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

[0042] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] like Figures 1 to 4 As shown, the electronic atomization device according to the embodiment of the present invention includes a battery rod 10, an atomization assembly 20 and a switching assembly 30, the battery rod 10 includes a housing 11, a mounting bracket 12 arranged in the housing 11 and a power supply 13 fixed in the mounting bracket 12; the atomization assembly 20 includes an atomizer bracket 21 rotatably arranged at the top of the mounting bracket 12, at least two atomizers 22 arranged in the atomizer bracket 21, and at least two atomizers 22 are evenly distributed along the central axis of the atomizer bracket 21; the switching assembly 30 includes a driving gear 31 and a driven gear 32 rotatably arranged in the mounting bracket 12, the driven gear 32 rotates synchronously with the atomizer bracket 21, and the driving gear 31 can drive the driven gear 32 to rotate, so that the power supply 13 can selectively be electrically connected to any one of the atomizers 22. In order to facilitate the description of the technical solution of the present invention, in this embodiment, the position of the atomizer 22 in an electrically connected state is set as the working position, and the positions of the other atomizers 22 are all non-working positions.

[0044] When the electronic atomization device of this embodiment is in use, different atomization media are stored in each atomizer 22 respectively. The atomizer bracket 21 can be driven to rotate a certain angle as needed to switch different atomizers 22 to perform a single task. Specifically, when the user needs to use a certain atomizer 22 (i.e., the target atomizer 22), power can be input by turning the active gear 31, and the driven gear 32 can be driven to rotate, thereby driving the atomizer bracket 21 to rotate until the target atomizer 22 moves to the working position. At this time, the target atomizer 22 is electrically connected to the power supply 13, thereby realizing the switching of different atomizers 22. The operation is convenient and quick, avoiding the trouble of carrying multiple atomizers 22 and the need to disassemble and assemble the atomizer 22, and greatly improving the user experience.

[0045] It should be noted that a controller (not shown) is also provided in the mounting bracket 12, and the controller is electrically connected to the power supply electrode 122 and the power supply 13, and is used to control whether the power supply 13 supplies power to the atomizer 22 in the working position according to the actual control signal. In addition, the rotation of the driving gear 31 can be achieved in a variety of ways. In this embodiment, at least a portion of the driving gear 31 protrudes from the housing 11, and the power output is achieved by the user manually turning the driving gear 31. In other embodiments, a servo motor can also be provided in the mounting bracket 12 to drive the driving gear 31.

[0046] In this specific embodiment, Figure 4 and Figure 5 As shown, the atomizer 22 also includes two conductive electrodes 221, one end of the two conductive electrodes 221 is electrically connected to the atomizing core inside the atomizer 22, and the other end is penetrated through the bottom wall of the atomizer 22 and exposed on the outer surface of the bottom wall; it should be understood that the atomizing core of the atomizer 22 includes a conductive liquid and a heating element attached to the conductive liquid, the two ends of the heating element are electrically connected to the two conductive electrodes 221 respectively, the liquid storage cavity in the atomizer 22 is connected to the conductive liquid, the atomizing medium in the liquid storage cavity can be transmitted to the conductive liquid, and when the atomizer 22 is powered on, the heating element can heat and atomize the atomizing medium in the conductive liquid to generate an aerosol that can be inhaled.

[0047] A mounting portion 121 is formed at the top of the mounting bracket 12, and two power supply electrodes 122 are arranged on the mounting portion 121. The two power supply electrodes 122 are electrically connected to the power supply 13. The atomizer bracket 21 can be rotatably mounted on the mounting portion 121, and selectively make the two conductive electrodes 221 of one of the atomizers 22 electrically connected to the two power supply electrodes 122 one by one.

[0048] Preferably, the upper surface of the power supply electrode 122 is flush with the upper surface of the mounting portion 121, and the power supply electrode 122 and / or the conductive electrode 221 are magnetic or ferromagnetic. Therefore, by setting the power supply electrode 122 and / or the conductive electrode 221 as a magnetic or ferromagnetic structure, the atomizer assembly 20 can be rotated at a certain angle or the target atomizer 22 can be stably positioned at the working position, so that the two conductive electrodes 221 of the atomizer 22 are electrically connected to the two power supply electrodes 122 one by one.

[0049] In addition, the stable connection method between the atomizer 22 and the two conductive electrodes 221 is not limited to the above-mentioned embodiment, and can also be achieved by making the power supply electrode 122 slightly higher than the top surface of the mounting portion 121, so that the two conductive electrodes 221 of the atomizer 22 can be electrically contacted with the two power supply electrodes 122 after the atomization assembly 20 is rotated; or the two power supply electrodes 122 adopt a spring electrode (pogo pin connector) structure.

[0050] Furthermore, the mounting portion 121 forms an air inlet channel 123 between the two power supply electrodes 122, and an air inlet hole 222 is formed at the bottom of the atomizer 22. When one atomizer 22 is in the working position and electrically connected to the power supply 13, the air inlet hole 222 of the atomizer 22 is correspondingly connected to the air inlet channel 123, while the bottom air inlet holes 222 of other atomizers 22 are blocked by the mounting portion 121, thereby ensuring that when the user inhales, the air entering from the outside through the air inlet channel 123 can only enter from the air inlet hole 222 at the bottom of the atomizer 22 in the working position, and after mixing with the aerosol generated by the atomization core, it is inhaled by the user.

[0051] In one embodiment, the electronic atomization device of the embodiment of the present invention further includes a positioning assembly, which includes a first magnetic member (not shown) disposed on the mounting portion 121 and a second magnetic member (not shown) disposed on the bottom wall of the atomizer 22. When the first magnetic member is adsorbed to the second magnetic member on one of the atomizers 22, the conductive electrode 221 of the atomizer 22 is electrically connected to the power supply electrode 122. It should be understood that each atomizer 22 is provided with a second magnetic member on the bottom wall, and whenever the atomizer bracket 21 is rotated a certain angle (for example, the second magnetic member is attached to the bottom wall of the atomizer 22). Figure 4 The structure shown in the figure is rotated 120°), in which the second magnetic part of one atomizer 22 is adsorbed on the first magnetic part. At this time, the atomizer 22 is in the working position, and its air inlet hole 222 is correspondingly connected to the air inlet channel 123, and its two conductive electrodes 221 are respectively in one-to-one contact with the two power supply electrodes 122; therefore, by providing the first magnetic part and the second magnetic part, it is possible to facilitate the rapid positioning of different atomizers 22 during switching, and improve the connection stability between the conductive electrode 221 and the power supply electrode 122.

[0052] In one embodiment, the battery rod 10 further includes a pneumatic switch (not shown) disposed in the mounting bracket 12, a sensing channel 124 connected to the sensing cavity where the pneumatic switch is located is formed in the mounting portion 121, and a sensing hole 223 is formed at the bottom of the atomizer 22. When an atomizer 22 is electrically connected to the power supply 13, the sensing hole 223 of the atomizer 22 is correspondingly connected to the sensing channel 124. It should be noted that the atomization channel in the atomizer 22 is respectively connected to the air inlet 222 and the sensing hole 223, and the pneumatic switch is electrically connected to the controller. When the user inhales, negative pressure is generated in the sensing cavity to trigger the pneumatic switch to generate a signal, so that the controller controls the power supply 13 to supply power to the atomizer 22 in the working position according to the signal, thereby heating and generating aerosol, so as to realize the automatic suction operation of the atomizer 22.

[0053] In this embodiment, a mounting through hole 125 is provided at the center of the mounting portion 121, and a connecting rod 211 is formed at the center of the bottom end of the atomizer bracket 21, which protrudes downward. The connecting rod 211 passes through the mounting through hole 125 and is fixedly connected to the driven gear 32. The driving gear 31 and the driven gear 32 are directly meshed spur gear structures, which can make the structure more compact and reliable. Of course, in other embodiments, a transmission gear or a transmission gear set can be set between the driving gear 31 and the driven gear 32 according to actual needs for transmission connection, so that the driving gear 31 and the driven gear 32 are indirectly meshed through the transmission gear or the transmission gear set, so that the force required to turn the driving gear 31 is not too large and difficult to turn.

[0054] Furthermore, a through hole 212 corresponding to the number of the atomizers 22 and penetrating up and down is formed in the atomizer bracket 21, and the plurality of through holes 212 are evenly distributed in a circle relative to the central axis of the connecting rod 211, and the lower end of each atomizer 22 is installed in each through hole 212 in a one-to-one correspondence. The atomizer 22 is installed by providing an installation cavity formed by the through holes 212, so that each atomizer 22 can be installed in a plug-in manner, which is convenient for fixing and disassembling the atomizer 22 and improving the convenience of replacing the atomizer 22.

[0055] In one embodiment, in combination Figure 6 and Figure 7As shown, the electronic atomization device of the embodiment of the present invention also includes a cup body 40, which is covered on the outside of the atomization assembly 20 and connected to the housing 11. The end of the cup body 40 away from the housing 11 is integrally formed or installed with a suction nozzle 41, and the suction nozzle 41 is connected to the air outlet 224 of each atomizer 22 through a silicone sleeve 50. The above structure can protect the atomization assembly 20 in the cup body 40, and at the same time, the cup body 40 and the silicone sleeve 50 are used to form a waterproof structure to prevent the electronic components in the battery rod 10 from short-circuiting or even burning due to moisture or rainwater immersion. In other embodiments, the cup body 40 can also be formed integrally with the housing 11. At this time, the lower half of the housing 11 can be formed by splicing the left and right shells. When installing, the atomization assembly 20, the silicone sleeve 50 and the mounting bracket 12 are first assembled into a whole, and then the whole is inserted upward from the lower end of the housing to achieve installation.

[0056] Furthermore, the top of each atomizer 22 extends into and is fixed in the silicone sleeve 50, and a connecting portion 51 connected to the suction nozzle 41 is formed at the top of the silicone sleeve 50. The suction nozzle 41 is connected to the air outlet 224 of each atomizer 22 through the connecting portion 51. Specifically, the suction nozzle 41 extends inward to form a connecting tube 42, and the connecting portion 51 can be rotatably sleeved on the connecting tube 42. With such a structure, no matter how the atomizer assembly 20 rotates, the air outlet 224 of each atomizer 22 can be kept in a connected state with the suction nozzle 41.

[0057] Furthermore, the bottom of the silicone sleeve 50 is formed with accommodating cavities 52 corresponding to the number of the atomizers 22, the top of the atomizer 22 is installed in the accommodating cavity 52, and air passages 53 are respectively formed between each accommodating cavity 52 and the connecting portion 51. In other words, through the arrangement of the silicone sleeve 50, the air outlet 224 of the atomizer 22 can be connected only to the suction nozzle 41, ensuring the suction force generated by the user on the atomizer 22 in the working position when inhaling.

[0058] In one embodiment, the protruding portion of the driving gear 31 when each atomizer 22 is electrically connected to the power supply 13 is respectively provided with a distinguishing mark. Exemplarily, a plurality of gear teeth evenly spaced on the driving gear 31 are respectively provided with different colors, each color corresponds to an atomizer 22, and when the driving gear 31 rotates to expose the gear teeth of one color to the housing 11, the corresponding atomizer 22 rotates to the working position. For another example, a plurality of gear teeth evenly spaced on the driving gear 31 are respectively depicted with anti-slip stripes of different densities, each anti-slip stripe of one density corresponds to an atomizer 22, and when the driving gear 31 rotates to expose the gear teeth of one density anti-slip stripe to the housing 11, the corresponding atomizer 22 rotates to the working position. In this way, by setting a distinguishing mark, the user can clearly and directly know which atomizer 22 is currently in the working position, thereby improving the user's experience.

[0059] In another embodiment, in combination Figure 8 As shown, the main difference between the electronic atomization device of this embodiment and the above embodiment lies in the structure of the switching component 30. Specifically, the switching component 30 of this embodiment also includes a rotating shaft 33, and the driving gear 31 and the driven gear 32 are mutually meshing bevel gears. The driven gear 32 is fixed on the connecting rod 211 of the atomizer bracket 21. The rotating shaft 33 can be rotatably mounted on the mounting bracket 21, one end of which is synchronously rotated and connected with the driving gear 31, and the other end extends out of the battery rod 10 and forms a driving part 331. Through such a structure, when the user needs to switch a certain atomizer 22 for use, the driving part 331 can be rotated to input power to rotate the rotating shaft 33, and drive the driving gear 31 and the driven gear 32 to rotate, thereby driving the atomizer bracket 21 to rotate until the target atomizer 22 rotates to the working position. At this time, the target atomizer 22 is electrically connected to the power supply 13, and the target atomizer 22 works alone to generate aerosol after the user inhales.

[0060] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
