Description

Technical Field

[0001] The utility model relates to the technical field of smoke alarm equipment, in particular to a mounting structure of a smoke alarm. Background Art

[0002] Smoke alarms are safety devices that detect smoke concentrations in the air and sound an alarm to alert people to potential fire hazards. They are widely used in homes, office buildings, factories, hotels, and other places. Their primary purpose is to quickly detect smoke in the early stages of a fire, thereby sounding an early alarm and buying valuable time for evacuation and firefighting.

[0003] Chinese patent publication number CN220252683U discloses a smoke alarm mounting structure, including a smoke alarm, wherein a connecting block is fixedly mounted on the top outer wall of the smoke alarm, a limiting groove is provided inside the top of the connecting block, a mounting device capable of mounting the smoke alarm is provided on the top of the smoke alarm, and an absorption device for absorbing smoke is provided on the bottom outer wall of the smoke alarm.

[0004] Although the existing installation structure of smoke alarms can improve the detection sensitivity of smoke by actively supplying air, its active air supply method may cause a large amount of dust to be deposited in the smoke alarm. After the dust particles enter the smoke sensing chamber of the smoke alarm, they will interfere with the normal operation of the detector, thereby triggering a false alarm. In addition, the accumulation of dust particles inside the detector may block the smoke sensing chamber or the optical path, resulting in the smoke being unable to enter the detector smoothly, thereby reducing the alarm's sensitivity to smoke. Therefore, it is necessary to develop a smoke alarm installation structure with a dust-proof function. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention specification.

[0023] Example:

[0024] like Figure 1-3 As shown, the mounting structure of a smoke alarm described in this embodiment includes a top base 1, the top base 1 is provided with a mounting hole 2, the mounting hole 2 is used to fix the top base 1 and the ceiling; a smoke alarm 10, the smoke alarm 10 is fixedly arranged at the lower part of the top base 1, and the side of the smoke alarm 10 is provided with an air inlet 11; an air collecting pipe 3, the air collecting pipe 3 is arranged at the lower part of the top base 1, and the air collecting pipe 3 is sleeved on the outside of the smoke alarm 10, and the air collecting pipe 3 is composed of a first tube body 31 and a second tube body 32. The first tube body 31 is integrally arranged on the upper part of the second tube body 32. The diameter of the second tube body 32 is larger than that of the first tube body 31. A plurality of air outlets 4 are opened on the side of the first tube body 31. The air inlet 11 is located at the connection between the first tube body 31 and the second tube body 32. When the airflow flows from the second tube body 32 to the first tube body 31, the direction of the airflow blows into the air inlet 11 of the smoke alarm 10, so as to increase the air flow rate of the smoke alarm 10, thereby improving the detection accuracy of the smoke alarm 10. The filter 6 is detachably arranged at the lower part of the air collecting pipe 3. The diameter of the filter 6 is between the diameter of the dust and the diameter of the smoke particles, thereby blocking the dust and allowing the smoke to pass smoothly. By setting the filter 6, the device can actively filter the dust, effectively avoiding the accumulation of dust in the smoke alarm 10, and ensuring the normal operation of the smoke alarm 10. A blower mechanism is arranged at the lower part of the filter 6. The blower mechanism includes a bracket 5 and a fan 7. The fan 7 is arranged at the lower center of the bracket 5. The lower part of the air collecting pipe 3 is provided with a first magnet 8, and the upper part of the bracket 5 is provided with a second magnet 9. The filter 6 is fixed between the air collecting pipe 3 and the bracket 5 by the first magnet 8 and the second magnet 9. The first magnet 8 and the second magnet 9 are both permanent magnets. By setting the first magnet 8 and the second magnet 9 to fix the filter 6, the filter 6 is very convenient to disassemble, which greatly improves the convenience of device maintenance, reduces the maintenance cost of the device, and reduces the workload of the staff.

[0025] How it works

[0026] When installing the smoke alarm 10, first, fix the top base 1 to the ceiling by passing the bolts through the mounting holes 2, then fit the filter 6 under the first magnet 8, and then lift the bracket 5 so that the first magnet 8 and the second magnet 9 attract each other, and fix the filter 6 to complete the installation of the smoke alarm 10.

[0027] When the smoke alarm 10 is working, the fan 7 is started, and the air flow passes through the filter 6 under the action of the fan 7 and enters the second tube body 32. When passing through the filter 6, the dust in the air flow is intercepted by the filter 6, and the smoke passes through the filter 6. The air flow containing the smoke continues to flow upward. When passing through the connection between the first tube body 31 and the second tube body 32, the smoke is guided into the smoke alarm 10, and finally the remaining gas is discharged from the air outlet.

[0028] Utilizing the technical solution described in the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above-mentioned technical effects, all fall within the scope of protection of the present invention.
