Description

Technical Field

[0001] This utility model relates to a high-intensity pulsed light therapy device, and more particularly to a high-intensity pulsed light therapy device with replaceable filters. Background Technology

[0002] There are many types of intense pulsed light (IPL) therapy devices, including hair removal devices that use intense pulsed light to irradiate the skin for hair removal, and products that use light of a specified wavelength to irradiate the skin for treating skin diseases or skin rejuvenation. For relevant prior art, please refer to the Chinese patent publication CN220876901U entitled "Intense Pulsed Light Therapy Device," which describes: "The intense pulsed light therapy device 10 includes a contact 600 connected to a housing 100 and a cooling component 700 disposed within the housing 100. The contact 600 may include a contact portion 610 and a crystal 620 connected to the contact portion 610. The crystal 620 passes through the contact portion 610 and is used for light emission from the light source component 200. The crystal 620 may be sapphire and is used to filter harmful light rays such as ultraviolet rays. The crystal 620 may be connected to the cooling component 700." In this type of intense pulsed light therapy device, the contact element and the crystal are directly fixed to the front end of the housing, making it difficult to disassemble and replace the contact element and the crystal. In practical applications, only a product design with wide-band full coverage can be selected, which increases the damage to the skin caused by useless wavelengths. Even if an auxiliary lamp head is added, the energy density will be reduced, and the expected effect will not be achieved. Utility Model Content

[0019] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0020] This utility model discloses a high-intensity pulsed light therapy device with replaceable filters, combined with... Figures 1 to 5 As shown, it includes a housing 1 and an end cap 2. The front end of the housing 1 is provided with a plug-in part 12, and the front end of the plug-in part 12 is provided with an assembly port 10. A light source assembly 11 is provided in the assembly port 10. The housing 1 is provided with a host for controlling the light source assembly 11 to emit strong pulse light. The end cap 2 covers the outside of the plug-in part 12 and the two are detachably connected. The end cap 2 is provided with a front frame 3, a rear frame 4 and a filter 5. The front frame 3 and the rear frame 4 are stacked one behind the other and are detachably connected. The filter 5 is sandwiched between the front frame 3 and the rear frame 4. The front frame 3 is located in the front port 20 of the end cap 2 and the front frame 3 is detachably connected to the front port 20.

[0021] In the above structure, the housing 1 serves as both a handle and a container for the main unit. The main unit includes components such as a discharge capacitor, circuit board, buttons, and a fan. Under the action of the main unit, the light source assembly 11 can be controlled to emit light of a specified intensity and wavelength. Furthermore, the end cap 2 and the plug-in part 12 are in a sleeve relationship and can be detached and installed. When the user needs to replace the filter, the end cap 2, together with the assembly consisting of the front frame 3, the rear frame 4, and the filter 5, can be removed. Then, the front frame 3, the rear frame 4, and the filter 5 can be disassembled to replace the filter 5. Compared with the prior art, the process of replacing the filter in this utility model is simple and convenient, which helps users to quickly and easily replace filters of different wavelengths, thereby meeting multiple functional requirements and effectively avoiding damage to the skin caused by useless wavelengths.

[0022] It should be noted that the above-mentioned detachable installation methods in this utility model include magnetic attraction, column hole insertion, and snap-fit ​​connection, etc. Specific embodiments are provided below to illustrate the preferred detachable installation method of this utility model.

[0023] For easy removal and assembly of the end cap 2, please refer to [link / reference]. Figure 4 and Figure 5 The end cap 2 has a first magnet 21 embedded on its left and right sides, and the insertion part 12 has a second magnet 13 embedded on its left and right sides. The first magnet 21 and the second magnet 13 correspond one-to-one and are magnetically attracted to each other. The magnetic attraction method has the function of automatic adsorption and automatic alignment, which can improve the convenience of user replacement operation. In addition, a snap-fit ​​method can also be used, but magnetic attraction is preferred.

[0024] Regarding the detachable connection method between the front frame 3 and the rear frame 4, please refer to [link / reference] in this embodiment. Figure 2 The rear frame 4 has multiple insertion posts 40 on its front side, and the front frame 3 has multiple insertion holes on its rear side. Each insertion post 40 corresponds to one insertion hole, and the two are interlocked. Because the end faces of the front and rear frames are relatively narrow, an insertion-matching method is suitable. This embodiment, based on the insertion-matching method of the insertion posts 40 and the insertion holes, facilitates the assembly of the front frame 3 and the rear frame 4, making it convenient for users to operate independently. However, in practical applications, it is not limited to insertion or magnetic matching methods.

[0025] To better fit the filter 5 and ensure a good fit between the front frame 3 and the rear frame 4, in this embodiment, please refer to... Figure 1 The front opening edge of the rear frame 4 is provided with a stepped groove 41, and the filter 5 is embedded in the stepped groove 41.

[0026] In this embodiment, the assembly consisting of the front frame 3, the rear frame 4, and the filter 5 is detachably installed inside the end cap 2. For the specific installation method of this assembly, please refer to [link to relevant documentation]. Figure 3 The front frame 3 has protruding buckles 30 at its upper and lower ends, and the inner wall of the front port 20 has snap-fit ​​slots 22 at its upper and lower ends. The protruding buckles 30 and the snap-fit ​​slots 22 correspond one-to-one, and the protruding buckles 30 are engaged within the snap-fit ​​slots 22. However, in practical applications, the method is not limited to snap-fit ​​or magnetic engagement.

[0027] To limit movement and prevent the front frame 3 from detaching from the front port 20, in this embodiment, a stepped edge 31 is formed on the edge of the front frame 3, which engages with the inner wall of the end cap 2. Furthermore, a sensing coil 6 is sandwiched between the stepped edge 31 and the inner wall of the end cap 2. The sensing coil 6 can be electrically connected to a circuit board via FPC strip or wires to transmit skin sensing signals.

[0028] To better match the housing 1, in this embodiment, the front frame 3 and the rear frame 4 are embedded within the assembly opening 10. Based on this matching relationship, it can be ensured that the filter 5 and the light source assembly 11 are accurately aligned.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
