Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The electric toothbrush 1 in fig. 1 and 2 comprises a toothbrush body 100 and a toothbrush protection sleeve 200, the toothbrush protection sleeve 200 is detachably matched with the toothbrush body 100, the toothbrush body 100 comprises a brush head 110 and a handle 120, when the toothbrush protection sleeve 200 is sleeved on the toothbrush body 100 along the direction from the brush head 110 to the handle 120, the brush head 110 is wrapped by the toothbrush protection sleeve 200, and the handle 120 is at least partially exposed.

The basic structure of the inside of the electric toothbrush 1 of the present invention is described by taking the embodiment 1 in fig. 3 as an example, and fig. 3 is a cross-sectional view of the electric toothbrush along a-a in fig. 1. fig. 3 shows a handle 120 comprising a housing 121, a bracket 122 is disposed in the housing 121, the bracket 122 is mainly used for fixing a motor 123 and a power source 124, the motor 123 can generate vibration under the power supply of the power source 124, and the handle 120 transmits the vibration to the head 110.

For convenience of description, the present invention only shows the difference between the embodiments in the matching structure of the toothbrush body 100 and the toothbrush protection cover 200, and the electric toothbrushes in embodiments 2 and 3 described later also adopt the same basic structure, which is not described again. Of course, the motor 123 and the power source 124 in the toothbrush body 100 may be fixed separately, and are not limited to being fixed inside the same housing 121, nor to being fixed inside the housing 121 by the same bracket 122.

As shown in fig. 3, as an example of a structure of the toothbrush body 100 and the toothbrush protection cover 200 matching with each other, a magnet 125 is further disposed on the bracket 122, and correspondingly, a magnetizer 201 is disposed on the toothbrush protection cover 200, the magnetizer 201 may be made of ferromagnetic material such as iron, nickel, cobalt, etc., the magnetizer 201 may be placed by forming a groove on the toothbrush protection cover 200, or the toothbrush protection cover 200 and the magnetizer 201 may be integrally molded. Preferably, as shown in this embodiment, in order to improve the magnetic attraction force, the magnetizer 201 has a ring structure.

As a modification of embodiment 1 in FIG. 3, a magnet may be provided on the toothbrush protective cover 200 and a magnetizer may be provided in the case 121 of the toothbrush body 100; the toothbrush protective sleeve 200 can be provided with a groove for placing a magnet, and the toothbrush protective sleeve 200 and the magnet can be integrally molded; the magnetizer may be disposed on the bracket 122 or directly disposed on the casing 121, for example, wrapped on the inner wall of the casing 121, and both the magnetizer and the magnet adopt a ring structure to improve the magnetic attraction.

In short, the toothbrush protection cover 200 is detachably disposed on the toothbrush body 100 by magnetic attraction. Toothbrush protective sheath 200 and toothbrush body 100 set up through the cooperation of magnetism mode, the dimensional requirement of the internal diameter that has reduced toothbrush protective sheath 200 and the external diameter of toothbrush body 100, need not both closely to cooperate promptly, alright realize fixedly, simultaneously, the friction of toothbrush protective sheath 200 inner wall and toothbrush body 100 outer wall has been reduced, keep toothbrush body 100 pleasing to the eye, reduce wearing and tearing between the two, thoroughly solve between toothbrush protective sheath 200 and the toothbrush body 100 because of the not hard up problem that uses for a long time and lead to.

When the toothbrush body 100 and/or the toothbrush protection cover 200 are provided with asymmetric shapes or patterns, as shown in fig. 2, the opening of the toothbrush protection cover 200 is provided with a bevel, the position on the brush handle 120 near the bottom is also provided with a bevel, the toothbrush body 100 and the toothbrush protection cover 200 need to be matched and arranged at a certain fixed angle or within an angle range to better show the overall structure of the electric toothbrush 1, and the overall visual effect of the electric toothbrush 1 may be affected by random sleeving, therefore, the utility model discloses embodiment 1 is improved.

As shown in fig. 4, as an example of a matching structure of the toothbrush body 100 and the toothbrush protection cover 200, in the electric toothbrush 1 of embodiment 2, on the basis that the toothbrush protection cover 200 and the toothbrush body 100 are detachably disposed in a magnetic adsorption manner, the outer wall of the housing 121 is further provided with a positioning protrusion 126, the inner wall of the toothbrush protection cover 200 is provided with a positioning groove 202, the positioning protrusion 126 is matched with the positioning groove 202 in size, and only when the positioning protrusion 126 coincides with the positioning groove 202, the toothbrush protection cover 200 can be continuously sleeved on the toothbrush body 100 along the direction from the brush head 110 to the brush handle 120. Embodiment 2 by adding a positioning device, the toothbrush body 100 and the toothbrush protection cover 200 can be set at a specific angle or angle range.

As an example of the structure of the toothbrush body 100 and the toothbrush protection cover 200, fig. 5 is a cross-sectional view of the electric toothbrush along a-a in fig. 1, and the difference between the embodiment 1 and the embodiment 3 is that the toothbrush protection cover 200 and the toothbrush body 100 in the embodiment 1 (fig. 3) are magnetically attracted by the magnet and the magnetizer, and the toothbrush protection cover 200 and the toothbrush body 100 in the embodiment (fig. 5) are magnetically attracted by the magnet and the magnetizer. As shown in fig. 5, a first magnet 127 and a second magnet 128 are disposed on a bracket 122 in a toothbrush body 100, the first magnet 127 and the second magnet 128 are symmetrically disposed about a central axis X of the toothbrush body 100, the first magnet 127 and the second magnet 128 have opposite magnetism on a surface far from the central axis X, a third magnet 203 and a fourth magnet 204 are disposed on a toothbrush protection cover 200, the first magnet 127 and the second magnet 128 are symmetrically disposed about the central axis Y of the toothbrush protection cover 200, a magnetic pole (N-pole) of a surface of the third magnet 203 close to the central axis Y is opposite to a magnetic pole (S-pole) of a surface of the first magnet 127 far from the central axis X, a magnetic pole (S-pole) of a surface of the fourth magnet 204 close to the central axis Y is opposite to a magnetic pole (N-pole) of a surface of the second magnet 128 far from the central axis X, and by using the principle that like poles repel each other and opposite poles attract each other, when the toothbrush protection cover 200 is dislocated with the toothbrush body 100, the two pairs of magnets on the toothbrush protection cover 200 and the toothbrush body 100 drive the toothbrush protection cover 200 to rotate to an angle or an angle range matched with the toothbrush body 100 to attract each other due to the action of the magnetic field. In order to improve the magnetic attraction force, the third magnet 203 and the fourth magnet 204 may adopt a "C" type structure. The two magnets in the toothbrush body 100 may be directly disposed on the housing 121.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
