[0047] The following is for reference. Figures 1-12 The present invention describes a heating assembly 3 and a heater 100 according to an embodiment of the present invention.
[0048] Reference Figure 1 , Figure 2 and Figure 3 According to an embodiment of the present invention, the heating assembly 3 includes a heating element 31 and a first mounting bracket 321. The heating element 31 extends along a first direction, and the first mounting bracket 321 is adapted to be connected to an external fixing member. One of the heating element 31 and the first mounting bracket 321 is provided with a first insertion portion 314 and the other is provided with a first insertion groove 3211. The first insertion portion 314 is at least partially located in the first insertion groove 3211 and supported on the inner wall of the first insertion groove 3211 so that the heating element 31 is connected to the mounting bracket 3211. In the first direction, the minimum length of the first insertion groove 3211 is greater than the thickness of the first insertion portion 314, and the first insertion portion 314 is movable relative to the first insertion groove 3211.
[0049] For example, the heating element 31 may have a first insertion portion 314, and the first mounting bracket 321 may have a first insertion groove 3211, with the first insertion portion 314 at least partially located within the first insertion groove 3211. Alternatively, the heating element 31 may have a first insertion groove 3211, and the first mounting bracket 321 may have a first insertion portion 314, with the first insertion portion 314 at least partially located within the first insertion groove 3211.
[0050] The first mounting bracket 321 is adapted to connect with an external fixing component. The heating element 31 is connected to the mounting bracket 32 through the cooperation of the first insertion part 314 and the first insertion slot 3211, thereby installing the heating element 31 onto the external fixing component. It should be noted that when the heating element 31 is applied to the heater 100, the external fixing component can be the inner wall of the air duct of the heater 100, or the shell 1 of the heater 100. The external fixing component can also be other structures, and this utility model does not limit this.
[0051] Research has shown that heating element 31 tends to stretch along its length after prolonged high-temperature operation, increasing its length. In this embodiment of the invention, heating element 31 extends along a first direction, and when it deforms, its length in the first direction increases.
[0052] In this embodiment of the invention, the first insertion part 314 can move relative to the first insertion groove 3211 in the first direction, that is, the heating element 31 can move relative to the first mounting bracket 321 in the first direction. When the heating element 31 deforms, the first insertion part 314 can move relative to the first insertion groove 3211, providing room for the deformation of the heating element 31 and preventing the heating element 31 from bending.
[0053] In some embodiments, the first direction is a vertical direction, and the inner wall of the first insertion groove 3211 includes a top wall and a bottom wall, both of which can limit the displacement of the first insertion part 314.
[0054] In some application scenarios, the heating element 31 in the first direction includes a first end and a second end. The first end of the heating element 31 is mounted to an external fastener via a first mounting bracket 321, and the second end of the heating element 31 is fixed to the external fastener via other structures.
[0055] When the heating element 31 deforms, because the second end of the heating element 31 is fixed to the external fastener, the first end of the heating element 31 can move in the first direction relative to the first mounting bracket 321. The first end of the heating element 31 has a deformable space, which allows the heating element 31 to extend along the first direction, thus avoiding bending of the heating element 31.
[0056] In other application scenarios, the heating element 31 is mounted to an external fastener via a first mounting bracket 321, which further increases the deformable space of the heating element 31 and further reduces the risk of bending of the heating element 31.
[0057] In some other embodiments, a plurality of first mounting brackets 321 are spaced apart in the first direction, and the heating element 31 is connected to the plurality of first mounting brackets 321. In this embodiment of the present invention, the heating element 31 is connected to an external fastener through the plurality of first mounting brackets 321, thereby improving the stability of the heating element 31 relative to the external fastener.
[0058] According to the heating assembly 3 of this utility model embodiment, the heating element 31 is adapted to be installed to an external fixing member via a first mounting bracket 321. The heating element is connected to the mounting bracket 32 via the cooperation of a first insertion part 314 and a first insertion groove 3211. The first insertion part 314 can move relative to the first insertion groove 3211 in a first direction, providing room for deformation of the heating element 31, avoiding bending of the heating element 31, extending the service life of the heating assembly 3, and also improving the safety of the equipment equipped with the heating assembly 3 of this utility model embodiment.
[0059] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the heating element 31 includes a first electrode 311, a second electrode 312, and at least one PTC element 313. The first electrode 311 and the second electrode 312 are spaced apart along a second direction, and each PTC element 313 is disposed between the first electrode 311 and the second electrode 312. Each PTC element 313 is electrically connected to the first electrode 311 and the second electrode 312, respectively. The first direction is perpendicular to the second direction.
[0060] Each PTC element 313 is electrically connected to the first electrode plate 311 and the second electrode plate 312 respectively. The first electrode plate 311 and the second electrode plate 312 can be used as conductive media to be electrically connected to an external power source. When the external power source is turned on, current can flow into the PTC element 313. The PTC element 313 can generate heat after being energized, thereby realizing the heating function of the heating element 31. In addition, the first electrode plate 311 and the second electrode plate 312 can also play the role of transferring the heat generated by the PTC element 313, which is conducive to increasing the heating area of the heating element 31, thereby improving the heating efficiency and heating uniformity of the heating element 31.
[0061] In some further embodiments, the heating element 31 has a plurality of PTC elements 313, which are spaced apart along a first direction, and an air passage space is defined between adjacent PTC elements 313.
[0062] Through the above technical solution, when air passes through the heating component 3, some air can pass through the air passage space to reduce the wind resistance of the heating component 3, which is conducive to increasing the air volume of the heater 100; at the same time, it also increases the contact area between the first electrode plate 311 and the second electrode plate 312 and the air, improves the heat dissipation efficiency of the heating component 3, and is conducive to increasing the heating effect of the heater 100.
[0063] Reference Figure 2 , Figure 3 and Figure 4In some embodiments, in the first direction, the thickness of the first insertion portion 314 is w1, the minimum length of the first insertion groove 3211 is w2, and w2-w1≥1mm.
[0064] In other words, the first insertion part 314 can be displaced by at least 1 mm relative to the first insertion groove 3211, providing sufficient room for the deformation of the heating element 31 and further reducing the risk of the heating element 31 bending.
[0065] In some specific embodiments, w2-w1 can be 1mm, 1.3mm, 1.5mm, 2mm or other sizes, and this utility model does not impose specific limitations on this.
[0066] Reference Figure 4 , Figure 5 and Figure 6 In other embodiments, the first direction is the thickness direction of the first insertion portion 314, the first insertion portion 314 also extends along a second direction, and the thickness of a portion of the first insertion portion 314 in the second direction is different from the thickness of the other portions.
[0067] In any cross section perpendicular to the second direction, the thickness of the first insertion part 314 is w3, the length of the first insertion groove 3211 in the first direction is w4, and w4-w3≥1mm.
[0068] In other words, the thickness of each part of the first insertion part 314 in the second direction is less than the length of the first insertion groove 3211, thereby ensuring that the first insertion part 314 can move within the first insertion groove 3211.
[0069] In some specific embodiments, w4-w3 can be 1mm, 1.3mm, 1.5mm, 2mm or other sizes, and this utility model does not impose specific limitations on this.
[0070] In some specific embodiments, a first insertion slot 3211 is disposed on a first mounting bracket 321, and the length of the first insertion slot 3211 gradually decreases in the direction away from the heating element 31. A first insertion portion 314 is disposed on one side of the heating element 31 in the second direction, and the thickness of the first insertion portion 314 gradually decreases in the direction away from the heating element 31, so that the thickness of the first insertion portion 314 is always less than the length of the first insertion slot 3211 in the first direction, thereby ensuring that the first insertion portion 314 can move within the first insertion slot 3211.
[0071] Reference Figure 1 , Figure 7 and Figure 8In some embodiments, the heating assembly 3 includes a plurality of mounting brackets 32, one of which is a first mounting bracket 321 and the other is a second mounting bracket 322. One of the second mounting bracket 322 and the heating element 31 is provided with a second insertion part 315 and the other is provided with a second insertion groove 3221. The second insertion part 315 is located in the first insertion groove 3211. In a first direction, the opposite sidewalls of the second insertion part 315 are in contact with the second insertion groove 3221.
[0072] For example, the heating element 31 may have a second insertion portion 315, and the second mounting bracket 322 may have a second insertion groove 3221, with the second insertion portion 315 at least partially located within the second insertion groove 3221. Alternatively, the heating element 31 may have a second insertion groove 3221, and the second mounting bracket 322 may have a second insertion portion 315, with the second insertion portion 315 at least partially located within the second insertion groove 3221.
[0073] In this embodiment of the invention, the heating element 31 is adapted to be mounted to an external fastener via multiple mounting brackets 32, effectively improving the stability of the heating element 31's mounting. Furthermore, the opposing sidewalls of the second insertion portion 315 in the first direction are in contact with the second insertion groove 3221, restricting the movement of the heating element 31 relative to the second mounting bracket 322 in the first direction, further improving the stability of the connection between the heating element 31 and the second mounting bracket 322, that is, further improving the stability of the connection between the heating element 31 and the external fastener.
[0074] In some specific embodiments, the heating element 31 in the first direction includes a first end and a second end. The first end of the heating element 31 is mounted to an external fixing member by a first mounting bracket 321, and the second end of the heating element 31 is fixed to the external fixing member by a second mounting bracket 322.
[0075] When the heating element 31 deforms, because the second end of the heating element 31 is fixed to the external fastener, the first end of the heating element 31 can move in the first direction relative to the first mounting bracket 321. The first end of the heating element 31 has a deformable space, which allows the heating element 31 to extend along the first direction, thus avoiding bending of the heating element 31.
[0076] In some embodiments, the second mounting bracket 322 and the first mounting bracket 321 have the same shape.
[0077] The above technical solution reduces the mold opening cost of multiple mounting brackets 32, reduces the cost of heating component 3, reduces the connection difficulty between heating element 31 and multiple mounting brackets 32, and improves the assembly efficiency of heating component 3.
[0078] In some embodiments, each mounting bracket 32 is provided with a mounting hole 323, and a fixing connector passes through the mounting hole 323 to be fixed to an external fixing member to connect the mounting bracket 32 to the external fixing member. The fixing connector can be a screw or bolt, which provides a reliable connection at a low cost.
[0079] In this embodiment of the utility model, the structure of the mounting bracket 32 for connecting external fasteners is simple, which reduces the processing difficulty of the mounting bracket 32 and the cost of the heating component 3; and the connection method between the mounting bracket 32 and the external fasteners is simple, which reduces the installation difficulty of the heating component 3.
[0080] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, at least one mounting hole 323 on the mounting bracket 32 extends along a first direction so that the position of the respective mounting bracket 32 relative to the external fastener is adjustable.
[0081] Mounting holes 323 on mounting bracket 32 extend in a first direction, allowing mounting bracket 32 to move relative to external fasteners in the first direction.
[0082] If the deformation of the heating element 31 is large and the space between the first insertion part 314 and the first insertion groove 3211 is insufficient for the heating element 31 to extend, the position of the mounting bracket 32 in the first direction can be adjusted to further increase the space for the heating element 31 to deform, thereby further reducing the risk of the heating element 31 bending and extending the service life of the heating assembly 3.
[0083] In some specific embodiments, the mounting hole 323 on the second mounting bracket 322 extends along the first direction. In other embodiments, the mounting hole 323 on the first mounting bracket 321 may also extend along the first direction. In still other embodiments, the mounting holes 323 on both the first mounting bracket 321 and the second mounting bracket 322 may extend along the first direction. This utility model does not limit this.
[0084] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, multiple heating elements 31 are provided, and the multiple heating elements 31 are all disposed on the mounting bracket 32 and arranged at intervals along the second direction, which is perpendicular to the first direction.
[0085] This utility model embodiment is provided with multiple heating elements 31, which effectively improves the heating efficiency of the heating component 3, and the multiple heating elements 31 are all provided on the mounting bracket 32, which improves the assembly efficiency of the heating component 3.
[0086] In some embodiments, one of each mounting bracket 32 and heating element 31 is provided with a first positioning groove 324 and the other is provided with a positioning part, the positioning part and the side wall of the first positioning groove 324 are in contact engagement.
[0087] For example, the mounting bracket 32 may be provided with a first positioning groove 324, and the heating element 31 may be provided with a positioning part, with the positioning part and the side wall of the first positioning groove 324 in contact and cooperate; or the mounting bracket 32 may be provided with a positioning part, and the heating element 31 may be provided with a first positioning groove 324, with the positioning part and the side wall of the first positioning groove 324 in contact and cooperate.
[0088] The contact and engagement between the positioning part and the side wall of the first positioning groove 324 restricts the movement of the heating element 31 in the second direction, effectively improving the stability of the connection between the heating element 31 and the mounting bracket 32.
[0089] In some preferred embodiments, the mounting bracket 32 is provided with a first positioning groove 324, and the portion of the heating element 31 inserted into the first positioning groove 324 defines the positioning part.
[0090] The above technical solution helps to reduce the thickness of the heating element 31 in the second direction, thereby reducing the overall volume of the heating assembly 3 and reducing the wind resistance of the heating assembly 3.
[0091] In some further embodiments, the first insertion portion 314 is an insertion protrusion protruding from the positioning portion.
[0092] In this embodiment of the invention, the first insertion part 314 has a simple structure, which facilitates the processing of the heating element 31 and reduces the cost of the heating assembly 3.
[0093] Reference Figure 3 and Figure 7 In some embodiments, each mounting bracket 32 is provided with a communicating groove having a mounting opening 325 in a third direction. A portion of the opposite sidewall of the communicating groove is recessed to define a first insertion groove 3211 or a second insertion groove 3221. The remaining portion of the communicating groove is a first positioning groove 324. The heating element 31 is adapted to be inserted into the first positioning groove 324 through the mounting opening 325. The first insertion part 314 is adapted to be inserted into the first insertion groove 3211 through the mounting opening 325. The second insertion part 315 is adapted to be inserted into the second insertion groove 3221 through the mounting opening 325. The first direction, the second direction, and the third direction are perpendicular to each other.
[0094] For example, the plurality of mounting brackets 32 include a first mounting bracket 321 and a second mounting bracket 322.
