Abstract
Description
Technical Field
[0001] This utility model relates to the field of spray gun technology, specifically to a feeding device for easy operation on a spray gun. Background Technology
[0002] A pneumatic spray gun is a spraying device that uses the rapid release of compressed air as power. Compressed air is supplied into the gun body through the air inlet pipe. When the high-pressure compressed air is ejected from the air cap at the front of the nozzle, a negative pressure zone lower than atmospheric pressure is created in front of the paint nozzle. This pressure difference at the nozzle draws the paint out of the paint tank and, under the action of the high-speed jet force of the compressed air, atomizes it into particles and sprays it onto the surface of the object to be coated.
[0003] Paint cans are commonly used and are directly attached to spray guns. While they are convenient to use, the paint can cap must be unscrewed and the paint poured in each time paint is needed, making the operation extremely inconvenient. Furthermore, if not careful, the paint can easily tilt and spill out when the operating angle is large, causing further inconvenience. Therefore, it is essential to improve upon the aforementioned defects in the existing structural design. Summary of the Invention

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a feeding device for easy operation on a spray gun, comprising a spray gun and a paint container connected to the spray gun; the paint container includes a container body and a lid, the container body is connected to the spray gun, and the lid is connected to the mouth of the container body; the lid is recessed into the container body to form a feeding port, through which paint is added to the container body; a positioning connection structure is provided between the lid and the mouth of the container body, and the lid and the container body are fixedly connected and disassembled through the positioning connection structure.
[0006] In the aforementioned feeding device for easy operation on a spray gun, the lid is concave in a cone shape to form the feeding port, and the lid is designed with a feeding hole that communicates with the feeding port.
[0007] In the above-mentioned feeding device for easy operation on a spray gun, the characteristic is that: a feeding hole extension is provided at the feeding hole of the pot lid.
[0008] In the aforementioned feeding device for easy operation on a spray gun, the conical surface of the feeding port forms an angle α with the inner wall of the pot, where the angle α is greater than 30 degrees and less than 90 degrees.
[0009] In the aforementioned feeding device for easy operation on a spray gun, an included angle β is formed between the extension of the feeding hole and the conical surface of the feeding port, where β is greater than 90 degrees and less than 180 degrees.
[0010] In the aforementioned feeding device for easy operation on a spray gun, the positioning connection structure consists of an annular groove and an annular positioning platform that fit together on the lid and the mouth of the pot.
[0011] In the aforementioned feeding device for easy operation on a spray gun, a sealing gasket is provided between the lid and the mouth of the pot body.
[0012] In the aforementioned feeding device for easy operation on a spray gun, the lid has a positioning connecting ring, an annular groove is provided in the positioning connecting ring, and the positioning connecting ring of the lid and the mouth of the pot body are respectively provided with corresponding positioning grooves and positioning bosses.
[0013] In the aforementioned feeding device for easy operation on a spray gun, a transition arc is provided at the junction of the feeding hole and the feeding port.
