The housing is provided with a sliding cavity and an aerosol substrate accommodating cavity for accommodating the aerosol substrate; the sliding cavity is communicated with the aerosol substrate accommodating cavity. The heating module is provided with a heating cavity for heating the aerosol substrate, and the heating cavity is communicated with the sliding cavity. The ejecting module is arranged in the aerosol substrate accommodating cavity and is used to apply a force to the aerosol substrate in the aerosol substrate accommodating cavity to eject the aerosol substrate into the sliding cavity. The top-up module is slidably arranged in the sliding cavity to close or open the outlet of the aerosol substrate accommodating cavity and top up the aerosol substrate into the heating cavity. The aerosol substrate detection module is arranged at the position of the top-up module facing the aerosol substrate accommodating cavity when the top-up module closes the outlet of the aerosol substrate accommodating cavity; the aerosol substrate detection module is used to detect whether the aerosol substrate in the aerosol substrate accommodating cavity is sufficient.

[0006] Optionally, the aerosol substrate detection module is an elastic switch; the elastic switch detects whether the aerosol substrate in the aerosol generating device is sufficient by detecting the on-off of a detection circuit.

[0007] Optionally, the aerosol generating device includes a pressure sensor and an elastic member. The elastic member is disposed at the position where the upper top module faces the aerosol substrate accommodating cavity when the upper top module closes the outlet of the aerosol substrate accommodating cavity; and the elastic member is located on the pressure sensor.

[0008] Optionally, the upper top module includes an upper sliding rod, a first spring, and a top block; the upper sliding rod is fixed in the housing, the first spring is sleeved on the upper sliding rod, the top block is slidably sleeved on the upper sliding rod and is connected to the first spring; the top block slides on the upper sliding rod to close or open the outlet of the aerosol substrate accommodating cavity.

[0009] Optionally, the ejecting module includes a second spring and an ejecting block. The second spring is connected to the ejecting block, and the ejecting block is used to eject the aerosol substrate in the aerosol substrate accommodating cavity.

[0010] The present invention also discloses an aerosol substrate detection method, which is applied to the aerosol generating device as described above, and is characterized in that it includes the steps of:

[0011] Step A: Obtain an aerosol substrate detection signal;

[0012] Step B: According to the aerosol substrate detection signal, judge whether the aerosol substrate in the aerosol substrate accommodating cavity is sufficient and the usage quantity of the aerosol substrate; if there is no aerosol substrate, give a prompt of no aerosol substrate; if there is aerosol substrate, give a prompt of having aerosol substrate and the usage quantity of the aerosol substrate.

Detailed Embodiment

[0038] It should be understood that the terms, the specific structures and functional details disclosed herein are only for the purpose of describing specific embodiments, which are representative, but the present invention can be specifically implemented in many alternative forms and should not be construed as being limited only to the embodiments set forth herein.

[0039] The present invention will be described in detail below with reference to the accompanying drawings and optional embodiments.

[0040] As Figures 1 to 3As shown, as an embodiment of the present invention, an aerosol generating device 10 is disclosed. The aerosol generating device 10 includes a housing 100, a heating module 200, an ejecting module 300, an upward pushing module 400, and an aerosol substrate detection module 500. The housing 100 is provided with a sliding cavity 110 and an aerosol substrate accommodating cavity 120 for accommodating an aerosol substrate 20; the sliding cavity 110 communicates with the aerosol substrate accommodating cavity 120. The heating module 200 is provided with a heating cavity 210 for heating the aerosol substrate 20, and the heating cavity 210 communicates with the sliding cavity 110. The ejecting module 300 is disposed in the aerosol substrate accommodating cavity 120 and is configured to apply a force to the aerosol substrate 20 in the aerosol substrate accommodating cavity 120 to eject the aerosol substrate 20 into the sliding cavity 110. The upward pushing module 400 is slidably disposed in the sliding cavity 110 to close or open an outlet of the aerosol substrate accommodating cavity 120 and push the aerosol substrate 20 upward into the heating cavity 210. The aerosol substrate detection module 500 is disposed at a position of the upward pushing module 400 facing the aerosol substrate accommodating cavity 120 when the upward pushing module 400 closes the outlet of the aerosol substrate accommodating cavity 120; the aerosol substrate detection module 500 is configured to detect whether the aerosol substrate 20 in the aerosol substrate accommodating cavity 120 is sufficient.

[0041] The aerosol generating device 10 of the present invention stores the aerosol substrate 20 in the aerosol substrate accommodating cavity 120. When the upper pushing module 400 opens the outlet of the aerosol substrate accommodating cavity 120, the ejecting module 300 ejects the aerosol substrate 20 into the sliding cavity 110. Then, the upper pushing module 400 pushes the aerosol substrate 20 upward into the heating cavity 210 for heating to generate aerosol. In this way, the aerosol generating device 10 can store a large amount of aerosol substrate 20, and at the same time, outputting the aerosol substrate 20 is very simple and convenient. Correspondingly, an aerosol substrate detection module 500 is provided at the upper pushing module 400 corresponding to the outlet of the aerosol substrate accommodating cavity 120. By detecting whether the aerosol substrate 20 at the outlet of the aerosol substrate accommodating cavity 120 is sufficient, the aerosol substrate 20 is directly detected by the aerosol substrate detection module 500, so as to know whether the aerosol generating device 10 has enough aerosol substrate 20, with accurate results and little interference. Specifically, the aerosol substrate detection module 500 can be a pressure sensor 510 and / or a distance sensor 520, or can also be an elastic switch. More specifically, the distance sensor 520 can be an infrared sensor, an ultrasonic distance sensor, etc. Therefore, the aerosol substrate detection module 500 of the present invention directly judges whether the aerosol substrate is sufficient based on the detection parameters of itself, and directly detects the aerosol substrate. At present, for the scheme of judging whether the aerosol substrate is sufficient by temperature, the temperature is easily affected by factors such as the combustion condition of the aerosol substrate, the specific material of the aerosol substrate, the user's suction speed, and the heat dissipation condition of the aerosol generating device 10 itself, resulting in inaccurate results and large interference. The aerosol substrate 20 can be a cartridge, etc.

[0042] Regarding the installation position of the aerosol substrate detection module 500, in other embodiments, the aerosol substrate detection module 500 can also be installed on the housing 100 or the sliding cavity 110 and correspond to the outlet of the aerosol substrate accommodating cavity 120. At this time, the aerosol substrate detection module 500 is a non-contact sensor, such as an infrared sensor, an ultrasonic distance sensor, etc. And, the upper pushing module can be provided with a through hole corresponding to the aerosol substrate detection module 500, and the detection signal of the aerosol substrate detection module 500 reaches the outlet of the aerosol substrate accommodating cavity 120 through the through hole and detects the cartridge.

[0043] Specifically, as Figures 4 to 9 shown, the aerosol substrate detection module 500 is a pressure sensor 510 and / or a distance sensor 520, and the pressure sensor 510 and / or the distance sensor 520 are used to detect whether the aerosol substrate 20 in the aerosol substrate accommodating cavity 120 is sufficient and the usage quantity of the aerosol substrate 20. As Figure 1 、 Figure 4 and Figure 5As shown, when the detection module uses the pressure sensor 510 and the aerosol substrate 20 is sufficient, the aerosol substrate 20 at the outlet of the aerosol substrate accommodating cavity 120 presses on the pressure sensor 510. At this time, it is possible to determine whether there is sufficient aerosol substrate 20 based on the magnitude of the pressure detected by the pressure sensor 510. For example, Figure 3 and Figure 6 as shown, when the aerosol substrate 20 is insufficient, the aerosol substrate 20 does not press on the pressure sensor 510. At this time, it is possible to determine that there is no sufficient aerosol substrate 20 based on the magnitude of the pressure detected by the pressure sensor 510. Similarly, Figures 7 to 9 as shown, when the detection module uses the distance sensor 520 and the aerosol substrate 20 is sufficient, the distance from the aerosol substrate 20 at the outlet of the aerosol substrate accommodating cavity 120 to the distance sensor 520 is small, and this distance is detected by the distance sensor 520, based on which it is determined that there is sufficient aerosol substrate 20; when the aerosol substrate 20 is insufficient, the distance from the aerosol substrate 20 at the outlet of the aerosol substrate accommodating cavity 120 to the distance sensor 520 is large, and this distance is detected by the distance sensor 520, based on which it is determined that there is no sufficient aerosol substrate 20.

[0044] Furthermore, when the aerosol substrate detection module 500 is the pressure sensor 510, after the aerosol substrate 20 is pushed out from the aerosol substrate accommodating cavity 120 and pushed up into the heating cavity 210, the subsequent aerosol substrate 20 in the aerosol substrate accommodating cavity 120 will be pushed again to press on the pressure sensor 510. During this entire process, the value detected by either the pressure sensor 510 or the distance sensor 520 will change once. For example, before the current aerosol substrate 20 is pushed out from the aerosol substrate accommodating cavity 120, the pressure value is a. During the pushing process, the pushing module 400 is pushed downward, and the pressure sensor 510 moves downward synchronously, thus disengaging from contact with the aerosol substrate 20. Since the current aerosol substrate 20 does not contact and press on the pressure sensor 510, and during the downward movement, when the pressure sensor disengages from contact with the aerosol substrate 20, the pressure sensor also does not contact the inner wall of the sliding cavity, and the pressure tends to be zero. After the current aerosol substrate 20 is completely pushed out, the new aerosol substrate 20 in the aerosol substrate accommodating cavity 120 presses on the pressure sensor 510 again, and the detected pressure value returns to a or is slightly less than a. This number of pressure changes of the pressure sensor 510 can reflect the number of times the aerosol substrate 20 has been used, thus achieving the purpose of the pressure sensor 510 detecting the usage quantity of the aerosol substrate 20. Based on the total storage quantity of the aerosol substrate 20 and the usage quantity of the aerosol substrate 20, the current remaining quantity of the aerosol substrate 20 can be obtained for the user's reference or to remind the user.

[0045] When the aerosol substrate detection module 500 is the distance sensor 520, the distance sensor will continuously detect distance values. When the distance sensor 520 is set on the upper top module, its changing trend changes according to the distance changes between the distance sensor 520 and the cartridge, and the inner wall of the sliding cavity during the up and down movement of the distance sensor 520. However, during multiple uses of the aerosol substrate 20, the distance values during each use are periodically and repeatedly changed. For example, taking Figures 1 to 3 the outlet structure of the sliding cavity and the aerosol substrate accommodation cavity in 1 as an example, the distance value between the distance sensor 520 and the aerosol substrate 20 remains unchanged first, being the value b 2 ; after the upper top module 400 slides, the distance value increases to b 1 , and at this time it is the distance between the distance sensor 520 and the inner wall of the sliding cavity 110; after the upper top module 400 returns to its original position, the distance value becomes b again 1 →b 2 →b 1 again, and at this time it is the distance between the distance sensor 520 and the aerosol substrate 20. During this process, the distance value undergoes a periodic change of b

[0046] →b

[0047] . After each such periodic change, it indicates that the number of aerosol substrates decreases by one. By this, the usage quantity of the aerosol substrate 20 can be obtained. Furthermore, based on the total storage quantity of the aerosol substrate 20 and the usage quantity of the aerosol substrate 20, the current remaining quantity of the aerosol substrate 20 can be obtained for the user's reference or to remind the user.

[0046] In another embodiment, when the distance sensor 520 is fixed on the sliding cavity, the periodic change of the distance value is a process of large → small → large. At first, the large value is that the detection signal of the distance sensor 520 passes through the upper top module 400 to detect the aerosol substrate 20; after the upper top module 400 slides, the aerosol substrate 20 is pushed into the sliding cavity, the distance between the aerosol substrate 20 and the distance sensor 520 becomes smaller, and the detected value of the distance sensor 520 becomes smaller; after the upper top module 400 returns to its original position, the detection signal of the distance sensor 520 passes through the upper top module 400 again to detect the aerosol substrate 20, and the value becomes larger again. In this embodiment, the upper top module is correspondingly provided with through holes to facilitate the detection signal to pass through the upper top module.

[0047] When the aerosol substrate detection module 500 simultaneously uses the pressure sensor 510 and the distance sensor 520, based on the pressure value and the distance value, it is possible to determine the cartridge jamming and the specific cartridge jamming position in the aerosol substrate accommodating cavity 120. For example, when the number of times the value detected by the pressure sensor 510 or the distance sensor 520 changes indicates that there is still remaining aerosol substrate 20, if the current pressure value detected by the pressure sensor 510 is too small or tends to zero at this time, it indicates that there is a cartridge jamming situation. At the same time, by combining the current distance value detected by the distance sensor 520, the specific cartridge jamming position can be known. For example, it may be that the cartridge jams at the outlet of the aerosol substrate accommodating cavity 120, or it may be that the cartridge jams in the aerosol substrate accommodating cavity 120.

[0048] In a more specific embodiment of the pressure sensor 510, such as Figure 4 and Figure 5 shown, the aerosol generating device 10 further includes an elastic member 530. The elastic member 530 is disposed at the position where the upper pushing module 400 faces the aerosol substrate accommodating cavity 120 when the upper pushing module 400 closes the outlet of the aerosol substrate accommodating cavity 120; and the elastic member 530 is located on the pressure sensor 510. In this solution, by further providing the elastic member 530 on the pressure sensor 510, the compressive force from the aerosol substrate 20 can be better received. In this case, the acting force of the upper pushing module 400 does not need to be configured too large. When the acting force of the upper pushing module 400 is configured too large, problems such as the aerosol substrate 20 in the aerosol substrate accommodating cavity 120 being damaged due to excessive force, the aerosol substrate 20 being pushed out of the aerosol substrate accommodating cavity 120 too fast, and it being easy to push out more than one aerosol substrate 20 at a time may occur. Specifically, the elastic member 530 can be a spring, a spring sheet, or a combination of a spring and a push pin.

[0049] In the above specific embodiments where the aerosol substrate detection module 500 is a sensor, in addition to using the pressure sensor 510 and the distance sensor 520, it can also be other types of sensors. In another embodiment, the aerosol substrate detection module 500 is an elastic switch (not shown); the elastic switch is connected to the detection circuit, and the elastic switch detects whether the aerosol substrate 20 in the aerosol generating device 10 is sufficient through the detection circuit. In this solution, when the aerosol substrate 20 is sufficient, the aerosol substrate 20 at the outlet of the aerosol substrate accommodating cavity 120 presses the elastic switch, and the elastic switch closes, and the detection circuit is in a conductive state, so it can be determined that the aerosol substrate 20 in the current aerosol substrate accommodating cavity 120 is sufficient; when the aerosol substrate 20 is insufficient, the aerosol substrate 20 at the outlet of the aerosol substrate accommodating cavity 120 does not press the elastic switch, the elastic switch disconnects, and the detection circuit is open, so it can be determined that the aerosol substrate 20 in the current aerosol substrate accommodating cavity 120 is insufficient.

[0050] It should be noted that the insufficient aerosol substrate 20 referred to in the present invention includes the situation where the aerosol substrate 20 is about to be exhausted and there is not much left, and also includes the situation where the aerosol substrate 20 is completely used up. When the aerosol substrate 20 is about to be exhausted and there is not much left, the aerosol substrate 20 only exists near the outlet of the accommodation cavity, and it is difficult for the ejection module 300 to apply a thrust to the remaining aerosol substrate 20 and it is difficult to apply pressure to the elastic switch and the pressure sensor 510.

[0051] More specifically, for the situation where the aerosol substrate 20 is about to be exhausted, there is not much left, and it only exists near the outlet of the accommodation cavity, a false aerosol substrate, such as a false cartridge, can be placed in the aerosol substrate accommodation cavity, so that all the aerosol substrates can be pushed out for use. When the false aerosol substrate is placed, the real aerosol substrate 20 and the false aerosol substrate can be distinguished by means of quantity or size, etc. For example, after the quantity of the real aerosol substrate 20 is used up, the remaining ones are false aerosol substrates. It is also possible to set the real aerosol substrate 20 and the false aerosol substrate to have different sizes, and judge the real aerosol substrate 20 and the false aerosol substrate according to the size.

[0052] Specifically, as Figures 1 to 3 shown, the upper ejection module 400 includes an upper sliding rod 410, a first spring 420 and a top block 430; the upper sliding rod 410 is fixed in the housing 100, the first spring 420 is sleeved on the upper sliding rod 410, the top block 430 is slidably sleeved on the upper sliding rod 410 and is connected to the first spring 420; the top block 430 slides on the upper sliding rod 410 to close or open the outlet of the aerosol substrate accommodation cavity 120. In this solution, the top block 430 slides on the upper sliding rod 410, the top block 430 avoids the outlet of the aerosol substrate accommodation cavity 120, the ejection module 300 ejects the aerosol substrate 20, and the top block 430 ejects the aerosol substrate 20 upward into the heating cavity 210 for heating. The first spring 420 plays an elastic pushing and supporting role on the top block 430, so that the top block 430 stays at the outlet of the aerosol substrate accommodation cavity 120 when the aerosol substrate 20 does not need to be ejected, ensuring that the aerosol substrate accommodation cavity 120 is closed. The sliding of the top block 430 can be electrically controlled or manually operated.

[0053] More specifically, the top block 430 is provided with a clamping portion 431 for clamping with the housing 100. The clamping portion 431 clamps with the housing 100 to limit the excessive movement of the top block 430. In addition, the aerosol generating device 10 further includes a battery 700, a circuit board 800, a power switch 900, etc., which will not be elaborated here one by one.

[0054] The ejection module 300 includes a second spring 310 and an ejection block 320. The second spring 310 is connected to the ejection block 320, and the ejection block 320 is used to eject the aerosol substrate 20 in the aerosol substrate accommodation cavity 120. In this solution, the second spring 310 supports and pushes the ejection block 320, and the ejection block 320 ejects the aerosol substrate 20 into the sliding cavity 110. Specifically, one end of the ejection block 320 away from the second spring 310 is an inclined surface 321, which can apply force to the aerosol substrate 20 better, and the ejection effect of the aerosol substrate 20 is better.

[0055] The aerosol generating device 10 includes a prompting module 600 provided on the housing 100. The prompting module 600 is used to prompt the storage condition of the aerosol substrate 20 in the aerosol substrate accommodation cavity 120. The prompting module 600 can be an indicator light. For example, when the aerosol substrate 20 is sufficient, the indicator light shows green; when there is little aerosol substrate 20 left, the indicator light shows orange; when the aerosol substrate 20 is completely consumed, the indicator light shows red. The prompting module 600 can also be a display screen, which displays specific information about the quantity of the aerosol substrate 20, etc. The prompting module 600 can also be a vibrator. For example, when the aerosol substrate 20 is sufficient, the vibrator does not start; when there is little aerosol substrate 20 left, the vibrator intermittently vibrates multiple times briefly; when the aerosol substrate 20 is completely consumed, the vibrator vibrates continuously for a long time. The prompting module 600 can also be a speaker or a buzzer.

[0056] Specifically, the shape of the heating cavity 210 is adapted to the shape of the aerosol substrate 20, and the heating effect of the aerosol substrate 20 is better.

[0057] As Figure 10 shown, as another embodiment of the present invention, an aerosol substrate detection method is disclosed, which is applied to the aerosol generating device 10 as described above, and includes the steps:

[0058] Step A: Obtain an aerosol substrate detection signal;

[0059] Step B: According to the aerosol substrate detection signal, judge whether the aerosol substrate in the aerosol substrate accommodation cavity is sufficient and the usage quantity of the aerosol substrate; if there is no aerosol substrate, issue a prompt of no aerosol substrate; if there is aerosol substrate, issue a prompt of having aerosol substrate and the usage quantity of the aerosol substrate.

[0060] The detection method of this embodiment directly detects the aerosol substrate 20 to obtain the aerosol substrate 20 detection signal, so as to know whether the aerosol generating device 10 has enough aerosol substrate 20 and the quantity of the aerosol substrate 20, and can accurately and specifically master the current storage condition of the aerosol substrate 20.

[0061] Specifically, step A is specifically as follows: a pressure sensor or a distance sensor obtains an aerosol substrate detection signal; step B specifically includes: judging the usage quantity of the aerosol substrate according to the change times of the aerosol substrate detection signal.

[0062] In this solution, every time the aerosol substrate 20 is pushed out from the aerosol substrate accommodating cavity 120, the value of the pressure sensor 510 or the distance sensor 520 changes once, which can reflect the usage times of the aerosol substrate 20, so as to achieve the purpose of detecting the usage quantity of the aerosol substrate 20 by the pressure sensor 510 or the distance sensor 520. According to the total storage quantity of the aerosol substrate 20 and the usage quantity of the aerosol substrate 20, the current remaining quantity of the aerosol substrate 20 can be obtained for the user to refer to or to remind the user.

[0063] In an embodiment, step A is specifically as follows: a pressure sensor or a distance sensor obtains an aerosol substrate detection signal; step B specifically includes: judging whether the aerosol substrate in the aerosol substrate accommodating cavity is sufficient according to the pressure value detected by the pressure sensor or the distance value detected by the distance sensor.

[0064] In this solution, when the pressure sensor 510 is adopted, when the aerosol substrate 20 is sufficient, the aerosol substrate 20 at the outlet of the aerosol substrate accommodating cavity 120 presses on the pressure sensor 510. At this time, it can be judged whether there is sufficient aerosol substrate 20 according to the magnitude of the pressure detected by the pressure sensor 510; when the aerosol substrate 20 is not sufficient, the aerosol substrate 20 does not press on the pressure sensor 510. At this time, it can be judged that there is no sufficient aerosol substrate 20 according to the magnitude of the pressure detected by the pressure sensor 510. Similarly, when the detection module adopts the distance sensor 520, when the aerosol substrate 20 is sufficient, the distance from the aerosol substrate 20 at the outlet of the aerosol substrate accommodating cavity 120 to the distance sensor 520 is small and is detected by the distance sensor 520, and it is judged that there is sufficient aerosol substrate 20 accordingly; when the aerosol substrate 20 is not sufficient, the distance from the aerosol substrate 20 at the outlet of the aerosol substrate accommodating cavity 120 to the distance sensor 520 is large and is detected by the distance sensor 520, and it is judged that there is no sufficient aerosol substrate 20 accordingly.

[0065] In an embodiment, step A is specifically as follows: a pressure sensor and a distance sensor obtain an aerosol substrate detection signal; the aerosol substrate detection method includes the steps of: judging whether the aerosol substrate in the aerosol substrate accommodating cavity is stuck according to the pressure value detected by the pressure sensor, and judging the stuck position according to the distance value detected by the distance sensor.

[0066] In this solution, a pressure sensor 510 and a distance sensor 520 are simultaneously used to obtain the detection signals of the aerosol substrate 20. Based on the pressure value and the distance value, it is possible to determine whether there is a cartridge jam in the aerosol substrate accommodating cavity 120 and the specific position of the cartridge jam. For example, when it is known through the number of times the values detected by the pressure sensor 510 or the distance sensor 520 change that there is still remaining aerosol substrate 20, if the current pressure value detected by the pressure sensor 510 is too small or tends to zero at this time, it indicates that there is a cartridge jam. At the same time, by combining the current distance value detected by the distance sensor 520, the specific position of the cartridge jam can be known. For example, it may be a cartridge jam at the outlet of the aerosol substrate accommodating cavity 120, or it may be a cartridge jam in the aerosol substrate accommodating cavity 120.
