Description

Floating display device

The utility model relates to an ink cartridge for an ink jet printer, in particular to a floating display device for indicating that the ink is used up in the ink cartridge body or the ink cartridge. Background technique

In the current inkjet printers on the market, in order to indicate to the user that the ink of the ink storage container is used up, a triangular concentrating block is often formed or mounted on the ink cartridge to function as a prism, which is installed on the printer. An ink amount detecting sensor probe is mounted under the ink collecting block of the ink cartridge. When the ink in the ink cartridge runs out, the concentrating block exposes the ink surface and is illuminated by the light. The concentrating block reflects the illuminating light to the ink amount detecting sensor probe, and detects the sensor probe signal of the ink amount of the printer. The printer promptly Give tips for the ink to run out so that the user can take action. However, such a structure requires that the material for manufacturing the ink cartridge is excellent in light transmittance and high in cost, and the mold manufacturing and the process of the ink cartridge are complicated, and in actual use, the light collecting effect is not good under the condition that the external light is weak, and the prompt error is easily generated. . Utility model content

The utility model provides a floating display device which is simple in structure, easy to manufacture, and directly and correctly displayed. In order to achieve the above object, the present invention is achieved by the following technical solutions: a floating display device comprising a container for storing ink on a printer, wherein the device further comprises: a swinging shaft disposed in the container; A swing arm includes a pivot hole, and the swing arm further includes a float and a reflective surface.

Preferably, one end of the swing arm is provided with the rotating shaft hole, the other end is provided with a float, the float is connected with a reflective surface, and a reflective layer is fixed on a side of the reflective surface facing the bottom surface of the container.

Preferably, the swing arm is curved, the pivot hole is located at the center of the swing arm, one end of the swing arm is provided with a float, and the other end of the swing arm is provided with a light shielding plate; the bottom of the container is further Includes a reflective layer.

Preferably, the swing arm is made of a material that is opaque to light.

Preferably, the swing arm is made of a plastic having a smaller specific gravity than the ink.

Preferably, the bottom of the container faces the probe as a transparent or translucent material.

Preferably, the light reflecting layer is a stainless steel plate, an aluminum foil or a reflective coating.

A swing arm type floating display device manufactured according to the above scheme, when there is ink in a container for storing ink Floating on the surface of the ink, and when the ink in the container is used up, the float sinks, and there is no or less ink isolation between the reflective surface and the ink amount detecting sensor probe of the printer, and the reflective surface on the reflective surface passes through the bottom layer of the container, The ink usage detects the sensor probe signal, and the printer promptly gives a message that the ink is used up, so that the user can take measures. The scheme has higher reflection intensity than the triangular concentrating block, and has the advantages of simple structure, convenient manufacture and reliable performance. DRAWINGS

The present invention will be further described below with reference to the accompanying drawings and the swing arm type floating display device of the first embodiment.

Fig. 1 is a schematic view showing the structure of an open container 1 for storing ink. An open container 1 for storing ink in a transparent or translucent plastic is provided, and a swinging shaft 2 is provided in the container 1. Figure 2 shows a perspective view of the swing arm 3. The swing arm 3 is made of plastic having a specific gravity smaller than that of the ink. One end of the swing arm 3 has a shaft hole 4 axially connected to the swing shaft 2, and the other end of the swing arm 3 is provided with a float 5, and the float 5 is connected to a reflective surface 6 A reflective material 7 of a stainless steel plate or an aluminum foil is fixed to the side of the reflective surface 6 facing the bottom surface of the container 1, and the reflective material 7 may be coated on the reflective surface 6.

3 and 4 are schematic views showing the operation of the swing arm type floating display device of the above structure. When assembling, the pivot hole 4 of the swing arm 3 is fitted on the swing shaft 2, and the swing arm 3 is swung around the swing shaft 2. The opening of the container 1 is sealed with a plastic film 8 to form a sealed container 1 for storing ink. The container 1 is filled with ink 9, and the float 5 rises and falls with the amount of ink 9 in the container 1. When printing, when the ink 9 runs out, the reflective surface 6 is facing the probe 10 position of the ink usage sensor on the printer (shown in Figure 4). The reflection of the reflective surface 6 gives the probe 10 a signal indicating that the ink 9 has been used up.

If the entire container 1 for storing ink is not made of transparent or translucent plastic, at least the probe 10 is The bottom portion of the container 1 is made of a transparent or translucent material. Of course, the reflective surface 6 can also be provided directly on the float 5 facing the inner bottom surface of the container 1. Since the ink cartridge or ink cartridge of the container 1 for storing ink has a large number of structures, only the embodiment of the swing arm type floating display device portion of the present invention will be described.

The structure of the second embodiment of the present invention will now be described.

Fig. 5 is a front elevational view showing the ink in the container for storing ink of the present invention. It is made of an open container 10 for storing ink with a transparent or translucent plastic, and a swinging shaft 20 is provided in the container 10. The swinging shaft 20 is provided with a curved swing arm 30. The swing arm 30 swings about the swing shaft 20. One end of the swing arm 30 is provided with a float 40. The float 40 rises and falls with the amount of ink, and the other end of the swing arm 30 is provided with a light shield. The plate 50, the entire swing arm 30 is made of plastic having a specific gravity smaller than that of ink, opaque or substantially opaque. A reflective surface 60 facing the bottom surface of the container is disposed at a position near the bottom of the container 10 for storing ink. The reflective surface 60 faces the probe 70 of the printer ink amount detecting sensor, and the reflective material of the reflective stainless steel plate or aluminum foil is fixed on the reflecting surface 60. 80. The reflective material 8 may also be coated on the reflective surface 60. The opening of the container 10 is sealed with a plastic film 90 to form a sealed container 10 for storing ink. When there is ink in the container 10, the visor 5 covers the reflective surface 60, and the probe 70 does not receive a signal indicating that there is ink in the container 10.

Figure 6 is a front elevational view of the container in which the ink is stored, when there is no ink. When the ink is running out, the float 40 is lowered, and the visor 50 is moved to not cover the reflective surface 60, and the reflected light gives the probe 70 a signal indicating that the ink is about to be used up.

If the entire container 10 for storing ink is not made of transparent or translucent plastic, at least the bottom portion of the container 10 to which the probe 70 is made of a transparent or translucent material.

According to the floating display device of the present invention, when the ink in the container is used up, there is no or less ink isolation between the reflective surface and the ink amount detecting sensor probe of the printer, and the reflective light is used to detect the sensor probe signal, and the printer promptly gives A message that the ink is used up, so that the user can take action. It has high reflective intensity, simple structure, convenient manufacturing and reliable performance.

The above embodiments are merely illustrative of the invention, and are not intended to limit the invention, and various modifications and changes can be made without departing from the spirit and scope of the invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and should be defined by the claims.
