This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Referring to fig. 1 and 5, the heater 10 of the present invention comprises a heating body 20, wherein the heating body 20 can be used to heat a solid block-shaped or strip-shaped aerosol substrate, specifically an aerosol-generating substrate, which can atomize a part of the added components, such as fragrance components, during heating, to form an aerosol for the user to inhale. The heating body 20 has a first heating zone 21 and a second heating zone 22, the first heating zone 21 and the second heating zone 22 being able to be raised to different temperatures in the case of simultaneous heating. The temperature of the first heating zone 21 may be higher than that of the second heating zone 22 or lower than that of the second heating zone 22. The heating body 20 located in the first heating region 21 and the second heating region 22 are made of different materials, and at least one of the first heating region 21 and the second heating region 22 can generate heat under the action of the alternating electromagnetic field.

Heating body 20 includes sensing portion 100 and filling portion 200, and sensing portion 100 may surround filling portion 200 in the whole circumferential direction, and of course, filling portion 200 may also surround sensing portion 100 in the whole circumferential direction, and sensing portion 100 and filling portion 200 are made of different materials. The induction part 100 is made of ferromagnetic material, so that the induction part 100 can generate heat under the action of the alternating electromagnetic field. The ferromagnetic material can be iron or a mixture of iron and other metals and non-metals, or can be cobalt, nickel, gadolinium, dysprosium, holmium and other metals or a mixture of the metals and other metals and non-metals. The ferromagnetic material may be either a conductor or an insulator. For example, the sensing part 100 may be made of a type 430 stainless steel material. The filling portion 200 may be made of ferromagnetic material, and the filling portion 200 may also be made of non-ferromagnetic material, such as ceramic, glass or metal. Of course, in the case that the filling part 200 is also made of a ferromagnetic material, the composition of the ferromagnetic material of the filling part 200 is different from that of the ferromagnetic material of the sensing part 100. Therefore, when the filling part 200 and the sensing part 100 are simultaneously made of ferromagnetic materials, both can generate heat under the action of the alternating electromagnetic field. In the present embodiment, the relationship between the sensing portion 100 and the first heating region is: the region covered by the sensing part 100 includes a first heating region 21, and the region not covered by the sensing part 100 includes a second heating region 22.

The heating body 20 can further comprise an electrode body 30, the heating body 20 is electrically connected with the electrode body 30, the electrode body 30 is used for electrically connecting a resistive film 31 arranged on the sensing part 100, the resistive film 31 is used for electrifying through the electrode body 30 and feeding back a resistance value, the temperature of the resistive film 31 is determined by the resistance value, the temperature of the resistive film 31 can be regarded as the temperature of the sensing part 100 or can be further regarded as sensing the temperature of the heating body 20, the phenomenon that the atomizing substrate is burnt and carbonized due to overhigh temperature of the heating body 20 is prevented, the phenomenon that the sucked aerosol is mixed with scorched smell and other unwanted gases is avoided, and the suction taste and the safety of the aerosol are improved. For example, when the resistive film 31 senses that the temperature of the heating body 20 is too high, the intensity of the alternating electromagnetic field may be appropriately reduced, thereby reducing the amount of heat generated by the heating body 20 per unit time, and finally, reasonably reducing the temperature of the heating body 20.

First embodiment

Referring to fig. 1 and 2, the heating body 20 has a sheet structure, and the heating body 20 includes a sensing part 100. The sensing portion 100 is formed with a slot 110, and the slot 110 is not filled with any substance such as a solid substance, i.e., the slot 110 is filled with air. The coverage area of the portion of the sensing part 100 not provided with the slot 110 includes the first heating area 21, and the coverage area of the slot 110 includes the second heating area 22. Obviously, the first heating area 21 is formed by being covered by a solid structure, and the second heating area 22 is formed by being covered by a dummy structure. The sensing portion 100 has two opposite surfaces 120 and a side circumferential surface connected between the two opposite surfaces 120, the two opposite surfaces 120 are located in a thickness direction of the sensing portion 100 and face opposite directions, the slot 110 has an opening on at least one of the opposite surfaces 220, and the slot 110 does not have an opening on the side circumferential surface, that is, the inner wall surface 111 of the slot 110 encloses a closed loop rather than an open loop structure, in a popular way, the slot 110 does not penetrate through the side circumferential surface of the sensing portion 100 and keeps a set distance from the side circumferential surface. For example, the slot 110 is a through hole, and there are openings on both opposite surfaces 120 of the slot 110; for another example, the slot 110 is a blind hole, and the slot 110 has an opening only on one of the opposite surfaces 120. Referring to fig. 1 and 2, the number of the slots 110 may be one, and referring to fig. 3 and 4, the number of the slots 110 may also be multiple, and the slots 110 are not communicated with each other and are spaced apart from each other and disposed on the sensing portion 100.

By forming the slot 110 on the sensing portion 100, it is obvious that the sensing portion 100 in the first heating region 21 can generate heat and raise the temperature, and the air in the second heating region 22 cannot generate heat itself, so that the second heating region 22 can only or mainly raise the temperature by absorbing the heat radiated by the first heating region 21, and therefore the first heating region 21 can simultaneously heat to a temperature higher than that of the second heating region 22. On the other hand, if the slot 110 is not formed in the inductor 100, it can be understood that the opened slot 110 is filled with the same ferromagnetic material as the inductor 100 outside the slot 110, and in this case, in view of the distribution rule of the alternating electromagnetic field on the heating body 20, the temperature of the inductor 100 at the slot 110 is higher than the temperature of the inductor 100 outside the slot 110 and the atomized substrate is charred, and the second heating region 22, which is "solid", is a high temperature region which is higher than the temperature of the first heating region 21 and the atomized substrate is charred. In this embodiment, the slot 110 is formed in the Gao Wenou region, and the "solid" second heating region 22 is converted into the "hollow" second heating region 22, so that the temperature of the region covered by the slot 110 is lower than the temperature of the sensing portion 100 outside the slot 110, that is, the temperature of the second heating region 22 is reduced to be lower than the temperature of the first heating region 21, because the air in the slot 110 cannot generate heat by itself and can only absorb the heat of the sensing portion 100 to raise the temperature, thereby eliminating the generation of a high temperature region capable of charring and carbonizing the atomized substrate on the heating body 20. At this time, the edge of the entire heating body 20 is relatively high in temperature with respect to the center. On the other hand, by arranging the slot 110, the redistribution of the alternating electromagnetic field on the induction part 100 can be adjusted, so that the thermal field distribution on the induction part 100 is changed, the temperature field distribution in the reasonable gradient arrangement is also provided in the first heating region 21, and the redistribution of the temperature field of the whole heating body 20 is ensured to meet new design and use requirements. On the other hand, the first heating area 21 is heated faster than the second heating area 22, and for a specific component in the atomized substrate, the specific component in the atomized substrate close to the first heating area 21 is rapidly atomized to form aerosol, and the specific component in the atomized substrate close to the second heating area 22 is relatively slowly atomized, so that the specific component is prevented from being atomized at the same time, that is, the concentration of the specific component in the aerosol is kept constant basically by enabling a specific component in the atomized substrate to have the sequence of successive atomization, and thus, the mouthfeel of the aerosol can be improved to a certain extent.

Second embodiment

Referring to fig. 5 and 6, the heating body 20 of the second embodiment is also a sheet-shaped structure, and the main difference from the heating body 20 of the first embodiment is that the slot 110 is filled with the filling portion 200 visible to the naked eye, in other words, the heating body 20 includes the sensing portion 100 and the filling portion 200, and the filling portion 200 is embedded in the sensing portion 100.

The filling portion 200 fills at least a portion of the slot 110, for example, the slot 110 may be a through hole penetrating through two opposite surfaces 120 in the thickness direction of the inductor 100, and the filling portion 200 may fill the entire slot 110, that is, fill the entire slot 110, in which case, the inductor 100 is disposed around the filling portion 200 in the entire circumferential direction. The surface of the filling portion 200 in the thickness direction and the surface 120 of the sensing portion 100 opposite to the filling portion may be flush with each other, and of course, the surface of the filling portion 200 in the thickness direction may be located inside the slot 110 or outside the slot 110, so that the surface of the filling portion 200 in the thickness direction and the surface 120 of the sensing portion 100 opposite to the filling portion in the thickness direction are spaced apart from each other in the thickness direction of the sensing portion 100. The filling part 200 may be made of a non-ferromagnetic material, at this time, a covering region where a portion of the sensing part 100 where the slot 110 is not disposed includes the first heating region 21, that is, a covering region covered by a portion of the sensing part 100 where the filling part 200 is not embedded includes the first heating region 21, and a covering region where the filling part 200 is disposed includes the second heating region 22, and obviously, the first heating region 21 is located in a region covered by an orthogonal projection of the sensing part 100 along the thickness direction of the heating body 20.

When the slot 110 is a through hole, the coverage area of the sensing part 100 includes the first heating area 21. The coverage area of the filling part 200 includes the second heating area 22.

When the filling part 200 is made of a non-ferromagnetic material, the filling part 200 cannot generate heat under the action of the alternating electromagnetic field, so that the filling part 200 absorbs the heat of the induction part 100 to increase the temperature, and thus the temperature of the first heating region 21 is higher than that of the second heating region 22. Therefore, if the filling part 200 is made of the same ferromagnetic material as the sensing part 100, and the entire heating body 20 is made of the same material, the distribution of the alternating magnetic field on the heating body 20 is different, which may cause the temperature of the second heating region 22 where the filling part 200 is located to be higher than that of the first heating region 21 where the sensing part 100 is located, thereby causing the phenomenon of scorching and carbonization of the atomized substrate. The filling part 200 of this embodiment is made of a material that cannot generate heat under the action of the alternating electromagnetic field, and the temperature of the second heating region 22 can be reduced reasonably, thereby eliminating the local high temperature that causes the atomized matrix to be charred and carbonized. At this time, the temperature of the edge of the entire heating body 20 is high with respect to the center. Meanwhile, the filling part 200 can also change the redistribution of the alternating electromagnetic field on the induction part 100, so that the induction part 100 forms temperature field distribution with reasonable gradient setting, and the temperature field of the whole heating body 20 is redistributed to meet new design and use requirements. And a certain specific component in the atomization substrate can be atomized in sequence, so that the concentration of the specific component in the aerosol is kept constant basically, and the mouthfeel of the aerosol is improved.

Of course, in other examples, the filling part 200 may be made of ferromagnetic material, so the filling part 200 itself may generate heat under the action of the alternating electromagnetic field, when the heat generated by the filling part 200 per unit time and unit area is relatively small, the temperature of the first heating region 21 is higher than that of the second heating region 22, and when the heat generated by the filling part 200 per unit time and unit area is relatively large, the temperature of the first heating region 21 is lower than that of the second heating region 22, and no matter how the temperatures of the first heating region 21 and the second heating region 22 change, it is only necessary to ensure the heating region with higher temperature to prevent the atomized matrix from being scorched and carbonized.

Third embodiment

Referring to fig. 7 and 8, the heating body 20 of the third embodiment is also of a sheet structure, and is mainly different from the second embodiment in that the filling portion 200 may be disposed around the sensing portion 100 in the entire circumferential direction, so that the sensing portion 100 is embedded in the filling portion 200.

The filling portion 200 has two opposite surfaces 220 facing opposite directions in a thickness direction thereof, the filling portion 200 is provided with a mounting hole 210 having an opening on at least one of the opposite surfaces 220, the mounting hole 210 is filled with the sensing portion 100, and a surface of the sensing portion 100 is flush with the opposite surfaces 220. The mounting hole 210 may be a through hole having openings on both opposite surfaces 220, at this time, the coverage area where the sensing portion 100 is located includes the first heating area 21, the coverage area where the portion of the filling portion 200 where the mounting hole 210 is not located includes the second heating area 22, that is, the area covered by the portion of the filling portion 200 where the sensing portion 100 is not embedded includes the second heating area 22.

When the mounting hole 210 is a through hole, the coverage area of the sensing part 100 includes the first heating area 21. The coverage area of the filling part 200 includes the second heating area 22.

When the filling part 200 is made of a non-ferromagnetic material, the filling part 200 itself cannot generate heat, and the filling part 200 absorbs the heat of the sensing part 100 to increase the temperature, so the temperature of the first heating region 21 is higher than that of the second heating region 22, and the temperature of the center of the entire heating body 20 is higher than that of the edge. The heating body 20 of this embodiment also eliminates localized high temperatures that can cause charring and carbonization of the atomized matrix, as compared to the case where the entire heating body 20 is made of the same ferromagnetic material. By arranging the filler 200 of non-ferromagnetic material around the induction part 100, it is also possible to form a temperature field distribution with a reasonable gradient arrangement for the induction part 100, ensuring that the temperature field of the heating body 20 is redistributed to meet new design and usage requirements. Of course, in other examples, the filling part 200 may be made of ferromagnetic material.

Fourth embodiment

Referring to fig. 9 and 10, the heating body 20 of the fourth embodiment is mainly different from the above-described heating body 20 in that the heating body 20 has a columnar structure.

The heating body 20 includes an induction portion 100 and a filling portion 200, the induction portion 100 is a columnar structure, the filling portion 200 is sleeved outside the induction portion 100, so that the induction portion 100 is wrapped inside the filling portion 200, that is, the filling portion 200 is disposed around the induction portion 100 in the whole circumferential direction, and the induction portion 100 is embedded in the filling portion 200. The axial length of the filling part 200 is greater than the axial length of the sensing part 100, the region covered by the orthogonal projection of the sensing part 100 along the axial direction of the heating body 20 (e.g., the radial direction of the heating body 20) includes a first heating region 21, and the region uncovered by the orthogonal projection of the sensing part 100 along the axial direction of the heating body 20 includes a second heating region 22. In other words, the region of filling unit 200 covered by the orthogonal projection of sensing unit 100 in the radial direction of heating body 20 includes first heating region 21, and the region of filling unit 200 not covered by the orthogonal projection of sensing unit 100 in the radial direction of heating body 20 includes second heating region 22. When the filling part 200 is made of a non-ferromagnetic material, the filling part 200 itself cannot generate heat under the action of the alternating electromagnetic field, and the temperature of the first heating area 21 is higher than that of the second heating area 22 because the first heating area 21 includes the sensing part 100. The heating body 20 of this embodiment also eliminates localized high temperatures that can cause charring and carbonization of the atomized matrix, as compared to the case where the entire heating body 20 is made of the same ferromagnetic material. It is also ensured that the temperature field of the heating body 20 is redistributed to meet new design and use requirements.

Fifth embodiment

Referring to fig. 11 and 12, the heating body 20 of the fifth embodiment is also of a cylindrical structure, and is mainly different from the fourth embodiment in that the induction part 100 is disposed around the filling part 200 in the entire circumferential direction.

The heating body 20 includes an induction part 100 and a filling part 200, the filling part 200 is a columnar structure, the induction part 100 is sleeved outside the filling part 200, and the axial length of the filling part 200 is greater than that of the induction part 100, so that a part of the filling part 200 is wrapped inside the induction part 100, that is, a part of the filling part 200 is embedded in the induction part 100. The region covered by the sensing part 100 includes a first heating region 21, and the region not covered by the sensing part 100 includes a second heating region 22. When the filling part 200 is made of a non-ferromagnetic material, the filling part 200 itself cannot generate heat under the action of the alternating electromagnetic field, and the temperature of the first heating area 21 is higher than that of the second heating area 22 because the first heating area 21 includes the sensing part 100. The heating body 20 of this embodiment also eliminates localized high temperatures that can cause charring and carbonization of the atomized matrix, as compared to the case where the entire heating body 20 is made of the same ferromagnetic material. It is also ensured that the temperature field of the heating body 20 is redistributed to meet new design and use requirements.

The invention also provides a heating and atomizing device which comprises a heater 10 and a main machine, wherein the main machine can generate an alternating electromagnetic field, and the heater 10 is arranged on the main machine and is positioned in the radiation range of the alternating electromagnetic field, so that the heater 10 can generate heat under the action of the alternating electromagnetic field, and the atomized substrate absorbs the heat to be atomized to form aerosol.
