Description

Technical Field

[0001] The utility model relates to the technical field of sprayers, in particular to a sprayer with a dual water inlet channel. Background Art

[0002] A sprayer is a common and practical tool with various uses and types. For example, it can evenly spray pesticides in paddy fields to control rice pests and diseases, and can also be used to water and fertilize flowers and vegetables so that nutrients can be evenly distributed. It can spray disinfectant solution to disinfect public places to prevent the spread of diseases. After the sprayer is used, the remaining liquid medicine needs to be disposed of in time. Otherwise, it is impossible to spray clean water to clean the spray gun, water pipe and water pump water-passing parts of the sprayer. The long-term residue of the liquid medicine in the spray gun and water pump parts will damage the machine. The traditional cleaning method is to pour out the remaining liquid medicine and store it separately in another container, and then use clean water to clean each part of the sprayer to drain the remaining corrosive liquid medicine in time.

[0003] Patent No. CN219400650U proposes a backpack sprayer, which includes a backpack sprayer body, a driving motor and an atomization pump. The top of the backpack sprayer body is provided with a feeding port, and the surface of the feeding port is provided with a sealing cover. The front of the backpack sprayer body is provided with a shoulder strap. A driving motor is installed inside the backpack sprayer body. A first transmission wheel is fixedly installed on the output shaft of the driving motor. A transmission belt is installed on the surface of the first transmission wheel. By providing a first stirring rod and a second stirring rod, the rotation of the driving motor can make the first stirring rod and the second stirring rod rotate simultaneously. Through the rotation of the first stirring rod and the second stirring rod, the liquid in the backpack sprayer body can be continuously stirred to prevent the undissolved solid medicine powder from precipitating.

[0004] However, the technical solution of this patent cannot quickly switch between clean water and liquid medicine, and cannot quickly clean the water passing of the nozzle, water pump and connecting pipeline.

[0005] Therefore, those skilled in the art provide a sprayer with a dual water inlet channel to solve the above problems. Summary of the Utility Model
