Foot warmer

The present invention relates to a warming device, and more particularly to a remotely controlled foot warming device.

In general, the elderly or people with poor peripheral blood circulation tend to have cold feet in the winter, and the temperature drop will make the blood flow slow, which will increase the poor circulation. Therefore, some people use hot water soaking feet, but the foot bath barrel filled with water is not easy to move, and the water temperature is cold, and it is easy to wet the home environment, causing many inconveniences.

Some manufacturers have developed electric heating devices, such as blade-type electric heaters. However, such electric heating devices tend to make the indoors too dry and cause skin problems for users or family members in the same room under long-term use. In addition, if it is too close to the electric heater, it may cause burns or burns on the skin. Therefore, the manufacturer develops the foot heating plate to allow the user's foot to contact the heating plate to increase the temperature of the foot and produce a warming effect.

However, the conventional foot heating plate is used to set the switch on the outer casing, and the user needs to bend over to operate the switch when the foot is heated. However, bending is a difficult operation for the elderly or the waist injured person, and thus There are still some inconveniences in use.
