Description
Technical field
The utility model relates generally to English teaching technical field, more particularly to a kind of English teaching chalkboard eraser.
Background technology
Chalkboard eraser is the teaching aid commonly used in process of English teaching, for wiping the chalk dust on blackboard, prior art
In, a kind of chalkboard eraser, including housing and hair are disclosed in the Chinese utility model patent of Patent No. 201020668340.9
Brush, hairbrush is installed to be provided with hole, housing with the one side on housing, being provided with the housing of hairbrush and is correspondingly provided with fan with hole, with
Fan is connected with motor, power supply in turn, and fan swicth is provided with the upper surface of housing.The chalkboard eraser structure that the utility model is provided
Simply, practical, good absorbing effect avoids chalk bits and flies everywhere, protects the health of child.
But, the chalkboard eraser in above-mentioned patent, fan dust absorbing structure despite the provision of, but its suction port is provided in hairbrush
Bottom, in order that during chalk dust can fall to suction port, the ratio that the gap between hairbrush can be stayed is larger so that its absorption
Power is not strong, and more chalk dusts can descend slowly and lightly from the surrounding of hairbrush, if using sponge, although sponge is than the absorption affinity of hairbrush
By force, but because sponge occupied area is larger, can cause the partial occlusion of suction port, cause chalk dust also to be difficult to drop into dust suction
In mouthful.
The content of the invention
In view of the shortcomings of the prior art, the utility model aims to provide a kind of English that can effectively lift pick-up performance
Teaching chalk is wiped.
To achieve the above object, the utility model provides following technical scheme：
A kind of English teaching chalkboard eraser, includes support, and the support includes two cross bars being parallel to each other, in institute
Powder baffle plate is connected between two cross bars stated, the support secures many and is parallel to each other above the powder baffle plate
Roller, the spongy layer for erasing the board is enclosed with the roller outer wall, the support includes outer surrounding baffle, the horizontal stroke
Bar is vertically connected on the side of the outer surrounding baffle, and being formed between the powder baffle plate and the outer surrounding baffle can accommodate powder
The space that pen ash is passed through, is further fixed on wind-tunnel in the support, and the wind-tunnel is located at the lower section of the powder baffle plate, the wind
Hole has transverse part and longitudinal direction portion, and the transverse part and longitudinal direction portion inside are interconnected, are formed with the two ends of the transverse part
Powder inlet, described longitudinal portion one end is vertically connected on the middle part of the transverse part, and the other end is formed with meal outlet, it is described go out powder
Fan is fixed with mouthful, powder groove is further fixed on the bracket, the wind-tunnel is located at the side of the fan, the powder
Groove is located at the opposite side of the fan；
Slanting baffle is connected with the outer surrounding baffle, acute angle folder is formed between the slanting baffle and the outer surrounding baffle
Angle.
As improvement of the present utility model, through hole is offered on the outer surrounding baffle, the through hole faces described
Powder inlet.
Used as further improvement of the utility model, the support includes two over braces being parallel to each other, each
Root over brace correspond to the cross bar described in, and the over brace is located at the surface of the cross bar, in the horizontal stroke
Described roller is connected between bar support.
Compared with prior art, the utility model has the advantage of：There is provided spongy layer wipes chalk dust, relative to hair
Brush, absorption affinity is stronger, there is provided outer surrounding baffle and slanting baffle, can effectively block the chalk dust descended slowly and lightly from surrounding, makes its quilt
It is trapped among in the range of a fan can be adsorbed onto, in addition, by setting a wind-tunnel, while adsorption efficiency is improved,
Also allow for follow-up cleaning.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model embodiment English teaching chalk is wiped；
Fig. 2 is the internal structure schematic diagram of Fig. 1；
Fig. 3 is the structural representation of roller in Fig. 1.
Specific embodiment
The embodiment that the utility model English teaching chalk is wiped is described further referring to the drawings.
As shown in drawings, the present embodiment is a kind of English teaching chalkboard eraser, includes support 1, and support includes two
The cross bar 2 being parallel to each other, is connected with powder baffle plate 3 between two cross bars, and powder baffle plate undulate is set, with multiple pleats
Drawn grain, while increased with chalk dust contact area, is compared to slab construction, and the fold groove in fold face can be to falling
Chalk dust on powder baffle plate plays temporary effect, prevents chalk dust from being flown away everywhere on powder baffle plate.
Above-mentioned support is provided with two over braces 11 being parallel to each other, each cross bar branch in the top of powder baffle plate
Frame correspond to the cross bar described in, and the over brace is located at the surface of the cross bar, the over brace it
Between secure many rollers 4 being parallel to each other, the spongy layer 5 for erasing the board is enclosed with roller outer wall, be compared to existing
There is the hairbrush that documents in technology are used, the absorption affinity of sponge is stronger, and the airborne dust produced in wiping chalk is less（Hair
Brush is to be stirred chalk dust in wiping chalk ash, therefore the airborne dust for causing is more, and sponge is then a kind of absorption）.
The support includes outer surrounding baffle 6, and the cross bar is vertically connected on the side of the outer surrounding baffle, in the powder
Being formed between last baffle plate and the outer surrounding baffle can accommodate the space that chalk dust is passed through, and wind-tunnel is further fixed in the support
7, the wind-tunnel is located at the lower section of the powder baffle plate, and the wind-tunnel has transverse part 71 and a longitudinal direction portion 72, the transverse part with
Longitudinal portion inside is interconnected, and powder inlet 711 is formed with the two ends of the transverse part, and described longitudinal portion one end is vertically connected on
The middle part of the transverse part, the other end is formed with meal outlet 721, and wind-tunnel integral material is made of metal, and chalk dust cannot be from
Penetrated on the side wall of wind-tunnel.Fan 8 is fixed with the meal outlet, fan is connected to battery（Not shown in figure）, by battery
Drive fan to rotate, when fan is rotated, the fixed air-flow for flowing to can be produced in wind-tunnel, compared in the prior art directly by
The technology of fan dust suction, wind-tunnel serves a kind of conflux and the effect being oriented to, and can produce the air-flow and absorption effect of fixed flow direction
Rate is higher（Can directly be disturbed by convection outside air by fan dust suction, and wind-tunnel can be carried out effectively to extraneous air
Isolation）,
Powder groove 9 is also removably secured by way of clamping on the bracket, the wind-tunnel is located at the wind
The side of fan, the powder groove is located at the opposite side of the fan, and the chalk dust that fan is adsorbed can be entered into powder groove
Storage, when cleaning is needed, it is only necessary to outwell internal powder by powder groove is pulled down.
Slanting baffle 10 is connected with the outer surrounding baffle, acute angle is formed between the slanting baffle and the outer surrounding baffle
Angle.Slanting baffle further can block the chalk dust of flare,
Through hole 61 is offered on the outer surrounding baffle, the through hole faces described powder inlet, slanting baffle powder instantly
