AI Technical Summary
In existing aerosol generating devices, the atomizing component can still operate even when the liquid channel between the liquid reservoir and the atomizing component is closed, leading to the depletion of the liquid matrix and the generation of high-temperature aerosol components, which poses a safety risk.
An aerosol generating device was designed, wherein the liquid flow channel between the liquid reservoir and the main body of the device can be switched between different positions. When it is in the first position, the channel is closed to prevent negative pressure from being transmitted to the airflow sensor and to ensure liquid supply. When it is in the second position, the channel is open to achieve airtight connection and ensure liquid supply and atomization component operation.
This effectively avoids dry burning of the atomizing components due to liquid depletion, reduces safety risks, and ensures the safety and stability of the aerosol generation device.

Abstract
Description
Technical Field
[0001] This application relates to the field of aerosol generation technology, and particularly to aerosol generation apparatus. Background Technology
[0002] The prior art provides a typical aerosol generating device, which includes a separate liquid reservoir and a device body. The liquid reservoir is used to store a certain volume of liquid matrix, and the device body is provided with an atomizing component for receiving the liquid matrix and evaporating the liquid matrix by heating.
[0003] In some designs, the liquid reservoir and the main body of the device typically establish liquid communication through a liquid guide column with a liquid guide hole. The first housing of the liquid reservoir has a first protrusion, and the second housing of the main body of the device has a guide groove and a limiting groove. After the liquid reservoir is installed on the main body of the device, the user can rotate the first housing of the liquid reservoir and the second housing of the main body relative to each other to open or close the liquid outlet of the liquid reservoir. However, when the liquid outlet is closed, the user can still trigger the airflow sensor when drawing air, thereby activating the atomizing component. In this case, there is a risk that the liquid matrix in the second liquid reservoir chamber will be depleted, which may cause the atomizing component to overheat due to insufficient liquid supply, thereby generating aerosol components that pose a safety risk.
[0004] Application content
[0005] To address the issue that when the liquid channel between the liquid reservoir and the atomizing component in an aerosol generator is closed, the atomizing component can still operate, potentially leading to the generation of aerosol components that pose a safety risk.
[0006] One embodiment of this application provides an aerosol generating apparatus, including an apparatus body and a reservoir for replenishing the apparatus body with a liquid matrix.
[0007] The liquid reservoir includes:
[0008] A first housing, wherein a first liquid storage chamber for storing a liquid matrix is defined within the first housing;
[0009] The suction nozzle is disposed on or is part of the first housing;
[0010] A first air tube is disposed within the first housing and defines a first air passage communicating with the mouthpiece, the end of the first air tube opposite to the mouthpiece having a first opening;
[0011] The main body of the device includes:
[0012] The second housing has a second liquid storage chamber defined therein for storing a liquid matrix;
[0013] An atomizing component, disposed within the second housing, is used to atomize a liquid matrix originating from the second liquid storage chamber to generate an aerosol;
[0014] A second air tube is disposed within the second housing and defines a second air passage, the second air passage having a second opening that can mate with the first opening;
[0015] An airflow sensor, connected to the second airway, is used to sense changes in airflow within the second airway;
[0016] The reservoir is configured to connect to the main body of the device, thereby establishing a flow channel between them to provide the liquid matrix in the first reservoir to the second reservoir.
[0017] When the reservoir is connected to the main body of the device, the reservoir can move from a first position to a second position relative to the main body of the device. When the reservoir is in the first position, the liquid flow channel is closed, and the first opening and the second opening remain disconnected, thereby limiting the transfer of suction negative pressure in the first air passage to the second air passage and triggering the airflow sensor. When the reservoir is in the second position, the liquid flow channel is opened, and the first opening and the second opening remain airtightly connected.
[0018] One embodiment of this application provides an aerosol generating device. When the reservoir is in a first position, there is an air cavity between the reservoir and the device body. The air cavity is connected to the first air passage. When the nozzle is suctioned, the air in the air cavity can replenish the first air passage.
[0019] One embodiment of this application provides an aerosol generating device, the main body of which includes a second support, the second support being disposed within a second housing, and the second support having a liquid inlet channel communicating with a second liquid storage chamber.
[0020] One embodiment of this application provides an aerosol generating device, the main body of which further includes a first sealing member disposed on a second support. The first sealing member has a first through hole, which communicates with the liquid inlet channel.
[0021] One embodiment of this application provides an aerosol generating device, wherein the liquid reservoir further includes a first support installed in the first housing, the first support including a liquid guide column extending away from the first liquid storage cavity, the liquid guide column being hollow and having at least one liquid guide hole thereon.
[0022] One embodiment of this application provides an aerosol generating device, wherein when the liquid reservoir is in a first position, the liquid guide hole is located in the first through hole or the liquid inlet channel; and when the liquid reservoir is in a second position, the liquid guide hole is located in the second liquid storage chamber.
[0023] One embodiment of this application provides an aerosol generating device, wherein the first bracket includes a second protrusion extending from the first bracket to the second bracket, and the second bracket is provided with a clearance portion, and the first bracket and the second bracket are positioned during the installation process through the second protrusion and the clearance portion.
[0024] One embodiment of this application provides an aerosol generating device, wherein the liquid reservoir further includes a liquid output component having an outlet for discharging a liquid matrix from a first liquid reservoir. The liquid output component is rotatable relative to the first support between a third position and a fourth position. When the liquid output component is in the third position, the outlet is in communication with the liquid guide hole. When the liquid output component is in the fourth position, the outlet is blocked and closed, thereby preventing the first liquid reservoir from discharging the liquid matrix into the liquid guide hole.
[0025] One embodiment of this application provides an aerosol generating device, wherein the liquid reservoir includes a second seal, and the second seal has a raised rib on the side facing the liquid guide column, the raised rib defining a limiting groove for the liquid output component in the rotation path.
[0026] One embodiment of this application provides an aerosol generating device, wherein the first housing has a first snap-fit portion, the liquid output component has a second snap-fit portion, and the first housing and the liquid output component are connected through the first snap-fit portion and the second snap-fit portion.
[0027] One embodiment of this application provides an aerosol generating device, wherein the liquid output component includes a first sliding portion, the first support includes a second sliding portion, and the liquid output component and the first support are rotatably connected through the first sliding portion and the second sliding portion.
[0028] One embodiment of this application provides an aerosol generating apparatus, wherein the reservoir is configured to be operable to rotate relative to the apparatus body and to move longitudinally from a first position to a second position along a predetermined trajectory path.
[0029] One embodiment of this application provides an aerosol generating device, wherein the first housing includes a first protrusion, and the second housing defines a guide groove and a limiting groove. The first protrusion is slidably disposed in the guide groove and the limiting groove. The guide groove defines a portion of the path from the first housing to the second housing, and the limiting groove defines the path from the first support to the second position.
[0030] One embodiment of this application provides an aerosol generating apparatus, wherein the guide groove extends along the axial direction of the apparatus body.
[0031] One embodiment of this application provides an aerosol generating device, wherein the limiting groove is configured as an inclined groove or an arc-shaped groove that deviates from the axial direction of the main body of the device.
[0032] One embodiment of this application provides an aerosol generating apparatus, wherein a liquid storage element for absorbing and retaining a liquid matrix is provided in the second liquid storage chamber.
[0033] One embodiment of this application provides an aerosol generating device, wherein the inner wall of the first air pipe is provided with a first groove; and / or the inner wall of the second air pipe is provided with a second groove.
[0034] One embodiment of this application provides an aerosol generating device, wherein the liquid reservoir includes a second sealing member disposed in the mounting groove of the liquid output member, the second sealing member having a third through hole communicating with the first gas pipe, and the inner sidewall of the third through hole having a third groove communicating with the first groove.
[0035] The liquid reservoir and main body of the aerosol generating device of this application, when the liquid reservoir 1 is in the first position, the liquid flow channel is closed, and the first opening and the second opening are kept disconnected. When the user draws in, the negative pressure cannot be transmitted to the second airway and thus trigger the airflow sensor. This avoids the atomizing component from depleting the liquid matrix in the second liquid reservoir and causing dry burning, thereby generating aerosol components that pose a safety risk.

[0077] One embodiment of this application provides an aerosol generating device 10, such as... Figure 1-4 As shown, it includes a device body 2 and a reservoir 1 for replenishing the device body 2 with liquid matrix.
[0078] The reservoir 1 includes a first housing 11, a nozzle 17, and a first air tube 13. The first housing 11 defines a first reservoir chamber 111 for storing a liquid matrix. The nozzle 17 is disposed in or is part of the first housing 11. The first air tube 13 is disposed in the first housing 11 and defines a first air passage 131 communicating with the nozzle, and the end of the first air tube 13 opposite to the nozzle 17 has a first opening 132.
[0079] The main body 2 of the device includes a second housing 21, an atomizing assembly 25, a second air tube 23, and an airflow sensor 27. The second housing 21 defines a second liquid storage chamber 211 for storing a liquid matrix. The atomizing assembly 25 is disposed within the second housing 21 and is used to atomize the liquid matrix originating from the second liquid storage chamber 211 to generate an aerosol. The second air tube 23 is disposed within the second housing 21 and defines a second air passage 231, which has a second opening 232 that can mate with a first opening 132. The airflow sensor 27 communicates with the second air passage 231 and is used to sense changes in airflow within the second air passage 231.
[0080] The reservoir 1 is configured to connect to the device body 2, thereby establishing a liquid flow channel 101 between them to supply the liquid matrix in the first reservoir 111 to the second reservoir 211. While the reservoir 1 is connected to the device body 2, the reservoir 1 can move relative to the device body 2 from a first position to a second position. When the reservoir 1 is in the first position, the liquid flow channel 101 is closed, and the first opening 132 and the second opening 232 remain disconnected, thereby limiting the transfer of suction negative pressure in the first air passage 131 to the second air passage 231, which in turn triggers the airflow sensor 27. When the reservoir 1 is in the second position, the liquid flow channel 101 is opened, and the first opening 132 and the second opening 232 remain airtightly connected.
[0081] In the aerosol generating device 10 of this application, when the liquid reservoir 1 is in the first position, the liquid flow channel 101 is closed, and the first opening 132 and the second opening 232 remain disconnected. When the user inhales, the negative pressure cannot be transmitted to the second airway 231 to trigger the airflow sensor 27, thus preventing the atomizing component 25 from depleting the liquid matrix in the second liquid reservoir 211 and causing dry burning, thereby generating aerosol components that pose a safety risk.
[0082] In one embodiment of this application, the liquid reservoir 1 includes a suction nozzle 17, which can be held in the mouth by a user. The first housing 11, the suction nozzle 17, and the air tube 13 are integrally formed. In another embodiment of this application, the liquid reservoir 1 further includes a suction nozzle 17, which can be held in the mouth by a user. The first housing 11, the suction nozzle 17, and the air tube 13 are connected by assembly.
[0083] In one embodiment of this application, the liquid matrix may comprise a liquid containing tobacco-containing substances with volatile tobacco aroma components, or it may be a liquid containing non-tobacco substances. The liquid matrix may comprise water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include areca nut extract, menthol, peppermint, spearmint oil, various fruit flavoring components, etc., but are not limited thereto. Flavorings contain ingredients that can provide the user with various fragrances or flavors. Vitamin mixtures may be mixtures containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited thereto. Based on the different properties of the liquid matrix, aerosol matrix reservoirs can be used in different fields, such as medical applications and electronic aerosol atomization.
[0084] In one embodiment of this application, when the reservoir 1 is in the first position, there is an air cavity 102 between the reservoir 1 and the device body 2. The air cavity 102 is connected to the first air passage 131 and can communicate with the outside air. When the suction nozzle 17 is applied to the suction, the air in the air cavity 102 can be replenished to the first air passage 131.
[0085] In one embodiment of this application, the first air tube 13 and the second air tube 23 may have a first through hole and a second through hole, respectively. When the liquid storage chamber 1 is in the first position, the first through hole and the second through hole are connected, and air in the air chamber 102 can enter the first air passage 131, thereby limiting the suction negative pressure in the first air passage 131 from being transmitted to the second air passage 231 and triggering the airflow sensor 27. When the liquid storage chamber 1 is in the second position, the first through hole and the second through hole are staggered, and the first air passage 131 and the second air passage 231 are connected, and the suction negative pressure in the first air passage 131 can be transmitted to the second air passage 231 and trigger the airflow sensor 27.
[0086] In one embodiment of this application, the liquid reservoir 1 includes a first support 12 installed within a first housing 11. The first housing 11 and the first support 12 define a first liquid storage cavity 111 for storing a liquid matrix. The first support 12 includes a liquid guide column 121 extending away from the first liquid storage cavity 111. The liquid guide column 121 is hollow and has at least one liquid guide hole 122 thereon. In one embodiment of this application, the hollow liquid guide column 121 and the liquid guide hole 122 constitute a liquid flow channel 101 for supplying the liquid matrix in the first liquid storage cavity 111 to the second liquid storage cavity 211.
[0087] In one embodiment of this application, the device body 2 includes a second support 22 disposed within a second housing 21. The second support 22 has a liquid inlet channel 221 communicating with a second liquid storage chamber 211, and a liquid guide column 121 can extend into the liquid inlet channel 221. In one embodiment of this application, the second support 22 defines the second liquid storage chamber 211.
[0088] In one embodiment of this application, the liquid reservoir 1 includes a first support 12, and the device body 2 includes a second support 22. The second support 22 is provided with a liquid guiding column and a liquid guiding hole. The hollow liquid guiding column and the liquid guiding hole constitute a liquid flow channel 101 for providing the liquid matrix in the first liquid reservoir 111 to the second liquid reservoir 211.
[0089] In one embodiment of this application, the second support 22 and the second air tube 23 can be integrally formed. In another embodiment of this application, the second air tube 23 is inserted into the second support 22.
[0090] In one embodiment of this application, the device body 2 includes a first sealing member 24, which is disposed on the second bracket 22, such as... Figure 5 As shown, the first sealing member 24 has a first through hole 241, and the second bracket 22 has a liquid inlet channel 221, with the first through hole 241 and the liquid inlet channel 221 communicating. In one embodiment of this application, the first sealing member 24 has a fourth through hole 242, through which the second air tube 23 passes.
[0091] In one embodiment of this application, when the liquid reservoir 1 is in the first position, the liquid guide hole 122 is located in the first through hole 241 or the liquid inlet channel 221, so that the liquid matrix in the first liquid reservoir 111 cannot enter the second liquid reservoir 211; when the liquid reservoir 1 is in the second position, the liquid guide hole 122 is located in the second liquid reservoir 211, so that the liquid matrix in the first liquid reservoir 111 can enter the second liquid reservoir 211.
[0092] In one embodiment of this application, the number of liquid guiding columns 121 can be multiple, and the number of liquid guiding holes 122 corresponds to the number of liquid guiding columns 121. In one embodiment of this application, two liquid guiding holes 122 are formed on one liquid guiding column 121, and the two liquid guiding holes 122 on one liquid guiding column 121 are arranged opposite to each other. In one embodiment of this application, the number of liquid guiding columns 121 is two. When the liquid matrix in the liquid guiding hole 122 of one liquid guiding column 121 enters the second liquid storage chamber 211 from the first liquid storage chamber 111, the air pressure in the first liquid storage chamber 111 decreases. At this time, the air in the second liquid storage chamber 211 can enter the first liquid storage chamber 211 through the liquid guiding hole 122 of the other liquid guiding column 121, thereby preventing the liquid matrix in the first liquid storage chamber 111 from being unable to enter the second liquid storage chamber 211 due to the decrease in air pressure.
[0093] In one embodiment of this application, a liquid guiding hole 122 is disposed on the sidewall of the liquid guiding column 121. In another embodiment of this application, the diameter of the liquid guiding hole 122 is smaller than the inner diameter of the hollow portion of the liquid guiding column 121. The smaller diameter of the liquid guiding hole 122 relative to the inner diameter of the hollow portion of the liquid guiding column 121 results in a slower outflow rate of the liquid matrix from the hollow portion of the liquid guiding column 121, thereby preventing leakage of the liquid matrix from the atomizing assembly 25 after excessive liquid matrix is retained in the liquid storage component 215 of the second liquid storage chamber 211.
[0094] In one embodiment of this application, the aperture or diameter of the liquid guiding hole 122 is 0.5mm-1.5mm. In one embodiment of this application, the liquid guiding hole 122 is circular, elongated, or other shaped opening, and the diameter of the liquid guiding hole 122 is 0.5mm-1.5mm, so that the liquid guiding hole 122 has a capillary effect. When the aerosol generating device 10 is drawn in by the user, the air pressure in the second liquid storage chamber 211 decreases, while the air pressure in the first liquid storage chamber 111 remains unchanged, so that the liquid matrix in the first liquid storage chamber 111 enters the second liquid storage chamber 211 through the liquid guiding column 121. When the aerosol generating device 10 is not in working state, the air pressure in the first liquid storage chamber 111 and the second liquid storage chamber 211 remains balanced. The liquid guiding hole 122 has a certain capillary effect on the liquid matrix therein, and the liquid matrix is retained in the liquid guiding hole 122, thus preventing the liquid matrix from continuously entering the second liquid storage chamber 211 when the aerosol generating device 10 is not working, thereby preventing the liquid matrix from leaking through the atomizing component 25. In one embodiment of this application, the aperture or diameter of the liquid guiding hole 122 can be 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm or 1.5 mm.
[0095] In one embodiment of this application, when the liquid reservoir 1 is in the first position, the liquid guide hole 122 is located in the liquid inlet channel 221, and the liquid guide column 121 abuts against the liquid storage component 215. In another embodiment of this application, when the liquid reservoir 1 is in the first position, the liquid guide hole 122 is located in the liquid inlet channel, and the liquid guide column 121 and the liquid storage component 215 have a certain gap, which is 0.5mm-1.5mm, allowing capillary action between the liquid guide component 121 and the liquid storage component to maintain a certain amount of liquid matrix. In another embodiment of this application, when the liquid reservoir 1 is in the first position, the liquid guide hole 122 is located in the second liquid storage chamber 211, and the liquid guide column 121 is inserted into the liquid storage component 215.
[0096] In one embodiment of this application, the end of the liquid guiding column 121 is tapered, and the first through hole 241 of the first seal 24 includes a sealing film, which is tapered, and the liquid guiding column 121 can puncture the sealing film.
[0097] In one embodiment of this application, the outer wall of the liquid guiding column 121 and the inner wall of the liquid flow channel 221 maintain a distance between 0.1 mm and 1.0 mm. At this time, there is also a capillary effect between the outer wall of the liquid guide column 121 and the inner wall of the liquid flow channel 221. When the aerosol generating device 10 is drawn by the user, the air pressure in the second liquid storage chamber 211 decreases, while the air pressure in the first liquid storage chamber 111 remains unchanged, so that the liquid matrix in the first liquid storage chamber 111 enters the second liquid storage chamber 211 through the liquid guide column 121. When the aerosol generating device 10 is not in working condition, the air pressure in the first liquid storage chamber 111 and the second liquid storage chamber 211 remains balanced. The outer wall of the liquid guide column 121 and the inner wall of the liquid flow channel 221 have a certain capillary effect on the liquid matrix therein. The liquid matrix is held between the outer wall of the liquid guide column 121 and the inner wall of the liquid flow channel 221, which avoids the liquid matrix from continuously entering the second liquid storage chamber 211 when the aerosol generating device 10 is not working, thereby preventing the liquid matrix from leaking through the atomizing component 25. In one embodiment of this application, the distance between the outer wall of the liquid guiding column 121 and the inner wall of the liquid flow channel 221 can be 0.1 mm, 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, or 1.0 mm.
[0098] In one embodiment of this application, such as Figure 1 As shown, the first seal 24 is located on the side of the second bracket 22 facing the liquid reservoir 1. When the liquid reservoir 1 is installed on the main body 2 of the device, the liquid guide column 121 of the first bracket 12 is first inserted into the first through hole of the first seal 24, and then inserted into the liquid inlet channel 221 of the second bracket 22.
[0099] In one embodiment of this application, the liquid reservoir 1 includes a liquid output component 14, such as... Figure 7-8 As shown, the liquid output component 14 has an outlet 141 for discharging liquid matrix from the first liquid storage chamber 111. The liquid output component 14 can rotate relative to the first support 12 between a third position and a fourth position. When the liquid output component 14 is in the third position, the outlet 141 is open, thereby communicating with the liquid guide hole 122. When the liquid output component 14 is in the fourth position, the outlet 141 is blocked and closed, thereby preventing the first liquid storage chamber 111 from discharging liquid matrix into the second liquid storage chamber 211. The liquid reservoir 1 can be operatively connected to the device body 2 from a separated state. After the liquid reservoir 1 is connected to the device body 2, the device body 2 can drive the liquid output component 14 to rotate. The liquid output component 14 remains connected to the device body 2 and cannot be separated, thereby allowing the user to open and close the outlet 141 according to usage, thereby preventing liquid matrix leakage.

In another embodiment of this application, the rib 152 includes an annular second rib, and the first rib 1521 and the second rib are located at both ends of the limiting groove 153. When the liquid output component 14 is in the fourth position, the liquid outlet 141 is blocked, and the second rib is located between the second seal 15 and the liquid inlet channel 221 to prevent leakage of the liquid matrix in the liquid inlet channel 221.

The first protrusion 114 is slidably disposed in the guide groove 212 and the limiting groove 213. The guide groove 213 defines a portion of the path from the first housing 11 to the second housing 21, and the limiting groove 213 defines the path from the liquid reservoir 1 to the second position.
[0106] In one embodiment of this application, the movement of the reservoir 1 and the device body 2 between a first position and a second position includes only the linear displacement of the reservoir 1 relative to the device body 2 in the axial direction. For example, when the reservoir 1 is in the first position, there is a gap between the first housing and the second housing on their outer surfaces, and the two liquid guide columns in the reservoir 1 are located inside the seal of the device body 2 or surrounded by the seal by the liquid guide holes on the liquid guide columns, while the first opening of the first air pipe and the second opening of the second air pipe are disconnected to form a gap. When the reservoir 1 is linearly moved to the second position, the liquid guide holes on the liquid guide columns pass through the seal and enter the second reservoir cavity, while the first opening of the first air pipe moves downward, thereby forming an airtight connection with the second opening of the second air pipe. In another embodiment of this application, the movement of the reservoir 1 and the device body 2 between the first position and the second position includes only the rotation of the reservoir 1 relative to the device body 2 in the circumferential direction; for example, there is a notch or groove between the first air pipe and the second air pipe that can constitute a non-airtight connection in a certain rotational position.
[0107] In another embodiment of this application, the movement of the reservoir 1 and the device body 2 between the first and second positions simultaneously includes rotation of the reservoir 1 relative to the device body 2 in the circumferential direction and displacement in the longitudinal direction.

The first housing 11 is first installed to the second housing 21 along the axial direction of the aerosol generating device 10. In one embodiment of this application, the first housing 11 is spirally installed to the second housing 21 relative to the second housing 21 along the axial direction of the aerosol generating device 10; that is, during the installation of the first housing 11 to the second housing 21, there is both circumferential displacement and axial displacement.
[0108] In one embodiment of this application, the first protrusion 114 is circular, which makes the process of installing the first housing 11 onto the second housing 21 smoother.

A portion of the liquid matrix entering the second liquid storage cavity 211 from the first liquid storage cavity 111 is absorbed by the liquid storage component 215, while the remaining portion is distributed in the unfilled space of the second liquid storage cavity 211. The liquid matrix in the second liquid storage chamber 211 is received or retained by the liquid storage component 215 in whole or in part, so that the liquid matrix in the second liquid storage chamber 211 is not easy to leak through the atomizing component 25 during the transportation or standing of the aerosol generating device 10; and the user can obtain a better taste in the initial stage of inhalation when using the aerosol generating device 10.
