Description

FIELD OF THE INVENTION



[0001] The present invention relates to toothbrush, more particularly, to a compact ozone toothbrush.

BACKGROUND OF THE INVENTION



[0002] There are different designs for ozone toothbrush with bactericidal functions. However, the current ozone toothbrushes have complicated structures and bad versatility, can't satisfy people's various demands of functions. For example, it is hard to be accepted that the brush head can't be changed conveniently, and the power consumption of the toothbrush by using battery only is so high. Meanwhile, the high cost is also hard to be accepted. So, the popularization and usage of the ozone toothbrush are affected directly. Furthermore, the conventional toothbrushes also have complicated structure and large size.

SUMMARY OF THE INVENTION



[0003] An aspect of the present invention is to provide an ozone toothbrush with compact structure, which enables a limited amount of ozone to be used in the toothbrush without leaking. Meanwhile, the defect of complicated structure of the conventional ozone toothbrush due to a need of pressurized gas is eliminated. And a sufficient flexibility for the structure of the toothbrush, such as recharging and oscillating, are also considered.

[0004] According to an aspect of the present invention, a compact ozone toothbrush is provided, comprising a handle portion and a bristle portion, wherein the compact ozone toothbrush also comprises an ozonizer and a circuit provided inside the handle portion to enable operation of the ozonizer.

[0005] Advantageously, the compact ozone toothbrush also comprises batteries used for power supply to the circuit, and a switch for controlling the power supply.

[0006] Advantageously, the handle portion further comprises a handle and a connecting pole, wherein the ozonizer is installed in the bristle portion or the connecting pole, and the circuit is placed in the connecting pole, and the batteries are placed in the handle.

[0007] Advantageously, the handle portion further comprises a handle and a connecting pole, wherein the ozonizer is installed in the bristle portion or the connecting pole, and the circuit and the batteries are placed in the handle.

[0008] Advantageously, the ozonizer comprises a metal discharge device, or an ozonizer tube, or a ceramic element.

[0009] Advantageously, the bristle portion comprises a base board, several binds of bristles on the base board, and when the ozonizer is installed in the bristle portion, the bristle portion also comprises a shell for receiving the ozonizer.

[0010] Advantageously, the base board is movably connected to the shell, and the shell is fixed to the handle portion.

[0011] Advantageously, the bristle portion further comprises an outer shell, forming a cavity with the base board to receive the ozonizer, and overflow vents or overflow slots are provided on the base board or the outer shell.

[0012] Advantageously, a removable battery cover or a removable battery box is provided at a free end of the handle portion.

[0013] Advantageously, the batteries are rechargeable batteries, and the compact ozone toothbrush also comprises induction coils wound around the handle portion, and an induction charging circuit connected between the induction coils and the rechargeable batteries.

[0014] Advantageously, the compact ozone toothbrush also comprises an oscillating unit powered by the batteries, which provides oscillation to the toothbrush, and the oscillating unit may be an eccentric motor.

[0015] The ozone toothbrush provided in the present invention has the following prominent advantages: since the generated ozone is directly applied to the bristle portion of the toothbrush, no gas-pressurized equipment is needed, thus the size of the ozone toothbrush may be very small. Meanwhile, a sufficient flexibility for the structure are also considered, for example, the brush head is changeable, the batteries are rechargeable, and the toothbrush is vibratile.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT



[0017] As shown in Fig.1, the compact ozone toothbrush according to the first embodiment of the present invention comprises a handle portion and a bristle portion 2. An ozonizer 3 is installed inside the bristle portion 2. The handle portion further comprises a handle 1 and a connecting pole 4. A driving circuit 5 of the ozonizer 3 is placed inside the connecting pole 4. Batteries 6 are used for power supply to the driving circuit 5, and a switch 7 is used to control the power supply of the batteries. Both of the batteries 6 and the switch 7 are placed in the handle 1. The ozonizer may be a metal discharge device, or an ozonizer tube, or a ceramic element. The batteries may be rechargeable batteries. Induction coils (not shown) are wound around the handle portion, and an induction charging circuit used to charge the rechargeable batteries through a outside induction equipment is connected between the induction coils and the rechargeable batteries.

[0018] As shown in Fig.2, the compact ozone toothbrush according to the second embodiment of the present invention comprises a handle portion and a bristle portion 2. The handle portion further comprises a handle 1 and a connecting pole 4. An ozonizer 3 is installed inside the connecting pole 4. A driving circuit 5 of the ozonizer 3 and batteries as well as a switch 7 for controlling the power supply to the batteries are all placed inside the handle 1.

[0019] As shown in Fig.3, the compact ozone toothbrush according to the third embodiment of the present invention comprises a handle portion and a bristle portion 2. An ozonizer 3 is installed inside the bristle portion 2. The handle portion further comprises a handle 1 and a connecting pole 4.
