Abstract

The utility model discloses a paint spraying pot which comprises a pot body and a pot lid fixed on the upper end of the pot body. The pot lid is provided with a convex column protruding outwardly; the upper end of the convex column has an air inlet hole; the interior of the convex column is hollow and a fixed pipe is fixed on the inner wall of the convex column; the fixed pipe is communicated from top to bottom and is communicated with the interior of the pot body; a soft rubber ring is fixed on the upper end of the fixed pipe; and the middle of the soft rubber ring has an air inlet opening. When paint is sprayed, the air inlet opening is opened by the pressure in the pot body, and the air inlet opening is connected with the air inlet hole and the fixed pipe. When paint is not sprayed, the air inlet opening is closed by the elasticity of the soft rubber ring. The soft rubber ring acts as a "pressure balance valve", which can be automatically turned on or off according to the pressure difference between the inside and outside of the spraying pot, so that the pressure inside and outside the paint spraying pot is balanced, and manual operation is not required, thereby saving time and effort and facilitating the use.

Description PAINT SPRAYING POT Technical Field The utility model relates to a paint spraying pot. Background The paint spraying pot is installed on a spraying gun for use, and paint is contained in the paint spraying pot. The pressure balance of the paint spraying pot in the prior art is controlled by manually operating a pressure balance valve on the paint spraying pot. When paint is sprayed, the valve is turned on; air enters a cup; and the paint is sprayed out, causing that time and labor are consumed and the use is inconvenient. Summary In view of the defects in the prior art, the purpose of the utility model is to provide a paint spraying pot. A technical solution of the utility model is as follows: the paint spraying pot comprises a pot body and a pot lid fixed on the upper end of the pot body. The pot lid is provided with a convex column protruding outwardly; the upper end of the convex column has an air inlet hole; the interior of the convex column is hollow and a fixed pipe is fixed on the inner wall of the convex column; the fixed pipe is communicated from top to bottom and is communicated with the interior of the pot body; a soft rubber ring is fixed on the upper end of the fixed pipe; and the middle of the soft rubber ring has an air inlet opening. When paint is sprayed, the air inlet opening is opened by the pressure in the pot body, and the air inlet opening is connected with the air inlet hole and the fixed pipe; when paint is not sprayed, the air inlet opening is closed by the elasticity of the soft rubber ring. Further, the fixed pipe is fixed on the inner wall of the convex column by clamping. Further, the outer edge of the soft rubber ring is clamped between the upper end of the fixed pipe and the inner top wall of the convex column. Further, a blocking column protruding downward is arranged in the middle

Description position of the inner top wall of the convex column, and the blocking column extends into the soft rubber ring and blocks the soft rubber ring. Further, the fixed pipe is integrally formed by an upper pipe and a lower pipe, and the inner diameter of the upper pipe is larger than the inner diameter of the lower pipe. The paint spraying pot provided by the utility model has the beneficial effects as follows: when the spraying gun works, negative pressure is generated in the paint spraying pot. At this moment, the air inlet opening of the soft rubber ring is automatically opened through the softness of the soft rubber ring to allow the air to quickly enter the pot body, so that the paint can be sprayed successfully. When the spraying gun is not in work, the soft rubber ring closes the air inlet opening through the elasticity. The soft rubber ring acts as a "pressure balance valve", which can be automatically turned on or off according to the pressure difference between the inside and outside of the spraying pot, so that the pressure inside and outside the paint spraying pot is balanced, and manual operation is not required, thereby saving time and effort and facilitating the use.

Fig. 3 is a structural schematic diagram of a soft rubber ring of the utility model. Fig. 4 is a sectional view of a fixed pipe of the utility model. In the figures: 1-pot body; 2-pot lid; 21-convex column; 211-air inlet hole; 212-blocking column; 3-fixed pipe; 31-upper pipe; 32-lower pipe; 4-soft rubber ring; 41-air inlet opening. Detailed Description In order to understand the technical solution of the utility model more intuitively and completely, the non-restrictive features are described as follows in combination with the drawings of the utility model: As shown in Fig. 1 to Fig. 3, a paint spraying pot comprises a pot body 1 and a

Description pot lid 2 fixed on the upper end of the pot body 1. The outer edge of the pot lid 2 is provided with a convex column 21 protruding outwardly; the upper end of the convex column 21 has an air inlet hole 211; the interior of the convex column 21 is hollow and a fixed pipe 3 is fixed on the inner wall of the convex column; the fixed pipe 3 is communicated from top to bottom and is communicated with the interior of the pot body 1; a soft rubber ring 4 is fixed on the upper end of the fixed pipe 3; and the middle of the soft rubber ring 4 has an air inlet opening 41. When paint is sprayed, the air inlet opening 41 is opened by the pressure in the pot body 1, and the air inlet opening 41 is connected with the air inlet hole 211 and the fixed pipe 3. When the paint is not sprayed, the air inlet opening 41 is closed by the elasticity of the soft rubber ring 4. The fixed pipe 3 is fixed on the inner wall of the convex column 21 by clamping. The outer wall of the upper end of the fixed pipe 3 has a bump protruding outwardly, and the inner wall of the convex column 21 has a groove for clamping the bump. The outer edge of the soft rubber ring 4 is clamped between the upper end of the fixed pipe 3 and the inner top wall of the convex column 21. The fixed pipe 3 has the effect of fixing the soft rubber ring 4. A blocking column 212 protruding downward is arranged in the middle position of the inner top wall of the convex column 21, and the blocking column 212 extends into the soft rubber ring 4 and blocks the soft rubber ring 4. When the soft rubber ring 4 is pressed, the blocking column 212 can prevent the soft rubber ring 4 from popping out, thereby preventing the paint from flowing out of the air inlet hole 211. As shown in Fig. 4, the fixed pipe 3 is integrally formed by an upper pipe 31 and a lower pipe 32, and the inner diameter of the upper pipe 31 is larger than the inner diameter of the lower pipe 32. The inner diameter of the upper pipe 31 is larger, so that the inner space of the upper pipe 31 is large and can store more air. The inner diameter of the lower pipe 32 is smaller, so as to prevent the paint from entering the fixed pipe 3 to a certain extent, and restrain the paint from flowing out.

Description When the spraying gun works, negative pressure is generated in the paint spraying pot. At this moment, the air inlet opening 41 of the soft rubber ring 4 is automatically opened through the softness of the soft rubber ring 4 to allow the air to quickly enter the pot body 1, so that the paint can be sprayed successfully. When the spraying gun is not in work, the soft rubber ring 4 closes the air inlet opening 41 through the elasticity. The soft rubber ring 4 acts as a "pressure balance valve", which can be automatically turned on or off according to the pressure difference between the inside and outside of the spraying pot, so that the pressure inside and outside the paint spraying pot is balanced. Of course, the above only describes the preferred embodiments of the utility model, and does not limit the scope of the patent of the utility model. All simple modifications and equivalent structural changes made by using the description and schematic content of the utility model shall be included in the protection scope of the patent of the utility model in the same way.
