Description

Technical Field

[0001] This utility model relates to the field of demonstration teaching aids technology, and in particular to a demonstration teaching aid that uses environmentally friendly materials to purify water. Background Technology

[0002] Water purification demonstration kits are tools or equipment used for educational and teaching purposes, designed to demonstrate the principles, processes, and methods of water purification. Purified water refers to water that has been treated or filtered to remove impurities, harmful substances, and pollutants, thus becoming clear, clean, and suitable for human drinking, use, or irrigation.

[0003] However, most traditional water purification demonstration kits usually require the purchase of specialized materials and equipment to conduct water purification demonstrations and teaching, which increases costs. In addition, most traditional water purification demonstration kits involve complex operation and maintenance, requiring additional technical support, and are not suitable for simple educational demonstrations.

[0004] Therefore, those skilled in the art have provided a demonstration teaching aid that uses environmentally friendly materials to purify water, in order to solve the problems mentioned in the background art. Utility Model Content

Compared to most traditional water purification demonstration tools, this tool features a bottle neck connector and a filter cartridge. Users can select a plastic bottle of suitable size with a standard neck, remove the bottom, and place it on the bottle neck connector. Common filter materials such as activated carbon, gravel, and sand are then placed inside the filter cartridge to assemble the water purification demonstration tool. This tool uses inexpensive or waste materials such as recycled plastic bottles, sand, and activated carbon, making it inexpensive and suitable for use in schools and community education. Its simple structure also makes it easy to demonstrate in the classroom, thereby improving the ease of use and applicability of the water purification demonstration tool.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0012] Furthermore, two limiting rings are fixedly connected to the middle of the outer wall of the front end of the support plate, and limiting strips are fixedly connected to the inner walls on both sides of the slide groove;

[0013] The above technical solution can limit and protect the position of the plastic bottle.

[0014] Furthermore, the mounting slots are respectively opened in the middle of the upper surface of the placement platform, and the main base is fixedly connected to the inner wall of the mounting slot;

[0015] The above technical solution allows users to disassemble and replace the main base, thereby enabling them to adjust the number of water purification demonstration units according to their needs.

[0016] Furthermore, the first line interface is fixedly connected to the rear end of the upper surface of the placement platform, and the rear end of the outer wall of the main base away from the auxiliary base is fixedly connected to the second line interface.

[0017] The above technical solution enables the control button to operate the corresponding water pump.

[0018] Furthermore, a conveying groove is provided on the inner bottom surface of the bottle neck connector, and the end of the conveying groove away from the bottle neck connector is connected to the mounting threaded block;

[0019] The above technical solution enables the liquid inside the plastic bottle to be transported into the filter cartridge.

[0020] Furthermore, a sealing gasket is tightly fitted to the lower surface of the filter cylinder, and a metal bottom mesh is fixedly connected to the lower end of the inner wall of the filter cylinder.

[0021] The above technical solution improves the sealing between the filter cartridge and the mounting threaded block, and the metal bottom mesh is used to hold cotton or gauze to reduce the shedding of filter material.

[0022] Furthermore, the end of the first delivery hose away from the connecting cover is fixedly connected to the input end of the water pump, and the first snap-fit ​​connector and the second snap-fit ​​connector engage in a snap-fit ​​relationship.
