It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. 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 similar expressions are used herein for the purpose of description only and do not represent the only embodiment.

Referring to Fig. 1 and Fig. 5, the heater 10 provided by the present invention includes a heating body 20, and the heating body 20 can be used to heat a solid block or strip atomized substrate, and the atomized substrate is specifically an aerosol generating substrate , when the atomized base is heated, it can atomize some of its added components such as aroma components to form an aerosol that can be inhaled by the user. The heating body 20 has a first heating region 21 and a second heating region 22 which, in the case of simultaneous heating, can be raised to different temperatures. The temperature of the first heating area 21 can be higher than the temperature of the second heating area 22 or lower than the temperature of the second heating area 22 . The heating body 20 located in the first heating area 21 and the second heating area 22 includes different materials, and at least one of the first heating area 21 and the second heating area 22 can generate heat under the action of an alternating electromagnetic field.

The heating body 20 includes an induction part 100 and a filling part 200. The induction part 100 can be arranged around the filling part 200 in the entire circumferential direction. Of course, the filling part 200 can also be arranged around the induction part 100 in the entire circumferential direction. The induction part 100 and the filling part 200 Both are made of different materials. The induction part 100 is made of ferromagnetic material, so the induction part 100 can generate heat under the action of the alternating electromagnetic field. Ferromagnetic materials can be iron or a mixture of iron and other metals and nonmetals, or metals such as cobalt, nickel, gadolinium, dysprosium and holmium, or a mixture of such metals and other metals and nonmetals. Ferromagnetic materials can be either conductors or insulators. For example, the sensing part 100 can be made of 430 type stainless steel. The filling part 200 can be made of ferromagnetic material, and the filling part 200 can 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 ferromagnetic material, the composition of the ferromagnetic material of the filling part 200 is different from the composition of the ferromagnetic material of the induction part 100 . Therefore, when both the filling part 200 and the induction part 100 are made of ferromagnetic materials, both can generate heat under the action of an alternating electromagnetic field. In this embodiment, the relationship between the sensing part 100 and the first heating area is: the area covered by the sensing part 100 includes the first heating area 21 , and the area not covered by the sensing part 100 includes the second heating area 22 .

The heating body 20 may also include an electrode body 30, the heating body 20 is electrically connected to the electrode body 30, the electrode body 30 is used to electrically connect the resistance film 31 arranged on the induction part 100, and the resistance film 31 is used to conduct electricity through the electrode body 30 and The resistance value is fed back, and the temperature of the resistance film 31 is determined by the resistance value. Since the resistance film 31 is arranged on the sensing part 100, the temperature of the resistance film 31 can be regarded as the temperature of the sensing part 100, and can also be further regarded as a sensing heating body The temperature of 20 degrees prevents the heating body 20 temperature from being too high to cause charring and carbonization of the atomized substrate, prevents the aerosol being sucked from being mixed with burnt smell and other unnecessary gases, and improves the taste and safety of the aerosol suction . For example, when the resistance film 31 senses that the temperature of the heating body 20 is too high, the intensity of the alternating electromagnetic field can be appropriately reduced, thereby reducing the heat generated by the heating body 20 per unit time, and finally reducing the temperature of the heating body 20 reasonably.

first embodiment

Referring to FIG. 1 and FIG. 2 , the heating body 20 is a sheet structure, and the heating body 20 includes an induction part 100 . A slot 110 is opened on the sensing part 100 , and the slot 110 is not filled with any substance such as a solid substance, that is, the slot 110 is filled with air. The coverage area of the induction part 100 without the slot 110 includes the first heating area 21 , and the coverage area of the slot 110 includes the second heating area 22 . Apparently, the first heating area 21 is formed by covering the solid structure, while the second heating area 22 is formed by covering the virtual structure. The sensing part 100 has two opposing surfaces 120 and side peripheral surfaces connected between the two opposing surfaces 120. The two opposing surfaces 120 are located in the thickness direction of the sensing part 100 and face oppositely. The slot 110 is in at least one There is an opening on the opposite surface 220, and the slot 110 does not have an opening on the side peripheral surface, that is, the inner wall surface 111 of the slot 110 forms a closed loop rather than an open loop structure. Generally speaking, the slot 110 does not penetrate to the The side peripheral surface of the sensing part 100 maintains a set distance from the side peripheral surface. For example, the slot 110 is a through hole, and there are openings on both opposite surfaces 120 of the slot 110 ; as another example, the slot 110 is a blind hole, and the slot 110 only has openings on one opposite surface 120 . Referring to Fig. 1 and Fig. 2, the number of slots 110 can be one, referring to Fig. 3 and Fig. 4, the number of slots 110 can also be multiple, and the plurality of slots 110 are not communicated with each other and arranged at intervals in the sensing part 100 on.

By opening the slot 110 on the induction part 100, it is obvious that the induction part 100 in the first heating area 21 can generate heat and heat up, and the air in the second heating area 22 cannot generate heat by itself, so that the second heating area 22 can only generate heat. The temperature can be increased mainly by absorbing the heat radiated by the first heating region 21 , so the first heating region 21 can be heated to a temperature higher than that of the second heating region 22 at the same time. On the one hand, if no slot 110 is opened on the induction part 100, it can be understood that the above-mentioned opened slot 110 is filled with the same ferromagnetic material as the induction part 100 outside the slot 110. At this time, in view of the alternating The distribution law of the electromagnetic field on the heating body 20, the temperature of the induction part 100 located at the slot 110 will be higher than the temperature of the induction part 100 outside the slot 110 and cause the atomized substrate to burn and carbonize, which can be understood as " The "solid" second heating zone 22 is a high-temperature zone that is higher than the temperature of the first heating zone 21 and causes the atomized substrate to burn and carbonize. In this embodiment, the "solid" second heating region 22 is converted into a "hollow" second heating region 22 by opening the slot 110 in the above-mentioned high temperature region. It can absorb the heat of the induction part 100 and heat up, so that the temperature of the area covered by the slot hole 110 is lower than the temperature of the induction part 100 outside the slot hole 110, that is, the temperature of the second heating area 22 is reduced to be lower than that of the first heating area 21 temperature, thereby eliminating the high-temperature area on the heating body 20 that can cause the atomized substrate to burn and carbonize. At this time, the temperature of the edge of the entire heating body 20 is higher than that of the center. On the other hand, by setting the slot 110, the redistribution of the alternating electromagnetic field on the induction part 100 can be adjusted, thereby changing the distribution of the thermal field on the induction part 100, so that the first heating region 21 also has a temperature field with a reasonable gradient setting distribution, to ensure that the temperature field of the entire heating body 20 is redistributed to meet new design and use requirements. On the other hand, the temperature rise of the first heating zone 21 is relatively fast relative to the second heating zone 22. For the specific component in the atomized substrate, the specific component in the atomized substrate close to the first heating zone 21 is quickly atomized to An aerosol is formed, and the specific component in the atomized matrix close to the second heating zone 22 is atomized relatively slowly, avoiding the simultaneous atomization of the specific component, that is, by making a certain specific component in the atomized matrix have a sequence The order of atomization ensures that the concentration of the specific component in the aerosol remains basically constant, which can improve the taste of the aerosol to a certain extent.

second embodiment

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

The filling part 200 fills at least part of the slot 110. For example, the slot 110 can be a through hole that runs through the two opposite surfaces 120 in the thickness direction of the sensing part 100. The filling part 200 can fill the entire slot 110, that is, fill the entire slot 110. , at this time, the induction part 100 is disposed around the filling part 200 in the entire circumferential direction. The surface in the thickness direction of the filling part 200 can be flush with the opposite surface 120 of the sensing part 100. Of course, the surface in the thickness direction of the filling part 200 can be located inside the slot 110 or outside the slot 110, so that the filling The surface in the thickness direction of the sensing part 200 is spaced from the opposite surface 120 of the sensing part 100 along the thickness direction of the sensing part 100 . The filling part 200 can be made of non-ferromagnetic material. At this time, the covered area where the part of the induction part 100 is not provided with the slot hole 110 includes the first heating area 21, that is, the part of the induction part 100 where the filling part 200 is not embedded. The covered area includes the first heating area 21, and the covered area where the filling part 200 is located includes the second heating area 22. Obviously, the first heating area 21 is located in the area covered by the orthographic projection of the induction part 100 along the thickness direction of the heating body 20. within.

When the slot 110 is a through hole, the covered area of the induction 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 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 and heats up, so the temperature of the first heating region 21 is higher than The temperature of the second heating zone 22. Therefore, if the filling part 200 is made of the same ferromagnetic material as the induction part 100, so that the entire heating body 20 is made of the same material, since the distribution of the alternating magnetic field on the heating body 20 is different, the filling part 200 The second heating region 22 where the temperature is higher than that of the first heating region 21 where the induction part 100 is located will cause the atomized substrate to be charred and carbonized. In this embodiment, the filling part 200 is made of materials that cannot generate heat under the action of an alternating electromagnetic field, which can reasonably reduce the temperature of the second heating area 22, thereby eliminating the local high temperature that causes charring and carbonization of the atomized substrate. At this time, the temperature of the edge of the entire heating body 20 is higher than that of the center. At the same time, the setting of 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 a temperature field distribution with a reasonable gradient setting, ensuring that the temperature field of the entire heating body 20 is redistributed to meet the new requirements. design and use requirements. And it can also make a specific component in the atomized matrix have a sequential atomization sequence, so as to ensure that the concentration of the specific component in the aerosol is basically kept constant, thereby improving the taste of the aerosol.

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

third embodiment

Referring to Fig. 7 and Fig. 8, the heating body 20 of the third embodiment is also a sheet structure, and the main difference from the above-mentioned second embodiment is that the filling part 200 can be arranged around the induction part 100 in the entire circumferential direction, so that the induction part 100 Embedded in the filling part 200 .

The filling part 200 has two facing opposite surfaces 220 located in its thickness direction. The filling part 200 is provided with a mounting hole 210 with an opening on at least one of the facing surfaces 220. The sensing part 100 fills the mounting hole 210. The sensing part The surface of 100 and the opposite surface 220 are flush with each other. The installation hole 210 can be a through hole with openings on both opposite surfaces 220. At this time, the covered area where the induction part 100 is located includes the first heating area 21, and the part where the filling part 200 is not provided with the installation hole 210 is located. The area includes the second heating area 22 , that is, the area covered by the part of the filling part 200 not embedded with the induction part 100 includes the second heating area 22 .

When the mounting hole 210 is a through hole, the coverage area of the induction 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 non-ferromagnetic material, the filling part 200 itself cannot generate heat, and the filling part 200 absorbs the heat of the induction part 100 to heat up, so the temperature of the first heating area 21 is higher than the temperature of the second heating area 22 , at this time the temperature of the center of the entire heating body 20 is higher than that of the edge. Compared with the entire heating body 20 being made of the same ferromagnetic material, the heating body 20 of this embodiment can also eliminate the local high temperature that can cause charring and carbonization of the atomized substrate. By arranging the filling part 200 of non-ferromagnetic material around the induction part 100, the temperature field distribution with a reasonable gradient setting can also be formed in the induction part 100, ensuring that the temperature field of the heating body 20 is redistributed to meet new design and use requirements . Of course, in other examples, the filling part 200 may also be made of ferromagnetic material.

The axial length of the filling part 200 is greater than the axial length of the induction part 100, and the area covered by the orthographic projection of the induction part 100 along the axis perpendicular to the heating body 20 (such as the radial direction of the heating body 20) includes the first heating area 21, and the induction The area not covered by the orthographic projection of the portion 100 along the axial direction perpendicular to the heating body 20 includes the second heating area 22 . In other words, the area of the filling part 200 covered by the orthographic projection of the induction part 100 along the radial direction of the heating body 20 includes the first heating area 21, and the area of the filling part 200 not covered by the orthographic projection of the induction part 100 along the radial direction of the heating body 20 A second heating zone 22 is included. When the filling part 200 is made of non-ferromagnetic material, the filling part 200 itself cannot generate heat under the action of the alternating electromagnetic field, and the first heating area 21 includes the induction part 100, so the temperature of the first heating area 21 is higher than the second The temperature of the heating zone 22. Compared with the entire heating body 20 being made of the same ferromagnetic material, the heating body 20 of this embodiment can also eliminate the local high temperature that can cause charring and carbonization of the atomized substrate.
