Description

Technical Field

[0001] The embodiments of the present invention relate to a foaming device, and more particularly to a gas-liquid mixing chamber, a foaming mechanism, a foam pump, and a foaming method. Background Technology

[0002] Non-foaming liquid phases, such as makeup remover oils and amino acid solutions, require effective dispersion, either by forming bubbles or a thin film, to disperse and diffuse well in the air or when applied to objects or skin. However, current methods or devices cannot achieve automated and effective dispersion or foaming of non-foaming liquid phases.

[0003] Foam pumps are commonly used in daily life and in the medical field for washing and medical products, such as hand sanitizer dispensers. These products mix liquid and gaseous media to create foam before use.

[0004] Currently, if non-foaming phase media are to be effectively dispersed or foamed using a foam pump to form a good foam morphology, the following technical problems exist:

[0005] 1. Current foam pumps can generally only foam the foaming phase medium. If the non-foaming phase medium is to be mixed with the foaming phase medium and pumped out, most of the two media are immiscible and will separate into layers. In the case of separation, the non-foaming phase medium and the foaming phase medium cannot be pumped out and foamed in an effective matching ratio.

[0006] 2. If a non-foaming phase medium enters the foam of the foam pump, the non-foaming phase medium will inhibit the formation of foam to a certain extent, thus causing defoaming.

[0007] 3. When the foam pump uses in-pump foaming, the foamed medium needs to flow a certain distance after being pumped out of the pump before entering the nozzle. This flow distance often causes the generated foam to defoam, resulting in an unsatisfactory foam shape pumped out from the nozzle. Summary of the Invention

[0008] The purpose of this invention is to provide a gas-liquid mixing chamber, a foaming mechanism, a foam pump, and a foaming method. This invention not only enables the simultaneous pumping out of the non-foaming phase medium, the foaming phase medium, and the gaseous medium after foaming, but also avoids, to a certain extent, the non-foaming phase medium inhibiting the formation of foam in the foaming phase medium, prevents stratification caused by the immiscibility of the foaming and non-foaming phase media, and prevents defoaming caused by excessively long transmission distances.

[0009] To achieve the above objectives, embodiments of the present invention provide a gas-liquid mixing chamber, comprising:

[0010] At least two inlet chambers are provided, each for receiving the liquid medium pumped out from the pumping mechanism.

[0011] At least one air inlet chamber is provided for receiving the gaseous medium pumped out from the pumping mechanism;

[0012] The gas-liquid mixing chamber is also used to mix the liquid medium in each of the liquid inlet chambers and the gas medium in each of the gas inlet chambers.

[0013] In addition, embodiments of the present invention also relate to a foaming mechanism, comprising:

[0014] The gas-liquid mixing chamber as described above;

[0015] Wherein, at least one of the liquid inlet chambers receives a non-foaming phase medium, and at least one of the liquid inlet chambers receives a foaming phase medium.

[0016] In addition, embodiments of the present invention also relate to a foaming mechanism, comprising:

[0017] The gas-liquid mixing chamber as described above;

[0018] Wherein, at least one of the liquid inlet chambers receives a non-foaming phase medium, and at least one of the liquid inlet chambers receives a foaming phase medium.

[0019] In addition, embodiments of the present invention also relate to a foam pump, comprising:

[0020] The gas-liquid mixing chamber as described above;

[0021] A nozzle, connected to the gas-liquid mixing chamber, is used to spray out the mixture after it has been mixed and foamed by the gas-liquid mixing chamber.

[0022] The pumping mechanism is used to pump liquid medium into each of the liquid inlet chambers and gas medium into each of the gas inlet chambers.

[0023] In addition, embodiments of the present invention also relate to a foaming method, comprising the following steps:

[0024] The device receives a gaseous medium pumped out from a pumping mechanism and at least two liquid media; wherein, of the received liquid media, at least one is a non-foaming phase medium and at least another is a foaming phase medium.

[0025] The liquid medium and the gaseous medium are mixed and foamed;

[0026] Under the pressure of the pumping mechanism, the mixture formed by the foaming process is pumped out.

[0027] Compared with the prior art, the embodiments of the present invention include a gas-liquid mixing chamber comprising at least two liquid inlet chambers and at least one air inlet chamber. At least one liquid inlet chamber is used to receive a non-foaming phase liquid medium pumped from the pumping mechanism, and at least another liquid inlet chamber is used to receive a foaming phase liquid medium pumped from the pumping mechanism. Furthermore, the gas-liquid mixing chamber is also used to mix and foam the liquid medium in each liquid inlet chamber and the gas medium in each air inlet chamber, and to directly pump out the mixture formed after mixing and foaming. This allows the non-foaming phase medium to be pumped out along with the foaming phase medium after mixing and foaming with the gas medium. This not only alleviates the defoaming phenomenon caused by excessively long media transport distances to a certain extent, but also prevents the non-foaming phase medium from inhibiting the formation of foam in the foaming phase medium, and prevents stratification caused by the immiscibility of the foaming and non-foaming phase media. This ensures that the medium pumped from the nozzle has a good foam morphology.

[0028] In addition, the pumping mechanism simultaneously pumps out at least one non-foaming phase medium, at least one foaming phase medium, and a gaseous medium. The foam generated during the foaming process of the foaming phase medium and the gaseous medium allows the non-foaming phase medium to adhere to the inside or outside of the bubbles in the foaming phase medium, forming a foam layer of gas and foaming phase medium and a thin film layer of non-foaming phase medium. During this process, because the foam layer formed by the foaming phase medium has a large specific surface area, the non-foaming phase medium is more likely to adhere to it after dispersion and disperse between the bubbles and the foam formed by the foaming phase medium, and then pumped out of the gas-liquid mixing chamber. The resulting mixture of the foam layer of gas and foaming phase medium and the thin film layer of non-foaming phase medium is more easily dispersed and applied to objects or skin.

[0029] The gas-liquid mixing chamber also includes:

[0030] At least two liquid outlet chambers are provided for supplying liquid media to the pumping mechanism, wherein at least one of the liquid outlet chambers is used to supply a non-foaming phase liquid media to the pumping mechanism, and at least one of the liquid outlet chambers is used to supply a foaming phase liquid media to the pumping mechanism.

[0031] At least one vent is provided for supplying a gas medium to the pumping mechanism.

[0032] In addition, each of the liquid inlet chambers and each of the air inlet chambers are connected sequentially along a preset direction, so that the liquid medium entering each of the liquid inlet chambers and the gas medium entering each of the air inlet chambers are mixed sequentially along the preset direction.

[0033] In addition, the gas-liquid mixing chamber also includes:

[0034] A dispersion component includes: multiple partitions, wherein each partition is arranged sequentially along the preset direction;

[0035] Wherein, along the preset direction, any one of the partitions is used to separate two interconnected liquid inlet chambers or two interconnected air inlet chambers; or, any one of the partitions is used to separate the interconnected liquid inlet chamber and the air inlet chamber;

[0036] Each of the partitions is also provided with a dispersion structure that allows gaseous and liquid media to pass through.

[0037] In addition, the number of liquid inlet chambers and air inlet chambers are the same and they correspond uniquely. Each liquid inlet chamber is connected to the unique corresponding air inlet chamber, so that the liquid medium entering each liquid inlet chamber can enter the unique corresponding air inlet chamber and mix with the gas medium entering the unique corresponding air inlet chamber.

[0038] The gas-liquid mixing chamber also includes:

[0040] In addition, the gas-liquid mixing chamber also includes:

[0041] A dispersion component includes: multiple partitions; wherein each liquid inlet chamber is provided with a partition between itself and a uniquely corresponding air inlet chamber, and each partition is further provided with a dispersion structure that allows the liquid medium to pass through.

[0042] In addition, the gas-liquid mixing chamber also includes:

[0043] A dispersing element is disposed between each of the air intake chambers and the mixing chamber;

[0044] The dispersing element is used to disperse the gas-liquid mixture entering the mixing chamber.

[0045] In addition, the dispersion structure consists of multiple notches respectively provided on each of the partitions.

[0046] In addition, each of the partitions has a lower edge and an upper edge opposite to the lower edge; wherein the notch on each partition is provided at the upper edge or the lower edge of the partition.

[0047] In addition, the gas-liquid mixing chamber has an opening side that can be sealed and a receiving side opposite to the opening side; wherein each of the liquid inlet chambers and the air inlet chambers is located on the receiving side;

[0048] The gas-liquid mixing chamber also has:

[0049] There are at least two liquid inlet sides, the same number as the number of liquid inlet chambers, and they are uniquely corresponding; each liquid inlet side is disposed in the uniquely corresponding liquid inlet chamber, and any liquid inlet chamber is used to receive the liquid medium pumped out from the pumping mechanism through the uniquely corresponding liquid inlet side;

[0051] In addition, the liquid inlet side includes at least one liquid inlet hole provided on the receiving side, and each liquid inlet hole extends in a direction away from the opening side;

[0052] The air intake side includes at least one air intake hole disposed on the receiving side, and each air intake hole extends in a direction away from the opening side.

[0071] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of the present invention to facilitate a better understanding of this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0072] Example 1

[0073] The first embodiment of the present invention relates to a gas-liquid mixing chamber, such as... Figure 1 As shown, it includes at least two liquid inlet chambers 12 and at least one air inlet chamber 14. Each liquid inlet chamber 12 is used to receive liquid media pumped out from the pumping mechanism. Simultaneously, each air inlet chamber 14 is used to receive gaseous media pumped out from the pumping mechanism.

[0074] In addition, the gas-liquid mixing chamber 1 of this embodiment is also used to mix the liquid medium in each liquid inlet chamber 12 and the gas medium in each air inlet chamber 14.

[0075] It is easy to see from the above that the foaming mechanism 1 includes at least two liquid inlet chambers 12 and at least one air inlet chamber 14. Each liquid inlet chamber 12 is used to receive the liquid medium pumped out by the pumping mechanism. In addition, the gas-liquid mixing chamber is also used to mix the liquid medium in each liquid inlet chamber 12 and the gas medium in each air inlet chamber 14. This allows the non-foaming phase medium to be pumped out along with the foaming phase medium after mixing with the gas medium. It can also alleviate the defoaming phenomenon caused by excessively long medium transportation distance to a certain extent, and prevent the non-foaming phase medium from inhibiting the formation of foam in the foaming phase medium, and prevent the stratification phenomenon caused by the inability of the foaming phase medium and the non-foaming phase medium to dissolve.

[0076] In addition, the pumping mechanism simultaneously pumps out at least one non-foaming phase medium, at least one foaming phase medium, and a gaseous medium. The foam generated during the foaming process of the foaming phase medium and the gaseous medium allows the non-foaming phase medium to adhere to the inside or outside of the bubbles in the foaming phase medium, forming a foam layer of gas and foaming phase medium and a thin film layer of non-foaming phase medium. During this process, because the foam layer formed by the foaming phase medium has a large specific surface area, the non-foaming phase medium is more likely to adhere to it after dispersion and disperse between the bubbles and the foam formed by the foaming phase medium, and then pumped out of the gas-liquid mixing chamber. The resulting mixture of the foam layer of gas and foaming phase medium and the thin film layer of non-foaming phase medium is more easily dispersed and applied to objects or skin.

[0077] For example, in some implementations, such as Figure 1As shown, both the liquid inlet chamber 12 and the air inlet chamber 14 are provided in twos, and the two liquid inlet chambers 12 can be uniquely matched with the two air inlet chambers 14, that is, combined with Figure 5 As shown, the liquid inlet chamber 12a is correspondingly arranged with the air inlet chamber 14a, and the liquid inlet chamber 12b is correspondingly arranged with the air inlet chamber 14b. Furthermore, the liquid inlet chamber 12a is connected to the air inlet chamber 14a, allowing the liquid medium entering each of the liquid inlet chambers 12a to enter the air inlet chamber 14a and mix with the gaseous medium entering the air inlet chamber 14a. Similarly, the liquid inlet chamber 12b is connected to the air inlet chamber 14b, allowing the liquid medium entering the liquid inlet chamber 12b to enter the air inlet chamber 14b and mix with the gaseous medium entering the air inlet chamber 14b. Additionally, to ensure that the liquid mixture in the air inlet chamber 14a can mix with the gas-liquid mixture in the air inlet chamber 14b, as follows... Figure 5 As shown, the gas-liquid mixing chamber 1 of this embodiment further includes a mixing chamber 103, which is connected to both the air inlet chamber 14b and the air inlet chamber 14a. This allows the mixing chamber 103 to receive the gas-liquid mixing media mixed in the air inlet chambers 14b and 14a respectively, and to mix the gas-liquid mixing media to obtain a mixture with a foamy form. For example, in some embodiments, such as... Figure 5 As shown, when the liquid inlet chamber 12a receives a foaming phase medium pumped out from the pumping mechanism, and the liquid inlet chamber 12b receives a non-foaming phase medium pumped out from the pumping mechanism, the gas-liquid mixture containing the foaming phase medium and the gas-liquid mixture containing the non-foaming phase medium can be mixed through the mixing chamber 103. Therefore, the oil phase liquid medium can be pumped out together after the foaming phase medium and the gas medium are mixed and foamed, and the non-foaming phase medium can be effectively prevented from stratifying with the foaming phase medium.

[0078] In addition, it is worth mentioning that, such as Figure 1 and Figure 5 As shown, the gas-liquid mixing chamber 1 of this embodiment further includes at least two liquid outlet chambers 11 and at least one gas outlet 13. Each liquid outlet chamber 11 is used to supply a liquid medium to the pumping mechanism, while each gas outlet 13 is used to supply a gaseous medium to the pumping mechanism. Furthermore, in this embodiment, at least one liquid outlet chamber 11 supplies a non-foaming phase liquid medium to the pumping mechanism, while at least one liquid outlet chamber 11 supplies a foaming phase liquid medium. Therefore, in application, each liquid outlet chamber 11 can supply a liquid medium to the pumping mechanism of the foam pump, and each gas outlet 13 can supply a gaseous medium to the pumping mechanism. This allows the gas-liquid mixing chamber of this embodiment to not only mix gaseous and liquid media, but also to supply both liquid and gaseous media to the pumping mechanism under negative pressure, resulting in a more compact structure for the entire foam pump.

[0079] Furthermore, in order to better mix the foamed phase medium entering the intake chamber 14a and the non-foamed phase medium entering the intake chamber 14b with the gas medium, such as... Figure 1 and Figure 5 As shown, the gas-liquid mixing chamber 1 also includes a dispersion component 15, which includes two partitions 152. One partition 152 separates the liquid inlet chamber 12a from the air inlet chamber 14a, while the other partition 152 separates the liquid inlet chamber 12b from the air inlet chamber 14b. Each partition 152 is also provided with a dispersion structure 151 that allows the liquid medium to pass through. Through the dispersion structure 151 on each partition 152, when the foamed phase medium enters the air inlet chamber 14a and the non-foamed phase medium enters the air inlet chamber 14b, the foamed phase medium and the non-foamed phase medium are dispersed into small particles, respectively, so that the foamed phase medium and the non-foamed phase medium can be more thoroughly mixed with the gas medium. Furthermore, it should be noted that in this embodiment, as... Figure 5 As shown, the dispersion structure 151 consists of multiple notches 1511 disposed on the partition plate 152. Through the notches 1511 on each partition plate 152, the passing foamed phase medium and non-foamed phase medium can be dispersed into small particles, so that the foamed phase medium can achieve better mixing and foaming with the gas medium. Furthermore, since the non-foamed phase medium is also dispersed into several small particles by the notches 1511 on the partition plate 152, the non-foamed phase medium can also avoid the phenomenon of stratification between it and the foamed phase medium when the foamed phase medium and the gas medium are mixed and foamed.

[0080] Additionally, it is worth noting that, in order for the baffle 152 to more effectively disperse the liquid medium entering the air intake chamber 14 through the notches 1511, such as... Figure 1 As shown, the partition 152 has a lower edge 1521 and an upper edge 1522 opposite to the lower edge 1521 along a preset axis. Meanwhile, notches 1511 on the partition 152 are disposed on the upper edge 1522. Furthermore, the notches 1511 can be equidistantly arranged along the upper edge 1522, thereby dispersing the liquid medium entering the air intake chamber 14 into multiple uniformly sized small particles. This allows the liquid medium entering the air intake chamber 14 to fully mix with the gas medium entering the air intake chamber 14, thereby generating foam. Of course, in practical applications, the notches 1511 on the partition 152 are also disposed on the lower edge 1521 of the partition 152. This arrangement allows each partition 152 to also have the function of dispersing the liquid medium. In this embodiment, the position of the notches 1511 on the partition 152 is not specifically limited.

[0081] Furthermore, as a preferred embodiment, in some implementations, such as Figure 1 and Figure 5As shown, the gas-liquid mixing chamber 1 further includes a dispersing member 104, which is disposed between each air inlet chamber 14 and the gas-liquid mixing chamber 103. The dispersing member 104 is used to disperse the gas-liquid mixing medium entering the mixing chamber 103. It is evident that by using the dispersing member 104 to further disperse the gas-liquid mixing medium entering the gas-liquid mixing chamber 103, the foaming phase medium, the non-foaming phase medium, and the gaseous medium can be more fully mixed and foamed in the mixing chamber 103. This results in finer foam being produced from the mixture ejected from the gas-liquid mixing chamber, reducing defoaming by at least 30%. Furthermore, it should be noted that in this embodiment, as... Figure 1 As shown, the dispersing component 104 is a filter screen. The filter pores on the filter screen 104 further disperse the gas-liquid mixture, resulting in finer foam from the medium ejected from the gas-liquid mixing chamber 1. It should be noted that in this embodiment, the dispersing component 104 is only described using a filter screen as an example. In actual applications, other components with distributed micropores can also be used as the dispersing component 104. In this embodiment, the structure and type of the dispersing component 104 are not specifically limited.

[0082] In addition, through Figure 1 and Figure 2 It is easy to see that the gas-liquid mixing chamber of this embodiment also has a sealable opening side 16 and a receiving side 17 opposite to the opening side 16. Meanwhile, each liquid inlet chamber 12, each air inlet chamber 14, liquid outlet chamber 11, air outlet 13, and dispersion assembly 15 are all disposed on the receiving side 17. Furthermore, it is worth mentioning that, in order to enable the pumping mechanism to extract the liquid medium from each liquid outlet chamber 11, and simultaneously enable the pumping mechanism to pump the extracted liquid medium into the liquid inlet chamber 12, as shown... Figure 1 As shown, the gas-liquid mixing chamber 1 of this embodiment further includes: at least one liquid inlet 18 and at least one liquid outlet 19. The number of liquid inlets 18 is the same as the number of liquid outlet chambers 11, and they correspond uniquely. Furthermore, each liquid inlet 18 is connected to its unique corresponding liquid outlet chamber 11. Next, as... Figure 1 As shown, the number of liquid outlets 19 is the same as the number of liquid outlet chambers 11 and they correspond uniquely. Each liquid outlet 19 is located on the receiving side 17 and extends in a direction away from the opening side 16. At the same time, each liquid outlet 19 is connected to the unique corresponding liquid outlet chamber 11. Furthermore, any liquid outlet chamber 11 is used to provide liquid medium to the pumping mechanism through the unique corresponding liquid outlet 19.

[0083] Furthermore, in order to enable the pumping mechanism to pump the obtained gaseous and liquid media into the liquid inlet chamber 12 and the gas inlet chamber 14 respectively, such as Figure 1As shown, the gas-liquid mixing chamber also has at least two liquid inlet sides and at least two air inlet sides. The number of liquid inlet sides is the same as the number of liquid inlet chambers 12, and they are uniquely corresponding. Each liquid inlet side is located within a uniquely corresponding air inlet chamber 12. Furthermore, any liquid inlet chamber 12 can receive liquid medium pumped out from the pumping mechanism through its uniquely corresponding liquid inlet side. Similarly, the number of air inlet sides is the same as the number of air inlet chambers 14, and they are uniquely corresponding. Each air inlet side is located within a uniquely corresponding air inlet chamber 14. Furthermore, any air inlet chamber 14 can receive gaseous medium pumped out from the pumping mechanism through its uniquely corresponding air inlet side.

[0084] Specifically, in this embodiment, such as Figure 1 As shown, the liquid inlet side includes at least one liquid inlet hole 10 disposed on the receiving side 17, and each liquid inlet hole 10 extends in a direction away from the opening side 16, so that each liquid inlet chamber 12 can receive the liquid medium pumped out from the pumping mechanism through the liquid inlet hole 10 in the uniquely corresponding liquid inlet side. Similarly, in conjunction with Figure 4 As shown, the air intake side includes at least one air inlet 1001 disposed on the receiving side 17, and each air inlet 1001 extends in a direction away from the opening side 16, so that each air intake chamber 14 can receive the gas medium pumped out from the pumping mechanism through the air inlet 1001 in the uniquely corresponding air intake side. It is also worth noting that, in some embodiments, when multiple liquid inlets 10 on each liquid intake side and multiple air inlets 1001 on each air intake side are provided, such as... Figure 1 and Figure 4 As shown, each liquid inlet hole 10 on each liquid inlet side can be distributed in an array on the receiving side 17. For example, each liquid inlet hole 10 on any liquid inlet side can be arranged in a ring array or a rectangular array. Similarly, each air inlet hole 1001 on each air inlet side can also be distributed in an array on the receiving side 17. It is easy to see that multiple liquid inlet holes 10 can increase the delivery rate of the liquid medium when the pumping mechanism pumps liquid into the liquid inlet chamber 12. At the same time, multiple air inlet holes 1001 can increase the delivery rate of the gas medium when the pumping mechanism pumps air into the air inlet chamber 14.

[0085] Furthermore, it is worth noting that since the proportions of gas and liquid components vary in different mixtures, in order to achieve a reasonable match between the proportions of gaseous medium, foaming phase medium, and non-foaming phase medium in different mixtures, and to generate foam with a better morphology, in this embodiment, the number of air inlets 1001 in each air inlet chamber 14 can be set differently. Similarly, the number of liquid inlets 10 in each liquid inlet chamber 12 can be set differently. Therefore, by increasing or decreasing the number of air inlets 1001 in each air inlet chamber 14, and by increasing or decreasing the number of liquid inlets 10 in each liquid inlet chamber 12, different flow rates can be achieved in different liquid inlet chambers 12 and different air inlet chambers 14 during air intake, allowing the gas and liquid media to achieve different proportions as needed during foaming of different mixtures. However, in practical applications, the number of air inlets 1001 in each air inlet chamber 14 can also be set to the same, and similarly, the number of liquid inlets 10 in each liquid inlet chamber 12 can be set to the same.

[0086] Similarly, as an alternative, to allow different flow rates of liquid medium entering each liquid inlet chamber and different flow rates of gas medium entering each air inlet chamber, the diameters of the air inlets in each air inlet chamber and the diameters of the liquid inlets in each liquid inlet chamber can be set differently. This method can also satisfy the required ratio of gas and liquid media during foaming of different mixtures.

[0087] In addition, such as Figure 2 As shown, the gas-liquid mixing chamber of this embodiment also has a bottom side 102 opposite to the receiving side 17, and the receiving side 17 is located between the bottom side 102 and the opening side 16. To facilitate the gas-liquid mixing chamber receiving the liquid and gaseous media pumped out by the pumping mechanism, such as... Figure 4 As shown, the bottom side 102 is also provided with a plurality of liquid inlet grooves 105, and the number of liquid inlet grooves 105 is the same as the number on the liquid inlet side, and they are uniquely corresponding. Each liquid inlet groove 105 is connected to each liquid inlet hole 10 on the uniquely corresponding liquid inlet side. Simultaneously, the bottom side 102 is also provided with a plurality of air inlet grooves 106, and the number of air inlet grooves 106 is the same as the number on the air inlet side, and they are uniquely corresponding. Each air inlet groove 106 is connected to each air inlet hole 1001 on the uniquely corresponding air inlet side. Therefore, when the pumping mechanism provides liquid medium to each liquid inlet chamber 12 of the gas-liquid mixing chamber and gas medium to each air inlet chamber 14, it is only necessary to connect each liquid inlet groove 105 and air inlet groove 106 to the pumping mechanism to easily provide liquid medium to each liquid inlet chamber 12 and gas medium to each air inlet chamber 14. Furthermore, as a preferred embodiment, in some implementations, such as... Figure 4As shown, at least one pressure balancing groove 1021 is also provided on the bottom side 102, and at least one pressure balancing groove 1021 is provided between any two adjacent air inlet grooves 106. By connecting any two adjacent air inlet grooves 106 through the pressure balancing groove 1021, the pumping mechanism can ensure the consistency of air pressure in each air inlet chamber 14 when pumping gas medium into each air inlet chamber 14, and avoid the phenomenon that the air pressure in some air inlet chambers 14 is too high or too low, so that the ratio of gas medium to liquid medium can always be maintained at the preset ratio.

[0088] In addition, combined Figure 2 It is not difficult to see that the gas-liquid mixing chamber of this embodiment also includes at least one boss 100 and at least one check valve 101. The number of bosses 100 and check valves 101 are the same as the number of air inlet chambers 14, and they correspond uniquely. Each boss 100 is disposed within its unique corresponding air inlet chamber 14; that is, each boss 100 is formed by a portion of its receiving side 17 protruding towards its opening side 16. Simultaneously, each air inlet hole 1001 in each air inlet side is disposed on a boss 100. Furthermore, it is worth noting that, as... Figure 1 and Figure 2 As shown, each check valve 101 is respectively disposed in a unique corresponding air intake chamber 14, and is slidably connected to the boss 100 in the unique corresponding air intake chamber 14, so that each check valve 101 can slide relative to the receiving side 17. Therefore, when any check valve 101 slides to the first preset position in the direction towards the receiving side 17, as... Figure 2 As shown, the check valve 101 can directly close the intake side of the unique corresponding intake chamber 14, and when any check valve 101 slides to the second preset position in a direction away from the receiving side 17, the check valve 101 can directly open the intake side of the unique corresponding intake chamber 14.

[0089] It is worth noting that, in order for the check valve 101 to open or close the air inlet 1001, such as Figure 2 and Figure 3 As shown, the check valve 101 includes: a shaft portion 1011 slidably connected to the boss 100 along a predetermined axial direction, and a closing portion 1012 disposed at one end of the shaft portion 1011. In this embodiment, the closing portion 1012 has an umbrella-shaped structure. The shaft portion 1011 includes: a shaft body 10111 coaxially connected to the closing portion 1012, and a limiting protrusion 10112 coaxially connected to the shaft body 10111. The limiting protrusion 10112 is formed by a portion of the outer surface of the shaft body 10111 protruding outwards, allowing the limiting protrusion 10112 to abut against the side of the boss 100 opposite to the outlet side 16.

[0090] Therefore, in practical applications, combined with Figure 2 and Figure 3As shown, when the pumping mechanism pumps gas into the intake chamber 14, the gas acts on the closing part 1012 of the check valve 101, allowing the closing part 1012 of the check valve 101 to slide away from the receiving side 17 under the sliding fit between the shaft 10111 and the boss 100, thereby opening the intake port 1001 on the intake side. Conversely, when the pumping mechanism stops pumping gas into the intake chamber 14, the closing part 1012 of the check valve 101 can automatically fall down by its own weight, allowing the closing part 1012 of the check valve 101 to re-close the intake ports 1001 on the intake side. Therefore, it can effectively prevent the liquid medium entering the intake chamber 14 from entering the pumping mechanism through the intake port 1001 and causing damage to the pumping mechanism.

[0091] Furthermore, it should be noted that in this embodiment, since at least one liquid inlet chamber 12 receives a foaming phase medium, which can be an aqueous phase medium, and at least another liquid inlet chamber 12 receives a non-foaming phase medium, which can be an oil phase medium, the final mixture obtained by the gas-liquid mixing chamber of this embodiment contains not only a foaming phase medium but also a non-foaming phase medium, such as makeup remover oil. However, in practical applications, each liquid inlet chamber 12 of the gas-liquid mixing chamber of this embodiment can also be adapted to receive only foaming phase media, so that the mixture obtained by the gas-liquid mixing chamber foaming can contain only one or more foaming phase media, such as serums or facial cleansers.

[0092] However, it is worth noting that the aqueous phase medium mentioned in this embodiment can be an aqueous solution of anionic surfactants, amphoteric surfactants, or nonionic surfactants, while the oil phase medium can be a solution of substances that cannot be directly foamed, such as vegetable oil (e.g., makeup remover oil), vitamin C solution, amino acid solution, niacinamide solution, or mineral oil. Therefore, the mixture obtained after mixing and foaming in the gas-liquid mixing chamber of this embodiment can form other foaming mixtures besides makeup remover oil.

[0093] Example 2

[0094] The second embodiment of the present invention relates to a gas-liquid mixing chamber. The second embodiment is largely the same as the first embodiment, with the main difference being that, in this embodiment, to achieve mixing of the liquid and gaseous media, each liquid inlet chamber 12 and each gas inlet chamber 14 are sequentially connected along a predetermined direction, so that the liquid medium entering each liquid inlet chamber 12 and the gaseous medium entering each gas inlet chamber 14 can be sequentially mixed along the predetermined direction. For example, as... Figure 6As shown, both the liquid inlet chamber 12 and the air inlet chamber 14 are provided with two chambers, namely liquid inlet chamber 12a and liquid inlet chamber 12b, and air inlet chamber 14a and air inlet chamber 14b. Liquid inlet chamber 12a is connected to both air inlet chamber 14a and liquid inlet chamber 12b, and liquid inlet chamber 12b is also connected to air inlet chamber 14b. This allows the liquid medium entering liquid inlet chamber 12a and liquid inlet chamber 12b, and the gas medium entering air inlet chamber 14a and air inlet chamber 14b, to flow along... Figure 6 The arrows in the diagram indicate sequential mixing. However, in practical applications, in some embodiments, the positions of the liquid inlet chamber 12a and 12b, as well as the air inlet chamber 14a and 14b, can be interchanged. Furthermore, it should be noted that in this embodiment, the liquid inlet chamber 12a can be used to receive the foaming phase medium pumped out by the pumping mechanism, while the liquid inlet chamber 12b can be used to receive the non-foaming phase medium pumped out by the pumping mechanism. This allows the non-foaming phase medium to be pumped out along with the foaming phase medium after it has been mixed and foamed with the gaseous medium, resulting in a pumped-out mixture containing both the foaming and non-foaming phase media, such as makeup remover oil.

[0095] In addition, in order to better mix the foamed phase medium, the non-foamed phase medium, and the gaseous medium, such as Figure 6 As shown, the gas-liquid mixing chamber of this embodiment also includes a dispersion component 15, which includes multiple partitions 152. Each partition 152 is arranged sequentially along a predetermined direction, such that any partition 152 can directly separate two interconnected liquid inlet chambers 12 or two interconnected air inlet chambers 14. Alternatively, any partition 152 can be used to separate the interconnected liquid inlet chamber 12 and air inlet chamber 14, for example, as... Figure 6 As shown, there are three partitions 152 in total. One partition 152 separates the air inlet chamber 14a and the liquid inlet chamber 12a, another partition 152 separates the liquid inlet chamber 12a and the liquid inlet chamber 12b, and the third partition 152 separates the liquid inlet chamber 12b and the air inlet chamber 14b. Furthermore, in this embodiment, as... Figure 6 As shown, each partition 152 is also provided with a dispersion structure 151 that allows gas and liquid media to pass through. At the same time, the dispersion structure 151 can disperse the liquid media into several small particles when the liquid media passes through, so that the liquid media can be more fully mixed with the gas media.

[0096] It should be noted that, in this embodiment, as Figure 6As shown, the dispersion structure 151 consists of multiple notches 1511 on the partition plate 152. Through the notches 1511 on each partition plate 152, the foaming phase medium and the non-foaming phase medium can be dispersed into small particles, so that the foaming phase medium can achieve better foaming with the gas medium. Furthermore, since the non-foaming phase medium is also dispersed into several small particles by the notches 1511 on the partition plate 152, the non-foaming phase medium can avoid stratification with the foaming phase medium as much as possible when the foaming phase medium and the gas medium are mixed and foamed.

[0097] Example 3

[0098] The third embodiment of the present invention relates to a foaming mechanism, including a gas-liquid mixing chamber 1 as described in the first or second embodiment, wherein at least one liquid inlet chamber 12 receives a non-foaming phase medium and at least another liquid inlet chamber 12 receives a foaming phase medium.

[0099] It is easy to see from the above that the foaming mechanism 1 includes at least two liquid inlet chambers 12 and at least one air inlet chamber 14. Each liquid inlet chamber 12 is used to receive the liquid medium pumped out by the pumping mechanism. In addition, the gas-liquid mixing chamber is also used to mix the liquid medium in each liquid inlet chamber 12 and the gas medium in each air inlet chamber 14. This allows the non-foaming phase medium to be pumped out along with the foaming phase medium after mixing with the gas medium. It can also alleviate the defoaming phenomenon caused by excessively long medium transportation distance to a certain extent, and prevent the non-foaming phase medium from inhibiting the formation of foam in the foaming phase medium, and prevent the stratification phenomenon caused by the inability of the foaming phase medium and the non-foaming phase medium to dissolve.

[0100] Example 4

[0101] The fourth embodiment of the present invention relates to a foam pump, such as Figure 7 and Figure 8 As shown, it includes: a gas-liquid mixing chamber 1, a nozzle 2, and a pumping mechanism 3 as described in the first or second embodiment.

[0102] Among them, combined Figure 7 and Figure 8 As shown, the pumping mechanism 3 is used to pump liquid medium into each liquid inlet chamber 12 of the gas-liquid mixing chamber 1, and also to pump gas medium into each gas inlet chamber of the gas-liquid mixing chamber 1. In addition, the nozzle 2 is connected to the gas-liquid mixing chamber 1 and is used to spray the mixture formed after mixing and foaming in the gas-liquid mixing chamber 1.

[0103] It is easy to see from the above that the gas-liquid mixing chamber 1 includes at least two liquid inlet chambers 12 and at least one air inlet chamber 14. At least one liquid inlet chamber 12 is used to receive the liquid medium pumped out from the pumping mechanism as a non-foaming phase medium, and at least one liquid inlet chamber 12 is used to receive the liquid medium pumped out from the pumping mechanism as a foaming phase medium. In addition, the gas-liquid mixing chamber is also used to mix and foam the liquid medium in each liquid inlet chamber 12 and the gas medium in each air inlet chamber 14, and to directly pump out the mixture formed after mixing and foaming. This allows the non-foaming phase medium to be pumped out along with the foaming phase medium after mixing and foaming with the gas medium. Therefore, it can alleviate the defoaming phenomenon caused by the non-foaming phase medium inhibiting the formation of foam in the foaming phase medium due to the excessively long medium transportation distance to a certain extent, so that the medium pumped out from the nozzle can have a good foam morphology.

[0104] Example 5

[0105] The fifth embodiment of the present invention relates to a foaming method, such as... Figure 9 As shown, it includes the following steps:

[0106] Step 910: Receive the gaseous medium and at least two liquid media pumped out from the pumping mechanism. Of the received liquid media, at least one is a non-foaming phase medium, and at least one is a foaming phase medium.

[0107] Step 920: Mix and foam the liquid and gaseous media.

[0108] Step 930: Under the pressure of the pumping mechanism, the mixture formed after mixing and foaming is pumped out.

[0109] As can be seen from the above, the foaming method of this embodiment allows the non-foaming phase medium to be mixed with the foaming phase medium and the gaseous medium. This allows the non-foaming phase medium to be pumped out along with the foaming phase medium after mixing and foaming with the gaseous medium. The foam generated during the foaming of the foaming phase medium and the gaseous medium promotes the dispersion of the non-foaming phase medium, thereby effectively avoiding the phenomenon of stratification between the non-foaming phase medium and the foaming phase medium when the mixture formed by mixing and foaming is pumped out.

[0110] Furthermore, as a preferred embodiment, before receiving the liquid and gaseous media pumped out from the pumping mechanism, i.e., before step 910, the foaming method of this embodiment further includes the following steps:

[0111] Step 900: Provide a gaseous medium and at least two liquid media to the pumping mechanism. Among the liquid media provided to the pumping mechanism, at least one is a non-foaming phase medium, and at least one is a foaming phase medium. It should be noted that the gaseous and liquid media provided to the pumping mechanism can be obtained by generating negative pressure to draw them in, or they can be delivered to the pumping mechanism by applying positive pressure to them using external equipment.

[0112] It is clear from the above that this embodiment is an example of the foaming method corresponding to the third embodiment, and this embodiment can be implemented in conjunction with the third embodiment. The relevant technical details mentioned in the third embodiment remain valid in this embodiment, and will not be repeated here to avoid repetition. Correspondingly, the relevant technical details mentioned in this embodiment can also be applied to the third embodiment.

[0113] Those skilled in the art will understand that the above embodiments are specific implementations of the present invention, and in practical applications, various changes can be made in form and detail without departing from the spirit and scope of the present invention.
