Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
In order to pay attention to the cleaning method and improve the oral cleaning effect of the user when the user uses the cleaning device to clean the oral cavity, an embodiment of the present utility model proposes an oral cleaning device, and referring specifically to fig. 1, fig. 1 is a block diagram of the oral cleaning device according to the embodiment of the present utility model, where the oral cleaning device includes a handle 110, a sensor module 120, a main control module 130 and a power module 140; the sensor module 120 is fixed on the handle 110, and the sensor module 120 is further connected with the main control module 130, and the power module 140 is connected with the sensor module 120 and the main control module 130 respectively.
The handle 110 is used to adjust the relative position between the sensor module 120 and the interior of the user's mouth. When the user uses the oral cleaning device, the user can manually contact the handle 110 and control the orientation of the oral cleaning device by adjusting the position of the handle 100. Since the sensor module 120 is fixed to the handle 110, the sensor module 120 rotates when the handle 110 rotates, and the relative position between the sensor module 120 and the user's mouth also changes. For example, when a user uses an electric toothbrush to clean teeth, the user adjusts the cleaning direction by turning the handle.
The sensor module 120 is configured to obtain an induction signal generated during the adjustment of the handle 110, and send the induction signal to the main control module 130, where the magnitude of the induction signal changes with the change of the relative position. The sensor module 120 is used for sensing a human body, and can acquire sensing signals with different intensities according to the distance between the sensor module 120 and the human body, and it can be understood that the sensing signals acquired when the sensor module 120 is far away from the human body are weaker, and the sensing signals acquired when the sensor module 120 is near to the human body are stronger. When the user rotates the handle 110 while using the oral cleaning device, the distance between the sensor module 120 and the oral cavity of the human body will change along with the change of the handle 110, and the magnitude of the sensing signal will also change along with the change of the distance between the sensor module 120 and the oral cavity of the human body.
The main control module 130 is configured to receive the sensing signal, and output a use prompt, where the use prompt is configured to prompt a user to correct a use mode. After receiving the sensing signal sent by the sensor module 120, the main control module 130 records the magnitude of the sensing signal, and determines whether the user's method is correct or whether the cleaning mode is correct according to the magnitude of the sensing signal and the change of the sensing signal. When the cleaning method of the user is wrong, the main control module 130 can send out a use prompt, and guide the user to clean the oral cavity by using the correct cleaning method by sending out a correct use prompt, so as to achieve the purpose of improving the oral cavity cleaning effect of the user.
The power module 140 is used to provide a voltage to the oral cleaning device. The power module 140 may be a linear regulated power supply that provides a regulated voltage to the subsequent components.
In the embodiment of the utility model, the sensor module 120 is utilized to acquire the sensing signal generated in the adjustment process of the handle 110 and output the sensing signal to the main control module 130, so that the main control module 130 can output a use prompt to remind a user to correct the use mode, so that the user can notice the cleaning method and improve the cleaning effect.
In one possible embodiment of the utility model, the sensor module 120 includes: a preset number of sensor groups, each sensor group comprising two sensors, and the two sensors of each sensor group being symmetrical based on the central axis of the handle 110; each sensor in the sensor group is respectively used for acquiring the induction signals generated in the adjustment process of the handle 110 and sending the induction signals to the main control module 130.
In particular, two sensors in each sensor group are symmetrically placed, and the received sensing signal of each sensor is different. For example, a group of sensor groups is provided, the sensor 1 and the sensor 2 are symmetrically arranged, the sensor 1 is arranged at the front position of the handle 110, and the sensor 2 is arranged at the back position of the handle 120.
When cleaning the outside of the oral cavity, the sensor 1 is opposite to the oral cavity and is closest to the oral cavity, and the signal quantity of the sensing signal received by the sensor 1 is strongest; the sensor 2 faces away from the oral cavity and is furthest away from the oral cavity, and the sensing signal received by the sensor 2 is the weakest in signal quantity. When cleaning the inner side of the oral cavity, the sensor 2 is opposite to the oral cavity and is closest to the oral cavity, and the signal quantity of the induction signal received by the sensor 2 is strongest; the sensor 1 faces away from the oral cavity and is furthest away from the oral cavity, and the sensing signal received by the sensor 1 is the weakest in signal quantity.
Therefore, the position information of the oral cavity cleaning device relative to the human body can be judged according to the magnitude of the received sensing signal of each sensor, and the cleaning method of the user can be judged according to the change of the sensing signal.
In order to prevent interference of water trace and foam to the sensor during operation, the sensor in the sensor group is a pyroelectric infrared sensor in the embodiment of the utility model. The pyroelectric infrared sensor has the advantages that when the oral cavity cleaning device works, the device is not afraid of water and shielding of foam, can be more suitable for the actual use environment of the oral cavity cleaning device, and brings better use effect.
In order to enhance the sensitivity of the pyroelectric infrared sensor to receive the sensing signal, the oral cleaning device further comprises a fresnel lens mounted outside the pyroelectric infrared sensor. The Fresnel lens is used for enhancing the sensitivity of the pyroelectric infrared sensor when the pyroelectric infrared sensor acquires the sensing signal.
Specifically, referring to fig. 2, fig. 2 is a schematic structural diagram of an oral cavity cleaning device according to an embodiment of the present utility model, a pyroelectric infrared sensor is mounted inside a handle head of the oral cavity cleaning device, and a fresnel lens is mounted outside the oral cavity cleaning device, wherein the pyroelectric infrared sensor can exert the maximum effect only by being matched with the fresnel lens, and the fresnel lens divides infrared light into a visible region and a blind region, and simultaneously has a focusing effect, so that the sensitivity of the pyroelectric human body infrared sensor is greatly increased. For example, without the fresnel lens, the pyroelectric infrared sensor may have a detection radius of less than 2 meters, and may be as large as 10 meters or more with the fresnel lens.
Further, the sensor group is fixed to the head of the handle 110, and the head of the handle 110 is made of infrared transmitting material. According to the embodiment of the utility model, through the shape selection and special treatment of the material of the handle 120, namely the material at the position of the sensor is selected to be infrared-transmitting, or the whole handle is infrared-transmitting, the beautifying spraying can be performed locally for the aesthetic property, and when the sensor area needs to be reserved and not covered by the infrared-resistant material, the sensing effect of the pyroelectric infrared sensor is better. When the structure is used, the handle of the oral cavity cleaning device does not need holes, so that water can be prevented from entering the oral cavity cleaning device, and the stability and reliability of the oral cavity cleaning device in use are improved.
In order to obtain a better monitoring effect, the oral cavity cleaning device further comprises a lens module, wherein the lens module is fixed on the head of the handle 110 and is respectively connected with the main control module 130 and the power supply module 140; the lens module is used for sending the shot image data to the main control module 130. The lens module comprises two lenses, and the two lenses of the lens module are symmetrical based on the central axis of the handle 110; each lens of the lens module is used for transmitting the photographed image data to the main control module 130.
Specifically, the main control module 130 can process the image data and the sensing signal after receiving the image data and the sensing signal, and determine the position information of the oral cavity cleaning device relative to the human body, and the cleaning method of the user, and the determination result is more accurate by adding the lens module.
