Description

Technical Field

[0001] This utility model relates to the field of ear-cleaning equipment technology, and in particular, to an ear-cleaning lamp with a display screen. Background Technology

[0002] Ear cleaning refers to the process by which an ear cleaner uses specialized tools to remove earwax and foreign objects from the ear canal in order to keep the ear canal clean and hygienic. Because the human ear canal is relatively deep and narrow, and is quite sensitive and easily injured, ear cleaners must use lighting to see the inside of the ear canal clearly during the ear cleaning operation in order to avoid irritating the ear canal or even causing injury during the operation.

[0003] Currently, ear-cleaning lights generally come in two types: thumb lights and hand lights. Thumb lights are lamps that attach to the ear-cleaning practitioner's thumb via a finger clip, allowing the lighting angle to be adjusted as the thumb moves; they are relatively small and flexible. Hand lights, on the other hand, are handheld lamps that provide illumination by being held in the hand. Compared to regular flashlights, they need to have a lighter and more compact structure to allow the ear-cleaning practitioner to hold them comfortably for delicate ear-cleaning procedures. Therefore, both types of ear-cleaning lights are limited by their size, resulting in insufficient battery life and requiring frequent battery replacements, making them inconvenient to use.

[0004] In response, Chinese utility model patent CN211083668U provides a rechargeable ear-cleaning lamp that uses a rechargeable battery for continuous charging, allowing for cyclic charging and continuous illumination, thus enhancing the lamp's safety and durability. However, while the rechargeable battery allows the lamp to be charged, it doesn't always detect low battery levels promptly. Users often only remember to recharge when the battery is completely depleted, inevitably disrupting ear-cleaning operations and necessitating the use of multiple lamps. Furthermore, using the lamp with low battery results in insufficient brightness, failing to adequately illuminate the ear canal and affecting the effectiveness of the treatment.

[0046] The ear-cleaning lamp with a display screen provided by this utility model has a display screen 21 on the circuit board 2, and a light-transmitting protective cover 3 is provided on the first mounting window 11 of the housing 1 to allow the display content of the display screen 21 to be displayed outwards. Thus, the display screen 21 can display conventional information such as remaining battery power, lighting level, lighting duration, and remaining lighting duration in real time (see reference). Figure 5 This design allows users to easily monitor relevant parameters each time they use the device, promptly identifying low battery levels and enabling timely charging or battery replacement during downtime. This prevents sudden power outages that could disrupt ear-cleaning operations and avoid insufficient brightness affecting lighting performance. Furthermore, since the display screen 21 is directly integrated into the circuit board 2, it can utilize a digital tube or a non-touchscreen LCD screen. Protected by the light-transmitting cover 3, the structure is simple, compact, and low-cost. No wiring is required; the display screen 21 is installed simply by snapping the circuit board 2 into the housing 1, facilitating assembly. The light-transmitting cover 3 also uses a snap-fit ​​structure for easy assembly and replacement.

[0047] Furthermore, the light-transmitting protective cover 3 is made of a dark-colored light-transmitting material, so that the internal structure of the receiving cavity cannot be seen through the light-transmitting protective cover 3 when the display screen 21 is off, but the display content of the display screen 21 can be seen through the light-transmitting protective cover 3 when the display screen 21 is on, which is suitable for digital tube displays. In other embodiments, when the display screen 21 is a liquid crystal display, the light-transmitting protective cover 3 can also be made of a light-colored semi-transparent material or a transparent material to improve light transmittance and enhance the display effect of the display screen 21.
