When one component is considered to be “arranged on” another component, it can be directly arranged on the other component or there can be a component arranged in the middle at the same time.

[0121] In addition, the terms “long”, “short”, “inner”, “outer”, and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used for the convenience of describing the present application, and do not indicate or imply that the device or element referred to must have this particular orientation, be constructed in this particular orientation, and operate in this particular orientation, which cannot be understood as a limitation of the present application.

[0122] In a conventional essence application cosmetic instrument product, the essence is usually applied by spraying, in which case the essence quickly spreads before contacting the skin, resulting in the user being unable to control the application of the essence when precise application is desired, such as around the eyes, and the spraying method is extremely likely to cause the essence to enter the eyes and cause damage to the eyes, and thus further improvement is still needed.

[0123] The technical solutions of the present application will be further described below in conjunction with Figs. 1-34 and through specific embodiments.

[0124] [About a cosmetic instrument combining negative pressure adsorption and essence application function]

[0125] Please refer to Figs. 1-3, the present application provides a cosmetic instrument for skin care, which mainly includes a cosmetic instrument body 1, a negative pressure cavity 2, a negative pressure channel 4 and a negative pressure mechanism 5.

[0126] Among them, the cosmetic instrument body 1 mainly provides assembly positions for various parts, and in the specific setting, the negative pressure cavity 2 is first set at one end of the cosmetic instrument body 1, and at the same time, a liquid storage cavity 6 for storing essence is also provided on the cosmetic instrument, and the negative pressure cavity 2 is in communication with the liquid storage cavity 6, so that the essence can flow into the negative pressure cavity 2 under the action of external force.

[0127] In some embodiments, the cosmetic instrument further includes a cosmetic component 3, and the cosmetic component 3 includes a cosmetic head 31, which is used to contact the skin and play a cosmetic role. The cosmetic head 31 includes an adsorption element 3123 located in the negative pressure cavity 2. The adsorption element 3123 can have a porous structure, which can retain the essence flowing into the negative pressure cavity 2, so as to facilitate the cosmetic head 31 to apply the essence to the skin. Specifically, the outward opening in the porous structure of the adsorption element 3123 can become a liquid outlet 1002 for applying the essence to the skin.

[0128] In some embodiments, the negative pressure mechanism 5 is provided on the cosmetic instrument body 1, and the negative pressure mechanism 5 is connected with the negative pressure channel 4 and is used to suck gas in the negative pressure channel 4. Specifically, the negative pressure channel 4 sequentially connects the liquid storage cavity 6, the negative pressure cavity 2 and the negative pressure mechanism 5, and the negative pressure mechanism 5 forms a negative pressure area for sucking the skin in the negative pressure cavity 2 through the negative pressure channel 4, and the essence is pumped from the liquid storage cavity 6 to the cosmetic head 31 and applied to the skin through the cosmetic head 31.

[0129] In the technical solutions of the present application, the skin area where the essence needs to be applied is adsorbed in the negative pressure area by negative pressure adsorption, which improves the control of the application area of the essence and reduces unnecessary damage caused by the spreading of the essence.

[0130] In addition, the above scheme only needs to set one negative pressure driving source, i.e., the negative pressure mechanism 5, which can form negative pressure at the liquid storage cavity 6 and the beauty head 31 under the action of the negative pressure channel 4, realize the effect of synchronous liquid output and negative skin suction, on the one hand, can simplify the overall pipeline structure, reduce the number of power sources required for execution, make the structure more compact, and realize the compactness of the beauty instrument; on the other hand, by setting the adsorption element 3123, the extracted essence can be retained in the adsorption element 3123, so that when the beauty head 31 contacts the skin, the possibility of excessive backflow of the essence to the latter half of the negative pressure channel 4 under the condition of negative pressure can be reduced, more essence can be applied to the skin, the influence of the negative pressure environment on the overall flow of the essence is greatly reduced, the beauty effect is guaranteed, the negative pressure and liquid output functions can be realized at the same time, and the technical difficulty of synchronously combining the negative suction function and the liquid output function is overcome.

[0131] [About the negative pressure channel 4]

[0132] In some embodiments, the negative pressure channel 4 includes a first segment for connecting the liquid storage cavity 6 and the negative pressure cavity 2, and a second segment for connecting the negative pressure cavity 2 and the negative pressure mechanism 5. It can be understood that the negative pressure channel 4 can be a flow channel naturally formed by the internal structure design, part arrangement and stacking of the beauty instrument body 1; the negative pressure channel 4 can also be a tubular passage integrally formed in the interior of the beauty instrument body 1; in addition, the negative pressure channel 4 can also be a pipe structure independent of the beauty instrument body 1. Optionally, the pipe structure can be a hose structure.

[0133] It can be understood that the design of the tubular passage and the pipe structure can make the channel smoother and the fluid transportation more smooth; the design of the tubular passage has higher assembly efficiency, and the design of the pipe structure is more convenient for production and assembly.

[0134] In some embodiments, referring to FIGS. 2 and 3, in order to make the structure more compact, the negative pressure channel 4 can be designed in an integrated manner. In this embodiment, the beauty instrument further includes a main body 32 arranged on the beauty instrument body 1, and the beauty head 31 is arranged on the main body 32. Generally, the beauty head 31 can be arranged on the main body 32 in a fixed connection or detachable connection manner. When the beauty head 31 is detachably arranged on the main body 32, the beauty head 31 can be detached and replaced compared with the main body 32, so as to regularly replace the beauty head 31 and keep the beauty head 31 part clean and tidy. In addition, when the beauty head 31 is fixed on the main body 32, the beauty head 31 and the main body 32 form a modular structure at this time, so as to realize one-time production. The main body 32 is hollow and has a shell-shaped structure, and the main body 32 is internally provided with a first negative pressure pipeline 41 and a second negative pressure pipeline 42. The first negative pressure pipeline 41 mainly plays a liquid output role, and the second negative pressure pipeline 42 plays a negative pressure suction role.

[0135] In some embodiments, referring to FIGS. 3 and 4, the first negative pressure pipeline 41 can be installed inside the main body 32 and form a first section of the negative pressure channel 4, with one end of the first negative pressure pipeline 41 connected to the beauty head 31 and in communication with the negative pressure cavity 2, and the other end connected to the liquid storage cavity 6. The first negative pressure pipeline 41 guides the flow of essence liquid to the beauty head 31 to achieve the liquid output effect.

[0136] It can be understood that the main body 32 is arranged in the beauty instrument body 1, which means that the main body 32 can be connected to one side of the beauty instrument body 1, or the main body 32 can also be arranged in the beauty instrument body 1. The main body 32 is located in the beauty instrument body 1, which can make the structure more compact.

[0137] Further, the second negative pressure pipeline 42 can also be installed inside the main body 32 and form a second section of the negative pressure channel 4, with one end of the second negative pressure pipeline 42 in communication with the negative pressure cavity 2 and the other end connected to the negative pressure mechanism 5.

[0138] At this time, by arranging the first negative pressure pipeline 41 and the second negative pressure pipeline 42 inside the hollow main body 32, the first negative pressure pipeline 41 and the second negative pressure pipeline 42 can construct and form the negative pressure channel 4. The hollow main body 32 has a light structure and low manufacturing cost. At the same time, by arranging the first negative pressure pipeline 41 and the second negative pressure pipeline 42 inside, the integration of the structure can form two independent flow circuits, in which the first negative pressure pipeline 41 is responsible for liquid outflow, and the second negative pressure pipeline 42 is responsible for gas adsorption. The two operate independently and are not easy to interfere with each other, and are convenient for production and assembly and have a compact structure.

[0139] In some embodiments, the first negative pressure pipeline 41 and the second negative pressure pipeline 42 can be a tubular passage integrally formed inside the main body 32, which is convenient to assemble; or can be an independent pipe structure arranged inside the main body 32, which is convenient for production and has low manufacturing cost. Further, the first negative pressure pipeline 41 can adopt a hose structure, which is conducive to the assembly of the structure, while the second negative pressure pipeline 42 can adopt a hard pipe structure, which can prevent the second negative pressure pipeline 42 from deforming during negative pressure extraction and keep the inside unobstructed, thereby better realizing the negative suction function.

[0140] In some embodiments, referring to FIGS. 2 to 7, in order to improve the operation convenience and sanitary safety, the main body 32 and the beauty instrument body 1 are arranged in a detachable connection.

[0141] Specifically, referring to FIG. 2, the cosmetic instrument body 1 has a mounting port 102 for the main body 32 to be disassembled. To ensure the smooth assembly of the negative pressure channel 4 and the negative pressure mechanism 5 arranged in the main body 32, in combination with FIGS. 6 and 7, the cosmetic instrument is provided with a communication part 11 that can be assembled and connected with each other. The communication part 11 further includes a first communication part 111 and a second communication part 112 to realize the communication of the negative pressure channel 4 and the negative pressure mechanism 5.

[0142] Specifically, the first communication part 111 is arranged in the main body 32 and connected with the second negative pressure pipeline 42, and the second communication part 112 is connected with the negative pressure mechanism 5. The specific arrangement of the second communication part 112 will be described in detail in the subsequent description.

[0143] Further, referring to FIG. 7, to ensure the air tightness of the connection between the negative pressure channel 4 and the negative pressure mechanism 5, a gas inlet sealing ring 113 is arranged at the connection between the first communication part 111 and the second communication part 112. Specifically, the first communication part 111 is inserted into the second communication part 112 to realize the connection, and the position where the first communication part 111 is inserted into the second communication part 112 is sleeved with the gas inlet sealing ring 113.

[0144] In some embodiments, referring to FIG. 3, to control the slow and uniform flow of the essence liquid to the outside, a slow flow design can be added. In one implementation, a slow flow part 43 can be arranged in the negative pressure channel 4. The slow flow part 43 has a porous structure, which can be made of sponge, cotton, porous silica gel or porous ceramic, and other structures that can achieve the slow flow effect can be tried, which are not limited here. The slow flow part 43 is arranged between the liquid storage cavity 6 and the cosmetic head 31, and the porous structure can slow down the flow rate of the essence liquid. In this case, the essence liquid can be evenly and slowly delivered to the cosmetic head 31, realizing stable liquid output effect.

[0145] The arrangement of the slow flow part 43 also facilitates later use and maintenance. For example, when the negative pressure channel 4 is blocked, the problem can be solved by replacing the slow flow part 43, which is simple and fast. In another implementation, the slow flow effect can also be achieved by reducing the inner diameter of the negative pressure channel 4. Specifically, the inner diameter of the negative pressure channel 4 between the liquid storage cavity 6 and the cosmetic head 31 is arranged to be smaller than that of the other parts, or when the negative pressure channel 4 between the liquid storage cavity 6 and the cosmetic head 31 is designed as a hose, a clamping groove is arranged at any position outside the hose, the hose is arranged in the clamping groove, and the inner diameter of the hose in the clamping groove is reduced. By limiting the inner diameter of the negative pressure channel 4 through structural design, the structural design is simple, and the manufacturing cost can be reduced.

[0146] [About the negative pressure mechanism 5]

[0147] Please refer to FIG. 2, in some embodiments, the negative pressure mechanism 5 comprises a negative pressure pump 51, which is fixedly installed in the inside of the beauty instrument body 1, and the suction end of the negative pressure pump 51 is connected with the second section of the negative pressure channel 4, for extracting air from the negative pressure channel 4.

[0148] In an implementation, the negative pressure mechanism 5 further comprises a solenoid valve 52. The solenoid valve 52 is also connected with the negative pressure channel 4, for supplementing gas to the negative pressure channel 4, to break the negative pressure state in the negative pressure cavity 2, so that the user can smoothly remove the beauty instrument from the skin without causing harm to the skin.

[0149] In some embodiments, in order to realize automatic control of the negative pressure pump 51 and the solenoid valve 52, the beauty instrument further comprises a main control circuit board 17, on which a control element 55 is arranged. The negative pressure mechanism 5 further comprises an air pressure sensor 53 arranged on the main control circuit board 17. Wherein, the receiving end of the air pressure sensor 53 is connected with the negative pressure channel 4, the air pressure sensor 53 can detect the negative pressure condition in the negative pressure channel 4, and then the negative pressure condition of the negative pressure cavity 2 can be obtained, and a negative pressure signal is synchronously generated. In addition, the control element 55 is connected with the air pressure sensor 53, the negative pressure pump 51 and the solenoid valve 52 respectively, the control element 55 can adopt a control chip, and any element that can realize control function can be used, which is not specifically limited here.

[0150] Based on this, after the air pressure sensor 53 obtains the negative pressure signal according to the air pressure condition in the negative pressure channel 4, the negative pressure signal is sent to the receiving end of the control element 55, the control element 55 analyzes the negative pressure signal and forms a control signal, and then the control element 55 sends the control signal to the negative pressure pump 51 and the solenoid valve 52 correspondingly, to control the start and stop of the negative pressure pump 51 and the solenoid valve 52, realize automatic control, and optimize the use experience. Wherein, the control element 55 can be a central processing unit (CPU) or a microcontroller unit (MCU), and can also be other general-purpose processors, digital signal processors (DSP), application specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc.

[0151] In some embodiments, in order to optimize the compactness of the internal pipeline, the cosmetic device further comprises a multi-way valve 54, which comprises at least four interfaces in communication with each other, the number of interfaces being related to the number of elements required to be communicated by the negative pressure channel 4, and in this embodiment, four interfaces are selected, i.e. a four-way valve structure, and the number of interfaces is not specifically limited. Based on this, the air pressure sensor 53, the negative pressure pump 51, the electromagnetic valve 52 and the negative pressure channel 4 are correspondingly connected to the interfaces of the multi-way valve 54. Here, the multi-way valve 54 can integrate the air pressure sensor 53, the negative pressure channel 4, the electromagnetic valve 52 and the negative pressure pump 51 together through the interfaces, so that the internal pipeline is more compact.

[0152] [About the liquid storage cavity 6]

[0153] In some embodiments, the liquid storage cavity 6 can be formed in the cosmetic body; or, when the cosmetic device is provided with the main body 32, the liquid storage cavity 6 can be formed in the main body 32; or, the liquid storage cavity 6 can be the accommodation space of a container 61. The following will be described in detail with respect to the above specific embodiments.

[0154] Please refer to FIG. 8, in the embodiment in which the liquid storage cavity 6 is formed in the main body 32, the cosmetic device can be considered as a cosmetic device comprising the liquid storage cavity 6. Specifically, a partition plate 62 is arranged in the main body 32, and an independent space is separated by the partition plate 62, which can constitute the liquid storage cavity 6 for storing the essence liquid. Meanwhile, an adding port 63 is arranged in the main body 32, through which the essence liquid can be supplemented. Through this arrangement, while ensuring the basic function of delivering the essence liquid, it can also support users to inject different essence liquids according to their needs, meeting the different needs of users.

[0155] It can be understood that when the main body 32 is arranged in a non-detachable manner with the cosmetic body 1, the main body 32 has the adding port 63 for supplementing the essence liquid, and the user can supplement the essence liquid into the liquid storage cavity 6 through the adding port 63. Correspondingly, when the main body 32 is fixedly arranged in the cosmetic body 1, the cosmetic body 1 also needs to be provided with an opening corresponding to the position of the adding port 63 of the main body 32, so as to realize the supplement of the essence liquid.

[0156] Through this arrangement, a highly integrated effect can be achieved, and the main body 32 can well realize the functions of storing the essence liquid and accommodating the negative pressure channel 4.

[0157] In order to further improve the operation convenience, the main body 32 can be arranged in a detachable manner with the cosmetic body 1. It can be understood that at this time, the cosmetic body 1 can no longer be provided with an opening corresponding to the adding port 63 of the main body 32. Through this arrangement, the design of the cosmetic body 1 can be simplified, and the convenience of the user to supplement the essence liquid can also be improved.

[0158] In addition, the main body 32 can also not be provided with the adding port 63, at this time, the main body 32 is provided with consumables, when the essence liquid in the main body 32 is consumed, the original main body 32 can be directly replaced with a new main body 32 to start the next round of beauty care. Through the design, the convenience is further improved, and the sanitary safety is also improved, and the user experience is further improved.

[0159] However, although the liquid storage cavity 6 is directly integrated in the main body 32, it is not conducive for the user to observe the remaining amount of the liquid. In order to further optimize the use experience, the main body 32 and / or the beauty instrument body 1 can be provided with a transparent window, through which the remaining amount of the essence liquid can be observed.

[0160] Specifically, when the main body 32 is connected to one end of the beauty instrument body 1 and located outside the beauty instrument body 1, only the transparent window needs to be provided on the main body 32; when the main body 32 is arranged in the beauty instrument body 1, not only the transparent window needs to be provided on the main body 32, but also the transparent window needs to be provided on the beauty instrument body 1 corresponding to the transparent window of the main body 32. It can be understood that if the main body 32 is made of a transparent material, the cavity wall forming the liquid storage cavity 6 can be understood as the transparent window.

[0161] In the embodiment in which the liquid storage cavity 6 is formed in the beauty instrument body 1, the beauty instrument can also be considered as including the liquid storage cavity 6, and can also be understood as directly arranging the liquid storage cavity 6 on the beauty instrument body 1. The specific implementation manner of the liquid storage cavity 6 is the same as that of forming the liquid storage cavity 6 in the main body 32. It can be understood that at this time, the beauty instrument body 1 can be provided with the adding port 63 according to the need of supplementing the essence liquid, and can be provided with the transparent window according to the need of observing the remaining amount of the essence liquid, and other specific settings will not be described here.

[0162] Please refer to FIG. 9, in the manner of arranging the containing space of the container 61 as the liquid storage cavity 6, the container 61 is located outside the beauty instrument body 1 and connected with the beauty instrument body 1. The container 61 can be a vial structure, a soft bag structure or other containers 61 capable of storing essence liquid, in this embodiment, a vial structure with higher sanitary standard is selected, at this time, the internal containing space of the container 61 forms the liquid storage cavity 6, further optimizing the convenience of observing the remaining amount of the essence liquid.

[0163] In this embodiment, referring to FIG. 10, the beauty instrument and the container 61 constitute a beauty kit, when the container 61 is assembled on the beauty instrument body 1, the container 61 is in communication with the negative pressure mechanism 5 through the negative pressure channel 4, thereby realizing the supply and delivery of the essence liquid. The arrangement of the negative pressure channel 4 and the negative pressure mechanism 5 is as described above, and will not be described here.

[0164] In this embodiment, referring to FIGS. 9 and 10, to realize the mutual assembly of the beauty kit, the beauty instrument is provided with a connecting portion 33, after the container 61 is assembled with the beauty instrument through the connecting portion 33, the beauty instrument can be in communication with the container 61, then the essence liquid is taken out from the container 61, and the essence liquid is delivered to the human skin, thereby realizing the skin care.

[0165] Please refer to FIG. 10, specifically, the beauty instrument is provided with a bottle mouth slot 339 for inserting the container 61, the slot bottom of the bottle mouth slot 339 is provided with a plug-in portion 330, and the connecting portion 33 comprises the aforementioned bottle mouth slot 339 and the plug-in portion 330.

[0166] At this time, when the container 61 is inserted into the bottle mouth slot 339, on the one hand, the bottle mouth slot 339 can clamp the container 61 to limit the container 61 from separating from the beauty instrument, and on the other hand, the connecting portion 33 is inserted into the container 61 to take the essence liquid from the container 61.

[0167] Specifically, to achieve the above purpose, when a new container 61 needs to be replaced, the head of the container 61 is inserted downward into the bottle mouth slot 339, and under the clamping action of the bottle mouth slot 339, the container 61 will not separate from the bottle mouth slot 339 of the main body 32; when the head of the container 61 is inserted downward into the bottle mouth slot 339; synchronously, the connecting portion 33 is inserted upward into the container 61 to take the essence liquid or other functional liquid (such as cleaning liquid for cleaning the liquid flow channel) from the container 61; when the essence liquid or other functional liquid in the container 61 is used up, the container 61 can be directly pulled out upward.

[0168] During the assembly and disassembly process of the container 61, no complicated screwing operation is needed, only simple plugging and unplugging operation is needed, and the operation is very convenient. Therefore, the present setting can effectively solve the problem that the existing beauty instrument kit assembled by threads needs to be screwed, and the convenience is poor.

[0169] In some embodiments, referring to FIGS. 5 and 9, in order to smoothly deliver the essence liquid in the container 61 to the beauty head 31, the plug-in portion 330 is respectively provided with a flow outlet 331 and an air inlet 332. One end of the first section of the negative pressure channel 4 is fixedly connected with the plug-in portion 330 and is in communication with the flow outlet 331. The air inlet 332 is exposed outside to realize the communication between the container 61 and the outside. It can be understood that because of the tension of the essence liquid itself, the essence liquid itself is not easy to flow out from the air inlet 332 when the plug-in portion 330 is connected with the container 61.

[0170] Through the above arrangement, the flow outlet 331 and the air inlet 332 are integrated on the plug-in part 330, so that when the plug-in part 330 is inserted into the container 61, the inside of the container 61 is simultaneously communicated with the outside and the negative pressure channel 4, and the atmospheric pressure balance between the inside and outside of the container 61 is maintained through the air inlet 332 while the negative pressure is formed in the negative pressure channel 4, so that the liquid outlet is smoother.

[0171] In some embodiments, referring to FIGS. 5 and 10 again, the slot wall of the bottle mouth slot 339 is provided with a plurality of outwardly protruding slot wall bosses 338; the slot wall bosses 338 are used to limit the container 61 from being separated from the bottle mouth slot 339. Correspondingly, the container 61 comprises a bottle body 611 for storing the essence liquid, a bottle nozzle 612 for being inserted into the bottle mouth slot 339, and a bottle neck 613 connecting the bottle body 611 and the bottle nozzle 612. The outer edge of the bottle nozzle 612 protrudes from the bottle neck 613, so that the outer edge of the bottle nozzle 612 is clamped with each slot wall boss 338 of the beauty instrument.

[0172] The slot wall of the bottle mouth slot 339 in this embodiment is provided with the outwardly protruding slot wall bosses 338, which can effectively clamp the edge of the container 61 and prevent the container 61 from being accidentally separated after being inserted into the bottle mouth slot 339. That is, when the container 61 is inserted into the slot, the outer edge of the bottle nozzle 612 is closely matched with the slot wall boss 338, which ensures the stability of the container 61 in the beauty instrument, so that the user does not need to worry about the loosening of the container 61 when performing skin care, and the use safety and the stability of the liquid supply are improved.

[0173] Optionally, as shown in FIG. 10, the container 61 further comprises a sealing plug 614 for sealing the bottle nozzle 612, and an aluminum film 615 covering the sealing plug 614 and the bottle nozzle 612. The sealing plug 614 is provided with a plug hole 6141 for inserting the plug-in part 330, and a frangible film 6142 for covering the plug hole 6141, and the aluminum film 615 is provided with a film avoiding hole corresponding to the position of the plug hole 6141 for the connecting part 33 to pass through.

[0174] When the plug-in part 330 is not inserted into the plug hole 6141, the frangible film 6142 can seal the plug hole 6141, so as to avoid the liquid in the container 61 from being polluted by the environment, ensure safety and health, and avoid the essence liquid in the container 61 from flowing out, so as to store and transport. When the container 61 is inserted into the bottle mouth slot 339, the plug-in part 330 is inserted into the plug hole 6141, and the frangible film 6142 is pierced by the plug-in part 330, so as to realize the outflow of the essence liquid. This design not only ensures the sealing of the container 61, but also is convenient to use. The aluminum film 615 is mainly used for limiting the sealing plug 614 and the bottle nozzle 612, so as to avoid the sealing plug 614 from being blown out of the bottle nozzle 612 under the action of air pressure when the pressure in the container 61 is high.

[0175] Further, in this embodiment, the plug-in part 330 is provided in a columnar or conical shape. The opening of the container 61 or the plug-in part 330 can be provided with an elastic structure such as flexible rubber, etc., so that the plug-in part 330 and the container 61 form an interference fit to avoid leakage of the essence from the connection therebetween.

[0176] Optionally, referring to FIGS. 10 and 11, the plug-in part 330 includes a top surface in the form of a conical surface structure 334 and a circumferential side surface in the form of a cylindrical surface structure 335. The circumferential side surface of the cylindrical surface structure 335 is used to form an interference fit with the hole wall of the plug hole 6141 of the container 61 to seal the gap between the plug-in part 330 and the container 61.

[0177] When the container 61 is inserted into the bottle mouth slot 339, the conical surface structure 334 pierces the frangible film, and the cylindrical surface structure 335 forms an interference fit with the inner wall of the plug hole 6141 to ensure the sealing and stability of the essence during transmission. The top surface of the conical surface structure 334 facilitates the plug-in part 330 to easily pierce the frangible film 6142, saving the effort required to pierce the frangible film 6142. The circumferential side surface of the cylindrical surface structure 335 can increase the abutting area between the hole wall of the plug hole 6141 and the plug-in part 330 to improve the sealing performance between the plug-in part 330 and the sealing plug 614.

[0178] It can be understood that the plug-in angle of the vial can be set to be multiple, and at this time, taking the plane where the liquid outlet 1002 is located as a reference, the length direction of the beauty instrument is also perpendicular to the plane, at this time, the angle formed between the extension direction of the plug-in part 330 and the plane where the liquid outlet 1002 is located is between 0 degrees and 90 degrees, at this time, the plug-in angle of the vial perpendicular to the length direction of the beauty instrument to parallel to the length direction of the beauty instrument can be obtained, and at this angle, the plug-in assembly of the vial can be realized, and the shape of the beauty instrument body 1 and the structure angle of the plug-in part 330 can be adjusted according to actual needs to meet the plug-in effect, which is not limited specifically herein, and in this embodiment, the angle is selected as 0 degrees for example.

[0179] In summary, the related settings of the connection part 33 and the container 61 have the following advantages:

[0180] ①The bottle mouth slot 339 for inserting the container 61 is provided on the beauty instrument, and subsequent assembly and disassembly of the container 61 does not require complicated screwing operation, but only simple plugging and unplugging operation, which is convenient to operate;

[0181] ②The conical surface structure 334 and the cylindrical surface structure 335 of the connection part 33 ensure the interference fit with the plug hole 6141 of the container 61 to achieve good sealing during the transmission of the essence and avoid leakage;

[0182] ③ The sealing plug 614 and the frangible membrane 6142 of the container 61 are designed so that the container 61 remains sealed during storage and transportation, ensuring the quality and activity of the essence.

[0183] It can be understood that there are many structures of the connecting part 33 that can achieve plug-in communication, and the present embodiment provides another connecting part 33 suitable for the beauty instrument and the beauty kit in the foregoing embodiments, which can also achieve the functions of air supply and liquid delivery.

[0184] Based on the setting of the foregoing communication part 11, the unexplained features are explained by the foregoing embodiments, which will not be described here. Referring to FIG. 12, the difference between the setting mode of the connecting part 33 structure and the foregoing embodiments is that:

[0185] The connecting part 33 includes an air inlet needle tube 336 for delivering air to the container 61, and a liquid outlet needle tube 337 for delivering liquid out of the container 61.

[0186] Correspondingly, the sealing plug 614 is provided with an air inlet needle hole 6143 for the air inlet needle tube 336 to insert, an air inlet film covering the air inlet needle hole 6143, a liquid outlet needle hole 6144 for the liquid outlet needle tube 337 to insert, and a liquid outlet film covering the liquid outlet needle hole 6144.

[0187] When the container 61 is inserted into the bottle mouth slot 339, the air inlet needle tube 336 and the air inlet film are aligned first, and the liquid outlet needle tube 337 and the liquid outlet film are aligned; then the container 61 is pressed downward, so that the air inlet needle tube 336 pierces the air inlet film and inserts into the container 61 through the air inlet needle hole 6143, and the liquid outlet needle tube 337 pierces the liquid outlet film and inserts into the container 61 through the liquid outlet needle hole 6144. At this time, the air inlet needle tube 336 is in interference fit with the air inlet needle hole 6143 to seal the air inlet needle hole 6143, and the liquid outlet needle tube 337 is in interference fit with the liquid outlet needle hole 6144 to seal the liquid outlet needle hole 6144.

[0188] The connecting part 33 provided by the foregoing setting mode can also take liquid from the container 61 through the design of the air inlet needle tube 336 and the liquid outlet needle tube 337, and how to take the essence from the container 61 by the action of pressure difference will not be described here.

[0189] From the foregoing cosmetic instrument settings can be understood, in the way of the container 61 containing space is set as a liquid storage chamber 6, the connection part 33 setting object due to the cosmetic instrument settings, there are two cases: one, when the cosmetic instrument is not provided with the main body 32, the connection part 33 is set in the cosmetic instrument body 1, the container 61 is connected with the cosmetic instrument body 1 through the connection part 33; The second, when the cosmetic instrument is provided with the main body 32, the connection part 33 is set in the main body 32, and the container 61 is connected with the main body 32 through the connection part 33. The following two kinds of setting mode of connection part 33 are described in detail.

[0190] In the case of the connection part 33 being set in the cosmetic instrument body 1, the cosmetic instrument body 1 is detachably connected with the container 61 through the connection part 33, and the container 61 is communicated with the negative pressure channel 4 through the connection part 33. The specific structure of the connection part 33 is the same as the above structure setting mode, which will not be repeated here.

[0191] In the case of the connection part 33 being set in the main body 32, as shown in Figure 10, the connection part 33 is different from the above-mentioned connection part 33 in the setting position, and other structure settings are the same as the above-mentioned connection part 33, which will not be repeated here. In the setting mode of the present embodiment, the connection part 33 is set in the main body 32, rather than being set on the cosmetic instrument body 1 as described above. Specifically, the connection part 33 is connected with or integrally formed with the main body 32. Furthermore, the main body 32 is also provided with the above-mentioned negative pressure channel 4. When the container 61 is connected to the main body 32 through the connection part 33, the container 61 is communicated with the negative pressure channel 4, realizing the liquid outlet function.

[0192] Further, referring to Figure 13, the main body 32 is provided with a positioning recess 333, which is the above-mentioned bottle mouth slot 339. The positioning recess 333 has a bottom wall and a side wall connected with the bottom wall, the insertion part 330 is arranged on the bottom wall, and the side wall is provided with a limiting part. It needs to be explained that the limiting part is the above-mentioned slot wall boss 338, of course, the structure of the above-mentioned slot wall boss 338 can also be replaced by other limiting modes described below. In some embodiments, the limiting part can be arranged as the surface of the side wall, and the extension profile of the entire side wall is adapted to the outer peripheral profile of the container 61. At this time, the limiting part can abut against the peripheral side of the container 61 when the container 61 is connected with the insertion part, which can play the effect of assembling and positioning the container 61, so that the container 61 can be more quickly and accurately connected with the connection part 33, and the use experience is further optimized and improved.

[0193] It needs to be explained that the limiting part can also be a sliding limiting structure such as a slider and a sliding rail, and any structure that can realize the guiding function when the container 61 is connected with the connection part 33 can be tried to be used, which will not be limited here.

[0194] It can be understood that in the embodiment in which the connecting portion 33 is arranged on the main body 32, when the main body 32 is arranged inside the cosmetic instrument body 1, referring to FIG. 13, here, when the main body 32 is arranged inside the cosmetic body, a first avoiding opening 101 is arranged on one side of the cosmetic instrument body 1, the first avoiding opening 101 penetrates through the inside and outside of the cosmetic instrument body 1, the arrangement position of the first avoiding opening 101 corresponds to the connecting portion 33 on the main body 32, and the first avoiding opening 101 can expose the connecting portion 33 for dismounting the container 61.

[0195] By mounting the container 61 into the connecting portion 33 from outside to inside, part of the container 61 can be left outside the cosmetic instrument body 1, which facilitates the user to dismount the container 61, and when the container 61 is made of transparent material, the user can also observe the remaining amount of the essence liquid, so that the user can selectively replace the container 61 regularly, reduce the problem of bacterial growth caused by long-term residual of the essence liquid, and make the skin care environment cleaner and more hygienic.

[0196] [About the cosmetic instrument body 1]

[0197] The liquid storage cavity 6 has various different arrangement modes, and the cosmetic instrument body 1 is correspondingly arranged with a structure for adding or replacing the essence liquid container 61 corresponding to each arrangement mode of the liquid storage cavity 6.

[0198] In some embodiments, in the arrangement mode in which the liquid storage cavity 6 is arranged inside the cosmetic instrument body 1, an opening for supplementing the addition of the essence liquid is correspondingly arranged on the cosmetic instrument body 1; in the arrangement mode in which the container 61 is arranged outside the cosmetic instrument body 1, a first avoiding opening 101 for dismounting the container 61 is correspondingly arranged on the cosmetic instrument body 1.

[0199] Because of the above arrangement, foreign matters such as dust from outside are easy to enter the liquid storage cavity 6 from the opening or the first avoiding opening 101, and pollute the subsequent added essence liquid. In order to improve the hygiene and safety of the cosmetic care environment, the cosmetic instrument further comprises a sliding cover 13 for shielding the above opening or the first avoiding opening 101. Hereinafter, the sliding cover 13 for shielding the first avoiding opening 101 will be taken as an example for specific description, and the arrangement of the sliding cover 13 for shielding the opening is the same as the following description, which will not be repeated here.

[0200] Referring to FIG. 15, the surface of the cosmetic instrument body 1 is further provided with a first avoiding opening 101 for exposing the connecting portion 33, and the cosmetic instrument further comprises a sliding cover 13 which is in sliding connection with the cosmetic instrument body 1. The sliding cover 13 has a closing state of sliding to cover relative to the cosmetic instrument body 1, and has an opening state of sliding to open the first avoiding opening 101 relative to the cosmetic instrument body 1.

[0201] When the container 61 needs to be installed, the sliding cover 13 is slid to the open cover state, so that the first avoiding port 101 is exposed, and then the container 61 can be inserted into the first avoiding port 101; after the container 61 is taken out, the sliding cover 13 is slid to the closed cover state, so that the first avoiding port 101 is covered, that is, the problem that dust and other foreign matters enter the first avoiding port 101 can be avoided. The arrangement of the sliding cover 13 can effectively solve the problem that dust and other foreign matters in the outside environment easily enter the beauty instrument through the installation position of the container 61, and guarantee the sanitary safety of the beauty care environment.

[0202] In conclusion, the beauty instrument and the beauty kit provided by the embodiment have the following advantages: through the design of the sliding connection between the sliding cover 13 and the beauty instrument body 1, the installation position (that is, the first avoiding port 101 and the connecting portion 33) of the container 61 can be completely covered after the container 61 is pulled out, so that dust and other foreign matters can be effectively prevented from entering the beauty instrument, and the cleanliness of the beauty instrument can be maintained.

[0203] In some embodiments, when the main body piece 32 is detachably installed in the beauty instrument body 1 and the container 61 is detachably connected to the main body piece 32, the problem that the delivery component of the essence liquid cannot be cleaned or replaced can be solved. The detachable structure of the main body piece 32 and the container 61 will be described below.

[0204] In one embodiment, please refer to FIGS. 2, 3 and 10, the installation port 102 is located at the end surface of the beauty instrument body 1, the first avoiding port 101 is located at the circumferential surface of the beauty instrument body 1, and the installation port 102 and the first avoiding port 101 are in communication with each other through the internal space of the beauty instrument body 1. The main body piece 32 is plug-in connected with the beauty instrument body 1 through the installation port 102, and the container 1 is plug-in connected with the main body piece 32 through the first avoiding port 201, so as to connect the liquid outlet flow channel 1004 (that is, the first negative pressure pipeline 41) in the main body piece 3.

The main body bottom box 32a is provided with a main body inner cavity 32a1 with an opening, and the liquid outlet flow channel 1004 is located in the main body inner cavity 32a1. Further, the size of the opening of the main body inner cavity 32a1 is larger than the size of the liquid outlet flow channel 1004, so that the liquid outlet flow channel 1004 can enter and exit the main body inner cavity 32a1 through the opening of the main body inner cavity 32a1. The main body top cover 32b is detachably connected to the main body bottom box 32a, and is used to cover the opening of the main body inner cavity 32a1. Optionally, the main body bottom box 32a and the main body top cover 32b are magnetically connected and / or snap connected, so that the user can easily open the main body top cover 32b without using a screwdriver or other tools, and take out the liquid outlet flow channel 1004 through the opening of the main body inner cavity 32a1 and clean it.

Correspondingly, the inside of the beauty instrument body 1 is provided with a second communication part 112 corresponding to the position of the first communication part 111 for conveying gas to the first communication part 111 and pluggably connected with the first communication part 111. Further, the position where the first communication part 111 is inserted into the second communication part 112 is provided with an air inlet sealing ring 113.

[0211] ②The detachable structure of the snap connection or magnetic attraction between the main body bottom box 32a and the main body top cover 32b makes it easy for the user to open the main body bottom box 32a, take out the liquid outlet flow channel 1004 and maintain and clean it, thereby enhancing the maintainability of the equipment;

[0212] ③By providing the first communication part 111, the second communication part 112 and the air inlet sealing ring 113, the detachable design of the main body 32 is realized, and the sealing and stability of gas delivery are also ensured, so that the essence liquid can be uniformly and effectively pushed out to the beauty head 31.

[0213] [About the beauty head 31 and the negative pressure cavity 2]

[0214] The setting mode of the beauty head 31 has multiple modes. One of the setting modes of the beauty head 31 is fixed setting. In the specific installation, the beauty head 31 can be fixedly installed on the beauty instrument body 1, and the beauty instrument body 1 provides a supporting effect for the beauty head 31. Or as shown in FIG. 13, the beauty head 31 can also be fixedly installed on the main body piece 32. At this time, the beauty head 31 and the main body piece 32 form a modular structure to facilitate one-time production.

[0215] The second setting mode of the beauty head 31 is detachable setting. For example, the beauty head 31 is detachably connected with the main body piece 32 through a connecting structure (such as a buckle structure, a threaded structure, etc.), or the beauty head 31 is detachably connected with the beauty instrument body 1. At this time, the beauty head 31 can be individually detached and replaced, which is beneficial to maintaining the hygiene of the beauty head 31 and optimizing the skin care environment. It should be noted that the specific setting mode of the beauty head 31 can be adjusted according to actual needs, and is not limited here. No matter what installation mode the beauty head 31 adopts, as long as any one of the above-mentioned solutions is adopted, it should be included in the consideration range of the alternative means of the present solution.

[0216] The following will be described in detail taking the fixed setting mode of the beauty head 31 as an example. Please refer to FIG. 13. The beauty head 31 is arranged on the main body piece 32, and the beauty head 31 is fixedly connected with the main body piece 32. In this way, the integrated production of the main body piece 32 and the beauty head 31 can be realized. For the convenience of description, the main body piece 32 and the beauty head 31 form a beauty assembly 3 that can be integrated and produced. Through the fixed installation mode, the structure of the beauty assembly 3 is stable and is not easy to fall off.

[0217] Referring to FIG. 16, to further prevent the essence from flowing back into the second section of the negative pressure channel 4, the present embodiment sets an anti-backflow structure at the beauty head 31. Specifically, the anti-backflow structure realizes the anti-backflow function by prolonging the path of the airflow in the negative pressure cavity 2. In the present embodiment, the negative pressure cavity 2 includes an outer cavity portion 21 and an inner cavity portion 22.

[0218] In some embodiments, referring to FIG. 16, the cosmetic head 31 comprises a core 31a and a suction sleeve 31b. The core 31a is connected to the main body 32, the core 31a is hollow inside, and the core 31a forms the inner cavity 22 inside. The suction sleeve 31b is sleeved on the outside of the core 31a. The cosmetic assembly 3 further comprises a sealing ring 7 connected to the suction sleeve 31b and the core 31a, thereby forming the outer cavity 21 between the core 31a and the suction sleeve 31b. One side of the suction sleeve 31b has an open structure, which can communicate the outer cavity 21 with the outside. The core 31a is further provided with an internal and external communication hole 1001, which can communicate the outer cavity 21 with the inner cavity 22. The inner cavity 22 communicates with the second section of the negative pressure channel 4. The airflow needs to flow through the outer cavity 21, the internal and external communication hole 1001, and the inner cavity before reaching the second section of the negative pressure channel 4, which prolongs the path of the airflow in the negative pressure cavity 2, which is conducive to reducing the possibility of the essence being sucked into the second section of the negative pressure channel 4 after being output from the cosmetic head 31.

[0219] Continuing to refer to FIG. 16, specifically, based on the first negative pressure pipeline 41 and the second negative pressure pipeline 42 described above, the negative pressure channel 4 comprises a first section and a second section. The first section is used to communicate the liquid storage cavity 6 and the outer cavity 21. Specifically, when the liquid storage cavity 6 and the outer cavity 21 are communicated, one end of the first negative pressure pipeline 41 is connected to the connecting part 33, and the other end is directly connected to the core 31a. The core 31a is provided with a core pipe 8, one end of the core pipe 8 is connected to the first section, and the other end of the core pipe 8 communicates with the outer cavity 21, thereby realizing the communication between the liquid storage cavity 6 and the outer cavity 21. The second section is used to communicate the inner cavity 22 and the negative pressure mechanism 5. Specifically, one end of the second negative pressure pipeline 42 is connected to the negative pressure mechanism 5, and the other end is directly connected to the core 31a. The core 31a is provided with an interface for airflow, and the second negative pressure pipeline 42 is communicated with the inner cavity 22 through the interface.

[0220] Through the above arrangement, the negative pressure mechanism 5 is started, and the negative pressure mechanism 5 can form a negative pressure at the inner cavity through the negative pressure channel 4. At this time, under the action of the through hole, the outer cavity 21 is also formed with a negative pressure. At this time, because the outer cavity 21 communicates with the outside, when the cosmetic head 31 contacts the skin, the outer cavity 21 will adsorb the skin, and the suction sleeve 31b in the form of a sleeve structure can well form a negative pressure area on the surface of the skin, and the adsorption action is fast and efficient. At the same time, because the outer cavity 21 has a negative pressure, the negative pressure channel 4 will suck the essence to the outer cavity 21, so that the essence can be attached to the suction element 3123 and then applied to the skin. The arrangement of the outer cavity 21, the internal and external communication hole 1001, and the inner cavity prolongs the path of the airflow. In this process, the essence overflowing from the suction element 3123 will be attached to the inner wall of the negative pressure cavity 2 during the movement of the airflow, thereby achieving a certain anti-backflow effect.

[0221] Specifically, referring to FIG. 16, the core body 31a comprises a core seat 311, one side of the core seat 311 is connected with the main body 32, and the inside of the core seat 311 is hollow to form the inner cavity 22. Specifically, the core seat 311 is a sleeve structure with one end closed, and the closed end of the core seat 311 is connected with the main body 32 and is provided with the aforementioned interface in communication with the second negative pressure pipeline 42.

[0222] The core pipe 8 comprises a pipe head 81 and a pipe body 82, the pipe head 81 closes the open end of the core seat 311 to form the inner cavity 22 in the internal space of the core seat 311 (i.e. the pipe head 81 covers the opening of the inner cavity 22), and the pipe body 82 extends from one side of the pipe head 81 towards the inner cavity 22 and penetrates the closed end of the core seat 311 to be connected with the first negative pressure pipeline 41. The core seat 311 is provided with a pipe penetrating hole 1007, and the pipe body 82 communicates the first negative pressure pipeline 41 and the outer cavity 21 through the pipe penetrating hole 1007.

[0223] The inner-outer communication hole 1001 connecting the outer cavity 21 and the inner cavity 22 is formed in the core seat 311 and located on the side close to the closed end of the core seat 311, i.e. the side close to the main body 32. This arrangement can prolong the distance between the inner-outer communication hole 1001 and the opening, thereby prolonging the flow path of the air flow in the outer cavity 21. In addition, the core seat 311 is further provided with an extension pipe 313, the extension pipe 313 extends into the inner cavity 22 at the interface connected with the second negative pressure pipeline 42 to communicate the negative pressure mechanism 5 with the inner cavity 22, and the end of the extension pipe 313 extending into the inner cavity is located on the side away from the inner-outer communication hole 1001.

[0224] In this way, the flow path of the air flow in the inner cavity 22 can be further prolonged, and the outer cavity 21, the inner-outer communication hole 1001 and the inner cavity 22 form a flow path with multiple bends, thereby prolonging the flow path of the air flow in the entire outer cavity 21 and the entire inner cavity 22, and the path drives the air flow and the essence liquid overflowing from the adsorption element 3123 to bend multiple times, more essence liquid flowing with the air flow will adhere to the inner wall of the negative pressure cavity 2 at the bending position due to inertia, thereby further improving the anti-backflow effect.

[0225] Further, referring to FIG. 17, in order to realize the application action of the essence liquid, in one embodiment, the adsorption element 3123 is installed on the core body 31a, the adsorption element 3123 is located in the outer cavity 21 and is located on the outermost side of the core body 31a, the core body 31a is connected with the first section of the negative pressure channel 4, and the essence liquid can flow from the first section of the negative pressure channel 4 and the core pipe 8 directly into the adsorption element 3123.

[0226] Optionally, the adsorption element 3123 can be a sponge block, a porous silica gel block, or a porous ceramic block, etc. These materials have a strong liquid absorption capacity due to their porous structure. They can absorb and retain a large amount of essence, so that the essence can be more uniform and continuous during delivery, and the use effect will not be affected by the instantaneous flow change.

[0227] In some embodiments, the adsorption element 3123 adopts a structure with elasticity, such as a liquid storage sponge or a porous silica gel block, etc. The material is soft, friendly to the skin, and more comfortable to use. The user can directly contact the sponge or porous silica gel block with the skin to realize the liquid output function of the beauty head 31. In this embodiment, a sponge structure is adopted. The sponge has good liquid storage function and good rebound performance, and can provide a good experience for the user when directly contacting the skin to apply the essence.

[0228] Alternatively, in some other embodiments, to realize the liquid storage function, the adsorption element 3123 can also be provided with a cavity for storing essence in the core body 31a. Specifically, the cavity in the core body 31a is directly communicated with the core pipe 8, and the liquid outlet 1002 is arranged on the core body 31a and communicated with the cavity. When the liquid in the cavity is full, the liquid will flow out from the liquid outlet 1002, so that the liquid storage effect can also be realized. Therefore, the cavity can also be regarded as the adsorption element 3123. In this embodiment, the cavity for storing essence is directly formed in the core body 31a, which helps to control the production and assembly cost, improve the production efficiency, and is also convenient for cleaning and improves the hygiene safety.

[0229] Further, referring to FIG. 18, to optimize the liquid output effect, in one embodiment, the core body 31a further includes an application unit 3121. The application unit 3121 is in a sleeve structure, and the application unit 3121 is movably sleeved on the other side of the core seat 311. The application unit 3121 is located on the side of the core body 31a close to the skin, i.e. the outermost side, and the application unit 3121 is provided with a liquid outlet 1002 communicated with the pipe hole 1007 of the core seat 311.

[0230] Moreover, the adsorption element 3123 is arranged between the core seat 311 and the application unit 3121. Since the adsorption element 3123 is an elastic structure, the application unit 3121 and the core seat 311 of the core body 31a can extrude the adsorption element 3123 to send the essence out of the liquid outlet 1002 to the skin. Through this arrangement, the pressing force can be changed during use to control the liquid output, and the use is more flexible and convenient.

[0231] Further, with continuous reference to FIG. 16, the core 31a further comprises an elastic member 314, preferably a spring structure, and the elastic member 314 is located between the core seat 311 and the application unit 3121, specifically, the two ends of the elastic member 314 can be fixedly connected with the core seat 311 and the application unit 3121 respectively, the adsorption element 3123 is sleeved in the elastic member 314 or arranged side by side with the elastic member 314, and the elastic member 314 can provide elastic buffering for the core seat 311 and the application unit 3121, so that the structure can quickly rebound and reset, and the convenience of use and the skin experience are optimized and improved.

[0232] Further, in order to promote the absorption of the essence, the application unit 3121 is further provided with micro-needles, specifically, referring to FIG. 16, the micro-needle wafer 3122 can be installed on the outermost side of the application unit 3121, or the nano-micro-needle structure is directly formed on the application unit 3121, that is, the application unit 3121 itself is a micro-needle wafer 3122. Through the above-mentioned setting, the nano-micro-needles on the application unit 3121 or the micro-needle wafer 3122 can form micro-channels on the skin by stimulating the skin, thereby promoting the absorption of the essence.

[0233] In the specific setting, the liquid outlet 1002 is arranged on the micro-needle wafer 3122, the micro-needle wafer 3122 is connected to the main body member 32 and located at the outermost side of the beauty head 31, the adsorption element 3123 is connected to the main body member 32 and located between the micro-needle wafer 3122 and the main body member 32. In this setting, the micro-needle wafer 3122 is indirectly arranged on the main body member 32 through the adsorption element 3123, and one side of the adsorption element 3123 is connected to the first section of the negative pressure channel 4, and the other side is connected to the liquid outlet 1002, at this time, the first section of the negative pressure channel 4 and the liquid outlet 1002 are communicated.

[0234] It can be understood that in the mode of installing the micro-needle wafer 3122 on the outermost side of the application unit 3121, the application unit 3121 is provided with a flow hole corresponding to the liquid outlet 1002 on the micro-needle wafer 3122, so that the essence can be smoothly transmitted from the adsorption element 3123 to the liquid outlet 1002.

[0235] Through the above-mentioned setting, the essence can directly flow into the adsorption element 3123, the micro-needle wafer 3122 can stimulate the skin due to being located at the outermost side of the beauty head 31, and in this process, the micro-needle wafer 3122 can extrude the adsorption element 3123, so that the essence flows out from the liquid outlet 1002, and the essence is coated at the same time, which facilitates the essence to penetrate into the skin from the micro-channels formed by the micro-needle wafer 3122, thereby improving the absorption of the essence.

[0236] In addition, the setting position of the liquid outlet 1002 can also not be on the microneedle wafer 3122. Specifically, the microneedle wafer 3122 and the adsorption element 3123 are connected to and arranged adjacent to the main body 32, the adsorption element 3123 is connected to the first section of the negative pressure channel 4, and at this time, the porous structure of the adsorption element 3123 forms the liquid outlet 1002.

[0237] [Optimization of essence application]

[0238] In the above-mentioned manner of applying essence through the adsorption element 3123 or the application unit 3121, the adsorption element 3123 or the application unit 3121 contacts the skin only after the adsorption sleeve 31b contacts the skin and forms a negative pressure area, thereby applying essence to the skin. This way, the amount of essence applied is small, and there is also the problem of unevenness. In order to make the application of essence more uniform, more permeable, and optimize the use experience of the beauty instrument, the beauty instrument of the embodiment further comprises a vibration mechanism 9 for driving the beauty head 31 to reciprocate.

[0239] Referring to FIGS. 3, 19 and 20, in an embodiment, the vibration mechanism 9 is arranged in the beauty instrument body 1 and comprises a vibration motor 91, which is in transmission connection with the beauty head 31 to drive the beauty head 31 to reciprocate, so that the beauty instrument can not only stably apply essence, but also massage the skin to promote the absorption of essence, with strong application accuracy and uniform application effect, thereby improving the use experience. Especially when the beauty head 31 is provided with the microneedle wafer 3122, the vibration mechanism 9 applies regular and emphasized vibration to the beauty head 31, which helps to form skin microchannels with uniform depth on the skin and increase the uniformity of essence penetration. Alternatively, the vibration motor 91 can be an eccentric vibration motor 91, which has the functions of compact size and stable vibration, and well meets the required working conditions.

[0240] In another embodiment, the beauty head 31 can also be directly connected to the vibration motor 91, that is, the beauty head 31 can be directly connected to the vibration motor 91 without arranging the main body 32, which has a simple structure and low manufacturing cost. In this embodiment, in order to realize the functions of vibration and negative pressure adsorption for applying essence, the negative pressure channel 4 can be arranged as a hose. In addition, the beauty head 31 can be detachably connected to the vibration motor 91 to facilitate replacement of the beauty head 31.

[0241] Please continue to refer to FIG. 19 and FIG. 20, and the following embodiment is taken as an example that the cosmetic head 31 is drivingly connected with the main body 32 and the vibration mechanism 9. In the embodiment, the cosmetic head 31 is connected to one end of the main body 32, and the vibration motor 91 is drivingly connected to the other end of the main body 32, and the vibration motor 91 can drive the main body 32 to reciprocate the cosmetic head 31. Through the setting, the whole cosmetic assembly 3 can be driven by the vibration mechanism 9, and the negative pressure channel 4 can be integrated on the main body 32 while meeting the vibration function, and further considering the compactness of the structure. It can be understood that, in order to consider the realization of the vibration and the negative pressure adsorption and application of essence function, the negative pressure channel 4 is connected with the negative pressure mechanism 5 through a hose.

[0242] In the embodiment, the connection of the vibration mechanism 9 and the main body 32 can have two setting modes. One is that the main body 32 is fixedly arranged on the vibration mechanism 9, and the advantage of such setting is that the connection mode of the main body 32 is simple, and the structure is relatively firm; the other is that the main body 32 is detachably arranged on the vibration mechanism 9, and such setting sets the main body 32 as a consumable, and the negative pressure channel 4 conveying essence can be replaced in the form of the main body 32, so as to improve the sanitary safety.

[0243] In some embodiments, when the main body 32 is detachably arranged on the vibration mechanism 9, the vibration mechanism 9 can further include a vibration connecting piece 92, the vibration connecting piece 92 is in a sleeve structure, and the main body 32 is detachably connected to the vibration connecting piece 92; wherein one side of the vibration connecting piece 92 is open, and the opening contour and size are matched with the main body 32, at this time, the main body 32 can be plug-in installed on the vibration connecting piece 92, and the structure positioning is realized, so as to facilitate the detachable connection.

[0244] At the same time, the vibration connecting piece 92 is drivingly connected with the vibration motor 91, specifically, a transmission rod is further arranged on the vibration connecting piece 92, the vibration connecting piece 92 is connected with the output shaft of the vibration motor 91 through the transmission rod, and the peripheral side of the vibration connecting piece 92 is in sliding abutment with the inner peripheral wall of the cosmetic instrument body 1, so that the vibration connecting piece 92 can reciprocate in the cosmetic instrument body 1, and when the vibration occurs, the main body 32 and the cosmetic head 31 also reciprocate along the length direction of the cosmetic instrument body 1.

[0245] In addition, in the arrangement of the cosmetic kit using the container 61 to store the essence, the vibration connecting piece 92 of the cosmetic device is further provided with a second avoiding port 921 for exposing the connecting part 33 of the main body piece 32 for the dismounting of the container 61. In the above arrangement, the vibration motor 91 can drive the vibration connecting piece 92 to reciprocate, and meanwhile, the dismounting and mounting of the container 61 can be satisfied. More importantly, the user can dismount the whole main body piece 32, and at this time, the liquid can be avoided to remain in the negative pressure channel 4 of the main body piece 32, i.e. the liquid can be avoided to remain in the first negative pressure pipeline 41 and the second negative pressure pipeline 42, so as to reduce the possibility of bacterial breeding, and the safety and health can be ensured.

[0246] It should be explained that the vibration connecting piece 92 can be arranged outside the cosmetic device body 1, and at this time, the second avoiding port 921 can be arranged to expose the connecting part 33. However, in order to satisfy the requirements of stable and compact structure, referring to Fig. 19 and combining with Fig. 2, in the scheme shown in the embodiment, the vibration connecting piece 92 is arranged in the cosmetic device body 1, wherein one end of the cosmetic device body 1 is provided with a mounting port 102 for the dismounting of the main body piece 32. The mounting port 102 can enable the cosmetic assembly 3 to be mounted to the inside of the cosmetic device body 1, and can play an avoiding role and be used for the dismounting of the cosmetic assembly 3. Correspondingly, the first avoiding port 101 and the second avoiding port 921 of one side of the cosmetic device body 1 correspond to each other, and the container 61 can be sequentially connected with the connecting part 33 through the first avoiding port 101 and the second avoiding port 921.

[0247] In addition, the length of the first avoiding port 101 in the vibration direction of the main body piece 32 is greater than the length of the second avoiding port 921 in the vibration direction of the main body piece 32, so as to avoid the vibration interference between the container 61 and the cosmetic device body 1 when the container 61 vibrates with the cosmetic assembly 3.

[0248] Referring to Fig. 20, in the case of the dismounting connection between the main body piece 32 and the vibration mechanism 9, the connection between the negative pressure channel 4 and the negative pressure mechanism 5 also needs to be ensured, so as to avoid the problem of air leakage in the dismounting process. Specifically, in the embodiment, the vibration connecting piece 92 is provided with the aforementioned communication part 11, the communication part 11 is in a column pipe structure, both ends of the communication part 11 extend to the outside and the inside of the vibration connecting piece 92, and meanwhile, the hollow part of the communication part 11 forms a connection channel, and the negative pressure mechanism 5 communicates with the negative pressure channel 4 through the communication part 11.

[0253] [Refined arrangement of the beauty head 31]

[0254] Further, with reference to FIG. 22, based on the above structure, some embodiments can obtain a beauty head 31 and a beauty instrument for further optimizing the uniform liquid delivery effect of the beauty head 31.

[0255] The following first introduces the use process of the beauty instrument taking the storage of the essence liquid in the container 61 as an example:

[0256] S10: The beauty instrument is close to the human skin, so that the human skin blocks the opening of the outer cavity portion 21; then, the negative pressure mechanism 5 performs negative pressure extraction on the outer cavity portion 21, so that the air pressure of the outer cavity portion 21 is lowered to be lower than the internal air pressure of the container 61, and then under the action of the pressure difference, the essence liquid in the container 61 is delivered to the beauty head 31 through the liquid outlet flow channel 1004 and is delivered to the human skin through the liquid outlet 1002 of the beauty head 31;

[0257] S20: The vibration mechanism 9 drives the beauty head 31 to perform forward and backward micro-distance vibration, and the beauty head 31 will continuously stimulate the human skin and promote the absorption of the essence liquid by the human skin during the vibration process;

[0258] Optionally, the vibration mechanism 9 is a cam connecting rod mechanism, or the vibration mechanism 9 is a linear driving mechanism, etc., which are not limited in the embodiment. Further, the linear driving mechanism can be a gas cylinder, a hydraulic cylinder, an electric cylinder or a motor screw rod linear module, etc.

[0259] At this point, in order to optimize the beauty effect of the beauty head 31, the following further introduces the beauty head 31 in the embodiment in detail.

[0260] With reference to FIG. 23, the beauty head 31 provided by the embodiment includes a core pipe 8, a liquid outlet component 312 and a suction element 3123. The core pipe 8 is provided with a pipe-in liquid delivery hole 821. The liquid outlet component 312 is connected with the core pipe 8 and cooperates with the core pipe 8 to surround a closed buffer cavity 1006; wherein the liquid outlet component 312 is provided with a liquid outlet 1002 which communicates the buffer cavity 1006 to the external space of the beauty head 31. The suction element 3123 is a porous structure, and the suction element 3123 is located in the buffer cavity 1006.

[0261] The cosmetic head 31 and the cosmetic instrument provided by the embodiments of the present application can ensure that the flow of the essence liquid delivered outward through the liquid outlet is relatively stable, and thus avoid the problem of uneven or discontinuous delivery of the essence liquid caused by the fluctuation of the supply amount of the essence liquid delivered through the liquid delivery hole in the tube.

[0262] On the other hand, when the negative pressure mechanism 5 performs negative pressure suction on the outer cavity portion 21, the adsorption element 3123 can buffer the essence liquid in the buffer cavity 1006, control the liquid outlet amount of the liquid outlet 1002, and avoid the direct flow of a large amount of essence liquid through the liquid outlet 1002, so as to avoid the waste of the essence liquid caused by the direct negative pressure suction of the outer cavity portion 21 by the negative pressure mechanism 5.

[0263] Optionally, the core tube 8 and the liquid outlet component 312 are in sliding sealing connection, and the buffer cavity 1006 is further provided with springs 3141 abutting against the core tube 8 and the liquid outlet component 312, respectively; wherein the springs 3141 are used to drive the liquid outlet component 312 to move away from the adsorption element 3123.

[0264] The design of the springs 3141 enables the cosmetic head 31 to automatically adjust the liquid outlet amount according to the pressure of the skin contact. Specifically, the springs 3141 are used to balance the internal and external pressures, and when the external pressure decreases, the springs 3141 push the liquid outlet component 312 to reduce the liquid outlet amount, and vice versa. In this way, the stable delivery of the essence liquid can be ensured, and the influence of the user's operation force can be avoided.

[0265] Optionally, the number of the springs 3141 is one, and the adsorption element 3123 is located in the hollow space of the spring 3141. When the number of the springs 3141 is one, the adsorption element 3123 is located in the hollow space of the spring 3141, and such a layout can effectively utilize the space and improve the compactness of the cosmetic head 31.

[0266] Alternatively, the number of springs 3141 is at least two, each spring 3141 is uniformly arranged around the adsorption element 3123, for example, the number of springs 3141 is two, the two springs 3141 are symmetrically arranged about the adsorption element 3123; or the number of springs 3141 is three, the three springs 3141 are arranged in a regular triangle, and the adsorption element 3123 is located at the center of the regular triangle; or the number of springs 3141 is four, the four springs 3141 are arranged in a square, and the adsorption element 3123 is located at the center of the square, etc. The uniform arrangement of multiple springs 3141 can provide more stable support and pressure balance, and ensure uniform output of the essence liquid.

[0267] In some embodiments, the cosmetic head 31 further comprises a seat 311. The seat 311 is provided with an inner cavity portion with an opening facing the adsorption element 3123, an extension pipe 313 communicating the inner cavity portion with the negative pressure mechanism 5, an inner-outer communication hole 1001 communicating the inner cavity portion with the outer cavity portion 21, and a pipe-through hole 1007 communicating the inner cavity portion with the external space of the seat 311.

[0268] Correspondingly, the core pipe 8 comprises a pipe head 81 and a pipe body 82. The pipe head 81 is sleeved on the seat 311 to cover the opening of the inner cavity portion 22; one end of the pipe body 82 is fixedly connected to the pipe head 81 and communicates with the buffer cavity 1006, and the other end extends to the external space of the inner cavity portion 22 through the pipe-through hole 1007 to be connected with the liquid outlet flow channel 1004. The liquid-in pipe hole 821 is located in the pipe body 82.

[0269] When the negative pressure mechanism 5 performs air suction, the air in the outer cavity portion 21 is sequentially sucked into the negative pressure mechanism 5 through the inner-outer communication hole 1001, the inner cavity portion 22, and the extension pipe 313, thereby realizing the negative pressure suction process of the outer cavity portion 21; after the internal air pressure of the outer cavity portion 21 decreases, the essence liquid in the container 61 can be transported to the adsorption element 3123 of the buffer cavity 1006 through the liquid outlet flow channel 1004 and the liquid-in pipe hole 821.

[0270] In some embodiments, the liquid outlet component 312 comprises an application unit 3121 provided with an open slot, and a microneedle wafer 3122 located on the side of the application unit 3121 away from the adsorption element 3123; wherein the application unit 3121 is provided with a unit through hole 3124 communicating with the buffer cavity 1006, and the liquid outlet 1002 is located on the microneedle wafer 3122 and communicates with the unit through hole 3124.

[0271] The head of the core pipe 8 is inserted into the open slot, wherein the core pipe 8, the slot wall of the open slot, and the slot bottom of the open slot surround to form the buffer cavity 1006. Further, the circumferential surface of the head of the core pipe 8 is sleeved with a sealing piece 315 abutting against the slot wall of the open slot.

[0272] The open slot design allows the core tube 8 to be inserted and form a buffer cavity 1006, which facilitates assembly and maintenance. When the vibration mechanism 9 drives the application unit 3121 to repeatedly vibrate and press the human skin, the microneedle wafer 3122 can help the essence penetrate the skin more deeply through the fine needle holes.

[0273] Optionally, the circumferential surface of the head of the core tube 8 is provided with a tube peripheral boss 811, and the slot wall of the open slot is provided with a slot wall limiting boss 3125; wherein the slot wall limiting boss 3125 abuts against the surface of the tube peripheral boss 811 away from the adsorption element 3123, so as to limit the core tube 8 from being separated from the application unit 3121 through the slot of the open slot. Through the cooperation of the tube peripheral boss 811 and the slot wall limiting boss 3125, the movement of the core tube 8 relative to the liquid outlet component 312 is limited, the relative position between the two is ensured to be stable, and the stability of the essence delivery is ensured.

[0274] In summary, the cosmetic head 31 and the cosmetic instrument provided by the embodiment of the present application have the following advantages after being combined with the vibration mechanism 9:

[0275] ①The adsorption element 3123 with a porous structure can not only buffer the essence, adjust the speed and amount of the essence flowing out of the liquid outlet 1002, and thus ensure the uniformity and stability of the essence delivery, but also control the amount of liquid in a negative pressure environment, prevent the essence from being sucked by the negative pressure mechanism 5, and reduce waste;

[0276] ②The design of the spring 3141 enables the cosmetic head 31 to automatically adjust the amount of liquid according to the skin contact pressure, and ensures the stable delivery of the essence;

[0277] ③The core seat 311, the core tube 8, and the liquid outlet component 312 are sequentially plugged, which is simple and convenient to disassemble and assemble, and is convenient for assembly and maintenance.

[0278] [Sealing arrangement of the negative pressure cavity 2]

[0279] After the cosmetic instrument is provided with the vibration mechanism 9 and the cosmetic assembly 3, because the negative pressure cavity 2 needs to be formed, and vibration is easy to cause the negative pressure cavity 2 to leak, therefore, the embodiment further discloses a sealing scheme, which can meet the effect of stable adsorption under the condition of vibration.

[0280] Referring to FIG. 24, in this cosmetic instrument scheme, a core body 31a, an adsorption sleeve 31b, and a sealing ring 7 are included. The core body 31a is used to be connected with the vibration mechanism 9 (not marked in the figure), and the vibration mechanism 9 can drive the core body 31a to reciprocate, so as to play the effect of vibration massage. The specific structure of the core body 31a can be adjusted according to actual needs, and will not be described here. In order to realize the adsorption function, the core body 31a includes a negative suction channel for gas transmission. It can be understood that the negative suction channel can be composed of the extension pipe 313 and the inner cavity part 22 mentioned above, and the specific arrangement mode will not be described here.

[0281] The core 31a is arranged in the adsorption sleeve 31b, a negative pressure cavity 2 in communication with the negative suction channel is formed between the core 31a and the adsorption sleeve 31b, and the negative pressure cavity 2 is used for communication with the negative pressure mechanism 5 through the negative suction channel, at this time, the airflow can flow into the negative pressure mechanism 5 through the negative suction channel, and then a negative pressure area capable of adsorbing the skin is formed in the negative pressure cavity 2.

[0282] It can be understood that, in order to obtain appropriate adsorption force, the air pressure of the negative pressure area is preferably controlled in the range of-20kpa to-40kpa, and the specific value can be-20kpa, -30kpa or-40kpa, etc., and the air pressure of the negative pressure area can be set based on the skin feeling and specific adsorption requirements; among them, for the sensitive skin users, the air pressure of-20kpa can be used for adsorption, so that smaller adsorption force can be obtained, and it is not easy to cause skin marks, so as to avoid red and itchy phenomenon; under the condition of-30kpa, the adsorption force is moderate, which is suitable for most users' skin quality, and when the air pressure is-40kpa, larger adsorption force can be provided, which is suitable for users who can tolerate large suction force and are easy to have position deviation in the use process, such as oily skin users. Therefore, by controlling the air pressure in the range of-20kpa to-40kpa, the user can obtain good experience, and the specific value of the air pressure can be adjusted according to the actual design, which is not limited here.

[0283] Further, in the negative pressure adsorption process, in order to further improve the overall skin feeling of the skin, the thickness of the adsorption sleeve 31b can be set to be between 0.8-2.8mm, such as 0.8mm, 1.4mm or 2.8mm, etc., and a chamfer can also be arranged on the edge of the adsorption sleeve 31b, and the range of the chamfer is between 0.3mm-0.8mm, and 0.3mm, 0.5mm or 0.8mm, etc. can be selected.

[0284] Optionally, the thickness of the adsorption sleeve 31b can be set according to the skin quality requirements, such as 2.8mm for sensitive skin users, which can reduce the pressure on the skin during adsorption by increasing the thickness, so that the skin is not easy to swell and itch, in addition, the adsorption sleeve 31b with a thickness of 1.4mm can be suitable for most neutral skin, which is suitable for most users. When the thickness of the adsorption sleeve 31b is 0.8mm, a larger pressure on the skin can be generated during adsorption, so that the skin can be more stably adsorbed, which is suitable for oily skin users.

[0285] Optionally, the chamfer can also be adjusted according to the thickness of the adsorption sleeve 31b. The chamfer is preferably a single-side chamfer structure, which can adopt a circular arc chamfer structure, and the chamfer is as large as possible within the thickness limit, and only a part of the plane needs to be reserved. For example, when the thickness of the adsorption sleeve 31b is 0.8 mm, the size of the chamfer is 0.3 mm, when the thickness of the adsorption sleeve 31b is 1.4 mm, the size of the chamfer is 0.5 mm, and when the thickness of the adsorption sleeve 31b is 2.8 mm, the size of the chamfer is 0.8 mm.

[0286] The above values are not specifically combined here. After the adsorption sleeve 31b adopts the above thickness range and chamfer range, a contact surface with an arc can be formed, so that marks are not easily left during adsorption, and the skin feel is optimized and improved.

[0287] Referring to FIGS. 24 and 25, in an embodiment, the sealing ring 7 is located between the core 31a and the adsorption sleeve 31b in this embodiment, and the sealing ring 7 is connected with the core 31a and the adsorption sleeve 31b respectively, for sealing the gap between the core 31a and the adsorption sleeve 31b to form a good sealing negative pressure cavity 2. In addition, the sealing ring 7 has an elastic deformation part 73, which provides elastic buffering for the core 31a and the adsorption sleeve 31b.

[0288] In the above scheme, the sealing ring 7 can seal the gap between the core 31a and the adsorption sleeve 31b of the beauty head 31. At the same time, by providing the elastic deformation part 73 on the sealing ring 7, the elastic deformation part 73 can give the sealing ring 7 the freedom of elastic stretching and contraction. At this time, when the beauty head 31 is in a vibrating use condition, the adsorption sleeve 31b and the core 31a can always maintain good sealing effect, and the adsorption sleeve 31b is not easy to leak air during vibration. In addition, the impact force of the adsorption sleeve 31b on the skin during vibration can be reduced, providing a better experience.

[0289] At the same time, it can be understood that when the adsorption sleeve 31b is sleeved to the core 31a, the condition that the core 31a is located in the adsorption sleeve 31b includes three position states. The first position state is that the core 31a does not exceed the opening of the adsorption sleeve 31b; the second position state is that the end face of the core 31a is flush with the opening; and the third position state is that the core 31a slightly exceeds the opening of the core 31a. In the above three position relationships, the adsorption sleeve 31b can more stably adsorb the skin. If the core 31a exceeds the opening of the adsorption sleeve 31b too much, because the softness of the skin is limited, it cannot be well covered on the adsorption sleeve 31b, thereby causing the phenomenon of unstable adsorption. Therefore, in order to ensure good adsorption force, the core 31a and the adsorption sleeve 31b adopt the above three setting states.

[0290] In some embodiments, the first position state is adopted in the present embodiment, and the distance between the microneedle wafer 3122 and the opening of the suction sleeve 31b is controlled at 0.5-1.5 mm, and can be 0.5 mm, 1 mm or 1.5 mm. The distance between the microneedle wafer 3122 and the opening of the suction sleeve 31b should be set according to the stimulation degree of the user. It can be known that the greater the distance between the two openings, the greater the movement stroke of the microneedle. The longer the stroke is, the greater the compression degree of the elastic member 314 is, and the greater the force acting on the skin is. Therefore, on the one hand, different pain can be produced, and on the other hand, redness and swelling of sensitive skin may occur.

[0291] Based on this, when the distance between the microneedle wafer 3122 and the opening of the suction sleeve 31b is set at 0.5 mm, the stimulation degree can be reduced to meet the use requirements of users with low pain tolerance and sensitive skin. In addition, when the distance between the microneedle wafer 3122 and the opening of the suction sleeve 31b is set at 1 mm, the stimulation degree is moderate, which is suitable for most users. In addition, when the distance between the microneedle wafer 3122 and the opening of the suction sleeve 31b is set at 1.5 mm, it can be used for piercing users with thick stratum corneum to achieve deep penetration of essence and optimize the cosmetic effect.

[0292] Under the above distance setting, the distance is adjusted according to different requirements, so that the skin can just contact the microneedle wafer 3122 after negative pressure suction. Combined with the vibration effect of the vibration mechanism 9, the pain and discomfort caused by excessive piercing force can be reduced when the skin is pierced. The massage degree is moderate, the skin feeling is optimized, and the specific distance value in actual setting is not limited here.

[0293] Specifically, in one embodiment, the elastic deformation part 73 can be formed of a soft elastic material, such as silicone or rubber structure. At this time, the elastic deformation part 73 has elastic stretching effect and can provide sealing and elastic buffering function to meet the use conditions.

[0294] Referring to FIG. 26, in another embodiment, the sealing ring 7 can also be arranged at other positions, such as the sealing ring 7 can cooperate with the vibration mechanism 9, the cosmetic assembly 3 and other parts, so as to obtain another sealing structure:

[0295] In some embodiments, the cosmetic device comprises a cosmetic device body 1, a vibration mechanism 9, a cosmetic component 3, and a sealing ring 7. The cosmetic device body 1 is provided with a negative pressure sleeve 1a at one end, and the negative pressure sleeve 1a has an opening. The negative pressure sleeve 1a is equivalent to the suction sleeve 31b described above. The vibration mechanism 9 is arranged on the cosmetic device body 1, the cosmetic component 3 is connected to the vibration mechanism 9, the vibration mechanism 9 can drive the cosmetic component 3 to reciprocate, the vibration mechanism 9 is used to drive the cosmetic component 3 to reciprocate, the negative pressure sleeve 1a is sleeved outside the cosmetic device, and the cosmetic component 3 is located in the negative pressure sleeve 1a.

[0296] It can be understood that the arrangement of the cosmetic component 3 inside the negative pressure sleeve 1a includes three positional relationships between the cosmetic component 3 and the negative pressure sleeve 1a. In the first position, the end of the cosmetic component 3 does not exceed the opening of the negative pressure sleeve 1a. In the second position, the end face of the cosmetic component 3 is flush with the opening. In the third position, the cosmetic component 3 slightly exceeds the opening of the cosmetic component 3. In the above three positional relationships, the negative pressure sleeve 1a can more stably suction the skin.

[0297] Further, the sealing ring 7 is made of a material such as silicone or rubber that has elasticity. The sealing ring 7 comprises a first connecting portion 71, an elastic deformation portion 73, and a second connecting portion 72 connected in sequence along the vibration direction. Preferably, the first connecting portion 71, the elastic deformation portion 73, and the second connecting portion 72 are integrally connected, which can ensure good sealing performance of the sealing ring 7.

[0298] It can be understood that in this scheme, the elastic deformation portion 73 comprises a corrugated segment 731 bent towards the inside and / or the outside. Optionally, in this scheme, the elastic deformation portion 73 can also be provided with a reinforcing segment 732. The specific structure of the corrugated segment 731 and the reinforcing segment 732 is not described here.

[0299] The first connecting portion 71 is connected to the cosmetic component 3, and the second connecting portion 72 is connected to the cosmetic device body 1 and / or the negative pressure sleeve 1a. At this time, the sealing ring 7 provides sealing for the negative pressure sleeve 1a and the cosmetic component 3, so as to form a negative pressure cavity 2 between the negative pressure sleeve 1a and the cosmetic component 3.

[0300] In the above technical scheme, the elastic deformation portion 73 on the sealing ring 7 can adapt to the elastic deformation of the sealing ring 7, thereby meeting the sealing function in the vibration environment and solving the problem of insufficient sealing in the vibration condition.

[0301] [Setting of air blowing structure]

[0302] Referring to FIG. 27, in order to promote the absorption of the essence, while adopting the above technical solutions, a blowing structure can be arranged inside the beauty instrument, and by applying the airflow to the skin, on the one hand, the discomfort caused by the needle, light and heating process in the beauty process can be relieved, and on the other hand, a certain massage and the function of promoting the essence to flow into the pores can be played, so that the beauty experience is optimized.

[0303] It can be understood that the beauty instrument in the embodiment can also include a gas supply unit 14 and an airflow channel 15, which are arranged on the beauty instrument body 1, and an air outlet 16 can be arranged on the beauty assembly 3 or the beauty instrument body 1. The airflow channel 15 can adopt a pipeline structure such as a hose, and the gas supply unit 14 can adopt a gas supply pump 142, wherein the two ends of the airflow channel 15 are respectively connected with the air outlet section of the gas supply pump 142 and the air outlet 16. The gas supply pump 142 can generate airflow, and the gas supply unit 14 can send the airflow acting on the skin outward through the airflow channel 15 and the air outlet 16, so as to achieve the effect of improving the beauty experience.

[0304] Further, the airflow channel 15 includes a straight first gas supply branch 154, one end of which is connected with the gas supply pump 142, and the other end is in communication with the air outlet 16. At this time, the straight first gas supply branch 154 can reduce the energy loss as much as possible when the gas collides, so as to ensure a larger wind power size and meet the use experience.

[0305] A beauty instrument and a beauty kit for applying essence under negative pressure are provided to solve the problem of poor control of the essence application area in the prior art.

[0306] Among them, the embodiments of the beauty instrument body 1, the beauty head 31, the negative pressure cavity 2, the negative pressure channel 4, the negative pressure mechanism 5 and the liquid storage cavity 6 can be combined in any way without violating the law of nature according to different needs.

[0307] For example, in some embodiments, the liquid storage cavity 6 has three implementation modes of being arranged in the beauty instrument body 1, being arranged in the main body 32 and being arranged in the container 61. The three implementation modes of the liquid storage cavity 6 can be combined with any one of the plurality of implementation modes of the negative pressure channel 4 to realize the negative pressure adsorption of the liquid.

[0308] Similarly, any one of the implementation modes of the other modules can also be combined in any way without violating the law of nature, and no matter what combination way is adopted, it should be included in the protection scope of the present application.

[0309] Specifically, first, the negative pressure channel 4 adopts the implementation integrated in the main body piece 32; second, the negative pressure mechanism 5 adopts the implementation including the negative pressure pump 51, the electromagnetic valve 52 and the air pressure sensor 53; third, the beauty instrument body 1 adopts the implementation with the first avoiding port 101 and the sliding cover 13; and the beauty head 31 adopts the implementation connected with the main body piece 32 and having the adsorption sleeve 31b, the core body 31a, the adsorption element 3123, the elastic piece 314, the application unit 3121 and the microneedle wafer 3122, the adsorption element 3123 is arranged between the core body 31a and the nanocrystal wafer; then, the negative pressure cavity 2 adopts the implementation with the inner cavity part and the outer cavity part 21 and forms the curved air flow path; in addition, the liquid storage cavity 6 adopts the implementation that the container 61 is detachably connected with the main body piece 32; finally, regarding the optimization of the essence application, the implementation that the main body piece 32 is driven by the vibration mechanism 9 is adopted, and the main body piece 32 is arranged as a consumable and is detachably connected with the vibration connecting piece 92.

[0310] Through the selection of the implementation of each module, a beauty kit that can promote the absorption of essence, guarantee the hygiene safety and facilitate the user to use can be realized.

[0311] It can be understood that in the structural arrangement of the embodiments of the present application, various different implementations can also be obtained, as follows:

[0312] One: a beauty instrument, comprising: a core body 31a connected with a vibration mechanism 9, the core body 31a comprising a gas conveying negative suction channel; an adsorption sleeve 31b, the core body 31a is arranged in the adsorption sleeve 31b, and the core body 31a and the adsorption sleeve 31b form a negative pressure cavity 2 in communication with the negative suction channel, the negative pressure cavity 2 is used for communication with a negative pressure mechanism 5 through the negative suction channel; and a sealing ring 7 connected with the core body 31a and the adsorption sleeve 31b respectively, used for plugging the gap between the core body 31a and the adsorption sleeve 31b, the sealing ring 7 has an elastic deformation part 73, the elastic deformation part 73 is used for providing elastic buffer for the core body 31a and the adsorption sleeve 31b.

[0313] In the scheme, the vibration mechanism 9 can drive the core 31a to vibrate, and then massage the skin. At this time, the sealing ring 7 can seal the gap between the core 31a and the suction sleeve 31b of the beauty head 31, so as to form a negative pressure cavity 2. The negative pressure cavity 2 can be communicated with the negative pressure mechanism 5, so as to suck the skin. Under this condition, the skin can be accurately massaged. At the same time, by arranging the elastic deformation part 73 on the sealing ring 7, the elastic deformation part 73 can give the sealing ring 7 the elastic stretching and contracting freedom.

[0367] Among them, with reference to FIG. 29 and FIG. 33, in the single air pump scheme, based on the above components, the air flow channel 15 is divided into three parts for convenience of description, which are respectively a first air flow channel 151, a second air flow channel 152 and a third air flow channel 153.

[0368] At this time, a kind of beauty instrument can be obtained, which comprises a beauty instrument body 1, the beauty instrument body 1 is provided with a beauty head 31 at one end, further comprising an air supply unit 14 and a first air flow channel 151, the air supply unit 14 is arranged in the interior of the beauty instrument body 1, the beauty instrument body 1 is provided with a gas outlet 16 adjacent to the beauty head 31 at one end, the first air flow channel 151 is connected with the air supply unit 14 and the gas outlet 16, and the air supply unit 14 sends the air flow acting on the skin to the outside through the first air flow channel 151 and the gas outlet 16.

[0369] At this time, the air supply unit 14 can generate an air flow, by pressing the air flow into the air flow channel 15, under the guidance of the air flow channel 15, the air flow blows out from the air outlet 16 and acts on the skin, at this time, the essence on the skin can be pressed to accelerate the penetration into the pores, the absorption effect of the essence is significantly improved, and blowing can accelerate the air flow on the skin surface, and relieve the discomfort of the skin.

[0370] Further, the liquid outlet flow channel 1004 and the second air flow channel 152 are further included, the cosmetic head 31 has a liquid outlet 1002, the liquid outlet flow channel 1004 is used to communicate the liquid outlet 1002 with a liquid storage cavity 6, and the specific connection mode adopts the connection mode of the liquid outlet air pump 141 and the air inlet flow channel 1005 in the foregoing, and this part is not repeated; Further, the second air flow channel 152 is used to communicate the air supply unit 14 with the liquid storage cavity 6, in the embodiment, the liquid storage cavity 6 is communicated with the second air flow channel 152 through the air inlet flow channel 1005, the connection mode is not repeated here, and in this scheme, the air supply unit 14 adopts a single air pump, and the air supply unit 14 is connected with the first air flow channel 151 and the second air flow channel 152 respectively.

[0372] It needs to be explained that under the condition of adopting a single air pump, in order to simultaneously connect the air supply unit 14 with the first air flow channel 151 and the second air flow channel 152, a third air flow channel 153 also needs to be set, therefore, in the single air pump scheme, the air supply unit 14 includes a gas supply air pump 142, which can be regarded as replacing the liquid outlet air pump 141 in the foregoing, or only the liquid outlet air pump 141 can also realize the air outlet effect. When connected, one end of the third air flow channel 153 is connected with the output end of the gas supply air pump 142, and the other end is connected with the first air flow channel 151 and the second air flow channel 152 respectively, here, the third air flow channel 153, the first air flow channel 151 and the second air flow channel 152 form a tree-shaped air channel structure, which can realize the gas shunting action.

[0373] It needs to be explained that the third air flow channel 153, the first air flow channel 151 and the second air flow channel 152 can be connected at different points at the same time, or can be connected at the same point at the same time.

[0374] Further, in order to optimize the air flow effect, the cosmetic instrument further comprises a switching valve 143, wherein the switching valve 143 has a multi-channel structure, the third air flow channel 153, the first air flow channel 151 and the second air flow channel 152 are fixedly connected to the switching valve 143 at the same time, and the switching valve 143 can switch the air flow so that the air flow flows from the third air flow channel 153 to the first air flow channel 151 or the second air flow channel 152 alone.

[0375] Under the action, the air flow can be controlled and adjusted, and by separately guiding the air flow to one of the channels, the air flow can have a good flow rate, and the function is more flexible and stable.

[0376] Further, at least one of the first air flow channel 151, the second air flow channel 152 and the third air flow channel 153 is a hose, preferably in the embodiment, all of them are hose structures, wherein the hose structure is convenient for wiring and layout, and can also bypass other components to avoid interference.

[0377] Further, in the specific setting, if the first air flow channel 151, the second air flow channel 152 and the third air flow channel 153 have a bending part, it will cause kinetic energy loss when the gas is discharged, and the force of the discharged gas, at this time, in order to ensure the discharge effect, at least one of the first air flow channel 151, the second air flow channel 152 and the third air flow channel 153 is arranged in a straight shape, under the arrangement of the above structure, the straight structure can reduce the collision loss in the air flow process as much as possible, so that the air flow can maintain a large flow rate. Preferably, in the embodiment, the first air flow channel 151 and the third air flow channel 153 are arranged in a straight shape.

[0378] Through the arrangement of the above structure, the first air flow channel 151 and the third air flow channel 153 form a first air supply branch 154 for providing air flow to the air outlet 16, and the second air flow channel 152 and the third air flow channel 153 form a second air supply branch 155 for providing air flow to the liquid storage cavity 6.

[0379] In actual application, it is found that the air flow intensity demand of the air outlet 16 is large, otherwise the user's feeling of blowing will be weak, based on this, preferably, the first air supply branch 154 maintains a straight shape as a whole, and in the setting, only the first air flow channel 151 and the third air flow channel 153 need to be coaxially arranged, so that the air flow loss in the first air supply branch 154 can be avoided as much as possible.

[0380] However, due to space limitations in the cosmetic instrument body 1, the first air supply branch 154 will inevitably interfere with other components. In order to ensure that the air outlet 16 has good air outlet strength, an avoidance bending portion can be provided on the first air supply branch 154, and the proportion of the avoidance bending portion to the total length of the first air supply branch 154 is not more than 20%. In this way, the airflow loss can be minimized to ensure the blowing effect.

[0381] Correspondingly, if there is a liquid outlet effect in different models of products, the position of the air supply pump 142 can be adjusted to make the second air supply branch 155 straight, and an avoidance bending portion can be provided on the second air supply branch 155. Correspondingly, the proportion of the avoidance bending portion to the total length of the first air supply branch 154 is not more than 20% to ensure sufficient airflow strength when liquid is discharged.

[0382] It can be understood that the setting position of the air outlet 16 is adjusted according to actual needs, such as being provided on the cosmetic instrument body 1 and being provided adjacent to the cosmetic head 31, or being directly provided on the cosmetic head 31 to realize the blowing function while beautifying. In addition, the present scheme can be combined with the vibration mechanism 9 to be provided synchronously, such as connecting the cosmetic head 31 with the vibration mechanism 9, and driving the cosmetic head 31 to reciprocate by the vibration mechanism 9 to realize the massage effect.
