Description

Straight liquid type whiteboard pen

Technical Field

The utility model relates to the technical field of writing tools, in particular to a straight liquid whiteboard pen.

Background

The whiteboard pen is a tool for writing and drawing, and is commonly used in the occasions such as a whiteboard. The structure of the whiteboard pen can be divided into a roll core structure and a direct liquid structure. In the using process of the whiteboard pen with the wrapping core structure, the ink is easy to delaminate, so that the writing color is light, the ink utilization rate is low, and the ink utilization rate is only 60%. The whiteboard pen with the direct-liquid type structure can improve the utilization rate of ink to 90%, the ink is not easy to delaminate, and the writing color is consistent.

The utility model of patent publication No. CN2815714Y discloses a push-push type ink pen, which comprises a button, a pen holder, a push point, an elastic surface, a push rod, a spring, a pen point, an inner plug and a roll core, wherein the button is embedded into the pen holder from the upper end, the elastic surface is arranged in the pen holder and at the upper position, the push point is convexly arranged upwards on the central axis of the elastic surface, the push point is sheathed with the push rod, the push rod is sheathed into the inner plug downwards, namely, on the basis of one straight rod, two cross rods which are mutually perpendicular are respectively arranged at the position close to the upper end and the lower end, the cross rods at the upper end are vertically spaced, so as to keep the push rod not to deviate from the center, the push rod can be smoothly arranged in the push point, the cross rods at the lower end are arranged on the same plane, the bottom of the cross rods are abutted against one end of the spring, the valve is arranged at the lowest end of the push rod, the valve and the straight rod are integrally formed, and liquid in a storage cavity flows into the roll core due to opening the valve, flows out through the fiber head inserted into the roll core, thus the components can be tightly combined, and the components can be assembled conveniently. The ink pen has the advantages that the structure of the wrapping core is reserved, but the ink is stored in the ink cavity of the pen holder, and part of the ink is extruded to the wrapping core in a pressing mode, so that the wrapping core always holds full ink, and the writing color cannot fade. Such prior art ink pens have the following drawbacks: sealing and installing a push point and an elastic surface on the inner wall and the upper position of the pen holder, and inserting a button above the push point; the upper part of the ink cavity is sealed by the elastic surface, the sealing effect is poor, the ink is easy to overflow, and the push button can be pushed by the large pressing force in the using process through the structure assembly, so that the use is inconvenient.
