Description

Micro-type alternating/direct current dual-purpose blower for honeycomb briquette stove

The utility model is interchange, the DC dual-purpose micro-blower that is used for honeycomb briquette stove.

The honeycomb briquette stove (kitchen range) of upward general family of society use at present all is to utilize natural convection air combustion-supporting in combustion process.The shortcoming of this kind mode: the one, firepower comes slowly and can not regulate, and particularly firepower is very weak during blow-on or after changing coal, and it is consuming time many to heat up water, do meal; The 2nd, there is a large amount of harmful gases to produce.At above-mentioned disadvantage, the someone has designed the blower of similar blower, and this burning device that helps is placed outside the fire door, and the wind supply quantity in the time of can increasing the honeycomb briquet burning saves time." the miniature combustion-supporting machine of honeycomb briquet " with Ac is used as power, power is 15W that east, Fujian Electrical Appliance Industry Company produces just belongs to this device.This kind power of fan is too big, has only the two-stage speed governing, admittedly be not suitable for home-use.In addition, also have dryelement cell of a kind of employing to be used as power, make the blower of casing, movement with plastics, though this blower power is moderate owing to can only use dryelement cell to make the energy, can not speed governing, unmatched fan housing again, applicability is relatively poor, and safety inadequately in use, and the cinder that particularly inside and outside plastic components is easily fallen burns out.Therefore, use is subjected to certain limitation, is difficult to promote.

The purpose of this utility model is to propose meter and a kind ofly not only can have utilized DC electrical source, but also can utilize ac power supply to be used as power, simple in structure, easy to use, reliable, and the miniature cartridge type blower fan that can carry out stepless speed regulation, to be used for family's wind nest coal stove, reach and save time, improve firepower, the purposes such as generation of harmful gas when reducing blow-on and changing coal.

Solution of the present utility model is to utilize the iron sheet tube of band certain taper to make casing, be loaded in the same pipe as movement with micromachine (can adopt the children toys motor) and as the dryelement cell of DC electrical source, and being fixed in the axial location of casing by locating piece, the fan page or leaf is loaded on the motor shaft; Ac is then imported by special-purpose jack after rectification; Arrangements for speed regulation then adopt the potentiometer shunt resistor to constitute, and reach the purpose that changes its rotating speed by electric current and the voltage of adjusting the input micro motor.This blower fan can directly insert fire door and use, and falls in the casing in order to prevent the cinder after foreign matter or the burning, all loads onto shielding can at the casing two ends to prevent to burn out blower fan.

The utility model is simple in structure, uses reliable.Owing to adopt stepless speed regulation, therefore in use convenient especially, not only firepower comes soon but also easy to control, power saving.From the blow-on door or add new coal and see flame to full hole, need 17 minutes without this blower fan, adopt this blower fan only to need 9～10 minutes; Boiled 5Kg water in combustion process does not use blower fan to need 20 minutes, uses blower fan then only to need 13 minutes, can shorten the time about 35%, and must go on the firepower when needing big fire, gets under the firepower when needing little fire.With a family of five is example, makes meal at every turn and generally can shorten about half an hour time under square one, also can reduce harmful gas pollution simultaneously.

Embodiment

To use diameter is that the honeycomb briquette stove of φ 120mm is an example, and when the fire door diameter was φ 60mm, casing 2 top diameters were φ 58mm, and diameter at butt end is φ 70mm, longly is 125mm, is that the thick galvanized sheet iron of 0.5mm rolls, is welded with material; Before fan housing 1 be zinc-plated silk screen, back cover 9 is made for the thick iron sheet of 0.3mm; Connecting sleeve 3 between fan page or leaf 13 and the micromachine 4 adopts the processing of H62 brass bar, and its external diameter is φ 10mm, and is long for 5mm, adopts stationary fit between connecting sleeve and the machine shaft.Micromachine 4 adopts WZY-151-1 type shaver motor (batch process can adopt inexpensive children toys motor to get final product); In pipe 5 be φ 32mm for polyethylene pipe, external diameter, internal diameter is φ 25mm, longly is 83mm, movement fixed block 6 adopts the galvanized sheet iron with the casing same specification; It is the silicon bronze sheet making of 0.5mm that the negative spring sheet 8 of battery 7 adopts thick, and speed governing knob 10 diameters are φ 10mm, and potentiometer 11 is the potentiometer with switch of 4.7K, and battery positive terminal 12 is selected the straight pin of φ 3 * 35 for use.Fan page or leaf 13 external diameters are φ 50mm, and material is the thick aluminium flake of 0.5mm.14 is that 15 is the fixed plate of potentiometer 11 through the Ac jack after the rectification (also rectifier can be loaded on the blower fan).

Rectifier adopts the wide L of tongue ₀=8mm, window width L ₁The E8 iron core of=9mm, the high H=16mm of window, primary turns are 4715 circles, line footpath φ 0.07mm, number of secondary turns is 135 circles, and line directly is the transformer of φ 0.4mm, and output voltage is that 6V(exchanges), electric current is 300mA, and the load voltage after rectification is 2V, and electric current is 150mA; Commutation diode is selected IN4004(electric current 1A, withstand voltage 400V for use), filter capacitor is 470uf, (can adopt commercially available same specification rectifier when producing in batches).

Speed regulator is that one 10 Ω, 1/2W metal film resister in parallel form on 4.7K potentiometer with switch 11.Speed adjustable range: when using dryelement cell is 0～250 rev/min, when using ac power supply is: 150～300 rev/mins.
