Optionally, a plurality of dust suction holes are formed in the dust suction pipeline.
Optionally, the upper end of the blackboard body is provided with a guard bar, and the guard bar is connected with a lighting device.
Optionally, the lighting device includes a lighting lamp, a power supply and a switch; the illuminating lamp is embedded in the guard bar, and the power supply and the switch are arranged on the side edge of the blackboard body.
Optionally, the illuminating lamp is a tubular illuminating lamp.
Optionally, the length-width ratio of the blackboard body is 4: 1-6: 1.
According to the specific embodiment provided by the invention, the invention discloses the following technical effects: the novel teaching blackboard disclosed by the invention has the advantages that dust falls into the dust suction pipeline in the wiping process, and then the dust collector is started to suck the dust, so that the content of the dust in the air is reduced.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without inventive exercise.
Fig. 1 is a schematic structural diagram of a novel teaching blackboard according to an embodiment of the present invention.
Description of the symbols: 1-blackboard body, 2-sliding track, 3-blackboard eraser, 4-dust absorption pipeline, 5-telescopic hose, 6-dust collector, 31-handle and 41-dust absorption hole.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention aims to provide a novel teaching blackboard which is used for reducing dust generated in the blackboard erasing process.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The first embodiment is as follows:
as shown in fig. 1, a novel teaching blackboard includes: blackboard body, blackboard eraser 3 and dust extraction. The length-width ratio of the blackboard body 1 is 4: 1-6: 1. The blackboard comprises a blackboard body 1 and is characterized in that the upper end and the lower end of the blackboard body 1 are respectively provided with a sliding rail 2, and a blackboard eraser 3 is arranged between the sliding rails 2 in a sliding manner. The blackboard eraser 3 comprises a brush hair, a eraser shell and a handle 31. The erasing hair is arranged on one surface of the erasing shell contacted with the blackboard body 1, and the handle 31 is arranged in the middle of the erasing shell. When the blackboard is wiped, the blackboard eraser can quickly erase writing only by pulling down the blackboard eraser from one end of the blackboard body and pulling down the other end of the blackboard eraser, the use is convenient, the handle is arranged in the middle, the left and right push-pull is convenient to realize, the stress is uniform, and the erasing effect is cleaner.
The dust suction device comprises a dust suction pipeline 4, a telescopic hose 5 and a dust collector 6. The dust absorption pipeline 6 is arranged at the lower end of the blackboard body 1, and a plurality of dust absorption holes 41 are formed in the dust absorption pipeline and used for containing powder generated by the blackboard eraser 3 when the blackboard is erased. The dust collector 6 is connected with the dust collection pipeline 4 through the telescopic hose 5 and is used for sucking away the powder in the dust collection hole 41.
When the blackboard eraser is used for erasing a blackboard, a power supply is switched on to start the dust collector, most of dust generated by erasing the blackboard is absorbed, and the content of dust in the air is greatly reduced.
Example two:
different from the first embodiment, the upper end of the blackboard body 1 is further provided with a guard bar (not shown in the figure), and the guard bar is connected with a lighting device (not shown in the figure). The lighting device comprises a lighting lamp, a power supply and a switch; the illuminating lamp is embedded in the guard bar, and the power supply and the switch are arranged on the side edge of the blackboard body. The illuminating lamp is a tubular illuminating lamp. The invention adopts the lighting device to concentrate the light on the blackboard, so that the content display on the blackboard is clearer, and the tubular lighting lamp can better ensure the relative uniformity of the light.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The principles and embodiments of the present invention have been described herein using specific examples, which are provided only to help understand the method and the core concept of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
