Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to an aerosol generating device and aerosol generating equipment. Background Technology

[0002] An aerosol generating device is a device capable of atomizing an aerosol generating matrix and generating aerosols. Related aerosol generating devices store a liquid aerosol generating matrix in a reservoir, and use a heating element to heat and atomize the matrix to generate aerosols. Since the aerosol generating matrix in the reservoir is gradually consumed, it needs to be replenished when the matrix is ​​low. Related aerosol generating devices include a reservoir bottle, and the aerosol generating matrix stored in the bottle can be added to the reservoir, effectively extending the device's operating time. However, existing liquid guiding structures between the reservoir and the reservoir bottle are relatively complex, requiring additional valves and other adjustment mechanisms, making manufacturing and assembly complex and costly; furthermore, users need to manually operate the adjustment mechanisms to guide the aerosol generating matrix from the reservoir bottle into the reservoir, making it inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an improved aerosol generating device and aerosol generating equipment, addressing at least one deficiency mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: to provide an aerosol generating device, which includes a shell and an atomizing component;

[0005] The outer shell has a first cavity and a second cavity. The first cavity is used to store the aerosol generation matrix, and the atomizing component is disposed in the second cavity. The first cavity and the second cavity are connected and arranged side by side.

[0006] The outer casing includes a bottom surface and a side surface connected to each other, and the side surface includes a first side surface and a second side surface disposed opposite to each other; the first side surface is closer to the first cavity than the second side surface.

[0007] The bottom surface and the first side surface are non-supporting surfaces.

[0008] In some embodiments, the non-resting surface includes a smooth curved surface or a slope.

[0009] In some embodiments, the smooth surface includes an arc surface or a conical surface.

[0010] In some embodiments, the bottom surface includes an arcuate surface or a conical surface.

[0011] In some embodiments, the outer shell includes a shell body and a baffle connected to the shell body. The baffle divides the space enclosed by the shell body into a first cavity and a second cavity. The baffle is provided with a liquid inlet hole that penetrates the baffle, and the first cavity is connected to the second cavity through the liquid inlet hole.

[0012] In some embodiments, the penetration direction of the first cavity through the bottom surface and the penetration direction of the liquid inlet through the baffle are perpendicular to each other.

[0013] In some embodiments, the housing is formed with a suction nozzle, and in the horizontal direction, the second cavity is closer to the suction nozzle than the first cavity.

[0014] In some embodiments, the aerosol generating device further includes a power supply component disposed in the second cavity, located on the vertical side of the atomizing component, and capable of forming an electrical connection with the atomizing component.

[0015] This utility model also provides an aerosol generating device, which includes a liquid storage bottle and the aerosol generating device described in any of the above claims, wherein the liquid storage bottle is installed in the first cavity of the outer shell of the aerosol generating device.

[0016] In some embodiments, the first cavity extends through the bottom surface, forming an opening on the bottom surface for mounting a liquid storage bottle.

[0017] This invention has at least the following advantages: Since the bottom surface and the first side surface of the outer shell are non-supporting surfaces, the aerosol generating device, under natural support without external force, can only be tilted forward or backward, or tilted towards the second cavity (to the left), so as to realize the function of the first cavity replenishing the liquid storage chamber of the second cavity. Therefore, the natural tilting state of the aerosol generating device can be used to replenish the liquid storage chamber of the second cavity, eliminating the need for additional complex valves or other parts inside the outer shell to activate the replenishment function. This design achieves the replenishment function while offering advantages such as simple manufacturing process, low manufacturing cost, and convenient operation. Attached Figure Description

[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Please see Figures 1 to 4 This utility model discloses an embodiment of an aerosol generating device, including an aerosol generating apparatus. The aerosol generating apparatus includes a housing 20 and an atomizing component 30. For example... Figure 4 As shown, the outer shell 20 has a first cavity 201 and a second cavity 202. An atomizing component 30 is disposed within the second cavity 202. A liquid storage chamber is formed within the second cavity 202, which stores a liquid aerosol generating matrix. The atomizing component 30 heats and atomizes the aerosol generating matrix to generate aerosol for the user to inhale. The first cavity 201 stores the aerosol generating matrix. The first cavity 201 and the second cavity 202 are connected and arranged side-by-side. When the aerosol generating matrix in the liquid storage chamber within the second cavity 202 is consumed, it can be replenished through the first cavity 201.

[0030] The first cavity 201 and the second cavity 202 are arranged side by side, meaning that the projected portions of the first cavity 201 and the second cavity 202 overlap or completely overlap in a certain direction. For example, the projected portions of the first cavity 201 and the second cavity 202 may overlap or completely overlap along a horizontal direction. The horizontal direction can be referenced... Figures 1 to 4 The L and R directions are marked above, where L represents the left side of the image and R represents the right side. The terms "horizontal," "left," and "right" used in this text can be referenced from these directions. Figures 1 to 4 The LR direction designation in the text. The term "vertical" as used in this article can be found in [reference needed]. Figures 1 to 4 The VV direction is indicated in the text. In some embodiments, the first cavity 201 and the second cavity 202 may have partially overlapping projections along the horizontal direction, meaning that the first cavity 201 and the second cavity 202 may have different heights, or the first cavity 201 and the second cavity 202 may have the same height but be offset from each other in height. The projections of the first cavity 201 and the second cavity 202 along the horizontal direction may completely overlap. In one embodiment, the first cavity 201 and the second cavity 202 have the same height and are aligned in the height direction.

[0031] In one embodiment, the aerosol generating device further includes a storage bottle 10. A first chamber 201 can be used to mount the storage bottle 10. The storage bottle 10 is used to store liquid aerosol generating matrix. Since each atomization consumes the aerosol generating matrix in the storage chamber, the storage bottle 10 can replenish the aerosol generating matrix in the storage chamber of the second chamber 202, thereby improving the endurance of the aerosol generating device. That is, the first chamber 201 achieves the function of storing the aerosol generating matrix by mounting the storage bottle 10 therein. Furthermore, the storage bottle 10 can be detachably mounted in the first chamber 201 so that the storage bottle 10 can be removed and replenished with aerosol generating matrix.

[0032] Since aerosol generating devices need to be stored and placed away when not in use, the surface on which they are placed and in contact with the aerosol generating device, i.e., the surface where the aerosol generating device rests in its natural resting state, is defined as the placement surface 40. This placement surface 40 can be a surface parallel to the ground, such as a tabletop or shelf surface, i.e., a horizontal plane. When the aerosol generating device is placed on the placement surface 40 without any external force, it can be considered to be in a natural resting state. Figure 4Using the orientation as a reference, when the aerosol generating device tilts to the right, the first chamber 201 is closer to the placement surface 40 relative to the second chamber 202. That is, the storage bottle 10 is closer to the placement surface 40 relative to the second chamber 202, and the height of the storage bottle 10 relative to the placement surface 40 is lower than the height of the second chamber 202 relative to the placement surface 40. Therefore, the liquid in the storage bottle 10 cannot enter the second chamber 202. When the aerosol generating device tilts to the left, the second chamber 202 is closer to the placement surface 40 relative to the first chamber 201. That is, the second chamber 202 is closer to the placement surface 40 relative to the storage bottle 10, and the height of the storage bottle 10 relative to the placement surface 40 is greater than the height of the second chamber 202 relative to the placement surface 40. Therefore, the liquid in the storage bottle 10 can enter the second chamber 202, and the liquid in the second chamber 202 will not flow towards the storage bottle 10. Please refer to [link to relevant documentation]. Figure 5 and Figure 6 , Figure 5 and Figure 6 This illustration shows the aerosol generating device tilted forward and backward onto the placement surface 40, with the forward and backward direction perpendicular to the plane constructed along the LRV direction. (Example) Figure 5 and 6 As shown, when the aerosol generating device is tilted forward or backward, the liquid level 101 in the storage bottle 10 extends along the length of the storage bottle 10, and the liquid in the storage bottle 10 can flow horizontally into the second chamber 202. Therefore, when the aerosol generating device is tilted towards the direction closer to the first chamber 201 (right side), the liquid replenishment function of the storage bottle 10 is difficult to achieve; when the aerosol generating device is tilted towards the direction closer to the second chamber 202 (left side), and when tilted forward or backward, the liquid replenishment function of the storage bottle 10 can be achieved.

[0033] Please see Figures 1 to 4 The outer casing 20 includes a bottom surface 21 and side surfaces that are connected but not parallel. Specifically, the outer casing 20 has a nozzle 205. The atomizing assembly 30 heats and atomizes the aerosol generating matrix, and the resulting aerosol overflows from the nozzle 205, allowing the user to inhale the aerosol. The bottom surface 21 of the outer casing 20 is located at the end of the outer casing 20 away from the nozzle 205. The side surfaces include a first side surface 221 and a second side surface 222 that are arranged opposite to each other. The first side surface 221 and the second side surface 222 may be arranged parallel to each other. In the horizontal direction, the first side surface 221 is closer to the first cavity 201 than the second side surface 222, and the second side surface 222 is closer to the second cavity 202 than the first side surface 221. For example... Figures 1 to 4 In the embodiment shown, the first cavity 201 is offset to the right side of the outer shell 20, and the second cavity 202 is offset to the left side of the outer shell 20; the left side of the outer shell 20 is the second side 222, and the right side of the outer shell 20 is the first side 221.

[0034] Among them, the bottom surface 21 and the first side surface 221 are non-supporting surfaces. Specifically, a non-supporting surface is a surface relative to a supporting surface. The supporting surface of the aerosol generating device refers to the surface of the aerosol generating device that can stably contact the placement surface 40 without the assistance of external force. That is, the aerosol generating device stably contacts the placement surface 40 with its supporting surface when naturally placed. Conversely, the non-supporting surface of the aerosol generating device refers to the surface of the aerosol generating device that cannot stably contact the placement surface 40 without the assistance of external force. However, when an external force is applied, the aerosol generating device can also stably contact the placement surface 40 with its non-supporting surface. The external force can be a support force provided by humans or a support force provided by other solids.

[0035] In summary, since the bottom surface 21 and the first side surface 221 of the outer casing 20 are non-supporting surfaces, the aerosol generating device, under natural resting conditions without external force, can only be tilted forward or backward, or tilted towards the second cavity 202 (to the left), to achieve the function of the first cavity 201 replenishing the liquid storage chamber of the second cavity 202. Therefore, the natural tilting state of the aerosol generating device can be used to replenish the liquid storage chamber of the second cavity 202, eliminating the need for additional complex valves or other components inside the outer casing 20 to activate the replenishment function. This approach offers advantages such as simple manufacturing process, low manufacturing cost, and convenient operation while still achieving the replenishment function. When replenishment is not required, the aerosol generating device can be erected and supported against other objects.

[0036] Furthermore, the non-supporting surface can include a smooth curved surface or an inclined surface. That is, the non-supporting surface can be a smooth curved surface or an inclined surface, but is not limited to either. The non-supporting surface can also have other shapes, for example, multiple protrusions of different heights can be provided on the non-supporting surface, each protrusion can be a smooth curved surface, a plane, or an inclined surface; the height of these protrusions can decrease or increase sequentially in the same direction; or, these protrusions can be irregularly arranged. In summary, the shape of the non-supporting surface allows the aerosol generating device to be in an unbalanced and unstable state when it contacts the placement surface 40 with the non-supporting surface without the aid of external force. Therefore, the aerosol generating device cannot stably contact the placement surface 40 with the non-supporting surface without the aid of external force. Figure 4 As shown, in the first embodiment, the bottom surface 21 includes a smooth curved surface. When the aerosol generating device is in the upright position, this smooth curved surface is in contact with the placement surface 40. Figure 9 As shown, in the second embodiment, the bottom surface 21 includes two inclined surfaces facing opposite directions. The inclined surfaces are inclined relative to the placement surface 40, and the inclined surfaces form an angle greater than 0° and less than 90° with the placement surface 40. The inclined surfaces do not contact the placement surface 40.

[0037] In one embodiment, since the bottom surface 21 of the housing 20 includes a smooth curved surface or an inclined surface, while the placement surface 40 of the aerosol generating device is typically a horizontal surface (e.g., a tabletop), the contact area between the smooth curved surface and the horizontal surface is smaller than the contact area between the flat bottom surface and the horizontal surface, and can be considered as point contact. Therefore, when the aerosol generating device contacts the placement surface 40 with its bottom surface 21, it is difficult for the aerosol generating device to maintain balance, thereby increasing the difficulty of vertically placing the aerosol generating device. Figure 3 and Figure 4 (The diagram illustrates the aerosol generating device in an upright position). Because the bottom surface 21 is designed with an inclined surface that does not contact the placement surface 40, the contact area between the inclined bottom surface 21 and the placement surface 40 is smaller than that between a flat bottom surface and a horizontal surface, which increases the difficulty of maintaining the balance of the aerosol generating device in an upright position. Since the first side surface 221 near the first cavity 201 includes at least one of a smooth curved surface and an inclined surface, it is also more difficult for the aerosol generating device to maintain its balance when its first side surface 221 contacts the placement surface 40, thereby increasing the difficulty of tilting the aerosol generating device towards the direction (right side) closer to the first cavity 201. Due to the difficulty of placing the aerosol generating device upright and the increased difficulty of tilting it towards the right side (closer to the first chamber 201), the aerosol generating device, under natural resting conditions without external force, can only be tilted forward or backward, or tilted towards the left side (closer to the second chamber 202), to enable the first chamber 201 to replenish the liquid storage chamber of the second chamber 202. Therefore, the natural tilting state of the aerosol generating device can be used to replenish the liquid storage chamber of the second chamber 202, eliminating the need for additional complex valves or other components inside the outer casing 20 to activate the replenishment function. This approach offers advantages such as simple manufacturing process, low manufacturing cost, and convenient operation while still achieving the replenishment function. When replenishment is not required, the aerosol generating device can be stood upright and supported against other objects.

[0038] Specifically, the smooth surface can include an arc surface or a conical surface. That is, the bottom surface 21 can be an arc surface or a conical surface, or it can also include surfaces of other shapes; similarly, the first side surface 221 can also be an arc surface or a conical surface, or it can also include surfaces of other shapes. For example Figures 1 to 6 In the illustrated embodiment, the bottom surface 21 and the first side surface 221 each include an arc surface. For example... Figure 7 In another embodiment shown, the bottom surface 21 includes a conical surface. The conical surface has a pointed tip, and the bottom surface 21 can only contact the placement surface 40 by means of this pointed tip. The contact area between the bottom surface 21 and the placement surface 40 is very small, making it difficult to place the aerosol generating device vertically.

[0039] like Figure 3 and Figure 4 ,as well as Figure 6As shown, the interior of the outer casing 20 has a liquid inlet 204 between the first cavity 201 and the second cavity 202. This inlet 204 connects the first cavity 201 and the second cavity 202, respectively, allowing liquid from the storage bottle 10 to enter the second cavity 202 through this inlet 204. When the aerosol generating device is tilted towards the second cavity 202 (to the left), the second cavity 202 is closer to the placement surface 40 than the first cavity 201; that is, the second cavity 202 is positioned below the first cavity 201. At this time, under gravity, the storage bottle 10 can inject liquid into the second cavity 202. However, all the liquid in the storage bottle 10 will rush into the inlet 204, resulting in a large injection volume / injection rate, which may increase the risk of liquid leakage. To obtain a suitable injection volume, such as... Figure 2 As shown, in some embodiments, similar to the bottom surface 21 and the first side surface 221, the second side surface 222 may also include at least one of a smooth curved surface and an inclined surface. Similarly, the smooth curved surface of the second side surface 222 may also include at least one of an arc surface and a conical surface. Since the second side surface 222 near the second cavity 202 also includes a smooth curved surface, when the aerosol generating device contacts the placement surface 40 with its second side surface 222, it is also more difficult for the aerosol generating device to maintain balance, thereby increasing the difficulty of tilting the aerosol generating device towards the direction (left side) closer to the second cavity 202. Due to the increased difficulty of tilting the aerosol generating device towards the direction (left side) closer to the second cavity 202, the aerosol generating device can only be tilted back and forth in a natural resting state without external force to realize the function of the liquid storage bottle 10 replenishing the liquid storage chamber of the second cavity 202. Figure 6 As shown, when the liquid is tilted forward or backward, the liquid in the storage bottle 10 will flow horizontally towards the inlet port 204. The liquid volume / injection rate is relatively smaller than the liquid volume / injection rate when the aerosol generating device is tilted to the left, which can reduce the risk of liquid leakage.

[0040] like Figures 1 to 4 As shown, in some embodiments, the first cavity 201 extends through the bottom surface 21, forming an opening 210 on the bottom surface 21 for mounting the liquid storage bottle 10. Specifically, the first cavity 201 is generally a vertically extending cavity; and the first cavity 201 is located to the right of the second cavity 202 in the horizontal direction. The liquid storage bottle 10 can be inserted into the first cavity 201 through the opening 210 on the bottom surface 21. Since the first cavity 201 extends through the bottom surface 21, the area of ​​the bottom surface 21 is reduced, further reducing the contact area between the bottom surface 21 and the placement surface 40, thereby further increasing the difficulty of vertically placing the aerosol generating device.

[0041] like Figure 4As shown, in some embodiments, the outer casing 20 includes a casing body 200 and a baffle 203 connected to the casing body 200. The baffle 203 divides the space enclosed by the casing body 200 into a first cavity 201 and a second cavity 202. The casing body 200 has a suction nozzle 205. The outer surface of the casing body 200 includes a side surface and a bottom surface 21. Specifically, the first cavity 201 is located on the right side of the baffle 203, and the second cavity 202 is located on the left side of the baffle 203. The baffle 203 has a liquid inlet hole 204 that penetrates the baffle 203, and the first cavity 201 is connected to the second cavity 202 through the liquid inlet hole 204.

[0042] like Figure 4 As shown, in some embodiments, the penetration direction X of the first cavity 201 through the bottom surface 21 and the penetration direction Y of the inlet hole 204 through the baffle wall 203 are not parallel. Therefore, the mouth of the storage bottle 10 is not directly opposite the inlet hole 204, and when the storage bottle 10 replenishes liquid into the storage cavity of the second cavity 202, a suitable injection volume / injection rate can be obtained. Conversely, if the penetration direction X of the first cavity 201 through the bottom surface 21 is parallel to the penetration direction Y of the inlet hole 204 through the baffle wall 203, then the mouth of the storage bottle 10 is directly opposite the inlet hole 204, which can easily lead to an excessive injection volume / injection rate and pose a risk of liquid leakage.

[0043] Specifically, the penetration direction X of the first cavity 201 through the bottom surface 21 and the penetration direction Y of the liquid inlet hole 204 through the baffle wall 203 can be perpendicular to each other; or, the penetration direction X of the first cavity 201 through the bottom surface 21 and the penetration direction Y of the liquid inlet hole 204 through the baffle wall 203 can also form an angle greater than 0° and less than 180°. For example Figures 1 to 4 As shown, in some embodiments, in the horizontal direction, the second cavity 202 is closer to the nozzle 205 than the first cavity 201. That is, the nozzle 205 is offset to one side of the horizontal direction of the housing 20. As a result, the center of gravity of the housing 20 is biased towards the side closer to the second cavity 202 (left side). Due to the offset of the center of gravity of the housing 20, it is more difficult to place the aerosol generating device upright when not subjected to external force; and because the center of gravity of the housing 20 is biased towards the side closer to the second cavity 202 (left side), it is more difficult to tilt the aerosol generating device towards the direction closer to the first cavity 201 (right side) when not subjected to external force, thereby further increasing the difficulty of placing the aerosol generating device upright and tilting it to the right.

[0044] like Figure 3As shown, in some embodiments, the aerosol generating device further includes a power supply component 50, which is disposed within the second cavity 202, located on the vertical side of the atomizing component 30, and is electrically connected to the atomizing component 30. Specifically, the power supply component 50 is used to provide power to the atomizing component 30 and to control the atomization switch, atomization power, etc. of the atomizing component 30. The power supply component 50 may include components such as a battery cell 501 and a control circuit board 502. The battery cell 501 can provide power to the atomizing component 30. The control circuit board 502 can control the atomization switch, atomization power, etc. of the atomizing component 30. Since the power supply component 50 is disposed within the second cavity 202 and located on the vertical side of the atomizing component 30, both the power supply component 50 and the atomizing component 30 are horizontally offset to the left side of the first cavity 201. The center of gravity of the aerosol generating device as a whole is biased towards the side closer to the second cavity 202 (left side), thereby further increasing the difficulty of placing the aerosol generating device vertically or tilting it to the right.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments, the side surfaces further include a third side surface 223 and a fourth side surface 224 disposed opposite to each other. The third side surface 223 is connected between the first side surface 221 and the second side surface 222, and the fourth side surface 224 is also connected between the first side surface 221 and the second side surface 222. The third side surface 223 and the fourth side surface 224 may be disposed relatively parallel to each other. (See reference...) Figures 1 to 4 The orientations are as follows: the first side 221 is the right side of the outer shell 20, the second side 222 is the left side of the outer shell 20, the third side 223 is the front side of the outer shell 20, and the fourth side 224 is the rear side of the outer shell 20.

[0046] like Figure 5 and Figure 8 As shown, in some embodiments, the side surface includes a first end 22A connected to the bottom surface 21 and a second end 22B away from the bottom surface 21. That is, the first side surface 221, the second side surface 222, the third side surface 223, and the fourth side surface 224 each have the first end 22A and the second end 22B. The second end 22B is used to contact the placement surface 40 where the aerosol generating device is located in its natural resting state. In the natural resting state of the aerosol generating device, the height of the first end 22A relative to the placement surface 40 is greater than the height of the second end 22B relative to the placement surface 40. In other words, in the natural resting state of the aerosol generating device, the first end 22A and the placement surface 40 are spaced apart, and the second end 22B is in contact with the placement surface 40. Figure 5 and Figure 6In the illustrated embodiment, the first end 22A of the third side surface 223 is spaced apart from the placement surface 40, and the second end 22B of the third side surface 223 is in contact with the placement surface 40. That is, the height H1 of the first end 22A relative to the placement surface 40 is greater than the height H2 of the second end 22B relative to the placement surface 40. Specifically, H2 can be equal to 0, while H1 > H2. Thus, as... Figure 6 As shown, when the aerosol generating device is tilted, the side of the outer casing 20 is tilted at a certain angle relative to the placement surface 40, so that the liquid storage bottle 10 has a certain tilt relative to the placement surface 40. The bottom of the liquid storage bottle 10 is higher than its mouth, which can increase the liquid injection volume / injection rate and make the liquid flow smoother. However, in some other embodiments, H1 = H2 = 0, that is, the second side 222, the third side 223 or the fourth side 224 directly contact the placement surface 40, and the aerosol generating device is placed flat. When there is enough liquid in the liquid storage bottle 10, the liquid storage bottle 10 can also replenish the liquid storage chamber in the second cavity 202 through the liquid inlet 204.

[0047] In some embodiments, to create a height difference between the first end 22A and the second end 22B of the side surface, a protrusion 23 is provided at at least one location on the side surface other than the first side surface 221. That is, the protrusion 23 can be provided on one of the second side surface 222, the third side surface 223, and the fourth side surface 224; or, the protrusion 23 can be provided on two of the second side surface 222, the third side surface 223, and the fourth side surface 224; or, the protrusion 23 can be provided on all three of the second side surface 222, the third side surface 223, and the fourth side surface 224. The distance between the protrusion 23 and the first end 22A is less than the distance between the protrusion 23 and the second end 22B. That is, the protrusion 23 is located close to the bottom surface 21. The protrusion 23 is used to contact the placement surface 40 where the aerosol generating device is located in its natural resting state. In the natural resting state, the second end 22B of the side surface and the protrusion 23 are in contact with the placement surface 40, respectively. Figure 5 and Figure 6 In the illustrated embodiment, both the third side 223 and the fourth side 224 are provided with protrusions 23. Therefore, when the aerosol generating device is tilted relative to the placement surface 40 in a tilted state, the liquid storage bottle 10 has a certain degree of inclination relative to the placement surface 40, resulting in smoother liquid flow.

[0048] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent.
