[0031] The utility model aims to solve the problem that the existing irradiation window is inconvenient to replace and install and lacks the automatic identification protection function. Figures 1-8 As shown, the following technical solution is provided: a phototherapy device with an irradiation window, comprising a phototherapy device body 1, wherein the phototherapy device body 1 includes a light source module, a heat dissipation module, a drive control board module and a power supply module, and also includes an irradiation window 2, which is detachably arranged at a position corresponding to the light source module on one side of the phototherapy device body 1, and a light outlet 24, a first magnetic group 21 and a sensing component 3 are provided in the middle of the irradiation window 2, and the phototherapy device body 1 is provided with a second magnetic group 16 adsorbed with the first magnetic group 21, and a sensing detection circuit 4 is provided at a position corresponding to the sensing component 3 on the phototherapy device body 1, and the sensing detection circuit 4 is electrically connected to the drive control board module, and by arranging the first magnetic group 21 and the second magnetic group 16, the irradiation window 2 can be quickly and accurately installed on the phototherapy device body 1, thereby solving the problem of quick replacement and installation of the irradiation window 2, and by arranging the sensing component 3 and the sensing detection circuit 4, the position of the irradiation window 2 can be self-identified, which can protect the skin and is safer when used.

[0032] Specifically, the light therapy device body 1 includes a light source module, a heat dissipation module, a drive control board module and a power supply module, all of which are existing technologies.

[0033] The irradiation window 2 is a modular component. The shapes of different irradiation windows 2 and the positions of the first magnetic attraction group 21 are consistent. The main difference lies in the shape and size of the light outlet 24. Figure 6As shown, the shape of the light outlet 24 is circular or oval or rectangular, which can be quickly replaced according to needs. Specifically, the light outlet 24 can be a square hole with a size of 25mm*25mm, a circular hole with a diameter of 15mm, and an oval hole with a long axis of 24mm and a short axis of 16mm.

The boss 22 facilitates alignment of the skin during irradiation, and the mirror surface reflection structure can improve the reflection efficiency of the inner wall of the window on light, and reduce the attenuation of the output intensity of the light source due to the height difference of the boss. The mirror surface reflection structure can be a mirror surface aluminum sheet or an electroplated aluminum film process structure, which can be selected according to needs.

[0041] As shown in Figure 2 The angle α between the display screen 13 and the irradiation window 2 is 12-18°, preferably 14°, and the angle in the range facilitates the user to hold the product to perform the irradiation treatment on the affected skin and observe the interface information of the display screen, and conforms to the ergonomic concept.

[0042] As shown in Figures 1-3 The side of the light therapy head 11 is provided with a heat dissipation hole 15 corresponding to a heat dissipation module, and the handle 12 is provided with a switch button 14 at the position combined with the light therapy head 11.
