filter assembly is installed and fixed inside the compressor housing, the intake shroud is pressed and fastened to the housing wall. Filter holes are provided at corresponding positions on the housing wall for filtering external air. This utility model's air compressor intake structure no longer draws air from inside the housing; instead, it directly draws air through the intake shroud and filter holes. The device draws in air filtered through the filter holes, reducing the temperature of the intake gas and preventing overheating of the compressor head and filter. It also prevents large amounts of gas from rushing into the chassis, avoiding problems such as dust accumulation that could clog the inverter and radiator. However, the air in actual tobacco processing workshops often contains a large amount of tobacco dust, making the compressor's filter screen prone to clogging. Furthermore, the filter screen is susceptible to deformation and damage after high-frequency use, affecting filtration efficiency and tobacco production capacity. This device does not offer effective solutions for filter cleaning and replacement and requires improvement. Summary of the Invention

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0035] Example 1
[0036] Please refer to Figures 1-10. This utility model provides a technical solution: an air compressor intake structure, including a housing 1. A dustproof frame 2 is rotatably connected to the surface of the housing 1. A dustproof plate 3 is fixedly installed on the surface of the dustproof frame 2, allowing the dustproof plate 3 to block a certain amount of dust falling from outside the air compressor intake structure from entering the air compressor intake structure. A torsion bolt 4 is rotatably connected inside the dustproof frame 2. A torsion groove 5 is provided inside the housing 1, allowing the dustproof frame 2 to be fixed to the housing 1 through the torsion bolt 4 and the torsion groove 5. A fixed bracket 6 is rotatably connected to the surface of the housing 1. A filter screen 7 is slidably connected to the surface of the fixed bracket 6, allowing the filter screen 7 to slide on the fixed bracket 6. When the air compressor intake structure is working, the filter screen 7 is basically parallel to the dustproof frame 2.
[0037] A motor 9 is fixedly installed inside the outer casing 1. A lead screw 13 is rotatably connected inside the outer casing 1, allowing the lead screw 13 to rotate on the outer casing 1. Vertically extending grooves are provided on both sides of the outer casing 1. A slide table 10 is slidably connected to one groove of the outer casing 1, allowing the slide table 10 to slide on the outer casing 1. A brush rod 11 is rotatably connected to the surface of the slide table 10, allowing the brush rod 11 to move with the slide table 10 and rotate simultaneously. Brush bristles 12 are fixedly connected to the surface of the brush rod 11. As shown in Figure 9, a gear 14 is fixedly connected to the surface of the brush rod 11, allowing the brush rod 11 to rotate with the gear 14. A pulley 16 is rotatably connected to one end of the brush rod 11. The pulley 16 is embedded in the groove on the other side of the outer casing 1.
[0038] A vertically extending rack 15 is fixedly connected to the outer casing 1. A snap fastener 8 is fixedly connected to the surface of the filter screen 7. The surface of the snap fastener 8 is slidably connected to the fixed bracket 6, so that the filter screen 7 can be fixed to the fixed bracket 6 by the snap fastener 8. A torsion bolt 4 is slidably connected to a torsion groove 5, so that the torsion bolt 4 can be fixed in the torsion groove 5. The output end of the motor 9 is fixedly connected to the lead screw 13, and the lead screw 13 is threadedly connected to the slide table 10, so that the motor 9 drives the lead screw 13 to rotate, thereby causing the slide table 10 to rotate and slide. The gear 14 meshes with the rack 15. The pulley 16 is embedded in a groove on the other side of the outer casing 1, so that the pulley 16 rotates and slides in the groove. The cooperation of the above components causes the gear 14 to rotate under the constraint of the pulley 16 and the rack 15, thereby keeping the brush rod 11 rotating smoothly and moving vertically.
[0039] Please refer to Figure 1-10. The outer casing 1 and the dust box 17 are detachably connected. The detachable connection is as follows: a push post 18 is slidably connected to the groove of the dust box 17, and an arc-shaped buckle 20 is fixedly connected to the side of the push post 18. A spring 19 is fixedly connected to the inner side of the push post 18, and the outer side of the push post 18 can extend through the hole on the outer casing 1 to the outside of the outer casing 1 for easy pressing. The spring 19 and the arc-shaped buckle 20 slide along with the push post 18 on the dust box 17. The inner bottom surface of the outer casing 1 is sloped. One end of the spring 19 is fixedly connected to the dust box 17, and the other end of the spring 19 abuts against the arc-shaped buckle 20 so that the arc-shaped buckle 20 can be engaged in the hole of the outer casing 1. The arc-shaped buckle 20 is slidably connected to the outer casing 1, allowing dust to fall into the dust box 17 on the slope. The spring 19 helps the push post 18 return to its original position, thereby allowing the arc-shaped buckle 20 to slide into the outer casing 1 to fix the dust box 17.
[0040] The aforementioned groove, push post 18, spring 19, and arc-shaped buckle 20 can be installed on both sides of the dust box 17.
[0041] Working principle: When there is excessive smoke and dust on the filter screen 7, the motor 9 is started. The motor 9 drives the lead screw 13 to rotate, causing the slide table 10 to slide under the constraint of the lead screw 13 and the groove of the outer shell 1. The sliding of the slide table 10 drives the brush rod 11 to move. The brush rod 11 is rotatably connected to the pulley 16 and its surface is fixedly connected to the gear 14. One side of the pulley 16 is pressed against the groove on the other side of the outer shell 1 and rolls on it. The surface of the gear 14 and the side opposite to the pulley 16 mesh with the rack 15 fixedly connected to the outer shell 1, so that the brush rod 11 moves and rotates under the constraint of the gear 14 and the pulley 16, thereby driving the bristles 12 on the surface of the brush rod 11 to quickly clean the filter screen 7. When the filter screen is deformed or damaged, it is only necessary to rotate and pull out the buckle 4 to release the dust cover 3. After rotating the dust cover 3, rotate the fixing bracket 6, and pinch the latch 8 to reduce one end of the latch 8 and remove the filter screen 7. Reinstallation is simple: align the snap fastener 8 with the hole on the mounting bracket 6 and press to secure the filter 7 to the bracket 6. The mounting bracket 6 can also be secured via the outer casing 1 and the dustproof plate 3. When cleaning the filter 7, dust falls into the dust box 17 through the ramp at the bottom of the inner surface of the outer casing 1. When the dust box 17 is full, press the pushers 18 on both sides of the dust box 17. The pushers 18 move inward, compressing the spring 19 and causing the arc-shaped clip 20 to disengage from the outer casing 1, allowing the dust box 17 to be removed. Reinstallation is simple: align the pushers 18 and arc-shaped clips 20 on the dust box 17 with their corresponding holes on the outer casing 1 and push them in. The arc-shaped clips 20 will automatically secure the dust box 17 to the outer casing 1.
[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
