[0035] See also Figure 1 to Figure 4, the electronic atomization device provided in this embodiment is now described. The electronic atomization device 100 in this embodiment includes a housing 11, an atomizer 1, a main control unit 2, a liquid reservoir 3 and an oil sealing structure 6. The atomizer 1 is provided with an oil storage chamber 131. The oil storage chamber 131 has a visualization area, and the user can observe the remaining amount of smoke oil in the oil storage chamber 131 in real time. The middle part of the housing 11 is provided with a first accommodating chamber 111 and a second accommodating chamber 112 side by side, one end of the housing 11 is provided with an opening (not shown in the figure), and the inner cavity of the housing 11 is located below the opening and is provided with a mounting position (not shown in the figure), the atomizer 1 is fixed in the mounting position, and part of the atomizer 1 extends through the opening. The part extending out of the opening in the atomizer 1 can be configured as a cigarette holder 13, and the cross-section of the cigarette holder 13 is elliptical, which is ergonomic and improves the comfort of suction. The main control unit 2 and the liquid reservoir 3 are placed in the first accommodating chamber 111 and the second accommodating chamber 112 in sequence. The first accommodating chamber 111 is unobstructed, which is conducive to the disassembly or assembly of the main control unit 2. 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 first accommodating chamber 111 by snaps, threads, adhesives, or magnetic suction. Correspondingly, the liquid reservoir 3 can also be fixed to the second accommodating chamber 112 in a detachable manner. The atomizer 1 is provided with a connecting oil inlet channel 161, and the two ends of the oil inlet channel 161 are connected to the oil storage chamber 131 and the liquid reservoir 3 respectively. The oil sealing structure 6 is similar to a valve and can be arranged on the liquid reservoir 3 or the oil inlet channel 161. When the oil sealing structure 6 is in a closed state, the smoke oil in the liquid reservoir 3 cannot flow into the atomizer 1; when the oil sealing structure 6 is in a conducting state, the electronic atomization device 100 is inverted, and the smoke oil in the liquid reservoir 3 flows to the atomizer 1 under the action of gravity, so that the smoke oil in the atomizer 1 is replenished in time.

[0036] In this embodiment, a liquid reservoir 3 and an oil sealing structure 6 are additionally provided in the electronic atomization device 100. The liquid reservoir 3 and the atomizer 1 are connected. The oil sealing structure 6 is similar to a valve and can be provided on the liquid reservoir 3 or the oil inlet channel 161. When the oil sealing structure 6 is in a closed state, the smoke oil in the liquid reservoir 3 cannot flow into the atomizer 1. When the oil sealing structure 6 is in a conducting state, the electronic atomization device 100 is inverted, and the smoke oil in the liquid reservoir 3 flows to the atomizer 1 under the action of gravity, and the smoke oil in the atomizer 1 is replenished in time to meet the user's requirements for large capacity. In addition, the liquid reservoir 3 and the main control unit 2 are respectively fixed to the housing 11 in a detachable manner. When disassembling and assembling, the liquid reservoir 3 and the main control unit 2 are not blocked and can be quickly disassembled and assembled to achieve classified recycling, which meets the requirements of environmental protection.

[0037] In a possible embodiment, a first retaining member 171 is provided in the first accommodating cavity 111, and correspondingly, a second retaining member 26 adapted to the first retaining member 171 is provided on the outer wall of the main control unit 2. The two retaining members cooperate with each other to generate a force so that the component is fixed to a certain position. Preferably, the fixing member is a magnetic member, and due to the magnetic attraction of the magnetic member, the main control unit 2 is fixed in the first accommodating cavity 111. This fixing method is simple and convenient for disassembly.

[0038] The cartridge-changing electronic atomization device 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. 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 liquid reservoir 3 and the main control unit 2 are arranged side by side on the housing 11, with a short length, easy to carry, and 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. The liquid reservoir 3 and the main control unit 2 are exposed outside the housing 11, and the two structures can be quickly removed from the housing 11, thereby improving the disassembly and assembly efficiency, and the components can be quickly recovered. In addition, the liquid reservoir 3 is added to the electronic atomization device 100, and the oil can be replenished in time to overcome the problem of small oil capacity of the cartridge-changing electronic atomization device 100.

[0039] The main control unit 2 is generally rectangular and is electrically connected to the atomizer 1 through the spring pin 7. When the main control unit 2 is limited to the first accommodating chamber 111, the upper and lower end surfaces of the main control unit 2 and a side wall that abuts against the first accommodating chamber 111 are called matching surfaces 28, and the remaining three sides are exposed to the outside of the housing 11, which are called non-matching surfaces 29. The electronic atomization device 100 also includes a display screen 23, which is electrically connected to the main control unit 2. The display screen 23 is an interface for human-computer interaction. The user can control the working condition of the electronic atomization device 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 29 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 screen 23 can be set according to actual conditions, and the display screen 23 can be distributed on one or more side walls of the main control unit 2.

[0040] The aerosol 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 from the housing of the electronic atomization device 100, it can be used as a mobile power source.

[0041] In one possible implementation, see Figure 1 , Figure 5 and Figure 6 The liquid reservoir 3 is a cylindrical bottle-like structure, which is generally white in color and can store 7 ml of smoke oil. The oil storage chamber 131 can be filled with oil in time, which solves the problem that the previous electronic atomization device 100 needs to use professional tools for oil filling or needs to carry extra smoke oil. The liquid reservoir 3 can be made of transparent or plate-transparent plastic, tempered film or glass. Correspondingly, the area of ​​the housing 11 located in the oil storage chamber 131 is at least partially made transparent, so that the user can observe the remaining smoke oil in the oil storage chamber 131 in time and replenish the smoke oil in the oil storage chamber 131 in time. Of course, in some embodiments, the liquid reservoir 3 can also be a soft oil bag with elastic deformation. The soft oil bag is similar to the sealed bag of product packaging. It can be understood that all utensils that can store smoke oil can be the liquid reservoir 3, and there is no limitation here.

[0042] In a possible embodiment, a side cover 4 is provided on the side of the housing 11 facing away from the main control unit 2. The side cover 4 can be fixed to the housing 11 by means of magnetism, snap-fit, or hinge. The side cover 4 and the housing 11 enclose a second accommodating cavity 112, and the second accommodating cavity 112 accommodates the liquid reservoir 3. A side cover 4 is provided on the outer peripheral side of the liquid reservoir 3 to effectively avoid damage to the smoke liquid reservoir 3 in the event of a collision. The side cover 4 can be made of transparent, opaque or non-transparent 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, and the user observes the remaining smoke oil in the liquid reservoir 3 through the hollow holes 41.

[0043] Preferably, at least one side of the side cover 4 is movably connected to the housing 11, so that the side cover 4 is not easy to slide off the housing 11, and the two structures cooperate stably. Specifically, an insertion strip 42 extends from one end of the side cover 4, and a sliding groove 116 is provided on the corresponding side of the housing 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 distributed at intervals along the height direction of the sliding groove 116. When the liquid reservoir 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 liquid reservoir 3 is completely exposed to the housing 11.

[0044] Furthermore, a first magnetic member 43 is provided at one end of the side cover 4 located on the reservoir 3 away from the oil inlet channel 161, and a second magnetic member 172 is provided at the bottom of the mounting plate 17. When the side cover 4 is in the closed state, the two magnetic members are magnetically attracted, so that the side cover 4 is not easy to slide off the housing 11.

[0045] In one embodiment, see Figure 2 to Figure 4The atomizer 1 further includes a mouthpiece 13, an annular wall extending outward and downward from the circumference of the mouthpiece 13, and a sealing seat 15, the sealing seat 15 being arranged at the bottom of the annular wall and at the end of the sealing ring 63-shaped wall. The sealing seat 15 and the annular wall enclose an oil storage chamber 131. The oil storage chamber 131 is fixed in the housing 11, and at least part of the mouthpiece 13 protrudes from the housing 11. The housing 11 is provided with a hollow hole 41 at a position corresponding to the oil storage chamber 131, so that the user can know the remaining amount of tobacco oil in the oil storage chamber 131 in real time through the hollow hole 41. In order to pursue the aesthetics of the product, the shell 11 of the electronic atomization device 100 is often set to be irregular or have multiple curved surfaces, so the inner wall of the shell 11 is mostly uneven, and the sealing seat 15 directly cooperates with the shell 11. The sealing performance is poor, so the formed oil storage cavity 131 is prone to leakage. In addition, the part of the shell 11 located in the oil storage cavity 131 is made transparent, which is also difficult to form in the production process of the shell 11. In this embodiment, the mouthpiece 13 extends downward with an annular wall. The annular wall has good flatness and can form a close fit with the sealing seat 15, so the enclosed oil storage cavity 131 has good sealing performance.

[0046] The atomization module 12 and the cigarette holder 13 are assembled to form an independent atomizer 1. The housing 11 is composed of a front cover 113 and a rear cover 114. One side of the two covers is hinged, and the other side is matched with a buckle. When the atomizer 1 is damaged, the buckles of the two covers are loosened, so that the atomizer 1 falls off from the housing 11, which is convenient for disassembly and assembly.

[0047] In a possible embodiment, the electronic atomization device 100 further includes a mounting seat 16, which is fixed in the housing 11 and is located below the sealing seat 15. There is a gap between the mounting seat 16 and the sealing seat 15, and a first air inlet channel 163 is provided on the mounting seat 16, and the sealing seat 15 has a second air inlet channel 151 connected to the first air inlet channel 163. The housing 11 is provided with an air inlet hole 115 at the free end of the first air inlet channel 163, and an air regulating structure 5 is inserted into the air inlet hole 115. The air regulating structure 5 controls the air intake by controlling the shielding area of ​​the air inlet hole 115, thereby achieving the purpose of controlling the amount of smoke.

[0048] Furthermore, if Figure 4As shown, the mounting base 16 is located at one end of the first air inlet channel 163 away from the atomizer 1 and extends downwardly toward the main control unit 2 with a first drainage channel 162. Correspondingly, the main control unit 2 is provided with an airflow sensor 25 installed in the second drainage channel 27 at one end close to the atomizer 1, and the airflow sensor 25 is electrically connected to the main control board 22 in the main control unit 2. When the main control unit 2 is assembled to the atomizer 1, the first drainage channel 162, the second drainage channel 27, the air inlet hole 115, the first air inlet channel 163, the second air inlet channel 151 and the air outlet channel 14 form an air circuit, and the airflow sensor 25 can monitor the airflow changes in the device in real time, thereby triggering the atomizer 1 to work.

[0049] In a possible embodiment, the mounting seat 16 is provided with a mounting groove 164 at the position of the liquid reservoir 3, and the mounting groove 164 is provided with an internal thread (not shown), and the liquid reservoir 3 is correspondingly provided with an external thread 33 that matches the internal thread. The liquid reservoir 3 is fixed to the housing 11 by threaded fixing, and the threaded connection can well withstand tension and vibration, avoiding the problem of loosening due to interference from other external forces and causing leakage of smoke oil.

[0050] See also Figure 3 to Figure 6The liquid reservoir 3 includes a liquid reservoir body 31 and an upper connecting portion 32 provided on the liquid reservoir body 31. The outer peripheral side of the connecting portion 32 is provided with an external thread 33 adapted to the internal thread. The outer diameter of the connecting portion 32 is much smaller than the outer diameter of the liquid reservoir body, and a sealing member 34 is sleeved inside the connecting portion 32. The mounting seat 16 is provided with an oil inlet channel 161 extending from the bottom end of the mounting groove 164 to the connecting surface of the mounting seat 16 and the sealing seat 15. The sealing seat 15 is provided with an oil inlet hole 152. The two ends of the oil inlet hole 152 are respectively connected to the oil inlet channel 161 and the oil storage chamber 131. The oil inlet channel 161 is in the shape of 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 liquid reservoir 3 to the oil storage chamber 131. The outer wall of the mounting seat 16 is laterally provided with a slot (not shown) at a position corresponding to the oil inlet channel 161. The slot is connected to the oil inlet channel 161, and the oil sealing structure 6 is embedded in the slot. The oil sealing structure 6 is similar to a valve and can block or open the oil inlet channel 161. When the oil in the oil storage chamber 131 is exhausted, the oil sealing structure 6 can be adjusted to make the oil inlet channel 161 conductive, and the electronic atomization device 100 is inverted. At this time, the liquid reservoir 3 is located above the atomization module 12, and the oil in the liquid reservoir 3 flows into the atomization module 12 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 cut off, and the electronic atomization device 100 is placed upright to complete the oil filling. In addition, the liquid outlet of the liquid reservoir 3 is also equipped with a flow timer (not shown in the figure), and a preset oil filling time is set in the flow timer according to the oil output per unit time of the liquid outlet and the oil storage volume in the oil storage chamber 131. When the actual oil filling time exceeds the preset time, the oil inlet channel 161 is blocked to prevent excessive oil from being injected into the oil storage chamber 131 and the oil in the oil storage chamber 131 from leaking out.

[0051] In order to know the remaining amount of the oil in the oil storage chamber 131 in real time. A water level sensor (not shown) is provided at the bottom of the oil storage chamber 131, and the electronic atomization device 100 also includes a position sensor (not shown). The water level sensor and the position sensor are respectively connected to the main control unit 2 for communication. Only when the position sensor detects that the electronic atomization device 100 is in the upright position (the atomizer 1 is located above the oil bottle), the water level sensor will monitor the remaining amount of the oil in the oil storage chamber 131 in real time to avoid false alarms when the aerosol is inverted. When the remaining amount of the oil is lower than the minimum, the water level sensor will feed back the detection signal to the main control unit 2 and issue an alarm.

[0052] In a possible embodiment, the oil sealing structure 6 can be arranged on the liquid reservoir 3 similar to a valve, or on the oil inlet channel 161. Since the volume of the liquid reservoir 3 is small, it is difficult to fix the oil sealing structure 6 on the liquid reservoir 3. Preferably, the oil sealing structure 6 is arranged on the oil inlet channel 161.

[0053] Specifically, Figure 4As shown, the oil sealing structure 6 includes a guide cylinder 61 and a rotary cover 62 disposed at one end of the guide cylinder 61. The guide cylinder 61 has an oil through hole 611. The guide cylinder 61 is provided with sealing rings 63 on both sides of the oil through hole 611. When the guide cylinder 61 is inserted into the slot, the oil inlet hole 152 is just located on the oil inlet channel 161. The knob and rotary cover 62 drive the guide cylinder 61 to rotate to a suitable angle. At this time, the oil through hole 611 and the oil inlet channel 161 are on the same straight line, the oil inlet channel 161 is connected, and the smoke oil in the liquid reservoir 3 can flow from the oil inlet channel 161 into the oil storage chamber 131.

[0054] In another possible embodiment, the oil sealing structure 6 includes a ball 64 and an elastic member 65, and the slots are distributed along the lateral direction of the mounting seat 16, and form a cross-axis structure with the oil inlet channel 161. The slots divide the oil inlet channel 161 into a first oil inlet channel 1611 and a second oil inlet channel 1612. The first oil inlet channel 1611 and the second oil inlet channel 1612 are sequentially distributed on the mounting seat 16 along the direction from the liquid reservoir 3 to the atomizer 1. Figure 7 The first oil inlet channel 1611 is closer to the reservoir 3 than the second oil inlet channel 1612. The diameter of the first oil inlet channel 1611 is smaller than the diameter of the ball 64. The elastic member 65 is arranged at the port of the second oil inlet channel 1612. The ball 64 plug is arranged in the slot and located at the port of the first oil inlet channel 1611. When the electronic atomization device 100 is placed upright, the ball 64 naturally falls down under the action of gravity to block the port of the first oil inlet channel 1611. At this time, the oil inlet channel 161 is in a cut-off state, and the smoke oil in the liquid reservoir 3 cannot flow into the oil storage chamber 131; when the electronic atomization device 100 is inverted, the ball 64 moves a certain distance along the second oil inlet channel 161 under the action of gravity. Since the second oil inlet channel 1612 is provided with an elastic member 65, the elastic member 65 can push against the ball 64 to prevent the ball 64 from flowing into the second oil inlet channel 1612. Then, the first oil inlet channel 1611 and the second oil inlet channel 1612 are connected, and the smoke oil in the liquid reservoir 3 can flow into the oil storage chamber 131 through the first oil inlet channel 1611 and the second oil inlet channel 1612. A ball 64 is provided in the oil inlet channel 161, and gravity is used to realize the conduction of the oil inlet channel 161. The operation is convenient, the structure is simple, and the installation is convenient.
