Specific embodiment
Following embodiment only exists in illustrative purpose, limits the scope of the invention without being intended to.
Embodiment 1
As shown in Figs. 1-2, the upper end of a kind of energy-saving and environment-friendly automatically cleaning chimney, including chimney body 1, chimney body 1 is logical
Excessive root connecting rod 2 is fixedly connected with rain visor 3, and rain visor 3 can be used for preventing rainwater or other sundries from entering in chimney
Stainless steel material, the side wall of chimney body 1 are equipped with water storage cavity 4, and water storage cavity 4 is ring-type, and water storage cavity 4 passes through water inlet pipe 5 and row
Water pipe 6 is connected to outside, on the one hand water inlet pipe 5 and drainpipe 6 make in water storage cavity 4 for replacing to the water in water storage cavity 4
Water temperature be maintained within the scope of suitable temperature, improve chimney body 1 to the cooling effect of fat particles, on the other hand can will
Water in water storage cavity 4 takes out, and is used, reduces the waste of resource, the lower inside wall of chimney body 1 is embedded with annular collector
Slot 7, annular collector slot 7 can be realized by clamping structure common in the art and is detachably connected with chimney body 1, be convenient for
Annular collector slot 7 is cleared up, annular collector slot 7 is arranged in up-small and down-big funnel-form, utilizes 7 import of annular collector slot
Greatly, small feature is exported, the flowing velocity to oil smoke can be increased, the lower end of rain visor 3 is rotatably connected to rotation axis 8, rotation
It has been fixedly and coaxially connected runner 9 on axis 8, multiple diversion trenches 10 being obliquely installed have been offered on the side wall of runner 9, when diversion trench 10
When by wind blows, runner 9 can be made to rotate with 8 center of circle of rotation axis, filter plate 11 is fixedly connected in chimney body 1,
Filter plate 11 is similar with air filtering core construction in the prior art for the flue dust in oil smoke to be adsorbed and filtered, and does not do superfluous
It states, filter plate 11 is set in outside rotation axis 8, and the lower end of rotation axis 8 is fixedly connected with the scraping article 12 being arranged in the shape of a spiral, when runner 9
When rotation, it will drive scraping article 12 and from top to bottom the inner sidewall of chimney body 1 cleared up, scraping article 12 is interior with chimney body 1
Side wall abuts, and the lower end of scraping article 12 is arranged close to the upper end of annular collector slot 7.
In the present embodiment, when oil smoke is discharged along chimney body 1, the inside of fat particles and chimney body 1 in oil smoke
When wall contacts, condenses, be attached on the inner sidewall of chimney body 1 to the cold, it should be noted that can be by water storage cavity
4 carry out changing water, increase to avoid the constant temperature of chimney body 1, the condensation effect to grease are improved, at the same time, in oil smoke
