The push-button block 230 is connected to the second side of the soft rubber push-button sleeve 210.

[0031] In this embodiment, the refillable push-button valve pen 10 is a tail-push-button valve pen. One end of the pen barrel 100 is connected to the pen tip 300. The ink storage chamber 110 of the pen barrel 100 communicates with the accommodation chamber 310 of the pen tip 300 through the valve body 500. That is, the ink in the ink storage chamber 110 can enter the accommodation chamber 310 through the valve body 500 and flow and seep onto the pen core 400. A push-button assembly 200 is provided at the other end of the pen barrel 100. The push-button cylinder 240 of the push-button assembly 200 is threadedly connected to the pen barrel 100 through an external thread 242 and an internal thread 120.

[0032] In this embodiment, when the ink in the ink storage chamber 110 is exhausted, since the push-button cylinder 240 is detachably arranged on the pen barrel 100, the push-button cylinder 240 can be detached from the pen barrel 100, and the soft rubber push-button sleeve 210 is separated from the movable rod 220, so that ink can be replenished into the ink storage chamber 110, that is, ink is replenished into the ink storage chamber 110 through the first end of the ink storage chamber 110, which prolongs the service life of the refillable push-button valve pen 10, reduces the use cost, and at the same time helps to reduce the generation of waste and is more environmentally friendly and sustainable.

[0033] In one embodiment, as Figure 2 shown, a limiting block 231 is convexly arranged on the push-button block 230, and a limiting groove 243 is formed on the side wall of the push-button chamber 241. The limiting block 231 is slidably arranged in the limiting groove 243. Specifically, by the sliding of the limiting block 231 on the push-button block 230 in the limiting groove 243 on the side wall of the push-button chamber 241, a guiding and limiting effect can be achieved, which can not only limit the movement stroke of the push-button block 230 to prevent the push-button block 230 from detaching from the push-button chamber 241, but also enable the push-button block 230 to smoothly press on the soft rubber push-button sleeve 210 and drive the movable rod 220 to move downward.

[0034] Further, the number of the limiting blocks 231 is set to two or more, and the number of the limiting grooves 243 is equal to the number of the limiting blocks 231, which can enable the push-button block 230 to move up and down more smoothly, so as to better drive the movable rod 220 to move.

[0035] In one embodiment, as Figure 2 shown, a sealing ring block 244 is convexly provided on the pressing cylinder 240. The first side of the sealing ring block 244 is connected to the pressing cylinder 240, and the second side of the sealing ring block 244 is movably abutted against the side wall of the pressing cavity 241. Specifically, the sealing ring block 244 is disposed around the outer surface of the pressing cylinder 240. When the pressing cylinder 240 is threadedly connected to the first end of the ink storage cavity 110, the sealing ring block 244 tightly abuts against the side wall of the ink storage cavity 110, and can well seal the first end of the ink storage cavity 110, and can avoid liquid leakage at the connection between the pressing cylinder 240 and the pen barrel 100.

[0036] In one embodiment, as Figure 3 、 Figure 4 and Figure 5 shown, the valve body 500 includes: a valve seat 510, a valve core 520, and an elastic member 530. The valve seat 510 is disposed in the accommodating cavity 310. The second end of the pen core 400 is connected to the valve seat 510. A conduction block 511 is disposed in the valve seat 510. A conduction hole 512 is formed in the conduction block 511. The ink storage cavity 110 communicates with the accommodating cavity 310 through the conduction hole 512. The valve core 520 is movably disposed in the conduction hole 512. The first end of the valve core 520 is connected to the first end of the movable rod 220. The second end of the valve core 520 is movably abutted against the side wall of the conduction hole 512. The first end of the elastic member 530 is connected to the conduction block 511. The second end of the elastic member 530 is connected to the movable rod 220. Specifically, the outer surface of the valve seat 510 is connected to the side wall of the accommodating cavity 310. The conduction block 511 is located in the middle of the valve seat 510. The width of the second end of the valve core 520 is greater than the width of the first end of the valve core 520. The width of the second end of the valve core 520 is adapted to the aperture of the conduction hole 512. The elastic member 530 is a spring. In the initial state, under the action of the spring, the second end of the valve core 520 abuts against the side wall of the conduction hole 512, and can close the conduction hole 512. When the pressing block 230 is pressed to drive the movable rod 220 to move forward, the second end of the valve core 520 is separated from the side wall of the conduction hole 512, that is, the valve body 500 is opened, and the ink in the ink storage cavity 110 can enter the accommodating cavity 310 through the conduction hole 512 and flow into and penetrate the pen core 400, completing the ink filling of the pen core 400 of the refillable pressing valve pen 10. At this time, the spring is in a compressed state. When the force applied to the pressing block 230 is withdrawn, under the action of the spring, the movable rod 220 is reset, and can drive the second end of the valve core 520 to abut against the side wall of the conduction hole 512 again, that is, the valve body 500 is closed, and the ink in the ink storage cavity 110 is re-sealed.

[0037] In one embodiment, as Figure 3 , Figure 4 and Figure 5 shown, the valve body 500 further includes: a valve cover 540, the valve cover 540 is disposed within the valve seat 510, a plurality of conduction grooves 541 are formed on an outer surface of the valve cover 540, the ink storage chamber 110 is sequentially communicated with the receiving chamber 310 through the through hole 512 and each of the conduction grooves 541, a second end of the refill 400 is connected to a first end of the valve cover 540, a limiting chamber is formed on a second end of the valve cover 540, and at least a part of a second end of the valve core 520 is movably disposed within the limiting chamber. Specifically, by providing the valve cover 540, not only can the refill 400 be stably mounted on the valve body 500, but also the moving distance of the valve core 520 can be limited, thereby the conduction degree of the through hole 512 can be limited to maintain a stable ink output. When the pressing block 230 is pressed to drive the movable rod 220 to move forward, the second end of the valve core 520 is separated from the side wall of the through hole 512, and the ink in the ink storage chamber 110 can sequentially enter the receiving chamber 310 through the through hole 512 and the conduction grooves 541 on the valve cover 540, and flow and penetrate onto the refill 400.

[0038] In one embodiment, as Figure 3 and Figure 4 shown, the refillable press-type valve pen 10 further includes: a stirring tube 600, the stirring tube 600 is movably disposed within the ink storage chamber 110, and the stirring tube 600 is sleeved on the movable rod 220. Specifically, by movably providing the stirring tube 600 within the ink storage chamber 110, the ink within the ink storage chamber 110 can be stirred, the fluidity of the ink within the ink storage chamber 110 can be improved, and it can better enter the receiving chamber 310 through the through hole 512 and the conduction grooves 541, and flow and penetrate onto the refill 400. At the same time, the stirring tube 600 is sleeved on the movable rod 220, and can also play a guiding role in the movement of the movable rod 220, such that the movable rod 220 can better move smoothly along a predetermined trajectory within the ink storage chamber 110.

[0039] In one embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the refillable press-type valve pen 10 further includes: a pen cap 700, the pen cap 700 is sleeved on the pen tip 300. Specifically, by sleeving the pen cap 700 on the pen tip 300, a relatively enclosed internal environment can be formed, which can protect the refill 400, and can also reduce air flow, slow down the evaporation rate of the ink, and thereby extend the service life of the refillable press-type valve pen 10.

[0040] In one embodiment, as Figure 2 and Figure 3 shown, a holding block 710 is provided on the pen cap 700. Specifically, by providing the holding block 710 on the pen cap 700, the contact area between the user's hand and the pen cap 700 can be increased, and there is a large frictional force, which facilitates the user to pull out the pen cap 700 from the refillable push-button valve pen 10.
