Referring to fig. 1, the second lid body portion 33 is first reduced in size in the second direction and then is unchanged, and the length of a section of the second lid body portion 33, the size of which is unchanged in the second direction, is not less than 20 mm. Specifically, the size of the second cover body part 33 in the second direction is reduced, and the size of the second cover body part 33 in the second direction is unchanged, so that the smooth transition is formed between one section, the waist of the second cover body part 33 in the second direction, and thus the surface of the second cover body part 33 is smooth on the premise of ensuring the flat structural characteristics of the second cover body part 33, so that the existence of sharp corners and the like in the protective cover 30 can be avoided, and the use experience of a user can be improved.

Further, since the functional module 40 is disposed on the second cover body portion 33, and the length of the section of the second cover body portion 33 with the unchanged size in the second direction is set to be not less than 20mm, it can be ensured that the functional module 40 can touch various parts in the oral cavity when the protection cover 30 is inserted into the oral cavity, so that the functional module 40 can conveniently detect or care the health status of various parts in the oral cavity.

The oral detection unit may mainly include: at least one of a camera, a pH probe, a dental plaque detection probe, a tooth cleanliness detection probe and a tooth color detection probe. Specifically, the camera can shoot the inside health status of user's oral cavity and make a video recording, can acquire the inside image in oral cavity to can convenience of customers clearly understand the oral cavity status, for example: dental plaque conditions on the teeth, inflammation in the mouth, etc., can be indicative to the user. The quantity of camera can be two or more, can make two at least cameras form two mesh discernments like this to can obtain the inside 3D image in oral cavity, can show the inside condition in oral cavity better.

Further, the pH probe can be surveyed the pH value of oral cavity mucus to can detect the pH valve of user's oral cavity environment, can assess oral cavity health status, and then maintain oral cavity health to the user and play indicative effect.

In addition, the oral cavity detecting unit can be a dental plaque detecting probe, a tooth cleanliness detecting probe or a tooth color detecting probe, and when the protective cover 30 is inserted into the oral cavity, the oral cavity detecting unit can act on teeth of a user to detect and analyze dental plaque on the teeth, the cleanliness of the teeth, the color of the teeth and the like, so that the user can know the health condition of the teeth more clearly.

So, through setting up oral cavity detecting element into camera, pH probe, dental plaque detecting probe, tooth cleanliness detecting probe, tooth colour detecting probe in at least one, can make oral cavity detecting element make a video recording the oral cavity situation through stretching into the oral cavity with safety cover 30 like this, or detect the PH value of oral cavity, dental plaque, tooth cleanliness and tooth colour to can detect the health status of at least one in tooth, gum, tongue or the oral mucosa.

The oral care unit may essentially comprise: at least one of an EMS electrode, a radio frequency electrode, and a whitening lamp.
