Abstract
The utility model discloses a hand driven rotary toothbrush which is mainly characterized in that by using lever principle and the effect of compression spring and by the move that the friction lever of manual control drives a roller to move, the straight reciprocating motion of the toothbrush in a mouth cavity can be changed into the reciprocating-rotating motion of a toothbrush head in the mouth cavity; thus, the purpose of tooth cleaning can be achieved. The utility model has the advantages of simple structure, reasonable design, convenient operation, low cost; besides, components and parts are all have changeabilities.
Description
The utility model is a kind of manual rotary toothbrush.
At present, people's toothbrush of being used to clean the teeth comprises that mainly an elongate handgrip is loaded with the toothbrush body of bristle and for bristle for toothbrushing at its front end.Abroad the someone has invented the adjustable toothbrush that can regulate bristle lengths, its toughness and rigid can according to user's needs when brushing teeth regulated at will to needed in various degree to adapt to the situation of each position of tooth and tooth shape; Also has a kind of electric toothbrush because its complex structure and can not be general.Above toothbrush generally be by toothbrush at intraoral rectilinear motion, the surface and the slit of tooth are washed away repeatedly, remove behind the dirt and food debris to reach the purpose in cleaning teeth, oral cavity.Because the out-of-flatness of dental surface, and majority's teeth arrangement is irregular, the gap size of its tooth differs, though general toothbrush also can move up and down in the oral cavity, but still very big groups of people's faulty toothbrushing arranged, can not all reject the residue of teeth crevice, some shelter is not really brushed.
The purpose of this utility model is that design provides a kind of manual rotary toothbrush, can more correctly clean the teeth the user.
The toothbrush of this manual rotary has utilized lever principle, but makes original toothbrush become the rotatable motion of linear reciprocation in intraoral straight reciprocating motion.Toothbrush is made up of band bristle part and handle two parts, utilizes a swingle that both are linked together.One end of swingle is fixed on the head toothbrushes of band bristle, and the other end inserts in the interior mobilizable cone rubber cylinder of toothbrush handle.Swingle must and cone rubber cylinder tight fit get loose preventing.Utilize bolt and nut relative fixed friction lever on toothbrush handle, as the fulcrum of friction lever, friction lever can swing up and down screw rod more freely under this fulcrum supports again.One end of friction lever contacts with rubber cylinder, and its contact site is processed with serration, to increase frictional force.The other end of friction lever is near one on toothbrush handle tail end compression spring, pressuring spring at any time when manual control.
This manual rotary toothbrush adopts the design philosophy of movable teeth brush.By the effect of staff and secondary spring, the oscillating motion of friction lever is converted into rotatablely moving of head toothbrushes, reach the purpose that correctly cleans the teeth.It is simple and reasonable for structure.The parts of toothbrush all have versatility, commutativity, therefore can change consumable accessory at any time, and are with low cost, use and conveniently, generally suit per capita to use.
Accompanying drawing has been represented a specific embodiment of the present utility model.
Fig. 1 is the front view of manual rotary toothbrush
Fig. 2 is the A-A profile of manual rotary toothbrush.
As shown in drawings, this manual rotary toothbrush is divided into head toothbrushes (1) and handle (2) two parts.Head toothbrushes (1) is the garden form, directly contacts gum and oral mucosa when its bristle rolls in the oral cavity, selects thin stronger bristle.Toothbrush handle (2) adopts plastic injection-moulded shaping.Utilize a swingle (6) to connect head toothbrushes (1) and toothbrush handle (2), the available stainless steel tube of swingle (6) or other harder materials are made.These swingle (6) one ends insert in the prefabricated hole of head toothbrushes (1), and the other end inserts in the interior cone rubber cylinder (8) of handle (2), and pad upper gasket (7).Rubber cylinder (8) can be free movable in handle (2).Swingle (6) should with rubber cylinder (8) tight fit.The tail end of handle (2) utilizes a screw (5) to fix a compression spring (4), and handle (2) middle-end is utilized a screw rod (10) and nut (a 9) friction lever of relative fixed (3).Friction lever (3) one ends are processed with serration and tightly are close to rubber cylinder (8), to avoid the sliding friction between friction lever (3) and the rubber cylinder (8), guarantee the reliable of brush (1), roll flexibly.The other end of friction lever (3) is near the compression spring (4) of toothbrush tail end.Utilize standing screw (10) to make the fulcrum of friction lever (3), when brushing teeth head toothbrushes stretched into and control the end that dynamic friction bar (3) is close to spring (4) in the oral cavity gently, can utilize the effect of lever principle and compression spring (4) that the other end of friction lever is swung up and down, thereby drive the rotation that the friction tight swingle of rubber cylinder (8) (6) drives head toothbrushes (1), control its head toothbrushes of dynamic friction bar repeatedly and just rotate repeatedly, can reach the purpose that cleans the teeth.
Claims (1)
- A kind of manual rotating toothbrush of forming by head toothbrushes, toothbrush handle, a rubber cylinder free to rotate is characterized in that packing in toothbrush handle, fix a compression spring at the handle tail end, handle middle-end relative fixed one friction lever, as the fulcrum of friction lever, friction lever one end is processed with serration to its standing screw, near rubber cylinder again, the other end is close to the compression spring of handle tail end, and head toothbrushes links to each other with a swingle with toothbrush handle.Its method of attachment is that an end of swingle is pressed in the head toothbrushes, and the other end inserts in the interior mobilizable rubber cylinder of toothbrush handle.
