Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aerosols, in particular to an atomizing core and an atomizing device. Background Art
[0002] Aerosol refers to a colloidal dispersion system composed of solid or liquid particles suspended in a gas medium. Since aerosol can be absorbed by the human body through the respiratory system, the aerosol matrix is heated and atomized with the help of an atomizing device to generate aerosol. It is widely used in medical devices, consumer electronics and other fields.
[0003] Traditional atomizers typically use a liquid-carrying sponge or similar device to attract and store the aerosol matrix through capillary action. A heating element within the sponge then heats the aerosol matrix within the atomized sponge to generate a usable aerosol. However, factors such as pressure imbalances inside and outside the sponge can prevent the sponge from stably attracting the aerosol matrix, leading to unstable aerosol production and even dry burning.

This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.
[0033] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.
[0034] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).
[0035] The terms "axial", "radial" and "circumferential" used in this article are three different directions defined based on the overall structural profile of the atomizer core; among them, "axial" can be understood as the length direction of the atomizer core or the direction of the axis; accordingly, "radial" refers to the direction perpendicular to the "axial" direction, and "circumferential" refers to the direction around the "axial" direction.
[0036] See also Figures 1 to 5 The embodiment of the present application provides an atomizer core that can be installed and applied to an atomizer device. By heating the aerosol matrix, the atomizer device can output a usable aerosol; the atomizer core includes a bracket component 10, a liquid guide component 20, a heating component 30, and other functional components that exist as needed, which are described in detail below.
[0037] See also Figures 1 to 3The bracket member 10 is roughly a tubular structure made of heat-insulating material and having a preset length in the axial direction. For the convenience of distinction and description, the tube body space of the bracket member 10 is defined as the assembly channel 10a, that is, the assembly channel 10a is set to pass through the bracket member 10 along the axial direction; the liquid inlet channel 10b that connects the assembly channel 10a with the outside of the bracket member 10 is provided on the side wall of the bracket member 10 in the circumferential direction or radial direction, that is, the liquid inlet channel 10b is equivalent to being set to pass through the side wall of the bracket member 10 in the radial direction.
[0038] In some embodiments, the bracket member 10 can be assembled inside the atomization device so that the two ends of the bracket member 10 (i.e., the axial ends of the assembly channel 10a) are respectively connected to the air inlet channel and the air outlet channel of the atomization device; and the liquid inlet channel 10b is connected to the liquid storage chamber provided inside the atomization device and used to store the aerosol matrix, so as to provide structural support for the aerosol matrix to enter the bracket member 10 or the interior of the atomization core with the help of the liquid inlet channel 10b.
[0039] See also Figures 1 to 4 The liquid guiding member 20 can be a structure made of microporous ceramic material, or a structure made of cotton fiber materials such as seaweed cotton, linen cotton, and absorbent cotton; the liquid guiding member 20 is inserted and fixed in the assembly channel 10a in the form of a cover for the liquid inlet channel 10b, so as to attract and store the aerosol matrix entering through the liquid inlet channel 10b with the help of the liquid guiding member 20.
[0040] For one example, see Figures 2 to 4 The liquid guiding member 20 is roughly a tubular structure with a preset length in the axial direction. For example, the length of the liquid guiding member 20 is less than the length of the bracket member 10 and greater than the axial length of the liquid inlet channel 10b; for the convenience of distinction and description, the tubular space of the liquid guiding member 20 is defined as the air guiding channel 20a, that is, the air guiding channel 20a is arranged along the axial direction through the liquid guiding member 20; the ventilation channel 20b is arranged on the side wall of the liquid guiding member 20 in the circumferential or radial direction, that is, the ventilation channel 20b is equivalent to being arranged along the radial direction through the side wall of the liquid guiding member 20.
[0041] As far as the structural coordination relationship between the liquid-guiding member 20 and the bracket member 10 is concerned, the liquid-guiding member 20 is equivalent to being coaxially inserted into the interior of the bracket member 10 in the form of a cover for the liquid inlet channel 10b. In this way, the air-guiding channel 20a and the assembly channel 10a can be kept coaxially connected to form a structural channel for air flow in and out of the atomizer core inside the atomizer core; at the same time, the ventilation channel 20b and the liquid inlet channel 10b can also be connected to each other, thereby providing structural support for accelerating the entry of the aerosol matrix into the liquid-guiding member 20.
[0042] See also Figures 2 to 4The heating element 30 and the liquid guiding element 20 are arranged in contact with each other. The heating element 30 can heat the aerosol matrix absorbed or stored in the atomized liquid guiding element 20 to generate a usable aerosol.
[0043] For one example, see Figure 2 and Figure 4 The heating element 30 includes a heating sheet 31 and an electrode pin 32; wherein the heating sheet 31 adopts a sleeve structure having a mesh structure and being axially bent to enclose or tend to enclose, and the heating sheet 31 is arranged in the air guide channel 20a in the form of contacting and fitting the inner wall of the liquid guide member 20 (which can be understood as the side wall of the air guide channel 20a); the electrode pin 32 is connected to the heating sheet 31, and one end of the electrode pin 32 is led out of the bracket member 10 from the assembly channel 10a, and an electrical connection relationship is established between the heating sheet 31 and the relevant functional components of the atomization device with the help of the electrode pin 32, so that the heating sheet 31 generates heat due to power supply, thereby heating the aerosol matrix absorbed or stored by the atomization liquid guide member 20.
[0044] In other embodiments, the heating element 30 may also adopt other suitable structures, for example, the heating element 30 is inserted into the side wall of the liquid guiding element 20; all of these will not be elaborated here.
[0045] Based on this, when the atomizer core is in the installed and applied state, when the airflow flows through the atomizer core through the assembly channel 10a and the air guide channel 20a, the aerosol matrix absorbed and stored by the liquid guide member 20 is heated and atomized by the heating element 30 to form an aerosol and can be discharged from the atomizer core along with the airflow (for example, the aerosol enters the air guide channel 20a or the assembly channel 10a from the gap between the heating plate 31 and the liquid guide member 20); at the same time, based on the structural connection relationship established by the ventilation channel 20b between the air guide channel 20a and the liquid inlet channel 10b, when the ventilation channel 20b is located on one side of the air guide channel 20a to form a negative pressure effect, the pressure balance between the inside and outside of the liquid guide member 20 is broken, so as to attract the aerosol matrix to enter the liquid guide member 20 through the liquid inlet channel 10b faster, thereby providing sufficient aerosol matrix for the liquid guide member 20 and the heating element 30, thereby stably generating aerosol and increasing the amount of aerosol generated, and ultimately ensuring that the atomizer core or atomization device can stably output aerosol and avoid the occurrence of problems such as dry burning.
[0046] It should be noted that Figure 2 The bold solid line with an arrow in the middle represents the approximate flow direction or flow path of the aerosol matrix. Figure 2 The bold dashed line with an arrow in the middle represents the approximate flow direction or flow path of the aerosol.
[0047] For one example, see Figure 3The liquid-guiding member 20 is an integrated structure made of microporous ceramic material. Based on the material properties of the heat-conducting member 20, firstly, it can achieve stable absorption and storage of the aerosol matrix; secondly, it can effectively enhance the stability and firmness of the structural combination between the bracket member 10, the liquid-guiding member 20 and the heating member 30; thirdly, it is conducive to reducing the production cost and assembly difficulty of the atomizer core.
[0048] For one example, see Figure 1 and Figure 3 The number of ventilation channels 20b and liquid inlet channels 10b is set to multiple, such as two, three, four or other greater numbers; taking the ventilation channel 20b as an example, the multiple ventilation channels 20b are evenly spaced along the circumferential direction or the geometric center line of the air guide channel 20a, and the multiple ventilation channels 20b are connected to the multiple liquid inlet channels 10b in a one-to-one manner.
[0049] Therefore, the use of multiple liquid inlet channels 10b can enable the liquid guiding component 20 to absorb and store the aerosol matrix circumferentially and evenly, thereby ensuring the uniformity of aerosol generation with the cooperation of the heating component 30; and with the help of multiple ventilation channels 20b, the pressure balance on the inside and outside of the liquid guiding component 20 can be stably and evenly broken, ensuring that the aerosol matrix enters the liquid guiding component 20 from the circumferential side of the liquid guiding component 20 as evenly and quickly as possible.
[0050] In other embodiments, according to the structural form of the liquid-guiding component 20, the bracket component 30 or the structural assembly relationship between the two, the same liquid inlet channel 10b can also be connected to multiple ventilation channels 20b at the same time, or the same ventilation channel 20b can be connected to multiple liquid inlet channels 10b at the same time, which will not be elaborated here.
[0051] For one example, see Figure 1 and Figure 3 The ventilation channel 20b is a strip-shaped through-hole structure with a preset length in the axial direction, or the axial size of the ventilation channel 20b is smaller than the axial size of the liquid inlet channel 10b, and the circumferential size of the ventilation channel 20b is smaller than the axial size of the ventilation channel 20b.
[0052] By selecting and configuring the shape or size of the ventilation channel 20b, the ventilation channel 20b can adapt to the path or direction of the airflow flowing through the air guide channel 20a, which is more conducive to breaking the pressure balance on the inside and outside of the liquid guide part 20, so as to guide the aerosol matrix to flow quickly into the liquid guide part 20.
[0053] It should be noted that considerations for setting the size or shape of the ventilation channel 20b may include ensuring that the aerosol matrix does not leak into the air guide channel 20a through the ventilation channel 20b when the atomizer core is in a static state, or maintaining pressure balance between the inside and outside of the liquid guide member 20. In other words, the size and shape of the ventilation channel 20b are specifically set while ensuring that the aerosol matrix does not leak into the air guide channel 20a through the ventilation channel 20b. Therefore, in some embodiments, the ventilation channel 20b may also adopt other suitable structural shapes or dimensions that are compatible with the liquid inlet channel 10b.
[0054] See also Figure 5 Combined with Figures 1 to 4 The embodiment of the present application further provides an atomization device, which includes a housing 40, a power supply assembly (not shown in the figure) and an atomization core of any of the aforementioned embodiments.
[0055] The housing 40 can be a single component or a combination of multiple components; it allows the atomizer device to be carried, moved, operated, and used. The power supply assembly can be understood as a collection of related functional components, such as a control module and a battery module. This power supply assembly can be located within the housing 40 or installed as an independent functional structure. The atomizer core is located within the housing 40 and is electrically connected to the power supply assembly. The power supply assembly can be used to control the atomizer core (specifically, the heating element 30) to start and stop heating and adjust the heating power of the heating element 30.
[0056] For example, see Figure 5 The outer shell 40 has an air inlet channel 40a for external air flow to enter and an air outlet channel 40b for the air flow to carry aerosol out; the bracket 10 is arranged between the air inlet channel 40a and the air outlet channel 40b, so as to construct an air flow channel between the liquid guide part 20 (specifically, the air guide channel 20a) and the outer shell 40 with the help of the bracket 10 (specifically, the assembly channel 10a) to guide the air flow into and out of the atomization device.
[0057] At the same time, a liquid storage chamber 40c for storing aerosol matrix is formed between the bracket member 10 and the outer shell member 40. The aerosol matrix in the liquid storage chamber 40c can enter the liquid guide member 20 through the liquid inlet channel 10b, and then the aerosol matrix in the atomized liquid guide member 20 is heated by the heating element 30. The generated aerosol can be discharged from the atomizing device along the airflow for ready use.
[0058] In the process of air flow passing through the liquid guide member 20 via the air guide channel 20a, the ventilation channel 20b can break the pressure balance between the air guide channel 20a and the liquid storage chamber 40c, so that the aerosol matrix can enter the liquid guide member 20 stably, evenly and quickly, thereby creating favorable conditions for stable aerosol generation and increasing the amount of aerosol generated.
[0059] In other embodiments, the liquid storage chamber 40a may also be formed in other forms inside the outer shell 40 and communicated with the interior of the atomizer core through the liquid inlet channel 10b; details are not repeated here.
[0060] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
