Description

Technical Field

[0001] This utility model relates to the field of sprayer technology, and in particular to a dual-pump sprayer. Background Technology

[0002] A sprayer is a device that uses air suction to atomize medicine or other liquids into a mist and spray it evenly onto other objects. It consists of a compressed air device and components such as a thin tube and a nozzle. Current sprayers are typically single-bottle designs, unable to handle liquid mixing. Some dual-bottle sprayers only have one pump, requiring the pump to be connected to two inner bottles via a splitting pipe. This can lead to insufficient pump suction, preventing simultaneous liquid absorption from both sides and resulting in uneven mixing. Insufficient sealing at the pump body of existing sprayers also contributes to insufficient suction, requiring the suction tube to be inserted to the bottom of the inner bottle to complete liquid aspiration, negatively impacting the user experience.
