Description

Technical Field

[0001] The utility model relates to the technical field of filtering structures, in particular to a smoke purification and processing device for a smoke exhaust pipe. Background Art

[0002] In the kitchen area, in order to prevent unfiltered oil smoke from being directly discharged to the outside and polluting the atmospheric environment, a filtering structure is needed to capture and adsorb harmful substances in the oil smoke.

[0003] The filtering structure in the existing technology usually quickly inhales the oil fume gas in the kitchen through the range hood. It will first pass through the filter to block and absorb large particulate matter in the oil fume. The filtered smoke is discharged to the outside through the exhaust pipe, thus achieving the filtration of the smoke.

[0004] However, the above-mentioned filtering structure still has some problems. In actual application, particulate impurities will continue to accumulate on the No. 2 filter, gradually blocking the pores of the filter, causing the channel for the oil smoke to narrow, thereby greatly reducing the filtering efficiency. The oil smoke cannot be filtered in a timely and effective manner, thereby polluting the environment and affecting the surrounding air quality. Therefore, in response to the above problems, a smoke purification and treatment device for an exhaust pipe is proposed. Utility Model Content

[0024] The cam 8 is made of nylon and the elastic coefficient of the spring 4 is relatively large. When working, in actual application, particulate impurities will continue to accumulate on the second filter 6, which will gradually block the pores of the filter, causing the channel for the oil smoke to narrow, thereby greatly reducing the filtration efficiency. The oil smoke cannot be filtered in time and effectively, which will pollute the environment and affect the surrounding air quality. As the smoke continues to flow and enters the installation cavity 2, the fan blades 9 drive the rotating shaft 7 to rotate under the impetus of the smoke, and the cam 8 rotates accordingly. When the cam 8 contacts the second filter 6, it impacts the second filter 6. Due to the elasticity of the spring 4, the second filter 6 is compressed. The second filter screen 6 will vibrate after being impacted. The periodic impact vibration can effectively shake off the particulate impurities intercepted on the second filter screen 6, reduce the deposition of impurities, and avoid filter clogging. The gas can be installed in the cavity 2 as it has the function of a discharge port. The deposited impurities can be discharged through the discharge port. The nylon cam 8 is relatively light in weight, which can make the airflow drive the cam 8 to move. At the same time, the spring 4 with a large elastic coefficient can ensure that sufficient vibration effect is generated under the impact of the cam 8, so that the airflow of the flue gas can more effectively drive the cam 8 to vibrate the second filter screen 6.
