Description

Technical Field

[0001] This invention relates to the field of electronic atomization technology, and more specifically, to an atomizing core with a liquid-guiding fiber sheet and an electronic atomization device. Background Technology

[0002] Electronic atomizing devices are electronic products that atomize an aerosol-generating liquid to produce an aerosol for users to inhale. The aerosol-generating liquid can be water, fragrances, or medicinal liquids, among other things. They have a wide range of applications, including air conditioning and disease treatment. Existing electronic atomizing devices include a housing containing a liquid reservoir, an atomizing coil, a battery, and an airflow sensor. The atomizing coil, located within the liquid reservoir, atomizes the liquid inside to form an aerosol.

[0003] Existing atomizing cores typically include a fixed tube, a heating element, and a liquid-guiding fiber sheet. The fixed tube has a strip-shaped notch on its side wall. The heating element is located inside the fixed tube, and the liquid-guiding fiber sheet covers the heating element, with its first and second ends extending from a clamping opening. During assembly, the liquid-guiding fiber sheet is first placed over the heating element, and then the liquid-guiding fiber sheet, covered by the heating element, is aligned with the inner cavity and notch of the fixed tube and inserted into the fixed tube.

[0004] However, because the notch is a narrow strip, the friction between the notch and the lower side of the liquid-guiding fiber sheet is prolonged during the assembly process, causing the edge of the liquid-guiding fiber sheet to lift up, creating a gap between the liquid-guiding fiber sheet and the fixed tube, resulting in poor sealing and easy leakage.

[0005] The above-mentioned defects urgently need to be addressed. Summary of the Invention

[0006] To address the problem of leakage caused by gaps in the fixing tubes of existing atomizing cores, this invention provides an atomizing core with a liquid-guiding fiber sheet and an electronic atomizing device.

[0007] The technical solution of this invention is as follows:

[0008] In a first aspect, the solution of the present invention to the above-mentioned problems is to construct an atomizing core with a liquid-guiding fiber sheet, comprising:

[0009] A fixed tube is provided with a notch and several spaced liquid guiding holes on its side wall. The notch includes a first guide port, a second guide port and a clamping port. The first guide port is connected to the first end face of the fixed tube, the first end of the second guide port is connected to the first guide port, and the second end of the second guide port is connected to the clamping port. The diameter of the first guide port and the diameter of the second guide port gradually increase along the direction from the second end face of the fixed tube to the first end face of the fixed tube.

[0010] The heating element is located inside the fixed tube and corresponds to the position of the notch.

[0011] A liquid-conducting fiber sheet is wrapped around the heating element and covers the opening of the liquid-conducting hole. The first end and the second end of the liquid-conducting fiber sheet extend from the clamping port, which clamps the liquid-conducting fiber sheet. The porosity of the liquid-conducting fiber sheet at the clamping port is less than the porosity of the rest of the liquid-conducting fiber sheet.

[0012] Preferably, the thermal conductivity of the region corresponding to the liquid guiding hole of the heating element is greater than the thermal conductivity of the remaining regions of the heating element.

[0013] Preferably, the heating element includes a heating part and a heat-conducting part. The heating part is provided with a plurality of rhomboid atomizing holes, and heating arms are formed between the atomizing holes. The heat-conducting part is connected to the heating part, and the liquid guiding hole corresponds to the position of the heating arm.

[0014] Preferably, the capillary force at the lower end of the liquid-guiding fiber sheet is greater than the capillary force at the upper end of the liquid-guiding fiber sheet.

[0015] Preferably, the distance between the outer openings of the second guide opening is smaller than the distance between the inner openings of the second guide opening.

[0016] Preferably, the first guide port is flared in the orthographic projection of the longitudinal section of the fixed tube, and the second guide port is trapezoidal in the orthographic projection of the longitudinal section of the fixed tube.

[0017] Preferably, the clamping opening extends longitudinally along the fixing tube, and the orthographic projection of the clamping opening onto the longitudinal section of the fixing tube is rectangular.

[0018] Preferably, the atomizing core with liquid-guiding fiber sheet further includes a positioning post and a wire. The positioning post is inserted into the second end of the fixing tube. The first end of the wire is clamped between the positioning post and the fixing tube and connected to the heating element. The second end of the wire extends outside the fixing tube.

[0019] Preferably, a positioning hole is also provided on the side wall of the second end of the fixed tube, the positioning hole being used to identify the fixed tube during assembly.

[0020] Secondly, the present invention also discloses an electronic atomizing device, including a housing and an atomizing core. The housing is provided with a liquid storage chamber for storing atomizing liquid, and the atomizing core is located in the liquid storage chamber for atomizing the atomizing liquid in the liquid storage chamber. The atomizing core is an atomizing core with a liquid guiding fiber sheet as described in any of the first aspects above.

[0021] According to the above-described solution, the beneficial effects of this invention are as follows:

[0022] Firstly, since the notch includes a first guide port, a second guide port, and a clamping port connected end to end, the diameters of the first guide port and the second guide port gradually increase along the direction from the second end face of the fixed tube to the first end face of the fixed tube. Therefore, during assembly, the operator does not need to worry about misalignment; they can simply push the first and second ends of the liquid-guiding fiber sheet from the first guide port to the clamping port, avoiding the problem of the heating element being squeezed, which would affect the resistance value of the heating element. As a result, the aerosol has a good taste when inhaled by the user.

[0023] Secondly, by setting a second guide port, the length of the clamping port is shortened, thus reducing the friction time between the notch and the lower side of the liquid guiding fiber sheet during assembly. This avoids the problem of the liquid guiding fiber sheet lifting due to long friction time during assembly, which would create a gap between the liquid guiding fiber sheet and the fixed tube, resulting in poor sealing and leakage.

[0024] Finally, since the porosity of the fluid-conducting fiber sheet at the clamping opening is less than that of the rest of the fluid-conducting fiber sheet, the strength and wear resistance of this area are increased, greatly improving the sealing performance and reducing the risk of oversaturation in the area of ​​the fluid-conducting fiber sheet located inside the fixed tube.

[0032] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] See Figures 1 to 4 This invention provides an atomizing core with a liquid-guiding fiber sheet for use in electronic atomizing devices. The atomizing core includes a fixing tube 1, a heating element 2, a liquid-guiding fiber sheet 3, a positioning post 4, and a wire 5. The side wall of the fixing tube 1 is provided with a positioning hole 11, a notch 12, and several liquid-guiding holes 13. The fixing tube 1 has a first end and a second end positioned opposite each other. The second end of the fixing tube 1 is used to connect to the fixing seat 204 of the electronic atomizing device 200 to fix the atomizing core 100. The positioning hole 11 is located on the side wall of the second end of the fixing tube 1 and is used to identify the fixing tube 1 during assembly, serving as a position marker. By providing this positioning hole 11, production efficiency can be improved.

[0034] The notch 12 extends along the longitudinal direction of the fixing tube 1 and includes a first guide port 121, a second guide port 122, and a clamping port 123 connected end to end. The first guide port 121 communicates with the first end face of the fixing tube 1, that is, the first end face of the fixing tube 1 is recessed towards the second end of the fixing tube 1 to form the first guide port 121, and the edge of the first guide port 121 is arc-shaped. The first end of the second guide port 122 communicates with the first guide port 121, and the second end of the second guide port 122 communicates with the clamping port 123. The first guide port 121, the second guide port 122, and the clamping port 123 all extend along the longitudinal direction of the fixing tube 1.

[0035] Along the direction from the second end face of the fixed tube 1 to the first end face of the fixed tube 1, the diameters of the first guide port 121 and the second guide port 122 gradually increase. Therefore, during assembly, the operator does not need to worry about misalignment or excessive friction of the notch 12 on the liquid-guiding fiber sheet 3. They can simply push the first and second ends of the liquid-guiding fiber sheet 3 from the first guide port 121 to the clamping port 123, thus improving assembly efficiency.

[0036] The distance between the outer openings of the second guide ports 122 is smaller than the distance between the inner openings of the second guide ports 122. That is, at the same radial position, the distance between the second guide ports 122 located on the outer circumferential surface of the fixed tube 1 is smaller than the distance between the second guide ports 122 located on the inner circumferential surface of the fixed tube 1. Therefore, during assembly, the side of the fluid-guiding fiber sheet 3 is less likely to be subjected to frictional force from the second guide ports 122, or the frictional force received is smaller, avoiding warping due to friction. Figure 4As shown, in this embodiment, the distance between the outer openings of the second guide port 122 and the first guide port 121 is L1, and the distance between the inner openings of the second guide port 122 and the first guide port 121 is L2, wherein L1 is less than L2.

[0037] The first guide port 121, when projected onto the longitudinal section of the fixed tube 1, is trumpet-shaped, while the second guide port 122, when projected onto the longitudinal section of the fixed tube 1, is trapezoidal. Therefore, during assembly, the side of the fluid-guiding fiber sheet 3 is not subjected to frictional forces from the first guide port 121 and the second guide port 122, preventing it from warping due to friction and creating a gap between the fluid-guiding fiber sheet 3 and the fixed tube 1, resulting in poor sealing and leakage. Preferably, the length of the second guide port 122 is not less than one-third of the length of the clamping port 123, and the width of the fluid-guiding fiber sheet 3 is equal to the length of the clamping port 123. In other words, the length of the second guide port 122 is made as long as possible to reduce the frictional force between the second guide port 122 and the fluid-guiding fiber sheet 3 during assembly. It is understood that the longitudinal section mentioned in this embodiment refers to the section perpendicular to the cross-section of the fixed tube 1 and perpendicular to the opening direction of the notch 12.

[0038] The clamping port 123 extends longitudinally along the fixing tube 1. The orthographic projection of the clamping port 123 onto the longitudinal section of the fixing tube 1 is rectangular, which facilitates assembly and allows for effective clamping of the fluid-guiding fiber sheet 3. The length of the clamping port 123 is greater than the length of the second guide port 122, and the width of the clamping port 123 is less than the width of the second guide port 122. This avoids the problem of low assembly efficiency and incomplete assembly caused by an excessively long second guide port 122.

[0039] Several liquid guiding holes 13 are arranged at intervals around the side wall of the fixed tube 1. The liquid guiding holes 13 and the clamping port 123 are located at the same axial position. The distance between the clamping port 123 and its adjacent liquid guiding hole 13 is equal to the distance between the adjacent liquid guiding holes 13. Therefore, the liquid supply is more uniform and the probability of dry burning is reduced.

[0040] The heating element 2 is located inside the fixed tube 1 and corresponds to the position of the notch 12. It is used to atomize the atomized liquid at the liquid-guiding fiber sheet 3. The heating element 2 includes a heating part 21 and a heat-conducting part 22. The heating part 21 is provided with a plurality of rhomboid atomizing holes 23, and heating arms 231 are formed between the atomizing holes 23. The heat-conducting part 22 is connected to the heating part 21. The liquid guiding holes 13 correspond to the positions of the heating arms 231, thus effectively avoiding the problem of insufficient atomized liquid supply and dry burning when the liquid guiding holes 13 and the heating arms 231 are misaligned. Specifically, there are several heat-conducting parts 22, which are located at the upper and lower ends of the heating part 21, and are spaced apart. It can be understood that during operation, the heating part 21 is heated by electric current, and the heat-conducting part 22 absorbs the heat from the heating part 21 and atomizes the atomized liquid. In this embodiment, the thermal conductivity of the heating arm 231 is greater than that of the heat-conducting part 22.

[0041] The liquid-guiding fiber sheet 3 covers the heating element 2 and the opening of the liquid-guiding hole 13, thus absorbing the atomized liquid flowing in through the liquid-guiding hole 13. The first and second ends of the liquid-guiding fiber sheet 3 extend from the clamping port 123, which clamps the liquid-guiding fiber sheet 3, thus reliably fixing it in place. The liquid-guiding fiber sheet 3 can be made of synthetic or natural fibers. It can be made of one or more layers of cotton, and its structure is not specifically limited, as long as it is made of fibrous material.

[0042] To prevent dry burning due to insufficient atomizing fluid supply, the thermal conductivity of the area corresponding to the liquid guiding hole 13 of the heating element 2 is higher than that of the rest of the heating element 2. After each atomization cycle, the atomizing fluid needs to enter the area of ​​the liquid guiding fiber sheet 3 located within the fixed tube 1 through the liquid guiding hole 13 and the clamping port 123 to replenish the atomizing fluid. Since the area of ​​the liquid guiding fiber sheet 3 corresponding to the liquid guiding hole 13 receives atomizing fluid more quickly, by ensuring that the thermal conductivity of the area corresponding to the liquid guiding hole 13 of the heating element 2 is higher than that of the rest of the heating element 2, the problem of dry burning due to insufficient atomizing fluid supply is effectively avoided.

[0043] The porosity of the liquid-guiding fiber sheet 3 at the clamping opening 123 is lower than that of the rest of the liquid-guiding fiber sheet 3. Therefore, the strength and wear resistance of the liquid-guiding fiber sheet 3 at the clamping opening 123 are greater than those of the rest of the sheet. Consequently, it is less likely to warp due to friction during assembly, avoiding the problems of warping and excessive atomization liquid adsorption, leading to atomization liquid leakage, as seen in existing technologies. To further prevent leakage due to excessive atomization liquid adsorption, the capillary force at the lower end of the liquid-guiding fiber sheet 3 is greater than that at the upper end. In other words, the lower end of the liquid-guiding fiber sheet 3 has a stronger adsorption capacity, and the atomization liquid is less likely to flow downwards due to gravity.

[0044] In one embodiment, the clamping force of the lower end of the heating element 2 on the liquid-conducting fiber sheet 3 is greater than the clamping force of the upper end of the heating element 2 on the liquid-conducting fiber sheet 3, thus better preventing the atomized liquid from leaking from the lower end of the liquid-conducting fiber sheet 3. That is, the lower end of the liquid-conducting fiber sheet 3 is jointly clamped by the inner wall of the fixing tube 1 and the heating element 2 to prevent leakage of the atomized liquid. Preferably, the clamping force of the upper end of the heating element 2 on the liquid-conducting fiber sheet 3 is 0 Newtons, thus enabling it to adsorb a larger amount of atomized liquid.

[0045] The positioning post 4 is inserted at the second end of the fixing tube 1. The first end of the wire 5 is clamped between the positioning post 4 and the fixing tube 1 and connected to the heating element 2. The second end of the wire 5 extends outside the fixing tube 1. In this embodiment, a positioning groove 41 is provided on the outer circumferential surface of the positioning post 4. The positioning groove 41 extends along the length of the positioning post 4. The groove wall of the positioning groove 41 and the inner wall of the fixing tube 1 together clamp the wire 5, thus not only fixing the wire 5 well, but also preventing the wire 5 from being broken. Specifically, the two opposite ends of the heating element 2 are respectively connected to the wire 5, and are electrically connected to the power source through the wire 5 to obtain electrical energy.

[0046] In one embodiment, a reversible phase change gel is coated on the lower end face of the liquid-conducting fiber sheet 3 within the fixed tube 1. When the heating element 2 is not in operation, the reversible phase change gel is in a gel state, binding the liquid-conducting fiber sheet 3 and preventing it from excessively adsorbing the atomizing liquid, which would cause excessive expansion of the fiber sheet 3 and thus compress the heating element 2, potentially altering its resistance. When the heating element 2 is in operation, the reversible phase change gel becomes a sol state and flows into the positioning groove 41 under gravity. After cooling, the reversible phase change gel solidifies back into a gel state, sealing the gap between the wire 5 and the positioning groove 41. The reversible phase change gel may contain a hydrocarbon-aryl-glycosyl three-stage glycosyl gelling agent.

[0047] In one embodiment, the liquid-guiding fiber sheet 3 includes a first cotton sheet and a second cotton sheet. The first cotton sheet covers the heating element 2, and the second cotton sheet covers the first cotton sheet and covers the liquid-guiding hole 13. The porosity of the first cotton sheet in the region located within the fixed tube 1 is less than that of the second cotton sheet in the region located within the fixed tube 1, and the thickness of the second cotton sheet is greater than that of the first cotton sheet. Therefore, this structure effectively avoids the problem of excessive expansion of the liquid-guiding fiber sheet 3 after absorbing the atomized liquid, which could compress the heating element 2 and change its resistance. In addition, this structure provides smoother liquid supply and prevents the heating element 2 from burning dry.

[0048] The assembly process of this invention is as follows: First, the heating element 2 is welded to the wire 5. Then, the heating element 2 is wrapped around the mounting rod, and then a liquid-conducting fiber sheet 3 is wrapped around the heating element 2. Next, the liquid-conducting fiber sheet 3, which is wrapped around the mounting rod and the heating element 2, is inserted into the fixing tube 1 from the first end of the fixing tube 1. During insertion, the end of the liquid-conducting fiber sheet 3 protrudes from the notch 12 and is pushed from the first guide port 121 towards the clamping port 123. After being pushed into place, the positioning pin 4 is inserted into the fixing tube 1 from the second end of the fixing tube 1 to tighten and fix the wire 5. Finally, the mounting rod is removed.

[0049] Please see Figure 5 This invention also discloses an electronic atomizing device 200, including a housing 201 and an atomizing core 100. The housing 201 has a storage chamber 202 for storing atomized liquid, and the storage chamber 202 contains absorbent cotton 203 for adsorbing the atomized liquid. A fixing seat 204 is provided on the bottom wall of the storage chamber 202. The atomizing core 100 is located in the storage chamber 202 and is used to atomize the atomized liquid in the storage chamber 202. The fixing tube 1 of the atomizing core 100 is connected to the fixing seat 204. The atomizing core 100 is as described above. Since the atomizing core 100 of this electronic atomizing device 200 has the same structure as the atomizing core 100 described above, it also has the same technical effect. Its structure will not be described in detail here.

[0050] In summary, firstly, since the notch 12 includes a first guide port 121, a second guide port 122, and a clamping port 123, the first guide port 121 is connected to the first end face of the fixed tube 1, the first end of the second guide port 122 is connected to the first guide port 121, and the second end of the second guide port 122 is connected to the clamping port 123; the diameters of the first guide port 121 and the second guide port 122 gradually increase along the direction of the first end face of the fixed tube 1. Therefore, during assembly, the operator does not need to worry about misalignment; they can simply push the first and second ends of the liquid-guiding fiber sheet 3 from the first guide port 121 to the clamping port 123, avoiding the problem of the heating element 2 being squeezed, which would affect the resistance value of the heating element 2. Therefore, the aerosol tastes good when the user inhales it.

[0051] Secondly, by setting the second guide port 122, the length of the clamping port 123 is shortened, thus reducing the friction time between the notch 12 and the lower side of the liquid guiding fiber sheet 3 during the assembly process. This avoids the problem of the liquid guiding fiber sheet 3 lifting up due to long friction time, which would create a gap between the liquid guiding fiber sheet 3 and the fixed tube 1, resulting in poor sealing and leakage.

[0052] Finally, since the porosity of the fluid-conducting fiber sheet 3 at the clamping port 123 is less than that of the rest of the fluid-conducting fiber sheet 3, the strength and wear resistance of this area are increased, the sealing performance is greatly improved, and the risk of oversaturation of the area of ​​the fluid-conducting fiber sheet 3 located in the fixed tube 1 is reduced.

[0053] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0054] The present invention has been described above with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other situations without modification, are all within the protection scope of the present invention.
