Detailed ways

The following description is used to disclose the utility model so that those skilled in the art can realize the utility model. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.

A kind of environmental protection marker pen as shown in Figure 1-5, comprises pen body 1 and pen cap 2, and described pen body 1 is provided with nib 13, and described nib 13 protrudes from one end of pen body 1, and described pen cap 2 It is used to cover the end of the pen body 1 provided with the nib 13 when not in use, so as to protect the nib 13 .

The pen body 1 includes a housing 12 with a liquid storage cavity 16 in the middle and a top cover 11 matched with the housing 12 . The pen tip 13 protrudes from one end of the housing 12 to move back and forth, and the upper end of the liquid storage chamber 16 has an opening connected to the outside of the housing, that is, the upper end of the liquid storage chamber 16 communicates with the outside world at the upper end of the housing 12, The top cover 11 is detachably covered on the upper end of the top cover 11 , so that the structure located in the liquid storage chamber 16 can be conveniently installed by disassembling the top cover 11 . The top cover 11 is connected to the casing 12 by means of connections in the prior art such as threads.

A lower liquid chamber 110 is provided on the housing 12 and below the liquid storage chamber 16. At least when in use, the upper end of the pen point 13 is located in the lower liquid chamber 110, which ensures that the upper end of the pen point 13 can be Immersed in the ink so that the ink can flow down the nib 13 . The liquid storage chamber 16 communicates with the lower liquid chamber 110 through the passage 111, and the upper end of the passage 111 communicates with the liquid storage chamber 16 near the upper end of the liquid storage chamber 16, which can ensure that the ink in the liquid storage chamber 16 will not actively into the lower liquid chamber 110.

A piston 15 that can move up and down is arranged in the liquid storage chamber 16 , and the piston 15 is connected with the upper end of the nib 13 through a connecting rod 14 and can move up and down relative to the housing 12 together. A squeeze disc 17 is arranged above the piston 15, and the squeeze disc 17 moves up and down together with the piston 15, and the piston 15 and the squeeze disc 17 can be integrally formed. A detachable sponge 18 and a spring 19 are placed in the liquid storage chamber 16 above the squeeze plate 17, the lower end of the spring 19 leans against the squeeze plate 17, and the upper end leans against the top cover 11, so The spring 19 passes through the sponge 18. The spring 19 is always in a compressed state to ensure that the squeeze plate 17 will not squeeze ink into the lower liquid chamber 112 when not in use. When in use, by exerting a certain force on the shell 12, the nib 13 will drive the squeeze plate 17 to squeeze the sponge 18, so that the ink in the sponge 18 is squeezed out, and enters the lower liquid chamber 110 through the channel 111, and finally Flow out along the nib 13.

At the same time, in order to ensure that the nib 13 will not be pushed out by the spring 19, a limiting plate 112 is provided at the connection between the connecting rod 14 and the nib 13. When the pen is not in use, the limiting plate 112 is against the lower side of the lower liquid chamber 110, Furthermore, when the spring 19 pushes against the pressing plate 17, the spring 19 can be kept in a compressed state all the time, and the nib 13 can not be pushed out from the lower end of the housing 12.

Moreover, since the limiting disk 112 is against the lower side of the liquid storage cavity 16 when not in use, it can prevent ink from flowing out along the nib 13 when the pen is not in use. The diameter of the limiting plate 112 is smaller than that of the lower liquid chamber 110 so that the ink can flow to the bottom of the limiting plate 112 to contact with the nib 13 during use.

Simultaneously, for the convenience of installation, the connecting rod 14, the nib 13, the piston 15, and the squeeze disc 17 can all be set as detachable connections. Moreover, in order to facilitate the installation of the limit plate 112, a detachable structure is arranged at the position near the lower end of the housing 12, similar to that in the prior art, in order to facilitate the pen core to be put into the pen holder, a detachable structure is provided at the lower end of the pen holder. Structure.

A liquid injection hole 113 communicating with the liquid storage chamber 16 is provided on the side wall of the housing 12 , and ink can be injected into the liquid storage chamber 16 through the liquid injection hole 113 . Moreover, at least when the pen is not in use, the liquid injection hole 113 is located above the piston 15, so that it can flow above the piston 15 when injecting ink. Simultaneously for the convenience of injecting ink, described injection hole 113 is preferably positioned between squeeze plate 17 and piston 15, because there is no sponge between squeeze plate 17 and piston 15, ink can enter liquid storage cavity 16 more quickly like this. middle. In order to ensure that the ink between the squeeze plate 17 and the piston 15 can enter the sponge 18, the squeeze plate 17 is provided with a liquid flow hole 171, and the liquid flow hole 171 is located at a distance from the liquid injection hole 113. side, so that when the pen is placed horizontally to inject liquid, the ink can enter the sponge 18 through the liquid hole 171 quickly.

In order to prevent ink from flowing out of the liquid injection hole 113 during normal use, a detachable hole cap 114 is provided on the liquid injection hole 113 to block the liquid injection hole 113 .

The pen cap 2 includes a cap shell 21 with an inner cavity and a cap piston 22 located in the inner cavity of the cap shell 21, and a pen cap liquid injection hole 21 communicating with the inner cavity is provided on the side wall of the cap shell 21, through which the pen cap The liquid injection hole 21 can inject ink into the inner chamber, and when the liquid storage chamber 16 lacks ink, the ink in the pen cap 2 can be injected into the liquid storage chamber 16 . A hole cap 25 is also arranged on the pen cap liquid injection hole 21 . And a push-pull cap 23 connected to the pen cap piston 22 is provided on the side of the pen cap 2 away from the pen body 1, and the push-pull cap 23 facilitates the operation of the pen cap piston 22 and then facilitates injecting the ink in the inner cavity into the liquid storage chamber 16.
