[0024] In order to make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0025] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplification, the components and arrangements of the specific examples are described in the following. Of course, they are only examples and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to the numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements discussed.

[0026] For the convenience of description, spatial relative terms can be used in the text to describe the relative position relationship or movement condition of one element or feature with respect to another element or feature as shown in the figure, such as "internal", "external", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure is flipped over or the posture is changed or the movement condition is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both the up and down positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0027] In order to solve the technical problem that the existing technology cannot timely detect the temperature abnormality of the heating body due to slow air circulation, and thus fails to take safety protection measures in time, the application provides a forwardly placed heating body circuit breaking protection structure, which can realize that the heating body is directly opposite the air outlet of the air outlet part, and is arranged between the air outlet part and the circuit breaking protection structure, so that when the air outlet part blows air on the heating body, the heating body performs normal heat dissipation work, and at the same time, the air outlet part blows air directly on the circuit breaking protection structure, which is beneficial to the circuit breaking protection structure to timely sense the temperature change of the heating body, and to timely break the circuit when the temperature of the heating body abnormally rises, which is beneficial to avoid damage of the heating body due to continuous overheating work, to avoid melting of the surrounding structure due to high temperature, and to reduce maintenance cost and improve the service life of the product.

[0028] Figs. 1-2 The forwardly placed heating body circuit breaking protection structure provided by the application includes a connecting shell 1, an air outlet part 2, a heating body 3, and a circuit breaking protection structure 4. The heating body 3 is connected with the circuit breaking protection structure 4, is arranged opposite the air outlet of the air outlet part 2, and is arranged between the air outlet part 2 and the circuit breaking protection structure 4. The heating body 3 is arranged apart from the circuit breaking protection structure 4. The air outlet part 2, the heating body 3, and the circuit breaking protection structure 4 are all arranged in the connecting shell 1. The connecting shell 1 is arranged to protect the air outlet part 2, the heating body 3, and the circuit breaking protection structure 4 from scratches by external objects, which is beneficial to reduce the possibility of damage of the product due to scratches. The air outlet part 2 is arranged to generate air and perform blowing work. The heating body 3 is arranged to generate heat and cooperate with the air outlet part 2 to blow hot air. The circuit breaking protection structure 4 is arranged to monitor the temperature of the heating body 3 in real time when the heating body 3 works, and to disconnect the circuit to perform safety protection when detecting abnormal temperature of the heating body 3.

[0029] Preferably, the heating body 3 of the application is a PTC heating body 3 structure, which has the characteristics of positive temperature resistance coefficient and automatic temperature control, and the advantage of high efficiency. The air outlet part 2 in the application is a blower, but is not limited thereto, and can also be a fan, which can be arranged according to actual needs. Preferably, the distance between the heating body 3 and the circuit breaking protection structure 4 is 10-15 mm, which maintains a reasonable gap, so as not to be too small to facilitate the smooth passage of air, and not to be too large to increase the overall size of the product.

[0030] In the present application, the circuit breaking protection structure 4 comprises a temperature breaker (not shown in the figure) and a fuse (not shown in the figure), one end of the heat generating body 3 is connected with the temperature breaker, the other end is connected with the fuse, and the temperature breaker is connected with the fuse. The temperature breaker disconnects the circuit connection when detecting that the temperature of the heat generating body 3 is too high, so that the heat generating body 3 stops working, and the fuse is fused to cut off the circuit when detecting that the temperature of the heat generating body 3 is too high, which is a double protection, which is beneficial to improve the accuracy of the circuit breaking, and when one of them fails to work, the other can also work normally, which is beneficial to improve the safety factor.

[0031] Please refer to Fig. 2 The heat generating body circuit breaking protection structure placed in the forward direction further comprises a fixed support 5, the heat generating body 3 is arranged in the fixed support 5, and the circuit breaking protection structure 4 is connected to one end of the fixed support 5. The fixed support 5 is arranged to provide a relatively fixed structure for the circuit breaking protection structure 4 and the heat generating body 3, avoiding the possibility of unstable structure connection, easy to be blown and fallen due to independent arrangement of each part; preferably, the fixed support 5 is a frame structure, i.e. a structure without plate material on the outside, avoiding the situation that part of the heat generating body 3 is blocked and the heat cannot be blown out, and the temperature reaching the circuit breaking protection structure 4 is inaccurate.

[0032] Please refer to Figs. 1-2 An air outlet 6 is arranged at one end of the connecting shell 1, the air outlet of the air outlet part 2 corresponds to the air outlet 6, and the fixed support 5 is arranged between the air outlet part 2 and the air outlet 6 and is fixed with the connecting shell 1. Preferably, the air outlet 6 is in a mesh structure and has a plurality of air outlet small holes 7, which has the advantage of relatively soft air outlet and can also reduce the possibility of being scalded by easily placing the hand of the user.

[0033] The present application also provides a heating type electric appliance comprising the heat generating body circuit breaking protection structure placed in the forward direction.
