When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0032] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0033] The utility model provides a wind cover 200 of a beauty instrument, referring to Figure 1 , Figure 1 It is a schematic diagram of the installation structure of the beauty instrument and the wind cover 200 of the utility model.

[0034] In this embodiment, the beauty instrument includes a main body 100, and a wind hood 200 is arranged in the main body 100. The wind hood 200 includes a first docking shell 201 and a second docking shell 202 that are detachably connected. The first docking shell 201 and the second docking shell 202 are combined to form a accommodating cavity; one end of the first docking shell 201 and the second docking shell 202 is configured with a mounting portion 300 for clamping the filter F.

[0035] In this embodiment, the main body 100 of the beauty instrument not only serves as the outer shell of the device, providing an aesthetic appearance and protection, but also provides installation space for internal components. Among them, some functional coatings can be applied internally, for example, a reflective coating, which can reflect unnecessary light wavelengths and only allow light wavelengths with therapeutic effects to pass through, thereby improving the efficiency and safety of phototherapy while reducing energy loss. Of course, it can also be a coating with other functions, such as an antibacterial coating, a thermal conductive layer, etc. For example, the antibacterial coating contains a substance that can inhibit bacterial growth. This coating can prevent bacteria from growing in the accommodating cavity, keep the equipment hygienic, reduce the risk of cross infection, and improve the overall hygiene level of the equipment. As the name implies, the thermal conductive layer is used to improve the efficiency of heat conduction and help the equipment dissipate heat better. This coating can conduct the heat generated from the light-emitting element 5 more effectively, maintain the appropriate operating temperature of the equipment, and extend the service life of the equipment.

[0036] In this embodiment, the wind shield 200 inside the main body 100 is formed by a first docking shell 201 and a second docking shell 202 that are detachably connected. The two half shells enclose a housing cavity. In this embodiment, the design of this housing cavity not only serves as an air duct to guide the cooling airflow and maintain the appropriate working temperature of the device, but also has the function of installing the filter F. Through this design, the filter F can be directly installed near the light outlet 400 without the need for an additional bracket, thereby simplifying the structure and reducing costs. In addition, the design of the housing cavity also takes into account the wavelength selective absorption, transmission or reflection characteristics of the filter F, as well as the interference effect of the multi-layer film system, to ensure that the light emitted by the beauty instrument can be effectively used for beauty after being processed by the filter F.

[0037] During the product assembly process, the filter F only needs to be snapped into the mounting portion 300 of the wind shield 200. The mounting portion 300 in this embodiment is composed of a third mounting protrusion 301 of the first docking shell 201 and a fourth mounting protrusion 302 of the second docking shell 202. These protrusions are arranged along the inner wall of the light outlet 400 and protrude toward the center of the light outlet 400 to form a first slot. The edge of the filter F is snapped into this slot and fixed in place by the first limiting protrusion 303 and the second limiting protrusion 304. In this way, the filter F is firmly mounted in front of the light outlet 400, and light of a specific wavelength can be selectively allowed to pass through to achieve the desired cosmetic effect.

[0038] In the technical solution of this embodiment, since the wind cover 200 is configured as two detachably connected half-shell structures, when the first docking shell 201 and the second docking shell 202 are buckled, a mounting portion 300 for clamping the filter F is formed between the first docking shell 201 and the second docking shell 202, and an airflow channel for guiding the airflow direction is formed. Compared with the existing solution of separately configuring a bracket for mounting the filter F, the beauty instrument of this embodiment, the mounting portion 300 of the filter F is formed by combining with the airflow channel of the wind cover 200, and the structure is compact, and it is no longer necessary to separately add a filter F mounting bracket, thereby reducing the production cost.

[0039] See also Figure 2 , Figure 2 It is a schematic diagram of the structure of the wind cover 200 of the beauty instrument of the present invention.

[0040] In this embodiment, the air cover 200 is provided with a light outlet 400 , which is constructed on the side walls of the first docking shell 201 and the second docking shell 202 , and the mounting portion 300 is formed on the inner wall of the light outlet 400 .

[0041] In this embodiment, the mounting portion 300 of the wind shield 200 can be directly constructed on the inner wall of the light outlet 400 by an integrated molding technology. This integrated molding design allows the mounting portion 300 to form a continuous unit with the side walls of the first docking shell 201 and the second docking shell 202 of the wind shield 200, without the need for additional components or a complicated assembly process. In addition to integrated molding, the mounting portion 300 can also be formed by other methods, such as using bonding, welding or mechanical fasteners. When selecting the forming method, manufacturing cost, structural strength and maintenance convenience are taken into consideration.

[0042] During the assembly process, the filter F is first aligned with the mounting portion 300 on the first docking shell 201, and then slid along the inner wall of the light outlet 400 until the filter F is firmly inserted into the mounting portion 300, and then the second docking shell 202 is assembled with the first docking shell 201 in a positive manner, so that the filter F is inserted between the first docking shell 201 and the second docking shell 202 and is located in the mounting portion 300. Since the mounting portion 300 is integrally formed, this process is very simple and quick, and no tools are required. Once the filter F is installed in place, it can fit tightly with the inner wall of the light outlet 400, ensuring that light can be effectively filtered and adjusted when passing through the filter F.

[0043] In this embodiment, the one-piece mounting portion 300 is used, which not only simplifies the manufacturing and assembly process of the wind shield 200, but also improves the stability and durability of the overall structure. At the same time, the number of parts is reduced, the production cost is reduced, and it is convenient for users to replace and maintain the filter F in daily use. In addition, the one-piece mounting portion 300 provides better sealing, prevents dust and moisture from entering, protects internal components, and extends the service life of the device.

[0044] See also Figure 3 and Figure 4 , Figure 3 This is an exploded schematic diagram of the wind cover 200 of the beauty instrument of the present invention. Figure 4 for Figure 3 A magnified schematic diagram of center A.

[0045] In this embodiment, the mounting portion 300 includes a first slot 303 a , which is disposed along the inner wall of the light outlet 400 and is used for mounting the filter F therein.

[0046] In this embodiment, the first card slot can be composed of a first card slot 303a and a second card slot 304a, so as to be used for carding the optical filter F. In addition to using the first card slot 303a and the second card slot 304a, the mounting portion 300 can also use other methods to fix the optical filter F. For example, a magnetic fixing method can be designed, in which the optical filter F and the mounting portion 300 are mutually attracted by magnetic force, so as to achieve rapid installation and removal. In addition, a rotation locking mechanism can also be used to lock or release by rotating the optical filter F, which can also provide a stable fixation while maintaining the convenience of replacement.

[0047] In this embodiment, first, the edge of one end of the filter F is inserted into the first slot 303a, and then the second docking shell 202 is buckled, so that the other end of the filter F slides into the second slot 304a, ensuring that the filter F has contact points in both slots. This dual-slot design provides double fixation, ensuring the stability and correct position of the filter F during use. When the filter F needs to be replaced, it can be easily removed by simply reversing the operation. This design not only ensures the fixing effect of the filter F, but also facilitates the use of the user.

[0048] Furthermore, the first slot 303a and the second slot 304a may be formed by providing a protrusion on the half shell. Figure 2 In this embodiment, the first card slot includes a third mounting protrusion 301 provided on the first docking shell 201 and a fourth mounting protrusion 302 provided on the second docking shell 202. The third mounting protrusion 301 and the fourth mounting protrusion 302 protrude from the inner wall of the light outlet 400 toward the center of the light outlet 400.

[0049] In this embodiment, the first card slot and the second card slot can be formed by providing protrusions on the first docking shell 201 and the second docking shell 202. These protrusions can be formed directly on the half shells through a precise mold manufacturing process, which can ensure the accuracy of the size and position of the protrusions. The third mounting protrusion 301 and the fourth mounting protrusion 302 are designed to protrude from the inner wall of the light outlet 400 toward the center of the light outlet 400. This design allows the filter F to slide into place along the protrusions during installation and be firmly supported at the protrusions. At the same time, the provision of the protrusions can lock the filter F in the accommodating cavity to prevent the filter F from falling out.

[0050] The protrusion of the previous embodiment can prevent the filter F from falling out of the accommodating cavity, thus avoiding accidents during use. However, since an air duct is formed inside the accommodating cavity, that is, when the beauty instrument is inverted (the light outlet 400 faces upward), the filter F may fall into the accommodating cavity. If the filter F is not restricted, there may be some safety hazards. Figure 4 In this embodiment, the mounting slot further includes a first limiting protrusion 303, which protrudes from the inner wall of the light outlet 400 toward the center of the light outlet 400 and is spaced apart from the third mounting protrusion 301; and / or

[0051] The mounting slot further includes a second limiting protrusion 304 , which protrudes from the inner wall of the light outlet 400 toward the center of the light outlet 400 and is spaced apart from the fourth mounting protrusion 302 .

[0052] In this embodiment, the first limiting protrusion 303 is mainly used to limit the possibility of the filter F falling into the receiving groove. The provision of the first limiting protrusion 303 and the second limiting protrusion 304 not only enhances the fixing effect of the filter F, but also provides additional safety protection. These protrusions can be formed directly on the inner wall of the light outlet 400 by precision technology, and are spaced apart from the third mounting protrusion 301 and the fourth mounting protrusion 302 to form a safety structure that limits the movement of the filter F.

[0053] During operation, the filter F is first clamped in the first clamping slot and the second clamping slot, and then the first limiting protrusion 303 and the second limiting protrusion 304 serve as additional support points to ensure that the filter F will not fall off even when the device is inverted. This design effectively limits the movement of the filter F in the accommodating cavity and improves safety during use.

[0054] This design not only ensures the stability of the filter F in normal use, but also takes into account the safety of the device in abnormal use. The addition of the first limiting protrusion 303 and the second limiting protrusion 304 prevents the filter F from falling off even when the device is inverted, thereby protecting the user from accidental injury and ensuring the continuity and stability of the phototherapy effect.

[0055] To ensure that the two half shells can stably hold the filter F, the tightness of the two half shells plays a crucial role, which can be seen from Figure 4 As can be seen in the figure, in this embodiment, a clamping member 201a is provided on one side of the first docking shell 201 facing the second docking shell 202, and a clamping groove 202a is provided on one side of the second docking shell 202 facing the first docking shell 201. The clamping groove 202a is plugged into and matched with the clamping member 201a, so that the first docking shell 201 and the second docking shell 202 are relatively fixed.

[0056] In this embodiment, the first docking shell 201 and the second docking shell 202 are locked by snap-fit. This fastening structure is simple and easy to manufacture. Of course, in addition to the snap-fit ​​method, there are other methods to achieve stable fastening of the first docking shell 201 and the second docking shell 202. For example, magnets or magnetic materials are used to form a magnetic attraction effect at the corresponding positions of the half shells, which can quickly and conveniently fix the two half shells and is also easy to disassemble. Considering the airtightness, a buckle and notch design can be adopted, that is, a buckle is designed on one half shell and a corresponding notch is designed on the other half shell, and the buckle fixation of the half shells is achieved through the elastic deformation of the buckle.

[0057] In this embodiment, the cooperation between the clamping member 201a and the clamping groove 202a provides a stable and reliable connection method for the first docking shell 201 and the second docking shell 202. This method not only makes the assembly process simple and fast, but also allows the user to easily fasten the two half shells together without any additional tools or devices. At the same time, it also ensures a tight fit between the two.

[0058] Continue reading Figure 4 In this embodiment, it also includes: a rib 500, which surrounds the light outlet 400 and is arranged on the outer side walls of the first docking shell 201 and the second docking shell 202.

[0059] In this embodiment, the head of the beauty instrument is also provided with an electrode circuit board E electrically connected to the auxiliary light source or the electrode. The design of the rib 500 is mainly used to prevent light leakage during the assembly process of the wind hood 200 and the electrode circuit board E. At the same time, the design of the rib 500 can also enhance the structural stability of the wind hood 200.

[0060] The rib 500 surrounds the light outlet 400 and is disposed on the outer side walls of the first docking shell 201 and the second docking shell 202, forming a reinforcement ring. This reinforcement ring not only provides additional mechanical strength, but also prevents deformation and damage during assembly or use; the electrode circuit board E is constructed with a avoidance opening of the same size as the light outlet 400, which is mainly used for the light source generated by the light-emitting element 5 to pass through, and the rib 500 can be embedded in the avoidance opening, thereby ensuring the sealing around the light outlet 400 and effectively preventing the leakage of light.

[0061] When assembling the electrode circuit board E, the ribs 500 can fit closely with the electrode circuit board E to form a barrier to prevent light leakage. In this way, even if there is a small gap between the electrode circuit board E and the wind shield 200, the ribs 500 can block the light from penetrating, ensuring that the light of the beauty instrument can only be emitted through the light outlet 400 and the filter F, thereby improving the beauty effect. It is understandable that in other embodiments, the head of the beauty instrument is not equipped with electrodes and auxiliary light emitters, and the ribs 500 can be directly assembled with the light outlet 400.

[0062] In some embodiments, the wind shield 200 of the beauty instrument further includes a third opening 610 and a second opening 620, wherein the third opening 610 is disposed at an end away from the light outlet 400, and the second opening 620 is disposed at an end close to the light outlet 400;

[0063] The third opening 610 is formed in the first docking shell 201 and / or the second docking shell 202 , and the second opening 620 is formed in the first docking shell 201 and / or the second docking shell 202 .

[0064] In this embodiment, the third opening 610 and the second opening 620 are designed to connect the accommodating cavity to form an effective airflow channel, which allows air to flow freely, thereby helping to dissipate the heat generated by the light-emitting element 5 during operation. This airflow design not only improves the heat dissipation efficiency of the device, but also helps to maintain a stable temperature inside the device, thereby protecting the electronic components and extending the service life of the device.

[0065] There are many ways to form the third opening 610, wherein the third opening 610 can be formed on the first docking shell 201 alone, and the second opening 620 can be formed on the second docking shell 202 alone, or both can be formed together when the first docking shell 201 and the second docking shell 202 are buckled. This flexible design makes the manufacturing and assembly process of the wind shield 200 easier, and also provides convenience for the maintenance and repair of the equipment.

[0066] In some embodiments, in order to enhance the heat dissipation efficiency, a heat dissipation fan may be provided at the third opening 610 and / or at the second opening 620 to enhance the fluidity of the airflow in turn, thereby achieving better heat dissipation efficiency.

[0067] In some embodiments, there is a height difference between the third opening 610 and the second opening 620. For example, the third opening 610 is used as an air outlet, and the second opening 620 is used as an air inlet. The third opening 610 is located higher than the second opening 620. According to the rising and falling principle of hot and cold air, hot air will rise and cold air will fall. Setting the third opening 610 (air outlet) higher than the second opening 620 (air inlet) can promote the natural rise of hot air and discharge from the upper opening, while sucking in cold air from the lower opening, forming effective natural convection.

[0068] This height difference setting can also accelerate the circulation of airflow, and cooperate with the heat dissipation fan to allow the heat generated by the light-emitting element 5 to be taken away more quickly, thereby improving the heat dissipation efficiency and maintaining a stable temperature inside the device.

[0069] The utility model also discloses a beauty instrument, including a light-emitting component 5 and the aforementioned wind cover 200 of the beauty instrument. The specific structure of the wind cover 200 of the beauty instrument refers to the above embodiment. Since the beauty instrument adopts all the technical solutions of all the above embodiments, it at least has all the technical effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the light-emitting component 5 is arranged in the accommodating cavity and located on the inner side of the light outlet 400. The light emitted by the light-emitting component 5 is output from the light outlet 400 after passing through the filter F.

[0070] In this embodiment, after the first docking shell 201 and the second docking shell 202 are buckled together, the light-emitting component 5 is installed between the first docking shell 201 and the second docking shell 202, and the light-emitting component 5 is located near the third opening 610 or the second opening 620. Such a design can make the light-emitting component 5 better contact with the flowing airflow, thereby improving the heat dissipation efficiency; in addition, as for the conduction mode of the light-emitting component 5, there are multiple modes, among which it can be directly electrically connected to the main control circuit board 110 of the device, and of course, it can also be connected to the electric control system through the electrode circuit board E, which is not particularly limited here.

[0071] The beauty instrument can ensure that the light emitted by the beauty instrument is safe for the skin and does not cause harm by precisely controlling the light intensity and wavelength of the light emitting element 5 and using a specific filter F. In addition, the light processed by the filter F can treat the skin in a targeted manner, such as improving skin pigmentation, promoting collagen production, etc., thereby achieving a beauty effect.

[0072] Furthermore, the beauty instrument can adjust the intensity of light and the type of filter F according to the skin types and beauty needs of different users to provide personalized beauty solutions.

[0073] In some embodiments, an airflow generating device 203 is also included;

[0074] The airflow generating device 203 is disposed outside the accommodating cavity, the airflow output port of the airflow generating device 203 is connected to the third opening 610, and the airflow delivered by the airflow generating device 203 passes through the third opening 610, the accommodating cavity and the second opening 620 in sequence; or,

[0075] The airflow generating device 203 is disposed in the accommodating cavity, the airflow input port of the airflow generating device 203 is connected to the third opening 610, and the airflow delivered by the airflow generating device passes through the third opening 610, the accommodating cavity and the second opening 620 in sequence; or,

[0076] The airflow generating device 203 is disposed in the accommodating cavity, and the airflow output port of the airflow generating device 203 is connected to the third opening 610 . The airflow delivered by the airflow generating device passes through the second opening 620 , the accommodating cavity and the third opening 610 in sequence.

[0077] In this embodiment, the airflow generating device 203 is a component for dissipating heat and cooling the light emitting element 5 in the accommodating cavity, and a heat dissipation fan may be used.

[0078] The design flexibility of the airflow generating device 203 allows it to be installed outside the accommodating cavity or inside the accommodating cavity. When installed outside the accommodating cavity, the airflow generating device 203 is connected to the third opening 610 through the airflow output port, effectively delivering the airflow into the accommodating cavity. When installed inside the accommodating cavity, the airflow generating device 203 is located at the third opening 610, the airflow input port of the airflow generating device 203 is connected to the third opening 610, and the exhaust end is inside the accommodating cavity, thereby achieving direct ventilation of the interior of the accommodating cavity.

[0079] In one embodiment, in addition to injecting airflow into the accommodating cavity, the airflow in the accommodating cavity can also be discharged to dissipate heat and cool down. Specifically, the airflow generating device 203 is also arranged in the accommodating cavity, and the airflow output port of the airflow generating device 203 is connected to the third opening 610. The airflow delivered by the airflow generating device 203 is discharged from the wind hood through the second opening 620, the accommodating cavity and the third opening 610 in sequence.

[0080] In summary, no matter whether the airflow generating device 203 is installed outside or inside the accommodating cavity, its working principle remains the same. After the airflow generating device 203 is started, the airflow starts from the airflow output port or input port, passes through the third opening 610 and the inside of the accommodating cavity in sequence, and finally is discharged through the second opening 620 or its third opening 610. In this process, the flow of airflow not only takes away the heat inside the accommodating cavity, but also ensures the air pressure balance and air circulation inside the beauty instrument.

[0081] In this embodiment, the addition of the airflow generating device 203 brings multiple benefits to the beauty instrument. First, it improves the heat dissipation efficiency of the device and prolongs the service life of the beauty instrument. Second, the design of the airflow generating device 203 can reduce the heat generated by the light-emitting element 5 from being transferred to the user's skin, so that the user's skin remains cool and the comfort level is improved.
