How to make a small fan that spins without electricity?

Use four magnets, one on each side. (Ask for a desktop radiator) and then take a piece of black tape and glue it well. That's it.

Fans are sold in electronics city, or computer repair shops are also available.

How to cool off the summer is a topic that must be discussed every summer, air conditioning sister meow has taken everyone to the group many times, easy to use, but in the early summer and late summer, the temperature is not high This time period is a little embarrassing, and blowing the air conditioner for a long time will also bring fatigue, headaches and other "air conditioning diseases". Sister Meow suggested that air conditioning + fan is the best combination for cooling summer.

This time** brings you two Kosi fans. Source: Kosi friends who pursue cost-effectiveness can choose a desktop moving head fan, a double-layer 21-blade seagull fan can create a more comfortable and wide "green wind", that is, you can feel the soft wind caressing your skin, but you can't tell where the wind comes from.

Source: Kexi intelligent temperature inverter function, can intelligently change the wind speed according to room temperature, will not catch a cold and save more power at the same time, according to 90 days, 10 hours a day of use, using the frequency conversion mode only needs 5 kilowatt-hours of electricity in a summer. The most attractive thing about Sister Meow is that this fan also has a negative ion function, while blowing the air.

It can eliminate soot, reduce the content in the air, and accelerate the reduction of formaldehyde content.

Make your own small fan that doesn't require electricity.

Principle: The energized coil rotates under force in a magnetic field. The form of energy conversion is: electrical energy is mainly converted into mechanical energy.

At the same time, because the coil has resistance, it is inevitable that some electrical energy will be converted into heat energy.

Mechanical fans first originated on the roofs of houses. In 1829, an American named James Byron was inspired by the structure of a clock and invented one that could be fixed to the ceiling.

, a mechanical fan driven by a clockwork. The cool breeze from the fan blades is pleasant, but it is a hassle to climb a ladder to get wind.

It was not until 1880 that the American Schuler first installed the blades directly on the electric motor, and then connected to the power supply, the blades rotated rapidly, and the cool breeze came to the face, which was the world's first electricity.

Common faults. 1. The fan shaft part should ensure that there is lubricating oil, otherwise the fan blade cannot be dragged by the motive on it. If you are at home, you can choose to turn off the power and then turn the fan blades, if the rotation is stiff, there is basically no lubricating oil.

2. Wear and tear caused by long-term use. If a fan is used for a long time, the motor will wear out, and the shaft sleeve of the motor will easily burn out after wearing.

The main component of the electric fan is: AC motor. Here's how it works:

The energized coil rotates by force in a magnetic field. The form of energy conversion is: electrical energy is mainly converted into mechanical energy, and at the same time, because the coil has resistance, it is inevitable that some electrical energy will be converted into thermal energy.

Summary. Dear, I'm honored to have your question The information that the teacher found for you here is: What do you gain by being a fan that can be turned without electricity?

What do you gain by making a fan that can turn without electricity: the vast majority of electric fans, are relying on the motor as a power to make the fan blades rotate and stir the air to blow cool, this kind of fan is not effective without electricity, so it can not be used in the place where there is no electricity or when the power is out, in addition, because the power generation consumes a lot of resources, makes its use cost is also relatively high, for families with lower incomes, it is more difficult to use, most of these families use hand-cranked fans to prevent heatstroke and cool down, When people are hot, they are easy to get tired after shaking the fan blades for a long time, and it will be very hot when they stop, especially when they just sleep, people are used to sleeping while fanning, and they can not use the fan after falling asleep.

Dear, I'm honored to have your question The information that the teacher found for you here is: What do you gain by being a fan that can be turned without electricity? Make a fan that can turn without electricity, what do you gain:

The vast majority of electric fans, is to rely on the motor as a power to make the fan blades turn the shed blindly stir the air to blow cool, this kind of fan does not work without electricity, so it can not be used in the place where there is no electricity or when the power is out, in addition, the chain collapse due to the power generation to consume a lot of resources, so that its use cost is also relatively high, for families with lower incomes, it is more difficult to use, most of these families use the hand fan to prevent heat stroke and cool down, when people are hot, it is easy to get tired after shaking the fan blade by hand for a long time, and it will be very hot when it stops, Especially when people just go to bed, people are used to sleeping while fanning, and after falling asleep, you can not use the windbreaker fan, in this case, people need a cheap and high-quality non-electric natural fan to solve the urgent need of blowing wind and cooling down in a not too long time.

The process of making a homemade small fan is as follows:

Material preparation: beverage bottle, small motor, knife.

Operation method: 1. Use a knife to cut the beverage bottle from the middle, evenly divide it into six parts, and mark it.

2. Use scissors to cut to the mouth of the bottle according to the made mark, and keep three copies at intervals.

3. Slowly bake the candle so that each fan blade can become straight.

4. Insert the beverage bottle cap into the small motor shaft.

5. After connecting the wire and battery, turn on the switch to make the fan rotate and the production is completed.

The production principle of the homemade electric fan:

The principle of making a homemade small fan is based on the principles of electricity and mechanics. It uses the interaction of electronic components and simple mechanical devices to achieve the effect of unbridled air flow and ventilation and cooling.

The core component of a small fan is a motor, powered by an external power supply, which generates mechanical motion and drives the blades to rotate. When an electric current is passed through the motor coil to create a magnetic field, a force is created with the magnet, which causes the motor to rotate. During the rotation process, the axis of the motor rotates, driving the blades to rotate, producing a certain wind speed and flow.

In the actual production, the designer will add fan covers, blades, power supplies and other components to achieve better results. When the motor is running, the blades generate air volume and wind force in the hood, which can form an air flow, so that the air flows through the heat sink or other items in the hood, which plays the role of cooling and ventilation chain head.

In addition, the production of small fans also needs to pay attention to electrical insulation, speed control and other issues. Reasonable design of circuit and motor parameters can maximize the efficiency of the small fan, so that it can achieve good heat dissipation and ventilation effects, and also has low energy consumption and noise.

The selection of materials should consider its thermal conductivity, electrical insulation, mechanical strength and other factors to ensure the safety and reliability of the small fan. In terms of appearance, designers need to take into account issues such as its shape and color to make it more attractive and operable, and more convenient and practical in the process of use.
