Description

Technical Field

[0001] The utility model relates to the technical field of emulsified ink pens, in particular to a special pen head for emulsified ink. Background Art

[0002] Emulsion ink is a common type of printing ink, usually used for printing packaging, labels, books and other printed materials. The addition of emulsifier enables the ink to mix with water to form an emulsion, so it is called emulsion ink. Emulsion ink is also used in ballpoint pens.

[0003] The utility model with patent number CN209063751U discloses a spring nib, an emulsified ink refill and an emulsified ink pen. The spring nib comprises a nib body, a first sphere, a second sphere and a spring. The nib body is provided with a first accommodating hole, a second accommodating hole and a third accommodating hole which are mutually interpenetrating from the front end to the rear end, wherein the diameters of the second accommodating hole, the first accommodating hole and the third accommodating hole increase in sequence; the first sphere is rotatably arranged in the first accommodating hole; the second sphere is rotatably arranged in the third accommodating hole and abuts against the first sphere, and the diameter of the second sphere is greater than that of the first sphere; the spring is compressed in the third accommodating hole; wherein the second accommodating hole is circumferentially arranged with a plurality of ink grooves, the ink grooves are formed by the inner wall of the second accommodating hole being recessed inwardly, the ink grooves extend along the extension direction of the nib body, the front end surface of the ink grooves contacts the first sphere, and the rear end of the ink grooves is connected with the third accommodating hole, the spring nib can better adapt to emulsified ink and prevent leakage.

[0004] The disadvantage of the existing emulsified ink pen tip is that the first ball can be closely attached to the bowl mouth of the front end of the first receiving hole by the pressure of the spring, which can prevent ink from dripping. The single blocking structure will cause ink leakage after the bowl mouth of the ball seat body is deformed. Therefore, we propose a special emulsified ink pen tip. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a special pen tip for emulsified ink, which solves the problems raised by the background technology.

[0013] Furthermore, a connecting tube is provided at the bottom end of the ink conduit, and a protruding engaging portion is sleeved on the outer side of the connecting tube.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] When not in use, the spring pushes the small ball and the large ball upward through the Y-shaped support frame, the large ball moves upward and is close to the bowl mouth of the ball seat body to form a first seal, and the small ball moves upward and is close to the first blocking part to form a second seal, so that even if the bowl mouth of the ball seat body is damaged, ink leakage will not occur;

[0016] The limit ring and the cross inside it support the spring, and the spring pushes the small ball and the large ball through the Y-shaped support frame. The top of the Y-shaped support frame is against the bottom of the small ball and will not tilt. A guide groove is opened on the outside of the Y-shaped support frame to play a guiding role, so that the limit ring and the cross will not affect the emulsified ink flowing into the ink conduit. The limit ring is clamped in the holder, which is easy to install and disassemble;

[0017] The emulsified ink pen tip is formed by a large ball moving up and closely attached to the bowl mouth of the ball seat body to form a first seal, and a small ball moving up and closely attached to the first blocking part to form a second seal. Even if the bowl mouth of the ball seat body is damaged, ink leakage will not occur. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 In the embodiment of the utility model, it includes an ink conduit 1, a ball seat body 2, a large ball 5, a small ball 6, a first blocking portion 7 and a cross 111;

[0026] A ball seat body 2 is arranged on the top of the ink conduit 1, a small ball 6 is embedded in the ball seat body 2, a first blocking portion 7 is arranged inside the bottom of the small ball 6 in the ball seat body 2, a large ball 5 is embedded inside the ball seat body 2 located at the top of the small ball 6, a second blocking portion 9 is arranged inside the ball seat body 2 located at the bottom of the large ball 5, a receiving groove 8 is opened inside the ball seat body 2 between the second blocking portion 9 and the first blocking portion 7, a limiting ring 11 is arranged inside the ink conduit 1, a spring 12 is arranged on the top of the limiting ring 11, and a Y-shaped support frame 13 is welded to the top of the spring 12.

[0027] A holder 10 is provided inside the ink conduit 1 , and a limiting ring 11 is engaged inside the holder 10 , so that the installation and removal of the limiting ring 11 are convenient.

[0028] The limiting ring 11 is provided with a cross 111 , and a reserved groove 112 is provided between the cross 111 and the limiting ring 11 . The reserved groove 112 prevents the limiting ring 11 and the cross 111 from affecting the flow of the emulsified ink into the ink conduit 1 .

[0029] Among them, the bottom end of the spring 12 is located on the cross 111, the Y-shaped support frame 13 is located at the bottom of the small ball 6, and the cross 111 supports the spring 12 in the limiting ring 11.

[0030] Among them, the outer side of the Y-shaped support frame 13 is equidistantly provided with guide grooves 131 , which play a guiding role and facilitate the ink to flow onto the small ball 6 .

[0031] The bottom end of the ink conduit 1 is provided with a connecting tube 3, and a protruding engaging portion 4 is sleeved on the outer side of the connecting tube 3. The setting of the connecting tube 3 facilitates its insertion into the refill, and the protruding engaging portion 4 prevents the connecting tube 3 inserted into the refill from falling off.

[0032] The working principle of the utility model is as follows: when writing, the large ball 5 is forced to squeeze the small ball 6, so that the large ball 5 and the small ball 6 move downward, and the large ball 5 is blocked by the second blocking portion 9. When writing, the large ball 5 rotates to drive the small ball 6 to rotate, and the emulsified ink flowing into the ball seat body 2 flows into the receiving groove 8 and adheres to the outside of the small ball 6, so that the emulsified ink adheres to the surface of the large ball 5 when it rotates. When not in use, the spring 12 pushes the small ball 6 and the large ball 5 to move upward through the Y-shaped support frame 13, and the large ball 5 moves upward to be close to the bowl mouth of the ball seat body 2 to form a first seal, and the small ball 6 moves upward to be close to the first blocking portion 7 to form a second seal. Second, the seal ensures that ink will not leak even if the bowl mouth of the ball seat body 2 is damaged. The limit ring 11 and the cross 111 inside it support the spring 12. The spring 12 pushes the small ball 6 and the large ball 5 through the Y-shaped support frame 13. The top of the Y-shaped support frame 13 is against the bottom of the small ball 6 and will not tilt. A guide groove 131 is provided on the outside of the Y-shaped support frame 13 to guide the flow. The reserved groove 112 between the limit ring 11 and the cross 111 ensures that the limit ring 11 and the cross 111 will not affect the flow of emulsified ink into the ink conduit 1. The limit ring 11 is engaged in the holder 10 for easy installation and disassembly.
