Abstract

The utility model discloses a tooth cleaner, which is composed of a tooth head 1, a tooth head shaft 2, a cleaner head 3, a cleaner body 4, a switch 5, a spring 6, and a micromotor 7, wherein the top part of the cleaner head 3 is provided with a hole. A hole diameter and the tooth head shaft 2 which is penetrated through the hole diameter are formed into a sliding fit. The tooth head 1 is fixed on the tooth head shaft 2. The lower end of the tooth head shaft 2 is penetrated in the spring 6. The other end of the spring 6 is sheathed on the micromotor 7. The micromotor 7 is respectively connected with the switch 5 and a battery 9 through a conducting wire 8. While in use, the rotation and the stop of the micromotor 7 can be realized by the switch 5. The kinetic energy of the micromotor 7 is transferred to the tooth head 1 by the spring 6, thereby, the tooth head 1 is caused to rotate in high speed with the micromotor 7. The friction force generated by the rotation of the tooth head 1 can rapidly clean dirt on teeth.

Description

Dental scaler

Technical field this utility model relates to a kind of utensil of cleaning teeth, and especially the micro machine motor drives the dental scaler that tooth is cleaned in the rotation of tooth head height speed.

It mainly is that dentistry to hospital is carried out that the present people of background technology clean one's teeth, not only expensive time-consuming, also causes cross infection because of the shared kit of many people sometimes.Some home-use clear tooth products had appearred in recent years on the market, people can buy back home and oneself clean one's teeth, but these products are made up of water preparation or powder mostly, though certain effect that cleans one's teeth is arranged, but use cumbersome, and will use continuously and for several times just can see positive effect, in the face of old dirt for many years is on duty mutually with the dental calculus effect.Recently domestic have producer to release home-use mechanical type dental scaler, but because of head is too big, not easy to clean near lingual surface tartar on one side, quite clumsy even the toothwash tooth outside also seems, open so be difficult to promote.

Utility model content the technical problems to be solved in the utility model provides a kind of effective, easy to use family wear apparatus type dental scaler, and this dental scaler can clean each face of each tooth, uses very convenient.For solving the problems of the technologies described above, the technical solution of the utility model is that the power with micro machine is transferred on the tooth head as rotating shaft with spring, after can moving to the main body middle part to the micro machine motor backward like this, head section can be done very for a short time and can not lower the speed and the moment of the rotation of tooth head.The profile of dental scaler is done streamlining, and head is less, and the fuselage main body is bigger, so that parts such as micro machine motor and cell switch can be loaded in inside, the junction natural torsion of head and main body is angled, uses more convenient.The shell of head and main body ABS injection molded, smooth surface is attractive in appearance, the inner various parts down of installing.One hole is arranged at the top of head, be slidingly matched with the tooth head shaft that passes wherein, the tooth head shaft upper end cooperates with the tooth head, the lower end connects spring, the other end of spring is enclosed within the rotating shaft of micro machine motor, the level height of micro machine rotating shaft is a little less than tooth head shaft core end, and is in together in the perpendicular with the axle core.The soft durometer of spring should be rotated freely with micro machine and is as the criterion.The both positive and negative polarity of micro machine is connected with the battery spring of switch by lead, passes through the start and stop of on-off control motor during use.

Description of drawings is described in further detail this utility model below in conjunction with the drawings and specific embodiments

Fig. 1 is the embodiment outline drawing of this utility model dental scaler

Fig. 2 is this utility model dental scaler embodiment cutaway view

The specific embodiment as depicted in figs. 1 and 2 dental scaler by tooth head 1, tooth head shaft 2, head 3, fuselage 4, switch 5, spring 6, micro machine motor 7 is formed.Tooth head 1 is fixed on the tooth head shaft 2, the diameter of axle is consistent with tooth head 1 aperture, screw thread is carved with on the surface, be complementary with tooth head endoporus screw, during use tooth head 1 rotated counter clockwise and be installed on the tooth head shaft 2, rotate to counter-clockwise aspect and the direction of rotation of tooth head shaft 2 is consistent with the rotation of micro machine motor 7, its objective is to prevent that tooth head 1 from being got rid of in rotation.The base of tooth head shaft 2 is garden stage bodies, and the diameter on last base is than tooth head 1 slightly larger in diameter, and the diameter of bottom is the same with head 3 top diameters.Tooth head shaft 2 upper ends are through in the hole of tooth head 1, the lower end is through in the spring 6, the other end of spring 6 is enclosed within the rotating shaft of micro machine 7, and the both positive and negative polarity of micro machine 7 is connected with switch 5 with battery 9 by lead 8, realizes the start and stop of micro machine 7 during use by switch 5.When opening switch 5, the electric energy of battery 9 is given to micro machine 7, and the kinetic energy of micro machine 7 is passed to tooth head shaft 2 by spring 6 and driven 1 rotation of tooth head.Owing to make drive shaft with spring 6, the kinetic energy of its transmission can be to any direction, thus the angle of 4 of the main bodys of head 3 and fuselage is made unspecified angle, and simultaneously with micro machine 7 to the rear portion of fuselage main body dislocation, can do head 3 very for a short time like this, use also more convenient.

Claims (3)

1, a kind of dental scaler, by tooth head (1), tooth head shaft (2), head (3), switch (5), micro machine (7) in fuselage (4) and the fuselage, spring (6) is formed, this tooth head (1) can take off for flexibly connecting with tooth head shaft (2), it is characterized in that: described tooth head (1) is for conical, in an aperture is arranged, hole wall is carved with screw thread, pore size and tooth head shaft (2) match, tooth head shaft (2) is the parts of a T font, T word top is the chassis of tooth head shaft, and its diameter and head (3) are suitable, and the bottom of T word is the cylinder of tooth head, diameter and tooth head (1) aperture match, on be carved with screw thread.
