[0002] Compressors are widely used in various fields, among which scroll compressors have been booming in recent years due to their advantages such as energy saving, high efficiency, low noise and small size. The general scroll compressor structure mainly includes an exhaust cover, a compressor housing, a stationary scroll and a movable scroll. The exhaust cover is covered on the compressor housing and the stationary scroll and the movable scroll are clamped in the exhaust cover and the compressor housing. When the compressor is operating, the discharge force and vortex force of the high-pressure gas will cause the exhaust cover and the stationary scroll to move relative to each other, resulting in structural instability. Therefore, many compressor manufacturers will fix a plurality of positioning pins on the stationary scroll to fit with the plurality of positioning holes on the inner side of the exhaust cover to prevent the exhaust cover and the stationary scroll from moving relative to each other.

[0003] However, the use of locating pins will cause difficulties in assembling the static scroll and the exhaust cover because it is difficult to align multiple locating pins with multiple locating holes at the same time. In addition, the machining accuracy requirements for each locating hole on the exhaust cover are quite high. If the hole size and position are slightly deviated, the locating pin cannot be inserted, thereby increasing the machining difficulty and machining cost. Utility Model Content

[0032] The detailed description and technical contents of the present invention will be described below with reference to the accompanying drawings. However, the accompanying drawings are only for illustrative purposes and are not intended to limit the present invention.

[0033] The utility model provides a compressor structure, please refer to Figures 1 to 6 As shown, it mainly includes an exhaust cover 10, a fixed scroll 20 and a filter device 30. It should be noted that the compressor structure of the utility model also includes at least the necessary components of the compressor such as the compressor housing and the movable scroll. Since these components have no direct relationship with the main technical content of the utility model, and these components are also technologies and configurations well known to those with ordinary knowledge in the field, they are not shown in the drawings for the convenience of understanding and reading, but are not used to limit the compressor structure of the utility model.

[0034] Please read first Figures 1 to 4As shown, the exhaust cover 10 is a roughly circular cover body, and its bottom has a connecting surface 11 for fitting to the aforementioned compressor housing for locking, thereby facilitating the removal or installation of components such as the fixed scroll 20 and the aforementioned movable scroll between the two. The exhaust cover 10 has a receiving groove 12, a first positioning groove 13 and an oil return exhaust pipe 14. The receiving groove 12 is formed by the connection surface 11 being recessed inward to form a receiving portion 121. The first positioning groove 13 is formed in the receiving portion 121, and the setting direction of the first positioning groove 13 is parallel to the setting direction of the receiving groove 12. In other words, the receiving groove 12 and the first positioning groove 13 are both recessed toward the interior of the exhaust cover 10, so the first positioning groove 13 is located in the receiving groove 12. The first positioning groove 13 is connected to the oil return exhaust pipe 14.

[0035] The fixed scroll 20 is accommodated in the receiving groove 12 of the exhaust cover 10. Specifically, the receiving portion 121 of the exhaust cover 10 surrounds the outer edge of the fixed scroll 20, thereby longitudinally and laterally restricting the fixed scroll 20. The fixed scroll 20 has a second positioning groove 21 and an oil return pipeline 22. The position of the second positioning groove 21 corresponds to the position of the first positioning groove 13, and the second positioning groove 21 is connected to the first positioning groove 13 and the oil return pipeline 22. Specifically, the setting direction of the second positioning groove 21 is parallel and coaxial to the setting direction of the first positioning groove 13. Accordingly, the oil return exhaust pipeline 14 is connected to the oil return pipeline 22 through the first positioning groove 13 and the second positioning groove 21 in sequence. Therefore, when the high-pressure gas compressed by the compressor structure is exhausted from the oil return exhaust pipeline 14, the lubricating oil carried can be returned to the compression chamber (not shown) through the first positioning groove 13, the second positioning groove 21 and the oil return pipeline 22 for recycling.

[0036] Please read next Figure 4 and Figure 5As shown, the filter device 30 has a first positioning portion 301 and a second positioning portion 302. The first positioning portion 301 of the filter device 30 is fixed in the first positioning groove 13 of the exhaust cover 10, and the second positioning portion 302 of the filter device 30 is fixed in the second positioning groove 21 of the fixed scroll 20. The filter device 30 is used to filter impurities in the lubricating oil flowing between the first positioning groove 13 and the second positioning groove 21, so as to ensure that the recovered lubricating oil can provide a good lubrication effect when the compressor is actuated. The volume of the first positioning portion 301 is greater than the volume of the second positioning portion 302. In this way, since the first positioning portion 301 and the second positioning portion 302 of the filter device 30 are respectively fixed in the first positioning groove 13 of the exhaust cover 10 and the second positioning groove 21 of the fixed scroll 20, the filter device 30 can circumferentially limit the fixed scroll 20 so that it cannot rotate relative to the exhaust cover 10, thereby achieving the positioning effect of both filtering and preventing the fixed scroll 20 from rotating relative to the exhaust cover 10. In addition, since the exhaust cover 10 and the static scroll 20 omit the positioning holes used in the traditional positioning pin arrangement, and only require the first positioning groove 13 and the second positioning groove 21 to be respectively arranged on the exhaust cover 10 and the static scroll 20, the processing difficulty and processing cost of the exhaust cover 10 and the static scroll 20 can be effectively reduced.

[0037] Further explanation: the volume of the first positioning portion 301 of the utility model is about 1.1 to 4 times the volume of the second positioning portion 302, so that the exhaust cover 10 and the static vortex 20 can be effectively positioned to prevent the circumferential rotation between the two, and the filter device 30 can be easily disassembled or installed. In this embodiment, after multiple experiments and tests, the volume of the first positioning portion 301 is preferably about 2 to 3 times the volume of the second positioning portion 302, so that the filter device 30 can be effectively fixed in the static vortex 20 and is not easy to fall off, and the positioning effect between the exhaust cover 10 and the static vortex 20 can be effectively ensured to prevent the circumferential rotation between the two, and the filter device 30 can be easily disassembled or installed.

[0038] See also Figures 1 to 5As shown, in this embodiment, the filter device 30 is cylindrical, but the utility model is not limited to this. For example, the filter device 30 can also be triangular, rectangular, polygonal or irregular. Specifically, the filter device 30 in this embodiment mainly includes a filter body 31 in a cylindrical shape and a filter element (not shown) arranged in the filter body 31. The filter element can be a filter screen made of metal, cotton, glass fiber or chemical fiber (such as polypropylene fiber, polypropylene, polyester fiber, non-woven fabric), and the utility model is not particularly limited to this. The filter body 31 has the aforementioned first positioning portion 301 and the second positioning portion 302, so the outer diameter of the first positioning portion 301 is the same as the outer diameter of the second positioning portion 302. The depth of the first positioning groove 13 of the utility model is approximately 1.1 to 5 times the depth of the second positioning groove 21, so that the exhaust cover 10 and the static scroll 20 can effectively play a good positioning effect to prevent the circumferential rotation between the two, and make the filter device 30 easy to disassemble or install. In this embodiment, after many experiments and tests, the depth of the first positioning groove 13 is preferably approximately 2 to 4 times the depth of the second positioning groove 21. This can effectively fix the filter device 30 in the static vortex 20 and prevent it from falling off. It can also effectively ensure the positioning effect between the exhaust cover 10 and the static vortex 20 to prevent circumferential rotation between the two, while allowing the filter device 30 to be easily disassembled or installed.

[0039] In addition, the filter device 30 in this embodiment also includes a first rubber ring 32 and a second rubber ring 33. The outer wall of the first positioning portion 301 has a first groove 301A, and the outer wall of the second positioning portion 302 has a second groove 302A. In this embodiment, the first groove 301A and the second groove 302A are respectively located at the two ends of the filter body 31, but the utility model is not limited thereto. The first rubber ring 32 is sleeved in the first groove 301A, and the first rubber ring 32 elastically abuts between the filter body 31 and the exhaust cover 10, thereby effectively ensuring the sealing between the filter body 31 and the exhaust cover 10, and increasing the clamping force between the first positioning portion 301 and the first positioning groove 13. The second rubber ring 33 is sleeved in the second groove 302A, and the second rubber ring 33 elastically abuts between the filter body 31 and the static vortex 20, thereby effectively ensuring the sealing between the filter body 31 and the static vortex 20, and increasing the clamping force between the second positioning portion 302 and the second positioning groove 21. In addition, since the first rubber ring 32 and the second rubber ring 33 are provided to increase the clamping force, the first positioning groove 13 of the exhaust cover 10 and the second positioning groove 21 of the static vortex disc 20 do not need to be clamped with the first positioning portion 301 and the second positioning portion 302 of the filter device 30 by tight fitting, but can maintain a certain tolerance margin. This not only makes it convenient for users to install or disassemble the filter device 30, but also reduces the processing difficulty and processing cost of the first positioning groove 13 and the second positioning groove 21.

[0040] See also Figure 1 , Figure 2 and Figure 4 As shown, the compressor structure of the utility model further includes a sealing rubber ring 40. The sealing rubber ring 40 is sleeved on the static scroll 20 and elastically clamped between the static scroll 20 and the exhaust cover 10, thereby effectively ensuring the sealing between the static scroll 20 and the exhaust cover 10, and increasing the clamping force between the static scroll 20 and the exhaust cover 10. It is worth noting that the static scroll 20 of the utility model has a positioning protrusion 23 protruding from its main body (not numbered in the figure), and the receiving groove 12 of the exhaust cover 10 is formed with the aforementioned receiving portion 121 and a limiting portion 122 recessed inwardly from the receiving portion 121. The main body of the static scroll 20 is received in the receiving portion 121 of the receiving groove 12, and the positioning protrusion 23 of the static scroll 20 is clamped in the limiting portion 122 of the exhaust cover 10, so as to effectively enable the exhaust cover 10 to longitudinally and laterally limit the static scroll 20. The sealing rubber ring 40 is sleeved on the positioning protrusion 23 of the fixed scroll 20 , and the sealing rubber ring 40 is elastically clamped between the positioning protrusion 23 of the fixed scroll 20 and the limiting portion 122 of the exhaust cover 10 .

[0041] The compressor structure of the present invention can longitudinally and laterally restrict the static scroll 20 by accommodating the static scroll 20 in the receiving groove 12 of the exhaust cover 10, and by respectively clamping the first positioning portion 301 and the second positioning portion 302 of the filter device 30 in the first positioning groove 13 of the exhaust cover 10 and the second positioning groove 21 of the static scroll 20, the filter device 30 can simultaneously have the positioning effects of filtering and preventing the static scroll 20 from rotating relative to the exhaust cover 10, and effectively reduce the processing difficulty and processing cost of the exhaust cover 10 and the static scroll 20.

[0042] In summary, the above disclosure of the utility model is to enable those with ordinary knowledge in the field to clearly understand the technical content of the utility model and implement it accordingly, and is not intended to limit the scope of patent protection of the utility model. In addition, the utility model can of course have other unlisted embodiments. Without departing from the spirit and essence of the utility model, technicians familiar with the field should be able to evolve various corresponding changes and deformations based on the utility model, but these corresponding changes and deformations should all fall within the scope of protection of the patent applied for the utility model.
