[0003] The existing exhaust purification system has poor purification effect. Generally, the smoke purification system processes the smoke through the filter and activated carbon. Only through the filter and activated carbon can it process some solid particles, etc. The treatment effect is poor, and it is difficult to remove harmful substances in the smoke. Harmful substances will not only pollute the air, but also have an adverse effect on human health. It is also not convenient to clean the filter residue. After the filter filters the particles in the smoke, the particles will be concentrated inside the device and need to be cleaned regularly. When cleaning, the device is generally disassembled and opened, and then the filter residue inside is cleaned with tools, and then it is installed after cleaning. The whole cleaning process is relatively cumbersome, which increases the workload and reduces the cleaning efficiency. In addition, the internal space of the device is small and difficult to operate, which increases the difficulty of cleaning.
