DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in the present embodiment, an intelligent ventilation and smoke exhaust device includes a ventilation duct 1, a mounting frame 2 is fixedly connected to the interior of the ventilation duct 1, a ventilation fan 6 is fixedly installed to the interior of the mounting frame 2, a smoke sensor 7 is fixedly installed to the top of the ventilation duct 1, a filter assembly is arranged inside the ventilation duct 1, a fixing block 14 is fixedly connected to the bottom of the ventilation duct 1, a slide groove 18 is provided inside the fixing block 14, a limiting assembly is arranged inside the slide groove 18, a first inclined plate 9 is fixedly connected to the interior of the ventilation duct 1, and a second inclined plate 10 is fixedly connected to the interior of the ventilation duct 1.

[0022] Firstly, the smoke sensor 7 can detect whether there is smoke in the room. After detecting the presence of smoke, the smoke sensor 7 sends a command to the ventilation fan 6, so as to perform smoke exhaust and ventilation operations on the smoke in the room, thereby realizing intelligent smoke exhaust operation. Then, when exhausting smoke, the first inclined plate 9 and the second inclined plate 10 cooperate to increase the time the smoke stays in the ventilation duct 1, thereby cooling the high temperature in the smoke to a certain extent, thereby reducing the impact of the high-temperature smoke on the ventilation fan 6. Then, the dust in the smoke is filtered through the filter component, thereby avoiding the problem that the dust in the smoke will adhere to the surface of the ventilation fan 6, thereby reducing the ventilation and smoke exhaust effect and increasing the service life of the ventilation fan 6. Then, the filter component can also prevent external mosquitoes from entering the ventilation duct 1, thereby further increasing the practicality of the device. When the filter component needs to be replaced and cleaned, the filter component can be quickly disassembled by toggling the limit component. Then, when installing, it is only necessary to insert the filter component into the ventilation duct 1, so that the filter component can be automatically locked by the limit component, thereby increasing the efficiency of installation.

[0023] like Figure 1-Figure 4As shown, the filter assembly includes a mounting plate 11, which is slidably connected to the inside of the ventilation duct 1, and a second filter screen 8 is arranged inside the mounting plate 11. The filter assembly also includes a sealing strip 12, and the sealing strip 12 is arranged on the outside of the mounting plate 11. A fixing frame 5 is arranged on one side of the ventilation duct 1, and a first filter screen 3 is arranged inside the fixing frame 5. Bolts 4 are equidistantly arranged on the outside of the fixing frame 5.

[0024] When filtering the smoke, the dust in the smoke is filtered through the second filter 8, and then the sealing strip 12 can prevent the smoke from leaking out from the connection of the mounting plate 11. Then, the first filter 3 can prevent external mosquitoes from entering the ventilation duct 1 and affecting the ventilation fan 6.

[0025] like Figure 1-Figure 4 As shown, the limit assembly includes a slider 19, which is slidably connected to the inside of the slide groove 18, and a spring 17 is fixedly connected between one side of the slider 19 and the slide groove 18. The limit assembly also includes a clamping block 20, which is slidably connected to the inside of the fixed block 14, and one end of the clamping block 20 is fixedly connected to one side of the slider 19. A mounting groove 21 is provided on one side of the fixed block 14, and a protrusion 13 is fixedly connected to one side of the mounting plate 11. A limit groove 15 is penetrated through one side of the fixed block 14, and a lever 16 is slidably connected to the inside of the limit groove 15, and one end of the lever 16 is fixedly connected to one side of the slider 19.

[0026] When replacing the second filter 8, the lever 16 is pushed to slide inside the limiting groove 15, while driving the slider 19 to move, and then driving the block 20 to move, thereby releasing the restriction of the protrusion 13 inside the mounting groove 21. In this way, the mounting plate 11 can be conveniently pulled out for replacement and cleaning. Then, when installing the second filter 8, the mounting plate 11 is inserted into the ventilation duct 1, and then the protrusion 13 enters the inside of the mounting groove 21 and contacts the inclined surface of the block 20, thereby driving the block 20 to move and driving the slider 19 to compress the spring 17. After the protrusion 13 completely enters the inside of the mounting groove 21, the block 20 is driven to move under the reaction force of the spring 17, thereby limiting and fixing the protrusion 13.

[0027] The utility model provides an intelligent ventilation and smoke exhaust device, and the specific working principle is as follows: first, the smoke sensor 7 can detect whether there is smoke in the room. After detecting the presence of smoke, the smoke sensor 7 sends a command to the ventilation fan 6, so that the smoke in the room is exhausted and ventilated, thereby realizing intelligent smoke exhaust operation, and then when exhausting smoke, the first inclined plate 9 and the second inclined plate 10 are cooperated to make the smoke stay in the ventilation duct 1 for a certain period of time, so as to cool the high temperature in the smoke to a certain extent, thereby reducing the influence of the high-temperature smoke on the ventilation fan 6, and then the dust in the smoke is filtered through the second filter 8, and then the sealing strip 12 can prevent the smoke from being exposed from the connection of the mounting plate 11, and then the first filter 3 can be used to place the external mosquito net. Insects enter the ventilation duct 1 and affect the ventilation fan 6. Finally, when replacing the second filter 8, the lever 16 is pushed to slide in the limiting groove 15 and the slider 19 is moved, and then the block 20 is moved, thereby releasing the restriction of the protrusion 13 in the mounting groove 21. In this way, the mounting plate 11 can be easily pulled out for replacement and cleaning. Then, when installing the second filter 8, the mounting plate 11 is inserted into the ventilation duct 1, and then the protrusion 13 enters the mounting groove 21 and contacts the inclined surface of the block 20, thereby driving the block 20 to move and driving the slider 19 to compress the spring 17. After the protrusion 13 completely enters the mounting groove 21, the block 20 is moved under the reaction force of the spring 17, thereby limiting and fixing the protrusion 13.
