Description

Technical Field

[0001] The present application relates to the technical field of aerosol generating devices, and in particular, to an atomizing device. Background Art

[0002] Atomizer is a device that can heat liquid aerosol matrix to generate aerosol. Affected by changes in the environment in which the atomizer is located, the liquid aerosol matrix contained in the liquid storage chamber of the atomizer is at risk of leaking from the liquid storage chamber. For example, when the temperature of the environment in which the aerosol matrix is ​​located increases, the liquid aerosol matrix will expand, resulting in an increase in the pressure in the liquid storage chamber, thereby causing the aerosol matrix to leak. For example, when the atomizer is left stationary for a long time with the liquid guide hole facing downward, the aerosol matrix is ​​also at risk of leakage due to the influence of gravity. For example, during long-distance transportation, the aerosol matrix shakes in the atomizer, the temperature of the aerosol matrix increases and expands, resulting in an increase in the pressure in the liquid storage chamber, thereby causing the aerosol matrix to leak. Therefore, an atomizer that can block the liquid guide hole came into being.

[0068] See also Figure 1-5 As shown, the present application provides an atomization device 100, which includes a housing assembly, an atomization assembly and an adjustment assembly 30. The atomization assembly is arranged in the housing assembly, and the adjustment assembly 30 is arranged on the housing assembly, and the adjustment assembly 30 is used to adjust the aerosol matrix contained in the housing assembly to flow to the atomization assembly.

[0069] Furthermore, the shell assembly is structured to form a liquid storage chamber 14, a liquid guide hole 131, a buffer chamber 132 and an adjustment hole 1121. The liquid storage chamber 14, the liquid guide hole 131 and the buffer chamber 132 are respectively located in the shell assembly, and the liquid guide hole 131 connects the liquid storage chamber 14 and the buffer chamber 132 to form a liquid path for supplying aerosol matrix to the atomization assembly.

[0070] The atomization assembly is disposed in the housing assembly and is at least partially located in the buffer chamber 132. The atomization assembly is used to heat the aerosol matrix when powered on, so that the heated aerosol matrix is ​​atomized to generate an aerosol.

[0071] By providing the buffer chamber 132, a small amount of aerosol matrix can be buffered to keep the liquid-conducting cotton 24 in the atomizing assembly in a wet state, thereby ensuring that the aerosol matrix on the liquid-conducting cotton 24 can be atomized to generate aerosol during the first inhalation after startup, thereby avoiding dry burning of the liquid-conducting cotton 24 to produce a burnt smell that affects the user experience.

[0072] Furthermore, the adjustment component 30 includes a blocking member 31 and an adjustment member 32. The adjustment member 32 is used to adjust the blocking member 31 to block the liquid guide hole 131 or to open the liquid guide hole 131.

The guide portion 3123 is limited in the guide groove 122, and when the blocking member 31 moves along the direction of the central axis 331, at least one guide portion 3123 slides in the corresponding guide groove 122.

[0093] By arranging the guide groove 122 and the guide portion 3123 to limit each other, the blocking member 31 can be prevented from circumferentially rotating during the movement along the length direction of the central axis 331 .

[0094] For further information, see Figure 2 as well as Fig.10 As shown, the housing assembly further includes a second bracket 15. The second bracket 15 is disposed in the housing 11, and is located on a side of the first bracket 12 away from the first sealing member 13, and a limiting hole 151 is formed on a side of the second bracket 15 close to the connecting member 33.

[0095] See also Figure 2 , Figure 5 as well as Figure 8 As shown, the connecting member 33 also includes 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 direction of the central axis 331, and is passed through 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 is abutted against the side of the limiting hole 151 close to the liquid guide hole 131.

[0096] The connecting member 33 is limited by setting the limiting hole 151 so that the connecting member 33 can rotate more stably along the central axis 331. In the spiral connection state between the first connecting part 312 and the second connecting part 332, the limiting hole 151 and the limiting stop part 335 can effectively limit the reaction force of the blocking member 31 on the connecting member 33 to affect the connection between the third connecting part 333 and the driving part 322, so that the connecting member 33 can stably drive the blocking member 31 to move along the direction of the central axis 331 under the drive of the adjusting member 32.

[0097] Further, the third connection part 333 is meshedly connected with the driving part 322. In one embodiment, the third connection part 333 is gear-shaped, and the driving part 322 is rack-shaped.

[0098] Furthermore, the atomizer assembly and the housing assembly are jointly constructed to form an airflow channel. Specifically, the inner tube 22, the suction nozzle 1111, the first bracket 12 and the second bracket 15 are jointly constructed to form the airflow channel.

[0099] For further information, see Figure 5-6 As shown, the adjusting member 32 further includes a connecting plate portion 323. The driving portion 322 and the adjusting portion 321 are respectively connected to the connecting plate portion 323, and the connecting plate portion 323 has an air inlet hole, and the air inlet hole is used to connect the air flow channel.

[0100] For further information, see Figure 2 As shown, when the adjusting member 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 be circulated, and at the same time, the blocking member 31 is located at the blocking position and blocks the liquid guide hole 131 so that the aerosol matrix in the liquid storage chamber 14 cannot move toward the atomizing assembly. Thus, the blocking of the liquid guide hole 131 and the blocking of the airflow channel are controlled simultaneously by the adjusting member 32.

[0101] See also Figure 3 As shown, when the adjusting member 32 is in the second position, the air inlet hole connects the adjusting hole 1121 and the air inlet end 171 of the air flow channel so that the air flow channel can be circulated with air, and at the same time, the blocking member 31 is in the conducting position and opens the liquid conducting hole 131. Thus, the conducting of the liquid conducting hole 131 and the conducting of the air flow channel are controlled simultaneously by the adjusting member 32.

[0102] Furthermore, in one embodiment, when the blocking member 31 is in the blocking position, the blocking portion 311 is located in the liquid conducting hole 131 , and when the blocking member 31 is in the conducting position, the blocking portion 311 extends out of the liquid conducting hole 131 in a direction away from the liquid storage chamber 14 .

[0103] Preferably, see Figure 3 As shown, in another embodiment, the liquid storage cavity 14 contains liquid storage cotton 141. When the blocking member 31 is located at the conducting position, the blocking portion 311 passes through the liquid conducting hole 131 and extends into the liquid storage cavity 14 to press the liquid storage cotton 141, so that the liquid conducting cotton 24 releases the locked aerosol matrix more quickly under the squeezing action of the blocking portion 311, so that the released aerosol matrix quickly enters the cache cavity 132 through the liquid conducting hole 131, thereby improving the supply speed of the aerosol.

[0104] For further information, see Figure 11-14 As shown, the conduction position includes a first sub-conduction position and a second sub-conduction 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.

[0105] When the adjusting member 32 is located at the first sub-position, the first sub-air inlet hole 3231 connects the air flow channel with the adjusting hole 1121, and the blocking member 31 moves a first distance relative to the connecting member 33 along the direction of the central axis 331, and extends into the liquid storage chamber 14 to be located at the first sub-conduction position.

[0106] When the adjusting member 32 is located at the second sub-position, the second sub-air inlet hole 3232 connects the air flow channel with the adjusting hole 1121, and the blocking member 31 moves a second distance relative to the connecting member 33 along the direction of the central axis 331, and extends into the liquid storage chamber 14 to be located at the second sub-conduction position.

[0107] Furthermore, the second distance is greater than the first distance, so that when the blocking member 31 is located at the second sub-conduction position, the degree of squeezing the liquid storage cotton 141 is greater than when the blocking member 31 is located at the first sub-conduction position. Therefore, when the blocking member 31 is located at the second sub-conduction position, the liquid storage cotton 141 can be further squeezed to release the locked aerosol matrix, so that the supply amount of the aerosol matrix is ​​larger.

[0108] Furthermore, because the aperture of the second sub-air inlet hole 3232 is larger than the aperture of the first sub-air inlet hole 3231, when the adjusting member 32 is in the second sub-position, the amount of air entering the air flow channel through the second sub-air inlet hole 3232 is greater than the amount of air entering the air flow channel through the first sub-air inlet hole 3231 when the adjusting member 32 is in the first sub-position, thereby making the supply amount of the aerosol matrix and the amount of air flow directly proportional to each other when the adjusting member 32 is in different position states.

[0109] For further information, see Figure 3-4 as well as Figure 11-14 As shown, the housing assembly further includes a second seal 16 and a third seal 17. The second seal 16 is sealed and connected between the first bracket 12 and the second bracket 15, and the third seal 17 is provided between the second bracket 15 and the connecting plate portion 323. The suction nozzle 1111, the inner tube 22, the first bracket 12, the second seal 16, the second bracket 15 and the third seal 17 are jointly constructed to form the air flow channel, and the third seal 17 is constructed to form an air inlet end 171 of the air flow channel.

[0110] See also Figure 3-4 As shown, when the adjusting member 32 is located at the first position, the connecting plate portion 323 blocks the air inlet end 171 , thereby blocking the air flow channel.

[0111] Furthermore, the housing assembly further includes a base 18. The base 18 is disposed in the housing 11, and together with the housing 11, forms a mounting cavity 19. The adjusting member 32 is disposed in the mounting cavity 19, and the base 18 and the first bracket 12 are connected by a mutual snap connection to limit the second sealing member 16, the second bracket 15 and the third sealing member 17 between the first bracket 12 and the adjusting member 32.

[0112] Please continue reading Figure 3-4As shown, the atomizing device 100 further includes an electric control component, which includes a circuit board 41 and a control switch 42, and the circuit board 41 is limitedly installed between the base 18 and the second bracket 15. The control switch 42 is arranged on a side of the circuit board 41 facing the adjusting member 32, and the control switch 42 is used to control the atomizing device 100 to turn on or off.

[0113] For further information, see Figure 5-6 As shown, the adjusting member 32 further includes a trigger portion 324, which is disposed on the connecting plate portion 323 and sleeved on the control switch 42, and is used to trigger the control switch 42 to turn on or off the atomizing device 100.

[0114] For further information, see Figure 3 As shown, when the adjusting member 32 is located at the first position, the connecting plate portion 323 blocks the air inlet end 171, the sealing member blocks the liquid guide hole 131, and the trigger portion 324 turns off the control switch 42. Thus, only under the control of the adjusting member 32, the atomizing device 100 is disconnected from the circuit (i.e., shut down), the air circuit, and the liquid circuit. Therefore, the atomizing device 100 can be effectively prevented from being triggered by mistake.

[0115] See also Fig.11 As shown, when the adjusting member 32 is located at the first sub-position, the first sub-air inlet hole 3231 connects the airflow channel with the adjusting hole 1121, the blocking member 31 moves a first distance relative to the connecting member 33 along the direction of the central axis 331, and extends into the liquid storage chamber 14 to be located at the first sub-conduction position, and the triggering part 324 turns on the control switch 42. Thus, only under the control of the adjusting member 32, the circuit conduction (i.e., power-on), gas path conduction, and liquid path conduction of the atomizing device 100 are achieved.

[0116] See also Fig.12 As shown, when the adjusting member 32 is located at the second sub-position, the second sub-air inlet hole 3232 connects the airflow channel with the adjusting hole 1121, the blocking member 31 moves a second distance relative to the connecting member 33 along the direction of the central axis 331, and extends into the liquid storage chamber 14 to be located at the second sub-conduction position, and the triggering part 324 turns on the control switch 42. Thus, only under the control of the adjusting member 32, the circuit conduction (i.e., power-on), gas path conduction, and liquid path conduction of the atomizing device 100 are achieved.

[0117] Preferably, the control switch 42 may also have 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.

[0118] For further information, see Fig.11 As shown, when the adjusting member 32 is in the first sub-position, the triggering unit 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 matrix.

[0119] See also Fig.12 As shown, when the adjusting member 32 is in the second sub-position, the triggering unit 324 turns on the control switch 42 and makes the control switch 42 in the high position. At this time, the heating element 25 generates heat at the first power to atomize the aerosol matrix.

[0120] For further information, see Figure 3 As shown, 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 to the circuit board 41, and is used to supply power to the circuit board 41, the control switch 42, the heating element 25 and other electrical components. The charging interface 44 is electrically connected to the circuit board 41, and is provided on the housing 11, and is used to be electrically connected to the power supply to charge the battery 43.

[0121] For further information, see Figure 4 , Figure 6 , Fig.12 and Fig.14 As shown, a mutually cooperating elastic clamping structure is provided between the adjusting member 32 and the base 18. The elastic clamping structure is used to limit the adjusting member 32 to 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 accidentally touched between the first position, the first sub-position and the second sub-position can be further reduced.

[0122] Further, in one embodiment, see Figure 6As shown, the adjusting member 32 includes 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.

[0123] See also Figure 4 , Fig.12 and Fig.14 As shown, the base 18 includes a first card slot 181, a second card slot 182 and a third card slot 183 corresponding to the first card holding portion 3251 respectively, and a fourth card slot 184, a fifth card slot 185 and a sixth card slot 186 corresponding to the second card holding portion 3261 respectively.

[0124] Among them, see Figure 4 As shown, when the first clamping portion 3251 and the first clamping slot 181 are mutually limited, and the second clamping portion 3261 and the fourth clamping slot 184 are mutually limited, the adjusting member 32 is located at the first position.

[0125] See also Fig.12 As shown, when the first clamping portion 3251 and the second clamping slot 182 are mutually limited, and the second clamping portion 3261 and the fifth clamping slot 185 are mutually limited, the adjusting member 32 is located at the first sub-position.

[0126] See also Fig.14 As shown, when the first clamping portion 3251 and the third clamping slot 183 are mutually limited, and the second clamping portion 3261 and the sixth clamping slot 186 are mutually limited, the adjusting member 32 is located at the second sub-position.

[0127] Preferably, the first clamping portion 3251 and the second clamping portion 3261 are disposed opposite to each other in a horizontal plane, and a connecting line between the first clamping portion 3251 and the second clamping portion 3261 and a moving direction of the adjusting member 32 are perpendicular to each other in the horizontal plane.

[0128] For further information, see Figure 2 As shown, in one embodiment, the adjustment hole 1121 and the suction nozzle 1111 are respectively located on opposite sides of the housing 11. That is, the adjustment hole 1121 is opened on the second housing 112 and is located on the side of the second housing 112 away from the first housing 111. Therefore, when the atomizing device 100 is held with the suction nozzle 1111 facing upward, the adjustment hole 1121 is located at the bottom of the atomizing device 100, thereby further reducing the risk of the adjustment portion 321 being accidentally touched.

[0129] Preferably, the adjusting portion 321 does not extend out of the adjusting hole 1121 , thereby further reducing the risk of the adjusting portion 321 being accidentally touched.

[0130] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0131] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0132] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
