DETAILED DESCRIPTION

[0047] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

The fixed scroll 110 and the movable scroll 120 cooperate with each other, and the movable scroll 120 can move relative to the fixed scroll 110, thereby realizing the compression and discharge of the refrigerant.

[0051] When the movable scroll 120 moves to a disengaged position with the stationary scroll 110, the movable scroll 120 and the stationary scroll 110 form an exhaust chamber 130 and a first compression chamber 140. The first compression chamber 140 is adjacent to the exhaust chamber 130. When the movable scroll 120 moves to a disengaged position with the stationary scroll 110, it can be understood as the position where the volume of the exhaust chamber 130 is the smallest. At the next moment, the exhaust chamber 130 will be connected to the first compression chamber 140, thereby compressing the refrigerant again, until the movable scroll 120 moves to a disengaged position with the stationary scroll 110 again, completing the compression of the refrigerant.
