[0039] The present application is described in detail below with reference to the accompanying drawings and optional embodiments.

[0040] Figure 1 is a schematic diagram of an electronic atomization device according to an embodiment of the present application. Figure 1 As shown, the present application discloses an electronic atomization device 10, which includes a control component 100 and an electronic atomizer 200. The control component 100 is connected to the electronic atomizer 200 to control the electronic atomizer 200 to generate aerosol.

[0041] The control component 100 includes a component housing 110, a partition 120 and a control circuit board 130. The partition 120 is arranged in the component housing 110 to divide the internal space of the component housing 110 into a circuit board space portion 140 and an electronic atomizer space portion 150; the control circuit board 130 is arranged in the circuit board space portion 140, and the electronic atomizer 200 is partially arranged in the electronic atomizer space portion 150.

[0042] Exemplarily, when the control component 100 of the electronic atomization device 10 provides power to the electronic atomizer 200 in a charging manner, a battery is also provided in the circuit board accommodating cavity, and the battery is connected to the control circuit board 130; of course, when the control component 100 uses an external power supply to provide power to the electronic atomizer 200, the circuit board of the control component 100 is directly connected to the external power supply through a power cord, which is not limited here.

[0043] The present application also discloses an electronic atomizer 200, which can be used in the electronic atomization device 10 described above. With respect to the electronic atomizer 200, the present application provides the following embodiments:

[0044] Embodiment 1:

[0045] Figure 2 is an exploded schematic diagram of an electronic atomizer according to the first embodiment of the present application, Figure 3 is a schematic diagram of an electronic atomizer according to the first embodiment of the present application. Figure 2-3As shown, the present application discloses an electronic atomizer 200, which includes a liquid cup shell 210, a liquid cup base 220 and an atomizer core 300, wherein the liquid cup shell 210 is sleeved on the liquid cup base 220, and the atomizer core 300 is arranged between the liquid cup shell 210 and the liquid cup base 220, and the liquid cup base 220, the liquid cup shell 210 and the atomizer core 300 jointly define a liquid storage tank 240, and the liquid storage tank 240 is used to store an aerosol matrix, and the atomizer core 300 includes an atomizer shell 310 and an atomizer assembly 320, and the atomizer assembly 320 is partially arranged in the atomizer shell 310.

[0046] The electronic atomizer 200 further includes a preheating structure 400 , which is electrically connected to the atomization assembly 320 and is at least partially located in the liquid storage tank 240 for preheating the aerosol matrix stored in the liquid storage tank 240 .

[0047] The electrical connection between the preheating structure 400 and the atomizing assembly 320 simply means that the atomizing assembly 320 and the preheating structure 400 are directly connected. When the atomizing assembly 320 is powered on, the preheating structure 400 will also be powered on synchronously with the atomizing assembly 320.

[0048] The electronic atomizer 200 also includes an air inlet 250, an air outlet 211, and an atomizing air passage 311. The air outlet 211 is arranged on the liquid cup shell 210, and the air inlet 250 is arranged on the liquid cup base 220. The interior of the atomizing shell 310 is hollow to form the atomizing air passage 311; the air inlet 250, the atomizing air passage 311 and the air outlet 211 are connected in sequence to form an aerosol passage.

[0049] Illustratively, when the electronic atomizer 200 is working, external gas enters the atomization airway 311 from the air inlet 250 , and the aerosol generated by the atomization assembly 320 heating the aerosol matrix is ​​brought out from the air outlet 211 .

[0050] Compared with the electronic atomizer 200 that does not have a preheating structure 400, the present application sets a preheating structure 400 directly connected to the atomizer component 320 in the liquid storage tank 240. When the electronic atomizer 200 is working, the atomizer component 320 is heated to generate aerosol, and the preheating structure 400 can preheat the aerosol matrix in the liquid storage tank 240, thereby increasing the flow rate of the aerosol matrix in the liquid storage tank 240, so that the aerosol matrix can flow to the atomizer component 320 faster, thereby reducing the risk of dry burning of the heating plate 322, and allowing the aerosol matrix entering the atomizer component 320 to be converted into aerosol faster, thereby accelerating the speed of generating aerosol to a certain extent.

[0051] Moreover, compared with the solution of setting up a separately controlled heating structure, since the preheating structure 400 is electrically connected to the atomization component 320, no separate control is required. When the atomization component 320 starts heating, the preheating structure 400 can also start preheating synchronously, thereby simplifying the structure of the electronic atomizer 200.

[0052] The atomizing housing 310 is hollow inside to form an atomizing airway 311. The atomizing housing 310 is provided with a liquid inlet hole 312. The liquid inlet hole 312 connects the liquid storage tank 240 and the atomizing airway 311. The atomizing assembly 320 includes a liquid-conducting cotton 321, a heating sheet 322 and a heating lead 323. The liquid-conducting cotton 321 is attached to the inner wall of the atomizing housing 310 and is located at the liquid inlet hole 312 of the atomizing airway 311. The heating sheet 322 is attached to the side of the liquid-conducting cotton 321 away from the inner wall of the atomizing housing 310. The heating lead 323 is electrically connected to the heating sheet 322. The preheating structure 400 is connected to one end of the heating lead 323 away from the heating sheet 322. The preheating structure 400 is directly connected to the heating lead 323 of the atomizing assembly 320.

[0053] Among them, the preheating structure 400 can be a separately set structure, such as a preheating plate, a preheating wire, etc.; this embodiment takes the preheating structure 400 as a preheating wire as an example, and the preheating wire is prepared together with the heating lead 323, that is, the preheating structure 400 and the heating lead 323 are integrally formed.

[0054] In this way, it is only necessary to extend the heating lead 323 when producing the atomization component 320, and then extend the extended part into the liquid storage tank 240 as the preheating structure 400. There is no need to set up the preheating structure 400 separately, thereby avoiding the problem of unstable connection between the preheating structure 400 and the heating lead 323 and reducing the difficulty of assembly.

[0055] Moreover, in order to further improve the preheating effect, the heating lead 323 of the present application includes a positive lead 324 and a negative lead 325, and the positive lead 324 and the negative lead 325 are both connected to the heating sheet 322; the preheating structure 400 includes a first sub-preheating structure 410 and a second sub-preheating structure 420, and the first sub-preheating structure 410 is connected to one end of the positive lead 324 away from the heating sheet 322; the second sub-preheating structure 420 is connected to one end of the negative lead 325 away from the heating sheet 322.

[0056] The first sub-preheating structure 410 is integrally formed with the positive electrode lead 324 , and the second sub-preheating structure 420 is integrally formed with the negative electrode lead 325 .

[0057] In simple terms, the first sub-preheating structure 410 and the second sub-preheating structure 420 are respectively arranged at the ends of the positive lead 324 and the negative lead 325 to increase the number of preheating structures 400, thereby improving the preheating effect of the aerosol matrix in the liquid storage tank 240.

[0058] In order to prevent the preheating structure 400 from overheating and causing direct atomization of the aerosol matrix in the liquid storage tank 240, the present application also sets the resistance of the preheating structure 400 to be smaller than the resistance of the heating plate 322, thereby ensuring that the heat generated by the preheating structure 400 is smaller than the heat generated by the heating plate 322. Specifically, the cross-sectional area of ​​the preheating structure 400 can be thickened to reduce the resistance value of the preheating structure 400.

[0059] Figure 4 is a schematic diagram of a liquid inlet hole in the first embodiment of the present application, such as Figure 4 As shown, the opening of the liquid inlet hole 312 is arranged toward the preheating structure 400. In short, the preheating structure 400 is arranged at the opening of the liquid inlet hole 312, so that the preheating structure 400 can directly preheat the aerosol matrix that will enter the liquid-conducting cotton 321 from the liquid inlet hole 312, thereby improving the efficiency of preheating.

[0060] Figure 5 is a schematic diagram of another air inlet of the first embodiment of the present application, such as Figure 5 As shown, in addition to the air inlet hole 250 provided on the liquid cup base 220 , the air inlet hole 250 may be provided on the electrode column 500 .

[0061] Specifically, the electronic atomizer 200 also includes a base rubber coating 230, and the base rubber coating 230 is arranged between the liquid cup base 220 and the liquid cup shell 210. A gap is set between the base rubber coating 230 and the liquid cup base 220, and a base space portion 260 is formed between the base rubber coating 230 and the liquid cup base 220, and the atomization airway 311 is connected to the base space portion 260.

[0062] The electrode column 500 is hollow inside to form an electrode column air channel 530. The end of the electrode column air channel 530 away from the liquid cup housing 210 is an air inlet 250. The electrode column air channel 530 is connected to the base space 260. The air inlet 250, the electrode column air channel 530, the atomization air channel 311 and the air outlet 211 are connected in sequence to form the aerosol channel.

[0063] Illustratively, when the electronic atomizer 200 is working, external gas enters the electrode column airway 530 from the air inlet 250 , enters the atomization airway 311 through the base space 260 , and brings the aerosol generated by the atomization component 320 heating the aerosol matrix out from the air outlet 211 .

[0064] Compared with the solution of setting the air inlet hole 250 on the base, by setting the electrode column air channel 530 in the electrode column 500, the external gas enters the electronic atomizer 200 through the electrode column air channel 530, which can prevent the condensed liquid formed by the cooling of the aerosol from flowing to the outside through the air inlet hole 250 on the liquid cup base 220.

[0065] Embodiment 2:

[0066] Figure 6 is a schematic diagram of an electronic atomizer according to the second embodiment of the present application. Figure 6 As shown, different from the first embodiment, the preheating structure 400 of the present application is connected to the electrode column 500, specifically:

[0067] The interior of the atomizing shell 310 is hollow to form an atomizing airway 311, and a liquid inlet hole 312 is provided on the atomizing shell 310, and the liquid inlet hole 312 connects the liquid storage tank 240 and the atomizing airway 311; the atomizing assembly 320 includes a liquid guiding cotton 321, a heating sheet 322 and a heating lead 323, the liquid guiding cotton 321 is attached to the inner wall of the atomizing shell 310 and is located at the liquid inlet hole 312 of the atomizing airway 311, the heating sheet 322 is attached to the side of the liquid guiding cotton 321 away from the inner wall of the atomizing shell 310, and the heating lead 323 is electrically connected to the heating sheet 322.

[0068] The atomization assembly 320 also includes an electrode column 500, one end of which is arranged on the side of the liquid cup base 220 away from the liquid cup shell 210, and the other end passes through the liquid cup base 220 and is electrically connected to the heating lead 323; the preheating structure 400 is connected to the end of the electrode column 500 away from the liquid cup base 220, and the preheating structure 400 and the electrode column 500 are integrally formed.

[0069] In simple terms, this embodiment extends the length of the electrode column 500, and extends the extended portion of the electrode column 500 into the liquid storage tank 240 as a preheating structure 400. Compared with the first embodiment in which the extended portion of the heating lead 323 is used as the preheating structure 400, this embodiment does not need to bend the extended portion, and assembly is also simpler.

[0070] The resistance of the electrode column 500 is smaller than the resistance of the heating sheet 322 , thereby preventing the preheating structure 400 from being overheated and causing the aerosol matrix in the liquid storage tank 240 to be directly atomized.

[0071] In order to further improve the preheating efficiency, the two electrode columns 500 are lengthened in this embodiment. Specifically, the heating lead 323 includes a positive lead 324 and a negative lead 325, and the positive lead 324 and the negative lead 325 are both connected to the heating sheet 322; the electrode column 500 includes a first sub-electrode column 510 and a second sub-electrode column 520, one end of the first sub-electrode column 510 is arranged on the side of the liquid cup base 220 away from the liquid cup shell 210, and the other end is connected to the end of the positive lead 324 away from the heating sheet 322; one end of the second sub-electrode column 520 is arranged on the side of the liquid cup base 220 away from the liquid cup shell 210, and the other end is connected to the end of the negative lead 325 away from the heating sheet 322.

[0072] The preheating structure 400 includes a first sub-preheating structure 410 and a second sub-preheating structure 420, wherein the first sub-preheating structure 410 is connected to one end of the first sub-electrode column 510 away from the liquid cup housing 210; the second sub-preheating structure 420 is connected to one end of the second sub-electrode column 520 away from the liquid cup housing 210; the first sub-preheating structure 410 and the first sub-electrode column 510 are integrally formed, and the second sub-preheating structure 420 and the second sub-electrode column 520 are integrally formed; in short, the present embodiment also provides two preheating structures 400, thereby improving the preheating efficiency and accelerating the speed at which the electronic atomizer 200 generates aerosol.

[0073] The resistance of the first sub-electrode column 510 and the second sub-electrode column 520 are both smaller than the resistance of the heating sheet 322 , thereby preventing the preheating structure 400 from overheating and causing the aerosol matrix in the liquid storage tank 240 to boil.

[0074] Furthermore, in this embodiment, an air inlet hole 250 may be provided on the liquid cup base 220 , or may be provided on the electrode column 500 , which is the same as the first embodiment and will not be described in detail herein.

The steps written in front can be executed first, or later, or even simultaneously. As long as this solution can be implemented, it should be deemed to fall within the scope of protection of this application.

[0076] It should be noted that the inventive concept of this application can form a great number of embodiments, but the length of the application document is limited and it is impossible to list them one by one. Therefore, under the premise of no conflict, the embodiments or technical features described above can be arbitrarily combined to form new embodiments.
