Description

Handle assembly and electric toothbrush of even leaded light of moulding plastics formula Technical Field The utility model relates to the technical field of electric toothbrushes, in particular to an injection molding type uniform light guide handle assembly and an electric toothbrush. Background Most conventional electric toothbrushes have only basic cleaning functions, and lack effective interaction with the user. The user is difficult to intuitively know important information such as the working time, the cleaning mode, the residual electric quantity and the like of the toothbrush in the using process. In recent years, in order to meet the demands of users for the diversity and the intellectualization of the functions of the electric toothbrushes, some electric toothbrushes with light interaction functions are appeared on the market. Chinese patent CN219184246U (publication date 2023, 6, 16) discloses a light structure of electric toothbrush, which sets several light emitting holes on the handle, and sets light isolating parts between adjacent light emitting holes, so that each light emitting hole forms independent light emitting area, and sets light emitting parts corresponding to the light emitting holes one by one in the handle, so as to realize man-machine interaction, and the user can clearly observe the light on the corresponding gear to light up, so as to know the working state of the toothbrush. However, the display mode of the lamplight in the technical scheme is single, information can be provided only by the on-off of the lamplight, and interaction experience with richer visual effects cannot be provided. Chinese patent CN109106460B (publication date 2023, 10, 27) discloses an electric toothbrush, which comprises a handle, a toothbrush head arranged on the handle, a light-transmitting part arranged on the wall of the handle, a signal indicator light corresponding to the light-transmitting part and a movement for driving the toothbrush head to vibrate or rotate arranged in the handle, wherein the light-transmitting part is prepared and obtained by a primary injection molding process and is connected with the handle by a secondary injection molding process, and a positioning part is arranged on the light-transmitting part and used for positioning the light-transmitting part in the process of the secondary injection molding process. In addition, the light-transmitting piece can be positioned in the process of the secondary injection molding process by arranging the positioning part on the light-transmitting piece, so that the secondary injection molding is convenient, and the production efficiency of the electric toothbrush is improved. The prior art mainly solves the problem that the electric toothbrush handle is easy to leak water due to the key and the lamplight, but the light transmittance and the lamplight uniformity are not introduced too much. In summary, although the existing electric toothbrush light interaction and sealing waterproof technology has advanced to some extent, there are a plurality of disadvantages, such as insufficient light interaction modes, limited display content and interaction functions, insufficient uniform light display, difficulty in providing more attractive and accurate information, and failure to fully satisfy the needs of users for the intelligent and individuation of the electric toothbrush. Therefore, there is a need for an improved light interaction and waterproofing technique for electric toothbrushes to overcome the shortcomings of the prior art and provide a better, more convenient use experience for users. Disclosure of utility model Aiming at the problems of insufficient light interaction modes, uneven light emission, water leakage easily caused by insufficient tightness of an operation panel and keys of the electric toothbrush in the prior art, the utility model provides an injection molding type handle assembly with uniform light guide and the electric toothbrush. The utility model is realized by the following technical scheme: The handle component comprises a handle shell, a panel component and a state light guide component, wherein the handle shell is provided with a switch piece, the panel component and the switch piece are arranged on the same side surface of the handle shell, and the state light guide component is arranged on the other side surface opposite to the panel component; The handle assembly further comprises a bottom cover and waterproof silica gel, the bottom cover is arranged at the bottom end of the handle shell, and the waterproof silica gel is abutted to the inner peripheral side of the handle shell through the bottom cover. So set up, waterproof silica gel passes through the extrusion effect of bottom, closely laminates in handle shell inner periphery side, fills the tiny gap between bottom and the handle shell, forms flexible seal barrier, even when electric toothbrush high frequency vibrations, still can keep the leakproofness
