Description

Technical Field

[0001] This utility model relates to the field of two-stage ink cartridge technology, specifically a two-stage ink cartridge with integrated liquid level sensing. Background Technology

[0002] Most commercially available ink level sensors use a float-type sensor inserted into the ink cartridge to detect ink levels. However, because the sensor is in prolonged contact with the ink, this method can easily lead to ink contamination and affect print quality. Furthermore, replacing the level sensor requires disassembling the ink cartridge, making maintenance and replacement cumbersome. Utility Model Content

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-4 The integrated liquid level sensing secondary ink cartridge includes an injection-molded ink cartridge 1. Two sensor protective covers 2 are installed on the injection-molded ink cartridge 1. An upper liquid level sensor 15 and a lower liquid level sensor 16 are respectively installed inside the two sensor protective covers 2. Four limit blocks 5 are provided on the injection-molded ink cartridge 1. The two sensor protective covers 2 are respectively arranged between the two limit blocks 5. The sensor protective covers 2 are connected and fixed to the limit blocks 5 by a locking mechanism.

[0023] By using a non-contact external mounting method between the upper liquid level sensor 15 and the lower liquid level sensor 16 and the injection molded ink cartridge 1, the sensors are prevented from contaminating the ink and affecting the printing quality. Furthermore, protective covers are installed on the outside of the upper liquid level sensor 15 and the lower liquid level sensor 16 to prevent external impacts and dust contamination from affecting the sensor's performance.

[0024] Specifically, in this embodiment, four limiting blocks 5 are distributed at intervals along the vertical direction to facilitate the restriction of the position of the two sensor protective covers 2.

[0025] Specifically, in this embodiment, the limiting block 5 has a groove 3, and the sensor protective cover 2 has two symmetrical protrusions 4, the size of which is adapted to the groove 3.

[0026] The installation position of the sensor protective cover 2 can be restricted by the setting of the groove 3 and the protrusion 4.

[0027] Specifically, in this embodiment, the protrusion 4 has a through hole 6, and a fixing bolt can be inserted into the through hole 6. The fixing bolt can be inserted through the protrusion 4 to connect with the injection molded ink cartridge 1, thereby achieving the purpose of locking and fixing the sensor protective cover 2.

[0028] Specifically, in this embodiment, the locking mechanism includes two reset grooves 7 formed on the sensor protective cover 2. A reset slider 9 is slidably arranged in the reset groove 7. A limiting rod 10 is protruding on the reset slider 9. A slot 11 adapted to the limiting rod 10 is formed on the limiting block 5. After the sensor protective cover 2 is connected between the two limiting blocks 5, the limiting rod 10 on the reset slider 9 is inserted into the slot 11 on the limiting block 5 by moving the reset slider 9, thereby realizing the connection and fixation between the sensor protective cover 2 and the limiting block 5.

[0029] Specifically, in this embodiment, a reset spring 8 is provided in the reset groove 7. One end of the reset spring 8 abuts against the inner wall of the reset groove 7, and the other end of the reset spring 8 abuts against the reset slider 9.

[0030] By setting the reset spring 8, the reset slider 9 can be pressed against the inner wall of the reset groove 7 without manual action, thereby ensuring that the limit rod 10 is always pressed against the slot 11, thus ensuring the connection stability between the sensor protective cover 2 and the limit block 5.

[0031] Specifically, in this embodiment, a rectangular sliding hole 14 communicating with the outside is provided on the inner wall of the reset slide groove 7, and an adjustment block 12 protrudes from the reset slider 9, passing through the rectangular sliding hole 14 and extending to the outside. Multiple anti-slip grooves 13 are provided on the adjustment block 12 at intervals along the axial direction. The reset slider 9 can be driven to slide in the reset slide groove 7 by moving the adjustment block 12.

[0032] It should be noted that the selection of the upper and lower liquid level sensors, springs, and other standard parts are all common knowledge in this field, and will not be elaborated upon here.
