[0041] The present application is described in detail below with reference to the accompanying drawings and optional embodiments.

[0042] 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 battery assembly 20 and an electronic atomizer 300 , and the electronic atomizer 300 is connected to the battery assembly 20 .

[0043] The battery assembly 20 includes an assembly housing 210, a partition 220 and a control circuit board 230. The partition 220 is arranged in the assembly housing 210 to divide the internal space of the assembly housing 210 into a circuit board space portion 250 and an atomizer space portion 260; the control circuit board 230 is arranged in the circuit board space portion 250, and the electronic atomizer 300 is partially arranged in the atomizer space portion 260.

[0044] The electronic atomization device 10 further includes a microphone 231 , which is disposed on the control circuit board 230 , and an air inlet of the microphone 231 is disposed on the partition 220 . The microphone 231 controls the operation of the control circuit board 230 by sensing changes in air pressure.

[0045] Exemplarily, when the power supply component of the electronic atomization device 10 provides power to the electronic atomizer 300 in a charging manner, a battery is also provided in the circuit board space portion 250, and the battery is connected to the control circuit board 230; of course, when the power supply component uses an external power supply to provide power to the electronic atomizer 300, the circuit board of the power supply component is directly connected to the external power supply through a power cord, which is not limited here.

[0046] The present application also discloses an electronic atomizer 300, which can be used in the electronic atomization device 10 described above. For the electronic atomizer 300, the present application provides the following design:

[0047] Figure 2 is a schematic diagram of an explosion of an electronic atomizer according to an embodiment of the present application. Figure 3 is a schematic diagram of a first air inlet of an electronic atomizer according to an embodiment of the present application, such as Figure 2-3 As shown, Figure 3 The direction indicated by the middle arrow is the flow direction of part of the gas. The present application discloses an electronic atomizer 300 for generating aerosol in cooperation with a battery assembly 20 .

[0048] The electronic atomizer 300 includes a base 400, a liquid cup shell 500, and an atomizer core 440; the liquid cup shell 500 is sleeved on the base 400, and the atomizer core 440 is arranged between the liquid cup shell 500 and the base 400. The base 400, the liquid cup shell 500 and the atomizer core 440 together define a liquid storage tank 600.

[0049] The electronic atomizer 300 also includes an electrode column 700, one end of which is located on the side of the base 400 away from the liquid cup shell 500, and is used to connect to the control circuit board 230 in the battery assembly 20, and the other end passes through the base 400 and is connected to the liquid cup shell 500. The atomization core 440 is electrically connected to the electrode column 700, and an electrode channel 750 is provided in the electrode column 700.

[0050] The electronic atomizer 300 further includes an atomization channel 441, a first air inlet 510 and an air outlet 530. The atomization channel 441 runs through the atomization core 440. The first air inlet 510 is arranged on the side wall of the liquid cup housing 500. The air outlet 530 is arranged at one end of the liquid cup housing 500 away from the base 400. The first air inlet 510, the electrode channel 750, the atomization channel 441 and the air outlet 530 are sequentially connected to form an aerosol channel 800. The atomization core 440 is provided with a liquid inlet 442, and the liquid inlet 442 conducts the liquid storage tank 600 and the atomization channel 441. The electronic atomizer 300 further includes a base rubber coating 430, which is arranged between the base 400 and the atomization core 440.

[0051] When the atomizer core 440 starts working, the aerosol matrix in the liquid storage tank 600 will enter the atomizer core 440 from the liquid inlet hole 442 on the atomizer core 440, and the atomizer core 440 will heat the aerosol matrix to generate aerosol in the atomization channel 441, while the external gas enters the electronic atomizer 300 from the first air inlet hole 510, and comes to the atomization channel 441 through the electrode channel 750, and brings the aerosol in the atomization channel 441 out of the electronic atomizer 300 through the air outlet hole 530.

[0052] Compared with the existing electronic atomizer 300, the first air inlet hole 510 is generally set on the base 400, which will cause the aerosol matrix condensate to leak out from the first air inlet hole 510. However, the present application sets the first air inlet hole 510 on the side wall of the liquid cup shell 500. In this way, there is no need to set the first air inlet hole 510 on the base 400, so that the aerosol matrix condensate will not leak out.

[0053] Moreover, compared with the general solution in which the first air inlet 510 is arranged on the side wall of the liquid cup shell 500, and the air passage formed on the liquid cup shell 500, the atomization channel 441 and the air outlet 530 are directly connected in sequence, the present application arranges an electrode channel 750 in the electrode column 700, which can reduce the difficulty of preparing the liquid cup shell 500 and improve the preparation yield, and the electrode column 700 can also heat the external gas to increase the circulation speed of the gas.

[0054] Specifically: the number of the electrode columns 700 includes at least two, namely a first electrode column 710 and a second electrode column 720, one end of the first electrode column 710 is located on the side of the base 400 away from the liquid cup shell 500, and the other end penetrates the base 400 and is connected to the liquid cup shell 500, one end of the second electrode column 720 is located on the side of the base 400 away from the liquid cup shell 500, and the other end penetrates the base 400 and is connected to the liquid cup shell 500, and the first electrode column 710 is electrically connected to the positive electrode of the atomizer core 440, and the second electrode column 720 is electrically connected to the negative electrode of the atomizer core 440; the electrode channel 750 is provided in both the first electrode column 710 and the second electrode column 720.

[0055] The number of the first air inlet holes 510 includes at least two, namely a first sub-air inlet hole 511 and a second sub-air inlet hole 512. The first sub-air inlet hole 511 and the second sub-air inlet hole 512 are both arranged on the side wall of the liquid cup housing 500, and the first sub-air inlet hole 511 and the second sub-air inlet hole 512 are arranged opposite to each other.

[0056] The first sub-air inlet hole 511, the electrode channel 750 in the first electrode column 710, the atomization channel 441 and the air outlet hole 530 are connected in sequence to form the aerosol channel 800; the second sub-air inlet hole 512, the electrode channel 750 in the second electrode column 720, the atomization channel 441 and the air outlet hole 530 are connected in sequence to also form the aerosol channel 800.

[0057] In short, the present application sets electrode channels 750 in two electrode columns 700 in the electronic atomizer 300, namely the first electrode column 710 and the second electrode column 720, and correspondingly sets two first air inlet holes 510, which are the first sub-air inlet hole 511 and the second sub-air inlet hole 512, respectively. This greatly increases the flow rate of external gas entering the electronic atomizer 300, thereby generating more aerosol.

[0058] Furthermore, the electrode column 700 is at least partially located in the liquid storage tank 600 . The liquid storage tank 600 is used to place an aerosol matrix, and the outer wall of the electrode column 700 is in contact with the aerosol matrix.

[0059] When the electronic atomizer 300 is working, the electrode column 700 will generate heat, and the heat can be transferred to the aerosol matrix in the liquid storage tank 600, thereby heating the aerosol matrix. On the one hand, it increases the flow rate of the aerosol matrix transmitted to the atomization core 440, and on the other hand, it allows the aerosol matrix to reach the boiling point faster after being transmitted to the atomization core 440, making it easier to generate more aerosol and improve the user experience.

[0060] The existing electronic atomizer 300 needs to set a protrusion on the outer wall of the base 400 and a groove on the inner wall of the liquid cup shell 500, and fix the liquid cup shell 500 and the base 400 together by snapping the protrusion and the groove. This will cause the connecting surface between the liquid cup shell 500 and the outer wall of the base 400 to not fit tightly, thereby causing the problem of leakage of the aerosol matrix.

[0061] In the present application, one end of the electrode column 700 close to the base 400 is riveted to the base 400, and the other end penetrates the base 400 and is connected to the liquid cup shell 500 by interference fit. Thus, the flatness of the outer wall of the liquid cup shell 500 and the base 400 is ensured, thereby avoiding the problem of leakage of aerosol matrix and improving the user experience.

[0062] Among them, the assembly method of the electronic atomizer 300 is as follows: step 1: riveting the electrode column 700 to the base 400; step 2: assembling the atomizer core 440 to the base rubber bag 430; step 3: assembling the base rubber bag 430 equipped with the atomizer core 440 into the base 400 installed with the electrode column 700; step 4: covering the liquid cup shell 500 on the base 400.

[0063] Figure 4 This is a schematic diagram of the cooperation between the second air inlet of an electronic atomizer and a battery assembly according to an embodiment of the present application, combined with Figure 2 and Figure 4 As shown, Figure 4 The direction indicated by the arrow is the flow direction of part of the gas. The present application makes a corresponding design for the scheme of controlling the start and stop of the control circuit board 230 through the microphone 231, that is, a second air inlet 520 is provided on the side wall of the liquid cup housing 500, as follows:

[0064] The battery assembly 20 includes an assembly housing 210, a partition 220 and a microphone 231. The partition 220 is arranged in the assembly housing 210 to divide the internal space of the assembly housing 210 into a circuit board space portion 250 and an atomizer space portion 260. The electronic atomizer 300 is partially arranged in the atomizer space portion 260. The microphone 231 is arranged in the circuit board space portion 250 and on the control circuit board 230. The partition 220 is provided with a microphone outlet hole 221.

[0065] The liquid cup housing 500 includes an exposed portion 540 and a connecting portion 550, wherein the connecting portion 550 is connected to one end of the exposed portion 540 and forms a step surface 560, wherein the connecting portion 550 is used to be arranged in the atomizer space portion 260, and the step surface 560 is used to abut against the component housing 210; thereby fixing the electronic atomizer 300 on the component housing 210.

[0066] The base 400 is connected to a side of the connecting portion 550 away from the exposed portion 540, the air outlet 530 is located on the exposed portion 540, and the first air inlet 510 is also arranged on the exposed portion 540; a first gap 570 is arranged between the side of the base 400 away from the connecting portion 550 and the partition 220, and a second gap 580 is arranged between the outer wall of the connecting portion 550 and the inner wall of the atomizer space portion 260; the electronic atomizer 300 also includes a second air inlet 520, which is arranged on the side wall of the connecting portion 550, and the microphone air outlet 221, the first gap 570, the second gap 580, the second air inlet 520, the electrode channel 750, the atomization channel 441 and the air outlet 530 are connected in sequence.

[0067] The second gap 580 includes a channel 581 opened on the outer wall of the connecting portion 550, so that the outer wall of the connecting portion 550 can be in contact with the inner wall of the component housing 210, thereby improving the stability of the connection.

[0068] When the user inhales from one side of the air outlet 530, the gas in the circuit board space 250 flows along the path of the microphone air outlet 221, the first gap 570, the second gap 580, the second air inlet 520, the electrode channel 750 and the atomization channel 441, resulting in low pressure near the microphone 231 of the battery assembly 20. When the microphone 231 detects negative pressure, it controls the control circuit board 230 to supply power to the atomization core 440 to generate aerosol, thereby ensuring the normal operation of the microphone 231.

[0069] Furthermore, the number of the electrode columns 700 includes at least two, namely a first electrode column 710 and a second electrode column 720, one end of the first electrode column 710 is located on the side of the base 400 away from the liquid cup shell 500, and the other end passes through the base 400 to be connected to the liquid cup shell 500, one end of the second electrode column 720 is located on the side of the base 400 away from the liquid cup shell 500, and the other end passes through the base 400 to be connected to the liquid cup shell 500, and the first electrode column 710 is electrically connected to the positive electrode of the atomizer core 440, and the second electrode column 720 is electrically connected to the negative electrode of the atomizer core 440; the electrode channel 750 is provided in both the first electrode column 710 and the second electrode column 720.

[0070] The number of the second air inlet holes 520 includes at least two, namely a third sub-air inlet hole 521 and a fourth sub-air inlet hole 522. The third sub-air inlet hole 521 and the fourth sub-air inlet hole 522 are both arranged on the side wall of the connecting part 550, and the third sub-air inlet hole 521 and the fourth sub-air inlet hole 522 are arranged opposite to each other.
