[0015] 3. Use the filter bracket to provide support for the filter screen. After the exhaust gas in the purification box passes through the filter screen, the dust and large particles in the exhaust gas are intercepted by two groups of filter screens, thereby performing preliminary filtration on the exhaust gas.
