Description

Technical field:

[0001] The invention relates to an electric heating rocking chair, belonging to small household electrical appliances. Background technology:

[0002] In winter, most rooms need heating, but there are many buildings, especially in the south and most of the rural houses in the country, which do not have central heating. Some of them have insufficient central heating or the indoor temperature is not enough before and after the beginning and end of the central heating season. Especially some elderly people have some diseases in their waist, back, legs, etc., and they feel more uncomfortable when the indoor temperature is low. Most of the elderly like to lie on recliners to rest, and rocking chairs are very popular among the elderly. If the elderly can still receive heat while lying on the rocking chair, their waist, back, legs and even the whole body will be warm and comfortable in winter. In other words, the rocking chair can be heated to become a thermal therapy chair. This chair should also heat up quickly, be safe and reliable, and have adjustable temperature. There is no such product on the market at present, and people are in urgent need of good products that can solve these problems. Summary of the invention:

[0003] The "electric rocking chair" we developed solves the problem that there is no such product on the market.

[0004] This kind of electric rocking chair uses steel tubular materials as the chair reclining frame, armrests, and rocking base frame of the electric rocking chair. A chair reclining board and leg rest board made of aluminum-magnesium alloy are installed on the chair reclining frame. The chair reclining board and leg rest board have heating elements and aluminum-magnesium alloy panels, which can heat the whole body. There is also a leather headrest for the head. The rocking base frame can make the chair rock. The electric heating part of the chair controls the surface temperature through a two-speed switch, and there is a power cord socket to connect the external power supply. There is a foot pedal at the front for easy placement of the feet, and there is a rocking base support frame underneath. The heating element is connected to a double over-temperature protector, which has good safety protection. The heating element also has double insulation protection of insulating sheet and outer protective film to ensure safety. The outer surface of the metal material of the electric rocking chair is sprayed.

[0005] When using it, you need to plug one end of the power cord into the chair and the other end into the indoor power socket. You can manually adjust the temperature in two settings.

[0006] The main body of the chair of the present invention is made of aluminum-magnesium alloy material. The aluminum-magnesium alloy material has a fast heat transfer speed, which is 5 times that of iron. The heat dissipation method is mainly infrared radiation. There is no liquid such as oil and water inside. It can be used indoors. It has high strength and does not rust. The surface temperature is generally adjustable between 30°C and 50°C. It has a waterproof design and can still work normally even when sprayed with water.
