[0029] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. The described embodiments are only used to explain the idea of the present invention and should not be regarded as a limitation on the protection scope of the present application.

[0030] As Figure 1 shown, in some embodiments provided by the present application, the electronic atomization device 100 includes a power supply device 12, a controller 30, an input device 20, m heating elements 50, and m control switches 40. Among them, m is an integer greater than or equal to 2.

[0031] The power supply device 12 is electrically connected to the controller 30. The power supply device 12 is used to provide the electric energy required for the controller 30 to be in an operating state and the electric energy controlled by the controller 30. The power supply device 12 is also electrically connected to the input device 20. The power supply device 12 is used to provide the electric energy required for the input device 20 to be in an operating state.

[0032] The input device 20 is electrically connected to the controller 30. The input device 20 is used to provide a control signal matching the heating mode. Different heating modes result in different control signals provided by the input device 20. The input device 20 receives external control instructions in a wired communication or wireless communication manner. Different control instructions represent different heating modes. The input device 20 that receives a control instruction outputs a control signal matching the control instruction.

[0033] The controller 30 is electrically connected to m control switches 40 respectively, and the m control switches 40 are electrically connected to m heating elements 50 in one-to-one correspondence. The controller 30 is configured to output a conduction signal to p control switches 40 according to the pth control signal corresponding to the pth heating mode provided by the input device 20. The control switch 40 is configured to control the heating element 50 to heat according to the received conduction signal. The heating element 50 is configured to heat the aerosol generation matrix after being powered on. Wherein, p is an integer greater than or equal to 1 and less than or equal to m.

[0034] For example, if the input device 20 provides a first control signal, the controller 30 outputs a conduction signal to one control switch 40 (i.e., Figure 1 any one of the first control switch 40_1 to the mth control switch 40_m shown) according to the received first control signal, and the one control switch 40 that receives the conduction signal controls the heating element 50 electrically connected to itself to heat. For example, if the input device 20 provides a second control signal, the controller 30 outputs a conduction signal to two control switches 40 (i.e., Figure 1 any two of the first control switch 40_1 to the mth control switch 40_m shown) according to the received second control signal, and the two control switches 40 that receive the conduction signal control the heating elements 50 electrically connected to themselves to heat. And so on, if the input device 20 provides the mth control signal, the controller 30 outputs a conduction signal to all the control switches 40 according to the received mth control signal, so that all the heating elements 50 (i.e., m heating elements 50) are heated.

[0035] In the electronic atomization device 100 provided in this embodiment, by providing a controller 30 electrically connected to m control switches 40 respectively, m heating elements 50 electrically connected to the m control switches 40 in one-to-one correspondence, and an input device 20 electrically connected to the controller 30, the controller 30 can output a conduction signal to the control switches 40 in a number matching the control signal according to the control signal provided by the input device 20, and then the control switches 40 in the matching number control the heating elements 50 in the matching number to heat, so as to realize that the controller 30 controls different numbers of heating elements 50 to heat based on different control signals. Since the controller 30 can control different numbers of heating elements 50 to heat, the electronic atomization device 100 can provide different suction tastes generated based on different numbers of heating elements 50, enriching the user's suction experience.

[0036] Further, in some embodiments provided in the present application, the controller 30 includes a processing chip 32 and a circuit board 34. The processing chip 32 is electrically connected to the input device 20, the circuit board 34, and m control switches 40 respectively. As Figure 2As shown, an input pin IN_1 of the processing chip 32 is electrically connected to the input device 20, and m output pins (OUT_1 to OUT_m) of the processing chip 32 are electrically connected to m control switches 40.

[0037] Specifically, the control switch 40 is a switching transistor, and the control terminal of each switching transistor ( Figure 2 shown as 40_1 to 40_m) is electrically connected to one of the m output pins ( Figure 2 shown as OUT_1 to OUT_m), the input terminal of each switching transistor is electrically connected to the power supply terminal B+ of the power supply device 12, and the output terminal of each switching transistor is electrically connected to the anode in one heating element 50 ( Figure 2 shown as one of V+1 to V+m).

[0038] When the switching transistor receives the conduction signal transmitted by the output pin, the switching transistor is in the conduction state, so that the switching transistor outputs the electric energy provided by the power supply terminal to the heating element 50, and after the heating element 50 is powered on, it heats the aerosol generating matrix. It is worth mentioning that when the switching transistor does not receive the conduction signal, the switching transistor is in the off state, so that the heating element 50 does not work.

[0039] Exemplarily, the controller 30 outputs a conduction signal to the p-th switching transistor (a total of one switching transistor) according to the received first control signal, and the p-th switching transistor that receives the conduction signal is in the conduction state, so that one heating element 50 (a total of one heating element 50) electrically connected to the p-th switching transistor can be heated according to the electric energy provided by the power supply terminal B+.

[0040] Exemplarily, the controller 30 outputs a conduction signal to the k-th switching transistor and the k+1-th switching transistor (a total of two switching transistors) according to the received second control signal, and the k-th switching transistor and the k+1-th switching transistor that receive the conduction signal are in the conduction state, so that one heating element 50 electrically connected to the k-th switching transistor and one heating element 50 electrically connected to the k+1-th switching transistor (a total of two heating elements 50) can be heated according to the electric energy provided by the power supply terminal B+. In this example, k is an integer greater than or equal to 0 and less than or equal to m-1.

[0041] Exemplarily, the controller 30 outputs a conduction signal to the first switching transistor to the m-th switching transistor (a total of m switching transistors) according to the received m-th control signal, and the m switching transistors that receive the conduction signal are in the conduction state, so that all m heating elements 50 can be heated according to the electric energy provided by the power supply terminal B+.

[0042] Further, in some embodiments provided by the present application, for two consecutive heatings of the electronic atomization device 100, when the controller 30 outputs conduction signals to n control switches 40 according to the nth control signal of the input device 20 in the previous time, and outputs conduction signals to q control switches 40 according to the qth control signal of the input device 20 in the current time, the controller 30 is further configured to control at least one of the q control switches 40 to be different from the n control switches 40.

[0043] In this embodiment, n is an integer less than m and greater than or equal to 1, and q is an integer less than m and greater than or equal to 1.

[0044] It is worth mentioning that in this embodiment, the two consecutive heatings can be the same heating mode or different heating modes.

[0045] For example, assume that m is equal to 4, that is, the electronic atomization device 100 includes four heating elements 50 and four control switches 40. The input device 20 can provide four control signals (the first control signal to the fourth control signal) corresponding to four heating modes (the first heating mode to the fourth heating mode) respectively.

[0046] Exemplarily, in the previous heating, the input device 20 provides the second control signal corresponding to the second heating mode, and the controller 30 controls the first control switch 40 and the third control switch 40 among the four control switches 40 to conduct according to the second control signal. In the current heating, the output device provides the third control signal corresponding to the third heating mode, and the controller 30 controls the first control switch 40, the second control switch 40, and the fourth control switch 40 among the four control switches 40 to conduct according to the third control signal. Compared with the two control switches 40 that were conducted in the previous time, two of the three control switches 40 that are conducted in the current time are different.

[0047] In the previous heating, the first heating element 50 electrically connected to the first control switch 40 is heated, and the third heating element 50 electrically connected to the third control switch 40 is heated. In the current heating, the first heating element 50 electrically connected to the first control switch 40 is heated, the second heating element 50 electrically connected to the second control switch 40 is heated, and the fourth heating element 50 electrically connected to the fourth control switch 40 is heated.

[0048] In this way, compared with the two heating elements 50 that were heated in the previous time, two of the three heating elements 50 that are heated in the current time are different, so that the third heating element 50 that was heated in the previous time does not work in the current time, and further at least one of the two heating elements 50 that were heated in the previous time does not work in the current time.

[0049] It is worth mentioning that it is also possible that the first heating element 50 that was heated in the previous time does not work in the current time. That is, in the current heating, the controller 30 controls the second control switch 40, the third control switch 40, and the fourth control switch 40 among the four control switches 40 to conduct according to the third control signal. It is also possible to ensure that at least one of the two heating elements 50 that were heated in the previous time does not work in the current time, so as to ensure that at least one of the four heating elements 50 is not always in the working state in the previous and current heating, thereby extending the service life of the heating element.

[0050] Exemplarily, in the previous and current heating, the input device 20 provides the third control signal corresponding to the third heating mode. In the previous heating, the controller 30 controls the first control switch 40, the second control switch 40, and the third control switch 40 to conduct according to the third control signal. In the current heating, the controller 30 controls the second control switch 40, the third control switch 40, and the fourth control switch 40 to conduct according to the third control signal. Compared with the three control switches 40 that were conducted in the previous time, one of the three control switches 40 that are conducted in the current time is different.

[0051] Correspondingly, in the previous heating, the first heating element 50, the second heating element 50, and the third heating element 50 are heated. And in the current heating, the first heating element 50, the second heating element 50, and the fourth heating element 50 are heated.

[0052] In this way, compared with the three heating elements 50 that were heated in the previous time, one of the three heating elements 50 that are heated in the current time is different, so as to ensure that at least one of the three heating elements 50 that were heated in the previous time does not work in the current time, so as to ensure that at least one of the four heating elements 50 is not always in the working state in the previous and current heating, thereby extending the service life of the heating element 50.

[0053] Exemplarily, in the previous and current heating, the input device 20 provides the second control signal corresponding to the second heating mode. In the previous heating, the controller 30 controls the first control switch 40 and the second control switch 40 to conduct according to the second control signal, and then the first heating element 50 and the second heating element 50 are heated.

[0054] Then, in the subsequent heating, the controller 30 controls the second control switch 40 and the third control switch 40 to conduct according to the second control signal, so that the second heating element 50 and the third heating element 50 are heated; or, the controller 30 controls the second control switch 40 and the fourth control switch 40 to conduct according to the second control signal, so that the second heating element 50 and the fourth heating element 50 are heated; or, the controller 30 controls the first control switch 40 and the third control switch 40 to conduct according to the second control signal, so that the first heating element 50 and the third heating element 50 are heated; or, the controller 30 controls the first control switch 40 and the fourth control switch 40 to conduct according to the second control signal, so that the first heating element 50 and the fourth heating element 50 are heated; or, the controller 30 controls the third control switch 40 and the fourth control switch 40 to conduct according to the second control signal, so that the third heating element 50 and the fourth heating element 50 are heated.

[0055] Exemplarily, in the two heating processes before and after, the input device 20 provides the first control signal corresponding to the first heating mode in both cases. In the previous heating, the controller 30 controls the first control switch 40 to conduct according to the first control signal, so that the first heating element 50 is heated.

[0056] Then, in the subsequent heating, the controller 30 controls the second control switch 40 to conduct according to the first control signal, so that the second heating element 50 is heated; or, the controller 30 controls the third control switch 40 to conduct according to the first control signal, so that the third heating element 50 is heated; or, the controller 30 controls the fourth control switch 40 to conduct according to the first control signal, so that the fourth heating element 50 is heated.

[0057] Furthermore, in some embodiments provided in the present application, the electronic atomization device 100 is configured to form a first atomization channel and a second atomization channel. Among them, one of the first atomization channel and the second atomization channel is provided with i heating elements, and the other of the first atomization channel and the second atomization channel is provided with m - i heating elements.

[0058] Taking the electronic atomization device 100 including 4 heating elements as an example, please refer to Figure 3 and Figure 4 . In some embodiments provided in the present application, the electronic atomization device 100 is configured to form a first atomization channel 671 and a second atomization channel 672. It is worth mentioning that the first atomization channel 671 and the second atomization channel 672 can be independent of each other, that is, the first atomization channel 671 and the second atomization channel 672 are not connected to each other. The first atomization channel 671 and the second atomization channel 672 can also be connected. Among them, the first atomization channel 671 is provided with 2 heating elements 50 (that is, Figure 4 50_1 and 50_2 inFigure 4 50_3 and 50_4 therein).

[0059] The two heating elements 50 provided in the first atomization channel 671 are arranged along the axial direction of the first atomization channel 671, and the two heating elements 50 provided in the second atomization channel 672 are arranged along the axial direction of the second atomization channel 672. Among them, as Figure 5 shown, the two heating elements 50 provided in the first atomization channel 671 share the first pin 52 for common cathode setting, and the anodes are respectively set by the second pin 54 and the third pin 56. Similarly, the two heating elements 50 provided in the second atomization channel 672 are set with a common cathode, while the anodes are respectively set. In this way, combined with Figure 2 shown, the output end of a control switch 40 is electrically connected to the anode of a heating element 50. When this control switch 40 is turned on, the heating element 50 electrically connected to this control switch 40 forms a path and is heated.

[0060] In some other examples provided in the present application, it may also be that one of the first atomization channel 671 and the second atomization channel 672 is provided with 1 heating element 50, and the other of the first atomization channel 671 and the second atomization channel 672 is provided with 3 heating elements 50. The 3 heating elements 50 provided in the same atomization channel (the first atomization channel 671 or the second atomization channel 672) may also be set with a common cathode, while the anodes are respectively set.

[0061] Further, please continue to refer to Figure 4 and Figure 6 , in some embodiments provided in the present application, the electronic atomization device 100 further includes a liquid storage housing 62. The liquid storage housing 62 is configured to form a liquid storage cavity 621, and the liquid storage cavity 621 is used to accommodate the aerosol generating matrix. The liquid storage cavity 621 is communicated with the first atomization channel 671 and the liquid storage cavity is communicated with the second atomization channel 672. In this way, the aerosol generating matrix accommodated in the liquid storage housing 62 can flow through the first atomization channel 671 and the second atomization channel 672, and the aerosol generating matrix is heated by the heating element 50 provided in the first atomization channel 671 or the heating element 50 provided in the second atomization channel 672 to obtain aerosol.

[0062] Specifically, the liquid storage housing 62 includes an upper sealing portion 623, a lower sealing portion 622, and a hollow liquid storage main portion 621. The upper sealing portion 623 covers the first end of the liquid storage main portion 621, the lower sealing portion 622 covers the second end of the liquid storage main portion 621, the first end and the second end are oppositely arranged, and the upper sealing portion 623, the liquid storage main portion 621, and the lower sealing portion 622 jointly form the liquid storage cavity 621.

[0063] Further, please continue to refer to Figure 4, the electronic atomization device 100 further includes a liquid storage cotton 64. The liquid storage cotton 64 is filled in the liquid storage cavity 621, and the liquid storage cotton 64 is configured to form a first atomization channel 671 and a second atomization channel 672. In this way, in the electronic atomization device 100 provided in this embodiment, the liquid storage housing 62 integrates the liquid storage performance and the atomization performance.

[0064] Further, please continue to refer to Figure 4 , the electronic atomization device 100 further includes an atomization bracket 66 and a liquid guiding cotton 68. An atomization bracket 66 is disposed in the first atomization channel 671, a second atomization bracket 66 is disposed in the second atomization channel 672, the liquid guiding cotton 68 is filled between the heating element 50 and the atomization bracket 66, and the liquid guiding cotton 68 is connected to the liquid storage cotton 64. The liquid guiding cotton 68 is used to introduce the aerosol generating matrix on the liquid storage cotton 64 into the interior of the atomization bracket 66 for the heating element 50 to heat the aerosol generating matrix.

[0065] Further, please continue to refer to Figure 3 , Figure 4 and Figure 6 , the electronic atomization device 100 further includes a main housing 70. The main housing 70 is configured to form a receiving cavity 71. The power supply device 12, the liquid storage housing 62, the controller 30, m control switches 40, and m heating elements 50 are all disposed in the receiving cavity 71. The input device 20 is disposed on the main housing 70 and is for user operation. That is, in the electronic atomization device 100 provided in this embodiment, through the main housing 70, various components with liquid storage performance, atomization performance, and power storage performance are integrated into one.

[0066] Further, please continue to refer to Figure 3 , Figure 4 and Figure 6 , the input device 20 includes a trigger portion 22 and a sensing portion 24. The trigger portion 22 is disposed on the main housing 70, the sensing portion 24 is disposed on the circuit board 34, and the sensing portion 24 is electrically connected to the circuit board 34 and the processing chip 32 respectively. The trigger portion 22 is for user operation. When the trigger portion 22 is operated to squeeze the sensing portion 24, the sensing portion 24 converts the number of continuous squeezes into a control signal corresponding to the heating mode.

[0067] For example, if the user presses the trigger portion 22 once, the trigger portion 22 squeezes the sensing portion 24 once. The sensing portion 24 converts the single squeeze received into a first control signal corresponding to the first heating mode and outputs the first control signal to the second sub-circuit board 342. Subsequently, the subsequent processing chip 32 receives the first control signal and outputs a conduction signal to one of the m control switches 40. For example, if the user continuously presses the trigger portion 22 twice, the trigger portion 22 squeezes the sensing portion 24 twice. The sensing portion 24 converts the two squeezes received into a second control signal corresponding to the second heating mode and outputs the second control signal to the second sub-circuit board 342. Subsequently, the subsequent processing chip 32 receives the second control signal and outputs a conduction signal to two of the m control switches 40. By analogy, if the user continuously presses the trigger portion 22 p times, the trigger portion 22 squeezes the sensing portion 24 p times. The sensing portion 24 converts the p squeezes received into a p-th control signal corresponding to the p-th heating mode.

[0068] Further, please refer to Figure 4 and Figure 6 , the electronic atomization device 100 further includes a bracket 80 disposed in the accommodation cavity 71. The bracket 80 includes a first support portion 82 and a second support portion 84. The second support portion 84 is disposed on the bottom of the main housing 70. The second support portion 84 is connected to the first support portion 82 to support the first support portion 82. Along the axial direction of the main housing 70, the first support portion 82 is disposed between the power supply device 12 and the liquid storage housing 62, and the liquid storage housing 62 is located on the first support portion 82.

[0069] The circuit board 34 includes a first sub-circuit board 341 and a second sub-circuit board 342. The first sub-circuit board 341 is disposed on the first support portion 82. The second sub-circuit board 342 is electrically connected to the first sub-circuit board 341. The second sub-circuit board 342 is disposed on the bottom of the main housing 70, and the second sub-circuit board 342 is clamped between the power supply device 12 and the side wall of the main housing 70.

[0070] The sensing portion 24 of the input device 20 is disposed on the second sub-circuit board 342, so that the trigger 22 is correspondingly disposed on the side wall of the main housing 70, facilitating the user to hold the main housing 70 and perform a squeezing operation.

Moreover, the main housing 70 is provided with a charging through-hole corresponding to the charging interface 14, so that an external power supply line can pass through the charging through-hole and be electrically connected to the charging interface 14 to charge the power supply device 12.

[0073] Furthermore, as Figures 7 to 9 shown, the first support portion 82 and the second support portion 84 together form an air intake channel 83. The air intake channel 83 is respectively communicated with the first atomization channel 671 and the second atomization channel 672. The main housing 70 is further provided with an air intake through-hole 75 communicated with the air intake channel 83. In this way, the air outside the main housing 70 sequentially passes through the air intake through-hole 75 and the air intake channel 83, and then enters the first atomization channel 671 and / or the second atomization channel 672. The air entering the first atomization channel 671 and / or the second atomization channel 672 is mixed with the aerosol and then flows out of the main housing 70.

[0074] Exemplarily, the main housing 70 includes a mouthpiece portion 72 and a main body portion 74. The mouthpiece portion 72 is provided on the main body portion 74. The mouthpiece portion 72 and the main body portion 74 together form a receiving cavity 71. The mouthpiece portion 72 is further provided with an air outlet channel 73.

Furthermore, as Figure 6 shown, the main body portion 74 includes a receiving portion 741 and a supporting portion 742. The supporting portion 742 is connected to one end of the receiving portion 741, and the supporting portion 742 is detachably connected to the receiving portion 741, which is convenient for quickly assembling devices such as the liquid storage housing 62 into the main housing 70.

[0075] Furthermore, please refer to Figures 6 to 8 , the first support portion 82 extends towards the bottom of the main housing 70 to form a first limiting portion 821 and a second limiting portion 822. The first limiting portion 821 and the second limiting portion 822 are oppositely arranged, that is, the first limiting portion 821 and the second limiting portion 822 are arranged one in front and the other behind. The second sub-circuit board 342 is inserted between the first limiting portion 821 and the second limiting portion 822. The first limiting portion 821 and the second limiting portion 822 together limit the shaking of the second sub-circuit board 342 in the receiving cavity 71.

[0076] Furthermore, in some embodiments provided by the present application, as Figure 4 and Figure 6As shown, the electronic atomization device 100 further includes a display element 92. The display element 92 is disposed on the main housing 70. Specifically, the display element 92 is disposed on the outer side wall of the main housing 70. Compared with the top and bottom of the main housing 70, since the outer side wall of the main housing 70 has a larger surface area, the large-screen display element 92 can be disposed on the outer side wall of the main housing 70.

[0077] In this embodiment, the display element 92 is used to display the quantity information of the heating elements 50 associated with the heating mode. For example, when the controller 30 receives the third control signal provided by the input device 20, if there are three heating elements 50, the display element 92 displays a text symbol representing the quantity of three in its display area, such as "three", "3", "three", "three", etc. Further, the display element 92 can also be used to display the remaining power information of the power supply device 12, and / or the remaining information of the aerosol generating substrate in the liquid storage housing 62.

[0078] Further, in some embodiments provided in this application, Figure 3 , Figure 4 as well as Figure 6 As shown, the electronic atomization device 100 also includes a protective member 94. The protective member 94 is located on the side of the display member 92 away from the main housing 70, and the protective member 94 covers the display member 92 and is connected to the main housing 70. Based on the setting of the protective member 94, the display member 92 can be prevented from being exposed, and the display member 92 can be prevented from being scratched or damaged during use or under the action of external forces, and the display member 92 can be protected. In addition, the protective member 94 also has the function of filtering light of a certain wavelength, so that the user can clearly identify the information displayed on the display member 92 even in a strong sunlight environment.
