Detailed Description
The technical solution in the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It should be apparent that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments in the present application, are within the scope of protection of the present application.
Referring to fig. 1 and 2, an electronic cigarette heating element 100 according to an embodiment of the present invention includes a heating portion 10, a heat conducting portion 20, and an insulating portion 30. The heat conduction portion 20 includes a body 201 and a plurality of protrusions 202 provided on an outer peripheral surface of the body 201. A recess 20a is cut into the body 201. In one embodiment, the groove 20a is disposed about a central axis of the body 201. The heat generating portion 10 is disposed in the recess 20 a. The shape of the groove 20a may match the shape of the heat generating part 10, so that the heat generating part 10 may be closely attached to the inner wall of the heat conducting part 20, and heat conduction is fast and uniform. The insulating portion 30 is disposed on the heat generating portion 10 and disposed in the recess 20a together with the heat generating portion 10. The insulating part 30 serves to prevent the heating part 10 from being short-circuited.
A sealing portion (not shown) for sealing the electronic cigarette heating element 100 is also provided at the opening of the recessed groove 20 a. The sealing part can effectively prevent the performance change caused by the change of resistance value due to the aging of the heating part 10, and the consistency of the use feeling of the electronic cigarette is kept. Meanwhile, the peculiar smell emitted by the heating part 10 at high temperature can be prevented, and the smoking taste is improved. The sealing portion may include a high temperature resistant ceramic paste. The sealing portion may be formed by applying a high temperature resistant ceramic paste to an opening of the groove 20a and curing the same.
The heat generating portion 10 may be a metal heating wire, such as a resistance wire made of nickel wire or other alloy. The heat generating portion 10 may be formed in a spiral shape. The heat generating portion 10 includes a main shaft 101 and a spiral portion 102 surrounding the main shaft 101. The main shaft 101 is connected to the screw 102. The end of the spindle 101 and the spiral part 102 on the same side may be used for connection to a power supply, generating heat at the voltage supplied by the power supply.
The heat conduction portion 20 serves to conduct heat emitted from the heat generating portion 10 to the air. The air may be heated prior to heating the tobacco rod. The heat conduction portion 20 may be made of a ceramic material. The ceramic material is, for example, zirconia ceramic or alumina ceramic. The mass fraction of the main body material of the ceramic material is 75-99%. The main component of the ceramic material is the component with the highest mass fraction. For example, the main material of zirconia ceramics is zirconia, and the main material of alumina ceramics is alumina. When the heat conducting portion 20 is made of alumina ceramic, the alumina ceramic has an alumina mass fraction of 75% to 99%. The material has light weight, small relative heat capacity, less heat storage and high heat conductivity.
The plurality of protrusions 202 may be uniformly distributed on the outer circumferential surface of the body 201, or may be irregularly or randomly distributed on the outer circumferential surface of the body 201. The plurality of protrusions 202 form air passages therebetween. The air passage allows sufficient space and time for the air to exchange heat with the heat conducting portion 20 as it flows through the heat conducting portion 20, ensuring that the air has a sufficiently high temperature when entering the cigarettes.
Referring to fig. 3 and 4, in one embodiment, the body 201 of the heat conduction portion 20 is formed in a cylindrical shape. It is understood that the body 201 may also be formed in a prismatic or other shape. A plurality of projections 202 are spaced apart from one another along the perimeter of the body 20. Also, each protrusion 202 extends from one end to the other end in the length direction of the body 201. It is understood that the greater the number of the protrusions 202, the greater the heat exchange area of the air with the heat conduction portion 20, and the more advantageous the air temperature is to be raised quickly. The shape, number and size of the protrusions are not limited in this application. For example, the cross-section of the protrusion may be trapezoidal, rectangular, triangular, semi-circular, etc. The number of protrusions 202 may be, for example, 6-10. The height of the heat conducting portion may be 9-12 mm.
Referring to fig. 5, in another embodiment, the heat conduction portion 20 includes a heat exchange area 21 and an air flow area 22. The heat exchange area 21 and the air flow area 22 are disposed spaced apart from each other. A plurality of projections 202 are located in the heat exchange area 21 and are spaced apart from one another along the perimeter of the body 20. For example, the heat exchange area 21 comprises two ends of the heat conduction portion 20, and the air flow area 22 is located between the two ends and is composed of the body 201. The present application does not limit the location and number of the heat exchange area 21 and the air flow area 22. As long as a space in which air flows freely is reserved in the heat conduction portion 20. The design in which the heat exchange area 21 and the air flow area 22 are spaced apart from each other can reduce the volume and weight, and the air flows more freely on the surface of the heat conductive portion 10, facilitating uniform heating.
In another embodiment, a plurality of protrusions 202 may be spaced apart from each other along the length of the body 201. For example, as shown in fig. 6, the plurality of protrusions 202 may be connected end to end, formed in a spiral shape, and spaced apart from each other along the length direction of the body 201. The plurality of protrusions 202 form air passages therebetween for heat exchange with air.
The insulating portion 30 may be made of a ceramic material. The ceramic material is, for example, zirconia ceramic or alumina ceramic. The insulation part 30 may insulate different portions of the heat generating part from each other. The insulating part 30 is fitted over the main shaft 101 to insulate the main shaft 101 from the spiral part 102, thereby preventing the short circuit of the heat generating part 10.
In another embodiment of the present application, the electronic cigarette heating element 100 may further include a temperature sensing element, and the temperature sensing element is connected to the heat conducting portion 20. The temperature sensing element may be one or more of a thermocouple, an NTC thermistor or a temperature sensor.
When the electronic cigarette heating body 100 starts to work, the heating part 10 heats and conducts heat to the heat conducting part 20, air exchanges heat with the heat conducting part 20 through the heat conducting part 20, and the air contacts with cigarettes after the temperature rises to heat the cigarettes for being sucked by a user.
In addition, please refer to fig. 7, the present application further provides an electronic cigarette 1 for heating a cigarette 2. The electronic cigarette 1 includes an electronic cigarette heating element 100, a cup 200, and a control unit 30. The electronic cigarette heater 100 has one end connected to the cup 200 and the other end connected to the control unit 30. The cup 200 is intended for the insertion of the rod 2. The control unit 30 includes a power supply, a circuit board, and the like.
In the electronic cigarette heating element 100 and the electronic cigarette 1 of the present application, the plurality of protrusions 202 are provided in the heat conduction portion 20, and an air passage is formed between the plurality of protrusions 202. The air passage allows sufficient space and time for the air to exchange heat with the heat conducting portion 20 as it flows through the heat conducting portion 20, ensuring that the air has a sufficiently high temperature when entering the cigarettes.
