[0034] 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 making creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should 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 located component. 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 located component.

[0036] In addition, the terms "long", "short", "inside", "outside", etc. that indicate orientation or positional relationships are based on the orientation 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 orientation or operate in a specific orientation structure, and should not be understood as a limitation of the present invention.

[0037] The following is combined with Figure 1-5 The technical solution of the utility model is further illustrated through specific implementation methods.

[0038] Reference Figure 1 、 Figure 2 as well as Figure 3 This embodiment provides a beauty instrument, which mainly includes a beauty instrument body 1, a core 31a, a suction sleeve 31b, a sealing ring 7, a vibration mechanism 9, and a negative pressure mechanism 5. The core 31a, the suction sleeve 31b, and the sealing ring 7 form a beauty head 31 for skin care. The beauty instrument body 1 provides a mounting location for various components, and the vibration mechanism 9 and the negative pressure mechanism 5 are respectively disposed within the beauty instrument body 1.

[0039] Specifically, the core 31a is connected to the vibration mechanism 9. Usually, the vibration mechanism 9 mainly includes a vibration motor 91 and a vibration connector 92. The core 31a is installed on the vibration connector 92. At this time, under the drive of the vibration motor 91, the vibration mechanism 9 can drive the core 31a to vibrate back and forth to achieve the effect of vibration massage.

[0040] At the same time, the core 31a is arranged in the adsorption sleeve 31b. In order to realize the adsorption function, a negative pressure channel 4 for gas transmission is provided inside the core 31a, and the negative pressure channel 4 usually adopts a pipeline structure; at this time, a negative pressure cavity 2 connected to the negative pressure channel 4 is formed between the core 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 pressure channel 4; through the above arrangement, the airflow can flow into the negative pressure mechanism 5 through the negative pressure channel 4, thereby forming a negative pressure area in the negative pressure cavity 2 that can adsorb the skin.

[0041] It can be understood that the negative pressure mechanism 5 mainly includes a negative pressure pump and a solenoid valve. By connecting the negative pressure pump and the solenoid valve to the negative pressure channel 4 at the same time, the air extraction effect can be achieved.

[0042] Furthermore, in this embodiment, the sealing ring 7 is located between the core body 31a and the adsorption sleeve 31b, and the sealing ring 7 is connected to the core body 31a and the adsorption sleeve 31b respectively, 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. Moreover, the sealing ring 7 has an elastic deformation part 73, and the elastic deformation part 73 is used to provide elastic buffering for the core body 31a and the adsorption sleeve 31b.

[0043] In the above scheme, the vibration mechanism 9 can drive the core 31a to vibrate, thereby massaging the skin. At this time, the negative pressure mechanism 5 can adsorb the skin and adsorb the skin through the negative pressure cavity 2. 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 elastic freedom of movement. At this time, when the beauty head 31 is in the vibrating use condition, the adsorption 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, providing a better experience.

[0044] 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 generally 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, due to the limited softness of the skin, 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.

[0045] Specifically, in one embodiment, the elastic deformation part 73 can be formed of a soft elastic material, for example, the elastic deformation part 73 can be set to a silicone or rubber structure. At this time, the elastic deformation part 73 has an elastic expansion effect, which can provide sealing and elastic buffering functions to meet the working conditions.

[0046] 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, the adsorption sleeve 31b will be applied with a vertical displacement perpendicular to the axis of vibration. At this time, the structure of the elastic deformation part 73 adopts a conventional straight cylinder structure, which may cause lateral deformation and thus lead to air leakage.

[0047] Reference Figure 4 In one embodiment, in order to overcome the above-mentioned technical obstacles, in this 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 driving force 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.

[0048] It is understood that the corrugated segments 731 can be arranged in a plurality of adjacent combinations during actual configuration. A single corrugated segment 731 can be bent inward or outward, and the specific bending direction can be adjusted according to actual needs. In this embodiment, an inward bending method is used for demonstration. The inward bending method facilitates the assembly of the sealing ring 7 in a narrow space. In addition, in another embodiment, the corrugated segment 731 can also be replaced with other similar structures, such as a serrated structure. Any structure that can achieve telescopic buffering can be tried and should be included in the scope of protection of this application.

[0049] Furthermore, in this embodiment, combined with Figure 3 and Figure 5 In order to optimize the elastic deformation portion 73's resistance to deformation perpendicular to the vibration direction, the elastic deformation portion 73 further includes a reinforcement section 732. 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 portion 73 to form a first step surface 733 and a second step surface 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.

[0050] It can be understood that the number of reinforcement segments 732 can be multiple groups, and different reinforcement segments 732 can be selectively set in the elastic deformation part 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 segment 732 is recessed toward the inside.

[0051] In addition, refer to Figure 3 and Figure 5 The thickness of 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.

[0052] In order to optimize the overall sealing performance of the sealing ring 7 , the connection stability between the sealing ring 7 and the core 31 a and the adsorption sleeve 31 b is also an important influencing factor.

[0053] To this end, continue to refer to Figure 3 and Figure 5The 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 that is 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 can be obtained with good sealing.

[0054] Furthermore, on the basis of setting the first fitting section 711, the first connecting part 71 also includes a first extension section 712 connected to the first fitting section 711, and the first extension section 712 extends and covers and is fixed on the end face of the core body 31a. At this time, the first extension section 712 can further increase the wrapping property, thereby further optimizing the sealing property of the first connecting part 71.

[0055] In addition, refer to Figure 5 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 this embodiment, the second connecting portion 72 is attached to the outer circumference of the adsorption sleeve 31b.

[0056] 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, thereby achieving mutual connection between the two. Such a setting can have a larger contact area, thereby obtaining a better sealing effect.

[0057] 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, it also includes the main body 32, which 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 this 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 part 71 is located between the main body 32 and the core body 31a, and the opposite side surfaces of the first connecting part 71 are respectively connected to the main body 32 and the core body 31a. At this time, it is equivalent to clamping the first connecting part 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.

[0058] 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 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 seal 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.

[0059] 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 can be 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.

[0060] Further, continue to refer to Figure 5 A second sealing protrusion 722 is provided on the second connecting portion 72 and the adsorption sleeve 31b. The setting method of the second sealing protrusion 722 is similar to that of the first sealing protrusion 713 and is not repeated here. It can be understood that a second sealing protrusion 722 is provided on the adsorption sleeve 31b and / or the second connecting portion 72. The second sealing protrusion 722 can block the gap between the second connecting portion 72 and the adsorption sleeve 31b to increase the sealing between the core 31a and the second connecting portion 72.

[0061] In summary, the beauty instrument provided in this embodiment has the following advantages:

[0062] ① Provides a beauty instrument solution that can achieve vibration massage under negative pressure adsorption conditions, so that the core 31a is not easily offset during massage and the massage accuracy is good.

[0063] ② A sealing ring 7 structure is provided to ensure stable sealing under vibration conditions, solving the problem of easy air leakage under adsorption massage conditions.

[0064] 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 they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
