Referring to figs. 1 to Fig. 3, electric toothbrush provided in an embodiment of the present invention, including handle 10, the motor in handle 10
20, the transmission shaft 30 being installed on the output shaft of motor 20, and the brush head 40 being installed on transmission shaft 30.It is covered on transmission shaft 30
If a water proof ring 50, water proof ring 50 has opposite first end 51 and second end 52, and the first end 51 of water proof ring 50 is located at brush head
In 40, the second end 52 of water proof ring 50 is located in handle 10, and spring 60, water proof ring 50 are arranged in the first end 51 of water proof ring 50
On be also arranged with fastener 70, specifically, fastener 70 is sheathed in the first end 51 of water proof ring 50.Fastener 70 is fixed on biography
On moving axis 30 and water proof ring 50 is compressed, spring 60 is located between fastener 70 and the first end 51 of water proof ring 50.
In the present invention, the first end 51 and second end 52 of water proof ring 50 are respectively protruding into brush head 40 and handle 10, water proof ring
50 block the gap between handle 10 and brush head 40, to avoid in water stain entrance brush head 40 or handle 10, have good anti-
Water effect；Moreover, sheathed spring 60 in the first end 51 of water proof ring 50, by the spring 60 with elastic adjustment effect in radial direction
On water proof ring 50 is fixed, then further fixed by fastener 70, prevent water proof ring 50 from circumferentially rotating or moving axially,
The stability that water proof ring 50 is installed is improved, avoids rotating and failing with transmission shaft 30, improves the waterproof performance of electric toothbrush and make
Use the service life.
Further, referring to Fig. 3, Fig. 4, there is platform between the first end 51 of water proof ring 50 and the second end 52 of water proof ring 50
Terrace 53 is divided into the two parts being respectively arranged in brush head 40 and handle 10 by step surface 53.Fastener 70
With opposite first end 71 and second end 72, transmission shaft 30 is equipped with the first anti-skid structure, and the first end 71 of fastener 70 is solid
At the first anti-skid structure, the second end 72 of fastener 70 is resisted against on step surface 53.In this way, passing through the effect of fastener 70
Water proof ring 50 is secured firmly on transmission shaft 30, it is prevented to be rotated up in play or week in the axial direction.
Specifically, in the present embodiment, referring to Fig. 5 to Fig. 7, the first anti-skid structure includes the limit on 30 outer wall of transmission shaft
Position card slot 31,71 inner wall of first end of fastener 70 are equipped with the retention bead 73 that can be protruded into limit card slot 31.Pass through limit convex
The cooperation for playing 73 with limit card slot 31 increases frictional force between transmission shaft 30 and fastener 70, avoids circumferentially rotating.
Further, to keep antiskid effect more preferable, in the present embodiment, limit card slot 31 is set as two, and is oppositely arranged,
Correspondingly, retention bead 73 is also two, and is correspondingly arranged.Specifically, reference Fig. 6, Fig. 7,31 rectangular in cross-section of limit card slot,
Accordingly, 73 section of retention bead is also in rectangle.Certainly, retention bead 73 and limit card slot 31 or other shapes.
Certainly, in other embodiments, the first anti-skid structure can also use other structures.As the first anti-skid structure includes
External screw thread (not shown) on 30 outer wall of transmission shaft, the first end 71 of fastener 70 are equipped with the interior spiral shell cooperated with external screw thread
Line.By thread matching structure, it is also able to achieve being fixedly connected for fastener 70 and transmission shaft 30, and avoids that week occurs therebetween
To relative rotation or axially opposing movement.
Further, 30 outer wall of transmission shaft is equipped with annular slot 32, and 51 inner wall of first end of water proof ring 50 extends internally
Flange 54 is formed, flange 54 is arranged in annular slot 32, and the end of the first end 71 of fastener 70 reclines the of water proof ring 50
54 outer end of flange of one end 51.Water proof ring 50 is realized by the cooperation of flange 54 and annular slot 32 is tentatively fixed on transmission shaft
On 30, and fastener 70 is sheathed on 50 outside of water proof ring, and 54 outer end of flange is close in the end of the first end 71 of fastener 70,
The first end 51 of water proof ring 50 is preferably limited in the end of the first end 71 of fastener 70.
Further, it is equipped with connecting bracket 80 in brush head 40, is interference fitted between connecting bracket 80 and brush head 40.Transmission shaft
30 protrude into connecting bracket 80, and transmission shaft 30 is equipped with the second anti-skid structure far from the end of fastener 70.In this way, anti-by second
Slipped Clove Hitch structure realizes the fixation of transmission shaft 30 and connecting bracket 80, realizes being fixedly connected between transmission shaft 30 and brush head 40 indirectly.
Specifically, the second anti-skid structure includes the first limit plane 33 on 30 outer wall of transmission shaft, connecting bracket 80
It is interior to be equipped with the second limit plane 81 being bonded with the first limit plane 33.First limit plane 33 and the second limit plane 81 are point
The plane not formed by straight-cut on 30 outer wall of transmission shaft.The fitting of two planes avoids sending out between transmission shaft 30 and connecting bracket 80
Raw rotation.
Further, the first angled transition plane is equipped on transmission shaft 30 and positioned at the inner end of the first limit plane 33
34, connecting bracket 80 is interior to be equipped with the second angled transition plane 82 being bonded with the first angled transition plane 34.In this way, passing through
First angled transition plane 34 reclines with the second angled transition plane 82, can transmission shaft 30 during installation can preferably with connection
It is merged between bracket 80, avoids the occurrence of gap and shake；And angled transition plane is axially extending along transmission shaft 30, also enhances
Axial bonding strength.
Further, notch 35 is additionally provided on 30 outer wall of transmission shaft, being equipped in connecting bracket 80 can protrude into notch 35
Convex block 83, notch 35 are set to 34 back side of the first angled transition plane.Convex block 83 is stuck in in notch 35, connection is further enhanced
Bracket 80 and the axial bonding strength of transmission shaft 30, avoid the two that position occurs in the axial direction.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within principle.
