Description

Micro-combustion heat is precious

Technical field

The utility model relates to the heating field, and particularly a kind of micro-combustion heat of micro-combustion heat supply of utilizing is precious.

Background technology

Gong Ying portable warmer mostly is rechargeable greatly and the chemical mediator warmer in the market.Rechargeable warmer generally be adopt that heat pipe, resistance wire, Electric radiant Heating Film etc. heat up, heat accumulation, outage insulation heating, as patent CN93219451.6 " Electric radiant Heating Film heat is precious ", this heat is precious owing to heat pipe, resistance wire, Electric radiant Heating Film poor corrosion resistance, so influence hot precious service life; The chemical mediator warmer, utilize chemical heat release to warm oneself, as patent CN200310113414.7 " Nano heat accumlator " and this hot treasured is some chemical substances of dress in the polybag of a sealing, sealing bag breaks easily, cause danger, and, also pollute the environment when sealing bag breaks or heat is precious eliminates when being thrown away; Also have other some heat precious, as patent CN03212342.6 " the convenient portable warmer of superconduction ", utilization be that the principle that the material phase-state change is emitted latent heat is warmed oneself.More than these heat is precious all can't use under the situation of non-transformer or thermal source, and can only use several hrs after heating or the charging at every turn, just need makeup energy once more, therefore very inconvenience need to improve.

Summary of the invention

For fear of with overcome above-mentioned deficiency, it is precious that the purpose of this utility model provides a kind of micro-combustion heat of utilizing the micro-combustion heat supply.

The realization the technical solution of the utility model is:

The hot treasured of micro-combustion mainly comprises: heat-storing material, the combustion chamber, the Wen Tuoli micro-mixer, fuel cylinder, electronic striking and steam supply valve isochronous controller, ignition, air supply pipe, it is characterized in that fuel in the fuel cylinder is transported to the combustion chamber by air supply pipe and burns, air hose is connected in the air supply pipe by the Wen Tuoli micro-mixer, the switch of steam supply valve and the igniting of fuel are controlled by steam supply valve control line and ignition control line respectively by electronic striking and steam supply valve isochronous controller, ignition is fixed in the combustion chamber, the combustion chamber of known " Switzerland's roll " formula is adopted in the combustion chamber, the combustion chamber places the precious centre of heat, from the combustion chamber outwards is refractory layer successively, heat-accumulating area, shell, with heat-barrier material fuel cylinder and heat-accumulating area are separated, electronic striking and steam supply valve isochronous controller and charge valve are fixed on the fuel cylinder, and can cover with buckle closure.Wherein the size of air supply pipe is equal to or less than the fuel quenching distance.

The utility model has the advantages that: make simply, cost is low, and control is convenient, need not other additional power source and thermal source, and service time is long, even can uninterrupted heat supply in continuous several days.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model structural representation,

Fig. 2 is the utility model profile.

As shown in the figure, number in the figure is represented respectively: 1. shell 2. heat-accumulating areas, 3. blast pipe 4. air hoses, 5. steam supply valve 6. fuel, 7. fuel cylinder 8. charge valves, 9. electronic strikings and steam supply valve isochronous controller 10. buckle closures 11. steam supply valve control lines 12. ignition control lines 13. Wen Tuoli micro-mixers 14. air supply pipes 15. ignitions 16. combustion chambers 17. refractory layers.

The specific embodiment

As shown in the figure, air hose (4) is connected in the air supply pipe (14) by Wen Tuoli micro-mixer (13), Wen Tuoli micro-mixer (13) can design according to hydromechanical Bernoulli equation and combustion chemistry balance, the size of air supply pipe (14) is equal to or less than the fuel quenching distance, in case the generation of non-return fire phenomenon, fuel (6) in fuel cylinder (7) is from air supply pipe (14) when flowing through, will be sucked into come and fuel (6) mixing after be transported to together in the combustion chamber (16) and burn, the igniting of the switch of steam supply valve (5) and fuel (6) is controlled by steam supply valve control line (11) and ignition control line (12) respectively by electronic striking and steam supply valve isochronous controller (9), ignition (15) is fixed in the combustion chamber (16), the combustion chamber of known " Switzerland's roll " formula is adopted in combustion chamber (16), combustion chamber (16) places the precious centre of heat, (16) outwards are refractory layer (17) successively from the combustion chamber, heat-accumulating area (2), shell (1), with heat-barrier material fuel cylinder (7) and heat-accumulating area (2) are separated, the settings of electronic striking and steam supply valve isochronous controller (9) and charge valve (8) fix on the fuel cylinder (7), and can cover with buckle closure (10).

During use, unlocking electronic sparking and steam supply valve isochronous controller (9), steam supply valve (5) is opened, fuel (6) flows in the air supply pipe (14), the Wen Tuoli micro-mixer (13) that is installed in simultaneously in the air supply pipe (14) also can suck air in the air supply pipe (14), and fuel and Air mixing gas just are transported to burning in the combustion chamber (16) by air supply pipe (14).The heat that burning discharges is transported to heat-accumulating area (2) through refractory layer and stores, and discharges slowly then, when not needing to warm oneself, closes electronic striking and steam supply valve isochronous controller (9) gets final product.When needs, can pass through charge valve (8) postcombustion (6).
