Technical Field

[0001] The utility model relates to the technical field of aerosol atomization, and particularly relates to an aerosol generating device. Background Art

[0002] In the electronic atomization industry, users have different requirements for the size of aerosol. Currently, the common and widely used one is single-region atomization (i.e., single-shot atomization core), and there are the most market products. The industry has made differential innovations for user experience. For users' requirements for the amount of aerosol, dual-region or single-region atomization aerosol products have been gradually developed, and it has become a new development trend in the industry.

Components such as the control board 3, the induction component 4, and the battery 5 are installed in the second installation cavity 12.

[0051] Please refer to Figure 2 , in this embodiment, the atomization core 2 includes an atomization shell 21, an atomization cylinder 22, a liquid storage matrix 23, and a heating element 24. One end of the atomization shell 21 is plugged into the first installation cavity 11 of the housing 1, and a mouthpiece is provided at the other end of the atomization shell 21. The atomization cylinder 22 is installed inside the atomization shell 21.

The liquid storage matrix 23 is a cylindrical structure, and the heating element 24 can be installed on the inner side surface of the liquid storage matrix 23. The through hole of the liquid storage matrix 23 is for ventilation, and the heating element 24 is used for heating the atomization matrix attached to the liquid storage matrix 23 to form smoke.

[0052] Please refer to Figure 3, the atomization core 2 includes a plurality of heating elements 24, and the plurality of heating elements 24 are distributed in different regions on the inner side surface of the liquid storage matrix 23. The plurality of heating elements 24 can be distributed along the axial or radial direction of the inner side surface of the liquid storage matrix 23. In this embodiment, the atomization core 2 having two heating elements 24 is described. The atomization core 2 includes a first heating element 241 and a second heating element 242. The first heating element 241 and the second heating element 242 are distributed along the radial direction of the inner side surface of the liquid storage matrix 23. The first heating element 241 and the second heating element 242 are respectively arc-shaped structures, and the two arc-shaped structures can form a complete cylindrical structure or a cylindrical structure with a radial opening.

[0053] One end of the atomization core 2 inserted into the first installation cavity 11 is provided with a second conductive terminal 26. The second conductive terminal 26 can be set according to the number of heating elements 24, so that the plurality of heating elements 24 are arranged on a parallel circuit, and separate heating and combined heating can be realized.

[0054] In other embodiments, the atomization core 2 does not have a mouthpiece, and the housing 1 can further include a mouthpiece. The mouthpiece is detachably installed at one end of the housing 1, and the mouthpiece can cover the first installation cavity 11 to fix the atomization core 2 in the housing 1.

[0055] In other embodiments, the atomization core 2 can also be other atomization heating structures. For example, the atomization core 2 includes a plug-in cylinder and a heating element. The plug-in cylinder is used to plug in the atomization matrix of the cigarette stick, and the heating element is located on the circumferential outer side or inner side of the plug-in cylinder. The heating element is used to heat the atomization matrix in the plug-in cylinder.

[0056] In this embodiment, the atomization core 2 includes three second conductive terminals 26. One of the second conductive terminals 26 is a positive terminal, and the second conductive terminal 26 of the positive terminal is connected to both the first heating element 241 and the second heating element 242. The other two second conductive terminals 26 are negative terminals, and the second conductive terminals 26 of the two negative terminals are connected to the first heating element 241 and the second heating element 242 in a one-to-one correspondence.

[0057] In this embodiment, the bottom of the first installation cavity 11 can be provided with a first conductive terminal 14. The number and position of the first conductive terminal 14 correspond to those of the second conductive terminal 26. The bottom of the first installation cavity 11 is provided with three first conductive terminals 14. The first conductive terminal 14 protrudes from the bottom of the first installation cavity 11, and the other end of the first conductive terminal 14 passes through the sealing silica gel 13 and is electrically connected to the control board 3. The first conductive terminal 14 is used to be electrically connected to the second conductive terminal 26 of the atomization core 2.

[0058] The control board 3 is also electrically connected to the battery 5. The control board 3 is electrically connected to the first heating element 241 and the second heating element 242 through the first conductive terminal 14 and the second conductive terminal 26, and the control board 3 is used to control the separate heating or combined heating of the first heating element 241 and the second heating element 242.

[0059] An installation rack 15 is provided in the second installation cavity 12. The battery 5 can be installed on the installation rack 15, and the installation rack 15 can be fixedly connected to the housing 1 by means of snap connection, screw connection, etc. The installation rack 15 can also be an integral structure with the housing 1.

[0060] Please refer to Figure 6 and Figure 7 , in this embodiment, the induction assembly 4 includes an induction housing 41, a moving member 42 and an induction member 43. The induction housing 41 can be fixedly installed on the control board 3, and the induction housing 41 can also be directly installed on the inner side wall of the housing 1. An induction cavity 411 is provided in the induction housing 41, and the moving member 42 is movably installed in the induction cavity 411, and the moving member 42 can roll in the induction cavity 411.

[0061] Wherein, the height of the induction cavity 411 is slightly greater than the height of the moving member 42, which can prevent the moving member 42 from running around in the induction cavity 411 and play a role in limiting.

[0062] The induction cavity 411 has a first gear position 4111 and a second gear position 4112, and the moving member 42 can move back and forth between the first gear position 4111 and the second gear position 4112.

[0063] Part of the induction member 43 is arranged in the induction cavity 411 and is located at the first gear position 4111. Part of the induction member 43 can be exposed outside the induction cavity 411 and electrically connected to the control board 3. The exposed part of the induction member 43 can be directly electrically connected to the control board 3 by means of welding, etc., and the exposed part of the induction member 43 can also be electrically connected to the control board 3 through a cable. The induction member 43 can also be entirely located in the induction cavity 411, and the induction member 43 is electrically connected to the control board 3 through conductive connectors such as circuits.

[0064] The induction member 43 can include two electrical contacts in the form of gold fingers, and the moving member 42 is a conductive structure such as a conductive metal roller. When the moving member 42 rolls to the first gear position 4111, the moving member 42 contacts the induction member 43, and the moving member 42 contacts the two electrical contacts at the same time, so that the two electrical contacts are conducted and a trigger signal can be generated. After the control board 3 receives the trigger signal, the atomization core 2 is controlled to switch to the heating area of the first gear.

[0065] In other embodiments, the moving member 42 can also be a metal ball with a larger diameter, and the distance between the two electrical contacts is less than the diameter of the metal ball. The metal ball can also realize electrical connection with the two electrical contacts at the same time to trigger the induction member 43 to generate a trigger signal.

[0066] In this embodiment, the housing 1 is a long strip structure. The housing 1 has a central axis along the length direction. The induction cavity 411 has a radial plane perpendicular to the central axis. The first gear position 4111 and the second gear position 4112 are located on this radial plane. It should be noted that the first gear position 4111 and the second gear position 4112 being located on the radial plane means that the first gear position 4111 and the second gear position 4112 are distributed along the radial plane, that is, the first gear position 4111 and the second gear position 4112 are distributed along the radius of the housing 1. With such a setting, tilting the housing 1 in different directions can cause the moving part 42 to roll to different target positions.

[0067] In this embodiment, the housing 1 is a long and flat structure. The circumferential side surface of the housing 1 includes a wide surface and a narrow surface. The housing 1 has a middle dividing plane parallel to the wide surface, where the wide surface includes a first wide surface 17 and a second wide surface 18 that are parallel to each other. The induction cavity 411 is a cavity extending in a straight line. The middle dividing plane is located at both ends of the induction cavity 411, and the first gear position 4111 and the second gear position 4112 are located on both sides of the middle dividing plane of the housing 1. With such a setting, flipping and tilting the housing 1 can achieve controlling the moving part 42 to move back and forth between the first gear position 4111 and the second gear position 4112, and the operation is simple.

[0068] In this embodiment, the two gears for the induction component 4 to switch are two gears with different heating areas. When the moving part 42 rolls to the first gear position 4111, the first heating mode is triggered. When the moving part 42 rolls to the second gear position 4112, the second heating mode is triggered. The first heating mode and the second heating mode have different heating areas, and users can switch and use the corresponding heating areas according to their needs.

[0069] In this embodiment, the aerosol generating device can switch between the first gear and the second gear by tilting forward and backward:

[0070] Please refer to Figure 8 , when the user tilts the housing 1 with the first wide surface 17 facing upward, it is in the first gear state. The induction cavity 411 is tilted, the first gear position 4111 is lower than the second gear position 4112, and the moving part 42 rolls under the action of gravity and rolls to the first gear position 4111. At this time, the moving part 42 contacts the induction part 43, and the induction part 43 generates a trigger signal. When the control board 3 receives this trigger signal, it controls the atomization core 2 to switch to the first heating mode, that is, controls the first heating element 241 to heat alone, or can also control the second heating element 242 to heat alone, and heats a relatively small area to achieve preheating;

[0071] Please refer to Figure 9, when the user flips the housing 1 by 180° so that it is inclined on the second wide surface 18 (the wide surface parallel to the first wide surface 17) and is in the second gear state, the induction cavity 411 is inclined in the opposite direction, the second gear position 4112 is lower than the first gear position 4111, and the moving part 42 rolls to the other end under the action of gravity and rolls to the second gear position 4112. At this time, the moving part 42 is separated from the induction part 43, and the induction part 43 does not generate a trigger signal. The control board 3 does not receive this trigger signal, so it controls the atomization core 2 to switch to the second heating mode, that is, it controls the first heating element 241 and the second heating element 242 to heat simultaneously to heat a relatively large area to achieve rapid heating. The heating area in the second gear is larger than that in the first gear.

[0072] In this embodiment, an air intake channel is further provided in the housing 1. The air intake channel is communicated with the air guiding channel in the atomization core 2. The aerosol generating device further includes a start sensor 6 (also called a microphone head). The start sensor 6 is communicated with the air intake channel, and the start sensor 6 is also electrically connected to the control board 3. The start sensor 6 is used to detect the air pressure in the air intake channel. When the user sucks, an air flow will be generated in the air intake channel, and the air pressure will drop. When the start sensor 6 detects the drop in air pressure, it triggers the control board 3 to control the atomization core 2 to start heating; when the user stops sucking, no air flow is generated in the air intake channel, the air pressure rises, and when the start sensor 6 detects the rise in air pressure, it triggers the control board 3 to control the atomization core 2 to stop heating.

[0073] A microphone head silica gel 16 is further provided in the second installation cavity 12. The microphone head silica gel 16 serves as a sealing structure for the start sensor 6. The microphone head silica gel 16 wraps the start sensor 6 to improve the airtightness of the connection between the start sensor 6 and the air intake channel.

[0074] In other embodiments, the aerosol generating device may also be provided with a key switch. The key switch is electrically connected to the control board 3, and the start heating and stop heating of the atomization core 2 can also be realized through the key switch.

[0075] In the aerosol generating device of this embodiment, since the moving part 42 in the induction assembly 4 can be tilted and moved to the first gear position 4111 and the second gear position 4112 to switch between the first gear and the second gear, and the first gear and the second gear have different heating areas, the user only needs to control different tilting states of the housing 1 to achieve the switching of different heating modes. The user does not need to adjust the heating area with fingers, which can improve the convenience and accuracy of heating area adjustment, and can also reduce the user's operation fatigue, having a better use experience effect.

[0076] The sensing component 4 in this embodiment is also combined with the user's suction use state, enabling gear combination in the normal suction state of the user without affecting the user's suction posture. Specifically, when the user is sucking normally, the aerosol generating device is generally in an inclined state. This sensing component 4 utilizes the characteristic of the inclined smoking device during sucking. When the aerosol generating device is tilted with different wide faces facing up, the aerosol generating device is still in a normal inclined state for the user to suck, without the need to adjust the aerosol generating device to other inclined states different from the normal inclined state, which can improve the user experience.

[0077] In one embodiment, the atomization core 2 may include other numbers of heating elements 24. For example, it includes four heating elements 24. The number of heating elements 24 controlled in the first gear and the second gear can be different. For example, in the first gear state, one or two of the four heating elements 24 are controlled to heat, and in the second gear state, three or four of the four heating elements are controlled to heat. It can also achieve heating in different regions to meet different usage requirements.

[0078] Please refer to Figure 7 , in one embodiment, the sensing cavity 411 has a bottom surface, which is the surface in the sensing cavity 411 away from the first installation cavity 11. The bottom surface of the sensing cavity 411 is the moving surface of the moving member 42, and a groove is provided on the bottom surface, and this groove forms a target position. For example, grooves are provided at both ends of the bottom surface, and the groove at one end forms the first gear position 4111, and the groove at the other end forms the second gear position 4112. The setting of the groove enables the moving member 42 to stop stably at the corresponding target position, ensuring the accuracy and stability of switching between different gears.

[0079] At the opening of the groove, there is a transition arc surface connected to the bottom surface of the sensing cavity 411, enabling the moving member 42 to more easily roll into and out of the groove (target position) when the user switches the housing 1 to different inclined states, which can improve the smoothness of the movement of the moving member 42.

[0080] The bottom surface of the sensing cavity 411 can be set as an arc surface, with the middle part of the bottom surface protruding. When the moving member 42 crosses the middle part of the bottom surface, it will roll faster to the corresponding target position, which can prevent the moving member 42 from accidentally rolling to other target positions and also prevent the moving member 42 from stopping at the middle position of the bottom surface.

[0081] In one embodiment, the sensing element 43 can also be other sensing components. For example, the sensing element 43 is also a pressure sensor or a gravity sensor. When the moving member 42 rolls into contact with the sensing element 43, the pressure sensor or the gravity sensor will detect a change in pressure or gravity and can also generate a corresponding trigger signal to control the atomization core 2 to switch the heating mode.

[0082] In one embodiment, a gear position identifier may be provided on the circumferential outer surface of the housing. For example, a first identifier is provided on the first wide surface 17 of the housing 1, and the first identifier corresponds to the first gear position. A second identifier is provided on the second wide surface 18, and the second identifier corresponds to the second gear position. When the first identifier is tilted upward, it means that the first wide surface 17 is upward, and the first heating mode corresponding to the first gear position is switched to; when the second identifier is tilted upward, it means that the second wide surface 18 is upward, and the second heating mode corresponding to the second gear position is switched to. The setting of the gear position identifier allows the user to clearly know the switched gear position and avoid the user switching to the wrong heating mode for inhalation.

[0083] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art of the present invention, based on the idea of the present invention, several simple deductions, deformations or substitutions can also be made.
