Description

[Detailed Description of the Invention] The present invention relates to a dental tartar remover driven by compressed air.

Conventionally, a non-drive type hand scaler 1 or a drive type electric ultrasonic scaler is used to remove tartar, plaque, etc.

However, the former type of hand scaler has a sharp cutting edge, so there is a risk of scratches on the tooth surface, lacerations to the cheeks and tongue in the oral cavity, etc., and the treatment efficiency is poor, causing fatigue for the operator.

It is also known that the latter electric ultrasonic scaler has a tip that vibrates minutely and can efficiently remove tartar, plaque, and the like.

However, since it is necessary to bring the electrical part close to the oral cavity, there is a risk of danger to the patient in the event of an electrical system accident.

Moreover, it requires a large number of electrical parts for frequency control and is expensive.

In view of the above points, the present invention is a low-priced and highly safe dental calculus.
The present invention provides a compressed air-driven dental tartar remover that can efficiently remove plaque and the like, and will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view of an embodiment of the present invention.

The casing 1 has a vibration chamber 2 consisting of a cylindrical cavity,
An exhaust port 5 is provided at the rear end to communicate the vibration chamber 2 and the rear exhaust chamber 15, and a transmission shaft 6, which is a transmission means for transmitting vibration, is connected to the center of the tip. A chip connecting part 7 is provided, which is a connecting part suitable for the connecting method of the chip 21 (in this embodiment, it is a screw connection) to connect the chip 21, which is a working tool for removing the chip 21, and An anti-twisting pin 8 is joined to the front surface of the casing 1, and a blow hole 4 that connects the vibration chamber 2 and the intake chamber 14 on the outer periphery is located at an angle oblique to the inner wall of the vibration chamber 2. A hollow cylindrical rotor 3 is installed inside the vibration chamber 2.

In order to prevent vibrations from being transmitted to the outer cover 9 and the hose connector 10, an O-ring, which is an elastic support means, is attached as follows.

The O-ring 19 attached to the anti-twist pin 8 supports the anti-twist pin 8 and the casing 1 in the axial direction, and the O-ring 18 attached to the casing 1 serves as a compressed air seal and support in the circumferential direction.

An O-ring 17 attached to a return prevention device 22 to prevent the casing 1 from being pushed back is an exhaust seal and an axial support, and an O-ring 20 attached to the tip of the cover 9 is the support of the transmission shaft 6 in the circumferential direction.

Next, a hose connector 10 having an intake pipe 11, an intake passage 12, and an exhaust passage 13 is connected to the cover 9 by screwing.

Intake vibrator 11 of the dental tartar remover of the present invention having the above structure
If more compressed air is supplied (the flow of compressed air is shown by arrows), it will be guided to the intake chamber 14 through the hose connector 10 and the intake passage 12 in the cover 9, and the compressed air will be blown into the vibration chamber 2 from the blowing hole 4. An air cushion is generated on the inner wall of the vibration chamber 2, and the rotor 3 floats and begins to rotate.

The rotation of the rotor 3 is transmitted as vibration to the casing 1, and the vibration is further transmitted to the tip 21 via the transmission shaft 6, thereby smoothly removing tartar, plaque, etc., as described above.

Further, the compressed air is exhausted to the atmosphere through the exhaust port 5, the exhaust chamber 15, the muffling filter 16, and the exhaust passage 13.

The pressure of compressed air acting on the rotor 3 of the present invention is
Since the rotor 3 is compressed from the outside, the rotor 3 is expanded by centrifugal force, and damage to the rotor 3 is prevented.

As mentioned above, the dental tartar remover of the present invention has a simple structure, is manufactured with a small number of parts, and is inexpensive, and the vibrating tip enables comfortable, efficient, and safe treatment. .

In implementing the present invention, it is possible to significantly improve the performance by the following two points or by a combination thereof.

(1) The blowing holes are arranged in double rows to increase the flow rate of compressed air and increase the vibration frequency.

(2) A round hole or an arc-shaped exhaust port is provided at a plurality of equal parts apart from the center on the rear end surface of the casing to improve exhaust efficiency and increase the vibration frequency.
