A pressure relief one-way valve cavity 4521 is provided in the pressure relief channel 452, and a pressure relief one-way valve 4522 is provided in the pressure relief one-way valve cavity 4521. The pressure relief one-way valve 4522 is limited in the pressure relief one-way valve cavity 4521 by a pressure relief spring fixing plug 4523. The air intake channel 451 The front cover 44 is connected to one end of the combined valve body 45, and the front cover 44 is connected to the air intake portion 1 through the air pipe 28. The clamp 46 and the valve needle 47 are arranged in the combined valve body 45. The rear cover 49 is connected to the other end of the combined valve body 45. A valve needle return spring 48 is arranged between the valve needle 47 and the combined valve body 45.

[0034] The gas extraction assembly 2 includes: a button 21, a button return spring 22, a primary pressure rod 23, a secondary pressure plate 24, a gas extraction valve core 25, and a gas cylinder connection seat 26. The gas extraction valve core 25 is embedded in the gas cylinder connection seat 26, the secondary pressure plate 24 is connected to the gas cylinder connection seat 26, the secondary pressure plate 24 contacts the gas extraction valve core 25, the primary pressure rod 23 contacts the secondary pressure plate 24, the button 21 contacts the primary pressure rod 23, the button return spring 22 is sleeved and connected to the button 21, the gas cylinder connection seat 26 is connected to the front cover 44 through the air pipe 28, the gas extraction valve core 25 is sleeved with: a first sealing ring 251, and the gas cylinder connection seat 26 is provided with: a first side wall 261;

[0035] The working steps and principles of the utility model from inflating to releasing pressure and returning to the reset state are as follows:

[0036] When the air extraction valve core 25 extracts air, as the button 21 is pressed, the air extraction valve core 25 is pressed down into the high-pressure gas cylinder, so that the high-pressure gas is released into the gas cylinder connecting seat 26. At this time, the first sealing ring 251 and the first side wall 261 are tightly pressed and sealed. The high-pressure gas released into the gas cylinder connecting seat 26 can only enter the front cover 44 through the air pipe 28, and then enter the air inlet channel 451 from the clamp 46. The high-pressure gas presses the inlet check valve 4312 through the inlet check valve cavity 4311. 431 and the water-immersed air-inflating pipe 7 enter the liquid in the water bottle 8. At this time, the air pressure at the end of the pressure relief passage 452 of the pressure relief one-way valve 4522 is greater than the air pressure at the pressure relief port 432, so the pressure relief port 432 is not connected to the pressure relief passage 452. The gas overflowing from the liquid in the water bottle 8 enters the pressure limiting valve cavity air port 433 and then enters between the rear cover 49 and the valve needle 47 through the pressure limiting valve cavity passage 453. As the high-pressure gas injected into the water bottle 8 continues to increase, the pressure between the rear cover 49 and the valve needle 47 increases. The air pressure between the rear cover 49 and the valve needle 47 increases continuously. When the air pressure between the rear cover 49 and the valve needle 47 increases to a certain value, the valve needle 47 will move closer to the clamp 46. The valve needle 47 blocks the clamp 46 and limits the pressure in the water bottle from continuing to rise. After releasing the button, the air extraction valve core 25 leaves the high-pressure gas cylinder, the first sealing ring 251 and the first side wall 261 are not sealed, and the air pipe 28 is connected to the external space. At this time, the air pressure at the end of the pressure relief channel 452 of the pressure relief one-way valve 4522 is less than the air pressure at the pressure relief port 432. The valve 4522 is compressed upward by the air pressure in the water bottle 8. At this time, the pressure relief port 432 is connected to the pressure relief channel 452, and the high pressure in the water bottle 8 is released to the external space. After the pressure release is completed, the valve needle 47 is reset under the action of the valve needle reset spring 48, the air inlet one-way valve 4312 is reset to block the air inlet channel 451, and the pressure relief one-way valve 4522 is reset to block the pressure relief spring fixing plug 4523. At this time, the air pressure in the water bottle 8 is the same as the air pressure of the external environment and can be safely removed from the machine.

[0037] Preferably, the pumping assembly 4 is installed in the pumping section support standpipe 64 .

[0038] Preferably, the air intake portion 1 comprises: an air intake component 2 and an air intake portion supporting vertical pipe 62 , the air intake component 2 is installed in the air intake portion supporting vertical pipe 62 , and the air intake portion supporting vertical pipe 62 is connected to the base 61 .

[0039] Preferably, the air intake section support riser 62 is connected to the air pump section support riser 64 via a transverse connecting pipe 63 .

[0040] The utility model realizes the integrated air intake, exhaust and pressure limiting functions by setting a water bottle interface upper cover 43 with multiple interconnected air passages and a combined valve body 45 as the main body, thereby reducing the probability of air leakage and the complexity of assembly. Through the structural design of the above components, the air path system of the entire bubble water machine is effectively sealed and controlled, greatly reducing the possibility of gas leakage.
