Abstract

The utility model discloses a dual-purpose pencil for entertainment and writing. The utility model can play musical sounds. The tail section of an ordinary pencil holder is sheathed with one empty pipe. Only a part of the empty pipe is sheathed with the pencil holder. The pencil holder can be twitched in the empty pipe. The end opening of the empty pipe which is not sheathed with pencil holder part is a playing opening which is namely called an air-stream inlet. The empty pipe wall is provided with a sound outlet. The air-stream outlet which communicates with the air-stream inlet and the sound outlet in the empty pipe is smaller than the air-stream inlet, and the air-stream outlet and the sound outlet are arranged on the same radial sides of the empty pipe. The pencil holder is twitched, an air column vibration is generated in the empty pipe, and the musical sounds are given out. The utility model has the advantages of simple structure, and low cost. The functions of the pencil are increased. The utility model can serve as a toy entertainment and a writing implement.

Description

Dual-purpose pencil for entertainment and writing

Double-purpose pen is write in a kind of amusement that blows out music.

At present, though the function of pen day by day increases, have concurrently in the prior art to play wind instruments and do not find with writing function pen.

The purpose of this utility model is to provide a kind of pen that music and melody also can be write that blows out.

The technical solution of the utility model is: this has common penholder, the penholder afterbody is with a blank pipe, only some is enclosed within on the penholder blank pipe, both contacted partial shape kissings, penholder can be twitched along axis direction in blank pipe, blank pipe is not enclosed within the part of penholder, its port is airflow inlet (promptly playing wind instruments mouth), having sound mouth near the airflow inlet place on the tube wall of blank pipe, for forming the vibration sounding of air-flow, the air stream outlet that is communicated with airflow inlet and sound mouth in the blank pipe is less than airflow inlet, and air stream outlet and sound mouth are positioned at radially homonymy of blank pipe.Hold penholder and be exposed at the outer part of blank pipe, penholder is twitched in blank pipe as plunger, play out music and melody because of producing the gas column vibration.

The utility model has increased the function of pen, and simple in structure, cost is low, both can be used as writing implement again as the toy amusement.

Accompanying drawing of the present utility model is an example structure schematic diagram.

As shown, penholder (1) afterbody is with a blank pipe (2), only some is enclosed within on the penholder (1) blank pipe (2), locating to have sound mouth (4) near airflow inlet (3) on the tube wall of blank pipe (2), the area that is communicated with airflow inlet (3) and the air stream outlet (5) of sound mouth (4) in the blank pipe is preferably less than the area of 1/2nd airflow inlets (3); The penholder head is with the cap for brush (6), plays wind instruments a mouthful place and is with a hygienic cap (7), thereby make this more resemble a common pen on profile; Can adopt mounting means such as screw thread, draw-in groove between the cap for brush (6) and the penholder (1), when playing wind instruments as toy, the cap for brush and penholder can be synchronized with the movement, and hand are made dirty and the nib damage to avoid nib; For playing wind instruments conveniently, make the unlikely sound mouth (4) of in twitch, blocking of penholder (1), go up close nib place at penholder (1) and be provided with spacing ring (8), spacing ring (8) is integral with penholder (1), spacing ring (8) external diameter is greater than the internal diameter of blank pipe (2), spacing ring (8) to the distance of penholder (1) tail end goes up less than blank pipe (2) and penholder (1) joins port is to the distance of sound mouth (4), this pen also can be directly with the cap for brush (6) as limiting component.
