Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aerosol generating device, in particular to an atomization device. BACKGROUND

[0002] The atomization device is an apparatus that can heat liquid aerosol substrate to generate aerosol. Affected by changes in the environment in which the atomization device is located, the liquid aerosol substrate stored in the liquid storage cavity of the atomization device is at risk of leaking from the liquid storage cavity. For example, when the ambient temperature in which the aerosol substrate is located increases, the liquid aerosol substrate expands, causing the pressure in the liquid storage cavity to increase, thereby causing the aerosol substrate to leak. For another example, when the atomization device is left stationary for a long time with the liquid guide hole facing downward, the aerosol substrate is at risk of leaking due to the effect of gravity. For yet another example, during long-distance transportation, the aerosol substrate shakes in the atomization device, the temperature of the aerosol substrate increases and the aerosol substrate expands, causing the pressure in the liquid storage cavity to increase, thereby causing the aerosol substrate to leak. Therefore, an atomization device capable of plugging the liquid guide hole has emerged.

[0067] Referring to Figures 1-5 As shown in the drawings for describing the embodiments of the present application, the present application provides an atomization device 100, which comprises a housing assembly, an atomization assembly, and an adjusting assembly 30. The atomization assembly is arranged in the housing assembly, and the adjusting assembly 30 is arranged on the housing assembly, and the adjusting assembly 30 is used to adjust the flow of aerosol substrate accommodated in the housing assembly to the atomization assembly.

[0068] Further, the housing assembly is configured with a liquid storage cavity 14, a liquid guide hole 131, and an adjusting hole 1121. The liquid storage cavity 14 and the liquid guide hole 131 are respectively arranged in the housing assembly, and the liquid guide hole 131 communicates with the liquid storage cavity 14 to form a liquid path for supplying aerosol substrate to the atomization assembly.

[0069] The atomization assembly is arranged in the housing assembly and is used to heat the aerosol substrate under the condition of being powered on, so that the heated aerosol substrate is atomized to generate aerosol.

[0070] Further, the adjusting assembly 30 comprises a blocking piece 31 and an adjusting piece 32. The adjusting piece 32 is used to adjust the blocking piece 31 to block the liquid guide hole 131 or to guide the liquid guide hole 131.

[0071] Referring to Figures 2-3 As shown in the drawings for describing the embodiments of the present application, the present application provides an atomization device 100, which comprises a housing assembly, an atomization assembly, and an adjusting assembly 30. The atomization assembly is arranged in the housing assembly, and the adjusting assembly 30 is arranged on the housing assembly, and the adjusting assembly 30 is used to adjust the flow of aerosol substrate accommodated in the housing assembly to the atomization assembly.

[0072] Furthermore, when the adjusting member 32 is in the first position, the sealing member 31 is in the sealing position and seals the liquid guiding hole 131. At this time, the aerosol matrix contained in the liquid storage chamber 14 cannot flow to the atomizing component through the liquid guiding hole 131, thereby preventing the liquid guiding cotton 24 in the atomizing component from leaking due to the large pressure from the aerosol matrix.

[0073] When the adjusting member 32 is in the second position, the sealing member 31 is in the conducting position, and the aerosol matrix contained in the liquid storage chamber 14 flows to the atomizing component through the liquid guiding hole 131.

[0074] Furthermore, please refer to Figure 2 As shown, by controlling the adjustment part 321 to be exposed in the adjustment hole 1121, the current position of the adjustment member 32 can be intuitively determined by the step. The current position of the sealing member 31 can also be determined based on the current position of the adjustment member 32, thereby determining whether the liquid guiding hole 131 is currently in a blocked state or a conductive state. That is, the liquid guiding hole 131 can be intuitively determined based on the position of the adjustment member 32.

[0075] Further, the housing assembly includes a housing 11, a first support 12, and a first seal 13. The first support 12 and the first seal 13 are respectively disposed within the housing 11.

The first sealing member 13 is sealingly connected between the first support 12, the atomizing component, and the first shell 111, and the first sealing member 13, together with the first support 12, the atomizing component, and the first shell 111, together form the liquid storage cavity 14.

[0078] Further, the atomization assembly comprises an outer tube 21, an inner tube 22, filler cotton 23, liquid guiding cotton 24 and a heating element 25. The outer tube 21 is sealingly inserted between the first support 12 and the suction nozzle 1111. The inner tube 22 is coaxially arranged in the outer tube 21, and the filler cotton 23 is filled between the outer tube 21 and the inner tube 22. The liquid guiding cotton 24 and the heating element 25 are arranged in the inner tube 22 respectively, and the liquid guiding cotton 24 is arranged between the heating element 25 and the inner wall of the inner tube 22.

[0079] The outer tube 21 is provided with a first liquid passing hole 211, and the inner tube 22 is provided with a second liquid passing hole 221. Aerosol substrate enters the liquid guiding cotton 24 through the first liquid passing hole 211, the filler cotton 23 and the second liquid passing hole 221 in sequence, and is atomized by the heating element 25 to form aerosol.

[0080] Further, as shown in Figure 5 The adjusting assembly 30 further comprises a connecting piece 33 connected between the blocking piece 31 and the adjusting piece 32. The adjusting piece 32 drives the blocking piece 31 to move between the blocking position and the conducting position by driving the connecting piece 33.

[0081] Further, the blocking piece 31 is located on the central axis 331 of the connecting piece 33. The adjusting piece 32 drives the connecting piece 33 to rotate along the central axis 331 by moving linearly between the first position and the second position. The connecting piece 33 rotates and synchronously drives the blocking piece 31 to move along the length direction of the central axis 331 between the blocking position and the conducting position.

[0082] Further, the adjusting piece 32 drives the connecting piece 33 to rotate along the central axis 331 by moving linearly under the action of external force.

[0084] Further, the first connecting part 312 is screw-connected with the second connecting part 332. The adjusting part 32 moves along a straight line between the first position and the second position under the action of an external force and the limiting of the adjusting hole 1121, so that the driving part 322 drives the third connecting part 333 to drive the connecting part 33 to rotate along the central axis 331 synchronously, the second connecting part 332 drives the first connecting part 312 to drive the blocking part 31 to move along the central axis 331 synchronously, so that the blocking part 311 blocks the liquid guide hole 131 or guides the liquid guide hole 131.

[0085] In an embodiment, the first connecting part 312 is screw-connected with the second connecting part 332, so that when the connecting part 33 rotates along the central axis 331, the blocking part 31 moves along the central axis 331 between the blocking position and the guiding position synchronously.

Wherein, the connecting part 33 rotates along the central axis 331 to change the position of the guide column 3121 in the screw groove 3321, so that the blocking part 31 moves along the central axis 331 between the blocking position and the guiding position.

[0087] Further, in an embodiment, the first connecting part 312 is configured to have the connecting hole 3122 with an opening facing the second connecting part 332, the hole wall of the connecting hole 3122 has two guide columns 3121 oppositely arranged, and the two guide columns 3121 respectively extend along the radial central axis 331, and the outer wall of the second connecting part 332 is configured to have one screw groove 3321 corresponding to each guide column 3121.

[0088] In another embodiment, the first connecting portion 312 is configured with a connecting hole 3122 having an opening facing the second connecting portion 332, a hole wall of the connecting hole 3122 is provided with two helical grooves 3321 symmetrical along the central axis 331, the two helical grooves 3321 respectively extend along the direction of the central axis 331, and an outer wall of the second connecting portion 332 is configured with a guide column 3121 corresponding to each helical groove 3321, and the two guide columns 3121 respectively extend radially outward into the respective corresponding helical groove 3321.

[0089] Further, as shown in Figure 7 and Figure 9 , the first support 12 is configured with a guide hole 121, and the first connecting portion 312 is arranged in the guide hole 121, so that the blocking member 31 moves along the central axis 331 under the limiting of the guide hole 121.

[0090] Preferably, the outer wall of the first connecting portion 312 is provided with at least one guide portion 3123 extending along the direction of the central axis 331, and the first support 12 is provided with a guide groove 122 matched with the guide portion 3123. The guide groove 122 at least partially communicates with the guide hole 121. Among them, the guide portion 3123 is limited in the guide groove 122, and at least one guide portion 3123 slides in the corresponding guide groove 122 when the blocking member 31 moves along the central axis 331.

[0091] By setting the guide groove 122 and the guide portion 3123 to limit each other, the circumferential rotation of the blocking member 31 during the movement along the length direction of the central axis 331 can be avoided.

[0092] Further, as shown in Figure 2 and Figure 10 , the housing assembly further comprises a second support 15.

[0093] Please refer to Figure 2 , Figure 5 and Figure 8As shown, the connecting piece 33 further comprises a fourth connecting portion 334 and a limiting stop portion 335. The fourth connecting portion 334 is connected between the second connecting portion 332 and the third connecting portion 333 along the central axis 331 and penetrates the limiting hole 151. The limiting stop portion 335 is located on the outer wall of the connection between the fourth connecting portion 334 and the second connecting portion 332 and abuts against the side of the limiting hole 151 close to the liquid guide hole 131.

[0094] By limiting the connecting piece 33 through the limiting hole 151, the connecting piece 33 can rotate more stably along the central axis 331. In the state of screw connection between the first connecting portion 312 and the second connecting portion 332, the limiting hole 151 and the limiting stop portion 335 can effectively limit the influence of the reaction force of the blocking piece 31 on the connecting piece 33 on the connection between the third connecting portion 333 and the driving portion 322. Thus, the connecting piece 33 can be driven by the adjusting piece 32 to move the blocking piece 31 along the central axis 331 stably.

[0095] Further, the third connecting portion 333 and the driving portion 322 are engagedly connected. In an embodiment, the third connecting portion 333 is in the form of a gear and the driving portion 322 is in the form of a rack.

[0096] Further, the atomization assembly and the shell assembly are jointly configured to form an airflow channel. Specifically, the inner tube 22, the suction nozzle 1111, the first support 12, and the second support 15 jointly configure the airflow channel.

[0097] Further, as shown in Figures 5-6 As shown, the adjusting piece 32 further comprises a connecting plate portion 323. The driving portion 322 and the adjusting portion 321 are connected with the connecting plate portion 323 respectively. The connecting plate portion 323 has an air inlet hole for communicating the airflow channel.

[0098] Further, as shown in Figure 2 As shown, when the adjusting piece 32 is located at the first position, the connecting plate portion 323 blocks the air inlet end 171 of the airflow channel so that the airflow channel cannot pass through the airflow. At the same time, the blocking piece 31 is located at the blocking position and blocks the liquid guide hole 131 so that the aerosol substrate in the liquid storage cavity 14 cannot move to the atomization assembly. Thus, the blocking of the liquid guide hole 131 and the blocking of the airflow channel are simultaneously controlled by the adjusting piece 32.

[0099] As shown in Figure 3As shown, when the adjusting member 32 is in the second position, the air inlet hole communicates the adjusting hole 1121 with the air inlet end 171 of the airflow passage, so that the airflow passage can be used for airflow, while the blocking member 31 is in the open position and opens the liquid guide hole 131. Thus, the opening of the liquid guide hole 131 and the opening of the airflow passage are simultaneously controlled by the adjusting member 32.

[0100] Further, in an embodiment, when the blocking member 31 is in the blocking position, the blocking part 311 is located in the liquid guide hole 131, and when the blocking member 31 is in the open position, the blocking part 311 extends out of the liquid guide hole 131 away from the liquid storage cavity 14.

[0101] Preferably, referring to Figure 3 As shown, in another embodiment, the liquid storage cavity 14 contains a liquid storage cotton 141. When the blocking member 31 is in the open position, the blocking part 311 penetrates through the liquid guide hole 131 and extends into the liquid storage cavity 14 to press the liquid storage cotton 141, so that the liquid guide cotton 24 releases the stored aerosol substrate more quickly under the extrusion of the blocking part 311, so that the released aerosol substrate quickly flows to the atomization assembly through the liquid guide hole 131, thereby improving the supply speed of the aerosol.

[0102] Further, referring to Figures 11-14 As shown, the open position includes a first sub-open position and a second sub-open position. The second position includes a first sub-position and a second sub-position. The air inlet hole includes a first sub-air inlet hole 3231 and a second sub-air inlet hole 3232, and the aperture of the second sub-air inlet hole 3232 is larger than the aperture of the first sub-air inlet hole 3231.

[0103] When the adjusting member 32 is in the first sub-position, the first sub-air inlet hole 3231 communicates the airflow passage with the adjusting hole 1121, and the blocking member 31 moves a first distance along the central axis 331 relative to the connecting member 33 and extends into the liquid storage cavity 14 to the first sub-open position.

[0104] When the adjusting member 32 is in the second sub-position, the second sub-air inlet hole 3232 communicates the airflow passage with the adjusting hole 1121, and the blocking member 31 moves a second distance along the central axis 331 relative to the connecting member 33 and extends into the liquid storage cavity 14 to the second sub-open position.

[0105] Further, the second distance is greater than the first distance. So that the degree of extrusion of the liquid storage cotton 141 by the blocking member 31 in the second sub-conductive position is greater than the degree of extrusion of the liquid storage cotton 141 by the blocking member 31 in the first sub-conductive position. Therefore, the liquid storage cotton 141 can be further extruded to release the latched aerosol substrate when the blocking member 31 is in the second sub-conductive position, so that the supply amount of aerosol substrate is greater.

[0106] Further, since the second sub-air inlet hole 3232 has a larger hole diameter than the first sub-air inlet hole 3231, the air flow through the second sub-air inlet hole 3232 into the airflow passage when the adjustment member 32 is in the second sub-position is greater than the air flow through the first sub-air inlet hole 3231 into the airflow passage when the adjustment member 32 is in the first sub-position, so that the supply amount of aerosol substrate is in direct proportion to the air flow when the adjustment member 32 is in different position states.

[0107] Further, as shown in Figures 3-4 and Figures 11-14 , the shell assembly further comprises a second seal 16 and a third seal 17. The second seal 16 is sealingly connected between the first support 12 and the second support 15, and the third seal 17 is provided between the second support 15 and the connecting plate portion 323. The airflow passage is formed by the combination of the mouthpiece 1111, the inner tube 22, the first support 12, the second seal 16, the second support 15, and the third seal 17, and the third seal 17 forms the air inlet end 171 of the airflow passage.

[0108] As shown in Figures 3-4 , when the adjustment member 32 is in the first position, the connecting plate portion 323 blocks the air inlet end 171, thereby achieving the blocking of the airflow passage.

[0109] Further, the shell assembly further comprises a base 18. The base 18 is provided in the outer shell 11 and cooperates with the outer shell 11 to form a mounting cavity 19. The adjustment member 32 is provided in the mounting cavity 19, and the base 18 and the first support 12 limit the second seal 16, the second support 15, and the third seal 17 between the first support 12 and the adjustment member 32 by mutual clamping connection.

[0110] Please continue to refer to Figures 3-4As shown, the atomization device 100 further comprises an electric control assembly, which comprises a circuit board 41 and a control switch 42, the circuit board 41 is limitingly installed between the base 18 and the second support 15. Wherein, the control switch 42 is arranged on the side of the circuit board 41 facing the adjusting piece 32, and the control switch 42 is used for controlling the atomization device 100 to start or shut down.

[0111] Further, referring to Figures 5-6 As shown, the adjusting piece 32 further comprises a trigger part 324, which is connected to the connecting plate part 323 and sleeved on the control switch 42, and the trigger part 324 is used for triggering the control switch 42 to start or shut down the atomization device 100.

[0112] Further, referring to Figure 3 As shown, when the adjusting piece 32 is located at the first position, the connecting plate part 323 blocks the air inlet end 171, the sealing piece blocks the liquid guide hole 131, and the trigger part 324 closes the control switch 42. Therefore, only under the action of controlling the adjusting piece 32, the atomization device 100 is simultaneously disconnected from the circuit (i.e. shut down), the air path and the liquid path. Therefore, the atomization device 100 can be effectively prevented from being triggered by mistake.

[0113] Referring to Figure 11 As shown, when the adjusting piece 32 is located at the first sub-position, the first sub-air inlet hole 3231 communicates the airflow channel with the adjusting hole 1121, the blocking piece 31 moves a first distance along the central axis 331 relative to the connecting piece 33, and extends into the liquid storage cavity 14 at the first sub-conductive position, and the trigger part 324 opens the control switch 42. Therefore, only under the action of controlling the adjusting piece 32, the circuit of the atomization device 100 is connected (i.e. turned on), the air path is connected, and the liquid path is connected.

[0114] Referring to Figure 12 As shown, when the adjusting piece 32 is located at the second sub-position, the second sub-air inlet hole 3232 communicates the airflow channel with the adjusting hole 1121, the blocking piece 31 moves a second distance along the central axis 331 relative to the connecting piece 33, and extends into the liquid storage cavity 14 at the second sub-conductive position, and the trigger part 324 opens the control switch 42. Therefore, only under the action of controlling the adjusting piece 32, the circuit of the atomization device 100 is connected (i.e. turned on), the air path is connected, and the liquid path is connected.

[0115] Preferably, the control switch 42 can also have a switch with two gears, a low gear and a high gear. When the control switch 42 is in the low gear state, the heating element 25 generates heat at a first power, and when the control switch 42 is in the high gear state, the heating element 25 generates heat at a second power. The second power is greater than the first power.

[0116] Further, referring to Figure 11 , when the adjusting member 32 is in the first sub-position, the trigger portion 324 turns on the control switch 42 and makes the control switch 42 in the low gear state. At this time, the heating element 25 generates heat at the first power to atomize the aerosol substrate.

[0117] Referring to Figure 12 , when the adjusting member 32 is in the second sub-position, the trigger portion 324 turns on the control switch 42 and makes the control switch 42 in the high gear state. At this time, the heating element 25 generates heat at the first power to atomize the aerosol substrate.

[0118] Further, referring to Figure 3 , the electric control assembly further includes a battery 43 and a charging interface 44. The battery 43 is accommodated in the housing 11 and is electrically connected with the circuit board 41, for supplying power to the circuit board 41, the control switch 42, the heating element 25 and other electric components. The charging interface 44 is electrically connected with the circuit board 41 and is provided on the housing 11, for being electrically connected with a power supply to charge the battery 43.

[0119] Further, referring to Figure 4 , Figure 6 , Figure 12 and Figure 14 , the adjusting member 32 and the base 18 are provided with a matched elastic clamping structure. The elastic clamping structure is used to limit the adjusting member 32 in one of the first position, the first sub-position and the second sub-position. By providing the elastic clamping structure, the risk of the adjusting member 32 being mistakenly touched between the first position, the first sub-position and the second sub-position can be further reduced.

[0120] Further, in an embodiment, referring to Figure 6As shown, the adjusting member 32 comprises a first elastic clamping arm 325 and a second elastic clamping arm 326. The first elastic clamping arm 325 and the second elastic clamping arm 326 are arranged on opposite sides of the connecting plate portion 323 along the direction of movement of the adjusting member 32, and the first elastic clamping arm 325 has a first clamping portion 3251, and the second elastic clamping arm 326 has a second clamping portion 3261.

[0121] As shown in Figure 4 , Figure 12 and Figure 14 As shown, the base 18 comprises a first clamping groove 181, a second clamping groove 182 and a third clamping groove 183 corresponding to the first clamping portion 3251 respectively, and a fourth clamping groove 184, a fifth clamping groove 185 and a sixth clamping groove 186 corresponding to the second clamping portion 3261 respectively.

[0122] As shown in Figure 4 , the first clamping portion 3251 and the first clamping groove 181 limit each other, and the second clamping portion 3261 and the fourth clamping groove 184 limit each other, and in this case, the adjusting member 32 is located at the first position.

[0123] As shown in Figure 12 , the first clamping portion 3251 and the second clamping groove 182 limit each other, and the second clamping portion 3261 and the fifth clamping groove 185 limit each other, and in this case, the adjusting member 32 is located at the first sub-position.

[0124] As shown in Figure 14 , the first clamping portion 3251 and the third clamping groove 183 limit each other, and the second clamping portion 3261 and the sixth clamping groove 186 limit each other, and in this case, the adjusting member 32 is located at the second sub-position.

[0125] Preferably, the first clamping portion 3251 and the second clamping portion 3261 are arranged opposite to each other in the horizontal plane, and the connecting line between the first clamping portion 3251 and the second clamping portion 3261 is perpendicular to the direction of movement of the adjusting member 32 in the horizontal plane.

[0126] Further, as shown in Figure 2 , in an embodiment, the adjusting hole 1121 and the suction nozzle 1111 are located on opposite sides of the shell 11 respectively. That is to say, the adjusting hole 1121 is formed on the second shell 112 and located on the side of the second shell 112 away from the first shell 111. Therefore, in the state of holding the atomization device 100 and the suction nozzle 1111 upward, the adjusting hole 1121 is located at the bottom of the atomization device 100, so as to further reduce the risk of the adjusting portion 321 being touched by mistake.

[0127] Preferably, the adjusting part 321 does not protrude from the adjusting hole 1121, so that the risk of the adjusting part 321 being mistakenly touched can be further reduced.
