Accompanying drawing explanation
By reading the detailed description of non-limiting example being done with reference to the following drawings, it is more obvious that other features, objects and advantages of the present utility model will become:
The structural representation that Fig. 1 wipes for the Double-purpose blackboard providing according to the utility model, wherein, button is not pressed;
The structural representation when button that Fig. 2 wipes for the Double-purpose blackboard providing according to the utility model shown in Fig. 1 is pressed.
In figure: 1 is blackboard eraser main part, 11 is chimb, and 12 is boss, and 2 is lid, and 21 is water storage cavity, and 31 is button, and 32 is spring fitting portion, and 33 is back-moving spring, and 34 is connecting rod, and 35 is tank drain hole, and 4 is bristle, and 5 is water suction portion.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is elaborated.Following examples will contribute to those skilled in the art further to understand the utility model, but not limit in any form the utility model.It should be pointed out that to those skilled in the art, without departing from the concept of the premise utility, can also make some distortion and improvement.These all belong to protection domain of the present utility model.
As shown in Figure 1, the Double-purpose blackboard providing according to the utility model is wiped, and comprises blackboard eraser main part, lid, bristle, water suction portion, button, spring fitting portion, back-moving spring, connecting rod, tank drain hole and one way entrapped water valve.Wherein, between described lid and described blackboard eraser main part, removably connect, the tow sides of described blackboard eraser main part are respectively arranged with described bristle and described water suction portion, and the one side that described blackboard eraser main part is provided with described bristle is also provided with lid assembly connection portion.Described lid comprises water storage cavity, the end face of described water storage cavity is provided with installing hole, described button is installed in described installing hole, the bottom of described button connects described spring fitting portion, described back-moving spring is connected between the bottom and the bottom surface of described water storage cavity of described spring fitting portion, the two ends of described connecting rod connect respectively between the bottom and described tank drain hole of described spring fitting portion, and the bottom surface of described water storage cavity is provided with osculum.Described one way entrapped water valve is arranged at the chamber wall of described water storage cavity.
The utility model is respectively arranged with bristle and towel on the two sides of blackboard eraser main part, can select easily different blackboard cleaning modes, and lid can be removably installed in the two sides that backboard is wiped main part, thereby lid can be installed on to the one side that blackboard eraser main part is provided with bristle when using towel, prevent that chalk dust on bristle from shaking off and preventing that bristle from pricking the hand, and towel easy to use.Further, by control button, can also add in time water and can control well the wettability of towel for towel, and can not leak when not using.
In a preference of the present embodiment, described tank drain hole be shaped as truncated cone-shaped.The radius of described tank drain hole end face is less than the radius of bottom surface.Described button is positioned at the central position of described water storage cavity end face.Described water suction portion is towel.Described lid assembly connection portion is boss, and described bristle is connected in described blackboard eraser main part by described boss.The one side that described blackboard eraser main part is provided with described water suction portion is also provided with chimb.And change in example at one, described towel can be changed to sponge.
