Referring to fig. 1-5, the preferred embodiment of the present invention is shown.

The utility model provides an electric toothbrush with a replaceable toothbrush head, which is not only limited to the electric toothbrush 10, but also can be used in other toothbrush products.

The electric toothbrush with the replaceable toothbrush head comprises a base 200 and the toothbrush head 100, wherein the toothbrush head 100 is movably connected with the base 200; a fixing column 201 extends in the base 200, the lower end of the fixing column 201 is fixedly connected with the vibrator, the upper end of the fixing column 201 is arranged in a vacant mode, a plurality of enclosing strips 202 are arranged around the fixing column 201 in a surrounding mode, two adjacent enclosing strips 202 are arranged at intervals, and an interval area 203 is arranged between the two adjacent enclosing strips 202; in the radial direction of toothbrush head 100, the interior of toothbrush head 100 has an open-mouthed mounting cavity, in which a plurality of protruding blocks 102 are arranged corresponding to the positions of spaced regions 203; when toothbrush head 100 is secured to base 200, securing posts 201 sink into the mounting cavities and projections 102 engage in corresponding spaced-apart regions 203.

Above-mentioned electric toothbrush of removable toothbrush head that provides, be swing joint between toothbrush head 100 and the base 200, when electric toothbrush 10 used for a relatively long time, when the effect worsens, can directly pull down toothbrush head 100 from base 200 and change and can continue to use to can effectively practice thrift electric toothbrush 10's use cost, have very strong practicality.

Moreover, the fixing of the toothbrush head 100 is realized by the fixing column 201 sinking into the mounting cavity and matching with the mounting cavity and the protrusion block 102 embedded into the corresponding spacing region 203, so that a better fixing effect is achieved.

The base 200 has a mounting area thereon, which is recessed toward the inside of the base 200.

A separation column 101 extends from the middle of the installation chamber, and the separation column 101 penetrates through the radial direction of the installation chamber and is arranged in a vacant way towards the direction of the base 200; the interior of the separation column 101 is hollow to form a first chamber 103, and a second chamber is formed by enclosing between the outer side wall of the separation column 101 and the inner side wall of the installation chamber; when toothbrush head 100 is fixed on base 200, the upper end of fixed column 201 is embedded into first cavity 103, and it is embedded into the second cavity to enclose strip 202, and like this, first cavity 103 and second cavity are independent arrangement, consequently at the in-process of block, can not mutual interference between first cavity 103 and the second cavity to all can independently realize the block effect to toothbrush head 100, increase the fault-tolerant rate in the electric toothbrush 10 use.

The convex block 102 is arranged in the second cavity in such a way, firstly, one end of the convex block 102 is connected with the outer side wall of the separation column 101, the other end of the convex block 102 is connected with the inner side wall of the installation cavity, the second cavity is separated into a plurality of independent cavities, when the toothbrush head 100 is fixed on the base 200, the convex block 102 is embedded into the corresponding spacing region 203, the enclosing strip 202 is embedded into the corresponding independent cavity, the plurality of independent cavities respectively realize the accommodation and the clamping of the plurality of enclosing strips 202, and the fault tolerance in the clamping process is further increased.

The upper end of the fixing column 201 is arranged in a flat shape, and the shape of the second cavity corresponds to the upper end of the fixing column 201, so that the sliding between the toothbrush head 100 and the base 200 during the use process can be effectively prevented, and the stability of the electric toothbrush 10 during the use process of a user can be enhanced.

In addition, the enclosing strip 202 includes a vertical wall having one end connected to the base 200 and the other end connected to the tilt arm, the vertical wall and the tilt arm being integrally formed and arranged, and the tilt arm being arranged to be inclined toward the fixing column 201, thereby facilitating the embedding of the enclosing strip 202 into the mounting chamber.

Furthermore, along deviating from the fixed column 201 direction, the lateral wall of enclosing strip 202 extends outwards and forms reinforcing wall 210, two adjacent enclosing strip 202 reinforcing walls 210 are parallel opposite arrangement, like this, when the protrusion piece 102 is embedded into corresponding interval region 203, the positive and negative both sides of protrusion piece 102 support respectively and press on the reinforcing wall 210 that is arranged opposite between adjacent enclosing strip 202, on the one hand carry out spacing fixed to protrusion piece 102, on the other hand, reinforcing wall 210 can also play the effect of reinforcing enclosing strip 202 intensity, in the process of combining repeatedly with protrusion piece 102, also can not take place the condition of buckling, distortion, thereby increase electric toothbrush 10's durability.

The reinforcing wall 210 is provided with a wear-resistant layer, and the surface of the wear-resistant layer is rough and is arranged in a rugged manner, so that the friction force between the reinforcing wall and the protruding block 102 can be increased.

The bottom of toothbrush head 100 is the flaring and arranges, on the one hand, conveniently encloses the insertion of closing strip 202 and fixed column 201, and on the other hand, the bottom of toothbrush head 100 has bigger area of contact with base 200, and then makes the combination between toothbrush head 100 and the base 200 more firm, and is also more convenient to toothbrush head 100's installation and dismantlement.

Be provided with sunken groove 211 on base 200, sunken groove 211 encircles and closes strip 202 and arrange, and when toothbrush head 100 was fixed on base 200, the bottom of toothbrush head 100 was embedded into sunken groove 211, and sunken groove 211 can play the effect of water-stop.

In order to further enhance the waterproof performance of the joint of the toothbrush head 100 and the base 200, a first waterproof rubber strip 212 and a second waterproof rubber strip 213 are arranged in the concave groove 211 along the circumferential direction of the concave groove 211, and the first waterproof rubber strip 212 and the second waterproof rubber strip 213 are respectively arranged at two sides of the lowest point of the concave groove 211 to form two waterproof lines.

Be provided with protruding platform 209 on base 200, a plurality of enclosing strip 202 of closing arrange on protruding platform 209, and sunken groove 211 encloses the periphery of closing the bottom at protruding platform 209, like this, even water has crossed first waterproof stripe 212 and second waterproof stripe 213, also can't cross protruding platform 209, and then can keep the drying of enclosing strip 202 of protruding platform 209 top for toothbrush head 100 is inseparabler with base 200's combination.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
