Abstract
The utility model relates to a jet type spray gun, which comprises a liquid tank and a gun body. A jet tube and a trigger used for opening and closing the jet tube are arranged on the gun body; the utility model is characterized in that the utility model is provided with a liquid channel which has the same direction of the air flow with the jet tube; one end of the channel is communicated with the liquid tank, and the other end is communicated with the air channel of the jet tube near the outlet end of the jet tube along the flow jetting direction. The utility model can better approach the deeper and the narrow places of working pieces, the utility model can particularly extend into the containers with smaller caliber to spray, and thus, the spraying and coating parts have better spraying and coating effect.
Description
The utility model relates to a kind of injection apparatus, particularly by Compressed Gas with the jetting type spray gun of liquid spray on object.
General spray gun paint can upper end paint spray nozzle mouth is provided with air nozzle, pressure-air by air nozzle along the paint spray nozzle bore to injection because suction function, the coating (paint) in the paint can is drawn and is sprayed on the object by the pressure-air of continuous injection.In order to prevent that coating cloud from not floating to diffusion all around, Chinese patent application 90205509.7 provides a kind of coating cloud indiffusion spray gun, and it is provided with an air curtain shroud ring at jet, in painting process, pressure-air outwards sprays and forms a coniform gas hood, and coating cloud is covered firmly.But, because the nozzle of above-mentioned spray gun is near the paint can upper end, to workpiece particularly cave in more deeply, the proximity at narrower position is poor, spraying effect is bad.
The purpose of this utility model provides a kind of jetting type spray gun, it can near workpiece depression more deeply, narrower position, make position to be coated with that spraying effect preferably be arranged.
The technical solution of the utility model is: a kind of jetting type spray gun, comprise flow container, rifle body, the rifle body is provided with air jet pipe and opens and closes the trigger of air jet pipe, its special character be provided with one with air jet pipe air-flow fluid passage in the same way, one end of this passage is connected with flow container, and the other end is being connected with the air flue of air jet pipe near the air jet pipe port of export along the drainage direction.
And the fluid passage is the space that is located between the sleeve pipe on the air jet pipe and the air jet pipe outside.Perhaps fluid passage is the pipeline that is located near the liquid pipe in the air jet pipe outside.
The utility model since be provided with one with air jet pipe air-flow fluid passage in the same way, make nozzle away from flow container, thereby can be better, narrower region dark near the workpiece depression, particularly can put in spraying in the more small-bore container, make the spraying position that spraying effect preferably be arranged.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structure chart of the utility model embodiment one.
Fig. 2 is that jetting type spray gun shown in Figure 1 is along A-A line profile.
Fig. 3 is the local diagrammatic sketch of the utility model embodiment two.
Embodiment one: as shown in Figure 1, the flow container 12 of jetting type spray gun is fixedly connected on rifle body 1 by cover 11, air jet pipe 4 on the rifle body 1 is with rifle body 1 thread connection or be processed into one, air jet pipe air flue 5 and rifle body air flue 3 are communicated with and connect with pressure-air by the pneumatic fitting 2 of rifle body 1 afterbody.3 imports of rifle body air flue are provided with the trigger 13 of control air inlet.Air jet pipe 4 has certain elongation and is arranged in the sleeve pipe 6 in the spraying direction, with sleeve end thread connection away from the spraying mouth, space between sleeve pipe 6 and the air jet pipe 4 is a fluid passage 7, this passage 7 is communicated with flow container 12 by suction pipe 10, and be communicated with air flue 5 in air jet pipe 4 outlet, through the nozzle 8 that being located at herein at last and lead to the external world.Nozzle 8 thread bush are connected on the sleeve pipe 6, and air jet pipe 4 ports of export are fixed on (referring to Fig. 2) on the nozzle 8 by locating ring 9.
Embodiment two: referring to Fig. 3, establish the sleeve pipe 6 in a liquid pipe 14 alternate embodiments one near air jet pipe 4 outsides.The pipeline 15 of liquid pipe 14 is a fluid passage, and an end is communicated with flow container 12, and the other end is communicated with air flue 5 near nozzle 8.
The utility model course of work is as follows: after connecting pressure-air, open plate machine 13, pressure-air is through air flue 3,5 ejections, produce negative pressure at fluid passage 7,15 ports of export simultaneously, coating in the flow container 12 (paint) is drawn and is smashed atomizing by the pressure-air of continuous injection, is sprayed on the object through nozzle 8 at last.
