[0002] Chinese patent number "CN211467431U" discloses a blow molding machine that prevents air dust, including a blow molding machine body, and fixed columns are fixedly installed on the left and right sides of the top of the blow molding machine body. The blow molding machine that prevents air dust, by setting a cleaning ring, when the blow molding machine body is working, the electrostatic generator works to generate a unipolar charge, which is transmitted by the wire to the metal rod to generate regional static electricity. Since the dust itself also carries a charge, static electricity has a strong adsorption effect on the dust. Therefore, when the power of the electrostatic generator is large, it can generate a strong attraction in a large range, adsorbing the dust on the metal rod. At the same time, the water pump and the electric slide rail are started, driving the cleaning ring to move while cleaning the dust on the surface of the metal rod, so that it is wetted and settled in the receiving bucket for centralized treatment. In this way, the dust content in the air in this area will drop sharply, which does not affect the product quality. The overall operation is simple and the effect is good, and the effect of preventing air dust is achieved. However, the device will produce sewage, which is not convenient for collection and treatment, and the installation requires a large space, which affects the use scenario of the device, so improvements are proposed.
