1. Insulation protection: Inside small appliances, the wire connection point is an easy place for safety hazards. For example, when the heating element of an electric kettle is connected to the power cord, using heat shrink tubing over the connection point and then heating it up to make it shrink will tightly wrap around the connection point, effectively preventing the wire from shorting out. This is because the heat shrink tubing provides a reliable insulating layer that isolates the current and avoids leakage or short-circuit situations caused by exposed wires.

2. Waterproof and moisture-proof: For some small appliances that may come into contact with moisture, such as humidifiers, small car washers, etc., the waterproof performance of heat shrink tubing is particularly important. Heat shrink tubing over key wire interfaces or some components of the circuit board, even in humid environments, can prevent moisture from entering the circuit, thus protecting the normal operation of the appliance. For example, on the circuit board of a humidifier, the use of heat shrink tubing on some of the wires connected to the electronic components near the water tank can prevent damage to the components due to moisture.

3. Mechanical protection and fixation: heat shrink tubing shrinkage will fit tightly on the surface of the object being wrapped, for small appliances inside the wire, which can provide some mechanical protection. For example, inside a hand-held blender, the wires may rub against other parts due to the vibration of the machine, and the use of heat shrink tubing can minimize the damage to the wires caused by this friction. At the same time, the heat shrink tubing can also play a role in fixing the position of the wire, preventing the wire from shaking inside the equipment and reducing the failure caused by the movement of the wire.

4. Beautify the appearance and marking role: after repairing small appliances, the use of heat shrink tubing can make the repair parts look more neat and beautiful. Moreover, heat shrink tubing comes in different sizes and colors (black in this case), so you can choose the right heat shrink tubing according to the actual need to differentiate between different functional wires or circuit parts. For example, in a multi-functional small electrical appliance, use black heat shrink tubing to wrap the main power cord, and use other colors of heat shrink tubing to wrap the wires of different functional modules, which is convenient for subsequent repair and maintenance.
