Detailed Description of the Invention

[0001] 〔Technical Field〕 The present invention relates to a light irradiation hygiene device including a PCB (printed circuit board) directly assembled to a main body, and more specifically, to a light irradiation hygiene device including a PCB directly assembled to a main body such that a PCB constituting an electric toothbrush and having a vibration motor attached thereto is directly assembled to a rib inside the main body. 〔Background Art〕 Generally, in order to hygienically manage teeth, as methods for removing oral bacteria that cause dental plaque and tartar, a method of brushing teeth using a toothbrush or a method of using a mouthwash containing a chemical antibacterial agent after brushing teeth are mainly used. Many electric toothbrushes are sold as an effective method of brushing teeth. In addition, since bacteria cannot be effectively removed by ordinary brushing alone, electric toothbrushes that irradiate light in a specific wavelength band have also been disclosed. However, generally, only a chemical removal method using an oral cleaner is used, and although electric toothbrushes that emit light that has been disclosed irradiate white light, many blue and red LED electric toothbrushes have recently been sold, but there is a problem in that no specific method for effectively suppressing oral bacteria has been presented.

[0002] In particular, existing electric toothbrushes are configured to have an antibacterial function of irradiating light and include a vibration motor inside, but the vibration motor is arranged in a plastic housing, physically separated from the substrate, and assembled, and usually consists of three PCBs: a substrate on which a light source is formed, a substrate to which the vibration motor is connected, and a substrate to which a battery is connected.

[0003] Such existing electric toothbrushes have problems of increased cost and manufacturing processes due to the three-piece structure of the PCB with three substrates, increased noise during use, and decreased vibration stability.

[0004] Korean Registered Patent Publication No. 10-0773210 is disclosed as a prior art document. 〔Detailed Description of the Invention〕 〔Technical Problem〕 The present invention is proposed to solve the above-mentioned problems of the conventionally proposed methods. It includes a main body part that forms the housing appearance of the handle part and the head part, a PCB configured in a form corresponding to the shape of the main body part, arranged inside the main body part, with a power button formed in the handle part area and a light source part including a plurality of light sources that irradiate light through a waveguide formed in the head part area. A vibration motor is arranged in the upper end area of the handle part of the main body part and is attached to the PCB through soldering. A toothbrush bristle plate with toothbrush bristles formed by at least one waveguide is included and is located above and attached to the light source part formed in the head part area of the PCB. The PCB to which the vibration motor is attached is configured in a structure directly assembled to the internal rib (Rib) of the main body part, thereby reducing the noise using a PCB-mounted vibration motor, further improving the convenience of use through the noise reduction effect and the improvement of vibration stability due to the improvement of vibration stability, and providing a light irradiation hygiene device equipped with a PCB directly assembled to the main body.

[0005] Also, the present invention configures the multiple or divided structure in a conventional PCB into a one-piece structure and makes the PCB directly assembled to the internal rib of the main body part, thereby not only improving the cost competitiveness by reducing parts, but also improving the assemblability and assembly speed, and further realizing the improvement of durability through minimizing the cause of failures by reducing connecting parts due to direct assembly to the outer shape. Another object is to provide a light irradiation hygiene device equipped with a PCB directly assembled to the main body.

[0006] Furthermore, the present invention is configured such that a vibration motor is attached to the PCB and the PCB is assembled in a structure that contacts the outer shape of the main body part of the main body, thereby reducing the number of parts shaken by vibration and reducing noise, and enabling the simplification of the manufacturing process, cost reduction, and productivity improvement thereby.

This device is configured with a structure in which the PCB with the vibration motor attached is directly assembled to the internal rib of the main body part.

[0007] As a preferred configuration, the PCB is configured in a one-piece structure that can be arranged inside in a form corresponding to the shape of the main body part. By directly assembling the PCB to the internal rib of the main body part, the assemblability and assembly speed are improved, and the durability is improved by reducing the connecting parts by directly assembling to the main body.

[0010] As shown in FIGS. 1 to 7 respectively, an optical irradiation hygiene device (100) including a PCB directly assembled to a main body according to an embodiment of the present invention may include a main body part (110), a PCB (120), a vibration motor (130), and a toothbrush bristle plate (140). The main body part (110) is a configuration of the main body that forms the housing appearance of the handle part (111) and the head part (112). The handle part (111) of this main body part (110) is a part where the user holds the toothbrush, and the power button (121) can be exposed.

[0011] Here, in the head part (112) of the main body part (110), toothbrush bristles (141), massage bristles (142), and a light source part (122) composed of a waveguide (wave-guide) described later are arranged, and the light irradiated from the light source can be transmitted to the user's teeth, gums, etc. through the toothbrush bristles (141).

[0012] The PCB (120) is configured in a form corresponding to the shape of the main body part (110) and is arranged inside the main body part (110). It is a configuration of a printed circuit board in which a power button (121) is formed in the handle part area, and a light source part (122) including a plurality of light sources that irradiate light through a waveguide is formed in the head part area.

[0013] Such a PCB (120) is configured in a one-piece structure that can be arranged inside in a form corresponding to the shape of the main body (110), as shown in FIGS. 6 and 7 respectively. The PCB (120) has a structure that is directly assembled to the internal ribs of the main body (110). As a result, the assemblability and assembly speed are improved, and it has the function of improving durability by reducing the connecting parts due to being directly assembled to the main body. Here, different from the conventional multi-piece or split-structured PCBs, the PCB (120) configured in a one-piece structure can have the function of simplifying the manufacturing process and reducing costs. Also, the PCB (120) to which the vibration motor (130) is attached has a structure that is directly assembled to the internal ribs (Rib) of the main body (110). Such an assembly structure enables component reduction and, as a result, has the function of improving cost competitiveness. Furthermore, the PCB (120) to which the vibration motor (130) is attached is directly assembled to the outer shape of the main body (110), improving durability by eliminating the cause of failure due to component reduction and further improving noise reduction by reducing the number of components that shake due to vibration. Furthermore, the PCB (120) can have the function of improving assemblability and assembly speed and improving vibration transmission efficiency due to its structure of being directly assembled to the main body (110). Also, the PCB (120) can be configured to further include a battery connector (123) formed by being arranged inside the handle portion (111) of the main body (110). Furthermore, the light source portion (122) of the PCB (120) has a configuration including a first light source (122a) that irradiates short-wavelength light and a second light source (122b) that irradiates long-wavelength light. The plurality of light sources can be configured in a structure of a set including at least one first light source (122a) that irradiates short-wavelength light and a set including at least one second light source (122b) that irradiates long-wavelength light. Furthermore, the light source portion (122) can be configured in a structure in which the plurality of light sources are repeatedly arranged.Such a light source unit (122) includes a first light source (122a) that irradiates short-wavelength light and a second light source (122b) that irradiates long-wavelength light. The short-wavelength light irradiated from the first light source (122a) is blue light, and the long-wavelength light irradiated from the second light source (122b) can be composed of red light. Further, in addition to red or blue, the light source unit (122) can also be composed of ultraviolet light, infrared light in the invisible light region, or light in other visible light regions such as yellow and green. Furthermore, the light source unit (122) can be composed of the first light source (122a) and the second light source (122b) being LEDs (light-emitting diodes) or laser diodes. The vibration motor (130) is arranged in the upper end region of the handle portion (111) of the main body portion (110) and is configured to be attached to the PCB (120) by soldering. Such a vibration motor (130) is configured to be attached to the PCB (120), thereby reducing the noise caused by vibration during the use of the electric toothbrush and exhibiting the function of improving the stability of vibration. That is, by changing from the conventional motor-separated type to the integrated type fixed to the PCB (120), the convenience during use can be improved due to the reduction of noise and the improvement of vibration stability. Here, the vibration motor (130) can be made to function as an electric toothbrush by generating vibration in the light irradiation hygiene device (100). The toothbrush bristle plate (140) is located and attached above the light source unit (122) formed in the head portion region of the PCB (120) and is configured to include toothbrush bristles (141) composed of at least one light guide tube. Such a toothbrush bristle plate (140) includes toothbrush bristles (141) composed of at least one light guide tube, and the toothbrush bristles (141) composed of the light guide tube can be formed of optical fibers.

[0014] FIG. 8 is a diagram showing the positional relationship between the light source part of the PCB of the light irradiation hygiene device including the PCB directly assembled to the main body according to an embodiment of the present invention and the toothbrush bristle plate, FIG. 9 is a diagram showing the configuration of a state in which the light source part of the light irradiation hygiene device including the PCB directly assembled to the main body according to an embodiment of the present invention and the toothbrush bristle plate are combined, and FIG. 10 is a diagram showing the planar configuration of the toothbrush bristle plate of the light irradiation hygiene device including the PCB directly assembled to the main body according to an embodiment of the present invention. As shown in FIGS. 8 to 10 respectively, the toothbrush bristle (141) includes at least one waveguide, and irradiates the light irradiated from the light source to the outside. Here, the waveguide refers to a tube having the characteristic of transmitting the light generated by the light source. The toothbrush bristle (141) can transmit the light irradiated from the light source to the user's teeth, and the toothbrush bristle (141) using the waveguide can be manufactured and configured with an optical fiber. Also, the massage bristle (142) can also be manufactured using a waveguide. Here, the massage bristle (142) is a bristle used for massaging the user's gum, and can transmit the light irradiated from the light source to massage the user's gum, the inner side of the cheek, or the tongue, etc. Further, the massage bristle (142) can also be manufactured with a bundle of optical fibers in order to efficiently transmit the light transmitted from the light source. Also, since the optical fiber cannot have a diameter greater than a specific value in order to appropriately transmit light, the massage bristle (142) can be configured in such a way that a bundle of optical fibers is formed as one set and the set is inserted into the capsule of the massage bristle (142).

[0015] Furthermore, the toothbrush bristle plate (140) on which toothbrush bristles (141) and massage bristles (142) are formed has a detachable structure on the head portion (112) of the main body portion (110) and can be configured to be replaceable according to the usage situation. Further, as shown in FIG. 10, the toothbrush bristles (141) can be configured such that the toothbrush bristles (141d) located at both ends in the length direction of the toothbrush bristle plate (140) are longer than the other toothbrush bristles (141a, 141b, 141c, 141e) so as to effectively irradiate light on the back teeth. Further, the toothbrush bristles (141a, 141b, 141c, 141e) can also be configured to be arranged in a rectangular shape according to the arrangement form of the light source. The massage bristles (142) can be arranged at the vertex positions of a virtual rectangle surrounding the outer periphery thereof with reference to the center of the elliptical toothbrush bristle plate (140) and can be designed to massage the gums. Further, the light source unit (122) can exhibit a sterilization effect in the user's oral cavity and a tooth whitening effect by irradiating blue light. Also, by irradiating red light, it can have a function of exhibiting effects such as an anti-inflammatory effect and collagen production. Further, the plurality of light sources composed of the first light source (122a) and the second light source (122b) of the light source unit (122) can be arranged alternately so as to function such that the light intensity is improved by constructive interference. 〔Industrial Applicability〕 As described above, according to the light irradiation hygiene device including the PCB directly assembled to the main body according to an embodiment of the present invention, a main body portion forming the housing appearance of the handle portion and the head portion, and a form corresponding to the shape of the main body portion, which is arranged inside the main body portion, a power button is formed in the handle portion region, and a PCB including a light source unit including a plurality of light sources that irradiate light through a waveguide in the head portion region, a vibration motor arranged in the upper end region of the handle portion of the main body portion and attached to the PCB through soldering, and a toothbrush bristle plate provided with toothbrush bristles formed of at least one waveguide and located and attached above the light source unit formed in the head portion region of the PCB.

[0016] The structure is configured such that the PCB with the vibration motor attached is directly assembled to the internal rib of the main body, thereby reducing the noise caused by the PCB-mounted vibration motor, enhancing the noise reduction effect due to improved vibration stability, and further enhancing the convenience of use due to improved vibration stability. In addition, by integrating the conventional multi-piece or split-structured PCBs into a one-piece structure and adopting a structure in which the PCB is directly assembled to the internal rib of the main body, not only is the cost competitiveness improved by reducing parts, but also the assemblability and assembly speed are improved. Furthermore, by directly assembling to the main body, the number of connecting parts is reduced, minimizing the cause of failures and further improving durability.

[0017] In particular, by attaching a vibration motor to the PCB and assembling the PCB in a structure that contacts the outer shape of the main body, the number of parts shaken by vibration can be reduced, noise can be reduced, and the manufacturing process can be simplified, thereby enabling cost reduction and productivity improvement. The present invention described above can be variously modified and applied by those having ordinary knowledge in the technical field to which the present invention pertains, and the scope of the technical idea based on the present invention should be defined by the following claims.
