Description

Technical Field

[0001] The utility model relates to the technical field of dental medical instruments, in particular to a dental contra-angle handpiece with a detachable water filter structure. Background Art

[0002] Existing dental handpieces mainly include two types: internal water channel and external water channel. Dental contra-angle handpieces with internal water channel are more frequently used, and the design of the internal water channel makes the dental handpiece simpler and more convenient to use. However, when the water source used for the dental handpiece with internal water channel contains impurities, it is easy to cause the internal water channel to be blocked, causing the handpiece to fail to work normally. At this time, the handpiece needs to be completely disassembled to remove the impurities, which is cumbersome and affects work efficiency. At the same time, frequent disassembly to remove impurities will also affect the service life of the handpiece. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a dental contra-angle handpiece with a detachable water filter structure.

[0004] The technical solution to achieve the purpose of this utility model is:

[0005] A detachable water filter structure is arranged in the tail end of a dental handpiece, comprising a water inlet channel arranged inside the handpiece, a water inlet being provided on the water inlet channel, wherein a filter is arranged in the water inlet channel, one end of the filter is connected to the input end of a water delivery pipeline inside the handpiece, and a plug is arranged at the other end.

[0006] The two ends of the water inlet channel are respectively provided with a first sealing member and a second sealing member, so that the water entering the water inlet channel can only enter the water delivery pipeline after passing through the filter element, thereby preventing the liquid entering the water inlet channel from the water inlet from infiltrating into other components of the contra-angle handpiece.

[0007] An annular groove is arranged on the outside of the plug, and the first sealing member is arranged in the annular groove.

[0008] The second sealing element is arranged on the outer wall of the end where the water inlet pipeline is connected to the filter element.

[0009] The water inlet pipeline is also provided with a locking member, which is arranged on one end of the second sealing member away from the water filtering member.

[0010] The utility model also provides a dental contra-angle handpiece, which comprises: the detachable water filter structure as described in any one of the above items.

[0011] The beneficial effects of the utility model are:

[0012] The utility model provides a detachable water filter structure and a dental contra-angle handpiece thereof. The water filter structure is arranged at the tail end of the contra-angle handpiece, and the tail end of the contra-angle handpiece is detachably connected to an electric motor. By arranging a filter in a water inlet channel and arranging a plug at the tail end of the filter, when too many impurities are filtered by the filter, it is only necessary to separate the tail end of the contra-angle handpiece from the electric motor and remove the plug, so that the filter can be taken out of the water inlet channel to remove the impurities, without the need to disassemble the entire contra-angle handpiece to dredge the pipeline. Such an arrangement effectively improves the working efficiency of the contra-angle handpiece, reduces the possibility of disassembly, and can also increase the service life of the contra-angle handpiece. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is a schematic diagram of the structure of a dental contra-angle handpiece according to this embodiment;

[0014] Figure 2 for Figure 1 Enlarged view of part A in the middle;

[0015] In the figure: 1, contra-angle handpiece 2, tail end of contra-angle handpiece 3, plug 4, annular groove 5, first sealing member 6, water inlet 7, water inlet channel 8, filter 9, second sealing member 10, locking member 11, water delivery pipeline. DETAILED DESCRIPTION

[0016] The contents of the present invention are further described below in conjunction with the accompanying drawings and embodiments, but are not intended to limit the present invention. Example

[0017] like Figure 1 As shown, this embodiment provides a dental contra-angle handpiece 1 with a detachable water filtering structure, wherein the tail end 2 of the dental contra-angle handpiece is detachably connected to an external electric motor, and the water filtering structure is arranged inside the tail end 2 of the contra-angle handpiece.

[0018] like Figure 2 As shown, the water filtering structure includes: a water inlet channel 7 arranged inside the mobile phone, a water inlet 6 is provided on the water inlet channel 7, wherein a filter element 8 is arranged in the water inlet channel 7, one end of the filter element 8 is connected to the input end of the water supply pipeline 11 inside the mobile phone, and a plug 3 is arranged at the other end.

[0019] The two ends of the water inlet channel 7 are respectively provided with a first sealing member 5 and a second sealing member 9, so that the water entering the water inlet channel 7 can only enter the water delivery pipeline 11 after passing through the filter 8, thereby preventing the liquid entering the water inlet channel 7 from the water inlet 6 from penetrating into other parts of the dental contra-angle handpiece 1.

[0020] The plug 3 is provided with an annular groove 4 on its exterior, and the first sealing member 5 is provided in the annular groove 4 .

[0021] The second sealing member 9 is arranged on the outer wall of the end where the water inlet pipe 11 is connected to the filter member 8 .

[0022] The water inlet pipeline 7 is also provided with a locking member 10, which is arranged on one end of the second sealing member 9 away from the water filter 8. The locking member 10 enables the water inlet end of the water delivery pipeline to be fixed in the contra-angle handpiece.

[0023] The present embodiment provides a detachable water filtering structure and a dental contra-angle handpiece thereof. When the contra-angle handpiece is used, the tail end 2 of the contra-angle handpiece is detachably connected to an external electric motor. By arranging a filter 8 in the water inlet channel 7 and arranging a plug 3 at the tail end of the filter 8, when too many impurities are filtered by the filter 8, it is only necessary to separate the tail end of the contra-angle handpiece 1 from the electric motor and remove the plug 3, so that the filter 8 can be taken out of the water inlet channel 7 to remove the impurities, without disassembling the entire contra-angle handpiece to clear the pipeline. Such an arrangement effectively improves the working efficiency of the contra-angle handpiece, reduces the possibility of disassembly, and can also increase the service life of the contra-angle handpiece.
