Description

Structure improvement of spray gun

This model is to provide a structural improvement of a spray gun, especially a structural improvement of a spray gun with more diversified usability.

Press, the so-called spray gun is to spray paint through the nozzle to achieve the effect of coloring or painting. The fields that can be used are quite diverse, such as color painting, nail beauty, model coloring, and artwork manufacturing.

General spray guns will have nozzles that can spray paint, and will be equipped with air jet channels to assist in spraying the paint, and the holes used to control the nozzle flow are mostly controlled by an integral needle seat to selectively shield the discharge The size of the hole controls the flow of paint.

However, the conventional needle holders are directly connected to the adjusted parts, so if they need to be replaced, the entire group needs to be replaced, and different types of replacement actions cannot be performed according to the needs of the user. And it will be more troublesome in manufacturing. In addition to manufacturing the front needle body, it is also necessary to manufacture a related structure connecting the rear seat body.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the applicants of this new model and related manufacturers engaged in this industry urgently want to study and improve.

Therefore, in view of the above-mentioned deficiencies, the applicant of this new model has collected relevant information, evaluated and considered by multiple parties, and based on the accumulated years of experience in this industry, through continuous trials and modifications, the design of this kind of use effect is more diversified. The new type patent for the improvement of the spray gun structure.

The main purpose of the present invention is to achieve the effect that it can be replaced and manufactured more conveniently according to the needs of the user through the separate connecting piece and the output control piece.

In order to achieve the above-mentioned purpose, the main structure of the present invention includes: a spray gun body, a spray gun The main discharge port on the spray gun body, a kit set in the spray gun body and located on one side of the main discharge port, a kit discharge hole set on the kit and located on one side of the main discharge port, a A discharging amount control member movably arranged in the kit and located at one side of the discharging hole of the kit, a connecting member movably arranged on the kit and pressing the discharging amount control member, and a connecting member arranged in the kit and located at both ends respectively The top pressure kit and the elastic element of the discharge amount control member, an inner discharge hole arranged on the connecting piece, and an external control piece arranged on the spray gun main body and connected with the connecting piece.

With the above structure, when the user wants to spray the material, the paint tank can be installed on the external control part, so that the paint can flow into the communicating part. Then the pigment will flow into the kit through the inner discharge hole, and then flow out through the main discharge port for the user to use. And because there is a discharging amount control member on the discharging hole of the kit, the hole size of the discharging hole of the kit can be changed, thereby changing the flow rate of the pigment.

The output amount control member will press the output amount control member against the connecting member through the elastic force given by the elastic element, and the user can drive the connecting member through the external control member, thereby pressing the output amount control member to Change the size of the discharge hole that covers the kit to achieve the effect of changing the flow rate.

In addition, users can change the discharge volume control part according to their needs to change the discharge volume status, and since the discharge volume control part and the connecting part with a simpler type can be manufactured separately, the manufacturing will be easier and more convenient. Replace according to demand.

With the above-mentioned technology, it is possible to break through the more troublesome problems in the replacement and manufacture of conventional spray guns, and achieve the practical advancement of the above-mentioned advantages.

Through the above description, the structure of this technology can be understood, and according to the corresponding cooperation of this structure, the advantages of more diversified usability and more convenient manufacturing can be achieved. The detailed explanation will be explained in the following.

Please also refer to the first to sixth diagrams, which are the preferred embodiment of the new model. From the body diagram to the flow diagram, when the above-mentioned components are assembled, it can be clearly seen from the figure that when the user wants to use, the paint tank 7 can be installed on the external control member 6 through the tank connection part 61, and that’s it. The paint inside the paint tank 7 is allowed to flow into the communicating member 4. The paint will flow into the kit 2 through the inner discharge hole 41, but the discharge amount control member 3 will cover the kit discharge hole 21 to prevent the paint from flowing out. When the user wants to use it, the outside can be turned The control part 6 changes the position of the connecting part 4, and because the elastic element 5 will press the clamping part 31 of the output control part 3, it will push the output control part 3 so that the output control part 3 will not Then cover the outlet hole 21 of the kit, and can achieve the effect of changing the size of the opening that shields the outlet hole 21 of the kit. At the same time, it has the effect of changing the pigment flow rate, so that the pigment can flow from the outlet hole 21 of the kit to the main outlet. The position of the material port 11.

The user can connect the blowing element 12 to an external air supply source, and use the blowing control element 13 to control the flow of the gas blown by the blowing element 12 to blow the paint at the discharge hole 21 of the ejection kit to make The paint is sprayed from the main discharge port 11 to give the user the action of spraying.

And because the output amount control member 3 and the connecting member 4 are separately arranged, the output amount control member 3 and the connecting member 4 can be manufactured separately, so there is no need to manufacture an integrated output amount. The control member 3 and the connecting member 4 can simplify the overall manufacturing process and meet the needs of users in terms of manufacturing. For example, a more slender output control member 3 can be manufactured, so that the sprayed paint can be more detailed. And because it will be easier to manufacture, it is possible to manufacture various sizes of output control parts 3 for users to choose, and the user only needs to replace the output control parts 3 to meet various types of Demand, to achieve the advantage of increasing the diversity of use.
