Referring to fig. 1 and 2, some embodiments of the present application provide a position adjustment mechanism that allows the lifting of the mouthrinse S to be synchronized with the lifting of the dental chair C. The dental chair is usually designed in combination with a treatment device as a dental chair device, which may comprise, for example, in addition to the dental chair, a tray, a treatment light, and a housing containing a frame for controlling the dental chair and the corresponding components. The housing of the dental chair apparatus is usually integrated with a dental chair C, and the adjustment structure of the dental chair C is basically provided in the housing of the dental chair apparatus. Some dental chairs are designed to be driven up or down to match the treatment of the doctor, however, the height of the rinsing spittoon S is often fixed, too close to the spittoon for the patient' S head when the chair is in the low position, making it uncomfortable to feel too close to the dirt; when the dental chair is in the high position, the distance between the gargling spittoon and the head of a patient is too large, and water is easy to splash out of the gargling spittoon S during gargling.

To this end, some embodiments of the application provide a position adjustment mechanism for the mouthrinse S such that the fitting of the mouthrinse S through the housing of the dental chair device onto the lifting mechanism of the dental chair can adjust the height position of the mouthrinse S as the height of the dental chair is adjusted to match the height position of the dental chair C.

As shown in fig. 1, 2, in the embodiment of this application, can provide a mount in order to support or bearing gargle spittoon for gargle spittoon S, link firmly stand 16 below the mount, stand 16 cross-under is in the setting in the sliding sleeve 8 of box for thereby the stand can slide in sliding sleeve 8 and make the up and down application of stand 16 can drive the mount and then drive gargle spittoon S up-and-down motion. In other embodiments of the present application, the post 16 can be secured directly to the mouthpiece to support the mouthpiece without a mount.

In order to achieve a synchronous lifting of the rinsing spittoon S and the dental chair C, the upright 16 is connected to a part which performs a lifting movement via an adjusting linkage 15. In the embodiment shown in fig. 1 and 2, the part that performs the lifting movement is a support plate 14. The bracket plate 14 may be configured to engage and be moved upwardly or downwardly by the ottoman lift mechanism.

In the embodiment shown in fig. 1 to 4, the lift mechanism of the dental chair may include a motor 12, a fixed end 121 of the motor 12 is pin-connected to a frame in a housing of the dental chair apparatus so that the motor 12 as a whole may rotate with the fixed end, and a movable end 122 of the motor 12 is connected to the lift push rod 11 so that the lift push rod 11 may be driven to rotate, which may be connected to a middle portion of the lift push rod 11, in particular. The fixed end 121 may be disposed on the motor housing, the movable end 122 may be disposed on the motor shaft, the first end 112 of the lifting push rod 11 is pivotally connected to the frame so as to rotate around the frame, and the second end 113 is engaged with the frame plate 14, for example, slidably or rollably engaged with the bottom surface of the frame plate 14, as shown in fig. 3 and 4, includes a roller so as to rollably engage with the bottom surface 141 of the frame plate 14, or engaged with the side surface of the frame plate 14 as in other embodiments. The mounting plate 14 is also constrained to fit on an upright riser rail so that the mounting plate 14 is constrained to move up and down the riser rail. The lifting rail may be a pair or a plurality of lifting rails, and may be, for example, a pair of

lifting rails

13A, 13B as shown in fig. 1 and 2.

An adjusting connecting rod 15 is further fixed on the support plate 14, the upper part of the adjusting connecting rod 15 is fixedly connected to the upright post 16 as described above, the upright post 16 is fixedly connected to the fixed frame or directly fixed to the lower part of the mouth wash basin, a sliding sleeve 8 is fixedly arranged on the box body of the dental chair device, for example, the top surface of the box body, the sliding sleeve 8 has a diameter larger than that of the upright post 16, so that the upright post 16 threaded in the sliding sleeve 8 is arranged to be matched in the sliding sleeve 8 and can move up and down along the sliding sleeve 8.

When the movable end 122 of the motor 12 moves away from the fixed end 121, for example, when the motor rod gradually extends out of the motor sleeve, the fixed end 121 rotates to drive the lifting push rod 11 to rotate clockwise around the pinned end 112 thereof, so as to drive the bracket plate 14 to move upward along the lifting guide rail 13, and then the dental chair is lifted from the low position to the high position. In the process, the bottom surface 141 of the support plate 14 is pushed by the end 113 of the lifting push rod 11 to move upwards along the guide rail, so that the adjusting connecting rod 15 is driven to move upwards, the adjusting connecting rod 15 drives the fixed frame upright post 16 to move upwards along the sliding sleeve 8, so that the mouth rinsing spittoon and the dental chair are driven to rise together until the first state of the second height position, namely the high position, is achieved. When the movable end 122 of the motor 12 moves towards the fixed end 121, for example, when the motor rod retracts the motor sleeve, the moving directions of the components are opposite, the bottom surface 141 of the bracket plate 14 is no longer supported by the end 113 of the lifting push rod 11, and therefore starts to fall down, so as to move upwards along the guide rail, and the fixed frame upright 16 moves downwards along the sliding sleeve 8, so as to drive the tooth wash basin to descend together with the dental chair until the tooth wash basin is in the second state of the first height position, namely the low position.

In some embodiments of the present application, the lift rail of the dental chair apparatus is a linear bearing.

In some embodiments of this application, adjust connecting rod 15 and be one end threaded adjusting screw, adjust the connecting rod through this screw thread and the stand in set up the screw-thread fit in to realize stand and the whole height-adjustable who adjusts connecting rod 15, thereby adjust the relative position of rinsing spittoon S and dental chair C.

In some embodiments of the present application, a damper 151 is connected to an end of the adjusting link 15 remote from the upright, through which the adjusting link 15 is connected to the bracket plate 14, to cushion the pressure on the bracket plate 14 and the lifting mechanism when the rinsing spittoon falls.

The solution that this application provided machine dress formula dental equipment colludes at present and colludes glene and too little or too big unreasonable structure of patient head interval, the relative position of colluding glene S and dental chair C can also be adjusted to the structure that some embodiments of this application provided simultaneously for it is more convenient to use.
