Preface:

In today's society, where children's education is increasingly valued, scientific enlightenment education has gradually become an important topic in the field of education, which is pursued and explored. More and more teachers and parents are beginning to pay attention to cultivating children's scientific literacy from an early age, so that children can develop good personalities and behavioral habits from the beginning. Parent-child interactive crafts can improve the quality of parent-child companionship, improve the relationship between parents and children, and we spend time with our children, without mobile phones, iPads, or televisions, only joy, interaction, and communication. It can cultivate the ability of children to solve problems by themselves. When children encounter problems, they should first see and experience the solution themselves, because parents and teachers solve problems in the process of doing crafts. It can develop children's imagination. In children's world, cars can fly in the sky, and the sun can be green. Playing with DIY crafts can cultivate children's practical ability by using different tools, which fully exercises children's little hands. Brushes, paints, scissors, hot-melt guns, glue"Children are brave to try any tools and to some extent, they are developing different skills. Improving children's self-confidence in the process of handcrafts, we try everything possible together, experience many failures, but we always succeed, which to some extent enhances their self-confidence. Cultivating children's concentration when children explore various tools and handcrafts, they are very focused, and if there is no external disturbance, they can continue to explore.

The purpose of the experiment: To enable children to learn more about scientific knowledge and their own ability to practice by means of game entertainment.

Principle of Application: The motor of the vacuum cleaner rotates at high speed, sucks air into the suction inlet, creating a certain vacuum in the dust box, and the dust enters the dust bag in the dust box through the suction pipe. The dust is left in the dust bag, and the air after filtering passes through another layer of filter before entering the motor and then exiting.

Experimental Cognition: The basic structure of a vacuum cleaner is divided into power, filtration system, and functional parts based on function.

Knowledge Expansion: The Components of Vacuum Cleaners: Most vacuum cleaners are equipped with a assembly brush head, which is used for cleaning floors and carpets. Suction-type vacuum cleaners also come with a variety of cleaning brushes and nozzles, allowing for the cleaning of corners, curtains, sofas, and gaps.

Knowledge Extension: A vacuum cleaner is mainly composed of three parts: dust collection, suction, and filtration. It typically includes a series-excited commutator motor, a centrifugal fan, a dust filter (bag), and suction attachments. The power of a typical vacuum cleaner ranges from 400-1000W or higher, while that of a portable vacuum cleaner is usually 250W or less. The main reason a vacuum cleaner can remove dust is due to its "head" equipped with an electrically driven blower. The blower's shaft has a fan blade, which, when powered, spins at a rate of 500 revolutions per second to generate a high suction and pressure. Under the influence of suction and pressure, air is rapidly discharged, and the air in the front of the blower is continuously replenished by the air in the blower, causing a temporary vacuum in the vacuum cleaner. This vacuum is created by the pressure difference between the vacuum cleaner and the surrounding atmosphere, allowing it to suck in air containing dust. Dust and other contaminants are then sequentially drawn through the carpet or floor brush, the long extension, the bend, the hose, the hose connector, and into the dust filter bag.

Safety Warning:

All the accessories in this product are specially designed for student experiments. Please use them under the supervision of teachers and parents to ensure safety! Do not consume any of the products! They are not suitable for children under three years of age. Do not approach fire sources. Before assembling any batteries, please check if the circuit is clear, all parts of the circuit are complete, and all contacts are good. The + on the battery is the positive pole, and - is the negative pole. Be careful during the assembly process, and if glue is used, do not get it in your eyes or on your skin.
