Description

Technical field

[0001] The utility model relates to an external ink supply system for a printer. [Background Technology]

[0002] Currently, an external ink supply technology for printers is available on the market. This technology uses an external, large-capacity ink container to supply the required ink to the printer's ink cartridges, solving the problem of users frequently removing and refilling ink cartridges. However, it has been found that when the printer is used frequently or for long periods of time, it may run out of ink. The main reason is that the external ink cartridge has poor heat dissipation effect. The heat from the ink supply pump is transferred to the ink, resulting in increased ink viscosity and unstable ink delivery.

[0003] Therefore, it is necessary to make further improvements. [Utility Model Content]

[0004] The purpose of the present invention is to overcome the above problems. We provide an external ink supply system for a printer, which solves the problem that ink is affected by high temperature.

[0005] To achieve the above objectives, we provide an external ink supply system for a printer, which includes a box body with an ink area and a heat dissipation area defined therein. The ink area is located in front of the heat dissipation area, and multiple independent ink storage cavities are distributed on the left and right sides of the ink area. The heat dissipation area is provided with an ink supply pump with the same number of ink storage cavities, and each ink storage cavity is connected to an ink supply pump. The box body is provided with an air inlet grille and an air outlet grille on two opposite sides of the heat dissipation area, and a heat dissipation fan is provided in the heat dissipation area.

[0006] In one or more embodiments, the ink supply pump is connected to an ink supply tube extending out of the heat dissipation area, the ink supply tubes of each ink supply pump are bundled together, and a hole is opened on the heat dissipation area for the ink supply tube to pass through.

[0007] In one or more embodiments, a transparent viewing window is provided on the front side wall of the box body at a position corresponding to each ink storage cavity, and the ink level in the ink storage cavity can be checked through the viewing window.

[0008] In one or more embodiments, the top cover of the ink area is provided with a sealing plate, and an ink replenishing port is provided on the sealing plate corresponding to each ink storage cavity, and a sealing plug is provided on the ink replenishing port.

[0009] In one or more embodiments, the top of the heat dissipation area is open, and a cover plate is provided on the open top.

[0010] In one or more embodiments, the back side of the box body is a mounting surface, an adhesive layer is bonded to the mounting surface, and the adhesive layer is covered with release paper.

[0011] Compared with the background technology, the utility model has the following technical effects: by separating the heat dissipation area and the ink area on the box body, the ink supply pump is completely arranged inside the heat dissipation area, and the heat dissipation fan in the heat dissipation area is used to conduct away the heat, thereby avoiding heat accumulation affecting the viscosity of the ink.

[0013] Figure 2 This is a schematic diagram of the structure inside the box body of an embodiment of the present utility model. [Specific implementation method]

[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0015] Please see Figure 1-2 The present application provides an external ink supply system for a printer, which includes a box body 1 with an ink area and a heat dissipation area defined therein. The ink area is located in front of the heat dissipation area. A plurality of mutually independent ink storage cavities 2 are distributed on the left and right sides of the ink area. Each ink storage cavity can hold ink of different colors. An ink supply pump 3 is provided in the heat dissipation area with the same number as the ink storage cavities. Each ink storage cavity 2 is connected to an ink supply pump. An air inlet grille 4 and an air outlet grille 5 are respectively provided on two opposite sides of the heat dissipation area of ​​the box body 1. A heat dissipation fan 6 is provided in the heat dissipation area. When the heat dissipation fan works, cold air from the outside is drawn into the heat dissipation area, and hot air is blown out through the air outlet grille, thereby performing air circulation in the heat dissipation area to solve the problem of internal heat accumulation.

[0016] The ink supply pump 3 is connected to an ink supply tube 7 extending out of the heat dissipation area. The ink supply tubes of each ink supply pump are bundled together to facilitate pipe management and routing for users and to avoid entanglement between the ink supply tubes. A hole 8 is opened on the heat dissipation area for the ink supply tube to pass through.

[0017] A transparent viewing window 9 is provided on the front side wall of the box body 1 at the position corresponding to each ink storage cavity. The ink level in the ink storage cavity can be checked through the viewing window. When the user finds that the ink is low through the viewing window, the user can replenish the ink in time to avoid affecting the normal ink supply.

[0018] The top cover of the ink area is provided with a sealing plate 10, and an ink filling port is provided on the sealing plate corresponding to each ink storage cavity. A sealing plug 11 is provided on the ink filling port. When the user needs to fill ink, the sealing plug can be removed and ink can be filled into the ink storage cavity.

[0019] The top of the heat dissipation area is open, and a cover plate 12 is provided on the open top. When the ink supply pump or the heat dissipation fan fails or is damaged, the cover plate can be opened for replacement or repair.

[0020] The back of the box body 1 is the mounting surface, on which an adhesive layer is bonded, and the adhesive layer is covered with release paper. The user can tear off the release paper and then fix the box body on the side of the printer through the adhesive layer.

[0021] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
