Description

Technical Field

[0001] The utility model relates to the technical field of beauty instruments, in particular to a medium conveying pipeline, an atomization bin and a pneumatic atomization device. Background Art

[0002] A popular cosmetic procedure, microneedling therapy uses microneedles to stimulate the skin, creating tiny channels that allow serums to penetrate deeper into the skin. This method effectively reduces wrinkles, treats scars, whitens skin, reduces dark spots, and improves dark circles, achieving significant cosmetic results.

[0003] As the core component of the hydrating device, the atomization chamber is mainly responsible for atomizing the essence liquid. At present, the mainstream atomization chambers on the market mainly rely on high-pressure direct blowing technology. In this solution, the gas flow channel and the liquid flow channel are interconnected, and at the end, the gas and liquid share the same flow channel. The principle is to use high-speed airflow to directly collide with the liquid in the same flow channel to disperse the liquid into tiny droplets, thereby realizing the atomization of the liquid. However, this solution has obvious limitations in actual application, mainly manifested in the large size of the droplets and uneven distribution, which in turn affects the beauty effect and user experience.

[0071] Example 1

[0072] In view of the aforementioned deficiencies in the prior art, the applicant, drawing upon years of extensive practical experience and expertise in the design and manufacture of similar products, combined with the application of academic theory, has actively engaged in research and innovation, hoping to create a technology that can address these deficiencies. Through continuous research and design, and through repeated trial production and refinement, the applicant has finally created the present utility model, which possesses truly practical value.

[0073] Please refer to Figure 1-4 , the embodiment of the present utility model provides a medium conveying pipeline, including a main body 211, wherein the main body 211 is provided with a gas flow channel 22 and a liquid flow channel 23 isolated from each other;

[0074] The liquid flow channel 23 passes through one end of the main body 211 to form a liquid flow channel outlet 232;

[0075] The gas flow channel 22 passes through the opposite ends of the main body 211 to form a gas flow channel outlet 221 and a gas flow channel inlet 222 respectively;

[0076] The gas flow channel outlet 221 and the liquid flow channel outlet 232 are disposed at the same end of the main body 211 .

[0077] It should be noted that this embodiment optimizes the flow channel design based on the principle of negative pressure aspiration atomization, thereby significantly improving the atomization effect and stability. Specifically, a mutually isolated gas flow channel 22 and liquid flow channel 23 are provided in the main body 211 of the medium delivery pipeline, which can achieve simultaneous independent delivery of two media. This design ensures that the gas and liquid are independent of each other during the atomization process. They only combine with each other at the liquid flow channel outlet 232, making it easier to control the liquid output and thus facilitate the adjustment of the mist output effect, ensuring the uniformity and stability of the atomization.

[0078] The liquid channel outlet 232 is used to guide the essence out of the liquid channel 23. A gas channel inlet 222 is provided at one end of the gas channel 22 for introducing external gas, and a gas channel outlet 221 is provided at the other end. The gas channel outlet 221 and the liquid channel outlet 232 are arranged at the same end of the main body 211, so that the liquid and gas are respectively guided to the same end of the main body 211 to achieve uniform and stable atomization.

[0079] In addition, since this medium conveying pipeline integrates the gas flow channel 22 and the liquid flow channel 23, it not only facilitates product assembly, but also reduces production costs, and can be used as a separate supply material.

[0080] Please refer again Figure 1-3 In this embodiment, further, the main body 211 is further provided with a liquid inlet 28 connected to the liquid flow channel 23, and the liquid inlet 28 is provided at one end of the main body 211 away from the liquid flow channel outlet 232.

[0081] It should be noted that the liquid inlet 28 can be used as an inlet for replenishing the essence, so as to facilitate replenishing the essence into the liquid flow channel 23. After replenishment, the liquid inlet 28 can be sealed to ensure that no leakage occurs.

[0082] Please refer again Figure 2-3 , in this embodiment, further, the medium delivery pipeline further includes a sealing member 32;

[0083] At least two sealing members 32 are provided, which are respectively sleeved on the outer wall of the main body 211 and spaced apart, and the liquid inlet 28 is located between the two sealing members 32; or,

[0084] At least one sealing member 32 is provided, and the sealing member 32 is sleeved on the outer peripheral side of the liquid inlet 28 .

[0085] It should be noted that the seal 32 is provided to ensure the sealing between the medium delivery pipe and the beauty instrument after it is installed, and to prevent the essence from leaking from the gap between the liquid inlet 28 and the beauty instrument. According to the description of this embodiment, there are at least two possible settings:

[0086] In a first possible configuration, two spaced-apart sealing members 32 are provided between the outer wall of the main body 211 and the wall of the beauty instrument, and the liquid inlet 28 is located between the two sealing members 32. This design prevents the essence from leaking outwards due to the obstruction of the two sealing members 32.

[0087] In a second possible arrangement, the sealing member 32 is sleeved on the outer peripheral side of the liquid inlet 28. Although this design only provides one sealing point, since the liquid inlet 28 is a key position, this arrangement can still effectively prevent liquid leakage.

[0088] Please refer again Figure 4 , in this embodiment, the liquid flow channel 23 includes a liquid sub-flow channel 231;

[0089] The liquid sub-channel 231 is arranged in a straight line;

[0090] Or, the liquid flow channel 23 includes at least two liquid sub-flow channels 231;

[0091] The plurality of liquid sub-channels 231 are connected end to end in sequence to form a tortuous shape.

[0092] It should be noted that the term "tortuous" refers to the design of the liquid flow channel 23 being non-linear, but rather having multiple bends, turns, or curves. Compared to a liquid flow channel 23 extending straight from the liquid inlet 28 to the liquid flow channel outlet 232, i.e., a liquid flow channel 23 comprising a straight liquid sub-flow channel 231, a tortuous design can increase the length and area of the liquid flow channel 23, thereby increasing the storage capacity of the essence, thereby extending the service life of the medium delivery pipeline and reducing the frequency of medium delivery pipeline replacement or fluid replenishment.

[0093] like Figure 4 As shown, the essence will flow from port a at one end of a liquid sub-channel 231 to port b at the other end, then from port b to port c at one end of another liquid sub-channel 231, and then from port c through the liquid sub-channel 231 to the other end of the liquid sub-channel 231, and so on.

[0094] Although the terms "medium conveying pipeline," "gas flow channel," "liquid flow channel," "liquid outlet," and "gas inlet" are frequently used in this application, the use of other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.

[0095] The utility model provides a medium conveying pipeline, which optimizes the flow channel design based on the principle of negative pressure suction atomization, that is, the gas flow channel and the liquid flow channel are isolated from each other, so that when the gas is ejected from the outlet of the gas flow channel, a negative pressure area is formed at the outlet of the liquid flow channel, thereby effectively sucking the liquid out from the liquid outlet and making the liquid quickly atomized after combining with the gas. Not only is the size of the droplets small enough, but the distribution is also uniform, which is beneficial to improving the beauty effect and user experience.

[0096] Example 2

[0097] Please refer to Figure 5-13 The embodiment of the present invention provides an atomization chamber, comprising an atomization nozzle 20 and a medium delivery pipe 21, the atomization nozzle 20 comprises a liquid outlet 24 and a gas outlet 26, and the medium delivery pipe 21 is provided with a gas flow channel 22 and a liquid flow channel 23 isolated from each other;

[0098] The liquid outlet 24 is communicated with the liquid flow channel 23 , and the gas outlet 26 is communicated with the gas flow channel 22 .

[0099] It is understandable that the atomizing nozzle 20 can be designed as an independent component, or can be designed as a part of the medium delivery pipeline 21 and designed as an integral part with the medium delivery pipeline 21. The specific selection can be made according to product design requirements.

[0100] It should be noted that this embodiment optimizes the flow channel design based on the principle of negative pressure aspiration atomization, thereby significantly improving the atomization effect and stability. Specifically, the atomization chamber is provided with a mutually isolated gas flow channel 22 and liquid flow channel 23 within the medium delivery pipeline 21. This design ensures that the gas and liquid only combine at the liquid outlet 24 during the atomization process, thereby ensuring the uniformity and stability of the atomization.

[0101] At one end of the liquid channel 23 is a liquid outlet 24 for discharging the essence from the liquid channel 23. At one end of the gas channel 22 is an air inlet 25 for introducing external air, and at the other end is an air outlet 26, located near the liquid outlet 24. When gas enters the gas channel 22 from the air inlet 25 and is ejected at high speed through the air outlet 26, a negative pressure region is formed at the liquid outlet 24. This negative pressure effect allows the liquid to be quickly drawn out of the liquid outlet 24, where it is rapidly atomized after combining with the high-speed ejected gas.

[0102] This negative pressure atomization principle not only makes the droplets small enough, but also more evenly distributed. Small droplets can better penetrate deep into the skin, while the even distribution ensures that the essence can act evenly on the skin, thereby enhancing the beauty effect.

[0103] In addition, it is understandable that compared with essence in liquid form, essence in aerosol form can better penetrate into the skin and be absorbed by the skin, and it can also better control the amount sprayed each time and the uniformity of the spraying, so it is not easy to cause waste.

[0104] Please refer again Figure 5-7In the present embodiment, further, the atomizing nozzle 20 includes a liquid outlet part 201 and a socket part 202, the socket part 202 is sleeved on the outer peripheral side of the liquid outlet part 201, the liquid outlet 24 passes through the liquid outlet part 201, and an air outlet cavity 203 is provided between the socket part 202 and the liquid outlet part 201, the air outlet cavity 203 is communicated with the gas flow channel 22, and the air outlet 26 is formed at one end of the air outlet cavity 203 away from the gas flow channel 22. It should be noted that the design of the air outlet cavity 203 is more conducive to uniform airflow at the air outlet 26. It is understandable that the air outlet 26 and the liquid outlet 24 can also be directly formed on the main body 211. In this case, the liquid flow channel outlet 232 is the liquid outlet 24, and the gas flow channel outlet 221 is the air outlet 26, so that more convenient production and assembly can be achieved.

[0105] Please refer again Figure 5-7 In this embodiment, further, the gas outlet 26 is arranged around part or all of the liquid outlet 24, such as Figure 6 As shown;

[0106] Alternatively, the gas outlet 26 and the liquid outlet 24 are arranged side by side;

[0107] Alternatively, the liquid outlet 24 is disposed around part or all of the liquid outlet 24. The air outlet 26 being disposed side by side with the liquid outlet 24 should be understood to mean that there is only one air outlet 26 disposed side by side with the liquid outlet 24. The air outlet 26 being disposed around part or all of the liquid outlet 24 should be understood to mean that there are multiple air outlets 26 disposed along the outer periphery of the liquid outlet 24.

[0108] It should be noted that in the design of the beauty instrument, the positional relationship between the air outlet 26 and the liquid outlet 24 is an important factor affecting the atomization effect of liquids such as essences. The air outlet 26 is arranged around part or all of the liquid outlet 24 to achieve a uniform and soft atomization effect. The air outlet 26 and the liquid outlet 24 are arranged side by side. Because the air outlet is relatively concentrated, under the same output power of the air supply mechanism, the gas flow rate is faster than that of the annular air outlet 26, which can increase the atomization speed. The liquid outlet 24 is arranged around part or all of the air outlet 26, so that the atomization area and atomization flow rate can be expanded as much as possible while ensuring a high atomization speed.

[0109] Specifically, when the gas outlet 26 surrounds part or all of the liquid outlet 24, the gas surrounds the essence, creating a "gas surround" effect, allowing the essence to be more evenly encapsulated and atomized. This approach ensures that the essence is fully atomized, thereby improving its permeability and utilization rate. Furthermore, due to the gas surround effect, the essence atomization process is gentler and less irritating to the skin.

[0110] When the gas outlet 26 and the liquid outlet 24 are arranged side by side, this positional relationship can make the mixing of the essence and the gas more direct and rapid, thereby increasing the speed of atomization.

[0111] When the liquid outlet 24 is arranged around part or all of the gas outlet 26, the essence can flow toward the gas outlet 26 from multiple directions, increasing the amount of essence flowing out per unit time and increasing the contact area between the essence and the gas. This design not only ensures that more essence flows out and is fully atomized, but also achieves a uniform atomization effect over a wider area.

[0112] In the actual production process, the appropriate layout can be selected according to specific needs and product characteristics to achieve the best atomization effect.

[0113] In this embodiment, the distance between the liquid outlet 24 and the gas outlet 26, and / or the ratio of their areas, must meet certain misting conditions, which affect the misting effect. By properly designing these two parameters, the misting device can ensure that it can produce a uniform and delicate atomization effect, thereby improving the skin care effect and user experience.

[0114] Specifically, the distance between the liquid outlet 24 and the air outlet 26 can be set within a range greater than 0 mm and less than or equal to 0.5 mm. For example, the distance between the liquid outlet 24 and the air outlet 26 can be 0.01 mm, 0.25 mm or 0.5 mm. Optionally, the distance between the liquid outlet 24 and the air outlet 26 can be set based on the desired misting effect. For example, when the desired misting amount is larger and finer, the distance between the liquid outlet 24 and the air outlet 26 can be set to 0.01 mm; when the desired misting effect is medium, the distance between the liquid outlet 24 and the air outlet 26 can be set to 0.25 mm; when the desired misting amount is smaller and the atomized particles are larger, the distance between the liquid outlet 24 and the air outlet 26 can be set to 0.5 mm.

[0115] It's important to note that this spacing determines the contact method and speed between the serum and the gas. If the spacing is too large, the serum and gas may not fully contact and mix, resulting in poor atomization. If the spacing is too small, the serum and gas may mix too quickly, also affecting atomization. Therefore, this spacing range is designed to ensure that the serum and gas mix at the appropriate speed and distance for efficient atomization.

[0116] The area ratio of the liquid outlet 24 to the gas outlet 26 can be set within the range of 0.2-0.7.

[0117] It should be noted that this area ratio range means that the ratio of the area of the liquid outlet 24 to the area of the gas outlet 26 should be maintained within this ratio range. This ratio determines the degree of mixing of the essence and the gas. For example, the area ratio of the liquid outlet 24 to the gas outlet 26 can be set to 0.2, 0.45 or 0.70. Optionally, the area ratio of the liquid outlet 24 to the gas outlet 26 can be set based on the required misting effect. For example, when the required misting amount is small and the mist is finer, the area ratio of the liquid outlet 24 to the gas outlet 26 can be set to 0.2; when the required misting effect is medium, the area ratio of the liquid outlet 24 to the gas outlet 26 can be set to 0.45; when the required misting amount is large and the atomized particles are large, the area ratio of the liquid outlet 24 to the gas outlet 26 can be set to 0.70. If the area ratio is too small (e.g., less than 0.2), the liquid outlet 24 may be too little, resulting in a small and uneven mist output. If the area ratio is too large (e.g., greater than 0.7), the liquid may be too much, and the gas output from the gas outlet 26 may be relatively small, which may result in insufficient atomization of the liquid or even the formation of droplets. Therefore, this ratio range is intended to ensure that the liquid and gas are evenly and thoroughly mixed, thereby producing an ideal atomization effect.

[0118] Please refer again Figure 5 In this embodiment, further, the liquid outlet 24 is relatively protruding from the gas outlet 26 .

[0119] It should be noted that, since the negative pressure zone will be formed at a certain distance from the air outlet 26, that is, the negative pressure zone will be in front of the air outlet 26, the liquid outlet 24 needs to be designed to be slightly protruding relative to the air outlet 26, so that the liquid outlet 24 can be closer to the negative pressure zone, which is more conducive to mist discharge.

[0120] In this embodiment, the design of the beauty instrument is further expanded and improved.

[0121] Please refer again Figure 5-7 , and combined with reference Figure 12 In the first embodiment, the atomization chamber further includes a liquid storage chamber 27, which is used to store the essence;

[0122] The end of the liquid flow channel 23 away from the liquid outlet 24 is provided with a liquid inlet 28, and the liquid inlet 28 is connected to the liquid storage tank 27. Figure 12 shown.

[0123] It should be noted that, by setting up a liquid storage tank 27 in the atomization tank, this embodiment can provide a certain storage space for the essence, increase the storage capacity of the essence in the atomization tank, thereby increasing the service life of the atomization tank and reducing the frequency of changing the atomization tank or replenishing the liquid.

[0124] In addition, the liquid storage tank 27 and the atomization tank can be designed as an integral whole and cannot be disassembled, which improves the integrity of the structure, avoids errors caused by human assembly, and reduces the risk of leakage.

[0125] It is understandable that if the atomization chamber is designed for liquid replenishment, then in order to facilitate the replenishment of essence into the liquid storage chamber 27, a liquid replenishment port connected to the liquid storage chamber 27 is also opened on the atomization chamber.

[0126] Please refer again Figure 5-7 and 13. In this embodiment, further, the gas flow channel 304 surrounds part or all of the liquid flow channel 23;

[0127] The liquid storage tank 27 surrounds part or all of the liquid flow channel 23 .

[0128] It should be noted that, in order to increase the reliability of use and ensure the atomization effect, the gas flow channel 304 needs to ensure the gas output volume and gas output speed, and the gas flow channel 304 needs to be arranged around the liquid flow channel 23. On the one hand, it can surround part of the liquid flow channel 23, and on the other hand, it can surround the entire liquid flow channel 23. Figure 13 As shown, this design can increase the cross-sectional area of the gas flow channel 304 and the total ventilation volume, thereby increasing the flow rate at the gas outlet 26 and increasing the negative pressure of the environment near the gas outlet 26 to ensure the atomization effect.

[0129] Figure 5-7 The figure shows the case where the gas flow channel 304 surrounds part of the liquid flow channel 23. In this case, one gas flow channel 304 can be set to surround part of the liquid flow channel 23, or at least two gas flow channels 304 can be set to surround part of the liquid flow channel 23. The number and shape of the gas flow channels 304 can be specifically set according to actual needs. Figure 5-7 In the embodiment, the number of the gas flow channels 304 is set to two, the shape of the gas flow channels 304 is crescent-shaped, and the gas flow channels 304 are symmetrically arranged.

[0130] It should also be noted that, in order to increase the storage capacity of the essence and ensure that it can be used for a longer period of time, the liquid storage tank 27 can be arranged to surround part of the liquid flow channel 23, or the liquid storage tank 27 can be arranged to surround the entire liquid flow channel 23. The liquid storage tank 27 surrounding the entire liquid flow channel 23 can obtain a larger liquid storage space.

[0131] Please refer again Figure 5-7 In the second embodiment, the other end of the liquid flow channel 23 is closed from the liquid outlet 24, and the liquid flow channel 23 is used to store the essence.

[0132] It is understandable that the difference between the second embodiment and the first embodiment is that the second embodiment does not provide a liquid storage tank 27 specifically for storing the essence, but directly stores the essence in the liquid flow channel 23.

[0133] It should be noted that the closed end of the liquid flow channel 23 can be a design without a liquid inlet 28, which corresponds to a non-liquid replenishment design, or it can be a design with a liquid inlet 28 but the liquid inlet 28 can be blocked, which corresponds to a liquid replenishment design.

[0134] Specifically, if the design is for liquid replenishment, the liquid inlet 28 of the liquid flow channel 23 can be used as the entrance for liquid replenishment, so as to facilitate the replenishment of essence in the liquid flow channel 23. After replenishment, the liquid inlet 28 of the liquid flow channel 23 can be sealed by the sealing plug 31 to ensure that no leakage occurs. Figure 10 shown.

[0135] Please refer again Figure 9 and Figure 11 , in this embodiment, further, the liquid flow channel 23 includes a liquid sub-flow channel 231;

[0136] The liquid sub-channel 231 is arranged in a straight line;

[0137] Or, the liquid flow channel 23 includes at least two liquid sub-flow channels 231;

[0138] The plurality of liquid sub-channels 231 are connected end to end in sequence to form a tortuous shape.

[0139] It should be noted that the term "tortuous" refers to the design of the liquid flow channel 23 being non-linear, but rather having multiple bends, turns, or curves. Compared to a liquid flow channel 23 extending straight from the liquid inlet 28 to the liquid outlet 24, i.e., a liquid flow channel 23 comprising a straight liquid sub-flow channel 231, a tortuous design can increase the length and area of the liquid flow channel 23, thereby increasing the storage capacity of the essence, thereby extending the service life of the medium delivery pipeline and reducing the frequency of medium delivery pipeline replacement or fluid replenishment.

[0140] like Figure 9 As shown, the essence will flow from port a at one end of a liquid sub-channel 231 to port b at the other end, then from port b to port c at one end of another liquid sub-channel 231, and then from port c through the liquid sub-channel 231 to the other end of the liquid sub-channel 231, and so on.

[0141] Please refer again Figure 5 In this embodiment, further, if a liquid storage tank 27 is designed, the liquid storage tank 27 is provided with an air pressure regulating hole 29 , and the air pressure regulating hole 29 is provided with an air-permeable liquid-blocking member 30 .

[0142] If the liquid storage tank 27 is not designed, the liquid flow channel 23 is provided with an air pressure regulating hole 29 , and the air pressure regulating hole 29 is provided with an air-permeable and liquid-blocking member 30 .

[0143] It should be noted that the purpose of providing the air pressure regulating hole 29 in both the liquid reservoir 27 and the liquid flow channel 23 is to regulate the internal air pressure. During operation of the beauty device, the air pressure within the liquid reservoir 27 or the liquid flow channel 23 may decrease due to the consumption of the essence, thereby affecting the supply of essence. To maintain stable air pressure, a method is required to balance the internal and external pressure differences, and the air pressure regulating hole 29 fulfills this role.

[0144] Specifically, the air pressure regulating hole 29 can be located away from the lowest level of the essence. Furthermore, the air-permeable liquid barrier 30 provided in the air pressure regulating hole 29 allows air to pass through while preventing the essence from leaking. Specifically, the air-permeable liquid barrier 30 can be made of a material that is air-permeable but liquid-impermeable, such as a special porous material or film. This allows air to flow freely through the air pressure regulating hole 29, thereby balancing the air pressure inside and outside the liquid reservoir 27 or liquid flow channel 23. The essence, however, is blocked by the air-permeable liquid barrier 30 and prevents it from leaking out of the air pressure regulating hole 29.

[0145] The design of the air pressure regulating hole 29 and the air-permeable liquid-blocking member 30 achieves stable air pressure within the liquid reservoir 27 or liquid flow channel 23, while also preventing accidental leakage of the essence. This not only enhances the stability and safety of the beauty device, but also provides users with a more comfortable and secure skincare experience.

[0146] Please refer again Figure 5 In this embodiment, further, the liquid inlet 28 is opened at a position corresponding to the bottom position of the liquid storage tank 27.

[0147] It should be noted that, as mentioned above, the structural design of the first shell 101 conforms to ergonomics, that is, when the user uses the mesotherapy beauty instrument, the mesotherapy beauty head 3 is tilted, and the lowest liquid level of the essence in the liquid storage tank 27 will be located at the bottom of the liquid storage tank 27. At this time, the liquid inlet 28 opened at the bottom position of the corresponding liquid storage tank 27 can more easily discharge the essence concentrated at the bottom position of the liquid storage tank 27, reduce the residual essence in the liquid storage tank 27, improve the utilization rate of the essence, and thus reduce waste.

[0148] In addition, the medium delivery pipe 21 may have an anti-fool-proof installation design. Through the anti-fool-proof design, it can be ensured that the medium delivery pipe 21 is correctly installed on the beauty instrument, so that the liquid inlet 28 is set towards the lowest liquid level of the essence.

[0149] The utility model provides an atomization chamber, which optimizes the flow channel design based on the principle of negative pressure suction atomization, that is, the gas flow channel and the liquid flow channel are isolated from each other, so that when the gas is ejected from the gas outlet, a negative pressure area will be formed at the liquid outlet, thereby effectively sucking the liquid out of the liquid outlet and making the liquid quickly atomized after combining with the gas. Not only is the size of the droplets small enough, but the distribution is also uniform, which is beneficial to improving the beauty effect.

[0150] Example 3

[0151] Please refer to Figure 14 , the embodiment of the present utility model provides a pneumatic atomization device, comprising an air supply mechanism 1 and an atomization bin 2 as provided in the above embodiment 1;

[0152] The atomization chamber 2 is communicated with the air supply mechanism 1 .

[0153] It should be noted that the gas provided by the gas supply mechanism 1 is delivered to the gas flow channel 22 through the gas inlet 25 .

[0154] Illustratively, the gas supply mechanism 1 may be a small air pump or a compressed gas storage device, which can provide gas with sufficient pressure and flow to the atomization chamber 2 when needed.

[0155] It is understandable that, if assembled to a product, the atomization chamber 2 can be provided in the third shell 3 , and the air supply mechanism 1 can be provided in the first shell 4 .

[0156] The utility model provides a pneumatic atomizing device, which optimizes the flow channel design based on the principle of negative pressure suction atomization, that is, the gas flow channel and the liquid flow channel are isolated from each other, so that when the gas is ejected from the gas outlet, a negative pressure area is formed at the liquid outlet, thereby effectively sucking the liquid out of the liquid outlet and making the liquid quickly atomized after combining with the gas. Not only is the size of the droplets small enough, but the distribution is also uniform, which is beneficial to improving the beauty effect.

[0157] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application.
