DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1-Figure 5 , an external tooth scaler shown in the figure includes a body 101, a first connecting tube 102 is provided on the body 101, the other end of the first connecting tube 102 is connected to a handle 103 through a second connecting tube 104, and also includes a storage mechanism provided on the body 101 for storing the second connecting tube 104;

[0024] The storage mechanism includes a storage frame 201 fixedly connected to one side of the body 101, a storage tube 202 is rotatably connected between two opposite inner walls of the storage frame 201, two symmetrically arranged storage trays 203 are fixedly connected to the side wall of the storage tube 202, a second connecting tube 104 is wound around the storage tube 202 and located on the side walls of the two storage trays 203, one end of the second connecting tube 104 is connected to the side wall of the storage tube 202, the other end of the second connecting tube 104 penetrates the storage frame 201 and is connected to the handle 103, the first connecting tube 102 is connected to the storage tube 202 through a connecting assembly, a limiting mechanism for limiting the second connecting tube 104 after storage is completed is provided on the storage tube 202, two symmetrically arranged clamping plates 205 are provided on the side wall of the storage frame 201, and the handle 103 is clamped on the two clamping plates 205;

[0025] It should be noted here that: through the setting of the storage mechanism, under the rebound effect of the rebound component and the guiding effect of the two storage trays 203, the second connecting tube 104 is automatically stored, and under the limiting effect of the limiting mechanism, the stability of the storage of the second connecting tube 104 is maintained, thereby avoiding the second connecting tube 104 from being entangled and damaged due to artificial winding, thereby further improving the convenience of use and the safety of storage of the second connecting tube 104, and ensuring the normal use performance of the external dental cleaning machine.

[0026] It is worth noting that: as an existing technology, the specific structure and working principle of the external tooth cleaning machine have been mastered by people in this field, and no further details will be given here.

[0027] See also Figure 3 The connecting assembly shown in the figure includes a connecting hole opened on the side wall of the receiving tube 202, a connecting ring 3 is rotatably connected to the connecting hole, and the other end of the first connecting tube 102 is connected to the connecting ring 3;

[0028] It should be noted here that: the provision of the connection assembly facilitates the first connection pipe 102 and the second connection pipe 104 to be connected.

[0029] Working principle: When using the body 101, first remove the handle 103 from the clamping plate 205 on the storage frame 201, then pull the second connecting tube 104, pull the second connecting tube 104 out of the storage frame 201, and then perform normal oral treatment operations;

[0030] After the use of the body 101 is completed, by pulling the pull plate 407, under the feedback action of the feedback assembly and the guiding action of the two storage trays 203, the second connecting tube 104 is driven to be wound around the side wall of the storage tube 202, thereby realizing automatic storage of the second connecting tube 104, and under the limiting action of the limiting mechanism, the stability of the storage of the second connecting tube 104 is maintained, thereby avoiding the second connecting tube 104 from being entangled and damaged due to human winding, thereby further improving the convenience of use and the safety of storage of the second connecting tube 104, and ensuring the normal use performance of the external dental cleaning machine.

[0031] Example 2

[0032] See also Figure 3 and Figure 5, this embodiment further explains Example 1, the limiting mechanism in the figure includes a fixing plate 401 fixedly connected to the inner wall of the storage frame 201, a limiting rod 402 is slidably connected to the fixing plate 401, one end of the limiting rod 402 close to the storage tube 202 is fixedly connected to the limiting plate 403, a limiting ring 404 is fixedly connected to the side wall of the storage tube 202, a plurality of limiting holes 405 are provided on the side wall of the limiting ring 404, each limiting hole 405 is matched with the limiting plate 403, and a slope 406 is provided on one side of the limiting plate 403, and the slope 406 slides on the side wall of each limiting hole 405;

[0033] It should be noted here that when the second connecting tube 104 is pulled, the limiting ring 404 on the receiving tube 202 will be synchronously driven to rotate. During the rotation of the limiting ring 404, when the limiting plate 403 abuts against the limiting hole 405, the limiting plate 403 will be pushed to move away from the limiting ring 404 under the interaction force of the inclined surface 406 and the guiding action of the limiting rod 402. Therefore, during the process of the second connecting tube 104 being pulled outward, the limiting plate 403 will not interfere with the pulling of the second connecting tube 104, thereby ensuring the normal pulling out of the second connecting tube 104. After the second connecting tube 104 is completely pulled out, the limiting plate 403 will be driven to enter the limiting hole 405 under the elastic force of the first spring 408, thereby realizing the limiting of the receiving tube 202 under the limiting action of the limiting plate 403, further limiting the pulled out second connecting tube 104, and ensuring the stability of the second connecting tube 104 during use.

[0034] It is worth noting that when the second connecting tube 104 is in use, it is necessary to completely pull it out from the receiving tube 202 to avoid poor water delivery caused by the entanglement of the second connecting tube 104 .

[0035] See also Figure 3 and Figure 5 The other end of the limiting rod 402 shown in the figure penetrates the storage frame 201 and is fixedly connected to a pull plate 407. The limiting rod 402 is located on the side wall inside the storage frame 201 and is sleeved with a first spring 408. The two ends of the first spring 408 are respectively connected to the inner wall of the storage frame 201 and the fixed plate 401;

[0036] It should be noted here that: by providing the pulling plate 407 , it is easy to drive the limiting plate 403 at one end of the limiting rod 402 to disengage from the limiting hole 405 , thereby releasing the limiting of the storage tube 202 .

[0037] Example 3

[0038] See also Figure 4This embodiment is a further explanation of other embodiments. The storage frame 201 shown in the figure is provided with a back-force assembly for performing back-force on the second connecting tube 104. The back-force assembly includes a back-force tube 501 fixedly connected to the inner wall of the storage frame 201. The back-force tube 501 is concentrically arranged with the storage tube 202. A spiral spring sheet 502 is arranged in the back-force tube 501. The two ends of the spiral spring sheet 502 are respectively connected with the storage tube 202 and the back-force tube 501.

[0039] It should be noted here that: when the second connecting tube 104 is pulled, the storage tube 202 will be driven to rotate synchronously, thereby further deforming the spiral spring sheet 502 and generating elastic force. When the second connecting tube 104 needs to be stored, the limit on the storage tube 202 is released, and the storage tube 202 will be driven to rotate under the elastic force of the spiral spring sheet 502, thereby further driving the second connecting tube 104 to be wound around the side wall of the storage tube 202, thereby realizing automatic storage of the second connecting tube 104.

[0040] It is worth noting that: in the process of the rebound component driving the second connecting tube 104 to be automatically stored, for safety reasons, the operator is required to keep pulling the second connecting tube 104 and slowly loosen the second connecting tube 104 so that the second connecting tube 104 is evenly wound around the side wall of the storage tube 202.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
