Abstract

The utility model relates to an electric spray gun for spraying liquid, comprising a liquid storing bottle, an infusion tube, a pump body, a spray head, a vibrator, a regulator, a handle, etc. The inner part of the pump body is provided with a pump piston and a disperser; the armature iron of the vibrator is clamped between the pump piston and the regulator; the pump piston is sheathed with a reset spring; when the vibrator works, the armature iron can generate high-frequency vibration; the pump piston is pushed to conduct the reciprocating movement, and the liquid in the pump body can be ejected outwards through the disperser and the spray head. The utility model which can be used for spraying all kinds of coatings, the repairing of automobiles, the painting of the furniture, and other aspects in the building trades has the advantages of simple structure, convenient operation, small size, low cost, etc.

Description

Electric spray gun

The utility model relates to the liquid spray technical field of tools.

At present, the instrument that is used for liquid spray generally is divided into two kinds, and a kind of is with electric air compressor, gas bomb, utilizes compressed air, liquid such as spray paint; Another kind is with the artificial air accumulator compressed air of giving, and utilizes the air pressure spraying liquid of air accumulator, is used for the spraying of construction wall mostly, the former cost height, volume are big, are fit to use of large-scale production, the latter need with artificial compressed air, time-consuming, require great effort, spraying effect is relatively poor, uses inconvenience.

The purpose of this utility model provides a kind of simple in structure, easy to use, volume is little, cost is low electric spray gun.

The utility model is achieved in that and is provided with the pump housing in spray gun, the bottom of the pump housing is connected with woven hose, vibrator is equipped with on the top of the pump housing, the armature lower end of vibrator places between pump plug and the adjuster and touches, be socketed with back-moving spring beyond the Great Wall at pump, this vibrator energising back armature produces dither, and the pump plug is under the promotion of armature, under the effect of back-moving spring, produce high frequency and move back and forth in the pump housing, the liquid that promotes in the pump housing outwards sprays.For making the liquid in the liquid storage bottle can suck the pump housing, and when spraying, produce atomizing effect preferably, one disperser is housed in the pump housing, this disperser is connected with jacking block respectively and is disperseed piece by both ends of the spring, be laid with 3 spray orifices on this dispersion piece, the effect of disperser jacking block is when the pump plug retreats under action of reset spring, by jacking block with closed front in the pump housing, make and produce negative pressure in the pump housing, with the liquid in the liquid storage bottle, suck in the pump housing by woven hose, the pump plug is under the promotion of armature, push the liquid in the pump housing to shower nozzle, 3 spray orifices on the disperser are that liquid is evenly sprayed in 3 spray orifices; For making the liquid jet atomization better, in shower nozzle, be connected with a nozzle core, the nozzle core center is provided with the umbrella shape hole, by the liquid that disperses 3 spray orifice ejections on the piece, produce the liquid particle preferably that atomizes behind the umbrella shape hole, and jet length is far away.

The utility model compared with the prior art, have simple in structure, easy to use, volume is little, low cost and other advantages.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation

Fig. 2 disperses the piece schematic diagram

Fig. 3 is that Fig. 2 A-A is to schematic diagram

Fig. 4 is the shower nozzle schematic diagram

Referring to accompanying drawing: the pump housing 10 is housed in spray gun, the pump housing 10 bottoms are connected to woven hose 2, woven hose 2 lower ends are connected to filter 1, woven hose 2 and filter 1 place in the liquid storage bottle 3, one vibrator 9 is housed on the top of the pump housing 10, be made of electromagnetic core, armature 12 lower ends of vibrator 9 are clipped between adjuster 14 and the pump plug 13 and touch, and are socketed with back-moving spring 11 on pump plug 13; Disperser 4 also is housed in the pump housing 10, and this disperser 4 is connected with jacking block 8 respectively and is disperseed piece 6 to constitute (see figure 1) by spring 7 two ends, is laid with 3 spray orifice 18(and sees Fig. 2, Fig. 3 on dispersion piece 6); For improving jeting effect, in shower nozzle, be connected with a nozzle core 19, nozzle core 19 centers are provided with a umbrella shape hole 20(and see Fig. 4).During actual the use, grasp handle 17, Push switch button 16, vibrator 9 work produce high frequencies by 12 pairs of pump plugs of armature 13 and promote, and according to instructions for use, rotation regulator 14 knobs 15 can be regulated the size of liquid emitted dose.

Claims
