Description

Technical Field

[0001] This invention relates to a pressing component. Background Technology

[0002] Existing push-button components have many parts and complex structures during production. The assembly process is lengthy, resulting in low worker efficiency and high production costs. Furthermore, the components are made from a variety of materials. Therefore, recycling these components after use requires disassembly and recycling them according to the materials, which is cumbersome and environmentally unfriendly.

[0003] In addition, many existing push-button components use metal elastic elements to provide a reset function. However, after prolonged use, metal elastic elements are prone to fatigue and loss of elasticity, making them unable to reset and function. At the same time, metal elastic elements are also prone to corrosion and oxidation, resulting in rust spots that can contaminate the contents of the container.

[0004] This invention was developed based on the aforementioned shortcomings. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pressing assembly with a compact and simple structure, few parts, and easy assembly. Moreover, the pressing assembly of this invention adopts an air spring structure, which also has the advantages of good rebound effect and will not contaminate the contents of the container. It avoids the defects of using traditional metal, plastic or soft rubber springs, which lead to complex assembly structure, high manufacturing cost, easy fatigue damage and pollution. Therefore, the structure of this invention can be made into a pressing assembly that is easy to recycle and more environmentally friendly.

[0006] This invention is achieved through the following technical solution:

[0007] A pressing assembly includes a base 1 connected to the opening of a container. A pressing dispensing assembly 2, which can dispensing liquid outward when sliding relative to the base 1, is connected to the base 1. The pressing dispensing assembly 2 includes a pressing member 21 connected to the base 1. A connecting member 22, which can move relative to the pressing member 21, is connected to the pressing member 21. A first receiving cavity 300 for receiving the dispensing substance is formed between the connecting member 22, the pressing member 21, and the base 1. The pressing member 21 is provided with a dispensing port 211 that communicates with the first receiving cavity 300 and is used for dispensing liquid. An opening and closing assembly 6 is provided between the pressing member 21 and the connecting member 22, which opens when the pressing member 21 slides relative to the connecting member 22 to communicate with the dispensing port 211 and the first receiving cavity 300.

[0010] The reset member 5 includes a closed cavity 51 provided on the pressing member 21. The base 1 is provided with a pressing part 52 that can move within the closed cavity 51 to change the volume of the closed cavity 51. The increase or decrease in the volume of the closed cavity 51 causes a pressure difference between the closed cavity 51 and the external atmosphere, which allows the pressing part 52 to slide and reset when the external force is removed.

[0011] The sealing part 62 is a sealing plate connected to the pipe body 221.

[0012] The sealing part 62 is an extension tube connected to the tube body 221. The extension tube is provided with a second receiving cavity 620 that can connect the first receiving cavity 300 and the liquid outlet 211. The sealing part 62 is also provided with a wall hole 621 that can be aligned with the connecting hole 61 when the pressing member 21 slides relative to the connecting member 22, thereby connecting the second receiving cavity 620 with the first receiving cavity 300. When the pressing member 21 slides in the opposite direction relative to the connecting member 22, the connecting hole 61 is fitted with the wall surface of the extension tube and closed.

[0013] An air inlet chamber 700 is formed between the pressing member 21 and the base 1. The connecting member 22 and the pressing member 21 cooperate to form an air pumping chamber 800 that can pump air into the second receiving chamber 620. The pressing member 21 is provided with a vent hole 213 that can connect the air inlet chamber 700 and the air pumping chamber 800. The sealing part 62 is also provided with an air inlet hole 622 that can connect the second receiving chamber 620 and the air pumping chamber 800 when the pressing member 21 slides relative to the connecting member 22. When the pressing member 21 slides in the opposite direction relative to the connecting member 22, the air inlet hole 622 is fitted with the wall surface of the pressing member 21 and closed.

[0014] The pressing component 21 is provided with a one-way air intake valve 214 that can connect the air intake chamber 700 and the outside atmosphere.

[0015] The pressing member 21 is provided with a flow channel 400 that connects the liquid outlet 211 and the second receiving cavity 620, and the pressing member 21 is also provided with an air supply hole 215 that connects the flow channel 400 and the air inlet cavity 700. The tube body 221 is also connected with a connecting tube 23 that can close or open the air supply hole 215 when the pressing member 21 slides relative to the base 1.

[0016] The connecting pipe 23 is provided with a transition channel 230 that can connect the flow channel 400 and the second receiving cavity 620. The lower end of the connecting pipe 23 is connected to a stop part 231. The connecting pipe 23 is provided with a transition connection hole 232 that can connect the transition channel 230 and the second receiving cavity 620.

[0017] A pressing assembly includes a base 91 connected to the opening of a container. A connector 92, which can drain liquid outward when sliding relative to the base 91, is connected to the base 91. A pressing member 94, which can move relative to the base 91 and press against the connector 92, slides. The connector 92 includes a first connecting cylinder 921 slidably disposed on the base 91. A second connecting cylinder 922, which can slide relative to the first connecting cylinder 921, is connected to the first connecting cylinder 921. The second connecting cylinder 922, the pressing member 94, and the base 91 cooperate to form a first receiving cavity 930 for storing the discharged substance. The pressing member 94 is provided with a liquid outlet 941 communicating with the first receiving cavity 930 and used for discharging liquid. A reset member 95, which can drive the connector 92 to reset, is also provided between the connector 92 and the base 91.

[0018] The second connecting cylinder 922 is provided with a second receiving cavity 9220, and an infusion channel 960 is provided between the second connecting cylinder 922 and the pressing member 94, which can connect the second receiving cavity 9220 and the first receiving cavity 930. The pressing member 94 is provided with a first sealing part 942 that can close or open the infusion channel 960 when it slides relative to the base 91.

[0019] The pressing member 94 and the base 1 cooperate to form a transport channel 970 that can inflate the inside of the container when the pressing member 94 slides relative to the base 1 and suck out the contents of the container when the pressing member 94 moves upward.

[0020] The pressing member 94 is provided with a second sealing part 943 and a third sealing part 944. When the pressing member 94 slides relative to the base 1, the second sealing part 943 fits against the wall of the base 1 to separate the transport channel 970 from the first receiving cavity 930. When the pressing member 94 slides in the opposite direction relative to the base 1, the second sealing part 943 disengages from the wall of the base 1 to connect the transport channel 970 with the first receiving cavity 930.

[0021] When the pressing member 94 slides relative to the base 91, the third sealing part 944 disengages from the wall of the base 91, thus connecting the transport channel 970 with the interior of the container. When the pressing member 94 slides in the opposite direction relative to the base 91, the third sealing part 944 adheres to the wall of the base 91, thus separating the transport channel 970 from the interior of the container.

[0022] The reset component 95 includes a closed cavity 951 disposed on the base 91. The first connecting cylinder 921 is provided with a pressing part 952 that can move within the closed cavity 951 to change the volume of the closed cavity 951. The increase or decrease in the volume of the closed cavity 951 causes a pressure difference between the closed cavity 951 and the external atmosphere, which allows the pressing part 952 to slide and reset when the external force is removed.

[0023] The pressing member 94 is also provided with a connecting cavity 940 that connects to the liquid outlet 941 and the second receiving cavity 9220. A cavity 980 is formed between the first connecting cylinder 921 and the base 1. The first connecting cylinder 921 is provided with a one-way air inlet valve 9211 that connects the cavity 980 and the connecting cavity 940. A valve is also provided between the first connecting cylinder 921 and the second connecting cylinder 922 that allows air in the cavity 980 to be pumped into the second connecting cylinder 922 when the first connecting cylinder 921 moves relative to the second connecting cylinder 922. The air chamber 990 is located within the receiving cavity 9220. The first connecting cylinder 921 is provided with a first air hole 9212 that can connect the air chamber 990 and the cavity 980 when it slides relative to the second connecting cylinder 922. When the first connecting cylinder 921 slides in the opposite direction relative to the second connecting cylinder 922, the first air hole 9212 is fitted and sealed against the wall of the second connecting cylinder 922. The second connecting cylinder 922 is also provided with a second air hole 9221 that can connect the air chamber 990 and the receiving cavity 9220.

[0024] A reset assembly 99 is also provided between the pressing member 94 and the base 91.

[0025] Compared with the prior art, the present invention has the following advantages: When using the pressing assembly of the present invention, firstly, the pressing member is operated, moving downwards and pressing against the connecting member. At this time, the connecting member and the pressing member cooperate to discharge the air in the first receiving cavity through the liquid outlet. When the pressing member and the connecting member move upwards to reset, the air pressure in the first receiving cavity is lower than that in the container, allowing the substance in the container to be drawn out into the first receiving cavity for storage. Then, the pressing member is operated again, and the connecting member pumps the substance in the first receiving cavity out through the liquid outlet and replenishes the air in the first receiving cavity, continuously... Operating the pressing component allows for continuous pumping of substances from the container, making it very convenient to use. When the external force on the pressing component is removed, the reset component pushes the pressing component and connecting component to spring back to their original position. The reset method is simple, and all parts of the pressing assembly can be made of the same material, which facilitates processing and reduces production costs. Due to the uniformity of the processing materials, the pressing assembly is also easier to recycle and more environmentally friendly. Compared with existing pressing assemblies, this pressing assembly has a more compact structure and uses fewer parts, making it easier for workers to assemble. Attached Figure Description

[0044] The present invention will now be further described with reference to the accompanying drawings:

[0045] Example 1:

[0046] like Figures 1 to 2 As shown, the present invention provides a pressing assembly, including a base 1 connected to the opening of a container. A pressing liquid dispensing assembly 2 is connected to the base 1 and can dispense liquid outward when sliding relative to it. The pressing liquid dispensing assembly 2 includes a pressing member 21 connected to the base 1. A connecting member 22 that can move relative to the pressing member 21 is connected to the pressing member 21. The connecting member 22, the pressing member 21 and the base 1 form a first receiving cavity 300 for receiving the discharged substance. The pressing member 21 is provided with a liquid outlet 211 that communicates with the first receiving cavity 300 and is used for dispensing liquid. An opening and closing assembly 6 is provided between the pressing member 21 and the connecting member 22, which opens when the pressing member 21 slides relative to the connecting member 22 to communicate the liquid outlet 211 with the first receiving cavity 300. A reset member 5 that can drive the connecting member 22 to reset is also provided between the pressing member 21 and the base 1.

[0047] In use, the pressing assembly of this invention first operates the pressing member 21, which moves downward and presses against the connecting member 22. At this time, the connecting member 22 and the pressing member 21 cooperate to discharge the air in the first receiving cavity 300 through the liquid outlet 211. When the pressing member 21 and the connecting member 22 move upward and reset, the air pressure in the first receiving cavity 300 is lower than that in the container, which allows the substance in the container to be drawn out into the first receiving cavity 300 for storage. Simultaneously, the air in the first receiving cavity 300 is discharged again. By operating the pressing member 21 again, the connecting member 22 pumps the substance in the first receiving cavity 300 out through the liquid outlet 211. By replenishing the container with air and continuously operating the pressing component 21, the contents of the container can be continuously pumped out, making it very convenient to use. When the external force on the pressing component 21 is removed, the reset component 5 pushes the pressing component 21 and the connecting component 22 to spring back and reset. The reset method is simple, and all parts of the pressing assembly can be made of the same material, which is convenient for processing and production and reduces production costs. Due to the uniformity of the processing materials, the pressing assembly is also more convenient and environmentally friendly to recycle. Compared with the existing pressing assembly, the structure of this pressing assembly is more compact and uses fewer parts, making it easier for workers to assemble.

[0048] like Figures 1 to 2 As shown, the opening / closing assembly 6 includes a connecting hole 61 on the pressing member 21 for connecting the first receiving cavity 300 and the liquid outlet 211, and a sealing part 62 on the connecting member 22 that can close or open the connecting hole 61 when the pressing member 21 slides relative to the connecting member 22. The sealing part 62 and the connecting hole 61 cooperate to close the first receiving cavity 300 and the liquid outlet 211, preventing external dust or particles from entering the first receiving cavity 300 and contaminating the substances inside the first receiving cavity 300. The sealing part 62 is a sealing plate connected to the tube body 221. The opening / closing assembly 6 can replace the closing valve, reducing the number of parts used. Moreover, the connecting hole 61 and the sealing part 62 are common components that can be processed during the molding of the pressing member 21 and the connecting member 22 without additional processing, reducing production costs, reducing material waste, and being more environmentally friendly.

[0049] like Figures 1 to 2As shown, the connector 22 includes a tube 221. The tube 221 has a transport channel 222 that pumps air into the container when sliding downwards and draws out the contents of the container when the connector 22 moves upwards. The connector 22 also has a drain hole 223 that connects the first receiving cavity 300 and the transport channel 222. The pressing member 21 has a sealing part 216 that closes the drain hole 223 when sliding relative to the connector 22. When the connector 22 slides downwards relative to the pressing member 21, the transport channel 222 extends into the container, allowing the contents to flow quickly into the first receiving cavity 300. Since some contents remain in the first receiving cavity 300 after being discharged to the outlet 211, a gentle press of the pressing member 21 allows for easy dispensing. The pressing member 21 has a flow channel 400.

[0050] like Figures 1 to 2 As shown, the reset component 5 includes a closed cavity 51 disposed on the pressing component 21. The base 1 has a pressing part 52 that can move within the closed cavity 51 to change its volume. The increase or decrease in the volume of the closed cavity 51 creates a pressure difference between the closed cavity 51 and the external atmosphere, which allows the pressing part 52 to slide back to its original position when the external force is removed. Because the reset component 5 uses compressed air rebound, fatigue of the metal spring can be avoided, and rust will not appear, thus preventing contamination of the contents of the container.

[0051] Working principle:

[0052] When the pressing device is in use, the pressing member 21 is first pressed down. When the pressing member 21 is pressed down, the sealing part 62 on the connecting member 22 disengages from the communicating hole 61 on the pressing member 21, thereby allowing the first receiving cavity 300 and the liquid outlet 211 to communicate with each other through the communicating hole 61. The sealing part 216 on the pressing member 21 seals the drain hole 223 of the connecting member 22. When the pressing member 21 continues to move down, it presses against the connecting member 22. At this time, the pressing member 21 and the connecting member 22 move downward, and the air in the first receiving cavity 300 is ejected from the communicating hole 61 and then from the liquid outlet 211. At this time, the volume of the first receiving cavity 300 decreases.

[0053] After the pressure of the pressing member 21 is released, the pressing member 21 is reset by the reset member 5 and moves upward. The upward movement of the pressing member 21 causes the connecting hole 61 to abut against the sealing part 62. At this time, the first receiving cavity 300 is isolated from the external air and connected to the internal pipe of the container. As the volume of the first receiving cavity 300 gradually increases and the air pressure in the first receiving cavity 300 is less than the air pressure in the container, the substance in the container can be squeezed out of the drain hole 223 by the air pressure in the container through the transport channel 222 and stored in the first receiving cavity 300. This causes the pressing member 21 to drive the connecting member 22 to reset. At this time, the connecting hole 61 is closed by the sealing part 62, and the first receiving cavity 300 and the outlet 211 cannot communicate.

[0054] When the pressing member 21 is pressed down again, the sealing part 62 separates from the connecting hole 61, connecting the first receiving cavity 300 and the liquid outlet 211 through the connecting hole 61. Air is replenished to the first receiving cavity 300, and before the sealing part 216 completely seals the drain hole 223, air is replenished to the container through the transport channel 222. The pressing member 21 continues to move downwards, and the sealing part 216 on the pressing member 21 seals the drain hole 223 again. The pressing member 21 squeezes the substance stored in the first receiving cavity 300, causing the substance to pass through the connecting hole 61 and be pumped out from the liquid outlet 211. Simultaneously, as the pressing member 21 and the connecting member 22 move downwards, they work together to expel the air from the first receiving cavity 300 to the outside. Of course, this pressing assembly can also be used to spray solutions or liquids such as water, and can pump out more uniform water mist, water droplets, water particles, water lines, etc., by mixing with air. It can also be used to pump powders or granules.

[0055] Example 2:

[0056] like Figures 3 to 4 As shown, the difference between this embodiment and embodiment 1 is that the sealing part 62 is an extension tube connected to the tube body 221. The extension tube is provided with a second receiving cavity 620 that can connect the first receiving cavity 300 and the liquid outlet 211. The sealing part 62 is also provided with a wall hole 621 that can be aligned with the connecting hole 61 when the pressing member 21 slides relative to the connecting member 22, thereby connecting the second receiving cavity 620 with the first receiving cavity 300. When the pressing member 21 slides in the opposite direction relative to the connecting member 22, the connecting hole 61 is fitted with the wall surface of the extension tube and closed.

[0057] Only when the connector 22 slides relative to the pressing member 21 until the wall hole 621 is aligned with the connecting hole 61, the second receiving cavity 620 can communicate with the first receiving cavity 300. When the pressing member 21 is pressed down again, the substance in the first receiving cavity 300 enters the second receiving cavity 620 through the connecting hole 61 and the wall hole 621, and is then pumped out from the liquid outlet 211.

[0058] Example 3:

[0059] like Figures 5 to 10 As shown, the difference between this embodiment and embodiment 2 is that an air inlet chamber 700 is formed between the pressing member 21 and the base 1, and an air pumping chamber 800 is formed between the connecting member 22 and the pressing member 21 to pump air into the second receiving chamber 620. The pressing member 21 is provided with a vent hole 213 that can connect the air inlet chamber 700 and the air pumping chamber 800. The sealing part 62 is also provided with an air inlet hole 622 that can connect the second receiving chamber 620 and the air pumping chamber 800 when the pressing member 21 slides relative to the connecting member 22. When the pressing member 21 slides in the opposite direction relative to the connecting member 22, the air inlet hole 622 is fitted with the wall surface of the pressing member 21 and closed.

[0060] The pressing member 21 is provided with a one-way air intake valve 214 that connects the air intake chamber 700 to the outside atmosphere. When the pressing member 21 slides upward, the one-way air intake valve 214 opens to replenish the air intake chamber 700 with air.

[0061] Working principle:

[0062] When the pressing device is in use, the pressing member 21 is first pressed down. When the pressing member 21 is pressed down, the sealing part 62 on the connecting member 22 disengages from the communicating hole 61 on the pressing member 21, thereby allowing the first receiving cavity 300, the second receiving cavity 620 and the liquid outlet 211 to communicate with each other through the communicating hole 61. The sealing part 216 on the pressing member 21 seals the drain hole 223 of the connecting member 22. When the pressing member 21 continues to move down, it presses against the connecting member 22, and the air inlet 622 in the sealing part 62 separates from the wall of the pressing member 21. The air inlet cavity 700, the air pumping cavity 800 and the second receiving cavity 620 are connected. When the pressing member 21 moves downward, the air in the air inlet chamber 700 enters the air pumping chamber 800 through the vent 213. As the pressing member 21 continues to move downward, the vent 213 is sealed by the wall of the base 1, and the air pumping chamber 800 becomes a sealed chamber. The compressed air in the air pumping chamber 800 is pumped into the second receiving chamber 620 through the air inlet 622. As the pressing member 21 and the connecting member 22 continue to move downward, the gas in the first receiving chamber 300 can enter the second receiving chamber 620 through the connecting hole 61 and the wall hole 621 and then be discharged outward from the liquid outlet. At this time, the volume of the first receiving chamber 300 decreases.

[0063] After the pressure of the pressing member 21 is released, the pressing member 21 is reset by the reset member 5 and moves upward. When the pressing member 21 moves upward, it drives the connecting member 22 to reset, and the connecting hole 61 is sealed by the sealing part 62. At this time, the first receiving cavity 300 is isolated from the external air and connected to the inside of the container. Since the volume of the first receiving cavity 300 gradually increases, and the air pressure in the first receiving cavity 300 is less than the air pressure in the container, the substance in the container can be squeezed into the first receiving cavity 300 by the pressure in the container through the conveying channel 222 and the drain hole 223.

[0064] When the pressing member 21 is pressed down again, the sealing part 62 separates from the connecting hole 61, connecting the first receiving cavity 300, the second receiving cavity 620, and the liquid outlet 211 through the connecting hole 61. Air is replenished to the first receiving cavity 300, and air is replenished to the container through the transport channel 222 before the sealing part 216 completely seals the drain hole 223. The pressing member 21 continues to move downwards, and the sealing part 216 on the pressing member 21 seals the drain hole 223 again. Simultaneously, the pressing member 21 compresses the substance stored in the first receiving cavity 300. When the wall hole 621 is aligned with the connecting hole 61, the substance in the first receiving cavity 300 enters the second receiving cavity 620 through the connecting hole 61 and the wall hole 621, and is then pumped out from the liquid outlet 211. The air in the air inlet cavity 700 is pumped into the air pumping cavity 800 and enters the second receiving cavity 620 through the air inlet hole 622. After mixing with the substance to generate foam, it is pumped out from the liquid outlet 211. When the pressing member 21 squeezes the substance stored in the first receiving cavity 300, the air in the first receiving cavity 300 is pumped out again.

[0065] Example 4:

[0066] like Figures 11 to 12 As shown, the difference between this embodiment and Embodiment 3 is that the pressing member 21 is provided with a flow channel 400 that connects the liquid outlet 211 and the second receiving cavity 620, and the pressing member 21 is also provided with an air supply hole 215 that connects the flow channel 400 and the air inlet cavity 700. The tube body 221 is also connected to a connecting tube 23 that can close or open the air supply hole 215 when the pressing member 21 slides relative to the base 1. When the pressing member 21 moves downward, the air supply hole 215 contacts the tube wall of the connecting tube 23 and closes the air supply hole 215. At this time, the air inlet cavity 700 is a sealed cavity, and air cannot enter the air inlet cavity 700 through the air supply hole 215. As a result, the air in the air inlet cavity 700 is compressed and becomes compressed air when the pressing member 21 moves downward. Furthermore, when the pressing member 21 moves upward, the air outlet 215 disengages from the wall of the connecting pipe 23. At this time, external air can enter the air inlet chamber 700 from the liquid outlet 211 through the air outlet 215 to replenish the air in the cavity.

[0067] The connecting pipe 23 is provided with a transition channel 230 that connects the flow channel 400 and the second receiving cavity 620. The lower end of the connecting pipe 23 is connected to a stop part 231, and the connecting pipe 23 is provided with a transition connection hole 232 that connects the transition channel 230 and the second receiving cavity 620. The stop part 231 is a baffle or a cross-shaped block. When the substance is squeezed by the compressed air in the air chamber 800, it crawls along the wall of the stop part 231 to the transition connection hole 232, and is then pumped out through the flow channel 400 and the liquid outlet 211. The substance mixes more thoroughly with the air when crawling on the wall of the stop part 231 and passing through the transition connection hole 232, resulting in finer foam.

[0068] Example 5:

[0069] like Figures 13 to 18 As shown, the difference between this embodiment and embodiment 3 lies in a pressing assembly, including a base 91 connected to the container opening. A connector 92 is connected to the base 91 and can drain liquid outward when sliding relative to it. The base 91 is also provided with a pressing member 94 that can move relative to it and press against the connector 92 to slide. The connector 92 includes a first connecting cylinder 921 slidably disposed on the base 91. A second connecting cylinder 922 that can slide relative to the first connecting cylinder 921 is also connected to the first connecting cylinder 921. The second connecting cylinder 922, the pressing member 94 and the base 1 cooperate to form a first receiving cavity 930 that can store the discharged substance. The pressing member 94 is provided with a liquid outlet 941 that communicates with the first receiving cavity 930 and is used for liquid discharge. A reset member 95 that can drive the connector 92 to reset is also provided between the connector 92 and the base 91.

[0070] When using the pressing assembly, firstly, operate the pressing member 94. The pressing member 94 moves downward and presses against the first connecting cylinder 921 and the second connecting cylinder 922. At this time, the air in the first receiving cavity 930 is discharged outward through the liquid outlet 941. When the connecting cylinders 921 and the second connecting cylinder 922 reset, the first receiving cavity 930 is under negative pressure, which can draw the substance in the container into the first receiving cavity 930 for storage. Then, operate the pressing member 94 again, and the connecting member 92 pumps the substance in the first receiving cavity 930 outward through the liquid outlet 941. Continue to operate the pressing member 94. It can continuously pump the contents of the container outward, which is very convenient to use. When the external force on the pressing component 21 is removed, the reset component 5 pushes the first connecting cylinder 921 and the second connecting cylinder 922 to spring back and reset. The reset method is simple, and all parts of the pressing component can be made of the same material, which is convenient for processing and production and reduces the production cost. Due to the uniformity of the processing materials, the pressing component is also more convenient and more environmentally friendly to recycle. Compared with the existing pressing components, the structure of this pressing component is more compact and uses fewer parts, which makes it easier for workers to assemble.

[0071] like Figures 13 to 18 As shown, the second connecting cylinder 922 is provided with a second receiving cavity 9220, and an infusion channel 960 connecting the second connecting cylinder 922 and the pressing member 94 is provided, which can connect the second receiving cavity 9220 and the first receiving cavity 930. The pressing member 94 is provided with a first sealing part 942 that can close or open the infusion channel 960 when it slides relative to the base 91. The first sealing part 942 is used to close the infusion channel 960 to prevent liquid backflow. Moreover, the first sealing part 942 is a sealing ring, which can be processed simultaneously during production, saving production costs.

[0072] like Figure 13 and Figure 18 As shown, the pressing member 94 and the base 1 cooperate to form a transport channel 970 that can inflate the inside of the container when the pressing member 94 slides relative to the base 1 and suck out the contents of the container when the pressing member 94 moves upward. When the second connecting cylinder 922 moves upward, the contents of the container are discharged outward into the first receiving cavity 930. Then, the pressing member 94 is operated again, and the pressing member 94 pushes the first connecting cylinder 921 downward. At this time, the contents in the first receiving cavity 930 are squeezed and enter the second receiving cavity 9220 through the infusion channel 960.

[0073] like Figure 13 , 14 As shown in Figure 17, the pressing member 94 is provided with a second sealing part 943 and a third sealing part 944. When the pressing member 94 slides relative to the base 1, the second sealing part 943 adheres to the wall surface of the base 1, thus separating the transport channel 970 from the first receiving cavity 930. When the pressing member 94 slides in the opposite direction relative to the base 1, the second sealing part 943 disengages from the wall surface of the base 1, thus connecting the transport channel 970 with the first receiving cavity 930. When the transport channel 970 is separated from the first receiving cavity 930, the gas in the transport channel 970 can be forced into the container.

[0074] When the pressing member 94 slides relative to the base 91, the third sealing part 944 disengages from the wall of the base 91, connecting the transport channel 970 with the interior of the container. When the pressing member 94 slides in the opposite direction relative to the base 91, the third sealing part 944 adheres to the wall of the base 91, separating the transport channel 970 from the interior of the container. When the transport channel 970 connects with the first receiving cavity 930, the third sealing part 944 can seal the container and the first receiving cavity 930, preventing liquid in the first receiving cavity 930 from flowing back into the container.

[0075] like Figures 13 to 14As shown, the reset component 95 includes a closed cavity 951 disposed on the base 91. The first connecting cylinder 921 contains a pressing part 952 that can move within the closed cavity 951 to change its volume. The increase or decrease in the volume of the closed cavity 951 creates a pressure difference between the closed cavity 951 and the external atmosphere, allowing the pressing part 952 to slide back to its original position when the external force is removed. Because the reset component 95 uses compressed air rebound, fatigue of the metal spring can be avoided, and rust will not appear, thus preventing contamination of the contents of the container.

[0076] like Figures 13 to 14 As shown, the pressing member 94 is also provided with a connecting cavity 940 that can connect the liquid outlet 941 and the second receiving cavity 9220. A cavity 980 is formed between the first connecting cylinder 921 and the base 1. The first connecting cylinder 921 is provided with a one-way air inlet valve 9211 that can connect the cavity 980 and the connecting cavity 940. A valve is also provided between the first connecting cylinder 921 and the second connecting cylinder 922, which can pump air from the cavity 980 into the second connecting cylinder 940 when the first connecting cylinder 921 moves relative to the second connecting cylinder 922. The first connecting cylinder 921 is provided with a first air-injection chamber 990 in the second receiving cavity 9220. When the first connecting cylinder 921 slides relative to the second connecting cylinder 922, it can connect the air-injection chamber 990 and the cavity 980. When the first connecting cylinder 921 slides in the opposite direction relative to the second connecting cylinder 922, the first air-injection hole 9212 is fitted and closed with the wall of the second connecting cylinder 922. The second connecting cylinder 922 is also provided with a second air-injection hole 9221 that can connect the air-injection chamber 990 and the second receiving cavity 9220.

[0077] like Figures 13 to 14 As shown, a reset assembly 99 is also provided between the pressing member 94 and the base 91. The reset assembly 99 is an air spring, the same as the reset member 95 described above.

[0078] Working principle:

[0079] When the pressing assembly is in use, pressing down on the pressing member 94 causes the first connecting cylinder 921 to move downwards. During this movement, the first sealing part 942 on the pressing member 94 disengages from the side wall of the second connecting cylinder 922, thereby allowing the second receiving cavity 9220 and the first receiving cavity 930 to communicate with each other through the transport channel 970. The second sealing part 943 on the pressing member 94 adheres to the wall of the base 91, separating the transport channel 970 from the first receiving cavity 930. As the pressing member 94 continues to move downwards, the second connecting cylinder 922 presses against the second connecting cylinder 922, and at the same time, the pressing member 94 simultaneously presses against the second connecting cylinder 922. The second connecting cylinder 922 and the first connecting cylinder 921 move downwards, causing the air in the first receiving cavity 930 to be discharged outwards through the delivery channel 970 and the second receiving cavity 9220 via the outlet 941. At this time, the volume of the first receiving cavity 300 decreases, and when the first connecting cylinder 921 moves downwards relative to the second connecting cylinder 922, the first air-pressing hole 9212 on the first connecting cylinder 921 separates from the wall of the second connecting cylinder 922, connecting the air-pressing cavity 990 and the cavity 980. The air in the cavity 980 can be forced into the second receiving cavity 9220 through the second air-pressing hole 9221.

[0080] After the pressure of the pressing member 94 is released, the first connecting cylinder 921 moves upward by resetting via the resetting member 95, and the pressing member 94 is reset upward by the resetting assembly 99. At this time, the first sealing part 942 inside the pressing member 94 and the wall surface of the second connecting cylinder 922 fit together, blocking the first receiving cavity 930 from the transport channel 970. At this time, the first receiving cavity 930 is isolated from the outside air but communicates with the inside of the container through the transport channel 970. As the volume of the first receiving cavity 930 gradually increases and the air pressure inside the first receiving cavity 930 is lower than the air pressure inside the container, the second sealing part 943 disengages from the wall surface of the base 91 when the first connecting cylinder 921 moves upward, and the third sealing part 944 closes the transport channel. Before the container is separated from the interior, the material inside the container is squeezed from the transport channel 970 into the first receiving cavity 930 by the pressure inside the container. The first connecting cylinder 921 continues to move upward until the third sealing part 944 is attached to the wall of the base 91, thus separating the transport channel 970 from the interior of the container. The first receiving cavity 930 and the infusion channel 960 cannot be connected. When the first connecting cylinder 921 moves upward, the first air inlet 9212 is attached to the wall of the second connecting cylinder 922 and sealed. Therefore, the air in the cavity 980 cannot enter the second receiving cavity 9220. The one-way air inlet valve 9211 on the first connecting cylinder 921 connects the cavity 980 and the connecting cavity 940 to replenish the air in the cavity 980.

[0081] When the pressing member 94 is pressed down again, the first connecting cylinder 921 moves downward first. During the movement, the first sealing part 942 on the pressing member 94 disengages from the side wall of the second connecting cylinder 922, thereby allowing the second receiving cavity 9220 and the first receiving cavity 930 to communicate with each other through the transport channel 970. Air is replenished to the first receiving cavity 930. Before the second sealing part 943 is attached to the wall of the base 91, external air enters into the container through the transport channel 970 to replenish the container. When the first connecting cylinder 921 moves downward, it squeezes the substance stored in the first receiving cavity 930, so that the substance is transported into the first receiving cavity 930 after passing through the infusion channel 960. Air in the cavity 980 is pumped into the second receiving cavity 9220 and mixed with the substance to generate foam. After foam is generated, it is pumped out from the outlet 941 through the connecting cavity 940. At the same time, the first connecting cylinder 921 and the second connecting cylinder 922 cooperate to expel the air in the first receiving cavity 930 again.
