Description

Technical Field

[0001] The utility model relates to the technical field of cooking fume treatment, in particular to a cooking fume treatment device which is convenient for replacing a filter screen. Background Art

[0002] During the cooking process, toxic gases such as carbon monoxide, carbon dioxide, nitrogen oxides and carcinogens are produced; when the cooking oil is heated to about 270 degrees Celsius, oil mist condensates will be produced, which will cause cell chromosome damage and ultimately lead to skin aging and multiple diseases. In addition, restaurant fumes can also cause lung cancer, pneumonia and other respiratory diseases. If the restaurant fumes are not purified or are not thoroughly purified and are discharged outdoors, they will seriously endanger human health and the surrounding environment.

[0003] Most of the existing equipment for filtering restaurant oil fumes only filters through a single purification method, such as only purifying through a filter net, which makes the oil fume purification incomplete.

[0004] For example, a restaurant oil fume purification device disclosed in Chinese patent CN211399923U includes an oil fume collecting device, an oil fume suction device and an oil fume treatment device. The oil fume collecting device is connected to the oil fume treatment device through the oil fume suction device, wherein the filter net in the oil fume collecting device can preliminarily filter the oil fume, and the oil fume treatment device includes a connected oil fume cleaning device and an oil fume filtering device, which can further clean and filter the oil fume respectively. The utility model utilizes a variety of purification methods to perform multiple purifications on the oil fume, so that the purification of restaurant oil fume is more thorough.

[0005] However, the filter in the oil fume purification device is fixed to the inside of the device, so that when the filter is damaged, it cannot be removed for repair and replacement.

[0006] For this reason, we urgently need to provide a kind of catering oil fume treatment equipment that is convenient for replacing the filter. Utility Model Content

After the rectangular frame is fixed to the inner side of the second treatment box, the rubber pad on the outer side of the rectangular frame contacts the inner side of the second treatment box, so that the contact between the rectangular frame and the inner side of the second treatment box can be kept sealed, so that all the waste gas entering the second treatment box is filtered by the degreasing cotton, the dust filter and the activated carbon filter before being discharged.

[0016] In summary, the present application discloses a cooking fume treatment device that is convenient for replacing the filter.

[0017] According to the technical solution, after the fixing ring is removed from the outer side of the threaded rod by rotating it, the handle can be pulled up to pull the connecting plate out of the through groove, and the rectangular frame at the lower end will be pulled out together, so that the oil removal cotton, dust filter and activated carbon filter in the rectangular frame can be repaired and replaced when they are damaged.

[0018] Furthermore, after the insertion rod is pressed into the circular groove, the fixing plate is no longer fixed to the inner side of the air outlet pipe, and the fixing plate can be taken out of the air outlet pipe. At the same time, the motor and the fan blades will be taken out of the air outlet pipe together, so that the motor and the fan blades can be disassembled for cleaning after being used for a long time.
