Description

Technical Field

[0001] This application relates to the field of atomization technology, and more particularly to an aerosol generating device. Background Technology

[0002] Aerosol generating devices typically include an atomizer and a power supply component electrically connected to the atomizer. The atomizer, driven by the power supply component, atomizes the aerosol generating matrix to form an aerosol for user use.

[0003] In related technologies, the aerosol generator has a fixed output power. When the user inhales with a small inhale, the output power of the aerosol generator is too high, resulting in a higher aerosol temperature. Conversely, when inhaling with a large inhale, the output power of the aerosol generator is insufficient, resulting in less aerosol generation and a less satisfying inhalation experience. In other words, the inhalation experience of the aerosol generator in these technologies has significant room for improvement. Summary of the Invention

[0004] In view of this, the embodiments of this application aim to provide an aerosol generating device that is designed to improve the user's inhalation experience.

[0005] To solve the above problems, the technical solution of this application embodiment is implemented as follows:

[0006] Atomizing base, enclosed to form an atomizing channel;

[0007] The heating element is located at least partially in the atomization channel. The heating element includes multiple heating parts and multiple pins. One of the pins is connected to one end of all the heating parts, and the remaining pins are connected to the other end of each heating part. The output power of the aerosol generating device is switched by switching the electrical connection state of each heating part. The output power ranges from 5W to 150W.

[0008] In some embodiments, the resistance value of any one of the heating elements is different from the resistance values ​​of the other heating elements; or,

[0009] At least two of the heating elements have the same resistance.

[0010] In some embodiments, at least a portion of the heating element and the battery cell of the aerosol generating device form a parallel circuit; and / or,

[0011] At least a portion of the heating element and the battery cell of the aerosol generating device form a series circuit.

[0012] In some embodiments, each of the heating elements extends circumferentially along the atomizing channel; or,

[0013] The projection of each heating element along the axial direction of the atomizing channel onto a plane perpendicular to the axial direction of the atomizing channel forms a semi-enclosed structure.

[0014] In some embodiments, the aerosol generating device further includes a housing assembly and an air inlet valve, the atomizing component is disposed inside the housing assembly, the housing assembly has a main air inlet and at least one auxiliary air inlet, and the air inlet valve is disposed in the auxiliary air inlet.

[0015] In some embodiments, the cross-sectional area of ​​the auxiliary air inlet is different from that of the main air inlet.

[0016] In some embodiments, the intake valve includes a resilient valve flap, the resilient valve flap includes a connector and a plurality of elastic bodies, the connector is annular and seals against the wall of the auxiliary intake port, the elastic bodies are arranged circumferentially along the connector, one end of any elastic body is disposed on the inner wall of the connector, and the other end extends radially inward along the connector and forms a free end.

[0017] In some embodiments, a gap exists between two adjacent elastomers along the circumferential direction of the auxiliary air inlet; and / or,

[0018] The auxiliary air intake includes a first sub-hole and a second sub-hole that are axially connected. The two ends of the first sub-hole are respectively connected to the atmosphere and the second sub-hole. The diameter of the first sub-hole is larger than the diameter of the second sub-hole and a stepped surface is formed at the connection between the two. The connector is disposed in the first sub-hole and is sealed and fitted to the stepped surface.

[0019] In some embodiments, the auxiliary air intake has an inlet, through which the auxiliary air intake communicates with the atmosphere; wherein, along the radially inward direction of the connector, the surface of the elastomer closest to the atmosphere gradually moves away from the surface where the inlet is located.

[0020] In some embodiments, the at least one auxiliary air intake port includes a first auxiliary air intake port and a second auxiliary air intake port, the elastic valve flap disposed in the first auxiliary air intake port is a first elastic valve flap, and the elastic valve flap disposed in the second auxiliary air intake port is a second elastic valve flap.

[0021] Wherein, the cross-sectional area of ​​the flow channel of the first auxiliary air inlet is different from that of the second auxiliary air inlet; and / or, the thickness of the first elastic valve disc is different from that of the second elastic valve disc.

[0022] The aerosol generating device of this application embodiment includes a heating element comprising multiple heating sections and multiple pins. One pin is connected to all heating sections, and the remaining pins are connected to each heating section in a corresponding manner. The connection of the heating sections via one pin forms a unified whole, which facilitates the stable and reliable placement of each heating section within the atomization channel. Furthermore, by switching the electrical connection state of each heating section, at least some heating sections form a parallel circuit with the battery cell of the aerosol generating device; and / or, at least some heating sections form a series circuit with the battery cell of the aerosol generating device. This allows the overall resistance of the heating element to be changed, thereby switching the output power of the aerosol generating device and enabling it to output different power levels. Thus, the aerosol generating device can provide different output power according to different suction methods, which is beneficial for generating sufficient aerosol and controlling the aerosol at a suitable temperature, thereby improving the user's suction experience.

[0023] Furthermore, the aerosol generating device of this application embodiment can provide different output powers, thereby adapting to users using different suction methods. This helps to reduce the specifications of aerosol generating devices on the market, reduce the difficulty of selection for users, and thus improve the user's purchasing experience.

[0041] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0042] This application provides an aerosol generating device.

[0043] It should be noted that the specific type of aerosol generating device in the embodiments of this application is not limited. For example, the aerosol generating device can be a medical nebulizer, an air humidifier, or a nebulizer such as an electronic cigarette.

[0044] The aerosol generating device includes a power supply component and an atomizer.

[0045] The power supply unit is mainly used to supply power to the atomizer and control the opening and closing of the entire aerosol generation device. The atomizer is mainly used to contain the aerosol generation matrix and heat and atomize the aerosol generation matrix after being powered on. The aerosol generation matrix includes, but is not limited to, materials used for medical, wellness, health, and beauty purposes.

[0046] In some embodiments, the atomizer and power supply assembly can be mechanically and electrically connected together axially. Further, the atomizer and power supply assembly can be connected together in a detachable manner using magnetic connections, threaded connections, snap-fit ​​connections, or other similar methods. Both the atomizer and power supply assembly can be replaced or upgraded individually, reducing replacement costs and saving user expenses. Of course, in other embodiments, the atomizer and power supply assembly can also be connected together in a non-detachable manner.

[0047] Furthermore, the atomizer and / or power supply assembly are not limited to being cylindrical; they can also be other shapes such as elliptical or square columns.

[0048] Please see Figures 1 to 3 The aerosol generating device includes a housing assembly 20. Specifically, the housing assembly 20 includes a first sub-shell 21 and a second sub-shell 22. The first sub-shell 21 is the frame structure of the atomizer, and the second sub-shell 22 is the frame structure of the power supply assembly.

[0049] The aerosol generating device also includes an atomizing component 10, which is disposed inside the housing component 20. For details, please refer to... Figure 3 The atomizing component 10 is located inside the first sub-shell 21.

[0050] There are no restrictions on the type of atomizer.

[0051] For example, the atomizer can be a replaceable cartridge structure. That is, the atomizer includes an auxiliary e-liquid tank, which is detachably disposed as a whole within the first sub-shell 21. The auxiliary e-liquid tank is used to store at least a portion of the aerosol generating substrate. After the aerosol generating substrate in the auxiliary e-liquid tank is used up, a new auxiliary e-liquid tank can be replaced. Here, when replacing the auxiliary e-liquid tank, the atomizing component 10 does not need to be replaced, thus reducing the user's operating costs.

[0052] For example, please refer to Figure 3 Alternatively, the atomizer can be installed without an additional e-liquid tank; that is, once the atomizer's aerosol-generating matrix is ​​used up, a new atomizer can be installed. Here, when replacing the atomizer, the atomization assembly 10 is also replaced.

[0053] The power supply assembly also includes a battery cell, which is located inside the second sub-shell 22 and electrically connected to the atomizing assembly 10.

[0054] Please see Figure 3 The atomizing assembly 10 includes an atomizing base 11 and a heating element 12. The atomizing base 11 is provided with an atomizing channel 11a, and at least a portion of the heating element 12 is located in the atomizing channel 11a. That is, the heating element 12 may be completely located within the atomizing channel 11a; or, a portion of the heating element 12 may be located within the atomizing channel 11a, and another portion may be located outside the atomizing channel 11a.

[0055] The aerosol generating matrix can enter the atomization channel 11a. The heating element 12 is electrically connected to the battery cell and can generate heat under the electric drive of the battery cell. The aerosol generating matrix in the atomization channel 11a is heated and atomized to generate aerosol.

[0056] Please see Figure 3 and Figure 5 The heating element 12 includes multiple heating sections 121 and multiple pins 122. The heating section 121 is the component in the heating element 12 used to generate heat, and the two ends of the pins 122 are electrically connected to the battery cell and the heating section 121, respectively.

[0057] It should be noted that there are no restrictions on the specific type of pin 122. For example, pin 122 can be an electrode, contact, or other electrical connection structure.

[0058] It should be noted that, in the embodiments of this application, "multiple heating elements 121" refers to two or more arbitrary numbers of heating elements 121, and "multiple pins 122" refers to three or more arbitrary numbers of pins 122. It is understood that the number of pins 122 is related to the number of heating elements 121.

[0059] Please see Figure 5 One of the pins 122 is connected to all the heating elements 121, and the other pins 122 are connected to each heating element 121 in a corresponding manner.

[0060] For example, please refer to Figure 5 The plurality of heating elements 121 include a first heating element 1211, a second heating element 1212 and a third heating element 1213, and the plurality of pins 122 include a first pin 1221, a second pin 1222, a third pin 1223 and a fourth pin 1224. One end of the first pin 1221 is connected to the first heating element 1211, one end of the second pin 1222 is connected to the second heating element 1212, one end of the third pin 1223 is connected to the third heating element 1213, and one end of the fourth pin 1224 is connected to each heating element 121.

[0061] Here, the heating elements 121 are interconnected through the fourth pin 1224, so that the heating element 12 can be formed as an integral structure, which helps to improve the stability of the heating elements 121 in the atomization channel 11a.

[0062] In some embodiments, at least a portion of the heating element 121 forms a parallel circuit with the battery cell of the aerosol generating device. Here, all heating elements 121 may be connected in parallel, or only a portion of the heating elements 121 may be connected in parallel.

[0063] For example, please see Figure 5The fourth pin 1224 is electrically connected to the positive terminal of the battery cell, and the first pin 1221 and the second pin 1222 are electrically connected to the negative terminal of the battery cell, respectively. Thus, the first heating element 1211 and the second heating element 1212 are connected in parallel to the battery cell, and the electrical circuit of the third heating element 1213 is in a cut-off state.

[0064] It should be noted that the specific structure of each heating element 121 is not limited, and the structures of each heating element 121 can be different or the same. For example, some heating elements 121 can be composed of multiple heating elements connected in series, while some heating elements 121 can be composed of only one heating element.

[0065] In some embodiments, at least a portion of the heating element 121 forms a series circuit with the battery cell of the aerosol generating device.

[0066] For example, please see Figure 5 The first pin 1211 is electrically connected to the positive terminal of the battery cell, and the second pin 1222 is electrically connected to the negative terminal of the battery cell. Thus, the first heating element 1211 and the second heating element 1212 are connected in series with the battery cell, and the electrical circuit of the third heating element 1213 is in an off state. By connecting multiple heating elements 121 in series, the overall resistance of the heating element 12 can be increased, thereby reducing the output power of the aerosol generating device.

[0067] In some embodiments, some of the heating elements 121 are connected in parallel to form a parallel whole, which is then connected in series with another part of the heating elements 121.

[0068] It is understandable that the atomizing channel 11a has relatively ample space in its axial direction, and each heating element 121 can be arranged at intervals along the axial direction of the atomizing channel 11a. This facilitates the arrangement of each heating element 121 within the atomizing channel 11a, and the interval arrangement also allows each heating element 121 to be electrically isolated from each other.

[0069] The heating element 12 adopts a structure with multiple heating elements 121. By switching the electrical connection state of each heating element 121, the output power of the aerosol generating device can be switched. That is, the output power of the aerosol generating device can be adjusted without adjusting the output voltage of the battery cell. The operation of turning on or off the electrical circuit of the heating element 121 is relatively simple and easy to control. Therefore, it helps to reduce the difficulty of adjusting the output power of the aerosol generating device.

[0070] It is understandable that when the electrical circuits of the heating elements 121 at different locations are connected, that is, when the heating element 12 generates heat through different heating elements 121, the overall heat generation of the heating element 12 will also be different when the output power of different heating elements 121 is different.

[0071] It should be noted that the first heating element 1211, the second heating element 1212, and the third heating element 1213 are heating elements 121 located at three different positions.

[0072] The output power of the heating element 12 ranges from 5W to 150W. For example, it can be 5W, 10W, 15W, 20W, 25W, 30W, 35W, 40W, 45W, 50W, 55W, 60W, 65W, 70W, 75W, 80W, 85W, 90W, 95W, 100W, 105W, 110W, 115W, 120W, 125W, 130W, 135W, 140W, 145W, 150W, etc.

[0073] In related technologies, the heating element of aerosol generators can only output power at a specific level. During use, when the user inhales with a small inhalation, the output power is too high, resulting in a high aerosol temperature; conversely, when inhaling with a large inhalation, the output power is insufficient, resulting in less aerosol generation and a less satisfying experience. To cater to users with different inhalation methods, an increasing number of aerosol generators with varying output power have been developed, further complicating user choices. In conclusion, the user experience and purchase experience of aerosol generators in these technologies still have significant room for improvement.

[0074] The aerosol generating device of this application embodiment includes a heating element 12 comprising multiple heating sections 121 and multiple pins 122. One pin 122 is connected to all heating sections 121, and the remaining pins 122 are connected to each heating section 121 in a corresponding manner. The connection of each heating section 121 to form a single unit via one pin 122 facilitates the stable and reliable placement of each heating section 121 within the atomization channel 11a. Furthermore, by switching the electrical connection state of each heating section 121, at least some of the heating sections 121 form a parallel circuit with the battery cell of the aerosol generating device; and / or, at least some of the heating sections 121 form a series circuit with the battery cell of the aerosol generating device. That is, the overall resistance of the heating element 12 can be changed to switch the output power of the aerosol generating device, enabling the aerosol generating device to output different power levels. Thus, the aerosol generating device can provide different output power according to different suction methods, which is beneficial for generating sufficient aerosol and controlling the aerosol at a suitable temperature, thereby improving the user's suction experience.

[0075] Furthermore, the aerosol generating device of this application embodiment can provide different output powers, thereby adapting to users using different suction methods. This helps to reduce the specifications of aerosol generating devices on the market, reduce the difficulty of selection for users, and thus improve the user's purchasing experience.

[0076] Furthermore, the aerosol generating device of this application embodiment selectively activates each heating element 121 based on the user's suction needs. For a specific heating element 121, the heating element 121 may work alternately as the user's suction needs change, and the heating element 121 will not be in working state for a long time, thereby helping to extend the service life of the heating element 121.

[0077] In some embodiments, please refer to Figure 5 The resistance value of any heating element 121 is different from the resistance values ​​of the other heating elements 121.

[0078] In other words, any two of the heating elements 121 can be selected, and the resistance values ​​of these two heating elements 121 are different.

[0079] For example, the resistance of the first heating element 1211 is 0.8Ω, the resistance of the second heating element 1212 is 0.6Ω, and the resistance of the third heating element 1213 is 0.4Ω.

[0080] When only the electrical circuit of the first heating element 1211 is turned on, the total resistance of the heating element 12 is 0.8Ω.

[0081] When only the electrical circuit of the second heating element 1212 is turned on, the total resistance of the heating element 12 is 0.6Ω.

[0082] When only the electrical circuit of the third heating element 1213 is turned on, the total resistance of the heating element 12 is 0.4Ω.

[0083] When the first heating element 1211 and the second heating element 1212 are connected in parallel and the electrical circuit of the third heating element 1213 is cut off, the total resistance of the heating element 12 is approximately 0.34Ω.

[0084] When the first heating element 1211 and the third heating element 1213 are connected in parallel and the electrical circuit of the second heating element 1212 is cut off, the total resistance of the heating element 12 is approximately 0.27Ω.

[0085] When the second heating element 1212 and the third heating element 1213 are connected in parallel and the electrical circuit of the first heating element 1211 is cut off, the total resistance of the heating element 12 is 0.24Ω.

[0086] When the first heating element 1211, the second heating element 1212 and the third heating element 1213 are connected in parallel, the total resistance of the heating element 12 is approximately 0.11Ω.

[0087] When the first heating element 1211 and the second heating element 1212 are connected in series, the total resistance of the heating element 12 is 1.4Ω.

[0088] When the first heating element 1211 and the third heating element 1213 are connected in series, the total resistance of the heating element 12 is 1.2Ω.

[0089] When the second heating element 1212 and the third heating element 1213 are connected in series, the total resistance of the heating element 12 is 1.0Ω.

[0090] In this embodiment, given a fixed total number of heating elements 121, the number of heating elements 12 that can provide different resistance values ​​is greater. This allows the aerosol generating device to output more different power values, which in turn allows the aerosol generating device to more precisely control the amount and temperature of aerosols generated, thus better meeting the user's needs.

[0091] In some embodiments, please refer to Figure 5 At least two heating elements 121 must have the same resistance. This can be either all heating elements 121 having the same resistance, or only a portion of the heating elements 121 having the same resistance.

[0092] For example, the resistance of the first heating element 1211, the second heating element 1212 and the third heating element 1213 is 1.2Ω.

[0093] When the electrical circuit of any one of the first heating element 1211, the second heating element 1212 and the third heating element 1213 is turned on, the total resistance of the heating element 12 is 1.2Ω.

[0094] When any two of the first heating element 1211, the second heating element 1212, and the third heating element 1213 are connected in parallel, the total resistance of the heating element 12 is 0.6Ω.

[0095] When the first heating element 1211, the second heating element 1212 and the third heating element 1213 are connected in parallel, the total resistance of the heating element 12 is 0.48Ω.

[0096] When any two of the first heating element 1211, the second heating element 1212, and the third heating element 1213 are connected in series, the total resistance of the heating element 12 is 2.4Ω.

[0097] In this embodiment, at least some of the heating elements 121 have the same specifications, which helps to reduce the number of different types of heating elements 121, thereby improving the production efficiency of the heating element 12.

[0098] Furthermore, when this type of heating element 12 is output in parallel and the number of heating elements 121 that need to be activated is determined, it is not necessary to consider which specific heating element 121 is activated. Thus, the control method is relatively simple and easy to implement. At the same time, when the aerosol generating device outputs at the same power for a long time, the heating elements 121 can also work alternately, which helps to extend the service life of each heating element 121.

[0099] In some embodiments, please refer to Figure 5 Each heating element 121 extends circumferentially along the atomization channel 11a; or,

[0100] The projection of each heating element 121 onto a plane perpendicular to the axis of the atomizing channel 11a is semi-enclosed.

[0101] Here, as Figure 5 As shown, each heating element 121 has a ring-shaped structure, and the ring is not a closed ring, but a ring with an opening 121a.

[0102] It should be noted that the ring structure referred to here is not limited to a circular ring; it can be a circular ring, a square ring, or various other ring structures.

[0103] In this embodiment, under the condition that the size of the heating element 121 along the axial direction of the atomization channel 11a is fixed, it is beneficial to increase the layout area of ​​a single heating element 121, thereby improving the output power of a single heating element 121, and thus improving the atomization efficiency of the aerosol generation matrix.

[0104] In addition, the heating element 121 has a better circumferential coverage effect on the atomization channel 11a, and the aerosol generation matrix is ​​heated more evenly.

[0105] In some embodiments, please refer to Figure 5 Each pin 122 extends along the axial direction of the atomization channel 11a.

[0106] In this way, the pins 122 can be arranged using the openings 121a of each heating element 121, which helps to reduce the difficulty of arranging the pins 122 and improve the installation efficiency of the heating element 12.

[0107] In some embodiments, please refer to Figure 3 and Figure 5 The two ends of the atomizing channel 11a in the axial direction are the air inlet 11b and the air outlet 11c, respectively.

[0108] The first subshell 21 is also provided with a suction air passage 21a. The atomization channel 11a is connected to the suction air passage 21a through the air outlet 11c.

[0109] For example, in the direction from the air outlet 11c to the air inlet 11b, the first heating element 1211, the second heating element 1212 and the third heating element 1213 are arranged in sequence at intervals. The first pin 1221 needs to pass through the second heating element 1212 and the third heating element 1213 in sequence, and the second pin 1222 also needs to pass through the third heating element 1213.

[0110] Understandably, the size of the heating element 121, which is closer to the air intake end 11b, is more affected by the size of each pin 122.

[0111] From the air outlet 11c to the air inlet 11b, the extension angle of each heating element 121 along the circumferential direction of the atomization channel 11a gradually decreases. That is, along the circumferential direction of the atomization channel 11a, the size of the opening 121a of the third heating element 1213 is greater than the size of the opening 121a of the second heating element 1212, which is greater than the size of the opening 121a of the first heating element 1211.

[0112] In this way, while ensuring that the heating element 121 closest to the air inlet 11b can accommodate the installation of each pin 122, the area of ​​other heating elements 121 arranged along the circumferential direction of the atomization channel 11a can be increased as much as possible, which is beneficial to improving the total output power of the heating element 12.

[0113] In some embodiments, please refer to Figure 3 and Figure 4 The aerosol generating device also includes a housing assembly 20 and an air inlet valve. The atomizing assembly 10 is located inside the housing assembly 20. The housing assembly 20 has a main air inlet 22a and at least one auxiliary air inlet 22b. The air inlet valve is located at the auxiliary air inlet 22b.

[0114] The main air inlet 22a and each of the auxiliary air inlets 22b are used to connect the atmosphere and the atomization channel 11a.

[0115] The main air intake 22a and each auxiliary air intake 22b can be located in the first sub-shell 21 or in the second sub-shell 22. This application does not impose any restrictions on this.

[0116] For example, the main air intake 22a and each auxiliary air intake 22b can be located at the end of the first sub-shell 21 away from the second sub-shell 22.

[0117] For example, please refer to Figure 3 and Figure 4 The main air intake 22a and each auxiliary air intake 22b can be located at the end of the second sub-shell 22 away from the first sub-shell 21.

[0118] When the user inhales with a small inhale, the air inlet valve is closed. Air from outside the aerosol generator can enter through the main air inlet 22a, then through the air inlet 11b into the atomization channel 11a, carrying the aerosol within the atomization channel 11a into the user's mouth via the suction air passage 21a. In this state, air is minimally introduced into the aerosol generator through the auxiliary air inlet 22b. This facilitates the creation of negative pressure at the nozzle of the aerosol generator, allowing the user to experience some suction resistance and mitigating the problem of air suction caused by low negative pressure.

[0119] When the user takes a deep drag, they can open the air intake valve. At this time, the aerosol generator uses the main air intake port 22a and the auxiliary air intake port 22b to work together to increase the air intake volume of the aerosol generator, thereby improving the difficulty of inhalation caused by excessive suction resistance. Furthermore, by increasing the air intake volume, it is beneficial to increase the amount of vapor and reduce the temperature of the aerosol, thus improving the taste of the aerosol.

[0120] There are no restrictions on the type of intake valve.

[0121] In some embodiments, the intake valve is a solenoid valve. Thus, the opening or closing of the intake valve can be controlled by acquiring the air pressure value within the start-up air passage of the aerosol generator. Here, the solenoid valve can be either an on / off valve or a proportional valve. An on / off valve is a valve that can only achieve two states: open or closed. A proportional valve is a valve that, once open, can also adjust its opening degree.

[0122] In some embodiments, the air intake valve can also be manually controlled. Users can manually open or close the air intake valve according to actual suction conditions, thus enabling more accurate control based on the user's specific needs.

[0123] In some embodiments, please refer to Figure 6 and Figure 7 The intake valve includes a resilient valve disc 30, which includes a connecting body 31 and a plurality of elastic bodies 32. The connecting body 31 is annular and seals against the wall of the auxiliary intake port 22b. Each elastic body 32 is arranged circumferentially along the connecting body 31. One end of any elastic body 32 is located on the inner wall of the connecting body 31, and the other end extends radially inward along the connecting body 31 and forms a free end 32b.

[0124] Here, the connector 31 and the multiple elastic bodies 32 can be an integrally formed structure.

[0125] When the air pressure in the starting air passage reaches a certain value, the air pressure difference between the two ends of the elastic valve disc 30 is sufficient to push the free end 32b of the elastic body 32 to produce elastic deformation and swing along the axis of the auxiliary air intake hole 22b, thereby realizing the automatic opening of the intake valve.

[0126] Of course, as the air pressure in the starting airway decreases, the air pressure difference between the two ends of the elastic valve disc 30 will also gradually decrease, and the free end 32b of the elastic body 32 can recover its elastic deformation and reset, thereby realizing the automatic closing of the intake valve.

[0127] In this embodiment, the structure of the air intake valve is relatively simple, and it can automatically open or close according to the pressure difference generated by the user's aerosol suction. Thus, the control method is relatively simple, which helps to reduce the cost of the aerosol generation device, and at the same time, it is more convenient for users to use.

[0128] The method of sealing the connector 31 with the wall of the auxiliary air inlet 22b is not limited.

[0129] For example, the connector 31 may be disposed in the auxiliary air intake 22b in an interference fit manner.

[0130] For example, the connector 31 is disposed at the auxiliary air intake 22b, and a sealing material is filled between the connector 31 and the auxiliary air intake 22b. The sealing material may be, for example, a sealing ring, sealant, etc.

[0131] In some embodiments, please refer to Figure 6 and Figure 7 Along the circumference of the auxiliary air inlet 22b, there is a gap between two adjacent elastic bodies 32.

[0132] It is understandable that in this embodiment, even when the air intake valve is closed, a small amount of gas will still pass through the gap between the two elastomers 32 and be supplied to the aerosol generating device through the auxiliary air intake port 22b.

[0133] In this embodiment, during the process of elastic deformation or recovery of elastic deformation, the elastic body 32 avoids interference with adjacent elastic bodies 32 by utilizing the gap between the two elastic bodies 32. This helps reduce the probability of interference between the two elastic bodies 32. That is, it is beneficial for each elastic body 32 to undergo elastic deformation or recover elastic deformation, thereby improving the reliability of the intake valve.

[0134] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 The auxiliary air intake 22b includes a first sub-hole 22b1 and a second sub-hole 22b2 that are axially connected. The two ends of the first sub-hole 22b1 are connected to the atmosphere and the second sub-hole 22b2, respectively. The diameter of the first sub-hole 22b1 is larger than the diameter of the second sub-hole 22b2 and a stepped surface 22b3 is formed at the connection between the two. The connecting body 31 is disposed in the first sub-hole 22b1 and is sealed and fitted to the stepped surface 22b3.

[0135] In this way, when installing the elastic valve disc 30, the stepped surface 22b3 can be regarded as the position for positioning the elastic valve disc 30. This makes it easier for assembly personnel to confirm whether the elastic valve disc 30 is installed in place, thereby helping to improve the yield of the aerosol generation device.

[0136] Furthermore, limiting the elastic valve disc 30 by the stepped surface 22b3 helps reduce the probability of displacement, thereby improving the stability of the elastic valve disc 30 installed in the auxiliary air intake port 22b.

[0137] It should be noted that there are no restrictions on the specific structure of the sealing fit between the connector 31 and the step surface 22b3.

[0138] For example, the connector 31 may directly abut against the step surface 22b3.

[0139] For example, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 The resilient valve disc 30 also includes an adhesive backing 33, which is sandwiched between the connector 31 and the stepped surface 22b3. The adhesive backing 33 helps to improve the sealing performance between the connector 31 and the stepped surface 22b3, and also helps to improve the stability and reliability of the connector 31 in the auxiliary air inlet 22b.

[0140] In some embodiments, please refer to Figure 3 and Figure 4 The auxiliary air intake 22b has an inlet 22b4, and the auxiliary air intake 22b communicates with the atmosphere through the inlet 22b4; wherein, along the radial inward direction of the connecting body 31, the surface of the elastic body 32 on the side closer to the atmosphere gradually moves away from the surface where the inlet 22b4 is located.

[0141] Here, inlet 22b4 is the opening at the end of the first sub-hole 22b1 that is away from the second sub-hole 22b2.

[0142] In this embodiment, the surface of the elastomer 32 closest to the atmosphere can be regarded as a guide surface. It can be understood that the airflow direction is approximately parallel to the axis of the auxiliary air intake port 22b, and the surface forms an acute angle with the airflow direction. This facilitates the elastic deformation of the elastomer 32, thereby enabling the air intake valve to open.

[0143] The surface of the elastomer 32 facing the atmosphere can be a plane, but this plane is inclined relative to the axial direction of the auxiliary air inlet 22b. In this way, the structure of the outer wall of the elastomer 32 is relatively simple, which facilitates the molding of the elastomer 32.

[0144] Please see Figure 4 and Figure 7 The surface of the elastomer 32 facing the atmosphere can also be curved. For example, as the connecting body 31 moves radially inward, the speed at which the surface of the elastomer 32 facing the atmosphere moves away from the surface of the inlet 22b4 gradually decreases. Here, when the surface of the elastomer 32 facing away from the atmosphere is perpendicular to the axial direction of the inlet 22b4, at the same location on the elastomer 32, compared to an embodiment where the surface of the elastomer 32 facing the atmosphere is planar, the dimension of the elastomer 32 in the axial direction of the inlet 22b4 is smaller, thus making it more advantageous for the elastomer 32 to undergo elastic deformation.

[0145] In some embodiments, please refer to Figure 3 and Figure 4 The cross-sectional area of ​​the auxiliary air inlet 22b is different from that of the main air inlet 22a.

[0146] The auxiliary air intake 22b is mainly used to assist the main air intake 22a in intake. Specifically, the cross-sectional area of ​​the flow channel of the auxiliary air intake 22b can be larger than that of the main air intake 22a; of course, the cross-sectional area of ​​the flow channel of the auxiliary air intake 22b can also be smaller than that of the main air intake 22a.

[0147] Understandably, the auxiliary air inlet 22b is mainly used to increase the air intake during large-aperture suction. Therefore, appropriately increasing the cross-sectional area of ​​the flow channel of the auxiliary air inlet 22b is beneficial to increasing the air intake of the aerosol generating device during large-aperture suction. During small-aperture suction, the main air inlet 22a with its small cross-sectional area will not allow too much airflow to enter, ensuring that the suction resistance within the suction channel 21a is not too low, which helps to improve the problem of air suction caused by low suction resistance.

[0148] In some embodiments, the cross-sectional area of ​​the auxiliary air intake 22b may also be equal to the cross-sectional area of ​​the main air intake 22a.

[0149] In some embodiments, please refer to Figure 3 and Figure 4 At least one auxiliary air intake port 22b includes a first auxiliary air intake port 22c and a second auxiliary air intake port 22d. The elastic valve 30 provided in the first auxiliary air intake port 22c is a first elastic valve 40, and the elastic valve 30 provided in the second auxiliary air intake port 22d is a second elastic valve 50.

[0150] The cross-sectional area of ​​the flow channel of the second auxiliary air inlet 22d is different from that of the first auxiliary air inlet 22c. Specifically, the auxiliary air inlet 22b with a larger flow channel cross-sectional area is the second auxiliary air inlet 22d.

[0151] By setting at least two auxiliary air inlets 22b, it is beneficial to meet the suction needs of larger openings.

[0152] It is understandable that a larger intake requires a larger air volume when drawing aerosols through a larger opening. Therefore, setting the cross-sectional area of ​​the flow channel of the second auxiliary air inlet 22d to be larger than that of the first auxiliary air inlet 22c is beneficial to meeting the air intake requirements of the aerosol generation device when drawing aerosols through a larger opening.

[0153] Of course, the cross-sectional area of ​​the flow channel of the second auxiliary air inlet 22d can also be the same as that of the cross-sectional area of ​​the flow channel of the second auxiliary air inlet 22c.

[0154] In some embodiments, please refer to Figure 3 and Figure 4The thickness of the second elastic valve flap 50 is different from the thickness of the first elastic valve flap 40. Specifically, the thickness of the second elastic valve flap 50 is greater than the thickness of the first elastic valve flap 40.

[0155] For example, the thickness dimension of the first resilient valve disc 40 is as follows: Figure 4 As shown in D1, the thickness dimension of the second elastic valve disc 50 is as follows: Figure 4 As shown in D2.

[0156] The second auxiliary air inlet 22d is used to supply air when the user uses a larger suction port. Compared with the first elastic valve 40, the second elastic valve 50 is thickened to prevent the second elastic valve 50 from switching to the open state too early.

[0157] Here, the first auxiliary air inlet 22c and the second auxiliary air inlet 22d work together to match different suction needs, thereby completing the air supply for the aerosol generation device and improving the user's suction experience.

[0158] In this embodiment, the ease of elastic deformation of each elastic valve flap 30 is changed by controlling the thickness of each elastic valve flap 30. In this way, the first elastic valve flap 40 and the second elastic valve flap 50 can be made of the same material. This helps to reduce the types of materials required for the aerosol generating device, thereby improving the production efficiency of the aerosol generating device.

[0159] In some embodiments, the thickness of the first elastic valve flap 40 and the thickness of the second elastic valve flap 50 may be the same.

[0160] In this way, by adjusting the material or hardness of the first elastic valve disc 40 and the second elastic valve disc 50, it is also possible to make them open under different pressure differences.

[0161] Here, the first elastic valve flap 40 and the second elastic valve flap 50 have the same thickness, so they can be produced using the same production tools, which helps to reduce the production cost of the aerosol generating device.

[0162] This application provides a control method for an aerosol generating device. The aerosol generating device can be operated according to the steps of this control method.

[0163] Please see Figures 1 to 3 The aerosol generating device includes a housing assembly 20 and an atomizing assembly 10. The atomizing assembly 10 is located inside the housing assembly 20. The housing assembly 20 has a suction air passage 21a and an activation air passage. The suction air passage 21a is connected to the atomizing channel 11a, and the user draws in the aerosol generated in the atomizing channel 11a through the suction air passage 21a.

[0164] When the airway is activated and the microphone senses the airflow when the user inhales, it controls the start and stop of the aerosol generation device.

[0165] When a user inhales the aerosol, the gas in the suction channel 21a is drawn away by the user, thus creating a negative pressure in the suction channel 21a. As a result, the air pressure in the atomization channel 11a is higher than the air pressure in the suction channel 21a. The aerosol generated in the atomization channel 11a flows to the suction channel 21a under the action of the air pressure difference and is then inhaled by the user.

[0166] In related technologies, aerosol generators control the activation and deactivation of the atomizing components by detecting the air pressure within the activation airway. When activated, the aerosol generator outputs a fixed power. However, with this control method, the output power is too high when the user inhales in small puffs, resulting in a higher aerosol temperature; conversely, the output power is insufficient when inhaling in large puffs, leading to a smaller aerosol production and a less satisfying inhalation experience. In other words, the inhalation experience of aerosol generators in these technologies has significant room for improvement.

[0167] Based on this, please refer to Figure 8 The control method of the aerosol generating device in this application includes:

[0168] S100: Set multiple preset pressure zones, with each preset pressure zone corresponding to one output power.

[0169] It is understandable that different preset air pressure zones correspond to different output power.

[0170] S200: Obtain the air pressure value in the start-up airway.

[0171] Here, the air pressure value can be the specific value of the air pressure in the starting airway that can be obtained directly, or it can be the difference between the specific value and the atmospheric pressure, i.e., the negative pressure value.

[0172] There are no restrictions on how the air pressure value is obtained.

[0173] For example, the aerosol generating device may include a microphone through which the air pressure value can be obtained.

[0174] For example, the aerosol generating device can also directly obtain the pressure value through a pressure sensor.

[0175] For example, the aerosol generating device can also acquire the flow rate value of the gas in the starting airway through a flow rate sensor, and the acquisition module of the aerosol generating device converts the flow rate value into a gas pressure value.

[0176] S300: Determine the preset pressure zone corresponding to the pressure value, and determine the output power corresponding to the preset pressure zone as the target output power.

[0177] S400: Controls the atomizing components to output power at the target output power.

[0178] It should be noted that the preset pressure zone can be a single point value or a range of values.

[0179] In other words, different air pressure values ​​may result in the same or different target output power for the atomizing component 10.

[0180] For example, the adjustment of the atomizing component 10 between different target output powers can be stepped. For instance, when the atomizing component 10 can only output at four target power levels of 5W, 6W, 7W, and 8W, based on a specific air pressure value, the target output power of the atomizing component 10 can only be any one of 5W, 6W, 7W, and 8W. That is to say, the preset air pressure zone is a range of values. When the air pressure value changes within the range of the preset air pressure zone, the target output power remains unchanged. However, when the air pressure value changes to another preset air pressure zone, the target output power is adjusted accordingly.

[0181] For example, the atomizing component 10 can also be infinitely adjustable between different target output powers. For instance, if the atomizing component 10 can output any target output power within the range of 5W to 8W, then the target output power of the atomizing component 10 will change as the air pressure changes. Here, it refers to the preset air pressure zone being a single-point value.

[0182] It is understandable that the negative pressure value is relatively small when the user takes a small puff, and relatively large when taking a large puff. This allows the target output power of the atomizing component 10 to be lower when taking a small puff than when taking a large puff.

[0183] The control method of the aerosol generating device in this application embodiment sets multiple preset pressure zones, each corresponding to an output power; it acquires the pressure value within the starting airway; it determines the preset pressure zone corresponding to the pressure value and sets the output power corresponding to that preset pressure zone as the target output power; thereby controlling the atomizing component 10 to output at the target output power. When the pressure value within the starting airway differs significantly, the target output power of the atomizing component 10 also varies. Thus, when the user takes small puffs, controlling the atomizing component 10 to output at a lower target output power helps maintain the aerosol at a suitable temperature; while when taking large puffs, controlling the atomizing component 10 to output at a higher target output power helps generate sufficient aerosol, thereby meeting the user's inhalation needs. Therefore, the control method of the aerosol generating device in this application embodiment helps improve the user's inhalation experience.

[0184] In some embodiments, please refer to Figure 9 , Figure 9 This is a schematic diagram of an aerosol generating device according to an embodiment of this application. The aerosol generating device further includes a battery cell. The atomizing component 10 includes a plurality of heating elements 121, at least some of which form a parallel circuit with the battery cell. The electrical circuit between each heating element 121 and the battery cell can be selectively turned on or off. Controlling the atomizing component 10 to output a target output power includes:

[0185] Based on the target output power, determine the target resistance value of the atomizing component 10;

[0186] Switch the electrical connection state of each heating element 121 to adjust the resistance of the atomizing assembly 10 to the target resistance value.

[0187] The target resistance value refers to the resistance value that the atomizing component 10 needs to provide in order to output the target output power under the condition that the cell voltage remains unchanged.

[0188] It is understandable that when different numbers of heating elements 121 are connected in the electrical circuit, that is, the number of heating elements 121 connected in parallel to the battery cell changes, the overall resistance of the heating element 12 will also change.

[0189] It is understandable that when the electrical circuits of the heating elements 121 at different locations are connected, that is, when the output is through different heating elements 121, and the resistance values ​​of different heating elements 121 are different, the overall resistance of the heating element 12 will also change.

[0190] It should be noted that the multiple heating elements 121 include, for example, the first heating element 1211, the second heating element 1212, and the third heating element 1213 mentioned above. The first heating element 1211, the second heating element 1212, and the third heating element 1213 are heating elements 121 at three different locations.

[0191] In this embodiment, by connecting or disconnecting the electrical circuit between the battery cell and each heating element 121, the heating element 12 can output different target output powers, i.e., it is not necessary to adjust the output voltage of the battery cell. Connecting or disconnecting the electrical circuit is a switching action, and adjusting the output voltage of the battery cell requires outputting a dynamically changing electrical signal. Furthermore, the output voltage of the battery cell itself has a certain degree of instability, making it more difficult to adjust. Therefore, the control method of this embodiment helps to reduce the difficulty of adjusting the target output power of the atomizing assembly 10.

[0192] Furthermore, in this embodiment, each heating element 121 can work alternately, which helps to extend the service life of each heating element 121 and reduce the probability of each heating element 121 malfunctioning. As a result, users can use it with more peace of mind, which helps to improve the user experience.

[0193] As mentioned above, at least part of the heating element 121 can also form a series circuit with the battery cell. This is beneficial to increase the maximum value of the target resistance that the atomizing component 10 can provide, that is, to reduce the minimum value of the target output power of the atomizing component 10. In this way, the working range of the atomizing component 10 can be expanded, and the aerosol generating device can provide appropriate output power to heat the atomized aerosol generating matrix according to the user's needs.

[0194] In some embodiments, please refer to Figure 9 Since the resistance values ​​of each heating element 121 are the same, the electrical connection states of each heating element 121 are switched to adjust the resistance value of the atomizing assembly 10 to the target resistance value, including:

[0195] The electrical circuits of different numbers of heating elements 121 are turned on to adjust the resistance of the atomizing component 10 to the target resistance value.

[0196] As mentioned above, the resistance of the first heating element 1211, the second heating element 1212, and the third heating element 1213 is 1.2Ω.

[0197] When only one of the three heating elements 121 is turned on, the total resistance of the heating element 12 is 1.2Ω.

[0198] When only any two of the three heating elements 121 are turned on and they form a parallel circuit with the battery cell, the total resistance of the heating element 12 is 0.6Ω.

[0199] When only any two of the three heating elements 121 are turned on and the two form a series circuit with the battery cell, the total resistance of the heating element 12 is 2.4Ω.

[0200] For example, when it is necessary to control the heating element 12 to output a target resistance value of 1.2Ω, the first heating element 1211, the second heating element 1212 and the third heating element 1213 can work alternately, which helps to improve the service life of each heating element 121 and reduce the probability of each heating element 121 failing. As a result, it is more worry-free for users and helps to improve the user experience.

[0201] Furthermore, since all heating elements 121 are of the same specification, it is beneficial to reduce the variety of heating elements 121 in the heating element 12, thereby improving the production efficiency of the heating element 12.

[0202] Furthermore, based on this type of heating element 12, by conducting the electrical circuits of different numbers of heating elements 121, the heating element 12 can be made to work with different output power. This control method is relatively simple and easy to implement.

[0203] In some embodiments, please refer to Figure 9Each heating element 121 has a different resistance value. That is, if any two heating elements 121 are randomly selected, the resistance values ​​of these two heating elements 121 will be different.

[0204] Switching the electrical connection states of each heating element 121 to adjust the resistance of the atomizing assembly 10 to the target resistance value includes:

[0205] By activating electrical circuits of heating elements 121 in different numbers and / or locations, the resistance of the atomizing assembly 10 is adjusted to the target resistance value.

[0206] As mentioned earlier, the resistance of the first heating element 1211 is 0.8Ω, the resistance of the second heating element 1212 is 0.6Ω, and the resistance of the third heating element 1213 is 0.4Ω. At least 10 different target resistance values ​​can be obtained. Thus, with a fixed number of heating elements 121, the heating element 12 can provide a greater number of target resistance values. This allows the heating element 12 to output more different target output powers, enabling the aerosol generating device to more precisely adjust the target output power of the heating element 12 and better match the user's suction needs.

[0207] In some embodiments, the aerosol generating device further includes a battery cell electrically connected to the atomizing assembly 10, controlling the atomizing assembly 10 to output power at a target output power, including:

[0208] Adjust the output voltage of the battery cell to adjust the output power of the atomizing component 10 to the target output power.

[0209] In this way, the resistance provided by the atomizing component 10 does not need to be changed, and the output voltage of the battery cell can be adjusted through the control module, thereby adjusting the output power of the atomizing component to the target output power. This adjustment method is relatively simple and easy to control.

[0210] In some embodiments, obtaining the air pressure value within the initiation airway includes:

[0211] At the start of each suction inhalation, the air pressure value in the inhalation airway is obtained.

[0212] Here, when the user inhales the aerosol in one breath, the target output power of the atomizing component 10 is matched based on the air pressure value in the airway at the beginning of each breath, and the atomizing component 10 is controlled to output at the target output power. The target output power of the atomizing component 10 remains unchanged until the inhalation ends.

[0213] This simplifies the control method of the atomizing component 10 and helps to improve the problem of low reliability of the aerosol generating device caused by overly complex control methods.

[0214] In some embodiments, obtaining the air pressure value within the initiation airway includes:

[0215] During each suctioning stroke, the air pressure value within the airway is continuously acquired multiple times.

[0216] Here, when the user inhales the aerosol in one breath, the air pressure value in the starting airway is dynamically acquired during each breath, thereby achieving dynamic control of the target output power of the atomizing component 10.

[0217] In this way, even if the user changes the suction intensity during each inhalation, the aerosol generating device can promptly identify the user's suction needs and adjust the target output power of the atomizing component 10 accordingly to meet the user's suction requirements and improve the user's suction experience.

[0218] In this embodiment, the aerosol generating device can more precisely control the target output power of the atomizing component 10, thereby further improving the user's inhalation experience.

[0219] In some embodiments, please refer to Figure 3 and Figure 4 The housing assembly 20 is provided with a main air inlet and at least one auxiliary air inlet 22b, and the control method further includes:

[0220] Adjust the intake volume of the auxiliary air intake port 22b based on the air pressure value.

[0221] Understandably, the greater the user's suction force, the more the air intake of the aerosol generating device can be appropriately increased by adjusting the air intake of the auxiliary air intake port 22b, thereby reducing the suction resistance of the user's aerosol suction and improving the user's suction experience.

[0222] In some embodiments, please refer to Figure 3 and Figure 4 The aerosol generating device also includes an air inlet valve, which is located at the auxiliary air inlet 22b. Based on the air pressure value, the valve adjusts the air intake volume through the auxiliary air inlet 22b, including:

[0223] If the air pressure is lower than the preset threshold, the air intake valve will be opened;

[0224] If the air pressure is not lower than the preset threshold, the air intake valve will be closed.

[0225] There is no restriction on the specific value of the preset threshold. It can be designed according to actual needs.

[0226] If the air pressure value is lower than the preset threshold, it means that the user is sucking too hard. At this time, the air inlet valve is opened to increase the air intake of the aerosol generating device, which helps to reduce the user's sucking resistance. In addition, the increased air intake helps to increase the amount of smoke.

[0227] Once the air pressure reaches the preset threshold, it indicates that the user's suction force is relatively small and there is no need for the auxiliary air inlet 22b to provide too much air intake. At this time, the air intake valve is closed to ensure that the user has a certain suction resistance when suctioning, which helps to improve the problem of air suction caused by low suction resistance.

[0228] In this embodiment, the intake volume of the auxiliary air intake port 22b is controlled by the intake valve. The intake valve can be linked with the control module of the aerosol generation device, which helps to improve the automation level of the aerosol generation device.

[0229] There are no restrictions on the type of intake valve.

[0230] For example, the intake valve is a solenoid valve. Thus, by acquiring the air pressure value within the starting air passage, the opening or closing of the intake valve is controlled. Here, the solenoid valve can be either an on / off valve or a proportional valve. An on / off valve is a valve that can only achieve two states: open or closed. A proportional valve is a valve that, once open, can also adjust its opening degree.

[0231] In some embodiments, please refer to Figure 3 and Figure 4 The intake valve includes a resilient valve disc 30, which includes a connecting body 31 and multiple elastic bodies 32. The connecting body 31 is annular and seals against the wall of the auxiliary intake port 22b. Each elastic body 32 is arranged circumferentially along the connecting body 31. One end of any elastic body 32 is located on the inner wall of the connecting body 31, and the other end extends radially inward along the connecting body 31 to form a free end 32b. Based on the negative pressure value, the intake volume of the auxiliary intake port 22b is adjusted, including:

[0232] If the air pressure is lower than the preset threshold, the air intake valve will open automatically;

[0233] If the air pressure is not lower than the preset threshold, the air intake valve will be automatically closed.

[0234] Here, the connector 31 and the multiple elastic bodies 32 can be an integrally formed structure.

[0235] When the air pressure in the start-up airway is lower than the preset threshold, the air pressure difference between the two ends of the elastic valve disc 30 is sufficient to push the free end 32b of the elastic body 32 to produce elastic deformation and swing along the axis of the auxiliary air intake port 22b, thereby realizing the automatic opening of the intake valve.

[0236] Of course, as the air pressure in the start-up airway rises to a level not lower than the preset threshold, the air pressure difference between the two ends of the elastic valve disc 30 will gradually decrease, and the free end 32b of the elastic body 32 can recover its elastic deformation and thus reset, thereby achieving automatic closure of the intake valve.

[0237] In this embodiment, the structure of the air intake valve is relatively simple, and it can automatically open or close according to the air pressure difference generated by suction. Thus, the control method is relatively simple, which helps to reduce the cost of the aerosol generating device, and at the same time, it is more convenient for users to use.
