Abstract
The utility model discloses an active charging dust-cleaning blackboard eraser which comprises a machine body, an eraser head, a blower and a power supply, wherein the blower is installed on the machine body. The eraser head is arranged nearby the air inlet position of the blower, and a drive motor of the blower is connected with the power supply. The utility model is characterized in that a fan in the blower is a centrifugal fan, and an air outlet of the blower is sheathed with a dust collecting bag made of filter materials. The utility model has the advantages of ideal dust removing effect, simple and perfect structure and economical cost. After the utility model is popularized, the utility model thoroughly solves the problem of dust pollution in a classroom and avoids chalk dust damaging the physical and mental health of teachers and students.
Description
The utility model relates to a kind of device that erases the board, especially a kind of blackboard eraser with dust removing effects.
Blackboard is the conventional teaching apparatus of still continuing to use so far.Though with chalk on blackboard, write teaching tool have eye-catching, easily change, the outstanding advantage of economic dispatch, for a long time, the dust pollution during blackboard wiping is but troubling numerous teachers and students always.Dust pollution question when for this reason, many people once thought hard solving the blackboard wiping.Known to the tool applicant, the someone works out the blackboard eraser that utilizes the electrostatic precipitation principle and utilize the blower fan ventilation and dust removal at present, the former structure complexity, and cost is higher, and volume is big; The latter adopts aerofoil fan, and blast is low, and dust removing effects is poor, and the structure imperfection, therefore there is no popularization so far.
Main purpose of the present utility model is: at the above-mentioned existing deficiency that the dedusting function blackboard eraser exists that has, propose a kind of perfect, good dedusting effect rational in infrastructure and the economical and practical clean dirt blackboard eraser of active charging.
In order to achieve the above object, the clean dirt blackboard eraser of active charging of the present utility model comprises body, wipes head, blower fan, power supply, and described blower fan is installed on the body, installs near its air inlet place and wipes head, and the drive motors of blower fan connects power supply.Its improvements are that the fan in the described blower fan is a centrifugal fan, the dust bag that the air outlet socket is made by filtering material.
Behind the electrical power, centrifugal blower work, wiping the stronger negative pressure of head place generation, wipe blackboard wiping as using this moment, the chalk dust of kicking up will be under the effect of this negative pressure inspiration body rapidly, discharge from the air outlet of blower fan, under the filtration of dust bag, clean air is discharged from, and chalk dust then is trapped within the bag.Behind the full dust of dust bag collection, can change cleaning easily.Because centrifugal blower has stronger blast and air quantity, so the utility model dust removing effects ideal, and simple in structure perfect, cost economy after the popularization, with the dust pollution that thoroughly solves in the classroom, avoids chalk dust to the able-bodied harm of teachers and students.
Below by embodiment the utility model is further described in detail.
Fig. 1 is the front view of an embodiment of the utility model.
Fig. 2 is the vertical view (removing upper cover part) of Fig. 1.
Blower fan in the clean dirt blackboard eraser of active charging illustrated in figures 1 and 2 is made of motor 7, centrifugal fan 8 and spiral case 1, this blower fan is installed on the body 4, the rechargeable battery of its drive motors 7 tippings in battery case 11, the air inlet place of this blower fan is equipped with through the horn mouth of body 1 expansion and wipes 6, the dust bag (not shown) that air outlet is made by filtering material by dust mouth 9 sockets of elbow shape.Convenient for socket, be shaped on retraction slot near the termination of dust mouth 9.Body is provided with slide rail 13, and dust storehouse lid 10 is inserted on the body 4 by slide rail 13.In addition, 5 among the figure is supports, the 12nd, and the switch knob.
When pinning switch knob 12, motor 7 energisings, the centrifugal blower rotation, can suck this moment with wiping near 6 dust, is discharged in the dust bag by dust mouth 9 and collects.After dust bag is filled, take out down dust storehouse lid 10, just can change dust bag easily, continue to use.The clean dirt blackboard eraser of the active charging of present embodiment has compact conformation, in light weight, good dedusting effect, price economy, advantage such as easy to use.
