Further, the present application also provides a second embodiment, referring to fig. 11, which is different from the above-mentioned example, that the main body portion 211 of the liquid guiding element 21 is arranged obliquely downward, the included angle between the first capillary element 24 and the main body portion 211 of the liquid guiding element 21 is an obtuse angle, and the included angle between the second capillary element and the main body portion 211 is an acute angle; the included angle between the main body portion 211 and the first extending portion 212 is an acute angle, and the included angle between the main body portion 211 and the second extending portion 213 is an obtuse angle. Since the main body portion 211 of the liquid guiding member 21 is disposed obliquely downward, the excess liquid matrix transferred to the liquid absorbing member 21 by the first capillary element 24 can be directly introduced into the second extending portion 213 in the direction of gravity, and the liquid conducting ability of the extending portion 213 located below the main body portion 211 is further optimized so that the region of the liquid guiding member 21 where the heat generating element 22 is fixed does not accumulate excess liquid matrix. Meanwhile, the fixed ends of the first and second support arms 423 and 424 for fixing the liquid guide member 21 are disposed to be staggered, and particularly, the fixed end of the second support arm 424 is located below the fixed end of the first support arm 423. And the length of the second capillary element 25 is greater than that of the first capillary element 24, so that the main body part 211 can be just obliquely fixed on the bracket 40, and two sides of the main body part are respectively contacted with the first capillary element 24 and the second capillary element 25.
Further, the present application also provides a third embodiment, referring to fig. 12, different from the second embodiment provided in the present application, only one liquid guiding hole 311 is provided on the sealing member 30, the first capillary element 24 is fixedly provided in the liquid guiding hole 311, and the first capillary element 24 is in contact with the end of the main body portion 211 of the liquid guiding element 21. The first capillary element 24 is connected to the left end of the main body part 211, the right end of the main body part 211 is provided with a second extending part 213, no separate capillary element is arranged above the second extending part 213 to be connected with the main body part 211, and the second extending part 213 further extends to the inside of the second containing cavity 463 towards the direction away from the liquid storage cavity 14; understandably, when the fluidity of the liquid medium is good, a capillary element 24 can also satisfy the requirement of the liquid transfer rate of the liquid guiding element 21, and at the same time, only an extension 213 needs to be provided on the other side to temporarily lead out the excess liquid medium of the main body portion 211.
Understandably, different numbers of capillary elements 23 may be matched depending on the specific atomization efficiency of the heat-generating element 22 of the atomizer 100 and the flow properties of different liquid substrates; meanwhile, different numbers or lengths of the extending parts 212 are arranged below the main body part 211 of the liquid guide element 21, and since the extending parts 212 are arranged below the main body part 211, the liquid matrix is influenced by the action of gravity and is conducted to the tail ends of the extending parts 212, and meanwhile, the main body part 211 can absorb enough liquid matrix without causing excessive liquid matrix accumulation in a heat generating area. Further, if extension 212 accumulates an excessive amount of liquid matrix, the liquid matrix may be further buffered inside first accommodation chamber 462 or second accommodation chamber 463. As the heat generating element 22 atomizes the liquid matrix of the main body portion 211 of the liquid guiding element 21, the liquid matrix buffered inside the extension portion 212 and/or the first accommodating chamber 462 and/or the second accommodating chamber 463 can be transferred to the main body portion 211 for the first time, so that the atomization rate and the liquid transfer rate are balanced.
Referring to fig. 13 and 14, the bracket 40 is provided with an air inlet 70 for allowing outside air to enter the inside of the atomizer 100, and the air inlet 70 penetrates the end cover 41 and extends at least partially along the longitudinal direction of the housing 10. The bottom surface of the supporting part 42 of the bracket 40 is provided with a vent hole 71, the vent hole 71 is arranged right opposite to the heating element 22, and the air outlet end of the vent hole 71 is arranged higher than the surrounding plane to form a raised structure, so that condensate formed when the inside of the atomizing cavity 23 is cooled is difficult to overflow from the vent hole 71. Further, extending downwards along the longitudinal direction of the vent hole 71, a part of the wall surface of the supporting portion 42 of the bracket 40 is disposed to protrude downwards to form a shielding portion 47, and the shielding portion 47 is located above the air outlet end of the air inlet 70, so that a part of the liquid medium overflowing from the vent hole 71 cannot enter the air inlet 70. Meanwhile, in order to facilitate the external air output from the air inlet 70 to enter the vent hole 71, the end surface of the shielding portion 47 is provided with a V-shaped diversion slope 471, the external air flow enters a second air guide hole 72 located on the left side of the vent hole 71 along the diversion slope 471, and the second air guide hole 72 is communicated with the vent hole 71. And the second air-guide hole 72 is completely separated from the air inlet 70 by a portion of the wall surface inside the bracket 40, the leaked liquid cannot enter the air inlet 70 through the second air-guide hole 72. The outside air passes through the air inlet 70, bypasses into the second air guide hole 72, then enters the air vent hole 71, and further enters the atomization chamber 23.
The lower end of the atomizing chamber 23 is communicated with the vent hole 71, the upper end is communicated with the vent pipe 13, and the whole space is defined by the bracket 40 and the sealing element 30 together to form a closed space for flowing only one-way airflow, so that the liquid matrix can be prevented from leaking from the outlet of the atomizing chamber 23 to the maximum extent. In order to further improve the sealing performance of the whole atomizer 1200, referring to fig. 15, the surrounding wall 32 of the sealing member 30 substantially covers the outer surface of the supporting portion 42 of the bracket 40 and extends downward to the upper end of the fixing buckle 431 of the bracket 40 and the housing 10, and two layers of sealing flanges 36 are arranged at the lower end of the surrounding wall 32 so as to further form a tight fit with the inner wall surface of the housing 10 and prevent liquid from leaking downward from the gap between the surrounding wall 32 of the sealing member 30 and the housing 10.
Referring to fig. 40, the end cap 41 is provided with positive and negative electrode posts 50 penetrating therethrough, the positive and negative electrode posts being located at both sides of the air inlet 70, the positive and negative electrode posts 50 being connected to both ends of the heating element 22 by wires. Specifically, wire holes 51 for fixing wires are further provided on the bottom end face of the support portion 42 of the bracket 40, and the positive and negative wire holes 51 extend longitudinally along the casing 10 to the fixed ends of the positive and negative electrode posts 50 so as to facilitate connection of the wires with the positive and negative electrode posts 70.
