Referring to fig. 1 to 3, an embodiment of the present application provides an atomizer, which includes a first liquid guiding member 1, a second liquid guiding member 2, a heat generating member 3, a liquid storage chamber 4, and a shielding member 5. First drain 1 is arranged in sealed stock solution storehouse 4 to absorb and conduct the atomized liquid in the stock solution storehouse, first drain 1 is connected to second drain 2, in order to follow first drain 1 and absorb the atomized liquid, and piece 3 that generates heat is located second drain 2, in order to lead the atomized liquid on the liquid 2 through piece 3 that generates heat heating, make it atomize. The shielding member 5 is used for preventing the atomized liquid on at least part of the exposed area 121 in the first liquid guiding member 1 from volatilizing.

In some embodiments, the first liquid guiding member 1 is a porous fiber in a sheet or block shape, and the main component of the porous fiber is polymer cotton, and can be hard artificial cotton containing polyester fiber, or hard synthetic cotton or artificial foam containing filamentous polyurethane, etc., the first liquid guiding member 1 generally has hardness or flexibility between that of flexible plant cotton/non-woven fabric and that of rigid porous ceramic/microporous metal, for example, in some examples, first fluid conducting element 1 has a shore hardness of between 20A and 80A, and is therefore structurally stable, after absorbing and infiltrating atomized liquid, the liquid guide member has extremely low swelling, and the contact between the first liquid guide member 1 and the inner wall of the shell 6 after assembly is the contact between flexible contact and rigid contact, so that the first liquid guide member 1 can independently seal the liquid storage bin 4 by utilizing the flexibility of the first liquid guide member 1, and the first liquid guide member has certain hardness and can be easily fixed and held by the shell 6. In particular, according to what is shown in the above figures, the shape of the first liquid guiding member 1 is substantially adapted to the opening at the lower end of the liquid storage compartment 4, and can then be used to cover, seal and seal the liquid storage compartment 4. In other examples, the first liquid guiding element 1 has a Shore hardness of 50-70A, which is approximately equivalent to a hardness of a thermoplastic elastomer or a silicon rubber at a considerable level.

Referring to fig. 1, the first liquid guiding member 1 has a substantially elliptical or elliptical-like shape, and thus has an elliptical or elliptical-like cross section, and the opening at the lower end of the reservoir 4 has an elliptical shape. The first fluid-conducting member 1 is made of oriented fibres, such as polyethylene and/or polypropylene, which are oriented substantially in the longitudinal direction, i.e. the plurality of fibre bundles in the first fluid-conducting member 1 extend substantially aligned in the same direction, e.g. substantially perpendicular to the thickness direction of the first fluid-conducting member 1. It can be understood that the fiber material with the same orientation can improve the bending strength of the first liquid guiding member 1 on one hand, and can control the liquid transmission rate to a reasonable range by permeating and transmitting the liquid from one side to the other side of the first liquid guiding member 1 in the thickness direction in terms of the liquid transmission direction on the other hand, so that the liquid transmission rate is prevented from being too fast.

The oriented fibers are arranged in the length direction of the first liquid guide member 1, so that the first liquid guide member 1 has the characteristic of high bending strength and hardness. And the first liquid guide member 1 prepared by adopting the organic fibers can keep sufficient gaps among fiber materials in the preparation process, so that atomized liquid can be transmitted, and the first liquid guide member has proper flexibility. In some examples, the first fluid-conducting member 1 having the above-oriented fibers is anisotropic. On one hand, the bending strength at least along the length direction is larger than that along the width direction; or on the other hand, has a drainage rate in the length direction that is greater than the drainage rate in the width direction.

In another embodiment, the length L of the first liquid guiding member 1 in the major axis direction (length direction) may be 16.4mm, the length W in the minor axis direction (width direction) may be 7.6. + -. 0.01mm, and the thickness of the first liquid guiding member 1 may be 2. + -. 0.1 mm.

In cooperation with the above-mentioned features of the first liquid guiding member 1, the density of the fiber material in the first liquid guiding member 1 is greater than the density of the fiber material in the second liquid guiding member 2. For example, in some examples, the first liquid-guiding component 1 has a density of 0.26mg/mm in a state of not absorbing atomized liquid ³ To 0.31mg/mm ³ In between, e.g., 0.2850.15mg/mm ³ To ensure that the speed of the first liquid guiding part 1 for absorbing and transferring the atomized liquid meets the requirement of consuming the atomized liquid to generate a proper amount of aerosol, and ensure the supplyOil balance, avoid the appearance of fried oil.

The second liquid guiding part 2 is a carrier of the heating part 3 and is mainly used for transferring the atomized liquid adsorbed from the first liquid guiding part 1 to the position of the heating part 3 so as to heat the heating part 3 to volatilize the atomized liquid.

The second liquid guiding member 2 may be flexible, e.g. may be made of a flexible strip or rod-like fibrous material, such as cotton fibers, nonwoven fibers, sponge or the like, having a stiffness which is less than that of the first liquid guiding member 1. The second liquid guiding member 2 can also be made of the same material as the first liquid guiding member 1, and has hardness or flexibility between a common flexible plant cotton/non-woven fabric (shore hardness is less than 20A) and a rigid porous ceramic/microporous metal (shore hardness is greater than 80A), so that the structure is stable, the swelling is extremely low after the atomization liquid is absorbed and soaked, and the contact between the second liquid guiding member 2 and the inner wall of the atomization cup 7 after the assembly is the contact between the flexible contact and the rigid contact, so that the second liquid guiding member can be easily fixed and held by the atomization cup 7 due to certain hardness.

The heating wires 31 may be all nickel wires, or may be heating wires 31 made of other materials that can generate heat when energized. In an alternative, when the heating element 3 includes the parallel dual electric heating wires 31, the wire diameter of each electric heating wire 31 is smaller than 0.16mm (0.16-0.25 mm of the conventional electric heating wire), and the wire diameter of the electric heating wire described in this embodiment is smaller than that of the conventional electric heating wire, so that the outer surface of each electric heating wire 31 in this embodiment can be fully contacted with the atomized liquid on the connection portion (the local outer surface of the electric heating wire with the larger wire diameter may not be immersed by the atomized liquid on the connection portion due to being far away from the liquid guide element, and thus cannot be fully contacted with the atomized liquid), so that the atomized liquid on the connection portion can be uniformly heated, and oil frying due to the over-high local temperature cannot occur. In a further version of this embodiment, the wire diameter of each heating wire is 0.12 mm.

In some embodiments, the heating wire 31 has lead wires 32 at both ends thereof, the lead wires 32 are made of thick wires with respect to the heating wire 31, and the diameter of the lead wires 2 is about 0.13-0.3 mm, and in this embodiment, the diameter of the lead wires 32 may be about 0.25 mm.

To this end, in an embodiment of the present application, the shielding member 5 is disposed to cover at least a part of the exposed area 121 by contacting the shielding member 5 with the exposed area 121, and the evaporation of the atomized liquid on the exposed area 121 is blocked by influencing the airflow on the exposed area 121.

In the embodiment shown with reference to fig. 2 and 5, the side wall of the atomizing cup 7 is provided with a stopper 71, and the stopper 61 is configured to interfere with the side edge of the supporting portion 52, thereby stopping the side edge of the supporting portion 52 in the lateral direction and preventing the shutter 5 from shaking in the lateral direction. In the embodiment as shown in fig. 2, 4 and 5, the number of the support portions 52 is at least two, including the first support portion 521 and the second support portion 522, and the support portions 52 have elasticity or the support portions 52 are elastically connected to the shielding portion 51, so that the distance between the shielding portion 51 and at least the first support portion 521 and the second support portion 522 can be elastically increased or elastically reduced, and at least two stopping portions 71 are provided on the sidewall of the atomizing cup 7 corresponding to the number and positions of the support portions 52, and are arranged along the length direction in the transverse direction, including the first stopping portion 711 and the second stopping portion 712, each stopping portion 71 stops one support portion 52, the first stopping portion 711 stops the first support portion 521 transversely, and the second stopping portion 712 stops the second support portion 522 transversely, of course, the stopping may be an elastic stopping portion, and may also be a rigid stopping portion.

The above-described elastic contractive force or elastic expansive force acts on the first stopper 711 and the second stopper 712 of the atomizing cup 7, so that the shutter 5 can be stably fixed by the atomizing cup 7 and can also be prevented from wobbling in the lateral longitudinal direction. In the embodiment shown with reference to fig. 3 and 4, the shielding portion 51 is sheet-shaped, and has a larger area and a smaller weight, and the larger area of the shielding portion 51 enables the shielding portion 51 to contact more exposed areas 121, so as to prevent the atomized liquid and the components thereof on the exposed areas 121 from volatilizing to a greater extent; the support portion 52 is sheet-shaped, so that it can have a larger amount of elastic deformation while also having a smaller weight. Of course, in other embodiments, the shielding portion 51 and the supporting portion 52 may have other shapes and weights.
