Design a kind of novel dust-free blackboard that is suitable for English professional teaching, it comprises the board body that is used for writing font, is used for the frame that this board body is fixedly arranged; The extension board protruding from the rear board, the board body is stuck in the four extension boards around the rear board, and there is an interval between the board body and the rear board; the top of the board body and the The bottom is respectively provided with a number of dust suction holes, the dust suction holes arranged on the top and bottom of the board are arranged horizontally at equal intervals, and two horizontally arranged in the interval between the board and the rear board The suction pipes at the top of the board communicate with the suction pipes above through conduits; the suction holes at the bottom of the board also communicate with the suction pipes below through conduits; The collecting pipe connected with the two suction pipes, the negative pressure pump connected with the other end of the collecting pipe, and the bag filter connected with the air outlet of the negative pressure pump; the extension of the top and bottom of the plate body A dust guide plate with an arc-shaped end face is also arranged on the board.

U-shaped slots are respectively provided on the inner side walls of the four extension plates around the outer frame, and the ends around the board body are respectively located in the U-shaped slots on the corresponding extension plates.

Both sides of the top end of the board are respectively connected to the inner wall of the U-shaped slot through anti-vibration pads.

The shockproof pad is a flexible rubber pad.

Several LED lamp beads for irradiating light to the board body are also arranged on the inner surface of each dust guide board.

The beneficial effects of the utility model are:

In the application, the blackboard of this design can firstly suck away the dust generated when writing or erasing, so as to avoid the phenomenon of environmental pollution and damage to personal health caused by it falling indoors. Secondly, the negative pressure pump of this design It can be set outdoors without affecting normal teaching activities; moreover, this design can collect dust through the use of bag filter, which is convenient for recycling and avoids the risk of secondary pollution; The vibration generated when the suction pipe is working is eliminated, and the problem of vibration caused by the suction pipe to the plate body is avoided.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment 1: A kind of novel dust-free blackboard that is applicable to the teaching of English major, see Fig. 1, Fig. 2; It comprises the board body 2 that is used for writing font, is used for the outer frame that this board body 2 is fixedly arranged; This In the design, the outer frame includes a rear panel 10, an extension panel 1 protruding from the rear panel 10 around the rear panel 10, the panel body 2 is stuck in the four extension panels 1 around the rear panel, and the There is an interval between the board body 2 and the rear board 10; further, this design is also provided with a number of suction holes 4, 5 on the top and bottom of the board body 2 respectively, which are arranged on the board body 1 The suction holes 4 and 5 on the top and bottom are arranged horizontally at equal intervals, and two suction pipes 8 and 9 arranged laterally are also arranged in the interval between the board body 2 and the rear board 10, Each dust suction hole 4 positioned at the top of the plate body 2 communicates with the suction pipe 8 positioned above through the conduit 6; each dust suction hole 5 positioned at the bottom of the plate body 2 also communicates with the suction pipe 9 positioned below through the conduit 7; It includes a collection pipe 15 with one end in communication with the two suction pipes 8 and 9 , a negative pressure pump 16 in communication with the other end of the collection pipe 15 , and a bag filter 17 in communication with the air outlet of the negative pressure pump 16 .

Further, in this design, arc-shaped dust guide plates 11 and 12 are also provided on the extension plates at the top and bottom of the board body 2, and dust guide plates 11 and 12 are also provided on the inner surfaces of each dust guide plate 11 and 12. There are several LED lamp beads 14, 13 for illuminating light to the board body. Further, this design is also provided with U-shaped slots on the inner side walls of the four extension plates around the outer frame, and the ends around the board body 2 are respectively located on the U-shaped slots on the corresponding extension plates.
