Description

Six turning handle formulas of double end toothbrush

The utility model relates to a kind of toothbrush of cleaning teeth.

Existing various toothbrush constitutes by brush holder and band brush head.Modal be a kind of bristle be single face be hardwired toothbrush with brush holder.This toothbrush when brushing teeth, need repeatedly change bristle towards the interior lateral surface that comes to clean respectively one by one upper and lower tooth and chew the face of stinging, action is many, time-consuming length, and the medial surface of tooth is subjected to angle limits to make bristle be difficult to touch and is difficult for cleaning with water clean.For solving this deficiency, Chinese patent bulletin CN2052638 discloses a kind of " tooth brush for health protection of U type ", is made of with a U type brush of fixedlying connected with brush holder brush holder, and bristle is distributed on three medial surfaces of U type brush.The less than one of this U type toothbrush is still to need the single respectively brush of upper and lower tooth, the 2nd, and be three faces that the fixed U type brush that is connected is difficult to be implemented in the camber gum with brush holder and come up back into the row brushing.

The purpose of this utility model is the above-mentioned shortcoming that overcomes existing toothbrush, provide a kind of six facings can finishing upper and lower tooth simultaneously clean with water and save time, six turning handle formulas of labour-saving double end toothbrush.

Six turning handle formulas of double end toothbrush of realizing the utility model purpose is made of brush holder and band brush head, described band brush head is the symmetrically arranged U type of leaning shape groove shape brush by two and constitutes, one end of described brush holder is stretched between the bottom of two groove shape brushes, is radial type with brush and is connected.When brushing teeth upper and lower tooth placed respectively in the groove of two groove shape brushes that lean against setting, the bottom of groove shape brush and the bristle of two medial surfaces then respectively with upper and lower tooth chew the face of stinging and inside and outside side touches mutually, push-and-pull brush holder back and forth in the usual way, then can arbitrarily rotate with the brush that is articulated and connected with brush holder, make brush come backwash capable and finish scrubbing simultaneously six faces along six faces of tooth with respect to brush holder.

Hinged between described brush holder and the brush, can adopt simply establish the hole on the brush holder, the two ends of peg graft in the hole cylinder, cylinder are fixed in the version of the bottom of two U type groove shape brushes respectively.Also can adopt spherical hinge version, reduce the angle limits that brush holder moves back and forth, make its operation more free and relaxed.

The thickness of considering the tooth between front tooth and the molar differs, the optional usefulness of brush body has certain flexible plastic material manufacturing, utilize the elasticity of plastics to make the opening Zhang Du of groove shape brush possess that the two sides that certain elasticity guarantees brush " are strutted ", its opening " contraction " again thereupon when brushing to front tooth when brushing to molar, thereby guarantee that bristle all keeps the situation that touches of appropriateness at the volley with each tooth face.Also can be embedded an elastic component in the brush body makes the two sides of brush possess certain elasticity to guarantee that bristle contacts with the good of tooth.

Still the shape of U type groove shape brush body can be become and the similar camber shape of gum along its axial design, can reduce brush on the one hand, also can increase its comfort on the other hand at the tooth face capable resistance of backwash that comes up.

The utility model only need be handled brush holder back and forth and can drive brush brush row on dental surface, can finish scrubbing six exposed faces of upper and lower tooth simultaneously.The efficient height, action is few, operates free and relaxed.Being suitable for various age bracket people uses.

Provide embodiment below in conjunction with accompanying drawing.But content of the present utility model is not limited in this embodiment.
