[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0020] 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. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figures 1 to 4 As shown, this application provides a heating device, including: a main annular shell 1, multiple support plates 2, a first heating wire 3, and a first heat insulation plate 5. Each support plate 2 is mounted on the main annular shell 1, and the support plates 2 are arranged sequentially at intervals along the circumference of the main annular shell 1. A first notch 21 is provided on one side of some support plates along the centerline of the main annular shell 1, and a first notch 21 is provided on the other side of some support plates along the centerline of the main annular shell 1. The first heating wire 3 passes through the first notch 21 of each support plate 2. The first heat insulation plate 5 is disposed on each support plate 2, extending along the circumference of the main annular shell 1, and the first heating wire 3 is located between the main annular shell 1 and the first heat insulation plate 5. This application provides two types of support plates 2 with different positions of the first notch 21, so that the two types of support plates 2 are respectively confined to both sides of the first heating wire 3, thereby restricting the position of the first heating wire 3 and preventing it from detaching. The confining structure of the first heating wire 3 in this application is relatively simple, which is beneficial to improving the assembly efficiency of the heating device.

[0022] The support plate 2 is detachably mounted on the main ring shell 1. When assembling the first heating wire 3, it is not necessary to first install each support plate 2 and then sequentially pass the first heating wire 3 through the through holes on each support plate 2. Instead, the first heating wire can be pre-positioned (e.g., connected to the end plates at both ends), and then each support plate 2 can be installed sequentially, so that the first notch 21 of the support plate 2 supports the first heating wire 3. This eliminates the need for precise wire-threading, significantly improving the assembly efficiency of the first heating wire.

[0023] In some possible implementations, the distance between the first notch 21 and the centerline of the main annular shell 1 gradually increases in the direction from the closed side to the open side of the first notch 21.

[0024] That is, the extension direction of the first notch 21 is not parallel to the center line a of the main ring shell 1, but has an angle with the center line a of the main ring shell 1. Moreover, the inner side of the first notch 21 is low and the open side is high, which is conducive to limiting the first heating wire 3 and preventing the first heating wire 3 from sliding out locally along the first notch 21.

[0025] In some possible implementations, a plurality of slots 11 are provided on one side of the outer convex surface of the main ring shell 1, and each of the support plates 2 can be inserted into or removed from the corresponding slot 11. The support plates 2 and the slots 11 are connected and engaged, making assembly and disassembly relatively convenient.

[0026] like Figure 4 As shown, in each of the support plates 2, the first notches 21 of two adjacent support plates 2 can be arranged in opposite directions, or the first notches 21 of several support plates 2 can be arranged in opposite directions.

[0027] In some possible implementations, the heating device includes a second heating wire 4, and a second notch 22 is provided on the side of the support plate 2 opposite to the main ring shell 1, and the second heating wire 4 is provided through the second notch 22 of each of the support plates 2.

[0028] 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 inside the annular air outlet channel to heat the flowing air. In this embodiment, the heating efficiency is improved by setting two heating wires. The two heating wires are arranged sequentially along the radial direction of the main annular shell 1, increasing the contact area with the flowing air and further improving the air heating efficiency.

[0029] In some possible implementations, the support plate 2 is provided with two inserts 23 at one end away from the main ring shell 1. The two inserts 23 are respectively located on both sides of the second notch 22. The first heat insulation plate 5 is provided with insertion holes 51. When the first heat insulation plate 5 is connected to each of the support plates 2, each insert 23 is inserted into the corresponding insertion hole 51.

[0030] In some possible implementations, the heating device includes a second heat insulation plate 6 disposed on the outer surface of the main ring shell 1, a first heating wire 3 located between the first heat insulation plate 5 and the second heat insulation plate 6, the outer surface of the main ring shell 1 having ribs with slots provided on the ribs, and the second heat insulation plate 6 having clearance openings at the locations corresponding to the ribs.

[0031] The embodiments of this application significantly improve the heat insulation effect by setting the first heat insulation plate 5 and the second heat insulation plate 6 respectively, so that the blower can be equipped with a high-power heating device. That is, the heating device of this application can be equipped with two heating wires to improve heating efficiency and enhance product performance.

[0032] In some possible implementations, the heating device includes two end plates 7, both of which are disposed on the main ring shell 1, each of the support plates 2 is located between the two end plates 7, the two ends of the first heating wire 3 extend to the two end plates 7 respectively, and the two ends of the first heat insulation plate 5 are respectively connected to the two end plates 7.

[0033] In some possible implementations, the heating device includes a temperature control circuit 8 disposed on the end plate 7 and / or support plate 2, the temperature control circuit 8 being electrically connected to the first heating wire 3, and a power line 9 being electrically connected to the temperature control circuit 8.

[0034] One end of the temperature control circuit 8 is connected to the power cord, and the other end can be connected to the first heating wire 3 and the second heating wire 4 respectively. The positive terminal of the power cord 9 can be connected to the temperature control circuit 8, and the negative terminal can be connected to the end of the first heating wire 3 and the second heating wire 4 away from the temperature control circuit 8. The first heating wire 3 and the second heating wire 4 are connected in parallel, and the temperature control circuit 8 and the whole system consisting of the first heating wire 3 and the second heating wire 4 are connected in series.

[0035] In some possible implementations, the temperature control circuit 8 includes a conductor and a temperature controller 83. The conductor is connected on both sides to an end plate 7 and a support plate 2 near the end plate 7, respectively. The temperature controller 83 is located between the end plate 7 and the support plate 2, and is positioned on the conductor facing the first heating wire 3. The temperature controller 83 has a temperature sensor, a controller, and a circuit breaker. The controller is electrically connected to both the temperature sensor and the circuit breaker. The temperature sensor, located near the first heating wire 3, monitors the heat. When the monitored heat is too high, the controller controls the circuit breaker to open, de-energizing the first heating wire 3 and the second heating wire 4. Once the heat drops to a suitable level, the controller re-opens the circuit breaker to resume heating. It should be noted that the temperature controller 83 is a mature product in the art, and this application directly adopts existing technology without improving the existing temperature controller 83.

[0036] In some possible implementations, the conductor includes a first conductive segment 81 and a second conductive segment 82, both ends of which extend to the end plate 7 and the support plate 2, respectively. The first conductive segment 81 and the second conductive segment 82 are electrically connected at one end of the support plate 2. The first conductive segment 81 is electrically connected to the power line 9 at one end of the end plate 7. The second conductive segment 82 is electrically connected to the first heating wire 3 at one end of the end plate 7. A temperature controller 83 is disposed on the first conductive segment 81 or the second conductive segment 82 on the side close to the first heating wire 3.

[0037] It should be noted that the conductor may include multiple conductive strips, which are electrically connected in sequence, and each conductive strip constitutes the first conductive segment 81 and the second conductive segment 82. Alternatively, the first conductive segment 81 and the second conductive segment 82 may each include several independent conductive strips.
