Detailed description of the invention
Below in conjunction with drawings and Examples, set forth the utility model further.In the following detailed description, the mode only by illustrating describes some one exemplary embodiment of the present utility model.Undoubtedly, those of ordinary skill in the art can recognize, when not departing from spirit and scope of the present utility model, can revise by various different mode to described embodiment.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection domain of claim.
Embodiment:
As shown in Figure 1 to Figure 3, present embodiment discloses a kind of dust collecting 100, comprise dust catcher 300, its one end is connected with power source; Dust shield 110, one end of this dust shield 110 is connected with dust catcher 300; Pipeline 120, one end of this pipeline 120 is connected with above-mentioned dust shield 110; Dust-collecting cylinder 130, one end of this dust-collecting cylinder is connected with the other end of above-mentioned pipeline 120, and the other end of this dust-collecting cylinder is closed state.Like this, when carrying out wiping to blackboard, under the effect of power source, dust catcher enters duty, collected the dust that blackboard wiping produces by dust shield on the one hand, on the other hand by the dust that blackboard wiping produces, part is collected in dust-collecting cylinder under himself Action of Gravity Field, be collected in circulation set by the road in dust shield, the dust finally completed blackboard wiping produces is collected fully and effectively.
Dust shield 110, be check valve in the centre position of dust shield above-below direction, when dust catcher enters duty, this check valve enters opening, the dust that blackboard wiping produces is carried out comprehensive collection, when dust catcher enters off working state, above-mentioned check valve enters closed condition, like this, can effectively the dust of collection be left in dust shield, simultaneously, it is horn-like that class is preferentially arranged to by this dust shield, this dust shield comprises stub end and little head end, its little head end is for connecting neck 111, this connection neck is preferentially arranged to hollow tubular structure, above-mentioned dust catcher 300 is connected with dust shield by connecting neck, its stub end is provided with multiple cavernous structure, is preferentially set to circle, and this cavernous structure ordered arrangement is in dust shield stub end place, exactly because the setting of these cavernous structure features, makes the air circulation in dust shield more evenly smooth and easy.
Preferentially, this dust shield is set up in parallel as one or more, in the present embodiment, the quantity of dust shield is two, is effectively fixedly connected with between them by connecting plate 112 meanwhile, in order to promote the fixing stability of dust shield better, the downside of dust shield stub end is provided with fixed head 210, and this fixed head one end is connected with dust shield, and the other end is fixedly connected with blackboard body 200 stablely.
Pipeline 120, one end of this pipeline 120 is connected with above-mentioned dust shield 110, preferentially, be connected to the below of the check valve of dust shield above-below direction middle, the other end is connected with one end of dust-collecting cylinder, in order to the stability that lift line is fixing, above-mentioned pipeline arranges multiple clip 121, and pipeline is fixed on body of wall by these clips effectively.
Dust-collecting cylinder 130, one end that this dust-collecting cylinder is connected with above-mentioned pipeline is provided with rotatable valve plate 131, simultaneously, this valve plate is fixedly connected with the action button 132 making valve plate rotate motion, the adjustment to valve plate aperture in dust-collecting cylinder can be realized by action button, when the dust that blackboard wiping produces, part is collected in dust-collecting cylinder under himself Action of Gravity Field, operation aforesaid operations button, circulation by the road will by dust centralized collection in dust shield again, and the dust finally completed blackboard wiping produces carries out comprehensive collection.The other end of this dust-collecting cylinder is preferentially set to closed state, and meanwhile, the upper end of this dust-collecting cylinder is part non-closed state, is convenient to make part dust be collected in dust-collecting cylinder under himself Action of Gravity Field better.
The use procedure of the utility model embodiment is as follows:
When user will start blackboard wiping, start power source, dust catcher is made to enter duty, the check valve in dust shield is impelled to open, air evenly circulates swimmingly through the cavernous structure of dust shield stub end in dust shield, simultaneously, check whether the valve plate of dust-collecting cylinder and pipeline link is in closed condition, should it be preferentially made to keep closed condition, now, user can carry out wiping to blackboard, by dust shield, the dust that blackboard wiping produces is collected on the one hand, on the other hand by the dust of blackboard wiping generation, part is collected in dust-collecting cylinder under himself Action of Gravity Field, when user's blackboard wiping completes, operation action button makes valve plate enter opening, like this, circulation will by dust centralized collection in dust shield by the road, the dust finally completed blackboard wiping produces carries out comprehensive collection.
A kind of dust collecting that the utility model relates to, when carrying out wiping to blackboard, under the effect of power source, dust catcher enters duty, collected the dust that blackboard wiping produces by dust shield on the one hand, on the other hand by the dust that blackboard wiping produces, part is collected in dust-collecting cylinder under himself Action of Gravity Field, be collected in circulation set by the road in dust shield, the dust finally completed blackboard wiping produces is collected fully and effectively; Centre position because of dust shield above-below direction is check valve, when dust catcher enters duty, this check valve enters opening, the dust that blackboard wiping produces is carried out comprehensive collection, when dust catcher enters off working state, above-mentioned check valve enters closed condition, like this, can effectively leave in dust shield by the dust of collection; Stub end because of dust shield is provided with multiple cavernous structure, and this cavernous structure ordered arrangement, in dust shield stub end place, makes the air circulation in dust shield more evenly smooth and easy; The one end be connected with pipeline because of dust-collecting cylinder is provided with rotatable valve plate, simultaneously, this valve plate is fixedly connected with action button, the adjustment to valve plate aperture in dust-collecting cylinder can be realized by action button, and then make to be collected in dust in dust-collecting cylinder and be collected in dust shield in circulation set by the road; Because dust shield is set to one or more, effectively ensure the comprehensive collection of dust.
The foregoing is only the schematic detailed description of the invention of the utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
