The top surface 80 is formed in a circular shape, and as shown in FIG. 14, a mounting hole 81 through which the receiving port 72 of the switching valve 7 can be inserted and a fixing portion 82 of the receiving port 72 are provided in the center thereof. Further, as shown in FIG. 10, the circumferential surface 83 has a plurality of slits 84 formed at equal intervals in the circumferential direction in the axial direction, and each portion of the circumferential surface is a spring piece 85. A locking claw 86 is provided at the lower end of the piece 85 (see FIG. 14).

As shown in FIG. 11, the hanger member 9 as an accessory part has a cylindrical portion 90 which can be fitted around the coupler 8,
A hanger 9 is provided on one side thereof with a tapered flat surface portion 91 that is projected in the horizontal direction, and is cut out in a substantially U-shape at the tip of the flat surface portion 91 so that the upper end of the grip portion 4 of the lubricator main body 2 can be inserted.
Two are provided.

This dental lubrication device 1 includes an oil lubricator main body 2,
The pipe 5 and the switching valve 7 are connected, and in a mode of use, this is attached to the lubricating oil bottle 10 via the coupler 8 and the hanger member 9.

In use, first, the lubricator main body 2 and the pipe 5 are used.
And connect. In this case, as shown in FIG. 12, the pipe 5 is connected to the lubricator main body 2 with one touch by inserting the insertion port 611 of the grip portion 4 into the receiving port 610 at one end of the pipe 5. Then, the switching valve 7 is connected to the other end of the pipe 5. Also in this case, as shown in FIG. 1, the switching valve 7 is connected to the pipe 5 with one touch by inserting the insertion port 621 of the pipe 5 into the receiving port 620 of the switching valve 7.
As a result, the lubricator main body 2, the pipe 5, and the switching valve 7 are connected.

When this is subsequently connected to the lubricating oil bottle 10, as shown in FIG. 13, first, the coupler 8 is attached around the lubricating oil ejection port 11 on the upper portion of the lubricating oil bottle 10. The coupler 8 is covered over the spouting port 11 of the lubricating oil, and the circumferential surface of the coupler 8 is locked by the locking ring 12 on the upper part of the lubricating oil bottle 10.
By pushing it upwards, as shown in FIG. 14, the peripheral surface of the coupler 8 is opened to the outside of the locking ring 12 by its spring piece 85, and the locking claw 86 at the lower end of the peripheral surface lowers the locking ring 12 (cross section). At the same time when the coupler 8 is inserted into the locking ring 1, the peripheral surface of the coupler 8 is elastically restored and the locking claw 86 is locked.
2 is elastically locked. As a result, the coupler 8 is attached to the top of the lubricating oil bottle 10 on the lubricating oil ejection port 11. Incidentally, the hanger member 9 is attached to the coupler 8 together with the attachment of the coupler 8. In this case, the hook member 9 is attached to the coupler 8 only by externally fitting the cylindrical portion 90 of the hanger member 9 around the coupler 8. Next, the switching valve 7 connected to the pipe 5 is connected to the ejection port 11 of the lubricating oil bottle 10. In this case, the pipe of the switching valve 7 is closed in advance by the cock 71, and the switching valve 7 is closed.
The receiving port 72 is inserted into the attachment hole 81 of the coupler 8 and is inserted into the ejection port 11 of the lubricating oil bottle 10, and the ejection port 11 is pressed. This pressed state is retained by the switching valve 7 being retained by the fixing portion 82 of the coupler 8, whereby the lubricating oil is spouted from the spouting port 11 of the lubricating oil, and this is flowed into the switching valve 7. It Since the pipe of the switching valve 7 is closed by the cock 71 in advance, the flow of the lubricating oil ejected by the switching valve 7 is closed. As shown in FIG. 1, the lubricator main body 2 can be hung on the hanger member 9 by inserting the grip portion 4 of the lubricator main body 2 into the hanger 92 of the hanger member 9.

Next, the lubrication and cleaning of the handpiece by the dental lubrication device 1 will be described. First, the handpiece is connected to the lubricator main body 2. In this case, place the lubricating oil bottle 10 on a table, workbench or floor,
Holding the handpiece in one hand and holding the lubricator main body 2 in the other hand, the nozzle 31 of the head portion 3 is connected to the lubrication portion (bearing, chuck portion, etc.) of the handpiece.
After connecting the handpiece to the lubricator main body 2, the cock 71 of the switching valve 7 connected to the lubricating oil bottle 10 is turned to open the pipeline. As a result, the lubricating oil spouted from the lubricating oil bottle 10 through the lubricating oil spouting port 11 flows through the pipe 5 from the pipe line of the switching bolt 7 and is closed by the opening / closing valve 32 of the lubricator main body 2. In this way, when the operation button 33 of the lubricator main body 2 is pressed with a fingertip to open / close the open / close valve 32, the pipeline of the open / close valve 32 is opened, and the lubricating oil flows from the pipe 5 to the lubricating oil passage 30 of the head portion 3.
And is lubricated inside the handpiece through the nozzle 31 on the extension thereof.

As described above, according to the above embodiment, the lubricating oil bottle 10 is provided with the separate lubricator main body 2, the pipe 5, and the coupler 8.
Connect the nozzle 31 of the lubricator main body 2 to the lubrication part of the handpiece, and press the operation button 33 provided on the lubricator main body 2 to lubricate the lubricating oil to the lubrication part of the handpiece. Since the heavy lubricating oil bottle 10 filled with the lubricating oil is not held in the hand, it is possible to lubricate the lubrication portion of the handpiece with the lightweight lubricator main body 12 which is easy to hold in the hand. It is possible to efficiently carry out these operations by reducing the oiling and cleaning operations.

[0022]

As described above, according to the present invention,
Using the lubricating oil bottle and a separate manual lubricator body,
The nozzle is connected to the lubrication part of the handpiece, and the lubricating oil is ejected by operating the operation button provided on the lubricator and sprayed onto the lubrication part of the handpiece, so a heavy bottle filled with lubricating oil. It is possible to lubricate the lubrication part of the handpiece with a lubricator with good operability without holding the hand, reducing the lubrication and cleaning work of the handpiece,
Workability can be improved.
