Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 3 to 7, the present invention provides a heating wire assembly, which includes a heating element 101, a conductive connecting element 102 and at least one conductive clamping element 103, wherein each conductive clamping element 103 includes a substrate 103a and a plurality of clamping arms 103b formed by bending and extending two opposite sides of the substrate 103a, the clamping arms being arranged in an array, the ends of the conductive connecting element 102 and the ends of the heating element 101 are arranged on the substrate 103a in parallel at intervals, and are respectively wrapped by the clamping arms 103b at two sides to be clamped in one conductive clamping element 103; the clamping arms 103b located on two sides of the substrate and adjacent to each other are arranged in parallel and/or in a staggered manner. In addition, the heating wire assembly further includes an oil guide 104 for conveying the oil smoke for the heating member 101, and the heating member 101 is wound on the oil guide 104.
The relevant aspects of the invention will be explained in more detail below with reference to the drawings.
Fig. 3 is a schematic structural diagram of the heating wire assembly according to the first preferred embodiment of the present invention, and it can be seen that the heating wire assembly includes two conductive clamping members 103, and the heating element 101 has a first connection end 101a and a second connection end 101b disposed at both ends, and the conductive connection member 102 includes a first conductive connection member 102a electrically connected to the first connection end 101a through one of the conductive clamping members 103 and a second conductive connection member 102b electrically connected to the second connection end 101b through the other conductive clamping member 103.
The first conductive connecting part 101 and the second conductive connecting part 102 may be made of conductive materials such as gold, silver or copper, the surfaces of the first conductive connecting part 101 and the second conductive connecting part 102 are provided with insulating layers (not marked in the figure) which are uniformly coated, the insulating layers may be sprayed on insulating paints, such as rubber paint, plastic paint, etc., outside the first conductive connecting part 101 and the second conductive connecting part 102, or insulating sleeves, such as rubber sleeves, silica gel sleeves, etc., which are sleeved outside the first conductive connecting part 101 and the second conductive connecting part 102. The insulating layer of the portions of the first and second conductive connectors 101 and 102 held by the conductive holder 103 is peeled off to ensure electrical connection between the first and second conductive connectors 101 and 102 and the conductive holder 103.
The heat generating member 101 is made of an alloy material having a high resistivity, and is preferably integrally formed of the same material to have a filament-like structure, such as nichrome, inconel, ferrochrome, constantan, or the like. The heating element 101 is wound on the oil guiding element 104 in a spiral shape, and both ends of the heating element extend outwards to form a first connection end 101a and a second connection end 101b for being connected with the conductive connecting element 102 through the conductive clamping element 103.
Preferably, the conductive clamping member 103 connects the ends of the heating member 101 and the conductive connecting member 102 by riveting, that is, one end of the conductive connecting member 102 and one end of the heating member 101 are arranged on two sides of the substrate 103a at an interval in parallel, where the clamping arms 103b are arranged; then, the clamping arms 103b on both sides are bent oppositely to respectively coat the heating member 101 and the conductive connecting member 102; finally, the holding arms 103b on both sides are hammered so as to be closely attached to and clamp the heat generating member 101 and the conductive connecting member 102, respectively, thereby preventing looseness. Further, the cross-sectional shape of the conductive clamping member 103 to which the heat generating member 101 and the conductive connecting member 102 are fixed is similar to a butterfly shape or an arch shape.
In addition, the ends of the heating element 101 and the conductive connecting element 102 can be connected by welding, and the holding arms 103b on both sides of the substrate 103a are bent to form a space for accommodating the heating element 101 and the conductive connecting element 102, wherein the space is used for accommodating the heating element 101 and the conductive connecting element 102; then, the heating member 101 and the conductive connecting member 102 are inserted into a space formed by the holding arms 103b and held by the holding arms 103 b; finally, the heat generating member 101 and the conductive connecting member 102 are fixed by welding. The heat generating member 101 and the conductive connecting member 102 can be more reliably connected by clamping with the clamping arm 103b and assisting in welding.
In this embodiment, two sides of the substrate 103a on each conductive clamping member 103 are bent and extended to form four clamping arms 103b arranged in an array, and the end of the conductive connecting member 102 and the end of the heating member 101 are arranged on two sides of the substrate 103a in parallel at an interval. The two clamping arms 103b positioned on the same side are respectively coated to clamp the end parts of the conductive connecting piece 102 or the heating piece 101 so as to form multi-point fixation; any two clamping arms 103b have a gap or abut against each other between adjacent sides, thereby ensuring that each clamping arm 103b can be tightly attached to the outer surface of the conductive connecting part 102 or the heating part 101, avoiding the clamping arms 103b from overlapping each other and being unable to be tightly attached to the conductive connecting part 102 or the heating part 101, further avoiding the phenomena of loosening and the like in use due to the large gap between the clamping arms 103b and the conductive connecting part 102 or the heating part 101, and improving the reliability of the clamping action of the clamping arms 103 b.
The four clamping arms 103b of the conductive connecting piece 103 are divided into two rows, the two rows of clamping arms 103b are arranged in a one-to-one correspondence manner, wherein the conductive connecting piece 102 is fixed in the clamping arm 103b positioned on the same side of the substrate 103a, and the heating piece 101 is fixed in the clamping arm 103b on the other side.
It is understood that the number of the clamping arms 103b formed by bending and extending the two side edges of the substrate 103a on each conductive clamping member 103 is not limited to four in the present invention, and may be multiple, and the specific number is not limited to any specific number. The number of the clamping arms 103b on the same side of the substrate is two or more, so that the area of each clamping arm 103b is smaller, and bending processing during riveting is more convenient; meanwhile, when the clamping arms 103b are hammered, each clamping arm 103b can more easily and tightly adhere to the outer surface of the heating element 101 or the conductive connecting element 102 due to the reduction of the area, so that no gap exists between the clamping arms 103b and the heating element 101 or the conductive connecting element 102 to be fixed. In addition, the heating member 101 and the conductive connecting member 102 to be fixed are respectively clamped by at least two clamping arms 103b, and when any one clamping arm 103b is loosened or loosened, the connection between the member to be fixed and the conductive clamping member 103 cannot be influenced, so that the riveting defective rate is greatly reduced.
In this embodiment, the arrangement of the clamping arms 103b in an array is not limited to the opposite and parallel arrangement of the clamping arms 103b on two sides shown in the figure, and a relative staggered arrangement may also be adopted, as long as all the clamping arms 103b located on the same side can stably and reliably fix the conductive connecting member 102 or the heating member 101. Preferably, adjacent sides of any two of the gripping arms 103b have a gap or abut each other.
The conductive clamping member 103 may be made of a conductive material, preferably brass or cupronickel, and the first and second connection terminals 101a and 101b of the heat generating member 101 are preferably made of cupronickel. The cupronickel is a copper-based alloy with nickel as a main additive element, is silvery white and has metallic luster. The pure copper and nickel can obviously improve the strength, corrosion resistance, hardness and thermoelectric property, reduce the temperature coefficient of resistivity and have better mechanical and physical properties. In addition, a large amount of nickel elements contained in the cupronickel have better corrosion resistance, so that an oxide film can be formed on the surface to effectively avoid corrosion in a humid environment, and the short circuit and the open circuit of a heating wire circuit are avoided; meanwhile, the phenomenon that the patina is dissolved in the tobacco tar to influence the user experience is avoided.
Fig. 4 shows a perspective view of the conductive connecting member 103 in this embodiment, a substrate 103a of the conductive connecting member 103 includes a main body 103c having an arc-shaped cross section and a wing 103d having an arc-shaped cross section and formed by continuously bending and extending two opposite sides of the main body 103c, the side of the wing 103d away from the main body 103c is continuously bent and extended oppositely to form a plurality of clamping arms 103b, and one end of the conductive connecting member 102 and one end of the heating member 101 have a circular cross section and are respectively covered and fixed in a space surrounded by the wing 103c and the clamping arms 103 b; the multi-section arc design of the substrate 103a can ensure that the surfaces of the conductive connecting piece 103, the conductive connecting piece 102 with the circular cross section of the end part and the heating piece 101 are attached to each other, so that the connection is more reliable, the strength is better, and the deformation is not easy. One end of the conductive connecting member 102 with the insulation layer removed and one end of the heat generating member 101 are respectively in contact with and electrically connected to the conductive connecting member 103, and thus the conductive connecting member 102 and the heat generating member 101 are electrically connected through the conductive connecting member 103 made of a conductive material.
Fig. 5 shows a perspective view of the conductive connection member 103 of the heating wire assembly provided in the second preferred embodiment of the present invention, and compared with the first preferred embodiment, other structures of the heating wire assembly are the same as those of the first preferred embodiment, and are not repeated herein, but the difference lies in that the structure of the substrate 103a of the conductive connection member 103 in this embodiment is different.
In this embodiment, the substrate 103a of the conductive connecting member 103 also includes a main body 103c and two side wings 103d having an arc-shaped cross section and formed by bending and extending two opposite sides of the main body 103c, each side wing 103d far away from the main body 103c is bent and extended to form at least two holding arms 103b, and one end of the conductive connecting member 102 and one end of the heating member 101 are respectively covered and fixed in a space surrounded by the side wings 103c and the holding arms 103 b.
However, the body 103c is not curved in cross section as described above, but rather the bottom of the body 103c in this embodiment is slightly concave and the top surface in contact with the gripping arm 103b is flat. Due to the design, the volume of the conductive clamping piece 103 is smaller, and the compactness of the electronic cigarette structure is improved; meanwhile, the clamping arm 103b can be kept attached to the substrate 103a to a greater extent, and the clamping arm 103b can also be attached to the outer surface of the heating element 101 or the conductive connecting element 102 to a greater extent, so that stable and reliable mechanical connection and electrical connection can be formed.
Fig. 6 is a schematic view showing a heating wire assembly according to a third preferred embodiment of the present invention, which shows a case where two clamping arms are provided on the conductive connecting member 103, as compared with the previous embodiments.
In addition, the heat generating member 101 in this embodiment is flat and has at least one plane, and the cross section may be a semicircle, a semi-ellipse, a polygon, etc. A plane of the heat generating member 101 faces the oil guide member 104 and is attached to the outer surface of the oil guide member 104, and is wound around the oil guide member 104. The binding face of the heating part 101 and the oil guiding part 104 is a plane, so that the contact area between the heating part 101 and the oil guiding part 104 is obviously increased, the atomization amount generated in unit time is further improved, the atomization effect is enhanced, and the user experience is improved.
Preferably, the cross section of the heat generating member 101 is polygonal, such as rectangular, square, trapezoidal, symmetrical hexagonal, etc., to facilitate the production operation. More preferably, the cross section of the heating element 101 is rectangular, the length is 0.3mm-1mm, and the width is 0.05mm-0.2 mm.
As shown in fig. 7, the cross section of the heating element 101 in this embodiment is rectangular, two holding arms 103b of the conductive holding member 103 are respectively attached to the heating element 101 and the conductive connecting member 102 by riveting, and a gap is formed between adjacent sides of the two holding arms 103 b.
It is understood that the cross-section of the conductive connecting member 102 may also have at least one plane, preferably a polygon, such as a rectangle, a square, a trapezoid, a symmetrical hexagon, etc., which may be the same as or different from the shape of the heat generating member 101, and is not limited herein.
In the heating wire assembly provided by the invention, one end of the conductive connecting piece 102 is externally connected and electrically connected to an external power supply, the other end is electrically connected with the heating piece 101 through the conductive clamping piece 103, and the heating piece 101 is electrified to be heated and heated so that the tobacco tar provided by the oil guiding piece 104 is heated and atomized into smoke.
