Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment as necessary without making a contribution thereto after reading the present specification, but all are protected by patent laws within the scope of the claims of the present invention.

The present embodiment relates to a visual dental scaler, as shown in fig. 1, 2 and 4, comprising: a body 1, a tip 2, a transducer 7 and a camera 3. The mirror surface 4 of camera 3 is the slant setting, has the contained angle between camera 3 and the work point 2, specifically is: the axis of the tip 5 of the tip 2 is at an angle of 25-35 degrees to the normal to the mirror surface 4 of the camera 3. Such angle setting for when cleaning tooth, the angle that camera 3 shot is better, and when cleaning the tooth of the inside most, camera 3 can shoot the tooth and survey in, and is cleaner with the tooth more easily.

In order to make the imaging angle clearer when the working tip 2 works, the distance between the tip 5 of the working tip 2 and the mirror surface 4 is 10-15 mm.

Preferably, as shown in fig. 2, the tip 5 of the tip 2 is bent toward the imaging position of the camera 3. The tip 5 of the working tip 2 is easy to form a right angle with the teeth due to the arrangement, the operation is more convenient when the teeth are cleaned, dirt on the teeth can be more conveniently ground, the energy transfer of the transducer 7 can be more conveniently utilized, and better experience is brought to customers.

As shown in fig. 3, the tip 2 is fixedly mounted on the upper end of the transducer 7 by means of a bolt 10, and the tip 2 can be replaced by rotating this nut 10.

In order to keep the direction of the working tip 2 consistent with that of the camera 3 all the time, a limiting structure is arranged at the assembly position of the working tip 2 and the transducer 7.

In a specific embodiment, as shown in fig. 6, the limiting structure includes: a third tangent plane 11 arranged on the side surface of the cylinder at the lower end of the working tip 2; and a fourth section 12 corresponding to the third section 11 and provided on the inner wall of the sleeve at the upper end of the transducer 7. The installation direction of the working tip 2 is limited, namely the third tangent plane 11 is abutted to the fourth tangent plane 12, so that the working tip 2 cannot rotate relative to the transducer 7, and the direction of the working tip 2 is always consistent with that of the camera 3 after the working tip 2 is replaced.

In another embodiment, as shown in fig. 7, the position limiting structure includes: a limiting bulge 13 arranged at the lower end of the working tip 2; and a limit groove 14 provided at the upper end of the transducer 7 corresponding to the limit projection 13. The installation direction of the work tip 2 is limited, namely the limiting protrusion 13 is inserted into the limiting groove 14, so that the work tip 2 cannot rotate relative to the transducer 7, and the direction of the work tip 2 is always consistent with that of the camera 3 after the work tip 2 is replaced. Specifically, the limiting protrusion 13 is triangular prism-shaped, and a pyramid faces downward.

The conventional dental scaler can only replace the tip 2, but the housing beside the tip 2 also has a sanitary problem. Thus, in this embodiment, as shown in fig. 3, the upper portion of the body 1 is detachably assembled with a head housing 6, the head housing 6 is sleeved outside the working tip 2 and the camera 3, and a space for the working tip 2 and the camera 3 to extend out is correspondingly opened on the head housing 6. The head shell 6 can be replaced besides the traditional replacement of the work tip 2, and the multi-user operation is more sanitary. And after the head shell 6 is covered, the locking bolt 10 of the working tip 2 can be covered, the appearance is more beautiful, and meanwhile, the visual tooth cleaning instrument is safer and more sanitary when extending into the oral cavity. It should be noted that the connection mode between the head housing 6 and the body 1 is not limited, and may be a threaded connection, a snap connection, or other detachable connections.

As shown in fig. 5, a waterproof ring 8 is sleeved between the head casing 6 and the body 1, so that the waterproof performance of the visual tooth cleaning instrument is improved.

As a further important improvement, as shown in fig. 5, the side of the cylinder at the widest point of the transducer 7 is provided with a first cut 9; the inner wall of the transducer housing 15 is provided with a second cut surface (not shown) corresponding to the first cut surface 9. By providing the first and second cut surfaces 9, 9 abut against each other, so that the transducer 7 cannot be rotated when the tip 2 is replaced.

The working principle of the utility model is roughly as follows: the mirror surface 4 of camera 3 is the slant setting, has the contained angle between camera 3 and the work point 2, specifically is: the axis of the tip 5 of the tip 2 is at an angle of 25-35 degrees to the normal to the mirror surface 4 of the camera 3. Such angle setting for when cleaning tooth, the angle that camera 3 shot is better, and when cleaning the tooth of the inside most, camera 3 can shoot the tooth and survey in, and is cleaner with the tooth more easily.

The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention should be covered by the claims of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
