A new ink-absorbing structure for pen is designed for convenient use. It is located in the space surrounded by the pen point component (a) and the pen back tube (b); comprises an ink tube (1) and a piston (2) installed in the ink tube; when sucking ink, the lower end of the ink tube is communicated to the position below the liquid level of the ink bottle; the method is characterized in that: it has a battery (3) and a motor (4); a motor drive shaft (41); the rotating shaft (41) is fixedly connected with the internal threaded pipe (5); the piston rod of the piston (2) is provided with an external thread to form a screw rod (21); the screw rod (21) is assembled in the internal thread pipe (5) to realize spiral transmission; the battery (3) is connected with the motor (4) through a circuit with a switch (6); the switch key is connected to the outside of the pen rear tube (b). The rotating shaft (41) is fixedly connected with the internal threaded pipe (5), and the middle of the rotating shaft and the internal threaded pipe is realized through a connecting rod (415), namely the rotating shaft, the internal threaded pipe and the internal threaded pipe are fixedly connected with each other.

Description

Ink-sucking structure for fountain pen

Technical Field

The utility model belongs to the technical field of the system pen, especially, relate to blotting structure of pen.

Background

The fountain pen is also called as a fountain pen, has the function of so-called tap water (wherein the tap water is a verb, and the water is a noun and refers to ink), and can continuously write for a long time without frequently going to an ink bottle to dip in the ink. This is because the pen has a small reservoir of ink attached to it, known in the industry as an ink tube. When the ink in the ink tube is used up, the ink bottle is required to be removed to absorb the ink. And the ink absorbing structure is an ink absorbing structure. The early ink absorbing structure is a soft elastic ink bag; when ink is sucked, the back tube of the pen needs to be unscrewed, the ink bag is squeezed by hands, and then the ink bag is loosened, so that the ink bag rebounds to suck ink. The ink absorbing structure in recent years is a piston type structure; when sucking ink, the back tube of the pen needs to be unscrewed, and the piston is pushed and pulled back by hands to realize ink sucking.

Disclosure of Invention

The utility model aims at providing a new ink absorption structure for a pen. When sucking ink, he does not need to open the back tube of the pen and does not need manual operation.

The technical scheme of the utility model is that: a battery and a motor are additionally arranged, and the motor drives the piston to move, so that ink absorption is realized.

Namely: a new ink absorbing structure of a pen is positioned in a space surrounded by a pen point component and a pen rear tube; comprises an ink tube and a piston mounted in the ink tube; when sucking ink, the lower end of the ink tube is communicated to the position below the liquid level of the ink bottle; the method is characterized in that: it has battery and motor; the motor drives a rotating shaft; the rotating shaft is fixedly connected with an internal threaded pipe; the piston rod of the piston is provided with an external thread to form a screw rod; the screw rod is assembled in the internal thread pipe to realize spiral transmission; the battery is connected with the motor through a circuit with a switch; the switch key is connected to the outside of the pen rear tube in an induction mode.

The utility model has the advantages that: the rear tube of the pen is not opened when ink is sucked. Electrically suck ink, and the hand only needs to operate the switch. Bringing convenience to the use.

Drawings

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 is an overall schematic view of a pen incorporating the present invention.

Fig. 2 is a schematic diagram of the present invention. In which switches, batteries and motors are omitted. Please refer to fig. 1.

The notation in the figure is: a pen tip part; b, a rear tube; 1, ink tube; 2 pistons, 21 screws (i.e., piston rods); 3, a battery; 4 motor, 41 rotating shaft (motor shaft or speed reducing shaft of motor), 415 connecting rod; 5, an internal threaded pipe; 6, switching.

Detailed Description

As shown in the figure, a new ink absorbing structure of a pen is positioned in a space surrounded by a pen point part a and a pen back tube b; comprises an ink tube 1 and a piston 2 installed in the ink tube; when sucking ink, the lower end of the ink tube is communicated to the position below the liquid level of the ink bottle; the method is characterized in that: it has a battery 3 and a motor 4; a motor-driven rotating shaft 41; the rotating shaft 41 is fixedly connected with the internal threaded pipe 5; the piston rod of the piston 2 is provided with an external thread to form a screw rod 21; the screw 21 is assembled in the internal thread pipe 5 to realize spiral transmission; the battery 3 is connected with the motor 4 through a circuit with a switch 6; the switch key is connected to the outside of the pen rear tube b.

As shown in the figure, the "rotating shaft 41 is fixedly connected with the internal threaded tube 5", and the middle is realized by the connecting rod 415, that is, the three are fixedly connected with each other. This can accommodate different lengths of pen, facilitating the overall design of the pen.

The switch 6 may be a push-button switch or a two-way toggle switch. The 'switch key is connected to the outside of the pen rear tube b', and the operation key of the switch slightly extends out of the rear end of the pen rear tube, as shown in fig. 1; alternatively, the inductive switch may be surrounded by the rear tube of the pen, but may sense an external operation.

The above embodiments are provided for explaining the present invention to facilitate understanding, and are not intended to limit the scope of patent protection.
