[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0021] Reference Figure 1 and Figure 2As shown, a dental bur is a treatment tool used by dentists, which consists of a needle 12 and a needle handle and can be inserted into a high-speed or low-speed mobile phone for use. After the existing dental burs are used, some severely damaged burs will be scrapped, while some burs can be used again after disinfection. However, most of the existing dental burs do not have this function, which makes the subsequent disinfection process more troublesome and the degree of disinfection cannot be guaranteed. In order to solve this problem, a dental bur with a self-cleaning function is proposed, including a bur body 1, the bur body 1 includes a needle 12 and a needle tube 11 fixedly connected in sequence, a first thread 111 is distributed on the outer circumference of the needle tube 11, and a cleaning member 2 is provided on the needle tube 11, the cleaning member 2 includes a cleaning sleeve 21 that slides vertically along the extension direction of the needle tube 11, and the bottom inner wall of the cleaning sleeve 21 is provided with a cleaning member that is aligned with the first thread 1 11, and the cleaning sleeve 21 is hollowly arranged, and a plurality of cleaning cottons 22 and groove cleaning blocks 23 are sequentially spaced on the inner wall of the cleaning sleeve 21, and a cleaning groove 211 for the needle 12 to be inserted is formed on the side where the plurality of groove cleaning blocks 23 are close to each other; the needle body 1 is formed by the combination of the needle 12 and the needle tube 11, and the setting of the cleaning sleeve 21 in the cleaning member 2 can achieve the purpose of cleaning the needle 12 and the needle tube 11 synchronously, and with the cooperation of the second thread 212 in the cleaning sleeve 21 and the first thread 111 on the outer periphery of the needle tube 11, the cleaning sleeve 21 can be made to slide in an orderly manner to clean the needle 12 part, and with the sliding of the cleaning cotton 22 and the groove cleaning block 23, the purpose of completely and effectively cleaning the needle 12 part can be guaranteed, so that the whole cleaning and disinfection process is more complete.

[0022] It should be noted that since the size specifications of the needle 12 may be different from those of the needle tube 11, in order to solve the above problem, in this embodiment, the cleaning cotton 22 and the groove cleaning block 23 are made of elastic material. The purpose of this arrangement is to ensure that the cleaning cotton 22 and the groove cleaning block 23 are clearance-fitted when they are attached to the needle tube 11. When the size of the needle 12 is larger than the size of the needle tube 11, when the cleaning sleeve 21 slides to the needle 12, the cleaning cotton 22 and the groove cleaning block 23 will be compressed with the needle 12 and always maintain a state of attachment to the needle 12, thereby ensuring that the needle 12 can be cleaned and disinfected.

[0023] Furthermore, a plurality of chip grooves 121 are spaced apart on the outer peripheral surface of the needle 12, and the spacing between the chip grooves 121 and the groove cleaning block 23 is the same; the arrangement of the groove cleaning block 23 can achieve the purpose of cleaning and disinfecting the chip groove 121, and the groove cleaning block 23 extends into the chip groove 121 and slides along the chip groove 121.

[0024] It should also be noted that in order to ensure that the second thread 212 of the cleaning sleeve 21 can cooperate with the first thread 111 on the outer periphery of the needle tube 11, and that the cleaning sleeve 21 is relatively limited during the sliding process, in this embodiment, the cleaning sleeve 21 is located on one side of the second thread 212, and a limiting boss 2121 is formed inwardly for circumferentially limiting the cleaning sleeve 21, and the second thread 212 is arranged on the inner circumferential surface of the limiting boss 2121; the setting of the limiting boss 2121 can achieve relatively stable sliding of the cleaning sleeve 21, and another function of the limiting boss 2121 is to prevent the cleaning sleeve 21 from sliding over the stroke.

[0025] The other end of the needle tube 11 is used for inserting into a high-speed or low-speed handpiece for use. During use, the provision of the cleaning sleeve 21 will not affect the use of the needle.

[0026] It is worth mentioning that, referring to Figure 3 As shown, the cleaning cotton 22 and the groove cleaning blocks 23 are distributed in sequence and at intervals, and a cleaning groove 211 for the needle tube 11 or the needle 12 to slide into is formed between the plurality of groove cleaning blocks 23, and the head area of ​​the groove cleaning block 23 is protruding so as to be able to fit into the chip removal groove 121 of the needle 12.

[0027] In addition, the arrangement of the cleaning cotton 22 and the groove cleaning block 23 is to ensure better orderly cleaning and disinfection of the needle 12, and the cleaning cotton 22 may also contain some disinfectant to ensure the integrity of the disinfection.

[0028] In particular, the cleaning sleeve 21 is also detachably connected to the entire needle. The detachable connection can ensure that the cleaning sleeve 21 is more convenient to disassemble and replace, and can also ensure that the entire device is more practical.

[0029] Furthermore, the cleaning sleeve 21 in the conventional setting can also facilitate the operator to grasp the entire needle body 1, thereby achieving another effect.

[0030] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
