[0034] like Figure 1As shown, in one embodiment, an atomizer assembly 100 is provided, which relates to the technical field of atomizer devices. The atomizer assembly 100 includes a liquid guide 110, a heating wire 120, a first lead 130 and a second lead 140.

[0035] The heating wire 120 is spirally wound around the outer surface of the liquid guide 110. The first lead 130 is partially spirally wound around the outer surface of the liquid guide 110 and connected to one end of the heating wire 120. The second lead 140 is partially spirally wound around the outer surface of the liquid guide 110 and connected to the end of the heating wire 120 away from the first lead 130.

[0036] The atomizer assembly 100 provided in the embodiment of the present application is configured such that a portion of the first lead 130 is spirally wound around the outer surface of the liquid guide 110 and connected to one end of the heating wire 120, and a portion of the second lead 140 is spirally wound around the outer surface of the liquid guide 110 and connected to the end of the heating wire 120 away from the first lead 130. In this way, a portion of the first lead 130, the heating wire 120, and a portion of the second lead 140 define a coil spirally wound around the outer surface of the liquid guide 110, and a portion of the first lead 130 and a portion of the second lead 140 act as the outermost turns of the coil to bear stress release and expansion, thereby preventing the heating wire from being separated from the liquid guide due to stress release and expansion, which could cause the heating wire to partially dry-burn and generate harmful substances that could be inhaled by the human body and cause harm to the human body.

[0037] It should be noted that the heating wire 120 is made of a different material from the first lead 130 and the second lead 140, and the resistivity of the heating wire 120 is higher than that of the first lead 130 and the second lead 140, so as to realize the function of generating heat after the heating wire 120 is energized, and realize the conductive function of the first lead 130 and the second lead 140. In this way, even if part of the first lead 130 and part of the second lead 140 are subjected to stress release and expansion and are out of contact with the liquid guide part 110, they will not dry burn and generate harmful substances.

[0038] At the same time, since the heating wire 120 and the first lead 130 and the second lead 140 are made of different materials, the connection between the heating wire 120 and the first lead 130 and the second lead 140 can be welding, and the welding position is where the heat is concentrated, there is a potential risk of dry burning. Therefore, by partially spirally winding the first lead 130 around the outer surface of the liquid guide 110 and welding it to one end of the heating wire 120, and partially spirally winding the second lead 140 around the outer surface of the liquid guide 110 and welding it to the end of the heating wire 120 away from the first lead 130, the welding point between the first lead 130 and the heating wire 120 and the welding point between the second lead 140 and the heating wire 120 are both located on the coil, thereby ensuring good contact between the welding point and the liquid guide 110 and reducing the risk of dry burning of the welding point to generate harmful substances.

[0039] For example, the material of the heating wire 120 can be a metal material with high resistivity such as nickel-chromium, iron-chromium, iron-chromium-aluminum, stainless steel, etc., and the material of the first lead 130 and the second lead 140 can both be a metal material with low resistivity such as nickel, copper, aluminum and its alloys, and the welding method can be electric welding or laser welding.

[0040] In addition, the material of the liquid guiding part 110 can be organic cotton. Since part of the first lead 130 and part of the second lead 140 are the outermost turns of the coil to bear stress release and expansion, the heating wire 120 is prevented from being out of contact with the liquid guiding part 110 due to stress release and expansion, so that the heating wire 120 and the liquid guiding part 110 have good contact, so that the liquid guiding part 110 does not need to add more organic cotton to ensure the contact performance between the heating wire 120 and the liquid guiding part 110, thereby avoiding the technical problem of the liquid guiding part 110 being too tight and causing the liquid to be not smooth.

[0041] In one embodiment, the diameter of the heating wire 120 is D1, and the diameters of the first lead 130 and the second lead 140 are both D2, satisfying the relationship: -0.2≤(D1-D2) / D1≤0.2.

[0042] In this embodiment, by controlling the ratio of the difference in diameter between the heating wire 120 and the first lead 130 / the second lead 140 to the diameter of the heating wire 120 within the range of -0.2 to 0.2, the diameter difference between the heating wire 120 and the first lead 130 and the second lead 140 is within 20%, thereby avoiding the technical problem of the heating wire 120 being bulged due to the large diameter difference after being welded to the first lead and the second lead and spirally wound, thereby affecting the contact between the heating wire and the liquid guide member.

[0043] For example, the ratio of the difference in diameter between the heating wire 120 and the first lead 130 / the second lead 140 to the diameter of the heating wire 120 can be -0.2, -0.1, -0.05, 0, 0.05, 0.1, 0.2, etc., that is, the diameter difference between the heating wire 120 and the first lead 130 and the second lead 140 can be 0, 5%, 10%, 20%, etc., and can be specifically designed according to the actual needs of the product, and will not be listed here one by one.

[0044] In one embodiment, the number of turns of the first lead 130 and the second lead 140 spirally wound around the outer surface of the liquid-guiding member 110 is N1, which satisfies the following: 0.5≤N1<1.

[0045] In this embodiment, by controlling the number of turns N1 of the first lead 130 and the second lead 140 spirally wound around the outer surface of the liquid guide member 110 to be within the range of 0.5 to 1 turn, that is, more than half a turn and less than one turn, this can ensure the contact effect between the heating wire 120 and the liquid guide member 110, and avoid the technical problem that the heating wire is also affected by stress release and expansion, causing the heating wire to lose contact with the liquid guide member due to too few turns of the first lead and the second lead being spirally wound around the liquid guide member. On the other hand, it can also ensure the heating effect of the heating wire 120, and avoid the technical problem that the heating wire is spirally wound around the liquid guide member too many times, resulting in too few turns of the heating wire being spirally wound around the liquid guide member, thereby affecting the heating effect of the heating wire.

[0046] For example, the number of turns N1 of the first lead 130 and the second lead 140 spirally wound around the outer surface of the liquid guide 110 can be 0.5, 0.7, 0.8, 0.9, etc., which can be specifically designed according to the actual needs of the product and will not be listed here one by one.

[0047] In one embodiment, the number of turns of the heating wire 120 spirally wound around the outer surface of the liquid-guiding member 110 is N2 turns, satisfying the relationship: 2≤2N1+N2≤10.

[0048] In this embodiment, the number of turns N1 of the first lead 130 and the second lead 140 spirally wound on the outer surface of the liquid guide 110 is controlled to be within the range of 0.5 to 1 turn, and the sum of the number of turns of the heating wire 120, the first lead 130 and the second lead 140 spirally wound on the outer surface of the liquid guide 110 is controlled to be within the range of 2 to 10 turns. In this way, on the one hand, the heating effect of the heating wire 120 can be guaranteed, and the technical problem of the heating effect of the heating wire being affected by too few turns of the heating wire spirally wound on the liquid guide can be avoided. On the other hand, the contact effect between the heating wire 120 and the liquid guide can be guaranteed, and the technical problem of the contact effect between the heating wire and the liquid guide can be avoided by too many turns of the heating wire spirally wound on the liquid guide.

[0049] For example, the sum of the number of turns of the heating wire 120, the first lead 130 and the second lead 140 spirally wound on the outer surface of the liquid guide 110 can be 2, 4, 5, 6, 8, 10, etc., which can be specifically designed according to the actual needs of the product and will not be listed here one by one.

[0050] like Figure 1 As shown, in one embodiment, the length of the liquid guide 110 is L, which satisfies: 10 mm ≤ L ≤ 50 mm.

[0051] In this embodiment, by controlling the length L of the liquid guide 110 within the range of 10 mm to 50 mm, the liquid storage capacity of the liquid guide 110 is ensured, so that the liquid is adequately supplied to the heating wire 120, thereby avoiding the technical problem of insufficient liquid supply due to a short liquid guide and thus failing to meet user needs. Furthermore, the liquid guide 110 ensures smooth liquid flow, thereby avoiding the technical problem of excessive compression of the liquid guide and resulting in poor liquid flow due to an excessively long liquid guide.

[0052] Exemplarily, the length L of the liquid guide 110 can be 10 mm, 15 mm, 20 mm, 30 mm, 35 mm, 40 mm, 50 mm, etc., and can be specifically designed according to the actual needs of the product, which will not be listed here one by one.

[0054] In this embodiment, two through holes 153 communicating with the tubular cavity 151 are opened on the side wall of the tube body 150, and the heating wire 120 and the liquid guiding member 110 are arranged in the tubular cavity 151, and the two ends of the liquid guiding member 110 are respectively arranged outside the tubular cavity 151 through different through holes 153. In this way, the liquid outside the tubular cavity 151 can be continuously supplied to the heating wire 120 in the tubular cavity 151 through the liquid guiding member 110, and is heated by the heating wire 120 to generate an atomized aerosol product for the user to inhale.

[0055] Exemplarily, the tube body 150 may be a glass fiber tube, and the lumen 151 of the glass fiber tube is an atomization chamber.

[0056] like Figure 2 and Figure 3 As shown, in one embodiment, the atomizer assembly 100 further includes a liquid storage member 160 . The liquid storage member 160 is sleeved on the outer circumferential wall of the tube body 150 and abuts against the liquid guide member 110 .

[0057] In this embodiment, the liquid storage member 160 is sleeved on the outer circumferential wall of the tube body 150 and abuts against the liquid guiding member 110. In this way, the liquid stored in the liquid storage member 160 can be continuously supplied to the heating wire 120 in the tube cavity 151 through the liquid guiding member 110, and is heated by the heating wire 120 to generate an atomized aerosol product for the user to inhale.

[0058] Exemplarily, the material of the liquid storage member 160 may be organic cotton.

[0059] like Figure 2 and Figure 3 As shown, in one embodiment, the atomizer assembly 100 further includes a liquid storage container 170, a first sealing member 180 and a second sealing member 190, wherein the first sealing member 180 and the second sealing member 190 are respectively disposed at both ends of the liquid storage container 170, the tube body 150 is disposed in the liquid storage container 170 and abuts against the first sealing member 180 and the second sealing member 190 respectively to enclose and form a liquid storage space 171, and the end of the tube body 150 away from the first opening 152 has a second opening communicating with the tube cavity 151 154, the first sealing member 180 is provided with a first through hole 181 communicating with the first opening 152, the second sealing member 190 is provided with a second through hole 191 communicating with the second opening 154, the first lead 130 and the second lead 140 are both located in the tube cavity 151 at one end close to the heating wire 120, and the first lead 130 and the second lead 140 are both located in the tube cavity 151 at one end away from the heating wire 120 and are sequentially passed through the first opening 152 and the first through hole 181 and are arranged outside the liquid storage space 171.

[0060] In this embodiment, a first seal 180 and a second seal 190 are provided at each end of a liquid storage container 170, and a tube 150 is disposed within the liquid storage container 170 and abuts against the first and second seals 180, 190.

The tube 150 has a second opening 154 communicating with the lumen 151 at one end distal from the first opening 152.

This connects the two ends of the lumen 151 to the outside world and the user's inhalation end, respectively. This allows ambient air to enter the lumen 151 and mix with the generated aerosol to form an aerosol product for inhalation by the user.
