Abstract
The utility model relates to a kind of blackboard chalk dust collection and treatment device, comprise the collection tank being arranged on blackboard lower end, the lower end, middle part of described collection tank is connected with chalk dust and concentrates box, this chalk dust concentrates the side of box to be connected with vacuum cleaner by flexible pipe, one end of this vacuum cleaner is connected with chalk dust reservoir bag, and the upper end of described collection tank is provided with side and is connected with long limit hinge inside the upper end of collection tank upper cover plate.The utility model structure is simple, and adopt the chalk dust sucking-off cleaning that dust catcher will drop in collecting box, use simple, cost is low, is not easy to damage.
Description
Technical field
The utility model relates to chalk dust collecting device field, particularly relates to a kind of blackboard chalk dust collection and treatment device.
Background technology
In school, blackboard and chalk are the most frequently used instruments, but chalk can produce a lot of chalk dusts after writing on blackboard, these chalk dust majorities can drop on the lower end of blackboard, cleaning is got up pretty troublesome, and be easy to make chalk dust dispersion suspension in atmosphere, can have an impact to the health of student.
The many complex structures of existing chalk dust collecting device, bulky, use noise large, because playing with of student is easily damaged, use cost is higher.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of blackboard chalk dust collection and treatment device, and structure is simple, and adopt the chalk dust sucking-off cleaning that dust catcher will drop in collecting box, use simple, cost is low, is not easy to damage.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of blackboard chalk dust collection and treatment device, comprise the collection tank being arranged on blackboard lower end, the lower end, middle part of described collection tank is connected with chalk dust and concentrates box, this chalk dust concentrates the side of box to be connected with vacuum cleaner by flexible pipe, one end of this vacuum cleaner is connected with chalk dust reservoir bag, and the upper end of described collection tank is provided with side and is connected with long limit hinge inside the upper end of collection tank upper cover plate.
Supplement as one of the present utility model, the bottom surface of described collection tank is the inclined-plane concentrating box symmetry relative to chalk dust low between the senior middle school of two ends, facilitates chalk dust to concentrate in box mobile set to chalk dust.
Supplement as another kind of the present utility model, described chalk dust concentrates one of box section to be horizontally installed with the joint pin be connected with flexible pipe, facilitates chalk dust to concentrate box to dock with vacuum cleaner.
Further, the cross section of described upper cover plate is wedge shape, its upper end is horizontal plane, lower surface is inclined-plane, its thickness being connected with one end of hinge is greater than the thickness of the other end, and when normal use, upper cover plate is in vertical state, chalk dust directly drops in collection tank, and the inclined-plane on upper cover plate facilitates chalk dust to tumble.
When upper cover plate covers, start vacuum cleaner and just chalk dust can be concentrated the chalk dust in box and collection tank to be all sucked in chalk dust reservoir bag;
Also can start vacuum cleaner when upper cover plate is in vertical state the chalk dust flown away above collection tank is all sucked.
Also flexible pipe can be pulled up from joint pin when vacuum cleaner work, by other dusts in other removing classrooms, position in the aligning classroom, one end of flexible pipe.
The utility model structure is simple, and adopt the chalk dust sucking-off cleaning that dust catcher will drop in collecting box, use simple, cost is low, is not easy to damage.

Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
As Figure 1-4, embodiment of the present utility model relates to a kind of blackboard chalk dust collection and treatment device, comprise the collection tank 1 being arranged on blackboard lower end, the lower end, middle part of described collection tank 1 is connected with chalk dust and concentrates box 2, this chalk dust concentrates the side of box 2 to be connected with vacuum cleaner 4 by flexible pipe 3, one end of this vacuum cleaner 4 is connected with chalk dust reservoir bag 5, and the upper end of described collection tank 1 is provided with side and is connected with long limit hinge inside the upper end of collection tank 1 upper cover plate 6.
The bottom surface of described collection tank 1 is the inclined-plane concentrating box 2 symmetry relative to chalk dust low between the senior middle school of two ends, facilitates chalk dust to concentrate in box 2 mobile set to chalk dust.
Described chalk dust concentrates one of box 2 section to be horizontally installed with the joint pin 7 be connected with flexible pipe 3, facilitates chalk dust to concentrate box 2 to dock with vacuum cleaner 4.
The cross section of described upper cover plate 6 is wedge shape, its upper end is horizontal plane, lower surface is inclined-plane, its thickness being connected with one end of hinge is greater than the thickness of the other end, when normal use, upper cover plate 6 is in vertical state, and chalk dust directly drops in collection tank 1, and the inclined-plane on upper cover plate 6 facilitates chalk dust to tumble.
Embodiment 1
When upper cover plate 6 covers, start vacuum cleaner 4 and just chalk dust can be concentrated the chalk dust in box 2 and collection tank 1 to be all sucked in chalk dust reservoir bag 5;
Embodiment 2
Also can start vacuum cleaner 4 when upper cover plate 6 is in vertical state the chalk dust flown away above collection tank 1 is all sucked.
Embodiment 3
Also flexible pipe 3 can be pulled up from joint pin 7, by other dusts in other removing classrooms, position in the aligning classroom, one end of flexible pipe 3 time vacuum cleaner 4 works.
The utility model structure is simple, and adopt the chalk dust sucking-off cleaning that dust catcher will drop in collecting box, use simple, cost is low, is not easy to damage.
