Abstract

The utility model relates to a variable temperature pen, which comprises a pen point, a pen holder and pen cap, wherein, the pen holder is of tubular structure, and an interlayer facing downwards is arranged at the end face of the tubular wall; the interlayer is ring-shaped with the direction parallel to the axial line; the tail end of the pen holder is provided with a water injection pipe communicated with the interlayer; in addition, the pen cap is covered at the opening of the pen holder and the interlayer. When temperature needs to be changed, user can inject liquid of different temperature into the interlayer of the pen holder to change surface temperature of the pen holder through heat transfer between the liquid and the pen holder, thereby changing hand temperature of user. The utility model has the advantages of reasonable structure, aesthetic appearance, extensive application, simple process and low cost.

Description

The alternating temperature pen

Technical field the utility model relates to a kind of study article, especially a kind of alternating temperature pen.

Background technology is well-known, and pen is a most important writing implement in the study and work.But a present function is fairly simple, and writing function only is provided, and can't satisfy people's needs.Particularly in two seasons of summer in winter, environment temperature is not suitable for writing with pen, and phenomenons such as hand perspiration, frostbite often take place, and influences the study and work effect.For this reason, we provide a kind of new-type alternating temperature pen that changes surface temperature by liquid heat transfer.

The summary of the invention the purpose of this utility model provides a kind of alternating temperature pen, is used to solve the problem that conventional pen can't change surface temperature by heat transmission.

For achieving the above object, the utility model alternating temperature pen comprises nib, penholder and the cap for brush, and penholder is a tubular structure, offers interlayer downwards at the tube wall end face, and interlayer also is a ring-type, and direction is parallel with axis; Be provided with water injection pipe at the penholder end, and water injection pipe communicates with interlayer; The cap for brush covers at penholder and interlayer opening part.

After adopting said structure, the user can change the temperature of penholder according to environment temperature and personal like, and when changing, the user can inject the liquid water of different temperatures in the penholder interlayer, heat transmission by liquid water and penholder changes the penholder surface temperature, thereby influences user's hand temperature.

The utility model has the advantages that: rational in infrastructure, good looking appearance, be widely used, technology is simple, cheap, can independently change surface temperature, satisfy the different demands of people.

Description of drawings Fig. 1 is the overall structure schematic diagram of the utility model alternating temperature pen.

The specific embodiment as shown in Figure 1, the utility model alternating temperature pen comprises nib 1, penholder 2 and the cap for brush, penholder 2 is a tubular structure, offers interlayer 3 downwards at the tube wall end face, interlayer 3 also is a ring-type, direction is parallel with axis; Be provided with water injection pipe 4 at penholder 2 ends, and water injection pipe 4 communicates with interlayer 3; The cap for brush covers at penholder 2 and interlayer 3 opening parts.
