简易喷雾小风扇

步骤 1: 准备风扇叶片 (Preparing the Fan Blade)

从纽扣电池包装的塑料片上剪下一小块。用卡尺测量并确定尺寸，这里是 8.8mm。在中心钻一个小孔。 Cut a small piece from the plastic sheet of button cell packaging. Use calipers to measure and determine the size, which is 8.8mm here. Drill a small hole in the center.

步骤 2: 制作简易模具 (Making a Simple Mold)

取一小块纸板，对折后在中间挖个槽。把花生仁放入槽中。 Take a small piece of cardboard, fold it in half, and cut a groove in the middle. Place peanut kernels in the groove.

步骤 3: 制作塑料风扇叶片 (Forming the Plastic Fan Blade)

将剪好的塑料片放在花生仁上，然后用老虎钳夹紧。花生仁的形状会把塑料片压制成带有弧度的叶片。 Place the cut plastic piece over the peanuts, then clamp it tightly with the bench vise. The shape of the peanuts will press the plastic piece into curved blades.

步骤 4: 修整风扇叶片 (Trimming the Fan Blade)

取出压制好的塑料片。用美工刀小心地沿着压出的痕迹切割，形成四个独立的叶片。 Take out the pressed plastic piece. Carefully cut along the pressed lines with a utility knife to form four separate blades.

步骤 5: 固定叶片到电机轴 (Attaching Blade to Motor Shaft)

在微型电机 (#408 Motor) 的轴上滴一小滴 704 硅橡胶 (或其他胶水)。将修整好的塑料叶片（带有中心孔）固定到电机轴上，等待胶水凝固。 Put a small drop of 704 Silastic (or other adhesive) on the shaft of the miniature motor (#408 Motor). Attach the trimmed plastic blade (with the center hole) to the motor shaft and wait for the adhesive to set.

步骤 6: 制作喷雾头组件（底部）(Making the Spray Head Component - Bottom)

取 2.5ml 注射器的活塞杆。用美工刀和钢锯将其切割成图示形状的喷雾头底部，包括一个中心孔和一个侧面喷雾口。 Take the plunger rod of the 2.5ml syringe. Use a utility knife and hacksaw to cut it into the shape of the spray head bottom as shown, including a central hole and a side spray outlet.

步骤 7: 制作喷雾头组件（顶部）(Making the Spray Head Component - Top)

取 2.5ml 注射器的主体部分。用美工刀和钢锯将其切割成图示形状的喷雾头顶部，包括一个用于连接水管的侧口。 Take the main body of the 2.5ml syringe. Use a utility knife and hacksaw to cut it into the shape of the spray head top as shown, including a side port for connecting the water tube.

步骤 8: 组装喷雾头和电机 (Assembling the Spray Head and Motor)

将微型电机固定在喷雾头底部组件的中心孔上方，确保电机轴可以通过该孔。使用胶水固定。然后将喷雾头顶部组件固定在电机上方，确保侧面喷雾口与叶片旋转平面垂直。 Fix the miniature motor above the central hole of the spray head bottom component, ensuring the motor shaft can pass through the hole. Use adhesive to secure it. Then fix the spray head top component above the motor, ensuring the side spray outlet is perpendicular to the fan blade's rotation plane.

步骤 9: 连接水管和电源 (Connecting Water Tube and Power)

在喷雾头顶部的侧口连接一段软管。将软管的另一端插入装满水的塑料水瓶中。将微型电机的导线连接到电池或电池盒上。视频中使用了纽扣电池连接导线。 Connect a soft tube to the side port of the spray head top. Insert the other end of the tube into a plastic water bottle filled with water. Connect the miniature motor's wires to a battery or battery holder. The video shows connecting wires to a button cell battery.

也可以使用电池盒连接，提供更稳定的电力。 A battery holder can also be used for a more stable power source.
