The external atmospheric pressure produces a pressure difference. Under the action of the pressure difference, the water in the liquid storage tank 3 is hydraulically (sucked) into the liquid storage chamber, and then discharged from the opening 1114. The principle of absorbing water is similar to that of pressing the pump head.

As shown in FIG. 6 , specifically, the plunger includes a water inlet end 1112 for introducing clean water and a liquid inlet end 1113 for introducing liquid; the solution chamber of the cylinder 13 includes a water pipe 132 for holding water, a liquid The pipe 131, the water pipe 132, and the liquid pipe 131 correspond to the water inlet end 1112 and the liquid inlet end 1113 one by one; the water inlet end 1112 and the liquid inlet end 1113 are respectively extended into the water pipe 132 and the liquid pipe 131; the connecting pipe 14 includes The water suction pipe 141, the liquid suction pipe 142, the water suction pipe 141 and the liquid suction pipe 142 are respectively connected to the water pipe 132 and the liquid pipe 131, so that the water suction pipe 141 and the liquid suction pipe 142 respectively extend into the clean water space in the liquid storage tank 3 As for the space for holding the hand sanitizer, since the structures on the water pipe 132 and the liquid pipe 131 are similar, only the relationship between the water pipe 132 and the water inlet end 1112 is described below.

When the mixing part 11 moves upward, the sealing ring 1115 is in a position to block the opening 1114, and the volume in the liquid container is stretched to increase. , the air pressure inside the liquid storage chamber decreases. At this time, the one-way valve 134 is shifted upward due to the influence of the internal air pressure, so that the one-way valve 134 is in an open state, so that the clean water in the liquid storage tank 3 is sucked into the liquid storage chamber; During movement, the sealing ring 1115 is located at a position away from the opening 1114. When the opening 1114 is open, the volume in the liquid-accommodating chamber is compressed, and the internal pressure of the liquid-accommodating chamber increases, so that the one-way valve 134 and the water pipe 132 are pressed tightly, restricting The fresh water flows back, and the fresh water in the liquid container is pressed into the opening 1114 under the influence of the pressure, thereby completing the process of clearing the fresh water from the liquid storage tank 3 to the mixing part 11 .

When the foam frame 121 moves downward, the surrounding outer walls are also sealed due to the first-stage foam frame 121 and the inner wall of the cylinder block 13, and the gas in the air pressure chamber 1211 is compressed, so that the pressure in the air pressure chamber 1211 is increased, and the air pressure will be inhaled in one direction. The membrane 125 is lifted so that the one-way gas inlet membrane 125 shields the gas inlet hole 1215, preventing the gas in the air pressure chamber 1211 from overflowing from the gas inlet hole 1215, and ensuring that the gas can only pass through the sealing membrane 113 and enter the mixed liquid outlet 1123.

When the first-stage foaming frame 121 moves upward, the gas is only unidirectionally fed by the negative pressure due to the negative air pressure in the air pressure chamber 1211 and because the first-stage foaming frame 121 and the inner wall of the cylinder 13 are sealed. When the film 125 is sucked down, even if the one-way air inlet film 125 moves downward, the air inlet hole 1215 is exposed, so that the gas enters the air pressure chamber 1211 to prepare for the next time the first-stage foaming frame 121 moves downward.

The foaming portion 12 is driven by a driving module 123, so that the foaming portion 12 reciprocates, thereby pressing the gas into the foaming portion 12;

The foaming part 12 is connected with the mixing part 11, so that the driving module 123 drives the foaming part 12 and the mixing part 11 to move at the same time. A driving module 123 simultaneously drives the foaming part 12 and the mixing part 11 to mix water and liquid at the same time, and adds gas to the mixed liquid in two steps, which saves the driving equipment and simplifies the work process, making the foaming operation more efficient.

Specifically, the cylinder block 13 restricts the movement direction of the first-stage foaming frame 121, so that the driving module 123 drives the first-stage foaming frame 121 to reciprocate up and down; The driving module 123 drives the mixing part 11 and the first-stage foaming frame 121 to reciprocate up and down at the same time, making a movement similar to the operation of a pump.

As shown in Figures 4 and 8, in a preferred embodiment, the drive module 123 includes a drive motor 1231, a crank 1232, and a rocker 1233; wherein, the drive motor 1231 drives the crank 1232 to rotate, the crank 1232 drives the rocker 1233 to rotate, and the crank 1232 drives the rocker 1233 to rotate. The other end of the rod 1233 is hinged on the foaming part 12, so that the driving module 123 drives the foaming part 12 and the mixing part 11; When the rocker 1233 moves, the rocker 1233 produces an upward and downward force on the first-stage foaming frame 121, which drives the first-stage foaming frame 121 to move up and down, and the driving motor 1231 is fixedly installed on the casing 3; the crank is driven by the driving motor 1231 1232, so that the entire device can be continuously foamed, and the driving motor 1231 stops rotating, and the foaming can be stopped, which is convenient for automatic foam production.

It should be pointed out that a common reciprocating driving device such as a cylinder can also realize the work of driving the first-stage foaming frame 121 to reciprocate up and down in the present invention. It is difficult to adjust the volume of the foam that can be pumped out due to the amount of the obtained mixture, but in this preferred embodiment, by replacing the crank and connecting rod, the amount of the obtained water-liquid-gas mixture can be adjusted for each revolution of the motor, Then adjust the volume that can be pumped out per unit time.

A balance module 124 is disposed on the connecting end 1212 of the first-stage foaming frame 121 corresponding to the other side of the drive module 123, wherein the balance module 124 includes a crank 1232 and a rocker 1233, and the crank 1232 and the rocker in the balance module 124 The rod 1233 rotates with the up and down movement of the first-stage foaming frame 121, and its movement track is consistent with the driving module 123.

Inclined, so that the movement of the first-stage foaming frame 121 is more stable.

As shown in Figures 12-14, the working process of the foaming device mainly includes: when the device is working, the driving motor 1231 rotates so that the primary foaming frame 121 drives the mixing part 11 to move up and down. When the first-stage foaming frame 121 moves downward, the mixing part 11 also moves downward, and the sealing ring 1115 is stuck above the water inlet end 1112 and the liquid inlet end 1113 of the mixing part 11 under the action of friction, and the opening is 1114 is for the water and hand sanitizer in the outer water inlet pipe 132 and the liquid pipe 131 to enter. At this time, the one-way valve in the outer water pipe 132 and the liquid pipe 131 is closely attached to the bottom of the pipe due to the pressure, so that water, hand washing Liquid will not flow downwards. Because of the air pressure in the air pressure chamber 1211, the gas resists the one-way air intake film 125 so that the air does not overflow through the air intake hole 1215, and the surrounding outer walls are also sealed because the first-stage foaming frame 121 and the inner wall of the cylinder block 13 are sealed, so The gas can only pass through the opening of the elastic sealing film 113 to the gap above the mixing cover 112, and then enter the primary foaming frame 121 after mixing with the mixed liquid, and the mixed liquid enters the primary foaming frame 121 and then enters the secondary foaming device 122. , to complete the overall foaming process.

When the first-stage foaming frame 121 moves upward, the mixing part 11 is fixedly connected with the first-stage foaming frame 121, so it also moves downward, and the sealing ring 1115 is stuck on the water inlet end of the mixing part 11 under the action of frictional force. 1112. Below the liquid inlet end 1113, close the opening 1114 for the water in the outer water pipe 132, the water in the liquid pipe 131, and the hand sanitizer. The upward movement generates negative pressure, which is lifted from below the pipe, and the spring in the liquid pipe is also overcome by the spring force, so that the water and hand sanitizer are sucked out from the container below. Because of the negative air pressure in the air pressure chamber 1211, the gas absorbs the elastic sealing film 113 on the gap above the mixing cover 112, so that the gas does not enter through the one-way air inlet film 125, and the surrounding outer walls are still caused by the first-stage foaming frame 121 and the The inner wall of the cylinder block 13 is sealed, so the gas can only be sucked down by the one-way intake film 125 through negative pressure. Prepare for the next time the first-stage foaming rack 121 moves downward.
