[0002] Air compressors are key equipment in industrial production and are widely used in industries such as equipment manufacturing, automobiles, metallurgy, power, electronics, medical, and textiles. Their normal operation depends on clean intake air quality.

[0003] Traditional air compressors typically employ built-in filter structures, requiring the use of tools to remove multiple fasteners when replacing the filter. This cumbersome and time-consuming process leads to low equipment maintenance efficiency and extended downtime. Therefore, those skilled in the art are dedicated to developing an external air intake filter device for air compressors. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an external air intake filter for an air compressor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An external air intake filter device for an air compressor includes an air compressor body and a mounting frame. A fixed frame is fixedly connected to one side of the air compressor body, and an air intake pipe is disposed inside the fixed frame. A mounting bracket is fixedly connected inside the mounting frame, and a connecting pipe is fixedly connected inside the mounting bracket. A filter box is fixedly connected to one end of the connecting pipe. A slot is provided at the upper end of the filter box, and a filter box is inserted into the slot. U-shaped sealing plates adapted to the filter box are fixedly connected to the lower end and both sides of the filter box. Snap-fit ​​components are fixedly connected to both sides of the mounting frame.

[0007] As a further improvement of this utility model, the snap-fit ​​assembly includes elastic snap-fit ​​plates fixedly connected to both sides of the mounting frame, and a trapezoidal snap-fit ​​block is fixedly connected to one side of the elastic snap-fit ​​plate.

[0008] As a further improvement of this utility model, both sides of the fixed frame are fixedly connected with snap-fit ​​frames, and one side of the snap-fit ​​frame is provided with a snap-fit ​​groove that is adapted to the trapezoidal snap-fit ​​block.

[0009] As a further improvement of this utility model, positioning grooves are fixedly connected to the four corners of the front of the fixed frame, and positioning blocks that are adapted to the positioning grooves are fixedly connected to the four corners of the back of the mounting frame.

[0010] As a further improvement of this utility model, a filter screen is provided inside the filter frame, and a handle is fixedly connected to the upper end of the filter frame.

[0011] As a further improvement of this utility model, a first connecting plate is fixedly connected to the front of the air intake pipe, and a second connecting plate is fixedly connected to the other end of the connecting pipe.

[0012] As a further improvement of this utility model, a sealing gasket is provided on the opposite side of the first connecting plate and the second connecting plate.

[0013] As a further improvement of this utility model, the sealing gasket is made of rubber.

[0014] As a further improvement of this utility model, a control panel is fixedly connected to one side of the front of the air compressor body.

[0015] As a further improvement of this utility model, bases are fixedly connected to the four corners of the lower surface of the air compressor body.

[0016] The device provided by this utility model has the following technical effects:

[0017] By setting up a snap-fit ​​component, the positioning block and positioning groove are designed to quickly and initially align the installation frame and the fixing frame during use, effectively simplifying the installation process. Subsequently, the elastic plate and trapezoidal snap-fit ​​block structure can complete a firm snap-fit ​​fixation by utilizing the elastic deformation of the material itself, making the installation and disassembly of the entire external filter device simple and quick, shortening maintenance time and reducing the burden on operators.

[0018] By setting up a filter frame, the filter frame can be independently installed in the filter box through a simple plug-in method during use. It is also equipped with a dedicated handle, which allows the inspection, cleaning or replacement of the filter screen to be completed independently without disassembling any other main structural components. This not only ensures the high efficiency and stability of the filtration function and simplifies daily maintenance, but also improves the practicality of the equipment and increases the convenience of operation.

[0019] By setting a sealing gasket, the connecting pipe and the air intake pipe achieve end face sealing through the connecting plate with rubber sealing gasket during use, ensuring no leakage at the pipe connection. At the same time, the U-shaped sealing plate set inside the filter box fits tightly with the filter frame, forming an effective sealing barrier, ensuring that all intake air must be filtered by the filter screen, thus providing continuous and reliable protection for the air compressor main unit and effectively extending the service life of the core components.

[0020] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model. Attached Figure Description

[0027] Some exemplary embodiments of the present invention have been described for illustrative purposes. It should be understood that the present invention may be implemented in other ways not specifically shown in the accompanying drawings.

[0028] like Figures 1-3As shown, an external air intake filter device for an air compressor includes an air compressor body 1 and a mounting frame 10. A fixing frame 2 is fixedly connected to one side of the air compressor body 1. An air intake pipe 3 is provided inside the fixing frame 2. A mounting bracket 4 is fixedly connected inside the mounting frame 10. A connecting pipe 5 is fixedly connected inside the mounting bracket 4. A filter box 6 is fixedly connected to one end of the connecting pipe 5. A slot 7 is provided at the upper end of the filter box 6. A filter frame 8 is inserted into the slot 7. U-shaped sealing plates 9 that are adapted to the filter frame 8 are fixedly connected to the lower end and both sides of the filter box 6. Snap-fit ​​components are fixedly connected to both sides of the mounting frame 10.

[0029] In this utility model, the snap-fit ​​assembly includes elastic snap-fit ​​plates 11 fixedly connected to both sides of the mounting frame 10. The elastic snap-fit ​​plates 11 can deform when subjected to external force, thereby facilitating snap-fit ​​operation. A trapezoidal snap-fit ​​block 12 is fixedly connected to one side of the elastic snap-fit ​​plate 11. The special shape design of the trapezoidal snap-fit ​​block 12 allows it to better cooperate with the corresponding structure during the snap-fit ​​process, enhancing the stability and firmness of the snap-fit. Snap-fit ​​frames 13 are fixedly connected to both sides of the fixed frame 2. A snap-fit ​​groove 14 adapted to the trapezoidal snap-fit ​​block 12 is opened on one side of the snap-fit ​​frame 13. The size and shape of the snap-fit ​​groove 14 match the trapezoidal snap-fit ​​block 12, and the two can be tightly snapped together, effectively preventing the mounting frame 10 from loosening or falling off during use.

[0030] The four corners of the front of the fixed frame 2 are fixedly connected with positioning grooves 15, and the four corners of the back of the mounting frame 10 are fixedly connected with positioning blocks 16 that are compatible with the positioning grooves 15. The positioning blocks 16 can be smoothly inserted into the positioning grooves 15. Through the cooperation of the two, the mounting frame 10 is accurately positioned, improving installation efficiency and accuracy. The filter frame 8 is equipped with a filter screen 17 inside. The filter screen 17 can effectively intercept dust, particles and other pollutants in the air, ensuring that the air entering the air compressor body 1 is clean. The upper end of the filter frame 8 is fixedly connected with a handle 18. The design of the handle 18 makes it convenient for operators to pick up, install and disassemble the filter frame 8.

[0031] The front end of the intake pipe 3 is fixedly connected to a first connecting plate 19, and the other end of the connecting pipe 5 is fixedly connected to a second connecting plate 20. The second connecting plate 20 corresponds to the first connecting plate 19, and the two together form a complete connection structure to ensure that the intake pipe 3 and the connecting pipe 5 can be reliably connected. The opposite sides of the first connecting plate 19 and the second connecting plate 20 are provided with sealing gaskets 21. The sealing gaskets 21 are made of rubber. Rubber has good elasticity and sealing properties and can adapt to a certain degree of pressure change and deformation, thereby achieving a better sealing effect. At the same time, rubber also has a certain degree of wear resistance and corrosion resistance, which can extend the service life of the sealing gaskets 21.

[0032] A control panel 22 is fixedly connected to one side of the front of the air compressor body 1. The control panel 22 is the interface for operators to interact with the air compressor body 1. Through the control panel 22, the operating parameters of the air compressor can be easily set and adjusted, and the working status of the equipment can be monitored. Bases 23 are fixedly connected to the four corners of the lower surface of the air compressor body 1. The bases 23 provide stable support for the air compressor body 1.

[0033] When using this utility model, the positioning block 16 on the back of the mounting frame 10 is aligned with the positioning groove 15 on the front of the fixed frame 2 and inserted to initially position the mounting frame 10 and the fixed frame 2. Subsequently, the trapezoidal snap-fit ​​block 12 on the elastic snap-fit ​​plate 11 is embedded into the snap-fit ​​groove 14 of the snap-fit ​​frame 13. The snap-fit ​​is fixed by the elastic deformation of the elastic snap-fit ​​plate 11, thereby firmly installing the mounting frame 10 on the fixed frame 2. At this time, the second connecting plate 20 at one end of the connecting pipe 5 and the first connecting plate 19 at the end of the air intake pipe 3 are tightly fitted together, and the sealing gasket 21 between the two ensures the sealing of the connection.

[0034] During filtration, air passes through the filter screen 17 in the filter frame 8 for filtration, then enters the intake pipe 3 through the connecting pipe 5, and finally enters the air compressor body 1. The U-shaped sealing plate 9 ensures the seal at the joint between the filter frame 8 and the filter box 6. When maintenance or replacement of the filter screen 17 is required, the filter frame 8 can be pulled upward from the slot 7 of the filter box 6 using the handle 18.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
