技术领域technical field

本发明涉及打印机技术领域，尤其涉及一种打印机的字车装置。The invention relates to the technical field of printers, in particular to a character carriage device of a printer.

背景技术Background technique

喷墨打印机是市面上一种常见的打印机。喷墨打印机通常包括外壳、字车、字车架等部件，字车可以沿字车架做往复运动。字车上设有墨盒组件，喷墨打印机的打印方式是由墨盒组件提供墨源，在打印信号的驱动下将墨水自打印头喷嘴喷射至纸张等记录介质上来完成字符或图形的记录。Inkjet printers are a common type of printer on the market. Inkjet printers usually include parts such as a casing, a character carriage, and a character carriage, and the character carriage can reciprocate along the character carriage. There is an ink cartridge assembly on the character carriage. The printing method of the inkjet printer is that the ink cartridge assembly provides the ink source, and under the drive of the printing signal, the ink is ejected from the nozzle of the print head to the recording medium such as paper to complete the recording of characters or graphics.

现有的喷墨打印机的字车结构多采用记录头与墨盒同体设置的一体式墨盒，这种一体式墨盒在预定容量的墨水耗尽时，而记录头的电路和喷嘴并未达到其设计的使用寿命，如果将随同一体式墨盒一同报废的记录头无疑是一种很大的资源浪费，且造成环境污染，给后续环保处理带来较大的压力。The character carriage structure of the existing inkjet printers mostly adopts an integrated ink cartridge in which the recording head and the ink cartridge are arranged in the same body. When the predetermined capacity of the integrated ink cartridge is exhausted, the circuit and nozzles of the recording head do not meet the design requirements. The service life, if the recording head scrapped together with the one-piece ink cartridge is undoubtedly a great waste of resources, and causes environmental pollution, which brings great pressure to the subsequent environmental protection treatment.

为了解决上述技术问题，申请号为CN200720150923.0(授权公开号CN201052700Y)的中国实用新型专利中公开了一种《喷墨打印机》，其增加了外部储墨机构(墨水补充盒)，通过相应的墨水输运装置将墨水补充盒中的墨水输运至一体式墨盒中，其中，墨水补充盒具有马鞍状外形，并固定安装于喷墨打印机字车上，墨水输运装置固定安装于喷墨打印机字车上。墨水补充盒的墨水储存室主要部分位于喷墨打印机字车沿打印滑动方向的两侧，墨水输运装置位于喷墨打印机原有压盖下部。使用者可根据喷墨打印机墨盒的实际状况手工添加墨水至墨水补充盒内，从而在无需拆卸喷墨打印机墨盒的情况下达到调整喷墨打印机墨盒储墨容量的效果，以最大限度的避免对喷墨打印机记录头的反复拆装，以致受损。In order to solve the above technical problems, the Chinese utility model patent with the application number CN200720150923.0 (authorized publication number CN201052700Y) discloses an "ink jet printer", which adds an external ink storage mechanism (ink replenishment box), through the corresponding The ink transport device transports the ink in the ink replenishment box to the integrated ink cartridge, wherein the ink replenishment box has a saddle shape and is fixedly installed on the carriage of the inkjet printer, and the ink transportation device is fixedly installed on the inkjet printer on the word car. The main part of the ink storage chamber of the ink replenishment box is located on both sides of the carriage of the inkjet printer along the printing sliding direction, and the ink transport device is located at the lower part of the original press cover of the inkjet printer. The user can manually add ink to the ink replenishment box according to the actual condition of the inkjet printer ink cartridge, so as to achieve the effect of adjusting the ink storage capacity of the inkjet printer ink cartridge without removing the inkjet printer ink cartridge, so as to avoid the inkjet printer to the greatest extent. Repeated disassembly and assembly of the recording head of the ink printer, resulting in damage.

但上述专利中的字车装置还有一定的不足，该喷墨打印机中的墨水补充盒与一体式墨盒是采用上下组合的形式，即下面是一体式墨盒，上面是墨水补充盒，其中，一体式墨盒是沿水平方向上插设在字车内，墨水补充盒是安装在字车的外部，这种结构设置使得字车装置的整体体积较大，移动过程相对笨重，如要对一体式墨盒进行维修和更换时，需要先将墨水补充盒拆卸下来，然后再将字车的压盖打开，然后才能更换一体式墨盒，其拆装步骤较为繁琐，并且，墨水补充盒置于字车的外部也容易触碰外物损坏泄漏，存在有一定的安全隐患。However, the character car device in the above-mentioned patent still has certain shortcomings. The ink replenishment box and the integrated ink cartridge in the inkjet printer are in the form of upper and lower combination, that is, the lower part is the integrated ink cartridge, and the upper part is the ink replenishment box. The type ink cartridge is inserted into the type carriage in the horizontal direction, and the ink replenishment box is installed outside the type carriage. This structure makes the overall volume of the type carriage device larger and the moving process is relatively cumbersome. When repairing and replacing, it is necessary to disassemble the ink refill box first, and then open the cover of the carriage, and then replace the integrated ink cartridge. The disassembly and assembly steps are complicated, and the ink refill box is placed outside the carriage. It is also easy to touch foreign objects to damage and leak, and there are certain safety hazards.
