[0028] By setting two heating sheets 4, they can fully contact the two side walls of the mosquito repellent sheet 19, thereby improving the heating efficiency, fully evaporating the mosquito repellent components in the mosquito repellent sheet 19, and improving the utilization rate of the mosquito repellent sheet 19. In addition, first vent holes 7 are set on both sides of the heating sheet 4, so that the gas generated by the mosquito repellent sheet 19 can be discharged from the first vent holes 7, thereby achieving a good insect repellent effect.

[0029] The first ventilation holes 7 on the left heating plate 4 and the first ventilation holes 7 on the right heating plate are arranged in a staggered manner.

[0030] The heating unit 3 also includes an insulation plate 8, two insulation plates 8 are provided, and the insulation plates 8 are respectively installed on the side of the two heating plates 4 away from each other. Each heating plate 4 is provided with a plurality of first ventilation holes 7 penetrating therethrough, and each insulation plate 8 is provided with a plurality of second ventilation holes 9 corresponding to the positions of the first ventilation holes 7 of the heating plate 4 on the same side, and the second ventilation holes 9 penetrate the insulation plate 8. By providing the insulation plate 8, heat loss can be avoided, energy consumption can be reduced, the rechargeable battery can be more power-saving, the evaporation effect of the mosquito repellent plate 19 is ensured, and it is more suitable for outdoor environments. In addition, the first ventilation holes 7 and the second ventilation holes 9 are respectively provided on the heating plate and the insulation plate 8 to facilitate the dissipation of the evaporated mosquito repellent gas and improve the mosquito repellent effect.

[0031] It also includes a mounting base 10 for fixing the heating unit 3, and the mounting base 10 includes an upper base 11, a lower base 12 and a pressing plate 13. Two pressing plates 13 are provided and are respectively located on both sides of the upper base 11 and the lower base 12. A window 14 for installing the heating unit 3 is formed between the upper base 11, the lower base 12 and the pressing plate 13. Each pressing plate 13 is provided with a number of third ventilation holes 15 corresponding to the positions of the second ventilation holes 9 of the insulation board 8 on the same side. The purpose of providing the third ventilation holes 15 is also to facilitate the dissipation of odors.

[0032] Grooves 16 are provided on both sides of the upper base 11 and the lower base 12. The upper and lower ends of the heating plate 4 and the insulation plate 8 are at least partially confined in the grooves 16. The upper and lower ends of the pressing plate 13 are respectively connected to the upper base 11 and the lower base 12, and the pressing plate 13 is located on the outside of the insulation plate 8 to limit the heating plate 4 and the insulation plate 8 from escaping from the grooves 16.
