摘要： A spray gun includes a casing (1), a cup (2), a spray nozzle (3), and a pump. The pump is provided in the casing (1) and has a spray chamber in communication with the cup (2). The cup (2) includes a cup housing (21) and a flexible cup body (22) provided in the cup housing (21). A venting structure communicating the cup (2) with an outer environment is provided on the pump. The cup housing (21) is provided with a hollow portion, such that the flexible cup body (22) is manually squeezable to expel air inside the flexible cup body (22) out via the venting structure. In this way, simply squeezing the perforated portion of the flexible cup body (22) enables complete venting of the air present in the flexible cup body (22) via the venting structure. With such configurations, the liquid in the flexible cup body (22) easily enters the inside of the spray chamber, which enables the spray gun to coat stably at a high rate, thereby enhancing operating efficiency of the spray gun.

摘要： This invention provides an electrostatic generation device for an atomizer. It solves the problem of poor spraying effect of the atomizer. When this utility model is used, the fan blows air through the water outlet pipe, and part of the airflow passes through the pressure tube into the water tank, continuously increasing the air pressure inside the water tank. The greater pressure forces the liquid inside the water tank into the inlet pipe and along the inlet pipe into the guide tube, spraying out from the guide tube in the direction away from the fan through the water outlet pipe. The liquid is electrified by the charged metal valve core, and the electrostatically charged liquid is sprayed out through the air outlet, forming electrostatically charged atomized particles. The spray can easily adhere to the object being sprayed, resulting in a higher spraying efficiency.
