Abstract
The utility model provides a single motor driven interaxial clearance fit electric toothbrush. The electric toothbrush comprises a toothbrush holder inserted into a hollow columnar outer sleeve, wherein a spring is arranged inside the outer sleeve and is connected with the outer wall of the part, inserted into the outer sleeve, of the toothbrush holder in a sleeved manner; the bottom of the toothbrush holder is connected with the top of a hollow connecting rod; the bottom of the connecting rod comes into contact with the working surface of a cam inside the outer sleeve; the cam and the connecting rod are connected in the vertical direction in a sleeved manner and are arranged on a columnar rotating shaft inside the outer sleeve; besides, the inner walls of the cam and the outer walls of the rotating shaft are fixedly connected; the inner walls of the connecting rod are in clearance fit with the outer walls of the rotating shaft; the rotating shaft is axially connected with a motor shaft of a motor arranged inside the outer sleeve. Due to the adoption of the structure, the defects of tooth margin injury and traumatic periodontitis easily caused because the rotation direction of a brush cup is also vertical to a brush head substrate are overcome.
Description
Technical field
This utility model belongs to tooth medical treatment device technical field, is specifically related to the electric toothbrush of the motor-driven between centers matched in clearance of a kind of list.
Background technology
At the tooth using at present, use in medical treatment device, electric toothbrush has reduced the workload of manual brushes, and it adopts motor-driven mode to brush teeth and operates the more stable application more and more widely that effectively obtained, but the brush of electric toothbrush now cup is perpendicular to brush substrate, the direction of rotation of brush cup is also perpendicular to brush substrate, and the tooth edge easily causing damages and cause the defect of periodontitis with wound.
Summary of the invention
The purpose of this utility model provides the electric toothbrush of the motor-driven between centers matched in clearance of a kind of list, the brush rod that comprises the outer sleeve inside of inserting hollow columnar, outer sleeve inside is provided with spring, spring housing is connected on brush rod and inserts on outer sleeve outer wall partly, the bottom of brush rod is connected with the top of the connecting rod of hollow, the bottom of connecting rod contacts with the working surface of the cam of sleeve inner outside, and cam and connecting rod are all socketed in the vertical direction and outside on the rotating shaft of the column of sleeve inner, the inwall of cam is fixedly connected with the outer wall of rotating shaft in addition, and the inwall of connecting rod is with the outer wall phase matched in clearance of rotating shaft, and rotating shaft connects with the motor shaft phase axle that is arranged on the motor of outer sleeve inside.Such structure has avoided the direction of rotation of brush cup also perpendicular to brush substrate, the tooth edge damage easily causing and the defect that causes periodontitis with wound.
In order to overcome deficiency of the prior art, this utility model provides the solution of the electric toothbrush of the motor-driven between centers matched in clearance of a kind of list, specific as follows:
The electric toothbrush of the motor-driven between centers matched in clearance of a kind of list, the brush rod 1 that comprises handle shape, one of brush rod 1 is provided with bristles 2, the other end of brush rod 1 is inserted outer sleeve 3 inside of hollow columnar from top to bottom, outer sleeve inside is provided with spring 4, spring 4 is socketed in brush rod 1 and inserts on the outer wall of outer sleeve 3 parts, and one end of spring 4 is fixed on outer sleeve 3 inwalls, the other end of spring 4 is fixed on brush rod 1, the bottom of brush rod 1 is connected with the top of the connecting rod 5 of hollow, the bottom of connecting rod 5 contacts with the working surface of cam 6 in outer sleeve 3 inside, and cam 6 and connecting rod 5 are all socketed in the vertical direction and on the rotating shaft 7 of the column of outer sleeve 3 inside, the inwall of cam 6 is fixedly connected with the outer wall of rotating shaft 7 in addition, and the inwall of connecting rod 5 is with the outer wall phase matched in clearance of rotating shaft 7, and rotating shaft 7 connects with the motor shaft 9 phase axles that are arranged on the motor 8 of outer sleeve 3 inside.
The inwall of described connecting rod 5 is-0.005～0 with the fit tolerance scope of the outer wall phase matched in clearance of rotating shaft 7.
Application this utility model such scheme, by by the inwall of cam 6, the outer wall with rotating shaft 7 is fixedly connected, and the inwall of connecting rod 5 is with the outer wall phase matched in clearance of rotating shaft 7, and rotating shaft 7 connects with the motor shaft 9 phase axles that are arranged on the motor 8 of outer sleeve 3 inside.Can realize like this motor 8 rotates by rotating shaft 7 band moving cams 6 and connecting rod 5 when starting, so further cam 6 just can drive connecting rod 5 not only can rotate and can also realize reciprocal rectilinear motion, so just can really realize by a motor 8 rotation and the rectilinear motion of electric toothbrush.
Accompanying drawing explanation
Figure l is the internal structure schematic diagram of the electric toothbrush of the motor-driven between centers matched in clearance of this utility model list.
The specific embodiment
Below in conjunction with accompanying drawing, utility model content is described further:
Shown in Fig. 1, the electric toothbrush of single motor-driven between centers matched in clearance, the brush rod 1 that comprises handle shape, one of brush rod 1 is provided with bristles 2, the other end of brush rod 1 is inserted outer sleeve 3 inside of hollow columnar from top to bottom, outer sleeve inside is provided with spring 4, spring 4 is socketed in brush rod 1 and inserts on the outer wall of outer sleeve 3 parts, and one end of spring 4 is fixed on outer sleeve 3 inwalls, the other end of spring 4 is fixed on brush rod 1, the bottom of brush rod 1 is connected with the top of the connecting rod 5 of hollow, the bottom of connecting rod 5 contacts with the working surface of cam 6 in outer sleeve 3 inside, and cam 6 and connecting rod 5 are all socketed in the vertical direction and on the rotating shaft 7 of the column of outer sleeve 3 inside, the inwall of cam 6 is fixedly connected with the outer wall of rotating shaft 7 in addition, and the inwall of connecting rod 5 is with the outer wall phase matched in clearance of rotating shaft 7, and rotating shaft 7 connects with the motor shaft 9 phase axles that are arranged on the motor 8 of outer sleeve 3 inside.The inwall of described connecting rod 5 is-0.005～0 with the fit tolerance scope of the outer wall phase matched in clearance of rotating shaft 7, and integrated rotation and the synchronous linear motion under the working surface of cam 6 drives between connecting rod 5 and rotating shaft 7 both can easily have been processed and can better have been completed to such fit tolerance scope.
Operation principle of the present utility model is that motor 8 rotates by rotating shaft 7 band moving cams 6 and connecting rod 5 when starting, so further cam 6 just can drive connecting rod 5 not only can rotate can also realize reciprocal rectilinear motion under the elastic reaction of spring 4, so just can really realize by a motor 8 rotation and the rectilinear motion of electric toothbrush.
