In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

It should be noted that, the terms "upper", "lower", "left", "right", and the like in the embodiments of the present application are described in terms of the angles shown in the drawings, and should not be construed as limiting the embodiments of the present application. In the context of this document, it will also be understood that when an element is referred to as being "on" or "under" another element, it can be directly on the other element or be indirectly on the other element through intervening elements.

In the prior art, the original liquid is formed by stacking three layers of spunlaced non-woven fabrics, the spunlaced non-woven fabrics are usually made of American cotton, the thickness of each layer of the spunlaced non-woven fabrics is 0.5mm, the total thickness of the original liquid is 1.5mm, and the gram weight tolerance delta M can be achieved: -13% or more and delta M or less and +13% or less. Adjacent non-woven fabrics layer is through the mode fixed connection of pressfitting edge, and the problem of separation that drops between layer and the layer easily appears in processing, transportation and equipment in-process leads to the loss big, and does not adapt to the production demand of automatic equipment, leads to the suitability and the yield of liquid relatively poor. On the other hand, the multilayer stack results in poor consistency of grammage of the liquid guide, i.e. a large grammage tolerance range, and the risk of uneven liquid guide easily occurs.

In order to solve the above-mentioned problem, this application embodiment provides a liquid guiding body 1, and this liquid guiding body 1 is the integrated structure that a plurality of short fibers interweave and form each other, has reduced liquid guiding body 1 in installation, transportation, the risk that drops between layer and the layer to the production yield and the job stabilization nature of liquid guiding body 1 have been promoted, and liquid guiding body 1's life has been prolonged. And as shown in fig. 6, the liquid guiding body 1 at least comprises a first layer 11 and a second layer 12 which are arranged along the thickness direction of the liquid guiding body, that is to say, the first layer 11 and the second layer 12 of the liquid guiding body are mutually interwoven through short fibers to form an integrated structure, so that the liquid guiding body 1 has good stability, and meanwhile, the problem that layers are not easy to fall off is solved, the processing difficulty of the liquid guiding body 1 is reduced, the processing cost of the liquid guiding body 1 is reduced, and the processing period of the liquid guiding body 1 is shortened.

In addition, the number of layers of the first layer 11 may be one or more, and the number of layers of the second layer 12 may be one or more, so as to increase the flexibility of the structure of the liquid guide 1, thereby facilitating the processing of the liquid guide 1.

The short fibers comprise first short fibers 111 and second short fibers 121, the first layer 11 is formed by interweaving the first short fibers 111, and the second layer 12 is formed by interweaving a plurality of second short fibers 121. When the material of the first short fibers 111 is the same as that of the second short fibers 121, the length of the first short fibers 111 is different from that of the second short fibers 121; when the material of the first staple fiber 111 is different from the material of the second staple fiber 121, the length of the first staple fiber 111 may be the same as or different from the length of the second staple fiber 121, so as to increase the flexibility of parameters such as the material and length of the staple fiber, thereby increasing the flexibility of the structure of the liquid guiding body 1.

The materials of the first short fibers 111 and the second short fibers 121 include, but are not limited to, natural cellulose fibers, regenerated cellulose fibers, aramid fibers, and polyimide, and the materials of the first short fibers 111 and the second short fibers 121 may be the same or different; natural cellulosic fibers include, but are not limited to, cotton fibers, kapok fibers, hemp fibers, bamboo fibers, lotus fibers, tea fibers, and the like; regenerated cellulose fibers include, but are not limited to, viscose, rayon, modal, tencel, lyocell, lanin, asahi, cuprammonium, and the like. In the production process, the material of the short fiber can be adaptively adjusted according to the use environment of the liquid guide body 1, the liquid guide speed and other requirements, so as to increase the liquid guide effect of the liquid guide body 1 and the application range of the liquid guide body 1.

When the first layer 11 is used for installing the heating component 2 and the second layer 12 is used for contacting with atomized liquid, the length of the first short fiber 111 is smaller than that of the second short fiber 121, so that the liquid guiding speed of the second layer 12 is increased, the risk of the first layer 11 being stuck with a core is reduced, meanwhile, the liquid guiding speed of the first layer 11 is reduced, and the risk that the liquid guiding speed of the first layer 11 is larger than that of the heating component to cause liquid leakage of the first layer 11 is reduced.

When the first layer 11 is used for installing the heating component 2 and the second layer 12 is used for contacting with atomized liquid, the first short fibers 111 are made of high-temperature resistant natural cellulose fibers so as to reduce the risk of pasting the core of the first layer 11, and the second short fibers 121 are made of regenerated cellulose fibers with high liquid absorption rate so as to improve the liquid guiding speed of the second layer 12. Wherein the thickness of the first layer 11 is greater than 0.2mm, thereby further reducing the risk of the first layer 11 sticking cores; in addition, the thickness of the second layer 12 is greater than 0.2mm, reducing the risk of the first layer 11 being thick and not easy to process.

More specifically, as shown in fig. 7, according to the length and the material quality of the short fiber, the short fiber further includes a third short fiber 131, the third short fiber 131 is interwoven into a third layer 13, and the third layer 13 is disposed between the first layer 11 and the second layer 12 along the thickness direction of the liquid guiding body 1, so as to reduce the thickness of the first layer 11 and the second layer 12, thereby reducing the processing difficulty of the liquid guiding body 1. The third short fibers and the first short fibers at the junction of the third layer body and the first layer body are interwoven, and the third short fibers and the second short fibers at the junction of the third layer body and the second layer body are interwoven.

The third staple fibers 131 may be made of, but not limited to, natural cellulose fibers, regenerated cellulose fibers, aramid fibers, and polyimide, and the third staple fibers 131 may be made of the same material as the first staple fibers 111 or different materials from the second staple fibers 121. Specifically, the third staple fibers 131 are regenerated cellulose fibers with high liquid absorption rate, so as to improve the liquid guiding speed of the third staple fibers 131.

In addition, the liquid guiding body 1 may further include a fourth layer body (not labeled in the drawing) formed by interweaving fourth short fibers (not labeled in the drawing), a fifth layer body (not labeled in the drawing) formed by interweaving fifth short fibers (not labeled in the drawing), and the like, and the different layer bodies are all formed into an integral structure by interweaving the short fibers, so that the types of the short fibers and the layer number of the liquid guiding body 1 are not particularly limited.

In this embodiment, the length L of the staple fiber satisfies: l is more than or equal to 0.1mm and less than or equal to 10mm, and can be more specifically 1mm,5mm,9mm and the like.

If the length L of the short fiber is smaller (namely L is smaller than 0.1 mm), the processing difficulty of the short fiber is increased, so that the production period of the liquid guide body 1 is increased; if the length L of the short fibers is larger (namely L is more than 10 mm), the processing difficulty is increased, meanwhile, the risk of uneven gaps between adjacent short fibers is increased, and the liquid guiding uniformity of the liquid guiding body 1 is reduced.

Therefore, L is more than or equal to 0.1mm and less than or equal to 10mm, and the liquid guiding uniformity of the liquid guiding body 1 can be improved while the liquid guiding speed of the liquid guiding body 1 is improved.

Specifically, as shown in fig. 2, the thickness H of the liquid guide 1 satisfies: h is more than or equal to 1mm and less than or equal to 4mm.

In this embodiment, if the thickness of the liquid guiding body 1 is smaller (i.e. H < 1 mm), in order to reduce the risk of leakage of the liquid guiding body 1, the size of the liquid guiding body 1 immersed in the atomized liquid needs to be reduced, thereby reducing the liquid guiding rate of the liquid guiding body 1; if the thickness of the liquid guide 1 is large (i.e., H > 4 mm), the liquid guide speed of the liquid guide 1 is slow. Therefore, H is more than or equal to 1mm and less than or equal to 4mm, the liquid guiding speed of the liquid guiding body 1 can be improved while the risk of liquid leakage of the atomization assembly is reduced, and the working efficiency of the liquid guiding body 1 is improved.

Specifically, the grammage M of the leader liquid 1 satisfies: 100g/m ² ≤M≤600g/m ² Specifically, it may be 200g/m ² ，350g/m ² ，560g/m ² Etc.

If the grammage of the liquid guide 1 is small (i.e. M < 100g/M ² ) The number of the short fibers in unit volume is smaller, the gaps between the adjacent short fibers are larger, the liquid guiding speed of the liquid guiding body 1 is higher, and the liquid leakage phenomenon is easy to occur; if the grammage of the liquid guide 1 is large (i.e. M > 600g/M ² ) The number of short fibers in a unit volume is large, and the gaps between adjacent short fibers are small, so that the liquid guiding speed of the liquid guiding body 1 is low. Thus, 100g/m ² ≤M≤600g/m ² The risk of leakage of the liquid guiding body 1 can be reduced, and the liquid guiding speed of the liquid guiding body 1 can be improved.

Alternatively, the grammage M of the leader liquid 1 satisfies: 150g/m ² ≤M≤350g/m ² Thereby further reducing the risk of leakage of the liquid guiding body 1 and further improving the liquid guiding speed of the liquid guiding body 1.

Further, the liquid absorption ratio W of the liquid guide 1 satisfies: w is more than or equal to 20% and less than or equal to 2500%, and can be specifically 500%,1000%,2000% and the like.

In this embodiment, if the liquid absorption rate of the liquid guiding body 1 is smaller (i.e. W < 20%), the liquid guiding speed of the liquid guiding body 1 is slower, so that the liquid guiding speed of the liquid guiding body 1 is smaller than the atomization speed of the heating component 2 mounted on the liquid guiding body 1, and the risk of burning the liquid guiding body 1 by the heating component 2 easily occurs; if the liquid absorption rate of the liquid guiding body 1 is larger (i.e. W > 2500%), the liquid guiding speed of the liquid guiding body 1 is higher, so that the liquid guiding speed of the liquid guiding body 1 is larger than the atomization speed of the heating component 2, and the risk of liquid leakage is easy to occur. Therefore, W is more than or equal to 20% and less than or equal to 2500%, so that the liquid guiding speed of the liquid guiding body 1 and the atomizing speed of the heating component 2 are kept balanced, the risk of burning the liquid guiding body 1 by the heating component 2 is reduced, the service life of the liquid guiding body 1 is prolonged, and the risk of liquid leakage of the liquid guiding body 1 is reduced.

Alternatively, the liquid absorption W of the liquid guide 1 satisfies: w is more than or equal to 200% and less than or equal to 1000%, the service life of the liquid guiding body 1 is further prolonged, and the risk of liquid leakage of the liquid guiding body 1 is further reduced.

As shown in fig. 9, the surface of the optional short fiber is provided with fluff to increase the contact area of the short fiber and the atomized liquid, thereby improving the liquid guiding rate of the liquid guiding body 1, reducing the risk that the liquid guiding body 1 is damaged by the heating component 2 due to the smaller liquid guiding rate of the liquid guiding body 1, prolonging the service life of the liquid guiding body 1, and simultaneously reducing the risk that the liquid guiding rate of the liquid guiding body 1 cannot meet the use requirement due to the smaller liquid guiding rate of the liquid guiding body 1, thereby improving the working efficiency of the liquid guiding body 1.

The applicant selects the short fiber materials existing in the market to prepare the liquid guide body 1 with an integrated structure, specifically comprises a first liquid guide body, a second liquid guide body, a third liquid guide body, a fourth liquid guide body, a fifth liquid guide body and a sixth liquid guide body which are different in material, layer number and thickness, selects the short fiber materials to prepare a first comparison liquid guide body and a third comparison liquid guide body which are single layers, and selects the long fiber materials to prepare a second comparison liquid guide body with three layers of spunlaced non-woven fabrics stacked, wherein the preparation method is the prior art and is not described in detail; the prepared samples were tested by the following method, and the test results are shown in Table 1, wherein "A" represents the first layer 11, "B" represents the second layer 12, and "C" represents the third layer 13.

In measuring the thicknesses of the 6 liquid guides 1 and 3 liquid guides, the 6 liquid guides 1 and 3 liquid guides were placed in a measuring space of a thickness gauge, respectively, and the liquid guides were held by the thickness gauge for testing, and data shown in table 1 were obtained.

When the grammage of the 6 liquid guides 1 and 3 comparative liquid guides was measured, the 6 liquid guides 1 and 3 comparative liquid guides were divided into a plurality of liquid guide blocks of unit volume, and the weights of the liquid guide blocks were measured, and data shown in table 1 were obtained.

When the gram weight tolerance of the 6 liquid guides 1 and 3 comparison liquid guides is measured, the 6 liquid guides 1 and 3 comparison liquid guides are respectively divided into a plurality of liquid guide blocks with unit volumes, the weights of the plurality of mass blocks are respectively measured, and the gram weight tolerance is calculated according to the following formula: maximum tolerance= (maximum value-average value)/average value × 100%, minimum tolerance= (minimum value-average value)/average value × 100%, and data shown in table 1 were obtained after calculation.

When the liquid absorption rates of the 6 liquid guides 1 and 3 comparative liquid guides were measured, the 6 liquid guides 1 and 3 comparative liquid guides were divided into a plurality of liquid guide blocks of unit volume, the original weights of the liquid guide blocks were measured, the liquid guide blocks were immersed in a standard liquid (the standard liquid was a mixture of ethylene glycol and glycerol in a mass ratio of 1:1), the weights of the standard liquid absorbed by the liquid guide blocks were measured, the liquid absorption rates of the liquid guides were calculated from the ratio of the weight of the standard liquid absorbed to the original weight, and the data shown in table 1 were obtained.

When the liquid guiding rates of the 6 liquid guiding bodies 1 and 3 comparison liquid guiding bodies were measured, the standard liquid was dropped onto the 6 liquid guiding bodies 1 and 3 comparison liquid guiding bodies, respectively, the liquid guiding amounts of the liquid guiding bodies per unit time were calculated, and the data shown in table 1 were obtained.

In measuring the surface structures of the above 6 liquid guides (taking the first liquid guide as an example), the first liquid guide is placed under a microscope to observe, and a magnified view of the microscope as shown in fig. 10 is obtained.

TABLE 1 Performance parameter Table for liquid guides

Note that: american cotton (cotton fiber) is one of natural cellulose fibers, and flax fiber (hemp fiber) is one of regenerated cellulose fibers.

As can be seen from table 1, the first liquid guide of example 1 is made of the first layer 11 and the second layer 12 having different fiber lengths (i.e., as shown in fig. 6), the second liquid guide of example 2 is made of the first layer 11 and the second layer 12 having different materials (i.e., as shown in fig. 6), and the third liquid guide of example 3 is made of the first layer 11, the second layer 12 and the third layer 13 having different materials (as shown in fig. 7), but as can be seen from fig. 10, 11 and 12, the first layer 11 is interwoven with the second layer 12, the second layer 12 and the third layer 13, and no boundary line is seen from a microscopic view. As can be seen from fig. 14, the second comparative liquid guide of comparative example 2 is a three-layer separated structure, and the risk that the second comparative liquid guide of the three-layer separated structure is easily separated from layer to layer during processing, installation, transportation, use, etc. is more stable than the liquid guide 1 integrally formed in examples 1 to 6, and therefore, the structure of the liquid guide 1 integrally formed in examples 1 to 6 of the present application is more stable.

As can be readily seen from the data in table 1: (1) The liquid guides 1 in examples 1 to 6 were each made of the first layer body and the second layer body (and the third layer body), and when the thicknesses of the first layer body and the second layer body (and the third layer body) were each smaller, processing of the thinner liquid guide 1 was facilitated (i.e., examples 1 to 4), and when the thicknesses of the first layer body and the second layer body (and the third layer body) were each larger, processing of the thicker liquid guide 1 was facilitated (i.e., examples 5 and 6), whereas the first comparative liquid guide in comparative example 1 and the third comparative liquid guide in comparative example 3 were each made of a single layer of fibers, and processing difficulty was greater than that of the multilayer liquid guides 1 in examples 1 to 6. Therefore, the liquid guide body 1 is made of at least the first layer 11 and the second layer 12, and the processing difficulty of the liquid guide body 1 can be reduced. (2) The liquid guiding body 1 is an integral structure formed by interweaving short fibers with different materials or short fibers with different lengths into two or more layers, and the gram weight tolerance delta M1 of the liquid guiding body 1 meets the following conditions: 8% or less Δm1% or less +8% while the gram weight tolerance Δm2 of the second comparison liquid of comparative example 2 satisfies: -13% or more and delta M2% or less and +13% or less. Compared with the mode of multilayer superposition in the prior art, the thickness and the gram weight of the liquid guide body 1 of the integrated structure are uniform, the deviation of the thickness and the gram weight of each part of the liquid guide body 1 is reduced, and therefore the liquid guide uniformity of the liquid guide body 1 is improved. (3) The liquid transfer rate of liquid transfer 1 in examples 1 to 6 is significantly higher than that of the comparative example; from the data of example 1 and comparative example 2 in particular, it can be seen that: when all the American cotton fibers are selected, the liquid guiding rate of the first liquid guiding body formed by interweaving the short fibers is far higher than that of the second comparison liquid guiding body made of long fibers; the short fiber is selected to greatly improve the capillary porosity of the adjacent fiber, and the fluff on the surface of the fiber is selected to greatly improve the liquid guiding rate of the liquid guiding body 1. (3) As can be seen from the data in example 1 and comparative example 1, the first liquid guiding body with the integrated structure is made by layering fibers with different lengths, and a good balance is obtained between the liquid absorption rate and the liquid guiding rate, that is, the second layer 12 (i.e., layer B) where the second short fibers 121 with larger length are located has a better liquid guiding rate, and the first layer 11 (i.e., layer a) where the first short fibers 111 with smaller length are located has a better liquid absorption rate, so that the whole first liquid guiding body can be ensured to have better liquid leakage preventing and liquid guiding performance.

As can be seen from the data in table 1: in the second liquid guide of example 2, natural cellulose fibers (american cotton) were selected as the first layer 11 of the second liquid guide, regenerated cellulose fibers (50% viscose fibers and 50% asahi-formation fibers were mixed) were selected as the second layer 12 of the second liquid guide, and when the heating member 2 was mounted on the end face of the first layer 11 of the second liquid guide, 2ml of atomized liquid was atomized in the atomizer, and as shown in fig. 13, the surface of the second liquid guide was still intact and no scorching occurred; however, in comparative example 3, a single-layer third comparative liquid prepared from regenerated cellulose fibers (viscose fibers) was used, and after atomizing 2ml of the atomized liquid under the same conditions, as shown in fig. 15, the surface of the third comparative liquid was partially burned. This shows that the double-layer integrated liquid guide 1 obtained by selecting the natural cellulose fibers and the regenerated cellulose fibers has better high-temperature resistance effect.

In summary, compared with the liquid guide 1 with the multi-layer structure prepared by long fibers, the liquid guide 1 with the integrated structure formed by interweaving short fibers has better liquid guide speed and liquid guide uniformity, and the liquid guide with the integrated structure with the double-layer or multi-layer structure has better temperature resistance.

The liquid guide 1 has an atomizing surface 15 and a liquid guide surface 14 which are arranged opposite to each other, and may be prepared in any shape, as shown in fig. 3, and the liquid guide 1 may have a polygonal structure (for example, a rectangular parallelepiped, a square or other deformed structure, and fig. 2 illustrates the liquid guide 1 as a rectangular structure) so as to facilitate connection of the liquid guide 1 and the heating member 2. In another embodiment, as shown in fig. 4, the liquid guiding body 1 may be bent into a V-shaped structure, a U-shaped structure or other deformed structures, and in another embodiment, as shown in fig. 5, the liquid guiding body 1 is enclosed into a tubular structure, so as to promote the flexibility of the structure of the liquid guiding body 1.
