As shown in Fig. 1 to Fig. 7, a kind of energy storage type chalkboard eraser with supercharger, base plate 11 outer wall at shell 1 is provided with the strip rub piece 12 of one or more, shell hollow, arranges multiple suction hole 13 communicated with shell endoporus round rub piece on base plate；It is provided with the powder drum 2 of cylindrical hollow in the enclosure, powder drum one end open down, shell short side plate down arranges the equipment opening 14 corresponding with the opening of powder drum, it is provided with demarcation strip 3 one piece parallel with base plate 11 along powder drum outer wall, make a part for powder drum between demarcation strip and base plate, edge along demarcation strip 3 is provided with the surrounding edge that base plate is prominent, and the surrounding edge of demarcation strip surrounding is pressed on the base plate of shell, makes the suction hole 13 on base plate be arranged in surrounding edge endoporus；Powder drum wall between demarcation strip and base plate arranges multiple suction powder hole, enables chalk dust to pass sequentially through suction hole, inhale powder hole entrance powder drum；Base plate outside the surrounding edge being positioned at demarcation strip arranges multiple venthole 15；Described the chalkboard eraser of automatic dust absorption can also include collection powder cabin 4, filter 5 and supercharger 6；The described collection powder cabin one end open other end is closed, and is provided with a bracer of the two or more symmetric arrays to inner process in collection powder cabin near the inwall of opening；Filter is the hollow cylindrical that one end open is closed in one end, and the opening of filter is tapered, and the external diameter of the vertex of a cone is identical with the internal diameter of powder drum, and both form tight fit, and the diameter of the hollow cylindrical part of filter is less than the diameter of bore of powder drum；Filter is inserted collection powder cabin from the opening of collection powder cabin, the blind end making filter is against on a bracer, being predominantly located in of filter collects outside powder cabin, the filter being nested together and collection powder cabin are inserted in powder drum from the equipment opening of powder drum, the vertex of a cone making filter port end compresses powder drum inwall, both form tight fit, make, in space between filter and powder drum, the suction powder hole, to flow to supercharger from its opening after making the air-flow of entrance powder drum have to pass through the filtration of filter 5。
Described supercharger 6 mainly includes clockwork spring dish 61, clockwork spring 62, drive 63, driven pulley the 64, first bevel gear the 65, second bevel gear 66, ratchet 67, controls bar 68, fixing seat 69 and fan blade；Clockwork spring dish is placed in powder drum outer wall by clockwork spring dish axle, and clockwork spring dish can rotate around clockwork spring dish axle under the effect of external force。
Being provided with, near the sidewall of blind end, the fixing seat 69 that the blind end protruding from powder drum extends to shell in powder drum, described fixing seat one end is provided with drive axis hole, and the other end is provided with driven pulley axis hole。Described power axle one end is placed in drive axis hole, the other end is provided with the counterbore that the instrument with upper law caved inward matches, driving wheel tube is on power axle, and position corresponding with power axle on shell is provided with through hole, makes the instrument of law be inserted into counterbore；Follower shaft is through fixing seat, and one end is connected with driven pulley, and the other end and the first bevel gear 65 connect；Second bevel gear and the engagement of the first bevel gear, the second shaft of bevel gear is connected with fan blade in the blind end entrance powder drum of powder drum；Ratchet is arranged on the pawl axis on fixing seat。
Clockwork spring is placed in clockwork spring dish round clockwork spring dish axle, and one end of clockwork spring is fixed on clockwork spring dish axle, and the other end is fixed on clockwork spring dish inwall；Drive is divided into two-stage, and the outer wall of one-level away from fixing seat engages with the outer wall of clockwork spring dish, and the one-level near fixing seat is provided with ratchet, and the ratchet being meshed with ratchet is connected with the button on shell by controlling bar；Push button, control bar and promote ratchet, the ratchet making ratchet be rotated away from drive along pawl axis, enable drive freely rotatable；Decontrol button, while button resets, pull ratchet to make, between two adjacent ratchets that ratchet snaps on drive, to make drive not rotate by controlling bar。
The instrument wound up is inserted the counterbore on power axle and rotates, at this moment, owing to not pushing button, ratchet is positioned between two adjacent ratchets, the instrument wound up drives drive clockwise, enabling drive to back down ratchet to rotate, drive drives clockwork spring disc spins, thus tightening clockwork spring, stop operating the instrument wound up, due to the monodirectional locking effect by ratchet, make drive will not produce because of the Reverse Power of clockwork spring dish to rotate, so that clockwork spring dish can not rotate；By clockwork spring by power-reserve in clockwork spring dish。
Clockwork spring dish pushes button after storing power, and button promotes ratchet by controlling bar, makes ratchet leave the ratchet on drive, and the clockwork spring storing power will drive clockwork spring disc spins until the depleted of energy that stores of clockwork spring；Clockwork spring disc spins drives the drive engaged to rotate, and drive drives the driven pulley engaged to rotate again, and driven pulley drives the first bevel gear being coaxial therewith to rotate, and drives the second bevel gear to rotate, thus driving fan blade to rotate。
The instrument wound up is generally a knob being located on shell, it is necessary to when winding up, it is only necessary to pinches knob with hands and rotates。Counterbore on power axle is generally in-line or cross or hexagon, and the instrument wound up mates with counterbore。
Arranging airflow hole on powder drum wall between fan blade and powder drum blind end, airflow hole is positioned at the outer casing space between the top board of the shell relative with base plate and demarcation strip, and the air-flow after fan blade supercharging enters outer casing space through airflow hole。
Before using, first pass through the instrument wound up to tighten clockwork spring and stored power, push button during blackboard wiping, the power stored just is obtained in that release, the dynamic drive of clockwork spring dribbling rotates, drive drives driven pulley to rotate, driven pulley drives the first bevel gear to rotate, first bevel gear drives the second bevel gear to rotate again, thus driving fan blade to rotate, fan blade rotates chalk dust inspiration powder drum together with air, after being filtered, chalk dust stays collection powder cabin, clean air enters filter endoporus and flows to fan blade, it is blown into outer casing space through airflow hole after pressurized, it is discharged to outside shell again through venthole。
The shirt rim 16 that edge along base plate arranges downwards and extends internally, the height of described shirt rim is lower than the height of rub piece。It is subject to the guide function of shirt rim from the air-flow of venthole discharge, around chalkboard eraser, forms one gas curtain, it is prevented that chalk dust flies upward。
Powder drum is positioned at the height height less than the surrounding edge of demarcation strip of demarcation strip section below。
Filter adopts filter paper or filter cotton to make。
The roof of shell arranges arrow mark upwards。Making supercharger be positioned at above arrow, collection powder cabin is positioned at below arrow。The diapire of shell arranges Magnet, blackboard arranges iron plate, enable chalkboard eraser by magnet adsorption on blackboard。When placing chalkboard eraser, placing by arrow mark instruction, make arrow upward, the chalk dust outside filter will drop in collection powder cabin under gravity automatically。
Above-described embodiment is intended merely to the purposes of the interpretation present invention, and is not limitation of the present invention, and those skilled in the art in the essential scope of the present invention, make a variety of changes or substitute, also should belong to the protection category of the present invention。
