Description

Technical Field

[0001] This utility model relates to the field of printer printhead maintenance technology, and in particular to an independent intelligent maintenance device for printer printheads. Background Technology

[0002] Keeping the printer printhead moist is crucial because the nozzles are extremely small (typically only tens of micrometers). Dried ink can quickly clog the nozzles, causing broken lines, color casts, or even permanent damage to the printhead. Figure 1 As shown, Figure 1 This is a common printhead humidification method. After printing, the printhead is inserted into the humidification box. The purpose of the humidification box is to completely seal the entire printhead plate area, forming a sealed space. This sealed space effectively isolates air, greatly slowing down the ink evaporation rate and preventing the ink from drying and clumping in the nozzles. Furthermore, for humidification, the humidification box is connected to a humidification injection device, which injects humidifying fluid into the humidification box, keeping the printhead in a humid environment and thus preventing nozzle clogging. The humidification injection device is connected to the printer's control circuit board, which is connected to the printer's main power supply. The humidification injection device can only work when the printer is running. In a short period, such as two or three days, the nozzles will not clog under different electrical conditions. However, if the printer is stopped for a long time, such as during holidays like National Day or Spring Festival (which may last for more than 10 days), the nozzles are very prone to clogging. Once the nozzles are clogged, they need to be cleaned and readjusted again. Utility Model Content

[0003] Based on the above, the purpose of this utility model is to provide an independent intelligent maintenance device for printer printheads, which can independently maintain the printheads and prevent nozzle clogging.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model provides an independent intelligent maintenance device for printer printheads, including:

[0006] The nozzle humidification box is connected to a second humidification injection device and a suction device. The second humidification injection device is used to inject humidifying liquid into the nozzle humidification box, and the suction device is used to suction the nozzle humidification box. The second humidification injection device and the suction device are electrically connected to an independent intelligent circuit board, and the independent intelligent circuit board is connected to an independent power supply.

[0007] The independent intelligent circuit board controls the suction device and the second moisturizing injection device to operate at time intervals A.

[0008] Furthermore, the nozzle humidification box is also connected to a first humidification injection device, which is electrically connected to a printer control circuit board, and the printer control circuit board is electrically connected to the printer's main power supply.

[0009] Furthermore, the nozzle humidification box includes a nozzle humidification cavity, and two sets of connection holes are provided on the side of the nozzle humidification box, the connection holes communicating with the nozzle humidification cavity.

[0010] The beneficial effects of this utility model are as follows:

[0011] This utility model provides an independent intelligent maintenance device for printer nozzles. When the entire printer is stopped for a long time, the independent intelligent maintenance device for printer nozzles does not stop working and is powered on. The independent power supply and independent intelligent circuit board of the independent intelligent maintenance device for printer nozzles are independent and separate from the printer control circuit board and the printer main power supply. The independent intelligent circuit board can control the second moisturizing injection device and the suction device. The independent intelligent circuit board controls the suction device to perform a suction action and inject moisturizing liquid once every A time, thereby preventing nozzle clogging caused by prolonged printer stoppage.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.
