Abstract
Description
Technical Field
[0001] This application relates to the field of beauty devices, and particularly to beauty devices.
Background Art
[0002] With the continuous improvement of living standards, beauty devices have gradually integrated into people's daily lives, using beauty devices to care for and repair the skin to make the appearance beautiful.
[0003] During the operation of many beauty devices, their internal related devices generate heat, so it is necessary to dissipate the heat generated by the related devices inside the beauty device. The hair remover can be used, for example, to remove armpit and leg hair from the body. In a hair remover, when a laser irradiates the hair on the skin, the melanin in the hair absorbs the laser energy and converts it into heat energy, deeply penetrates into the hair follicles, and destroys the hair follicles to achieve the hair removal effect.
[0004] During the operation of the hair remover, a lot of heat is generated inside it. In order to discharge the heat in a timely manner, usually, a heat dissipation device is installed inside the hair remover. However, in existing hair removers, local overheating still exists during use, and its heat dissipation effect is poor.

Mode for Carrying Out the Invention
[0039] The realization of the object, functional features and advantages of the present application will be further described with reference to the drawings in conjunction with the embodiments.
[0040] Hereinafter, in conjunction with the drawings in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. It is obvious that the described embodiments are only a part of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments that can be obtained by those skilled in the art without creative efforts shall be included in the protection scope of the present application.
[0041] It should be noted that all the direction indications (for example, up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship and movement between each component in a specific posture (as shown in the drawings). When the specific posture changes, the direction indications will also change accordingly.
[0042] Also, when an element is said to be "fixed to" or "provided on" another element, it should be explained that the element may be directly arranged on the other element, or there may be a central element between them at the same time. When an element is said to be "connected to" another element, the element may be directly connected to the other element, or there may be a central element between them at the same time.
[0043] Furthermore, the terms "first" and "second" mentioned in this application are merely for the purpose of explanation and should not be understood as indicating or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined by "first" and "second" may explicitly or implicitly include at least one such feature. Furthermore, the technical solutions between the embodiments can be combined with each other on the premise that those skilled in the art can implement them. However, if such a combination is contradictory or cannot be implemented, such a combination does not exist and should not be considered as included in the protection scope claimed in this application.
[0044] The embodiments of this application propose a beauty device. Referring to FIGS. 1 to 9, the beauty device includes at least a housing 10, a beauty assembly, and a heat dissipation assembly. Both the beauty assembly and the heat dissipation assembly are provided inside the housing 10. Here, the beauty assembly is used to care for the surface of the human skin and generates heat inside the housing 10 during operation. The heat dissipation assembly is used to discharge the heat inside the housing 10 to the outside to prevent the housing 10 from generating heat due to heat concentration. The heat dissipation assembly generally includes an air flow generating device and a heat sink 42. The heat sink 42 is used to receive the heat inside the housing 10. The air flow generating device is used to generate a cooling air flow and flow it into the heat sink 42, carry the heat on the heat sink 42 out by the cooling air flow, and discharge it through the air discharge hole 12 opened in the housing 10. As can be understood, the cooling air flow generated by the air flow generating device flows into the housing 10 through the air inlet hole 13 opened in the housing 10 from the outside.
[0045] Optionally, the beauty device proposed in the embodiments of the present application may be a laser hair removal device, a skin rejuvenation device, a whitening device, an ultrasonic beauty device, etc., but is not limited thereto, and those skilled in the art can design according to the actual situation. Hereinafter, the technical solutions proposed in the embodiments of the present application will be described by taking a hair removal device as an example. In this case, the beauty assembly may include a hair removal assembly 20 and a cooling assembly 30. The hair removal assembly 20 may include a light source. A first light emitting port 11 may be opened in the housing 10. The light source of the hair removal assembly 20 is used to emit light toward the first light emitting port 11 of the housing 10. This light is received by the cooling assembly 30 and irradiated onto the human skin to remove hair from the skin. When the human skin is irradiated with light, it receives light energy, converts it into internal energy and generates heat. In order to improve the user experience, the cooling assembly 30 may be brought into contact with the human skin. Since the surface temperature of the cooling assembly 30 is low, it can reduce the heat sensation of the human body when in contact with the human body.
[0046] Note that the cooling sensation assembly 30 includes a semiconductor cooling sheet 31 and a lens 32. The semiconductor cooling sheet 31 has a cooling surface and a heating surface. The cooling surface of the semiconductor cooling sheet 31 is connected to the lens 32. When the semiconductor cooling sheet 31 operates, the cooling surface cools and transfers cold energy to the lens 32. As a result, the temperature of the lens 32 for contacting human skin becomes relatively low, providing a calming and cooling sensation effect on the skin, and alleviating skin burns caused by the light emitted from the hair removal assembly 20 or discomfort caused by a relatively high temperature. When the semiconductor cooling sheet 31 operates, the heat generated on the heating surface is conducted to the heat sink 42 through the heat conducting member 60. Optionally, the lens 32 includes sapphire. That is, the heat sink 42 of the hair removal device is mainly used to dissipate the heat of the heating surface of the semiconductor cooling sheet 31. As understood, the light emitted from the hair removal assembly 20 can pass through the lens 32 and irradiate human skin, thereby removing hair from the area of the skin being cared for and obtaining a calming and cooling sensation effect. Also, the light emitted from the hair removal assembly 20 may irradiate human skin by passing around the lens 32 without passing through the lens 32. The lens 32 does not directly provide a cooling sensation to the skin at the hair removal site, but can also alleviate discomfort caused by the high temperature of the skin by providing a cooling sensation to the skin around the hair removal site.
[0047] Optionally, in order to enhance the heat dissipation effect of the hair remover, the heat sink 42 is provided with an air inlet K2, a first air outlet K1, and a second air outlet K3. Here, the air inlet K2 is docked to the air outlet of the air flow generating device, the first air outlet K1 is provided towards the air discharge hole 12 on the housing 10, the second air outlet K3 is located on a side wall of the heat sink 42 different from that of the first air outlet K1, and the second air outlet K3 is mainly used to release the pressure inside the heat sink 42 to ensure that the cooling air flow can flow to multiple locations of the heat sink 42 for heat exchange. When dissipating heat, the cooling air flow generated by the air flow generating device flows into the heat sink 42 through the air inlet K2. A part of the cooling air flow flows out of the heat sink 42 through the second air outlet K3 and then out of the housing 10. Another part of the cooling air flow flows out of the housing 10 through the first air outlet K1 after completing heat exchange inside the heat sink 42. In addition, due to the arrangement of the second air outlet K3, the air pressure difference inside and outside the heat sink 42 is reduced. Therefore, after the cooling air flow flows into the heat sink 42 from the air inlet K2, it is dispersed to various locations inside the heat sink 42 for heat exchange, and then can flow out of the heat sink 42 through the first air outlet K1 and the second air outlet K3 respectively. In this way, the heat sink 42 dissipates heat uniformly, and local overheating is effectively improved.
[0048] Furthermore, since the main role of the second air outlet K3 is to release pressure (i.e., reduce the air pressure inside the heat sink), the diameter of the second air outlet K3 is smaller than that of the first air outlet K1. Only a very small portion of the cooling air flow flows out of the heat sink 42 to the outside of the heat sink 42 through the second air outlet K3 after heat exchange inside the heat sink 42, and then is discharged from the air discharge hole 12 of the housing 10. However, most of the cooling air flow flows out of the housing 10 from the first air outlet K1 after heat exchange inside the heat sink 42. That is, in the embodiment where the first air outlet K1 is directly provided toward the air discharge hole 12 on the housing 10, the cooling air flow that has flowed into the heat sink 42 is divided into two parts after completing heat exchange and flows out of the heat sink 42 to the outside. Most of the cooling air flow flows out of the housing 10 directly through the air discharge hole 12 on the housing 10 after heat exchange inside the heat sink 42. Therefore, it improves the local overheating of the housing, speeds up the discharge of the hot air flow, and improves the heat dissipation efficiency.
[0049] Optionally, the air flow generating device may include a fan, and the cooling air generated by the fan is sent to the heat sink 42 to dissipate heat from the heat sink 42.
[0050] Optionally, to further enhance the heat dissipation effect of the hair remover, the heat sink 42 may have a third air outlet K4. The role of this third air outlet K4 is the same as that of the second air outlet K3. Both are used to release the pressure inside the heat sink 42 and ensure that the cooling air flow can flow more smoothly, uniformly, and extensively. In some embodiments, the heat sink 42 of the hair remover has both a second air outlet K3 and a third air outlet K4. The diameter of the third air outlet K4 is smaller than that of the first air outlet K1. Here, the diameter of the third air outlet K4 may also be smaller than that of the second air outlet K3. When dissipating heat, the cooling air flow generated by the air flow generating device flows into the heat sink 42 through the air inlet K2. A part of the cooling air flow flows out of the heat sink 42 through the second air outlet K3 and then out of the housing 10. Another part of the cooling air flow flows out of the heat sink 42 through the third air outlet K4 and then out of the housing 10. Yet another part of the cooling air flow flows out of the housing 10 through the first air outlet K1 after completing heat exchange inside the heat sink 42. That is, the cooling air flow that flows into the heat sink 42 is divided into three parts and flows out of the heat sink 42 to the outside after completing heat exchange, and finally flows out of the housing 10 through the air discharge holes 12 on the housing 10. When having both the second air outlet K3 and the third air outlet K4, the flow of the cooling air flow is smoother, more uniform, and more extensive, which can significantly improve the heat dissipation effect of the heat sink 42, avoid local overheating, and enhance the user experience. In some embodiments, the cooling air flow that flows out of the heat sink 42 through the third air outlet K4 may flow back into the housing 10 and then flow into the heat sink 42 under the action of the air flow generating device.
[0051] Note that although a part of the hot air will flow backward into the housing 10 due to the openings of the second air outlet K3 and the third air outlet K4, as can be seen from experiments, the heat dissipation effect of the heat sink 42 with the second air outlet K3 and the third air outlet K4 opened is significantly improved, and compared with the hot air flowing backward into the housing 10 from the second air outlet K3 and the third air outlet K4, its heat influence can basically be ignored.
[0052] Optionally, referring to FIGS. 3 and 10, the depilator may include a central frame 10B, which is distributed around the heat sink 42 and is provided in a substantially U-shape. One end of the central frame 10B and the air inlet K2 of the heat sink 42 are jointly docked to the air outlet of the air flow generating device, that is, the cooling air flow generated by the air flow generating device is divided into two parts and flows into the heat sink 42 and the central frame 10B respectively, and the other end of the central frame 10B communicates with the air discharge hole 12 on the housing 10. The depilation assembly 20 is provided in the central frame 10B, and the heat generated by the depilation assembly 20 is carried out by the cooling air flow flowing into the central frame 10B and discharged to the outside of the housing 10 through the air discharge hole 12 on the housing 10. That is, the cooling air flow generated by the air flow generating device is first divided into two parts and flows into the heat sink 42 and the central frame 10B respectively, and the cooling air flow flowing into the heat sink 42 can be further divided into at least two parts according to the actual structural design, and the details can refer to the foregoing content and will not be repeated here. In some embodiments, the cooling air flow generated by the air flow generating device is first divided into two parts and flows into the heat sink 42 and the central frame 10B respectively, and the cooling air flow flowing into the heat sink 42 is further divided into three parts, that is, it flows to the first air outlet K1, the second air outlet K3 and the third air outlet K4 respectively.
[0053] Optionally, in addition to the hair removal assembly 20, the hair removal device may further include a skin care assembly. The skin care assembly includes a skin care lamp, and the light emitted from the skin care lamp irradiates the human skin through the cooling assembly 30 to achieve skin care of the skin. When using the hair removal device, the user can turn on the hair removal function and the skin care function of the hair removal device at the same time, that is, control the skin care assembly and the hair removal assembly 20 to operate simultaneously, so as to perform hair removal and skin care on the human body at the same time. Of course, it is also possible to use the hair removal function and the skin care function of the hair removal device separately, and control the switching on of the hair removal function and the skin care function of the hair removal device with two different buttons respectively, and also control the operation and opening and closing of the hair removal assembly 20 and the skin care assembly.
[0054] The above mainly describes the heat dissipation of the hair removal device. The following will describe in detail the specific structural design of the heat sink 42 proposed in this application.
[0055] In some embodiments, referring to FIGS. 6 to 8, the air inlet K2 and the second air outlet K3 are respectively located on both sides of the first air outlet K1. The heat sink 42 further has a third air outlet K4 located on the same side as the air inlet K2 for relieving pressure. The size of the third air outlet K4 is smaller than the size of the first air outlet K1, and the third air outlet K4 is offset from the air inlet K2 and away from the first air outlet K1.
[0056] In some embodiments, referring to FIGS. 6 to 9, the heat sink 42 includes a plurality of heat dissipation fins 422 provided at intervals. A plurality of openings in different directions are formed between two adjacent heat dissipation fins 422. Each opening leading to the air discharge hole 12 jointly forms the first air outlet K1. At least a part of each opening leading to the beauty assembly jointly forms the second air outlet K3. Each opening leading to the air flow generating device jointly forms the air inlet K2 and the third air outlet K4.
[0057] In this embodiment, the heat sink 42 includes a plurality of heat dissipation fins 422, and the gap between two adjacent heat dissipation fins 422 is formed as a first passage for the cooling air flow to flow through therein and exchange heat with the heat dissipation fins 422. The first passage has a plurality of openings located in different directions, which are respectively an opening towards the air discharge hole 12, an opening towards the air flow generating device, and an opening towards the beauty assembly, and the openings in different directions communicate with the first passage respectively. Optionally, each opening towards the air discharge hole 12 forms a first air discharge port K1 in combination, each opening towards the beauty assembly forms a second air discharge port K3 in combination, and each opening towards the air flow generating device forms an air inlet K2 and a third air discharge port K4 in combination.
[0058] In some embodiments, a first stopper 421 is provided at a part of each opening towards the beauty assembly, and the first stopper 421 guides the cooling air flow flowing in from the air inlet K2 to flow towards the first air discharge port K1 and is used to discharge the cooled air flow after heat exchange to the outside through the air discharge hole 12.
[0059] In this embodiment, a part of each opening on the side of the heat sink 42 close to the beauty assembly is shielded by the first stopper 421, and the remaining unshielded part of the opening forms the second air discharge port K3 jointly. The air pressure inside the heat sink 42 is released through the second air discharge port K3, thereby enabling the cooling air flow to flow substantially to each part of the heat sink 42. A part of the cooling air flows towards the first air discharge port K1 after flowing through the first stopper 421 and then flows out of the housing 10 through the air discharge hole 12 on the housing 10.
[0060] In some embodiments, the housing 10 includes a hand-held portion 14 and a care head 15, the connection between the hand-held portion 14 and the care head 15 is curved in an arc, the cosmetic assembly and the heat sink 42 are disposed within the care head 15, the heat sink 42 is located at one end of the care head 15 connected to the hand-held portion 14, the cosmetic assembly is located at the other end of the care head 15, and the airflow generating device is disposed at one end of the hand-held portion 14 adjacent to the care head 15.
[0061] In this embodiment, the housing 10 includes a hand-held portion 14 and a care head 15 connected thereto, and the connection portion between the hand-held portion 14 and the care head 15 has a curved arc shape, so that when the user holds the hand-held portion 14 vertically, the surface of the care head 15 that contacts human skin faces the human body, and the user can perform skin care by simply tilting the hand-held portion 14 slightly toward the human body so that the surface of the care head 15 that contacts the skin fits the skin, thus making the beauty device more ergonomic and easy to hold, and better fitting the human skin, improving the use effect of the epilator. Optionally, the beauty assembly and heat sink 42 are provided in the care head 15, and the airflow generating device is provided at one end of the hand-held portion 14 close to the care head 15.
[0062] In some embodiments, referring to FIG. 9, one side of each of the heat dissipation fins 422 has a protrusion 4221, and each of the protrusions 4221 includes an intersecting first edge 4221a and a second edge 4221b, and the opening between each two adjacent first edges 4221a forms the air inlet K2 docked to the airflow generating device, and a second stopper 423 is provided at the opening between each two adjacent second edges 4221b.
[0063] In this embodiment, in order to adapt to the curved configuration of the housing 10 and enable the heat sink 42 to dock with the airflow generating device, one side of each heat dissipation fin 422 has a protrusion 4221, whereby it is docked to the air outlet of the airflow generating device via the protrusion 4221. The protrusion 4221 is located on the side of the heat dissipation fin 422 close to the airflow generating device, and includes a first edge 4221a and a second edge 4221b, and the first edge 4221a and the second edge 4221b are provided so as to form an angle. The openings between every two adjacent first edges 4221a together form an air inlet K2 docked to the airflow generating device, and a second stopper 423 is provided in the opening between every two adjacent second edges 4221b, thereby preventing the cooling airflow from flowing back into the housing 10 in a direction away from the air discharge hole 12 from the opening between every two adjacent second edges 4221b after heat exchange, and thereby enhancing the heat dissipation effect of the hair remover. Optionally, the angle between the first edge 4221a and the second edge 4221b is an acute angle.
[0064] In some embodiments, referring to FIG. 9, each of the heat dissipation fins 422 further has a third edge 4222 on the same side as the protrusion 4221 and intersecting the second edge 4221b, and the opening between every two adjacent third edges 4222 forms a third air outlet K4 of the heat sink 42.
[0065] In this embodiment, in order to reduce the air pressure difference between the inside and the outside of the heat sink 42, the openings between every two adjacent third edges 4222 combine to form the third air discharge port K4 of the heat sink 42. The function of the third air discharge port K4 is the same as that of the second air discharge port K3, and it is used to release the pressure of the heat sink 42. Optionally, the third edge 4222 intersects the second edge 4221b and is located on the same side as the protrusion 4221. Note that due to the formation region of the third edge 4222, on the one hand, it can conform to the lamination of the internal structure of the beauty device and make the internal laminated structure more stable and compact. On the other hand, it can increase the heat dissipation area of the entire heat sink 42. However, in this region, high pressure is likely to occur during heat dissipation. Therefore, in order to further ensure that the cooling air flow flows more smoothly, uniformly, and widely, a third air discharge port K4 for releasing pressure is formed at one end of every two adjacent third edges 4222.
[0066] In some embodiments, referring to FIG. 9, each of the heat dissipation fins 422 further has a fourth edge 4223 that is on the same side as the protrusion 4221 and intersects the first edge 4221a. The fourth edge 4223 extends toward the air discharge hole 12, and a third stopper 424 is provided at the opening between every two adjacent fourth edges 4223.
[0067] In this embodiment, in order to discharge the hot air after heat exchange from the air discharge hole 12 as much as possible, each heat dissipation fin 422 further has a fourth edge 4223 that is on the same side as the protrusion 4221. The fourth edge 4223 extends toward the air discharge hole 12 and is extremely close to it. In order to prevent the hot air flow from flowing back into the housing 10 through the opening between every two adjacent fourth edges 4223, a third stopper 424 for blocking the backflow of the hot air flow is provided at the opening between every two adjacent fourth edges 4223.
[0068] In some embodiments, referring to FIG. 5, on one side of each of the third edges 4222, a fourth stopper 425 is provided. The fourth stopper 425 is provided at an interval from each of the third edges 4222, and the fourth stopper 425 is located between the housing 10 and the heat sink 42.
[0069] In this embodiment, a fourth stopper 425 is provided between the housing 10 and the heat sink 42. The fourth stopper 425 is provided at an interval from the third edge 4222 of the heat dissipation fins 422, and a space for flowing the hot air flowing out from the third air outlet K4 is formed therebetween. Optionally, an FPC may be provided on the surface of the fourth stopper 425, and a circuit board may be provided on one side of the fourth stopper 425 close to the air flow generator, whereby the circuit board and the electrical components located at the curved portion of the housing 10, such as the hair removal assembly 20, the cooling sensation assembly 30, the skin care assembly, etc., are electrically connected via the FPC. The fourth stopper 425 can prevent the hot air flow from directly blowing onto the circuit board and can play a role in reducing the temperature of the circuit board to a certain extent. Optionally, there is an opening communicating with the aforementioned space between the fourth stopper 425 and the heat sink 42.
[0070] Optionally, the heat conduction member 60 is provided in a plate shape. One end thereof extends to the heat sink 42 and is covered above it, and the other end extends to the cooling sensation assembly 30 and contacts the heating surface of the semiconductor cooling sheet 31. The hair removal assembly 20 is located between the heat sink 42 and the cooling sensation assembly 30. The heat generated by the semiconductor cooling sheet 31 is conducted to the heat sink 42 through the heat conduction member 60, and then dissipated to the outside of the housing 10 through the heat sink 42. Further, since the fourth stopper 425 is located between the housing 10 and the heat conduction member 60, it can also function as a heat insulator to reduce the heat conduction from the heat sink 42 to the housing 10. Optionally, the heat conduction member 60 may be a vapor chamber.
[0071] In addition, in each of the above embodiments, the first stopper 421, the second stopper 423, the third stopper 424, and the fourth stopper 425 may all be part of the heat sink 42, part of the housing 10, or even separate members, and those skilled in the art can design them according to the actual situation.
[0072] In some embodiments, referring to FIGS. 4 and 5, between the air inlet hole 13 and the air outlet hole 12, a partition member 50 is provided for partitioning the spaces where the air inlet hole 13 and the air outlet hole 12 are respectively located.
[0073] In this embodiment, in order to further enhance the heat dissipation effect, between the air inlet hole 13 and the air outlet hole 12, a partition member 50 is provided for partitioning the spaces where the air inlet hole 13 and the air outlet hole 12 are respectively located. In this way, the hot air flow after heat exchange does not flow back into the internal space of the housing 10 where the air inlet hole 13 is located, and is basically discharged to the outside only from the air outlet hole 12. Optionally, the partition member 50 includes a convex plate protruding from the inside of the housing 10. One end of the convex plate is connected to the inner wall of the housing 10, and the other end abuts against the air flow generating device. The air inlet hole 13 and the air outlet hole 12 are respectively located on both sides of the convex plate.
[0074] In some embodiments, referring to FIGS. 1 to 3, the air inlet K2 and the second air outlet K3 are respectively located on both sides of the first air outlet K1, and the air flow generating device is provided at an angle with respect to the heat sink 42.
[0075] In this embodiment, the housing 10 includes a care head 15. The air flow generating device and the heat sink 42 are docked at the position of the care head 15. The air inlet K2 of the heat sink 42 is provided to form an angle with respect to the first air outlet K1 of the heat sink 42, adapting to the structural design of the care head 15. To enhance the heat dissipation effect of the beauty device, the air flow generating device is provided to form an angle with respect to the heat sink 42. When the air flow generating device is provided to form an angle with respect to the heat sink 42, each stopper of the heat sink 42 serves to guide the air flow, and most of the air flow can be guided to the first air outlet K1 and flow out from the air discharge hole 12 of the housing 10. Compared with the design where the air flow generating device is at the same height as the heat sink 42, the air flow resistance is smaller and its heat dissipation efficiency is higher, so heat can be discharged more efficiently and quickly.
[0076] The embodiment of this application provides another beauty device. Referring to FIGS. 1, 2, 8 to 15, the beauty device includes at least a housing 10, a beauty assembly, and a heat dissipation assembly. The housing 10 is provided with an air inlet hole 13 and an air discharge hole 12. Inside the housing 10, a first gas flow path 16 and a cavity 18 that communicate with each other are provided. The beauty assembly is provided inside the housing 10 and located in the first gas flow path 16, and includes a lamp 21 and a reflector 22 provided around the lamp 21. The reflector 22 is provided to be open on both opposite sides in the gas flow direction of the first gas flow path 16 to allow gas to pass through, and a second opening 22a is provided on or one side of the reflector 22. The heat dissipation assembly is provided inside the housing 10 and includes an air flow generating device. Here, the air inlet of the air flow generating device communicates with the air inlet hole 13, the air outlet of the air flow generating device communicates with the gas injection port 16a at one end of the first gas flow path 16, the gas discharge port 16b at the other end of the first gas flow path 16 communicates with the air discharge hole 12, a first opening 16c is provided on one side wall of the first gas flow path 16, the cavity 18 communicates with the space surrounded by the reflector 22 through the first opening 16c and the second opening 22a, and a third opening 18a is formed in the cavity 18, and the third opening 18a communicates with the air discharge hole 12.
[0077] In this embodiment, as shown in FIG. 11, the interior of the housing 10 is provided in a hollow shape and includes an upper housing and a lower cover. The upper housing and the lower cover are surrounded to form a receiving cavity for receiving the beauty assembly and the heat dissipation assembly. Here, the beauty assembly is used to care for the surface of the human skin and generates heat inside the housing 10 during operation, and the heat dissipation assembly is used to discharge the heat inside the housing 10 to the outside to prevent the housing 10 from generating heat due to heat concentration.
[0078] Optionally, the beauty device proposed in the embodiments of the present application may be a laser hair removal device, a skin rejuvenation device, a whitening device, an ultrasonic beauty device, etc., but is not limited thereto, and those skilled in the art can set it according to the actual situation. Correspondingly, the beauty assembly includes an electrode assembly, an LED assembly, and an ultrasonic assembly. Hereinafter, taking the hair removal device as an example, the technical solutions proposed in the embodiments of the present application will be described. At this time, as shown in FIGS. 2, 12, and 14, the beauty assembly may include a hair removal assembly 20, and a cooling assembly 30 may be correspondingly installed. The hair removal assembly 20 may include a lamp 21 and a reflector 22. The reflector 22 is provided around the lamp 21. The reflector 22 may be in an arc shape and may be provided to surround the lamp 21. A first light emitting port 11 may be opened in the housing 10. The lamp 21 of the hair removal assembly 20 is used to emit light. The light emitted to the first light emitting port 11 is received by the cooling assembly 30 and irradiated on the human skin to remove hair from the skin. When the human skin is irradiated with light, it receives light energy and converts it into internal energy to generate heat. In order to improve the user experience, the cooling assembly 30 may be brought into contact with the human skin. Since the surface temperature of the cooling assembly 30 is low, it can reduce the heat sensation of the human body when in contact with the human body. Optionally, the housing 10 may be provided substantially in a strip shape. The first light emitting port 11 may be located at one end of the housing 10. The air inlet hole 13 and the air outlet hole 12 may be located on one side of the housing 10.
[0079] The heat dissipation assembly includes an air flow generating device, which generates cooling air to dissipate heat from the beauty assembly. Optionally, the air flow generating device may include a fan. Here, as shown in FIGS. 12 to 14, the housing 10 is provided with an air inlet hole 13 for allowing outside air to enter the interior of the housing 10. The housing 10 is provided with a first gas flow path 16. The beauty assembly is located in the first gas flow path 16. Both ends of the first gas flow path 16 are a gas inlet 16a and a gas outlet 16b, respectively. The gas inlet 16a communicates with the air flow generating device, and the gas outlet 16b communicates with an air discharge hole 12 on the housing 10. Further, a first opening 16c is provided on one side wall of the first gas flow path 16. A cavity 18 is further provided in the housing 10. The cavity 18 communicates with the space surrounded by the reflector 22 through the first opening 16c and a second opening 22a provided above or on one side of the reflector 22, that is, communicates with the first gas flow path 16. The cavity 18 communicates with the air discharge hole 12.
[0080] That is, the reflector 22 may be provided with a second opening 22a, or the second opening 22a may not be provided on the reflector 22 and may be located on one side of the reflector 22. In order to achieve the purpose that the space surrounded by the reflector 22 communicates with the cavity 18, the second opening 22a is provided at a distance from other structures or members in the housing 10 by the reflector 22. Here, the shape of the second opening 22a may be elongated, wavy, etc., and can be set according to the actual situation and is not limited here. As can be easily understood, the cavity 18 and the first gas flow path 16 communicate substantially through the first opening 16c structurally, and the reflector 22 shields the first opening 16c in the first gas flow path 16, so that the cavity 18 communicates with the space surrounded by the reflector 22 through the second opening 22a provided above the reflector 22 or on one side of the reflector 22. The reflector 22 is provided at a distance from the first opening 16c, and the second opening 22a is correspondingly provided in the vicinity of the first opening 16c, so that the cavity 18 can be set to communicate with the space surrounded by the reflector 22 through the first opening 16c and the second opening 22a.
[0081] Specifically, the beauty assembly of the beauty device generates heat during operation. The airflow generator of the heat dissipation assembly sucks in gas at its air inlet, generates cooling air, and sends it into the first gas flow path 16 from the gas injection port 16a of the first gas flow path 16 at its air outlet. After heat exchange with the beauty assembly, hot air is formed. A part of it still flows along the first gas flow path 16 and flows out from the gas outlet 16b of the first gas flow path 16 to the air discharge hole 12 and is discharged. Another part flows into the cavity 18 from the second opening 22a on the reflector 22 and the first opening 16c of the first gas flow path 16, flows along the cavity 18, and flows out from the cavity 18 to the air discharge hole 12 and is discharged. In the beauty device of the present application, the exhaust and heat dissipation of multiple passages of the beauty assembly can be realized, the heat dissipation speed can be increased, the concentration of heat can be prevented, the heat dissipation effect of the beauty device can be further improved, and local overheating of the beauty device can be prevented.
[0082] In some embodiments, referring to FIGS. 12 and 14, the beauty assembly further includes a light filter 51, which is provided opposite to the reflector 22 and is used to filter the light emitted from the lamp 21. The edge of the reflector 22 facing the light filter 51 is provided to be missing to form a second opening 22a, or the distance between the edge of the reflector 22 facing the light filter 51 and the light filter 51 forms the second opening 22a.
[0083] Here, a cooling assembly 30 and a beauty assembly are respectively provided on the front side and the rear side of the light filter 51. The light filter 51 includes a filter film. Considering that the filter film may be damaged if the temperature of the light filter 51 is too high, in this embodiment, the second opening 22a is provided at the edge of the reflector 22 facing the light filter 51, or the reflector 22 and the light filter 51 are provided at a distance from each other, and the distance between them forms the second opening 22a. Hot air is discharged from the second opening 22a, thereby contributing to promoting the discharge of the air flow near the light filter 51, reducing the heat on the side of the light filter 51 facing the beauty assembly, avoiding the temperature of the light filter 51 from being too high. Also, since the hot air can be discharged from the second opening 22a, the heat dissipation efficiency at the light filter 51 is improved, the heat radiated toward the cooling assembly 30 is reduced, which is advantageous for ensuring the cooling effect of the beauty device.
[0084] In some embodiments, referring to FIGS. 12 and 14, the second opening 22a is provided to extend toward both opposite sides of the reflector 22. Here, the second opening 22a is in a long shape and is provided to extend toward both opposite sides of the reflector 22, so as to maximize the ventilation area of the second opening 22a without light leakage, increase the flow of the gas flowing from the second opening 22a in the first gas flow path 16 into the cavity 18, and help improve the heat dissipation effect.
[0085] In some embodiments, referring to FIGS. 11 to 14, the beauty device further includes a central frame 10B, the central frame 10B is located within the housing 10, the first gas flow path 16 is formed in the central frame 10B, and the gas inlet 16a and the gas outlet 16b of the first gas flow path 16 are respectively located at opposite ends of the central frame 10B. The air flow generating device is provided opposite to the central frame 10B and is docked to one end having the gas inlet 16a of the central frame 10B.
[0086] Specifically, the central frame 10B is accommodated within the accommodation cavity of the housing 10. The central frame 10B may be a separate member or may be integrally formed with the housing 10 as a part of the housing 10. Further, when the central frame 10B is a separate member, the central frame 10B may be detachably provided in the housing 10. The forms of detachable provision may include engagement installation, screw connection, etc. The first gas flow path 16 is formed in the central frame 10B, and the beauty assembly is attached to the central frame 10B and provided within the first gas flow path 16. Here, the central frame 10B may have various outer shapes such as a U-shaped structure, an L-shaped structure, etc., and is set according to the actual situation.
[0087] In some embodiments, referring to FIGS. 12 to 15, the beauty device further includes a baffle 90. The baffle 90 is located within the housing 10 and is provided corresponding to the central frame 10B, so that a cavity 18 is formed therebetween. The first opening 16c and the third opening 18a are respectively located in the direction of both ends of the cavity 18.
[0088] Here, a concave space is provided in the central frame 10B, and the baffle 90 is provided opposite to the central frame 10B so as to cover the concave space of the central frame 10B, and further forms a cavity 18 between the baffle 90 and the central frame 10B. Here, the baffle 90 may be a separate member, the baffle 90 may be detachably connected to the central frame 10B, or the baffle 90 may be integrally formed with the central frame 10B, which can be set according to the actual situation. The gas in the first gas flow path 16 passes through the second opening 22a and the first opening 16c and flows into the cavity 18, and then is blocked by the baffle 90, and further flows along the cavity 18, flows out from the third opening 18a of the cavity 18, and flows into the air discharge hole 12.
[0089] As can be easily understood, by forming the cavity 18 between the baffle 90 and the central frame 10B, the flow direction of the gas flowing out from the second opening 22a in the first gas flow path 16 changes correspondingly, that is, the gas flowing out from the second opening 22a in the first gas flow path 16 flows along the cavity 18 and flows out from the air discharge hole 12, and the situation of flowing out from the air discharge hole 12 and scalding the user is avoided.
[0090] In some embodiments, referring to FIGS. 8, 11 and 15, the heat dissipation assembly further includes a heat sink 42, the central frame 10B and the air flow generating device are provided surrounding the heat sink 42, and the opposite ends of the central frame 10B are positioned corresponding to the opposite sides of the heat sink 42. The heat sink 42 has an air inlet K2 docked to the air outlet of the air flow generating device and a first air outlet K1 leading to the air discharge hole 12.
[0091] Specifically, the heat sink 42 is used to dissipate heat from the internal devices of the beauty device. For example, the heat sink 42 is connected to the heat conduction plate of the cooling assembly 30, and the heat generated by the heating element of the cooling assembly 30 is conducted to the heat sink 42 through the heat conduction plate for heat dissipation. The heat sink 42 has an air inlet K2 and a first air outlet K1. The air inlet K2 is docked to the air outlet of the air flow generating device to allow the cooling air generated by the air flow generating device to flow into the heat sink 42 from there for heat exchange. The first air outlet K1 is provided towards the air discharge hole 12 on the housing 10 to discharge the hot air after heat exchange from there to the outside of the housing 10.
[0092] In some embodiments, referring to FIGS. 13 to 15, the gas outlet 16b is provided towards the heat sink 42 and is located on different side directions of the heat sink 42 from the air discharge hole 12. One end of the central frame 10B where the gas outlet 16b is provided is provided at a distance from the heat sink 42 to form a gas passage 17. The gas passage 17 is used to allow the gas flowing out from the gas outlet 16b to pass through and flow to the air discharge hole 12.
[0093] Specifically, the beauty assembly generates heat during operation. The air flow generating device of the heat dissipation assembly sucks gas from the air inlet hole 13 at its air inlet, generates cooling air, and sends it into the first gas flow path 16 from the gas injection port 16a of the first gas flow path 16 at its air outlet. After heat exchange in the beauty assembly, hot air is formed, flows out from the gas outlet 16b, passes through the gas passage 17 between the central frame 10B and the heat sink 42, and flows to the air discharge hole 12 for discharge. Thereby, it can be prevented that the hot air is directly blown onto the heat sink 42 and affects its heat dissipation effect.
[0094] In some embodiments, the portion of the central frame 10B located between the gas outlet 16b and the gas inlet 16a is provided at a distance from the heat sink 42 to form a gas movement passage 19. The heat sink 42 further includes a second air outlet K3 facing the central frame 10B, and the second air outlet K3 communicates with the air discharge hole 12 through the gas movement passage 19.
[0095] Specifically, the heat sink 42 further includes a second air outlet K3. The second air outlet K3 faces the central frame 10B and has the same function as the first air outlet K1. It is used to discharge the hot air after heat exchange in the heat sink 42. By exhausting air from multiple air outlets to dissipate heat, the heat dissipation rate is increased. Furthermore, the hot air discharged from the second air outlet K3 of the heat sink 42 enters the gas movement passage 19 and flows along the gas movement passage 19 to the air discharge hole 12 and is discharged.
[0096] In some embodiments, referring to FIGS. 8, 14, and 15, the third opening 18a is provided facing the heat sink 42, communicates with the gas movement passage 19, and is offset from the second air outlet K3 in the moving direction of the gas movement passage 19. On both sides of the third opening 18a, an air flow low-pressure side and an air flow high-pressure side are respectively formed. At least a part of the gas flowing out from the second air outlet K3 passes through the gas movement passage 19 and flows into the cavity 18 from the air flow low-pressure side of the third opening 18a. At least a part of the gas in the cavity 18 flows out from the air flow high-pressure side of the third opening 18a, passes through the gas movement passage 19, and flows to the air discharge hole 12.
[0097] The beauty assembly generates heat during operation. The airflow generator of the heat dissipation assembly sucks in gas at its air inlet, generates cooling air, and sends it into the first gas flow path 16 from the gas injection port 16a of the first gas flow path 16 at its air outlet. It exchanges heat with the beauty assembly to form hot air. A part of the hot air flows into the cavity 18 from the second opening 22a and the first opening 16c, flows out from the third opening 18a of the cavity 18, passes through the gas movement passage 19 between the central frame 10B and the heat sink 42, flows to the air discharge hole 12, and is discharged, preventing the hot air from directly blowing out onto the heat sink 42 and affecting its heat dissipation effect.
[0098] Furthermore, as can be easily understood, when the gas flowing along the first gas flow path 16 reaches one side of the beauty assembly and does not pass through the beauty assembly, it is low-temperature gas. Correspondingly, an airflow low-pressure side is formed on one side of the third opening 18a. When it passes through the beauty assembly and reaches the other side of the beauty assembly, it becomes high-temperature gas by absorbing the heat of the beauty assembly. Correspondingly, an airflow high-pressure side is formed on the other side of the third opening 18a.
[0099] The second air outlet K3 and the third opening 18a are provided offset in the moving direction of the gas movement passage 19. Furthermore, the gas flowing out from the second air outlet K3 of the heat sink 42 passes through the third opening 18a when flowing along the gas movement passage 19. When the gas flowing out from the second air outlet K3 of the heat sink 42 passes through the third opening 18a, affected by the pressure of the airflow at the position of the third opening 18a, at least a part of the gas flows into the cavity 18 from the airflow low-pressure side of the third opening 18a correspondingly, and mixes with the gas flowing into the cavity 18 from the first opening 16c and the second opening 22a. There may also be another part of the gas that directly flows along the gas movement passage 19 to the air discharge hole 12 and is discharged.
[0100] At least a part of the gas in the cavity 18 flows out from the high-pressure side of the air flow of the third opening 18a, and there may be another part of the gas that flows out from the low-pressure side of the air flow of the third opening 18a. All of these gases continuously flow through the gas transfer passage 19 and are discharged through the air discharge hole 12.
[0101] In some embodiments, referring to FIG. 11, the heat dissipation assembly further includes a mounting housing 43. The air flow generating device is provided in the mounting housing 43, and a flow dividing member 80 is provided at the air discharge port of the mounting housing 43 close to the air flow generating device. The flow dividing member 80 is used to guide the cooling air generated by the air flow generating device to the first gas flow path 16 and the heat sink 42 respectively.
[0102] That is, during the operation of the beauty device, the cooling air generated by the air flow generating device of the heat dissipation assembly is divided into two parts by the flow dividing member 80 at its air discharge port. A part of the cooling air enters the first gas flow path 16 from the gas injection port 16a of the first gas flow path 16, exchanges heat with the beauty assembly to form hot air, and flows from the gas discharge port 16b to the air discharge hole 12 and is discharged. Another part of the cooling air enters the interior of the heat sink 42 from the air inlet K2 of the heat sink 42, exchanges heat to form hot air, and flows from the first air discharge port K1 to the air discharge hole 12 and is discharged.
[0103] Yet another embodiment of the present application provides a beauty device. Referring to FIGS. 1, 2, 11, 13 to 16, the beauty device at least includes a housing 10, a beauty assembly, and a heat dissipation assembly. The housing 10 is provided with an air inlet hole 13 and an air outlet hole 12. A first gas flow path 16 is provided inside the housing 10. The beauty assembly is provided inside the housing 10 and located within the first gas flow path 16. The heat dissipation assembly is provided inside the housing 10 and includes an air flow generating device (not shown). The air inlet of the air flow generating device communicates with the air inlet hole 13, the air outlet of the air flow generating device communicates with a gas injection port 16a at one end of the first gas flow path 16, the gas discharge port 16b at the other end of the first gas flow path 16 communicates with the air outlet hole 12, and an air guide structure 161 is provided inside the first gas flow path 16. The air guide structure 161 guides the flow direction of the gas in the first gas flow path 16, allowing the gas to pass through multiple locations of the gas discharge port 16b and flow out through the air outlet hole 12.
[0104] Here, the flow direction of the gas in the first gas flow path 16 is different from the discharge direction of the gas discharge port 16b. An air guide structure 161 is provided inside the first gas flow path 16. The air guide structure 161 is provided corresponding to the position of the gas discharge port 16b and is used to guide the gas to flow to the gas discharge port 16b in the first gas flow path 16 and discharge the gas uniformly from the gas discharge port 16b to the air outlet hole 12. Specifically, when the gas reaches one end of the first gas flow path 16 where the gas discharge port 16b is located, the flow direction is changed under the guidance of the air guide structure 161, passing through multiple locations of the gas discharge port 16b and flowing out through the air outlet hole 12, realizing uniform outflow of the gas in the first gas flow path 16, avoiding heat concentration, further enhancing the heat dissipation effect of the beauty device, and preventing local overheating of the beauty device.
[0105] Here, the air guide structure 161 can be configured in various forms.
[0106] In some embodiments, as shown in FIG. 13, the air guide structure 161 is provided on one inner wall of the first gas flow path 16 and extends toward the other opposing inner wall of the first gas flow path 16. Here, in the gas flow direction in the first gas flow path 16, the distance between the air guide structure 161 and the other opposing inner wall of the first gas flow path 16 gradually decreases, and by gradually blocking the gas flowing at different heights in the first gas flow path 16, the gas is uniformly guided to multiple locations of the gas discharge port 16b.
[0107] Specifically, when the gas flows through the first gas flow path 16 and reaches one end where the gas discharge port 16b is located, the air guide structure 161 blocks the gas and changes its flow direction. Here, since the distance between the air guide structure 161 and the other opposing inner wall of the first gas flow path 16 gradually decreases, the gas flowing through different locations in the first gas flow path 16 is gradually blocked by the air guide structure 161, and its flow direction is further changed and guided to different locations corresponding to the gas discharge port 16b. Optionally, the gas flows horizontally in the first gas flow path 16, and the gas flowing at different heights is changed to flow vertically by being blocked by the air guide structure 161.
[0108] Optionally, the air guide structure 161 may be an entire protruding inclined surface or arc surface, which is set according to the actual situation.
[0109] In some embodiments, as shown in FIGS. 14 and 16, the air guide structure 161 includes an air guide portion 1610. The air guide portion 1610 is stepped to form a plurality of first air guide surfaces 1611, and the plurality of first air guide surfaces 1611 correspondingly block the gas flowing at different heights in the first gas flow path 16.
[0110] Specifically, the air guide structure 161 adopts a structural form of a stepped air guide portion 1610. Further, in the flow direction of the gas in the first gas flow path 16 toward the air discharge hole 12, the distance between the air guide structure 161 and the other opposing inner wall of the first gas flow path 16 gradually decreases. When the gas flows through the first gas flow path 16 and reaches the air guide portion 1610, it is blocked by the first air guide surface 1611 of the air guide portion 1610, and the flow direction is changed, and it is guided to the gas discharge port 16b.
[0111] Here, the plurality of first air guide surfaces 1611 correspond to the plurality of stepped surfaces of the stepped air guide portion 1610. The plurality of first air guide surfaces 1611 on the air guide portion 1610 correspondingly block the gas flowing through different locations in the first gas flow path 16, and guide the gas flowing through different locations in the first gas flow path 16 to different locations of the gas discharge port 16b correspondingly.
[0112] Optionally, the first air guide surface 1611 is an inclined surface, an arc surface or an uneven surface. Here, when the first air guide surface 1611 is an inclined surface, the inclination degree is set according to the actual situation. When the first air guide surface 1611 is an arc surface, the radian is set according to the actual situation. When the first air guide surface 1611 is an uneven surface, it may be a surface with protrusions or recesses, for example, a surface formed with saw teeth, saw blades, bumps, etc. The uneven shape is set according to the actual situation.
[0113] In some embodiments, a second air guide surface 1612 is further formed on the air guide portion 1610. Between any two adjacent first air guide surfaces 1611, they are connected by the second air guide surface 1612. The second air guide surface 1612 guides the flow direction of the gas that has been blocked by the first air guide surface 1611 and flows backward, and makes the gas flow to the gas discharge port 16b.
[0114] Specifically, the gas flows through the first gas flow path 16. When it reaches the air guide portion 1610, it is blocked by the first air guide surface 1611 of the air guide portion 1610, and its flow direction is changed and dispersed. A part of it flows backward, and another part flows toward the gas discharge port 16b and further flows into the gas discharge port 16b. Here, a part of the gas that is blocked by the first air guide surface 1611 and flows backward may flow along the second air guide surface 1612. The second air guide surface 1612 guides the flow direction of a part of the gas, causing that part of the gas to flow toward the gas discharge port 16b and further flow into the gas discharge port 16b.
[0115] Furthermore, the provided second air guide surface 1612 guides the flow direction of the gas flowing backward so that it flows into the gas discharge port 16b. Thereby, the exhaust of the notch portion between the two air discharge positions at the gas discharge port 16b corresponding to the two adjacent first air guide surfaces 1611 is compensated, and the exhaust of the gas discharge port 16b can be made more uniform.
[0116] That is, since multiple stages of air guide surfaces are provided in the gas flow direction, when the gas passes through each air guide surface, a part of it flows out toward the gas discharge port 16b on the air guide surface, avoiding the concentration of all the gas at the end of the first gas flow path 16, and the effect of dispersing and discharging the gas can be realized.
[0117] Optionally, the second air guide surface 1612 is an arc surface. Here, the radian of the second air guide surface 1612 is set according to the actual situation. Otherwise, the second air guide surface 1612 may further be a V-shaped surface, an inclined surface, an uneven surface, or the like.
[0118] In some embodiments, the gas discharge port 16b and the air guide structure 161 are respectively located on two adjacent inner walls or opposite inner walls of the first gas flow path 16.
[0119] In an actual setting, as shown in FIGS. 13 and 14, the gas outlet 16b and the air guide structure 161 are respectively located on two adjacent inner walls of the first gas flow path 16, and the air guide structure 161 corresponds to the position of the gas outlet 16b. Alternatively, the gas outlet 16b and the air guide structure 161 may be respectively located on two opposing inner walls of the first gas flow path 16, and the air guide structure 161 may be set to face the position of the gas outlet 16b.
[0120] In some embodiments, the beauty device further includes a central frame 10B. The central frame 10B is located within the housing 10. The first gas flow path 16 is formed in the central frame 10B. The gas inlet 16a and the gas outlet 16b of the first gas flow path 16 are respectively located at two opposing ends of the central frame 10B. The air flow generating device is provided facing the central frame 10B and is docked at one end having the gas inlet 16a of the central frame 10B.
[0121] In some embodiments, as shown in FIGS. 11 and 15, the heat dissipation assembly further includes a heat sink 42. The central frame 10B and the air flow generating device are provided surrounding the heat sink 42. Two opposing ends of the central frame 10B are respectively located corresponding to two opposing sides of the heat sink 42. The heat sink 42 has an air inlet K2 docked to the air outlet of the air flow generating device and a first air outlet K1 leading to the air discharge hole 12.
[0122] Optionally, the central frame 10B presents a U-shaped structure such that an accommodation space is formed outside thereof. The heat sink 42 is located in the accommodation space outside the central frame 10B. The central frame 10B and the air flow generating device are provided surrounding the heat sink 42, with a compact structure and a small internal space occupied in the housing 10.
[0123] In some embodiments, as shown in FIG. 15, the gas outlet 16b is provided facing the heat sink 42 and is located on a different side direction of the heat sink 42 from the air discharge hole 12. One end having the gas outlet 16b of the central frame 10B is provided at a distance from the heat sink 42 to form a gas passage 17, and the gas passage 17 is used to allow the gas flowing out from the gas outlet 16b to pass through and flow to the air discharge hole 12.
[0124] Referring to FIGS. 1, 17 to 21, the beauty device proposed in a further embodiment of the present application is a housing 10, a light source 2 provided in the housing 10, a cooling assembly 30 provided on one side in the light emitting direction of the light source 2 and used to guide light to human skin for skin care, a first optical element 4 provided between the light source 2 and the cooling assembly 30, a second optical element 5 provided between the first optical element 4 and the cooling assembly 30, a first sealing member 6 provided between the first optical element 4 and the second optical element 5, the first sealing member 6 being used to seal the gap between the first optical element 4 and the second optical element 5.
[0125] The beauty device proposed in the embodiments of the present application may be a hair remover, a skin rejuvenator, a whitening device, etc. Hereinafter, taking the hair remover as an example, the technical solutions proposed in the embodiments of the present application will be described. Specifically, the first optical element 4 and the second optical element 5 of this embodiment are excellent in light transmissibility and heat resistance, and may be a quartz plate or glass. Optionally, one of the first optical element 4 and the second optical element 5 is a light filter 51, and the light filter 51 is used to filter light, and the other of the first optical element 4 and the second optical element 5 is a heat shield sheet 41, and the heat shield sheet 41 is used to block the heat radiated from the light source 2 to the cooling assembly 30. In this embodiment, the first optical element 4 is the heat shield sheet 41, and the second optical element 5 is the light filter 51. In this embodiment, an attachment structure for attaching the light source 2, the cooling assembly 30, the light filter 51 and the heat shield sheet 41 is provided inside the housing 10. The housing 10 may include an upper cover and a lower housing, and the upper cover and the lower housing surround to form the attachment structure for attaching the light source 2, the light filter 51, the heat shield sheet 41 and the cooling assembly 30 therein. Here, the housing 10 has an open end, and the cooling assembly 30 is provided at the open end of the housing 10 and is used to contact the human skin to give a cooling sensation and reduce the skin temperature. The light source 2 of this embodiment is used to provide intense pulsed light or laser for skin care. Optionally, the light source 2 may be a lamp 21, and a reflector 22 is provided on one side of the lamp 21. The reflector 22 partially surrounds the lamp 21 and has an opening facing the cooling assembly 30. The lamp 21 is provided along the width direction of the housing, and the lamp 21 may be a laser lamp, a xenon lamp, an LED lamp, etc.
[0126] In this embodiment, the heat insulation sheet 41 is provided between the light source 2 and the cooling assembly 30, and the optical filter 51 is provided between the heat insulation sheet 41 and the cooling assembly 30. Here, the optical filter 51 is used to filter the light passing through. Specifically, the light emitted from the light source 2 may be strong pulsed light. In this case, the strong pulsed light is polychromatic light including light of different wavelengths, among which the ultraviolet light with a wavelength of 400 nm or less is included. The ultraviolet light is harmful to human skin and eyes. The optical filter 51 of this embodiment can filter the harmful light of this wavelength and retain the light of a wavelength suitable for hair removal and beauty. The optical filter 51 is excellent in light transmittance and heat resistance. Optionally, the optical filter 51 is a quartz plate. The heat insulation sheet 41 can block the heat radiated by the light source 2 and reduce the heat radiated to the cooling assembly 30. Further, since the heat insulation sheet 41 is provided between the light source 2 and the optical filter 51, it can also protect the optical filter 51 and reduce the risk that the filter layer on the optical filter 51 peels off or is damaged due to the optical filter 51 getting too hot. The heat insulation sheet 41 may be a transparent low thermal conductivity material such as glass. The cooling assembly 30 of this embodiment is used to guide the strong pulsed light to the human skin. The strong pulsed light acts on the hair follicles of the skin to change the structure of the hair follicles, thereby achieving the hair removal effect. During hair removal, the cooling assembly 30 contacts the human skin to give a cooling sensation and reduce the burning sensation generated from the skin during hair removal. Further, the heat insulation sheet 41 is provided between the cooling assembly 30 and the light source 2, blocking the heat radiated from the light source 2, thereby greatly reducing the heat radiated to the cooling assembly 30, improving the cooling effect of the cooling assembly on the skin, reducing the burning sensation generated during hair removal, and improving the user experience. In some embodiments, the cooling assembly 30 includes a lens 32 for contacting the human skin and a semiconductor cooling sheet 31. The cooling surface of the semiconductor cooling sheet 31 contacts the lens 32 to lower the temperature of the lens 32. The lens 32 may be sapphire. Sapphire can contact the skin during hair removal to lower the temperature of the skin surface and further reduce the burning sensation of the skin.
[0127] During the operation of the cooling assembly 30, since the temperature of the lens 32 of the cooling assembly 30 is low and the temperature around the internal light source 2 of the housing 10 is high, fogging is likely to occur on one end face of the lens 32 close to the light source. In contrast, referring to FIGS. 17 to 21, the first sealing member 6 is provided between the first optical element 4 and the second optical element 5, seals the gap between the first optical element 4 and the second optical element 5, and further, as shown in FIG. 18, the second optical element 5 is provided in close contact with the cooling assembly 30.
[0128] Specifically, the first optical element 4 is a heat insulating sheet 41, and the second optical element 5 is an optical filter 51. The heat insulating sheet 41 partitions the interior of the housing 10 into a first space for mounting the light source 2 and a second space for mounting the cooling assembly 30, thereby blocking heat from the second space. In order to prevent hot air from entering the second space and contacting the low-temperature lens 32 to cause fogging, in this embodiment, the first sealing member 6 is used to seal the second space. Specifically, the first sealing member 6 seals the gap between the heat insulating sheet 41 and the optical filter 51 to prevent the intrusion of external hot air. At the same time, since the optical filter 51 is provided in close contact with the lens 32, the external cold air flow generated by the cooling assembly 30 can be blocked, the fogging phenomenon of the lens 32 and the optical elements in the gap can be avoided, and the service life and performance of the depilator are improved.
[0129] In another embodiment, referring to FIG. 19, the first optical element 4 is provided at a distance from the second optical element 5, the second optical element 5 is provided at a distance from the cooling assembly 30, a first sealing member 6 is provided between the first optical element 4 and the second optical element 5, and a second sealing member 7 is provided between the second optical element 5 and the cooling assembly 30. That is, the optical filter 51 is provided at a distance from the lens 32 and the heat insulating sheet 41 respectively. The first sealing member 6 seals the gap between the heat insulating sheet 41 and the optical filter 51, and the second sealing member 7 seals the gap between the optical filter 51 and the lens 32, thereby ensuring that external hot air does not enter the space between the heat insulating sheet 41 and the lens 32.
[0130] In some embodiments, referring to FIGS. 20 and 21, an attachment structure for attaching the heat insulation sheet 41 and the optical filter 51 is provided in the housing 10. Optionally, the housing 10 includes a central frame 10B, and a first stepped portion 11B is provided in the central frame 10B. The first stepped portion 11B is provided on one side facing the light source 2 of the cooling assembly 30. The edge of the heat insulation sheet 41 is provided in the first stepped portion 11B and partitions the internal space of the central frame 10B into a first space for attaching the light source 2 and a second space for attaching the cooling assembly 30, thereby blocking the heat radiated from the light source 2 in the first space from the second space and reducing the influence of the heat of the light source 2 on the cooling assembly 30 in the second space. Optionally, the cross section of the heat insulation sheet 41 is larger than that of the cooling assembly 30. When the heat insulation sheet 41 is provided in the first stepped portion 11B, it completely covers the cooling assembly 30 to block the heat radiated from the light source.
[0131] Optionally, a second stepped portion 12B is further formed in the central frame 10B of the housing 10. The second stepped portion 12B is provided on one side of the heat insulation sheet 41 facing the cooling assembly 30. The second stepped portion 12B of this embodiment has a groove structure, and the groove of the second stepped portion 12B restricts and fixes the optical filter 51 according to the shape and size of the optical filter 51.
[0132] Optionally, the heat insulation sheet 41 of this embodiment is attached to the first step portion 11B by the first seal member 6. The first seal member 6 is provided in a square ring shape. One side of the first seal member 6 facing the cooling assembly 30 is in close contact with both the first step portion 11B and the end face of the optical filter 51. On the other side facing away from the cooling assembly 30, a third step portion 61 is formed, and the edge portion of the heat insulation sheet 41 is provided on the third step portion 61. The third step portion 61 has a groove adapted to the shape and size of the heat insulation sheet 41, thereby restricting and fixing the heat insulation sheet 41. The first seal member 6 of this embodiment has elasticity and has a buffering effect capable of protecting the optical filter 51 and the heat insulation sheet 41 from the influence of the external environment, and has the greatest degree of protecting the optical element close to the lens 32. For example, when the hair remover collides, since the first seal member 6 has elasticity and has a buffering effect on the optical filter 51 and the heat insulation sheet 41, a rigid body collision between the optical filter 51 and the cooling assembly 30 is avoided, and the optical filter 51 and the heat insulation sheet 41 are protected.
[0133] In some embodiments, the projection area of the cooling assembly 30 in the light emitting direction is reduced within the projection area of the second optical element 5 in the light emitting direction, and the projection area of the second optical element 5 in the light emitting direction is reduced within the projection area of the first optical element 4 in the light emitting direction. That is, the cross-sectional areas of the cooling assembly 30, the second optical element 5, and the first optical element 4 increase sequentially so that the light passing through the cooling assembly is not blocked by the first optical element 4 and the second optical element 5.
[0134] Continuing to refer to FIGS. 18 and 21, in some embodiments, in order to further reduce heat, a first gas flow path 16 is formed within the housing 10. The first gas flow path 16 is provided on the side of the heat insulation sheet 41 close to the light source 2, and the light source 2 is provided within the first gas flow path 16. The first gas flow path 16 is used to dissipate heat from the light source 2 and the heat insulation sheet 41. Specifically, the light source 2 is a lamp. The lamp is provided along the width direction of the housing 10 and is spaced apart in parallel with the heat insulation sheet 41. One side surface of the heat insulation sheet 41 forms one side wall of the first gas flow path 16. The lamp is provided at a certain distance from the bottom plate of the housing 10, and by suspending the lamp in the first gas flow path 16, it contributes to the heat dissipation of the lamp. Optionally, the first gas flow path 16 extends along the length direction of the lamp. Gas inlets 131 and gas outlets 132 are respectively provided at both ends of the first gas flow path 16. A fan (not shown) is provided at the gas inlet 131, and the gas outlet 132 communicates with the outside of the housing 10. The fan can blow out cooling air. The cooling air is blown into the first gas flow path 16 from the gas inlet 131, carries out the heat of the lamp and the heat insulation sheet 41 within the first gas flow path 16, and finally the heat dissipation air flow is discharged from the gas outlet 132 of the first gas flow path 16 to the outside of the housing 10, thereby completing the heat dissipation of the lamp and the heat insulation sheet 41 and lowering the temperatures of the lamp and the heat insulation sheet 41. Optionally, the edge of the reflector 22 facing the heat insulation sheet 41 is provided to be missing to form a second opening 211. The second opening 211 communicates with the first gas flow path 16. The second opening 211 is in a long shape and extends towards both opposite sides of the reflector 22. The cooling air is blown from the first gas flow path 16 into the heat insulation sheet 41 and is discharged from the second opening 221 to the outside of the housing 10, which helps to lower the heat on the side of the heat insulation sheet 41 facing the light source 2.
[0135] Continuing to refer to FIG. 18, in some embodiments, in order to further improve the user experience, the cooling assembly 30 includes a lens 32 for contacting the human skin and a semiconductor cooling sheet 31. The semiconductor cooling sheet 31 includes a cooling surface and a heating surface, and the cooling surface of the semiconductor cooling sheet 31 contacts the lens 32. The lens 32 may be sapphire. During operation, the cooling surface of the semiconductor cooling sheet 31 is in close contact with the lens 32, conducting the cold air flow to the lens 32. Since the lens 32 contacts the human body, the cold air flow is further conducted to the skin, giving a cold feeling to the skin, thereby reducing the burning sensation generated from the skin during hair removal and improving the user experience.
[0136] Since heat is generated by the cooling operation of the semiconductor cooling sheet 31, it is necessary to dissipate the heat of the semiconductor cooling sheet 31. Optionally, on one side away from the light emission direction of the light source 2, a heat sink 8 is provided. The heat sink 8 is connected to the heating surface of the semiconductor cooling sheet 31 through a heat conduction member 9. The heat sink 8 of this embodiment is used for dissipating the heat of the semiconductor cooling sheet 31. Specifically, a heat conduction member 9 is connected between the heat sink 8 and the semiconductor cooling sheet 31. One end of the heat conduction member 9 contacts the heating surface of the semiconductor cooling sheet 31, and the other end contacts the heat sink 8. The heat generated on the heating surface of the semiconductor cooling sheet 31 is conducted to the heat sink 8 through the heat conduction member 9, and the heat sink 8 transports the heat outside the housing 10 to complete the heat dissipation of the semiconductor cooling sheet 31.
[0137] Referring to FIGS. 22 to 29, a beauty device proposed in an embodiment of the present application includes a beauty device main body 1 and an accessory head 2B of the beauty device. The accessory head 2B of the beauty device is used in combination with the beauty device main body 1. The beauty device main body 1 may be the beauty device of the above embodiment. The beauty device main body 1 includes a housing 10. A first light emission port 11 is provided at one end of the housing 10, and a cooling assembly 30 is provided at one end of the beauty device main body 1.
[0138] The accessory head 2B of the beauty device is It is used for detachably connecting to the beauty device main body 1, and includes an outer cover 210 including a contact outer surface and a connection outer surface, a conductive member 22B provided on the outer cover 210, including a first end surface exposed on the contact outer surface and a second end surface exposed on the connection outer surface, wherein the first end surface is for contacting human skin, and the second end surface is for contacting the cooling assembly 30 when the outer cover 210 is connected to the beauty device main body 1. The conductive member 22B, an elastic member 22C provided between the outer cover 210 and the conductive member 22B, one end of which acts on the outer cover 210 and the other end acts on the conductive member 22B in the direction of the second end surface. Thereby, when the outer cover 210 is connected to the beauty device main body 1, the conductive member 22B is in close contact with the cooling assembly 30. The elastic member 22C,
[0139] The beauty device main body 1 of this embodiment is a beauty device that can be used alone for skin care, and specifically, it may be a hair remover. The beauty device main body 1 includes a handheld part 14, and the handheld part 14 is provided with a certain curvature, which conforms to ergonomics and facilitates the user's grasping. The beauty device main body 1 can emit light for skin care, and the light may be intense pulsed light or a laser. The laser or intense pulsed light can stimulate hair follicles without damaging normal skin tissue. The hair follicles absorb the energy of the light and change their structure, thus achieving the effect of hair removal. Optionally, the beauty device main body 1 includes a light source (not shown) that emits light, and the light source may be a laser lamp, a xenon lamp, an LED lamp, etc. The light emitted from the light source is emitted from the cold feeling assembly 30 at one end of the beauty device main body 1 to the skin for hair removal of the skin. When removing hair, when the light acts on the human skin, a slight burning sensation may occur on the skin. In some embodiments, the cold feeling assembly 30 includes a cold feeling member 121 and a semiconductor cooling sheet 31. The cold feeling member 121 may be a lens 32, and the semiconductor cooling sheet 31 includes a cooling surface and a heating surface. The cooling surface of the semiconductor cooling sheet 31 contacts the cold feeling member 121. During operation, the cooling surface of the semiconductor cooling sheet 31 is in close contact with the cold feeling member 121, conducting the generated cold air flow to the cold feeling member 121. Since the cold feeling member 121 contacts the human body, the cold air flow is further conducted to the skin, giving the skin a cold feeling, thereby reducing the burning sensation generated from the skin during hair removal and improving the user's experience. The cold feeling member 121 may be a lens such as sapphire with excellent thermal conductivity and heat dissipation. When the light passes through the sapphire, the sapphire can quickly absorb heat and transmit it to the outside of the hair remover. In this way, the sapphire can quickly cool the skin surface, suppress the transmission of heat to the deep part of the skin, and reduce the degree of the burning sensation.
[0140] As will be understood, in some other embodiments, the cooling member 121 may further be a light-impermeable structural member such as metal or ceramic. Specifically, the beauty device main body 1 further includes a first light-emitting port 11 that emits light, and the cooling member 121 is provided surrounding the light-emitting port. During the hair removal operation of the hair remover, the light-emitting port fits against the skin, and the light emitted from the light source is irradiated from the first light-emitting port 11 onto the human skin. The cooling member 121 calms the skin around the light-emitting port and reduces the burning sensation.
[0141] When it is necessary to depilate different parts of the body, it is usually necessary to use an accessory head. Since the depilator equipped with the accessory head is not provided with a cooling assembly on the accessory head, it is difficult for the cooling effect on the skin to meet the user's needs. In contrast, the accessory head 2B of the beauty device of this embodiment is provided with a conductive member 22B and an elastic member 22C. The conductive member 22B includes a first end face exposed on the contact outer surface of the outer cover 210 and a second end face exposed on the connection outer surface of the outer cover 210. The elastic member 22C makes the second end face of the conductive member 22B in close contact with the cooling member 121 of the cooling assembly 30. Specifically, the elastic member 22C is provided between the outer cover 210 and the conductive member 22B. When the accessory head 2B of the beauty device is connected to the beauty device main body 1, one end of the elastic member 22C acts on the outer cover 210, and the other end acts on the conductive member 22B in the direction of the second end face of the conductive member 22B, making the conductive member 22B in close contact with the cooling member 121. The conductive member 22B may be made of metal or ceramic provided around the light exit port of the outer cover 210, or may be a material capable of conducting cold air flow such as sapphire provided in the first light exit port 11. Here, sapphire can transmit light and has a better conductive effect on cold air flow. In this embodiment, an example in which sapphire provided in the first light exit port 11 is selected for both the cooling member 121 and the conductive member 22B will be described. During depilation, the cold air flow generated by the semiconductor cooling sheet 31 of the beauty device main body 1 passes through the cooling member 121 and the conductive member 22B in sequence and acts on the skin to cool the skin surface. Since the elastic member 22C acts on the conductive member 22B in the direction of the second end face of the conductive member 22B, the conductive member 22B is always subjected to a force directed towards the connection outer surface of the outer cover, so that it is in close contact with the cooling member 121, that is, the two sapphires are in close contact, facilitating the conduction of cold air flow to the skin, lowering the skin temperature, and improving the cooling effect on the skin by the beauty device and the user's use experience.
[0142] Referring to FIGS. 24 to 26, the elastic member 22C of this embodiment is used to apply an elastic force to the conductive member 22B and keep the conductive member 22B in constant close contact with the cooling member 121. Also, when there is an unexpected collision, the buffer effect of the elastic member 22C avoids the rigid collision between the conductive member 22B and the cooling member 121, protecting the two light guiding elements. The elastic member 22C may be a spring, rubber, elastic polymer, etc. For example, the elastic member 22C is an annular rubber structure. The following describes the installation method of the elastic member 22C.
[0143] As shown in FIGS. 24 and 29, in some embodiments, the attachment head 2B of the beauty device further includes an attachment frame 24 for attaching the conductive member 22B. The attachment frame 24 is provided surrounding the conductive member 22B. On the outside of the attachment frame 24, a flange portion 241 is formed. The elastic member 22C is provided on the side of the flange portion 241 away from the cooling assembly 30. One end of the elastic member 22C abuts against the flange portion 241, and the other end acts on the outer cover 210. The conductive member 22B of this embodiment is provided in a rectangular block shape. The inner frame of the attachment frame 24 encloses the conductive member 22B. The flange portion 241 on the outside of the attachment frame 24 engages with the outer cover 210, whereby the conductive member 22B is attached inside the outer cover 210. The elastic member 22C is provided on the side of the flange portion 241 away from the second end face of the conductive member 22B and is pressed between the flange portion 241 and the outer cover 210. When the attachment head 2B of the beauty device is fitted to the beauty device body 1, the conductive member 22B is in close contact with the cooling member 121, and the elastic member 22C deforms to apply an elastic force to the conductive member 22B in the direction of the second end face. Under the action of the elastic force, the conductive member 22B continuously presses the cooling member 121, making the conductive member 22B and the cooling member 121 more closely attached.
[0144] As shown in FIG. 25, in another embodiment, at least a part of the elastic member 22C is provided on the first end surface of the conductive member 22B. At least one end of the elastic member 22C abuts against the conductive member 22B, and at least the other end acts on the outer cover 210. At least one end of the elastic member 22C in this embodiment is pressed between the first end surface of the conductive member 22B and the outer cover 210. As can be understood, in this embodiment, the elastic member 22C may be entirely provided on the first end surface of the conductive member 22B, or only a part of the elastic member 22C may be provided on the first end surface of the conductive member 22B. Thereby, the elastic member 22C between the first end surface of the conductive member 22B and the outer cover 210 can apply a force acting towards the second end surface of the conductive member 22B to the conductive member 22B due to deformation. When the accessory head 2B of the beauty device is connected to the beauty device body 1, the conductive member 22B continuously presses the cooling member 121 due to the acting force of the elastic member 22C, and makes the conductive member 22B and the cooling member 121 fit more closely.
[0145] As shown in FIG. 26, in a further embodiment, a stepped portion capable of accommodating the elastic member 22C protrudes from the outer peripheral surface of the conductive member 22B. One end of the elastic member 22C facing the cooling member 121 abuts against the stepped portion, and the other end acts on the outer cover 210. The elastic member 22C in this embodiment abuts between the stepped portion and the outer cover 210. When the accessory head 2B of the beauty device is connected to the beauty device body 1, the conductive member 22B is in close contact with the cooling member 121, and the elastic member 22C deforms and applies an elastic force to the stepped portion in the direction of the cooling member 121. The conductive member 22B continuously presses the cooling member 121 under the action of the elastic force, and makes the conductive member 22B and the cooling member 121 fit more closely.
[0146] This application further includes a beauty device, which includes a beauty device main body 1 and the beauty device accessory head 2B described in the above embodiment. The beauty device accessory head 2B is fitted to the beauty device main body 1. The cold feeling assembly 30 is provided inside the first light emitting port 11 or on the outer periphery of the first light emitting port 11. A second light emitting port 211 is formed in the outer cover 210. The conduction member 22B is provided inside the second light emitting port 211 or on the outer periphery of the second light emitting port 211. The second light emitting port 211 is different in size from the first light emitting port 11.
[0147] As can be understood, when the cold feeling assembly 30 of the beauty device is provided inside the first light emitting port 11, the conduction member 22B of the beauty device accessory head 2B is provided inside the second light emitting port 211. However, when the cold feeling assembly 30 of the beauty device is provided on the outer periphery of the first light emitting port 11, the conduction member 22B of the beauty device accessory head 2B is also correspondingly provided on the outer periphery of the second light emitting port 211. In this way, when the beauty device accessory head 2B is fitted to the beauty device main body 1, the cold feeling assembly 30 and the conduction member 22B are in close contact with each other, and the conduction of the cold feeling can be realized.
[0148] In the attachment head 2B of the beauty device of this embodiment, in order to meet the hair removal needs of different body parts of the user, a second light emission port 211 with a size different from that of the first light emission port 11 of the beauty device main body 1 is provided. Specifically, the second light emission port 211 of the attachment head 2B of the beauty device faces the first light emission port 11, and the light emitted from the beauty device main body 1 acts on the human skin through the conduction member 22B in the second light emission port 211 to perform hair removal on the skin. Since the second light emission port 211 has a different size from the first light emission port 11, it can be used for hair removal on different parts of the body. For example, a hair remover with a larger light emission port can cover a wider range of skin and can increase the hair removal speed, and is suitable for the legs, back, etc. Since a wide range of light emission distribution can disperse light energy more uniformly, such a design can also reduce the irritation and discomfort to the skin. A hair remover with a smaller light emission port is suitable for areas of the skin that are small in range and difficult to reach, such as under the armpits and various parts of the face. Such a design can assist the user in more accurately aiming at the hair area to be processed, thereby reducing unnecessary exposure to the surrounding skin and avoiding unnecessary irritation to the surrounding skin. Therefore, since the first light emission port 11 and the second light emission port 211 of the hair remover according to this embodiment have different sizes, they can meet the hair removal needs of different parts of the skin and provide a more comfortable and effective hair removal experience. Optionally, the second light emission port 211 of this embodiment is smaller than the first light emission port 11.
[0149] At the same time, the attachment head 2B of the beauty device of this embodiment is detachably fitted to the beauty device main body 1, so that the user can easily replace the attachment head 2B for skin care. Specifically, the outer cover 210 of the attachment head 2B of the beauty device extends in both side directions of the second light emission port 211 to form two connection arms 212, and the two connection arms 212 are clamped on both sides of the beauty device main body 1. Exemplarily, the connection form between the connection arm 212 and the beauty device main body 1 may be engagement, insertion, magnetic attraction connection, etc., and the structure is compact and easy to carry.
[0150] In some embodiments, the two connecting arms 212 are elastic connecting arms 212. The volume of the clamping space formed between the two elastic connecting arms 212 is smaller than the connecting end of the beauty device body 1. Since the connecting arms 212 are elastic, when the connecting end of the beauty device body 1 is inserted into the clamping space, the clamping space becomes larger, and the elastic force of the two connecting arms 212 acts on both sides of the beauty device body 1, further clamping the beauty device body 1. Optionally, the two connecting arms 212 are clamped on both sides in the width direction of the beauty device body 1.
[0151] In some embodiments, continuing to refer to FIGS. 27 and 28, an engaging structure 2122 is provided between the connecting arm 212 and the beauty device body 1, and the connecting arm 212 is detachably attached to the beauty device body 1 by the engaging structure 2122.
[0152] Furthermore, the engaging structure 2122 includes a boss provided inside the connecting arm 212 and a groove provided outside the beauty device body 1, or the engaging structure 2122 includes a groove provided inside the connecting arm 212 and a boss provided outside the beauty device body 1.
[0153] In this embodiment, the connection form between the beauty device accessory head 2B and the beauty device body 1 is engagement, and the engaging structure 2122 is provided between the connecting arm 212 and the beauty device body 1. Specifically, a boss is provided inside at least one connecting arm 212, and a groove is provided at the corresponding position outside the beauty device body 1, or a groove is provided inside at least one connecting arm 212, and a boss is provided at the corresponding position outside the beauty device body 1. Here, when the groove and the boss are fitted and the beauty device accessory head 2B is fitted to the beauty device body 1, the boss is fitted into the groove to realize the engagement between the connecting arm 212 and the beauty device body 1.
[0154] In some embodiments, one end of the side wall of the beauty device main body 1 close to the accessory head 2B of the beauty device presents a first arc surface, and on one side where the two connecting arms 212 face each other, a position limiting groove 2121 for inserting the side wall of the beauty device main body 1 having the first arc surface is formed, and at least one inner surface of the position limiting groove 2121 is a second arc surface adapted to the first arc surface.
[0155] The accessory head 2B of the beauty device in this embodiment is connected to the beauty device main body 1 in an insertion manner. Specifically, one end of the side wall of the beauty device main body 1 close to the accessory head 2B of the beauty device presents an arc surface, and at least one inner surface of the position limiting groove 2121 also presents an arc surface, so that it fits the side wall of the beauty device main body 1 having the arc surface. When one end of the side wall of the beauty device main body 1 having the inner surface of the arc surface is inserted into the position limiting groove 2121, the position limiting groove 2121 plays a guiding role and facilitates the insertion of the beauty device main body 1. Optionally, a connection bottom plate 213 is further formed on the outer cover 210. The connection bottom plate 213 is connected between the two connecting arms 212. When the beauty device main body 1 is inserted into the position limiting groove 2121, the connection bottom plate 213 can receive the beauty device main body 1 and improve the reliability of the insertion.
[0156] In some embodiments, a first magnetic attraction member is provided on the accessory head 2B of the beauty device, and a second magnetic attraction member is provided at the corresponding position of the beauty device main body 1. The accessory head 2B of the beauty device is detachably attached to the beauty device main body 1 by the mutual attraction of the first magnetic attraction member and the second magnetic attraction member. Alternatively, the connecting arm 212 is made of a magnetic material, and a second magnetic attraction member is provided outside the beauty device main body 1. The connecting arm 212 is detachably attached to the beauty device main body 1 by magnetic attraction.
[0157] The accessory head 2B of the beauty device in this embodiment is connected to the beauty device main body 1 by a magnetic attraction connection method. Specifically, the first magnetic attraction member is provided on the accessory head 2B of the beauty device, the second magnetic attraction member is provided on the beauty device main body 1, and when the accessory head 2B of the beauty device is fitted to the beauty device main body 1, the first magnetic attraction member and the second magnetic attraction member are attracted to each other, realizing the magnetic attraction connection between the accessory head 2B of the beauty device and the beauty device main body 1. Alternatively, the connection arm 212 of the accessory head 2B of the beauty device is made of a magnetic material, and the second magnetic attraction member directly attracts the connection arm 212. Here, the magnetic attraction material may be iron, an iron alloy, etc., and the first magnetic attraction member and the second magnetic attraction member may be magnets.
[0158] Continuing to refer to FIGS. 27 and 28, in some embodiments, the accessory head 2B of the beauty device is provided with a first conductive contact 25, and the beauty device main body 1 is provided with a second conductive contact 13B. When the accessory head 2B of the beauty device is fitted to the beauty device main body 1, the first conductive contact 25 comes into contact with the second conductive contact 13B and is electrically connected.
[0159] In this embodiment, when the accessory head 2B of the beauty device is attached to the beauty device main body 1, the accessory head 2B is electrically connected to the beauty device main body 1, and the accessory head 2B obtains electrical energy from the beauty device main body 1 and performs skin care operations. Specifically, the first conductive contact 25 is provided on the accessory head 2B of the beauty device, the second conductive contact 13B is provided on the beauty device main body 1, and when the accessory head 2B of the beauty device is fitted to the beauty device main body 1, the first conductive contact 25 comes into contact with the second conductive contact 13B and is electrically connected, thereby realizing the electrical connection between the accessory head 2B of the beauty device and the beauty device main body 1.
[0160] Optionally, the first conductive contact 25 includes a plurality of elastic electrodes arranged at intervals, and the second conductive contact 13B includes a plurality of elastic electrodes provided at intervals. When the attachment head 2B of the beauty device is fitted to the beauty device main body 1, the elastic electrodes of the first conductive contact 25 and the elastic electrodes of the second conductive contact 13B come into contact with each other in a one-to-one correspondence and are pressed against each other, whereby the attachment head 2B of the beauty device is electrically connected to the beauty device main body 1.
[0161] Optionally, the first conductive contact 25 is provided on the connection bottom plate 213, and the second conductive contact 13B is provided on a surface facing the connection bottom plate 213 of the beauty device main body 1.
[0162] Optionally, the connection bottom plate 213 is connected between the two connection arms 212 of the attachment head 2B of the beauty device and forms an accommodation space with the two connection arms 212. When the attachment head 2B of the beauty device is fitted to the beauty device main body 1, the beauty device main body 1 partially protrudes into the accommodation space, whereby the first conductive contact 25 on the connection bottom plate 213 comes into contact with the second conductive contact 13B on the bottom surface of the beauty device main body 1 and is electrically connected.
[0163] Continuing to refer to FIG. 29, in some embodiments, the attachment head 2B of the beauty device further includes a detection member 26 provided at the second light emitting port 211. The detection member 26 is electrically connected to the first conductive contact 25 and is provided surrounding the conduction member 22B and is used to detect the human skin.
[0164] The detection member 26 of this embodiment is used to detect the human skin. Specifically, the detection member 26 is provided surrounding the conductive member 22B and is electrically connected to the second conductive contact 13B. When the beauty device attachment head 2B is attached to the beauty device main body 1, the conductive member 22B faces the cooling member 121, the detection member 26 is electrically connected to the beauty device main body 1, and when the detection member 26 approaches or contacts the skin, the detection member 26 sends an operation signal to the beauty device main body 1, and the beauty device main body 1 emits light, and the light is conducted to the human skin through the conductive member 22B to perform hair removal on the skin.
[0165] Continuing to refer to FIG. 24, in some embodiments, the elastic member 22C abuts between the detection member 26 and the flange portion 241 of the mounting frame 24, and the detection member 26 is fixedly attached to the second light emission port 211. When the beauty device attachment head 2B is fitted to the beauty device main body 1, the conductive member 22B is in close contact with the cooling member 121, the elastic member 22C deforms and applies an elastic force to the conductive member 22B in the direction of the cooling member 121, and the conductive member 22B continuously compresses the cooling member 121 under the action of the elastic force to make the conductive member 22B and the cooling member 121 more closely attached.
[0166] A further embodiment of the present application proposes a beauty device. Referring to FIG. 1, the beauty device includes a housing 10, a beauty assembly and a heat dissipation assembly, and both the beauty assembly and the heat dissipation assembly are provided in the housing 10. Here, the beauty assembly is used to care for the surface of the human skin and generates heat inside the housing 10 during operation, and the heat dissipation assembly is used to discharge the heat inside the housing 10 to the outside to prevent the housing 10 from generating heat due to heat concentration.
[0167] As shown in FIGS. 2 and 3, the housing 10 is provided with an air inlet hole 13 and a plurality of air discharge holes 12. The heat dissipation assembly generally includes an air flow generating device and a heat sink 42. The heat dissipation assembly is provided within the housing 10 and includes the air flow generating device and the heat sink 42. Also, the air flow generating device includes an air inlet and an air outlet. The air inlet of the air flow generating device communicates with the air inlet hole 13. The heat sink 42 has a first air discharge port K1 that communicates with the air discharge hole 12 and an air flow inlet K2 that communicates with the air outlet of the air flow generating device. Further, the air outlet of the air flow generating device communicates with the heat sink 42. A part of the cooling air generated by the air flow generating device passes through the heat sink 42, then carries out the heat on the heat sink 42, and is discharged from the air discharge hole 12 formed in the housing 10. As can be understood, when the air flow generating device is operating, the external cooling air flows into the housing 10 from the outside through the air inlet hole 13 formed in the housing 10, and then flows into the air flow generating device.
[0168] Furthermore, as shown in conjunction with FIGS. 4 to 8, in this embodiment, a first gas flow path 16 is provided in the housing 10. The first gas flow path 16 includes a gas inlet and a gas outlet. The beauty assembly is provided in the housing 10 and is located in the first gas flow path 16. The air outlet of the air flow generating device further communicates with the gas inlet of the first gas flow path 16. The gas outlet of the first gas flow path 16 communicates with the air discharge hole 12. A part of the cooling air generated by the air flow generating device enters the first gas flow path 16 from the gas inlet of the first gas flow path 16, and then flows from the gas outlet to the air discharge hole 12 and is discharged. Another part of the cooling air generated by the air flow generating device enters the heat sink 42 from the air inlet K2 of the heat sink 42, and then flows from the first air outlet K1 to the air discharge hole 12 and is discharged. Here, the housing 10 has an upper surface, a bottom surface, and side surfaces. Each air discharge hole 12 is located on the upper surface of the housing 10 or the bottom surface of the housing 10 all at once. Since the air discharge holes 12 are not provided on the side surface of the housing 10 nor on two surfaces of the housing 10, when the beauty device is in use, all of the air discharge holes 12 may be turned away from the user at the same time. As can be understood, in some other embodiments, the first gas flow path 16 is not provided in the beauty device. In this case, all of the cooling air generated by the air flow generating device flows out from the first air outlet K1 to the air discharge hole 12 after passing through the heat sink 42.
[0169] In the beauty device of the present application, a first gas flow path 16 and a heat sink are provided. A part of the cooling air generated by the air flow generating device flows out from the gas outlet of the first gas flow path 16 to the air discharge hole of the housing after passing through the first gas flow path 16. Another part of the cooling air generated by the air flow generating device flows out from the first air outlet of the heat sink to the air discharge hole of the housing after passing through the heat sink. Thereby, the heat dissipation effect inside the beauty device is enhanced. Also, since all of the air discharge holes on the housing are located on the same surface of its upper surface or bottom surface, when the user uses the beauty device, no matter which hand holds the beauty device, none of the air discharge holes of the beauty device will face the user. Therefore, the risk of the user being burned can be reduced.
[0170] Exemplarily, each air discharge hole 12 is located on the bottom surface of the housing 10. When the user performs skin care with the beauty device, the bottom surface of the housing 10 may face outward, and by turning the back of the air discharge hole 12 towards the user, heat is prevented from being discharged to the human body. For example, when the user holds the beauty device with the left hand, the user holds the upper surface of the housing 10 with the thumb and holds the bottom surface of the housing 10 with the remaining four fingers, and brings the cooling assembly 30 into contact with the human skin. When the user holds the beauty device with the right hand, the user holds the upper surface of the housing 10 with the thumb and holds the bottom surface of the housing 10 with the remaining four fingers, and brings the cooling assembly 30 into contact with the human skin. In this way, no matter which hand the user holds the beauty device with, the air discharge holes of the beauty device will not all face the user.
[0171] When they do not conflict with each other, those skilled in the art can combine the different embodiments described in this specification and their features.
[0172] The above is only a part of the embodiments of the present application, and neither the text nor the accompanying drawings can limit the protection scope of the present application. Under the overall concept of the present application, equivalent structural changes made using the content of the specification and the accompanying drawings of the present application, or direct / indirect applications to other related technical fields are all included in the protection scope of the present application.
