Description

Technical Field

[0001] The invention belongs to the technical field of smoke alarms, and in particular relates to a side-emitting sound smoke alarm. Background Art

[0002] A smoke alarm, also known as a smoke detector or smoke sensor, is a device used to monitor smoke. When the smoke concentration exceeds the set threshold, it will send out an audible and visual alarm signal to remind people that a fire may have occurred so that people can take timely measures to prevent the fire from spreading further and causing greater losses. In order to increase the alarm sound of the smoke alarm and expand the transmission range, some smoke alarms will install the buzzer on the side of the shell.

[0003] The existing side-sounding smoke alarm is basically composed of an infrared light source and a photosensitive element. The infrared light source emits a beam of infrared light. If smoke enters the light-proof and ventilated monitoring box, the infrared light will dissipate heat, thereby weakening the light intensity received by the photosensitive element. After the light is fed back to the circuit board, the resistance increases and exceeds the preset threshold, which will cause the buzzer to work, thereby alerting people to pay attention to safety.

[0004] When smoke is generated, it usually reaches the ceiling and spreads first. When the smoke contacts the smoke alarm, the smoke inlet of the alarm is usually located below, so it takes a certain amount of time for the smoke to enter the interior of the alarm. Therefore, this design limits the monitoring efficiency and response speed of the smoke alarm to a certain extent. In addition, the smoke inlets of existing smoke alarms have certain insect and dust prevention functions, but require regular maintenance. However, the smoke alarm is bolted to each other by multiple shells, which makes it very inconvenient to maintain. Summary of the invention

[0040] It should be particularly noted that the upper shell 16 and the lower monitoring assembly 17 are completely identical, so the objects included in the lower monitoring assembly 17 are also included in the upper shell 16 .

[0041] Reference Figure 3-Figure 7 In a further embodiment, a clamping plate 14 is disposed above the monitoring box 13 , and clamping grooves 12 are provided on both sides of the circuit board 11 and the clamping plate 14 , and the clamping grooves 12 fit the clamping blocks 173 .

[0042] It should be particularly noted that after the monitoring box 13 opened on the circuit board 11 and the clamping plate 14 is aligned with the clamping block 173, the circuit board 11 and the clamping plate 14 are rotated so that the circuit board 11 can be clamped into the interior of the receiving component 18, and the monitoring box 13 can be clamped into the interior of the upper shell 16 and the lower monitoring component 17, so that modular installation and disassembly can be carried out, which is convenient for replacement and maintenance. In addition, during the installation process of the circuit board 11, the external buzzer is also embedded in the interior of the receiving ring shell 181 and connected through lines. The circuit board 11 itself is also connected to the wires in the base 15 through lines, and then connected to the external power supply line.

[0043] Reference Figure 2-Figure 6 In a further embodiment, docking grooves 172 are provided on both sides of the upper shell 16 and the lower shell 171, and T-shaped pieces 174 are slidably connected to the inside of the docking grooves 172. Three return springs 175 are fixedly connected below the T-shaped pieces 174, and the other end of the return spring 175 is fixedly connected to the inner wall of the docking groove 172. The end of the T-shaped piece 174 away from the return spring 175 fits into the inside of the hook 184.

[0044] It should be particularly noted that holes are provided in the docking groove 172 of the upper shell 16 and the lower shell 171, and the holes are used to facilitate the connection between the cut surface plug-in block 1 282 and the cut surface plug-in block 2 283; the cut surface plug-in block 2 283 is connected to the upper shell 16, and the cut surface plug-in block 1 282 is connected to the lower shell 171, but the cut surface plug-in block 2 283 is connected to the inside of the upper shell 16 in order to release the T-shaped piece 174 in the upper shell 16, and therefore does not support the weight of the upper shell 16 after the cut surface plug-in block 2 283 is connected.

[0045] Reference Figure 2-Figure 8 In a further embodiment, plug-in grooves 183 are provided on both sides of the receiving ring shell 181, and both sides of the hook 184 are rotatably connected to the inner wall of the plug-in groove 183. Torsion springs 185 are provided on both sides of the hook 184, and the torsion spring 185 is used to reset the hook 184, and the hook 184 fits into the inside of the docking groove 172.

[0046] It should be noted that there are convex shafts fixedly connected on both sides of the hook 184, and the hook 184 also relies on the convex shaft to rotate, but can only rotate to a certain angle. The torsion spring 185 is surrounded by the outer periphery of the convex shaft. One end of the torsion spring 185 is inserted into the hook 184, and the other end is inserted into the inner wall of the plug-in slot 183. Therefore, the hook 184 can always be in a vertical state unless the plug-in block 281 is inserted into the inside of the plug-in slot 183.

[0047] Reference Figure 2-Figure 9In a further embodiment, a slide groove 22 is opened on one side of the support column 21 close to the base 15, the bottom end of the limiting column 24 is fixedly connected to the inner wall of the slide groove 22, the top end of the limiting column 1 23 is fixedly connected to the inner wall of the slide groove 22, the two sides of the slider 1 25 and the slider 2 26 are slidably connected inside the slide groove 22, and the lever assembly 29 is slidably connected inside the support column 21.

[0048] It should be noted that the cross-section of slider 1 25 and slider 2 26 is in the shape of an I, so that the limiting column 1 23 and the limiting column 24 can penetrate, and the plug-in block 281 and the cut-surface plug-in block 1 282 can slide. In addition, slider 1 25 and slider 2 26 are slidably connected inside the slide groove 22 through a dovetail block.

[0049] Reference Figure 2-Figure 10 In a further embodiment, the limiting column 1 23 is fixedly connected above the limiting column 24, the slider 1 25 is located above the slider 2 26, and the upper and lower ends of the slider 2 26 are provided with buffer springs 27, and the buffer springs 27 surround the periphery of the limiting column 1 23 and the limiting column 2 24.

[0050] It should be noted that the diameter of the limiting column 1 23 is smaller than that of the limiting column 24. Therefore, after the slider 1 25 moves downward due to gravity, it can only be located at the top of the limiting column 24, while the slider 26 can be located at the bottom of the slide 22, but both are buffered by the buffer spring 27 when moving downward. After the staff completes the maintenance and inspection of the smoke alarm, as long as the lower shell 171 is pushed upward, the lower shell 171 will first contact with the receiving assembly 18, and then the receiving ring shell 181 will contact with the upper shell 1 6, at this time, due to the lifting, the weight of the entire lower monitoring component 17 and the receiving component 18 is no longer applied to the plug-in block 281 and the cut-surface plug-in block 1 282. At this time, the plug-in block 281 and the cut-surface plug-in block 1 282 are retracted to the inside of the slide groove 22 under the action of the return spring 284. Therefore, the hook 184 is lowered and quickly connected to the docking groove 172 under the action of the torsion spring 185, and the T-shaped piece 174 in the docking groove 172 will also quickly engage the hook 184 at this time.

[0051] Reference Figure 2-Figure 11In a further embodiment, the lever assembly 29 includes a connecting rod 291, a connecting plate 293, a stop block 1 294, a stop block 295 and a stop block 3 296. The stop block 1 294 fits one end of the cut surface plug block 283. The stop block 295 is located on both sides of the slider 1 25 and fits one end of the plug block 281. The stop block 3 296 is located on both sides of the slider 26 and fits both sides of the cut surface plug block 1 282. The stop block 1 294, the stop block 295 and the stop block 3 296 are all fixedly connected to one side of the connecting plate 293. One end of the connecting rod 291 is fixedly connected to the connecting plate 293. One end of the connecting plate 293 away from the connecting rod 291 fits both sides of the base 15. The connecting rod 291 is located inside the support column 21 and is surrounded by a return spring 3 292. The return spring 3 292 is used to reset the entire lever assembly 29.

[0052] It should be noted that card interfaces are provided on both sides of the base 15, so that when the support mechanism 2 is not needed, one end of the connecting plate 293 can be plugged in, thereby preventing the support mechanism 2 from affecting the normal use of the alarm body 1; a pull ring is provided at one end of the connecting rod 291 for facilitating the pulling of the entire lever assembly 29; the distance between the first block 294, the second block 295 and the third block 296 can just allow the first block 294 to push the cut surface plug block 283 and the third block 296 to push the cut surface plug After the block 1 282 is pushed, the second block 295 pushes the plug-in block 281; the lower ends of the blocks 1 294, 295 and 3 296 have beveled surfaces, so when they move downward, they will push the cut surface plug-in block 2 283, the cut surface plug-in block 1 282 and the plug-in block 281; when the lever assembly 29 is pulled down as a whole for the first time, it is convenient to rotate the entire support mechanism 2 ninety degrees, and after being pulled down, the upper end of the connecting plate 293 will resist the ceiling, thereby ensuring that the support mechanism 2 is continuously in a ninety-degree state.

[0053] Reference Fig.11 In a further embodiment, the plug-in assembly 28 includes a plug-in block 281 and a cut-surface plug-in block 1 282, the plug-in block 281 fits into the interior of the plug-in slot 183, the receiving block 182 fits into the docking slot 172 of the lower shell 171, the cut-surface plug-in block 283 fits into the docking slot 172 of the upper shell 16, and the cut-surface plug-in block 283 is slidably connected to the interior of the support column 21.

[0054] It should be particularly noted that the cut surface plug block 283 is symmetrical to the cut surface plug block 1 282, and there is also a return spring 284 at the cut surface plug block 283; after one end of the plug block 281 is inserted into the interior of the plug slot 183, the hook 184 will rotate ninety degrees, so that one end of the hook 184 can come out from the interior of the docking slot 172, thereby facilitating the separation of the upper shell 16, the receiving component 18 and the lower monitoring component 17.

[0055] Reference Figure 2-Figure 10In a further embodiment, the plug-in block 281 is slidably connected to the inside of the slider 1 25, the cut-surface plug-in block 1 282 is slidably connected to the inside of the slider 2 26, and the sliding connection between the plug-in block 281 and the cut-surface plug-in block 1 282 is fixedly connected with a return spring 284.

[0056] It should be particularly noted that the plug-in block 281 is composed of a plug-in block and two symmetrical bars, wherein the bars are used for sliding connection, and the upper and lower parts of the bars are used to place the reset spring 284, so that when the plug-in block 281 is plugged into the inside of the plug-in slot 183 and no longer bears the overall weight of the receiving assembly 18, the plug-in block 281 can be pulled out from the inside of the plug-in slot 183; the cut-surface plug-in block 1 282 is the same as the plug-in block 281, but the plug connector of the cut-surface plug-in block 1 282 has an oblique surface, so that the T-shaped piece 174 can be pushed so that the T-shaped piece 174 no longer engages the position of the hook 184.

[0057] The working principle of the present invention is as follows:

[0058] After the smoke is generated and floats to the ceiling, the smoke will follow the periphery of the base 15 and enter the interior of the upper shell 16 and the monitoring box 13 in turn. The smoke will block the light emitted by the infrared light source of the circuit board 11, allowing the photosensitive element to detect the change. As the smoke continues to pass through the periphery of the receiving component 18 and enter the monitoring box 13 in the lower monitoring component 17, it will be monitored again. When the average value of the monitoring box 13 in the upper shell 16 and the lower monitoring component 17 is greater than the set alarm threshold, the buzzer in the receiving component 18 will be activated, and an alarm will be sounded to remind people.

[0059] When maintenance is needed after a certain period of use, the staff can stand at a high place with a ladder or other tools and pull the connecting rod 291 once, so that one end of the connecting plate 293 is separated from the inside of the base 15, and then the support column 21 can rotate 90 degrees with the plug assembly 28 and the lever assembly 29, so that the support mechanism 2 is perpendicular to the base 15 as a whole. Then, the connecting rod 291 is pulled again to move the connecting plate 293 downward again. During the downward movement of the connecting plate 293, the first block 294 and the third block 294 are engaged with each other. 6 First, the cut surface plug block 283 and the cut surface plug block 1 282 are pushed respectively, so that the cut surface plug block 283 and the cut surface plug block 1 282 are respectively inserted into the docking grooves 172 on both sides of the upper shell 16 and the docking grooves 172 on both sides of the lower shell 171, and then the T-shaped piece 174 inside the upper shell 16 is moved up, and the T-shaped piece 174 inside the lower shell 171 is moved down, so that the T-shaped piece 174 is no longer engaged with the hook 184, and then the connecting plate 293 moves down to allow the second block 295 to push the plug block 28 1 is connected to the inside of the plug-in slot 183 and the hook 184 is no longer connected to the upper shell 16 and the lower shell 171. At this time, the entire receiving assembly 18 and the circuit board 11 placed inside are all received on the top of the plug-in block 281, and the lower monitoring assembly 17 and the monitoring box 13 placed inside are all received on the top of the stop block 3 296. There is no connection between the receiving ring shell 181 and the upper shell 16 and between the receiving ring shell 181 and the lower shell 171. Under the action of gravity, the receiving assembly 18 is brought Slider 1 25 and lower monitoring assembly 17 fall with slider 2 26 at the same time, but during the falling process, slider 1 25 can only reach the bottom end of limiting column 1 23, and slider 2 26 can reach the bottom end of limiting column 24, and both are buffered by buffer spring 27 when falling, thereby allowing the upper shell 16, receiving ring shell 181 and lower shell 171 to separate from each other, making it convenient for staff to maintain the monitoring box 13 in the upper shell 16 and the lower shell 171, as well as the circuit board 11 inside the receiving ring shell 181.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
