Description

Technical Field

[0001] The present invention relates to the technical field of dental treatment, and in particular to a dental treatment chair. Background Art

[0002] Dental chairs are used for oral surgery and examination and treatment of oral diseases. Most dental chairs are electric. The whole machine is fixed to the ground with a base plate, and the base plate is connected to the upper part of the dental chair through a bracket. The movement of the dental chair is controlled by the control switch on the back of the chair. Its working principle is: the control switch starts the motor to run and drive the transmission mechanism to move the corresponding parts of the dental chair. According to the needs of treatment, the control switch button is operated, and the dental chair can complete the actions of rising, falling, tilting, supine position and resetting. The comprehensive dental treatment chair is an essential medical equipment for dentists, providing a comfortable medical environment for oral patients. Dentists further guarantee the treatment effect of oral patients through intelligent and diversified medical instruments.

[0003] After searching, the patent publication number CN218889895U discloses a patent named "An Adjustable Patient Treatment Chair for Dentistry". The technical problem to be solved is that many dental chairs cannot adjust the angle of the head position according to the doctor's needs, and there is no way to adjust the height of the display screen according to the patient's needs, resulting in the patient being unable to see the health status of his or her teeth in time. By setting a threaded rod, rotating the nut drives the threaded rod to rotate. Since the slider is engaged with the threaded rod, when the threaded rod rotates, it will drive the slider to slide left and right in the internal slide groove of the seat. At this time, the rack fixedly connected to the slider will slide left and right accordingly. Since the gear is engaged with the rack, and the length of the rack is one-fourth of the circumference of the gear, when the rack slides, it will drive the gear to rotate up to 90°. At this time, the rotating column fixedly connected to the gear will rotate up to 90°. Since the cushion is fixedly connected to the rotating column, when the rotating column rotates, it will drive the cushion to rotate up to 90°. In this way, the purpose of adjusting the angle of the patient's head according to the doctor's needs is achieved by adjusting the angle of the cushion.

[0004] However, there are still the following drawbacks that need to be addressed: When dealing with teeth deep in the upper jaw, the head needs to be tilted back all the time, but the elderly, children, and people with bad cervical vertebrae cannot keep their heads stable. During dental treatment, they may be injured or even suffer medical accidents due to head shaking. Summary of the invention
