Description

Technical Field

[0001] This invention relates to the field of aerosol packaging, and more specifically, to a two-component aerosol packaging device employing pressurized mixing. Background Technology

[0002] Aerosol packaging devices are widely used in various fields such as daily chemicals, pharmaceuticals, industrial cleaning, and disinfection due to their advantages of convenient use, good sealing performance, and uniform dispensing. For the storage and use of two-component materials, existing technologies mostly employ two methods: First, the two solutions are premixed and then filled into a single aerosol bottle. However, this method is only suitable for chemically stable materials that will not react, deteriorate, or become ineffective after long-term mixing. For two-component materials that are prone to oxidation, polymerization, or cross-linking reactions, or that require immediate mixing, premixing directly shortens the product's shelf life, leading to material ineffectiveness and failing to meet usage requirements. Second, a separate two-bottle packaging method is used, where the two materials are manually mixed before filling. This method is cumbersome, the mixing ratio is difficult to control precisely, and material leakage and contamination are prone to occur during mixing. Furthermore, it cannot achieve multiple quantitative mixing operations, and the remaining material after a single mixing is easily wasted, resulting in high operating costs.

[0003] While some existing two-component aerosol devices attempt to achieve isolated storage using a built-in liquid storage structure, they generally suffer from drawbacks such as complex structure, difficulty in triggering mixing, ability to achieve only single mixing, non-adjustable mixing ratio, and poor sealing reliability, making them unsuitable for the needs of multiple uses on demand in various scenarios. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a two-component aerosol packaging device that uses pressurized mixing, aiming to improve the problems of existing two-component aerosol packaging devices, such as materials being prone to premature reaction and failure, only being able to mix once, and the mixing ratio being uncontrollable.

[0005] This invention is implemented as follows: This invention provides a two-component aerosol packaging device using pressurized mixing, including a valve assembly mounted on the bottle body, a liquid storage pipe installed at the bottom of the valve assembly, a liquid storage container for storing solution A inside the bottle, the liquid storage container having a gas inlet and a liquid rupture outlet, both of which are covered with a sealing film, and solution B contained inside the bottle; after the air pressure breaks through the sealing film of the gas inlet, pressure is applied to the liquid storage container, and solution A inside the liquid storage container, under pressure, breaks through the sealing film inside the liquid rupture outlet, allowing solution A and solution B to mix, realizing instant, on-demand mixing of two-component materials.

[0006] Furthermore, a partition is provided inside the bottle to divide the bottle into an upper cavity and a lower cavity. The upper cavity is filled with high-pressure gas A. The partition has an opening that is aligned with the gas inlet. A control valve assembly A is provided inside the opening. When the control valve assembly A is opened, the high-pressure gas A filling the upper cavity breaks through the sealing film inside the gas inlet, thereby achieving precise conduction and pressure application of the high-pressure gas.

[0007] Furthermore, the lower cavity is filled with solution B and high-pressure gas B, and the liquid rupture port is connected to the liquid storage pipe to ensure that the mixed solution can be smoothly sprayed out through the valve assembly via the liquid storage pipe, thus ensuring smooth material discharge.

[0008] Furthermore, the liquid storage containers are in multiple sets, and the gas inlets on the multiple sets of liquid storage containers can be aligned with the opening; the liquid storage pipe also includes an external connecting pipe, which is L-shaped, with one end connected to the liquid storage pipe and the other end connected to the liquid rupture port; the bottom end of the liquid storage pipe is provided with a control valve assembly B, and by alternately opening and closing the two sets of control valve assemblies, the multiple sets of liquid storage containers can be used sequentially to complete multiple quantitative mixing and discharging.

[0009] Furthermore, the partition consists of an upper sealing ring and a lower sealing ring. The upper sealing ring is sealed to the outer wall of the liquid storage pipette, and the top of the lower sealing ring is provided with a threaded ring protrusion, while the bottom of the upper sealing ring is provided with a threaded sealing groove that aligns with the threaded ring protrusion. The split structure with threaded sealing cooperation reduces the processing difficulty of the bottle cavity, facilitates assembly, and ensures the sealing and isolation effect between the upper and lower cavities.

[0010] Furthermore, the outer wall of the liquid storage pipette is provided with a sealing ring, and the sealing ring and the bottom of the upper sealing ring are rotatably connected in a sealing manner. The liquid storage container is fixedly set at the bottom of the sealing ring, and the sealing ring is provided with a communication port corresponding to the gas inlet. By rotating the sealing ring, the alignment of different liquid storage containers with the partition opening can be achieved, and the liquid storage container to be used can be switched, which is simple to operate.

[0011] Furthermore, the control valve assembly A has a piercing tube connected to its opening via an elastic element. Under the action of the elastic element, the piercing tube pierces the sealing film inside the gas inlet, allowing high-pressure gas A to connect with the liquid storage container. This eliminates the need for complex electrical control structures, relying solely on mechanical triggering, resulting in high reliability and a long service life.

[0012] Furthermore, the outer connecting pipe has an annular puncture part at one end of the liquid storage container. When the sealing film inside the liquid rupture port bulges outward under the action of high-pressure gas A and contacts the annular puncture part, it punctures the sealing film inside the liquid rupture port, thereby reducing the difficulty of breaking the sealing film, ensuring the sensitivity of mixing triggering, and avoiding the problem of the film failing to break after pressure is applied and the mixing failing.

[0013] Furthermore, the control valve assembly B includes a control disc with a through hole, and the bottom of the liquid storage pipette is provided with a sealing part, which is a sealing disc with an alignment hole. When the through hole on the control disc aligns with the alignment hole, the liquid storage pipette and the lower cavity are connected, and the control disc and the sealing disc rotate in a sealed manner. The control disc is braked by a control rod coaxially arranged thereon, and the control rod and the valve stem in the valve assembly are fixed, realizing the linkage control between the valve assembly and the control valve assembly B, simplifying the operation process. The top of the control disc is provided with a buffer groove, and the opening of the buffer groove is provided with an elastic membrane. When the sealing membrane in the liquid rupture port bulges into the external connecting pipe, it buffers the compression of the liquid storage pipette by the solution A in the liquid storage pipe, avoiding the sudden increase in internal pressure that could damage the components and improving the stability of the device.

[0014] Furthermore, to control the mixing ratio of solution A and solution B, the liquid storage pipette is provided with an adjustment section that can extend into the liquid storage pipette. By changing the effective volume inside the liquid storage pipette, the mixing amount of solution B is adjusted, thereby precisely adjusting the mixing ratio of solution A and solution B to suit the mixing requirements of different materials.

[0015] The beneficial effects of this invention are: 1. Two-component isolated storage, significantly extending shelf life: Solution A is stored in an independent liquid storage container, while solution B is stored in the lower cavity of the bottle. With the help of a sealing film, complete sealing and isolation are achieved, preventing the two solutions from coming into contact and reacting prematurely. This is suitable for perishable two-component materials that need to be mixed immediately, effectively extending the product's shelf life.

[0016] 2. Multiple quantitative mixing is possible to avoid material waste: Multiple independent liquid storage containers are used with a rotatable sealing ring structure, so that one set of liquid storage containers can be used at a time. After use, the next set can be switched. This solves the drawback of traditional devices that can only mix once. The remaining material can be sealed and stored, which greatly reduces material waste and improves the economic efficiency of use.

[0017] 3. Precise and adjustable mixing ratio with strong adaptability: By changing the effective volume through the adjustment part in the liquid storage pipette, the feed amount of solution B can be precisely controlled, thereby adjusting the mixing ratio of the two-component solution. It can be adapted to the mixing requirements of different industries and materials, and has a wide range of applications.

[0018] 4. Simple structure and convenient processing and assembly: The partition adopts a split threaded sealing structure, which reduces the difficulty of bottle processing. All parts are mechanical structures with no complex electronic control components. The assembly process is simple, suitable for mass industrial production, and reduces production costs.

[0019] 5. Highly sensitive triggering and reliable sealing: It adopts a high-pressure gas pressure to puncture the sealing film, combined with the annular puncture part and puncture tube structure, resulting in high mixed triggering sensitivity. At the same time, each sealing part adopts multiple sealing designs such as sealing rings and threaded seals to avoid gas leakage and material seepage, ensuring high safety in use.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1-8 As shown, the core components of a pressurized mixing two-component aerosol packaging device include a bottle body 1, a valve assembly, a liquid storage pipette 2, a partition 10, and multiple sets of liquid storage containers 3. The assembly process is carried out in a top-to-bottom and inside-to-outside order, as follows: First, the partition 10 consists of an upper sealing ring 100 and a lower sealing ring 101. During assembly, the lower sealing ring 101 is fixedly snapped into a preset position on the inner wall of the bottle body 1 (in some embodiments, it can also be integrally formed with the bottle body 1) and sealed and fitted against the inner wall of the bottle body 1. Then, the upper sealing ring 100 is threadedly engaged with the threaded sealing groove through the threaded ring protrusion, and tightly connected with the lower sealing ring 101. After sealing and connecting, a complete partition 10 structure is formed. The partition 10 structure divides the bottle body 1 into an independent upper cavity and a lower cavity. Solution B is quantitatively filled into the lower cavity and high-pressure gas B is injected to complete the material sealing of the lower cavity. Then, high-pressure gas A is injected into the upper cavity to complete the sealing of the upper cavity, ensuring that there is no cross-contamination or leakage between the upper and lower cavities.

[0025] It should be added that the upper sealing ring 100 and the lower sealing ring 101 need to be sealed together. In some embodiments, the core principle of the sealing connection between the threaded ring protrusion and the threaded sealing groove is to use the thread to provide locking force + the ring groove / protrusion to form a precise line / surface seal. It is a combination structure of thread locking + end face / radial sealing. For example, it is composed of a groove and a sealing ring. An annular groove (sealing groove) is processed at the root of the thread or the end face of the threaded ring protrusion. An elastic sealing element such as an O-ring, rectangular ring, or combination washer is built in. When the thread is tightened, the sealing groove accurately positions the sealing ring, so that it is compressed axially / radially, and the elastic rebound force fills the gap, so that the sealing element and the groove wall and mating surface form a double seal.

[0026] The liquid storage pipette 2 is passed through the central through hole of the upper sealing ring 100 from top to bottom, and the two are sealed together. The sealing abutment ring 21 on the outer wall of the liquid storage pipette 2 is tightly fitted with the bottom of the upper sealing ring 100 to achieve a sealed rotational connection. Multiple sets of liquid storage containers 3, which are pre-filled with solution A and have their gas inlet 30 and liquid rupture outlet 31 sealed with sealing films, are evenly fixedly installed at the bottom of the sealing abutment ring 21 (fixed on the outer wall of the liquid storage pipette 2, and the fixing method can be any method such as snap-fit, interference fit or integral molding). Among them, the liquid storage pipette 2 is provided with an L-shaped external connecting pipe 20, the number of which is the same as the number of liquid storage containers 3. One end of the external connecting pipe 20 is sealed and connected to the side wall of the liquid storage pipette 2 (any method such as snap-fit, interference fit or integral molding can be used), and the other end is sealed and connected to the liquid rupture outlet 31 of the corresponding liquid storage container 3 (the connection method is the same as that with the liquid storage pipette 2).

[0027] It should be noted that the valve assembly is existing technology, and its structure includes a valve stem, a sealing ring, a sealing ring mounting base, and a valve stem spring. The valve stem has a through-hole, with the liquid inlet located on the valve stem sidewall. Initially, under the action of the valve stem spring, the liquid inlet of the through-hole is restricted to this position, and in this position, the liquid inlet of the through-hole is sealed by the sealing ring. During operation, when the valve stem is subjected to downward force, the liquid inlet of the through-hole disengages from the sealing ring, causing the inner cavity of the sealing ring mounting base to connect with the through-hole. Under the high pressure inside the bottle, the solvent inside the bottle is ejected from the through-hole of the valve stem. The valve stem spring is located between the bottom of the valve stem and the bottom of the sealing ring mounting base. The sealing ring mounting base is used to install the sealing ring, and the bottom of the sealing ring mounting base is connected to the liquid storage pipe 2.

[0028] In addition, the sealing membranes of the gas inlet and the liquid rupture outlet are pre-marked with grooves or weak areas. The grooves are in the shape of a cross, a line, or a ring to ensure directional and one-time rupture under high pressure, and to avoid debris clogging the pipeline.

[0029] Based on the above structural composition, its working process is as follows: In the first embodiment, when the liquid storage container 3 is a single container, it can be a bag or a tube, or any container capable of storing liquid. This aerosol packaging device has a simple structure, consisting only of the liquid storage container 3 set inside the bottle body 1 and a gas inlet 30 on which a gas delivery pipe can be installed. The gas delivery pipe can penetrate through the end of the bottle body and extend outward. In use, external high-pressure gas is delivered to the gas inlet 30 through the gas delivery pipe. After breaking through the sealing film inside the gas inlet 30, pressure is applied to the liquid storage container 3. The solution B inside the liquid storage container 3 is pressurized and breaks through the sealing film inside the liquid rupture port 31, allowing solution B to mix with solution A inside the bottle body 1.

[0030] In the second implementation method, when there are multiple liquid storage containers 3, the aerosol packaging device includes structural components such as a liquid storage straw 2, a partition 10, and multiple sets of liquid storage containers 3. The implementation process and working principle are as follows: In the initial standby state of the device, the high-pressure gas A inside the upper cavity, the solution B inside the lower cavity, and the solution A inside the storage container 3 are completely isolated and sealed, and do not come into contact with each other, ensuring the stability of the material during storage.

[0031] It should be added that, in order to ensure the airtightness of the high-pressure gas A inside the upper cavity, the solution B inside the lower cavity, and the solution A inside the storage container 3, this device is also equipped with control valve assembly A and control valve assembly B. Control valve assembly A is located in the opening of the upper sealing ring 100, and the opening is used for the flow-type alignment of the gas inlet 30 of each storage container 3. Control valve assembly B is located at the bottom end of the storage pipe 2. The bottom of the storage pipe 2 is sealed (sealing disc structure), but contains an alignment hole. After the control valve assembly B is opened, it aligns with the alignment hole, and the storage pipe 2 and the lower cavity can communicate.

[0032] Step 1, quantitative pre-filling of solution B: Manually rotate the sealing ring 21 to rotate one of the liquid storage containers 3, so that its gas inlet 30 is precisely aligned with the opening of the partition 10 (set on the upper sealing ring 100); then open the control valve assembly B. At this time, the control valve assembly A remains closed, and the high-pressure gas B in the lower chamber generates downward pressure, forcing solution B into the liquid storage pipette 2 until the internal space of the liquid storage pipette 2 is completely filled, thus realizing quantitative pre-filling of solution B. Keep the control valve assembly B open and ready for operation.

[0033] Reference Figure 3 In some embodiments, to facilitate the rotation of the braking sealing ring 21, the sealing ring 21 is fixed to the outer wall of the liquid storage tube 2, and the liquid storage tube 2 is fixed to the sealing ring mounting seat. That is, only braking the sealing ring mounting seat is needed to drive the sealing ring 21 to rotate. During installation, the sealing ring mounting seat can rotate to seal the top of the aerosol bottle. To ensure sealing, a sealing pressure ring 5 is provided on the top outer wall of the sealing ring mounting seat. The sealing pressure ring 5 is located above the top of the aerosol bottle and the corresponding opening of the sealing ring mounting seat, and the outer diameter of the sealing pressure ring 5 is larger than the inner diameter of the top of the aerosol bottle and the corresponding opening of the sealing ring mounting seat. Furthermore, a sealing ring is provided at the bottom of the sealing pressure ring 5. In use, rotating the outer wall of the sealing pressure ring 5 actuates the sealing ring mounting seat to rotate.

[0034] In other embodiments, to facilitate observation and to ensure that the opening on the partition 10 corresponds to the liquid storage container 3 below it, the sealing ring 5 is provided with an observation port 50. The top of the aerosol bottle is marked with markings corresponding to the number and position of the liquid storage containers 3, for example, the markings are one, two, three and four. Marking one corresponds to the position of the first liquid storage container 3, and correspondingly, marking one corresponds to the position of the second liquid storage container 3. The markings one, two, three and four are arranged in a concentric ring, and the angle between each is the same as the central angle between the four liquid storage containers 3.

[0035] Furthermore, in some embodiments, to ensure that the sealing ring mounting base does not rotate arbitrarily during use, an elastic positioning protrusion can be provided at the bottom of the sealing ring 5 or the top of the aerosol bottle. Correspondingly, an interference fit positioning groove corresponding to the elastic positioning protrusion is provided at the top of the aerosol bottle or the bottom of the sealing ring 5. When the observation port 50 rotates to positions marked one, two, three, and four, the elastic positioning protrusion is embedded into the interference fit positioning groove, achieving positioning of the sealing ring mounting base after rotation. The number of elastic positioning protrusions is one set, and the number and center angle of the interference fit positioning grooves are the same for the four liquid storage containers 3, ensuring positioning accuracy. It should be added that the elastic positioning protrusion can be a bent metal sheet or a spherical protrusion that extends into the top of the aerosol bottle or the bottom of the sealing ring 5. The spherical protrusion is maintained in an outward protruding state by an elastic element, which can be a spring or other elastic component.

[0036] The second step is to trigger the two-component mixing under pressure: close the control valve assembly B, and simultaneously trigger the control valve assembly A. The high-pressure gas A in the upper chamber breaks through the sealing film at the gas inlet 30 and rushes into the liquid storage container 3, causing the internal pressure of the liquid storage container 3 to rise rapidly. Under continuous pressure, the sealing film at the liquid rupture port 31 bulges outward and ruptures, allowing the solution A in the liquid storage container 3 to flow rapidly into the liquid storage pipe 2 and mix thoroughly with the pre-filled solution B inside to form a usable two-component mixed solution.

[0037] The third step is discharging and switching containers: Keep control valve assembly B closed and control valve assembly A open. Continuously press the valve assembly. Under the action of high-pressure gas A in the upper chamber, the mixed solution is pushed upward along the liquid storage pipe 2 and finally sprayed out evenly through the valve assembly, completing a single use. After the solution A in the group of liquid storage containers 3 is completely used up, rotate the sealing ring 21 to rotate the next group of liquid storage containers 3 to align with the opening of the partition 10. Repeat the above pre-filling, mixing, and discharging process to achieve multiple reuses until all the materials in the liquid storage containers 3 are used up.

[0038] It should be added that, in some embodiments, the structures of control valve assembly A and control valve assembly B can be configured as follows: The control valve assembly A is a puncture tube connected to the opening by an elastic element. Under the action of the elastic element, the puncture tube punctures the sealing film inside the gas inlet 30, allowing high-pressure gas A to connect with the liquid storage container 3. The puncture tube has a chimney-shaped structure, and its maximum outer diameter is smaller than the inner diameter of the opening, ensuring that high-pressure gas A in the upper cavity can pass through the opening. The elastic element can be a spring or a cylindrical structure with side openings. When it is a cylindrical structure with side openings, the puncture tube slides up and down along the inner wall of the cylindrical structure in a sealed manner, and the two will not separate. Under the action of high-pressure gas A, the puncture tube has a downward sliding tendency. When the opening and the gas... When the inlet 30 is aligned, the puncture tube moves downward under the action of high-pressure gas A, piercing the sealing film inside the gas inlet 30. The side opening is no longer blocked by the puncture tube, allowing the high-pressure gas A to enter the liquid storage container 3 through the inside of the cylindrical structure, the side opening, the opening, and the gas inlet 30 in sequence. The inner wall of the gas inlet 30 can be an arc-shaped structure, in the form of a bowl. As the sealing ring 21 rotates, the puncture tube slides upward along the inner wall of the bowl-shaped gas inlet 30 until it seals the side opening and abuts against the bottom of the puncture tube and the top of the sealing ring 21, ensuring the isolation between the upper cavity and the liquid storage tube 2.

[0039] In addition, in some embodiments, the rotation of the sealing ring 21 is achieved by the rotation of the liquid storage pipe 2, and the rotation of the liquid storage pipe 2 is achieved by the rotation of the sealing ring mounting seat in the valve assembly. In this case, the sealing ring mounting seat and the end cap of the bottle body 1 are sealed and rotated together, and the liquid storage pipe 2 and the partition 10 are also sealed and rotated together. In the implementation process, the sealing method can be achieved by conventional rotating sealing structures such as sealing rings.

[0040] The control valve assembly B includes a control disc with a through hole. The control disc and the sealing disc rotate in a sealed manner, which can be achieved by setting a sealing ring. Furthermore, the control disc is braked by a control rod coaxially arranged thereon, and the control rod and the valve stem in the valve assembly are fixed, but the liquid inlet of the valve stem is not blocked. In use, the valve cap installed on the valve assembly is removed, and the valve stem is rotated. Preferably, to prevent the valve stem from rotating arbitrarily during use, a positioning protrusion is provided at the outer end of the valve stem or inside the valve cap. Correspondingly, two positioning grooves are provided inside the valve cap or at the outer end of the valve stem, corresponding to the positioning protrusion. One positioning groove corresponds to the alignment state of the through hole and the alignment hole, and the other positioning groove corresponds to the misalignment state of the through hole and the alignment hole.

[0041] In addition, in some embodiments, the top of the control panel is provided with a buffer groove, and an elastic membrane is provided at the opening of the buffer groove. When the sealing membrane in the liquid burst port 31 bulges into the external connecting pipe 20, the deformation of the elastic membrane absorbs the squeezing force of the solution A in the liquid storage pipe 2 on the liquid storage pipe 2.

[0042] Implementation method three: Mixing ratio adjustment operation. For specific mixing ratio requirements of different two-component materials, the mixing ratio can be precisely controlled by adjusting the adjusting part 4 inside the liquid storage pipette 2. The adjusting part 4 moves up and down along the inner wall of the liquid storage pipette 2, changing the position of the adjusting part 4 extending into the liquid storage pipette 2, thereby adjusting the effective volume inside the liquid storage pipette 2. If it is necessary to increase the proportion of solution B, the adjusting part 4 is adjusted upward to expand the effective volume of the liquid storage pipette 2, and the pre-filling amount of solution B increases accordingly. If it is necessary to increase the proportion of solution A, the adjusting part 4 is adjusted downward to reduce the effective volume of the liquid storage pipette 2, and the pre-filling amount of solution B decreases accordingly. Ultimately, the mixing ratio of the two components can be precisely controlled as needed to adapt to different application scenarios.

[0043] In some embodiments, the adjusting part 4 may be a sliding seat that slides and seals along the inner wall of the liquid storage pipette 2. Preferably, the sliding seat may be threadedly connected to the outer wall of the control rod (the upper part of the control rod has a threaded section, and the sliding seat has a threaded groove corresponding to the control rod, and the end of the threaded groove and the control rod are sealed and slid together by a sealing ring). The inner wall of the liquid storage pipette 2 has a prismatic structure to prevent the sliding seat from rotating. The sliding seat is located above the connection between the outer connecting pipe 20 and the liquid storage pipette 2. By moving the sliding seat, the effective storage capacity of the solution B between the bottom of the sliding seat and the top of the sealing plate is changed.

[0044] Reference Figure 3 In some other embodiments, to facilitate recording the downward movement distance of the sliding seat 4, in this embodiment, a threaded ring seat 6 slides along the length of the valve stem outer wall in the valve assembly (the inner wall of the threaded ring seat 6 is provided with a sliding protrusion, and the outer wall of the valve stem is provided with a groove corresponding to the sliding protrusion, ensuring that the threaded ring seat 6 can drive the valve stem to rotate synchronously during rotation). Furthermore, the threaded ring seat 6 and the top of the sealing ring mounting seat are threadedly connected. Therefore, when the threaded ring seat 6 rotates, driving the valve stem to rotate synchronously, the distance between the top of the threaded ring seat 6 and the top of the sealing ring mounting seat will change relatively (due to the threaded connection between the threaded ring seat 6 and the sealing ring mounting seat). Initially, under the action of the valve stem spring, the position of the valve stem in the valve assembly remains the same. However, due to the change in position after the threaded ring seat 6 rotates... If the position changes, the initial position of the top surface of the threaded ring seat 6 relative to the outer wall of the valve stem will change in the initial state of the valve stem. The downward movement distance of the sliding seat 4 is recorded or read through the above position change. For example, if there is a scale on the outer wall of the valve stem along the length of the valve stem, in the initial state, the value read by the top surface of the threaded ring seat 6 relative to the scale is C. After the sliding seat 4 moves, the value read by the top surface of the threaded ring seat 6 relative to the scale is D. Then the position difference between the top surface of the threaded ring seat 6 and the outer wall of the valve stem is Z=CD. When the threaded ring seat 6 rotates one revolution, the vertical distance moved by the top surface of the threaded ring seat 6 relative to the top surface of the sealing ring mounting seat is F. Then the number of revolutions of the valve stem is Q=Z / F. Furthermore, when the valve stem rotates one revolution, the vertical movement distance of the sliding seat 4 is G. Then the actual movement distance of the sliding seat 4 is Q times G.

[0045] Finally, the core components of this device have been specifically optimized to balance practicality and ease of processing: the partition 10 adopts a split threaded sealing structure, which is easier to develop molds, simpler to form, and has a higher sealing fit compared to an integrated partition, effectively preventing high-pressure gas from entering the cavity; the buffer groove and elastic membrane on the top of the control panel can effectively buffer the instantaneous impact pressure generated by the instantaneous influx of solution A, protecting the liquid storage pipe and various sealing components, and preventing damage to components caused by sudden pressure increases; the sealing and rotating structure of the sealing ring 21 and the upper sealing ring 100 allows switching of the liquid storage container 3 without disassembling the device, ensuring a fully sealed operation, eliminating material contamination and leakage, and making operation convenient and efficient.
