Technical Field

[0001] The invention belongs to the field of daily necessities, and in particular relates to a mixing pump capable of adjusting solution ratio, a mixed liquid foaming mechanism and a hand sanitizer. Background Art

[0002] Hand sanitizer is a common daily necessity. It is not as sticky as unmixed hand sanitizer and needs to be mixed with water to foam for cleaning. However, in daily life, water is needed to foam the hand sanitizer, which is time-consuming and laborious. Currently, hand sanitizer mixed with water is often foamed before use, which saves users the work of foaming and achieves the purpose of washing and disinfecting.

[0003] There are two devices with similar functions to this product: a manual press-type foaming device and an electric diaphragm pump-type foaming device. However, these devices currently on the market have the following major drawbacks: they cannot foam unmixed, viscous hand sanitizer. These hand sanitizers are pre-mixed, resulting in low cost-effectiveness and being completely affected by the concentration of the hand sanitizer. They also lack the ability to self-mix water and liquid, making them inoperable if you buy unmixed hand sanitizer directly. Summary of the Invention

[0013] Preferably, the cavity on the cylinder body is communicated with a container for storing water or liquid, and the plunger reciprocates in the cavity, so that the water or liquid enters the water or liquid channel in the plunger.

[0014] Preferably, the second plunger among the plungers is slidably connected to the mixing portion, a gap is provided between the delay module and the second plunger, and the first plunger among the plungers is mounted on the mixing portion;

[0015] When the mixing part is pressed, the first plunger moves relative to the second plunger, and the mixing part moves until the delay module collides with the second plunger, and then the two plungers move simultaneously, so that a time difference is formed between the movements of the two plungers.

[0016] Preferably, the delay module includes an adjusting column, which is threadably connected to the mixing portion. The gap between the delay module and the second plunger is adjusted by rotating the adjusting column.

[0017] Preferably, a resetting elastic element is provided between the second plunger and the cylinder body, and after the delay module releases the conflict with the second plunger, the elastic element rebounds, causing the second plunger to reset.

[0018] On the other hand, a mixed liquid foaming mechanism is also provided, including a foaming mechanism body, the foaming mechanism body including the mixing pump and foaming component as mentioned above, the mixed liquid outlet on the mixing part is connected to the foaming component, so that the mixed liquid in the mixing part passes into the foaming component for foaming.

[0019] Preferably, the foaming component includes a first foaming frame, and the first foaming frame and the cylinder body form an air pressure chamber;

[0020] The first foaming frame and the cylinder body move relative to each other, so that the air pressure chamber is compressed, thereby pressing air into the first foaming frame to contact the mixed liquid.

[0021] Preferably, the foaming component further includes a driving module, which drives the first foaming frame to compress the air pressure chamber, and then the first foaming frame drives the mixing part to suck water and liquid to form a mixed liquid.

[0022] Preferably, an isolation layer is provided on the periphery of the volume cavity of the cylinder body, the outer side of the isolation layer is the air pressure cavity, and the inner side is used to guide the movement of the mixing part.

[0023] On the other hand, a hand washing machine is provided, comprising the mixed liquid foaming mechanism as described above.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention provides a mixing pump with adjustable solution ratio, which includes a cylinder body, a mixing part, and a delay module. By pressing the mixing part to suck water and liquid, there is a time difference between the water and liquid sucked due to the built-in delay module.

[0055] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0056] like Figure 5 As shown, in a preferred embodiment, a hand-washing machine comprises a foaming mechanism body 1, a shell 2 and a liquid storage tank 3, wherein a partition is provided in the liquid storage tank 3, which divides the liquid storage tank 3 into two independent liquid storage spaces by the partition, and the two liquid storage spaces respectively contain unproportioned hand soap and clean water, and the shell 2 is coated on the outer periphery of the foaming mechanism body 1 to form a protective layer of the foaming mechanism body 1. At the same time, the shell 2 and the liquid storage tank 3 are connected to form a whole, so that the shell 2 and the liquid storage tank 3 are sealed, thereby preventing the water in the liquid storage tank 3 from being contaminated by impurities in the external environment; Figure 1 As shown, the foaming mechanism body 1 includes a mixing pump and a foaming component. The mixing pump includes a mixing part 11. The water in the liquid storage tank 3 is sucked into the mixing part 11 in the mixing pump by the mixing pump for mixing to form a mixed liquid in a certain ratio. The formed mixed liquid is passed into the foaming component by the mixing part 11. The mixed liquid in the foaming component forms foam, thereby completing the solution mixing and performing the foaming operation. The unproportioned hand soap can be directly purchased for self-mixing and foaming. It is suitable for different types of hand soaps, has high practicality, and is easy to use. In this preferred embodiment, water and liquid are hand soap and clean water respectively (hereinafter, the two liquids separated from the unproportioned hand soap and clean water are collectively referred to as water and liquid). Figure 9 As shown, the mixing pump in the present invention is not limited to mixing hand soap and clean water. Two miscible liquids can use the mixing pump to mix solutions in the mixing chamber 1111 in the mixing pump.

[0057] like Figure 6 As shown, specifically, the mixing pump also includes a cylinder body 13, which is used to connect the mixing part 11 with the liquid storage tank 3 for holding and releasing water, and the water pressure is pressed into the mixing part 11 by the water-liquid passage formed by the cylinder body 13 and the mixing part 11 and the air pressure difference between the outside world; further, a water and liquid holding cavity is provided in the cylinder body 13, and the cavity is connected to the liquid storage tank 3 by a connecting pipe 14. A one-way valve 134 is provided at one end of the cavity near the connecting pipe 14, so that the water and liquid in the liquid storage tank 3 can only be pressed into the liquid holding cavity from the liquid storage tank 3, limiting the water and liquid in the cavity from flowing back into the liquid storage tank 3. At the same time, further, one end of the connecting pipe 14 is connected to the cavity, and the other end extends into a position near the bottom of the liquid storage tank 3, so as to facilitate the complete extraction of the water in the liquid storage tank 3; at the same time, the connecting pipe 14 and the cylinder body 13 are detachably connected for easy replacement.

[0058] like Figure 1-3 As shown, in a preferred embodiment, the mixing section 11 includes a mixing chamber body 111, a plunger is provided on the mixing chamber body 111, a channel for water and liquid movement is provided in the plunger, an opening 1114 is opened on the side wall of the plunger to connect the cavity and the channel, and a slidable sealing ring 1115 is provided on the mixing section 11, the sealing ring 1115 slides on the plunger, and the outer wall of the sealing ring 1115 is pressed against the inner wall of the cavity; the sealing ring 1115 forms a closed water-liquid passage between the mixing section 11 and the cylinder body 13;

[0059] The mixing portion 11 reciprocates relative to the cylinder body 13, and the sealing ring 1115 is used to open and close the opening 1114, so that the water in the liquid storage tank 3 is sucked into the accommodating cavity, and the water in the accommodating cavity is pressed into the channel in the plunger through the opening 1114. Finally, the water and liquid are mixed in the mixing cavity 1111.

[0060] Its working summary includes: the mixing part 11 reciprocates relative to the cylinder body 13, thereby compressing and stretching the air in the fixed volume liquid chamber to form a vacuum (negative pressure), and generating a pressure difference with the external atmospheric pressure at the one-way valve 134 and the opening 1114. Under the action of the pressure difference, the water in the liquid storage tank 3 is hydraulically (sucked) into the liquid chamber and then discharged from the opening 1114.

[0061] Specifically, the plunger includes a first plunger 1112 and a second plunger 1113; a first cavity 131 and a second cavity 132 for holding water are provided at positions corresponding to the first plunger 1112 and the second plunger 1113 on the cylinder body 13, so that the first plunger 1112 and the second plunger 1113 extend into the first plunger 1112 and the second plunger 1113 respectively; in a preferred embodiment, the first plunger 1112 and the first cavity 131 are used to suck hand soap, and the second plunger 1113 and the second cavity 132 are used to suck clean water. The connecting pipe 14 connects the liquid storage tank 3 and the mixing pump, and the connecting pipe 14 includes a water suction pipe and a liquid suction pipe, which respectively extend into the clean water space and the hand soap space in the liquid storage tank 3.

[0062] Furthermore, an opening 1114 is formed on the side wall of the plunger, and a sealing ring 1115 is sleeved on the side wall of the plunger. The sealing ring 1115 slides relative to the outer wall of the plunger, so that the sealing ring 1115 blocks the opening 1114, thereby restricting the flow of clean water or hand soap from the plunger into the mixing section 11. At the same time, the sealing ring 1115 is pressed against the inner wall of the water pipe 132, thereby forming a closed cavity in the chamber, and using air pressure to press clean water or hand soap into the channel in the plunger.

[0063] like Figure 4 As shown, specifically, the mixing part 11 reciprocates up and down, and the mixing part 11 moves up and down once as one cycle. When the mixing part 11 moves upward, the sealing ring 1115 is located in a position blocking the opening 1114. At this time, the volume of the cavity is stretched and increased, and the air pressure inside the cavity is reduced. At this time, the one-way valve 134 is affected by the internal air pressure and deviates upward, so that the one-way valve 134 is in an open state, so that the water and liquid in the liquid storage tank 3 are sucked into the liquid storage cavity; and when the mixing part 11 moves upward, the sealing ring 1115 is located at a position away from the opening 1114, and the opening 1114 is in an open state, the volume of the cavity is compressed, and the pressure inside the cavity is increased, so that the one-way valve 134 is pressed tightly against the cavity, limiting the backflow of water and liquid. Under the influence of pressure, the clean water in the cavity is pressed into the plunger through the opening 1114, thereby completing the process of clean water passing from the liquid storage tank 3 into the mixing part 11.

[0064] In a preferred embodiment, the mixing pump further includes a delay module 15, which includes a cylinder. A gap is provided between the bottom surface of the cylinder and the second plunger 1113, wherein a boss is provided at one end of the cylinder close to the second plunger 1113, thereby increasing the contact area with the second plunger 1113 and making it fit with the second plunger 1113. The delay module 15 is more stable when pushing the second plunger 1113, thereby ensuring stability when sucking the hand sanitizer, thereby ensuring a stable mixing ratio;

[0065] When the mixing part 11 is pressed, the delay module 15 causes the second plunger 1113 and the second cavity 132 to draw clean water later than the first plunger 1112 and the first cavity 131 draw hand soap, so that a time difference is formed in the water and liquid drawing. The delay module 15 can be adjusted to control the length of the time difference in drawing water and liquid and thus adjust the ratio of the mixed liquid.

[0066] Specifically, the first plunger 1112 is installed on the mixing chamber body 111, and the second plunger 1112 is slidably connected to the mixing chamber body 111. At the same time, the clean water channel in the second plunger 1112 is always in a connected state; when the mixing part 11 is pressed, the second plunger 1113 is in a stationary state, and the first plunger 1112 moves relative to the second plunger 1113. The first plunger 1112 and the first cavity 131 are compressed to extract hand washing water. At the same time, the position of the second plunger 1113 and the second cavity 132 remains unchanged;

[0067] When the mixing part 11 moves to the point where the delay module 15 collides with the second plunger 1113, the mixing part 11 pushes the second plunger 1113 to move, causing the two plungers to move simultaneously. The two plungers simultaneously pump water and liquid. At this point, there is a time difference between the movements of the two plungers. Specifically, the pumping time of clean water is less than the pumping time of hand sanitizer, so that the pumping time is proportional to the pumping amount. The delay module 15 is adjustable to adjust the pumping time of clean water, so that the pumping time of hand sanitizer is fixed, and therefore the pumping amount of hand sanitizer is certain. By adjusting the pumping time of clean water, the pumping amount of clean water is adjusted, thereby changing the mixing ratio of clean water and hand sanitizer.

[0068] Furthermore, the delay module 15 includes an adjustment column 151, which is mounted on the mixing chamber body 111. There is a gap between the adjustment column 151 and the second plunger 1113. When the mixing chamber body 111 moves, the adjustment column 151 and the second plunger 1113 come into contact. Then, the mixing chamber body 111 drives the second plunger 1113 to move.

[0069] Among them, the adjusting column 151 is threadedly connected to the mixing chamber body 111. By rotating the adjusting column 151, the gap between the delay module 15 and the second plunger 1113 is adjusted to adjust the time for the adjusting column 151 to conflict with the second plunger 1113, thereby adjusting the amount of clean water sucked.

[0070] In this preferred embodiment, the solution ratio is adjusted by controlling the suction amount of clean water, and the specific structure of adjusting the solution ratio by controlling the suction amount of hand soap is consistent with the mixing pump structure provided in this preferred embodiment. It only needs to be changed to the second plunger 1113 and the second cavity 132 to suck the hand soap. Therefore, the technical solution of using the mixing pump to adjust the suction amount of hand soap should be regarded as another specific implementation scheme of the present invention.

[0071] A reset elastic element 1116 is provided between the second plunger 1113 and the cylinder body 13. When the mixing chamber body 111 returns to motion, the delay module 15 and the second plunger 1113 are released from conflict, and the elastic element 1116 rebounds, causing the second plunger 1113 to reset, reducing the pressure chamber of the second chamber 132 to replenish clean water into the second chamber 132.

[0072] It should be pointed out that a spring is provided between the one-way valve 134 in the first cavity 131 and the first plunger 1113. Since the hand soap is too viscous, the one-way valve in the liquid pipeline 131 cannot reach the specified working position during operation. The elasticity of the spring resets the one-way valve 134 to the working position, making the one-way valve work more stably.

[0073] like Figure 7 、 8 As shown, the foaming component includes a primary foaming frame 121, which is bonded to the mixing part 11 through a sealing film 113; the primary foaming frame 121 and the cylinder body 13 form an air pressure chamber 135, and by compressing the air pressure chamber 135, the gas passes through the sealing film 113 and enters the mixed liquid outlet 1123 of the mixing part 11, and contacts with the mixed liquid to form foam.

[0074] Specifically, refer to Figure 12 As shown, the outer wall of the first-level foaming frame 121 cooperates with the inner wall of the cylinder body 13, thereby limiting the gas from overflowing from the outer wall of the first-level foaming frame 121 and the inner wall of the cylinder body 13. In a preferred embodiment, the outer wall of the foaming frame 121 is provided with a closed curved surface, and the number of the closed curved surfaces is two. The two closed curved surfaces ensure that the outer wall of the first-level foaming frame 121 and the inner wall of the cylinder body 13 are sealed.

[0075] In a preferred embodiment, an isolation layer is provided on the periphery of the cavity of the cylinder body 13, the outer side of the isolation layer is an air pressure cavity 135, and the inner side is used to guide the movement of the mixing part 11. Specifically, a pressure plate 11131 is provided on the outer edge of the second plunger 1113, and the inner side of the isolation layer surrounds the periphery of the cavity, and a closed isolation cavity 134 is formed by the isolation layer and the pressure plate 11131. The elastic element 1116 is provided in the isolation cavity 134, and the pressure plate 11131 of the second plunger 1113 is limited by the inner wall of the isolation layer. The plunger moves in a fixed direction. At the same time, when the plunger is sucking water or liquid in the volume chamber, if the sealing ring 1115 is not airtight, the water or liquid is likely to overflow from the gap of the sealing ring 1115. If there is no isolation chamber 134 formed by the isolation layer, the water or liquid will enter the air pressure chamber 135, thereby reducing the volume of gas in the air pressure chamber 135. At this time, when the air pressure chamber 135 is compressed, the pressure into the first-level foaming frame 121 is reduced, thereby affecting the mixing ratio of gas and liquid, thereby affecting the foaming effect.

[0076] like Figure 10As shown, the mixing section 11 also includes a mixing cover 112, which is connected to the mixing bin body 111 to form a whole, and a receiving portion 1121 is provided at one end of the mixing cover 112 connected to the first-level foaming frame 121, and a mixed liquid outlet 1123 for discharging the mixed liquid is provided on the receiving portion 1121, and a sealing membrane 113 is arranged around the mixed liquid outlet 1123; an air inlet groove 1122 is arranged on the ground of the receiving portion 1121, and the gas in the air pressure chamber 135 passes through the air inlet groove 1122 and the sealing membrane 113 into the mixed liquid outlet 1123; further, the air inlet grooves 1122 are evenly arranged in a circle on the receiving portion 1121, and the gas is evenly entered into the mixed liquid outlet 1123 through the evenly arranged air inlet grooves 1122, so that the gas is fully in contact with the mixed liquid, thereby fully performing the foaming operation.

[0077] In a preferred embodiment, reference Figure 12 As shown, a connecting end 1212 is provided in the first-level foaming frame 121, and a foam outlet 1213 for foam to pass through is opened in the connecting end 1212, and the mixed liquid outlet 1123 extends to the position of the foam outlet 1213 in the connecting end 1212, and an air intake grid 1214 is provided on the inner wall of the foam outlet 1213. The air intake grid 1214 is arranged around the inner wall of the foam outlet 1213, so that the incoming gas is separated by the air intake grid 1214 into multiple airflows that rush into the mixed liquid outlet 1123 and contact with the mixed liquid, thereby ensuring sufficient foaming operation.

[0078] In a preferred embodiment, a plurality of air inlet holes 1215 are provided on the first-level foaming frame 121, and a one-way air inlet membrane 125 is provided on the air inlet hole 1215. When the first-level foaming frame 121 moves downward, the surrounding outer walls are also sealed because the first-level foaming frame 121 and the inner wall of the cylinder body 13 are sealed, and the gas in the air pressure chamber 135 is compressed, so that the pressure in the air pressure chamber 135 increases, and the air pressure lifts the one-way air inlet membrane 125 so that the one-way air inlet membrane 125 covers the air inlet hole 1215, thereby preventing the gas in the air pressure chamber 135 from overflowing from the air inlet hole 1215, and ensuring that the gas can only pass through the sealing membrane 113 and enter the mixed liquid outlet 1123.

[0079] When the first-level foaming frame 121 moves upward, the gas is sucked down the one-way air inlet membrane 125 by the negative pressure due to the negative pressure in the air pressure chamber 135. Since the first-level foaming frame 121 is sealed with the inner wall of the cylinder body 13, the gas can only be sucked down by the negative pressure. Even if the one-way air inlet membrane 125 moves downward, the air inlet hole 1215 is exposed, allowing the gas to enter the air pressure chamber 135, preparing for the next downward movement of the first-level foaming frame 121.

[0080] The primary foaming frame 121 is driven by a driving module 123, so that the primary foaming frame 121 reciprocates, thereby pressing the gas into the primary foaming frame 121;

[0081] The first-level foaming frame 121 is connected to the mixing part 11, so that the driving module 123 drives the first-level foaming frame 121 and the mixing part 11 to move at the same time. The mixing part 11 presses the mixing liquid into the first-level foaming frame 121 through reciprocating motion, thereby completing the foaming operation. A driving module 123 is used to simultaneously drive the first-level foaming frame 121 and the mixing part 11 to mix water and liquid at the same time, and add gas to the mixed liquid in two steps, which saves driving equipment and simplifies the work process, making the foaming operation more efficient.

[0082] Specifically, the cylinder body 13 limits the movement direction of the first-level foaming frame 121, so that the driving module 123 drives the first-level foaming frame 121 to reciprocate up and down; the first-level foaming frame 121 is fixedly connected to the mixing cover 112 of the mixing part 11, which facilitates the driving module 123 to simultaneously drive the mixing part 11 and the first-level foaming frame 121 to reciprocate up and down, performing a movement similar to the work of a pump.

[0083] like Figure 6 As shown, the foaming component also includes a secondary foaming device 122, which is installed at the foam outlet 1213. The mixture enters the primary foaming rack 121 and then enters the secondary foaming device 122 to complete the overall foaming process; foaming is performed in the primary foaming rack 121, and further foaming is performed in the secondary foaming device 122, thereby ensuring sufficient foaming operation.

[0084] like Figure 11 As shown, in a preferred embodiment, the driving module 123 includes a driving motor 1231, a crank 1232, and a rocker 1233; wherein the driving motor 1231 drives the crank 1232 to rotate, and the crank 1232 drives the rocker 1233 to rotate, and the other end of the rocker 1233 is hinged on the primary foaming frame 121, so that the driving module 123 drives the primary foaming frame 121 and the mixing part 11; the rocker 1233 is hinged to the connecting end 1212 on the primary foaming frame 121, and when the crank 1232 drives the rocker 1233 to move, the rocker 1233 generates an upward and downward force on the primary foaming frame 121, driving the primary foaming frame 121 to move up and down, and the driving motor 1231 is fixedly mounted on the shell 3; the crank 1232 is driven by the driving motor 1231, so that the entire device can foam continuously, and when the driving motor 1231 stops, the foaming can be stopped, which is convenient for automatic production of foam.

[0085] It should be pointed out that common reciprocating drive devices such as cylinders can also realize the work of driving the first-level foaming frame 121 to reciprocate up and down in the present invention. However, since the stroke of the cylinder is fixed, it is difficult for the cylinder to adjust the amount of the mixed liquid obtained in the mixing part 11, and thus it is difficult to adjust the volume of the foam that can be pumped out. In this preferred embodiment, the crank and connecting rod can be replaced to adjust the amount of the water-liquid-gas mixture obtained per rotation of the motor, thereby adjusting the volume that can be pumped out per unit time.

[0086] A balancing module is set on the other side of the driving module 123 corresponding to the connecting end 1212 on the first-level foaming frame 121, wherein the balancing module includes a crank 1232 and a rocker 1233. The crank 1232 and the rocker 1233 in the balancing module rotate as the first-level foaming frame 121 moves up and down, and its motion trajectory is consistent with the driving module 123. By setting the balancing module, the force of the up and down movement of the first-level foaming frame 121 is balanced, and it will not tilt to one side, thereby making the movement of the first-level foaming frame 121 more stable.

[0087] The operating process of the foaming device mainly includes the following: when the device is in operation, the drive motor 1231 rotates to cause the primary foaming frame 121 to drive the mixing unit 11 and other components to move up and down. When the primary foaming frame 121 moves downward, the mixing unit 11 also moves downward. The sealing ring 1115 is stuck above the plunger on the mixing unit 11 due to the action of friction. The opening 1114 allows water and hand soap in the outer chamber to enter. At this time, the one-way valve 133 in the chamber is pressed tightly against the water inlet below the chamber due to pressure, preventing the water and hand soap from flowing out. The gas pressure increases due to the compression of the air pressure chamber 135, and the one-way air inlet membrane 125 supports the air hole 1215, preventing the gas from overflowing from the air hole 1215. The surrounding outer walls are also sealed because the first-level foaming frame 121 is sealed with the inner wall of the cylinder body 13. Therefore, the gas can only pass through the elastic sealing membrane that pushes open the gap above the mixing cover 112, and then enter the first-level foaming frame 121 after mixing with the mixed liquid. After entering the first-level foaming frame 121, the mixed liquid enters the second-level foaming device 122 to complete the overall foaming process.

[0088] When the primary foaming frame 121 moves upward, the mixing part 11 is fixedly connected to the primary foaming frame 121, so it also moves downward. The sealing ring 1115 slides to the position of the opening 1115 on the plunger under the action of friction, closing the opening 1114 for the water and hand soap in the cavity to enter. At this time, the pressure cavity in the cavity is reduced, and the one-way valve 133 is no longer tightly attached to the cavity. The water and liquid in the liquid storage tank 3 are pressed into the cavity through the gap between the one-way valve 133 and the cavity. The gas is stretched due to the pressure chamber 135, and the air pressure in the pressure chamber 135 is reduced, which sucks the elastic sealing membrane on the gap above the mixing cover 112, so that the first-level foaming frame 121 and the mixing part 11 are sealed, restricting the entry of gas. The gas can only suck down the one-way air intake membrane 125 through the negative pressure, and the one-way air intake membrane 125 moves downward, exposing the air intake hole 1215, so that the gas enters the pressure chamber 135 through the air intake hole 1215, preparing for the next downward movement of the first-level foaming frame 121.

[0089] The present invention provides a mixing pump with adjustable solution ratio, a mixed liquid foaming mechanism and a hand-washing machine. By pressing the mixing part to suck water and liquid, a built-in delay module creates a time difference between the water and liquid suction. The delay module can be adjusted to meet the time difference between the water and liquid suctioned by the mixing part, thereby adjusting the water-liquid mixing ratio. The driving module simultaneously drives the first-level foaming frame to drive the mixing part, thereby performing water-liquid mixing and foaming simultaneously, simplifying the foaming process. The inner wall of the first-level foaming frame is provided with an air inlet grid to make the gas-liquid mixing more complete. The first-level foaming Air inlet holes are provided around the frame, which cooperate with the one-way air inlet membrane to prevent gas from overflowing when the first-level foaming frame moves downward, and allow gas to be inhaled when the first-level foaming frame moves upward; the closed curve provided on the outer side of the first-level foaming frame cooperates with the inner wall of the cylinder to limit gas overflow; the amount of water-liquid-gas mixture obtained by each rotation of the motor is adjusted by a replaceable crank and connecting rod, thereby adjusting the volume that can be pumped out per unit time; by providing an isolation layer, the water liquid is isolated from the air pressure chamber to ensure the foaming quality formed by the gas-liquid ratio. The present invention has a simple structure and is easy to use.
