[0004] However, the current embedded fireproof LED spotlight has the following problem: after a fire occurs, the alarm device will not burn completely because the protective cover blocks some air, producing small carbon black particles that adhere to the protective cover, causing the alarm device to lose its light warning function. Therefore, we propose an embedded fireproof LED spotlight. Utility Model Content

[0005] The purpose of this invention is to provide an embedded fireproof LED spotlight that can solve the problem in related technologies where, after a fire, the protective cover blocks some air, causing incomplete combustion and producing small carbon black particles that adhere to the protective cover, thus rendering the alarm device ineffective in its light warning function.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An embedded fireproof LED spotlight includes an embedded base, a fireproof transparent cover fixedly connected to the top of the embedded base, a fireproof sensing component provided on the top of the embedded base, a scraping device provided on the circumferential surface of the embedded base, the scraping device including a motor bracket, the side of the motor bracket fixedly connected to the circumferential surface of the embedded base, a driving component provided at the bottom of the motor bracket, and a cleaning scraper fixedly connected to the driving end of the driving component.

[0008] The fire-proof sensing component also includes a spotlight fixedly connected to the top of the drive base, a rotating rod rotatably connected to the top of the embedded base, a temperature sensing block fixedly connected to the top of the rotating rod, a smoke sensing block fixedly connected to the top of the temperature sensing block, and a refractive prism fixedly connected to the circumferential surface of the rotating rod.

[0009] The drive assembly also includes a drive motor fixedly connected to the bottom of the motor bracket. The output shaft of the drive motor is fixedly connected to a rotating shaft. A rotating ring is rotatably connected to the circumferential surface of the fireproof transparent cover. A drive track is connected between the rotating shaft and the rotating ring. The rotating ring is the drive end of the scraping device.

[0010] The inner wall of the cleaning scraper is in contact with the outer wall of the fireproof transparent cover, and a gap is provided between the outer wall of the temperature sensing block and the inner wall of the cleaning scraper.

[0011] A disconnection device is provided on the circumferential surface of the rotating ring. The disconnection device includes a push plate, the side of which is fixedly connected to the circumferential surface of the rotating ring. A connecting point pipe is passed through and fixedly connected to the circumferential surface of the embedded base. A convex groove straight block is fixedly connected to the circumferential surface of the embedded base. A reset rod is passed through and slidably connected to the bottom of the groove of the convex groove straight block. A slanted cone slider is fixedly connected to the top of the reset rod. A lifting spring is provided between the slanted cone slider and the bottom of the groove of the convex groove straight block. An elastic telescopic rod is fixedly connected to the circumferential surface of the embedded base. A connecting plate is fixedly connected to the telescopic end of the elastic telescopic rod. A locking block is fixedly connected to the bottom of the connecting plate. An external wiring pipe is passed through and fixedly connected to the side of the connecting plate.

[0012] The bottom of the locking block is a tapered surface, and the top of the tapered slider is a tapered surface. The bottom of the locking block is in contact with the top of the tapered slider.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention, through the setting of a scraping device, enables the motor bracket, drive motor, rotating shaft, rotating ring, drive track, and cleaning scraper to work together. The rotation of the rotating ring drives the cleaning scraper to rotate, so that the cleaning scraper can scrape off small carbon black particles on the fireproof transparent cover, ensuring that the alarm will not lose its alarm function due to excessive fire.

[0015] This invention, through the setting of a disconnection device, enables the push plate, connecting point pipe, convex straight block, reset rod, inclined cone slider, lifting spring, elastic telescopic rod, connecting plate, locking block, and external wiring pipe to reset the inclined cone slider and lock the connecting plate. This ensures that the connecting plate and the connecting point pipe are disconnected before manual reset. After the fire alarm ends, manually pulling the reset rod downwards causes the inclined cone slider to slide, simultaneously pushing the connecting plate to connect with the connecting point pipe. This prevents short circuits in the internal wiring caused by high temperatures at the wiring points, which could lead to power system failure. Attached Figure Description

Detailed Implementation

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-5As shown, an embedded fireproof LED spotlight includes an embedded base 1, a fireproof transparent cover 2 fixedly connected to the top of the embedded base 1, a fireproof sensing component provided on the top of the embedded base 1, a scraping device 8 provided on the circumferential surface of the embedded base, the scraping device 8 including a motor bracket 81, the side of the motor bracket 81 fixedly connected to the circumferential surface of the embedded base 1, a driving component provided at the bottom of the motor bracket 81, and a cleaning scraper 86 fixedly connected to the driving end of the driving component.

[0025] The fire-sensing component also includes a spotlight 3 fixedly connected to the top of the drive base 1, a rotating rod 4 rotatably connected to the top of the base 1, a temperature sensing block 5 fixedly connected to the top of the rotating rod 4, a smoke sensing block 6 fixedly connected to the top of the temperature sensing block 5, and a refraction prism 7 fixedly connected to the circumferential surface of the rotating rod 4. The refraction prism 7 enables the spotlight 3 to increase its illumination range, ensuring that the alarm can be quickly transmitted and spread.

[0026] The drive assembly also includes a drive motor 82 fixedly connected to the bottom of the motor bracket 81. The output shaft of the drive motor 82 is fixedly connected to a rotating shaft 83. A rotating ring 84 is rotatably connected to the circumferential surface of the fireproof transparent cover 2. A drive track 85 is connected between the rotating shaft 83 and the rotating ring 84. The rotating ring 84 is provided as the drive end of the scraping device 8.

[0027] The inner wall of the scraper 86 is in contact with the outer wall of the fireproof transparent cover 2. The outer wall of the temperature sensing block 5 is provided with a gap between the inner wall of the scraper 86 and the scraper 86 so that the scraper 86 will not damage the temperature sensing block 5 when it scrapes the fireproof transparent cover 2.

[0028] According to the above structure, when a fire occurs, the drive motor 82 starts, and the output rotation of the drive motor 82 drives the rotating shaft 83 to rotate. The rotation of the rotating shaft 83 drives the drive track 85, the rotation of the drive track 85 drives the rotating ring 84 to rotate, and the rotation of the rotating ring 84 drives the cleaning scraper 86 to rotate, so that the cleaning scraper 86 can scrape off the small carbon black particles on the fireproof transparent cover 2, so that the alarm will not lose its alarm function due to the fire being too large.

[0029] like Figure 1-5As shown, a disconnection device 9 is provided on the circumferential surface of the rotating ring 84. The disconnection device 9 includes a push plate 91, the side of which is fixedly connected to the circumferential surface of the rotating ring 84. A connecting point pipe 92 is fixedly connected through and embedded in the circumferential surface of the base 1. A convex groove straight block 93 is fixedly connected to the circumferential surface of the base 1. A reset rod 94 is slidably connected through and through the bottom of the groove of the convex groove straight block 93. A conical slider 95 is fixedly connected to the top of the reset rod 94. A lifting spring 96 is provided between the conical slider 95 and the bottom of the groove of the convex groove straight block 93. An elastic telescopic rod 97 is fixedly connected to the circumferential surface of the base 1. A connecting plate 98 is fixedly connected to the telescopic end of the elastic telescopic rod 97. A locking block 99 is fixedly connected to the bottom of the connecting plate 98. An external wiring pipe 910 is fixedly connected through and through the side of the connecting plate 98. Contact when no fire occurs can ensure the normal operation of the alarm device and ensure that a fire can be detected immediately when it occurs.

[0030] The bottom of the locking block 99 is set with a sloping conical surface, and the top of the sloping conical slider 95 is set with a sloping conical surface. The bottom of the locking block 99 is in contact with the top of the sloping conical slider 95. The sloping conical surface can increase the squeezing opening and closing efficiency and ensure timely disconnection.

[0031] According to the above structure, the rotating ring 84 drives the push plate 91 to rotate. When the push plate 91 rotates, it applies a force to the connecting plate 98 in a direction away from the connecting point pipe 92, causing the connecting plate 98 to slide away from the connecting point pipe 92, thereby disconnecting the connection between the connecting plate 98 and the connecting point pipe 92. The sliding of the connecting plate 98 away from the connecting point pipe 92 causes the locking block 99 to slide away from the connecting point pipe 92 and press the inclined cone slider 95. After the connecting plate 98 slides past the inclined cone slider 95, it is subjected to the reverse force of the lifting spring 96, causing the inclined cone slider 95 to reset and lock the connecting plate 98. This ensures that the connecting plate 98 and the connecting point pipe 92 are in a disconnected state before manual reset. After the fire alarm ends, the reset rod 94 is manually pulled down and slids down. The downward sliding of the reset rod 94 causes the inclined cone slider 95 to slide, and at the same time pushes the connecting plate 98, connecting the connecting plate 98 to the connecting point pipe 92. This prevents the internal wiring from short-circuiting due to the high temperature at the wiring point, which could lead to the paralysis of the power supply system.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
