Detailed Description
An example of the heater 10 will be described below with reference to the drawings. As shown in fig. 1, a heater 10 of the present disclosure has a 1 st member 1, a heat generating resistor 2, and a 2 nd member 3.
The 1 st member 1 is a member for protecting the heating resistor 2. The 1 st member 1 is a rod-like member. Here, the rod-shaped member means a member having a longitudinal direction, and the 1 st member 1 may be a plate-shaped or columnar member or a tubular member. The 1 st component 1 comprises an insulating material and may also comprise a ceramic material, for example.
Regarding the dimension of the 1 st member 1, for example, when the 1 st member 1 is plate-shaped, when the main surface is rectangular, the length of the long side can be set to 5 to 20mm, the length of the short side can be set to 1 to 10mm, and the thickness can be set to 0.08 to 1 mm. Further, the front end of the 1 st member 1 may also be tapered so that an object to be heated is easily inserted into the end portion. Further, the front end or the whole of the 1 st member 1 may also be warped.
In addition, when the 1 st member 1 is a tubular member, the length in the longitudinal direction can be set to 5 to 20mm, the inner diameter can be set to 8 to 20mm, and the outer diameter can be set to 8.5 to 22 mm.
The heating resistor 2 is a member for heating an object to be heated. The heating resistor 2 can be provided on the surface or inside the 1 st member 1, for example. The heating resistor 2 may be a linear or belt-shaped member, for example. The heating resistor 2 may have a folded portion, for example. The heating resistor 2 may be electrically connected to an external power supply. The heating resistor 2 can generate heat by applying a current thereto, and heat an object to be heated. The heating resistor 2 may be provided along the longitudinal direction of the 1 st member 1.
The heating resistor 2 includes, for example, tungsten, molybdenum, chromium, carbide thereof, or metal such as gold, silver, palladium, or platinum. The heating resistor 2 may have alumina, silicon nitride, or the like as a component other than metal. The heating resistor 2 has, for example, a length of 5 to 50mm, a width of 0.2 to 2mm, and a thickness of 0.005 to 0.1 mm.
The heating resistor 2 may be provided from the front end to the rear end of the 1 st member 1. As shown in fig. 13 and 14, the heating resistor 2 may be connected to the lead portion 5 and the lead wire 7. In this case, the resistance value of the lead portion 5 can be made smaller than that of the heating resistor 2. This can reduce heat generation in the lead portion 5.
As shown in fig. 1, the heater 10 of the present disclosure has a 2 nd member 3 joined to an end surface of a 1 st member 1 and having a lower thermal conductivity than the 1 st member 1. This can reduce the temperature of the tip of the heater 10 and protect the end face of the 1 st member 1 by the 2 nd member 3. As a result, when the heater 10 is stuck into the object to be heated, the heater 10 can be improved in durability while reducing the risk of high temperature at the depth of the object to be heated.
The strength of the tip of the heater 10 can be improved by joining the 2 nd member 3 to the end face of the 1 st member 1. The 2 nd member 3 may have, for example, a plate shape, a cone shape, a truncated cone shape, or a cylindrical shape, or may have a combination of these shapes. In the example shown in fig. 1, the 2 nd member 3 is cylindrical. The 2 nd member 3 may be, for example, a ceramic member such as zirconia or alumina. As an example of the 2 nd member 3 having a lower thermal conductivity than the 1 st member 1, for example, when the 1 st member 1 is alumina, the 2 nd member 3 can be made of zirconia, and when the 1 st member 1 is aluminum nitride, the 2 nd member 3 can be made of silicon nitride.
Further, the 1 st member 1 may have alumina, and the 2 nd member 3 may have zirconia. Thus, since the 2 nd member 3 at the tip of the heater 10 is a member having high elasticity, when the heater 10 pierces the object to be heated, the possibility of breakage of the 2 nd member 3 can be reduced.
Further, as shown in fig. 2, the 2 nd member 3 may have a shape tapered toward the front end. This makes it possible to easily pierce the heating target into the distal end of the heater 10. In the example shown in fig. 2, the 2 nd member 3 is conical.
Further, as shown in fig. 3, the 2 nd member 3 may be a shape in which a cylindrical portion and a conical portion are combined as a shape tapered toward the tip. In the example shown in fig. 3, the bottom surface of the cylindrical portion is circular with the same diameter as the end surface of the 1 st member 1, and the bottom surface of the conical portion is circular with the same diameter. The shape of the 2 nd member 3 of the present example can increase the volume of the 2 nd member 3 as compared with the shape shown in fig. 2. By increasing the volume of the 2 nd member 3 having low thermal conductivity, the end surface of the 1 st member 1 can be protected by the 2 nd member 3 while further reducing the temperature of the front end of the heater 10.
In the case where the 2 nd member 3 has a tapered shape as described above, the tip portion may be curved (R-shaped). Thus, when the heater 10 pierces the object to be heated, the possibility of breakage of the distal end portion of the 2 nd member 3 can be reduced.
As shown in fig. 4, the 1 st member 1 and the 2 nd member 3 may be joined by a glass material 4. This can improve the strength of the joint between the 1 st member 1 and the 2 nd member 3. As shown in fig. 13 and 14, the 1 st member 1 may be a columnar member, the end face of the 1 st member 1 may be circular, and the face of the 2 nd member 3 joined to the 1 st member 1 may also be circular. In this case, the bonding area of the glass bonding can be widened, and therefore the strength of the heater 10 can be further improved.
Further, as shown in fig. 5, the 1 st member 1 and the 2 nd member 3 may be joined by a glass material 4, and the outer peripheral surfaces of the 1 st member 1 and the 2 nd member 3 may be covered with the glass material 4. This reduces the possibility of the object sticking to the surface of the heater 10 when the heater 10 is stuck into the object. As a result, corrosion of the heater 10 at the portion where the object to be heated is attached can be reduced, and the risk of damage to the heater 10 can be reduced. As a result, the durability of the heater 10 can be improved. In the heater 10, a part or the whole of the outer peripheral surface of the 1 st member 1 and a part or the whole of the outer peripheral surface of the 2 nd member 3 may be covered with the glass material 4. In the heater 10, the outer peripheral surface of the 1 st member 1 may be partially or entirely covered with the glass material 4, the outer peripheral surface of the 2 nd member 3 may not be covered with the glass material 4, a portion or entirely of the outer peripheral surface of the 2 nd member 3 may be covered with the glass material 4, and the outer peripheral surface of the 1 st member 1 may not be covered with the glass material 4.
As shown in fig. 6, the 1 st member 1 may have a convex portion 11 on the end surface, the 2 nd member 3 may have a concave portion 31 on the end surface, and the convex portion 11 may be inserted into the concave portion 31. Thus, the 1 st member 1 and the 2 nd member 3 are fitted to each other, and therefore, the possibility that the 2 nd member 3 is peeled from the 1 st member 1 can be reduced. As a result, the durability of the heater 10 can be improved.
As shown in fig. 7, the 2 nd member 3 may have a convex portion 32 on the end surface, the 1 st member 1 may have a concave portion 12 on the end surface, and the convex portion 32 may be inserted into the concave portion 12. Thus, the 2 nd member 3 is fitted to the 1 st member 1, and therefore, the possibility that the 2 nd member 3 is peeled from the 1 st member 1 can be reduced. As a result, the durability of the heater 10 can be improved.
As shown in fig. 8, the 2 nd member 3 may have a recess 31 on an end face, and the end face of the 1 st member may be a flat face. This makes it possible to form a void in the recess 31, reduce the heat conductivity from the 1 st member 1 to the 2 nd member 3, and lower the temperature of the tip of the heater 10.
As shown in fig. 9, the 1 st member 1 may have a recess 12 on an end surface, and the 2 nd member may have a flat end surface. This makes it possible to form a void in the recess 12, reduce the heat conductivity from the 1 st member 1 to the 2 nd member 3, and lower the temperature of the tip of the heater 10.
As described above, when the 1 st member 1 and the 2 nd member 3 are joined with the glass material 4, the glass material 4 may be placed in the concave portion 31 and the concave portion 12.
As shown in fig. 10, the 1 st member 1 may be cylindrical. This can reduce the heat capacity of the heater 10. Therefore, heat can be easily transmitted to the object to be heated. As a result, the heating rate of the object can be increased.
As shown in fig. 11, the 2 nd member 3 may have a projection 32 on the end face, and the projection 32 may be inserted into the inside of the 1 st member 1 in the cylindrical shape. This can improve the joining strength of the 1 st member 1 and the 2 nd member 3 while reducing the heat capacity of the heater 10.
As shown in fig. 12, a cigarette heating tool 100 according to an example of the present disclosure includes a heater 10 and a flange 6 for holding the heater 10. Thus, the durability of the heating tool for cigarettes can be improved while reducing the possibility of excessive temperature rise near the mouthpiece of the cigarettes. The cigarette heating tool 100 shown in fig. 12 is provided with the heater 10 shown in fig. 11, but the cigarette heating tool 100 of the present disclosure may be provided with any of the heaters 10 shown in fig. 1 to 10.
The present disclosure can be embodied in other various forms without departing from the spirit or essential characteristics thereof. Therefore, the foregoing embodiments are merely exemplary in all aspects, and the scope of the present invention is defined by the appended claims and not limited to the text of the specification. Further, all of the modifications and changes belonging to the claims are within the scope of the present invention.
