The terms used in this specification are only for describing specific embodiments, not for limiting the present invention.

[0030] Reference Figure 1 and 2 An embodiment of the present invention provides an electronic atomization device, including a surface acoustic wave atomizer 3, a liquid supply core 10, an oil tank 11, a gas-sensitive sensor component 6 and a control component 7. The surface acoustic wave atomizer 3 is connected to the oil tank 11 through the liquid supply core 10. The liquid supply core 10 is used to transport the liquid matrix in the oil tank 11 to the surface acoustic wave atomizer 3. The gas-sensitive sensor component 6 and the surface acoustic wave atomizer 3 are both electrically connected to the control component 7. The gas-sensitive sensor component 6 is used to detect the air quality information of the surrounding environment. The control component 7 is used to generate a corresponding control signal according to the air quality information, so that the surface acoustic wave atomizer 3 atomizes the liquid matrix to generate an aerosol.

[0031] Specifically, the electronic atomization device of the embodiment of the present invention includes a surface acoustic wave atomizer 3, a liquid supply core 10, an oil tank 11, a gas-sensitive sensor component 6 and a control component 7. The liquid matrix in the oil tank 11 is transported to the surface acoustic wave atomizer 3 through the liquid supply core 10, and the surface acoustic wave atomizer 3 generates surface acoustic waves to atomize the liquid matrix provided by the liquid supply core 10, thereby reducing the particle diameter of the generated aerosol, improving the atomization degree of the liquid matrix, and avoiding clogging of the atomization device; air quality information can be obtained in real time through the gas-sensitive sensor component 6, and then the working state of the surface acoustic wave atomizer can be dynamically adjusted according to changes in air quality, thereby realizing automatic control of the liquid matrix atomization and release process, without the need for manual adjustment by the user, thereby improving the user experience.

[0032] Surface acoustic wave (SAW) is an elastic wave propagating along the surface of an object. It is a sound wave whose energy is concentrated on the surface of the earth and propagated by chance discovered by British physicist Rayleigh in the 1880s while studying seismic waves. When the surface acoustic wave enters the fluid, it will produce a complex fluid-solid coupling effect. When the input power of the surface acoustic wave is large enough, the fluid will completely lose balance and atomize to produce a monodisperse liquid spray with an average diameter of 5μm.

[0033] The embodiment of the present invention applies the surface acoustic wave atomization technology to the electronic atomization device, which can achieve a higher atomization degree during the atomization process, reduce the particle diameter of the aerosol, and at the same time, a smaller atomization cone angle will appear during the atomization process, thereby achieving a larger atomization height, so that the aerosol can be sprayed without aggregation, which can prevent the clogging of the device; since the frequency of the surface acoustic wave is in the megahertz level, which is two to three orders of magnitude higher than that of the ultrasonic atomizer, the feasibility of atomizing liquids with higher viscosity is greatly improved; when the surface acoustic wave atomizes organic aromatic liquids (liquid matrix), no Cavitation effect will not destroy the molecular structure inside the organic aromatic liquid, and can effectively avoid the atomization of harmful substances, thereby improving the safety of the electronic atomization device; the aerosol droplets produced by surface acoustic wave atomization are softer and smaller in size, and the aerosol inhaled by the user can diffuse deeper into the human body, thereby improving the user experience; in addition, a gas-sensitive sensor component 6 is provided in the embodiment of the present invention, which can adjust the atomization amount, atomization time, and the time interval between two adjacent atomizations of the liquid matrix by responding to changes in the gas concentration in the vehicle, thereby realizing automatic control of the atomization and release process of the liquid matrix.

[0034] In some optional embodiments, the electronic atomization device of the embodiment of the present invention can be a vehicle-mounted aromatherapy device, which can monitor the gas concentration of the air mixture in the vehicle in real time through the gas-sensitive sensor component 6, and different types of gas-sensitive sensor components have different response sensitivities to different gases. Taking harmful gases and oxygen in the air as an example, when the gas-sensitive sensor component 6 detects that the air in the vehicle contains harmful gases or the oxygen content is too low, the control component 7 controls the surface acoustic wave atomizer 3 to atomize the aromatherapy liquid matrix, and the generated aromatherapy aerosol is sprayed and diffused into the cab, and the air is purified by reacting with harmful gases, and oxygen is generated, which increases the oxygen concentration in the vehicle, reduces harmful gases, and reduces the driver's fatigue and makes the driver more focused.

[0035] In some optional embodiments, the gas-sensitive sensor assembly may be a gas-sensitive sensor for different gases, or may be a sensor array formed by a plurality of gas-sensitive sensors for different gases.

[0036] Reference Figure 3 Further as an optional embodiment, the surface acoustic wave atomizer 3 includes a piezoelectric substrate 301 and a plurality of pairs of interdigitated electrodes 302, the interdigitated electrodes 302 are arranged on the piezoelectric substrate 301, and the two pairs of interdigitated electrodes 302 are arranged opposite to each other, and the interdigitated electrodes 302 are electrically connected to the control component 7, and are used to generate surface acoustic waves propagating along the upper surface of the piezoelectric substrate 301 under the control of the control component 7.

[0037] Specifically, the surface acoustic wave atomizer 3 is used to generate surface acoustic waves that can atomize the liquid matrix, such as Figure 3 As shown, the surface acoustic wave atomizer 3 can be composed of a piezoelectric substrate 301 and two interdigital electrodes 302, the interdigital electrodes 302 are deposited on the surface of the piezoelectric substrate 301 using a photolithography process, and pins are reserved at both ends of the interdigital electrodes 302, which are electrically connected to the control component 7 through wires. When the sinusoidal electrical signal of a specific frequency generated by the control component 7 acts on the surface acoustic wave atomizer 3, its interdigital electrodes 302 will produce a resonant response after being excited by the sinusoidal electrical signal, and a stable surface acoustic wave capable of atomizing the liquid is generated between the two interdigital electrodes 302 and propagates along the piezoelectric substrate 301, so that the liquid matrix delivered to the surface of the piezoelectric substrate 301 can be atomized. Compared with traditional atomizer sheets and micro-mesh ultrasonic atomizer sheets, the surface acoustic wave atomizer 3 of the present invention can atomize the liquid at a lower driving power, and the atomization effect is better than that of traditional atomizer sheets and micro-mesh ultrasonic atomizer sheets.

[0038] In the in-vehicle aromatherapy scenario, since the essential oils used to achieve the aromatherapy effect are organic aromatic liquids, the use of ultrasonic atomization technology will destroy the molecular structure of the organic aromatic liquid due to cavitation, and the aromatherapy aerosol produced by atomization may contain harmful substances. However, when the embodiment of the present invention uses surface acoustic waves to atomize the organic aromatic liquid, cavitation will not occur, so the internal molecular structure will not be destroyed, which can effectively avoid the atomization of harmful substances and improve the safety performance of the in-vehicle aromatherapy device.

The gas sensor component 6 is used to detect the air quality information of the environment around the electronic atomization device, that is, the air quality information in the car, and feed the air quality information back to the control component 7 disposed in the housing 5.

[0046] It can be understood that there can be multiple pairs of interdigitated electrodes 302 in the embodiment of the present invention, and a through hole 303 can be set between each pair of interdigitated electrodes 302. The other end of the liquid supply core 10 can extend multiple branches, which pass through the piezoelectric substrate 301 from each through hole 303 respectively to provide liquid matrix for the corresponding two interdigitated electrodes 302.

[0057] The above is a description of the system structure of the embodiment of the present invention. The working principle and workflow of the embodiment of the present invention will be further described below in conjunction with the control method.

[0058] Reference Figure 4 The embodiment of the present invention provides a control method of an electronic atomization device, which is used to be executed by the above-mentioned electronic atomization device, and includes the following steps:

[0059] S101, obtaining air quality information of the surrounding environment in real time through a gas-sensitive sensor component, where the air quality information includes at least one of a concentration of harmful gases and an oxygen content;

[0060] S102, when the concentration of harmful gas is greater than or equal to a preset first threshold value and / or the oxygen content is less than or equal to a preset second threshold value, a sinusoidal electrical signal is generated by a control component, and the sinusoidal electrical signal is sent to a surface acoustic wave atomizer;

[0061] S103, generating corresponding surface acoustic waves according to the sinusoidal electrical signal through a surface acoustic wave atomizer, so that the liquid matrix generates aerosol under the action of the surface acoustic wave.

[0062] Specifically, when the gas-sensitive sensor component detects that the concentration of harmful gases in the air in the vehicle is greater than or equal to the first threshold value and / or the oxygen content is less than or equal to the second threshold value, the control component generates a sinusoidal electrical signal of a specific frequency, which acts on the surface acoustic wave atomizer, wherein the interdigital electrodes will produce an inverse piezoelectric effect and a resonant response after being excited by the sinusoidal electrical signal, converting electrical energy into acoustic energy, and generating a stable surface acoustic wave that can atomize essential oil between the two interdigital electrodes. The surface acoustic wave propagates along the upper surface of the piezoelectric substrate, and when it propagates to the through hole, the liquid matrix on the liquid supply core is atomized. During the atomization process, a smaller atomization cone angle will appear, thereby achieving a larger atomization height, so that the aerosol is ejected from the exhaust port on the cover plate without aggregation, and there will be no clogging of the device, and the aerosol is fully diffused in the cab in a short time, and reacts with the harmful gas after contacting it to achieve air purification, and produces oxygen, thereby increasing the oxygen concentration in the vehicle, reducing harmful gases, and reducing driver fatigue and focusing more.

[0063] As an optional implementation, the control method further includes the following steps:

[0064] The frequency, amplitude and signal release interval of the sinusoidal electric signal are adjusted according to the change rate of the harmful gas concentration and / or the change rate of the oxygen content, thereby adjusting the atomization rate and atomization time interval of the liquid matrix.

[0065] Specifically, in the embodiment of the present invention, the frequency, amplitude, signal release interval and other parameters of the sinusoidal electrical signal can be adjusted according to the rate of change of the concentration of harmful gases and / or the rate of change of the oxygen content, and the adjusted sinusoidal electrical signal can act on the surface acoustic wave atomizer to change the atomization rate of the liquid matrix and the time interval between two adjacent atomizations. For example, when the rate of change of the concentration of harmful gases is positive (indicating that the harmful gases are gradually increasing) and / or the rate of change of the oxygen content is negative (indicating that the oxygen is gradually decreasing), the frequency and amplitude of the sinusoidal electrical signal can be appropriately increased, and the signal release interval of the sinusoidal electrical signal can be reduced, thereby increasing the atomization rate of the liquid matrix and reducing the atomization time interval, so as to quickly improve the air environment in the car; for another example, when the rate of change of the concentration of harmful gases is negative (indicating that the harmful gases are gradually decreasing) and / or the rate of change of the oxygen content is positive (indicating that the oxygen is gradually increasing), the frequency and amplitude of the sinusoidal electrical signal can be appropriately reduced, and the signal release interval of the sinusoidal electrical signal can be increased, thereby reducing the atomization rate of the liquid matrix and increasing the atomization time interval, thereby reducing the consumption of the liquid matrix and avoiding waste.
