Description

Technical Field

[0001] The utility model relates to the technical field of pneumatics, in particular to a shell of a model-level compressor. Background Art

[0002] An air compressor is the core of an air source device, converting the mechanical energy of a prime mover into gas pressure energy. It is the device that generates compressed air pressure. Compressed gas can be used as a power source for pneumatic tools or mechanical transmissions. Compressed gas can also be used for refrigeration and gas separation, where it liquefies through compression, cooling, and expansion. Air compressors can also transport gas.

[0003] Gas often contains some impurities. Some impurities are too large in volume and mass, which will cause wear to the precise structure inside the air compressor, which is not conducive to the operation and life of the air compressor. In view of this, we propose a model-level compressor shell. Utility Model Content

[0007] One end of the block is provided with a block baffle, and when the filter block can be inserted into the housing through the filter opening, the block baffle is exposed to the outside. In addition, the block baffle is provided with a block positioning groove, and a semicircular positioning block is provided inside the housing.

[0008] Furthermore, a front flange is provided at the front end of the casing, and a motor box is provided at the rear side of the front flange.

[0009] Furthermore, an upper machine box is provided on the rear side of the motor box, and a rear flange is provided on the rear side of the upper machine box.

[0022] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0023] See also Figures 1 to 5 This embodiment provides a model-class compressor housing, comprising: a housing A1 and a filter block A2. The filter block A2 can be inserted into the housing A1 through a filter opening 18. When there is too much filter residue on the filter block A2, the filter block A2 can be removed for cleaning and then put back.

[0024] The filter block A2 is provided with a spring 12, a block 13 is provided at the left end of the spring 12, and a filter element 14 is provided in the middle of the filter block A2. When the gas passes through the filter element 14, impurities will be filtered out.

[0025] A block baffle 17 is provided at one end of the block 13. When the filter block A2 can be inserted into the interior of the housing A1 through the filter opening 18, the block baffle 17 is exposed to the outside. In addition, a block positioning groove 16 is provided on the block baffle 17, and a semicircular positioning block 10 is provided inside the housing A1. When the filter block A2 is to be taken out, the block baffle 17 is pressed with a finger. The block baffle 17 will compress the spring 12, thereby separating the semicircular positioning block 10 on the housing A1 from the block positioning groove 16 on the filter block A2. At this time, it can be taken out by hand. After the filter element 14 is cleaned, the block baffle 17 is pressed with a finger, and the filter block A2 is inserted into the filter opening 18. The filter block A2 will be positioned and clamped by the semicircular positioning block 10 and the block positioning groove 16.

[0026] A front flange 1 is provided at the front end of the housing A1 , a motor box 2 is provided at the rear side of the front flange 1 , an upper machine box 3 is provided at the rear side of the motor box 2 , and a rear flange 4 is provided at the rear side of the upper machine box 3 .

[0027] An air inlet 9 is located on the right side of the upper case 3. A pressure gauge 6 and a pressure adjustment knob 5 are located on the left side of the upper case 3. An air outlet 8 is located below and between the pressure gauge 6 and the pressure adjustment knob 5. This allows for monitoring and adjusting the pressure. Turning the pressure adjustment knob 5 counterclockwise decreases the pressure, while turning it clockwise increases it.

[0028] A sealing ring 15 is provided on the outside of the filter element 14 to prevent gas from overflowing and enhance airtightness.

[0029] Working principle: After the air compressor is installed and fixed, start the power supply and the air compressor starts working. The outside gas enters from the air inlet 9, passes through the filter element 14, and the impurities in the gas remain on the filter element 14. Over time, the filter element 14 will be clogged. Therefore, the filter element 14 needs to be cleaned every once in a while. When the filter card block A2 is to be taken out, press the card block baffle 17 with your fingers. The card block baffle 17 will compress the spring 12, so that the semicircular positioning block 10 on the housing A1 is separated from the card block positioning groove 16 on the filter card block A2. At this time, it can be pulled out by hand. When the filter element 14 is cleaned, press the card block baffle 17 with your fingers and insert the filter card block A2 into the filter port 18. The filter card block A2 will rely on the semicircular positioning block 10 and the card block positioning groove 16 for positioning and clamping.

[0030] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
