[0122] Please refer to Figures 1 to 3The utility model embodiment provides a beauty instrument for skin care, which mainly comprises a beauty instrument body 1, a negative pressure cavity 2, a beauty head 31, a negative pressure channel 4 and a negative pressure mechanism 5.

[0123] The negative pressure cavity 2 is arranged at one end of the beauty instrument body 1, and the negative pressure cavity 2 is used for being connected to a liquid storage cavity 6 for storing essence liquid.

[0124] Specifically, the beauty instrument body 1 mainly provides assembly positions for various components, and the beauty head 31 is used for contacting the skin and playing a beautifying role.

[0125] In addition, the beauty head 31 comprises a suction element 3123 arranged in the negative pressure cavity 2, and the suction element 3123 has a porous structure for retaining the essence liquid.

[0126] Furthermore, the negative pressure mechanism 5 is arranged in the beauty instrument body 1 in the embodiment, the negative pressure mechanism 5 is connected with the negative pressure channel 4 and is used for sucking air in the negative pressure channel 4.

[0127] In the technical scheme of the utility model, the skin area to which the essence liquid needs to be applied is adsorbed in the negative pressure area by the negative pressure adsorption mode, the application area control of the essence liquid is improved, and unnecessary damage caused by diffusion of the essence liquid is reduced.

[0128] 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.

[0129] [About the negative pressure channel 4]

[0130] In the embodiment, the negative pressure channel 4 includes a first segment and a second segment, the first segment is used to communicate the liquid storage cavity 6 and the negative pressure cavity 2, and the second segment is used to communicate 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 pipe-shaped 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.

[0131] It can be understood that the design of the pipe-shaped passage and the pipe structure can make the channel smoother and the fluid transportation more smooth; the design of the pipe-shaped passage has higher assembly efficiency, and the design of the pipe structure is more convenient for production, manufacturing and assembly.

[0132] In an embodiment, referring to Figure 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 piece 32, the inside of the main body piece 32 is hollow, the inside of the main body piece 32 is provided with a first negative pressure pipe 41 and a second negative pressure pipe 42, the first negative pressure pipe 41 is arranged in the inside of the main body piece 32 and forms the first segment of the negative pressure channel 4, one end of the first negative pressure pipe 41 is connected with the beauty head 31 and communicates with the negative pressure cavity 2, and the other end is connected with the connecting part 33; the second negative pressure pipe 42 is arranged in the inside of the main body piece 32 and forms the second segment of the negative pressure channel 4, one end communicates with the negative pressure cavity 2, and the other end is connected with the negative pressure mechanism 5.

[0133] Specifically, the main body piece 32 is in a shell-shaped structure, the first negative pressure pipe 41 mainly plays a role of liquid output, and the second negative pressure pipe 42 plays a role of negative pressure suction.

[0134] Specifically, referring to Figure 3 and Figure 4 , the first negative pressure pipeline 41 can be installed inside the main body 32 and forms the first section of the negative pressure channel 4. One end of the first negative pressure pipeline 41 is connected with the beauty head 31 and communicates with the negative pressure cavity 2, and the other end is connected with the liquid storage cavity 6. The first negative pressure pipeline 41 guides the essence liquid to flow to the beauty head 31, realizing the liquid output effect.

[0135] It can be understood 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 arranged in the beauty instrument body 1, which can make the structure more compact.

[0136] Further, the second negative pressure pipeline 42 can also be installed inside the main body 32 and forms the second section of the negative pressure channel 4. One end of the second negative pressure pipeline 42 communicates with the negative pressure cavity 2, and the other end is connected with the negative pressure mechanism 5.

[0137] 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. At the same time, 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. The first negative pressure pipeline 41 is responsible for supplying liquid to flow out, and the second negative pressure pipeline 42 is responsible for supplying gas to be adsorbed. The two operate independently and are not easy to interfere with each other. It is convenient for production and assembly, and the structure is compact.

[0138] Specifically, 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. They can also be independent pipe structures 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. In the second negative pressure pipeline 42, a hard pipe structure can be adopted, which can prevent the second negative pressure pipeline 42 from deforming during negative pressure operation and keep the inside unobstructed, better realizing the negative suction function.

[0139] In an embodiment, in combination with Figures 2 to 7 , in order to improve the operation convenience and safety, the main body 32 and the beauty instrument body 1 are arranged in a detachable connection.

Specifically, the first communication part 111 is inserted into the second communication part 112 to realize the connection, and the position of the first communication part 111 inserted into the second communication part 112 is sleeved with the air inlet sealing ring 113.

[0143] Further, refer to Figure 3 In order to control the slow and uniform flow of the essence liquid to the outside, a slow flow design can be added. In an embodiment, a slow flow part 43 can be arranged in the negative pressure channel 4, and the slow flow part 43 has a porous structure. The slow flow part 43 is arranged between the liquid storage cavity 6 and the cosmetic head 31. The materials that can be used include sponge, cotton, porous silica gel or porous ceramic, and other structures that can achieve the slow flow effect can be tried. The loose porous structure can slow down the flow rate of the essence liquid. In this case, the essence liquid can be evenly and slowly transported to the cosmetic head 31, realizing stable liquid output effect.

[0144] The arrangement of the slow flow part 43 also facilitates the later use and maintenance. For example, when the negative pressure channel 4 is blocked, the slow flow part 43 can be replaced to solve the problem. In another embodiment, 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 of any part between the liquid storage cavity 6 and the cosmetic head 31 is arranged to be smaller than the inner diameter of the negative pressure channel 4 of 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, and the hose is arranged in the clamping groove. 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.

[0145] [About the negative pressure mechanism 5]

[0146] Please refer to Figure 2The negative pressure mechanism 5 comprises a negative pressure pump 51 connected with the negative pressure channel 4 for extracting air from the negative pressure channel 4, and an electromagnetic valve 52 connected with the negative pressure channel 4 for supplementing gas to the negative pressure channel 4.

[0147] In some embodiments, the negative pressure mechanism 5 comprises a negative pressure pump 51 fixedly installed inside the cosmetic instrument body 1, and a suction end of the negative pressure pump 51 connected with the second section of the negative pressure channel 4 for extracting air from the negative pressure channel 4.

[0148] In some embodiments, the negative pressure mechanism 5 further comprises an electromagnetic valve 52 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 cosmetic instrument from the skin without causing harm to the skin.

[0149] Further, to realize automatic control of the negative pressure pump 51 and the electromagnetic valve 52, a gas pressure sensor 53 and a control element are further included, the gas pressure sensor 53 is in communication with the negative pressure channel 4, the control element is connected with the gas pressure sensor 53, the negative pressure pump 51 and the electromagnetic valve 52, the gas pressure sensor 53 is used to detect the air pressure in the negative pressure channel 4 to form a negative pressure signal and send the negative pressure signal to the control element; the control element forms a control signal based on the negative pressure signal and sends the control signal to the negative pressure pump 51 and the electromagnetic valve 52 to control the start and stop of the negative pressure pump 51 and the electromagnetic valve 52.

[0150] Specifically, the cosmetic instrument further comprises a main control circuit board 17, the main control circuit board 17 is provided with a control element, and the negative pressure mechanism 5 further comprises a gas pressure sensor 53 arranged on the main control circuit board 17, wherein a receiving end of the gas pressure sensor 53 is in communication with the negative pressure channel 4, the gas pressure sensor 53 can detect the negative pressure condition in the negative pressure channel 4, and further can obtain the negative pressure condition of the negative pressure cavity 2 and synchronously generate a negative pressure signal. In addition, the control element is connected with the gas pressure sensor 53, the negative pressure pump 51 and the electromagnetic valve 52, the control element can adopt a control chip, and any element that can realize control function can be used, which is not specifically limited here.

[0151] Based on this, after the gas 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, the control element analyzes based on the negative pressure signal and forms a control signal, and then the control element sends the control signal to the negative pressure pump 51 and the electromagnetic valve 52 to control the start and stop of the negative pressure pump 51 and the electromagnetic valve 52, realizing automatic control and optimizing the use experience.

[0152] Further, 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, and the air pressure sensor 53, the negative pressure pump 51, the electromagnetic valve 52 and the negative pressure channel 4 are connected to the interfaces of the multi-way valve 54. The number of interfaces is related to the number of elements required to be communicated by the negative pressure channel 4, and in the embodiment, four interfaces are selected, i.e. a four-way valve structure. The number of interfaces is not specifically limited, and 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 through the interfaces, so that the internal pipeline is more compact.

[0153] [About the liquid storage cavity 6]

[0154] In the embodiment, the liquid storage cavity 6 can be formed in the cosmetic body; or, when the cosmetic device comprises the main body 32, the liquid storage cavity 6 is formed in the main body 32; or, the liquid storage cavity 6 can be the accommodation space of a container 61. The specific embodiments are described below.

[0155] Please refer to Figure 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 62 is arranged in the main body 32, and a separate space is separated by the partition 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 the above arrangement, the basic function of ensuring the delivery of the essence liquid is realized, and different essence liquids can be injected according to the needs of the user, so as to meet the different needs of the user.

[0156] 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.

[0157] Through the above 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.

[0158] 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 the above arrangement, the design of the cosmetic body 1 can be simplified, and the convenience of the user in supplementing the essence liquid can be improved.

[0159] 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 the consumable, 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.

[0160] 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.

[0161] 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.

[0162] 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 the beauty instrument 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, and 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 demand of supplementing the essence liquid, and can be provided with the transparent window according to the demand of observing the remaining amount of the essence liquid, and other specific settings will not be described here.

[0163] In some embodiments, the main body 32 and the container 61 are further included, the main body 32 is arranged on the beauty instrument body 1, the beauty head 31 is arranged on the main body 32, the main body 32 is provided with the connecting part 33, the container 61 is formed with the liquid storage cavity 6, the main body 32 is detachably connected with the container 61 through the connecting part 33, and the negative pressure channel 4 is communicated with the container 61 through the connecting part 33.

[0164] Please refer to Figure 9 In the manner in which the containing space of the container 61 is arranged 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 the essence liquid, and 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, and the convenience of observing the remaining amount of the essence liquid is further optimized.

[0165] In this embodiment, referring to Figure 10 The cosmetic device and the container 61 constitute a cosmetic kit. When the container 61 is assembled to the cosmetic device body 1, the container 61 is simultaneously communicated with the negative pressure mechanism 5 through the negative pressure channel 4, thereby realizing the supply and delivery of the essence liquid. The negative pressure channel 4 and the negative pressure mechanism 5 are arranged as described above, and will not be described here again.

[0166] In this embodiment, referring to Figure 9 and Figure 10 To realize the assembly of the cosmetic kit, the cosmetic device is provided with a connecting part 33. After the container 61 is assembled to the cosmetic device through the connecting part 33, the cosmetic device can be communicated with the container 61, and then the essence liquid can be taken out from the container 61 and delivered to the human skin, thereby realizing the skin care.

[0167] Please refer to Figure 10 Specifically, the cosmetic device 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 part 330. The connecting part 33 comprises the aforementioned bottle mouth slot 339 and the plug-in part 330.

[0168] At this time, after the container 61 is inserted into the bottle mouth slot 339, on the one hand, the bottle mouth slot 339 can clasp the container 61 to limit the container 61 from separating from the cosmetic device; on the other hand, the connecting part 33 will be inserted into the container 61 to take the essence liquid from the container 61.

[0169] Specifically, to achieve the above-mentioned purpose, when a new container 61 is needed, the head of the container 61 is inserted downward into the bottle mouth slot 339. 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 part 32. When the head of the container 61 is inserted downward into the bottle mouth slot 339, simultaneously, the connecting part 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.

[0170] During the assembly and disassembly 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 of poor convenience of the existing cosmetic kit assembly and disassembly operation by screwing operation.

[0171] In some embodiments, referring to Figure 5 and Figure 9In order to smoothly deliver the essence liquid in the container 61 to the beauty head 31, the connecting portion 33 is provided with a flow outlet 331 and an air inlet 332, the negative pressure channel 4 is connected with the connecting portion 33 and communicates with the beauty head 31, and the air inlet 332 communicates with the container 61 and the outside.

[0172] Specifically, the connecting portion 330 is provided with the flow outlet 331 and the air inlet 332, one end of the first section of the negative pressure channel 4 is fixedly connected with the connecting portion 330 and communicates with the flow outlet 331, and the air inlet 332 is exposed to the outside to realize the communication between the container 61 and the outside. It can be understood that, due to the tension of the essence liquid itself, the essence liquid itself is not easy to flow out from the air inlet 332 when the connecting portion 330 is connected with the container 61.

[0173] Through the above arrangement, the flow outlet 331 and the air inlet 332 are integrated on the connecting portion 330, so that when the connecting portion 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. At the same time that the negative pressure is formed in the negative pressure channel 4, the atmospheric pressure balance between the inside and the outside of the container 61 is maintained through the air inlet 332, so that the liquid delivery is more smooth.

[0174] Further, please refer to Figure 5 and Figure 10 In this embodiment, the groove wall of the bottle mouth slot 339 is provided with a plurality of outwardly protruding groove wall bosses 338; the groove 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 groove wall boss 338 of the beauty instrument.

[0175] The groove wall of the bottle mouth slot 339 in this embodiment is provided with outwardly protruding groove wall bosses 338, which can effectively clamp the edge of the container 61 to 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 tightly cooperates with the groove wall boss 338 to ensure 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 liquid supply are improved.

[0176] Optionally, as Figure 10As shown, the container 61 further comprises a sealing plug 614 for sealing the bottle mouth 612, and an aluminum film 615 for covering the sealing plug 614 and the bottle mouth 612. The sealing plug 614 is provided with a plug hole 6141 for inserting the insertion part 330, and a frangible film 6142 for covering the plug hole 6141. The aluminum film 615 is provided with a film avoiding hole for the connecting part 33 to pass through, corresponding to the position of the plug hole 6141.

[0177] When the insertion 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, and to ensure safety and hygiene. Meanwhile, the frangible film 6142 can prevent the essence liquid in the container 61 from flowing out, so as to facilitate storage and transportation. When the container 61 is inserted into the bottle mouth slot 339, the insertion part 330 is inserted into the plug hole 6141, and the frangible film 6142 is pierced by the insertion part 330, so as to realize the outflow of the essence liquid. This design can ensure the sealing of the container 61, and is convenient to use. The aluminum film 615 is mainly used for limiting the sealing plug 614 and the bottle mouth 612, so as to avoid the sealing plug 614 from being pushed out of the bottle mouth 612 under the action of air pressure when the pressure in the container 61 is high.

[0178] Further, in this embodiment, the insertion part 330 is provided in a columnar or conical shape. The opening of the container 61 or the insertion part 330 can be provided with an elastic structure, such as flexible rubber, so that the insertion part 330 is in interference fit with the container 61, so as to avoid the essence liquid from leaking from the joint between the insertion part 330 and the container 61.

[0179] Optionally, referring to Figure 10 and Figure 11 , the insertion part 330 comprises a top surface in a conical surface structure 334, and a circumferential side surface in a cylindrical surface structure 335. The circumferential side surface of the cylindrical surface structure 335 is used for interference fit with the hole wall of the plug hole 6141 of the container 61, so as to seal the gap between the insertion part 330 and the container 61.

[0180] 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 is in interference fit with the inner wall of the plug hole 6141, so as to ensure the sealing and stability of the essence liquid in the transmission process. The top surface of the conical surface structure 334 is beneficial to easily pierce the frangible film 6142, and saves the effort required for piercing 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 insertion part 330, so as to improve the sealing performance between the insertion part 330 and the sealing plug 614.

[0181] It can be understood that the insertion angle of the vial can be set to multiple, at this time, taking the plane where the liquid outlet 1002 is located as the reference, the length direction of the beauty instrument is also perpendicular to the plane, at this time, the extension direction of the insertion part 330 and the angle formed by the plane where the liquid outlet 1002 is located is between 0 degrees and 90 degrees, at this time, the insertion 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, at this angle, the insertion assembly of the vial can be realized, according to actual needs, by adjusting the shape of the beauty instrument body 1 and adjusting the structure angle of the insertion part 330, the above insertion effect can be met, which is not limited specifically here, in this embodiment, the angle is selected as 0 degrees as an example.

[0182] In summary, the related settings of the connecting part 33 and the container 61 have the following advantages:

[0183] ①In the beauty instrument, a bottle opening slot 339 is arranged for the insertion of the container 61, and subsequent assembly and disassembly of the container 61 does not require complicated twisting operation, but only simple plugging and unplugging operation, which is convenient to operate;

[0184] ②The taper structure 334 and the cylindrical surface structure 335 of the connecting part 33 are designed to ensure interference fit with the plug hole 6141 of the container 61, achieve good sealing during the transmission of the essence liquid, and avoid leakage problems;

[0185] ③The design of the sealing plug 614 and the fragile film 6142 of the container 61 ensures that the container 61 remains sealed during storage and transportation, ensuring the quality and activity of the essence liquid.

[0186] It can be understood that there are many structures of the connecting part 33 that can realize insertion and communication, and another connecting part 33 is provided in the embodiment, which is suitable for the beauty instrument and the beauty kit in the foregoing embodiments, and can also realize the functions of air supply and liquid delivery.

[0187] On the basis of the setting of the foregoing communication part 11, the unexplained features are explained by the foregoing embodiments, which will not be described here again. Referring to Figure 12 The difference between the structure of the connecting part 33 and the foregoing embodiments is that:

[0188] The connecting part 33 includes an air inlet needle tube 336 for supplying air to the container 61, and an outlet needle tube 337 for supplying liquid outward from the container 61.

[0189] Correspondingly, the sealing plug 614 is provided with an air inlet needle hole 6143 for the insertion of the air inlet needle tube 336, an air inlet film covering the air inlet needle hole 6143, an outlet needle hole 6144 for the insertion of the outlet needle tube 337, and an outlet film covering the outlet needle hole 6144.

[0190] 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, the liquid outlet needle tube 337 and the liquid outlet film are aligned; then press the container 61 downward, so that the air inlet needle tube 336 pierces the air inlet film and is inserted into the container 61 through the air inlet needle hole 6143, and the liquid outlet needle tube 337 pierces the liquid outlet film and is inserted into the container 61 through the liquid inlet and 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.

[0191] The connection part 33 provided by the above application method 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. How to take the essence liquid from the container 61 by pressure difference will not be described here.

[0192] From the above setting of the beauty instrument, it can be understood that in the way of setting the containing space of the container 61 as the liquid storage cavity 6, there are two cases of the setting object of the connection part 33 due to the setting of the beauty instrument: one is that when the beauty instrument is not provided with the main body 32, the connection part 33 is arranged on the beauty instrument body 1, and the container 61 is directly assembled and connected with the beauty instrument body 1 through the connection part 33; the other is that when the beauty instrument is provided with the main body 32, the connection part 33 is arranged on the main body 32, and the container 61 is directly assembled and connected with the main body 32 through the connection part 33. The two setting modes of the connection part 33 will be described below.

[0193] In the case that the connection part 33 is arranged on the beauty instrument body 1, the beauty instrument body 1 is detachably connected with the container 61 through the connection part 33, and the container 61 is in communication 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, which will not be described here.

[0194] In the case that the connection part 33 is arranged on the main body 32, as shown in Figure 10 , the connection part 33 is the same as the above connection part 33 in structure except for the different setting position, which will not be described here. In the setting mode of the embodiment, the connection part 33 is arranged on the main body 32, not on the beauty instrument body 1 as described above. Specifically, the connection part 33 is connected with or integrally formed on the main body 32. Moreover, the main body 32 is also provided with the above negative pressure channel 4. When the container 61 is connected with the main body 32 through the connection part 33, the container 61 is in communication with the negative pressure channel 4, realizing the liquid outlet function.

[0195] Further, referring to Figure 13The main body 32 is provided with a positioning recess 333, which is the bottle mouth slot 339 described above. The positioning recess 333 has a bottom wall and a side wall connected to the bottom wall, and the insertion part 330 is arranged on the bottom wall. The side wall is provided with a limiting part, which is the slot wall boss 338 described above. Of course, the slot wall boss 338 described above can also be replaced by other limiting modes described below. In some embodiments, the limiting part can be arranged as a surface of the side wall, and the extension profile of the entire side wall is matched with 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 to the insertion part, thereby achieving the effect of positioning the assembly of the container 61, so that the container 61 can be more quickly and accurately connected to the insertion part 33, and the use experience is further optimized and improved.

[0196] It should be noted that the limiting part can also be a sliding limiting structure such as a sliding block and a sliding rail, and any structure that can guide the insertion and assembly of the container 61 and the insertion part 33 can be used, which is not limited here.

[0197] It can be understood that in the embodiment in which the insertion part 33 is arranged on the main body 32, when the main body 32 is arranged inside the beauty instrument body 1, referring to Figure 13 Here, when the main body 32 is arranged inside the beauty instrument body 1, a first avoiding opening 101 is arranged on one side of the beauty instrument body 1, which penetrates the inside and outside of the beauty instrument body 1. The first avoiding opening 101 is arranged at a position corresponding to the insertion part 33 on the main body 32, and the first avoiding opening 101 can expose the insertion part 33 for disassembly of the container 61.

[0198] By installing the container 61 into the insertion part 33 from the outside to the inside, part of the container 61 can be left outside the beauty instrument body 1, which is convenient for users to disassemble the container 61. When the container 61 is made of transparent material, it is also convenient for users to observe the remaining amount of essence liquid, so that customers can selectively replace the container 61 regularly, reduce the problem of bacterial growth caused by long-term residual of essence liquid, and make the skin care environment cleaner and more sanitary.

[0199] [About the beauty instrument body 1]

[0200] In this embodiment, the liquid storage cavity 6 has a plurality of different arrangement modes, and the beauty instrument body 1 is correspondingly provided with a structure for adding or replacing the essence liquid container 61 corresponding to each arrangement mode of the liquid storage cavity 6.

[0201] Specifically, in the arrangement mode in which the liquid storage cavity 6 is arranged in the beauty instrument body 1, an opening for supplementing the addition of essence liquid is correspondingly arranged on the beauty instrument body 1. In the arrangement mode in which the container 61 is arranged outside the beauty instrument body 1, a first avoiding opening 101 for disassembling the container 61 is correspondingly arranged on the beauty instrument body 1.

[0202] Because of the above arrangement, foreign matter such as dust from the outside is easy to enter the liquid storage cavity 6 from the opening or the first escape port 101, polluting the subsequent added essence liquid. In order to improve the sanitary safety of the beauty care environment, the beauty instrument further comprises a sliding cover 13 for shielding the above-mentioned opening or the first escape port 101. The following will be described in detail by taking the sliding cover 13 shielding the first escape port 101 as an example, and the arrangement of the sliding cover 13 shielding the opening is the same as described below, and will not be repeated.

[0203] Reference Figure 15 , the surface of the beauty instrument body 1 is further provided with a first escape port 101 for exposing the connecting part 33, and the beauty instrument further comprises a sliding cover 13 which is in sliding connection with the beauty instrument body 1. Among them, the sliding cover 13 has a closing state of sliding to cover relative to the beauty instrument body 1, and has an opening state of sliding to open the first escape port 101 relative to the beauty instrument body 1.

[0204] When the container 61 needs to be loaded, the sliding cover 13 is slid to the opening state, so that the first escape port 101 is exposed, and then the container 61 can be inserted into the first escape port 101; after the container 61 is taken out, the sliding cover 13 is slid to the closing state, so that the first escape port 101 is covered, that is, the foreign matter such as dust is prevented from entering the first escape port 101. The arrangement of the sliding cover 13 can effectively solve the problem that foreign matter such as dust from the outside is easy to enter the beauty instrument through the mounting position of the container 61, and guarantee the sanitary safety of the beauty care environment.

[0205] Specifically, referring to Figures 15 to 19 , the beauty instrument body 1 is provided with a guide groove 103 extending along the sliding direction of the sliding cover 13; the surface of the sliding cover 13 close to the beauty instrument body 1 is provided with a guide protrusion 131; wherein the guide protrusion 131 is inserted into the guide groove 103 and slides along the guide groove 103 after being driven.

[0206] The cooperation of the guide groove 103 and the guide protrusion 131 realizes the precise sliding connection of the sliding cover 13 and the beauty instrument body 1. When the sliding cover 13 slides along the guide groove 103, the guide protrusion 131 is inserted into the guide groove 103, which guarantees the stability of the sliding cover 13 during the sliding process, avoiding skewing or jumping.

[0207] Referring to Figure 16 and Figure 17 , the beauty instrument body 1 is provided with a positioning groove 104 extending along the sliding direction of the sliding cover 13. The surface of the sliding cover 13 close to the beauty instrument body 1 is provided with a positioning protrusion 132; wherein the positioning protrusion 132 is inserted into the positioning groove 104 and slides along the positioning groove 104.

[0208] The slot wall of the positioning slot 104 is provided with a switch positioning block 105 that slides against the positioning protrusion 132: when the sliding cover 13 is in the closed state, the switch positioning block 105 is located on the side of the positioning protrusion 132 away from the first avoiding port 101, which can prevent the sliding cover 13 from sliding away from the first avoiding port 101, thereby maintaining the closed state of the sliding cover 13; when the sliding cover 13 is in the open state, the switch positioning block 105 is located on the side of the positioning protrusion 132 close to the first avoiding port 101, which can prevent the sliding cover 13 from sliding close to the first avoiding port 101, thereby maintaining the open state of the sliding cover 13.

[0209] Continuing to refer to Figure 18 and Figure 19 , the switch positioning block 105 is mainly used to maintain the stability of the open state and the closed state. When it is necessary to switch the state of the sliding cover 13, a certain pushing force needs to be applied to push the sliding cover 13 to overcome the resistance between the switch positioning block 105 and the positioning protrusion 132, so that the sliding cover 13 slides over the switch positioning block 105.

[0210] Optionally, the number of the positioning slot 104 and the positioning protrusion 132 is two, and the two positioning slots 104 are symmetrically arranged about the guide slot 103. The arrangement of the two positioning slots 104 about the guide slot 103 further improves the connection stability of the sliding cover 13 and the beauty instrument body 1. The design of the two positioning slots 104 makes the sliding cover 13 more stable during sliding, further avoiding the skewing or jumping of the sliding cover 13 during sliding.

[0211] In this embodiment, the positioning slot 104 is a through slot. The positioning protrusion 132 is connected with a hooking part 133 located in the beauty instrument body 1; the width dimension of the hooking part 133 is greater than the slot width dimension of the positioning slot 104, so as to limit the hooking part 133 from disengaging from the beauty instrument body 1 through the positioning slot 104.

[0212] Further, the beauty instrument body 1 is provided with a disassembly slot 107 that communicates to one end of the positioning slot 104 close to the first avoiding port 101; the width dimension of the disassembly slot 107 is greater than the width dimension of the hooking part 133, so that the hooking part 133 enters and exits the beauty instrument body 1 through the disassembly slot 107.

[0213] The width dimension of the hooking part 133 is greater than the slot width dimension of the positioning slot 104, so that the hooking part 133 will not easily fall off when sliding in the positioning slot 104, thereby improving the connection stability of the sliding cover 13 and the beauty instrument body 1.

[0214] When the sliding cover 13 needs to be detached, the hooking part 133 needs to be slid to below the dismounting slot 107 first, and then the sliding cover 13 is lifted upward, in the process of the upward movement of the sliding cover 13, the hooking part 133 passes through the dismounting slot 107, thereby the beauty instrument body 1 can be detached. Similarly, when the sliding cover 13 needs to be mounted, the hooking part 133 also needs to pass through the dismounting slot 107 first, and then the sliding cover 13 is pushed horizontally, so that the positioning protrusion 132 enters the positioning slot 104.

[0215] Optionally, referring to Figure 19 , the slot wall of the positioning slot 104 is further provided with a dismounting positioning block 106; when the surface of the positioning protrusion 132 towards the first avoiding opening 101 abuts against the dismounting positioning block 106, the positioning protrusion 132 is partially or entirely located in the positioning slot 104.

[0216] It can be understood that generally, when the user performs the push cover operation of opening and closing the cover, the positioning protrusion 132 slides on the side of the dismounting positioning block 106 away from the first avoiding opening 101, that is, the positioning protrusion 132 is always at least partially located in the positioning slot 104, so that the user can avoid accidentally lifting the sliding cover 13 upward, causing the sliding cover 13 to be detached from the beauty instrument body 1. That is, when the user pushes the sliding cover 13 towards the first avoiding opening 101, the sliding cover 13 will first abut against the dismounting positioning block 106, at this time, the user can feel obvious resistance, thereby knowing that the limit position of the closed cover state has been reached, and the sliding cover 13 does not need to be continuously pushed.

[0217] If the user not only wants to close the cover, but also wants to detach the sliding cover 13, the sliding cover 13 can be continuously pushed at this time, so that the positioning protrusion 132 passes through the dismounting positioning block 106, at this time, the positioning protrusion 132 completely leaves the positioning slot 104 with a smaller width size, and completely enters the dismounting slot 107 with a larger width size, and the sliding cover 13 can be detached by lifting upward. That is, the dismounting positioning block 106 can play a certain foolproof role, effectively avoiding that the user accidentally detaches the sliding cover 13 when closing the cover.

[0218] Optionally, the opening and closing positioning block 105 and the dismounting positioning block 106 are located on the same slot wall of the positioning slot 104, and the dismounting positioning block 106 is located on the side of the positioning protrusion 132 close to the first avoiding opening 101. The positioning protrusion 132 is provided with an abutting boss 1321 for sliding abutment with the opening and closing positioning block 105 and the dismounting positioning block 106. The side of the opening and closing positioning block 105 and / or the dismounting positioning block 106 away from the abutting boss 1321 is provided with a resilient slot 108. It can be understood that the opening and closing positioning block 105 and the dismounting positioning block 106 can of course be located on different slot walls of the positioning slot 104, and the resilient slot 108 is arranged adjacent to the dismounting positioning block 106.

[0219] The abutment boss 1321 protrudes towards the switch positioning block 105 and the disassembly positioning block 106. When the user pushes the sliding cover 13 so that the abutment boss 1321 protrudes over the switch positioning block 105 or the disassembly positioning block 106, the switch positioning block 105 and the disassembly positioning block 106 are abutted by the abutment boss 1321 and are displaced and deformed towards the corresponding elastic groove 108, thereby providing the user with a damping feeling of clamping and a "click" sound, and the user can determine whether the positioning boss 132 has successfully passed over the switch positioning block 105 or the disassembly positioning block 106 through the clamping feeling and the sound.

[0220] In summary, the beauty instrument and the beauty kit provided by the embodiment have the following advantages:

[0221] ①By designing the sliding connection between the sliding cover 13 and the beauty instrument body 1, the installation position of the container 61 (i.e., the first avoiding opening 101 and the connecting part 33) can be completely covered after the container 61 is pulled out, effectively preventing dust and other foreign matters from entering the interior of the beauty instrument, and keeping the beauty instrument clean and sanitary;

[0222] ②The design of the switch positioning block 105 makes the sliding cover 13 stable in the open cover state and the closed cover state, and prevents accidental sliding due to external force, thereby ensuring normal use of the beauty instrument;

[0223] ③The design of the hooking part 133, the disassembly groove 107, and the disassembly positioning block 106 not only provides the disassembly function of the sliding cover 13, but also has a certain foolproof function, thereby avoiding accidental disassembly of the sliding cover 13 when the cover is closed, and improving the use reliability;

[0224] ④The design of the elastic groove 108 and the abutment boss 1321 provides obvious clamping feeling and sound feedback, so that the user can clearly perceive the state change of the sliding cover 13, and the user experience is improved.

[0225] In the embodiment, the main part 32 is detachably installed in the beauty instrument body 1, and the container 61 is detachably connected to the main part 32, so that the problem that the delivery part of the essence cannot be cleaned or replaced can be solved. The disassembly structure of the main part 32 and the container 61 will be described in detail.

[0226] In one embodiment, please refer to Figure 2 、 Figure 3 、 Figure 10 and Figure 18The mounting port 102 is located at an end surface of the beauty instrument body 1, and the first avoiding port 101 is located at a circumferential surface of the beauty instrument body 1. The mounting port 102 and the first avoiding port 101 are in communication with each other through an internal space of the beauty instrument body 1. The main body member 32 is in plug-in connection with the beauty instrument body 1 through the mounting port 102, and the container 1 is in plug-in connection with the main body member 3 through the first avoiding port 201, so as to connect the liquid outlet flow channel 1004 (i.e., the first negative pressure pipeline 41) in the main body member 3.

[0227] Please continue to refer to Figure 2 and Figure 10 The beauty instrument and the beauty kit provided by the embodiment are as follows: the beauty head 31 is connected to one end of the main body member 32 and exposed outside the beauty instrument body 1. When it is necessary to disassemble and clean the components with liquid residues, the container 61 can be pulled out of the first avoiding port 101 along the longitudinal direction upward, and then the main body member 32 and the beauty head 31 can be pulled out of the mounting port 102 along the transverse direction rightward. At this time, the main body member 32, the beauty head 31, and the liquid outlet flow channel 1004 can be disassembled, cleaned, or replaced. After cleaning or taking new components, the main body member 32 and the beauty head 31 are inserted into the beauty instrument body 1 through the mounting port 102 along the transverse direction leftward, and then the container 61 is inserted into the main body member 32 through the first avoiding port 101 along the longitudinal direction downward, so as to complete the assembly work. Therefore, the beauty instrument provided by the embodiment can effectively solve the problem that the existing beauty instrument cannot clean or replace the delivery components of the essence liquid.

[0228] In the embodiment, please refer to Figure 2 and Figure 5 The main body member 32 comprises a main body bottom box 32a and a main body top cover 32b. The main body bottom box 32a is provided with a main body inner cavity 32a1 with an opening. 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 greater than the size of the liquid outlet flow channel 1004, so that the liquid outlet flow channel 1004 enters and exits 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 for covering 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 attracted and / or buckled, 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.

[0229] Optionally, the liquid outlet flow channel 1004 is a flexible pipe with variable shape, which is convenient to assemble and disassemble.

[0230] Please refer to Figure 6 and Figure 7The first communication part 111 is inserted into the second communication part 112, and the first communication part 111 is provided with an air inlet sealing ring 113.

[0231] In summary, the beauty instrument and the beauty kit provided by the embodiment have the following advantages:

[0232] ① By setting the first avoiding port 101 and the mounting port 102 on the beauty instrument body 1, the main body 32, the beauty head 31 and the liquid outlet channel 1004 can be disassembled from the beauty instrument body 1, so as to clean and replace the liquid delivery components such as the main body 32, the beauty head 31 and the liquid outlet channel 1004;

[0233] ② The main body bottom box 32a and the main body top cover 32b are detachably connected through buckle connection or magnetic attraction, so that the user can easily open the main body bottom box 32a, take out the liquid outlet channel 1004 and maintain and clean it, thereby enhancing the maintainability of the equipment;

[0234] ③ By setting 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 the gas delivery are ensured, so that the essence liquid can be uniformly and effectively pushed out to the beauty head 31.

[0235] [About the beauty head 31 and the negative pressure cavity 2]

[0236] In some embodiments, the beauty instrument further comprises a beauty component 3 arranged at one end of the beauty instrument body 1; wherein the beauty component 3 forms the negative pressure cavity 2; or the negative pressure cavity 2 is formed between the beauty instrument body 1 and the beauty component 3.

[0237] Optionally, the beauty head 31 can be arranged in various ways. One of the arrangement ways of the beauty head 31 is fixed arrangement. In specific installation, the beauty head 31 can be fixedly installed on the beauty instrument body 1, and the beauty instrument body 1 provides support effect for the beauty head 31. Figure 13 Alternatively, as shown in FIG. 1, the beauty head 31 can also be fixedly installed on the main body 32, and at this time, the beauty head 31 and the main body 32 form a modular structure, so as to realize production at one time.

[0238] The second setting mode of the beauty head 31 is detachable, for example, the beauty head 31 is detachably connected with the main body 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 part 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 specifically limited here. No matter what installation mode the beauty head 31 adopts, as long as any one of the above-mentioned schemes is adopted, it is included in the consideration range of the alternative means of the present scheme.

[0239] The following will be specifically described taking the fixed setting mode of the beauty head 31 as an example.

[0240] The beauty assembly 3 includes the main body 32 and the beauty head 31, the beauty head 31 is connected to one end of the main body 32 and exposed to the beauty instrument body 1.

[0241] Please refer to Figure 13 , the beauty head 31 is arranged on the main body 32, and the beauty head 31 is fixedly connected with the main body 32. In this way, the integrated production of the main body 32 and the beauty head 31 can be realized, for the convenience of description, the main body 32 and the beauty head 31 constitute the beauty assembly 3 which can be integrated and produced, and through the fixed installation mode, the structure of the beauty assembly 3 can be ensured stable and not easy to fall off. Refer to Figure 20 , to further prevent the reverse flow of the essence liquid into the second section of the negative pressure channel 4, the anti-backflow structure is arranged at the beauty head 31 in the embodiment. Specifically, the anti-backflow structure realizes the anti-backflow function by prolonging the path of the airflow in the negative pressure cavity 2.

[0242] In some embodiments, the negative pressure cavity 2 includes an outer cavity part 21 and an inner cavity part 22, the beauty head 31 includes a core 31a and a suction sleeve 31b, the inner cavity part 22 is formed inside the core 31a, and the suction sleeve 31b is sleeved outside the core 31a, the outer cavity part 21 in communication with the outside is formed between the core 31a and the suction sleeve 31b, and the core 31a is further provided with a through hole for communicating the outer cavity part 21 and the inner cavity part 22.

[0243] Specifically, please refer to Figure 20The core 31a is connected with the main body 32, the core 31a is hollow inside, and the inner cavity part 22 is formed inside the core 31a; the adsorption sleeve 31b is sleeved outside the core 31a, and the beauty component 3 further comprises a sealing ring 7 connected with the adsorption sleeve 31b and the core 31a respectively, thereby forming the outer cavity part 21 between the core 31a and the adsorption sleeve 31b, and one side of the adsorption sleeve 31b has an open structure, and the outer cavity part 21 can be communicated with the outside through the opening; in addition, the inner-outer communication hole 1001 is further arranged on the core 31a, the inner-outer communication hole 1001 can communicate the outer cavity part 21 with the inner cavity part 22, and the inner cavity part 22 is communicated with the second section of the negative pressure channel 4. The airflow needs to flow through the outer cavity part 21, the inner-outer communication hole 1001 and the inner cavity part before reaching the second section of the negative pressure channel 4, which prolongs the path of the airflow in the negative pressure cavity 2, and is beneficial to reduce the possibility of the essence being sucked into the second section of the negative pressure channel 4 after being output from the beauty head 31.

[0244] In some embodiments, continuing to refer to Figure 20 , based on the first negative pressure pipeline 41 and the second negative pressure pipeline 42 arranged as above, the negative pressure channel 4 comprises a first section for communicating the liquid storage cavity 6 and the outer cavity part 21, and a second section for communicating the inner cavity part with the negative pressure mechanism 5; the adsorption element 3123 is arranged on the core 31a and located in the outer cavity part 21 and connected with the first section of the negative pressure channel 4.

[0245] When the liquid storage cavity 6 is communicated with the outer cavity part 21, one end of the first negative pressure pipeline 41 is connected with the connecting part 33, and the other end is directly connected with the core 31a.

[0246] In some embodiments, the core 31a is provided with a core pipe 8, one end of the core pipe 8 is connected with the first section, and the other end of the core pipe 8 is communicated with the outer cavity part 21, so as to realize the communication between the liquid storage cavity 6 and the outer cavity part 21; in addition, one end of the second negative pressure pipeline 42 is connected with the negative pressure mechanism 5, and the other end is directly connected with the core 31a, and the core 31a is provided with an interface for airflow, and the second negative pressure pipeline 42 is communicated with the inner cavity part 22 through the interface.

[0247] Through the above setting, the negative pressure mechanism 5 is started, and the negative pressure mechanism 5 can form negative pressure at the inner cavity part through the negative pressure channel 4. At this time, the outer cavity part 21 is synchronously formed negative pressure under the action of the through hole. At this time, because the outer cavity part 21 is in communication with the outside world, when the beauty head 31 contacts the skin, the outer cavity part 21 will adsorb the skin, and the adsorption sleeve 31b in the sleeve structure can well form a negative pressure area on the skin surface, and the adsorption action is fast and efficient. At the same time, because the outer cavity part 21 has negative pressure, the negative pressure channel 4 will pump the essence liquid towards the outer cavity part 21, so that the essence liquid can be attached to the adsorption element 3123, and then applied to the skin. The setting of the outer cavity part 21, the inner-outer communication hole 1001 and the inner cavity part prolongs the path of the airflow. In this process, the essence liquid overflowing from the adsorption 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-reflux effect.

[0248] Specifically, please refer to Figure 20 The core body 31a includes a core seat 311, one side of the core seat 311 is connected with the main body piece 32, and the inside of the core seat 311 is hollow to form the inner cavity part 22. Specifically, the core seat 311 is a sleeve structure with one end closed, the closed end of the core seat 311 is connected with the main body piece 32, and is provided with the aforementioned interface in communication with the second negative pressure pipeline 42.

[0249] The core pipe 8 includes 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 part 22 in the internal space of the core seat 311 (that is, the pipe head 81 covers the opening of the inner cavity part 22). The pipe body 82 extends from one side of the pipe head 81 towards the inner cavity part 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 part 21 through the pipe penetrating hole 1007.

[0250] The inner-outer communication hole 1001 connecting the outer cavity part 21 and the inner cavity part 22 is formed in the core seat 311 and located on the side close to the closed end of the core seat 311, that is, the side close to the main body piece 32. This setting can prolong the distance between the inner-outer communication hole 1001 and the opening, thereby prolonging the flow path of the airflow in the outer cavity part 21. In addition, the core seat 311 is also provided with an extension pipe 313, which extends into the inner cavity part 22 at the interface connected with the second negative pressure pipeline 42, so as to communicate the negative pressure mechanism 5 with the inner cavity part 22. The end of the extension pipe 313 extending into the inner cavity part is located on the side away from the inner-outer communication hole 1001.

[0251] In this way, the flow path of the air flow in the inner cavity 22 can be further prolonged. The outer cavity 21, the inner-outer communication hole 1001, and the inner cavity 22 form a multi-bending flow path, which prolongs the flow path of the air flow in the outer cavity 21 and the inner cavity 22, and the path causes 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 adheres to the inner wall of the negative pressure cavity 2 due to inertia at the bending position, and thus the backflow prevention effect is further improved.

[0252] Further, referring to Figure 21 To realize the essence liquid application action, the beauty head 31 further includes a liquid outlet 1002 and an adsorption element 3123. The liquid outlet 1002 is in communication with the first section and is used to deliver the essence liquid to the skin. The adsorption element 3123 is arranged between the first section of the negative pressure passage 4 and the liquid outlet 1002 and is used to retain the essence liquid.

[0253] In one embodiment, the adsorption element 3123 is mounted on the core 31a, the adsorption element 3123 is located in the outer cavity 21 and is located at the outermost side of the core 31a, the core 31a is connected with the first section of the negative pressure passage 4, and the essence liquid can flow from the first section of the negative pressure passage 4 and the core pipe 8 directly into the adsorption element 3123.

[0254] Optionally, the adsorption element 3123 can be a sponge block, a porous silica gel block, or a porous ceramic block, etc. These materials have strong liquid absorption capacity due to their porous structure. They can absorb and retain a large amount of essence liquid, so that the essence liquid can be more uniform and continuous during delivery, and the use effect will not be affected by the instantaneous flow change.

[0255] In this embodiment, 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 and friendly to the skin, and the user can directly contact the sponge or the porous silica gel block with the skin to realize the liquid outlet function of the beauty head 31. In this embodiment, the sponge structure is adopted. The sponge has good liquid storage function and good rebound performance, and can provide good experience for the user when directly contacting the skin to apply the essence liquid.

[0256] Alternatively, in some other embodiments, to achieve the liquid storage function, the adsorption element 3123 can also be provided with a cavity for storing the essence liquid 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 provided on the core body 31a, which is 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 achieved. Therefore, the cavity can also be regarded as the adsorption element 3123. In this embodiment, the cavity for storing the essence liquid is directly formed in the core body 31a, which on the one hand helps to control the production and assembly cost, improves the production efficiency; on the other hand, it is also convenient for cleaning and improves the safety and health.

[0257] Further, please refer to Figure 22 To optimize the liquid outlet effect, in one of the embodiments, the core body 31a further comprises an application unit 3121, which is in a sleeve structure. 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, that is, the outermost side. The application unit 3121 is provided with a liquid outlet 1002, which is communicated with the pipe hole 1007 of the core seat 311.

[0258] Further, the adsorption element 3123 is arranged between the core seat 311 and the application unit 3121. Since the adsorption element 3123 is in an elastic structure, the application unit 3121 and the core seat 311 of the core body 31a can send the essence liquid out of the liquid outlet 1002 to the skin by extruding the adsorption element 3123. Through this arrangement, the liquid outlet amount can be controlled by changing the pressing force during use, and the use is more flexible and convenient.

[0259] Further, please refer to Figure 20 The core body 31a further comprises an elastic member 314, which is preferably in a spring structure. 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. 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 use convenience and skin experience are optimized and improved.

[0260] Further, in order to promote the absorption of the essence liquid, the application unit 3121 is further provided with micro-needles. Specifically, please refer to Figure 20The microneedle wafer 3122 can be installed at the outermost side of the application unit 3121, or the nanometer microneedle structure can be formed directly on the application unit 3121, that is, the application unit 3121 itself is a microneedle wafer 3122. Through the above arrangement, the nanometer microneedles on the application unit 3121 or the microneedle wafer 3122 can form micro channels on the skin by stimulating the skin, thereby promoting the absorption of the essence.

[0261] In some embodiments, the cosmetic head 31 further comprises a liquid outlet 1002 and a microneedle wafer 3122, the liquid outlet 1002 is arranged on the microneedle wafer 3122, the adsorption element 3123 is located between the microneedle wafer 3122 and the main body 32, and the adsorption element 3123 is connected with the negative pressure channel 4. In a specific arrangement, the liquid outlet 1002 is arranged on the microneedle wafer 3122, the microneedle wafer 3122 is connected to the main body 32 and located at the outermost side of the cosmetic head 31, the adsorption element 3123 is connected to the main body 32 and located between the microneedle wafer 3122 and the main body 32. In this arrangement, the microneedle wafer 3122 is indirectly arranged on the main body 32 through the adsorption element 3123, one side of the adsorption element 3123 is connected with the first section of the negative pressure channel 4, and the other side is connected with the liquid outlet 1002, and at this time the first section of the negative pressure channel 4 and the liquid outlet 1002 are communicated.

[0262] It can be understood that in the mode of installing the microneedle wafer 3122 at 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 microneedle wafer 3122, so that the essence can be smoothly transmitted from the adsorption element 3123 to the liquid outlet 1002.

[0263] Through the above arrangement, the essence can flow directly into the adsorption element 3123, the microneedle wafer 3122 can stimulate the skin because it is located at the outermost side of the cosmetic head 31, and in this process, the microneedle wafer 3122 can squeeze the adsorption element 3123, so that the essence flows out from the liquid outlet 1002. While applying the essence, the essence can penetrate into the skin from the micro channels formed by the microneedle wafer 3122, thereby improving the absorption of the essence.

[0264] In other embodiments, the liquid outlet 1002 can also not be arranged on the microneedle wafer 3122, the cosmetic head 31 comprises a microneedle wafer 3122, the microneedle wafer 3122 is connected with the main body 32, the adsorption element 3123 is connected with the main body 32 and adjacent to the microneedle wafer 3122, the adsorption element 3123 is connected with the negative pressure channel 4, and the opening of the porous structure of the adsorption element 3123 outward forms the liquid outlet 1002.

[0265] Specifically, the microneedle wafer 3122 and the adsorption element 3123 are connected with the main body 32 and arranged adjacently, the adsorption element 3123 is connected with 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.

[0266] [Optimization of essence application]

[0267] 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, so as to apply the essence to the skin. This manner has the problems of small amount of essence application and unevenness. In order to make the application of essence more uniform, the permeability higher, and the use experience of the beauty instrument better, the beauty instrument of the embodiment further comprises a vibration mechanism 9 for driving the beauty head 31 to reciprocate.

[0268] Referring to Figure 3 , Figure 23 and Figure 24 , in an embodiment, the vibration mechanism 9 is arranged in the beauty instrument body 1 and comprises a vibration motor 91. The vibration motor 91 is arranged in the beauty instrument body 1 and is in transmission connection with the beauty head 31 to drive the beauty head 31 to reciprocate. The beauty instrument can not only stably apply essence but also massage the skin to promote the absorption of essence, so as to improve the application accuracy, the uniformity of application effect, and 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. Optionally, 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.

[0269] In another embodiment, the beauty head 31 can be directly connected with the vibration motor 91, i.e., the beauty head 31 can be directly connected with the vibration motor 91 without arranging the main body 32. This setting structure is simple and has 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 with the vibration motor 91 to facilitate replacement of the beauty head 31.

[0270] Please refer to Figure 23 and Figure 24 , and the following embodiment will be described by taking the embodiment in which the beauty head 31 is in transmission connection with the vibration mechanism 9 through the main body 32 as an example.

[0273] In this embodiment, the vibration mechanism 9 can be connected to the main body 32 in two ways.

[0278] Specifically, in the arrangement of the beauty kit using the container 61 to store the essence liquid, the vibration connecting piece 92 of the beauty instrument is further provided with the second avoiding opening 921, the second avoiding opening 921 is used for exposing the connecting part 33 of the main body piece 32 for the disassembly and assembly of the container 61, under the above structure arrangement, the vibration motor 91 can drive the vibration connecting piece 92 to reciprocate, and meanwhile, the disassembly and assembly of the container 61 can be met, more importantly, the user can disassemble the whole main body piece 32, at this time, liquid can be avoided to remain in the negative pressure channel 4 of the main body piece 32, that is, 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 safety and health are ensured.

[0279] It needs to be explained that the vibration connecting piece 92 can be arranged outside the beauty instrument body 1 when arranged, at this time, the second avoiding opening 921 can be arranged to expose the connecting part 33, but in order to meet the needs of stable and compact structure, reference is made to Figure 23 and combination Figure 2 In some embodiments, the vibration connecting piece 92 is arranged in the beauty instrument body 1, the beauty instrument body 1 is provided with a mounting opening 102 for the disassembly and assembly of the main body piece 32, the beauty instrument body 1 is provided with a first avoiding opening 101 corresponding to the second avoiding opening 921, the length of the first avoiding opening 101 in the vibration direction of the main body piece 32 is greater than the length of the second avoiding opening 921 in the vibration direction of the main body piece 32.

[0280] Specifically, the vibration connecting piece 92 is arranged in the beauty instrument body 1, one end of the beauty instrument body 1 is provided with the mounting opening 102 for the disassembly and assembly of the main body piece 32, the mounting opening 102 can enable the beauty component 3 to be mounted to the inside of the beauty instrument body 1, and the mounting opening 102 plays an avoiding role and is used for the disassembly and assembly of the beauty component 3, correspondingly, the first avoiding opening 101 of one side of the beauty instrument body 1 corresponds to the second avoiding opening 921, and the container 61 can be detachably connected to the connecting part 33 in sequence through the first avoiding opening 101 and the second avoiding opening 921.

[0281] Moreover, the length of the first avoiding opening 101 in the vibration direction of the main body piece 32 is greater than the length of the second avoiding opening 921 in the vibration direction of the main body piece 32, so as to avoid the vibration interference between the container 61 and the beauty instrument body 1 when the container 61 vibrates with the beauty component 3.

[0282] Reference is made to Figure 24In the case of dismounting and connecting the main body 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 to avoid air leakage during the dismounting and connecting process. The vibration connecting piece 92 is provided with a communication part 11, which has a connecting channel, and the negative pressure mechanism 5 communicates with the negative pressure channel 4 through the communication part 11

[0283] In some embodiments, the vibration connecting piece 92 is provided with the aforementioned communication part 11, which has a column tube structure, and the two ends of the communication part 11 extend to the outside and the inside of the vibration connecting piece 92, respectively. Meanwhile, the hollow part of the communication part 11 forms a connecting channel, and the negative pressure mechanism 5 communicates with the negative pressure channel 4 through the communication part 11.

[0284] In a specific arrangement, the multi-way valve 54 and the outside of the communication part 11 are connected by adding a pipe between the negative pressure mechanism 5 and the communication part 11, and the main body 32 also has a notch structure that is inserted and positioned with the inside segment of the communication part 11. The bottom of the notch structure has a through hole, and the second segment of the negative pressure channel 4 communicates with the connecting channel through the through hole. For the convenience of distinction, the notch on the main body 32 is defined as the first communication part 111, and the communication part 11 on the vibration connecting piece 92 is defined as the second communication part 112. Based on this arrangement, the main body 32 and the vibration connecting piece 92 can be inserted and positioned through the communication part 11 and the notch, and at the same time, the negative pressure channel 4 and the negative pressure mechanism 5 can be quickly connected, which is convenient to use and not easy to leak.

[0285] In other embodiments, the second communication part 112 can also be arranged as a notch structure, which requires a corresponding protruding structure to be arranged on the main body 32. Through the method of insertion and positioning, the negative pressure channel 4 and the negative pressure mechanism 5 can be connected in the dismounting state of the main body 32. It can be understood that the structures of the first communication part 111 and the second communication part 112 are arranged in reverse. No matter which way is adopted, the insertion and positioning scheme that can realize the accurate butt joint and connection of the main body 32 and the vibration connecting piece 92 should be regarded as the same means of this scheme.

[0286] Further, with reference to Figure 25 To realize the convenient dismounting between the vibration connecting piece 92 and the main body 32, the vibration connecting piece 92 is provided with an elastic buckle 922, and the main body 32 is provided with a buckle part 923 that is movably buckled with the elastic buckle 922.

[0287] Specifically, the vibration connecting piece 92 is provided with an elastic buckle 922. An accommodating opening can be formed on the circumferential side of the vibration connecting piece 92, and the elastic buckle 922 is located in the accommodating opening, so that the structural compactness is improved. Correspondingly, a buckling portion 923 that is movably buckled with the elastic buckle 922 is arranged at the corresponding position of the main body piece 32. The elastic buckle 922 is provided with a barb, and the buckling portion 923 is in a recess structure. Under the action of the elastic buckle 922 and the buckling portion 923, the main body piece 32 and the vibration connecting piece 92 can be quickly plugged and installed, the operation is convenient, and a clear stop feeling is generated during assembly, so that the user can feel whether the assembly is in place, and the use experience is good.

[0288] It should be explained that the arrangement positions of the elastic buckle 922 and the buckling portion 923 can be transposed, for example, the elastic buckle 922 is arranged on the main body piece 32, and the buckling portion 923 is arranged on the elastic connecting piece, and the mutual buckling effect can also be achieved. In addition, the two can also be connected and detached in a magnetic attraction mode or a threaded connection mode. The structures that can be connected and detached can be tried to be used, and should be included in the explanation range of the detachable connection.

[0289] [Refined setting of the beauty head 31]

[0290] Further, referring to Figure 26 Based on the above structure, the beauty head 31 and the beauty instrument of the embodiment can further optimize the uniform liquid feeding effect of the beauty head 31.

[0291] Firstly, the use process of the beauty instrument is introduced by taking that the essence liquid is stored in the container 61 as an example:

[0292] 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. Then, under the action of the pressure difference, the essence liquid in the container 61 is transported to the beauty head 31 through the liquid outlet flow channel 1004, and is transported to the human skin through the liquid outlet 1002 of the beauty head 31.

[0293] S20: The vibration mechanism 9 drives the beauty head 31 to perform micro-distance vibration in the front-back direction. During the vibration process of the beauty head 31, the human skin is continuously stimulated, so that the absorption of the essence liquid by the human skin is promoted.

[0294] Optionally, the vibration mechanism 9 can be a cam connecting rod mechanism, or a linear driving mechanism, and the like. The embodiment does not limit the vibration mechanism 9. Further, the linear driving mechanism can be a gas cylinder, a hydraulic cylinder, an electric cylinder or a motor screw linear module.

[0295] To optimize the cosmetic effect of the cosmetic head 31, the following further detailed description is made for the cosmetic head 31 in the present embodiment.

[0296] With reference to Figure 27 The cosmetic head 31 provided by the present embodiment includes a core pipe 8, a liquid outlet component 312, and an adsorption element 3123. The core pipe 8 is provided with a liquid delivery hole 821 in the pipe. The liquid outlet component 312 is connected with the core pipe 8 and cooperates with the core pipe 8 to form a closed buffer cavity 1006; wherein the liquid outlet component 312 is provided with a liquid outlet 1002 that communicates the buffer cavity 1006 to the external space of the cosmetic head 31. The adsorption element 3123 has a porous structure, and the adsorption element 3123 is located in the buffer cavity 1006.

[0297] The cosmetic head 31 and the cosmetic instrument provided by the present embodiment have the following advantages. On the one hand, when the liquid delivery hole 821 in the pipe delivers the essence liquid into the buffer cavity 1006, the essence liquid will first enter the internal holes of the adsorption element 3123, and when the internal holes of the adsorption element 3123 are filled with the essence liquid, the essence liquid will flow out of the liquid outlet 1002. In this process, the adsorption element 3123 has a porous structure and a large liquid storage space, which can temporarily store the essence liquid, thereby adjusting the speed and amount of the essence liquid flowing out of the liquid outlet 1002. In this way, even if the supply amount of the essence liquid through the liquid delivery hole in the pipe fluctuates, the cosmetic head 31 can ensure that the flow rate of the essence liquid delivered out of the liquid outlet is relatively stable, thereby avoiding the problem of uneven or discontinuous delivery of the essence liquid caused by the change in the supply amount.

[0298] 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 a large amount of essence liquid flowing out of the liquid outlet 1002 directly, which can cause the essence liquid to be wasted when the outer cavity portion 21 is directly sucked back by the negative pressure mechanism 5.

[0299] Optionally, the core pipe 8 and the liquid outlet component 312 are in sliding sealing connection, and the buffer cavity 1006 is further provided with a spring 3141 that abuts against the core pipe 8 and the liquid outlet component 312, respectively; wherein the spring 3141 is used to drive the liquid outlet component 312 to move away from the adsorption element 3123.

[0300] The design of the spring 3141 enables the cosmetic head 31 to automatically adjust the liquid outlet amount according to the pressure of the skin contact. Specifically, the spring 3141 balances the internal and external pressures, and when the external pressure decreases, the spring 3141 pushes 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, which is not affected by the user's operation force.

[0301] Optionally, the number of springs 3141 is one, and the adsorption element 3123 is located in the hollow space of the spring 3141. When the number of springs 3141 is one, the adsorption element 3123 is located in the hollow space of the spring 3141. Such a layout can effectively utilize space and improve the structural compactness of the beauty head 31.

[0302] Alternatively, the number of springs 3141 is at least two, and each spring 3141 is uniformly arranged around the adsorption element 3123. For example, the number of springs 3141 is two, and the two springs 3141 are symmetrically arranged about the adsorption element 3123; or the number of springs 3141 is three, and 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, and the four springs 3141 are arranged in a square, and the adsorption element 3123 is located at the center of the square, etc. Uniformly arranging multiple springs 3141 can provide more stable support and pressure balance, ensuring uniform output of the essence liquid.

[0303] In this embodiment, the beauty head 31 further includes 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.

[0304] Correspondingly, the core pipe 8 includes 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.

[0305] 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 in the buffer cavity 1006 through the liquid outlet flow channel 1004 and the liquid-in pipe hole 821.

[0306] In this embodiment, the liquid outlet component 312 includes an application unit 3121 provided with an opening slot, and a microneedle wafer 3122 located on the side of the application unit 3121 away from the adsorption element 3123; 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.

[0307] The head of the core tube 8 is inserted into the opening slot, wherein the core tube 8, the slot wall of the opening slot, and the slot bottom of the opening slot surround to form the buffer cavity 1006. Further, the circumferential surface of the head of the core tube 8 is sleeved with the sealing piece 315 abutting against the slot wall of the opening slot.

[0308] The opening slot design allows the core tube 8 to be inserted and form the 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 to penetrate the skin more deeply through the tiny needle holes.

[0309] 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 opening 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 to limit the core tube 8 from being separated from the application unit 3121 through the slot opening of the opening 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, ensuring the stability of the relative position between the two, thereby ensuring the stability of the essence delivery.

[0310] In summary, the cosmetic head 31 and the cosmetic instrument provided by the embodiment have the following advantages after being combined with the vibration mechanism 9:

[0311] 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, thereby ensuring the uniformity and stability of the essence delivery, but also control the liquid outlet amount in a negative pressure environment, prevent the essence from being sucked by the negative pressure mechanism 5, and reduce waste;

[0312] ②The design of the spring 3141 enables the cosmetic head 31 to automatically adjust the liquid outlet amount according to the skin contact pressure, ensuring the stable delivery of the essence;

[0313] 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, facilitating assembly and maintenance.

[0314] [Sealing arrangement of the negative pressure cavity 2]

[0315] 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 also discloses a sealing scheme, which can meet the effect of stable adsorption under vibration conditions.

[0316] Reference Figure 28The cosmetic instrument scheme includes the core body 31a, the adsorption sleeve 31b and the sealing ring 7. 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 and vibrate, 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 details are not repeated 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, and the specific setting mode is not repeated here.

[0317] The core body 31a is arranged in the adsorption sleeve 31b, and a negative pressure cavity 2 in communication with the negative suction channel is formed between the core body 31a and the adsorption sleeve 31b. The negative pressure cavity 2 is used to communicate 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, so as to form a negative pressure area in the negative pressure cavity 2 which can adsorb the skin.

[0318] It can be understood that in order to obtain appropriate adsorption strength, the air pressure of the negative pressure area is controlled in the range of-20kpa to-40kpa, and the specific value can be selected as-20kpa, -30kpa or-40kpa, etc. 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 of the user, the air pressure of-20kpa can be used for adsorption, so that smaller adsorption strength 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 strength is moderate, which is suitable for most users' skin quality. 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 during use, such as users with oily skin. 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 actual design, which is not limited here.

[0319] Furthermore, in the process of negative pressure adsorption, 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 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.

[0320] Optionally, the thickness of the adsorption sleeve 31b can be set according to the skin quality requirements, for example, sensitive skin users are suitable for a thickness of 2.8mm, at this time, the thickness can be increased to reduce the pressure on the skin during adsorption, 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, and suitable for most users. When the thickness of the adsorption sleeve 31b is set to 0.8mm, a greater pressure can be generated on the skin during the adsorption process, thereby more stably adsorbing the skin, suitable for oily skin users, and not easy to deviate during adsorption.

[0321] Optionally, the chamfer can also be adjusted according to the thickness of the adsorption sleeve 31b, the chamfer is preferably a single chamfer structure, which can adopt a circular chamfer structure, and the chamfer is as large as possible under the limitation of the thickness, only a part of the plane needs to be reserved, for example, when the thickness of the adsorption sleeve 31b is set to 0.8mm, the size of the chamfer is selected to be 0.3mm, when the thickness of the adsorption sleeve 31b is 1.4mm, the size of the chamfer is 0.5mm, and when the thickness of the adsorption sleeve 31b is 2.8mm, the size of the chamfer is 0.8mm.

[0322] The above values are not limited in combination. After the adsorption sleeve 31b adopts the above thickness range and chamfer range, a contact surface with an arc can be formed, so that the adsorption does not leave marks, and the skin feeling is optimized and improved.

[0323] Referring to Figure 28 and Figure 29 In an embodiment, the sealing ring 7 is located between the core 31a and the adsorption sleeve 31b in the present 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, and further, the sealing ring 7 has an elastic deformation part 73, which is used to provide elastic buffering for the core 31a and the adsorption sleeve 31b.

[0324] 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 setting the elastic deformation part 73 on the sealing ring 7, the elastic deformation part 73 can give the sealing ring 7 elastic stretching and contraction freedom, at this time, 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 does not easily leak air during vibration, and further, the impact force of the adsorption sleeve 31b on the skin during vibration can be reduced, and a better experience can be provided.

[0325] Meanwhile, 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 generally includes three position states. In the first position state, the core 31a does not exceed the opening of the adsorption sleeve 31b. In the second position state, the end face of the core 31a is flush with the opening. In the third position state, 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, the skin 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 above three setting states are adopted between the core 31a and the adsorption sleeve 31b.

[0326] Preferably, in the embodiment, the first position state is set, and the distance between the microneedle wafer 3122 and the opening of the adsorption sleeve 31b is controlled to be 0.5mm-1.5mm, and can be 0.5mm, 1mm or 1.5mm. The distance between the microneedle wafer 3122 and the opening of the adsorption sleeve 31b should be set according to the stimulation degree of the user. It can be known that the greater the opening distance between the two, the greater the movement stroke of the microneedle, and the longer the stroke will make the compression degree of the elastic member 314 greater, and thus the force on the skin is greater. Therefore, on the one hand, different pain will be produced, and on the other hand, redness and swelling phenomenon may occur on sensitive skin.

[0327] Based on this, when the distance between the microneedle wafer 3122 and the opening of the adsorption sleeve 31b is set to 0.5mm, the stimulation degree can be reduced, thereby meeting the use demand of users with low pain tolerance and sensitive skin. In addition, when the distance between the microneedle wafer 3122 and the opening of the adsorption sleeve 31b is set to 1mm, the stimulation degree is moderate, which is suitable for most user demands. Furthermore, when the distance between the microneedle wafer 3122 and the opening of the adsorption sleeve 31b is set to 1.5mm, it can be used for piercing for users with thick stratum corneum, so as to achieve deep penetration of essence and optimize the beauty effect.

[0328] Under the above distance setting, the distance is adjusted according to different demands, so that the skin can just contact the microneedle wafer 3122 after negative pressure adsorption. Combined with the vibration effect of the vibration mechanism 9, the pain and discomfort caused by excessive piercing force can be reduced in the case of piercing the skin. The massage degree is moderate, the skin feeling is optimized, and the specific distance value in actual setting is not limited here.

[0329] Specifically, in one embodiment, the elastic deformation part 73 can be formed of a soft elastic material, such as a silicone rubber structure. In this case, the elastic deformation part 73 has elastic expansion and contraction effects, and can provide sealing and elastic buffering functions to meet the use conditions.

[0330] It should be explained that if the material of the elastic deformation part 73 is simply changed, the sealing ring 7 itself can also have the possibility of disordered deformation. For example, in actual application, the adsorption sleeve 31b not only vibrates linearly along the axis of vibration, but also is subjected to a vertical displacement perpendicular to the axis of vibration due to the user's operation, such as moving the adsorption position. In this case, if the structure of the elastic deformation part 73 is a conventional straight cylinder structure, it can cause transverse deformation and thus cause air leakage.

[0331] Referring to Figure 29 To overcome the above technical difficulties, in the present embodiment, the elastic deformation part 73 includes a corrugated segment 731 bent towards one side, and the corrugated segment 731 is arranged in a closed loop along the circumferential direction of the sealing ring 7 to form a telescopic structure similar to a telescopic joint. In this case, the corrugated segment 731 can provide certain support to the elastic deformation part 73 to reduce the tendency of vertical deformation, and the bent segment can provide vibration guidance to the sealing ring 7, so that it can better withstand the elastic buffering force, and the vibration sealing property is guaranteed.

[0332] It can be understood that the corrugated segment 731 can be arranged in a plurality of adjacent combinations during actual arrangement. A single corrugated segment 731 can be bent towards the inside or the outside, and the specific bending direction can be adjusted according to actual needs. In the present embodiment, the inward bending mode is used as an example for illustration. The inward bending mode is beneficial to the assembly of the sealing ring 7 in a small space. In addition, in another embodiment, the corrugated segment 731 can also be replaced by other similar structures, such as a sawtooth structure. Structures that can achieve telescopic buffering can be used, and should be included in the protection scope of the present application.

[0333] Further, referring to Figure 30 and Figure 31In another embodiment, in order to optimize the elastic deformation part 73 against deformation resistance perpendicular to the vibration direction, the elastic deformation part 73 further comprises a reinforcing section 732, which is recessed towards the inside of the sealing ring 7, and in this embodiment, the inwardly recessed structure is adopted. Based on the above arrangement, the reinforcing section 732 causes the elastic deformation part 73 to form a first stepped surface 733 and a second stepped surface 734 at the outer peripheral surface, the reinforcing section 732 between the first stepped surface 733 and the second stepped surface 734 being perpendicular to the vibration direction, so as to provide a stable anti-vertical deformation effect, so that the adsorption sleeve 31b can further stably vibrate along the vibration direction, the structure is not easy to loosen, and the adsorption effect is optimized and improved.

[0334] It can be understood that the reinforcing section 732 can be provided in multiple groups, and different reinforcing sections 732 can be selectively provided in the elastic deformation part 73 in the form of outwardly or inwardly bent, and can be arbitrarily combined to provide the anti-vertical deformation function. In this embodiment, only one reinforcing section 732 is shown, and the reinforcing section 732 is recessed towards the inside.

[0335] In addition, with reference to Figure 31 The thickness of the intersection of the first stepped surface 733 and the second stepped surface 734 can also be set to be greater than the thickness of the area where the first stepped surface 733 or the second stepped surface 734 is located, which is equivalent to thickening the recessed position of the reinforcing section 732. At this time, the structural strength of the reinforcing section 732 can be further optimized and improved.

[0336] Continuing to refer to Figure 30 and Figure 31 In order to optimize the overall sealing performance of the sealing ring 7, the connection stability between the sealing ring 7 and the core 31a and the adsorption sleeve 31b is also an important influencing factor.

[0337] Therefore, the sealing ring 7 is made of silica gel or rubber material, and when the sealing ring 7 is connected with the core 31a, the sealing ring 7 comprises a first connecting part 71 connected with the elastic deformation part 73. Generally, the two are integrally connected to obtain good sealing performance. Furthermore, the first connecting part 71 comprises a first lamination section 711 fixedly wrapped around the outer peripheral surface of the core 31a. At this time, the first lamination section 711 is connected to the outer peripheral surface of the core 31a by elastic wrapping or adhesive wrapping, so as to obtain a stable connection relationship and good sealing performance.

[0338] Further, based on the first lamination section 711, the first connecting part 71 further comprises a first extension section 712 connected with the first lamination section 711, and the first extension section 712 is extended and fixedly wrapped around the end surface of the core 31a. At this time, the first extension section 712 can further increase the wrapping performance, and further optimize the sealing performance of the first connecting part 71.

[0339] Further, continuing to refer to Figure 31 In the process of connecting the sealing ring 7 with the adsorption sleeve 31b, the sealing ring 7 further comprises a second connecting portion 72 connected with the elastic deformation portion 73, the second connecting portion 72 is located on the side of the sealing ring 7 away from the first connecting portion 71, and the second connecting portion 72 is usually integrally connected with the elastic deformation portion 73 to obtain good sealing performance; further, the second connecting portion 72 comprises a second bonding segment 721 fixedly attached to the outer circumferential surface or the inner circumferential surface of the adsorption sleeve 31b, and in this embodiment, the second connecting portion 72 is attached to the outer circumferential surface of the adsorption sleeve 31b.

[0340] At this time, the second connecting portion 72 is fixedly attached to the outer circumferential surface or the inner circumferential surface of the adsorption sleeve 31b to realize the mutual connection between the two, and such arrangement can have a larger contact area, thereby obtaining better sealing effect.

[0341] Further, in order to optimize the sealing performance between the sealing ring 7 and the core 31a, the sealing ring 7 can also be matched with the main body 32, and specifically, the main body 32 is used to connect the core 31a and the vibration mechanism 9; wherein the main body 32 is sleeved with the core 31a, and in this embodiment, the opening of the main body 32 is larger than the size of the end surface of the core 31a, so that the main body 32 can be sleeved to the outside of the core 31a; further, the first connecting portion 71 is located between the main body 32 and the core 31a, and the opposite surfaces of the first connecting portion 71 are respectively connected with the main body 32 and the core 31a, at this time, the first connecting portion 71 is equivalent to being clamped between the main body 32 and the core 31a, and such arrangement increases the number of sealing surfaces, which can further improve the overall sealing performance of the sealing ring 7.

[0342] Further, the first sealing protrusion 713 can also be arranged on the core 31a or the first connecting portion 71, and in this embodiment, the first sealing protrusion 713 has a closed loop structure, and because the sealing ring 7 adopts a structure of silica gel or rubber with elasticity, at this time, the first sealing protrusion 713 can block the gap between the first connecting portion 71 and the core 31a, and the sealing performance between the core 31a and the sealing ring 7 is optimized and improved.

[0343] It can be understood that the first sealing protrusion 713 can be arranged in multiple, and a single first sealing protrusion 713 can be selectively arranged on the core 31a or the first connecting portion 71, therefore, under the condition of multiple first sealing protrusions 713, the first sealing protrusion 713 is arranged on the core 31a and the connecting portion 33 respectively, and in this embodiment, the combination mode of the first sealing protrusion 713 is not limited, and no matter what combination is adopted, it should be included in the interpretation range of the present application.

[0344] Further, the second sealing protrusion 722 is arranged on the second connecting portion 72 and / or the adsorption sleeve 31b, and the second sealing protrusion 722 is arranged in a similar manner to the first sealing protrusion 713, and details are not repeated here. It can be understood that the second sealing protrusion 722 can block the gap between the second connecting portion 72 and the adsorption sleeve 31b, so as to increase the sealing performance between the core 31a and the second connecting portion 72.

[0345] With reference to Figure 32 And Figure 33 In another embodiment, the sealing ring 7 can also be arranged at other positions, for example, the sealing ring 7 can cooperate with the vibration mechanism 9, the beauty component 3 and the like, and thus another sealing structure is obtained.

[0346] In the embodiment, the beauty instrument includes a beauty instrument body 1, a vibration mechanism 9, a beauty component 3 and a sealing ring 7. One end of the beauty instrument body 1 is provided with a negative pressure sleeve 1a, and the negative pressure sleeve 1a has an opening. The negative pressure sleeve 1a is equivalent to replace the adsorption sleeve 31b in the foregoing. The vibration mechanism 9 is arranged on the beauty instrument body 1, the beauty component 3 is connected with the vibration mechanism 9, the vibration mechanism 9 can drive the beauty component 3 to reciprocate, the vibration mechanism 9 is used to drive the beauty component 3 to reciprocate, the negative pressure sleeve 1a is sleeved outside the beauty instrument, and the beauty component 3 is located in the negative pressure sleeve 1a.

[0347] It can be understood that the arrangement of the beauty component 3 in the negative pressure sleeve 1a includes three position relationships between the beauty component 3 and the negative pressure sleeve 1a. In the first position state, the end of the beauty component 3 does not exceed the opening of the negative pressure sleeve 1a. In the second position state, the end surface of the beauty component 3 is flush with the opening. In the third position state, the beauty component 3 slightly exceeds the opening of the beauty component 3. In the above three position relationships, the negative pressure sleeve 1a can more stably adsorb the skin.

[0348] Further, the sealing ring 7 is made of a material such as silica gel or rubber, which has elasticity. The sealing ring 7 includes a first connecting portion 71, an elastic deformation portion 73 and a second connecting portion 72 connected in sequence in the vibration direction. Preferably, the first connecting portion 71, the elastic deformation portion 73 and the second connecting portion 72 are integrally connected, so as to ensure that the sealing ring 7 has good sealing performance.

[0349] It can be understood that in this scheme, the elastic deformation portion 73 includes a corrugated segment 731 bent towards the inside and / or the outside. Optionally, 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 repeated here.

[0350] The first connecting part 71 is connected with the cosmetic component 3, and the second connecting part 72 is connected with the cosmetic instrument 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 the negative pressure cavity 2 between the negative pressure sleeve 1a and the cosmetic component 3.

[0351] In the above technical solution, the elastic deformation part 73 on the sealing ring 7 can adapt the sealing ring 7 to elastic deformation, thereby meeting the sealing function in a vibration environment and solving the problem of insufficient sealing in a vibration condition.

[0352] Optionally, referring to Figure 33 In one embodiment, the first connecting part 71 includes a first sealing branch 714, the first sealing branch 714 extends towards the cosmetic component 3, the first sealing branch 714 is perpendicular to the vibration direction, and the end of the first sealing branch 714 is connected with the circumferential side of the cosmetic component 3, at this time, the end surface of the first sealing branch 714 and the cosmetic component 3 form a sealing surface, achieving the sealing effect.

[0353] Optionally, in another embodiment, the first sealing branch 714 is also perpendicular to the vibration direction, and instead of the end contact mode, the position of the cosmetic component 3 can be adjusted, and the first sealing branch 714 is wrapped around the end surface of the cosmetic component 3 to form a sealing surface, at this time, the first sealing branch 714 can achieve the sealing effect through the end surface contact or the wrapping end surface setting mode, in this embodiment, the first sealing branch 714 extends towards the cosmetic component 3, and the end of the first sealing branch 714 is connected with the circumferential side of the cosmetic component 3.

[0354] Further, the first connecting part 71 also includes a second sealing branch 715, in this embodiment, the second sealing branch 715 is arranged adjacent to the first sealing branch 714, and one end of the first sealing branch 714 and one end of the second sealing branch 715 are connected with each other and connected with the elastic deformation part 73, and the difference between the first sealing branch 714 and the second sealing branch 715 is that the extension direction of the second sealing branch 715 is the same as the vibration direction, and the second sealing branch 715 is wrapped around the circumferential side of the vibration mechanism 9,

[0355] At this time, the second sealing branch 715 can improve the connection stability of the first connecting part 71 on the one hand, and on the other hand, the second branch forms an additional sealing surface with the vibration mechanism 9, further enhancing the sealing effect of the first connecting part 71, and the function is optimized and improved.

[0356] Further, in order to optimize the connection stability of the second sealing arm 715, the side of the vibration mechanism 9 is provided with a fitting step for the second sealing arm 715 to fit in, so that the sealing ring 7 can be more accurately connected with the vibration mechanism 9 during assembly, and the connection accuracy and stability between the sealing ring 7 and the vibration mechanism 9 can be improved, which is beneficial to improve the sealing effect.

[0357] In this embodiment, the end of the first sealing arm 714 is connected with the cosmetic assembly 3, and the side surface of the first sealing arm 714 can also be attached to the end surface of the vibration mechanism 9, thereby forming an additional sealing surface, improving the sealing effect, and the vibration mechanism 9 can provide support for the first sealing arm 714, so that the first sealing arm 714 is not easy to deform during vibration, thereby preventing air leakage.

[0358] Continuing to refer to Figure 32 and Figure 33 In order to meet the connection stability and sealing effect of the second connection part 72, the cosmetic instrument body 1 has an inner end surface perpendicular to the vibration direction of the cosmetic assembly 3. In this embodiment, the second connection part 72 includes a first sealing section 723 connected with the elastic deformation part 73, and the first sealing section 723 extends along the direction perpendicular to the vibration direction and is attached to the inner end surface, thereby realizing the connection between the second connection part 72 and the cosmetic instrument body 1. At this time, the second connection part 72 serves as a support for the sealing ring 7, forming a fulcrum, and can meet the vibration sealing effect of the sealing ring 7.

[0359] However, it should be noted that the sealing ring 7 is close to the depth of the cosmetic instrument body 1, so the deformation space of the elastic deformation part 73 needs to be considered to meet the requirement of freedom of movement. By adjusting the size of the cosmetic assembly 3 and the length of the vibration mechanism 9, an interval can be formed between the cross section of the cosmetic assembly 3 and the cosmetic body along the vibration direction, and the elastic deformation part 73 is located in the interval, so that the elastic deformation part 73 has a space for elastic buffering.

[0360] Further, in order to improve the connection stability between the second connection part 72 and the cosmetic instrument body 1, the cosmetic instrument body 1 further has an inner peripheral surface connected with the inner end surface, and the two are perpendicular to each other; the second connection part 72 further includes a second sealing section 724 connected with the first sealing section 723, and the two are integrally connected; the second sealing section 724 is attached to the inner peripheral surface, thereby widening the contact area between the second connection part 72 and the cosmetic instrument body 1, so that the sealing ring 7 is more stable and firm during assembly, and is not easy to come off and leak air.

[0361] In the above structure, a sealing structure is obtained, which is close to the inside of the beauty instrument body 1 and can provide elastic support, can form a larger negative pressure cavity 2, and meet the needs of different beauty instrument products under different use conditions. However, there are many sealing structures that can achieve the above functions. Here, another structure that can achieve the vibration sealing effect is provided, which is also close to the inside of the beauty instrument body 1.

[0362] Referring to Figure 34 And Figure 35 Specifically, the difference between the structure is that the structure of the first connecting part 71 and the second connecting part 72 is different, wherein the first connecting part 71 is located between the beauty component 3 and the vibration mechanism 9, and the opposite surfaces of the first connecting part 71 are respectively connected with the beauty component 3 and the vibration mechanism 9. Through this setting, the first connecting part 71 is clamped and assembled between the two, forming a laminated sealing structure, and the sealing effect is further optimized and improved.

[0363] Further, the beauty component 3 has a stepped surface 1009 opposite to the end surface of the vibration mechanism 9. At this time, the stepped surface 1009 can be obtained by setting a stepped structure at the main part 32 of the beauty component 3. And the first connecting part 71 includes a first bending section 716 and a second bending section 717, the second bending section 717 is connected with the elastic deformation part 73, the first bending section 716 is located on the side of the second bending section 717 away from the elastic deformation part 73, the first bending section 716 and the second bending section 717 are integrally connected, the extension direction of the first bending section 716 is parallel to the vibration direction, and the extension direction of the second bending section 717 is perpendicular to the vibration direction.

[0364] Therefore, the opposite surfaces of the first bending section 716 are respectively connected with the beauty component 3 and the vibration mechanism 9, and the second bending section 717 is respectively fitted with the end surface of the vibration mechanism 9 and the stepped surface 1009. Here, by setting the first connecting part 71 as the first bending section 716 and the second bending section 717, a bending sealing structure is formed, which is equivalent to forming two sealing structures, which can prolong the sealing path and improve the sealing effect.

[0365] In combination with Figure 36Further, in order to improve the connection sealing between the first connecting part 71 and the cosmetic assembly 3, the cosmetic assembly 3 and / or the first connecting part 71 is provided with a first sealing protruding ring 718, which has multiple setting modes, in the first setting mode, the first sealing protruding ring 718 is only arranged on the cosmetic assembly 3, at this time, the first sealing protruding ring 718 abuts against the first connecting part 71, in the second setting mode, the first sealing protruding ring 718 is only arranged on the first connecting part 71, at this time, the first sealing protruding ring 718 abuts against the cosmetic assembly 3, in the third setting mode, the first sealing protruding ring 718 is arranged in multiple groups and arranged on the first connecting part 71 and the cosmetic assembly 3 respectively, the above-mentioned combination mode is not limited in actual setting process, the first sealing protruding ring 718 blocks the gap between the first connecting part 71 and the cosmetic assembly 3, and plays a role in improving the connection sealing between the cosmetic assembly 3 and the first connecting part 71.

[0366] In this scheme, the second connecting part 72 is located between the cosmetic instrument body 1 and the negative pressure sleeve 1a, and the opposite side surfaces of the second connecting part 72 are connected with the cosmetic instrument body 1 and the negative pressure sleeve 1a respectively. At this time, a laminated sealing structure is formed in the area of the second connecting part 72, the structure is more compact, and the overall sealing performance of the sealing ring 7 in the area of the second connecting part 72 can be further optimized.

[0367] Further, the end of the second connecting part 72 forms a hook section 725 which is folded towards one side, specifically, it can be folded towards the inside or outside of the second connecting part 72, in this scheme, the second connecting part 72 is folded towards the outside of the sealing ring 7, correspondingly, the end surface of the cosmetic instrument body 1 is provided with a hooking recess 1b1, the contour of the hooking recess 1b1 is shaped like the hook section 725, so as to provide the hooking recess 1b1 for the hook section 725 to be embedded in, at this time, under the cooperation of the hook section 725 and the hooking recess 1b1, the sealing ring 7 can be hooked at the cosmetic instrument body 1, and the connection between the sealing ring 7 and the cosmetic instrument body 1 is more compact.

[0368] Further, with reference to Figures 35 to 37 The negative pressure sleeve 1a is detachably arranged compared with the cosmetic instrument body 1, through this arrangement, in order to facilitate the installation of the sealing ring 7, in addition to this, in order to improve the installation stability of the second connecting part 72, the cosmetic instrument body 1 further comprises a shell 1b and an end cover 1c; wherein the hooking recess 1b1 is located at one end of the shell 1b, and the end cover 1c is fixedly arranged at one end of the shell 1b and covers the opening of the hooking recess 1b1, usually, the end cover 1c can be installed on the shell 1b by screw connection or buckle connection.

[0369] Meanwhile, the end cover 1c has a clamping protrusion 1c1 at the inner side position of the shell 1b. Generally, the clamping protrusion 1c1 is integrally connected with the end cover 1c. In this scheme, the clamping protrusion 1c1 is in a sheet structure and its size is smaller than the opening size of the clamping recess, so that the clamping protrusion 1c1 can be embedded in the hooking recess 1b1. At this time, the clamping protrusion 1c1 and the inner wall of the hooking recess 1b1 clamp and fix the barb section 725, the mounting stability of the second connecting portion 72 is improved, and it is not easy to loosen

[0370] In addition, because the negative pressure sleeve 1a is detachably arranged on the beauty instrument body 1, the gap between the adsorption sleeve 31b and the sealing ring 7 may be relatively large during the dismounting process, which may cause air leakage. Therefore, one side surface of the sealing ring 7 has a second sealing protruding ring 726, which abuts against the adsorption sleeve 31b. At this time, the second sealing protruding ring 726 arranged at the sealing ring 7 can block the gap between the adsorption sleeve 31b and the sealing ring 7, thereby further optimizing the air leakage problem.

[0371] It should be explained that in the above-mentioned two sealing implementation schemes of the negative pressure sleeve 1a and the beauty assembly 3, the first connecting portion 71 in different embodiments can be arranged alternately, and correspondingly, the second connecting portion 72 can also be arranged alternately. Regardless of the sealing structure of the first connecting portion 71 and the second connecting portion 72, the scheme that can realize the sealing effect of the negative pressure sleeve 1a and the beauty assembly 3 should be included in the equivalent interpretation range.

[0372] [Setting of air blowing structure]

[0373] Referring to Figure 38 In order to promote the absorption of essence, while adopting the above technical scheme, an air blowing structure can be arranged inside the beauty instrument. By applying the airflow to the skin, on the one hand, the discomfort caused by needle puncture, light and heating during the beauty process can be relieved, and on the other hand, a certain massage and promotion of essence flowing into pores can be achieved, so that the beauty experience is optimized.

[0374] It can be understood that the beauty instrument in the embodiment can also include a gas supply unit 14 and an airflow channel 15. The gas supply unit 14 and the airflow channel 15 are arranged on the beauty instrument body 1, respectively, 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. 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. The gas supply unit 14 sends the airflow acting on the skin outward through the airflow channel 15 and the air outlet 16, so as to improve the beauty experience. It can be understood that the beauty instrument in the embodiment can also include a gas supply unit 14 and an airflow channel 15. The gas supply unit 14 and the airflow channel 15 are arranged on the beauty instrument body 1, respectively, 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. 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. The gas supply unit 14 sends the airflow acting on the skin outward through the airflow channel 15 and the air outlet 16, so as to improve the beauty experience.

[0375] Further, the air flow channel 15 comprises a first air supply branch 154 arranged straight, one end of the first air supply branch 154 is connected with the air supply pump 142, and the other end is communicated with the air outlet 16, at this time, the straight first air 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.

[0376] The implementation principle of the embodiment is to provide a beauty instrument and a beauty kit for applying essence under negative pressure to solve the problem of poor control of the essence application area in the prior art.

[0377] Among them, the implementation modes 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, etc. can be combined arbitrarily under different needs without violating the laws of nature.

[0378] For example, in the present embodiment, the liquid storage cavity 6 has three implementation modes of being arranged in the beauty instrument body 1, being arranged in the main body piece 32, and being arranged in the container 61.

[0440] Further, in the present embodiment, the gas supply unit 14 can also play the effect of blowing air on the skin as in Embodiment One. However, in the setting, two gas supply schemes are mainly included. One is to use a single air pump to achieve the gas supply effect. In this scheme, a single air pump element can be used to realize the liquid output and air blowing functions. The other is to achieve the gas supply effect by using a double air pump. In this scheme, two different air pumps can be used to perform the liquid output and air blowing functions respectively.

[0441] Among them, referring to Figure 40 and Figure 44 In the single air pump scheme, based on the above components, for the convenience of description, the air flow channel 15 is divided into three parts, namely the first air flow channel 151, the second air flow channel 152 and the third air flow channel 153.

[0442] At this time, a beauty instrument can be obtained, which includes a beauty instrument body 1, one end of the beauty instrument body 1 is provided with a beauty head 31, further includes a gas supply unit 14 and a first air flow channel 151, the gas supply unit 14 is arranged in the interior of the beauty instrument body 1, one end of the beauty instrument body 1 is provided with a gas outlet 16 adjacent to the beauty head 31, the first air flow channel 151 is connected with the gas supply unit 14 and the gas outlet 16, the gas supply unit 14 sends out the air flow acting on the skin through the first air flow channel 151 and the gas outlet 16.

[0443] At this time, the gas supply unit 14 can generate air flow, press the air flow into the air flow channel 15, and the air flow is blown out from the gas outlet 16 and acts on the skin under the guidance of the air flow channel 15. At this time, the essence on the skin can be applied pressure to accelerate the penetration into the pores, the absorption effect of the essence is significantly improved, and the air blowing can accelerate the air flow on the skin surface and relieve the discomfort of the skin.

[0444] Further, the liquid outlet flow channel 1004 and the second air flow channel 152 are further included, the cosmetic head 31 is provided with 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 connection mode is the same as that of the liquid outlet air pump 141 and the air inlet flow channel 1005, and the connection mode is not repeated here; in addition, 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, and 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.

[0445] Under the above arrangement, the air supply unit 14 pressurizes the gas into the liquid storage cavity 6 through the second air flow channel 152, so that the essence liquid flows outwards through the liquid outlet flow channel 1004 and the liquid outlet 1002, thereby realizing the functions of liquid outlet and air blowing by using the same power source, and the functions of the cosmetic instrument are integrated.

[0446] It should be explained that under the condition of using 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 needs to be further arranged, therefore, in the single air pump scheme, the air supply unit 14 includes an air 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 air 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, and 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.

[0447] It should 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.

[0448] Further, in order to optimize the air flow effect, the cosmetic instrument further includes a switching valve 143, wherein the switching valve 143 has a multi-way 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 to the first air flow channel 151 or the second air flow channel 152 alone from the third air flow channel 153.

[0449] Under the action, the air flow can be controlled and adjusted, and by separately guiding the air flow to one of them, the air flow can have a good flow rate, and the function is more flexible and stable.

[0450] Further, at least one of the first airflow channel 151, the second airflow channel 152 and the third airflow channel 153 is a hose, preferably, in the embodiment, all of them are hose structures, which are convenient for wiring and layout, and can also bypass other components to avoid interference.

[0451] Further, when specifically arranged, if the first airflow channel 151, the second airflow channel 152 and the third airflow channel 153 have a bending part, it will cause kinetic energy loss when the gas is discharged, and the intensity of the gas discharge. At this time, in order to ensure the gas discharge effect, at least one of the first airflow channel 151, the second airflow channel 152 and the third airflow channel 153 is arranged in a straight shape. Under the arrangement of the above structure, the straight structure can reduce the collision loss lost in the gas flow process as much as possible, so that the gas flow can maintain a large flow rate. Preferably, in the embodiment, the first airflow channel 151 and the third airflow channel 153 are arranged in a straight shape.

[0452] Through the arrangement of the above structure, the first airflow channel 151 and the third airflow channel 153 form a first gas supply branch 154 for providing gas flow to the gas outlet 16, and the second airflow channel 152 and the third airflow channel 153 form a second gas supply branch 155 for providing gas flow to the liquid storage cavity 6.

[0453] Among them, in actual application, it is found that the gas flow intensity demand of the gas outlet 16 is large, otherwise the user's feeling when blowing will be weak. Based on this, preferably, the first gas supply branch 154 as a whole maintains a straight shape structure, and when arranged, only the first airflow channel 151 and the third airflow channel 153 need to be arranged coaxially. In this way, the gas flow loss in the first gas supply branch 154 can be avoided as much as possible.

[0454] But often in the beauty instrument body 1, due to space limitations, the first gas supply branch 154 will inevitably interfere with other components. In order to ensure that the gas outlet 16 has good gas discharge intensity, the first gas supply branch 154 can be provided with a avoiding bending part, and the proportion of the avoiding bending part to the total length of the first gas supply branch 154 is not more than 20%. In this way, the gas flow loss can be avoided as much as possible to ensure the blowing effect.

[0455] Correspondingly, if there is a situation of insufficient liquid discharge effect in different models of products, the position of the gas supply pump 142 can be adjusted to make the second gas supply branch 155 straight, and the avoiding bending part can be arranged on the second gas supply branch 155. Correspondingly, the proportion of the avoiding bending part to the total length of the first gas supply branch 154 is not more than 20% to ensure that the liquid discharge has sufficient gas flow intensity.

[0456] It can be understood that the setting position of the air outlet 16 is adjusted according to actual needs, such as being arranged on the beauty instrument body 1 and being arranged adjacent to the beauty head 31, or being directly arranged on the beauty head 31 to realize the blowing function while beautifying, and the scheme can be combined with the vibration mechanism 9 to be arranged synchronously, such as connecting the beauty head 31 with the vibration mechanism 9, and driving the beauty head 31 to reciprocate by the vibration mechanism 9 to realize the massage effect.

[0457] Referring to Figure 41 and Figure 45 In the double-gas-pump scheme, on the basis of the foregoing, the following scheme can be obtained: a beauty instrument, comprising a beauty instrument body 1, a beauty assembly 3, a gas supply unit 14 and an airflow channel 15, wherein the beauty assembly 3 is provided with an air inlet channel 1005, a liquid outlet channel 1004 and a liquid outlet 1002, one end of the liquid outlet channel 1004 is connected with the liquid outlet 1002, and the other end is used to be connected with the liquid storage cavity 6, and the beauty assembly 3 further comprises a microneedle wafer 3122 for piercing the skin.

[0459] Further, the beauty assembly 3 or the beauty instrument body 1 is provided with an air outlet 16, the airflow channel 15 communicates the gas supply unit 14 and the air outlet 16, and the gas supply unit 14 sends out the airflow acting on the skin through the airflow channel 15 and the air outlet 16.

[0460] The difference from the single-gas-pump scheme is that the gas supply unit 14 comprises a gas supply pump 142 and a liquid outlet pump 141, wherein the first airflow channel 151 independently forms a first gas supply branch 154, and the second airflow channel 152 independently forms a second gas supply branch 155, which can also be understood as that the airflow channel 15 comprises the first gas supply branch 154 and the second gas supply branch 155.

[0461] In the setting, one end of the first gas supply branch 154 is connected with the gas supply pump 142, and the other end is communicated with the air outlet 16, and one end of the second gas supply branch 155 is connected with the liquid outlet pump 141, and the other end is communicated with the air inlet channel 1005.

[0462] At this time, two independent gas paths are formed, and liquid outlet and blowing actions are performed respectively, and compared with the single-gas-pump scheme, the double-gas-pump scheme has greater single-path gas volume.

[0463] It needs to be explained that no matter whether the single air pump scheme or the double air pump scheme is set, the setting mode of the beauty component 3 can be consistent with the setting mode in embodiment one, and different combinations of the air supply unit 14 and the airflow channel 15 can be applied to the component combination in the foregoing, which will not be repeated here.

[0464] The implementation principle of embodiment two is that by adopting the liquid outflow mode of pressing in, the essence liquid in the container 61 can be fully flowed out, further reducing the residual essence liquid, and the skin care environment is more sanitary. Moreover, by changing the number of air pumps of the air supply unit 14, single pump air supply and double pump air supply schemes can be achieved, which can flexibly meet the design requirements of the structure, and the structure is flexible.

[0465] Moreover, based on the combined setting of embodiment two and embodiment one, various different types of beauty instrument schemes can be obtained.
