[0025] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0026] It should be understood that the terms "front", "rear", "left", "right", "upper", "lower", "first", "second", etc. are only for the convenience of describing the technical solution of the present invention, and do not indicate that the devices or elements referred to must have special differences, and therefore cannot be understood as limitations on the present invention. It should be noted that when a piece is considered to be "connected" to another piece, it can be directly connected to the other piece or there may be a central piece at the same time. Unless otherwise defined, all technical and scientific terms used in this document have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] Figure 1 and Figure 2 An electronic atomization device 1 in some embodiments of the present invention is shown. The electronic atomization device 1 can be used for heating and atomizing liquid media such as cigarette liquid and liquid medicine, and may include a battery device 10 and an atomizer 20 detachably mounted on the battery device 10. The battery device 10 is used to power the atomizer 20 and control operations such as opening or closing the entire electronic atomization device 1. The atomizer 20 is used to accommodate liquid media, heat and atomize the liquid media, and transport mist. In some embodiments, the battery device 10 is formed with a receiving groove 11 at the top, and the atomizer 20 is detachably embedded in the receiving groove 11 and electrically connected to the battery device 10.

[0028] Read also Figures 3 to 5In some embodiments, the atomizer 20 may include a substantially square liquid storage component 21 and an atomizer component 22 detachably mounted in the liquid storage component 21. The liquid storage component 21 is mainly used to store liquid medium and deliver mist, and the atomizer component 22 is mainly used to heat and atomize the liquid medium from the liquid storage component 21. In some embodiments, the atomizer component 22 may be inserted into the liquid storage component 21 in an interference fit (i.e., an expansion fit) so that the atomizer component 22 can be easily assembled and disassembled. This is more effective in situations where the atomizer component 22 cannot be set in a cylindrical shape.

[0029] In some embodiments, the atomizer 20 may further include a liquid injection device 23 and a nozzle assembly 24. The liquid injection device 23 is embedded in the top of the liquid storage assembly 21 and communicated with the liquid storage cavity 210 to facilitate the injection of liquid into the liquid storage cavity 210. The nozzle assembly 24 is installed on the top of the liquid storage assembly 21 and communicated with the air outlet channel 213.

[0030] See also Figure 6 and Figure 7 In some embodiments, the liquid storage component 21 may include a liquid storage chamber 210, a receiving chamber 211 connected to the liquid storage chamber 210, an air inlet channel 212 connected to the lower end of the receiving chamber 211, and an air outlet channel 213 connected to the upper end of the receiving chamber 211. The liquid storage chamber 210 is used to store liquid medium. In some embodiments, the receiving chamber 211 may be columnar so that the atomization component 22 can be detachably inserted therein. The receiving chamber 211 extends vertically upward from the bottom surface of the liquid storage component 21 to the liquid storage chamber 210, and the receiving chamber 211 is connected to the liquid storage chamber 210 via a plurality of first liquid inlets 2110. The air inlet channel 212 extends downward from the air inlet 2121 at the upper part of the liquid storage component 21, and is connected to the lower part of the receiving chamber 211 at the air outlet 2122, so that the outside air first enters the liquid storage component 21 from the upper part, and then flows downward and enters the atomizing component 22 from the lower part of the receiving chamber 211. The air outlet channel 213 is arranged directly above the receiving chamber 211 to guide the mist generated by the atomizing component 22 out.

[0031] In some embodiments, the receiving chamber 211 is provided with a first sealing member 2111 and a second sealing member 2112, which can be sealing rings, which are respectively arranged on the upper and lower sides of the first liquid inlet 2110, so that the atomizing assembly 22 can be expanded and tightly fitted when it is inserted into the receiving chamber 211, and can also prevent the liquid medium from leaking when entering the atomizing assembly 22 through the first liquid inlet 2110. The air outlet 2122 of the air inlet channel 212 is located below the second sealing member 2112 to be isolated from the liquid transmission channel above.

[0032] like Figure 8 and Fig. 9 As shown, in some embodiments, the atomizer assembly 22 may include a base 221 and an atomizer core assembly 222 detachably mounted on the base 221, so that the atomizer core assembly 222 can be replaced and the base 221 can be reused. In some embodiments, the atomizer core assembly 222 is installed on the base 221 from one side of the base 221.

[0033] In some embodiments, the base 221 may include a conductive base 2211, a conductive column 2212 insulatedly inserted into the base 2211, and a fastening bracket 2213 integrally formed on the top of the base 2211. The base 2211 and the fastening bracket 2213 are used as the first electrode connector of the atomizer assembly 22 to electrically connect to one of the positive electrode and the negative electrode of the battery device 10. The conductive column 2212 is used as the second electrode connector of the atomizer assembly 22 to electrically connect to the other of the positive electrode and the negative electrode of the battery device 10. The fastening bracket 2213 is used to hold the atomizer core assembly 222 and electrically connect the atomizer core assembly 222 to the base 2211. In some embodiments, a sealing ring 2214 is provided between the base 2211 and the conductive column 2212 to achieve an insulating connection. At the same time, due to the elastic characteristics of the sealing ring 2214, the conductive column 2212 can have a certain axial displacement after being subjected to an external force, so as to facilitate the installation of the atomizer core assembly 222.

[0034] In some embodiments, the base 2211 may be disc-shaped, and has a central through hole 2211a for the sealing ring 2214 to pass through, a groove 2211b formed on the outer wall surface circumferentially and close to the bottom surface, and a receiving groove 2211c formed on the outer wall surface circumferentially and close to the top surface. The groove 2211b is used as a force application position for the user to conveniently pull the atomizer assembly 22 out of the liquid storage assembly 21 to form a hand-pulling position at the end of the atomizer assembly 22. Accordingly, a yielding portion 2113 is provided at the opening of the receiving cavity 211 of the liquid storage assembly 21 to expose the groove 2211b for user operation. The accommodating groove 2211c is used for accommodating the third sealing member 2215 therein. The third sealing member 2215 increases the expansion and tightening force between the side wall of the atomizing assembly 22 and the inner wall of the accommodating chamber 211 on one hand, and prevents liquid leakage through the gap between the side wall of the atomizing assembly 22 and the inner wall of the accommodating chamber 211 on the other hand. Here, the atomizing assembly 22 and the liquid storage assembly 21 are matched together through three seals distributed at intervals in the upper, middle and lower parts, and the stability is very good.

[0035] In some embodiments, the conductive post 2212 may include a solid columnar embedding portion 2212a located at the lower part and a cylindrical conductive portion 2212b connected to the embedding portion 2212a and protruding from the top surface of the base 2211. A plurality of air inlet holes 2212c are further provided on the side wall of the cylindrical conductive portion 2212b to connect the outside with the central through hole of the conductive portion 2212b. The top end of the cylindrical conductive portion 2212b has a head with a larger diameter, and a first guiding portion 2212d in the shape of a chamfer is further provided on the upper side edge of the head to facilitate the installation of the atomization core assembly 222 onto the base 221.

[0036] In some embodiments, the fastening bracket 2213 may be in a C shape, and the opening on one side thereof is for the atomization core assembly 222 to be inserted from one side. The fastening bracket 2213 may include a C-shaped connecting wall 2213a connected to the base 2211, a C-shaped fixing wall 2213b connected to the upper side of the connecting wall 2213a, and a planar C-shaped retaining wall 2213c connected to the upper side of the C-shaped fixing wall 2213b and horizontally turned inward. A plurality of air passing holes 2213d may further be formed on the connecting wall 2213a to facilitate smooth air flow. The retaining wall 2213c is used to position the atomization core assembly 222 axially, and a second guiding portion 2213e may further be provided on the lower surface of the end portion of the retaining wall 2213c near the opening of the fastening bracket 2213 to facilitate the atomization core assembly 222 to be latched into the fastening bracket 2213 from the side.

[0037] Again Figure 8 And Fig. 9 As shown, in some embodiments, the atomization core assembly 222 may include a conductive fixing cylinder 2221, a cylindrical liquid absorbing member 2222 disposed in the fixing cylinder 2221, a heating member 2223 disposed in the central through hole of the liquid absorbing member 2222, a liquid locking member 2224 coated around the fixing cylinder 2221 and in liquid conduction connection with the liquid absorbing member 2222, a cylindrical conductive shell 2225 coated around the liquid locking member 2224 and in electrical connection with the fixing cylinder 2221, a sealing ring 2226 installed at the lower end of the fixing cylinder 2221, and a conductive cylinder 2227 passing through the sealing ring 2226. The central through hole of the liquid absorbing member 2222 defines an atomization chamber 2222a, and the conductive cylinder 2227 is connected to the central through hole of the liquid absorbing member 2222. A third guiding portion 2227a is formed on the outer edge of the lower end of the conductive cylinder 2227 to cooperate with the first guiding portion 2212d of the conductive post 2212 to facilitate the installation of the atomization core assembly 222. In some embodiments, the cylindrical liquid absorbing member 2222 may be wound with absorbent cotton, the heating member 2223 may be a heating wire or a heating mesh, etc., and the cylindrical liquid absorbing member 2222 and the heating member 2223 together constitute the atomization core of the atomization core assembly 222.

[0038] The heating element 2223 includes two terminals, which are electrically connected to the fixed cylinder 2221 and the conductive cylinder 2227, respectively. The fixed cylinder 2221 and the conductive cylinder 2227 are electrically connected to the base 2211 and the conductive column 2212, respectively, and then electrically connected to the positive and negative electrodes of the battery device 20, respectively. Here, the fixed cylinder 2221 and the conductive cylinder 2227 constitute the third electrode connector and the fourth electrode connector of the atomization assembly 22. The liquid locking element 2224 is to prevent the liquid medium from flowing too much to the liquid absorbing element 2222, resulting in insufficient atomization.

[0039] In some embodiments, the fixed cylinder 2221 includes a liquid inlet 2221a to allow the liquid locking member 2224 to be connected to the liquid absorbing member 2222 for conducting liquid. In some embodiments, the conductive shell 2225 may include an annular flange 2225a and a plurality of liquid inlets 2225b. The flange 2225a is formed on the circumference of the outer surface of the conductive shell 2225 near the lower end, and is used to abut against the lower side of the retaining wall 2213c of the fastening bracket 2213 to achieve the longitudinal positioning of the atomizing core assembly 222. The liquid inlet 2225b connects the liquid locking member 2224 with the liquid storage chamber 210.

[0040] When assembling the atomizer assembly 22, first align the lower end of the atomizer core assembly 222 with the lateral opening of the fastening bracket 2213 of the base 221, so that the flange 2225a of the conductive shell 2225 corresponds to the second guide portion 2213e of the retaining wall 2213c of the fastening bracket 2213, and the third guide portion 2227a of the conductive tube 2227 corresponds to the first guide portion 2212d of the conductive column 2212. However, by applying lateral pressure, the conductive tube 2227 and the conductive column 2212 are slightly elastically deformed in the direction away from each other in the soft sealing ring, and the lower end of the atomizer core assembly 222 can be completely pushed into the fastening bracket 2213. At this time, the conductive tube 2227 and the conductive column 2212 are facing each other, and the flange 2225a of the conductive shell 2225 is tightly pressed by the retaining wall 2213c of the fastening bracket 2213. The assembly of the atomizer assembly 22 is completed. When the atomizer assembly 22 needs to be disassembled, a lateral outward force is applied to overcome the friction between the atomizer core assembly 222 and the base 221, and the disassembly is completed.

[0041] For example Figure 6As shown, when the atomizer assembly 22 needs to be assembled to the liquid storage assembly 21, the atomizer assembly 22 can be forcefully inserted into the receiving chamber 211 of the liquid storage assembly 21. At this time, the first seal 2111 and the second seal 2112 are respectively expanded and tightly fitted on the outer wall surface of the conductive shell 2225 of the atomizer core assembly 222d, and are located on the upper and lower sides of the liquid inlet 2225b of the conductive shell 2225, so that the liquid storage chamber 210 of the liquid storage assembly 21 is connected to the liquid inlet 2225b of the atomizer core assembly 222. The third seal 2215 is expanded and tightly fitted on the side wall of the receiving chamber 211 near the bottom opening, and is located below the air outlet of the air inlet channel 212, so that the air inlet channel 212 of the liquid storage assembly 21 is connected to the air inlet hole 2212c of the conductive column 2212. The air outlet of the atomizing chamber of the atomizing core assembly 222d is connected to the air inlet of the air outlet channel 213 of the liquid storage assembly 21, thereby forming a complete atomizer 20 ( Figure 6 The arrows in the figure show the direction of the airflow. In some embodiments, after the atomizer assembly 22 is assembled to the liquid storage assembly 21, the bottom surface of the atomizer assembly 22 and the bottom surface of the liquid storage assembly 21 are preferably flush, which is also an advantage of the present design.

[0042] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the scope covered by the claims of the present invention.
