Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-3, a heating body is applied to a low-temperature heating cigarette appliance and comprises an insulating base body 1 and a supporting guide piece 2, a heating element 3 is arranged on the outer wall of the insulating base body 1, the supporting guide piece 2 is a strip body with a conical top end, a hollow cavity 4 which is penetrated up and down is arranged in the insulating base body 1, the supporting guide piece 2 is fixedly arranged in the hollow cavity 4, the top end is matched and extends out of the insulating base body 1, and the heating body is fixed in the low-temperature heating cigarette appliance (the supporting guide piece is equivalent to a fixing seat of the heating body) through the supporting guide piece 2, so that the heating body can penetrate into tobacco materials 9 when being used conveniently.
In this embodiment, the hollow cavity 4 penetrating up and down is provided in the insulating base 1, and the supporting guide member 2 is fixed in the hollow cavity 4 of the insulating base 1, so that the supporting guide member 2 is not in direct contact with the heating element 3 outside the insulating base 1 when the heating element is assembled, and the heating element with this structure does not damage the heating element 3 when the supporting guide member 2 is assembled compared with the case that the fixing seat is directly arranged outside.
When the heating body with the structure is assembled with the low-temperature heating cigarette appliance, the heating body is fixedly arranged in the appliance through the supporting guide piece 2, and a specific connection mode of the supporting guide piece 2 and the appliance can be a screw connection mode, a plug connection mode or a clamping mode and the like; correspondingly, a connecting screw rod 7 which is in butt joint with the threaded connecting hole is required to be arranged in the matched appliance, and the supporting guide piece 2 is screwed and fixed on the connecting screw rod 7.
In some possible embodiments, the outer walls of the two ends of the insulating base 1 are further provided with connection electrodes 5 for connection to an external power source, the two connection electrodes 5 are respectively connected to the two ends of the heating element 3, and the connection electrode 5 located at the top of the insulating base 1 is electrically connected to the external power source through the support guide 2. In this way, the supporting guide member 2 can reliably fix the heating element in the smoking set and simultaneously can be used as a conductive member for connecting the heating element with a power supply, so that the circuit connection structure is simplified.
It is understood that in practical design, the heating element 3 includes a resistance wire 301 covering the entire outer wall of the insulating base 1 and an insulating layer 302 covering the resistance wire 301, and the end of the resistance wire 301 is exposed from the insulating layer 302 to be connected with the corresponding connection electrode 5; the insulating substrate 1 may be made of an insulating material, or an insulating layer may be provided outside the conductive substrate to form insulation. In this embodiment, the resistance is distributed over the entire area of the insulating base 1, and the connection electrodes 5 are provided at both end portions of the insulating base 1 in such a manner that the temperature distribution of the heating element is uniform throughout; in addition, the welding pad connected with the lead is omitted, so that the resistance values of the heating elements in the same batch tend to be more consistent (the size of the welding pad is not easy to control, and the resistance values of the heating elements are easy to be inconsistent).
Specifically, the insulating base 1 is a tubular thin-walled member with an annular section, the supporting guide member 2 is made of conductive materials, after the supporting guide member 2 is connected with the insulating base 1, the top end of the supporting guide member 2 does not intersect with the space of the insulating base 1, and the rest of the lower part is in a containing relation with the insulating base 1 in the axial direction in space and is fully or partially contacted with the inner wall of the insulating base 1. The inclusion is understood here to mean that the opposite end of the tapered end of the support guide 2 does not spatially protrude beyond one of the end faces of the insulating base 1.
The resistor circuit 301 of the heating element of the present design is printed on the surface of the insulating substrate 1 by thick film printing, and the adopted printed material comprises silver, palladium and other metal paste which can be used for conducting electricity, and the key point of implementation is that the resistor is distributed in the whole area of the insulating substrate 1. In operation with the insertion of an aerosol-generating article, only a portion of the heated region of the insulating substrate 1 is inserted into the aerosol-generating article. The positive and negative electrodes of the resistor of the heating element are respectively positioned at two end surfaces of the tubular heating element, the two ends of the insulating substrate 1 are provided with the tail ends of the resistor printed circuit, the dimension width of the resistor printed circuit is A, B, the resistor printed circuit is respectively annular and one-circle to cover the end surface of the side wall of the insulating substrate 1, a metal paste coverage area is formed between the two resistor printed circuit tail ends in a shape of a Chinese character 'ji', namely, the whole circle of resistor printed circuit at the two ends of the insulating substrate 1 is naturally extended in the metal paste coverage area in the shape of a Chinese character 'ji', namely, the resistor circuit 301 comprises a first section, a second section and a third section which are sequentially connected; the first section and the second section are annularly arranged around the tubular thin-wall piece, and the second section is continuously bent and distributed along the circumferential direction of the tubular thin-wall piece. After the resistor area is printed, an insulating layer is covered on other areas excluding the resistor area 301 extending end A and the resistor area 301 extending end B, and then a ring electrode is printed on the resistor area 301 annular end of the resistor area 301 extending end A and the resistor area 301 extending end B to form two connection electrodes 5 of the heating element.
As shown in fig. 4, when a current passes through a resistor, the temperature is highest because the center of the resistor is the concentration area of the acting force and the reaction force of the current, and the temperature gradually decreases towards the two ends A, B of the resistor because of the lever action, and the longer the length between the end a and the end B is, the larger the temperature difference from the center point is, but as long as the resistor is completely distributed in the region of the resistor, the temperature field is called a temperature field. In the case that the resistances in a section of temperature field are made of the same material for generating the resistances, the meter resistance or the sheet resistance (namely, each meter resistance or each cubic resistance) of the resistances are distributed on the substrate, the width of the local width influences the local temperature difference in the section of temperature field, as shown in fig. 2, the width of a line covered between two ends of the insulating substrate 1 is C, the design preferably adopts the scheme of a=b=c, namely, the temperature difference is not excessively large as a result of different printing widths of the local resistance paste in the section of temperature field as much as possible, but in a specific application scene, the scheme of A, B, C widths can be adopted, but all the requirements are satisfied that the resistance area is covered on the whole substrate, so as to form a section of temperature field.
As shown in fig. 5 and 6, the manufacturing process of the heating element of this embodiment is as follows: the surface of the insulating substrate 1 is covered with a resistor circuit 301, and the tail ends of the resistor are covered to the tail ends of the two ends of the insulating substrate 1; covering an insulating layer on the insulating substrate 1 covered with the resistor circuit 301, wherein the insulating layer avoids extension ends of two ends of the resistor circuit 301 at two ends of the insulating substrate 1; the end extension ends of the two end resistors of the insulating substrate 1 covered with the insulating layer are covered with a paste with as low a meter resistance (sheet resistance) as possible as an electrode. One end of the insulating base 1, which is connected with the supporting guide 2, is provided with more than one through hole 8, a low-meter-resistance (square-resistance) material (conductive matrix) is filled along the hole, a resistance circuit 301 which is connected with the surface of the insulating base 1 is connected with the supporting guide 2, the supporting guide 2 is communicated with the connecting electrode 5 at the top, and the other connecting electrode 5 at the bottom is directly used as an electrode connected with a power supply of an appliance.
As shown in fig. 1, in the above-mentioned temperature field, that is, in the case that the resistor circuit 301 is attached to the surface of the separate insulating substrate 1, the temperatures of the a end and the B end of the insulating substrate 1 tend to be consistent, after the supporting guide 2 is connected, the a end of the insulating substrate 1 absorbs more heat due to the space volume of the supporting guide 2, and the temperature is lower than the temperature of the B end of the insulating substrate 1, but in the application scenario of the design, the cigarettes are inserted from the supporting guide 2 end, the a end is located above, the heat tends to be transferred upward, that is, the a end, and the temperatures of the B end and the a end are reduced. In practical implementation, if it is necessary to further compensate for the temperature difference between the a end and the B end of the insulating substrate 1 caused by the heat absorption of the supporting and guiding member 2, another design scheme as shown in fig. 7 and 8 may be adopted, where the end of the resistor circuit 301 near the supporting and guiding member 2 covers the top surface of the supporting and guiding member 2, so that the conical surface of the supporting and guiding member 2 and the a end of the insulating substrate 1 together form one end of the substrate of the resistor circuit 301; covering the surface of the resistor circuit 301 with an insulating layer, wherein the resistor circuit 301 is prevented from extending to two end regions of the insulating substrate 1 when the insulating layer is covered; the resistor circuit 301 is covered with a conductive material having a small meter resistance or sheet resistance at both end regions extending to the insulating substrate 1. In this solution, the design of the at least one perforation 8 of the end side of the insulating base 1 would be a sufficiently unnecessary condition.
As shown in fig. 9 and 10, in the present embodiment, the surface of the insulating substrate 1 is entirely covered with a section of the resistive wire 301, but each of the corners of the zigzag or the straight shape forming the resistive wire 301 extends to the end of the insulating substrate 1, that is, the resistive wire 301 is continuously bent and distributed along the circumferential direction of the tubular thin-walled member as a whole; when the surface of the resistor circuit 301 is covered with an insulating layer, exposing a micro area at the end of the zigzag or straight resistor circuit 301; then, the two ends of the insulating substrate 1 are covered with a ring-shaped complete low meter resistance or sheet resistance material (forming the connection electrode 5), so that the layer material is communicated with the resistor circuit 301.
Referring to fig. 11, this embodiment also discloses a low-temperature heating cigarette appliance using the above heating element, in which a conductive elastic sheet 6 for butt joint with a connection electrode 5 at the bottom of an insulating substrate 1 is provided, the conductive elastic sheet 6 is provided in plurality, and the plurality of conductive elastic sheets 6 are arranged in a ring shape, thereby forming an annular cavity for inserting the heating element, the connection electrode 5 is provided around the peripheral wall of the insulating substrate 1 in a circle, a connection screw 7 (central electrode) is provided in the middle of the annular cavity, and the connection screw 7 and the conductive elastic sheet 6 are respectively connected with the positive electrode and the negative electrode of a power supply in the appliance.
