Abstract

The utility model discloses a collector for eraser dust, which comprises a housing provided with an air inlet on one end and an air outlet on the other end, a collecting cavity connected with the air inlet, an air sucking device composed of a fan and a motor, a power supply for supplying an energy source to the motor, and a switch for controlling the on-off of the motor, wherein the air inlet forms a narrow-seam shape which is used for forming an airflow for blocking the leakage of eraser dust. The utility model has the advantages of portability, simple operation, guarantee of high-efficiency collection and leakage prevention to the eraser dust.

Description

Rubber bits cleaner

The utility model relates to the battery-operated vacuum cleaner of hand held that is used to collect the rubber bits.

Rubber can be wiped the vestige of pencil or ball pen, is office and of great use apparatus in study., rubber always stays the rubber bits after usefulness.For a long time, people rely on artificial blowing or manual removal rubber bits always.This common sweep-out method was both time-consuming, and efficient is low again, but also caused environmental pollution.Although rubber has been used for a long time, people also do not have a kind of device of the effective removing rubber bits that are improved.

United States Patent (USP) 5,084,937 and 5,105,497 disclose a kind of rubber bits cleaner and a kind of motor-driven eraser respectively.Can collect the rubber bits in order to reach when wiping rubber, these two kinds of devices have all used rubber support and air draught facility, and are provided with suction pipe, storage, baffle plate and inner suction pipe.During work, said apparatus utilizes the official post rubber bits of the air velocity in suction pipe and the inner suction pipe to be deposited in the storage.In order to prevent that rubber bits from leaking, need keep specific assurance during use, place and carry posture.

Along with improving constantly of people's standard of living, the problem of removing the rubber bits becomes more and more important.For this reason, it is a kind of not only easy to carry that the utility model is intended to provide, and rubber bits cleaner simple to operate, that removing is satisfactory for result.

In order to realize the foregoing invention intention, rubber bits cleaner of the present utility model comprises that an end has air intlet, the other end that the shell of air outlet slit is arranged, a collecting chamber that links to each other with air intlet, the getter device of forming by fan and motor, be used to provide the power supply of the motor energy, the switch that the control motor is opened or stopped, described air intlet has the narrow slit shape, can prevent that the rubber bits from leaking, be used for stopping that rubber bits and the filter that allows air pass through place between the described air import and export.

Rubber of the present utility model bits cleaner can the collection work place the rubber bits, easy to carry, simple to operate, its air intlet has the characteristics of shape of slit and has guaranteed efficient collection, and collecting chamber is closed to prevent that the rubber bits from leaking.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the front view of an embodiment of the utility model.

Fig. 2 is the vertical view of Fig. 1 embodiment.

Fig. 3 is the right view of Fig. 1 embodiment.

Fig. 1 has a rubber bits Integrated Chip chamber 4 to the housing 2 of rubber bits cleaner shown in Figure 3.One end in this Integrated Chip chamber connects an air intlet 3, and the other end connects air intake device.This air intake device is made up of fan 6, fan hub 8 and motor 7.Between air intlet 3 and air outlet slit 12, settle a filter 5.Motor 7 is driven by battery 9 or rechargeable battery, and is subjected to switch 10 controls.After covering movably top cover 11, constitute a complete vacuum systems.

In order to reach the main purpose of collecting the rubber bits, the utility model has adopted an air intake device, is provided with an Integrated Chip chamber 4.When fan 6 runnings, between air intlet 3 and air outlet slit 12, produce air-flow and in Integrated Chip chamber 4, produce vacuum.At this moment, the rubber bits are filtered device 5 then and block along with air-flow sucks from air intlet 3.Air by filter 5 then discharges from air outlet slit 12.

During use, the operator needs to grip slightly obliquely this rubber bits cleaner 1, or with itself and working face keeping parallelism, presses switch 10 simultaneously, air intlet 3 is contacted or near working face.Like this, the suction that produces of rubber bits cleaner just can be removed near the rubbers bits the air intlet 3.When this rubber bits cleaner of gripping is mobile on paper or on the desktop, just can clean bigger working face at an easy rate.Because this rubber bits cleaner volume is very little, therefore can grip operation with a hand easily.Compare with traditional blowing or with the method that hand is removed, obviously rubber bits cleaner is respond well, and has avoided pollution.

One big characteristics of present embodiment are the special air import designs of effectively removing the rubber bits.The cross section of the air intlet 3 of present embodiment is a shape of slit.Air intlet with shape of slit can provide the working width of a broad, and keeps high velocity air in the zone near working face.The rubber bits are biapiculate excellent type shape usually.The gap of slit can be approximately greater than ten times of rubber bits average diameter.The bottom of air intlet 3 has straight and sharp edges, so that can shovel the loose rubber bits that are bonded on the paper like a cork as scraper when needed.In addition, narrow air intlet has the function that prevents that the rubber bits from leaking.

It is adjustable air intlet designs that present embodiment also has characteristics, promptly is provided with handles 14 door 13 at air intlet 3 places.When promoting handle 14 forward, the door 13 of air intlet 3 can Close All.Such design has further prevented leakage, so be well suited for being carried in student's the school bag.

In addition, in order to reach the purpose of this utility model, air cleaner 5 places between the import and export.After opening top cover 11, being collected in the Integrated Chip chamber 4 rubber bits can outwell.Air cleaner 5 also can be replaced with disposable filter.

Need to prove that at last the shell of the utility model rubber bits cleaner can be different shape, comprising anteater or other animal, or car etc.Such appearance design makes rubber bits cleaner have decoration functions in work or study occasion.
