Description

Improved microphone that can be replenished with ink

The present invention relates to an improved refillable ink pen, which is provided with an upper cover for closing the pen holder, and a cross-rotating groove is arranged on the top surface of the upper cover for quickly opening and closing the top opening of the pen, and the ink can be replenished. Target person.

Press, the traditional microphone pen 1, please refer to the first figure, which is mainly composed of a pen holder 11, a pen tip 12 and a pen tip 13. The pen holder 11 is in the shape of an elongated container, and the pen tip 12 is connected to the open end. A tip 13 is provided on the pen tip 12 so that the ink in the pen tip 11 can be injected into the pen tip 13 via the pen tip 12 for writing.

As for the structure of the pen 11 and the pen tip 12, please continue to refer to FIG. 2, the pen tip 11 and the pen tip 12 are generally screwed together, and the pen tip 12 is borrowed because the ink is leaked from the screw joint. The machine is screwed tightly to the barrel 11 and the head of the barrel 11 is fitted with a set of heads 14 located in the sleeve 14 and formed with a sleeve 141 which is just above the upper end of the tip 13. In use, the ink in the barrel 11 is injected into the tip 13 by the sleeve 14 through the sleeve 141 for writing. However, the use of the conventional microphone pen 1 obviously has the following disadvantages:

(1) After the traditional microphone 1 ink is used up, it is generally discarded and then purchased with a new microphone. It cannot be reused. It is obviously wasteful. It is not enough for modern environmental protection.

(2) If the traditional microphone pen 1 needs to replenish the ink, the pen 11 and the pen tip 12 must be unscrewed by the tool, and the ferrule 14 is taken out. After the ink is replenished, the ferrule 14 is sequentially placed, and the pen tip 12 is screwed into the pen shank 11 However, since the pen 11 and the pen tip 12 are strongly disassembled, the tightness effect after the screw is closed is poor, so that water leakage often occurs.

(3) When the pen 12 and the pen 11 are strongly disassembled, since the ink remains in the pen 11, the hand is often full or even covered, so most of the general users are selected. Choose to discard and then purchase a new microphone.

The creator specializes in the development and design of stationery products. He knows that the lack of traditional microphones is not enough to meet the needs. Therefore, it is the determination to initiate reforms, and with years of work experience, it has finally gone through several times. After the experiment, correction and improvement, the original creation was created.

This creation is about an improved refillable ink pen, which is mainly formed with a hollow opening at the top end of the pen holder of the microphone pen, and an internal thread is opened on the inner side of the opening, and an externally threaded upper cover is used to cooperate with the leakage prevention. The washer is screwed into the top of the barrel to close the opening tightly.

As for the top surface of the upper cover, a cross-slot is opened, and a coin or other similar flat-like hard object can be used, and the upper cover can be unscrewed and quickly opened by a cross-rotation groove, so as to replenish the ink from the top opening of the pen, again The upper cover is screwed into the opening, and is also tightly screwed by a coin or other similar flat-shaped hard object, and a leak-proof gasket is arranged in the upper cover to prevent leakage, and the microphone pen can be repeatedly used. Avoid resource wastage.

Figure 7 is a schematic diagram of the present invention after the opening of the cover.

First, as shown in FIG. 3, which is a side view of the present invention, the microphone pen 2 mainly has a pen holder 21, a pen tip 22, and a pen tip 23, and an upper cover 3 is disposed at the top end of the pen holder 21. For detailed structure, please refer to FIG. 4, which is an exploded perspective view of the present invention. The top end of the pen holder 21 is formed with a hollow opening 210, and the inner wall of the opening 210 is provided with an internal thread 211; and the top surface of the upper cover 3 is provided. Open with a spiral groove 31, and to match the opening The inner thread 211 of the inner cover 3 and the outer outer wall 32 of the upper cover 3 are provided with corresponding external threads 32 for inserting a leakage preventing washer 33.

When assembling, please still refer to FIG. 4, firstly insert the leakage preventing washer 33 into the external thread 32 provided on the outer ring wall of the upper cover 3, and then screw the upper cover 3 into the top of the pen holder 21 by the external thread 32. The internal thread 211 of the opening 210, and the opening 210 is tightly closed (as shown in FIG. 5), and the leakage preventing washer 33 that is previously placed can effectively and tightly abut against the inner wall of the pen holder 21, The opening 210 can be surely closed to prevent the ink inside the pen 21 from leaking out.

When the ink in the pen holder 21 is used up, and the ink is to be replenished, then, as shown in Fig. 6, it is a schematic diagram of the opening of the upper cover of the present invention, and the user can use the coin 4 on the body or the like to have a flat shape. The hard object is placed in the cross slot 31 to unscrew the upper cover 3, that is, the upper cover 3 can be taken out from the opening 210 of the pen holder 21 (as shown in FIG. 7), and the ink can be added into the pen holder 21 from the opening 210 at this time. (not shown in the figure), but it should be noted that the pen holder 21 is kept upright, not tilted to prevent the ink from leaking out, and then the upper cover 3 is screwed into the opening 210, and the upper cover 3 is also punched by the cross groove 31 by a hard object such as a coin 4 Closed to prevent ink from leaking out.

Therefore, the design of the upper cover 3, in addition to the convenience of ink replenishment, has the following advantages:

(1) The cross-slot 31 opened on the top surface of the cover 3 of the creation, that is, the coin 4 or other similar flat-like hard objects can be used to quickly and conveniently loosen or tighten the upper cover 3 to avoid temporarily finding out Troubled with tool disassembly.

(2) The external thread 32 provided on the outer ring wall of the upper cover 3 can be fitted into a leak-proof washer 33, and can be screwed into the inner ring wall of the pen holder 21 when screwed into the top end opening 210 of the pen holder 21, thereby utilizing The leakage preventing washer 33 can effectively close to the inner wall of the sheath 21, and can surely prevent ink from leaking out of the opening 210.

(3) The pen 2 of this creation can be used repeatedly to replenish the ink, instead of being lost as if the traditional microphone pen 1 was used up, this creation can save resources and has more environmental protection functions.

In summary, the creation can be quickly and conveniently closed or loosened with the opening of the top end of the pen by the cross slot formed by the top surface of the upper cover, and the ink is replenished, so that the microphone can be heavy. Covering the use, and matching with the leak-proof gasket placed on the upper cover, can effectively prevent the leakage of ink, which has been more advanced and practical than the traditional ones, and has been in compliance with the requirements of the new patent, and has filed a patent application according to law.
