Description

Technical Field

[0001] This utility model relates to the field of smoke detection alarm technology, and in particular to an intelligent smoke detection alarm. Background Technology

[0002] A smart smoke detector is a high-tech safety device designed to detect smoke in the environment and quickly issue an alarm to prevent damage from fires. Using highly sensitive photoelectric or ionization sensors, the smart smoke detector can detect tiny smoke particles produced by combustion. Once smoke is detected, the alarm immediately sounds an audible and visual alarm to alert people to take action.

[0003] The smoke and dust detected by smoke detectors are fundamentally different. The particulate matter in smoke is usually tiny, while dust is mainly composed of solid particles. These particles can contaminate the detector and usually require a dust cover. However, after prolonged use, dust can easily accumulate on the dust cover, making it difficult for smoke to pass through and thus reducing the sensitivity of the smoke detector. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an intelligent smoke detector alarm.

[0005] The technical solution of this utility model: An intelligent smoke detector alarm, comprising a housing and a dust cover fixedly installed on the housing, wherein multiple dust filters are installed on the dust cover, and further comprising:

[0006] A dust removal mechanism is installed inside the dust removal hood, and the dust removal mechanism beats the dust removal screen.

[0007] An air blowing mechanism installed inside the dust collector hood blows air onto the dust collector screen from inside the dust collector hood.

[0008] Optionally, the dust removal mechanism includes a rotating plate rotatably installed inside the dust removal hood, a support ring fixedly installed on the rotating plate, a plurality of tapping plates rotatably installed on the support ring, and an elastic connecting member between the tapping plates and the rotating plate.

[0009] Optionally, the elastic connector includes a connecting block fixedly installed on the beater plate, a first spring fixedly installed on the connecting block, a plurality of support seats fixedly installed on the rotating plate, the support seats corresponding one-to-one with the first spring and fixedly connected, and an energy storage component for driving the rotating plate to rotate is installed inside the dust collector hood.

[0010] Optionally, a plurality of protrusions are fixedly installed inside the dust removal hood, the protrusions being located below the dust removal mesh, and the bottom of the connecting block having rounded corners.

[0011] Optionally, the energy storage component includes a rotating shaft rotatably mounted inside a dust collector, a sliding rod slidably mounted on the rotating shaft, a torsion spring fixedly mounted on the rotating shaft, the other end of the torsion spring being fixedly connected to the dust collector, a connector fixedly mounted on the sliding rod, a second spring movably mounted between the rotating shaft and the sliding rod, and a connecting sleeve fixedly mounted on the rotating plate, the connecting sleeve having a connecting groove.

[0012] Optionally, the air blowing mechanism includes an airbag fixedly installed inside the dust collector hood, the airbag having an air inlet, a one-way valve fixedly installed inside the air inlet, and an air blowing head fixedly installed inside the dust collector hood and on one side of the dust collector screen, the air blowing head communicating with the airbag, and a valve being provided between the airbag and the air blowing head.

[0013] Optionally, the valve includes a housing fixedly installed in the dust collector hood, with both ends of the housing connected to the air blower and the air bag respectively. A blocking block is slidably installed inside the housing, and a pull rod is fixedly installed on the blocking block. Multiple pull rods are fixedly connected by a connecting plate.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This invention uses a dust removal mechanism to beat the dust removal screen, which, due to inertia, separates the dust from the screen, thus removing the dust.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 6 As shown, the present invention proposes an intelligent smoke detector alarm, including a housing 1 and a dust cover 2 fixedly installed on the housing 1. The dust cover 2 is equipped with multiple dust filters 201. Smoke will enter the dust filter 201 through the dust filter 201 and be detected by the smoke detection component inside the housing 1 (the smoke detection component is prior art and will not be described in detail here). The dust filter 201 can block large dust particles, prevent dust from interfering with the smoke detection component, and avoid dust contamination of the smoke detection component.

[0026] This embodiment also includes a dust removal mechanism installed inside the dust removal hood 2. The dust removal mechanism beats the dust removal screen 201. The dust removal mechanism includes a rotating plate 3 rotatably installed inside the dust removal hood 2. A support ring 301 is fixedly installed on the rotating plate 3, and multiple beating plates 302 are rotatably installed on the support ring 301. An elastic connector is provided between the beating plates 302 and the rotating plate 3. By rotating the rotating shaft 4, the multiple beating plates 302 can be driven to rotate. The rotating beating plates 302 will rotate on the dust removal screen 201. The elastic connector ensures that the beating plates 302 always abut against the dust removal screen 201. The elastic connector includes a connecting block 303 fixedly installed on the beating plate 302. A first spring 304 is fixedly installed on the connecting block 303. Multiple support seats 305 are fixedly installed on the rotating plate 3. The support seats 305 correspond one-to-one with the first springs 304 and are fixedly connected. An energy storage component that drives the rotating plate 3 to rotate is installed inside the dust removal hood 2. The first spring 304 can apply pressure to the beater plate 302, causing the beater plate 302 to abut against the dust removal net 201, and the energy storage component can make the rotating plate 3 rotate.

[0027] Furthermore, multiple protrusions 306 are fixedly installed inside the dust collector hood 2, located below the dust collector screen 201, and the bottom of the connecting block 303 is rounded. When the rotating beater 302 contacts the protrusions 306, the beater 302 will rotate. After the beater 302 disengages from the protrusions 306, it will beat the dust collector screen 201 under the action of the first spring 304. Under the action of inertia, the dust will be separated from the dust collector screen 201, thereby removing the dust from the dust collector screen 201.

[0028] The energy storage component includes a rotating shaft 4 rotatably installed inside the dust collector 2, a sliding rod 401 slidably installed on the rotating shaft 4, a torsion spring 402 fixedly installed on the rotating shaft 4, the other end of the torsion spring 402 being fixedly connected to the dust collector 2, a connector 403 fixedly installed on the sliding rod 401, a second spring 404 movably installed between the rotating shaft 4 and the sliding rod 401, and a connecting sleeve 405 fixedly installed on the rotating plate 3, with a connecting groove 406 provided on the connecting sleeve 405. Rotating and pulling down the slide bar 401 will drive the rotating shaft 4, which has circumferential positioning with it, to rotate. The rotating shaft 4 will drive the torsion spring 402 to rotate, and the torsion spring 402 can store kinetic energy. When the slide bar 401 is released, the connector 403 will be driven to rise under the action of the second spring 404. The rising connector 403 will enter the connecting groove 406. Since the connector 403 and the connecting groove 406 have circumferential positioning, the rotating shaft 4 can drive the rotating plate 3 to rotate, and then the rotating plate 3 can drive the beater plate 302 to remove dust from the dust removal screen 201.

[0029] This embodiment also includes an air blowing mechanism installed inside the dust collection hood 2. The air blowing mechanism blows air onto the dust collection screen 201 from inside the dust collection hood 2. When the dust collection screen 201 is tapped, dust on the screen may enter the interior of the dust collection hood 2. At this time, blowing air outward from inside the dust collection hood 2 can prevent dust from entering the interior of the dust collection hood 2, ensuring that dust will not interfere with the smoke detection component. The air blowing mechanism includes an air bag 5 fixedly installed inside the dust collection hood 2. The air bag 5 is provided with an air inlet 501, and a one-way valve is fixedly installed inside the air inlet 501. An air blowing head 502 is fixedly installed inside the dust collection hood 2 and on one side of the dust collection screen 201. The air blowing head 502 is connected to the air bag 5, and a valve is provided between the air bag 5 and the air blowing head 502. The airbag 5 can be inflated through the air inlet 501. After inflation, the airbag 5 can be discharged through the air blower 502 by opening the valve, so that the air blower 502 can blow air onto the dust filter 201 inside the dust filter hood 2.

[0030] Furthermore, the valve includes a housing 503 fixedly installed in the dust collector hood 2. Both ends of the housing 503 are connected to the air blower 502 and the air chamber 5, respectively. A blocking block 504 is slidably installed inside the housing 503, and a pull rod 505 is fixedly installed on the blocking block 504. Multiple pull rods 505 are fixedly connected by a connecting plate 506. The blocking block 504 seals the interior of the housing 503. When the connecting plate 506 is pulled downwards, the blocking block 504 will move downwards, thereby releasing the blockage and allowing the gas inside the air chamber 5 to be discharged through the air blower 502. The blocking block 504 and the housing 503 have a damping effect, eliminating the need for additional positioning components.

[0031] The working principle of this embodiment is as follows: Rotating and pulling down the slide rod 401 will drive the rotating shaft 4, which has circumferential positioning with it, to rotate. The rotating shaft 4 will drive the torsion spring 402 to rotate, and the torsion spring 402 can store kinetic energy. When the slide rod 401 is released, the connector 403 will be driven to rise under the action of the second spring 404. The rising connector 403 will enter the connecting groove 406. Since the connector 403 and the connecting groove 406 have circumferential positioning, the rotating shaft 4 can drive the rotating plate 3 to rotate, and then the rotating plate 3 can drive the beater plate 302 to remove dust from the dust removal screen 201.

[0032] The airbag 5 can be inflated through the air inlet 501. After inflation, the airbag 5 can be discharged through the air blower 502 by opening the valve, which in turn allows the dust cover inside the air blower 502 to blow air onto the dust filter 201.

[0033] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
