[0030] This embodiment provides a gas atomization control system. Figure 1This is a schematic diagram of a gas atomization control system according to an embodiment of this application, as shown below. Figure 1 As shown, the system includes:
[0031] A gas device 102, located within the seat back 114, is used to output the target gas. A liquid device 104, located in the shoulder area 112, is used to output the target liquid. An atomizing device 106, located within the seat back, has its gas inlet and outlet connected via pipes, and its liquid inlet and outlet connected via pipes. The atomizing device generates an atomized medium based on the target gas and liquid. A spray device 108, located on the seat headrest 110, is connected to the outlet of the atomizing device via a pipe and is used to spray the atomized medium to form a target aerosol.
[0032] The aforementioned gas device is a modular component installed inside the seat back. Its core function is to generate and stably output the target gas used to drive the atomization process. The gas device consists of a gas generator and a gas storage unit working together. Through compression, filtration, and buffering mechanisms, it ensures that the output gas has constant pressure and purity to match the atomization device's requirements for airflow dynamics parameters, serving as the reliable power source for the entire atomization system.
[0033] The aforementioned seats are structural components within a vehicle used to support the occupants' bodies. They typically consist of a seat cushion, backrest, headrest, and support frame, and possess ergonomic support and comfort adjustment functions. In this embodiment, the seat serves as a carrier for an integrated gas atomization system. The rational layout of the seat's internal space accommodates gas devices, liquid devices, and piping systems, while ensuring that each functional unit maintains structural stability and operational safety during vehicle operation.
[0034] The aforementioned seat back is a vertical or inclined component in a seat that supports the occupant's back. Located behind the seat cushion, it is typically connected to the headrest and provides back support and posture adjustment. In this embodiment, the seat back serves as the main installation area for the gas device, atomizing device, and some control units. The improved internal structure of the seat back allows for reserved space for piping and equipment installation, achieving functional integration without affecting the original mechanical performance and occupant comfort of the seat.
[0035] In one optional embodiment, the gas device is located in the longitudinal central axis region of the seat back, and includes a gas generating device and a gas storage device. It is connected to an external gas source through a sealed pipeline and can continuously output a stable pressure and constant flow of air.
[0036] In another alternative embodiment, the gas device is integrated into a side cavity of the seat back. The gas device's inlet is connected to ambient air and has a built-in filter to remove particulate matter and moisture from the air, outputting clean and dry target gas. The gas device employs a modular gas path design and features adaptive pressure regulation, automatically adjusting output parameters according to load changes to achieve dynamic matching of airflow supply and energy efficiency improvement.
[0037] The gas device in this application embodiment ensures continuous power and balanced pressure during the atomization process by stably outputting the target gas, effectively improving the uniformity and controllability of the atomization medium and avoiding spray interruption or abnormal droplet size caused by air pressure fluctuations.
[0038] The aforementioned liquid storage device is located on the shoulder area of the seat and is specifically designed to store and controllably dispense the target liquid. The liquid storage device is connected to the atomizing device via tubing to ensure a stable, on-demand supply of the target liquid.
[0039] The aforementioned shoulder area of the seat refers to the local structural area above the seat back that corresponds to the occupant's shoulder and neck region. It is typically located below the headrest and above the middle of the backrest, serving as a support area where the scapula naturally rests in a seated posture. In this embodiment, the shoulder area of the seat is a functional mounting area for accommodating components such as liquid containers.
[0040] In one alternative embodiment, the liquid device includes a liquid storage device and a liquid replenishment device. The liquid storage device is located in the shoulder area of the seat, and its outlet is connected to an atomizing device via a pipeline. It relies on the gravity of the target liquid to achieve continuous, low-resistance liquid supply, maintaining the basic flow rate requirement without external power intervention. The structure is simple and has no electrical components, thus improving system reliability.
[0041] In another alternative embodiment, the liquid device consists of a liquid storage device and a micro pressure auxiliary pump. The liquid storage device is fixed to the shoulder of the seat, and the pressure auxiliary pump is activated when the atomizing device detects insufficient liquid supply. The pump pushes the target liquid into the atomizing device through controllable pressure to achieve dynamic liquid replenishment, adapt to high-frequency atomization requirements, and enhance the system's responsiveness to fluctuations in liquid consumption.
[0042] The liquid device in this embodiment is positioned on the shoulder of the seat to achieve stable output and convenient replacement of the target liquid, ensuring continuous and uninterrupted liquid supply during the atomization process, and improving system stability and user experience.
[0043] The aforementioned atomizing device is the core functional component of this system, located inside the seat back. Its function is to physically mix the target gas from the gas unit and the target liquid from the liquid unit, transforming them into a fine, uniform atomized medium. Internally, the atomizing device utilizes a gas-liquid dynamic synergy mechanism, leveraging the negative pressure effect or energy conversion structure generated when gas flows at high speed through a specific channel to achieve the dispersion and microparticle atomization of the target liquid. It achieves highly efficient atomization without mechanical stirring or an external heat source, serving as a crucial link between the gas source and the spray output.
[0044] The gas inlet end of the aforementioned atomizing device is the interface part on the atomizing device used to receive the target gas from the gas device. The gas inlet structure design ensures that the airflow enters the interior of the atomizing device in a predetermined direction and at a predetermined speed. It is the initial channel for realizing gas-liquid energy transfer and must have good sealing performance and fluid compatibility to avoid gas leakage or turbulence interfering with atomization efficiency.
[0045] The gas outlet of the aforementioned gas device is the terminal interface used to output the target gas, and it is connected to the gas inlet of the atomizing device via a pipeline. The function of the gas outlet is to safely and stably deliver the pressure-stabilized and filtered gas to the downstream atomizing unit, ensuring continuous gas supply and pressure consistency, and providing a reliable power source for the atomization process.
[0046] The aforementioned piping serves as flexible or rigid transmission channels connecting various functional modules, used to conduct target gas or liquid between gas, liquid, and atomizing devices. The piping material must be corrosion-resistant, pressure-resistant, and possess excellent sealing properties. Its smooth interior reduces flow resistance, ensuring leak-free and residue-free media transmission and maintaining the integrity and cleanliness of the overall system operation. All piping uses Teflon material, which offers excellent corrosion resistance and high-temperature resistance. The Teflon tubing from the atomizing device outlet to the spray device is insulated with self-regulating heating tape.
[0047] The liquid inlet end of the aforementioned atomizing device is a dedicated access point on the atomizing device for receiving the target liquid from the liquid source. The structure of the liquid inlet end of the atomizing device fits tightly with the end of the pipeline to achieve leak-free liquid introduction. It is typically located near the core atomization area, facilitating rapid mixing with the target gas under negative or pressure drive, and is a key liquid inlet channel for achieving efficient atomization.
[0048] The liquid outlet of the aforementioned liquid device is the terminal interface used to output the target liquid to the atomizing device. The design of the liquid outlet of the liquid device must be compatible with gravity or pressure-driven methods to ensure stable liquid output under conditions of no backflow and no dripping. The connection with the pipeline must have anti-misinsertion and sealing protection to improve the safety and maintainability of the gas atomization control system.
[0049] The aforementioned atomizing medium is a fine droplet suspension airflow formed by the physical interaction of the target gas and target liquid within the atomizing device. The atomizing medium has uniform particle size, good dispersibility, and controllable flowability and deposition characteristics. It serves as the functional carrier for subsequent spray outputs, capable of carrying therapeutic ingredients or skincare substances, enabling accurate and gentle application to specific areas of the occupant.
[0050] In one optional embodiment, the atomizing device includes a gas acceleration channel and a liquid storage structure. The target gas enters the gas acceleration channel through a pipeline and accelerates to form a negative pressure zone as it flows through the gas acceleration channel. The target liquid is introduced into the liquid storage structure through a pipeline by a liquid device. Under the negative pressure suction, it is drawn into the gas acceleration channel and mixed with the high-speed airflow to form a uniform atomizing medium. The structure is compact, has no moving parts, and has high reliability.
[0051] The aforementioned negative pressure zone is the power source for liquid intake and atomization. Without the need for a pump or mechanical parts, it can "inhale" the target liquid in the storage device into the high-speed airflow by relying solely on the airflow dynamics effect, thereby breaking down and dispersing the droplets and forming a uniform atomization medium.
[0052] In another alternative embodiment, the atomizing device is an integrated microfluidic atomizing chamber, which is equipped with a Venturi-type flow channel and a porous diffusion interface. The target gas and the target liquid enter from independent inlets, and laminar shearing and turbulent impact are achieved in the flow channel, so that the liquid is broken into micron-sized droplets under the action of airflow, forming a stable atomizing medium. This is suitable for application scenarios with high requirements for droplet size consistency.
[0053] The aforementioned Venturi-type flow channel is an asymmetric fluid channel structure with a converging section, a throat region, and a diverging section. The design of the Venturi-type flow channel is based on the Venturi effect, where the flow velocity increases and the static pressure decreases as the fluid flows through the throat region with the smallest cross-sectional area, creating a negative pressure suction zone. The Venturi-type flow channel structure enables automatic suction and efficient atomization of bypass liquids without external power. The gas acceleration channel in this embodiment adopts the Venturi-type flow channel structure.
[0054] The aforementioned porous diffusion interface is a solid-gas or liquid-gas interface with a microporous structure. Through multiple micropores distributed on the surface, it achieves uniform dispersion and directional release of fluids (such as atomizing media).
[0055] The atomizing device in this application embodiment achieves pump-free high-efficiency atomization through the synergistic effect of gas and liquid power. It has a simple structure, rapid response, ensures uniform particle size of the atomizing medium, stable output, and improves the fineness of the spray.
[0056] The aforementioned spray device is an end-output component installed on the seat headrest. Its function is to directionally spray the atomized medium from the atomizing device in a controllable manner, forming a target aerosol. The spray device's internal design incorporates flow channel shaping and outlet structure to ensure stable particle size and uniform distribution of the atomized medium during output, preventing liquid condensation or localized accumulation. It is a key component for achieving its intended function.
[0057] The headrest of the aforementioned seat is a component at the top of the seat back used to support the occupant's head, typically integrated with the backrest or adjustable. The structural design of the seat headrest must balance ergonomic support with spatial compatibility. In the proposed embodiment, the headrest serves as a mounting carrier for a spray device, with internal channels for connecting to the atomizing medium delivery pipeline, and an outer surface featuring a mist-emitting structure to ensure that the aerosol acts on the occupant's face or neck area without compromising comfort and safety.
[0058] The outlet end of the aforementioned atomizing device is the terminal interface used to output the generated atomized medium, and it is connected to the spraying device via a pipe. The structural design of the outlet end of the atomizing device ensures that the atomized medium flows out at a stable flow rate and in a uniform state, avoiding eddy backflow or droplet agglomeration. It is the only channel connecting the atomization core and the terminal output, directly affecting the formation quality and transmission efficiency of the aerosol.
[0059] The aforementioned target aerosol is a fine droplet suspended gas formed by the atomizing medium being released by a spraying device. It has controllable particle size, temperature and diffusion morphology, can carry functional components, and can achieve gentle and continuous application to local areas of the occupants.
[0060] In one optional embodiment, the spraying device is a porous micro-spray array integrated on the surface of the headrest. After the atomized medium is transported to the internal flow channel of the headrest through a pipeline, it is evenly released through multiple tiny spray holes. The spray hole angle is designed so that the mist diffuses in a fan shape, covering the face and neck area of the occupant, achieving gentle spraying. The structure is concealed and does not damage the appearance integrity of the headrest.
[0061] In another optional embodiment, the spray device adopts a single-sided duckbill-shaped mist outlet with an internal vortex guide cavity. After the atomizing medium enters, it forms a directional jet stream due to the expansion of the flow channel and the swirling effect. The sprayed mist is in the shape of a thin fan and is concentrated on the designated area. At the same time, the inner wall of the outlet is hydrophobically treated to effectively prevent droplet backflow or blockage, thereby improving output stability and long-term reliability.
[0062] The spray device of this application converts the atomizing medium into target aerosol, achieving uniform, directional, and drip-free output, improving user comfort and functional effectiveness, while ensuring cleanliness and stability during long-term operation through structural improvements.
[0063] In this embodiment, a gas device is disposed within the seat backrest of the seat for outputting the target gas; a liquid device is disposed within the shoulder area of the seat for outputting the target liquid; an atomizing device is disposed within the seat backrest, with its gas inlet and outlet connected via pipes, and its liquid inlet and outlet connected via pipes, for generating an atomized medium based on the target gas and target liquid; and a spray device is disposed on the headrest of the seat and connected to the outlet of the atomizing device via a pipe for spraying the atomized medium to form the target aerosol. This embodiment employs a method of independent gas and liquid distribution and gas-driven liquid atomization. By distributing the gas and liquid devices separately within the seat backrest and shoulder area, and coordinating their delivery via pipes to the atomizing device within the backrest, the negative pressure environment created by the target gas within the atomizing device achieves efficient atomization of the target liquid. This achieves the goal of stably generating the atomized medium without mechanical stirring or an external heat source, thereby realizing the technical effect of continuous and uniform output of the atomized medium, and solving the technical problem of poor gas atomization control in related technologies.
[0064] Optionally, the atomizing device further includes: a liquid storage structure, the liquid inlet end of which is connected to the liquid inlet end of the atomizing device, the liquid storage structure being used to store the target liquid; and a gas acceleration channel, the gas inlet end of which is connected to the gas inlet end of the atomizing device, the liquid inlet end of which is connected to the liquid outlet end of the liquid storage structure, the gas acceleration channel being used to accelerate the target gas to form a negative pressure, so as to draw in the target liquid and atomize the target liquid to obtain an atomizing medium.
[0065] The aforementioned liquid storage structure is a liquid temporary storage unit integrated inside the atomizing device. The liquid inlet end of the storage structure is connected to the external liquid input pipeline of the atomizing device, and is used to temporarily contain the target liquid delivered by the liquid device. Through structural sealing and position design, it is ensured that the liquid can remain stably without external force, providing a continuous and controllable liquid for the gas acceleration process.
[0066] The liquid inlet end of the aforementioned liquid storage structure is the initial interface for connecting to the external liquid delivery pipeline, used to receive the target liquid output from the liquid device. The structural design of the liquid inlet end of the liquid storage structure ensures that the liquid enters the liquid storage structure smoothly and without backflow, while also having anti-overflow and sealing functions to ensure that the liquid can remain stably when the system is stationary or running intermittently, providing a reliable liquid source for subsequent atomization.
[0067] The aforementioned gas acceleration channel is a flow channel structure within the atomizing device that has a contraction region, a throat region, and an expansion cross-section. The gas inlet end of the gas acceleration channel receives the target gas from the gas device, while the liquid inlet end of the gas acceleration channel is connected to the liquid storage structure. The gas is accelerated to a high speed in the flow channel, forming a negative pressure zone in the throat region, thereby actively drawing in the target liquid from the liquid storage structure and achieving liquid vaporization in the mixing section, thus completing the efficient atomization process.
[0068] The gas inlet end of the aforementioned gas acceleration channel is the starting point for the target gas to enter the acceleration flow channel, and it is connected to the outlet end of the gas device via a pipeline. The cross-sectional dimensions of the gas inlet end of the gas acceleration channel are matched with the airflow characteristics to ensure that the gas enters the channel in a uniform, low-turbulence state, providing the basic dynamic conditions for the subsequent formation of a stable high-speed airflow and a negative pressure region in the throat region.
[0069] The liquid inlet end of the aforementioned gas acceleration channel is the access point where the target liquid in the liquid storage structure is drawn into the gas flow, typically located near the throat region of the gas flow channel. The position of the liquid inlet end of the gas acceleration channel precisely corresponds to the gas flow velocity gradient, allowing the liquid to be accurately drawn in under negative pressure and immediately enter the high-speed gas flow, achieving instantaneous droplet breakup and atomization, and serving as a key coupling interface for gas-liquid mixing.
[0070] The liquid outlet end of the aforementioned liquid storage structure is the only outlet through which the liquid flows from the liquid storage unit to the gas acceleration channel. The structure of the liquid outlet end of the liquid storage structure is tightly connected to the liquid inlet end of the gas acceleration channel to ensure that the liquid flows out smoothly under the drive of gravity or pressure difference, avoiding the mixing of air bubbles or liquid stagnation, and maintaining the continuity and consistency of the atomization process.
[0071] The aforementioned negative pressure refers to the state where the static pressure in the throat region of the gas acceleration channel is lower than the ambient pressure due to the rapid increase in airflow velocity. This pressure difference drives the target liquid in the storage structure to be actively drawn into the airflow, which is the physical basis for achieving pump-free self-priming atomization. The intensity of the negative pressure is proportional to the square of the airflow velocity, directly determining the atomization efficiency and the uniformity of the medium.
[0072] In one optional embodiment, the gas acceleration channel adopts an integrally formed tapered flow channel with a smooth inner wall and accurate alignment with the outlet of the liquid storage structure. After entering the gas acceleration channel, the target gas is accelerated through the contraction section, forming a low static pressure zone in the throat region. The target liquid in the liquid storage structure is drawn into the throat region due to the pressure difference, and is instantly dispersed into droplets after violent shearing with the high-speed airflow, forming a uniform atomized medium.
[0073] This application embodiment achieves pump-free self-priming atomization through the coordinated operation of a liquid storage structure and a gas acceleration channel. The structure is simplified, the response is rapid, the atomization efficiency is high and the stability is strong, effectively reducing the power consumption and failure risk of the gas-free control system.
[0074] Optionally, the system also includes: a temperature sensor for monitoring the temperature of the target aerosol; a control system connected to the temperature sensor for generating temperature control parameters based on the difference between the current temperature and a preset temperature; and a heating structure installed on the liquid storage structure and the gas acceleration channel, connected to the control system, for heating according to the temperature control parameters.
[0075] The aforementioned temperature sensor is a sensing element used to perceive the temperature of the target aerosol in real time. Installed near the output path of the aerosol medium, it converts temperature changes into electrical signals and transmits them to the control system. The temperature sensor boasts fast response and high stability, making it a core sensing component for achieving closed-loop temperature control and ensuring that the output aerosol temperature meets preset requirements.
[0076] The aforementioned control system is an intelligent unit that receives temperature sensor signals and executes decisions. Based on the deviation between the measured temperature and the preset temperature, the control system calculates precise temperature control parameters through algorithms, outputs them to the heating structure, achieves dynamic adjustment, and possesses anti-interference capabilities and adaptive characteristics, ensuring that the system maintains stable temperature under different operating conditions.
[0077] The aforementioned difference in preset temperature refers to the numerical deviation between the actual temperature of the target mist monitored by the temperature sensor and the temperature preset by the control system. This numerical deviation serves as the feedback basis for temperature control, reflecting the degree of deviation between the current output state and the target state. It is a key input signal for the control system to determine whether heating adjustment is necessary.
[0078] The aforementioned temperature control parameters are dynamic adjustment commands generated by the control system through algorithmic calculations based on the preset temperature difference. These commands are used to control the output power or on / off timing of the heating structure. The temperature control parameter values are dynamically adjusted according to the magnitude of the temperature difference, the rate of change, and the system's thermal inertia to ensure precise and smooth heating behavior, achieving stable temperature convergence and continuous maintenance.
[0079] The aforementioned heating structure is a heat energy output unit arranged on the surface of the liquid storage structure and the gas acceleration channel. It is electrically connected to the control system and adjusts the heating power according to the output temperature control parameters to controllably preheat the target liquid and gas, improve atomization efficiency and prevent condensation. The heating structure has uniform heat distribution, rapid response and does not affect the structural sealing and material durability.
[0080] In one optional embodiment, a temperature sensor collects the temperature signal of the atomizing medium before output and transmits it to the control system. The control system compares the current value with the target value and outputs an incremental heating command. The heating structure simultaneously applies accurate heat energy to the outer wall of the liquid storage structure and the throat area of the gas acceleration channel, so that the liquid reaches a suitable temperature before entering the high-speed airflow, and the gas is also moderately preheated, thereby forming a stable atomized mist with uniform temperature at the moment of atomization.
[0081] The embodiments of this application achieve dynamic stability of aerosol temperature through a temperature control closed-loop system, improve atomization consistency and user comfort, prevent low-temperature condensation or overheating volatilization, and enhance functional reliability and safety.
[0082] Optionally, the gas device further includes: a gas generating device for generating high-pressure gas; and a gas storage device, wherein the gas inlet end of the gas storage device is connected to the gas generating device via a pipeline, and the gas outlet end of the gas storage device is connected to the gas outlet end of the gas device. The gas storage device is used to stabilize the high-pressure gas to obtain the target gas.
[0083] The aforementioned gas generating device is a power unit used to generate high-pressure gas in the embodiments of this application. The gas generating device compresses ambient gas to a level higher than atmospheric pressure through mechanical or electronic means, providing the necessary kinetic energy for the subsequent atomization process. The structure of the gas generating device must possess stable output capability and low-noise operation characteristics to ensure continuous and reliable operation in the vehicle operating environment; it is the starting link in the gas supply chain.
[0084] The aforementioned gas storage device is a buffer and pressure stabilizing unit connecting the gas generator and the downstream atomization system. The gas inlet of the gas storage device receives high-pressure gas from the gas generator, while the gas outlet outputs a stable target gas to the atomization device. Through the energy storage and pressure fluctuation attenuation of its internal volume, the gas storage device effectively eliminates pulsating interference during the operation of the gas generator, achieving stable gas pressure output and improving the consistency and controllability of the atomization process.
[0085] In one optional embodiment, the gas generator continuously generates fluctuating high-pressure gas, which is then input into the internal chamber of the gas storage device via a pipeline. The gas storage device absorbs pressure pulses using its internal gas capacity characteristics, causing the output gas pressure to become more gradual. The stable target gas then flows continuously to the atomizing device through the gas outlet of the gas device, achieving a smooth transition from intermittent high-pressure output to continuous stable pressure supply, ensuring that the atomization process is not affected by fluctuations in the gas source.
[0086] The gas storage device in this application embodiment effectively filters pressure fluctuations in the gas generating device, achieves stable output of the target gas, improves the consistency of the atomizing medium and the reliability of system operation, and reduces the risk of atomization failure caused by unstable gas pressure.
[0087] Optionally, the gas generating device further includes: an air inlet for connecting to the external environment to introduce initial air; a filter device, the gas inlet of which is connected to the air inlet, for filtering the initial air to obtain filtered gas; and a high-pressure diaphragm pump, the gas inlet of which is connected to the gas outlet of the filter device, and the gas outlet of which is connected to the gas inlet of the gas storage device, for pressurizing the filtered gas to generate high-pressure gas.
[0088] The aforementioned air intake is an opening structure that connects the gas generating device to the external environment, used to introduce ambient air as the initial gas source. The design of the air intake must balance flow capacity and dust protection to ensure that sufficient gas can be continuously and stably drawn in even in a closed or dynamic driving environment. It is the starting inlet of the entire gas circuit system.
[0089] The aforementioned filtration device is a purification unit connected in series between the air inlet and the high-pressure diaphragm pump. The gas inlet of the filtration device is connected to the air inlet and is used to remove dust, particulate matter, and impurities contained in the initial air, outputting clean filtered gas, preventing contaminants from entering subsequent precision components, extending equipment life, and ensuring the purity and safety of the atomizing medium.
[0090] The aforementioned high-pressure diaphragm pump is an oil-free pump body that compresses gas through the reciprocating motion of a diaphragm. The gas inlet of the high-pressure diaphragm pump is connected to the outlet of the filter device, and the gas outlet is connected to the gas storage device. It is used to pressurize the filtered gas to the required high pressure level. It has characteristics such as fast response, low vibration, and corrosion resistance, and is the actuator for gas pressurization.
[0091] In one optional embodiment, ambient air is introduced through the air inlet and first enters the filtration device. After passing through multiple layers of filter media to remove particles and impurities, filtered gas is formed. The filtered gas is then introduced into a high-pressure diaphragm pump, where it is periodically compressed and pressurized by the diaphragm before being output to the gas storage device. The entire airflow path is completely sealed throughout the process, effectively preventing contamination and leakage, and ensuring that the gas entering the atomization system is clean, stable, and has reliable pressure.
[0092] This application embodiment achieves efficient purification and stable pressurization of ambient air through the coordinated action of the air inlet, filter device and high-pressure diaphragm pump, ensuring the purity and pressure consistency of the target gas, and improving system reliability and long-term operational safety.
[0093] Optionally, the liquid device further includes: a liquid storage device for storing the target liquid; and a liquid replenishment device, wherein the liquid inlet of the liquid replenishment device is connected to the liquid storage device via a pipeline, and the liquid outlet of the liquid replenishment device is connected to the liquid inlet of the atomizing device, for inputting the target liquid into the atomizing device.
[0094] The aforementioned liquid storage device is a sealed container used to hold the target liquid for extended periods. Its structural design facilitates installation, replacement, and maintenance. The liquid inlet of the storage device is connected to a replenishment device, serving as the initial storage unit for the target liquid. This ensures the liquid remains stable, leak-free, and evaporation-free when not in operation, providing a continuous and reliable liquid source for the atomization process.
[0095] The aforementioned replenishment device is a dynamic transmission module connecting the liquid storage device and the atomizing device. The liquid inlet of the replenishment device is connected to the liquid storage device, and the liquid outlet is connected to the liquid inlet of the atomizing device. It is responsible for delivering the target liquid to the atomizing area as needed during system operation, and has flow regulation capabilities and a response mechanism to ensure continuous, accurate, and uninterrupted liquid flow.
[0096] The liquid inlet of the aforementioned replenishment device is an interface connected to the storage device, used to receive the target liquid from the storage device. The structural design of the liquid inlet of the replenishment device ensures that the liquid flows into the replenishment device in a unidirectional, non-backflow manner, while also possessing sealing and anti-cavitation capabilities to prevent air from mixing in or liquid from leaking, providing a stable input source for subsequent accurate liquid infusion.
[0097] The liquid outlet of the aforementioned replenishment device is the delivery outlet from which the target liquid leaves the replenishment device and enters the atomizing device, and it is connected to the liquid inlet of the atomizing device via a pipeline. The position and flow channel design of the liquid outlet of the replenishment device must match the atomization requirements to ensure that the liquid is output smoothly in a controllable flow state, avoiding pulsation, dripping, or air bubble entrainment, and ensuring the continuity and uniformity of the atomization process.
[0098] In one optional embodiment, the target liquid is stored in a liquid storage device. If the atomizing device is activated and consumes the liquid, the replenishing device continuously draws the liquid from the liquid storage device through a pipeline and smoothly delivers it to the liquid inlet of the atomizing device by gravity or micro-pressure drive, thereby realizing the transition of the liquid from static storage to dynamic supply.
[0099] This application embodiment achieves stable storage and on-demand supply of the target liquid through the coordinated use of a liquid storage device and a liquid replenishment device, ensuring the continuity of the atomization process and improving the system's automation level and ease of use.
[0100] Optionally, the liquid replenishment device further includes: a gravity liquid replenishment device, used to input the target liquid into the atomizing device according to the gravity of the target liquid; and a pressure liquid replenishment device, used to control the input of the target liquid into the atomizing device when the liquid flow rate of the atomizing device is less than the preset flow rate.
[0101] The aforementioned gravity-feed liquid supply device is a liquid supply structure that relies on the gravity of the target liquid itself to achieve natural flow. Through the vertical arrangement of the high-level liquid storage and the low-level atomization inlet, the gravity-feed liquid supply device enables the liquid to be spontaneously transported downwards without external force. It has a simple structure, zero energy consumption, and is suitable for stable, low-flow liquid replenishment needs under normal operating conditions.
[0102] The gravity of the target liquid mentioned above refers to the downward force generated by the liquid under the influence of Earth's gravity. The magnitude of the gravity of the target liquid is determined by the liquid mass and gravitational acceleration. In this system, it serves as the driving force source for the gravity replenishment device. It can realize the natural flow of liquid from the high-level storage area to the low-level atomization inlet without external energy input. It is an energy-saving, reliable, and noiseless passive liquid supply mechanism. The stability and continuity of the gravity of the target liquid depend on the reasonable design of the liquid volume and the vertical height difference of the system.
[0103] The aforementioned pressure replenishment device is an auxiliary liquid supply unit with active pressurization capability. When the system detects that the liquid flow rate of the atomizing device is lower than the preset threshold, it automatically starts and applies controllable pressure to force the target liquid to be pushed to the atomizing device to compensate for the deficiency of gravity replenishment and ensure the continuity and reliability of liquid supply under high demand or non-ideal installation posture.
[0104] The aforementioned liquid flow rate refers to the volume or mass of liquid transported from the liquid device to the liquid inlet of the atomizing device per unit time during the operation of the atomizing device. The liquid flow rate is provided by gravity or pressure replenishment devices, and the actual value is collected in real time by a flow sensor to assess the stability of the liquid supply during the atomization process. Fluctuations in the liquid flow rate directly affect the concentration, particle size, and spray continuity of the atomizing medium, and are therefore a feedback parameter for achieving accurate control.
[0105] The aforementioned preset flow rate refers to the target liquid flow rate threshold set in advance to ensure stable operation of the atomizing device and the generation of qualified atomized media. The value of the preset flow rate is determined experimentally or through simulation based on the geometric parameters of the atomizing structure, gas velocity, and target aerosol characteristics, such as particle size, temperature, and spray volume. If the actual liquid flow rate is lower than the preset flow rate, the control system determines that the liquid supply is insufficient and triggers the pressure replenishment device to maintain the continuity and consistency of the atomization process. The preset flow rate serves as a reference value for the control system and is a setting parameter for achieving closed-loop intelligent replenishment and ensuring atomization quality.
[0106] In one optional embodiment, the target liquid flows naturally from the elevated storage structure into the atomizing device via a gravity-assisted replenishment device. If the atomization demand increases or the flow rate decreases due to increased flow resistance, the control system activates the pressure replenishment device, applying supplementary pressure to the pipeline through micro-pressure drive to restore the liquid flow rate to the set level. The two replenishment methods can be switched, and the entire process is autonomously judged and controlled by the system without manual intervention.
[0107] This application embodiment uses a gravity and pressure-based liquid replenishment mechanism to ensure basic liquid supply under low power consumption and automatically enhance output in case of abnormal operating conditions, thereby improving the stability of liquid supply and system adaptability, and avoiding atomization interruption or performance degradation.
[0108] Optionally, the system further includes: a flow sensor connected to the atomizing device for detecting the liquid flow rate of the atomizing device; and a control system connected to the flow sensor and the pressure replenishment device for generating pressure control parameters based on the difference between the received liquid flow rate and the preset flow rate when the received liquid flow rate is less than the preset flow rate, wherein the pressure replenishment device outputs the target liquid based on the pressure control parameters.
[0109] The aforementioned flow sensor is a detection element connected to the liquid passage of the atomizing device, used to monitor the flow rate or volume of the target liquid passing through the atomizing device in real time. The output signal of the flow sensor reflects the instantaneous state of the liquid supply, possessing high responsiveness and anti-interference capability, and is a key sensing unit for the system to achieve closed-loop flow control.
[0110] The aforementioned control system is an intelligent processing unit that receives signals from the flow sensor and executes decisions. The control system is electrically connected to the flow sensor and the pressure replenishment device. Based on the difference between the measured flow rate and the preset flow rate, it calculates and generates dynamic pressure control parameters through algorithms, precisely regulating the output intensity of the pressure replenishment device to achieve automatic correction and stable maintenance of the liquid supply.
[0111] The aforementioned pressure control parameters are command signals dynamically generated by the control system based on the flow deviation, used to adjust the driving pressure or operating timing of the pressure replenishment device. The values of the pressure control parameters change non-linearly with the magnitude of the flow deficit, ensuring accurate, smooth, and overshoot-free replenishment operations, achieving a closed-loop response from anomaly detection to intelligent compensation.
[0112] In one optional embodiment, when the atomizing device is operating, the flow sensor continuously collects data on the liquid flow and transmits it to the control system. If the flow rate is detected to be lower than the preset flow rate, the control system calculates the difference and generates corresponding pressure control parameters, driving the pressure replenishment device to inject the target liquid into the atomizing device at an appropriate pressure until the flow rate recovers to the set preset flow rate.
[0113] This application embodiment ensures a stable supply of atomized liquid through closed-loop control of flow feedback and pressure compensation, effectively avoiding atomization failure due to insufficient liquid supply and improving system reliability and functional consistency.
[0114] According to an embodiment of this application, an embodiment of a gas atomization control method is also provided. Figure 2 This is a flowchart of a gas atomization control method according to an embodiment of this application, such as... Figure 2 As shown, the method includes:
[0115] Step S202: In response to receiving a gas atomization command, control the gas device to generate the target gas.
[0116] The aforementioned gas atomization command is a control signal received by the control system to activate the atomization function. It can be triggered by the user interface, the vehicle network, or preset conditions. Essentially, the gas atomization command is a logic level or data frame instruction used to clearly inform the control system to execute the gas generation and atomization process, ensuring the function is activated as needed and preventing malfunctions.
[0117] In one optional embodiment, if the user sends a gas atomization command through the in-vehicle control interface, the control system responds immediately, activates the gas generating unit in the gas device, drives the gas device to start drawing in external air and compressing and purifying it, and then the gas storage structure stably outputs the target gas, establishing a gas source foundation for the atomization process.
[0118] In another optional embodiment, if the vehicle environment perception system determines that the occupant is in a seated state and meets the preset usage conditions, it triggers a gas atomization command, and the gas device is immediately started. Without manual intervention, the target gas is generated, stabilized, and output in sequence, realizing the intelligent and scenario-based autonomous activation of the function.
[0119] This application embodiment uses a command-driven precise start-up mechanism to ensure that the gas device operates only when needed, improving system energy efficiency and responsiveness, avoiding unnecessary energy consumption and misoperation, and ensuring the controllability and safety of the atomization process.
[0120] Step S204: Control the atomizing device to generate an atomizing medium based on the target gas and the target liquid stored in the liquid device.
[0121] In one optional embodiment, the target gas enters the gas acceleration channel of the atomizing device at a constant flow rate, forming a low-pressure zone in the throat region. At this time, the target liquid stored in the liquid device is drawn into the low-pressure zone and strongly mixed with the high-speed airflow. It is instantly cut into micron-sized droplets, forming a uniformly suspended atomizing medium, thus completing the morphological transformation from liquid to aerosol.
[0122] In another alternative embodiment, if the target gas is continuously input, the target liquid is stably supplied to the liquid storage structure of the atomizing device through the liquid replenishment device. When the gas flows through a specific geometric channel, the Venturi effect is generated, realizing pure hydrodynamic atomization without the intervention of mechanical parts, and generating a continuous, non-pulsating atomizing medium flow.
[0123] This application embodiment achieves a highly efficient and wear-free atomization process through the synergistic effect of the target gas and the target liquid, improving the uniformity of the medium particle size and the stability of the generation, and ensuring the fineness of the spray and the safety of use.
[0124] Step S206: Control the spraying device to spray out the atomizing medium to form the target aerosol.
[0125] In one optional embodiment, the gas atomization system dynamically adjusts the opening and closing sequence and degree of the spray outlet based on the temperature, pressure, and flow rate of the atomizing medium. If the atomizing medium is detected to have reached a stable state and the temperature is within the target range, the controller opens the solenoid valve and controls the opening frequency and duration of the nozzle using pulse width modulation, allowing the atomized mist to be released in an intermittent but continuous rhythm. If the medium parameters deviate from the set range, the gas atomization system automatically delays the spray or reduces the spray intensity until the system returns to stability, achieving intelligent spray control based on feedback.
[0126] In another optional embodiment, the gas atomization system controls the spray device to trigger an adaptive spray mode by sensing the user's head proximity and posture changes. If a user is detected within the spray's effective range, the control system activates the spray channel and, according to a preset area mapping algorithm, sequentially opens multiple nozzle units in a time-sharing manner, forming a spray path that gradually diffuses from the center outwards. If the user is detected moving out of the effective range, the gas atomization system automatically shuts off the spray. If the user remains within the effective range, the gas atomization system switches to a low-frequency maintenance mode, releasing only intermittent trace amounts of aerosol to maintain the effect.
[0127] The control strategy in this application implements accurate spray control logic that starts when someone is present, stops when no one is present, dynamically tracks, and outputs on demand.
[0128] The component structure of the product in this application embodiment includes: a gas device, a filter device, a gas storage device, an atomizing device, a heating structure, a temperature sensor, a liquid replenishment device, a liquid storage device, a spray outlet, pipelines, fixed components, and a fault alarm.
[0129] The gas device uses a high-pressure diaphragm pump, which has the ability to generate high-pressure gas and is the power core of the entire nebulization therapy system.
[0130] The filter is installed at the air inlet to filter the air entering the high-pressure diaphragm pump, ensuring air purity and preventing impurities from affecting subsequent atomization effects and equipment lifespan.
[0131] The gas storage device is used to store the gas generated by the diaphragm pump, thereby stabilizing the gas pressure.
[0132] Atomizing devices, with their specific flow channel structure, are key components for achieving liquid atomization. An atomizing device includes a liquid storage structure and a gas acceleration channel, used to store the liquid and accelerate gas flow to achieve atomization, respectively.
[0133] The heating structure uses thick-film heating elements in the liquid storage structure and gas acceleration channel of the atomizing device to heat the liquid and gas in order to control the temperature of the atomized gas.
[0134] A miniature negative temperature coefficient (NTC) thermistor is installed at the outlet of the atomizing device to monitor the temperature of the target mist at the outlet and feed the temperature signal back to the control system.
[0135] The liquid replenishment system consists of a gravity replenishment section and a pressure replenishment section. Gravity replenishment utilizes the liquid's own weight to replenish the Wuhai unit. The pressure replenishment section serves as an auxiliary system, activating when the flow sensor detects insufficient liquid supply to achieve accurate replenishment.
[0136] The liquid storage device uses a press-to-open mechanism similar to a ballpoint pen, allowing the replenishment device to be inserted and ejected easily for convenient liquid bottle replacement. When inserting, align the device with the slot and push it all the way in; it automatically locks and connects the liquid path. No rotation or tools are required, making it simple to operate and leak-proof.
[0137] The spray outlets are made on both sides of the front of the headrest. The nozzles are duckbill shaped and have an internal "vortex" structure. The surface of the nozzle pipes is treated with a hydrophobic and oleophobic nano-coating.
[0138] The piping is a single piece and can be made of Teflon, which has excellent corrosion resistance and high temperature resistance. The Teflon tubing from the atomizing device outlet to the nozzle is wrapped with self-regulating electric heating tape for insulation.
[0139] The fixed component is a high-pressure diaphragm pump located on the longitudinal center line of the car seat back. Above it, in sequence, are the air reservoir and the atomizing device. All three are bolted to the seat frame. Silicone shock-absorbing pads are used at the air pump mounting point to reduce vibration and abnormal noise. The fluid replenishment device is installed in the seat shoulder area.
[0140] The fault alarm is a fault detection and alarm system. If a fault occurs, such as a high-pressure diaphragm pump failure, filter blockage, or abnormal temperature, the system will display the corresponding problem on the large screen and propose corresponding measures, while simultaneously stopping the equipment operation.
[0141] The connection relationships between the components in this embodiment are as follows: the filter device and the air inlet of the high-pressure diaphragm pump are connected by threads or snaps to ensure a good seal and prevent air leakage. The air outlet of the high-pressure diaphragm pump is connected to the air inlet of the air storage device through a pipeline, and the connection is sealed with a sealing ring. The air outlet of the air storage device is connected to the gas inlet of the atomizing device through a pipeline. The liquid outlet of the liquid replenishment device is connected to the liquid inlet of the atomizing device through a pipeline. The outlet of the atomizing device is connected to the spray outlet on the front of the seat headrest through a pipeline. The signal line of the temperature sensor is connected to the control system to transmit the temperature signal to the control system. The signal line of the flow sensor is also connected to the control system for feedback on the liquid supply status. The control line of the pressure liquid replenishment device is connected to the control system, which controls the start and stop of the pressure liquid replenishment device.
[0142] The spatial relationship between the components in this embodiment is as follows: the high-pressure diaphragm pump, the gas storage device, and the atomizing device are arranged longitudinally on the car seat back, in a straight line, which facilitates pipeline connection and overall layout. The fluid replenishment device is installed on the seat shoulder, allowing the user to easily press in and eject the fluid reservoir. The spray outlets are located on both sides of the front of the headrest, enabling direct spraying of atomized gas towards the user's head area.
[0143] The specific coordination relationship between the components in this embodiment is as follows: the gas pressure generated by the high-pressure diaphragm pump must meet the power requirements of the subsequent atomizing device, while the gas storage device stabilizes the pressure, ensuring that the gas pressure entering the atomizing device remains within a suitable range. The liquid storage structure and gas acceleration channel of the atomizing device work in conjunction with the heating structure to heat the liquid and gas to achieve the set atomized gas temperature. A temperature sensor monitors the outlet temperature of the spray device and feeds the signal back to the control system. The control system adjusts the power of the heating structure based on the feedback signal, forming a proportional-integral-derivative (PID) closed-loop control to ensure that the outlet mist temperature of the spray device remains stable at 40±1℃. The gravity replenishment device and the pressure replenishment device work together. If the liquid is sufficient, gravity replenishment is used; if the flow sensor detects insufficient liquid supply, the piezoelectric micro-droplet pump is activated to replenish the liquid, ensuring a stable liquid supply to the atomizing device.
[0144] The working principle and operation process of this embodiment are as follows: During the startup phase, after the equipment is started, the high-pressure diaphragm pump begins to work, drawing in air from the air inlet. After the air is filtered through the filter device, high-pressure gas is generated. At the same time, the liquid replenishment device begins to replenish liquid to the liquid storage device of the atomizing device under the action of gravity.
[0145] During the gas storage and stabilization stage, the high-pressure gas generated by the high-pressure diaphragm pump enters the gas storage device, where it is stored and its pressure is stabilized to ensure that the gas pressure entering the atomizing device is stable.
[0146] During the atomization stage, gas at a stable pressure enters the atomizing device from a miniature gas storage tank. In the throat region of the gas acceleration channel of the atomizing device, the gas velocity increases and the pressure decreases, forming a negative pressure zone. At this time, the liquid in the liquid storage device of the atomizing device is drawn into the throat region under the action of negative pressure, mixes with the high-speed airflow, and achieves atomization.
[0147] During the temperature control phase, as the liquid and gas enter the atomizing device, the heating structure heats the liquid and gas in the storage structure and gas acceleration channel. A miniature NTC thermistor monitors the atomization temperature at the outlet of the atomizing device in real time and feeds the temperature signal back to the control system. Based on the feedback signal, the control system adjusts the power of the thick-film heating element to form a PID closed-loop control, stabilizing the outlet atomization temperature at a preset temperature, for example, 40±1℃, which can be adjusted according to actual conditions.
[0148] During the replenishment phase, if the liquid storage device has sufficient liquid, it continuously replenishes the atomizing device using gravity. If the flow sensor detects insufficient liquid supply, the control system sends a signal to activate the pressure replenishment device, accurately replenishing the liquid storage structure of the atomizing device to ensure that the atomization process is not affected.
[0149] During the spraying phase, the atomized and temperature-controlled gas is delivered through pipelines to the spray outlet on the front of the headrest. Due to the duckbill-shaped nozzle and its internal "vortex" structure, the gas forms a specific spray pattern at the nozzle and is sprayed towards the user's head area. At the same time, a self-regulating heating cable wraps and insulates the pipeline from the outlet of the atomizing device to the nozzle, preventing the gas temperature from dropping during transportation.
[0150] During the shutdown delay phase, the user turns off the function, the heating is turned off, the air pump runs at full power for 30 seconds to remove residual liquid in the pipe, and at the same time the piezoelectric micro-droplet pump draws in the opposite direction to prevent further dripping.
[0151] In a specific implementation scenario, the equipment can be started first by connecting the vehicle's 13.5V DC power supply to begin the high-pressure diaphragm pump. Simultaneously, the filter device will activate to ensure the purity of the air entering the pump. The aforementioned voltage is the vehicle's 13.5V DC power supply, ensuring the high-pressure diaphragm pump can start normally and generate at least 0.3 MPa pressure. For gas storage and stabilization, the gas generated by the high-pressure diaphragm pump enters a gas storage device, where its pressure is stored and stabilized. The storage device has a capacity of 10 ml, sufficient to meet the requirement for stable gas pressure.
[0152] Liquid atomization involves a gas at stable pressure entering the atomizing device from a gas storage device, where it mixes with the liquid entering the liquid storage structure of the atomizing device under gravity, thus achieving atomization. The atomizing device is precision-manufactured using Micro-Electro-Mechanical Systems (MEMS) technology to ensure accurate flow channel structure and achieve highly efficient atomization.
[0153] Temperature control is achieved through a thick-film heating element that heats the liquid storage structure and gas acceleration channel of the atomizing device. A miniature NTC thermistor monitors the outlet mist temperature and feeds the signal back to the control system. The control system adjusts the heating power using PID closed-loop control to stabilize the outlet mist temperature at 40±1℃. The thick-film heating element provides rapid and uniform heating. The miniature NTC thermistor offers high accuracy and fast response. The control system employs a PID control algorithm to achieve precise temperature control.
[0154] Liquid replenishment control: If the liquid storage device has sufficient liquid, gravity replenishment is used to supplement the liquid to the atomizing device. If the flow sensor detects insufficient liquid supply, the control system activates the pressure replenishment device to replenish the liquid.
[0155] The spray output system delivers atomized and temperature-controlled gas through pipelines to the spray outlet, forming a specific spray pattern. The pipelines are made of Teflon, offering excellent corrosion resistance and high-temperature resistance. The nozzle is duckbill-shaped with an internal "vortex" structure to create the ideal spray pattern. The nozzle and pipeline surfaces are treated with a hydrophobic and oleophobic nano-coating to prevent liquid residue and clogging. A self-regulating heating cable wraps around the pipeline for insulation, ensuring stable gas temperature during transport.
[0156] After the shutdown is delayed and the gas atomization function stops, the heating is turned off, and the gas is blown out at full power to remove the liquid material inside the pipe.
[0157] The vehicle infotainment system is connected to the vehicle network via the Controller Area Network (CAN) bus and the Local Interconnect Network (LIN) bus, allowing control of functions such as turning on / off and adjusting settings on the vehicle's large screen.
[0158] Figure 3 This is a schematic diagram of a seat gas atomizing device according to an embodiment of this application, as shown below. Figure 3 As shown, the device includes: headrest assembly 302, pipeline 304, liquid replenishment device 306, atomizing device 308, air storage device 310, filter device 312, seat assembly 314, and high-pressure diaphragm pump 316.
[0159] The seat gas atomizing device uses the seat assembly 314 as the mounting carrier. A high-pressure diaphragm pump 316 is fixed inside the seat back, and its air inlet is connected to a filter device 312 to purify the inhaled air and compress it to output high-pressure gas. The high-pressure gas is transported to the gas storage device 310 via pipeline 304 to achieve pressure stabilization and pulse buffering. The stabilized gas continues to be transported to the gas inlet of the atomizing device 308 via pipeline 304, serving as the atomization power source. At the same time, a liquid replenishment device 306 is installed in the shoulder area of the seat, and its liquid outlet is connected to the liquid inlet of the atomizing device 308 via an independent pipeline 304 to provide the target liquid for the atomization process. Inside the atomizing device 308, the gas and liquid are mixed and atomized through a gas acceleration structure. The resulting atomized medium is transported to the headrest assembly 302 via another pipeline 304, and finally sprayed out from the headrest surface to form the target aerosol. Each component forms a closed-loop gas-liquid passage through pipeline 304. The filter device 312 ensures the cleanliness of the gas source, the gas storage device 310 stabilizes the gas pressure, the liquid replenishment device 306 ensures continuous liquid supply, the atomizing device 308 realizes the core atomization function, and the headrest assembly 302 completes the final output. The components are spatially divided into areas and functionally closely coordinated to form a gas atomization system integrated inside the seat and operating independently.
[0160] Figure 4 This is a schematic diagram of the control logic of a gas atomization control system according to an embodiment of this application, as shown below. Figure 4 As shown, the control module includes the seat system. The backrest internal atomization assembly module includes a flow sensor, a thick-film heating element, a high-pressure diaphragm pump, an air storage device, a liquid storage device, a miniature negative temperature coefficient sensor, an atomizing device, a heat-tracing and insulation pipeline, and a spray device. The seat system controls the thick-film heating element and the high-pressure diaphragm pump. The user controls the seat system through the vehicle's central control screen. The central control screen transmits control signals to the seat system, and the seat system returns information to the central control screen. The seat system controls the high-pressure diaphragm pump, which sends pulses to the air storage device, which then sends the target gas to the atomizing device. Simultaneously, the liquid storage device sends the target liquid to the atomizing device. The atomizing device sends the atomized medium to the spray device through the heat-tracing and insulation pipeline. The seat system reads information from the flow sensor and controls the liquid storage device to replenish the liquid. The seat system reads data from the miniature negative temperature coefficient sensor to further control the thick-film heating element to maintain a constant temperature in the atomizing device.
[0161] Figure 5 This is a schematic diagram of an atomizing device according to an embodiment of this application, such as... Figure 5As shown, the atomizing device 506 includes a liquid storage structure 502 and a gas acceleration channel 504. The liquid storage structure 502 is used to stably store the target liquid to be atomized and is connected to the liquid inlet of the gas acceleration channel 504 through its outlet end, providing a continuous and controllable liquid for the atomization process. The gas acceleration channel, through its internal contraction-expansion flow channel design, causes the target gas from the gas device to accelerate its flow and experience a sudden pressure drop when passing through the throat region, forming a negative pressure zone. This negative pressure effect is used to actively draw in the target liquid from the liquid storage structure and achieve efficient atomization. The liquid storage structure and the gas acceleration channel constitute a synergistic atomization unit. The liquid storage structure ensures a stable supply and pre-storage of the liquid, while the gas acceleration channel converts the liquid into fine droplets through gas dynamics principles. The atomization effect directly depends on the continuity of the liquid supply in the liquid storage structure and the matching relationship between the airflow velocity and the negative pressure intensity in the gas acceleration channel, together achieving passive and efficient atomization without the assistance of a mechanical pump.
