[0023] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0024] Please see Figure 1-5 This patent provides a technical solution: an energy-saving compressor housing, including an upper cover 1 and a lower cover 2, the upper cover 1 and the lower cover 2 are connected to form the compressor housing, a stationary plate 6 is installed inside the housing, an eccentric shaft 8 extends out from the lower cover 2, a moving plate 5 is installed on the eccentric shaft 8, the moving plate 5 is placed inside the stationary plate 6, an anti-rotation mechanism 7 is installed inside the housing, an air inlet 9 is opened on the upper cover 1, an air outlet 10 is opened in the center of the upper cover 1, a filter element 11 is installed inside the air inlet 9, the filter element 11 is made of air filter cotton material, the outer part is made of metal material, and is installed in the air inlet 9 on the housing by bolting or welding, the filter element 11 is inclined at thirty degrees to the outer periphery of the upper cover 1;
[0025] The scroll compressor consists of an upper cover 1, a lower cover 2, a moving disc 5, a stationary disc 6, an anti-rotation mechanism 7, an eccentric shaft 8, an inlet 9, and an outlet 10. Its working principle is to compress gas through the relative motion of the moving and stationary scroll discs. The scroll compressor comprises a fixed involute scroll disc and an eccentrically rotating involute scroll disc. During the intake, compression, and exhaust processes, the stationary disc is fixed to the frame, while the moving disc is driven by the eccentric shaft and rotates in a small-radius plane around the center of the stationary disc's base circle. Gas is drawn into the periphery of the stationary disc through an air filter. As the eccentric shaft rotates, the gas in the crescent-shaped compression chamber formed by the engagement of the moving and stationary discs is gradually compressed and then discharged through the axial hole at the center of the stationary disc.
[0026] Scroll compressors are highly efficient and energy-saving: Due to the design of scroll compressors, the temperature change of gas is small during the compression process, resulting in high energy efficiency.
[0027] Low noise: Due to its smooth operation, the scroll compressor has a low noise level.
[0028] Simple structure: The design of the moving and stationary scroll plates makes the overall structure relatively simple and easy to maintain.
[0029] High reliability: Fewer moving parts and fewer components improve overall reliability and lifespan;
[0030] A filter element 11 is installed inside the air inlet 9 on the compressor housing. When the compressor is working, the gas is compressed by the relative movement of the moving and stationary scroll plates. The filter element 11 inside the air inlet 9 on the housing can filter the air entering the compressor, prevent impurities from entering the compressor housing, and prevent external impurities from causing friction and collision between the moving and stationary scroll plates, thereby avoiding damage to the compressor.
[0031] An air inlet 9 has a discharge port, and a discharge pipe 15 is installed inside the discharge port. The discharge pipe 15 is arranged parallel to the filter element 11. An internal thread is provided at the end of the discharge pipe 15. A threaded cap 16 is fitted inside the discharge pipe 15. A hanging rod 17 is installed on the threaded cap 16. The hanging rod 17 extends into the discharge pipe 15. A rubber ring 18 is fitted over the threaded cap 16. The rubber ring 18 is made of fluororubber and is pressed against the end of the discharge pipe 15.
[0032] When the compressor is working, the threaded cover 16 is screwed into the discharge pipe 15, and the rubber ring 18 can seal the gap between the threaded cover 16 and the discharge pipe 15. When the compressor stops working, the threaded cover 16 is screwed off, and the impurities filtered on the surface of the filter element 11 are scraped into the discharge pipe 15 and discharged through the hanging rod 17 on the threaded cover 16.
[0033] The upper cover 1 and the lower cover 2 are connected by a connecting structure 4. There are no fewer than four connecting structures 4, which are distributed in a ring at equal intervals between the upper cover 1 and the lower cover 2.
[0034] The connecting structure 4 includes a U-shaped frame 401, a threaded rod 402, a connector 403, a U-shaped groove 404, and a nut 405;
[0035] U-shaped frame 401 is installed on the upper cover 1, connector 403 is installed on the lower cover 2, U-shaped groove 404 is opened on connector 403, threaded rod 402 is rotatably installed in U-shaped frame 401 through pin, threaded rod 402 passes through U-shaped groove 404, and nut 405 is sleeved on threaded rod 402.
[0036] When installing the upper cover 1 and the lower cover 2, the threaded rod 402 rotates downward on the U-shaped frame 401 through the pin and is engaged in the U-shaped groove 404 on the connector 403. The nut 405 is screwed onto the threaded rod 402 and pressed against the connector 403 by an external wrench, so that the upper cover 1 and the lower cover 2 are assembled to form the compressor housing. The one-piece connection method replaces the current separate bolt and nut assembly, avoiding the inconvenience of assembly caused by missing parts.
[0037] An annular groove 3 is provided inside the upper cover 1, and a sealing gasket 12 is placed inside the annular groove 3. The sealing gasket 12 is made of fluororubber and rests on the lower cover 2. An annular cavity 13 is provided inside the sealing gasket 12, and an annular elastic element 14 is installed inside the annular cavity 13. The annular elastic element 14 is made of steel sheet. The annular elastic element 14 in the annular cavity 13 enhances the resilience of the sealing gasket 12. When the upper cover 1 and the lower cover 2 are installed, the sealing gasket 12 is placed in the annular groove 3, and the sealing gasket 12 seals the gap between the upper cover 1 and the lower cover 2.
[0038] When using this energy-saving compressor housing, firstly, during the installation of the upper cover 1 and lower cover 2, place the sealing gasket 12 in the annular groove 3, and allow the threaded rod 402 to rotate downwards on the U-shaped bracket 401 via the pin, engaging into the U-shaped groove 404 on the connector 403. Use an external wrench to screw the nut 405 onto the threaded rod 402, securing it against the connector 403, thus assembling the upper cover 1 and lower cover 2 to form the compressor housing. The sealing gasket 12 seals the gap between the upper cover 1 and lower cover 2. Install the filter element 11 inside the air inlet 9 on the compressor housing. When the compressor operates, the relative movement of the moving and stationary scroll plates... The compressor compresses the gas by moving the filter element 11 inside the air inlet 9 on the outer casing. This filter element 11 filters the air entering the compressor, preventing impurities from entering the compressor casing and avoiding the impact of external impurities on the friction and collision between the moving and stationary discs, thus preventing damage to the compressor. When the compressor is working, the threaded cover 16 is screwed into the discharge pipe 15, and the rubber ring 18 seals the gap between the threaded cover 16 and the discharge pipe 15. When the compressor stops working, the threaded cover 16 is unscrewed, and the impurities filtered by the filter element 11 are scraped into the discharge pipe 15 and discharged through the hanging rod 17 on the threaded cover 16.
