Fig. 2 is the Section A-A structural representation of Fig. 1.
Fig. 3 is the utility model electrical schematic diagram.
Specific embodiment
As shown in Figure 1, 2, 3, the utility model includes blower fan 1, reducing connecting tube 2 and electric heater unit, and described reducing is even
The miner diameter end of adapter 2 is communicated with the air outlet of blower fan 1, and described electric heater unit includes adapter sleeve 3,4, three heating of wind heating tube
Rod 5 and electric heating control module, described adapter sleeve 3 is provided with three electrically heated rod installing holes, and described adapter sleeve 3 is enclosed within reducing even
The bigger diameter end of adapter 2, one end of described wind heating tube 4 is connected on adapter sleeve 3, and described three heating rods 5 are respectively L font,
One end of three heating rods 5 is respectively and fixedly installed at three electrically heated rod installing holes on adapter sleeve 3, and the other end is located at respectively
In wind heating tube 4, described three heating rods 5 be in equilateral triangle arrange, described electric heater unit include heat stick controller 6,
Temperature sensor 7, Analog input mModule 8 and microchip 9, the two ends of described three heating rods 5 enter electric terminal respectively with
The current output terminal electrical connection of heating stick controller 6, the temperature value in foodstuff drying device monitored by described temperature sensor 7, and temperature passes
Sensor 7 passes through the communication of Analog input mModule 8 and microchip 9 and is connected, the control signal output end of described microchip 9 with add
