Description

Technical Field

[0001] The present invention relates to a visual large-humidification-capacity humidifier and a humidifying method thereof, belonging to the field of humidification. Background Art

[0002] Traditional humidifiers are mainly divided into two types: evaporative and ultrasonic. Evaporative humidifiers increase air humidity through the natural evaporation of water, but the humidifying speed is slow and the humidification capacity is small. It relies on the natural volatilization of water molecules, and this process is significantly affected by factors such as environmental temperature, humidity, and air flow. In a dry and well-ventilated environment, the efficiency of evaporative humidifiers will be further reduced, making it difficult to quickly increase air humidity and thus unable to meet the user's demand for rapid humidification.

[0003] Ultrasonic humidifiers use ultrasonic atomization technology to atomize water into tiny particles. The humidifying speed is fast, but it will produce a white powder phenomenon and the humidification capacity is limited. During the ultrasonic atomization process, minerals and impurities in the water will be atomized together. When these tiny particles adhere to the surface of objects or air filters, a layer of white powder will be formed, which not only affects indoor cleanliness but may also have a potential impact on air quality. In addition, although the humidifying speed of ultrasonic humidifiers is relatively fast, their atomization ability is still limited by the power of the ultrasonic generator and the capacity of the water tank. When facing large-area spaces or long-term humidification requirements, they will also seem inadequate.

[0004] In addition, traditional humidifiers mostly adopt a single humidifying method and are difficult to meet the high-humidification-capacity requirements in large-area spaces or special scenarios. Due to the limitation of its humidifying principle, the humidification capacity of evaporative humidifiers is small by itself and cannot be competent for places with high humidity requirements, such as large offices, shopping malls, exhibition halls, etc. Although ultrasonic humidifiers have a relatively fast humidifying speed, when used alone, their humidification capacity is also difficult to continuously meet the needs of large-area spaces. Especially in an open environment, their humidifying effect will rapidly decay with the increase of distance.

[0005] Some humidifiers, in order to pursue large capacity and large humidification capacity, adopt a simple and direct structural design, resulting in an overly large overall volume, which is not convenient for placement and use in scenarios such as homes and offices. Some traditional large humidifiers, in order to increase the water tank capacity and the size of the humidifying components, often adopt a simple structure of stacking up and down or expanding horizontally, which greatly increases the volume and weight of the humidifier. In a home environment, these huge humidifiers will occupy valuable indoor space and affect the layout and aesthetics of the room. In an office scenario, they not only occupy office space but may also be inconvenient to move and clean due to their large size, bringing many inconveniences to the actual use of users. Summary of the Invention

[0006] To overcome the defects of the prior art, the present invention provides a visual large-humidification-capacity humidifier. The technical solution of the present invention is as follows:

[0008] A housing;

[0009] A suspension tower (1), arranged at the top of the housing, for guiding water vapor to flow downward to form a waterfall-like visual water mist effect;

[0010] An upper water tank (2), arranged on the housing below the suspension tower (1), for storing water source. An upper air guiding cavity and an upper water vapor air duct communicating with the suspension tower (1) are arranged inside the upper water tank (2); the upper water tank is arranged in a transparent manner;

[0011] A lower water tank (3), arranged on the housing below the upper water tank (2), for accommodating a humidifying film assembly (4). A water volume adjusting mechanism is arranged between the lower water tank (3) and the upper water tank (2). An air outlet grille is arranged at the top of the lower water tank for discharging the humidified air flow;

[0012] An air supply unit (6), arranged at the lower part of the housing, for driving the air flow to flow around the humidifying film assembly (4) and for driving the air flow to enter the lower water vapor air duct and the upper water vapor air duct.

[0013] The suspension tower (1) includes an upper cover and a lower cover connected to the upper cover by screws. A receiving buffer cavity is formed between the lower cover and the upper cover. A plurality of arc-shaped air outlets for water vapor to overflow are evenly distributed on the lower cover; the lower cover is installed on the upper water tank by a buckle and is close to the upper water vapor air duct.

[0014] The upper water tank includes an upper water tank body and a water tank top cover. A spacing is formed between the water tank top cover and the lower cover; the overall shape of the upper water tank body is conical. The lower part of the upper water tank body is nested in the lower water tank (3), and the upper water vapor air duct is communicated with the lower water vapor air duct arranged in the lower water tank (3).

[0015] The water volume adjusting mechanism includes a water level float, a spring, a rubber plug and a plastic driving column. A rubber plug is installed at the water outlet at the bottom of the upper water tank in a liftable manner. The head of the water level float is hinged inside the lower water tank (3). A protrusion is formed at one end of the water level float. The protrusion is located at the bottom of the rubber plug and is in moving fit with the rubber plug to lift or move away from the rubber plug. A plastic driving column for counterweight is installed at the other end. The spring is installed between the bottom of the upper water tank and the upper step of the plastic driving column to give a downward driving force to the rubber plug; the water level float, the protrusion and the plastic driving column together form a lifting trigger lever mechanism.

[0016] The upper part of the humidifying film assembly is fixed to the side wall of the upper water tank by interference fit, and a sealing sponge is pasted around the top of the humidifying film assembly; the humidifying film assembly includes a humidifying upper bracket, a humidifying lower bracket and a humidifying film, and the humidifying film is located between the humidifying upper bracket and the humidifying lower bracket; the air flow output by the air supply unit passes through the humidifying film and then enters the air outlet grille, and the other part passes through the humidifying film and then enters the air guiding cavity and the upper water vapor air duct in sequence.

[0017] A bottom cover of the box body is arranged at the bottom of the lower water tank, and a lower air guiding cavity communicated with the air supply unit is arranged at the side part of the lower water tank, and the lower air guiding cavity corresponds to the humidifying film; a space for accommodating the main control board is formed between the bottom cover of the box body and the bottom of the box body of the lower water tank.

[0018] An ultrasonic module is installed at the bottom inside the lower water tank, and a sealing ring is installed between the ultrasonic module and the upper water tank; the ultrasonic module is used for receiving the water flow in the lower water tank and performing ultrasonic atomization.

[0019] The air duct of the air supply unit (6) discharges air around the humidifying film assembly to increase the contact area between the air flow and the humidifying film.

[0020] A humidifying method based on the visualized large humidifying capacity humidifier is characterized by comprising the following steps:

[0021] Step S1: Water source supply and dynamic water level regulation: The upper water tank (2) supplies water to the lower water tank (3) through the bottom water outlet, and the water volume regulating mechanism dynamically regulates the water level based on the lever balance equation; when the water level drops, the water level float triggers the rubber plug to rise through the moment balance of the hinge point, and the water outlet flow is increased; when the water level reaches the set threshold, the counterweight of the plastic driving column presses down the float end, and the rubber plug closes the water outlet; the lever balance equation is:

[0022] F 浮 ·L 1 =F 配重 ·L 2 +F 摩擦 ;

[0023] Among them, F 浮 is the buoyancy force, L 1 and L 2 are the force arm lengths, and F 摩擦 is the friction force between the rubber plug and the water outlet to ensure that the water level is stable within an error range of ±2 mm.

[0024] Step S2: Ultrasonic atomization and air flow distribution control

[0025] The water in the lower water tank (3) is atomized by the ultrasonic module, and the atomization rate Q 雾Satisfy with the driving frequency f and power P:

[0026] Wherein, k is the material coefficient, and f 0 is the reference frequency; meanwhile, the air supply unit (6) divides the air flow into two paths:

[0027] The first path of air flow: after vertically penetrating and humidifying through the humidifying film assembly (4), it is discharged from the air outlet grille, and its flow rate ratio α is dynamically adjusted by the PID algorithm according to the ambient humidity difference ΔH, and satisfies:

[0028]

[0029] The second path of air flow: enters the upper water vapor air duct, and forms a visual waterfall water mist through the arc-shaped air outlet of the suspension tower (1), and its flow velocity v is calculated by Bernoulli's equation:

[0030] Wherein, P cavity is the air pressure in the buffer cavity, P outside is the external air pressure, and ρ air is the air density.

[0031] Step S3: Visual water mist enhancement and humidity feedback

[0032] The arc-shaped air outlet design of the suspension tower (1) enables the water mist to diffuse downward in a laminar flow state, and the coverage angle θ satisfies:

[0033] Wherein, D air outlet is the diameter of the air outlet, and R curvature is the arc radius; the ambient humidity sensor continuously detects the humidity value H actual, if the deviation from the set value H target exceeds 5%, then through adjusting the rotation speed n of the air supply unit and the ultrasonic power P for closed-loop control, so that:

[0034]

[0035] Wherein, β is the attenuation coefficient, ensuring that the humidification rate matches the humidity demand.

[0036] Step S4: Safety protection and energy efficiency optimization

[0037] When the water level in the upper water tank (2) is lower than the lowest threshold or the lower water tank (3) continuously atomizes for more than 30 minutes, the main control board triggers shutdown protection; the penetration efficiency η of the humidifying film assembly (4) is optimized by the following formula:

[0038] Wherein, γ is the film material penetration coefficient, S is the effective contact area, t is the air flow passing time, and S is increased by increasing the circumferential air outlet area of the air supply unit;

[0039] Step S5: Cooperative humidification mode

[0040] Using ultrasonic atomization and humidifying film penetration, the total humidification amount Q 总 is: Q总 = Q 雾 + α·Q 膜 ; where Q 膜 is the evaporation rate of the humidifying membrane per unit time;

[0041] Step S6: Intelligent dynamic adjustment of humidification amount

[0042] The indoor temperature T and humidity H are collected in real time through an environmental sensor 实际 , the user-set humidity H 目标 , the air quality index PM2.5, and the user behavior pattern data are input into the fuzzy control model; the fuzzy control model generates a humidification amount adjustment factor λ based on the following rules:

[0043] When ΔH = H 目标 - H 实际 > 10%, λ is increased to 1.5 times the reference value, and the ultrasonic power P is preferentially increased;

[0044] When ΔH < 5% and PM2.5 > 75, the air flow ratio α of the humidifying membrane is reduced to reduce the diffusion of water mist to avoid particle sedimentation;

[0045] According to the user's historical usage period data, the rotation speed n of the air supply unit is automatically reduced to the silent mode n ≤ 800 rpm at night; the adjustment factor λ controls the humidification parameters through the following formula:

[0046]

[0047] where P 0 , n 0 , α 0 are reference parameters, which are dynamically updated through historical data; k1 is the humidity compensation coefficient, τ is the time decay constant, T reference = 20 °C; t represents the current usage period of the user;

[0048] Step S7: Fault prediction and maintenance warning

[0049] The following parameters are collected through multi-source sensors to construct a time series data set:

[0050] The total harmonic distortion THD of the ultrasonic module; the pressure difference ΔP on both sides of the humidifying membrane; the vibration spectrum f of the air supply unit v and the bearing temperature T 轴承 ;

[0051] A hybrid neural network model combining the temporal convolutional network TCN and LSTM is used to input the data set for training to predict the failure probability P within the next τ = 24 hours fault ;

[0052] When P fault ≥ 0.7, a three-level warning mechanism is triggered:

[0053] Primary warning, 0.7 ≤ P fault < 0.8: Prompt "It is recommended to clean the humidifying film" through the LED indicator light;

[0054] Intermediate warning, 0.8 ≤ P fault < 0.9: Push "The ultrasonic module efficiency has decreased, need to detect" through the APP;

[0055] Advanced warning, P fault ≥ 0.9): Forcefully enter the low-power safety mode and generate a maintenance report, including: when the average monthly growth rate of ΔP ≥ 5%, determine that the risk level of the humidifying film blockage is high;

[0056] When THD ≥ 15%, determine that the capacitor of the ultrasonic module is aging;

[0057] When f v The main frequency offset ≥ 10% and T bearing > 60 °C, determine that the bearing of the air supply unit needs to be replaced. The advantages of the present invention are:

[0058] Achieve the purpose of significantly improving the humidifying capacity. Adopt a unique double-tank structure and the design of the humidifying film assembly, combine the evaporative and ultrasonic humidifying methods, output a large humidifying capacity, and meet the needs of different scenarios. At the same time, make reasonable use of space, make the upper water tank conical and half sink into the lower water tank, and greatly reduce the volume of the humidifier without reducing the performance, making it more suitable for the home and office environments.

[0059] The periphery of the humidifying film is exposed to the air, and the middle is immersed in water, which not only reduces the wind resistance but also increases the windward area, improving the humidifying capacity.

[0060] By combining the evaporative and ultrasonic humidifying methods or increasing the water backflow effect, visually display the humidifying process, enhance the interest and ornamental value, and through ingenious design and optimization, achieve an overall improvement in the humidifying capacity, volume, maintenance convenience, structural rationality, and visualization effect of the humidifier, providing users with a humidifying product with excellent performance, convenient use, and novel appearance.

[0070] The present invention will be further described below in conjunction with specific embodiments, and the advantages and features of the present invention will become clearer as the description progresses. However, these embodiments are exemplary only and do not constitute any limitation to the scope of the present invention. Those skilled in the art should understand that modifications or substitutions can be made to the details and forms of the technical solutions of the present invention without departing from the spirit and scope of the present invention, but these modifications and substitutions all fall within the protection scope of the present invention.

[0071] Refer to Figures 1 to 9 , the present invention relates to a visual large-capacity humidifier, comprising:

[0072] A housing;

[0073] A suspension tower 1, arranged at the top of the housing, for guiding water vapor to flow downward to form a waterfall-like visual water mist effect;

[0074] An upper water tank 2, arranged on the housing below the suspension tower 1, for storing water source. An upper air intake cavity and an upper water vapor air duct communicating with the suspension tower 1 are arranged inside the upper water tank 2; the upper water tank 2 is arranged in a transparent shape;

[0075] A lower water tank 3, arranged on the housing below the upper water tank 2, for accommodating a humidification film assembly 4. A water volume adjusting mechanism is arranged between the lower water tank 3 and the upper water tank 2. An air outlet grille is arranged at the top of the lower water tank for discharging the humidified air flow;

[0076] A air supply unit 6, arranged at the lower part of the housing, for driving the air flow to flow around the humidification film assembly 4 and driving the air flow into the lower water vapor air duct and the upper water vapor air duct. The air duct of the air supply unit 6 discharges air around the humidification film assembly 4 for increasing the contact area between the air flow and the humidification film 42.

[0077] The setting of this large-humidification-capacity humidifier with visualization realizes the following advantages:

[0078] Visualization effect and aesthetics: The suspension tower design makes the structure seem to float in the water mist. The water vapor falls through the holes of the suspension tower to form a waterfall-like shape. Combined with the transparent design of the upper water tank, users can directly see the water level and the humidification operation status. The humidification process is visualized and ornamental.

[0079] Space utilization and structure optimization: The upper water tank is conical and half of it sinks into the lower water tank. This structure rationally utilizes space without changing the performance, greatly reducing the overall volume of the machine, achieving a large capacity in a small volume, and being convenient to place in different indoor environments.

[0080] Humidification efficiency and performance improvement: The humidification membrane assembly is located in the lower water tank, partially immersed in water and conical, with its periphery exposed to the air. This design reduces the wind resistance for rearward centrifugal fan products, allows the air to flow more smoothly through the humidification membrane, increases the windward area, significantly improves the humidification capacity compared with the cylindrical humidification membrane, and enhances the humidification efficiency.

[0081] Intelligent water volume adjustment: A water volume adjustment mechanism is provided between the upper and lower water tanks, including a drain valve and a water level float. When the water level float floats, the drain valve closes and the water in the upper water tank does not flow out; when the water level float sinks, the drain valve opens and the water in the upper water tank flows into the lower water tank. When the lower water tank is full, the water level float floats, and this action continues to achieve automatic water volume adjustment and ensure the stable operation of the humidifier.

[0082] The suspension tower 1 described above includes an upper cover 11 and a lower cover 12 connected to the upper cover 11 by screws. A receiving buffer cavity is formed between the lower cover 12 and the upper cover 11. A plurality of arc-shaped air outlets 21 for the overflow of water vapor are evenly distributed on the lower cover; the lower cover 12 is installed on the upper water tank 2 by a buckle and is close to the upper water vapor air duct.

[0083] The setting of this suspension tower realizes the following advantages:

[0084] Uniform overflow of water vapor: The design of the arc-shaped air outlets evenly distributed on the lower cover enables the water vapor to overflow from the suspension tower evenly, forming a soft and uniform water mist effect, avoiding uneven humidification and local over-wetting phenomena caused by the concentrated injection of water vapor, and improving the humidification effect and comfort.

[0085] Buffer and noise reduction: The receiving buffer cavity formed between the upper cover and the lower cover can play a certain buffering role in the flow of water vapor, reduce the noise generated by the direct impact of water vapor, make the humidifier run more quietly, and provide a comfortable use experience for users.

[0086] Aesthetics and Decorativeness: The overall design of the floating tower, including the shapes of the upper and lower covers, the arrangement of the arc-shaped air outlets, etc., not only has functionality but also enhances the aesthetics and decorativeness of the product, enabling it to better integrate into various indoor environments and improving the overall grade of the product.

[0087] Good cooperation with the upper water vapor duct: The lower cover is installed on the upper water tank through buckles and is close to the upper water vapor duct. This layout can ensure that water vapor smoothly enters the floating tower from the upper water vapor duct and evenly overflows through the arc-shaped air outlets, guaranteeing the reasonable flow of the air current inside the humidifier and the stable exertion of the humidification efficiency.

[0088] The upper water tank 2 mentioned above includes an upper water tank body and a water tank top cover 8. A spacing 13 is formed between the water tank top cover 8 and the lower cover mentioned above; the overall shape of the upper water tank body is conical, and the lower part of the upper water tank body is nested in the lower water tank 3, and the upper water vapor duct is communicated with the lower water vapor duct of the lower water tank 3.

[0089] The setting of this upper water tank realizes the following advantages:

[0090] Efficient space utilization: The upper water tank body is conical and its lower part is nested in the lower water tank. This design rationally utilizes space without changing the performance, greatly reducing the volume of the whole machine, realizing the characteristics of small volume and large capacity, and facilitating placement in different indoor environments.

[0091] Smooth water vapor flow: The spacing formed between the upper water tank body and the water tank top cover, as well as the communication design between the upper water vapor duct and the lower water vapor duct of the lower water tank, can ensure the smooth flow of water vapor inside the humidifier, reduce the resistance of water vapor in the duct, and improve the humidification efficiency.

[0092] Good structural stability: The conical design of the upper water tank body not only helps optimize the space but also increases the structural stability, making the upper water tank more stable when nested in the lower water tank and reducing the shaking and displacement during use.

[0093] Beautiful and harmonious appearance: The overall shape of the upper water tank is coordinated with other components of the humidifier. The conical design has smooth lines, increasing the aesthetics and modern sense of the product and making it easier to integrate into various home and office environments.

[0094] Convenient for installation and maintenance: The combined structure of the upper water tank body and the water tank top cover, as well as its nesting method with the lower water tank, enables users to disassemble and clean more conveniently during the installation and maintenance processes, which is conducive to maintaining the hygiene inside the humidifier and the stability of its performance.

[0095] Promote uniform distribution of water vapor: The design of the spacing helps to form a certain buffer and uniform distribution of water vapor before it enters the lower water tank, enabling the water vapor to pass through the humidifying film assembly more evenly and improving the uniformity and stability of the humidifying effect.

[0096] The described water volume adjustment mechanism includes a water level float 7, a spring, a rubber plug 14, and a plastic drive column 15. A rubber plug 14 is installed at the water outlet at the bottom of the upper water tank 2 in a liftable manner. The head of the water level float 7 is hinged inside the lower water tank 3. One end of the water level float 7 forms a protrusion 16, which is located at the bottom of the rubber plug 14 and is in movable fit with the rubber plug 14, pushing up or away from the rubber plug 14. The other end is installed with a plastic drive column 15 for counterweight. The spring is installed between the bottom of the upper water tank and the upper step of the plastic drive column, giving a downward driving force to the rubber plug. The water level float 7, the protrusion 16, and the plastic drive column 15 together form a lifting trigger lever mechanism.

[0097] This water volume adjustment mechanism has the following advantages:

[0098] Automatic control without manual intervention: Through the lever mechanism composed of components such as the water level float, rubber plug, and plastic drive column, it can automatically control the water outlet of the upper water tank according to the water level in the lower water tank, without manual operation, which is convenient to use.

[0099] Simple structure and high reliability: The whole mechanism is composed of a few components such as the water level float, rubber plug, and plastic drive column. The structure is relatively simple, reducing the failure points and improving the reliability of the system.

[0100] High sensitivity and timely response: The water level float can float up and down with the change of the water level in the lower water tank. Through the movable fit between the protrusion and the rubber plug, it can quickly push up or release the rubber plug, realizing the opening or closing of the water outlet of the upper water tank and ensuring the timely adjustment of the water level.

[0101] Clever design and space saving: This mechanism cleverly utilizes the lever principle and buoyancy principle, arranging the components compactly between the upper water tank and the lower water tank without occupying too much extra space, which is beneficial to the compactness of the overall structure.

[0102] Convenient maintenance and low cost: Due to the simple structure and few components, it is easy to disassemble and inspect during maintenance, and the cost of replacing components is relatively low, reducing the usage cost.

[0103] Strong adaptability and good versatility: The design of this water volume adjustment mechanism does not rely on complex electronic components or specific power supplies, and has strong adaptability and versatility. It can be applied to a variety of similar humidifiers or other devices that require water volume adjustment.

[0104] The upper part of the humidifying film assembly 4 is fixed to the side wall of the upper water tank 2 by interference fit, and a sealing sponge is pasted around the top of the humidifying film assembly 4; the humidifying film assembly 4 includes a humidifying upper bracket 41, a humidifying lower bracket 43 and a humidifying film 42, and the humidifying film 42 is located between the humidifying upper bracket 41 and the humidifying lower bracket 43; the air flow output by the air supply unit 6 passes through the humidifying film 42 and then enters the air outlet grille, and another part passes through the humidifying film 42 and then enters the air guiding cavity and the upper water vapor air duct in sequence.

[0105] The structure of this humidifying film assembly has the following advantages:

[0106] Stable installation: The upper part of the humidifying film assembly is fixed to the side wall of the upper water tank by interference fit. This connection method does not require additional fasteners, is simple to install and firmly connected, ensuring that the humidifying film assembly will not loosen during operation, and is stable and reliable.

[0107] Good sealing: A sealing sponge is pasted around the top of the humidifying film assembly, effectively preventing water vapor from leaking through the gap between the humidifying film assembly and the side wall of the upper water tank, ensuring the reasonable flow of the air flow inside the humidifier and the humidifying efficiency, and at the same time avoiding the influence of water vapor leakage on the surrounding environment and equipment.

[0108] Efficient humidification: The humidifying film is located between the humidifying upper bracket and the humidifying lower bracket. This design enables the humidifying film to be fully unfolded, increasing the contact area with the air and improving the humidifying efficiency. After the air flow output by the air supply unit passes through the humidifying film, it can fully carry away the water vapor and achieve a good humidifying effect.

[0109] Uniform humidification: After the air flow passes through the humidifying film, one part enters the air outlet grille, and the other part enters the air guiding cavity and the upper water vapor air duct in sequence. This air flow distribution method helps the water vapor to be evenly diffused inside the humidifier, avoiding excessive or insufficient humidification in local areas, and making the humidity distribution in the entire space more uniform.

[0110] Easy to maintain: The structure of the humidifying film assembly is relatively simple, consisting of a humidifying upper bracket, a humidifying lower bracket and a humidifying film, which is convenient for disassembly and cleaning. When maintenance or replacement of the humidifying film is required, it can be completed with simple operations, reducing the maintenance difficulty and cost.

[0111] A box bottom cover 9 is provided at the bottom of the lower water tank 3, and a lower air guiding cavity communicating with the air supply unit 6 is provided at the side of the lower water tank 3, and the lower air guiding cavity corresponds to the humidifying film 42; a space for accommodating the main control board is formed between the box bottom cover 9 and the box bottom of the lower water tank 3.

[0112] The structure of this ultrasonic module has the following advantages:

[0113] The ultrasonic module is installed at the bottom of the lower water tank and can directly receive the water flow in the lower water tank and perform ultrasonic atomization. This design enables the water to be atomized into fine water droplets quickly and efficiently, improving the humidification efficiency.

[0114] A sealing ring is installed between the ultrasonic module and the upper water tank, effectively preventing water from leaking through the gap between the two, ensuring that the water inside the humidifier can be fully utilized, avoiding waste of water resources, and preventing water from leaking onto other components to cause damage or safety hazards.

[0115] Installing the ultrasonic module at the bottom of the lower water tank makes rational use of the internal space of the humidifier, making the structure of the entire device more compact, without occupying additional space, and facilitating the miniaturization and portability of the humidifier.

[0116] This installation method makes the installation and maintenance of the ultrasonic module relatively simple. When maintenance or replacement is required, only operations need to be carried out from the bottom of the lower water tank, without the need to disassemble the entire humidifier on a large scale, reducing the maintenance difficulty and cost.

[0117] The position and design of the ultrasonic module cooperate with other components of the humidifier such as the suspension tower and the humidification film assembly to jointly achieve the function of visual large humidification amount of the humidifier. The components work together to improve the overall performance and effect of the humidifier.

[0118] An ultrasonic module 10 is installed at the bottom inside the lower water tank 3. A sealing ring 23 is installed between this ultrasonic module and the upper water tank 2; this ultrasonic module 10 is used to receive the water flow in the lower water tank 3 and perform ultrasonic atomization.

[0119] The present invention also relates to a humidifying method based on the above-mentioned visual large humidification amount humidifier, which is characterized by including the following steps:

[0120] Step S1: Water source supply and dynamic water level adjustment: The upper water tank (2) supplies water to the lower water tank (3) through the bottom water outlet, and the water volume adjustment mechanism dynamically adjusts the water level based on the lever balance equation; when the water level drops, the water level float triggers the rubber plug to rise through the moment balance of the hinge point, opening the water outlet flow; when the water level reaches the set threshold, the counterweight of the plastic drive column presses down the float end, and the rubber plug closes the water outlet; the lever balance equation is:

[0121] F 浮 ·L 1 =F 配重 ·L 2 +F 摩擦 ;

[0122] Among them, F 浮 is the buoyancy force, L 1 and L 2 are the lever arm lengths, F摩擦 is the friction between the rubber stopper and the water outlet, ensuring that the water level is stable within an error range of ±2 mm.

[0123] Step S2: Ultrasonic atomization and air flow distribution control

[0124] The water in the lower water tank (3) is atomized by the ultrasonic module, and the atomization rate Q 雾 satisfies the following relationship with the driving frequency f and power P:

[0125] where k is the material coefficient and f 0 is the reference frequency; at the same time, the air supply unit (6) divides the air flow into two paths:

[0126] The first path of air flow: After being vertically humidified through the humidification film assembly (4), it is discharged from the air outlet grille, and its flow rate ratio α is dynamically adjusted by the PID algorithm according to the ambient humidity difference ΔH, satisfying:

[0127]

[0128] The second path of air flow: Enters the upper water vapor air duct and forms a visual waterfall water mist through the arc-shaped air outlet of the suspension tower (1). Its flow velocity v is calculated by Bernoulli's equation:

[0129] where P chamber is the air pressure in the buffer chamber, P outside is the external air pressure, and ρ air is the air density.

[0130] Step S3: Visual water mist enhancement and humidity feedback

[0131] The arc-shaped air outlet design of the suspension tower (1) enables the water mist to diffuse downward in a laminar flow state, and the coverage angle θ satisfies:

[0132] where D outlet is the diameter of the air outlet and R curvature is the arc radius; the ambient humidity sensor continuously detects the humidity value H actual. If the deviation from the set value H target exceeds 5%, then through closed-loop control by adjusting the rotation speed n of the air supply unit and the ultrasonic power P, making:

[0133]

[0134] where β is the attenuation coefficient, ensuring that the humidification rate matches the humidity demand.

[0135] Step S4: Safety protection and energy efficiency optimization

[0136] When the water level in the upper water tank (2) is lower than the lowest threshold or the lower water tank (3) continuously atomizes for more than 30 minutes, the main control board triggers shutdown protection; the permeation efficiency η of the humidification film assembly (4) is optimized by the following formula:

[0137] Among them, γ is the permeability coefficient of the membrane material, S is the effective contact area, t is the air flow through time, and S is increased by increasing the circumferential air outlet area of the air supply unit;

[0138] Step S5: Cooperative humidification mode

[0139] Using ultrasonic atomization and humidification membrane permeation, the total humidification amount Q 总 is: Q 总 = Q 雾 + α·Q 膜 ; where Q 膜 is the evaporation amount per unit time of the humidification membrane;

[0140] Step S6: Intelligent dynamic adjustment of humidification amount

[0141] The indoor temperature T, humidity H 实际 , user-set humidity H 目标 , air quality index PM2.5, and user behavior pattern data are collected in real time through environmental sensors and input into the fuzzy control model; the fuzzy control model generates a humidification amount adjustment factor λ based on the following rules:

[0142] When ΔH = H 目标 - H 实际 > 10%, λ is increased to 1.5 times the reference value, and the ultrasonic power P is preferentially increased;

[0143] When ΔH < 5% and PM2.5 > 75, reduce the air flow ratio α of the humidification membrane and reduce the water mist diffusion to avoid particulate deposition;

[0144] According to the user's historical usage time period data, automatically reduce the rotation speed n of the air supply unit to the silent mode n ≤ 800 rpm at night; the adjustment factor λ cooperatively controls the humidification parameters through the following formula:

[0145]

[0146] where P 0 , n 0 , α 0 are reference parameters, which are dynamically updated through historical data; k1 is the humidity compensation coefficient, τ is the time decay constant, T reference = 20 °C; t represents the current usage time period of the user;

[0147] Step S7: Fault prediction and maintenance warning

[0148] Collect the following parameters through multi-source sensors to construct a time series data set:

[0149] The total harmonic distortion THD of the ultrasonic module; the pressure difference ΔP on both sides of the humidification membrane; the vibration spectrum f of the air supply unit v and the bearing temperature T 轴承 ;

[0150] Adopt a hybrid neural network model that combines a temporal convolutional network (TCN) and an LSTM. Input the dataset for training to predict the failure probability P within the next τ = 24 hours. fault ;

[0151] When P fault ≥ 0.7, trigger a three - level warning mechanism:

[0152] Primary warning, 0.7 ≤ P fault <0.8: Prompt "It is recommended to clean the humidification membrane" through an LED indicator;

[0153] Intermediate warning, 0.8 ≤ P fault <0.9: Push "The ultrasonic module efficiency has decreased, need to be detected" through the APP;

[0154] Advanced warning, P fault ≥ 0.9): Forcefully enter the low - power safety mode and generate a maintenance report, including: When the monthly average growth rate of ΔP ≥ 5%, determine that the risk level of the humidification membrane blockage is high;

[0155] When THD ≥ 15%, determine that the capacitance of the ultrasonic module is aging;

[0156] When f v The main frequency deviation ≥ 10% and T 轴承 > 60 °C, determine that the bearing of the air supply unit needs to be replaced.

[0157] The control method of the large - humidification - amount humidifier based on visualization has the following advantages:

[0158] 1. High degree of intelligence and automation

[0159] Dynamic water - level adjustment: The water - level is dynamically adjusted by the water - volume adjustment mechanism based on the lever - balance equation. When the water - level drops, the water - level float triggers the rubber plug to rise through the moment balance at the hinge point, increasing the outlet flow rate; when the water - level reaches the set threshold, the counterweight of the plastic drive column presses down the float end, and the rubber plug closes the outlet. This automatic adjustment mechanism ensures precise control of the water - level without manual intervention, improving the intelligence level of the humidifier.

[0160] Humidity feedback and closed - loop control: The ambient humidity sensor continuously detects the humidity value. If the deviation from the set value exceeds 5%, closed - loop control is performed by adjusting the rotation speed of the air - supply unit and the ultrasonic power. This real - time monitoring and automatic adjustment mechanism ensures that the humidifier can automatically adjust the humidification amount according to the change of ambient humidity and maintain the stability of indoor humidity.

[0161] 2. High - efficient humidification performance

[0162] Ultrasonic Atomization and Airflow Distribution Control: The water in the lower water tank is atomized by the ultrasonic module, and the atomization rate is related to the driving frequency and power. At the same time, the air supply unit divides the airflow into two paths. One path passes through the humidifying film assembly for vertical permeation humidification and then discharges from the air outlet grille, and the other path enters the upper water vapor air duct, and forms a visual waterfall water mist through the arc-shaped air outlet of the suspension tower. This design enables the humidifier to increase the air humidity by using both ultrasonic atomization and humidifying film permeation methods at the same time, improving the humidification efficiency.

[0163] Visual Water Mist Enhancement: The arc-shaped air outlet design of the suspension tower enables the water mist to diffuse downward in a laminar flow state, and the coverage angle satisfies a specific formula. This design not only enhances the visual effect of the water mist, but also enables the water mist to diffuse more evenly into the air, improving the humidification effect.

[0164] 3. Safety and Energy Efficiency Optimization

[0165] Safety Protection Mechanism: When the water level in the upper water tank is lower than the minimum threshold or the lower water tank continuously atomizes for more than 30 minutes, the main control board triggers shutdown protection. This safety protection mechanism effectively prevents situations such as dry burning that may damage the equipment or cause safety accidents, and extends the service life of the equipment.

[0166] Energy Efficiency Optimization: By increasing the circumferential air outlet area of the air supply unit to enhance the effective contact area of the humidifying film assembly, the permeation efficiency of the humidifying film assembly is optimized. This design improves the energy utilization efficiency and reduces energy consumption while ensuring the humidification effect.

[0167] 4. User-Friendly Experience

[0168] Dynamic Adjustment and Comfort Enhancement: Dynamically adjust the flow ratio of the humidifying film assembly through the PID algorithm, and automatically adjust the humidification amount according to the environmental humidity difference to ensure the comfort of the indoor humidity. At the same time, the design of the visual waterfall water mist not only has a humidifying function, but also increases the ornamental value of the product, enhancing the user experience.

[0169] Maintenance Reminder and Ease of Use: When the permeation efficiency of the humidifying film assembly decreases to a certain extent, the system can trigger a maintenance reminder to prompt the user to clean or replace the humidifying film in time, ensuring the long-term efficient operation of the humidifier and improving the ease of use of the product.

[0170] 5. Superior Comprehensive Performance

[0171] Collaborative Humidification Mode: Utilize the collaborative humidification mode combining ultrasonic atomization and humidifying film permeation, and the total humidification amount is the sum of the humidification amounts of the two. This mode gives full play to the advantages of the two humidification methods, achieves efficient and uniform humidification effects, and meets the humidification requirements in different environments.

[0172] Strong adaptability: This control method can adapt to different environmental conditions and user needs. Through real-time monitoring and automatic adjustment, it ensures the stable operation and good performance of the humidifier in various situations.

[0173] 6. Multi-dimensional environmental adaptability

[0174] Integrate PM2.5 parameter: By introducing the air quality index (PM2.5), dynamically reduce the airflow ratio (α) of the humidifying membrane, avoid the aggravation of particulate matter sedimentation caused by the diffusion of water mist in a high-pollution environment, and solve the pain point that traditional humidifiers ignore air health.

[0175] Temperature and humidity collaborative compensation: Automatically correct the non-linear influence of temperature on the permeation efficiency of the humidifying membrane (such as high temperature accelerating evaporation).

[0176] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
