[0044] such asFigure 1 As shown, in an embodiment, an atomizer 1000 is provided, which includes an oil cup 100, a base unit 200, and a pressure relief member 300.

[0045] Among them, the oil cup 100 is configured with a liquid storage cavity 101. The liquid storage cavity 101 can be used to accommodate an atomization matrix. In some embodiments, the atomization matrix can be e-liquids with different flavors.

[0046] The base unit 200 can be connected to one end of the oil cup 100. In the embodiment, a gas guide tube 221 is convexly provided on one side of the base unit 200 facing the liquid storage cavity 101, and the gas guide tube 221 can be communicated with the external environment.

[0047] The pressure relief member 300 is disposed in the liquid storage cavity 101, and the pressure relief member 300 can be connected to the gas guide tube 221. The pressure relief member 300 can be communicated with the external environment through the gas guide tube 221. Correspondingly, the air pressure in the pressure relief member 300 can be consistent with the atmospheric pressure.

[0048] When the atomization matrix in the liquid storage cavity 101 is full, the pressure relief member 300 is filled with gas and has a certain volume. During use, as the atomization matrix in the liquid storage cavity 101 decreases, a cavity will be formed in the liquid storage cavity 101 and filled with gas, and the pressure relief member 300 will gradually be exposed to the cavity in the liquid storage cavity 101. When the gas in the cavity expands or contracts due to other factors, the air pressure in the cavity will also increase or decrease accordingly, resulting in an imbalance between the internal pressure of the liquid storage cavity 101 and the external atmosphere, making the atomizer 1000 unable to be used normally. In this application, by changing the volume of the pressure relief member 300, the internal pressure of the liquid storage cavity 101 is dynamically adjusted to re-balance the internal pressure of the liquid storage cavity 101 with the external environment. In some embodiments, other factors may include factors such as changes in altitude where the atomizer 1000 is located, changes in the external environmental temperature, and changes in the internal environmental temperature during the use of the atomizer 1000.

[0049] In some embodiments, during the use of the atomizer 1000, a high-temperature environment is formed inside the liquid storage cavity 101, which causes the gas in the cavity to easily expand. An air pressure difference will be formed between the inner and outer sides of the pressure relief member 300, and the gas in the cavity will exert pressure on the pressure relief member 300, which can drive the pressure relief member 300 to undergo elastic deformation and contract to discharge a part of the gas in the pressure relief member 300 to the external environment. Thus, a part of the cavity volume can be released to reduce the air pressure in the cavity and make the air pressure in the cavity tend to the atmospheric pressure. Furthermore, the risk that the remaining atomization matrix in the liquid storage cavity 101 is extruded out of the liquid storage cavity 101 under the action of positive pressure and leaks can be reduced, the probability of liquid leakage of the atomizer 1000 can be reduced, and the user experience can be improved.

[0050] In some embodiments, in a low-temperature environment, when the gas in the cavity contracts, the air pressure in the cavity will also decrease and be lower than the atmospheric pressure, creating a negative pressure environment in the cavity. A pressure difference will also be formed between the inner and outer sides of the pressure relief member 300. Under the action of the pressure difference, the gas in the external environment can enter the pressure relief member 300 through the air guide tube 221, causing the pressure relief member 300 to undergo elastic deformation and expand, thereby occupying a part of the cavity volume. Thus, the gas in the cavity can be compressed, increasing the air pressure in the cavity and approaching the atmospheric pressure. Furthermore, it can ensure that the remaining atomization matrix in the liquid storage cavity 101 can be smoothly output and used.

[0051] As Figure 1 and Figure 2 shown, the base unit 200 may include a bracket 220 and a base 210. Both the base 210 and the bracket 220 are connected to the oil cup 100, and the bracket 220 is located on the side of the base 210 facing the liquid storage cavity 101. The air guide tube 221 may be formed on the side of the bracket 220 facing away from the base 210 and inserted into the liquid storage cavity 101.

[0052] In some embodiments, an air inlet hole 211 may be formed in the base 210. The air inlet hole 211 may penetrate the base 210 along the axial direction of the atomizer 1000 and communicate with the external environment. A ventilation groove 224 may be formed on the side of the bracket 220 facing the base 210. One end of the ventilation groove 224 communicates with the air guide tube 221, and the other end of the ventilation groove 224 may communicate with the air inlet hole 211. During use, the pressure relief member 300 can conduct gas transmission with the external environment through the air guide tube 221, the ventilation groove 224, and the air inlet hole 211, thereby realizing the expansion and contraction of the pressure relief member 300.

[0053] In some embodiments, the bracket 220 may include an integrated top plate 222 and side walls 223. The side walls 223 may be disposed on the side of the top plate 222 facing the base 210, and the side walls 223 may be arranged around the edge of the top plate 222 for one week. The air guide tube 221 protrudes from the side of the top plate 222 facing away from the base 210. In the embodiment, an assembly cavity 201 may be formed by the cooperation between the base 210 and the bracket 220.

[0054] In some embodiments, the base unit 200 further includes a liquid absorption assembly 230. The liquid absorption assembly 230 may be disposed in the assembly cavity 201 between the base 210 and the bracket 220. During use, the liquid absorption assembly 230 can absorb the atomization matrix entering the base unit 200, reducing the occurrence of liquid leakage problems. Among them, the liquid absorption assembly 230 may include at least one first liquid absorption member 231, at least one second liquid absorption member 232, and at least one third liquid absorption member 233.

[0055] In some embodiments, the liquid absorption assembly 230 may include two first liquid absorption members 231, two second liquid absorption members 232, and two third liquid absorption members 233. The two first liquid absorption members 231 may be stacked along the axial direction of the atomizer 1000. One of the first liquid absorption members 231 close to the base 210 may be in contact with one side of the base 210 facing the bracket 220. The two second liquid absorption members 232 may also be stacked along the axial direction of the atomizer 1000, and the two second liquid absorption members 232 are located on the side of the first liquid absorption member 231 facing the bracket 220. One of the second liquid absorption members 232 far from the base 210 may be in contact with the surface of the top plate 222 facing the base 210. The two third liquid absorption members 233 may also be stacked along the axial direction of the atomizer 1000 and are located on the side of the first liquid absorption member 231 facing the bracket 220. One of the third liquid absorption members 233 far from the base 210 may be in contact with the surface of the top plate 222 facing the base 210. In addition, the two third liquid absorption members 233 may be disposed opposite to the two second liquid absorption members 232.

[0056] In some embodiments, the number of the first liquid absorption members 231, the number of the second liquid absorption members 232, and the number of the third liquid absorption members 233 can all be set to one, three, five, etc. according to needs. Along the axial direction of the atomizer 1000, the total thickness of the second liquid absorption members 232 may be equal to the total thickness of the third liquid absorption members 233.

[0057] In some embodiments, the second liquid absorption members 232 and the third liquid absorption members 233 may be of an integral structure.

[0058] In some embodiments, the first liquid absorption members 231, the second liquid absorption members 232, and the third liquid absorption members 233 can all be made of one or a combination of oil storage materials such as cotton sheets or sponges.

[0059] As Figure 1 and Figure 2 shown, an assembly groove 2222 is configured on the side of the top plate 222 facing the liquid storage cavity 101. In some embodiments, the top plate 222 may be configured with a recessed portion 2221 recessed in the direction of the base 210, and the assembly groove 2222 may be formed on the side of the recessed portion 2221 facing away from the base 210. The second liquid absorption members 232 and the third liquid absorption members 233 may be respectively disposed on both sides of the recessed portion 2221. The surface of the recessed portion 2221 facing the base 210 may be in contact with the first liquid absorption members 231.

[0060] As Figure 2 and Figure 4As shown, in some embodiments, a first air delivery channel 2311 is formed in the first liquid absorption member 231. The first air delivery channel 2311 may penetrate the first liquid absorption member 231 along the axial direction of the atomizer 1000. The first air delivery channels 2311 on the two first liquid absorption members 231 may be coaxially arranged. Moreover, the first air delivery channel 2311 may be opposite to and communicate with the air inlet hole 211 on the base 210.

[0061] A first air passing hole 225 is further formed in the top plate 222. The first air passing hole 225 may penetrate the top plate 222 along the axial direction of the atomizer 1000. In an embodiment, the first air passing hole 225 may be formed in the recessed portion 2221 and located at the bottom of the assembly groove 2222. The first air passing hole 225 may be opposite to and communicate with the first air delivery channel 2311.

[0062] In some embodiments, the ventilation groove 224 may be formed on the side of the top plate 222 facing the base 210. And the end of the ventilation groove 224 away from the air guide tube 221 may extend to the recessed portion 2221 and communicate with the first air passing hole 225. Correspondingly, the pressure relief member 300 may communicate with the external environment through the air guide tube 221, the ventilation groove 224, the first air passing hole 225, the first air delivery channel 2311, and the air inlet hole 211 in sequence.

[0063] As Figure 2 and Figure 5 shown, in some embodiments, a second air delivery channel 2313 is formed in the first liquid absorption member 231. The second air delivery channel 2313 may penetrate the first liquid absorption member 231 along the axial direction of the atomizer 1000. The second air delivery channels 2313 on the two first liquid absorption members 231 are coaxially arranged. Moreover, the second air delivery channel 2313 may be opposite to and communicate with the air inlet hole 211 on the base 210. The end of the ventilation groove 224 away from the air guide tube 221 may extend to the side wall 223 and extend to be opposite to the side surface of the second liquid absorption member 232. In addition, a transfer groove 2312 may be formed on one side of the first liquid absorption member 231 close to the side wall 223 where the ventilation groove 224 is located. The ventilation groove 224 may communicate with the first liquid absorption member 231 through the transfer groove 2312. In an embodiment, the pressure relief member 300 may communicate with the external environment through the air guide tube 221, the ventilation groove 224, the transfer groove 2312, the first liquid absorption member 231, the second air delivery channel 2313, and the air inlet hole 211 in sequence.

[0064] As Figure 2As shown, in some embodiments, an extension tube 212 is further protrudingly provided on one side of the base 210 facing the bracket 220, and the air inlet hole 211 can penetrate through the extension tube 212. One end of the extension tube 212 facing the liquid storage cavity 101 can be inserted into the first air delivery channel 2311 or the second air delivery channel 2313 of the first liquid suction member 231 near one side of the base 210. Thus, the probability of the atomization matrix absorbed in the liquid suction assembly 230 leaking out through the air inlet hole 211 can be reduced.

[0065] As Figure 2 and Figure 3 As shown, in some embodiments, the base unit 200 further includes a first seal 241, and the first seal 241 can be annular. The first seal 241 is disposed between the base 210 and the bracket 220, and can achieve sealing at the connection position between the base 210 and the bracket 220. In addition, the first seal 241 is also connected between the base 210 and the oil cup 100, and can achieve sealing at the connection position between the base 210 and the oil cup 100.

[0066] In some embodiments, a ring-shaped first connection groove 2411 is formed on one side of the first seal 241 facing the base 210. A ring-shaped convex rib 213 is protrudingly provided on one side of the base 210 facing the first seal 241. The convex rib 213 can be inserted into the first connection groove 2411, and the convex rib 213 can be in interference fit with the inner wall of the first connection groove 2411.

[0067] A ring-shaped second connection groove 2412 is formed on one side of the first seal 241 facing the bracket 220. One end of the side wall 223 away from the top plate 222 can be inserted into the second connection groove 2412, and the side wall 223 can be in interference fit with the inner wall of the second connection groove 2412. In addition, the surface of the first seal 241 away from the assembly cavity 201 can be in interference fit with the inner wall of the oil cup 100 near one side of the base unit 200. Thus, sealing at the connection position between the base 210 and the oil cup 100 can be achieved.

[0068] In some embodiments, a connection wall 214 is further protrudingly provided on the edge of the side of the base 210 facing away from the bracket 220, and the connection wall 214 can extend in the axial direction of the atomizer 1000 away from the bracket 220. In the embodiment, the connection wall 214 can be detachably connected to the oil cup 100 by means of snap connection or the like.

[0069] As Figure 2As shown, the base unit 200 further includes a second seal 242. The second seal 242 is sleeved on one end of the bracket 220 away from the base 210, and the second seal 242 is located on the side of the bracket 220 facing away from the base 210. In an embodiment, the second seal 242 may cover one surface of the assembly groove 2222 facing the liquid storage cavity 101. The peripheral side of the second seal 242 may extend to the peripheral side of the side wall 223 near one end of the top plate 222, that is, the peripheral side of the second seal 242 is inserted and sealingly abutted between the side wall 223 and the oil cup 100. Thus, the connection position between the bracket 220 and the oil cup 100 can be sealed by the second seal 242, avoiding the occurrence of oil leakage problems. In addition, an avoidance hole 2422 for the air guide pipe 221 to pass through is formed in the second seal 242. The air guide pipe 221 is disposed in the avoidance hole 2422 and extends into the liquid storage cavity 101.

[0070] As Figure 2 and Figure 6 As shown, the pressure relief member 300 may be disposed at one end of the air guide pipe 221 away from the top plate 222. In some embodiments, the pressure relief member 300 may include an airbag 310, and any part of the structural wall of the airbag 310 may be flexible. And the air port 312 of the airbag 310 is communicated with the air guide pipe 221. In some embodiments, the airbag 310 may be spherical.

[0071] In some embodiments, a part of the structural wall of the airbag 310 may also be set to be flexible so as to be elastically deformed. Another part of the structural wall of the airbag 310 is set to be rigid.

[0072] In some embodiments, a section of the structure of the airbag 310 near the air port 312 may be sleeved on one end of the air guide pipe 221 away from the top plate 222 and is in interference fit with the air guide pipe 221. Among them, the airbag 310 can be fixed on the air guide pipe 221 through frictional resistance and realizes detachable connection with the air guide pipe 221.

[0073] In some embodiments, the outer wall of the air guide pipe 221 for connecting one end of the airbag 310 is further configured with an annular anti-slip convex rib 2211. A section of the structure of the airbag 310 near the air port 312 may be sleeved on the anti-slip convex rib 2211, which can increase the frictional resistance between the airbag 310 and the air guide pipe 221, improve the connection stability between the airbag 310 and the air guide pipe 221, and reduce the risk of the airbag 310 detaching from the air guide pipe 221.

[0074] As Figure 2 and Figure 7As shown, in some embodiments, a section of the structure of the airbag 310 near the air inlet 312 may be configured with a connecting pipe 311, and internal threads may be provided on the inner wall of the connecting pipe 311. One end of the air guide pipe 221 away from the top plate 222 may be configured with external threads adapted to the internal threads. The connecting pipe 311 of the airbag 310 may be detachably connected to the air guide pipe 221 by a threaded connection.

[0075] In some embodiments, the airbag 310 and the air guide pipe 221 may also be fixedly connected by means such as bonding, heat fusion connection or integral molding, that is, they are non-detachable after being connected.

[0076] As Figure 8 shown, in some embodiments, the pressure relief member 300 may include a collapsible pleated structure 320, a structure similar to that of an accordion, so as to perform elastic deformation. When the pleated structure 320 is squeezed, the pleated structure 320 can be folded and contracted. When the pleated structure 320 expands, the pleated structure 320 can be unfolded and elongated.

[0077] As Figure 1 and Figure 2 shown, in some embodiments, when the liquid storage chamber 101 is in a full liquid state, the pressure relief member 300 may be in a natural state, that is, the pressure relief member 300 is filled with gas and the surface of the pressure relief member 300 is in a natural stretched state. In addition, the maximum deformation volume difference of the pressure relief member 300 is greater than or equal to the maximum expansion and contraction volume difference of the gas with a volume of one-third of the volume of the liquid storage chamber 101.

[0078] That is, the volume of the pressure relief member 300 and the volume of the liquid storage chamber 101 also satisfy:

[0079] V1 = V1′ - V1″;

[0080] wherein, V1′ represents the maximum volume after the pressure relief member 300 expands, and V1″ represents the minimum volume after the pressure relief member 300 contracts. V2 represents the volume of the liquid storage chamber 101. Exemplarily, when the user's usage environment temperature is between -20°C and 60°C, the volume after the pressure relief member 300 expands in the usage environment of -20°C may be V1′, the volume after the pressure relief member 300 contracts in the usage environment of 60°C may be V1″, and the maximum deformation volume difference of the pressure relief member 300 may be the difference between V1′ and V1″. The volume of the gas with a volume of one-third of the volume of the liquid storage chamber 101 after contraction in the usage environment of -20°C may be V2′, the volume of the gas with a volume of one-third of the volume of the liquid storage chamber 101 after expansion in the usage environment of 60°C may be V2″, and the maximum expansion and contraction volume difference of the gas with a volume of one-third of the volume of the liquid storage chamber 101 may be the difference between V2″ and V2′.

[0081] In this application, it is known from experiments that when two-thirds of the atomization matrix in the liquid storage chamber 101 remains, the atomizer 1000 is most prone to leakage problems. In the embodiment, the volume of the pressure relief member 300 and the volume of the liquid storage chamber 101 satisfy the above relationship, so that the deformation of the pressure relief member 300 can meet the need for air pressure regulation in the liquid storage chamber 101, effectively reducing the probability of oil leakage problems occurring in the atomizer 1000.

[0082] As Figure 1 、 Figure 9 and Figure 10 shown, in some embodiments, a mouthpiece 500 is further disposed at one end of the oil cup 100 away from the base unit 200. The atomizer 1000 in the embodiment of the present application may be a structure in which the mouthpiece 500 and the oil cup 100 are integrated.

[0083] A gas delivery pipe 110 is further disposed at one end of the oil cup 100 close to the mouthpiece 500. The gas delivery pipe 110 may be disposed inside the oil cup 100, and one end of the gas delivery pipe 110 may be communicated with the mouthpiece 500.

[0084] The atomizer 1000 further includes an atomization core assembly 400. The atomization core assembly 400 may be disposed in the oil cup 100 and connected to one end of the gas delivery pipe 110 away from the mouthpiece 500. One end of the atomization core assembly 400 away from the gas delivery pipe 110 may be inserted into the assembly groove 2222 of the bracket 220 and in interference fit with the side of the second seal 242 facing away from the bracket 220, so as to achieve the sealing of the connection position between the atomization core assembly 400 and the bracket 220.

[0085] In some embodiments, the atomization core assembly 400 may include an assembly pipe 420, a liquid guiding member 430, and an atomization core 410. Among them, the liquid guiding member 430 may be fixedly sleeved on the periphery of the atomization core 410, and the assembly pipe 420 is sleeved on the side of the liquid guiding member 430 away from the atomization core 410. In some embodiments, the liquid guiding member 430 may be made of an oil storage material such as a cotton sheet or a sponge.

[0086] In the embodiment, one end of the assembly pipe 420 facing the mouthpiece 500 may protrude relative to one end of the liquid guiding member 430 facing the mouthpiece 500. One end of the assembly pipe 420 facing the mouthpiece 500 may be sleeved on the periphery of one end of the gas delivery pipe 110 away from the mouthpiece 500. In addition, a third seal 610 is clamped between the gas delivery pipe 110 and the assembly pipe 420. The third seal 610 can be compressed between the gas delivery pipe 110 and the assembly pipe 420. On the one hand, it can achieve the fixed connection between the gas delivery pipe 110 and the atomization core assembly 400, and on the other hand, it can achieve the sealing of the connection position between the gas delivery pipe 110 and the atomization core assembly 400.

[0087] In the embodiment, one end of the assembly tube 420 away from the gas delivery tube 110 can be inserted into the assembly groove 2222. And the second seal 242 can be in contact with the end face of the end of the assembly tube 420 away from the gas delivery tube 110 and the surface of the assembly tube 420 on the side away from the atomization core 410 to achieve a sealed connection.

[0088] In addition, a liquid inlet hole 421 communicating with the liquid storage cavity 101 is formed in the assembly tube 420, and one end of the liquid inlet hole 421 away from the liquid storage cavity 101 can be communicated with the atomization core 410 through a liquid guiding member 430. In the embodiment, an air flow channel 411 extending along the axis of the atomizer 1000 can be formed inside the atomization core 410, and one end of the air flow channel 411 can be communicated with the gas delivery tube 110.

[0089] During use, the atomization matrix in the liquid storage cavity 101 can be sequentially transmitted to the atomization core 410 through the liquid inlet hole 421 and the liquid guiding member 430. The atomization core 410 can heat and atomize the atomization matrix and generate an aerosol. The aerosol can be sequentially transmitted to the mouthpiece 500 through the air flow channel 411 and the gas delivery tube 110 for the user to suck.

[0090] In the embodiment, when the gas in the cavity of the liquid storage cavity 101 expands and increases in pressure due to other factors, the pressure relief member 300 can undergo elastic deformation and contract to release part of the cavity volume and reduce the air pressure in the cavity. Thus, the risk that the remaining atomization matrix in the liquid storage cavity 101 is extruded out of the liquid storage cavity 101 in large quantities under the action of positive pressure through the liquid inlet hole 421 and leaks can be reduced, and the probability of liquid leakage of the atomizer 1000 can be reduced.

[0091] When the gas in the cavity contracts due to other factors to create a negative pressure environment, under the action of the air pressure difference, the gas in the external environment can enter the pressure relief member 300 through the air guide tube 221, causing the pressure relief member 300 to undergo elastic deformation and expand to occupy part of the cavity volume. Thus, the gas in the cavity can be compressed, the air pressure in the cavity can be increased and tend to the atmospheric pressure. Furthermore, it can ensure that the remaining atomization matrix in the liquid storage cavity 101 can be smoothly delivered to the atomization core 410 through the liquid inlet hole 421 for atomization, and the probability of the atomization core 410 experiencing the problem of burnt core can be reduced.

[0092] Such as Figure 1 、 Figure 2 、 Figure 6 and Figure 10As shown, in some embodiments, the second sealing member 242 is further provided with a second air hole 2421, which can be communicated with the air flow channel 411 and the first air hole 225, respectively. Accordingly, the air inlet 211, the first air delivery channel 2311 (or the second air delivery channel 2313), the first air hole 225 and the second air hole 2421 can form an air inlet channel 900 connected to the air flow channel 411. Thus, the external gas can enter the liquid storage chamber 101 through the air inlet channel 900, the air flow channel 411, the atomizer core 410, the liquid guide 430 and the liquid inlet hole 421 in sequence to further balance the air pressure in the liquid storage chamber 101, ensure that the atomization matrix in the liquid storage chamber 101 can be smoothly delivered to the atomizer core 410 for atomization, and reduce the probability of the atomizer core 410 having a core-burning problem.

[0093] In some embodiments, the pressure relief member 300 is disposed at one end of the liquid storage chamber 101 away from the liquid inlet hole 421. During the use of the atomizer 1000, at least a portion of the pressure relief member 300 can be exposed to the cavity of the liquid storage chamber 101 more quickly, so as to regulate the air pressure in the liquid storage chamber 101. On the one hand, the risk of leakage of the atomizer 1000 can be reduced. On the other hand, it can also ensure that the atomized matrix in the liquid storage chamber 101 can be smoothly output, ensuring the normal use of the atomizer 1000. In this way, the user experience can be improved.

[0094] like Figure 2 and Figure 9 As shown, the atomizer 1000 also includes a circuit board 710, which can be arranged in the assembly cavity 201 of the base unit 200 and is located between the base 210 and the liquid absorption assembly 230. In the embodiment, the circuit board 710 can be electrically connected to the atomizer core 410 through a structure such as a wire. In addition, a pole 711 is configured on the side of the circuit board 710 facing the base 210, and the pole 711 can be penetrated in the base 210 along the axial direction of the atomizer 1000, and exposed relative to the side of the base 210 away from the bracket 220. During use, the pole 711 can be electrically connected to the power supply structure, so that the atomizer core 410 can be powered by the power supply structure.

[0095] In some embodiments, the atomizer 1000 further includes a fourth sealing member 620, which may be embedded in the base 210, and the fourth sealing member 620 may be exposed relative to the side of the base 210 facing the bracket 220 and the side of the base 210 facing away from the bracket 220. The pole 711 may be inserted into the fourth sealing member 620 and have an interference fit with the fourth sealing member 620, thereby achieving fixation of the pole 711 and sealing of the installation position of the pole 711 and the base 210.

[0096] like Figure 2As shown, the atomizer 1000 further includes a magnetic member 720. The magnetic member 720 can be embedded in the side of the base 210 facing away from the bracket 220, and the magnetic member 720 can be exposed relative to the side of the base 210 facing away from the bracket 220. During use, the magnetic member 720 can be magnetically connected to the power supply structure, thereby realizing the mechanical connection between the atomizer 1000 and the power supply structure.

[0097] In some embodiments, the magnetic member 720 can be selected from a magnet or an electromagnet. When the magnetic member 720 is an electromagnet, the magnetic member 720 can be electrically connected to the circuit board 710.

[0098] As Figure 1 and Figure 11 As shown, in some embodiments, a liquid injection hole 120 communicating with the liquid storage cavity 101 is further formed on one side of the oil cup 100. The user can replenish the liquid storage cavity 101 through the liquid injection hole 120. When the liquid injection hole 120 is not in use, the liquid injection hole 120 can be sealed by a liquid injection plug 800. In the embodiment, the liquid injection plug 800 is further connected with a connecting column 810. One end of the connecting column 810 can be limited to the side of the oil cup 100 close to the liquid storage cavity 101, which can prevent the liquid injection plug 800 from being lost. In addition, the connecting column 810 can rotate relative to the oil cup 100, so that the user can move the liquid injection plug 800 to open the liquid injection hole 120.

[0099] In some embodiments, the present application further provides an atomization device, which may include a power supply assembly and the atomizer 1000 provided in the embodiment. Among them, the power supply assembly can be connected to one end of the atomizer 1000 close to the base 210 in a magnetic attraction manner, and the power supply assembly is electrically connected to the pole column 711 to supply power to the atomizer 1000.
