Description

Rotary tooth-brush

The utility model belongs to the Tooth-brush structure technical field

Current toothbrushes all is to be connected on the toothbrush handles by manually holding toothbrush handles by bristles to move up and down in the oral cavity and reach the purpose of oral cavity cleaning usually, also has a kind of travel toothbrush, toothbrush handles is done curl, in the handle of a special use of precession, still come oral cavity cleaning by artificial mobile toothbrush, the time spent can not screw in head toothbrushes and make it the yet health that is easy to carry in the handle.But; type of toothbrush always is difficult to avoid because manually-operated direction randomness at present; causing brushes teeth is difficult to meet science operation requirement; a lot of people get used to laterally brushing teeth also because people's hand-power weight impermanence; produce the phenomenon of injury gum through regular meeting; both do not reached the purpose of cleaning teeth; also damage the oral cavity easily; even because people's the toothbrush handles of holding is leaned on moving with strength of swinging arm; also impel toothbrushing person to be difficult to keep correct body position; adhere to that the regular hour brushes teeth, always be tending towards dealing with and get over.

The purpose of this utility model provides a kind of toothbrushing person that can guarantee to brush teeth with scientific method in order to overcome existing toothbrush above shortcomings part just, thoroughly change the custom that people laterally brush teeth, the Anti-dental injury gum, a kind of rotary tooth-brush that moves and brush teeth by swinging arm without toothbrushing person.

The purpose of this utility model is achieved by the following technical solution:

Head toothbrushes is a cylinder hairbrush, and bristles is distributed in the cylinder periphery, and bristles is the undulate shape vertically.Head toothbrushes is that the top is little, the truncated cone-shaped hairbrush that the bottom is big; This toothbrush is provided with the whirligig of being made up of handle, casing, transmission system, guide rod elevating arc, by toothbrush handles being inserted in the guide hole of guide rod elevating arc, driving the toothbrush handles axial rotation by transmission system, and then makes also axial rotation of head toothbrushes.Transmission system is made up of convex gear, driving wheel, left driven elevating arc, right driven elevating arc, shifting axle, the cross sectional shape and the guide hole cross sectional shape of toothbrush handles and the guide rod elevating arc guide hole section of connecting are rectangle, be provided with an alignment pin in guide rod elevating arc stage casing, lean cooperation mutually with the fixedly card that is located at the casing sleeve lining; Being outside equipped with one at head toothbrushes, be fixed in can be along the half-open sleeve of toothbrush handles axial rotation on the toothbrush handles.

Further set forth the utility model content below in conjunction with Figure of description and embodiment:

Fig. 1 looks cutaway view for the utility model master,

Fig. 2 is the vertical view cutaway drawing of Fig. 1,

Fig. 3 is the A-A cutaway view of Fig. 1,

Fig. 4 is the B-B cutaway view of Fig. 1.

Head toothbrushes 1 is made a column type, and bristles evenly is connected on the cylinder vertically, and bristles is the undulate shape vertically.Toothbrush handles 2 fuses with head toothbrushes 1 and makes, and toothbrush handles 2 is a rectangle with the cross sectional shape of guide hole 18 sections of connecting, and such as square, also is provided with boss rank 3 in the stage casing of toothbrush handles 2, is specifically designed to the fixedly insertion depth of toothbrush handles 2.Outside head toothbrushes, make a half-open sleeve 20, but sleeve 20 is enclosed within on the toothbrush handles 2 and axial rotation by lasso 21.Whole whirligig is made up of handle 15, casing 13, interior deckle board 12 and a transmission system.Transmission system is made up of a convex gear 11, driving gear 10, left driven elevating arc 9, right driven elevating arc 7 and shifting axle 8 and guide rod elevating arc 6.Convex gear 11 is fixed on the interior deckle board 12 for protruding axle 16, bottom integral body is connected with the axial rotation body of plate machine 17, blocking the spring 14 of moving is enclosed within on the protruding axle 16, its section of stretching out is stuck in the plate machine 17, when plate machine 17 during along protruding axle 16 axial rotation, the tooth portion of convex gear 11 also begins along protruding axle 16 axial rotation, driving gear 10 is the gear shafts that fused by a gear wheel and pinion, its axis also is fixed on casing 13 inwalls separately, this pinion tooth portion direct and convex gear 11 meshes, the gear wheel of driving gear 10 respectively with a left side, right driven elevating arc 7,9 engagements, and a left side, right driven elevating arc meshes with guide rod elevating arc 6 respectively again, inwall at casing sleeve 19 is provided with a fixing card 4, and the guide rod section that is specifically designed to location guide elevating arc 6 makes it not to be subjected to displacement; Card 4 is corresponding with fixing, also be provided with an alignment pin 5 on the guide rod stage casing of guide rod elevating arc 6, play the purpose that leans cooperation with fixing card 4 mutually, whole guide rod elevating arc 6 dextrad in the axial direction is subjected to the location of left and right driven elevating arc 7,9, left-hand is subjected to the location of fixing card 4, makes it fixing.Shifting axle 8 is axis of the left and right driven elevating arc 7,9 in location, thereby the left side that it can be by staff by with the right side by determining left driven elevating arc 9 or right driven elevating arc 7 and 6 engagements of guide rod elevating arc, deckle board 12 extended with casing 13 1 ends in shifting axle 8 passed, and presses axle head by people's hand inner transmission system is meshed on request.

When people's finger is pulled plate machine 17 on the convex gear 11 along camshaft 16 axial rotation, the tooth portion of convex gear 11 drives the pinion rotation on the driving gear 10, and then order about its gear wheel and also rotate, gear wheel is meshed with left and right driven elevating arc 7,9, when shifting axle 8 is pressed to the right, right driven elevating arc 7 and 6 engagements of guide rod elevating arc, by when the left side, driven elevating arc 9 in a left side and 6 engagements of guide rod elevating arc, thereby the guide rod that makes guide rod elevating arc 6 can be left and right direction rotation, also just can make the toothbrush handles 2 of inserting guide hole can be left and right direction rotation.Convex gear 11 has a sliding tray by the return of spring 14 because the axis of driving gear 10 is fixed on the interior deckle board 12, so can not cause driving gear 10 counter-rotatings.

When people brush teeth, toothbrush handles 2 is inserted in the guide rod guide hole 18 partly of guide rod elevating arc 6 in the whirligig.When the user needs right rotation head toothbrushes 1 with the peak with heading portion right side of shifting axle 8 by flat, the moving plate machine 17 of plate, head toothbrushes 1 just can axially rotate freely then, along vertical cleaning teeth space of tooth, when needing, shifting axle 8 is pressed on a left side, can oppositely scrub tooth again.When brushing teeth, rotate at any time and adjust the sleeve position, so that bristles does not injure cheek face, endognath face and tongue.

The utility model has and can adopt scientific method to brush teeth compared with prior art, brush The even Anti-dental injury gum of tooth dynamics, be beneficial to toothbrushing person with the correct method long period brush teeth obviously Advantage thoroughly changes the bad habit that people laterally brush teeth.
