[0026] This application provides an electronic atomization device 100, please refer to Figure 1-5 The electronic atomization device 100 includes a first shell 110 , an atomizer 120 , a liquid storage container 130 and a power supply assembly 140 .

[0027] Please refer to Figure 2-3 The first shell 110 includes a suction nozzle 111, a first disassembly port 112 and a second disassembly port 113. The first disassembly port 112 and the suction nozzle 111 are arranged side by side at the first end of the first shell 110, and the second disassembly port 113 is arranged at the second end of the first shell 110 opposite to the first end. The interior of the first shell 110 is hollow, forming a receiving space 114 that is connected to the first disassembly port 112 and the second disassembly port 113 respectively. The atomizer 120 can be detachably installed in the receiving space 114 from the second disassembly port 113, docked with the suction nozzle 111, and limited by the suction nozzle 111. The liquid storage container 130 can be detachably installed in the receiving space 114 from the first disassembly port 112, and docked with the atomizer 120 to supply atomized liquid to the atomizer 120. The power supply assembly 140 can be detachably installed in the receiving space 114 from the second disassembly port 113, and is electrically connected to the atomizer 120.

[0028] The electronic atomizer device 100 of the present application is provided with a first disassembly opening 112 and a second disassembly opening 113 at opposite ends of a first housing 110. The interior of the first housing 110 is hollow, forming a receiving space 114 that communicates with the first disassembly opening 112 and the second disassembly opening 113. The liquid storage container 130 and the power supply assembly 140 can be removed and installed through the first disassembly opening 112 and the second disassembly opening 113, thereby improving the assembly efficiency of the electronic atomizer device 100.

[0029] Please refer to Figure 2 Atomizer 120 includes an oil cup 121. Oil cup 121 defines a first mounting cavity 1211 and an atomizing cavity 1212. Atomizing cavity 1212 communicates with nozzle 111. First mounting cavity 1211 faces first disassembly opening 112. Liquid storage container 130 is removably mounted in first mounting cavity 1211 via first disassembly opening 112. Oil cup 121 is removably mounted in first housing 110 via second disassembly opening 113. Oil cup 121 is positioned away from second disassembly opening 113 relative to power supply assembly 140.

[0030] By disposing the oil cup 121 in the first housing 110 , other parts of the atomizer 120 can be integrated and installed in the oil cup 121 first, and then the oil cup 121 is installed in the first housing 110 , which can make the assembly of the atomizer 120 simpler and faster.

[0031] In the examples of this application, please refer to Figure 2 and Figure 6 The oil cup 121 has a partition side wall 1213, and the first installation cavity 1211 and the atomization cavity 1212 are separated by the partition side wall 1213. The side of the partition side wall 1213 that is in contact with the liquid storage container 130 has a first protrusion structure, and the side of the liquid storage container 130 that is in contact with the partition side wall 1213 has a first groove. The first protrusion structure is inserted into the first groove structure, further fixing the liquid storage container 130 to the first installation cavity 1211.

[0032] Please refer to Figure 6 The atomizing chamber 1212 includes an airway 1214 and an atomizing space 1215. The airway 1214 is connected to the suction nozzle 111, and the atomizing space 1215 is connected to the end of the airway 1214 away from the suction nozzle 111. Figure 3 The atomizer 120 includes an atomizing core 124 disposed in the atomizing space 1215 and a liquid storage chamber 161 respectively communicating with the atomizing space 1215 and the liquid storage container 130 .

[0033] By separately configuring the atomization chamber 1212 as the airway 1214 and the atomization space 1215 , the aerosol atomized by the atomization core 124 can be transmitted to the mouthpiece 111 through the airway 1214 .

[0034] Please refer to Figure 2-3The liquid storage container 130 is inverted from the first disassembly opening 112 into the first installation cavity 1211, that is, the container cover 131 of the liquid storage container 130 is arranged on the side away from the first disassembly opening 112, and the bottom of the liquid storage container 130 covers the first disassembly opening 112. The container cover 131 is provided with an atomized liquid flow outlet 1311 and a limiting member 132, and the limiting member 132 is arranged to enclose the atomized liquid flow outlet 1311. The liquid storage container 130 also includes a first sealing member 133, and the limiting member 132 is used to limit the first sealing member 133 to prevent the first sealing member 133 from completely separating from the container cover 131. Please refer to Figure 2 The limiting member 132 has a connecting end and a limiting end. One side of the connecting end is connected to the container cover 131, and the other side is connected to the limiting end. The limiting end has a limiting hole, and the limiting hole is arranged opposite to the atomized liquid flow outlet 1311. The first sealing member 133 includes a sealing plug 1331, a sealing rod 1332, and a spring 1333. One end of the sealing rod 1332 is connected to the sealing plug 1331, and the other end passes through the limiting hole. The sealing rod 1332 has a limiting protrusion around the circumference of the end passing through the limiting hole. The radial dimension of the limiting protrusion is larger than the limiting hole, preventing the sealing rod 1332 from escaping from the limiting hole, thereby preventing the first sealing member 1333 from escaping from the container cover 131 from the side of the atomized liquid flow outlet 1311 away from the limiting member 132. The spring 1333 is sleeved on the side of the sealing rod 1332. One end of the spring 1333 abuts the sealing plug 1331, and the other end abuts the limiting end, so that the sealing plug 1331 is elastically set on the atomized liquid flow outlet 1311, which is convenient for opening or closing the atomized liquid flow outlet 1311.

[0035] Also, please refer to Figure 3 The atomizer 120 includes a liquid guide tube 122, a liquid storage component 123, an atomizing core 124, and an atomizing tube 125. One end of the liquid guide tube 122 is connected to the atomized liquid outlet 1311, and the other end extends into the atomizing space 1215. The atomizing core 124 is arranged in the atomizing space 1215 and communicates with the airway 1214. The liquid storage component 123 encloses the liquid guide tube 122 and the atomizing tube 125, thereby guiding the atomized liquid flowing out of the liquid storage container 130 to the atomizing core 124 for atomization. A ejector pin 1221 is provided in the liquid guide tube 122, and the ejector pin 1221 is used to resist the sealing plug 1331, thereby opening the atomized liquid outlet 1311. When the liquid storage container 130 is removed from the first disassembly port 112, the sealing plug 1331 can plug the atomized liquid outlet 1311 again under the restoring force of the spring 1333.

[0036] Please refer to Figure 2-3The electronic atomization device 100 further includes a second sealing member 150, which is located between the nozzle 111 and the sidewall of the airway 1214, thereby creating an interference fit between the nozzle 111 and the airway 1214. Furthermore, the second sealing member 150 is located between the first housing 110 at the first disassembly opening 112 and the outer wall of the first installation cavity 1211, thereby sealing the first installation cavity 1211.

[0037] The second sealing member 150 can seal the nozzle 111 and the airway 1214 to prevent leakage of the atomized aerosol.

[0038] Please refer to Figure 3 The atomizer 120 further includes an air guide tube 126 and a first liquid absorbing member 127. One end of the air guide tube 126 is in communication with the atomizing core 124, and the other end extends toward the mouthpiece 111 and is located outside the atomizing space 1215. The interior of the air guide tube 126 defines at least a portion of an air passage 1214. The first liquid absorbing member 127 is disposed outside the atomizing space 1215 and surrounds the air guide tube 126, defining a portion of the air passage 1214. In other words, a gap exists between the air guide tube 126 and the mouthpiece 111, and the first liquid absorbing member 127 is at least partially located within this gap, thereby absorbing more condensed liquid.

[0039] Please refer to Figure 3 The electronic atomization device 100 includes a bracket 160, and the oil cup 121 includes an oil cup bottom 1217. The bracket 160 and the oil cup 121 define a liquid storage chamber 161, and the liquid storage member 123 is disposed in the liquid storage chamber 161. A liquid leakage buffer space 170 is defined between the oil cup bottom 1217 and the bracket 160. The liquid leakage buffer space 170 is provided with a second liquid absorbent member 171 for absorbing leaked liquid and condensed liquid.

[0040] Please refer to Figure 3 The air passage 1214 and the first installation cavity 1211 are arranged side by side, and the liquid storage cavity 161 is arranged on a side of the atomization cavity 1212 and the first installation cavity 1211 away from the first end of the first shell 110 .

[0041] The air passage 1214 and the first installation cavity 1211 are arranged side by side. When the overall volume of the electronic atomization device 100 remains unchanged, the liquid storage capacity of the liquid storage container 130 can be expanded because the volume occupied by the air passage 1214 is smaller.

[0042] Please refer to Figure 3 The first shell 110 includes a rib 115 protruding from the inner edge of the first disassembly opening 112 . The rib 115 and the suction nozzle 111 jointly restrict the oil cup 121 to prevent the oil cup 121 from sliding out from the side away from the second disassembly opening 113 .

[0043] Please refer to Figure 3A lifting portion 134 is provided on the outer edge of the bottom wall of the liquid storage container 130, and an avoidance space 116 is provided at a position corresponding to the lifting portion 134 of the first shell 110. The avoidance space 116 facilitates the operator to lift the lifting portion 134 and then disassemble the liquid storage container 130.

[0044] Please refer to Figure 2-3 The electronic atomization device 100 also includes a second housing 180, which is installed in the first housing 110 through the second disassembly opening 113. The oil cup 121 is disposed in the second housing 180. A first abutting portion 1216 is provided on the outer periphery of the oil cup 121 near the first end of the first housing 110. The second housing 180 abuts against the side of the first abutting portion 1216 facing away from the first end. The provision of the retaining edge 115 helps to retain the oil cup 121 and prevent the second housing 180 from falling out.

[0045] By protruding a first supporting portion 1216 on the outer periphery of the oil cup 121 near the first end, the second shell 180 is supported on the side of the first supporting portion 1216 facing away from the first end. On the one hand, the oil cup 121 can be conveniently installed in a position near the first end of the first shell 110 through the second shell 180. On the other hand, the oil cup 121 can be pressed against the suction nozzle 111 by pressing the second shell 180, thereby achieving a sealed connection between the atomization chamber 1212 and the suction nozzle 111, which helps to transport the atomized aerosol to the suction nozzle 111 as much as possible.

[0046] Please refer to Figure 3 The bottom 1217 of the oil cup and the sidewall of the second housing 180 enclose a second mounting cavity 190. The electronic atomization device 100 also includes a circuit board 200. The power supply assembly 140 and the circuit board 200 are disposed in the second mounting cavity 190, and the circuit board 200 is snapped onto the bottom of the oil cup 121.

[0047] On the one hand, before installing the oil cup 121 in the first housing 110, the circuit board 200 can be first installed at the bottom of the oil cup 121 and then installed together with the oil cup 121 in the second housing 180, which facilitates the fixing of the position of the circuit board 200. On the other hand, snapping the circuit board 200 to the bottom of the oil cup 121 can facilitate the electrical connection between the circuit board 200 and the power supply assembly 140. In addition, the circuit board 200 is integrated with elastic electrode posts. The positive and negative poles of the battery 142 are both located at one end near the circuit board 200. The positive and negative poles of the battery 142 are respectively removably electrically connected to the two electrode posts on the circuit board 200.

[0048] Please refer to Figure 3-5 The electronic atomization device 100 further includes a bottom cover assembly 210 and a battery cover 220. The bottom cover assembly 210 covers the second disassembly opening 113 and abuts against the second shell 180 to prevent the second shell 180 from falling out of the second disassembly opening 113. Figure 2 The bottom cover assembly 210 is provided with a battery 142 loading port 211 , the power supply assembly 140 is loaded into the accommodating space 114 from the battery loading port 211 , and the battery cover 220 is detachably mounted on the battery loading port 211 to prevent the battery 142 from falling out of the battery loading port 211 .

[0049] The bottom cover assembly 210 abuts the second housing 180, which, on the one hand, helps to seal the oil cup 121 against the suction nozzle 111 by pressing against the second housing 180. On the other hand, it prevents the second housing 180 from escaping from the second removal opening 113. The battery cover 220 seals the power supply assembly 140 within the second installation cavity 190, preventing the battery 142 from escaping from the second removal opening 113.

[0050] In some embodiments, please refer to Figure 3-5 The bottom cover assembly 210 includes a supporting member 212 and a clamping member 213. Part of the supporting member 212 is inserted into the second installation cavity 190 from the second disassembly opening 113. The outer wall of the supporting member 212 is circumferentially provided with a supporting step 2121. The supporting step 2121 abuts the first shell 110 and the second shell 180, so that the second shell 180 can tightly abut the oil cup 121 against the suction nozzle 111. One end of the clamping member 213 encloses the end of the supporting member 212 away from the first disassembly opening 112, and the other end is clamped with the first shell 110. In this way, the supporting member 212 can be installed on the first shell 110. Please refer to Figure 5 The clamping member 213 is provided with a battery loading port 211, and the power supply assembly 140 can be installed into the second installation cavity 190 through the battery loading port 211. Please refer to 4, the first shell 110 is provided with a second protrusion structure 117, and the clamping member 213 is provided with a second groove 2131 at the position corresponding to the second protrusion structure 117. The second groove 2131 cooperates with the second protrusion structure 117 to clamp the bottom cover assembly 210 to the first shell 110. Please refer to Figure 5 The battery cover 220 and the end of the supporting member 212 facing away from the second disassembly opening 113 can be screwed into each other, so as to facilitate the disassembly and installation of the power supply assembly 140.

[0051] Please refer to Figure 3 The power supply assembly 140 further includes a battery compartment 141 , in which the power supply is disposed.

[0052] An embodiment of the present application further provides an assembly method of an electronic atomization device 100.
