Abstract

[Problem] There is a risk of waste liquid leaking at the connection point between the waste liquid container and the inlet. [Solution] The liquid dispensing device 1 comprises a dispensing unit 10 for dispensing ink, a waste liquid container 80 for containing the ink as waste liquid, and a mounting unit 60 for mounting the waste liquid container 80. The mounting unit 60 is an introduction unit 70 that can be inserted into the waste liquid container 80 along the X axis, and has an introduction unit 70 for introducing ink into the waste liquid container 80, and a holding unit 65 for holding the introduction unit 70. The introduction unit 70 is held by the holding unit 65 in a state that it can move along the Y-Z plane perpendicular to the X axis. [Selection Diagram] Figure 1

Description

This disclosure relates to a liquid dispensing device. Patent Document 1 discloses a waste liquid container that is detachably mounted in a mounting chamber of a liquid injection device, which comprises a discharge section for discharging liquid discharged as waste liquid from a liquid injection head, and a mounting chamber in which the discharge section is located. The wall of the waste liquid container is provided with a waste liquid introduction section that connects to the discharge section as the waste liquid container moves in the connection direction, allowing waste liquid to be introduced into the waste liquid container. The positions of the sealing member constituting the waste liquid introduction section and the discharge section are defined by a guide section provided on the waste liquid container being guided by a guide projection provided in the mounting chamber. Japanese Patent Publication No. 2020-196271 A schematic plan view showing the general configuration of a liquid dispensing device according to an embodiment.A perspective view showing the configuration of a waste liquid container according to the embodiment.A perspective view showing the configuration of an absorbent contained in a waste liquid container according to the embodiment.A perspective view showing the configuration of the mounting section to which the waste liquid container according to the embodiment is attached.A perspective view showing the configuration of the introduction section according to the embodiment.A perspective view showing the configuration of the holding part according to the embodiment.A perspective view showing the introduction portion held by the holding portion according to the embodiment.A perspective view showing a waste liquid container attached to a mounting part according to the embodiment.A cross-sectional view showing the S9-S9 section shown in Figure 1.A partial cross-sectional view showing the area around the inlet inserted into the hole of the waste liquid container at the mounting location.A partial perspective view showing the area around the inlet inserted into the hole of the waste liquid container at the mounting position. The following description is based on embodiments. In each figure, identical components are denoted by the same reference numerals, and redundant descriptions may be omitted. As used herein, "same," "identical," and "simultaneous" do not necessarily mean exactly the same. For example, in this specification, the terms "same," "identical," and "simultaneous" include cases where measurement errors are taken into consideration. Furthermore, for example, in this specification, the terms "same," "identical," and "simultaneous" include cases where manufacturing variations of the components are taken into consideration. In this specification, the terms "same," "identical," and "simultaneous" include cases where the same is true without impairing the function. Therefore, for example, "the dimensions of both are the same" means that, considering measurement errors and manufacturing variations of the components, the dimensional difference between the two is within ±5 percent, and particularly preferably within ±3 percent, of the dimension of one of them. In each figure, X, Y, and Z represent three mutually orthogonal spatial axes. In this specification, the directions along these axes are referred to as the X-axis direction, Y-axis direction, and Z-axis direction. When specifying directions, a positive direction is denoted as "+" and a negative direction as "-". Positive and negative signs are used in the direction notation, and the direction indicated by the arrow in each figure is described as the + direction, and the opposite direction is described as the - direction. The Z-axis direction indicates the direction of gravity, the +Z direction indicates vertically upward, and the -Z direction indicates vertically downward. A plane containing the X and Y axes is described as the X-Y plane, a plane containing the X and Z axes is described as the X-Z plane, and a plane containing the Y and Z axes is described as the Y-Z plane. The X-Y plane is the horizontal plane. The three spatial axes X, Y, and Z, without specifying positive or negative directions, are described as the X-axis, Y-axis, and Z-axis. The X-axis direction is horizontal along the installation surface, which is the horizontal plane on which the liquid dispensing device 1 is installed. The X-axis direction is the width direction of the paper P being transported by the liquid dispensing device 1. The Y-axis direction is horizontal along the installation surface on which the liquid dispensing device 1 is installed. The Y-axis direction is the transport direction of the paper P being transported by the liquid dispensing device 1. The Z-axis direction is the normal direction to the installation surface on which the liquid dispensing device 1 is installed, and is the height direction of the liquid dispensing device 1. In the fo
