Description

A kind of multi-function rotable toothbrush

Technical field

The utility model relates to a kind of toothbrush, in particular to a kind of multi-function rotable tooth that can simultaneously bi-directionally clean tooth Brush.

Background technique

Traditional manual toothbrush, which needs to act up and down, can just brush teeth, not easy to operate, and take time and effort；Electric toothbrush needs Want built-in or external power supply as power, and mechanism is complicated, price is relatively expensive.In view of the above-mentioned problems, ZL200420048500, The patents such as ZL200580020261, ZL201320646058 propose add new man-operated mechanism for toothbrush head rotation provide it is dynamic The technical solution of power, but this needs to add other operations while hand-held toothbrush, it is still not practical enough, especially for possible For unhandy children and old man.

Utility model content

In order to improve the above problem, the utility model is by providing a kind of multi-function rotating that can simultaneously bi-directionally clean tooth Dynamic toothbrush.

To achieve the above object, the utility model is using following design:

A kind of multi-function rotable toothbrush, structure include brush head, brush handle component, and brush head includes at least one cylinder rolling Brush, brush handle component include brush head rotation control assembly and hollow brush handle；Brush head rotates control assembly one end connection brush head, the other end Go deep into hollow brush handle, and is connected with the sliding of hollow brush handle；

The brush head rotation control assembly includes connecting rod, the rack gear for being embedded in hollow brush handle cavity inner wall, is engaged with rack Displacement gear, displacement gear position-limit mechanism, rotation gear；

Connecting rod one end connection brush head, the other end are fixedly connected with rotation gear；

Rotate gear basal plane perpendicular to length of connecting rod direction and simultaneously with displacement gear concurrent aces engaged transmission.

Brush head turns the linear motion between brush head, connecting rod and hollow brush handle in use, rotating control assembly by brush head It is changed to the rotation of brush head.

Further, the rotation gear can be ring gear or bevel gear, when rotating gear is ring gear, institute's rheme Moving gear is spur gear or bevel gear；When rotating gear is bevel gear, the displacement gear is bevel gear.By ring gear, The intersecting axle engaged transmission of rotation gear and displacement gear is realized in combination between the combination or bevel gear of spur gear.

Further, the displacement gear position-limit mechanism is the connecting rod set of rigidity, and cylinder covers on connecting rod, both ends respectively with brush Head and rotation gears slip contact, while connecting rod set is fixedly connected with the gear shaft of displacement gear.Due to brush head, rotation gear with Connecting rod is fixedly connected, therefore connecting rod covers the constraint on length of connecting rod direction by brush head and rotation gear, so that connecting rod set is certainly Body and installing connecting rod cover upper displacement gear and move synchronously with connecting rod.

Further, elastic damping part is set in the brush handle component, to increase connecting rod and brush head relative to hollow brush The resistance to sliding of handle adjusts the amplitude and rhythm of rod slide, and rod slide and the propulsion of toothbrush entirety is enable to carry out simultaneously.

Further, the elastic damping part is one kind of spring, elastic slice or elastic polymer material.

Further, brush head and connecting rod are to be fixedly connected or grafting.

Further, when the cylindrical round brush for forming brush head is single, rolling is fixed in the connecting rod and round brush connecting pin Brush spine bottom shaft core position；When the round brush for forming brush head is multiple, round brush bottom surface is fixed to install driven gear, the rolling of the connecting rod additional Brush connecting pin and install driving gear additional, driving gear and each driven gear engage respectively, and by a sheath body by all gears about Beam is on same plane axis, so as to so that the rotation of connecting rod rotates while driving multiple round brush.Multiple round brush can be fixed on Single plane arrangement, can also be realized the bending of brush head clean surface using modes such as hinge links according to teeth patterning, facilitate progress Multi-angle cleaning.

The beneficial effects of the utility model are:

When brushing teeth, hand-held tooth-brush handle protrudes into oral cavity, makes brush head along dental surface linear advancement or pull-out.Due to hollow brush Handle is to be slidably connected, therefore brush head and the brush head being attached thereto rotation control assembly can be because in teeth with brush handle rotation control assembly Resistance that surface is subject to and generate relative displacement with hollow brush handle, pass through the rack structure in hollow brush handle and drive displacement gear rotation Turn, and then drive rotation gear and link rotatable, realizes the rotation of brush head.To the simple action to hold toothbrush linear advancement The disposable friction cleaning for realizing twocouese, it is simple and efficient to handle, without other power such as power supply.

The rotary rolling brush of composition brush head has bigger usable floor area, and service life can be improved；Meanwhile according to the vertical of tooth Body constructs be arranged side by side two or even multiple round brush, and effectively cleaning area can be improved with lesser round brush diameter, avoid excessive straight The round brush of diameter touches inner buccal surfaces, and brush head can be further realized when brushing teeth by different arrangement modes to the more of tooth Angle cladding, disposably completes the cleaning in multiple faces, to greatly improve brushing efficiency.

Furthermore it is possible to be put down by adjusting the transmission ratio and the suitable elastic damping part of addition of displacement gear and rotation gear The linear advancement speed and velocity of rotation of weighing apparatus brush head, optimize using effect.
