Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electronic atomization equipment, and particularly relates to a liquid guiding cotton, an atomization assembly and an electronic atomizer. BACKGROUND

[0002] The liquid guiding cotton in the prior art is a bidirectional liquid guiding structure, and the liquid guiding capacity is mainly realized by capillary force. The atomization liquid can penetrate from one side of the liquid guiding cotton to the opposite side. Conversely, reverse osmosis can also be realized, thereby forming a bidirectional liquid guiding effect. In the application of the electronic atomizer, the atomization liquid is guided by the liquid guiding cotton to the heating element for atomization. Once the atomization speed of the atomization liquid is greater than the liquid guiding speed, dry burning will occur, thereby causing a burnt wick. However, if the liquid supply is excessive, there will be a risk of liquid leakage.

[0003] At this time, the dry burning and burnt wick caused by insufficient liquid supply in a short time and the liquid leakage caused by excessive liquid supply coexist in the liquid guiding cotton used in the prior art, which is a technical problem difficult for technical personnel in the industry to solve. SUMMARY

[0004] The purpose of the embodiments of the application is to provide a liquid guiding cotton, an atomization assembly and an electronic atomizer, so as to solve the technical problem that the liquid guiding cotton structure used in the electronic atomizer in the prior art is prone to cause dry burning and burnt wick or liquid leakage.

[0005] To achieve the above purpose, the technical solution adopted by the application is:

[0006] In a first aspect, the embodiments of the application provide a liquid guiding cotton, which comprises a unidirectional liquid guiding structure and a non-unidirectional liquid guiding structure capable of bidirectional liquid guiding, and the unidirectional liquid guiding structure and the non-unidirectional liquid guiding structure together constitute at least one liquid guiding layer in the liquid guiding cotton.

[0007] The unidirectional liquid guiding structure comprises a plurality of microcavities arranged in a periodic oblique cut along the liquid guiding direction of the liquid guiding layer, the top of the microcavity has a first edge acute angle close to the upper wall of the liquid guiding layer, and the bottom of the microcavity has a second edge acute angle close to the lower wall of the liquid guiding layer.

[0008] In this way, the unidirectional liquid guiding structure and the non-unidirectional liquid guiding structure together constitute in the same liquid guiding layer.

[0018] In one embodiment, in the liquid guiding layer of the liquid guiding cotton, the one-way liquid guiding structure is arranged away from the electric heating element, so as to ensure the liquid guiding effect.

[0019] In one embodiment, in the plurality of liquid guiding layers of the liquid guiding cotton, the one-way liquid guiding structure on one liquid guiding layer is arranged away from the electric heating element, and the one-way liquid guiding structure on another liquid guiding layer is arranged close to the electric heating element.

[0043] In order to make the technical problems to be solved, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0046] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0047] The application provides a novel liquid guiding cotton, an atomization assembly and an electronic atomizer. The structure of the liquid guiding cotton is redesigned, so that the liquid guiding cotton has a high liquid storage function, can prevent dry burning and a burnt wick phenomenon caused by an atomization speed of atomized liquid being greater than a liquid guiding speed, and can also prevent liquid leakage caused by excessive liquid supply, thereby effectively prolonging the service life of the electronic atomizer.

[0048] The atomization assembly of the application is arranged in an electronic atomizer, and the atomization assembly has the liquid guiding cotton of the application. The liquid guiding cotton includes one or more liquid guiding layers. Please refer to Figure 1 and Figure 2 (the dark gray part in the figure is liquid, and the arrow is the flow trajectory of the liquid), and the liquid guiding cotton further includes a one-way liquid guiding structure 1 and a non-one-way liquid guiding structure 2.

[0049] The non-one-way liquid guiding structure 2 can adopt a traditional two-way liquid guiding structure on the liquid guiding cotton, as shown in Figure 2 . The liquid on the non-one-way liquid guiding structure 2 can be limited by the space of the liquid guiding layer, so as to realize forward or reverse flow.

[0050] The one-way liquid guiding structure 1 includes a plurality of microcavities 3, which are periodically and obliquely arranged along the liquid guiding direction of the liquid guiding layer. The “liquid guiding direction” herein can be understood as the flow direction of the liquid in the liquid guiding layer. For example, in the application of the electronic atomizer, the liquid guiding cotton can be arranged between a liquid storage chamber and a heating source, absorbs the atomized liquid in the liquid storage chamber, and guides the atomized liquid to the heating source for atomization, so the liquid guiding direction of the liquid guiding cotton is from the liquid storage chamber to the heating source.

[0051] Please refer to Figure 1 , Figure 2 and Figure 3 (I end in Figure 3 is schematically shown as the end away from the heating source, and II end is schematically shown as the other end close to the heating source). Each microcavity 3 in the one-way liquid guiding structure 1 has a first edge acute angle 31 close to the upper wall of the liquid guiding layer at the top, and each microcavity 3 has a second edge acute angle 32 close to the lower wall of the liquid guiding layer at the bottom. In actual application, the one end of the microcavity 3 where the first edge acute angle 31 is located is away from the heating source, and the other end of the microcavity 3 where the second edge acute angle 32 is located is close to the heating source.

[0052] Under the above obliquely arranged microcavity structure, as shown in Figure 3 , the liquid is fixed, so as to prevent the liquid outside the microcavity 3 from flowing into the microcavity 3, and the liquid inside the microcavity 3 flows from the upper edge of one microcavity 3 to the upper edge of the next microcavity 3 under the surface gradient of the microcavity 3, so as to strengthen the capillary effect of the upper edge of the microcavity 3, thereby realizing directional transportation of the liquid. At the same time, due to the existence of the microcavity 3, the microcavity structure can also play a role in storing liquid.

[0053] The aforementioned unidirectional liquid-guiding structure 1 and non-unidirectional liquid-guiding structure 2 together constitute at least one liquid-guiding layer in the liquid-guiding cotton. This can be understood as, for example... Figure 1 , Figure 2 and Figure 3 As shown, within the same liquid-conducting layer, the portion with microcavities 3 is a unidirectional liquid-conducting structure 1, while the remaining portions of the liquid-conducting layer without microcavities 3 can be non-unidirectional liquid-conducting structures 2. Thus, within the same liquid-conducting layer, the unidirectional liquid-conducting structure 1 functions to direct and store the liquid, while the portions of the liquid-conducting layer other than the unidirectional liquid-conducting structure 1 are all non-unidirectional liquid-conducting structures 2, enabling bidirectional liquid guidance and allowing liquid reflux.

[0054] Compared with the prior art, the liquid-guiding cotton provided in this application embodiment combines a unidirectional liquid-guiding structure 1 and a non-unidirectional liquid-guiding structure 2 in the same liquid-guiding layer.

[0055] Among them, such as Figure 3 As shown, the unidirectional liquid guiding structure 1 has obliquely arranged microcavities 3, which can fix the liquid and prevent liquid outside the microcavities 3 from flowing into the interior of the microcavities 3. Meanwhile, the liquid inside the microcavities 3, under the action of the surface gradient of the microcavities 3, enhances the capillary effect at the upper edge of the microcavities 3, thus allowing the liquid to continuously enter from the upper edge of one microcavity 3 to the next, achieving directional transport of the liquid. At the same time, the presence of the microcavities 3 increases the liquid storage capacity of the liquid guiding cotton, ensuring sufficient liquid supply and greatly alleviating the dry burning and scorching phenomenon caused by insufficient liquid supply in a short time in electronic atomizers.

[0056] Non-unidirectional liquid-guiding structure 2 in the same liquid-guiding layer can guide liquid in both directions, such as Figure 3 As shown, when the liquid supply is too high, this part of the structure will cause the liquid to flow back, thereby preventing leakage caused by the directional liquid guiding function of the unidirectional liquid guiding structure 1.

[0057] As can be seen, within the same liquid-guiding layer of the liquid-guiding cotton in this application, one part is provided with a unidirectional liquid-guiding structure 1, and the other part is provided with a non-unidirectional liquid-guiding structure 2. The two structures are cleverly combined so that the liquid-guiding cotton has both the directional liquid guiding and liquid storage performance of the unidirectional liquid-guiding structure 1, which can alleviate the dry burning and scorching phenomenon caused by insufficient liquid supply in the electronic atomizer in a short time, and the bidirectional liquid guiding performance of the non-unidirectional liquid-guiding structure 2, which allows the liquid to flow back, thereby avoiding the problem of leakage in the electronic atomizer due to excessive liquid supply. This effectively improves the overall performance of the liquid-guiding cotton and helps to extend the service life of the electronic atomizer.

[0058] For the microcavity structure in the one-way liquid guiding structure 1, the microcavity 3 can be any one of symmetric or asymmetric wedge shape, parallelogram, ellipse, spindle shape, or any two or more combinations. In an embodiment of the present application, please refer to Figure 1 , Figure 2 and Figure 3 In the same liquid guiding layer of the liquid guiding cotton, a part is the one-way liquid guiding structure 1 and another part is the non-one-way liquid guiding structure 2. The one-way liquid guiding structure 1 is constructed by a plurality of wedge-shaped microcavities 3 arranged asymmetrically and obliquely, and the wedge-shaped microcavities 3 are arranged periodically along the liquid guiding direction of the liquid guiding layer.

[0059] The top of each wedge-shaped microcavity 3 has a first edge acute angle 31, and the bottom of each wedge-shaped microcavity 3 has a second edge acute angle 32. In actual application, the liquid guiding cotton is arranged so that the one end of the wedge-shaped microcavity 3 with the first edge acute angle 31 is away from the heat source, and the other end of the wedge-shaped microcavity 3 with the second edge acute angle 32 is close to the heat source, thereby setting the liquid guiding direction of the one-way liquid guiding structure 1.

[0060] Preferably, the angle α of the first edge acute angle 31 and the angle β of the second edge acute angle 32 are set to 2°-8°, so that the microcavity structure in the liquid guiding cotton is more in line with the principle of Gibbs inequality. At this angle, the liquid is better fixed, preventing the liquid outside the microcavity 3 from flowing into the microcavity 3. The liquid inside the microcavity 3 is under the action of the surface gradient of the microcavity 3, so that the capillary effect of the upper edge of the microcavity 3 is enhanced, thereby making the liquid continuously enter the next microcavity 3 from the upper edge of the microcavity 3, realizing the directional transport of the liquid, and increasing the utilization rate of the atomized liquid.

[0061] For the material of the liquid guiding cotton, the material of the liquid guiding layer in the liquid guiding cotton of the present application can be preferably any one of cotton fiber, hemp fiber, viscose fiber, or any two or more combinations, which is not limited here.

[0062] Since the liquid guiding cotton provided by the embodiment of the present application has a part of the one-way liquid guiding structure 1 and another part of the non-one-way liquid guiding structure 2 in the same liquid guiding layer, the densities of the two structures can be set. The density of the one-way liquid guiding structure 1 is preferably set to 30-50 g / m 2 , so that the microcavities 3 are arranged uniformly. The density of the non-one-way liquid guiding structure 2 is preferably set to 50-75 g / m 2 , so that the layout of the whole liquid guiding layer is saturated, thereby improving the liquid guiding and liquid storage effect of the liquid guiding cotton.

[0063] For the whole structure of the liquid guiding cotton provided in the embodiments of the present application, in another embodiment of the present application, the liquid guiding cotton comprises a plurality of liquid guiding layers, the plurality of liquid guiding layers comprise single structure layers and composite layers, the single structure layers have the non-unidirectional liquid guiding structure 2, and the composite layers have the non-unidirectional liquid guiding structure 2 and the unidirectional liquid guiding structure 1.

[0064] In this way, in the plurality of liquid guiding layers of the liquid guiding cotton, the single structure layers play the role of bidirectional liquid guiding, and the composite layers play the role of liquid storage and directional liquid guiding, thereby effectively improving the overall performance of the liquid guiding cotton.

[0065] For the shape of the microcavity 3 in each composite layer, it can be the same or different. For example, the microcavity 3 in one composite layer is an asymmetric wedge-shaped microcavity 3, and the microcavity 3 in another composite layer is any one of a symmetric parallelogram, an ellipse, and a spindle. In this way, each composite layer with different or the same microcavity shape can be flexibly matched and combined to obtain better liquid guiding effect.

[0066] In actual application, the microcavity 3 on the unidirectional liquid guiding structure 1 needs to be processed and formed by a cavity opening tool, so that the unidirectional liquid guiding structure 1 after processing and forming will form an opening corresponding to each microcavity 3 on the surface of the liquid guiding layer, which will affect the liquid guiding and storage.

[0067] Therefore, in one embodiment of the present application, the plurality of single structure layers and the plurality of composite layers are arranged in a staggered manner along the height direction of the liquid guiding cotton. Specifically, it is preferred that the outermost liquid guiding layers all adopt single structure layers, that is, the topmost layer and the bottommost layer of the plurality of liquid guiding layers of the liquid guiding cotton all adopt single structure layers. In this way, the single structure layers are used to cover the surfaces of the composite layers to cover the openings existing on the surface of the microcavity 3 on the composite layers, thereby effectively ensuring the directional liquid guiding performance and the liquid storage performance of the unidirectional liquid guiding structure 1.

[0068] As an example, please refer to Figure 4 The liquid guiding cotton has 5 liquid guiding layers, which include a first liquid guiding layer 101, a second liquid guiding layer 102, a third liquid guiding layer 103, a fourth liquid guiding layer 104, and a fifth liquid guiding layer 105 from top to bottom. Among them, the first liquid guiding layer 101, the third liquid guiding layer 103, and the fifth liquid guiding layer 105 are single structure layers, and the second liquid guiding layer 102 and the fourth liquid guiding layer 104 are composite layers. In this way, the first liquid guiding layer 101, the third liquid guiding layer 103, and the fifth liquid guiding layer 105 of the single structure are covered on the upper and lower surfaces of the second liquid guiding layer 102 and the fourth liquid guiding layer 104 of the composite structure, thereby effectively ensuring the overall liquid guiding performance and liquid storage performance of the liquid guiding cotton.

[0069] For the number of liquid guiding layers in the above-mentioned liquid guiding cotton, it can also be 3 to 10 layers, as long as the upper and lower surfaces of the composite layers in the liquid guiding layers can be covered by the single structure layers, which are not limited here.

[0070] For the setting position of the one-way liquid guide structure 1 in each composite layer, in an embodiment of the present application, the one-way liquid guide structure 1 in each composite layer is arranged close to one side of the composite layer. As an example, please refer to Figure 5 , the one-way liquid guide structure 1 in the second liquid guide layer 102 and the fourth liquid guide layer 104 of the composite layer is arranged away from the heat source.

[0071] In another embodiment of the present application, in two adjacent composite layers, the one-way liquid guide structure 1 in the two composite layers is arranged staggered with each other. As an example, please refer to Figure 6 and Figure 7 , on the second liquid guide layer 102 and the fourth liquid guide layer 104 of the composite layer, the one-way liquid guide structure 1 in the second liquid guide layer 102 is arranged away from the heat source, and the one-way liquid guide structure 1 in the fourth liquid guide layer 104 is arranged close to the heat source. By staggered arrangement of the one-way liquid guide structure 1 in the adjacent composite layers, the overall liquid storage and liquid guide balance of the liquid guide cotton is improved, effectively avoiding liquid leakage caused by the liquid supply being greater than the consumption, and avoiding the wick caused by the liquid supply being less than the consumption, thereby improving the overall performance of the liquid guide cotton.

[0072] In addition, the setting position of the one-way liquid guide structure 1 in the composite layer can be further optimized to further improve the liquid storage and liquid guide balance of the composite layer.

[0073] It should be noted that the above composite layer is mainly composed of the one-way liquid guide structure 1 and the non-one-way liquid guide structure 2, which means that in the same liquid guide layer, the part of the liquid guide layer other than the one-way liquid guide structure 1 can be the non-one-way liquid guide structure 2. At this point, the one-way liquid guide structure 1 in the composite layer functions to guide the liquid in one direction, and the part of the composite layer other than the one-way liquid guide structure 1 is the non-one-way liquid guide structure 2 and can achieve the performance of guiding the liquid in both directions, allowing the liquid to flow back.

[0074] In this way, the setting position of the one-way liquid guide structure 1 in the thickness direction of the composite layer can be further adjusted, so that the upper and lower parts of the one-way liquid guide structure 1 form the liquid passage of the non-one-way liquid guide structure 2, and the gap between the top and / or bottom of the one-way liquid guide structure 1 and the upper and lower walls of the liquid guide layer realizes the bidirectional flow, so that the atomized liquid can flow back, to further alleviate the problem of liquid leakage caused by the liquid supply being less than the consumption of the atomized liquid.

[0075] Specifically, in an embodiment of the present application, please refer to Figure 8 , the one-way liquid guide structure 1 is arranged close to the upper surface wall of the liquid guide layer in the thickness direction of the liquid guide layer, so that the bottom of each microcavity 3 in the one-way liquid guide structure 1 is separated from the lower surface wall of the liquid guide layer to form a liquid passage 4.

[0076] In another embodiment of the present application (not shown), the one-way liquid guiding structure 1 is arranged near the lower surface wall of the liquid guiding layer in the thickness direction of the liquid guiding layer, so that the top of each microcavity 3 in the one-way liquid guiding structure 1 is spaced apart from the upper surface wall of the liquid guiding layer to form the liquid passing channel 4.

[0077] In a third embodiment of the present application, please refer to Figure 9 and Figure 10 , the one-way liquid guiding structure 1 is arranged in the liquid guiding layer in the thickness direction of the liquid guiding layer, and the top and bottom of each microcavity 3 in the one-way liquid guiding structure 1 are arranged to be spaced apart from the upper surface wall and the lower surface wall of the liquid guiding layer, respectively, and form two liquid passing channels 4.

[0078] Figure 9 L1, L2, L3 and L4 in the above formula represent the thickness of the upper and lower bidirectional liquid passing channels 4 in each composite layer, and the values of L1, L2, L3 and L4 can be preferably set as L1mm < L1 < 7mm, 1mm < L2 < 7mm, 1mm < L3 < 7mm, and 1mm < L4 < 7mm. The values of L1, L2, L3 and L4 can be the same or different, and can be matched according to actual application, which is not specifically limited here.

[0079] In another embodiment of the present application, please refer to Figure 11 and Figure 12 , the present application also provides an atomization assembly, which comprises the liquid guiding cotton 100 and the electric heating element 200 of the present application, and the electric heating element 200 can be wound into a cylindrical structure.

[0080] The liquid guiding cotton 100 surrounds the outer periphery of the electric heating element 200, so that the center of the electric heating element 200 forms an atomization channel 300. The outer periphery of the electric heating element 200 and the liquid guiding cotton 100 can be arranged close to each other or in contact with each other.

[0081] Please refer to Figure 3 and Figure 12 , in the liquid guiding layer with the one-way liquid guiding structure 1, each microcavity 3 in the one-way liquid guiding structure 1 is arranged obliquely, one end of the first edge acute angle 31 on each microcavity 3 is arranged away from the electric heating element 200, and the other end of the second edge acute angle 32 on the microcavity 3 is arranged close to the electric heating element 200, so as to limit the flow direction of the liquid.

[0082] In the liquid guiding layer composed of the unidirectional liquid guiding structure 1 and the non-unidirectional liquid guiding structure 2, the unidirectional liquid guiding structure 1 uses obliquely arranged microcavities 3 to guide the liquid in a directional manner, increasing the utilization rate of the atomizing liquid and simultaneously having a liquid storage function, ensuring sufficient liquid supply and greatly alleviating the dry burning and scorching phenomenon caused by insufficient liquid supply in a short period of time during the operation of the atomizing component. The non-unidirectional liquid guiding structure 2 exists in the liquid guiding layer outside of the unidirectional liquid guiding structure 1. Utilizing the bidirectional liquid guiding performance of the non-unidirectional liquid guiding structure 2, when the liquid supply is excessive, this part of the structure can cause the liquid to flow back, thereby preventing the leakage problem in the atomizing channel 300 caused by excessive liquid supply due to the directional liquid guiding of the unidirectional liquid guiding structure 1.

[0083] Regarding the configuration of the liquid-guiding cotton 100 in the atomizing component, please refer to one embodiment of this application. Figure 5 and Figure 12 In the liquid guiding layer with unidirectional liquid guiding structure 1, the unidirectional liquid guiding structure 1 is set away from the heating element 200 to ensure the liquid guiding effect.

[0084] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 6 and Figure 12 In the liquid guiding layer with unidirectional liquid guiding structure 1, the unidirectional liquid guiding structure 1 on one liquid guiding layer is disposed away from the heating element 200, and the unidirectional liquid guiding structure 1 on the other liquid guiding layer is disposed close to the heating element 200.

[0085] As an example, such as Figure 6 and Figure 7 As shown ( Figure 7 The II end is the end where the heating element 200 is located. The second liquid guiding layer 102 and the fourth liquid guiding layer 104 are both composite layers with a unidirectional liquid guiding structure 1 and a non-unidirectional liquid guiding structure 2. The unidirectional liquid guiding structure 1 in the second liquid guiding layer 102 is disposed on the side away from the heating element 200, and the unidirectional liquid guiding structure 1 in the fourth liquid guiding layer 104 is disposed on the side close to the heating element 200.

[0086] In this way, by utilizing the staggered arrangement of the unidirectional liquid guiding structure 1 in the composite layer, the overall liquid storage and liquid guiding balance of the liquid guiding cotton is improved, effectively avoiding leakage of the atomization channel 300 due to the liquid supply being greater than the consumption, and avoiding the clogging phenomenon of the atomization component due to the liquid supply being less than the consumption, thereby improving the overall performance of the atomization component.

[0087] In another embodiment of this application (not shown in the figures), this application also provides an electronic atomizer, including a housing, a liquid reservoir, and the atomizing component described above. The housing can be configured according to aesthetic requirements, and is not specifically limited here.

[0088] The liquid storage container and the atomization assembly are both accommodated inside the shell, and can be combined together according to the internal layout of the shell.

[0089] The liquid guiding cotton 100 can be wholly or at least partially arranged in the liquid storage container, and can absorb the atomized liquid stored in the liquid storage container. The liquid guiding layer with the one-way liquid guiding structure 1 and the non-one-way liquid guiding structure 2 in the liquid guiding cotton 100 can prevent the dry burning and the wick burning phenomenon caused by the atomization speed of the atomized liquid being greater than the liquid guiding speed, and can also prevent the liquid leakage caused by excessive liquid supply, thereby effectively prolonging the service life of the electronic atomizer.

[0090] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
