CN203126211U - Inflating pen - Google Patents

Abstract

The utility model relates to stationery, in particular to an inflating pen, and aims to mainly solve the problem that pen oil in existing pens is prone to being frozen to disable writing. The inflating pen comprises a pen body, and is characterized in that a closed cavity is arranged inside the pen body and an inflating one-way air valve is arranged at the tail of the pen body. The inflating pen is simple in structure and novel in appearance; and when the pen oil in the pen body is frozen due to cold, the inflating pen can be inflated by a user through an inflating port at the tail of the pen body to increase air pressure inside the pen body, and the oil in the pen body is compressed to outflow from a pen point easily, so that writing is fluent.

Description

A kind of Air-filling pen

Technical field

The utility model relates to a kind of stationery, especially relates to a kind of Air-filling pen.

Background technology

In the winter of cold, the thickness that can become of the oil in the ball pen becomes very difficult thereby make to write.

Summary of the invention

The purpose of this utility model provides a kind of Air-filling pen, and its oil that mainly solves in the existing pen is frozen in easily, and causes the problem that can't write.

Above-mentioned technical problem of the present utility model is solved by following technical scheme.

A kind of Air-filling pen of the present utility model comprises one-pen, it is characterized in that described pen inside is provided with an airtight cavity, and is provided with the Non-return air valve of an inflation at an afterbody.

The utlity model has simple in structure, outward appearance novelty, the pen oil in pen, because when cold is frozen, the people can inflate in pen by the inflation inlet of an afterbody, and the inner air pressure of pen is increased, oil in the compressing pen makes that oil is easier to flow out from nib, thus make write more smooth.

Description of drawings

Accompanying drawing 1 is structural representation of the present utility model.

The specific embodiment

Below by embodiment, and by reference to the accompanying drawings the technical solution of the utility model is described in further detail.

Embodiment, as shown in Figure 1, a kind of Air-filling pen of this example comprises one-pen 1, it is characterized in that described pen 1 inside is provided with an airtight cavity 2, and is provided with the Non-return air valve 3 of an inflation at pen 1 afterbody.

During use, the pen oil in pen because cold is when freezing, the people can inflate in pen by the inflation inlet of an afterbody, and the inner air pressure of pen is increased, the oil in the compressing pen makes that oil is easier to flow out from nib, thereby make write more smooth.

Claims (1)

1. an Air-filling pen comprises one-pen, it is characterized in that described pen inside is provided with an airtight cavity, and is provided with the Non-return air valve of an inflation at an afterbody.
