Description

Self-spring type safety ashtray

The utility model belongs to human security fireproofing technique field, exactly, is that a kind of preventing dropped cause fire outside ashtray owing to the cigarette of burning, and places the eject Safety cigaret pot of stub for the smoker.

Now, the fire that causes owing to smoking happens occasionally, wherein many is because the cigarette of lighting is positioned over nothing leaves when not having other people, cigarette then and there again and burning away to certain position from back smoker on the common ashtray of bouncing function, its out-shift of gravity center and the cigarette of firing is dropped on inflammable articles such as desktop or other furniture, cause and caught fire, even cause fire, bring serious harm for human lives and properties.Do not have from the shortcoming that plays fire-proof function for overcoming common ashtray, aim to provide a kind of eject Safety cigaret pot, cigarette playing device is housed on ashtray, when the cigarette of burning placed thereon burns the temperature-sensitive position of cigarette playing device, cigarette playing device springs into cigarette in the cylinder body, it is outer and burn on firely to avoid cigarette to fall cylinder, drops to the purpose that causes fire on outer other the inflammable object of ashtray thereby reach the stub that prevents because of burning.So propose the utility model.

The utility model is achieved in that the cigarette playing device that adopts ABS engineering plastics injection mo(u)lding bullet cigarette frame and thermal sensitive piece to form combines with the ceramic cylinder body two big parts of making.Cigarette playing device is made up of fixing bullet cigarette frame, movable bullet cigarette frame, thermal sensitive piece, fixes to play cigarette frame and movable bullet cigarette frame ABS engineering plastics injection moulding typing, chrome-faced, smooth, heat-resisting.Fixing to play the cigarette frame be front end and toply do not seal, the narrow meshed hollow cuboid in both sides.Movable play the cigarette frame has two small columns for the front end both sides rectangular of arc.Movable two small columns that play on the cigarette frame are set in the aperture of fixing bullet cigarette frame both sides, but axial rotation 90 degree.

Thermal sensitive piece in the cigarette playing device is the heat-sensitive duplex metal material, be characterized in the coefficient of expansion difference of each layer of bimetal leaf, deformation generation elastic force takes place in the back so be heated, hook-type temperature-sensitive length of a film end is fixed in fixing the bullet in the groove of cigarette frame bottom surface, above the short end is that the little one side of the coefficient of expansion contacts with small embossment stress contact below the activity bullet cigarette frame, when the thermal sensitive piece critical surface is heated, hook thermal sensitive piece dilatancy, produce elastic force promotion activity bullet cigarette frame and make axial rotation, upwards rotate more than 75 degree by horizontal direction, stub is sprung in the cylinder body automatically, can play the fire safety effect.Shape of block is external diameter 132mm, the cylinder of high 27mm, that inside has is concentric with external diameter, internal diameter is 82mm, the cylinder shape groove of dark 22mm, open the cuboid groove of two long 25mm, wide 16mm, dark 10.5mm in the circular rings upper surface symmetry of cylinder body, inlay cigarette playing device in the groove and be combined into eject Safety cigaret pot finished product.

Embodiment of the present utility model is described below in conjunction with the accompanying drawings:

Fig. 1 is a structure chart, and wherein 1 is thermal sensitive piece, and 2 are the fixing cigarette frame that plays, and 3 is louvre, and 4 is the movable cigarette frame that plays, and 5 is stress contact, and 6 is cylinder body.

Thermal sensitive piece adopts thick 0.1mm bimetallic thermo-sensitive material, is cut into the rectangle of long 35mm, wide 6.7mm, and through the hook-type of punch forming for long end: 25mm, short end 10mm, the fixing bullet in the groove of cigarette frame bottom surface is fixed in its long end punching press.Thermal sensitive piece is the thermo-sensitive material that the different metal material of the two-layer coefficient of expansion is combined into, and the outside of hook-type thermal sensitive piece is the little one deck of the coefficient of expansion, and another side is the big one deck of the coefficient of expansion.Through test, 107 ℃ of heating temperatures, thermal sensitive piece is short under the condition in 15 seconds holds upwards distortion to reach 75 degree, i.e. and promotion activity bullet cigarette frame upwards rotates more than 75 degree, and cigarette placed thereon is sprung in the cylinder body automatically.

It is fixing temperature-sensitive film trap that the fixing cuboid that plays cigarette frame 2 for long 25mm, wide 15.5mm, high 11.5mm, end inner face have the groove of wide 6.8mm, dark 0.5mm.The aperture of diameter 4mm is arranged is louvre 3 in 1/3 center behind the bottom surface, and its effect is to make the thermal sensitive piece that is heated dissipate waste heat the movable cigarette frame that plays is resetted as early as possible.Two sides have 2 diameter 2mm apertures and the movable pillar assembling that plays on the cigarette frame 3, but axial rotation 90 degree.

Rectangular of the arc that movable bullet cigarette frame 4 is long 32mm, wide 12mm, the small embossment of the high 1mm in front end bottom surface, diameter 0.5mm is a stress contact 5, colliding above holding with thermal sensitive piece is short contacts.The fixing cigarette frame that plays plays the cigarette frame by the injection mo(u)lding of ABS engineering plastics with activity, and the chrome-faced layer thickness is 0.1mm, and is smooth, can be heat-resisting more than 362 ℃.During cigarette combustion after tested hot face temperature be 217 ℃.

Fig. 2 is a top view, and cylinder body 6 is a ceramic cylinder shape, adopts fired the forming of machined steel mould system embryo.The cuboid groove of two long 25mm of its annular upper surface band, wide 16mm, dark 10.5mm.Cylinder body external diameter 132mm, cylinder diameter 82mm, dark 22mm, outer high 27mm, annulus is wide is 25mm.1/2 part behind fixing bullet cigarette frame 2 two sides, preceding 1/2 part in bottom surface, employing epoxy resin and polyamide are adhered to the interior corresponding site of two grooves on the cylinder body.The groove corresponding site leaves the usefulness of the gap of 0.5mm for heat radiation.

Fire prevention eject ashtray has attractive in appearance, generous profile, and cylinder body also can adopt materials such as marble, glass, cloisonne enamel to make, and forms the ornament with different-style characteristics, integrates and decorates practical and fire safety effect.

The eject Safety cigaret pot is the practical fire safety articles for use in places such as family, office, meeting room, hotel, restaurant, dining room, and social benefit is widely arranged, and uses so can extensively promote.

The utility model is easy to use, and performance is safe and reliable, is to prevent because smoking causes the safety article of fire.
