Description

Technical Field

[0001] This invention relates to the field of aerosol generation device technology, and more particularly to a heating component and atomizing device. Background Technology

[0002] Atomizers are common products in daily life, primarily used to heat and atomize the aerosol-generating matrix they contain into an aerosol for users to inhale, providing a stimulating and pleasurable sensation. Specifically, an atomizer contains an wicking element and a heating element. The heating element is located on one side of the wicking element, while the other side allows the aerosol-generating matrix to permeate into the heating element, which then heats and atomizes the permeated matrix, forming an aerosol. However, existing wicking elements only have one type of seepage hole, the size of which is difficult to control. If the hole diameter is too large, leakage is likely; if the diameter is too small, the aerosol-generating matrix cannot permeate sufficiently, leading to dry burning. Therefore, it is necessary to provide a heating component that redesigns the wicking element to solve these problems. Summary of the Invention

[0003] Therefore, it is necessary to provide a heating component and atomizing device to address the problem that existing atomizers only have one size of oil leakage hole in the oil guide body, which leads to easy oil leakage or dry burning of the atomizer.

[0004] This invention provides a heating assembly, comprising:

[0005] An oil guide body includes an oil guide layer, an intermediate layer, and an oil-locking layer stacked sequentially. The oil guide layer, the intermediate layer, and the oil-locking layer are respectively provided with a first oil guide hole, a second oil guide hole, and a third oil guide hole. The diameters of the first oil guide hole, the second oil guide hole, and the third oil guide hole decrease sequentially, and the first oil guide hole, the second oil guide hole, and the third oil guide hole are connected in sequence. The first oil guide hole is connected to the outside of the oil guide body.

[0006] A heating element is disposed on the side of the oil-locking layer facing away from the intermediate layer. The heating element is connected to the third oil guide hole. The heating element is used to generate matrix heating and atomization of the aerosol seeping out of the third oil guide hole to form an aerosol.

[0007] The aforementioned heating component directly contacts the aerosol generating matrix through the side of the oil-guiding layer facing away from the intermediate layer. The aerosol generating matrix is ​​guided through the larger-diameter oil-guiding holes in the oil-guiding layer into the secondary-diameter oil-guiding holes in the intermediate layer, and finally into the smallest-diameter oil-guiding holes in the oil-locking layer, contacting the heating element on the outer surface of the oil-locking layer to achieve heating and atomization of the aerosol generating matrix. This multi-layered structure and the step-by-step penetration, diffusion, and refinement design of the aerosol generating matrix solve the oil leakage problem. Simultaneously, the aerosol generating matrix can fully flow onto the heating element, preventing dry burning of the heating element and resulting in aerosols with a good taste.

[0008] In one embodiment, at least one of the first oil guide hole, the second oil guide hole, and the third oil guide hole includes a first through hole and a second through hole, wherein the diameter of the first through hole and the diameter of the second through hole are different, and the first through hole and the second through hole are interconnected.

[0009] In one embodiment, the extension direction of the first through hole is set at an angle to the extension direction of the second through hole.

[0010] In one embodiment, the oil guiding layer further has a first secondary oil hole, which is connected to the first oil guiding hole, and the extension direction of the first secondary oil hole is arranged at an angle to the extension direction of the first oil guiding hole.

[0011] And / or the intermediate layer also has a second auxiliary oil hole, which communicates with the second oil guide hole, and the extension direction of the second auxiliary oil hole is arranged at an angle to the extension direction of the second oil guide hole;

[0012] And / or the oil-locking layer also has a third auxiliary oil hole, which is connected to the third oil guide hole, and the extension direction of the third auxiliary oil hole is arranged at an angle to the extension direction of the third oil guide hole.

[0013] In one embodiment, the oil guiding layer further has a fourth auxiliary oil hole, which is interconnected with the first auxiliary oil hole and the first oil guiding hole. The extension directions of the fourth auxiliary oil hole, the first auxiliary oil hole, and the first oil guiding hole are perpendicular to each other.

[0014] In one embodiment, the diameter of the oil guiding holes on the oil guiding layer is greater than or equal to 40 micrometers and less than or equal to 50 micrometers.

[0015] In one embodiment, the diameter of the oil guide holes on the oil-locking layer is greater than or equal to 5 micrometers and less than or equal to 15 micrometers.

[0016] In one embodiment, the diameter of the oil guide holes on the intermediate layer is greater than 15 micrometers and less than 40 micrometers.

The two ends of the heating element are respectively connected to the first electrode sheet and the second electrode sheet. The heating element has multiple heating holes through it, and the multiple heating holes are arranged in a honeycomb pattern.

[0026] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the specific details described below are only a part of the embodiments of the present invention, and the present invention can be implemented in many other embodiments different from those described herein. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] The present invention provides an atomizing device 100, which can store an aerosol generating matrix and heat and atomize the aerosol generating matrix to form an aerosol for users to inhale.

[0030] The atomizing device 100 includes a housing 101 and a heating component 102 disposed within the housing. The housing 101 has a accommodating cavity 1011 for storing the aerosol generating matrix. The accommodating cavity 1011 is in communication with the outer surface (oil guiding surface 1021) of the heating component 102 so that the aerosol generating matrix in the accommodating cavity 1011 can flow to the oil guiding surface 1021.

[0031] One end of the housing 101 has an air inlet 1012, and the other end has a mouthpiece 1013. The housing 101 also contains an atomizing channel 1014, one end of which connects to the outside of the housing 101, and the other end connects to the air inlet 1012, which in turn connects to the outside of the housing 101. When the heating element 102 generates aerosol, the aerosol is dispersed in the atomizing channel 1014. The user can inhale through the mouthpiece 1013 to allow outside air to enter the atomizing channel 1014 through the air inlet 1012. The airflow mixes with the aerosol in the atomizing channel 1014 and is then inhaled by the user from the other end.

[0032] The accommodating cavity 1011 is positioned above the heating component 102, and is directly connected to the oil guiding surface 1021 of the heating component or connected through an intermediate oil passage. When the accommodating cavity contains an aerosol generating matrix, under the influence of gravity, the aerosol generating matrix in the accommodating cavity will flow directly to the oil guiding surface 1021, then enter the interior of the heating component 102 from the oil guiding surface 1021, and finally flow to the side of the heating component 102 opposite to the oil guiding surface 1021. The heating component 102 heats and atomizes the infiltrated aerosol generating matrix into an aerosol for the user to inhale.

[0033] It should be emphasized that during the process of the aerosol generating matrix flowing from the oil guiding surface 1021 to the other side of the heating component, the aerosol generating matrix can quickly penetrate, which is beneficial to improving atomization efficiency. At the same time, the aerosol generating matrix can be confined to the column, making it less prone to leakage.

[0034] refer to Figure 1 and Figure 2 The heating assembly 102 includes an oil guide body 1, a heating element 2 and two electrode rods 3. One side of the heating element 2 is connected to the oil guide body 1, and the other side of the heating element 2 is connected to the two electrode rods 3. The ends of the two electrode rods 3 away from the heating element 2 are exposed outside the housing 101.

[0035] The surface of the oil guide 1 facing away from the heating element 2 is the aforementioned oil guide surface 1021. The oil guide surface 1021 is connected to the accommodating cavity 1011 and is used to contact the aerosol generation matrix. When the outer shell 101 is connected to the power supply unit, the two electrode rods 3 can be connected to the positive and negative terminals of the power supply unit respectively to supply power to the heating element 2. Thus, the heating element 2 can heat and atomize the aerosol generation matrix that permeates from the oil guide 1 into aerosol.

[0036] Figure 3 The oil guide body 1 of the embodiment shown includes an oil guide layer 11, an intermediate layer 12, and an oil locking layer 13 stacked in sequence. The oil guide layer 11, the intermediate layer 12, and the oil locking layer 13 are respectively provided with a first oil guide hole 111, a second oil guide hole 121, and a third oil guide hole 131. The diameters of the first oil guide hole 111, the second oil guide hole 121, and the third oil guide hole 131 decrease sequentially, and the first oil guide hole 111, the second oil guide hole 121, and the third oil guide hole 131 are connected in sequence. The first oil guide hole 111 is connected to the outside of the oil guide body 1.

[0037] It can be understood that the aforementioned oil-guiding surface 1021 is the surface of the oil-guiding layer 11 facing away from the intermediate layer 12. The heating element 2 is located on the side of the oil-locking layer 13 facing away from the intermediate layer 12, and the heating element 2 is connected to the third oil-guiding hole 131. The heating element 2 is used to heat and atomize the aerosol seeping from the third oil-guiding hole 131 to form an aerosol.

[0038] The aerosol generating matrix directly contacts the oil guiding surface 1021. Under its own gravity, the aerosol generating matrix flows sequentially through the first oil guiding hole 111, the second oil guiding hole 121, and the third oil guiding hole 131 to the heating element 2. The heating element 2 then heats and atomizes the aerosol generating matrix. Because the apertures of the first oil guiding hole 111, the second oil guiding hole 121, and the third oil guiding hole 131 decrease sequentially, the aerosol generating matrix is ​​less prone to leakage during its flow to the heating element 2. Simultaneously, the aerosol generating matrix can fully flow onto the heating element 2, preventing the heating element from dry-burning. This results in aerosols with a good taste produced by heating and atomizing the aerosol generating matrix.

[0039] Specifically, in the embodiment, when the user uses the atomizing device 100, the aerosol generating matrix in the accommodating cavity 1011 flows into the oil guiding surface 1021 under the action of gravity. The aerosol generating matrix will diffuse and permeate along the first oil guiding hole 111 of the oil guiding layer 11 to the intermediate layer 12. Since the diameter of the second oil guiding hole 121 of the intermediate layer 12 is smaller than the diameter of the first oil guiding hole 111, and the diameter of the second oil guiding hole 121 is larger than the diameter of the third oil guiding hole 131 of the oil locking layer 13, the intermediate layer 12 not only plays the role of transferring the aerosol generating matrix from the oil guiding layer 11 to the oil locking layer 13, but also plays a certain role of oil storage, oil locking and oil buffering. When the aerosol generating matrix enters the oil-locking layer 13 from the second oil guide hole 121 of the intermediate layer 12, the capillary force of the third oil guide hole 131 will lock the aerosol generating matrix, preventing it from flowing back or overflowing. At the same time, compared with the traditional method of relying solely on the permeation effect of ceramics, the third oil guide hole 131 on the oil-locking layer 13 can enable the aerosol generating matrix to flow to the heating element 2 more quickly, so that the heating element 2 can heat and atomize it to form an aerosol for the user to inhale.

[0040] The oil-guiding layer 11, the intermediate layer 12, and the oil-locking layer 13 can be single-layer or multi-layer structural layers.

[0041] refer to Figure 3 , Figure 3 In the embodiment shown, the oil guiding layer 11, intermediate layer 12, and oil locking layer 13 each have only one layer of oil guiding holes, so the oil guiding layer 11, intermediate layer 12, and oil locking layer 13 are all single-layer structures.

[0042] refer to Figure 4 , Figure 4 The oil guiding layer 11 in the illustrated embodiment has a multi-layer structure. The first oil guiding hole 111 of the oil guiding layer 11 includes a first through hole 1111 and a second through hole 1112 that are connected. The diameter of the first through hole 1111 is larger than the diameter of the second through hole 1112, and both the diameters of the first through hole 1111 and the second through hole 1112 are larger than the diameter of the second oil guiding hole 121. The first through hole 1111 communicates with external air, and the second through hole 1112 communicates with the second oil guiding hole 121.

[0043] It is understood that in other embodiments, the number of through-hole layers included in the oil guiding layer 11 may be three or more, and the vertical arrangement order of the through-holes in each layer is not limited. In addition, the diameter of the through-holes in each layer is larger than the diameter of the second oil guiding hole 121.

[0044] It is understandable that the intermediate layer 12 and the oil-locking layer 13 mentioned above can also be configured with a multi-layer through-hole structure, just like the oil-guiding layer 11, which is beneficial for more effective output of the aerosol matrix and oil locking.

[0045] Since the oil guide body 1 includes an oil guide layer 11, an intermediate layer 12, and an oil locking layer 13 stacked sequentially, and the oil guide holes 140 on the three layers are set to have progressively smaller diameters according to their different functions, the oil guide body 1 can be configured to better perform the functions of oil guiding and oil locking by limiting the diameter of the oil guide holes on the oil guide layer 11, the intermediate layer 12, and the oil locking layer 13.

[0046] In one embodiment, the diameter of the first oil guide hole 111 of the oil guiding layer 11 can be set to be greater than or equal to 40 micrometers and less than or equal to 50 micrometers; the diameter of the second oil guide hole 121 of the intermediate layer 12 can be set to be greater than 15 micrometers (e.g., 16 micrometers) and less than 40 micrometers (e.g., 39 micrometers); and the diameter of the third oil guide hole 131 of the oil locking layer 13 can be set to be greater than or equal to 5 micrometers and less than or equal to 15 micrometers.

[0047] Of course, the diameters of the first oil guide hole 111, the second oil guide hole 121, and the third oil guide hole 131 mentioned above can also be values ​​within other ranges, which are not limited here.

[0048] refer to Figure 5 , Figure 5 In addition to the first oil guide hole 111, the oil guiding layer 11 of the embodiment shown also has a first secondary oil hole 112 and a fourth secondary oil hole 113. The fourth secondary oil hole 113, the first secondary oil hole 112 and the first oil guide hole 111 are interconnected so that the aerosol generation matrix can flow more quickly and evenly throughout the oil guiding layer 11 through the fourth secondary oil hole 113, the first secondary oil hole 112 and the first oil guide hole 111, so as to improve the atomization efficiency.

[0049] The extending directions of the fourth auxiliary oil hole 113, the first auxiliary oil hole 112, and the first guide oil hole 111 are perpendicular to each other. This can be understood as the extending directions of the fourth auxiliary oil hole 113, the first auxiliary oil hole 112, and the first guide oil hole 111 respectively being along... Figure 5 The X, Y, and Z axes in the coordinate system are arranged in the following directions. In other embodiments, the extension directions of the fourth auxiliary oil hole 113, the first auxiliary oil hole 112, and the first guide oil hole 111 can also be set at other angles, such as 45° or 60°, etc., which are not limited here.

[0050] Both the first auxiliary oil hole 112 and the fourth auxiliary oil hole 113 do not penetrate the oil guiding layer 11 to prevent the aerosol matrix from leaking out from the side of the oil guiding layer 11. It should be noted that... Figure 5 The embodiment shown has a portion cut off on both right-angled sides of the oil guiding layer 11 to clearly show the first auxiliary oil hole 112 and the fourth auxiliary oil hole 113.

[0051] refer to Figure 6 The heating element 2 includes a first electrode plate 21, a second electrode plate 22, and a heating element 23. The two ends of the heating element 23 are connected to the first electrode plate 21 and the second electrode plate 22, respectively. The first electrode plate 21 and the second electrode plate 22 are respectively used to connect the ends of two electrode rods 3, thereby electrically connecting them to the positive and negative terminals of an external main power supply to power the heating element 23. When the heating element 23 heats up, the high temperature generated by the heating element 23 can heat and atomize the aerosol generating matrix into an aerosol.

[0052] Figure 6 The heating element 23 in the illustrated embodiment is "S"-shaped. This shape of the heating element 23 is beneficial for increasing the heating area and improving atomization efficiency. Of course, in other embodiments, it can also be other shapes, such as "X"-shaped, "Y"-shaped, etc., which are not limited here.

[0053] refer to Figure 7 , Figure 7 The heating element 23 in the illustrated embodiment is honeycomb-shaped, meaning that multiple heating holes 231 are formed throughout the heating element 23 along its thickness direction. Each heating hole 231 is a regular hexagon, and the multiple heating holes 231 together form a honeycomb structure. The heating element 23 in this embodiment has a larger heating area, which can further increase the atomization efficiency of the aerosol generating matrix and improve the aerosol taste. It is understood that in other embodiments, the heating element 23 can also have other shapes, such as multiple heating holes arranged in a matrix, which is not limited here.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications, substitutions, and improvements without departing from the concept of the present invention, and these should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of this invention should be determined by the claims.
