Description

The protective type electric toothbrush device

This utility model relates to a kind of protective type electric toothbrush device, belongs to the technical field of electric toothbrush.

Existing teeth brushing way, be divided into manual and electric tooth brushing two classes, manual brushes, efficient is low, horizontal brush is residue between the easy-clear slot not, weak effect cleans the teeth, though the more horizontal brush of perpendicular brush is easy to remove tartar, but be easy to cause peeling off of gingiva and tooth, brush also is easy to damage organs such as oral cavity wall when frequently moving in the oral cavity, so that cause oral inflammation, electric toothbrush has begun to come out at six the seventies, but must not promote, mainly contain rotary (wheeled and cluster type) and vibration-type, thousands of high frequency brushes of per minute motion only have hundred times manual toothbrush superior than per minute really, the efficient height, structurally also there is defective together, for example, wheeled or cluster type rotational head is difficult to remove tartar between slot, and up-down vibration formula brush easily causes peeling off of gingiva and tooth, and the brush of high-speed motion very easily damages and stimulates tender oral cavity organs under the situation that does not have to protect, and the price of electric toothbrush is higher, approximately about 500-600 unit, also make the resident be difficult to accept, structurally not seeing so far has much improvement.

The purpose of this utility model is that a kind of protective type electric toothbrush device will be provided, it can overcome above-mentioned shortcoming, adopt the spiral column brush of many groups, make full use of the principle of screw propulsion, can dispose the thorough degree of tartar between slot, brush and oral cavity wall that safe refuge floor can be isolated high speed rotating effectively are housed, make its unlikely being upset, safety and comfort when having guaranteed to brush teeth, overall structure is more succinct, and cost is reduced.

The purpose of this utility model is achieved in that

A kind of protective type electric toothbrush device, has brush holder, accumulator and motor are equipped with in its inside, switch is equipped with on the brush holder surface, it is characterized in that power transmission shaft (7) one ends are connected with motor reel, the other end connects a gear (8), this gear (8) and d-axis cylindricality gear (9) engagement, mesh with the co-axial bevel gear of gear (9) (10) bevel gear (11), on the axle of bevel gear (11) a brush (12) is housed in addition, this diaxon all is supported on above the bearing support (13), and 4 brushes arranged side by side (12) (20) (21) (22) are housed in the refuge floor (1) altogether, and its bottom of bevel gear (10) (14) (15) (16) all is to be connected with a roller gear to be meshed successively.

The bristle of brush (12) (20) (21) (22), its first half are that left-hand screw shape is arranged, and Lower Half is that right-hand screw shape is arranged;

Refuge floor (1) can be that the more than half part of brush is surrounded.

Now in conjunction with the accompanying drawings the structure of humorous note formula electric tooth brushing device is described in detail:

By Fig. 1, tooth brushing device is combined into one by brush holder (2) and refuge floor (1), accumulator (4) and motor (5) are equipped with in brush holder (2) inside, be connected with lead with the switch (6) on the brush holder (2), power transmission shaft (7) one ends one directly are connected with motor shaft, the other end is equipped with a gear (8), mesh with d-axis cylindricality gear (9), with co-axial bevel gear of gear (9) (10) and bevel gear (11) engagement, adorn a brush (12) in addition on the axle of bevel gear (11), this diaxon all is supported on above the bearing support (13), and refuge floor (1) can surround the more than half part of brush.

For refuge floor (1) can be turned an angle around brush holder,, correspondingly use a support the cardan-shaft suspension (not shown) so can on power transmission shaft, add a break-in joint.

By Fig. 2,3,4 brushes arranged side by side (12) (20) (21) (22) are housed in the refuge floor (2) altogether, bevel gear (10) (14) (15) (16) bottom all is connected with roller gear and engagement, it is consistent with (22) rotation direction on its axle 4 brushes (12) to be housed side by side, and two brush (20) (21) is just in time opposite in addition; Brush (12) (20) (21) (22) surface, the first half is that left-hand screw shape is arranged bristle, the lower portion but is that right-hand screw shape is arranged its bristle, when brushing teeth, because the direction of rotation of brush is different, bristle arranges that by the left and right sides hand of spiral residues such as its tartar discharge together with the middle part of toothpaste fluid by bristle, so toothbrushing effect is significantly good again.

Gear (8) can be spherical gear or ordinary gear, and refuge floor (1) can be protected the oral cavity wall, and bristle can not contacted, and damage oral cavity wall.

Compared with prior art, protection-type electric tooth brushing apparatus has following advantages:

1, refuge floor and brush holder can be swung certain angle in use, make brush can reach institute There is the effect of protection oral cavity wall at the position of soft brush, refuge floor, make bristle can not touch oral cavity wall device.

2, brush turns to difference, and the bristle configurations direction is also arranged by the left-and-right spiral line, brushing effects Significantly good.

Claims (3)

1, a kind of protective type electric toothbrush device, has brush holder, accumulator and motor are equipped with in its inside, switch is equipped with on the brush holder surface, it is characterized in that power transmission shaft (7) one ends are connected with motor reel, the other end connects a gear (8), this gear (8) and d-axis cylindricality gear (9) engagement, mesh with the co-axial bevel gear of gear (9) (10) bevel gear (11), on the axle of bevel gear (11) a brush (12) is housed in addition, this diaxon all is supported on above the bearing support (13), and 4 brushes arranged side by side (12) (20) (21) (22) are housed in the refuge floor (1) altogether, and its bottom of bevel gear (10) (14) (15) (16) all is to be connected with a roller gear to be meshed successively.
