[0044] In the prior art, the atomizer cores of most atomizers use ceramic heating units, including a cylindrical hollow ceramic liquid inlet and a metal heating element fixed to the inner wall of the ceramic liquid inlet. The aerosol matrix is ​​transported to the metal heating unit by the capillary action of the liquid suction holes on the ceramic liquid inlet, and the metal heating element heats the aerosol matrix to atomize it. Due to the inconsistency of the actual needs of each user, there is a need to adjust the heating power of the atomizer core to adjust the atomization volume during use. However, the conventional practice of some current atomizers is to adjust the voltage / current input to the atomizer core to increase the heating power of the atomizer core. However, this adjustment method cannot adjust the area of ​​the atomization area, cannot achieve accurate multi-level heating adjustment, and may also reduce the life of the atomizer core and cause the core to become sticky.

[0045] Based on this, in order to solve the above problems, the present application designs a heating element, by electrically connecting the first electrode and the second electrode on each heating element as the electrodes of the heating element to an external battery assembly, so that multiple heating elements are connected in parallel; by energizing different numbers of heating elements, it is possible to control a single heating element to heat alone, or to control multiple heating elements to heat at the same time; thereby effectively controlling the number of heating elements used to heat the atomized aerosol matrix, effectively adjusting the heating power of the heating element, and enabling the heating element to be adjusted in multiple gears.

[0046] An embodiment of the present application provides an atomizer (not shown), including a main body having a liquid storage cavity and an atomizing core 100 disposed in the liquid storage cavity.

[0047] Specifically, the atomizer is used in an electronic atomization device, which includes a power supply module, which includes a battery assembly. The battery assembly is used to be electrically connected to the atomization core 100. After the atomization core 100 is powered on, it is used to heat and atomize the aerosol matrix stored in the liquid storage chamber to generate an aerosol that can be inhaled by the user.

[0048] refer to Figure 2 、 Figure 3 、 Figure 4 In some embodiments, the atomizer core 100 includes a liquid inlet 3 and a heating element 1 .

[0049] Specifically, the liquid inlet 3 is a porous structure to satisfy the liquid guiding function. The aerosol matrix in the main body is connected to the heating element 1 through the liquid inlet 3. The heating element 1 is used to heat and atomize the aerosol matrix in contact with it.

[0050] refer to Figure 1 In some embodiments, the heating element 1 includes an electrode assembly 2 and a plurality of heating elements 4 having an arc-shaped sheet structure, each heating element 4 includes a first side end 401 and a second side end 402 relative to each other; the electrode assembly 2 includes a first electrode 201 and a plurality of second electrodes 202, the first side end 401 of each heating element 4 is connected to the first electrode 201, and the plurality of heating elements 4 are distributed circumferentially around the first electrode 201; the second side end 402 of each heating element 4 is connected to the second electrode 202.

[0051] Specifically, there are two or more heating elements 4, and each heating element 4 is independent of the other. By energizing the second electrode 202 and the first electrode 201 on any heating element 4, the heating element 4 can be controlled to generate heat individually. It can be understood that by electrically connecting the first electrode 201 and the second electrode 202 on each heating element 4 as electrodes of the heating element 1 to an external battery assembly, multiple heating elements 4 can be connected in parallel. By energizing different numbers of heating elements 4, the number of heating elements 4 used for heat generation can be controlled.

[0052] The heating element 1 of the present application has multiple heating elements 4 connected in parallel. By energizing different numbers of heating elements 4, it is possible to control a single heating element 4 to heat alone, or to control multiple heating elements 4 to heat simultaneously; thereby effectively controlling the number of heating elements 4 used to heat the atomized aerosol matrix, effectively adjusting the heating power of the heating element 1, and enabling the heating element 1 to be adjusted in multiple gears.

[0053] It can be understood that the first electrode 201 and the second electrode 202 can be but not limited to conductive connectors such as metal wires, metal plates, and thimbles; as long as the heating element 4 can be electrically connected to the external power supply component through the first electrode 201 and the second electrode 202.

[0054] refer to Figure 1 In some embodiments, the cross-sectional arc shape of the heating element 4 is a major arc.

[0055] Specifically, the heating element 4 is an arc sheet, and the cross-sectional shape of the heating element 4 is an arc. The arc is a superior arc, which has a longer arc length than the inferior arc, and can help increase the heating area of ​​a single heating element 4 and increase the heating power.

[0056] In some embodiments, the second side end 402 of any heating element 4 is spaced apart from the outer wall of the adjacent heating element 4 .

[0057] It can be understood that the second side end 402 of a single heating element 4 is spaced from the outer wall of the heating element 4 closest thereto and does not contact it, thereby avoiding a short circuit between two adjacent heating elements 4 .

[0058] refer to Figure 1 、 Figure 2 In some embodiments, the first electrode 201 includes a first lead 2011, which extends along the length direction (X direction in the figure) of the first side end 401 of the heating element 4; and the first side end 401 of each heating element 4 is respectively connected to the side wall surface of the first lead 2011.

[0059] Specifically, the first lead 2011 is a metal wire, and the first side end 401 of each heating element 4 is connected to the side wall of the first lead 2011. The first lead 2011 is flexible, which facilitates the first lead 2011 to be closely connected to the first side end 401 of each heating element 4, resulting in a tight connection. The first side ends 401 of each heating element 4 are circumferentially spaced around the first lead 2011, allowing the first lead 2011 to be electrically connected to multiple heating elements 4 simultaneously.

[0060] The first lead 2011 and the heating element 4 can be connected by welding, conductive adhesive, etc. For example, the preferred embodiment of the present invention is that the first lead 2011 and the heating element 4 are both made of metal and are connected by welding to ensure a stable structural connection.

[0061] It can be understood that at least one end of the first lead 2011 extends outward beyond the heating element 4 to facilitate connection of the first lead 2011 to an external power source.

[0062] Continue to refer Figure 1 、 Figure 2In some embodiments, the second electrode 202 includes a second lead 2021 , which extends along the length direction (X direction in the figure) of the second side end 402 of the heating element 4 , and at least one end of the second lead 2021 extends outwardly beyond the heating element 4 .

[0063] In some embodiments, the second lead 2021 and the first lead 2011 extend to the outside of the same side of the support body 5 .

[0064] Specifically, the first lead 2011 and the second lead 2021 extend out of the same side of the support body 5, which facilitates simultaneous electrical connection of the first lead 2011 and the second lead 2021 to an external power source, thereby facilitating assembly operations.

[0065] refer to Figure 1 In some embodiments, the number of the heating elements 4 is 3. The number of the heating elements 4 is set to a reasonable value. By setting 3 heating elements 4, three-level heating adjustment of low, medium and high can be achieved, and precise gear adjustment can be achieved.

[0066] refer to Figure 2 、 Figure 3 、 Figure 4 In some embodiments, the liquid inlet part 3 includes a support body 5, and the number of the support bodies 5 corresponds to the number of the heating bodies 4; each support body 5 is formed with a through-hole 6, and each heating body 4 of the heating element 1 is arranged one by one in the corresponding through-hole 6 of each support body 5.

[0067] It can be understood that the number of the supporting bodies 5 corresponds to the number of the heating bodies 4 , and one heating body 4 is correspondingly installed on the inner wall surface of one supporting body 5 .

[0068] Specifically, a single heating element 4 is stably disposed within the perforation 6 of a single support body 5. By providing multiple support bodies 5, the atomizer core 100 is structurally stable. Furthermore, each heating element 4 can independently heat and atomize the aerosol matrix within each support body 5, with comparable atomization rates. The inner wall of a single support body 5 can form an atomizing surface. By controlling the heating of different numbers of heating elements 4, the number of atomizing surfaces of the atomizer core 100 used for atomization can be controlled, thereby effectively adjusting the heating power of the atomizer core 100 and enabling accurate multi-level adjustment of the atomizer core 100.

[0069] refer to Figure 1 、 Figure 4 In some embodiments, the second electrode 202 is provided on the side wall surface of the heating element 4 facing the support body 5; the support body 5 is provided with an embedding groove 7 on the inner wall surface of the through hole 6, and the second electrode 202 is embedded in the embedding groove 7.

[0070] The support body 5 is provided with an embedding groove 7 on the inner wall surface of the through hole 6. The heating element 4 fits the inner wall surface of the support body 5 and the second electrode 202 is embedded in the embedding groove 7, so that the heating element 4 can be firmly connected to the support body 5 and the structure is tightly connected.

[0071] refer to Figure 2 、 Figure 3 、 Figure 4 In some embodiments, the support body 5 is a columnar structure, and two adjacent support bodies 5 are connected and enclosed to form a through-hole 6 .

[0072] Specifically, the support body 5 is a columnar structure, and the cross section of the support body 5 is in an arc shape; Figure 2 The two adjacent support bodies 5 are nested and connected with each other, and the two arcs of the two support bodies 5 on the cross section are intersecting, and the two support bodies 5 enclose to form a closed through-hole 6.

[0073] By connecting the supporting bodies 5 to each other, the structure is more stable and the overall volume of the liquid inlet part 3 can be reduced.

[0074] refer to Figure 3 、 Figure 4 In some embodiments, each support body 5 includes a first connection end 501 and a second connection end 502 relative to each other, the first connection end 501 of the support body 5 is connected to the first electrode 201, and the second connection end 502 of the support body 5 is connected to the outer wall of the adjacent support body 5.

[0075] Specifically, a plurality of support bodies 5 are nested in a ring-like manner to form the liquid inlet component 3 , which has a tight structural connection and can effectively reduce the overall volume of the liquid inlet component 3 .

[0076] It can be understood that the first connection end 501 of each support body 5 surrounds the first electrode 201 and can provide structural support to each heating element 4 at the center of the heating element 1, ensuring structural stability. In addition, the second connection end 502 of a single support body 5 is connected to the outer wall of the adjacent support body 5, making the structure between the support bodies 5 stable, and thus the liquid inlet member 3 as a whole has good structural stability.

[0077] In some embodiments, the supporting bodies 5 of the liquid inlet member 3 are integrally formed.

[0078] Specifically, the liquid inlet part 3 is a ceramic body, which is injection molded in a mold; and by positioning the heating element 1 in the mold, the liquid inlet part 3 forms an integrated whole with the heating element 1 during the molding process, and then the liquid inlet part 3 can better match the shape of the heating element 1, which can reduce the difficulty of assembly; after molding, each heating body 4 is tightly connected to the inner wall surface of each support body 5; and the liquid inlet part 3 is tightly combined with the heating element 1, and the structure is stable.

[0079] In some embodiments, the heating element 1 of the present application has three heating bodies 4, and the atomizer core 100 has three heating modes of low, medium, and high when heating and atomizing;

[0080] The low-speed heating mode is as follows: only the second electrode 202 on one heating element 4 is energized; and the three heating elements 4 are heated in a single cycle in sequence for a preset time, which can be, but is not limited to, 5 minutes, 10 minutes, 15 minutes, 20 minutes, etc. For example, the preset time is 10 minutes, that is, each heating element 4 is heated in a cycle, and each heating element 4 is heated for 10 minutes each time.

[0081] The mid-range heating mode is as follows: only the second electrodes 202 on two heating elements 4 are energized; the three heating elements 4 are grouped into three groups, two each; and the three groups of heating elements 4 are energized in a cycle for 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, meaning that the three groups of heating elements 4 are heated in a cycle, with each group of heating elements 4 being heated for 10 minutes.

[0082] Then, the use of a circulating heating mode can effectively increase the service life of the atomizer core, avoid long-term power heating of a heating element 4, reduce the occurrence of core sticking, and improve the taste.

[0083] The high-speed heating mode is: the second electrodes 202 on the three heating elements 4 are energized at the same time; that is, the three heating elements 4 are heated at the same time.

[0084] The above are only 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 principles of the present application should be included in the scope of protection of the present application.
