A smoke exhaust pipe for connecting the exhaust port of a range hood

Abstract

The invention discloses a smoke discharge tube for connecting with a smoke vent of a range hood. The smoke discharge tube comprises a corrugated flexible pipe; ring-shaped sleeves are arranged at thetwo ends of the corrugated flexible pipe; a plurality of groups of clamping pieces are arranged on the inner walls of the sleeves; the clamping pieces comprise hinge seats fixed to the inner walls ofthe sleeves, clamping blocks hinged to one ends of the hinge seats, racks connected with the clamping blocks, air cylinders, and pin shafts matched with the racks; piston rods of the air cylinders areconnected with the racks; hinge grooves penetrating through the two side walls of the hinge seats are formed in one ends of the hinge seats; the clamping blocks are round and the middle parts of theclamping blocks are hinged to the hinge grooves; tapered bulges are formed on the clamping blocks; gear rings engaged to the racks are formed at the side edges, on one sides of the bulges, of the clamping blocks; locating holes fitting with the pin shafts are formed in one ends of the racks; and the pin shafts are inserted into the sleeves. The smoke discharge tube is simple to mount and is conveniently connected with the smoke vent and a check valve.

Description

Technical field: [0001] The invention relates to the technical field of household appliances, in particular to a smoke exhaust pipe used for connecting 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 on the top of the kitchen stove, which can quickly take away the waste burned by the stove and the oil fume harmful to the human body produced during the cooking process, so as to reduce pollution, purify the air, and have the safety guarantee function of anti-virus and explosion-proof. Existing range hoods generally exhaust smoke from the top, and the smoke outlet of the range hood is connected to the flue check valve through the smoke exhaust pipe. Since the diameter of the smoke exhaust pipe is not universal, it is not compatible with the smoke exhaust port on the range hood or There will be more or less gaps between the inlets of the check valve, so ...

AI Technical Summary

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
