[0036] Example 1

[0037] like Figure 1-3As shown, an embodiment of the present invention provides an atomizer, which includes a liquid storage cup 1, an atomizer bracket 2, an atomizer tube 3 and a stretching piece 4. One end of the liquid storage cup 1 is configured with a suction nozzle 11, the atomizer bracket 2 is arranged at the mouth of the liquid storage cup 1 away from the suction nozzle 11, one end of the atomizer tube 3 is telescopically plugged into the suction nozzle 11, and the other end of the atomizer tube 3 extends toward the atomizer bracket 2. The stretching piece 4 can be plugged and locked with the atomizer tube 3 via the suction nozzle 11, so that the end of the atomizer tube 3 away from the suction nozzle 11 is spaced or abutted against the atomizer bracket 2.

[0038] In this embodiment, one end of the atomizer tube 3 is retractably plugged with the suction nozzle 11, and the other end of the atomizer tube 3 is extended toward the atomizer bracket 2. Since the stretching member 4 can be plugged and locked with the atomizer tube 3 via the suction nozzle 11, the end of the atomizer tube 3 away from the suction nozzle 11 can be spaced or abutted against the atomizer bracket 2. When the end of the atomizer tube 3 away from the suction nozzle 11 is spaced from the atomizer bracket 2, the atomized liquid in the liquid storage cup 1 enters the atomizer tube 3 through the gap. When the frame 2 is against each other, the space for storing the atomized liquid in the liquid storage cup 1 is separated from the inside of the atomization tube 3. Therefore, the atomizer of this embodiment can cooperate with the atomization tube 3 through the stretching piece 4 to separate the space for storing the atomized liquid in the liquid storage cup 1 from the inside of the atomization tube 3 before the electronic atomization device is shipped to the consumer for use, thereby preventing leakage from causing the product to start automatically and causing safety accidents, preventing leakage from causing the atomized liquid to leak out of the outer surface of the product and affecting the product appearance, and preventing excessive leakage from affecting the number of uses of the product.

[0039] In some embodiments, the suction nozzle 11 is constructed with a first docking tube 111 extending toward the atomization tube 3 and inserted at one end of the atomization tube 3, an annular rib plate 31 is constructed inside the atomization tube 3, and the inner hole of the annular rib plate 31 is constructed with a second docking tube 311, the outer wall of one end of the stretching member 4 is constructed with an external thread, and the inner wall of the second docking tube 311 is constructed with an internal thread. In this embodiment, the stretching member 4 can be inserted and locked with the atomization tube 3 through the suction nozzle 11 through the cooperation between the external thread of the stretching member 4 and the internal thread of the inner wall of the second docking tube 311, so that the end of the atomization tube 3 away from the suction nozzle 11 is spaced or abutted against the atomization bracket 2, which can prevent liquid leakage from causing safety accidents caused by self-starting of the product, prevent liquid leakage from causing the atomized liquid to leak out of the outer surface of the product and affect the product appearance, and at the same time prevent excessive leakage from affecting the number of mouths of the product.

[0040] In some embodiments, the suction nozzle 11 is constructed with a first docking tube 111 extending toward the atomizer tube 3 and inserted at one end of the atomizer tube 3, an annular rib plate 31 is constructed inside the atomizer tube 3, one end of the stretching member 4 is constructed with an inwardly contracted groove 41 extending radially through the axial direction, and an outer wall of the stretching member 4 is constructed with a locking protrusion 42 on at least one side away from the inwardly contracted groove 41, and an outer periphery of the stretching member 4 is located on a side of the locking protrusion 42 facing the suction nozzle 11 and is constructed with a blocking portion 43. When one end of the stretching member 4 is inserted into the inner hole of the annular rib plate 31, the locking protrusion 42 and the blocking portion 43 are located on both axial sides of the annular rib plate 31. Therefore, the structure of this embodiment enables the stretching member 4 to be inserted and locked with the atomizer tube 3 via the suction nozzle 11, so that the end of the atomizer tube 3 away from the suction nozzle 11 is spaced or abutted against the atomizer bracket 2, which can prevent leakage from causing safety accidents caused by self-starting of the product, prevent leakage from causing atomized liquid to leak out of the outer surface of the product and affect the product appearance, and at the same time prevent excessive leakage from affecting the number of mouths of the product.

[0041] After the stretching member 4 and the atomizing tube 3 are inserted and locked, and the atomizing tube 3 is pulled to the uppermost position, the pulling force can be increased. At this time, the inner contraction groove 41 can cause the locking protrusion 42 to shrink inward, so that the stretching member 4 and the atomizing tube 3 are unlocked.

[0042] In some embodiments, a first sealing member 5 is disposed between the outer wall of the first butt joint 111 and the inner wall of the atomizing tube 3 , and a plurality of first annular sealing protrusion structures 51 are configured on the outer periphery of the first sealing member 5 to further improve the sealing performance.

[0043] In some embodiments, the nebulizer further includes an airway sleeve 6, wherein the airway sleeve 6 is partially inserted into the first docking tube 111, and the airway sleeve 6 is configured with a flange 61 away from the suction nozzle 11, and the flange 61 is arranged at an end of the first sealing member 5 away from the suction nozzle 11 to prevent the first sealing member 5 from detaching and causing leakage.

[0044] In some embodiments, the atomizer also includes a second sealing member 7 wrapped around the outer periphery of the atomizer bracket 2 and the side of the atomizer bracket 2 facing the nozzle 11. The second sealing member 7 is configured with a third docking tube 71 extending toward the nozzle 11 and connected to the side away from the nozzle 11. When the atomizer tube 3 moves toward the atomizer bracket 2, the third docking tube 71 can be inserted into the atomizer tube 3 to further improve the sealing performance and prevent liquid leakage.

[0045] In some embodiments, the outer wall of the third butt joint 71 is configured with a plurality of second annular sealing protrusion structures 711 to further improve the sealing performance and prevent liquid leakage.

[0046] In some embodiments, the atomizer bracket 2 is configured with a fourth butt joint pipe 21 extending toward the nozzle 11 and communicating with a side away from the nozzle 11 . The fourth butt joint pipe 21 is inserted into the third butt joint pipe 71 to facilitate assembly of the second sealing member 7 .

[0047] In some embodiments, a first tubular liquid-conducting member 8, a second tubular liquid-conducting member 9 and a heating member 10 are disposed in the atomizing tube 3. The first tubular liquid-conducting member 8 is disposed in the atomizing tube 3 and is located on a side of the annular rib plate 31 away from the suction nozzle 11. The second tubular liquid-conducting member 9 is disposed in the first tubular liquid-conducting member 8. The heating member 10 is disposed in the second tubular liquid-conducting member 9.
