[0020] like Figure 1 Figure 2 and Figure 3 As shown, the present invention provides a heatable electric toothbrush, comprising an electric toothbrush 1, a cover 5, and a connecting plate 4. The cover 5 is fitted over the bristles of the electric toothbrush 1, and a low-temperature heating element is installed inside the cover 5. One end of the cover 5 is provided with a vent hole 6. An axial channel 2 is provided on the outer wall surface of the electric toothbrush 1, and one end of the channel 2 is enlarged to form a storage groove 3. A locking component for positioning the cover 5 is provided in the storage groove 3. A connecting plate 4 is installed at one end of the cover 5, and the other end of the connecting plate 4 extends into the channel 2 and is movably connected to the channel 2.

[0021] In this embodiment, the locking assembly includes a rod 7, a compression spring, and a push plate 8. A through groove is provided on the side of the storage slot 3 away from the bristles. One end of the rod 7 is inserted into the through groove and a compression spring is installed thereon. The other end of the compression spring is installed on the inner wall of the through groove. The other end of the rod 7 extends into the storage slot 3 and is fixedly connected to the push plate 8. One end of the push plate 8 extends to the outside and is bent to form a pushing part. The inner side of the pushing part is in contact with the electric toothbrush 1. A space is formed between the pushing part and the groove for the rod to retract, so that the rod can be smoothly moved out of the vent hole.

[0022] In this embodiment, the cross-section of the insertion rod 7 located at one end inside the through groove is rectangular, and the cross-section of the through groove is also rectangular. The cross-section of the insertion rod 7 located at one end inside the groove is circular and matches the inner diameter of the vent hole 6. The rectangular structure can position the insertion rod so that the insertion rod can only move along the axial direction of the through groove, thus avoiding the rotation of the insertion rod and the push plate.

[0023] In this embodiment, shaft holes 12 are provided on both sides of the channel 2, and shaft rods are installed on both sides of the connecting plate 4. The other end of the shaft rods is inserted into the shaft hole 12 and a torsion spring is installed on each shaft rod. The other end of the torsion spring is fixedly connected to the inner wall of the shaft hole 12. The torsion spring can automatically lift the connecting plate and the cover, so that the cover can automatically cover the outside of the bristles.

[0024] In this embodiment, a wiring groove 10 is provided at one end of the channel 2. A wiring hole 11 communicating with the inner cavity of the electric toothbrush 1 is provided on the inner wall of the wiring groove 10. A wire is connected to the low-temperature heating element. The wire passes through the inside of the connecting plate 4 and extends along the wiring groove 10 and the wiring hole 11 to the inside of the electric toothbrush 1 and connects to the main control board of the electric toothbrush 1. A button 9 for controlling the start and stop of the low-temperature heating element is installed on the outer wall of the electric toothbrush 1. The low-temperature heating element can automatically limit the current and temperature and has the advantages of constant temperature heating, long natural life, energy saving, no open flame, and good safety performance.

[0025] As attached Figure 4 As shown, when the bristles are needed, the connecting plate and the cover can be rotated around the shaft until the connecting plate enters the channel and the cover enters the storage slot. Before the cover enters the storage slot, the push plate can push the insert rod to retract it. After the cover enters the storage slot, the push plate can be released, and the spring can push the insert rod outward to insert it into the vent hole, thereby positioning the cover on the electric toothbrush.

[0026] Conversely, after brushing, the insert can be pushed again using the push plate to pull it out of the vent. Once the insert is no longer in place, the torsion spring will rotate the shaft and connecting plate. The rotation of the connecting plate will then rotate the cover until it covers the bristles. At this point, the low-temperature heating element can be activated by pressing a button. The heat generated by the low-temperature heating element will dry the bristles to prevent bacterial growth. The cover will also minimize contact between dust and the bristles, ensuring their cleanliness.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
