[0048] Figure 1Some preferred embodiments of the electronic atomization device of the present invention are shown. The electronic atomization device can be used to heat a liquid matrix to atomize it to produce an aerosol for users to inhale. The electronic atomization device has the advantages of good liquid matrix preservation effect, low leakage, high consumer experience, and high liquid matrix utilization rate.

[0049] like Figures 1 to 3 As shown, in some embodiments, the electronic atomization device includes a nozzle assembly 10 and an atomization assembly 20. The nozzle assembly 10 is assembled with the atomization assembly 20 and can be relatively rotatably arranged with the atomization assembly 20. The nozzle assembly 10 can be used for the user to inhale the aerosol, and can also be used to store the liquid matrix. The atomization assembly 20 can be used to atomize the liquid matrix in the nozzle assembly 10 to generate an aerosol, and the aerosol is output through the nozzle assembly 10.

[0050] like Figures 4 to 10 As shown, in some embodiments, the nozzle assembly 10 includes a first shell 11, a cover plate 12 and a seal 13. The first shell 11 can be used to form a nozzle, and the inner part of the space can be used to accommodate the liquid matrix, and the inner part of the space can be used to assemble with the atomization assembly 20. The cover plate 12 and the seal 13 are accommodated in the first shell 11, approximately located in the middle of the first shell 11, and are both connected and fixed to the first shell 11.

[0051] The first housing 11 includes a body 111 and an airway tube 112. The body 111 is generally a cylindrical structure with a hollow inner side. The body 111 has a first end 111a and a second end 111b in its axial direction, and the first end 111a is provided with a socket 1110, and the body 111 can be sleeved on a part of the atomization assembly 20 through the socket 1110. The second end 111b of the body 111 can be flatly arranged to form a nozzle structure for the user to inhale aerosol. The inner side wall of the body 111 is provided with a step 1111, which is arranged along the circumference of the body 111 and is located in the middle of the body 111, and is used to limit the installation of the cover plate 12. The airway tube 112 is arranged at the central axis of the body 111, one end is connected to the second end 111b, and the other end is arranged toward the socket 1110. The length of the airway tube 112 is less than the height of the body 111 in the axial direction. The airway tube 112 is a through structure at both ends, and the port connected to the second end 111b forms a suction port 1121 to output aerosol for the user to inhale. An air outlet channel 1122 may be formed inside the airway tube 112. The outer wall of the airway tube 112 is spaced apart from the inner wall of the body 111.

[0052] A liquid storage chamber 113 is formed in the first shell 11. Specifically, the liquid storage chamber 113 can be formed by the interval between the airway tube 112 and the body 111, and is used to store liquid matrix to supply to the atomizer assembly 20. In some embodiments, there are at least two liquid storage chambers 113, and at least two liquid storage chambers 113 are arranged in sequence along the circumference of the first shell 11. Each liquid storage chamber 113 can be arranged in equal volume. Specifically, the liquid storage chamber 113 can be two in some embodiments, that is, including a first liquid storage chamber 113a and a second liquid storage chamber 113b. In some other embodiments, the liquid storage chamber 113 is not limited to two, and can be three, four or five, etc. In some other embodiments, the volume of each liquid storage chamber 113 can also be set differently.

[0053] In some embodiments, one or more of the at least two liquid storage chambers 113 can be selected to be connected to the heating structure 231 of the atomizer assembly 20 to supply liquid to the heating structure 231. At least two liquid storage chambers 113 are also configured so that the number of liquid storage chambers connected to the heating structure 231 is less than the total number of liquid storage chambers 113, and when one or more of the liquid storage chambers 113 are connected to the heating structure 231, the remaining liquid storage chambers 113 are separated from the heating structure 231 and are in a closed state, thereby preserving the liquid matrix in some of the liquid storage chambers 113, reducing the amount of liquid leakage, improving the consumer experience, and improving the utilization rate of the liquid matrix. It should be noted that multiple can refer to more than two (including two). In some embodiments, when there are two liquid storage chambers 113, one of the liquid storage chambers 113 can be selected to be connected to the heating structure 231, and the other liquid storage chamber 113 can be selected to be in a closed state with the heating structure 231, that is, the first liquid storage chamber 113a can be connected to the heating structure 231, and the second liquid storage chamber 113b can be in a closed state, so as to preserve the liquid matrix in the second liquid storage chamber 113b. The two liquid storage chambers 113 are switchable. When the liquid matrix in the first liquid storage chamber 113a is consumed, it can be switched to the second liquid storage chamber 113b to be connected to the heating structure 231. When there are more than two liquid storage chambers 113, such as three, one or two of them can be selected to be connected to the heating structure 231, and the remaining liquid storage chambers 113 can be separated from the heating structure 231 and in a closed state, and the three liquid storage chambers 113 can be switched. The switching of the liquid storage chamber 113 can be achieved by rotating the nozzle assembly 10 or the atomization assembly 20.

[0054] Since the liquid storage tank with a large liquid injection volume is divided into at least two liquid storage chambers 113 with small liquid injection volumes, one or more of them (less than the total number of liquid storage chambers 113) are used separately. Since the volume of the liquid storage chamber 113 is small, the liquid storage chamber 113 is ventilated and the air classroom entering the liquid storage chamber 113, when the ambient temperature rises, the internal air volume expands less, and then the amount of liquid matrix squeezed out of the liquid storage chamber 113 is less, and less liquid matrix can be stored in the atomization component 20, thereby reducing the risk of leakage of the liquid storage chamber 113, and the remaining liquid storage chambers 113 are in a completely closed state, so they will not be affected by changes in ambient temperature and will not leak.

[0055] In some embodiments, each liquid storage chamber 113 has an opening 1130, which is disposed toward the atomizer assembly 20, that is, toward the heating structure 231. The opening 1130 is defined by the step 1111, that is, the opening 1130 is located on the plane where the end surface of the step 1111 disposed toward the socket 1110 is located. The opening 1130 can be assembled on the cover plate 12.

[0056] In some embodiments, at least two retaining ribs 114 may be disposed inside the first shell 11, and at least two retaining ribs 114 may be disposed at intervals along the outer periphery of the airway tube 112, one side of which is tightly connected to the outer wall of the airway tube 112, and the other side of which is tightly connected to the inner wall of the body 111, thereby separating the space between the end of the airway tube 112 away from the suction port 1121 and the second end 111b in the first shell 11 into at least two independent liquid storage chambers 113. In some embodiments, the retaining ribs 114, the airway tube 112, and the body 111 may be integrally formed.

[0057] In some embodiments, the inner wall of the first shell 11 is further provided with ribs 115 for connecting and fixing the cover plate 12 and the seal 13. There are multiple ribs 115, and the multiple ribs 115 are arranged at intervals along the circumference of the first shell 11, and each rib 115 can be arranged along the axial longitudinal length of the first shell 11. The length of each rib 115 is less than the height of the first shell 11, and its length can be roughly equivalent to the length of the airway tube 112, specifically, it can be slightly less than the length of the airway tube 112. By providing the ribs 115 to connect the cover plate 12 and the seal 13, when the user rotates the first shell 11, the cover plate 12 and the seal 13 can be driven to rotate together, thereby ensuring the independence and reliability of the liquid storage chamber 113 during rotation.

[0058] The cover plate 12 is installed at the opening 1130 of the liquid storage chamber 113. In some embodiments, there may be two cover plates 12, which are arranged one-to-one with the liquid storage chamber 113, that is, the cover plate 12 may include a first cover plate 12a and a second cover plate 12b, the first cover plate 12a is located at the opening 1130 of the first liquid storage chamber 113a, and the second cover plate 12b is located at the opening 1130 of the second liquid storage chamber 113b. In some embodiments, the cover plate 12 may be one, three, four or more than four. The cover plate 12 may be connected and fixed to the first shell 11, specifically, the cover plate 12 and the first shell 11 may be fixed by snapping. In some other embodiments, the cover plate 12 and the first shell 11 are not limited to being connected and fixed by snapping, and may also be fixed to the first shell 11 by interference fit.

[0059] In some embodiments, the cover plate 12 includes a covering portion 121, and the shape and size of the covering portion 121 can be adapted to the shape and size of the opening 1130. At least one first liquid inlet 122 is provided on each cover plate 12, and the number of the first liquid inlet 122 is provided corresponding to the number of the liquid storage chambers 113, that is, the total number of the first liquid inlet 122 can be at least two. In some embodiments, when there are at least two cover plates 12, there is one first liquid inlet 122 on each cover plate 12, that is, there are at least two first liquid inlets 122. In some other embodiments, when there is one cover plate 12, there are two or more first liquid inlets 122, such as when there are two liquid storage chambers 113, there can be two first liquid inlets 122 on the cover plate 12. The first liquid inlet 122 is located on the covering portion 121. Each first liquid inlet 122 is connected to the corresponding liquid storage chamber 113. For example, the first liquid inlet 122 on the first cover plate 12a is connected to the first liquid storage chamber 113a.

[0060] In some embodiments, the outer wall of the cover plate 12 is provided with a first snap-in socket 123, and the first snap-in socket 123 can be provided one-to-one with the rib 115. When the cover plate 12 is assembled with the first shell 11, the cover plate 12 can be pushed into the first shell 11 and placed at the step 1111. The rib 115 can be inserted one-to-one into the first snap-in socket 123 to achieve connection and fixation.

[0061] In some embodiments, the cover plate 12 is provided with a notch 124 for assembling with the airway tube 112. The notch 124 has a semicircular cross section and is centrally arranged on the side of the cover portion 121 facing the other cover plate 12. When the two cover plates 12 are assembled, the notches 124 of the two cover plates 12 are arranged opposite to each other and surround a substantially cylindrical plug-in through hole for partially inserting the airway tube 112. When there is only one cover plate 12, the notch 124 is located at the central axis of the cover portion 121 and is substantially cylindrical.

[0062] In some embodiments, a first groove 125 is formed on the cover plate 12. Specifically, in some embodiments, when there are at least two cover plates 12, two adjacent cover plates 12 may be spaced apart, and when the cover plates 12 are both assembled in the corresponding liquid storage chambers 113, the space between the two adjacent cover plates 12 is formed in the first groove 125 into which the retaining rib 114 is inserted. When there is only one cover plate 12, a first groove 125 corresponding to the retaining rib 114 may be provided on the end surface of the covering portion 121 of the cover plate 12.

[0063] In some embodiments, a guide structure 126 is provided on the cover plate 12, and the guide structure 126 can be located on the edge of the first groove 125 and protrude from the covering portion 121. The guide structure 126 can be provided on both opposite sides of the first groove 125, and the guide structures 126 on the two opposite sides of the first groove 125 are provided one by one. The guide structure 126 can be roughly wedge-shaped or trapezoidal. In some embodiments, the guide structure 126 has a guide slope 1261, and the guide slope 1261 is inclined toward the first groove 125. The guide slopes 1261 of the two relatively arranged guide structures 126 are arranged relatively to each other and form an inverted figure eight structure. By providing the guide structure 126, the retaining rib 114 can be introduced into the first groove 125, thereby realizing the guided installation of the cover plate 12 and the first shell 11, preventing assembly dislocation during production, and improving production efficiency.

[0064] In some embodiments, the seal 13 has an end face 13a and an annular side wall 3b, the end face 13a is arranged opposite to the cover plate 12, and the annular side wall 3b is connected to the end face 13a. In some embodiments, the seal 13 is provided with a liquid inlet hole 131, and the liquid inlet hole 131 can be opened on the end face 13a, which can be arranged in a one-to-one correspondence with the first liquid inlet port 122 and connected accordingly. In some embodiments, the number of liquid inlet holes 131 on the seal 13 is set corresponding to the number of the first liquid inlet port 122. In some embodiments, there can be at least two liquid inlet holes 131 on the seal 13, specifically, there can be two liquid inlet holes 131 on the seal 13. In some other embodiments, there can also be three, four, etc. liquid inlet holes 131 on the seal 13. In some embodiments, a central through hole 132 is provided on the seal 13. The central through hole 132 is located at the central axis of the end surface 13a. The central through hole 132 can be coaxially arranged with the plug-in through hole on the cover plate 12 and correspondingly connected to be used for partial insertion of the airway tube 112.

[0065] In some embodiments, the cover plate 12 and the seal 13 can be fixed by snapping and / or interference fit. Specifically, in some embodiments, the cover plate 12 and the seal 13 can be fixed by setting a snap-fit ​​structure, so that the pulling and wrinkling of the seal 13 glue after being stressed can be reduced during the rotation process, allowing the nozzle assembly 10 to rotate more smoothly. The side where the cover plate 12 and the end surface 13a of the seal 13 are arranged opposite to each other has a contact surface 120. The snap-fit ​​structure can be arranged on the contact surface 120 and the end surface 13a. In some embodiments, the snap-fit ​​structure may include a card table 133 and a card slot 127. In some embodiments, the card table 133 may be located on the end surface 13a. The card slot 127 may be opened on the contact surface 120. Each card table 133 is arranged in a one-to-one correspondence with a card slot 127. In some embodiments, the card table 133 may include a first card table 133a and a second card table 133b. There may be a plurality of first decks 133a, and the plurality of first decks 133a are arranged near the edge of the end face 13a and protrude from the end face 13a. The plurality of first decks 133a may be arranged at intervals along the circumference of the end face 13a. The second deck 133b is located on the inner side of the first deck 133a, and the plurality of second decks 133b may be arranged at intervals along the circumference of the central through hole 132. Correspondingly, the card slot 127 may include a first card slot 127a and a second card slot 127b. The first card slot 127a is arranged in a one-to-one correspondence with the first deck 133a. The second card slot 127 is arranged in a one-to-one correspondence with the second deck 133b. When the cover plate 12 and the seal 13 are assembled, the first deck 133a may be inserted into the first card slot 127a, and the second deck 133b may be inserted into the second card slot 127b.

[0066] In some embodiments, the seal 13 further includes a positioning structure 134, which is protrudingly arranged on the end surface 13a. In some embodiments, the positioning structure 134 can be used to cooperate with the cover plate 12 for positioning. In some embodiments, the positioning structure 134 can be located on the second card platform 133b, which can be columnar and can extend in the direction where the cover plate 12 is provided. The positioning structure 134 can pass through the cover plate 12 and be fixed to the cover plate 12. It can fix the position of the cover plate 12 on the seal 13 and prevent the cover plate 12 from separating from the seal 13. In some embodiments, the cover plate 12 is provided with a through hole 128 for the positioning structure 134 to pass through, and the through hole 128 is arranged one-to-one with the positioning structure 134. The outer periphery of the positioning structure 134 is provided with a positioning convex rib 1341, which can be arranged along the outer peripheral wall of the positioning structure 134, and can be annular, and its outer diameter is slightly larger than the outer diameter of the through hole 128. When the positioning structure 134 passes through the through hole 128, the positioning rib 1341 can be brought to the end of the through hole 128 facing the liquid storage chamber 113 under the action of elasticity and abut against the cover plate 12, thereby fixing the cover plate 12 to prevent the cover plate 12 from falling during assembly, thereby improving production efficiency.

[0067] In some embodiments, the seal 13 and the first shell 11 can be snap-fitted and interference fit. Of course, in some other embodiments, the seal 13 can only be snap-fitted with the first shell 11 or only have an interference fit with the first shell 11. In some embodiments, a second bayonet 135 is provided on the annular side wall 13b of the seal 13, and the second bayonet 135 is arranged one-to-one with the first bayonet 123 and is correspondingly connected. The rib 115 can be snapped into the second bayonet 135 along the first bayonet 123, so as to realize the snap-fit ​​of the seal 13 and the first shell 11. In some embodiments, a sealing rib 136 can be provided on the annular side wall 13b of the seal 13, and the sealing rib 136 is tightly against the inner wall of the first shell 11, so that the seal 13 and the first shell 11 can have an interference fit.

[0068] In some embodiments, the cover plate 12 is a hard structure, and the seal 13 is an elastic structure. After the cover plate 12 is subjected to force, it is pressed onto the seal 13, and its entire contact surface 120 can be pressed onto the end surface 13a of the seal 13, so that the seal 13 can be subjected to uniform force and the sealing performance is more reliable.

[0069] like Figures 11 to 16 As shown, in some embodiments, the atomizer assembly 20 may include a second shell 21, a bracket 22, a heating assembly 23, an atomizer seat 24, and a power supply 25. The second shell 21 is sleeved on the outer periphery of the bracket 22. The bracket 22 is used to accommodate the heating assembly 23, the atomizer seat 24 and the power supply 25. The heating assembly 23 includes a heating structure 231 and a conductive structure 232. The heating structure 231 can heat the liquid matrix to produce an aerosol when powered on. The conductive structure 232 can be connected to the heating structure 231. In some embodiments, the conductive structure 232 can be a thimble.

The start switch 26 can be turned on or off by detecting whether negative pressure is generated in the start airway 273.

[0082] In some embodiments, the atomizer assembly 20 further includes an air inlet channel 22c, which is in communication with the outside and the atomizing chamber 220, and is used to allow external gas to enter the atomizing chamber 220. Specifically, an air inlet groove 226 in communication with the outside is provided on the receiving portion 22b of the bracket 22, an air inlet hole 227 is provided on the end wall of the receiving portion 22b disposed toward the supporting portion 22a, an annular groove 228 is provided between the receiving portion 22b and the supporting portion 22a, and a through groove 229 extending in the radial direction of the bracket 22 is provided between the supporting portion 22a and the receiving portion 22b, and the air inlet groove 226, the air inlet hole 227, the annular groove 228 and the through groove 229 are sequentially connected to form the air inlet channel 22c.

[0084] In some embodiments, the boss 272 of the sealing structure 27 can be inserted into the air inlet channel 22c, thereby preventing the leaked liquid in the air inlet channel 22c from flowing into the start switch 26 and causing the start switch 26 to fail. Specifically, the boss 272 can be located between the first channel section 2201 and the second channel section 2202, so that the start air channel 273 can be located between the first channel section 2201 and the second channel section 2202, that is, located in the third channel section 2203, and then can be misaligned with the air guide column 222, thereby preventing the liquid matrix in the atomization chamber 220 from leaking out and entering the start switch 26 from the start air channel 273, affecting the start.

[0085] In some embodiments, the atomization assembly 20 further includes a liquid absorption structure 28, which can be installed in the third channel section 2203. There are two liquid absorption structures 28, and the two liquid absorption structures 28 can be respectively located on two opposite sides of the boss 272.

The leaked liquid can be a liquid matrix leaked from the liquid storage chamber 113 to the air inlet channel 22c, or it can be a condensed liquid leaked to the air inlet channel 22c after the aerosol formed by the atomization of the liquid matrix is ​​condensed. In some embodiments, the liquid absorption structure 28 can be selected as a liquid absorbent cotton.

[0086] In some embodiments, the atomizer assembly 20 further includes a sealing ring 29, which is sleeved on the bracket 22 and located on the side of the third channel section 2203 away from the atomization chamber 220, and is in close contact with the inner wall of the second housing 21, so that the space of the third channel section 2203 is relatively sealed, which is conducive to the generation of negative pressure at the start airway 273 during suction, thereby ensuring the sensitivity of the start switch 26. In some embodiments, the sealing ring 29 can be selected as an O-ring.
