[0060] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0061] Embodiment 1

[0062] In view of the defects of the above-mentioned prior art, the applicant, based on many years of rich practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of theory, actively conducts research and innovation in the hope of creating a technology that can solve the defects of the prior art. After continuous research and design, and after repeated trial samples and improvements, the present utility model with real practical value was finally created.

[0063] Please refer to Figure 1-8 The present utility model embodiment provides a pneumatic atomization device, including an air supply mechanism 401 and an atomization mechanism 402; wherein,

[0064] The atomizing mechanism 402 includes an atomizing chamber 4021, and a gas flow channel 4026 and a liquid flow channel 4027 are provided in the atomizing chamber 4021;

[0065] A liquid outlet 4025 is provided at one end of the liquid flow channel 4027;

[0066] An air inlet 4022 is provided at one end of the gas flow channel 4026, and an air outlet 4023 is provided at the other end;

[0067] The air inlet 4022 is communicated with the air supply mechanism 401 , and the air outlet 4023 is disposed close to the liquid outlet 4025 .

[0068] It should be noted that, compared with essence in liquid form, essence in aerosol form can better penetrate into the skin and be absorbed by the skin, and can also better control the amount of each spray and the uniformity of spraying, so it is not easy to cause waste, so it is necessary to atomize the essence before it reaches the facial skin of the human body. This embodiment is based on the principle of gas path atomization, by providing high-speed gas through the gas supply mechanism 401, and then conveying the high-speed gas to the gas flow channel 4026, so as to use the high-speed gas to form a negative pressure at the gas outlet 4023, which can drive the essence in the liquid flow channel 4027 to spray out from the liquid outlet 4025, and make the sprayed essence become small molecule aerosol after combining with the high-speed gas surrounding it, so as to realize the atomization of the essence.

[0069] Exemplarily, the gas supply mechanism 401 may be a small air pump or a compressed gas storage device, which can provide gas with sufficient pressure and flow to the atomization mechanism 4026 when needed.

[0070] In this embodiment, further, the gas outlet 4023 may be arranged around part or all of the liquid outlet 4025, such as Figure 3 or, the gas outlet 4023 and the liquid outlet 4025 may be arranged side by side, or, the liquid outlet 4025 may be arranged around part or all of the gas outlet 4023. It is understandable that the gas outlet 4023 may be arranged around part or all of the liquid outlet 4025, including the case where a plurality of gas outlets 4023 are provided and arranged along the circumference of the liquid outlet 4025.

[0071] In the design of the beauty instrument, the positional relationship between the air outlet 4023 and the liquid outlet 4025 is an important factor affecting the atomization effect of the essence. The air outlet 4023 is arranged around part or all of the liquid outlet 4025 to achieve a uniform and soft atomization effect. The air outlet 4023 and the liquid outlet 4025 are arranged side by side (that is, only one air outlet 4023 is arranged around the liquid outlet 4025). Because the air outlet is relatively concentrated, under the same output power of the air supply mechanism 8, the gas flow rate is faster than that of the annularly arranged air outlet 4023, which can increase the atomization speed. The liquid outlet 4025 is arranged around part or all of the air outlet 4023, so that the atomization area and the atomization flow rate can be expanded as much as possible while ensuring a high atomization speed.

[0072] Specifically, when the gas outlet 4023 is arranged around part or all of the liquid outlet 4025, the gas surrounds the essence, forming a "gas surround" effect, so that the essence is more evenly wrapped and atomized by the gas. This method can ensure that the essence is fully atomized, thereby improving its permeability and utilization rate. At the same time, due to the effect of gas surround, the atomization process of the essence is gentler and less irritating to the skin.

[0073] When the gas outlet 4023 and the liquid outlet 4025 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.

[0074] When the liquid outlet 4025 is arranged around part or all of the gas outlet 4023, the essence can flow to the gas outlet 4023 from multiple directions, increasing the outflow of the essence per unit time and increasing the contact area between the essence and the gas. Such a design can not only ensure that more essence flows out and is fully atomized, but also achieve a uniform atomization effect over a wider area.

[0075] In the actual production process, the appropriate layout can be selected according to specific needs and product characteristics to achieve better atomization effect.

[0076] In this embodiment, further, the distance between the liquid outlet 4025 and the gas outlet 4023, and / or the range of their area ratio needs to meet certain conditions to achieve a better misting effect. By reasonably designing these two parameters, it can be ensured that the misting device can produce a uniform and delicate atomization effect, thereby improving the skin care effect and user experience.

[0077] Specifically, the distance between the liquid outlet 4025 and the gas outlet 4023 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 4025 and the gas outlet 4023 can be 0.01 mm, 0.25 mm or 0.5 mm. Optionally, the distance between the liquid outlet 4025 and the gas outlet 4023 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 4025 and the gas outlet 4023 can be set to 0.01 mm; when the desired misting effect is medium, the distance between the liquid outlet 4025 and the gas outlet 4023 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 4025 and the gas outlet 4023 can be set to 0.5 mm.

[0078] It should be noted that this spacing determines the contact mode and speed of the essence and gas. If the spacing is too large, the essence and gas may not be able to fully contact and mix, resulting in poor atomization effect. Therefore, this spacing range is to ensure that the essence and gas can mix at an appropriate speed and distance, thereby achieving efficient atomization.

[0079] The area ratio of the liquid outlet 4025 to the gas outlet 4023 may be set within a range of 0.2-0.7.

[0080] It should be noted that this area ratio range means that the ratio between the area of ​​the liquid outlet 4025 and the area of ​​the gas outlet 4023 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 4025 to the gas outlet 4023 can be set to 0.2, 0.45 or 0.70. Optionally, the area ratio of the liquid outlet 4025 to the gas outlet 4023 can be set based on the desired misting effect. For example, when the required misting amount is small and the mist is fine, the area ratio of the liquid outlet 4025 to the gas outlet 4023 can be set to 0.2; when the required misting effect is medium, the area ratio of the liquid outlet 4025 to the gas outlet 4023 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 4025 to the gas outlet 4023 can be set to 0.70. If the area ratio is too small (e.g., less than 0.2), the essence liquid at the liquid outlet 4025 may be too little, resulting in too little mist output and uneven atomization; if the area ratio is too large (e.g., greater than 0.7), the essence liquid may be too much, and the gas output at the gas outlet 4023 may be relatively small, which may also cause the essence liquid to be unable to be fully atomized or even produce droplets. Therefore, this ratio range is to ensure that the essence liquid and the gas can be evenly and fully mixed, thereby producing an ideal atomization effect.

[0081] Please refer again Figure 2 In the first implementation of the present embodiment, the atomization mechanism 402 further includes a liquid storage tank 4028, a liquid inlet 4024 is provided at the other end of the liquid flow channel 4027, and the liquid storage tank 4028 stores essence liquid;

[0082] The liquid inlet 4024 is connected to the liquid storage tank 4028. Fig. 9 shown.

[0083] It should be noted that, by providing the liquid storage tank 4028, this embodiment can provide a certain storage space for the essence, thereby increasing the storage capacity of the essence, thereby increasing the use time of the pneumatic atomization device and reducing the frequency of replacing the device or replenishing the liquid.

[0084] In addition, the liquid storage tank 4028 and the atomization tank 4021 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.

[0085] It is understandable that if the pneumatic atomization device is designed for liquid replenishment, then in order to facilitate the replenishment of essence liquid in the liquid storage tank 4028, the atomization tank 4021 device is also provided with a liquid replenishment port connected to the liquid storage tank 4028.

[0086] Please refer again Figure 2-4 In this embodiment, the gas flow channel 4026 is arranged close to the liquid flow channel 4027; for example, the gas flow channel 4026 surrounds part or all of the liquid flow channel 4027, or the gas flow channel 4026 and the liquid flow channel 4027 are arranged side by side.

[0087] The liquid storage tank 4028 surrounds part or all of the liquid flow channel 4027.

[0088] It should be noted that, in order to increase the reliability of use and ensure the atomization effect, the gas flow channel 4026 needs to ensure the gas output volume and gas output speed. In this embodiment, the gas flow channel 4026 can be optionally arranged around the liquid flow channel 4027. On the one hand, it can be around part of the liquid flow channel 4027, and on the other hand, it can also be around the entire liquid flow channel 4027. Fig.10 This design can increase the cross-sectional area and the total ventilation volume, thereby increasing the flow rate at the air outlet 4023 and increasing the negative pressure of the environment near the air outlet 4023 to ensure the atomization effect.

[0089] Figure 2-4 The figure shows the case where the gas flow channel 4026 surrounds part of the liquid flow channel 4027. In this case, one gas flow channel 4026 may be arranged to surround part of the liquid flow channel 4027, or at least two gas flow channels 4026 may be arranged to surround part of the liquid flow channel 4027. The number and shape of the gas flow channels 4026 may be specifically set according to actual needs. Figure 2-4 In the figure, the number of gas flow channels 4026 is set to two, the shape is crescent-shaped, and they are symmetrically arranged.

[0090] It should 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, on the one hand, the liquid storage tank 4028 can surround part of the liquid flow channel 4027, and on the other hand, the liquid storage tank 4028 can surround the entire liquid flow channel 4027. The liquid storage tank 4028 can be arranged around the entire liquid flow channel 4027.

[0091] Please refer again Figure 5-8In the second implementation of this embodiment, the other end of the liquid flow channel 4027 is closed, and essence is stored in the liquid flow channel 4027. For example, the liquid inlet 4024 can be provided with a sealing plug 4029.

[0092] It can be understood that, in this embodiment, the second embodiment differs from the first embodiment only in that the second embodiment does not have a liquid storage tank 4028 specifically used for storing essence, but directly stores the essence in the liquid flow channel 4027. As for the structural design between the liquid flow channel and the gas flow channel, and between the liquid storage tank and the liquid flow channel, the considerations of the two may be the same or different.

[0093] It should be noted that if the pneumatic atomization device is designed for liquid replenishment, the liquid inlet 4024 can be used as the entrance for liquid replenishment, so as to facilitate the replenishment of essence liquid in the liquid flow channel 4027. After replenishment, the sealing plug 4029 seals the liquid inlet 4024 to ensure that no leakage occurs.

[0094] Please refer again Figure 6 and Figure 8 In this embodiment, the liquid flow channel 4027 includes a plurality of liquid sub-flow channels 40271, and the plurality of liquid sub-flow channels 40271 are sequentially connected end to end to form a tortuous shape.

[0095] It should be noted that the tortuous shape means that the design of the liquid flow channel 4027 is not a straight line, but has multiple bends, turns or curves. Compared with the liquid flow channel 4027 extending straight from the liquid inlet 4024 to the liquid outlet 4025, the tortuous design can increase the length and area of ​​the liquid flow channel 4027, which is conducive to increasing the storage capacity of the essence, thereby increasing the use time of the pneumatic atomization device and reducing the frequency of changing the beauty head or replenishing the liquid.

[0096] like Figure 6 As shown, the essence will flow from port a at one end of a liquid sub-channel 40271 to port b at the other end, then from port b to port c at one end of another liquid sub-channel 40271, and then from port c through the liquid sub-channel 40271 to the other end of the liquid sub-channel 40271, and so on. Compared with the liquid sub-channel 40271 extending straight from the liquid inlet 4024 of the liquid sub-channel 40271 to the liquid outlet 4025 of the liquid sub-channel 40271, the tortuous design can increase the length and accommodation space of the liquid sub-channel 40271, which is conducive to increasing the storage capacity of the essence, thereby increasing the use time of the pneumatic atomization device and reducing the frequency of replacing the device or replenishing the liquid.

[0097] Although the terms such as air supply mechanism, atomization mechanism, atomization chamber, air inlet, air outlet, etc. are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.

[0098] The utility model provides a pneumatic atomization device. Since the gas provided by the gas supply mechanism will form a negative pressure at the gas outlet through the gas flow channel, it can drive the essence in the liquid flow channel to spray out from the liquid outlet, and the sprayed essence is turned into small molecule mist after combining with the gas surrounding it, thereby realizing the atomization of the essence. Compared with the essence in liquid form, the essence in the mist form can not only better penetrate into the skin and be absorbed by the skin, but also can better control the amount sprayed each time and the uniformity of the spraying, so it is not easy to cause waste, thereby improving the user experience.

[0099] Embodiment 2

[0100] Please refer to Figure 11-14 The present utility model embodiment provides a water light instrument, comprising a housing 1, a microneedle device 2, a control mechanism 3 and a pneumatic atomization device 4 as in the above-mentioned embodiment 1;

[0101] The microneedle device 2 is arranged on the housing 1;

[0102] The pneumatic atomizing device 4 is arranged in the housing 1, and the air supply mechanism 401 is electrically connected to the control mechanism 3;

[0103] The shell 1 is provided with an atomization outlet 5 , which is in communication with the liquid outlet 4025 and the gas outlet 4023 .

[0104] It should be noted that the microneedle device 2 can stimulate the skin after contacting the skin, forming fine skin channels on the skin surface so as to allow the essence to penetrate into the skin to achieve a cosmetic effect. Optionally, the microneedle device 2 can be a nano-microneedle wafer or other forms of microneedles.

[0105] Please refer again Figure 11-12 and Fig.14 The microneedle device 2 is located in front of the atomization outlet 5 in the mist outlet direction, and a avoidance hole 6 is opened in the microneedle device 2 corresponding to the position of the atomization outlet 5; and / or, the microneedle device 2 and the atomization outlet 5 are arranged side by side.

[0106] It should be noted that, since the microneedle device 2 contacts the skin and stimulates the skin through the microneedles thereon, a fine skin channel is formed on the skin surface, and the atomized essence is sprayed on the facial skin and penetrates into the skin through the skin channel. Therefore, in order to promote the absorption of the atomized essence and improve the skin care effect, the area where the microneedle device 2 is located can cover the area where the atomization outlet 5 is located, and an avoidance hole 6 is opened at the position of the microneedle device 2 corresponding to the atomization outlet 5, so that the atomized essence can be sprayed from the atomization outlet 5 and the avoidance hole 6 in turn, and finally reach the skin stimulated by the microneedle device 2. Of course, the microneedle device 2 can also be arranged side by side with the atomization outlet 5. Specifically, it includes that the microneedle device 2 is close to the atomization outlet 5 and arranged in parallel with it. When the microneedle device 2 is arranged in the housing 1, a gap is formed between the microneedle device 2 and the housing 1, and the essence atomized through the liquid outlet 4025 can overflow from the peripheral side of the microneedle device 2, that is, the peripheral side of the microneedle device 2 forms the atomization outlet 5. The microneedle device 2 and the atomization outlet 5 are arranged side by side, which should also include the case where the atomization outlet 5 is arranged on the peripheral side of the microneedle device 2. The peripheral side misting method can make the mist disperse more evenly and faster, and improve the uniformity of the mist adhering to the skin. Of course, on this basis, the avoidance hole 6 can also be opened in the microneedle device 2 at the same time. At this time, the avoidance hole 6 can also be used as a part of the atomization outlet 5, so as to increase the mist outlet area and increase the mist outlet amount, and at the same time, the mist sprayed on the skin can be more uniform.

[0107] Optionally, the avoidance hole 6 is opened at the center of the microneedle device 2, and the avoidance hole 6 is coaxially arranged with the atomization outlet 5 to ensure that the skin area stimulated once by the microneedle device 2 can evenly absorb the atomized essence.

[0108] Please refer again Fig.11 In this embodiment, the water light instrument further includes a driving mechanism 7;

[0109] The housing 1 includes a main body 101 and a head 102;

[0110] The main body 101 is provided with an installation opening 103 for the head 102 to be installed;

[0111] The driving mechanism 7 is disposed in the main body 101 and connected to the head 102 to drive the head 102 to move.

[0112] The microneedle device 2 is disposed on the head 102;

[0113] The atomization chamber 4021 is disposed in the head portion 102 , and the air supply mechanism 401 is disposed in the main body 101 .

[0114] It should be noted that, since the hyaluronic acid needle utilizes the microneedle device 2 to stimulate the skin and form tiny holes on the skin surface so that the essence can penetrate into the skin to achieve a beauty effect, the microneedle device 2 needs to reciprocate in contact with the skin to better promote the absorption of the essence, and the setting of the driving mechanism 7 is necessary.

[0115] In order to adapt the movement of the microneedle device 2 driven by the driving mechanism 7, the shell 1 needs to be composed of two parts that can move with each other, namely, the main body 101 and the head 102, and then the driving mechanism 7 and the air supply mechanism 401 are arranged in the main body 101, the atomization chamber 4021 is arranged in the head 102, and the microneedle device 2 is arranged in the head 102.

[0116] Optionally, the main body 101 is in a curved arc shape, so that the user can hold it easily without getting tired or slipping.

[0117] Please refer again Fig.11 In this embodiment, the water light instrument further includes a gas delivery hose 8;

[0118] The air inlet 4022 is connected to the air supply mechanism 401 through the air delivery hose 8 .

[0119] It should be noted that, when in use, the head 102 as a whole is moved by the driving mechanism 7, but at the same time, the atomization chamber 4021 located in the head 102 needs to be supplied with gas by the air supply mechanism 401 located in the main body 101 to atomize the essence. Therefore, in order to adapt to the movement, the air inlet 4022 and the air supply mechanism 401 need to be connected by an air supply hose 8 with good flexibility to improve the structural reliability and durability.

[0120] Please refer again Fig.11 In this embodiment, the control mechanism 3 includes a circuit board 301 and a sensor 302 for sensing a human body;

[0121] The circuit board 301 is arranged in the housing 1;

[0122] The sensor 302 is arranged on the housing 1;

[0123] The sensor 302 , the air supply mechanism 401 and the driving mechanism 7 are electrically connected to the circuit board 301 , respectively.

[0124] Optionally, the control mechanism 3 may further include a button, and the button is electrically connected to the circuit board 301 .

[0125] Exemplarily, the buttons may include a plus button and a minus button, and the atomized gas output volume can be adjusted by using the plus button and the minus button.

[0126] It is understandable that the specific function of other structural designs in the hyaluronic acid meter, such as batteries, display screens, charging ports, etc., is to ensure the normal operation of various functions of the hyaluronic acid meter. In view of the fact that these structural designs have been implemented in many existing technologies and are not the focus of this design, they will not be elaborated in depth here.

[0127] It should be noted that during use, when the sensor 302 senses the human body, the circuit board 301 is able to control the battery to supply electrical energy to the gas supply mechanism 401 and the drive mechanism 7, thereby avoiding the water light instrument from doing ineffective work, that is, avoiding the water light instrument from still working when the user forgets to turn off or accidentally turns on the water light instrument, thereby saving energy consumption and improving the intelligence of the water light instrument.

[0128] It can be understood that the sensor 302 can be selected from but not limited to infrared sensors, temperature sensors, capacitive sensors, and resistive sensors. The human epidermis is detected by the sensor 302. When the human epidermis cannot be detected, the circuit board 301 controls the battery to stop supplying power to the air supply mechanism 401 and the drive mechanism 7. When the human epidermis is detected, the circuit board 301 controls the battery to supply power to the air supply mechanism 401 and the drive mechanism 7.

[0129] The utility model provides a hyaluronic acid instrument. Since the gas provided by the gas supply mechanism will form a negative pressure at the gas outlet through the gas flow channel, the essence in the liquid flow channel can be driven to spray out from the liquid outlet, and the sprayed essence is turned into small molecule mist after combining with the gas surrounding it, thereby realizing the atomization of the essence. Compared with the essence in liquid form, the essence in the mist form can not only better penetrate into the skin and be absorbed by the skin, but also can better control the amount sprayed each time and the uniformity of the spraying, so it is not easy to cause waste, thereby improving the user experience.
