The FPC cable is used to establish a signal connection between the TPH printhead and the printer motherboard, while the IC components communicate with the printer motherboard via the FPC cable, providing encrypted information so that the manufacturer / retailer can trace and maintain the sold TPH printhead assemblies.

[0003] Currently, after prolonged use, existing printhead components typically require regular cleaning of the printhead nozzles by staff. However, because the printhead nozzles are located inside the equipment, it is difficult for staff to clearly see the cleaning status of the nozzles during cleaning, thus reducing the convenience of printhead cleaning. Utility Model Content

[0004] The purpose of this utility model is to provide a convenient way to clean printhead assembly components. It aims to solve the problem that after long-term use, existing printhead assembly components usually require regular cleaning of the printhead nozzles by staff. However, since the printhead nozzles are located inside the equipment, it is difficult for staff to see the cleaning status of the printhead nozzles during cleaning, thus reducing the convenience of printhead cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient printer nozzle assembly component, including a printer nozzle plate, a reflector rotatably connected to the bottom of the printer nozzle plate, a rotating shaft connected to one end of the reflector, two connecting seats connected to one end of the reflector, a return spring provided inside the two connecting seats, a movable block connected to one end of the return spring, a limit pin connected to one end of the movable block, a pull rod connected to one end of the movable block, and two fixing blocks connected to the bottom of the printer nozzle plate, with limit slots formed on the outer walls of the two fixing blocks.

[0006] As a preferred component of the present invention for facilitating the cleaning of a printhead assembly, the two connecting seats are symmetrically distributed.

[0007] As a preferred component of the present invention for facilitating the cleaning of a printhead assembly, the dimensions of the limiting slot and the limiting pin are mutually compatible.

[0008] As a preferred component of the present invention for a conveniently cleanable printhead assembly, the two ends of the pull rod are respectively inserted into a connecting seat.

[0009] As a preferred component of the printer nozzle assembly for easy cleaning according to this utility model, the two fixing blocks are symmetrically distributed.

[0010] As a preferred component of the present invention for easy cleaning of a printhead assembly, one end of the limiting pin extends through the connecting seat to the outside.

[0011] As a preferred component of the present invention for easy cleaning of the printhead assembly, one end of the reflector can form an elastic engagement structure with the printhead plate through a connecting seat, a return spring, a movable block, a limit pin, a pull rod, a fixing block, and a limit slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Pulling the lever moves the movable block, causing the limit pin to retract. At this time, one end of the limit pin will disengage from the limit slot on the outer wall of the fixed block. Then, the reflector is flipped over by the rotating connection structure between the reflector and the print head plate, so that one end of the reflector opens downwards. The reflector can reflect light to illuminate the print head at the bottom of the print head plate, making it easier for staff to clean the print head. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides the following technical solution: a convenient printer nozzle assembly component, including a printer nozzle plate 1, a reflector plate 2 rotatably connected to the bottom of the printer nozzle plate 1, a rotating shaft 3 connected to one end of the reflector plate 2, two connecting seats 4 connected to one end of the reflector plate 2, a return spring 5 provided inside the two connecting seats 4, a movable block 6 connected to one end of the return spring 5, a limit pin 7 connected to one end of the movable block 6, a pull rod 8 connected to one end of the movable block 6, and two fixing blocks 9 connected to the bottom of the printer nozzle plate 1, with limit slots 10 formed on the outer walls of the two fixing blocks 9.

[0023] Preferably, the two connecting seats 4 are symmetrically distributed, the size of the limiting slot 10 and the limiting pin 7 are matched, the two ends of the pull rod 8 are respectively inserted into the interior of a connecting seat 4, and the two fixing blocks 9 are symmetrically distributed.

[0024] In practical use, the movable block 6 is pulled by the lever 8 to cause the limiting pin 7 to retract. At this time, one end of the limiting pin 7 will disengage from the limiting slot 10 on the outer wall of the fixed block 9. Then, the reflector 2 is flipped over by the rotating connection structure between the reflector 2 and the print head plate 1 so that one end of the reflector 2 opens downward. At this time, the reflector 2 can reflect light to illuminate the print head at the bottom of the print head plate 1.

[0025] Preferably, one end of the limiting pin 7 passes through the connecting seat 4 and can extend to the outside, and one end of the reflector 2 can form an elastic engagement structure with the print head plate 1 through the connecting seat 4, the return spring 5, the movable block 6, the limiting pin 7, the pull rod 8, the fixing block 9, and the limiting slot 10.

[0026] In practical use, the movable block 6 is pulled by the lever 8 to cause the limit pin 7 to retract. Then, the reflector 2 is flipped up and closed by the rotating connection structure between the reflector 2 and the print head plate 1. When the connecting seat 4 is parallel to the movable block 6, the lever 8 is released, so that the limit pin 7 can pop out and insert into the limit slot 10 under the action of the return spring 5, thereby realizing the closing and fixing of the reflector 2.

[0027] Working principle: First, when the printhead at the bottom of the printhead plate 1 needs to be cleaned, the movable block 6 is pulled by the lever 8, causing the limiting pin 7 to retract. At this time, one end of the limiting pin 7 will disengage from the limiting slot 10 on the outer wall of the fixed block 9. Then, the reflector 2 is flipped by the rotating connection structure between the reflector 2 and the printhead plate 1, so that one end of the reflector 2 opens downward. At this time, the reflector 2 can reflect light to illuminate the printhead at the bottom of the printhead plate 1, thus facilitating the cleaning of the printhead. The movable block 6 is pulled by the lever 8, causing the limiting pin 7 to retract. Then, the reflector 2 is flipped by the rotating connection structure between the reflector 2 and the printhead plate 1 to close upward. When the connecting seat 4 is parallel to the movable block 6, the lever 8 is released, so that the limiting pin 7 can pop out and insert into the limiting slot 10 under the action of the return spring 5, thereby realizing the closing and fixing of the reflector 2.

[0028] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
