Detailed Description
In order to more clearly explain the overall concept of the present application, the following detailed description is given by way of example in conjunction with the accompanying drawings.
In this application, it is to be understood that terms such as "including" or "having" are intended to indicate the presence of the disclosed features, numbers, steps, acts, components, parts, or combinations thereof, and are not intended to preclude the presence or addition of one or more other features, numbers, steps, acts, components, parts, or combinations thereof.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1 and 2, an embodiment of the present application provides a heater including: the heating device comprises a first base 1 and a heating structure 2 fixed on the upper surface of the first base 1, wherein the heating structure 2 and the first base 1 are enclosed to form a hollow structure; the heat generating structure 2 includes a heat conducting layer 21, an insulating layer 22 located inside the heat conducting layer 21, and an electrically conductive heat generating body 23 on the inner surface of the insulating layer 22; the conductive heating element 23 is electrically connected to the electrode structure 1a penetrating the first base 1.
The insulating layer 22 wraps the conductive heating element 23, so that insulation between the conductive heating element 23 and the outside and first protection of the conductive heating element 23 are realized. Meanwhile, the insulating layer 22 should have good thermal conductivity so as to rapidly dissipate heat generated from the conductive heat generating body 23. To this end, alternative materials for the insulating layer 22 include: at least one of glass, ceramic, filled heat conducting polymer material or quartz.
The heat conductive layer 21 is located outside the insulating layer 22 and should have a better thermal conductivity than the insulating layer 22 to dissipate heat more quickly. At the same time, the structure of the heat conducting layer 21 should be strong so as to provide further mechanical protection for the insulating layer 22 and the electric heat generating body 23 in the heat conducting layer 21. For this purpose, the material of the heat conductive layer 21 may be selected from metals or alloys.
The conductive heating element 23 should be easily formed on the inner surface of the insulating layer 22. For this reason, the optional materials of the conductive heating body 23 include: at least one of a metal, an alloy, a carbide, a nitride, molybdenum disilicide, and a heat-generating metal paste.
If the heater is applied to heating a non-combustion smoking set, the driving circuit supplies driving power to the conductive heating element 23 through the electrode structure 1 a.
Since the insulating layer 22 and the heat conductive layer 21 provide a double mechanical protection to the electrically conductive heat generating body 23, the mechanical stability of the heat generating body is better.
The base portion (including the first base 1 and a second base described later) is required to have a good heat insulating property, and this portion is required to block heat inside the heater and prevent the heat from being radiated from below. The base part can be matched with the internal structure of the heating appliance, thereby achieving the purpose of fixing the heater. Of course, the portion of the base portion in contact with the heat conductive layer 21 should be sealed to prevent the ingress of smoke into the interior of the heater.
Correspondingly, according to the current view of fig. 1, the lower surface of the base is inlaid with positive and negative electrodes (i.e., two electrode structures 1a in fig. 1 and 2), one ends of the insides of the positive and negative electrodes are connected to two ends of the conductive heating body 23 inside the heater, and the external ends of the positive and negative electrodes are connected to the driving circuit. The positive electrode and the negative electrode can be in the form of sockets, also can be in the form of a thimble connector, or directly adopts the form of two leads.
Referring to fig. 3, the conductive heating element 23 is in a screw shape. Referring to fig. 4, the conductive heating element 23 is spread to a plane and then is bent in an opening direction alternately toward the first base 1 and away from the first base 1. Of course, the conductive heating element 23 may be formed in a U shape with its opening facing the first base 1. Those skilled in the art can flexibly set the shape of the conductive heating element 23 according to actual needs.
Note that in order to attach the conductive heating element 23 to the inner surface of the insulating layer 22, a certain space is surrounded by the inner surface of the insulating layer 22. After the conductive heating element 23 is attached, a certain space is left. The space may be used to house a temperature sensing element. The temperature measuring element is close to the conductive heating element 23, and can accurately measure the temperature of the conductive heating element 23. The temperature of the conductive heating element 23 is grasped, and the temperature of the conductive heating element 23 can be controlled more accurately. Even if the deviation of the resistance temperature coefficient of the conductive heating element 23 is large, the output power of the driving circuit can be adjusted more accurately, so that the temperature of the conductive heating element 23 can be controlled to a desired temperature. The deviation of the heating property of the conductive heating element 23 is avoided to cause the deviation of the heating property of the final heating non-combustible cigarette, and the consistency of the mouth feel of the smoke generated by the final tobacco is also ensured.
One implementation of placing a temperature sensing element in the hollow region 100 is as follows.
Referring to fig. 5 and 6, the first base 1 is provided with a temperature measuring insertion hole 1b, and the temperature measuring insertion hole 1b is opposite to the hollow area 100. The temperature measuring jack 1b is a through hole.
In conjunction with this, the heater further comprises a second base and a temperature measuring element fixed on the second base, the temperature measuring element is located in the hollow area 100, the second base is fixed in the temperature measuring insertion hole 1b, and the temperature measuring element is electrically connected with the electrode structure 1a penetrating through the second base.
In use, the temperature measuring element is inserted into the hollow area 100 defined by the first base 1 and the heat generating structure 2 from the temperature measuring insertion hole 1b, and then the second base and the first base 1 are fixed together (for example, by means of adhesion or extrusion). Thereby resulting in a closed hollow region 100. The heat is prevented from damaging the driving circuit around the first base 1.
Another implementation of placing a temperature sensing element in the hollow region 100 is as follows.
The heater also includes a temperature sensing element located within the hollow region 100, the temperature sensing element being electrically connected to the electrode structure penetrating the first base 1.
The difference from the foregoing implementation is that the first base 1 does not have the temperature measuring insertion hole 1 b. The electrode structure connected to the temperature measuring element and the electrode structure 1a connected to the conductive heating element 23 are connected to an external driving circuit through the electrode structure 1a penetrating the first substrate. Of course, the drive circuitry should be capable of reading the electrical signal generated by the temperature sensing element.
Optionally, the temperature sensing element comprises a thermocouple or a thermal resistor or a thermistor.
If the heater is to be used in heating non-burning smoking articles, the heating structure 2 should be shaped to fit within the tobacco. Based on this, the outer surface of the heat generating structure 2 is in the shape of a needle, a sheet, a column, or a column with a chamfered top portion extending in a direction away from the upper surface. For example, the outer side surface of the heating element is columnar, and the cross section of the heating element can be circular, polygonal and other shapes.
Embodiments of the present application also provide a heated non-burning smoking article comprising the aforementioned heater. The heating and non-combustion device may further include a drive circuit connected to the heater, a battery, and a casing.
In this heating non-burning smoking set, the stability of heater is higher. In some alternative embodiments, the heating non-combustion smoking set may precisely control the temperature of the conductive heating body. Thereby providing a more stable taste experience for the user.
The embodiments in the present application are described in a progressive manner, and the same and similar parts among the embodiments can be referred to each other, and each embodiment focuses on the differences from the other embodiments.
The above are merely examples of the present application and are not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
