Foot Warmer Structural Design

The main structure consists of a base plate and a ring-shaped cover. The base plate features a wave-shaped raised design to increase the heat dissipation area, evenly distributing heat while providing a foot massage function. The detachable expansion cover supports 56° opening and adjustment, creating a semi-enclosed space to improve the efficiency of warm air concentration. The bottom anti-slip foot pads are made of TPE silicone material with a friction coefficient of over 0.8, ensuring a displacement distance of less than 2cm when placed on wooden floors.
