Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to an ultraviolet sterilization comb. Background Art

[0002] With people's increasing emphasis on personal hygiene and aesthetics, the issue of fungal hair infections has gradually come into the public eye. In daily life, an unbalanced scalp environment, inadequate cleansing, or prolonged exposure to moisture can easily create a breeding ground for fungi. These fungi not only cause embarrassing scalp odor but can also pose a serious threat to hair quality and scalp health. The risk of fungal hair infections is particularly increased for those who frequently wear tight hats, use non-breathable hair accessories, or frequently dye or perm their hair. The prolonged confinement and humidity of the scalp creates favorable conditions for fungal growth. Once fungal growth becomes widespread, it can not only cause unbearable itching and increased dandruff, but can also lead to dry, brittle hair. In severe cases, it can also cause scalp inflammation and hair loss, severely impacting personal appearance and quality of life. Therefore, keeping the scalp clean and dry and taking regular preventive measures are crucial to preventing fungal hair infections.

[0003] To address these issues, researchers have recently developed a method for using ultraviolet light from a UV disinfectant comb to sterilize and reduce inflammation in the hair. However, while this method is novel and holds great potential, it also comes with significant limitations and challenges, specifically:

[0004] First, the bactericidal effect of ultraviolet rays is highly dependent on the range and intensity of their direct irradiation. Although the original design of the UV disinfection comb is for deep cleaning and disinfection, in actual application it is often only effective for sterilizing the hair that the comb is in close contact with. As for the deep tissues of the scalp, its sterilization effect is greatly reduced, and it is difficult to ensure full coverage. In addition, the cleanliness of the surface of the UV disinfection comb is also a key factor affecting the penetration of ultraviolet rays and the bactericidal effect. If the surface of the comb is contaminated with dust, dandruff and other obstructions, the penetration of ultraviolet rays will be seriously hindered, thereby reducing the overall bactericidal efficiency. What is more vigilant is that ultraviolet rays have potential harm to the human body, especially the eyes. When using a UV disinfection comb, if the operation is not careful and the ultraviolet rays are directly exposed to the eyes, it may cause eye discomfort, inflammation or even more serious health problems, posing a potential threat to the user's health.

DETAILED DESCRIPTION

[0026] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] like Figures 1 to 5 As shown, the ultraviolet sterilization comb provided by the utility model includes a handle 1, which is a hollow structure. One end of the handle 1 is fixedly connected to a bottom shell 2 with an open top surface, and a power cable 3 is plugged into the other end of the handle 1. A brushless motor is fixedly connected to the inside of the handle 1, and a mesh air inlet 9 is provided on the bottom surface of the handle 1. The top surface of the bottom shell 2 is fixedly connected to the top shell 4, and a plurality of comb teeth 5 are fixedly connected to the bottom surface of the bottom shell 2. An indicator light 6 and a power switch 7 are installed on the side of the inner cavity of the bottom shell 2 close to the handle 1, and the indicator light 6 and the power switch 7 are exposed from the top shell 4. A control circuit board 8 is installed in the middle of the inner cavity of the bottom shell 2, and a UVC lamp bead circuit board is installed below the control circuit board 8. A plurality of UVC lamp beads are installed on the UVC lamp bead circuit board. There are several light emitting holes 10, and the positions of the light emitting holes 10 correspond one-to-one to the positions of the UVC lamp beads. Several air outlet holes 11 are opened on the bottom shell 2, and several air inlet holes 15 are opened on the control circuit board 8. The positions of the air inlet holes 15 and the air outlet holes 11 correspond one-to-one. A pressure sensing module 12 is installed between the control circuit board 8 and the indicator light 6 in the inner cavity of the bottom shell 2, and a vibration motor 13 is installed on the side of the inner cavity of the bottom shell 2 away from the pressure sensing module 12. A battery 14 is installed in the inner cavity of the bottom shell 2 near the control circuit board 8. The brushless motor, indicator light 6, power switch 7, pressure sensing module 12, vibration motor 13 and battery 14 are all electrically connected to the control circuit board 8, and the battery 14 is also electrically connected to the brushless motor.

[0028] Among them, the handle 1 and the bottom shell 2 can adopt an integrated structure to increase the stability of the overall structure. A slot for the brushless motor can be preset inside the handle 1, and the brushless motor is snapped into the slot for fixation. The top shell 4 and the bottom shell 2 can be connected by bolts. The control circuit board 8 can be fixed in the inner cavity of the bottom shell 2 through the slot, or it can be fixed by bolts. The UVC lamp bead circuit board and the control circuit board 8 can be fixed by bolts, or they can be snap-fixed. The vibration motor 13, the battery 14, and the pressure sensing module 12 can be fixed in the inner cavity of the bottom shell 2 through the slot, or they can be fixed by bolts.

[0029] When using the present invention, first plug the power cable 3 into a 220V AC power source, turn on the power switch 7, and the indicator light 6 will light up red, indicating that the UV sterilization comb is ready for operation. Next, gently place the UV sterilization comb on top of your head, allowing the comb teeth 5 to contact your hair. At this time, the pressure sensing module 12 built into the UV sterilization comb senses the pressure, and the control circuit board 8 activates the brushless motor, vibration motor 13, and UVC lamp beads, at which point the indicator light 6 turns green. As the brushless motor starts, a strong airflow is drawn in through the mesh air inlet 9 and blown out through the air outlet 11 of the bottom shell 2. Under the influence of the wind, the hair naturally tilts to the sides, exposing the scalp and hair roots. This arrangement allows the UVC lamp beads to directly illuminate the scalp surface, effectively killing bacteria and microorganisms and achieving a sterilizing effect. At the same time, the wind force generated by the brushless motor can also help remove dust, dandruff, and other dirt in front of the UVC lamp beads, ensuring a more comprehensive irradiation effect. In addition to its sterilizing function, the air blown by the brushless motor can also dry the surface of the hair and scalp, thereby reducing the risk of bacteria breeding in a humid environment. The vibration motor 13 can massage the scalp, helping to relieve scalp tension and promote blood circulation.

[0030] When the UV comb is removed from the hair, the pressure sensing module 12 senses no pressure, and the control circuit board 8 immediately stops the brushless motor, vibration motor 13, and UVC lamps to prevent accidental eye damage or other unnecessary harm from UV rays. Furthermore, the control circuit board 8 can also preset a one-minute operating time. If the UV comb remains in operation for one minute and remains in place, the control circuit board 8 will automatically stop the brushless motor, vibration motor 13, and UVC lamps to prevent potential risks from prolonged exposure to the skin.

[0031] In a specific embodiment, Figure 6 As shown, the control circuit board 8 includes a control unit 81, an AC-DC unit 82 and a battery management unit 83. The plug-in cable 3 is connected to the power input end of the AC-DC unit 82, the power output end of the AC-DC unit 82 is connected to the power input end of the control unit 81, the power output end of the control unit 81 is connected to the brushless motor, the signal output end of the pressure sensing module 12 is connected to the signal input end of the control unit 81, the signal output end of the control unit 81 is connected to the brushless motor, the indicator light 6, the UVC lamp bead circuit board and the vibration motor 13, the battery management unit 83 is connected between the control unit 81 and the battery 14, and the power switch 7 is also connected to the signal input end of the control unit 81.

[0032] Specifically, when the power switch 7 is triggered, the AC-DC unit 82 converts 220V AC power to the voltage required by the control unit 81 and the brushless motor, powering them. When the pressure sensing module 12 senses a pressure signal, the control unit 81 controls the brushless motor, indicator light 6, UVC lamp circuit board, and vibration motor 13. Simultaneously, the control unit 81 controls the battery management unit 83 to manage the charging and discharging of the battery 14, ensuring that the battery 14 charges when it is low on power and stops charging when it is fully charged.

[0033] In a specific embodiment, the number of the air inlet holes 15 is five, the first air inlet hole 15 is located in the middle of the control circuit board 8, and the other four air inlet holes 15 are located around the first air inlet hole 15, and the line connecting the centers of the other four air inlet holes 15 is a square; the number of UVC lamp beads on the UVC lamp bead circuit board is four, and the line connecting the centers of the four UVC lamp beads is a square; an air inlet hole is opened in the middle of the UVC lamp bead circuit board, and the air inlet hole corresponds to the position of the first air inlet hole 15. By arranging the positions of the air inlet holes 15 and the air outlet holes 10 in this way, it is ensured that multi-directional air intake and outlet can be achieved, ensuring that a relatively large amount of air reaches the scalp. Figure 7 As shown, it is a simulated luminous diagram of the UVC lamp beads in the UVC lamp bead circuit board. By arranging the UVC lamp beads in this way, it is ensured that ultraviolet sterilization can be carried out simultaneously through multiple UVC lamp beads, thereby improving the sterilization efficiency and ensuring that the ultraviolet irradiation is relatively uniform.

[0034] In a specific embodiment, a filter is installed at the mesh air inlet 9. The filter can filter out impurities in the air entering the handle 1 and the bottom shell 2, preventing these impurities from affecting the use of the components inside the bottom shell 2.

[0035] In a specific embodiment, a plurality of comb teeth 5 are evenly distributed on the bottom surface of the bottom shell 2 to ensure that all parts of the head are combed evenly when combing the hair.

[0036] In a specific embodiment, the length of the comb teeth 5 is 2 cm. In this configuration, when the UVC germicidal comb is placed against the scalp, the UVC lamp beads are about 2.2 cm away from the scalp surface (the UVC lamp beads are about 0.2 cm away from the bottom surface of the bottom shell 2. At this distance, the UVC lamp beads can produce 35200 μW / cm 2 The ultraviolet radiation intensity can quickly kill the fungi on the surface of hair and scalp within 1 minute.

[0037] In a specific embodiment, the UVC lamp beads use ultraviolet lamp beads with a wavelength of 275-280nm and a light-emitting angle of 60°. This type of UVC lamp beads can irradiate a 60° fan-shaped area on the scalp surface, thereby improving the sterilization efficiency.

[0038] In one specific embodiment, the pressure sensing module 12 can be a pressure sensor. The brushless motor can be a 7.4V input motor with a diameter of 28.8mm, a length of 40mm, and a weight of only 62g, equivalent to the weight of 10 coins. However, it rotates 130,000 times per minute, generating a wind speed of up to 28m / s and a wind pressure of up to 180g. This wind force is comparable to that generated by a traditional hair dryer. Under this wind force, for most patients requiring this type of treatment, this motor can expose a large portion of the scalp, thereby achieving a deep sterilization effect.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
