Description

Technical Field

[0001] The utility model relates to the technical field of electric spray guns, and particularly relates to an electric spray gun. Background Technique

[0002] An electric spray gun is an electric tool that sprays various low-viscosity liquids into a mist. It uses an electromagnet to drive an armature, which acts on a piston rod to perform high-speed reciprocating motion, forming a siphon phenomenon, sucking the liquid up from the container; at the same time, high pressure is formed and sprayed out from the nozzle at high speed and atomized, adhering to the surface of the object to complete the spraying process. The electric spray gun drives the mechanical device inside the spray gun through an electric motor, so that the paint is sprayed out from the nozzle under pressure. Its working principle mainly includes the following steps: Connect the paint to the inlet of the spray gun through a pipeline or container. The electric motor drives a pump or other pressure generating device to make the paint form a certain pressure inside the spray gun. Under the action of the pressure, when the paint is sprayed out through the nozzle, it mixes with air to form fine mist particles. The mist-like paint particles are sprayed onto the target surface to form a uniform coating.

[0003] In the use of the existing electric spray gun, generally, a raw material tank containing paint is installed on the surface of the gun body of the spray gun, and then the raw materials are extracted by the spray gun for spraying. However, the existing raw material tank and the spray gun are fixed by threaded connection. In the actual use process, due to the vibration of the spray gun itself and the movement of the operator moving the spray gun, the raw material tank is prone to deflection, and then the connection becomes loose, causing the raw material tank to fall off, reducing the practicability.

Specific implementation manners

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figure 1-6 , the present utility model provides a technical solution: an electric spray gun, including a spray gun body 1, a connecting pipe 2, a raw material tank 3, a support connection column 4, a positioning ring 5, a transmission disc 6, an adjusting lead screw 7, a damping cylinder 8, an air guide piston head 9, a connecting air groove 10, a transmission piston column 11, a friction pressure plate 12, an air guide hose 13 and an anti-slip suction cup 14. One end of the lower surface of the spray gun body 1 is fixedly installed with a connecting pipe 2. A raw material tank 3 is arranged at the lower end of the connecting pipe 2. The side surface of the connecting pipe 2 is fixedly connected with a support connection column 4. The connecting pipe 2 and the raw material tank 3 are in a threaded connection. The opening at the upper end of the support connection column 4 is communicated with the connecting pipe 2. The opening on the surface of the positioning ring 5 is penetrated by the raw material tank 3. When using this device, first fill the raw material through the raw material tank 3, and then fix the raw material tank 3 at the lower end of the connecting pipe 2, so that the raw material tank 3 penetrates the opening of the positioning ring 5.

[0031] The side surface of the lower end of the supporting and connecting column 4 is fixedly connected with a positioning ring 5, and the side surface of the supporting and connecting column 4 away from the spray gun body 1 is rotatably connected with a transmission disc 6. The upper end of the supporting and connecting column 4 is provided with a cavity, and the inner wall of the cavity at the upper end of the supporting and connecting column 4 is rotatably connected with an adjusting screw 7. One end of the adjusting screw 7 passes through the side surface of the supporting and connecting column 4, and one end of the adjusting screw 7 is fixedly connected to the rotating shaft of the transmission disc 6. The adjusting screw 7 is threadedly connected with the gas guide piston head 9 and the damping cylinder 8 respectively. The upper end of the connecting gas groove 10 is located on the side of the gas guide piston head 9 facing the damping cylinder 8. The damping cylinder 8 is a rubber column. The adjusting screw 7 is driven to rotate by rotating the transmission disc 6, so that the adjusting screw 7 drives the damping cylinder 8 to slide close to the raw material tank body 3 through the thread, and the damping cylinder 8 made of rubber material presses against the upper end surface of the raw material tank body 3 to increase the friction force, thereby effectively reducing the rotation of the raw material tank body 3.

[0032] An opening is provided at the upper end of the supporting connecting column 4 towards one end of the connecting pipe 2, and a damping cylinder 8 is slidably connected to the inner wall of the opening at the upper end of the supporting connecting column 4, and an air-guiding piston head 9 is fixedly connected to one end of the damping cylinder 8 towards the adjusting screw 7. A connecting air groove 10 is provided inside the supporting connecting column 4, a transmission piston column 11 is communicated with the connecting air groove 10, and a spring is connected between the transmission piston column 11 and the supporting connecting column 4, a friction pressure plate 12 is designed in an arc shape, and a non-slip pad is provided on the surface of the friction pressure plate 12. When the damping cylinder 8 moves close to the raw material tank body 3, the damping cylinder 8 will drive the air-guiding piston head 9 to inflate the connecting air groove 10, so that the connecting air groove 10 guides the air to the transmission piston column 11. After the transmission piston column 11 is pushed by the air, it drives the friction pressure plate 12 to press against the outer surface of the raw material tank body 3, thereby further improving the friction force on the raw material tank body 3 through the non-slip pad of the friction pressure plate 12, and preventing the raw material tank body 3 from rotating and thus preventing loosening.

[0033] The lower end side surface of the supporting connecting column 4 is provided with an opening, and the inner wall of the opening at the lower end of the supporting connecting column 4 is slidably connected with a transmission piston column 11, one end of the outer side of the transmission piston column 11 is fixedly connected with a friction pressure plate 12, and the upper surface of the friction pressure plate 12 is connected to one end of an air guide hose 13, and two anti-skid suction cups 14 are embedded on the side surface of the friction pressure plate 12, the upper end of the air guide hose 13 is connected to the cavity at the upper end of the supporting connecting column 4, and the upper end of the air guide hose 13 is located at the end of the air guide piston head 9 facing the transmission disc 6, and the anti-skid suction cup 14 is connected to the air guide hose 13. When the damping cylinder 8 drives the air guide piston head 9 to slide away from the air guide hose 13, the anti-skid suction cup 14 is evacuated through the air guide hose 13, so that the anti-skid suction cup 14 forms a negative pressure and then adsorbs the surface of the raw material tank body 3, which is convenient for increasing the stability of the raw material tank body 3 and improving the practicability of the device.

[0034] Working principle: When using this electric spray gun, first, the raw material tank body 3 is installed at the lower end of the connecting pipe 2. By rotating the driving disc 6, the adjusting lead screw 7 is driven to rotate, so that the adjusting lead screw 7 drives the damping cylinder 8 to slide. The damping cylinder 8 presses the threaded surface of the raw material tank body 3. At the same time, the damping cylinder 8 drives the air guiding piston head 9 to slide, so that the air guiding piston head 9 pushes a part of the air into the connecting air groove 10, and the air drives the driving piston column 11 and the friction pressing plate 12 to move to press and fix the outer surface of the raw material tank body 3. By the movement of the air guiding piston head 9 away from the air guiding hose 13, the air guiding hose 13 pumps air out of the anti-slip suction cup 14. After the anti-slip suction cup 14 is in negative pressure, it adsorbs the raw material tank body 3 to improve stability, increasing the overall practicality.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
