[0002] A clothes dryer is a household appliance that uses electric heating to instantly evaporate and dry the moisture in washed clothes. The working principle of a clothes dryer is to use a heating element to generate heat inside the dryer, thereby evaporating and drying the moisture in the clothes. Although this type of clothes dryer can dry clothes, some bacteria may not be killed because the clothes are not exposed to sunlight, and the drying effect is not as good as normal sunlight. Therefore, some clothes dryers that can disinfect clothes have appeared on the market, but their structures are generally complex, and production, assembly and subsequent maintenance are relatively troublesome. The actual use effect is poor, and the user experience is not good. Utility Model Content

[0006] The base frame is arranged in an arc shape, and an extension portion is arranged on the base frame near the heat sink. The extension portion is provided with a heat dissipation port communicated with the inner side of the base frame.

[0007] The inner side of the base frame is arranged with reinforcing ribs and clamping grooves.

[0008] The inner wall of the lamp cover is provided with a first snap-fitting protrusion near its bottom, the outer wall of the lamp holder has a protrusion extending obliquely outward, the first snap-fitting protrusion can be abutted against the end of the protrusion, the inner wall of the lamp cover is also provided with a first guide rib, and the outer wall of the lamp holder is provided with a first guide groove that cooperates with the first guide rib.

[0009] A cylindrical portion is integrally provided on the lamp holder, a second guide groove is provided on the outer side of the cylindrical portion, a second guide rib is provided on the outer side wall of the lamp tube, the second guide rib is inserted into the second guide groove, and a second clamping protrusion is also provided at the end of the lamp holder, and the second clamping protrusion is abutted against the bottom of the lamp tube.
