[0033] Example:

[0034] See also Figure 1-2A self-protection component for a wireless smoke alarm includes a base 1 and a hot wax plug 7. The base 1 is provided with a plurality of mounting holes 2, and an alarm body 3 is installed at the bottom end of the base 1. A pair of mutually symmetrical protective shells 4 are slidably connected to the bottom end of the base 1. The pair of protective shells 4 are arranged on both sides of the alarm body 3, and one end of the pair of protective shells 4 is fixedly connected to a rack 5. The pair of racks 5 are centrally symmetrical. A trigger component 6 is arranged at the bottom end of the base 1. The trigger component 6 includes a mounting block 601. A rotating rod 602 is rotatably connected to the mounting block 601. A gear 603 and a knob 604 are fixedly connected at both ends of the rotating rod 602. A pair of racks 5 are meshed with the gear 603.

[0035] Wireless smoke alarm is an important safety device, widely used in homes, offices and public buildings. It can detect fire early and notify people to take appropriate countermeasures by sounding alarms or sending alarm signals. The main body of the alarm is usually made of plastic, and they usually lack protective functions. When a fire occurs, the alarm can only serve as an alarm. If the fire is not stopped in time, the alarm itself is also at risk of damage.

[0036] In this solution, the alarm body 3 is installed at the bottom of the base 1. The user can set the base 1 at the desired location, usually on the ceiling of the room or corridor, and fix the base 1 by screwing through the mounting hole 2. The material of the pair of protective shells 4 can be insulating ceramic fiber. Ceramic fiber has excellent thermal insulation performance and can achieve effective heat isolation. In the event of a fire, the alarm body 3 first detects smoke and sounds an alarm. If the fire is not contained in time, the temperature in the room will rise sharply. At this time, the alarm body 3 made of plastic material is very susceptible to high temperature damage. At this time, through the setting of the trigger component 6, the pair of protective shells 4 can be automatically triggered to approach each other when the temperature is high, so that the alarm body 3 is wrapped in a pair of protective shells 4, and the alarm body 3 is insulated. At this time, the alarm body 3 has already sounded the alarm in time, reminding people to evacuate and put out the fire in time, and the alarm body 3 will not affect the previous alarm notification after being covered. Such a setting can effectively protect the alarm body 3 from fire damage, ensure that it can continue to work reliably, reduce additional economic losses, and more effectively protect the safety of life and property.

[0037] See also Figure 3-4A torsion spring 605 is sleeved on the outer end of the rotating rod 602, and the two ends of the torsion spring 605 are fixedly connected to the gear 603 and the mounting block 601 respectively. A limiting hole 606 is provided on the knob 604, and a limiting groove 607 matching the limiting hole 606 is provided on the end of the mounting block 601 close to the knob 604. The limiting hole 606 and the limiting groove 607 are both matched with the hot wax plug 7. The hot wax plug 7 passes through the limiting hole 606, and one end of the hot wax plug 7 is inserted into the inner cavity of the limiting groove 607.

[0038] When the user installs the base 1 and the alarm body 3, the user can rotate the knob 604, thereby driving the rotating rod 602 to rotate on the mounting block 601, and then driving the gear 603 to rotate. Through the rotation of the gear 603, a pair of racks 5 are prompted to move away from each other, thereby driving a pair of protective shells 4 to move to both sides of the alarm body 3, so that the detection area of ​​the alarm body 3 is exposed to the outside, ensuring its normal operation. While rotating the rotating rod 602, the torsion spring 605 is squeezed. When the limiting hole 606 is aligned with the limiting groove 607, the user can insert a hot wax plug 7 into the limiting hole 606 and the limiting groove 607 respectively, so as to fix the knob 604 and the gear 603. The hot wax plug 7 is a temperature-sensitive element made of special wax material. At room temperature The hot wax plug is in a relatively hard solid state, and when the temperature rises to near the melting point of the hot wax plug (usually between 50-100°C), the wax material will begin to gradually change from a solid to a semi-solid or liquid state. Therefore, when a fire occurs and the fire cannot be contained in time, the hot wax plug 7 will be affected by the sharply increased temperature in the room and will melt quickly. The melted hot wax plug 7 will no longer limit the knob 604, so the mounting block 601 and the gear 603 will reset and rotate under the elastic force of the torsion spring 605, thereby driving a pair of protective shells 4 to slide towards each other at the bottom of the base 1, and wrapping and protecting the alarm body 3. After the fire is over, the user can reopen the pair of protective shells 4 and re-fix them with a new hot wax plug 7, thereby improving the convenience of repeated use.

[0039] A mounting groove 608 is provided on the mounting block 601, and the mounting groove 608 is connected to the limiting groove 607, and a heat conducting wire 609 is provided in the inner cavity of the mounting groove 608, the bottom end of the heat conducting wire 609 extends to the lower side of the mounting block 601, and the top end of the heat conducting wire 609 abuts against the outer end of the hot wax plug 7.

[0040] The material of the thermal wire 609 can be copper with good thermal conductivity. When a fire occurs, the ambient temperature rises rapidly, and the thermal wire 609 can quickly transfer heat to the hot wax plug 7, accelerating the phase change and melting of the hot wax plug 7. Such a setting can greatly improve the response speed of the protective shell 4 and shorten the startup time of the alarm body 3 to be protected, thereby protecting the alarm body 3 more effectively and timely.

[0041] Working principle:

[0042] The user sets the base 1 at the desired position and fixes the base 1 by screwing through the mounting hole 2. During installation, the user turns the knob 604, thereby driving the rotating rod 602 to rotate on the mounting block 601, thereby driving the gear 603 to rotate. Through the rotation of the gear 603, a pair of racks 5 are prompted to move away from each other, thereby driving a pair of protective shells 4 to move to both sides of the alarm body 3, so that the detection area of ​​the alarm body 3 is exposed to the outside, ensuring its normal operation. While rotating the rotating rod 602, the torsion spring 605 is squeezed. When the limiting hole 606 is aligned with the limiting groove 607, the user can insert a hot wax plug 7 into the limiting hole 606 and the limiting groove 607. The positioning hole 606 and the limiting groove 607 are used to fix the knob 604 and the gear 603. When a fire occurs and the fire cannot be contained in time, the hot wax plug 7 will begin to melt due to the rapid increase in temperature in the room. At the same time, the heat conducting wire 609 can quickly transfer heat to the hot wax plug 7, so that the hot wax plug 7 accelerates the phase change and melting. The melted hot wax plug 7 no longer limits the knob 604. Therefore, the mounting block 601 and the gear 603 will reset and rotate under the elastic force of the torsion spring 605, thereby driving a pair of protective shells 4 to slide towards each other at the bottom of the base 1, and wrap the alarm body 3 to achieve heat insulation protection for the alarm body 3.

[0043] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
