Description

Technical Field

[0001] This disclosure relates to the field of atomization technology, and more particularly to a heating element and an atomizing device. Background Technology

[0002] A vaporizer is an electronic delivery system that provides an aerosol to a user for inhalation. This device typically converts a vaporizing medium, either wholly or partially, into an aerosol by heating it. The vaporizing medium can be a liquid form such as e-cigarette liquid, medical drugs, or skin lotion, or it can be a solid or gel (e.g., e-cigarette paste). For solid or gel-based vaporizing media, the rate at which the vaporizing medium is supplied to the heating element directly determines the amount of aerosol inhaled by the user.

[0003] Therefore, there is a need for a heating core or atomizing device that can provide the atomizing matrix at a stable rate to further avoid insufficient or excessive aerosol supply, thereby enabling users to inhale aerosols at an effective and safe dosage. Utility Model Content

[0004] This disclosure aims to at least improve or alleviate one of the technical problems existing in the background art.

[0005] Therefore, an embodiment of the first aspect of this disclosure provides a heating element. The heating element includes a heating element comprising a heating portion; a heat-conducting and oil-conducting block comprising a first surface and a second surface located at opposite ends in a vertical direction, the first surface being configured to contact an atomizing matrix, and the heating portion being disposed on the second surface; and a first electrode and a second electrode, the heating portion being electrically connected between the first electrode and the second electrode. The heat-conducting and oil-conducting block is configured to conduct heat generated by the heating portion to the atomizing matrix and to transfer the atomizing matrix from the first surface to the second surface. Furthermore, the heating portion is configured to at least partially convert the atomizing matrix transferred to the second surface into an aerosol, and to allow the aerosol to exit the second surface at the heating portion.

[0006] When the aforementioned heating element is in operation, the heating element located on the second surface indirectly heats, through a heat-conducting and oil-conducting block, a paste-like atomizing matrix located on the first surface. After melting upon heating, the paste-like atomizing matrix is ​​transferred from the first surface to the second surface and heated and atomized into an aerosol at the heating element. Because the heat-conducting and oil-conducting block achieves indirect heat and mass transfer between the heating element and the atomizing matrix, the rate at which the atomizing matrix is ​​supplied to the heating element is stable and controllable, thereby enabling stable aerosol generation. This helps to avoid insufficient or excessive aerosol supply to a certain extent, allowing the user to inhale aerosol at an effective and safe dosage.

[0007] An embodiment of the second aspect of this disclosure provides an atomizing device, which includes a heating core as described in the above embodiments; a receiving cavity for receiving an atomizing matrix, a first surface defining the bottom surface of the receiving cavity in the vertical direction; and an atomizing cavity, wherein a heating element is exposed inside the atomizing cavity, such that the atomizing matrix is ​​heated and atomized at the heating element, then leaves the second surface and enters the atomizing cavity.

[0008] The above description is merely an overview of the technical solution disclosed herein. In order to better understand the technical means of this disclosure and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this disclosure more apparent and understandable, specific embodiments of this disclosure are described below.

[0025] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this disclosure are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0027] In this disclosure, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0028] In this document, “connection” refers to fluid connectivity, meaning that a fluid (including liquids and / or gases) can flow from one component to another. Furthermore, in this document, connectivity between two components can refer to direct connection between the two components, such as at least partial alignment between two holes, or connectivity via an intermediate medium.

[0029] In this disclosure, unless otherwise stated, all figures used in this specification and claims to represent component parameters, technical effects, etc., should in any instance be understood to be modified by the terms "approximately" or "roughly". Therefore, unless indicated to the contrary, the numerical parameters listed in the following specification and appended claims are approximate values. They will vary for those skilled in the art depending on the desired properties and effects sought to be obtained through this disclosure, and each numerical parameter should be interpreted according to the number of significant figures and conventional rounding methods or in a manner understood by those skilled in the art.

[0030] In this disclosure, the terminology used in the description of the various examples is for the purpose of describing particular examples only and is not intended to be limiting. Unless the context explicitly indicates otherwise, an element may be one or more unless the number of elements is specifically limited. Furthermore, the term "and / or" as used in this disclosure covers any one of the listed items and all possible combinations thereof.

[0031] "Atomizing matrix" refers to a mixture or auxiliary substance that can be wholly or partially atomized into an aerosol by an electronic device or similar device. Atomizing matrix can be liquid media such as e-cigarette liquid, medical drugs, and skin lotions. By atomizing these media, an aerosol that can be inhaled or absorbed can be delivered to the user.

[0032] "Aerosol" refers to a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gaseous medium.

[0033] A vaporizer is an electronic delivery system that provides an aerosol to a user for inhalation. This device typically converts a vaporizing medium, either wholly or partially, into an aerosol by heating it. The vaporizing medium can be a liquid form such as e-cigarette liquid, medical drugs, or skin lotion, or it can be a solid or gel (e.g., e-cigarette paste). For solid or gel-based vaporizing media, the rate at which the vaporizing medium is supplied to the heating element directly determines the amount of aerosol inhaled by the user.

[0034] In view of this, the present disclosure provides a heating core or atomizing device that can provide the atomizing matrix at a stable rate, further avoiding insufficient or excessive aerosol supply, thereby enabling users to inhale aerosol at an effective and safe dosage.

[0035] For ease of explanation, the following embodiments use a heating element and an atomizing device from one embodiment of this disclosure as examples.

[0036] Figure 1 and Figure 2 This is a schematic diagram of a heating element according to some embodiments of this disclosure. Figure 1 and Figure 2 As shown, the heating element 100 includes: a heating element 110, which includes a heating portion 111; a heat-conducting and oil-conducting block 120, which includes a first surface 121 and a second surface 122 located at opposite ends along the vertical direction D1, the first surface 121 being configured to contact the atomizing matrix, and the heating portion 111 being disposed at the second surface 122; and a first electrode 131 and a second electrode 132, the heating portion 111 being electrically connected between the first electrode 131 and the second electrode 132. The heat-conducting and oil-conducting block 120 is configured to conduct heat generated by the heating portion 111 to the atomizing matrix and to transfer the atomizing matrix from the first surface 121 to the second surface 122. Furthermore, the heating portion 111 is configured to at least partially convert the atomizing matrix transferred to the second surface 122 into an aerosol, and to allow the aerosol to leave the second surface 122 at the heating portion 111.

[0037] The heating element 111 contacts the second surface 122 of the heat-conducting and oil-conducting block 120, while the atomizing matrix to be atomized contacts the first surface 121 of the heat-conducting and oil-conducting block 120. When the heating element 111 is connected to the working circuit via the first electrode 131 and the second electrode 132, the heat generated by the heating element 111 is conducted from the second surface 122 of the heat-conducting and oil-conducting block 120 to the first surface 121, indirectly heating the atomizing matrix, causing at least a portion of the atomizing matrix, for example, solid or paste-like, to melt into a liquid state. It is understood that the aforementioned first surface 121 and second surface 122 are located at both ends of the heat-conducting and oil-conducting block 120 along the vertical direction D1.

[0038] The heat-conducting and oil-conducting block 120 can absorb liquid atomizing matrix and transfer the liquid atomizing matrix from the first surface 121 to the second surface 122. Since the heating element 111 is also arranged on the second surface 122, the heating element 111 further converts the atomizing matrix transferred to the second surface 122 into at least a portion of an aerosol, and the aerosol form of the atomizing matrix leaves the second surface 122 at the heating element 111. It is understood that the ability of the heat-conducting and oil-conducting block 120 to absorb and transfer liquid atomizing matrix can be achieved by machining the heat-conducting and oil-conducting block 120 to form a transfer channel for the liquid atomizing matrix, or by using a material that easily forms capillary pores inside the heat-conducting and oil-conducting block 120. This disclosure does not limit the specific structure or material of the heat-conducting and oil-conducting block 120.

[0039] In some embodiments, the first surface 121 is located above the second surface 122 in the vertical direction D1, such that the liquid atomized matrix can spontaneously transfer from the first surface 121 to the second surface 122 under the action of gravity.

[0040] Therefore, since the heat-conducting and oil-conducting block 120 achieves indirect heat and mass transfer between the heating element 111 and the atomizing matrix, the rate at which the atomizing matrix is ​​supplied to the heating element 111 is stable and controllable, thereby enabling the stable generation of aerosols. This helps to avoid insufficient or excessive aerosol supply to a certain extent, thus allowing users to inhale aerosols at an effective and safe dosage.

[0041] According to some embodiments of this disclosure, the heating element 110 further includes a sheet-like oil-blocking portion 112, which is configured to adhere to at least a portion of the second surface 122, thereby preventing the atomizing matrix from continuing to be transmitted in the vertical direction D1 at the oil-blocking portion 112.

[0042] like Figure 1 As shown, the oil-blocking part 112 can be a thin sheet structure with a small thickness along the vertical direction D1. After this thin sheet structure is attached to the second surface 122, the atomizing matrix transferred to the second surface 122 cannot leave the heat-conducting and oil-conducting block 120 and reach the vicinity of the heating part 111 in the area where the oil-blocking part 112 is provided. This can control the amount of aerosol generated at the heating part 111 to a certain extent, which helps to prevent excessive aerosol supply. At the same time, the oil-blocking part 112 can also prevent the atomizing matrix from seeping out from the second surface 122 at a position away from the heating part 111, which can prevent atomizing matrix leakage to a certain extent.

[0043] Therefore, by providing an oil-blocking part 112 at the heating element 110, the amount of aerosol generated at the heating element 111 can be controlled to a certain extent, and the leakage of the atomizing matrix can also be prevented to a certain extent.

[0044] Figure 3 This is a schematic diagram of the heating element 110 according to some embodiments of this disclosure. Figure 3 As shown, the heating element 110 includes a first heating part 1111 and a second heating part 1112, and the oil blocking part 112 includes a first oil blocking part 1121 and a second oil blocking part 1122. The first oil blocking part 1121, the first heating part 1111, the second oil blocking part 1122 and the second heating part 1112 are connected end to end to form a closed annular sheet structure.

[0045] like Figure 3As shown, the first heating element 1111 and the second heating element 1112 are arranged symmetrically to each other, and the first oil blocking element 1121 and the second oil blocking element 1122 are arranged symmetrically to each other. The first oil blocking element 1121, the first heating element 1111, the second oil blocking element 1122 and the second heating element 1112 are connected end to end to form a closed annular sheet structure.

[0046] In some embodiments, the first oil-blocking portion 1121 and the second oil-blocking portion 1122 are made of conductive material, and the first electrode 131 and the second electrode 132 are electrically connected to the first oil-blocking portion 1121 and the second oil-blocking portion 1122, respectively. Electrical connection to the first heating portion 1111 and the second heating portion 1112 can be achieved at any position within the closed annular sheet structure formed by the sequential connection of the first oil-blocking portion 1121, the first heating portion 1111, the second oil-blocking portion 1122, and the second heating portion 1112, which simplifies circuit connections.

[0047] Therefore, by setting two heating elements, it is beneficial to further improve heating and atomization efficiency. It is understood that more heating elements can be set, and this disclosure does not limit the number of heating elements.

[0048] In some embodiments, the second surface 122 of the heat-conducting and oil-conducting block 120 is circular, and the first oil-blocking part 1121, the first heating part 1111, the second oil-blocking part 1122 and the second heating part 1112 are connected end to end to form a closed annular sheet structure. The annular sheet structure is attached to the second surface 122 at a position close to the outer edge of the second surface 122.

[0049] According to some embodiments of this disclosure, the first surface 121 is a surface that protrudes along the vertical direction D1. As a result, the atomized matrix melted into liquid at the first surface 121 will accumulate at the outer edge of the first surface 121 under the action of gravity and be transferred vertically to the outer edge of the second surface 122, which to some extent facilitates a stable supply of atomized matrix to the first heating part 1111 and the second heating part 1112.

[0050] According to some embodiments of this disclosure, the heating element 111 includes a zigzag structure with reciprocating bends. This allows the heating element 111 to be arranged more compactly within a limited area, increasing its heat dissipation area. Simultaneously, the zigzag structure also improves the mechanical strength of the heating element 111 to some extent.

[0051] like Figure 3As shown, a fixing foot 140 is provided on the edge of the heating element 110. The fixing foot 140 is configured to fix the heating element 110 and the heat-conducting and oil-conducting block 120. The fixing foot 140 can be provided on the edge of the heating part 111 or on the edge of the oil-blocking part 112. Thus, the heating element 110 can be fixed to the heat-conducting and oil-conducting block 120 by means of the fixing foot 140.

[0052] According to some embodiments of this disclosure, the fixed foot 140 is angled relative to the edge of the heating element 110, and the fixed foot 140 is embedded in the heat-conducting and oil-conducting block 120.

[0053] According to some embodiments of this disclosure, the resistance of the heating element 111 is 0.2 to 3 ohms. Therefore, setting the resistance of the heating element 111 to 0.2 to 3 ohms makes the heat generation of the heating element 111 stable and controllable, which helps to avoid insufficient or excessive aerosol supply to a certain extent, thereby enabling the user to inhale aerosols at an effective and safe dosage.

[0054] According to some embodiments of this disclosure, the heat-conducting and oil-conducting block 120 has capillary pores capable of transferring the atomized matrix between the first surface 121 and the second surface 122.

[0055] According to some embodiments of this disclosure, the material of the heat-conducting and oil-conducting block 120 includes quartz, ceramic, glass, or mica. The heating element 110 can, for example, be sintered integrally with the heat-conducting and oil-conducting block 120. Capillary pores for oil conduction can be formed inside the quartz, ceramic, glass, or mica through chemical etching, or by integrally sintering quartz microspheres, ceramic powder, glass microspheres, or mica powder. Alternatively, the required capillary pores can be created in quartz or glass using a laser. Therefore, selecting quartz, ceramic, or mica as the material of the heat-conducting and oil-conducting block 120 facilitates the formation of capillary pores for oil conduction and controls the oil conduction rate.

[0056] An embodiment of the second aspect of this disclosure provides an atomizing device 10.

[0057] Figure 4 and Figure 5 These are cross-sectional views of the atomizing device 10 along different directions. For example... Figure 4 Figure 5 As shown, the atomizing device 10 includes a heating element 100 as described in the first aspect of this disclosure; a receiving cavity 200 for receiving an atomizing matrix, a first surface 121 defining the bottom surface of the receiving cavity 200 in the vertical direction D1; and an atomizing cavity 300, in which a heating element 111 is exposed, such that the atomizing matrix can enter the atomizing cavity 300 after leaving the second surface 122 at the heating element 111.

[0058] The receiving cavity 200 is a closed cavity for containing the atomizing matrix, and its bottom surface in the vertical direction D1 is defined by the first surface 121 of the heat-conducting and oil-conducting block 120. The second surface 122 of the heat-conducting and oil-conducting block 120 and the heating element 111 communicate with the internal space of the atomizing cavity 300, so that the atomizing matrix from the heating element 111, after being heated and atomized, leaves the second surface 122 and enters the atomizing cavity 300. At the same time, the atomizing cavity 300 is also in communication with the air outside the atomizing device 10, so that the atomizing matrix mixes with the air inside the atomizing cavity 300 to form an aerosol for the user to inhale.

[0059] Since the atomizing device 10 includes the heating element 100 of the first aspect of this disclosure, the atomizing device 10 can, to a certain extent, avoid insufficient or excessive aerosol supply, thereby enabling the user to inhale aerosol at an effective and safe dosage.

[0060] like Figure 4 As shown, the atomizing chamber 300 is located below the heating element 111 in the vertical direction D1.

[0061] Thus, a transmission path for the atomizing matrix is ​​formed sequentially along the vertical direction D1: "accommodating cavity 200 - first surface 121 - heat-conducting and oil-conducting block 120 - heating element 111 (or second surface 122) - atomizing cavity 300". Under the influence of gravity, the atomizing matrix, after being heated and melted, can spontaneously enter the containing cavity 200 through the aforementioned path, which to some extent helps to provide a relatively stable aerosol generation rate.

[0062] like Figure 4 As shown, the atomizing device 10 also includes an annular heat-conducting wall 210, which is a thin-walled structure arranged around the receiving cavity 200. The bottom of the annular heat-conducting wall 210 in the vertical direction D1 contacts the first surface 121.

[0063] The annular heat-conducting wall 210 is a thin-walled structure surrounding the receiving cavity 200. This thin-walled structure can extend a certain height along the vertical direction D1 and define the receiving cavity 200 along the transverse direction D2. The bottom of the annular heat-conducting wall 210 in the vertical direction D1 contacts the first surface 121, so that the heat generated by the heating part 111 can be conducted to the annular heat-conducting wall 210 through the first surface 121.

[0064] In some embodiments, the annular heat-conducting wall 210 is made of a metallic material in order to achieve better heat conduction.

[0065] Therefore, when the atomizing substrate is placed inside the receiving cavity 200, the atomizing substrate comes into contact with the annular heat-conducting wall 210, so that the annular heat-conducting wall 210 can heat the atomizing substrate from the side, which is beneficial to preheating the atomizing substrate located in the receiving cavity 200 and avoids the phenomenon of the atomizing substrate sticking to the wall.

[0066] Figures 6 to 8 This is a schematic diagram illustrating the fit between the heat-conducting and oil-conducting block 120 and the seal 500 according to some embodiments of this disclosure. Figures 6 to 8 As shown, the atomizing device 10 also includes a sealing element 500, which is fitted to the second surface 122. The sealing element 500 has a through groove 510 at a location corresponding to the heating element 111. The sealing element 500 is disposed between the second surface 122 and the atomizing chamber 300, and except at the location of the through groove 510, the sealing element 500 isolates the second surface 122 and the atomizing chamber 300. Therefore, the sealing element 500 can, to a certain extent, prevent leakage of the atomizing matrix from locations other than the through groove 510 (i.e., the heating element 111).

[0067] The sealing member 500 has a first hole 521 and a second hole 522 at the positions corresponding to the first battery cell and the second battery cell, for the first battery cell 131 and the second battery cell 132 to pass through.

[0068] In some embodiments, the atomizing device 10 further includes an oil storage groove 600, which is located below the atomizing chamber 300 in the vertical direction D1. The position and shape of the oil storage groove 600 match the position and shape of the heating element 110. Thus, by providing the oil storage groove 600 to collect the liquid atomizing matrix that may leak from the heating element 111, it is beneficial to prevent atomizing matrix leakage.

[0069] See Figure 9 and Figure 10 The oil reservoir 600 is formed, for example, by a support 700 having a centrally located protrusion 710 and surrounding sidewalls 720, with the oil reservoir 600 formed between the protrusion 710 and the surrounding sidewalls 720. The protrusion 710 abuts against the heating element 110 to support the heating element 110 and the atomizing matrix located above the heating element 110. The sidewalls 720 are lower than the protrusion 710 in the vertical direction D1 to provide a channel for airflow.

[0070] In some embodiments, the atomizing device 10 further includes an oil-absorbing cotton 610, which is configured to absorb the atomizing matrix inside the oil storage groove 600. The oil-absorbing cotton 610 may be disposed at the bottom of the oil storage groove 600 or in a separate space communicating with the oil storage groove 600.

[0071] In some embodiments, at least a portion of the oil-absorbing cotton 610 is below the bottom of the oil storage groove 600, so that the liquid atomizing matrix in the groove 600 can flow to the oil-absorbing cotton 610 under the action of gravity, thereby improving the oil absorption effect.

[0072] For example, see Figure 9 and Figure 10The support 700 also has a partition wall 730 that forms the bottom of the oil storage groove 600 and separates the cavity between the protrusion 710 and the side wall 720 into an upper oil storage groove 600 and a lower first cavity 741. At least one through hole 731 is provided in the partition wall 730 for guiding the liquid atomizing matrix in the oil storage groove 600 into the first cavity 741 located below the partition wall 730. Oil-absorbing cotton 610 is disposed, for example, in the first cavity 741. Alternatively, as... Figure 9 As shown, it is disposed in the second cavity 742 of the protrusion 710, which communicates with the first cavity 741.

[0073] The top of the sidewall 720 is higher than the spacer wall 730 in the first direction D1 to prevent leakage of liquid atomized matrix falling on the spacer wall 730.

[0074] Therefore, by setting up the oil-absorbing cotton 610, it is beneficial to prevent the leakage of liquid atomized matrix in the oil storage groove 600.

[0075] In some embodiments, the atomizing device 10 further includes an air inlet 410 and an exhaust 420, which communicate with the top of the atomizing chamber 300 along the vertical direction D1. This, to a certain extent, prevents leakage of any liquid atomizing matrix that may be present at the bottom of the atomizing chamber 300 or within the oil storage groove 600 via the air inlet 410 and / or the exhaust 420.

[0076] like Figure 4 As shown, the air intake duct 410, the atomizing chamber 300, and the exhaust duct 420 extend along the longitudinal direction of the atomizing device 10. The first oil-blocking part 1121 and the first heating part 1111 are arranged symmetrically about this longitudinal direction so that the airflow entering through the air intake duct 410 can fully carry away the aerosol formed by atomization.

[0077] In some embodiments, the air intake duct 410 and the exhaust duct 420 may be integrally formed with the bracket 700.

[0078] like Figure 4 As shown, the atomizing device 10 also includes a housing 800 extending at least partially along the transverse direction D2. The housing 800 includes an air inlet 810 and a mouthpiece 820 distributed at both ends of the transverse direction D2. A receiving cavity 200 is located at the end of the housing 800 away from the mouthpiece 820, and the receiving cavity 200 opens in a direction away from the atomizing chamber 300. The air inlet 810, the air intake 410, the atomizing chamber 300, the exhaust 420, and the mouthpiece 820 are sequentially connected. The housing 800 may also include a handle 830 for the user to hold the atomizing device 10.

[0079] In some embodiments, the air intake duct 410 and the exhaust duct 420 are both defined by the housing 800 and the bracket 700.

[0080] like Figure 4 As shown, the atomizing device 10 also includes a power supply assembly 900, which is electrically connected to the first electrode 131 and the second electrode 132.
