This utility model is achieved through the following technical solutions its practical novel purpose.

A kind of dental floss machine of this utility model design, its structure comprises handle, dental floss holder fixture, reciprocator and driving device, the dental floss holder fixture is installed in the handle front end, and driving device is installed in the handle and is connected with the driving of dental floss holder fixture by reciprocator.Driving device can the back and forth evenly motion of the dental floss holder of drive installation on the dental floss holder fixture by reciprocator.Mode by electronic automatic driving need not manually-operated, and is easy to use, and dynamics is even, and speed-controllable system has been avoided the infringement to gingiva.

Described driving device comprises motor and power supply, and motor and power supply are installed in handle inside vertically, and motor is installed in the power supply front end.Compact conformation has reduced the volume of dental floss machine, is easy to carry.Motor is installed in the motor cover, adopts battery as power supply, is placed in the battery compartment, and battery compartment is installed in the afterbody of motor cover, and power supply is connected energising by the cathode metal sheet and gives motor with negative pole sheet metal and battery spring.

Described driving device comprises the driving wheel that is connected with the motor center axle, the drive rod that an end is connected with the dental floss holder fixture, and the drive rod other end is socketed on the driving wheel, and is provided with the oblique groove fit of positioning needle and driving wheel side.It is big to have overcome in the gear drive noise, defectives such as complex process.This kind of drive has advantages such as its parts are few, simple in structure, and failure problems is low.

Change dental floss holder for convenience, fixture comprises at least two lamellar bodies and the locking knob that is connected on drive rod one end, and locking knob cooperates with the external screw thread of lamellar body by female thread.

Handle is made of the cooperation of front and back housing, and procapsid is provided with the silica gel sheath, is convenient to change power supply and plays anti-skidding effect.The gauge tap of driving device can also be arranged on the procapsid, and is easy to operate, meets the human engineering principle.

With respect to prior art this utility model major advantage is to replace artificial mode with electronic mode, science calculate dynamics required when cleaning one's teeth, provide fixed power with motor, it is stressed more even that it is worked together, the Anti-dental injury gum, when the dental floss holder head vertically seesawed the cleaning teeth space, hands also can be done slight moving up and down, thereby makes cleaning more thorough.

It is exactly that the dental floss holder head can be changed at any time that this utility model also has big characteristics, even be not the handle that same people also can use the dental floss machine jointly, only need to change flossing head and gets final product clean hygiene.And can clamp the dental floss holder head of multiple standards specification, compatible very extensively, so long as common non-special dental floss holder head can tighten.Flossing head can have been bought everywhere.Solved the defective that to buy special-purpose flossing head when user is bought other dental floss machine.

Dental floss holder can be unloaded down from handle, and dental floss holder and dental floss handle can separately carry.Very convenient.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is further described.

As accompanying drawing 1, Fig. 2 and shown in Figure 3, give motor 4 power supplies by No. 7 batteries 10, battery 10 is placed in the battery compartment 2, and battery compartment 2 is installed in the afterbody of motor cover 1, and power supply is connected energising by cathode metal sheet 3 and gives motor 4 with negative pole sheet metal 8 and battery spring 9.

A silica gel sheath 13 is coated in procapsid 11 outsides, and a circular protrusions 21 is arranged on the silica gel sheath 13, and the inboard of circular protrusions 21 has a small column that exceeds to match with the small sircle hole 26 of procapsid 11.When the normal front end that the circular pillar of inboard is just depressed cathode metal sheet 3 during by circular protrusions 21 of finger touches the metal shell of motor 4 downwards, and the metal shell of motor is connected with the cathode contact of motor, circuit turn-on, and motor 4 is started working.When finger unclamped not according to circular protrusions 21, sheet metal 3 was upspring and is left the motor metal shell, and circuit disconnects, and motor 4 quits work.

One reciprocator is positioned at procapsid 11, comprises driving wheel 5, drive rod 6 and positioning needle 7.Driving wheel 5 is tight with on the central shaft of motor 4, and drive rod 6 from outer wrap on driving wheel 5, overlap with it, and leave some gaps.Cooperation with it in the driving wheel 5 intermediary oblique grooves 22 is inserted and be deep into to positioning needle 7 by the lateral aperture 23 of drive rod 6.When motor 4 rotated, it is moving that power drive driving wheel 5 is made circumference, and the active force of circular motion drives positioning needle 7 and makes the inclined linear shuttling movement.Positioning needle 7 is advanced to spur drive rod 6 and is done vertical straight reciprocating motion along straight line chute 25 together with what make the inclined linear shuttling movement.Dental floss holder 15 moves back and forth, shown in arrow among Fig. 4 and dotted line.This kind kind of drive has replaced common gear drive, and it is big to have overcome in the gear drive noise, defectives such as complex process.This kind of drive has advantages such as its parts are few, simple in structure, and failure problems is low.

" F " shape dental floss holder 15 inserts in two lamellar bodies 24 of drive rod 6 fronts as shown in Figure 5, two lamellar bodies 24 of the front of locking knob 14 locking drive rods 6, make it clamp dental floss holder 15, two lamellar bodies 24 of the front of locking knob 14 and drive rod have gradient and the internal and external threads 27 that is complementary respectively, and installation process as shown in Figure 5.Therefore dental floss holder 15 is fixed on the drive rod 6, so just drive flossing head seesaw when drive rod 6 is done vertical straight reciprocating motion, in Fig. 4, dotted portion is the low-end trim of whole motion parts.
