Description

Technical Field

[0001] The utility model relates to a paint spraying device for containing paint for use by a paint spraying gun, in particular to a paint spraying pot body. Background Art

[0002] The paint spray pot is used to hold paint, and is connected to the spray gun through a joint. The existing paint spray pot generally includes an inner pot, an outer pot, and a pot cover. The inner pot is placed in the outer pot, the pot cover tightly covers the outer pot, and the joint is connected to the pot cover. When in use, the paint in the inner pot is drawn out and atomized and sprayed by the external force of the spray gun. As the paint flows out, the amount of paint remaining in the inner pot decreases, the internal air is drawn out, and the paint in the inner pot is not easy to be drawn out, thereby affecting the uniformity and atomization effect of the paint spraying, resulting in an unsightly painted surface. Summary of the invention

[0003] In order to solve the deficiencies in the prior art, the utility model provides a paint spray pot body to solve the problems of smoothness and uniformity when spraying paint.

[0004] The above-mentioned invention object of the utility model is achieved through the following technical solutions:

[0005] The utility model provides a paint spray pot body, comprising:

[0006] The pot body has a connecting boss at the bottom, a connecting through hole is formed in the middle of the connecting boss, and a pot cover connecting part is formed on the upper part of the pot body;

[0007] And a rubber one-way valve, which is connected to the kettle body through an interference fit via a connecting through hole.

[0008] By adopting the above technical scheme, when the paint is contained in the paint spray pot body, the rubber one-way valve is in a closed state, and the rubber one-way valve is tightly connected to the pot body to prevent the paint from flowing out; when in use, the paint spray pot body is connected and fixed with the pot cover and the spray gun, and the paint spray pot body is in an inverted state. At this time, the rubber one-way valve is on top and the pot body is on the bottom. The spray gun is started, part of the air and paint in the pot body are sucked out, the internal air pressure of the paint spray pot body is lower than the external air pressure, the rubber one-way valve is opened, and the external air enters the pot body through the opened rubber one-way valve, and under the external action of the spray gun, the paint in the paint spray pot body is discharged smoothly and evenly.

[0009] Furthermore, the kettle body is a barrel-shaped structure, and the kettle body extends downward in a circumferential direction to form a supporting portion, and a through groove is provided at a position corresponding to the supporting portion and the connecting boss.

[0010] By adopting the above technical solution, when the paint spray pot body is placed, the support part provides support for the pot body, and a space of a certain height is formed at the bottom of the paint spray pot body to accommodate the connecting boss and the rubber one-way valve.

[0011] Furthermore, the connecting boss is cylindrical on the outside, the connecting through hole is coaxially arranged with the connecting boss, the upper end of the connecting through hole is truncated cone-shaped, and the lower end is cylindrical.

[0012] By adopting the above technical solution, the connecting through hole in the middle of the connecting boss forms a structure with a small end and a large end, so that it is more tightly matched with the rubber one-way valve.

[0013] Furthermore, the rubber one-way valve is integrally provided with a sealing rib along its annular direction.

[0014] By adopting the above technical solution, the friction between the rubber one-way valve and the wall surface of the connecting through hole can be increased, and the connection tightness between the rubber one-way valve and the connecting boss can be further increased.

[0015] Furthermore, the sealing ribs are provided in two groups, and the two groups of sealing ribs are arranged in parallel.

[0016] Furthermore, a plugging cap is integrally provided at the end of the rubber one-way valve, and the diameter of the plugging cap is greater than or equal to the diameter of the connecting boss.

[0017] By adopting the above technical solution, the plugging cap can completely cover the connecting boss, making the plugging and unplugging operations easier.

[0018] Furthermore, the outer diameter of the pot cover connecting portion is greater than the maximum outer diameter of the pot body, and a plurality of arc-shaped thread segments are evenly arranged on the outer edge of the pot cover connecting portion.

[0019] By adopting the above technical solution, a flange is formed between the lid connecting part and the pot body, which is convenient for holding and connecting. The arc-shaped thread section is compatible with the structure of the lid, and the lid can be connected in a threaded connection manner.

[0020] Furthermore, a groove is formed at the lower portion of the arc-shaped thread segment.

[0021] By adopting the above technical solution, the groove is matched with the buckle on the pot cover to increase the tightness of the connection between the pot cover and the pot body.

[0022] Furthermore, the rubber one-way valve is a duckbill valve.

[0023] To sum up, the utility model includes at least one of the following beneficial technical effects: the paint spray pot body of the utility model does not use an inner liner, and is directly used in conjunction with the pot lid and the spray gun. Under the action of the spray gun, the pressure inside the pot body is adjusted by opening and closing the rubber one-way valve, and the paint is sprayed evenly and smoothly under the action of the paint's own weight and the suction of the spray gun.
