Abstract
Description
Technical Field
[0001] This application relates to the field of heating technology, specifically to a heating device. Background Technology
[0002] In related technologies, the heating device includes a main ring shell and a heating wire sleeved on the main ring shell. A limiting plate is typically installed on the main ring shell to limit the heating wire, creating a gap between the heating wire and the main ring shell. When the main ring shell is made of plastic, a heat insulation sheet is needed between the heating wire and the main ring shell to reduce the impact of heat on the main ring shell. Heat insulation sheets are usually installed on each limiting plate; however, when there is only one heat insulation sheet, a long cut is required on one side of the limiting plate to achieve stable assembly, with part of the heat insulation sheet inserted into the cut for fixation. This long cut on the limiting plate severely affects its structural strength, making it prone to bending, deformation, or breakage, seriously impacting product quality.
[0003] In view of the above, this application is hereby submitted. Utility Model Content

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0040] like Figures 1 to 6 As shown, this application embodiment provides a heating device, including: a main ring shell 1, multiple limiting plates 2, a heating wire 3, and two inner heat insulation sheets 4. Each of the limiting plates 2 is disposed on the main ring shell 1, and the limiting plates 2 are arranged sequentially at intervals along the length direction of the main ring shell 1. Each limiting plate 2 has a cutout 21 on both sides along its width direction, and the cutouts 21 on both sides are staggered radially along the main ring shell 1, that is, the cutouts 21 on both sides are staggered in the height direction. The heating wire 3 is located on the outer side of the main ring shell 1, and the heating wire 3 is respectively positioned and engaged with each of the limiting plates 2. Two inner heat insulation sheets 4 are arranged sequentially along the width direction of the limiting plate 2. The two inner heat insulation sheets 4 are respectively snapped onto the cut-out portions 21 on both sides of each limiting plate 2. The inner heat insulation sheets 4 are located between the heating wire 3 and the main ring shell 1, and there is a gap between them to reduce the conduction of heat to the main ring shell 1 and avoid the main ring shell 1 from thermal deformation under high temperature.
[0041] The heating device can be installed on an air outlet device, which has an annular air outlet channel. The heating device of this application is roughly annular and can be installed in the annular air outlet channel to heat the air flowing through it.
[0042] Compared to the related technologies that only have one inner heat insulation sheet 4, the present application has two inner heat insulation sheets 4, which can appropriately reduce the width of a single inner heat insulation sheet 4, and at the same time reduce the length of the single cutout 21 on both sides of the limiting plate 2, so as to avoid seriously affecting the structural strength of the limiting plate 2.
[0043] like Figure 4 As shown, this application provides two staggered cutouts 21 on both sides of the limiting plate 2 along the width direction, which can facilitate the assembly of two inner heat insulation sheets 4 respectively. This ensures the heat insulation effect while reducing the length of a single cutout 21 on the limiting plate 2, ensuring that the structural strength of the limiting plate 2 meets the standard and extending the product life.
[0044] In some possible implementation schemes, combined Figure 5 and Figure 6As shown, the inner heat insulation sheet 4 includes multiple heat insulation sections 41. Adjacent heat insulation sections 41 are connected by limiting sections 42. The limiting sections 42 are located on one side of the heat insulation section 41 along the width direction. The limiting sections 42 are inserted into the corresponding cutouts 21. The heat insulation sections 41 on both sides of the limiting sections 42 are located on both sides of the corresponding limiting plates 2.
[0045] In some possible implementations, one of the two inner heat insulation sheets 4 extends beyond the other along one side of its width. That is, the two inner heat insulation sheets 4 only partially overlap, and along the thickness direction of the heating device, the total effective width of the two inner heat insulation sheets 4 is greater than the width of a single inner heat insulation sheet 4, but less than the sum of the widths of the two inner heat insulation sheets 4.
[0046] The partial overlap of the two inner heat insulation sheets 4 can be understood as the projection of one inner heat insulation sheet 4 onto the other inner heat insulation sheet 4 falling only on one side along the width direction, while not falling on the other side. The two inner heat insulation sheets 4 can be partially fitted together, or there can be a small gap between them.
[0047] In some possible implementations, a plurality of plug-in seats 11 are provided on one side of the outer surface of the main ring shell 1, and each of the limiting plates 2 is plugged into the corresponding plug-in seat 11. The plug-in seats 11 are arranged sequentially at intervals along the circumference of the main ring shell 1, which facilitates the rapid assembly of each limiting plate 2.
[0048] In some possible implementations, the connector 11 has two spaced-apart inserts forming a slot between them, into which the limiting plate 2 is inserted. A stop block may be provided at one end of each insert along the width direction of the main annular shell 1, so that after the limiting plate 2 is inserted into the slot, one side of the limiting plate 2 can abut against the stop block.
[0049] In some possible implementations, the heating device may include two heating wires 3 arranged sequentially along the radial direction of the main annular shell 1, or sequentially along the thickness direction of the inner heat insulation sheet 4. This causes the two heating wires 3 to be staggered, reducing wind resistance and increasing contact with the flowing air.
[0050] In some possible implementation schemes, combined Figure 1 and Figure 2 As shown, the limiting plate 2 has two notches 22 on the side opposite to the main ring shell 1, and the two heating wires 3 are respectively disposed through the corresponding notches 22. The two notches 22 can respectively restrict the position of the two heating wires 3, so that the heating wires 3 extend along a set trajectory.
[0051] In some possible implementations, the two notches 22 are arranged sequentially along the width direction of the limiting plate 2, so that the two heating wires 3 are staggered left and right. At the same time, the depth of one notch 22 is greater than the depth of the other notch 22, so that the two heating wires 3 are staggered vertically.
[0052] In some possible implementations, the heating device may include a high-temperature rope 6, and the heating wire 3 may be spiral or corrugated, with an internal channel through which the high-temperature rope 6 passes. The high-temperature rope 6 may be made of a high-temperature resistant material. When the heating wire 3 breaks, the high-temperature rope 6 can limit the broken heating wire 3 to prevent it from contacting other locations and causing a safety accident. The high-temperature rope 6 may be fixedly connected to a portion of the limiting plate 2.
[0053] Optionally, such as Figures 1 to 3 As shown, the heating device includes an outer heat insulation sheet 5, which covers the outer side of each of the limiting plates 2, and a heating wire 3 is located between the inner heat insulation sheet 4 and the outer heat insulation sheet 5.
[0054] This application, through the setting of the outer heat insulation sheet 5 and the inner heat insulation sheet 4, can insulate both sides of the heating wire 3, reduce the heat transferred from the heating wire 3 to the blower, and prevent the corresponding structure of the blower from being deformed by heat or causing safety accidents.
[0055] It should be noted that in this application, the limiting plate 2, the inner heat insulation sheet 4 and the outer heat insulation sheet 5 can all be mica sheets, which have insulation and low thermal resistance functions.
[0056] Two notches 22 divide the limiting plate 2 into three insertion parts. The middle insertion part can be inserted into the corresponding insertion hole on the outer heat insulation sheet 5. Limiting platforms are provided on the edges of the two insertion parts to limit the insertion on both sides of the outer heat insulation sheet 5.
[0057] This application improves the heat insulation effect by setting an outer heat insulation sheet 5 and an inner heat insulation sheet 4, which allows the blower to be equipped with a high-power heating device. That is, the heating device of this application can be equipped with two heating wires 3 to improve heating efficiency and enhance product performance.
