Abstract
The utility model discloses a leak protection china ink whiteboard pen, including the cap for brush (1), take a body (2) in ink storehouse, its characterized in that: a end of fixed rubber sleeve (3) of body, outer one pen tail end cover (4) of suit of rubber sleeve. In order to make cap for brush internal gas pressure and external atmospheric pressure phase etc. The top of the cap for brush is equipped with a little through -hole. In order to make pen tail end cover internal gas pressure and external atmospheric pressure phase etc. Be equipped with a little through -hole on the pen tail end cover. Because the inflation through the rubber sleeve and the function of shrink, when ink storehouse internal gas pressure changes, rubber sleeve inflation or contract, messenger's ink storehouse internal gas pressure is unchangeable, has prevented the ink leakage effectively, has reached completely the utility model discloses can prevent the invention mesh of ink leakage.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly relates to a kind of ink leakage proof white board marker.
Background technology
As everyone knows, enter each classroom in multimedia, most school also improves blackboard; most use blank, also instead of chalk with white board marker, from then on no longer includes dust and produces; protect the health of teacher, for teacher creates more superior working environment.But in the use procedure of reality, white board marker often has the shortcoming of ink leak, the ink spilt gently then pollutes textbook or the hand of teacher, heavy then may leak splash teacher clothes or trousers on, make the teacher attended class very awkward, certainly such clothes and trousers just again cannot have been worn, and cause economic loss.Therefore, design a kind of white board marker of ink ink leak that can prevent and become those skilled in the art's problem demanding prompt solution.
Utility model content
The purpose of this utility model is to provide a kind of ink leakage proof white board marker that can prevent ink leakage to overcome the deficiencies in the prior art.Its concrete technical scheme is: ink leakage proof white board marker comprises a body of the cap for brush, band ink storehouse, and the tail end of a body fixes a rubber sleeve, and rubber sleeve is set with a pen end lid outward.
In order to make cap for brush internal gas pressure equal with ambient pressure, the top of the cap for brush is provided with a small through hole.
In order to make pen end lid internal gas pressure equal with ambient pressure, pen end covers and is provided with a small through hole.
When using the utility model ink leakage proof white board marker, the air first in emptying, then adds ink and just can normally use in a body.
As can be seen from the technical solution of the utility model, owing to passing through the expansion of rubber sleeve and the function of contraction, when ink storehouse internal gas pressure changes, rubber sleeve expands or shrinks, make ink storehouse internal gas pressure constant, effectively prevent ink leakage, fully meet the goal of the invention that the utility model can prevent ink leakage.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model ink leakage proof white board marker.
