Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of oral hygiene, and in particular to a blue light toothbrush. Background Technology
[0002] Toothbrushes, as one of the most commonly used tools for oral hygiene, are used to clean teeth and gums. Specifically, the bristles on the toothbrush head rub against the tooth surface to remove stains and clean the teeth. However, simply using a toothbrush for oral cleaning seems insufficient, and if teeth are not brushed regularly, bacteria can easily grow in the mouth, affecting oral hygiene. Currently, there are luminous toothbrushes on the market, such as the Chinese utility model patent for a light-emitting diode toothbrush device with publication number CN2792296Y. These toothbrushes use light waves emitted by the toothbrush to illuminate the mouth and improve the cleaning effect. However, this luminous toothbrush uses a button to control the light emission, requiring users to manually press the button to turn it on or off each time, which is extremely inconvenient. Moreover, the button is prone to damage over time, thus affecting the lifespan of the luminous toothbrush. Utility Model Content
[0003] The technical problem to be solved by this utility model embodiment is to provide a blue light toothbrush that automatically triggers the brush head to emit blue light by touch or shaking, making it more convenient for users.
[0004] To achieve the above objectives, this utility model discloses a blue light toothbrush, including a toothbrush body. The brush head of the toothbrush body has several bundles of bristles. A light-emitting component is disposed within the brush head. The light-emitting component includes a light-emitting element, a switch triggering unit, and a circuit board. The circuit board is disposed within the brush head. The light-emitting element and the switch triggering unit are electrically connected and disposed on the circuit board, with the light-emitting element facing the bristles. A power supply unit is disposed within the toothbrush body and electrically connected to the circuit board, so that the switch triggering unit controls the light-emitting element to turn on, causing the light-emitting element to project light waves towards the bristles for inhibiting some bacteria in the oral cavity or on the bristles.
[0005] Furthermore, the switch triggering unit includes either a touch switch or a vibration switch.
[0006] Furthermore, the triggering method of the switch triggering unit includes either touch or shaking.
[0007] Furthermore, the light-emitting component also includes a timing module, which is electrically connected to the circuit board.
[0008] By using the aforementioned touch, press, or vibration methods to trigger the light-emitting element, the number of holes is reduced compared to the traditional button method, effectively improving the sealing of the toothbrush's interior.
[0009] Furthermore, the toothbrush body includes an integrally formed brush head and a brush handle. The brush head has a hollow cavity, and a bristle substrate is embedded in the front of the cavity. The several bundles of bristles are evenly distributed on the bristle substrate.
[0010] Furthermore, the back of the brush handle is provided with a recess that communicates with the cavity, the power supply unit is disposed in the recess and is electrically connected to the circuit board via a cable or flexible flat cable, and the toothbrush body is covered with a cover plate that matches the shape of the cavity and the recess.
[0011] Furthermore, the power supply unit includes a trigger control circuit board and a battery. The trigger control circuit board and the battery are disposed in the cavity, and the battery is electrically connected to the trigger control circuit board. The trigger control circuit board is electrically connected to the circuit board substrate and is used to receive the trigger signal from the switch trigger unit to control the working state of the light-emitting component.
[0012] Furthermore, the several bundles of bristles and the bristle substrate are made of transparent or semi-transparent materials, thereby increasing the light transmittance of the bristles and the bristle substrate, so that the light waves projected by the light-emitting element can better illuminate the oral cavity.
[0013] Furthermore, the light-emitting element is a blue LED lamp, and the wavelength of the light-emitting element is 400nm-410nm.
[0014] Furthermore, the outer peripheral surface of the toothbrush body is coated with a colloid to improve the overall sealing of the toothbrush.
[0015] Furthermore, the brush substrate is provided with a plurality of positioning posts, and the circuit board is provided with a plurality of positioning holes that cooperate with the positioning posts.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] (1) In this utility model, a switch triggering unit is provided on the circuit board. The light-emitting component is activated by touch or shaking instead of the traditional button method. This not only makes it more convenient to use, but also reduces the number of buttons, resulting in better sealing inside the toothbrush. Furthermore, the blue light can inhibit some bacteria in the oral cavity. (2) The surface of the toothbrush is covered with a colloid, which prevents the light-emitting component and power module inside the toothbrush from coming into contact with water, avoiding short circuits and greatly improving the service life of the toothbrush.

[0022] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.
[0023] Reference Figure 1 , Figure 2 As shown, a blue light toothbrush includes a toothbrush body 1, a brush head 11 of the toothbrush body 1 with a plurality of bristles 13 on the front side, a light-emitting component 2 is disposed inside the brush head 11 of the toothbrush body 1, and a power supply unit 3 is disposed inside the toothbrush body 1 and electrically connected to the light-emitting component 2 to provide power to the light-emitting component 2.
[0024] Specifically, the toothbrush body 1 includes an integrally formed brush head 11 and a brush handle 12. The brush head 11 has a hollow cavity 111. A bristle substrate 14 is embedded in the front of the cavity 111. Several bundles of bristles 13 are evenly distributed on the bristle substrate 14. In this embodiment, the bundles of bristles 13 and the bristle substrate 14 are made of transparent or semi-transparent materials. The bristles are preferably made of transparent materials such as PBT or transparent nylon, and the bristle substrate 14 is preferably made of transparent plastics such as PMMA, ABS, PC, PETG, or PP, thereby increasing the light transmittance so that the light waves emitted by the light-emitting component 2 can penetrate the bristle substrate and the bristles to irradiate the teeth or gums.
[0025] Reference Figure 2 , Figure 3As shown, the light-emitting component 2 further includes a plurality of light-emitting elements 21, a switch triggering unit 22, and a circuit board 23. The plurality of light-emitting elements 21, the switch triggering unit 22, and the circuit board 23 are electrically connected. In this embodiment, the light-emitting elements 21 are preferably blue LEDs with a wavelength of 400nm-410nm. In this embodiment, the wavelength of the light-emitting elements 21 is preferably 405nm. The switch triggering unit 22 is electrically connected to the circuit board 23. In this embodiment, a plurality of positioning posts 141 are provided on the brush substrate 14, and a plurality of positioning posts 141 are provided on the circuit board 23. There are several positioning holes 231 that mate with the positioning posts 141, so that the circuit board 23 is placed inside the brush head 11, and several light-emitting elements 21 are facing the direction of the bristles 13. The back of the brush handle 12 is provided with a cavity 121 that communicates with the cavity 111. The power supply unit 3 is disposed in the cavity 121 and is electrically connected to the circuit board 23 through a cable or flexible flat cable. The toothbrush body 1 is covered with a cover plate 15 that matches the shape of the cavity 111 and the cavity 121, and the switch trigger unit 22 abuts against the cover plate 15.
[0026] Furthermore, the power supply unit 3 includes a battery 32 disposed in the cavity 121, and the battery 32 is electrically connected to the circuit board 23 via a cable. The switch triggering unit 22 includes either a touch switch or a vibration switch.
[0027] In this embodiment, the touch switch can be any one of a capacitive touch sensor, an infrared touch sensor, or a pressure-sensitive touch sensor. A capacitive touch sensor is preferred in this embodiment, while a vibration sensor is preferred for the vibration switch. Therefore, when the back of the brush head is touched or shaken, the switch trigger unit 22 generates a trigger signal to activate the battery and provide power to the light-emitting component 2, so that several light-emitting elements 21 project 405nm blue light onto the brush head 13.
[0028] In another embodiment, the touch switch in this embodiment can also be a resistive touch sensor. By designing the cover plate as a soft material, the switch trigger unit generates a trigger signal by pressing the back of the brush head.
[0029] Therefore, during brushing, the 405nm blue light generated by the brush head shines on the teeth and gums. This 405nm blue light can be absorbed by endogenous porphyrins in cells, which can inhibit or eliminate Porphyromonas gingivalis and other bacteria that cause periodontitis, thus better maintaining oral health.
[0030] In this embodiment, the light-emitting component 2 also includes a timing module. The timing module is electrically connected to the circuit board 23. The timing module preferably uses an STM32 timer to control the irradiation duration of the light-emitting component 21. For example, the light-emitting component 21 is set to turn off after 10 minutes after being turned on. Therefore, after the user finishes brushing his teeth, he uses the 405nm blue light emitted by the light-emitting component 21 to irradiate the bristles on the brush head, thereby reducing some bacteria on the surface of the bristles.
[0031] In another embodiment, the power supply unit 3 further includes a trigger control circuit board 31, which is disposed in the cavity 111. A pair of insert rods are disposed in the cavity 111. The trigger control circuit board 31 has insertion holes at both ends that cooperate with the insert rods, so that the trigger control circuit board 31 is not displaced after being disposed in the cavity. The trigger control circuit board 31 is electrically connected to the battery through a cable, and the trigger control circuit board 31 is electrically connected through a cable or a flexible flat cable, thereby receiving the trigger signal from the switch trigger unit to control the working state of the light-emitting component 2.
[0032] Specifically, when using the toothbrush, the user touches or shakes the brush head, causing the switch trigger unit 22 to generate a trigger signal and feed it back to the trigger control unit 31. The trigger control unit 31 then controls the battery to start, so that the battery provides power to several light-emitting elements 21, thereby causing the several light-emitting elements 21 to emit 405nm blue light to the bristles 13, thereby using the blue light to inhibit some bacteria.
[0033] Reference Figure 4 As shown, in this embodiment, the outer peripheral surface of the toothbrush body 1 is coated with a colloid, which greatly improves the sealing of the toothbrush body 1 and prevents the light-emitting component 2 and the power supply unit 3 from coming into contact with water during brushing, thus avoiding a short circuit.
[0034] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They cannot be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit of the main technical solution of this utility model should be covered within the protection scope of this utility model.
