[0014] Reference Figure 1-2 The utility model proposes a heated toilet seat with an overheating protection structure, comprising a toilet seat body 1, a heating cable 2, a circuit board 3, and a connecting piece 4. The heating cable 2 and the circuit board 3 are both installed on the toilet seat body 1, the connecting piece 4 and the heating cable 2 are electrically connected through a first connecting unit 5, the connecting piece 4 and the circuit board 3 are electrically connected through a second connecting unit 6, and a fuse 7 is installed on the connecting piece 4 and electrically connected to the first connecting unit 5 and the second connecting unit 6.

[0015] The fuse 7 is installed in the installation groove opened on the connecting member 4, and the two ends of the fuse 7 are respectively welded and electrically connected with the first connecting unit 5 and the second connecting unit 6. When in use, when the temperature inside the circuit is too high, the fuse 7 melts and disconnects the circuit to avoid safety accidents.

[0016] The heated toilet seat proposed in the utility model also includes a shell 8 and a cover plate 9. The shell 8 is fixed on the toilet seat body 1. The cover plate 9 is sealed on the opening of the shell 8 along a first direction and together with the shell 8 constitutes an assembly chamber for sealing the assembly of the circuit board 3. The shell 8 and the cover plate 9 are both provided with through holes arranged along the second direction. The connecting piece 4 can be inserted into the through hole along the second direction and fixedly connected to the shell 8 by screws.

[0017] During assembly, the circuit board 3 is sealed and assembled in the assembly room to isolate it from the external humid environment, thereby preventing the circuit board 3 from being in a humid environment for a long time and causing it to be damaged. This better protects the circuit board 3 and extends its service life. When a circuit failure occurs, it is only necessary to pull the connector 4 out of the through hole to replace the connector 4 (when the fuse 7 is blown) or to repair the circuit board 3, making the maintenance of the toilet seat easier and quicker.

[0018] In the above embodiments, specific reference is made to Figure 3 , in order to realize the electrical connection between the connector 4 and the heating cable 2 and the circuit board 3. The first connecting unit 5 includes a first pole piece 51 fixed on the connector 4 and a second pole piece 52 electrically connected to the output end of the heating cable 2 and fixed in the through hole. When the connector 4 is inserted into the through hole, the first pole piece 51 and the second pole piece 52 are in close contact and electrically connected.

[0019] The second connecting unit 6 includes a third pole piece 61 fixed on the connecting member 4 and a fourth pole piece 62 electrically connected to the circuit board 3 and fixed in the through hole. When the connecting member 4 is inserted into the through hole, the third pole piece 61 is electrically connected to the fourth pole piece 62 in abutting relationship, and the fuse 7 is electrically connected to the first pole piece 51 and the third pole piece 61.

[0020] In the above embodiment, there are two connecting members 4, and the distance between the two connecting members 4 decreases gradually from the outer end to the inner end, so that the connection between the cover plate 9 and the shell 8 is more secure.

[0021] The first pole piece 51 is fixed to the plug-in end of the connector 4 , the third pole piece 61 surrounds the connector 4 , and the mounting portion of the connector 4 for assembling the third pole piece 61 is in a truncated cone shape.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
