Among them, the scroll assembly, as the main part of the scroll compressor, usually includes a moving scroll and a fixed scroll. In the related art, there is usually a machining error between the moving scroll and the fixed scroll, and because the moving scroll continuously rotates during the operation of the scroll compressor, it frequently contacts and rubs with the fixed scroll. Therefore, the machining error will cause an axial gap between the moving scroll and the fixed scroll, so a sealing member needs to be provided for axial sealing, but during the movement of the moving scroll and the fixed scroll, the sealing member will be worn and the sealing effect will be affected, thereby causing leakage of the scroll, directly leading to a significant reduction in the energy efficiency of the compressor, failing to achieve the expected compression effect, and reducing the performance of the compressor.

[0029] In the structural design of scroll compressor, the orbiting scroll is eccentrically arranged and meshed with the fixed scroll. When the orbiting scroll is driven to move relative to the fixed scroll, the closed volume formed by the orbiting scroll and the fixed scroll also moves and changes its volume, thereby completing the processes of suction, compression and discharge, and achieving the purpose of compressing gas. However, the orbiting scroll and / or the fixed scroll usually has machining error, such as axial dimension machining error. Thus, when the orbiting scroll moves relative to the fixed scroll, the seal will be worn, thereby causing the leakage of the orbiting scroll and / or the fixed scroll, and reducing the performance of the compressor.

[0030] In order to improve or solve the above technical problems, the present application provides at least the following embodiments.

[0031] Please refer to Figures 1 to 3 , Figure 1 is a cross-sectional structural schematic diagram of an embodiment of the compressor provided by the present application. Figure 2 is Figure 1 a local enlarged view of A in Figure 3 is Figure 1 a local enlarged view of B in

[0032] In some embodiments, as Figures 1 to 3As shown, the present application provides a compressor 100. The compressor 100 comprises a first scroll 10, a second scroll 20 and a first seal 31. The first scroll 10 is provided with a first seal groove 101 on the top of the teeth. The second scroll 20 is engaged with the first scroll 10. The first seal 31 is arranged in the first seal groove 101.

[0033] In some embodiments, the top of the teeth of the second scroll 20 is provided with a second seal groove 201. The compressor 100 further comprises a second seal 32 arranged in the second seal groove 201. In this way, the axial wear of the second scroll 20 and the first scroll 10 can be further reduced.

[0034] In this way, in the structural design of the compressor 100 in the embodiments of the present application, by arranging a seal, such as the first seal 31 and the second seal 32, on at least one of the top of the teeth of the first scroll 10 and the top of the teeth of the second scroll 20, the machining error of the axial size of the second scroll 20 and the first scroll 10 can be compensated to some extent, the axial wear of the second scroll 20 and the first scroll 10 can be reduced, and the axial leakage of the second scroll 20 and / or the first scroll 10 caused by the machining error of the second scroll 20 and / or the first scroll 10 can be reduced. In some embodiments, the compressor 100 can be an oil-free scroll air compressor.

[0035] In some embodiments, the first scroll 10 can be one of a fixed scroll and a moving scroll, and the second scroll 20 can be the other one of the fixed scroll and the moving scroll. As shown, the first scroll 10 is a fixed scroll, and the second scroll 20 is a moving scroll. In addition, those skilled in the art can understand that in some other embodiments, the first scroll 10 can be a moving scroll, and the second scroll 20 can be a fixed scroll. The specific types of the first scroll 10 and the second scroll 20 can be set according to actual needs, and the present application does not make specific limitations. Figure 1

[0036] ​In some embodiments, the first seal 31 and the second seal 32 can be in a strip structure, i.e., the first seal 31 is a first sealing strip and the second seal 32 is a second sealing strip, which can form a sealing strip structure in the compressor 100. It should be understood by those skilled in the art that the first seal 31 and the second seal 32 provided in the embodiments of the present application can also be a sealing strip structure in related art, for example, the material of the first seal 31 and the second seal 32 can be at least one of a resin material such as polytetrafluoroethylene (PTFE), polyether ether ketone (PEEK), polycarbonate (PC), etc. Of course, the material and structure of the first seal 31 and the second seal 32 in the present application are not limited thereto, as long as they can achieve the technical effects of "compensating for the machining error of the axial size of the second scroll 20 and the first scroll 10, and reducing the axial wear of the second scroll 20 and the first scroll 10", which are not specifically limited in the present application.

[0037] Since the material of the first seal 31 and the second seal 32 is usually an elastic material, and the material of the second scroll 20 and the first scroll 10 is usually a metal material, for example, the second scroll 20 and the first scroll 10 can be aluminum alloy scrolls. If the first seal 31 is always in direct contact with the tooth bottom of the second scroll 20 and the second seal 32 is always in direct contact with the tooth bottom of the first scroll 10 during the operation of the compressor, as the working time of the compressor increases, this direct contact between the seal and the tooth bottom of the scroll will cause a certain degree of wear of the seal, which can cause leakage of the scroll.

[0038] In view of this, in order to reduce the occurrence of wear of the seal, in some embodiments, the compressor 100 further comprises a first wear-resistant piece 41 arranged between the first seal 31 and the second scroll 20. That is, in the structural design of the compressor 100 provided in the embodiments of the present application, not only is the first seal 31 arranged at the tooth top of the first scroll 10, but also the first wear-resistant piece 41 is arranged between the first seal 31 and the second scroll 20.

[0039] In this way, in the structural design of the compressor 100 in the embodiments of the present application, by arranging the first seal 31 and the first wear-resistant piece 41 as above, on the one hand, the machining error of the axial size of the second scroll 20 and the first scroll 10 can be compensated to a certain extent; on the other hand, direct contact between the first seal 31 and the tooth bottom of the second scroll 20 can be avoided, and the wear rate of the first seal 31 can be reduced, thereby improving the service life of the first seal 32 and ensuring the performance of the compressor 100.

[0040] In some embodiments, a portion of the first seal 31 is embedded in the first seal groove 101, and another portion of the first seal 31 protrudes from the first seal groove 101, that is, at least part of the first seal 31 can be exposed from the first seal groove 101. Similarly, the second seal 32 is arranged in the second seal groove 201 in a manner similar to the arrangement of the first seal 31 in the first seal groove 101, which will not be described here.

[0041] In some embodiments, as shown in Figure 1 and Figure 2 , the second scroll 20 includes a second scroll tooth 21 and a second base plate 22. The second scroll tooth 21 and the second base plate 22 form a second scroll groove 202 therebetween. The first wear-resistant piece 41 is arranged in the second scroll groove 202, and the first wear-resistant piece 41 abuts against the second base plate 22, that is, the first wear-resistant piece 41 abuts against the bottom of the second scroll groove 202; part of the first scroll 10 is arranged in the second scroll groove 202, that is, the first scroll tooth of the first scroll 10 is arranged in the second scroll groove 202.

[0042] In some embodiments, a gap is provided between the first wear-resistant piece 41 and the second scroll tooth 21. Specifically, a gap is left between the first wear-resistant piece 41 and the tooth side surface of the second scroll tooth 21. That is, the projection area of the first wear-resistant piece 41 on the bottom of the second scroll groove 202 is smaller than the area of the bottom of the second scroll groove 202. It should be noted that in some other embodiments, the first wear-resistant piece 41 and the tooth side surface of the second scroll tooth 21 can also not have a gap, which is not limited here.

[0043] In some embodiments, the second scroll groove 202 and the first wear-resistant piece 41 respectively extend along a spiral line, and the length of the first wear-resistant piece 41 in the extension direction is smaller than the length of the second scroll groove 202 in the extension direction.

[0044] In some embodiments, the first scroll 10 is provided with a first scroll line, the first seal 31 extends along the first scroll line, and the extension length of the first seal 31 is smaller than the extension length of the first wear-resistant piece 41.

[0045] Therefore, during the movement of the second scroll 20 relative to the first scroll 10, the projection of the movement trajectory of the first seal 31 on the first plane X-Y falls within the projection of the first wear-resistant piece 41 on the first plane X-Y. The first plane X-Y is substantially parallel to the radial direction Y of the first scroll 10. In this way, it can be ensured that the movement trajectory of the first seal 31 can always be covered by the first wear-resistant piece 41, so as to avoid direct contact between the first seal 31 and the bottom of the second scroll tooth 21, effectively reducing the wear rate of the first seal 31.

[0046] In some embodiments, the second scroll 20 is provided with a gas hole in communication with the second scroll groove 202, the gas hole being located at one end of the second scroll groove 202 along the extending direction. The first wear-resistant part 41 does not cover the gas hole.

[0047] In some embodiments, the gas hole includes an exhaust hole 50 and / or an air intake hole 60. The air intake hole 60 is located at the periphery of the second scroll 20, and external air can enter the compressor 100 through the air intake hole 60. The exhaust hole 50 is located at the center of the second scroll 20. By arranging the first wear-resistant part 41 not to cover the gas hole, the first wear-resistant part 41 can be connected to the passage edge of the exhaust hole 50 and the passage edge of the air intake hole 60.

[0048] Similarly, in some embodiments, as shown in Figure 1 and Figure 3 , the first scroll 10 includes a first scroll tooth 11 and a first base plate 12 connected together. The first scroll tooth 11 and the first base plate 12 enclose the first scroll groove 102.

[0049] In some embodiments, the compressor 100 can further include a second wear-resistant part 42 arranged between the second seal 32 and the first scroll 10. The first wear-resistant part 41 is arranged in the first scroll groove 102, and the second scroll 20 is partially arranged in the first scroll groove 102. It can be understood that the structure and arrangement of the second wear-resistant part 42 are basically similar to those of the first wear-resistant part 41. Specifically, the second wear-resistant part 42 can abut the first base plate 12. A gap is provided between the second wear-resistant part 42 and the first scroll tooth 11, for example, a gap is left between the second wear-resistant part 42 and the tooth side surface of the first scroll tooth 11. That is, the second wear-resistant part 42 can not occupy the tooth bottom of the first base plate 12 or the first scroll tooth 11. Similarly, the second wear-resistant part 42 and the tooth side surface of the first scroll tooth 11 can also not have a gap, that is, the second wear-resistant part 42 can occupy the tooth bottom of the first base plate 12 or the first scroll tooth 11. Other contents not specifically described about the second wear-resistant part 42 can also be further referred to the related contents of the first wear-resistant part 41.

[0050] In some embodiments, the first scroll groove 102 and the second wear-resistant part 42 respectively extend along a spiral line, and the length of the second wear-resistant part 42 along the extending direction is less than the length of the first scroll groove 102 along the extending direction.

[0051] In some embodiments, the first scroll 10 is provided with a second scroll line, and the second seal 32 extends along the second scroll line. The extending length of the second seal 32 is less than the extending length of the second wear-resistant part 42.

[0052] Therefore, during the movement of the second scroll 20 relative to the first scroll 10, the movement track of the second seal 32 can be ensured to be covered by the second wear-resistant piece 42 at all times to avoid direct contact between the second seal 32 and the tooth bottom of the first scroll tooth 11, effectively reducing the wear rate of the second seal 32.

[0053] It should be noted that in the description herein, the tooth top of the first scroll tooth 11 is the top surface of the first scroll tooth 11, which can also be referred to as the first scroll tooth top 112; the tooth bottom of the first scroll tooth 11 is the groove bottom of the spiral groove formed by the first scroll tooth 11, which can also be referred to as the first scroll tooth bottom 111, and the side surface of the first scroll tooth 11 can also be referred to as the first scroll tooth side surface 113, as shown in FIG. 1 and FIG. 2. Figure 2 and Figure 3 As shown, the naming of the elements can be interchangeable. Similarly, the tooth top of the second scroll tooth 21 is the top surface of the second scroll tooth 21, which can also be referred to as the second scroll tooth top 212; the tooth bottom of the second scroll tooth 21 is the groove bottom of the spiral groove formed by the second scroll tooth 21, which can also be referred to as the second scroll tooth bottom 211; and the side surface of the second scroll tooth 21 can also be referred to as the second scroll tooth side surface 213, as shown in FIG. 3 and FIG. 4. Figure 2 and Figure 3 As shown.

[0054] In some embodiments, the first wear-resistant piece 41 or the second wear-resistant piece 42 can be a sheet structure, for example, the first wear-resistant piece 41 or the second wear-resistant piece 42 can be a wear-resistant pad or a wear-resistant sheet. The material of the first wear-resistant piece 41 or the second wear-resistant piece 42 can be a metal material, for example, high manganese steel, alloy steel (including high chromium cast iron, low chromium cast iron), hard alloy (including tungsten carbide, chromium carbide, etc.), and other metal materials with excellent wear resistance. In this way, by setting the material of the first wear-resistant piece 41 and the second wear-resistant piece 42 to be the metal material as described above, the wear resistance of the first wear-resistant piece 41 and the second wear-resistant piece 42 can be effectively improved, and the service life of the first wear-resistant piece 41 and the second wear-resistant piece 42 can be further improved. That is, the first wear-resistant piece 41 and the second wear-resistant piece 42 in the embodiments of the present application themselves have excellent wear resistance, and the friction between them and the seal can be reduced, thereby reducing the wear of the seal.

[0055] In some embodiments, the first wear-resistant piece 41 can be detachably installed between the first seal 31 and the tooth bottom of the second scroll tooth 21, and the second wear-resistant piece 42 can be detachably installed between the second seal 32 and the tooth bottom of the first scroll tooth 11. Therefore, when it is necessary to replace the old first wear-resistant piece 41 with a new first wear-resistant piece 41, the old first wear-resistant piece 41 can be directly disassembled, and the new first wear-resistant piece 41 can be directly assembled on the tooth bottom of the second scroll tooth 21. Similarly, the replacement process of the old second wear-resistant piece 42 is similar. In this way, the replacement operation is simplified, and the convenience of operation is improved.

[0056] Referring to Figure 4 and Figure 5 and in combination with Figure 2 and Figure 3 , Figure 4 is Figure 1 a plan view of the first wear-resistant piece in the embodiment shown. Figure 5 is Figure 1 a plan view of the second wear-resistant piece in the embodiment shown.

[0057] In some embodiments, as shown in Figure 2 and Figure 4 , the thickness T1 of the first wear-resistant piece 41 is the distance between the surface of the first wear-resistant piece 41 in contact with the second scroll 20 and the first sealing surface 310 of the first sealing piece 31. Wherein, the first sealing surface 310 can refer to the surface of the first sealing piece 31 in contact with the first wear-resistant piece 41.

[0058] As shown in Figure 3 and Figure 5 , the thickness T2 of the second wear-resistant piece 42 is the distance between the surface of the second wear-resistant piece 42 in contact with the first scroll 10 and the second sealing surface 320 of the second sealing piece 32. Wherein, the second sealing surface 320 can refer to the surface of the second sealing piece 32 in contact with the second wear-resistant piece 42.

[0059] In some embodiments, one side of the first wear-resistant piece 41 facing the first sealing piece 31 is provided with a first wear-resistant coating. One side of the second wear-resistant piece 42 facing the second sealing piece 32 is provided with a second wear-resistant coating. Wherein, the first wear-resistant coating or the second wear-resistant coating can be one of a nickel plating layer, a nickel-phosphorus plating Teflon layer, a molybdenum disulfide plating layer, a polyether ether ketone plating layer, and a graphite layer. Specifically, the first wear-resistant coating can be deposited on one side of the first wear-resistant piece 41 facing the first sealing piece 31 by physical vapor deposition, such as magnetron sputtering. Similarly, the deposition method of the second wear-resistant coating can also refer to the deposition method of the first wear-resistant coating. In this way, by depositing the first wear-resistant coating on the surface of the first wear-resistant piece 41 and depositing the second wear-resistant coating on the surface of the second wear-resistant piece 42, the wear resistance of the first wear-resistant piece 41 and the second wear-resistant piece 42 can be further improved.

[0060] Referring to Figures 6 to 8 , Figure 6 is Figure 1 a plan view of the compressor in the first state in the embodiment shown. Figure 7 is Figure 1 a plan view of the compressor in the second state in the embodiment shown. Figure 8 is Figure 1 a cross-sectional structural view of the first sealing piece and the second wear-resistant piece installed on the first scroll in the embodiment shown.

[0061] In some embodiments, such as Figures 6 to 8 As shown, when the compressor 100 is working, outside gas can be drawn into the compressor 100 through the suction port 60, for example, into the first scroll plate 10. When the second scroll plate 20 completes one rotational motion or circular translation relative to the first scroll plate 10, the compressed outside gas can be discharged from the compressor 100 through the exhaust port 50.

[0062] like Figure 6 and Figure 7 As shown, the first state can refer to the compressor 100 being in the intake state, and the second state can refer to the compressor 100 being in the compression state. The following is a brief description of the operation of the compressor 100 in the intake and compression states. Specifically, when the compressor 100 is in the intake state, the eccentric shaft drives the second scroll 20 to move relative to the first scroll 10. For example, the second scroll 20 can be driven to rotate or translate around the first scroll 10. At this time, the outer space of the first scroll 10 is connected to the intake port 60. As the second scroll 20 moves, the second scroll 20 and the first scroll 10 mesh with each other to form several crescent-shaped compression chambers. External gas enters the outer space of the first scroll 10 through the intake port 60 and is drawn into the several crescent-shaped compression chambers. Before the second scroll 20 completes one rotational or circular translation relative to the first scroll 10, the outer space of the first scroll 10 remains connected to the intake port 60, maintaining the continuous intake process. In this way, outside gas can be continuously drawn into the compressor 100, preparing for the subsequent compression process.

[0063] As outside gas is drawn into several crescent-shaped compression chambers, these chambers gradually move towards the center of the first volute 10 as the second volute 20 continues to move. During this process, the volume of each compression chamber gradually decreases. Due to the reduced volume, the gas within the chambers is gradually compressed, and the pressure gradually increases. The pressure difference between adjacent compression chambers is small, reducing gas leakage. When the compression chambers reach the center of the first volute 10, the gas has been compressed to the required high pressure. At this point, the compression chambers connect to the exhaust port 50, and the compressed gas is discharged through the exhaust port 50. Thus, the intake, compression, and exhaust processes are completed, achieving the purpose of compressing the gas.

[0064] from Figure 6 and Figure 7It can be seen that, in the process of the compressor 100 being converted from the suction state to the compression state, the projection of the movement track of the first sealing member 31 on the first plane X-Y falls within the projection of the first wear-resistant member 41 on the first plane X-Y, that is, the movement track of the first sealing member 31 can be covered by the first wear-resistant member 41 at all times, so that in the process of the second scroll plate 20 rotating relative to the first scroll plate 10, direct contact between the first sealing member 31 and the tooth bottom of the second scroll tooth 21 can be avoided, and the wear rate of the first sealing member 31 can be effectively reduced. Similarly, the movement track of the second sealing member 32 can also be covered by the second wear-resistant member 42 at all times, and details can be referred to the related content of the first sealing member 31, which will not be repeated here.

[0065] In some embodiments, the compressor 100 further comprises a first elastic member 71. The first elastic member 71 is accommodated in the first sealing groove 101, and the first elastic member 71 abuts against the side of the first sealing member 31 away from the first wear-resistant member 41.

[0066] In some embodiments, the compressor 100 further comprises a second elastic member 72. The second elastic member 72 is accommodated in the second sealing groove 201, and the second elastic member 72 abuts against the side of the second sealing member 32 away from the second wear-resistant member 42. Specifically, the first elastic member 71 or the second elastic member 72 can be a strip structure, such as a rubber strip.

[0067] In some embodiments, the present application also provides an oxygen generating device.
