When the air regulating member 400 is in the first position, the two air regulating holes 421 do not overlap with the air inlet hole, the sliding button 341 of the toggle switch 340 is in the closed position, and the main control board 330 controls the first heating wire 260 and the second heating wire 270 of the double heating wire according to the first electrical signal sent by the toggle switch 340 at this time to stop heating; when the air regulating member 400 is in the second position, the single air regulating hole 421 overlaps with the single air inlet hole, and the air in the external space enters the housing 100 through the connected single air regulating hole 421 and the air inlet hole in turn. At this time, the air intake volume is small, and the sliding button 341 of the toggle switch 340 is in the first gear open position, and the main control board 330 controls the first heating wire 260 and the second heating wire 270 of the double heating wire to stop heating; when the air regulating member 400 is in the second position, the single air regulating hole 421 overlaps with the single air inlet hole, and the air in the external space enters the housing 100 through the connected single air regulating hole 421 and the air inlet hole in turn. At this time, the air intake volume is small, and the sliding button 341 of the toggle switch 340 is in the first gear open position, and the main control board 330 The board 330 controls the first heating wire 260 and the second heating wire 270 of the double heating wire to alternately heat up according to the first electrical signal sent by the toggle switch 340 at this time; when the air regulating component 400 is located at the third position, the two air regulating holes 421 coincide with the two air inlet holes respectively, and the air from the outside space enters the shell 100 through the two connected air regulating holes 421 and the air inlet holes in turn. At this time, the air intake volume is large, and the sliding button 341 of the toggle switch 340 is in the second gear open position. The main control board 330 controls the first heating wire 260 and the second heating wire 270 of the double heating wire to heat up together according to the first electrical signal sent by the toggle switch 340 at this time.

[0069] In one embodiment, the dual heating wire atomization device 1 also includes a suction nozzle 600 and a mist outlet pipe 700. The suction nozzle 600 is installed on one end of the shell 100 away from the power supply device 300. The mist outlet pipe 700 is installed in the atomization device 200, and one end of the mist outlet pipe 700 is connected to the suction nozzle 600, and the other end of the mist outlet pipe 700 is connected to the atomization tube 240. The aerosol generated by heating the liquid matrix in the atomization tube 240 by the first heating wire 260 and the second heating wire 270 reaches the suction nozzle 600 through the atomization tube 240 and the mist outlet pipe 700 for the user to inhale.

[0070] In one embodiment, the atomization device 200 includes an upper sealing cover 210, a liquid storage cup 220 and a lower sealing cover 230. The upper sealing cover 210, the liquid storage cup 220 and the lower sealing cover 230 enclose a storage space of the atomization device 200. The atomization tube 240 is arranged in the storage space. The oil storage chamber 201 is arranged in the storage space and is located on the outside of the atomization tube 240.

The inner side of the upper sealing cover 210 is provided with a liquid absorption groove (not shown in the figure), and the oil absorption cotton 203 and the partition 204 are installed in the liquid absorption groove from top to bottom. The mist outlet pipe 700 passes through the partition 204 and the oil absorption cotton 203 in sequence and then connects with the suction nozzle 600.

[0071] It is easy to understand that the aerosol generated by the atomized liquid matrix is ​​easily condensed in the atomizing tube 240 to form condensate. When the aerosol mixed with condensate reaches the connection position between the mist outlet pipe 700 and the suction nozzle 600, the condensate can be absorbed by the oil-absorbing cotton 203 and the partition 204 blocks the condensate absorbed on the oil-absorbing cotton 203 from returning to the oil storage chamber 201 again, thereby reducing or even eliminating the possibility of the condensate being inhaled by the user.

[0072] In one embodiment, the lower sealing cover 230 is arranged at the bottom of the oil storage chamber 201 to seal the oil storage chamber 201, and the atomizer tube 240 is plugged and installed on the lower sealing cover 230. The lower sealing cover 230 is provided with a penetrating air intake hole 231 and a pin through hole 232, and the air intake hole 231 is arranged corresponding to the atomizer tube 240, so that the gas entering the shell 100 from the external space through the air regulating hole 421 and the air intake hole can enter the atomizer tube 240 after passing through the air intake hole 231, so that the aerosol generated by the liquid matrix in the atomizer tube 240 can be carried to the suction nozzle 600 for the user to inhale.

It should be noted that in the present embodiment, the first, second and third electrical connection holes 233, 234 and 235 are all configured as blind holes to prevent the first, second and third electrodes 510, 520 and 530 from penetrating the lower sealing cover 230.

The first electrode 510, the second electrode 520 and the third electrode 530 are respectively welded to the main control board 330 after passing through the first mounting hole 311, the second mounting hole 312 and the third mounting hole 313 to achieve electrical connection with the main control board 330.

[0074] In one embodiment, the atomizer assembly further includes a mounting seat 290, and the mounting seat 290 is mounted on the air inlet hole 231. It is easy to understand that since the air inlet hole 231 is provided on the lower sealing cover 230, and the atomizer tube 240 is plugged and installed on the lower sealing cover 230, and the oil-conducting cotton 250 is provided in the atomizer tube 240, the oil-conducting cotton 250 is also located above the mounting seat 290, and one end of the mounting seat 290 close to the oil-conducting cotton 250 is provided as a truncated cone-shaped inclined surface, and the atomizer tube 240 is plugged between the outer side surface of the mounting seat 290 and the inner wall of the air inlet hole 231. A plurality of racks are evenly spaced on the outer side surface of the mounting seat 290 around the central axis of the mounting seat 290, and a tooth groove is formed between any two racks of the mounting seat 290, and the first pin 261, the second pin 262 and the third pin 271 extend into the pin inlet hole 232 after passing through the tooth groove.

[0075] It is easy to understand that because the tooth groove is narrow and the first pin 261, the second pin 262 and the third pin 271 are arranged in the tooth groove, the first pin 261, the second pin 262 and the third pin 271 can be stably and reliably fixed between the mounting base 290 and the inner wall of the atomizer tube 240 to ensure that the circuit where the first pin 261, the second pin 262 and the third pin 271 are located is stable and reliable.

[0076] In one embodiment, the air intake hole 231 is in the shape of a circular countersunk hole, and the air intake hole 231 includes a connected large diameter section and a small diameter section. The mounting seat 290 is installed in the large diameter section, and the pin through-hole 232 penetrates from the bottom surface of the large diameter section to the surface of the lower sealing cover 230, so that the first pin 261, the second pin 262 and the third pin 271 can pass through the lower sealing cover 230 from the air intake hole 231; the pin through-hole 232 is in the shape of an arc, and the first electrical connection hole 233, the second electrical connection hole 234 and the third electrical connection hole 235 are arranged on the lower sealing cover 230 on the side of the pin through-hole 232 away from the air intake hole 231.

[0077] It is easy to understand that by installing the mounting seat 290 in the large diameter section of the air inlet through hole 231, and making the pin through hole 232 penetrate from the bottom surface of the large diameter section to the surface of the lower sealing cover 230, it is convenient for the first pin 261, the second pin 262 and the third pin 271 to enter the pin through hole 232 after passing through the tooth groove of the mounting seat 290, and setting the pin through hole 232 in an arc shape can facilitate the first pin 261, the second pin 262 and the third pin 271 to pass through, avoiding the straight-line pin through hole that easily causes the first pin 261, the second pin 262 and the third pin 271 to pass through. The undesirable phenomenon that the pin 261, the second pin 262 and the third pin 271 are stacked and crowded and cannot pass through the pin through-hole 232 occurs; the first electrical connection hole 233, the second electrical connection hole 234 and the third electrical connection hole 235 are all arranged on the side of the lower sealing cover 230 away from the air inlet hole 231 can facilitate the first pin 261, the second pin 262 and the third pin 271 to be bent and inserted into the first electrical connection hole 233, the second electrical connection hole 234 and the third electrical connection hole 235 after passing through the pin through-hole 232.

More specifically, at least one side of the fixing protrusion 111 is provided with a guide inclined surface (not shown in the figure), and at least one side of the inner wall of the fixing groove 121 is provided with a guide inner wall (not shown in the figure).
