上述实施例中,如图1、图4所示,前盖2和上盖4都通过连接螺钉13固定在外壳1上,并在前盖2与外壳1连接处设置有成型的填料密封14,以保证只有进尘口6一个进风口,进而增大吸尘风扇8的吸尘效果。填料密封14可以采用O型橡胶圈等。当擦拭毛毡5及板擦毛7磨损不能正常使用时,通过连接螺钉13可以进行拆卸更换。上盖4通过连接螺钉13可以打开,打开后可取出吸尘风扇8,并对吸尘风扇8以及滤网12进行清洁维护。In the above-mentioned embodiment, as shown in Fig. 1 and Fig. 4, both the front cover 2 and the upper cover 4 are fixed on the casing 1 by connecting screws 13, and a molded packing seal 14 is provided at the joint between the front cover 2 and the casing 1, To ensure that there is only one air inlet of the dust inlet 6, and then increase the dust collection effect of the dust suction fan 8. Packing seal 14 can adopt O type rubber ring etc. When wiping felt 5 and blackboard eraser wool 7 wear and tear and can't normally use, can disassemble and replace by connecting screw 13. The upper cover 4 can be opened by connecting screws 13, and the dust suction fan 8 can be taken out after opening, and the dust suction fan 8 and the filter screen 12 can be cleaned and maintained.
上述各实施例中,如图3所示,在粉尘收集仓11底部设置有排尘塞15,当粉笔灰收集到一定多时,可以打开排尘塞15将粉笔灰集中处理。In each of the above-mentioned embodiments, as shown in Figure 3, a dust discharge plug 15 is provided at the bottom of the dust collection bin 11, and when a certain amount of chalk dust is collected, the dust discharge plug 15 can be opened for centralized processing of the chalk dust.
上述各实施例中,如图1、图5所示,在上盖4上设置有排风口16,用于将吸尘风扇8吸入的气体排出外壳1内。In the above-mentioned embodiments, as shown in FIG. 1 and FIG. 5 , the upper cover 4 is provided with an air outlet 16 for exhausting the gas sucked by the dust suction fan 8 into the casing 1 .
上述各实施例中,如图1、图2所示,位于外壳1一侧侧壁上设置有用于控制电池工作的开关17。In the above-mentioned embodiments, as shown in FIG. 1 and FIG. 2 , a switch 17 for controlling the operation of the battery is provided on the side wall of the casing 1 .
综上所述,本实用新型在使用时,首先取下电池仓盖3,装入电池后再将电池仓盖3盖好,打开开关17,吸尘风扇8便开始转动。此时擦黑板上的粉笔字,粉笔字便会在擦拭毛毡5的擦拭作用下被擦掉,堆积产生的粉笔灰进一步被板擦外层的板擦毛7雾化后,在吸尘风扇8的吸力作用下,有粉笔灰及空气形成的气固两相流就被从进尘口6吸入曲折通道10,并在曲折通道10出口被滤网12过滤后,气体由排风口16排出,而粉笔灰却被过滤网12过滤住。当黑板擦完后,关闭开关17,吸尘风扇8停止转动,滤住的粉笔灰则被掉入粉尘收集仓11中。由于曲折通道10的密封作用,无论黑板擦如何颠倒倾斜,收集好的粉笔灰都不会被洒出来。当粉笔灰收集到一定多时,可以打开排尘塞15将粉笔灰倒出集中处理。In summary, when the utility model is in use, the battery compartment cover 3 is first taken off, the battery compartment cover 3 is covered after the battery is put into the battery, the switch 17 is opened, and the dust suction fan 8 starts to rotate. Now wipe the chalk characters on the blackboard, the chalk characters will be wiped off under the wiping effect of the wiping felt 5, and the chalk dust that accumulates to produce is further atomized by the blackboard eraser hair 7 of the blackboard eraser outer layer, and the suction of the dust suction fan 8 Under the action, the gas-solid two-phase flow formed by chalk dust and air is sucked into the zigzag passage 10 from the dust inlet 6, and after being filtered by the filter screen 12 at the outlet of the zigzag passage 10, the gas is discharged from the air outlet 16, and the chalk Ash is filtered by filter screen 12. After the blackboard was wiped, the switch 17 was closed, and the dust suction fan 8 stopped rotating, and the chalk dust filtered was dropped into the dust collection bin 11. Due to the sealing function of the tortuous channel 10, no matter how the blackboard eraser is tilted upside down, the chalk dust collected will not be spilled. When the chalk dust is collected to a certain amount, the dust discharge plug 15 can be opened and the chalk dust is poured out for centralized processing.
上述各实施例仅用于说明本实用新型,各部件的连接和结构都是可以有所变化的,在本实用新型技术方案的基础上,凡根据本实用新型原理对个别部件的连接和结构进行的改进和等同变换,均不应排除在本实用新型的保护范围之外。The above-mentioned embodiments are only used to illustrate the utility model, and the connection and structure of each component can be changed.
