[0062] 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.

[0063] like Figure 1 、 2 As shown, a water-liquid self-mixing foaming device includes a foaming mechanism body 1, a shell 2 and a liquid storage tank 3, wherein a partition 31 is provided in the liquid storage tank 3, and the partition 31 divides the liquid storage tank 3 into two independent liquid storage spaces, and the two liquid storage spaces respectively contain unproportioned hand soap and clean water (hereinafter, the two liquids separated by unproportioned hand soap and clean water are collectively referred to as water liquid), 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 3 、 4 As shown in Figures 6, the foaming mechanism body 1 includes a pump body, wherein a mixing portion 11 is provided on the pump body, the water in the liquid storage tank 3 is respectively introduced into the mixing portion 11, and mixed in the mixing cavity 1111 of the mixing portion 11 to form a mixed liquid according to a certain ratio, the top of the mixing portion 11 is connected with a foaming portion 12, the mixed liquid formed in the mixing cavity 1111 is introduced into the foaming portion 12, and the mixed liquid in the foaming portion 12 forms foam, thereby completing self-mixing and performing foaming operations. You can directly buy unproportioned hand soap for self-mixing and foaming operations, which is suitable for different types of hand soaps, with high practicality and easy use.

[0064] like Figure 3 、 4 As shown, specifically, the pump body includes a cylinder body 13 and a plunger. The plunger is hollow so that the water can pass into the mixing chamber 1111 of the mixing part 11. The cylinder body 13 is used to connect the mixing part 11 with the liquid storage tank 3 for holding and releasing the water. The water is pressed into the mixing part 11 due to the pressure difference between the water passage formed by the cylinder body 13 and the mixing part 11 and the external air pressure; further, a liquid holding chamber for holding and releasing the water is provided at the bottom of the cylinder body 13. The liquid holding chamber is connected to the liquid storage tank 3 by a connecting pipe 14. Part of the plunger is correspondingly inserted into the liquid holding chamber. A one-way valve 134 is provided at one end of the liquid holding chamber close to the connecting pipe 14, so that the water in the liquid storage tank 3 can only be pressed into the liquid holding chamber from the liquid storage tank 3, limiting The water in the liquid-containing cavity flows back into the liquid storage tank 3, and the plunger is driven by external force to move up and down in the solution cavity, so that the water is sucked into the solution cavity from the liquid storage tank 3, and the water is pressed into the plunger to form a cycle; at the same time, further, one end of the connecting pipe 14 is detachably connected to the pipeline, and the other end is extended 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; by providing a detachable connecting pipe 14, it is convenient to replace. At the same time, in a preferred embodiment, by replacing connecting pipes 14 of different diameters, the flow channel diameter of the connecting pipe 14 is expanded or reduced, the amount of water inlet and / or liquid inlet is adjusted, and then the water-liquid mixing concentration ratio is adjusted.

[0065] like Figure 5 、 6 As shown, in a preferred embodiment, the mixing portion 11 is provided with an opening 1114 for the liquid in the liquid containing chamber to pass through, and the mixing portion 11 is provided with a slidable sealing ring 1115. The outer wall of the sealing ring 1115 is pressed against the inner wall of the liquid containing chamber; the sealing ring 1115 forms a closed liquid passage between the mixing portion 11 and the cylinder body 13;

[0066] As the mixing portion 11 reciprocates relative to the cylinder body 13 , the sealing ring 1115 opens and closes the opening 1114 , so that the liquid in the liquid storage tank 3 is sucked into the liquid containing cavity, and the liquid in the liquid containing cavity is pressed into the mixing portion 11 through the opening 1114 .

[0067] 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 pressed (sucked) into the liquid chamber and then discharged from the opening 1114. The principle of absorbing water is similar to that of pressing the pump head.

[0068] like Figure 6 As shown, 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 body 13 includes a water pipe 132 and a liquid pipe 131 for holding water, and 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; so that the water inlet end 1112 and the liquid inlet end 1113 respectively extend into the water pipe 132 and the liquid pipe 131; the connecting pipe 14 includes a water suction pipe 141 and a liquid suction pipe 142, and the water suction pipe 141 and the liquid suction pipe 142 correspond to the water pipe 132 and the liquid pipe 131 respectively, so that the water suction pipe 141 and the liquid suction pipe 142 respectively extend into the clean water space and the hand soap space in the liquid storage tank 3. Since the structures on the water pipe 132 and the liquid pipe 131 are similar, the following only describes the relationship between the water pipe 132 and the water inlet end 1112.

[0069] An opening 1114 is formed on the side wall of the water inlet end 1112. A sealing ring 1115 is sleeved on the side wall of the water inlet end 1112. The sealing ring 1115 slides relative to the water inlet end 1112 to cover the opening 1114, thereby restricting the flow of clean water from the water inlet end 1112 into the mixing section 11. At the same time, the sealing ring 1115 is squeezed against the inner wall of the water pipe 132, thereby forming a liquid-containing cavity in the water pipe 132.

[0070] Furthermore, the mixing section 11 reciprocates up and down, and the up and down movement of the mixing section 11 is one cycle. When the mixing section 11 moves upward, the sealing ring 1115 is located in a position blocking the opening 1114. At this time, the volume of the liquid storage chamber is stretched and increased, and the air pressure inside the liquid storage chamber 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 clean water in the liquid storage tank 3 is sucked into the liquid storage chamber; and when the mixing section 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 liquid storage chamber is compressed, and the pressure inside the liquid storage chamber is increased, so that the one-way valve 134 is pressed tightly against the water pipe 132, limiting the backflow of clean water. Under the influence of pressure, the clean water in the liquid storage chamber is pressed into the opening 1114, thereby completing the process of clean water passing from the liquid storage tank 3 into the mixing section 11.

[0071] like Figure 4 、11 As shown, in a preferred embodiment, the water pipe 132 is detachably connected to the main body of the cylinder body 13; an adjusting portion 133 for adjusting the length of the water pipe 132 is provided on the cylinder body 13; the water pipe 132 is adjusted by the adjusting portion 133 so that the extended end of the water pipe 132 extends to near the bottom of the liquid storage tank 3, making it convenient to fully absorb the clean water in the liquid storage tank 3.

[0072] Specifically, the adjustment portion 133 includes an adjustment groove provided on the cylinder body 13, which is a transverse groove at different heights. The transverse groove cooperates with the protrusion on the outer wall of the water pipe 132, so that the cylinder body 13 and the water pipe 132 are connected in a coordinated manner. By fitting the protrusion in the transverse groove at different heights, the position of the water pipe 132 is adjusted.

[0073] like Figure 12 、 13 As shown, it should be pointed out that a spring is provided between the one-way valve 134 in the liquid pipe 131 and the liquid inlet end 1113. Since the hand soap is too viscous, the one-way valve in the liquid pipe 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.

[0074] like Figure 8 、 9 As shown, the foaming portion 12 includes a primary foaming frame 121, which is adhered to the mixing portion 11 via a sealing film 113; the primary foaming frame 121 and the cylinder body 13 form an air pressure chamber 1211, and by compressing the air pressure chamber 1211, the gas passes through the sealing film 113 and enters the mixed liquid outlet 1123 of the mixing portion 11, and contacts the mixed liquid to form foam.

[0075] like Figure 10 As shown, specifically, 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.

[0076] like Figure 5 、 14As shown, the mixing section 11 includes a mixing chamber 111 and a mixing cover 112. The mixing cover 112 is connected to the first-level foaming frame 121 and is provided with a receiving portion 1121 at one end. The receiving portion 1121 is provided with a mixed liquid outlet 1123 for discharging the mixed liquid, 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 1211 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, 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] The foaming section 12 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.

[0079] like Figure 8-10 As shown, 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 1211 is compressed, so that the pressure in the air pressure chamber 1211 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 1211 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.

[0080] 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 air pressure in the air pressure chamber 1211. 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 1211, preparing for the next downward movement of the first-level foaming frame 121.

[0081] The foaming portion 12 is driven by a driving module 123 , causing the foaming portion 12 to reciprocate, thereby pressing the gas into the foaming portion 12 ;

[0082] The foaming part 12 is connected to 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. The mixing part 11 presses the mixing liquid into the foaming part 12 through reciprocating motion, thereby completing the foaming operation. A driving module 123 is used to simultaneously drive the foaming part 12 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.

[0083] 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.

[0084] like Figure 4 、 8 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 foaming part 12, so that the driving module 123 drives the foaming part 12 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 124 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 124 includes a crank 1232 and a rocker 1233. The crank 1232 and the rocker 1233 in the balancing module 124 rotate as the first-level foaming frame 121 moves up and down, and its movement trajectory is consistent with the driving module 123. By setting the balancing module 124, 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] like Figure 12-14 As shown, the working process of the foaming device mainly includes: when the device is working, the drive motor 1231 rotates to cause the primary foaming frame 121 to drive the mixing part 11 and others to move up and down. When the primary foaming frame 121 moves downward, the mixing part 11 also moves downward. Under the action of friction, the sealing ring 1115 is stuck above the water inlet end 1112 and the liquid inlet end 1113 of the mixing part 11. The opening 1114 allows the water and hand soap in the outer water inlet pipe 132 and the liquid pipe 131 to enter. At this time, the one-way valves in the outer water pipe 132 and the liquid pipe 131 are pressed tightly against the bottom of the pipe due to the pressure, preventing the water and hand soap from flowing downward. Because of the air pressure in the air pressure chamber 1211, the gas pushes up the one-way air inlet membrane 125 so that the gas will not overflow through the air inlet 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 push open the elastic sealing membrane 113 through the gap above the mixing cover 112, mix with the mixed liquid and then enter the first-level foaming frame 121. 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. Under the action of friction, the sealing ring 1115 is stuck below the water inlet end 1112 and the liquid inlet end 1113 on the mixing part 11, closing the opening 1114 for the water and hand soap in the outer water pipe 132 and the liquid pipe 131 to enter. At this time, the one-way valve 134 in the outer water pipe 132 and the liquid pipe 131 generates negative pressure due to the upward movement of the inner pipe, and is lifted from the bottom of the pipe. The spring in the liquid pipe is also overcome by the spring force, so that the water and hand soap are sucked out from the container below. Because of the negative pressure in the air pressure chamber 1211, the gas sucks the elastic sealing membrane 113 on the gap above the mixing cover 112, so that the gas cannot enter through the one-way air intake membrane 125. The surrounding outer walls are still sealed because the first-level foaming frame 121 and the inner wall of the cylinder body 13 are sealed, so the gas can only suck down the one-way air intake membrane 125 through the negative pressure. Even if the one-way air intake membrane 125 moves downward, the air intake hole 1215 is exposed, allowing the gas to enter the air pressure chamber 1211, preparing for the next downward movement of the first-level foaming frame 121.

[0089] The present invention provides a water-liquid self-mixing foaming device. Water and liquid enter a mixing section separately to form a mixed liquid in the mixing section, and then enter a foaming section for foaming, thereby facilitating self-mixing hand soap and foaming operations, and having strong applicability. A driving module simultaneously drives a primary foaming frame to drive the mixing section, thereby simultaneously performing water-liquid mixing and foaming, simplifying the foaming process. An air intake grid is provided on the inner wall of the primary foaming frame to ensure more complete gas-liquid mixing. Air intake holes are provided around the primary foaming frame, which cooperate with a one-way air intake membrane to prevent gas from overflowing when the primary foaming frame moves downward and to allow gas to be inhaled when the primary foaming frame moves upward. A closed curve provided on the outer side of the primary foaming frame cooperates with the inner wall of a cylinder to limit gas overflow. By replacing an adjustable connecting pipe, the diameter of the connecting pipe is expanded or reduced, the amount of water and / or liquid inlet is adjusted, thereby adjusting the water-liquid mixing concentration ratio. By replacing a crank and a connecting rod, the amount of water-liquid-gas mixture obtained per motor rotation is adjusted, thereby adjusting the volume that can be pumped out per unit time. The present invention has a simple structure and is easy to use.
