[0035] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] By providing an ink stirrer and an ink tank in the embodiments of the present application, the problem that ink often splashes out when the stirrer stirs the ink in the ink tank in the prior art is solved, and waste of ink is effectively prevented.

[0037] The technical solutions in the embodiments of the present application for solving the above technical problems are generally as follows:

[0038] As Figures 1 - 8As shown in the figure, by providing a first tank opening structure and a second tank opening structure on the tank body and combining with an ink agitator, the installation of the agitator is realized by using the slots on the first tank opening structure. When the agitator is working, the agitator and the tank body form a closed space, which is convenient for the agitator to stir the ink in the tank body, and solves the problem that ink often splashes out when the agitator stirs the ink in the ink tank in the prior art.

[0039] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0040] As Figures 1 - 3 shown, an ink tank includes a tank body 20, and a first tank opening structure 21 and a second tank opening structure 22 are provided in the opening direction of the tank body 20;

[0041] The first tank opening structure 21 communicates with the tank body 20, and the inner diameter of the first tank opening structure 21 is smaller than the inner diameter of the tank body 20;

[0042] A slot 211 is provided on the outer side wall of the first tank opening structure 21 for inserting the agitator used in the ink tank;

[0043] During stirring, the agitator is in a closed state with the ink tank through the slot 211;

[0044] The inner diameter of the second tank opening structure 22 is the same as the inner diameter of the first tank opening structure 21, and the outer diameter of the second tank opening structure 22 is smaller than the distance between the proximal end of the slot 211 close to the center point and the center point;

[0045] External threads are provided on the outer surface of the second tank opening structure 22 for installing the tank cover on the ink tank.

[0046] By providing a first tank opening structure 21 and a second tank opening structure 22 on the tank body 20, the installation of the agitator is realized by using the slot 211 on the first tank opening structure 21. When the agitator is working, the agitator and the tank body 20 form a closed space, which is convenient for the agitator to stir the ink in the tank body 20, and solves the problem that ink often splashes out when the agitator stirs the ink in the ink tank in the prior art.

[0047] As Figures 1 - 6 shown, an ink agitator is installed on the ink tank for stirring the ink in the ink tank. The ink agitator includes a cover body 10, a stirring structure is provided on the cover body 10, and a plurality of insertion blocks 101 corresponding to the slots 211 one by one are installed on the outer side wall of the cover body 10. The cover body 10 is closed with the ink tank through the plurality of insertion blocks 101 and the plurality of slots 211.

[0048] By providing insertion blocks 101 on the cover body 10 that correspond one-to-one with the slots 211 on the ink tank, the installation of the stirrer and the ink tank is achieved. The overall structure is convenient to install and improves the stability of the stirrer for stirring the ink.

[0049] A rotating structure is rotatably connected to the cover body 10, and the stirring structure is installed on the rotating structure to control the rotation of the stirring structure.

[0050] A motor 11 is detachably connected to the center of the cover body 10. The motor 11 is fixed to the cover body 10 through a fixing member. The rotating structure is fixedly sleeved on the output end of the motor 11. By providing the motor 11, the rotation of the rotating structure is controlled, and then the rotation of the stirring structure provided on the rotating structure is controlled, thereby realizing the stirring operation of the stirring structure on the ink in the ink tank.

[0051] The stirring structure includes a plurality of stirring rods 121. The stirring rods 121 are in an S shape. Specifically, the stirring rods 121 can be composed of a plurality of irregular S-shaped rod bodies, such as Figures 4 - 5 shown.

[0052] By setting the stirring rods 121 in an S shape, it is convenient for the stirring rods 121 during stirring. The stirring rods 121 at different depths in the ink tank are closer to different position points of the center of the ink tank, improving the stirring effect of the stirring rods 121 on the ink.

[0053] A plurality of the stirring rods 121 are all threadedly connected to the rotating structure. By controlling the rotational connection between the stirring rods 121 and the rotating structure, the distance between the lower ends of the stirring rods 121 and the inner bottom of the tank body 20 is adjusted, and the same stirring point on the stirring rods 121 is located at different depths of the ink tank, realizing different stirring points on the stirring rods 121 at the same depth and further improving the stirring effect of the ink at the same level.

[0054] The rotating structure includes a rotating disk 12. A plurality of the stirring rods 121 are annularly distributed on the rotating disk 12. The rotating disk 12 is in the shape of a spool, that is, a cylindrical spool shape. The rotating disk 12 is composed of an upper disk, a lower disk, and a connecting member. The upper disk is located on the side of the cover body 10 away from the ink tank, the lower disk is located on the side of the cover body 10 close to the ink tank, and the connecting member passes through the cover body 10 and is rotatably connected to the cover body 10. A plurality of the stirring rods 121 are all rotatably connected to the rotating disk 12. The threaded portions of a plurality of the stirring rods 121 pass through the upper disk, the lower disk, and the connecting member and extend to the outside of the upper disk. Specifically, as Figure 6 shown.

[0055] By controlling the threaded portions of the stirring rods 121 to pass through the upper disk, the lower disk, and the connecting member and extend to the outside of the upper disk, it is possible to control the rotation of the corresponding stirring rods 121 from the outer surface of the cover body 10 when the cover body 10 and the tank body 20 are closed, improving the convenience of adjusting the stirring rods 121.

[0056] Specifically, a fixing sleeve 122 is provided on the threaded portion of the stirring rod 121 passing through the rotating disk 12. The setting of the fixing sleeve 122 facilitates the rotation of the stirring rod 121. In actual application, a labor-saving rod can be installed on the threaded portion passing through the rotating disk 12 to facilitate the manual rotation of the stirring rod 121.

[0057] Embodiment 1:

[0058] A plurality of the connecting members are provided. A plurality of arc-shaped grooves corresponding to the connecting members one by one are formed in the cover body 10. The arcs of the arc-shaped grooves are all centered on the corresponding point of the axis of the output end of the motor 11. The connecting members pass through the corresponding arc-shaped grooves and rotate on the cover body 10.

[0059] During operation, the motor 11 controls the output shaft to rotate forward once and then controls the output shaft to rotate backward once. The output shaft rotates alternately in the forward direction to realize the stirring operation of the stirring rod 121 on the ink. The rotation angles are all the radian of the arc-shaped groove.

[0060] Specifically, two connecting members are provided. Two arc-shaped grooves are formed in the cover body 10. The connecting members are located in the corresponding arc-shaped grooves. The radian of the arc-shaped groove is 170°. The arc length of the connecting member is 1 / 17 of the arc length of the arc-shaped groove. Thus, when the rotating disk 12 rotates forward and backward alternately, the single rotation radian can be as large as possible each time.

[0061] By setting the cover body 10 and the rotating structure in the above form, while the stirring rod 121 extends to the outer surface of the cover body 10, the rotation of the rotating structure and the cover body 10 is realized. The rotating disk 12 is controlled to rotate forward by a certain angle and backward by a certain angle to realize the stirring operation of the stirring rod 121 on the ink.

[0062] Embodiment 2:

[0063] As Figure 8 shown, a circular groove is formed in the cover body 10. The circular groove penetrates through the cover body 10. A plurality of U-shaped plates 123 are provided on the cover body 10. The plurality of U-shaped plates 123 are arranged in a staggered manner with the plurality of stirring rods 121. When realizing the integrity of the rotating disk 12, it prevents the U-shaped plates 123 from blocking the stirring rods 121 and facilitates the rotation of the stirring rods 121.

[0064] During operation, after controlling the rotating disk 12 to rotate forward for several circles, the rotating disk 12 is controlled to rotate backward for several circles. The specific number of rotation circles can be controlled according to actual needs.

[0065] In a specific application process, based on Embodiment 1 or Embodiment 2, the motor 11 can be replaced with a rotating shaft member, and the rotating structure fixedly installed at the output end of the motor 11 is installed on the rotating shaft member. The rotating shaft member is rotatably connected to the cover body 10. By buffering the rotating shaft member with the motor 11, manual stirring operation can be realized. Since the viscosity of the ink is low, it is not laborious to manually control the rotating shaft member to drive the rotating disk 12 to rotate, and it is more suitable for the requirement of stirring the ink in the ink tank.

[0066] During use, in the initial state, the positional relationship between the stirring rod 121 and the cover body 10 is as Figure 6 shown. At this time, multiple stirring rods 121 can all enter the cavity of the tank body 20 through the first tank opening structure 21 and the second tank opening structure 22, and come into contact with the ink standing still in the cavity. The insertion block 101 on the cover body 10 is inserted into the tank body 20. By rotating the stirring rod 121 outside the cover body 10, the rotation of the stirring rod 121 is controlled. The stirring rod 121 gradually changes from the Figure 6 state to the Figure 7 state. Figure 7 In the

[0067] state, the stirring rod 121 can better stir the ink on the outer ring of the tank body 20;

[0068] By controlling the overall rotation of the rotating disk 12, multiple stirring rods 121 distributed on the rotating disk 12 are controlled to stir the ink in the tank body 20 synchronously;

[0068] After the stirring is completed, the multiple stirring rods 121 are restored to the Figure 6 state, which is convenient for the stirrer to be taken out of the tank body 20, completing the stirring operation of the ink. The stirred ink is put into use. When not in use, the tank cover is installed on the second tank opening structure 22 to seal and store the ink in the tank body 20. When using it again, repeat the above stirring operation.

[0069] In summary, compared with the prior art, the following beneficial effects are achieved:

[0070] 1. By providing the first tank opening structure 21 and the second tank opening structure 22 on the tank body 20, the installation of the stirrer is realized by using the slot 211 on the first tank opening structure 21. When the stirrer works, the stirrer and the tank body 20 form a closed space, which is convenient for the stirrer to stir the ink in the tank body 20, solving the problem that ink often splashes out when the stirrer stirs the ink in the ink tank in the prior art.

[0071] 2. By setting the stirring rod 121 in an S shape, it is convenient for the stirring rod 121 to be at different positions near the center point of the ink tank at different depths of the ink tank during stirring, improving the stirring effect of the stirring rod 121 on the ink.

[0072] 3. By controlling the rotational connection between the stirring rod 121 and the rotating structure, the distance between the lower end of the stirring rod 121 and the inner bottom of the tank body 20 is adjusted, so as to control the same stirring point on the stirring rod 121 to be at different depths of the ink tank, achieving different stirring points on the stirring rod 121 at the same depth, and further improving the stirring effect of the ink at the same level.
