Specifically, the cylinder 13 limits 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 first-stage foaming frame 121 is fixedly connected with the mixing cover 112 of the mixing part 11, so that the driving module 123 can drive the mixing part 11 and the first-stage foaming frame 121 to reciprocate up and down at the same time, and the movement is similar to the movement of pump work.

As shown in fig. 6, the foaming component further includes a secondary foaming device 122, the secondary foaming device 122 is installed at the foam outlet 1213, and the mixture enters the primary foaming frame 121 and then enters the secondary foaming device 122 to complete the whole foaming process; foaming is carried out in the first-stage foaming frame 121, and further foaming is carried out in the second-stage foaming device 122, so that sufficient foaming operation is ensured.

As shown in fig. 11, in a preferred embodiment, the driving module 123 includes a driving motor 1231, a crank 1232, a rocker 1233; the driving motor 1231 drives the crank 1232 to rotate, the crank 1232 drives the rocker 1233 to rotate, and the other end of the rocker 1233 is hinged to the first-stage foaming frame 121, so that the driving module 123 drives the first-stage foaming frame 121 and the mixing part 11; the rocker 1233 is hinged to the connecting end 1212 of the first-stage foaming frame 121, and when the crank 1232 drives the rocker 1233 to move, the rocker 1233 generates a force acting upward and downward on the first-stage foaming frame 121 to drive the first-stage foaming frame 121 to move upward and downward, and the driving motor 1231 is fixedly mounted on the housing 3; the crank 1232 is driven by the driving motor 1231, so that the whole device can foam continuously, the driving motor 1231 stops rotating, the foaming can be stopped, and the foam can be conveniently and automatically produced.

It should be noted that the common reciprocating driving device, such as an air cylinder, can also achieve the operation of driving the primary foaming frame 121 to reciprocate up and down in the present invention, but since the stroke of the air cylinder is fixed, it is difficult for the air cylinder to adjust the amount of the mixed liquid obtained in the mixing part 11, and thus the volume of the foam that can be pumped out, and in the preferred embodiment, the crank and the connecting rod are replaced to adjust the amount of the water-liquid-air mixture obtained per rotation of the motor, and thus the volume that can be pumped out in unit time.

The opposite side that link 1212 on the one-level foaming frame 121 corresponds drive module 123 sets up balanced module, wherein including crank 1232, rocker 1233 in the balanced module, crank 1232 in the balanced module, rocker 1233 rotate along with one-level foaming frame 121 up-and-down motion, its motion trajectory is unanimous with drive module 123, through setting up balanced module, the power that makes one-level foaming frame 121 up-and-down motion obtains balancedly, can not be to a lopsidedness, thereby make one-level foaming frame 121 motion more stable.

The working process of the foaming device mainly comprises the following steps: when the device is operated, the driving motor 1231 rotates to make the first stage foaming rack 121 drive the mixing part 11 and the like to move up and down. When the first-stage foaming frame 121 moves downwards, the mixing part 11 also moves downwards, the sealing ring 1115 is clamped above the plunger on the mixing part 11 under the action of friction force, the opening 1114 is used for water and hand sanitizer in the outer cavity to enter, and the check valve 133 in the cavity is tightly attached to the water inlet below the cavity due to the action of pressure, so that the water and the hand sanitizer cannot flow downwards. The gas is pushed by the one-way gas inlet film 125 because the compressed air pressure of the air pressure cavity 135 is increased, so that the gas is prevented from overflowing from the air hole 1215, and the peripheral outer wall is sealed by the first-stage foaming frame 121 and the inner wall of the cylinder body 13, so that the gas can only be mixed with the mixed liquid by pushing the elastic sealing film to the gap above the mixing cover 112, and then enters the first-stage foaming frame 121, and the mixed liquid enters the second-stage foaming device 122 after entering the first-stage foaming frame 121, thereby completing the whole foaming process.

When the first-stage foaming frame 121 moves upwards, the mixing part 11 is fixedly connected with the first-stage foaming frame 121 and moves downwards, the sealing ring 1115 slides to the position of the opening 1115 on the plunger under the action of friction force to close the opening 1114 for water and liquid soap in the cavity to enter, the pressure cavity in the cavity is reduced, the one-way valve 133 is not attached to the cavity, and the water and liquid in the liquid storage bin 3 are pressed into the cavity from a gap between the one-way valve 133 and the cavity. The gas is stretched by the gas pressure cavity 135, the gas pressure of the gas pressure cavity 135 is reduced, and the elastic sealing film on the gap above the mixing cover 112 is sucked, so that the space between the first-stage foaming frame 121 and the mixing part 11 is sealed, the gas is limited from entering, the gas can only suck the one-way gas inlet film 125 down by negative pressure, the one-way gas inlet film 125 moves downwards, the gas inlet hole 1215 is exposed, and the gas enters the gas pressure cavity 135 from the gas inlet hole 1215 to prepare for the next downward movement of the first-stage foaming frame 121.

The invention provides a mixing pump capable of adjusting solution ratio, a mixed solution foaming mechanism and a hand washing machine.A water and a liquid are pumped by pressing a mixing part, and a time difference exists between the water and the liquid pumped by a built-in time delay module, and the time delay module can be adjusted to meet the requirement of adjusting the time difference between the water and the liquid sucked by the mixing part, so that the mixing ratio of the water and the liquid can be adjusted; the primary foaming frame is driven by the driving module to drive the mixing part, so that water and liquid mixing and foaming are performed simultaneously, and the foaming process is simplified; the inner wall of the first-stage foaming frame is provided with an air inlet grid, so that gas and liquid are mixed more fully; the periphery of the first-stage foaming frame is provided with air inlet holes which are matched with the one-way air inlet film, so that air cannot overflow when the first-stage foaming frame moves downwards, and air can be sucked when the first-stage foaming frame moves upwards; the gas is limited to overflow through the matching of a closed curve arranged on the outer side of the primary foaming frame and the inner wall of the cylinder body; the volume of the water-liquid-gas mixture obtained by adjusting each turn of the motor through the replaceable crank and the replaceable connecting rod, and further the volume which can be pumped out in unit time is adjusted; the invention has simple structure and convenient use, and can isolate the water liquid from the air pressure cavity by arranging the isolation layer, thereby ensuring the foaming quality formed by gas-liquid ratio.
