Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of inkjet printers, in particular to a detection mechanism for the ink cartridge solvent transmission pipeline of an inkjet printer. Background Art
[0002] The solvent of an inkjet printer is also called a diluent or a dilution liquid, and the selection of its components directly affects the performance of the ink and the printing effect. Solvents play an important role in inkjet printers. Their main function is to adjust the viscosity of the ink to ensure that the ink can smoothly pass through the nozzles of the inkjet printer for printing. Traditional inkjet printer solvents are conductive, and the prior art uses the conductive property of the solvent for detection. However, more and more inkjet printers are starting to add new non-conductive solvents, and the traditional detection method can no longer detect non-conductive solvents. Therefore, it will lead to the failure to replace the solvent in time, resulting in high ink viscosity, blurred typing and other phenomena. Summary of the Utility Model
[0003] The technical problem to be solved by the embodiments of the utility model is to provide a detection mechanism for the ink cartridge solvent transmission pipeline of an inkjet printer to detect whether there is solvent in the transmission pipeline for adding solvent to the ink cartridge.
[0004] To solve the above technical problem, the embodiments of the utility model propose a detection mechanism for the ink cartridge solvent transmission pipeline of an inkjet printer, including a transparent tube. Pipe joints are provided at both the front and rear ends of the transparent tube, and a photoelectric sensor for detecting whether there is solvent in the transparent tube is provided on the transparent tube.
[0005] Further, the transparent tube is a transparent Teflon tube.
[0006] Further, the pipe joint is a metal pipe joint.
[0007] The beneficial effect of the utility model is that the structure of the utility model is simple. It can be directly applied to the solvent transmission pipeline of the existing inkjet printer through the pipe joint. The optical detection is converted into an electrical signal output through the photoelectric sensor, which can detect non-conductive solvents in real time, accurately detect the presence or absence of solvents, and facilitate users to replace the new solvent ink cartridge in time.

[0011] Description of the Attached Drawing Reference Numerals
[0012] Transparent tube 1, pipe joint 2, photoelectric sensor 3. Specific Embodiment
[0013] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following further describes the present utility model in detail with reference to the drawings and specific embodiments.
[0014] In the embodiments of the present utility model, if there are directional indications (such as up, down, left, right, front, back...), they are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, the directional indications will also change accordingly.
[0015] In addition, in the present utility model, the descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.
[0016] Please refer to Figures 1 to 3 , the ink cartridge solvent transmission pipeline detection mechanism of the inkjet printer in the embodiment of the present utility model includes a transparent tube. Pipe joints are provided at both the front and rear ends of the transparent tube. A photoelectric sensor for detecting whether there is solvent in the transparent tube is provided on the transparent tube. The pipe joint is hollow and is used to connect the solvent transmission pipeline of the existing inkjet printer. The pipe joint can directly adopt the existing common structure, that is, the two ends of the pipe joint are respectively matched with the transparent tube and the solvent transmission pipeline (specifically, the outer diameters of the two ends of the pipe joint are respectively matched with the inner diameters of the transparent tube and the solvent transmission pipeline).
[0017] The light emitting end of the photoelectric sensor emits light signals with a specific wavelength. These light signals pass through the transparent tube. When there is solvent in the transparent tube, the light signals will be absorbed or reflected by the solvent. When the solvent does not exist, the light signals will directly irradiate onto the light receiving end (photodiode) of the photoelectric sensor, and the photoelectric sensor feeds back signals to the upper computer.
[0018] As an implementation manner, the transparent tube is a transparent Teflon tube.
[0019] As an implementation manner, the pipe joint is a metal pipe joint.
[0020] The photoelectric sensor of the present utility model is installed on the transparent Teflon tube. When a non-conductive solvent passes through, the electrical signal output ground wire is closed at this time. When a non-conductive solvent passes through, the electrical signal output ground wire is disconnected at this time, and it will display that the solvent ink cartridge is empty according to the feedback information, and the solvent ink cartridge can be replaced in time. The present utility model solves the problem of detecting non-conductive solvent ink cartridges, and has a small volume and simple installation.
[0021] Although the embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the appended claims and their equivalents.
