[0003] Electrofluidic printing technology uses electrohydrodynamics to pull liquid out of the nozzle to form a Taylor cone using an electric field. Since the nozzle has a high electric potential, the liquid at the nozzle will be subjected to electro-shear stress; when the local charge force exceeds the surface tension of the liquid, the charged liquid is ejected from the nozzle and then breaks into liquid columns or small droplets. By changing the flow rate, voltage, liquid properties and nozzle structure, electrofluidic printing modes with different jet shapes and breakup mechanisms can be formed, namely electrospinning, electrospray and electrospray.

[0004] In the related art, a voltage is applied to the inside of the electrofluidic nozzle by arranging an electrode wire inside the electrofluidic nozzle, leading the electrode wire out from the side of the electrofluidic nozzle, and connecting it to an external power supply device.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0041] The embodiment of the present application provides an electric fluid nozzle module and inkjet printing system with a stable power supply form, which locates the installation position of the electric fluid nozzle by abutting the positioning block with the positioning structure, and uses a magnetic power supply component to adsorb and fix the positioning block to fix the electric fluid nozzle, and at the same time, the electrode assembly is powered by the positioning block and the nozzle body, so the positioning installation and power supply operation of the electric fluid nozzle are performed synchronously, which is convenient and fast, and improves the installation and removal efficiency of the electric fluid nozzle. The present application solves the technical problem that the installation and power supply of the electric fluid nozzle in the related art are cumbersome and cannot meet the needs of efficient disassembly and assembly of the electric fluid nozzle.

[0042] Reference Figure 1-Figure 4 , an electric fluid nozzle module with a stable power supply form, comprising a mounting base 1, an electric fluid nozzle 2 and a magnetic power supply component 3. After the electric fluid nozzle 2 is mounted on the mounting base 1, the magnetic power supply component 3 magnetically fixes the electric fluid nozzle 2 and simultaneously supplies power to the electric fluid nozzle 2. The fixing and power supply operations of the electric fluid nozzle 2 are performed synchronously, thereby improving the installation and removal efficiency of the electric fluid nozzle 2.

[0043] Reference Figure 1-Figure 3 A mounting groove 1a is provided on one side of the mounting seat 1, and both ends of the mounting groove 1a are open. The electrofluid nozzle 2 is installed in the mounting groove 1a. In this embodiment, the nozzle of the electrofluid nozzle 2 extends out of the mounting groove 1a, and the nozzle of the electrofluid nozzle 2 extends to the bottom of the mounting seat 1.

[0044] With this arrangement, during subsequent printing processing, since the nozzle of the electrofluidic nozzle 2 extends to the bottom of the mounting base 1, the nozzle of the electrofluidic nozzle 2 can be lowered as close to the printing plane as possible without being affected by the mounting base 1, thereby increasing the range of adjustment of the printing height and ensuring the printing quality.

[0045] Furthermore, a positioning structure 11 is provided in the installation groove 1 a , and the positioning structure 11 is used as a reference for the installation position of the electrofluidic nozzle 2 to improve the consistency of each installation of the electrofluidic nozzle 2 .

[0046] Reference Figure 2-Figure 4 , wherein the electrofluid nozzle 2 includes a nozzle body 21, an electrode assembly 22 and a positioning block 23, wherein the electrode assembly 22 is installed inside the nozzle body 21, and the electrode assembly 22 is electrically connected to the nozzle body 21. The positioning block 23 is sleeved on the nozzle body 21, and the positioning block 23 is electrically connected to the nozzle body 21. The nozzle body is located in the mounting groove 1a, and the positioning block 23 is also located in the mounting groove 1a. The positioning block 23 abuts against the positioning structure 11 in the mounting groove 1a to position the electrofluid nozzle 2 relative to the mounting seat 1.

[0047] Specifically, the positioning structure 11 includes a positioning surface, the groove wall of the installation groove 1a is stepped to have a protruding portion to form the positioning surface, or a convex block is fixed in the installation groove 1a to form the positioning surface. The bottom surface of the positioning block 23 abuts against the positioning surface to achieve the positioning of the installation position of the electrofluid nozzle 2.

[0048] In this embodiment, the mounting base 1 is made of an insulating material, wherein the mounting base 1 can be a plastic part.

[0049] The insulating arrangement of the mounting seat 1 can not only reduce the weight of the entire module, but also avoid the electrical connection between the magnetic power supply component 3 and the mounting seat 1, eliminating potential safety hazards. In addition, the mounting seat 1 does not generate an electric field force. During printing, the mounting seat 1 does not generate an electric field force to cause electric field crosstalk to the printing, thereby ensuring the printing quality.

[0050] Reference Figure 2-Figure 4 In this embodiment, the positioning structure 11 includes a positioning sleeve, which is made of metal. An opening is provided on the circumferential side of the positioning sleeve so that the nozzle body 21 can enter the positioning sleeve from the side of the positioning sleeve. After the nozzle body 21 enters the positioning sleeve, the circumferential outer side of the nozzle body 21 fits the positioning sleeve.

[0051] Reference Figure 2-Figure 4 Furthermore, the positioning sleeve is embedded in the installation groove 1a, and the groove wall of the installation groove 1a is provided with a step surface, and the bottom surface of the positioning sleeve is pressed against the step surface, and the step surface also positions the installation position of the positioning sleeve. After the nozzle body 21 enters the positioning sleeve, the positioning block 23 is located above the positioning sleeve. By changing the position of the positioning block 23 and the nozzle body 21, the bottom surface of the positioning block 23 is fitted with the top surface of the positioning sleeve, and the positioning installation of the electric fluid nozzle 2 is realized, and it is ensured that each time the electric fluid nozzle 2 is installed in the installation groove 1a, the relative position of the electric fluid nozzle 2 and the mounting seat 1 is consistent, thereby improving the consistency of the installation of the electric fluid nozzle 2.

[0052] In this way, after the nozzle body 21 is installed on the positioning sleeve, the positioning block 23 is tightly attached to the positioning sleeve, and the nozzle body 21 is tightly attached to the positioning sleeve, so as to ensure that the voltage is stably transmitted from the positioning block 23 to the nozzle body 21. In addition, the positioning sleeve is made of metal and has a weak deformation ability. After the positioning block 23 is tightly attached to the positioning sleeve, it is not easy to cause the positioning sleeve to deform, thereby ensuring the installation accuracy of the electrofluid nozzle 2.

[0053] Furthermore, the corners of the positioning sleeve have an arc transition. Since the positioning sleeve is also added with voltage, after the arc transition at the corners of the positioning sleeve, it is not easy to have tip discharge, and the voltage at the fluid nozzle 2 is more stable, ensuring the printing accuracy. In addition, the corners with arc transition also make it convenient to install the positioning sleeve into the installation groove 1a.

[0054] Reference Figure 4 , Figure 6 and Figure 7 The nozzle body 21 includes a main body 211 and a needle body 212. The main body 211 is made of a conductive material, the electrode assembly 22 is electrically connected to the main body 211, and the positioning block 23 is sleeved on the main body 211 and electrically connected to the main body 211. The needle body 212 is made of an insulating material, the needle body 212 is plugged into the main body 211, and the electrode assembly 22 extends to the injection point of the needle body 212.

[0055] Reference Figure 4 , Figure 6 and Figure 7 , the main body 211 is connected with the needle body 212. Specifically, the main body 211 and the needle body 212 are plugged together to form a detachable connection between the main body 211 and the needle body 212, so as to facilitate the replacement of the needle body 212. The needle body 212 is located below the mounting seat 1, so as to avoid interference from the mounting seat 1 and be as close to the printing plane as possible. Since the needle body 212 is insulated, the functional liquid after power-on will not cause electrochemical corrosion to the needle body 212, but maintain the shape of the needle body 212, thereby ensuring the consistency of multiple printings, ensuring the controllable landing position of the printing, and ensuring the printing accuracy.

[0056] In this embodiment, the main body portion 211 and the needle body portion 212 are threadedly matched to be fixed.

[0057] Reference Figure 4 , Figure 6 and Figure 7 , the electrode assembly 22 is inserted through the needle body 212 and the main body 211, and one end of the electrode assembly 22 extends to the nozzle of the needle body 212, and the electrode assembly 22 is electrically connected to the main body 211. Specifically, the electrode assembly 22 is located in the middle of the needle body 212 and the main body 211, that is, the center lines of the electrode assembly 22, the needle body 212 and the main body 211 are consistent. Since the relative positions of the electrode assembly 22, the needle body 212 and the main body 211 are consistent, the flight path consistency of the printed droplets is better, thereby improving the printing consistency. In addition, the electrode assembly 22 extends to the nozzle of the needle body 212 to apply a voltage at the nozzle, and the electric field force is applied to the functional liquid closer to the ejection position of the functional liquid, so that the ejected droplets are less affected by the electric field force crosstalk, thereby improving the printing accuracy.

[0058] Reference Figure 4 , Figure 6 and Figure 7Specifically, the electrode assembly 22 includes an electrode holder 221 and an electrode wire 222, and the electrode wire 222 is coaxially fixed on the electrode holder 221. The electrode holder 221 is inserted at the top of the needle body 212, and the electrode wire 222 is inserted into the needle body 212, and the electrode wire 222 extends to the injection port of the needle body 212. After the needle body 212 is inserted and matched with the main body 211, the electrode holder 221 is partially located in the main body 211 and is electrically connected to the main body 211.

[0059] Reference Figure 4 , Figure 6 and Figure 7 Furthermore, the electrofluid nozzle 2 also includes an elastic member 24. A matching hole is provided at the end of the main body 211 through which the needle body 212 is inserted. The elastic member 24 is installed in the matching hole. The two ends of the elastic member 24 respectively press against the electrode seat 221 and the bottom of the matching hole. As the main body 211 and the needle body 212 are plugged in and out, the elastic member 24 presses the electrode seat 221. The elastic member 24 is made of a conductive material. In this embodiment, the elastic member 24 includes a spring.

[0060] With such an arrangement, the elastic member 24 not only presses against the electrode seat 221 to fix the position of the electrode seat 221 , but also electrically connects the electrode seat 221 and the main body 211 , thereby making the electrical connection between the electrode assembly 22 and the main body 211 more stable, ensuring that the electrode assembly 22 is subsequently supplied with stable power through the main body 211 .

[0061] Reference Figure 3-Figure 5 , wherein the magnetic power supply component 3 is installed at the bottom of the installation groove 1a. The magnetic power supply component 3 includes a magnetic component 32 and a power supply component 31. The magnetic component 32 is magnetically attracted to the positioning block 23, so that the power supply component 31 and the positioning block 23 are tightly pressed, and the power supply component 31 and the positioning block 23 are stably electrically connected. The power supply component 31 is electrically connected to an external power supply device.

[0062] With this arrangement, while the magnetic attraction member 32 magnetically attracts and fixes the positioning block 23, the power supply member 31 is also pressed against the positioning block 23 along with the magnetic attraction member 32 to be electrically connected to the positioning block 23. The magnetic attraction member 32 is used to ensure that the power supply member 31 is pressed against the positioning block 23, thereby ensuring the stability of the electrical connection between the positioning block 23 and the power supply member 31. Then, the electrical connection between the power supply member 31 and the electrode assembly 22 is achieved through the nozzle body 21 and the positioning block 23. Therefore, while positioning and fixing the electric fluid nozzle 2, the electrode assembly 22 is also electrically connected to the power supply member 31, which facilitates the power supply to the inside of the electric fluid nozzle 2. Therefore, the positioning and installation of the electric fluid nozzle 2 and the power supply operation of the electric fluid nozzle module are performed simultaneously, which is convenient and quick, thereby improving the installation and removal efficiency of the electric fluid nozzle 2.

[0063] Reference Figure 3-Figure 5Specifically, a receiving groove 1b is provided at the bottom of the installation groove 1a, and the magnetic power supply component 3 is placed in the receiving groove 1b. The power supply component 31 is flush with the bottom of the installation groove 1a, or the power supply component 31 protrudes from the bottom of the installation groove 1a.

[0064] In this way, the arrangement of the receiving groove 1 b leaves installation space for the magnetic power supply component 3 .

[0065] Reference Figure 2-Figure 5 Furthermore, a wiring hole 1c is opened on the side of the installation groove 1a, and the wiring hole 1c is connected to the accommodating groove 1b. The wiring hole 1c is suitable for allowing the conductive wire to pass through, so as to facilitate the use of the conductive wire to electrically connect the magnetic power supply component 3 and the external power supply device.

[0066] In this way, the arrangement of the wiring hole 1 c facilitates the routing of the conductive wire, rationally utilizes the structural layout, and improves the integrity of the structure on the mounting base 1 .

[0067] Reference Figure 3-Figure 5 The magnetic power supply assembly 3 further comprises a mounting sleeve 33, which is embedded in the receiving groove 1b. The power supply member 31 comprises a power supply ring, which is sleeved on the magnetic member 32 and penetrates the mounting sleeve 33.

[0068] In this way, the magnetic power supply assembly 3 is a separately arranged mounting sleeve 33, a power supply ring and a magnetic attraction member 32, which are conveniently installed together in the receiving groove 1b after being assembled. The mounting sleeve 33 is arranged to protect the power supply ring and the magnetic attraction member 32, and improve the integrity of the three structures. The mounting sleeve 33, the power supply ring and the magnetic attraction member 32 can be assembled after being processed separately to meet the needs of mass production.

[0069] In this embodiment, the magnetic attraction member 32 includes a permanent magnet or an electromagnet.

[0070] Reference Figure 1 and Figure 2 The electric fluid nozzle module with stable power supply also includes a limit assembly 4, which is used to press the electric fluid nozzle 2 tightly into the mounting groove 1a to prevent the electric fluid nozzle 2 from moving randomly or even leaving the mounting seat 1.

[0071] Reference Figure 1 and Figure 2 The limiting assembly 4 includes a limiting plate 41 and a limiting screw 42. One end of the limiting plate 41 is hinged to a side surface where the mounting groove 1a is provided, and the other end of the limiting plate 41 is fixed to the mounting seat 1 by a bolt, so that the limiting plate 41 spans the mounting groove 1a. The limiting screw 42 is threadedly penetrated through the limiting plate 41, and when the limiting plate 41 spans the mounting groove 1a, the limiting screw 42 extends to the mounting groove 1a and presses against the electrofluid nozzle 2.

[0072] In this way, after the electrofluid nozzle 2 is installed in the installation groove 1a, the limiting plate 41 is rotated so that the limiting plate 41 crosses the installation groove 1a, and the free end of the limiting plate 41 is fixed to the mounting seat 1, and then the limiting screw 42 is tightened so that the limiting screw 42 is pressed against the electrofluid nozzle 2. In this embodiment, the limiting screw 42 is pressed against the main body 211. To achieve the fixation of the electrofluid nozzle 2. When the electrofluid nozzle 2 needs to be disassembled, the limiting screw 42 is loosened, and the fixed state of the free end of the limiting plate 41 is released, and the limiting plate 41 is rotated to make the limiting plate 41 away from the installation groove 1a, so that the electrofluid nozzle 2 can be easily taken out.

[0073] It should be noted that the limiting assembly 4 can be used to help limit the electrofluid nozzle 2 from being separated from the mounting base 1. Due to the different experiences of the installation workers, when the limiting screw 42 is turned to tighten the electrofluid nozzle 2, it is easy for the positioning block 23 to not be pressed tightly against the power supply 31. Therefore, the arrangement of the magnetic attraction member 32 ensures that the power supply 31 is stably electrically connected to the positioning block 23.

[0074] The embodiment of the present application provides an electric fluid nozzle module with a stable power supply form. When the electric fluid nozzle 2 is installed on the mounting seat 1, the electric fluid nozzle 2 is placed in the mounting groove 1a, and the positioning block 23 is in contact with the positioning structure 11 to position the installation position of the electric fluid nozzle 2, so that the consistency of each installation of the electric fluid nozzle 2 is better. In addition, after the electric fluid nozzle 2 is placed in the mounting groove 1a, the magnetic power supply component 3 magnetically absorbs the positioning block 23 through the magnetic suction member 32 to fix the installation position of the electric fluid nozzle 2, so as to achieve rapid installation and removal of the electric fluid nozzle 2.

[0075] In addition, while the magnetic attraction member 32 magnetically attracts and fixes the positioning block 23, the power supply member 31 is also pressed against the positioning block 23 with the magnetic attraction member 32 to be electrically connected to the positioning block 23, and then the positioning block 23 and the electrode assembly 22 are electrically connected through the nozzle body 21 to realize the electrical connection between the power supply member 31 and the electrode assembly 22. Therefore, while positioning and fixing the electric fluid nozzle 2, the electrode assembly 22 is also electrically connected to the power supply member 31, which facilitates the power supply to the inside of the electric fluid nozzle 2. Therefore, the positioning and installation of the electric fluid nozzle 2 in the electric fluid nozzle module and the power supply operation are performed simultaneously, which is convenient and fast, and improves the installation and removal efficiency of the electric fluid nozzle 2.

[0077] Another embodiment of the present application provides an inkjet printing system. Since the inkjet printing system includes the above-mentioned electric fluid nozzle module with a stable power supply form, the beneficial effects of the inkjet printing system are consistent with the beneficial effects of the above-mentioned electric fluid nozzle module with a stable power supply form, which will not be repeated here.
