DETAILED DESCRIPTION

[0029] The core of the present invention is to provide an aerosol generating device, which can effectively simplify the structure, facilitate the layout, and improve the aerosol generation efficiency.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Please refer to Figures 1 to 5 , Figure 1 A front view of a separation structure of a specific embodiment of the aerosol generating device provided by the present invention; Figure 2 A side view of a separation structure of a specific embodiment of the aerosol generating device provided by the present invention; Figure 3 for Figure 1 A schematic diagram of the combined structure of the aerosol generating device shown; Figure 4 for Figure 2 A schematic diagram of the combined structure of the aerosol generating device shown; Figure 5 This is a schematic diagram of the distribution of magnetic lines of force in the aerosol generating device provided by the present invention.

[0032] In this embodiment, the aerosol generating device comprises:

[0033] A first housing assembly 1, the first housing assembly 1 comprises a first housing body 11 and a heating element 12, an air flow channel 112 is arranged in the first housing body 11, and the heating element 12 is installed in the air flow channel 112;

[0034] The second shell component 2 includes a second shell body 21 and a coil 23. The second shell body 21 is provided with a housing portion 26. The coil 23 is located on at least one side of the housing portion 26 away from the airflow channel 112. The heating element 12 is installed in the housing portion 26. The magnetic lines of force generated by the coil 23 pass through the heating element 12.

[0035] It should be noted here that the heating element 12 is installed in the accommodating portion 26 by installing the airflow channel 112 in the accommodating portion 26. The heating element 12 is located at the first end of the airflow channel 112. When the first end of the airflow channel 112 is installed in the accommodating portion 26, the heating element 12 is just located in the accommodating portion 26, close to the position of the coil 23.

[0036] Furthermore, the heating element 12 should be located at a position where the density of magnetic lines of force generated by the coil 23 is the largest. Preferably, in the axial projection direction of the coil 23 , the heating element 12 is located in the middle of the coil 23 , so as to ensure that as many magnetic lines of force as possible pass through the heating element 12 .

[0037] Furthermore, an electrical component 22 is further disposed in the second shell body 21 , and the electrical component 22 is used to supply power to the coil 23 .

[0038] Specifically, an oil tank 111 is further provided in the first shell body 11, and the oil tank 111 is connected to the air flow channel 112. An oil guide channel is provided between the oil tank 111 and the heating element 12, and the first end of the air flow channel 112 refers to the end of the air flow channel 112 close to the second shell body 21; the coil 23 is arranged in the second shell component 2 of the aerosol generating device, and the heating element 12 is arranged in the first shell component 1 of the aerosol generating device. When the aerosol generating device is used by the user, the first shell component 1 and the second shell component 2 of the aerosol generating device are combined together. At this time, the axis of the heating element 12 coincides with the axis of the coil 23. At the same time, a high-frequency magnetic field will be generated near the coil 23, and part of the magnetic lines of force will start from the inside of the coil 23, pass through the edge of the heating element 12, and Passing through the interior of the heating element 12, and then reaching the edge of the heating element 12 again, when there are two coils 23, the magnetic lines of force enter the interior of another coil 23 again, and then return from the outside of the coil 23 to the interior of another coil 23, and this part of the magnetic lines of force passing through the heating element 12 will cause the heating element 12 to heat up, thereby achieving the purpose of heating the aerosol matrix; by setting two coils 23, the density of the magnetic lines of force is higher, and the heating efficiency of the heating element 12 is high; of course, the number of heating elements 12 can also be multiple to further improve the heating efficiency; the airflow channel 112 is located in the middle of the oil tank 111, and the aerosol matrix in the oil tank 111 flows to the vicinity of the heating element 12 to form an aerosol, which flows from the first end to the second end along the airflow channel 112 for the user to inhale. Further, the heating element 12 is made of a material with high relative magnetic permeability, low resistivity, and high saturation magnetic induction intensity.

[0039] The aerosol generating device provided by the present invention arranges the heating element 12 in the air flow channel 112 and arranges the coil 23 on at least one side of the accommodating portion 26 away from the air flow channel 112, thereby avoiding the arrangement of the coil 23 around the heating element 12, so that the space where the coil 23 is located and the space required by the air flow channel 112 are independent of each other and are no longer restricted by space. The diameter of the coil 23 can be reduced to save space. At the same time, the coil 23 can be wound with more turns to generate a stronger magnetic field, further improving the heating efficiency of the heating element 12.

[0040] In some embodiments, the first housing body 11 is detachably connected to the second housing body 21. In the above arrangement, the heating element 12 and the coil 23 are respectively arranged in the first housing assembly 1 and the second housing assembly 2, and the space where the coil 23 is located is independent of the space required for the oil guide channel and the air flow channel 112 in the first housing assembly 1, which is convenient for arrangement and saves space.

[0041] In some embodiments, a gap is provided between the heating element 12 and the inner wall of the airflow channel 112 for aerosol flow. Specifically, after the aerosol is formed, it will enter the airflow channel 112, and the heating element 12 is installed in the airflow channel 112. In order to reduce the obstruction of the heating element 12 to the aerosol, a gap is provided between the heating element 12 and the inner wall of the airflow channel 112 to ensure that the aerosol flows out smoothly. Further, the heating element 12 is in the shape of a sheet, a cylinder, a column or a strip, preferably a cylinder. The cylindrical heating element 12 is easy to install, and the heating element 12 is hollow inside, which facilitates the flow of aerosol; of course, the shape of the heating element 12 can be selected as needed, and is not limited to the shape given in this embodiment. It should be noted that the heating element 12 should be arranged as much as possible in the axial direction of the coil 23, so as to ensure that more magnetic lines of force pass through the heating element 12 and improve the heating efficiency of the heating element 12.

[0042] In some embodiments, the axial direction of the coil 23 is perpendicular to the installation direction of the heating element 12 and the receiving portion 26. Specifically, by arranging the axial direction of the coil 23 to be perpendicular to the installation direction of the airflow channel 112 and the receiving portion 26, that is, perpendicular to the axial direction of the entire device, the purpose is to save space and not be restricted by the space of other components, and improve energy utilization efficiency. Specifically, the coil 23 can be placed separately on both sides of one end of the second shell body 21 close to the first shell body 11, thereby avoiding the solution in the prior art that the heating element 12 will be wrapped in the center of the coil 23, thereby avoiding the need to leave some space between the heating element 12 and the coil 23, such as the oil guide channel, the airflow channel 112, the oil guide cotton or ceramic, the outer wall of the oil tank 111, the outer wall of the battery rod, etc., resulting in a relatively large diameter of the overall device. By adopting the vertical placement solution, the space of the coil 23 and the heating element 12 is separated from each other, the space constraints between each are reduced, and the diameter of the coil 23 can be relatively small, so that more turns can be wound, which is conducive to concentrating the magnetic field. It should be noted here that the axial direction of the coil 23 is perpendicular to the installation direction of the air flow channel 112 and the accommodating portion 26, so as to make the magnetic lines of force generated by the coil 23 pass through the heating element 12 as much as possible, thereby improving the heating efficiency of the heating element 12; of course, the installation direction of the coil 23 and the installation direction of the heating element 12 can also be inclined relative to the installation direction of the air flow channel 112 and the accommodating portion 26, as long as the axial directions of each coil 23 and the heating element 12 are consistent. Of course, without considering the efficiency, the installation direction of each coil 23 and the heating element 12 can also be adjusted as needed.

[0043] In some embodiments, the coil 23 includes a first coil 231 and a second coil 232, and the axes of the first coil 231 and the second coil 232 coincide with each other. Furthermore, the axes of the first coil 231 and the second coil 232 are perpendicular to the installation direction of the heating element 12 and the accommodating portion 26, thereby ensuring that the arrangement space of the first coil 231 and the second coil 232 is more flexible, and reducing the influence of the position of the oil guide channel and the air flow channel 112.

[0044] Specifically, the winding directions of the first coil 231 and the second coil 232 are the same or opposite, and the circuit connection relationship between the first coil 231 and the second coil 232 can be in series or in parallel; the two coils 23 can be connected in the same control circuit or in two control circuits respectively. Specifically, the direction of the magnetic field generated by the coil 23 is not only related to the winding direction of the coil 23, but also related to the direction of the current passing through the coil 23. Therefore, when the first coil 231 and the second coil 232 are energized, the direction of the current in the coil 23 needs to be considered. When the windings of the first coil 231 and the second coil 232 are opposite, the direction of the current passing through them should also be opposite. When the windings of the first coil 231 and the second coil 232 are the same, the direction of the current passing through them should also be the same, so as to avoid the magnetic field generated by the two coils 23 from canceling out. At the same time, since the excitation current applied to the first coil 231 and the second coil 232 is a high-frequency oscillation, the polarities generated by the first coil 231 and the second coil 232 are different at any time. Therefore, it is necessary to control the direction of the current input into the first coil 231 and the second coil 232 by the control circuit board 222 so that the polarity and phase of each coil 23 are the same at any time. The magnetic flux will not be offset but will be strengthened.

[0045] When the polarity of the first coil 231 and the second coil 232 is the same, since the heating element 12 is also made of a material with a certain magnetic permeability, the magnetic lines of force near it will be guided to the inside of the heating element 12, and the distribution of the magnetic lines of force in space is continuous. When the magnetic lines of force generated by the center of the first coil 231 reach the vicinity of the heating element 12, they will be guided to the inside of the heating element 12, and then pass through the heating element 12 to enter the center of the second coil 232. Figure 5 The heating wire acts as a bridge between the magnetic lines of force between the first coil 231 and the second coil 232 , thereby enhancing the transmission effect of the magnetic lines of force in the two coils 23 and achieving efficient heating of the heating element 12 .

[0046] In some embodiments, a magnetic conductor 24 is further included, and the magnetic conductor 24 is installed inside the coil 23. Specifically, by arranging the magnetic conductor 24 at the center of the coil 23, the magnetic field can be further strengthened, thereby further improving the heating efficiency of the heating element 12.

[0047] In some embodiments, a cavity is provided in the heating element 12 , and the magnetizer 24 is installed in the heating element 12 ; similarly, providing the magnetizer 24 in the heating element 12 can also strengthen the magnetic field and further improve the heating efficiency of the heating element 12 .

[0048] In some embodiments, the heating element 12 is located on the axis of the coil 23. Preferably, the extension direction of the heating element 12 is parallel to the axis of the coil 23, that is, the axis of the coil 23 passes through the heating element 12 to the greatest extent possible, thereby ensuring that magnetic lines of force with greater density pass through the heating element 12 and achieving the highest heating efficiency.

[0049] In some embodiments, the electrical component 22 includes a power supply component 221 and a circuit board 222, the power supply component 221 is connected to the circuit board 222, and the circuit board 222 is connected to the coil 23. Specifically, the coil 23 is connected to the circuit board 222, and the circuit board 222 includes a control circuit for the coil 23; the power supply component 221 can be a battery, and the electric energy of the power supply component 221 is transmitted to the coil 23 through the circuit board 222, and then transmitted to the heating element 12 by the coil 23, and the heating element 12 finally transmits the energy to the aerosol matrix to generate an aerosol.

[0050] In some embodiments, an oil guide component is further included, which is installed in the first housing body 11 and located between the oil tank 111 and the heating element 12. Specifically, the oil guide component is a porous oil guide medium. When the aerosol generating device is used, the aerosol matrix flows from the oil tank 111 to the position of the oil guide component. The outlet of the oil tank 111 is provided with an oil guide channel. The oil guide component is located in the oil guide channel. Then the oil guide component conducts the aerosol matrix to the position of the heating element 12 to achieve the purpose of heating the aerosol matrix.

[0051] In some embodiments, at least two arrangement bins 25 are provided on a protrusion at one end of the second shell body 21 close to the first shell body 11, and a recess is formed between two adjacent arrangement bins 25 to form a receiving portion 26, and a coil 23 is provided in at least one arrangement bin 25. The provision of the arrangement bin 25 is, on the one hand, conducive to forming the receiving portion 26, facilitating the assembly of the first shell body 11 and the second shell body 21, and on the other hand, by installing the coil 23 in the arrangement bin 25, the original position of the electrical component 22 is not affected, and there is no need to increase the volume of the second shell body 21, while meeting the heating requirements of the coil 23 on the heating element 12, which is conducive to miniaturization.

[0052] Furthermore, there are two arrangement bins 25, which are arranged on both sides of the second shell body 21 and are symmetrically distributed, so that the magnetic field strength at both ends of the heating element 12 is consistent, and at the same time, the accommodating portion 26 can be ensured to be located in the middle of the second shell body 21, ensuring that the first shell body 11 and the second shell body 21 are more stable after assembly. Of course, the number and position of the arrangement bins 25 can also be selected as needed, and are not limited to the method given in this embodiment.

[0053] In some embodiments, the number of coils 23 and arrangement bins 25 is the same and corresponds one to one, and the axes of the coils 23 coincide. Specifically, by providing multiple coils 23, the strength of the magnetic flux lines can be increased, thereby improving the heating efficiency of the heating element 12.

[0054] In some embodiments, each coil 23 is independent of each other and connected in parallel to the electrical component 22. Specifically, each coil 23 is preferably connected to the electrical component 22 separately, so that when a single coil 23 is powered off, other coils 23 can continue to generate a magnetic field to ensure the normal operation of the heating element 12; it should be noted that the winding directions of each coil 23 can be the same or different, and the direction of the current passed through the coil 23 should be matched with the winding direction, so that the magnetic fields generated by each coil 23 are superimposed on each other to avoid demagnetization.

[0055] In a specific embodiment, the aerosol generating device includes a first shell body 11 and a second shell body 21, the first shell body 11 is provided with an oil tank 111 and an air flow channel 112, the air flow channel 112 is installed with a heating element 12, and the second shell body 21 is arranged with a coil 23, a circuit board 222, a power supply component 221 and other related structures; the device is divided into two separable upper and lower parts, the upper part is the first shell body 11, and the lower part is the second shell body 21; the coil 23 includes a first coil 231 and a second coil 232, the first coil 231 and the second coil 232 are arranged on both sides of the upper end of the second shell body 21, and the axes of the first coil 231 and the second coil 232 are placed to overlap each other, so as to generate a symmetrical magnetic field, such as Figure 1 and Figure 2 When the first shell body 11 and the second shell body 21 are connected together, the axis of the heating element 12 in the first shell body 11 will coincide with the axis of the first coil 231 and the second coil 232, as shown in FIG. Figure 3 and Figure 4 shown.

[0056] Specifically, when the aerosol generating device is working, a high-frequency magnetic field is generated near the coil 23. Since the heating element 12 is made of a material with a certain relative magnetic permeability and resistivity and the coil 23 is placed close to the heating element 12, Figure 5As shown, the magnetic lines of force generated by the coil 23 will sequentially pass through the interior of the first coil 231, the heating element 12, and the interior of the second coil 232, and finally return to the first coil 231 from the space outside the second coil 232. The magnetic lines of force passing through the heating element 12 will generate hysteresis loss, eddy current loss, and residual loss inside the heating element 12, thereby causing the heating element 12 to heat up, thereby providing the energy required to generate aerosol.

[0057] Compared with the traditional electromagnetic induction aerosol generating device, the aerosol generating device has the following advantages:

[0058] 1. The diameter of the coil 23 is smaller, saving space and materials;

[0059] 2. The magnetic lines of force passing through the coil 23 can pass through the heating element 12 more to cause heating, which is more efficient;

[0060] 3. The coil 23 can be wound with more turns to generate a stronger magnetic field;

[0061] 4. The space where the coil 23 is located is independent of the space required by the oil guide channel, the air flow channel 112, and the oil guide component, and is no longer restricted by space, so the structural design of the aerosol generating device is more flexible;

[0062] 5. A magnetic conductor 24 is added at the center of the coil 23 to further strengthen the magnetic field.

[0063] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
