Mounting structure, module and liquid container

Abstract

The mounting structure for mounting the piezo-electric device (106) used to detect the consumption condition of the liquid in the liquid container (1) to the liquid container (1), having the receiving portion (363) to which the piezo-electric device (106) is to be mounted and the mount portion (363) to be mounted to the liquid container (1). The mounting structure can appropriately mount a piezo-electric device (106) for detecting the consumption condition of a liquid in a liquid container (1) to the liquid container (1).

Description

technical field [0001] The present invention relates to a mounting structure for mounting a piezoelectric device on a liquid container, a module having the mounting structure and the piezoelectric device, and a liquid container having the module and a container body. The piezoelectric device detects the liquid consumption state in the liquid container containing the liquid by detecting the change of the acoustic impedance, especially by detecting the change of the resonant frequency therein. Background technique [0002] Next, a conventional liquid container will be described by taking an ink cartridge mounted on an ink jet recording apparatus as an example. In general, an inkjet recording device has: a pressure generating device for pressurizing a pressure generating chamber, a carriage on which an inkjet recording head is mounted, and an ink tank containing ink supplied to the recording head through a flow path. The head is equipped with nozzle openings for ejecting press...

Problems solved by technology

[0004] However, the method of using software to accumulate the number of ink droplets ejected or the amount of sucked ink and calculate and control the ink consumption will cause the following problems: depending on the use environment, such as the temperature in the use room or the level of the temperature, the time elapsed after the ink cartridge is opened, The pressure in the ink cartridge or the viscosity of the ink will change due to the difference in the frequency of use within the user, resulting in a non-negligible error between the calculated ink consumption and the actual consumption.

However, in order to detect the liquid level of the ink, the ink must be conductive, which limits the type of ink used, and also brings about the problem of a complicated liquid-tight structure between the electrode and the ink cartridge.

In addition, as an electrode material, a noble metal with good conductivity and high corrosion resistance is generally used, so there is also a problem that the manufacturing cost of the ink cartridge increases.

Moreover, since the two electrodes must be respectively installed in other places of each ink cartridge, the manufacturing process is numerous, and as a result, the problem that the manufacturing cost is too high has also been brought.

[0006] In addition, in the above-mentioned method of controlling the time consumption by the electrodes, holes for mounting the electrodes on the ink cartridge must be provided on the ink cartridge

Therefore, the injection molding process is complicated when making ink cartridges from plastic

[0007] In addition, in order to maintain liquid tightness, the electrode needs to have a special sealing structure, so that it is difficult to separate the electrode from the ink cartridge

As a result, the exchange or recycling of electrodes and ink cartridges is difficult
