The horizontal ceramic heat conductor includes an airflow channel provided on the upper portion for concentrated airflow to enter and exit. Compared to heat-conducting ceramic bodies without airflow channels, vertical heat-conducting ceramic bodies, and horizontal heat-conducting ceramic bodies with dispersed airflow, the horizontal ceramic heat conductor has the advantages of high flavor reproduction, resistance to flavor loss, low powder loss during assembly, a relatively simple and compact structure, and low air intake resistance.

Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and in particular to a horizontal ceramic heat conductor, a heating element, an electronic atomization device and an electronic atomizer. Background Art

[0002] Electronic vaporizers generally refer to e-cigarettes. E-cigarettes are electronic products that mimic cigarettes, with the same appearance, smoke, taste, and feel. They are powered by a rechargeable lithium polymer battery and offer a flavor profile similar to, and even more than, regular cigarettes. They also offer the same smoke, taste, and feel as regular cigarettes. They are primarily used for smoking cessation and as a replacement for cigarettes. E-cigarettes are also a non-combustion alternative to regular cigarettes. They share some of the same characteristics as regular cigarettes, offering a boost of energy and satisfying the pleasure and habit smokers have developed over years. However, they are fundamentally different from regular cigarettes. E-cigarettes do not burn, contain tar, or produce the over 460 chemicals that can cause respiratory and cardiovascular diseases when regular cigarettes are burned. Thus, they eliminate the carcinogens found in regular cigarettes and avoid the harmful effects of "secondhand smoke" or environmental pollution.

[0003] The heater, a core component within the electronic atomizer, heats the e-liquid and converts it into smoke, achieving the desired atomization effect. Existing heaters typically utilize thermally conductive ceramic as a heat conductor. An electrical heating circuit layer is printed on the ceramic, electrically connected to the heating circuit layer via electrodes. This circuit layer is energized and generates heat, which is then transferred to the ceramic body. This heat is then more efficiently utilized, allowing the e-liquid in contact with the ceramic body to be more fully atomized, forming smoke.

[0004] However, the thermal conductive ceramics of existing electronic atomizers still have the following problems:

[0005] 1. For thermally conductive ceramic bodies without integrated airflow channels—that is, the entire body serves solely as a heat-conducting component, lacking any internal or surface airflow channels—external airflow must flow in through the peripheral plastic components used to assemble the thermally conductive ceramic body. This peripheral plastic component must have airflow channels to allow for external airflow to better guide and carry away the smoke produced by atomized e-liquid. The mixture of smoke and airflow produces an aerosol, which is generally directly inhaled by the user. Compared to the temperature of the smoke itself, the temperature of the incoming airflow is lower. When the smoke and airflow mix, the resulting aerosol will experience some condensation. Furthermore, due to the complex composition of e-liquid and the significant differences in physical properties such as boiling points among the various components in the smoke, this can lead to uneven condensation of the various aerosol components. This can significantly deviate between the proportions of the components in the aerosol actually inhaled and those in the e-liquid, resulting in a "loss of flavor."

[0006] 2. For vertical thermal conductive ceramic bodies, they generally have cylindrical, square or irregular cylindrical structures. In traditional technologies, there are also cases where vertical thermal conductive ceramic bodies have air guide channels in the vertical length direction (height direction), that is, the airflow from the outside will enter through the hollow air guide channels of the vertical thermal conductive ceramic body, but the smoke oil is generally in direct contact with the side walls of the vertical thermal conductive ceramic body, that is, the side walls of the vertical thermal conductive ceramic body heat the smoke oil into smoke, and then mix with the external airflow entering through the hollow air guide channels of the vertical thermal conductive ceramic body, but There are at least two major problems with vertical thermally conductive ceramic bodies. First, due to the large aspect ratio of the vertical thermally conductive ceramic body, when the vertical thermally conductive ceramic body is inserted into the installation position opened in the plastic part, the side wall of the vertical thermally conductive ceramic body will have a large degree of friction with the inner wall of the installation position, resulting in the problem of "powder falling" on the side wall of the vertical thermally conductive ceramic body; second, due to the relatively large aspect ratio of the vertical thermally conductive ceramic body, the structure of the vertical thermally conductive ceramic body in the length direction is not simple and compact enough, and the length of the cigarette cartridge will be forced to be increased when designing the product structure.

[0007] 3. For horizontal thermal conductive ceramic bodies, they generally have a flat structure, for example, a horizontal rectangular structure or a stepped horizontal terrace structure. The most core difference between them and vertical thermal conductive ceramic bodies is that the top surface of the horizontal thermal conductive ceramic body is in direct contact with the e-liquid, that is, the side wall of the horizontal thermal conductive ceramic body is in direct sealing contact with the structural parts without the need to directly heat the e-liquid. In this way, it is ensured that the vertical length direction (height direction) is much smaller than the vertical thermal conductive ceramic body, the problem of "powder falling" during assembly can be basically solved, and the structure is simpler and more compact. In traditional technology, there is also a situation where air flow channels are directly opened in a horizontal thermally conductive ceramic body. In the industry's cognition, in order to make the air flow entering from the outside and the smoke generated by heating on the top surface of the horizontal thermally conductive ceramic body be mixed evenly as much as possible to form a more dispersed and uniform smoke (aerosol) for users to inhale, the traditional technology is to open more small holes in the horizontal thermally conductive ceramic body, that is, a design of dispersed airflow outflow, or a dispersed and spaced multi-airflow channel design. The air flow entering from the outside is diverted and enters these small holes separately, and finally dispersedly converges into the atomization chamber. These large number of small holes are especially concentrated on the periphery of the horizontal thermally conductive ceramic body. The air flow entering from the outside is introduced and dispersed by the dispersed and spaced multi-airflow channels, and after flowing out from the top surface of the horizontal thermally conductive ceramic body, it is evenly mixed with the smoke. However, there are at least two major problems with the horizontal heat-conducting ceramic body's distributed spaced multiple airflow channels. One is that the design ignores the fact that the smoke oil will cover or submerge the outlet end of the distributed spaced multiple airflow channels, that is, the design of the distributed outflow of the airflow causes the air intake resistance to increase. In order to maintain the smoothness of the airflow, it is forced to open more dense, that is, more airflow channels to overcome. The second and most easily overlooked problem is the "loss of taste", or the problem of poor taste restoration. This is because the use of distributed spaced multiple airflow channels, although the aerosol formed after the airflow and smoke are mixed is evenly dispersed, it is not consistent with the atomization chamber (horizontal) The degree of contact between the aerosol and the side wall of the cavity (where the thermally conductive ceramic body is located) increases dramatically. Since tobacco oil adheres to the side wall of the atomization cavity, when the aerosol contacts the tobacco oil on the inner wall of the atomization cavity, the temperature of the tobacco oil is lower than that of the aerosol. In addition, since the composition of tobacco oil is relatively complex, the physical properties such as the boiling point of each component in the aerosol vary greatly, which will lead to uneven condensation of the components in the aerosol. The ratio of each component re-dissolved in the tobacco oil is quite different from the ratio of the original tobacco oil, resulting in a large difference between the ratio of each component in the aerosol actually inhaled and the ratio of each component in the tobacco oil, that is, the problem of "loss of taste" occurs.

[0008] In summary, traditional thermal conductive ceramic bodies have problems such as loss of taste, easy powder loss during assembly, insufficiently simple and compact structure, and large air intake resistance. Summary of the Invention

[0009] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a horizontal ceramic heat conductor, a heating element, an electronic atomization device and an electronic atomizer with high taste restoration, not easy to lose taste, not easy to lose powder during assembly, relatively simple and compact structure and small air intake resistance.

[0010] The object of the present invention is achieved through the following technical solutions:

[0011] A horizontal ceramic heat conductor is provided with an air flow channel for air flow to enter and flow out in a concentrated state.

[0012] In one embodiment, a window-shaped or slot-shaped air flow channel is opened on the edge of the horizontal ceramic heat conductor, and the air outlet end of the air flow channel is located on the top surface of the horizontal ceramic heat conductor, so that the air flow enters and flows out of the air flow channel in a concentrated state.

[0015] In one embodiment, the number of the air flow channels is 1 to 8.

[0016] In one embodiment, there are two air flow channels, the air inlet end and the air outlet end of the air flow channel both have a long strip groove structure, and the two air flow channels are axially symmetrically distributed about the central axis of the horizontal ceramic heat conductor.

[0017] In one embodiment, the horizontal ceramic heat conductor includes a ceramic body and a buckle body, the buckle body is arranged on the ceramic body, and the gap between the buckle body and the ceramic body is used to form the air flow channel.

[0018] In one embodiment, the air outlet end of the air flow channel is located between the buckle body and the ceramic main body, and the air outlet end of the air flow channel is also located on the top surface of the horizontal ceramic heat conductor. A first notch is provided on the bottom surface of the ceramic main body, and a second notch is provided on the side wall of the buckle body. The first notch and the second notch are connected to each other to form the air inlet end of the air flow channel.

[0019] In one embodiment, the inner wall of the air flow channel has a stepped structure, so that the air flow flows through the air flow channel in a non-linear state.

[0020] In one embodiment, the horizontal ceramic heat conductor has a rectangular structure or a terraced structure, and the top surface of the horizontal ceramic heat conductor is used to heat the e-liquid.

[0021] A heating element comprises the horizontal ceramic heat conductor described in any of the above embodiments, and also comprises an electrically conductive heating element, wherein the electrically conductive heating element is arranged on the horizontal ceramic heat conductor and is used to generate heat after being energized to transfer heat to the horizontal ceramic heat conductor.

[0022] In one embodiment, the electrically conductive heating element is a conductive heating printed layer, and the conductive heating printed layer is located on the top surface of the horizontal ceramic heat conductor.

[0023] In one embodiment, the electrically heated element is an electrically heated metal piece, and the electrically heated metal piece is mounted on the horizontal ceramic heat conductor.

[0024] In one embodiment, the heating element further includes a conductive connector, which is electrically connected to the energized heating element and is used to supply power to the energized heating element.

[0025] In one embodiment, the heating element further includes an electrode, and the electrode is used to be electrically connected to the conductive connector.

[0026] In one embodiment, the heating element further includes a heat-insulating sleeve, which is sleeved with the horizontal ceramic heat conductor, and the side wall of the horizontal ceramic heat conductor is sealed against the inner wall of the heat-insulating sleeve.

[0027] In one embodiment, the heat-insulating sleeve is provided with a smoke oil diversion and dispersion channel, and the top surface of the horizontal ceramic heat conductor is arranged toward the smoke oil diversion and dispersion channel.

[0028] In one embodiment, the heating element further includes a smoke oil dispersion guide body, which is buckled on the thermal insulation sleeve, and the smoke oil dispersion guide body is provided with a smoke oil dispersion guide area, and the smoke oil dispersion guide area is connected to the smoke oil diversion and dispersion channel.

[0029] An electronic atomization device comprises the heating element and an oil storage element, wherein the oil storage element is mounted on the heating element.

[0030] In one embodiment, an oil storage cavity is provided in the oil storage component, and the oil storage cavity is used to communicate with the heating component. A suction nozzle is provided on the oil storage component, and an air suction channel is provided on the oil storage component. The atomizing end of the air suction channel is arranged toward the heating component, and the air suction end of the air suction channel is communicated with the suction nozzle.

[0031] An electronic atomizer comprises the electronic atomization device and a power supply device, wherein the power supply device is used to be electrically connected to the heating element.

[0032] Compared with the prior art, the present invention has at least the following advantages:

[0033] For the heat-conducting ceramic body whose overall structure does not have an air flow channel, since the air flow channel of the horizontal ceramic heat conductor can directly allow external air flow to enter and flow out in a concentrated state, and the side wall of the horizontal ceramic heat conductor is also completely covered by the thermal insulation sleeve, the air flow entering from the outside does not need to flow through the peripheral plastic part, nor does it need to be provided with an air flow channel on the peripheral plastic part. The structure is simpler and more compact. The most important thing is that since the external air flow enters and flows out of the air flow channel of the horizontal ceramic heat conductor in a concentrated state, the air intake resistance is smaller. At the same time, the air flow flowing out of the air flow channel in a concentrated state is more concentrated, the air intake volume is larger, and it can quickly entrain the smoke generated by the heated tobacco oil. The aerosol formed after mixing rarely contacts the inner wall of the atomization chamber. The aerosol enters the inhalation channel and the air nozzle in a more linear flow direction. In this way, the contact between the aerosol and the tobacco oil on the inner wall of the atomization chamber is greatly reduced, thereby greatly reducing the degree of condensation between the aerosol and the tobacco oil, thereby making the taste of the aerosol inhaled higher and less likely to be lost.

[0034] Secondly, compared with the vertical thermal conductive ceramic body, the horizontal thermal conductive ceramic body has a flat structure, and the depth that needs to be inserted into the thermal insulation sleeve is much smaller than the depth of the vertical thermal conductive ceramic body. When assembling the vertical thermal conductive ceramic body, the friction between the horizontal thermal conductive ceramic body and the thermal insulation sleeve is smaller, and the insertion stroke is shorter, which can better reduce the powder loss problem. Moreover, since the height of the horizontal thermal conductive ceramic body is lower than that of the vertical thermal conductive ceramic body, there is no need to be forced to increase the length of the cartridge.

[0035] Finally, for the horizontal thermally conductive ceramic body with a dispersed airflow outflow design, due to the use of a porous dispersed interval multi-airflow channel design, when the air flows out from the air outlet of each airflow channel, the interaction between the airflows will produce a relatively chaotic gas vortex problem in the atomization chamber, thereby causing the entire airflow system and the subsequently formed aerosol system to greatly increase the degree of contact with the e-liquid adhered to the inner wall of the atomization chamber, thereby aggravating the condensation problem, thereby causing the loss of taste and poor taste restoration. Here, taking the components of e-liquid as an example, it includes the following compounds: propylene glycol (boiling point 187.3°C), cis-3-hexene-1-ol (boiling point 157°C), n-hexanol (boiling point 157°C), amyl acetate (boiling point 216.4°C), benzoic acid (boiling point 249.2°C), glycerol (boiling point 290°C), saline (boiling point 247°C), ethylene glycol monophenylpropionate (boiling point 288°C), etc. It can be seen from the components and the corresponding boiling points that there are large differences. Therefore, the aerosol with a higher temperature is mixed with the e-liquid with a lower temperature, and the uneven condensation degree of each component is the most critical factor causing the loss of taste. In the horizontal heat-conducting ceramic body of this case, the gas The airflow flowing out of the air outlet end of the flow channel in a gathered state is more concentrated, the air output is larger and more linear, and can quickly carry away the smoke generated by the heated tobacco oil. The aerosol formed after mixing rarely contacts the inner wall of the atomization chamber, and the aerosol flows into the air inlet channel and the air nozzle in a more linear direction. In this way, the contact between the aerosol and the tobacco oil on the inner wall of the atomization chamber is greatly reduced, thereby greatly reducing the degree of condensation between the aerosol and the tobacco oil, thereby making the taste of the aerosol inhaled higher and less likely to be lost. At the same time, the airflow flowing out in a gathered state can quickly break through the tobacco oil covering or shielding the air inlet end, thereby making the air intake resistance smaller.

The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0051] like Figure 1 As shown, it is a structural schematic diagram of an electronic atomizer 20 according to an embodiment. The electronic atomizer 20 includes an electronic atomization device 30 and a power supply device 21. The power supply device 21 is used to be electrically connected to the heating element 30. The power supply device 21 includes a shell, an MCU control module, a power supply module and a power connection terminal. The MCU control module, the power supply module and the power connection terminal are all installed in the shell. The power connection terminal is used to be directly electrically connected to the heating element 30. Specifically, the power connection terminal is used to be electrically connected to the electrode. The MCU control module is used to perform a control function, and the power supply module performs a power supply function, so that the electronic atomizer 20 can achieve an electronic atomization effect.

[0052] like Figure 2 As shown, it is a structural diagram of an electronic atomization device 30 according to an embodiment. The electronic atomization device 30 includes a heating element 40 and an oil storage element 31. The oil storage element 31 is installed on the heating element 40. The oil in the oil storage element 31 is output to the heating element 40, and the heating element 40 heats and atomizes the oil.

[0053] Please also refer to Figure 3 and Figure 4 The oil storage member 31 is provided with an oil storage chamber 31a, and the oil storage chamber 31a is used to communicate with the heating member 40. The oil storage member 31 is provided with a suction nozzle 31b, and the oil storage member 31 is provided with an air intake channel 31c. The atomization end of the air intake channel 31c is arranged toward the heating member 40, and the air intake end of the air intake channel 31c is communicated with the suction nozzle 31b. In this way, when the tobacco oil flows from the oil storage chamber 31a to the heating member 40, the heating member 40 heats the tobacco oil and atomizes the tobacco oil, and then mixes it with the fresh air entering from the outside to form smoke that can be inhaled, that is, to form an atomized aerosol. The aerosol enters the air intake channel 31c from the atomization end of the air intake channel 31c, and then flows out from the air intake end of the air intake channel 31c, that is, the user can inhale the aerosol through the suction nozzle 31b.

[0054] like Figure 5As shown, it is a structural schematic diagram of a heating element 40 of an embodiment. The heating element 40 includes a horizontal ceramic heat conductor 10 and an electric heating element (not shown in the figure). The electric heating element is arranged on the horizontal ceramic heat conductor 10. The electric heating element is used to generate heat after being energized to transfer heat to the horizontal ceramic heat conductor 10. When the electric heating element generates heat, it will transfer the heat to the horizontal ceramic heat conductor 10. When the tobacco oil contacts the top surface of the horizontal ceramic heat conductor 10, the horizontal ceramic heat conductor 10 will heat the tobacco oil and achieve an atomization effect.

[0055] In one embodiment, the energized heating element is a conductive heating printed layer, and the conductive heating printed layer is located on the top surface of the horizontal ceramic thermal conductor. That is to say, the top surface of the horizontal ceramic thermal conductor is used as a printing substrate, and a printing process is used to adhere the resistor paste to the top surface of the horizontal ceramic thermal conductor. After sintering or other curing operations, the conductive heating printed layer and the horizontal ceramic thermal conductor form an integrated structure. In this way, when the conductive heating printed layer is energized and heated, the heat will be transferred to the horizontal ceramic thermal conductor. At the same time, the conductive heating printed layer heats the cigarette oil directly or indirectly, thereby improving the heating effect and thus improving the atomization effect.

[0056] In one embodiment, the electrically heated element is an electrically heated metal piece, which is mounted on the horizontal ceramic heat conductor. Specifically, the electrically heated metal piece is fixed on the horizontal ceramic heat conductor by means of built-in or patch installation. When the electrically heated metal piece is electrically heated, it transfers heat to the horizontal ceramic heat conductor.

[0057] See also Figure 8 The heating element 40 also includes a conductive connector 41, which is electrically connected to the energized heating element. The conductive connector 41 is used to supply power to the energized heating element so that the energized heating element can achieve a self-heating effect when energized.

[0058] Please also refer to Figure 7 and Figure 8 The heating element 40 also includes an electrode 42, which is used to electrically connect to the conductive connector 41. In this way, the power supply device supplies power to the electrode 42, and then supplies power to the conductive connector 41 through the electrode 42, thereby finally realizing the heating element being energized and heating.

[0059] Please also refer to Figure 7 and Figure 8The heating element 40 also includes an insulating sleeve 43, which is sleeved with the horizontal ceramic heat conductor 10, and the side wall of the horizontal ceramic heat conductor 10 is also sealed against the inner wall of the insulating sleeve 43. The insulating sleeve 43 is mainly used to keep the horizontal ceramic heat conductor 10 warm and insulate, and is also used to fix, support and protect the horizontal ceramic heat conductor 10. At the same time, the insulating sleeve 43 is also used to assemble with its surrounding structural parts to make the overall structure more stable and reliable.

[0060] See also Figure 8 The thermal insulation sleeve 43 is provided with a smoke oil diversion and dispersion channel 43a, and the top surface of the horizontal ceramic heat conductor 10 is arranged toward the smoke oil diversion and dispersion channel 43a. When the smoke oil flows from the oil storage chamber to the thermal insulation sleeve, since the thermal insulation sleeve 43 is provided with the smoke oil diversion and dispersion channel 43a, the smoke oil will be diverted and dispersed by the smoke oil diversion and dispersion channel 43a, thereby enabling the smoke oil to be more evenly dispersed on the top surface of the horizontal ceramic heat conductor 10, and the heating uniformity is higher.

[0061] Please also refer to Figure 5 and Figure 7 The heating element 40 further includes a smoke oil dispersion and diversion body 44, which is pressed on the heat insulation sleeve 43, and the smoke oil dispersion and diversion body is provided with a smoke oil dispersion and diversion area 44a, and the smoke oil dispersion and diversion area 44a is connected with the smoke oil diversion and dispersion channel 43a. In this way, when the smoke oil flows out of the oil storage chamber, it will flow to the smoke oil dispersion and diversion area 44a in advance, and after the first dispersion and diversion operation, it will then flow into the smoke oil diversion and dispersion channel 43a, and after the second dispersion and diversion operation, it can more fully perform a double diversion and dispersion operation on the smoke oil.

[0062] like Figure 9 As shown, it is a structural schematic diagram of a horizontal ceramic heat conductor 10 according to an embodiment. The horizontal ceramic heat conductor 10 is provided with an air flow channel 100 for air flow to enter and flow out in a concentrated state. That is, when air flow enters or is inhaled in a negative pressure state, the air flow enters the air inlet end of the air flow channel 100 of the horizontal ceramic heat conductor 10 in a concentrated state, and when the air flow flows out of the air outlet end of the air flow channel 100 of the horizontal ceramic heat conductor 10, the air flow also flows out in a concentrated state.

[0063] First, for the heat-conducting ceramic body whose overall structure does not have an air flow channel, since the air flow channel 100 of the horizontal ceramic heat conductor 10 can directly allow the external air flow to enter and flow out in a concentrated state, and the side wall of the horizontal ceramic heat conductor 10 is also completely covered by the thermal insulation sleeve, the air flow entering from the outside does not need to flow through the peripheral plastic parts, nor does it need to be provided with an air flow channel on the peripheral plastic parts. The structure is simpler and more compact. The most important thing is that since the external air flow enters and flows out of the air flow channel 100 of the horizontal ceramic heat conductor 10 in a concentrated state, the air intake resistance is reduced. The force is smaller, and at the same time, the airflow flowing out of the airflow channel 100 in a gathered state is more concentrated, the air intake volume is larger, and the smoke generated by the heated tobacco oil can be quickly entrained. The aerosol formed after mixing rarely contacts the inner wall of the atomization chamber, and the aerosol flows into the air inlet channel and the air nozzle in a more linear direction. In this way, the contact between the aerosol and the tobacco oil on the inner wall of the atomization chamber is greatly reduced, thereby greatly reducing the degree of condensation between the aerosol and the tobacco oil, thereby making the taste of the aerosol inhaled higher and less likely to be lost.

[0064] Secondly, with respect to the vertical thermally conductive ceramic body, the horizontal thermally conductive ceramic body 10 has a flat structure, and the depth to which it needs to be inserted into the thermal insulation sleeve is much smaller than that of the vertical thermally conductive ceramic body. When assembling the vertical thermally conductive ceramic body, the friction between the horizontal thermally conductive ceramic body and the thermal insulation sleeve is smaller, and the insertion stroke is shorter, which can better alleviate the problem of powder falling. Moreover, since the height of the horizontal thermally conductive ceramic body is lower than that of the vertical thermally conductive ceramic body, there is no need to be forced to increase the length of the cartridge.

[0065] Finally, for the horizontal thermally conductive ceramic body with a dispersed airflow outflow design, due to the use of a porous dispersed interval multi-airflow channel design, when the air flows out from the air outlet of each airflow channel, the interaction between the airflows will produce a relatively chaotic gas vortex problem in the atomization chamber, thereby causing the entire airflow system and the subsequently formed aerosol system to greatly increase the degree of contact with the e-liquid adhered to the inner wall of the atomization chamber, thereby aggravating the condensation problem, thereby causing the loss of taste and poor taste restoration. Here, taking the components of the e-liquid as an example, it includes the following compounds: propylene glycol (boiling point 187.3°C), cis-3-hexene-1-ol (boiling point 157°C), n-hexanol (boiling point 157°C), amyl acetate (boiling point 216.4°C), benzoic acid (boiling point 249.2°C), glycerol (boiling point 290°C), saline (boiling point 247°C), ethylene glycol monophenyl propionate (boiling point 288°C), etc. It can be seen from the components and the corresponding boiling points that there are large differences. Therefore, the aerosol with a higher temperature is mixed with the e-liquid with a lower temperature, and the uneven condensation degree of each component is the most critical factor causing the loss of taste. In the horizontal heat-conducting ceramic body 10 of this case, the gas The airflow flowing out of the outlet end of the flow channel 100 in a concentrated state is more concentrated, and the air output is larger and more linear, which can quickly entrain the smoke generated by the heated tobacco oil. The aerosol formed after mixing rarely contacts the inner wall of the atomization chamber, and the aerosol flows into the inhalation channel and the air nozzle in a more linear direction. In this way, the contact between the aerosol and the tobacco oil on the inner wall of the atomization chamber is greatly reduced, thereby greatly reducing the degree of condensation between the aerosol and the tobacco oil, thereby making the taste of the aerosol inhaled higher and less likely to be lost. At the same time, the airflow flowing out in a concentrated state can quickly break through the tobacco oil covering or shielding the air inlet end, thereby making the air intake resistance smaller.

[0066] In one embodiment, a window-shaped or slot-shaped air flow channel is provided at the edge of the horizontal ceramic heat conductor, and the air outlet end of the air flow channel is located on the top surface of the horizontal ceramic heat conductor, so that the air flow enters and flows out of the air flow channel in a concentrated state. In this way, by providing a window-shaped or slot-shaped air flow channel at the edge of the horizontal ceramic heat conductor, and the air outlet end of the air flow channel is located on the top surface of the horizontal ceramic heat conductor, compared with the porous dispersed spaced multi-air flow channel design, the air flow can enter and flow out of the air flow channel in a concentrated state. Furthermore, the air flow direction of the air outlet end of the air flow channel is perpendicular to the top surface of the horizontal ceramic heat conductor, so that the air flow is better in a concentrated state and has a lower degree of contact with the inner wall of the atomization chamber.

[0067] In one embodiment, the air inlet end and / or the air outlet end of the air flow channel has a long strip groove structure. Figure 10 The outlet end of the air flow channel 100 has a long slot structure. Please refer to Figure 10 and Figure 11 The air outlet end of the air flow channel 100 has a long groove structure, so that the air flow of the air flow channel can enter and flow out in a more concentrated state, and the degree of contact with the inner wall of the atomization chamber is lower.

[0068] In one embodiment, the air inlet end and / or the air outlet end of the air flow channel has a square, circular, elliptical, polygonal, diamond, trapezoidal, arched, arc-shaped or special-shaped groove structure, so that the air flow of the air flow channel can enter and flow out in a more concentrated state and have a lower degree of contact with the inner wall of the atomization chamber.

[0069] It should be noted that the number of the air flow channels is 1 to 8. Of course, the number of the air flow channels needs to be determined according to the size of the horizontal ceramic heat conductor. For example, when the size of the horizontal ceramic heat conductor is small, the number of the air flow channels is small to ensure that the air flow passing through the air flow channels can enter the air inlet end and flow out of the air outlet end in a concentrated state.

[0070] Furthermore, there are two air flow channels, and both the air inlet end and the air outlet end of the air flow channel have a long groove structure. The two air flow channels are axially symmetrically distributed with respect to the central axis of the horizontal ceramic heat conductor. In this way, the air flow channel adopting this design can not only better envelop the smoke generated by the mixed e-liquid, but also more fully bring out the smoke, making the aerosol fuller. At the same time, the air flow resistance and the degree of condensation in contact with the e-liquid will also be greatly reduced.

[0071] Further, please also refer to Figure 5 and Figure 6The smoke oil dispersion guide body 44 is also provided with a middle partition 44b, which is located directly above the top surface of the horizontal ceramic heat conductor 10, and there is a gap between the two for accommodating smoke oil; the two air flow channels are also axially symmetrically distributed with the central axis of the middle partition 44b, and two avoidance areas are formed between the middle partition 44b and the inner wall of the smoke oil dispersion guide body 44, and the two avoidance areas are axially symmetrically distributed with the central axis of the middle partition 44b. The avoidance areas are located directly above the air flow channels and are interconnected, and the area of the avoidance areas is larger than the area of the air flow channels. In this way, combined with the above-mentioned smoke oil guide and dispersion structure, the smoke oil can be dispersed more highly and the atomization degree can be higher. More importantly, when the air flow in the concentrated state at the air outlet end of the air flow channel 100 is reduced, the degree of contact with the part of the atomization chamber where smoke oil adheres is reduced. Furthermore, the side of the partition away from the horizontal ceramic heat conductor has an arc-shaped curved surface structure, and the arc-shaped curved surface structure is high in the middle and low at both edges. The side of the partition close to the horizontal ceramic heat conductor has an arc-shaped concave surface design. In this way, the smoke oil can be dispersed more evenly and the degree of aerosol re-condensation is lower.

[0072] In one embodiment, see Figure 11 The horizontal ceramic heat conductor 10 includes a ceramic body 200 and a buckle body 300. The buckle body 300 is arranged on the ceramic body 100, and the gap between the buckle body 300 and the ceramic body 100 is used to form the air flow channel 100. In this way, the buckle body 300 can be tightly buckled with the inner wall of the insulation sleeve, thereby improving the structural reliability and stability.

[0073] Further, please also refer to Figure 10 and Figure 11 The air outlet end of the air flow channel 100 is located between the buckle body 300 and the ceramic main body 100, and the air outlet end of the air flow channel 100 is also located on the top surface of the horizontal ceramic heat conductor 10. The bottom surface of the ceramic main body 200 is provided with a first notch 210, and the side wall of the buckle body 300 is provided with a second notch 310. The first notch 210 and the second notch 310 are connected to each other to form the air inlet end of the air flow channel 100. In this way, through the design of the second notch 310, the contact area between the horizontal ceramic heat conductor 10 and the thermal insulation sleeve can be reduced, which can reduce the powder falling problem during assembly. At the same time, because the buckle body 300 is tightly buckled with the inner wall of the thermal insulation sleeve, the structural reliability and stability are also improved. Secondly, the first notch 210 and the second notch 310 are connected to each other to form the air inlet end of the air flow channel 100, which can make the air intake at the air inlet end 100 more concentrated, the air intake resistance is smaller, and it is more conducive to the airflow to flow out from the air outlet end of the air flow channel in a concentrated state.

[0074] Furthermore, the inner wall of the air flow channel has a stepped structure, so that the air flow flows through the air flow channel in a non-linear state. In this way, the design of the horizontal ceramic heat conductor can be more reasonably optimized and other functions can be enhanced.

[0075] In one embodiment, the horizontal ceramic heat conductor has a rectangular structure or a terraced structure, and the top surface of the horizontal ceramic heat conductor is used to heat the e-liquid.

[0076] Compared with the prior art, the present invention has at least the following advantages:

[0077] For the heat-conducting ceramic body without an air flow channel in the overall structure, since the air flow channel 100 of the horizontal ceramic heat conductor 10 can directly allow the external air flow to enter and flow out in a concentrated state, and the side wall of the horizontal ceramic heat conductor 10 is also completely covered by the heat insulation sleeve, the air flow entering from the outside does not need to flow through the peripheral plastic parts, nor does it need to be provided with an air flow channel on the peripheral plastic parts. The structure is simpler and more compact. The most important thing is that since the external air flow enters and flows out of the air flow channel 100 of the horizontal ceramic heat conductor 10 in a concentrated state, the air intake resistance is reduced. At the same time, the airflow flowing out of the airflow channel 100 in a gathered state is more concentrated, the air intake volume is larger, and the smoke generated by the heated tobacco oil can be quickly entrained. The aerosol formed after mixing rarely contacts the inner wall of the atomization chamber, and the aerosol flows into the inhalation channel and the air nozzle in a more linear direction. In this way, the contact between the aerosol and the tobacco oil on the inner wall of the atomization chamber is greatly reduced, thereby greatly reducing the degree of condensation between the aerosol and the tobacco oil, thereby making the taste of the aerosol inhaled higher and less likely to be lost.

[0078] Secondly, with respect to the vertical thermally conductive ceramic body, the horizontal thermally conductive ceramic body 10 has a flat structure, and the depth to which it needs to be inserted into the thermal insulation sleeve is much smaller than that of the vertical thermally conductive ceramic body. When assembling the vertical thermally conductive ceramic body, the friction between the horizontal thermally conductive ceramic body and the thermal insulation sleeve is smaller, and the insertion stroke is shorter, which can better alleviate the problem of powder falling. Moreover, since the height of the horizontal thermally conductive ceramic body is lower than that of the vertical thermally conductive ceramic body, there is no need to be forced to increase the length of the cartridge.

[0079] Finally, for the horizontal thermally conductive ceramic body with a dispersed airflow outflow design, due to the use of a porous dispersed interval multi-airflow channel design, when the air flows out from the air outlet of each airflow channel, the interaction between the airflows will produce a relatively chaotic gas vortex problem in the atomization chamber, thereby causing the entire airflow system and the subsequently formed aerosol system to greatly increase the degree of contact with the e-liquid adhered to the inner wall of the atomization chamber, thereby aggravating the condensation problem, thereby causing the loss of taste and poor taste restoration. Here, taking the components of the e-liquid as an example, it includes the following compounds: propylene glycol (boiling point 187.3°C), cis-3-hexene-1-ol (boiling point 157°C), n-hexanol (boiling point 157°C), amyl acetate (boiling point 216.4°C), benzoic acid (boiling point 249.2°C), glycerol (boiling point 290°C), saline (boiling point 247°C), ethylene glycol monophenyl propionate (boiling point 288°C), etc. It can be seen from the components and the corresponding boiling points that there are large differences. Therefore, the aerosol with a higher temperature is mixed with the e-liquid with a lower temperature, and the uneven condensation degree of each component is the most critical factor causing the loss of taste. In the horizontal heat-conducting ceramic body 10 of this case, the gas The airflow flowing out of the outlet end of the flow channel 100 in a concentrated state is more concentrated, and the air output is larger and more linear, which can quickly entrain the smoke generated by the heated tobacco oil. The aerosol formed after mixing rarely contacts the inner wall of the atomization chamber, and the aerosol flows into the inhalation channel and the air nozzle in a more linear direction. In this way, the contact between the aerosol and the tobacco oil on the inner wall of the atomization chamber is greatly reduced, thereby greatly reducing the degree of condensation between the aerosol and the tobacco oil, thereby making the taste of the aerosol inhaled higher and less likely to be lost. At the same time, the airflow flowing out in a concentrated state can quickly break through the tobacco oil covering or shielding the air inlet end, thereby making the air intake resistance smaller.
