Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, and more specifically, to a portable handheld spraying equipment. Background Art

[0002] Spraying equipment is a product of the increasingly common environment of industrial technology development and automation after the reform and opening up. Spraying equipment is mainly used to protect the surface of objects and has many fields of use. Spraying equipment is also divided into manual sprayers, automatic sprayers, semi-automatic spray guns, manual spray guns and other types.

[0003] For example, the authorization announcement number CN 217222002 U discloses a household handheld automatic spraying device, which seals the gun body and the bottle body by setting a sealing gasket, adsorbs the first magnet by the second magnet, and allows the fixed frame to drive the hose to remain vertically fixed. When the switch is turned on, the micro water pump draws the paint out through the hose and draws it into the interior of the fixed pipe through the connecting pipe, so that the paint is sprayed out through the nozzle, which is convenient for filtering the water solvent injected into the equipment. Long-term use is not easy to cause internal blockage of the equipment. At the same time, the internal pipes of the equipment are not easy to bend, which does not affect the spraying of the equipment.

[0004] In the above scheme, the hose is fixed by a magnet to keep the hose vertically fixed. However, since the hose is fixed, when the solvent inside the device is extracted, the solvent at the bottom layer inside the device cannot be extracted, resulting in a waste of solvent. In addition, when the unused solvent is placed in the device for a long time, the solvent precipitates and causes uneven distribution. This situation will also cause blockage of the hose, affecting the use effect of the device. Utility Model Content

[0008] A stirring device is provided in the storage barrel, and the stirring device includes a waterproof motor and a stirring blade. The waterproof motor is placed inside the storage barrel, and the waterproof motor is electrically connected to a controller, and the controller is arranged on the outer wall of the storage barrel. The stirring blade is connected to the output end of the waterproof motor.

[0009] The stirring blade includes a stirring rod and a plurality of blades. The blades are arranged on the outer peripheral wall of the stirring rod. The stirring rod has a cavity inside for inserting a hose. A positioning block is arranged on the lower end surface of the storage barrel.
