Description

FIELD OF THE INVENTION

The invention relates to a tool for oral cleaning, and particularly relates to a visual oral scraping spoon for cleaning teeth, interdental spaces and oral cavities.

BACKGROUND OF THE INVENTION

When the teeth are not cleaned thoroughly for a long time or when people smoke, drink tea or drink alcohol for a long time, it is very easy to cause dental problems such as dental calculus, dental plaque and pigmentation on the surface of the teeth, and it is easy to cause thickening of the coated tongue. At present, the dental calculus, dental plaque, pigmentation, coated tongue and the like are usually cleaned in a professional stomatological hospital.

At present, in a tooth washing process in a hospital or a dental clinic, the common way to clean the dental calculus, dental plaque and pigmentation is to extend a work head of a tooth cleaner in high-speed rotation or vibration into the oral cavity so as to loosen the dental plaque and break the dirt on the surface of the teeth under the friction or vibration action of the work head, thereby achieving the purpose of cleaning the dental calculus, dental plaque and pigmentation.

Because the work head needs to be extended into the oral cavity and the light in the oral cavity is very dark, it is very difficult to see the condition in the oral cavity. Therefore, in the prior art, generally, the dental calculus, dental plaque, pigmentation, coated tongue and the like in the oral cavity of a patient can only be cleaned by a dentist by virtue of professional instruments and a dental treatment table or a dental treatment chair in a dental clinic.

At home, it is difficult for a patient to use the oral cleaning instruments in the prior art to clean the dental calculus, dental plaque, pigmentation and the like in the oral cavity. At present, when a coated tongue cleaner, various toothbrushes or a flusher is used to clean the teeth, dorsum and the like, because the light in the oral cavity is dark or a part to be cleaned is relatively hidden and difficult to observe, the patient can only perform these cleaning operations by feeling. Generally, the part to be cleaned cannot be cleaned, but the parts that do not need to be cleaned are cleaned repeatedly, causing excessive damage to the teeth or soft tissues in the oral cavity. Particularly, when the patient uses a tool in high-speed rotation or vibration, such as a high-speed grinding head, an ultrasonic grinding head or a dental bur, to clean the oral cavity, once the work head deviates from the work part, it is very easy to cause accidental injury.

In order to overcome the defects of the prior art, it is necessary to develop a tool which can be used by the patient at home to carry out targeted cleaning the teeth or coated tongue by using a display screen of a mobile phone in a visual state.
