[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] This utility model embodiment provides a hair removal device, such as Figures 1 to 8 As shown, the hair removal device includes a housing 1, a lampshade 2, a lamp tube 3, a light power detection sensor 4, a circuit board 5, and a display screen 6. One end of the housing 1 has a light emission window 131. The lampshade 2, the light power detection sensor 4, and the circuit board 5 are installed inside the housing 1. The lamp tube 3 is installed in the lampshade 2. The lampshade 2 is set to correspond to the light emission window 131 so that the light source of the lamp tube 3 can be emitted from the light emission window 131.

[0021] The lampshade 2 has a detection port 21, and the light power detection sensor 4 is connected to the detection port 21; the display screen 6 is installed on the housing 1, and the lamp tube 3, the light power detection sensor 4 and the display screen 6 are electrically connected to the circuit board 5 respectively; the light power detection sensor 4 is used to detect the light power of the lamp tube 3, and the display screen 6 is used to display the power of the lamp tube 3.

[0022] The hair removal device of this invention is equipped with a light power detection sensor 4, which is directly set at the detection port 21 on the lamp cover 2. This arrangement allows the light power detection sensor 4 to be closer to the lamp tube 3, resulting in more accurate light power detection results. The light power detection results detected by the light power detection sensor 4 are displayed on the display screen 6, making the actual working power detection of the hair removal device more accurate and providing a better user experience.

[0023] Specifically, lamp 3 is an IPL lamp. IPL (Intense Pulsed Light) is a high-intensity pulsed light source emitted by a pulsed xenon lamp. It belongs to the arc discharge type of gas discharge lamp, which uses stored electrical or chemical energy to produce a high-intensity flash in a very short time. IPL has a wide spectral range, with wavelengths between 160 and 2000 nm and a central peak of 480 nm to 800 nm.

[0024] The circuit board 5 is equipped with necessary control chips and circuits. Circuit board 5 serves as the power control, distribution, and signal transmission control component for the hair removal device. It can be implemented using solutions known to those skilled in the art, and will not be elaborated further here. The actual operating power of the lamp 3 detected by the light power detection sensor 4 is displayed on the display screen 6 for the user to adjust the power for reference. The display screen 6 can be an LED display screen, etc., and the light power detection sensor 4 can be a light intensity sensor, an energy meter probe, etc. The display screen 6 and the light power detection sensor 4 can also be implemented using solutions known to those skilled in the art, and will not be elaborated further here.

[0025] Specifically, such as Figure 8 As shown, the detection port 21 is located on the back of the lampshade 2 away from the light-emitting window 131, and the light power detection sensor 4 is located on the back of the lampshade 2.

[0026] like Figures 1 to 3 As shown, the housing 1 may include an upper housing 11 and a lower housing 12. A display window 111 is provided on the upper housing 11, and the display screen 6 is installed in the display window 111. A light-transmitting protective plate 20 is provided on the upper cover of the display window 111 to ensure normal display of the display screen 6 while protecting the display screen 6. Figure 1 As shown, the housing 1 is also provided with necessary power adjustment buttons 112 and switch buttons 142, which can be implemented using solutions known to those skilled in the art, and will not be described in detail here.

[0027] The housing 1 also includes a front cover 13, which engages with the upper housing 11 and the lower housing 12 at their front ends. A light-emitting window 131 is formed on the front cover 13. The upper housing 11, the lower housing 12, and the front cover 13 can be connected and fixed using a snap-fit ​​structure or other similar methods, which can be implemented using solutions known to those skilled in the art and will not be described in detail here.

[0028] Furthermore, such as Figures 2 to 5As shown, the hair removal device includes an inner support 7, which is installed inside the housing 1 and located at one end where the light emission window 131 is located. The lampshade 2 and the light power detection sensor 4 are installed in the inner support 7, and the circuit board 5 is installed on the inner support 7. The inner support 7, installed inside the housing 1 and near the light emission window 131, provides a mounting platform for the lampshade 2, the light power detection sensor 4, and the circuit board 5, thereby improving the stability of the internal structure of the hair removal device.

[0029] Specifically, the inner support 7 includes an upper support 71 and a lower support 72, which are fitted together and form a light emission channel 73 and a mounting cavity 74 sequentially from the end near the light emission window 131. The inner support 7 is divided into an upper support 71 and a lower support 72, which, after fitting together, form a light emission channel 73 and a mounting cavity 74. The fitting method of the upper support 71 and the lower support 72 facilitates modular assembly. The upper support 71 and the lower support 72 are fixed by their respective fastening structures or screws, which can be implemented using methods known to those skilled in the art and will not be described in detail here.

[0030] The light-emitting channel 73 is connected to the light-emitting window 131, and the mounting cavity 74 is connected to the light-emitting channel 73. The lampshade 2 and the optical power detection sensor 4 are installed in the mounting cavity 74, with the lampshade 2 connected to the light-emitting channel 73. The direct connection between the light-emitting channel 73 and the light-emitting window 131 ensures the smoothness of the optical path. The mounting cavity 74 provides a relatively enclosed space for the lampshade 2 and the optical power detection sensor 4, reducing light leakage and external interference to the light source, and improving the detection accuracy of the optical power detection sensor 4.

[0031] Specifically, a sapphire crystal 9 is installed in the light output channel 73. The high light transmittance and stability of the sapphire crystal 9 ensure efficient light transmission, improve the light output effect of the hair removal device, and thus enhance the user experience. Furthermore, the sapphire crystal 9 can effectively reduce the temperature of the skin surface, alleviating pain during hair removal.

[0032] Inside the mounting cavity 74, the lower bracket 72 is provided with a mounting post 721, and a mounting post groove 7211 is opened on the mounting post 721. The optical power detection sensor 4 is installed in the mounting post groove 7211. A sealing post 75 is installed on the mounting post 721 to cover the optical power detection sensor 4. A first opening 7212 is opened on the side of the mounting post groove 7211 near the light output channel 73. The optical power detection sensor 4 is connected to the detection port 21 through the first opening 7212.

[0033] The design of the mounting slot 7211 and the cover post 75 effectively isolates external light and other environmental factors from interfering with the optical power detection sensor 4, ensuring the reliability of the detection results. The mounting slot 7211 also ensures the secure installation of the optical power detection sensor 4.

[0034] like Figure 7As shown, the mounting post groove 7211 has a second opening 7213 on the side opposite to the light emission channel 73. The electrical connection pin 41 of the optical power detection sensor 4 is led out from the second opening 7213, passes through the upper bracket 71, and is electrically connected to the circuit board 5. Specifically, there are two optical power detection sensors 4 arranged side by side, and two detection ports 21 are also arranged accordingly. There are two mounting posts 721 and two capping posts 75, which will not be described in detail here. The capping posts 75 can be glued to the mounting posts 721.

[0035] Mounting post 721 and cover post 75 have mounting limiting grooves 76 on the side near the light emission channel 73. The lampshade 2 is installed between the mounting limiting groove 76 and the connection between the mounting cavity 74 and the light emission channel 73. The limiting groove can limit the lampshade 2, thereby improving the stability of the lampshade 2 installation. Furthermore, limiting ribs 77 can be provided between the upper bracket 71 and the lower bracket 72 corresponding to the lampshade 2. After the upper bracket 71 and the lower bracket 72 are engaged, the lampshade 2 is fixed in the mounting cavity 74.

[0036] The two ends of the lamp tube 3 extend from both sides of the lamp cover 2 and are snapped and soldered onto the conductive plates 30 on both sides of the lamp cover 2. The conductive plates 30 pass through the upper bracket 71 and are soldered to the circuit board 5, thereby realizing the electrical connection between the circuit board 5 and the lamp tube 3, and thus controlling the operation of the lamp tube 3.

[0037] Furthermore, such as Figure 6 and Figure 7 As shown, the hair removal device also includes a cooling fan 8. The air outlet 81 of the cooling fan 8 is connected to the air inlet 741 of the mounting cavity 74. The mounting cavity 74 is also provided with an exhaust port 742, and the housing 1 has an exhaust hole 141 corresponding to the exhaust port 742. The cooling fan 8 can dissipate heat from the mounting cavity 74, reducing the temperature of the working environment of the light power detection sensor 4. Driven by the cooling fan 8, external air is blown into the mounting cavity 74 from the air outlet 81 of the cooling fan 8 through the air inlet 741, and then discharged from the exhaust port 742 and the exhaust hole 141. Specifically, the cooling fan 8 is a turbine fan. Specifically, the switch button 142 and the exhaust port 742 are located on the side shell 14 between the upper shell 11 and the lower shell 12.

[0038] Furthermore, such as Figure 2 and Figure 3 As shown, a heat-conducting plate 10 is installed at the bottom of the lower support 72, and the heat-conducting plate 10 is attached to the lower support 72 and the cooling fan 8. The heat-conducting plate 10 can be made of copper, aluminum, etc. The heat-conducting plate 10 is connected and fixed to the lower shell 12 and the lower support 72 by means of clips or screws, etc., and can be implemented by means known to those skilled in the art, which will not be described in detail here. The attachment of the heat-conducting plate 10 to the lower support 72 and the cooling fan 8 can improve the heat dissipation effect and reduce the overall operating temperature of the hair removal device.

[0039] The heat-conducting plate 10 has a hollow opening 101, and the lower shell 12 has an air inlet 121 corresponding to the hollow opening 101. The air inlet at the bottom of the cooling fan 8 is set to correspond to the hollow opening 101. Outside air enters the turbine fan through the air inlet 121, the hollow opening 101, and the air inlet in sequence, and is then blown into the mounting cavity 74 through the air outlet 81 and the air inlet 741, and is then discharged from the exhaust outlet 742 and the exhaust hole 141.

[0040] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
