For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0034] Figure 1The first embodiment of the electronic atomization system of the present invention is shown. The electronic atomization system includes an electronic atomization device 100 and a liquid storage device 200. The electronic atomization device 100 is used to atomize a liquid matrix for users to inhale. It has the advantages of simple structure, convenient transportation, not easy to leak, good taste of the generated aerosol, and high user experience. In this embodiment, the liquid matrix may include tobacco oil or liquid medicine, etc. In this embodiment, the liquid storage device 200 can store liquid matrix, replenish the liquid matrix for the electronic atomization device 100, and thereby ensure the quality of the liquid matrix in the electronic atomization device 100.

[0035] like Figure 1 As shown, in this embodiment, the electronic atomization device includes an atomization shell 10, an atomization component (not shown) and a liquid injection and exhaust structure 20. A liquid storage chamber 11 can be formed inside the atomization shell 10 for storing liquid matrix. The atomization component (not shown) is accommodated in the atomization shell 10 and is used to atomize the liquid matrix in the atomization shell 10. The liquid injection and exhaust structure 20 is connected to the liquid storage device 200 and the liquid storage chamber 11, and is used to inject the liquid matrix in the liquid storage device 200 into the liquid storage chamber 11, and at the same time, the gas in the liquid storage chamber 11 can be discharged.

[0036] In this embodiment, the liquid storage chamber 11 is provided with an air outlet pipe 12 and a liquid inlet pipe 13. The air outlet pipe 12 can be arranged along the liquid level rising and falling direction of the liquid storage chamber 11, and can extend from the lowest liquid level to the highest liquid level of the liquid storage chamber 11. The length of the air outlet pipe 12 is higher than the highest liquid level in the liquid storage chamber, thereby preventing the liquid matrix from being discharged from the air outlet pipe 12. The liquid inlet pipe 13 can be arranged at the bottom of the liquid storage chamber 11, and the liquid matrix can enter the liquid storage chamber 11 through the liquid inlet pipe 13, and the gas in the liquid storage chamber 11 can be discharged through the air outlet pipe 12.

[0037] like Figures 2 to 5As shown, in the present embodiment, the liquid injection and exhaust structure 20 is connected to the atomizing shell 10, and can be loaded into the battery housing of the electronic atomizing device 100 together with the atomizing shell 10. In some other embodiments, the liquid injection and exhaust structure 20 can be installed in the atomizing shell 10, or independently arranged outside the atomizing shell 10 or the battery housing. The liquid injection and exhaust structure 20 can be a peristaltic pump structure, which may include a support 21, a shell 22, an extrusion mechanism 23, an injection tube 24 and an exhaust pipe 25. In the present embodiment, the support 21 is used to support components such as the shell 22, the extrusion mechanism 23, the injection tube 24 and the exhaust pipe 25. The shell 22 can be arranged on the support 21 for installation of the extrusion mechanism 23, the injection tube 24 and the exhaust pipe 25. The squeezing mechanism 23 is arranged in the housing 22, and can squeeze and release the injection tube 24 and the exhaust pipe 25 at the same time, and by squeezing and releasing the injection tube 24 and the exhaust pipe 25, negative pressure is generated locally in the injection tube 24 and the exhaust pipe 25, forming a pressure difference, so that the liquid matrix in the liquid storage device 200 is sequentially sent into the liquid storage chamber 11 through the injection tube 24 and the liquid inlet pipe 13, and at the same time, the gas in the liquid storage chamber 11 is sequentially discharged through the gas outlet pipe 12 and the exhaust pipe 25. The injection tube 24 and the exhaust pipe 25 are arranged side by side, and both are penetrated from the housing 22. Among them, one end of the injection tube 24 is connected to the liquid storage chamber 11, and the other end is connected to the liquid storage device 200. One end of the exhaust pipe 25 is connected to the liquid storage chamber 11, and the other end can be connected to the outside through the liquid storage device 200, or can be directly connected to the outside.

[0038] In the present embodiment, the support 21 may include a first support plate 211, a second support plate 212, and a first support column 213. In the present embodiment, the first support plate 211 and the second support plate 212 are parallel and spaced apart. The first support column 213 is disposed between the first support plate 211 and the second support plate 212, and the two ends are connected to the first support plate 211 and the second support plate 212, respectively. In some embodiments, there are multiple first support columns 213, and the multiple first support columns 213 are spaced apart. In the present embodiment, the support 21 also includes a third support plate 214 and a second support column 215, and the size of the third support plate 214 is smaller than the size of the first support plate 211, and its specific length is smaller than the length of the first support plate 211. The third support plate 214 is parallel to the first support plate 211 and spaced apart. The second support column 215 is disposed between the third support plate 214 and the first support plate 211 , and two ends thereof are respectively connected to the third support plate 214 and the first support plate 211 . There are a plurality of second support columns 215 , and the plurality of second support columns 215 are disposed at intervals.

[0039] In this embodiment, the housing 22 is fixedly disposed on the third support plate 214. The housing 22 may include a body 221 and a cover 222. The body 221 may be fixedly mounted on the third support plate 214, and a receiving cavity 2210 having an opening is formed inside the body 221 for receiving the extrusion mechanism 23. The cover 222 may be covered on the body 221 to cover the opening of the receiving cavity 220.

[0040] like Figure 6 As shown, in this embodiment, the squeezing mechanism 23 can be rotatably arranged between the injection pipe 24 and the exhaust pipe 25, and can realize the simultaneous squeezing and loosening of the injection pipe 24 and the exhaust pipe 25 by rotation. In this embodiment, the squeezing mechanism 23 may include a rotating bracket 231 and a roller assembly 232. The rotation axis of the rotating bracket 231 is located on the same straight line as the center of the body 221. The rotating bracket 231 can be placed between the injection pipe 24 and the exhaust pipe 25 and rotate. The roller assembly 232 is arranged on the rotating bracket 231, and the rotating bracket 231 is rotated to drive the rotating bracket to rotate along the rotation axis of the rotating bracket, thereby realizing squeezing and loosening the injection pipe 24 and the exhaust pipe 25.

[0041] In this embodiment, the rotating bracket 231 includes a first end 231a, a connecting portion 231c and a second end 231b. The first end 231a and the second end 231b are respectively located at the two ends of the connecting portion 231c. The first end 231a includes at least three first extension portions 2311 arranged at intervals and extending outward. Two adjacent first extension portions 2311 may be arranged at a set angle, and the set angle may be greater than or equal to 90 degrees and less than 180 degrees. The second end 231a includes at least three second extension portions 2312 arranged at intervals and extending outward. Two adjacent second extension portions 2312 may be arranged at a set angle, and the set angle may be greater than or equal to 90 degrees and less than 180 degrees. The first extension portion 2311 and the second extension portion 2312 are arranged one by one, and the first extension portion 2311 and the second extension portion 2312 are arranged opposite to each other. The first extension portion 2311 and the second extension portion 2312 are both provided with mounting holes 2313. The mounting holes 2313 on the first extension portion 2311 and the second extension portion 2312 are coaxially arranged. A through hole 2310 is arranged at the central axis of the connecting portion 231c, and the through hole 2310 can be passed through by the rotating shaft. Specifically, in this embodiment, there can be four first extension portions 2311 and four second extension portions 2312. The four first extension portions 2311 and the four second extension portions 2312 can be equidistantly arranged.

[0042] In this embodiment, the roller assembly 232 may include at least two rollers 2321. Further, in some embodiments, the rollers 2321 may be at least three. Each roller 2321 may be arranged in a one-to-one correspondence with the first extension 2311 and the second extension 2312. Each roller 2321 is located between the first extension 2311 and the second extension 2312. Both ends of each roller 2321 have a fixed shaft 2322, and the fixed shaft 2322 may be penetrated in the corresponding mounting hole 2313. In this embodiment, the rollers 2321 may be four. Of course, it can be understood that in some other embodiments, the rollers 2321 are not limited to four, and may be three or more than four. It should be noted that the reason why the number of rollers 2321 is greater than or equal to three can solve the problem of air leakage caused by the dead point of the rollers 2321. If there are two rollers 2321, when the rollers 2321 rotate until the gaps between the two rollers 2321 and the injection tube 24 and the exhaust tube 25 are in the same direction, the injection tube 24 and the exhaust tube 25 may not be pressed tightly, resulting in the liquid storage chamber 11 being connected to the liquid storage device 200, which not only reduces the efficiency of injection and exhaust, but also has the risk of leakage. When there are three or more rollers 2321, the injection tube 24 and the exhaust tube 25 can be pressed tightly at any position, thereby ensuring the isolation of the liquid storage chamber 11 and the liquid storage device 200, improving the efficiency of injection and exhaust, and reducing the risk of leakage.

[0043] In this embodiment, the distance from the outer surface of the roller assembly 232 to the inner wall of the shell 22 is 0.2 mm greater than twice the wall thickness of the injection tube 24, and the distance from the outer surface of the roller assembly 232 to the inner wall of the shell 22 is 0.2 mm greater than twice the wall thickness of the exhaust pipe 25, that is, the distance from the outer surface of each roller 2321 to the inner wall of the shell 22 is 0.2 mm greater than twice the wall thickness of the injection tube 24, and 0.2 mm greater than twice the wall thickness of the exhaust pipe 25, thereby ensuring that the roller assembly 232 can press the injection tube 24 and the exhaust pipe 25.

[0044] For example Figures 3 to 5 As shown, in this embodiment, the injection tube 24 can be a deformable pipe, such as a hose. Specifically, in some embodiments, the injection tube 24 can be a silicone tube, a rubber tube or a TPE tube. Part of the tube wall of the injection tube 24 is close to or in contact with the inner wall of the shell 22. Specifically, the tube wall of one side of the tube section of the injection tube 24 located in the shell 22 can be in contact with the inner wall of the shell 22, so that the roller assembly can squeeze the injection tube 24 toward the inner wall of the shell 22, and the roller 2321 can cooperate with the inner wall of the shell 22 to squeeze the injection tube 24.

[0045] In this embodiment, the exhaust pipe 25 may be a deformable pipe, such as a hose. Specifically, the exhaust pipe 25 may be a silicone tube, a rubber tube or a TPE tube. The exhaust pipe 25 may be arranged in parallel with the injection tube 24. In this embodiment, part of the wall of the exhaust pipe 25 is close to or in contact with the inner wall of the shell 22. Specifically, the wall of one side of the pipe section of the exhaust pipe 25 located in the shell 22 may be in contact with the inner wall of the shell 22, so that the roller assembly can squeeze the exhaust pipe 25 toward the inner wall of the shell 22, and the roller 2321 can cooperate with the inner wall of the shell 22 to squeeze the exhaust pipe 25.

[0046] Under the action of the same rotation direction of the extrusion mechanism 23, the injection pipe 24 and the exhaust pipe 25 can respectively form pressure differences in different directions and have the same rotation speed, thereby achieving the functions of synchronous injection and exhaust, ensuring the independence of the liquid storage device 200 and the liquid storage chamber 11 without causing pressure changes.

[0047] In this embodiment, the electronic atomization device 100 further includes a driving mechanism 26, which is mounted on the first support plate 211 and is distributed transversely with the extrusion mechanism 23, that is, distributed along the length direction of the first support plate 211. Specifically, it can be connected and fixed to the first mounting plate 211 by connecting components such as screws. In this embodiment, the driving mechanism 26 can be a motor. In this embodiment, the driving mechanism 26 can drive the extrusion mechanism 23 to move, specifically, it can drive the rotating bracket 231 to rotate.

[0048] In this embodiment, the electronic atomization device 100 also includes a transmission mechanism 27, which is mounted on the support 21 and connected to the drive mechanism 26 and the extrusion mechanism 23, and can drive the extrusion mechanism 23 to rotate under the drive of the drive mechanism 26. In this embodiment, the transmission mechanism 27 can be a gear assembly. Specifically, the transmission mechanism 27 may include a first gear 271, a second gear 272 meshing with the first gear 271, and a rotating shaft 273, and the rotating shaft 273 has a third gear meshing with the second gear 272. The first gear 271 and the second gear 272 may be installed between the first support plate 211 and the second support plate 212. The rotating shaft 273 may pass through the third support plate 214, and may pass through the housing 22, and then pass through the through hole 2310 of the rotating bracket 231. In some other embodiments, the transmission mechanism 27 may be omitted, and the drive mechanism 26 may be directly connected to the extrusion mechanism 23.

[0049] In this embodiment, the liquid storage device 200 may include a liquid storage tank 201. The liquid storage tank 201 may be provided with a liquid supply pipe 203 and an airway pipe 202, wherein the airway pipe 202 may be arranged higher than the highest liquid level of the liquid storage tank 201, the airway pipe 202 may be connected to the exhaust pipe 25, and the gas discharged from the exhaust pipe 25 may be discharged through the airway pipe 202. The liquid supply pipe 203 may be connected to the liquid injection pipe 24, and the liquid supply pipe 203 discharges the liquid matrix in the liquid storage tank 201 to the liquid injection pipe 24.

[0050] Figure 7 The second embodiment of the electronic atomization system of the present invention is shown, which differs from the first embodiment in that the squeezing mechanism 23 , the transmission mechanism 27 and the driving mechanism 26 can be arranged in sequence along a direction perpendicular to the support 21 .

[0051] Figure 8 A third embodiment of the electronic atomization system of the present invention is shown, which differs from the first embodiment in that the transmission mechanism 27 and the driving mechanism 26 can be arranged in a direction perpendicular to the support 21 , and the squeezing mechanism 23 can be located on one side of the transmission mechanism 27 .

[0052] It can be understood that 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. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
