Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a detachable ink filtering device. Background Art

[0002] Ink filters are crucial components used in inkjet printers, photo printers, and other devices. They are primarily responsible for delivering ink and ensuring smooth and stable flow. They are typically made of corrosion-resistant materials, such as composite tubing, to prevent contamination or clogging of the ink as it flows through the pipes. These pipes also possess a degree of flexibility and durability to accommodate the needs of different devices and environments. Ink filters come in a variety of sizes and specifications, such as 32, 42, and 64 mm, to meet the needs of different models and brands of inkjet printers. In addition, there are ink filters specifically designed for UV inks, which typically offer higher corrosion resistance and durability.

[0003] The present application is an improvement on the existing technology. In the existing technology, in order to achieve the purpose of filtering ink, all color group ink guide tubes are now filtered by silk stockings. The advantage is that the filtering effect is good, but the silk stockings need to be purchased frequently. The silk stockings need to be replaced every time the ink is changed. The frequent replacement causes waste of manpower and silk stockings, and has low practicality.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application, and should not be regarded as an admission or any form of implication that the information constitutes the prior art already known to ordinary technicians in this field. Utility Model Content

[0005] The purpose of the present invention is to provide a detachable ink filter device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a detachable ink filter device, comprising an ink filter tube body, wherein the lower surface of the ink filter tube body is provided with a threaded groove connected to the interior thereof, a hollow threaded column is threadedly connected to the inner wall of the threaded groove, a rotating cover is fixedly connected to the bottom of the hollow threaded column, a mounting hole is formed through the surface of the rotating cover, and a stainless steel filter screen is arranged inside the mounting hole.

[0007] As a further solution of the present invention: the mesh number of the stainless steel filter is 200.

[0008] As a further solution of the present invention: the outer wall of the rotating cover is provided with a plurality of anti-slip protrusions in a ring array, and the anti-slip protrusions are made of rubber material.

[0009] As a further solution of the present invention: an internal thread is provided on the inner wall of the thread groove, and an external thread that matches the thread groove is provided on the outer wall of the hollow threaded column.

[0010] As a further solution of the present invention: a convex buckle is provided on the top of the ink filter tube body, and the convex buckle is made of stainless steel.

[0011] The utility model has the following beneficial effects:

[0012] (1) Through the structural design of the rotating cover, the mounting hole, the stainless steel filter, the threaded groove and the hollow threaded column, the ink can be filtered through the stainless steel filter, and the stainless steel filter is easy to disassemble, clean and install, so that it can be recycled, reducing costs and having high practicality. It solves the problem that in order to achieve the purpose of filtering ink, all color group ink guide tubes currently use silk stockings for filtering, which has the advantage of good filtering effect, but requires frequent purchase of silk stockings, and each time the ink is changed, the silk stockings need to be replaced, and the frequent replacement causes waste of manpower and silk stockings, and has low practicality;

[0013] (2) By setting the anti-skid protrusions and the convex buckles, the anti-skid protrusions can cooperate with each other to facilitate the user to twist and turn the cover better. At the same time, by setting the convex buckles, it is easier to snap into the concave buckles at the bottom of the ink outlet of the ink tank, thereby facilitating the disassembly and assembly of the ink filter tube, and further facilitating the replacement of the stainless steel filter.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0020] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0021] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate and simplify the description of the utility model and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the utility model. Furthermore, the terms "first," "second," and "third," etc., are used solely for distinction and description and should not be construed as indicating or implying relative importance.

[0022] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.
