The front panel 12 is arranged at the opening side of the first recess 111, and the first recess 111 and the front panel 12 jointly define the cleaning cavity 50. The rear panel 13 is arranged at the opening side of the second recess 112, and the second recess 112 and the rear panel 13 jointly define the accommodation cavity 51. Specifically, the second recess 112 can be partially located above the first recess 111, and the second recess 112 and the rear panel 13 jointly define the accommodation cavity 51. Alternatively, in some other embodiments, the second recess 112 can be entirely located above the first recess 111. The isolation plate 14 is formed between the first recess 111 and the second recess 112. Specifically, the isolation plate 14 and the main shell 11 can be an integrally formed structure. The first recess 111 and the second recess 112 can be stamping formed. By designing the first recess 111 and the second recess 112 with opposite opening directions on the main shell 11, and then closing the first recess 111 and the second recess 112 by the front panel 12 and the rear panel 13 respectively, the accommodation cavity 51 and the cleaning cavity 50 can be formed in a vertical distribution manner. The structure of the shell and the manufacturing process of the shell are relatively simple and easy to manufacture.

[0033] As shown in FIG. 1, Figures 4 to 8 In some embodiments, the heat-generating body 2 is at least partially located in the second recess 112.

[0036] Specifically, in some embodiments, the toothbrush sterilizer has three working modes. The normal mode is 150 seconds of sterilization + 8 minutes of air-drying, i.e. the sterilization lamp works for 150 seconds + the fan works for 8 minutes. The strong mode is 300 seconds of sterilization + 15 minutes of air-drying and 50-degree drying, i.e. the sterilization lamp works for 300 seconds + the fan and the heating body 2 work simultaneously for 15 minutes. The plug-in super strong mode is 600 seconds of sterilization + 30 minutes of air-drying and 50-degree drying, i.e. the sterilization lamp works for 600 seconds + the fan and the heating body 2 work simultaneously for 30 minutes. In addition to displaying time information, the display screen 70 can also be used to display working mode information, which can include the above three working mode information.

[0037] In some embodiments, the sterilization unit further comprises a first substrate connected with the power supply unit, the first substrate is disposed in the accommodation cavity 51, and the sterilization lamp comprises an ultraviolet lamp disposed on the first substrate. The ultraviolet lamp emits ultraviolet light in the powered state, and the ultraviolet light sterilizes and disinfects the toothbrush head in the cleaning cavity 50. Specifically, the ultraviolet lamp can be an ultraviolet LED welded on the first substrate. The first substrate can be an aluminum substrate. The first substrate has a control module for controlling the operation of various components. The bottom of the sterilization lamp can be fixedly connected to the first substrate by welding or the like. Specifically, the first substrate has a clock module connected with the display screen 70. The clock module is an electronic component for providing time signals, timing functions and synchronous control. The specific structure and circuit principle of the clock module can refer to the prior art. The main housing 11 of the housing further has at least one adjustment button 110 connected with the first substrate for setting the parameters of the clock module to calibrate the time. As shown in Figure 5 the embodiment, there are two adjustment buttons 110 for adjusting hours and minutes respectively. The two adjustment buttons 110 are simple and easy to understand, greatly improving the user experience.

[0038] As shown in Figure 3 and Figure 4 , Figure 6 and Figure 7 in some embodiments, the toothbrush sterilizer further comprises a bracket 40 disposed in the accommodation cavity 51, and the first substrate is mounted on the bracket 40.

[0039] In some embodiments, the toothbrush sterilizer further comprises a radar chip and / or an infrared sensor connected with the first substrate. That is, the toothbrush sterilizer can comprise at least one of the radar chip and the infrared sensor. The radar chip is a kind of micro sensor based on radar frequency application. The radar chip can adopt an ultra-low power radar chip, which has a working frequency within the ISM frequency band of 5.8 GHz (i.e. 5.725 GHz ~ 5.875 GHz), and integrates circuit modules such as voltage-controlled oscillator (VCO), radio frequency transmission (TX), radio frequency reception (RX), and intermediate frequency amplifier. The VCO (voltage-controlled oscillator) output frequency point can be configured through the IIC (Inter-Integrated Circuit, integrated circuit bus) interface, and the set frequency points are dispersed within the ISM frequency band of 5.8 GHz, and the number of frequency points can reach 32. The radar chip can adopt a wide-beam radar to identify motion, and when it identifies that the user is close to the toothbrush sterilizer, it sends a corresponding instruction to the control module on the first substrate, which can trigger the display screen 70 to display real-time time information, so as to facilitate the user to know the real-time time information. The infrared sensor obtains whether the user is close to the toothbrush sterilizer based on the physical properties of infrared rays. Similarly, when the infrared sensor identifies that the user is close to the toothbrush sterilizer, it sends a corresponding instruction to the control module on the first substrate, which can trigger the display screen 70 to display real-time time information, so as to facilitate the user to know the real-time time information.

[0040] In some embodiments, as shown in FIG. 7, the display screen 70 is installed on the main shell 11. As shown in FIGS. 8 and 9, a plurality of holes 120 are formed on the front panel 12 to expose the time information displayed on the display screen 70. Figure 5 Figure 1 Figure 2

[0041] ​​​The heating body 2 comprises a second substrate connected with the power supply unit, a heating circuit arranged on the second substrate, and a temperature measuring module arranged on the second substrate. The temperature measuring module is used to realize temperature control of the heating body 2. Specifically, the heating circuit can be formed on the second substrate by etching, printing or the like. The second substrate can be an aluminum substrate. The temperature measuring module can obtain the real-time temperature of the heating body 2 and send the temperature information to the control module on the first substrate in the form of an electrical signal. In this way, when the temperature of the heating body 2 exceeds a first predetermined value, the control module cuts off the power supply and stops the heating of the heating body 2. When the temperature of the heating body 2 is lower than a second predetermined value, the control module connects the power supply and continues the heating of the heating body 2. Exemplarily, the temperature measuring module can comprise an NTC temperature sensor arranged on the second substrate. In addition to being used to display time information and working mode information, the display screen 70 can also be used to display the temperature information measured by the temperature measuring module. When the toothbrush sterilizer is in a working state, the display screen 70 can switch to display the heating temperature, so that the user can directly see the internal heating condition and ensure the effectiveness of the sterilization and drying process.

[0042] As shown in Figure 5 In some embodiments, the toothbrush sterilizer further comprises a Hall switch, which comprises a Hall sensor 81 arranged on the main shell 11 and a magnet 82 arranged on the front panel 12. The Hall sensor 81 is connected with the sterilization unit and is used to control the opening and closing of the sterilization unit according to the position of the front panel 12. Specifically, the Hall sensor 81 is connected with the sterilization unit through the first substrate. That is, the Hall sensor 81 is also connected with the first substrate as an electronic element on the first substrate. When the front panel 12 is opened, the cleaning cavity 50 (the first recess 111) is completely exposed to the air and can be directly opposite to the human body, at this time, the Hall sensor 81 and the magnet 82 are separated from each other, the Hall switch is not conductive, and the sterilization lamp of the sterilization unit is powered off and does not work, thereby avoiding the adverse effects of ultraviolet leakage on the human body; when the front panel 12 is closed, the Hall sensor 81 and the magnet 82 are close to each other and are attracted to each other, the Hall switch is conductive, and the sterilization lamp of the sterilization unit is powered on. Therefore, in the user's visual angle, if the user opens the front panel 12 during the working period of the sterilization lamp, the sterilization lamp will be turned off and the sterilization will be paused, which can effectively avoid the adverse effects of ultraviolet leakage on the human body.

[0043] It can be understood that the above embodiments only express the preferred embodiments of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application; it should be pointed out that for ordinary skilled persons in the art, the above technical features can be freely combined without departing from the concept of the present application, and a number of modifications and improvements can be made, which all belong to the protection scope of the present application; therefore, any equivalent transformation and modification within the scope of the claims of the present application shall belong to the scope of the claims of the present application.
