Description

FIELD OF THE INVENTION The present invention relates to a smoke generating device that uses a smoke generating agent such as an aqueous glycerin solution to generate smoke for use in testing smoke detectors.

Conventionally, fire alarm systems have been installed in buildings such as offices. In the event of a fire, a smoke detector detects the smoke generated by the fire and sends an alarm signal to the receiver to issue a fire alarm. It is made possible to output, extinguish, evacuate, and firefighting activities.

The fire alarm system is regularly inspected after it is installed in the building. Regarding the smoke detector, the smoke detector installed on the ceiling is removed and a sensitivity test device brought in during the inspection is used. A sensitivity test is performed to confirm that a fire is triggered at a specified smoke concentration, and after the sensitivity test is completed, the smoke detector is attached to the ceiling, and then a portable smoke tester is used to trigger the fire. We are conducting an operation test to confirm that Also, during the construction of fire alarm equipment, a portable smoke tester is used to conduct operational tests to confirm that fire alarms are triggered.

Such conventional sensitivity test equipment and smoke test equipment include those that generate test gas (pseudo smoke) containing smoke-like fine particles by spraying (Patent Document 1), and those that electrically There have been proposed a method in which oily smoke is generated by heating with a heater and forcibly raised by an air blower (Patent Document 2), and a method in which incense smoke is used.

However, since the smoke tester using a spray uses Freon gas, it has a large environmental load, and there are problems such as difficulty in obtaining substitutes for Freon and soaring prices in the future. LPG can be used as an alternative gas, but LPG is flammable and cannot be used at low temperatures.

Further, in the oily smoke type smoke tester, there is a problem that it takes a long time from when smoke is emitted until the smoke sensor issues a test alarm due to an increase in smoke density.

Further, in the smoke tester using incense sticks, there is a problem that the scent of the incense sticks is particularly avoided depending on the test place.

In order to solve this problem, the inventors of the present application put a smoke-producing agent such as a glycerin aqueous solution or a glycolethylene aqueous solution harmless to the human body in a container, and heated the smoke-producing agent impregnated in a nonflammable core material with a heater. We have proposed a smoke generating device that generates smoke, and the necessary amount of smoke generating agent can be put in the container for the test, and when the amount of smoke generating agent decreases due to use, it can be replenished, improving work efficiency. It is possible.

However, the fume generator using an aqueous solution of glycerin, glycol ethylene, etc. stored in a container contains water as the main component, so if for some reason bacteria such as mold are mixed in, the container may become damaged over time. We cannot deny the possibility that the mold that has entered will propagate. Although the heating by the heater basically kills the fungi, there is a risk that the fungi may be released into the air along with the smoke.

In order to solve this problem, it is possible to fill the container with a sterilized smoke generator or replace the smoke generator frequently, but it takes time and effort to manage the smoke generator. may diminish the benefits of using

Also, even if a chemical agent having a bactericidal effect is added, there is a risk that the amount of smoke generated will change or the cost will increase due to the change in physical properties.

SUMMARY OF THE INVENTION An object of the present invention is to provide a smoke generating device that can be used while a smoke generating agent using a glycerin aqueous solution or the like is stored in a container without generating mold.

(basic effect)
The present invention is a smoke generating device for generating smoke used for testing smoke detectors, comprising a smoke generating means for generating smoke by heating a smoke generating agent extracted from a container, and irradiating light on the smoke generating agent contained in the container. Since a sterilization means is provided to sterilize by sterilizing, even if mold is contained in the smoke generating agent using glycerin aqueous solution, glycol ethylene aqueous solution, etc. stored in the container, it is sterilized by light irradiation and enters the smoke generating agent. It is possible to make effective use of the merits that mold does not propagate and deteriorate, operation management such as storage and filling of the smoke generating agent is simple and easy, and the container can be continuously used while replenishing the smoke generating agent.

(Effect of ultraviolet light emitting element)
In addition, since the sterilization means is provided with an ultraviolet light emitting element that emits light to irradiate ultraviolet rays as light to be irradiated, for example, by using a semiconductor element such as an ultraviolet LED having an emission peak at 265 nm with high sterilization ability, Even a small container with a diameter and height of several centimeters or less can be sterilized by arranging an ultraviolet light emitting element in a small installation space and irradiating ultraviolet rays to the smoke generating agent stored in the container.

(Effect of light emission control)
In addition, the sterilization means includes a sterilization control unit that drives the ultraviolet light emitting element to emit light for a predetermined time when power is turned on, when smoke is first emitted after power is turned on, or when a predetermined operation for driving light emission is performed. Therefore, the ultraviolet light emitting element is driven to emit light for several seconds when the power is turned on, when the first smoke starts to be generated after the power is turned on, or at any timing. In some cases, sterilization by ultraviolet irradiation can be performed at least once a day.

(Effect of safety measures)
In addition, the smoke generation control unit prohibits the light emission drive of the ultraviolet light emitting element when detecting the exposure of the smoke generation device to the outside or the removal of the container. When it is exposed to the outside, the ultraviolet light emitting element is prohibited from being driven to emit light, so as to reliably prevent ultraviolet rays from entering the human eye and causing inflammation, etc., and the smoke generating device is not exposed to the outside. High safety is ensured by permitting the light emission drive of the ultraviolet light emitting element only in the case.

(Means for preventing dew condensation on light-receiving element)
In addition, the sterilization means has a partition that separates the space to which the ultraviolet light emitting element and the exposure detection element belong from the space to which the smoke generation means belongs. However, since the exposure detection element is made of a material that transmits the wavelength of the light detected by the exposure detection element, the exposure detection element still has the function of detecting light from the outside. By not moving into the space where the detection element belongs, it is possible to prevent the occurrence of problems associated with condensation, etc.

(Effect of sterilizing light-transmitting material container)
In addition, since at least the portion of the container containing the smoke generating agent that is irradiated with the sterilizing light is made of a material that transmits at least the wavelength range of the sterilizing light, for example, the By forming the container from alkali glass, the sterilizing light emitted from the sterilizing means can be irradiated to the smoke generating agent in the container with little loss, thereby enhancing the sterilizing effect.

(Built-in device for smoke generator)
The smoke generator is a sensitivity test device that supplies smoke to the test space in which the smoke detector to be tested is installed to test the sensitivity of the smoke detector, or a smoke detector installed on the ceiling surface.
