[0079] It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and similar expressions used in the present invention are for illustrative purposes only and are not restrictive.

[0080] The utility model discloses an electronic smoking device.

[0081] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0082] like Figure 1 , Figure 2 , Figure 3 As shown, in a preferred embodiment, an electronic smoking device is used to heat an aerosol substrate to generate an aerosol, and the aerosol substrate can be a cigarette 1 in the figure; the electronic smoking device includes: a housing 2, a heating element, an electromagnetic element and an airflow channel 354;

[0083] The housing 2 is provided with a receiving space and a cigarette insertion port, wherein the receiving space is used to receive at least an aerosol matrix, and the cigarette insertion port is used to allow the aerosol matrix to extend into the receiving space;

[0084] The heating element is arranged in the housing 2, and is used to heat the aerosol matrix. The heating element may be in the shape of a tube, a needle or a sheet;

[0085] The electromagnetic element is arranged around the heating element to stimulate the heating element to generate heat. When the heating element generates heat, the aerosol matrix can be heated but not burned. The substances in the aerosol matrix can be converted into smoke for human inhalation.

[0086] The airflow channel 354 is at least partially arranged between the heating element and the electromagnetic element, and is used to allow external air to enter the accommodating space. The airflow channel 354 can connect the air inlet of the electronic cigarette device with the lower end of the aerosol matrix. When the user smokes, the external airflow passes through the air inlet and the airflow channel 354 in sequence and enters the lower end of the aerosol matrix to form a gas flow path. The airflow channel 354 can be heated by the heating element and / or the electromagnetic element. When smoking, the inhaled airflow passes through the airflow channel, so that it can be heated. The heated airflow enters the aerosol matrix, which promotes the smoke generation efficiency of the cigarette.

[0087] The shape of the housing 2 can be cylindrical or prismatic, and a cylindrical space needs to be provided inside for installing various components such as a heating element and an electromagnetic element.

[0088] The electronic cigarette device in this embodiment heats the airflow inhaled by the electronic cigarette device in the airflow channel. Since the airflow is heated by the heat emitted by the high-temperature component in the airflow channel, the smoke generation efficiency of the aerosol matrix is ​​promoted after entering the aerosol matrix, so that the smoke emission efficiency of the first puff is higher, and the amount of smoke in each puff is increased. In addition, the temperature of the surface of the electronic cigarette device can be reduced, and energy recovery is fully utilized to reduce the energy consumption of the electronic cigarette device.

[0089] In one embodiment, if Figure 1 , Figure 3 As shown, the electromagnetic components include:

[0090] The coil support 5, part or all of the heating element is arranged inside the coil support 5, and the air flow channel 354 is arranged between the heating element and the coil support 5;

[0091] The induction coil 6 is sleeved on the coil support 5, and the induction coil 6 can be energized to excite the heating element to generate heat.

[0092] The coil support 5 is a supporting component of the induction coil 6 . The axial length of the coil support 5 is slightly larger than the axial length of the induction coil 6 , and can form a stable support for the induction coil 6 . Figure 3The middle heating element is a heating tube 3, or a heating needle 4 / heating plate 4. Part of the heating tube 3 is arranged inside the coil support 5, and the heating needle 4 / heating plate 4 is arranged inside the coil support 5. It can generate electromagnetic induction with the induction coil 6. When the induction coil 6 is energized, it can excite the heating element to generate heat. The heating principle is: when the induction coil 6 is energized, an alternating magnetic field can be generated, and the heating element generates eddy current in the alternating magnetic field. The heating element is heated by the eddy current to increase its temperature, and the cigarette 1 can be heated without burning to achieve the effect of smoking.

[0093] In one embodiment, if Figure 1 , Figure 2 , Figure 3 As shown, the heating element is tubular, i.e., the heating tube 3 in the figure, and a receiving space for receiving the aerosol matrix is ​​formed in the heating element;

[0094] The air flow channel 354 is arranged between the outer wall of the heating element and the inner wall of the coil support 5 .

[0095] The inner diameter of the heating tube 3 is close to the outer diameter of the cigarette 1 , and the cigarette 1 can be fixed by the heating tube 3 when inserted into the heating tube 3 and will not fall off from the electronic smoking device.

[0096] The airflow channel 354 is arranged between the outer wall of the heating tube 3 and the inner wall of the coil bracket 5. When the induction coil 6 is energized, the heating tube 3 and the coil bracket 5 will both generate heat, which are components with higher temperatures. The airflow channel 354 is also heated. The airflow enters the airflow channel 354, and the airflow channel 354 is heated, thereby being able to heat the airflow.

[0097] In one embodiment, if Figure 1 , Figure 2 , Figure 3 As shown, if the heating tube 3 is not provided but only the heating needle 4 / heating plate 4 is provided, a receiving space for receiving the aerosol matrix is ​​formed in the coil support 5, and the heating element is provided in the receiving space.

[0098] At this time, the inner diameter of the coil support 5 is close to the outer diameter of the cigarette 1, and the cigarette 1 can be fixed by the coil support 5 when inserted into the coil support 5, and will not fall off from the electronic cigarette device. The heating needle 4 / heating plate 4 is arranged inside the coil support 5, and the airflow channel 354 is arranged between the outer wall of the cigarette 1 and the inner wall of the coil support 5. When the induction coil 6 is energized, the heating needle 4 / heating plate 4 and the coil support 5 will heat up, and they are components with higher temperatures, and the airflow channel 354 will also be heated. The airflow enters the airflow channel 354, and the airflow channel 354 is heated, thereby heating the airflow.

[0099] In one embodiment, if Figure 1 , Figure 3As shown, the coil support 5 is tubular, including a side wall 51 and a bottom wall 52 , and the heating element is fixedly connected to the bottom wall 52 of the coil support 5 .

[0100] An opening is provided at the upper end of the side wall 51, and the opening is used to insert the heating tube 3 / hollow tube 3 or cigarette 1. The inner diameter of the opening is not less than the outer diameter of the heating tube 3 / hollow tube 3 or cigarette 1, so as to facilitate the insertion of the heating tube 3 / hollow tube 3 or cigarette 1. The bottom wall 52 is provided at the lower end of the side wall 51, and is arranged opposite to the opening. The side wall 51 and the bottom wall 52 can be made in one piece.

[0101] The bottom wall 52 of the coil support 5 provides an installation base for the heating element. In this case, the heating element is a heating needle 4 / heating plate 4. The lower end of the heating needle 4 / heating plate 4 and the bottom wall 52 of the coil support 5 can be fixedly connected by welding, plugging, clamping, threading or other suitable methods, so that the heating needle 4 / heating plate 4 and the bottom wall 52 of the coil support 5 remain vertical, which is convenient for insertion into the interior of the cigarette 1.

[0102] In one embodiment, a ventilation groove is provided on the inner side of the side wall 51 of the coil support 5 . The ventilation groove extends along the axial direction of the coil support 5 . The ventilation groove is used to enclose the cigarette 1 to form an airflow channel 354 .

[0103] The ventilation groove is a straight groove, which needs to extend from the upper end of the coil support 5 to the lower end of the coil support 5. Because the inner diameter of the coil support 5 is close to the outer diameter of the cigarette 1, the cigarette 1 inserted into the coil support 5 almost occupies the entire internal space of the coil support 5, but will not hinder the ventilation groove set on the side wall 51. The airflow enters the ventilation groove, and the ventilation groove is heated, thereby heating the airflow.

[0104] In one embodiment, if Figure 1 , Figure 2 , Figure 3 As shown, the heating element is needle-shaped or sheet-shaped, that is, the heating needle 4 / heating sheet 4 in the figure, and the heating element can be inserted into the aerosol matrix to connect with the aerosol matrix. When the cigarette 1 is inserted into the heating tube 3 or the coil support 5, the heating needle 4 / heating sheet 4 can gradually insert into the interior of the cigarette 1, and at the same time, it plays a role in fixing the cigarette 1, so that the cigarette 1 will not fall off from the electronic cigarette device.

[0105] The heating needle 4 / heating plate 4 is made of magnetic metal and can be excited by electromagnetic components to generate heat. The heating principle is: the induction coil 6 is energized to generate an alternating magnetic field, and the heating needle 4 / heating plate 4 generates eddy current in the alternating magnetic field. The heating needle 4 / heating plate 4 is heated by the eddy current to increase the temperature, and the cigarette 1 can be heated without burning to achieve the effect of smoking.

[0106] In one embodiment, if Figure 1 , Figure 2 , Figure 3As shown, the electronic cigarette device is provided with a hollow tube 3, which is fixed to the housing 2, and a first opening and a second opening are formed at both ends of the hollow tube 3, the first opening is used for the aerosol matrix to extend into the hollow tube 3, and the heating element extends into the hollow tube 3 through the second opening. The hollow tube 3 is used to fix the cigarette 1, and the hollow tube 3 may not have a heating function and is not used to heat the cigarette 1.

[0107] The first opening is provided at the upper end of the hollow tube 3, and the first opening is spaced a preset distance from the cigarette insertion port. The inner diameter of the first opening is not less than the outer diameter of the cigarette 1, so that the cigarette 1 can smoothly enter and exit the hollow tube 3. The cigarette 1 passes through the cigarette insertion port and the first opening in sequence and extends into the hollow tube 3. The second opening is provided at the lower end of the hollow tube 3, and the area of ​​the second opening is smaller, so as to fit the heating needle 4 / heating plate 4. The hollow tube 3 can be fixedly connected to the side wall of the shell 2 through a connecting arm, so as to realize the installation and fixation of the hollow tube 3 in the shell 2. The connecting arm radially extends from the side wall of the hollow tube 3, and can contact the side wall of the shell 2 to realize the fixed connection.

The hollow tube 3 is used to fix the cigarette 1, and the hollow tube 3 may not have a heating function and is not used to heat the cigarette 1.

[0109] That is, the first opening at the upper end of the hollow tube 3 directly forms a cigarette insertion port, and the cigarette 1 can directly enter and exit the hollow tube 3 from the cigarette insertion port. The inner diameter of the cigarette insertion port is not less than the outer diameter of the cigarette 1, so that the cigarette 1 can smoothly enter and exit the hollow tube 3. The second opening is set at the lower end of the hollow tube 3, and the area of ​​the second opening is smaller, which is suitable for the heating needle 4 / heating plate 4. The upper end of the hollow tube 3 can be fixedly connected to the top of the shell 2 to achieve the installation and fixation of the hollow tube 3 in the shell 2.
