DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Example 1, reference Figure 1-Figure 6The present embodiment is a dental appliance, comprising a tubular shell 10, wherein the shell comprises a first shell 10-1 and a second shell 10-2, wherein the interiors of the first shell and the second shell are connected, and the first shell and the second shell are threadedly connected; the end of the first shell away from the second shell is closed and fixed with a hook needle 20, and the end of the second shell away from the first shell is provided with a joint 30 connected with the interior of the second shell: the hook needle is provided with a first water outlet 40 connected with the interior of the first shell, a plurality of second water outlet holes 50 are circumferentially provided on the bottom of the first shell, an annular spring sheet 60 is provided inside the first shell, a fixing ring 70 is provided on the inner side of the annular spring sheet, and a plurality of strip spring sheets 80 are circumferentially provided on the fixing ring, wherein the annular spring sheet, the strip spring sheet and the fixing ring can all be made of spring sheets, and the strip spring sheet is not connected with the fixing ring One end of the annular spring sheet is connected to the outer side of the annular spring sheet, and a sealing body 90 capable of blocking the second water outlet is fixed thereto, wherein the sealing body can be a rubber ring or a rubber block arranged corresponding to the second water outlet. During manufacturing, the side of the first shell on which the hook is arranged can be arranged to be a spherical surface, and the end of the sealing body close to the hook is located at the edge of the spherical surface; a support rod 100 is arranged in the first shell, one end of the support rod passes through the fixing ring and is fixed with a sealing block 110 capable of blocking the first water outlet, and a strip support plate 120 is arranged in the second shell, and the other end of the support rod is against the strip support plate, and the fixing ring is fixed on the sealing block. During manufacturing, a nut can be embedded in the sealing block, and the support rod is threadedly connected to the nut; a blocking flange 100-1 is circumferentially arranged on the support rod, and the fixing ring is clamped between the blocking flange and the sealing block.

[0018] When the dental appliance is used, the connector is connected to a water pipe or other water supply device. Figure 4 In the original state, the second water outlet is blocked by the blocking body, and water can pass through the first shell and the inside of the second shell and then be discharged through the first water outlet. This method is suitable for accurately flushing the hook needle operation part; during the operation, if the hook needle cleans a lot of debris and accumulates near the hook needle operation part, the first shell and the second shell can be tightened so that the strip support plate squeezes the support rod downward to drive the blocking block to move down and block the first water outlet. During the downward movement of the blocking block, the strip spring piece deforms and pulls the annular spring piece to flip and move closer to the inside, so that the blocking body rotates with the bottom end as the center, so that the water flow can enter the second water outlet above the blocking body, so that the area near the hook needle operation part can be flushed; in this way, flushing operations can be performed when using the hook needle to clean teeth, and there is no need to frequently switch tools, which is more convenient to use; In the above embodiments, the first shell and the second shell may also be connected in other ways, as long as the first shell and the second shell can achieve the function of relative movement and relative stillness when moving to a predetermined position; in the above embodiments, a valve on a water supply device or a water pipe may be used to control the water flow; a valve may also be set on the second shell to control the water flow, which is well known to those skilled in the art and will not be described in detail here; the annular spring piece may also be composed of multiple arc-shaped spring pieces, and there may be spacing between adjacent arc-shaped spring pieces.

[0019] As a preferred embodiment: there are two strip support plates, which are cross-arranged, and the intersection position is set to form a circular baffle 120-1, and the support rod is against the circular baffle; in actual production, it is preferred to gradually increase the diameter of the shell from one closed end to the other end to facilitate operation by medical staff.

[0020] It is understandable that in the above embodiment, only one housing and a first water outlet may be provided to realize the flushing function, but compared with the method of providing the second water outlet, the operating function is relatively simple.

[0021] Embodiment 2: Embodiment 2 has substantially the same structure as Embodiment 1, except that: the first water outlet is arranged at one closed end of the shell and corresponds to the hook needle.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
