Detailed description of the invention

For the ease of understanding this utility model, below with reference to relevant drawings, this utility model is described more fully。Accompanying drawing gives preferred embodiment of the present utility model。But, this utility model can realize in many different forms, however it is not limited to embodiment described herein。On the contrary, the purpose providing these embodiments is to make the understanding to disclosure of the present utility model more thorough comprehensively。

It should be noted that be referred to as " being fixed on " another element when element, it can directly on another element or can also there is element between the two。When an element is considered as " connection " another element, it can be directly to another element or may be simultaneously present element between the two。

Unless otherwise defined, all of technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model are generally understood that。The purpose describing specific embodiment it is intended merely to herein, it is not intended that in restriction this utility model at term used in the description of the present utility model。Term as used herein " and/or " include the arbitrary and all of combination of one or more relevant Listed Items。

Refer to Fig. 1, the electric toothbrush head of the first embodiment of this utility model electric toothbrush includes brush main body 10, drive link 30, poke rod 50 and plants mao part 70, cavity 102 it is provided with in brush main body 10, and brush main body 10 one end offers the opening 104 connected with cavity 102, poke rod 50 is connected to drive link 30, and drive link 30 and poke rod 50 are located in the cavity 102 of brush main body 10。Seeing also Fig. 2, plant mao part 70 one end and be provided with buckle 702, brush main body 10 is provided with holding section 106, plants mao part 70 one end and stretches into brush main body 10 from the opening 104 of brush main body 10 and the holding section 106 by buckle 702 with brush main body 10 is connected。Poke rod 50 with plant mao part 70 and coordinate and plant mao part 70 move to stir in the process that drive link 30 drives poke rod 50 to rotate。Planting mao part 70 and be provided with bristle 701, in the motor process planting mao part 70, tooth is cleaned by bristle 701。

In this electric toothbrush head, drive poke rod 50 to rotate by drive link 30, plant mao part 70 move thus stirring, simple in construction；And be connected by the holding section 106 of buckle 702 with brush main body 10 owing to planting mao part 70, firmly can be connected to brush main body 10 by planting mao part 70, it is to avoid plant mao part 70 and fly out in high-speed motion, so that use safety and reliability。

Referring to Fig. 3 and Fig. 4, one end of poke rod 50 is provided with biasing post 502, plants and offers the mating groove 704 holding biasing post 502 on mao part 70。When poke rod 50 rotates with drive link 30, owing to biasing post 502 is provided off, make the cell wall of the opposite sides of biasing post 502 reciprocating collision mating groove 704, so that planting mao part 70 to carry out back rotation。In the present embodiment, referring to Fig. 6, the rotation angle range planting mao part 70 is positive and negative 33.5 °。The rotation angle range planting mao part 70 is determined by position and the size of biasing post 502, and this rotation angle range can specifically be arranged according to actual needs。

Stirring and plant mao part 70 for realizing biasing post 502 and move, biasing post 502 may be configured as cam face, it is possible to is set to rotate the cylindric of eccentric shaft relative to poke rod 50, only needs the geometric center of biasing post 502 and the rotation eccentric shaft of poke rod 50 to arrange。In the present embodiment, biasing post 502 is cylindric, and the rotation eccentric shaft of its center and poke rod 50 is arranged。

Specifically, mating groove 704 can directly be opened in plants on mao part 70, also mao part 70 can also set up two projections 706 planting, mating groove 704 is surrounded by two projections 706, both mao part 70 can also offer groove planting, being also provided with two projections 706, two projections 706 lay respectively at groove both sides, are collectively forming mating groove 704。More specifically, protruding 706 is taper, and it is gradually reduced from bottom to top。

Referring to Fig. 5, plant and be further opened with stopper slot 708 on mao part 70, the holding section 106 of bristle body 10 is positioned at this stopper slot 708, so that stopper slot 708 limits the holding section 106 anglec of rotation in stopper slot 708, and then limits the rotation angle range planting mao part 70。The rotation angle range planting mao part 70 can be played restriction effect more accurately by stopper slot 708, the length of stopper slot 708 determines the rotation angle range planting mao part 70, that is, when biasing post 502 arrange the rotation angle range allowing to plant mao part 70 be positive and negative 36 degree time, can pass through arranging of stopper slot 708 further its rotation angle range is defined to positive and negative 33.5 °。Specifically, planting and offer two stopper slots 708 on mao part 70, two holding sections 106 coordinate with two stopper slots 708 respectively。

Specifically, stopper slot 708 is disposed adjacent with buckle 702, and the holding section 106 of bristle body 10 coordinates with buckle 702 and stopper slot 708 simultaneously。

Electric toothbrush head also includes drive sleeve 90, and drive sleeve 90 is fixed in the cavity 102 of bristle body 10, and poke rod 50 penetrates rotatably drive sleeve 90。Drive sleeve 90 and bristle body 10 form zero assembling and location, and play bearing effect。

This utility model also provides for a kind of electric toothbrush, and including motor and above-mentioned electric toothbrush head, motor is connected with drive link 30 to drive drive link 30 to rotate。

Embodiment described above only have expressed several embodiments of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims。It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model。Therefore, the protection domain of this utility model patent should be as the criterion with claims。
