[0002] Water-light acupuncture therapy is a fashionable cosmetic procedure that uses tiny needles on microneedle wafers to create pathways through the skin to the dermis, allowing serums to penetrate deeper into the skin.

[0003] At present, the existing water light instrument generally uses a motor to drive two L-shaped connecting rods to drive the micro needle wafer to move back and forth.

Figure 10 The dimension in the H direction, that is, the direction parallel to the rotation output shaft of the motor), and the motor is laterally arranged in a direction parallel to the reciprocating motion direction of the microneedle chip, that is, the rotation output shaft of the motor is parallel to the reciprocating motion direction of the microneedle chip, so that the motor occupies more space in the reciprocating motion direction perpendicular to the microneedle chip, so that the size of the hyaluronic acid analyzer is larger, which is inconvenient to carry and hold, and reduces the user experience.

[0064] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, it is known to those of ordinary skill in the art that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0065] In the description of this application, it should be understood that, unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by those skilled in the art to which this application belongs. In addition, any terminology used is only for the purpose of describing specific embodiments and is not intended to limit this application.

[0066] In addition, numerous specific details are provided in the detailed description below to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0067] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0068] Example 1

[0069] In view of the aforementioned shortcomings of 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 scientific knowledge, has actively engaged in research and innovation, hoping to create a technology that can address these shortcomings and make water light devices more practical. Through continuous research and design, and through repeated trial production and improvements, the applicant has finally created the present utility model, which has proven to be of practical value.

[0070] Please refer to Figure 1-4 The embodiment of the present invention provides a reciprocating drive device, which is applied to a water light instrument. The water light instrument includes a microneedle device. The reciprocating drive device is used to drive the microneedle device to move back and forth, and includes a motor 401 and a connecting component 402;

[0071] One end of the connecting component 402 is connected to the microneedle device, and the other end of the connecting component 402 is eccentrically connected to the rotating output shaft 403 of the motor 401;

[0072] The motor 401 is arranged transversely in a first direction, the rotation output shaft 403 is parallel to the first direction, and the movement direction of the connecting component 402 is parallel to the second direction;

[0073] The first direction is perpendicular to the reciprocating motion direction of the microneedle device, that is, Figure 1 Y direction in;

[0074] The second direction is the reciprocating motion direction of the microneedle device, i.e. Figure 1 The X direction in .

[0075] It should be noted that, since the motor 401 is in the horizontal direction (ie perpendicular to the direction of the rotating output shaft 403, i.e. Figure 1 The size in the X direction in the first direction is large, so if the motor 401 continues to be set horizontally in a direction parallel to the second direction, the problem of the motor 401 occupying more space in the first direction cannot be solved. Therefore, this embodiment makes an improvement by setting the motor 401 horizontally in the first direction, so that the space occupied by the motor 401 in the first direction can be reduced, and the volume of the hyaluronic acid instrument can be reduced, which is not only more convenient to carry and hold, but also helps to improve the grip and user experience, and is also beneficial to the layout of other components in the hyaluronic acid instrument. In other words, through reasonable layout and connection methods, this embodiment successfully matches the longitudinal direction of the motor 401 with the width direction of the hyaluronic acid instrument, thereby reducing the overall volume of the hyaluronic acid instrument without sacrificing function.

[0076] It is understood that after the motor 401 is positioned transversely in the first direction, the rotary output shaft 403 is parallel to the first direction. This makes it impossible for the two L-shaped connecting rods in the prior art to cooperate with the motor 401 to drive the microneedle device for reciprocating motion. Therefore, this embodiment further replaces the two L-shaped connecting rods in the prior art with a connecting assembly 402. The connecting assembly 402 is eccentrically connected to the rotary output shaft 403 and is connected to the microneedle device. The connecting assembly 402 can convert the rotational motion of the rotary output shaft 403 into motion to drive the microneedle device for reciprocating motion.

[0077] Please refer again Figure 1-2 , in this embodiment, further, the connecting assembly 402 includes an eccentric wheel 4021 and a connecting member 4022;

[0078] The eccentric wheel 4021 is connected to the rotation output shaft 403 of the motor 401;

[0079] One end of the connector 4022 is connected to the microneedle device, and the other end is connected to the eccentric wheel 4021 .

[0080] It should be noted that due to the presence of the eccentric wheel 4021, when the motor 401 drives the eccentric wheel 4021 to rotate by rotating the output shaft 403, the eccentric wheel 4021 will drive the connecting member 4022 to perform reciprocating motion, so that the microneedle device, driven by the connecting member 4022, repeatedly contacts and leaves the user's face, thereby achieving a beauty action.

[0081] Please refer again Figure 3-4 In this embodiment, further, the connecting member 4022 includes a first sleeve portion 40221, a connecting portion 40222 and a second sleeve portion 40223 connected in sequence;

[0082] The microneedle device is connected to the first sleeve portion 40221;

[0083] The eccentric wheel 4021 is located in the second sleeve portion 40223 .

[0084] It should be noted that, by providing the sleeve portion, the connection between the connector 4022 and the microneedle device and the eccentric wheel 4021 can be detachable, which can ensure a stable connection and facilitate disassembly and maintenance.

[0085] In this embodiment, a shock-absorbing pad is further provided between the eccentric wheel 4021 and the second sleeve portion 40223;

[0086] And / or, the motor 401 is wrapped with a shock-absorbing sleeve.

[0087] It is understood that to reduce vibration, a shock-absorbing sleeve can be wrapped around the outside of the motor 401 to reduce the impact of vibration generated by the rotation of the motor 401 on the beauty device, while also improving the structural reliability and durability. Similarly, a shock-absorbing pad can be provided between the eccentric wheel 4021 and the second sleeve portion 40223 to increase the connection stability between the eccentric wheel 4021 and the second sleeve portion 40223.

[0088] For example, the shock-absorbing sleeve and the shock-absorbing pad are generally made of materials such as rubber and soft plastic.

[0089] Please refer again Figure 4 In this embodiment, further, the motor 401 is in the first direction (ie Figure 1 The height in the Y direction) is not greater than the maximum width of the first sleeve portion 40221 in the first direction; and / or,

[0090] The maximum width of the motor 401 in the direction perpendicular to the first direction and the second direction is not greater than the maximum width of the first sleeve portion 40221 in the direction perpendicular to the first direction and the second direction.

[0091] Specifically, the first sleeve portion 40221, the connecting portion 40222, and the second sleeve portion 40223 are connected to form an L-shape and an escape space, and the motor 401 is located within the escape space. It can be understood that by arranging the motor 401 within the escape space and connecting the motor 401 to the second sleeve portion 40223 via the eccentric wheel 4021, the dimensions of the motor 401, the eccentric wheel 4021, and the second sleeve portion 40223 in the first direction can be designed to be smaller than the dimension of the first sleeve portion 40221 in the first direction. In this way, the structure of the reciprocating drive device can be made more compact, which is more conducive to the miniaturization design of the product.

[0092] It should be noted that the purpose of this design is also to prevent other components in the reciprocating drive device except the motor from occupying too much space in the first direction, thereby reducing the overall volume of the water light instrument.

[0093] Although the terms "motor," "connecting assembly," and "rotating output shaft" are frequently used in this application, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.

[0094] The utility model provides a reciprocating drive device, which connects one end of a connecting component to a microneedle device in a beauty instrument and eccentrically connects the other end to the rotating output shaft of a motor, and then laterally arranges the motor in a first direction so that the rotating output shaft of the motor is parallel to the first direction and the movement direction of the connecting component is parallel to the second direction, thereby reducing the space occupied by the motor in the first direction, reducing the size of the hyaluronic acid device, making it easier to carry and hold, and improving the user experience.

[0095] Example 2

[0096] Please refer to Figure 5-9 The embodiment of the present utility model provides a water light instrument, comprising a housing 1, a microneedle device, a control mechanism 3 and a reciprocating drive device 4 as described in the first embodiment above;

[0097] The microneedle device includes a microneedle wafer 2;

[0098] The reciprocating drive device 4 is disposed in the housing 1 , and the motor 401 is electrically connected to the control mechanism 3 ;

[0099] The microneedle wafer 2 is connected to the reciprocating drive device 4 .

[0100] It should be noted that the microneedle wafer 2 can stimulate the skin after contacting the skin, forming tiny holes on the skin surface so that the essence can penetrate into the skin to achieve a beauty effect.

[0101] It is understandable that since the microneedle chip 2 needs to be in reciprocating contact with the skin to better promote the absorption of the essence, the provision of the reciprocating drive device 4 is necessary, and the purpose is to drive the microneedle chip 2 to reciprocate through the reciprocating drive device 4.

[0102] Please refer again Figure 5 and Figure 8-9 In this embodiment, further, the housing 1 includes a main body 101 and a head 102;

[0103] The main body 101 is provided with an installation opening 103 for the head 102 to be installed;

[0104] The reciprocating drive device 4 is disposed in the main body 101 and connected to the head 102 to drive the head 102 to reciprocate;

[0105] The microneedle wafer 2 is disposed on the head 102 .

[0106] It should be noted that in order to adapt to the movement of the microneedle chip 2 driven by the reciprocating drive device 4, 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 reciprocating drive device 4 is set in the main body 101, and the microneedle chip 2 is set in the head 102.

[0107] Optionally, the main body 101 is in a curved arc shape, so that the user can hold it easily without getting tired or slipping.

[0108] It can be understood that when the microneedle wafer 2 is set on the head 102, the head 102 is inserted into the first sleeve portion 40221, and the head 102 is engaged with the first sleeve portion 40221, as shown in FIG. Figure 6 shown.

[0109] In this embodiment, the microneedle device further includes an atomization component;

[0110] The atomizing assembly is disposed in the housing 1 and is used to atomize and spray the liquid.

[0111] It should be noted that, considering 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 sprayed each time and the uniformity of the spraying, so as not to cause waste, the microneedle device of this embodiment further includes an atomization component for atomizing the essence before it reaches the facial skin of the human body.

[0112] Please refer again Figure 5 and Figure 7-8 In this embodiment, the head 102 is provided with an atomizing outlet 7, which is connected to the atomizing assembly;

[0113] An avoidance hole 8 is provided at a position of the microneedle wafer 2 corresponding to the atomization outlet 7; and / or, the microneedle wafer 2 and the atomization outlet 7 are arranged side by side.

[0114] It should be noted that since the area where the microneedle chip 2 is located needs to cover the area where the atomization outlet 7 is located, and the microneedle chip 2 is designed to have an avoidance hole 8 at the position corresponding to the atomization outlet 7, the atomized essence can be sprayed out from the atomization outlet 7 and the avoidance hole 8 in turn, and finally reach the skin stimulated by the microneedle chip 2.

[0115] The microneedle chip 2 can also be arranged side by side with the atomization outlet 7. Specifically, it includes the microneedle chip 2 being close to the atomization outlet 7 and arranged in parallel with it. When the microneedle chip 2 is arranged in the shell 1, a gap is formed between the microneedle chip 2 and the shell 1, and the essence atomized by the atomization component is able to overflow from the peripheral side of the microneedle chip 2, that is, the peripheral side of the microneedle chip 2 forms an atomization outlet. The microneedle chip 2 and the atomization outlet 7 are arranged side by side, and of course it should also include the situation where the atomization outlet 7 is arranged on the peripheral side of the microneedle chip 2. The peripheral side misting method can make the mist spread more evenly and quickly, and improve the uniformity of the mist adhering to the skin. Of course, on this basis, an avoidance hole 8 can also be opened in the microneedle chip 2 at the same time. At this time, the avoidance hole 8 can also be used as a part of the atomization outlet 7, so as to increase the mist outlet area and increase the mist outlet amount, and at the same time, it can also make the mist sprayed on the skin more uniform.

[0116] Optionally, the avoidance hole 8 is opened at the center of the microneedle chip 2, and the avoidance hole 8 is coaxially arranged with the atomization outlet 7 to ensure that the skin area stimulated once by the microneedle chip 2 can evenly absorb the atomized essence.

[0117] Please refer again Figure 5 In this embodiment, the water light instrument further includes an atomizing mechanism 5 and an air supply mechanism 6;

[0118] The atomizing mechanism 5 is arranged in the head portion 102, and the air supply mechanism 6 is arranged in the main body portion 101;

[0119] like Figure 7 As shown, the atomization mechanism 5 includes an atomization chamber 501, which is provided with an air inlet 502, an air outlet 503, a liquid inlet 504 and a liquid outlet 505, and a gas flow channel 506 and a liquid flow channel 507 are provided in the atomization chamber 501;

[0120] One end of the liquid flow channel 507 is connected to the liquid inlet 504, and the other end of the liquid flow channel 507 is connected to the liquid outlet 505;

[0121] One end of the gas flow channel 506 is connected to the gas inlet 502, and the other end of the gas flow channel 506 is connected to the gas outlet 503;

[0122] The air inlet 502 is communicated with the air supply mechanism 6 , and the air outlet 503 surrounds part or all of the liquid outlet 505 .

[0123] It should be noted that this embodiment is based on the principle of gas path atomization. High-speed gas is provided by the gas supply mechanism 6, and then the high-speed gas is transported to the gas flow channel 506. The high-speed gas is used to form a negative pressure at the gas outlet 503, which can drive the essence in the liquid flow channel 507 to be ejected from the liquid outlet 505, and the ejected essence is transformed into a small molecule mist after combining with the high-speed gas surrounding it, thereby realizing the atomization of the essence.

[0124] It is understandable that the atomized essence can be introduced into the dermis, opening millions of channels in the epidermis of several square millimeters without damaging the epidermis, allowing the active ingredients of the essence to effectively penetrate the skin, stimulating collagen proliferation and cell regeneration, repairing aging cells, and improving beauty and skin care effects.

[0125] Exemplarily, the air supply mechanism 6 may be an air pump.

[0126] Please refer again Figure 5 and Figure 7 In this embodiment, the water light instrument further includes a gas delivery hose 9;

[0127] The air inlet 502 is connected to the air supply mechanism 6 through the air hose 9.

[0128] It should be noted that, when in use, the head 102 as a whole is driven by the reciprocating drive device 4 to make reciprocating motion, but at the same time, the atomization chamber 501 located in the head 102 needs to be supplied with gas by the air supply mechanism 6 located in the main body 101 to atomize the essence. In order to adapt to the reciprocating motion, the air inlet 502 and the air supply mechanism 6 need to be connected by an air supply hose 9 with good flexibility to improve the structural reliability and durability.

[0129] Please refer again Figure 5 In this embodiment, the control mechanism 3 includes a circuit board 301 and a sensor 302 for sensing the human body;

[0130] The circuit board 301 is arranged in the housing 1;

[0131] The sensor 302 is provided in the housing 1;

[0132] The sensor 302 , the air supply mechanism 6 and the motor 401 are electrically connected to the circuit board 301 , respectively.

[0133] Optionally, the control mechanism 3 may further include a button, which is electrically connected to the circuit board 301 .

[0134] For example, the buttons may include a plus button and a minus button, and the atomized air volume can be adjusted by using the plus button and the minus button.

[0135] It is understandable that the specific function of other structural designs in the hyaluronic acid analyzer, such as batteries, display screens, charging interfaces, etc., is to ensure the normal operation of various functions of the hyaluronic acid analyzer. 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.

[0136] 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 air supply mechanism 6 and the reciprocating drive mechanism 4, thereby avoiding the water light instrument from doing ineffective work, that is, avoiding the air supply mechanism 6 and the reciprocating drive mechanism 4 from still working when the user forgets to turn off or accidentally turns on the water light instrument, saving energy consumption and improving the intelligence of the water light instrument.

[0137] It can be understood that the sensor 302 can be selected from but not limited to infrared sensors and temperature 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 6 and the reciprocating drive mechanism 4. When the human epidermis is detected, the circuit board 301 controls the battery to supply power to the air supply mechanism 6 and the reciprocating drive mechanism 4.

[0138] The utility model provides a hyaluronic acid device, which connects one end of a connecting component to a microneedle chip in a beauty device and eccentrically connects the other end to a rotating output shaft of a motor, and then arranges the motor perpendicular to the reciprocating motion direction of the microneedle chip, so that the rotating output shaft of the motor is perpendicular to the reciprocating motion direction of the microneedle chip, and the motion direction of the connecting component is parallel to the reciprocating motion direction of the microneedle chip, thereby reducing the space occupied by the motor in the reciprocating motion direction perpendicular to the microneedle chip, reducing the size of the hyaluronic acid device, making it easier to hold, and improving the user experience.
