It can be flowed into by gap in water leg 180.
It is pointed out that in other embodiment of the present utility model, the quantity of bar shaped blackboard eraser 140 can also be two
Or two or more.
As in Figure 3-5, bar shaped blackboard eraser 140 includes two connecting portions 141 and bar shaped blackboard eraser body 144, two connecting portions
141 are respectively arranged at the opposite end of bar shaped blackboard eraser body 144.Connecting portion 141 passes through nut 160 with bar shaped blackboard eraser body 144
Realization is detachably connected, and the outer wall for the connection end that connecting portion 141 is connected with bar shaped blackboard eraser body 144 is provided with external screw thread 170, bar
The outer wall for the connection end that shape blackboard eraser body 144 is connected with connecting portion 141 is also equipped with external screw thread 170, and the inwall of nut 160 is set
There is internal thread, the internal thread of external screw thread 170 and the inwall of nut 160 cooperates so that bar shaped blackboard eraser body 144 and connecting portion
141 are detachably connected, and screw on nut 160 realizes the connection or dismounting of bar shaped blackboard eraser body 144 and connecting portion 141.
As shown in Figure 4 and Figure 6, connecting portion 141 has buckling parts 142, buckling parts 142 with the connection end that slide rail 130 is connected
On offer mating groove 143, the cavity of the part of the mating groove 143 away from slide rail 130 is more than the opening of mating groove 143, slide rail
130 connecting sides being connected with connecting portion 141 offer groove, be provided with the groove be engaged with the shape size of mating groove 143 it is convex
Portion 131, in the installation process of blackboard 100 easy to clean, connecting portion 141 is fastened in slide rail 130 by buckling parts 142
The connection of bar shaped blackboard eraser 140 and slide rail 130 is realized on convex portion 131.
It is pointed out that in other embodiment of the present utility model, connecting portion 141 is slidably connected with slide rail 130
It can also be connected mode that chute is connected with roller etc..
As shown in Fig. 3, Fig. 5 and Fig. 7, bar shaped blackboard eraser body 144 includes rag 148, support member 146 and 8 buckling pieces
145.The opposite end of support member 146 is connected with two connecting portions 141 respectively.Buckling piece 145 is arranged at the outer of support member 146
Wall, it is interlocked with support member 146, an end set of buckling piece 145 is in writing of the support member 146 away from blackboard body 110
The side of plate face, and be rotatablely connected with support member 146.Using the side of writing plate face of the support member 146 away from blackboard body 110 as
Front, then buckling piece 145 close to the end set of the writing plate face of blackboard body 110 in the side of support member 146, support member
146 side is provided with projection 147, and buckling piece 145 realizes that it is mutual with support member 146 by being cooperated with projection 147
Fasten.Rag 148 is wrapped in support member 146 close to the side of the writing plate face of blackboard body 110, and the end of rag 148 is set
It is placed between support member 146 and buckling piece 145, rag 148 is in contact with the writing plate face of blackboard body 110.Rag 148 passes through
Being fastened and connected of buckling piece 145 and support member 146 realizes its being detachably connected with support member 146.
Being detachably connected so that be easily changed using rag 148 after a while for rag 148 and support member 146, is changed
Under the cleaning of rag 148 dry later and recirculate use again.
It is pointed out that in other embodiment of the present utility model, the quantity of buckling piece 145 is even number, according to
Production using needs, the quantity of buckling piece 145 with can slightly be adjusted；Meanwhile in other embodiment of the present utility model, smear
The detachable connection of cloth 148 and support member 146, which can also be, is bolted directly to rag 148 in support member 146 using rope
On.
Bar shaped blackboard eraser body 144 also includes elastic insert 149, elastic insert 149 can use foam or sponge this
The cost of class is relatively low and flexible material is made, and elastic insert 149 is arranged between rag 148 and support member 146, support
Part 146 is provided with the holding tank (not shown) for accommodating elastic insert 149 close to the side of the writing plate face of blackboard body 110, smears
Cloth 148 is fully wrapped around by elastic insert 149.
The purpose for setting elastic insert 149 is, between increase bar shaped blackboard eraser 140 and the writing plate face of blackboard body 110
Pressure, simultaneously because its is flexible, therefore it will not make it that bar shaped blackboard eraser 140 is excessively raw during blackboard wiping body 110
The writing plate face of blackboard body 110 is caused to be difficult to clean firmly.
The course of work of the blackboard 100 easy to clean can manually be controlled, can also be by installing motor etc.
The blackboard 100 for making it easy to cleaning works automatically, can also be remotely controlled the work of blackboard 100 easy to clean by installing remote control etc.
Make.
, it is necessary to which the writing plate face to blackboard body 110 carries out thorough cleaning after one day End-of-Course in classroom, it is easy to clear
The course of work of clean blackboard 100 approximately as：
Open control water inlet pipe 151 intake water intaking valve so that flushing water through spray water branch pipe 152 flow out, flushing water along
Under the clipboard surface current of blackboard body 110, now cause bar shaped blackboard eraser 140 along the side-to-side movement blackboard wiping body 110 of slide rail 130
Writing plate face, the water flowed out from water spray branch pipe 152 finally flows into water leg 180 and discharged through discharge outlet 181, treats blackboard body
After 110 writing plate face cleans up, water intaking valve is closed, makes it when bar shaped blackboard eraser 140 is moved to the edge of blackboard body 110
Stop motion.
In summary, the water spraying mechanism 150 of blackboard 100 easy to clean and the matching design of blackboard eraser mechanism 120 can incite somebody to action
The writing plate face of blackboard body 110 is cleaned cleaner, and the cleaning process is simple to operate can effectively save human cost
With the working time of cleanup crew；And the neat and tidy for being designed to be effectively ensured ground of water leg 180, while be also avoided that
Because of excess surface water and caused by security incident；The design for disassembly and rag 148 of connecting portion 141 and bar shaped blackboard eraser body 144 with
The rag 148 that the design for disassembly of support member 146 enables to be used for multiple times is easy to unpick and wash replacing；Elastic insert 149 is set
Put so that the writing plate face of blackboard body 110 is wiped cleaner by bar shaped blackboard eraser 140.
The present embodiment additionally provides a kind of tutoring system, and the tutoring system is provided with above-mentioned blackboard 100 easy to clean,
