[0008] The liquid guiding component is arranged at the liquid guiding channel and has a plurality of liquid guiding holes connecting the atomizing channel and the liquid storage chamber. The cross-sectional dimensions of the liquid guiding holes can allow the aerosol matrix to be retained in the liquid guiding holes in a state without a pressure difference.

[0014] In some embodiments of the first aspect, the liquid storage tank housing is detachably connected to the atomization tank housing.

[0015] In some embodiments of the first aspect, the liquid storage cotton ring is disposed on the atomization core and at least partially blocks the channel opening of the liquid guide channel at the cavity wall of the installation cavity.

The liquid guide hole is limited by its own cross-sectional size, so that the aerosol matrix cannot flow in the liquid guide hole due to the combined effect of surface tension and its own viscosity, that is, the aerosol matrix can be retained in the liquid guide hole without a pressure difference, thereby avoiding leakage of the liquid storage component. When it is necessary to fill the aerosol matrix into the atomization channel, the compression cover can be switched from the release state to the compression state. At this time, the volume of the space above the aerosol matrix decreases, the pressure increases, and a pressure difference is generated.

The aerosol matrix in the liquid guide hole flows toward the liquid storage cavity under the action of the pressure difference.

In this way, a liquid filling process is completed. In this liquid filling process, the volume of the liquid storage space can be compressed to what extent according to the needs.

The flow rate of the aerosol matrix in the liquid guide hole can be adjusted according to the pressure size and change rate in the liquid storage space. In this way, the nebulizer can be filled with liquid according to the required amount of aerosol matrix, flexibly providing aerosol matrix replenishment and avoiding the situation where the aerosol matrix is ​​filled with liquid too quickly or too slowly.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] An embodiment of the present invention provides an aerosol generating device and an atomizer. The aerosol generating device includes the atomizer and a host. The host is detachably connected to the atomizer. A battery and a circuit board are arranged in the host. The battery is electrically connected to the circuit board, and the circuit board is electrically connected to the atomizer. The battery is used to power the atomizer, and the circuit board is used to control the atomizer to work.

[0032] See also Figure 1 and Figure 2 The atomizer includes an atomizing component 10, a liquid storage component 20 and a liquid guiding component 30.

[0033] The atomizing assembly 10 is formed with an atomizing channel 101 and a liquid guiding channel 102 connected to the atomizing channel 101. The atomizing assembly 10 is used to atomize an aerosol matrix.

[0034] The liquid storage assembly 20 includes a liquid storage tank shell 21 and a compression cap 22. The liquid storage tank shell 21 has a liquid storage cavity 201, an opening 202 and a connecting channel 203 connected to the liquid storage cavity 201. The opening 202 is located at the upper end of the liquid storage cavity 201, and the connecting channel 203 is located at the lower end of the liquid storage cavity 201. The liquid storage cavity 201 is used to store aerosol matrix. The aerosol matrix needs to cover the channel opening of the connecting channel 203 on the side of the liquid storage cavity 201. The opening 202 is located above the aerosol matrix. The liquid storage tank shell 21 is connected to the atomization channel 101 of the atomization assembly 10 through the connecting channel 203. The connecting channel 203 is connected to the liquid guide channel 102. The compression cap 22 covers the opening 202 and is enclosed together with the liquid storage tank shell 21 to form a liquid storage space. The liquid storage space is a sealed space. The compression cover 22 has a telescopic structure 2221, and can switch between a compressed state and a released state through the deformation of the telescopic structure 2221. When the compression cover 22 is in the compressed state, the volume of the liquid storage space is smaller than the volume of the liquid storage space when the compression cover 22 is in the released state. It should be noted that the compression cover 22 can maintain a relatively large volume when it is in the released state, and is in a compressed state when the volume is reduced. The compressed state can be when the liquid storage space is compressed to a certain specific volume, or when the volume of the liquid storage space is smaller than the volume in the released state, that is, the compressed state is a volume range, which is not limited here.

[0035] In the natural state, the compression cover 22 can maintain the released state, and when the compression cover 22 switches from the released state to the compressed state, the volume of the liquid storage space decreases. The compression cover 22 can switch between the compressed state and the released state by pressing or pulling with fingers, or by electric control, which is not limited here.

[0036] Please combine Figure 3 The liquid guiding component 30 is arranged at the liquid guiding channel 102, and is provided with a plurality of liquid guiding holes 301 connecting the atomizing channel 101 and the liquid storage chamber 201, wherein the liquid guiding component can be directly connected to the liquid guiding channel 102, or indirectly connected to the liquid guiding channel 102 by connecting to the connecting channel 203, as long as the liquid guiding holes 301 in the liquid guiding component can connect the atomizing channel 101 and the liquid storage chamber 201.

[0037] After the aerosol matrix is ​​added to the liquid storage chamber 201, the space above the aerosol matrix in the liquid storage chamber 201 is sealed due to the blocking of the aerosol matrix to the channel opening on the liquid storage chamber 201 side of the connecting channel 203. At this time, the air pressure in the space above the aerosol matrix is ​​equal to the atmospheric pressure. The liquid guide hole 301 can limit the cross-sectional size of itself, so that the aerosol matrix cannot flow in the liquid guide hole 301 due to the combined effect of surface tension and its own viscosity, that is, the aerosol matrix can be retained in the liquid guide hole 301 without a pressure difference, thereby preventing the liquid storage component 20 from leaking. When it is necessary to fill the aerosol matrix into the atomization channel 101, the compression cover 22 can be switched from the release state to the compression state. At this time, the volume of the space above the aerosol matrix decreases, the pressure increases, and a pressure difference is generated. The aerosol matrix in the liquid guide hole 301 flows toward the atomization channel 101 under the action of the pressure difference. In this way, the aerosol matrix in the liquid storage space can enter the atomization channel 101 through the liquid guide hole 301; when the compression cover 22 is switched from the compression state to the release state, the volume of the space above the aerosol matrix increases, the pressure decreases, and a pressure difference is generated. The aerosol matrix in the liquid guide hole 301 flows toward the liquid storage cavity 201 under the action of the pressure difference. In this way, the atmosphere can enter the liquid storage space through the liquid guide hole 301 until the air pressure in the liquid storage space is approximately equal to the atmospheric pressure. In this way, a filling process is completed. In this filling process, the volume of the liquid storage space can be compressed to what extent according to the needs. If the filling amount requirement is still not met when compressed to the minimum volume, the above filling process can be repeated until the filling amount meets the requirements. The flow rate of the aerosol matrix in the liquid guide hole 301 can be adjusted according to the pressure size and change rate in the liquid storage space. In this way, the atomizer can be filled according to the required amount of aerosol matrix, and the aerosol matrix can be flexibly supplied to avoid the situation where the aerosol matrix is ​​discharged too quickly or too slowly.

[0038] In other embodiments, the natural state of the compression cap 22 may also be maintained in a compressed state, as long as the compression cap 22 is in a released state when the aerosol matrix needs to be replenished into the atomization chamber, and there is no limitation here.

[0039] See also Figure 2In some embodiments, the liquid guiding member 30 includes a liquid guiding tube 31 disposed in the liquid guiding channel 102 and a liquid guiding plug 32 disposed in the liquid guiding tube 31. A liquid guiding groove 321 is provided on the peripheral side wall of the liquid guiding plug 32. The groove wall of the liquid guiding groove 321 and the inner tube wall of the liquid guiding tube 31 are jointly formed to form a liquid guiding hole 301. The liquid guiding groove 321 is convenient to process relative to the hole structure. At the same time, after long-term use, the liquid guiding plug 32 can be directly taken out of the liquid guiding tube 31 to clean the solidified liquid fat on the groove wall of the liquid guiding groove 321 and the tube wall of the liquid guiding tube 31. There is no need to make a cleaning tool separately to penetrate the hole structure for dredging, which is convenient for rapid cleaning of the liquid fat.

[0040] Optionally, the maximum width of the cross section of the liquid guide hole 301 is less than or equal to 0.5 mm. Under this cross-sectional size, it can be ensured that the aerosol matrix can be retained in the liquid guide hole 301 by the combined effect of its own surface tension and its own viscosity, and cannot flow in the liquid guide hole 301, thereby preventing the liquid storage component 20 from leaking. Among them, the cross section of the liquid guide hole 301 is perpendicular to the central axis of the liquid guide hole 301.

[0041] Optionally, a plurality of liquid guiding grooves 321 are provided, and the plurality of liquid guiding grooves 321 are arranged at equal intervals along the circumference of the liquid guiding plug 32. The provision of a plurality of liquid guiding grooves 321 can increase the flow rate of the aerosol matrix. Wherein, under different liquid filling requirements, the liquid guiding plug 32 with different numbers of liquid guiding grooves 321 can be replaced.

[0042] In other embodiments, the liquid guide plug 32 is also provided with a plurality of hole-shaped liquid guide holes 301, which is not limited here. When the liquid guide plug 32 is provided with the liquid guide holes 301, the liquid guide tube 31 may not be provided, but the liquid guide plug 32 is adapted and plugged with the liquid guide channel 102 or the connecting channel 203.

[0043] Optionally, a baffle 112 may be covered at the channel opening of one end of the liquid guiding channel 102 close to the atomization channel 101, and a guide groove 1121 and at least one guide hole 1122 provided at the bottom of the guide groove 1121 are provided on the baffle 112. The liquid guiding plug 32 abuts against the baffle 112, and the aerosol matrix flowing out of the liquid guiding hole 301 may enter the liquid guiding groove 321 and flow out through the guide hole 1122 guided by the liquid guiding groove 321, so as to avoid leakage of the aerosol matrix due to too wide a distribution area of ​​the aerosol matrix flowing out of the liquid guiding channel 102.

[0044] In some embodiments, the telescopic structure 2221 is elastic and can apply elastic force to the compression cover 22 to restore it to the released state when the compression cover 22 is in the compressed state. In this way, the telescopic structure 2221 can automatically restore the compression cover 22 to the released state through its own elastic force, so as to achieve rapid reset of the compression cover 22.

[0045] See also Figure 2 Optionally, the compression cap 22 includes a top cover portion 221 and a peripheral side portion 222, the peripheral side portion 222 is arranged around the top cover portion 221 and forms a tubular shape, and the peripheral side portion 222 and the top cover portion 221 are jointly arranged to form a cover inner space 220. It can be understood that the top cover portion 221 and the peripheral side portion 222 jointly form a cylindrical structure with one end sealed, and the space inside the cylindrical structure is the cover inner space 220, and the opening 202 of the cylindrical structure away from the end of the top cover portion 221 is connected to the liquid storage cavity 201. The liquid storage space includes the cover inner space 220 and the warehouse inner space, that is, the space below the bottom opening 202 of the compression cap 22 is the warehouse inner space, and the warehouse inner space is used to store the aerosol matrix. Among them, a threaded tubular telescopic structure 2221 is formed on the peripheral side portion 222, so that the peripheral side portion 222 can perform axial telescopic deformation. When liquid filling is required, the top cover portion 221 can be pressed, and the peripheral side portion 222 is compressed and deformed along the axial direction under the axial pressure of the top cover portion 221, and the compression cover 22 switches to a compressed state, and the space 220 inside the cover is reduced. Therefore, the volume of the liquid storage space is reduced. After the liquid filling process is completed, the top cover portion 221 is released by the finger, and the peripheral side portion 222 stretches under the elastic force of the threaded tubular telescopic structure 2221, and the compression cover 22 switches to a released state, and the space 220 inside the cover is increased. Therefore, the volume of the liquid storage space is increased. The threaded tubular telescopic structure 2221 can be telescopically deformed in any interval in the axial direction. That is to say, the top cover does not need to be pressed to the bottom when pressed, and the top cover does not need to be reset to the top when reset. The pressing displacement and release displacement of the top cover part 221 can be selected according to the specific situation during the filling process, thereby improving the flexibility of aerosol matrix replenishment.

[0046] Optionally, the compression cover 22 further includes a connecting portion 223, which is disposed around the bottom end of the peripheral side portion 222 and is sealed and connected to the opening 202 of the liquid storage cavity 201. When the compression cover 22 is in a released state, the top cover portion 221 may protrude from the liquid storage tank housing 21 for easy pressing.

[0047] In other embodiments, the peripheral side portion 222 may also be supported by a flexible material. In this case, the telescopic structure 2221 may be an elastic member such as a spring connected between the connecting portion 223 and the top cover portion 221 .

[0048] See also Figure 2In some embodiments, the atomizer assembly 10 includes an atomizer housing 11, an atomizer core 12, and a liquid storage cotton 123. The atomizer housing 11 is formed with a mounting cavity, and an air inhalation channel 103 and a liquid guide channel 102 connected to the mounting cavity. A suction nozzle 111 is formed on the atomizer housing 11, and the air inhalation channel 103 is arranged in the suction nozzle 111. The atomizer core 12 and the liquid storage cotton 123 are both arranged in the mounting cavity. The atomizer core 12 has an atomization channel 101, and the atomization channel 101 is connected to the air inhalation channel 103. The liquid storage cotton 123 is used to absorb the aerosol matrix flowing out of the liquid guide hole 301, and the atomizer core 12 is used to atomize the aerosol matrix absorbed on the liquid storage cotton 123. The atomizing core 12 includes a channel housing 121, a liquid-absorbing cotton 122 and a heating wire 13. The channel housing 121 is cylindrical and forms an atomizing channel 101. The liquid-absorbing cotton 122 is connected to the inner wall of the channel housing 121. The channel housing 121 is provided with a plurality of liquid inlet holes, and the liquid storage cotton 123 can be blocked at the liquid inlet holes. The aerosol matrix flowing out of the liquid guide hole 301 can be absorbed by the liquid storage cotton 123 to prevent the aerosol matrix from being sucked into the liquid storage cavity 201 from the liquid guide hole 301 when the compression cover 22 is switched to the release state. The liquid-absorbing cotton 122 is used to absorb the aerosol matrix in the liquid storage cotton 123, and the heating wire 13 is used to heat the liquid-absorbing cotton 122 to atomize the aerosol matrix in the liquid-absorbing cotton 122.

[0049] Optionally, the liquid storage cotton 123 is arranged around the atomizing core 12 to increase the volume of the liquid storage cotton 123, thereby increasing the amount of absorption of the eye. The liquid storage cotton 123 can block at least part of the liquid guide hole 301, so that the aerosol matrix flowing out of the liquid guide hole 301 can be directly absorbed by the liquid storage cotton 123 to avoid the loss of the aerosol matrix. Other liquid guide holes 301 that are not blocked by the liquid storage cotton 123 can facilitate the external atmosphere to enter the liquid storage space through the liquid guide hole 301 when the compression cover 22 is switched to the release state. When there are multiple liquid guide holes 301, the liquid storage cotton 123 can block part of the multiple liquid guide holes 301, or can block all the liquid guide holes 301. In an embodiment where a baffle 112 is provided, the liquid storage cotton 123 can block the liquid guide hole 301, or be located near the liquid guide hole 301, so as to achieve the absorption of the aerosol matrix.

[0050] Optionally, multiple liquid guide holes 301 can be interconnected, that is, multiple liquid guide holes 301 can be arranged together as strip-shaped holes, and the maximum width of the strip-shaped holes is less than 5 mm. In this way, it can ensure that the aerosol matrix does not flow out under a pressure-free state, and at the same time, the discharge amount of the aerosol matrix is ​​also increased. At this time, the liquid storage cotton 123 can block part or all of the strip-shaped holes.

[0051] In some embodiments, the liquid storage tank housing 21 is detachably connected to the atomization tank housing 11 , so that the liquid storage tank housing 21 can be replaced or the liquid storage tank housing 21 can be removed and the aerosol matrix can be injected into the liquid storage cavity 201 after the aerosol matrix is ​​used up.

[0052] See also Figure 2 and Figure 3 Optionally, the atomizer assembly 10 also includes an upper limit plate 17 and a lower limit plate 18 connected to the outside of the atomizer bin shell 11, and a limit hole 170 is provided on the upper limit plate 17. During installation, the compression cover 22 can be pressed to a compressed state first, so that the liquid storage bin shell 21 can be inserted between the upper limit plate 17 and the lower limit plate 18, and then the compression cover 22 can automatically reset to a released state after reaching a position relative to the limit hole 170. The top cover portion 221 on the compression cover 22 in the released state protrudes from the upper limit plate 17 to limit the position of the liquid storage assembly 20.

[0053] See also Figure 4 In some embodiments, the atomizer housing 11 further includes an air inlet channel 104 connected to the atomizer channel 101, and the air inlet channel 104 can be parallel to the atomizer channel 101 to reduce the width of the atomizer housing 11. The atomizer assembly 10 also includes an air regulating switch 15 and an air regulating baffle 14. The air regulating baffle 14 covers the air inlet of the air inlet channel 104 and is provided with at least one air inlet hole 140. The air regulating switch 15 is movably connected to the atomizer housing 11 and can move between a blocking position for blocking at least one air inlet hole 140 and a avoiding position for avoiding at least one air inlet hole 140. When the human mouth inhales through the suction nozzle 111, external gas enters the atomizer housing 11 through the air inlet hole 140, and enters the human oral cavity through the air inlet channel 104, the atomizer channel 101 and the suction channel 103 in turn.

[0054] Optionally, the air regulating baffle 14 is provided with two air inlet holes 140, and the air regulating switch 15 can move along the arrangement direction of the two air inlet holes 140. When the air regulating switch 15 is in the blocking position, the two air inlet holes 140 are blocked, and when the air regulating switch 15 is in the avoidance position, the two air inlet holes 140 are avoided. The air regulating switch 15 can stay between the blocking position and the avoidance position and only block one air inlet hole 140. When the air regulating switch 15 blocks the two air inlet holes 140, the atomizer is in a closed state, when the air regulating switch 15 blocks one air inlet hole 140, the atomizer is in a small gear, and when the air regulating switch 15 avoids the two air inlet holes 140, the atomizer is in a large gear. There is a damping force between the air regulating switch 15 and the atomization bin housing 11, so that the air regulating switch 15 can stay at any position.

[0055] Optionally, the gas regulating switch 15 may be provided with a gas regulating rod 16 , and the gas regulating rod 16 is used for a person to hold, so as to save more effort when turning the gas regulating switch 15 .
