Figure 18 This is an electrical control schematic diagram of the second pressure relief mechanism according to the seventh embodiment of this application, as shown below. Figure 17 and Figure 18 As shown, the pressure relief seat 31 has a third opening 302 communicating with the pressure relief seat 301. The second pressure relief mechanism includes a second pressure relief cover 37 and a third actuator 38. The second pressure relief cover 37 is flip-connected to the pressure relief seat 31 and covers the third opening 302. The drive shaft of the third actuator 38 is connected to the second pressure relief cover 37. The third actuator 38 drives the second pressure relief cover 37 to flip away from the pressure relief seat 31 to open the third opening 302. When the second pressure relief cover 37 covers the third opening 302, the second pressure relief cover 37 can close the third opening 302 to prevent air leakage. When the third actuator 38 drives the second pressure relief cover 37 to flip away from the pressure relief seat 31 to open the third opening 302, the third opening 302 connects to the external environment and the pressure relief seat 301, allowing for exhaust and pressure relief.

[0161] Optionally, the third drive 38 may be, for example, a motor, but is not limited thereto.

[0162] Optionally, the pressure relief seat 31 is a cylindrical structure with openings at both the upper and lower ends. The upper end of the pressure relief seat 31 is a third opening 302, and the lower end of the pressure relief seat 31 is a fourth opening 304. The cover 12 is provided with a vent 121, and the vent 102 passes through the vent 121. A sealing ring 122 is connected to the end of the vent 121 away from the cover 12. The lower end of the pressure relief seat 31 is connected to the sealing ring 122. For the fitting structure of the sealing ring 122 and the pressure relief seat 31, please refer to the fitting structure of the sealing ring 122 and the exhaust seat 13 in the first embodiment, which will not be repeated here.

[0163] Optionally, the second control system 34 is electrically connected to the second pressure sensor 33 and the third driver 38 respectively. The second control system 34 can collect the signal detected by the second pressure sensor 33 and control the third driver 38 to start or stop according to the detection result.

[0164] Eighth embodiment

[0165] The exhaust structure of this embodiment is roughly the same as that of the fifth embodiment, except that the second pressure relief mechanism is different.

[0166] Optionally, Figure 19 This is a partial structural schematic diagram of the exhaust structure according to the eighth embodiment of this application. Figure 20 This is an electrical control schematic diagram of the second pressure relief mechanism according to the eighth embodiment of this application, as shown below. Figure 19 and Figure 20 As shown, a ventilator 121 is provided on the cover 12, and a vent 102 passes through the ventilator 121. The second pressure relief mechanism includes a third pressure relief cover 39 and a fourth actuator 40. The third pressure relief cover 39 is rotatably connected to the ventilator 121 and covers the opening of the ventilator 121. The drive shaft of the fourth actuator 40 is connected to the third pressure relief cover 39. The fourth actuator 40 drives the third pressure relief cover 39 to rotate away from the ventilator 121 to open the opening of the ventilator 121. When the third pressure relief cover 39 covers the opening of the ventilator 121, the third pressure relief cover 39 can close the opening of the ventilator 121 to prevent air leakage. When the fourth actuator 40 drives the third pressure relief cover 39 to rotate away from the ventilator 121 to open the opening of the ventilator 121, the opening of the ventilator 121 connects the external environment with the vent 102, and at this time, exhaust pressure relief can be performed. In this embodiment, the vent 121 does not have an exhaust seat 13, which makes the structure simpler and easier to install than the above embodiments, and can reduce manufacturing costs.

[0167] Optionally, the fourth drive 40 may be, for example, a motor, but is not limited thereto.

[0168] Optionally, the second control system 34 is electrically connected to the second pressure sensor 33 and the fourth driver 40 respectively. The second control system 34 can collect the signal detected by the second pressure sensor 33 and control the fourth driver 40 to start or stop according to the detection result.
