Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 2 to 4, the present invention provides a heating rod 10, which includes a substrate 200, a resistance wire 100 and a surface shell; the resistance wire 100 is printed on the substrate 200, the resistance wire 100 is bent back and forth to form a plurality of heating parts 130, and after the substrate 200 is rolled to form the heating rod 10, the heating parts 130 surround in the circumferential direction of the heating rod 10; the skin case is fixedly disposed on the base 200 to cover the resistance wire 100 between the base 200 and the skin case.
The heating portion 130 is formed into a 'snake-shaped' structure, when the substrate 200, the resistance wire 100 and the surface shell are molded and are wound into the columnar heating rod 10, the 'snake-shaped' heating portion 130 can surround the circumferential direction of the heating rod 10, so that the heating portion 130 can be perpendicular to the extending direction of tobacco shreds, the problem of 'burning missing' when gaps in the resistance wire 100 are aligned with the tobacco shreds is solved, and meanwhile, the plurality of heating portions 130 are formed in the axial direction of the heating rod 10, so that the sufficiency of heating the tobacco shreds can be ensured.
In a specific embodiment, as shown in fig. 2, the respective heating parts 130 may be uniformly distributed in the axial direction of the heating rod 10.
The interval between two adjacent heating parts 130 is the same, and the distribution of the plurality of heating parts 130 in the axial direction can ensure that the heating conditions of all tobacco shreds in the circumferential direction are consistent, so that the tobacco shreds are uniformly heated.
However, as shown in fig. 4, the front end of the heating rod 10 generally has a tip 11, and it is difficult to print the resistance wire 100 on the tip 11, so that the cut tobacco corresponding to the position of the tip 11 cannot be directly heated, and the cut tobacco located at the position of the tip 11 is wasted; in order to solve this problem, in this embodiment, as shown in fig. 3, a connection terminal 150 is provided on the resistance wire 100, and the density of the heating portion 130 on the resistance wire 100 away from the connection terminal 150 is greater than the density of the heating portion 130 on the resistance wire 100 close to the connection terminal 150.
As shown in fig. 2 and 3, the "density of the heating portions 130 on the resistance wire 100 away from the connection terminal 150" means the size of the gap 160 between two or more heating portions 130 located away from the connection terminal 150; "the density of the heating portions 130 on the resistance wire 100 near the connection terminal 150" means the size of the gap 160 between two or more heating portions 130 located near the connection terminal 150; therefore, the gap 160 between the two or more heating portions 130 far from the connection terminal 150 is smaller than the gap 160 between the two or more heating portions 130 near the connection terminal 150, so that the heating efficiency of the two or more heating portions 130 far from the connection terminal 150 is higher, the heating is more concentrated, the heat is transferred to the tobacco shred corresponding to the tip 11, the tobacco shred at the position can be heated to decompose smoke substances, and the tobacco shred waste is avoided.
The substrate 200 and the surface shell may be made of ceramic.
In the molding process, the resistance wire 100 is printed on the ceramic substrate 200, and then ceramic paste may be coated on the substrate 200 and fired to form the heating rod 10.
It should be noted that, because the thermal expansion coefficients of the stainless steel resistance wire 100 and the ceramic are different, in the firing process, the existing resistance wire 100 arranged in the axial direction of the heating rod as shown in fig. 1 has a relatively large length extending continuously in the axial direction, which causes a large deformation difference, and is easily broken in the firing process. In the embodiment, the resistance wires 100 arranged in a radial snake shape have relatively small length extending continuously in the axial direction, mainly in a radial surrounding distribution mode, and the deformation amount in the radial direction is very small, so that the problem of fracture in the firing process is effectively avoided.
Further, as shown in fig. 2 or fig. 3, the resistance wire 100 specifically includes a connection portion 140, and a left heating section 110 and a right heating section 120 that are symmetrically disposed, where the left heating section 110 and the right heating section 120 both include a plurality of heating portions 130, and ends of the left heating section 110 and the right heating section 120 that are far away from the connection terminal 150 are connected through the connection portion 140.
After the resistance wire 100 in the unfolded state shown in fig. 2 or fig. 3 is rolled into the heating rod 10, the heating portion 130 on the left heating section 110 and the heating portion 130 on the right heating section 120 are symmetrically distributed on the same circumference, so that the tobacco shreds on the same circumference can be uniformly heated to a greater extent, and the sufficiency of the thermal decomposition of substances in the tobacco shreds can be ensured.
The embodiment of the utility model provides a heating does not burn cigarette utensil is still provided, it includes the utility model discloses arbitrary embodiment provides a heating rod 10.
The embodiment of the utility model provides a heating rod and heating do not burn cigarette utensil, through the heating portion that sets up serpentine structure, can make the heating portion encircle in the circumference of heating rod, can make the extending direction of heating portion perpendicular to pipe tobacco from this, the problem of "leaking burning" takes place when having solved clearance in the current resistance wire and pipe tobacco alignment, simultaneously, through form a plurality of heating portions in the axial of heating rod to can guarantee the sufficiency to the pipe tobacco heating.
The structure, features and effects of the present invention have been described in detail above according to the embodiment shown in the drawings, and the above description is only the preferred embodiment of the present invention, but the present invention is not limited to the implementation scope shown in the drawings, and all changes made according to the idea of the present invention or equivalent embodiments modified to the same changes should be considered within the protection scope of the present invention when not exceeding the spirit covered by the description and drawings.
