Background

In the cultivation process, in order to provide a comfortable growing environment for animals, a heater is generally adopted to maintain the temperature of a farm so as to facilitate the growth of the animals. For example, raising chickens in a greenhouse generally requires that the temperature in the greenhouse be no less than 18 ℃ and no more than 35 ℃. If the temperature is too high, the chicken does not like to move and is not beneficial to growth, and if the temperature is too low, the chicken likes to be crowded and piled, the appetite is not good, the chicken is easy to make sharp calls and is easy to get ill.

The existing heaters mostly adopt gas type infrared ray heaters, and the temperature of the heaters is regulated in two modes, one mode is manual regulation, and the other mode is regulation by adopting a proportional control valve. The manual adjustment is to manually open the size of the air inlet valve to change the supply of the gas quantity, so that the gas and the air are mixed and combusted, and heat is released, so that the purpose of controlling the temperature is achieved, but the manual adjustment has the problems of inconvenience in adjustment, inaccuracy in temperature adjustment, incapability of automatic adjustment and the like; if a proportional control valve is adopted, the control principle of the proportional control valve is to continuously and proportionally control the flow rate, pressure and direction of inlet air according to an input electric signal, so an electric control element, generally an electromagnet, a torque motor and a direct current servo motor, needs to be arranged on the proportional control valve, and all the components need to be driven by an external power supply.
