The dust suction port 71 is arranged alternately with the lower end of the electrostatic attraction plate 9 , that is, there is a certain gap.
为保证使用效果，所述的毛刷4固定在毛刷固定框5内，毛刷固定框5通过第一连接螺栓10装在吸尘口71下方的箱体底面上。In order to ensure the use effect, the brush 4 is fixed in the brush fixing frame 5, and the brush fixing frame 5 is installed on the bottom surface of the box below the dust suction port 71 through the first connecting bolt 10.
所述的海绵吸尘结构8包括竖向支撑板81，竖向支撑板81中心的上部和下部分设置有向前水平伸出的中支撑柱83，竖向支撑板81两侧的上部和下部分设置有向前水平伸出的侧支撑柱84，中支撑柱83与两侧的侧支撑柱84之间分别设置有第一海绵板85a和第二海绵板85b，第一海绵板85a有呈平行均布的多个，其平行方向与风扇3的吹风方向呈非平行设置，第二海绵板85b与第一海绵板85a数量相等且一一对应，二者呈对称设置，相邻两第一海绵板85a之间的间隙构成第一风道，相邻两第二海绵板85b之间的间隙构成第二风道，第一风道与第二风道一一对应且相连通，构成吸尘风道86，吸尘风道86的进风端86a与静电吸引板9正对，出风端86b与除尘箱的开口端74正对。The sponge dust collection structure 8 includes a vertical support plate 81, the upper and lower parts of the center of the vertical support plate 81 are provided with a middle support column 83 extending horizontally forward, and the upper and lower parts of the vertical support plate 81 on both sides A side support column 84 protruding horizontally forward is partially provided, and a first sponge board 85a and a second sponge board 85b are respectively arranged between the middle support column 83 and the side support columns 84 on both sides, and the first sponge board 85a has a A plurality of parallel evenly distributed, its parallel direction is non-parallel to the blowing direction of the fan 3, the second sponge board 85b is equal in number to the first sponge board 85a and corresponds to each other, the two are symmetrically arranged, and the adjacent two first sponge boards The gap between the sponge boards 85a constitutes the first air passage, the gap between two adjacent second sponge boards 85b constitutes the second air passage, and the first air passage and the second air passage are one-to-one corresponding and communicated to form a dust suction system. The air duct 86, the air inlet end 86a of the dust suction air duct 86 is directly opposite to the electrostatic attraction plate 9, and the air outlet end 86b is directly opposite to the opening end 74 of the dust removal box.
所述中支撑柱83远离竖向支撑板81的一端设置有定位块82，箱体7内设置有与定位块82相对应的定位槽72，定位块82卡装在定位槽72内，构成海绵吸尘结构与箱体之间的安装连接结构；所述盖板上设置有注水凸棱6，注水凸棱6内或注水凸棱下方的箱体顶板内设置有导流通道62，注水凸棱6上开有与导流通道62相连通的注水口61，导流通道62下部开有与除尘箱内腔相连通的多个出水孔63，出水孔63均位于第一海绵板85a或第二海绵板85b的正上方，构成第一海绵板和第二海绵板的注水结构，注水后使第一海绵板和第二海绵板处于潮湿状态，从而增加其对粉尘的主动吸附能力。所述的注水口61位于注水凸棱6的中心，出水孔63的孔径由中心向两侧递增，这使得水流在刚进入注水口的时候不会全部随着最近的注水口全部流出，更多的水滞留在导流通道内部，并且滞留量越来越多，最后到达离中心最远的注水口，流向下方的海绵板上。且两侧两相邻出水孔之间的导流通道底面呈由内向外、由高至低倾斜设置，且各个坡度由中心向外侧呈逐渐增加，在重力作用下水流在导流通道中更多的流向距离中心最远的注水口，加大最远注水口的水的流量，使得水流最终均匀地经过注水口流向位于导流孔下方的海绵板。The end of the middle support column 83 away from the vertical support plate 81 is provided with a positioning block 82, and the box body 7 is provided with a positioning groove 72 corresponding to the positioning block 82, and the positioning block 82 is clamped in the positioning groove 72 to form a sponge The installation and connection structure between the dust suction structure and the box; the cover plate is provided with a water injection rib 6, and a diversion channel 62 is arranged inside the water injection rib 6 or in the top plate of the box below the water injection rib, and the water injection rib 6 is provided with a water injection port 61 that communicates with the diversion channel 62, and the lower part of the diversion channel 62 is provided with a plurality of water outlet holes 63 that communicate with the inner cavity of the dust removal box. The water outlet holes 63 are all located on the first sponge plate 85a or the second The water injection structure of the first sponge board and the second sponge board is formed directly above the sponge board 85b. After water injection, the first sponge board and the second sponge board are in a wet state, thereby increasing their active adsorption capacity for dust. The water injection port 61 is located at the center of the water injection rib 6, and the aperture of the water outlet hole 63 increases from the center to both sides, which makes the water flow not all flow out with the nearest water injection port when it first enters the water injection port, more The water stagnated inside the diversion channel, and the stagnant amount is increasing, and finally reaches the water injection port farthest from the center, and flows to the sponge plate below. Moreover, the bottom surface of the diversion channel between two adjacent water outlet holes on both sides is inclined from the inside to the outside, from high to low, and each slope gradually increases from the center to the outside. Under the action of gravity, the water flow in the diversion channel is more Increase the flow of water at the farthest water injection port to the water injection port farthest from the center, so that the water flow finally flows evenly through the water injection port to the sponge plate located below the diversion hole.
所述箱体7侧壁上设置有与风扇3相对应的风扇安装孔73，风扇3固定装在风扇安装孔73内，除尘箱内设置有用于安装电池的电池安装槽76，电池安装槽76内装有用于风扇供电的电池。The side wall of the box body 7 is provided with a fan mounting hole 73 corresponding to the fan 3, the fan 3 is fixedly installed in the fan mounting hole 73, and the dust removal box is provided with a battery mounting groove 76 for installing a battery, and the battery mounting groove 76 Built-in battery for powering the fan.

本发明的使用情况是，在擦拭黑板时，毛刷首先擦去粉笔灰尘，同时使得粉尘通过毛刷之间的间隙被静电吸引板吸引进入吸尘箱的内部，同时，处在静电吸引板之间的粉笔粉末又会受到来风扇的风力作用，从而被引向海绵吸尘结构，海绵吸尘结构采用较薄的海绵板(片)制成，并且可以对海绵板注水，在潮湿状态下对粉尘进行主动吸附，且海绵吸尘结构的海绵板与风扇的吹风方向非平行设置，即存在一定的夹角，这样使得粉尘风与海绵板的接触面积变大，从而最大可能的吸收粉尘，与现有技术相比，本发明结构新颖独特，简单合理，体积小，重量轻，体积、重量均与平常常见的普通黑板擦没有太大差别，操作方便，随用随取，使用者可以像传统黑板擦一样使用本产品，而且带有吸尘清洁功能，使用静电和风扇结合的方式解决了现在擦拭粉尘过程中的乱飞现象，使用海绵(潮湿状态)吸收粉尘，降低了成本，提高了可靠性和可行性，可以更好的保护使用者的身体健康，使用方便，效果好，有良好的社会和经济效益。The use of the present invention is that when wiping the blackboard, the brush first wipes off the chalk dust, and at the same time, the dust is attracted by the electrostatic attraction plate through the gap between the brushes and enters the interior of the dust collection box. The chalk powder in between will be subjected to the wind force of the fan again, thereby be led to the sponge dust-absorbing structure, and the sponge dust-absorbing structure is made of thinner sponge board (sheet), and can be filled with water to the sponge board, in wet state Dust is actively adsorbed, and the sponge board of the sponge dust suction structure is not parallel to the blowing direction of the fan, that is, there is a certain angle, which makes the contact area between the dust wind and the sponge board larger, thereby absorbing dust to the greatest possible extent, and Compared with the prior art, the present invention is novel and unique in structure, simple and reasonable, small in size and light in weight. The volume and weight are not much different from common blackboard erasers. This product is also used for blackboard erasers, and it has the function of vacuuming and cleaning. The combination of static electricity and fans solves the random flying phenomenon in the process of wiping dust, and uses sponges (wet state) to absorb dust, which reduces costs and improves reliability. It can better protect the user's health, is convenient to use, has good effect, and has good social and economic benefits.
