Description

Technical Field

[0001] This application belongs to the field of electronic cigarette atomizing component technology, specifically, this application relates to an electronic cigarette atomizing core and an electronic cigarette. Background Technology

[0002] The atomizing core is an important component in electronic atomizing devices. It mainly consists of a porous body and a heating element placed on the surface of the porous body. The porous body is connected to the oil reservoir that stores the atomized liquid, which can conduct the atomized liquid to the heating element. The atomized liquid is then heated by the heating element to achieve atomization.

[0003] However, the heating element of current ceramic atomizing cores on the market is obtained by printing electronic paste directly onto a porous body, followed by high-temperature baking, electrode connection, and lead wire processing. Although the total atomizing end area of ​​existing porous bodies is relatively large, the effective heating area of ​​the atomizing core accounts for a small proportion of the total area due to the shape of the heating element and the influence of heat transfer on the carrier. Moreover, due to the large volume of the porous body, the heat loss of the heating element is relatively large, reducing the utilization rate of thermal energy of the electronic cigarette heating element. Summary of the Invention

[0057] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0058] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0059] Reference Figures 1 to 6 This application provides an electronic cigarette atomizing core 100 for use in electronic cigarettes. The electronic cigarette atomizing core 100 includes:

[0060] The porous body 1 and the heating element 3 are provided. The porous body 1 includes a liquid absorption end and an atomizing end. A protrusion 2 is provided on the atomizing end. The protrusion 2 has an end face away from the porous body 1 and a side face located on the outer periphery of the protrusion. The side face is the peripheral side face adjacent to the end face.

[0061] The e-liquid inside the electronic cigarette seeps from the suction end to the atomizing end. The heating element 3 is disposed on the end face, that is, on the side of the protrusion 2 away from the porous body 1, and at least a portion of the heating element 3 is less than a predetermined distance from the edge of the end face, so that at least a portion of the end face and at least a portion of the side face form an atomizing surface. Therefore, the end face and side face of the protrusion 2 can be fully utilized, avoiding an excessively large atomizing surface area on the end face of the protrusion 2. Thus, while fully utilizing the atomizing surface formed by the protrusion 2, the effective atomizing area of ​​the atomizing surface can be guaranteed while increasing the heating rate of the heating element 3, thereby improving the heating efficiency of the heating element and the atomization volume of the electronic cigarette atomizing core.

[0062] In one specific embodiment, the heating element 3 is bent circumferentially along the protrusion 2 to form at least one raised segment and / or at least one recessed segment. At least one edge of the end face matches the contour of the heating element 3, for example, at least one edge of the end face is equidistant from the contour edge of the heating element 3. When heated, the heating element 3 can atomize the e-liquid on the atomizing surface to provide the user with vapor that can be inhaled.

[0063] The protrusion 2 avoids an excessively large atomization surface area. While fully utilizing the atomization surface formed by the protrusion 2, the heating element ensures full utilization of the atomization surface, improving its efficiency. The heating element 3 is bent circumferentially along the protrusion 2 to form at least one raised section and / or at least one recessed section. The raised section can heat and atomize the edge or even the side of the protrusion 2, while the recessed section can heat and atomize the central part of the surface of the protrusion 2 away from the porous body 1. When at least one edge of the end face of the protrusion 2 matches the contour of the heating element 3, the heating element 3 can uniformly heat the surface and side of the protrusion 2 during heating, ensuring the effective atomization area and improving the heating efficiency of the heating element 3.

[0064] The electronic cigarette atomizing core 100 provided in this embodiment has a protrusion 2 on the atomizing end of the porous body 1, and a heating element 3 is disposed on the side of the protrusion 2 away from the porous body 1, so that an atomizing surface is formed on the protrusion 2. The heating element 3 is bent to form at least one raised section and / or at least one recessed section, and at least one edge of the end face matches the contour of the heating element 3. The protrusion 2 can avoid setting an excessively large atomizing surface area. When making full use of the atomizing surface formed by the protrusion 2, the heating of the heating element 3 can ensure that the atomizing surface is fully utilized, thus ensuring the utilization efficiency of the atomizing surface while improving the heating rate of the heating element 3. When at least one edge of the end face matches the contour of the heating element 3, the heating element 3 can uniformly heat the middle and side of the protrusion 2 when heating, so as to ensure the effective atomization area of ​​the atomizing surface, improve the heating efficiency of the heating element 3 and the atomization amount of the electronic cigarette atomizing core 100, and ensure the atomization effect of the electronic cigarette atomizing core 100.

[0065] In addition, the structural design of the electronic cigarette atomizing core 100 can also prevent the atomization temperature of the heating element 3 from being too high, thereby reducing harmful substances in the aerosol after the e-liquid is atomized, which is beneficial to the health of the user and enhances the user's trust in electronic cigarettes.

[0066] Optionally, the edge contour of the end face forms a raised edge that is adapted to the raised segment at a location corresponding to the raised segment;

[0067] And / or, the edge profile of the end face forms a recessed edge that is adapted to the recessed segment at a location corresponding to the recessed segment.

[0068] Specifically, when at least one edge of the end face of the protrusion 2 matches the contour of the heating element 3, the heating element 3 can uniformly heat the surface and sides of the protrusion 2 when heating, thereby improving the heating efficiency of the heating element 3. The matching of the end face of the protrusion 2 with the contour of the heating element 3 can specifically mean that the edge contour of the end face forms a protruding edge that adapts to the protruding segment at a location corresponding to the protruding segment, such that the protruding edge of the end face is equidistant from the protruding segment; or that the edge contour of the end face forms a concave edge that adapts to the concave segment at a location corresponding to the concave segment, such that the concave edge of the end face is equidistant from the concave segment.

[0069] Optionally, see Figure 1 and Figure 2 The heating element 3 is arranged in a square wave shape on the end face.

[0070] Specifically, see Figure 1 The square-wave-shaped heating element 3 may include a first bent segment and a second bent segment, with the bending directions of the first bent segment and the second bent segment being opposite. The two ends of the heating element 3 are respectively a first connecting segment and a second connecting segment. The heating element 3 also includes a first heating segment, a second heating segment, and a third heating segment. The first heating segment connects the first connecting segment and the first bent segment, the second heating segment connects to both the first bent segment and the second bent segment, and the third heating segment connects the second bent segment and the second connecting segment. The first bent segment and the second bent segment may each form a protruding segment, and the first heating segment, the second heating segment, and the third heating segment may each form a recessed segment. The first connecting segment and the second connecting segment extend to both ends of the first atomization area. The first heating segment, the second heating segment, the third heating segment, the first bent segment, and the second bent segment provide the main heat source for the heating element 3, providing uniform heating to the atomization surface.

[0071] Optionally, see Figure 3 and Figure 4 The heating element 3 is arranged in a zigzag shape on the end face.

[0072] Specifically, see Figure 3The zigzag-shaped heating element 3 includes a first bent segment and a second bent segment, with the bending directions of the first and second bent segments opposite. The two ends of the heating element 3 are a first connecting segment and a second connecting segment, respectively. The heating element 3 also includes a first heating segment connected between the first and second bent segments. The first and second bent segments each form a protruding segment, and the first heating segment forms a recessed segment. The first and second connecting segments extend to both ends of the first atomization area. The first heating segment, the first bent segment, and the second bent segment provide the main heat source for the heating element 3, enabling even heating of the atomization surface.

[0073] Optionally, the heating element 3 is arranged in an S-shape on the end face. That is, the heating element 3 has a structure symmetrical to the S-shaped heating element 3, which also ensures even heating of the atomizing surface. Additionally, see... Figure 5 The heating element 3 may include two symmetrical upper and lower sections, each of which can be bent to form multiple protruding sections and multiple recessed sections; or see [other source]. Figure 6 The heating element 3 may include two symmetrical upper and lower sections, each of which can be bent to form a protruding section.

[0074] Optionally, see Figure 7 and Figure 8 The heating element 3 is arranged in a wave shape on the end face.

[0075] Specifically, when the heating element 3 is wavy, it can be bent to form multiple protruding segments and multiple recessed segments. One side profile of the wavy heating element 3 can match the edge of the end face of the protrusion 2. For example, one side edge of the heating element 3 can be evenly spaced from the edge of the end face of the protrusion 2. Figure 7 As shown; or the two sides of the heating element 3 can be matched with the edge of the end face of the protrusion 2, for example, the two sides of the heating element 3 are set at equal intervals with the edge of the end face of the protrusion 2, so that the end face of the protrusion 2 also forms a wavy end face.

[0076] Optionally, see Figure 9 and Figure 10 The heating element 3 is arranged in an arc shape on the end face.

[0077] Specifically, when the heating element 3 is arc-shaped, it can be bent to form a protruding section. One side contour of the arc-shaped heating element 3 can match the edge of the end face of the protrusion 2, for example, the outer edge of the heating element 3 and the edge of the end face of the protrusion 2 can be equally spaced. Alternatively, both sides of the arc-shaped heating element 3 can match the edge of the end face of the protrusion 2, for example, both sides of the heating element 3 and the edge of the end face of the protrusion 2 can be equally spaced, so that the end face of the protrusion 2 also forms an arc-shaped end face. Figure 9 As shown.

[0078] Optionally, the distance between the overall outline of the heating element 3 and the edge of the end face ranges from 0.05 to 4.0 mm.

[0079] Specifically, at least one edge of the end face matches the contour of the heating element 3. For example, at least one edge of the end face of the protrusion 2 is equidistant from the contour edge of the heating element 3, which ensures the uniformity of heating and atomization of this edge of the end face of the protrusion 2. To further improve the heating uniformity of the end face and even the side of the protrusion 2, the overall contour of the heating element 3 can be matched with the edge of the end face, so that the distance between the overall contour of the heating element 3 and the edge of the end face is controlled within the range of 0.05-4.0 mm.

[0080] Optionally, see Figure 1 , Figure 3 and Figure 5 The distance h between the protruding section and the end face edge of the protrusion 2 is in the range of 0.1-2.0 mm, preferably 0.5-1.0 mm;

[0081] And / or, the distance between the recessed section and the edge of the end face ranges from 0.1 to 4.0 mm, preferably from 0.5 to 2.0 mm.

[0082] Specifically, when the contour of the heating element 3 matches the edge of the end face of the protrusion 2, the raised section and / or the recessed section can be equally spaced from the edge of the end face of the protrusion 2. By controlling the distance h between the raised section and / or the recessed section and the edge of the end face of the protrusion 2 within the range of 0.1-2.0 mm, the raised section can heat and atomize the edge of the end face of the protrusion 2 and even the side surface of the protrusion 2, while ensuring the effective atomization area of ​​the atomizing surface, thereby improving the atomization efficiency of the heating element 3.

[0083] Optionally, the protrusion 2 is integrally formed with the porous body 1.

[0084] Specifically, the material of the protrusion 2 and the porous body 1 can be the same, for example, both can be porous ceramic materials. The protrusion 2 and the porous body 1 can be integrally formed in a mold, and then their shapes can be fixed through processes such as firing. Alternatively, the protrusion 2 can also be obtained by cutting after forming a regular atomizing core. This application embodiment does not limit the forming method of the protrusion 2.

[0085] Optionally, see Figures 1 to 6 The electronic cigarette atomizing core 100 also includes a terminal block 4, which is connected to both ends of the heating element 3;

[0086] The ratio of the area of ​​the terminal block 4 to the area of ​​the end face is 0.02-0.25, preferably 0.15-0.2.

[0087] In some implementations, see Figures 1 to 6 The junction box 4 is disposed on the end face, and electrodes are disposed on the junction box 4 for electrical connection with an external power source. The end of the junction box 4 can be configured as an arc shape, so that the ratio of the area of ​​the junction box 4 to the area of ​​the end face is controlled within the range of 0.02-0.25. This avoids excessive occupation of the end face area of ​​the protrusion 2 by the area of ​​the junction box 4, and reduces the absorption of heat from the heating element 3 by the junction box 4, thereby improving the atomization efficiency of the heating element 3.

[0088] Specifically, the electrodes on the terminal block 4 may include positive and negative electrodes. When the heating element 3 is used in an electronic cigarette, voltage is applied to the positive and negative electrodes through the power supply inside the electronic cigarette, thus energizing the heating element 3. When energized, the heating element 3 can convert electrical energy into heat energy. When the heating element 3 heats up, it can atomize the e-liquid at the atomizing end of the electronic cigarette atomizing core 100, ensuring the atomization effect of the electronic cigarette.

[0089] Optionally, the height of the protrusion 2 is in the range of 0.1-5mm, preferably 0.5-1.5mm.

[0090] Specifically, the design of the protrusion 2 avoids an excessively large atomizing surface area. While fully utilizing the atomizing surface formed by the protrusion 2, the heating element 3 ensures that the atomizing surface is fully utilized, thereby increasing the heating rate of the heating element 3 and guaranteeing the utilization efficiency of the atomizing surface. However, if the height of the protrusion 2 is too low, it is difficult to form a significant end face on the protrusion 2, hindering the placement of the heating element 3. Conversely, if the height of the protrusion 2 is too high, it occupies too much volume of the e-cigarette atomizing core 100 and increases the penetration path of the e-cigarette oil, reducing the atomization efficiency of the e-cigarette atomizing core 100.

[0091] See Figure 11 and Figure 12 This application also provides an electronic cigarette, which includes the aforementioned electronic cigarette atomizing core 100.

[0092] Specifically, the electronic cigarette atomizing core 100 has a protrusion 2 on the atomizing end of the porous body 1. The heating element 3 has the protrusion 2 on the side away from the porous body 1, so that an atomizing surface is formed on the protrusion 2. The heating element 3 is bent to form at least one raised section and / or at least one recessed section. The outline of the heating element 3 matches the edge of the protrusion 2. The protrusion 2 avoids an excessively large atomizing surface area. When fully utilizing the atomizing surface formed by the protrusion 2, the heating of the heating element ensures that the atomizing surface is fully utilized. This improves the heating rate of the heating element 3 and ensures the utilization efficiency of the atomizing surface. When the outline of the heating element 3 matches the edge of the protrusion 2, the heating element 3 can uniformly heat the middle and sides of the protrusion 2 when heating, ensuring the effective atomizing area of ​​the atomizing surface, improving the heating efficiency of the heating element 3 and the atomization amount of the electronic cigarette atomizing core 100, and ensuring the atomization effect of the electronic cigarette.

[0093] Optionally, see Figure 11 and Figure 12 The electronic cigarette also includes a housing 101, an oil storage chamber 102 disposed within the housing 101, and an atomizing core sealing element 108. The atomizing core sealing element 108 is sleeved on the porous body 1, and the atomizing core sealing element 108 at least covers a portion of the outer peripheral surface of the porous body 1 and the edge of the liquid-absorbing end.

[0094] Specifically, when the atomizing core sealing element 108 is sleeved on the porous body 1, that is, when the atomizing core sealing element 108 is sleeved on the outer periphery of the atomizing core 100, it can effectively seal the e-liquid on the liquid absorption surface and prevent the e-liquid from leaking.

[0095] Optionally, the electronic cigarette further includes:

[0096] The upper support 103, the lower support 104, and the lower cover 105 are provided, with the lower cover 105 covering the open end of the housing 101; the lower cover 104 has an air inlet 1051.

[0097] The upper support 103 and the lower support 104 cooperate to form a receiving cavity, and the electronic cigarette atomizing core 100 is disposed in the receiving cavity;

[0098] The upper support 103 is provided with an oil guide hole 1032, and the liquid absorption end of the porous body 1 is connected to the oil storage tank 102 through the oil guide hole 1032; an atomizing chamber 106 is formed between the atomizing surface and the lower support 104, and the lower support 104 is provided with a vent hole that is connected to the air inlet 1051.

[0099] Specifically, when the electronic cigarette atomizing component is working, the e-liquid flowing out of the oil storage tank 102 is guided to the liquid absorption end of the porous body 1 through the oil guide hole 1032, and absorbed by the capillary action of the porous body 1 to the heating element 3 at the atomizing end of the porous body 1. It is then atomized into mist by the heating element 3. At this time, under the suction action of the user in the air outlet channel 1011, the air in the air inlet 1051 is driven into the atomizing chamber 106, carrying the aerosol of the atomizing chamber 106 and being discharged to the air outlet channel 1011. As the e-liquid is continuously absorbed by the porous body 1 to replenish the heating element 3, a negative pressure is formed in the oil storage tank 102. Under the action of the negative pressure, external air can pass through the atomizing chamber 106 and the electronic cigarette atomizing core 100, and then enter the oil guide hole 1032 and the oil storage tank 102 to form a pressure balance, ensuring that the e-liquid can be smoothly introduced into the porous body 1.

[0100] Optionally, see Figure 11 and Figure 12 The electronic cigarette also includes an upper support sealing element 107 and a lower cover sealing element 109;

[0101] The upper support sealing element 107 is sleeved on the outer periphery of the upper support 103. The outer edge of the upper support sealing element 107 abuts against the inner wall of the housing 101 to enclose and form the oil storage tank 102. The upper support sealing element 107 has a first connecting hole 1071 for connecting the oil storage tank 102 and the oil guide hole 1032. The upper support sealing element 107 has a second connecting hole 1072 for connecting the air outlet channel 1011 and the air outlet 1031.

[0102] The atomizing core sealing element 108 is sleeved on the outer periphery of the electronic cigarette atomizing core 100; the lower cover sealing element 109 is arranged around the outer periphery of the lower cover 105, and the outer edge of the lower cover sealing element 109 abuts against the inner wall of the housing 101.

[0103] Specifically, the upper bracket sealing element 107, the atomizing core sealing element 108, and the lower cover sealing element 109 provide the necessary sealing inside the electronic cigarette, preventing unnecessary communication between the oil reservoir 102 and the connection gaps of each component, effectively preventing oil leakage. Additionally, the electronic cigarette includes a liquid absorption element 1010, which is arranged around the outer periphery of the air inlet 1051 and is used to absorb condensate flowing out of the air inlet 1051.

[0104] Optionally, the electronic cigarette includes:

[0105] The outer casing, and the liquid storage chamber located within the outer casing;

[0106] The lower base is connected to the outer shell to form a receiving cavity, and an air intake channel is provided on the lower base;

[0107] An atomizing core seal is located within the receiving cavity. The atomizing core seal is sleeved on the porous body 1 of the electronic cigarette atomizing core 100, and the atomizing core seal is interference-fitted with the outer shell and the porous body 1.
