Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, a pen with an ink-out early warning function comprises a pen holder 1, wherein a communication cavity 7 is formed in the middle position above the pen holder 1, a miniature pressure sensor 6 is installed at the inner wall of the communication cavity 7, the miniature pressure sensor 6 is of an LC928 type and is used for detecting the ink pressure of the position where the miniature pressure sensor 6 is located when ink is arranged in the communication cavity 7, a control chip 5 is inlaid at the outer wall of the pen holder 1, the control chip 5 is used for receiving a pressure signal output by the miniature pressure sensor 6 and analyzing and judging the pressure signal, the miniature pressure sensor 6 is electrically connected with the control chip 5, a lead is adopted between the miniature pressure sensor 6 and the control chip 5, and after the lead is installed, the channel where the lead is located is plugged by using sealant to prevent the ink from flowing out; more specifically, in order to provide power and a manual control switch, a small button cell can be provided, the manual control switch is a wave switch, the switch can be turned on during writing, and after the pressure value monitored by the micro pressure sensor 6 is lower than a certain value, the control chip 5 can control the lamp strip 3 to illuminate. The button cell and the manual control switch can be arranged on the pen holder 1.

The pen is characterized in that an annular groove is formed in the circumferential direction of the pen holder 1, a lamp strip 3 is arranged in the annular groove, the lamp strip 3 is electrically connected with a control chip 5, the purpose of arranging the lamp strip 3 is that after a signal output by a miniature pressure sensor 6 exceeds a certain value, the control chip 5 controls the lamp strip 3 to illuminate, so that a user can timely perceive the lamp strip when writing, and the early warning function is achieved.

Specifically, an ink bag 8 is connected to the upper position of the pen holder 1, an ink storage cavity 9 for containing ink is formed in the center of the ink bag 8, the ink storage cavity 9 is communicated with the communication cavity 7, a capillary tube 2 communicated with the communication cavity 7 is arranged inside the pen holder 1, and a pen point 11 is arranged at the lower position inside the pen holder 1; ink can be sucked into the ink reservoir 9 and allowed to enter the communication chamber 7 from the ink reservoir 9 and finally flow out of the nib 11 through the capillary 2. The structures and principles of the pen tip 11 and the capillary tube 2 belong to the conventional technology in the prior art, and are not described herein in detail.

Specifically, the outer surface of the control chip 5 is flush with the circumferential surface of the pen holder 1, because the user holds the pen holder 1 when holding the pen, and thus the problem of hand interference caused by the control chip 5 can be avoided.

Specifically, install transparent cover 4 in the ring channel, transparent cover 4 sets up the circumference outside position at lamp area 3, just transparent cover 4's outer wall is parallel and level mutually with the circumference of pen-holder 1, and wherein, transparent cover 4 is the plastics material for protect lamp area 3, and make things convenient for the light that lamp area 3 sent outwards to show.
