Pressure dynamic compensation device and continuous ink supply system using pressure dynamic compensation

Abstract

The invention relates to a pressure dynamic compensation device and a continuous ink supply system using pressure dynamic compensation. The pressure dynamic compensation device comprises a pressure dynamic compensation container (7) and an elastic air bag (73), wherein the elastic air bag (73) is arranged inside the pressure dynamic compensation container (7), an opening of the elastic air bag (73) is in sealed connection with a connector of the container and communicated with the atmosphere, a compensation port (72) and an air inlet (76) are arranged on the pressure dynamic compensation container (7), an air inlet inner cover which corresponds to the position of the air inlet (76) is connected with the bag body of the elastic air bag (73) directly or indirectly. According to the pressure dynamic compensation device and the continuous ink supply system using pressure dynamic compensation, the chance that ink contacts with the outside air is reduced effectively, also the probabilities of oxidation, evaporation and crystallization of ink are reduced so that a phenomenon that heads are blocked is reduced; small bubbles of the ink disappear gradually due to discontinuous negative pressure of an ink storage barrel so as to solve phenomenon that air is blocked; and the problem that the ink flows out of an ink box and flows back to the ink box is solved.

Description

technical field [0001] The invention relates to a pressure dynamic compensation device and a pressure dynamic compensation continuous ink supply system, in particular to a pressure dynamic compensation device and a pressure dynamic compensation continuous ink supply system of an inkjet printer. It belongs to the field of printing technology. Background technique [0002] The continuous ink supply system, referred to as continuous supply, is a new ink supply method that has only appeared in the field of inkjet printers in recent years. The continuous ink supply system uses an external ink bottle to connect to the ink cartridge of the printer with a conduit, so that the ink bottle provides ink to the ink cartridge continuously. The biggest advantage of the continuous ink supply system is that it is affordable, and the price is much cheaper than the original ink. Secondly, the ink supply is large, and it is convenient to add ink. Generally, the capacity of one color is 100ml,...

Problems solved by technology

[0003] However, in the existing continuous ink supply system, the air plug of the ink storage container is connected to the atmosphere for a long time, which is prone to oxidation, resulting in crystallization and precipitation. When the water level of the printing ink cartridge is higher than the external water level, the ink will flow back. The ink level is higher than the ink cartridge level, and the ink will flow into the print through the ink supply duct

Over a long period of time, it is easy to have air resistance, head resistance, ink flying, and even damage to the print head or printer
