Description

Smoke exhaust ventilator

Technical Field

The application belongs to the technical field of kitchen electrical equipment, especially, relate to a smoke ventilator.

Background

The smoke exhaust ventilator is a kitchen appliance for purifying the kitchen environment. The range hood is arranged above a kitchen range, can rapidly pump away waste burnt by the range and oil smoke harmful to human bodies generated in the cooking process, and exhaust the oil smoke out of a room, and can condense and collect the oil smoke, thereby reducing pollution and purifying air. The oil fume is collected by an oil box after being condensed.

At present, most oil boxes are connected with shells of cigarette machines through metal clamping pieces or metal insertion and extraction pieces, but certain metal friction exists between the metal clamping pieces or the metal insertion and extraction pieces, and oil stain liquid in the oil boxes is easy to shake if force is not uniform during oil box disassembly, so that oil stain in the oil boxes is easy to leak; with the long-time use of the range hood, grease is easy to adhere to the clamping pieces, so that the resistance between the clamping pieces is increased, and the difficulty in installation and disassembly is increased; also have the mode of being connected through setting up mounting structure and cigarette machine shell in the oil box, however, mounting structure is changeed the pollution that receives fluid and is leaded to becoming invalid in the oil box, makes the oil box be difficult to the installation and dismantles, and mounting structure also can collect the greasy dirt to the oil box and produce adverse effect.

The above description is included in the technical recognition scope of the inventors, and does not necessarily constitute the prior art.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the purpose of this application is to provide a smoke ventilator, the structure of oil box is simpler, and the installation is dismantled swiftly conveniently, and the installation component can not influence the collection of oil box to the greasy dirt moreover, avoids the installation component to be polluted by the greasy dirt in the oil box, promotes the user and uses experience.

In order to achieve the purpose, the application provides a range hood which comprises a range hood shell, an oil box and a mounting assembly; the oil box is arranged at the bottom of the cigarette case shell and is provided with a hanging part; the mounting assembly is arranged at the bottom of the cigarette machine shell and comprises a connecting piece, a resetting piece and a driving piece, and the connecting piece can move to a hanging position where the connecting piece is matched with and hung on the hanging part and a detaching position where the connecting piece is separated from the hanging part so as to detachably mount the oil box at the bottom of the cigarette machine shell; the reset member generates a force to the link member to move toward the hitching position; the driving piece can drive the connecting piece to move from the hanging position to the detaching position.

In one example, the connecting piece is rotatably arranged on the inner wall of the bottom of the shell of the cigarette machine, the driving piece can drive the connecting piece to rotate to the detaching position, and the connecting piece is provided with a hanging matching part through which the connecting piece is hung with the hanging part.
