Description

Technical Field

[0001] This utility model relates to the field of air compressor structure, and in particular to an air compressor door ventilation structure. Background Technology

[0002] Air compressors have air filters, but existing air compressors rely entirely on these filters for filtration. This allows large amounts of debris, lint, and metal shavings to adhere to the air filter, significantly shortening its lifespan and requiring frequent replacement, thus increasing costs. Furthermore, adding existing air filtration devices to the air filter's intake occupies internal space, increasing both size and cost. Therefore, further improvements are needed. Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a structure that occupies less space in the air compressor and can filter the air at the air inlet of the air compressor air filter element.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] An air compressor door ventilation structure includes a door body installed on an air compressor, a lower hollow groove provided on the door body, a main air intake filter communicating with the outside and the inside of the air compressor provided on the lower hollow groove, a middle hollow groove provided on the door body, a secondary air intake filter provided on the middle hollow groove, and a guide plate provided on one side of the secondary air intake filter to guide the filtered air to the air filter element of the air compressor.

[0006] Furthermore, the main air intake filter in this utility model includes a filter screen disposed inside the lower cavity and a louvered grille disposed outside the lower cavity.

[0007] Furthermore, the secondary air intake filter in this utility model includes several mounting slots disposed on the outside of the hollow slot, and a filter plate that can be installed and removed by snap-fit ​​is disposed in the mounting slot.

[0008] Furthermore, the flow guide plate in this utility model is disposed inside the hollow groove, and the flow guide plate includes a plate body and a flow port disposed on the plate body.

[0009] Furthermore, in this utility model, the flow port is directly opposite the air inlet of the air compressor's air filter element.

[0010] In summary, the advantages of this utility model over the prior art are:

[0011] This invention features an openable door on the casing of an air compressor, with a filtration function integrated into it. Air is filtered before it enters the air compressor's air filter, reducing most impurities, lint, and metal filings in the air. This reduces the filtration load on the air filter, preventing premature shortening of its lifespan. Furthermore, the air filtration is conveniently located on the door for easy access and maintenance without occupying internal space. Attached Figure Description

[0013] Figure 2 This is the second perspective view of the present invention;

[0014] Figure 3 This is a planar exploded view of the present invention. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0016] like Figures 1 to 3 The present invention preferably provides a ventilation structure for an air compressor door, including a door body 1 installed on the air compressor. A lower slot 11 is provided on the door body 1, and a main intake filter 2 communicating with the outside and the inside of the air compressor is provided on the lower slot 11. A middle slot 12 is also provided on the door body 1, and a secondary intake filter 3 is provided on the middle slot 12. A guide plate 4 guiding filtered air to the air compressor air filter element is provided on one side of the secondary intake filter 3. The door body is installed on the outer casing of the air compressor and can be opened and closed. The lower and middle slots on the door body are used to install the main intake filter and the secondary intake filter. The main intake filter is mainly used for the overall external air intake of the air compressor, and the secondary intake filter is mainly used for the front-end filtration of the air compressor air filter element. The front-end filtration of the air compressor air filter element is guided to the front air intake of the air filter element by the guide plate, which has a positioning function.

[0017] The main intake filter 2 described in this invention includes a filter screen 21 disposed inside the lower cavity 11 and a louvered grille 22 disposed outside the lower cavity 11. The louvered grille prevents foreign objects from entering the filter screen and provides protection, while the filter screen filters out fine impurities, reducing the amount that enters the air compressor body.

[0018] The secondary air intake filter 3 of this invention includes several mounting slots 31 disposed on the outside of the hollow groove 12. Each mounting slot 31 contains a filter plate 32 that can be installed and removed via snap-fit. The mounting slots are square openings, and the filter plates are installed within them via snap-fit, facilitating installation, removal, replacement, and cleaning. The filter plates can isolate most debris, lint, and metal filings, ensuring cleaner air entering the air intake plate and reducing the filtration pressure on the air filter element.

[0019] The flow guide plate 4 described in this invention is disposed inside the hollow groove 12. The flow guide plate 4 includes a plate body 41 and a flow port 42 disposed on the plate body 41. The plate body blocks all other places except the flow port, allowing air to enter only through the flow port, which is directly opposite the air filter of the air compressor. Therefore, the function of the flow guide plate is to guide the air into the designated location.

[0020] In this invention, the flow port 42 is directly opposite the air inlet of the air compressor's air filter element. Air filters are a common existing technology located inside air compressors and have a specific air inlet position. Therefore, in harsh workshop environments, there are many impurities, lint, and iron filings in the air intake. If all of these adhere to the air filter element's air inlet, its service life will be reduced.

[0021] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
