[0028] Specifically, atomization component 1 includes first liquid storage part 11, check valve 12 and atomization core 13, first liquid storage part 11 includes liquid storage tube 111, breather tube 112, sealing seat 113 and connecting cover 114, first liquid storage cavity 1111 is formed in liquid storage tube 111, and first liquid storage cavity 1111 is used to store first atomization liquid. The first atomization liquid can include propylene glycol, glycerol and essence and spice materials. It can be understood that, as long as it can be atomized to form smoke, the chemical composition of the first atomization liquid is not specifically limited here.

[0029] Liquid injection hole 1112 and exhaust hole 1113 are provided at the cavity wall of first liquid storage cavity 1111. Breather tube 112 is located in liquid storage tube 111, the first end of breather tube 112 is connected with liquid storage tube 111, the second end of breather tube 112 is connected with sealing seat 113, and the side wall of breather tube 112 is provided with liquid outlet hole 1121 communicated with first liquid storage cavity 1111.

[0030] Sealing seat 113 is inserted into one end of liquid storage tube 111 and extends into connecting cover 114 to prevent leakage of the first atomization liquid, and sealing seat 113 can be made of silica gel or rubber. The end face of sealing seat 113 facing power supply component 3 is provided with first fixing groove 1131 and second fixing groove 1132. Connecting cover 114 is covered on the end face of one end of liquid storage tube 111 and connected with liquid storage tube 111, and connecting cover 114 is provided with first docking hole 1141 and second docking hole 1142, the position of first docking hole 1141 corresponds to second fixing groove 1132, and first docking hole 1141 and first fixing groove 1131 constitute the first docking groove 101. The position of second docking hole 1142 corresponds to second fixing groove 1132, and second docking hole 1142 and second fixing groove 1132 constitute the second docking groove 102.

[0031] The first liquid storage component 11 further comprises an elastic sealing sheet 15 and a fixing ring 16. The elastic sealing sheet 15 is located in the first liquid storage cavity 1111 and covers the hole of the liquid injection hole 1112 facing the first liquid storage cavity 1111. The elastic sealing sheet 15 is provided with a cutout for inserting the liquid injection equipment into the first liquid storage cavity 1111 during liquid injection. The fixing ring 16 is fixed in the first liquid storage cavity 1111 and abuts against the elastic sealing sheet 15 to prevent the elastic sealing sheet 15 from falling off.

[0032] During production, the first atomized liquid can be injected into the first liquid storage cavity 1111 through the liquid injection hole 1112 and the cutout of the elastic sealing sheet 15. After the liquid injection is completed, the first atomized liquid is blocked by the elastic sealing sheet 15, thereby avoiding leakage. By providing the exhaust hole 1113, the air pressure in the first liquid storage cavity 1111 during liquid injection is prevented from being too high, thereby reducing the probability of leakage of the first atomized liquid from the air passage 112. Preferably, the cross-sectional area of the exhaust hole 1113 is smaller than that of the liquid injection hole 1112, thereby reducing the probability of leakage during use.

[0033] The first liquid storage component 11 further comprises an elastic sealing plug 17 and a suction nozzle 18. The elastic sealing plug 17 is located in the suction nozzle 18 and covers the hole of the liquid injection hole 1112 away from the first liquid storage cavity 1111 and the hole of the exhaust hole 1113 away from the first liquid storage cavity 1111, thereby better sealing the liquid storage tube 111. The suction nozzle 18 is connected to the liquid storage tube 111 and communicates with the air passage 112, and a user sucks the smoke through the suction nozzle 18. The one-way valve 12 is installed at the cavity wall of the first liquid storage cavity 1111 for guiding the second atomized liquid of the liquid supply assembly 2 into the first liquid storage cavity 1111 and preventing the first atomized liquid from flowing towards the liquid supply assembly 2.

[0034] The atomizing core 13 is located in the first liquid storage cavity 1111 for atomizing the first atomized liquid. The atomizing core 13 comprises a porous elastic foam liquid blocking tube 131, a fixing tube 132, a porous liquid guiding sheet 133 and an electric heating element 134. The porous elastic foam liquid blocking tube 131 is located in the air passage 112 and is sleeved outside the fixing tube 132. The porous elastic foam liquid blocking tube 131 can be a polyurethane foam tube, and the material thereof is not limited as long as it is made of a porous material with elasticity, which can better seal the liquid outlet hole 1121. The outer wall of the porous elastic foam liquid blocking tube 131 covers the liquid outlet hole 1121 to prevent the atomized liquid at the liquid outlet hole 1121 from excessively flowing into the fixing tube 132. The bottom end of the fixing tube 132 is connected to the sealing seat 13, and the side wall of the fixing tube 132 is provided with a liquid guiding hole 1321.

[0035] The porous liquid guide sheet 133 is at least partially located in the fixed tube 132, used for adsorbing the atomized liquid at the liquid guide hole 1321, and the porous liquid guide sheet 133 is spaced apart from the porous elastic foam liquid blocking tube 131. The electric heating element 134 is in contact with the porous liquid guide sheet 133, used for atomizing the atomized liquid at the porous liquid guide sheet 133. The porous liquid guide sheet 133 can be made of fiber or the like, which can be wound into a tubular structure. The electric heating element 134 can be an electric heating wire or an electric heating net or the like.

[0036] Since the porous elastic foam liquid blocking tube 131 is sleeved outside the fixed tube 132, and the outer wall of the porous elastic foam liquid blocking tube 131 covers the liquid outlet hole 1121, so as to block the first atomized liquid at the liquid outlet hole 1121 from flowing into the fixed tube 132 excessively, and the porous liquid guide sheet 133 is spaced apart from the porous elastic foam liquid blocking tube 131, the porous elastic foam liquid blocking tube 131 itself can buffer the flow of the first atomized liquid to some extent, so as to reduce the flowability of the atomized liquid, and slow down the speed of the first atomized liquid flowing into the porous liquid guide sheet 133.

[0037] Secondly, the porous elastic foam liquid blocking tube 131 itself is distributed with a plurality of micropore structures, when the atomized liquid passes through the micropore structures, an oil film is formed at the micropore structures, and the surface tension generated by the oil film can further reduce the flowability of the atomized liquid, so as to further slow down the speed of the first atomized liquid flowing into the porous liquid guide sheet 133, thereby effectively reducing the problem of "flying liquid" of the atomizing core 13 caused by the atomized liquid flowing in too fast during the user's suction use. It can be understood that as long as the first atomized liquid can be atomized, the structure of the atomizing core 13 is not limited.

[0038] The end face of the liquid supply assembly 2 is provided with a third butt joint groove 201 extending along the transverse direction of the electronic atomizing device, and the third butt joint groove 201 is provided with a first buckling protrusion 202. Specifically, the liquid supply assembly 2 comprises a second liquid storage component 21 and a pump liquid component 22, the second liquid storage component 21 is provided with a second liquid storage cavity 203 and a liquid guide cavity 204, the second liquid storage cavity 203 is used for storing a second atomized liquid, and the chemical composition of the second atomized liquid can be the same as or different from that of the first atomized liquid, which is not limited here.

[0039] The liquid guide cavity 204 is in communication with the first liquid storage cavity 1111 and the second liquid storage cavity 203. The pump liquid component 22 is at least partially inserted into the liquid guide cavity 204, used for pumping the second atomized liquid in the second liquid storage cavity 203 into the first liquid storage cavity 1111. Preferably, the liquid guide cavity 204 is located in the second liquid storage cavity 203 or the liquid guide cavity 204 and the second liquid storage cavity 203 are arranged side by side, so as to make the second atomized liquid flow into the liquid guide cavity 204 automatically by gravity as much as possible, and then the second atomized liquid can be quickly pumped into the first liquid storage cavity 1111.

[0040] Specifically, the second liquid storage component 21 comprises a containing shell 211, a sealing cover 212 and a limiting ring 213. The containing shell 211 is provided with the second liquid storage cavity 203 and the liquid guide cavity 204. The second liquid storage cavity 203 is in communication with the first end face of the containing shell 211, and the liquid guide cavity 204 is in communication with the second end face of the containing shell 211. The first end face of the containing shell 211 is arranged opposite to the second end face of the containing shell 211. The sealing cover 212 is arranged at the cavity opening of the second liquid storage cavity 203, and the end face of the sealing cover 212 is provided with the third butt joint groove 201. The limiting ring 213 is inserted at the cavity opening of the liquid guide cavity 204, and is used to prevent the pump liquid component 22 from falling off from the liquid guide cavity 204.

[0041] The cavity wall of the liquid guide cavity 204 is provided with a liquid inlet hole 2041 and a liquid outlet hole 2042. The liquid inlet hole 2041 is in communication with the second liquid storage cavity 203, and the liquid outlet hole 2042 is used to discharge the second atomized liquid flowing from the second liquid storage cavity 203 into the liquid guide cavity 204 into the first liquid storage cavity 1111. When the electronic atomization device is vertically placed with the suction nozzle upward, the height of the position where the liquid outlet hole 2042 is located is lower than the top wall of the second liquid storage cavity 203, thereby facilitating the discharge of the second atomized liquid into the first liquid storage cavity 1111.

[0042] In addition, the cavity wall of the liquid guide cavity 204 is further provided with a gas guide hole 2043, which is in communication with the second liquid storage cavity 203. The one-way valve 12 extends into the liquid outlet hole 2042, which is in communication with the liquid outlet hole 2042, and is used to prevent the liquid in the first liquid storage cavity 1111 from flowing into the liquid outlet hole 2042. Since the one-way valve 12 extends into the liquid outlet hole 2042, the up and down movement of the liquid supply assembly 2 can be prevented, and the liquid supply assembly 2 can be prevented from falling off due to vibration, thereby improving the reliability of the structure.

[0043] The pump liquid part 22 comprises a piston 221, a connecting rod 222, an elastic member 223, a liquid blocking ball 224 and a liquid blocking ring 225, the limiting ring 213 abuts against the piston 221, the piston 221 is movably connected with the liquid guide cavity 204, one end of the piston 221 is connected with a button 226, and the piston 221 can be formed by one or more parts in combination. Preferably, a sealing ring is arranged on the outer circumferential surface of the piston 221 and tightly matches with the liquid guide cavity 204. The first end of the connecting rod 222 is a closed end, the first end of the connecting rod 222 abuts against the piston 221, and the second end of the connecting rod 222 abuts against the first end of the elastic member 223. The second end of the elastic member 223 abuts against the cavity wall of the liquid guide cavity 204, and the elastic member 223 can be a spring or a spring piece. The liquid blocking ball 224 is located at the hole of the liquid inlet hole 2041. The liquid blocking ring 225 is sleeved on the connecting rod 222 and connected with the cavity wall of the second liquid storage cavity 203, a liquid guide gap is formed between the liquid blocking ring 225 and the connecting rod 222, the hole of the liquid outlet hole 2042, which is opposite to the hole of the first liquid storage cavity 1111, is located between the piston 221 and the liquid blocking ring 225, and the liquid outlet hole 2042 is communicated with the liquid inlet hole 2041 through the liquid guide gap.

[0044] The end surface of the connecting rod 222 is provided with a flow dividing groove 2221 extending along the axial direction of the connecting rod 222, the flow dividing groove 2221 is communicated with the liquid inlet hole 2041, the side wall of the flow dividing groove 2221 is provided with a flow dividing hole 2222, and the flow dividing hole 2222 is communicated with the liquid guide gap. The outer circumferential surface of the connecting rod 222 is provided with an annular liquid pushing part 2223, and the liquid pushing part 2223 is located on the side of the liquid blocking ring 225, which is away from the piston 221. The end surface of the connecting rod 222, which is away from the piston 221, is provided with an annular limiting part 2224, and the limiting part 2224 is sleeved on one end of the elastic member 223, so that the elastic member 223 is positioned more reliably.

[0045] The electronic atomization device comprises a first state and a second state, in the first state, the piston 221 covers the hole of the air guide hole 2043, which is away from the second liquid storage cavity 203, in the second state, the piston 221 is spaced apart from the air guide hole 2043, the air guide hole 2043 is communicated with the outside of the electronic atomization device through the liquid guide cavity 204, so that the second atomization liquid can more easily flow into the liquid guide cavity 204.

[0046] In use, when the first atomized liquid is exhausted, the user presses the button 226, and the elastic member 223 is compressed, the piston 221 and the connecting rod 222 move together in the direction of the liquid blocking ball 224, at the same time, the gas in the liquid guide cavity 204 flows into the second storage liquid cavity 203 through the liquid inlet hole 2041, because the density of the gas is smaller than the density of the second atomized liquid, so the gas flows into the second storage liquid cavity 203 and flows towards the top wall of the second storage liquid cavity 203. When the piston 221 is spaced apart from the gas guide hole 2043, the electronic atomization device enters the second state, the gas guide hole 2043 is in communication with the outside of the electronic atomization device through the liquid guide cavity 204, and the gas in the second storage liquid cavity 203 can flow out from the gas guide hole 2043, so that the user is more labor-saving when pressing the button 226, and it is also more beneficial for the second atomized liquid to flow into the liquid guide cavity 204.

[0047] When the user stops applying force to the button 226, the connecting rod 222 and the piston 221 move in the direction away from the liquid blocking ball 224 under the elastic restoring force of the elastic member 223, at this time, the region of the lower end of the liquid guide cavity 204 storing air is in a negative pressure state, therefore, the second atomized liquid in the second storage liquid cavity 203 flows into the liquid guide cavity 204 through the liquid inlet hole 2041. The liquid pushing part 2223 pushes the second atomized liquid in the liquid guide cavity 204 out of the liquid guide gap and flows into the first storage liquid cavity 1111 through the liquid outlet hole 2042 and the one-way valve 12, thereby realizing the replenishment of the atomized liquid. Through the cooperation of the flow dividing groove 2221 and the flow dividing hole 2222, the second atomized liquid flowing out of the liquid inlet hole 2041 can quickly flow to the liquid outlet hole 2042 through the flow dividing groove 2221 and the flow dividing hole 2222. By providing the liquid pushing part 2223, the movement of the fluid in the liquid guide cavity 204 is better driven.

The battery 33 is located in the mounting shell 31 and is electrically connected to the controller 34. The controller 34 is located in the mounting shell 31 and is electrically connected to the first electrode 35 and the second electrode 36.

[0049] The controller 34 is configured to control the battery 33 to supply power to the atomization core 13, so that the atomization core 13 atomizes the first atomization liquid to form smoke for a user to smoke. The first electrode 35 is connected to the support 32 and extends into the first connecting groove 101 through the first connecting hole 1141, and the second electrode 36 is connected to the support 32 and extends into the second connecting groove 102 through the second connecting hole 1142.
