Example 1
As shown in fig. 1, a structure of a replacement head for an electric toothbrush according to the present invention includes a tail cap 1, a motor 2, and a head body 3.
As shown in fig. 4, a schematic diagram of the motor structure is shown. The output end of the motor 2 is provided with a motor output shaft 201; the motor output shaft 201 is provided with a buckling point 202;
as shown in fig. 2, a schematic structural view of the tail cap is shown. The tail cap 1 includes a fixing portion 11, a stopper portion 12 connected to the fixing portion 11, and a socket portion 13 connected to the stopper portion 12.
The limiting part 12 comprises a first limiting ring 121 and a second limiting ring 122 arranged on the upper side of the first limiting ring 121, wherein the periphery of the second limiting ring 122 is uniformly provided with lugs 123, and in the embodiment, 4 lugs 123 are arranged. When the tail cover 1 is inserted into the brush head main body 3, the first limiting ring 121, the protruding block 123 and the inside of the brush head main body 3 are mutually extruded to generate larger friction force, so that the fixing function is realized.
The diameter of the fixing portion 11 is larger than that of the first stop collar 121, and the diameter of the first stop collar 121 is larger than that of the second stop collar 122. The diameter of each part is matched with the inner diameter of the large brush head body 3.
The plug section 13 comprises a first spring wall 16, a second spring wall 17 and a connecting piece 15. The other end of grafting portion 13 is connected with tail cap elastic wall 14, is provided with connecting block 15 between tail cap elastic wall 14 and the spacing portion 12, and connecting block 15 is provided with two recesses near the one end of tail cap elastic wall 14, is provided with second elastic wall 17 between two recesses, and the opposite side of second elastic wall 17 is provided with first elastic wall 16 on spacing portion 12, and grafting portion 13 inboard is provided with the grafting groove on the connecting block.
The motor output shaft 201 is placed in the insertion groove.
The first elastic wall 16 and the second elastic wall 17 are arranged relatively, elastic protruding points are arranged on the first elastic wall 16 and the second elastic wall 17, when the motor output shaft 201 is inserted into the tail cover 1, the motor output shaft 201 is preloaded by the elastic protruding points, and when the motor output shaft 201 is inserted, elastic deformation is generated, so that the purpose of fastening the output shaft is achieved. After the tail cap 1 is inserted into the brush head main body 3, the first elastic wall 16 and the second elastic wall 17 are extruded by the inner wall of the brush head main body 3, and further extrude the motor output shaft 201, so that the aim of secondarily fastening the output shaft is fulfilled.
As shown in fig. 3, a schematic structural view of the tail cap from another view angle is shown. The clamping block 18 is arranged on the opposite side of the first elastic wall 16 to the second limiting ring 122, the clamping block 18 is matched with the buckling point 202 on the motor output shaft 201, when the motor 2 is inserted into the inserting groove, the motor 2 outwards extrudes the clamping block 18, and when the motor 2 reaches a specified position, the clamping block 18 falls into the buckling point 202, so that the inserting stability is ensured.
As shown in fig. 5, a top view of the large body of the brush head is shown. Two first limit strips 301 matched with the grooves are arranged in the brush head body 3. When the tail cover 1 is inserted into the brush head main body 3, the two grooves on the tail cover 1 are inserted inwards along the two first limit strips 301, and at the moment, the first limit strips 301 play a guiding role on the tail cover 1. When the tail cover 1 is completely inserted into the brush head main body 3, the first limiting strip 301 can prevent the tail cover 1 from rotating, and at this time, the first limiting strip 301 plays a limiting role on the tail cover 1.
Two second limiting strips 302 are arranged above the first limiting strips 301 in the brush head main body 3, and the two second limiting strips 302 are symmetrically arranged. The distance between the two second limiting strips 302 is matched with the width of the motor output shaft 201, after the motor output shaft 201 is inserted, the motor output shaft 201 is pressed inwards, the purpose of fixing the motor output shaft 201 is achieved, and therefore the motor output shaft 201 is prevented from rotating during operation.
A third limiting bar 303 is arranged in the middle of the two second limiting bars 302 and inside the brush head main body 3, and the third limiting bar 303 is positioned on the opposite side of the first limiting bar 301. When the motor output shaft 201 is inserted, the third limiting bar 303 will prop against the top end of the motor output shaft 201 at the end near the tail cap 1, and limit the motor output shaft 201 in the longitudinal direction along the brush head main body 3.
The first limit bar 301, the second limit bar 302 and the third limit bar 303 are mutually matched, so as to achieve the purpose of fixing the tail cover 1 and the motor output shaft 201.
On the basis of the above, the elastic wall 14 of the tail cover can be further provided with a metal spring, the metal spring holds the elastic wall 14 of the tail cover, and the elastic structure of the metal spring and the elastic wall 14 of the tail cover are stacked together to achieve a fitting force to the output shaft 201 of the motor. When the tail cover 1 is arranged in the brush head large body 3, the metal elastic sheet and the brush head form resultant force to hold the motor output shaft 201, so that the purposes of force transmission and fastening of the motor output shaft 201 are achieved.
The metal spring sheet holds the tail cover elastic wall 14, so that the strength and durability of elastic deformation are improved.
Therefore, the electric toothbrush replacement head is provided with the metal elastic sheet, the motor output shaft is pressed by the continuous elastic force of the metal elastic sheet, and the gap formed by the fact that the tail cover and the brush head are greatly driven by inertia force to open and close the working matching surface by the high-frequency torsion of the motor output shaft is eliminated, so that redundant noise is absorbed, and the user experience is more comfortable; under the condition of full power, the vibration amplitude of the toothbrush head is large, the metal spring plate can absorb excessive or redundant energy in a vibration-damping way, so that the gum is prevented from generating a tingling sensation, the toothpaste is prevented from splashing, and the generated foam is prevented from splashing after the toothbrush is taken out of the oral cavity, so that the brushing experience is more comfortable; the first elastic wall and the second elastic wall are arranged, so that the service life of the brush head is longer compared with that of a replacement brush head made of pure plastic, the elastic compensation filling structure is used for filling the abrasion gap, and the poor experience of loud noise caused by the fact that the service life is fast used is avoided.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention and not for limiting it, and although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that: the technical scheme of the invention can be modified or replaced by the same, and the modified technical scheme cannot deviate from the spirit and scope of the technical scheme of the invention.
