[0002] Chemical exhaust refers to toxic and harmful gases discharged by chemical plants during chemical production. Many chemical exhausts contain toxic substances. Common toxic chemical exhausts are chemical exhausts containing toxic volatile organic compounds such as benzene, formaldehyde, xylene, and toluene. Waste gas purification mainly refers to the treatment of industrial waste gases such as dust particles, flue gas, odorous gases, and toxic and harmful gases generated in industrial sites. Common waste gas purifications include factory smoke exhaust purification, workshop dust exhaust purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, and chemical waste gas purification. Environmentally friendly purification equipment is required when treating chemical exhaust. The following problems exist in the prior art:

The transmission mechanism includes a servo motor, a transmission rod, a worm, a worm wheel, a rotating rod, a reciprocating threaded groove rod, a limit block, a limit sleeve, a piston rod, a piston plate and a piston cylinder. The upper end surface of the cover plate is fixedly connected to the servo motor through a frame, and the output shaft end of the servo motor is fixedly connected to the transmission rod.
