Technical Field
[0001] This utility model relates to the field of airbrush technology, specifically to an airbrush with a leak-proof mechanism. Background Technology
[0002] An airbrush is a tool that resembles an oversized fountain pen, equipped with a container that can hold up to one ounce of liquid paint and a thin tube connecting compressed air and carbonized gas. It can create uniform tones and color gradations, and is a more sophisticated version of the airbrush. An airbrush is a precision instrument capable of producing extremely fine lines and soft gradients. Initially used by photographers and painters for retouching, its potential was quickly recognized, leading to its widespread application and development. The artistic expressiveness of the airbrush is lifelike, its depiction of objects is exquisite and unique, with delicate and natural tonal gradations and soft colors. With the rapid development of science and technology, the paints used in airbrushes have become increasingly diverse and specialized. Now, airbrushes are used in all areas related to beautifying people's lives, with works appearing in art galleries, advertising posters, commercial illustrations, cover design, advertising photography, calendars, paintings, architectural paintings, mixed media painting, makeup, and temporary tattoos.
[0003] Chinese patent publication number "CN215705426U" discloses "a combined simple mini airbrush, including an airbrush body, a first clamping body and a second clamping body, an air pump connecting part on the airbrush body for connecting an air pump, and a retaining part at the end of the airbrush body; the first clamping body and the second clamping body are detachably fixed to the retaining part, and the first mounting part and the second mounting part on the first clamping body and the second clamping body are used to fix airbrush accessories." This patent realizes the combined use of the airbrush, increasing the flexibility of use. However, after the airbrush has been used for a long time, the airbrush control switch will gradually loosen. The loose control switch will cause air leakage in the valve body inside the airbrush, which will lead to liquid leakage. To address this, we propose an airbrush with a leak-proof mechanism. Utility Model Content
[0004] The purpose of this invention is to provide an airbrush with a leak-proof mechanism to solve the problem mentioned in the background art that after prolonged use, the airbrush control switch gradually becomes loose, which causes air leakage in the valve body inside the airbrush, leading to liquid leakage.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an airbrush with a leak-proof mechanism, comprising an airbrush body and a paint bottle, wherein the paint bottle is fixedly connected to the top left side of the airbrush body, and a mounting block is fixedly connected to the bottom left side of the airbrush body.

[0030] This invention provides an airbrush with a leak-proof mechanism, which can prevent leakage, improve the airbrush's performance, and filter the ink to prevent clogging. Please refer to [link / reference]. Figure 1-5 This includes the airbrush body 100 and the paint bottle 200;
[0031] Please see Figure 1-4A mounting block 110 is fixedly connected to the bottom left side of the airbrush body 100. A groove 120 is formed on the front side wall of the mounting block 110. A spring 130 is fixedly connected to the right side wall of the inner cavity of the groove 120. A slider 140 is fixedly connected to the end of the spring 130. A rotating shaft 150 is rotatably connected to the front and rear side walls of the slider 140. A locking ring 160 is rotatably connected to the end of the rotating shaft 150. A control switch 170 is rotatably connected to the top right side of the airbrush body 100. A nozzle 180 is screwed to the left end of the airbrush body 100. An air inlet 190 is fixedly connected to the bottom right side of the airbrush body 100. A handle 191 is fixedly connected to the outer side wall of the air inlet 190. By pulling the locking ring 160 to the right, the locking ring 160 moves the slider 140, which in turn compresses the spring 130 to the right, causing the slider 140 to slide from the left side of the groove 120 to the right side. Then, by rotating the locking ring 160 downward, the locking ring 160 is hooked onto the control switch 170. Subsequently, by slowly releasing the locking ring 160, the spring 130 moves the slider 140 to the left back to its original position. At this point, the locking ring 160 will tightly pull the control switch 170 to the left, thereby achieving the effect of locking the control switch 170 and preventing leakage caused by the control switch 170 becoming loose.
[0032] In summary, this allows the airbrush to avoid leakage and improve its performance.
[0033] Please see Figure 1 , Figure 2 and Figure 5 A paint bottle 200 is fixedly connected to the top left side of the airbrush body 100. A cap 210 is screwed onto the top of the paint bottle 200. A positioning groove 220 is formed on the inner side wall of the paint bottle 200. A first magnet 230 is embedded in the inner side wall of the paint bottle 200 and is located inside the positioning groove 220. A frame 240 is attached to the inner cavity of the paint bottle 200. A positioning block 250 is integrally formed at the bottom of the frame 240. A second magnet 260 is embedded at the bottom of the frame 240 and is located at the positioning block 250. Inside the frame 240, a filter screen 270 is fixedly connected between the inner walls of the frame 240. The filter screen 270 is arc-shaped. By providing the filter screen 270, the pigment is filtered, and impurities are removed to prevent impurities from clogging the nozzle 180. The second magnet 260 is attached to the first magnet 230, making it easy to remove the frame 240 from the pigment bottle 200, which facilitates the subsequent cleaning of the filter screen 270. Finally, the positioning groove 220 and the positioning block 250 facilitate the installation of the filter screen 270.
[0034] In summary, this allows the airbrush to filter the pigment, preventing clogging.
[0035] In practical use, those skilled in the art first connect the air pump to the air inlet 190, then remove the cap 210 and add the required pigment to the pigment bottle 200. After adding the pigment, replace the cap 210. Then, pull the locking ring 160 to the right, causing it to move to the right with the help of the slider 140. This removes the locking ring 160 from the control switch 170. Then, rotate the locking ring 160 upwards to move it away from the control switch 170, thus unlocking it. Next, hold the handle 191 and turn the control switch 170 to spray the pigment from the nozzle 180. During the spraying process, the filter 270 filters the pigment. After use, pull the locking ring 160 to the right again, causing it to move the slider 140. Then, the slider 140 compresses the spring 130 to the right, causing the slider 140 to slide from the left side of the groove 120 to the right side of the groove 120. Then, by rotating the locking ring 160 downward, the locking ring 160 hooks onto the control switch 170. Then, by slowly releasing the locking ring 160, the spring 130 drives the slider 140 to move to the left back to its original position. At this time, the locking ring 160 will tightly pull the control switch 170 to the left, thereby locking the control switch 170. Finally, when cleaning the pigment bottle 200, the frame 240 is removed from the pigment bottle 200 by unscrewing the bottle cap 210, so that the filter screen 270 can be cleaned. After cleaning, the frame 240 is put back into the pigment bottle 200, and the positioning block 250 is aligned with the positioning groove 220, so that the second magnet 260 is attracted to the first magnet 230.
