This utility model, by installing atomizing nozzles and a storage tank, facilitates the disinfection and sterilization of livestock and poultry breeding sites using a livestock and poultry breeding blower. The pump delivers the disinfectant stored in the storage tank to the supply tank. The disinfectant flowing in the supply tank is then sprayed as a mist through the atomizing nozzles onto the inside of the blower. When the livestock and poultry breeding blower is operating, the flowing air carries the disinfectant into the breeding site, thus facilitating disinfection and sterilization and effectively preventing bacterial growth. However, this utility model has the following problems: Firstly, it lacks a quick installation design. Traditional livestock and poultry breeding blowers are assembled with screws, resulting in slow disassembly and maintenance. Secondly, it lacks a design to prevent dust and insects from entering, leading to dust and insect accumulation inside the blower. Existing insect-proof nets are complex to disassemble, increasing the frequency of maintenance. Utility Model Content
