与现有技术相比，本发明的有益效果为：Compared with the prior art, the beneficial effects of the present invention are:
本发明将紫外线消毒灯置于刷盖内，采用刷盖作为消毒用的空腔，既可以保护刷头又可以起到消毒作用，而且实现了牙刷消毒盖体由牙刷主体供电的共享电源的创新。In the invention, the ultraviolet disinfection lamp is placed in the brush cover, and the brush cover is used as a cavity for disinfection, which can not only protect the brush head but also play a role in disinfection, and realizes the innovation of the shared power supply in which the toothbrush disinfection cover body is powered by the toothbrush main body. .
。采用弹簧作为导线，且对金属顶针产生向外弹力，有利于取电接点与供电接点之间保护良好的电性接触。. The spring is used as the wire, and the metal thimble generates outward elastic force, which is beneficial to the well-protected electrical contact between the power-taking contact and the power-supplying contact.
刷盖在桶状本体内进一步采用弹簧支架，有助于对弹簧的安装，也有益于刷盖的安装，弹簧支架进一步形成导向面，在将刷头装入刷盖内时，能导向作用。The brush cover further adopts a spring bracket in the barrel body, which is helpful for the installation of the spring and the installation of the brush cover. The spring bracket further forms a guide surface, which can guide the brush head when the brush head is installed in the brush cover.
UV控制板的安装成与刷盖成为斜面的位置，且将紫外线消毒灯在近于刷头的位置，可以最大范围地照到整个刷头，而不需要对LED发光体的光线进行大角度的扩散，降低了对LED发光体前端镜头的要求，也即降低紫外线消毒灯的性能要求，进而降低成本。且将紫外线消毒灯装于端盖，刷头不会接触到，避免了不当操作时，刷头对消毒灯的破坏作用。The UV control board is installed in a position where it is inclined to the brush cover, and the ultraviolet disinfection lamp is placed close to the brush head, which can illuminate the entire brush head to the greatest extent, without the need for a large angle of the light of the LED illuminator. Diffusion reduces the requirements for the front-end lens of the LED illuminator, that is, the performance requirements of the ultraviolet disinfection lamp, thereby reducing the cost. Moreover, the ultraviolet disinfection lamp is installed on the end cover, and the brush head will not touch, which avoids the damage of the brush head to the disinfection lamp when improperly operated.
因为UV控制板的斜装需求，端盖外端、桶状本体的外端均成为斜面，对刷头装入刷盖时，进一步给使用者一个清晰的指引作用。Due to the oblique installation requirements of the UV control board, the outer end of the end cap and the outer end of the barrel-shaped body are both inclined surfaces, which further gives the user a clear guidance when the brush head is installed in the brush cover.
端盖与桶状本体采用了轴向配合的定位安装，且采用卡扣联接，易于安装，又不影响外观。The end cover and the barrel-shaped body adopt the positioning and installation of axial matching, and adopt the snap connection, which is easy to install and does not affect the appearance.

The disinfection lamp is turned on, and the ultraviolet disinfection lamp starts to work after it is powered on. The UV control board is equipped with a delay circuit. When the ultraviolet disinfection lamp starts to work and the set time is reached, the power supply of the ultraviolet disinfection lamp is interrupted, and the disinfection work ends. Generally, the set time is 60 seconds, and it can also be 45 seconds, 75 seconds, or 90 seconds. In order to meet the requirements of different environments such as different regions and different temperatures, further innovations can be made. There is a knob on the end cover, and a potentiometer that can adjust the set time on the UV control board. The knob is connected with the potentiometer to achieve Adjustment of the set time.
本发明还可以提供一种刷盖产品结构的创新，即，一种消毒型刷盖结构，它的结构为：在刷盖内设有紫外线消毒灯，刷盖内壁设有与紫外线消毒灯 电性连接的导线，及位于刷盖外端且与导线相连的取电接点；与刷盖相联接的牙刷本体内设有电源，从牙刷本体一端向外延伸出的刷头，所述牙刷本体近刷头的一端设有与取电接点对应的供电接点；所述供电接点与牙刷本体内的电源连接。更进一步的具体结构参见上述各个实施例，在此不做赘述。它可以与电动牙刷的牙刷本体联接，也可以与非电动牙刷的牙刷本体联接。The present invention can also provide an innovation in the product structure of the brush cover, that is, a disinfection type brush cover structure. A connected wire, and a power-taking contact located at the outer end of the brush cover and connected to the wire; a power supply is provided in the toothbrush body connected with the brush cover, and a brush head extending outward from one end of the toothbrush body, the toothbrush body is close to the brush One end of the head is provided with a power supply contact corresponding to the power supply contact; the power supply contact is connected with the power supply in the toothbrush body.

综上所述，本发明将紫外线消毒灯置于刷盖内，采用刷盖作为消毒用的空腔，既可以保护刷头又可以起到消毒作用。采用弹簧作为导线，且对金属顶针产生向外弹力，有利于取电接点与供电接点之间保护良好的电性接触。To sum up, in the present invention, the ultraviolet disinfection lamp is placed in the brush cover, and the brush cover is used as a cavity for disinfection, which can not only protect the brush head but also play a role in disinfection. The spring is used as the wire, and the metal thimble generates outward elastic force, which is beneficial to the well-protected electrical contact between the power-taking contact and the power-supplying contact.
刷盖在桶状本体内进一步采用弹簧支架，有助于对弹簧的安装，也有益于刷盖的安装，弹簧支架进一步形成导向面，在将刷头装入刷盖内时，能导向作用。The brush cover further adopts a spring bracket in the barrel body, which is helpful for the installation of the spring and the installation of the brush cover. The spring bracket further forms a guide surface, which can guide the brush head when the brush head is installed in the brush cover.
UV控制板的安装成与刷盖成为斜面的位置，且将紫外线消毒灯在近于刷头的位置，可以最大范围地照到整个刷头，而不需要对LED发光体的光线进行大角度的扩散，降低了对LED发光体前端镜头的要求，也即降低紫外线消毒灯的性能要求，进而降低成本。且将紫外线消毒灯装于端盖，刷头不会接触到，避免了不当操作时，刷头对消毒灯的破坏作用。The UV control board is installed in a position where it is inclined to the brush cover, and the ultraviolet disinfection lamp is placed close to the brush head, which can illuminate the entire brush head to the greatest extent, without the need for a large angle of the light of the LED illuminator. Diffusion reduces the requirements for the front-end lens of the LED illuminator, that is, the performance requirements of the ultraviolet disinfection lamp, thereby reducing the cost. Moreover, the ultraviolet disinfection lamp is installed on the end cover, and the brush head will not touch, which avoids the damage of the brush head to the disinfection lamp when improperly operated.
因为UV控制板的斜装需求，端盖外端、桶状本体的外端均成为斜面，对刷头装入刷盖时，进一步给使用者一个清晰的指引作用。Due to the oblique installation requirements of the UV control board, the outer end of the end cap and the outer end of the barrel-shaped body are both inclined surfaces, which further gives the user a clear guidance when the brush head is installed in the brush cover.
端盖与桶状本体采用了轴向配合的定位安装，且采用卡扣联接，易于安装，又不影响外观。The end cover and the barrel-shaped body adopt the positioning and installation of axial matching, and adopt the snap connection, which is easy to install and does not affect the appearance.
采用的图案光栅能起到导光作用，对使用者起到提示作用。为了透光至外部，端盖采用有部分透明率的材料。The adopted pattern grating can play a light guiding role and play a prompting role to the user. In order to transmit light to the outside, the end caps are made of materials with partial transparency.
刷盖与牙刷本体采用卡扣式联接，能快速固定刷盖，为使用者节约时间。The brush cover and the toothbrush body adopt a snap-type connection, which can quickly fix the brush cover and save time for the user.
本发明的消毒方法，是在UV控制板上设有定时电路，紫外线消毒灯开始工作时就进行计时，到达设定时间即停止消毒，未增加按键，无需其它的操作，减少使用者的操作程序。In the disinfection method of the present invention, a timing circuit is provided on the UV control panel, the ultraviolet disinfection lamp starts to work, and the time is calculated. When the set time is reached, the disinfection is stopped. No buttons are added, no other operations are required, and the user's operation procedures are reduced. .
