Figures 1-2 show an electronic atomization device in a first embodiment of the present invention. The electronic atomization device can be used to atomize a liquid substrate to generate an aerosol for the user to inhale. In this embodiment, it can be roughly cylindrical. shape. It is understandable that in other embodiments, the electronic atomization device can also be in other shapes such as elliptical column, flat column, square column, etc.

The electronic atomization device may include a housing, an airflow sensing element 2, a control module 3, a power supply 4, a liquid storage component 5 and a heating component 6 contained in the housing. The airflow sensing element 2 is electrically connected to the control module 3, and is used to sense changes in the airflow when the user puffs or stops smoking, and feeds back corresponding signals to the control module 3; the control module 3 is electrically connected to the heating component 6, and is used to sense the airflow according to the airflow sensor. The corresponding feedback signal of element 2 controls the operation of heating component 6 and can also control the heating power of heating component 6. The power supply 4 is electrically connected to the air flow sensing element 2, the control module 3, and the heating assembly 6 respectively, and is used to provide electric energy to the air flow sensing element 2, the control module 3, and the heating assembly 6. The liquid storage assembly 5 includes a liquid storage chamber 52 for storing a liquid substrate. The heating component 6 includes a capillary channel 614 that is liquid-conductingly connected to the liquid storage chamber 52 and has capillary force, and a heater that matches the capillary channel 614; it can be understood that the heating component 6 moves the liquid storage chamber 52 based on the principle of capillary phenomena. Part of the liquid matrix in the capillary channel 614 is directed into the capillary channel 614; the heater is used to heat and atomize the liquid matrix absorbed by the capillary channel 614; the heated liquid matrix changes into an aerosol, and the aerosol is brought out by the air flow for the user to inhale. . Further, the outer shell includes a lower shell and an upper shell that is longitudinally coupled to the upper end of the lower shell. In some embodiments, the lower shell may be in the shape of a cylinder with openings at both ends, and the shell further includes a base longitudinally covering the opening at the lower end of the lower shell. It is understood that in other embodiments, the base can also be integrally formed with the lower shell.

In some embodiments, a bracket assembly may be provided in the lower shell, and the bracket assembly divides the lower shell into a first receiving space located at the upper part and a second receiving space located at the lower part. Both the control module 3 and the power supply 4 can be accommodated in the second accommodation space. The control module 3 may include a circuit board and a control circuit formed on the circuit board, and the power supply 4 may include a battery. The liquid storage component 5 can be received in the first receiving space and supported on the bracket component. The airflow sensing element 2 can be installed at the bottom of the bracket assembly. In some embodiments, the airflow sensing element 2 may be a negative pressure sensor.

In some embodiments, the housing may further include a suction nozzle 11 disposed on the top of the upper housing, through which the user can inhale the aerosol. The suction nozzle 11 is in the shape of a hollow tube, and its inner wall defines an inhalation channel for outputting aerosol. The upper end of the suction nozzle 11 can be sucked by the user, and the lower end of the suction nozzle 11 can be connected to the capillary channel 614 . In some embodiments, the suction nozzle 11 and the upper shell are formed separately and then assembled together; in other embodiments, the suction nozzle 11 and the upper shell can also be integrally formed.

In some embodiments, the electronic atomization device may further include a dust cover detachably provided outside the upper shell. When the electronic atomizer is not needed, a dust cover can be placed outside the upper shell to prevent dust and other impurities from entering the suction channel.

As shown in FIG. 1 , the liquid storage assembly 5 includes a liquid storage shell 51 with a cavity inside, and the cavity is the above-mentioned liquid storage chamber 52 . Optionally, the shape of the longitudinal section of the liquid storage shell 51 may be a rectangle, a parallelogram, an angle, a circle or an ellipse; of course, it may also be in other shapes, which are not specifically limited here.

As shown in FIGS. 1 and 2 , the heating component 6 includes a capillary tube 61 with capillary force that is fluid-conductingly connected to the liquid storage chamber 52 , and an electromagnetic coil 62 that cooperates with the capillary tube 61 . Alternatively, the capillary tube 61 may be a magnetically permeable tube made of a material with high magnetic permeability, such as a magnetically permeable metal tube made of a metal material with a relatively high magnetic permeability. It can be understood that whether the magnetic permeability meets the definition of "high" can be determined based on whether it can cooperate with the electromagnetic coil 62, and it can meet the needs of solving technical problems.

In some embodiments, the capillary tube 61 is made of magnetically permeable metal material and has a hollow tubular structure, and its inner wall defines the capillary channel 614 mentioned above. By adjusting the inner diameter of the capillary tube 61, the capillary tube 61 can produce capillary adsorption, thereby flowing the liquid matrix in the liquid storage chamber 52 to the capillary tube 61, thereby achieving the effect of automatically supplying the liquid matrix; at the same time, no matter the liquid storage shell 51 is in different positions , under capillary action, it can ensure that the liquid level of the liquid matrix in the capillary tube 61 remains consistent. The electromagnetic coil 62 is used to heat the capillary tube 61 , and the control module 3 can control the amount of heat generated by the capillary tube 61 .

It can be understood that in the present invention, by inserting a capillary tube 61 with a relatively small inner diameter into the liquid storage chamber 52, according to the principle of capillary phenomenon, part of the liquid matrix in the liquid storage chamber 52 flows into the capillary tube 61 and rises along the direction of the capillary channel 614. to a height higher than the liquid level in the liquid storage chamber 52 . In the present invention, the liquid substrate is realized to rise along the capillary tube 61 through the capillary phenomenon formed by the capillary tube 61 .

After the liquid substrate rises to the preset position of the capillary tube 61, an electromagnetic electric heater is set at a corresponding position on the outer periphery of the capillary tube 61 to form induction heating of the capillary tube 61.

Due to the capillary action of the capillary tube 61, the liquid level of the liquid matrix located inside the capillary tube 61 will be relatively higher than the liquid level of the liquid storage chamber 52, so that the contact area between the liquid matrix located inside the capillary tube 61 and the wall of the capillary tube 61 is large, and the capillary tube 61 is heated to The liquid matrix inside can be heated and evaporated at a relatively low temperature, so that the capillary 61 can complete the evaporation of the liquid matrix during the instantaneous heating of the electromagnetic coil 62 and improve the evaporation efficiency. After the liquid matrix in the capillary tube 61 located at the position corresponding to the electromagnetic coil 62 evaporates, a vacancy will be formed in the liquid matrix in the capillary tube 61. Due to the capillary phenomenon, the liquid matrix located in the liquid storage chamber 52 will be automatically replenished into the capillary tube 61, thereby Achieve automation, no need for supplementary parts, save energy consumption and reduce manufacturing costs.

In addition, due to the low temperature of the heating atomization process of the present invention, the pre-prepared flavor and fragrance system of the liquid matrix can be completely protected, and ultimately the user can feel the unique taste corresponding to the original e-liquid when smoking.

Further, in some embodiments, the capillary tube 61 extends upward along the axial direction of the liquid storage shell 51 . Preferably, the axial direction of the capillary tube 61 is perpendicular to the liquid level of the liquid matrix in the liquid storage chamber 52 . In some embodiments, the capillary tube 61 may include an intraluminal section 611 located within the liquid storage chamber 52 and an extraluminal section 612 extending outside the liquid storage chamber 52 . Specifically, one end of the inner section 611 is located below the liquid level in the liquid storage chamber 52 , and there is a distance between one end of the inner section 611 and the bottom of the liquid storage shell 51 , and the other end of the inner section 611 is between the outside and the outside of the cavity. Segment 612 is fixedly connected such that the liquid matrix flows toward the extraluminal segment 612 . One end of the outer section 612 close to the suction nozzle 11 is connected to the suction nozzle 11 to communicate with the inhalation channel, and then the aerosol can be output. In this embodiment, the inner diameters of the intraluminal section 611 and the extraluminal section 612 are the same. In other embodiments, the inner diameter of the intraluminal section 611 is larger than the inner diameter of the extraluminal section 612, or the inner diameter of the capillary tube 61 can be reduced from bottom to top. As the inner diameter of the capillary tube 61 decreases, its capillary force will increase, allowing the liquid substrate to obtain greater capillary force.

In some embodiments, the outer section 612 includes a first outer section unit 6121 and a second outer section unit 6122 connected below the first outer section. Among them, the first outer section unit 6121 is used to generate heat; specifically, the electromagnetic coil 62 is provided on the outer periphery of the first outer section unit 6121 to act on the first outer section unit 6121 to cause it to generate heat. The second outer section unit 6122 is used as a communication tube between the first outer section unit 6121 and the intraluminal section 611 to transport the liquid matrix in the intraluminal section 611 to the first outer section unit 6121.

Furthermore, the cross-sectional shape of the capillary tube 61 may be circular, elliptical, angular or square; of course, it may also be in other shapes, which are not specifically limited here.

In some embodiments, the capillary tube 61 may be made of a metal material with high magnetic induction intensity. Optionally, it includes iron, stainless steel or nickel-iron. In some embodiments, since the electromagnetic coil only acts on the first outer section unit 6121, in the capillary tube 61, only the first outer section unit 6121 can be made of magnetically conductive metal material, while the inner section 611, The second outer section unit 6122 can be made of other materials.

In some embodiments, the number of capillary tubes 61 can be one or more than two; in this embodiment, the number of capillary tubes 61 is one.

In some embodiments, the diameter of capillary channel 614 is adapted to the viscosity of the liquid matrix. In some embodiments, the diameter of the capillary channel 614 is selected from 0.1 to 5 mm as its diameter size according to liquid substrates of different viscosities. In this embodiment, the outer diameter of the capillary tube 61 can also be adapted according to the actual application. When the structural strength needs to be ensured, the outer diameter of the capillary tube 61 is increased. When the structural space needs to be saved, the outer diameter of the capillary tube 61 is reduced.

In some embodiments, a first preset distance is left from the end of the cavity section 611 below the liquid level to the bottom of the liquid storage case 51 , and the first preset distance is adapted to the height of the liquid storage case 51 . In some embodiments, the first preset distance is 1/5~1/20 of the height of the liquid storage shell 51 . It can be understood that if the end of the intraluminal section 611 located below the liquid level is too close to the bottom of the liquid storage shell 51, it will easily affect the liquid matrix entering the capillary 61; if the end of the intraluminal section 611 located below the liquid level is too close to the bottom of the liquid storage shell 51, When it is far away from the bottom of the liquid storage shell 51, it is not conducive to long-term liquid supply; because when the liquid level of the liquid matrix drops below the capillary tube 61, the liquid supply cannot be provided.

Further, the housing may also include a transition tube 12 connected between the suction nozzle 11 and the capillary tube 61; the transition tube 12 has a hollow structure and is used to communicate the suction channel and the capillary channel 614. Optionally, the material of the transition tube 12 may include PTC ceramic material, plastic or metal. In some embodiments, the airflow sensing element 2 has a sensing element for sensing airflow changes. The sensing element can be disposed in the transition pipe 12. When a negative pressure is formed in the transition pipe 12, the pressure is transmitted to the airflow sensing element 2, so that The airflow sensing element 2 transmits signals to the control module 3 .

Furthermore, the electromagnetic coil 62 is in a three-dimensional spiral shape and can be arranged around the capillary tube 61 to act on the capillary tube 61 . In this embodiment, the electromagnetic coil 62 is wound around the outer periphery of the first outer section unit 6121; and the electromagnetic coil 62 has two electrode terminals for electrical connection with the power source 4, and can produce an effect on the first outer section after being energized. The alternating magnetic field of the unit 6121 causes the first outer unit 6121 to generate heat. The inner diameter of the electromagnetic coil 62 is adapted to the outer diameter of the capillary tube 61 .

In some embodiments, the axial length of the electromagnetic coil 62 is adapted to the length of the first outer segment unit 6121. In this embodiment, the axial length of the electromagnetic coil 62 is 3~30 mm, and the length of the first outer unit 6121 is 10% longer than the axial length of the electromagnetic coil 62 .

In some embodiments, a second preset distance is left between the outer wall of the electromagnetic coil 62 and the outer wall of the capillary tube 61; it can be understood that when the distance is too close, the capillary tube 61 is easily melted; when the distance is too far, the capillary tube 61 The heating effect is poor or even useless. Preferably, the range interval of the second preset distance is [2, 10], and the unit is mm.

In some embodiments, the capillary tube 61, the suction nozzle 11, the liquid storage shell 51 and the outer shell are coaxially arranged.

Furthermore, the heating component 6 may also include a thermal insulation layer 63 disposed between the electromagnetic coil 62 and the capillary tube 61; the thermal insulation layer 63 is used to maintain heat and reduce the heat loss generated by the capillary tube 61. In some embodiments, the thermal insulation layer 63 is attached to the outer wall of the capillary tube 61 . In some embodiments, the thermal conductivity of the thermal insulation layer 63 is less than 1 W/(m·K), and may include thermal insulation cotton or thermal insulation pads.

In some embodiments, the main work steps of the entire heating assembly 6 include:

Add liquid matrix into the liquid storage shell 51;

Insert the capillary tube 61 into the liquid storage shell 51 and leave a first preset distance from the bottom of the liquid storage shell 51; the capillary tube 61 absorbs the liquid substrate to the corresponding electromagnetic coil position through capillary action;

When inhaling toward the suction nozzle 11, a negative pressure is formed in the transition tube 12, and the pressure is transmitted to the airflow sensing element 2, and the airflow sensing element 2 transmits the signal to the control module 3;

The control module 3 controls the voltage or power delivered by the power supply 4 to the electromagnetic coil 62 according to the level signal transmitted by the airflow sensing element 2 .

When the electromagnetic coil 62 works, the capillary tube 61 at the corresponding position will generate Joule heat and the temperature will rise, heating and evaporating the liquid matrix that has been adsorbed in it, forming bubbles 613; these bubbles 613 are along the wall of the capillary tube 61 It continues to rise to form an aerosol, which is transported to the oral cavity through the suction nozzle 11 .

In addition, the electromagnetic coil 62 and the capillary tube 61 are insulated from high temperatures by a heat insulating layer 63 outside the capillary tube 61 .

In summary, the present invention effectively reduces the heating temperature of the atomized liquid substrate and improves the evaporation efficiency by arranging the capillary tube 61 and the electromagnetic coil 62 based on the capillary phenomenon and the principle of electromagnetic induction heating; it can also solve the problem of high-temperature heating of porous media mist in related technologies. The technical problem is that the smoking method will lead to poor smoking taste and a burnt smell. At the same time, the present invention uses the capillary tube 61 with capillary force to transport the liquid matrix. On the one hand, it can avoid the leakage problem caused by ceramic ventilation and other methods in related technologies. On the other hand, the liquid matrix can be automatically replenished into the capillary tube 61. , thereby realizing automatic supply without the need for supplementary supplements from other parts, saving energy consumption and reducing manufacturing costs.
