The switching power supply 100 may be a Pulse Width Modulation (PWM) power supply. The switching power supply 100 changes the duty ratio of the output power supply according to different level signals input by the controller 1. The duty cycle is the ratio of the period time occupied by the high level to the whole period time, so that the duration of the high level is different if the duty cycle is different. The larger the duty ratio, the longer the high level continues per unit time, the longer the opening time of the air inlet means 2, and the larger the amount of air discharged to the foam-generating chamber 3. The smaller the duty ratio, the shorter the high level duration per unit time, the shorter the opening time of the air inlet means 2, and the smaller the discharge amount to the bubble generation chamber 3.

The first spring-loaded check valve 53 flows from the foaming liquid cartridge 4 to the liquid suction device 5, and the second spring-loaded check valve 54 flows from the liquid suction device 5 to the foam generation chamber 3. When the first spring-type one-way valve 53 is closed, the foaming liquid box 4 and the liquid suction device 5 are separated, and when the first spring-type one-way valve 53 is opened, the foaming liquid box 4 and the liquid suction device 5 are communicated. The second spring-type check valve 54 separates the liquid suction device 5 from the foam generation chamber 3 when closed, and communicates the liquid suction device 5 with the foam generation chamber 3 when opened. Therefore, the first spring-loaded one-way valve 53 and the second spring-loaded one-way valve 54 will completely enclose the pipetting device 5 when closed, so that the fluid in the pipetting device 5 is completely isolated from the outside when not in use, and drying up is avoided. The pipetting means 5 are preferably liquid pumps. When the fluid in the liquid pump is not used, the internal pressure and the external pressure of the liquid pump are consistent, so that the pressure valve is closed, the liquid pump is completely isolated from the outside, and the drying is avoided. When the liquid pump starts to work, the pressure difference caused by the liquid pump pushes the pressure valve to be opened, and the fluid in the liquid pump is communicated with the outside so as to convey the foaming liquid.
The water adding device 7 is preferably a water pump. The water tank 6 is communicated with the foam generating chamber 3 sequentially through the first water supply pipe 71, the water supply device 7, and the second water supply pipe 72. The water adding device 7 sucks water from the water tank 6 through a first water adding pipe 71 and supplies water to the bubble generating chamber 3 through a second water adding pipe 72. A third spring type one-way valve 73 is fixedly arranged in the second water adding pipeline 72. The third spring-loaded check valve 73 flows from the water adding device 7 to the foam generating chamber 3. The third spring type one-way valve 73 is closed to separate the water adding device 7 from the foam generating cavity 3, and the third spring type one-way valve 73 is opened to communicate the water adding device 7 with the foam generating cavity 3. Therefore, when the water pump does not work, the water adding flow path is stably blocked by the third spring type one-way valve 73 under the action of the one-way valve spring, and the series flow of liquid is avoided.
The air intake means 2 is preferably an air pump. The air intake means 2 sucks the atmosphere and outputs air from the air intake port 23 through the air intake duct 21, thereby supplying air to the foam-generating chamber 3. A fourth spring type check valve 22 is fixedly arranged in the air inlet pipeline 21. The fourth spring-loaded check valve 22 flows from the air inlet means 2 to the foam-generating chamber 3. The fourth spring type one-way valve 22 separates the air inlet device 2 from the foam generating cavity 3 when closed, and the fourth spring type one-way valve 22 communicates the air inlet device 2 with the foam generating cavity 3 when opened. Therefore, when the air pump does not work, the air inlet channel is stably blocked by the fourth spring type check valve 22 under the action of the check valve spring, and the series flow of liquid is avoided.
