Description

Technical Field

[0001] This utility model relates to the field of controller technology, specifically a wireless single-channel IoT intelligent controller. Background Technology

[0002] With the popularization of IoT terminal devices, wireless single-channel IoT smart controllers are becoming core components in scenarios such as single-device control in smart homes, single-point monitoring in industries, and single-actuator drive in smart agriculture. Their application demand continues to grow. Although this type of controller is designed for a single control loop, it still integrates a single-channel control module, a wireless communication module, a power supply and voltage regulation module, and a status detection module. In actual use, each module will generate heat during continuous operation. The heat generation is particularly prominent in the wireless communication module when transmitting and receiving data, the power supply module when regulating and converting voltage, and the single-channel control module when switching on and off at high frequencies. Moreover, due to the compact size of the single-channel controller, internal heat is prone to accumulate quickly.

[0003] The heat dissipation method of existing wireless single-channel IoT smart controllers is still mainly passive heat dissipation. Usually, a few heat dissipation holes are opened on the side wall of the housing, or small metal heat sinks are attached to the surface of the core heat-generating modules, such as relays. However, the miniaturized housing structure of single-channel controllers has a small number of heat dissipation holes with small diameters, resulting in low air convection efficiency and an inability to quickly remove the heat accumulated inside. In addition, it is difficult to prevent external dust from entering the controller during use. Utility Model Content

[0004] The purpose of this invention is to provide a wireless single-channel IoT intelligent controller with the advantages of efficient heat dissipation and preventing external dust from entering the controller during use, thus solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wireless single-channel IoT smart controller includes a controller housing, a fixing plate fixed to the lower end of the controller housing, a dustproof box fixed to the lower end of the fixing plate, a mounting plate fixed to the inner wall of the upper end of the controller housing, a cylindrical groove through the upper end of the mounting plate, a rotating body slidably disposed on the inner wall of the cylindrical groove, a first fixing ring fixed to the upper part of the side wall of the rotating body, a protrusion fixed to the side wall of the first fixing ring, a blocking mechanism fixed to the upper end of the mounting plate to prevent the protrusion from moving, a central column fixed to the center of the upper end of the fixing plate, a sleeve rotatably mounted on the side wall of the central column, at least three connecting blocks fixed to the side wall of the sleeve, and multiple second fixing rings disposed inside the controller housing. The controller housing is frame-shaped, and a control panel is provided on the upper end of the rotating body.

[0007] Multiple second fixing rings are evenly distributed along the circumference of the sleeve. Two adjacent second fixing rings are directly fixed to each other through their side walls to form a continuous ring structure. The line connecting the midpoints of the multiple second fixing rings is located on the circumference of the same circle. The end of the connecting block away from the sleeve is fixed to the side wall of the second fixing ring.

[0008] A turntable is rotatably mounted on the inner wall of the second fixed ring. A control mechanism is mounted on the turntable. The control mechanism and the control panel are electrically connected by wires. At least two threaded posts are threadedly mounted on the upper end of the rotating body. The lower ends of the threaded posts pass through the rotating body and are threadedly mounted in the wall layer of the sleeve.

[0009] Two cooling fans are fixedly connected through the upper part of the mounting plate, and a dustproof mechanism is provided on the dustproof box.

[0010] Preferably, the blocking mechanism includes a first block and a second block fixed to the upper end of the mounting plate. The ends of the first block and the second block near the center of the rotating body are both in contact with the side wall of the first fixed ring. The line connecting the center of the first block, the second block and the rotating body forms an acute triangle.

[0011] It is worth noting that the fitted design of the first stop, the second stop, and the first fixed ring can prevent the rotating body from radially moving within the cylindrical groove, ensuring the coaxiality and stability of the rotating body during rotation. The rotating body can drive the control panel at the upper end and related components such as sleeves and connecting blocks to rotate slightly. This rotation can change the airflow direction inside the controller. Areas that are prone to forming airflow dead zones can be adjusted by rotating the relative positions of the components, so that the airflow generated by the cooling fan can more evenly cover each electronic module, avoiding local heat accumulation and improving heat dissipation efficiency.

[0012] Preferably, the control mechanism includes a main control chip, a wireless communication module, a relay, a power management module, a storage module, an encryption module, an edge computing module, a lithium battery, and a voice interaction module, with each of the wireless communication module, relay, power management module, storage module, encryption module, edge computing module, lithium battery, and voice interaction module fixedly mounted on a single turntable.

[0013] It is worth noting that the control mechanism adopts a modular design, with the main control chip, wireless communication module, relay, power management module, storage module, encryption module, edge computing module, lithium battery, and voice interaction module each fixed on a single turntable. The modular layout makes each functional module independent, allowing for individual disassembly, repair, or replacement of a single faulty module without disassembling the entire control mechanism. This significantly reduces maintenance difficulty and costs, while also shortening maintenance time. In addition, the distributed installation of each module effectively reduces electromagnetic interference between modules, preventing electromagnetic signals generated by different modules from affecting each other during operation and improving the stability of each module's operation.

[0014] Preferably, there is a gap between the side wall of the second fixing ring and the inner wall of the controller housing.

[0015] It is worth noting that the gap can form an independent ventilation channel. Together with the cooling fan on the mounting plate, it can guide the airflow to flow smoothly inside the controller housing, quickly remove the heat generated by the second mounting ring and the electronic modules on the turntable during operation, and prevent heat from accumulating in local areas and causing the temperature to be too high.

[0016] Preferably, there is a gap between the lower end of the second fixing ring and the upper end of the fixing plate.

[0017] It is worth noting that a gap is reserved between the lower end of the second fixing ring and the upper end of the fixing plate, which can effectively avoid mechanical interference between the second fixing ring and the fixing plate.

[0018] Preferably, the side walls of the controller housing, mounting plate, and dustproof box are all flush.

[0019] It is worth noting that the flush sidewalls give the controller a neat and simple overall appearance, enhancing the aesthetics of the device.

[0020] Preferably, the dustproof mechanism includes a vertical plate, a baffle, a filter cotton plate, a first ventilation slot, and a first filter screen. The upper end of the dustproof box is open, and two vertical plates are fixedly connected to the inner wall of the lower end of the dustproof box. A baffle is fixedly connected to the upper end of each of the two vertical plates. A filter cotton plate is placed between the two vertical plates, with the upper end of the filter cotton plate and the lower end of the baffle fitting together. A first ventilation slot is provided through the lower end of the dustproof box, located directly below the filter cotton plate. A first filter screen is fixedly connected to the inner wall of the first ventilation slot, and the filter cotton plate is located directly below the two cooling fans.

[0021] It is worth noting that the dual filtration structure, consisting of a filter cotton plate and a first filter screen, effectively filters larger dust particles and impurities in the air. The first filter screen further filters fine dust, and the dual filtration significantly improves the dustproof effect, preventing external dust from entering the controller and contaminating the electronic modules. The filter cotton plate is positioned by a vertical plate and a baffle, and fits snugly against the lower end of the baffle, making it easy for staff to quickly disassemble and replace the filter cotton plate, reducing the maintenance difficulty of the dustproof components. The filter cotton plate is located directly below the cooling fan, ensuring that all air drawn in by the cooling fan is filtered, thus ensuring air intake efficiency while preventing unfiltered air from directly entering the controller.

[0022] Preferably, the dustproof mechanism consists of a second ventilation slot, a second filter, a first fixing frame, a third filter, a second fixing frame, and a fourth filter. The lower end of the dustproof box has a second ventilation slot through which the second filter is fixedly connected. The inner wall of the second ventilation slot is fixedly connected to the second filter. The bottom surface of the inner wall of the dustproof box is fixedly connected to the first fixing frame and the third filter. The inner wall of the first fixing frame is fixedly connected to the second fixing frame. The inner wall of the third filter is fixedly connected to the fourth filter. The area enclosed by the third filter and the inner wall of the dustproof box is located below the cooling fan.

[0023] It is worth noting that the multi-layered filtration structure consisting of the second, third, and fourth filters can progressively filter impurities of different particle sizes in the air, resulting in higher filtration accuracy and more thorough dust prevention. It can effectively prevent fine dust from entering the controller. In addition, the area enclosed by the third filter and the inner wall of the dust box is located below the cooling fan, allowing air to pass through multiple filters before flowing out of the dust box.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1. This utility model uses two cooling fans that are fixedly connected through the upper end of the fixed plate. At the same time, a gap is reserved between the side wall of the second fixed ring and the inner wall of the controller housing to form an independent ventilation channel. A gap is also reserved between the lower end of the second fixed ring and the upper end of the fixed plate to avoid mechanical interference and assist the airflow to sink. When working, the cooling fans actively run to form a directional airflow. The airflow can flow smoothly along the path of the dust box, the reserved ventilation channel, the internal space of the controller and the gap of the housing, and directly act on the surface of all electronic modules. It replaces the traditional passive heat dissipation method, significantly improves the air convection efficiency, and can quickly remove the concentrated heat generated when the wireless communication module transmits and receives data, when the power management module regulates and converts voltage, and when the relay switches on and off at high frequency. It solves the technical problem of rapid accumulation of internal heat and inability to dissipate it in time.

[0026] 2. This utility model adopts a modular design for the control mechanism, fixing the wireless communication module, power management module, relays, etc. on independent turntables. Each turntable is installed in a second fixed ring evenly distributed along the circumference of the sleeve. The dispersed layout avoids the accumulation of heat generated by the modules. On the other hand, the rotating body can slide and rotate along the cylindrical groove of the mounting plate. When rotating, it drives the first fixed ring and the protrusion at the upper end to rotate synchronously. The first stop and the second stop restrict the radial movement of the rotating body and ensure the coaxiality of the rotation by fitting with the first fixed ring. At the same time, the rotating body is fixed to the sleeve through the threaded column, which can drive the sleeve, connecting block, second fixed ring and turntable to rotate slightly, dynamically changing the airflow direction inside the controller, eliminating the airflow dead corners under the traditional fixed layout, and making the airflow generated by the cooling fan evenly cover all modules, including the wireless communication module and power management module that were not covered before. This effectively solves the technical problem of long-term high temperature of secondary modules.

[0027] 3. This utility model, by setting a dustproof mechanism inside the dustproof box, with all filter components of the dustproof mechanism located directly below the cooling fan, ensures that all air drawn in by the cooling fan is filtered. The dustproof mechanism can adopt a dual filtration structure consisting of a filter cotton plate and a first filter screen, where the filter cotton plate blocks larger dust particles and the first filter screen intercepts fine dust. Alternatively, it can adopt a multi-layer filtration structure consisting of a second, third, and fourth filter screen to progressively filter impurities of different particle sizes, significantly improving the dustproof effect. This not only prevents external dust from entering the controller and contaminating the electronic modules, but also does not obstruct airflow, achieving a balance between heat dissipation and protection performance.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] To address the issue of poor heat dissipation in existing wireless single-channel IoT smart controllers, which makes it difficult to prevent external dust from entering the controller during use, the following technical solution is provided. Please refer to [link / reference]. Figures 1-8 ;

[0039] A wireless single-channel IoT smart controller includes a controller housing 1, a fixing plate 2 fixed to the lower end of the controller housing 1, a dustproof box 3 fixed to the lower end of the fixing plate 2, a mounting plate 4 fixed to the inner wall of the upper end of the controller housing 1, a cylindrical groove through the upper end of the mounting plate 4, a rotating body 5 slidably disposed on the inner wall of the cylindrical groove, a first fixing ring 6 fixed to the upper part of the side wall of the rotating body 5, a protrusion 7 fixed to the side wall of the first fixing ring 6, a blocking mechanism fixed to the upper end of the mounting plate 4 to prevent the protrusion 7 from moving, a central column 10 fixed to the center of the upper end of the fixing plate 2, a sleeve 11 rotatably mounted on the side wall of the central column 10, at least three connecting blocks 12 fixed to the side wall of the sleeve 11, and multiple second fixing rings 13 disposed inside the controller housing 1. The controller housing 1 is frame-shaped, and a control panel is provided on the upper end of the rotating body 5.

[0040] Multiple second fixing rings 13 are evenly distributed along the circumference of the sleeve 11. Two adjacent second fixing rings 13 are directly fixed to each other through their side walls to form a continuous ring structure. The line connecting the midpoints of the multiple second fixing rings 13 is located on the circumference of the same circle. The end of the connecting block 12 away from the sleeve 11 is fixed to the side wall of the second fixing ring 13.

[0041] A turntable 14 is rotatably mounted on the inner wall of the second fixed ring 13. A control mechanism is mounted on the turntable 14. The control mechanism and the control panel are electrically connected by wires. At least two threaded posts 15 are threadedly mounted on the upper end of the rotating body 5. The lower ends of the threaded posts 15 pass through the rotating body 5 and are threadedly mounted in the wall layer of the sleeve 11.

[0042] Two cooling fans 16 are fixedly connected through the upper end of the fixed plate 2, and a dustproof mechanism is provided on the dustproof box 3.

[0043] In use, since the lower end of the threaded column 15 passes through the rotating body 5 and is threaded into the wall of the sleeve 11, the sleeve 11 and the rotating body 5 will rotate synchronously. The blocking mechanism blocks the protrusion 7, so the rotating body 5 can rotate slightly along the inner wall of the cylindrical groove within a certain angle, thereby adjusting the position of the control mechanism relative to the controller housing 1. Opening the threaded column 15 can draw the heat inside the controller housing 1 into the dust box 3 and discharge it to the outside through the dustproof mechanism.

[0044] In this embodiment, specifically: the blocking mechanism includes a first block 8 and a second block 9 fixed to the upper end of the mounting plate 4. The ends of the first block 8 and the second block 9 near the center of the rotating body 5 are both in contact with the side wall of the first fixed ring 6. The line connecting the center of the first block 8, the second block 9 and the rotating body 5 forms an acute triangle.

[0045] In this embodiment, the control mechanism specifically includes a main control chip, a wireless communication module, a relay, a power management module, a storage module, an encryption module, an edge computing module, a lithium battery, and a voice interaction module. The wireless communication module, relay, power management module, storage module, encryption module, edge computing module, lithium battery, and voice interaction module are respectively fixed on a single turntable 14.

[0046] In this embodiment, specifically, there is a gap between the side wall of the second fixing ring 13 and the inner wall of the controller housing 1.

[0047] In this embodiment, specifically: there is a gap between the lower end of the second fixing ring 13 and the upper end of the fixing plate 2.

[0048] In this embodiment, specifically: the side walls of the controller housing 1, the fixing plate 2, and the dustproof box 3 are all flush.

[0049] Example 1: In this example, the dustproof mechanism includes a vertical plate 301, a baffle 302, a filter cotton plate 303, a first ventilation slot 304, and a first filter screen 305. The upper end of the dustproof box 3 is open. Two vertical plates 301 are fixed to the inner wall of the lower end of the dustproof box 3. A baffle 302 is fixed to the upper end of each of the two vertical plates 301. A filter cotton plate 303 is placed between the two vertical plates 301. The upper end of the filter cotton plate 303 is attached to the lower end of the baffle 302. A first ventilation slot 304 is opened through the lower end of the dustproof box 3. The first ventilation slot 304 is located directly below the filter cotton plate 303. A first filter screen 305 is fixed to the inner wall of the first ventilation slot 304. The filter cotton plate 303 is located directly below the two cooling fans 16.

[0050] This design achieves dual filtration through the filter cotton plate 303 and the first filter screen 305, which can effectively block larger particles and fine dust from entering the controller, thus improving the dustproof effect. The structure of the upright plate 301 and the baffle 302 makes the filter cotton plate 303 easy to place and replace, reducing the maintenance difficulty. The filter cotton plate 303 is located directly below the cooling fan 16, ensuring that all incoming air is filtered, which can prevent dust accumulation while ensuring heat dissipation efficiency.

[0051] Example 2: In this example, the dustproof mechanism consists of a second ventilation slot 306, a second filter screen 307, a first fixing frame 308, a third filter screen 309, a second fixing frame 310, and a fourth filter screen 311. The lower end of the dustproof box 3 has a through-hole of the second ventilation slot 306. The second filter screen 307 is fixed to the inner wall of the second ventilation slot 306. The first fixing frame 308 and the third filter screen 309 are fixed to the bottom surface of the inner wall of the dustproof box 3. The second fixing frame 310 is fixed to the inner wall of the first fixing frame 308. The fourth filter screen 311 is fixed to the inner wall of the third filter screen 309. The area enclosed by the third filter screen 309 and the inner wall of the dustproof box 3 is located below the cooling fan 16.

[0052] The design employs a multi-layered filtration structure consisting of a second filter 307, a third filter 309, and a fourth filter 311. This structure can progressively filter impurities of different particle sizes, improving filtration accuracy and dustproof performance. The first fixed frame 308 and the second fixed frame 310 provide stable support, ensuring the filter is firmly positioned. The area enclosed by the third filter 309 is located below the cooling fan 16, guiding air through multiple filtration processes before it is drawn in, thus enhancing dustproof reliability.

[0053] It should be noted that two cooling fans 16 are provided, and in use, the exhaust ends of the two cooling fans 16 can be opposite to each other.

[0054] Working principle: First, the whole is fixed by the fixing plate 2. The operator initiates the operation through the control panel on the upper end of the rotating body 5. If it is necessary to adjust the position of the control mechanism relative to the controller housing 1, the control panel is rotated to drive the rotating body 5 to rotate along the inner wall of the cylindrical groove of the mounting plate 4. Since the lower end of the threaded column 15 passes through the rotating body 5 and is threadedly installed in the wall of the sleeve 11, the rotating body 5 drives the sleeve 11 to rotate around the central column 10. The sleeve 11 drives the second fixing ring 13, the turntable 14 and the control mechanism on the turntable 14 to rotate together through the connecting block 12 until the protrusion 7 on the side wall of the first fixing ring 6 contacts the first stop block 8 or the second stop block 9. The rotating body 5 stops rotating, and the position of the control mechanism is adjusted slightly.

[0055] Two cooling fans 16 with opposite air outlets are activated for heat dissipation. If the dustproof mechanism of Embodiment 1 is used, air enters from the first ventilation slot 304 at the lower end of the dustproof box 3, is initially filtered by the first filter screen 305, and then is filtered a second time by the filter cotton plate 303 between the two vertical plates 301. The clean air is drawn into the controller housing 1 by the cooling fan 16, flows through the gap between the second fixing ring 13 and the inner wall of the controller housing 1 and the upper end of the fixing plate 2, exchanges heat with the control mechanism, and is then discharged.

[0056] If the dustproof mechanism of Embodiment 2 is adopted, air enters from the second ventilation slot 306 at the lower end of the dustproof box 3, and after being initially filtered by the second filter screen 307, it enters the area enclosed by the third filter screen 309 and the inner wall of the dustproof box 3. This area is located below the cooling fan 16, and after being filtered a second time by the third filter screen 309 and the fourth filter screen 311, the clean air is drawn in by the cooling fan 16 and discharged after completing heat exchange. The first fixed frame 308 and the second fixed frame 310 provide support for the relevant components.

[0057] During control execution, the control panel transmits instructions to the main control chip of the control mechanism via wires. The main control chip combines the data from the storage module with the data from the edge computing module. After processing, the chip controls the wireless communication module to achieve wireless data interaction with external devices, controls the relay to perform switching actions to control external loads, the power management module manages the lithium battery to supply power to various components, the encryption module encrypts the transmitted data, and the voice interaction module enables voice command reception and feedback. At the same time, the turntable 14 can rotate on the inner wall of the second fixed ring 13 to adjust the orientation of each module of the control mechanism, ultimately realizing the wireless single-channel IoT intelligent control function.

[0058] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
