[0027] In order to have a clearer understanding of the technical features, purposes and effects of this application, the specific implementation methods of this application are now described in detail with reference to the accompanying drawings.

[0028] As shown in Figures 1 to 4, an electronic atomization device according to an embodiment of the present application includes a main unit and an atomizer 20 installed in the main unit. The main unit further includes a housing 100, an atomization chamber 10, a rotating base 30, a nozzle 200, a battery cell 300, and a control assembly 400.

[0029] The housing 100 has a first end and a second end connected in its length direction. The atomizer 10 is accommodated in the first end of the housing 100, and the atomizer 20 is accommodated in the atomizer 10; the nozzle 200 is arranged at the first end of the housing 100 and is detachably covered on the atomizer 10. The rotating base 30 is arranged in the housing 100 and is fitted on the end of the atomizer 10 away from the nozzle 200. The rotating base 30 and the atomizer 10 can rotate relative to each other. The battery cell 300 and the control component 400 are accommodated in the second end of the housing 100. The battery cell 300 is electrically connected to the control component 400, and the atomizer 20 is powered by the control component 400.

[0030] Among them, as shown in Figure 4, at least two sub-atomization bins 11 can be provided in the atomization bin 10 through partitions and the like, and each sub-atomization bin 11 extends along the length direction of the atomization bin 10; at least two sub-atomization bins 11 are distributed along the circumference of the atomization bin 10 and can be isolated from each other. There are at least two atomizers 20, which are consistent with the number of sub-atomization bins 11, and one atomizer 20 is vertically arranged in one sub-atomization bin 10. In this embodiment, as shown in Figure 5, four sub-atomization bins 11 are provided in the atomization bin 10, and four atomizers 20 are respectively accommodated in the four sub-atomization bins 11, and the angle between two adjacent atomizers 20 is 90°.

[0031] The atomizing chamber 10 has a first end and a second end that are opposite to each other. The atomizing chamber 10 faces the housing 100 with its first end and is accommodated in the housing 100. The second end of the atomizing chamber 10 corresponds to the outside of the first end of the housing 100, and the suction nozzle 200 covers the second end of the atomizing chamber 10. The rotating base 30 is fitted on the first end of the atomizing chamber 10 (hereinafter referred to as the first end). The surface of the rotating base 30 facing the atomizing chamber 10 defines a connection area, which is provided with a power supply electrode 40 and an air inlet 31. The power supply electrode 40 is electrically connected to the control component 400. The rotating base 30 and the atomization bin 10 can rotate relative to each other, so that the connection area on the rotating base 30 can correspond to the bottom of any sub-atomization bin 11 in the atomization bin 10, and the power supply electrode 40 on the connection area and the lead of the atomizer 20 in the sub-atomization bin 11 are conductively connected by abutment and other means, and the air inlet 31 can be connected to the atomization channel of the sub-atomization bin 11 and the atomizer 20 directly above the connection area. This makes it simple and convenient to replace the atomizer 20 in the electronic atomization device through a rotating operation.

[0032] The relative rotation between the rotating base 30 and the atomization chamber 10 can drive the rotating base 30 and the atomization chamber 10 to move away from or approach each other along the direction of the rotation axis during the relative rotation, thereby making the sub-atomization chamber and the power supply electrode have a paired state and a separated state. In the paired state, the power supply electrode 40 is conductively connected to the atomizer 20 in the sub-atomization chamber 11; in the separated state, the power supply electrode 40 and the atomizer 20 in the sub-atomization chamber 11 are away from each other and not connected. Specifically, as shown in Figures 1 and 2, the rotating base 30 is fitted in the first end of the atomization chamber 10, so that the rotating base 30 is fitted with its outer circumferential surface and the inner circumferential surface of the first end of the atomization chamber 10.

[0033] In order to achieve relative rotation between the rotating base 30 and the atomizing chamber 10 and drive the power supply electrode 40 to move toward or away from the sub-atomizing chamber 11, thereby electrically connecting or disconnecting with the corresponding atomizer 20, a guide structure is provided between the atomizing chamber 11 and the rotating base 30. The guide structure can convert circular rotation (rotation) into axial movement, guiding the atomizing chamber 10 and the rotating base 30 to move away from or toward each other along the direction of the rotation axis during relative rotation. Therefore, when the atomizing chamber 11 and the rotating base 30 rotate relative to each other, the guide structure drives the rotating base 30 to move back and forth in the axial direction of the atomizing chamber 11, thereby causing the power supply electrode 40 to move toward or away from the sub-atomizing chamber 11.

[0034] The guiding structure may further be a matching concave-convex structure, such as a combination of a convex block and a groove.

[0035] In conjunction with Figures 1, 6, and 7, in an optional embodiment, the guide structure includes a guide profile disposed on the outer periphery of the rotating base 30; the guide profile is provided with a slot 33, and the slot 33 has a depth in a direction away from the first end of the atomization chamber 10. Alternatively, the guide profile may include an annular step 32 disposed on the outer periphery of the rotating base 30, the annular step 32 being provided with at least two slots 33, and the first end of the atomization chamber 10 being provided with at least one protrusion 12 adapted to the slot 33. The protrusion 12 can fit within the slot 33, or can move along or abut against the step surface of the annular step 32.

[0036] When the atomizing bin 10 and the rotating base 30 rotate relative to each other, the protrusion 12 is driven to be embedded in the card slot 33 or to leave the card slot 33 and abut against the annular step 32, driving the rotating base 30 to move back and forth in the axial direction of the atomizing bin 10 relative to the atomizing bin 10, so that the power supply electrode 40 is conductively connected to an atomizer 20, and the air inlet 31 is connected to the atomizing channel of the atomizer 20. Among them, the embedding of the protrusion 12 in the card slot 33 corresponds to the matching state, and the disengagement of the protrusion 12 from the card slot 33 corresponds to the separation state. The cooperation between the atomizing bin 10 and the rotating base 30 is carried out through the annular step 32, the card slot 33 and the protrusion 12, so that the circumferential rotation of the rotating base 30 relative to the atomizing bin 10 is converted into axial movement, thereby driving the connection area on the rotating base 30 to cooperate with or disengage the atomizer 20.

[0037] Among them, when the atomizing chamber 10 is rotated so that the protrusion 12 is embedded in the card slot 33 from the annular step 32, the rotating base 30 moves toward the atomizing chamber 10, and at the same time drives the power supply electrode 40 on the rotating base 30 to approach the atomizer 20 currently facing, and is conductively connected to the lead of the atomizer 20. When the atomizing chamber 10 is rotated so that the protrusion 12 leaves the card slot 33 and reaches the annular step 32, the rotating base 30 moves toward the direction away from the atomizing chamber 10, and at the same time drives the power supply electrode 40 on the rotating base 30 to detach from the atomizer 20 originally conductively connected; when the atomizing chamber 10 is continued to rotate so that the protrusion 12 is embedded in another adjacent card slot 33, the rotating base 30 moves toward the atomizing chamber 10 again, and at the same time drives the power supply electrode 40 on the rotating base 30 to approach the atomizer 20 facing after rotation, and is conductively connected to the lead of the atomizer 20, thereby achieving the purpose of replacing the atomizer 20.

[0038] It can be understood that the bottom surface of the slot 33 and the step surface of the annular step 32 are connected by an arc-shaped transition surface to ensure that the protrusion 12 can move smoothly from the step surface into the slot 33, or move smoothly from the slot 33 to the step surface.

[0039] The number of slots 33 on the annular step 32 matches the number of atomizers 20, and the distribution of the slots 33 on the annular step 32 corresponds to the circumferential distribution of the atomizers 20 around the atomizer chamber 10. When the protrusion 12 engages with the slot 33, the rotating base 20 is rotated into position. The connection area on the rotating base 30 now faces directly below an atomizer 20, thereby achieving conductive connection between the power supply electrode 40 and the atomizer 20, and connecting the air inlet 31 to the atomization channel of the atomizer 20.

[0040] The protrusion 12 can be a cylindrical shape, or a spherical or hemispherical shape with a smooth surface. Preferably, two protrusions 12 are provided, one on each side of the first end of the atomization chamber 10. The two protrusions 12 are simultaneously embedded in the two slots 33 or simultaneously abut against the annular step 32. The relative arrangement of the two protrusions 12 can improve the mating stability and rotational balance of the rotating base 30 and the atomization chamber 10.

[0041] The atomizer 20 can be implemented using an atomizer of the prior art (such as a cigarette cartridge, etc.), for example, the structure includes an air duct, an atomizing assembly arranged in the air duct, etc., and the lead of the atomizing assembly extends out of the air duct to connect to the power supply electrode 40.

[0042] In the connection area of ​​the rotating base 30, electrode holes are provided corresponding to the power supply electrodes 40. The power supply electrode 40 includes two electrode members, one corresponding to the positive and negative poles, respectively. Therefore, there are two corresponding electrode holes, each accommodating two electrode members. Each electrode member of the power supply electrode 40 is inserted into the corresponding electrode hole, with one end extending from the surface of the rotating base 30 facing the atomizer 20 for conductive connection with the lead of the atomizer 20; the other end of the electrode member extends from the surface of the rotating base 30 facing away from the atomizer 20 for conductive connection with the control assembly 400. The air inlet 31 can be located between the two electrode members in the connection area.

[0043] In one embodiment, after the power supply electrode 40 is electrically connected to the atomizer 20 facing it, the other atomizers 20 in the atomizer chamber 10 are in an inactive state. At the same time, the two ends of the sub-atomizer chamber 11 outside the connection area in the atomizer chamber 10 can be sealed by the suction nozzle 200 and the rotating base 30 respectively. The atomizers 20 in the inactive state in the sub-atomizer chamber 11 are not ventilated, which also avoids the problem of flavor degradation due to ventilation. To improve the sealing of the sub-atomizer chamber 11, an airway seal 34 can be provided on the rotating base 30 to seal the atomization channels of the inactive atomizers 20 and the corresponding sub-atomizer chamber 11, which can also prevent ventilation from diverting the airflow of the active atomizers 20.

[0044] The airway seal 34 is mainly arranged on the surface of the rotating base 30 facing the atomization chamber 10 and covers other areas on the surface except the connection area. The airway seal 34 can be made of elastic and sealing materials such as silicone.

[0045] Furthermore, a liquid-absorbing sponge 35 may be provided on the surface of the rotating base 30 facing the atomizer chamber 10. The liquid-absorbing sponge 35 covers the area outside the connection area, preferably surrounding the periphery of the connection area. The liquid-absorbing sponge 35 is provided to absorb liquid leaking from the atomizer 20, preventing the liquid from seeping into the second end of the housing 100 and affecting the operation of the battery cell 300 and the control assembly 400.

[0046] In the embodiments shown in Figures 3 and 6, an airway seal 34 and a liquid absorbent cotton 35 are provided on the surface of the rotating base 30 facing the atomization chamber 10. The airway seal 34 mainly covers the position directly opposite the atomizer outside the connection area, and the liquid absorbent cotton 35 can be connected to the airway seal 34 and surround the outer periphery of the connection area.

[0047] The atomizer bin 10 is rotatable relative to the housing 100. This allows the atomizer 20 to be replaced while the housing 100 remains stationary. The second end of the atomizer bin 10 (hereinafter referred to as the second end) extends beyond the first end of the housing 100, allowing the user to rotate the entire atomizer bin 10 by gripping the second end.

[0048] As shown in Figures 1 and 3, the outer periphery of the second end of the atomization bin 10 may be provided with multiple raised rings 14. The multiple raised rings 14 give the outer periphery of the second end a non-slip concave-convex structure, thereby forming a rotating operating part at the second end of the atomization bin 10. The user can rotate the entire atomization bin 10 by holding the rotating operating part.

[0049] The suction nozzle 200 is covered on the second end of the atomization bin 10, and the suction nozzle 200 has an air outlet 201 that is opposite to and connected to the atomizer 20. The atomizer 20 activated in the corresponding atomization bin 10 is replaceable, the sub-atomization bin 11 and the atomizer 20 are circumferentially distributed in the atomization bin, and the air outlet 201 of the suction nozzle 200 is set off the center on the suction nozzle 200, directly opposite to the connection area on the rotating base 30. The detachable setting of the suction nozzle 200 on the atomization bin 10 is convenient for rotating the atomization bin 10 to replace the atomizer 20 and connect it to the connection area of ​​the rotating base 30. The suction nozzle 200 can be put back on the atomization bin 10 after replacing the atomizer 20, ensuring that the air outlet 201 is opposite to the connection area and is connected to the replaced sub-atomization bin 11 and the atomizer 20.

[0050] As a detachable installation method, the suction nozzle 200 can be covered on the second end of the atomization bin 10 through a concave-convex matching structure. Referring to Figures 1 and 8, in an optional embodiment, the concave-convex matching structure may include a matching movable convex buckle 204 and a buckle groove 13; the suction nozzle 200 is matched with its side wall in the second end of the atomization bin 10, and the outer surface of the side wall of the suction nozzle 200 and the inner wall surface of the second end of the atomization bin 10 are respectively provided with a movable convex buckle 204 and a buckle groove 13. The suction nozzle 200 is connected to the atomization bin 10 or removed from the atomization bin 10 by matching or separating the movable convex buckle 204 and the buckle groove 13.

[0051] The positions of the movable protrusion 204 and the buckle groove 13 can be interchanged on the suction nozzle 200 and the atomization chamber 10 .

[0052] When the electronic atomizer device is in use, or after the atomizer 20 is replaced, the nozzle 200 needs to be positioned after being placed on the atomizer bin 10 to prevent it from rotating during use. To this end, a rotation-stopping structure can be provided between the nozzle 200 and the atomizer bin 10 to prevent the nozzle 200 from rotating. The rotation-stopping structure includes, but is not limited to, a concave-convex fitting structure, a snap-fit ​​assembly, a buckle assembly, etc.

[0053] In one embodiment, referring to FIG5 , the anti-rotation structure is provided between the suction nozzle 200 and the positioning rod 50 , the positioning rod 50 is provided with a non-circular insertion hole, and the suction nozzle 200 is provided with a non-circular insertion end corresponding to the non-circular insertion hole.

[0054] In one embodiment, the electronic atomization device includes a positioning rod 50 , a positioning bracket 60 and a reset elastic member 70 .

[0055] A positioning bracket 60 is disposed within the second end of the housing 100, and the battery cell 300 and the control assembly 400 are positioned within the second end of the housing 100 via the positioning bracket 60. The control assembly 400 may further include a circuit board and a pneumatic switch (e.g., a microphone). Both the battery cell 300 and the control assembly 400 may be implemented using existing technologies and will not be further described herein.

[0056] The positioning rod 50 is disposed in the center of the atomizer chamber 10. One end is detachably connected to the nozzle 200, and the other end passes through the rotating base 30 and is connected to the positioning bracket 60. The resetting elastic member 70 abuts between the rotating base 30 and the positioning bracket 60, providing a restoring force to drive the rotating base 30 to return to its original position after movement.

[0057] Taking the vertical placement of the electronic atomization device shown in Figures 1 and 2 as an example, the positioning bracket 60 is also supported below the rotating base 30 in the housing 100. The positioning bracket 60 is connected with the rotating base 30 so that the rotating base 30 is fixed in the housing 100 relative to the housing 100. When the atomization bin 10 is rotated, the rotating base 30 can remain stationary, thereby realizing the replacement of the atomizer 20 thereon. Specifically, in combination with Figures 1, 2 and 9, the positioning bracket 60 may be provided with at least one limiting column 61 protruding toward the rotating base 30, and the rotating base 30 is provided with at least one through hole 36, which is arranged corresponding to the limiting column 61. In the housing 100, the positioning bracket 60 is inserted into the through hole 36 with its limiting column 61, thereby limiting the rotation of the rotating base 30 relative to the positioning bracket 60.

[0058] For the connection of the positioning rod 50, a central channel 15 can be defined in the atomization chamber 10 by a partition, which is isolated from the sub-atomization chamber 11, as shown in Figures 4 and 5. The positioning rod 50 is arranged in the central channel 15, with its two ends extending out of the two ends of the central channel 15 respectively.

[0059] Regarding the connection between the positioning rod 50 and the suction nozzle 200, as an option, a first positioning post 202 may be provided on the side of the suction nozzle 200 facing the positioning rod 50. The first positioning post 202 is inserted into the end of the positioning rod 50 facing the suction nozzle 200, thereby connecting the suction nozzle 200 to the positioning rod 50. As shown in Figures 3 and 5, in order to limit the rotation of the suction nozzle 200 relative to the positioning rod 50, a concave-convex matching structure is provided between the suction nozzle 200 and the positioning rod 50. The concave-convex matching structure may include a rib 203 protruding from the side of the first positioning post 202 and a slot 51 provided on the end of the positioning rod 50. The rib 203 is fitted into the slot 51 to limit the rotation of the suction nozzle 200 relative to the positioning rod 50.

[0060] It is understandable that the concave-convex matching structure is not limited to the above-mentioned slot 51 and the insert 203, and can also be grooves and protrusions of any other shape.

[0061] Regarding the connection between the positioning rod 50 and the positioning bracket 60, referring to Figures 1, 3, and 9, the positioning bracket 60 may be provided with a second positioning post 62 extending toward the positioning rod 50. The end of the positioning rod 50 facing the positioning bracket 60 is inserted into the second positioning post 62. For further securement, a fastener 80 may be inserted into the second positioning post 62 and locked into the end of the positioning rod 50, thereby securing the positioning bracket 60 and the positioning rod 50 relative to each other. The fastener 80 may be a screw or bolt. During installation, the fastener 80 is inserted into the second positioning post 62 from the side of the positioning bracket 60 facing away from the positioning rod 50 and locked into the end of the positioning rod 50 in the second positioning post 62 through threaded engagement.

[0062] The resilient reset member 70 may be a spring, with its ends respectively contacting the rotating base 30 and the positioning bracket 60. In conjunction with the second positioning post 62 on the positioning bracket 60, the resilient reset member 70 is sleeved around the outer periphery of the second positioning post 62, contacting between the surface of the rotating base 30 facing the positioning bracket 60 and the surface of the positioning bracket 60 facing the rotating base 30.

[0063] When the rotating atomization chamber 10 causes the protrusion 12 to engage with the slot 33 from the annular step 32, the reset elastic member 70 stretches from the compressed state, and also provides a restoring force to drive the rotating base 30 to move toward the atomization chamber 10, driving the power supply electrode 40 on the rotating base 30 to approach the atomizer 20 currently facing it, and conductively connect with the lead of the atomizer 20.

[0064] When the rotating atomization chamber 10 causes the protrusion 12 to move from the slot 33 to the annular step 32 , the rotating base 30 moves away from the atomization chamber 10 , driving the power supply electrode 40 on the rotating base 30 to separate from the atomizer 20 originally conductively connected, while compressing the reset elastic member 70 .

[0065] When the electronic atomizer device of the present application is used, when one atomizer 20 is used up and needs to be replaced with another atomizer 20, the nozzle 200 is removed from the atomizer chamber 10, and the rotating atomizer chamber 10 drives the atomizer 20 inside it to rotate. While the atomizer chamber 10 rotates, it also moves away from the rotating base 30, driving the power supply electrode 40 on the rotating base 30 to retreat to prevent it from being scratched by the atomizer chamber 10 and other structures. The atomizer chamber 10 is rotated by a required angle (for example, 90°, 180° or 270°) to place another atomizer 20 on the connection area of ​​the rotating base 20, while also driving the atomizer chamber 10 to move towards the rotating base 30. The atomizer 20 contacts the power supply electrode 40 for conductive connection. After the atomizer 20 is conductively connected to the control component 400 and the atomization channel of the atomizer 20 is connected to the air inlet 31 through the power supply electrode 40, the nozzle 200 is put back on the atomizer chamber 10. The user can activate the electronic atomization device by inhaling and triggering the pneumatic switch.
