In this embodiment, a third vent hole 30 is arranged in the fifth mounting seat 25 at a position corresponding to the third ventilation chamber 3. The first pressing chamber 18 is connected to the third ventilation chamber 3 through a one-way ventilation valve core. The first ventilation hole 20 is arranged in the fifth mounting seat 25.

The fixed section 34 is fixedly installed on the sub-valve seat 32, and the sealing section 35 covers the port of the main valve seat 31 facing the closed air bag 29.

[0028] The fourth mounting seat 23 mentioned above is provided with an open airbag 36, and a plurality of ventilation holes 37 are provided on the open airbag 36. The second pressing cavity 19 is arranged in the open airbag 36, and the second pressing cavity 19 is connected with the fourth ventilation cavity 4 through a one-way ventilation valve core, and the second ventilation hole 21 is arranged in the sixth mounting seat 26; a fourth ventilation hole is arranged at a position corresponding to the fourth mounting cavity in the sixth mounting seat 26, and a pressing member for controlling the on and off of the one-way ventilation valve core in the fourth ventilation cavity 4 is installed in the middle of the open airbag 36, and its structure is as follows: a guide seat 38 is arranged at the fourth ventilation hole in the sixth mounting seat 26, and the guide seat 38 is provided with a through hole 39 communicating with the fourth ventilation hole, and a pressing seat 40 is arranged in the middle of the open airbag 36, and the pressing member includes a pressing column 41, one end of the pressing column 41 is installed on the pressing seat 40, and the other end extends to the corresponding one-way ventilation valve core.

[0029] A pillow inflation and deflation device disclosed in the present embodiment has the following implementation principle: when air is taken in, the gas enters the second pressing chamber 19 from the ventilation hole 37 of the open airbag 36, and then enters the second pressing chamber 19 through the second ventilation hole 21, the sixth ventilation chamber 28, the fifth ventilation chamber 27, and the first ventilation hole 20 in sequence. When the gas passes through the one-way ventilation valve flap at the first ventilation hole 20, the gas can pass through the gap between the sealing section 35 and the inclined end surface 33. When the air pressure is relatively high, the gas can also lift the sealing section 35 to a certain height, so that the distance between the sealing section 35 and the port of the valve main seat 31 facing one end of the closed airbag 29 increases; after the gas enters the second pressing chamber 19, the closed airbag 29 is pressed, and the air pressure of the gas causes the one-way ventilation valve core in the third ventilation chamber 3 to open a certain gap, so that the gas enters the third ventilation chamber 3 and then escapes through the ventilation nozzle 12. When the closed airbag 29 is pressed, the sealing section 35 will be in a completely closed state due to the air pressure, so that it is close to the port of the valve main seat 31 facing one end of the closed airbag 29. Therefore, the gas can only pass through the one-way ventilation valve core at the third ventilation chamber 3. At the same time, since the one-way ventilation valve core in the fourth ventilation chamber 4 is in a normal state, the gas can only be discharged through the ventilation nozzle 12; when deflated, the gas enters the third ventilation chamber 3 from the ventilation nozzle 12. Since the one-way ventilation valve core in the third ventilation chamber 3 is in a normal state, the gas can only enter the first ventilation chamber 1 through the first ventilation port 14, and then pass through the first air channel 5 and the second ventilation chamber 2 in turn to reach the fourth ventilation chamber 4, and then by pressing the open airbag 36, the pressing column 41 is used to open the one-way ventilation valve core in the fourth ventilation chamber 4, so that the gas can reach the second pressing chamber 19 and then discharge.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
