Description

Detachable headrest and dental chair Technical Field The application relates to the technical field of dental chair headrests, in particular to a detachable headrest and a dental chair. Background The shape of current dental chair headrest is fixed, makes things convenient for the patient to lie down, but to the patient of fixing hair through hairband, chignon etc. the hair is directly pressed on the headrest, can lead to the head position unfixed, and then leads to the oral cavity to open the unable fixed of position, influences subsequent oral examination or treatment. Longer hairs are scattered and placed, the hairs possibly float into the oral cavity during operation to further influence oral examination or treatment, and the hairs possibly adhere to saliva, clear water or the like during the oral examination or treatment, so that experience feeling of a patient is reduced. In addition, the headrest is easily stained with saliva, stains, germs, etc. during oral examination or treatment, and the experience of the next patient is reduced. Therefore, the conventional headrest for a dental chair is not suitable for a customer with long hair or hair bands or chignons, and the headrest is easily contaminated with stains and germs. Disclosure of utility model In view of the above-mentioned shortcomings of the prior art, the present application aims to provide a detachable headrest and a dental chair, which aims to solve the problems that the existing dental chair headrest is not suitable for customers with long hair or hair belts or chignons, and the headrest is easy to be stained with stains and germs.
