Description
Technical field
The utility model relates to a kind of improvement of moistening blackboard eraser, specifically the moistening blackboard eraser of a kind of rod-type.
Background technology
At present, the unit such as school, office is in teaching and training process, the blackboard eraser used, be made up of felt and fixed head, present blackboard eraser has the chalk foam under wiping, contaminated environment, and harm teachers and students' is healthy, for overcoming the above problems, somebody have studied moistening rotating blackboard eraser, the patent No. 201120072510.1, though this patent can overcome the above problems, but also there is following deficiency, one when being water filling, is easily poured on outside, operates also cumbersome, waste time and energy, how many water fillings is also not easily grasped; Two is that teacher holds fixed head and erases the board, and often needs mobile local, just can clean off a blackboard, use very inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of band extension bar, and easy to use, felt wipes water filling simply, and time saving and energy saving, water injection rate is easily grasped, and felt is wiped and is convenient to cleaning, avoids environmental pollution, is conducive to the moistening blackboard eraser of the healthy rod-type of teachers and students.
For reaching above object, technical solution adopted in the utility model is: the moistening blackboard eraser of this rod-type, be made up of housing, felt wiping, plastic cone body, plastic cone body upper end is inserted in the inner cone of housing, installs felt and wipe in internal diameter, it is characterized in that hollow length bar one end is fixed on above housing, and with the inner space of housing, the other end is communicated with the water cavity of handle, and handle front end is established with taps, seal cover is established in rear end, apertured plug on seal cover.The utility model is also implemented by following measure: described handle, is clear hard plastic production, for ease of grasping water injection rate, establishing on its external wall and using water scale.When using the utility model, first open seal cover, cold water is poured in handle water cavity, then tighten seal cover, when wiping water filling to the felt in housing, housing down, a hand-held handle, stopple under another hand-lifting, makes water cavity enter air, opens with taps, and with reference to using water scale, grasp water consumption, make felt wipe moistening and not drip, after water filling terminates, closedown taps, by stopple plug jail; When erasing the board, arresting handle can erase the board at a distance, uses very convenient; When cleaning felt and wiping, plastic cone body is extracted in housing inner cone, after having cleaned, plastic cone body is inserted in housing inner cone again, install also very simple.
The beneficial effects of the utility model are: compared with current moistening blackboard eraser, have band extension bar, easy to use, and felt wipes water filling simply, and time saving and energy saving, water injection rate is easily grasped, and felt is wiped and is convenient to cleaning, avoids environmental pollution, is conducive to the advantage that teachers and students are healthy.
