Problems solved by technology

[0005] Whether it is the valve body itself made of rubber materials or the spring made of metal materials, there are fatigue problems. From the perspective of processing technology, it is also difficult to control their elastic recovery force within an acceptable tolerance range. They are all arranged in the fluid channel, and the elastic recovery forc

Example

[0025] First embodiment:

[0026] see image 3 , this example is a valve assembly, the valve body 300 is located in the valve chamber formed by the combination of the valve holder 200 and the valve cover 100, the valve chamber has an inlet 101 and an outlet 201, wherein the valve cover 100 and the valve body 100 are both made of a magnetic system The inlet surface 102 is opposite to the valve surface 303 with opposite magnetic poles. Under the action of magnetic attraction, the valve surface 303 is attracted to the inlet surface to block the fluid channel between the inlet 101 and the outlet 201 . When the valve assembly is connected in series in a fluid channel, the pressure at the inlet 101 is high and the pressure at the outlet 201 is low, and the pressure difference is greater than the magnetic attraction force, the valve body 300 will go down under the pressure difference, opening the inlet 101 and the outlet 201. Fluid passage between outlets 201.

Example

[0027] Second embodiment:

[0028] see Figure 4 , this example is also a valve assembly, the valve body 300 is located in the valve chamber formed by the combination of the valve holder 200 and the valve cover 100, the valve chamber has an inlet 101 and an outlet 201, the valve body 100 is made of a magnetic body, and another magnetic body 402 Fixed on the bottom surface of the valve holder 200, the magnetic body 400 has a through hole 401 docked with the outlet 201, the upper surface of the magnetic body 400 is opposite to the lower surface 304 of the valve body 300 with the same magnetic polarity, and the repulsive force between the two makes the valve surface 303 is closely attached to the inlet surface 102 to block the fluid channel between the inlet 101 and the outlet 201 . When the valve assembly is connected in series in a fluid channel, the pressure at the inlet 101 is high and the pressure at the outlet 201 is low, and the pressure difference is greater than the abo...

Example

[0029] Third embodiment:

[0030] see Figure 5 , this example is a valve assembly that is basically the same as the first embodiment, the difference is that the valve body 300 is made of a magnetic body, and the valve cover 100 is made of a magnetic conductor, or, the valve cover 100 is made of a magnetic body and the valve body 300 is made of a magnetic conductor, and also relies on the magnetic force between the two to keep the valve surface 303 close to the inlet surface 102 and block the fluid passage between the inlet 101 and the outlet 201 . When the valve assembly is connected in series in a fluid channel, the pressure at the inlet 101 is high and the pressure at the outlet 201 is low, and the pressure difference is greater than the above-mentioned repulsive force, the valve body 300 will go down under the action of the pressure difference to open the inlet 101 and the fluid channel between outlet 201.

Abstract

The invention relates to a valve and a cartridge, wherein, the valve comprises a case with a valve chamber; the case has a inlet and a outlet to connect the valve chamber and the outer part; a valve is inside the valve chamber; the valve can block the liquid channel between the inlet and outlet via the magnetic force; when the liquid reverse pressure differential force is bigger than magnetic force besides the valve, the valve will open the liquid channel between the inlet and outlet; the cartridge comprises a ink chamber, a air channel, a ink feeding inlet, and the said valve elements inside the air channel and ink feeding channel. The invention has stable operation and property.

Description

technical field [0001] The invention relates to a valve assembly and an ink cartridge used in an inkjet printing device with the structure of the valve assembly. Background technique [0002] Inkjet printing equipment such as desktop inkjet printers, wide-line inkjet printers, etc. all use ink cartridges as ink supply sources. Ink cartridges are usually a container containing ink, and the container is provided with an ink supply port that outputs ink to inkjet printing equipment. , There is also a vent, when the inkjet printing equipment sucks ink from the ink supply port, the ink in the container flows out of the ink supply port, and the air enters the container from the vent to maintain the pressure in the container. In order to prevent the ink from flowing out from the ink supply port under non-use conditions, a certain negative pressure must be maintained inside the container relative to the outside of the container. The previous solution was to place porous fiber materi...
