Connecting device for range hood smoke outlet

Abstract

The invention discloses a connecting device for a range hood smoke outlet. The connecting device comprises a corrugated hose. Annular casing pipes are arranged at the two ends of the corrugated hose.A first hinge base and a second hinge base are formed on the opposite inner walls of each casing pipe, wherein an inclined first clamping plate is hinged to one end of the first hinge base, the lowerend of the first clamping plate is close to the inner wall of the casing pipe, and the upper end of the first clamping plate is far away from the inner wall of the casing pipe; an arc first protrusionis formed at the lower portion of the side wall, away from the casing pipe, of the first clamping plate, and the lower end of the side wall, facing the casing pipe, of the first clamping plate is fixedly connected with a piston rod of a first air cylinder; the first air cylinder is hinged to the lower end of the first hinge base; and an inclined second clamping plate is hinged to one end of the second hinge base, an arc second protrusion is formed at the upper portion of the side wall, deviating from the casing pipe, of the second clamping plate, the lower end of the side wall, facing the casing pipe, of the second clamping plate is fixedly connected with a piston rod of a second air cylinder, and the second air cylinder is hinged to the lower end of the second hinge base. The connectingdevice is simple in installation, and smoke outlet and check valve connection is convenient.

Description

Technical field: [0001] The invention relates to the technical field of household appliances, in particular to a connecting device for a smoke exhaust port of a range hood. Background technique: [0002] The range hood is a kitchen appliance that purifies the kitchen environment. The range hood is installed above the kitchen stove, which can quickly remove the waste from the stove and the harmful oil fume generated during the cooking process to reduce pollution, purify the air, and have the safety protection effect of anti-virus and explosion-proof. Existing range hoods generally exhaust smoke from the top, and the exhaust port of the range hood is connected to the flue check valve through a smoke exhaust pipe. However, because the diameter of the exhaust pipe is not universal, it is connected to the exhaust port on the range hood or There will be more or less gaps between the inlets of the check valve, so it is usually necessary to wrap tape on the outer wall of the smoke outle...

Problems solved by technology

Existing range hoods generally exhaust smoke from the top, and the smoke exhaust port of the range hood is connected to the flue check valve through the smoke exhaust pipe. There will be more or less gaps between the inlets of the check valve, so it is usually necessary to wrap tape on the outer wall of the exhaust port of the range hood or the inlet of the check valve for gasket, and then use the clamp to fix the exhaust pipe. more troublesome
