Description

Technical Field

[0001] This utility model relates to the field of fire protection detection technology, specifically a remote triggering device for a smoke alarm used in fire protection detection. Background Technology

[0002] Smoke detectors, also known as fire smoke alarms, smoke sensors, or smoke detectors, are powered by a bus. Multiple smoke detectors can be connected to the bus to form an alarm system that is networked and communicates with a fire alarm controller. Smoke detectors undergo trigger testing at the factory to ensure timely activation.

[0003] Existing smoke detectors require staff to ignite a burning material to generate smoke, which is then detected by the detector. Manually igniting a burning material to generate smoke triggers and destroys the detector, leaving combustion residue that requires secondary cleaning and causes dirt and grime at the detection site, hindering its widespread use.

[0004] Therefore, this application proposes a remote triggering device for a smoke alarm used in fire detection to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a remote triggering device for smoke alarms used in fire detection, which has the advantages of strong practicality and good stability, and solves the problems mentioned in the background technology.

[0007] As a preferred embodiment of this utility model, a cover plate is installed on the top of the protective cover, and a visualization plate is installed on the inner wall of the cover plate. The visualization plate is made of transparent tempered glass.

[0008] As a preferred embodiment of this utility model, the outer edge of the pressure plate is provided with a plurality of protrusions arranged in a ring shape.

[0009] As a preferred embodiment of this utility model, the exhaust pipe is connected to the interior of the cavity, a control valve is installed on the outside of the exhaust pipe, and the outlet of the exhaust pipe is close to the outside of the smoke alarm.

[0010] As a preferred embodiment of this utility model, an oiling pipe is installed on the outside of the smoke-making chamber, and a ball valve is rotatably installed on the inner wall of the oiling pipe. The interior of the cavity is connected to the oiling pipe.

[0011] As a preferred embodiment of this utility model, a controller is installed on the outside of the protective cover, and the controller, heating tube and control valve are all electrically connected, and the controller is electrically connected to an external control terminal.

[0012] As a preferred embodiment of this utility model, the cavity is filled with smoke oil, a battery is installed on the inner wall of the protective cover, and the battery, heating tube and control valve are electrically connected.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This is a remote triggering device for a smoke alarm used in fire detection. The smoke alarm allows for remote control of the heating element to heat the smoke oil inside the cavity, which in turn generates smoke. The smoke is then discharged through the exhaust pipe into the interior of the protective cover and can be directly ejected from the outside of the smoke alarm. This device is used to actively trigger the smoke alarm for smoke detection without the need to manually ignite burning materials to generate smoke, making it more environmentally friendly.

[0015] This remote triggering device for fire detection smoke alarms uses a magnetic plate to connect the extension ring to the smoke alarm, preventing easy separation. This facilitates simultaneous placement of the alarms in a single space for testing and allows for batch testing of multiple smoke alarms sequentially. Simultaneously, rotating the protrusion causes the pressure plate and threaded ring to rotate, allowing the threaded ring to be removed from the inner wall of the cavity. This further facilitates the user's cleaning and maintenance of any residual smoke oil inside the cavity after heating. Attached Figure Description

[0022] Please see Figure 1-4 A remote triggering device for a smoke alarm for fire detection includes a protective cover 1. A smoke alarm 4 is installed inside the protective cover 1. A smoke generating chamber 5 is installed on the outer edge of the smoke alarm 4. A cavity 6 is opened inside the smoke generating chamber 5. A heating tube 7 is installed at the bottom of the cavity 6. A threaded ring 9 is threadedly connected to the inner wall of the cavity 6. A pressure plate 10 is installed on the top of the threaded ring 9. An extension ring 12 is installed on the inner wall of the pressure plate 10. Four grooves 13 are opened at the bottom of the extension ring 12. Magnetic plates 14 are installed on the inner walls of the four grooves 13. The bottom of the magnetic plates 14 is magnetically connected to the top of the smoke alarm 4. A smoke exhaust pipe 15 is installed on the inner wall of the pressure plate 10.

[0023] In the above structure, the magnetic plate 14 allows the smoke alarm 4 to be stably installed at the bottom of the extension ring 12, and the smoke generating chamber 5 can be stably installed outside the smoke alarm 4 using magnetic attraction, so that it forms a closed environment installed as a whole inside the protective cover 1.

[0024] In a preferred embodiment, a cover plate 2 is installed on the top of the protective cover 1, and a visualization plate 3 is installed on the inner wall of the cover plate 2. The visualization plate 3 is transparent tempered glass.

[0025] In the above structure, the visualization panel 3 allows the smoke-filled state inside the protective cover 1 to be viewed without opening the cover 2, further improving the visualization effect.

[0026] In a preferred embodiment, the outer edge of the pressure plate 10 is provided with a plurality of protrusions 11 in a ring shape;

[0027] In the above structure, the protrusion 11 makes it easy for the user to rotate the pressure plate 10 to drive the threaded ring 9 to rotate, and further facilitates the threaded ring 9 to be threaded onto the inner wall of the cavity 6, making it easier for the user to apply force with their hand.

[0028] In a preferred embodiment, the exhaust pipe 15 communicates with the interior of the cavity 6, a control valve 16 is installed on the outside of the exhaust pipe 15, and the outlet of the exhaust pipe 15 is close to the outside of the smoke alarm 4.

[0029] In the above structure, the smoke oil inside the cavity 6 is heated by the heating tube 7, which can quickly generate smoke. The smoke can then be discharged into the interior of the protective cover 1 through the exhaust pipe 15 and can be sprayed directly out of the smoke alarm 4 to actively trigger the smoke alarm 4 for smoke detection.

[0030] In a preferred embodiment, an oiling pipe 17 is installed on the outside of the smoke-making chamber 5, and a ball valve 8 is rotatably installed on the inner wall of the oiling pipe 17. The interior of the cavity 6 is connected to the oiling pipe 17.

[0031] In the above structure, the refueling pipe 17 can be used to add vapor oil to the inside of the cavity 6 for refueling treatment. Furthermore, the ball valve 8 can be used to seal the inside of the refueling pipe 17 to ensure that the inside of the cavity 6 is sealed and that the vapor oil inside the cavity 6 will not easily evaporate.

[0032] In a preferred embodiment, a controller 18 is installed on the outside of the protective cover 1. The controller 18, the heating tube 7 and the control valve 16 are all electrically connected. The controller 18 is electrically connected to an external control terminal.

[0033] In the above structure, the smoke alarm 4 enables the heating tube 7 to be remotely controlled to heat the smoke oil inside the cavity 6, which can further generate smoke. At the same time, the control valve 16 can be controlled to adjust its opening to ensure the density of smoke inside the protective cover 1, and to detect the timeliness of the alarm when the smoke alarm 4 is under different smoke density conditions.

[0034] In a preferred embodiment, the cavity 6 is filled with aerosol oil, a battery is installed on the inner wall of the protective cover 1, and the battery, heating tube 7 and control valve 16 are electrically connected.

[0036] Working principle:

[0037] First, the smoke alarm 4 and the smoke generating chamber 5 can be installed inside the protective cover 1. Then, the controller 18 can be used to remotely control the heating tube 7 to heat the smoke oil inside the cavity 6, which can further generate smoke. The smoke can be discharged into the interior of the protective cover 1 through the smoke exhaust pipe 15 and can be sprayed directly out of the outside of the smoke alarm 4 to actively trigger the smoke alarm 4 for smoke detection.

[0038] Then, the state of the smoke inside the protective cover 1 can be viewed using the visualization panel 3 without opening the cover 2. Furthermore, the protrusion 11 can be rotated to drive the pressure plate 10 and the threaded ring 9 to rotate, thereby removing the threaded ring 9 from the inner wall of the cavity 6. This makes it easier for the user to clean and maintain the residual smoke oil inside the cavity 6 after heating. Smoke oil can be added to the inside of the cavity 6 through the refueling pipe 17 for oil replenishment. Furthermore, the ball valve 8 can be used to seal the inside of the refueling pipe 17 to ensure that the inside of the cavity 6 is sealed and that the smoke oil inside the cavity 6 will not easily evaporate. The magnetic force of the magnetic suction plate 14 can connect the extension ring 12 to the smoke alarm 4, preventing easy separation.
