12 connections.
Guide rail 18 is installed in the upper and lower ends of blackboard 17, the both ends of mobile bar 1 are slidably connected by pulley and guide rail 18, are moved
Brush body 2 is housed in lever 1, simple erasing effect is just realized while mobile, servo electricity can be controlled by switch button
Startup, pause and the positive and negative rotation of machine 12 disclosure satisfy that teacher attends class a variety of clear wiping demands, selectivity to control the range wiped clearly
It is not unique, highly practical, easy to operate, flexibility is high；If blackboard word is more, and plate body does not moisten, the effect to erase the board
Can be poor, the dust that blackboard leaves is more, can influence writing next time.And water injector can spray water by water spout 3
Mist moistens blackboard, assists other devices preferably to clean blackboard, water injector is by water tank 4, water pump 5, water-supply-pipe 6, water spray
Mouths 3 etc. form, and are integrated on bar.Wherein water tank is usually the plastic cistern of 0.2-0.5L, water pump be a kind of miniature electric from
The washings of water tank are transferred to water spout by heart pump by water pump, and washings are divided by the squeezing action through 2~4 water spouts
Tiny jet stream sprays to blackboard；The existing mode of erasing the board will produce more dust, and take dust exhaust apparatus that can absorb clearly
The dust generated when clean blackboard solves harm of the dust to teachers and students.The device is mainly by dust absorbing box 7, conduit 8, dust suction electricity
Machine, air duct impeller 9 form, and are integrated on bar.After unlatching, dust sucting motor is rotated with certain rotating speed, makes the 9 inside production of air duct impeller
Raw negative pressure, inlet scoop sucks dust under inside and outside differential pressure effect, absorbs in the removable dust absorbing box in 1 end of mobile bar 7
In；Drying unit can the blackboard body that is moistened by water injector of flash baking, achieve the effect that wipe i.e. use, the device mainly by
Wind turbine 10, tuyere 11, heating wire are dried, is integrated on bar.After unlatching, drying wind turbine 10 rotates, and air is sucked from air inlet, shape
At air-flow blown out again by tuyere 11, air by when, the heating wire energization heating in the tuyere 11 blows out hot wind, to
Realize drying function；
Dust suction, water spray and drying unit are added in mobile bar 1, can be completed at the same time and be erased the board, recycle dust, profit
The functions such as wet and drying blackboard so that blackboard wipe clean integrates clear wiping, water spray, dust suction, drying multiple functions, realizes integrally
Change so that blackboard wipe clean can be individually installed on original old-fashioned blackboard, greatly reduce teaching fund.
It is further used as preferred embodiment, the water spout 3 is equipped with several, the water spout 3 described in several
It is evenly arranged in the side wall of mobile bar 1.According to the size of blackboard, the different water spout 3 of quantity and different spacing are set, with
The movement of guide rail 18 ensures that the water body that the water spout 3 on channel washer sprays can moisten entire blackboard 17.
It is further used as preferred embodiment, the rectangular in cross-section shape of the mobile bar 1, the brush body 2 is cut
The arched shape in face, is equipped with velcro 14 between the brush body 2 and mobile bar 1, the brush body 2 passes through velcro 14 and movement
The side wall of bar 1 connects.The arched shape in section of brush body 2 makes brush body 2 and the contact of blackboard 17 even closer, and cleaning effect is more
It is good, while the arched shape in section of brush body 2 and the wall surface of blackboard 17 form dust slot so that for brush body 2 in clear wipe, dust can heap
Product absorbs in the dust slot on 2 both sides of brush body, then by dust exhaust apparatus；Brush body 2 is connected by the side wall of velcro 14 and mobile bar 1
It connects, the main replacement for being convenient for brush body 2.
It is further used as preferred embodiment, the brush body 2 is made of sponge material.Sponge material cleaning effect
More preferably, adsorption capacity is strong, and deformation is restorative good, long lifespan.
It is further used as preferred embodiment, top, the lower part of the mobile bar 1 are respectively connected with adjusting bracket 15, institute
The pulley stated connects with 15 axis of adjusting bracket, and the mobile bar 1 is slidably connected with adjusting bracket 15, and the adjusting bracket 15 is equipped with locking
Mechanism 16, the retaining mechanism 16 realize positioning of the mobile bar 1 on adjusting bracket 15.For a long time using can cause brush body 2 with
There is gap in the contact of blackboard 17, and wipe clean just loses the function of wiping clearly, is slidably connected by mobile bar 1 and adjusting bracket 15, can
Mobile bar 1 is adjusted at a distance from blackboard 17, keeps the abutting of brush body 2 and blackboard 17, while also being provided with retaining mechanism 16 to movement
Bar 1 carries out locking positioning, increases the regulatory function of wipe clean, improves wipe clean applicability and practicability.
This equipment is available there are two types of pattern is wiped clearly simultaneously, and respectively common clear wiping pattern wipes clearly pattern with depth.It is general
The characteristics of it is to adapt to the demand that teacher repeatedly erases the board in a class to lead to clear wiping pattern, this pattern is quick, and can be direct
By switch 13 position wiped clearly is determined to drive mobile bar 1 come the motion mode of control servomotor 12, it can be effective
Improve classroom efficiency；Depth, which wipes clearly pattern and is then applied to remove (or the one day) blackboard of finishing class per class to repeatedly use, to be left
Dust trace, for the pattern along with water injector and drying unit, feature is being capable of deep clean blackboard.Teacher being capable of key reality
Existing depth clears up blackboard, specific as follows：(1) lower switch 13 is pressed, the water spout 3 on bar sprays water mist, passes through guide rail 18
It is mobile, monoblock blackboard 17 can be moistened, meanwhile, it also realizes clear wiping during water spray and absorbs dust function.(2) cleaning is completed
After blackboard, you can realize drying function by drying unit.Compared with existing single technology, we can accomplish to collect clear wiping,
Water spray, dust suction, drying multiple functions can select clear wiping region, selective not unique, practicability in one according to actual conditions
By force, easy to operate, flexibility is high.
The better embodiment of the present invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make various equivalent modifications or be replaced under the premise of without prejudice to spirit of that invention
It changes, these equivalent modifications or replacement are all contained in the application claim limited range.
