Description

A water-passing structure and a dental scaler handle containing the same

technical field

The invention relates to the field of dental medical instruments, in particular to a water-passing structure and a dental scaler handle containing the same.

Background technique

The water passage structure in the traditional handle uses metal connectors to connect the water supply equipment with the inner flow channel of the main rod. The metal connector is rigid as a whole, which will damp the power of the transducer in the handle, which will reduce the energy conversion. The power of the transducer is also prone to the problem of resonance between the shell and the transducer.

Contents of the invention

The technical problem to be solved by the present invention is to provide a water-passing structure and a dental scaler handle containing it, so as to overcome the above-mentioned deficiencies in the prior art.

The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a water passage structure, including a water connector, a main rod, a hose and a support pipe, one end of the hose is connected to the water connector, and the other end of the hose is connected from the lower end of the main rod Extending into the flow channel in the main rod, the hose is located in the lumen of the flow channel and is provided with a support tube along the water flow direction, and the outer tube wall of the support tube is in close contact with the inner tube wall of the hose.

The beneficial effects of the present invention are: the traditional metal connectors are replaced by water joints, hoses and support pipes, and assembled in the above manner, so that only the hoses are used as water passages at positions other than the cooperation between the hoses and the support pipes , Compared with metal, it is softer, which reduces the damping of the power of the transducer, and also overcomes the problem of resonance between the shell and the transducer, and is also conducive to improving the assembly efficiency of the handle.

On the basis of the above technical solutions, the present invention can also be improved as follows.

Further, the length of the hose extending into the flow channel is 15mm-24.5mm.

Further, the length of the support tube is 20mm-30mm.

Further, an annular protrusion is provided on the outer wall of the end of the hose extending into the flow channel, and the annular protrusion is close to the wall surface of the flow channel.

The further beneficial effect of adopting the above is that the addition of the annular protrusion can reduce the contact area between the hose and the flow channel, thereby further reducing the damping of the power of the transducer.

Further, the number of annular protrusions is two.

The further beneficial effect of adopting the above is that the damping of the transducer can be maintained in an optimum range while ensuring no water leakage as much as possible.

Further, the Vickers hardness of the hose is 60±5 degrees.

Further, the hose is made of silicone material.

Further, it also includes a collar, and the part where the hose is connected to the water joint is covered with a collar.

A dental scaler handle includes a water passage structure.

Description of drawings

Fig. 1 is the structural representation of water passage structure described in the present invention;

Fig. 2 is a structural schematic diagram of the handle of the present invention.

In the accompanying drawings, the list of parts represented by each label is as follows:

1. Water connector, 2. Main rod, 3. Flexible hose, 310, annular protrusion, 4. Support pipe, 5. Collar, 6. Shell.

Detailed ways

The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

Example 1

As shown in Figure 1, a water connection structure includes a water joint 1, a main rod 2, a hose 3 and a support pipe 4, and one end of the hose 3 is connected to the water joint 1. Usually, it is preferable to connect the water joint 1 The interface end of the hose 3 is inserted into the hose 3, and the interface end of the water joint 1 is connected to the pipe wall of the hose 3 by using the elasticity of the hose 3. The other end of the hose 3 extends from the lower end of the main rod 2 to the main In the flow channel in the rod 2 , a support tube 4 is arranged in the lumen of the hose 3 in the flow channel along the water flow direction, and the outer tube wall of the support tube 4 is in close contact with the inner tube wall of the hose 3 .

Example 2

As shown in Figure 1, this embodiment is a further improvement on the basis of Embodiment 1, and the specific content is as follows:

Usually, the length of the hose 3 extending into the flow channel is 15mm-25.4mm, preferably 25.4mm, and the length of the support tube 4 is 20mm-30mm, preferably 28mm.

Example 3

As shown in Figure 1, this embodiment is a further improvement on the basis of Embodiment 2, and the specific content is as follows:
