Abstract
The utility model provides an electric cooling and heating fan, which comprises a fan head, a front net, a big blade and a rear net, wherein the big blade is installed at the front end of the main shaft of the fan head, the front and the rear nets are fixed at the front end of the shell of the fan head through net hoops, and a small blade is installed on main shaft of the fan head at the rear side of the big blade; a heating tube protective net, a heating tube and a reflection shell are fixed in the inner cavity of the rear net; the heating tube is positioned between the heating tube protective net and the reflection shell; and the heating tube is electrically connected with the fan head. The utility model has simple structure and is easy to manufacture. When the fan is used in summer, the big blade guides wind, when the fan is used in winter, the small blade conducts heat, so the utility model has high thermal efficiency and reduces the heat loss. A carbon fiber tube or halogen fiber tube is adopted, so the utility model is durable and can be firmly positioned.
Description
Technical field
The utility model relates to tame electro-technical field, more particularly relates to the technological improvement of electric fan.
Background technique
At present, being seen electric fan on the market, major part is that summer is cool used, all is warm-air drier or warming furnace and warm oneself used winter, fan is used rare as warming oneself winter.Chinese patent " a kind of cold-warm fan ", the patent No.: 200520012898.0, a kind of cold-warm fan is disclosed, comprise equipped mutually body, electric machine assembly and front mesh enclosure assembly, body has front panel, indent circle and rear net cover, wherein, body indent circle circle mouth is fitted with heater, this heater leads to lead, and this lead is electrically connected the control switch that is positioned at the body front panel, realizes that by heating function after conductive rubber or conductive plastic or ceramet self energising system is warm; This heater has the heating inner ring, along outward extending at least three the heating supporting frames of the heating equal radian of inner ring periphery, and the heating outer ring of the supporting frame support of should generating heat; Heating outer ring periphery is shaped on circle along the circle mouth of portion in order to cooperation body indent circle; Heating inner ring suit electric machine assembly; There is one to be shaped on hollow cavity in the heating supporting frame, in order to run through the circuit that is electrically connected electric machine assembly.The cold-warm fan that it is simple in structure, cost is low, utilization efficiency is high, it has the structure of Hot-air fan and air-cooling fan concurrently; Can satisfy numerous consumer groups' demand.Chinese patent " exchange type cold-warm fan ", the patent No.: 200720110141.4, this patent provides a kind of exchange type cold-warm fan, comprise fuselage, blower fan, described blower fan is installed in the fuselage, on described fuselage, be provided with exhaust outlet, intake grill, described cold-warm fan also comprises having heat radiation/vaporizer of cold scattering effect, conducting tube, water pump and the seal case that is used to place low-temperature receiver or thermal source, described vaporizer is installed in order on the sealing plate of isolating the upper and lower air, described sealing plate is tightly connected with waist, described blower fan is installed in the top of vaporizer, and described exhaust outlet is located at back, and described import wind is located at underbelly; Described seal case is positioned at fuselage bottom, and described conducting tube is placed in the seal case, and the two ends of described conducting tube connect the import and export of the cold and hot conduit of vaporizer respectively by water pipe, on described water pipe water pump is installed.The utility model provides a kind of exchange type cold-warm fan that improves sanitary condition, strengthens cooling effect.But this class fan because air quantity is excessive, causes heat loss excessive when warming oneself winter.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure overcoming the deficiencies in the prior art, and cost is low, provide that heat is big, parts are few and make and be easy to the changes in temperature electric fan.
The utility model can take following technical measures to solve:
A kind of changes in temperature electric fan, contain head, preceding net, big blade, back net, big blade is installed on the front end of head spindle, and the shell front end that net hoop is fixed on head is crossed by preceding net, back Netcom, and its structure outline is: on the head spindle of the back of big blade little fan blade is installed; In the inner chamber of back net, be fixed with heating tube catch net, heating tube and refecting cover; Heating tube is positioned at the centre of heating tube catch net and refecting cover; Heating tube is electrically connected with head.
Above-mentioned heating tube is carbon fiber pipe or halogen fibre pipe; Heating tube is one or more, takes serial or parallel connection to be electrically connected.
Above-mentioned heating tube is rounded, triangle, quadrilateral or parallel in any shape.
Temperature regulation switch also is installed on the shell of head, and temperature regulation switch is electrically connected with heating tube.The beneficial effects of the utility model are:
1, the utility model is simple in structure, making is easy.
2, the utility model adopts big blade, little fan blade, uses the big blade wind-guiding summer, uses little fan blade heat conduction winter, and thermal efficiency height reduces heat loss.
3, the utility model adopts carbon fiber pipe or halogen fibre pipe, and is durable in use, firm position.
