[0037] The application will be described in further detail below with reference to the drawings and specific embodiments.
[0038] The application provides an aerosol generating device, referring to Figure 1 The aerosol generating device comprises a power assembly and the atomizer 100 of any one of the embodiments of the application.
[0039] It should be noted that when the aerosol generating device adopts the atomizer 100 of any one of the embodiments of the application, the aerosol generating device has all the advantages of the atomizer 100, and the specific advantages will be described in detail below.
[0040] It should be noted that the specific type of the aerosol generating device of the embodiments of the application is not limited. For example, the aerosol generating device can be a medical atomization device, an air humidifier, or an electronic cigarette or other atomization device.
[0041] The power assembly is mainly used for supplying power to the atomizer 100 and controlling the opening or closing of the entire aerosol generating device and the like, and the atomizer 100 is mainly used for accommodating the aerosol generating substrate and heating and atomizing the aerosol generating substrate after being powered on. The aerosol generating substrate includes but is not limited to materials used for medical, health, health, beauty, and the like.
[0042] In some embodiments, the atomizer 100 and the power assembly can be mechanically and electrically connected together in the axial direction. Further, the atomizer 100 and the power assembly can be connected together in a detachable manner such as magnetic attraction connection, threaded connection, buckle connection, etc. The atomizer 100 and the power assembly can be replaced or upgraded separately, thereby reducing the replacement cost and saving user expenses. Of course, in other embodiments, the atomizer 100 and the power assembly can also be connected together in a non-detachable manner.
[0043] In addition, the atomizer 100 and / or the power assembly are not limited to a cylindrical shape, and can also be an elliptical cylindrical shape or a square column shape or other shapes.
[0044] The application also provides an atomizer, referring to Figures 1 to 3 The atomizer 100 has a first liquid storage compartment 10a and a plurality of liquid passage channels, and the first liquid storage compartment 10a is used for accommodating the aerosol generating substrate.
[0045] The atomizer 100 comprises an atomization core 21, and the first liquid storage compartment 10a is communicated with the atomization core 21 through any one of the liquid passage channels. That is, the aerosol generating substrate in the first liquid storage compartment 10a can enter the atomization core and be heated and atomized to generate aerosol for the user to use.
[0046] The plurality of liquid downcomers include a first liquid downcomer 101 and a second liquid downcomer 102, and along the depth direction of the first liquid storage compartment 10a, the inlet of the second liquid downcomer 102 is higher than the inlet of the first liquid downcomer 101. In this way, when the liquid level height of the aerosol generating substrate in the first liquid storage compartment 10a is higher than the inlet of the second liquid downcomer 102, the aerosol generating substrate in the first liquid storage compartment 10a can be supplied through the first liquid downcomer 101 and the second liquid downcomer 102, and as the user uses, the amount of aerosol generating substrate in the first liquid storage compartment 10a gradually decreases, so the liquid level height in the first liquid storage compartment 10a gradually decreases, and after the liquid level height in the first liquid storage compartment 10a is lower than the inlet of the second liquid downcomer 102, the aerosol generating substrate in the first liquid storage compartment 10a can only be supplied through the first liquid downcomer 101.
[0047] It should be noted that the depth direction of the first liquid storage compartment 10a is the height direction of the atomizer 100. The height direction of the atomizer 100 is shown in Figure 1 、 Figure 3 or Figure 4 .
[0048] Here, it should be noted that the extension direction of each liquid downcomer is not limited.
[0049] For example, each liquid downcomer can extend in a direction perpendicular to the depth direction of the first liquid storage compartment 10a. That is, the first liquid downcomer 101 and the second liquid downcomer 102 are arranged in the depth direction of the first liquid storage compartment 10a.
[0050] For another example, each liquid downcomer can also extend along the depth direction of the first liquid storage compartment 10a. Here, the top end of the first liquid downcomer 101 and the top end of the second liquid downcomer 102 respectively communicate with the first liquid storage compartment 10a, and the aerosol generating substrate can flow along each liquid downcomer under the action of gravity, thereby realizing continuous liquid supply.
[0051] It should be noted that in the embodiments of the present application, the orientation terms such as "up", "down", "top", "bottom" and the like are based on the height direction of the atomizer 100. Specifically, please refer to the identification in Figure 1 、 Figure 3 or Figure 4 for understanding.
[0052] The power supply assembly is electrically connected with the atomization core 21, and the power supply assembly is configured to supply electric energy to the atomization core 21, and the atomization core 21 is configured to heat the atomized aerosol generating substrate to generate an aerosol.
[0053] In the initial stage of use of the atomizer 100, the liquid level of the aerosol generating substrate in the first liquid storage chamber 10a is higher than the inlet of the second lower liquid channel 102, and the first liquid storage chamber 10a can be supplied with liquid at least through the first lower liquid channel 101 and the second lower liquid channel 102. During this period, the volume of gas in the first liquid storage chamber 10a is relatively small, the liquid supply rate is slow, and the first lower liquid channel 101 and the second lower liquid channel 102 supply liquid at the same time, thereby facilitating the guarantee of the liquid supply amount.
[0054] With the use of the atomizer 100, the proportion of the volume of gas in the first liquid storage chamber 10a gradually increases, and the liquid supply rate gradually increases. After the liquid level of the aerosol generating substrate in the first liquid storage chamber 10a is lower than the inlet of the second lower liquid channel 102, the second lower liquid channel 102 exits the liquid supply function, and the liquid supply through the first lower liquid channel 101 can also meet the liquid supply amount. At the same time, the second lower liquid channel 102 does not supply liquid, which is conducive to improving the problem of liquid leakage caused by excessive liquid supply in the later stage of use of the atomizer 100.
[0055] In related technologies, the heights of the multiple lower liquid channels of the atomizer are consistent, and the lower liquid channels all participate in liquid supply at the same time during the entire use cycle of the atomizer. For the atomizer with such a structure, with the use of the atomizer, the gas in the liquid storage chamber increases, and in the later stage of use, the multiple lower liquid channels participate in liquid supply at the same time, which is prone to cause the problem of excessive liquid supply, thereby causing the problem of liquid leakage caused by suction of the atomizer.
[0056] The atomizer 100 of the embodiment of the present application includes the first lower liquid channel 101 and the second lower liquid channel 102, and the height of the inlet of the second lower liquid channel 102 is higher than the height of the inlet of the first lower liquid channel 101. In the initial stage of use of the atomizer 100, the liquid level of the aerosol generating substrate in the first liquid storage chamber 10a is higher than the inlet of the second lower liquid channel 102, and the first liquid storage chamber 10a can be supplied with liquid at least through the first lower liquid channel 101 and the second lower liquid channel 102. During this period, the volume of gas in the first liquid storage chamber 10a is relatively small, the liquid supply rate is slow, and the first lower liquid channel 101 and the second lower liquid channel 102 supply liquid at the same time, thereby facilitating the guarantee of the liquid supply amount. With the use of the atomizer 100, the proportion of the volume of gas in the first liquid storage chamber 10a gradually increases, and the liquid supply rate gradually increases. After the liquid level of the aerosol generating substrate in the first liquid storage chamber 10a is lower than the inlet of the second lower liquid channel 102, that is, in the later stage of use of the atomizer 100, the second lower liquid channel 102 exits the liquid supply function, and the liquid supply through the first lower liquid channel 101 can also meet the liquid supply amount. At the same time, the second lower liquid channel 102 does not supply liquid, which is conducive to improving the problem of liquid leakage caused by excessive liquid supply in the later stage of use of the atomizer 100.
[0057] It should be noted that the relationship between the cross-sectional area of the flow passage of the first lower liquid channel 101 and the cross-sectional area of the flow passage of the second lower liquid channel 102 is not limited.
[0058] In some embodiments, the cross-sectional area of the flow passage of the first lower liquid passage 101 and the cross-sectional area of the flow passage of the second lower liquid passage 102 can be equal.
[0059] In other embodiments, the cross-sectional area of the flow passage of the second lower liquid passage 102 is greater than the cross-sectional area of the flow passage of the first lower liquid passage 101.
[0060] It can be understood that, in the initial stage of use of the atomizer 100, the volume fraction of gas in the first liquid storage chamber 10a is small, and the liquid downflow rate is relatively slow. By appropriately increasing the cross-sectional area of the flow passage of the second lower liquid passage 102, the liquid supply amount in the initial stage of use can be ensured.
[0061] With the use of the atomizer 100, the volume fraction of gas in the first liquid storage chamber 10a gradually increases, and the liquid downflow rate gradually increases. After the liquid level of the aerosol generating substrate in the first liquid storage chamber 10a is lower than the inlet of the second lower liquid passage 102, the second lower liquid passage 102 stops the liquid downflow function, and the liquid supply through the first lower liquid passage 101 can also meet the liquid supply amount. The cross-sectional area of the flow passage of the first lower liquid passage 101 is relatively small, which is beneficial to control the liquid supply amount in the later stage of use, thereby reducing the probability of the atomizer 100 having a suction leakage problem.
[0062] In summary, in the present embodiment, the cross-sectional area of the flow passage of the first lower liquid passage 101 is designed to be smaller than the cross-sectional area of the flow passage of the second lower liquid passage 102, which is beneficial to balance the influence of the increase of the volume of gas in the first liquid storage chamber 10a on the liquid supply speed, and is beneficial to improve the consistency of the liquid supply of the atomizer 100 in the entire use cycle.
[0063] In some embodiments, the diameter of the cross-sectional area of the flow passage of the first lower liquid passage 101 is 1.2mm-1.8mm. For example, it can be 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, etc.
[0064] In this way, the diameter of the cross-sectional area of the flow passage of the first lower liquid passage 101 will not be less than 1.2mm, and in the initial stage of use of the atomizer 100, the first lower liquid passage 101 can supply sufficient aerosol generating substrate, which is beneficial to ensure the liquid supply amount. At the same time, the diameter of the cross-sectional area of the flow passage of the first lower liquid passage 101 will not be greater than 1.8mm, which is beneficial to control the liquid supply amount of the first lower liquid passage 101 in the later stage of use of the atomizer 100, thereby reducing the probability of the first lower liquid passage 101 supplying too much liquid and causing a suction leakage problem.
[0065] In some embodiments, the flow passage cross-sectional area of the second lower liquid passage 102 is 1.5mm-2mm. For example, it can be 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, etc.
[0066] In this way, the flow passage cross-sectional area of the second lower liquid passage 102 is appropriate. In the initial stage of use of the atomizer 100, the second lower liquid passage 102 can supply sufficient aerosol generating substrate, which is conducive to ensuring the liquid supply amount. At the same time, it is also conducive to controlling the liquid supply amount of the second lower liquid passage 102 within an appropriate range, thereby reducing the probability of liquid leakage caused by excessive liquid supply of the second lower liquid passage 102.
[0067] In some embodiments, referring to Figure 4 , the height difference between the lowest point of the inlet of the second lower liquid passage 102 and the bottom wall of the first liquid storage chamber 10a accounts for 40%-60% of the height of the first liquid storage chamber 10a. For example, it can be 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, etc.
[0068] Exemplarily, when each lower liquid passage extends along the depth direction of the first liquid storage chamber 10a, the lowest point of the inlet of the second lower liquid passage 102 is the top end of the second lower liquid passage 102. At this time, the height difference between the lowest point of the inlet of the second lower liquid passage 102 and the bottom wall of the first liquid storage chamber 10a is the height difference between the top end of the second lower liquid passage 102 and the bottom wall of the first liquid storage chamber 10a. Specifically, as shown in D1 of Figure 4 , the height of the first liquid storage chamber 10a is shown as D2 in Figure 4 .
[0069] It can be understood that when the liquid level height in the first liquid storage chamber 10a is not higher than the lowest point of the inlet of the second lower liquid passage 102, the second lower liquid passage 102 completely exits the liquid supply.
[0070] In this way, the height at which the lowest point of the inlet of the second lower liquid passage 102 is located is reasonable. On the one hand, the height at which the lowest point of the inlet of the second lower liquid passage 102 is located is not too low, so that the second lower liquid passage 102 can timely exit the liquid supply function, which is conducive to further improving the problem of liquid leakage caused by excessive liquid supply. On the other hand, the height at which the lowest point of the inlet of the second lower liquid passage 102 is located is also not too high, so that the second lower liquid passage 102 does not exit the liquid supply function too early, which is conducive to meeting the liquid supply amount of the atomizer 100 in the initial stage of use.
[0071] In some embodiments, the atomizer 100 further comprises a housing 11 and an atomization assembly 20, the atomization assembly 20 comprises an atomization core 21, the housing 11 is provided with a cavity 11a, the cavity 11a is open at the bottom side along the height direction of the atomizer 100, and the atomization assembly 20 is arranged at the open side of the cavity 11a and defines a first liquid storage chamber 10a with the cavity 11a, and each liquid inlet channel is arranged in the atomization assembly 20.
[0072] Here, the top wall of the atomization assembly 20 constitutes the bottom wall of the first liquid storage chamber 10a.
[0073] In the present embodiment, the first liquid inlet channel 101 and the second liquid inlet channel 102 with different inlet heights are directly formed by the atomization assembly 20, and during assembly of the atomizer 100, only the housing 11 and the atomization assembly 20 need to be assembled to form the first liquid storage chamber 10a, so that the assembly steps of the atomizer 100 are simpler, which is conducive to improving the production efficiency of the atomizer 100.
[0074] It can be understood that after the aerosol generating substrate in the first liquid storage chamber 10a is used up, the housing 11 and the atomization assembly 20 can be replaced as a whole, and the power supply assembly can still be used.
[0075] In some embodiments, referring to Figures 2 to 4 , the atomizer 100 further comprises a housing assembly 10 and an atomization assembly 20, the atomization assembly 20 comprises an atomization core 21, the housing assembly 10 comprises a housing 11 and a cover 12, the housing 11 is provided with a cavity 11a, the cavity 11a is open at the bottom side along the height direction of the atomizer 100, the cover 12 is arranged at the open side of the cavity 11a and defines a first liquid storage chamber 10a with the cavity 11a, and the atomization assembly 20 is arranged at the side of the cover 12 away from the first liquid storage chamber 10a.
[0076] In this way, the housing assembly 10 forms the first liquid storage chamber 10a, and after the aerosol generating substrate in the first liquid storage chamber 10a is used up, a new housing assembly containing aerosol generating substrate can be replaced, while the atomization assembly 20 can be reused, so as to be conducive to reducing the use cost of the user.
[0077] Here, the forming mode of each liquid inlet channel is not limited.
[0078] Specifically, referring to Figure 3 and Figure 4 , the cover 12 is provided with a first liquid inlet hole 12a and a second liquid inlet hole 12b, and the atomization assembly 20 is provided with a first flow guide channel 22a and a second flow guide channel 23a.
[0079] Exemplarily, at least part of the liquid inlet channels are arranged in the cover 12, or each liquid inlet channel is arranged in the atomization assembly 20.
[0080] Here, the first flow guide channel 22a and the first lower liquid hole 12a are taken as examples. The first flow guide channel 22a can be provided in the first lower liquid hole 12a; when one end of the first flow guide channel 22a does not exceed the inlet of the first lower liquid hole 12a, at this time, the aerosol generating substrate in the first liquid storage compartment 10a is supplied in sequence through the first lower liquid hole 12a and the first flow guide channel 22a, and therefore, the first lower liquid hole 12a can be understood as the first lower liquid passage 101, that is, the first lower liquid passage 101 is provided in the cover 12; when one end of the first flow guide channel 22a exceeds the inlet of the first lower liquid hole 12a, at this time, the aerosol generating substrate in the first liquid storage compartment 10a can directly enter the first flow guide channel 22a through the inlet of the first flow guide channel 22a, and therefore, the first flow guide channel 22a can be understood as the first lower liquid passage 101, that is, the first lower liquid passage 101 is provided in the atomization assembly 20.
[0081] It can be understood that the second lower liquid passage 102 can also be understood in the above-mentioned manner. That is, the second lower liquid passage 102 can also be provided in the cover 12 or in the atomization assembly 20.
[0082] In this embodiment, the shell assembly 10 and the atomization assembly 20 cooperate to facilitate the formation of the first lower liquid passage 101 and the second lower liquid passage 102 during the replacement of the shell assembly 10 as a whole, so that the aerosol generating substrate stored in the shell assembly 10 can enter the atomization assembly 20 to be heated and atomized by the atomization core 21.
[0083] In some embodiments, referring to Figure 4 , the shell assembly 10 further comprises a sealing member 13, which can be a sealing film, a sealing plug or the like. The first lower liquid hole 12a and the second lower liquid hole 12b are each provided with a sealing member 13.
[0084] In this way, when the shell assembly 10 is stored alone, the first lower liquid hole 12a and the second lower liquid hole 12b are sealed by the sealing member 13, so as to prevent the aerosol generating substrate in the first liquid storage compartment 10a from leaking out.
[0085] In some embodiments, referring to Figure 4 and Figure 5 , the atomization assembly 20 is provided with a first protruding column 22 and a second protruding column 23, the first protruding column 22 surrounds to form the first flow guide channel 22a, and the second protruding column 23 surrounds to form the second flow guide channel 23a.
[0086] The first protruding column 22 is provided in the first lower liquid hole 12a, and the first flow guide channel 22a constitutes at least part of the first lower liquid passage 101; the second protruding column 23 is provided in the second lower liquid hole 12b, and the second lower liquid hole 12b constitutes the second lower liquid passage 102.
[0087] That is, at least a portion of the inlet of the first flow guide channel 22a protrudes beyond the inlet of the first lower liquid hole 12a, and the inlet of the second flow guide channel 22b does not protrude beyond the inlet of the second lower liquid hole 12b.
[0088] When the shell assembly 10 and the atomization assembly 20 are assembled, the first protrusion 22 can pierce or push out the seal 13 in the first lower liquid hole 12a, and the second protrusion 23 can pierce or push out the seal 13 in the second lower liquid hole 12b, so that the lower liquid channels are communicated, and the aerosol generating substrate in the first liquid storage compartment 10a can flow to the atomization core 21.
[0089] It can be understood that, since the inlet of the first lower liquid channel 101 is low in height, when the first lower liquid channel 101 extends in the depth direction of the first liquid storage compartment 10a, that is, the first lower liquid hole 12a also extends in the depth direction of the first liquid storage compartment 10a, the height of the top end of the first lower liquid hole 12a is also low. In this embodiment, by protruding at least a portion of the top end of the first protrusion beyond the top end of the first lower liquid hole 12a, the first protrusion 22 is more conducive to piercing or pushing out the seal 13 in the first lower liquid hole 12a.
[0090] In some embodiments, referring to Figure 2 and Figure 3 , the atomization assembly 20 is provided with a second liquid storage compartment 20a, and any lower liquid channel is in communication with the second liquid storage compartment 20a.
[0091] The second liquid storage compartment 20a can also store a certain amount of aerosol generating substrate.
[0092] For example, the second liquid storage compartment 20a can directly store liquid aerosol generating substrate, or an adsorbent material can be arranged in the second liquid storage compartment 20a to adsorb a certain amount of aerosol generating substrate.
[0093] In a specific embodiment, the second liquid storage compartment 20a can store 2 ml of aerosol generating substrate, and the first liquid storage compartment 10a can store 10 ml of aerosol generating substrate.
[0094] The first liquid storage compartment 10a is in communication with the second liquid storage compartment 20a through the lower liquid channels, and the second liquid storage compartment 20a is in liquid communication with the atomization core 21.
[0095] In some embodiments, referring to Figure 4 and Figure 5 , the top end of the first protrusion 22 and the top end of the second protrusion 23 are each provided with a sharp protrusion 20b, so that the first protrusion 22 and the second protrusion 23 are more conducive to piercing or pushing out the respective seals 13.
[0096] In some embodiments, referring to Figure 2 andFigure 3 、 Figure 5 The face where the top end of the first lower liquid hole 12a is located is coplanar with the face where the bottom wall of the first liquid storage compartment 10a is located. The top end of the first flow guide channel 22a is provided with a liquid inlet area 22b. The lowest point of the liquid inlet area 22b is not higher than the top end of the first lower liquid hole 12a.
[0097] In this embodiment, the first lower liquid channel 101 extends along the depth direction of the first liquid storage compartment 10a.
[0098] The liquid inlet area 22b refers to the total opening area of the top end of the first flow guide channel 22a. That is, the aerosol generating substrate in the first liquid storage compartment 10a can enter the first flow guide channel 22a through any position of the liquid inlet area 22b.
[0099] The lowest point of the liquid inlet area 22b is not higher than the top end of the first lower liquid hole 12a. That is, the lowest point of the liquid inlet area 22b is lower than the top end of the first lower liquid hole 12a, or the lowest point of the liquid inlet area 22b is flush with the top end of the first lower liquid hole 12a.
[0100] In this way, the aerosol generating substrate in the first liquid storage compartment 10a can enter the first flow guide channel 22a through the liquid inlet area 22b, which is conducive to reducing the residual amount of the aerosol generating substrate in the first liquid storage compartment 10a. In this way, it is conducive to reducing waste and thus reducing the use cost of the user. At the same time, since the aerosol generating substrate is basically not left in the first liquid storage compartment 10a, when the user replaces the shell assembly 10, it is also conducive to reducing the risk of liquid leakage of the shell assembly 10, thereby reducing the risk of liquid leakage to the user's hands or clothes, thereby improving the user's experience.
[0101] In some embodiments, referring to Figure 2 and Figure 3 、 Figure 5 The circumferential wall of the first protruding column 22 is provided with a notch 22c. The notch 22c constitutes at least part of the liquid inlet area 22b. The top end of the first protruding column 22 protrudes beyond the top end of the first lower liquid hole 12a. The bottom side of the notch 22c is not higher than the top end of the first lower liquid hole 12a.
[0102] It can be understood that, under the condition that the height dimension of the shell assembly 10 is constant, by reducing the height of the face where the bottom surface of the first liquid storage compartment 10a is located, it is conducive to improving the liquid storage capacity of the first liquid storage compartment 10a. However, in this way, the distance between the face where the bottom wall of the first liquid storage compartment 10a is located and the bottom surface of the shell assembly 10 is relatively small, and the overall height of the first lower liquid hole 12a is relatively low.
[0103] In the embodiment, the top end of the first protruding column 22 can be beyond the top end of the first lower liquid hole 12a. In this way, the size of the first protruding column 22 is not limited by the height of the first lower liquid hole 12a, so that the structure such as the sharp protrusion 20b can be arranged on the first protruding column 22. At the same time, the height of the lowest point of the liquid inlet area 22b is reduced by the notch 22c, so that the aerosol generating substrate in the first liquid storage compartment 10a can enter the first flow channel 22a through the liquid inlet area 22b.
[0104] Specifically, the aerosol generating substrate at the bottom of the first liquid storage compartment 10a can enter the first flow channel 22a through the notch 22c.
