[0032] The above solution will be further described below with specific embodiments. It should be understood that these embodiments are for illustrative purposes only and not for limiting the scope of the present application. The implementation conditions used in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually those in conventional experiments.

[0033] This application proposes a new type of intelligent mosquito-catching device based on radiative cooling thermoelectric power generation (hereinafter referred to as the device). It uses a shutter-type intelligent switch anti-escape device to trap mosquitoes and kill the trapped mosquitoes by high-temperature means. The anti-escape device includes: a stepper motor, and the output end of the stepper motor is connected to the shutter blades, and the blades are rotated to open or close based on the drive of the stepper motor. When the mosquito-catching device is in the mosquito-killing mode, the control unit outputs a signal, the stepper motor rotates, and then drives the blades to rotate to close, and the PTC heating plate starts to work. In this embodiment, the degree of opening and closing of the blades (blade opening state and closing state) is achieved by controlling the number of turns of the stepper motor. The control unit uses an STM32F103 chip. When killing mosquitoes, the PTC heating water method is adopted. Among them, the water is collected by the condensate device. The cold end of the thermoelectric sheet is a radiative cooling material, which is lower than the ambient temperature and has a certain inclination angle. Using different temperature differences, the water in the air is condensed. The condensed water enters the groove through the radiative cooling film, is collected by the groove and enters the water tank through the pipeline to provide a water source. During heating, the controller controls the photocatalyst lamp tube to turn off through the isolation module, and the power supply only supplies power to the PTC heating plate to stabilize its voltage and improve efficiency. After heating, the internal temperature of the mosquito catcher exceeds the survival temperature range of mosquitoes (10°C - 40°C), causing them to die slowly. At the same time, the internal environmental temperature rises, and the hot end temperature of the thermoelectric sheet rises accordingly, bringing a greater temperature difference and output voltage, which can further stabilize the operation of the heating plate, recycle the energy, and improve the device efficiency.

[0034] The working principle and working process of the above device are as follows:

[0035] During the daytime (e.g., 6:00 - 18:00), since the effect of the photocatalyst lamp tube is not obvious and the temperature difference of the thermoelectric sheet is low, the power supply only supplies power to the control unit, and its internal clock register starts timing. During the night (e.g., 18:00 - 23:00), at this time the shutter blades are in the open state, the power supply module is electrically connected to the photocatalyst lamp tube and the control unit and supplies power to them. At this time, the photocatalyst lamp tube converts harmful gases in the air into substances such as carbon dioxide, thus attracting mosquitoes. The initial inclined state of the blades blocks the escape of mosquitoes to a certain extent. During the early morning (e.g., 23:00 - 5:00), the control unit issues a motor control signal to make the stepper motor rotate according to a certain number of turns, so that the shutter blades are in the closed state. At this time, the photoelectric coal lamp tube is turned off, and the power supply supplies power to the PTC heating plate and the control unit. By heating the water to the steam state, the internal environmental temperature rises. The mosquitoes are in a closed state and cannot escape and are killed. During use, the staggered use of electrical equipment also ensures the stability of the voltage.

[0036] The condensate device is in an all-weather working state. When the water vapor in the air encounters the radiation cooling film with a lower temperature, liquefaction occurs, and then it flows into the water tank through the groove for water storage. At the same time, a pipeline can be connected to the upper part of the water tank wall to the outside of the mosquito trap, so as to effectively prevent excessive water storage caused by rainy weather or other situations. While realizing green environmental protection, this device can attract mosquitoes to the greatest extent and achieve the effect of mosquito trapping.
