When the main water level meter 49 monitors that the height of the water in the water storage tank 10 reaches a minimum set threshold value, the signal is transmitted to the control panel 8, the control panel 8 controls the electric switch 48 to be turned on, external water enters the water storage tank 10 through the external water pipe faucet 47, when the main water level meter 49 monitors that the height of the water in the water storage tank 10 reaches a maximum set threshold value, the signal is transmitted to the control panel 8, the control panel 8 controls the electric switch 48 to be turned off, automatic water replenishing is achieved in the water storage tank 10, the water discharge pipe 50 on the water storage tank 10 is used for discharging excess water in the water storage tank 10 to the outer side of the fireplace, and therefore intelligent indoor humidification and automatic water replenishing are achieved while warm air is conveyed indoors.
As shown in fig. 4, the filter screen 40 can be bonded to the intrados of the filter screen in the process of filtering the dust in the flue gas and accumulate the dust, it is not convenient to clean, and the air current in the air duct 13 drives the impeller 28 to rotate in the upward conveying process, thereby making the impeller 28 drive the roller 26 to rotate through the first rotating shaft 27, and further making the roller 26 drive the second rotating shaft 45 to rotate through the first gear 30 and the second gear 44, the rotation of the second rotating shaft 45 synchronously drives the brush strip 46 to rotate, thereby making the brush strip 46 clean the intrados of the filter screen 40, thereby realizing the automatic cleaning of the filter screen 40, time and labor are saved, and the efficient filtering effect of the filter screen 40 is maintained.
The roller 26 drives the slide bar 31 to do linear reciprocating motion through the annular groove 29 in the rotating process, so that the slide bar 31 drives the piston plate 34 to do reciprocating linear motion in the cylinder barrel 33 through the pull rod 32, when the piston plate 34 compresses the left cavity of the piston plate, the guide direction of the one-way valve 35 corresponds to the guide direction of the cavity and the guide direction of the two-way valve 36 points to the shunt pipe 38, so that air in the cavity is conveyed to the shunt pipe 38 through the first air pipe 37, is shunted to each air nozzle 39 through the shunt pipe 38, and is blown to the outer arc surface of the filter screen 40 through the air nozzles 39, so that dust blocked in the mesh holes of the filter screen 40 is blown out from top to bottom, and the efficient and stable filtering efficiency of the filter screen 40 on the dust in the smoke is kept.
Piston plate 34 makes the right side cavity volume grow to the left side cavity compression simultaneously to produce suction, because the direction of switching on of check valve three 41 points to evaporation pond 12, the direction of switching on of check valve four 42 points to corresponding the cavity, thereby make the warm air in the wind channel 13 get into through trachea three 56 and check valve four 42 the cavity, when piston plate 34 compressed the right side cavity, make the warm air in the right side cavity get into the inside of evaporation pond 12 and heat the water liquid in the evaporation pond 12 through trachea two 43, thereby improve water liquid evaporation efficiency, and then improve the humidification effect, piston plate 34 makes the left side cavity volume grow to the right side cavity compression simultaneously, and produce suction, thereby inhale high temperature flue gas through check valve one 35, so that clean filter screen 40 in the next time, so the circulation is reciprocal, plays the effect of self-cleaning filter screen 40.
The foregoing shows and describes the general principles, principal features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
