DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The utility model provides Figure 1-5 An air compressor shown includes a body 1, one side of which is provided with a vent, the vent being provided to facilitate air circulation inside the air compressor to ensure that the internal components are not damaged due to high temperature;

[0033] The outside of the vent is fixedly connected with a fixing frame 2, which is a square tube frame with two ends interconnected, so that the air inside the air compressor can flow from one end to the other end until it is discharged. The inside of the fixing frame 2 is provided with a guiding filter mechanism 3, which includes: a partition 31, a filter plate 32, a direction adjustment component 33 and a clamping component 34. The partition 31 is fixedly connected to the inner wall of the fixing frame 2, and the partition 31 is located in the middle of the inside of the fixing frame 2, so that the inside of the fixing frame 2 can be divided into two cavities; the side of the partition 31 opposite to the inner wall of the fixing machine is provided with a mounting groove, and the filter plate 32 is slidably connected with the inner cavity of the mounting groove, and a filter plate 32 is provided inside the two cavities, so that one of the filter plates 32 can be cleaned and replaced when the other filter plate 32 is in use; the direction adjustment component 33 is arranged inside the fixing frame 2 for adjusting the flow direction of the air; a plurality of clamping grooves are arranged inside the partition 31, and the clamping component 34 is located inside the clamping groove for fixing the position of the filter plate 32.

[0034] The direction adjustment component 33 includes: an adjustment plate 331, an extrusion plate 332 and a fixed plate 333. The adjustment plate 331 is rotatably connected to the inside of the fixed frame 2 through a rotating shaft. By placing the adjustment plate 331 and the partition 31 in the same middle position, after the adjustment plate 331 is rotated to fit the inner wall of the fixed frame 2, one of the cavities can be closed and only the other cavity can be used; multiple extrusion plates 332 are respectively fixedly connected to both sides of the adjustment plate 331, and the extrusion plates 332 cooperate with the clamping component 34. The setting of the extrusion plates 332 facilitates the state adjustment of the clamping component 34; the fixed plate 333 is fixedly connected to the top of the rotating shaft, and the adjustment plate 331 can be rotated by the fixed plate 333, so as to adjust the flow direction of the internal air. Without affecting the normal use of the air compressor, it can be ensured that dust will not enter the air compressor due to long-term replacement of the filter plate 32, which is convenient for use.

[0035] Furthermore, a through groove is provided at the top of the fixing plate 333, and a plurality of adjustment holes are provided at the top of the fixing frame 2. A fixing pin 4 is slidably inserted and connected to the inner cavity of the through groove. The fixing pin 4 is threadedly inserted and connected to the inner cavity of the adjustment hole. The fixing pin 4 is inserted into the adjustment holes at different positions, so that the adjustment plate 331 can be fixed in different states, so that the adjustment plate 331 can be fixed in position after the adjustment plate 331 changes the air circulation inside the fixing frame 2.

[0036] The clamping assembly 34 includes: a clamping rod 341, a slider 342 and a compression spring 343. The outer wall of the filter plate 32 is provided with a clamping hole. One end of the clamping rod 341 is slidably inserted and connected with the inner cavity of the clamping groove. The other end of the clamping rod 341 is slidably inserted and connected with the inner cavity of the clamping hole. The cross section of the clamping rod 341 is J-shaped. The clamping rod 341 can be used to fix the filter plate 32 in position; the inner wall of the clamping groove is provided with a slide groove. The slider 342 is slidably inserted and connected with the inner cavity of the slide groove. The slider 342 plays a role in limiting the clamping rod 341, so that the clamping The connecting rod 341 can only be displaced by the slider 342; the compression spring 343 is located inside the slide slot, one end of the compression spring 343 is fixedly connected to the slider 342, and the other end of the compression spring 343 is fixedly connected to the inner wall of the slide slot. The compression spring 343 is always in a compressed state, so that the slider 342 can provide a stable elastic force to the clamping rod 341, so that one end of the clamping rod 341 is always in an extended state, and the other end is clamped with the filter plate 32, so that the filter plate 32 can be fixedly installed inside the fixing frame 2;

[0037] Furthermore, a slope is provided at one end of the clamping rod 341, and the clamping rod 341 cooperates with the extrusion plate 332. The extrusion plate 332 squeezes the slope provided by the clamping rod 341, thereby squeezing the clamping rod 341 into the interior of the clamping groove and making the other end of the clamping rod 341 disengage from the clamping hole. Thus, while the adjustment plate 331 blocks the air circulation in the cavity, the filter plate 32 can be released from the fixation, making it easier to clean and replace the filter plate 32.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
