Unless otherwise specified, "connection" and "coupling" in this application include direct and indirect connections (couplings).

[0036] In an embodiment of the application, an atomization assembly 10 is provided, which is applied to an atomization device. The atomization assembly 10 is used to heat and atomize the liquid to be atomized stored in the atomization device. After the liquid to be atomized is heated and atomized, it becomes a state that can be inhaled by a user, for example, an aerosol that can be inhaled by a user.

[0037] Referring to Figures 1-7 , the atomization assembly 10 comprises an inner liquid guide 11, an outer liquid guide 12, and an atomization support 13.

[0038] The outer liquid guide 12 is sleeved on the outer side of the inner liquid guide 11.

[0039] The atomization support 13 is axially divided into a first support 131 and a second support 132, the first support 131 is sleeved between the inner liquid guide 11 and the outer liquid guide 12, the second support 132 is provided with a liquid injection hole 133 on the side close to the first support 131, and the inner liquid guide 11 and the outer liquid guide 12 are communicated through the liquid injection hole 133.

[0040] The atomization assembly 10 in the above embodiment can pre-inject any one of the inner liquid guide 11 and the outer liquid guide 12 during pre-injection, and then the injected to-be-atomized liquid is distributed on both the inner liquid guide 11 and the outer liquid guide 12 through the liquid injection hole 133, so that the inner liquid guide 11 and the outer liquid guide 12 are both injected, which better guarantees the working state of the atomization assembly 10 and also better guarantees the working state of the atomization device containing the atomization assembly 10.

[0041] When the atomization assembly 10 designed in the present application is pre-injected, for example, pre-injected by a syringe needle, any one of the inner liquid guide 11 or the outer liquid guide 12 can be pre-injected, but it should be noted that the syringe needle is preferably placed on the outer side of the corresponding liquid guide, for example, when the inner liquid guide 11 is injected, as shown in Figure 1 , the syringe needle is placed above the inner liquid guide 11, the to-be-atomized liquid drops into the inner liquid guide 11, and the excess to-be-atomized liquid on the inner liquid guide 11 can overflow to the top surface of the outer liquid guide 12 through the liquid injection hole 133, and then be absorbed by the outer liquid guide 12, realizing the pre-injection operation of the inner liquid guide 11 and the outer liquid guide 12.

[0042] Referring to Figures 1-6 , the inner liquid guide 11 and the outer liquid guide 12 are both annular columns, and the atomization support 13 is a pipe. The atomization assembly 10 further comprises a heating element 14, the heating element 14 is fixed to the inner wall of the inner liquid guide 11, and the heating element 14 is used for heating the to-be-atomized liquid on the inner wall of the inner liquid guide 11. The heating element 14 can be a mesh, a sheet, a wire, or other resistance structures.

[0043] Referring to Figures 3-4The injection holes 133 are configured in multiple, for example, the injection holes 133 are configured in 2, 3, 4, etc., and the multiple injection holes 133 are arranged around the axis of the atomization support 13. When injecting, taking the injection of the inner liquid guide 11 as an example, when the injection holes 133 are configured in multiple and arranged at equal intervals around the axis of the atomization support 13, the excess atomized liquid of the inner liquid guide 11 can be synchronously overflowed to the outer liquid guide 12 through the multiple injection holes 133, thereby providing a more uniform pre-injection effect to different positions of the outer liquid guide 12.

[0044] Please refer to Figure 1 and Figure 4 The dashed line in the figure is the dividing line of the first support 131 and the second support 132 in the atomization support 13, part of the injection holes 133 extend to the first support 131 to communicate the inner liquid guide 11 and the outer liquid guide 12 on both sides of the first support 131, and one end of the inner liquid guide 11 towards the second support 132 is recessed towards the first support 131 relative to one end of the outer liquid guide 12 towards the second support 132.

[0045] The outer liquid guide 12 and the inner liquid guide 11 in the atomization assembly 10 are both used for absorbing and transferring the atomized liquid, based on this function, the outer liquid guide 12 and the inner liquid guide 11 can both be porous materials, for example, the outer liquid guide 12 and the inner liquid guide 11 are both liquid guide cotton. When the atomization assembly 10 is working, the atomized liquid stored in the atomization device is usually first transferred to the outer liquid guide 12, the outer liquid guide 12 absorbs the atomized liquid and then transfers the absorbed atomized liquid to the inner liquid guide 11, and then the inner liquid guide 11 absorbs the atomized liquid transferred to the inner wall of the inner liquid guide 11 for heating by the heating element 14. In the actual atomization assembly 10, the thickness of the outer liquid guide 12 is relatively smaller than the thickness of the inner liquid guide 11, therefore, in order to facilitate injection, an injection structure (such as a syringe needle) is used to first inject the inner liquid guide 11, and then the atomized liquid is overflowed from the top surface of the inner liquid guide 11 to the outer liquid guide 12 through the injection holes 133, thereby achieving the injection of the outer liquid guide 12.

[0046] Part of the injection holes 133 extend to the first support 131, so that the inner liquid guide 11 and the outer liquid guide 12 on both sides of the first support 131 are communicated, which is convenient for both the atomized liquid on the inner liquid guide 11 to be guided out to the outer liquid guide 12 through the injection holes 133 on the second support 132 during injection, and the pre-injected atomized liquid in the inner liquid guide 11 to be transferred to the outer liquid guide 12 through the injection holes 133 on the first support 131, thereby improving the efficiency of pre-injection of the inner liquid guide 11 and the outer liquid guide 12, and facilitating the transfer of the atomized liquid stored in the atomization device to the inner liquid guide 11 by the outer liquid guide 12 during the later working of the atomization assembly 10.

[0047] Please refer to Figure 1, the one end of the inner liquid guide 11 towards the second support 132 is recessed towards the first support 131 side relative to the one end of the outer liquid guide 12 towards the second support 132, i.e. the top surface of the outer liquid guide 12 is higher than the top surface of the inner liquid guide 11, so that the liquid injection effect to the inner liquid guide 11 can be guaranteed during pre-liquid injection, i.e. after injecting enough liquid to be atomized on the inner liquid guide 11, the excess liquid to be atomized on the top surface of the inner liquid guide 11 will overflow to the outer liquid guide 12 through the liquid injection hole 133. In other embodiments, the heights of the top surfaces of the outer liquid guide 12 and the inner liquid guide 11 can also be consistent or the same.

[0048] Specifically, please refer to Figure 4 In the embodiments of the present application, the liquid injection hole 133 is a strip-shaped hole, and the length direction of the strip-shaped hole is parallel or inclined to the axial direction of the atomization support 13.

[0049] More preferably, when pre-injecting liquid to the inner liquid guide 11 and the outer liquid guide 12, the liquid injection amount does not exceed half of the total volume of the inner liquid guide 11 and the outer liquid guide 12.

[0050] Please refer to Figures 3-4 The first support 131 is provided with a liquid guide hole 134, and the inner liquid guide 11 and the outer liquid guide 12 on both sides of the first support 131 are communicated through the liquid guide hole 134. The number of liquid guide holes 134 can be configured as one or more according to needs, for example, the number of liquid guide holes 134 is configured as 2. At this time, the inner liquid guide 11 and the outer liquid guide 12 on both sides of the first support 131 are not only communicated through the liquid injection hole 133, but also communicated through the liquid guide hole 134. The outer liquid guide 12 and the inner liquid guide 11 are separated by the positions on the first support 131 where the liquid injection hole 133 and the liquid guide hole 134 are not provided, so as to avoid that the conduction area between the outer liquid guide 12 and the inner liquid guide 11 is too large during the use of the atomization assembly 10 later, which causes the outer liquid guide 12 to transfer a large amount of liquid to be atomized in the atomization device to the inner liquid guide 11, resulting in the problem of liquid leakage of the inner liquid guide 11.

[0051] Please refer to Figure 3In other embodiments, the liquid injection holes 133 are strip-shaped holes, and the length direction of the strip-shaped holes is distributed along the circumferential direction of the atomization support 13. At this time, the strip-shaped holes are only distributed on the side of the second support 132 close to the first support 131, and the end of the strip-shaped hole close to the inner layer liquid guide 11 can be flush with the top surface of the inner layer liquid guide 11, or the end of the strip-shaped hole close to the inner layer liquid guide 11 is higher than the top surface of the inner layer liquid guide 11. The top surface of the outer layer liquid guide 12 can be higher, lower or flush with the top surface of the inner layer liquid guide 11. Preferably, the end of the strip-shaped hole close to the inner layer liquid guide 11 is higher than the top surface of the inner layer liquid guide 11 and the top surface of the outer layer liquid guide 12. The strip-shaped hole is relatively narrow compared to other round holes, square holes and the like, which can control the amount of liquid overflowing from the inner layer liquid guide 11 to the outer layer liquid guide 12, and avoid the phenomenon that too much liquid from the inner layer liquid guide 11 overflows to the outer layer liquid guide 12, which cannot be absorbed in time, resulting in the phenomenon that the liquid to be atomized remains in other unnecessary positions. At the same time, the length of the strip-shaped hole can be relatively long, which facilitates liquid injection to more parts of the outer layer liquid guide 12 in the circumferential direction, thereby improving the liquid injection efficiency. It can be understood that the liquid injection holes 133 on the second support 132 are configured as a plurality of liquid injection holes 133 for facilitating synchronous liquid injection to different positions of the outer layer liquid guide 12 in the circumferential direction.

[0052] Referring to Figure 1 In other embodiments, the atomization assembly 10 further comprises a support 90, which is sleeved inside the inner layer liquid guide 11 during assembly of the atomization assembly 10 or pre-liquid injection, and the support 90 is in contact with the inner wall of the inner layer liquid guide 11. The support 90 can be columnar or cylindrical, and when the support 90 is cylindrical, the bottom of the support 90 is located on the side facing the second support 132. By using the support 90 during assembly of the atomization assembly 10, the shapes of the inner layer liquid guide 11, the outer layer liquid guide 12 and the heating element 14 can be better maintained, and the deformation of the inner layer liquid guide 11, the outer layer liquid guide 12 and the heating element 14 can be avoided. During pre-liquid injection, the top end of the support 90 can be higher than the top surface of the inner layer liquid guide 11, for example, the top end of the support 90 is 1 mm higher than the top surface of the inner layer liquid guide 11, to avoid the phenomenon of liquid leakage during liquid injection into the inner layer liquid guide 11. After pre-liquid injection or assembly of the atomization assembly 10 is completed, the support 90 can be removed.

[0053] Referring to Figures 1-7In another embodiment of the present application, an atomization device is provided, which comprises an atomization assembly 10, a liquid storage cup 20, and a transfer shell 30. The atomization assembly 10 is the atomization assembly 10 in the above embodiment. The liquid storage cup 20 has a liquid storage cavity 26 for storing liquid to be atomized. One end of the liquid storage cup 20 is a suction nozzle 21, and the other end is a mounting opening 22. The transfer shell 30 is sleeved in the liquid storage cup 20 through the mounting opening 22. The atomization assembly 10 is arranged in the transfer shell 30, and the second support 132 is located on the side facing the suction nozzle 21. The atomization device has an activated state and an inactivated state. In the activated state, the liquid storage cavity 26 and the outer liquid guide 12 are in communication. In the inactivated state, the liquid storage cavity 26 and the outer liquid guide 12 are isolated. Two first buckle positions 23 are arranged on the side wall of the liquid storage cup 20 in an axial direction. The outer side wall of the transfer shell 30 is provided with a first buckle part 31. The first buckle part 31 is used for buckling connection with the first buckle positions 23 in different positions, so as to switch different states of the atomization device. The same axial position of the liquid storage cup 20 can be provided with a plurality of first buckle positions 23 (for example, two first buckle positions 23). Correspondingly, the same axial position of the outer side wall of the transfer shell 30 is provided with a plurality of first buckle parts 31 (for example, two first buckle parts 31). The plurality of first buckle positions 23 and the plurality of first buckle parts 31 correspond to each other, so as to ensure the connection strength or stability of the liquid storage cup 20 and the transfer shell 30.

[0054] The designed atomization device can better guarantee the use effect of the atomization device through the activated state and the inactivated state. For example, when the atomization device is not used for a long time, the atomization device can be placed in the inactivated state through the cooperation of the liquid storage cup 20 and the transfer shell 30, so as to avoid the contact between the liquid to be atomized and the outer liquid guide 12, thereby causing unnecessary volatilization and gasification waste, or better guaranteeing the edible taste of the liquid to be atomized. When the atomization device is used, the first buckle part 31 and the first buckle position 23 at the corresponding position are buckled and connected, and the atomization device is placed in the activated state. At the same time, since the pre-liquid injection operation is performed on the atomization assembly 10 in the atomization device, the user can quickly use the atomization device without waiting for the process of transferring the liquid to be atomized to the inner liquid guide 11, and the use of the atomization device is more convenient.

[0055] Please refer to Figures 5-7 The end of the transfer shell 30 away from the suction nozzle 21 is provided with a first stop part 32, which is used for abutting against the mounting opening 22. The first stop part 32 is, for example, a radially protruding block or ring on the outer side wall of the transfer shell 30. Through the abutment of the first stop part 32 and the mounting opening 22, the relative position between the liquid storage cup 20 and the transfer shell 30 is limited, so as to avoid the phenomenon of excessive operation. For example, as Figure 5As shown, the atomizer is in an inactive state at this time, and the first buckle portion 31 is buckled with the first buckle position 23 below the liquid storage cup 20. When the atomizer needs to be in an active state, the intermediate shell 30 is pushed upward, and the first buckle portion 31 is buckled with the first buckle position 23 above the liquid storage cup 20, becoming Figure 6 In the structure shown, the first stopper 32 is now in contact with the mounting opening 22 , and the intermediate housing 30 does not need to be pushed further.

[0056] See also Figures 5-7 , the atomizing device also includes a fixing seat 40 and a sealing sleeve 50. The liquid storage cup 20 includes an inner tube 24 and an outer tube 25, and the inner tube 24 and the outer tube 25 enclose a liquid storage chamber 26. The fixing seat 40 is fixed in the intermediate shell 30, and a liquid inlet hole 41 is provided on the side wall of the fixing seat 40. In the activated state, the top of the intermediate shell 30 and the sealing sleeve 50 are spaced apart, and the liquid storage chamber 26 is connected to the outer layer liquid guide member 12 through the liquid inlet hole 41. In the unactivated state, the top inner diameter of the intermediate shell 30 and the outer wall of the sealing sleeve 50 are tightly matched to isolate the liquid storage chamber 26 and the liquid inlet hole 41. The atomizing assembly 10 is fixed in the fixing seat 40, and part of the second bracket 132 is sleeved in the inner tube 24. One end of the sealing sleeve 50 is sleeved with the inner tube 24, and the other end is sleeved with the fixing seat 40.

[0057] To ensure the atomizer's tightness, a sealing ring is installed between the intermediate housing 30 and the outer tube 25 of the liquid storage cup 20. The sealing ring is always located between the first snap-fit ​​position 23 and the mouthpiece 21. A sealing ring is also installed between the fixing base 40 and the intermediate housing 30. The fixing base 40 is tightly fitted with the sealing ring and the inner wall of the intermediate housing 30. The liquid inlet 41 is located between the fixing base 40 and the intermediate housing 30, and the sealing ring faces the mouthpiece 21.

[0058] See also Figures 5-7 The atomizing device further includes a liquid absorbing member 60. A mounting groove 42 is defined at one end of the fixing base 40 away from the atomizing assembly 10. The liquid absorbing member 60 is disposed within the mounting groove 42 and communicates with the inner liquid guide member 11. The liquid absorbing member 60 is configured to absorb liquid to be atomized that leaks from the inner liquid guide member 11. The liquid absorbing member 60 is also an annular columnar shape. The inner diameter of the liquid absorbing member 60 is smaller than that of the inner liquid guide member 11, so as to facilitate absorption of liquid to be atomized that leaks from the inner liquid guide member 11. The liquid absorbing member 60 may be, for example, a liquid absorbent cotton.

[0059] See also Figure 1Correspondingly, the fixing base 40 is provided with a corresponding hole position, and the inner layer liquid guide 11 and the liquid suction member 60 are communicated. The fixing base 40 is provided with a mounting chamber on the side facing the atomization assembly 10, and the mounting chamber and the fixing base 40 are provided with a support pipe 43 at the corresponding position of the hole position. The outer diameter of the outer layer liquid guide 12 is matched with the radial dimension of the mounting chamber, and the outer layer liquid guide 12 and the support pipe 43 are sleeved, for example, the outer layer liquid guide 12 is sleeved on the outer side of the support pipe 43, and the inner layer liquid guide 11 and the support pipe 43 are in abutment or axially spaced apart. The outer wall of the fixing base 40 is provided with a second stop portion 44, and the second stop portion 44 abuts against the sealing sleeve 50, so as to limit the sealing sleeve 50.

[0060] Please refer to Figures 5-7 The atomization device further comprises a base 70, the base 70 is connected with the fixing base 40, and the liquid suction member 60 is fixed between the base 70 and the fixing base 40. The base 70 is provided with a hollow chamber on the side facing the fixing base 40, and part of the fixing base 40 is arranged in the hollow chamber.
