Technical Field
[0001] This utility model relates to the field of printing pen technology, specifically to a bubble-type inkjet printing pen. Background Technology
[0002] A thermal inkjet printer is a device that uses thermal inkjet technology for printing. The principle of thermal inkjet technology is to heat the ink to over 300°C instantly by heating a thin-film resistor inside the printhead, forming tiny bubbles. These bubbles rapidly expand and force ink droplets out of the nozzle. The advantages and disadvantages of thermal inkjet technology are its fast printing speed and low cost, which is why it is widely used.
[0003] Because of their small size, printer pens consume ink quickly during prolonged printing, requiring more frequent ink bottle replacements. Traditional printer pens often suffer from poor sealing between the ink bottle opening and the pen's interface, leading to ink leakage. To address this, we propose a bubble-jet printer pen.

[0024] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] Reference Figures 1 to 6This utility model provides a technical solution: a bubble-type inkjet printer pen, including a pen shell 4. In order to facilitate the operator's grip, the pen shell 4 is designed as a long strip structure. The pen shell 4 is provided with a bubble-type inkjet printing component. The bubble-type inkjet printing component includes a rechargeable battery pack 11, a wireless transceiver module and a control board 24 disposed in the pen shell 4.
[0026] The bottom of the pen shell 4 is equipped with a bubble jet printhead 10, and the bottom of the bubble jet printhead 10 protrudes from the bottom of the pen shell 4, so that the bottom of the bubble jet printhead 10 can directly print on the object. The control board 24 is connected to the bubble jet printhead 10, the wireless transceiver module and the rechargeable battery pack 11 respectively. The wireless transceiver module is set on the control board 24 and supports wireless signals such as local area network, Bluetooth, 4G, 5G and 6G.
[0027] The top of the pen casing 4 is equipped with an ink bottle 2, which stores ink. One end of the ink bottle 2 has a nozzle 22, and the inlet end of the nozzle 22 is equipped with a ball-shaped check valve. Figure 4 and Figure 5 As shown, the ball-type one-way valve specifically includes a cylindrical chamber 17 coaxially connected to the liquid inlet end of the bottle mouth 22. A spring 18 is provided inside the cylindrical chamber 17. In order for the spring 18 to extend and retract linearly without bending, the size of the inner cavity of the cylindrical chamber 17 needs to be matched with the spring 18.
[0028] Next, a conical liquid outlet 19 is coaxially provided in the lower end of the cylindrical chamber 17. A sealing ball 15 is provided in the conical liquid outlet 19. The sealing ball 15 is in elastic contact with the spring 18. Under the push of the spring 18, the sealing ball 15 seals the conical liquid outlet 19. A rubber layer is provided on the surface of the sealing ball 15 or the inner surface of the conical liquid outlet 19 to increase airtightness.
[0029] To allow the ink in the ink bottle to flow smoothly into the cylindrical chamber 17, multiple inlets 16 are provided on the side of the cylindrical chamber 17. The ink can flow into the cylindrical chamber 17 from the inlets 16. When the sealing ball 15 moves upward, a gap appears between the sealing ball 15 and the conical outlet 19, allowing the ink to be released from the bottle opening. However, when the sealing ball 15 and the conical outlet 19 are sealed, the ink will not flow out.
[0030] Furthermore, a connector 20 matching the bottle opening 22 is provided on the top of the pen casing 4. A liquid-drawing needle 13 is coaxially mounted inside the connector 20. The middle part of the liquid-drawing needle 13 is connected to the inner wall of the connector 20 via a support body 12. This support body 12 is a rod-shaped or cross-shaped structure. There is a certain gap between the top of the liquid-drawing needle 13 and the top of the connector 20, allowing the liquid-drawing needle 13 to be concealed. The bottom of the liquid-drawing needle 13 is connected to the bubble-type inkjet printing assembly via a pipe. During use, the bottle opening 22 needs to be placed inside the connector 20, such as... Figure 4As shown, an elastic sealing ring 23 is provided on the outer wall of the end of the bottle opening 22 away from the ink bottle 2. Since the sealing ring 23 is located at the lowest end of the bottle opening 22, when the bottle opening 22 is inserted into the connector 20, the sealing ring 23 first makes elastic contact with the connector 20, and at this time the bottle opening 22 and the connector 20 are already sealed. As the bottle opening 22 continues to extend into the connector 20, when the bottle opening 22 is completely placed inside the connector 20, the suction needle 13 opens the ball-shaped one-way valve. The specific process is as follows: Figure 5 As shown, the suction needle 13 is inserted into the conical outlet 19 and pushes the sealing ball 15 upward, so that a gap appears between the sealing ball 15 and the conical outlet 19, allowing the ball-shaped check valve to be opened. The top of the suction needle 13 is angled to prevent the sealing ball 15 from sealing the top of the suction needle 13.
[0031] like Figure 4 As shown, an elastic cylindrical rubber sealing block 26 is also provided in the bottle mouth 22 below the conical liquid outlet 19. A hole is provided in the middle of the cylindrical rubber sealing block 26 to facilitate the insertion of the liquid drawing needle 13. The hole automatically seals when the liquid drawing needle 13 is pulled out. In this way, no ink will flow out when the needle is pulled out and inserted. The ink outflow channel has two sealing mechanisms, which can achieve a better sealing effect.
[0032] To ensure the ink bottle remains stable, the ink bottle 2 is detachably connected to the connector 20 during use. Specifically, an annular seat 14, coaxial with the bottle opening 22, is located at the end of the ink bottle 2 near the bottle opening 22. A cylindrical seat 21, coaxial with the outside of the connector 20, is also located. When the bottle opening 22 is inserted into the connector 20, the cylindrical seat 21 is placed inside the annular seat 14, and the two are threaded together. This is achieved by rotating the ink bottle 2 until the cylindrical seat 21 is placed in the annular seat 14 and tightened. This ensures that the ink bottle 2 remains stably positioned above the pen casing 4 and will not fall off.
[0033] When the ink in an ink bottle 2 is used up and needs to be replaced, simply loosen the ink bottle 2 and pull it out. During the pulling process, the sealing ball 15 separates from the suction needle 13, allowing the sealing ball 15 to seal the bottle opening 22. At this time, the sealing ring 23 keeps the inside of the connector 20 sealed during its upward movement. Therefore, the ink bottle 2 proposed in this application will not leak during installation and removal, and is simple to operate and convenient to use.
[0034] Furthermore, the ink in ink bottle 2 needs to flow into the bubble jet printing assembly to print. The specific process is to connect the bottom of the ink extraction needle 13 to the bubble jet printing assembly through a pipe. Specifically, the ink extraction needle 13 is connected to the bubble jet printing head through a pipe, so that the ink can flow continuously into the bubble jet printing assembly.
[0035] The specific usage process is as follows: the operator holds the pen shell 4 and aligns the bottom of the pen shell 4 with the surface of the object. There is a typing button 25 on the side of the pen shell 4. The typing button 25 is connected to the control board 24. The typing button 25 is located at the lower part of the pen shell 4. This makes it convenient to press the typing button 25 with the thumb when holding the pen shell 4. When the typing button 25 is touched, the control board 24 controls the bubble jet print head 10 to print. The operator can hold the pen shell 4 and move forward at a certain speed. When the hand does not press the typing button 25, the printing stops.
[0036] The pen casing 4 is also equipped with a start / stop button and a charging port 5 connected to the control board 24. Before typing, the printing pen needs to be turned on, and the charging port 5 facilitates charging of the rechargeable battery pack 11.
[0037] Furthermore, this application also establishes a protection mechanism for ink bottle 2, the details of which are as follows: Figure 1 As shown, a first protrusion 3 is provided on the top of the pen shell 4. The first protrusion 3 is stepped on the top of the pen shell 4. The connector 20 is provided on the top of the first protrusion 3. A protective cover 1 is provided on the first protrusion 3. The bottom of the protective cover 1 is placed at the step and the protective cover 1 is detachably connected to the pen shell 4. The protective cover 1 can prevent the ink bottle 2 from touching during use.
[0038] The bottom of the pen casing 4 also features a protection mechanism for the bubble-type inkjet printhead 10, as detailed below. Figure 2 As shown, a second protrusion 9 is provided at the bottom of the pen shell 4. The second protrusion 9 is stepped with the bottom of the pen shell 4, and the bottom of the bubble jet printhead 10 is located inside the second protrusion 9. A protective frame 8 is provided on the second protrusion 9. The protective frame 8 is detachably connected to the pen shell 4. The protective frame 8 can prevent the bubble jet printhead 10 from directly contacting the object when it moves on the surface of the object.
[0039] The specific connection methods between the cover 1 and the pen shell 4, and between the protective frame 8 and the pen shell 4, are snap-fit, snap-fit, or lock-fit. The cover 1 and the pen shell 4, as well as the protective frame 8 and the pen shell 4, can also be connected by magnetic attraction, that is, magnets that attract each other can be set on the stepped surface, the bottom of the cover 1, and the top of the protective frame 8.
[0040] To make it easier to move the protective frame 8 on the object surface, such as... Figure 2 As shown, mounting grooves 6 are provided on both sides of the bottom of the protective frame 8. A roller 7 is rotatably installed in the mounting groove 6. The roller 7 protrudes outside the mounting groove 6, but the distance between the bottom of the roller 7 and the bottom of the bubble inkjet printhead 10 does not exceed the maximum distance of ink jetting of the bubble inkjet printhead 10. That is, this distance hinders ink jetting of the bubble inkjet printhead 10. This distance should not exceed about 3 mm.
[0041] Furthermore, one ink bottle can only hold one color at a time. In order to print color text, such as... Figure 6 As shown, there are four connectors 20, and each of the four connectors 20 contains an ink bottle 2. The bottom of each ink extraction needle 13 is connected to the bubble jet printing assembly through a pipe. The four ink bottles 2 correspond to cyan, magenta, yellow and black, respectively. Of course, the bubble jet printing head 10 can be a color printing head at this time.
[0042] Based on the above embodiments, further optimizations can be made, such as... Figure 1 As shown, a power indicator light connected to the control board is also provided on the top of the pen casing 4, which can indicate whether the battery is fully charged.
[0043] Based on the above embodiments, further optimization is possible: the cover 1 is made transparent, so that the ink level can be directly viewed through the cover 1.
[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
