The LCD display screen 103, the LED indicator light 104, the button 105, the magnetic levitation motor 106, the rechargeable lithium battery 107, the micro gas sensor 110 and the Type-C charging interface 111 are all electrically connected to the PCB board 108. The electric toothbrush 100 is wirelessly connected to the cloud storage server 200. The cloud storage server 200 is used to store the oral gas detection data of the examiner. The electric toothbrush 200 stores the examiner's breath detection data through the built-in micro gas sensor 110. The smart mobile terminal device 300 is wirelessly connected to the cloud storage server 200, and the smart mobile terminal device 300 can remotely and in real time obtain the oral gas detection classification results and address information of the tester through the cloud storage server 200, remotely monitor the oral care effect, and perform early diagnosis of bad breath, warn of oral diseases, and promptly discover severe bad breath that may be caused by pathological diseases, so as to facilitate users to manage their oral health.
[0022] Furthermore, the electric toothbrush 100 also includes a limiting ring 112, a second accommodating groove 1013 is recessed at the lower end of the first accommodating groove 1012, the limiting ring 112 is embedded in the second accommodating groove 1013, the outer circumferential wall of the first accommodating groove 1012 is recessed with a plurality of limiting grooves 1014 extending along the length direction along the circumferential direction, the inner circumferential wall of the sliding cover 109 is protruding with a plurality of limiting protrusions 1091 along the circumferential direction, the limiting protrusions 1091 can be slidably embedded in the limiting grooves 1014, and the limiting protrusions 1091 can be respectively abutted against the limiting ring 112, the limiting ring plays a limiting role, and can prevent the sliding cover from slipping off the bottom of the handle cylinder.
[0023] Furthermore, the electric toothbrush 100 also includes a dust cover 113, which is covered on the lower end of the handle tube 101, and the dust cover 113 is located inside the limiting ring 112. The lower end of the handle tube 101 is recessed with a plug hole 1015, and the upper end of the dust cover 113 is protruding with a plug rod 1131.

At this time, the rotation speed of the magnetic levitation motor is low. In this way, splashing caused by excessive rotation speed of the brush head can be effectively prevented. When the brush head starts to contact the teeth and starts to clean the teeth, the pressure of the brush head gradually increases, and the rotation speed of the magnetic levitation motor increases with the increase of the pressure of the brush head, thereby effectively ensuring the teeth cleaning effect.
[0026] On the other hand, Fig. 9 As shown, the present invention also proposes an oral gas detection method based on the Internet of Things, which is performed using the above system and includes the following steps: S100: Press and hold the power button on the electric toothbrush for 3 seconds until the electric toothbrush turns on and preheats for 9 seconds, then slide the cover at the bottom of the electric toothbrush down to expose the micro gas sensor.

At the same time, the recommended social distance, breath degree, breath level, recommended social distance, specific suggestions and the tester's address information are uploaded to the cloud storage server in real time for storage, and the tester's breath degree, breath level, recommended social distance and specific suggestions are displayed through the APP on the smart mobile terminal device and the LCD display on the electric toothbrush respectively; S500: After the test is completed, press and hold the power button on the electric toothbrush for 3 seconds to turn it off, and slide the sliding cover at the bottom of the electric toothbrush upwards to cover the micro gas sensor.
[0027] Furthermore, in step S400, the electric toothbrush collects the exhaled gas from the tester's mouth through a micro gas sensor, and analyzes it through a built-in algorithm to obtain the tester's breath degree, and determines the breath level according to the tester's breath degree. At the same time, according to different breath levels and breath degrees, a recommended social distance and specific suggestions are given, and the corresponding color is displayed by the LED indicator on the electric toothbrush. The breath level is divided into 4 levels: Level 1 to Level 4, specifically: The LED indicator light is green, indicating that the breath level is Level 1, the breath level is mild, and the specific advice is: no need to worry; The LED indicator is yellow, indicating that the breath level is Level 2 and the breath level is moderate.

Bad breath may be related to pathological diseases, such as digestive system diseases, respiratory system diseases, diabetes, liver disease, etc. It is recommended to go to a regular hospital for systematic examination and treatment.
[0028] Specifically, the micro gas sensor uses an ultra-precision MEMS sensor with a detection accuracy of up to one ten-millionth (0.1ppm). It can quickly sense breath conditions by exhaling for 5 seconds, and is more hygienic if not ingested.
[0029] Specifically, the technical solution of the present invention can accurately measure the main volatile sulfides of bad breath gas through the micro gas sensor at the bottom of the electric toothbrush, scientifically and effectively perform breath perception and bad breath control monitoring, and determine the breath level into 4 levels according to the degree of bad breath: Level 1 to Level 4. By determining the severity of the bad breath, a reasonable social distance is recommended to avoid social embarrassment. By detecting the gas exhaled from the user's mouth, it helps the user to improve his or her breath cognition, so that the degree of bad breath can be understood by himself or herself, and breath anxiety is alleviated. The effect of oral care is monitored, and bad breath is diagnosed early, oral diseases are warned, and severe bad breath that may be caused by pathology is discovered in time. Breath perception and bad breath control monitoring are performed scientifically and effectively. The address information of the tester can also be recorded at any time to provide corresponding life services.
