Abstract

PURPOSE:To prevent access of a lighted match or burning ash to a filter and to improve safety by providing an aluminum sheet pierced with many narrow holes behind an ash tray and above the filter. CONSTITUTION:A fan 42 fixed to a motor 41 is rotated, when a switch is turned on. The smoke from a cigarette placed on a groove 49 is sucked from a suction port 16, passed through the narrow hole 20 of the aluminum sheet 19, filtered by a filter 25, passed through a wire mesh 51, and discharged from an exhaust port 43 by the fan 42. In this case, since the aluminum sheet 19 pieced with many holes 20 is provided above the filter 25, the flame generated from the burning of a match, paper, etc., in the ash tray is sucked from the suction port 16. However, the heat is absorbed by the aluminum sheet 19, hence the filter 25 is not burned or melted, and safety is surely enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the safety of smoke evacuators for drawing and filtering tobacco smoke.

2. Prior Art In a conventional smoke evacuator, as shown in FIG. 8, the outer periphery 2 of the ashtray portion 1 is smooth, and the smoke sucked in through the suction port 3 is immediately filtered by the filter 4.

Problems to be Solved by the Invention With conventional smoke evacuators, there is no problem when inhaling cigarette smoke, but when placed in an ashtray with a burning flame,
The flame of the pine tree can quickly reach the filter along the side wall of the ashtray, causing it to burn or melt.Also, if you extinguish a cigarette in the inlet, the lit ash can reach the filter. There was a problem with the filter burning or melting. Also, if you forgot the filter and put out a cigarette in the inlet, sparks would blow out from the exhaust outlet.

The present invention solves these conventional problems and provides a smoke evacuator with a highly safe structure.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides an aluminum plate provided with a large number of narrow holes above the filter at the rear of the ashtray.

Function: With the above structure, the heat of the burning pine when the smoke evacuator is in operation is absorbed by the aluminum plate with a large number of holes.

Furthermore, when a cigarette is extinguished through the inlet, the ashes are absorbed by the aluminum plate.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to all the drawings.

1 to 7, 11 is an ashtray set and an ashtray cover 12. Ashtray 13. It consists of a rectifier plate 14 and screws 15 that fasten the ashtray 13 and ashtray cover 12 together. 1
Reference numeral 6 denotes a suction port formed by the gap between the ashtray cover 12 and the ashtray 13, which together with the comb-shaped lip 1, forms a smoke suction part.

Reference numeral 18 is a collar provided on the outer peripheral side wall of the ashtray 13 to lengthen the suction passage. Reference numeral 19 is an aluminum plate provided with a large number of narrow holes 2o, which is supported by a bearing portion 22 provided on the body urchin 21, and is rotatably mounted on a shaft 23. Note that the aluminum plate 19 may have a large hole 24 in the center to ensure a passage cross-sectional area. A filter 25 includes a charged filter 66 and activated carbon 26. 27 is a body lid, which is fitted into the body lid 28. Reference numeral 29 denotes a buckle provided on the body lid, which is engaged with a groove 30 in the body lid. Reference numeral 31 denotes a switch operation plate, which is supported by a shaft portion 32 provided on the body lid 27, urged upward by a spring 33, and held by a hook portion 34. 35 is a spacer and is held by a holding part 36 provided on the body sea urchin so as to be vertically movable. Further, the spacer 36 has a pre-cut removal stop portion 37 at its upper end and a diamond-shaped elastic portion 38 at its lower end.

39 is a switch mounted on the printed circuit board 40. 41 is a motor, 42 is a fan, 43 is an exhaust port, 44 is a leg rubber, and 4S is a dry battery. 4 in Figure 3
6 is an adapter insertion port, FIG. 4 shows the adapter 4 when used at 100V, and 48 is a terminal that fits into the adapter insertion port 46. In addition, 49 is a tobacco holding groove, 5o is a notice for filter replacement, 51 is a wire mesh, and 52 is a cracker.

With the above configuration, when the adapter is plugged into a 100V power source and the terminal 48 is inserted into the adapter socket 46, or when three dry batteries are inserted and the switch operation plate 31 is pressed, the switch is turned on via the spacer 35. The fan 42 attached to the motor 41 rotates, and the smoke from the cigarette placed in the groove 49 is sucked in through the intake port 16 and passed through the narrow hole 2 of the aluminum plate 19.
0, is filtered by a filter 25, passes through a wire mesh 51, and is discharged from an exhaust hole 43 by a fan 42.

In the above embodiment, an aluminum plate is used, but the same effect can be obtained by using copper or other material with high thermal conductivity.

Effects of the Invention As described above, according to the present invention, in a structure in which a suction port is formed in the upper part of the side wall of the ashtray and the filtered air is discharged to the outside of the container by a motor fan, a large number of inlets are provided at the upper part of the filter at the rear of the ashtray. Since the ashtray is equipped with an aluminum plate with narrow holes, flames from burning pine or paper in the ashtray will be sucked in through the suction port, but the aluminum plate absorbs heat, so the filter cannot be burned. It does not burn or melt, and even if the ash is inhaled when the cigarette is extinguished at the suction port, the aluminum plate absorbs heat and does not damage the filter, making it extremely safe. We can provide high quality smoke evacuators.

By forming a brim on the outer periphery of the side wall of the ashtray, the flames and ignited ash that are sucked in are once trapped inside the ashtray cover by the brim, making it more effective.

In addition, in the unlikely event that you forget to use the filter, even if ignited ash is inhaled from the suction port, the heat will be absorbed and filtered by the aluminum plate, and it will also be filtered by the wire mesh, so no sparks will blow out from the exhaust. It is something. In addition, by installing the wire mesh at an angle, the area of the wire mesh can be increased and pressure loss can be reduced.Also, even if the dust that is sucked in without a filter spreads over the entire surface of the wire mesh during operation, it will fall out when the operation is stopped. Since it gathers downward, it is less likely to cause bad suction the next time you drive, and it is easy to see, making it easy to dispose of.
