Background

In order to remove oil fume generated in the cooking process, most of the existing household kitchens are provided with a range hood. As a common household kitchen appliance, a range hood has already entered numerous households, and a flip-top range hood is one of the range hoods. The cover-lifting type range hood comprises a casing with an open front side, a smoke exhaust device arranged in the casing and a smoke baffle plate covering and mounted on the front side of the casing. When the range hood is not used, a user can enable the smoke baffle plate and the machine shell to be in a closed state, a smoke exhaust device in the range hood is protected, and the integrity of the range hood and the appearance of a kitchen is kept. When the range hood needs to be used, a user can turn the smoke baffle upwards to lift the smoke baffle, and the smoke baffle can be used for guiding so as to play a role in concentrating and guiding oil smoke.

The smoke baffle plate in the prior art is mainly connected with the shell through a hinge joint so as to achieve the function of relative overturning. However, since the smoke barrier is generally made of thin metal, the structural strength is not high, and when an assembler locks screws on the smoke barrier to fix the hinge structure, the cover plate is easily depressed due to excessive force; and because the hinge structure only has a small area to pass through the smoke baffle, the hinge fixing effect is not ideal, the structure is not firm, and even the integrity of the smoke baffle is damaged. In order to solve the defects, a connecting device of a smoke baffle plate of a range hood is urgently needed.

The clutch device comprises a clamping point arranged on the pressure plate and a positioning groove arranged on the chassis, and the clamping point is inserted into the positioning groove to play a role in locking the relative position between the chassis and the pressure plate.

The number of the clamping points is at least three, and the clamping points are distributed on the pressure plate in an annular array mode.

The clamping point is in the shape of a right triangle, the inclined plane of the clamping point is a guide inclined plane, and the guide inclined plane is arranged in a rotating direction facing the door opening.

The locating grooves are waist-shaped and penetrate through the chassis, and the locating grooves are distributed in an annular array by taking the center of the chassis as the center of a circle.

The cylinder of rotation axis on be provided with the recess, in the recess was arranged in to the cardboard card on the rotation axis, spring one end support and press on the support, the other end supports and presses on this cardboard.

The utility model has the advantages that: 1. simple structure, the cost of manufacture is low, improves market competition. 2. The operation is quick and convenient, the smoke baffle can be automatically locked after being turned upwards, the opening state of the smoke baffle is kept, and a user can conveniently clean the inside of the range hood. 3. Novel open and locking structure can make the user operation get up and have more scientific and technological sense, promotes the operation impression.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The utility model provides a connecting device of lampblack absorber fender cigarette board which characterized in that: the range hood comprises a rotating shaft 1 fixed on a smoke baffle 2, wherein the rotating shaft 1 is rotatably hinged and installed in a bracket 3 on a range hood body 4; a base plate 6 is arranged on the rotating shaft 1 in a sleeved mode, and the base plate 6 is fixed with the bracket 3; the rotating shaft 1 is also coaxially and fixedly provided with a pressure plate 7, a clutch device 5 is arranged between the pressure plate 7 and the chassis 6, a spring 8 is arranged between the rotating shaft 1 and the bracket 3, and the spring 8 generates thrust to always push the rotating shaft 1 and the pressure plate 7 to move towards the chassis 6.

The clutch device 5 is a clamping point 51 arranged on the pressure plate 7 and a positioning groove 52 arranged on the chassis 6, and the clamping point 51 is inserted into the positioning groove 52 to lock the relative position between the chassis 6 and the pressure plate 7.

The number of the clamping points 51 is at least three, and the clamping points are distributed on the pressing plate 7 in an annular array.

The fastening point 51 is in the shape of a right triangle, the inclined surface of the fastening point is a guide inclined surface 9, and the guide inclined surface 9 is arranged in a rotating direction facing the door opening.

The positioning slots 52 are waist-shaped and penetrate through the chassis 6, and the positioning slots 52 are distributed in an annular array by taking the center of the chassis 6 as a circle center.

The cylinder of rotation axis 1 on be provided with recess 10, in recess 10 was arranged in to cardboard 11 card on the

rotation axis

1, 8 one end of spring support and press on support 3, the other end supports and presses on this cardboard 11.

The working principle is as follows: in the scheme, when a user needs to use or clean the range hood, the smoke baffle is lifted manually, and the rotating shaft fixed on the smoke baffle rotates along with the smoke baffle. After reaching the position needing to be stopped, because the spring is arranged between the rotating shaft and the support, the spring generates thrust to always push the rotating shaft and the pressure plate fixedly installed on the rotating shaft to move towards the direction of the chassis, so that the chassis and the pressure plate are always in close contact. The clamping point on the pressure plate slides into the clamping groove of the chassis along with rotation, so that the smoke baffle plate is fixed. When the user need not use or clean lampblack absorber, only need press the cigarette board to the right side, owing to keep off and be equipped with certain interval between cigarette board and the support for keep off that the cigarette board is whole to be moved to the right side, the stuck point breaks away from the draw-in groove this moment, chassis and pressure disk separation keep off the cigarette board and reset.

Compared with the traditional hinge structure, the novel structure is simpler, the manufacturing cost is low, the operation is rapid and convenient, the convenience of user operation is greatly improved, and the user can clean and maintain more conveniently.

Further, the stuck point is right angled triangle, and its inclined plane is the direction inclined plane, and the direction inclined plane sets up in the face of opening the door soon, after stuck point and draw-in groove contact, has avoided inertia antiport, has guaranteed separation phenomenon can not appear after stuck point and the draw-in groove contact, and firm in connection is stable, and joint strength is effectual for keep off the locking that can be by firmly after the cigarette board is opened.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
