Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly daily necessities technology, and in particular to a paper usage monitoring device with visual feedback. Background Technology

[0002] With the increasing severity of global environmental pollution, people's awareness of environmental protection is growing, and more and more people want to participate in environmental protection activities. However, some existing environmental protection activities have shortcomings. For example, afforestation is time-consuming, and daily behaviors such as saving electricity lack timely positive feedback, making it difficult for people to intuitively feel their environmental contributions. Therefore, this utility model proposes a paper usage monitoring device with visual feedback. It intuitively monitors the amount of paper used through infrared sensing and converts the amount of paper used into carbon emissions and the number of trees felled. This provides users with an intuitive and timely feedback-based way to participate in environmental protection, advocating for paper conservation and increasing users' enthusiasm for environmental participation. Utility Model Content

[0003] The present invention aims to provide a paper usage monitoring device with visual feedback to solve the problem of the lack of timely positive feedback in the environmental protection of existing paper usage devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A paper usage monitoring device with visual feedback includes a housing, a computing module, a display screen, a power module, and an infrared sensing module. The housing has a paper dispenser slot on top and a tissue storage box inside, with an opening at the top. The paper dispenser slot and the tissue storage box slot's opening are aligned. A base plate is detachably connected to the bottom of the housing. The infrared sensing module includes an infrared transmitter and an infrared receiver, positioned on opposite sides inside the paper dispenser slot. The computing module is located inside the housing and connected to the infrared sensing module and the display screen via ribbon cables. The computing module receives signals from the infrared sensing module and calculates paper usage, carbon emissions, and the equivalent number of trees felled according to a preset algorithm. The power module is located inside the housing and supplies power to the device's electrical components. A temperature and humidity sensor is connected to the outside of the housing to measure temperature and humidity. The display screen is located on the outside of the housing and displays real-time data on paper usage, carbon emissions, equivalent tree felling, real-time temperature, and real-time humidity.

[0006] Furthermore, the computing module is an integrated microcontroller from the STM32 series.

[0007] Furthermore, the power module is a 2000mAh rechargeable lithium battery that is charged via a USB interface.

[0008] Furthermore, heat dissipation holes are provided on both sides of the outer casing.

[0009] Furthermore, the display is a 1.8-inch LCD screen with a scratch-resistant acrylic panel covering its surface.

[0010] Furthermore, a cover plate is rotatably connected to the top of the outer casing.

[0011] The principle and beneficial effects of this technical solution: The bottom of the outer casing of this utility model is detachably connected to a base plate. After removing the base plate, the tissue storage box can be placed inside the outer casing. Infrared sensing modules are installed on both sides inside the tissue dispenser. When a user draws tissues, the infrared sensing modules detect the tissue-drawing action and trigger a signal transmitted to the calculation module. The calculation module calculates the real-time paper consumption, carbon emissions, and equivalent tree felling, and displays this data on the display screen. Simultaneously, the real-time temperature and humidity measured by the temperature and humidity tester are also displayed on the screen. By displaying the real-time paper consumption, carbon emissions, and equivalent tree felling, users can intuitively observe the consumption of paper, which reminds them to save paper. Users' paper-saving behavior receives timely feedback, which can motivate users' environmental protection efforts. Attached Figure Description

A tissue storage box 6 is placed inside the housing 1, with an opening at the top that aligns with the tissue dispenser 11. A base plate 12 is detachably connected to the bottom of the housing 1 via a snap-fit ​​mechanism. Ventilation holes 13 are provided on the left and right sides of the housing 1. An infrared sensing module 5 is installed inside the tissue dispenser 11, and the infrared sensing module 5 includes an infrared emitter 5. Infrared transmitter 51 and infrared receiver 52 are respectively located on the left and right sides inside the tissue dispenser 11. A display screen 3 is connected to the front of the housing 1. The display screen 3 is a 1.8-inch LCD screen covered with a scratch-resistant acrylic panel. Behind the display screen 3, inside the housing 1, are a power module 4 and a computing module 2. The power module 4 is a 2000mAh rechargeable lithium battery, which is charged via a USB interface 41. The computing module 2 is an STM32 series integrated microcontroller, which is connected to the infrared sensing module 5 and the display screen 3 via an FPC flexible cable. A temperature and humidity tester 7 is connected to the rear of the housing, measuring real-time temperature and humidity and displaying them on the display screen 3.
