Abstract
An air outlet of a down-draft-proof range hood comprises an air outlet body and two semi-anti-return air sheets, wherein the lower surfaces of the semi-anti-return air sheets are provided with annular bulges, and the peripheral surfaces of the annular bulges are provided with clamping grooves; a gap is reserved between the pivoting seat and the bottom plate of the counter bore; the rubber gasket is characterized by also comprising a round gasket made of rubber materials, wherein the round gasket is provided with a pin joint position, and through holes are symmetrically arranged on the round gasket at the two sides of the pin joint position; the circular gasket is attached to the two half anti-wind-back sheets, the annular bulge is matched with the through hole, the circular gasket at the through hole is embedded into the clamping groove of the annular bulge, and the end part of the pivoting position is positioned in a gap between the pivoting seat and the bottom plate of the counter bore; when the sealing device is closed, the lower surface of the radial edge of the circular gasket is attached to the bottom plate of the counter bore. By adopting the structure, when the semi-non-return air piece is closed, the circular gasket is tightly attached to the semi-non-return air piece and the bottom plate of the counter bore; because the circular gasket is made of rubber materials, the circular gasket has good elasticity and can prevent the half-counter-wind sheet from accidentally overturning.
Description
Technical field
The utility model relates to a kind of device used for range hood, especially a kind of air outlet of range hood.

Currently available technology, a kind of air outlet of range hood of down-draught-proof comprises air outlet body and two and half non-return wind sheets, the counterbore that one is positioned at top is had in described air outlet body, the pin joint seat at diameter line two ends is had in counterbore, pin joint seat has two and half axis holes, the semiaxis of half non-return wind sheet and half axis hole of pin joint seat are rotatably assorted.Existing problems are: poorly sealed, still have wind to enter indoor from the external world.
Utility model content
The purpose of this utility model is: the air outlet providing a kind of range hood of down-draught-proof, and it can have the tight feature of sealing.
The utility model is achieved in that a kind of air outlet of range hood of down-draught-proof, comprise air outlet body and two and half non-return wind sheets, the counterbore that one is positioned at top is had in described air outlet body, the pin joint seat at diameter line two ends is had in counterbore, pin joint seat has two and half axis holes, the semiaxis of half non-return wind sheet and half axis hole of pin joint seat are rotatably assorted; Its special character is: the lower surface of described half non-return wind sheet has annular protrusion, and the outer circumferential surface of annular protrusion has draw-in groove;
Gap is had between described pin joint seat and the base plate of counterbore;
Also comprise the circular gasket that an elastomeric material is made, described circular gasket has the pivot joint position being positioned at a diameter line, there is symmetrically arranged through hole the both sides of pivot joint position;
Described circular gasket and two and half non-return wind sheets are fitted, and annular protrusion coordinates with through hole, and the circular gasket at through hole place embeds in the draw-in groove of annular protrusion, in the gap between pin joint seat and the base plate of counterbore, the end of pivot joint position;
When closing, the radial edges lower surface of circular gasket and the base plate of counterbore are fitted.
The air outlet of the range hood of described a kind of down-draught-proof, its special character is: there is axle bed on the string limit of described half non-return wind sheet, and the two ends of axle bed are provided with semiaxis;
The pivot joint position of described circular gasket is the recess of a upper shed;
Described axle bed coordinates with recess.
The air outlet of the range hood of described a kind of down-draught-proof, its special character is: the through hole of described circular gasket is arcuately; Described annular protrusion is a bow-shaped ring.
The air outlet of the range hood of a kind of down-draught-proof of the utility model, owing to adopting such structure, when half non-return wind sheet is closed, the base plate of circular gasket and half non-return wind sheet and counterbore fits tightly; Because circular gasket is made up of elastomeric material, there is favorable elasticity, can also prevent half contrary wind sheet from surprisingly overturning.
