Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomization technology, and in particular to an atomization component and an electronic atomization device. Background Technology
[0002] An electronic atomizing device is a device that heats and atomizes an atomizing matrix to generate an aerosol. Related electronic atomizing devices store the atomizing matrix in an internal storage chamber. The atomizing core absorbs the atomizing matrix and heats and atomizes it, causing the matrix to be gradually consumed. However, in cases where the storage chamber has a large capacity, the time required for the atomizing matrix to be completely consumed is long. Therefore, the atomizing matrix remains stationary in the storage chamber for an extended period. Especially since the composition of the atomizing matrix is more complex, it is prone to stratification after prolonged standing. Currently, when stratification occurs, the only solution is for the user to manually shake the product before use. However, manual shaking results in poor mixing (it is difficult to completely remix the atomizing matrix) and reduces user convenience, leading to a poor user experience. Utility Model Content
[0003] The technical problem to be solved by this application is to provide an improved atomizing component and electronic atomizing device, addressing at least one of the deficiencies mentioned in the background art.

[0005] In some embodiments, the cross-sectional area of the mixing section is smaller than the cross-sectional area of the motor body of the drive motor; and / or, the mixing section has an asymmetrical structure relative to the central axis of the output shaft of the drive motor; and / or, the geometric center of the cross-section of the mixing section does not coincide with the central axis of the output shaft of the drive motor.
[0006] In some embodiments, the cross-sectional shape of the mixing section includes a circular region and a semi-annular region, the center of the circular region coincides with the central axis of the output shaft of the drive motor, and the semi-annular region is connected to the circumferential periphery of the circular region.
[0007] In some embodiments, the atomizing assembly further includes a housing, a sealing unit, and an atomizing tube. The sealing unit and the atomizing tube are disposed inside the housing, and the sealing unit and the housing are sealed together. One end of the atomizing tube is mounted on the sealing unit, and the atomizing core is disposed inside the atomizing tube. The housing, the sealing unit, and the atomizing tube together define the storage cavity. The drive motor is mounted on the sealing unit.
[0008] In some embodiments, the sealing unit includes a bracket and a seal that fit together, the seal and the housing are sealed together, and the housing, the seal and the atomizing tube together define the storage cavity; the bracket is provided with a first mounting hole, the seal is provided with a second mounting hole, the drive motor extends into the first mounting hole and the second mounting hole respectively for fixing, and the drive motor and the second mounting hole are sealed together.
[0009] In some embodiments, the first mounting hole includes a first hole and a second hole that are connected to each other. The cross-sectional width of the first hole is smaller than the cross-sectional width of the second hole, thereby forming a stepped surface in the second hole.

[0030] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).
[0031] Please see Figure 1 and Figure 2 In some embodiments, an electronic atomizing device is provided, comprising a power supply unit and an atomizing component. The power supply unit and the atomizing component are electrically connected, providing a heating power source for the atomizing component. When energized, the atomizing component heats and atomizes the atomizing matrix, generating an aerosol / atomized vapor. Specifically, such as... Figure 2 As shown, the power supply unit may include battery cell 14.
[0032] Please see Figures 1 to 3 In some embodiments, an atomizing assembly is provided, comprising a storage chamber 10, an atomizing core 11, and a mixing assembly 2. The storage chamber 10 stores an atomizing matrix. Specifically, the atomizing matrix can be liquid. The atomizing core 11 is in liquid communication with the storage chamber 10; that is, the atomizing matrix in the storage chamber can flow to the atomizing core 11, which heats the atomizing matrix to generate aerosol / atomized vapor. A power supply unit is connected to the atomizing core 11 to provide heating power to the atomizing core 11.
[0033] The mixing component 2 includes a drive motor 21 and a mixing section 22. The drive motor 21 and the mixing section 22 are connected by a drive motor, and the mixing section 22 is driven to rotate. Specifically, the mixing section 22 is connected by a drive motor 211 to the output shaft 211 of the drive motor 21. The mixing section 22 is located inside the storage chamber 10 and can rotate under the drive of the drive motor 21 to stir and mix the atomized matrix. Furthermore, the mixing section 22 is eccentrically positioned relative to the output shaft 211 of the drive motor 21.
[0034] Since the mixing section 22 is located inside the storage chamber 10, and the drive motor 21 is connected to the mixing section 22, the mixing section 22 can be driven to rotate. Thus, after the atomized matrix is layered, the mixing section 22 can be used to mix the atomized matrix in the storage chamber 10 evenly. Furthermore, since the mixing section 22 is eccentrically positioned relative to the output shaft 211 of the drive motor 21, the eccentric stirring design can achieve a more efficient mixing effect.
[0035] like Figures 4 to 6 As shown, in some embodiments, the cross-sectional area of the mixing section 22 is smaller than the cross-sectional area of the motor body 212 of the drive motor 21. Lateral reference can be made to the CC direction in the figure. Furthermore, the mixing section 22 has an asymmetrical structure relative to the central axis D2 of the output shaft 211 of the drive motor 21. That is, the mixing section 22 has an irregular, asymmetrical structure. The geometric center D1 of the cross-section of the mixing section 22 does not coincide with the central axis D2 of the output shaft 211 of the drive motor 21. The geometric center D1 of the cross-section of the mixing section 22 refers to the centroid of the contour shape formed by the cross-sections of the mixing section 22. Figure 5 The diagram illustrates the point projection of the central axis D2 of the output shaft 211 of the drive motor 21 from a cross-sectional perspective. (See diagram for example.) Figure 5 and Figure 6 As shown, the geometric center D1 of the cross-section of the mixing section 22 is offset from the central axis D2 of the output shaft 211 of the drive motor 21, forming an eccentric structure. Based on this eccentric structure, the flow field generated by the mixing section 22 when rotating in the storage cavity 10 is asymmetrical, thereby achieving a more rapid and uniform mixing effect of the atomized matrix.
[0036] Specifically, such as Figure 6As shown, in some embodiments, the cross-sectional shape of the mixing section 22 includes a circular region 221 and a semi-annular region 222. The center of the circular region 221 coincides with the central axis D2 of the output shaft 211 of the drive motor 21, and the semi-annular region 222 is connected to the circumferential periphery of the circular region 221. Correspondingly, the mixing section 22 may include a circular portion and a semi-annular portion, which may be integrally formed or separately formed and then connected into a whole. That is, the area of the semi-annular region 222 is smaller than the cross-sectional area of the motor body 212 of the drive motor 21. Thus, when the mixing section 22 rotates within the storage cavity 10, it mainly relies on the rotational disturbance of the semi-annular portion to rapidly achieve a uniformly mixed state of the layered atomized matrix.
[0037] like Figure 2 and Figure 3 As shown, in some embodiments, the atomizing assembly further includes a housing 13, a sealing unit 3, and an atomizing tube 15. The sealing unit 3 and the atomizing tube 15 are disposed inside the housing 13. The sealing unit 3 and the housing 13 are sealed together. One end of the atomizing tube 15 is mounted on the sealing unit 3. The atomizing core 11 is disposed inside the atomizing tube 15. Specifically, the interior of the atomizing tube 15 defines an atomizing channel 17, and the atomizing core 11 is disposed within this atomizing channel 17. The housing 13 is provided with a mouthpiece 130, and the end of the atomizing tube 15 away from the sealing unit 3 is in fluid communication with the mouthpiece 130, so that the aerosol / atomized vapor in the atomizing channel 17 can flow out through the mouthpiece 130 for the user to inhale. The housing 13, the sealing unit 3, and the atomizing tube 15 together define a storage cavity 10. A drive motor 21 is mounted on the sealing unit 3. Specifically, the drive motor 21 and the sealing unit 3 are sealed together to prevent liquid in the storage cavity 10 from leaking out from the gap between the drive motor 21 and the sealing unit 3.
[0038] like Figure 2As shown, in some embodiments, the electronic atomizing device further includes a circuit board 16, which is connected to the drive motor 21 of the atomizing assembly via a wire 23. The circuit board 16 is located on the side of the sealing unit 3 away from the storage cavity 10. The circuit board 16 is connected to the atomizing core 11 and can control the on / off state of the atomizing core 11 through a control circuit, thereby controlling the working state of the atomizing core 11. Further, in some embodiments, a motor control circuit module is provided on the circuit board 16 for controlling the working state of the drive motor 21. The electronic atomizing device also includes an airflow sensor (not shown), which is communicatively connected to the circuit board 16. The airflow sensor is fluidly connected to the airflow channel, and the airflow channel is fluidly connected to the atomizing channel 17 where the atomizing core 11 is located. When the user inhales at the mouthpiece 130, it causes a change in air pressure inside the atomizing channel 17. The airflow sensor can capture the change in air pressure inside the atomizing channel 17 and convert it into an electrical signal, which is then sent to the circuit board 16. Therefore, the motor control circuit module can control the start, stop, rotation angle, and rotation speed of the drive motor 21 based on the air pressure changes within the atomization channel 17. These air pressure changes are generated by the user's inhalation action. Thus, the motor control circuit module can control the start, stop, rotation angle, and rotation speed of the drive motor 21 based on the user's inhalation action. For example, the motor control circuit module can be set to start the drive motor 21 based on the user's three inhalations within 5 seconds; the operating duration of each start of the drive motor 21 can be set to 1 minute, or another time. Therefore, when the drive motor 21 is connected to the circuit board 16 via the wire 23, the start and stop of the drive motor 21 can be automated as needed. Alternatively, in some other embodiments, a button can be designed on the outside of the housing 13, connected to the circuit board 16, allowing the user to manually control the start and stop of the drive motor 21 by triggering the button.
[0039] like Figure 2 , Figure 3 , Figures 7 to 9 As shown, in some embodiments, the sealing unit 3 includes a bracket 31 and a seal 32 that fit together. The seal 32 and the housing 13 are sealed together, and the housing 13, the seal 32, and the atomizing tube 15 together define the storage cavity 10. The bracket 31 has a first mounting hole 310, and the seal 32 has a second mounting hole 320. The drive motor 21 extends into the first mounting hole 310 and the second mounting hole 320 for fixation. Thus, the drive motor 21 is limited and fixed to the sealing unit 3 through the first mounting hole 310 and the second mounting hole 320. Furthermore, the drive motor 21 and the second mounting hole 320 are sealed together. For example, the motor body 212 of the drive motor 21 and the second mounting hole 320 may be interference-fitted. This prevents liquid in the storage cavity 10 from leaking from the gap between the drive motor 21 and the seal 32.
[0040] like Figure 3 and Figure 9 As shown, in some embodiments, a plurality of sealing rings 321 are protruding from the wall of the second mounting hole 320. The sealing rings 321 abut against the motor body 212 of the drive motor 21, thereby enhancing the sealing effect between the drive motor 21 and the second mounting hole 320.
[0041] like Figure 2 and Figure 9 As shown, in some embodiments, the bracket 31 further forms a mounting cavity 314, which communicates with the first mounting hole 310. Components such as the battery cell 14 and the liquid-absorbing component 18 are disposed within this mounting cavity 314. That is, on the one hand, the bracket 31 cooperates with the seal 32 to mount the drive motor 21; on the other hand, the bracket 31 also provides mounting space for other components (such as the battery cell 14). In some embodiments, the bracket 31 can be a plastic component; the seal 32 can be an elastic component such as a silicone component, a rubber component, or a silicone rubber component, and the seal is achieved by using elastic force and interference fit with the drive motor 21.
[0042] like Figure 3 and Figure 9 As shown, in some embodiments, the first mounting hole 310 includes a first hole position 311 and a second hole position 312 that are connected. The cross-sectional width of the first hole position 311 is smaller than the cross-sectional width of the second hole position 312, thereby forming a stepped surface 313 in the second hole position 312. The end of the drive motor 21 away from the mixing part 22 abuts against the stepped surface 313. Specifically, the lateral direction can be referred to... Figure 3 and Figure 9 In the CC direction. The cross-sectional width of the motor body 212 of the drive motor 21 is greater than the cross-sectional width of the first hole 311 and less than the cross-sectional width of the second hole 312. The end face of the motor body 212 of the drive motor 21 away from the output shaft 211 abuts against the stepped surface 313.
[0043] like Figure 3 , Figure 4 and Figure 9 As shown, in some embodiments, the mixing component 2 further includes a wire 23 connected to the end of the drive motor 21 away from the mixing section 22. The end of the wire 23 away from the drive motor 21 passes through the first hole 311. The end of the wire 23 away from the drive motor 21 is connected to the circuit board 16.
[0044] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention.
