[0002] A sprayer is a mechanical device for agricultural and forestry plant protection, which is widely used for antifreeze, insecticide, disinfection and sterilization or fertilization. Sprayers include foggers and steam sprayers. Foggers mix agents and additives and then heat them for spraying. Patent document CN117480983A discloses a novel method and device for crop fog frost prevention, wherein a heating element in a novel crop fog frost prevention device includes a burner. In some areas where there is sufficient supply of environmentally friendly vegetable oil wax (liquid), the environmentally friendly vegetable oil wax is passed through a steel pipe into a combustion chamber (2) in the antifreeze device (1), and the steel pipe is heated by the burner. The liquid oil wax passes through the steel pipe, generates heat and atomizes, and forms a large amount of fog. In the patent, the heating surface is single, and the heating efficiency of the oil wax is not high. When a large amount of oil wax enters the steel pipe, it is easy to produce insufficient atomization, which affects the atomization effect. Therefore, a sprayer combustion chamber is needed to solve the above technical problems. Utility Model Content
