PHOTOTHERAPY CARE TOOTHBRUSH

Abstract

A phototherapy care toothbrush is provided. The phototherapy LEDs are arranged in the toothbrush head body. The phototherapy LEDs are used to emit phototherapy ray with a specific wavelength to assist in oral cleaning and oral care, so that a deep cleaning and care effect can be achieved. Furthermore, redundant chemical medicines can be effectively prevented from entering an internal system of a person from the mouth to harm the health. In addition, in conjunction with various optimization solutions, such as using the bristle base made of a light-transmittance material to refract and guide light to adjust an illumination region, using bristles made of light guide fibers to perform low-loss and high-efficiency light guidance, and covering a light reflection layer at an inner surface of the toothbrush head accommodating chamber to enhance the illumination intensity, the oral phototherapy effect is greatly enhanced.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure but not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skilled in the art without creative efforts fall within the protection scope of the present disclosure.

[0022] Referring to FIG. 1 to FIG. 2, a phototherapy care toothbrush includes a toothbrush head 1 and a toothbrush handle 2. The toothbrush head 1 is detachably connected to the toothbrush handle 2. A toothbrush head body 11 is arranged at one end of the toothbrush head 1, and a connecting end piece 19 is arranged at the other end. The toothbrush head 1 is detachably connected to an output shaft of a driving motor 25 on the toothbrush handle 2 through the connecting end piece 19. The toothbrush head body 11 includes a toothbrush head accommodating chamber 13 and a bristle base 16 covered at an opening of the toothbrush head accommodating chamber 13. The bristle base 16 is encapsulated at an opening of the toothbrush head accommodating chamber 13 by an ultrasonic process, and the bristle base 16 is connected to the toothbrush head accommodating chamber 13 in a water sealing manner. Bristles 17 are arranged on one side of the bristle base 16 away from the toothbrush head accommodating chamber 13. Ends of the bristles 17 away from the toothbrush head accommodating chamber 13 extend out and are placed outside the bristle base 16, and ends facing the toothbrush head accommodating chamber 13 penetrate through the bristle base 16 and are communicated to the toothbrush head accommodating chamber 13. A light emission lamp panel 15 is arranged in the toothbrush head accommodating chamber 13. The light emission lamp panel 15 is encapsulated with phototherapy LEDs 151. The phototherapy LEDs 151 include blue-light LEDs and red-light LEDs; a light wavelength of the blue-light LEDs is 400 to 460 nm; and a light wavelength of the red-light LED is 630 to 660 nm. Blue light in this wave band can effectively whiten the teeth, and red light in this wave band can effectively perform anti-inflammatory oral care. A direction of light emission of the phototherapy LEDs 151 is towards one side of the bristle base 16. An inner surface of the toothbrush head accommodating chamber 13 is covered with a light reflection layer 14. The light reflection layer 14 can reflect light of a diffuse reflection part of the phototherapy LEDs 151 towards the bristle base 16 to enhance the light intensity. The bristle base 16 is a light-transmittance member. A refractive index of the bristle base 16 can be adjusted according to an actual illumination range during the design of the product, so as to enlarge or narrow an illuminated region of phototherapy ray. The bristles 17 are light guide fibers. The light guide fibers can efficiently and accurately guide the ray to the teeth, which is beneficial to enhance the phototherapy care effect and reduce propagation loss of the ray. The toothbrush head 1 and toothbrush handle 2 are electrically connected to each other through an electrical connection mechanism. The electrical connection mechanism includes a power receiving coil 18 arranged in the toothbrush head 1 and a power transmitting coil 22 arranged on the toothbrush handle 2. The power receiving coil 18 and the power transmitting coil 22 are wirelessly electrically connected to each other.

[0023] The toothbrush head 1 includes a toothbrush head housing 12. The toothbrush head accommodating chamber 13 is formed in one end of the toothbrush head housing 12, and a conical cavity is formed in the other end. The connecting end piece 19 is embedded in the conical cavity. The power receiving coil 18 is arranged on one side of the connecting end piece 19 facing the conical cavity. The toothbrush handle 2 includes a handle housing 21. The handle housing 21 is a sleeve with openings provided in two ends. An upper end plug 24 is arranged at the opening in the upper end of the handle housing 21. The driving motor 25 is mounted in the handle housing 21. An output shaft of the driving motor 25 penetrates through the upper end plug 24 and extends outwards from the opening in the upper end of the handle housing. The upper end plug 24 is provided with the power transmitting coil 22, and the power receiving coil 18 is wirelessly electrically connected to the power transmitting coil 22.

[0024] An electrical appliance support 28 is arranged in the handle housing 21. The electrical appliance support 28 includes a motor support 281 and a battery support 282. An end portion of the motor support 281 and an end portion of the battery support 282 opposite to the end portion of the motor support 281 are connected in an inserted manner. A circuit board assembly 29 and a storage battery 26 are arranged in the handle housing 21. The driving motor 25, the storage battery 26, and the circuit board assembly 29 are fixedly mounted on the electrical appliance support 28. A waterproof cover 23 is encapsulated at the opening in the upper end of the handle housing 21. The waterproof cover 23 sleeves the output shaft of the driving motor in a circumferentially direction and is clamped between the upper end plug 24 and the handle housing 21. A bottom end plug 27 is encapsulated at the opening in the lower end of the handle housing 21. A power input port is arranged on the bottom end plug 27. The power input port is electrically connected to the circuit board assembly 29. The circuit board assembly 29 is electrically connected with control buttons 291 and indicator lights 292. The control buttons 291 and the indicator lights 292 are arranged in preset through holes of the handle housing 21. The control buttons 291 are configured to adjust a working mode of the driving motor 25 and a working mode of the phototherapy LEDs 151. The indicator lights 292 are configured to display a real-time working mode of the electric toothbrush.

[0025] In summary, according to the present disclosure, the phototherapy LEDs 151 are arranged in a toothbrush head body 11. The phototherapy LEDs 151 are used to emit phototherapy ray with a specific wavelength to assist in oral cleaning and oral care, so that a deep cleaning and care effect can be achieved. Furthermore, redundant chemical medicines can be effectively prevented from entering an internal system of a person from the mouth to harm the health. In addition, in conjunction with various optimization solutions, such as using the bristle base 16 made of a light-transmittance material to refract and guide light to adjust an illumination region, using the bristles 17 made of light guide fibers to perform low-loss and high-efficiency light guidance, and covering the light reflection layer 14 at the inner surface of the toothbrush head accommodating chamber 13 to enhance the illumination intensity, the oral phototherapy effect is greatly enhanced, and a need of a user for deep oral care.
