Abstract
The utility model is a combined type direct current fan, comprising a socket provided with a battery box in the inner side and arranged with a switch and a combined frame fixedly connected with the socket. The combined frame is provided with a plurality of fixed fan mechanisms composed of a motor, blades and a blade cover. A plurality of conducting wires connecting the motor are connected in parallel, and then are connected in series with a battery unit in the battery box. The combined type direct current fan can form relatively large power to satisfy the requirement of heat radiation and cooling, and can replace the function of the alternating current fan in the powering off and no power region. The combined type direct current fan is suitable for using in the field because of the moving at will, solving the problem of heat radiation and cooling of the field staff in hot summer, and improving the working condition of the field staff.
Description
Technical field
The utility model relates to a kind of DC fan.
Background technique
As the electric fan of heat radiation cooling, what sell in the market all is to exchange blade-rotating electric fan, its kind and in many styles, and power is bigger, uses but be only limited to the occasion that civil power is arranged, and leaves ac power supply and just can't use.Vehicle with DC electrical source can be used DC fan, but power is too little, and use occasion is restricted, as runs into power failure or field work, ac fan just can not be used, and this emergency condition happens occasionally, especially in summer of arid, power tense often has a power failure, and makes troubles for people's life.Therefore, the DC fan that provides a kind of power to be convenient to move at any time again greatly is people's a eager desire." DC fan " of the Chinese patent patent No. 97215060.9, by housing, flabellum, ball bearing, the stator combination that is provided with circuit board forms, it is to order about flabellum by stator generation magnetic field effect to rotatablely move after switching on, this electric current fan be unable to do without DC electrical source, using scope also is confined to have in the vehicle of DC electrical source, still can't solve the heat radiation cooling difficult problem under no city electricity condition.
Summary of the invention
Technical problem to be solved in the utility model all provides a kind of in the defective that overcomes prior art and can arbitrarily move, and need not the combined DC fan of ac power supply, is having a power failure or is not having under the electric emergency condition or heat radiation cooling problem during field work to solve.
Embodiment of the present utility model is:
A kind of combined DC fan, it comprises the base that is provided with switch, base is provided with the fan of being made up of motor, fan blade, blade cover, it is characterized in that described base is provided with and its fixing assembling frame, and the motor of a plurality of fans is connected in the assembling frame; Described base has the battery case that dryelement cell is installed; The battery pack that connects the multiple conducting wires of motor and connect in back and the battery case is in series.
Described a plurality of fan is 2-12.
Described battery pack is composed in series by No. 1 battery of 8-12 joint.
Described switch comprises time switch and speed control switch.
Described a plurality of fan is circumference assembled arrangement or rectangular assembled arrangement or square assembled arrangement or trapezoidal assembled arrangement or pentagon assembled arrangement or Hexagon combination arrangement.
The utility model is power supply with the dryelement cell, and a plurality of fan arrangement are become combined type, has overcome the little defective of power, can solve the heat radiation cooling problem of power failure and areas without electricity, because the non-transformer line links to each other, can arbitrarily move, and is more suitable in the field work demand.
Description of drawings
Fig. 1 is the utility model embodiment 1 arranging structure schematic representation;
Fig. 2 is the utility model embodiment 2 arranging structure schematic representation.
Embodiment
By above-mentioned accompanying drawing embodiment the utility model is elaborated again.
Shown in Fig. 1-2, the combined DC fan has the base 5 of battery case by plastic production in comprising, switch is located on the base, is made up of interchangeable time switch 4 in position and speed control switch 6.The fan of being made up of motor 3, fan blade 2, fan housing (not showing in the circle) is installed in the assembling frame 1 of the one that links to each other with base, energy-saving electric machine by combination fan and assembling frame are connected and form energy-saving combined type big fan, the arrangement style of fan is multiple, as Fig. 1 embodiment 1 scheme is the rectangular assembled arrangement, fan is 6, Fig. 2 embodiment 2 schemes are the circumference assembled arrangement, and fan is 7.
Be composed in series battery pack by No. 1 battery of 8-12 joint in base 5 battery cases, each fan electromotor 3 is connected on the battery pack positive and negative end after drawing lead and connecing together, the experiment proved that above-mentioned battery pack was enough used 4-5 hour, the battery of changing also can be done the torch illumination and utilize.
