Abstract

The invention relates to a dental turbine handheld drill, which includes a machine head shell and a machine core disposed in the machine head shell. The machine core composes a generator, which is connected to an LED lamp mounted outside a drilling needle socket of the machine head shell. The LED lamp is in connection with a power supply disposed in the machine head shell. The involved battery is an annular battery. The invention solves the problem that a circuit cannot be disposed in the machine head. By making use of the No. 200510020493.6 patent, lamp filaments are arranged in a ring, so that the light at a drill bit cannot be shielded. The power supply employs the battery and has a low cost, thus being suitable for single use. A one-way valve is set to prevent and control inverse suction of dirt so as to avoid cross infection. Meanwhile, the one-way valve is used as the switch of the battery supply, thus realizing dual-use. A magnetic bearing is arranged, and a magnetic permeability material can be a plastic magnetic permeability material and is easy for molding.

The specific embodiment

Like Fig. 1, hand-held the boring of a kind of tooth section's turbine is made up of handle 1 and head 2, and the turbine in the head 2 is a magnet turbine 3, and magnet turbine 3 external fixation coils 4 constitute electromotor; Electromotor connects LED lamp 5, and the LED lamp is arranged on outside the housing of head, is positioned at the head bottom.Head covers in the head bottom among the figure, and the head lid also can be on head top.

Like Fig. 2, hand-held the boring of 3 described tooth section's turbines, the axial and magnet turbine 3-1's of said coil 4-1 is axial vertical, and the interior center of turbine magnetic line of force direction is axial vertical with the magnet turbine.This is the most easy electromotor, but is fit to handpiece structure.

Bore as the described tooth of Fig. 4 section turbine is hand-held, said magnet turbine was three range upon range of adding, and three layers of magnet turbine are respectively 3-1-1,3-1-2,3-1-3 formation Haier Bake Halbach array.Increase like this and mould the magnetic material at coil magnetic flux.

Bore as the described tooth of Fig. 5 section turbine is hand-held, coil 4-2 is two and is arranged on same plane, the axially parallel of the axial and magnet turbine 3-2 of coil.This is exactly the electromotor that No. 02251204.7 magnet and induction coil in the patent constitutes.

Bore as the described tooth of Fig. 6 section turbine is hand-held, the axle of said coil 4-3 overlaps with the axle of magnet turbine 3-2, and magnet turbine 3-2 and coil 4-3 constitute the parts of claw pole electric generator.Remaining structure is a prior art constructions, there is no need to be described in detail.

The coil 4-3 of said claw pole electric generator; Place magnet turbine 3-2 downside, the upside of coil 4-3 is provided with claw-like chip 6-1, and the downside of coil 4-3 is provided with claw-like chip 6-2; Claw-like chip 6-1 intersects with the pawl of claw-like chip 6-2, and claw-like chip 6-1 is connected with the centre of claw-like chip 6-2.
