Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste disposers, in particular to an exhaust gas treatment device of a kitchen waste disposer. Background Art

[0002] With existing household waste disposers, users place their daily food waste in a waste bin. A mixing blade grinds the waste into smaller pieces. A heating element then heats the waste in the bin to evaporate moisture, reducing the generation of leachate. The treated waste is then easily absorbed by plants and used as organic fertilizer for their cultivation, allowing for a secondary use of the waste. During the drying process, waste disposers generate a large amount of gas, which not only has an odor but may also carry harmful substances such as bacteria. If this gas is discharged directly into the air, it can cause secondary environmental pollution. Consequently, waste disposers that can handle odors are now available on the market.

[0003] For example, Chinese utility model patent CN215032265U discloses a household garbage grinding and disinfecting device, which includes a body, a control module, and a flip cover. The body is provided with a drive mechanism and a trash can. The trash can is provided with a grinding mechanism, which is connected to the grinding mechanism by a transmission mechanism. The flip cover is provided with a removable sealing cover that matches the top of the trash can. A heating plate is also provided at the bottom of the trash can. A distilled water box is also provided on one side of the body. A removable filter element is embedded between the flip cover and the sealing cover. The sealing cover is also provided with an exhaust hole. Steam passes through the exhaust hole, passes through the filter element, and condenses into the distilled water box. The drive mechanism and heating plate are each electrically connected to the control module. This device can dry, deodorize, grind, and disinfect household food waste. However, the filter element of this device generally uses an activated carbon filter element, which needs to be replaced regularly, making it relatively cumbersome to use.

[0004] Therefore, in view of the above-mentioned problem of needing to replace the filter element regularly, the existing technology still needs to be improved and developed. Utility Model Content
