Detailed Description

In order that the above objects, features and advantages of embodiments according to the present application may be more clearly understood, embodiments according to the present application will be described in further detail below with reference to the accompanying drawings and detailed description. It should be noted that features of embodiments according to the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth to provide a thorough understanding of embodiments according to the present application, however, embodiments according to the present application may be practiced in other ways than those described herein, and therefore the scope of protection afforded by embodiments according to the present application is not limited by the specific embodiments disclosed below.

Some embodiments provided in accordance with the present application are described below with reference to fig. 1-9.

Example 1

As shown in fig. 1 and 2, a getter structure 10 is provided according to an embodiment of the first aspect of the present application. The suction structure 10 includes a suction muffler 100, a bellows 102, and a suction connection pipe 104.

Specifically, the suction muffler 100 is provided with a suction joint 1006. One end of the bellows 102 is connected to the suction connection 1006, and the other end of the bellows 102 is a free end. One end of the suction connection pipe 104 is fixedly disposed, and the other end of the suction connection pipe 104 extends into the free end of the bellows 102. The suction communicating tube 104 is used for suction.

In this embodiment, by arranging the corrugated tube 102 and extending one end of the air suction communicating tube 104 into the free end of the corrugated tube 102, the concave and convex tube wall of the corrugated tube 102 can be utilized to form disturbance to the air flow, which is beneficial to reducing the excitation effect of the air flow on the cavity mode of the housing, thereby reducing the aerodynamic noise. Further, the combination of the bellows 102 and the suction connection pipe 104 is adopted, which is simple in structure, occupies a small space, and facilitates the miniaturization design of the compressor 20. Moreover, the air suction communicating pipe 104 only needs to extend into the corrugated pipe 102, and the air suction communicating pipe and the corrugated pipe do not need to be connected, so that the production and the installation are more convenient.

As shown in fig. 4 and 5, it should be noted that the other end of the suction communication pipe 104 protrudes into the bellows 102, that is, the suction communication pipe 104 and the bellows 102 are not connected or in contact with each other. Since the two are not in contact or connected, when the compressor 20 is in operation, the pulling force between the suction connection pipe 104 and the bellows 102 caused by vibration can be reduced, which is beneficial to improving the stability and reliability of the fixing of the bellows and also reducing the transmission of vibration.

In addition, since the bellows 102 and the suction connection pipe 104 are not in contact with or connected to each other, the suction connection pipe 104 is inserted into the bellows 102, so that the sucked gas is already in the bellows 102 after coming out of the suction connection pipe, and thus can enter the suction muffler 100 along the bellows 102, thereby reducing the gas from entering the space between the casing of the compressor 20 and the suction muffler 100. In other words, the structure in which the other end of the suction connection pipe 104 protrudes into the bellows 102 is advantageous to improve the suction efficiency of the suction structure 10.

It should be noted that the other end of the suction connection tube 104 protrudes into the bellows 102, that is, there is no connection or contact between the suction connection tube 104 and the bellows 102. Since the two are not in contact or connected, when the compressor 20 is in operation, the pulling force between the suction connection pipe 104 and the bellows 102 caused by vibration can be reduced, which is beneficial to improving the stability and reliability of the fixing of the bellows and also reducing the transmission of vibration.

The suction communicating pipe 104 is spaced apart from the bellows 102 in the radial direction, so that when the compressor 20 vibrates during operation, the possibility of collision therebetween is reduced, thereby reducing noise generated by the collision.

More specifically, the distance between the outer wall of the suction communication tube 104 and the inner wall of the bellows tube 102 is 2mm to 3mm, for example, any one of 2mm, 2.2mm, 2.5mm, 2.8mm, and 3 mm.

The distance between the outer wall of the air suction communicating pipe 104 and the inner wall of the corrugated pipe 102 is limited to 2mm to 3mm, which is beneficial to enabling the corrugated pipe 102 and the air suction communicating pipe 104 to have a larger distance therebetween and reducing noise generated by impact when the compressor 20 works. In addition, the distance between the intake communicating pipe 104 and the bellows 102 is set to the millimeter level, and the space occupied is small, which is advantageous for realizing the compact design of the compressor 20.
