[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0033] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0034] See also Figure 1 and Figure 5The heater 10 provided by the present invention includes a heating body 20, which can be used to heat a solid block or strip atomization matrix. The atomization matrix is ​​specifically an aerosol generating matrix. When heated, the atomization matrix 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 area 21 and a second heating area 22. When heated at the same time, the first heating area 21 and the second heating area 22 can be raised to different temperatures. The temperature of the first heating area 21 can be greater than the temperature of the second heating area 22, or less than the temperature of the second heating area 22. The materials included in the heating body 20 located in the first heating area 21 and the second heating area 22 are different, 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.

[0035] 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 circumference. Of course, the filling part 200 can also be arranged around the induction part 100 in the entire circumference. The induction part 100 and the filling part 200 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 an alternating electromagnetic field. The ferromagnetic material can be a mixture of iron or iron with other metals and non-metals, or a mixture of metals such as cobalt, nickel, gadolinium, dysprosium and holmium or such metals with other metals and non-metals. The ferromagnetic material can be either a conductor or an insulator. For example, the induction part 100 can be made of 430 stainless steel material. 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, when 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 the filling part 200 and the induction part 100 are both made of ferromagnetic material, both can generate heat under the action of the alternating electromagnetic field. In this embodiment, the relationship between the induction part 100 and the first heating area is: the area covered by the induction part 100 includes the first heating area 21, and the area not covered by the induction part 100 includes the second heating area 22.

[0036] The heating body 20 may also include an electrode body 30, and the heating body 20 is electrically connected to the electrode body 30. The electrode body 30 is used to electrically connect to a resistor film 31 disposed on the sensing part 100. The resistor film 31 is used to energize through the electrode body 30 and feedback the resistance value. The temperature of the resistor film 31 is determined by the resistance value. Since the resistor film 31 is disposed on the sensing part 100, the temperature of the resistor film 31 can be regarded as the temperature of the sensing part 100, and can also be further regarded as sensing the temperature of the heating body 20, so as to prevent the heating body 20 from being too high in temperature and causing the atomized matrix to be burnt and carbonized, and to avoid the aerosol being mixed with burnt smell and other unnecessary gases, thereby improving the aerosol suction taste and safety. For example, when the resistor 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 reasonably reducing the temperature of the heating body 20.

[0037] First embodiment

[0038] See also Figure 1 and Figure 2 The heating body 20 is a sheet structure, and the heating body 20 includes a sensing part 100. The sensing part 100 is provided with a slot 110, and the slot 110 is not filled with any substance such as solid substance, that is, the slot 110 is filled with air. The covering area where the portion of the sensing part 100 where the slot 110 is not provided includes a first heating area 21, and the covering area where the slot 110 is provided includes a second heating area 22. Obviously, the first heating area 21 is formed by covering a solid structure, and the second heating area 22 is formed by covering a virtual structure. The sensing part 100 has two opposing surfaces 120 and a lateral surface 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 opposite directions. The slot 110 has an opening on at least one opposing surface 220, and the slot 110 does not have an opening on the lateral surface, that is, the inner wall surface 111 of the slot 110 forms a closed loop rather than an open loop structure. In layman's terms, the slot 110 does not penetrate the lateral surface of the sensing part 100 but maintains a set distance from the lateral surface. For example, the slot 110 is a through hole, and there are openings on both opposing surfaces 120 of the slot 110; for another example, the slot 110 is a blind hole, and there is an opening on only one opposing surface 120 of the slot 110. See Figure 1 and Figure 2 The number of the slot 110 may be one, see Figure 3 and Figure 4 The number of the slots 110 may also be multiple, and the multiple slots 110 are not connected to each other but are arranged at intervals on the sensing part 100.

[0039] 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 by itself, and the air in the second heating area 22 cannot generate heat by itself, resulting in the second heating area 22 can only or mainly absorb the heat radiated by the first heating area 21 to heat up, so the first heating area 21 can be heated to a temperature greater than the second heating area 22 at the same time. On the one hand, if the induction part 100 is not provided with the slot 110, it can be understood that the slot 110 that has been opened is filled with the same ferromagnetic material as the induction part 100 outside the slot 110. At this time, in view of the distribution law of the alternating 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 matrix to be charred and carbonized. It can be understood that the "solid" second heating area 22 is a high temperature area with a temperature higher than the first heating area 21 and causes the atomized matrix to be charred and carbonized. This embodiment, by opening a slot 110 in the above-mentioned high-temperature area, converts the "solid" second heating area 22 into a "hollow" second heating area 22. Since the air in the slot 110 cannot generate heat by itself but can only absorb the heat of the sensing part 100 to heat up, the temperature of the area covered by the slot 110 is lower than the temperature of the sensing part 100 outside the slot 110, that is, the temperature of the second heating area 22 is reduced to a temperature lower than that of the first heating area 21, thereby eliminating the high-temperature area on the heating body 20 that can cause the atomized matrix to be charred and carbonized. At this time, the edge of the entire heating body 20 is higher in temperature than the center. On the other hand, by providing the slot 110, the redistribution of the alternating electromagnetic field on the sensing part 100 can be adjusted, thereby changing the thermal field distribution on the sensing part 100, so that the first heating area 21 also has a temperature field distribution with a reasonable gradient setting, ensuring that the temperature field of the entire heating body 20 is redistributed to meet new design and use requirements. On the other hand, the first heating region 21 heats up faster than the second heating region 22. For a specific component in the atomized matrix, the specific component in the atomized matrix near the first heating region 21 is quickly atomized to form an aerosol, while the specific component in the atomized matrix near the second heating region 22 is atomized relatively slowly, thereby avoiding the specific components from being atomized at the same time. That is, by making a specific component in the atomized matrix have a sequence of sequential atomization, the concentration of the specific component in the aerosol is ensured to remain basically constant, which can improve the taste of the aerosol to a certain extent.

[0040] Second embodiment

[0041] See also Figure 5 and Figure 6The heating body 20 of the second embodiment is also a sheet-like structure. The main difference from the heating body 20 of the first embodiment is that the slot 110 is filled with a filling portion 200 visible to the naked eye. In other words, the heating body 20 includes a sensing portion 100 and a filling portion 200, and the filling portion 200 is embedded in the sensing portion 100.

[0042] The filling part 200 fills at least part of the slot 110. For example, the slot 110 may be a through hole that penetrates the two opposite surfaces 120 in the thickness direction of the sensing part 100. The filling part 200 may fill the entire slot 110, that is, fill the entire slot 110. At this time, the sensing part 100 is arranged around the filling part 200 in the entire circumference. The surface of the filling part 200 in the thickness direction may be flush with the opposite surface 120 of the sensing part 100. Of course, the surface of the filling part 200 in the thickness direction may be located inside the slot 110 or outside the slot 110, so that the surface of the filling part 200 in the thickness direction and the opposite surface 120 of the sensing part 100 are spaced apart along the thickness direction of the sensing part 100. The filling part 200 can be made of non-ferromagnetic material. In this case, the coverage area of ​​the portion of the sensing part 100 where the slot 110 is not set includes the first heating area 21, that is, the area covered by the portion of the sensing part 100 where the filling part 200 is not embedded includes the first heating area 21, and the coverage area where the filling part 200 is located includes the second heating area 22. Obviously, the first heating area 21 is located within the area covered by the orthographic projection of the sensing part 100 along the thickness direction of the heating body 20.

[0043] When the slot 110 is a through hole, the coverage area of ​​the induction portion 100 includes the first heating area 21 , and the coverage area of ​​the filling portion 200 includes the second heating area 22 .

[0044] 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 area 21 is higher than the temperature of the second heating area 22. Therefore, if the filling part 200 is made of the same ferromagnetic material as the induction part 100, the entire heating body 20 is made of the same material. Due to the different distribution of the alternating magnetic field on the heating body 20, the second heating area 22 where the filling part 200 is located can produce a temperature greater than the first heating area 21 where the induction part 100 is located, thereby causing the atomized matrix to produce a charred carbonization phenomenon. 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 area 22 can be reasonably reduced, thereby eliminating the local high temperature that causes the atomized matrix to produce charred carbonization. At this time, the temperature of the edge of the entire heating body 20 is higher than 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 sensing part 100, so that the sensing 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 design and use requirements. It can also make a certain component in the atomized matrix have a sequence of atomization, ensuring that the concentration of the specific component in the aerosol remains basically constant, thereby improving the taste of the aerosol.

[0045] Of course, in other examples, the filling portion 200 can be made of ferromagnetic material, so the filling portion 200 itself can generate heat under the action of the alternating electromagnetic field. When the heat generated by the filling portion 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 portion 200 per unit time and per unit area is relatively large, the temperature of the first heating area 21 is lower than the temperature of the second heating area 22. No matter how the temperatures of the first heating area 21 and the second heating area 22 change, it is only necessary to ensure that the heating area with a higher temperature prevents the atomized matrix from being burned and carbonized.

[0046] Third embodiment

[0047] See also Figure 7 and Figure 8 The heating body 20 of the third embodiment is also a sheet-like structure. The main difference from the second embodiment is that the filling portion 200 can be arranged around the induction portion 100 in the entire circumference, so that the induction portion 100 is embedded in the filling portion 200 .

[0048] The filling part 200 has two opposite surfaces 220 located in the thickness direction thereof and facing oppositely. The filling part 200 is provided with a mounting hole 210 with an opening on at least one of the opposite surfaces 220. The sensing part 100 fills the mounting hole 210, and the surface of the sensing part 100 is flush with the opposite surfaces 220. The mounting hole 210 may be a through hole with openings on both opposite surfaces 220. In this case, the coverage area where the sensing part 100 is located includes the first heating area 21, and the coverage area where the portion of the filling part 200 where the mounting hole 210 is not provided includes the second heating area 22, that is, the area covered by the portion of the filling part 200 where the sensing part 100 is not embedded includes the second heating area 22.

[0049] When the mounting hole 210 is a through hole, the coverage area of ​​the induction part 100 includes the first heating area 21 , and the coverage area of ​​the filling part 200 includes the second heating area 22 .

[0050] 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 and heats up, so the temperature of the first heating area 21 is higher than the temperature of the second heating area 22, and the temperature of the center of the whole heating body 20 is higher than the edge. Compared with the whole heating body 20, which is all made of the same ferromagnetic material, the heating body 20 of this embodiment can also eliminate the local high temperature that can cause the atomized matrix to be charred and carbonized. By surrounding the induction part 100 with the filling part 200 of non-ferromagnetic material, the induction part 100 can also form a temperature field distribution with a reasonable gradient setting, ensuring that the temperature field of the heating body 20 is redistributed and meets the new design and use requirements. Of course, in other examples, the filling part 200 can also be made of ferromagnetic material.

[0051] Fourth embodiment

[0052] See also Fig. 9 and Fig.10 The main difference between the heating body 20 of the fourth embodiment and the above-mentioned heating body 20 is that the heating body 20 is a columnar structure.

[0053] The heating body 20 includes a sensing part 100 and a filling part 200. The sensing part 100 is a columnar structure. The filling part 200 is sleeved outside the sensing part 100, so that the sensing part 100 is covered inside the filling part 200, that is, the filling part 200 is arranged around the sensing part 100 in the entire circumferential direction, and the sensing part 100 is embedded in the filling part 200. The axial length of the filling part 200 is greater than the axial length of the sensing part 100. The area covered by the orthographic projection of the sensing part 100 along the axial direction of the heating body 20 (for example, the radial direction of the heating body 20) includes a first heating area 21, and the area not covered by the orthographic projection of the sensing part 100 along the axial direction of the heating body 20 includes a second heating area 22. In other words, the area of ​​the filling part 200 covered by the orthographic projection of the sensing 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 sensing part 100 along the radial direction of the heating body 20 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 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 temperature of the second heating area 22. Compared with the entire heating body 20 made of the same ferromagnetic material, the heating body 20 of this embodiment can also eliminate the local high temperature that can cause the atomized matrix to be charred and carbonized. It also ensures that the temperature field of the heating body 20 is redistributed to meet the new design and use requirements.

[0054] Fifth embodiment

[0055] See also Fig.11 and Fig.12 The heating body 20 of the fifth embodiment is also a columnar structure, and the main difference from the fourth embodiment is that the induction part 100 is arranged around the filling part 200 in the entire circumference.

[0056] 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 the axial length of the induction part 100, so that a part of the filling part 200 is covered within the induction part 100, that is, a part of the filling part 200 is embedded in the induction part 100. The area covered by the induction part 100 includes the first heating area 21, and the area not covered by the induction part 100 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 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 temperature of the second heating area 22. Compared with the entire heating body 20 made of the same ferromagnetic material, the heating body 20 of this embodiment can also eliminate the local high temperature that can cause the atomized matrix to produce charring and carbonization. It also ensures that the temperature field of the heating body 20 is redistributed to meet the new design and use requirements.

[0057] The present invention also provides a heating atomization device, which includes a heater 10 and a main unit. The main unit can generate an alternating electromagnetic field. The heater 10 is arranged on the main unit and is located within the radiation range of the alternating electromagnetic field. In this way, the heater 10 can generate heat under the action of the alternating electromagnetic field, so that the atomization matrix absorbs the heat to atomize and form an aerosol.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
