[0031] In the above-mentioned atomizer, since the conductive graphene coating is formed at least on the abutment portion, the heating portion and the inner wall of the vent hole, respectively, the conductive rod abuts against the conductive graphene coating at a position corresponding to the abutment portion, so that the conductive rod is electrically connected to the conductive graphene coating. Since the conductive graphene coating itself has good electrical and thermal conductivity, the heat of the conductive graphene coating can be better exchanged with the airflow passing through the vent hole to generate a hot airflow that directly contacts and heats the cigarette. At the same time, the conductive graphene coating at a position corresponding to the heating portion can conduct heat to the surface of the cigarette to heat and atomize the cigarette. Since the conductive graphene coating can achieve uniform heat generation when conducting electricity, and the inner wall of the vent hole is coated with the conductive graphene coating, the airflow passing through the vent hole can be reliably heated. , that is, the air flow is reliably heated, avoiding the problem of uneven heating in traditional heating through heating wires, and the hot air flow is output by heating. The hot air flow contacts and acts on the surface of the cigarette to achieve uniform heating of the cigarette surface, that is, the cigarette is heated by the thermal radiation and thermal convection principles of the hot air flow, which greatly improves the utilization efficiency of thermal energy and reduces the energy consumption of the electronic atomization device; since the conductive graphene coating itself has good conductivity, the conductive rod is abutted against the conductive graphene coating, so that the conductive rod is electrically connected to the conductive graphene coating, and there is no need to add conductive pins, avoiding the problem of low installation difficulty of the heating element; in addition, the conductive graphene coating has good antibacterial properties and is not easy to oxidize, making the use of the atomizer safer and more hygienic.

[0032] like Figure 1 and Figure 2 As shown, an atomizer 100 of an embodiment includes a substrate 110, a conductive graphene coating 120 and a conductive rod 130. The substrate 110 is provided with an abutting portion 112 and a heating portion 114. The substrate 110 is formed with a vent 111, and the vent 111 extends to the surface of the abutting portion 112 and the heating portion 114 respectively, so that the airflow on one side of the abutting portion 112 flows to the heating portion 114 through the vent 111. The conductive graphene coating 120 is at least formed on the inner wall of the abutting portion 112, the heating portion 114 and the vent 111 respectively. The conductive graphene coating 120 is used to abut against a cigarette at a position corresponding to the heating portion 114, so that the heat generated by the conductive graphene coating 120 being energized can be conducted to the cigarette for heating and atomization. The conductive rod 130 abuts against the conductive graphene coating 120 at a position corresponding to the abutting portion 112 , so that the conductive graphene coating 120 conducts electricity through the conductive rod 130 .

[0033] See also Figure 3In this embodiment, the abutment portion 112 and the heating portion 114 are respectively arranged at the two end positions of the substrate 110. Specifically, the abutment portion 112 is arranged on one side of the air inlet end of the substrate 110, and the heating portion 114 is arranged on one side of the air outlet end of the substrate 110. It can be understood that in other embodiments, the abutment portion 112 is not limited to being arranged on one side of the air inlet end of the substrate 110, and the heating portion 114 is not limited to being arranged on one side of the air outlet end of the substrate 110. In one embodiment, the abutment portion 112 can also be arranged on the side wall of the substrate 110 or at a position deviated from the air inlet end of the substrate 110. In one embodiment, the heating portion 114 can also be arranged at a position deviated from the air outlet end of the substrate 110.

[0034] In the above-mentioned atomizer 100, since the conductive graphene coating 120 is at least formed on the inner wall of the abutting portion 112, the heating portion 114 and the vent hole 111 respectively, the conductive rod 130 abuts against the conductive graphene coating 120 at a position corresponding to the abutting portion 112, so that the conductive rod 130 is electrically connected to the conductive graphene coating 120. Since the conductive graphene coating 120 itself has good electrical and thermal conductivity, the heat of the conductive graphene coating 120 is better exchanged with the airflow passing through the vent hole 111, generating a hot airflow that directly contacts and heats the cigarette. At the same time, the conductive graphene coating 120 at a position corresponding to the heating portion 114 The heat can be transferred to the surface of the cigarette to heat and atomize the cigarette. Since the conductive graphene coating 120 can achieve uniform heating when conducting electricity, and the inner wall of the vent is coated with the conductive graphene coating 120, the airflow passing through the vent is reliably heated, that is, the airflow is reliably heated, avoiding the problem of uneven heating in the traditional heating wire, and outputting hot air flow to heat the surface of the cigarette, and the hot air flow contacts and acts on the surface of the cigarette to achieve uniform heating of the surface of the cigarette, that is, the heat radiation and thermal convection principle of the hot air flow are used to heat the cigarette, which greatly improves the utilization efficiency of thermal energy and reduces the energy consumption of the electronic atomization device. Since the conductive graphene coating 120 itself has good conductivity, the conductive rod 130 is in contact with the conductive graphene coating 120, so that the conductive rod 130 is electrically connected to the conductive graphene coating 120, and there is no need to add conductive pins, which avoids the problem of low installation difficulty of the heating element. In addition, the conductive graphene coating 120 has good antibacterial properties and is not easy to oxidize, making the use of the atomizer 100 safer and more hygienic.

[0035] Further, the conductive graphene coating 120 is at least formed on the inner walls of the abutting portion 112, the heating portion 114 and the vent 111, that is, the conductive graphene coating 120 is at least formed on the inner walls of the abutting portion 112, the heating portion 114 and the vent 111 by a printing process. In this embodiment, the conductive graphene coating 120 is formed on the inner walls of the abutting portion 112, the heating portion 114 and the vent 111. It can be understood that in other embodiments, the conductive graphene coating 120 can also be formed on the outer wall of the substrate 110.

[0036] It should be noted that the conductive graphene coating 120 is a coating structure containing water-based graphene electrothermal ink. The so-called water-based graphene electrothermal ink is a new type of electrothermal ink with water as solvent, water-based resin as connector, and graphene as heating body. It has extremely low pressing power change rate and excellent electrothermal power stability, so that the conductive graphene coating 120 has good heating performance and conductivity. Furthermore, the electrothermal ink can be made into a far-infrared graphene electrothermal film through full-printing printing technology, which has a higher thermal conversion rate, faster heating speed and stronger far-infrared radiation than the traditional ink slurry made by adding carbon powder, and has the characteristics of good printing adaptability, high production efficiency, safety and environmental protection, and wide application.

[0037] In order to make the substrate 110 have better thermal conductivity, in one embodiment, the substrate 110 is a thermally conductive ceramic, so that the substrate 110 has better thermal conductivity. In this way, the heat generated by the conductive graphene coating 120 can be conducted through the substrate 110, so that the substrate 110 and the conductive graphene coating 120 can both contact and heat the cigarette, especially at the contact portion between the substrate 110 and the cigarette, the heat on the substrate 110 can directly act on the cigarette, and at the same time, the conductive graphene coating 120 can be better formed on the substrate 110.

[0038] like Figure 3 and Figure 4 As shown, in one embodiment, the atomizer 100 further includes a heat-insulating sleeve 140, the heat-insulating sleeve 140 is formed with a plug hole 142 connected to the vent hole, the heating portion 114 is arranged corresponding to the position of the conductive graphene coating 120 and the plug hole 142, and the heat-insulating sleeve 140 is sleeved on the substrate 110, so that the heat-insulating sleeve 140 can better insulate the heat of the substrate 110 and reduce the heat loss of the substrate 110.

[0039] like Figure 2As shown, in one embodiment, the heating portion 114 is formed with an abutment groove 114a at a position corresponding to the conductive graphene coating 120, that is, the conductive graphene coating 120 is formed in the abutment groove 114a, and the abutment groove 114a is connected to the plug hole 142. The abutment groove 114a is used to abut against the cigarette, so that the atomizer 100 can better heat and abut against the cigarette, and at the same time, the conductive graphene coating 120 can be better formed on the heating portion 114.

[0040] like Figure 6 As shown, in one embodiment, the heat insulating sleeve 140 is further formed with a limiting groove 144 communicating with the plug hole 142, and the plug hole 142 is communicated with the vent hole through the limiting groove 144. The base 110 is located in the limiting groove 144, and the diameter of the base 110 is larger than the inner diameter of the plug hole 142, so as to prevent the base 110 from sliding into the plug hole 142, so that the base 110 can be better accommodated and limited in the limiting groove 144.

[0041] like Figure 2 and Figure 3 As shown, in one embodiment, a limiting step 116 is formed on the outer peripheral wall of the base 110 adjacent to the end of the conductive rod 130, the diameter of the limiting step 116 is larger than the inner diameter of the limiting groove 144, and the limiting step 116 abuts against the thermal insulation sleeve 140 to prevent the limiting step 116 from sliding into the limiting groove 144, while playing a better limiting role. In this embodiment, the limiting step 116 is arranged around the outer peripheral wall of the base 110.

[0042] In one of the embodiments, an air intake gap is formed between the heat insulation sleeve 140 and the base body 110, and the air intake gap is connected with the plug hole 142, so that the plug hole 142 is connected with the ventilation hole and the air intake gap respectively, so that the airflow can not only enter the plug hole 142 through the ventilation hole to heat the bottom of the cigarette, but also enter the plug hole 142 through the air intake gap to heat the side wall of the cigarette, so that the atomizer 100 can better heat and atomize the cigarette.

[0043] like Figure 3 and Figure 4 As shown, further, an air intake groove 116a connected to the air intake gap is provided on the limiting step 116, so that the airflow on the side of the base 110 where the abutment portion 112 is provided enters the air intake gap through the air intake groove 116a, and then enters the plug-in hole 142 from the air intake gap, so that part of the airflow can better heat and atomize the cigarette through the air intake gap.

[0044] In one embodiment, the conductive rod 130 elastically abuts against the conductive graphene coating 120, so that the conductive rod 130 is electrically connected to the conductive graphene coating 120. In this embodiment, the conductive rod 130 is a conductive spring pin, so that the conductive rod 130 elastically abuts against the conductive graphene coating 120. In other embodiments, the conductive rod 130 can also be other conductive rod-shaped structures.

[0045] like Figure 3 and Figure 4 As shown, in one embodiment, a positioning groove 112b is provided at a position of the abutting portion 112 corresponding to the conductive graphene coating 120, and the conductive rod 130 abuts against the inner wall of the positioning groove 112b. When the conductive rod 130 abuts against the conductive graphene coating 120 at a position corresponding to the abutting portion 112, it is not easy to slide off the abutting portion 112, so that the conductive rod 130 abuts against the conductive graphene coating 120 at a position corresponding to the abutting portion 112. Furthermore, the positioning groove 112b is communicated with the air intake groove 116a, so that the airflow enters the air intake gap through the conductive rod 130 abutting against the inner wall of the positioning groove 112b, making the overall structure of the atomizer 100 more compact. In addition, since the positioning groove 112b is connected to the air inlet groove 116a, the airflow ventilates and dissipates heat at the abutment position between the conductive rod 130 and the conductive graphene coating 120, avoiding overheating at the abutment position between the conductive rod 130 and the conductive graphene coating 120, thereby improving the electrical performance of the atomizer 100.

[0046] like Figure 3 and Figure 4 As shown, in order to make the airflow passing through the base 110 heat and atomize the cigarette better, further, there are multiple ventilation holes 111, and the multiple ventilation holes are arranged side by side, and each ventilation hole extends to the surface of the abutment portion 112 and the heating portion 114 respectively, so that the airflow passing through the base 110 heats and atomizes the cigarette better.

The support base 150 is provided with a negative pressure hole 152 connected to the ventilation groove 113, and the negative pressure hole 152 is connected to the peripheral air, so that the peripheral air enters the vent through the negative pressure hole 152 and the ventilation groove 113 to heat the airflow. In this embodiment, the ventilation groove 113 is connected to the positioning groove 112b and the air intake groove 116a respectively. When the user inhales, the airflow of the ventilation groove 113 can also enter the air intake gap through the positioning groove 112b or the air intake groove 116a, so that the airflow can ventilate and dissipate the heat of the abutting position between the conductive rod 130 and the conductive graphene coating 120, so that the airflow can be heated and the abutting position between the conductive rod 130 and the conductive graphene coating 120 can be better ventilated and dissipated.

The atomizer 100 also includes a mark switch 160, which is located in the groove 156 and blocks the trigger air hole 153. When the user inhales, the airflow in the negative pressure hole is ventilated and heat-dissipated to the abutting position of the conductive rod 130 and the conductive graphene coating 120 through the ventilation groove 113 and the positioning groove in turn. At the same time, the airflow in the negative pressure hole can also pass through the base 110 through the ventilation groove 113 and the vent hole 111. Since the cross-sectional area of ​​the triggering air hole 153 is smaller than the cross-sectional area of ​​the negative pressure hole 152, and the triggering air hole is connected to the negative pressure hole, negative pressure is generated in the negative pressure hole 152 and the triggering air hole to trigger the mark switch 160. The mark switch 160 is electrically connected to the conductive rod 130, so that the mark switch can control the on and off of the conductive rod 130, and then control the switch of the atomizer 100.

In addition, since the conductive graphene coating 120 itself has good electrical and thermal conductivity, the heat of the conductive graphene coating 120 is better exchanged with the airflow passing through the vent hole 111, generating a hot airflow that directly contacts and heats the cigarette. At the same time, the conductive graphene coating 120 at a position corresponding to the heating portion 114 can conduct heat to the surface of the cigarette to heat and atomize the cigarette.

Specifically, the air inlet chamber 210 is connected to the vent hole through the trigger air hole 153, the negative pressure hole 152, and the air inlet groove 116a in sequence.

[0057] like Figure 1 and Figure 6As shown, further, the electronic atomization device 10 also includes a shell cover 300, which is covered on the shell 200.

The plug hole 142 is connected to the air outlet, and the cigarette can be inserted into the plug hole 142 through the air outlet, so that the conductive graphene coating 120 on the substrate 110 can heat the cigarette. In this embodiment, the heat insulation sleeve 140 and the shell cover 300 are integrally formed, so that the structure of the electronic atomization device 10 is more compact, and the heat insulation sleeve 140 and the shell cover 300 are firmly connected. In other embodiments, the heat insulation sleeve 140 and the shell cover 300 can also be formed separately and connected by gluing or welding.

[0059] like Figure 1 and Figure 6 As shown, further, the electronic atomization device 10 also includes a battery 400, a battery cavity 220 is formed in the shell 200, the battery cavity is separated from the air inlet cavity 210, the battery is arranged in the battery cavity, and the battery is electrically connected to the conductive rod, so that the battery is electrically connected to the conductive graphene coating through the conductive rod.

[0060] like Figure 1 and Figure 6 As shown, the electronic atomization device 10 further includes a USB charging plug 500, which is arranged on the housing 200 and electrically connected to the battery 400.

[0062] In the above-mentioned atomizer 100, since the conductive graphene coating 120 is at least formed on the inner wall of the abutting portion 112, the heating portion 114 and the vent hole 111 respectively, the conductive rod 130 abuts against the conductive graphene coating 120 at a position corresponding to the abutting portion 112, so that the conductive rod 130 is electrically connected to the conductive graphene coating 120. Since the conductive graphene coating 120 itself has good electrical and thermal conductivity, the heat of the conductive graphene coating 120 is better exchanged with the airflow passing through the vent hole 111, generating a hot airflow that directly contacts and heats the cigarette. At the same time, the conductive graphene coating 120 at a position corresponding to the heating portion 114 The heat can be transferred to the surface of the cigarette to heat and atomize the cigarette. Since the conductive graphene coating 120 can achieve uniform heating when conducting electricity, and the inner wall of the vent is coated with the conductive graphene coating 120, the airflow passing through the vent is reliably heated, that is, the airflow is reliably heated, avoiding the problem of uneven heating in the traditional heating wire, and outputting hot air flow to heat the surface of the cigarette, and the hot air flow contacts and acts on the surface of the cigarette to achieve uniform heating of the surface of the cigarette, that is, the heat radiation and thermal convection principle of the hot air flow are used to heat the cigarette, which greatly improves the utilization efficiency of thermal energy and reduces the energy consumption of the electronic atomization device. Since the conductive graphene coating 120 itself has good conductivity, the conductive rod 130 is in contact with the conductive graphene coating 120, so that the conductive rod 130 is electrically connected to the conductive graphene coating 120, and there is no need to add conductive pins, which avoids the problem of low installation difficulty of the heating element; in addition, the conductive graphene coating 120 has good antibacterial properties and is not easy to oxidize, making the use of the atomizer 100 safer and more hygienic.
