Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an ashtray used in spaces where ventilation is relatively infrequent, such as offices and conference rooms.

Structure of the Conventional Example and Its Problems As shown in FIG. 1, the conventional ashtray is composed of a tray portion for storing cigarette ashes and water dregs, and a cigarette tray 2 for storing cigarettes. When tobacco C is lit and placed in an ashtray, smoke B rises as shown in Figure 1. This smoke B increases the dust concentration in the living space, and if there are people who do not like smoking in the adjacent position, it becomes secondhand smoke.
Unfavorable for Health Purpose of the Invention The purpose of the present invention is to discharge smoke generated from a cigarette butt to the outside of an ashtray in a purified state.

Structure of the Invention The present invention is to introduce the smoke generated from a placed cigarette into the ashtray, reduce the amount of smoke through a filter, and then release it into the atmosphere. An air introduction path that leads inside, a fan that creates an airflow that attracts smoke, and a cigarette detection unit such as a switch attached to a cigarette holder, etc., and a fan that rotates in order to control ON/OFF of this fan. Dam motor &'
It consists of a power source and a filter that allows smoke-laden air to pass through and removes harmful components in the smoke.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below. Reference numeral 3 denotes an ashtray main body 6 which has a groove-shaped cigarette holder 5 formed on the upper surface of the outer periphery for receiving cigarettes 4. The ashtray main body 6 is located in the cigarette holder 6 and is equipped with a switch such as a micro switch provided inside the ashtray main body 3 to insert the cigarettes 4 into the cigarette holder 5. It is closed when placed, and is opened when no cigarette 4 is placed on the cigarette receiver 6. Reference numeral 7 denotes a power source such as a battery that is provided in and out of the ashtray main body 3, and 8 is a fan motor provided at the center of the inner bottom of the ashtray main body 3, which is rotated by the power source 7 and rotates the fan 9. 1o is a cylindrical air introduction passage 11 that communicates with the suction port side of the fan 9 and protrudes from the center of the inner bottom of the ashtray body 3.
A plurality of inlets are opened on the upper outer circumferential surface of the tobacco holder 5 and are opposed to the cigarette holder 5.

Reference numeral 12 denotes a filter detachably provided to an exhaust port 13 which communicates with the exhaust port side of the fan 9 and opens on the outer surface of the ashtray main body 3, and is used to remove harmful components from smoke-containing air. 1
Reference numeral 4 denotes a smoke hood such as a flat plate that closes the upper end opening of the air introduction path 11 and guides smoke B from the cigarette 4 placed in the cigarette receiver 5 to the inlet 10. In FIG. 3, each switch 6 of the cigarette holder 5 is connected in parallel to the fan motor 8 in series.

In the embodiment described above, when a lit cigarette 4 is placed on the cigarette tray, the weight of the cigarette turns on the switch 6, which connects the power source 7 and fan motor 8.
A current flows through the circuit, and the fan 9 connected to the rotating shaft of the fan motor 8 rotates. By rotating the fan 90 times, air containing smoke is guided through the smoke hood 14 and passed through the intake port 1.
0, the air is introduced into an air introduction path 10, passed through a fan 9, passed through a filter 12 for air purification, and is purified and discharged into the atmosphere from an outlet 13.

In order to efficiently collect smoke, a smoke hood 14 is provided above the air introduction passage 10 in the center of the ashtray, but this is not always necessary. Further, the filter 12 may be placed before or after the fan 90.

The key is to pass the tobacco smoke through a filter and exhaust it. Further, the switch 6 may be replaced with a sensor that detects smoke B, and in short, any sensor that detects the state in which the cigarette 4 is placed and smoked may be used.

Effects of the Invention The ashtray of the present invention has the above-mentioned configuration, and provides the following effects.

■ By purifying smoke from standing cigarettes with a filter, it is possible to reduce the negative impact on neighbors caused by smoke rising from ashtrays and to reduce the amount of indoor dust.

■ Since the air suction device such as a fan is activated when a cigarette is detected automatically, it is easy to use and works reliably.
