Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an atomizing core, an atomizer, and an atomizing device. Background Technology

[0002] The atomizing core in an atomizing device is usually a fiber sheet obtained from plant fibers through a hydroentangling process, such as a non-woven fabric sheet processed from non-woven fabric. Then, the fiber strips are cut into small sizes, multiple fiber strips are stacked, wrapped around the heating wire of the atomizing core, and then assembled.

[0003] However, the processing technology of fiber sheets can lead to uneven thickness distribution at different locations. This results in poor thickness consistency after multiple fiber strips are stacked, and the fibers will squeeze each other, causing the gaps between the fiber strips to be blocked, which can easily lead to clogging and oil leakage in the atomizing device. Utility Model Content

[0004] This application provides an atomizing core, an atomizer, and an atomizing device to solve the problem of easy core clogging and oil leakage caused by poor thickness uniformity of the fiber strip stacking of the atomizing core and blockage of the gaps between the fiber strips.

[0005] In one embodiment, an atomizing device is provided, including a heating element and a liquid guiding element that wraps around the heating element, the liquid guiding element being formed by winding a cord.

[0006] In one embodiment, the number of layers of the cord wound radially around the heating element is between 2 and 8.

[0007] In one embodiment, the winding method of the rope includes at least one of the following: spiral winding and cross winding.

[0008] In one embodiment, the radial width of the fluid guiding element is set between 1 mm and 10 mm.

[0009] In one embodiment, the cross-sectional shape of the cord includes a circle and a square.

[0010] In one embodiment, the material used to make the cord includes plant fibers.

[0011] In one embodiment, the atomizing core further includes a support element, which is sleeved on the outer periphery of the liquid guiding element; the support element has a liquid guiding hole to guide the atomizing matrix located on the outside of the support element into the liquid guiding element.

[0012] In one embodiment, the support element and the fluid guiding element are interference-fitted.

[0013] In one embodiment, an atomizer is provided, comprising: an atomizing core as described in any of the above embodiments.

[0014] In one embodiment, an atomizing device is provided, comprising: a power supply component and an atomizer as described in the above embodiments, wherein the power supply component is electrically connected to the atomizer to supply power to the atomizer.

[0015] According to the atomizing core of the above embodiment, a liquid-conducting element can be formed by winding thread to enclose the heating element. Because the thread is regularly shaped, small and stable gaps are formed between the layers of winding thread, creating a capillary structure that combines oil-locking and ventilation functions. This achieves the effects of improving oil leakage and preventing core clogging. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0028] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0029] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0030] Existing atomizer cores suffer from poor thickness uniformity in the internal fiber stacking, and the gaps between the fiber strips are blocked, leading to problems such as burnt cores and leakage.

[0031] In this application, a liquid-conducting element 2 can be formed by winding a rope 21 to wrap around the heating element 1. Because the rope 21 is regular in shape, small and stable gaps are formed between the layers of winding rope 21, which can form a capillary structure, taking into account both oil locking and ventilation functions, thereby achieving the effects of improving oil leakage and preventing core clogging.

[0032] Please refer to Figures 1 to 5 In one embodiment, an atomizing core is provided, which mainly includes a heating element 1 and a liquid guiding element 2. The liquid guiding element 2 is sleeved on the central body 7 and wraps around the heating element 1, wherein the liquid guiding element 2 is obtained by winding a rope 21.

[0033] During the winding process of the cord 21, the central body 7 serves as a fixture for fixing the heating element 1 and the liquid guiding element 2, providing structural support for them. The heating element 1 can be mesh-like, filament-like, or similar shapes. When the heating element 1 operates, it generates heat, heating the atomizing matrix in contact with it to its boiling point, thus atomizing it. The atomizing matrix may include substances such as propylene glycol and fragrances, and the aerosol produced after atomization can be inhaled by the user.

[0034] Reference Figure 2 or Figure 5 As shown, the heating element 1 is mounted on the outer surface of the central body 7. For example, when the heating element 1 has a mesh structure, it can be sleeved on the central body 7 and form an interference fit, thereby allowing the central body 7 to define the position of the heating element 1. In another example, when the heating element 1 has a filament structure, it can be wound around the central body 7, thereby allowing the pressure force between the heating element 1 and the central body 7 to define the position of the heating element 1 on the central body 7.

[0035] The liquid guiding element 2 encapsulates the heating element 1. On one hand, the liquid guiding element 2 guides the atomizing matrix to the heating element 1, facilitating atomization of the matrix during the heating process of the heating element 1. On the other hand, the liquid guiding element 2 also allows the atomized gas to exit outside the liquid guiding element 2. The liquid guiding element 2 is obtained by winding multiple layers of cord 21 around the central body 7. Due to the regular shape of the cord 21, small and stable gaps are formed between the layers of cord 21, creating a capillary structure. A capillary structure refers to a structure with small channels or pores that can produce a capillary effect.

[0036] When the liquid guiding element 2 comes into contact with the atomizing matrix, the atomizing matrix rises along the gaps in the liquid guiding element 2 under the capillary effect, filling the liquid guiding element 2 with the atomizing matrix. This allows the atomizing matrix to be transferred to the vicinity of the heating element 1 through the liquid guiding element 2. Therefore, the liquid guiding element 2 can simultaneously lock in oil and facilitate ventilation, preventing situations where some areas of the liquid guiding element 2 have excessively large gaps that could lead to oil leakage, or areas with excessively small gaps that would hinder the passage of atomized aerosols and cause wicking. This achieves the effects of improving oil leakage and preventing wicking.

[0037] In one embodiment, the number of layers of the cord 21 wound radially around the heating element 1 is between 2 and 8.

[0038] The number of layers of the cord 21 wound radially around the heating element 1 can also be understood as the cumulative number of layers of the cord 21 stacked radially around the heating element 1. For example, the number of layers of the cord 21 wound radially around the heating element 1 can be 2, 4, 5, or 8 layers, etc., without further limitation. If the number of winding layers is too small, the number of gaps formed in the liquid guiding element 2 will be too small, which will easily lead to oil leakage. If the number of winding layers is too large, the amount of atomizing matrix that can be stored in the liquid guiding element 2 will be too large. This will cause the atomizing matrix to accumulate around the heating element 1, which will easily lead to insufficient atomization. Therefore, the radial width of the liquid guiding element 2 is within the above-mentioned range, which can improve the oil-locking effect and ensure that the atomizing matrix located in the liquid guiding element 2 is fully atomized when the heating element 1 is working.

[0039] In one embodiment, the winding method of the cord 21 includes at least one of the following: spiral winding and cross winding.

[0040] Spiral winding refers to the rope 21 being wound around the object in a spiral shape, with each turn having a certain angle and spacing from the previous turn, resembling a spiral line. Cross winding refers to the rope 21 crossing over each other during the winding process, forming a mesh-like or grid-like structure. In one example, the rope 21 can be formed by spiral winding to create the liquid-guiding element 2. In one or more examples, the rope 21 can also be wound by cross winding. Alternatively, the rope 21 can be formed by a combination of spiral winding and cross winding to create the liquid-guiding element 2, for example, spiral winding first, followed by cross winding, or vice versa. This can improve the uniformity of the gap distribution in the liquid-guiding element 2.

[0041] In one embodiment, reference is made to Figure 2 As shown, the radial width of the liquid guiding element 2 is set between 1 mm and 10 mm.

[0042] The radial width W of the liquid guiding element 2 can be set between 1 mm and 10 mm. For example, the radial width of the liquid guiding element 2 can be selected as 1 mm, 5 mm, 8 mm, and 10 mm, etc., without further limitation. If the radial width of the liquid guiding element 2 is too small, the oil-locking effect will be reduced. If the radial width of the liquid guiding element 2 is too large, too much atomizing matrix will accumulate around the heating element 1, easily causing insufficient atomization. Therefore, the radial width of the liquid guiding element 2 within the above-mentioned range can improve the oil-locking effect and ensure that the atomizing matrix located in the liquid guiding element 2 is fully atomized when the heating element 1 is working.

[0043] In one embodiment, reference is made to Figure 3 As shown, the cross-sectional shape of the cord 21 may include a circle. A circle is a regular and symmetrical shape, and when the cords 21 are intertwined, adjacent cords 21 will form uniform arc-shaped gaps. Especially when cords 21 of the same diameter are tightly intertwined, the size of the gaps at different positions has a high degree of consistency.

[0044] In one or more embodiments, the cross-sectional shape of the cord 21 may also include a square shape. A square is a regular and symmetrical shape. When the cords 21 are intertwined, for example, when square cords 21 are intertwined side by side in the same layer, or when two adjacent layers are intertwined, it can ensure that the gaps between cords 21 in adjacent positions are uniform and improve the consistency of the gap distribution.

[0045] In the liquid-conducting element 2 formed by multi-layer winding, the mutual compression and orderly arrangement of the cords 21 can promote the uniform distribution of gaps. Furthermore, the cords 21 also possess a certain degree of elasticity, ensuring that no part of the cords is too loose or too tight during winding, thereby further maintaining the uniformity of the gap size and improving the effects of reducing oil leakage and preventing core clogging.

[0046] In one embodiment, the liquid guiding element 2 can be obtained by winding a single thread 21 multiple times on the outer surface of the central body 7. In one or more embodiments, the liquid guiding element 2 can be obtained by winding at least two threads 21 multiple times in an orderly manner on the outer surface of the central body 7. When the number of threads 21 is at least two, the diameter of the at least two threads 21 remains the same. The liquid guiding element 2 formed by winding threads 21 with the same diameter can ensure the uniformity of the void size in the liquid guiding element 2.

[0047] In one embodiment, the material used to make the cord 21 includes plant fibers. Plant fibers refer to a type of tissue component that is widely found in plants and has a supporting and protective function. For example, the plant fibers may include cotton fibers and hemp fibers. The cord 21 made of the plant fibers has advantages such as good water absorption, water retention, and chemical stability. The liquid guiding element 2 can quickly absorb the atomizing matrix and evenly transfer the atomizing matrix to the heating element 1. Furthermore, the plant fibers are chemically stable and will not react chemically with the atomizing matrix, thus not affecting the taste of the atomized aerosol.

[0048] In some embodiments, the cord 21 can be obtained by processing plant fibers using a spinning process. During spinning, the plant fibers are stretched and rotated, allowing them to interweave and form a continuous cord 21. For example, when cotton fibers are used, cotton yarn can be obtained, and the processed cord 21 has a high uniformity in diameter. This can further improve the uniformity of the void size in the liquid guiding element 2.

[0049] In one embodiment, reference is made to Figure 4 and Figure 5 As shown, the atomizing core also includes a support element 3, which is sleeved on the outer periphery of the liquid guiding element 2. The support element 3 is sleeved on the outer surface of the liquid guiding element 2 (the surface of the liquid guiding element 2 away from the heating element 1), which can limit the radial position of the liquid guiding element 2 and prevent the cord 21 from loosening after being wrapped layer by layer, thereby reducing the uniformity of the distribution of the void size in the liquid guiding element 2.

[0050] In one embodiment, reference is made to Figure 4 and Figure 5 As shown, the support element 3 has a liquid guiding hole 301 to guide the atomizing matrix located outside the support element 3 into the liquid guiding element 2. The liquid guiding hole 301 connects the space outside the support element 3 and the space inside the support element 3. Multiple liquid guiding holes 301 can be provided. In one or more embodiments, the multiple liquid guiding holes 301 can be distributed at intervals along the length direction of the support element 3. And / or, the multiple liquid guiding holes 301 can be distributed around the center of the support element 3 at intervals of a certain angle. The cross-sectional shape of the liquid guiding hole 301 can be circular, rectangular, or other shapes. Those skilled in the art can determine the cross-sectional shape of the liquid guiding hole 301 according to specific design requirements, and no further limitations are made here. The liquid guiding element 2 blocks one end of the liquid guiding hole 301 located inside the support element 3, allowing the atomizing matrix located outside the support element 3 to enter the liquid guiding element 2 through the liquid guiding hole 301, and then be guided to the heating element 1 through the liquid guiding element 2.

[0051] In one embodiment, the support element 3 and the liquid guiding element 2 are interference-fitted. An interference fit refers to the way the two elements are tightly connected after elastic deformation during assembly. The interference fit between the support element 3 and the liquid guiding element 2 improves the radial structural stability of the liquid guiding element 2, preventing the fiber ropes within it from unraveling. Furthermore, the support element 3 also protects the liquid guiding element 2 and the heating element 1 located within it, preventing deformation or damage caused by external forces, collisions, or other environmental factors.

[0052] In one embodiment, the support element 3 is made of a metal material. The support element 3, made of a metal material, has high structural strength, which improves the protection of the liquid-conducting element 2 and the heating element 1. Furthermore, the support element 3 made of a metal material has good thermal conductivity. In one or more embodiments, when the heating element 1 is in operation, the heat generated by the heating element 1 can be transferred to the atomizing matrix in the area surrounding the support element 3, allowing the atomizing matrix to be uniformly heated and atomized. In another example, when the heating element 1 is not in operation, the support element 3 made of a metal material can also assist the heating element 1 in heat dissipation, improving the cooling efficiency of the heating core and reducing the probability of the heating core clogging.

[0053] In one or more embodiments, the support element 3 can be made of stainless steel, a type of metal. Stainless steel has good chemical stability, will not react chemically with the atomizing matrix, will not affect the taste of the atomized aerosol, and will not corrode the heating core under long-term use, thereby improving the service life of the support element 3.

[0054] In one or more embodiments, the support element 3 may be made of titanium or nickel, both of which are metallic materials. Titanium and nickel have good chemical stability, will not react chemically with the atomizing matrix, will not affect the taste of the atomized aerosol, and will not corrode the heating core under long-term use, thereby improving the service life of the support element 3.

[0055] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, the central body 7 has a circular cross-sectional shape. The circular cross-sectional shape of the central body 7 ensures the roundness of the heating element 1 on its outer surface and improves the uniformity of the thickness of the liquid guiding element 2 distributed radially.

[0056] In one or more embodiments, the central body 7 may include a cotton swab; or, the central body 7 may include a metal rod, thereby facilitating the assembly and positioning of the heating element.

[0057] Reference Figure 6 As shown, in one embodiment, an atomizer is provided, the atomizer comprising an atomizing core as described in any of the above embodiments.

[0058] In this embodiment of the application, the atomizer atomizes the atomizing matrix into an aerosol through the atomizing core.

[0059] Reference Figure 7 , Figure 8 as well as Figure 9 As shown, in one embodiment, an electronic atomizing device is provided, the atomizing device including a power supply component 5 and an atomizer as described in the above embodiment, the power supply component 5 being electrically connected to the atomizer to supply power to the atomizer.

[0060] In this embodiment, the power supply component 5 provides electrical energy to the atomizer, which heats the atomizing matrix into an aerosol. The electronic atomizing device may further include a housing 4 and a base 6 connected to and cooperating with the housing 4. The housing 4 has an accommodating cavity for mounting the atomizer and the power supply component 5. The base 6 is used to seal the accommodating cavity. In some examples, the housing 4, through its spatial cooperation with the atomizer, forms a liquid storage chamber for storing the atomizing matrix.

[0061] The atomizing device can be a disposable product or a refillable atomizing device. For disposable atomizing devices, the atomizer and power supply component 5 are fixedly connected. For refillable atomizing devices, the atomizer and power supply component 5 are detachably connected, and the atomizer and power supply component 5 can be replaced as needed.

[0062] In summary, this application discloses an atomizing core, an atomizer, and an electronic atomizing device. This application uses a cord 21 wound around to form a liquid-guiding element 2 that wraps around the heating element 1. Because the cord 21 is regularly wound, small and stable gaps are formed between the layers of cord 21, creating a capillary structure that balances oil retention and ventilation, thereby improving oil leakage and preventing core clogging.
