Detailed Description

Before the embodiments are described in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. The utility model discloses can be the embodiment that other modes realized. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of "including," "comprising," "having," and the like, herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. In particular, when "a certain element" is described, the present invention is not limited to the number of the element being one, and may include a plurality of the elements.

As shown in fig. 1-4, the present invention provides an electric toothbrush 10 with shock-absorbing function, the electric toothbrush 10 includes a handle 12 and a shock-absorbing head installed at one end of the handle 12, the handle 12 is used for holding and controlling the user, and the handle 12 can drive the shock-absorbing head to vibrate for cleaning teeth. More specifically, a motor is provided within the handle 12, the motor having a drive shaft 14, one end of the drive shaft 14 extending out of the handle 12 for driving connection with the shock absorbing brushhead. The handle 12 is further provided with a switch button 16, and the switch button 16 is used for controlling the start and stop of the electric toothbrush 10.

The vibration-damping brush head comprises a brush head part 18, a fixing part 20 and an adjusting part 22 positioned between the brush head part 18 and the fixing part 20. The brush head 18 includes a base 24 and bristles 26 disposed on one side of the base 24, the adjusting portion 22 is disposed between the bottom of the base 24 and the top of the fixing portion 20, and the fixing portion 20 is provided with a driving connecting portion for connecting with a driving mechanism to be driven by the driving mechanism to generate vibration. In this embodiment, the driving connection portion is implemented as a driving hole 30 disposed at the bottom of the fixing portion 20, the driving mechanism is a motor inside the handle 12, and the driving shaft 14 is inserted into the driving hole 30 to drive the fixing portion 20 to vibrate.

The adjustment portion 22 is used to adjust the vibration intensity of the brush head portion 18 so that the vibration intensity of the brush head portion 18 is smaller than that of the fixing portion 20. The vibration strength may include vibration frequency, vibration strength, and other factors that affect the vibration strength, and is not specifically limited herein. Specifically, the base 24 and the fixing portion 20 are made of a first material, and the regulating portion 22 is made of a second material, the hardness of the first material being set to be greater than that of the second material. Since the hardness of the adjusting portion 22 is less than the hardness of the other two portions, the vibration intensity from the driving shaft 14 can be adjusted by the adjusting portion 22, so that the vibration intensity of the fixing portion 20 and the brush head portion 18 is inconsistent, that is, the vibration intensity of the brush head portion 18 is less than that of the fixing portion 20, thereby achieving the function of shock absorption.

Further, the second material is an elastic soft material, so that the adjusting portion 22 has an elastic deformation function. Because the hardness of the adjusting portion 22 is small, when the user operates improperly, for example, the holding force is suddenly increased, the adjusting portion 22 can elastically deform to alleviate the influence of improper use by the operator.

The base 24, the adjusting portion 22 and the fixing portion 20 may be integrally formed or fixed, for example, integrally formed by two-shot molding, or fixed by adhesive or the like. After installation, the two ends of the adjusting part 22 abut against the bottom of the base 24 and the top of the fixing part 20 respectively, and the adjusting part 22 is in smooth transition connection with the base 24 and the fixing part 20.

In the embodiment shown in fig. 1-2, the adjustment portion 22 is connected between the base 24 and the fixation portion 20 by means of an adhesive.

In the embodiment shown in fig. 3-4, the base 24 and the fixing portion 20 are connected and fixed by a connecting rod 32, and the adjusting portion 22 is sleeved on the connecting rod 32. For example, a through hole 34 adapted to the connecting rod 32 for the connecting rod 32 to pass through is disposed at a central position of the adjusting portion 22, the adjusting portion 22 is sleeved on the connecting rod 32 through the through hole 34, and upper and lower ends of the adjusting portion 22 are respectively abutted against ends of the base 24 and the fixing portion 20.

It should be noted that in the present embodiment, the shock absorbing brush head is applied to the electric toothbrush 10, but the present invention is not limited thereto, and in other embodiments, the shock absorbing brush head can be applied to other products having a driving mechanism and driving the shock absorbing brush head to vibrate.

The concepts described herein may be embodied in other forms without departing from the spirit or characteristics thereof. The particular embodiments disclosed should be considered illustrative rather than limiting. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. Any changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
