Description

Technical Field

[0001] The invention relates to the field of multifunctional tool pens, and more particularly to a controllable direct liquid type tool pen. Background Art

[0002] A tool pen refers to a pen product that combines traditional writing functions with special tool functions. It usually incorporates a variety of practical tools in its design, such as marker pens, gel pens, eyeliner pens, foundation pens, and nail polish pens, etc. The direct liquid type refers to a pen that directly provides ink through its own ink storage chamber. By installing a water core in the pen, the ink is adsorbed on the water core and is continuously transported to the pen tip through the contact between the water core and the pen tip.

[0003] The pen tip of the direct liquid writing pen in the prior art all adopts a ball head, that is, a ball is installed at the tip of the pen tip. When writing, the ball rotates to bring out ink to achieve the writing function. Although this direct liquid writing pen is not prone to ink leakage, ink interruption or ink fading during writing, and ensures the continuity and clarity of writing, its function is relatively single. After the ink is filled in the pen body, it can only be used for writing and cannot be used in different work fields. It is a disposable pen, and its ink and other material components are likely to cause serious pollution damage to the environment, with high recycling costs and difficulty in recycling and reuse.

[0004] Therefore, new solutions need to be proposed to solve this problem. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a controllable direct liquid tool pen. When used in different fields, different liquid materials can be poured into the pen body. When in use, the liquid output can be controlled in real time according to actual conditions to ensure the use effect, thereby greatly improving the adaptability of the tool pen.

[0006] The above technical purpose of the present invention is achieved through the following technical scheme: a controllable direct liquid tool pen includes a pen body, a fixing ring is clamped on the pen body, a through groove is opened on both sides of the fixing ring, elastic blocks are fixedly connected to the two through grooves, a through groove is opened on the pen body for the elastic block to be placed, and an automatic liquid discharge extrusion mechanism is provided on the pen body.

[0007] According to this solution, when used in conjunction with the extrusion mechanism, the elastic block can be pressed to squeeze the liquid inside the pen body. When a larger amount of liquid is required, it can be pressed hard, which greatly increases the applicability of the tool pen.

[0008] The present invention is further configured as follows: the extrusion mechanism includes a fixed block fixedly connected to the inner wall of the pen body, a threaded rod slidably connected to the fixed block, a rotating column threadedly connected to the threaded rod, a limiting ring fixedly connected to the rotating column, and a limiting cover slidably connected to the rotating column, the limiting cover is threadedly connected to the pen body, the threaded rod is provided with a sealing component for pushing liquid, and the pen body is provided with a blocking component for preventing leakage.

[0009] According to this solution, the rotating column can be rotated to make the threaded rod drive the sealing component to move inside the pen body to push the injected liquid, and cooperate with the sealing component to eliminate the bubbles in the injected liquid as much as possible. The limit ring cooperates with the limit cover and the limit cover is tightened on the pen body to limit the position of the rotating column, preventing the rotating column from idling and unable to drive the threaded rod, thereby ensuring the use effect of the tool pen.

[0010] The present invention is further configured as follows: the sealing assembly includes a pushing block fixedly connected to one end of the threaded rod away from the limiting cover, a sealing ring is fixedly connected to the threaded rod, the outer wall of the pushing block and the outer wall of the sealing ring are both in contact with the inner wall of the pen body, and the pushing block and the sealing ring have elastic deformation capabilities.

[0011] According to this solution, a pushing block and a sealing ring are provided, which can greatly improve the sealing effect and prevent the liquid from entering between the pushing block and the limiting cover when the injected liquid is pushed, thereby making the liquid output more stable.

[0012] The present invention is further configured as follows: the blocking component includes a liquid outlet head threadedly connected to the pen body, a limit column detachably connected inside the liquid outlet head, and a blocking cover clamped on the limit column, the blocking cover is provided with a through hole, the limit column is fixedly connected to a support frame at one end away from the pen body, the support frame is fixedly connected to a spring, and the other end of the spring is fixedly connected to a blocking ball for blocking the through hole.

[0013] According to this solution, the sealing ball can be used to seal the through hole through the spring pressure to prevent the injected liquid from flowing out when it is not in use. When the elastic block is pressed, the injected liquid will push the sealing ball, causing the spring to contract to discharge the liquid. When the pressing of the elastic block ends, the elastic block resets, and the spring also resets to drive the sealing ball to seal the through hole. At this time, due to the pressure, the sealing component will automatically push the injected liquid to achieve automatic pushing, which greatly improves the practicality of the tool pen.

[0014] The present invention is further configured as follows: a positioning ring is fixedly connected to the middle end of the spring.

[0015] According to this solution, the spring can be prevented from being dislocated, which causes the sealing ball to be unable to seal the through hole.

[0016] The present invention is further configured as follows: a positioning block is detachably connected to a side of the rotating column away from the liquid outlet head, and a magnet is fixedly connected to the top side of the positioning block.

[0017] According to this solution, the positioning block can be installed on the rotating column to make it easier to rotate the rotating column, and the tool pen can be placed on the workbench by a magnet, making the tool pen easier to take, easier to fill with liquid and avoid loss.

[0018] The present invention is further configured as follows: the pen body is threadedly connected with liquid outlet head 2, liquid outlet head 3, liquid outlet head 4 and liquid outlet head 5, the inner walls of liquid outlet head 1, liquid outlet head 2, liquid outlet head 3, liquid outlet head 4 and liquid outlet head 5 are fixedly connected with a plurality of protrusions, and the limiting column is provided with grooves for the protrusions to be placed.

[0019] According to this solution, after the tool pen is used in a field, the limit column in the liquid outlet head 1 can be taken out, and then the sealing cover clamped on the limit column can be removed, and then the sealing ball and the spring can be cleaned, and then the liquid outlet head 1 can be replaced with liquid outlet head 2, liquid outlet head 3, liquid outlet head 4 or liquid outlet head 5 according to the field of use, so as to improve the utilization rate of the tool pen.

[0020] The present invention is further configured such that: the first liquid outlet head, the second liquid outlet head, the third liquid outlet head and the fourth liquid outlet head are all detachably connected with pen caps.

[0021] According to the solution, the pen cap can prevent external dust from contaminating the first, second, third and fourth liquid outlet heads, thereby ensuring the use effect of the tool pen when it is used next time.

[0022] In summary, the present invention has the following beneficial effects: when applied in different fields, different liquid materials can be poured into the pen body, and the liquid outlet head one can be replaced with liquid outlet head two, liquid outlet head three, liquid outlet head four or liquid outlet head five according to different usage scenarios. The liquid outlet amount can also be controlled in real time according to actual conditions during use to ensure the use effect, thereby greatly improving the adaptability of the tool pen. For example, liquid outlet head one to liquid outlet head five can be used in the beauty industry, medical industry, industrial industry, art industry and model industry according to different purposes.

DETAILED DESCRIPTION

[0025] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] A controllable direct liquid tool pen, such as Figure 1-Figure 5 As shown, it includes a pen body 1, a fixing ring 2 is clamped on the pen body 1, through grooves 3 are provided on both sides of the fixing ring 2, and elastic blocks 4 are fixedly connected to the two through grooves 3, and a through groove 2 5 is provided on the pen body 1 for the elastic block 4 to be placed, and the pen body 1 is provided with an automatic liquid discharge extrusion mechanism, which includes a fixing block 6 fixedly connected to the inner wall of the pen body 1, a threaded rod 7 slidably connected to the fixing block 6, a rotating column 8 threadedly connected to the threaded rod 7, a limiting ring 9 fixedly connected to the rotating column 8, and a limiting cover 10 slidably connected to the rotating column 8, the limiting cover 10 is threadedly connected to the pen body 1, a sealing component for pushing liquid is provided on the threaded rod 7, and a blocking component for preventing liquid leakage is provided on the pen body 1. The component includes a pushing block 11 fixedly connected to one end of the threaded rod 7 away from the limit cover 10, a sealing ring 12 is fixedly connected to the threaded rod 7, the outer wall of the pushing block 1 and the outer wall of the sealing ring 12 are both in contact with the inner wall of the pen body 1, the pushing block 11 and the sealing ring 12 have elastic deformation ability, the blocking component includes a liquid outlet head 13 threadedly connected to the pen body 1, a limit column 14 detachably connected in the liquid outlet head 13 and a blocking cover 15 clamped on the limit column 14, a through hole 16 is opened on the blocking cover 15, the limit column 14 is fixedly connected to one end away from the pen body 1 with a support frame 17, the support frame 17 is fixedly connected with a spring 18, and the other end of the spring 18 is fixedly connected with a blocking ball 19 for blocking the through hole 16.

[0027] like Figure 1-Figure 5As shown, before use, the rotating column 8 is first moved. Since the rotating column 8 is blocked by the limit cover 10 at this time, the threaded rod 7 of the rotating column 8 will drive the pushing block 11 to move, so that the pushing block 11 and the sealing ring 12 gradually move away from the liquid outlet head 13 until they cannot rotate. Then, the liquid outlet head 13 is rotated again, and the liquid outlet head 13 is removed. Then, the liquid to be used is poured into the pen body 1, and then the liquid outlet head 13 is installed on the pen body 1 and tightened. Then, the rotating column 8 is rotated in the opposite direction to make the pushing block 11 and the sealing ring 12 gradually move away from the liquid outlet head 13. The squeezing block 11 and the sealing ring 12 gradually approach the liquid outlet head 13. At this time, the liquid in the pen body 1 will be squeezed by the pushing block 11 and the sealing ring 12. When being squeezed, the bubbles in the liquid will be squeezed out, and as the rotating column 8 continues to rotate, the liquid will push the blocking ball 19 and lift the blocking ball 19 so that the blocking ball 19 is no longer in contact with the blocking cover 15. At this time, the spring 18 is in a compressed state, and the liquid will also enter the liquid outlet head 13. The pen can be used after the liquid is precipitated from the liquid outlet head 13.

[0028] like Figure 1-Figure 5 As shown, when in use, the elastic block 4 is pressed according to the amount of liquid discharge required, and the liquid in the pen body 1 will push the blocking ball 19 and lift the blocking ball 19 so that the blocking ball 19 is no longer in contact with the blocking cover 15. At this time, the spring 18 is in a compressed state and then precipitates out from the liquid discharge head 13. After the liquid is precipitated out from the liquid discharge head 13, the elastic block 4 is released, and the spring 18 is reset to drive the blocking ball 19 to seal the through hole 16. At this time, due to pressure reasons, the pushing block 11 and the sealing ring 12 will move one end distance to the side of the liquid discharge head 13 and automatically push the liquid, so that when the elastic block 4 is pressed next time, it can still be ensured that the liquid is precipitated normally from the liquid discharge head 13. When no liquid is precipitated by pressing the elastic block 4, the pushing block 11 and the sealing ring 12 can be rotated by rotating the rotating column 8 to squeeze the liquid and burst the bubbles in the liquid, thereby ensuring that the pushing block 11 and the sealing ring 12 can automatically push the liquid normally.

[0029] like Figure 4 As shown, a positioning ring 20 is fixedly connected to the middle end of the spring 18 to prevent the spring 18 from being dislocated, which would cause the blocking ball 19 to be unable to block the through hole 16 .

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a positioning block 23 is detachably connected to the side of the rotating column 8 away from the liquid outlet head 13, and a magnet 24 is fixedly connected to the top side of the positioning block 23. The positioning block 23 can be installed on the rotating column 8 to make it easier to rotate the rotating column 8, and the tool pen can be placed on the workbench through the magnet 24, making the tool pen easier to take, easier to fill with liquid and avoid loss.

[0031] like Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown, the pen body 1 is threadedly connected with a second liquid outlet head 25, a third liquid outlet head 26, a fourth liquid outlet head 27 and a fifth liquid outlet head 28; a plurality of protrusions 21 are fixedly connected to the inner walls of the liquid outlet head 13, the second liquid outlet head 25, the third liquid outlet head 26, the fourth liquid outlet head 27 and the fifth liquid outlet head 28; a groove 22 for the protrusions 21 to be placed is provided on the limiting column 14; the liquid outlet head 13, the second liquid outlet head 25, the third liquid outlet head 26 and the fourth liquid outlet head 27 are all detachably connected with a pen cover 29; the pen cover 29 can prevent external dust from contaminating the liquid outlet head 13, the second liquid outlet head 25, the third liquid outlet head 26 and the fourth liquid outlet head 27, so as to ensure the use effect of the tool pen when it is used next time; the liquid outlet head 13 can be used as a gluing pen when installed; the liquid outlet head 25 can be used as a marker pen when installed; the liquid outlet head 3 26 can be used as a marker pen when installed It can be used as a nail polish gel pen; if the liquid outlet head 4 27 is installed, it can be used as a hazel-shaped paintbrush; if the liquid outlet head 5 28 is installed, it can be used as an eyeliner pen, so as to improve the utilization rate of the tool pen. When the tool pen is used in a field, the limit column 14 in the liquid outlet head 13 can be taken out, and then the blocking cover 15 clamped on the limit column 14 can be removed, and then the blocking ball 19 and the spring 18 can be cleaned, and then the limit column 14 can be inserted into the liquid outlet head 25, the liquid outlet head 3 26, the liquid outlet head 4 27 or the liquid outlet head 5 28 according to the field of use, so as to improve the utilization rate of the tool pen. For example, the liquid outlet head 13, the liquid outlet head 25, the liquid outlet head 3 26, the liquid outlet head 4 27 and the liquid outlet head 5 28 can be used in the beauty industry, the medical industry, the industrial industry, the art industry and the model industry according to different purposes.

[0032] Working principle: Before use, first move the rotating column 8. Since the rotating column 8 is blocked by the limit cover 10 at this time, the threaded rod 7 of the rotating column 8 will drive the pushing block 11 to move, so that the pushing block 11 and the sealing ring 12 gradually move away from the liquid outlet head 13 until they cannot rotate. Then, the liquid outlet head 13 is rotated again, and the liquid outlet head 13 is removed. Then, the liquid to be used is poured into the pen body 1, and then the liquid outlet head 13 is installed on the pen body 1 and tightened. Then, the rotating column 8 is rotated in the opposite direction to make the liquid outlet head 13 move. The pushing block 11 and the sealing ring 12 gradually approach the liquid outlet head 13. At this time, the liquid in the pen body 1 will be squeezed by the pushing block 11 and the sealing ring 12. When being squeezed, the bubbles in the liquid will be squeezed out, and as the rotating column 8 continues to rotate, the liquid will push the blocking ball 19 and lift the blocking ball 19 so that the blocking ball 19 is no longer in contact with the blocking cover 15. At this time, the spring 18 is in a compressed state, and the liquid will also enter the liquid outlet head 13. The liquid can be used after it is precipitated from the liquid outlet head 13.

[0033] When in use, the elastic block 4 is pressed according to the required amount of liquid discharge, and the liquid in the pen body 1 will push the blocking ball 19 and lift the blocking ball 19 so that the blocking ball 19 is no longer in contact with the blocking cover 15. At this time, the spring 18 is in a compressed state and then precipitates out from the liquid outlet head 13. After the liquid is precipitated out from the liquid outlet head 13, the elastic block 4 is released, and the spring 18 is reset to drive the blocking ball 19 to block the through hole 16. At this time, due to pressure reasons, the pushing block 11 and the sealing ring 12 will move an end distance to the side of the liquid outlet head 13 and automatically push the liquid, so that when the elastic block 4 is pressed next time, it can still be ensured that the liquid is precipitated normally from the liquid outlet head 13.

[0034] In this way, different liquid materials can be poured into the pen body 1 when applied in different fields, and the liquid outlet head 1 13, liquid outlet head 25, liquid outlet head 3 26, liquid outlet head 4 27 or liquid outlet head 5 28 can be replaced according to different usage scenarios. The liquid outlet amount can also be controlled in real time according to actual conditions during use to ensure the use effect, which greatly improves the adaptability of the tool pen. For example, the liquid outlet head 1 13, liquid outlet head 25, liquid outlet head 3 26, liquid outlet head 4 27 and liquid outlet head 5 28 can be used in the beauty industry, medical industry, industrial industry, art industry and model industry according to different purposes.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
