Abstract

The utility model provides a novel electric tooth-brush, which can clean teeth from three faces simultaneously. The both sides of the teeth are cleaned automatically by two independently rotating brush bars with the same strength along the teeth slit, dirt on the front faces of the different angles of the teeth and dirt deep at dental caries are removed completely by four rotating bristle brooms which are rotated in two different directions. Two sheathings make a cleaning space formed at the cleaning point, and thus the teeth are protected in a more sanitary and more effective way.

Description

Electric toothbrush

What the present invention relates to is a kind of improved electric toothbrush, employed toothbrush and electric toothbrush in our daily life, to do on tooth in use that the right side, a left side, positive three faces are ceaselessly moving to be done, by it is when front tooth is inboard up and down before brush, toothpaste foam splashes, often inconvenience is scrubbed, and the tooth inboard has deposited a lot of tartar year in and year out.

The invention provides and a kind ofly simultaneously tooth three faces are done the modified electric toothbrush of effectively cleaning with water.Two brush posts and four by one's own efforts the hair broom of rotation form scrub the space, can much cleaner, more effectively finish the overall process of brushing teeth.

Task of the present invention is to finish as follows: electric toothbrush head is by two brush posts that can rotate by one's own efforts and a middle brush of being made up of the hair broom of four independent rotations.Two brush posts are equipped with the semicircle type sheath respectively.Two brush posts are positioned at two of tooth, motor provides power, by gear drive, the brush post is sideway swivel in toothbrush all the time on two, while is under the active force of gear except that rotation, two brush posts inwardly lean on naturally, and when having guaranteed brush food tooth and front tooth like this, two brush posts the tooth rotation with certain mechanical compliance all the time.Four hair brooms of middle brush also under the transmission of gear, rotate with two different directions, are responsible for the tooth front is cleaned with water.Because two brush posts rotate along tooth in the tooth both sides respectively, in the hair broom that brushes rotate to two different directions, thereby dental surface and dirt in each slit are thoroughly brushed.

Below in conjunction with accompanying drawing invention is described in further detail.

Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the present invention.

Fig. 2 is the concrete part section right view of Fig. 1 electric toothbrush.

Fig. 3 is the profile of Fig. 2 along the A-A line.

According to Fig. 1, bonnet (1) and precursor (2) fuse with a chain for binding criminals line.There are two batteries (3) to make two batteries (3) form series connection by connecting plate (43) (making) with elastic copper sheet in bonnet (1) lining, two batteries (3) are placed on fixed mount (4) lining, fixed mount (4) top has two boss (5) to be stuck in precursor (2) groove (6) to locate, there are (12) electrodes of positive electrode (7) (making) and motor to be connected before fixed mount (4) head with elastic copper sheet, the negative pole of one of negative electrode (8) (making with elastic copper sheet) and battery (3) is connected, and the other end upwards promotes and the connection of motor (12) electrode by switch (9).Motor (12) is to be placed in the cavity of precursor (2).The small boss (11) that the motor front portion has a little groove (10) to be stuck in precursor (2) locates to make it fixing.The travelling gear (13) of motor (12) and gear (15) interlock on the power transmission shaft (14).Nylon jacket (16) nylon jacket (17) and precursor (2) cast solid.Boss (21) on the brush holder (19) is stuck in precursor (2) upper groove (20) lining, and precursor (2) and brush holder (19) row is integral.Power transmission shaft (14) is placed in the cavity that brush holder (19) and precursor (2) form, and block (18) blocks that power transmission shaft (14) makes it can not play, and block (18) is to be fixed on precursor (2) with a chain for binding criminals nail (45).With reference to Fig. 1, Fig. 2, power transmission shaft (14) head is done half garden shape, the cooperation that travelling gear (22) closes.Worm screw (23) and gear (24) also have gear (25) cast solid, there is a through hole at the center, a chain for binding criminals nail axle (26) head has a chain for binding criminals line (making with stainless steel) to pass the hole of fixed stop (27) and the axis hole of snail worm screw (23) gear (24) gear (25) is fixed on brush holder (19), whole rotatable, gear (25) and gear (22) interlock, there is axis hole at gear (28) center, fix by axis hole and brush holder (19) that a chain for binding criminals nail axle (29) (making with stainless steel) head has a chain for binding criminals line to pass block (46) and gear (28), gear (28) turns again and (24) interlock.With reference to Fig. 3, gear (24) and gear (28) again respectively with relative two gears (30) interlock, the gear of these two symmetries (30) again respectively with gear (32) interlock of two symmetries.Gear (32) and brush post (34) cast solid.There are being 4 row's hair broom (35) rows to be planted on the brush post (34) on the brush post (34), there is an axis hole at brush post (34) center, there is a chain for binding criminals line (making) to pass (37) one of sheaths with a chain for binding criminals nail axle (36) head with stainless steel, fix passing brush axis hole, post (34) center and other end, brush post (34) is rotatable.Two risers (38) are arranged on the sheath (37), it is concentric that riser (38) has axis hole and gear (30) axis hole, there is a chain for binding criminals line (making) to pass the previous axis hole of riser (38) by a chain for binding criminals nail axle (39) head, at the axis hole of cavity that passes brush holder (19) and gear (30) with stainless steel; A back axis hole of riser (38) is fixed on the brush holder (19).The hair broom (40) of four independent rotations respectively with four worm gears (41) cast solid, four holes passing on the brush board (31) are passed through a mao broom (40).The previous interlock of worm screw (23) and four worm gears (41), previous worm gear again with next worm gear interlock, one of interlock of such four worm gears will be rotated with two kinds of rightabouts.Protecgulum (42) both sides have boss (33) to be stuck in two upper grooves (44) on the precursor (19) respectively, thereby block four worm gears (41).

When making negative pole, connects pull switch (9), motor (12) rotation, by gear (13) power is passed to gear (15), passing to gear (22) by power transmission shaft (14), gear (22) is travelling gear (25) and gear (24), worm screw (23) again, and worm screw (23) makes four hair brooms rotate with two kinds of rightabouts.With reference to Fig. 3, gear (24) is respectively for moving gear (28) and two symmetrical gears (30), gear (30) moving relative two gears (32) of generation are rotated counterclockwise left side brush post (34), and the right brush post is along ground pin rotation.Because riser (38) axis hole of two sheaths (35) is concentric with two symmetrical gears (30) axis hole respectively, two sheaths (35) can be done 90 ° of rotations, two sheaths (35) are inwardly rotated, contemporary moving two brush post rotations.Like this no matter two brush posts can keep giving cleaning with water of certain dynamics to tooth all the time automatically when brush food tooth, front tooth, as long as electric toothbrush is placed on the tooth, two sheaths (35) and brush board (31) form one and scrub the space, and tooth is effectively scrubbed.Bonnet (1), precursor (2), brush holder (19), switch (9), protecgulum (42) can be made of plastic.Gear can be made with nylon material.
