Abstract
The utility model discloses a blackboard eraser with a dust collector. An aim of the utility model is to settle a technical problem of dust scattering when the blackboard eraser is used. The blackboard eraser is mainly composed of the following components: an eraser body, a housing, a battery placement place, a small-size dust collector, a dust storage box, an induction switch and a dust suction inlet. The utility model is characterized in that: the small-size dust collector is designed in the blackboard eraser; and the small-size dust collector is connected with the eraser body through the dust suction inlet. As the technical is adopted for the blackboard eraser of the utility model, the blackboard eraser has the following advantages: collecting the dust of the chalk, preventing scattered dust, and effectively preventing health damage of the teacher and the student by chalk dust suction.
Description
Technical field
The utility model relates to a kind of blackboard eraser, especially a kind of blackboard eraser that can absorb the band dust catcher of dust automatically.
Background technology
At present, when ordinary blackboard eraser erases the board, equal phenomenons that can cause powder to exist everywhere, this is having a strong impact on teachers and students' health, though some dust-proof blackboard erasers are also arranged, all because DeGrain or be inconvenient to use and do not popularized, problem is not well solved so far.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, blackboard eraser that can absorb the band dust catcher of dust automatically.
A kind of blackboard eraser of the present utility model with dust catcher, its objective is to solve the technical problem that dust flies upward easily when using blackboard eraser everywhere, mainly form by rub body, shell, battery lay down location, Small-sized suction cleaner, dust case, inductive switch and suction port.It is characterized in that: in the blackboard eraser indoor design Small-sized suction cleaner is arranged, link to each other with rub body by suction port; The design of blackboard eraser right side has inductive switch, in the blackboard eraser indoor design battery rest area is arranged.
Beneficial effect: designed Small-sized suction cleaner in a kind of blackboard eraser technical scheme of the present utility model, the dust that is adsorbed on the rub body can have been transferred in the subsidiary dust case during use, the temporary transient storage with dust catcher; Simultaneously, design inductive switch in this technical scheme, can respond to automatically and start working in use, better solved the problem that dust flies upward when erasing the board everywhere.
Description of drawings
Fig. 1 is a kind of wiping blackboard structure schematic diagram with dust catcher of the utility model embodiment.
Fig. 2 is the side structure schematic diagram of a kind of blackboard eraser with dust catcher of the utility model embodiment.
The specific embodiment
The explanation of mark among the figure: rub body 1, shell 2, battery lay down location 3, Small-sized suction cleaner 4, dust case 5, inductive switch 6, suction port 7.
A kind of blackboard eraser with dust catcher shown in Figure 1 is made up of rub body 1, shell 2, battery lay down location 3, Small-sized suction cleaner 4, dust case 5, inductive switch 6 and suction port 7.The first half design in blackboard eraser inside has battery rest area 3, in the design of the inside of blackboard eraser the latter half Small-sized suction cleaner 4 is arranged, the left side has by suction port 7 and is connected with rub body 1, and the design of blackboard eraser shell 2 right sides has inductive switch 6, links to each other with Small-sized suction cleaner 4 with battery rest area 3 by lead.
In use, grasp the position of blackboard eraser inductive switch 6, circuit can be responded to and connect to blackboard eraser, Small-sized suction cleaner 4 is just started working, so when erasing the board, be adsorbed on dust on the rub body 1 and will be transferred to dust case 5 the insides by Small-sized suction cleaner 4 and go, after using a period of time, dust case 5 bonnets are opened, poured out dust and can continue to use.
