DETAILED DESCRIPTIOIN OF EMBODIMENTS
[0012] In order to make the objective, the technical solutions and the advantages of the present invention be clearer, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings.
[0013] In order to describe the technical solutions provided in the present invention, the technical solutions are elaborated in detail with reference to the accompanying figures and the embodiments.
[0014] In accordance with the first aspect, an atomization device 100 is provided in the embodiments of the present invention. The atomization device 100 includes an atomization holder 10 and an atomization assembly 20. It is to be understood by the person of ordinary skill in the art that the atomization holder 10 is suitable for use within the atomization device 100, and the atomization assembly 20 is used to be mounted on the atomization holder 10. In other words, the atomization assembly 20 may be mounted within the atomization device 100 through the atomization holder 10.
[0015] The atomization holder 10 includes a holder body 1 and an adjustment part 2 matching with the holder body 1, where the holder body 1 includes a partition plate 11. When the holder body 1 is mounted inside the atomization device 100, the partition plate 11 may fit with an internal space of the atomization device 100 to separate a liquid storage chamber 101 and a liquid guiding chamber 102 formed inside the atomization device 100.
[0016] Referring to FIGS. 1, 2, and 3, the partition plate 11 is provided with at least two through holes 111 that pass through an upper surface and a lower surface of the partition plate 11. The adjustment part 2 is mounted on the holder body 1 and may control all through holes 111 to be in an open state or a closed state through displacement.
[0017] Referring to FIGS. 1, 2, and 3. In this case, all through holes 111 are in the closed state under the action of the adjustment part 2. Referring to FIGS. 7 and 8, in this case, all through holes 111 are in the open state under the action of the adjustment part 2.
[0018] Since the adjusting element 2 may displace relative to the holder body 1 and control the through holes 111 to be in different states through displacement, when the through holes 111 are in the open state by changing the position of the adjustment part 2, the matrix-for-forming-aerosols located in the liquid storage chamber 101 may flow into the liquid guiding chamber 102 through a through hole 111. Meanwhile, some of the gas located in the liquid guiding chamber 102 may flow into the liquid storage chamber 101 through another through hole 111 under the action of air pressure. At this moment, the liquid guiding channel is in an unblocked state. When all through holes 111 are in the closed state, the liquid guiding channel is in a closed state. Accordingly, a leakage risk of the atomization device 100 having this atomization holder 10 may be effectively reduced, and the user experience of the atomization device 100 may be improved. Most importantly, the design of at least two through holes 111 mentioned above allows at least one of the through holes 111 to balance air pressure when the through holes 111 are in the open state. The gas located in the liquid guiding chamber 102 may flow to the liquid storage chamber 101 under the action of air pressure, thereby maintaining a relatively stable pressure difference between the liquid storage chamber 101 and the liquid guiding chamber 102, which is conducive to increasing a flow rate of the matrix-for-forming-aerosols in the liquid storage chamber 101 through the through holes 111.
[0019] It should be appreciated that the gas located in the liquid guiding chamber 102 flows towards the liquid storage chamber 101 through an adjacent through hole 111 preferentially. Specifically, a through hole 111 which is arranged on the side closer to the liquid storage chamber 101 and forms bubbles facilitates the flow of gas from the liquid guiding chamber 102 to the liquid storage chamber 101. The other through holes 111, where no bubbles are formed, is used to facilitate a matrix-for-forming-aerosols in the liquid storage chamber 101 to flow towards the liquid guiding chamber 102.
[0020] The specific structure of the atomization holder 10, which is constituted of the holder body 1 and the adjustment part 2, will be elaborated below by taking the through holes 111 in a closed state By way of example.
[0021] The holder body 1 provided in the embodiments of the present invention includes a partition plate 11, a peripheral side plate 12, and a mounting part 13. As shown in FIG. 6, the partition plate 11 and the mounting part 13 are oppositely arranged, and the peripheral side plate 12 is configured to connect the partition plate 11 and the mounting part 13. The liquid guiding chamber 102 is formed between the partition plate 11, the peripheral side plate 12, and the mounting part 13, and the liquid storage chamber 101 is formed on a side of the partition plate 11 away from the mounting part 13. Certainly, in addition to the through holes 111, the partition plate 11 is further provided with a first mounting hole 112. Correspondingly, a second mounting hole 131 is provided at a position of the mounting part 13 corresponding to the first mounting hole 112. The atomization assembly 2 may be mounted on the holder body 1 through the first mounting hole 112 and the second mounting hole 131. A third mounting hole 132 is further provided on the mounting part 13, and the third mounting hole 132 is spaced apart from the second mounting hole 131. The adjustment part 2 may be connected to the mounting part 13 through the third mounting hole 132.
[0022] In the embodiment of the present invention, two through holes 111 are provided on the partition plate 11, and sizes and shapes of openings of the two through holes 111 are completely identical. Referring to FIG. 2, the two through holes 111 are arranged symmetrically. In other similar embodiments, the shape of the through holes 111 may be adjusted according to design requirements to ensure that the through holes 111 have the same opening size and different opening shapes. Alternatively, the through holes 111 may be adjusted such that these through holes 111 have different opening sizes while maintaining similar opening shapes. As an alternative, the number of through holes 111 may be further increased. For example, the number of through holes 111 is set to three, four, or even more. Multiple through holes 111 may be arranged to be distributed in a linear array, a circular array, or a rectangular array, etc.
[0023] It should be noted that the opening size of the aforesaid through hole 111 needs to be adaptively adjusted according to the physical properties such as viscosity and surface tension of the used matrix-for-forming-aerosols, so that the normal flow of the matrix-for-forming-aerosols located in the liquid storage chamber 101 is not affected.
[0024] When the atomization assembly 20 is mounted on the holder body 1 through the first mounting hole 112 and the second mounting hole 131, at least a part of the atomization assembly 20 is located within the liquid guiding chamber 102 and keeps a state of interconnecting with the liquid guiding chamber 102.
[0025] In some embodiments, the adjustment part 2 includes a rotating member 21. In this case, the adjustment part 2 may control opening or closing of all through holes 111 through rotational displacement.
[0026] Certainly, in other similar embodiments, the adjustment part 2 may also be positioned between the partition plate 11 and the mounting part 13. In this case, the adjustment part 2 may control opening or closing of the through holes 111 by making translating movement relative to the partition plate 11 or extending or retracting relative to the partition plate 11.
[0027] The structure of the adjustment part 2 is described hereinafter by describing the rotation manner of the adjustment part 2 relative to the partition plate 11.
[0028] Referring to FIGS. 1 and 4, the adjustment part 2 is a rotating member 21. The rotating member 21 is mounted on the holder body 1 through the third mounting hole 132 and abuts against a side surface of the partition plate 11 facing the mounting part 13. In this case, at least part of the rotating member 21 is located within the liquid guiding chamber 102.
[0029] The rotating member 21 has a rotating shaft to facilitate rotation around the axis, and controls the opening or the closing of all through holes 111 through the displacement generated by rotational movement. When the through holes 111 are in the closed state, referring to FIGS. 4 and 5, the through holes 111 are arranged to be directly opposite to the rotating member 21 along an axial direction of the rotating member 21. When the through holes 111 are in the open state, referring to FIGS. 7 and 8, the through holes 111 and the rotating member 21 are arranged to be distributed at intervals on a side surface facing the partition plate 11.
[0030] The aforesaid distributed at intervals refers to any of the following conditions: an orthogonal projection of the through hole 111 on the partition plate 11 along the axial direction of the rotating member 21 is spaced from, does not coincide with, or only partially coincides with an orthogonal projection of a surface of the rotating member 21 facing the partition plate 11 on the partition plate 11. Certainly, when the two orthogonal projections are partially coincident, it is necessary to ensure that the size of the non-coincident part meets the normal liquid feeding requirements of the matrix-for-forming-aerosols.
[0031] Referring to FIGS. 4 and 5. In this state, two through holes 111 are in a closed state. At this time, the matrix-for-forming-aerosols located in the liquid storage chamber 101 is stored within the liquid storage chamber 101, the risk of leakage of the matrix-for-forming-aerosols may be reduced to a certain extent. Referring to FIGS. 7 and 8, in this state, the through holes 111 are in an open state. At this time, the matrix-for-forming-aerosols located in the liquid storage chamber 101 may flow through the through holes 111 into the liquid guiding chamber 102. Meanwhile, the gas located in the liquid guiding chamber 102 may also flow into the liquid storage chamber 101 through at least one through hole 111 in the form of bubbles under the action of air pressure, thereby further improving a dripping rate of the matrix-for-forming-aerosols and achieving smooth dripping of the matrix-for-forming-aerosols. The above structure is conducive to improving the user experience of the atomization device 100 having the atomization holder 10.
[0032] The matrix-for-forming-aerosols within the liquid storage chamber 101 has the maximum capacity when it is initially used, while the liquid guiding chamber 102 is in an empty state (i.e., the liquid guiding chamber 102 is only filled with a certain amount of gas). After the through hole 111 is in an open state, with the continuous circulation of matrix-for-forming-aerosols and the gas, the matrix-for-forming-aerosols within the liquid storage chamber 101 gradually decreases, and the gas within the liquid guiding chamber 102 also gradually decreases.
[0033] Referring to FIG. 4, the part of the rotating member 21 that passes through the third mounting hole 132 and extends into the liquid guiding chamber 102 includes a first blocking part 211, a second blocking part 212, and a connecting part 213 for connecting the first blocking part 211 and the second blocking part 212. The first blocking part 211, the connecting part 213, and the second blocking part 212 are fixedly connected, and the first blocking part 211 and the second blocking part 212 are located on opposite sides of the connecting part 213 in a circumferential direction. The first blocking part 211 and the second blocking part 212 may be arranged to be opposite to the two through holes 111 and enclose the two through holes 111, respectively.
[0034] The partition plate 11 is further provided with a limiting hole 113, and the limiting hole 113 is located between the two through holes 111 arranged to be opposite to each other. The connecting part 213 passes through the limiting hole 113, and the connecting part 213 is precisely rotationally fitted with the limiting hole 113. Referring to FIGS. 4 and 5, the axes of the connecting part 213 and the limiting hole 113 coincide, and the axis of the connecting part 213 coincides with the axis of the rotating member 21. When the rotating member 21 rotates around the axis, the first blocking part 211 and the second blocking part 212, which are located on the two sides of the connecting part 213, rotate and make displacement relative to the two through holes 111.
[0035] Specifically, the axis of the limiting hole 113 coincides with the axis of the third mounting hole 132. In this case, the rotating member 21 may rotate around the axis thereof under the cooperation of the limiting hole 113 and the third mounting hole 132, thereby controlling opening and closing of the through holes 111.
[0036] In some embodiments, the rotating member 21 may be arranged to continuously rotate relative to the holder body 1. When the first blocking part 211 just encloses a through hole 111, the second blocking part 212 arranged opposite to the first blocking part 211 may just enclose the other through hole 111. When the first blocking part 211 just remains staggered with the through hole 111, the second blocking part 212 arranged opposite to the first blocking part 211 also remains staggered with the through hole 111.
[0037] In other similar embodiments, the rotating member 21 is provided with a limiting protrusion 2102, and the corresponding position of the mounting part 13 is provided with a limiting member 133 that matches with the limiting protrusion 2102. The limiting member 133 is used to limit a rotation angle of the rotating member 21 relative to the holder body 1.
[0038] The limiting member 133 may be utilized to limit the rotation range and the rotation angle of the rotating member 21 so as to improve the precision of rotation of the rotating member 21, which is conducive to preventing misalignment of the rotating member 21 relative to the through hole 111 after multiple rotations.
[0039] Specifically, the rotating member 21 is constrained to perform reciprocal rotation within a 180° range relative to the holder body 1, to achieve opening or closing of the through hole 111. Alternatively, the rotating member 21 may perform reciprocal rotation within a 90° range relative to the holder body 1, to achieve opening or closing of the through hole 111.
[0040] The specific structures of the limiting protrusion 2102 and the limiting member 133 are described below.
[0041] The limiting protrusion 2102 may be formed at an end of the rotating member 21 away from the partition plate 11. Alternatively, the limiting protrusion 2102 may be convexly arranged in an area contacting an inner side wall of the third mounting hole 132.
[0042] Exemplarily, referring to FIGS. 3 and 7, the limiting protrusion 2102 protrudes from a circumferential side wall of the end of the rotating member 21 away from the partition plate 11. The limiting member 133 has a first contact wall 1331 and a second contact wall 1332 that comes into contact with the limiting protrusion 2102, the first contact wall 1331 and the second contact wall 1332 are oppositely arranged. When the limiting protrusion 2102 comes into contact with the first contact wall 1331, the through hole 111 is in a closed state. When the limiting protrusion 2102 comes into contact with the second contact wall 1332, the through hole 111 is in an open state.
[0043] During the rotation of the rotating member 21, the limiting protrusion 2102 may have displacement relative to the limiting member 133 and has the following three states: the limiting protrusion 2102 is in contact with the first contact wall 1331, the limiting protrusion 2102 is in contact with the second contact wall 1332, the limiting protrusion is positioned between the first contact wall 1331 and the second contact wall 1332 without contacting with either of the first contact wall 1331 and the second contact wall 1332. When the limiting protrusion 2102 moves relative to the limiting member 133 and comes into contact with a contact wall, a force that resists further movement of the limiting protrusion 2102 in the original rotational direction is generated at the contact point, thereby preventing the rotating member 21 from continuing to rotate. The same principle applies during reverse rotation.
[0044] Therefore, under the constraints of the first contact wall 1331 and the second contact wall 1332, the rotating member 21 may be controlled to perform reciprocal rotation within a certain angular range.
[0045] In order to enhance the stability of the rotation process, in some embodiments, the number of the limiting protrusions 2102 is set to two, and the two limiting protrusions 2102 are arranged oppositely. Correspondingly, the number of limiting members 133 configured to match with the limiting protrusions 2102 for achieving limiting function is also two, and the two limiting members 133 are arranged to correspond to the two limiting protrusions 2102 in one-to-one correspondence manner.
[0046] In this embodiment, the limiting member 133 is configured as a limiting notch 13301. A portion of the surface of the mounting part 13 on the side away from the partition plate 11 is recessed inwardly, thereby forming the limiting notch 13301. The first contact wall 1331 and the second contact wall 1332 are respectively arranged on the two sides of the limiting notch 13301 in the length direction, and the central angle corresponding to the limiting notch 13301 is in a range of 60°~120°.
[0047] Referring to FIGS. 3 and 7, the central angle corresponding to the limiting notch 13301 is 90°, which may restrict the reciprocating rotation of the rotating member 21 within a 90° range. In other similar embodiments, the central angle may be adjusted to 60°, 70°, 80°, 90°, 100°, 110°, 120°, etc., according to design requirements. Thus, the rotating member 21 may effectively control opening or closing of the through hole 111.
[0048] Specifically, the limiting notch 13301 also has a third contact wall connecting the first contact wall 1331 and the second contact wall 1332. An extension direction of the third contact wall coincides with a rotational path of a rotating protrusion. When the rotating protrusion displaces relative to the limiting notch 13301, a side surface of the rotating protrusion facing the partition plate 11 may fit with the third contact wall in a sliding manner.
[0049] In other similar embodiments, the limiting member 133 may also be designed as a limiting protrusion. A portion of the surface of the mounting part 13 away from the partition plate 11 protrudes and forms the limiting protrusion. The first contact wall 1331 and the second contact wall 1332 are respectively arranged on two sides of the limiting protrusion in the length direction.
[0050] For example, when the number of through holes 111 is three, the rotating member 21 may be restricted to perform reciprocal rotation within a range of 0°~60° or 0°~120° relative to the holder body 1. Accordingly, opening or closing of the through holes 111 is achieved.
[0051] Referring to FIG. 4, in order to further improve the sealing effect of the rotating member 21 on the through hole 111, in some embodiments, a side of the rotating member 21 which comes into contact with the partition plate 11 is provided with an elastic sealing ring 2101, the rotating member 21 may abut against the partition plate 11 through the elastic sealing ring 2101.
[0052] Specifically, multiple elastic sealing rings 2101 are located on the surface of the rotating member 21 facing the partition plate 11, the number of the elastic sealing rings 2101 is two, the two elastic sealing rings 2101 are respectively formed on the first blocking part 211 and the second blocking part 212.
[0053] Each elastic sealing ring 2101 is configured to seal the through hole 111. In the axial direction of the rotating member 21, when the side of the rotating member 21 facing the partition plate 11 overlaps with the through hole 111, an orthographic projection of the through hole 111 is located exactly within the orthographic projection of the elastic sealing ring 2101. In this case, the elastic sealing ring 2101 abuts against the side wall of the partition plate 11 facing the rotating member 21 and generates recoverable elastic deformation, a sealed environment is formed between the elastic sealing ring 2101 and the partition plate 11. The through hole 111 located inside the elastic sealing ring 2101 is inevitably in a closed state.
[0054] In order to facilitate mounting of the elastic sealing ring 2101, in some embodiments, the rotating member 21 includes a fixedly connected main body and an elastic part. The elastic part is located at least on the surface of the rotating member 21 facing the partition plate 11, and the main body is fixedly connected to the elastic part. The elastic sealing ring 2101 is formed on the elastic part. For example, the rotating member 21 may be arranged to include a main body and an elastic part which are fixedly connected in the axial direction thereof. The elastic part is located on the side of the rotating member 21 facing the partition plate 11.
[0055] Referring to FIGS. 4 and 5, a sealing ring 3 is further provided in the third mounting hole 132 which is disposed on the holder body 1. The sealing ring 3 is configured to seal a assembly clearance between the third mounting hole 132 and the rotating member 21, thereby preventing the matrix-for-forming-aerosols that flows into the liquid guiding chamber 102 from leaking through the assembly clearance formed between the third mounting hole 132 and the rotating member 21.
[0056] Specifically, a groove is formed in the third mounting hole 132, a part of the sealing ring 3 is located within the groove and a part of the sealing ring 3 protrudes relative to the groove. When the rotating member 21 is mounted on the holder body 1 through the third mounting hole 132, the rotating member 21 compresses the sealing ring 3, thereby causing the sealing ring 3 to generate recoverable elastic deformation. Accordingly, a sealed environment between the sealing ring 3, the groove, and the rotating member 21 is formed.
[0057] In some embodiments, the number of the sealing rings 3 is at least two, and the two sealing rings 3 are arranged at intervals along the axial direction of the rotating member 21.
[0058] In some embodiments, the atomization holder 10 further includes a driving part 4. The driving part 4 has an output shaft 41. The output shaft 41 is connected to the adjustment part 2 and is configured to drive the adjustment part 2 to make displacement.
[0059] Referring to FIG. 9, the adjustment part 2 includes the rotating member 21. The driving part 4 is located on the side of the mounting part 13 away from the partition plate 11, the output shaft 41 of the driving part 4 is connected to the connecting part 213 of the rotating member 21, and is used to drive the rotating member 21 to rotate through the connecting part 213.
[0060] It should be noted that the axis of the aforesaid output shaft 41 coincides with the axis of the limiting hole 113 disposed on the partition plate 11. The rotating member 21 is mounted on the output shaft 41 of the driving part 4 and may rotate around the axis under the driving of the driving part 4, thereby controlling opening or closing of all through holes 111.
[0061] Specifically, the driving part 4 may be a stepper motor. The stepper motor may achieve high-precision positioning and motion control, may effectively drive the rotating member 21 and precisely control the rotation angle and the rotation range of the rotating member 21. Alternatively, in other similar embodiments, the driving part 4 may also be configured as a stepper reduction motor. Compared to the stepper motor, the stepper reduction motor incorporates a reduction mechanism, and thus may provide greater torque at lower rotational speeds. Accordingly, the operational precision and the stability of the driving part 4 is further improved, and vibration and noise generated during operation of the stepper motor are reduced.
[0062] It should be appreciated that in the atomization device 100 provided in the embodiments of the present invention, the atomization holder 10 of the atomization device 100 may control the through holes 111 through the at least two through holes 111 arranged on the partition plate 11 and the adjustment part 2 that may generate displacement relative to the through holes 111, such that the through holes 111 can be switched between the open state and the closed state, thereby improving the liquid leakage problem of the matrix-for-forming-aerosols to a certain extent and enhancing the user experience.
[0063] Referring to FIGS. 10 and 11, the atomization device 100 may include an atomization holder 10 and an atomization assembly 20. The atomization device 100 may further include an upper housing 30, a lower housing 40, and a power supply component 50. The structure of the atomization holder 10 can refer to the above descriptions. The atomization holder 10 mainly includes a holder body 1 and an adjustment part 2. The holder body 1 has a partition plate 11. When the holder body 1 is fixedly connected to the upper housing 30, the partition plate 11 may match with the upper housing 30 and divide an interior of the atomization device 100 into a liquid storage chamber 101 and a liquid guiding chamber 102. The liquid storage chamber 101 and the liquid guiding chamber 102 are arranged in a stacked manner along the height direction of the atomization device 100, and the liquid storage chamber 101 is located above the liquid guiding chamber 102. The partition plate 11 of the holder body 1 is provided with a through hole 111, which is interconnected with the liquid storage chamber 101 and the liquid guiding chamber 102. The adjustment part 2 is mounted on the holder body 1 and may control opening or closing of the through hole 111 through displacement.
[0064] The atomization holder 10 can not only be used to match with the upper housing 30 so as to form the liquid storage chamber 101 and the liquid guiding chamber 102, but also realize separation and sealing of the two different chambers through the adjustment part 2. When the two chambers are in an interconnected state, the effect of rapid flow of the matrix-for-forming-aerosols from the liquid storage chamber 101 to the liquid guiding chamber 102 may be achieved.
[0065] Specifically, the adjustment part 2 is mounted on the side of the holder body 1 away from the liquid storage chamber 101 and partially located within the liquid guiding chamber 102. The adjustment part 2 may adjust the through hole 111 to different states such as open state or closed state by rotating around its own axis by a certain angle.
[0066] The liquid storage chamber 101 is used to store a certain amount of matrix-for-forming-aerosols, and the liquid guiding chamber 102 is filled with an appropriate amount of gas. The number of through holes 111 located on the partition plate 11 is at least two, and these through holes 111 interconnect the upper surface and the lower surface of the partition plate 11. When the through holes 111 are in an open state, the liquid storage chamber 101 and the liquid guiding chamber 102, which are located on the upper side and the lower side of the partition plate 11 respectively, are interconnected. The matrix-for-forming-aerosols located in the liquid storage chamber 101 may flow to the liquid guiding chamber 102 through one through hole 111. Correspondingly, the gas located in the liquid guiding chamber 102 may also flow to the liquid storage chamber 101 through another through hole 111. Referring to FIGS. 11 and 12, when the through holes 111 are in a closed state, the liquid storage chamber 101 and the liquid guiding chamber 102 are disconnected. In this case, the matrix-for-forming-aerosols located in the liquid storage chamber 101 cannot flow to the liquid guiding chamber 102 through the through hole 111, which is conducive to improving the leakage problem of the matrix-for-forming-aerosols.
[0067] The atomization assembly 20 is mounted on the holder body 1. The holder body 1 may be fixedly connected to the upper housing 30, and the holder body 1 and the upper housing 30 are enclosed to form the liquid storage chamber 101 and the liquid guiding chamber 102, which are separated by the partition plate 11. Additionally, a mouthpiece 301 that interconnects with the atomization assembly 20 is provided on a position of the upper housing 30 corresponding to the atomization assembly 20. One end of the mouthpiece 301 is orientated towards the external environment, while the other end of the mouthpiece 301 is connected to the atomization assembly 20. The aerosol formed at the atomization assembly 20 may be inhaled by the user through the mouthpiece 301 under the driving of airflow.
[0068] Referring to FIGS. 12 and 13, the part of the atomization assembly 20 located within the liquid guiding chamber 102 is arranged to be spaced apart from the part of the adjustment part 2 located within the liquid guiding chamber 102. The atomization assembly 20 includes an atomizing tube 201 and a heating element 202. The heating element 202 is located within the atomizing tube 201, and a plurality of liquid inlet holes 2011 are provided on the atomizing tube 201. When the atomization assembly 20 is mounted on the holder body 1, at least a part of the atomizing tube 201 is located within the liquid guiding chamber 102. In this case, the heating element 202 may keep interconnected with the liquid guiding chamber 102 through the liquid inlet holes 2011. The matrix-for-forming-aerosols flowing into the liquid guiding chamber 102 through the through hole 111 may flow through the liquid inlet holes 2011 to the heating element 202 and generate aerosols under the heating effect of the heating element 202.
[0069] In the atomization device 100 provided in the embodiments of the present invention, the atomization holder 10 and the atomizing tube 201 having the liquid inlet holes 2011 may be used to improve the problem that the matrix-for-forming-aerosols is prone to leakage without affecting the flow of the matrix-for-forming-aerosols to the atomization assembly 20. Accordingly, the user experience of the atomization device 100 is enhanced.
[0070] Specifically, the number of the aforementioned liquid inlet holes 2011 may be one, two, or even more. As shown in FIG. 13, when the number of liquid inlet holes 2011 is at least two, all of the plurality of liquid inlet holes 2011 are evenly distributed and spaced apart from each other around the circumferential side wall of the atomizing tube 201.
[0071] In some embodiments, some liquid guide members are also filled between the heating element 202 and the atomizing tube 201. The liquid guide members have the function of adsorbing matrix-for-forming-aerosols, and may adsorb the matrix-for-forming-aerosols flowing into the atomizing tube 201 through the liquid inlet holes 2011 and deliver the matrix-for-forming-aerosols to the heating element 202.
[0072] Exemplarily, the liquid guide member may be prepared from any one or more of the materials including organic cotton, glass fiber, and ceramic fiber. Thus, it is ensured that the liquid guide member has good adsorption and delivery performance for matrix-for-forming-aerosols, and may continuously adsorb and delivery the matrix-for-forming-aerosols to the heating element 202, thereby ensuring a continuous and stable supply of matrix-for-forming-aerosols to the heating element 202.
[0073] The delivery of the matrix-for-forming-aerosols within the liquid guiding element may be either directional or non-directional, which depends on the material.
[0074] Referring to FIGS. 10 and 11. The upper housing 30 is further provided with a mouthpiece 301. When the upper housing 30 is fixedly connected to the holder body 1, the mouthpiece 301 may be arranged to be directly opposite to the atomization assembly 20 mounted on the holder body 1 and maintain interconnected. The aerosols formed at the atomization assembly 20 may flow out of the atomization device 100 along the mouthpiece 301, under suction effect.
[0075] Referring back to FIG. 10 and FIG. 11, the lower housing 40 is located on the side of the holder body 1 away from the liquid storage chamber 101, and the lower housing 40 and the holder body 1 may be enclosed to form an accommodating chamber 103. The power supply component 50 is located inside the accommodating chamber 103. The power supply component 50 is electrically connected with the atomization assembly 20 and is at least used to provide electrical energy to the heating element 202.
[0076] In some embodiments, the atomization device 100 includes a driving part 4. The adjustment part 2 needs to be driven by the driving part 4 to make displacement. Referring to FIG. 11, the driving part 4 is arranged within the accommodating chamber 103 and is electrically connected to the power supply component 50.
[0077] In some embodiments, the atomization device 100 further includes a control unit electrically connected to the driving part 4 and configured for controlling an operating state of the driving part 4, such as controlling the driving part 4 to rotate in a forward direction, controlling the driving part 4 to rotate in a reverse direction, controlling the driving part 4 to stop operation, etc.
[0078] The control unit may be a PCB board (Printed Circuit Board) which includes a processor. The processor may be a central processing unit (CPU). Alternatively, the processor may also be other general-purpose processor, microcontroller, digital signal processor (DSP), application specific integrated circuits (ASIC), field-programmable gate array (FPGA), programmable logic controller (PLC), discrete gate or transistor logic device, discrete hardware component, etc. The general-purpose processor may be a microprocessor. Alternatively, the general-purpose processor may also be any conventional processor.
[0079] In addition to the aforesaid processor, the control unit may also include a memory and a computer program stored in the memory and executable by the processor, such as a program for controlling the driving part 4 to perform operation or stop operation. The processor may execute the computer program so as to control the interconnection and disconnection between the liquid storage chamber 101 and the liquid guiding chamber 102 by controlling the action of the driving part 4.
[0080] In some embodiments, the upper housing 30 and the lower housing 40 may directly constitute the housing of the atomization device 100 through mutual splicing, alternatively, the upper housing 30 and the lower housing 40 merely constitute a part of the housing of the atomization device 100. External ambient air may enter the atomization device 100 through an air inlet arranged at a certain position on the lower housing 40 (the arrangement of the position of the air inlet has been disclosed in related technologies and will not be repeatedly elaborated here). After flowing through the atomization assembly 20, the air carries a certain amount of aerosols and flows out through the mouthpiece 301 formed on the upper housing 30.
[0081] Referring to FIGS. 14-26, an atomization device is further provided in the embodiments of the present invention. The atomization device includes an atomizer 100'.
[0082] The atomizer 100' of the atomization device provided by the present invention is part of a refillable atomization device. The atomizer 100' may be detachably connected to a power supply device 500 that matches the atomizer 100', the atomizer 100' and the power supply device 500 are assembled into a complete atomization device. The atomizer 100' may store matrix-for-forming-aerosols and heat and atomize it to generate aerosols. The atomizer 100' has a corresponding airway structure, the airflow mixes with the aerosols and flows to the mouthpiece structure 11' to be inhaled.
[0083] For the convenience of description, a height direction of the atomizer 100' and the atomization device is defined as the first direction, a width direction of the atomizer 100' and the atomization device is defined as the second direction, and a thickness direction of the atomizer 100' and the atomization device is defined as the third direction. The same applies to the subsequent embodiments. Arrow F1 represents the first direction, arrow F2 represents the second direction, and arrow F3 represents the third direction.
[0084] Some embodiments of the atomizer and the atomization device provided by the present invention are described below with reference to the accompanying drawings.
[0085] An atomization device is provided in some embodiments of the present invention, the atomization device includes an atomizer 100'. As shown in FIGS. 14, 15, and 16, the atomizer 100' includes an atomizer housing 1', a support assembly 2, an adjustment structure 3, and an atomization core assembly 4. The atomizer housing 1' is used as an outer housing, at least part of the atomization core assembly 4, the adjustment structure 3, and the support assembly 2 are arranged inside the atomizer housing 1'. In the first direction, one end of the atomizer housing 1' has a mouthpiece structure 11', and the other end of the atomizer housing 1' is an open structure. When the atomizer 100' is assembled and used with the power supply device, an end of the atomizer housing 1 away from the mouthpiece structure 11' may be connected to the power supply device. The support assembly 2 extends into the atomizer housing 1' from the end away from the mouthpiece structure 11' and is detachably connected to the atomizer housing 1'. A side wall of the support assembly 2 is in sealing engagement with the inner side wall of the atomizer housing 1'. The support assembly 2 and the inner wall surface of the atomizer housing 1' are enclosed to form a first chamber 12' for storing matrix-for-forming-aerosols. The support assembly 2 has an airway structure 211, and the airway structure 211 is connected to the mouthpiece structure 11'. A second chamber 212 is formed inside the support assembly 2, and the second chamber corresponds to the first chamber 12'. At least a part of the atomization core assembly 4 is arranged in the second chamber 212, and the atomization core assembly 4 is interconnected with the airway structure 211. The adjustment structure 3 is arranged at the junction between the first chamber 12' and the second chamber 212, and the adjustment structure 3 may be rotated to allow the first chamber 12' and the second chamber 212 to be interconnected or blocked. When the first chamber 12' and the second chamber 212 are interconnected, the matrix-for-forming-aerosols in the first chamber 12' may enter the second chamber 212, and the atomization core assembly 4 may heat the matrix-for-forming-aerosols in the second chamber 212 to atomize the matrix-for-forming-aerosols and generate aerosols. The aerosols may flow through the airway structure 211 to the mouthpiece structure 11' under the action of airflow.
[0086] It should be appreciated that in existing atomization devices, the liquid storage chamber and the liquid guiding channel connecting the atomizing core are usually directly interconnected, or interconnected through a disposable opening and closing structure. The liquid guiding channel cannot be closed automatically when being in a non-use state. Accordingly, liquid leakage is prone to occur.
[0087] According to the atomizer in this embodiment, through structural improvement and optimization, an independently arranged dual-chamber structure is adopted. Interconnection or blocking between the two chambers is achieved by performing rotation operation of the adjustment structure. Corresponding adjustment may be performed according to different usage needs, the risk of liquid leakage is effectively reduced. Moreover, operation may be performed automatically, the need for manual screwing and other operations are unnecessary. It is convenient to use the atomizer, which is conducive to improving the user experience.
[0088] It should be noted that, in practical application, the first chamber 12' and the second chamber 212 are not limited to the structure in which the first chamber 12' and the second chamber 212 are spaced apart in the first direction as shown in FIG. 16. The first chamber 12' and the second chamber 212 may also be spaced apart in the second direction or the third direction. Correspondingly, the direction of the rotational axis of the adjustment structure 3 is not limited to the direction along the first direction, the direction of the rotational axis of the adjustment structure 3 may be set according to the relative position of the first chamber 12' and the second chamber 212. In addition, the adjustment structure 3 may be a self-drive mechanism. Alternatively, the adjustment structure 3 may be driven by an external drive mechanism (e.g., the drive mechanism provided in the matched power supply device).
[0089] In some embodiments of the present invention, as shown in FIGS. 16, 17, and 18, in the atomizer 100', the first chamber 12' and the second chamber 212 are arranged at intervals in the first direction, the first chamber 12' is located near the mouthpiece structure 11' and the second chamber 212 is located on the side of the second chamber 212 away from the mouthpiece structure 11'. Correspondingly, a liquid guiding chamber 224 is also formed inside the support assembly 2. A first connecting hole 213 is provided on the chamber wall of the liquid guiding chamber 224 facing the first chamber 12', and a second connecting hole 2231 is provided on the chamber wall of the liquid guiding chamber 224 facing the second chamber 212. The adjustment structure 3 is arranged inside the liquid guiding chamber 224, and the adjustment structure 3 is in sealing engagement with the inner wall surface of the liquid guiding chamber 224. The liquid guiding chamber 224 has a first adjustment position corresponding to the first connecting hole 213 and the second connecting hole 2231. The adjustment structure 3 may rotate inside the liquid guiding chamber 224. When the adjustment structure 3 rotates to the first adjustment position, the first connecting hole 213 and the second connecting hole 2231 are opened, and the first chamber 12' and the second chamber 212 are interconnected. When the adjustment structure 3 rotates to a position where the first connecting hole 213 and / or the second connecting hole 2231 are blocked, the first connecting hole 213 and the second connecting hole 2231 are blocked. Correspondingly, the first chamber 12' and the second chamber 212 are in a closed state.
[0090] Since the first direction is the height direction of the atomizer 100', under normal condition, the first chamber 12' is located above the second chamber 212. When the first chamber 12' is interconnected with the second chamber 212, the matrix-for-forming-aerosols may flow towards the second chamber 212 under the action of gravity.
[0091] In a specific implementation manner, as shown in FIGS. 18, 19, and 20, the adjustment structure 3 includes a rotating member 31, a blocking piece 32, and a first sealing piece 33. The rotating member 31 is rotatably connected to the inner wall surface of the liquid guiding chamber 224 in the first direction, and the rotating member 31 is provided with a rotating shaft 311 extending along the first direction. The rotating shaft 311 of the rotating member 31 is circumferentially connected to the blocking piece 32, which faces the side wall of the liquid guiding chamber 224 and is provided with a liquid guiding channel 321. The blocking piece 32 may rotate with the rotating member 31. When the liquid guiding channel 321 rotates to a first adjustment position, the first connecting hole 213 and the second connecting hole 2231 are interconnected. The first sealing piece 33 is sleeved on the outer surface of the blocking piece 32, the first sealing piece 33 is in a sealing engagement with the inner wall surface of the liquid guiding chamber 224, thereby enabling the first connecting hole 213 and / or the second connecting hole 2231 to be blocked. Accordingly, the matrix-for-forming-aerosols is prevented from leaking into the second chamber 212 through gaps.
[0092] By way of specific example, as shown in FIGS. 19, 20, 21, and 22, an outer surface of the first sealing piece 33 facing the second connecting hole 2231 is provided with a sealing rib 331. The sealing rib 331 is a closed structure that fits to the shape of the second connecting hole 2231, and the sealing rib 331 is spaced apart from the liquid guiding channel 321 in the circumferential direction of the rotating member 31. When the sealing rib 331 rotates to the first adjustment position of the liquid guiding chamber 224, the sealing rib 331 may abut against a contour edge of the second connecting hole 2231, thereby completely blocking the second connecting hole 2231 to avoid gap. Accordingly, a closed state between the first connecting hole 213 and the second connecting hole 2231 is maintained.
[0093] Certainly, in a practical application, a sealing rib 331 may also be provided on a side of the first sealing piece 33 facing the first connecting hole 213. Due to this arrangement, when the sealing rib 331 rotates to the first adjustment position of the liquid guiding chamber 224, the sealing rib 33 may abut against the contour edge of the first connecting hole 213, thereby blocking the first connecting hole 213. Alternatively, the sealing rib 331 may also be provided on the side of the first sealing piece 33 facing the first chamber 12' and the side facing the second chamber 212, thereby simultaneously blocking the first connecting hole 213 and the second connecting hole 2231.
[0094] In addition, it should be noted that, as shown in the examples of FIG. 20, FIG. 21 and FIG. 22, the liquid guiding chamber 224 is a cylindrical chamber. The blocking piece 32 may include two fan-shaped structures symmetrically arranged on the two sides of the rotating shaft 311. The first sealing piece 33 may be a fan-shaped sealing sleeve made of silicone material which is sleeved on the outer surface of the blocking piece 32 to fit with the liquid guiding chamber 224. The first sealing piece 33 may adopt an integrated structure as shown in FIG. 22, that is, a sealing sleeve having two fan-shaped structures simultaneously, and is provided with a through hole to be passed through by the rotating shaft 311. Certainly, the first sealing piece 33 may also adopt a split structure sleeved on different fan-shaped structures of the blocking piece 32, respectively. In addition, the specific dimensions of the blocking piece 32 may be set according to the actual situation.
[0095] In some embodiments of the present invention, as shown in FIGS. 16 to 20, the support assembly 2 includes a first support member 21, a second support member 22, and a support base 23. The first support member 21, the second support member 22, and the support base 23 are sequentially arranged in a direction away from the mouthpiece structure 11' along the first direction. Moreover, the first support member 21, the second support member 22, and the support base 23 are in sealing engagement with the inner side wall of the atomizer housing 1'. The side of the first support member 21 facing the mouthpiece structure 11' and the inner wall surface of the atomizer housing 1' are enclosed to form the first chamber 12'. One end of the airway structure 211 is connected to the mouthpiece structure 11', and the other end of the airway structure 21 is connected to the first support member 21. A side of the second support member 22 facing the mouthpiece structure 11' and the first support member 21 are enclosed to form the second chamber 212 and the liquid guiding chamber 224. The second chamber 212 corresponds to the mouthpiece structure 11'. The liquid guiding chamber 224 is located within the second chamber 212 and is located on one side of the atomization core assembly 4 in the second direction. The support base 23 is detachably connected to the side of the second support member 22 away from the mouthpiece structure 11'. The support base 23 and the second support member 22 are enclosed to form an air guiding chamber 231, and the air guiding chamber 231 corresponds to the second chamber 212 in the first direction. The support base 23 is provided with an air inlet hole for external air to flow into the air guiding chamber 231. The atomization core assembly 4 is arranged in the second chamber 212 along the first direction, and one end of the atomization core assembly 4 is in sealing engagement with the airway structure 211, and the other end of the atomization core assembly 4 penetrates into the air guiding chamber 231. Thus, air in the air guiding chamber 231 is allowed to enter the atomization core assembly 4. The atomization core assembly 4 is in sealing engagement with the second support member 22 to prevent the matrix-for-forming-aerosols in the second chamber 212 from flowing into the air guiding chamber 231. The air guiding chamber 231 is provided with a first liquid absorbing part 234 (e.g., liquid absorbing cotton) for adsorbing condensed liquid generated by the atomization core assembly 4. The air inlet hole 232 on the support base 23 extends inwards along the first direction and penetrates through the first liquid absorbing part 234, such that the inner port of the air inlet hole 232 is higher than the first liquid absorbing part 234. Accordingly, condensed liquid is prevented from leaking out through the air inlet hole 232.
[0096] By providing the first support member 21, the second support member 22, and the support base 23 which are split from each other, the support assembly 2 may be assembled as a whole through detachable connection. Thus, manufacturing difficulty of the support base 23 may be reduced, assembling of the support base 23 is facilitated, which is conducive to improving a production efficiency.
[0097] In a specific example, as shown in FIGS. 21, 22, 23, and 24, in the support assembly 2, a side of the second support member 22 facing the first support member 21 is provided with a liquid guiding groove 223. Specifically, the liquid guiding groove 223 is a cylindrical groove and an opening of the liquid guiding groove 223 faces the first support member 21. The liquid guiding groove 223 abuts against the first support member 21, and the liquid guiding groove 223 and the first support member 21 are enclosed to form a liquid guiding chamber 224. The abutting point between the liquid guiding groove 223 and the first support member 21 is sealed with a second sealing piece 242. A bottom wall of the liquid guiding groove 223 is provided with a first limiting structure 2232, while the adjustment structure 3 is provided with a second limiting structure 312. The second limiting structure 312 is arranged to correspond to the first limiting structure 2232. During the rotation of the adjustment structure 3, the abutment between the second limiting structure 312 and the first limiting structure 2232 may limit the rotation of the adjustment structure 3.
[0098] Specifically, as shown in the examples in FIGS. 23 and 24, the first limiting structure 2232 is located on a bottom wall of the liquid guiding groove 223, and the first limiting structure 2232 is an arc-shaped protrusion structure. Correspondingly, the second limiting structure 312 is located at the end of the adjustment structure 3 facing the bottom wall of the liquid guiding groove 223, and the second limiting structure 312 is an arc-shaped groove structure corresponding to the arc-shaped protrusion structure. The extension directions of the arc-shaped protrusion structure and the arc-shaped groove structure are consistent with a rotational trajectory of the adjustment structure 3. The adjustment structure 3 may perform reciprocal rotation in a circumferential direction. The arc-shaped protrusion structure and the arc-shaped groove structure abut at any end in the circumferential direction, thereby forming rotational limit for the adjustment structure 3. When the adjustment structure 3 rotates to a position where the arc-shaped protrusion structure abuts at one end of the arc-shaped groove structure, the first connecting hole 213 and the second connecting hole 2231 are fully opened. When the adjustment structure 3 rotates to a position where the arc-shaped protrusion structure abuts at the other end of the arc-shaped groove structure, the first connecting hole 213 and / or the second connecting hole 2231 is / are fully closed.
[0099] By way of specific example, two or more first limiting structures 2232 are symmetrically arranged on the bottom wall of the liquid guiding groove 223. Correspondingly, the adjustment structure 3 is also provided with two or more second limiting structures 312 corresponding to the first limiting structures 2232.
[0100] By way of specific example, as shown in FIGS. 19 to 22, and FIGS. 25 and 26, the second support member 22 is provided with a first through hole 221 penetrating along the first direction, and the support base 23 is provided with a second through hole 233 corresponding to the first through hole 221. The atomization core assembly 4 penetrates through the first through hole 221 along the first direction and is exposed through the second through hole 233. An exposed part of the atomization core assembly 4 is provided with a conductive structure 442. Accordingly, the conductive structure 442 and the power supply device form an electrical connection when the atomizer 100' is assembled and connected to the power supply device, and power is supplied to the heating element 42 of the atomization core assembly 4. A third sealing piece 241 is arranged in the air guiding cavity 231 near the position of the first through hole 221, and seals the gap between the atomization core assembly 4 and the first through hole 221, thereby preventing the matrix-for-forming-aerosols in the second chamber 212 from flowing into the air guiding cavity 231 through the first through hole 221. The end of the atomization core assembly 4 exposed through the second through hole 233 is in sealing engagement with the second through hole 233. The first liquid absorbing part 234 may be arranged on an inner side surface of the support base 23, and a corresponding sealing ring is arranged at an edge of the second through hole 233. Due to this arrangement, condensed liquid is prevented from leaking out through the second through hole 233.
[0101] By way of specific example, as shown in FIGS. 16, 19, and 25, other areas of the second support member 22 located around the support base 23 are directly exposed by the end of the atomizer housing 1' away from the mouthpiece structure 11'. A drive connection hole 225 corresponding to and interconnecting with the liquid guiding chamber 224 is provided on the second support member 22. When the atomizer 100' is assembled with an external drive mechanism (e.g., a drive mechanism provided in a matched power supply device), an output shaft of the drive mechanism may pass through the drive connection hole 225 and extend into the liquid guiding chamber 224 to form a transmission connection with the adjustment structure 3, thereby driving the adjustment structure 3 to rotate. Specifically, as shown in the examples in FIGS. 24 and 25, a corresponding drive assembly hole 313 may be provided at the end of the adjustment structure 3 facing the drive connection hole 225, and a corresponding flat key or spline structure may be provided in the drive assembly hole 313 to facilitate a detachable transmission connection with the output shaft of the drive mechanism.
[0102] In some embodiments of the present invention, as shown in FIGS. 16 to 18, within the atomizer housing 1', a fourth sealing piece 121 is arranged at the junction between the mouthpiece structure 11' and the airway structure 211, so as to form a sealed connection between the airway structure 211 and the mouthpiece structure 11'. Thus, the matrix-for-forming-aerosols stored in the first chamber 12' is prevented from leaking out through the mouthpiece structure 11'. The inner wall surface of the atomizer housing 1' is provided with a corresponding slot structure 13 at a position corresponding to the mouthpiece structure 11', and the fourth sealing piece 121 is arranged in the slot structure 13 and is fixedly engaged with the slot structure 13. The side of the fourth sealing piece 121 facing the mouthpiece structure 11' is provided with a liquid absorbing groove 1211, and a second liquid absorbing part 122 (e.g., liquid absorbing cotton) is arranged in the liquid absorbing groove 1211 and is configured to absorb condensed liquid or matrix-for-forming-aerosols. Accordingly, the sealing effect at the junction between the airway structure 211 and the mouthpiece structure 11' is further enhanced, and the risk of liquid leakage at the mouthpiece structure 11' is significantly reduced.
[0103] In some embodiments of the present invention, as illustrated in FIGS. 15 and 25, an end of the support assembly 2 away from the mouthpiece structure 11' in the first direction is provided with a plurality of connecting structures 226. Thus, the support assembly 2 may be connected with the power supply device through the plurality of connecting structures 226 when the atomizer 100' is assembled with the power supply device. Preferably, as shown in FIG. 25, the connecting structures 226 may adopt a magnetic attraction structure. Furthermore, magnetic attraction structures having opposite magnetic pole directions may be arranged at corresponding positions on the power supply device, and a detachable connection between the atomizer 100' and the power supply device is formed through magnetic attraction. Accordingly, quick and convenient assembly operation is realized.
[0104] Certainly, in a practical application, the connection structures 226 are not limited to the form of the magnetic attraction structure described above. Other structure, such as snap-fitting structure, may also be adopted. Additionally, the number of connection structures 226 is not limited to two, as shown in FIG. 25. The placement of the connection structures 226 is also not limited to the arrangement at intervals in the third direction shown in FIG. 25. The specific arrangement may be determined as required.
[0105] An atomization device is provided in some embodiments of the present invention. As shown in FIGS. 14, 15, and 27, the atomization device includes the atomizer 100' according to any embodiment in the first aspect and a power supply device 500. The power supply device 500 may be detachably connected to an end of the atomizer 100' away from the mouthpiece structure 11' in the first direction. A drive mechanism 530 and a power supply component 520 are arranged in the power supply device 500. When the power supply device 500 is assembled with the atomizer 100', the drive mechanism 530 may form a transmission connection with the adjustment structure 3 of the atomizer 100'. The power supply component 520 is electrically connected to the drive mechanism 530 to supply power to the drive mechanism 530, thereby driving the adjustment structure 3 to rotate. Accordingly, interconnecting or blocking between the first chamber 12' and the second chamber 212 of the atomizer 100' is realized. The power supply component 520 is further electrically connected to the atomization core assembly 4 of the atomizer 100' to supply power to the atomization core assembly 4. Thus, the heating element 42 of the atomization core assembly 4 is energized and heated, thereby heating the matrix-for-forming-aerosols in the second chamber 212 and generating aerosols. Specifically, the drive mechanism 530 may be a driving motor, and more particularly, a stepper motor.
[0106] Below, a specific example of the atomization device of the present invention will be described with reference to the accompanying drawings.
[0107] As shown in the examples in FIGS. 14 to 27, the atomization device includes an atomizer 100' and a power supply device 500.

The power supply component 520 includes a battery and an electronic control board which are electrically connected. The drive mechanism 530 specifically adopts the stepper motor and is electrically connected to the power supply component 520. The atomizer 100' is arranged to correspond to the power supply device 500 in the first direction, and an end of the power supply housing 510 facing the atomizer 100' is correspondingly provided with a connecting piece and a conductive piece. The conductive piece is electrically connected to a motor of the battery, and the output shaft of the drive mechanism 530 also extends from the end of the power supply housing 510 facing the atomizer 100'.
[0108] As shown in the examples in FIGS. 14 to 18, the atomizer 100' includes an atomizer housing 1', a support assembly 2, an adjustment structure 3, and an atomization core assembly 4. In the first direction, an end of the atomizer housing 1' away from the power supply device 500 is provided with a mouthpiece structure 11', while the end facing the power supply device 500 has an open structure.

The first support member 21 has an airway structure 211 connected to the mouthpiece structure 11'. The second support member 22 is arranged at an end inside the atomizer housing 1' and away from the mouthpiece structure 11' and is in sealing engagement with the inner side wall of the atomizer housing 1'. The side of the second support member 22 facing the mouthpiece structure 11' and the first support member 21 are enclosed to form the second chamber 212, the second chamber 212 corresponds to the mouthpiece structure 11'. The second support member 22 has a liquid guiding groove 223 orientating the opening of the first support member 21. The opening of the liquid guiding groove 223 abuts against the first support member 21 and forms a liquid guiding chamber 224. A side of the second support member 22 away from the first support member 21 is provided with a groove structure extending outside the atomizer housing 1', and the groove structure corresponds to the second chamber 212. The support base 23 is detachably connected to the groove structure of the second support member 22. Accordingly, the support base and the second support member 22 form an air guiding chamber 231. The support base 23 is provided with an air guide hole for external air to flow into the air guiding chamber 231. Specifically, a side of the second support member 22 away from the first support member 21 in the first direction is provided with a plurality of connecting structures 226, and these connecting structures 226 correspond to the connecting pieces on the power supply housing 510 in a one-to-one correspondence manner. Specifically, the connecting structures 226 and the connecting pieces are magnetic pieces having opposite magnetic poles, allowing the atomizer 100' and the power supply device 500 to form a detachable connection through magnetic attraction.
[0109] As shown in FIGS. 16, 17, and 18, in the liquid guiding chamber 224, two first connecting holes 213 are provided in the area corresponding to the liquid guiding groove 223. The two first connecting holes 213 are fan-shaped structures and are symmetrically arranged. A side wall of the liquid guiding groove 223 is provided with two symmetrical second connecting holes 2231. The liquid guiding chamber 224 is a cylindrical cavity, and has a first adjustment position corresponding to the first connecting holes 213 and the second connecting holes 2231. The adjustment structure 3 is arranged inside the liquid guiding chamber 224, and is in sealing engagement with the inner wall surface of the liquid guiding chamber 224. The adjustment structure 3 may rotate inside the liquid guiding chamber 224 so as to adjust the open / closed state of the first connecting holes 213 and the second connecting holes 2231. As shown in FIGS. 18, 19, and 20, the adjustment structure 3 specifically includes a rotating member 31, a blocking piece 32, and a first sealing piece 33. The rotating member 31 is rotatably connected to a groove bottom wall of the liquid guiding groove 223. The rotating member 31 has a rotating shaft 311 extending along the first direction, and an end of the rotating shaft 311 is rotatably connected to the first support member 21. The rotating shaft 311 of the rotating member 31 is connected to the blocking piece 32. The blocking piece 32 specifically includes two symmetrically arranged fan-shaped structures. A liquid guiding channel 321 is formed between the two fan-shaped structures in the circumferential direction. The first sealing piece 33 is made of silicone and is sleeved on an outer surface of the blocking piece 32. The first sealing piece 33 has a sealing engagement with the inner wall of the liquid guiding chamber 224. As shown in FIGS. 19, 20, 21, and 22, an outer surface of the first sealing piece 33 facing the second connecting hole 2231 is provided with a sealing rib 331. The sealing rib 331 has a frame-shaped closed structure that matches the shape of the second connecting hole 2231, and the sealing rib 331 and the liquid guiding channel 321 are spaced apart from each other in the circumferential direction of the rotating member 31. When the blocking piece 32 rotates with the rotating member 31 to align the liquid guiding channel 321 with the first adjustment position, the liquid guiding channel 321 allows the first connecting hole 213 and the second connecting hole 2231 to be interconnected. Accordingly, the first chamber 12' and the second chamber 212 are interconnected. When the blocking piece 32 rotates with the rotating member 31 to align the sealing rib 331 with the first adjustment position of the liquid guiding chamber 224, the sealing rib 331 abuts against a contour edge of the second connecting hole 2231, and the second connecting hole 2231 is completely closed. In this case, the first connecting hole 213 and the second connecting hole 2231 are in a closed state. Accordingly, the first chamber 12' and the second chamber 212 are blocked from each other.
[0110] As shown in FIGS. 21, 22, 23, and 24, the abutting portion between the liquid guiding groove 223 and the first support member 21 is provided with a second sealing piece 242 of silicone structure, which seals the abutting portion. The groove bottom wall of the liquid guiding groove 223 is provided with a first limiting structure 2232, and an end of the rotating member 31 of the adjustment structure 3 facing the groove bottom wall is provided with a second limiting structure 312. Specifically, as shown in the examples in FIGS. 23 and 24, two first limiting structures 2232 are provided and each first limiting structure 2232 has an arc-shaped protrusion structure. The two first limiting structures 2232 are symmetrically arranged in the third direction. Correspondingly, two second limiting structures 312 are provided and each second limiting structure 312 has an arc-shaped groove structure corresponding to the arc-shaped protrusion structure. The two second limiting structures 312 are symmetrically arranged. The extension directions of the arc-shaped protrusion structures and the arc-shaped groove structures are consistent with the rotational trajectory of the rotating member 31, and the rotating member may perform reciprocal rotation in the circumferential direction. The arc-shaped protrusion structure and the arc-shaped groove structure abut at any end in the circumferential direction, thereby forming a rotational limit for the rotating member 31. When the rotating member 31 rotates until the arc-shaped protrusion structure abuts at one end of the arc-shaped groove structure, the first connecting hole 213 and the second connecting hole 2231 are fully opened. When the rotating member 31 rotates until the arc-shaped protrusion structure abuts at the other end of the arc-shaped groove structure, the first connecting hole 213 and the second connecting hole 2231 are fully closed.
[0111] As shown in FIGS. 16, 19, 24, and 25, on the second support member 22, a groove bottom wall of the liquid guiding groove 223 is provided with a drive connection hole 225 penetrating along the first direction. The rotating member 31 of the adjustment structure 3 is provided with a drive assembly hole 313 at the end facing the groove bottom wall. The drive assembly hole 313 is arranged to correspond to the drive connection hole 225, and a flat key structure is provided in the drive assembly hole 313. An output shaft of the drive mechanism 530 in the power supply device 500 passes through the drive connection hole 225 and extends into the drive assembly hole 313 of the rotating member 31. Thus, a transmission connection is formed between the drive mechanism 530 and the rotating member 31 through the flat key structure, and the rotating member 31 is driven to rotate.
[0112] As shown in FIGS. 19 to 22 and FIGS. 25 and 26, the second support member 22 is provided with a first through hole 221 penetrating along the first direction. The first through hole 221 is arranged to be opposite to the mouthpiece structure 11', and the support base 23 is provided with a second through hole 233 corresponding to the first through hole 221. The atomization core assembly 4 passes through the first through hole 221 along the first direction and is exposed through the second through hole 233. The atomization core assembly 4 specifically includes an atomizing core housing 41, a third liquid absorbing part 43, a heating member 42, and an atomizing core base 44. One end of the atomizing core housing 41 is connected to the airway structure 211 of the first support member 21, and the other end of the atomizing core housing 41 extends into the air guiding cavity 231 and is connected to the atomizing core base 44. A third sealing piece 241 having a silicone structure is arranged in the air guiding cavity 231 near the first through hole 221 to seal the gap between the atomizing core housing 41 and the first through hole 221. A plurality of liquid retaining plates 235 are arranged at positions corresponding to the first through hole 221 on the third sealing piece 241. The plurality of liquid retaining plates 235 have the first through hole 221 penetrating into the first chamber and are arranged at intervals along the circumferential direction of the first through hole 221. An end of the atomizing core base 44 away from the atomizing core housing 41 extends into the second through hole 233 and is exposed through the second through hole 233. The side wall of the atomizing core housing 41 located in the second chamber 212 is provided with a plurality of liquid inlet holes 412. The heating member 42 is arranged in the atomizing chamber 411 of the atomizing core housing 41. Specifically, the heating member 42 has a cylindrical heating mesh structure, and a circumferential outer side of the heating member 42 is wrapped with a third liquid absorbing part 43 in the form of liquid absorbing cotton. The third liquid absorbing part 43 may adsorb the matrix-for-forming-aerosols flowing into the atomizing chamber 411 through the liquid inlet holes 412. Accordingly, the matrix-for-forming-aerosols is evenly distributed on the surface of the heating member 42. Each liquid inlet hole 412 is arranged to correspond to a liquid retaining plate 235 to shield and guide the matrix-for-forming-aerosols flowing into the liquid inlet hole 412. The side wall of the atomizing core base 44 is provided with an air guide hole, and a portion of the atomizing core base 44 located in the second through hole 233 is also provided with two conductive holes, and each conductive hole is provided with a conductive structure 442. The two pin structures 421 of the heating member 42 are respectively connected to the two conductive structures 442 to form a positive conductive structure and a negative conductive structure. The two conductive structures 442 are respectively electrically connected to two conductive pieces of the power supply device 500. Thus, the power supply component 520 may supply power to the heating member 42 which heats up in an energized state to heat and atomize the matrix-for-forming-aerosols, thereby generating aerosols. In the air guiding cavity 231, the inner side surface of the support base 23 is provided with a first liquid absorbing part 234 in the form of liquid absorbing cotton. The liquid absorbing part 234 is used to adsorb the condensed liquid in the air guiding cavity 231. Furthermore, a corresponding sealing ring is arranged at an edge of the second through hole 233 to prevent the condensed liquid from leaking out through the second through hole 233.
[0113] As shown in FIGS. 16 to 18, within the atomizer housing 1', a fourth sealing piece 121 having a silicone structure is positioned at the junction between the mouthpiece structure 11' and the airway structure 211, and a sealed connection is formed between the airway structure 211 and the mouthpiece structure 11'. A corresponding slot structure 13 is arranged at an inner top wall of the atomizer housing 1' corresponding to the mouthpiece structure 11'. The fourth sealing piece 121 is positioned within the slot structure 13 and is securely engaged with the slot structure 13. A side of the fourth sealing piece 121 facing the mouthpiece structure 11' is provided with a liquid absorbing groove 1211, a second liquid absorbing part 122 is arranged in the liquid absorbing groove 1211. This second liquid absorbing part 1211 is in the form of liquid absorbing cotton, and is used to adsorb condensed liquid or matrix-for-forming-aerosols.
[0114] In addition, during use, the drive mechanism 530 may be controlled through the electronic control board to control the rotation of the adjustment structure 3. Thus, interconnecting between the first chamber 12' and the second chamber 212 is achieved as needed.
[0115] In some embodiments, a corresponding button or touch control component may also be provided on the atomizer housing 1' or the power supply housing 510. A user may operate the button or the touch control component as needed during use, thereby controlling the interconnected state between the first chamber 12' and the second chamber 212.
[0116] In the atomization device of this embodiment, an atomizer having an independent dual-chamber structure is adopted. The interconnecting or blocking between the two chambers is achieved through the rotational operation of the adjustment structure 3, which may be adjusted according to different usage requirements. Moreover, the circumference of the adjustment structure 3 is in sealing engagement with the liquid guiding chamber 224, and the sealing rib 331 is used to seal the second connecting hole 2231. Accordingly, the risk of liquid leakage may be effectively reduced. Additionally, automatic operation is achieved without the need for manual screwing or other operations, it is convenient to use the atomizer. Furthermore, the power supply device 500 and the atomizer have a detachable structure. The mouthpiece structure 11' of the atomizer and the interior of the air guiding chamber 231 are provided with corresponding sealing pieces and liquid absorbing parts, thereby further reducing the risk of liquid leakage. In addition, the support assembly 2 has a split structure, which is conducive to manufacturing and producing, processing and assembling.
[0117] In addition, the atomization device in this embodiment possesses all beneficial effects of the atomizer 100' in any of the embodiments described above, and therefore will not be repeatedly elaborated here.
[0118] An oil supply device for an atomization device is further provided in some embodiments of the present invention. As shown in FIG. 28, the oil supply device includes: a first oil storage tank 101 and a second oil storage tank 102; a solenoid valve 103 arranged on an oil path between the first oil storage tank 101 and the second oil storage tank 102, and is configured to control a flow of oil from the first oil storage tank 101 to the second oil storage tank 102; a button module 104 configured to output an oil injection instruction according to a user's operation; a power module 105 having an output terminal configured to deliver a supply voltage; a state detection module 106 having a power input terminal 106 for receiving a supply voltage, the state detection module 106 is configured to detect a state of the atomization device; a solenoid valve power supply module 107, where a power input terminal of the solenoid valve power supply module is configured to receive a power voltage, and a power output terminal of the solenoid valve power supply module 107 is connected to a solenoid valve; the solenoid valve power supply module 107 is configured to adjust a power voltage to an operating voltage required to drive the solenoid valve; a control module 108 connected to the output of the power module 105, the output of the button module 104, and a control terminal of the solenoid valve power supply module 107 respectively. The control module 108 is configured to control the solenoid valve power supply module 107 to open or close the solenoid valve according to the oil injection instruction and the state of the atomization device, so as to enable the first oil storage tank 101 to inject oil into the second oil storage tank 102 or stop the operation of injecting oil into the second oil storage tank 102.
[0119] The first oil storage tank 101 is configured for long-term storage of oil or atomized liquid, while the second oil storage tank 102 serves as a temporary oil supply tank which directly provides oil to the atomizing core. The first oil storage tank 101 has a large capacity and may be made of plastic or metal, and has a sealed design. The second oil storage tank 102 is located near the atomizing core, has a smaller volume, and a bottom of the second oil storage tank 102 is provided with an oil inlet that is interconnected with an outlet of the solenoid valve 103. The two tanks are connected via a pipeline, and the solenoid valve is embedded in the pipeline. The solenoid valve 103 serves as an electronic switch component, is configured to determine whether oil flows from the first oil storage tank 101 into the second oil storage tank 102 through control. The solenoid valve 103 may be a normally closed type with a rated operating voltage of 12V, a starting current of about 2A, and a holding current of about 0.3A. The structure of the solenoid valve 103 includes a coil, an armature, a spring, and a valve core. The control signal is provided by the solenoid valve power supply module 107. The button module 104 receives the user operation (e.g., pressing) and sends the oil injection instruction to the control module 108. The button module 104 may be a touch-sensitive button, a capacitive touch component, or a touch-sensitive electrode. The button module 104 is connected to an input of the control module 108, and a signal output is high or low voltage level. The power module 105 provides power for the entire oil supply device. The power module 105 may include a battery pack (e.g., 3.7V lithium battery) or an external power interface (e.g., USB). The state detection module 106 detects a spatial posture or an operating state of the atomization device to determine whether oil injection is allowed. The state detection module 106 may be a three-axis Gsensor (e.g., acceleration / angle sensor), communicates with the control module 108 via I2C or SPI interface to detect a state such as inversion, tilt, and shaking. The solenoid valve power supply module 107 converts a raw voltage provided by the power module 105 into the operating voltage required by the solenoid valve 103. The solenoid valve power supply module 107 may be a Boost type DC-DC Buck-Boost circuit. The control terminal is connected to the control module 108 in order to realize switched on-and-off control. The control module 108 serves as the core control unit, is used to coordinate button instructions and state information to control the operation of the solenoid valve power supply module 107. Generally, the control module 108 is a microcontroller, including multiple GPIO interfaces, I2C communication interface, ADC, level control output port, etc.
[0120] The operating process of the oil supply device in this embodiment is described as follows: 1. Initialization stage: after the atomization device is energized, the control module 108 reads information from the state detection module 106 to determine the current spatial posture of the atomization device (e.g., determining whether the atomization device is inverted, tilted, etc.), and initializes a plurality of functional module. 2. Stage of receiving oil injection command: the user presses the button module 104, the button module outputs a high-level signal to the control module 108 to trigger an oil injection request. 3. State detection stage: when receiving the oil injection command, the control module 108 first reads information from the state detection module 106 to determine whether the device is in a state of allowing oil injection (such as an upright state). If the device is detected to be in an inverted state, the current oil injection request will be ignored to prevent oil from flowing backwards. 4. Solenoid valve activation stage: if oil injection is allowed, the control module 108 outputs a control signal to the solenoid valve power supply module 107 to activate the solenoid valve power supply module 107. The voltage from the power module 105 is converted to a suitable voltage and is supplied to the solenoid valve 103. 5. Oil injection stage: after the solenoid valve 103 is opened, the oil in the first oil storage tank 101 flows into the second oil storage tank 102 through the valve under the action of gravity, automatic oil injection is performed. 6. Ending stage: After the control module 108 sets the oil injection time or receives the user's key input again, the control module 108 closes the solenoid valve power supply module 107, cuts off the power supply to the solenoid valve 103, and stops oil injection. 7. Standby stage: the control module 108 resumes monitoring state, and waits for a next user operation.
[0121] The technical effects of the technical solutions provided in this embodiment are summarized as follows: according to this technical solution, the opening or closing of the solenoid valve may be intelligently controlled based on the user's oil injection instruction and in combination with the current spatial posture of the atomization device, safe and precise oil injection from the first oil storage tank to the second oil storage tank may be achieved. By arranging the solenoid valve and the dedicated power supply module to replace the traditional oil injection method relying on gravity or mechanical valves, the controllability and response speed of the oil injection process are improved. Moreover, combined with the state detection module, oil injection is automatically prohibited when the atomization device is in an abnormal posture such as being inverted, problems such as oil leakage and seepage may be effectively avoided. The security and the intelligence of the atomization device are enhanced.
[0122] As an implementation manner, when the atomization device is in a normal upright state, the first oil storage tank 101 is located above the second oil storage tank 102.
[0123] The first oil storage tank 101 is fixedly mounted in an upper area of the atomization device, and is used for storing a relatively large amount of atomized liquid, such as the atomized liquid with a capacity of 18mL. The second oil storage tank 102 is located below the first oil storage tank 101, is adjacent to the atomization core assembly, with a smaller capacity (e.g., 2mL) and is used for temporary oil supply. The first oil storage tank 101 and the second oil storage tank 102 are connected through an oil passage, and an electromagnetic valve 103 is provided in the oil passage. The electromagnetic valve 103 may be opened or closed under the control of the control module 108. Accordingly, oil is controlled to flow from the first oil storage tank 101 to the second oil storage tank 102. When the atomization device is in a normal upright state, the first oil storage tank 101 is located above the second oil storage tank 102, and the oil may naturally flow to the second oil storage tank 102 under gravity when the electromagnetic valve 103 is opened, and the oil injection operation is achieved. When the atomization device is in an inverted state or a tilted state, the control module 108 may automatically prohibit the electromagnetic valve 103 from being opened according to the position information from the state detection module 106, thus avoiding oil leakage caused by oil flow under abnormal conditions.
[0124] The technical effects of this embodiment are summarized as follows: through the aforesaid structure and the operating mode, not only the automation of the oil injection process is ensured, the safety of the atomization device is also enhanced under an abnormal operating condition.
[0125] As an implementation manner, when the control module 108 detects that the atomization device is in a non-inverted state, the control module 108 controls the solenoid valve power supply module 107 to turn on or turn off the solenoid valve 103 according to the oil injection command. When detecting that the atomization device is in an inverted state, the control module 108 controls the solenoid valve power supply module 107 to turn off the solenoid valve 103.
[0126] The control module 108 intelligently controls turning on and turning off of the solenoid valve power supply module 107 based on user operation and pose information of the atomization device. The state detection module 106 is a three-axis accelerometer sensor used to detect the spatial posture of the atomization device in real time. When the user presses the oil injection button module 104, a button signal is transmitted to the control module 108. The control module 108 first invokes the state detection module 106 to read the current device posture data. If the atomization device is determined as being in a non-inverted state, such as being upright or slightly tilted (e.g., within an angle range of ±60°), the control module 108 sends an activation signal to the solenoid valve power supply module 107. Then, the solenoid valve power supply module 107 is activated and outputs the required operating voltage to the solenoid valve 103, drive the solenoid valve 103 to be open and complete the oil injection process from the first oil storage tank 101 to the second oil storage tank 102. If the atomization device is determined as being in an inverted state (e.g., the atomization device is flipped over more than 120°), the control module 108 will prevent the solenoid valve power supply module 107 from being energized to ensure that the solenoid valve 103 remains closed. Even if the user sends out an oil injection command, the oil injection operation will not be executed. Thus, oil is effectively prevented from being mistakenly injected and flowing out when it is in an inverted state, and the risk of oil leakage is avoided.
[0127] The technical effects of this embodiment are summarized as follows: when the control module 108 detects that the atomization device is in a non-inverted state, the control module controls the solenoid valve power supply module 107 to turn on or turn off the solenoid valve 103 only when an oil injection command is received. Thus, a safe oil injection in a normal posture of the atomization device is achieved. When the atomization device is in an inverted state, even if the user performs a maloperation, the control module 108 will forcibly control the solenoid valve power supply module 107 to turn off the solenoid valve 103, thereby prohibiting the oil injection operation. Accordingly, problems such as oil backflow and leakage caused due to upside-down placement of the atomization device are effectively avoided. The safety and the intelligence of the atomization device in various usage postures are improved.
[0128] As an implementation manner, the solenoid valve power supply module 107 steps up the supply voltage and outputs the operating voltage to the solenoid valve.
[0129] When the supply voltage of the atomization device (such as 3.7V~4.2V output by a lithium battery) is insufficient to directly drive the solenoid valve 103, the solenoid valve power supply module 107 steps up the voltage, and converts the voltage into an operating voltage (such as 12V) being capable of driving the solenoid valve 103, and outputs the stabilized voltage after boosting to the solenoid valve 103. Thus, the solenoid valve 103 is enabled to be open normally or maintain operating state. Reliable operation of the solenoid valve 103 is ensured, energy efficiency and control accuracy are improved.
[0130] As an implementation manner, as shown in FIG. 29, the solenoid valve power supply module 107 includes a power management chip 204, a switch module 201, a first filter module 202, a boost module 203, a second filter module 206, and a feedback module 205. One end of the switch module 201 serves as the power input terminal of the solenoid valve power supply module 107, while the other end of the switch module 201 is connected to one end of the first filter module 202, the first terminal of the boost module 203, and the first signal sampling terminal of the power management chip 204. A control terminal of the switch module 201 serves as a control terminal of the solenoid valve power supply module 107. The other end of the first filter module 202 is grounded. A second terminal of the boost module 203 is connected to a second signal sampling terminal of the power management chip 204. A third terminal of the boost module 203 is connected to the first terminal of the feedback module 205 and one end of the second filter module 206, and is constituted as an output terminal of the solenoid valve power supply module 107. The other end of the second filter module 206 is grounded. A third signal sampling terminal of the power management chip 204 is connected to a second terminal of the feedback module 205, and a third terminal of the feedback module 205 is grounded.
[0131] The power management chip 204 serves as the core device of the entire boost control, collects key potential information and load information, adjusts a boost switching frequency and a duty cycle, and achieves closed-loop stable control of the output voltage. The power management chip 204 may be a commonly used Boost control IC, integrating functions such as voltage reference source, error amplifier, PWM modulator, and overvoltage protection. The switch module 201 switches power-on or power-off of the power supply under the control of the control module 108, thereby determining whether the boost module 203 starts working through control. The switch module 201 may be one or more N-channel metal oxide semiconductor field-effect transistors (MOSFETs) or P-channel MOSFETs. the gate electrode of the switch module 201 is controlled by the output signal of the control module 108, the drain electrode is connected to an input power supply and the source electrode is connected to the filter module 206 and the boost module 203. The first filter module 202 filters the input voltage, reduces power ripple interference, and improves boost stability. The first filter module 202 may be a parallel filtering network composed of one or a plurality of electrolytic capacitors or ceramic capacitors. The boost module 203 boosts the low-voltage power supply to the high voltage (e.g., 12V) required for operating the solenoid valve. The boost module 203 may include an inductor, a current control MOSFET, a freewheeling diode, etc. The second filter module 206 filters an output voltage of the boost module 203, suppresses high-frequency ripple and noise, and ensures stable power supply to the solenoid valve. The second filter module 206 may be one or a plurality of large-capacity capacitors. The feedback module 205 divides the output voltage proportionally and feeds the divided voltage to the power management chip 204, thereby participating in closed-loop regulation and control. Thus, it is ensured that the output is stabilized at the target voltage. The feedback module 205 may be a voltage divider composed of two resistors with high-precision.
[0132] The overall operating process of this embodiment is as follows: 1. Initial state: the solenoid valve power supply module 107 is not open, the switch module 201 is in the switched off state, and the boost module 203 has no voltage input. 2. Control signal triggering state: when the control module 108 detects the user's oil injection command and the atomization device is in a non-inverted state, the control module 108 sends a high-level signal to the switch module 201 to turn on the switch module 201. The supply voltage is input to the solenoid valve power supply module 107. 3. Boost startup state: after the switch module 201 is switched on, the input voltage is filtered by the first filter module 202 and then input to the boost module 203, which starts to operate. The power management chip 204 simultaneously collects an input voltage, an inductor current (or a pin voltage of the inductor), and output voltage feedback signal through a first signal sampling terminal, a second signal sampling terminal, and a third signal sampling terminal respectively, thereby forming a closed-loop regulation control. 4. Output boosted voltage state: the boost module 203 boosts the input voltage to a target operating voltage (e.g., 12V), which is then filtered by the second filter module 206 and is output to the solenoid valve 103 to turn on the solenoid valve 103. 5. Feedback and steady state: the output voltage is returned to the power management chip 204 through a feedback module 205 (e.g., a resistive voltage divider) for dynamically adjusting the PWM duty cycle to maintain a constant output voltage. 6. Turned off state: after the oil injection is completed, the control module 108 controls the switch module 201 to be turned off, the solenoid valve power supply module 107 is powered off, and the solenoid valve 103 is turned off.
[0133] The technical effects of this embodiment are summarized as follows: the solenoid valve power supply module 107 may efficiently boost the input supply voltage upon receiving a control signal and output a stable operating voltage to drive the solenoid valve 103 to operate. By virtue of a closed-loop control implemented by the power management chip 204 and in combination with the feedback module 205 and filter module, precise voltage regulation and dynamic stability may be achieved. It is ensured that the solenoid valve 103 responds quickly and operates reliably during the oil injection process.
[0134] By way of example, as shown in FIG. 30, the switch module 201 includes a MOSFET Q1, a transistor Q2, a fifth resistor R5, a seventh resistor R7, a ninth resistor R9, and a tenth resistor R10. A source electrode of the MOSFET Q1 and one end of the fifth resistor R5 are commonly connected as one end of the switch module 201. The other end of the fifth resistor R5 is connected to one end of the seventh resistor R7 and a collector electrode of the transistor Q1, respectively. The other end of the seventh resistor R7 is connected to a gate electrode of the MOSFET Q1. A drain electrode of the MOSFET Q1 is the other end of the switch module 201. A base electrode of the transistor Q1 is connected to one end of the ninth resistor R9 and one end of the tenth resistor R10, respectively. The other end of the ninth resistor R9 is the control terminal of the switch module 201. An emitting electrode of the transistor Q2 and the other end of the tenth resistor R10 are grounded.
[0135] The fifth resistor R5 is used to limit the current flowing from the power input terminal to the control circuit. The seventh resistor R7 serves as a pull-up resistor which pulls up a gate voltage of the MOSFET Q1 when the control signal is invalid, thereby ensuring reliable turning-off of the MOSFET Q1. The ninth resistor R9 is a current-limiting resistor which is used to limit the current entering the base electrode of the transistor Q2 from the control signal. The tenth resistor R10 is a pull-down resistor which is used to prevent the transistor Q2 from being falsely turned on due to floating. The working process is as follows: when the control module 108 outputs a high-level control signal to the ninth resistor R9, the current drives the transistor Q2 to be turned on, Accordingly, the potential at the collector electrode drops rapidly, such that the gate voltage of the MOSFET Q1 is lower than the source voltage. Thus, the MOSFET Q1 is turned on and supply voltage is output to a post-stage circuit for power up. When the control module 108 cancels the control signal or outputs a low-level signal, the transistor Q2 is turned off, and the collector voltage of the transistor Q2 is pulled up to approximate the source voltage of the MOSFET Q1 by the seventh resistor R7. Thus, the voltage between the gate electrode and the source electrode of the MOSFET Q1 is zero, the PMOS Q1 is turned off and the power output is cut off. Thus, power supplying is stopped.
[0136] The technical effect in this embodiment are summarized as follows: by virtue of the structure and the control logic of the switch module 201, the control of power supplying of the solenoid valve 103 is achieved. Not only the response speed and the stability of operation is ensured, but also power loss in the standby state is effectively reduced. Accordingly, the energy efficiency and the reliability of the overall system are enhanced.
[0137] By way of example, as shown in FIG. 30, the boost module 203 includes an inductor L1 and a first diode D1. One end of the inductor L1 is a first terminal of the boost module 203, and the other end of the inductor L1 and an anode of the first diode D1 are commonly connected as a second terminal of the boost module 203. A cathode of the first diode D1 is a third terminal of the boost module 203.
[0138] The boost module 203 is used to boost an input voltage from the switch module 201 to a target voltage capable of driving the solenoid valve 103 to operate. The boost module 203 includes an inductor L1 and a first diode D1. During operation, when the control module 108 drives the switch module 201 to be turned on, the input voltage is applied across the inductor L1, and the inductor L1 stores magnetic energy. Subsequently, the switch module 201 is turned off, at this moment, a current path is interrupted, the inductor L1 maintains current flow due to the inability of the current to change abruptly, an induced voltage across the terminals of the inductor L1 is formed. At this time, the voltage across the inductor L1 increases to a value higher than the input voltage, thereby causing the first diode D1 to be turned on. The energy released by the inductor L1 is transmitted to the output terminal to achieve a boosted voltage output. The first diode D1 has the function of unidirectional conduction, energy freewheeling, and avoidance of backflow of output voltage during this process, thereby ensuring continuous and stable operation of boosting voltage.
[0139] The technical effects in this embodiment are summarized as follows: the boost module 203 may achieve a voltage increase from a low-voltage battery voltage (e.g., 3.7V) to a target voltage (e.g., 12V), thereby providing sufficient driving voltage for the solenoid valve 103. Moreover, the device has the advantages of simple circuit structure, fast response, and high efficiency.
[0140] By way of example, as shown in FIG. 30, the feedback module 205 includes an eighth resistor R8 and an eleventh resistor R11. One end of the eighth resistor R8 serves as a first terminal of the feedback module 205, and the other end of the eighth resistor R8 and one end of the eleventh resistor R11 are commonly connected to form a second terminal of the feedback module 205. The other end of the eleventh resistor R11 serves as a third terminal of the feedback module 205.
[0141] The feedback module 205 is used to proportionally divide the output voltage of the boost module 203 and feed it back to the power management chip 204, thereby achieving closed-loop stable control of the output voltage. The feedback module 205 includes an eighth resistor R8 and an eleventh resistor R11. During operation, the high voltage (e.g., 12V) output by the boost module 203 is divided in series by the eighth resistor R8 and the eleventh resistor R11, thereby forming a stable intermediate voltage (e.g., 1.2V) at a connection point of the two resistors R8 and R11. This voltage is input as a feedback signal to a feedback sampling terminal of the power management chip 204. The power management chip 204 automatically adjusts a duty cycle of a PWM control signal based on the comparison between this feedback voltage and an internal reference voltage thereof, thereby achieving closed-loop regulation and voltage stabilization control of the output voltage of the boost module 203.
[0142] The technical effect in this embodiment lies in the ability to achieve real-time monitoring, automatic adjustment, and high-precision stable output of the output voltage by the circuit. It is ensured that the solenoid valve 103 always receives appropriate driving voltage under different operating conditions. Accordingly, the reliability and the intelligence of the power supply system are effectively improved.
[0143] By way of example, the first filter module 202 includes a fourth capacitor C4, a fifth capacitor C5, and a sixth capacitor C6. One end of the fourth capacitor C4, one end of the fifth capacitor C5, and one end of the sixth capacitor C6 are commonly connected as a first terminal of the first filter module 202, while the other end of the fourth capacitor C4, the other end of the fifth capacitor C5, and the other end of the sixth capacitor C6 are commonly connected as a second terminal of the first filter module 202.
[0144] The first filter module 202 is utilized to filter the input voltage outputted by the switch module 201, in order to enhance the stability of the input voltage and suppress high-frequency noise and voltage ripple.
[0145] By way of example, the second filter module 206 includes a seventh capacitor C7, an eighth capacitor C8, and a ninth capacitor C9. One end of the seventh capacitor C7, one end of the eighth capacitor C8, and one end of the ninth capacitor C9 are commonly connected as a first terminal of the second filter module 206. The other end of the seventh capacitor C7, the other end of the eighth capacitor C8, and the other end of the ninth capacitor C9 are commonly connected as a second terminal of the second filter module 206.
[0146] The second filter module 206 is used to filter the output voltage of the boost module 203, in order to reduce the ripple and the noise of the solenoid valve power supply, and enhance the stability and the electromagnetic compatibility of the output voltage.
[0147] In some embodiments, the second filter module 206 further includes a second diode D2 and a twelfth capacitor C12. A cathode of the second diode D2 and one end of the twelfth capacitor C12 are commonly connected and then connected to one end of the ninth capacitor C9, while an anode of the second diode D2 and the other end of the twelfth capacitor C12 are grounded.
[0148] The working process of this circuit structure is as follows: when the control module 108 sends out an oil injection command and detects that the atomization device is in a non-inverted state, a control terminal outputs a high-level signal to the switch module 201, thereby enabling the ninth resistor R9 to transmit the signal to the base electrode of the transistor Q2. Accordingly, the transistor Q2 is switched on. At this time, the MOSFET Q1 is switched on, and the supply voltage is allowed to enter the power supply path. The supply voltage first passes through the first filter module 202 consisting of the fourth capacitor C4, the fifth capacitor C5, and the sixth capacitor C6, where composite filtering is performed on the input supply voltage. Then, the supply voltage is output to the input terminal of the inductor L1. In the boost module 203, the inductor L1 begins to store energy. When the power management chip 204 controls the switch to be turned off periodically, the inductor L1 releases energy, and the current flows through the first diode D2 which becomes conductive, and a boosted voltage is output. This output voltage is further filtered by the second filter module 206 consisting of the seventh capacitor C7, the eighth capacitor C8 and the ninth capacitor C9, and is stably output to the solenoid valve 103, Thus, the solenoid valve is driven to be open. Simultaneously, the feedback module 205, which is consisted of the eighth resistor R8 and the eleventh resistor R11, performs voltage division and sampling on the output voltage, and transmits the feedback voltage to the feedback sampling terminal of the power management chip 204, thereby forming a closed-loop control. Accordingly, the PWM duty cycle is dynamically adjusted and the output voltage is stabilized. After the oil injection is completed, the control module 108 cancels the command, outputs a low level signal to switch off the transistor Q2. Accordingly, the MOSFET Q1 is switched off, the power supply is cut off, the solenoid valve 103 is closed, and the oil injection process is terminated.
[0149] An atomization device is further provided in some embodiments of the present invention. The atomization device includes the oil supply device provided above.
[0150] An oil supply control circuit for the atomization device is further provided in some embodiments of the present invention. As shown in FIG. 31, the oil supply control circuit includes: a switch module 101; a voltage stabilization module 102 which receives a supply voltage B+ and is used to stabilize the supply voltage B+ and output a first voltage; a position sensing module 103, where a power input terminal of the position sensing module 103 receives a first voltage V0, and the position sensing module 103 is configured to detect the spatial pose information of the atomization device; a motor drive module 104, where a power input terminal of the motor drive module 104 receives the first voltage V0, and a signal output terminal of the motor drive module 104 is connected to a motor, the motor drive module 104 is used to drive the motor to rotate in a forward direction or a reverse direction, thereby opening or closing the oil injection valve of the oil storage tank; a control module 105, where a power input terminal of the control module 105 receives the first voltage V0, a first signal input of the control module 105 is connected to a signal output of the switch module 101, a second signal input of the control module 105 is connected to a signal output of the position sensing module 103, and a signal output of the control module 105 is connected to a control terminal of the motor drive module 104.
[0151] The control module 105 is configured to control the motor drive module 104 to rotate the motor 106 in a predetermined direction when receiving switch information from the switch module 101 and detecting that the atomization device is in a preset position through the position sensing module 103, in order to achieve oil injection or stopping oil injection.
[0152] The switch module 101 is configured to receive an oil supply command signal input by a user, which serves as a triggering condition for starting or stopping the oil injection process. The switch module 101 includes, but is not limited to, the following structures: button switch, capacitive touch switch, Hall switch, or near field communication (NFC) wake-up module. When the user wishes to inject oil into the storage tank or stop the oil injection, the switch module 101 is triggered, and outputs a corresponding high / low voltage level signal to the control module 105. The voltage regulation module 102 is configured to receive the supply voltage B+ from the main power supply, stabilize the supply voltage B+, and output the first voltage V0 to be used by subsequent functional modules. The voltage regulation module 102 includes, but is not limited to, the following structures: LDO linear regulator, DC-DC buck converter, etc. The voltage regulation module 102 provides a stable operating voltage (e.g., 3V) to drive the control module 105, the position sensor, and the motor drive module 104. Thus, reliable operation of the system is ensured. The position sensing module 103 is configured to monitor a spatial posture of the atomization device in real time and output a status signal reflecting the posture to the control module 105. The position sensing module 103 includes, but is not limited to, the following structures: a three-axis accelerometer, a six-axis IMU module (accelerometer + gyroscope), etc. The position sensing module 103 is configured to determine whether the atomization device is in a spatial posture (e.g., placed horizontally, facing up, etc.) allowing for oil injection to prevent oil leakage caused by incorrect oil injection when the atomization device is tilted or in an inverted placement. The motor drive module 104 is configured to drive the connected motor 106 to rotate in a forward direction or reverse direction according to the control signal from the control module 105, thereby controlling the opening and closing of the oil injection valve in the storage tank. The motor drive module 104 includes, but is not limited to, the following structures: H-bridge motor drive chip or MOSFET array. The motor drive module 104 drives a micro motor to operate according to a PWM control signal or a direction control signal to open or close the oil injection valve. Forward rotation indicates opening the oil injection channel, while reverse rotation indicates closing the oil injection channel. The control module 105 is used for logical judgment and outputting control signals, and is the core control unit of the system. The control module 105 may be a microcontroller unit (MCU). The supply terminal of the control module 105 receives the first voltage V0 as the operating power supply. The first signal input receives the oil supply trigger signal from the switch module 101. The second signal input receives the posture signal from the position sensing module 103. When the switch module 101 sends out an oil supply command and the device's posture meets the preset condition (e.g., upward placement), the switch module 101 outputs a control signal to the motor drive module 104. The motor 106 is controlled to rotate in a forward direction or reverse direction, thereby achieving oil injection or termination of oil injection.
[0153] The working process of this embodiment includes: the user triggers the switch module 101, such as pressing the oil injection button. The switch module 101 sends a signal to the control module 105. The control module 105 reads the pose information output by the current position sensing module 103. If it is determined that the current device is in a preset oil injection posture (e.g., the device stands upright or in horizontal placement), the control module 105 outputs a control signal to the motor drive module 104. The motor drive module 104 drives the motor to rotate according to the control signal, opens the oil injection valve, and realizes oil supply. If an oil injection termination condition is detected (e.g., the oil injection time reaches a preset value, the user releases the switch, etc.), the control module 105 instructs the motor to rotate in the reverse direction to close the oil injection valve. The system enters a standby or sleep state, and waits for a next oil injection instruction.
[0154] The technical effects of the technical solution provided in this embodiment are summarized as follows: by arranging the switch module 101, the voltage stabilization module 102, the position sensing module 103, the motor drive module 104, and the control module 105, intelligent control of the oil injection process for the atomization device is achieved. Compared with the existing methods relying on manual or gravity-based oil injection, according to this solution, whether oil injection is allowed is determined based on the spatial posture of the atomization device after user's operation, opening and closing of the oil injection valve is precisely controlled through motor drive. Thus, the problem of oil infiltrating into heating components caused by excessive oil storage pressure is effectively avoided. The security and the reliability of oil supply are significantly improved, the service life of the atomization device is prolonged, and user experience is improved.
[0155] As an implementation manner, the third signal input of the control module 105 is connected to the signal output of the motor drive module 104, and is used to collect a current signal, and controls the process of driving the motor 106 by the motor drive module 104 based on the current signal.
[0156] The control module 105 may further include a third signal input, this third signal input is used to receive a feedback signal from the motor drive module 104, the feedback signal may be a current sampling signal. For example, a current sampling resistor is arranged in the motor drive module 104, the current sampling resistor is connected in series in the motor circuit to convert the operating current passing through the motor into a voltage signal. This voltage signal is conditioned and output as a feedback signal to the control module 105. The control module 105 collects the current feedback signal through the third signal input thereof and compares the current feedback signal with the preset threshold value to determine the current operating state of the motor. When detecting that the motor current gradually increases and exceeds a preset threshold, the motor is determined as being in a locked state, which indicates that the oil injection valve has reached a mechanical limit position or oiling is complete. In this case, the control module 105 sends out a stop control signal to the motor drive module 104 to stop motor operation. When the motor is in a normal operating state (the current is within the normal range), the control module 105 allows continuous oiling. After the oiling is complete, the control module 105 may control the motor to rotate in a reverse direction again to close the oil injection valve. Whether the oil injection valve has been fully closed is determined again through the current signal.
[0157] The technical effects of this embodiment are summarized as follows: by introducing a current acquisition function into the control module 105, real-time monitoring and intelligent determination of the motor's operating state are achieved. By recognizing whether the motor is in a locked-rotor state, the opening and closing of the oil injection valve may be precisely controlled, excessive oil injection or mechanical damage is avoided. The reliability and the accuracy of oil injection control are effectively improved, and the system's intelligence level and the operational safety are enhanced.
[0158] As an implementation manner, as shown in FIG. 32, the switch module 101 is a button switch SW. One end of the button switch SW serves as the signal output of the switch module 101, and the other end of the button switch SW is grounded.
[0159] The key switch SW is used to receive user operation instructions and serves as the start trigger for the entire fuel supply control circuit. When the user presses the key switch SW, it closes, causing the signal SW1_WK output from its signal output terminal to transition from high level to low level. This level change serves as the trigger signal for the control module 105.
[0160] The technical effect of this embodiment lies in that the key switch has a simple structure, responses quickly, and is prone to be integrated, and therefore is suitable for control operations in portable atomization devices.
[0161] As an implementation manner, the voltage regulator module 102 is a low-voltage linear voltage regulator. A power input of the low-voltage linear voltage regulator receives the supply voltage, and a power output of the low-voltage linear voltage regulator outputs a first voltage.
[0162] The low-voltage linear voltage regulator is used to stabilize the external power supply (e.g., 3.7V voltage output from a lithium battery) into a stable low voltage (e.g., 3.0V) required by the system. This low voltage is used by the position sensing module 103, the control module 105, and motor drive module 104. The function of the low-voltage linear voltage regulator lies in converting unstable or high input voltage into a constant output voltage to ensure stable operation of a post-stage circuit. The output voltage has small ripple, electromagnetic interference to sensitive devices such as MCUs and sensors may be effectively reduced. The standard of the power supply is unified, the overall stability and the consistency of the circuit are improved.
[0163] By way of example, as shown in FIG. 33, the low-voltage linear voltage regulator includes a chip U1, a resistor R12, a capacitor C5, and a capacitor C6. The pin VIN of chip U1 is connected to one end of resistor R12 and one end of the capacitor C5, respectively. The other end of resistor R12 is connected to the supply voltage B+. The pin GND of the chip U1, the other end of the capacitor C5, and the other end of the capacitor C6 are grounded. The pin VOUT of the chip U1 and one end of the capacitor C6 are commonly connected and output a voltage of 3.0V.
[0164] The technical effects of this embodiment are summarized as follows: by arranging a low-voltage linear voltage regulator, the input supply voltage is stabilized to the first voltage required by the system. Thus, it is ensured that the position sensing module 103, the control module 105, and the motor drive module 104 operate reliably under low-noise and stable voltage conditions, thereby improving the stability, electromagnetic compatibility, and service life of the entire fuel supply control system.
[0165] As an implementation manner, the position sensing module 103 is a digital three-axis position sensor, and the signal output of the digital three-axis position sensor is connected in communication with a second signal input of the control module 105 via I2C bus.
[0166] The digital three-axis position sensor is used to detect the real-time pose information of the atomization device in three-dimensional space, the pose information includes the states of the atomization device, including tilt, inverted placement, horizontal placement. This sensor integrates a three-axis acceleration detection function, and may output acceleration data in the X, Y, and Z directions. The sensor communicates with the control module 105 via the I 2< C bus to transmit pose information to the control module 105 for analysis and determination. The digital three-axis position sensor determines whether the atomization device is currently in a normal operation posture by detecting the acceleration values of each axis. When detecting that the atomization device is not in a preset posture (such as inverted placement), the digital three-axis position sensor sends status information to the control module 105 to prohibit the system from performing oil injection operation, thereby enhancing the security during use. The sensor communicates with the control module 105 stably through the I 2< C interface, supports low-power operation, and is suitable for portable device applications.
[0167] By way of example, as shown in FIG. 34, a SCX pin of the digital three-axis position sensor U3 is connected to one end of a resistor R13, the other end of the resistor R13 is respectively connected to one end of a resistor R16, one end of a capacitor C8, and a VDD pin of the digital three-axis position sensor U3, and receives a voltage of 3.0V. The other end of capacitor C8 is grounded. A NC pin of digital three-axis position sensor U3 and one end of resistor R14 are commonly connected and receive a voltage of 3.0V. A CS pin of digital three-axis position sensor U3 is connected to the other end of resistor R14.
[0168] The technical effects of this embodiment are summarized as follows: by arranging a digital three-axis position sensor, real-time monitoring of the spatial posture of the atomization device is achieved. The control module 105 may determine whether the atomization device is in a preset operating state based on the pose information fed back by the sensor. The oil injection operation is only allowed when the conditions are met, accidental triggering of oil injection is effectively avoided in case that the atomization device is in an inverted placement state or normal state. The security and the intelligence level of the oil supply control system are improved.
[0169] As an implementation manner, as shown in FIG. 35, the motor drive module 104 includes a single-channel H-bridge drive chip 202, a sampling module 201, a first filter module 203, and a second filter module 204. One end of the sampling module 201 serves as the power input of the motor drive module 104, the other end of the sampling module 201 is connected to one end of the first filter module 203 and the power input of the single-channel H-bridge drive chip respectively, and is constituted as the signal output of the motor drive module 104. The other end of the first filter module 203 is grounded, and one end of the second filter module 204 is connected to the first output of the single-channel H-bridge drive chip 202, while the other end of the second filter module 204 is connected to the second output of the single-channel H-bridge drive chip 202. The first control terminal and the second control terminal of the single-channel H-bridge drive chip 202 are constituted as the control terminals of the motor drive module 104.
[0170] The single-channel H-bridge drive chip 202 provides the motor with forward and reverse rotation drive capabilities. The single-channel H-bridge drive chip 202 has a first control terminal and a second control terminal which receive PWM control signals or level signals from the control module 105, respectively. The polarity of the output terminal is controlled through different logical combinations. Accordingly, the motor is driven to rotate in a forward direction or a reverse direction. The chip operates within a voltage range of 2V to 6V, with a continuous output current capability of up to 1.1A, and has an over-temperature protection function. The sampling module 201 is used to monitor an operating current of the motor 106. One end of the sampling module serves as the power inputs of the entire motor drive module 104, is connected to a first voltage output by the voltage regulation module 102. The other end of the sampling module is respectively connected to power inputs of the first filter module 203 and the single-channel H-bridge drive chip 202, thereby constituting a signal output of the motor drive module 104 used for feeding back current change signals to the control module 105 for collection and analysis. Generally, the sampling module 201 is composed of low-resistance current sampling resistors. The first filter module 203 filters and reduces noise in the voltage signal output by the sampling module 201 to avoid high-frequency interference caused by instantaneous start or stop of the motor, which could affect the accuracy of current sampling. For example, an electrolytic capacitor or a ceramic chip capacitor may be used, one end of this capacitor is connected to the sampling module 201 and the other end of this capacitor is grounded. The second filter module 204 is connected between two outputs of the single-channel H-bridge drive chip 202, and serves to buffer and filter bidirectional PWM signals of the drive motor, suppresses voltage spikes caused by the motor's back electromotive force, and protect the circuit from unstable operation, which may be implemented using a differential RC filter or a low ESR capacitor symmetric structure.
[0171] By way of example, as shown in FIG. 36, the sampling module 201 is represented by a sampling resistor R18. One end of the sampling resistor R18 is connected to one end of the sampling module 201, and the other end of the sampling resistor R18 is connected to the other end of the sampling module 201. The first filter module 203 is a first capacitor C11. One end of the first capacitor C11 is connected to one end of the first filter module 203, and the other end of the first capacitor C11 is connected to the other end of the first filter module 203. The second filter module 204 is a second capacitor C10. One end of the second capacitor C10 is connected to one end of the second filter module 204, and the other end of the second capacitor C10 is connected to the other end of the second filter module 204. One end of the resistor R17 is connected to the other end of the sampling resistor R18, one end of the first capacitor C11, and the VCC pin of the single-channel H-bridge drive chip U2, respectively. The other end of the resistor R17 is connected to the control module 105. This circuit utilizes a low-voltage single-channel H-bridge drive chip GC9111 which may provide a continuous output current of 1.1A and operates with a voltage range of 2V to 6V, is provided with PWM input / output interfaces IN1 and IN2, and has an over-temperature protection function. Specifically, the resistor R18 serves as a current sampling resistor for detecting motor current, and ADC serves as a motor current sampling signal, is connected to a ADC port of the microcontroller.
[0172] The technical effects of this embodiment are summarized as follows: stable driving and real-time current sampling function of the motor 106 are achieved by providing components including the single-channel H-bridge drive chip 202, the sampling module 201, the first filter module 203, and the second filter module 204. The single-channel H-bridge drive chip 202 provides reliable forward and reverse rotation control. The sampling module 201 realizes monitoring of the current state, and effectively suppresses electromagnetic interference with reference to the filter module. Thus, the accuracy and the security of motor control are improved. The oil injection process is more intelligent and stable, abnormal valve operation or locked-rotor runaway are avoided.
[0173] As an implementation method, the control module 105 sends control signals to the first control terminal and the second control terminal of the single-channel H-bridge drive chip 202, respectively. When the current is detected to reach a preset value during the forward or reverse rotation of the motor 106, the motor 106 is controlled to stop rotating through the single-channel H-bridge drive chip 202.
[0174] The two control signal outputs of the control module 105 are respectively connected to the first control terminal and the second control terminal of the single-channel H-bridge drive chip 202, are used to control the rotation direction of the motor 106. Based on user's key press operations and posture determination result, the control module 105 outputs control signals of different combinations to the first control terminal and the second control terminal. Accordingly, the motor 106 is enabled to perform forward or reverse rotation actions, thereby achieving oil injection or closing of the oil injection valve. During the rotation of the motor 106, the control module 105 receives a current feedback signal from the sampling module 201 through the third signal input thereof and continuously monitors current change. When the control module 105 detects that the motor current value reaches a preset threshold (e.g., the motor is in locked-rotor condition due to mechanical limitation by the valve), the control module 105 determines that the current action has been completed. At this time, the control module 105 immediately controls the single-channel H-bridge drive chip 202 to close the output channel by, for example, setting the first control terminal and the second control terminal to low level or high level. Accordingly, the motor is enabled to stop rotation, thus, energy wase, component damage, or abnormal noise which are caused due to continuous driving are avoided.
[0175] By way of example, as shown in FIG. 37, the power input terminal VCC of the control module U4 receives a first voltage. A first signal input PB5 of the control module U4 is connected to a signal output of the switch module 101, a second signal input PF0 of the control module U4 is connected to a signal output of the position sensing module 103, and a third signal input terminal PA2 of the control module U4 is connected to a signal output of the motor drive module 104. The signal output PA0 and the signal output PA5 of the control module U4 are respectively connected to the first control terminal and the second control terminal of the motor drive module.
[0176] The technical effects of this embodiment are summarized as follows: the current detection is utilized to replace complex position detection mechanisms. Accordingly, intelligent determination and security control of the motor's operating state are realized, and the automation level, the response speed, and the reliability of the oil injection system are improved.
[0177] With reference to FIG. 32, FIG. 33, FIG. 34, FIG. 36, and FIG. 37, the circuit implementation principle in this embodiment is as follows: the button switch SW is pressed and an electromagnetic valve control command is sent to the MCU accordingly. After receiving the button information, the MCU first reads the position information detected by the digital three-axis position sensor U3 through I2C. After determining that the atomization device is not in an inverted placement, the MCU controls the single-channel H-bridge drive chip U2 through the PWM control signal to start the motor (begin oil injection). At the same time, the MCU samples and calculates the motor current through ADC. When the motor current is too high (the motor is in a locked-rotor state and the paddle is at the boundary position), the control is disconnected, and the oil injection time is timed. When the oil injection time reaches 2 minutes, a reverse rotation is initiated, and the oil injection valve is closed. When the oil injection valve is closed, the ADC is detected to calculate the motor current. When the motor current is too high (the motor is in a locked-rotor state, and the oil injection valve is fully closed), the control is disconnected at this time. In this way, oil injection from the upper oil storage tank to the lower oil storage tank is achieved. The button switch SW may be pressed at any time to close and open the oil injection valve, the ADC is used to detect the signal, the motor current is monitored in real time when the oil injection valve is open.
[0178] An atomization device is provided in some embodiments of the present invention. The atomization device includes an oil supply control circuit, a motor, and an oil storage tank provided above. The motor is connected to the oil injection valve in the oil storage tank. The oil storage tank includes an upper oil storage tank and a lower oil storage tank. When the motor opens the oil injection valve, the upper oil storage tank injects oil into the lower oil storage tank.
[0179] The motor is used to drive the oil injection valve to open or close. After receiving the control signal from the oil supply control circuit, the motor is rotated to drive the connecting mechanism to enable physical opening and closing of the oil injection valve, thereby controlling whether the oil in the upper oil storage tank is injected into the lower oil storage tank. The oil storage tank stores oil and supplies the oil required by the atomization part in stages. The upper oil storage tank serves as the main liquid storage container used for storing a relatively large amount of oil. The lower oil storage tank serves as a temporary liquid storage tank used for short-term oil supply. When the motor drives the oil injection valve to open, the oil in the upper oil storage tank flows into the lower oil storage tank to ensure a stable oil supply for the atomizer's operation. The oil injection valve controls the flow of oil between the upper oil storage tank and the lower oil storage tank. The oil injection valve is open or closed under the drive of the motor, oil is allowed to flow from the upper oil storage tank into the lower oil storage tank as needed, oil supply is ensured. The oil supply control circuit controls start and stop of the motor to achieve the control of opening or closing of the oil injection valve. A control signal is output to the motor drive module based on user operations or internal logic determination of the device to enable the motor to perform oil injection or stop oil injection.
