Handheld wall paint spraying device with coating amount convenient to adjust

Abstract

The invention discloses a handheld wall paint spraying device with the coating amount convenient to adjust, and relates to the technical field of paint spraying. The handheld wall paint spraying device used in a house comprises a handheld spraying gun body, wherein a hose is installed on a bottom flange of the handheld spraying gun body; the discharging end of the hose communicates with the interior of the handheld spraying gun body; the feeding end of the hose communicates with the outside; a spraying hopper is installed on a front side flange of the handheld spraying gun body, an adjusting mechanism is arranged on the handheld spraying gun body, a connecting pipe is installed on the bottom flange of the handheld spraying gun body, and the connecting pipe communicates with the interior ofthe handheld spraying gun body; and a tank body is arranged below the handheld spraying gun body, the tank body and the connecting pipe are arranged in a matched threaded connection mode, a feeding pipe is installed on an outer wall flange of one side of the tank body, and the feeding pipe communicates with the interior of the tank body. According to the handheld wall paint spraying device, solidification of sprayed paint can be prevented, the situation that the spraying effect is influenced due to solidification of the sprayed paint is avoided, the spraying quality is improved to a certain extent, and the handheld wall paint spraying device is better in spraying quality than a traditional mode.

Description

technical field [0001] The invention relates to the technical field of painting, in particular to a hand-held wall painting device for conveniently adjusting the amount of painting. Background technique [0002] Walls mainly include load-bearing walls and non-load-bearing walls, which mainly play the role of enclosure and space separation. Walls of load-bearing structure buildings combine load-bearing and enclosure. The role of walls in skeleton structure systems is to enclose and separate spaces. , the wall must have sufficient strength and stability, and have the ability of heat preservation, heat insulation, sound insulation, fire prevention, and waterproof. There are many types of walls, such as walls with single materials and walls with composite materials. Considering factors such as enclosure, load-bearing, energy saving, and aesthetics, designing a reasonable wall scheme is an important task of building construction.

Problems solved by technology

[0003] Spraying through a spray gun or disc atomizer, with the help of pressure or centrifugal force, disperses into uniform and fine droplets, and applies the coating method on the surface of the object to be coated, which can be divided into air spraying, airless spraying, electrostatic spraying and Various derivations of the above-mentioned basic spraying forms, such as large-flow low-pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc., modern human life will carry out wall surface decoration for the sake of aesthetics and use effect. For painting treatment, the traditional hand-held spray gun has a single structure, which is not conducive to the adjustment of spray volume; and the spray material will also solidify if it is not used for a long time, which reduces the effect of spray painting to a certain extent, which is not conducive to popularization and use
