The spectral sensor 7 and the light source 8 are provided at the front end of the nozzle 6 for spectral detection of the tooth surface.

[0046] The specific structure of the above-mentioned rotatable spray hole can be various. Optionally, the rotatable spray hole is a paddle with an inclined nozzle arranged at the water outlet of the spray hole, which can be pushed by the water flow and spray water while rotating, thereby dispersing the water flow pressure and reducing the probability of bleeding inside the oral cavity.

[0047] The light source may be an LED light source capable of emitting light of a preset wavelength. The wavelength range emitted by the light source is preferably 230-5000nm. For example, it may be 230nm, 300nm, 350nm, 400nm, 500nm, 600nm, 700nm, 800nm, 900nm, 1000nm, 1500nm, 2000nm, 2500nm, 3000nm, 3500nm, 4000nm, 4500nm, 5000nm, etc., which will not be described one by one here.

[0049] Specifically, the type of pump is an electric pump or a pneumatic pump. When there is a regulating valve inside the pump, the regulating valve is set at the water outlet or water inlet. If a transformer is used to regulate the water flow, the transformer needs to be set in front of the power supply receiving end of the electric pump, or in front of the air supply receiving end of the pneumatic pump.

[0050] In the embodiment of the present invention, the light source projection (detection) angle range is 0°-40°, the LED light source diameter is 0.5 mm to 0.9 mm, and the sensor diameter is 1 mm to 2 mm.

[0051] The spectral sensor 7 is a sensor that can measure the reflection and / or scattering spectrum of the surface of an object, and can be used to identify the color, material, composition and other characteristics of the surface of the object. The spectral sensor 7 includes a quantum dot filter and a detector. The quantum dot filter is located on the receiving side of the detector, and the quantum dot filter is used for filtering light in different bands.

[0052] The spectrum sensor 7 is not limited to the above-mentioned quantum dot spectrum sensor, and may also be any one of a micro-engraved grating spectrum sensor and a Fabry-Perot cavity interferometer filter sensor.

Specifically, the waterproof layer can be a film attached to the front side of the spectrum sensor receiving end.

[0054] The controller 4 is used to control the working state of the pumping device 2 and the flushing head 3. The spectral sensor 7 receives the spectral signal reflected and / or scattered by the light source 8 after being irradiated to the tooth, and converts the spectral signal into an electrical signal and sends it to the controller 4. The controller 4 pre-stores the corresponding relationship between the electrical signal and the tooth state, and the corresponding relationship between the tooth state information and the operating parameters. The controller 4 obtains the corresponding operating parameters according to the received electrical signal, and controls the pumping device 2 according to the operating parameters to adjust the intensity of the water flow sprayed by the nozzle 6, or controls the pumping device 2 according to the operating parameters to adjust the frequency of the water flow sprayed by the nozzle 6, or controls the pumping device 2 according to the operating parameters to adjust the intensity and frequency of the water flow sprayed by the nozzle 6. The controller can also transmit the obtained operating parameters and / or tooth state information to the communication module 9, and the communication module 9 sends the operating parameters to the cloud or wireless terminal. The wireless terminal can be a user's mobile phone or other electronic device.

[0055] The tooth status includes: tooth surface features and / or gum status, which may include: tooth surface pigmentation, dental plaque, enamel damage, caries, gum position and other health conditions.

[0056] The communication module 9 is a Bluetooth module or a Wi-Fi module, which is used to exchange data with the cloud or a wireless terminal.

[0057] The controller 4 includes a single chip microcomputer or a microprocessor. The electric tooth washer also includes a display connected to the controller signal, and the display is used to display tooth status information and / or operating parameters.

[0058] Example 2

[0059] like Figure 4 As shown, the embodiment of the present invention also provides a control method of an electric tooth washer, the method comprising:

[0060] Step S1: receiving the reflected spectrum signal and / or scattered spectrum signal after the light source irradiates the tooth, and converting it into an electrical signal and sending it to the controller 4.

[0061] Step S2: The controller 4 obtains tooth state information corresponding to the received electrical signal based on the received electrical signal and the correspondence between the electrical signal and the tooth state stored in advance, and obtains corresponding operating parameters based on the obtained tooth state information and the correspondence between the tooth state information stored in advance and the operating parameters, and controls the pumping device 2 according to the operating parameters to adjust the intensity and / or frequency of the water flow sprayed by the nozzle 6, wherein the tooth state includes: tooth surface characteristics and / or gum state.

[0062] The correspondence between the tooth status information and the electrical signal is obtained by processing and analyzing the electrical signal received from the spectral sensor to obtain the tooth spectral data, using a preset algorithm or model, marking a large amount of tooth spectral data and corresponding tooth surface features and / or gum status and other properties, training with graph neural network technology (GraphNeuralNetworks), and structurally matching the spectral data information and the above properties. Similarly, the operating parameters are also trained through the model to obtain the correspondence between the tooth status information and the operating parameters. The above-mentioned tooth surface features include the chromaticity, dental plaque, pigmentation, enamel damage, caries, etc. of the tooth surface, and the gum status includes the gum position, etc.

[0063] The operating parameters also include the wavelength emitted by the light source, and the controller 4 controls the wavelength range emitted by the light source according to the operating parameters. Optionally, the operating parameters also include: operating time, and the controller 4 can control the electric toothbrush to shut down according to the operating time.

[0064] like Figure 3As shown, in a specific embodiment provided by the present invention, when the user needs to use an electric tooth washer for oral cleaning, step S301 is first executed to fill the water tank with water and put the rinse head into the mouth, step S302 is executed to press the switch button to start the pumping device and the rinse head; step S303 is executed: the pumping device pumps water out of the water tank and transports it to the rinse head through a pipeline, steps S304 and S305 are executed, and the nozzle of the rinse head sprays water onto the tooth surface with a certain intensity and frequency for cleaning; at the same time, the light source of the rinse head projects light onto the teeth, step S306 is executed, the spectral sensor receives the reflection spectrum and / or scattering spectrum of the tooth surface, step S307, the spectral sensor sends the detection result to the controller, the controller adjusts the working state of the pumping device and the rinse head according to the detection result, and the controller sends the monitoring data to the cloud or mobile phone through the wireless communication module, the cloud or mobile phone records, analyzes and monitors the detection data, and AI proposes targeted solutions. Of course, when using the electric tooth washer, the nozzle of the rinsing head may not spray water onto the tooth surface first, that is, S304 may not be executed first, and the spectrum sensor may be used for detection first, and the pumping device may be controlled according to the detection result, thereby controlling the spray intensity and / or frequency of the nozzle. The present invention does not specifically limit the execution order of the above steps.

[0065] The electric tooth washer proposed in the embodiment of the present invention can send oral hygiene data to the cloud or a mobile phone or other device for storage, processing, monitoring and other operations, and provide corresponding suggestions or warnings based on the data analysis results.

[0066] The electric tooth washer provided by the present invention can record and analyze long-term oral hygiene data through cloud or mobile phone devices, evaluate cleaning effects or improvement plans, and interact with users through cloud or mobile phone devices to provide corresponding suggestions or warnings, thereby enhancing users' oral health awareness and habits.

[0067] The electric tooth washer provided by the present invention can be trained with a graph neural network model through a large amount of pre-stored tooth spectral data and corresponding tooth surface features and gum position information, so that the spectral data information and the corresponding tooth surface features and gum status information are structurally matched. The model can be trained based on the above information to establish a corresponding relationship between the spectral data (electrical signal) and the tooth state, and a corresponding relationship between the tooth state information and the operating parameters. The controller obtains the tooth state information based on the received electrical signal (spectral data), and then obtains the corresponding operating parameters based on the obtained tooth state information and the pre-stored corresponding relationship between the tooth state information and the operating parameters, and controls the pumping device based on the operating parameters to adjust the intensity and / or frequency of the water flow sprayed from the nozzle. For example: for parts with dental plaque or caries (the spectral curve will be different in the visible light band and the shallow ultraviolet band (150nm-700nm)), the controller controls to increase the water flow intensity and use ultraviolet light to kill bacteria or prevent the development of caries. At the same time, the location of caries is sent to the user's mobile phone to remind the user to seek medical treatment as soon as possible; for parts without dental plaque or caries, use ordinary water flow intensity to clean the teeth, and use infrared light to promote blood circulation or enhance tooth enamel; for parts with more tartar, increase the water flow intensity and remind the user of the tartar problem, and remind the user to seek medical treatment as soon as possible through the user's mobile phone; for gums (the spectral curve will be different in the visible light band (400nm-700nm)), automatically reduce the water flow intensity to protect the gums, reduce bleeding, and promote healing.

[0068] The dental status is monitored over a long period of time through the cloud or mobile phone. When the dental status is updated, cleaning suggestions are given to the user. The cleaning suggestions include changing the cleaning water, adjusting the cleaning time, using auxiliary products, and seeking medical treatment as soon as possible.

[0069] The control method of the electric tooth washer provided by the present invention can improve the cleaning effect and make the cleaning experience more comfortable by identifying the health status of the tooth surface and adjusting the flushing mode according to the health status; by identifying the gums, the water flow intensity is reduced or the water flushing is stopped when encountering the gums, so as to protect the gums, reduce gum bleeding, and make the cleaning experience more comfortable; by transmitting the detection data to the cloud or mobile phone, recording, analyzing and monitoring the long-term tooth cleaning situation on the cloud or mobile phone, AI proposes targeted solutions, thereby improving the cleaning effect and health management level; by using a wireless communication module, data exchange with the cloud or mobile phone can be realized, thereby improving the convenience and intelligence of cleaning.

[0070] The beneficial effects that can be achieved are:

[0071] 1) A spectral sensor and light source are provided at the front end of the rinsing head, which can perform spectral detection on the tooth surface and identify the health conditions such as pigmentation, dental plaque, enamel damage, caries, and gum position on the tooth surface;

[0072] 2) The controller intelligently controls the pumping device according to the spectral signal recognition result, and adjusts the intensity and / or frequency of the water flow, so that the electric tooth washer can use different flushing intensities according to the different chromaticity and health conditions of the tooth surface;

[0073] 3) The device is equipped with a wireless communication module inside, which can wirelessly transmit the recognition results and related data obtained by the controller to the cloud or mobile phone, record, analyze and monitor the long-term teeth cleaning status on the mobile phone, and AI will provide targeted solutions.

[0074] The above specific embodiments have been described in detail for the present invention, but it is obvious to those skilled in the art that some modifications or improvements can be made on the basis of the present invention. Therefore, these modifications or improvements made on the basis of not departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
