The fastener 4 is sleeved outside the suction bag 3 and fixed at the bottom end of the conducting piece 5, a liquid cavity 51, an air cavity 52 and a foam cavity 53 are respectively arranged on the conducting piece 5, a plurality of through holes 55 are respectively formed in the bottom surfaces of the liquid cavity 51, the air cavity 52 and the foam cavity 53, the liquid cavity 51 and the air cavity 52 are respectively provided with a first check valve 54 at the bottom end of the through hole 55, each first check valve 54 is correspondingly positioned at the bag opening of the suction bag unit 31, and the foam cavity 53 is positioned at the top end of the through hole 55 and is provided with a second check valve 56. The top cover 6 extends outwards to form a liquid input pipe 61, a foam output pipe 63 and an air input pipe 62 which are communicated with the liquid cavity 51, the air cavity 52 and the foam cavity 53 respectively, a micropore quantity control plug 612 is arranged in the liquid input pipe 61, a liquid through hole 613 is arranged in the middle of the micropore quantity control plug 612, a liquid leakage prevention valve 622 is arranged on the air input pipe 62, and a flow guide pipe orifice 621 is arranged between the air input pipe 63 and the liquid leakage prevention valve 622.

Thus, the liquid input tube 61 is connected to a liquid container for storing liquid (such as soap solution, detergent, etc.) capable of making foam, when the driving motor 1 is operated, the eccentric wheel 11 can be driven to rotate, by utilizing the eccentric hole 111 on the eccentric wheel 11 not being coaxial with the swinging wheel 2, the swinging wheel 2 can regularly and rapidly press the corresponding suction bag unit 31 through the sleeve opening 22 in sequence under the action of the eccentric hole 11, so that when one suction bag unit 31 is pressed, the other suction bag units 31 are in a drawn state (i.e. not pressed), therefore when the suction bag unit 31 under the liquid cavity 51 is drawn from the pressed state, the first check valve 54 under the through hole of the liquid cavity 51 is drawn by the suction bag unit 31, and further the first check valve 54 is far away from the through hole 54 on the liquid cavity 51 (i.e. the through hole 54 on the liquid cavity 51 is opened), the liquid chamber 51 is communicated with the suction bag unit 31 through the through holes, the liquid in the liquid container is sucked into the suction bag unit 31 by the liquid input pipe 61 under the suction force of the suction bag unit 31, and when the suction bag unit 31 positioned below the liquid chamber 51 is pressed, the first check valve 54 positioned below the through holes of the liquid chamber 51 is pressed by the suction bag unit 31, so that the first check valve 54 is pressed and passed through, thereby preventing the sucked liquid from being pushed back, and similarly, air can be sucked from the air input pipe 62, and a plurality of suction bag units 31 are rapidly operated under the action of the driving motor 1, so that the air and the liquid are fully mixed to form foam, enter the foam chamber 53 from the through holes positioned on the foam chamber 53, and finally are output from the foam output pipe 63. The liquid inlet amount when the suction bag unit 31 is drawn can be controlled by the liquid passing hole 613 of the micro-hole control amount plug 612, thereby preventing the produced foam from being not fine and smooth due to excessive liquid, reducing the power of the driving motor 1, reducing the noise generated by the driving motor 1, and is connected to the top end of the liquid container through the guide nozzle 621, so that the air pressure in the liquid container can be supplemented, meanwhile, when the foam pump stops using, the residual foaming liquid in the foam output pipe 63 flows back to the air output pipe 62, the residual liquid can flow back to the liquid container from the diversion pipe orifice 621, and the liquid leakage prevention valve is also used for preventing the residual liquid from overflowing from the pipe orifice of the air input pipe, and then make things convenient for people to use to can solve current foam pump and stop using the problem that the liquid backward flow of remaining foaming formation in the foam output influences its use to air inlet.

It should be noted that the liquid inlet pipe 61, the foam outlet pipe 63, and the air inlet pipe 62 may be made into shapes required by actual products according to the application of the actual products, or may be flexible pipes such as hoses.

In the embodiment of the present invention, the micropore quantity control plug 612 is funnel-shaped from the top to the liquid via hole 613, so as to play a role of diversion and make the liquid enter the liquid via hole 613.

In the embodiment of the present invention, the aperture of the liquid through hole 613 is 0.3-0.7 mm through the test, so that the current required by the driving motor 1 of the foam pump of the present invention is controlled below 0.3 a, and the foam with high quality and fine quality can be produced. Compared with the existing driving motor 1, the liquid input pipe 61 of the driving motor 1 is not provided with the micropore quantity control plug 612, so that in order to manufacture high-quality and fine foam, the control current of the driving motor 1 is required to be 0.5 ampere, even more than 0.7 ampere, therefore, the micropore quantity control plug 612 is used for reducing the liquid entering quantity, the power required for manufacturing the high-quality and fine foam driving motor 1 can be greatly reduced, the power consumption is reduced, the noise generated by the driving motor 1 is further reduced, and the high-quality use experience is provided for people.

In the embodiment of the present invention, the liquid input pipe 61 is located the micropore volume control plug 612 top and still is provided with the pressure reducing valve 611, through pressure reducing valve 611, can prevent liquid in the liquid container when being higher than liquid input pipe 61, cause the utility model discloses liquid pressure excessively advances to spill over in the air output tube 62 when not working, it is required to explain that, when liquid is less than liquid input pipe 61 in the liquid container, can not need pressure reducing valve 611.

The embodiment of the present invention provides a foam net 631 is disposed in the foam output pipe 63, and the foam net 631 can further foam the foam output from the foam output pipe 63, so that the port of the foam output pipe 63 outputs the fine and smooth foam.
