[0053] 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.

[0054] 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.

[0055] 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.

[0056] The following is combined with Figure 1-7 The technical solution of the utility model is further illustrated through specific implementation methods.

[0057] Example 1:

[0058] Reference Figure 1 and Figure 2This embodiment provides a beauty instrument, comprising a beauty instrument body 1, a vibration mechanism 9, a beauty component 3, and a sealing ring 7. 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. Furthermore, 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 is used to drive the beauty component 3 to vibrate back and forth. Typically, the beauty component 3 is arranged parallel to the length of the beauty instrument, and the vibration mechanism 9 is used to drive the beauty component 3 to vibrate back and forth along the length of the beauty instrument, which is defined herein as the vibration direction of the beauty component 3.

[0059] Furthermore, the beauty component 3 is used to beautify the skin, such as microneedle skin care, photon skin care or electrotherapy skin care, and the specific structure of the beauty component 3 is not limited here; at this time, the negative pressure sleeve 1a is sleeved on the outside of the beauty, and the beauty component 3 is located inside the negative pressure sleeve 1a.

[0060] Typically, the vibration mechanism 9 mainly includes a vibration motor and a vibration connector, and the beauty component 3 is mounted on the vibration connector. At this time, driven by the vibration motor, the vibration mechanism 9 can drive the beauty component 3 to vibrate back and forth to achieve a vibration massage effect.

[0061] 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 position state is that the end face of the beauty component 3 is flush with the opening; the third position state is that the beauty component 3 slightly exceeds the opening of the beauty component 3; in the above three positional relationships, the negative pressure sleeve 1a can be more stably sucked against the skin.

[0062] Further, combined with Figure 3 The sealing ring 7 can be made of an elastic material such as silicone or rubber, and the specific material is not limited here; furthermore, the sealing ring 7 includes a first connecting portion 71, an elastic deformation portion 73 and a second connecting portion 72 connected in sequence along the vibration direction. Preferably, the first connecting portion 71, the elastic deformation portion 73 and the second connecting portion 72 are connected as one body, so as to ensure that the sealing ring 7 has good sealing performance.

[0063] Further, refer to Figure 2 and Figure 3 The first connecting part 71 is connected to the beauty component 3, and the second connecting 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 a seal 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, and the beauty instrument adsorbs the skin through the negative pressure cavity 2.

[0064] Specifically, to achieve the suction function, the negative pressure chamber 2 can be connected to an external negative pressure mechanism (not shown). In this embodiment, the negative pressure mechanism is located within the beauty instrument body 1 and is used to draw air from the negative pressure chamber 2. The negative pressure mechanism primarily comprises a negative pressure pump and a solenoid valve, which are connected to the negative pressure chamber 2 via a negative pressure channel. The negative pressure channel can be constructed as a pipeline. By activating the negative pressure pump and solenoid valve, a negative pressure region can be formed within the negative pressure chamber 2, achieving the skin suction effect. Optionally, the negative pressure channel can be constructed as a hose.

[0065] At this point, 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 in a vibration environment. At the same time, combined with the negative pressure cavity 2 and the negative pressure mechanism, the skin can be accurately adsorbed, so that the beauty component 3 can achieve precise vibration massage under the condition of stable adsorption of the skin, and the user experience is optimized and improved.

[0066] Further, continue to refer to Figure 3 In order to achieve the elastic sealing effect, the elastic deformation portion 73 includes a corrugated section 731 bent toward the inside and / or outside. Specifically, 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.

[0067] 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.

[0068] Next, in order to ensure good sealing when the first connecting portion 71 is connected to the beauty component 3, optionally, refer to Figure 3In one embodiment, the first connecting portion 71 only includes a first sealing arm 714, which extends toward the beauty component 3 and is perpendicular to the vibration direction. At this time, the end of the first sealing arm 714 is connected to the peripheral side of the beauty component 3. Usually, the first sealing arm 714 and the beauty component 3 are in sealing contact with each other. Under this setting, 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.

[0069] Optionally, in another embodiment, the first sealing arm 714 is also perpendicular to the vibration direction. Unlike the end-touching method, the position of the beauty component 3 can be adjusted so that the first sealing arm 714 covers 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 covering. 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.

[0070] Further, continue to refer to Figure 2 as well as Figure 3 In this embodiment, the first connecting portion 71 also includes a second sealing arm 715, which is arranged 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 the intersection of the two is also connected to the elastic deformation portion 73. The difference from 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 circumferential side of the vibration mechanism 9.

[0071] At this time, the second sealing arm 715 can improve the connection stability of the first connecting part 71 on the one hand, and on the other hand, an additional sealing surface is formed between the second sealing arm 715 and the vibration mechanism 9, further enhancing the sealing effect of the first connecting part 71, and the function is optimized and improved.

[0072] Furthermore, in order to optimize the connection stability of the second sealing support arm 715, an interlocking step is provided on the peripheral side of the vibration mechanism 9 for the embedding of the second sealing support arm 715. At this time, the interlocking step can enable the sealing ring 7 to be 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.

[0073] Moreover, in this embodiment, while the end of the first sealing arm 714 is connected to the beauty component 3, one side surface of the first sealing arm 714 can also be attached to the end face of the vibration mechanism 9, thereby forming an additional sealing surface, thereby improving the sealing effect, and the vibration mechanism 9 can provide support for the first sealing arm 714, so that the first sealing arm 714 is not easily deformed during the vibration process, and is not easily leaked.

[0074] Reference Figure 2 as well as Figure 3 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. The first sealing segment 723 extends in a direction perpendicular to the vibration direction and is attached to 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.

[0075] However, it should be noted that this setting will cause the sealing ring 7 to be close to the depth of the beauty instrument body 1. Therefore, it is necessary to consider the deformation space of the elastic deformation part 73 to meet the movement freedom requirement of the elastic deformation part 73. By adjusting the size of the beauty component 3 and the length of the vibration mechanism 9, a gap 8 can be formed between the beauty component 3 and the cross-section of the beauty instrument body 1 along the vibration direction. The elastic deformation part 73 is located in the gap 8, so that the elastic deformation part 73 has space for elastic buffering.

[0076] 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 integrally connected; the second sealing segment 724 fits in place with the inner circumferential surface, thereby widening the contact area between the second connecting portion 72 and the beauty instrument body 1, making the sealing ring 7 more stable and firm during assembly and not easy to loosen or leak.

[0077] Principle of Example 1: With the above-described structural arrangement, a sealing structure is obtained that is close to the interior of the beauty instrument body 1 and can provide elastic support. This sealing structure can form a negative pressure cavity 2 that is not easily leaked, meeting the user's beauty needs for negative pressure adsorption and vibration conditions. The result is a beauty instrument product that can accurately adsorb and massage without shifting.

[0078] Example 2:

[0079] However, there is more than one sealing structure that can achieve the above-mentioned function. Here, another structural structure that can achieve the vibration sealing effect is provided, which is also close to the interior of the beauty instrument body 1. The unexplained parts of this embodiment adopt the relevant explanations of Example 1 and are not repeated here.

[0080] Reference Figure 4 and Figure 5 Specifically, the difference between this embodiment and embodiment 1 lies in the different structures of the first connecting portion 71 and the second connecting portion 72. In this embodiment, the first connecting portion 71 is located between the beauty component 3 and the vibration mechanism 9, and the opposite side surfaces of the first connecting portion 71 are respectively connected to the beauty component 3 and the vibration mechanism 9. Through this arrangement, it is equivalent to clamping the first connecting portion 71 between the two, forming a stacked sealing structure, and the sealing effect is further optimized and improved.

[0081] Further, combined with Figure 6 The beauty component 3 has a stepped surface 1009 disposed opposite the end surface of the vibration mechanism 9. Typically, this stepped surface 1009 can be achieved by providing a stepped structure around the periphery of the beauty component 3. Furthermore, the first connecting portion 71 includes a first bent section 716 and a second bent section 717. The second bent section 717 is connected to the elastic deformation portion 73. The first bent section 716 is located on the side of the second bent section 717 away from the elastic deformation portion 73. Typically, the first bent section 716 and the second bent section 717 are integrally connected. The first bent section 716 extends parallel to the vibration direction, while the second bent section 717 extends perpendicular to the vibration direction.

[0082] Based on this, the opposing surfaces of the first bent section 716 are respectively connected to the beauty component 3 and the vibration mechanism 9, and the second bent section 717 is respectively in contact with the end surface of the vibration mechanism 9 and the stepped surface 1009. Here, by configuring the first connecting portion 71 as the first bent section 716 and the second bent section 717, a bent sealing structure is formed, which is equivalent to a two-stage sealing structure, thereby extending the sealing path and improving the sealing effect.

[0083] Furthermore, to enhance the sealing performance between the first connecting portion 71 and the beauty component 3, the beauty component 3 and / or the first connecting portion 71 are provided with a first sealing protrusion 718. Specifically, the first sealing protrusion 718 can be provided in a variety of configurations. In a first configuration, the first sealing protrusion 718 is provided only on the beauty component 3, in which case the first sealing protrusion 718 abuts the first connecting portion 71. In a second configuration, the first sealing protrusion 718 is provided only on the first connecting portion 71, in which case the first sealing protrusion 718 abuts the beauty component 3. In a third configuration, multiple sets of first sealing protrusions 718 are provided, each disposed on the first connecting portion 71 and the beauty component 3. These combinations are not limited in actual configuration. The first sealing protrusion 718 seals the gap between the first connecting portion 71 and the beauty component 3, thereby enhancing the sealing performance between the beauty component 3 and the first connecting portion 71.

[0084] In this solution, the second connection portion 72 is located between the beauty device body 1 and the vacuum sleeve 1a, with the opposing surfaces of the second connection portion 72 connected to the beauty device body 1 and the vacuum sleeve 1a, respectively. This creates a layered seal structure in the area of ​​the second connection portion 72, creating a tighter structure and further optimizing the overall sealing performance of the sealing ring 7 in the area of ​​the second connection portion 72.

[0085] Further, continue to refer to Figure 5 and Figure 6 The end of the second connecting portion 72 forms a hook section 725 folded toward one side, specifically, it can be 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. Correspondingly, 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 hook section 725, so that the hook section 725 can be embedded in the hooking recess 1b1. At this time, with the mutual cooperation of the hook section 725 and the hooking recess 1b1, they can be hooked on the beauty instrument body 1, and the connection between the sealing ring 7 and the beauty instrument body 1 is tighter.

[0086] Furthermore, the negative pressure sleeve 1a is detachable compared to the beauty instrument body 1. This arrangement facilitates the installation of 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 a threaded connection or a snap connection.

[0087] At the same time, refer to Figure 5 、 Figure 6 、 Figure 7The end cover 1c has a snap-fitting protrusion 1c1 at the inner side of the housing 1b. Usually, the snap-fitting protrusion 1c1 is integrally connected to the end cover 1c. The snap-fitting protrusion 1c1 is a sheet structure in this solution, and its size is smaller than the opening size of the hooking recess 1b1, 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 hook section 725, and the installation stability of the second connecting portion 72 is improved, and it is not easy to loosen.

[0088] 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 negative pressure sleeve 1a 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 negative pressure sleeve 1a. 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 negative pressure sleeve 1a and the sealing ring 7, thereby further optimizing the air leakage problem.

[0089] The implementation principle of the second embodiment is that by changing the structural structure of the first connecting portion 71 and the second connecting portion 72, the sealing effect of the negative pressure cavity 2 can also be achieved, thereby meeting the sealing use requirements under vibration adsorption conditions.

[0090] In summary, 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 embodiments can be interchangeably provided, and correspondingly, the second connecting part 72 can also be interchangeably provided. Regardless of the sealing structure adopted by the first connecting part 71 and the second connecting part 72, any solution 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.

[0091] 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.
