Energy-saving handheld spray gun capable of solving problems of spray hole blockage and needing to remove dust in advance

Abstract

The invention relates to the technical field of interior decoration design, and discloses an energy-saving handheld spray gun capable of solving the problems of spray hole blockage and needing to remove dust in advance. Through cooperative use of a vertical rod, a swing rod, a rotary disc, a threaded rod and a rotary knob, spraying is more compact and uniform, and meanwhile, the spraying capacityin unit time can be changed, and the spray gun is more intelligent. Through cooperative use of a mixing chamber, a roller shaft, a negative pressure chamber, a first baffle and a second baffle, an ashlayer on a coating surface is automatically blown away through compressed gas before spraying, more time and labor are saved, residual paint in spraying holes can be taken away after spraying is finished, paint waste is reduced, the spraying holes are prevented from being blocked. Through cooperative use of the button, a first push rod, a second push rod and the rotary knob, manual control is facilitated, and when the spraying position needs to be changed, a power source does not need to be repeatedly turned off for control, and large energy consumption caused by repeatedly turning on and offthe power source is avoided.

Description

technical field [0001] The invention relates to the technical field of interior decoration design, in particular to an energy-saving hand-held spray gun that solves the clogging of spray holes and requires dust removal in advance.

[0002] With the improvement of people's living standards, whether it is a family, a company, or some public places, in order to increase the aesthetics, the interior decoration design is usually carried out, and the spraying of wall paint is one of the most common ways to achieve protection. For the purpose of wall and beautifying the indoor environment, in the process of spraying paint, spray guns are usually used for operation. However, the existing spray guns have great limitations in use. On the one hand, in order to improve the adhesion of paint , Before spraying, it is necessary to manually remove the dust layer attached to the sprayed surface, and it is impossible to automatically remove the dust, which is time-consuming and laborious. On the other hand, when the spray gun is used, due to the small spray hole, there will be more residue in the spray gun after spraying The paint will not only cause waste of paint but also cause the nozzle hole to be easily clogged
