[0002] Paint is a chemical mixture coating that can firmly cover the surface of an object for protection, decoration, marking and other special purposes. It is widely used in various fields. When paint is mixed with bubbles, it will cause poor fluidity, surface defects, unevenness, and rupture during film formation during the construction process. Therefore, it is necessary to use a bubble elimination device for paint production to process the bubbles in the paint, remove the bubbles inside the paint, and improve the quality of the paint.

[0003] After searching, the Chinese patent application number 202223378999.2 discloses a bubble elimination device for paint processing, including a support platform, a mixing box and a mounting pipe, a mixing box is provided on one side of the support platform, a motor is provided on the top of the mixing box, a feed port is provided on one side of the top of the support platform, a sealing structure is provided on the other side of the top of the mixing box, a discharge port is provided on one side of the mixing box, a mixing frame is provided inside the mixing box, and an elimination structure is provided on the top of the support platform, the elimination structure includes a vacuum pump, a noise reduction box and a connecting pipe, and the vacuum pump is provided on the top of the support platform. The utility model is provided with an elimination structure, in order to prevent the formation of bubbles during the processing and stirring of the paint, the air inside the mixing box can be extracted through the coordinated use of the vacuum pump and the connecting pipe, so that no bubbles will appear when the paint is processed and stirred inside the mixing box, thereby eliminating bubbles;

[0004] The above patent still has the following deficiencies: (1) The defect of being easy to cause serious pollution to the surrounding environment. Since paint usually contains volatile chemicals such as benzene and formaldehyde, when the vacuum pump directly extracts the air inside the tank, it is easy to discharge the toxic gases containing benzene and formaldehyde from the tank, which will affect the health of the workers around the device and easily cause discomfort symptoms such as headaches, eye irritation, and cancer;
