Description

Three-purpose gun barrel for dental cleaning Technical Field The utility model relates to the technical field of dental instruments, in particular to a three-purpose gun barrel for dental cleaning. Background In dental oral treatment, the three-purpose gun plays a critical role as a key cleaning tool. It has the function of spraying water and/or air to the oral cavity of the patient to meet the requirements of different treatment stages. In the prior art, the barrel of the three-purpose gun is bent into a specific angle when leaving the factory, and the three-purpose gun cannot be elastically restored. The gun barrel design with fixed angle has a plurality of defects, and the specific steps are as follows: the difficulty in achieving more irrigation angles results in significant limitations in facing complex oral structures, rendering the oral cavity interior portions insufficiently irrigated. When coping with the oral conditions of different patients or the conditions of different oral positions of the same patient, the flushing angle cannot be flexibly adjusted to influence the flushing effect, so that different use requirements cannot be flexibly adapted. Therefore, how to solve the above-mentioned drawbacks of the prior art is a subject to be studied and solved by the present utility model. Disclosure of utility model The utility model aims to provide a three-purpose gun barrel for dental cleaning. In order to achieve the above purpose, the utility model adopts the following technical scheme: A three-purpose gun barrel for dental cleaning comprises a water pipe, a support pipe and an air pipe which are sleeved in sequence from inside to outside; the water pipe is provided with a water delivery channel; an air channel is arranged between the outer wall of the supporting tube and the inner wall of the air tube; the water pipe is provided with a first connecting section, a first bending section and a second connecting section which are sequentially connected; The support tube is provided with a third connecting section, a second bending section and a fourth connecting section which are sequentially connected; The air pipe is provided with a fifth connecting section, a third bending section and a sixth connecting section which are sequentially connected; The first bending section, the second bending section and the third bending section are arranged correspondingly and can be bent. The first connecting section, the third connecting section and the fifth connecting section are correspondingly arranged. The second connecting section, the fourth connecting section and the sixth connecting section are correspondingly arranged. It should be noted that, the water pipe and the air pipe are the conventional structure of the three-purpose gun barrel, the water delivery channel and the air channel are the conventional design of the three-purpose gun barrel, and the working principle of the three-purpose gun barrel is not adjusted in the application. The sleeve is arranged in a conventional way, the support is also arranged in a conventional way, the support of the support tube can refer to the prior art when the sleeve is arranged, for example, a rubber ring which does not influence the air flow passing through is arranged between the support tube and the air tube, or the surface of the support tube is provided with a convex structure. The first bending section, the second bending section and the third bending section are correspondingly arranged. The second bending section and the third bending section are arranged to bend the first bending section conveniently. In the scheme, the first bending section, the second bending section and the third bending section can be bent, and the water pipe is used for illustration, and when the novel oral cavity washing machine is used, an included angle is formed between the first connecting section and the second connecting section by bending the first bending section, the second connecting section faces different areas in an oral cavity conveniently, the position of the second connecting section is flexibly adjusted to realize comprehensive washing of the different areas in the oral cavity, the washing effect is improved, the novel oral cavity washing machine is suitable for complex environments in the oral cavity, and the novel oral cavity washing machine is flexibly applicable to different patients. The support tube can fix and protect the water pipe, so that the air channel is formed according to a preset design, and the strength of the three-purpose gun barrel can be improved, thereby prolonging the service life of the three-purpose gun barrel. The water delivery channel is exemplified by a first connecting section, a first bending section and a second connecting section. For example, the present application does not emphasize whether the first connecting section and the second connecting section are bendable, but not limit the bendable arrangement. In general, the whole wat
