[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas, and is the heart of a refrigeration system. Compressors are divided into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc. The compressor sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it by driving a piston through the operation of an electric motor, and then discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption).

[0003] After retrieval, the existing patent (publication number: CN210599425U) discloses a compact screw compressor, including a housing and a unit inside the housing; the housing includes a bottom plate, a rear vertical fixing part and a flip cover, and a hinge structure is arranged between the flip cover and the front side of the bottom plate. The flip cover includes a side edge and a top plate; for the need of a compact design of a screw air compressor, through the flip cover design, it is very convenient to carry out maintenance.

[0004] However, there are still deficiencies in the above structure. When the compact screw compressor is in use, the natural cooling method using a louver window easily allows dust to enter the housing and affect the normal operation of the compressor.

[0005] Therefore, it is necessary to provide a new compact compressor to solve the above technical problems. Content of the Utility Model

The compact compressor includes: an outer shell 1 and a compact compressor 2. A dust-proof mechanism is provided on the outer shell 1, and a shock-absorbing mechanism is provided on the compact compressor 2;

[0025] The dust-proof mechanism includes an L-shaped cover plate 3. The L-shaped cover plate 3 is hinged to the outer shell 1. An installation frame 4 is hinged to the L-shaped cover plate 3. A filter screen 5 is clamped on the installation frame 4. A chuck 6 is fixedly connected to the top surface of the installation frame 4. An installation groove is formed in the L-shaped cover plate 3. A sliding plate 7 is slidably installed in the installation groove. Three return springs 8 are fixedly connected to the top surface of the sliding plate 7, and the tops of the three return springs 8 are fixedly connected to the inner wall of the installation groove. A lifting plate 9 is fixedly connected to one side surface of the sliding plate 7;

[0026] The shock absorption mechanism includes a fixed frame 10, which is fixedly installed on the compact compressor 2. Four rubber pads 11 are fixedly connected to the bottom surface of the fixed frame 10. Spring shock absorbers are fixedly connected to the bottom surfaces of the four rubber pads 11. The bottom end of the spring shock absorber is fixedly connected to a base 12. The bottom surface of the base 12 is fixedly connected to the inner wall of the housing 1. Two sliding platforms 13 are fixedly connected to the top surface of the base 12. Two fixing plates 14 are fixedly connected to the bottom surface of the fixed frame 10.

[0027] As Figure 2 shown, a handle 15 is rotatably connected to the L-shaped cover plate 3. A fixing strip 16 is fixedly connected to the inner wall of the L-shaped cover plate 3. The fixing strip 16 is fixedly connected to the housing 1 by bolts;

[0028] By providing the handle 15, the whole device can be conveniently lifted. By providing the fixing strip 16, the L-shaped cover plate 3 can be fixedly installed on the housing 1.

[0029] As Figure 1 shown, four feet 17 are fixedly connected to the bottom surface of the housing 1. A pressure gauge 18 and a push switch 19 are installed on the housing 1;

[0030] By providing the four feet 17, the whole device can be supported. At the same time, by providing the pressure gauge 18, the internal pressure condition of the compact compressor 2 can be observed.

[0031] As Figure 3 shown, a lifting groove is formed on one side surface of the mounting frame 4. The top surface of the chuck 6 is inclined, and the bottom surface of the sliding plate 7 is adapted to the top surface of the chuck 6.

[0032] By providing the lifting groove, the dust-proof mechanism can be conveniently opened. By providing the adaptation of the bottom surface of the sliding plate 7 to the top surface of the chuck 6, when the dust-proof mechanism is closed, the top surface of the chuck 6 can be in contact with the bottom surface of the sliding plate 7, pushing the sliding plate 7 upward, and then the sliding plate 7 can be rebounded by the return spring 8 to clamp the chuck 6.

[0033] As Figure 4 shown, a ventilation groove is formed on the sliding platform 13. The fixing plate 14 is adapted to the sliding platform 13;

[0034] By providing the ventilation groove on the sliding platform 13, when the fixing plate 14 slides in the sliding platform 13, the air in the sliding platform 13 can be discharged to prevent the phenomenon that the fixing plate 14 does not slide in the sliding platform 13.

[0035] As Figure 4 shown, two limit blocks are fixedly installed on the top surface of the sliding platform 13. Corresponding sliding grooves are formed on both side surfaces of the fixing plate 14 corresponding to the two limit blocks;

[0036] The arrangement of fixedly installing two limit blocks on the top surface of the sliding table 13 can limit the position of the fixing plate 14.

[0037] The working principle of the compact compressor provided by the present utility model is as follows:

[0038] First step: When in use, first place the device in the working area. Through the provided dust-proof mechanism, when the compact compressor 2 operates to generate heat, the installation frame 4 ventilates and cools the interior of the housing 1, and at the same time the filter screen 5 filters the dust in the air to prevent dust from entering the housing 1 and affecting the operation of the compact compressor 2. When there is a large accumulation of dust on the filter screen 5, the staff pulls the lifting plate 9 by hand to slide the sliding plate 7 upward, and at the same time holds the lifting groove on the installation frame 4 to pull out the installation frame 4, and then pulls out the filter screen 5 to clean and replace it;

[0039] Second step: When the compact compressor 2 operates normally and generates vibration, through the provided shock-absorbing mechanism, the rubber pad 11 at the bottom of the fixed frame 10 buffers the vibration of the compact compressor 2. At the same time, when the compact compressor 2 vibrates and generates displacement, the fixing plate 14 can slide within the sliding table 13, and the spring shock absorber buffers and dampens the compact compressor 2, enabling it to operate normally for a long time, extending the service life of the compact compressor 2 and saving costs.
