Description

Technical Field

[0001] This utility model belongs to the field of digital inkjet printing technology, specifically relating to an inkjet head anti-clogging and moisture-retaining component for a digital inkjet printer. Background Technology

[0002] A digital inkjet printer is a device that uses inkjet technology to print. It uses digital control to spray ink onto the printing medium. The working principle of digital inkjet printing is to spray liquid ink droplets from tiny inkjet heads to form images or text on the printing medium. Therefore, any blockage may lead to a decrease in print quality or equipment failure, so effective maintenance and humidification are required.

[0003] For example, a Chinese patent discloses an anti-clogging and moisturizing structure for the inkjet head of a digital inkjet printer (publication number CN222538535U). This patented technology solves the problem in the prior art that after the inkjet head of a digital inkjet printer is used, the ink remains inside the inkjet head. When the printer is not used for a long time, the ink will dry out due to moisture loss, affecting subsequent inkjet printing and easily causing damage to the printer.

[0004] However, most existing digital inkjet printers use a method of directly immersing the inkjet head in a humidification chamber to prevent clogging and maintain moisture. Because the ink inside the inkjet head may solidify, this immersion method cannot remove the ink quickly enough, affecting usability. As mentioned in the comparative document above, this method involves immersing the inkjet head. In practical applications, the ink inside the inkjet head may solidify in the later stages of inkjet printing, making immersion alone insufficient to prevent clogging, and clogging may still occur.

[0005] Therefore, those skilled in the art have provided an inkjet head anti-clogging and moisture-retaining component for a digital inkjet printer to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide an inkjet head anti-clogging and moisture-retaining component for a digital inkjet printer, which can solve the problems mentioned in the background art.

[0007] The specific technical solution adopted in this utility model is as follows:

[0008] A printhead anti-clogging and moisture-retaining component for a digital inkjet printer includes a water tank and a connecting plate installed on one side of the water tank. A moisture-retaining box is slidably mounted on the upper surface of the connecting plate. A water inlet plate is provided inside the moisture-retaining box. Printheads are symmetrically arranged on the upper surface of the water inlet plate. A filter box is installed on one side of the water tank. Return water pipes are symmetrically arranged on the lower surface of the filter box. A filter plate is inclinedly arranged inside the water tank. A filter screen is installed on one side of the filter plate inside the filter box.

[0009] The present invention is further configured such that: a cylinder is installed on one side of the water tank above the connecting plate, and the telescopic end of the cylinder is connected to one side of the humidification box.

[0010] The present invention is further configured such that: the upper surface of the connecting plate is symmetrically provided with guide rails, and the lower surface of the humidifying box is provided with guide grooves that slide relative to the guide rails.

[0011] The present invention is further configured such that: a liquid pump is installed inside the water tank, the outlet end of the liquid pump is connected to a water pumping pipe, one end of the water pumping pipe is connected to a first flexible hose, and one end of the first flexible hose is connected to the interior of the humidifying box.

[0012] The present invention is further configured such that: a second hose is connected to one side of the humidifying box, and a drain pipe is connected to one end of the second hose, with the outlet end of the drain pipe located above the filter plate.

[0013] The present invention is further configured such that: two sets of return water pipes are symmetrically arranged on the lower surface of the filter box, and the filter box and the water tank are interconnected.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This utility model relates to an anti-clogging and moisturizing component for the inkjet printer head. It utilizes a pump inside a water tank to draw water from the tank and guide it through a suction pipe and a first flexible hose into the water inlet plate. The water is then sprayed outwards through the printhead to clean the inkjet printer head, improving its anti-clogging and moisturizing effect. This design is highly practical.

[0016] This utility model relates to an inkjet printer head anti-clogging and humidification component. Through a second hose and a drain pipe, water in the humidification box can be recycled to a water tank.

[0022] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1 As shown, a printhead anti-clogging and humidification component for a digital inkjet printer includes a water tank 1 and a connecting plate 3 installed on one side of the water tank 1. A humidification box 4 is slidably mounted on the upper surface of the connecting plate 3. A water inlet plate 41 is provided inside the humidification box 4. Printheads 411 are symmetrically arranged on the upper surface of the water inlet plate 41. A filter box 2 is installed on one side of the water tank 1. A return water pipe 21 is symmetrically arranged on the lower surface of the filter box 2. A filter plate 11 is inclinedly arranged inside the water tank 1. A filter screen 22 is installed on one side of the filter plate 11 inside the filter box 2. This arrangement is achieved by the operation of a cylinder 5. The humidifier box 4 can be moved to the position of the digital inkjet printer and positioned below the inkjet head. The pump 422 inside the water tank 1 can draw water from inside the tank and enter the water inlet plate 41 through the water inlet pipe 421 and the first hose 42. Finally, the water is sprayed out through the printhead 411 to clean the inkjet head and prevent it from clogging. As water is continuously sprayed, the water inside the humidifier box will exceed the water inlet plate 41. When the inkjet head is turned down, it will enter the humidifier box 4 and enter the water. This can effectively prevent the inkjet head from clogging and keep it moisturized.

[0024] like Figure 1 and Figure 2 As shown, a cylinder 5 is installed on one side of the water tank 1 above the connecting plate 3. The telescopic end of the cylinder 5 is connected to one side of the humidification box 4. Guide rails are symmetrically arranged on the upper surface of the connecting plate 3, and guide grooves that slide against the guide rails are opened on the lower surface of the humidification box 4. This arrangement utilizes the operation of the cylinder 5 symmetrically arranged on one side of the water tank 1 to move the humidification box 4 on the connecting plate 3 toward the position of the digital inkjet printer. At the same time, the guide rails guide the movement inside the guide grooves, thus ensuring the stability of the movement of the humidification box 4.

[0025] like Figure 3As shown, a liquid pump 422 is also installed inside the water tank 1. The outlet end of the liquid pump 422 is connected to a water suction pipe 421. One end of the water suction pipe 421 is connected to a first flexible hose 42. One end of the first flexible hose 42 is connected to the interior of the humidification box 4. This setup uses the operation of the liquid pump 422 to draw water from inside the water tank 1 and enter the water inlet plate 41 through the water suction pipe 421 and the first flexible hose 42. After entering, the water is sprayed out through the printhead 411 to clean and prevent the inkjet head from clogging.

[0026] like Figure 3 and Figure 4 As shown, a second hose 61 is also connected to one side of the humidifying box 4. One end of the second hose 61 is connected to a drain pipe 6. The outlet end of the drain pipe 6 is located above the filter plate 11. This arrangement allows the water inside the humidifying box 4 to be drained through the second hose 61 and enter the water tank 1 through the drain pipe 6 to achieve the purpose of filtration and recycling. A valve is provided at the connection between the second hose 61 and the humidifying box 4 to open and close.

[0027] like Figure 3 As shown, two sets of return water pipes 21 are symmetrically arranged on the lower surface of the filter box 2. The filter box 2 and the water tank 1 are interconnected. This arrangement allows the impurities filtered by the filter plate 11 to be tilted and fed onto the filter screen 22 for collection and filtration. The water can be drained through the drain holes on the filter screen 22 and returned to the water tank 1 through the return water pipes 21 to achieve the purpose of recycling.

[0028] The working principle of this utility model is as follows: When using the inkjet head anti-clogging and moisturizing component for a digital inkjet printer, water for cleaning the inkjet head first enters the water tank 1 through the inlet pipe. After entering, the operation of cylinder 5 causes the moisturizing box 4 to slide above the connecting plate 3, thus sending the moisturizing box 4 under the inkjet head on the digital inkjet printer. Once in position, the operation of pump 422 extracts water from the water tank 1 and sends it through pump pipe 421 and the first flexible hose 42 into the inlet plate 41. After entering, the water is sprayed out through the printhead 411 to clean and prevent clogging of the inkjet head. The purpose is to ensure that, as water is continuously sprayed, the water level inside the humidifier box 4 exceeds the water inlet plate 41. At this time, when the inkjet head is turned downwards, it will enter the humidifier box 4 and enter the water. This can effectively prevent the inkjet head from clogging and keep it moisturized. After the clogging and moisturizing are completed, the valve on the outside of the second hose 61 can be opened to drain the water inside the humidifier box 4 and enter the water tank 1 through the drain pipe 6. After entering, the impurities filtered by the filter plate 11 are tilted and fed onto the filter screen 22 for collection and filtration. The water can be drained through the drain holes on the filter screen 22 and returned to the water tank 1 through the return water pipe 21 to achieve the purpose of recycling, reducing costs and improving practicality.
