Abstract
The utility model relates to a fume prevention check valve for a fume exhauster, which is buckled into a cavity structure by a shell and a pinch plate, wherein the upper part of the shell and the upper part of the pinch plate are respectively provided with an interface of a variable diameter fume exhausting pipe; the lower part of the shell is provided with a roller, an elastic positioner and a pulley. An O-shaped sealing ring which is slantwise arranged and the slantwise surface of a square slide valve form a sealing connecting pair, wherein the slide valve is inlaid in a cavity of a valve body, both sides of the slide valve are provided with reset tension springs and the bottom of the slide valve is also provided with a pull rope which is connected between the bottom of the shell and a damping pulley. A positioning clamp pin is arranged on the bottom side of the slide valve to form a positioning mechanism with the elastic positioner on the lower part of the shell. The utility model can be used as a component to be directly arranged between a wind outlet of the fume exhauster and a wind exhausting pipe and can be matched with the fume exhausters with different caliber through the interface of a variable diameter fume exhausting pipe for use, and thus, the usual problem of variable diameter assembly is relieved. The utility model has the advantages that a valve cover can be vertically moved up and down, the opening and the closing of a cover plate are flexible, the installation and the disassembly are convenient and the work effect of the check valve is ensured.
Description
Technical field:
The utility model is the improvement to the anti-down cigarette device of existing kitchen ventilator, discloses a kind of range hood and has returned only valve with anti-oil smoke, belongs to the kitchen fitting technical field.
Background technique:
The device of falling the cigarette that prevents of existing range hood is to be fixed on the kitchen ventilator, be that two semi-circular cover plate structures directly are buckled on the airduct mouth, row of wind by range hood blows it open, the air channel is opened, discharge fume, when air draft stops, by falling from the gravity cover plate, the air channel closed prevent that external wind-fall from irritating and pollute the kitchen, in actual use, because the surface of airduct and cover plate often is stained with greasy dirt, often cover plate is bonded on the airduct mouth tightly, the row of wind of range hood can't be blown cover plate at all and be opened, and causes oil smoke not discharge well, has influenced the normal use of range hood.Because this plate is to be embedded in airduct inside, the keying state of cover plate can't be observed from the outside in addition, the working condition of cover plate can not be handled timely.
Summary of the invention:
The utility model discloses a kind of range hood and returns only valve with anti-oil smoke, and the cover plate that solves the existing anti-down cigarette device of range hood can not normally open and close and can't observe the problem of its working state.
The purpose of this utility model is achieved in that by housing and buckle and closes button and become cavity structure, the top of housing and the top of buckle are respectively equipped with reducing smoke-ejecting pipe interface, it is characterized in that: the interior inclined-plane of housing is provided with the annular groove that the O RunddichtringO is installed, lower part of frame is equipped with running roller, elastic positioner and pulley, the tilting O RunddichtringO and the inclined-plane of square guiding valve constitute the pair that is tightly connected, guiding valve is embedded in the cavity of valve body, the both sides of guiding valve are provided with reset tension spring, the other end of reset tension spring is fixed on the housing, the bottom of guiding valve also is provided with between the damper pulley that stay cord is connected housing bottom, and positioning clamping pin is located at the base of guiding valve and the elastic positioner of lower housing portion constitutes positioning means.
Good effect of the present utility model is: valve is single mechanism arrangement owing to only return, can be used as parts is directly installed between smoke extractor exhaust outlet and the exhaust duct, can be used with the lampblack exhauster of different bores by reducing smoke-ejecting pipe interface, remove common reducing assembly problem from; Valve gap vertically moves up and down, and cover plate opening and closing is flexible, and easy installation and removal has guaranteed the work effect of check valve.
Description of drawings:
Fig. 1 is the utility model structure principle chart.
Fig. 2 is the utility model sectional drawing.
Embodiment:
According to shown in Figure 1, close button and become cavity structure by housing 12 and buckle 1, the top of the top of housing 12 and buckle 1 is respectively equipped with reducing smoke-ejecting pipe interface 10,22, diameter is respectively 150,160, three kinds of sizes of 170mm, the interior inclined-plane of housing 12 is provided with the annular groove that the O RunddichtringO is installed, running roller 7, elastic positioner 9 and pulley 4,5 are equipped with in the bottom of housing 12, and tilting O RunddichtringO 16 constitutes the pair that is tightly connected with the inclined-plane of square guiding valve 11, guarantees that flue gas does not leak; Guiding valve 11 is embedded in the cavity of valve body 12, can move up and down, the both sides of guiding valve 11 are provided with reset tension spring 14, the fixing screw 15 that passes through of the other end of reset tension spring 14 is on housing 12, the bottom of guiding valve 11 also is provided with stay cord 3, handle 2 is connected between the damper pulley 4,5 of housing 12 bottoms, and sealing gasket 6 is sleeved on and prevents on the stay cord 3 that flue gas from leaking; Also be provided with two rubber damping pieces 13 at the top of housing 12, positioning clamping pin 21 is located at the base of guiding valve 11 and elastic positioner 9, running roller 7, the straight pin 8 of housing 12 bottoms constitutes positioning means.
When needs were discharged fume, pulling stay cord 3 affected guiding valve 11 to move down into the bottom of housing 12, and by positioning work piece 21 that guiding valve 11 is fixing, smokejack is all opened, and realizes the smoke evacuation function.
Smoke evacuation spurs stay cord 3 after finishing once more, makes location card 9 leave the bayonet lock of guiding valve 11, and guiding valve 11 upwards resets under the effect of Returnning spring 14, smokejack is blocked close, and prevents that oil smoke from flowing backwards.
