Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a smoke detection device for detecting smoke filled in a room by, for example, smoking smoke.

[0002]

[Background of the invention]

 The air in the room where a large number of staff members are working is often dirty before they notice it, and the smoke is particularly dirty. In addition, ventilation is rarely done in winter because of heating. Therefore, in order to deal with such a situation, there is a demand for a device that detects the state of dirt in the air, issues an alarm, and promotes ventilation.

[0003]

[Disclosure of device]

 An object of the present invention is to provide a smoke sensing device that senses smoke filled in a room, for example, by smoking. An object of the present invention is to construct a mounting base portion having a latching mechanism and a latching mechanism that latches to the mounting base portion, and stand upright with respect to the mounting base portion. A case body having an opening through which smoke can enter the side wall, a smoke sensor that detects smoke that has entered the case body, and an alarm means that emits a bird's sound by the smoke detection signal output from the smoke sensor. When the smoke sensor is in an operation stop state, an operation stop notification means by sound and a lighting of a lamp, a battery for a power source of the smoke sensor, the alarm means and the notification means, and a battery storage part formed in the case body It is achieved by a smoke sensing device.

The smoke sensing device has a structure that can be easily attached to, for example, the ceiling. Further, when it is attached to the ceiling, for example, smoke can effectively enter the case body. It is also a soft warning because the warning sound is a bird's cry, and it is useful for mentally smoking quitting effect, that is, since the tranquilizing effect is great, the smoking quitting effect of cigarettes is great. Also, even if the smoke sensor that should be activated due to a human error has been stopped, it can be alerted by the sound of the alarm and the lamp, which is a notification means, to call attention, thus ensuring safety. Is also excellent.

【Example】

 1 to 3 show an embodiment of a smoke sensing device according to the present invention. FIG. 1 is a block diagram of the smoke sensing device, FIG. 2 is an overall perspective view, and FIG. 3 is a partial perspective view. .. In each figure, A is a smoke detector, 1 is a case body made of synthetic resin, 1a is an upper case of the case body 1, 1b is a lower case of the case body 1, and 1c is a lid of a battery chamber for storing the battery E. is there. Reference numeral 2 denotes a base portion, and a claw 2a is formed on the base portion 2. When the lower case 1b is arranged on the base portion 2, the claw 2a is engaged with the recess 1d of the lower case 1b. The lower case 1b is fixed to the base portion 2. Further, a concavo-convex mechanism is formed in the abutting portion between the upper case 1a and the lower case 1b, and the upper case 1a and the lower case 1b are abutted (vertical abutment in FIG. 2) so that they are integrated. Is configured. The lid 1c and the upper case 1a are configured such that the guide groove and the latching convex portion are configured to be opened and closed by a sliding operation in the left-right direction in FIG. 2, and the lid 1c can be opened and closed by a sliding operation. The base portion 2 is configured to be fixed to a wall or a ceiling by an adhesive means or a screw.

Reference numeral 3 denotes a sensor control device. The sensor control device 3 sends a signal detected by a smoke sensor (for example, a photoelectric sensor) 3a on the printed circuit board P arranged in the case body 1 and a smoke sensor 3a. The smoke sensor is composed of a control IC chip 3b that judges and outputs a control signal. Smoke that has entered the case body 1 through a slit 1e formed in the side wall of the lower case 1b of the case body 1 is a smoke sensor. When detected by 3a, a signal to that effect is output from the control IC chip 3b.

Reference numeral 4 denotes an alarm device. The alarm device 4 outputs a song of a bird in response to an output signal from the control IC chip 3b, and a control IC chip 4a for amplifying and outputting the song of a bird and a bird's song. It is composed of a speaker 4b which outputs a cry. S is a switch connected between the sensor control device 3 and the alarm device 4, L is a light emitting element connected to the switch S, and the light emitting element L is lit when the switch S and the smoke sensor 3a are inactive. In addition, a warning sound is output.

Reference numeral 5 denotes an external control jack, and the external control jack 5 is configured to output a bird squeal by a signal input from the outside. For example, when a door opening / closing signal is input via the external control jack 5, a bird's call is broadcast according to the opening / closing of the entrance, and it can also be used as an intercom. F is an air freshener set in the space between the lower case 1b and the base 2, and 6 is a battery socket to which a battery is connected.

In the smoke sensing device configured as described above, the battery E is set, and the fragrance F is sandwiched between the base portion 2 and the lower case 1b which are attached to a predetermined position such as a ceiling or a wall, When the case main body 1 is fixed and the switch S is turned on and kept in the operating state, the smoke of the cigarette filled in the room is detected by the smoke sensor 3a, and the detection signal is input to the control IC chip 3b, and the alarm is issued. A speaker crowing is output from the speaker 4b via the control IC chip 4a of the device 4, and the light emitting element L is lit for several seconds.

[0010] And, the alarm sound is a soft sound by the sound of a bird, and furthermore, the fragrance of phytoncide reminiscent of the scent of forest drifts from the fragrance F set together with it, so it is also possible to use it physically. The atmosphere becomes relaxed, and the smoking effect of cigarettes also increases. In addition, for example, the structure is such that it can be easily attached to the ceiling or the like, and in that case, smoke is configured to enter through the slit 1d of the case body 1 and be reliably detected by the smoke sensor 3a.

Further, even when the smoke sensor 3a which should be kept in an operating state due to some human error is in a stopped state, a notification is given by a sound and a light emitting element, which is a notification means, and attention is required. Can be evoked. That is, the operation of stopping the output from the speaker 4b is performed by turning off the switch S. In this case, if the switch S that should be returned to the operating state by the careless mistake is in the stopped state, For example, the configuration is alerted by a beeping sound and the light-emitting element L lights up at intervals of 30 seconds, so that the user is alerted, and thus is highly safe.

【effect】

 A mounting base part having a locking mechanism according to the present invention and a locked mechanism for locking the mounting base part are configured, and smoke is generated on a side wall part standing upright with respect to the mounting base part. A case body having an intrudable opening, a smoke sensor that detects smoke that has entered the case body, an alarm means that emits a bird's cry by a smoke detection signal output from the smoke sensor, and the smoke sensor. When it is in the operation stopped state, it is provided with means for notifying the operation stop by voice and lighting of a lamp, a battery for the power supply of the smoke sensor, the alarm means and the notification means, and a battery storage part formed in the case body. Therefore, the structure is such that it can be easily attached to, for example, the ceiling, and when it is attached to the ceiling, for example, smoke can be effectively introduced into the case body. The alarm sound is the sound of birds Since it is a soft alarm, it is useful not only psychologically but also for the smoking cessation effect of cigarettes.Also, when a smoke sensor that should be in operation has been stopped due to a human error, a notification means is provided. It is also highly safe as it can be alerted by a certain voice and lighting of a lamp to call attention.
