[0034] Embodiments of the invention
[0035] Figure 1 is a schematic diagram showing a functional block diagram of a light irradiation sanitation device based on a PCB-attached motor according to an embodiment of the present invention; Figure 2 is a schematic diagram showing a functional block diagram of a main body of a light irradiation sanitary device based on a PCB-attached motor according to an embodiment of the present invention; Figure 3is a schematic diagram showing a functional block diagram of a PCB component of a light irradiation sanitary device based on a PCB-attached motor according to an embodiment of the present invention; Figure 4 FIG. 1 is a schematic diagram showing a perspective view of a light irradiation sanitary device based on a PCB-attached motor according to an embodiment of the present invention. Figures 1 to 4 As shown, according to one embodiment of the present invention, a light irradiation sanitary device (100) based on a PCB-attached motor includes a body (110), a PCB (120), a vibration motor (130) and a bristle plate (140).
[0036] The main body (110) is a part that constitutes the outer appearance of the handle (111) and the brush head (112). The handle (111) of the main body (110) is the part where the user holds the toothbrush, and the power button (121) can be exposed in this area. In the brush head (112) of the main body (110), bristles (141) and massage bristles (142) composed of a wave-guide described later, and a light source (122) are arranged. Light emitted from the light source can be transmitted to the user's teeth or gums through the bristles (141).
[0037] The PCB (120) is a printed circuit board designed according to the shape of the main body (110) and arranged inside the main body (110). The handle area is provided with a power button (121), and the brush head area forms a light source part (122) including multiple light sources, which emits light through a light guide. The PCB (120) can be designed with a single-piece structure corresponding to the shape of the main body (110). Different from the traditional multiple or divided PCB structure, the single-piece structure can simplify the manufacturing process and reduce costs.
[0038] In addition, the PCB (120) may further include a battery connector (123) arranged and formed inside the handle portion (111) of the body portion (110). At the same time, the light source portion (122) of the PCB (120) includes a first light source (122a) emitting short-wave light and a second light source (122b) emitting long-wave light. The plurality of light sources may form the following structure: a set including at least one first light source (122a) emitting short-wave light, and a set including at least one second light source (122b) emitting long-wave light.
[0039] In addition, the light source unit (122) may be composed of a structure in which a plurality of light sources are repeatedly arranged. The light source unit (122) includes a first light source (122a) that emits short-wave light and a second light source (122b) that emits long-wave light. The short-wave light emitted by the first light source (122a) is blue light, and the long-wave light emitted by the second light source (122b) is red light. The light source unit (122) may emit not only red light or blue light, but also ultraviolet light, infrared light or light in other non-visible light bands, such as yellow light or green light.
[0040] In addition, the first light source (122a) and the second light source (122b) in the light source unit (122) can be composed of light emitting diodes (LEDs) or laser diodes (Laser Diodes).
[0041] The vibration motor (130) is located in the upper end area of the handle portion (111) of the main body (110) and is attached to the PCB (120) by welding. By designing the vibration motor (130) as an attached structure, the noise generated by vibration when the electric toothbrush is used can be reduced, and its functionality can be improved by increasing the vibration stability. In other words, compared with the traditional separate motor, the design of fixing the motor on the PCB (120) helps to reduce noise and increase vibration stability, thereby improving the convenience of use. The vibration motor (130) can generate vibration in the light irradiation sanitation device (100) to exert the function of the electric toothbrush.
[0042] The bristle plate (140) is located above the light source part (122) formed in the brush head area of the PCB (120) and is fixed, and is equipped with at least one bristle (141) formed by a light guide tube. The bristles (141) equipped with the bristle plate (140) are formed by the light guide tube, and the light guide tube can be made of optical fiber material.
[0043] Figure 5 is a schematic diagram showing the positional relationship between a PCB light source portion and a bristle plate in a light irradiation sanitary device based on a PCB attached motor according to an embodiment of the present invention; Figure 6 is a schematic diagram showing a combination state of a light source portion and a bristle plate in a light irradiation sanitary device based on a PCB-attached motor according to an embodiment of the present invention; Figure 7 FIG. 1 is a schematic diagram showing a plan view of a bristle plate in a light irradiation sanitary device based on a PCB-attached motor according to an embodiment of the present invention. Figures 5 to 7 As shown, the bristles (141) include at least one light guide tube for transmitting the light emitted by the light source to the outside. Here, the light guide tube refers to a tubular structure having the function of transmitting the light emitted by the light source. The bristles (141) can transmit the light emitted by the light source to the user's teeth, and the bristles (141) using the light guide tube can be made of optical fiber material.
[0044] In addition, the massage hair (142) can also be manufactured using a light guide. The massage hair (142) is a bristle used to massage the user's gums, and it can transmit the light emitted by the light source, thereby massaging the user's gums, the inside of the cheek or the tongue. In order to better transmit the light emitted by the light source, the massage hair (142) can also be made of an optical fiber bundle. Since the optical fiber needs to have a specific diameter in order to effectively transmit light, the massage hair (142) can be formed by assembling the optical fiber bundle into a set, and this structure is achieved by inserting the optical fiber bundle set into the capsule of the massage hair (142).
[0045] In addition, the bristle plate (140) formed by the bristles (141) and the massage bristles (142) arranged on the brush head (112) of the main body (110) can be designed as a detachable structure, so as to facilitate replacement according to usage requirements.
[0046] like Figure 7 As shown, the bristles (141) can be arranged at both ends of the bristle plate (140) in the length direction with bristles (141d) that are longer than other bristles (141a, 141b, 141c, 141e) so as to better illuminate the user's molars. The other bristles (141a, 141b, 141c, 141e) can be designed as a rectangle according to the arrangement of the light source. In addition, the massage hairs (142) can be arranged around the center of the elliptical bristle plate (140) and arranged at the four corners of the virtual rectangle, specifically for massaging the gums. The light source part (122) can emit blue light to produce oral sterilization or teeth whitening effects; it can also emit red light to achieve anti-inflammatory effects, promote collagen production and other effects. In addition, the first light source (122a) and the second light source (122b) of the light source part (122) can be arranged alternately to enhance the intensity of the light and produce an enhanced interference effect of the light.
