[0025] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" 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; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] Example 1: As Figures 1 to 3 As shown, the novel heat dissipation structure of the electric heating appliance in this embodiment includes a housing 1 and a heating device 2 disposed inside the housing 1. The heating device 2 includes a heating element 3 and a heat insulation cover 4. The heat insulation cover 4 separates the heating element 3 from the housing 1. A heat dissipation guiding cavity 41 and an air outlet 42 are formed between the heat insulation cover 4 and the heating element 3. The air outlet 42 connects the heat dissipation guiding cavity 41 to the outside. A heat dissipation fan 5 is provided on the heat insulation cover 4. The heat dissipation fan 5 blows air into the heat dissipation guiding cavity 41, causing the heat dissipation airflow to flow to the outside through the heat dissipation guiding cavity 41 and the air outlet 42. In this embodiment, by setting a heat insulation cover 4 between the housing 1 and the heating element 3, and by using the heat dissipation fan 5 to blow air into the heat dissipation guiding cavity 41 for heat dissipation when the electric heating appliance is heating, the heat dissipation airflow is efficiently directed to the outside through the air outlet 42. The heat dissipation airflow path is referenced. Figure 1And Figure 2 The arrows shown point to the fact that the heat of the heat-generating component 3 is effectively prevented from being transferred to the outer shell 1 by the double insulation of the heat shield 4 and the flowing heat dissipation air flow, thus effectively reducing the temperature of the outer shell 1 and other electrical devices inside the outer shell 1, which is conducive to improving the service life of the electric heating appliance and facilitating the user's access to the outer shell to operate the electric heating appliance, thereby improving the user's experience.

[0027] Further, the heat-generating component 3 includes a heat-conducting panel 31 and a heat-generating element 32 arranged on the lower side of the heat-conducting panel 31, as shown in Figure 2 As shown, the air outlets 42 are distributed around the heat-conducting panel 31. The structure of the air outlets 42 arranged around the heat-conducting panel 31 can maximize the area of the air outlets 42, thereby facilitating the efficient outflow of the heat dissipation air flow in the heat dissipation flow cavity 41 and improving the heat dissipation efficiency of the heat-generating component 3.

[0028] Further, an electrical device assembly cavity 11 is formed between the heat shield 4 and the outer shell 1, and an electrical device 6 is arranged in the electrical device assembly cavity 11. The electrical device 6 is provided with a heat dissipation element 62 that can communicate with the heat dissipation flow cavity 41. The heat dissipation element 62 can quickly transfer the heat on the electrical device 6 to the heat dissipation flow cavity 41, and then the heat dissipation fan 5 can quickly dissipate the heat in the heat dissipation flow cavity 41, thereby further improving the heat dissipation effect of the electrical device 6.

[0029] Further, in order to facilitate the installation of the heat dissipation fan 5 on the heat shield 4, a fan mounting rack 43 that can communicate with the heat dissipation flow cavity 41 is arranged on the heat shield 4, and the heat dissipation fan 5 is arranged in the fan mounting rack 43. Specifically, the heat dissipation fan 5 is detachably mounted on the heat shield 4 through the mounting rack. The heat dissipation element 62 includes heat dissipation fins 63 that are inserted into the fan mounting rack 43 and located on the air outlet side of the heat dissipation fan 5. Specifically, in order not to affect the blowing and heat dissipation effect of the heat dissipation fan 5 on the heat dissipation flow cavity 41, the heat dissipation fins 63 can be provided with hollow parts, such as a mesh structure. By arranging the heat dissipation fins 63 directly on the air outlet side of the heat dissipation fan 5, the heat on the electrical device 6 can be more efficiently conducted to the air outlet side of the heat dissipation fan 5 through the heat dissipation element 62 and the heat dissipation fins 63, so that the heat dissipation fan 5 can dissipate heat, thereby increasing the heat dissipation effect of the electrical device 6.

[0030] Further, the heat generating assembly 3 comprises a support frame 7, the support frame 7 comprises a support frame body 71, a supporting piece 72 arranged on the support frame body 71 and a support leg 73, the support frame body 71 is used for supporting the heat conducting panel 31, the supporting piece 72 is used for supporting the heat generating piece 32, and the support leg 73 is used for being inserted into the heat insulation cover 4 to support the support frame body 71, so that the air outlet 42 is formed between the support frame body 71 and the heat insulation cover 4. In the installation process of the embodiment, the support leg 73 on the support frame 7 is installed in the corresponding hole position of the heat insulation cover 4, at this time, the support frame body 71 and the heat insulation cover 4 form the air outlet 42 structure, then the heat generating assembly 3 is placed on the support frame 7, that is, the heat generating piece 32 is placed on the supporting piece 72, and the heat conducting panel 31 is placed on the support frame body 71, so that the air outlet 42 structure is ensured to be formed, and the heat generating assembly 3 is conveniently and simply installed on the heat insulation cover 4, and the structure is simple and the installation is convenient.

[0031] Further, the heat dissipation fan 5 is arranged on the bottom wall or the side wall of the heat insulation cover 4. In the embodiment, in order to maximize the heat dissipation effect, the heat dissipation fan 5 is arranged in the middle of the bottom wall of the heat insulation cover 4, so that the heat dissipation fan 5 can blow from bottom to top to the heat generating assembly 3 and flow out through the air outlet 42. However, the installation position of the heat dissipation fan 5 on the heat insulation cover 4 is not unique in the embodiment, the heat dissipation fan 5 can be installed at a position other than the middle of the bottom wall of the heat insulation cover 4, such as shown in Figure 4 , and the heat dissipation fan 5 can also be installed on the side wall of the heat insulation cover 4, such as shown in Figure 5 , as long as the heat dissipation fan 5 can blow to the heat dissipation flow guide cavity 41 and the heat generating assembly 3.

[0032] Further, in order to facilitate the heat of the electrical device 6 to be quickly and efficiently conducted to the heat dissipation piece 62, the electrical device 6 is arranged in an arc shape in the electrical device assembly cavity 11.

[0033] The working principle of the embodiment is as follows:

[0034] In the embodiment, the heat insulation cover 4 is arranged between the shell 1 and the heat generating assembly 3, and the heat dissipation fan 5 blows to the heat dissipation flow guide cavity 41 when the electrical heating appliance is heated, so that the heat dissipation airflow flows to the outside through the air outlet 42, and the heat insulation cover 4 and the flowing heat dissipation airflow can effectively prevent the heat of the heat generating assembly 3 from being transmitted to the shell 1, thereby effectively reducing the temperature of the shell 1 and other electrical devices in the shell 1, improving the service life of the electrical heating appliance, facilitating the user to touch the shell to operate the electrical heating appliance, and improving the user experience.

[0035] Embodiment two: as shown in Figure 6As shown, the difference between the embodiment and the embodiment one is that the heat shield 4 is provided with a guide plate 44 corresponding to the air outlet 42, and the guide plate 44 is used to guide the air flow output from the air outlet 42 upward. By setting the guide plate 44, the heat dissipation air flow output from the air outlet 42 can be prevented from directly blowing on the user.

[0036] Embodiment three: as Figure 7 As shown, the difference between the embodiment and the embodiment two is that the heat shield 4 is provided with an inner groove 45 between the guide plate 44 and the air outlet 42.
