[0047] The utility model provides a kind of oral irrigator, such as Figure 1 As shown, oral irrigator includes: camera module, main control chip assembly and WIFI antenna. Among them, camera module, WIFI antenna are connected with main control chip assembly. Camera module is used to send the oral cavity state information photographed to main control chip assembly, and main control chip assembly sends oral cavity state information to mobile terminal in wireless transmission mode by WIFI antenna.

[0048] Specifically, after oral irrigator is woken up, camera module starts to photograph oral cavity internal picture or video, then transmits the picture or video data photographed to main control chip assembly. After data processing, main control chip assembly sends oral cavity state information to mobile terminal in wireless transmission mode by WIFI antenna. Among them, mobile terminal can be mobile terminal device such as mobile phone, tablet computer.

[0049] The utility model provides a kind of oral irrigator, by adopting wireless transmission mode and send oral cavity state information to mobile terminal, eliminate the USB line between camera module and host computer equipment, avoid the interference of USB line, improve the convenience of user use. At the same time, by adopting wireless transmission mode, avoid the problem of cost increase caused by using computer or professional equipment to read USB camera information.

[0050] In an alternative embodiment, the main control chip assembly is integrated with wireless communication function.

[0051] Specifically, main control chip assembly can adopt CPU main control chip integrated with wireless communication function. When main control chip assembly is integrated with wireless communication function, CPU main control chip transmits to the App of mobile phone or other mobile terminal by the wireless communication mode integrated by itself after data processing, so that oral irrigator has the function of photographing tooth or oral cavity internal condition. In addition, on the basis of obtaining tooth or oral cavity internal condition, App can be matched with image recognition software algorithm, so as to achieve the purpose of automatically identifying tooth, oral cavity internal cleaning and health condition, and App can generate health report and give treatment scheme.

[0053] Specifically, the master control chip can adopt a general CPU master control chip without integrated wireless communication, and then an independent wireless communication module is externally connected. At this time, the working mode of the master control chip assembly is that the camera transmits the photographed picture or video information to the CPU master control chip first, then the CPU master control chip forwards the data to the externally connected wireless communication module after processing the data, and then the wireless communication module sends the oral cavity state information to the mobile terminal in a wireless transmission mode through the WIFI antenna, so as to identify the health condition of the teeth in combination with the image recognition algorithm.

[0054] In an alternative embodiment, as shown in Figure 2 The oral irrigator further comprises a battery assembly and a sensor assembly. The battery assembly and the sensor assembly are both connected with the master control chip assembly. The battery assembly is used to provide power support for the work of all components of the oral irrigator. The sensor assembly calculates the acceleration of the oral irrigator according to the deformation of the spring inside it, and calculates the tilt angle of the oral irrigator according to the position change of the mass inside it. The sensor assembly sends the acceleration and the tilt angle to the master control chip assembly. The master control chip assembly judges whether the oral irrigator is picked up according to the acceleration and the tilt angle. When it is determined that the oral irrigator is picked up, the oral irrigator is woken up.

[0055] Specifically, the working principle of the battery assembly of the oral irrigator mainly includes charging and discharging. The charging part of the oral irrigator usually adopts a Micro-USB charging interface, which cooperates with a lithium battery charging and discharging management chip to manage the charging. During the charging process, the charging management chip converts alternating current into direct current through a rectifier circuit, and charges the battery through a charging control circuit. When the battery is fully charged, the charging control circuit automatically cuts off the charging current to prevent overcharging. The discharging part of the oral irrigator mainly refers to the battery providing power for the oral irrigator to drive the motor to work.

[0056] The sensor assembly mainly adopts a gravity sensor. Specifically, the sensor assembly is usually composed of a micro-electro-mechanical system, which contains a mass and a spring structure. When the oral irrigator moves, the mass moves due to inertia, and the spring deformation changes the capacitance or resistance. The sensor converts these changes into electrical signals to detect the acceleration and direction of the device. When the oral irrigator is tilted, the mass moves due to gravity, and the sensor determines the tilt angle by measuring the position change of the mass. The electrical signals output by the sensor are amplified and filtered, and then analyzed by the master control chip assembly to calculate the motion state and tilt angle of the oral irrigator. After the master control chip assembly obtains the data of the sensor assembly, it determines whether the oral irrigator is picked up. When it is determined that the oral irrigator is picked up, the oral irrigator is woken up from the low-power sleep state to enter the normal working state. The sensor assembly can adopt the circuit structure as shown in Figure 3 .

[0057] In an alternative embodiment, as shown inFigure 2 As shown in the figure, the oral irrigator further comprises a water pump and a driving assembly.

The LED indicator is used to indicate the normal operation, low power and charging state of the oral irrigator. The LCD display screen is mainly used to display the working mode and battery power of the oral irrigator, and can also be used to display the charging state and low power. The storage assembly is used to store the picture information content required to be displayed by the LCD. The storage assembly can be integrated in the CPU, that is, a CPU with a large internal FLASH capacity can also be used to store the picture information required to be displayed, so that there is no need to externally mount the storage assembly.
