Description

Technical Field

[0001] This utility model relates to the field of smoke detector debugging technology, and in particular to a smoke detector debugging device. Background Technology

[0002] Smoke detectors are actually another name for smoke detectors or smoke alarms. Smoke detectors prevent fires by monitoring the concentration of smoke. They use ionization smoke sensors, which are technologically advanced, stable, and reliable sensors that are widely used in various fire alarm systems and have a performance far superior to gas-sensitive resistor-type fire alarms.

[0003] Existing smoke sensors are overly sensitive when detecting smoke, leading to false alarms. They may trigger alarms even when the air contains smoke from indoor smoking rather than combustion. Since the concentration of smoke from smoking is low and dissipates easily, the constant alarms disrupt the normal lives of people indoors. There is a lack of adjustable smoke sensors that can be adjusted to accommodate the amount of smoke entering the room, so that they only trigger an alarm when there is a high concentration of smoke during a fire. Utility Model Content

[0004] The purpose of this utility model is to solve the problems raised by the prior art by proposing a smoke detector debugging device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A smoke detector debugging device includes a plastic housing, a plastic base threadedly connected to the surface of the plastic housing, an arc-shaped hole on the surface of the plastic housing, an adjusting ring plate rotatably connected to the inner wall of the plastic housing, a protruding post fixedly connected to the surface of the adjusting ring plate, a mounting plate fixedly connected to the inner wall of the plastic housing, a plurality of fixing plates fixedly connected to the upper surface of the mounting plate, and a debugging positioning mechanism on the surface of the adjusting ring plate.

[0007] Preferably, the debugging and positioning mechanism includes multiple air inlets formed on the surface of the adjusting ring plate, a moving plate is fixedly connected to the inner wall of the adjusting ring plate, and an arc plate is fixedly connected to the side of the fixed plate near the adjusting ring plate, with the surface of the arc plate fitting against the inner wall of the adjusting ring plate.

[0008] Furthermore, a sensor is fixedly connected to the upper surface of the mounting plate, a control motherboard is fixedly connected to the lower surface of the mounting plate, and a power supply line is fixedly connected to the lower surface of the control motherboard.

[0009] Preferably, a breathable protective net is fixedly connected to the inner wall of the plastic shell, the breathable protective net is sleeved on the outer surface of the adjusting ring plate, and the protruding post is installed inside the arc-shaped hole.

[0010] Furthermore, the inner wall of the arc-shaped hole is provided with multiple V-shaped grooves, and the inner wall of the protruding post is fixedly connected with a V-shaped plastic clamping plate. The V-shaped plastic clamping plate is tough and is used to engage and position with the V-shaped grooves.

[0011] Preferably, the surface of the plastic shell has multiple through holes, a flashing alarm is fixedly connected to the surface of the plastic shell, and an adhesive sticker is adhered to the surface of the plastic base.

[0012] The beneficial effects of this utility model are as follows:

[0013] The V-shaped plastic clamp plate engages with the V-shaped groove for positioning, maintaining stable positioning after the adjustment ring plate rotates. The rotation of the adjustment ring plate changes the position of multiple moving plates. The arc plate blocks the spatial position of the air inlet, controlling the flow of air into the adjustment ring plate. After the moving plate moves closer to the fixed plate, the distance between the moving plate and the fixed plate is reduced, further controlling the amount of air entering the sensor for detection, thereby reducing the sensitivity of the sensor.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-5 A smoke detector debugging device includes a plastic shell 1, a plastic base 2 threadedly connected to the surface of the plastic shell 1, an arc-shaped hole 5 on the surface of the plastic shell 1, an adjusting ring plate 13 rotatably connected to the inner wall of the plastic shell 1, a protruding post 6 fixedly connected to the surface of the adjusting ring plate 13, a mounting plate 14 fixedly connected to the inner wall of the plastic shell 1, a plurality of fixing plates 12 fixedly connected to the upper surface of the mounting plate 14, and a debugging positioning mechanism on the surface of the adjusting ring plate 13.

[0022] By setting the arc-shaped hole 5, the movement of the protruding column 6 is spatially avoided. By setting the adjustment ring plate 13, the space formed between the moving plate 11 and the fixed plate 12 is adjusted, thereby adjusting the amount of smoke sensed by the sensor 7. By setting the mounting plate 14, the sensor 7 and the control main board 10 are installed and fixed.

[0023] In this utility model, reference Figure 3 and Figure 5 The adjustment and positioning mechanism includes multiple air inlets 15 on the surface of the adjustment ring plate 13, a moving plate 11 is fixedly connected to the inner wall of the adjustment ring plate 13, and an arc plate 16 is fixedly connected to the side of the fixed plate 12 near the adjustment ring plate 13. The surface of the arc plate 16 is in contact with the inner wall of the adjustment ring plate 13.

[0024] By setting the air inlet 15, air can be introduced into the inside of the adjusting ring plate 13. By setting the arc plate 16, when the adjusting ring plate 13 rotates, the space of the air inlet 15 is blocked by one side of the arc plate 16, thereby controlling the amount of air entering the air inlet 15.

[0025] In this utility model, reference Figure 2 and Figure 3 A sensor 7 is fixedly connected to the upper surface of the mounting plate 14, a control motherboard 10 is fixedly connected to the lower surface of the mounting plate 14, and a power supply line 9 is fixedly connected to the lower surface of the control motherboard 10.

[0026] Sensor 7 is used to sense the concentration of smoke and dust in the air, and power supply line 9 is used to connect and supply power to the control board 10.

[0027] In this utility model, reference Figure 2 The inner wall of the plastic shell 1 is fixedly connected with a breathable protective net 8, which is sleeved on the outer surface of the adjusting ring plate 13, and the protruding post 6 is installed inside the arc-shaped hole 5.

[0028] By setting up a breathable protective net 8, mosquitoes from the outside are prevented from entering the adjusting ring plate 13. By setting up a protruding post 6, the rotation angle of the adjusting ring plate 13 can be adjusted.

[0029] In this utility model, reference Figure 4 The inner wall of the arc-shaped hole 5 is provided with multiple V-shaped grooves 17, and the inner wall of the protruding post 6 is fixedly connected with a V-shaped plastic clamping plate 18. The V-shaped plastic clamping plate 18 is flexible and is used to engage and position with the V-shaped grooves 17.

[0030] By setting a V-shaped plastic clamp 18, the position of the protruding post 6 is positioned after the V-shaped plastic clamp 18 is engaged with the corresponding V-shaped groove 17.

[0031] In this utility model, reference Figure 1 The surface of the plastic shell 1 has multiple through holes 4, and a flashing alarm 3 is fixedly connected to the surface of the plastic shell 1. The surface of the plastic base 2 is covered with adhesive tape 19.

[0032] Ventilation is achieved by setting through hole 4; the plastic base 2 can be fixedly attached to the wall by setting adhesive sticker 19; and an alarm is activated by setting flashing alarm 3.

[0033] Working principle: Before installation, the protruding post 6 can be pushed forcefully. The V-shaped plastic plate 18 is blocked by the inner wall of the V-shaped groove 17, causing the V-shaped plastic plate 18 to bend and deform to avoid the obstruction. When the protruding post 6 stops, the V-shaped plastic plate 18 is locked in the corresponding V-shaped groove 17 for positioning. The movement of the protruding post 6 drives the adjustment ring plate 13 to rotate. The adjustment ring plate 13 drives the position of multiple moving plates 11 to change. At this time, the arc plate 16 blocks the spatial position of the air inlet 15, controlling the air to flow into the adjustment ring plate 13. The moving plates 11 approach the surface of the fixed plate 12, reducing the distance between the moving plates 11 and the fixed plate 12, thereby controlling the amount of air entering the sensor 7 for detection, thus reducing the sensitivity of the sensor 7. When installing the plastic shell 1, peel off the protective film on the surface of the adhesive 19 and stick the adhesive 19 to the wall for fixation. When the gas concentration detected by the sensor 7 reaches a certain level, the flashing alarm 3 will trigger an alarm.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
