Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and more specifically, to an air compressor with an easy-to-replace filter element. Background Technology

[0002] An air compressor is a key power device that converts mechanical energy into gas pressure energy. The core function of an air compressor is to compress and store outside air, providing a stable high-pressure air source for various pneumatic tools and equipment.

[0003] Currently, existing air compressors have the following problems when in use: (1) Traditional air compressors lack effective dust prevention measures during the intake process. The air contains a large amount of dust, particulate matter and other impurities. These impurities will enter the piston cylinder during the intake process, increasing frictional resistance, causing piston wear to intensify and reducing service life. At the same time, if a single filter mechanism is set up, the machine will stop when the filter element is replaced, resulting in the end of use. Also, when the filter element is blocked during external use, the air compressor will not be able to be used normally. (2) In the existing technology, the auxiliary functions of air compressors are relatively simple, and most of them are not equipped with a special storage structure. The pipes and other parts used with the air compressor need to be carried separately, making it difficult to store the accessories. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes an air compressor with easy filter replacement, including an air tank 1. A piston cylinder 2 is fixedly connected to the upper end of the air tank 1. An air inlet pipe 3 is fixedly connected to the air inlet end of the piston cylinder 2. A three-way pipe 4 is fixedly connected to the end of the air inlet pipe 3. Valves 5 are fixedly connected to both input ends of the three-way pipe 4. A filter cartridge 6 is threadedly connected to the outer end of the valve 5. A set of air inlet holes 7 are evenly opened on the outer peripheral side wall of the filter cartridge 6. A first filter element 8 is fixedly connected to the inner side wall of the filter cartridge 6. A second filter element 9 is fixedly connected inside the first filter element 8. A power mechanism 10 is provided on the air tank 1, and a storage mechanism 11 is provided at the bottom of the air tank 1. After air enters the filter cartridge 6, it passes through the filter cartridge 6 in sequence. The dual filtration of the first filter element 8 and the second filter element 9 removes dust and other impurities from the air. The filtered clean air enters the intake pipe 3 through the valve 5 and the three-way pipe 4, and then enters the piston cylinder 2. During use, the front valve 5 is opened and the rear valve 5 is closed, or the front valve 5 is closed and the rear valve 5 is opened. When the filter element becomes clogged, there is no need to stop the machine to replace it, ensuring continuous normal use. It is also convenient for outdoor use when there is no replaceable filter element. In this case, another filter element can be directly switched to ensure the normal operation of the air compressor. It is worth noting that the piston cylinder 2 and its internal components are existing technologies and will not be described in detail here.

[0018] In this embodiment, like Figure 1 and Figure 6 As shown, the power mechanism 10 includes a driven pulley 1001 fixed on the input end of the piston cylinder 2. A bearing seat 1002 is fixedly connected to the upper end face of the air tank 1. A motor 1003 is fixedly connected to the bearing seat 1002. A driving pulley 1004 is fixedly connected to the driving end of the motor 1003. The driving pulley 1004 is connected to the driven pulley 1001 via a belt 1005. After the motor 1003 is started, its driving end drives the driving pulley 1004 to rotate. The driving pulley 1004 drives the driven pulley 1001 to rotate via the belt 1005. The driven pulley 1001 drives the input end of the piston cylinder 2 to move, thereby realizing the reciprocating motion of the piston in the piston cylinder 2 and completing the air compression process.

[0019] like Figure 1 , Figure 4 and Figure 5As shown, the storage mechanism 11 includes a support frame 1101 fixed to the bottom of the gas tank 1. A storage drawer 1102 is slidably connected inside the support frame 1101. A strip-shaped opening 1103 is provided on one side wall of the support frame 1101. A movable block 1104 is provided inside the strip-shaped opening 1103. The inner end of the movable block 1104 is fixedly connected to the storage drawer 1102. A handle 1105 is fixedly connected to the outer end of the storage drawer 1102. A mounting shaft 1106 is inserted into the top of the outer end of the storage drawer 1102. The outer end of the mounting shaft 1106 is fixed... A knob 1107 is connected to the mounting shaft 1106, and a clip 1108 is fitted onto the mounting shaft 1106. A nut 1109 is located on the side of the clip 1108 away from the knob 1107, and the nut 1109 is threadedly connected to the mounting shaft 1106. A protrusion 1110 is fixedly connected inside the clip 1108. An insertion slot 1111 that mates with the protrusion 1110 is provided on the mounting shaft 1106. Two limiting blocks 1112 that mate with the clip 1108 are fixedly connected to the inner wall of the storage drawer 1102. To secure the storage drawer 1102, the clip 1108 is... Figure 4 The storage drawer 1102 is pushed into the support frame 1101. Then, the knob 1107 is turned to rotate the mounting shaft 1106, which in turn rotates the card 1108 and the protrusion 1110, causing the card 1108 to contact another limiting block 1112. At this time, the card 1108 is in a vertical state, thus locking the storage drawer 1102. When it is necessary to open the storage drawer 1102, the knob 1107 is turned to rotate the mounting shaft 1106, which in turn rotates the card 1108 and the protrusion 1110, causing the card 1108 to rotate to... Figure 5 Once the device is in the correct position, pull the handle 1105 to remove the storage drawer 1102, making it convenient to place accessories in the storage drawer 1102.

[0020] To further explain, such as Figure 1 and Figure 2 As shown, two fixed plates 12 are symmetrically and fixedly connected to one end of the lower end face of the air tank 1. A rotating rod 13 is rotatably connected between the two fixed plates 12. Rollers 14 are fixedly connected to both ends of the rotating rod 13. A support foot 15 is fixedly connected to the other end of the lower end face of the air tank 1. When the air compressor needs to be moved, the air compressor is lifted and tilted, and then rolled on the ground by the rollers 14 to realize the movement of the equipment. When the equipment is moved to the designated position, the support foot 15 contacts the ground, which plays a role in stabilizing and supporting the equipment and preventing the equipment from rolling.

[0021] like Figure 1 and Figure 2As shown, a support plate 17 is provided on the rear side of the air tank 1. A set of support blocks 18 are evenly fixedly connected to the lower end face of the support plate 17. The bottom end of the support block 18 is fixedly connected to the air tank 1. A protective cover 19 is fixedly connected to the upper end face of the support plate 17 by bolts. The protective cover 19 can protect the rear part of the equipment structure, prevent collisions with external objects, and improve the safety of the air compressor.

[0022] In actual products, such as Figure 1 and Figure 2 As shown, handles 16 are fixedly connected to both ends of the upper surface of the gas tank 1. The corners of the handles 16 are rounded. Operators can move or transport the air compressor by holding the handles 16. The rounded corner design can prevent operators from being scratched by the corners of the handles 16, thus improving the safety and comfort of use.

[0023] Specifically, when using this air compressor with easy-to-replace filter element: First, open the front valve 5 and close the rear valve 5. When the air compressor is working, air will enter the filter cartridge 6, and then pass through the first filter element 8 and the second filter element 9 for double filtration. The filtered air enters the intake pipe 3 through the valve 5 and the three-way pipe 4, and then enters the piston cylinder 2. When the filter element is clogged and needs to be replaced, open the rear valve 5 and then close the front valve 5. Then remove the clogged filter cartridge 6 and replace it with a new filter cartridge 6 assembly. When storing or retrieving items, turn the knob 1107 to rotate the mounting shaft 1106, which in turn drives the card 1108 and the protrusion 1110 to rotate, causing the card 1108 to rotate to... Figure 5 In the current state, pull handle 1105 to remove storage drawer 1102, then place or remove accessories from storage drawer 1102. Push storage drawer 1102 into support frame 1101, then turn knob 1107 to rotate mounting shaft 1106, which in turn rotates card 1108 and protrusion 1110, causing card 1108 to contact another limiting block 1112. At this time, card 1108 is in a vertical position, thus locking storage drawer 1102. The closed state is as follows: Figure 1 As shown.

[0024] All technical features in this embodiment can be freely combined according to actual needs.

[0025] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
