Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a disinfectant sprayer. Background Art

[0002] In public places such as hospitals, schools, and shopping malls, disinfection is often carried out by spraying disinfectants through sprayers to prevent the spread of pathogens. This is to block the transmission pathways of infectious diseases and thus prevent and control infectious diseases. There are many types of disinfectant sprayers. Some sprayers add gas and pressurize the liquid storage bottle through the piston rod at the top, and then spray the disinfectant through pressure. The spraying effect can be adjusted by adjusting the nozzle.

[0003] The Chinese utility model patent with an application date of 2022-12-07 and a publication number of CN219129610U discloses a disinfectant atomizing sprayer, comprising a base, a plurality of rollers fixedly connected to the bottom of the base, a barrel fixedly connected to the top of the base, and a solenoid valve fixedly connected to the top of the barrel; a feeding pipe is fixedly connected to the top of the solenoid valve, a stirring assembly is provided at the center of the barrel, a pump is fixedly connected to the center of the top of the base, and a feeding pipe is fixedly connected between the pump and the barrel; a feeding pipe is fixedly connected to the top of the outer wall of the pump, a support frame is fixedly connected to one side of the top of the base, an atomizing nozzle is installed at the other end of the feeding pipe, and a fixing assembly is provided between the atomizing nozzle and the feeding pipe; the utility model enables the atomizing nozzle to be disassembled through the setting of the fixing assembly, and the fixing frame can shield the threaded column to prevent the disinfectant from entering the center of the fixed column and causing thread corrosion, and the replacement of the atomizing nozzle is convenient and has a good use effect.

[0004] In this technical solution, the atomizing nozzle is installed on the feeding pipe by means of a fixing column and a threaded column, while the lateral length of the fixing frame is fixed and cannot be adjusted.
