Technical field

[0001] The present invention relates to the technical field of atomizers, and in particular to an atomizing assembly and an atomizing device. [Background Technology]

[0002] Before existing atomizer devices reach the user, the atomizer core is typically filled with atomizing matrix. Since the atomizer core is exposed to the outside air, fluctuations in ambient air pressure or temperature during transportation can cause changes in the atomizer core's saturated atomizing matrix adsorption rate, creating a risk of atomizing matrix leakage. Some atomizer devices also require a method of injecting atomizing matrix into the atomizer core upon first use. While this can prevent atomizing matrix leakage during transportation, the atomizer core can still leak if left unused for even a short period of time.

[0033] The present application provides an atomizer assembly. Referring to Figures 1 to 4, the atomizer assembly 100 may include an outer cavity 10, an inner sleeve 20 and an atomizer core 30. A suction nozzle 21 is provided at one end of the inner sleeve 20, and the end of the inner sleeve 20 away from the suction nozzle 21 is accommodated in the outer cavity 10. The atomizer assembly 100 is provided with a main oil tank 11, a subsidiary oil tank 12 and an atomizer tank 13. The main oil tank 11 and the subsidiary oil tank 12 are used to store the atomizer matrix. Generally speaking, the main oil tank 11 has a larger capacity than the subsidiary oil tank 12. Under normal circumstances, the atomizer matrix is ​​stored in the main oil tank 11. The main oil tank 11 is formed between the inner sleeve 20 and the outer cavity 10, and the atomizer tank 13 and the subsidiary oil tank 12 are located in the inner sleeve 20. The atomizer tank 13 is connected to the subsidiary oil tank 12 and the suction nozzle 21 respectively, and the atomizer core 30 is installed in the atomizer tank 13. The atomizing chamber 13 is connected to the auxiliary oil chamber 12, allowing the auxiliary oil chamber 12 to supply atomized substrate to the atomizing core 30 installed in the atomizing chamber 13. The atomized substrate is heated and atomized by the atomizing core 30 to generate an aerosol, which then reaches the nozzle 21 connected to the atomizing chamber 13. The inner sleeve 20 can move relative to the outer cavity 10 under the action of an external force to change the cross-sectional area of ​​the fluid channel between the main oil chamber 11 and the auxiliary oil chamber 12, thereby sealing the atomized substrate within the main oil chamber 11 or allowing the atomized substrate to flow to the auxiliary oil chamber 12.

[0034] The atomizer assembly 100 provided in the present application is provided with a main oil tank 11, a subsidiary oil tank 12 and an atomizing tank 13. The main oil tank 11 is formed between the inner sleeve 20 and the outer cavity 10, and the atomizing tank 13 and the subsidiary oil tank 12 are located in the inner sleeve 20. The inner sleeve 20 can move relative to the outer cavity 10 under the action of an external force to change the cross-sectional area of ​​the fluid channel between the main oil tank 11 and the subsidiary oil tank 12. Through the above-mentioned arrangement, the atomizing matrix is ​​normally stored in the main oil tank 11, and the subsidiary oil tank 12 supplies the atomizing matrix to the atomizing core 30. According to the consumption of the atomizing matrix in the subsidiary oil tank 12, the user can adjust the atomizing matrix in the main oil tank 11 to enter the subsidiary oil tank 12 for temporary storage, realize on-demand supply, avoid the long-term storage of a large amount of atomizing matrix in the subsidiary oil tank 12, thereby preventing the leakage of the atomizing matrix. Specifically, during transportation or when the product is stationary for a long time, the cross-sectional area of ​​the fluid channel between the main oil tank 11 and the auxiliary oil tank 12 can be reduced until the atomized matrix is ​​sealed in the main oil tank 11, thereby preventing the atomized matrix from leaking during transportation or use of the product.

[0035] In one embodiment, as shown in Figures 3 to 5, the outer cavity 10 includes an atomizing base 14, which is provided at one end of the outer cavity 10 away from the suction nozzle 21, and the inner sleeve 20 is movably sleeved on the atomizing base 14, and the auxiliary oil tank 12 and the atomizing tank 13 are formed on the inner side of the atomizing base 14. The inner sleeve 20 is movably sleeved on the atomizing base 14, so that the inner sleeve 20 can move relative to the outer cavity 10 under the action of an external force to change the cross-sectional area of ​​the fluid channel between the main oil tank 11 and the auxiliary oil tank 12. A plurality of sealing silicones can be provided at the abutment between the inner sleeve 20 and the atomizing base 14 to enhance the airtightness of the main oil tank 11 and the auxiliary oil tank 12, and prevent the atomized matrix from leaking through the gap at the abutment between the inner sleeve 20 and the atomizing base 14.

[0036] 3 and 4 , in order to adjust the cross-sectional area of ​​the fluid passage between the main oil tank 11 and the auxiliary oil tank 12 , in one embodiment, a first oil inlet hole 1411 is provided on the atomizing base 14 , and a corresponding second oil inlet hole 221 is provided on the inner sleeve 20 . When the inner sleeve 20 moves relative to the outer cavity 10 , the opposing area between the first oil inlet hole 1411 and the second oil inlet hole 221 can be changed. Specifically, under normal conditions, the first oil inlet hole 1411 and the second oil inlet hole 221 are offset, so that the main oil tank 11 and the auxiliary oil tank 12 are not connected, thereby sealing the atomized matrix within the main oil tank 11 to prevent the atomizer core 30 from directly communicating with the atomized matrix in the main oil tank 11 and leaking. When the atomized matrix in the auxiliary oil tank 12 is consumed less, the inner sleeve 20 and the outer cavity 10 can be moved relative to each other, thereby fluidly connecting the first oil inlet hole 1411 and the second oil inlet hole 221, and the atomized matrix in the main oil tank 11 flows into the auxiliary oil tank 12. The number of the first oil inlet hole 1411 and the second oil inlet hole 221 can be one or more, and is not specifically limited here.

[0037] The movement of the inner sleeve 20 relative to the outer cavity 10 can be rotational or translational. In one embodiment, the first oil inlet hole 1411 and the second oil inlet hole 221 are offset in the horizontal direction. Under the action of external torque, the inner sleeve 20 rotates relative to the outer cavity 10, so that the first oil inlet hole 1411 and the second oil inlet hole 221 are fluidically connected. In one embodiment, the first oil inlet hole 1411 and the second oil inlet hole 221 are offset in the vertical direction. The inner sleeve 20 is movably arranged relative to the outer cavity 10 along the length direction of the atomizer assembly 100 so that when pressed, the main oil tank 11 and the auxiliary oil tank 12 are fluidically connected. When applying torque, it is necessary to hold the opposite ends of the atomizer assembly 100 and rotate it. When the outer surface of the atomizer assembly 100 is relatively smooth, it is easy to slip when rotating the inner sleeve 20. Therefore, applying pressing force is more convenient than applying torque, and the atomizer assembly 100 has a certain playability, which can enhance the user experience.

[0038] In one embodiment, as shown in Figures 3, 4, and 6, the atomizer assembly 100 includes an atomizer sleeve 40, an atomizer bin 13 is formed in the atomizer sleeve 40, and the atomizer sleeve 40 is docked with the atomizer base 14 to form a secondary oil tank 12 located between the atomizer sleeve 40 and the atomizer base 14. By providing the atomizer sleeve 40, the atomizer sleeve 40 and the atomizer base 14 are docked to form the secondary oil tank 12, which is located between the main oil tank 11 and the atomizer bin 13. The secondary oil tank 12 can be connected to both the main oil tank 11 and the atomizer bin 13, so that the main oil tank 11 is not directly connected to the atomizer bin 13, thereby avoiding leakage of the atomized matrix.

[0039] In one embodiment, as shown in Figures 4 and 6, an annular flange 41 is formed on the outer peripheral surface of the atomizing sleeve 40, and the first portion 42 of the atomizing sleeve 40 is accommodated in the atomizing base 14. The annular flange 41, the first portion 42, and the atomizing base 14 together form the auxiliary oil tank 12. The annular flange 41 abuts against the atomizing base 14 to seal the auxiliary oil tank 12 and prevent the atomized matrix in the auxiliary oil tank 12 from leaking. The first portion 42 is provided with a third oil inlet hole 421 that connects the auxiliary oil tank 12 and the atomizing bin 13, so that the atomized matrix in the auxiliary oil tank 12 can enter the atomizing bin 13 through the third oil inlet hole 421, thereby supplying the atomized matrix to the atomizing core 30.

[0040] In one embodiment, as shown in Figure 7, the atomizer base 14 includes a base side wall 141, a base bottom plate 142 and an atomizer tube 143. The base bottom plate 142 is connected to the side of the base side wall 141 away from the suction nozzle 21, the atomizer tube 143 is connected to the base bottom plate 142, and the atomizer bin 13 is formed on the inner side of the atomizer tube 143. The atomizer sleeve 40 is sleeved on the atomizer tube 143, and the base side wall 141, the base bottom plate 142 and the atomizer sleeve 40 are surrounded to form a secondary oil tank 12. The first oil inlet hole 1411 is provided on the base side wall 141. The inner sleeve 20 is movably sleeved on the base side wall 141. When the suction nozzle 21 is pressed, the inner sleeve 20 slides along the base side wall 141, and the sealing silicone can be provided between the inner sleeve 20 and the base side wall 141. The atomizer core 30 can be pre-assembled into the atomizer tube 143. For flexible atomizer cores, such as cotton cores, the atomizer tube 143 can prevent the atomizer core 30 from being deformed during assembly, thereby ensuring the taste of the aerosol generated by atomization of the atomizer assembly 100. Outer cotton can also be provided between the atomizer tube 143 and the atomizer sleeve 40 to extend the service life of the atomizer core 30. The atomizer tube 143 is provided with a hollow hole connected to the third oil inlet hole 421 so that the atomized matrix can be adsorbed to the atomizer core 30. By providing the atomizer tube 143, the atomizer sleeve 40 is sleeved on the atomizer tube 143, which can facilitate the installation and positioning of the atomizer sleeve 40 and prevent the atomizer sleeve 40 from shifting after installation.

[0041] Please continue to refer to Figures 2 to 4. In one embodiment, the atomizer assembly 100 includes a reset member 50, which elastically acts on the inner sleeve 20 and the outer cavity 10 respectively, so as to drive the inner sleeve 20 to reset after the external force is removed, thereby blocking the communication between the main oil tank 11 and the auxiliary oil tank 12. Specifically, the reset member 50 can be connected to the inner sleeve 20 and the atomizer sleeve 40 respectively, and the atomizer sleeve 40 is docked with the atomizer base 14 of the cavity 10, so as to transmit the elastic action of the reset member 50 to the outer cavity 10. The reset member 50 can also be connected to the inner sleeve 20 and the atomizer base 14 respectively, such as being connected to the base side wall 141, to transmit the elastic action of the reset member 50 to the outer cavity 10. When the inner sleeve 20 is in rotational motion relative to the outer cavity 10, the reset member 50 can be a torsion spring; when the inner sleeve 20 is in translational motion relative to the outer cavity 10, the reset member 50 can be a spring. When the consumption of the atomized matrix in the auxiliary oil tank 12 is reduced, an external force can be applied to make the inner sleeve 20 and the outer cavity 10 move relative to each other, and the fluid between the first oil inlet hole 1411 and the second oil inlet hole 221 is connected. At the same time, the inner sleeve 20 drives the reset member 50 to move and produce elastic deformation; when the external force is removed, the reset member 50 elastically deforms and recovers, driving the inner sleeve 20 to reset, so that the first oil inlet hole 1411 and the second oil inlet hole 221 are staggered under normal conditions, thereby blocking the communication between the main oil tank 11 and the auxiliary oil tank 12, and sealing the atomized matrix in the main oil tank 11.

[0042] Referring to Figure 5 , the outer chamber 10 may further include an oil tank top cover 15, a first side wall 16, and an oil tank bottom cover 17. The oil tank top cover 15 and the oil tank bottom cover 17 are respectively mounted on opposite ends of the first side wall 16. The oil tank top cover 15, the oil tank bottom cover 17, the first side wall 16, and the inner sleeve 20 enclose the main oil tank 11.

[0043] The oil tank cover 15 is disposed at one end near the suction nozzle 21, with the suction nozzle 21 at least partially extending outside the oil tank cover 15. A sealing silicone sealant may be provided at the interface between the suction nozzle 21 and the oil tank cover 15 to enhance the airtightness of the main oil tank 11 and prevent leakage of the atomized matrix through the gap between the suction nozzle 21 and the oil tank cover 15.

[0044] It is understandable that the outer cavity 10 can be open at both ends or at one end, as long as the inner sleeve 20 can be inserted into the outer cavity 10 through the opening. Specifically, the atomizing base 14, the oil tank top cover 15, the first side wall 16, and the oil tank bottom cover 17 can be separately processed and then assembled; the atomizing base 14, the first side wall 16, and the oil tank bottom cover 17 can be integrally formed, with the opening provided at the end where the oil tank top cover 15 is located; or the oil tank top cover 15 and the first side wall 16 can be integrally formed, with the end where the oil tank bottom cover 17 is located open, and the oil tank bottom cover 17 is assembled into the first side wall 16.

[0045] 8 , the oil tank bottom cover 17 has an air inlet 171. When the atomizer base 14 is assembled to the oil tank bottom cover 17, the atomizer tube 143 is partially inserted into the air inlet 171. The atomizer tube 143 and the air inlet 171 have an interference fit, which can enhance the airtightness of the air inlet passage.

[0046] In one embodiment, the inner sleeve 20 moves in translation relative to the outer chamber 10, and a first groove 172 is provided on the oil tank bottom cover 17, as shown in Figures 4 and 8. The provision of the first groove 172, on the one hand, limits the maximum stroke of pressing the inner sleeve 20, preventing the suction nozzle 21 from separating from the oil tank top cover 15; on the other hand, it raises the bottom elevation of the main oil tank 11, allowing the first oil inlet hole 1411 and the second oil inlet hole 221 to be positioned as close to the bottom surface of the main oil tank 11 as possible, thereby preventing the atomized substrate at the bottom of the main oil tank 11 from being wasted due to inability to be atomized.

[0047] In one embodiment, the outer cavity 10 and the inner sleeve 20 are respectively provided with a first locking portion and a second locking portion, which can be selectively engaged to lock the relative position of the inner sleeve 20 and the outer cavity 10. When the relative position of the inner sleeve 20 and the outer cavity 10 is locked, the inner sleeve 20 cannot move relative to the outer cavity 10, the fluid passage between the main oil tank 11 and the auxiliary oil tank 12 is blocked, and the atomized matrix in the main oil tank 11 cannot flow to the auxiliary oil tank 12. The temporary storage amount of atomized matrix in the auxiliary oil tank 12 is relatively small. When the atomized matrix in the auxiliary oil tank 12 is consumed, it cannot be replenished and the auxiliary oil tank 12 cannot supply atomized matrix to the atomizer core 30. The atomizer assembly 100 cannot function normally, thereby preventing minors from misusing the atomizer assembly 100.

[0048] Specifically, the first locking portion can be an annular groove (not shown) provided on the base side wall 141 of the atomizing base 14, and the annular groove extends along the circumferential direction of the base side wall 141. Accordingly, the second locking portion can be a limiting protrusion (not shown) provided at the contact point between the inner sleeve 20 and the base side wall 141. When it is necessary to lock the relative position of the inner sleeve 20 and the outer cavity 10, the inner sleeve 20 and the outer cavity 10 can be rotated relative to each other by a preset angle so that the limiting protrusion is accommodated in the annular groove. The groove wall of the annular groove can limit the limiting protrusion from moving along the length direction of the atomizing assembly 100. The user cannot make the main oil tank 11 and the auxiliary oil tank 12 fluid communicate by pressing the inner sleeve 20, and the atomizing assembly 100 cannot work normally. When it is necessary to unlock the relative position of the inner sleeve 20 and the outer cavity 10, the inner sleeve 20 and the outer cavity 10 can be rotated relative to each other by a preset angle in the opposite direction so that the limiting protrusion is disengaged from the annular groove, thereby releasing the locked state.

[0049] Referring to Figures 9 and 10 , in one embodiment, a top cover flange 151 is provided on the side of the oil tank top cover 15 away from the free end of the suction nozzle 21. The top cover flange 151 surrounds the outer circumference of the suction nozzle 21. The first locking portion is a circumferentially extending retaining groove 152 defined on the inner wall of the top cover flange 151. One end of the retaining groove 152 is provided with an unlocking opening 153. The second locking portion is a protrusion 211 provided on the outer wall of the suction nozzle 21. The protrusion 211 can enter the retaining groove 152 along the unlocking opening 153. The retaining groove 152 and the protrusion 211 cooperate to lock the inner sleeve 20 in the outer cavity 10. Specifically, after the protrusion 211 enters the limiting groove 152 along the unlocking opening 153, the inner sleeve 20 can rotate relative to the oil tank top cover 15 in the first direction (counterclockwise as shown in Figure 9) by a preset angle until it can no longer rotate. The movement of the protrusion 211 is restricted by the limiting groove 152, and the inner sleeve 20 can no longer continue to move relative to the outer cavity 10 in the first direction. At this time, the main oil tank 11 and the auxiliary oil tank 12 are in a blocked state, and the auxiliary oil tank 12 cannot supply atomization matrix to the atomization core 30, thereby preventing minors from misusing the atomization assembly 100. During use, the inner sleeve 20 is rotated in the opposite direction by a preset angle along the second direction (clockwise as shown in Figure 9) relative to the oil tank top cover 15, so that the protrusion 211 is aligned with the unlocking port 153, and the protrusion 211 can slide out of the limiting groove 152 along the unlocking port 153, thereby unlocking the inner sleeve 20 from the outer cavity 10. The inner sleeve 20 can move relative to the outer cavity 10 so that the main oil tank 11 and the auxiliary oil tank 12 are connected, and the atomizer assembly 100 is used normally.

[0050] It is understandable that the relative rotation between the inner sleeve 20 and the oil tank top cover 15 can be the rotation of the oil tank top cover 15 or the rotation of the inner sleeve 20. In one embodiment, the relative rotation between the inner sleeve 20 and the oil tank top cover 15 is the rotation of the oil tank top cover 15. In the initial state, the protrusion 211 is located outside the limit groove 152. The user presses the suction nozzle 21 to push the inner sleeve 20 toward the oil tank bottom cover 17. The atomized matrix can enter the auxiliary oil tank 12 from the main oil tank 11 to replenish the atomized matrix for the auxiliary oil tank 12; when the user is finished using the oil tank, the user can rotate the oil tank top cover 15 to lock the suction nozzle 21 to the oil tank top cover 15 so that it cannot be pushed.

[0051] Specifically, the oil tank top cover 15 is provided with a buckle 154, as shown in FIG9 , and a corresponding circumferentially extending slot 161 is provided on the first side wall 16 , as shown in FIG3 . When the oil tank top cover 15 is assembled onto the first side wall 16 , the buckle 154 is accommodated in the slot 161 . When the oil tank top cover 15 is rotated, the buckle 154 can slide along the slot 161, allowing the inner sleeve 20 and the oil tank top cover 15 to rotate relative to each other. The extension length of the slot 161 corresponds to the preset rotation angle, so that the outer cavity 10 can lock or unlock the inner sleeve 20 when the oil tank top cover 15 is rotated. Relatively speaking, rotating the oil tank top cover 15 is more convenient to hold. In addition, the larger radius of the oil tank top cover 15 makes rotation more labor-saving.

[0052] Please continue to refer to Figure 10. The inner sleeve 20 may also include a second side wall 22 and an airway tube 23. The airway tube 23 is connected to the suction nozzle 21. One end of the atomizing sleeve 40 is inserted into the airway tube 23. The second side wall 22 is arranged around the outer periphery of the airway tube 23. The second side wall 22 is connected to the suction nozzle 21. The second oil inlet hole 221 is arranged on the second side wall 22. An installation space is formed between the second side wall 22 and the airway tube 23 for installing the reset member 50, which can prevent the reset member 50 from affecting the main oil tank 11 and the air intake channel. Accordingly, a groove can be provided on the annular flange 41 of the atomizing sleeve 40 for fixing the reset member 50. When the suction nozzle 21 is pressed, the airway tube 23 slides along the atomizing sleeve 40. Sealing silicone can be provided between the airway tube 23 and the atomizing sleeve 40 to enhance the airtightness of the air intake channel. The length of the airway tube 23 matches the pressing stroke of the inner sleeve 20, so that when the inner sleeve 20 is pressed, the airway tube 23 always keeps in contact with the atomizing sleeve 40 without separating from the atomizing sleeve 40, thereby ensuring the airtightness of the air inlet channel.

[0053] The atomizer core 30 includes an oil guide 31, a heater 32, and a heater pin 33, as shown in Figure 3. The oil guide 31 is used to adsorb the atomized matrix to the heater 32, and the heater 32 heats the atomized matrix to generate an aerosol. The atomizer core 30 is connected to the power supply via the heater pin 33. The oil guide 31 is wrapped around the outer periphery of the heater 32, and the heater pin 33 is connected to the heater 32. The oil guide 31 is a porous medium. The oil guide 31 can be a porous fiber material such as fiber cotton, non-woven fabric, linen, chemical fiber fabric, etc. The oil guide 31 can also be a porous ceramic material. The above materials all have good lipophilicity and oil retention. The material of the heater 32 can be one of stainless steel, nickel-chromium-aluminum alloy, nickel-chromium alloy, iron-chromium-aluminum or titanium alloy. The heater 32 can have a mesh structure to increase the contact area between the heater 32 and the oil guide 31 and improve the heating efficiency. The heater 32 can also be a spiral heating wire, which is not specifically limited here.

[0054] The present application provides an atomizing device. Referring to Figure 11, the atomizing device 300 may include the atomizing assembly 100, the control assembly 310, and the power supply assembly 320 as described above. The control assembly 310 can control the atomizing assembly 100 to be connected or disconnected with the power supply assembly 320 according to the suction action, so as to control the atomizing assembly 100 to heat the atomizing matrix to generate aerosol or stop heating. Specifically, when inhaling through the mouthpiece 21, the control assembly 310 senses the negative pressure in the atomizing device 300, and the control assembly 310 controls the atomizing assembly 100 to be connected with the power supply assembly 320, and the atomizing core 30 to heat the atomizing matrix to generate aerosol; when the inhalation stops, the control assembly 310 controls the atomizing assembly 100 to be disconnected from the power supply assembly 320, and the atomizing core 30 stops heating the atomizing matrix.

[0055] The atomizer assembly provided in this application has at least the following beneficial effects:

[0056] 1. The atomizing assembly 100 is provided with a main oil tank 11, a subsidiary oil tank 12, and an atomizing tank 13. The main oil tank 11 is formed between the inner sleeve 20 and the outer cavity 10. The atomizing tank 13 and the subsidiary oil tank 12 are located in the inner sleeve 20. The inner sleeve 20 can move relative to the outer cavity 10 under the action of an external force to change the cross-sectional area of ​​the fluid channel between the main oil tank 11 and the subsidiary oil tank 12. Through the above arrangement, the atomizing matrix is ​​normally stored in the main oil tank 11, and the subsidiary oil tank 12 supplies the atomizing matrix to the atomizing core 30. According to the consumption of the atomizing matrix in the subsidiary oil tank 12, the user can adjust the atomizing matrix in the main oil tank 11 to enter the subsidiary oil tank 12 for temporary storage, so as to realize on-demand supply and avoid the long-term storage of a large amount of atomizing matrix in the subsidiary oil tank 12, thereby preventing the leakage of the atomizing matrix.

[0057] 2. The inner sleeve 20 is movably arranged relative to the outer cavity 10 along the length direction of the atomizer assembly 100. Applying pressing force is more convenient than applying torque, and the atomizer assembly 100 has a certain playability, which can enhance the user experience.

[0058] 3. By setting the atomizing sleeve 40, the atomizing sleeve 40 is connected to the atomizing base 14 to form a secondary oil tank 12. The secondary oil tank 12 is located between the main oil tank 11 and the atomizing tank 13, so that the main oil tank 11 is not directly connected to the atomizing tank 13, which can avoid leakage of the atomized matrix.

[0059] 4. The atomizing assembly 100 includes a reset member 50 , which can drive the inner sleeve 20 to reset, and seal the atomized matrix in the main oil tank 11 under normal conditions to prevent the atomized matrix from leaking.

[0060] 5. The oil tank top cover 15 cooperates with the suction nozzle 21 to lock the inner sleeve 20 in the outer cavity 10, thereby preventing minors from misusing the atomizer assembly 100.
