Anti-smoke ball valve and anti-smoke range hood

Abstract

The invention provides a smoke smell prevention ball valve and a smoke smell prevention range hood, and relates to the field of multi-storey residential public flue matched devices and house decoration. The smoke smell prevention ball valve comprises a housing, an inner-through ball, a valve intake port and a valve exhaust port; an exhaust duct which is communicated with the valve intake port and the valve exhaust port is arranged in the inner-through ball; the valve intake port is located at the front end of the housing and is communicated with an exhaust hose of the range hood; the valve exhaust port is located at the rear end of the housing and is communicated with a public flue; the housing covers the inner-through ball which is provided with a rotating shaft; the inner-through ball is in rotating connection with the housing through the rotating shaft; the top of the axis of the housing is provided with a ball valve body which is opened and closed by 90 degrees for limiting; a gap is formed between the housing and the inner-through ball. The smoke smell prevention ball valve and the smoke smell prevention range hood have the beneficial effects that the smoke smell from the public flue is blocked, the problem of oil accumulation at a smoke vent is effectively solved, and a room environment is effectively protected.

Description

technical field [0001] The invention relates to the field of supporting devices for public flues of multi-storey houses and house decoration, in particular to a smoke-odor preventing ball valve and a smoke-odor preventing range hood. Background technique [0002] At present, the oil fume exhaust of multi-storey and high-rise residential kitchens on the market is configured in the way of centralized oil fume exhaust through public flues. This method of public centralized oil fume exhaust solves the problem of environmental pollution caused by individual households' scattered oil fume exhaust. At the same time, the air pressure in the public flue increases, and the oil fume is poured into the homes of users who do not use the range hood under the action of the air pressure, polluting the indoor air. And because the range hood extracts a large amount of oil fumes, it will accumulate a large amount of oil dirt in the oil fume exhaust pipes, common door sealing panels and smoke ...

Problems solved by technology

This method of public centralized oil fume exhaust solves the problem of environmental pollution caused by individual households' scattered oil fume exhaust. When used at the same time, the air pressure in the public flue increases, and the oil fume is poured into the homes of users who do not use the range hood under the action of the air pressure, polluting the indoor air

And because the range hood extracts a large amount of oil fumes, it will accumulate a large amount of oil dirt in the oil fume exhaust pipes, common door sealing panels and smoke outlets of the public flue, resulting in the lax closing of the sealing door panels, causing the oil fumes to pour into the room and bring troubles to the majority of users. come confused
