[0041] like Figures 1 to 4 As shown, this utility model discloses an electric toothbrush with oral monitoring, including a handle 100 and a brush head 200. The handle 100 includes a handle housing 110, a power module 120, a drive module 130, a camera module 140, and an air blowing module 150. The brush head 200 includes a bristle section 210, a connecting shaft 220, and a brush head housing 230. The power module 120 includes a power supply component 121, a main board 122, and a button 123. The main board 122 is fixed inside the handle housing 110. The power supply component 121 and the button 123 are both electrically connected to the main board 122. The handle housing 110 has an operation window 111 through which the button 123 is exposed, allowing the user to operate the button 123. The power supply component 121 is a battery compatible with the handle housing 110. The camera module 140 includes a camera housing 141, a camera 142, a camera lens 143, and a camera circuit 144. The camera housing 141 is connected to the handle housing 110. The camera housing 141 has a camera window, and the camera lens 143 covers the camera window to prevent liquid from entering through the camera window. The camera 142 is fixed inside the camera housing 141 and faces the camera lens 143. The camera lens 143 protects the camera 142 from damage. The purpose of the camera 142 is to allow real-time monitoring of brushing or examination of oral health during brushing. The camera circuit 144 provides an electrical signal connection between the camera 142 and the mainboard 122. The mainboard 122 is powered by a power supply 121 and can issue commands to the camera 142 to capture or monitor the oral cavity.

[0042] During brushing, the system monitors oral health. The mouth contains not only saliva but also a large amount of toothpaste foam. To prevent the camera 142 from being obstructed by oral fluids during recording and to avoid toothpaste foam adhering to the camera lens and severely affecting the recording effect, an airway 1411 is provided on the camera housing 141. One end of the airway 1411 is located on one end of the outer side of the camera lens 143. The air blowing module 150 includes an air pump 151 and a flexible air tube 152. 52 is connected between the end of the airway 1411 away from the camera lens 143 and the air pump 151. The air pump 151 is electrically connected to the main board 122. Before the camera 142 needs to take a picture, the main board 122 can issue a blowing command to the air pump 151. The airflow produced by the air pump 151 passes through the flexible air tube 152 and the airway 1411 in sequence and blows air onto the camera lens to blow away the residue on the camera lens before taking a picture, thereby achieving a clear monitoring effect inside the oral cavity so as to have a clearer oral health report.

[0043] To further improve the monitoring effect of the oral cavity monitoring electric toothbrush, the camera module 140 also includes an illumination lamp, which is also fixed inside the camera housing 141 and faces the camera lens 143. It can provide supplementary lighting for the shooting and monitoring of the camera 142, resulting in better shooting effect.

[0044] The drive module 130 includes a drive motor 131 and a drive shaft 132. The drive motor 131 is fixed inside the handle housing 110 and is electrically connected to the main board 122. The drive motor 131 controls the rotation of the drive shaft 132, which protrudes from the head of the handle housing 110. The connecting shaft 220 is inserted into the drive shaft 132, which drives the brush bristle part 210, which is fixedly connected to the connecting shaft 220, to rotate synchronously, thus cleaning the teeth. Specifically, the connecting shaft 220 is movably engaged with the brush head housing 230, which is connected to the camera housing 141. The rotation and cleaning of the connecting shaft 220 and the brush bristle part 210 will not cause vibration in the brush head housing 230. The brush head housing 230 and the camera housing 141 together form a stable structure, which helps the camera 142 to capture images smoothly.

[0045] Specifically, the brush handle 100 also includes a fixing bracket 160, which is snapped into the inside of the handle housing 110. The drive motor 131, the power supply unit 121 and the air pump 151 are sequentially fixed to the fixing bracket 160 to stabilize and protect the assembly structure of the three components.

[0046] In this embodiment, a hydrophobic protective layer is provided on the outer surface of the camera lens 143. The camera lens 143 forms a hydrophobic protective layer through a nano-coating process, which makes it difficult for water to adhere to the surface. When air is blown, the substances on the camera lens 143 can be blown away quickly and no water marks will remain on the surface.

[0047] For example, the end of the airway 1411 near the camera lens 143 is configured as a flat opening, the length of the flat opening is parallel to the camera lens 143, and the shape of the flat opening fits the width of the camera lens 143, which can improve the efficiency of air blowing cleaning.

[0048] Understandably, the airway 1411 has a backflow preventer at the end near the camera lens 143 to prevent liquid from entering the airway 1411. The backflow preventer can only open when airflow is out, and cannot allow gas or liquid to enter the airway 1411 in the reverse direction, thus preventing water from entering and damaging the oral monitoring electric toothbrush.

[0049] Furthermore, the power module 120 also includes a display screen 124. A display window 112 is provided on the handle housing 110, through which the display screen 124 protrudes from the handle housing 110. The display screen 124 is electrically connected to the motherboard 122 and the camera 142, respectively. It can receive signals from the camera 142, display its captured content, and generate specific oral health reports. The display screen 124 can also be used to display parameters such as cleaning time, intensity, and battery level of the oral monitoring electric toothbrush. In another embodiment, the display screen 124 can be connected to the motherboard 122 and the camera 142 via Bluetooth. The display screen 124 can be flexibly held by the user in the other hand (not the handle 100), allowing them to view the oral health status of corresponding areas while brushing their teeth, thus improving the flexibility of use.

[0050] Specifically, the camera window is set at a first preset distance from the bristle part 210, and the display screen 124 is set at a second preset distance from the bristle part 210. The first preset distance is less than the second preset distance, meaning that the camera 142 is closer to the bristle part 210 when it is not obstructed by the structure, and can go deeper into the corresponding monitoring position in the oral cavity. The display screen 124 needs to be relatively far away from the bristle part 210 and the camera 142 that enter the oral cavity, so as to avoid problems such as liquid intrusion damaging the display screen 124 or toothpaste foam adhering to the display screen 124 causing it to be unclear.

[0051] In this embodiment, the brush head 200 is a replaceable part, and the bristle part 210 is a consumable. The connecting shaft 220 is selectively engaged with the drive shaft 132, and the brush head housing 230 is selectively engaged with the camera housing 141. This allows users to easily replace the bristle part 210 that has been used for a long time, ensuring oral health, while extending the overall service life of the oral monitoring electric toothbrush and reducing the cost of use.

[0052] For example, a flexible rubber part 101, specifically a rubber ring, is interference-fitted between the camera housing 141 and the handle housing 110 to ensure stable assembly and detachability between them. A flexible rubber part 101, specifically a waterproof soft rubber sleeve, should also be interference-fitted between the camera housing 141 and the drive shaft 132. Besides its assembly and connection function, this also enables waterproofing of the oral monitoring electric toothbrush, improving its safety during use.

[0053] Optionally, the flexible air tube 152 is coiled inside the handle housing 110 to protect its safety. To prevent the flexible air tube 152 from becoming tangled inside the handle housing 110, a cable tie 113 is provided. The cable tie 113 guides and positions the flexible air tube 152, improving the assembly stability of the blowing module 150. Figure 4 As shown, the cable harness 113 is provided with a cable harness groove 1131 and a cable harness hole 1132. The flexible air tube 152 extends along the cable harness groove 1131 and passes through the cable harness hole 1132 to restrict the free movement of the flexible air tube 152.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
