Description
Technical field
The utility model relates to the realia field
Background technology
At present, the pollution of dust remains one of injury of the vast worker of educational administration maximum.Though people have done more work and effort to the improvement of blackboard eraser with innovation, all do not obtain substantial progress, the product that is gone out still exists various defectives and drawback, does not therefore obtain the recognition and acceptance in market.
Summary of the invention
In order to overcome the drawback of existing product, stop the injury of those barbaric dust continuation to human body.The utility model provides a kind of dust-collecting type electric blackboard eraser, and it is good that it has pick-up performance, and wiped clean is easy to use, small and exquisite characteristics such as attractive in appearance.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model is wiped seat (hereinafter to be referred as wiping seat) by dust-collecting type electric blackboard eraser rub body (hereinafter to be referred as rub body) and dust-collecting type electric blackboard eraser and is formed.
The outward appearance of rub body is rectangular-shaped, and there are power supply indicator and power switch in its surface.TunePower has been installed in rub body, dust absorption fan, the dust suction fan blade, the dust-filtering net is wiped tube motor and lint and is wiped spare and accessory parts such as tube.When using, lip-deep power switch is opened.Wipe a tube motor and promptly start working, because the rotor of two wiping tube motors of installing side by side is fixedly mounted on the rub body, stator rotate, thereby is installed in lint that stator makes a circle outward and wipes tube and will carry out wiping to blackboard under the effect that stator rotates.The direction of rotation of two fine hair wiping tubes all is to rotate relatively from outside to inside, can produce one air-flow to the centre in blackboard wiping, and this strand air-flow also can be carried dust secretly and be discharged by the dust-filtering net under the guiding of two dust absorption fans this moment.For forming the dust around the rub body, the wind that prevents to discharge flies upward.Specially having designed one in the inside of rub body is the annular passage at center to wipe tube, so that allow air draft be inhaled into once more, forms circulating current.
The outward appearance of wiping seat also is a shape that is cuboid, and it is to be fixed on the wall or other object surfaces on the blackboard limit with other auxiliary material.Wipe a dust box and a cover power transformer unit have been installed in the seat.This cover power transformer unit adopts 220 volts of voltage inputs, and its output voltage is that dc low-voltage replenishes power supply for the TunePower in the rub body.At the upper surface of wiping seat one group of dust box push rod and one group of attaching plug are arranged.When just being shelved under the common no situation, wipes on the seat rub body.The dust chamber cap and the supply socket of its dust box push rod and attaching plug and rub body bottom match.At this moment, the lip-deep power supply indicator of rub body also can show the power transformer unit of wiping in the seat, the TunePower in the rub body is replenished power supply.The dust chamber cap of rub body bottom will be opened because of jack-up under the effect of dust box push rod simultaneously, and the dust in the dust room also can unload automatically and fall in the dust box at this moment.Under the wiping seat, a chamber door is arranged.When the dust in the dust box is accumulated to certain amount, just can open chamber door.Dust in the dust box is disposed.
The beneficial effects of the utility model are: when when using the utility model blackboard wiping, two electronic wiping tubes in it not only can get the blackboard wiping very clean, and the dust that is produced when two dust absorption fans in it also can be with wiping simultaneously all sucks in the dust room in the rub body.

The specific embodiment
Shown in Figure 1 is the front view of the utility model (rub body), and power supply indicator (2) has been installed on the surface of its rub body frame (1), power switch (3), and battery case cover plate (4).
The utility model as shown in Figure 2 (rub body) E-E view.In rub body frame (1), probably can be divided into three structure sheafs.The A-A view that is Fig. 3 is first structure sheaf, in the rub body frame (1) of this aspect, one group of TunePower (5) has been installed, two dust absorption fans (6) have been installed on its position intermediate, while has also been installed a supply socket (11) on the position in the lower right corner of rub body frame (1), the various electric parts in its rub body frame (1) all are connected with electric wire respectively.The B-B view of Fig. 4 is second structure sheaf, both sides in the rub body frame (1) of this aspect, a dust-filtering net (8) has been installed respectively, on its position intermediate, there are two dust suction fan blades (7) to be installed on the axle of dust absorption fan (6), bottom at dust suction fan blade (7) is a dust room (12), a dust chamber cap (13) is arranged at the bottom of dust room (12), D-D view in conjunction with Fig. 6 can be seen, dust chamber cap (13) is installed on the interior little bar of rub body frame (1), and by spring (14) dust chamber cap (13) is remained under the normally closed state.The C-C view of Fig. 5 is the 3rd structure sheaf, in the rub body frame (1) of this aspect, installed two side by side and wiped tube motor (9), these two rotors of wiping tube motor (9) are installed in respectively on the rub body frame (1), and the periphery of its stator has been installed lint and wiped tube (10).
Fig. 7 is that the F of the utility model (rub body) is to view.Be the bottom view of rub body frame (1), a dust chamber cap (13) is arranged in the centre of this bottom surface, simultaneously the supply socket (11) in addition on this bottom surface.
Shown in Figure 8 is the front view of the utility model (wiping seat).A dust box and a cover power transformer unit have been installed in wiping base framework (17).Wipe the upper surface of base framework (17) at it, the vertical view of the utility model promptly shown in Figure 8 (wiping seat) as seen has one group of dust box push rod (15) and one group of attaching plug (16).
Operating process of the present utility model is as follows:
In use, the lip-deep power switch of rub body frame (1) (3) is opened.Wiping tube motor (9) promptly starts working, because the rotor of two wiping tube motors of installing side by side (9) is fixedly mounted on the rub body frame (1), stator rotates, thereby is installed in lint that stator makes a circle outward and wipes tube (10) and will carry out wiping to blackboard under the effect of stator rotation.The direction of rotation of two fine hair wiping tubes (8) all is to rotate relatively from outside to inside, in blackboard wiping, can produce one air-flow to the centre, this strand air-flow also can be carried dust secretly and be discharged by dust-filtering net (8) under the guiding of two dust suction fan blades (7) this moment.For forming the dust around the rub body, the wind that prevents to discharge flies upward.Specially having designed one in the inside of rub body is the annular passage at center to wipe tube, so that allow air draft be inhaled into once more, forms circulating current.
Wipe on the seat when rub body just is being shelved under the common no situation, its dust box push rod (15) and attaching plug (16) match with the dust chamber cap (13) and the supply socket (11) of rub body bottom.At this moment, the lip-deep power supply indicator of rub body frame (1) (2) also can show the power transformer unit of wiping in the base framework (17), the TunePower (5) in the rub body frame (1) is replenished power supply.The dust chamber cap (13) of rub body frame (1) bottom will be opened because of jack-up under the effect of dust box push rod (14) simultaneously, and the dust in dust room's this moment (12) also can unload automatically and fall in the dust box.Under the wiping seat, a chamber door is arranged.When the dust in the dust box is accumulated to certain amount, just can open chamber door.Dust in the dust box is disposed.
