An exhaust structure 100, a compressor, and a vehicle provided according to some embodiments of the present utility model are described below with reference to fig. 1 to 5.

In one embodiment according to the present application, as shown in fig. 1 and 2, there is provided a discharge structure 100, the discharge structure 100 being used for a compressor including a discharge port 221, the discharge structure 100 including: an exhaust chamber 110 for communicating with the exhaust port 221; an oil component 120 provided in the exhaust chamber 110, the oil component 120 being provided with a first passage 121; the valve assembly 130 is provided in the oil component 120, and is used for opening or closing the first passage 121 and the discharge chamber 110.

The exhaust structure 100 provided by the embodiment of the present utility model includes an exhaust chamber 110, an oil component 120, and a valve assembly 130, specifically, the exhaust structure 100 is used for a compressor, and an exhaust port 221 can communicate with the exhaust chamber 110.

The oil component 120 is disposed in the discharge chamber 110, and it is understood that when the compressor is discharged, high temperature and high pressure gas may carry part of the lubricating oil during discharge. By providing the oil separator 120 in the exhaust chamber 110, the gas carrying part of the lubricating oil flowing through the oil separator 120 can be separated into gas and oil, which is beneficial to increasing the oil return rate and reducing the oil discharge amount, thereby ensuring the stable operation of the compressor.

The oil component 120 is provided with a first channel 121, and it will be understood that, after the high-temperature and high-pressure gas enters the exhaust cavity 110 for gas-oil separation, the high-temperature and high-pressure gas can flow through the first channel 121 and finally be discharged through the air outlet 211 of the housing.

The valve assembly 130 is provided on the oil component 120, and the valve assembly 130 can open or close the first passage 121 to the discharge chamber 110. Specifically, during operation of the compressor, when gas enters the discharge chamber 110 through the discharge port 221, the valve assembly 130 closes the first passage 121 from the discharge chamber 110 due to the low pressure of the gas within the discharge chamber 110.

When the pressure in the discharge chamber 110 reaches a certain pressure, the valve assembly 130 makes the first passage 121 communicate with the discharge chamber 110, and at this time, the gas in the discharge chamber 110 is discharged through the first passage 121 of the oil component 120.

By arranging the valve assembly 130 on the oil component 120 to control the on/off of the first channel 121 and the exhaust cavity 110, exhaust pulsation generated in the exhaust process of the compressor can be effectively reduced, noise of the compressor with the exhaust structure 100 can be reduced, noise of the whole vehicle with the compressor can be reduced, and comfort of the vehicle can be improved.

In this embodiment, it is defined that the oil component 120 is further provided with an opening 122, in particular, the valve assembly 130 is capable of opening or closing the opening 122 of the oil component 120 to open or close the first passage 121 to the drain chamber 110.

Specifically, during operation of the compressor, when gas enters the discharge chamber 110 through the discharge port 221, the valve assembly 130 closes the opening 122 to close the first passage 121 from the discharge chamber 110 due to the low pressure of the gas in the discharge chamber 110.

When the pressure in the discharge chamber 110 reaches a certain pressure, the valve assembly 130 opens the opening 122 to allow the first passage 121 to communicate with the discharge chamber 110 through the opening 122, and at this time, the gas in the discharge chamber 110 is discharged through the opening 122 of the oil component 120 and the first passage 121.

By integrating the valve assembly 130 on the oil component 120 and opening or closing the opening 122 of the oil component 120 through the valve assembly 130, the first channel 121 and the exhaust cavity 110 are controlled to be conducted or cut off, so that exhaust pulsation generated in the exhaust process of the compressor can be effectively reduced, noise of the compressor with the exhaust structure 100 is reduced, noise of a whole vehicle with the compressor is reduced, and comfort of the vehicle is improved.

That is, the valve assembly 130 is integrated in the oil component 120, and the opening 122 of the oil component 120 is opened or closed by the valve assembly 130 to control the connection or disconnection of the first passage 121 and the exhaust chamber 110, so that exhaust pulsation generated in the exhaust process of the compressor can be effectively reduced, noise of the compressor having the exhaust structure 100 can be reduced, noise of the whole vehicle having the compressor can be reduced, and comfort of the vehicle can be improved.
