Description
Technical field
The present invention relates to toothbrush, particularly relate to toothbrush with controlled head movement and the method for locating toothbrush head.
Background technology
Traditional toothbrush comprises a plurality of the same bristle tufts, and every cocooning tool has one first end and one second end, and first end is held and is captured in the toothbrush head and is fixed in the latter, and second end is free end and is used to brush teeth.Different bunches free end constitutes an enveloping surface, and this enveloping surface can the distortion a little by means of bristle is crooked when touching by the brush surface, but can not cooperate a surface with complicated shape fully.Such complex surface occurs in mouth, and tooth generally is in " C " shape case of bending in upper and lower jaw herein, and therefore every row's tooth has the outer bend and the recessed interior curve of protrusion.
In the process of brushing teeth, the user makes hope that bristle is fit to tooth express by the curved profile that operate toothbrush effectively makes bristle suitably be deformed into denture.Thisly just cause the excessive wear of the flank of tooth and gum, and toothbrush conforms to suitably so that required cleaning is provided with tooth near the strong operation of tooth.
It is disclosed in the prior art so that make bristle meet the toothbrush of dentition profile to have a deflection neck between toothbrush head that contains bristle and handle.The example of this deflection neck toothbrush is included in United States Patent (USP) 759,490 and 4,520, the multiple toothbrush that discloses in 526.It is flexible that United States Patent (USP) 759,490 is created neck by means of placement deflection elastomeric material between rigid head portion and handle, and this deflection elastomeric material can strengthen with second kind of this type material.And that United States Patent (USP) 4,520,526 is created neck by means of following alternative method is flexible: or take a part of material away from the top and bottom portion of toothbrush stem, or in neck, have an oval hole that reaches opposite side from a side.This deflection elasticity toothbrush stem allows bristle head relative curved handle when the user applies excessive strength, reduces the danger of damage tooth and gum whereby.Yet this flexing method does not allow the user to have following ability: the special semicircle in oral area surface that control toothbrush head profile becomes cleaning with water, and to avoid in first example, applying the needs of excessive strength.
United States Patent (USP) 4,333,199 disclose a kind of toothbrush, and its head can pivotally be installed on the helical spring that is positioned at recessed handle top, so that be suitable for rotating when head is applied on the tooth and inclination.Yet in the oral area surface semicircle that this deflection action can allow toothbrush head roughly to follow just to be cleaned with water, it does not provide by the directly actuated toothbrush head motion of user, inclination and spinning movement.
PCT International Application No. WO 89/10076 discloses a kind of toothbrush, and it has angle between the toothbrush head of change and the handle so that the location toothbrush head makes it the ability parallel with the denture arch section.WO 89/10076 discloses a kind of toothbrush, and it has the handle that can be pivotally connected to head, handle is made of the upper and lower sidepiece of a pair of rigidity that separates herein, and these sidepieces can pivotally link together and can vertically move mutually.As an alternative, the upper and lower sidepiece of the rigidity that separates can connect by an elasticity interlayer, and this also allows them can vertically move mutually.Use a kind of like this by toothbrush rigidity sidepiece the handle that can pivotally connect that vertically moves control and head accurately to control the toothbrush head position be difficult at most.It is because the following fact that this accurate control lacks: the connection that can pivot lacks rigidity or resistance, has the trend that makes the toothbrush head overexercise; Move with extent of elasticity and substitute to use an elastic layer can limit head with being directly proportional.
Therefore, have a kind of like this demand in toothbrush art: the user can more accurately control the position of toothbrush head, so that head is positioned to the state that conforms to the denture curved profile.
