Abstract

The invention discloses a manual vacuum paint can. A paint storage chamber and an airtight chamber are formed in a can body; a return gas connecting pipe, a paint conveying connecting pipe and a pouring port are arranged over the paint storage chamber; a manual vacuum is arranged at the pouring port; a cup-free paint gun is provided with a return gas pipe joint communicated with a high-pressure air inlet pipe and a paint conveying pipe joint communicated with a nozzle; a return gas pipe is connected with the return gas connecting pipe at the top of the paint storage chamber; and a paint conveying pipe is connected with the paint conveying connecting pipe. Paint spraying operation can be directly performed by connecting the paint conveying pipe and the paint conveying pipe joint of the cup-free paint gun and connecting the return gas pipe and the return gas pipe joint of the cup-free paint gun. Therefore, the paint gun does not need a spraying cup any more; the work of pouring paint into the spraying cup before paint spraying operation and washing the spraying cup after the paint spraying operation is eliminated; the working time can be saved; the labor intensity of operation workers is reduced; the working efficiency is improved; a thinner used for washing the spraying cup is saved; and pollution of the thinner which has washed the spraying cup to the environment is prevented.

Description

technical field [0001] The invention relates to a paint can, especially a manual vacuum paint can, and also relates to a cupless paint spray gun. Background technique [0002] Existing paint is usually filled in iron barrels or plastic barrels. When spraying paint, the operator needs to open the paint barrel or paint can, pour the paint into the spray cup, and then perform the painting operation. Sometimes, the paint and curing agent must be prepared in advance before being poured into the spray cup for painting. This kind of painting operation method is time-consuming and laborious. After the painting operation is completed, the spray cup must be cleaned with thinner, otherwise the spray cup can no longer be used, and thinner after use can often not be reused, resulting in waste of thinner, and the drained thinner is reused It will pollute the environment, and the work of cleaning the spray cups will also increase the workload of the operators. In addition, if the paint ...
