Abstract
Description
Technical Field
[0001] The present application relates to the field of atomization devices, and particularly to an atomization core and an atomization device. Background Art
[0002] Atomization devices have been widely used in fields such as electronic cigarettes and the medical field. Taking electronic cigarettes as an example, as a substitute for tobacco, they have gradually become popular among smokers. Generally, an electronic cigarette has a cartridge and an atomization core. When the e-liquid in the cartridge passes through the atomization core, it is heated to form an aerosol for the user to inhale. The atomization efficiency of the atomization device is a major factor affecting the user experience.
[0003] The atomization efficiency of the atomization device is generally affected by the temperature distribution characteristics of the heating surface of the atomization core. Currently, whether it is a cotton core, a mesh core or a ceramic core, the filamentous porous material characteristics will cause the atomization liquid to be filtered when flowing through, resulting in a change in the composition of the atomization liquid; and due to uneven temperature distribution during heating, the size of the aerosol particles generated will be uncontrollable.
[0004] In addition, the atomization efficiency and effect of the atomization device are also affected by the flow rate of the atomization liquid. If the atomization liquid is supplied too fast, a process of boiling the oil will occur and spitting will appear, affecting the atomization effect; if the atomization liquid is supplied slowly, the temperature of the atomization core will be too high, causing the atomization core to dry burn. Summary of the Invention
[0005] The purpose of the present application is to provide an atomization core and an atomization device, which can control the supply speed of the atomization liquid by changing the structure of the atomization core, thereby stabilizing the atomization efficiency and effect and improving the user experience.
[0006] To solve the above technical problems, a solution proposed in the present application is:
[0007] An atomization core, comprising: a housing having an inlet, an outlet and an accommodation space; a capillary bundle including a plurality of capillary ducts with hollow interiors and arranged closely to each other, the capillary bundle is disposed in the accommodation space, its first end is communicated with the inlet, and the second end is communicated with the outlet; and a heating element disposed at the outlet and connected to the second end of the capillary bundle, the heating element is used to heat and atomize the atomization liquid flowing out of the capillary bundle after being energized; wherein, there is a gap between adjacent two of the capillary ducts, and the gap is used to store the atomization liquid and allow the atomization liquid to pass through.

[0013] In an embodiment of the present application, the orifices of the heating element and the orifices of the capillary duct are at least partially staggered.
[0014] In an embodiment of the present application, the heating foil is provided in a multi-grooved shape, and the groove length of the heating foil is generally greater than the wall thickness of the capillary duct.
[0015] In an embodiment of the present application, the heating film is provided in a porous shape, and the inner diameter of the holes of the heating film is greater than the wall thickness of the capillary duct.
[0016] In an embodiment of the present application, there is also at least one heat conduction tube, which is arranged adjacent to the capillary duct, and the heat conduction tube is used to heat the atomized liquid around it to increase the flow rate of the atomized liquid reaching the heating element.
[0017] In an embodiment of the present application, one end of the heat conduction tube is connected to the heating element to conduct heat to the liquid in the remaining part of the heat conduction tube, namely the oil storage chamber, so as to accelerate the liquid flow.
[0018] To solve the above technical problems, another solution proposed by the present application is:
[0019] An atomizing device, comprising: a housing, a mouthpiece provided at one end of the housing for a user to inhale an aerosol fluid; an oil storage chamber provided in the housing for storing an atomized liquid; and an atomizing core provided in the housing and located between the oil storage chamber and the mouthpiece; the inlet of the atomizing core is communicated with the oil storage chamber through an oil delivery channel, and the outlet of the atomizing core is communicated with the mouthpiece through an air outlet channel for heating and atomizing the atomized liquid to form the aerosol fluid; wherein, the atomizing core is the atomizing core as described above.
[0020] The beneficial effects of the present application are as follows: Different from the prior art, the present application proposes an atomization core and an atomization device. The atomization core uses a capillary bundle array composed of multiple mutually closely arranged capillary ducts to transfer the atomization liquid, and can achieve cottonless atomization by controlling the length of the capillary ducts to eliminate the use of porous materials, thereby avoiding the filtering effect caused by cotton or porous materials.

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0033] Please refer to Figure 1 and Figure 2 , Figure 1 FIG. is a schematic structural diagram of the atomization core 100 in the present application in one direction, Figure 2 FIG. is Figure 1 a schematic cross-sectional view in. In the present application, the atomization core 100 may include a housing 110, a capillary bundle 120, and a heating element 150. The housing 110 has an inlet 111 and an outlet 112. The inlet 111 is used for introducing atomization liquid, and the outlet 112 is used for discharging aerosol fluid. The housing 110 has an accommodation space inside. The capillary bundle 120 is disposed in the housing 110 and includes a plurality of capillary ducts 124 that are internally hollow and closely arranged. The first end of the capillary bundle 120 is communicated with the inlet 111 of the housing 110, and the second end of the capillary bundle 120 is communicated with the outlet 112. The plurality of capillary ducts 124 in the capillary bundle 120 transmit the atomization liquid by means of capillary action through their own smaller apertures (less than 150 μm). The heating element 150 is disposed near the outlet 112 and is connected to the second end of the capillary bundle 120. The atomization liquid transmitted through the capillary bundle 120 will be heated and atomized after encountering the energized heating element 150 to form aerosol fluid, and finally discharged from the outlet 112 (refer to the dashed arrow in Figure 2 ).
[0034] Specifically, each capillary duct 124 includes a tube wall 121 and a tube hole 122. The material of the tube wall 121 may be a glass material such as quartz glass, borosilicate glass, or aluminosilicate glass, or a heat-resistant polymer material such as aromatic ring polymer, heterocyclic polymer, ladder polymer, or organoelement polymer, or an inorganic compound. It can be understood that those skilled in the art can select appropriate materials to process and form the capillary bundle according to the actual situation, which will not be elaborated here one by one.
[0035] Among them, adjacent capillary ducts 124 are mutually attached through the tube walls 121 to form a closed gap 140, so as to allow the atomization liquid to be stored in or pass through the gap 140, so that the atomization core 100 can pass a certain amount of atomization liquid during the atomization process. Moreover, the gap 140 can form a conveying channel similar to the control tube 122 in the capillary bundle 120, and can also play a role in conveying the atomization liquid.
[0036] Understandably, in order to maintain good capillary action, the inner diameter range of each capillary duct 122 should be less than 150 μm, and the maximum width of the cross-section of the gap 140 should be less than 100 μm. In one embodiment, the inner diameter of the capillary duct 122 is in the range of 5 μm to 100 μm, and the maximum width of the cross-section of the gap 140 is 80 μm; in another embodiment, the inner diameter of the capillary duct 122 is in the range of 10 μm to 40 μm, and the maximum width of the cross-section of the gap 140 is 50 μm. In addition, the wall thickness range of the tube wall 121 of the capillary duct 124 is in the range of 5 μm to 80 μm.
[0037] In the above embodiment, the atomization core 100 forms a capillary bundle 120 by using an array of capillary ducts 124, and transmits the atomization liquid by means of the hollow feature of the capillary duct 124 itself, so that the atomization core can achieve cotton-free atomization, further avoiding the filtration effect caused by cotton or porous ceramics, and can achieve isometric atomization or ensure the consistency of the aerosol chemical composition and the atomization liquid composition.
[0038] Furthermore, the arrangement of the capillary bundle 120 can be various. Combining Figure 2 and referring to Figure 4 , multiple closely arranged capillary ducts 124 form a regular quadrilateral array. Since the capillary duct 124 is circular, the cross-sectional shape of the 140 gap includes four spliced 1 / 4 arc segments. Referring to Figure 7 , in the array forming a regular triangle, since the capillary duct 224 is circular, the cross-sectional shape of the gap 240 includes three spliced 1 / 3 arc segments.
[0039] In other embodiments, the cross-section of each capillary duct in the capillary bundle 420 can be a regular polygon. Combining Figure 8 , multiple closely arranged capillary ducts 420 form a regular triangle array. Since the capillary duct 430 is a regular hexagon, the cross-sectional shape of the 440 gap includes three spliced straight segments. Combining Figure 9 , multiple closely arranged capillary ducts 420 form a regular quadrilateral array. Since the capillary duct 430 is a regular octagon, the cross-sectional shape of the 440 gap includes four spliced straight segments. In addition, those skilled in the art can indirectly control the length of the gap 140 / 240 by controlling the length of the capillary bundle 120 / 240, so that the oil locking ability of the atomization core 100 can be adjusted, and at the same time, the atomization dose can also be adjusted.
[0040] For high-viscosity atomization liquids, such as the usage scenarios of THC (tetrahydrocannabinol) or CBD (cannabidiol) series, most of the power of traditional ceramic atomizer cores is used to heat the atomization liquid to ensure its flow. While other atomizer cores improve the atomization efficiency, the flow of the atomization liquid becomes another shortcoming. Based on this, continue to refer to Figure 1 , the atomizer core 100 may further include a heat conduction tube 130. The heat conduction tube 130 is arranged adjacent to the capillary bundle 120 and can heat the atomization liquid around it and the atomization liquid in the oil chamber by heating itself or conducting heat, so as to improve the fluidity of the atomization liquid with a relatively high viscosity by raising the temperature and reduce the influence of different types of atomization liquids on the atomization effect; moreover, it has an improvement effect on the freezing and increased viscosity of the atomization liquid in a low-temperature usage environment.
[0041] Specifically, the heat conduction tube 130 can be arranged in the capillary bundle 120 formed by a plurality of capillary ducts 124, and the extending direction is the same as that of the capillary ducts 124. In this way, the heat conduction tube 130 is actually surrounded by a plurality of capillary ducts 124. The capillary bundles 120 with different array patterns surround the heat conduction tube 130 in different ways.
[0042] Combined with Figure 4 , Figure 4 is an arrangement method in which the capillary bundle 120 surrounds the heat conduction tube 130. A plurality of capillary bundles 120 are arranged in a regular quadrilateral array to form a 3*3 square array. Among them, eight capillary bundles 120 surround one heat conduction tube 130.
[0043] Combined with Figure 5 and Figure 7 , Figure 5 is another arrangement method of the capillary bundle 220 array in the atomizer core 200 in the present application. Figure 7 is Figure 5 The local array schematic diagram in. Among them, a plurality of capillary bundles 220 are closely arranged in a regular hexagon in the housing 210 to form a 2*2* hexagonal array. Among them, six capillary bundles 220 surround one heat conduction tube 230.
[0044] When the heat conduction tube 130 generates heat or transfers heat, it will preheat the surrounding capillary bundle 120, the atomization liquid in the capillary bundle 120, and the atomization liquid in the oil chamber. Such a setting can ensure that the heat conduction tube 130 is not located in the edge area close to the housing 110, avoid heat waste, and improve the heating effect; moreover, it can also avoid the situation where there are multiple heat conduction tubes 130 in the same 3*3 array or a 2*2* array, resulting in too high a preheating temperature of the atomization liquid.
[0045] Of course, in other embodiments, those skilled in the art can also adjust the number of capillary bundles 120 surrounding the heat pipe 130 according to the array mode of the capillary bundles 120. For example, in one embodiment, in combination with Figure 8 , for a regular triangular array, one of the three is the heat pipe 330, and the other two are capillary ducts 320; for example, in one embodiment, in combination with Figure 9 , for a regular quadrilateral array, one of the four is the heat pipe 330, and the remaining three are capillary ducts 320.
[0046] The above arrangements are merely examples for illustration. It can be understood that those skilled in the art can select the number and arrangement mode of the heat pipes 130 according to the actual situation, which will not be elaborated one by one here.
[0047] In combination with Figure 2 and referring to Figure 10 5, in the present application, the heating element 150 is in the shape of a foil made of a metal material. The material can be a heat-conducting thin sheet of a single element such as gold, silver, or titanium, or any biocompatible metal or alloy or compound. After being energized, its own temperature will rise, causing the atomized liquid to be heated and atomized. Among them, in order to improve the atomization uniformity, a porous array 152 can be provided on the surface of the base material 151 of the heating element 150. The porous array 152 can improve the diffusion distribution of the atomized liquid on the metal foil, thereby facilitating uniform atomization. In other embodiments, the porous array 152 with a circular cross-section on the surface of the heating element 150 can also be replaced with a slot array with a rectangular cross-section. Those skilled in the art can select according to the actual situation, which will not be elaborated one by one here.
[0048] Specifically, taking the porous array 152 with a circular cross-section as an example. The pore diameter of the porous array 152 can be smaller than the pore diameter of the capillary bundle 120, but generally not smaller than the wall thickness of the capillary. This can enable the atomized liquid to be rapidly penetrated and diffused by the porous array 152 when it reaches the surface of the heating element 150, increasing the heating area of the atomized liquid, thereby increasing the atomization speed of the atomized liquid.
[0049] In addition, in combination with Figure 3 , in some embodiments, the end face of the capillary bundle 120 connected to the heating element 150 can be a concave surface, and the shape of the corresponding heating element 150 is also set to the corresponding concave surface. This setting mode can make the temperature of the entire atomization surface more uniform compared to the capillary bundle with a flat surface, and further can control the process of aerosol nucleation. Especially when the atomization surface faces atomization, after the atomization core 100 stops working, the aerosol fluid re-liquefies. The concave surface can well confine the re-liquefied atomized liquid, causing it to flow back into the atomization core again, avoiding spreading to other areas.
[0050] Furthermore, at least a part of the openings in the porous array 152 is arranged offset from the orifices of the capillary tube bundles 120. In this way, the substrate portion can partially cover the orifices of the capillary tube bundles 120, playing a buffering role for the atomized liquid and avoiding the phenomenon of liquid leakage due to too fast flow rate of the atomized liquid.
[0051] Continuing to refer to Figure 2 , in an embodiment of the present application, the first ends of the capillary tube bundle arrays 120 are received inside the inlet 111 of the housing 110, so that a liquid guiding channel 113 is formed at the position of the inlet 111 of the housing 110. The liquid guiding channel 113 can also store a certain amount of atomized liquid to ensure sufficient supply of the atomized liquid in the capillary tube bundle arrays 120.
[0052] It can be understood that, in order to realize preheating of the atomized liquid, at least part of the heat conduction tubes 130 can also be arranged in the liquid guiding channel 113 and adjacent to the first ends of the capillary tube bundle arrays 120. Please refer to FIG. Figure 6 , Figure 6 is a schematic structural diagram of another embodiment of the atomizing core in the present application. Among them, one end of the heat conduction tube 230 is connected to the heating element 250, and the other end extends into the liquid guiding channel 213.
[0053] In an embodiment, the heat conduction tube 230 has a heating resistance wire inside, or the resistance of the heat conduction tube itself can also be used for heating, and it can actively generate heat after being energized. The triggering timing and working duration of the active heating can be controlled by a program, and it can be instantaneously energized for heating when heating is required (for example, when the user sucks).
[0054] In another embodiment, the heat conduction tube 230 has a heat conduction region made of a heat conduction material inside. After the heating element 250 finishes heating and atomizing, the remaining heat on the atomizing core is quickly transferred from one end of the heat conduction tube 230 to the other end, thereby heating the atomized liquid in the oil tank. In this way, the heat of the heating element 250 can be instantaneously introduced into the oil tank, reducing the temperature of the atomizing core, thereby reducing the amount of aerosol generated due to inertia after the suction stops, greatly reducing the generation of condensate, and at the same time increasing the flow rate of the atomized liquid refilling.
[0055] In addition, the material of the heat conduction region of the heat conduction tube 230 can be a material with better heat conduction efficiency such as heat conduction silica gel, aluminum, titanium, silver, stainless steel, etc., and the structure of the heat conduction tube 230 itself can also be hollow or porous, which is convenient for heat conduction with the atomized liquid. It can be understood that those skilled in the art can select and adjust according to the actual situation, and will not be elaborated one by one here.
[0056] In addition, in another embodiment, the heat conduction tube 130 can be completely located in the liquid guide channel 213. The length extension direction thereof is perpendicular to the extension direction of the capillary bundle 220, so that the heat conduction tube 130 can heat only the inside of the liquid guide channel 113 by means of the heating unit it has, without heating through the side wall of the capillary bundle 120 by means of solid heat transfer, and the preheating effect is better.
[0057] The atomization core 100 in the present application can be used in all heating atomization application scenarios, such as electronic cigarettes, CBD or THC or Delta series atomization, medical atomization, and herbal atomization, etc. Only the atomization liquid in the above embodiments needs to be replaced. It should be understood that the atomization core 100 in the present application has no limitation on different atomization liquids.
[0058] The following takes the application of the atomization core 100 to an atomization device such as an electronic cigarette as an example for illustration. Refer to Figure 11 , the electronic cigarette 300 in the present application can include components such as a housing, an oil tank 310, an atomization core 350, and a mouthpiece 320. The housing serves as a protective shell of the electronic cigarette 300 and can be grasped by the user when in use. An accommodation space is provided inside the housing, and devices such as the oil tank 310 and the atomization core 350 can be arranged in this accommodation space. The oil tank 310 is communicated with the inlet 111 of the atomization core through an oil delivery channel 330, and the mouthpiece 320 is communicated with the outlet 112 of the atomization core through an air outlet channel 360. The mouthpiece 320 is arranged at one end of the housing. When the user holds the housing and performs a sucking action, the atomization liquid in the oil tank 310 is conveyed into the atomization core and is heated and atomized to form an aerosol fluid, and finally is transmitted to the user's lungs through the mouthpiece 320 along with the user's sucking.
[0059] The specific structural features of the atomization core in this embodiment can refer to the above embodiments and will not be elaborated here one by one. This embodiment only exemplarily shows the relevant module structural features that can solve the technical problems of the present application. The remaining components of the electronic cigarette 300 are not drawn, but should not be understood as missing or non-existent.
[0060] In summary, the present application provides an atomizing core and an atomizing device. By changing the structure for transporting the atomizing liquid, the atomizing core stores and transports the atomizing liquid through capillary bundles and the gaps therein, enabling the atomizing core to achieve cotton-free atomization. Further, it avoids the filtering effect caused by cotton or porous ceramics, and can achieve isometric atomization or ensure the consistency between the chemical composition of the aerosol and that of the atomizing liquid. Further, by arranging a heat conduction tube inside the atomizing core of the present application, the atomizing liquid can be preheated in advance or the residual heat after the atomizing core stops sucking can be utilized to improve the flow of the atomizing liquid in the oil tank, thereby improving the stability of the atomizing efficiency of the atomizing liquid and avoiding the influence of room temperature and the viscosity characteristics of different types of atomizing liquids on the atomizing effect. Further, by responding to different operations of the user, the atomizing device improves the flow of the atomizing liquid, enabling the atomizing action of the atomizing core to match the sucking action of the user and enhancing the user experience. In addition, by arranging a first valve in the atomizing core of the present application, the disordered liquid flow caused by the air pressure in the oil tank can be prevented, thereby ensuring the consistency of the dosage for each atomization, namely the so-called dosage-controlled atomization.
[0061] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
