Description

A photoelectric switch smoke alarm

technical field

The utility model relates to an alarm, in particular to a photoelectric switch smoke alarm, which belongs to the technical field of building electrical appliances.

Background technique

Photoelectric switch (photoelectric sensor) is the abbreviation of photoelectric proximity switch. It uses the occlusion or reflection of the light beam by the detected object, and the circuit is gated by the synchronous loop to detect the presence or absence of the object. Objects are not limited to metals, all objects that can reflect light can be detected. The photoelectric switch converts the input current into a light signal on the transmitter and emits it, and the receiver detects the target object according to the intensity or presence of the received light. The common photoelectric switch smoke alarm in the security system is often used in the industry to count the number of movements of the mechanical arm.

At present, photoelectric switch smoke alarms are widely used in the field of fire alarms, but they have the following disadvantages in actual use: 1. There are only detection devices, and the detection devices directly report to the control center. 2. Dust will accumulate around the photoelectric switch. If it is not cleaned in time, it will reflect the light speed emitted by the photoelectric switch, resulting in false alarms.

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and provide a photoelectric switch smoke alarm.

The utility model aims to solve the problem that the existing photoelectric switch smoke alarm does not have a buzzer device and cannot timely remind people near the fire and that the light beam of the photoelectric switch is reflected by dust to cause a false alarm.

For realizing the purpose of the utility model, the technical scheme that the utility model adopts is:

A photoelectric switch smoke alarm, comprising a mounting frame, an upper case, a middle case, a lower case and a main body, the main body is composed of an upper case, a middle case and a lower case, and the upper case is arranged on Above the main body, the middle case is arranged in the middle of the main body, the lower case is arranged under the main body, and the installation frame is arranged above the upper case. , a buzzer is set in the lower shell; a controller is also set in the middle of the middle shell, a power supply line is set between the battery and the controller, a control line is set between the controller and the photoelectric switch, the controller and the buzzer Two power supply lines are arranged between the ringers.

A charging circuit is arranged on the storage battery.

Reinforcing ribs are provided on the outer side of the lower casing.

An insect-proof net is also arranged on the periphery of the lower casing.

The outer periphery of the middle housing is also provided with dust-proof glass.

The utility model has the advantages that: by installing a buzzer on the alarm, an alarm sound can be sent out when a fire is detected, and the nearby personnel can be alarmed in time. Installing dust-proof glass around the photoelectric switch can effectively prevent dust from gathering around the photoelectric switch, and avoid false alarms caused by dust reflection. Therefore, the utility model has the advantages of long service life, high safety and good work efficiency, and has broad market prospects.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in the figure, the utility model photoelectric switch smoke alarm includes a mounting frame 3, an upper casing 4, a middle casing 14, a lower casing 15 and a main body 16, and the main body 16 is composed of the upper casing 4, the middle casing 14 and the lower case 15 are composed of three parts, the upper case 4 is arranged above the main body 16, the middle case 14 is arranged in the middle of the main body 16, the lower case 15 is arranged under the main body 16, and the mounting frame 3 is arranged above the upper case 4 Used to fix the main body 16 on the wall, the upper housing 4 is provided with a battery 5 to supply power to each component, the middle housing 14 is provided with a photoelectric switch 6 on both sides, and the lower housing 15 is provided with a buzzer 9. A controller 11 is also provided in the middle of the middle housing 14 to control the operation of various components. A power supply line-2 is provided between the battery 5 and the controller 11 to supply power for it. The connection between the controller 11 and the photoelectric switch 6 A control line 12 is arranged between them, and a power supply line 10 is arranged between the controller 11 and the buzzer 9 .

The battery 5 is provided with a charging circuit 1 for charging it; the outer side of the lower casing 15 is provided with a reinforcing rib 7; the periphery of the lower casing 15 is also provided with an insect-proof net 8 to prevent mosquitoes from entering the interior of the main body 16 to destroy the instrument; the periphery of the middle casing 14 is also provided with Dust-proof glass 13 is arranged so that dust can not gather on photoelectric switch 6.

When the smog of the light beam detection that photoelectric switch 6 sends, can pass information feedback to controller 11 by control circuit 12, controller 11 utilizes power supply circuit 2 10 to open buzzer 9 and give an alarm, prompting nearby personnel to evacuate.
