DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] See also Figure 1 - Figure 3 The present invention provides a technical solution: an ink storage device for an inkjet device, comprising an ink storage cavity 800, which is mainly a container for storing ink. A screw-fixed cover plate 700 is provided on the top of the ink storage cavity 800, and an ink filling port device 100 is provided on the upper surface of the screw-fixed cover plate 700. The ink filling port device 100 can be used to filter the ink added to the ink storage cavity 800, so that the ink stored for use by the printing device will not be mixed with impurities, thereby increasing the stability and safety of the ink printing. In combination with a stirring device 200, different stirring speeds can be adjusted according to different ink viscosities. The stirring device 200 is provided on the right side of the ink filling port device 100;

[0029] The ink filling port device 100 includes an upper ink filling port 102. A silicone pad 104 is provided at the lower end of the upper ink filling port 102. A filter 105 is embedded in the silicone pad 104 to filter the added ink. Two silicone pads 104 sandwich the filter 105 and the O-ring 103 and are fixed to the upper cover plate 701 through the through hole in the upper ink filling port 102.

[0030] The stirring device 200 includes a stepper motor 201 mounted on the top of the screw-fixed cover plate 700. The lower end of the stepper motor 201 passes through a coupling 202 and a four-blade stirring paddle 204. The four-blade stirring paddle 204 can stir the ink more fully and improve the quality of printing.

[0031] In this embodiment, preferably, an O-ring 103 is provided between the silicone pad 104 and the upper ink filling port 102 to play a sealing role, and the upper end of the upper ink filling port 102 is threadedly connected to the ink filling port cover 101.

[0032] In this embodiment, preferably, the stirring device 200 further includes a motor base 203 fixed on the upper surface of the screw-fixed cover plate 700 , and the stepping motor 201 is fixed on the upper surface of the motor base 203 .

[0033] In summary, the filter 105 in the ink filling port device 100 is firmly installed in the upper ink filling port 102. When the ink is added to the upper ink filling port 102, the fine ink passes through the filter 105 and flows to the ink storage cavity 800, while the particulate impurities mixed in the ink will be retained on the filter 105. The subsequent use of the printing equipment will not be affected by the impurities. The ink entering the ink storage cavity 800 can adjust the speed of the stepper motor 201 according to the viscosity of the ink, so that the four-blade stirring paddle 204 can maintain a suitable speed for stirring the ink, fully stir the ink, and improve the quality of printing.

[0034] Example 2

[0035] Reference Figure 4 - Figure 9 , which is the second embodiment of the present utility model, and this embodiment is different from the previous embodiment.

[0036] In this embodiment, preferably, a liquid level detection device 300, an ink outlet 400 and an ink return port 500 are vertically arranged on the upper surface of the screw-fixed cover plate 700. The ink outlet 400 is the ink supply source of the ink path system. The liquid level detection device 300 can detect three positions, namely the upper and lower limit positions and the middle position; the upper limit position is to remind people not to add too much ink when adding ink, because the upper ink filling port 102 has a filter 105, and the liquid level in the cavity is not easy to identify with the naked eye, and it is easy for ink to overflow without a signal reminder; the middle position can appropriately remind the current liquid level so that a prejudgment can be made; the lower limit position prompts that there is no ink; when each limit position is reached, there is a corresponding warning light 602 to remind, and the upper surface of the screw-fixed cover plate 700 is provided with an indicator light device 600 located on the right side of the ink outlet 400.

[0037] In this embodiment, preferably, the screw-fixed cover plate 700 includes an upper cover plate 701, and a sealing gasket 702 is embedded between the upper cover plate 701 and the ink storage cavity 800. The screw-fixed cover plate 700 carries some devices on it and seals the ink to prevent it from overflowing.

[0038] In this embodiment, preferably, the ink outlet 400 includes a joint 401 , the lower end of which is connected to an ink outlet tube 402 . The joint 401 and the ink outlet tube 402 are both threaded and fixed on the upper cover 701 .

[0039] In this embodiment, preferably, the indicator light device 600 includes a supporting sheet metal 601 fixed to the upper surface of the screw-fixed cover 700 , and a warning light 602 is provided on the upper end of the supporting sheet metal 601 , and the warning light 602 is equipped with a nut clamped on the supporting sheet metal 601 .

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
