[0051] Reference Figures 1-4 Some embodiments of the present application provide an oil storage cotton 100 for storing and guiding the atomized liquid of an electronic cigarette, the oil storage cotton 100 comprising a main body. The main body comprises a first through hole 110, a first oil storage layer 120 surrounding the outer periphery of the first through hole 110, and a second oil storage layer 130 surrounding the outer periphery of the first oil storage layer 120, the first through hole 110 being configured to accommodate an atomizing core 200 of the electronic cigarette; wherein, in the radial direction of the first through hole 110, the permeability of the second oil storage layer 130 is greater than that of the first oil storage layer 120.

[0052] The advantage is that, in the oil storage cotton 100 of the above-mentioned embodiments, the first oil storage layer 120 is close to the first through hole 110, and the second oil storage layer 130 is away from the first through hole 110, and the first oil storage layer 120 has lower permeability than the second oil storage layer 130; by virtue of the difference in permeability between the second oil storage layer 130 and the first oil storage layer 120, the design is conducive to gradient limiting of the atomized liquid flowing too fast during oil guiding, and reduces the phenomenon of atomized liquid flowing too fast causing atomization oil leakage; this design enables the design of the oil storage cotton 100 to adjust the permeability of the first oil storage layer 120 and the permeability of the second oil storage layer 130 according to demand, so that the oil storage cotton 100 maintains a relatively high oil storage capacity and permeability in the second oil storage layer 130, and maintains a reasonable permeability in the first oil storage layer 120, so as to overall gradient balance and adjust the liquid storage capacity, leakage prevention capacity and oil guiding capacity of the oil storage cotton 100; at the same time, the first oil storage layer 120 has lower permeability than the second oil storage layer 130, which can also effectively prevent the phenomenon of inconsistent taste of each puff of aerosol caused by too fast loss of small molecule substances in the atomized liquid; it can achieve a balance of oil storage, oil guiding and sealing to reduce oil leakage, and can provide a certain oil guiding capacity while having good sealing performance to reduce oil leakage.

[0053] Explanatorily, the permeability refers to the ability of liquid to pass through a porous medium, which can be tested or calculated by using existing formulas, and specific details are not described herein.

[0054] In addition, for the implementation that, in the radial direction of the first through hole 110, the permeability of the second oil storage layer 130 is greater than that of the first oil storage layer 120. Reference Figures 1-4In some embodiments, the first oil storage layer 120 has a density greater than that of the second oil storage layer 130. The oil storage cotton 100 has at least two regions with different densities, i.e., the flowability of the atomized liquid in the at least two regions with different densities is different. Generally, the oil storage cotton 100 itself has a fluffy structure with a large number of voids, and the higher the density, the greater the flowability of the atomized liquid. By virtue of the difference in density, the flow of the atomized liquid is limited, and the atomized liquid is prevented from flowing too fast and causing atomization leakage. At the same time, the phenomenon of inconsistent taste of each aerosol due to the too fast flow of small molecules in the atomized liquid can also be effectively prevented.

[0055] In some embodiments, referring to Figures 1-4 , the first oil storage layer 120 has a porosity less than that of the second oil storage layer 130. Generally, the greater the porosity, the greater the permeability. Therefore, by making the porosity of the first oil storage layer 120 less than that of the second oil storage layer 130, a gradient permeability design can be achieved. The principle of changing the permeability is essentially the same as that of the density gradient difference, and will not be described in detail.

[0056] More specifically, in some embodiments, the oil storage cotton 100 can be a cotton body structure formed by disordered connection between needle filaments, and the gaps generated in the oil storage cotton 100 are used to store the atomized liquid. The greater the density, the smaller the gap, and the smaller the amount of atomized liquid in the unit gap. Therefore, in these unit gaps, the atomized liquid in the unit gap is mutually restrained by the liquid surface tension, thereby achieving the effect of effectively hindering the flowability.

[0057] In some embodiments, referring to Figures 1-4 , the first oil storage layer 120 and the second oil storage layer 130 are integrally formed. Integrally forming can reduce the number of parts, simplify the processing and assembly process, and reduce production costs.

[0058] In some other embodiments, the first oil storage layer 120 and the second oil storage layer 130 are in a split structure. The split structure can be replaced individually, and has higher flexibility.

[0059] In some embodiments, referring to Figures 1-4, the main body is a column with a first through hole 110, and in the radial direction of the first through hole 110, the thickness of the first oil storage layer 120 is less than the thickness of the second oil storage layer 130. The thickness of the second oil storage layer 130 is thicker, which can store more atomized liquid through the adsorption of the second oil storage layer 130, and can supply sufficient atomized liquid for atomization in time, reducing the phenomenon of dry burning. If the thickness of the first oil storage layer 120 is too large, it may cause insufficient oil guiding and burning phenomenon. The thickness of the first oil storage layer 120 can be represented by L1, and the thickness of the second oil storage layer 130 can be represented by L2. When L1

[0060] Further, in some embodiments, the density of the first oil storage layer 120 is 0.18-0.4g / cm 3 , and the density of the second oil storage layer 130 is 0.06-0.19g / cm 3 . Through a large number of experiments, for the current electronic cigarette, using the above density parameters is beneficial to balance the performance of the oil guiding cotton in oil storage, oil guiding and oil leakage prevention as a whole.

[0061] In some embodiments, referring to Figures 3-4 , the main body further includes a third oil storage layer 140, which is surrounded between the first through hole 110 and the first oil storage layer 120; wherein in the radial direction of the first through hole 110, the permeability of the third oil storage layer 140 is greater than that of the first oil storage layer 120.

[0062] For the oil storage cotton 100 containing the third oil storage layer 140, in some embodiments, the density of the first oil storage layer 120 is 0.18-0.4g / cm 3 , the density of the second oil storage layer 130 is 0.06-0.19g / cm 3 , and the density of the third oil storage layer 140 is 0.1-0.2g / cm 3 .

[0063] In some embodiments, the first oil storage layer 120, the second oil storage layer 130, and the third oil storage layer 140 are formed by randomly connecting the needle filaments to form a cotton structure having gaps for storing oil. The oil storage cotton 100 is formed by randomly connecting the needle filaments to form a cotton structure, and the gaps generated in the oil storage cotton 100 are used to store the atomized liquid. When the density is greater, the gaps are smaller, and the amount of atomized liquid in the unit gaps is smaller. Therefore, in these unit gaps, the atomized liquid in the unit gaps is restrained from flowing by the liquid surface tension, thereby achieving the effect of effectively hindering the fluidity. In some embodiments, the cotton structure can be a defatted cotton, an organic cotton, a polyester fiber cotton, a linen cotton, or an oil-impregnated cotton. The first oil storage layer 120, the second oil storage layer 130, and the third oil storage layer 140 can be made of the same material.

[0064] For the oil storage cotton 100 of any of the above embodiments, with reference to Figure 5 Some embodiments of the present application also provide an atomization cartridge, which includes a cartridge shell 300, an atomization core 200, and the oil storage cotton 100 of any of the above embodiments. The cartridge shell 300 is provided with a first mounting hole 310, and the side wall of the first mounting hole 310 is provided with an oil inlet hole 320 in communication with the first mounting hole 310. The oil storage cotton 100 is arranged in the first mounting hole 310, and the atomization core 200 is arranged in the first through hole 110 of the oil storage cotton 100. Since the oil storage cotton 100 adopts the improved structure provided in the above embodiments, it can achieve a balance between oil storage, oil guiding, and sealing to reduce oil leakage. It can provide a certain oil guiding capacity while having good sealing performance to reduce oil leakage. Details are not described again. The atomization cartridge is a consumable of an electronic cigarette and can be independently assembled and disassembled as a single independent accessory. The atomization core 200 can adopt an existing structure, and details are not described again.

[0065] For the oil storage cotton 100 of any of the above embodiments, with reference to Figures 6-7 Some embodiments of the present application also provide an atomizer, which includes an oil storage chamber body 400 and the oil storage cotton 100. The oil storage chamber body 400 is provided with a liquid storage cavity 410 and a second mounting hole 420 arranged separately from the liquid storage cavity 410. The hole wall of the second mounting hole 420 is provided with an oil outlet hole 430, and the oil outlet hole 430 communicates the liquid storage cavity 410 and the second mounting hole 420. The oil storage cotton 100 is inserted into the second mounting hole 420 and communicates with the oil outlet hole 430.

[0066] Since the permeability of the second oil storage layer 130 is greater than that of the first oil storage layer 120, when a large amount of atomized liquid is close to the atomizing core 200 in the first through hole 110, the flowability of the atomized liquid can be slowed down, and the atomized liquid can be prevented from leaking out of the atomizing core 200; the second oil storage layer 130 is close to the oil storage chamber body 400, so that more atomized liquid can be adsorbed, and sufficient atomized liquid can be ensured to be supplied to the area of the first oil storage layer 120. The second oil storage layer 130 has relatively high permeability, and can guide the atomized liquid in the oil storage chamber to the oil storage cotton 100 through the capillary phenomenon or the adsorption force of the second oil storage layer 130 itself, and reduce the obstruction to the macromolecular flavoring substances, so as to further ensure that the aerosol generated after the atomized liquid is atomized has better taste consistency.

[0067] Further, with reference to Figures 6-7 In some embodiments, the atomizer further comprises a shell 300 and the atomizing core 200. The shell 300 is provided with a first mounting hole 310, a side wall of the first mounting hole 310 is provided with an oil inlet hole 320 in communication with the first mounting hole 310, the oil storage cotton 100 is arranged in the first mounting hole 310 and covers the oil inlet hole 320, and the shell 300 is inserted into the second mounting hole 420; the atomizing core 200 is arranged in the first through hole 110 of the oil storage cotton 100, and the oil storage cotton 100 is in communication with the liquid storage cavity 410 through the oil inlet hole 320 and the oil outlet hole 430. The shell 300, the atomizing core 200 and the oil storage cotton 100 can constitute the atomizing cartridge in the above-mentioned embodiments, and the atomizing cartridge can be individually installed, removed and replaced.

[0068] For the oil storage cotton 100 in any of the above-mentioned embodiments, some embodiments of the present application further provide an electronic cigarette, which comprises the atomizer in any of the above-mentioned embodiments, and details are not described herein.

[0069] Finally, it should be noted that any combination of the technical features of the above-mentioned embodiments can be made, and in order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, however, as long as the combination of the technical features does not exist, it should be considered that it is within the scope of the present application.

[0070] The above-mentioned embodiments only express one of the embodiments of the present application, the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, on the premise of not departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
