Description

Technical Field

[0001] This utility model relates to the field of fire detection equipment technology, specifically to a flame detector. Background Technology

[0002] A fire detector is a device used to detect fires. It determines whether a fire has occurred by detecting various physical quantities generated when a fire occurs, such as smoke, gases, temperature, and radiation. Fire detectors are widely used in various places, such as industrial, commercial, and residential settings, to protect people's lives and property. The window is a crucial component of a fire detector. Its function is to allow the detector to receive the various physical quantities generated when a fire occurs, convert them into electrical signals, and then transmit them to the alarm controller, ultimately achieving fire detection and alarm activation.

[0003] However, in existing technologies, flame detectors are usually installed outdoors or in industrial environments. Dust and particulate matter in these environments can easily adhere to the flame detector. If the dust accumulates on the surface of the filter glass window of the flame detector, it will affect the detector's reception and transmission of fire signals. These contaminants will absorb or scatter the radiation generated by the fire, weakening or interfering with the signal received by the detector, thus leading to false alarms or missed alarms and affecting the performance of the detector. Therefore, there is a need for a flame detector that can easily remove dust adhering to the surface of the glass window.

[0004] This invention proposes a flame detector to solve the above-mentioned problems. Utility Model Content

[0017] Start the drive unit 4, which drives the rotating part 5 to rotate. The rotating part 5 drives the soft brush 6 to rotate, thereby removing dust from the surface of the protective cover 12. The falling dust can fall down along the rotating part 5.

[0018] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The driving component 4 includes a rotary motor 401 and a drive gear 402. The rotary motor 401 is connected to the side wall of the support block 3, and the drive gear 402 is connected to the output end of the rotary motor 401. The rotating component 5 includes a rotating ring 501, a driven gear 502, an annular cut surface 503, and a through hole 504. The rotating ring 501 is rotatably connected to the side wall of the detector body 1. An annular cut surface 503 is opened on the inner side wall of one end of the rotating ring 501, and a through hole 504 is opened on the side wall of the rotating ring 501. The driven gear 502 is connected to the outer side wall of the other end of the rotating ring 501. The moving gear 502 meshes with the driving gear 402. The annular cross-section 503 is shaped like a frustum. One end of the annular cross-section 503 is flush with the end of the detector body 1 facing the glass window 2. The annular cross-section 503 is located on the periphery of the detector body 1. A surrounding plate can be connected to the periphery of the support block 3. The soft brush 6 can be connected to the inside of the through hole 504. The through hole 504 is located between the driven gear 502 and the port of the annular cross-section 503. The side of the soft brush 6 near the protective cover 12 is arc-shaped. The side of the soft brush 6 near the protective cover 12 can fit against the surface of the protective cover 12.

[0019] Start the rotary motor 401, which causes the drive gear 402 to drive the driven gear 502 to rotate, thereby driving the rotating ring 501 to rotate. The rotating ring 501 drives the through hole 504 to rotate, so that the soft brush 6 can remove dust from the surface of the protective cover 12. The removed dust will fall onto the annular cut surface 503. By using the inclined surface of the annular cut surface 503, the dust can fall to the ground along the annular cut surface 503, thus achieving the effect of conveniently removing dust from the surface of the protective cover 12.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 An adjusting component 7 is installed on the side wall of the rotating ring 501. The adjusting component 7 includes a push rod motor 701 and a bracket 702. One end of the bracket 702 is connected to the outer side wall of the rotating ring 501. The inner bottom end of the bracket 702 is connected to the push rod motor 701. The output end of the push rod motor 701 is connected to the bottom end of the soft brush 6. The soft brush 6 can pass through the through hole 504. A scraper 8 is connected to the side wall of the through hole 504 near the detector body 1. The bracket 702 can wrap the push rod motor 701 and has heat dissipation holes on its surface.

[0021] When the soft brush 6 needs to remove dust from the surface of the glass window 2, simply activate the push rod motor 701 to push the soft brush 6 from the outside of the rotating ring 501 to the inside of the rotating ring 501, so that the soft brush 6 can remove dust from the surface of the glass window 2. After the dust removal is completed, use the push rod motor 701 to pull the soft brush 6 from the inside of the rotating ring 501 to the outside of the rotating ring 501, thereby avoiding the soft brush 6 from blocking the glass window 2 and avoiding interference with the detection of the detector body 1. Furthermore, when the soft brush 6 is pulled out to the outside of the rotating ring 501, the soft brush 6 will be scraped off by the scraper block 8 to reduce the dust adhering to the surface of the soft brush 6.

[0022] refer to Figure 7 The detector body 1 has a slot 11 on its port surface. A support plate 9 is inserted into the slot 11 and fastened. The connection between the slot 11 and the support plate 9 can be a flexible snap-fit ​​connection or a screw-fixed connection. The support plate 9 or the protective cover 12 can be equipped with a detachable magnetic cleaning ring. The snap-fit ​​connection allows the support plate 9 to be easily removed from the slot 11. A glass window 2 is connected to the support plate 9. The glass window 2 is composed of a tempered glass substrate, a hydrophobic nano-coating, and an infrared anti-reflection filter. The hydrophobic nano-coating has a static contact angle ≥150° and a dynamic roll-off angle ≤10°. The glass window 2 penetrates the support plate 9. A spiral guide groove 10 is formed on the outer surface of the protective cover 12. The spiral guide groove 10 has an inclination angle of 15° to 30°.

[0023] When the protective cover 12 is directly rinsed by the water gun, the water can be quickly discharged along the hydrophobic surface of the glass window 2 by utilizing the arc-shaped convex surface of the protective cover 12. Then, the water remaining after rinsing can flow out of the protective cover 12 along the spiral guide groove 10, making it convenient to drain the remaining water.

[0024] The working principle and usage process of this utility model are as follows: In specific use, the rotary motor 401 is started, which causes the drive gear 402 to drive the driven gear 502 to rotate, thereby driving the rotating ring 501 to rotate. The rotating ring 501 drives the through hole 504 to rotate, so that the soft brush 6 can remove dust from the surface of the protective cover 12. The dust removed will fall onto the annular cut surface 503. By utilizing the inclined surface of the annular cut surface 503, the dust can fall to the ground along the annular cut surface 503, thus achieving the effect of conveniently removing dust from the surface of the protective cover 12. When the soft brush 6 needs to remove dust from the surface of the glass window 2, simply activate the push rod motor 701 to push the soft brush 6 from the outside of the rotating ring 501 to the inside of the rotating ring 501, so that the soft brush 6 can remove dust from the surface of the protective cover 12. After the dust removal is completed, use the push rod motor 701 to pull the soft brush 6 from the inside of the rotating ring 501 to the outside of the rotating ring 501, thereby avoiding the soft brush 6 from blocking the glass window 2 and the protective cover 12, and avoiding interference with the detection of the detector body 1. Furthermore, when the soft brush 6 is pulled out to the outside of the rotating ring 501, the soft brush 6 will be scraped off by the scraper block 8 to reduce the dust adhering to the surface of the soft brush 6.
