The invention discloses a residual heat and waste heat utilization structure of a small solar warmer. A heat gathering groove (8) installed on the upper edge of a reflector can gather hot air which rises to the position of a hole (9). Then the hot air is drawn in by a fan (7) through a pipe (10) and is further heated through a metal honeycomb or radiating fins (5) after being delivered into a halogen tube hollow bracket (3) or an electric wire ceramic body (12). Finally, the hot air is blown towards a human body through an air delivery pipe (4) which extends out of the safety guard net (2) of a heat source and realizes double heating effects together with the infrared heat. According to the invention, the residual and waste heat of a conventional small solar warmer is utilized so as to realize double heating effects provided by infrared rays and hot air. The electricity consumption of a traditional product is reduced in multiples, while the warming is faster. The residual heat and waste heat utilization structure of a small solar warmer has the advantages of higher temperature, high efficiency, energy saving, great invention and commercial value and remarkable social benefits.
