DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The above and other technical features and advantages of the present utility model will be described in more detail below with reference to the accompanying drawings.

[0024] This embodiment provides a technical solution: a resin filler, as Figures 1 - 4 shown, including a tube body 1 and a filling end 2.

[0025] In a specific implementation, as Figures 1 - 3 shown, the filling end 2 is arranged at the end of the tube body 1. The filling end 2 includes an adjusting tube 201 and a nozzle 202. The nozzle 202 is arranged at one end of the adjusting tube 201. A receiving cavity 3 is formed in the filling end 2. A discharge groove 4 is formed between the end of the receiving cavity 3 and the end of the nozzle 202. A through hole is formed between the receiving cavity 3 and the other end of the nozzle 202. One end of the adjusting tube 201 passes through the through hole and is arranged in the receiving cavity 3. The adjusting tube 201 is communicated with the nozzle 202. Therefore, resin can be introduced into the filling end 2 and sprayed out to facilitate filling the tooth defect area. After that, the end of the nozzle 202 can be used for leveling. It is convenient and fast to use. The adjusting tube 201 and the tube body 1 are connected by a connecting elbow 5. A communicating tube 13 is installed at one end of the tube body 1. Resin can be conveniently injected through the communicating tube 13 and a connecting tube.

[0026] Further, a retaining ring 6 is welded to the outer side of one end of the adjusting tube 201. The retaining ring 6 is clamped in the receiving cavity 3. The retaining ring 6 can prevent the separation between the nozzle 202 and the adjusting tube 201.

[0027] Furthermore, a current-limiting sheet 8 with discharge holes 7 evenly formed at the edge is welded at a position near the spraying end of the discharge groove 4. A current-limiting rod 9 is welded to the current-limiting sheet 8. A connecting tube 14 is welded to one end of the adjusting tube 201. The connecting tube 14 is clamped in the current-limiting rod 9. After the resin enters the connecting tube 14 through the adjusting tube 201, the flow path is restricted by the current-limiting rod 9. A plurality of spraying inclined grooves 10 are evenly formed on the outer side wall of the connecting tube 14. A plurality of discharge inclined grooves 11 corresponding to the spraying inclined grooves 10 are evenly formed on the inner wall of the discharge groove 4. The resin can be evenly sprayed to each edge position of the tooth defect position with the end of the nozzle 202 as the center by passing through the spraying inclined grooves 10 and the discharge inclined grooves 11 in sequence.

[0028] Further, an expansion ring groove 12 is formed on the inner wall of the discharge groove 4. The distance between the regulating pipe 201 and one end of the inner wall of the accommodating cavity 3 is equal to the distance between the ejection inclined groove 10 and the expansion ring groove 12. At the same time, the distance between the current-limiting rod 9 and the ejection inclined groove 10 is greater than the distance between the ejection inclined groove 10 and the expansion ring groove 12. When the regulating pipe 201 is pushed towards the spray head 202, the regulating pipe 201 and the outer retaining ring 6 can move along the accommodating cavity 3. At the same time, the connecting pipe 14 can move along the current-limiting rod 9. After the retaining ring 6 contacts the inner wall of the accommodating cavity 3, the ejection inclined groove 10 can be aligned with the expansion groove. At the same time, the solid part of the connecting pipe 14 can block the discharge inclined groove 11. Therefore, when resin is injected at this time, the resin can enter the expansion ring groove 12 through the ejection inclined groove 10. Subsequently, the resin can pass through the discharge holes 7 on the current-limiting sheet 8 and be ejected from the spray outlet of the spray head 202. At this time, the resin is completely ejected from one point. Generally, spraying from the central position first and then adjusting and controlling the spraying of the edge position can achieve the effect of full filling. Therefore, by adjusting the position between the spray head 202 and the regulating pipe 201, the spraying mode of the resin can be controlled, so that the spraying mode can be flexibly controlled according to requirements.

[0029] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
