Description

Technical Field

[0001] The utility model belongs to the technical field of smoke alarms, in particular to an Internet of Things smoke alarm. Background Art

[0002] Smoke alarm is another name for smoke sensor or smoke alarm. It prevents fire by monitoring the concentration of smoke. The smoke alarm uses an ion smoke sensor inside, which works stably and reliably. It is widely used in various fire alarm systems and its performance is far superior to gas sensitive resistor fire alarms.

[0003] With the advancement of science and technology, the functions of smoke alarms are becoming more and more perfect. For example, the Internet of Things smoke alarm has a personnel monitoring function. When human activities are detected, a smoke alarm is triggered, and the fire alarm information of people will be reported to the cloud platform. When no one is detected, if there is no one within the "detection interval", a smoke alarm is triggered after the detection interval time, and the fire alarm information of no one will be reported to the cloud platform. However, there are still some shortcomings in its actual use. When installing the smoke alarm, the card block on the alarm body is generally aligned with the card slot on the bracket, and then the alarm body is rotated to complete the installation. During installation, the operator generally installs the alarm on the roof from bottom to top, and the card block and the card slot will be blocked by the line of sight of the alarm body, making the alignment operation very inconvenient, and simply relying on the card block and the card slot cannot ensure the firmness of the installation, so this needs to be improved.

[0011] As a preferred embodiment of the utility model, an elliptical block is fixedly sleeved on the left side of the outer surface of the rotating shaft, and the top of the outer surface of the elliptical block is movably connected to the bottom end of the long plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model uses a snap ring, a round hole, a hemispherical block, a round plate and a first spring. When the alarm body and the bracket are connected, the operator inserts the snap ring into the inner surface of the bracket and rotates the alarm body. At this time, the hemispherical block will be squeezed and move with the round plate and compress the first spring. When the snap ring aligns the round hole and the hemispherical block with the rotation of the alarm body, the hemispherical block will be embedded in the round hole under the restoring action of the first spring. In this way, the connection between the alarm body and the bracket can be completed without the operator having to align the block and the slot in advance, thereby improving the convenience and firmness of the installation of the smoke alarm.

[0014] 2. The utility model uses a long board, an extension block, a second spring, a power motor and an elliptical block. When the power motor is started, the rotating shaft will drive the elliptical block to rotate. Since the outer surface of the elliptical block is movably connected to the outer surface of the long board, the elliptical block will generate a thrust on the long board, pushing the long board to move along the inner surface of the fixed column with the extension block and the round rod and compress the second spring. Under the restoring action of the second spring, the long board will be forced to return to its original position, thereby realizing automatic pressing of the button, thereby eliminating the need for the operator to climb to a high place to press the button.

[0024] When the alarm body 1 is rotated, the alarm body 1 will rotate along the inner surface of the bracket 4 with the snap ring 6, so that the circular hole 7 opened inside the snap ring 6 will squeeze the outer surface of the hemispherical block 8, and then the hemispherical block 8 will move toward the outside of the alarm body 1 with the circular plate 9 and compress the first spring 10. When the hemispherical block 8 and the circular hole 7 are separated, the operator can separate the alarm body 1 from the bracket 4. During installation, the operator only needs to insert the snap ring 6 into the bracket 4 and rotate the alarm body 1 so that the hemispherical block 8 and the circular hole 7 are re-engaged to complete the connection between the alarm body 1 and the bracket 4, thereby improving the convenience of installation of the Internet of Things smoke alarm and the firmness and stability after installation.

[0025] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 A button 11 is movably installed on the right side of the middle of the front end of the alarm body 1, and a fixing block 12 located on the right side of the button 11 is fixedly installed on the outer surface of the alarm body 1.

[0026] As a technical optimization solution of the utility model, the existence of the button 11 realizes the self-checking and silencing of the Internet of Things smoke alarm, while the existence of the fixing block 12 plays a supporting role.

[0027] refer to Figure 1 , Figure 2 and Figure 5 The bottom end of the fixed block 12 is movably sleeved with a long plate 13 , and the left end of the long plate 13 is fixedly installed with an extension block 14 located below the button 11 .

[0028] As a technical optimization solution of the utility model, when the long board 13 drives the extension block 14 to move upward along the inner surface of the fixed block 12, the button 11 will be pressed.

[0029] refer to Figure 2 and Figure 5 The inner part of the long plate 13 is movably sleeved with a limit plate 15 , and the limit plate 15 is fixedly sleeved on the inner surface of the left end of the fixed block 12 , and a round rod 16 is fixedly installed on the right side of the top end of the long plate 13 .

[0030] As a technical optimization solution of the present invention, the outer surface of the limiting plate 15 and the inner surface of the long plate 13 are both smooth, ensuring that the long plate 13 will not get stuck when moving along the outer surface of the limiting plate 15 .

[0031] refer to Figure 2 and Figure 5 A fixing column 17 is movably sleeved on the top of the outer surface of the round rod 16, and the top of the fixing column 17 is fixedly connected to the left side of the top inside the fixing block 12. A second spring 18 is fixedly installed on the top of the round rod 16, and the other end of the second spring 18 is fixedly connected to the top inside the fixing column 17.

[0032] As a technical optimization solution of the utility model, due to the restoring effect of the second spring 18, the round rod 16 will return to its original position after moving.

[0033] refer to Figure 2 and Figure 5 A power motor 19 is fixedly installed at the bottom of the right inner wall of the fixed block 12, and a rotating shaft 20 is fixedly sleeved on the other end of the output shaft of the power motor 19.

[0034] As a technical optimization solution of the present invention, when the power motor 19 is started, the rotating shaft 20 will rotate.

[0035] refer to Figure 2 and Figure 5 An elliptical block 21 is fixedly sleeved on the left side of the outer surface of the rotating shaft 20, and the top of the outer surface of the elliptical block 21 is movably connected to the bottom end of the long plate 13.

[0036] As a technical optimization solution of the present invention, when the rotating shaft 20 rotates with the elliptical block 21, the elliptical block 21 will generate a thrust on the long board 13, pushing the long board 13 to move upward.

[0037] The working principle and use process of this utility model:

[0038] When installing the smoke alarm, the operator first installs the bracket 4 on the roof by bolting the mounting hole 5, and then inserts the snap ring 6 into the bracket 4, so that the outer surface of the snap ring 6 squeezes the hemispherical block 8, causing the hemispherical block 8 to move with the circular plate 9 and compress the first spring 10. When the bottom end of the bracket 4 contacts the top of the alarm body 1, the alarm body 1 is rotated to rotate with the snap ring 6 until the circular hole 7 and the hemispherical block 8 are aligned, so that under the restoring action of the first spring 10, the hemispherical block 8 is embedded in the circular hole 7. At this time, stop rotating the alarm body 1 to complete the connection and installation of the alarm body 1 and the bracket 4. The mutual cooperation of various mechanisms eliminates the need for the operator to align the block and the slot in advance, thereby improving the convenience of installing the smoke alarm and the firmness and stability after installation.

[0039] When it is necessary to press the button 11 to perform self-test or silence the smoke alarm, the operator starts the power motor 19, so that the rotating shaft 20 drives the elliptical block 21 to rotate. At this time, the outer surface of the elliptical block 21 will generate a thrust on the outer surface of the long board 13, pushing the long board 13 and the extension block 14 to move upward along the outer surface of the limit plate 15, so that the round rod 16 fixedly connected to the long board 13 moves along the inner surface of the fixed column 17 and compresses the second spring 18, and the movement of the extension block 14 will press the button 11. At the same time, under the recovery action of the second spring 18, when the smoke alarm completes the self-test or silence, the round rod 16 will restore the long board 13 and the extension block 14 to their original position, thereby realizing the automatic pressing of the button 11, so that the operator does not need to climb a high place to press the button 11.
