[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] Please refer to Figure 1-5 ;

[0026] The visualized light timing reminder device described in the utility model is applied to an electric toothbrush. It can be a device independent of the electric toothbrush or a part of the electric toothbrush, which will be explained below.

[0027] Specifically, it includes a fixed shell 1, a lamp ring 21 is embedded outside the fixed shell 1, and the lamp ring 21 and the fixed shell 1 are respectively provided with coaxial mounting holes 3, and a plurality of light guide walls 22 are arranged at intervals inside the fixed shell 1, one end of the light guide wall 22 is connected to the lamp ring 21, and a lamp board 41 is arranged below the other end, and a plurality of lamp beads 42 on the lamp board 41 correspond to the light guide walls 22 respectively. In this embodiment, one light guide wall 22 can correspond to one lamp bead 42, or one light guide wall 22 corresponds to a plurality of lamp beads 42, and the same technical effect can be achieved; in this embodiment, the number of light guide walls 22 is four, that is, the lamp ring 21 is divided into four parts, and the lamp board 41 is also electrically connected to a plurality of timers, and the timers also have four, which correspond to the lighting actions of different lamp beads 42, and each timer is preset with a time before leaving the factory. It should be noted that it should also include a controller and a switch for starting and closing the timer;

[0028] Preferably, both sides of the light guide wall 22 gradually expand from bottom to top, that is, both sides of the light guide wall 22 are inclined surfaces, and gradually become larger from the position close to the lamp beads 42 toward the lamp ring 21, which can better receive and transmit light, and make the corresponding part of the lamp ring 21 illuminated and guide light evenly.

[0029] The oral cavity is divided into four areas. Assuming that the working time of each area is the same, each lamp bead 42 lights up corresponding to the working time of one area. When in use, the timer is started by the switch to light up one of the lamp beads 42. The light of the lamp bead 42 is transmitted to the lamp ring 21 through the corresponding light guide wall 22 and is seen by the user. It should be noted that cross-lighting may occur, but the position of the lamp ring 21 corresponding to the luminous lamp bead 42 will be particularly bright; at the same time, the electric toothbrush is started to clean one of the areas in the oral cavity. When the cleaning time is up, the timer is turned off and another timer is turned off. Start, that is, one lamp bead 42 is continuously lit, and the next lamp bead 42 next to it is also lit. At this time, the area where two consecutive areas in the lamp ring 21 are lit, it means that the cleaning time of the first area is completed, and the second area of ​​the cavity should be cleaned. In this way, as the working time accumulates, the third area and the fourth area of ​​the lamp ring 21 are lit in turn. When the entire circle of the lamp ring 21 is lit, it means that the brushing time is over. The visual light timing prompt method can give users a better understanding of cleaning the cavity, avoid damaging the gums due to too long cleaning time in a certain area, and improve the product experience;

[0030] Furthermore, when the next area of ​​the light ring 21 is lit, a sound reminder and / or short vibrations of different frequencies can be provided, thereby realizing a multi-dimensional visual, auditory and tactile reminder for the user. When the entire circle of the light ring 21 is lit, a special sound reminder and vibrations of different frequencies are provided, indicating that the work is about to be completed.

[0031] The sound reminder requires the use of a speaker, while the vibration reminder requires the use of a vibration motor, and the speaker and the vibration motor should be electrically connected to the controller;

[0032] Of course, the above is only one implementation method of the light ring 21 and the timer. There are more usage combinations that can be made by using the cooperation between the light ring 21 and the timer, such as switching between lighting and extinguishing, so it should not be used as a limitation of the protection scope.

[0033] When the device is independent of the electric toothbrush, the fixed shell 1 is an independent entity, and the light ring 21 and the fixed shell 1 are respectively provided with coaxial mounting holes 3. At this time, the aperture of the coaxial mounting hole 3 is relatively large, and the electric toothbrush can be inserted therein from the bottom or top, so that the old style electric toothbrush can be equipped with a timing function without taking up space.

[0034] When the device is a part of an electric toothbrush, the fixed shell 1 is the outer shell of the electric toothbrush, the coaxial mounting hole 3 is formed for the output end of the motor to pass through, and the controller and the switch are shared with the electric toothbrush. When the electric toothbrush is started, the timer is turned on, and all timers are reset every time it is turned off;

[0035] In addition, a bracket 51 for fixing the motor is installed in the housing, and the lamp board 41 is installed on the bracket 51, making the overall structure more compact.

[0036] One embodiment of the fixed shell 1 of the utility model specifically includes a shell body 11 and a top cover 12, a lamp ring 21 is located between the shell body 11 and the top cover 12, and the top cover 12 covers the upper end surface of the lamp ring 21, which can avoid the lamp ring 21 from leaking light from above, so that the lamp ring 21 can only be displayed from the side, and a plurality of limiting grooves 13 adapted to the light guide wall 22 are provided in the shell body 11, and the light guide wall 22 is fixed by the limiting grooves 13, that is, the position of the lamp ring 21 is fixed, and each light guide wall 22 is separated independently by the limiting grooves 13, which can avoid the light of the lamp bead 42 from being transmitted to the adjacent light guide wall 22, thereby avoiding the occurrence of cross-lighting.

[0037] In addition, the light ring 21 is provided with a light-isolating groove 23 between two adjacent light-guiding walls 22, and a plurality of fixing ribs 14 are provided in the fixed shell 1 corresponding to the position of the light-isolating groove 23. The setting of the light-isolating groove 23 can also separate the two adjacent light-guiding walls 22 to avoid the occurrence of light crosstalk, and the setting of the fixing ribs 14 can fix the light ring 21. Of course, the light-isolating groove 23 and the limiting groove 13 can be set at the same time. Combined with the fixing ribs 14, the light ring 21 can be further fixed, and at the same time, a better light-isolating effect can be achieved to avoid the occurrence of light crosstalk.

[0038] This embodiment is based on an electric toothbrush. A fixing block 53 is installed at the output shaft 52 of the motor. The fixing block 53 is placed in the mounting hole 3 and is fixedly connected to the top cover 12 to achieve a waterproof sealing effect.

[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
