[0003] Due to the inconsistent actual needs of each user, there is a need to adjust the heating power of the atomization core to adjust the atomization amount during use; however, for some current atomizers, due to the relatively simple structure of the metal heating element, only by changing the magnitude of the voltage / current input to the atomization core can the heating power of the atomization core be adjusted and increased. However, this adjustment method cannot adjust the atomization area, cannot achieve accurate multi-gear heating adjustment, and may also reduce the service life of the atomization core and cause the possibility of core coking.

[0015] By adopting the above technical solution, side plates are arranged on the substrate, and the heating bodies are connected to the side plates, improving the connection stability between the heating bodies and the substrate and enhancing the structural reliability.

[0016] In some embodiments, the number of the heating bodies is 2, 3 or 4.

[0017] By adopting the above technical solution, multi-gear adjustment of the heating element is realized by setting the number of the heating bodies.

[0018] In some embodiments, the first electrode body, the plurality of heating bodies and the plurality of second electrode bodies are integrally processed and formed.

[0019] By adopting the above technical solution, the first electrode body, the plurality of second electrode bodies and the plurality of second electrode bodies are integrally processed and formed by a metal plate through chemical etching, stamping, laser / mechanical engraving and other methods. The structural integrity is good; and there is no need to weld leads.

By controlling the number of electrified heating bodies, accurate multi-gear power adjustment of the atomization core can be achieved. Moreover, by arranging the heating bodies on the outer side surface of the liquid inlet body, on the basis of the same volume of the liquid inlet body, compared with the prior art method of arranging the heating bodies on the inner wall surface of the liquid inlet body, it is obvious that the total area of the atomization surface can be increased, and then the atomization core can atomize more aerosol matrix per unit time, thereby improving the atomization efficiency of the atomization core and increasing the heating power of the atomization core.

[0022] In some embodiments, the liquid inlet body is in the shape of a straight prism to form a plurality of the outer side surfaces, and the number of the outer side surfaces is equal to the number of the heating bodies; each heating body is correspondingly arranged on each outer side surface.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0046] In the present application, unless otherwise clearly defined and limited, the terms "installed", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0048] In the prior art, the atomizing cores of most atomizers adopt ceramic heating elements, including a ceramic liquid inlet main body with a cylindrical hollow structure and a metal heating element fixed on the inner wall surface of the ceramic liquid inlet main body. The shape of the metal heating element matches the shape of the inner wall surface of the ceramic liquid inlet main body. The aerosol matrix is transported to the metal heating element by the capillary action of the liquid suction holes on the ceramic liquid inlet main body, and the metal heating element heats the aerosol matrix to atomize it. Since the actual needs of each user are inconsistent, there is a need to adjust the heating power of the atomizing core to adjust the atomization amount during use. However, due to the relatively simple structure of the metal heating element in some current atomizers, only the voltage / current input to the atomizing core can be changed to adjust and increase the heating power of the atomizing core. This adjustment method cannot adjust the atomization area, cannot achieve accurate multi-stage heating adjustment, and may also reduce the service life of the atomizing core and cause the possibility of core coking.

[0049] Based on this, to solve the above problems, the present application designs a heating element. The first electrode body and the second electrode bodies on each heating element are respectively electrically connected to an external power supply as the electrodes of the atomizing core, so that a parallel connection is formed between multiple heating elements. By energizing different numbers of heating elements, it is possible to control a single heating element to heat alone or control multiple heating elements to heat simultaneously, and accurate multi-stage adjustment of the heating element can be achieved.

[0050] An embodiment of the present application provides an atomizer (not shown). The atomizer includes a housing storing an aerosol matrix and an atomizing core 1000 disposed in the housing. The atomizing core 1000 is used to heat and atomize the aerosol matrix stored in the housing to generate an aerosol for users to inhale.

[0051] The atomizer is applied to an electronic atomization device. The electronic atomization device further includes a battery assembly. The power supply assembly has a battery module for supplying power to the atomizing core 1000.

[0052] Reference Figure 4 、 Figure 5 、 Figure 6 , in some embodiments, the atomizing core 1000 includes a liquid inlet main body 2 and a heating element 1. The liquid inlet main body 2 is in the shape of a straight prism. The liquid inlet main body 2 has opposite top surfaces 3, bottom surfaces 4, and outer side surfaces 5 connecting the top surface 3 and the bottom surface 4. The liquid inlet main body 2 has an inner cavity 6, and the inner cavity 6 forms an opening 7 on the top surface 3 or the bottom surface 4. The heating element 1 is disposed outside the liquid inlet main body 2.

[0053] Understandably, an opening 7 is formed on the top surface 3, and the aerosol matrix in the housing enters the inner cavity 6 of the liquid inlet body 2 under the action of gravity through the opening 7; the bottom surface 4 of the liquid inlet body 2 is hermetically closed, that is, the inner cavity 6 in the liquid inlet body 2 can store the aerosol matrix. The outer side surface 5 of the liquid inlet body 2 is a porous structure, and the porous structure forms a capillary action to transport the aerosol matrix in the inner cavity 6 to the outer side surface 5 of the liquid inlet body 2; the heating element 1 is energized to effectively heat and atomize the aerosol matrix.

[0054] Reference Figure 1 、 Figure 2 、 Figure 3 , in some embodiments, the heating element 1 includes a plurality of heating bodies 101 and a first electrode body 8 that is electrically connected to the same end of each heating body 101; a second electrode body 9 is respectively provided at one end of each heating body 101 away from the first electrode body 8.

[0055] Specifically, the heating element 1 and the liquid inlet body 2 are combined to form an atomization core 1000. The first electrode body 8 of the heating element 1 is provided on the top surface 3 or the bottom surface 4, and each heating body 101 is provided on the outer side surface 5.

[0056] Understandably, the heating element 1 is a metal body. The first electrode body 8 and the second electrode bodies 9 on each heating body 101 are respectively used as the electrodes of the atomization core 1000 and are electrically connected to an external battery module so that a parallel connection is formed between the plurality of heating bodies 101. The number of heating bodies 101 is two or more. By energizing different numbers of heating bodies 101, that is, it is possible to control a single heating body 101 to heat alone or control multiple heating bodies 101 to heat simultaneously; thus, the number of heating bodies 101 used to heat and atomize the aerosol matrix can be effectively controlled, enabling the heating element 1 to accurately perform multi-stage adjustment.

[0057] In some embodiments, the number of heating bodies 101 can be, but is not limited to, 2, 3, or 4; the liquid inlet body 2 is prismatic or cylindrical, which is not specifically limited herein. By arranging the heating bodies 101 on the outer side surface 5 of the liquid inlet body 2, adjacent two heating bodies 101 do not contact each other, so that multiple outer side surfaces 5 of the liquid inlet body 2 form multiple atomization surfaces that can be used to heat and atomize the aerosol matrix, and each atomization surface can be heated independently.

[0058] In one example, the liquid inlet body 2 is triangular prism-shaped and has three outer side surfaces 5. Heating elements 101 are respectively provided on all four outer side surfaces 5 of the liquid inlet body 2. Subsequently, the atomization core 1000 has three heating gears, that is, it can control only the heating element 101 on one of the outer side surfaces 5 to be powered on for heating; alternatively, it can control the heating elements 101 on two of the outer side surfaces 5 to be powered on for heating; or, it can control the heating elements 101 on three of the outer side surfaces 5 to be powered on for heating. Single-sided heating, double-sided heating or three-sided heating can be achieved. The more the number of the heating elements 101 powered on for heating, the greater the heating power of the atomization core 1000, and the more atomized gas is generated.

[0059] In another example, the liquid inlet body 2 is quadrangular prism-shaped and has four outer side surfaces 5. Heating elements 101 are respectively provided on all four outer side surfaces 5 of the liquid inlet body 2. Subsequently, the atomization core 1000 has four heating gears, namely single-sided heating, double-sided heating, three-sided heating or four-sided heating.

[0060] In still another example, the liquid inlet body 2 can also be cylindrical and has one outer side surface 5. Each heating element 101 is arranged on the outer side surface 5 of the liquid inlet body 2 along the circumferential direction, and each heating element 101 is in contact with the outer side surface 5.

[0061] For the atomization core 1000 of the present application, by respectively arranging heating elements 101 capable of being independently powered on for heating on multiple outer side surfaces 5 of the liquid inlet body 2, that is, multiple independent atomization surfaces for atomizing the aerosol matrix are formed on the liquid inlet body 2. By controlling the number of the heating elements 101 powered on, the atomization core 1000 has different gears such as single-sided heating, double-sided heating and multi-sided heating, and can accurately adjust the power of the atomization core 1000 in multiple gears, effectively adjusting the heating power of the atomization core 1000; improving the taste and meeting the needs of customers in different states.

[0062] Moreover, by arranging the heating elements 101 on the outer side surface 5 of the liquid inlet body 2, on the basis of the same volume of the liquid inlet body 2, compared with the prior art method of arranging the heating elements 101 on the inner wall surface of the liquid inlet body 2, it can significantly increase the total area of the atomization surface. Subsequently, the atomization core 1000 can atomize more aerosol matrix per unit time, thereby improving the atomization efficiency of the atomization core 1000 and increasing the heating power of the atomization core 1000.

[0063] Reference Figure 1 、 Figure 2 、 Figure 3 In some embodiments, the first electrode body 8 includes a substrate 801. The substrate 801 is formed with an electrical contact surface 10 for abutting against an external power supply; the substrate 801 is connected to each heating element 101.

[0064] Understandably, the substrate 801 has electrical conductivity, and each heating element 101 is respectively connected to the substrate 801 to achieve electrical conduction, enabling the substrate 801 to be connected to an external power supply as one of the electrodes of each heating element 101.

[0065] Specifically, the substrate 801 is disposed on the top surface 3 or the bottom surface 4 of the liquid inlet body 2, having good structural stability; and an electrical contact surface 10 is formed on the end surface of the substrate 801 away from the liquid inlet body 2, that is, the substrate 801 is electrically connected to an external power supply device in a surface contact manner, which is convenient and fast for connection. Understandably, the battery module in the electronic atomization device is correspondingly provided with a surface contact conductive element, and the circuit is conducted through the contact between the surface contact conductive element and the electrical contact surface 10 of the substrate 801.

[0066] Reference Figure 1 、 Figure 2 In some embodiments, the first electrode body 8 further includes a plurality of side plates 802 vertically disposed on the substrate 801; the side plates 802 are used for connecting to the heating element 101.

[0067] Understandably, the side plates 802 extend along the substrate 801 toward the side close to the liquid inlet body 2, and the heating element 101 is connected to the side plates 802, improving the connection stability between the heating element 101 and the substrate 801; then the substrate 801 can be stably connected to each heating element 101, enhancing the structural reliability.

[0068] Reference Figure 2 、 Figure 4 In some embodiments, the second electrode body 9 includes a plug-in board 901 disposed at the end of the heating element 101 away from the first electrode body 8, and the plug-in board 901 extends along the lengthwise direction of the liquid inlet body 2.

[0069] Specifically, the second electrode body 9 is of an insertion type structure and is electrically connected to an external power supply by plugging the plug-in board 901, with a relatively large contact point and low energy consumption. Then there is no need to weld leads on the heating element 101, saving the welding steps.

[0070] Understandably, after the heating element 1 is combined with the liquid inlet body 2, the plug-in board 901 extends outwards beyond the bottom surface 4, facilitating the plugging of the heating element 1 into an external power supply.

[0071] Reference Figure 4 In some embodiments, the heating element 101 includes a plurality of intersecting and connected heating wires and meshes formed between the heating wires, and the meshes are circular, oval, triangular or polygonal.

[0072] Understandably, the heating element 101 is a mesh heating element (i.e., Mesh heating mesh), which is a heating element made of a metal plate or metal tube with mesh holes in various different patterns, and the resistance value and heat concentration degree of the heating element are adjusted by controlling the pattern size and shape; it is a heating element commonly used in the current atomization core 1000.

[0073] Reference Figure 1 、 Figure 2 , specifically, the mesh holes of the heating element 101 are rhombus-shaped.

[0074] Reference Figures 1 - 3 , in some embodiments, the first electrode body 8, the plurality of heating elements 101, and the plurality of second electrode bodies 9 are integrally processed and formed.

[0075] Specifically, the first electrode body 8, the heating element 101, and the second electrode body 9 of the present application are all metal structures, and both the first electrode body 8 and the second electrode body 9 are plate-shaped structures; then the heating element 1 as a whole can be formed by chemically etching, stamping, laser / mechanical engraving, etc. on a whole metal plate to form the first electrode body 8, the heating element 101, and the second electrode body 9, with good structural integrity and stability.

[0076] Reference Figures 4 - 6 , in some embodiments, the number of the heating elements 101 is three, the liquid inlet main body 2 is in the shape of a regular triangular prism, and the liquid inlet main body 2 has three outer side surfaces 5; the three heating elements 101 are respectively arranged on the three outer side surfaces 5.

[0077] Specifically, the preferred embodiment of the present application is that the liquid inlet main body 2 is in the shape of a regular triangular prism, that is, the areas of the outer side surfaces 5 of the liquid inlet main body 2 tend to be equal; the heating element 1 correspondingly has three heating elements 101 arranged on the outer side surfaces 5, and then the atomization core 1000 forms three atomization surfaces. The atomization core 1000 can realize single-sided heating, double-sided heating, and three-sided heating, and can accurately adjust between three gears of low, medium, and high, with reasonable gear settings; and the heating power of the heating elements 101 on the outer side surfaces 5 is the same when heating, so when the gear is switched, the heating power can increase or decrease step by step.

[0078] In some embodiments, reference Figure 7 , when the liquid inlet main body 2 is in the shape of a straight prism, the assembly method of the atomization core 1000 and the atomizer is: the atomizer includes a cylinder 12 arranged in the main body, and the cylinder 12 is arranged outside the liquid inlet main body 2; the edges of the liquid inlet main body 2 are in contact with the inner wall surface of the cylinder 12; and a plurality of atomization channels 11 are formed by enclosing between the liquid inlet main body 2 and the cylinder 12.

[0079] Understandably, a cylinder 12 is provided inside the main body of the atomizer. The atomization core 1000 is installed inside the cylinder 12, and the cylinder 12 is used to play a certain role in blocking the temperature of the atomization core 1000 during the atomization process. The cylinder 12 has a cylindrical structure, and the inner diameter of the cylinder 12 is matched with the liquid inlet main body 2, so that the liquid inlet main body 2 is arranged inside the cylinder 12 and the edges of the liquid inlet main body 2 are in contact with the inner wall surface of the cylinder 12.

[0080] In some embodiments, the liquid inlet main body 2 is in interference fit with the cylinder 12, that is, there is stress between the edges of the liquid inlet main body 2 and the inner wall surface of the cylinder 12, and the liquid inlet main body 2 is stably arranged inside the cylinder 12. The cylinder 12 is made of metal, and the edges of the liquid inlet main body 2 are in contact with the inner wall surface of the cylinder 12. Then, the heating element 101 on the outer side surface 5 of the liquid inlet main body 2 will not be in contact with the cylinder 12, avoiding the occurrence of a short - circuit phenomenon.

[0081] Reference Figure 6 , a plurality of independent atomization channels 11 are formed by enclosing between the liquid inlet main body 2 and the cylinder 12, and each atomization channel 11 corresponds to one of the outer side surfaces 5 of the liquid inlet main body 2; when the heating element 101 on one of the outer side surfaces 5 of the liquid inlet main body 2 is electrified and heated, this outer side surface 5 forms an atomization surface for heating and atomizing the aerosol matrix, and the aerosol generated by this atomization surface will be released into the corresponding atomization channel 11 and conducted inside the atomizer through the atomization channel 11.

[0082] In some embodiments, the liquid inlet main body 2 is a regular triangular prism, and the liquid inlet main body 2 has three outer side surfaces 5. Then, three atomization channels 11 are formed by enclosing between the liquid inlet main body 2 and the cylinder 12; the atomization core 1000 has three independent and non - interfering heating regions, and the atomization core 1000 can preferably achieve single - side heating, double - side heating, and triple - side heating.

[0083] Reference Figure 1 、 Figure 3 、 Figure 4 , in some embodiments, an opening 7 is formed on the top surface 3, a first electrode body 8 is arranged on the top surface 3, and a window 13 for avoiding the opening 7 is provided on the first electrode body 8.

[0084] Understandably, setting the window 13 on the substrate 801 of the first electrode body 8 does not affect the aerosol matrix from entering the opening 7; and setting the window 13 can also reduce the weight of the substrate 801, thereby reducing the overall weight of the atomization core 1000, achieving a two - birds - with - one - stone effect.

[0085] Reference Figure 3 、 Figure 4, in some embodiments, the liquid inlet body 2 is a ceramic liquid inlet body, and the liquid inlet body 2 is formed in a mold; and the liquid inlet body 2 is combined with the heating element 1 in the mold during the forming process. Then, after forming, the first electrode body 8 is tightly connected to the top surface 3 of the liquid inlet body 2, and the heating body 101 is tightly connected to the outer side surface 5 of the liquid inlet body 2; the connection between the heating element 1 and the liquid inlet body 2 is tight and stable, and the structural stability is good.

[0086] In some embodiments, the heating element 1 of the present application has three heating bodies 101, and the atomization core 1000 has low, medium, and high heating modes during heating and atomization;

[0087] The low heating mode is: the three heating bodies 101 will be heated individually in a single cycle in sequence according to a preset duration. The preset duration can be, but is not limited to, 5 minutes, 10 minutes, 15 minutes, 20 minutes, etc. For example, the preset duration is 10 minutes, that is, each heating body 101 is heated in a cycle, and the heating duration of each heating body 101 each time is 10 minutes.

[0088] The medium heating mode is: every two of the three heating bodies 101 form a group, and a total of three groups can be divided; the three groups of heating bodies 101 are sequentially energized in a cycle according to a preset duration; the preset duration can be, but is not limited to, 5 minutes, 10 minutes, 15 minutes, 20 minutes, etc. For example, the preset duration is 10 minutes, that is, the three groups of heating bodies 101 are heated in a cycle, and the heating duration of each group of heating bodies 101 each time is 10 minutes.

[0089] Then, adopting a cycle heating mode can effectively improve the service life of the atomization core, avoid long-term power-on heating of a single heating body 101, reduce the occurrence of the phenomenon of the core getting burned, and improve the use taste.

[0090] The high heating mode is: the second electrode bodies 9 on the three heating bodies 101 are simultaneously energized.

[0091] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
