Description

Technical Field

[0001] This invention relates to the field of ventilation device technology, specifically to a ventilation outlet adjustment device based on the Internet of Things. Background Technology

[0002] Ventilation devices are used to regulate airflow and improve air quality in a space. They are widely used in homes, industries, medical settings, and agriculture. Their core functions include ventilation, cooling, stale air removal, and humidity control. IoT-based ventilation devices represent a deep integration of traditional ventilation equipment with IoT technology. Through data-driven and intelligent decision-making, they achieve precision, automation, and collaboration in the ventilation process. The core is to break away from the passive operation mode of traditional equipment and upgrade to an intelligent system that actively senses, dynamically responds, and optimizes globally. By monitoring environmental parameters in real time through multiple sensors, they dynamically adjust airflow and operating modes, and can record ventilation efficiency and energy consumption data. Their development trend is towards greater precision, efficiency, and safety.

[0003] Ventilation devices are widely used in many fields. In working environments with high concentrations of harmful gases, ventilation fans and ducts are usually used in combination with various harmful gas treatment structures for effective ventilation. However, in the face of the need to treat multiple harmful gases, existing ventilation devices cannot discharge specific gases to designated pipelines. Multiple air inlets in the pipeline are difficult to control independently, and the inlet and outlet cannot be opened and closed synchronously, resulting in the mixed emission of multiple harmful gases. This not only reduces gas treatment efficiency but may also cause secondary pollution.

[0004] Combining the above issues, we find that existing IoT-based ventilation vent adjustment devices struggle to simultaneously avoid these problems during use. Even if they can solve them, they require external tools, thus failing to achieve the desired effect. Therefore, we propose an IoT-based ventilation vent adjustment device. Summary of the Invention

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1-6 The present invention provides a technical solution: a ventilation outlet adjustment device based on the Internet of Things, including a main body 1, the main body 1 including a ventilation fan 12, a ventilation pipe 11 fixedly connected to one side of the ventilation fan 12, and an air outlet adjustment mechanism 2 provided inside the ventilation pipe 11;

[0033] The air outlet regulating mechanism 2 includes an inlet regulating unit 21, which is located inside the ventilation duct 11. The inlet regulating unit 21 is used to open multiple gas pipelines separately to achieve classified treatment of different gases. The inlet regulating unit 21 is based on Internet of Things technology and is equipped with intelligent sensors for real-time monitoring of gas types.

[0034] As a further definition of the air vent adjustment mechanism 2 of the present invention, the inlet adjustment unit 21 includes four processing pipes 2101. The outer surface of each processing pipe 2101 is fixedly connected to the inner wall of the ventilation pipe 11. A ventilation pipe 2102 is fixedly installed on one side of each of the four processing pipes 2101 that is close to each other. An air inlet cover 2103 is provided on the upper surface of each processing pipe 2101 and the upper surface of the ventilation pipe 2102. A support frame 2108 is fixedly installed on the upper surface of each of the four air inlet covers 2103. A gear tube 2106 is fixedly installed on the inner side of each support frame 2108. A ball screw 2107 is rotatably connected to the inner wall of each support frame 2108. A matching nut 2120 is threaded onto the outer surface of each ball screw 2107. Each matching nut 2120 has a fixing plate 2121 fixedly installed on its outer surface. The bottom surface of each fixing plate 2121 is fixedly connected to the upper surface of the air inlet cover 2103. Each ball screw 2107 has a bevel gear 2109 fixedly installed on one end of its outer surface. The outer surfaces of every two bevel gears 2109 mesh with a double gear shaft 2110. The outer surface of each double gear shaft 2110 is rotatably connected to the inner wall of the support frame 2108. Each support frame 2108 has a transmission belt 2111 on its outer side. Each transmission belt 2111 is sleeved on the outer surface of the double gear shaft 2110. Four mounting plates 2104 are fixedly installed on the outer surface of the vent pipe 2102. The outer surface of each mounting plate 2104 is connected to the outer surface of the treatment pipe 2101. The system is fixedly connected, with linear slide rails 2113 fixedly mounted on the upper surfaces of both mounting plates 2104. A slider 2112 is slidably connected to the outer surface of each linear slide rail 2113. The bottom surface of each slider 2112 contacts the upper surface of the mounting plate 2104. A dual-axis independent motor 2105 is fixedly mounted on the outer surface of each slider 2112. One output end of each dual-axis independent motor 2105 is fixedly mounted with a drive gear 2116. Two single-gear shafts 2118 mesh with the outer surface of each drive gear 2116. A support rod 2123 is rotatably connected to the inner wall of each support frame 2108. The outer surface of each support rod 2123 is drively connected to the inner wall of the transmission belt 2111. A transmission gear shaft 2119 is fixedly installed on both the outer surface of the external shaft and the outer surface of the single gear shaft 2118. A lifting gear 2114 is fixedly installed on the other output end of each dual-shaft independent motor 2105. A first lifting rack 2115 meshes with the outer surface of each lifting gear 2114. The upper surface of each first lifting rack 2115 is fixedly connected to the bottom surface of the corresponding air inlet cover 2103. By setting an inlet adjustment unit 21, multiple gas treatment pipes 2101 can be independently controlled, thereby opening different pipes to treat different types of gases. The overall structure can precisely adjust the opening and closing of the corresponding air inlet cover 2103 to achieve gas classification and treatment, effectively avoiding secondary pollution problems that may be caused by the mixed emission of multiple harmful gases.This facilitates the safe discharge of various harmful gases after appropriate treatment, thus optimizing the ventilation process;

[0035] Please see Figure 5 Each dual-shaft independent motor 2105 has a bracket 2117 fixedly installed on its outer surface. The inner wall of each bracket 2117 is rotatably connected to the outer surface of the single gear shaft 2118. Through the bracket 2117, the single gear shaft 2118 can rotate more stably, thereby ensuring that the transmission gear shaft 2119 can stably drive the transmission belt 2111 for transmission, thus improving the stability and reliability of the overall structure.

[0036] Please see Figure 6 Each support frame 2108 has two limiting grooves 2122 on one side near the matching nut 2120. Each limiting groove 2122 is adapted to the fixing plate 2121. The limiting groove 2122 can limit the fixing plate 2121, making the fixing plate 2121 more stable when moving and preventing the fixing plate 2121 from shifting or shaking.

[0037] The specific implementation of this embodiment is as follows: During ventilation, the ventilation fan 12 is turned on, and the ventilation fan 12 extracts gas from a specific location through the ventilation pipe 11. Based on the gas detection technology of the Internet of Things, when different types of gas are detected, the linear slide rail 2113 is activated. The linear slide rail 2113 drives the slider 2112 to move, which in turn drives the dual-axis independent motor 2105 to move. When the transmission gear shafts 2119 are meshed, the linear slide rail 2113 is stopped, and the dual-axis independent motor 2105 is activated. The dual-axis independent motor 2105 drives the drive gear 2116 to rotate, the drive gear 2116 drives the single gear shaft 2118 to rotate, and the single gear shaft 2118 drives the transmission gear shaft 2119 to rotate. The transmission gear shafts 2119 are meshed and drive the dual gear shaft 2110 to rotate through the transmission belt 2111. The dual gear shaft 2110 drives the ball screw 21 through the bevel gear 2109. 07 rotates, the ball screw 2107 drives the matching nut 2120 to move axially, further driving the air inlet cover 2103 to move in a fixed direction. To avoid the air inlet cover 2103 obstructing the treatment pipe 2101, the linear slide rail 2113 can be activated to move the transmission gear shaft 2119 into the gear tube 2106. Through the transmission gear shaft 2119 driving the gear tube 2106, the air inlet cover 2103 can be rotated as a whole. When it is necessary to open the vent pipe 2102, only the other shaft of the dual-shaft independent motor 2105 needs to be activated to drive the lifting gear 2114 to rotate. The lifting gear 2114 meshes with the first lifting rack 2115, thereby driving the first lifting rack 2115 to move up and down, driving the air inlet cover 2103 to move up and down synchronously. The whole system can be opened and closed independently when a specific treatment pipe 2101 needs to be opened to meet the treatment needs of different gases.

[0038] Example 2: Please refer to Figures 1-3 and Figures 7-9 The present invention provides a technical solution: a ventilation outlet adjustment device based on the Internet of Things. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The ventilation outlet adjustment mechanism 2 also includes an outlet synchronization unit 22, which is located inside the ventilation pipe 11. The outlet synchronization unit 22 can be opened and closed synchronously with the inlet adjustment unit 21 for synchronous gas discharge.

[0039] As a further definition of the air outlet adjustment mechanism 2 of the present invention, the outlet synchronization unit 22 includes four driven gears 2203. The inner wall of each driven gear 2203 is fixedly connected to the outer surface of a single gear shaft 2118. A matching gear shaft 2204 is provided below each driven gear 2203. A single grooved wheel 2217 is fixedly installed on the outer surface of each matching gear shaft 2204. A first synchronous belt 2205 is drivenly connected to the outer surface of each single grooved wheel 2217. An intermediate pulley 2206 is drivenly connected to the inner ring of each first synchronous belt 2205. An intermediate pulley 2206 is drivenly connected to the outer surface of each intermediate pulley 2206. Each short synchronous belt 2207 has a second synchronous belt 2211 on its outer side. Each second synchronous belt 2211 is located inside the processing tube 2101. The inner ring of each second synchronous belt 2211 is drivenly connected to two double-grooved pulleys 2209. The inner ring of each short synchronous belt 2207 is drivenly connected to the outer surface of the double-grooved pulleys 2209. A lifting screw 2202 is fixedly installed on the inner wall of each double-grooved pulley 2209. A bearing plate 2208 is drivenly connected to the outer surface of each lifting screw 2202. Each bearing plate 2208 is fixedly installed on the inner wall of the processing tube 2101. The outer surface of the lifting screw 2202 is threaded with lifting blocks 2210. Each lifting block 2210 has a telescopic push rod 2213 fixedly installed on its inner wall. Each telescopic push rod 2213 has a fixed angle plate 2212 fixedly installed at its telescopic end. Each processing pipe 2101 and the vent pipe 2102 are equipped with an exhaust cover 2201. Support shafts 2214 are fixedly installed on the inner walls of four exhaust covers 2201. The outer surface of each support shaft 2214 is rotatably connected to the inner wall of the processing pipe 2101. The bottom surface of each fixed angle plate 2212 is fixedly connected to the upper surface of the exhaust cover 2201. Next, the outer surface of each lifting gear 2114 is meshed with a second lifting rack 2216, and the bottom surface of each second lifting rack 2216 is fixedly connected to the upper surface of one of the exhaust covers 2201. By setting an outlet synchronization unit 22, the inlet adjustment unit 21 and the outlet synchronization unit 22 can be precisely synchronized. The inlet cover 2103 and the exhaust cover 2201 open synchronously to ensure synchronous gas discharge and prevent harmful gases from entering other treatment pipes 2101 when a single treatment pipe 2101 is open. This ensures that the emission of harmful gases is in a single pipe to prevent mixing between gas emissions.

[0040] Please see Figure 9 Four support rails 2215 are fixedly installed on the inner wall of the vent pipe 2102. The interior of each first lifting rack 2115 and the interior of each second lifting rack 2216 are slidably connected to the outer surface of the support rail 2215. Through the support rails 2215, the first lifting rack 2115 and the second lifting rack 2216 can slide more stably, thereby ensuring the stable opening and closing of the exhaust cover 2201.

[0041] The specific implementation of this embodiment is as follows: When the air intake cover 2103 opens, as the dual-shaft independent motor 2105 moves, the driven gear 2203 meshes with the matching gear shaft 2204 at a designated position. As the single gear shaft 2118 rotates, it drives the driven gear 2203 to rotate. The driven gear 2203 further drives the matching gear shaft 2204 to rotate. The matching gear shaft 2204 drives the intermediate pulley 2206 to rotate via the first synchronous belt 2205. The intermediate pulley 2206 then drives the double-grooved pulley 2209 to rotate via the short synchronous belt 2207. The double-grooved pulley 2209 drives the lifting screw 2202. When rotated, the lifting block 2210 moves along the axial direction of the lifting screw 2202. During the descent of the lifting block 2210, the telescopic push rod 2213 is activated. The telescopic end of the telescopic push rod 2213 pushes the fixed angle plate 2212, thereby driving the exhaust cover 2201 to rotate and open around the support shaft 2214. Similarly, when the vent pipe 2102 is opened, the rotation of the lifting gear 2114 not only drives the air intake cover 2103 to rise and fall, but also drives the second lifting rack 2216 to descend along the support guide rail 2215 through interaction with the second lifting rack 2216, further ensuring the stable opening and closing of the exhaust cover 2201.
