A third flat plate 27 is rotatably arranged below the first flat plate 21, a plurality of first balls 28 are arranged between the first flat plate 21 and the third flat plate 27, so that the third flat plate 27 can freely rotate relative to the first flat plate 21, the sponge block 23 is clamped between the third flat plate 27 and the second flat plate 22, and a plurality of vertical liquid passing holes 29 are arranged on the third flat plate 27 for wiping oil.
A plurality of second balls 30 are mounted on the upper surface of the annular baffle 26, so that the second plate 22 can rotate freely relative to the annular baffle 26.
A third pressure spring 31 is connected between the third flat plate 27 and the second flat plate 22, and the third pressure spring 31 can enable the sponge block 23 to be quickly reset after being extruded.
The liquid outlet pipe 24 is provided with a liquid outlet one-way valve 32, so that the cleaning liquid in the sponge block 23 is prevented from flowing back when the sponge block 23 is extruded.
The lower end of the round pipe 8 is provided with a detachable end cover 33, and oil stains in the round pipe 8 can be cleaned by detaching the end cover 33.
When the portable oil box is used, firstly edible oil to be detected is filled in the oil box 4, the oil box 4 is placed on the base 1, the temperature sensor 5 extends into the oil box 4, the cover body 3 covers the base 1, the electric heating pipe 2 is connected, then the light source 11 is lightened, and the portable oil box can be plugged with commercial power and can also be powered by a portable power source.
The electric heating pipe 2 heats the edible oil in the oil box 4, the temperature sensor 5 measures the oil temperature and displays the oil temperature on the temperature display screen 6, and when the oil temperature is close to the theoretical smoke point of the edible oil, the electric heating pipe 2 is controlled to slow down the heating speed of the edible oil; when the edible oil is about to reach the cigarette point, if one strand or intermittent several strands of little cigarette has been produced, this little cigarette rises in the cover body 3 and gathers at cover body 3 top and discharge in 7 cigarette holes gradually, because communicating pipe 9 has certain interval and communicating pipe 9 slant arrangements down with cover body 3 top, and the flue gas rises, consequently a small amount of oil smoke gathering can't enter into pipe 8 through communicating pipe 9 at cover body 3 top, but discharges completely gradually through the cigarette hole 7 at cover body 3 top.
When the oil temperature reaches the smoke point and begins to produce continuous oil smoke, because smoke hole 7 discharges fume slowly, the oil smoke at the top of cover body 3 gathers more, wait when the oil smoke submerges the mouth of pipe of communicating pipe 9, the oil smoke can enter into pipe 8 from communicating pipe 9, and rise in pipe 8, the light that light source 11 sent makes photoelectric sensor 12 received light intensity weaken after the oil smoke scattering, photoelectric sensor 12 sends the signal and starts alarm device suggestion experimenter, record the temperature value that temperature display screen 6 shows this moment, be the edible oil smoke point who surveys promptly.
After the measurement is finished, the power supply is turned off, the cover body 3 is taken down, the pressing plate 19 is pressed downwards, the pressing plate 19 overcomes the second compression spring 20 to push the piston 17 to move downwards, the piston 17 extrudes the cleaning liquid in the liquid storage bottle 13 through the liquid outlet pipe 24, the cleaning liquid flows out of the liquid outlet pipe 24 and then flows into the sponge block 23 through the liquid hole 29, after the second compression spring 20 is pressed to the extreme position, the liquid storage bottle 13 is pushed to move downwards under the action of the first compression spring 14 by continuing to press, when the second plate 22 contacts the annular baffle 26, the outer side of the sponge block 23 is contacted with the inner ends of the two glass tubes 10, and the first plate 21 and the third plate 27 are enabled to compress the sponge block 23 by continuing to press the sponge block 23 to extrude the cleaning liquid in the sponge block 23 to be coated at the inner ends of the two glass tubes 10, meanwhile, the screw 25 moves downwards along with the first plate 21, and under the action of no self-locking thread, the second plate 22, the sponge block 23 and the third plate 27 rotate, so that the sponge block 23 wipes the inner ends of the glass tubes 10; after the pressing plate 19 is loosened, the piston 17 moves upwards under the action of the first pressure spring 14, outside air enters the liquid storage bottle 13 through the air inlet pipe 15 under the action of negative pressure in the bottle, meanwhile, the liquid storage bottle 13 moves upwards under the action of the second pressure spring 20, the first flat plate 21 and the third flat plate 27 move upwards relative to the second flat plate 22 under the action of the third pressure spring 31, and the second flat plate 22, the sponge block 23 and the third flat plate 27 rotate in the reverse direction under the action of the non-self-locking screw threads to wipe the inner end of the glass tube 10 again; after the two times of wiping, the oil stains at the inner end of the glass tube 10 are wiped clean, so that the oil stains are prevented from influencing the detection result of the smoke point.
When oil stains accumulated at the bottom of the circular tube 8 are more, the end cover 33 is detached to clean the end cover 33 and the circular tube 8; when the permeability of the inner end of the glass tube 10 is decreased, the glass tube 10 is replaced with a new one.
The invention filters discontinuous micro smoke which is easy to generate before a smoke point through the communicating pipe 9 which is arranged obliquely downwards, avoids the measured value of the smoke point from being lower, avoids the light source 11 and the photoelectric sensor 12 from being reduced by the smoke curing precision for a long time by isolating the light source 11 and the photoelectric sensor 12 from the smoke, can clean the inner end of the glass tube 10 in time by arranging the cleaning device, can keep the measuring precision for a long time, and simultaneously, the circular tube 8 is offset at the outer side of the oil box 4 and is not positioned right above the oil box 4, and can effectively avoid the influence of high temperature on the photoelectric sensor 12 during the measurement.
