Description

Technical Field

[0001] The utility model relates to the technical field of dental instruments and equipment, in particular to a spittoon. Background Art

[0002] Oral health is an important part of overall health. Various oral diseases not only reduce people's quality of life, but are also closely related to various systemic diseases throughout the body. With the improvement of people's living standards and oral health awareness, the frequency of people receiving oral treatment has gradually increased. Dental chairs are essential medical equipment in oral treatment, which are used by dentists to diagnose and treat patients and provide a comfortable medical environment for oral patients.

[0003] During oral treatment, the operation of dental chair instruments such as the dental drill will increase the amount of liquid in the patient's mouth. In addition, the patient's own local bleeding requires the patient to constantly rinse his mouth to remove the residues, debris, and blood in the mouth. In a dental chair, a spittoon is an indispensable part. After rinsing the mouth, the patient spits out the mouthwash in the mouth through the spittoon. The water in the existing spittoon tray flows into the three-way pipe below through the sink and the sewage pipe, and is discharged from the drainage pipe at the other end of the three-way pipe. The remaining end of the sewage pipe is connected to the ventilation pipe. The upper side of the sink is sealed with a cover plate and glue, which is prone to water leakage. The connection between the sewage pipe and the sink is also prone to water leakage, the ventilation effect is poor, and the drainage is slow. Utility Model Content
