[0046] One embodiment of the present application provides an electronic atomization device 100 for atomizing a liquid matrix to generate an aerosol. As shown in Figures 1 and 2, the electronic atomization device 100 includes a mouthpiece 10, a housing 20, and a base 30. The housing 20 has a first end 21 and a second end 22 disposed opposite each other in a longitudinal direction. The mouthpiece 10 is connected to the first end 21 of the housing 20. The mouthpiece 10 is provided with an air outlet 11 for allowing the aerosol to escape from the electronic atomization device 100. The user can inhale the aerosol by inhaling at the air outlet 11. The base 30 is connected to the second end 22 of the housing 20, and at least a portion thereof extends into the housing 20 to provide support for the components in the housing 20.

[0047] As shown in Figures 3 and 4, a first rotating member 21 is provided in the shell 20. The first rotating member 21 includes a plurality of plate-like bodies 211 that are spaced apart and extend longitudinally. The plurality of plate-like bodies 211 are arranged circumferentially around the longitudinal axis L1 of the first rotating member 21. A chamber 2111 is formed between any two adjacent plate-like bodies 211. An atomizer 212 is fixedly provided in each chamber 2111, so that the plurality of atomizers 212 surround the longitudinal axis L1 of the first rotating member 21. The first rotating member 21 and the plurality of atomizers 212 are combined to form an atomization component of the electronic atomization device 100, and the atomization component is used to atomize the liquid matrix to generate an aerosol.

[0048] As shown in Figures 3 and 5, the atomizer 212 is provided with a liquid storage chamber, which is filled with a liquid storage member 2121. The liquid storage member 2121 is made of a hygroscopic material so that the liquid storage member 2121 is soaked in an atomizable liquid matrix. In some embodiments, the composition of the liquid matrix stored in each atomizer 212 can be different, so that the aerosol formed after atomization has different flavors. The liquid storage part 2121 is formed with an axially penetrating through hole 2122, and a rigid air guide tube 2123 is provided in the through hole 2122. The air guide tube 2123 is provided with an atomizing element 2124. The atomizing element 2124 is used to receive the liquid matrix in the liquid storage part 2121 and atomize the liquid matrix to form an aerosol and release it into the air guide tube 2123. At the same time, the mouthpiece 10 is provided with an air flow channel 12, which connects the air guide tube 2123 and the air outlet 11, so that the aerosol in the air guide tube 2123 can flow to the air outlet 11 through the air flow channel 12.

[0049] The atomizing element 2124 includes a liquid-conducting element 21241 and a heating element 21242 coupled to the liquid-conducting element 21241. The liquid-conducting element 21241 is provided with an axially extending through-hole 21243, thereby forming an outer wall and an inner wall. The heating element 21242 is coupled to the inner wall. Furthermore, a through-hole 2125 is provided in the wall of the air-conducting tube 2123. A portion of the liquid-conducting element 21241 passes through the through-hole 2125 and contacts the liquid storage element 2121. The liquid-conducting element 21241 is also made of a hygroscopic material. Thus, the liquid-conducting element 21241 can absorb liquid matrix infiltrated into the liquid storage element 2121 and transfer the liquid matrix to the heating element 21242. The heating element 21242 then heats and atomizes the liquid matrix, thereby forming an aerosol.

[0050] The liquid storage element 2121 and the liquid conducting element 21241 can be made of flexible fibers, such as cotton fibers, non-woven fabrics, glass fiber ropes, etc., or can be made of porous materials with microporous structures, such as porous ceramics, so that the liquid matrix can be transferred through the internal voids or microporous structures of the liquid storage element 2121 and the liquid conducting element 21241. Accordingly, the heating element 21242 can be combined with the liquid conducting element 21241 by printing, deposition, sintering, or physical assembly, or can be wound around the liquid conducting element 21241.

[0051] As shown in Figures 2, 6 and 7, a second rotating member 31 is assembled on the base 30, and the second rotating member 31 can be manually operated by the user. The second rotating member 31 includes a base 311, and the base 311 has an end face 3111. A plug-in hole 3112 extends from the end face 3111 toward the first rotating member 21, and a card slot 3113 is formed on the hole wall of the plug-in hole 3112. The first rotating member 21 extends a plug-in portion 2126 toward the second rotating member 31, and a snap portion 21261 is provided on the plug-in portion 2126. The plug-in portion 2126 is plugged into the plug-in hole 3112, and the snap portion 21261 on the plug-in portion 2126 is snap-connected with the card slot 3113, thereby fixing the first rotating member 21 and the second rotating member 31 together.

[0052] The side of the end surface 3111 facing away from the plug hole 3112 is divided into a first part 31151 and a second part 31152. The first part 31151 and the second part 31152 provide an avoidance space to facilitate the user to manually operate the operating part 3114. The user can operate the operating part 3114 to rotate the second rotating part 31, and the rotation of the second rotating part 31 thereby drives the first rotating part 21 to rotate synchronously.

[0053] As shown in Figures 3, 8, and 9, a support member 40 is provided between the base 30 and the first rotating member 21. The support member 40 has a support surface 41 for providing support for the first rotating member 21. The end surface of the first rotating member 21 opposite the support member 40 is provided with a number of latching protrusions 2127, the same number as the atomizers 212. The latching protrusions 2127 abut against the support surface 41, so that the support surface 41 provides support for the first rotating member 12. When the second rotating member 31 is operated by a user to rotate, the second rotating member 31 drives the first rotating member 21 to rotate synchronously, thereby causing the latching protrusions 2127 to rotate on the support surface 41.

[0054] As further shown in Figures 10 and 11, an electrical connection terminal 42 is provided on the support member 40, and the electrical connection terminal 42 is used to be electrically connected to the conductive electrode 2128 of the atomizer 212, so as to conduct the electric energy required for heating and atomization to the atomizer 212. In order to improve the reliability of the electrical connection, the electrical connection terminal 42 preferably adopts a spring thimble. Since the first rotating member 21 is rotatable, any atomizer 212 can be rotated to a preset position by rotating the first rotating member 21, so that the electrical connection terminal 42 can be electrically connected to any atomizer 212. The electronic atomization device 100 also includes a battery cell 50 and a main board (not shown in the figure). The battery cell 50 and the electrical connection terminal 42 are both electrically connected to the main board. The main board is provided with a controller of the electronic atomization device 100, so that the controller can control the battery cell 50 to provide electric energy to the atomizer 212 through the electrical connection end 42.

[0055] In some embodiments, as shown in FIG12 , the support surface 41 is provided with a plurality of grooves 411 that are the same number as the latching protrusions 2127 , and the plurality of grooves 411 are spaced apart. When the electronic atomization device 100 is in normal use, the plurality of latching protrusions 2127 are correspondingly snapped into the grooves 411 , and the electrical connection terminal 42 is now electrically connected to the conductive electrode 2128 of one of the atomizers 212 , so that the battery cell 50 provides electrical energy to the atomizer 212 . When the liquid matrix in the atomizer 212 is consumed, or the user needs to change to an aerosol of a different flavor, the second rotating member 31 can be rotated to drive the first rotating member 21 to rotate, thereby causing the other atomizer 212 to maintain electrical connection with the electrical connection terminal 42 , thereby causing the atomizer 212 to start working.

[0056] Furthermore, in some embodiments, as shown in FIG12 , the support surface 41 is further provided with a protrusion 412 adjacent to the groove 411. When the latching protrusion 2127 rotates along the support surface 41 and approaches the groove 411, the latching protrusion 2127 first contacts the protrusion 412, and the latching protrusion 2127 and the protrusion 412 generate a damping interference, that is, the protrusion 412 provides a damping effect on the latching protrusion 2127. Since the first rotating member 21 is driven to rotate by the second rotating member 31, the damping effect is further transmitted to the second rotating member 31, and the user can feel the damping effect caused by the damping effect. By perceiving the damping effect, the user can determine that the first rotating member 21 is about to rotate to the predetermined position. Preferably, the protrusion 412 is provided on both sides of the groove 411, so that the user can feel the damping effect regardless of whether the user rotates the second rotating member 31 in the clockwise or counterclockwise direction.

[0057] It should be noted that the locking protrusion 2127 and the groove 411 form a locking mechanism, which is used to lock the first rotating member 21 or the second rotating member 31 when the second rotating member 31 is in the first position, thereby restricting its rotation; and to release the lock when the second rotating member 31 is in the second position, thereby allowing the second rotating member 31 to drive the first rotating member 21 to rotate relative to the electrical connection terminal 42. It is easy to understand that in other embodiments, the locking mechanism can also adopt other implementation methods well known to those skilled in the art, so long as the second rotating member 31 is restricted in rotation when it is in the first position and released in the second position to allow the second rotating member 31 to rotate.

[0058] In some embodiments, the second rotating member 31 is configured to rotate by pressing. That is, the user first presses the second rotating member 31 to allow the second rotating member 31 to move from a first position to a second position in the longitudinal direction relative to the housing 20. Since the second rotating member 31 is fixedly connected to the first rotating member 21, the second rotating member 31 will simultaneously drive the first rotating member 21 to move in the longitudinal direction when it moves in the longitudinal direction. When the second rotating member 31 moves to the second position, the first rotating member 21 moves in the longitudinal direction, causing the locking protrusion 2127 of the first rotating member 21 to disengage from the groove 411. After the locking protrusion 2127 is disengaged from the groove 411, the user can rotate the second rotating member 31. The rotation of the second rotating member 31 will synchronously drive the rotation of the first rotating member 21 to switch between different atomizers 212 and the electrical connection terminal 42 for electrical connection.

[0059] When the protrusion 2127 is disengaged from the groove 411, the electrical connection terminal 42 and the conductive electrode 2128 of the atomizer 212 are also separated from each other. That is, when the second rotating member 31 is in the second position, the electrical connection terminal 42 and the conductive electrodes 2128 of the multiple atomizers 212 are separated, thereby preventing the electrical connection terminal 42 and the conductive electrodes 2128 of the atomizers 212 from contacting each other during the rotation of the first rotating member 21. If the electrical connection terminal 42 and the conductive electrodes 2128 of the atomizers 212 come into contact with each other during the rotation, the electrical connection terminal 42 and the conductive electrodes 2128 of the atomizers 212 will produce a certain amount of wear over the long-term use of the electronic atomization device 100, thereby reducing the reliability of the electrical connection. Such wear can be avoided by the method of this embodiment. When the second rotating member 31 is in the first position, only the conductive electrode 2128 of one atomizer 212 is electrically connected to the electrical connection terminal 42.

[0060] Therefore, when the user needs to switch the atomizer 212, he only needs to operate the second rotating member 31 to press it to the second position first, so that the locking protrusion 2127 on the first rotating member 21 is disengaged from the groove 411, and then operate the second rotating member 31 to rotate to switch the atomizer 212, thereby electrically connecting the electrical connection terminal 42 and the conductive electrode 2128 of different atomizers 212. In this way, the structural design of switching the atomizer 212 can be simplified and the operation is also simple.

[0061] In some embodiments, the electronic atomization device 100 includes a first elastic member and a second elastic member. The first elastic member is used to be squeezed by the first rotating member 21 when the first rotating member 21 is displaced in the longitudinal direction, thereby providing a buffer space for the first rotating member 21 to move in the longitudinal direction. The first elastic member can also reset the first rotating member 21 in the longitudinal direction, so that the first rotating member 21 returns to and remains in the initial position. Similarly, the second elastic member is used to be squeezed by the second rotating member 31 when the second rotating member 31 is displaced in the longitudinal direction, thereby providing a buffer space for the second rotating member 31 to move in the longitudinal direction. The second elastic member can also reset the second rotating member 31 in the longitudinal direction, that is, the second elastic member drives the second rotating member 31 to return from the second position and remain in the first position.

[0062] Specifically, as shown in FIG3 , the first elastic member includes an elastic seal 14 disposed within the mouthpiece 10. The elastic seal 14 can be made of a flexible material such as silicone or rubber. The mouthpiece 10 includes a housing 13 having a first end and a second end disposed opposite each other. The first end is provided with an air outlet 11, and the second end is open and defines a chamber 131. The airflow channel 12 extends into the chamber 131. The elastic seal 14 is interference-fitted within the chamber 131 and surrounds the airflow channel 12, thereby sealing the airflow channel 12 and directing the aerosol formed after atomization to the air outlet 11. The atomizer 212 of the first rotating member 21 abuts against the elastic seal 14, and when the first rotating member 21 is displaced in the longitudinal direction, the first rotating member 21 will squeeze the elastic seal 14, and the elastic seal 14 will then deform to provide a buffer space for the movement of the first rotating member 21. When the atomizer 212 is switched and the user is no longer operating the second rotating member 31, the elastic seal 14 restores its elastic deformation, and the first rotating member 21 is reset in the longitudinal direction under the elastic restoring force of the elastic seal 14.

[0063] Also, in some embodiments, please continue to refer to Figure 3, the first elastic member also includes a compression spring 15 arranged in the chamber 131, one end of the compression spring 15 abuts against the inner wall of the chamber 131, and the other end abuts against the elastic seal 14, so that when the first rotating member 21 is displaced in the longitudinal direction, the first rotating member 21 first squeezes the elastic seal 14 to cause the elastic seal 14 to deform, and the elastic seal 14 further squeezes the compression spring 15 to cause the compression spring 15 to deform, and then by adding the compression spring 15, the elastic restoring force on the first rotating member 21 will be further increased, which facilitates the first rotating member 21 to reset in the longitudinal direction.

[0064] Further, in some embodiments, please continue to refer to Figure 3, the airflow channel 12 is defined by an airway tube extending into the chamber 131, and the compression spring 15 is arranged around the airway tube to limit the compression spring 15 to prevent the compression spring 15 from shifting during the compression process, thereby affecting the resetting of the first rotating member 21.

[0065] In some embodiments, as shown in Figure 3, the support member 40 is formed with a chamber 43, and at least a portion of the second rotating member 31 extends into the chamber 43. The chamber 43 is also provided with a plate-shaped body 44 supported on the second rotating member 31, and the second elastic member includes a compression spring 45 elastically abutting between the plate-shaped body 44 and the inner wall of the chamber 43, so that when the second rotating member 31 is displaced in the longitudinal direction, the second rotating member 31 squeezes the compression spring 45 to cause the compression spring 45 to deform, thereby increasing the buffer space for the displacement of the second rotating member 31 in the longitudinal direction. When the user releases the operation of the second rotating member 31, the compression spring 45 restores the deformation and resets the second rotating member 31 in the longitudinal direction under the action of the elastic recovery force.

[0066] Furthermore, in some embodiments, as shown in FIG. 3 , a compression spring 45 is disposed around the plug-in portion 2126 of the first rotating member 31 to limit the compression spring 45 and prevent the compression spring 45 from shifting during compression, thereby affecting the resetting of the second rotating member 21 .

[0067] It should be noted that the method by which the nebulizer 212 atomizes the liquid matrix to generate an aerosol is not limited to that described in the above embodiment. Those skilled in the art may also use other well-known heating atomization methods to atomize the liquid matrix to generate an aerosol. Furthermore, in some embodiments, the nebulizer 212 may also use ultrasonic atomization to atomize the liquid matrix to generate an aerosol.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Based on the concept of the present application, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations in different aspects of the present application as described above. For the sake of simplicity, they are not provided in detail.
