[0035] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0036] The printer spray extraction device 100 and the printer equipment noun part according to the present application are described below with reference to the accompanying drawings.

[0037] like Figures 1 to 3As shown, a specific embodiment of the present application provides a printer foam extraction device 100, comprising an air outlet pipe section 1 and a suction pipe section 2, wherein the pipe wall of the suction pipe section 2 is provided with a suction port 3 extending along the axial direction, and the tube cavity of the suction pipe section 2 is provided with a plurality of air flow channels extending along the axial direction, the air outlet ends of the plurality of air flow channels are all connected with the air outlet pipe section 1, and the air inlet ends of at least two air flow channels are respectively connected with different positions of the suction port 3 along the axial direction.

[0038] When the printer device is in operation, the ink droplets ejected from the nozzle will be atomized and splashed to form droplets. The printer droplet extraction device 100 is used to extend into the main body of the printer device to extract the droplets, so as to prevent the droplets from gathering and contaminating the tiles in the main body. Therefore, in order to absorb as many droplets as possible, a suction port 3 extending in the axial direction is provided on the suction pipe section 2. In the present application, the suction pipe section 2 with multiple air flow channels is used to connect different axial positions of the suction port 3, so that the droplets entering the suction port 3 are diverted and absorbed to the air outlet pipe section 1, thereby ensuring the suction effect of the suction port 3 at the position away from the air outlet in the axial direction, thereby improving the suction effect of the printer droplet extraction device 100.

[0039] It should be noted that in the present application, unless otherwise specified, the “far” used refers to a position that is farther away from the air outlet along the axial direction of the suction pipe segment 2, and the “near” used refers to a position that is farther away from the air outlet along the axial direction of the suction pipe segment 2.

[0040] In some embodiments, the printer spray extraction device 100 further includes a partition plate 4 extending in the axial direction, which is disposed in the lumen of the suction pipe section 2 and divides the lumen of the suction pipe section 2 into two air channels. The air inlet end of one air channel is connected to the proximal end of the suction port 3, and the air inlet end of the other air channel is connected to the distal end of the suction port 3.

[0041] Specifically, the two gas flow channels are the lower flow channel 6 and the upper flow channel 5 located at the upper and lower sides of the partition plate 4, respectively. The suction port 3 is located below the partition plate 4, wherein the upper side of the partition plate 4 refers to the side to which the top surface of the partition plate 4 faces, and the lower side of the partition plate 4 refers to the side to which the bottom surface of the partition plate 4 faces. After the partition plate 4 is installed in the suction pipe section 2, a simulation experiment is conducted on the printer spray extraction device 100 and the experimental results are obtained. The following is the data of the change of static pressure with spatial position.

[0042]

[0043] Table 1 Simulation experiment results

[0044] Among them, X is the lateral position (m) in the cross section of the suction pipe section 2; Y is the vertical position (m) in the cross section of the suction pipe section 2; Z is the axial position (m) of the suction pipe section 2; static pressure is the negative pressure size (Pa).

[0045] According to the simulation experiment results, the values ​​of X and Y remain unchanged in the simulation experiment, and only the Z value and static pressure change, thereby reflecting the static pressure values ​​at different axial positions in the suction pipe segment 2. From the experimental results, the static pressure values ​​in the upper flow channel 5 and the lower flow channel 6 remain basically uniform with the change of the axial position, that is, the suction effect of the upper flow channel 5 and the lower flow channel 6 is uniform, therefore, the negative pressure and wind force in the tube cavity of the suction pipe segment 2 remain uniform and stable as the distance from the suction port increases, that is, the suction effect at the far end of the suction port 3 is effectively guaranteed, thereby improving the suction effect of the printer droplet extraction device 100.

[0046] It should be noted that the detailed operations and steps of the simulation experiments mentioned in the specific embodiments of the present application, the experimental results obtained, and the static pressure value of the experimental results reflecting the negative pressure in the lumen are all well known to those skilled in the art, and do not belong to the core technical points of the present application, and will not be elaborated here.

[0047] Preferably, a vent 7 is formed on the partition plate 4 to connect the upper flow channel 5 and the distal end of the suction port 3. When the partition plate 4 is manufactured, the vent 7 is opened at the distal end of the partition plate 4, so that the air inlet end of the upper flow channel 5 is connected to the suction port 3 to inhale droplets, thereby improving the air suction effect of the printer droplet extraction device 100.

[0048] Those skilled in the art can understand that the present application is not limited to the structural form of opening the vent 7 on the above-mentioned partition plate 4, but can also be a structural form in which the vent 7 connecting the upper flow channel 5 and the suction port 3 is formed between the distal end of the partition plate 4 and the distal end of the suction pipe section 2. The use of the structural form of the vent 7 can reduce the axial length of the partition plate 4. The above two structural forms and other structural forms that can connect the upper flow channel 5 and the suction port 3 should also fall within the protection scope of the present application.

[0049] In some embodiments, a connecting ear plate 13 is provided at the proximal end of the partition plate 4 and fasteners are passed through the connecting ear plate 13 to connect with the tube wall of the suction tube section 2, so as to facilitate the installation and removal of the partition plate 4.

[0050] Those skilled in the art will appreciate that the present application is not limited to the above-mentioned connection structure of the connecting ear plate 13 and the fastener, but may also be a connection structure in which a connector is provided on the partition plate 4 and a slot is formed on the tube wall of the suction pipe segment 2. The partition plate 4 and the inner wall of the suction pipe segment 2 may also be directly made into one piece, that is, they are processed using stamping and other processes well known to those skilled in the art. The above-mentioned connection structure and the one-piece manufacturing method should also fall within the protection scope of the present application.

[0051] In some embodiments, an air guide groove 8 connecting the two air flow channels is formed at one end of the partition plate 4 close to the air outlet pipe section 1. The air outlet ends of the two air flow channels are connected through the air guide groove 8 and then connected to the air outlet pipe section 1, thereby increasing the negative pressure and wind force at the proximal end of the air flow channel, so that the droplets can be smoothly inhaled into the air outlet pipe section 1 and discharged.

[0052] Specifically, the air guide groove 8 is opened at the proximal end of the partition plate 4 and penetrates the partition plate 4 in the up and down directions. A plurality of connecting ear plates 13 connecting the suction pipe section 2 and the partition plate 4 are provided on the upper side of the groove wall of the air guide groove 8. The center line of the air guide groove 8 coincides with the axis of the partition plate 4, and the plurality of connecting ear plates 13 are symmetrically arranged along the axis.

[0053] Furthermore, a plurality of air distribution holes 9 connecting the two air flow channels are provided on the partition plate 4, and the negative pressures of the two air flow channels are balanced through the plurality of air distribution holes 9, thereby achieving a balance of the droplet flow rates of the two air flow channels.

[0054] Preferably, every two air distribution holes 9 are symmetrically arranged on both sides of the axis of the partition plate 4, so as to further accelerate the speed of balancing the negative pressure of the two air paths.

[0055] In some embodiments, the wall of the suction pipe section 2 extends inwardly with a mounting rod 12 that penetrates the partition plate 4, and the partition plate 4 can move along the mounting rod 12 to adjust the size of the two air flow channels. After each adjustment, a simulation experiment is conducted on the printer spray extraction device 100 to obtain experimental results, and then the vertical position of the partition plate 4 is continuously adjusted according to the static pressure value of the experimental results as the spatial position in the air flow channel changes, until the negative pressure and wind force of the air flow channel remain uniform and stable as the distance from the air outlet increases.

[0056] Specifically, there are a plurality of mounting rods 12 which are arranged at intervals along the axial direction, and the mounting rods 12 are arranged perpendicular to the pipe wall of the suction pipe section 2 .

[0057] Preferably, every two mounting rods 12 are symmetrically arranged on both sides of the axis of the partition plate 4, so as to more accurately adjust the vertical position of the partition plate 4.

[0058] It will be understood by those skilled in the art that in the specific embodiment of the present application, the axial length of the partition plate 4, the vertical position of the partition plate 4, the size of the vent 7, the size of the air guide groove 8 and the size of the air distribution hole 9 are all determined based on the experimental results of the simulation experiment, so that the printer droplet extraction device 100 has the best suction effect.

[0059] In some embodiments, a first boss 10 is formed at the axis of the partition plate 4 toward the upper flow channel 5. The first boss 10 extends axially, and the droplets entering the upper flow channel 5 are guided to both sides of the axis of the partition plate 4 through the first boss 10, thereby avoiding the accumulation of droplets at the axis of the partition plate 4 to produce ink aggregation and atomized ink droplets.

[0060] Furthermore, the tube wall of the suction pipe section 2 forms a second boss 11 extending axially inwardly, and a suction port 3 is provided on the top surface of the second boss 11. The droplets entering the lower layer flow channel 6 are guided to both sides of the axis of the suction port 3 through the second boss 11, thereby avoiding the accumulation of droplets and clogging at the suction port 3, thereby improving the suction effect of the printer droplet extraction device 100.

[0061] Specifically, the first boss 10 and the second boss 11 may adopt various cross-sectional forms such as trapezoidal, semicircular, etc., and various cross-sectional forms should also fall within the protection scope of the present application.

[0062] The specific embodiment of the present application also provides a printer device, including a printer spray extraction device 100 and a fan, wherein the fan is in air communication with the printer spray extraction device 100. Since the printer device adopts all embodiments of the printer spray extraction device 100, the printer device has all the beneficial effects brought by the printer spray extraction device 100.
