[0056] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0060] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0061] The flash speed of existing hair removal devices is getting faster and faster, which makes the lamp head of the hair removal device prone to overheating. The sapphire freezing point hair removal device currently on the market uses semiconductor cooling chips and light-transmitting crystals to output light to avoid the temperature of the part that is in direct contact with the user's skin from being too high, but this hair removal device has a complex structure, easily damaged parts, and high cost.

[0062] Based on this, the first embodiment of the utility model provides a hair removal device 1 to solve the problem that the lamp head of the above-mentioned hair removal device is prone to overheating, and compared with the existing sapphire freezing point hair removal device, the structure is simpler and the cost is lower.

[0063] See also Figure 1-Figure 3 The first embodiment of the utility model provides a hair removal device 1, comprising a main body 10 with a light outlet 17 and a light outlet head 20 disposed at the light outlet 17;

[0064] The main body 10 is provided with a light source structure 11 and a fan 12 arranged on a side of the light source structure 11 away from the light output head 20;

[0065] The light head 20 includes a bracket 21 and a light-transmitting member 22 arranged in the bracket 21. The light-emitting surface of the light-transmitting member 22 faces away from the light source structure 11 and forms a groove space 23 with the bracket 21. At least one side surface of the bracket 21 is provided with an air hole 211 connected to the groove space 23; at least part of the airflow generated by the fan 12 enters the groove space 23 through the air hole 211.

[0066] Specifically, the light emitting surface of the light source structure 11 corresponds to the light outlet 17 on the main body 10, and a light head 20 can be set corresponding to the light outlet 17. The position and size of the light-transmitting component 22 in the light head 20 match the position and size of the light source structure 11, so that the light of the light source structure 11 passes through the light outlet 17 and the light-transmitting component 22 on the light head 20 in turn.

[0067] More specifically, the surface of at least one side of the bracket 21 with the air hole 211 is at least one enclosed surface of the bracket 21 that encloses the light-transmitting member 22. The light-transmitting member 22 in the light-emitting head 20 and the bracket 21 are both away from the end of the light source structure 11, that is, there is a distance difference between the boundary of the light-transmitting member 22 at the end that is not connected to the light outlet 17 and the boundary of the bracket 21, so that the light-emitting surface of the light-transmitting member 22 in the light-emitting head 20 away from the light source structure 11 and the end of the bracket 21 away from the light source structure 11 form a groove space 23. At the same time, the existence of this distance difference can enable the air hole 211 corresponding to the distance difference area formed on the bracket 21 to be connected to the groove space 23, so as to penetrate the interior of the main body 10 of the hair removal device 1 through the air hole 211.

[0068] It can be understood that the air holes 211 on the bracket 21 and the light-emitting surface of the light-transmitting member 22 facing away from the light source structure 11 are connected with the groove space 23 formed by the bracket 21, so that the interior of the main body 10 can be connected with the groove space 23 through the air holes 211, and thus connected with the outside world through the groove space 23, so as to directly blow air to dissipate heat to the skin area corresponding to the groove space. In addition, it is also possible to achieve that part of the wind flow generated by the fan 12 is contracted to the light-emitting surface of the light source structure 11 to discharge air, thereby reducing the temperature of the part of the light-emitting head 20 that is in direct contact with the skin, thereby preventing the light-emitting head 20 from overheating when the hair removal device 1 is in use. In addition, by contracting the part of the wind flow generated by the fan 12 to the light-emitting surface of the light source structure 11, it is achieved that the heat dissipation inside the hair removal device 1 and the temperature of the part in direct contact with the skin can be achieved without setting a semiconductor refrigeration plate to cooperate with the light-transmitting crystal to emit light, so that the hair removal device 1 of the utility model is simpler in structure and lower in cost than the existing sapphire freezing point hair removal device 1.

[0069] Optionally, air holes 211 connected to the groove space 23 can be opened on all the enclosed surfaces of the enclosed light-transmitting member 22 of the bracket 21, so as to increase the air flow area for part of the wind generated by the fan 12 to enter the outside by increasing the number of air holes 211, and enable all boundary sides of the light-transmitting member 22 facing away from the light outlet 17 to discharge air, that is, part of the wind flow generated by the fan 12 is uniformly contracted toward the surrounding side of the light outlet surface of the light source structure 11 to discharge air, so that the part of the light outlet head 20 that is in direct contact with the skin can be cooled more evenly.

[0070] Optionally, the light head 20 and the main body 10 can be fixedly connected by bolt connection, adhesive connection, integral molding, etc., or can be detachably connected by plug-in connection, snap connection, magnetic connection, etc.

[0071] Specifically, in the embodiment of the utility model, the light head 20 is detachably connected to the main body 10. More specifically, the light head 20 is plugged into the light outlet 17 of the main body 10 through the end of the bracket 21 away from the light emitting surface of the light-transmitting member 22, and the light-transmitting member 22 corresponds to the light source structure 11. Thus, the light head 20 is detachably connected to the main body 10 by plugging, which makes it easier to replace the light head 20 and is more conducive to the inspection and maintenance of the hair removal device 1.

[0072] See also Figure 3 Furthermore, a first circuit board 15 and a second circuit board 16 arranged at a preset spacing are also provided inside the shell 14. The first circuit board 15 is connected to the sensing element, and the second circuit board 16 is connected to the fan 12. The first circuit board 15 and the second circuit board 16 are parallel and inclined relative to the shell 14.

[0073] It can be understood that the tilted arrangement of the first circuit board 15 and the second circuit board 16 inside the housing 14 can increase the area where the first circuit board 15 and the second circuit board 16 can be arranged, which is more conducive to the arrangement of the circuit board. The first circuit board 15 and the second circuit board 16 are spaced and arranged in parallel, so that there is a space with a preset spacing between the first circuit board 15 and the second circuit board 16 to separate the first circuit board 15 and the second circuit board 16. Thereby, the space for the first circuit board 15 and the second circuit board 16 to dissipate heat is increased, so that the heat emitted by the first circuit board 15 and the second circuit board 16 can be sucked in and discharged from the inside of the hair removal device 1 through the fan 12, which is more conducive to the heat dissipation of the first circuit board 15 and the second circuit board 16, and avoids the excessive temperature inside the hair removal device 1 affecting the circuit board.

[0074] See also Figure 3 Furthermore, the light source structure 11 includes a filter 111, a light source 112 and a reflector 113. The filter 111 is arranged in the light emitting direction of the light source 112, and the reflector 113 is arranged in the backlight direction opposite to the light emitting direction of the light source 112.

[0075] It can be understood that the light source element 112 in the light source structure 11 is used to emit light, and the reflector 113 arranged in the backlight direction opposite to the light emitting direction of the light source element 112 reflects all the light emitted by the light source element 112 to the side away from the light emitting head 20, and reflects it to the filter 111, so that the filter 111 filters the light directly emitted by the light source and the light reflected by the reflector 113. The filtered light passes through the light-transmitting element 22 of the light emitting head 20 and is directly irradiated on the skin, thereby realizing the use of the light source structure 11 to emit light for skin hair removal and / or care.

[0076] See also Figure 3 Furthermore, an air supply component 13 is also provided inside the main body 10, and a main air supply channel 1311 is provided inside the air supply component 13. At least part of the airflow generated by the fan 12 passes through the main air supply channel 1311 and the air hole 211 in sequence and enters the groove space 23.

[0077] It can be understood that a main air supply channel 1311 can be formed inside the air supply component 13, one end of the main air supply channel 1311 corresponds to the air outlet of the fan 12, and the other end is connected to the groove space 23. Therefore, the wind generated by the fan 12 is sent to the air hole 211 through the main air supply channel 1311 and enters the groove space 23, and then enters the outside world, realizing the control of the direction of the wind flow through the main air supply channel 1311.

[0078] See also Figure 3 Furthermore, the main body 10 includes a shell 14, and the light source structure 11, the fan 12 and the air supply assembly 13 are all located inside the shell 14. An air inlet hole 1421 is opened on the shell 14, and the external wind flow enters the fan 12 through the air inlet hole 1421, and at least part of the wind flow entering the fan 12 passes through the main air supply channel 1311 and the air hole 211 in turn to enter the groove space 23.

[0079] It can be understood that the main body 10 includes a shell 14, and a receiving groove can be formed inside the shell 14, and the receiving groove is used to accommodate the light source structure 11, the fan 12 and the air supply assembly 13. A plurality of air inlet holes 1421 are provided on the shell 14 corresponding to the air inlet of the fan 12, and the plurality of air inlet holes 1421 are combined to form an air inlet area, and the size and shape of the air inlet area match the shape and shape of the fan 12, so that the wind flow outside the shell can enter the fan 12 through the air inlet holes 1421, and at least part of the wind flow entering the fan 12 can enter the groove space 23 through the main air supply channel 1311 and the air hole 211 in turn, so that the outside wind flow can enter the fan 12 more easily.

[0080] See also Figure 4-Figure 6Furthermore, the air supply component 13 includes a first air supply member 131 and a second air supply member 132. A main air supply channel 1311 that passes through the air outlet of the fan 12 is formed inside the first air supply member 131. The second air supply member 132 is arranged on a side of the first air supply member 131 close to the light source structure 11; an auxiliary air supply channel 1321 corresponding to the air hole 211 on the bracket 21 is formed between the first air supply member 131 and the second air supply member 132. The main air supply channel 1311 is connected to the groove space 23 through the auxiliary air supply channel 1321 and the air hole 211 in sequence.

[0081] It can be understood that the second air supply member 132 is disposed between the first air supply member 131 and the light source structure 11, and a secondary air supply channel 1321 corresponding to the air hole 211 on the bracket 21 is formed between the first air supply member 131 and the second air supply member 132, the secondary air supply channel 1321 is connected to the main air supply channel 1311, and the secondary air supply channel 1321 passes through the side of the light source structure 11 corresponding to the air hole 211. Thus, the air flow blown in by the fan 12 enters the secondary air supply channel 1321 located on at least one side of the light source structure 11 from the main air supply channel 1311, and part of the air flow entering the secondary air supply channel 1321 is blown along the first air supply direction f1 (such as Figure 4 f1) shown in the figure, so as to enter the groove space 23 through the air hole 211 from the auxiliary air supply channel 1321, thereby directly blowing air to the skin area corresponding to the groove space 23 to dissipate heat. In addition, part of the wind flow generated by the fan 12 is contracted toward the light emitting surface of the light source structure 11 to discharge air, which can also reduce the temperature of the part of the light emitting head 20 that is in direct contact with the skin.

[0082] It should be noted that the auxiliary air supply channel 1321 formed between the second air supply member 132 and the first air supply member can enclose the circumference of the light source structure 11, and the circumference of the bracket 21 enclosing the light-transmitting member 22 is provided with air holes 211, thereby realizing the contraction of the air outlet on the four sides of the enclosed light-transmitting member 22 on the light output head 20, making the heat dissipation of the light output head 20 more uniform and further improving the heat dissipation effect.

[0083] See also Figure 4-Figure 6 Furthermore, a third air supply member 133 is provided on at least one side of the second air supply member 132, and a distribution air supply channel 1331 is formed inside the third air supply member 133. A heat dissipation space 1322 connecting the main air supply channel 1311 and the distribution air supply channel 1331 is formed between the second air supply member 132 and the light source structure 11; an air outlet hole 1431 is opened on the shell 14, and the heat dissipation space 1322 is connected to the outside through the distribution air supply channel 1331 and the air outlet hole 1431 in turn.

[0084] It can be understood that the side of the second air supply member 132 away from the main air supply channel 1311 and the side of the light source structure 11 away from the light outlet 17 form a heat dissipation space 1322, and the heat dissipation space 1322 is connected to the main air supply channel 1311. A third air supply member 133 can be provided on at least one side of the second air supply member 132. A distribution air supply channel 1331 can be formed inside the third air supply component 13, and the distribution air supply channel 1331 is connected to the heat dissipation space 1322, so that the main air supply channel 1311 is connected to the distribution air supply channel 1331 through the heat dissipation space 1322. In this way, the wind flow generated by the fan 12 entering the main air supply channel 1311 can be diverted, so that a part of the wind flow entering the main ventilation passes through the auxiliary ventilation channel and the air hole 211 in turn and enters the groove space 23, so that a part of the wind flow generated by the fan 12 is contracted and discharged along the first air supply direction f1 toward the light outlet surface of the light source structure 11; the other part of the wind flow is discharged along the second air supply direction f2 (such as Figure 5 The light f2) shown is blown into the heat dissipation space 1322 formed by the light source structure 11 and the second air supply member 132, and sequentially passes through the air distribution channel 1331 and the air outlet 1431 to the outside, thereby directly dissipating the heat of the light source structure 11, realizing the air distribution heat dissipation on both sides of the hair removal device 1, so as to improve the heat dissipation effect of the light source structure 11. In addition, the dual-path air distribution heat dissipation of the auxiliary ventilation channel and the auxiliary ventilation channel of the hair removal device 1 is realized.

[0085] See also Figure 4-Figure 6 Furthermore, the second air supply member 132 is respectively provided with a first opening 1323 and a second opening 1324 that penetrate the heat dissipation space 1322 corresponding to the main air supply channel 1311 and the distribution air supply channel 1331. At least part of the airflow generated by the fan 12 enters the heat dissipation space 1322 through the main air supply channel 1311 and the first opening 1323 in sequence, and enters the outside through the second opening 1324, the distribution air supply channel 1331 and the air outlet 1431 in sequence.

[0086] It can be understood that the first opening 1323 and the second opening 1324 can be respectively provided at the channel opening of the corresponding distribution air channel 1331 on the second air supply member 132 and the channel opening of the main air supply channel 1311 away from the fan 12, so that the distribution air channel 1331 and the main air supply channel 1311 are connected through the first opening 1323 and the second opening 1324, so that the main air supply channel 1311 is connected with the distribution air channel 1331. In this way, the wind flow generated by the fan 12 and entering the main air supply channel 1311 is diverted, so that a part of the wind flow entering the main ventilation passes through the first opening 1323 and enters the heat dissipation space 1322 formed by the light source structure 11 and the second air supply member 132, and passes through the distribution air channel 1331 and the air outlet 1431 to the outside in turn, so as to directly dissipate the heat of the light source structure 11, so as to improve the heat dissipation effect of the light source structure 11.

[0087] See also Figure 4-Figure 6 Furthermore, a partition plate 1312 is provided inside the first air supply member 131 , and two ends of the partition plate 1312 correspond to the first opening 1323 and the air outlet of the fan 12 respectively.

[0088] It can be understood that a partition 1312 is provided in the first air supply member 131, and the partition 1312 is provided on the side wall of the first air supply component 13, and at the same time, the two ends of the partition 1312 correspond to the first opening 1323 and the air outlet of the fan 12, respectively, so that the main air supply channel 1311 is separated by the partition 1312 to form two layers of air supply channels. As a result, the wind flow blown into the main air supply channel 1311 by the fan 12 is directly diverted by the partition 1312 and enters the corresponding air supply channel of each layer. In this way, the wind flow in the main air supply channel 1311 is diverted to control the direction of the wind flow, so that the wind flow is more likely to enter the distribution air channel 1331 and the auxiliary air supply channel 1321.

[0089] See also Figure 7 Furthermore, the shell 14 includes a first shell 141, a second shell 142 and a frame 143, the first shell 141 is connected to the second shell 142 through the frame 143; the air inlet 1421 is located on the second shell 142, and the air outlet 1431 is located at one end of the frame 143 close to the light output head 20.

[0090] It can be understood that the first shell 141 and the second shell 142 are respectively snapped on opposite sides of the shell frame 143 to form the shell 14. The air inlet 1421 can be located at the position of the second shell 142 corresponding to the air inlet of the fan 12, so that the fan 12 can directly draw air from the outside through the air inlet 1421. The air outlet 1431 can be located at one end of the shell frame 143 close to the light outlet head 20, and is located in the connection position area of ​​the shell frame 143 connecting the first shell 141 and the second shell 142. Thereby, the position of the air outlet 1431 can correspond to the air distribution channel 1331, which is more conducive to air outlet. In addition, arranging the air outlet 1431 on the shell frame 143 can hide the air outlet 1431 as much as possible, avoiding directly arranging the air outlet 1431 on the second shell 142, which affects the overall aesthetics of the hair removal device 1.

[0091] See also Figure 7-Figure 9 Furthermore, at least one sensor is provided at one end of the main body 10 where the light outlet 17 is provided. When the light head 20 is connected to the main body 10, the main body 10 determines whether the light head 20 is plugged in place according to the sensor.

[0092] It can be understood that a sensing element can be provided at one end of the main body 10 where the light outlet 17 is provided. When the light outlet 20 is plugged into the light outlet 17 of the main body 10, the sensing element can sense whether the light outlet 20 is plugged into the light source structure 11 and determine whether the light outlet 20 is correctly plugged in through sensing, so as to control the hair removal device 1 to start normally only when it is correctly plugged in.

[0093] See also Figure 7-Figure 9 Furthermore, the shell 14 also includes an end cover 144, which is connected to one end of the shell frame 143 facing the light emitting direction; the sensing component is a Hall sensor 171, which is arranged between the end cover 144 and the light source structure 11, and a magnetic component 24 is provided on the light emitting head 20 corresponding to the Hall sensor 171.

[0094] Specifically, the end cap 144 in the shell 14 can be sleeved on one end of the shell frame 143 facing the light emitting direction, that is, sleeved on one end of the shell frame 143 corresponding to the light emitting surface of the light source structure 11, so as to protect the light source structure 11 inside. The sensing element in the main body 10 can be arranged between the end cap 144 and the light source structure 11 to prevent the sensing element from being directly exposed to the plug-in position between the light emitting head 20 and the main body 10, thereby affecting the sensing of the sensing element. The type of the sensed element can be selectively set in the light emitting head 20 according to the type of the sensing element. For example, when the sensing element in the main body 10 is a Hall sensor 171, the sensed element arranged on the light emitting head 20 is a magnetic element 24; when the sensing element in the main body 10 is a photoelectric sensing device, the sensed element can be a reflective element 113, a light absorbing element or a light shielding element; when the sensing element in the main body 10 is a micro-motion sensing element, the sensed element can be a touch element. Therefore, through different types of sensing components and matching sensing components, the main body 10 can be matched with different types of light output heads 20, thereby achieving different functions.

[0095] It can be understood that in this embodiment, preferably, the sensing component is a Hall sensor 171, so a magnetic component 24 corresponding to the Hall sensor 171 can be provided on the light head 20. By sensing the magnetic component 24 through the Hall sensor 171, when the light head 20 is plugged into the main body 10, the main body 10 can detect whether the light head 20 is plugged in place according to the docking between the Hall sensor 171 and the magnetic component 24, thereby controlling the start of the power supply to avoid the situation where the light source structure 11 emits light without plugging in the light head 20 and burns people.

[0096] See also Figure 8-Figure 9Furthermore, the main body 10 also determines the type of the light-transmitting member 22 in the light-emitting head 20 according to the sensing member; the shell 14 also includes an end cover 144, and the end cover 144 is connected to one end of the shell frame 143 facing the light-emitting direction; the sensing member is a Hall sensor 171, and at least two Hall sensors 171 are arranged between the end cover 144 and the light source structure 11, and a magnetic member 24 is arranged at at least one location on the bracket 21 corresponding to the Hall sensor 171.

[0097] Specifically, the hair removal device 1 in this embodiment includes a plurality of light outlet heads 20, and the types and / or wavelengths of the light-transmitting members 22 in the plurality of light outlet heads 20 are different. When the main body 10 is plugged with different light outlet heads 20, it can identify and sense the range of the types and / or wavelengths of the light-transmitting members 22 in the light outlet heads 20. Thus, the light emitted by the light source structure 11 in the main body 10 can be matched with the light-transmitting member 22 in the corresponding light outlet head 20, thereby emitting light corresponding to the type and / or wavelength of the light-transmitting member 22 that can act on the skin to achieve different functions.

[0098] It can be understood that when the sensing element is a Hall sensor 171, the number of Hall sensors 171 disposed between the end cap 144 and the light source structure 11 and the positions of Hall sensors 171 with different numbers can be controlled, and the number and position of Hall sensors 171 disposed on the light output head 20 corresponding to the number and position can be controlled. Thus, the hair removal device 1 can achieve different functions through different numbers and different positions of Hall sensors 171 and the corresponding magnetic elements 24.

[0099] It can be understood that in this embodiment, preferably, at least two Hall sensors 171 can be set, and a magnetic member 24 can be set at at least one place in the light head 20, so that the hair removal device 1 can achieve different functions such as hair removal, beauty, and freckle removal by the number of magnetic members 24 set. For example, when two Hall sensors 171 can be set and located on both sides of the light source structure 11, the hair removal device 1 may include three types of light heads 20, and the type and / or wavelength of the light-transmitting member 22 in each light head 20 is different, and the number and / or position of the magnetic member 24 set on each light head 20 is different. Specifically, the Hall sensors 171 corresponding to different sides of each light head 20 can be respectively set with 0 or 1 magnetic member 24. Therefore, the three light heads 20 can be respectively set with 1, 1 and 2 magnetic members 24, and the positions of the magnetic members 24 in the two light heads 20 with the same number correspond to the single Hall sensors 171 on different sides of the light source structure 11. Thereby, the hair removal device 1 can realize three different functions, namely, hair removal, beauty and whitening, and freckle removal.

[0100] See also Figure 10-12, the embodiment of the utility model provides an example of functional matching, two Hall sensors 171 are arranged in the main body 10, namely Hall sensor 171a and Hall sensor 171b, and the light head 20 includes a first position C and a second position D. When the light head 20 is inserted into the light outlet 17 of the main body 10, the first position C and the second position D correspond to the Hall sensor 171a and the Hall sensor 171b respectively. Whether the first position C and the second position D are provided with a magnetic part 24, there are three cases: in the first case, the first position C is provided with a magnetic part 24, and the second position D is not provided with a magnetic part 24. The light head 20 with this setting is set to have a beauty and whitening effect. At this time, only the Hall sensor 171a can sense the magnetic field strength corresponding to the set threshold, and send a start signal and a light with a whitening effect intensity to the first circuit board 15 and / or the second circuit board 16 (such as Fig.10 In the second case, the second position D is provided with a magnetic member 24, and the first position C is not provided with a magnetic member 24. The light head 20 with this configuration is set to have an acne removal effect. At this time, only the Hall sensor 171b can sense the magnetic field strength corresponding to the set threshold value, and send a start signal and a light with an acne removal effect intensity to the first circuit board 15 and / or the second circuit board 16 (as shown). Fig.11 In the third case, the first position C and the second position D are both provided with a magnetic member 24, and the light head 20 provided with this configuration is set to have a hair removal function. At this time, the Hall sensor 171a and the Hall sensor 171b can both sense the magnetic field strength corresponding to the set threshold, and send a start signal and a light of the hair removal function intensity to the first circuit board 15 and / or the second circuit board 16 (as shown). Fig.12 shown).

[0101] See also Figure 7 and Fig. 9 Furthermore, a groove 25 is provided on any single side surface of the bracket 21 that faces the side of the main body 10 and encloses the light-transmitting member 22, and a protrusion 1441 is provided on the end cover 144 corresponding to the groove 25; when the light head 20 is inserted into the light outlet 17, the protrusion enters the groove 25.

[0102] It can be understood that a groove 25 can be provided on the surface of the bracket 21 on the side facing the main body 10. The surface includes four single-sided surfaces that enclose the four sides of the light-transmitting member 22, and the groove 25 can be provided on any single-sided surface of the four single-sided surfaces. A protrusion 1441 matching the groove 25 can be provided on the end cap 144 corresponding to the groove 25. When the light head 20 is inserted into the light outlet 17, the protrusion can enter the groove 25 to complete the plugging of the light head 20. And the groove 25 and the protrusion 1441 are set together on one side to prevent the light head 20 from being reversely inserted, thereby affecting the light output. It can also be understood that the setting positions of the groove 25 and the protrusion 1441 can also be interchanged, so as to achieve the effect of setting the groove 25 and the protrusion 1441 on one side between the light head 20 and the main body 10 to prevent reverse connection.

[0103] See also Fig. 9 Furthermore, the bracket 21 includes an inserting portion 212 and an exposed portion 213. When the light head 20 is inserted into the light outlet 17, the inserting portion 212 enters the light outlet 17, and the exposed portion 213 is exposed outside the light outlet 17; a buckle 26 is provided on the edge of the exposed portion 213, and the buckle 26 protrudes relative to the end cover 144.

[0104] It can be understood that the bracket 21 includes a plug-in portion 212 that can be plugged into the light outlet 17 of the main body 10 and an exposed portion 213 connected to the plug-in portion 212. When the plug-in portion 212 enters the light outlet 17, the exposed portion 213 is exposed outside the light outlet 17, and the side of the exposed portion 213 that is away from the light outlet 17 is the side that directly contacts the skin. A buckle 26 can be provided on the edge of the exposed portion 213. When the light head 20 is plugged into the light outlet 17 of the main body 10, the buckle 26 can protrude relative to the end cover 144, thereby making it easier to plug and unplug the light head 20.
