[0002] An electronic atomizer generates aerosol for consumers to inhale through an atomization component. The atomization component heats the atomization liquid adsorbed by a heating wire to generate aerosol. The power that the atomization component can withstand is crucial for improving the taste of the electronic atomizer. The existing methods for increasing the power of the atomization component of an electronic atomizer mostly involve reducing the resistance value of the heating wire or adopting a form of assembling multiple atomization components. These methods all have their drawbacks. For example, reducing the resistance value of the heating wire will lead to a decrease in energy use efficiency, and the form of assembling multiple atomization components will cause an increase in cost. When maintaining the existing resistance value of the heating wire and using the existing liquid guiding element, after increasing the power of the atomization component, due to the high viscosity and poor fluidity of the e-liquid, the liquid supply is insufficient, there is an obvious burnt smell, and it is easy to cause the atomization component to fail. Summary of the Invention

[0033] As used herein, the terms:

[0034] "Prepared from" is synonymous with "comprising". As used herein, the terms "comprising", "including", "having", "containing" or any other variation thereof are intended to cover non - exclusive inclusion. For example, a composition, step, method, article or device comprising the listed elements is not necessarily limited to those elements, but may include other elements not expressly listed or elements inherent to such composition, step, method, article or device.

[0035] The connective "consisting of" excludes any unrecited element, step, or component. If used in a claim, this phrase renders the claim closed-ended, excluding materials other than those recited, except for conventional impurities associated therewith. When the phrase "consisting of" appears in a clause within the body of a claim rather than immediately following the subject, it limits only the elements recited in that clause; other elements are not excluded from the claim as a whole.

[0036] When an equivalent, concentration, or other value or parameter is expressed as a range, a preferred range, or a range defined by a series of upper preferred values and lower preferred values, it should be understood that all ranges formed by any pairing of any upper range limit or preferred value with any lower range limit or preferred value are specifically disclosed, whether or not the ranges are separately disclosed. For example, when the range "1-5" is disclosed, the described range should be interpreted as including the ranges "1-4", "1-3", "1-2", "1-2 and 4-5", "1-3 and 5", etc. When a numerical range is described herein, unless otherwise specified, the range is intended to include its end values and all integers and fractions within the range.

[0037] In these examples, unless otherwise specified, the parts and percentages are by mass.

[0038] "Parts by mass" refers to the basic measurement unit representing the mass ratio relationship of multiple components. 1 part can represent any unit mass, such as 1 g or 2.689 g, etc. If we say that the mass parts of component A is a parts and the mass parts of component B is b parts, it means the mass ratio of component A to component B is a:b. Or, it means the mass of component A is aK and the mass of component B is bK (K is any number representing a multiple factor). It should not be misunderstood that, different from the number of mass parts, the sum of the mass parts of all components is not limited to 100 parts.

[0039] "And / or" is used to indicate that either or both of the stated circumstances may occur. For example, A and / or B includes (A and B) and (A or B).

[0040] After the existing electronic atomizer further increases the normal power to the excess power, for example, the normal power of the atomization component can be maintained at 10-12 w. After the working power of the atomization component exceeds 15 w, the viscosity of the atomization matrix will increase, resulting in poor fluidity, leading to insufficient oil supply during suction, and thus generating a burnt smell.

[0041] In this application, a combination of a metal mesh and a conventional liquid guide is selected. By increasing the thermal conductivity of the liquid guide block, the heat transfer from the heating element to the atomization matrix during operation is accelerated, thereby reducing the viscosity of the atomization matrix and improving the fluidity of the atomization matrix, that is, increasing the liquid guiding rate, so that the maximum power that the atomization component of this application can withstand is increased by more than 75% compared with the conventional atomization component.

[0042] In some embodiments, please refer to Figure 1 and Figure 2 , Figure 1 , which is the tiled structure of the liquid guiding element 10, Figure 2 , which is the overall structure of the liquid guiding element 10. The liquid guiding element 10 of this application includes: at least two layers of liquid guides 12 and at least one layer of metal mesh 14 arranged in a stacked manner; the liquid guiding element 10 is cylindrical, with liquid guides 12 on both the inner and outer sides of the liquid guiding element 10, and the liquid guides 12 and the metal mesh 14 are alternately stacked.

[0043] Among them, the liquid guide 12 is used to adsorb the atomization liquid in the electronic atomizer and conduct the liquid. Therefore, the material used to prepare the liquid guide 12 needs to have liquid absorption and liquid conduction properties. The liquid guide 12 can be, for example, oil guiding cotton and / or a porous ceramic body. Moreover, at least two layers of liquid guides 12 can be arranged adjacent to each other. For example, the liquid guide 12 of this application can be a cotton sheet with long and thick fibers. The long fiber cotton sheet has better liquid absorption ability, and the thick fiber cotton sheet has better liquid conduction ability. The material of the liquid guide 12 can also be non-woven fabric, or wood fiber, etc. This application does not make specific limitations. The shape of the liquid guide 12 is sheet-like, and the number of layers of the liquid guide 12 can be, for example, two layers, three layers, four layers, five layers, six layers, seven layers, eight layers or more layers. Figure 1 The number of layers of the liquid guide 12 of the liquid guiding element 10 shown in is five layers.

[0044] The metal mesh 14 can be a metal wire woven metal mesh sheet, or a metal sheet with multiple mesh holes. Preferably, it is a metal sheet with multiple mesh holes. The mesh holes can be of different shapes, such as triangular ( Figure 3 ), circular ( Figure 4 ), quadrilateral ( Figure 5 and Figure 6 ), hexagonal ( Figure 7 ) or other special-shaped shapes ( Figure 8 ), or a combination of the above shapes ( Figure 8 ); the number of mesh holes per unit area can be arbitrary. The metal mesh sheet can be prepared by stamping process or etching process. To ensure continuous production, the stamping process is preferably selected. After stamping, mesh holes are formed, and it can also be further processed by sandblasting process to remove the surface burrs of the metal mesh sheet, so that the metal mesh 14 and the liquid guide 12 can be closely attached.

[0045] The mesh holes on the metal mesh 14 are the channels for the atomization liquid and aerosol in the electronic atomizer. Therefore, the metal mesh 14 also has the function of liquid conduction. The non-mesh part of the metal mesh 14 plays the role of heat transfer, which can improve the thermal conductivity of the liquid guide block 12 stacked with the metal mesh 14. The faster the liquid guide 12 conducts heat, the faster the heat can be transferred to the atomization liquid, thereby reducing the viscosity of the atomization liquid and increasing the fluidity of the atomization liquid, that is, increasing the liquid conduction rate. The metal mesh 14 can be, for example, one layer, two layers, three layers, four layers, five layers, six layers or more layers. Figure 1 The number of layers of the metal mesh 14 of the liquid guide element 10 shown is two layers.

[0046] Among them, please refer to Figure 2 , the overall shape of the liquid guide element 10 is cylindrical, that is, the stacked liquid guide 12 and metal mesh 14 are curled into a cylindrical shape, which can be, for example, a cylindrical shape, or other shapes that match the structure of the atomization device. The inner side of the liquid guide element 10 is the side close to the center of the cylinder, and the outer side of the liquid guide element 10 is the outermost side. And both the inner side and the outer side of the liquid guide element 10 are the liquid guide 12, so as to ensure that the liquid guide 12 is in contact with the heating element instead of the metal mesh 14, preventing the heating element from short-circuiting, and setting the liquid guide 12 on both the inner side and the outer side can also prevent the liquid guide element 10 from leaking liquid.

[0047] It should be noted that the liquid guide 12 and the metal mesh 14 of the liquid guide element 10 are alternately stacked. It can be an alternating manner of one layer of liquid guide 12 and one layer of metal mesh 14, or an alternating manner of one layer of metal mesh 14 and multiple layers of liquid guide 12, or it can be two or three layers of metal mesh 14 stacked together and then alternated with one or more layers of liquid guide 12.

[0048] In some embodiments, the metal mesh 14 is at least two layers, for example, it can be two layers, three layers, four layers, five layers, six layers or more layers; at most two adjacent metal meshes are arranged among the at least two metal meshes, or at least one layer of liquid guide is arranged on both sides of each layer of metal mesh.

[0049] For example, when the metal mesh is two layers, the two metal meshes can be arranged adjacent to each other, so that there is no liquid guide between the two metal meshes, and as a whole, one layer, two layers, three layers or more layers of liquid guide are independently arranged on both sides of the two metal meshes. It can be understood that when the number of layers of the liquid guide on both sides of the two adjacent metal meshes is one layer, it can be the innermost or outermost layer of the liquid guide. When the metal mesh is two layers, the two metal meshes can also be arranged at intervals, that is, one layer, two layers, three layers or more layers of liquid guide are arranged between the two metal meshes, so that one layer, two layers, three layers or more layers of liquid guide are arranged on both sides of each layer of metal mesh. It can be understood that other liquid guides can be arranged between the metal mesh and the innermost or outermost layer of the liquid guide, or no other liquid guides can be arranged.

[0050] For another example, when the metal mesh has three layers, the metal meshes of each layer can be arranged at intervals, that is, one, two, three or more layers of liquid conductors are independently arranged between the metal meshes of each layer. Or, among the three metal meshes, two of them can be arranged adjacent to each other, and the other one is arranged separately. One, two, three or more layers of liquid conductors are arranged between the two adjacent metal meshes and the separately arranged metal mesh. Among them, the two adjacent metal meshes can be close to the innermost liquid conductor or the outermost liquid conductor.

[0051] For yet another example, when the metal mesh has four layers, the metal meshes of each layer can be arranged at intervals, that is, one, two, three or more layers of liquid conductors are independently arranged between the metal meshes of each layer; or, among the four metal meshes, two of them can be arranged adjacent to each other, and the other two are also arranged adjacent to each other. One, two, three or more layers of liquid conductors are arranged between the two adjacent metal meshes. Among them, one of the two adjacent metal meshes is close to the innermost liquid conductor, and the other is close to the outermost liquid conductor; or, among the four metal meshes, two of them can be arranged adjacent to each other, and the other two are arranged separately and at intervals. One, two, three or more layers of liquid conductors are independently arranged between the two adjacent metal meshes and the metal meshes arranged separately and at intervals. Among them, the two adjacent metal meshes can be close to the innermost liquid conductor, or the outermost liquid conductor, or the middle two layers of the four metal meshes.

[0052] And so on, when the metal mesh has five layers, six layers or more layers, the same principle applies. Among all the metal meshes, liquid conductors should be arranged between the metal meshes. The metal meshes can be arranged in a single layer, and at most two metal meshes can be arranged adjacent to each other. Although the power will be higher when multiple metal meshes are arranged adjacent to each other, it is easy to slide during processing. Therefore, at most two metal meshes are arranged adjacent to each other, and it is not easy to process when more than two metal meshes are arranged adjacent to each other.

[0053] In some embodiments, the liquid guide 12 on the inner or outer side of the liquid guiding element 10 contacts the heating element. When the heating element is vertically arranged, the liquid guide on the inner side of the liquid guiding element 10 contacts the heating element. When the heating element is horizontally arranged, the liquid guide on the outer side of the liquid guiding element 10 contacts the heating element. The thickness of the liquid guide contacting the heating element is 0.1 - 1.0 mm. For example, it can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm or any value between 0.1 - 1.0 mm. If the thickness of the liquid guide contacting the heating element is too small, the risk of short - circuit of the heating element will increase. If the thickness is too large, the thermal conductivity coefficient will become smaller, affecting the delivery of the atomized liquid when the heating element works. The thickness of the liquid guide contacting the heating element is preferably 0.2 - 0.8 mm, and more preferably 0.3 - 0.6 mm. It can be understood that the liquid guide contacting the heating element can be only the inner or outer liquid guide, or can include other liquid guides adjacent to the inner or outer liquid guide, mainly determined by the thickness of the single - layer liquid guide. If the thickness of the single - layer liquid guide is relatively thin, the liquid guide contacting the heating element is set as multiple layers.

[0054] In some embodiments, in order to achieve a better heat transfer effect, the total mesh area of the metal mesh accounts for 50 - 80% of the total area of the metal mesh. For example, it can be 50%, 55%, 60%, 65%, 70%, 75%, 80% or any value between 50 - 80%. If the mesh area is too low, the liquid guiding performance of the metal mesh is poor. If the mesh area is too high, the heat conduction performance of the metal mesh is poor. The mesh area within the scope of this application can balance the liquid guiding performance and the heat conduction performance.

[0055] In some embodiments, the material of the metal mesh is a food - grade material, including but not limited to food - grade stainless steel materials, silver, copper, gold, aluminum, tungsten, iron, platinum, titanium metals and other materials. Preferably, the material of the metal mesh is stainless steel material or copper, and their costs are relatively low. More preferably, the material of the metal mesh is copper, and its heat conduction performance is better than that of stainless steel.

[0056] In some embodiments, the thickness range of the metal sheet for preparing the metal mesh is 0.03 - 0.5 mm. For example, it can be 0.03 mm, 0.05 mm, 0.08 mm, 0.1 mm, 0.12 mm, 0.15 mm, 0.17 mm, 0.19 mm, 0.2 mm, 0.22 mm, 0.24 mm, 0.25 mm, 0.28 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm or any value between 0.03 - 0.5 mm. To ensure the stability of the atomized liquid delivery, the thickness of the metal mesh is preferably 0.05 mm - 0.3 mm, and more preferably 0.05 mm - 0.2 mm.

[0057] The present application also provides an atomization component. Please refer to Figure 9 and Figure 10 , the atomization component 100 includes a housing 20 and a mounting base 30 detachably connected to the housing 20. A receiving space is formed between the housing 20 and the mounting base 30. The liquid guiding element 10 and the heating element 40 as described above are arranged in the receiving space. The liquid guiding element 10 is used to adsorb the atomization matrix and transport it to the heating element 40, and the atomization component 100 is used to atomize the atomization matrix into aerosol.

[0058] The present application also provides an atomization device, which includes the above-mentioned atomization component 100 and a power supply component. The power supply component is used to supply electric energy to the atomization component 100, and the atomization component 100 is used to heat the atomization matrix into aerosol. The atomization device can be a disposable product or a cartridge replacement type product. For a disposable atomization device, the atomization component 100 and the power supply component are fixedly connected; for a cartridge replacement type atomization device, the atomization component 100 and the power supply component are detachably connected, and the atomization component 100 and the power supply component can be replaced according to the usage situation.

[0059] The present application also provides a preparation system for the liquid guiding element as described above, including: a cutting device, used to stack the liquid guiding body and the metal mesh in a preset manner in sequence and perform cutting processing; a hydraulic device, used to flatten the cut liquid guiding body and metal mesh; a rolling device, used to roll the flattened liquid guiding body and metal mesh into a cylindrical shape to obtain the liquid guiding element.

[0060] Among them, the cutting device can be a stamping device for example; the hydraulic device can ensure that the metal mesh and the liquid guiding body are flat and tightly attached. The pressure range of the hydraulic device can be 1 to 10 MPa for example; the rolling device can be an automatic cotton wrapping machine for example.

[0061] In one embodiment, the preparation system for the liquid guiding element further includes: a stamping device or an etching device, used to produce the metal mesh. To ensure continuous production, the preferred solution is a stamping device.

[0062] In one embodiment, the preparation system for the liquid guiding element further includes: a sandblasting device, used to process the surface of the metal mesh, perform sandblasting treatment on it to solve the problem of surface burrs and make it fit tightly with the liquid guiding body.

[0063] The present application also provides a preparation method for the liquid guiding element as described above. Please refer to Figure 11 , including:

[0064] Step S100: Stack the liquid guiding body and the metal mesh in a preset manner in sequence and perform cutting processing.

[0065] Among them, a stamping device can be used for cutting. The metal mesh and the liquid guide are selected in the form of coil materials and placed on rotatable material trays at different heights. The stacking quantity of the metal mesh and the liquid guide is the same as the number of material trays. Figure 12 There are 5 groups of material trays. In actual production, the number of trays can be set according to the number of layers of the metal mesh and the liquid guide, such as 6 groups, 7 groups, 8 groups, etc. The materials converge on the stamping device through the traction rollers for stacking and cutting. The liquid guide and the metal mesh are stacked in sequence according to the preset manner of the above liquid guiding element.

[0066] Before step S100, it also includes: manufacturing the metal mesh by using a stamping process or an etching process; among them, to ensure continuous production, the preferred solution is the stamping process. And, after manufacturing the metal mesh by using the stamping process, it also includes: treating the surface of the metal mesh by using a sandblasting process. The metal mesh is prepared by stamping, and after stamping, sandblasting treatment is also required to solve the problem of surface burrs and make it fit tightly with the liquid guide.

[0067] Step S200: Use a hydraulic device to flatten the cut liquid guide and metal mesh.

[0068] After the liquid guide and the metal mesh are stamped and cut, the metal mesh will be deformed to a certain extent. To ensure that the metal mesh fits flatly and tightly with the liquid guide, the cut liquid guide and metal mesh need to be flattened on a hydraulic device, and the pressure range is 1 - 10 MPa. For example, it can be 1 MPa, 2 MPa, 3 MPa, 4 MPa, 5 MPa, 6 MPa, 7 MPa, 8 MPa, 9 MPa or 10 MPa.

[0069] Step S300: Roll the flattened liquid guide and metal mesh into a cylinder to obtain the liquid guiding element.

[0070] The preparation method of the liquid guiding element of the present application only needs to add a set of hydraulic equipment, and then continuous batch production can be realized by means of the existing liquid guide production equipment. The operation is simple, the cost is low, and there is no need to transform the existing production line on a large scale.

[0071] The following will describe the implementation scheme of the present application in detail with specific embodiments. However, those skilled in the art will understand that the following embodiments are only used to illustrate the present application and should not be regarded as limiting the scope of the present application. For those not specified in the embodiments, they are carried out according to the conventional conditions or the conditions recommended by the manufacturer.

[0114]

[0115]

[0116] As can be seen from Table 1, for the atomizing device using the liquid guiding element of the solution of the present application, without the taste being abnormal or burnt, the maximum power that the atomizing device of the solution of the present application can withstand and the amount of smoke per puff are both higher than those of the comparative example solution, indicating that the liquid guiding rate of the liquid guiding element of the solution of the present application is faster. And it can be seen from Examples 1 to 3 that as the number of layers of the metal mesh increases, the maximum power that the atomizing device can withstand and the amount of smoke per puff increase accordingly; it can be seen from Examples 3 to 5 that within the scope of the present application, as the mesh area of the metal mesh increases, the maximum power that the atomizing device can withstand and the amount of smoke per puff increase accordingly; moreover, the maximum power that the atomizing device with a copper mesh can withstand and the amount of smoke per puff are also increased compared with the atomizing device with a stainless steel mesh, because the thermal conductivity of steel is better. However, in Comparative Example 2, due to the too low mesh area, the liquid guiding performance of the liquid guiding element is affected, and the core will be burnt after 10 puffs at a power of 14 w; in Comparative Example 3, due to the too large mesh area, the thermal conductivity of the liquid guiding element becomes correspondingly poor.
