[0040] Example 1

[0041] like Figure 1-5 As shown, the embodiment of the utility model provides an atomizer, the atomizer comprising:

[0042] A liquid storage cup assembly is provided with an airway tube 2 whose two ends are connected to the outside, and a liquid inlet hole 21 is opened on the airway tube 2 so that the inside thereof is connected to the liquid storage chamber of the liquid storage cup assembly;

[0043] The atomizing assembly can be inserted into the airway tube 2 through the air inlet end of the airway tube 2, and the atomizing assembly includes an atomizing tube 41 and a tubular heating module 42. The atomizing tube 41 is provided with a liquid passage hole 411 arranged opposite to the liquid inlet hole 21, and the tubular heating module 42 includes a ceramic tubular liquid-conducting matrix 421 and a heating mesh tube 422 arranged in the inner hole of the ceramic tubular liquid-conducting matrix 421;

[0044] Among them, in the axial direction of the atomization tube 41, the distance between the end of the heating mesh tube 422 away from the air inlet end and the end of the ceramic tubular liquid-conducting substrate 421 away from the air inlet end is L1, the distance between the end of the heating mesh tube 422 close to the air inlet end and the end of the ceramic tubular liquid-conducting substrate 421 close to the air inlet end is L2, and the length of the heating mesh tube 422 is L0, L0>L1, L0>L2, L0≥L1+L2.

[0045] In this embodiment, in order to achieve a better taste and experience effect, in the axial direction of the atomizer tube 41, the distance between the end of the heating network tube 422 away from the air inlet end and the end of the ceramic tubular liquid-conducting substrate 421 away from the air inlet end is L1, the distance between the end of the heating network tube 422 close to the air inlet end and the end of the ceramic tubular liquid-conducting substrate 421 close to the air inlet end is L2, and the length of the heating network tube 422 is L0. When L0>L1, L0>L2, L0≥L1+L2, the height of the heating network tube 422 can be set at a suitable position of the heating network tube 422, so as to ensure sufficient atomization effect, neither smoke sticking nor making the atomized liquid fully atomized, so as to achieve the best atomization effect and suction taste.

[0046] In some embodiments, the atomizer further comprises:

[0047] A blocking tube 3, inserted into the airway tube 2, for blocking the liquid inlet hole 21;

[0048] When the atomizing assembly is inserted into the airway tube 2 via the air inlet end of the airway tube 2 , the blocking tube 3 can be forced to be misaligned with the liquid inlet hole 21 to open the liquid inlet hole 21 .

[0049] The tubular heating module 42 may specifically be a ceramic core tubular heating module 42 .

[0050] In this embodiment, an airway tube 2 is provided in the liquid storage cup assembly, both ends of which are connected to the outside. The airway tube 2 is provided with a liquid inlet hole 21 that allows the inside of the airway tube 2 to communicate with the liquid storage chamber of the liquid storage cup assembly, and the liquid storage chamber stores atomized liquid;

[0051] The blocking tube 3 is inserted into the airway tube 2 to block the liquid inlet hole 21;

[0052] When the atomizer assembly is inserted into the airway tube 2 via the air inlet end of the airway tube 2, the atomizer assembly forces the blocking tube 3 to be misaligned with the liquid inlet hole 21, and the liquid inlet hole 21 can be opened. Therefore, during transportation or before use, the atomizer assembly and the liquid storage cup assembly are independent of each other. Since the blocking tube 3 is inserted into the airway tube 2, the liquid inlet hole 21 can be blocked. Therefore, the atomizer assembly can be prevented from being immersed in the liquid storage cup assembly for a long time, which may cause the atomizer liquid to spoil and the atomizer assembly to oxidize, thereby affecting the taste and changing taste. It also solves the problem in the related art that the atomizer assembly and the liquid storage cup assembly are not completely sealed, resulting in easy leakage, thereby improving the reliability of the product.

[0053] When it is needed, the atomizing assembly can be inserted into the airway tube 2 through the air inlet end of the airway tube 2, forcing the blocking tube 3 to be misaligned with the liquid inlet hole 21, so that the liquid inlet hole 21 can be opened.

[0054] In some embodiments, the blocking tube 3 is provided with two annular grooves 31 spaced apart and extending in the circumferential direction, each of the annular grooves 31 is provided with a first sealing ring 32, and the first sealing ring 32 is sealed with the bottom of the annular groove 31 and the inner wall of the airway tube 2. When the blocking tube 3 blocks the liquid inlet hole 21, the two first sealing rings 32 are located on both radial sides of the liquid inlet hole 21, thereby ensuring the sealing effect of the blocking tube 3 and preventing liquid leakage.

[0055] In some embodiments, the liquid storage cup assembly includes a cup body 11 and a sealing piece 12, the cup body 11 is constructed with an air outlet pipe 111 connected to the outside, the sealing piece 12 is arranged at the mouth of the cup body 11 away from the air outlet pipe 111, the air outlet end of the airway tube 2 is connected to the air outlet pipe 111, the air inlet end is inserted on the sealing piece 12, and passes through the sealing piece 12 in a direction away from the air outlet end to form an atomization airflow channel.

[0056] In some embodiments, a bottom cover 33 is fastened at one end of the cup body 11 away from the air outlet pipe 111, and the blocking member 12 is arranged inside the bottom cover 33. The bottom cover 33 is provided with an insertion hole adapted to the atomization assembly, so that the bottom cover 33 prevents the blocking member 12 from falling and causing leakage.

[0057] In some embodiments, a sealing plug 34 is sleeved on the end of the air outlet pipe 111, and the inner wall of the sealing plug 34 is constructed with at least one first annular protrusion 341 extending circumferentially and sealingly matched with the outer wall of the air outlet pipe 111, and the end of the sealing plug 34 away from the air outlet pipe 111 is constructed with a first annular groove 342, and the air outlet end is inserted in the first annular groove 342. The sealing plug 34 of this embodiment can improve the sealing effect of the connection between the air outlet pipe 111 and the airway tube 2 to prevent liquid leakage.

[0058] In some embodiments, the atomization assembly includes an atomization tube 41 and a tubular heating module 42. The atomization tube 41 is provided with a liquid passage hole 411 arranged opposite to the liquid inlet hole 21. The tubular heating module 42 is arranged in the atomization tube 41 at a position opposite to the liquid passage hole 411, so that the tubular heating module 42 can heat the atomized liquid entering the atomization tube 41.

[0059] In some embodiments, the atomization assembly also includes an atomization base 43 connected to one end of the atomization tube 41 away from the blocking tube 3, and an insulating ring 45 is provided at the end of the atomization base 43 away from the atomization tube 41. The insulating ring 45 is provided with at least two first electrodes 44 connected to the tubular heating module 42. The two first electrodes 44 are specifically electrically connected to the heating mesh tube 422 of the tubular heating module 42, and the insulating ring 45 is used to prevent the first electrode 44 from leaking electricity.

[0060] In some embodiments, the outer periphery of the atomizer base 43 and the outer periphery of the atomizer tube 41 are both provided with a second annular groove, and a second sealing ring 412 is provided in each of the two second annular grooves. When the atomizer assembly is inserted into the airway tube 2, the two second sealing rings 412 are located on both radial sides of the liquid inlet hole 21, and the second sealing ring 412 is used to improve the sealing effect between the atomizer assembly and the inner wall of the airway tube 2.
