Description

Technical Field

[0001] This invention belongs to the field of humidification device technology, and more specifically, relates to a mobile humidification device based on distributed sensing. Background Technology

[0002] As people's demands for quality of life and indoor environmental comfort continue to rise, humidifiers have been widely used in various scenarios such as mother and baby rooms, laboratories, and offices. Stable and precise humidity control is especially crucial for humidity-sensitive individuals and environments storing precision equipment. However, existing humidifiers still have many technical shortcomings in practical applications, making it difficult to meet the needs of high-quality humidity control. Specific problems are as follows:

[0003] Insufficient humidity control precision and limited coverage: Traditional humidifiers are mostly fixed designs, capable of humidifying only a surrounding localized area. They cannot detect humidity differences between different areas of the room, resulting in uneven humidity distribution. Some dry areas fail to receive effective humidification, while areas near the device are prone to over-humidification. Furthermore, existing devices often use single-point temperature and humidity sensors, providing limited data that cannot comprehensively reflect indoor humidity gradients. This leads to a lack of targeted humidification strategies, low control precision, and difficulty in adapting to scenarios requiring high humidity accuracy.

[0004] Low humidification efficiency and serious water waste: Existing humidification devices have a relatively simple contact method between airflow and humidification medium, resulting in short residence time of the airflow in the humidification area, insufficient water evaporation, and low humidification efficiency. Furthermore, during humidification, condensation easily forms due to temperature differences as the humidified airflow flows within the duct. This condensation mostly drips directly or dissipates without effective recovery, leading to water waste. Simultaneously, some devices have unreasonable water supply structure designs and unstable water replenishment rates, further affecting humidification efficiency.

[0005] Poor hygiene and lack of maintenance convenience: The water tanks of traditional humidifiers are mostly fixed structures, which are inconvenient to disassemble and assemble. After long-term use, bacteria and mold are easy to grow inside, and it is difficult to clean them thoroughly. This causes the humidified air to carry pollutants, which affects human health. They are especially unsuitable for scenarios with strict hygiene requirements, such as mother and baby rooms and laboratories.

[0006] Weak autonomous operation capabilities and poor user experience: Existing portable humidifiers mostly rely on manual control of their movement, lacking autonomous navigation and obstacle avoidance functions. They are prone to colliding with furniture and walls in complex indoor environments and cannot automatically locate the drying area. In addition, the devices have limited battery life, requiring manual relocation to the charging position when the battery is low, which is cumbersome. The operation interface of some devices is not intuitive and cannot display key operating parameters in real time, making it difficult for users to accurately control the humidification status.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In this invention, distributed SHT30 temperature and humidity sensors collect indoor temperature and humidity data at multiple points. Combined with the obstacle detection function of obstacle avoidance radar and the K-means clustering analysis and path planning algorithm of the electronic control components, the device can accurately locate the dry area and autonomously move and navigate. This solves the problems of limited coverage and uneven humidity control of traditional humidification devices, and achieves precise humidity control throughout the indoor area.

[0020] In this invention, a servo motor drives a rotating column, a V-shaped connecting rod, and a segmented arc plate to work together. The turbulence intensity is dynamically adjusted according to the humidity difference, extending the contact time between the airflow and the water film of the humidifying net. This extends the residence time of the airflow in the dry state from 0.1s to 0.25s, significantly improving the efficiency of cold evaporation humidification, while avoiding over-humidification when the humidity is close to the target value.

[0021] In this invention, a complete condensation recovery path is constructed through the combined design of the PTFE waterproof coating of the segmented arc plate, the V-groove of the V-shaped connecting rod, the axial guide groove of the rotating column, and the conical water guide block. This achieves efficient condensation recovery and water tank return during humidification, increasing water resource utilization by more than 40%. Furthermore, the partition can prevent high-humidity air from entering the water tank, inhibit bacterial growth, and ensure the hygiene of water supply and humidification.

[0022] In this invention, a built-in 10000mAh high-energy-density lithium polymer battery pack, combined with a magnetic charging base and electronic control components, enables the device to autonomously plan the optimal path back to charge when the battery is low. It can be fully charged in 3 hours and can work continuously for more than 10 hours in low-speed movement + medium-gear humidification mode, meeting the long-term humidification needs of large apartments.

[0034] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0035] Please see Figures 1-9This invention provides a mobile humidification device based on distributed sensing, including a charging base 1, an obstacle avoidance radar 2, a base 3, a variable speed motor 4, a water tank module 5, a humidification net 6, a temperature and humidity sensor 7, a built-in battery 8, an upper shell assembly 9, an electronic control assembly 10, an electronic control cover 11, a display panel 12, a high-pressure impeller 13, an exhaust motor 14, an inner filter 15, a segmented arc plate 16, a V-shaped connecting rod 17, a servo motor 18, a conical water guide block 19, a partition 20, and a rotating column 21. The device has a modular columnar design and is divided into a charging adapter layer, a mobile drive layer, a humidification water storage layer, a core function layer, and an air outlet control layer from top to bottom. The components of each layer are fixedly connected by buckles, bolts, or integrated injection molding. Through the coordinated operation of distributed temperature and humidity acquisition, autonomous mobile navigation, and dynamic turbulent humidification, it can achieve precise humidity control throughout the indoor area, making it suitable for scenarios with high requirements for humidity accuracy and hygiene, such as mother and baby rooms, laboratories, and offices.

[0036] Specifically, refer to Figure 3 and Figure 4 As shown, the base 3 is made of ABS engineering plastic, ABS and PC alloy material, which enhances rigidity and moisture resistance. It is integrally molded and serves as the core mounting carrier of the mobile drive layer. Four rubber casters are symmetrically mounted on its bottom to achieve omnidirectional flexible movement. The base 3 integrates a variable speed motor 4 and an obstacle avoidance radar 2. The obstacle avoidance radar 2 is embedded in the reserved mounting slot at the front of the base 3. It adopts ultrasonic detection technology with a detection frequency of 10Hz and a detection range of 0.5-3 meters. It can collect information on obstacles such as furniture and walls in the surrounding environment in real time and transmit data to the electronic control component 10 every 100ms via serial communication. The variable speed motor 4 is a DC brushless motor with an adjustable speed range of 50-300 rpm. Its output shaft is connected to the caster drive shaft by a key connection and a locking nut. Under the control of the pulse width modulation (PWM) signal of the electronic control component 10, it realizes the linear movement, turning and fixed-point stopping of the device with a movement accuracy of ±5cm.

[0037] It should be noted that the charging base 1 uses a non-slip rubber base and has a built-in charging management module that integrates overcharge, over-discharge, and short-circuit protection functions. The top has two magnetic charging contacts that match the built-in battery 8, with an attraction force of ≥8N to ensure stable docking. When the device detects that the battery level is below 20% through the battery level detection module of the built-in battery 8, the electronic control component 10 will automatically plan the optimal path back to the charging base 1 and control the variable speed motor 4 to drive the device to move above the charging base 1. The device will then complete precise docking and charging through the magnetic contacts. The charging voltage is 12V, the charging current is 2A, and it can be fully charged in about 3 hours. The built-in battery 8 is a 10000mAh lithium polymer battery pack with a single cell voltage of 3.7V, a 4-series 3-parallel combination, and an energy density of ≥200Wh / kg. It can provide stable power supply for all electrical components and can work continuously for more than 10 hours in low-speed movement + medium-speed humidification mode, meeting the long-term humidification needs of large homes.

[0038] Specifically, refer to Figure 5 , Figure 6 and Figure 7 As shown, the humidifying water storage layer is located above the base 3 and is fixedly connected to the base 3 by a buckle. It mainly includes a water tank module 5, a partition 20, and a conical water guide block 19. The water tank module 5 adopts a magnetic detachable design. Two neodymium iron boron magnetic blocks are set on the outside of the water tank, and ferromagnetic sheets are set at corresponding positions on the body. The adsorption force is ≥5N, and it will not fall off when tilted at 30°. The volume is 2L, and a built-in float-type liquid level sensor is installed. When the water level is lower than 10%, the display panel 12 will issue a low water level warning. The water tank module 5 continuously replenishes water to the humidifying net 6 through a gravity water supply structure. The water tank module 5 has a submersible pump inside. When the device detects that the humidifying net is dry, it will automatically draw water from the water tank and then the water flows down from the top of the humidifying net 6, thereby maximizing the humidification. Its bottom is equipped with A 5mm diameter guide hole connects to the absorbent cotton at the bottom of the humidifying net 6 via a food-grade silicone tube, utilizing capillary action to achieve uniform water replenishment at a rate ≥2ml / min. The partition 20 is made of waterproof and breathable material, a composite structure of PTFE breathable membrane and PET support layer, horizontally installed between the top of the water tank module 5 and the bottom of the humidifying net 6. Its edges are sealed to the inner wall of the device with EVA foam sealing strips, preventing high-humidity air around the humidifying net 6 from intruding into the water tank module 5 without affecting airflow. The conical water guide block 19 is made of PPR material, resistant to high temperatures up to 70℃ and corrosion, with a 60° cone angle. It is fixed to the center of the rotating column 21 with screws, the tip pointing upwards, and has a smooth, polished surface. It is used to precisely guide the condensate to the return port of the water tank module 5.

[0039] It should be noted that the humidifying mesh 6 is arranged vertically in a cylindrical shape, with a height of 15cm and a diameter of 8cm. It is made of plant fiber material that is a blend of coconut shell fiber and polyester fiber, with a porosity of 80% and a capillary water absorption rate of ≥2ml / min. It can quickly absorb water to form a uniform water film, ensuring stable cold evaporation humidification efficiency. The inner filter 15 is integrally formed with the humidifying mesh 6. The mesh is evenly distributed in a regular hexagonal honeycomb pattern with a mesh diameter of 0.2mm. It has a filtration efficiency of ≥90% for particles ≥0.3μm. It has both air filtration and humidification carrier support functions, which can effectively block dust, fibers and other impurities from entering the internal air duct, ensuring the hygiene of the humidified air, while avoiding impurities from clogging the air duct and affecting airflow.

[0040] Specifically, refer to Figure 7 and Figure 8 As shown, the core functional layer is the key to achieving dynamic and precise humidification. It has four sets of segmented arc-shaped plates 16. Each set is an arc-shaped strip that fits the inner wall of the inner filter 15. The arc length is about 1 / 4 of the circumference, the radial protrusion height is 5mm, and the axial length is consistent with the height of the humidifying mesh 6. The segmented arc-shaped plates 16 are made of ABS and PC alloy engineering plastic to enhance rigidity and moisture resistance. The surface is sprayed with a 0.1mm thick PTFE waterproof coating. The two ends of the arc-shaped strip are designed with rounded corners to avoid scratching the inner filter 15. The arc-shaped strip does not damage the integrity of the water film on the inner side of the humidifying mesh 6, and can guide the airflow passing through the humidifying mesh 6 to form slight turbulence, prolonging the contact time between the airflow and the water film and improving the humidification efficiency.

[0041] It should be noted that the V-shaped connecting rod 17 is made of silicone material with a Shore hardness of 50A, and corresponds one-to-one with the segmented arc plate 16. It is fixedly connected by hot melt bonding. The top of the V-shaped connecting rod 17 is provided with a V-shaped groove, and the inner wall of the groove is smoothly polished to facilitate the rapid flow of condensate. The bottom is provided with an elastic buckle, and the rotating column 21 is provided with a corresponding slot. After the buckle is inserted into the slot, it is locked by elastic deformation. When disassembling, the buckle can be pressed to separate it, which is convenient for disassembly and assembly. The rotating column 21 is made of 304 stainless steel, with a diameter of 10mm and a length of 18cm. Four axial guide grooves are evenly distributed on the surface, which are connected with the V-shaped groove of the V-shaped connecting rod 17 to form a complete condensate guide path. The bottom of the rotating column 21 extends to the conical water guide block 19 and is fixedly connected.

[0042] Specifically, refer to Figure 4As shown, servo motor 18 is a miniature DC servo motor with a rated voltage of 12V and a rated power of 5W, model MG90S. It is fixed below the electronic control component 10 by a motor bracket. A shock-absorbing pad is placed between the motor bracket and the upper shell component 9 to reduce vibration transmission during motor operation. The output shaft of servo motor 18 is connected to the rotating column 21 via a flexible coupling. The speed is adjustable from 0-3 rpm, with a speed control accuracy of ±0.1 rpm. The electronic control component 10 is equipped with an STM32F407 ARM Cortex-M4 microcontroller, integrating humidity gradient recognition, path planning, and humidification matching algorithms. It is sealed inside the upper shell component 9 by an electronic control cover 11. The electronic control cover 11 is made of transparent PC material and has a silicone sealing ring between it and the upper shell component 9, with a waterproof rating of IP54, facilitating observation of the working status of the electronic control component 10. The electronic control component 10 can automatically adjust the start / stop and speed of servo motor 18 based on the humidity difference value collected by the temperature and humidity sensor 7, achieving dynamic adaptation of turbulence intensity.

[0043] It should be noted that the reference Figure 6 As shown, the air outlet control layer is fixed to the top of the upper shell assembly 9 and consists of an exhaust motor 14, a high-pressure impeller 13, and a display panel 12. The exhaust motor 14 is a brushless DC motor, which is fixed to the motor mount on the top of the upper shell assembly 9 by bolts. A shock-absorbing rubber pad is placed between the motor mount and the upper shell assembly 9 to reduce vibration and noise. The output shaft of the exhaust motor 14 is rigidly connected to the high-pressure impeller 13 by set screws. The high-pressure impeller 13 is made of ABS engineering plastic and has twelve arc-shaped blades. When working, it can generate a wind pressure of ≥50Pa, which drives the high-pressure impeller 13 to rotate and generate negative pressure, so that external air is drawn in from all sides of the device, humidified by the humidifying net 6, and discharged from the top air outlet. The wind speed is adjustable from 1 to 3 m / s to meet the humidification needs of different humidity scenarios. The display panel 12 is a 2.4-inch LCD capacitive touch screen, which is embedded in the reserved slot at the front of the upper shell assembly 9. It can display the current indoor humidity, target humidity, motor speed, battery level, and working mode icon in real time, and supports users to manually set the target humidity and working mode.

[0044] Specifically, refer to Figure 1 and Figure 7As shown, the temperature and humidity sensor 7 uses an SHT30 digital temperature and humidity sensor, with four sets arranged in a distributed manner: two sets are installed around the upper shell component 9, and two sets are installed on the side of the base 3. Each sensor is installed by a snap-on mounting bracket. Data transmission uses the I2C communication protocol, transmitting temperature and humidity data to the electronic control component 10 every 500ms. The electronic control component 10 processes the collected multi-point humidity data through a built-in K-means clustering analysis algorithm, analyzes and determines the specific location and humidity difference of the dry area indoors, and combines the obstacle information collected by the obstacle avoidance radar 2 to plan the optimal movement path through a path planning algorithm, controlling the variable speed motor 4 to drive the device to move precisely to the dry area, realizing precise control of humidification where it is dry.

[0045] It should be noted that the reference Figure 4 and Figure 7 As shown, the electronic control component 10 automatically adjusts the working state of the servo motor 18 based on the humidity difference value collected by the temperature and humidity sensor 7 through a PID adjustment algorithm to achieve dynamic adaptation of turbulence intensity: when the humidity difference value is >15%RH (the indoor environment is dry), the electronic control component 10 controls the servo motor 18 to rotate at a low speed of 1-3 revolutions per minute, driving the rotating column 21 and the segmented arc plate 16 to rotate synchronously, so that the relative contact angle between the segmented arc plate 16 and the airflow continuously changes, the turbulence distribution is more uniform and the intensity is slightly increased, and the residence time of the airflow inside the humidification net 6 is extended from 0.1s to 0.25s, significantly improving the contact efficiency between air and water vapor and accelerating the humidity increase speed in the dry area; when the humidity difference value is <5%RH (the indoor humidity is close to the target value), the electronic control component 10 controls the servo motor 18 to stop or rotate very slowly (speed ≤0.5 revolutions per minute), the segmented arc plate 16 maintains a fixed angle, maintains a weak turbulence state, avoids excessive humidification leading to local humidity exceeding the standard, and ensures that the indoor humidity is stable within the target range.

[0046] Specifically, refer to Figure 3 and Figure 4 As shown, during the humidification process, when the humidified airflow flows through the internal air duct, due to the temperature difference between the inner wall of the air duct and the airflow, some water vapor will form condensation beads on the surface of the segmented arc plate 16. Thanks to the PTFE waterproof coating on the surface of the segmented arc plate 16, the condensation beads flow quickly along the coating to the V-groove of the V-shaped connecting rod 17 under the action of gravity. After being gathered in the V-groove, they are guided into the axial guide groove of the rotating column 21. The condensation beads flow downward along the guide groove of the rotating column 21 and finally drip onto the tip of the conical water guide block 19. Under the action of gravity, they slide down along the smooth surface of the conical water guide block 19 and flow back accurately into the water tank module 5 through the return hole on the partition 20, realizing the recycling and reuse of condensation and improving the water resource utilization rate by more than 40%. At the same time, the partition 20 effectively blocks the high humidity air around the humidification net 6 from entering the water tank module 5, avoiding excessive humidity in the water tank and the growth of bacteria, and ensuring the hygiene of the water supply.

[0047] Working principle

[0048] In the first step, after the user turns on the device through the display panel 12 and sets the target humidity (30%-60%RH), the four distributed temperature and humidity sensors 7 start up simultaneously, collecting temperature and humidity data of each area in the room in real time, and transmitting the data to the electronic control component 10 every 500ms, providing accurate basis for humidification decision.

[0049] In the second step, after the STM32F407 microcontroller of the electronic control component 10 receives multi-point temperature and humidity data, it identifies the indoor humidity gradient through the K-means clustering analysis algorithm to determine the specific location and humidity difference of the dry area (humidity lower than the target humidity). At the same time, the obstacle avoidance radar 2 collects obstacle information of the surrounding environment in real time and transmits it to the electronic control component 10. The microcontroller plans the optimal movement path from the current position to the dry area through the path planning algorithm, avoiding obstacles such as furniture and walls.

[0050] Third, the electronic control component 10 sends a PWM control signal to the variable speed motor 4 to drive the omnidirectional wheel to move the device along the planned path. During the movement, the obstacle avoidance radar 2 continuously monitors obstacles. If a new obstacle is detected, the electronic control component 10 adjusts the path in real time. When the device moves to the center of the drying area, the gravity positioning sensor integrated inside the base 3 triggers the positioning signal, and the electronic control component 10 controls the variable speed motor 4 to stop, achieving fixed-point stopping.

[0051] In the fourth step, after the device is positioned, the electronic control component 10 starts the exhaust motor 14, which drives the high-pressure impeller 13 to rotate and generate negative pressure. External air is drawn in from all around the device and passes through the uniform water film on the surface of the humidifying mesh 6 for cold evaporation humidification, forming a humid airflow. Dust, fibers and other impurities are filtered out by the inner filter 15. At the same time, the electronic control component 10 adjusts the speed of the servo motor 18 according to the humidity difference: when the humidity difference is >15%RH, the servo motor 18 rotates at a low speed of 1-3 revolutions per minute, driving the segmented arc plate 16 to rotate synchronously, making the turbulence distribution more uniform and slightly increasing the intensity, prolonging the contact time between the airflow and the water film, and improving the humidification efficiency; when the humidity difference is <5%RH, the servo motor 18 stops or rotates very slowly to maintain weak turbulence and avoid over-humidification.

[0052] Fifth, during the humidification process, the condensation formed by the humid airflow in the air duct flows along the PTFE coating of the segmented arc plate 16 to the V-groove of the V-shaped connecting rod 17, and is guided by the guide groove of the rotating column 21 to the conical water guide block 19, and finally flows back to the water tank module 5 for recycling; the partition 20 prevents high humidity air from entering the water tank, inhibits bacterial growth, and ensures the hygiene of the humidified air.

[0053] Step 6: After the humidity in the drying area reaches the target value, the temperature and humidity sensor 7 feeds the data back to the electronic control component 10. The microcontroller control device moves to the next drying area and repeats the above humidification process until the overall indoor humidity reaches the set range. The device then enters standby mode. If the built-in battery 8 is detected to be below 20% charge, the electronic control component 10 plans a return path, and the control device automatically moves to the charging base 1. It then connects to the charging base via magnetic contacts for charging. Once fully charged, it enters standby mode, waiting for the next working instruction.

[0054] The entire process requires no human intervention, achieving full automation from humidity sensing, autonomous movement, precise humidification, and condensation recovery. It ensures the uniformity and accuracy of indoor humidity, while also improving humidification efficiency and water resource utilization. It is suitable for scenarios with high requirements for humidity accuracy and hygiene, such as mother and baby rooms and laboratories.
