The specific embodiment

Embodiment 1: with reference to Fig. 1 and 2.A kind of warming stove, comprise housing 14, in housing 14, pass through baffle interval feed box 13 and heating chamber 4, hopper 13 is positioned at heating chamber 4 rear sides, heating 4 bottoms, chamber are provided with combustion chamber 10, between housing 14 interior hopper 13 bottoms and combustion chamber 10, be provided with pay-off, described pay-off comprises feeding motor 26, the passage 20 being communicated with combustion chamber 10, feeding spiro rod 11, described feeding spiro rod 11 is positioned at passage 20, the clutch end that feeding spiro rod 11 stretches out the outer one end of passage 20 and feeding motor 26 is in transmission connection, in described combustion chamber 10, be provided with electrically heated rod 3, its upper end is provided with slope shape guide plate 7, slope shape guide plate 7 is provided with some wind-guiding aperture 7a, the diameter of described wind-guiding aperture 7a is 2mm-8mm.10 belows, described combustion chamber are provided with remains of firebox 1, between membrane backside and hopper 13, be provided with smoke discharging pipe 24, smoke discharging pipe 24 ends are provided with smoke exhaust fan 25, passage 20 bottoms are provided with guide duct 23, and guide duct 23 one end are communicated with combustion chamber 10, and its other end is communicated with smoke discharging pipe 24, heating chamber 4 upper front end are provided with air outlet 5, hopper 13 and heating 4 belows, chamber are provided with air guide duct 21, and housing 14 is outer is provided with cooling fan 19, and the air outlet of cooling fan 19 is communicated with air guide duct 21.Heating chamber 4 front ends are provided with fire door 2, and remains of firebox 1 front end is provided with ashes door 1a.Heating 4 tops, chamber are provided with the feeding chamber 6 being communicated with hopper 13, are provided with feed box 62 in feeding chamber 6.

Body of heater demarcation strip 8 and thermal insulation board 9 that described dividing plate is arranged by gap form, and described smoke discharging pipe 24 is arranged between body of heater demarcation strip 8 and thermal insulation board 9.

Hopper 13 bottom pay-off one sides are provided with blanking pendulous device, blanking pendulous device comprises stroke-limit plate 18, the driving cam 25 being connected with feeding motor 26 output shaft ends, the slide cover 12 that is arranged at hopper 13 discharging openings, gyroaxis 17, plate 15, plate 15 upper ends are connected with slide cover 12 ends, its lower end is radially connected with gyroaxis 17, gyroaxis 17 stretches out the outer one end of housing 14 and is connected with stroke-limit plate 18, and stroke-limit plate 18 radially slides and is connected with driving cam 25.

Feeding motor 26 drives feeding spiro rod 11 that fuel is progressively pushed to the interior burning in

combustion chamber

10,26 rotations of feeding motor drive driving cam 25 to rotate simultaneously simultaneously, by driving cam 25, drive stroke-limit plate 18, and then drive plate 15 to act on slide cover 12 by gyroaxis, making slide cover 12 1 open one closes, and the time of closing of opening is controlled between 30 seconds to 90 seconds, namely hopper and pay-off play heat insulation effect by slide cover 12 is isolated, have also just played fireproof effect.Fuel is opened one by one of slide cover 12 and is closed and fall into pay-off and be pushed to combustion chamber 10 by the helical blade of feeding spiro rod 11, and the fuel previously having burnt burning is slowly complete, and along arc slope shape guide plate 7, squeezed into 10 tops, combustion chamber by fuel below, and ash after final burning is fallen in remains of firebox 1.Like this when lighting a fire use each time, as long as have fuel in hopper, feeding motor 26 driving fuel are squeezed away the residue of combustion residue last time in combustion chamber 10, just can continue to use, the time of saving each labor cleaning, and totally pollution-free, and clearance time once must be cleared up once by original every use, generally be no more than 36 hours the longest service time at every turn, change into as long as grey box residue is cleared up less than not needing; During the most important, when needing only fuel size suitably, just can push to the interior burning in combustion chamber 10 by pay-off, domestic current rural area is very many but second-rate, and during burning, the particle after machining such as the stalk of easy coking, kaoliang stalk can be used.Because slide cover 12 areas are larger, the coal cinder of suitable size and coal dust just can burn, and have increased fuel type simultaneously.

It is to be understood that: although the present embodiment has been done more detailed explanation to the utility model; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation, all fall in protection domain of the present utility model.
