[0113] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0114] In the description of the present invention, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally disposed component to indirectly connect the two. When a component is considered to be "disposed on" another component, it may be directly disposed on the other component or there may be a centrally disposed component at the same time.

[0115] In addition, terms such as "long", "short", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0116] In conventional essence application beauty instrument products, the essence is usually applied by spraying. In this case, the essence will spread quickly before contacting the skin, resulting in the user being unable to control when they want to apply the essence accurately. For example, in the area around the eyes, the spraying method can easily cause the essence to enter the eyes and cause damage to the eyes, so further improvement is still needed.

[0117] The following is combined with Figure 1-45 The technical solution of the present invention is further illustrated by specific implementation methods.

[0118] Embodiment 1:

[0119] Please refer to Figures 1 to 38 , Figures 1 to 38 It is a structural schematic diagram and a cross-sectional view of a beauty instrument and related functional modules of the first embodiment of the present invention.

[0120] [About the beauty device with negative pressure adsorption and essence application function]

[0121] Please refer to Figures 1 to 3 An embodiment of the present invention provides a beauty instrument for skin care, which mainly includes 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.

[0122] Among them, the beauty instrument body 1 mainly provides an assembly position for various components, and the beauty head 31 is used to contact the skin and play a beauty role. In the specific setting, the negative pressure cavity 2 is first set at one end of the beauty instrument body 1. At the same time, a liquid storage cavity 6 for storing essence is also provided on the beauty instrument. The negative pressure cavity 2 is connected to the liquid storage cavity 6, so that the essence can flow into the negative pressure cavity 2 under the action of external force.

[0123] In addition, the beauty head 31 includes an adsorption element 3123 located in the negative pressure cavity 2. The adsorption element 3123 has a porous structure, and the porous structure can retain the essence that flows into the negative pressure cavity 2, so that the beauty head 31 can apply the essence to the skin. Specifically, in the porous structure of the adsorption element 3123, the outward opening can become the liquid outlet 1002 for applying the essence to the skin.

[0124] Furthermore, in this embodiment, the negative pressure mechanism 5 is arranged in the beauty instrument body 1, and the negative pressure mechanism 5 is connected to the negative pressure channel 4 and is used to suck gas in the negative pressure channel 4; specifically, the negative pressure channel 4 connects the liquid storage chamber 6, the negative pressure cavity 2 and the negative pressure mechanism 5 in sequence, and the negative pressure mechanism 5 forms a negative pressure area for sucking the skin in the negative pressure cavity 2 through the negative pressure channel 4, and causes the essence to be pumped from the liquid storage chamber 6 to the beauty head 31, and the essence is applied to the skin through the beauty head 31.

[0125] In the technical solution of the present invention, the skin area where the essence needs to be applied is adsorbed into the negative pressure area by negative pressure adsorption, thereby improving the control of the essence application area and reducing unnecessary damage caused by the diffusion of the essence.

[0126] In addition, the above scheme only needs to set up a negative pressure driving source, that is, a negative pressure mechanism 5. Under the action of the negative pressure channel 4, negative pressure can be formed in the liquid storage chamber 6 and the beauty head 31 at the same time, so as to achieve the effect of synchronous liquid discharge and negative suction of the skin; on the one hand, it can simplify the overall pipeline architecture, reduce the number of power sources required to perform the action, make the structure more compact, and achieve compactness of the beauty instrument; on the other hand, by setting the adsorption element 3123, it can be achieved that the extracted essence is retained at the adsorption element 3123, so that when the beauty head 31 contacts the skin, it can reduce the possibility of excessive backflow of the essence to the second half of the negative pressure channel 4 under negative pressure conditions, so that more essence can be applied to the skin, which greatly reduces the influence of the negative pressure environment on the overall flow direction of the essence, and the beauty effect is guaranteed, so that the negative pressure and liquid discharge functions can be achieved at the same time, and the technical difficulty of synchronously combining the negative suction function with the liquid discharge function is overcome.

[0127] [About negative pressure channel 4]

[0128] In this embodiment, the negative pressure channel 4 includes a first section and a second section, the first section is used to connect the liquid storage chamber 6 and the negative pressure chamber 2, and the second section is used to connect the negative pressure chamber 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 of the beauty instrument body 1 and the arrangement and stacking of parts; the negative pressure channel 4 can also be a tube-shaped passage integrally formed inside the beauty instrument body 1; in addition, the negative pressure channel 4 can also be a tube structure independent of the beauty instrument body 1. Optionally, the tube structure can be a hose structure.

[0129] It is understandable that the design of the tubular passage and the tube body structure can make the passage smoother and the fluid delivery more fluent; the design of the tubular passage has higher assembly efficiency, and the design of the tube body structure is easier to manufacture and assemble.

[0130] In one 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 32, which is hollow inside and has a shell-like structure. A first negative pressure pipeline 41 and a second negative pressure pipeline 42 are arranged inside the main body 32. The first negative pressure pipeline 41 mainly serves to discharge liquid, and the second negative pressure pipeline 42 serves to draw negative pressure.

[0131] Specifically, refer to Figure 3 and Figure 4 The first negative pressure pipe 41 can be installed inside the main body 32 and form the first section of the negative pressure channel 4. One end of the first negative pressure pipe 41 is connected to the beauty head 31 and communicated with the negative pressure cavity 2, and the other end is connected to the liquid storage cavity 6. The first negative pressure pipe 41 guides the essence to flow to the beauty head 31 to achieve the liquid discharge effect.

[0132] It is understandable that the main body 32 can be connected to a side outside the beauty instrument body 1, or the main body 32 can also be arranged inside the beauty instrument body 1. The main body 32 is located inside the beauty instrument body 1, which can make the structure more compact.

[0133] Furthermore, the second negative pressure pipe 42 can also be installed inside the main body 32 to form the second section of the negative pressure channel 4. One end of the second negative pressure pipe 42 is connected to the negative pressure cavity 2, and the other end is connected to the negative pressure mechanism 5.

[0134] At this time, by arranging the first negative pressure pipe 41 and the second negative pressure pipe 42 inside the hollow main body 32, the first negative pressure pipe 41 and the second negative pressure pipe 42 can construct and form a negative pressure channel 4, and the hollow main body 32 has a light structure and low manufacturing cost. At the same time, by arranging the first negative pressure pipe 41 and the second negative pressure pipe 42 inside it, the structural integration can form two independent flow circuits, wherein the first negative pressure pipe 41 is responsible for liquid outflow, and the second negative pressure pipe 42 is responsible for gas adsorption, and the two operate independently, are not easy to interfere, and are easy to produce and assemble, and have a compact structure.

[0135] Specifically, the first negative pressure pipe 41 and the second negative pressure pipe 42 can be tube-type passages integrally formed inside the main body 32, which are easy to assemble; or they can be independent tube structures arranged inside the main body 32, which are easy to produce and have low manufacturing costs. Furthermore, the first negative pressure pipe 41 can adopt a hose structure, which is conducive to structural assembly, and in the second negative pressure pipe 42, a hard pipe structure can be adopted, which can make the second negative pressure pipe 42 not easy to deform during the negative pressure extraction operation, keep the interior unobstructed, and better realize the negative suction function.

[0136] In one embodiment, in combination Figures 2 to 7 In order to improve the convenience of operation and the sanitary safety, the main body 32 and the beauty instrument body 1 are arranged to be detachably connected.

[0137] Specifically, refer to Figure 2 The beauty instrument body 1 has an installation opening 102 for disassembling and assembling the main body 32. In order to ensure the smooth assembly of the negative pressure channel 4 and the negative pressure mechanism 5 arranged in the main body 32, the beauty instrument body 1 has an installation opening 102 for disassembling and assembling the main body 32. Figure 6 and Figure 7 The beauty instrument is provided with a connecting portion 11 that can be assembled and connected to each other. The connecting portion 11 includes a first connecting portion 111 and a second connecting portion 112 to achieve the connection between the negative pressure channel 4 and the negative pressure mechanism 5.

[0138] Specifically, the first connecting portion 111 is disposed on the main body 32 and connected to the second negative pressure pipe 42 , and the second connecting portion 112 is connected to the negative pressure mechanism 5 . The specific configuration of the second connecting portion 112 will be described in detail in the subsequent description.

[0139] For further information, please refer to Figure 7 In order to ensure the airtightness of the connection between the negative pressure channel 4 and the negative pressure mechanism 5, an air intake seal ring 113 is provided at the connection between the first connecting portion 111 and the second connecting portion 112. Specifically, the first connecting portion 111 is inserted into the second connecting portion 112 to achieve the connection, and the air intake seal ring 113 is sleeved at the position where the first connecting portion 111 is inserted into the second connecting portion 112.

[0140] Further, refer to Figure 3 In order to control the essence to flow slowly and evenly to the outside, a slow flow design can be added. In one embodiment, a slow flow member 43 can be provided in the negative pressure channel 4. The slow flow member 43 has a porous structure. Specifically, sponge, cotton, porous silica gel or porous ceramic and other materials can be used. Any structure that can achieve a slow flow effect can be tried. No specific restrictions are made here. The slow flow member 43 is provided between the liquid storage chamber 6 and the beauty head 31. The loose porous structure can slow down the flow rate of the essence. In this case, the essence can be evenly and slowly transported to the beauty head 31 to achieve a stable liquid discharge effect.

[0141] The provision of the slow-flow component 43 also facilitates later use and maintenance. For example, when the negative pressure channel 4 is clogged, the blockage problem can be solved by replacing the slow-flow component 43, which is simple and quick. 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 chamber 6 and the beauty head 31 is set 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 chamber 6 and the beauty head 31 is designed as a hose, a slot is set at any point outside the section of the hose, and the hose is set in the slot. The inner diameter of the section of the hose passing through the slot will be reduced. The inner diameter size of the negative pressure channel 4 is limited by structural design, and the structural design is simple, which can reduce manufacturing costs.

[0142] [About negative pressure mechanism 5]

[0143] Please refer to Figure 2 In this embodiment, the negative pressure mechanism 5 includes a negative pressure pump 51, which is fixedly installed inside the beauty instrument body 1, and the suction end of the negative pressure pump 51 is connected to the second section of the negative pressure channel 4 for extracting air from the negative pressure channel 4.

[0144] In one embodiment, the negative pressure mechanism 5 also includes a solenoid valve 52, which is also connected to the negative pressure channel 4 and is used to replenish gas into the negative pressure channel 4 to break the negative pressure state in the negative pressure cavity 2, so that the user can smoothly move the beauty instrument away from the skin without causing damage to the skin.

[0145] Furthermore, in order to realize the automatic control of the negative pressure pump 51 and the electromagnetic valve 52, the beauty instrument also includes a main control circuit board 17, on which a control element is arranged, and the negative pressure mechanism 5 also includes an air pressure sensor 53 arranged on the main control circuit board 17, wherein the receiving end of the air pressure sensor 53 is connected to the negative pressure channel 4, and the air pressure sensor 53 can detect the negative pressure condition in the negative pressure channel 4, and then can obtain the negative pressure condition of the negative pressure cavity 2, and synchronously generate a negative pressure signal. Furthermore, the control element is respectively connected to the air pressure sensor 53, the negative pressure pump 51 and the electromagnetic valve 52, and the control element can adopt a control chip, and any element that can realize the control function can be used, and no specific limitation is made here.

[0146] Based on this, after the air pressure sensor 53 obtains the negative pressure signal according to the air pressure conditions in the negative pressure channel 4, the negative pressure signal is sent to the receiving end of the control element. The control element analyzes the negative pressure signal and forms a control signal. Then the control element sends the control signal to the negative pressure pump 51 and the solenoid valve 52 accordingly to control the start and stop of the negative pressure pump 51 and the solenoid valve 52, thereby realizing automatic control and optimizing and improving the user experience.

[0147] Furthermore, in order to optimize the compactness of the internal pipeline, the beauty instrument also includes a multi-way valve 54, which includes at least four interconnected interfaces. The number of interfaces is related to the number of components that the negative pressure channel 4 needs to be connected to. In the present embodiment, four interfaces are selected, i.e., a four-way valve structure. The number of interfaces is not specifically limited. Based on this, the air pressure sensor 53, the negative pressure pump 51, the solenoid valve 52 and the negative pressure channel 4 are correspondingly connected to several interfaces of the multi-way valve 54. Here, the multi-way valve 54 can integrate the air pressure sensor 53, the negative pressure channel 4, the solenoid valve 52 and the negative pressure pump 51 together through several interfaces, so that the internal pipeline is more concise and compact.

[0148] [About liquid storage chamber 6]

[0149] In this embodiment, the liquid storage chamber 6 can be formed in the beauty device body; or, when the beauty device is provided with a main body 32, it is formed in the main body 32; or, the liquid storage chamber 6 can be a storage space of a container 61. The above specific implementations are described below.

[0150] Please refer to Figure 8In the embodiment where the liquid storage chamber 6 is formed in the main body 32, the beauty instrument can be considered as a beauty instrument including the liquid storage chamber 6. Specifically, a partition 62 is provided in the main body 32, and an independent space is separated by the partition 62. The space can constitute the liquid storage chamber 6 for storing the essence. At the same time, a supplementary port 63 is provided in the main body 32, and the essence can be supplemented through the supplementary port 63. Through this setting, while ensuring the basic function of delivering the essence, it can also support users to inject different essences according to their needs to meet the different needs of users.

[0151] It is understandable that when the main body 32 is configured to be non-detachably connected to the beauty instrument body 1, the main body 32 has an addition port 63 for replenishing the essence, and the user can replenish the essence into the liquid storage chamber 6 through the addition port 63. Correspondingly, when the main body 32 is fixedly arranged in the beauty instrument body 1, the beauty instrument body 1 also needs to be provided with a corresponding opening at the position corresponding to the addition port 63 of the main body 32, so as to achieve the replenishment of the essence.

[0152] This arrangement can achieve a highly integrated effect, and the main body 32 can well store the essence and accommodate the negative pressure channel 4 .

[0153] In order to further improve the convenience of operation, the main body 32 can be set to be detachably connected to the beauty instrument body 1. It is understandable that in this case, the beauty instrument body 1 may no longer be provided with an opening corresponding to the addition port 63 on the main body 32. Through this setting, the design of the beauty instrument body 1 can be simplified, and the convenience of the user to replenish the essence can be improved.

[0154] In addition, the main body 32 may not be provided with the addition port 63. In this case, the main body 32 is provided as a consumable. When the essence 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. This design further improves convenience, hygiene and safety, and user experience.

[0155] However, although the method of directly integrating the liquid storage chamber 6 into the main body 32 has a compact structure, it is not conducive to the user to observe the remaining amount of liquid. In order to further optimize the user experience, a transparent window can be set on the main body 32 and / or the beauty instrument body 1, through which the remaining amount of essence can be observed.

[0156] Specifically, when the main body 32 is connected to one end of the beauty instrument body 1 and is located outside the beauty instrument body 1, it is only necessary to set a transparent window on the main body 32; and when the main body 32 is set inside the beauty instrument body 1, it is not only necessary to set a transparent window on the main body 32, but also to set a transparent window on the beauty instrument body 1 at a position 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 a transparent window.

[0157] In the embodiment where the liquid storage chamber 6 is formed in the beauty instrument body 1, the beauty instrument can also be considered as a beauty instrument including the liquid storage chamber 6, and can also be understood as directly setting the liquid storage chamber 6 on the beauty instrument body 1, and the specific implementation method of the liquid storage chamber 6 is the same as the method of forming the liquid storage chamber 6 in the main body 32. It can be understood that at this time, the beauty instrument body 1 can be provided with an addition port 63 according to the need to replenish the essence, and a transparent window can be provided according to the need to observe the remaining amount of the essence, and other specific settings are not repeated here.

[0158] Please refer to Fig. 9 In the manner of setting the storage space of the container 61 as the liquid storage chamber 6, the container 61 is located outside the beauty instrument body 1 and connected to the beauty instrument body 1. The container 61 can be a container 61 of a vial structure, a soft bag structure, etc. that can store essence. In this embodiment, a vial structure with a higher hygienic standard is selected. At this time, the internal storage space of the container 61 forms the liquid storage chamber 6, which further optimizes the convenience of observing the remaining amount of the essence.

[0159] In this embodiment, reference Fig.10 The beauty instrument and the container 61 constitute a beauty kit. When the container 61 is assembled on the beauty instrument body 1, the container 61 is connected to the negative pressure mechanism 5 through the negative pressure channel 4 at the same time, thereby realizing the supply and delivery of the essence. The settings of the negative pressure channel 4 and the negative pressure mechanism 5 are as described above and will not be repeated here.

[0160] In this embodiment, reference Fig. 9 and Fig.10 In order to realize the mutual assembly of the beauty kit, the beauty instrument is provided with a connecting portion 33. After the container 61 is assembled with the beauty instrument through the connecting portion 33, the beauty instrument can be connected with the container 61, and then the essence is taken out from the container 61 and delivered to the human skin, thereby realizing skin care.

[0161] Please refer to Fig.10 Specifically, the beauty instrument is provided with a bottle mouth slot 339 for inserting the container 61 , and a plug-in portion 330 is convexly provided at the bottom of the bottle mouth slot 339 , and the connecting portion 33 includes the aforementioned bottle mouth slot 339 and the plug-in portion 330 .

[0162] At this time, when the container 61 is inserted into the bottle mouth slot 339, on the one hand, the bottle mouth slot 339 can clamp the container 61 to prevent the container 61 from being separated from the beauty instrument; on the other hand, the connecting part 33 will be inserted into the container 61 so as to take the essence from the container 61.

[0163] Specifically, to achieve the above purpose, when a new container 61 needs to be replaced, the head of the container 61 is inserted downward into the bottle mouth slot 339. Due to the clamping effect of the bottle mouth slot 339, the container 61 will not be separated from the bottle mouth slot 339 of the main body 32; when the head of the container 61 is inserted downward into the bottle mouth slot 339; synchronously, the connecting part 33 is inserted upward into the container 61 to take the essence or other functional liquid (such as cleaning liquid for cleaning the liquid outlet channel, etc.) from the container 61; when the essence or other functional liquid in the container 61 is used up, the container 61 can be directly pulled out upward.

[0164] During the assembly and disassembly of the container 61, there is no need to perform cumbersome twisting operations, only simple plugging and unplugging operations are required, and the operation is very convenient. Therefore, this setting can effectively solve the problem that the assembly and disassembly of the existing beauty instrument kit assembled by threads requires twisting operations and is less convenient.

[0165] For further information, please refer to Figure 5 and Fig. 9 In order to smoothly deliver the essence in the container 61 to the beauty head 31, the plug-in portion 330 is respectively provided with an outflow port 331 and an air inlet 332. One end of the first section in the negative pressure channel 4 is fixedly connected to the plug-in portion 330 and communicated with the outflow port 331, while the air inlet 332 is exposed to the outside to connect the container 61 with the outside. It can be understood that due to the tension of the essence itself, when the plug-in portion 330 is connected to the container 61, the essence itself is not easy to flow out from the air inlet 332.

[0166] Through the above-mentioned arrangement, the outflow port 331 and the air inlet 332 are integrated on the plug-in portion 330, so that when the plug-in portion 330 is inserted into the container 61, the interior of the container 61 can be connected to the outside world and the negative pressure channel 4 at the same time. While negative pressure is formed inside the negative pressure channel 4, the atmospheric pressure balance inside and outside the container 61 is maintained through the air inlet 332, making the liquid discharge smoother.

[0167] For further information, please refer again to Figure 5 and Fig.10In this embodiment, a plurality of outwardly protruding groove wall bosses 338 are provided at the groove wall position of the bottle mouth slot 339; the groove wall bosses 338 are used to limit the container 61 from being separated from the bottle mouth slot 339. Accordingly, the container 61 includes a bottle body 611 for storing essence, a bottle mouth 612 for inserting into the bottle mouth slot 339, and a bottleneck 613 connecting the bottle body 611 and the bottle mouth 612. The outer edge of the bottle mouth 612 protrudes from the bottleneck 613, so that the outer edge of the bottle mouth 612 is engaged with each groove wall boss 338 of the beauty instrument.

[0168] The groove wall of the bottle slot 339 in this embodiment is provided with groove wall bosses 338 protruding outward, which can effectively clamp the edge of the container 61 to prevent the container 61 from accidentally falling off after being inserted into the bottle slot 339. That is, when the container 61 is inserted into the slot, the outer edge of the bottle mouth 612 and the groove wall bosses 338 form a tight fit, ensuring the stability of the container 61 in the beauty instrument, so that the user does not need to worry about the looseness of the container 61 when performing skin care, thereby improving the safety of use and the stability of liquid supply.

[0169] Optional, such as Fig.10 As shown, the container 61 further includes a sealing plug 614 for sealing the bottle mouth 612, and an aluminum film 615 covering the sealing plug 614 and the bottle mouth 612. The sealing plug 614 is provided with a plug hole 6141 for the plug-in portion 330 to be inserted, and a fragile film 6142 for covering the plug hole 6141, and the aluminum film 615 is provided with a film avoidance hole corresponding to the plug hole 6141 for the connection portion 33 to pass through.

[0170] When the plug part 330 is not inserted into the plug hole 6141, the fragile film 6142 can seal the plug hole 6141, which can prevent the liquid inside the container 61 from being polluted by the environment, ensure safety and hygiene, and at the same time, prevent the essence 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 plug part 330 is inserted into the plug hole 6141, and the fragile film 6142 will be pierced by the plug part 330, so as to achieve the outflow of the essence. This design not only ensures the sealing of the container 61, but also is easy to use. The aluminum film 615 is mainly used to limit the sealing plug 614 and the bottle mouth 612, so as to prevent the sealing plug 614 from being flushed out of the bottle mouth 612 under the action of air pressure when the pressure inside the container 61 is high.

[0171] Furthermore, in this embodiment, the plug part 330 is configured to be columnar or conical. The opening of the container 61 or the plug part 330 may be provided with an elastic structural member, such as flexible rubber, so that the plug part 330 and the container 61 form an interference fit to prevent the essence from leaking from the connection between the two.

[0172] Optional, see Fig.10 and Fig.11The plug-in portion 330 includes a top surface of a conical surface structure 334 and a circumferential side surface of 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 to seal the gap between the plug-in portion 330 and the container 61.

[0173] When the container 61 is inserted into the bottle mouth slot 339, the conical surface structure 334 punctures the fragile membrane, and the cylindrical surface structure 335 forms an interference fit with the inner wall of the plug hole 6141, ensuring the sealing and stability of the essence during the transmission process. The top surface of the conical surface structure 334 is conducive to the plug part 330 to easily puncture the fragile membrane 6142, saving the effort required to puncture the fragile membrane 6142. The circumferential side surface of the cylindrical surface structure 335 can increase the contact area between the hole wall of the plug hole 6141 and the plug part 330, so as to improve the sealing performance between the plug part 330 and the sealing plug 614.

[0174] It can be understood that the plug-in angle of the syringe bottle can be set to multiple angles. At this time, the plane where the liquid outlet 1002 is located is used as a reference, and the length direction of the beauty instrument is also perpendicular to the plane. At this time, the angle formed by the extension direction of the plug-in portion 330 and the plane where the liquid outlet 1002 is located is between 0 degrees and 90 degrees. At this time, a plug-in angle of the syringe bottle that is 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 plug-in assembly of the syringe bottle can be achieved. According to actual needs, the shape of the beauty instrument body 1 and the structural angle of the plug-in portion 330 can be adjusted to meet the above-mentioned plug-in effect. No specific limitation is made here. In this embodiment, the angle is selected as 0 degree for example.

[0175] In summary, the related arrangement of the connection portion 33 and the container 61 has the following advantages:

[0176] ① The beauty instrument is provided with a bottle mouth slot 339 for inserting the container 61. When the container 61 is subsequently assembled and disassembled, there is no need to perform cumbersome twisting operations, but only simple plugging and unplugging operations, which is convenient to operate;

[0177] ② The conical surface structure 334 and the cylindrical surface structure 335 of the connecting portion 33 ensure an interference fit with the plug hole 6141 of the container 61, achieving a good seal during the transmission of the essence and avoiding leakage problems;

[0178] ③ The design of the sealing plug 614 and the fragile film 6142 of the container 61 enables the container 61 to remain sealed during storage and transportation, thereby ensuring the quality and activity of the essence.

[0179] It is understandable that there are many other connection part 33 structures that can achieve plug-in connection. This embodiment provides another connection part 33, which is suitable for the beauty instrument and beauty kit in the aforementioned embodiment, and can also achieve the gas supply and liquid delivery functions.

[0180] Based on the arrangement of the aforementioned connecting portion 11, unexplained features are explained using the aforementioned embodiment and will not be described in detail here.

[0181] Reference Fig.12 The difference between the configuration of the connecting portion 33 and the aforementioned embodiment is that:

[0182] The connecting portion 33 includes an air inlet needle tube 336 for supplying air to the container 61 , and a liquid outlet needle tube 337 for supplying liquid out of the container 61 .

[0183] Correspondingly, the sealing plug 614 is provided with an air inlet needle hole 6143 for inserting the air inlet needle tube 336 , an air inlet film for covering the air inlet needle hole 6143 , a liquid outlet needle hole 6144 for inserting the liquid outlet needle tube 337 , and a liquid outlet film for covering the liquid outlet needle hole 6144 .

[0184] When inserting the container 61 into the bottle mouth slot 339, first align the air inlet needle tube 336 with the air inlet film, and align the liquid outlet needle tube 337 with the liquid outlet film; 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 and the air inlet needle hole 6143 are interference fit to seal the air inlet needle hole 6143, and the liquid outlet needle tube 337 and the liquid outlet needle hole 6144 are interference fit to seal the liquid outlet needle hole 6144.

[0185] The connection part 33 provided in the above embodiment 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. As for how to take the essence liquid out of the container 61 through the pressure difference, it will not be repeated here.

[0186] It can be understood from the above-mentioned setting of the beauty instrument that in the manner of setting the accommodation space of the container 61 as the liquid storage chamber 6, there are two situations in which the setting object of the connection part 33 exists due to the setting of the beauty instrument: first, when the beauty instrument is not provided with the main body 32, the connection part 33 is provided 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; second, when the beauty instrument is provided with the main body 32, the connection part 33 is provided 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 methods of the connection part 33 are specifically described below.

[0187] In the case where the connecting portion 33 is arranged on the beauty instrument body 1, the beauty instrument body 1 is detachably connected to the container 61 through the connecting portion 33, and the container 61 is connected to the negative pressure channel 4 through the connecting portion 33. The specific structural setting of the connecting portion 33 is the same as the aforementioned structural setting method, and will not be repeated here.

[0188] In the case where the connection portion 33 is provided on the main body member 32, as Fig.10 As shown, except for the different location of the connection part 33, the other structural settings are the same as the setting mode of the connection part 33 described above, and will not be repeated here. In the setting mode of this embodiment, the connection part 33 is set on the main body 32, rather than being set on the beauty instrument body 1 as described above. Specifically, the connection part 33 is connected to the main body 32 or is integrally formed with the main body 32. In addition, the main body 32 is also provided with the above-mentioned negative pressure channel 4. When the container 61 is connected to the main body 32 through the connection part 33, the container 61 is connected to the negative pressure channel 4 to achieve the liquid discharge function.

[0189] Further, refer to Fig.13 , a positioning recess 333 is provided on the main body 32, and the positioning recess 333 is the above-mentioned bottle mouth slot 339. The positioning recess 333 has a bottom wall and a side wall connected to the bottom wall, and the plug-in portion 330 is provided on the bottom wall, and the side wall is provided with a limiting portion. It should be explained that the limiting portion is the above-mentioned groove wall boss 338. Of course, the above-mentioned groove wall boss 338 structure can also be replaced by other limiting methods described below. In some embodiments, the limiting portion is a surface that can be set as a side wall, and the extended contour of the entire side wall is adapted to the outer peripheral contour of the container 61. At this time, the limiting portion can be abutted against the peripheral side of the container 61 when the container 61 is connected to the plug-in portion, which plays the effect of assembling and positioning the container 61, so that the container 61 can be plugged and unplugged with the connecting portion 33 more quickly and accurately, and the user experience is further optimized and improved.

[0190] It should be noted that the limiting part can also be a sliding limiting structure such as a slider and a slide rail. Any structure that can achieve guidance when the container 61 and the connecting part 33 are plugged in and out can be tried and is not specifically limited here.

[0191] It can be understood that in the embodiment in which the connecting portion 33 is disposed on the main body 32, when the main body 32 is disposed inside the beauty instrument body 1, Fig.13 Here, when the main body 32 is set in the beauty instrument body, a first avoidance opening 101 is opened on one side of the beauty instrument body 1. The first avoidance opening 101 runs through the inner and outer sides of the beauty instrument body 1. The setting position of the first avoidance opening 101 corresponds to the connecting portion 33 on the main body 32. The first avoidance opening 101 can expose the connecting portion 33 for the container 61 to be disassembled and assembled.

[0192] By installing the container 61 into the connecting portion 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 and assemble 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, allowing customers to selectively replace the container 61 regularly, reducing the problem of bacterial growth caused by long-term residual essence, and making the skin care environment cleaner and more hygienic.

[0193] [About the beauty instrument 1]

[0194] In this embodiment, the liquid storage chamber 6 has a variety of different configurations. Corresponding to each configuration of the liquid storage chamber 6 , the beauty instrument body 1 is correspondingly provided with a structural configuration for adding essence or replacing the essence container 61 .

[0195] Specifically, in a configuration in which a liquid storage chamber 6 is provided inside the beauty instrument body 1, an opening for replenishing and adding essence is correspondingly provided on the beauty instrument body 1; in a configuration in which a container 61 is provided outside the beauty instrument body 1, a first avoidance opening 101 for disassembling and assembling the container 61 is correspondingly provided on the beauty instrument body 1.

[0196] Due to the above arrangement, foreign matter such as dust from the outside can easily enter the liquid storage chamber 6 from the opening or the first avoidance opening 101, contaminating the essence added later. In order to improve the sanitation and safety of the beauty care environment, the beauty instrument further includes a sliding cover 13 for shielding the above opening or the first avoidance opening 101. The following is a specific description using the setting of the sliding cover 13 shielding the first avoidance opening 101 as an example. The setting of the sliding cover 13 shielding the opening is the same as the following description and will not be repeated.

[0197] refer to Fig.15 The surface of the beauty instrument body 1 is also provided with a first avoidance opening 101 for exposing the connection portion 33. The beauty instrument further includes a sliding cover 13, which is slidably connected to the beauty instrument body 1. The sliding cover 13 has a closed state in which it slides relative to the beauty instrument body 1 to cover the beauty instrument body, and an open state in which it slides relative to the beauty instrument body 1 to open the first avoidance opening 101.

[0198] When the container 61 needs to be loaded, the sliding cover 13 is slid to the open state, so that the first escape opening 101 is exposed, and then the container 61 can be inserted into the first escape opening 101; when the container 61 is taken out, the sliding cover 13 is slid to the closed state, so that the first escape opening 101 is covered, thereby preventing dust and other foreign objects from entering the first escape opening 101. The setting of the sliding cover 13 can effectively solve the problem that foreign objects such as dust from the outside can easily enter the beauty instrument through the installation position of the container 61, thereby ensuring the sanitation and safety of the beauty care environment.

[0199] Specifically, see Figures 15 to 19The 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.

[0200] The cooperation between the guide groove 103 and the guide protrusion 131 realizes the precise sliding connection between the slide cover 13 and the beauty instrument body 1. When the slide cover 13 slides along the guide groove 103, the guide protrusion 131 is inserted into the guide groove 103, which ensures the stability of the slide cover 13 during the sliding process and avoids skewing or jumping.

[0201] See also Fig.16 as well as Fig.17 The beauty instrument body 1 is provided with a positioning groove 104 extending along the sliding direction of the sliding cover 13. A positioning protrusion 132 is provided on the surface of the sliding cover 13 close to the beauty instrument body 1; wherein the positioning protrusion 132 is inserted into the positioning groove 104 and slides along the positioning groove 104.

[0202] The groove wall of the positioning groove 104 is provided with a switch positioning block 105 which is slidably abutted against the positioning protrusion 132: when the sliding cover 13 is in a closed state, the switch positioning block 105 is located on the side of the positioning protrusion 132 away from the first avoidance opening 101, which can prevent the sliding cover 13 from sliding in the direction away from the first avoidance opening 101, thereby maintaining the closed state of the sliding cover 13; when the sliding cover 13 is in an open state, the switch positioning block 105 is located on the side of the positioning protrusion 132 close to the first avoidance opening 101, which can prevent the sliding cover 13 from sliding in the direction close to the first avoidance opening 101, thereby maintaining the open state of the sliding cover 13.

[0203] Continue to refer to Fig.18 and Fig.19 The switch positioning block 105 is mainly used to maintain the stability of the open cover state and the closed cover state. When the state of the sliding cover 13 needs to be switched, a certain thrust needs to be applied to push the sliding cover 13 to overcome the abutment between the switch positioning block 105 and the positioning protrusion 132, so that the sliding cover 13 slides over the switch positioning block 105.

[0204] Optionally, the number of the positioning grooves 104 and the positioning protrusions 132 are both set to two, and the two positioning grooves 104 are symmetrically arranged about the guide groove 103. Providing two positioning grooves 104 symmetrical to the guide groove 103 further improves the connection stability between the sliding cover 13 and the beauty instrument body 1. The design of the two positioning grooves 104 makes the sliding cover 13 more stable during the sliding process, and further avoids the sliding cover 13 from tilting or jumping during the sliding process.

[0205] In this embodiment, the positioning groove 104 is a through groove. The positioning protrusion 132 is connected to a hooking portion 133 located in the beauty instrument body 1; the width of the hooking portion 133 is larger than the width of the positioning groove 104 to limit the hooking portion 133 from escaping from the beauty instrument body 1 through the positioning groove 104.

[0206] Furthermore, the beauty instrument body 1 is provided with a disassembly groove 107 connected to one end of the positioning groove 104 close to the first avoidance opening 101; the width of the disassembly groove 107 is greater than the width of the hook and lock portion 133, so that the hook and lock portion 133 enters and exits the beauty instrument body 1 through the disassembly groove 107.

[0207] The width of the hooking portion 133 is greater than the width of the positioning slot 104 , so that the hooking portion 133 will not fall off easily when sliding in the positioning slot 104 , thereby improving the connection stability between the sliding cover 13 and the beauty instrument body 1 .

[0208] When the sliding cover 13 needs to be removed, the hook lock portion 133 needs to be slid to the bottom of the disassembly slot 107 first, and then the sliding cover 13 is lifted upward. During the upward movement of the sliding cover 13, the hook lock portion 133 passes through the disassembly slot 107, thereby separating from the beauty instrument body 1. Similarly, when the sliding cover 13 needs to be installed, the hook lock portion 133 should also be passed downward through the disassembly slot 107, and then the sliding cover 13 should be pushed horizontally so that the positioning protrusion 132 enters the positioning slot 104.

[0209] Optional, see Fig.19 The groove wall of the positioning groove 104 is also provided with a disassembly positioning block 106 ; when the positioning protrusion 132 abuts against the disassembly positioning block 106 on the surface facing the first avoidance opening 101 , the positioning protrusion 132 is partially or completely located in the positioning groove 104 .

[0210] It is understandable that, generally, when the user performs the cover opening and closing operation, the positioning protrusion 132 slides on the side of the disassembly and assembly positioning block 106 away from the first avoidance opening 101, that is, the positioning protrusion 132 is always at least partially located in the positioning groove 104, so that the user can avoid accidentally lifting the sliding cover 13 upward, causing the sliding cover 13 to separate from the beauty instrument body 1. That is, when the user pushes the sliding cover 13 in the direction close to the first avoidance opening 101, the sliding cover 13 will first abut against the disassembly and assembly positioning block 106, at which time the user can feel obvious resistance, thereby knowing that the limit position of the cover closing state has been reached, and it is no longer necessary to continue to push the sliding cover 13 with force.

[0211] If the user does not only want to close the cover, but also want to remove the sliding cover 13, then the user can continue to push the sliding cover 13 with force, so that the positioning protrusion 132 passes over the disassembly positioning block 106. At this time, the positioning protrusion 132 completely leaves the positioning groove 104 with a smaller width dimension, and completely enters the disassembly groove 107 with a larger width dimension, and the sliding cover 13 can be lifted up to remove the sliding cover 13. That is, the disassembly positioning block 106 can play a certain fool-proof role, effectively preventing the user from accidentally removing the sliding cover 13 when closing the cover.

[0212] Optionally, the switch positioning block 105 and the disassembly positioning block 106 are located on the same groove wall of the positioning groove 104, and the disassembly positioning block 106 is located on the side of the positioning protrusion 132 close to the first avoidance opening 101. The positioning protrusion 132 is provided with an abutment boss 1321 for slidingly abutting the switch positioning block 105 and the disassembly positioning block 106. The switch positioning block 105 and / or the disassembly positioning block 106 are provided with an elastic groove 108 on the side away from the abutment boss 1321. It can be understood that the switch positioning block 105 and the disassembly positioning block 106 can of course also be located on different groove walls of the positioning groove 104, and the elastic groove 108 is provided adjacent to the disassembly positioning block 106.

[0213] The abutment boss 1321 protrudes toward the switch positioning block 105 and the disassembly positioning block 106. When the user pushes the sliding cover 13 to make the abutment boss 1321 pass over the switch positioning block 105 or the disassembly positioning block 106, the switch positioning block 105 and the disassembly positioning block 106 are supported by the abutment boss 1321 and will undergo a certain displacement deformation toward the corresponding elastic groove 108, thereby providing the user with a damping feel and a "click" sound. The user can judge whether the positioning block 132 has successfully passed over the switch positioning block 105 or the disassembly positioning block 106 by the damping feel and sound.

[0214] In summary, the beauty instrument and beauty kit provided by this embodiment have the following advantages:

[0215] ① By 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 avoidance opening 101 and the connecting portion 33) can be completely covered after the container 61 is pulled out, effectively preventing foreign matter such as dust from entering the interior of the beauty instrument, and keeping the beauty instrument clean and hygienic;

[0216] ② The design of the switch positioning block 105 ensures that the sliding cover 13 can remain stable in both the open and closed states, and will not slide accidentally due to external forces, thus ensuring the normal use of the beauty instrument;

[0217] ③ The design of the hook lock portion 133, the disassembly slot 107, and the disassembly positioning block 106 can not only provide the disassembly function of the sliding cover 13, but also have a certain fool-proof effect, thereby preventing the user from accidentally disassembling the sliding cover 13 when closing the cover, thereby improving the reliability of use;

[0218] ④ The design of the elastic groove 108 and the abutting boss 1321 provides an obvious click feeling and sound feedback, allowing the user to clearly perceive the state change of the sliding cover 13, thereby improving the user experience.

[0219] In this embodiment, when the main body 32 is detachably mounted in the beauty instrument body 1 and the container 61 is detachably connected to the main body 32, the problem of being unable to clean or replace the essence delivery component can be solved. The following is a specific description of the disassembly and assembly structure of the main body 32 and the container 61.

[0220] In one embodiment, please refer to Figure 2 , Figure 3 , Fig.10 as well as Fig.18 The installation opening 102 is located at the end surface of the beauty instrument body 1, and the first avoidance opening 101 is located at the circumferential surface of the beauty instrument body 1. The installation opening 102 and the first avoidance opening 101 are connected to each other through the internal space of the beauty instrument body 1. The main body 32 is connected to the beauty instrument body 1 through the installation opening 102, and the container 1 is connected to the main body 3 through the first avoidance opening 201, so as to communicate with the liquid outlet channel 1004 (i.e., the first negative pressure pipeline 41) inside the main body 3.

[0221] Please continue to refer to Figure 2 and Fig.10 In the beauty instrument and beauty kit provided in this embodiment, the beauty head 31 is connected to one end of the main body 32 and exposed to the beauty instrument body 1. When it is necessary to disassemble and clean the parts with liquid residue, the container 61 can be pulled out of the first avoidance port 101 in the longitudinal direction and upward, and then the main body 32 and the beauty head 31 can be pulled out of the installation port 102 in the transverse direction to the right. At this time, the main body 32, the beauty head 31, and the liquid outlet channel 1004 can be disassembled and cleaned or replaced. After cleaning is completed or new parts are taken, the main body 32 and the beauty head 31 are first inserted into the beauty instrument body 1 through the installation port 102 in the transverse direction to the left, and then the container 61 is inserted into the main body 32 in the longitudinal direction through the first avoidance port 101 downward, and the assembly operation can be completed. Therefore, the beauty instrument provided in this embodiment can effectively solve the problem that the existing beauty instrument cannot clean or replace the essence delivery parts.

[0222] In this implementation mode, please combine Figure 2 and Figure 5The main body 32 includes 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; wherein, the liquid outlet channel 1004 is located in the main body inner cavity 32a1. Furthermore, the size of the opening of the main body inner cavity 32a1 is larger than the size of the liquid outlet channel 1004, so that the liquid outlet 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 to cover the opening of the main body inner cavity 32a1. Optionally, the main body bottom box 32a and the main body top cover 32b are magnetically connected and / or snap-connected, so that the user can easily open the main body top cover 32b without using tools such as screwdrivers, and take out the liquid outlet channel 1004 through the opening of the main body inner cavity 32a1 and clean it.

[0223] Optionally, the liquid outlet channel 1004 is a hose with a changeable shape for easy assembly and disassembly.

[0224] Please refer to Figure 6 and Figure 7 The end of the main body top cover 32b away from the beauty head 31 is provided with a first connecting portion 111 for connecting to the air inlet 332 through the air inlet channel 1005 (i.e., the second negative pressure pipe 42). Accordingly, the interior of the beauty instrument body 1 is provided with a second connecting portion 112 for conveying gas to the first connecting portion 111 and plugging and unplugging with the first connecting portion 111 at a position corresponding to the first connecting portion 111. Furthermore, an air inlet sealing ring 113 is sleeved at the position where the first connecting portion 111 is inserted into the second connecting portion 112.

[0225] In summary, the beauty instrument and beauty kit provided in this embodiment have the following advantages:

[0226] ① By providing the first avoidance opening 101 and the installation opening 102 on the beauty instrument body 1, the main body 32, the beauty head 31 and the liquid outlet channel 1004 can be disassembled relative to the beauty instrument body 1, so as to clean and replace the essence delivery components such as the main body 32, the beauty head 31 and the liquid outlet channel 1004;

[0227] ② The main body bottom box 32a and the main body top cover 32b are detachable structures connected by snaps or magnetic attraction, so that the user can easily open the main body bottom box 32a, take out the liquid outlet channel 1004 for maintenance and cleaning, which enhances the maintainability of the device;

[0228] ③ By providing the first connecting portion 111, the second connecting portion 112 and the air intake sealing ring 113, while realizing the detachable design of the main body 32, the sealing and stability of the gas transmission can be ensured, so that the essence can be evenly and effectively pushed out to the beauty head 31.

[0229] [About the beauty head 31 and the negative pressure chamber 2]

[0230] In this embodiment, there are many ways to set the beauty head 31. One of the ways to set the beauty head 31 is to set it in a fixed manner. During installation, the beauty head 31 can be fixedly installed on the beauty instrument body 1, and the beauty instrument body 1 provides a support effect for the beauty head 31. Fig.13 As shown, the beauty head 31 can also be fixedly installed on the main body 32. In this case, the beauty head 31 and the main body 32 form a modular structure to facilitate one-time production.

[0231] The second setting method of the beauty head 31 is a detachable setting. For example, the beauty head 31 is detachably connected to the main body 32 through a connecting structure (such as a snap structure, a threaded structure, etc.), or the beauty head 31 is detachably connected to the beauty instrument body 1. At this time, the beauty head 31 can be disassembled and replaced individually, which is beneficial to maintaining the hygiene of the beauty head 31 and optimizing the skin care environment. It should be noted that the specific setting method of the beauty head 31 can be adjusted according to actual needs, and no specific restriction is made here. No matter what installation method the beauty head 31 adopts, as long as any of the above-mentioned schemes is adopted, it is evenly included in the scope of consideration of the alternative means of this scheme.

[0232] The following is a detailed description of the method of fixing the beauty head 31 as an example. Fig.13 The beauty head 31 is arranged on the main body 32, and the beauty head 31 is fixedly connected to the main body 32. Such an arrangement can realize the integrated production of the main body 32 and the beauty head 31. For the convenience of description, the main body 32 and the beauty head 31 constitute the beauty component 3 that can be integrated, and through the fixed installation method, it can ensure that the structure of the beauty component 3 is stable and not easy to loosen and fall off.

[0233] Reference Fig. 20 In order to further prevent the essence from flowing back into the second section of the negative pressure channel 4, an anti-backflow structure is provided at the beauty head 31 in this embodiment. Specifically, the anti-backflow structure realizes the anti-backflow function by extending the path of the airflow in the negative pressure cavity 2. In this embodiment, the negative pressure cavity 2 includes an outer cavity 21 and an inner cavity 22.

[0234] Specifically, please refer to Fig. 20The beauty head 31 includes a core body 31a and an adsorption sleeve 31b. The core body 31a is connected to the main body 32. The interior of the core body 31a is hollow, and the core body 31a forms an inner cavity 22 inside; the adsorption sleeve 31b is sleeved on the outside of the core body 31a, and the beauty component 3 also includes a sealing ring 7, which is respectively connected to the adsorption sleeve 31b and the core body 31a, thereby forming an outer cavity 21 between the core body 31a and the adsorption sleeve 31b, and one side of the adsorption sleeve 31b has an open structure, through which the outer cavity 21 can be connected to the outside; in addition, an inner and outer communicating hole 1001 is also penetrated on the core body 31a, and the inner and outer communicating hole 1001 can connect the outer cavity 21 with the inner cavity 22, and the inner cavity 22 is connected to the second section of the negative pressure channel 4. The airflow needs to flow through the outer cavity 21, the inner and outer connecting holes 1001 and the inner cavity before reaching the second section of the negative pressure channel 4. Extending the path of the airflow in the negative pressure cavity 2 is beneficial to reduce the possibility of the essence being sucked into the second section of the negative pressure channel 4 after being output by the beauty head 31.

[0235] Continue to refer to Fig. 20 Specifically, based on the settings of the first negative pressure pipe 41 and the second negative pressure pipe 42 mentioned above, the negative pressure channel 4 includes a first section and a second section. The first section is used to connect the liquid storage chamber 6 and the outer cavity part 21. Specifically, when connecting the liquid storage chamber 6 with the outer cavity part 21, one end of the first negative pressure pipe 41 can be connected to the connecting part 33, and the other end can be directly connected to the core body 31a. A core tube 8 is arranged in the core body 31a. One end of the core tube 8 is connected to the first section, and the other end of the core tube 8 is connected to the outer cavity part 21, so as to realize the connection between the liquid storage chamber 6 and the outer cavity part 21; the second section is used to connect the inner cavity part 22 with the negative pressure mechanism 5. Specifically, one end of the second negative pressure pipe 42 can be connected to the negative pressure mechanism 5, and the other end can be directly connected to the core body 31a. An interface for airflow to pass through is provided on the core body 31a, and the second negative pressure pipe 42 can be connected to the inner cavity part 22 through the interface.

[0236] Through the above arrangement, the negative pressure mechanism 5 is started, and the negative pressure mechanism 5 can form a negative pressure in the inner cavity through the negative pressure channel 4. At this time, under the action of the through hole, the outer cavity 21 is simultaneously formed with a negative pressure. At this time, because the outer cavity 21 is connected with the outside, when the beauty head 31 contacts the skin, the outer cavity 21 will adsorb the skin, and the adsorption sleeve 31b with a sleeve-shaped 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 21 has a negative pressure, the negative pressure channel 4 pumps the essence toward the outer cavity 21, so that the essence can adhere to the adsorption element 3123 and then be applied to the skin. The arrangement of the outer cavity 21, the inner and outer connecting holes 1001 and the inner cavity extends the path of the airflow. In this process, the essence overflowing from the adsorption element 3123 will adhere to the inner wall of the negative pressure cavity 2 as the airflow moves, thereby playing a certain anti-backflow effect.

[0237] Specifically, please refer to Fig. 20 The core body 31a includes a core seat 311, one side of the core seat 311 is connected to the main body 32, and the core seat 311 is hollow inside to form the inner cavity 22. Specifically, the core seat 311 is a shell structure with one end closed, the closed end of the core seat 311 is connected to the main body 32, and is provided with the aforementioned interface communicating with the second negative pressure pipe 42.

[0238] The core tube 8 includes a tube head 81 and a tube body 82. The tube head 81 closes the open end of the core seat 311 so that the internal space of the core seat 311 forms an inner cavity 22 (that is, the tube head 81 covers the opening of the inner cavity 22). The tube body 82 extends toward the inner cavity 22 on one side of the tube head 81 and passes through the closed end of the core seat 311 to be connected to the first negative pressure pipe 41. The core seat 311 is provided with a through-tube hole 1007, and the tube body 82 is connected to the first negative pressure pipe 41 and the outer cavity 21 through the through-tube hole 1007.

[0239] The inner and outer communicating holes 1001 connecting the outer cavity 21 and the inner cavity 22 are formed on the core seat 311 and are located on the side close to the closed end of the core seat 311, that is, on the side close to the main body 32. This arrangement can extend the distance between the inner and outer communicating holes 1001 and the open end, thereby extending the flow path of the airflow in the outer cavity 21. In addition, the core seat 311 is also provided with an extension tube 313, which extends into the inner cavity 22 at the interface connected to the second negative pressure pipe 42 to connect the negative pressure mechanism 5 with the inner cavity 22. One end of the extension tube 313 extending into the inner cavity is located on the side away from the inner and outer communicating holes 1001.

[0240] Such a configuration can further extend the flow path of the airflow in the inner cavity 22. The outer cavity 21, the inner and outer connecting holes 1001, and the inner cavity 22 are equivalent to forming a flow path with multiple bends, which comprehensively extends the flow path of the entire airflow in the entire outer cavity 21 and the inner cavity 22. The path will drive the airflow and the essence overflowing from the adsorption element 3123 to make multiple bends. More essence flowing with the airflow will adhere to the inner wall of the negative pressure cavity 2 due to inertia at the bend, thereby further improving the anti-backflow effect.

[0241] Further, refer to Fig.21 In order to realize the application of essence, in one embodiment, the adsorption element 3123 is installed on the core body 31a, the adsorption element 3123 is located in the outer cavity 21, and is located at the outermost side of the core body 31a, the core body 31a is connected to the first section of the negative pressure channel 4, and the essence can flow directly from the first section of the negative pressure channel 4 and the core tube 8 to the adsorption element 3123.

[0242] Optionally, the adsorption element 3123 can be a component with many holes such as a sponge block, a porous silica gel block, or a porous ceramic block. These materials have a strong liquid absorption capacity due to their porous structure. They can absorb and retain a large amount of essence, so that the essence can be more evenly and continuously delivered during the delivery process, and the use effect will not be affected by the change of instantaneous flow rate.

[0243] In this embodiment, the adsorption element 3123 adopts a kind of elastic structure, such as a liquid storage sponge or a porous silicone block and other soft materials, which are skin-friendly and more comfortable to use. The user can directly contact the sponge or porous silicone block with the skin to achieve the liquid discharge function of the beauty head 31. This embodiment specifically adopts a sponge structure, which has a good liquid storage function and good resilience, and can give users a good experience when applying essence liquid directly in contact with the skin.

[0244] Alternatively, in some other embodiments, in order to achieve the liquid storage function, the adsorption element 3123 can also be a cavity for storing the essence liquid in the core body 31a. Specifically, the cavity in the core body 31a is directly connected to the core tube 8, and the liquid outlet 1002 is provided on the core body 31a, and the liquid outlet 1002 is connected to 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. On the one hand, it helps to control the production and assembly costs and improve production efficiency; on the other hand, it is also easy to clean and improves hygiene and safety.

[0245] For further information, please refer to Fig. 22 In order to optimize the liquid discharge effect, in one embodiment, the core body 31a also includes an application unit 3121, and the application unit 3121 is a shell-like structure. The application unit 3121 is movably connected to the other side of the core seat 311, and the application unit 3121 is located on the side of the core body 31a close to the skin, that is, the outermost side, and a liquid outlet 1002 is provided on the application unit 3121, and the liquid outlet 1002 is connected to the through-tube hole 1007 of the core seat 311.

[0246] In addition, the adsorption element 3123 is arranged between the core seat 311 and the application unit 3121. Since the adsorption element 3123 is an elastic structure, the application unit 3121 and the core body 31a core seat 311 can squeeze the adsorption element 3123 to deliver the essence to the skin through the liquid outlet 1002. Through this arrangement, when in use, the pressure can be changed to control the liquid output, which makes it more flexible and convenient to use.

[0247] For further information, please refer to Fig. 20The core 31a also includes an elastic member 314, which is preferably a spring structure, and the elastic member 314 is located between the core seat 311 and the applying unit 3121. Specifically, the two ends of the elastic member 314 can be fixedly connected to the core seat 311 and the applying unit 3121 respectively, and 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 applying unit 3121, so that the structure can rebound and reset faster, and the convenience of use and skin feel experience are optimized and improved.

[0248] Furthermore, in order to promote the absorption of the essence, the application unit 3121 is also provided with microneedles. Fig. 20 A microneedle chip 3122 may be installed on the outermost side of the application unit 3121, or a nano-microneedle structure may be directly formed on the application unit 3121, that is, the application unit 3121 itself is a microneedle chip 3122. Through the above arrangement, the nano-microneedles on the application unit 3121 or the microneedle chip 3122 may form micro-channels on the skin by stimulating the skin, thereby promoting the absorption of the essence.

[0249] In the specific configuration, the liquid outlet 1002 is opened on the microneedle wafer 3122, the microneedle wafer 3122 is connected to the main body 32 and is located at the outermost side of the beauty head 31, and the adsorption element 3123 is connected to the main body 32 and is located between the microneedle wafer 3122 and the main body 32. In this configuration, the microneedle wafer 3122 is indirectly disposed on the main body 32 through the adsorption element 3123, and one side of the adsorption element 3123 is connected to the first section of the negative pressure channel 4, and the other side is connected to the liquid outlet 1002, and at this time, the first section of the negative pressure channel 4 is connected to the liquid outlet 1002.

[0250] It is understandable that in the manner of installing the microneedle chip 3122 on the outermost side of the application unit 3121, the application unit 3121 is provided with a flow hole corresponding to the liquid outlet 1002 on the microneedle chip 3122, so that the essence can be smoothly transferred from the adsorption element 3123 to the liquid outlet 1002.

[0251] Through the above arrangement, the essence can flow directly into the adsorption element 3123. Since the microneedle chip 3122 is located at the outermost side of the beauty head 31, it can stimulate the skin. At the same time, in this process, the microneedle chip 3122 can squeeze the adsorption element 3123, so that the essence flows out from the liquid outlet 1002. While applying the essence, it is convenient for the essence to penetrate into the skin from the microchannel formed by the stimulation of the microneedle chip 3122, thereby improving the absorption of the essence.

[0252] In addition, the setting position of the liquid outlet 1002 may not be on the microneedle chip 3122. Specifically, the microneedle chip 3122 and the adsorption element 3123 are both connected to the main body 32 and are arranged adjacent to each other. The adsorption element 3123 is connected to the first section of the negative pressure channel 4. At this time, the porous structure of the adsorption element 3123 forms the liquid outlet 1002.

[0253] [About optimization of essence application]

[0254] In the above-mentioned method of applying the essence through the adsorption element 3123 or the application unit 3121, the adsorption element 3123 or the application unit 3121 contacts the skin only after the adsorption sleeve 31b contacts the skin and forms a negative pressure area, thereby applying the essence to the skin. In this method, the amount of essence applied is small and there is also an uneven problem. In order to make the application of the essence more uniform, the permeability is higher, and the use experience of the beauty instrument is optimized, the beauty instrument of this embodiment also includes a vibration mechanism 9 for driving the beauty head 31 to reciprocate.

[0255] Reference Figure 3 , Fig.23 and Fig.24 In one embodiment, the vibration mechanism 9 is disposed in the beauty instrument body 1, and includes a vibration motor 91. The vibration motor 91 is connected to the beauty head 31 in a transmission manner to drive the beauty head 31 to reciprocate, so that the beauty instrument can achieve stable application of the essence while also being able to massage the skin to promote the absorption of the essence. The application accuracy is high and the application effect is uniform, which improves the user experience. In particular, when the beauty head 31 is provided with a microneedle chip 3122, the vibration mechanism 9 applies regular and precise vibration to the beauty head 31, which helps to form a skin microchannel with uniform depth on the skin and increase the uniformity of the essence penetration. Optionally, the vibration motor 91 can adopt an eccentric vibration motor 91, which has the functions of compact size and stable vibration, and well meets the required working conditions.

[0256] In another embodiment, the beauty head 31 can also be directly connected to the vibration motor 91, that is, the beauty head 31 can be directly connected to the vibration motor 91 without setting the main body 32. This setting has a simple structure and low manufacturing cost. In this embodiment, in order to take into account the realization of the vibration and negative pressure absorption and application of essence, the negative pressure channel 4 can be set as a hose. In addition, the beauty head 31 can be detachably connected to the vibration motor 91 to facilitate the replacement of the beauty head 31.

[0257] Please continue to refer to Fig.23 and Fig.24, the following is an example of an embodiment in which the beauty head 31 is connected to the vibration mechanism 9 through the main body 32. In this embodiment, the beauty head 31 is connected to one end of the main body 32, and the vibration motor 91 is connected to the other end of the main body 32. The vibration motor 91 can drive the main body 32 to drive the beauty head 31 to reciprocate. Through this setting, the entire beauty component 3 can be driven by the vibration mechanism 9, and the negative pressure channel 4 can be integrated on the main body 32 while satisfying the vibration function, further taking into account the compactness of the structure. It can be understood that in order to take into account the realization of the vibration and negative pressure absorption and application of essence liquid functions, the negative pressure channel 4 is connected to the negative pressure mechanism 5 through a hose.

[0258] In this embodiment, the connection between the vibration mechanism 9 and the main body 32 can be set in two ways. First, the main body 32 is fixedly set on the vibration mechanism 9. The advantage of this setting is that the connection method of the main body 32 is simple and the structure is relatively strong; second, the main body 32 is detachably set on the vibration mechanism 9. In this setting, the main body 32 is set as a consumable, and the negative pressure channel 4 for conveying the essence can be updated by replacing the main body 32, thereby improving hygiene and safety.

[0259] Specifically, in this embodiment, when the main body 32 is detachably arranged on the vibration mechanism 9, the vibration mechanism 9 may further include a vibration connecting member 92, which is a sleeve-shaped structure, and the main body 32 is detachably connected to the vibration connecting member 92; wherein, one side of the vibration connecting member 92 is open, and the opening contour and size are adapted to the main body 32. At this time, the main body 32 can be plugged and installed on the vibration connecting member 92 to achieve structural positioning, so as to facilitate disassembly and connection.

[0260] At the same time, the vibration connector 92 is transmission-connected to the vibration motor 91. Specifically, a transmission rod is provided on the vibration connector 92. The vibration connector 92 is connected to the output shaft of the vibration motor 91 through the transmission rod, and the peripheral side of the vibration connector 92 is in sliding contact with the inner peripheral wall of the beauty instrument body 1, so that the vibration connector 92 can slide back and forth in the beauty instrument body 1. When vibrating, the main body 32 and the beauty head 31 are also vibrated back and forth along the length direction of the beauty instrument body 1.

[0261] In addition, in the setting of the beauty kit using the container 61 to store the essence, a second avoidance opening 921 is also provided on the vibration connector 92 of the beauty instrument. The second avoidance opening 921 is used to expose the connection portion 33 located on the main body 32 for the disassembly and assembly of the container 61. Under the above structural setting, the vibration motor 91 can drive the vibration connector 92 to reciprocate, and at the same time can meet the disassembly and installation of the container 61. More importantly, the user can disassemble the entire main body 32. At this time, it can avoid liquid remaining in the negative pressure channel 4 located in the main body 32, that is, avoid liquid remaining in the first negative pressure pipe 41 and the second negative pressure pipe 42, so as to reduce the possibility of bacterial growth, which is safe and hygienic.

[0262] It should be explained that the vibration connector 92 can be arranged outside the beauty instrument body 1. In this case, only the second avoidance opening 921 can be arranged to expose the connection portion 33. However, in order to meet the requirements of structural stability and compactness, the vibration connector 92 can be arranged outside the beauty instrument body 1. Fig.23 Combined with Figure 2 In the solution shown in this embodiment, the vibration connecting member 92 is arranged in the beauty instrument body 1, wherein one end of the beauty instrument body 1 is provided with an installation opening 102 for the main member 32 to be disassembled and assembled. The installation opening 102 can enable the beauty component 3 to be installed inside the beauty instrument body 1, play a role of avoidance and is used for the beauty component 3 to be disassembled and assembled. Correspondingly, the first avoidance opening 101 on one side of the beauty instrument body 1 corresponds to the second avoidance opening 921, and the container 61 can be detachably connected to the connecting portion 33 through the first avoidance opening 101 and the second avoidance opening 921 in sequence.

[0263] Furthermore, the length of the first avoidance opening 101 in the vibration direction of the main body 32 needs to be greater than the length of the second avoidance opening 921 in the vibration direction of the main body 32 to avoid vibration interference between the container 61 and the beauty instrument body 1 when the beauty component 3 vibrates.

[0264] Reference Fig.24 When the main body 32 and the vibration mechanism 9 are disassembled and connected, the connection between the negative pressure channel 4 and the negative pressure mechanism 5 also needs to be guaranteed accordingly to avoid leakage during the disassembly process. Specifically, in this embodiment, the vibration connection member 92 is provided with the aforementioned connecting portion 11, which is a columnar tube structure, and the two ends of the connecting portion 11 extend to the outside and the inside of the vibration connection member 92 respectively. At the same time, the hollow part of the connecting portion 11 forms a connecting channel, and the negative pressure mechanism 5 is connected to the negative pressure channel 4 via the connecting portion 11.

[0265] In the specific setting, the multi-way valve 54 and the outer side of the connecting part 11 are connected by adding a pipeline to realize the connection between the negative pressure mechanism 5 and the connecting part 11, and a recess structure is also provided on the main body 32 for plugging and positioning with the inner section of the connecting part 11. The bottom of the recess structure has a through hole, and the second section of the negative pressure channel 4 is connected to the connecting channel through the through hole. For the convenience of distinction, the recess located on the main body 32 is defined as the first connecting part 111, and the connecting part 11 provided on the vibration connecting part 92 is defined as the second connecting part 112. Based on this setting, the main body 32 and the vibration connecting part 92 can be plugged in and positioned through the connecting part 11 and the recess. 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 prone to air leakage.

[0266] In other embodiments, the second connecting portion 112 can also be set as a recessed structure in reverse. In this case, a corresponding protruding structure needs to be set on the main body 32. The negative pressure channel 4 and the negative pressure mechanism 5 can also be connected when the main body 32 is disassembled by means of plug-in positioning. It can be understood that the structures of the first connecting portion 111 and the second connecting portion 112 are swapped. No matter which method is adopted, the plug-in positioning scheme that can achieve precise docking and connection between the main body 32 and the vibration connector 92 should be regarded as an equivalent means of this scheme.

[0267] Further, refer to Fig.25 In order to realize convenient disassembly between the vibration connector 92 and the main body 32, the vibration connector 92 is installed with an elastic fastener 922, wherein a receiving opening can be opened on the peripheral side of the vibration connector 92, and the elastic fastener 922 is located in the receiving opening, so that the compactness of the structure can be improved. Correspondingly, a fastening portion 923 movably fastened to the elastic fastener 922 is provided at the corresponding position of the main body 32, and the elastic fastener 922 has a barb, and the fastening portion 923 is a concave structure. Under the action of the elastic fastener 922 and the fastening portion 923, the main body 32 and the vibration connector 92 can be quickly plugged in and out, and the operation is convenient. In addition, there can be an obvious sense of jamming in the assembly process, so that the user can feel whether the assembly is in place, and the user experience is good.

[0268] It needs to be explained that the setting positions of the elastic fastener 922 and the snap-on portion 923 can be swapped. For example, the elastic fastener 922 can be set on the main body 32, and the snap-on portion 923 can be set on the elastic connector, which can also achieve the mutual snap-on effect. In addition, the two can also be detachably connected by means of magnetic attraction, threaded connection, etc. Any structure that can achieve detachable connection can be tried and should be included in the scope of interpretation of detachable connection.

[0269] [Detailed settings of the beauty head 31]

[0270] Further, refer to Fig.26 Based on the above structural setting, this embodiment can obtain a beauty head 31 and a beauty instrument, which are used to further optimize the uniform liquid delivery effect of the beauty head 31.

[0271] The following first introduces the use of the beauty instrument by taking the storage of the essence in the container 61 as an example:

[0272] S10: The beauty instrument is brought close to the human skin so that the human skin blocks the opening of the outer cavity 21; then, the negative pressure mechanism 5 applies negative pressure to the outer cavity 21 so that the air pressure of the outer cavity 21 drops to be lower than the internal air pressure of the container 61. Under the action of the pressure difference, the essence in the container 61 is transported to the beauty head 31 through the liquid outlet channel 1004, and then transported to the human skin through the liquid outlet 1002 of the beauty head 31;

[0273] S20: The vibration mechanism 9 drives the beauty head 31 to perform a micro-vibration in the front-to-back direction. During the vibration process, the beauty head 31 will continuously stimulate the human skin and promote the absorption of the essence by the human skin;

[0274] Optionally, the vibration mechanism 9 is a cam-connecting rod mechanism, or the vibration mechanism 9 is a linear drive mechanism, etc., which is not limited in this embodiment. Further, the linear drive mechanism can be a cylinder, a hydraulic cylinder, an electric cylinder, or a motor screw linear module, etc.

[0275] To this end, in order to optimize the beauty effect of the beauty head 31 , the beauty head 31 in this embodiment is further introduced in detail below.

[0276] Reference Fig. 27 The beauty head 31 provided in this embodiment includes a core tube 8, a liquid outlet component 312, and an adsorption element 3123. The core tube 8 is provided with an in-tube liquid delivery hole 821. The liquid outlet component 312 is connected to the core tube 8 and cooperates with the core tube 8 to surround and form a closed buffer cavity 1006; wherein the liquid outlet component 312 is provided with a liquid outlet 1002 connecting the buffer cavity 1006 to the external space of the beauty head 31. The adsorption element 3123 is a multi-porous structure, and the adsorption element 3123 is located in the buffer cavity 1006.

[0277] The beauty head 31 and beauty instrument provided in this embodiment, on the one hand, when the liquid delivery hole 821 in the tube delivers the essence to the buffer chamber 1006, the essence will first enter the internal holes of the adsorption element 3123. When the internal holes of the adsorption element 3123 are filled with the essence, the essence will flow out through the liquid outlet 1002. In this process, the adsorption element 3123 is a porous structure with a large liquid storage space, which can temporarily store the essence, thereby adjusting the speed and amount of the essence flowing out of the liquid outlet 1002. In this way, even if the supply of the essence through the liquid delivery hole in the tube fluctuates, the beauty head 31 can ensure that the flow rate of the essence delivered out through the liquid outlet is relatively stable, thereby avoiding the problem of uneven or discontinuous delivery of the essence due to changes in the supply amount;

[0278] On the other hand, when the negative pressure mechanism 5 applies negative pressure to the outer cavity 21, the adsorption element 3123 can cache the essence in the buffer cavity 1006, control the liquid output from the liquid outlet 1002, and prevent a large amount of essence from directly flowing out through the liquid outlet 1002 and being directly sucked back by the negative pressure mechanism 5 in the outer cavity 21, resulting in a waste of essence.

[0279] Optionally, the core tube 8 and the liquid outlet component 312 are slidably sealed and connected, and a spring 3141 is provided in the buffer chamber 1006 to abut against the core tube 8 and the liquid outlet component 312 respectively; wherein the spring 3141 is used to drive the liquid outlet component 312 to move in a direction away from the adsorption element 3123.

[0280] The design of the spring 3141 enables the beauty head 31 to automatically adjust the amount of liquid discharged according to the pressure of the skin contact. Specifically, the function of the spring 3141 is to balance the internal and external pressures. When the external pressure decreases, the spring 3141 pushes the liquid discharge component 312 to reduce the amount of liquid discharged, and vice versa. This ensures the stable delivery of the essence liquid, which is not affected by the user's operating force.

[0281] 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 compactness of the beauty head 31.

[0282] Alternatively, the number of springs 3141 is at least two, and each spring 3141 is evenly 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; alternatively, the number of springs 3141 is three, and the three springs 3141 are arranged in an equilateral triangle, and the adsorption element 3123 is located at the center of the equilateral triangle; alternatively, 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. Multiple springs 3141 are evenly arranged, which can provide more stable support and pressure balance, and ensure uniform output of the essence.

[0283] In this embodiment, the beauty head 31 further includes a core base 311. The core base 311 is provided with an inner cavity portion opening toward the adsorption element 3123, an extension tube 313 connecting the inner cavity portion to the negative pressure mechanism 5, an inner and outer communication hole 1001 connecting the inner cavity portion to the outer cavity portion 21, and a through-tube hole 1007 connecting the inner cavity portion to the external space of the core base 311.

[0284] Correspondingly, the core tube 8 includes a tube head 81 and a tube body 82. The tube head 81 is sleeved on the core seat 311 to cover the opening of the inner cavity 22; one end of the tube body 82 is fixed to the tube head 81 and communicates with the buffer cavity 1006, and the other end passes through the tube hole 1007 and extends to the external space of the inner cavity 22 to connect with the liquid outlet channel 1004. Among them, the inner tube liquid delivery hole 821 is located in the tube body 82.

[0285] When the negative pressure mechanism 5 is evacuating air, the air in the outer cavity 21 will be pumped into the negative pressure mechanism 5 through the inner and outer connecting holes 1001, the inner cavity 22, and the extension tube 313 in sequence, thereby realizing the negative pressure pumping treatment of the outer cavity 21; when the internal air pressure of the outer cavity 21 drops, the essence liquid in the container 61 can be transported to the adsorption element 3123 of the buffer cavity 1006 through the liquid outlet channel 1004 and the liquid delivery hole 821 in the tube.

[0286] In this embodiment, the liquid outlet component 312 includes an application unit 3121 provided with an open groove, and a microneedle chip 3122 located on the side of the application unit 3121 away from the adsorption element 3123; wherein, the application unit 3121 is provided with a unit through hole 3124 connected to the buffer cavity 1006, and the liquid outlet 1002 is located on the microneedle chip 3122 and is connected to the unit through hole 3124.

[0287] The head of the core tube 8 is inserted into the open groove, wherein the core tube 8, the groove wall of the open groove, and the groove bottom of the open groove surround and form a buffer cavity 1006. Further, the circumferential surface of the head of the core tube 8 is sleeved with a sealing member 315 abutting against the groove wall of the open groove.

[0288] The open slot design allows the core tube 8 to be inserted and form a buffer chamber 1006, which is convenient for assembly and maintenance. When the vibration mechanism 9 drives the application unit 3121 to vibrate and press the human skin repeatedly, the microneedle wafer 3122 can help the essence to penetrate the skin more deeply through the tiny pinholes.

[0289] Optionally, the circumferential surface of the head of the core tube 8 is provided with a tube circumferential boss 811, and the groove wall of the open groove is provided with a groove wall limiting boss 3125; wherein the groove wall limiting boss 3125 abuts against the surface of the tube circumferential boss 811 facing away from the adsorption element 3123 to limit the core tube 8 from escaping from the application unit 3121 through the groove of the open groove. Through the cooperation of the tube circumferential boss 811 and the groove wall limiting boss 3125, the movement of the core tube 8 relative to the liquid outlet component 312 is limited, ensuring the relative position stability between the two, thereby ensuring the stability of the essence delivery.

[0290] In summary, the beauty head 31 and the beauty instrument provided in this embodiment, after being combined with the vibration mechanism 9, have the following advantages:

[0291] ① The porous adsorption element 3123 can not only buffer the essence, but also 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, and can also control the liquid output under negative pressure environment, preventing the essence from being sucked by the negative pressure mechanism 5, thereby reducing waste;

[0292] ② The design of the spring 3141 enables the beauty head 31 to automatically adjust the liquid output according to the skin contact pressure, thereby ensuring the stable delivery of the essence;

[0293] ③ The core seat 311, the core tube 8, and the liquid outlet component 312 are plugged in sequence, and the assembly and disassembly are simple and convenient, which is convenient for assembly and maintenance.

[0294] [Regarding the sealing setting of the negative pressure chamber 2]

[0295] After the beauty instrument is provided with the vibration mechanism 9 and the beauty component 3, since a negative pressure cavity 2 needs to be formed, and vibration easily causes air leakage in the negative pressure cavity 2, for this reason, the present embodiment also discloses a sealing solution that can achieve a stable adsorption effect under vibration conditions.

[0296] Reference Fig.28, wherein the beauty instrument includes a core 31a, an adsorption sleeve 31b and a sealing ring 7. The core 31a is used to connect with a vibration mechanism 9 (not shown in the figure), and the vibration mechanism 9 can drive the core 31a to vibrate back and forth to achieve a vibration massage effect. The specific structure of the core 31a can be adjusted according to actual needs, and will not be described in detail here; in order to achieve the adsorption function, the core 31a includes a negative suction channel for gas transmission. It can be understood that the negative suction channel can be composed of the extension tube 313 and the inner cavity 22 mentioned above, and its specific setting method is also not described in detail here.

[0297] The core body 31a is arranged in the adsorption sleeve 31b, and a negative pressure cavity 2 connected to the negative suction channel is formed between the core body 31a and the adsorption sleeve 31b, and 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, thereby forming a negative pressure area in the negative pressure cavity 2 that can adsorb the skin.

[0298] It is understandable that in order to obtain the appropriate adsorption strength, it is more appropriate to control the air pressure in the negative pressure area in the range of -20kpa to -40kpa. The specific values ​​can be selected as -20kpa, -30kpa or -40kpa, etc. The air pressure in the negative pressure area can be set based on the skin feel and specific adsorption requirements; among them, for users with sensitive skin, an air pressure of -20kp can be used for adsorption, so that a smaller adsorption strength can be obtained, which is not easy to cause marks on the skin, so as to avoid redness and itching; and under the condition of -30kpa, the adsorption strength is moderate, which is suitable for the skin type of most users, and when the air pressure is -40kpa, it can provide a larger adsorption force, which is suitable for users who can tolerate large suction and are prone to positional displacement during use, such as users with oily skin. Therefore, by controlling the air pressure in the range of -20kpa to -40kpa, users can get a good experience, and the specific value of the air pressure can be adjusted accordingly according to the actual design, and no specific restrictions are made here.

[0299] Furthermore, during the negative pressure adsorption process, in order to further enhance the overall skin feel, the thickness of the adsorption sleeve 31b can be set between 0.8-2.8mm, for example, 0.8mm, 1.4mm or 2.8mm can be selected, and chamfers can be set on the edges of the adsorption sleeve 31b, with the range of chamfers being between 0.3mm-0.8mm, and 0.3mm, 0.5mm or 0.8mm can be selected.

[0300] Optionally, the thickness setting range of the adsorption sleeve 31b can be set according to skin quality requirements. For example, users with sensitive skin are suitable for a thicker 2.8mm one. At this time, the pressure on the skin during adsorption can be reduced by increasing the thickness, making the skin less prone to redness, swelling and itching. In addition, an adsorption sleeve 31b with a thickness of 1.4mm can be suitable for most neutral skin and most users. When the thickness of the adsorption sleeve 31b is set to 0.8mm, it can generate a greater pressure on the skin during the adsorption process, and can adsorb the skin more stably, which is suitable for users with oily skin and makes it less likely to deviate during adsorption.

[0301] Optionally, the chamfer setting can also be adjusted accordingly with reference to the thickness of the suction sleeve 31b. The chamfer is preferably a single-sided chamfer structure, and a circular arc chamfer structure can be adopted. The chamfer is made as large as possible within the thickness limit, and only a part of the plane needs to be retained. For example, when the thickness of the suction sleeve 31b is set to 0.8mm, the chamfer size is selected to be 0.3mm, and when the thickness of the suction sleeve 31b is 1.4mm, the chamfer size is 0.5mm, and when the thickness of the suction sleeve 31b is 2.8mm, the chamfer size is 0.8mm.

[0302] The above values ​​are not specifically limited in combination. When the adsorption sleeve 31b is within the above thickness range and chamfer range, a contact surface with an arc can be formed, so that it is not easy to leave marks during adsorption, and the skin feel is optimized and improved.

[0303] Reference Fig.28 and Fig.29 In one embodiment, the sealing ring 7 is located between the core body 31a and the adsorption sleeve 31b in this embodiment, and the sealing ring 7 is respectively connected to the core body 31a and the adsorption sleeve 31b, and is used to seal the gap between the core body 31a and the adsorption sleeve 31b to form a negative pressure cavity 2 with good sealing performance. Furthermore, the sealing ring 7 has an elastic deformation portion 73, and the elastic deformation portion 73 is used to provide elastic buffering for the core body 31a and the adsorption sleeve 31b.

[0304] In the above scheme, the sealing ring 7 can seal the gap between the core body 31a of the beauty head 31 and the suction sleeve 31b. At the same time, by arranging the elastic deformation part 73 on the sealing ring 7, the elastic deformation part 73 can give the sealing ring 7 elastic and retractable freedom of movement. At this time, when the beauty head 31 is in a vibrating use condition, the suction sleeve 31b and the core body 31a can always maintain a good sealing effect, and it is not easy to leak during vibration. Moreover, the impact force of the suction sleeve 31b on the skin during vibration can be reduced, providing a better experience.

[0305] At the same time, it can be understood that when the suction sleeve 31b is connected to the core body 31a, the condition that the core body 31a is located inside the suction sleeve 31b roughly includes three position states. In the first position state, the core body 31a does not exceed the opening of the suction sleeve 31b; the second is that the end face of the core body 31a is flush with the opening; the third is that the core body 31a slightly exceeds the opening of the core body 31a; under the above three position relationships, the suction sleeve 31b can be more stably adsorbed to the skin. Among them, if the core body 31a exceeds the opening of the suction sleeve 31b too much, because the softness of the skin is limited, it cannot be well covered on the suction sleeve 31b, resulting in the phenomenon of loose adsorption. Therefore, in order to ensure good adsorption strength, the above three setting states are adopted between the core body 31a and the suction sleeve 31b.

[0306] Preferably, the first position state setting is adopted in this embodiment, and the distance between the microneedle wafer 3122 and the opening of the adsorption sleeve 31b is controlled to be 0.5mm-1.5mm, specifically 0.5mm, 1mm or 1.5mm. The distance between the microneedle wafer 3122 and the opening of the adsorption sleeve 31b should be set corresponding to the degree of stimulation of the user. It can be known that when the distance between the openings of the two is larger, it indicates that the movement stroke of the microneedle is larger, and the longer the stroke, the greater the compression degree of the elastic member 314, and the greater the force on the skin. Therefore, on the one hand, different pain sensations will be generated, and on the other hand, it may also cause redness and swelling to sensitive skin.

[0307] Based on this, when the distance between the microneedle chip 3122 and the opening of the adsorption sleeve 31b is set to 0.5mm, the stimulation intensity can be reduced to meet the needs of users with low pain tolerance and sensitive skin; in addition, when the distance between the microneedle chip 3122 and the opening of the adsorption sleeve 31b is set to 1mm, the stimulation intensity is moderate and suitable for most users. In addition, when the distance between the microneedle chip 3122 and the opening of the adsorption sleeve 31b is set to 1.5mm, it can be used for puncture for users with thick stratum corneum to achieve deep penetration of the essence and optimize the beauty effect.

[0308] Under the above distance setting, the distance is adjusted according to different needs so that the skin can just touch the microneedle chip 3122 after negative pressure adsorption. Combined with the vibration effect of the vibration mechanism 9, it can reduce the pain and discomfort caused by excessive puncture force when the skin is pierced. The massage force is moderate and the skin feel is optimized. The specific distance value in the actual setting is not limited here.

[0309] Specifically, in one embodiment, the elastic deformation part 73 can be formed of a soft elastic material, for example, the elastic deformation part 73 is set to a silicone or rubber structure. At this time, the elastic deformation part 73 has an elastic expansion effect, and can provide sealing and elastic buffering functions to meet the use conditions.

[0310] It should be explained that if the material of the elastic deformation part 73 is simply changed, the sealing ring 7 itself may also produce the possibility of disordered deformation. For example, in actual application, the adsorption sleeve 31b will not only vibrate linearly along the axis of vibration, but also with the user's operation, such as moving the adsorption position, a vertical displacement perpendicular to the axis of vibration will be applied to the adsorption sleeve 31b. At this time, the structure of the elastic deformation part 73 adopts a conventional straight tube structure, which may cause lateral deformation and thus lead to air leakage.

[0311] Reference Fig.29 In order to overcome the above-mentioned technical obstacles, in the present embodiment, the elastic deformation portion 73 includes a corrugated section 731 bent toward one side, and the corrugated section 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. At this time, the corrugated section 731 can provide certain support for the elastic deformation portion 73 to reduce the tendency of vertical deformation, and the bent section can provide vibration guidance for the sealing ring 7, so that it can better withstand the elastic buffering force, and the vibration sealing performance is guaranteed to a certain extent.

[0312] It is understandable that the corrugated section 731 can be set in a plurality of adjacent combinations during the actual setting process, and a single corrugated section 731 can be bent inward or outward, and the specific bending direction can be adjusted according to actual needs. In this embodiment, the inward bending method is used as a demonstration, and the inward bending method is conducive to the assembly of the sealing ring 7 in a small space. In addition, in another embodiment, the corrugated section 731 can also be replaced with other similar structures, such as a sawtooth structure. Any structure that can achieve telescopic buffering can be tried and should be included in the protection scope of this application.

[0313] Further, refer to Fig.30 as well as Fig.31In another embodiment, in order to optimize the elastic deformation part 73's resistance to deformation perpendicular to the vibration direction, the elastic deformation part 73 also includes a reinforcement section 732, and the reinforcement section 732 is recessed toward the inner side of the sealing ring 7. In this embodiment, an inwardly recessed structure is adopted. Based on the above arrangement, the reinforcement section 732 enables the elastic deformation part 73 to form mutually staggered first step surfaces 733 and second step surfaces 734 at the outer peripheral surface. The reinforcement section 732 between the first step surface 733 and the second step surface 734 is perpendicular to the vibration direction 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.

[0314] It can be understood that the number of reinforcement segments 732 can be multiple groups, and different reinforcement segments 732 can be selectively arranged in the elastic deformation portion 73 in the form of bending toward the outside or the inside, and can be combined arbitrarily to provide the function of resisting vertical deformation. In this embodiment, only one group of reinforcement segments 732 is shown, and the reinforcement segments 732 are recessed toward the inside.

[0315] In addition, refer to Fig.31 The thickness at the intersection of the first step surface 733 and the second step surface 734 can also be set to be greater than the thickness of the area where the first step surface 733 or the second step surface 734 is located, which is equivalent to thickening the recessed position of the reinforcement section 732. At this time, the structural strength of the reinforcement section 732 can be further optimized and improved.

[0316] Continue to refer to Fig.30 and Fig.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.

[0317] To this end, the sealing ring 7 is made of silicone or rubber, and when the sealing ring 7 and the core body 31a are connected, the sealing ring 7 includes a first connecting portion 71 connected to the elastic deformation portion 73. Usually, the two are connected as one body to obtain good sealing; furthermore, the first connecting portion 71 includes a first fitting section 711 wrapped and fixed on the outer peripheral surface of the core body 31a. At this time, it is connected to the outer peripheral surface of the core body 31a by elastic wrapping or adhesive wrapping, so that a stable connection relationship with good sealing can be obtained.

[0318] Furthermore, on the basis of setting the first fitting section 711, the first connecting portion 71 also includes a first extending section 712 connected to the first fitting section 711, and the first extending section 712 extends and covers and is fixed on the end surface of the core body 31a. At this time, the first extending section 712 can further increase the wrapping property, thereby further optimizing the sealing property of the first connecting portion 71.

[0319] In addition, continue to refer to Fig.31 When the sealing ring 7 is connected to the adsorption sleeve 31b, the sealing ring 7 also includes a second connecting portion 72 connected to 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. The second connecting portion 72 and the elastic deformation portion 73 are usually connected as one piece to obtain good sealing performance; furthermore, the second connecting portion 72 includes a second fitting section 721 that is covered and fixed on the outer circumference or inner circumference of the adsorption sleeve 31b. In the present embodiment, the second connecting portion 72 is attached to the outer circumference of the adsorption sleeve 31b.

[0320] At this time, the second connecting portion 72 is fixed on the outer circumference or the inner circumference of the adsorption sleeve 31b by covering, so as to achieve mutual connection between the two. Such a configuration can have a larger contact area, thereby obtaining a better sealing effect.

[0321] Furthermore, in order to optimize the sealing between the sealing ring 7 and the core body 31a, the sealing ring 7 can also be matched with the main body 32. Specifically, the main body 32 is used to connect the core body 31a and the vibration mechanism 9; wherein the main body 32 and the core body 31a are sleeved together. In the present embodiment, the opening of the main body 32 is larger than the end face size of the core body 31a, so that the main body 32 can be sleeved to the outside of the core body 31a; furthermore, the first connecting portion 71 is located between the main body 32 and the core body 31a, and the opposite side surfaces of the first connecting portion 71 are respectively connected to the main body 32 and the core body 31a, which is equivalent to clamping the first connecting portion 71 between the main body 32 and the core body 31a. With this arrangement, the number of sealing surfaces is increased, which can further improve the overall sealing of the sealing ring 7.

[0322] Furthermore, a first sealing protrusion 713 can be provided on the core body 31a or the first connecting portion 71. In the present embodiment, the first sealing protrusion 713 is in a closed-loop structure, and because the sealing ring 7 is made of an elastic structure such as silicone or rubber, the first sealing protrusion 713 can block the gap between the first connecting portion 71 and the core body 31a, and the sealing performance between the core body 31a and the sealing ring 7 is optimized and improved.

[0323] It can be understood that multiple first sealing protrusions 713 can be provided, and a single first sealing protrusion 713 can be selectively provided on the core body 31a or the first connecting portion 71. Therefore, under the condition of multiple first sealing protrusions 713, the first sealing protrusions 713 are provided on the core body 31a and the connecting portion 33 respectively. In this embodiment, there is no restriction on the combination of the first sealing protrusions 713. No matter what combination is adopted, it should be included in the scope of interpretation of this application.

[0324] Furthermore, a second sealing protrusion 722 is provided on the adsorption sleeve 31b and / or the second connecting part 72. The setting method of the second sealing protrusion 722 is similar to that of the first sealing protrusion 713 and is not elaborated here. It can be understood that the second sealing protrusion 722 can block the gap between the second connecting part 72 and the adsorption sleeve 31b to increase the sealing between the core body 31a and the second connecting part 72.

[0325] Reference Fig.32 as well as Fig.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 other parts, thereby obtaining another sealing structure:

[0326] In this embodiment, the beauty instrument includes a beauty instrument body 1, a vibration mechanism 9, a beauty component 3 and a sealing ring 7. Among them, a negative pressure sleeve 1a is provided at one end of the beauty instrument body 1, and the negative pressure sleeve 1a has an opening, and the negative pressure sleeve 1a is equivalent to replacing the adsorption sleeve 31b mentioned above. In addition, the vibration mechanism 9 is provided on the beauty instrument body 1, and the beauty component 3 is connected to the vibration mechanism 9. The vibration mechanism 9 can drive the beauty component 3 to vibrate back and forth. The vibration mechanism 9 is used to drive the beauty component 3 to vibrate back and forth. The negative pressure sleeve 1a is sleeved on the outside of the beauty instrument, and the beauty component 3 is located inside the negative pressure sleeve 1a.

[0327] It can be understood that the arrangement of the beauty component 3 inside the negative pressure sleeve 1a includes three positional 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; the second is that the end face of the beauty component 3 is flush with the opening; the third is that the beauty component 3 slightly exceeds the opening of the beauty component 3; under the above three positional relationships, the negative pressure sleeve 1a can be more stably attracted to the skin.

[0328] Furthermore, the sealing ring 7 is made of an elastic material such as silicone or rubber, and includes a first connecting portion 71, an elastic deformation portion 73 and a second connecting portion 72 which are sequentially connected along the vibration direction. Preferably, the first connecting portion 71, the elastic deformation portion 73 and the second connecting portion 72 are integrally connected, thereby ensuring that the sealing ring 7 has good sealing properties.

[0329] It can be understood that, in this embodiment, the elastic deformation portion 73 includes a corrugated section 731 bent toward the inside and / or outside. Optionally, in this embodiment, a reinforcement section 732 can also be provided on the elastic deformation portion 73. The specific structures of the corrugated section 731 and the reinforcement section 732 are not described in detail here.

[0330] The first connection part 71 is connected to the beauty component 3, and the second connection part 72 is connected to the beauty 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 beauty component 3, so that a negative pressure cavity 2 is formed between the negative pressure sleeve 1a and the beauty component 3.

[0331] In the above technical solution, the elastic deformation part 73 located on the sealing ring 7 can enable the sealing ring 7 to adapt to elastic deformation, thereby being able to provide a sealing function under a vibration environment, and also being able to solve the problem of insufficient sealing under vibration conditions.

[0332] Optional, see Fig.33 In one embodiment, the first connecting portion 71 includes a first sealing arm 714, which extends toward the beauty component 3. The first sealing arm 714 is perpendicular to the vibration direction, and the end of the first sealing arm 714 is connected to the peripheral side of the beauty component 3. At this time, a sealing surface is formed between the end surface of the first sealing arm 714 and the beauty component 3 to achieve a sealing effect.

[0333] Optionally, in another embodiment, the first sealing arm 714 is also perpendicular to the vibration direction. Different from the end-touching method, the position of the beauty component 3 can be adjusted, and the first sealing arm 714 can be wrapped around the end face of the beauty component 3 to form a sealing surface. At this point, the first sealing arm 714 can achieve sealing by either end-face contact or end-face wrapping. In this embodiment, the first sealing arm 714 extends toward the beauty component 3, and the end of the first sealing arm 714 is connected to the peripheral side of the beauty component 3.

[0334] Furthermore, the first connection portion 71 further includes a second sealing arm 715. In this embodiment, the second sealing arm 715 is disposed adjacent to the first sealing arm 714, and one end of the first sealing arm 714 and one end of the second sealing arm 715 intersect with each other and are simultaneously connected to the elastic deformation portion 73. The difference between the second sealing arm 715 and the first sealing arm 714 is that the extension direction of the second sealing arm 715 is the same as the vibration direction, and the second sealing arm 715 is covered on the peripheral side of the vibration mechanism 9.

[0335] At this time, the second sealing support arm 715 can improve the connection stability of the first connecting part 71 on the one hand, and on the other hand, the second support arm and the vibration mechanism 9 form an additional sealing surface to further enhance the sealing effect of the first connecting part 71, thereby optimizing and improving the function.

[0336] Furthermore, in order to optimize the connection stability of the second sealing support arm 715, an interlocking step for embedding the second sealing support arm 715 is provided on the peripheral side of the vibration mechanism 9. At this time, the interlocking step can make the sealing ring 7 more accurately connected to the vibration mechanism 9 during assembly, which can improve the connection accuracy and connection stability between the sealing ring 7 and the vibration mechanism 9, and is conducive to improving the sealing performance.

[0337] Moreover, in this embodiment, the end of the first sealing arm 714 is connected to the beauty component 3. At this time, one side surface of the first sealing arm 714 can also be attached to the end face of the vibration mechanism 9 to form an additional sealing surface. The sealing effect is improved, and the vibration mechanism 9 can provide support for the first sealing arm 714, so that the first sealing arm 714 is not easily deformed during the vibration process, and is not easy to leak.

[0338] Continue to refer to Fig.32 as well as Fig.33 In order to ensure the connection stability and sealing performance of the second connecting part 72, the beauty instrument body 1 has an inner end surface perpendicular to the vibration direction of the beauty component 3. In this embodiment, the second connecting part 72 includes a first sealing segment 723, which is connected to the elastic deformation part 73, and the first sealing segment 723 extends in a direction perpendicular to the vibration direction and fits on the inner end surface to achieve the connection between the second connecting part 72 and the beauty instrument body 1. At this time, the second connecting part 72 is equivalent to providing support for the sealing ring 7, forming a fulcrum, which can meet the vibration sealing effect of the sealing ring 7.

[0339] However, it should be noted that this setting will make the sealing ring 7 close to the depth of the beauty instrument body 1, so it is necessary to consider the deformation space of the elastic deformation part 73 to meet the movement freedom requirement. By adjusting the size of the beauty component 3 and the length of the vibration mechanism 9, a gap can be formed between the cross-section of the beauty component 3 and the beauty body along the vibration direction, and the elastic deformation part 73 is located in the gap, so that the elastic deformation part 73 has space for elastic buffering.

[0340] Furthermore, in order to improve the connection stability between the second connecting portion 72 and the beauty instrument body 1, the beauty instrument body 1 also has an inner circumferential surface connected to the inner end surface, and the two are perpendicular to each other; the second connecting portion 72 also includes a second sealing segment 724 connected to the first sealing segment 723, and the two are connected as one body; the second sealing segment 724 fits with the inner circumferential surface, thereby widening the contact area between the second connecting portion 72 and the beauty instrument body 1, so that the sealing ring 7 is more stable and firm during assembly, and is not easy to loosen and leak.

[0341] Under the above structural setting, a sealing structure close to the inside of the beauty instrument body 1 and capable of providing elastic support is obtained, and the sealing structure can form a larger negative pressure cavity 2 to meet the needs of different beauty instrument products under different usage conditions. However, there is more than one sealing structure that can achieve the above function. Here, another structural structure that can achieve a vibration sealing effect is provided, which is also close to the inside of the beauty instrument body 1.

[0342] Reference Fig.34 as well as Fig.35 Specifically, the difference of this structure lies in the different structures of the first connecting part 71 and the second connecting part 72, wherein the first connecting part 71 is located between the beauty component 3 and the vibration mechanism 9, and the two opposite side surfaces of the first connecting part 71 are respectively connected to the beauty component 3 and the vibration mechanism 9. Through this arrangement, it is equivalent to clamping and assembling the first connecting part 71 between the two to form a stacked sealing structure, and the sealing effect is further optimized and improved.

[0343] Furthermore, the beauty component 3 has a step surface 1009 arranged opposite to the end surface of the vibration mechanism 9, and the step surface 1009 can be obtained by setting a step structure at the main body 32 of the beauty component 3. In addition, the first connecting portion 71 includes a first bending section 716 and a second bending section 717, the second bending section 717 is connected to the elastic deformation portion 73, the first bending section 716 is located on the side of the second bending section 717 away from the elastic deformation portion 73, the first bending section 716 is integrally connected with the second bending section 717, 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.

[0344] Based on this, the two opposite surfaces of the first bending section 716 are respectively connected to the beauty component 3 and the vibration mechanism 9, and the second bending section 717 is respectively in contact with the end surface of the vibration mechanism 9 and the step surface 1009. Here, by setting the first connecting portion 71 as the first bending section 716 and the second bending section 717, a bending sealing structure is formed, which is equivalent to forming a two-stage sealing structure, which can extend the sealing path and improve the sealing effect.

[0345] Combination Fig.36Further, in order to improve the connection sealing between the first connection part 71 and the beauty component 3, the beauty component 3 and / or the first connection part 71 has a first sealing convex ring 718, and the first sealing convex ring 718 has multiple settings. In the first setting method, it is only set on the beauty component 3. At this time, the first sealing convex ring 718 abuts against the first connection part 71. In the second setting method, the first sealing convex ring 718 is only set on the first connection part 71. At this time, the first sealing convex ring 718 abuts against the beauty component 3. In the third setting method, multiple groups of first sealing convex rings 718 are provided, and are respectively configured on the first connection part 71 and the beauty component 3. The above combination methods are not limited in the actual setting process. The first sealing convex ring 718 blocks the gap between the first connection part 71 and the beauty component 3, thereby improving the connection sealing between the beauty component 3 and the first connection part 71.

[0346] In this solution, the second connection part 72 is located between the beauty instrument body 1 and the negative pressure sleeve 1a, and the two opposite surfaces of the second connection part 72 are connected to the beauty instrument body 1 and the negative pressure sleeve 1a respectively. At this time, it is equivalent to forming a laminated sealing structure in the area of ​​the second connection part 72, which is more compact and can further optimize the overall sealing performance of the sealing ring 7 in the area of ​​the second connection part 72.

[0347] Furthermore, a barb section 725 is formed at the end of the second connecting portion 72 and folded toward one side, specifically, toward the inside or outside of the second connecting portion 72. In this solution, the second connecting portion 72 is folded toward the outside of the sealing ring 7. Accordingly, a hooking recess 1b1 is provided at the end face of the beauty instrument body 1. The contour of the hooking recess 1b1 is contoured with the barb section 725 so that the barb section 725 can be embedded in the hooking recess 1b1. At this time, with the mutual cooperation of the barb section 725 and the hooking recess 1b1, they can be hooked on the beauty instrument body 1, and the sealing ring 7 is more tightly connected to the beauty instrument body 1.

[0348] Further, refer to Figure 35-Figure 37 , the negative pressure sleeve 1a is detachable compared to the beauty instrument body 1. Through this arrangement, it is convenient to install the sealing ring 7. In addition, in order to improve the installation stability of the second connecting part 72, the beauty instrument body 1 also includes 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 to the shell 1b by means of threaded connection or snap connection.

[0349] At the same time, the end cover 1c has a snap-fitting protrusion 1c1 at the inner side of the housing 1b. Usually, the snap-fitting protrusion 1c1 is connected to the end cover 1c as a whole. The snap-fitting protrusion 1c1 in this solution is a sheet structure and its size is smaller than the opening size of the snap-fitting recess, so that the snap-fitting protrusion 1c1 can be embedded in the hooking recess 1b1. At this time, the snap-fitting protrusion 1c1 and the inner wall of the hooking recess 1b1 clamp the barb section 725 to fix it, and the installation stability of the second connecting portion 72 is improved, and it is not easy to loosen.

[0350] In addition, since the negative pressure sleeve 1a is detachably arranged on the beauty instrument body 1, during the disassembly process, the gap between the suction sleeve 31b and the sealing ring 7 may be relatively large, which may cause air leakage. Based on this, one side surface of the sealing ring 7 has a second sealing convex ring 726, and the second sealing convex ring 726 abuts against the suction sleeve 31b. At this time, a second sealing convex ring 726 is arranged at the sealing ring 7, and the second sealing convex ring 726 can seal the gap between the suction sleeve 31b and the sealing ring 7, thereby further optimizing the air leakage problem.

[0351] It needs to be explained that, in the two sealing implementation schemes for the negative pressure sleeve 1a and the beauty component 3 provided above, the first connecting part 71 in different implementation schemes can be interchangeably arranged, and correspondingly, the second connecting part 72 can also be interchangeably arranged. No matter what sealing structure the first connecting part 71 and the second connecting part 72 adopt, the scheme that can provide a sealing effect for the negative pressure sleeve 1a and the beauty component 3 should be included in the scope of equivalent interpretation.

[0352] [About the setting of the blowing structure]

[0353] Reference Fig.38 In order to promote the absorption of essence, while adopting the above-mentioned technical solution, an air blowing structure can also be set inside the beauty instrument. By applying airflow to the skin, it can alleviate the discomfort caused by acupuncture, light and heating during the beauty process. At the same time, it can play a certain role in massage and promote the flow of essence into the pores, thereby optimizing the beauty experience.

[0354] It can be understood that the beauty instrument in this embodiment can also include an air supply unit 14 and an air flow channel 15, which are respectively arranged on the beauty instrument body 1, and an air outlet 16 can be arranged on the beauty component 3 or the beauty instrument body 1. The air flow channel 15 can adopt a pipeline structure, such as a hose, and the air supply unit 14 can adopt an air supply air pump 142, wherein the two ends of the air flow channel 15 are respectively connected to the air outlet section of the air supply air pump 142 and the air outlet 16, and the air supply air pump 142 can generate airflow, and the air supply unit 14 sends out the airflow acting on the skin through the air flow channel 15 and the air outlet 16, so as to achieve the effect of enhancing the beauty experience.

[0355] Furthermore, the airflow channel 15 includes a first air supply branch 154 that is arranged in a straight manner, one end of the first air supply branch 154 is connected to the air supply pump 142, and the other end is connected to the air outlet 16. At this time, the straight first air supply branch 154 can minimize the energy loss during gas collision to ensure a larger wind force and meet the user experience.

[0356] The implementation principle of the first embodiment is: to provide a beauty instrument and a beauty kit that can absorb the skin with negative pressure and apply essence at the same time, so as to solve the problem of poor control of the essence application area in the prior art.

[0357] Among them, the implementation methods of the modules such as the beauty instrument body 1, the beauty head 31, the negative pressure cavity 2, the negative pressure channel 4, the negative pressure mechanism 5 and the liquid storage cavity 6 can be arbitrarily combined according to different needs without violating the laws of nature.

[0358] For example, in this embodiment, the liquid storage chamber 6 has three implementation modes: being arranged in the beauty instrument body 1, being arranged in the main body 32, and being arranged in the container 61. These three implementation modes of the liquid storage chamber 6 can be combined with any one of the multiple implementation modes of the negative pressure channel 4 to realize negative pressure adsorption of liquid.

[0359] Similarly, any implementation of other modules can also be arbitrarily combined without violating the laws of nature. No matter what combination is adopted, it should be included in the interpretation of the protection scope of this application.

[0360] To clarify the specific scheme of this embodiment, specifically, in this embodiment, first, the negative pressure channel 4 is integrated in the main body 32; secondly, the negative pressure mechanism 5 is implemented by including a negative pressure pump 51, a solenoid valve 52 and an air pressure sensor 53; furthermore, the beauty instrument body 1 is implemented by having a first avoidance port 101 and a sliding cover 13; and the beauty head 31 is connected to the main body 32 and has an adsorption sleeve 31b, a core 31a, an adsorption element 3123, an elastic member 314, and an application unit 3121 and the microneedle chip 3122, the adsorption element 3123 is arranged between the core 31a and the nano-microchip; next, the negative pressure cavity 2 adopts an implementation mode with an inner cavity part and an outer cavity part 21, and forms a tortuous airflow path; in addition, the liquid storage cavity 6 adopts an implementation mode in which the container 61 and the main body 32 can be detachably connected; finally, with regard to the optimization of the application of the essence, the implementation mode of the main body 32 driven by the vibration mechanism 9 is adopted, and the main body 32 is set as a consumable and detachably connected to the vibration connecting part 92.

[0361] By selecting the implementation methods of the above modules, a beauty kit can be realized that can promote the absorption of essence, ensure hygiene and safety, and is easy for users to use.

[0362] It is understandable that in the structural setting of this embodiment, a variety of different implementations can be obtained, as follows:

[0364] In this solution, the vibration mechanism 9 can drive the core 31a to vibrate, thereby massaging the skin. At this time, the sealing ring 7 can seal the gap between the core 31a of the beauty head 31 and the suction sleeve 31b to form a negative pressure cavity 2. The negative pressure cavity 2 is connected to the negative pressure mechanism 5 to absorb the skin. Under this condition, the skin can be accurately massaged. At the same time, by arranging an elastic deformation part 73 on the sealing ring 7, the elastic deformation part 73 can give the sealing ring 7 elastic and retractable freedom of movement. At this time, when the beauty head 31 is in a vibrating use condition, the suction sleeve 31b and the core 31a can always maintain a good sealing effect, and it is not easy to deviate when using the vibration function, and it is not easy to leak during vibration. A technical solution that can stably absorb the skin under vibration conditions is provided.

[0373] Embodiment 2:

[0374] On the basis of the first embodiment, the features not explained in the present embodiment are explained in the first embodiment and will not be described again. The difference between the present embodiment and the first embodiment lies in that the essence liquid discharge method is different, the air supply unit 14 and the air flow channel 15 are arranged differently, and the remaining structures, such as the beauty head 31, the main body 32, the vibration mechanism 9 and other parts are arranged in the same way as in the first embodiment.

[0375] Reference Fig.39 as well as Fig.40 To this end, a beauty instrument is provided for skin care, including a beauty instrument body 1, a beauty component 3 and an air supply unit 14, wherein the beauty instrument body 1 adopts the explanation of the first embodiment and is not described in detail here.

[0376] Reference Fig.41 as well as Fig.42 The beauty component 3 is arranged at one end of the beauty instrument body 1. The beauty component 3 has a connecting part 33, an inlet flow channel 1005, a liquid outlet flow channel 1004 and a liquid outlet 1002. One end of the inlet flow channel 1005 and one end of the liquid outlet flow channel 1004 are simultaneously connected to the connecting part 33. The other end of the liquid outlet flow channel 1004 is provided with a liquid outlet 1002. The liquid outlet 1002 is used for discharging liquid. The connecting part 33 is used for detachable connection with the container 61. When the container 61 is connected to the connecting part 33, the inner cavity of the container 61 is connected with the inlet flow channel 1005 and the liquid outlet flow channel 1004 through the connecting part 33.

[0377] The air supply unit 14 is disposed on the beauty instrument body 1 and is connected to the other end of the inlet air channel 1005 for generating airflow and pressing the airflow into the container 61 so that the essence in the container 61 is transferred to the liquid outlet 1002 of the beauty component 3 .

[0378] In the above scheme, the air supply unit 14 can pressurize the liquid outlet air flow into the container 61 through the liquid outlet channel 1004, so that the essence liquid flows to the liquid outlet 1002 of the beauty component 3 to realize the liquid outlet function. In this process, the pressurized liquid outlet scheme can achieve the maximum essence liquid outlet effect and reduce the residual essence liquid in the beauty instrument body 1; in addition, a container 61 structure with better anti-pollution function is adopted, and the container 61 is detachably connected to the connecting part 33, which to a certain extent avoids the possibility of dust and bacterial contamination caused by direct addition of liquid, and can realize regular replacement of the container 61 structure, which is also convenient for users to observe the inventory and condition of the essence liquid, making it more convenient and hygienic to use, and providing a healthier care environment for the skin.

[0379] Further, refer to Fig.40 In order to realize the liquid discharge function, the air supply unit 14 includes a liquid discharge air pump 141 and an air flow channel 15, wherein the liquid discharge air pump 141 is fixedly installed in the beauty instrument body 1 and is connected to the liquid discharge air pump 141 through an air flow channel 15. Specifically, in the specific setting, the air flow channel 15 adopts a pipeline structure, one end of the air flow channel 15 is connected to the liquid discharge air pump 141, and the other end is connected to the inlet air channel 1005.

[0380] At this time, the liquid outlet air pump 141 can generate an airflow, and under the guidance of the air outlet pipe, it can quickly and directly guide the airflow into the inlet flow channel 1005. After being guided by the inlet flow channel 1005, the gas can enter the container 61. At this time, the container 61 can adopt a container 61 with a higher hygiene standard such as a syringe bottle, and the container 61 has a liquid storage chamber 6 inside. After the gas enters the liquid storage chamber 6 of the container 61, the essence is guided to the liquid outlet 1002 through the liquid outlet channel 1004 to realize liquid discharge, thereby realizing the liquid discharge action.

[0381] Furthermore, at least one of the inlet flow channel 1005, the liquid outlet flow channel 1004 and the air flow channel 15 is a hose. Preferably, in this embodiment, the inlet flow channel 1005, the liquid outlet flow channel 1004 and the air flow channel 15 are all hose structures. The hose structure is conducive to adjusting the flow channel position and is easy to assemble.

[0382] Further, refer to Fig.41 In this embodiment, the beauty component 3 includes a main body 32 and a beauty head 31. In addition, in the solution shown in this embodiment, the beauty head 31 is directly connected to the main body 32 and fixedly arranged on the main body 32. At this time, the beauty head 31 and the main body 32 form an integral module structure to facilitate production and manufacturing. When the beauty head 31 is caring for the skin, the essence can be applied to the care area simultaneously, and the liquid discharge is accurate and efficient.

[0383] And, refer to Fig.42 The liquid outlet 1002 is arranged on the beauty head 31, and the connecting part 33, the inlet flow channel 1005 and the liquid outlet flow channel 1004 are arranged on the main body 32. Here, by arranging the main body 32, the connecting part 33, the inlet flow channel 1005 and the liquid outlet flow channel 1004 on the main body 32, an integrated arrangement can be achieved to reduce the manufacturing cost.

[0384] On the one hand, the main body 32 is arranged on the beauty instrument body 1. Optionally, the main body 32 can be arranged on the beauty instrument body 1 in a fixed or detachable manner. The specific arrangement method can adopt the arrangement method of the main body 32 in the first embodiment, which will not be repeated here.

[0385] It can be understood that, in another embodiment, in order to further reduce the manufacturing cost, the beauty component 3 may also only include the beauty head 31. Accordingly, the setting relationship between the various components needs to be adjusted. For example, the beauty head 31 is installed on the beauty instrument body 1, the connecting part 33 is directly set on the beauty instrument body 1, the inlet flow channel 1005 and the liquid outlet flow channel 1004 are set in the beauty instrument body 1, and the liquid outlet 1002 is set at the other end of the liquid outlet flow channel 1004. Through the above-mentioned settings, consumables and accessories can be further reduced and the manufacturing cost can be reduced.

[0386] On the other hand, the beauty head 31 may also have a variety of installation methods, such as the beauty head 31 and the main body 32 are detachably connected, or the beauty head 31 and the beauty instrument body 1 are detachably connected. The specific setting method of the beauty head 31 may be the same as that of the first embodiment, and will not be repeated here. Here, no matter whether the beauty head 31 is specifically set on the beauty instrument body 1 or the main body 32, the beauty and liquid discharge functions can be completed. Based on the above settings, the following six combination schemes are obtained, among which:

[0387] In the first combination mode, the main body 32 is not provided, and the beauty head 31 is fixedly provided on the beauty instrument body 1 .

[0388] In the second combination mode, the main body 32 is not provided, and the beauty head 31 is detachably provided on the beauty instrument body 1 .

[0389] In the third combination mode, a main body 32 is provided, and the beauty head 31 is fixedly provided on the main body 32. This embodiment adopts this arrangement mode.

[0390] In the fourth combination mode, a main body 32 is provided, and the beauty head 31 is detachably provided on the main body 32 .

[0391] In the fifth combination mode, a main body 32 is provided, and the beauty head 31 is fixedly provided on the beauty instrument body 1 .

[0392] In the sixth combination mode, a main body 32 is provided, and the beauty head 31 is detachably provided on the beauty body.

[0393] Various combinations of the above solutions should be included in the interpretation of the protection scope of this application, and the specific location of the beauty head 31 is not limited here.

[0394] In one embodiment, when the main body 32 is fixedly or detachably arranged on the beauty instrument body 1, in order to connect the airflow channel 15 with the intake airflow channel 1005, a first connecting portion 111 can be arranged on the main body 32. The first connecting portion 111 is a column tube structure. The first connecting portion 111 has a connecting channel running through both ends, and the two ends of the first connecting portion 111 extend to the inner side and the outer side of the main body 32 respectively. At this time, the end of the first connecting portion 111 protrudes outward, and the protruding area is convenient for fixed installation with the airflow channel 15 and the intake airflow channel 1005. When the connecting channel is opened, the first connecting portion 111 connects the airflow channel 15 and the intake airflow channel 1005.

[0395] Optionally, there are multiple locations for setting the liquid outlet 1002. In one embodiment, the liquid outlet 1002 is set at the beauty component 3, and the essence flows to the beauty component 3 under the transfer of the liquid outlet channel 1004 and is discharged from the liquid outlet 1002; in another embodiment, the liquid can be discharged from other parts by changing the flow direction of the liquid outlet channel 1004. For example, a part of the liquid outlet channel 1004 is set on the beauty instrument body 1, and the liquid outlet 1002 is opened at the end face of the beauty instrument body 1. At this time, the essence passes through the liquid outlet channel 1004 and is discharged from the beauty instrument body 1. The above method can also achieve the liquid discharge effect. Combined with the above combination methods, sixteen liquid discharge combinations can be formed, which are not listed here one by one. In this embodiment, the liquid outlet 1002 is set on the beauty head 31 of the beauty component 3.

[0396] Optional, see Fig.43 The connecting portion 33 includes a columnar or conical plug-in portion 330, and the plug-in portion 330 is connected by being inserted into a vial. The plug-in angle of the vial can be set to multiple groups. At this time, the plane where the liquid outlet 1002 is located is used as a reference. The angle formed by the extension direction of the plug-in portion 330 and the plane where the liquid outlet 1002 is located is between degrees and degrees. At this time, a plug-in angle perpendicular to the vibration direction to parallel to the vibration direction can be obtained. This setting method is the same as that of Example 1 and will not be repeated here. In this embodiment, the angle formed by the extension direction of the plug-in portion 330 and the plane where the liquid outlet 1002 is located is degrees.

[0397] Further, refer to Fig.43 Combined with Fig.13 The connecting portion 33 also includes a positioning recess 333 (equivalent to the bottle mouth slot 339), the positioning recess 333 has a bottom wall and a side wall connected to the bottom wall, the plug-in portion 330 is arranged on the bottom wall, and the side wall is provided with a limiting portion, which is used to abut and limit the surrounding side of the container 61 when the container 61 is connected to the plug-in portion 330. In this embodiment, the positioning recess 333 is arranged on the main body 32, and the above-mentioned setting method is the same as that in embodiment 1, and will not be repeated here.

[0398] Furthermore, the main body 32 is located inside the beauty instrument body 1. Such an arrangement can make the structure more compact, and a first avoidance opening 101 is opened on one side of the beauty instrument body 1. The first avoidance opening 101 is used to expose the connection portion 33 for disassembly and assembly of the container 61. The above arrangement is the same as that in Example 1 and will not be repeated here.

[0399] Optionally, the liquid storage chamber 6 can be set up in the same manner as in Example 1, where the liquid storage chamber 6 is directly set in the main body 32. In this way, the connecting portion 33 structure can be removed, and it is only necessary to connect one end of the inlet flow channel 1005 to the liquid storage chamber 6 and connect one end of the outlet flow channel 1004 to the liquid storage chamber 6 to form a liquid outlet circuit. At the same time, a transparent window can be provided to observe the remaining liquid in the liquid storage chamber 6. The specific setting method can be based on Example 1 and will not be repeated here.

[0400] Optionally, continue to refer to Fig.43 When the main body 32 is detachable compared to the beauty instrument body 1, the beauty instrument body 1 has an installation opening 102 for the main body 32 to be disassembled and assembled. By respectively opening the first avoidance opening 101 and the installation opening 102 on the beauty instrument body 1, the main body 32 and the container 61 can also be installed inside the beauty instrument body 1, thereby further optimizing the compactness of the beauty instrument structure.

[0401] Further, refer to Fig.32 A one-way valve 1008 is provided in the liquid outlet channel 1004. Specifically, the one-way valve 1008 adopts a spring 3141 ball valve structure. By installing the one-way valve 1008 to the liquid outlet channel 1004, it can prevent the essence from flowing back in the liquid outlet pipe, thereby reducing the possibility of contamination of the essence in the bottle, optimizing the directional consistency of the essence when it is discharged, and making the use environment more hygienic and clean.

[0402] In another embodiment, reference Fig.28 The one-way valve 1008 can also be arranged inside the beauty head 31. The one-way valve 1008 can block the liquid outlet 1002 and also have the effect of preventing backflow.

[0403] Reference Fig.42 When the air supply unit 14 is used to discharge the essence, a vibration mechanism 9 connected to the beauty component 3 can also be arranged inside the beauty instrument.

[0404] Because the beauty component 3 has multiple configurations, the beauty component 3 and the vibration mechanism 9 also have multiple configurations. In one embodiment, when the beauty component 3 only includes the beauty head 31, the vibration mechanism 9 includes a vibration motor 91, which is installed inside the beauty instrument body 1. At this time, the vibration motor 91 can be directly connected to the beauty head 31 to drive the beauty head 31 to reciprocate. Through the above configuration, the beauty head 31 can be driven to vibrate and massage the skin, thereby improving the care experience.

[0405] Combination Fig.23 In this embodiment, the beauty component 3 includes a beauty head 31 and a main body 32, the connection part 33, the inlet flow channel 1005 and the liquid outlet flow channel 1004 are arranged on the main body 32, the beauty head 31 is connected to one end of the main body 32, the vibration motor 91 is connected to the other end of the main body 32, and the vibration motor 91 drives the main body 32 to drive the beauty head 31 to reciprocate. Compared with the solution of only setting the beauty head 31, by adding the main body 32, the beauty component 3 can be modularly designed, which is convenient for production and assembly, and the connection part 33, the inlet flow channel 1005 and the liquid outlet flow channel 1004 and other components can be integrated, and the overall structure is compact, and the specific setting method is not repeated.

[0406] Furthermore, in order to realize the connection between the vibration motor 91 and the beauty head 31 or the main body 32, the vibration mechanism 9 also includes a vibration connector 92, which is transmission-connected to the vibration motor 91. The specific structure of the vibration connector 92 is the same as that of the first embodiment and will not be described herein.

[0407] In addition, because the main body 32 integrates various components, the main body 32 can be detachably connected to the vibration connection member 92. Based on this, the vibration connection member 92 is provided with a second avoidance opening 921 that runs through both inner and outer sides. The second avoidance opening 921 is used to expose the connection portion 33 for the container 61 to be disassembled and assembled. The vibration motor 91 is used to drive the vibration connection member 92 to reciprocate. Through the above arrangement, the beauty component 3 can be disassembled and replaced, which is convenient, safe and hygienic to use. The specific detachable manner can be based on the relevant arrangement of the first embodiment, combined with Fig.24 For example, an elastic fastener 922 is provided on the vibration connector 92, and a fastening portion 923 movably fastened to the elastic fastener 922 is provided on the main body 32. The positions of the elastic fastener 922 and the fastening portion 923 can be interchanged, and the specific setting method is not described in detail here.

[0408] Further, refer to Fig.39 as well as Fig.40In this embodiment, the vibration mechanism 9 can also be arranged in the beauty instrument body 1 to further optimize the compactness of the structure. First, it is necessary to open an installation opening 102 for disassembling and assembling the main body 32 at one end of the beauty instrument body 1, and set a first avoidance opening 101 on the beauty instrument body 1 corresponding to the second avoidance opening 921. At this time, the container 61 can be assembled into the connecting portion 33 through the first avoidance opening 101 and the second avoidance opening 921. The setting method of the first avoidance opening 101 and the second avoidance opening 921 is the same as that of the first embodiment.

[0409] It should be noted that, refer to Fig.41 When the main body 32 is disassembled and assembled, the intake air duct 1005 and the air duct 15 need to be disconnected from each other. In order to make the air path accurately conductive, when the intake air duct 1005 is set on the main body 32, a second connecting portion 112 is provided on the vibration connecting member 92. The structure of the second connecting portion 112 is similar to the structure of the connecting portion 11 in the first embodiment. It is also set as a column tube structure, and a connecting channel is set in the column tube structure. Correspondingly, when the corresponding first connecting portion 111 is set at the main body 32, it is necessary to set the first connecting portion 111 as a recessed structure for the second connecting portion 112 to be inserted and positioned at one end close to the inner side of the vibration connecting member 92. At this time, the air supply unit 14 is connected to the intake air duct 1005 via the second connecting portion 112. The specific setting method is not repeated in this embodiment.

[0410] Under the action of the second connecting portion 112, the beauty component 3 can be detachably connected to the air supply unit 14 and the liquid outlet channel 1004, providing a precise switching effect. The beauty component 3 can maintain the connection of the air path when it is replaced multiple times, overcoming the technical obstacle that it is difficult to achieve stable air flow in the beauty component 3 when it is disassembled.

[0411] It is understandable that the specific structures of the first connecting portion 111 and the second connecting portion 112 can be interchanged as long as they can satisfy the plug-in connection.

[0412] Further, refer to Fig.40 Combined with Fig.21 On the basis of the foregoing of this embodiment, a negative pressure mechanism 5 can be further provided on the beauty instrument to obtain a negative pressure adsorption function. At this time, a beauty instrument is obtained, including a beauty instrument body 1, a beauty head 31, an air supply unit 14 and a negative pressure mechanism 5, wherein the beauty head 31 is arranged at one end of the beauty instrument body 1, and the beauty head 31 is provided with a negative pressure cavity 2 connected to the outside, the beauty head 31 includes an adsorption element 3123 located in the negative pressure cavity 2, the adsorption element 3123 has a porous structure, and is used to retain essence, the setting method of the negative pressure cavity 2 and the setting method of the adsorption element 3123 are consistent with those in the first embodiment, and are not described in detail here.

[0413] As shown in the above structure, the air supply unit 14 is used to communicate with the liquid storage chamber 6 through an inlet flow channel 1005, and the liquid storage chamber 6 is connected to the adsorption element 3123 through an outlet flow channel 1004. The air supply unit 14 presses the air flow into the liquid storage chamber 6 through the outlet flow channel 1004, and allows the essence to be drawn from the liquid storage chamber 6 to the adsorption element 3123 and applied to the skin.

[0414] The key point is that the negative pressure mechanism 5 is connected to the negative pressure cavity 2, and the negative pressure mechanism 5 is used to extract air so that a negative pressure area that adsorbs the skin is formed in the negative pressure cavity 2.

[0415] Continue to refer to Fig.40 Specifically, in this embodiment, the negative pressure mechanism 5 includes a negative pressure pump 51 and a solenoid valve 52. The negative pressure pump 51 is fixedly installed in the beauty instrument body 1, and the negative pressure pump 51 is connected to the negative pressure cavity 2 through a negative pressure channel 4. In this embodiment, the negative pressure channel 4 is arranged in the main body 32 and has a tubular structure, preferably a hard pipe, which is not easy to deform and can perform negative suction more smoothly.

[0416] Among them, one end of the negative pressure channel 4 is connected to the main body 32 and opens on the main body 32. At the same time, the end of the negative pressure channel 4 that opens on the main body 32 is connected to the negative pressure mechanism 5. Furthermore, the other end of the negative pressure channel 4 is connected to the beauty head 31. Correspondingly, through holes that are respectively connected to the negative pressure channel 4 and the negative pressure cavity 2 can be penetrated on the beauty head 31. At this time, the negative pressure pump 51 can suck the air in the negative pressure cavity 2 through the negative pressure pipe.

[0417] Furthermore, the solenoid valve 52 is connected to the negative pressure channel 4 at the same time. In the specific setting, a multi-way valve 54 structure as in Example 1 can be used between the negative pressure pump 51 and the solenoid valve 52, and an integrated pipeline is set on the multi-way valve 54. By connecting the integrated pipeline with the negative pressure channel 4, the air path is connected, which will not be elaborated here.

[0418] Furthermore, in this embodiment, the air supply unit 14 can also play the role of blowing air to the skin in the first embodiment, but when setting, it mainly includes two air supply schemes, one of which is to use a single air pump to achieve the air supply effect. Under this scheme, a single air pump element can be used to achieve the liquid discharge and blowing functions, and the other is to achieve the air supply effect through a dual air pump. Under this scheme, two different air pumps can be used to perform the liquid discharge and blowing functions respectively.

[0419] Among them, refer to Fig.40 as well as Fig.44 In the single air pump solution, based on the above components, for ease of description, the air flow channel 15 is divided into three parts, namely a first air flow channel 151, a second air flow channel 152 and a third air flow channel 153.

[0420] At this time, a beauty instrument can be obtained, including a beauty instrument body 1, one end of which is provided with a beauty head 31, and also including an air supply unit 14 and a first air flow channel 151. The air supply unit 14 is arranged inside the beauty instrument body 1, and one end of the beauty instrument body 1 is provided with an air outlet 16 adjacent to the beauty head 31. The first air flow channel 151 connects the air supply unit 14 and the air outlet 16. The air supply unit 14 sends out airflow to act on the skin through the first air flow channel 151 and the air outlet 16.

[0421] At this time, the air supply unit 14 can generate airflow by pressing the airflow into the airflow channel 15. Under the guidance of the airflow channel 15, the airflow is blown out from the air outlet 16 and acts on the skin. At this time, pressure can be applied to the essence on the skin to accelerate its penetration into the pores. The absorption effect of the essence is significantly improved, and blowing can speed up the airflow on the skin surface and relieve skin discomfort.

[0422] Furthermore, it also includes a liquid outlet channel 1004 and a second air flow channel 152. The beauty head 31 has a liquid outlet 1002. The liquid outlet channel 1004 is used to connect the liquid outlet 1002 with a liquid storage chamber 6. The specific connection method adopts the connection method between the liquid outlet air pump 141 and the inlet channel 1005 in the previous text, and this part of the setting is not repeated here; furthermore, the second air flow channel 152 is used to connect the air supply unit 14 with the liquid storage chamber 6. In this embodiment, the liquid storage chamber 6 is connected to the second air flow channel 152 through the inlet channel 1005, and the connection method is also not repeated here. In this scheme, the air supply unit 14 adopts a single air pump, and the air supply unit 14 is respectively connected to the first air flow channel 151 and the second air flow channel 152.

[0423] Under the above setting, the air supply unit 14 presses gas into the liquid storage chamber 6 through the second air flow channel 152, so that the essence flows out through the liquid outlet channel 1004 and the liquid outlet 1002, thereby realizing the use of the same power source to complete the two functional actions of liquid discharge and blowing, and the functions of the beauty instrument are integrated.

[0424] 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 set. Therefore, in the single air pump solution, the air supply unit 14 includes an air supply pump 142, which can be regarded as a replacement for the liquid outlet air pump 141 mentioned above, or only the liquid outlet air pump 141 can also achieve the air outlet effect. When connecting, first connect one end of the third air flow channel 153 to the output end of the air supply pump 142, and the other end to the first air flow channel 151 and the second air flow channel 152, respectively. Here, the third air flow channel 153, the first air flow channel 151 and the second air flow channel form a tree-like airway structure, which can achieve the gas diversion effect.

[0425] It should be explained that the third air flow channel 153 , the first air flow channel 151 and the second air flow channel 152 may be connected at different points at the same time, or may be connected at the same point at the same time.

[0426] Furthermore, in order to optimize the airflow effect, the beauty instrument also includes a switching valve 143, wherein the switching valve 143 has a multi-channel structure, and the third airflow channel 153, the first airflow channel 151 and the second airflow channel 152 are fixedly connected to the switching valve 143 at the same time. The switching valve 143 can switch the airflow so that the airflow flows from the third airflow channel 153 to the first airflow channel 151 or the second airflow channel 152 alone.

[0427] Under this effect, the airflow can be controllably adjusted. By directing the airflow to one of the paths alone, it can be guaranteed to have a good airflow velocity, making the function more flexible and stable.

[0428] Furthermore, 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 this embodiment, all three are hose structures, wherein the hose structure facilitates wiring and layout, and can also bypass other components to avoid interference.

[0429] Furthermore, in the specific setting, if there are curved parts in the first airflow channel 151, the second airflow channel 152 and the third airflow channel 153, it will cause kinetic energy loss when the gas is discharged, and the strength of the discharge. At this time, in order to ensure the discharge effect, at least one of the first airflow channel 151, the second airflow channel 152 and the third airflow channel 153 is set in a straight shape. Under the setting of the above structure, the straight structure can minimize the collision loss lost during the flow of the airflow, so that the airflow can maintain a large flow rate. Preferably, in this embodiment, the first airflow channel 151 and the third airflow channel 153 are set in a straight shape.

[0430] Through the above-mentioned structural setting, the first air flow channel 151 and the third air flow channel 153 form a first air supply branch 154 for providing air flow to the air outlet 16, and the second air flow channel 152 and the third air flow channel 153 form a second air supply branch 155 for providing air flow to the liquid storage chamber 6.

[0431] Among them, in actual application, it is found that the air flow intensity at the air outlet 16 is required to be relatively large, otherwise the user's feeling when blowing will be weak. Based on this, preferably, the first air supply branch 154 maintains a straight structure as a whole. When setting, it is only necessary to set the first air flow channel 151 and the third air flow channel 153 coaxially. Such a setting can avoid air flow loss in the first air supply branch 154 as much as possible.

[0432] However, often in the beauty instrument body 1, due to space limitations, the first air supply branch 154 will inevitably interfere with other components. In order to ensure that its air outlet 16 has a good air outlet intensity, an avoidance bend portion can be provided on the first air supply branch 154. The avoidance bend portion accounts for no more than 20% of the total length of the first air supply branch 154. In this way, excessive loss of air flow can be avoided as much as possible to ensure the blowing effect.

[0433] Correspondingly, if the liquid discharge effect is insufficient in products of different models, the second air supply branch 155 can be made straight by adjusting the position of the air supply pump 142, and an avoidance bend can be set in the second air supply branch 155. Accordingly, the avoidance bend accounts for no more than 20% of the total length of the first air supply branch 154 to ensure sufficient airflow intensity when discharging liquid.

[0434] It is understandable that the setting position of the air outlet 16 is adjusted according to actual needs. For example, it can be set on the beauty instrument body 1, and the air outlet 16 is set adjacent to the beauty head 31, or the air outlet 16 can be directly set on the beauty head 31 to achieve the blowing function while beauty treatment. In addition, this solution can be synchronously set in combination with the vibration mechanism 9, for example, the beauty head 31 is connected to the vibration mechanism 9, and the vibration mechanism 9 is used to drive the beauty head 31 to vibrate reciprocally to achieve a massage effect.

[0435] Reference Fig.41 and Fig.45 In the dual air pump solution, based on the foregoing, the following solution can be obtained: a beauty instrument, comprising a beauty instrument body 1, a beauty component 3, an air supply unit 14 and an air flow channel 15, wherein the beauty component 3 has an inlet flow channel 1005, a liquid outlet flow channel 1004 and a liquid outlet 1002, one end of the liquid outlet flow channel 1004 is connected to the liquid outlet 1002, and the other end is used to connect to the liquid storage chamber 6, the beauty component 3 also includes a microneedle chip 3122, and the microneedle chip 3122 is used to puncture the skin.

[0436] The air supply unit 14 is disposed inside the beauty instrument body 1. One end of the inlet channel 1005 is connected to the air supply unit 14, and the other end is used to connect to the liquid storage chamber 6. The air supply unit 14 transfers the essence in the liquid storage chamber 6 to the liquid outlet 1002 through the inlet channel 1005 and the liquid outlet channel 1004.

[0437] Furthermore, an air outlet 16 is provided on the beauty component 3 or the beauty instrument body 1 , and the air flow channel 15 is connected to the air supply unit 14 and the air outlet 16 , and the air supply unit 14 sends out airflow to act on the skin through the air flow channel 15 and the air outlet 16 .

[0438] The difference from a single air pump is that the air supply unit 14 includes an air supply air pump 142 and a liquid outlet air pump 141, wherein the first air flow channel 151 independently forms a first air supply branch 154, and the second air flow channel 152 independently forms a second air supply branch 155. At this time, it can also be understood that the air flow channel 15 includes a first air supply branch 154 and a second air supply branch 155.

[0439] During setting, one end of the first air supply branch 154 is connected to the air supply pump 142 and the other end is connected to the air outlet 16 , and one end of the second air supply branch 155 is connected to the liquid outlet air pump 141 and the other end is connected to the inlet air duct 1005 .

[0440] At this time, it is equivalent to forming two independent air paths, and performing liquid discharge and air blowing actions respectively. Compared with the single air pump solution, the dual air pump solution has a larger single-path air volume.

[0441] It should be explained that, regardless of whether a single air pump solution or a dual air pump solution is provided, the configuration of the beauty component 3 can be consistent with the configuration in Embodiment 1, and different combinations of the air supply unit 14 and the air flow channel 15 can be applied to the component combinations described above, which will not be elaborated here.

[0442] The implementation principle of the second embodiment is: by adopting the press-in liquid discharge method, the essence in the container 61 can be fully discharged, further reducing the residue of the essence, and the skin care environment is more hygienic. In addition, by changing the number of air pumps of the air supply unit 14, a single-pump air supply and a double-pump air supply solution can be achieved, which can flexibly meet the design requirements of the structure and has a flexible structure.

[0443] Furthermore, based on the combination of the second embodiment and the first embodiment, a variety of different types of beauty instrument solutions can be obtained.

[0444] One: A beauty instrument, comprising a beauty instrument body 1, and also comprising: a beauty head 31, which is arranged at one end of the beauty instrument body 1 and is provided with a negative pressure cavity 2 connected to the outside, the beauty head 31 includes an adsorption element 3123 located in the negative pressure cavity 2, and the adsorption element 3123 has a porous structure and is used to retain essence; an air supply unit 14, which is used to communicate with a liquid storage cavity 6 through an inlet flow channel 1005, and the liquid storage cavity 6 is connected to the adsorption element 3123 through an outlet flow channel 1004, the air supply unit 14 presses the air flow into the liquid storage cavity 6 through the outlet flow channel 1004, and causes the essence to be pumped from the liquid storage cavity 6 to the adsorption element 3123 and applied to the skin; and a negative pressure mechanism 5, which is connected to the negative pressure cavity 2 and is used to extract air so that a negative pressure area for adsorbing the skin is formed in the negative pressure cavity 2.

[0445] In this scheme, the negative pressure mechanism 5 can be started to extract the air in the negative pressure cavity 2 to form a negative pressure area that can adsorb the skin, thereby adsorbing the skin and positioning it. Under this condition, the beauty instrument is not easy to deviate; at the same time, the liquid storage cavity 6 can be used to store the essence, and then, driven by the air supply unit 14 and guided by the inlet flow channel 1005, the air flow is pressed into the liquid storage cavity 6, so that the essence is pressed out and transferred to the liquid outlet 1002 through the liquid outlet flow channel 1004, so as to achieve the liquid discharge effect; at this time, the adsorption element 3123 adsorbs the essence to prevent the essence from flowing back into the negative pressure mechanism 5, so that the essence is accurately applied to the adsorbed skin to prevent the essence from splashing into the eyes or nostrils, and the problem of inaccurate coating area of ​​the beauty instrument when applying the essence is solved, and the coating effect of the essence on the skin is optimized and improved.

[0446] Second: A beauty instrument, comprising a beauty instrument body 1, one end of which is provided with a beauty head 31, and further comprising: an air supply unit 14, which is provided on the beauty instrument body 1; a first air flow channel 151, one end of the beauty instrument body 1 is provided with an air outlet 16 adjacent to the beauty head 31, the first air flow channel 151 connects the air supply unit 14 and the air outlet 16, and the air supply unit 14 sends out airflow to act on the skin through the first air flow channel 151 and the air outlet 16.

[0447] In this solution, the air supply unit 14 can generate airflow by pressing the airflow into the airflow channel 15. Under the guidance of the airflow channel 15, the airflow is blown out from the air outlet 16 and acts on the skin. At this time, pressure can be applied to the essence on the skin to accelerate its penetration into the pores. The absorption effect of the essence is significantly improved, and blowing can speed up the airflow on the skin surface and relieve skin discomfort. It is suitable for different skin care scenarios such as phototherapy, electrotherapy and heat therapy.

[0448] Third: A beauty instrument, comprising a beauty instrument body 1, and a beauty component 3, having an inlet flow channel 1005, a liquid outlet flow channel 1004, and a liquid outlet 1002, one end of the liquid outlet flow channel 1004 is connected to the liquid outlet 1002, and the other end is used to connect to the liquid storage chamber 6, the beauty component 3 also includes a microneedle chip 3122; an air supply unit 14, which is arranged on the beauty instrument body 1, one end of the inlet flow channel 1005 is connected to the air supply unit 14, and the other end is used to connect to the storage chamber The beauty instrument body 1 is connected to the liquid chamber 6, the air supply unit 14 transfers the essence in the liquid storage chamber 6 to the liquid outlet 1002 through the inlet flow channel 1005 and the liquid outlet flow channel 1004; and the air flow channel 15, the beauty component 3 or the beauty instrument body 1 is provided with an air outlet 16, the air flow channel 15 connects the air supply unit 14 and the air outlet 16, and the air supply unit 14 sends out the air flow acting on the skin through the air flow channel 15 and the air outlet 16.

[0449] In this solution, firstly, the air supply unit 14 can pressurize the essence to the liquid outlet 1002 through the air inlet channel and the liquid outlet channel, and then the essence is applied to the skin surface through the beauty component 3 to achieve the liquid outlet function; at the same time, the microneedle chip 3122 on the beauty component 3 can pierce the skin, and during the piercing action, part of the essence is driven to the deep skin to achieve beauty care, and more importantly, under the action of the air flow channel 15 and the air outlet 16, other essence can be blown into the punctured holes in the skin, so that more essence enters the deep skin, which promotes the absorption of the essence, and also has the effect of massaging the skin and relieving discomfort at the acupuncture site.

[0450] Embodiment three:

[0451] Reference Fig.45 According to the skin care needs of different users, the skin care function of the beauty instrument can be adjusted. Based on this, the beauty instrument also includes a care component 12. It can be understood that the care component 12 in this embodiment can be combined into any beauty instrument in Example 1 or Example 2. Specifically, the care component 12 includes a light source care module, an electrode care module, and a heating care module.

[0452] First of all, the light source care module adopts LED light-rejuvenation module, which realizes intense pulsed light skin care by emitting light in the spectrum range of 410nm-1200nm. The photochemical reaction produced when the light acts on the skin promotes the rearrangement and regeneration of the molecular structure of the collagen fibers and elastic fibers in the dermis, making the skin firm and smooth; at the same time, the photothermal effect it produces can enhance blood vessel function, improve circulation, and promote collagen regeneration, thereby achieving the effect of eliminating wrinkles and shrinking pores.

[0453] Furthermore, the electrode care module mainly includes an electrode head for generating microcurrent, which can stimulate the rapid proliferation of subcutaneous collagen by applying microcurrent to the skin surface, improve the symptoms of skin wrinkles, and make the skin gradually smooth and firm.

[0454] In addition, the heating care module mainly includes an electric heating plate structure, which generates heat through the electric heating plate. When the beauty instrument is close to the skin, the heat is transmitted to the skin, causing the pores to open slightly to better absorb the essence, thereby optimizing the care effect.

[0455] Here, the aforementioned care modules can be installed on the beauty instrument according to actual needs, and at least one of the light source care module, the electrode care module and the heating care module is arranged on the beauty instrument. No specific restrictions are imposed on the specific selection of each care module. It can be understood that the care component 12 can be separately configured on the beauty instrument body 1 or the beauty head 31 when it is specifically arranged. The specific arrangement method can be adjusted according to the actual situation. There are two general situations:

[0456] First: when a single care module needs to be installed, for example, when an electrode care module needs to be set on the beauty instrument, the electrode care module can be installed to one end of the beauty instrument body 1 close to the beauty head 31, or the electrode care module can be directly installed on the beauty head 31.

[0457] Second: when multiple care modules need to be installed, for example, when an electrode care module and a heating care module need to be set on the beauty instrument, the electrode care module can be set on the beauty instrument body 1, and the heating care module can be set on the beauty head 31, or both can be set on the beauty instrument body 1 at the same time, or both can be set on the beauty head 31 at the same time; it can be understood that the embodiments of the present application do not limit the specific number and specific setting position of each care module, different types of care modules and different installation positions can be arbitrarily combined, and no matter how many care modules are selected, and no matter what specific installation position is selected, the final and actual specific combination method should be included in the protection scope of the present application, and no specific restrictions are made here.

[0458] The implementation principle of the third embodiment is: by setting different types of care components 12, different skin care needs of different users can be adapted.

[0459] So far, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
