[0042] Example 1

[0043] As mentioned in the background art, as shown in Figures 1-21 The present application proposes a seat pneumatic system controller exhaust device for a car seat 1, the car seat 1 comprising a rear cavity 15, the seat pneumatic system controller exhaust device being arranged in the rear cavity 15, comprising:

[0044] A controller body 2, the controller body 2 comprising a controller shell 21, the controller shell 21 having a first space 22 inside, the controller shell 21 being provided with a plurality of control valve bodies 23, each control valve body 23 having an air inlet and outlet port outside the first space 22 and an air outlet 231 inside the first space 22, the air inlet and outlet port being used for communication with a gas using assembly, the air outlet 231 being used for exhausting the gas in the gas using assembly;

[0045] The controller shell 21 is provided with at least one air exhaust assembly 3, the air outlet 231 communicates with the air exhaust assembly 3, and the air exhaust assembly 3 has an exhaust port 311, which communicates with the space outside the rear cavity 15.

[0046] Specifically, the automobile seat 1 comprises an automobile backrest, which comprises, from front to back, a cover 12, a soft layer 13, a foam 11, a buckle cover 14, a rear cavity 15 formed between the buckle cover 14 and the foam 11, a gas source 18 and a controller body 2 arranged in the rear cavity 15. Optionally, a mounting back plate 17 is arranged in the rear cavity 15, and the gas source 18 and the controller body 2 are arranged on the mounting back plate 17. Optionally, a gas assembly is used as a gas bag 19 for massage or support, which is arranged between the foam 11 and the soft layer 13. The gas bag 19 is in communication with a gas inlet and outlet. The gas source 18 inflates the gas bag 19 through a control valve 23 in the controller body 2. When the gas bag 19 deflates, the gas is discharged through a deflation port 231 to a deflation assembly 3, and then discharged through an exhaust port 311 of the deflation assembly 3 to the outside of the rear cavity 15. Therefore, the working state or service life of the components in the rear cavity 15 is not affected by the excessively high deflation temperature.

[0047] In a preferred embodiment, the controller housing 21 is sealed, and the deflation port 231 is in communication with the deflation assembly 3 through the first space 22.

[0048] The controller housing 21 is sealed to prevent the gas discharged by the gas assembly from being discharged through the gap of the controller housing 21, and to prevent the deflation noise at the deflation port 231 from being transmitted out of the controller housing 21, thereby achieving the purpose of noise reduction.

[0049] In a preferred embodiment, the first space 22 is provided with a gas collecting member 4, the gas collecting member 4 has a gas collecting cavity 42 therein, at least one of the deflation ports 231 is covered by at least one side of the gas collecting member 4, and the gas collecting member 4 is provided with a gas inlet hole corresponding to each of the deflation ports 231 and in communication with the gas collecting cavity 42.
