Due to energy limitations, it is difficult to directly atomize the aerosol atomization matrix into particles below 10μm (the atomized particles are usually between 50-200μm), so it is difficult to achieve the effect of direct inhalation by users; in order to achieve the inhalable effect, a secondary atomization system is added. The relevant secondary atomization system is equipped with a heater to heat the airflow ejected from the nozzle, but the relevant performance needs to be optimized.

[0030] The embodiments of the present invention provide a nebulizer and a nebulizing device. Among them, the nebulizer is a device that vaporizes an aerosol atomizing matrix into a gas or cuts it into a number of tiny droplets to form a mist medium. The nebulizer includes an atomizing nozzle, which is an injection component used in the nebulizer. The atomizing nozzle can atomize the aerosol atomizing matrix to be atomized, thereby forming atomized droplet particles and spraying them out of the atomizing nozzle. The nebulizer can be applied to various atomization scenarios. For example, the nebulizer can be applied to atomization scenarios such as medical beauty and daily life. The aerosol atomizing matrix to be atomized can be a medicine liquid, a perfume, and an aerosol matrix that can produce a special smell, etc. Those skilled in the art can understand that there can be many application scenarios for the nebulizer, and the embodiments of the present invention do not limit the application scenarios of the nebulizer.

[0031] The heating technology of porous ceramics or porous cotton is the mainstream way to realize electronic atomization technology. The aerosol atomization matrix to be atomized is directly infiltrated into the porous ceramics / porous cotton, or the porous ceramics or porous cotton is immersed in the aerosol atomization matrix, and the aerosol atomization matrix is ​​atomized by high-temperature heating of the resistance wire / membrane in the porous ceramics or porous cotton. In order to avoid the health problems such as taste problems and heavy metal toxicity problems caused by high-temperature heating electronic atomization technology, low-temperature atomization technology has become an increasingly important research focus, among which the atomization nozzle based on high-speed airflow is one of the ideal solutions.

[0032] For example, a gas-liquid two-phase flow atomizing nozzle has an airflow channel and an aerosol atomizing matrix channel arranged inside. The gas and the aerosol atomizing matrix to be atomized enter the nozzle, and the gas impacts the aerosol atomizing matrix, that is, atomizes the aerosol atomizing matrix, thereby forming atomized droplet particles and spraying them out of the nozzle. The atomizing nozzle here is just an example. The embodiment of the present invention adopts other atomizing nozzles of the prior art to achieve the effects described in the embodiment of the present invention. The droplets sprayed from the atomizing nozzle present a three-dimensional cone shape, the central area refers to the area near the central axis of the cone, and the two side areas refer to the areas outside the central area of ​​the cone. The mass distribution of droplets in the central area is concentrated, and it is more difficult to atomize. Usually, the mass distribution of the central area and the two side areas is 4:1.

[0033] like Figure 1As shown, an embodiment of the present invention provides an atomizer 10, which includes an atomizing nozzle 1 and a heater 2. The atomizing nozzle 1 is used to atomize an aerosol atomizing matrix and spray out an airflow containing the aerosol; the atomizing nozzle 1 is penetrated so that the airflow can flow inside and outside the atomizing nozzle 1; the atomizer 10 includes a housing 6, a liquid storage chamber 61 for storing the aerosol atomizing matrix is ​​provided in the housing 6, the atomizing nozzle 1 is located in the housing 6, and the atomizing nozzle 1 is connected to the liquid storage chamber 61 through a liquid inlet channel 62, the inlet of the atomizing nozzle 1 is connected to an air source to input an airflow, and the airflow enters the atomizing nozzle 1 from the air source, and is formed by Due to the change in the diameter of the atomizing nozzle 1 pipe, negative pressure is generated in the atomizing nozzle 1. The atomizing nozzle 1 is also connected to the liquid inlet channel 62, and the liquid inlet channel 62 is connected to the liquid storage chamber 61 for storing the aerosol atomizing matrix. The aerosol atomizing matrix can enter the atomizing nozzle 1 from the liquid inlet channel 62 under the action of the negative pressure of the atomizing nozzle 1. The airflow output from the air source has a certain pressure and impacts the aerosol atomizing matrix entering the atomizing nozzle 1, tearing it into small droplets, that is, atomizing the aerosol atomizing matrix.

[0034] like Figure 1 As shown, the atomizing nozzle 1 includes an air pump 13, an air intake section 11 and an atomizing chamber 12 which are connected in sequence. The air pump 13 refers to a device that discharges gas from a closed space or adds gas from a closed space. The air pump 13 continuously compresses the gas through electricity or manual force to generate air pressure, so that the airflow is pressed into the air intake section 11. The air intake section 11 is a variable cross-section structure with a coarse inlet and a thin outlet, and the atomizing chamber 12 is a uniform cross-section structure. The air intake section 11 is connected to the air pump 13. Due to the change in the cross-section of the air intake section 11, the airflow enters the air intake section 11 from the air pump 13 and enters the atomizing chamber 12 at a higher speed and with acceleration. There is a sudden increase in the cross-section from the outlet end of the air intake section 11 to the inlet end of the atomizing chamber 12, so that negative pressure is generated after the airflow enters the atomizing chamber 12 from the air intake section 11; the liquid inlet channel 62 is connected to the atomizing chamber 12 of the atomizing nozzle 1, and the aerosol The atomized matrix can enter the atomizing chamber 12 from the liquid inlet channel 62 under the action of the negative pressure of the atomizing chamber 12. The airflow output from the air source has a certain pressure and impacts the aerosol atomized matrix entering the atomizing chamber 12, tearing it into small droplets, that is, atomizing the aerosol atomized matrix. The aerosol produced by atomization is mixed with the airflow and sprayed outward in a cone shape. The sprayed aerosol and airflow can completely enter the heater 2. The airflow also includes large droplets produced by incomplete atomization, which can be further heated and atomized by the heater 2. The atomizing nozzle 1 here is just an example. The embodiment of the present invention adopts other atomizing nozzles of the prior art to achieve the effect described in the embodiment of the present invention. For example, the atomizing nozzle 1 can also be atomized by compressed air or the like. The liquid such as the aerosol atomized matrix obtains a large kinetic energy after being pressurized. After passing through the small hole and other structures, the liquid will be sprayed out at a very high speed, thereby generating atomization.

[0035] The atomizing nozzle 1 includes but is not limited to atomizing nozzles of mechanical atomizing modes such as direct injection, centrifugal, and rotary, and two-phase atomizing modes, including but not limited to atomizing nozzles of metal and non-metal materials. Mechanical atomization mainly relies on the high-speed jet generated by the liquid under the action of pressure difference to atomize itself, so it can be divided into direct injection nozzles, centrifugal nozzles, and rotary nozzles. Direct injection atomization and centrifugal atomization can be collectively referred to as pressure atomization. The direct injection nozzle mainly relies on the injection of water to achieve the purpose of atomization, and the water pressure requirement is relatively high. Moreover, the larger the diameter of the spray hole, the coarser the atomization, so the diameter of the spray hole cannot be too large, and the flow adjustment range is relatively small. The centrifugal nozzle uses the centrifugal force generated by the high-pressure water through the swirl device to generate a liquid film, which is broken and atomized by air. The effect of centrifugal atomization is better than that of direct injection atomization, but it also requires a higher water supply pressure, so the application conditions are limited. Rotary nozzles are generally divided into two categories: rotating body type and rotating nozzle type. The rotating body type is further divided into a rotating cup type and a rotating disk type. The cup atomization sprays water into the front end of the conical cup, and the water is spread into a thin film by the high-speed rotating cup, and the liquid is atomized by the combined effect of "centrifugal spray" and "speed spray". Similarly, the disc atomization relies on the high-speed rotating disc to atomize the liquid.

[0036] like Figure 1 As shown, the heater 2 is used to heat the airflow ejected from the atomizing nozzle 1, and the heater 2 is penetrated so that the airflow can flow inside and outside the heater 2. For example, the heater 2 is arranged downstream of the atomizing nozzle 1, and the airflow first passes through the atomizing nozzle 1 and then flows to the heater 2. The airflow containing the aerosol ejected from the atomizing nozzle 1 is further heated by the heater 2 and boils and evaporates, and the size of the droplet particles is further reduced. The process of generating aerosol by the atomizer of the embodiment of the present invention can be divided into a primary atomization stage and a secondary atomization stage. The primary atomization stage is realized by the atomizing nozzle 1. The airflow output from the air source has a certain pressure. The airflow is input into the atomizing nozzle 1 under the action of a certain pressure. At the same time, the aerosol atomization matrix is ​​pressed into the atomizing nozzle 1. At this time, the airflow can impact the aerosol atomization matrix, tearing it into small droplets, and outputting the aerosol after the primary atomization. The secondary atomization stage is realized by the heater 2. The aerosol generated in the primary atomization stage is heated by the heater 2 so that at least part of the droplets therein boil and evaporate into gas, further reducing the number and size of the droplets. The airflow or aerosol after two atomizations is finally released through the outlet of the atomizer 10 for the user to absorb.

[0037] like Figure 2a — Figure 3dAs shown, the heater 2 includes a plurality of mesh heating elements 3, each of which has a plurality of through holes 31 to form a mesh for airflow to pass through. The aerosol particle size generated by the nozzle atomization technology is usually 50μm-200μm. The mesh heating element 3 with a pore size range of 10μm-500μm is used. On the one hand, the porous feature can screen aerosol particles of different sizes, block large-sized aerosols, and pass small-sized aerosols; on the other hand, as shown in FIG. Figure 5 and Figure 6 As shown, Figure 5 The temperature field of the heating area of ​​the grid heating element 3 at 209° C. is shown. It can be seen that the temperature of the grid area used for atomizing the aerosol atomizing matrix is ​​relatively high and can reach 209° C.; Figure 6 The diagram illustrates the temperature rise rate of the grid heater 3 during heating and atomization. It can be seen that the grid heater 3 can be raised to a relatively high temperature in a short time. Therefore, it can be seen that the grid heater 3 can raise the temperature to between 200-300°C in a short time (1s), forming a temperature field in the space around the grid. This temperature field can heat and atomize the large-sized aerosol blocked by the grid, and further reduce the particle size of the small-sized aerosol. Thirdly, when the high-speed aerosol hits the solid part of the grid heater 3, the aerosol is broken and reduced in size. At the same time, the airflow is blocked and the flow rate is reduced, thereby achieving a smokeable effect.

[0038] Due to the use of grid heating element for secondary atomization, the requirements of the atomizing nozzle 1 can be lowered during the primary atomization, and it is not necessary to meet the requirements of the pumpable micro-particle droplets (1-10μm). Therefore, the volume and energy consumption of the air source output device such as the air pump of the atomizing nozzle can be appropriately reduced, thereby reducing the size of the product based on the atomizing nozzle atomization technology. Figure 2a — Figure 3d As shown, the heater 2 includes a plurality of grid heating elements 3, each of which has a plurality of through holes 31 to form a grid for airflow to pass through. The plurality of grid heating elements 3 can be arranged in a variety of ways. For example, the plurality of grid heating elements 3 can enclose a heating space, or can be arranged in layers. Compared with a single grid heating element 3, the temperature field of the heating space formed by the plurality of grid heating elements 3 is larger, thereby fully heating the droplets generated by atomization of the atomizing nozzle once, and the spatial atomization ability is strong.

[0039] The heater of the embodiment of the present invention includes multiple grid heating elements, each of which has multiple through holes to form a grid for airflow to pass through. The grid heating elements can be combined with different apertures to control the particle size of droplets generated by the atomizing nozzle during one atomization, and the size of the smoke particles during smoking can be controlled; and the multiple grid heating elements can form a larger heating space, so as to fully heat the droplets generated by the atomizing nozzle during one atomization, and the spatial atomization ability is strong, thereby solving the problem of narrow temperature field and insufficient heating in the single-layer grid heating space; in addition, users can freely set the number and placement of grid heating elements according to their own preferences, so as to control the particle size, taste and mouthfeel of the aerosol generated by atomization, thereby meeting the usage needs of different users.

[0040] In some embodiments, the material of the grid heater 3 is any material that can be heated by electricity, including but not limited to pure metals such as gold, silver, platinum, nickel, and iron, alloys such as iron-nickel, nickel-chromium, stainless steel, and iron-chromium-aluminum, and substrate materials covered with carbon-based films such as graphene and carbon nanotubes or metal nanofilms such as silver nanowires. For example, the grid heater 3 has a better heating effect and rate when iron-chromium-aluminum alloy is selected.

[0041] In some embodiments, the thickness of the grid heater 3 includes but is not limited to 10 μm-10 mm. For example, when the thickness of the grid heater 3 is 50 μm-1 mm, the strength of the grid heater 3 can also meet the use requirements while controlling the material cost of the grid heater 3.

[0042] In some embodiments, the grid heating element 3 is used for electronic atomization products, and the resistance value of the grid heating element 3 includes 0.1Ω-10Ω, and the effect is better when the resistance value range is set within 0.5Ω-2Ω.

[0043] In some embodiments, the mesh area shape of the mesh heating element 3 includes but is not limited to circle, square, rectangle, triangle, rhombus, pentagon / polygon, etc. The mesh surface of the mesh heating element 3 includes a plane mesh and a curved mesh.

[0044] In some embodiments, the shapes of the through holes of the grid heating element 3 include but are not limited to circle, square, rectangle, triangle, rhombus, pentagon / polygon, etc.

[0045] In some embodiments, the overall shape of the grid heating element 3 includes but is not limited to a flat shape, a concave shape, a convex shape, a cylindrical shape, a pen holder shape, a hemispherical shape, a spherical shape, etc., preferably a flat shape or a concave shape.

[0046] In some embodiments, with respect to the aperture and shape of the through holes of the grid heater 3 , the grid area of ​​the grid heater 3 includes but is not limited to a single-aperture grid, a multi-aperture grid, a single-shape grid, and a multi-shape grid.

[0047] In some embodiments, the heating temperature of the grid heating element 3 includes but is not limited to 100-300° C., and the temperature rise rate of the grid heating element 3 includes but is not limited to heating to 300° C. within 0.1s-1s.

[0048] In some embodiments, Figure 4a — Figure 4f As shown, the heater 2 includes a single mesh heating element 3, and the mesh heating element 3 has a plurality of through holes 31 to form a mesh for airflow to pass through. The single-layer scheme of the mesh heating element can be arranged with a single aperture or multiple apertures to produce different atomized particle size distribution ranges. Aerosols with different size particle ranges can produce different tastes, sweetness and smoking experiences. Figure 4a — Figure 4c The through holes 31 of different shapes formed in the grid heating element 3 are shown; Figure 4d — Figure 4f Grid areas of the grid heating element 3 with different shapes are illustrated.

[0049] In some embodiments, Figure 2a — Figure 3d As shown, the projection of at least one grid heating element 3 on a plane perpendicular to the first direction covers the projection of the outlet of the atomizing nozzle 1. The first direction is perpendicular to the cross section of the outlet. The cross section of the outlet refers to the cross section of the end / edge of the airflow flowing in the atomizing nozzle 1. The first direction is as shown in FIG. Figure 1 , Figure 2a and Figure 2b The first direction is perpendicular to 3a- Figure 4f The plane shown. It can be understood that at least one grid heating element 3 is placed horizontally or tilted and blocks the outlet of the atomizing nozzle 1. The projection of at least one grid heating element of the embodiment of the present invention on the plane perpendicular to the first direction covers the projection of the outlet of the atomizing nozzle, so that the airflow ejected through the outlet of the atomizing nozzle can be reheated and atomized by the grid heating element and then absorbed by the user. The aerosol atomized particles after reheating can be directly inhaled by the user, so that the user has a good inhalation experience.

[0050] In some embodiments, Figure 2a — Figure 2b As shown, multiple grid heating elements 3 are connected and enclosed to form a heating space 32, thereby forming a larger heating space temperature field. Multiple grid heating elements of the embodiment of the present invention are connected and enclosed to form a heating space, and the heating space temperature field can fully heat the spatial angle droplets atomized by the atomizing nozzle once, and the spatial atomization ability is strong.

[0051] In some embodiments, Figure 2a — Figure 2bAs shown, the heating space 32 is open at one end in the first direction. For example, at least three grid heating elements 3 are connected in sequence to enclose the heating space 32. Another grid heating element 3 covers one end of the heating space 32 in the first direction, and the other end is open, with the open end facing the outlet of the atomizing nozzle 1, so that the airflow ejected through the outlet of the atomizing nozzle 1 can enter the heating space 32 unimpeded for heating, and small-sized aerosol particles can pass through the grid heating element 3 for absorption by users; when large-sized aerosol particles are blocked by the grid and collide with the solid part of the grid heating element 3 at high speed, the aerosol is broken and reduced in size, and at the same time the airflow is blocked and the flow rate is reduced, thereby achieving an inhalable effect.

[0052] The heating space of the embodiment of the present invention is open at one end in the first direction, and the open end faces the outlet of the atomizing nozzle, so that the airflow ejected through the outlet of the atomizing nozzle can enter the heating space unimpeded for heating, and then achieve different inhalable experiences through the heating, screening, crushing, evaporation, atomization and other processes of the grid heating element.

[0053] In some embodiments, Figure 3a — Figure 3d As shown, Figure 3a , Figure 3b The through hole 31 in the shape of a strip is shown; Figure 3c , Figure 3d The polygonal through hole 31 is shown; the multiple grid heating elements 3 are arranged in layers in the first direction. The layered arrangement can be understood as that a straight line extending along the first direction passes through each of the multiple grid heating elements 3 in sequence during the extension process, which can be considered as a layered arrangement. The multiple grid heating elements 3 are preferably arranged in layers in parallel with each other. The areas where the grids of two adjacent grid heating elements 3 are arranged overlap at least partially in the first direction, so that the airflow ejected from the outlet of the atomizing nozzle can be heated in the area where the grids of one of the grid heating elements 3 are arranged, and then further heated and atomized in the area where the grids of another grid heating element 3 are arranged.

[0054] The multiple grid heating elements in the embodiment of the present invention are arranged in layers in the first direction, and the areas where the grids are set on two adjacent grid heating elements in the first direction at least partially overlap, so that the airflow ejected through the outlet of the atomizing nozzle can be heated after passing through the area where the grid is set on one of the grid heating elements, and then further heated and atomized after passing through the area where the grid is set on another grid heating element. Therefore, the user can freely set the number and placement of the grid heating elements according to his or her own preferences, so as to control the particle size, flavor and mouthfeel of the aerosol generated by atomization, thereby meeting the usage requirements of different users.

[0055] In some embodiments, Figure 3a — Figure 3d As shown, Figure 3b is Figure 3a A schematic diagram obtained by rotating a certain angle around the first direction based on Figure 3d is Figure 3c The schematic diagram is obtained by rotating a certain angle around the first direction based on the angle between the multiple grid heating elements 3; the angle between the multiple grid heating elements 3 includes 0-90 degrees. It can be understood that each grid heating element 3 can be rotated around the first direction to form a certain angle, and the angle includes 0-90 degrees; or the planes where each grid heating element 3 is located are inclined to each other and have a certain angle, and the angle includes 0-90 degrees, that is, the planes where the multiple grid heating elements 3 are located can be parallel or perpendicular to each other; the through holes 31 between each layer of grid heating elements 3 produce a combination of open, closed and semi-open and closed as the angle changes. When the atomizer is actually processed and set, the multiple grid heating elements 3 can be set to different angles. As the angle between the multiple grid heating elements 3 changes, the communication space of the through holes 31 of the multiple grid heating elements 3 changes accordingly; for example, when the angle between the multiple grid heating elements 3 is 0, the communication space of the through holes 31 of the multiple grid heating elements 3 is the largest; when the angle between the multiple grid heating elements 3 is 90 degrees, the communication space of the through holes 31 of the multiple grid heating elements 3 is the smallest. The distance between each layer of grid heating elements 3 includes but is not limited to 0.05 mm-5 mm. The grid heating elements 3 that are spaced far apart are not conducive to continuous heating of the airflow. Preferably, the distance is 0.1 mm-2 mm.

[0056] The angles between the multiple mesh heating elements in the embodiment of the present invention include 0-90 degrees. As the angles between the multiple mesh heating elements change, the connecting space of the through holes of the multiple mesh heating elements changes accordingly. Along the path of atomization, the through hole diameter of each layer varies with the angles between the multiple mesh heating elements, producing different combinations of open, closed and semi-open / closed, so that the taste and smoke volume can be adjusted more conveniently, bringing different smoking experiences.

[0057] In some embodiments, Figure 2a — Figure 4f As shown, the apertures and / or shapes of the through holes 31 in at least one grid heating element 3 are of various types, and / or the apertures and / or shapes of the through holes 31 in at least two grid heating elements 3 are different. The heater of the embodiment of the present invention controls the particle size of the droplets generated by the atomization nozzle through a combination of different apertures in a single grid heating element or a combination of different apertures in multiple grid heating elements, and controls the particle size of the smoke when the atomization nozzle is atomized.

[0058] In some embodiments, Figure 2a — Figure 4fAs shown, the diameter of the through hole 31 is greater than or equal to 0.01mm and less than or equal to 2mm. The smaller the diameter of the through hole 31, the finer the particles produced by atomization. To ensure a better smoking experience for users, it is preferably 0.1mm-0.5mm. The interval between adjacent through holes 31 of the same grid heating element 3 is greater than or equal to 0.01mm and less than or equal to 2mm. If the interval between adjacent through holes 31 of the same grid heating element 3 is too large, it is easy to waste materials. If it is too small, the through holes 31 of the grid heating element 3 will be too densely distributed, which is not conducive to the heating of the grid heating element 3. It is preferably 0.1mm-0.5mm. The interval between adjacent through holes of the same grid heating element in the embodiment of the present invention is at least greater than the diameter of the through hole, so that multiple grid heating elements can be set at different angles, changing the connecting space of the through holes of multiple grid heating elements, and producing different combinations of opening, closing and semi-opening and closing, so that the particle size of the droplets produced by the atomizing nozzle at one time is controlled, and the size of the smoke particles during smoking is controlled.

[0059] In some embodiments, Figure 1 As shown, the heater 2 is located downstream of the outlet of the atomizing nozzle 1, and the minimum spacing between the grid heating element 3 and the atomizing nozzle 1 in the first direction is 0.5-20mm. If the spacing between the grid heating element 3 and the atomizing nozzle 1 in the first direction is too large, it may cause some atomized particles to condense and reflux before secondary heating and atomization. If the spacing between the grid heating element 3 and the atomizing nozzle 1 in the first direction is too small, the speed at which the airflow ejected from the atomizing nozzle 1 hits the grid heating element 3 is too large, which is easy to affect the service life of the grid heating element 3. Preferably, it is 1mm-5mm. The grid heating element 3 can be in the upward, downward, left, right, and other directions relative to the atomizing nozzle 1, and the grid heating element 3 can be kept at the outlet of the atomizing nozzle 1, preferably perpendicular to the outlet cross section of the atomizing nozzle 1. The heater in the embodiment of the present invention is located downstream of the outlet of the atomizing nozzle, so that the airflow first passes through the atomizing nozzle and then flows to the heater. The airflow containing aerosol sprayed from the atomizing nozzle is further heated by the heater to boil and evaporate, and the size of the droplet particles is further reduced. The aerosol atomized particles after secondary heating can be directly inhaled by the user, so that the user has a good inhalation experience.

[0060] like Figure 1 As shown, the grid bracket 5 is a structure for supporting the grid heating element 3, including but not limited to a columnar support rod, a grid hole support sheet, and a cylindrical support surface. The grid bracket 5 can generate heat together with the supported grid heating element 3, or it can generate heat alone, or it can not generate heat. The material of the grid bracket 3 includes heat-resistant materials such as metal, alloy, ceramic, and high-temperature resin. For example, in the case of multiple grid heating elements 3, each grid heating element 3 is supported by a different grid bracket 5 and suspended in the air.

[0061] like Figure 7As shown, the embodiment of the present invention further provides an atomizing device 4, which includes an atomizer 10 and a power supply 41. The power supply 41 is used to provide electrical energy to the atomizer 10. For example, the power supply 41 can be electrically connected to the heater 2, so that the heater 2 can generate heat to heat the airflow into atomization. Figure 1 As shown, the atomizing device 20 has an air pump 13, and the air pump 13 is connected to the air inlet section 11 to input gas that impacts the aerosol atomizing matrix, so that the airflow entering the air inlet section 11 can be accelerated to enter the atomizing chamber 12; the air pump 13 refers to a device that discharges gas from a closed space or adds gas from a closed space, and the air pump 13 continuously compresses the gas through electricity or manual force to generate air pressure, so that the airflow is pressurized into the atomizing nozzle 1. The power supply 41 is also used to provide electrical energy to the air pump 13, the liquid storage chamber 61 contains the aerosol atomizing matrix, the atomizing nozzle 1 is connected to the liquid storage chamber 61 to inhale the aerosol atomizing matrix, and the air inlet section 11 is connected to the air pump 13 to input the airflow, and the airflow impacts the aerosol atomizing matrix under the pressure of the air pump 13 to atomize it into an aerosol. In addition, the atomizing nozzle 1 can also achieve atomization by compressed air or the like. Liquids such as aerosol atomizing matrix obtain greater kinetic energy after being pressurized. After passing through structures such as small holes, the liquid will be ejected at a high speed, thereby generating atomization.

[0062] The atomizing device of an embodiment of the present invention includes an atomizer and a power supply. The atomizing nozzle is connected to the air source, and the airflow can be input into the airflow channel at a certain pressure. The atomizing nozzle is also connected to the liquid storage chamber to inhale the aerosol atomizing matrix, and the airflow in the atomizing nozzle impacts the aerosol atomizing matrix under a certain pressure to atomize it into an aerosol.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
