[0034] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0035] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0036] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0037] In an air-conditioning system, a rolling rotor compressor is mainly composed of a pump body, a casing, a liquid reservoir, a motor, etc. The liquid reservoir has functions such as liquid storage, oil-gas separation, and oil return. These functions can be completely replaced by the oil separator and gas separator in the air-conditioning system, so that the liquid reservoir on the compressor can be replaced by the intake pipe. However, the extension length of the intake pipe on the existing compressor is generally large, making it difficult to ensure the stability of the intake end of the intake pipe.

[0038] Analysis of the above reasons shows that the intake pipe of the existing compressor is usually connected to the compressor body only at the intake hole, resulting in a lack of connection foundation for the entire extended pipe section of the intake pipe. A connection structure can be set in the middle of the intake pipe to improve the above problem.

[0039] In view of this, the present application provides a compressor, which aims to improve the problem of poor stability of the intake end of the intake pipe on the compressor. Figure 1 A schematic structural diagram of an embodiment of a compressor provided in this application;

[0040] Figure 2 A schematic structural diagram of another embodiment of a compressor provided in this application; Figure 3 for Figure 2 Schematic diagram of the cross-sectional structure of the compressor; Figure 4 for Figure 3 Schematic diagram of the connection structure between the middle intake pipe and the collar.

[0041] See also Figure 1 and Figure 2 In one embodiment of the present application, the compressor 100 includes a shell 1, an air intake pipe 2 and a connecting portion 3. The shell 1 has an air intake hole 11 and a positioning portion 12 along a first direction; the air intake pipe 2 extends along the first direction of the shell 1, and one end of the air intake pipe 2 is connected to the air intake hole 11; the connecting portion 3 is arranged around the air intake pipe 2, and the connecting portion 3 is connected to the positioning portion 12.

[0042] It should be noted that the compressor 100 includes a compressor body, and the shell 1 is the shell 1 of the compressor body, on which an air inlet 11 is formed. The compressor 100 body usually also includes a cylinder body arranged in the shell 1, and the cylinder body is connected to the air inlet 11. The embodiment of the present application does not limit the working parts on the compressor 100 other than the shell 1, the air inlet pipe 2 and the connecting part 3.

[0043] The shell 1 of the compressor 100 usually has a height dimension. "The air intake hole 11 and the positioning portion 12 are arranged along the first direction" can be understood as the air intake hole 11 and the positioning portion 12 are arranged along the height direction of the shell 1. The cylinder body of the compressor 100 is generally located at the bottom, so the setting position of the air intake hole 11 is usually also close to the bottom of the shell 1; "one end of the air intake pipe 2 is connected to the air intake hole 11" can be understood as the bottom end of the air intake pipe 2 is connected to the air intake hole 11, and connection also means being fixed.

[0044] The positioning portion 12 is arranged on the shell 1 and is used for connection with the connecting portion 3. The relationship between the positioning portion 12 and the shell 1 can be that the positioning portion 12 is detachably arranged on the main part of the shell 1, or the positioning portion 12 and the main part of the shell 1 are integrally formed. There are many situations in the specific structural form of the positioning portion 12. In the embodiment of the present application, the positioning portion 12 is mainly for connection with the connecting portion 3 and plays the role of calibrating the position. This embodiment does not limit the connection form of the positioning portion 12 and the shell 1, nor the specific structural form of the positioning portion 12.

[0045] The connecting portion 3 can be arranged in a surrounding manner on the intake pipe 2. There are many structural forms of this connecting portion 3. For example, the connecting portion 3 includes a steel wire rope arranged around the intake pipe 2. This embodiment does not limit the specific structural form of the connecting portion 3; there are many connection forms between the connecting portion 3 and the positioning portion 12. For example, the connecting portion 3 and the positioning portion 12 are detachably connected, and for another example, the connecting portion 3 and the positioning portion 12 are integrally connected. This embodiment does not limit this.

[0046] The technical solution provided by the present application is that one end of the air intake pipe 2 is connected to the air intake hole 11 of the shell 1. Therefore, the end can be fixed, and the main pipe section of the air intake pipe 2 can be stably installed to the shell 1 through the connecting portion 3, thereby increasing the connection points between the air intake pipe 2 and the shell 1, and the air intake pipe 2 is more stably fixed, thereby improving the problem of poor stability of the air intake end of the air intake pipe 2; moreover, since the connecting portion 3 is arranged around the air intake pipe 2, the connection method of the connecting portion 3 and the air intake pipe 2 is a simple detachable connection, and there is no need to destroy the structure of the air intake pipe 2 itself due to the connection between the connecting portion 3 and the air intake pipe 2 (for example, the connecting portion 3 and the air intake pipe 2 are connected). If connected with screws, it is necessary to drill holes or weld nuts on the intake pipe 2, which will destroy the integrity of the intake pipe 2 itself, or require the intake pipe 2 to have a thicker pipe wall); at the same time, since the positioning portion 12 is directly related to the position of the connecting portion 3 on the intake pipe 2, the positioning portion 12 itself has the effect of locating the elevation of the connecting portion 3. During the production process of the shell 1, the positioning portion 12 can be directly molded onto the shell 1. During the subsequent installation of the intake pipe 2, there is no need to repeatedly measure and find the position of the connecting portion 3 (the position of the positioning portion 12 is also the accurate position). Directly connecting the positioning portion 12 and the connecting portion 3 can ensure that the connecting portion 3 is properly positioned on the intake pipe 2.

[0047] Compared with the traditional solution of air intake through the liquid reservoir, the solution of the present application reduces the radial size of the compressor 100 itself, saves the space required for the installation of the compressor 100, improves the rotational vibration of the compressor 100, and optimizes the noise OA value.

[0048] In some embodiments, the connecting portion 3 is detachably connected to the positioning portion 12 .

[0049] It should be noted that there are many ways of detachable connection, and the specific detachable method depends on the specific structure of the connecting part 3.

[0050] According to the above technical solution, the connecting portion 3 and the positioning portion 12 are connected by a detachable connection method, which is conducive to the removal and replacement of the intake pipe 2 from the shell 1 of the compressor 100, and gives the compressor 100 more possibilities to change the intake method in the future. For example, after the cylinder specifications of the compressor 100 are upgraded, the specifications of the intake pipe 2 can be adaptively upgraded.

[0051] For further information, see Figure 1 In some embodiments, the connection portion 3 includes a band 31, which is provided on the positioning portion 12 and passes through the intake pipe 2. It should be noted that the band 31 is connected to the intake pipe 2 and the positioning portion 12 in such a way that the middle portion of the band 31 passes through the intake pipe 2, and both ends of the band 31 are detachably connected to the positioning portion 12. There are various ways to connect the band 31 and the positioning portion 12, for example, Figure 1 In the embodiment, a through-hole 121 is provided on the positioning portion 12, and the two ends of the cuff 31 extend into the through-hole 121 from the two ends of the through-hole 121. Of course, this method requires the cuff 31 to have a certain rigidity to ensure that the two ends of the cuff 31 can be maintained in the through-hole 121. For another example, a through-hole 121 is provided on the positioning portion 12, and the two ends of the cuff 31 pass through the through-hole 121 from the two ends of the through-hole 121, and are knotted or threaded on the side of the intake pipe 2 away from the positioning portion 12.

[0052] According to the above technical solution, the strap 31 is detachably connected to the positioning portion 12 , and no additional equipment is required, which facilitates operation by operators.

[0053] See also Figure 2 In other embodiments, the connecting portion 3 includes a collar 32 that is sleeved over the intake pipe 2 and connected to the positioning portion 12. It should be noted that the collar 32 is sleeved over the intake pipe 2, which can be understood as a clearance fit between the collar 32 and the intake pipe 2, allowing the collar 32 to be inserted from one end of the intake pipe 2 and slid on the intake pipe 2 to adjust the installation position. The collar 32 and the positioning portion 12 can also be connected in two ways: a detachable connection and a fixed connection, which are not limited in this embodiment.

[0054] According to the above technical solution, the sleeve 32 is sleeved on the intake pipe 2, and the effective area between the sleeve and the intake pipe 2 is large, so as not to damage the surface of the intake pipe 2 during the connection process. At the same time, the sleeve has good rigidity and can limit the movement of the intake pipe 2 in all radial directions, thereby ensuring the stability of the connection of the intake pipe 2.

[0055] It should be noted that the arrangement of the collar 32 in the above embodiment and the arrangement of the strap 31 in the above embodiment are two parallel technical solutions. It can be understood that the collar 32 and the strap 31 can be arranged on the positioning portion 12 at the same time, or one of them can be arranged on the positioning portion 12 selectively.

[0056] Furthermore, the collar 32 is connected to the positioning portion 12 by welding.

[0057] It should be noted that the ring 32 is welded to the positioning portion 12, and there are many possible welding methods. For example, the ring 32 is abutted against the plane of the positioning portion 12 through its circumferential side wall. At this time, there is a connecting line extending along the first direction between the ring 32 and the positioning portion 12. Welding them on both sides of the connecting line can ensure the connection basis between the ring 32 and the positioning portion 12; further, for example, a concave arc surface is provided on the positioning portion 12 relative to the ring 32, and the circumferential side wall of the ring 32 is adapted to abut against the arc surface of the positioning portion 12. At this time, the ring 32 and the positioning portion 12 are in surface contact, and welding is performed on the periphery of the contact surface to ensure the connection basis between the ring 32 and the positioning portion 12.

[0058] According to the above technical solution, the collar 32 and the positioning portion 12 are connected by welding, that is, the collar 32 and the positioning portion 12 are integrally arranged, so that the collar 32 and the positioning portion 12 are not easy to separate, and can maintain a stable connection between the intake pipe 2 and the shell 1 under long-term vibration conditions of the compressor 100.

[0059] See also Figure 3 and Figure 4 In other embodiments, in the first direction, the height of the positioning portion 12 is H0, and the height of the ring 32 is H1, wherein H0≤H1≤1.5H0.

[0060] It should be noted that the height of the positioning portion 12 and the height of the collar 32 refer to their own dimensions, rather than the specific heights of the positioning portion 12 and the collar 32 on the housing 1 .

[0061] In this embodiment, the height dimension of the positioning portion 12 is associated with the height dimension of the ring 32, wherein H0≤H1≤1.5H0 means that the height dimension H0 of the ring 32 can be the same as the height dimension H1 of the positioning portion 12, or it can be 1.1 times, 1.2 times, 1.3 times, 1.4 times or even 1.5 times the height dimension H1 of the positioning portion 12. Of course, it can also be any value in the above range. This application does not limit the specific multiple relationship between the height dimension of the ring 32 and the height dimension of the positioning portion 12.

[0062] According to the above technical solution, it is more reasonable to set the height dimension H1 of the ring 32 between 1.0 times and 1.5 times the height dimension H0 of the positioning portion 12. While ensuring that the ring 32 has sufficient contact area with the intake pipe 2, it can also limit the material usage of the ring 32 to a reasonable range, thereby controlling the production cost of the ring 32.

[0063] The above embodiments do not limit the specific structure of the intake pipe 2. In some embodiments, in the first direction, the intake pipe 2 has multiple pipe sections 2a connected in sequence, the connecting portion 3 is arranged on a pipe section 2a at the middle position, and a pipe section 2a at the end position is connected to the intake hole 11.

[0064] It should be noted that multiple pipeline sections 2a are connected in sequence, which means that multiple pipeline sections 2a are arranged along the first direction, and two adjacent pipeline sections 2a are connected end to end. The connection method can be, for example, a threaded connection or a sealed connection through a sealant, which is not limited in this embodiment.

[0065] Compared with directly integrally molding the intake pipe 2, the intake pipe 2 is configured to be formed by connecting multiple pipe sections 2a end to end, and multiple shorter pipe sections 2a can be processed separately, which can obviously reduce the processing difficulty and reduce the specifications of the processing equipment. Moreover, when the intake pipe 2 is integrally molded, if there is a defect in a part of the intake pipe 2, this may easily cause the entire intake pipe 2 to be scrapped. In this embodiment of the technical solution, if one of the pipe sections 2a has a defect, only the pipe section 2a needs to be replaced, which can reduce the amount of waste generated by the intake pipe 2.

[0066] Furthermore, in some embodiments, each pipeline section 2a is configured as a pipe section with a constant inner diameter, wherein:

[0067] Along the air inlet direction, in two adjacent pipeline sections 2a, the inner diameter of the pipeline section 2a close to the air inlet hole 11 is smaller than the inner diameter of the pipeline section 2a far from the air inlet hole 11; or, the inner diameters of multiple pipeline sections 2a are set to be equal.

[0068] It should be noted that equal inner diameter pipe sections mean that the inner diameters of the pipe section 2a at various positions along the extension path of the pipe section 2a are equal; the above two parallel technical features "along the air intake direction, among the two adjacent pipe sections 2a, the inner diameter of the pipe section 2a close to the air intake hole 11 is smaller than the inner diameter of the pipe section 2a away from the air intake hole 11" and "the inner diameters of the multiple pipe sections 2a are all set to be equal" can usually only be set at one of them.

[0069] According to the above technical solution, the same pipe diameter allows multiple pipe sections 2a to be processed by production equipment of the same specifications, which has lower requirements for the production line; and the pipe diameters of the multiple pipe sections 2a decrease successively, so that the pipe diameter of the intake end of the intake pipe 2 is larger than the aperture of the intake hole 11 on the shell 1, which can provide a larger intake volume for the cylinder body of the compressor 100 and increase the power of the compressor 100.

[0070] Specifically, see Figure 4 In some embodiments, in the first direction, the plurality of pipeline sections 2a include a first pipeline section 21, a second pipeline section 22, and a third pipeline section 23 sequentially arranged along the air intake direction, the inner diameter of the first pipeline section 21 is φa, the inner diameter of the second pipeline section 22 is φb, and the inner diameter of the third pipeline section 23 is φc, wherein φc≤φb≤φa.

[0071] In other embodiments, in the first direction, the multiple pipeline sections 2a include a first pipeline section 21, a second pipeline section 22 and a third pipeline section 23 arranged in sequence along the air intake direction; the connecting portion 3 is arranged in the second pipeline section 22; and the third pipeline section 23 is connected to the air intake hole 11.

[0072] Since the air intake pipe 2 extends along the first direction and one end is connected to the air intake hole 11, it can be determined that the extension path of the air intake pipe 2 is not complicated. It only needs to be set as a bend at one end to connect to the air intake hole 11. Therefore, there is no need to divide the air intake pipe 2 into too many pipe sections 2a (too many pipe sections 2a will increase the difficulty of connection, and two adjacent pipe sections 2a will usually hinder the airflow at their connection nodes. Too many connection nodes will easily lead to a decrease in the air intake amount of the air intake pipe 2). Therefore, in the technical solution of this embodiment, the air intake pipe 2 is set to consist of a first pipe section 21, a second pipe section 22 and a third pipe section 23. Taking into account factors such as production difficulty, connection difficulty, and control of air intake amount, it is more reasonable as a whole.

[0073] Further, see Figure 3 and Figure 4 In some embodiments, in the first direction, the length of the third pipeline section 23 is L0, and the length of the second pipeline section 22 is L1, wherein 0.5L1≤L0≤0.8L1.

[0074] It should be noted that, in this embodiment, the length dimension L0 of the third pipeline section 23 is associated with the length dimension L1 of the second pipeline section 22, wherein 0.5L1≤L0≤0.8L1 means that the length dimension L0 of the third pipeline section 23 can be 0.5 times, 0.6 times, 0.7 times or even 0.8 times the length dimension L1 of the second pipeline section 22. Of course, it can also be any value in the above range. This application does not limit the specific multiple relationship between the length dimension of the third pipeline section 23 and the length dimension of the second pipeline section 22.

[0075] According to the above technical solution, it is more reasonable to set the length dimension L0 of the third pipeline section 23 between 0.5 times and 0.8 times the length dimension L1 of the second pipeline section 22, ensuring that the length of the second pipeline section 22 is greater than the length of the third pipeline section 23, so that the connecting part 3 can fix the second pipeline section 22 with a larger length, which is beneficial to improving the overall stability of the intake pipe 2.

[0076] Please continue reading Figure 3 and Figure 4 In other embodiments, in the first direction, the length of the second pipeline section 22 is L1, and the distance between the middle of the positioning portion 12 and the end of the second pipeline section 22 close to the first pipeline section 21 is H2, wherein 0.4L1≤H2≤0.7L1.

[0077] It should be noted that, in this embodiment, the "length dimension L1 of the second pipeline section 22" and the "distance dimension H2 from the middle of the positioning portion 12 to the end of the second pipeline section 22 close to the first pipeline section 21" are associated, wherein 0.5L1≤L0≤0.8L1 means that H2 can be 0.4 times, 0.5 times, 0.6 times or even 0.7 times of L1, and of course it can also be any value in the above range. This application does not limit the specific multiple relationship between the "length dimension L1 of the second pipeline section 22" and the "distance dimension H2 from the middle of the positioning portion 12 to the end of the second pipeline section 22 close to the first pipeline section 21".

[0078] According to the above technical solution, it is more reasonable to set the "distance dimension H2 between the middle of the positioning part 12 and the end of the second pipeline section 22 close to the first pipeline section 21" between 0.4 times and 0.7 times the "length dimension L1 of the second pipeline section 22". This can ensure that the positioning part 12 is set in the middle position of the overall length of the intake pipe 2, which is beneficial to improving the overall stability of the intake pipe 2.
