[0047] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0048] Figure 1-2 The electronic atomization device in the first embodiment of the present invention is shown. The electronic atomization device can be used for atomization of liquid matrices such as smoke liquid and liquid medicine, and can include a host 2 and an atomizer 1 installed on the host 2. The host 2 can include a housing 26 and electronic components such as a battery and a control circuit arranged in the housing 26. The housing 26 can be provided with a cavity 261 for accommodating the atomizer 1. The electronic components can supply power to the atomizer 1 and control the operation of the electronic atomization device. The atomizer 1 can be installed in the cavity 261 in a detachable manner, which can be used to store liquid matrices such as smoke liquid and liquid medicine, and atomize the liquid matrices for users to inhale.

[0049] like Figure 3 As shown, in some embodiments, the atomizer 1 may include a first shell 16, a second shell 17, and an atomizer assembly 14. The second shell 17 is disposed on an open end of the first shell 16, and a liquid storage chamber 11 and an atomizer chamber 15 are formed between the first shell 16 and the second shell 17. The liquid storage chamber 11 is used to contain liquid substrates such as tobacco liquid and liquid medicine. The atomizer assembly 14 is disposed in the atomizer chamber 15 and is connected to the liquid storage chamber 11 to heat and atomize the liquid substrate in the liquid storage chamber 11.

[0050] In some embodiments, the first housing 16 may include an open end 161 at the bottom, a nozzle end 163 opposite to the open end 161, and a cylindrical side wall 162 connected between the open end 161 and the nozzle end 163. The second housing 17 may be fitted at the open end 161, and the atomizer assembly 14 may be disposed on the second housing 17 and located in the first housing 16.

[0051] In some embodiments, the atomizer 1 may further include a normally closed first liquid injection transmission module 12 and a normally closed exhaust module 13 connected to the liquid storage chamber 11. The first liquid injection transmission module 12 and the exhaust module 13 can be connected under the action of an external force to be respectively used for the injection and exhaust of the liquid storage chamber 11. The first liquid injection transmission module 12 and the exhaust module 13 can both be elastically movable modules. When the atomizer 1 and the host 2 are separated from each other, the first liquid injection transmission module 12 and the exhaust module 13 are both kept in a closed state to ensure that the atomizer 1 does not leak when in a single state.

[0052] The first liquid injection and delivery module 12 may be disposed on the second housing 17, and the exhaust module 13 may be disposed on the cylindrical side wall 162, and the exhaust module 13 is located higher than the first liquid injection and delivery module 12, so that the liquid matrix in the liquid storage chamber 11 is not easy to leak out of the exhaust module 13. In some embodiments, the exhaust module 13 may be disposed in a horizontal direction, and the first liquid injection and delivery module 12 may be disposed in a vertical direction.

[0053] like Figure 4 As shown, in some embodiments, the host 2 may also include a liquid storage module 21 and a normally closed second liquid injection transmission module 22 connected to the liquid storage module 21. The liquid storage module 21 can be detachably arranged in the housing 26 for storing liquid matrix and supplying liquid to the liquid storage chamber 11. When the user goes out, the liquid storage module 21 filled with liquid matrix can be loaded into the electronic atomization device, so as to carry enough liquid matrix for the user to use. The liquid storage module 21 can generally be a liquid storage bottle and can be installed at the bottom of the housing 26. When the second liquid injection transmission module 22 is turned on under the action of external force, the second liquid injection transmission module 22 is used to output the liquid matrix of the liquid storage module 21 to the liquid storage chamber 11. The second liquid injection transmission module 22 can be an elastic active module. When the host 2 and the atomizer 1 are separated from each other, the second liquid injection transmission module 22 remains in a closed state to ensure that the host 2 does not leak in a single state.

[0054] The second liquid injection delivery module 22 is mounted on the housing 26, and is arranged corresponding to the first liquid injection delivery module 12. The top of the housing 26 is provided with an opening, and the atomizer 1 can be installed in the cavity 261 through the opening. The second liquid injection delivery module 22 can be installed at the bottom of the cavity 261, and the position of the second liquid injection delivery module 22 can be higher than the liquid storage module 21. Figure 6As shown, after the atomizer 1 and the host 2 are assembled, the first liquid injection transmission module 12 and the second liquid injection transmission module 22 interact and communicate with each other, thereby connecting the liquid storage chamber 11 with the liquid storage module 21 .

[0055] Combination Figure 3-7 As shown, in some embodiments, the first liquid injection delivery module 12 may include a first inner tube 122 and a first elastic member 125 connected to the first inner tube 122. A first liquid inlet 121 connected to the liquid storage chamber 11 is provided on the side wall of the first inner tube 122, and the first inner tube 122 can move back and forth between a first position and a second position relative to the liquid storage chamber 11.

[0056] In some embodiments, the second liquid injection transmission module 22 may include a second inner tube 222 and a second elastic member 225 connected to the second inner tube 222. The second inner tube 222 is disposed corresponding to the first inner tube 122, and a second liquid inlet 221 connected to the liquid storage module 21 is provided on the side wall of the second inner tube 222. The second inner tube 222 can move back and forth between the third position and the fourth position relative to the liquid storage module 21.

[0057] When the atomizer 1 is separated from the host 2, the first inner tube 122 is elastically maintained in the first position under the action of the first elastic member 125, so that the first liquid inlet 121 is isolated from the liquid storage chamber 11, and the second inner tube 222 is elastically maintained in the third position under the action of the second elastic member 225, so that the second liquid inlet 221 is isolated from the liquid storage module 21, thereby closing the first liquid injection transmission module 12 and the second liquid injection transmission module 22 to ensure that the atomizer 1 and the host 2 do not leak when they are alone.

[0058] When the atomizer 1 is combined with the host 2, the first inner tube 122 and the second inner tube 222 abut against and push each other, so that the first inner tube 122 moves from the first position to the second position, thereby connecting the first liquid inlet 121 with the liquid storage chamber 11, and the second inner tube 222 moves from the third position to the fourth position, thereby connecting the second liquid inlet 221 with the liquid storage module 21.

[0059] In some embodiments, the first liquid injection transmission module 12 may further include a first sleeve 123 and a first sealing member 124. The first sleeve 123 may be mounted on the second housing 17, and the first inner tube 122 is axially disposed in the first sleeve 123, and may move back and forth between a first position away from the liquid storage chamber 11 and a second position close to the liquid storage chamber 11 relative to the first sleeve 123. A first annular protrusion 1232 may be disposed in the first sleeve 123, and the inner hole of the first annular protrusion 1232 forms a first opening 1231. The first sealing member 124 is mounted on the outside of the first inner tube 122, and is fitted at the first opening 1231 to seal the first opening 1231, thereby isolating the first liquid inlet 121 from the liquid storage chamber 11. The first elastic member 125 may be disposed between the first sleeve 123 and the first inner tube 122.

[0060] In some embodiments, the second liquid injection transmission module 22 may further include an outer tube 228, a second sleeve 223, and a second sealing member 224. The outer tube 228 is installed at the bottom of the cavity 261 and communicates with the liquid storage module 21. The second sleeve 223 is axially arranged in the outer tube 228. The second inner tube 222 is axially arranged in the second sleeve 223 and can move back and forth between a third position away from the liquid storage module 21 and a fourth position close to the liquid storage module 21 relative to the second sleeve 223. A second annular protrusion 2232 may be provided in the second sleeve 223, and the inner hole of the second annular protrusion 2232 forms a second opening 2231, and the second opening 2231 is communicated with the outer tube 228 and the liquid storage module 21. The second sealing member 224 is installed outside the second inner tube 222, and it cooperates at the second opening 2231 to seal the second opening 2231, thereby isolating the second liquid inlet 221 from the liquid storage module 21. The second elastic member 225 may be disposed between the second sleeve 223 and the second inner tube 222. Both the first sealing member 124 and the second sealing member 224 may be made of soft materials, which is beneficial to improving the sealing effect.

[0061] When the atomizer 1 and the host 2 are separated from each other, the first inner tube 122 is elastically maintained in the first position under the action of the first elastic member 125, the first sealing member 124 abuts against the first annular protrusion 1232 to seal the first opening 1231, and the first liquid inlet 121 is located on the outside of the first opening 1231 (the side away from the liquid storage chamber 11) and is isolated from the liquid storage chamber 11; the second inner tube 222 is elastically maintained in the third position under the action of the second elastic member 225, the second sealing member 224 abuts against the second annular protrusion 2232 to seal the second opening 2231, and the second liquid inlet 221 is located on the outside of the second opening 2231 (the side away from the liquid storage module 21) and is isolated from the liquid storage module 21.

[0062] When the atomizer 1 is pressed to connect with the host 2, the first inner tube 122 and the second inner tube 222 abut against and push each other, so that the first inner tube 122 moves from the first position to the second position, the first sealing member 124 moves away from the first annular protrusion 1232, and the first liquid inlet 121 moves to the inner side of the first opening 1231 (the side opposite to the liquid storage chamber 11) to communicate with the liquid storage chamber 11; the second inner tube 222 moves from the third position to the fourth position, the second sealing member 224 moves away from the second annular protrusion 2232, the second liquid inlet 221 moves to the inner side of the second opening 2231 (the side opposite to the liquid storage module 21) to communicate with the liquid storage module 21, the first inner tube 122 is connected to the second inner tube 222, and the liquid storage chamber 11 is connected to the liquid storage module 21.

[0063] In some embodiments, the end (outer end) of the first inner tube 122 away from the liquid storage chamber 11 can extend out of the first outer tube 123, and the end (outer end) of the second inner tube 222 away from the liquid storage module 21 can extend out of the second outer tube 223, so that the first inner tube 122 and the second inner tube 222 can abut against and push each other. Further, the outer end surface of the first inner tube 122 can be flush with the outer end surface of the second shell 17 or slightly lower than the outer end surface of the second shell 17, and the outer end of the second inner tube 222 can extend out of the bottom of the cavity 261.

[0064] In some embodiments, the inner circle of the end of the first sleeve 123 opposite to the liquid storage chamber 11 extends radially inward to form a first annular protrusion 1232, and the first seal 124 can be sealed with the inner side surface (the side surface opposite to the liquid storage chamber 11) of the first annular protrusion 1232 to prevent leakage. The inner circle of the end of the second sleeve 223 opposite to the liquid storage module 21 extends radially inward to form a second annular protrusion 2232, and the second seal 224 can be sealed with the inner side surface (the side surface opposite to the liquid storage module 21) of the second annular protrusion 2232 to prevent leakage.

[0065] The end (inner end) of the first inner tube 122 opposite to the liquid storage chamber 11 can extend out of the first sleeve 123 and the inner end is closed, which may include a first tube body 1221 and a first mounting seat 1222. In some embodiments, the inner end of the first tube body 1221 is open, and the first mounting seat 1222 is plugged at the inner end of the first tube body 1221 to close the inner end of the first tube body 1221. The first mounting seat 1222 can usually be made of a soft material to improve the sealing effect. The first mounting seat 1222 can be stepped, and the small end of the first mounting seat 1222 is plugged at the inner end of the first tube body 1221. The outer diameter of the large end of the first mounting seat 1222 is larger than the outer diameter of the inner end of the first tube body 1221, so that a positioning step is formed between the large end of the first mounting seat 1222 and the inner end of the first tube body 1221, and the first sealing member 124 is sleeved outside the first tube body 1221 and its inner side surface can be against the positioning step. In other embodiments, the first sealing member 124 may also be sleeved outside the large end of the first mounting seat 1222. In other embodiments, the inner end of the first tube body 1221 may also be closed, and the first mounting seat 1222 may be sleeved on the inner end of the first tube body 1221.

[0066] The first elastic member 125 may be sleeved outside the first inner tube 122. A first positioning platform 1224 may be provided outside the first inner tube 122 for the first elastic member 125 to abut against, and both ends of the first elastic member 125 abut against the first annular protrusion 1232 and the first positioning platform 1224, respectively. When the atomizer 1 and the host 2 are assembled, the first inner tube 122 is pushed to move from the first position to the second position, and the first elastic member 125 is compressed; when the atomizer 1 and the host 2 are detached from each other, the inward force on the first inner tube 122 disappears, and the first elastic member 125 resets the first inner tube 122 outward to the first position.

[0067] The end (inner end) of the second inner tube 222 opposite to the liquid storage module 21 can extend out of the second sleeve 223 and the inner end is closed, which may include a second tube body 2221 and a second mounting seat 2222. In some embodiments, the inner end of the second tube body 2221 is open, and the second mounting seat 2222 is plugged into the inner end of the second tube body 2221 to close the inner end of the second tube body 2221. The second mounting seat 2222 can usually be made of a soft material to improve the sealing effect. The second mounting seat 2222 can be stepped, and the small end of the second mounting seat 2222 is plugged into the inner end of the second tube body 2221. The outer diameter of the large end of the second mounting seat 2222 is larger than the outer diameter of the inner end of the second tube body 2221, so that a positioning step is formed between the large end of the second mounting seat 2222 and the inner end of the second tube body 2221, and the inner side surface of the second sealing member 224 can be against the positioning step. In other embodiments, the second sealing member 224 may also be sleeved outside the large end of the second mounting seat 2222. In other embodiments, the inner end of the second tube 2221 may also be closed, and the second mounting seat 2222 may be sleeved on the inner end of the second tube 2221.

[0068] The second elastic member 225 may be sleeved outside the second inner tube 222. A second positioning platform 2224 may be provided outside the second inner tube 222 for the second elastic member 225 to abut against, and both ends of the second elastic member 225 abut against the second annular protrusion 2232 and the second positioning platform 2224, respectively. When the atomizer 1 and the host 2 are assembled, the second inner tube 222 is pushed to move from the third position to the fourth position, and the second elastic member 225 is compressed; when the atomizer 1 and the host 2 are detached from each other, the inward force on the second elastic member 225 disappears, and the second elastic member 225 is reset outward to the third position.

[0069] The outer rings of the outer ends of the first inner tube 122 and the second inner tube 222 may be provided with a third annular protrusion 1225 and a fourth annular protrusion 2225 along their radial directions respectively. The third annular protrusion 1225 abuts against the fourth annular protrusion 2225 to increase the contact area.

[0070] A third sealing member 126 may be provided between the outer wall of the first inner tube 122 and the inner wall of the first sleeve 123, and the two ends of the third sealing member 126 may respectively abut against the first positioning platform 1224 and the third annular protrusion 1225. A fourth sealing member 226 may be provided between the outer wall of the second inner tube 222 and the inner wall of the second sleeve 223, and the two ends of the fourth sealing member 226 may respectively abut against the second positioning platform 2224 and the fourth annular protrusion 2225. Both the third sealing member 126 and the fourth sealing member 226 may be made of soft materials to improve the sealing effect.

[0071] In some embodiments, the second liquid injection delivery module 22 may further include a fifth sealing member 227 disposed at the outer end of the second inner tube 222. The outer end inner ring of the second inner tube 222 extends radially outward to form a first mounting groove 2226, and the fifth sealing member 227 is mounted in the first mounting groove 2226. The fifth sealing member 227 is annular and the inner hole of the fifth sealing member 227 is connected to the inner hole of the second inner tube 222. The fifth sealing member 227 can generally be made of a soft material. After the first inner tube 122 and the second inner tube 222 are abutted and connected, the fifth sealing member 227 is easily compressed and deformed, thereby sealing the abutment between the first inner tube 122 and the second inner tube 222 to prevent leakage.

[0072] like Figure 3 , Figure 8 As shown, in some embodiments, the exhaust module 13 may include a third sleeve 133, a third inner tube 132, a sixth sealing member 134, and a third elastic member 135. The third inner tube 132 is axially movable and penetrates the third sleeve 133. The end of the third inner tube 132 opposite to the liquid storage chamber 11 is closed. An exhaust port 131 connected to the liquid storage chamber 11 is formed between the inner wall of the end of the third sleeve 133 opposite to the liquid storage chamber 11 and the outer wall of the third inner tube 132. An exhaust channel 136 is formed between the inner wall of the third sleeve 133 and the outer wall of the third inner tube 132. The liquid storage chamber 11 can be connected to the outside through the exhaust port 131 and the exhaust channel 136. The position of the exhaust port 131 can be higher than the first liquid inlet 121 to prevent leakage. The sixth sealing member 134 is matched at the exhaust port 131 to seal the exhaust port 131. The third elastic member 135 can be made of soft material to improve the sealing effect. The third elastic member 135 is connected to the third inner tube 132, and provides elastic force for the third inner tube 132 to return to its original position. When the third inner tube 132 is pressed into the liquid storage chamber 11, the sixth sealing member 134 is separated from the exhaust port 131, and the exhaust port 131 is connected to the liquid storage chamber 11. The liquid storage chamber 11 can be connected to the outside through the exhaust port 131 for exhaust. After the pressing force on the third inner tube 132 is removed, the third inner tube 132 moves outward and returns to its original position under the action of the third elastic member 135, and the exhaust port 131 is sealed.

To facilitate the installation of the third inner tube 132, the third inner tube 132 may include a third tube body and a third mounting seat plugged into one end of the third tube body in some embodiments.

[0074] Read also Figure 3 , 4 , 6, 8, 9, the electronic atomization device may further include a trigger module 23, a first driving module 24, and a second driving module 25 in some embodiments. The trigger module 23 is used to receive the trigger operation of the operator, and the first driving module 24 is connected to the liquid storage module 21 and the trigger module 23 respectively, so as to drive the liquid matrix in the liquid storage module 21 to inject liquid into the liquid storage chamber 11 through the second liquid injection transmission module 22 and the first liquid injection transmission module 12 under the control of the trigger module 23. The second driving module 25 is connected to the exhaust module 13 and the trigger module 23 respectively, so as to open the exhaust module 13 under the control of the trigger module 23 to exhaust the liquid storage chamber 11.

[0075] In some embodiments, the first driving module 24 may include a cylinder 241, a piston 242, a seventh sealing member 243, and a fourth elastic member 244. The cylinder 241 is connected to the liquid storage module 21, one end of the piston 242 is connected to the trigger module 23, and the other end is axially movable in the cylinder 241. The seventh sealing member 243 is arranged between the outer wall of the piston 242 and the inner wall of the cylinder 241 to prevent air leakage. The seventh sealing member 243 can be made of a soft material to improve the sealing effect. The fourth elastic member 244 is connected to the piston 242 to provide an elastic force for the piston 242 to reset. The outer ring of the piston 242 can be provided with a third positioning platform 2421 along its radial direction. The fourth elastic member 244 can be sleeved outside the piston 242, and one end thereof can be against the third positioning platform 2421, and the other end can be against the end surface of the cylinder 241 opposite to the trigger module 23. When the piston 242 is pressed into the cylinder 241, the piston 242 moves into the cylinder 241 to press the gas in the cylinder 241 into the liquid storage module 21 through the pipeline, and the liquid matrix in the liquid storage module 21 is injected into the liquid storage cavity 11 through the infusion pipeline, the second liquid injection transmission module 22, and the first liquid injection transmission module 12 by the action of gas pressure.

[0076] The trigger module 23 may be arranged on the atomizer 1 and / or the host 2, and it may be a button, a trigger button or a touch screen. When the trigger module 23 is a button, it may be a button, which is connected to the first drive module 24 and the second drive module 25 respectively, and controls the movement of the first drive module 24 and the second drive module 25. The first drive module 24 and the second drive module 25 may be triggered simultaneously or not at the same time under the pressing of the button. When the first drive module 24 and the second drive module 25 are not triggered at the same time, the pressing stroke of the button may include the first stroke and the second stroke, and when the button is pressed to the first stroke, the second drive module 25 is driven to open the exhaust module 13, and when it is continuously pressed to the second stroke, the first drive module 24 is driven to move, and the liquid storage chamber 11 is injected; or, when the button is pressed to the first stroke, the first drive module 24 is driven to move, and the liquid storage chamber 11 is injected, and when it is continuously pressed to the second stroke, the second drive module 25 is driven to open the exhaust module 13. In other embodiments, the trigger module 23 may also be two buttons, which are respectively connected to the first driving module 24 and the second driving module 25 to drive the movement of the first driving module 24 and the second driving module 25 .

[0077] When the trigger module 23 is a trigger button or a touch screen, the electronic atomization device may also include a control module 28. The trigger module 23 is electrically connected to the control module 28. The trigger module 23 receives the trigger instruction of the operator and transmits the trigger instruction to the control module 28. The control module 28 automatically drives the first drive module 24 and the second drive module 25 to move.

[0078] In this embodiment, the trigger module 23 is a button and the button can be set on the housing 26 of the host 2. The bottom of the button is connected to the piston 242, and the piston 242 is driven to move downward when the button is pressed; the side of the button is connected to the second driving module 25, and the second driving module 25 can be driven to move through the inclined plane transmission when the button is pressed.

[0079] In some embodiments, the second driving module 25 may include a driving rod 251 and a fifth elastic member 252. The two ends of the driving rod 251 are respectively in contact with the trigger module 23 and the exhaust module 13 to drive the exhaust module 13 to open under the control of the trigger module 23. The fifth elastic member 252 is connected to the driving rod 251 to provide an elastic force for the driving rod 251 to reset. The driving rod 251 may be stepped, and may include a first rod segment 2511 connected to the trigger module 23 and having a larger diameter, and a second rod segment 2512 connected to the exhaust module 13 and having a smaller diameter, with a step formed between the first rod segment 2511 and the second rod segment 2512. The fifth elastic member 252 may be sleeved outside the second rod segment 2512, and the two ends of the fifth elastic member 252 may be respectively in contact with the step and the housing 26. The contact surface between the first rod section 2511 and the trigger module 23 is an inclined surface. When the button is pressed, the driving rod 251 can be driven to move horizontally through the inclined surface, thereby pushing the third inner tube 132 to move into the liquid storage chamber 11 to open the exhaust port 131.

[0080] The liquid injection process of the electronic atomization device is as follows: after pressing the button, the driving rod 251 is driven to move horizontally through the inclined transmission, thereby pushing the third inner tube 132 to move into the liquid storage chamber 11 and opening the exhaust port 131; continue to press the button, the button pushes the piston 242 to move downward to press the gas in the cylinder 241 into the liquid storage module 21 through the pipeline, and the liquid matrix in the liquid storage module 21 is injected into the liquid storage chamber 11 through the infusion pipeline, the second liquid injection transmission module 22, and the first liquid injection transmission module 12 through the action of air pressure, and the gas in the liquid storage chamber 11 is discharged through the exhaust module 13 to balance the air pressure inside and outside the liquid storage chamber 11, so that the liquid matrix will not be unable to be injected into the liquid storage chamber 11 due to air pressure problems. After the button is released, the third inner tube 132 moves to the outside of the liquid storage chamber 11 and resets under the action of the third elastic member 135, closing the exhaust port 131; the piston 242 moves upward and resets under the action of the fourth elastic member 244, sucking the gas in the liquid storage module 21 into the cylinder 241, and returning the gas (and a small amount of liquid matrix) in the liquid storage chamber 11 to the liquid storage module 21 through the first liquid injection transmission module 12, the second liquid injection transmission module 22, and the infusion pipeline. Due to the negative pressure of the back suction, the piston 242 and the button will rebound slowly.

[0081] After the atomizer 1 and the host 2 are assembled, the first liquid injection transmission module 12 and the second liquid injection transmission module 22 are both in a conducting state. When the liquid matrix in the liquid storage chamber 11 is higher than the first liquid inlet 121, the liquid matrix in the liquid storage chamber 11 will flow back into the liquid storage module 21 through the first liquid injection transmission module 12, the second liquid injection transmission module 22, and the infusion pipeline, thereby limiting the liquid matrix in the liquid storage chamber 11 to a certain capacity range.

The liquid storage module 21a may generally be a liquid storage bottle and may be installed at the bottom of the housing 26a. The second liquid injection transmission module 22a may be arranged on the housing 26a and correspondingly arranged with the first liquid injection transmission module 12a, and may interact and conduct with the first liquid injection transmission module 12a under the action of external force, so as to connect the liquid storage chamber 11a with the liquid storage module 21a. Preferably, the second liquid injection transmission module 22a is located higher than the liquid storage module 21a.

[0087] In some embodiments, a first one-way valve 211a is further provided between the second liquid injection delivery module 22a and the liquid storage module 21a. The inlet of the first one-way valve 211a is connected to the liquid storage module 21a, and the outlet is connected to the second liquid injection delivery module 22a, so that the liquid matrix and air can only flow from the liquid storage module 21a to the second liquid injection delivery module 22a in one direction. In some embodiments, the first one-way valve 211a can be provided at the bottle mouth of the liquid storage module 21a.

The eighth sealing member 124a and the ninth sealing member 125a can usually be made of soft materials to improve the sealing effect. The seventh elastic member 126a is connected to the fourth inner tube 122a to provide elastic force for the fourth inner tube 122a to reset.

[0089] In some embodiments, the second liquid injection transmission module 22a may include a fifth inner tube 222a and a sixth elastic member 223a. The inner hole of the fifth inner tube 222a is respectively connected to the inner hole of the fourth inner tube 122a and the liquid storage module 21a, and the fifth inner tube 222a can move back and forth between the fifth position and the sixth position relative to the outer shell 26a; when the fifth inner tube 222a is located at the fifth position, the fifth inner tube 222a exerts a downward force on the fourth inner tube 122a, pushing the fourth inner tube 122a to move into the liquid storage chamber 11a, so that the eighth sealing member 124a is away from the fourth opening 1231a, and the first liquid inlet When the fifth inner tube 222a is at the sixth position, the force exerted by the fifth inner tube 222a on the fourth inner tube 122a is removed, and the fourth inner tube 122a moves and resets under the action of the seventh elastic member 126a, so that the first liquid inlet 121a is isolated from the liquid storage chamber 11a, and the exhaust port 127a is sealed. The sixth elastic member 223a is connected to the fifth inner tube 222a, and provides an elastic force for the fifth inner tube 222a to reset, so as to elastically maintain the fifth inner tube 222a at the sixth position.

[0090] In some embodiments, the second liquid injection transmission module 22a may further include a connecting pipe 221a and a base 224a. The base 224a may be fixedly mounted on the housing 26a, and the fifth inner tube 222a may be axially movably arranged in the base 224a and its two ends extend out of the base 224a. The outer ring of the end of the fifth inner tube 222a opposite to the fourth inner tube 122a may be provided with an eighth annular protrusion 2221a along its radial direction to prevent the fifth inner tube 222a from escaping from the base 224a. The connecting pipe 221a connects the fifth inner tube 222a with the liquid storage module 21a.

[0091] In some embodiments, the inner circle of the end of the fourth sleeve 123a opposite to the liquid storage chamber 11a is provided with a ninth annular protrusion 1232a along its radial direction, and the inner hole of the ninth annular protrusion 1232a forms a fourth opening 1231a. The eighth sealing member 124a can be sealed with the inner side surface (the side surface opposite to the liquid storage chamber 11a) of the ninth annular protrusion 1232a to prevent leakage.

[0092] The end (inner end) of the fourth inner tube 122a opposite to the liquid storage chamber 11a can extend out of the fourth sleeve 123a and the inner end is closed, which may include a fourth tube body 1221a and a fourth mounting seat 1222a.

When injecting liquid, it is convenient to insert the fifth inner tube 222a into the sleeve tube section 1224a first, and the step difference between the two can be used to facilitate pressing and applying force to the fourth inner tube 122a.

[0094] A bell-shaped guide portion 1223a may be provided between the sleeve tube section 1224a and the fourth tube body 1221a, and the large end of the guide portion 1223a is connected to the sleeve tube section 1224a, and the small end of the guide portion 1223a is connected to the fourth inner tube 122a.

[0097] like Figure 12-15 As shown, the electronic atomization device may further include a trigger module 23a, a first driving module 24a, and a second driving module 25a in some embodiments. The trigger module 23a is used to receive a trigger operation of the operator, and the first driving module 24a is connected to the liquid storage module 21a and the trigger module 23a respectively, so as to drive the liquid matrix in the liquid storage module 21a to inject liquid into the liquid storage chamber 11a through the second liquid injection transmission module 22a and the first liquid injection transmission module 12a under the control of the trigger module 23a.

[0098] In some embodiments, the first driving module 24a may include a cylinder 241a, a piston 242a, a seventh sealing member 243a, and a fourth elastic member 244a. The cylinder 241a is connected to the liquid storage module 21a, one end of the piston 242a is connected to the trigger module 23a, and the other end is axially movable in the cylinder 241a. The seventh sealing member 243a is arranged between the outer wall of the piston 242a and the inner wall of the cylinder 241a to prevent air leakage. The seventh sealing member 243a can be made of soft material to improve the sealing effect. The fourth elastic member 244a is connected to the piston 242a to provide an elastic force for the piston 242a to reset. The outer ring of the piston 242a can be provided with a third positioning platform 2421a along its radial direction. The fourth elastic member 244a can be sleeved outside the piston 242a, and one end thereof can abut against the third positioning platform 2421a, and the other end can abut against the end surface of the cylinder 241a opposite to the trigger module 23a. When the piston 242a is pressed into the cylinder 241a, the piston 242a moves into the cylinder 241a to press the gas in the cylinder 241a into the liquid storage module 21a through the pipeline 246a, and the liquid matrix in the liquid storage module 21a is injected into the liquid storage chamber 11a through the liquid infusion pipeline, the second liquid injection transmission module 22a, and the first liquid injection transmission module 12a by the gas pressure. A second one-way valve 245a connected to the external air can also be provided on the cylinder 241a. The inlet of the second one-way valve 245a is connected to the cylinder 241a, and the outlet is connected to the external air, so that the external air can only flow into the cylinder 241a through the second one-way valve 245a, and the gas in the cylinder 241a will not flow out through the second one-way valve 245a. In the untriggered state, the first one-way valve 211a and the second one-way valve 245a are in a natural closed state, so that the liquid storage module 21a and the cylinder 241a form a relatively closed state, thereby preventing leakage.

[0099] The second driving module 25a is connected to the second liquid injection transmission module 22a and the trigger module 23a respectively, so as to drive the second liquid injection transmission module 22a to communicate with the first liquid injection transmission module 12a under the control of the trigger module 23a, and open the first liquid injection port 121a and the exhaust port 127a to inject liquid into and exhaust the liquid storage chamber 11a. In some embodiments, the second driving module 25a can be a rotating block, which can be rotatably mounted on the housing 26a through the rotating shaft 251a. The second driving module 25a is in contact with the connecting tube 221a, and the contact surface between the second driving module 25a and the connecting tube 221a can be an inclined surface. When the second driving module 25a rotates downward, the connecting tube 221a is pushed downward by the inclined surface transmission; when the connecting tube 221a moves upward and resets under the action of the sixth elastic member 223a, the second driving module 25a is pushed upward and reset by the inclined surface transmission.

[0100] The trigger module 23a can be arranged on the atomizer 1a and / or the mainframe 2a, and it can be a button, a trigger button or a touch screen. When the trigger module 23a is a button, it can be a button, and the button is connected with the first drive module 24a and the second drive module 25a respectively, and controls the motion of the first drive module 24a and the second drive module 25a. The first drive module 24a and the second drive module 25a can be triggered simultaneously or not triggered at the same time under the pressing of the button. When the first drive module 24a and the second drive module 25a are not triggered at the same time, the pressing stroke of the button may include the first stroke and the second stroke, and when the button is pressed to the first stroke, the second drive module 25a is driven to open the first liquid injection port 121a and the exhaust port 127a, and when the second stroke is continued to be pressed, the first drive module 24a is driven to move, and the liquid storage chamber 11a is injected. In other embodiments, the trigger module 23a may also be two buttons, which are respectively connected to the first driving module 24a and the second driving module 25a to drive the movement of the first driving module 24a and the second driving module 25a.

[0101] When the trigger module 23a is a trigger button or a touch screen, the electronic atomization device may also include a control module 28a. The trigger module 23a is electrically connected to the control module 28a. The trigger module 23a receives the trigger instruction of the operator and transmits the trigger instruction to the control module 28a. The control module 28a automatically drives the first drive module 24a and the second drive module 25a to move.

[0102] In this embodiment, the trigger module 23a is a button and the button can be set on the housing 26a of the host 2a. The bottom of the button is fixedly connected to the piston 242a, and the piston 242a is driven to move downward when the button is pressed; one side of the bottom of the button is in contact with the second driving module 25a, and the second driving module 25a can be driven to rotate downward when the button is pressed, thereby pushing the connecting tube 221a to move downward.

[0103] The liquid injection process of the electronic atomization device is as follows: after the button is pressed, the second driving module 25a is driven to rotate downward, thereby pushing the connecting tube 221a and the fifth inner tube 222a to move downward, and the fifth inner tube 222a moves to abut against the fourth inner tube 122a, and then pushes the fourth inner tube 122a to move into the liquid storage chamber 11a, so that the fifth inner tube 222a is connected with the fourth inner tube 122a, and the first liquid inlet 121a and the exhaust port 127a are opened; continue to press the button, and the button pushes the piston 242a moves downward to press the gas in the cylinder 241a into the liquid storage module 21a through the pipe 246a, and the liquid matrix in the liquid storage module 21a is injected into the liquid storage chamber 11a through the infusion pipe, the second liquid injection transmission module 22a, and the first liquid injection transmission module 12a by the air pressure. The gas in the liquid storage chamber 11a is discharged through the exhaust port 127a to balance the air pressure inside and outside the liquid storage chamber 11a, and the liquid matrix will not be unable to be injected into the liquid storage chamber 11a due to the problem of air pressure.

[0104] After releasing the button, the piston 242a and the button move upward and reset under the action of the fourth elastic member 244a, and the external air is sucked into the cylinder 241a through the second one-way valve 245a. At the same time, due to the action of the first one-way valve 211a, a vacuum state is formed in the liquid storage module 21a, and when the cylinder 241a sucks back the air, it is ensured that the gas and liquid matrix in the liquid storage module 21a will not be sucked into the cylinder 241a. While the button is returning to its original position, the fifth inner tube 222a and the connecting tube 221a move upward and reset under the action of the sixth elastic member 223a, pushing the second driving module 25a to rotate upward and reset, and isolating the fifth inner tube 222a from the fourth inner tube 122a; the fourth inner tube 122a moves upward and reset under the action of the seventh elastic member 126a, closing the first liquid inlet 121a and the exhaust port 127a to prevent leakage.

[0105] The electronic atomization device in the present invention can inject liquid into the liquid storage chamber of the atomizer at any time through the liquid storage module arranged in the main unit to replenish the liquid matrix, so there is no need to carry a liquid storage bottle separately; the liquid injection operation is simple, and after pressing the button, the liquid matrix in the liquid storage module can be driven by the action of air to inject liquid into the liquid storage chamber through the second liquid injection transmission module and the first liquid injection transmission module, and it is not easy to dirty the operator's hands.

[0106] It can be understood that the above-mentioned technical features can be used in any combination without limitation.

[0107] The above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention.
