[0023] The technical solution of this application will now be described with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0024] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0025] Furthermore, the term "perpendicular" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately perpendicular. The two components described as "perpendicular" do not have to be absolute straight lines or planes; they can be approximately straight lines or planes. From a macroscopic perspective, if the overall direction of extension is a straight line or plane, the component can be considered a "straight line" or "plane".

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0027] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Please see Figure 1 This application provides a cleaning device 100, including a handle 10 and a cleaning component 20. The cleaning component 20 includes a connecting portion 21 and a head 22 that are interconnected. The connecting portion 21 is detachably connected to the handle 10 to facilitate the replacement of the cleaning component 20 on the handle 10.

[0029] Please see Figure 2 The head 22 includes an inclined surface 2201 and a stop surface 2202. The inclined surface 2201 guides the head 22 into the root canal to prevent it from being too large to be inserted or from bumping into the tooth. The stop surface 2202 removes foreign objects from the root canal, thereby cleaning it. The end of the head 22 away from the connector 21 has a smooth surface 2203 to prevent the head 22 from injuring the patient.

[0030] In use, the operator holds the handle 10, inserts the head 22 into the root canal, and then holds the handle 10 to remove the head 22 from the root canal, causing the stop surface 2202 to remove foreign objects from the root canal, thereby cleaning the root canal. Compared to cleaning impurities by rotating a root canal file, which can easily enlarge the root canal, inserting the cleaning device 100 into the root canal to remove foreign objects from inside the root canal is less likely to cause enlargement of the root canal.

[0031] In some embodiments, the inclined surface 2201 is a conical surface. During the insertion of the head 22 into the root canal, the cross-section of the head 22 gradually increases to remove foreign objects attached to the inner wall of the root canal.

[0032] In some embodiments, the inclined surface 2201 may have other shapes, such as polygonal or semi-conical, and this application does not limit this.

[0033] In some embodiments, there are multiple inclined surfaces 2201 and stop surfaces 2202, and each inclined surface 2201 and each stop surface 2202 are connected to form a ridge 221. The head 22 has one or more ridges 221, which are continuously arranged, and a recess 222 is formed between each pair of adjacent ridges 221. The ridges 221 can scrape off foreign objects from the inner wall of the root canal, and the recesses 222 can accommodate foreign objects to clean the root canal and remove foreign objects from the inner wall of the root canal.

[0034] In some embodiments, the stop surface 2202 and the inclined surface 2201 form an angle α, where 30° < α < 150°.

[0035] In the illustrated embodiment, the included angle α is 100°.

[0036] In some embodiments, the smooth surface 2203 is arc-shaped or planar, and the smooth surface 2203 and the inclined surface 2201 are smoothly transitioned to avoid accidental injury to the patient.

[0037] Please see Figure 1 In some embodiments, the head 22 is bent to adapt to multi-angle working needs, making it convenient for operators to hold the handle 10 to clean the root canal.

[0038] In some embodiments, the cleaning device 100 includes two cleaning components 20, which are detachably connected to both ends of the handle 10, allowing two cleaning components 20 to be mounted on one handle 10. The two cleaning components 20 may be of the same type or different types, and this application does not impose any restrictions on this.

[0039] Please see Figure 3 and Figure 4 In some embodiments, the handle 10 includes a connecting rod 11 and a locking member 30. The connecting rod 11 is provided with a positioning groove 1101, and the connecting part 21 is inserted into the positioning groove 1101. The locking member 30 is connected to the connecting rod 11 to fix the connecting part 21 to the connecting rod 11.

[0040] The connecting rod 11 accommodates the connecting part 21 through the positioning groove 1101 to position the relative position of the cleaning component 20 and the handle 10. The cleaning component 20 is fixed to the handle 10 by the locking member 30 to install the cleaning component 20.

[0041] Please see Figure 5 and Figure 6 In some embodiments, the connecting rod 11 is provided with a slot 1102, which penetrates the bottom of the positioning groove 1101; the connecting part 21 includes a main body 211 and a locking block 212, the main body 211 is disposed in the positioning groove 1101, and the locking block 212 is inserted into the slot 1102 to restrict the connecting part 21 from rotating relative to the connecting rod 11.

[0042] The main body 211 is cylindrical, and the locking block 212 is elongated. The locking block 212 is accommodated by the locking groove 1102 to prevent the connecting part 21 from rotating relative to the connecting rod 11.

[0043] In some embodiments, the connecting rod 11 includes a clamping part 111 and a positioning groove 1101 is provided in the clamping part 111; the locking member 30 is sleeved on the clamping part 111 so that the clamping part 111 clamps the connecting part 21 in the positioning groove 1101, thereby preventing the cleaning member 20 from disengaging from the handle 10 or rotating relative to the handle 10.

[0044] Please combine Figures 3 to 6 In some embodiments, the clamping part 111 includes a first sidewall 1111 and a second sidewall 1112, and a positioning groove 1101 is formed on the first sidewall 1111 and the second sidewall 1112. The first sidewall 1111 and the second sidewall 1112 are spaced apart to form a gap 111a, and the gap 111a communicates with the positioning groove 1101.

[0045] When the locking member 30 is fitted onto the clamping part 111, the first side wall 1111 and the second side wall 1112 move closer to each other, causing the gap 111a to gradually decrease, thereby clamping and fixing the connecting part 21 with the first side wall 1111 and the second side wall 1112.

[0046] In some embodiments, the outer surface of the clamping part 111 is provided with a first thread 11111, that is, the first thread 11111 is provided on the outer surface of the first sidewall 1111 and the second sidewall 1112, and the inner wall of the locking member 30 is provided with a second thread 31.

[0047] The inner wall of the locking member 30 is inclined. When the locking member 30 moves close to the connecting rod 11 and rotates relative to the connecting rod 11, the first thread 11111 is threaded to the second thread 31, that is, the locking member 30 is tightened to the outer surface of the first side wall 1111 and the second side wall 1112, so that the inner wall of the locking member 30 pushes the first side wall 1111 and the second side wall 1112 closer together, so that the gap 111a gradually becomes smaller, thereby clamping and fixing the connecting part 21 by the first side wall 1111 and the second side wall 1112.

[0048] In some embodiments, the cleaning member 20 is provided with a protruding ring 23, which is configured to abut against the inner wall of the locking member 30 when the locking member 30 is engaged with the clamping part 111, so as to prevent the connecting rod 11 from shaking relative to the locking member 30 and to ensure that the connecting rod 11 is stably connected to the rod part.

[0049] In some implementations, the inner circumferential surfaces of the first sidewall 1111 and the second sidewall 1112 are both arc-shaped, making the positioning groove 1101 cylindrical to fit the cylindrical body 211.

[0050] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
