DETAILED DESCRIPTION

[0033] Please refer to Figures 8-9. In an embodiment of the present invention, a heating module of an atomizer includes a middle cover 15; characterized in that a through hole 151 for smoke discharge is provided on the top of the middle cover 15, a square shell 18 is provided at the center of the middle cover 15, the square shell 18 is the only connection with the through hole 151, and other spaces of the middle cover 15 are not connected with the through hole 151, a liquid inlet component is provided on the square shell 18, a heating wire 23 is provided in the square shell 18, and the bottom of both ends of the heating wire 23 are electrically connected to conductive columns 164, the heating wire 23 is wound around the periphery of the liquid inlet component, a square opening is provided on the square shell 18, and when a person uses it, the air flow can pass through the square opening to fully inhale the atomized smoke into the mouth, and a movable mechanism cooperating with the square opening is provided on the square shell 18, and when the through hole 151 is facing downward, the movable mechanism prevents the liquid in the middle cover 15 from leaking out of the through hole 151.

[0034] Further, such as Figure 1-2As shown, an atomizer comprises an atomizer housing 1 and a mouthpiece cover 2; and also comprises a heating module of the atomizer, wherein a middle cover 15 is slidably assembled in the atomizer housing 1, an end of the atomizer housing 1 away from the middle cover 15 is provided with a mounting groove, the mouthpiece cover 2 is slidably assembled in the end of the atomizer housing 1 away from the middle cover 15 through the mounting groove, a first flue 3 is arranged at the center of the mouthpiece cover 2, a second flue 12 connected to the first flue 3 is arranged at the center of the atomizer housing 1, a top cover 14 is arranged on the top of the middle cover 15, the second flue 12 passes through the top cover 14 and is connected to a through hole 151, a liquid storage tank 11 is arranged in the atomizer housing 1, The liquid storage tank 11 is connected with the liquid outlet pipe 10 through the top cover 14; a pumping mechanism is arranged in the atomizer housing 1, and a sealing cover 13 is fixedly connected to the end of the pumping mechanism, the sealing cover 13 and the liquid outlet pipe 10 are slidably matched, and the top of the pumping mechanism is connected with the first flue 3. When the gas flows from the second flue 12 to the first flue 3, the pumping mechanism is driven to make the sealing cover 13 move away from the liquid outlet pipe 10, and the liquid in the liquid storage tank 11 can enter the liquid outlet pipe 10. When the gas does not flow, the pumping mechanism resets and drives the sealing cover 13 to block the liquid outlet pipe 10, so as to avoid the problem of liquid leakage caused by the long-term connection between the liquid outlet pipe 10 and the liquid storage tank 11.

[0035] During specific use, due to the inhalation action of the user, negative pressure will be formed in the first flue 3 and the second flue 12, firstly the pumping mechanism will be driven, and then the sealing cover 13 will move away from the liquid inlet assembly, while the liquid storage tank 11 is connected with the liquid inlet assembly, so that the liquid in the liquid storage tank 11 enters the liquid inlet assembly, and is heated and atomized by the cooperation of the heating wire 23 and the conductive column 164 of the heating module, while the outside air enters the middle cover 15 and passes through the through hole 151 to wrap the atomized smoke, and then passes through the connecting sleeve 141 and the second flue 12 and finally enters the user's mouth.

[0036] Specifically, in the above structure Figure 10-12As shown, the movable mechanism includes a baffle 24 and a driving assembly; the square housing 18 is the only one connected to the through hole 151, and the other spaces of the middle cover 15 are not connected to the through hole 151. The baffle 24 is rotatably arranged inside the square housing 18, and the two sides of the baffle 24 are fixedly connected with a rotating shaft 20, and the end of the rotating shaft 20 away from the baffle 24 is fixedly connected with a gear 25, and the rotating shaft 20 is rotatably connected to the side wall of the square housing 18, and the driving assembly is slidably matched with the square opening and is transmission-connected with the gear 25; the driving assembly includes a partition plate 21 and a rack 26; the partition plate 21 is arranged on the square housing 18, and the rack 26 and the partition plate 21 are close to the gear 25. One side of the square cover 18 is fixedly connected, the rack 26 is meshed with the gear 25, the partition plate 21 is slidably matched with the square opening, and the square opening can be blocked when the partition plate 21 slides toward the square opening; the liquid inlet component includes a liquid guide 22, both ends of the liquid guide 22 pass through the side walls of the square shell 18, and the two groups of side walls of the square shell 18 are respectively provided with mounting blocks 17 and fixing plates 19, and the tops of both ends of the liquid guide 22 are provided with liquid outlet pipes 10, and the liquid outlet pipes 10 pass through the top side walls of the middle cover 15, and the two ends of the liquid guide 22 extend into the mounting blocks 17, and the mounting blocks 17 can receive excess liquid at the connection between the liquid guide 22 and the liquid outlet pipe 10.

[0037] It should be noted that the size of the baffle 24 is larger than the second flue 12. When the user does not use the atomizer upside down, the partition plate 21 is in the storage groove, and the plane of the baffle 24 is parallel to the rack 26, so as not to affect the user's feeling in normal state.

[0038] During specific use, when the user lies flat, since the atomizer is in a vertical state, the partition plate 21 will slide out of the storage groove under the action of gravity and fit with the side of the square opening away from the heating wire 23, thereby blocking the square opening to prevent the accumulated liquid in the mounting block 17 from entering the square housing 18 through the square opening in the vertical state. The sliding of the partition plate 21 drives the rack 26 to move, so that the gear 25 meshing therewith rotates, driving the rotating shaft 20 to rotate 90°, so that the baffle 24 is horizontal with the through hole 151 after rotating 90°, and since the diameter of the baffle 24 is larger than the diameter of the through hole 151, at this time, the liquid on the liquid guide 22 is not When the liquid is heated and atomized by the heating wire 23, dripping may occur. If there is dripping, it will be blocked by the blocking piece 24 to prevent the dripping liquid from entering the second flue 12 through the through hole 151 and finally dripping vertically into the user's mouth, so as to avoid unnecessary influence on the user. When the user inhales, the heating wire 23 is energized to heat and atomize the liquid on the liquid guide 22. Because a large amount of atomized liquid is inhaled when a person lies flat, it is easy to be choked. Therefore, the square opening is blocked by the partition plate 21 and the blocking piece 24 acts. At this time, the amount of atomized liquid inhaled by the person can be reduced, avoiding the problem of choking caused by excessive inhalation of smoke when the user lies flat.

[0039] like Figure 2-3 , Figure 5-6 As shown, the pumping mechanism includes a piston tube 7 and a movable column 8; the end of the piston tube 7 away from the second flue 12 is fixedly connected to the suction nozzle sleeve 2, and the piston tube 7 is a hollow structure, a square tube 5 is arranged between the piston tube 7 and the first flue 3, the square tube 5 is a hollow structure and makes the piston tube 7 and the first flue 3 communicate with each other, the end of the piston tube 7 away from the suction nozzle sleeve 2 is sealed and clamped with the side wall connection of the mounting groove close to 12, a spring 6 is arranged inside the piston tube 7, and the end of the spring 6 away from the square tube 5 is provided with a movable column 8, the end of the movable column 8 close to the piston tube 7 is a disc structure and is slidably embedded in the inner wall of the atomizer housing 1, the end of the movable column 8 away from the spring 6 passes through the inner wall of the atomizer housing 1 and extends into the liquid storage bin 11, and the end of the movable column 8 away from the piston tube 7 is fixedly connected with a sealing cover 13;

[0040] During specific use, due to the user's inhalation action, negative pressure will be formed in the first flue 3 and the second flue 12. First, the air in the piston tube 7 will also be sucked away to form negative pressure. Because the end of the piston tube 7 is sealed with the raised part of the bottom of the installation groove, the movable column 8 is driven to move in the direction of the square tube 5 under the negative pressure, so that the spring 6 is compressed and the sealing cover 13 moves in the direction of the square tube 5 and leaves the liquid outlet pipe 10 at the same time, so that the liquid storage tank 11 is connected with the liquid outlet pipe 10, so that the liquid in the liquid storage tank 11 enters the liquid outlet pipe 10, is absorbed by the liquid guide 22, and then is heated and atomized by the heating wire 23. Each inhalation action of the user will cause the liquid in the liquid storage tank 11 to first enter the liquid outlet pipe 10 and finally be absorbed by the liquid guide 22, thereby avoiding the problem of leakage when the existing barrel cover liquid guide cotton directly contacts the liquid storage tank 11 for liquid conduction when not in use for a long time.

[0041] like Figure 1-2 , Figure 7 , Figure 13-14As shown, a protruding portion is provided inside the nozzle sleeve 2, and elastic blocks 4 are provided on both sides of the protruding portion of the nozzle sleeve 2 close to the atomizer housing 1, and the nozzle sleeve 2 is clamped on the atomizer housing 1 through the elastic blocks 4, and a liquid absorbent cotton 9 is provided on the outer side wall of one end of the first flue 3 close to the second flue 12, and the liquid absorbent cotton 9 is arranged on the inner side wall of the atomizer housing 1 close to the second flue 12, and the liquid absorbent cotton 9 is sleeved on the piston tube 7 and the outer side wall of the first flue 3; a connecting sleeve 141 is provided on the top center side wall of the top cover 14, and the end of the connecting sleeve 141 away from the top cover 14 is adapted to the size of the second flue 12, and the connection between the connecting sleeve 141 and the second flue 12 is sealed and clamped, the through hole 151 is the same size as the connecting sleeve 141, the liquid outlet pipe 10 is fixedly arranged on both sides of the top cover 14 located at the connecting sleeve 141, the side of the sealing cover 13 away from the movable column 8 is slidably matched with the top of the top cover 14, and the sealing cover 13 close to 14 A sealing block that slides with the liquid outlet pipe 10 is provided on the side; a bottom cover 16 is provided at one end of the middle cover 15 away from the top cover 14, and a first air inlet 163 and a second air inlet 161 arranged on both sides of the first air inlet 163 are provided on the bottom cover 16, and a conical sleeve 162 is provided between the first air inlet 163 and the second air inlet 161 inside the bottom cover 16, and the conical sleeve 162 is used to install and protect the conductive column 164, and the conductive column 164 is slidably arranged in the conical sleeve 162; the diameter of the first flue 3 is smaller than the diameter of the second flue 12, and the extended end of the first flue 3 extends into the second flue 12, the top cover 14, the middle cover 15 and the bottom cover 16 are slidably assembled in the end of the atomizer housing 1 away from the mouthpiece cover 2 in turn, and the outer side walls of the top cover 14, the middle cover 15 and the bottom cover 16 are all provided with sealing grooves, and the sealing strips arranged at the corresponding positions of the atomizer body 1 correspond to each other, which is convenient for installation by personnel and avoids leakage.

[0042] It should be noted that, in the initial state, the mouthpiece cover 2, the top cover 14, the middle cover 15 and the bottom cover 16 have been assembled on the atomizer housing 1, the spring 6 is in a normal state, and the sealing cover 13 is attached to the top cover 14 under the action of the movable column 8 and separates the liquid outlet pipe 10 from the liquid storage tank 11;

[0043] For specific use, refer to Figure 2, one end of the middle cover 15 close to the bottom cover 16 extends into the bottom cover 16, and there is a gap between the part of the middle cover 15 extending into the bottom cover 16 and the bottom cover 16, so that when the user is upside down or tilted, the accumulated liquid in the bottom cover 16 is prevented from flowing into the middle cover 15; when in use, the liquid guide 22 will fully absorb and store the liquid in the liquid outlet pipe 10, and the liquid on the liquid guide 22 will be atomized when the heating wire 23 is heated, and the external air enters through the first air inlet 163 and the auxiliary airway conical sleeve 162. Since the first air inlet 163 and the air outlet of the conical sleeve 162 are located higher than the bottom of the bottom cover 16, the air will not interact with the accumulated liquid in the bottom cover 16 when it is out, and similarly, the accumulated liquid will not leak out through the conical sleeve 162 and the first air inlet 163. The air entering the first air inlet 163 directly passes through the bottom of the square shell 18, the heating wire 23, the second flue 1 2 and the first flue 3 enter the user's mouth, while the air entering the conical sleeve 162 will pass through the gap between the outside of the square shell 18 and the middle cover 15 and enter the square shell 18 through the square opening, and finally enter the user's mouth through the through hole 151, the second flue 12 and the first flue 3. The two can cooperate to fully take away the smoke atomized by the heating wire 23 in the square shell 18. When there is liquid that is not completely atomized in the atomized liquid, it will adhere to the inner wall of the second flue 12 and be sucked by the user toward the direction of the mouthpiece sleeve 2, and finally enter the user's mouth. When the second flue 12 and the first flue 3 are moved to the interface, since the diameter of the first flue 3 is smaller than the diameter of the second flue 12, the liquid will be absorbed by the liquid-absorbing cotton 9 arranged in the mounting groove at the end of the second flue 12, thereby preventing the liquid from entering the user's mouth to avoid causing adverse effects.
