[0027] Working principle: When working, start the fan 7, and use the air inlet pipe 8, the treatment box 6, the heat exchange pipe 4, and the exhaust head 3 to absorb the high-temperature exhaust gas generated by the oven 1 during operation. First, the high-temperature exhaust gas passes through the heat exchange pipe 4 and transfers the heat to the water inside the water tank 5 to achieve the water heating operation to avoid the loss of heat energy in the exhaust gas. At this time, the exhaust gas after heat exchange goes into the treatment box 6, and then is filtered by the filter element 11 and discharged through the exhaust pipe 9, thereby preventing harmful substances in the exhaust gas from being discharged into the air to pollute the working environment and affect the health of employees. When the filter element 11 needs to be replaced, just press The pressing block 21 is moved to drive the triangular block 18 to slide along the inclined surface of the inclined block 16, thereby driving the plug post 15 to disengage from the inside of the socket 23 and compressing the spring 17, thereby releasing the restriction on the filter element 11. Then, the handle 13 is used to pull out the filter element 11 along the slide groove 10 to complete the disassembly, and then a new filter element 11 is inserted along the slide groove 10. When the socket 23 at the upper end of the new filter element 11 corresponds to the plug post 15, the pressing block 21 is released. Under the action of the restoring force of the spring 17, the plug post 15 is automatically stuck in the socket 23, completing the limit fixation of the filter element 11, which is simple and convenient.
