[0036] See also Figure 1 to Figure 7 , the electronic cigarette provided in this embodiment is now described. The electronic cigarette 100 in this embodiment includes a shell 11, an atomizer 1, a main control unit 2 and an oil bottle 3. The atomizer 1 has an oil storage chamber 131. The oil storage chamber 131 has a visualization area, and the user can observe the remaining amount of tobacco oil in the oil storage chamber 131 in real time. An atomization module 12 is fixedly installed in the oil storage chamber 131. The oil storage chamber 131 is located on the outside of the atomization module 12 and can accommodate tobacco oil. An air outlet channel 14 is formed inside the atomization module 12. As a main component of the atomizer 1, the atomization module 12 is used to heat the atomized tobacco oil to form smoke, and the smoke overflows through the air outlet channel 14 for human inhalation. One end of the shell 11 has an opening, and a mounting seat 16 is provided in the shell 11. The atomizer 1 is fixed on the mounting seat 16 and part of the atomizer 1 extends out through the opening. The part of the atomizer 1 that extends out of the opening can be configured as a mouthpiece 13. The cross section of the mouthpiece 13 is oval, which is ergonomic and improves the comfort of inhalation. The main control unit 2 and the oil bottle 3 are arranged side by side at the end of the electronic cigarette 100 away from the atomizer 1. An air inlet 115 is provided on one side of the housing 11. The mounting seat 16 is provided with an air inlet channel 163, and the air inlet channel 163 connects the air inlet 115 and the atomizer 1. The mounting seat 16 is located at the end of the air inlet channel 163 away from the atomizer 1 and is provided with a first drainage channel 162 in the direction toward the main control unit 2. The end of the main control unit 2 close to the atomization module 12 is provided with a second drainage channel 27. An airflow sensor 25 is provided in the second drainage channel 27, and the airflow sensor 25 is electrically connected to the main control unit 2.

[0037] Specifically, Figure 4As shown, the atomizer 1 is fixed in the middle of the mounting seat 16, the air inlet 115 is provided on one side of the housing 11, the air inlet channel 163 extends from one end of the air inlet 115 along the lateral direction of the mounting seat 16 to the atomizer 1, and the first drainage channel 162 extends from one side of the air inlet 115 along the longitudinal direction of the mounting seat 16 to the mating surface 281 of the main control unit 2 and the housing 11. The main control unit 2 is provided with a second drainage channel 27 at one end corresponding to the atomization module 12, and the air flow sensor 25 is installed in the second drainage channel 27. When the electronic cigarette 100 is in the suction state, air flows into the mounting seat 16 through the air inlet 115, and the mounting seat 16 has an air inlet channel 163. The gas enters the atomizer 1 from the air inlet channel 163. Since the first drainage channel 162 is connected to the air inlet 115, part of the air flow can enter the second drainage channel 27 through the first drainage channel 162, and the air flow sensor 25 detects the change of air flow in the drainage channel to start working. Compared with the air inlet 115 being arranged at the bottom of the electronic cigarette 100, this design can shorten the length of the airway, thereby improving the sensitivity of the airflow sensor 25. The airflow sensor 25 can quickly detect the airflow change and start the electronic cigarette 100. In addition, no other components are arranged in the drainage channel, and the suction resistance is small, achieving a better suction effect. It should be noted that the longitudinal direction described here refers to the height direction of the mounting base 16, and the transverse direction refers to the height direction perpendicular to the mounting base 16.

[0038] Furthermore, the cross-sectional area of ​​the first drainage channel 162 and the cross-sectional area of ​​the second drainage channel 27 are both smaller than the cross-sectional area of ​​the air inlet channel 163. In this way, the gas capacity of the first drainage channel 162 and the second drainage channel 27 is relatively small. That is, even if the gas in the first drainage channel 162 undergoes a slight change, the airflow sensor 25 can detect it immediately, thereby improving the monitoring sensitivity.

[0039] In one possible embodiment, see Figures 4 to 6 The second drainage channel 27 is embedded with a sealing ring 29, and part of the sealing ring 29 protrudes from the end surface of the second drainage channel 27. The mounting seat 16 is provided with an annular groove (not shown) at the end of the first drainage channel 162. When the main control unit 2 is assembled on the housing 11, the sealing ring 29 protruding from the second drainage channel 27 is embedded in the annular groove. Since the sealing ring 29 has good deformation ability, it fills the matching gap between the two drainage channels, thereby forming a good seal and preventing the gas in the drainage channel from overflowing.

[0040] In one possible embodiment, see 4 and Figure 7, the mounting seat 16 is provided with a groove 15 on one side of the atomizing module 12, and the mounting seat 16 is provided with a through groove (not shown) from one side of the groove 15 to the direction of the air inlet 115, and the through groove and part of the groove 15 are enclosed to form an air inlet channel 163. A groove 15 is provided below the air inlet channel 163 of the atomizing module 12 where the mounting seat 16 is located, which reduces the contact area of ​​the mounting seat 16 with the atomizing module 12, and is conducive to the gas passing through the mounting seat 16 to quickly enter the atomizing module 12. Among them, the mounting seat 16 is located in the groove 15 and is protruding with a baffle 151. The baffle 151 and the side wall of part of the groove 15 are enclosed to form a liquid storage tank, which is located below the air outlet channel 14 of the atomizer 1. The condensate formed by the cooling of the smoke can flow into the liquid storage tank to avoid the condensate from overflowing, thereby improving the user experience. Preferably, a liquid storage cotton 152 is provided in the liquid storage tank. The liquid storage cotton 152 has good oil locking and oil absorption capabilities.

[0041] In one possible embodiment, Figure 5 As shown, the main control unit 2 includes a main control board 22 and a battery 21. The battery 21 provides power for the atomizer 1, and the main control board 22 is used to control the working condition of the atomizer 1. The main control unit 2 and the atomizer 1 are matched in a detachable manner, such as the main control unit 2 is fixed to the atomizer 1 by snaps, threads, adhesives, or magnetic suction. Correspondingly, the oil bottle 3 can also be fixed to the atomizer 1 in a detachable manner. The atomizer 1 is provided with an oil inlet channel 161 connecting the oil storage chamber 131 and the oil bottle 3. The oil inlet channel 161 is provided with an oil sealing structure 6. The oil sealing structure 6 is similar to a valve and is used to control whether the oil inlet channel 161 is conductive or not. The oil storage capacity of the oil bottle 3 is much larger than the oil storage capacity of the oil storage chamber 131 in the housing 11. When the smoke oil in the oil storage chamber 131 is exhausted, the smoke oil in the oil bottle 3 can replenish the oil storage chamber 131 in time.

[0042] In this embodiment, the electronic cigarette 100 is divided into three parts, namely, the atomizer 1, the main control unit 2 and the oil bottle 3, according to the functional modules. The functional components can be assembled in the first assembly step, and then the assembled functional modules are spliced ​​to form a smoke generator, which simplifies the assembly process and reduces the complexity of the assembly procedure. The oil bottle 3 and the main control unit 2 are respectively fixed to the end of the housing 11 away from the atomizer 1 in a detachable manner. When disassembling and assembling, the oil bottle 3 and the main control unit 2 are unobstructed and can be quickly disassembled and assembled. In addition, each functional module is independent of each other, and classified recycling is achieved to meet environmental protection requirements. In addition, the oil bottle 3 is equivalent to the second oil reservoir of the electronic cigarette 100. A large amount of smoke oil stored in the oil bottle 3 can be replenished to the oil storage chamber 131 in time to meet the user's requirements for large capacity.

[0043] In one possible embodiment, see Figure 2 and Figure 6A first accommodating chamber 111 and a second accommodating chamber 112 are provided at one end of the housing 11 away from the atomizer 1, and the main control unit 2 and the oil bottle 3 are placed in the first accommodating chamber 111 and the second accommodating chamber 112 respectively.

[0044] The first accommodating cavity 111 is provided with a first retaining member 171, and correspondingly, the side wall of the main control unit 2 is provided with a second retaining member 26 adapted to the first retaining member 171. The two retaining members cooperate with each other to generate a force so that the component is fixed in a certain position. Preferably, the retaining member is a magnet, and due to the magnetic attraction of the magnet, the main control unit 2 is fixed in the first accommodating cavity 111. The main control unit 2 is fixed to the housing 11 using a magnet, and the fixing method is simple and convenient for disassembly.

[0045] The cartridge-changing electronic cigarette 100 includes a cartridge and a cigarette rod. The cartridge and the cigarette rod are usually adapted up and down, the rod is slender, and the holding experience is not good. In addition, there is no oil storage cotton in the cartridge, and the risk of oil leakage is high. Therefore, the oil capacity of the cartridge is usually about 2ml, the oil capacity is small, and the experience is poor. In this embodiment, the oil bottle 3 and the main control unit 2 are arranged side by side on the shell 11, which is short in length, easy to carry, and has strong mechanical strength. In addition, the diameter of the device is larger, which increases the fun of sucking and holding, and is more suitable for meeting the psychological needs of large-caliber users. And the oil bottle 3 and the main control unit 2 are exposed outside the shell 11 in a detachable manner, and the two structures can be quickly removed from the shell 11, thereby improving the disassembly and assembly efficiency, and each component can be quickly recovered. The atomization module 12 is arranged in the shell 11, and the shell 11 is a hard shell structure that is not easy to break under the action of external force. And adding the oil bottle 3 to the atomizer 1 can replenish the oil in time, overcoming the problem of small oil capacity of the cartridge-changing electronic cigarette 100.

[0046] like Figure 2 As shown, the main control unit 2 is generally a rectangular parallelepiped. When the main control unit 2 is limited to the first accommodating cavity 111, the upper and lower end surfaces of the main control unit 2 and a side wall that abuts against the first accommodating cavity 111 are called matching surfaces 281, and the other three side surfaces are exposed to the outside of the housing 11, which are non-matching surfaces 282. The main control unit 2 includes a housing 28, a main control board 22, a battery 21 and a display screen 23. The main control board 22 and the battery 21 are respectively arranged in the housing 28. The main control board 22 is located below the airflow sensor 25, and the display screen 23 is fixed on the outer wall of the housing 28. The display screen 23 is an interface for human-computer interaction. The user can control the working condition of the electronic cigarette 100 and display various parameters of the device through the display screen 23. The display screen 23 can be a flexible curved screen, which is configured on the non-matching surface 282 of the main control unit 2, thereby satisfying consumers' pursuit of large screens. The large-area display screen 23 makes the displayed data more vivid and intuitive. Of course, the size and number of the display screens 23 can be set according to actual conditions, and the display screens 23 can be distributed on one or more side walls of the main control unit 2.

[0047] The smoke device also includes a fingerprint module (not shown), which is integrated into the display screen 23 to prevent children from accidentally starting it. A USB interface 24 is provided at the bottom of the main control unit 2, which integrates charging and discharging and data transmission functions. The main control unit 2 is completely independent of the atomizer 1. When the main control unit 2 is removed, it can be used as a mobile power source.

[0048] In one possible implementation, the oil bottle 3 is configured as an oil reservoir in the electronic cigarette 100, which can be used to store different flavors of oil to meet the user's pursuit of various tastes. The oil bottle 3 is cylindrical, generally white, and can store 7 ml of oil. The oil storage chamber 131 can be filled with oil in time, which solves the problem that the electronic cigarette 100 needs to use professional tools for oil filling or needs to carry extra oil. The oil bottle 3 can be made of transparent or plate-transparent plastic, tempered film or glass. Correspondingly, the area of ​​the shell 11 located in the oil storage chamber 131 is at least partially made transparent, so that the user can observe the remaining oil in the oil storage chamber 131 in time and replenish the oil in the oil storage chamber 131 in time.

[0049] A side cover 4 is provided on the side of the housing 11 away from the main control unit 2. The side cover 4 can be fixed to the housing 11 by means of magnetism, snapping, or hinges. The side cover 4 and the housing 11 enclose a second accommodating cavity 112, and the second accommodating cavity 112 accommodates the oil bottle 3. The side cover 4 is provided on the outer peripheral side of the oil bottle 3 to effectively prevent damage to the oil bottle 3 due to a collision. The side cover 4 can be made of transparent, translucent, or opaque materials. When the side cover 4 is formed of an opaque material, a plurality of hollow holes 41 are provided on the side cover 4 at intervals to allow the user to observe the remaining oil in the oil bottle 3 through the hollow holes 41.

[0050] Preferably, at least one side of the side cover 4 is movably connected to the outer shell 11, so that the side cover 4 is not easy to slide off the outer shell 11, and the stability of the two structures is ensured. The side cover 4 can be rotated relative to the outer shell 11. When replacing the oil bottle 3, the side cover 4 is rotated so that the outer side of the oil bottle 3 is not blocked, which is convenient for disassembly and assembly of the oil bottle 3. Specifically, an insertion strip 42 extends from one end of the side cover 4 close to the far end of the outer shell 11, and a sliding groove 116 is provided on one side of the outer shell 11. The sliding groove 116 is provided with a plurality of insertion holes 117 that cooperate with the insertion strip 42, and the plurality of insertion holes 117 are spaced apart along the height direction of the sliding groove 116. When the oil bottle 3 needs to be disassembled, the side cover 4 is pulled down and then rotated toward the direction of the atomizer 1, so that the oil bottle 3 is completely exposed to the outer shell 11.

[0051] Furthermore, a first magnetic member 43 is provided at one end of the side cover 4 located on the oil bottle 3 away from the oil inlet channel 161, and a second magnetic member 172 is provided at the bottom of the second accommodating cavity 112. When the side cover 4 is in the closed state, the polarities of the two magnetic members are opposite, and a magnetic attraction effect can occur, so that the side cover 4 is not easy to slide off the housing 11.

[0052] In a possible embodiment, the electronic cigarette 100 further includes an air-adjusting structure 5, which includes a silica gel 51 and an air-adjusting switch 52. The silica gel 51 is embedded in the air inlet 115, and the air-adjusting switch 52 is slidably installed in the air inlet 115. The slidable air-adjusting switch 52 controls the shielding area of ​​the air inlet 115 to control the air intake volume, thereby achieving the purpose of controlling the amount of smoke. Specifically, the air inlet 115 is provided on the outer peripheral side of the housing 11 close to the main control unit 2, and the overall air circuit is shorter, so that the airflow sensor 25 can detect the change of the airflow faster, thereby quickly starting the atomizer 1 to work, and the smoke output efficiency is faster.

[0053] In a possible embodiment, the mounting seat 16 is provided with a mounting groove 164 at the position of the oil bottle 3, and the mounting groove 164 is provided with an internal thread (not shown), and the oil bottle 3 is correspondingly provided with an external thread 33 that matches the internal thread. The oil bottle 3 is fixed to the mounting seat 16 through thread matching. The oil bottle 3 is fixed to the housing 11 by thread fixing, and the thread connection can well withstand tension and vibration, avoiding the problem of loosening due to interference from other external forces and causing leakage of the smoke oil.

[0054] The oil bottle 3 includes an oil bottle body 31 and an upper connecting portion 32 provided on the oil bottle body 31, and an outer thread 33 adapted to the inner thread is provided on the outer peripheral side of the connecting portion 32. The outer diameter of the connecting portion 32 is much smaller than the outer diameter of the oil bottle body 31. A positioning groove for accommodating the liquid outlet is provided at the bottom of the mounting groove 164 in the direction of the atomization module 12, and the mounting seat 16 extends an oil inlet channel 161 from the bottom end of the positioning groove to the atomizer 1. The oil inlet channel 161 is a straight cylinder. Compared with the circuitous oil inlet line, the oil inlet channel 161 has a shorter path, which is conducive to quickly transporting the smoke oil in the oil bottle 3 to the oil storage chamber 131. A slot (not shown) is transversely provided on the outer wall of the mounting seat 16 corresponding to the position of the oil inlet channel 161, and the slot is connected to the oil inlet channel 161. The oil sealing structure 6 is embedded in the slot, and the oil sealing structure 6 can block or open the oil inlet channel 161 like a valve. When the oil in the oil storage chamber 131 is exhausted, the oil sealing structure 6 can be adjusted to open the oil inlet channel 161, and the electronic cigarette 100 is inverted. At this time, the oil bottle 3 is located above the atomization module 12, and the oil in the oil bottle 3 flows into the atomizer 1 under the action of gravity. When the oil storage chamber 131 is filled with oil, the oil sealing structure 6 is reset, the oil inlet channel 161 is closed, and the electronic cigarette 100 is placed upright to complete the oil filling.

[0055] In a possible embodiment, the oil sealing structure 6 includes a guide cylinder 61 and a rotary cover 62 disposed on a section of the guide cylinder 61. The guide cylinder 61 has an oil through hole 611. The guide cylinder 61 is provided with oil sealing collars 63 on both sides of the oil through hole 611.
