Abstract
Description
Technical Field
[0001] The present invention relates to a light irradiation hygienic device with a PCB (printed circuit board) directly mounted on a body. More specifically, the present invention relates to an electric toothbrush, characterized in that the PCB with a vibration motor can be directly mounted on a rib inside the body, thereby constituting a light irradiation hygienic device with a PCB directly mounted on the body. Background Art
[0002] Generally, in order to manage the hygiene of teeth, a method of brushing teeth with a toothbrush to remove oral bacteria that cause plaque and tartar formation is mainly adopted, or a method of using a mouthwash containing a chemical antibacterial agent after brushing teeth is used. In order to brush teeth more effectively, many electric toothbrushes have been launched on the market. In addition, since it is difficult to effectively remove bacteria only by conventional brushing, an electric toothbrush that can emit light of a specific wavelength is also disclosed. However, at present, only a chemical removal method using an oral cleaner is generally adopted, and although the disclosed luminous electric toothbrush can emit white light, blue light or red light LED light, a method that can effectively inhibit oral bacteria has not yet been specifically proposed, which has certain limitations. In particular, a conventional electric toothbrush generally includes a structure with a vibration motor inside and having a light irradiation antibacterial function, wherein the vibration motor is arranged in a plastic housing and assembled after being physically separated from a substrate, and includes a substrate forming a light source, a substrate connected to a vibration motor, and a substrate connected to a battery, and generally adopts a structure of three PCBs. This conventional electric toothbrush has a three-piece PCB structure with three substrates, which leads to increased costs and manufacturing processes, and increases noise and reduces vibration stability during use. As a prior art, Korean Registered Patent Publication No. 10-0773210 has been disclosed. Summary of the invention

[0033] Figure 7 is a schematic diagram of the front and back configurations of the PCBs of a light irradiation sanitary device with the PCB mounted directly on the body according to one embodiment of the present invention.
[0034] like Figures 1 to 7 As shown, according to one embodiment of the present invention, a light irradiation sanitary device (100) with a PCB directly mounted on the body may include: a body portion (110), a PCB (120), a vibration motor (130) and a bristle plate (140).
[0035] The body (110) is a body structure that forms the outer appearance of the handle (111) and the brush head (112). The handle (111) is the part where the user holds the toothbrush, wherein the power button (121) can be exposed. The brush head (112) of the body (110) is provided with toothbrush bristles (141) and massage bristles (142), which are connected to the light source (122) via a waveguide, and the light source transmits light to the user's teeth or gums via the toothbrush bristles (141).
[0036] The PCB (120) is designed according to the shape of the main body (110) and is arranged inside the main body. The PCB includes a power button (121) formed in the handle area and a light source part (122) located in the brush head area and emitting light through a waveguide. Figure 6 and Figure 7 As shown, the PCB (120) is an integrated structure and can be directly mounted on the internal ribs of the main body (110), thereby improving assembly performance and assembly speed, reducing connecting parts, and enhancing durability. In addition, compared with traditional multi-piece or split-structure PCBs, the integrated design simplifies the manufacturing process and reduces costs.
[0037] The vibration motor (130) is attached to the PCB (120) by welding and is directly mounted on the internal ribs of the body (110). This structure reduces the number of vibrating parts, reduces noise, and improves vibration stability, thereby enhancing user convenience and durability. In addition, the vibration motor (130) provides a vibration function for the toothbrush, enabling it to function as an electric toothbrush.
[0038] The bristle plate (140) is located above the light source part (122) in the brush head area of the PCB (120) and is provided with at least one waveguide-formed bristle (141). The bristles may be made of optical fibers and used to transmit light emitted by the light source to the user's teeth. In addition, the massage bristles (142) may also be made of optical fibers and can transmit light to the user's gums, oral cavity walls or tongue to provide a massage effect.
[0039] The light source unit (122) includes a first light source (122a) emitting short-wavelength light and a second light source (122b) emitting long-wavelength light. The light sources may be arranged in an alternating structure so that the light intensity is enhanced by superposition of light. Short-wavelength light (e.g., blue light) is used for sterilization or teeth whitening, while long-wavelength light (e.g., red light) has anti-inflammatory and collagen production-promoting effects.
[0040] Industrial Availability
[0041] As described above, according to one embodiment of the present invention, a light irradiation sanitation device with a PCB (printed circuit board) directly mounted on the body includes: a body forming the outer appearance of the handle and the brush head; a PCB designed and arranged inside the body according to the shape of the body, which forms a power button in the handle area, and a light source part that emits light through a waveguide in the brush head area and includes multiple light sources; a vibration motor arranged in the upper end area of the handle of the body and attached to the PCB by welding; and a bristle plate located above the light source part in the brush head area of the PCB and assembled and fixed, which includes at least one bristle formed by a waveguide. By directly mounting the PCB with the vibration motor on the rib (Rib) inside the body, noise can be reduced and noise reduction can be achieved by improving vibration stability, while enhancing convenience of use.
[0042] In addition, by changing the traditional multiple PCBs or split structures to an integrated design and by directly mounting the PCB on the internal ribs of the main body, not only the cost of components is reduced and cost competitiveness is improved, but also assembly and assembly speed are improved. At the same time, by directly mounting on the outer shape, connecting parts are removed, thereby minimizing the cause of failure and improving durability.
[0043] In particular, by installing the vibration motor on the PCB and designing the PCB to be in direct contact with the outer shape of the main body, the number of components caused by vibration can be reduced, thereby reducing noise. At the same time, the manufacturing process is simplified, achieving cost reduction and improved production efficiency.
