Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an ashtray for smoking, and more specifically to an ashtray with a solar cell.

[Conventional technology]

Conventionally, there has been an ashtray that is equipped with a smoke filtering device consisting of a motor, a fan, a filter, etc., and detects cigarettes using an infrared sensor or detects the temperature of the cigarettes to drive the smoke filtering device.

[Problem that the invention attempts to solve]

These ashtrays have a dry battery installed inside, which drives the smoke filtration device, and the battery needs to be replaced when the battery reaches the end of its service life. The problem is that the configuration is complicated and the cost is high.

[Means for solving problems]

``The present invention has been made to solve the above problems. The solar cell includes a secondary battery, a fan that sucks cigarette smoke, a motor that drives the fan using the secondary battery, and a filter that filters the cigarette smoke sucked by the fan. It is protected by a light-transmitting member such as glass, and the surface of the light-transmitting protective member prevents the light received by the solar cell from being blocked by the cigarette when placed on the surface of the light-transmitting protective member. The cigarette placing part is formed in a positional relationship such that the amount of light received by the cigarette is reduced, and the fan is driven by detecting that a cigarette is placed based on a change in the output current of the solar cell. It is said that

[Effect]

In an ashtray with a solar battery having such a configuration, when there is light from the outside, this light enters the solar cell through a transparent protective member, and the solar cell generates an electromotive force. is charged to the secondary battery. Therefore, the power supply for the fan drive motor is ensured even when there is external light or when there is no external light.

The fan automatically rotates when a cigarette is placed on the cigarette tray and sucks up the smoke rising from the cigarette.
This smoke is filtered through a filter and then exhausted to the outside of the solar cell-equipped ashtray. The state in which cigarettes are placed on the cigarette placement section is detected by detecting a change in the starting force of the solar cell, which is also the power source for rotating the motor. That is, the cigarette rest part is formed on a transparent protection member that protects the solar cells, and when a cigarette is placed on the cigarette rest part, the presence of the cigarette prevents external light from reaching the solar cells. This is done by detecting that the incident light is partially blocked, and as a result, the amount of light received by the solar cells decreases, causing a decrease in the generated starting force. This change in the starting force of the solar cell caused by placing the cigarette down is recognized as distinct from the gradual change in external light incident on the solar cell when the cigarette is not placed, and is used to control the rotation of the fan. It is.

In this way, the solar cell-equipped ashtray of the present invention uses solar cells as a direct power source for rotating the fan or as a power source for charging secondary batteries, and also has a function to detect when a cigarette is placed on the solar cell. I am also responsible for this.
