Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of scroll compressor manufacturing, in particular to a compressor and an oxygen generating device. BACKGROUND
[0002] The scroll compressor realizes gas compression by the relative revolution of the moving scroll and the fixed scroll to continuously change the enclosed volume. However, due to the machining error of the moving scroll and the fixed scroll, the axial wear of the moving scroll and the fixed scroll is prone to occur during the relative movement, which further leads to the leakage of the scroll and reduces the performance of the compressor. In order to compensate for the machining error of the axial size of the moving scroll and the fixed scroll and avoid the axial leakage caused thereby, a tooth tip sealing strip structure is added on the tooth tip of the moving scroll and the fixed scroll in the related technology. Although this structure can reduce the axial wear of the moving scroll and the fixed scroll to a certain extent, the sealing strip will also be gradually worn out with the increase of the working time of the compressor, so that the leakage problem cannot be completely solved.

DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.
[0026] In the following description, specific details are set forth in order to provide a thorough understanding of the present application, but the present application can be practiced without one or more of the specific details. Moreover, well-known methods, structures, interfaces, and techniques have not been described in detail so as not to unnecessarily obscure the application.
[0027] The terms "first", "second", and the like in the specification and claims of this application are used for descriptive purposes only and do not connote or imply any relative importance of the indicated elements. Thus, a feature described as "first" or "second" can implicitly or explicitly include at least one of the indicated features. The meaning of "a", "an", and "the" includes singular and plural referents unless the context clearly dictates otherwise. The terms "comprising", "having", "including", and the like in the specification and claims of this application are used in their open-ended, non-limiting sense to encompass both express and implied descriptions of the enumerated steps or components. For example, a process, method, system, product, or apparatus that comprises a list of steps or components is not limited to only those steps or components but can also encompass other steps or components not expressly listed or inherent to such process, method, system, product, or apparatus.
[0028] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase that "an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive or alternative embodiments. It is expressly understood that the embodiments described herein are combinable.
[0029] The application will be described in detail below with reference to the attached drawings and embodiments.
[0030] The working principle of scroll compressor is based on the precise matching movement of the orbiting scroll and the fixed scroll. In the working process, the orbiting scroll revolves eccentrically around the fixed scroll, and the two are meshed to form a series of continuous compression chambers. With the rotating movement of the orbiting scroll, the volume of these compression chambers gradually decreases from outside to inside, thereby sequentially completing the processes of gas suction, compression, and discharge. In terms of structural features, the orbiting scroll and the fixed scroll have similar geometric specifications, but the volute profiles of the two are 180° out of phase, i.e., the unwinding directions are opposite. In the assembly process of the compressor, the orbiting scroll and the fixed scroll need to be strictly axially aligned and radially matched to ensure the formation of a complete compression system.
[0031] However, due to the machining precision and assembly process, the scroll heights of the orbiting scroll and the fixed scroll are difficult to be consistent with the theoretical value, and then, with the long-term use of the scroll compressor, the relative movement of the orbiting scroll and the fixed scroll will cause axial wear, and axial gaps will inevitably be formed at the tooth top of the scroll. The existence of the axial gaps will form a gas leakage channel, causing part of the high-pressure gas to leak from the compression chamber to the low-pressure area, thereby reducing the volumetric efficiency of the scroll compressor and affecting the coefficient of performance (COP) and the isentropic efficiency of the scroll compressor. Therefore, how to compensate for the axial gaps at the tooth top of the orbiting scroll and the fixed scroll has become one of the key technical problems to be optimized in the design of the scroll compressor. In the related art, a sealing strip structure is usually added at the tooth top of the orbiting scroll and the fixed scroll to alleviate the axial gaps, but with the use of the scroll compressor, the sealing strip itself will inevitably be worn, so that the above-mentioned gas leakage problem cannot be completely solved.
[0032] Figure 1 is a cross-sectional view of a compressor 1 in the embodiments of the present application. In some embodiments, the compressor 1 generally comprises a first scroll 11 and a second scroll 12. The first scroll 11 comprises a first scroll body 111 and a first scroll tooth 112 disposed on the first scroll body 111, and the second scroll 12 comprises a second scroll body 121 and a second scroll tooth 122 disposed on the second scroll body 121, the first scroll tooth 112 and the second scroll tooth 122 being engaged with each other. The first scroll tooth 112 is provided with a first sealing groove 1121 at an end away from the first scroll body 111.
[0033] In some specific embodiments of the present application, the first scroll 11 is one of a fixed scroll and an orbiting scroll, and the second scroll 12 is the other of the fixed scroll and the orbiting scroll. As shown in Figure 1 , the first scroll 11 is an orbiting scroll, and the second scroll 12 is a fixed scroll. Of course, in other embodiments, the first scroll 11 can be a fixed scroll, and the second scroll 12 can be an orbiting scroll. Figure 1 Part A of the figure shows the structure of the engagement between the second scroll body 121 and the first scroll tooth 112, Figure 1 Part B of the figure shows the structure of the engagement between the first scroll body 111 and the second scroll tooth 122.
[0034] Figure 2 is Figure 1 an enlarged view of an embodiment of Part A. As shown in Figure 2 , the compressor 1 further comprises a first elastic member 113 and a first sealing member 114. The first elastic member 113 is disposed in the first sealing groove 1121. The first sealing member 114 is at least partially disposed in the first sealing groove 1121 and abuts against the first elastic member 113 and the second scroll body 121, respectively.
[0035] In some embodiments, the first elastic member 113 further comprises a first elastic part 1131 and a first elastic support leg 1132 connected thereto. The first elastic part 1131 abuts against the first sealing member 114. The first elastic support leg 1132 is arranged on a side of the first elastic part 1131 away from the first sealing member 114 and abuts against the bottom wall of the first sealing groove 1121. As shown in Figure 2 The first scroll 11 has an axial direction Y substantially parallel to the extending direction of the first scroll teeth 112 and the second scroll teeth 122.
[0036] It can be understood that during the long-term operation of the compressor 1, the first scroll 11 and the second scroll 12 continuously move relative to each other, which will cause the wear of the contact surface between the first sealing member 114 and the second scroll body 121 to gradually increase, thereby weakening the axial sealing performance of the first sealing member 114. By arranging the first elastic member 113 at the end of the first sealing member 114 away from the second scroll body 121, and the first elastic member 113 having the first elastic support leg 1132 abutting against the bottom wall of the first sealing groove 1121, when the wear of the first sealing member 114 has not yet reached a degree sufficient to form an axial gap between the second scroll body 121, the relative movement of the first scroll 11 and the second scroll 12 will cause the first sealing member 114 to press the first elastic member 113, so that the first elastic member 113 stores elastic potential energy. This elastic potential energy is converted into an axial thrust when the first sealing member 114 is worn to a degree sufficient to form an axial gap with the second scroll body 121, pushing the first sealing member 114 towards the surface of the second scroll body 121, thereby realizing that the first elastic member 113 can dynamically compensate for the axial gap between the first sealing member 114 and the second scroll body 121 by adapting to the wear of the first sealing member 114, thereby improving the axial sealing reliability of the compressor 1 and reducing the possibility of axial leakage of the compressor 1. The arrangement of the first elastic support leg 1132 can optimize the thrust transmission of the first elastic member 113, so that the first sealing member 114 is uniformly stressed, local wear is reduced, and the sealing life is prolonged.
[0037] In some embodiments, the first elastic part 1131 is provided with a sealing surface facing the first seal 114, and the sealing surface of the first elastic part 1131 abuts against the first seal 114. In some embodiments, the sealing surface continuously extends along the radial direction X of the first scroll 11. Here, the radial direction X of the first scroll 11 is a direction perpendicular to the axial direction Y of the first scroll 11. In this way, the first elastic part 1131 and the first seal 114 are in contact with each other in a large area, so that the thrust force exerted by the first elastic part 1131 on the first seal 114 is directly transmitted to the first seal 114, improving the transmission efficiency of the thrust force and facilitating the first seal 114 to compensate for the axial gap of the compressor 1. At the same time, the large-area contact can also reduce the requirement for the thrust force exerted on the first elastic part 1131, thereby reducing the load of the first elastic part 1131 and improving the durability of the first elastic part 1131. In addition, the large-area contact can also make the thrust force distribution of the first elastic part 1131 on the first seal 114 more uniform, reduce local stress concentration, and prolong the service life of the first seal 114.
[0038] In some embodiments, the number of first elastic support feet 1132 is at least two, and the at least two first elastic support feet 1132 are arranged at intervals. The sum of the cross-sectional areas of the at least two first elastic support feet 1132 is less than the cross-sectional area of the sealing surface of the first elastic part 1131 along the radial direction X of the first scroll 11. In other words, the first elastic support feet 1132 are provided with gaps between each other, so that the first elastic part 1131 forms an opening or a notch on one side of the first elastic support feet 1132. In this way, the consumption of the first elastic part 1131 can be reduced while ensuring the compensation of the axial gap of the compressor 1, and the response speed of the first elastic part 1131 to generate elastic force to push the first seal 114 can be improved.
[0039] In some embodiments, the first elastic part 1131 has a center line parallel to the axial direction Y of the first scroll 11. The first elastic part 1131 is symmetrically arranged relative to the center line. It can be understood that the first elastic part 1131 with an axisymmetric shape can uniformly distribute elastic force in the circumferential direction, so as to balance the axial thrust force received by the first seal 114 and avoid local wear or sealing failure caused by uneven force. In addition, the axisymmetric design not only enables the elastic part to maintain stable deformation characteristics when the first scroll 11 and the second scroll 12 move relative to each other, so as to more reliably adapt to the wear change of the seal to improve the stability and reliability of the axial gap compensation, but also uniformly transmits elastic force to reduce local stress concentration, thereby reducing the fatigue loss of the elastic part itself and prolonging the service life of the elastic part.
[0040] In some embodiments, the first elastic part 1131 has a special shape. For example, as shown in FIG. 1, the first elastic part 1131 has a plurality of protrusions 1133 arranged at intervals along the circumferential direction of the first elastic part 1131. In this way, the first elastic part 1131 can be more firmly fixed on the first scroll 11, and the first elastic part 1131 can be more firmly fixed on the first seal 114. Figure 2In the illustrated embodiment, the first elastic element 113 is shaped similarly to an inverted "U". For example, in... Figure 3 In the illustrated embodiment, the first elastic element 113 is shaped similarly to an "M". For example, in... Figure 4 In the embodiment shown, the first elastic element 113 is shaped like an "X".
[0041] The above describes embodiments of three different cross-sectional shapes of the first elastic element 113 along the axial direction Y of the first scroll 11. Of course, in other embodiments, the axial cross-sectional shape of the first elastic element 113 can also be other, as long as it can stably and reliably compensate for the axial clearance of the compressor 1.
[0042] In some embodiments, the first elastic element 113 is a rubber elastic element. This application does not limit the material and elastic coefficient of the first elastic element 113, as long as the first elastic element 113 can provide sufficient thrust to the first seal 114 to eliminate the axial gap between the first seal 114 and the second scroll body 121.
[0043] Figure 5 yes Figure 1 A partially enlarged schematic diagram of another embodiment of part A. In some embodiments, such as Figure 5 As shown, the first elastic element 113 and the first sealing element 114 can be an integral structure. In some embodiments, the first elastic element 113 and the first sealing element 114 can also be independent structures that can be assembled by means of adhesive bonding, etc., and this application does not limit this. When the first elastic element 113 and the first sealing element 114 are an integral structure, the first elastic element 113 and the first sealing element 114 can have the same material or different materials, and this application does not limit this, as long as the first elastic element 113 can provide sufficient axial thrust to the first sealing element 114.
[0044] In some embodiments, such as Figures 2-5 As shown, the first sealing groove 1121 includes two side walls, which are respectively connected to the bottom wall and are respectively disposed on opposite sides of the bottom wall.
[0045] In some embodiments, a gap is provided between the first elastic member 113 and the two side walls of the first sealing groove 1121. Optionally, the side walls of the first sealing groove 1121 are recessed in the radial direction X of the first scroll plate 11 away from the first elastic member 113 at a position corresponding to the first elastic member 113, so as to keep the first elastic member 113 spaced apart from the side walls of the first sealing groove 1121. By reserving a gap between the first elastic member 113 and the first sealing groove 1121, sufficient deformation space can be provided for the first elastic member 113. Specifically, when the compressor 1 is in operation, the first elastic member 113 can be pressed by the first sealing member 114 in the axial direction Y or rebound to apply a pushing force to the first sealing member 114, and the reserved gap can allow the first elastic member 113 to elastically deform freely under force without being limited by or generating additional frictional loss with the side walls of the first sealing groove 1121, thereby maintaining the elastic force of the first elastic member 113 and prolonging its service life.
[0046] In some embodiments, a gap is provided between the first sealing member 114 and the two side walls of the first sealing groove 1121. Optionally, the side walls of the first sealing groove 1121 can be recessed in the radial direction X of the first scroll plate 11 away from the first sealing member 114 at a position corresponding to the first sealing member 114, so as to keep the first sealing member 114 spaced apart from the side walls of the first sealing groove 1121. By reserving a gap between the first sealing member 114 and the first sealing groove 1121, sufficient displacement space can be provided for the first sealing member 114. Specifically, when the compressor 1 is in operation, especially when the first elastic member 113 applies an axial pushing force to the first sealing member 114, the first sealing member 114 will displace or deflect axially, and the reserved gap can not only prevent the first sealing member 114 from being stuck in the side walls of the first sealing groove 1121 due to insufficient space during movement, but also minimize the frictional loss between the first sealing member 114 and the side walls of the first sealing groove 1121, thereby prolonging the service life of the first sealing member 114.
[0047] In some embodiments, the first sealing groove 1121 extends from one side of the first scroll tooth 112 facing away from the first scroll plate body 111 to the other side of the first scroll tooth 112, and the first sealing member 114 protrudes from the first sealing groove 1121 from the side facing away from the first elastic member 113. In combination with the above-mentioned gap between the first sealing member 114 and the side walls of the first sealing groove 1121, the first sealing member 114 can be prevented from being stuck in the side walls of the first sealing groove 1121 due to insufficient space during movement, and the frictional loss between the first sealing member 114 and the side walls of the first sealing groove 1121 can be minimized, thereby prolonging the service life of the first sealing member 114. Figures 1-5As shown, the first sealing groove 1121 is arranged at the top of the first scroll tooth 112 and its opening faces the second scroll body 121. The first sealing groove 1121 is used to provide a containing space for the first sealing member 114 and the first elastic member 113, and the first sealing member 114 at least partially protrudes from the first sealing groove 1121, so that the sealing surface of the first sealing member 114 and the surface of the second scroll body 121 can apply a thrust force to each other. Specifically, when there is no axial gap between the second scroll body 121 and the first sealing member 114, the surface of the second scroll body 121 thrusts the sealing surface of the first elastic member 113 to compress the first elastic member 113, so that the first elastic member 113 stores elastic potential energy which can provide an axial thrust force for the first sealing member 114. Further, when a gap is generated between the first sealing member 114 and the second scroll body 121, the elastic potential energy stored by the first elastic member 113 can drive the first sealing member 114 to move towards the second scroll body 121 to compensate for the gap.
[0048] In some embodiments, the first scroll 11 is provided with a scroll line, and the first scroll tooth 112, the first sealing groove 1121, the first elastic member 113 and the first sealing member 114 respectively extend along the scroll line. The extension length of the first sealing groove 1121 is less than the extension length of the first scroll tooth 112.
[0049] In some embodiments, the first elastic member 113 can include at least one elastic segment, and the at least one elastic segment is sequentially arranged along the extension direction of the first elastic member 113. Figure 6 and 7 As shown, Figure 6 is a radial cross-sectional schematic view of the first elastic member 113 having one elastic segment in the embodiment of the utility model, Figure 7 is a radial cross-sectional schematic view of the elastic member having multiple elastic segments in the embodiment of the utility model. In some embodiments of the present application, the first elastic member 113 includes at least one sequentially connected elastic segment, and the at least one elastic segment is connected to the first sealing member 114 respectively. In this way, the complexity and cost of the mold in the production process can be reduced.
[0050] In the above embodiments, the first sealing groove 1121 is arranged on the first scroll tooth 112, and the sealing structure composed of the sealing member and the elastic member can be arranged only on the first scroll 11. Of course, in other embodiments, the first sealing groove 1121 can be arranged on the first scroll tooth 112 and the sealing structure can be arranged on the first scroll 11 at the same time, and the second sealing groove 1221 can be arranged on the second scroll tooth 122 away from the second scroll body 121 and the sealing structure can be arranged on the second scroll 12. Figure 8 is Figure 1 is a partial enlarged schematic view of an embodiment of part B in FIG. 8. As Figure 8As shown, the compressor 1 further comprises a second elastic member 123 and a second sealing member 124. The second elastic member 123 is arranged in the second sealing groove 1221. The second sealing member 124 is at least partially arranged in the second sealing groove 1221 and abuts against the second elastic member 123 and the first scroll body 111 respectively.
[0051] In some embodiments, the second elastic member 123 further comprises a second elastic portion 1231 and a second elastic support leg 1232 connected with each other. The second elastic portion 1231 abuts against the second sealing member 124. The second elastic support leg 1232 is arranged on the side of the second elastic portion 1231 away from the second sealing member 124 and abuts against the bottom wall of the second sealing groove 1221. By arranging the second sealing member 124 and the second elastic member 123, the axial gap between the second sealing member 124 and the first scroll body 111 can be compensated, the continuous effectiveness of the sealing performance can be improved, and the possibility of axial leakage of the compressor 1 can be further reduced.
[0052] The second elastic member 123, the second sealing member 124, and the second sealing groove 1221 are arranged in the second sealing groove 1221. Figures 1-7 The structures, connection relationships, and arrangement of the first elastic member 113, the first sealing member 114, and the first sealing groove 1121 are similar to those of the second elastic member 123, the second sealing member 124, and the second sealing groove 1221. For details, refer to the descriptions of the corresponding elements in the above embodiments.
[0053] In some embodiments, when the sealing structure is only provided on the first scroll 11, i.e. only the first sealing groove 1121 is opened, when the first scroll 11 and the second scroll 12 increase the axial gap due to wear after long-term use, the first elastic member 113 can provide sufficient axial compensation force for the first sealing member 114 through its elastic deformation. That is, the sum of the maximum elongation length of the first elastic member 113 and the length of the first sealing member 114 can at least cover the length difference between the distance from the bottom wall of the first sealing groove 1121 to the first scroll body 111 and the second scroll tooth 122, thereby forming an effective axial seal between the second scroll body 121 and the first sealing member 114. Similarly, when the sealing structure is provided on both the first scroll 11 and the second scroll 12, i.e. both the first sealing groove 1121 and the second sealing groove 1221 are opened, the maximum elastic deformation of the first elastic member 113 can at least cover the axial gap between the first sealing member 114 and the second scroll body 121, and the maximum elastic deformation of the second elastic member 123 can at least cover the axial gap between the second sealing member 124 and the first scroll body 111, thereby ensuring that when the first sealing member 114 and the second sealing member 124 increase the axial gap due to wear, the first elastic member 113 and the second elastic member 123 can provide sufficient axial compensation force for the first sealing member 114 and the second sealing member 124, respectively, through their elastic deformation, thereby forming effective axial seals at the first scroll 11 and the second scroll 12, respectively, and further increasing the reliability of the axial seal.
[0054] In some embodiments, the present application also provides an oxygen production device comprising the compressor 1 as described above.
[0055] In summary, the embodiment of the present application provides a compressor 1, which comprises a first scroll 11, a second scroll 12, a first elastic member 113 and a first sealing member 114. The first scroll 11 comprises a first scroll body 111 and a first scroll tooth 112 arranged on the first scroll body 111. The first scroll tooth 112 is provided with a first sealing groove 1121 at an end away from the first scroll body 111. The second scroll 12 comprises a second scroll body 121 and a second scroll tooth 122 arranged on the second scroll body 121. The first scroll tooth 112 and the second scroll tooth 122 are engaged with each other. The first elastic member 113 is arranged in the first sealing groove 1121. The first sealing member 114 is at least partially arranged in the first sealing groove 1121. The first sealing member 114 abuts against the first elastic member 113 and the second scroll body 121, respectively. The first elastic member 113 comprises a first elastic part 1131 and a first elastic support leg 1132 connected with each other. The first elastic part 1131 abuts against the first sealing member 114. The first elastic support leg 1132 is arranged at a side of the first elastic part 1131 away from the first sealing member 114 and abuts against a bottom wall of the first sealing groove 1121. The present application sets the first elastic member 113 with elastic force at the bottom of the first sealing member 114, and the first elastic member 113 has the first elastic support leg 1132 abutting against the bottom wall of the first sealing groove 1121. When there is an axial gap between the first sealing member 114 and the second scroll body 121, the first elastic member 113 applies stable and uniform axial thrust to the first sealing member 114 to facilitate close contact between the first sealing member 114 and the second scroll body 121, so that the first elastic member 113 can continuously compensate for the axial gap by adapting to the wear of the first sealing member 114, thereby improving the axial sealing reliability of the compressor 1 and maintaining long-term sealing effect.
