Accordingly, the inclusion in the background section is not an admission of prior art by the applicant.

The inventor researches and discovers that the foaming machine in the prior art has the defect of unsatisfactory foaming effect or has the problem of unsatisfactory foaming after being used for a period of time, wherein one reason is that key parts of the foaming machine such as leakage change the proportional relation of gas-liquid mixing, and the other reason is that a pressure measuring component is influenced by corrosion of liquid in use, so that the pressure measuring accuracy of the foaming machine is reduced, the gas-liquid mixing proportion or the final pressure does not meet the design requirement, and finally the generation effect of foam is not satisfactory. Moreover, the above also affects the operational experience and safety of the foaming machine.

An air inlet hole 202 for gas-liquid mixing is formed in the connection part 202, and the air inlet hole 202 is preferably frustum-shaped, and the smaller end of the air inlet hole faces the inside of the pipette 201. Since the pressure in the bottle body 100 is higher than the pressure in the pipette 201, the foamed cleaning liquid in the pipette 201 (which is a negative pressure) does not leak from the air intake hole 202 due to the pressure difference. As shown in fig. 3 and 4, the bottle cap assembly 200 further includes a safety valve 203 and a manual pressure relief valve 204, wherein the safety valve 203 opens to release pressure when the pressure in the bottle body 100 is greater than or equal to a safety valve trigger pressure value, and the manual pressure relief valve 204 releases the pressure in the bottle body 100 when the bottle body 100 and the bottle cap assembly 200 need to be separated.
