Referring to fig. 1 and fig. 2, a schematic diagram of an electronic atomizer according to a preferred embodiment of the present invention is shown. The electronic atomization device comprises a shell 1, a base 2 and an atomization core 3. The shell 1 is provided with an opening 13 at one end and a suction port 14 at the other end. One end of the shell 1 provided with the opening 13 covers the base 2 to enclose the oil storage cavity 4. The atomizing core 3 has one end fastened to the base 2 and the other end connected to the suction port 14. The housing 1 is of a unitary construction comprising a transparent outer layer 11 and a non-transparent inner layer 12, the outer layer 11 only partially overlapping the inner layer 12 to form a viewing window 5. The inner wall cladding of shell 1 has transparent oil removal layer 6 to isolated the fluid in the oil storage chamber 4 with shell 1. The window 5 is formed through the overlapping difference between the inner layer 12 and the outer layer 11 of the shell 1 to the embodiment, so that a user can observe the residual liquid level conveniently, and meanwhile, the oil separation layer 6 is adopted to isolate oil liquid from the shell 1, so that the shell 1 is prevented from being corroded.

In the present embodiment, as shown in fig. 1, the atomizing core 3 may include a heat generating member 32, an oil guiding member (not shown), and a sleeve 31. The heating member 32 is a hollow cylindrical structure formed by winding a heating wire or a heating net. The oil guide member is sleeved on the periphery of the heating member 32, can also penetrate through a hollow part formed by winding the heating member 32, can be made of oil guide cotton and/or porous ceramic materials, and can be connected with the heating member 32 in a split manner or integrally formed. The sleeve 31 is sleeved on the periphery of the oil guide to provide protection and support. One end of the sleeve 31 is tightly inserted into the base 2, and the other end is connected to the suction port 14, so that an atomizing channel independent of the oil storage chamber 4 is formed in the oil storage chamber 4, and the heating element 32 and the oil guide element are both located in the atomizing channel. Correspondingly, the sleeve 31 is provided with an oil guide hole for communicating the atomizing channel with the oil storage chamber 4, and the oil guide member is exposed from the oil guide hole to the oil storage chamber 4, so that the oil in the oil storage chamber 4 can be absorbed by the oil guide member via the oil guide hole, and the oil is heated by the heat generating member 32 and atomized into aerosol, and finally flows out of the electronic atomization device 100 via the atomizing channel and the suction port 14.

In the present embodiment, the outer layer 11 and the inner layer 12 are formed by a two-shot molding process to form the housing 1 of an integral structure. Namely, two plastic materials are injected on the same injection molding machine and are molded twice, so that the shell 1 is only demoulded once, the processing mode has high efficiency, and the aesthetic property, the assembly performance and other performances of the product can be improved. After molding, the outer layer 11 covers the outer surface of the inner layer 12, whereas the inner layer 12 covers the inner surface of the outer layer 11. The outer layer 11 is made of transparent material, and may be completely transparent or translucent, and may have a suitable transparency according to actual requirements. The inner layer 12 is made of a non-transparent material, and the color thereof can be selected according to actual requirements, for example, pure color or color can be selected, and different patterns or patterns can be formed by matching colors. The material selected for the outer layer 11 and the material selected for the inner layer 12 must have a melting point difference, preferably, the melting point difference is 30-60 ℃. Wherein the non-transparent material has a melting point higher than that of the transparent material. For example, the inner layer 12 may be made of non-transparent PC with a higher melting point, and the outer layer 11 may be made of PMMA (polymethyl methacrylate), which is also called acrylic or organic glass, or PC with a lower melting point. It is worth mentioning that the material of the outer layer 11 may be a hard material, such as PMMA, which may exhibit a transparent effect; it may also be a soft material, such as TPU (Thermoplastic polyurethane elastomers), which may exhibit a frosted transparent texture, and the soft rubber may buffer external impacts, playing a protective role. Of course, in practical applications, the outer layer 11 and the inner layer 12 may also be formed by other integrally forming processes to form the housing 1 with an integral structure.

Further, as shown in fig. 2, the outer layer 11 only partially overlaps the inner layer 12, i.e. the outer shell 1 comprises a single-layer portion and a double-layer portion. The single layer portion is composed only of the outer layer 11, and the double layer portion is formed by overlapping the outer layer 11 and the inner layer 12. Since the outer layer 11 is made of transparent material, the portion of the outer layer 11 not overlapping the inner layer 12 (i.e. the single-layer portion of the outer shell 1) forms a transparent window 5. The user can observe the oil use condition and the oil allowance in the oil storage chamber 4 through the window 5. Preferably, the thickness of the single-layer part and the double-layer part of the housing 1 is the same, so that the thickness of each part of the housing 1 is the same, and thus, the situation that the strength of the housing 1 is affected by the shrinkage of the housing 1 in the molding process or the stress concentration easily generated in the later use process can be avoided.

Preferably, the inner layer 12 is wrapped around the outer layer 11 near the base 2 in a cylindrical structure, so that the outer layer 11 near the suction opening 14 is not wrapped to form a cylindrical window 5. The uncoated part of the outer layer 11 (the window 5) extends away from the base 2 and forms the suction opening 14. Only wrap the part that outer layer 11 is close to base 2 through inlayer 12 for outer layer 11 is close to the part of suction opening 14 and all can form transparent window 5, makes window 5 complete and area big, and convenience of customers looks over fluid.

In some embodiments of the present invention, because the surface area of the inner layer 12 is smaller than the surface area of the outer layer 11, the inner layer 12 may form a predetermined pattern on the inner surface of the outer layer 11, such that the viewing window 5 may appear correspondingly abrupt. For example, the pattern may be a geometric pattern, a text pattern, a decorative pattern, an animal pattern, or the like. So that the user can observe the oil through the window 5 having a specific pattern.

In this embodiment, as shown in fig. 1, the oil-separating layer 6 has a shape matching the shape of the housing 1, an outer wall of the oil-separating layer fits the inner wall of the housing 1, and one end of the oil-separating layer is hermetically inserted into the base 2, and the other end of the oil-separating layer is hermetically inserted into the suction port 14. When the atomizing device is installed, the atomizing core 3 can be firstly inserted into the base 2, and then the oil separation layer 6 is sleeved on the periphery of the base 2, and the atomizing core 3 is inserted into the other end of the oil separation layer 6. Then the atomizing core 3, the base 2 and the oil separating layer 6 are assembled into a whole body and put into the opening from the opening end of the shell 1 until the other end of the oil separating layer 6 is inserted into the suction port 14. In practical application, the oil-separating layer 6 is made of a material resistant to oil corrosion. Preferably, the material resistant to corrosion of the oil solution is PCTG (polyethylene terephthalate-1, 4-cyclohexanedimethanol). The PCTG can resist various chemicals and common cleaning agents, has a stable structure and is not easy to corrode by oil. Meanwhile, PCTG has excellent weather resistance, which can maintain the toughness of the housing 1 and prevent yellowing. This embodiment isolates fluid and shell 1 through setting up transparent oil removal layer 6, can reduce the requirement to the 1 material of shell like this to shell 1 inlayer 12 and outer 11 need not to choose for use resistant oily liquid corrosive material, have increased the selected range of shell 1 material, are favorable to reduction in production cost. It is worth mentioning that the oil-separating layer 6 and the housing 1 are both made of non-toxic food grade materials in contact with the oil or the user.

Preferably, a first seal 61 is interposed between the oil-barrier layer 6 and the inner wall of the suction port 14. A first installation groove matched with the first sealing ring 61 can be arranged on the periphery of the oil separation layer 6 or on the inner wall of the suction port 14, and the first sealing ring 61 is partially embedded into the first installation groove to limit the first sealing ring 61, so that the first sealing ring 61 is prevented from being displaced relative to the oil separation layer 6 or the shell 1, and sealing failure is caused.

Further, a second seal ring 62 is interposed between the oil-barrier layer 6 and the inner layer 12 and/or the outer layer 11. The second sealing ring 62 may be located in a single layer portion of the housing 1 or in a double layer portion of the housing 1. Preferably, the second sealing ring 62 is located in a double-layer portion of the housing 1, so that the second sealing ring 62 can be covered by the inner layer 12, and the second sealing ring 62 cannot be seen through the window 5 by a user, which is beneficial to maintaining the aesthetic appearance of the device. Correspondingly, a second mounting groove can be formed in the housing 1 or the oil separating layer 6, and the second sealing ring 62 is limited through the second mounting groove.

Further, a third seal ring 63 is sandwiched between the oil-separating layer 6 and the base 2. A third mounting groove can be formed in the periphery of the base 2 or the inner wall of the oil separation layer 6, and the third sealing ring 63 is limited through the third mounting groove. In this embodiment, the first seal ring 61, the second seal ring 62, and the third seal ring 63 respectively seal the gap between the oil separation layer 6 and the suction port 14, the gap between the oil separation layer 6 and the housing 1, and the gap between the oil separation layer 6 and the base 2, so as to completely seal the oil storage chamber 4, prevent the oil liquid stored in the oil storage chamber 4 from flowing out of the gap, and prevent the aerosol generated by the atomizing core 3 from flowing into the gap.

In some embodiments of the utility model, the inner wall of the housing 1 is coated with a dense liquid-resistant coating to form the oil barrier layer 6. This not only eliminates the assembly process, but also does not create a gap between the oil barrier 6 and the housing 1.
