The second is the "large punching area mode". Please refer to Figures 3 and 5. If you want to use this mode, the user can shift the control 3 (to the right in the direction of the figure in Figure 5). The adjustment positioning portion 34 of the adjustment control 3 can be engaged with the adjustment positioning portion 17 of the handle 1 in a second position (the position farthest from the punching head 2 in the third figure); The plurality of water injection holes 312 of the adjustment control 3 are in communication with the corresponding water channel 13 in the opposite direction, so that the water liquid from the water inlet pipe 5 can pass through the plurality of water injection holes 312, and the plurality of water inlets 14 Flowing into the plurality of front water channels 13 and passing through the plurality of rear water channels 21 to make the nozzles 22 of the punching head 2 There are water column sprays, which can improve the tooth area of the tartar that can be cleaned per unit time, shorten the operation time of the teeth, and achieve the effect of effectively improving the efficiency of tooth cleaning. In addition, by the arrangement of the plurality of leakage preventing members 33, the degree of adhesion when the water injection hole 312 is opposed to the front water channel 13 can be improved, and the water liquid can be prevented from leaking when passing through the plurality of water inlets 14.

The third is the "small rushing area mode". Please refer to Figures 3 and 6. If you want to use this mode, the user can move the adjustment control 3 (to the left in the direction of the figure in Figure 5). The adjustment positioning portion 34 of the adjustment control 3 can be engaged with the adjustment positioning portion 17 of the handle 1 in a third position (the position closest to the punching head 2 in the third figure); The plurality of water injection holes 312 of the adjustment control 3 are only partially in communication with the front water channel 13 , and the remaining water injection holes 312 are not in position communication with the front water channel 13 , so that the water from the water inlet pipe 5 can only flow to the front stage. The water injection hole 312 of the waterway 13 is connected in parallel with the water channel 21, and the corresponding nozzle 22 of the punching head 2 is sprayed with water column, so the punching area of the mode will be small, but the adjustment is not adjusted. In the case of the water injection strength of the water pipe 5, the strength of the water column ejected from the nozzle 22 of the punching head 2 can be relatively increased, and it is suitable for use in cleaning the local slit.

Therefore, the red teeth device of the present invention can provide different operation modes, and adjust the number of water jets to be sprayed, thereby generating different punching areas to meet different punching requirements.

It should be noted that the plurality of waterways of the red teeth device of the present invention are not limited to the upper and lower setting modes shown in FIG. 2, and in other embodiments, the plurality of waterways may also be arranged side by side. (Fig. 7), in order to change the arrangement direction of the plurality of nozzles 22 and to change the operation mode of the adjustment control 3 (from the original up and down to the left and right); or the plurality of waterways may be interlaced in the space. The various types of the nozzles 22 are sprayed up and down, and the nozzles 22 are still sprayed with water, and the like, which can be understood and adjusted by those skilled in the art, and will not be described again.

In summary, the red teeth device of the present invention has a plurality of water channels, and can be controlled to select the water channels to be discharged simultaneously or only a part of the water channels (ie, the area of the teeth can be adjusted). When the water channels are simultaneously discharged, the area of the tartar which can be cleaned per unit time is increased, the operation time of the teeth is shortened, and the efficiency of cleaning the teeth is improved; on the other hand, when only part of the water channel is out of water, When the influent strength is adjusted, the strength of the ejected water column is relatively increased, and it is suitable for cleaning the tartar against the local slit. Therefore, the red teeth device of the present invention can not only effectively solve the problem of poor efficiency of conventional dental cleaning, but also provide different punching modes for selection, so that it has the effect of improving the practicability of the product.

While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention. The technical scope of the invention is protected, and therefore the scope of the invention is defined by the scope of the appended claims.
