Description

Technical Field

This residual moisture is not easily detected and is difficult to completely drain through passive drainage holes. Over time, it may cause corrosion of internal components or even short circuits, thus seriously affecting the performance and lifespan of the equipment. Utility Model Content

[0049] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] like Figures 1 to 3 As shown, an embodiment of this utility model provides a central control device, which includes: a housing 10, a control component, and a vibrating element 20. The housing 10 has a mounting cavity 11, a flow guide 12 located within the mounting cavity 11, and a drain hole 13 penetrating the inside and outside of the mounting cavity 11. The control component is installed within the mounting cavity 11. The flow guide 12 has a flow inlet end 121 and a flow outlet end 122. The drain hole 13 is located at or below the flow outlet end 122. Along the extension direction from the flow inlet end 121 to the flow outlet end 122, the flow guide height of the flow guide 12 gradually decreases. The vibrating element 20 is installed on the housing 10 and located within the mounting cavity 11. The vibrating element 20 has an open state and a closed state. When the vibrating element 20 is in the open state, it is vibrating. When the vibrating element 20 is in the closed state, it stops vibrating.

[0051] The central control device provided in this embodiment utilizes the gradually decreasing guide height of the guide section 12 and the vibration of the vibrating element 20. These two elements work synergistically to accelerate the flow of water inside the central control device along the guide section 12 to the drain hole 13, thereby achieving active drainage. The implementation effect is significant, greatly improving liquid drainage efficiency and effectively avoiding the risks of internal corrosion and short circuits. Application scenarios in this embodiment include industrial automation control, smart home systems, and outdoor electronic devices, and it is particularly suitable for use in environments with high humidity or those susceptible to liquid splashes. The process involves automatically activating the vibrating element 20 when the device detects internal liquid, accelerating liquid drainage through vibration and ensuring the device's interior remains dry. Therefore, the central control device provided in this embodiment solves the technical problem in existing central control devices where residual moisture can affect the performance and lifespan of internal components.

[0052] It should be noted that water can drip directly onto any location of the guide section 12, not limited to the guide inlet 121 and the guide outlet 122. The control components include, but are not limited to, circuit boards, electronic devices, and connecting lines.

[0053] Specifically, a vibrating element 20 is provided at the outlet end 122. The principle of providing the vibrating element 20 at the outlet end 122 is to further accelerate the discharge of liquid through the local high-frequency vibration of the vibrating element 20, so as to ensure that the liquid does not stagnate at the end of the guide section 12.

[0054] Specifically, along the extension direction from the inlet end 121 to the outlet end 122, the guide section 12 is inclined at an angle α with the horizontal direction, where 5°≤α≤30°. The inclined design principle of the guide section 12 is to utilize gravity to allow the liquid to flow naturally to the drain hole 13, reducing the residence time of the liquid inside the equipment. The effect is more thorough liquid discharge and stronger equipment protection. Application scenarios include environments that require frequent cleaning or may be subject to liquid splashes, such as food processing workshops and laboratory equipment. In operation, when the equipment detects liquid inside, the vibrator 20 is activated, and the liquid is quickly discharged under the combined action of the inclination and vibration of the guide section 12.

[0055] Specifically, the guide section 12 is provided with a guide channel so that the water inside can be concentrated and guided out through the guide channel.

[0056] Specifically, there are multiple vibrating elements 20, which are spaced apart on the outer casing 10 and all located within the mounting cavity 11. At least one of the vibrating elements 20 is located at the flow outlet 122. Through the coordinated operation of multiple vibrating elements 20, the liquid inside the equipment is comprehensively and acceleratedly discharged. In particular, the location of at least one vibrating element 20 at the flow outlet 122 effectively prevents liquid stagnation at the outlet. The effect is improved efficiency and thoroughness of liquid discharge, enhancing the protective performance of the equipment. Application scenarios include equipment requiring multi-directional protection, not limited to outdoor surveillance cameras and mobile electronic devices in different usage environments. In operation, when liquid is detected inside the central control equipment, all vibrating elements 20 can be activated synchronously to accelerate liquid discharge through high-frequency vibration, ensuring the dryness and safety of the equipment's interior.

[0057] Specifically, the guide section 12 is located at the bottom of the mounting cavity 11. In this way, gravity can be used to allow the liquid to flow naturally to the lowest point, making it easier to discharge.

[0058] Specifically, there are two guide outlets 122, located at opposite ends of the guide section 12, with the guide inlet 121 situated between the two guide outlets 122. This structural arrangement increases drainage points, improving the efficiency and uniformity of liquid discharge and preventing liquid accumulation at a single outlet. The result is faster and more uniform liquid discharge, and improved equipment protection. Applications include large industrial equipment and smart home control centers, particularly for equipment with large internal spaces where liquid may accumulate in different locations. In operation, when the equipment detects internal liquid, the vibrator 20 activates, guiding the liquid through the guide section 12 to flow rapidly towards and discharge the two guide outlets 122, ensuring the dryness and safety of the equipment's interior.

[0059] In this embodiment, the outer casing 10 includes a main body 14 and a mounting step 15. A flow guide 12 is disposed on the main body 14. The mounting step 15 is disposed on the main body 14 and located at the flow outlet end 122. The mounting step 15 is positioned higher than the flow outlet end 122, and the vibrator 20 is mounted on the mounting step 15. The mounting step 15 provides a stable mounting position for the vibrator 20, preventing damage or reduced lifespan due to prolonged immersion in water. Simultaneously, the height difference further enhances the efficiency of liquid drainage. The result is more stable operation of the vibrator 20, more thorough liquid drainage, and stronger equipment protection. Application scenarios include equipment requiring enhanced protection in specific locations, such as kitchen appliances and bathroom electronic devices, especially areas susceptible to liquid splashes. In operation, when the equipment detects internal liquid, the vibrator 20, supported by the stable mounting step 15, activates, accelerating liquid drainage through high-frequency vibration to ensure the dryness and safety of the equipment's interior.

[0060] Specifically, the main body 14 includes a base plate 141 and an annular shell 142 connected to each other, with the annular shell 142 surrounding the periphery of the base plate 141. In this way, the structure of the annular shell 142 provides a water guiding path for the flow guide 12 to surround the device.

[0061] The guide section 12 is located at the bottom of the inner ring of the annular shell 142 to facilitate drainage by gravity.

[0062] Alternatively, the inlet end 121 of the guide section 12 is located on the base plate 141, and the outlet end 122 of the guide section 12 is connected to the annular shell 142. The connection between the base plate 141 and the annular shell 142 forms a drainage channel from the center to the edge, facilitating better drainage of water from the base plate 141 to the drain hole 13 via the guide section 12. This configuration improves the equipment's protection level, ensures smoother liquid drainage, and reduces liquid residue inside the equipment. Application scenarios include equipment requiring all-around protection, such as outdoor electronic devices and smart home control centers, especially those potentially subject to multi-directional liquid splashes. During operation, when the equipment detects internal liquid, the vibrator 20 activates. Guided by the guide section 12, the liquid quickly flows to and is discharged through the drain hole 13 of the annular shell 142, or flows from the base plate 141 to the drain hole 13 of the annular shell 142, ensuring the dryness and safety of the equipment's interior. Specifically, multiple flow guiding structures can be configured, and these multiple flow guiding structures are distributed radially, extending from the center of the central control device to the drainage hole 13 at the edge.

[0063] Specifically, the central control equipment also includes a check valve, which is located at the drain hole 13. The check valve works by using a one-way valve structure to prevent external liquids and dust from flowing back into the mounting cavity 11, thus protecting the cleanliness and dryness of the equipment's interior.

[0064] In this embodiment, the vibration frequency of the vibrating element 20 is 50Hz. This effectively ensures the active discharge of water while avoiding the impact of excessively high vibration frequency on the installation stability and stable operation of the central control equipment's internal structure, thus guaranteeing the stable operation and service life of the central control equipment.

[0065] Specifically, the central control equipment also includes a hydrophobic coating made of superhydrophobic material. This coating is applied to the drain hole 13 and / or the guide section 12. The principle of the hydrophobic coating is to utilize the properties of superhydrophobic materials to reduce liquid adhesion to the surface and accelerate liquid drainage. The effect is improved equipment protection, reduced maintenance costs, and extended equipment lifespan. Application scenarios include equipment used in harsh environments, such as control equipment in chemical plants and outdoor advertising displays, especially those susceptible to liquid splashes and dust intrusion. In operation, when liquid is detected inside the equipment, the vibrator 20 activates. Guided by the guide section 12, the liquid quickly flows to the drain hole 13 and is discharged. The check valve and the hydrophobic coating work together to prevent liquid and dust backflow, ensuring the dryness and safety of the equipment's interior.

[0066] In this embodiment, the central control device also includes a detection element 30, which is disposed within the mounting cavity 11. The detection element 30 is used to detect whether liquid is generated within the mounting cavity 11. By detecting whether liquid is generated inside the central control device, the intelligent protection capability of the device can be improved, enabling it to respond to the liquid generation situation in a timely manner and activate corresponding protective measures. Application scenarios include central control devices requiring intelligent protection, such as smart refrigerators and smart washing machines, especially those devices that may generate liquid inside.

[0067] Specifically, the central control device also includes a control module, which is electrically connected to the detection element 30. In operation, when the detection element 30 detects liquid inside the central control device, it immediately sends a signal to the control module. The control module then activates the vibrating element 20 based on the signal, accelerating the discharge of the liquid and ensuring the dryness and safety of the equipment's interior.

[0068] Specifically, the detection component 30 can be a sensor, which can be a liquid level sensor, to detect whether liquid is generated inside the central control equipment.

[0069] Specifically, the central control device also includes a display unit and a control module. The display unit is connected to the detection element 30 and displays the information detected by the detection element 30. The control module is connected to the vibrating element 20 and is configured to control the vibrating element 20 based on user operation information. This configuration facilitates user operation when the display unit shows that water has been detected, improving operational convenience. Specifically, the display unit also has a prompting function, possessing a light-emitting or sound-emitting part to provide prompts. Specifically, the display unit is connected to the detection element 30, and the control module is connected to the vibrating element 20; this connection can be understood as an electrical connection or a signal connection.

[0070] Alternatively, the central control device may also include a control module. Both the detection element 30 and the vibrating element 20 are connected to the control module. The control module is configured to: when the detection element 30 detects the generation of liquid, control the vibrating element 20 to be in the on state and run for a preset time; or, control the vibrating element 20 to intermittently enter the on state. In this way, through the intelligent control of the control module, precise control of the vibrating element 20 is achieved, and the working mode of the vibrating element 20 can be flexibly adjusted according to the actual situation of liquid generation.

[0071] Alternatively, the central control device may also include a control module, with the detection element 30 and control components all connected to the control module. The control module is configured to: when the detection element 30 detects the generation of liquid, control the control component to operate and raise its operating temperature to a preset temperature to heat the liquid in the mounting cavity 11; or, the central control device may include a heating unit, which is activated by the control component to increase the temperature when the detection element 30 detects the generation of liquid. The principle of this design is to achieve precise control of the vibrating element 20 through intelligent control of the control module. It can flexibly adjust the operating mode of the vibrating element 20 according to the actual situation of liquid generation, and simultaneously accelerate liquid evaporation through the heating function, further improving the equipment's protective capabilities. The implementation effect is to improve the equipment's intelligence level, enhance its protective performance, reduce maintenance costs, and extend its service life. Application scenarios include equipment requiring intelligent protection and maintenance, such as control equipment in smart factories and smart home systems, especially those that may be subject to liquid splashes and require regular maintenance. The process is as follows: when the detection element 30 detects liquid generated inside the equipment, the control module starts the vibration element 20 according to the preset control strategy to accelerate the discharge of liquid. At the same time, the heating function is activated as needed to accelerate the evaporation of liquid, ensuring the dryness and safety of the equipment.

[0072] Specifically, "when the detection component 30 detects the generation of liquid, it controls the operation of the control component and makes the operating temperature of the control component reach the preset temperature to heat the liquid in the mounting cavity 11" can be understood as using a program to increase the computational load of the chip in the control component to reach the preset temperature.

[0073] Specifically, the preset temperature can be 40℃.

[0074] In this embodiment, the detection element 30 is a capacitive or resistive sensor. The principle of a capacitive or resistive sensor is to detect whether liquid is generated inside the device by utilizing changes in capacitance or resistance. The effect is improved detection sensitivity and accuracy, enabling immediate response to liquid splashing events and the activation of protective measures. Application scenarios include devices requiring high-precision liquid detection, such as intelligent medical devices and precision electronic equipment, especially those devices that may generate trace amounts of liquid internally. The process involves the capacitive or resistive sensor immediately detecting the change when liquid is generated inside the device and sending a signal to the control module. The control module then activates the vibrating element 20 based on the signal, accelerating the discharge of liquid and ensuring the dryness and safety of the device's interior.

[0075] Specifically, in this embodiment, the angle of the guide channel can be set in the range of 5° to 30°. Preferably, the angle of the guide channel can be set to 5°. Multiple micro vibration motors (frequency 50Hz) can be distributed inside the guide channel or at its periphery. When liquid splashes, the vibration motors are automatically triggered, and the centrifugal force generated by the high-frequency vibration accelerates the liquid to flow along the guide channel toward the drain hole 13.

[0076] Specifically, by integrating a liquid sensor (such as a capacitive or resistive sensor), the vibration mode is activated within 0.5 seconds after liquid is detected. Specifically, the vibrating element 20 in this embodiment may have a delayed shutdown function (such as stopping after 10 seconds of continuous vibration) to ensure that residual liquid is completely discharged.

[0077] Specifically, a hydrophobic coating or a one-way valve structure can be embedded in the drain hole 13 to prevent external liquid backflow and dust intrusion.

[0078] Specifically, the surfaces of the guide portion 12 and / or the drain hole 13 are made of superhydrophobic material (contact angle of superhydrophobic material >150°) to reduce liquid adhesion.

[0079] Specifically, the vibrating element 20 can be a miniature vibration motor (the diameter of the miniature vibration motor is ≤5mm), and multiple vibrating elements 20 can be arranged in a grid pattern in the groove to ensure that the vibration coverage is complete without any dead angles.

[0080] The vibration control logic in this embodiment includes: after the sensor signal triggers, the vibration motor works intermittently at a frequency of 50Hz (e.g., vibrate for 2 seconds and pause for 1 second) to balance drainage efficiency and energy consumption; it can optionally be linked with the main controller of the central control equipment (the main controller is also the control component), and automatically increase the equipment temperature (e.g., heat to 40℃) when triggered to accelerate liquid evaporation.

[0081] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: This utility model improves the efficiency of active liquid discharge through the synergistic effect of dynamic vibration and the guide section. It improves product lifespan and protective effect, implements an intelligent triggering mechanism, and plays a role in preventing blockage and draining. Correspondingly, the embodiments of this utility model can reduce the occurrence of internal corrosion or short circuits caused by small liquid residues, avoid the situation where drainage efficiency is reduced due to dust clogging of static drainage holes, and solve the technical problem in the prior art where liquid is difficult to completely drain when the tilt angle is insufficient.
