Description

Technical Field

[0001] This utility model belongs to the field of disinfection and sterilization equipment technology, specifically a non-contact, energy-saving household physical antibacterial device. Background Technology

[0002] Non-contact physical antibacterial devices typically refer to equipment that uses physical means to inhibit or kill bacteria and viruses, rather than chemical disinfectants. For example, they can use ultraviolet light in the UVC band to destroy the DNA or RNA of microorganisms, rendering them unable to reproduce and thus achieving sterilization. This disinfection method needs to be carried out in an unoccupied environment to avoid harm to the human body from ultraviolet light.

[0003] In a home environment, when using ultraviolet germicidal lamps, it is necessary to increase the intensity of ultraviolet radiation in certain areas and reduce the direct exposure of family members to ultraviolet radiation in areas with frequent human activity to reduce health risks. However, current physical antibacterial devices that use ultraviolet irradiation for sterilization cannot adjust the direction and intensity of ultraviolet radiation. Therefore, this application proposes a contactless energy-saving household physical antibacterial device. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] This specific embodiment provides a contactless, energy-saving household physical antibacterial device, such as... Figure 1-3 As shown, it includes a base and an ultraviolet lamp 1 installed on top of the base. The base includes a first sub-base 2 and a second sub-base 3 arranged sequentially from top to bottom. The ultraviolet lamp 1 is connected to the center of the top of the first sub-base 2. The ultraviolet lamp 1 is provided with a reflective mechanism around its perimeter. The reflective mechanism can reflect ultraviolet rays. A rotating mechanism is provided inside the second sub-base 3. The free end of the rotating mechanism can rotatably pass through the top wall of the second sub-base 3 and is fixedly connected to the bottom of the first sub-base 2.

[0019] The reflective mechanism includes a fixed arc plate 4 and a movable arc plate 5. The fixed arc plate 4 is fixedly installed on the top of the first sub-base 2. The top wall of the first sub-base 2 is provided with a groove 6, which matches the curvature of the movable arc plate 5. The bottom of the movable arc plate 5 is slidably connected to the groove 6. The side walls of both the fixed arc plate 4 and the movable arc plate 5 are provided with reflective films. When the ultraviolet lamp 1 is in operation, the ultraviolet rays emitted are reflected by the reflective films on the fixed arc plate 4 and the movable arc plate 5. The movable arc plate 5 is moved along the groove 6 to adjust the overall area of ​​the reflective mechanism, thereby adjusting the size of the area irradiated by ultraviolet rays and improving the effect of targeted sterilization.

[0020] The reflective mechanism also includes an arc-shaped rack 7 installed at the bottom of the movable arc plate 5 and a first drive motor 8 installed at the top of the first sub-base 2. The output end of the first drive motor 8 passes through the top wall of the first sub-base 2 and is fixedly connected to a first gear 9. The first gear 9 and the arc-shaped rack 7 are meshed together. When adjusting the movable arc plate 5, the first drive motor 8 is started to drive the first gear 9 to rotate, and then the movable arc plate 5 is moved along the slide groove 6 through the meshing arc-shaped rack 7.

[0021] The rotating mechanism includes a rotating shaft 11 and a second drive motor 10 installed inside the second sub-base 3. The bottom of the rotating shaft 11 is rotatably connected to the bottom wall of the inner cavity of the second sub-base 3, and the top is rotatably connected through the top wall of the second sub-base 3 and fixedly connected to the bottom of the first sub-base 2. A crown gear 12 is circumferentially sleeved on the rotating shaft 11. A second gear 13 is installed at the output end of the second drive motor 10. The second gear 13 and the crown gear 12 are meshed and connected. The second drive motor 10 drives the second gear 13 to rotate, which in turn drives the rotating shaft 11 to rotate through the meshing crown gear 12, thereby driving the first sub-base 2 to rotate, thus adjusting the direction of ultraviolet irradiation.

[0022] The reflective film is made of polytetrafluoroethylene (PTFE), which has a very high reflectivity and good resistance to ultraviolet light.

[0023] Working principle: In use, the first drive motor 8 is started to drive the first gear 9 to rotate, which in turn drives the movable arc plate 5 to move along the slide groove 6 through the meshing arc rack 7, adjusting the overall area of ​​the reflective mechanism. The ultraviolet rays emitted by the ultraviolet lamp 1 in the working state can be reflected by the reflective film on the fixed arc plate 4 and the movable arc plate 5, thereby adjusting the size of the ultraviolet irradiation area. By adjusting and increasing the area of ​​the reflective mechanism, the channel through which ultraviolet rays can be emitted becomes smaller, and the ultraviolet irradiation becomes more concentrated, which can increase the ultraviolet intensity per unit area. Then, the second drive motor 10 is controlled to drive the second gear 13 to rotate, which drives the rotating shaft 11 to rotate through the meshing crown gear 12, thereby driving the first sub-base 2 to rotate, thereby adjusting the direction of ultraviolet irradiation, achieving a directional sterilization effect, and blocking ultraviolet rays through the reflective mechanism to prevent ultraviolet rays from directly irradiating the human body.
