TECHNICAL FIELD

The present invention relates to the technical field of kitchen ventilators, in particular to a portable kitchen ventilator used for a pot body.

BACKGROUND

A kitchen ventilator is a kitchen appliance that purifies the kitchen. It is installed above a kitchen range, and can draw away the waste from the combustion of the range and cooking fume harmful to a human body during cooking, discharge the fume to the outside while condensing and collecting same, reduces pollution, purifies the air, and has safety protection function of gas prevention and explosion prevention.

The kitchen ventilator needs to be cleaned regularly as it collects oil smoke. Generally, oil smoke is a large amount of volatile edible oil pyrolysis products and partial volatile products produced when cooking food at a high temperature above 220° C., mainly volatile oil, organic matter and its heating decomposition or cracking products. Simple cleaning cannot eliminate greasy dirt, and the kitchen ventilator must be cleaned with professional cleaning agent.

At present, a kitchen ventilator is commonly used for collecting and processing oil smoke. For example, patent application No. 199720006349.7 discloses a computer intelligent kitchen ventilator including a body composed of a housing, a fan and a keyboard, characterized in that: a controller is provided on the housing, and the controller is composed of a power supply circuit, a detection circuit, a signal response circuit, a display drive circuit, a controllable circuit and a microcomputer chip which are connected via a wire; the power supply circuit outputs to the detection circuit, the signal response circuit, the display drive circuit and the microcomputer chip respectively; and the microcomputer chip is connected to the detection circuit, the signal response circuit, the display drive circuit, the controllable circuit and the keyboard respectively via the wire. Further, patent application No. 201620382503.4 discloses an embedded folding range hood includes a housing, a fan assembly located in the housing, and a collecting chamber slidingly connected to the housing, wherein the bottom of the housing is provided with an opening, the collecting chamber at least partially disposed in the opening and connected to the housing through the slide rails, the slide rails are at least two groups, and the two sets of slide rails are disposed on different sides of the smoke collecting chamber.

Further, patent application 202110518693.3 discloses a smoke guide pipe and a kitchen ventilator. The smoke guide pipe includes a first pipe and a second pipe, and the first pipe and the second pipe are oppositely connected to form an outer pipe wall surface and an inner smoke guide channel, and the outer pipe wall surface is provided with a first drive transmission mechanism capable of swinging the first pipe relative to the second pipe.
