As shown in fig. 8, in the second embodiment of the present invention, unlike the first embodiment, a gas guide passage is provided between the fixed scroll 2 and the upper bracket 5. The first connecting seat 102 and the third connecting seat 205 are respectively fixed on the fixed scroll 2 and the upper bracket 5, and the upper bracket 5 is provided with a relief hole 206 for avoiding from the connecting pipe 101 when the movable scroll is engaged to rotate horizontally. The connecting pipe 101 is provided with a spring (an elastic pipe section structure 203) which can stretch and contract, and the spring can rotate along with the movable scroll disk and can simultaneously zoom the length of the connecting pipe 101 so as to meet the moving amount generated by the engagement of the movable scroll disk and the fixed scroll disk.

When the scroll compressor works, a low-pressure refrigerant in the movable scroll 15 passes through the third radial channel 201b and then enters the back pressure cavity 200 of the fixed scroll through the adapter assembly (the first connecting seat 102), the pressure in the pipeline is sealed under the action of the first connecting seat 102 and is slowly led into the back of the fixed scroll, when certain pressure is reached, the sealing assembly is gradually and slowly lifted and attached to the high-low pressure partition plate until the fixed scroll and the high-low pressure partition plate form an exhaust channel, at the moment, the impact between the sealing assembly and the high-low pressure partition plate is relieved, and the floating channel of the sealing assembly is effectively improved, so that the buffering and noise reduction effects are better.

In addition, the two implementation modes meet the requirement that gas is guided to the inside of the back pressure cavity of the static vortex disk through the movable vortex disk, the conventional structural form that the exhaust hole can only be formed in the static vortex disk at present and the gas in the compression cavity is introduced into the back sealing cover is changed, and the implementation method can be used as a new floating sealing form.

The present disclosure also provides an air conditioner including the scroll compressor of any one of the preceding claims.

The above description is only exemplary of the present disclosure and should not be taken as limiting the disclosure, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present disclosure should be included in the scope of the present disclosure. The foregoing is only a preferred embodiment of the present disclosure, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present disclosure, and these modifications and variations should also be regarded as the protection scope of the present disclosure.
