The scope of embodiments of the invention encompasses the full ambit of the claims, as well as all available equivalents of the claims. In this context, these embodiments of the invention may be referred to, individually or collectively, by the term "utility model" merely for convenience and without automatically limiting the scope of this application to any single utility model or utility model concept if more than one is in fact disclosed.

It should be noted that, in the present invention, the technical features may be combined with each other without conflict.

The embodiment of the utility model discloses a filtering device, as shown in fig. 1-3, fig. 1 is a structural example one of the filtering device in the embodiment of the utility model; fig. 2 is a second structural example of a filtering device in an embodiment of the present invention; fig. 3 is a third structural example of a filtering device in an embodiment of the present invention; the filtering device comprises: a first valve body 1, a second valve body 2 and a filter screen 3. Wherein the first valve body 1 has a first port 101, a second port 102 and a third port 103; the second valve body 2 has a fourth port 201, a fifth port 202 and a sixth port 203; the filter screen 3 is arranged at the first valve port 101 of the first valve body 1, and the first valve port 101 is used as a feeding hole of the filter device; the second valve port 102 of the first valve body 1 is used as a first discharge port of the filtering device; the third port 103 of the first valve body 1 is communicated with the fourth port 201 of the second valve body 2; the fifth valve port 202 of the second valve body 2 is used as a negative pressure port of the filter device; the sixth port 203 of the second valve body 2 is used as a second discharge hole of the filter device; wherein, the first port 101 of the first valve body 1 intersects with the central line of the third port 103, and the fourth port 201 and the fifth port 202 of the second valve body 2 intersect with each other. Wherein the arrow direction indicates the negative pressure direction.

The center line between the valve ports in the embodiment of the present invention intersects with each other to mean that two valve ports are not communicated linearly, for example, the air flow entering from the first valve port 101 needs to be diverted to a certain extent to enter the third valve port 103. The same effect applies to the ink to be filtered.

Before the filter device in this embodiment is used, the negative pressure port (i.e., the fifth valve port 202) of the filter device is first connected to the negative pressure pump through a pipeline, then the ink to be filtered is collected outside the inlet (i.e., the first valve port 101), and after the assembly is completed, the negative pressure pump is activated to penetrate the ink collected outside the inlet into the filter device (i.e., the first valve body 1 and the second valve body 2) through the filter screen, so that the ink passing through the filter screen is collected at the first outlet (i.e., the second valve port 102) and the second outlet (i.e., the sixth valve port 203). In the process, because the third valve port 103 and the first valve port 101 have a certain angle, most of the ink passing through the filter screen can be shot on the opposite surface of the first valve port 101, a small amount of ink can enter the third valve port 103 due to the acting force of negative pressure, and a small amount of ink entering the third valve port 103 can be remained in the second valve body 2 due to the direction changing structure in the second valve body 2, so that the filtering of the ink (or the damage to agglomerated particles in the ink) is realized, and the risk that the ink enters the negative pressure pump is reduced.

The embodiment of the utility model provides an in wait to filter printing ink and filter screen's mesh number can be selected according to operating personnel's actual purpose, and this application does not prescribe a limit to this.

The negative pressure value provided by the negative pressure pump in the embodiment of the utility model is related to whether the printing ink can pass through the filter screen, and the larger the negative pressure is, the higher the efficiency of the filtering device is; conversely, the lower the negative pressure, the lower the efficiency of the filter device. On the other hand, although a higher negative pressure may improve the efficiency of the filter device, it may also increase the risk of ink entering the negative pressure pump, for which the applicant has found that this risk may be reduced by continuing to increase the valve body redirection structure in the present application. For example: for example, one or more third valve bodies which are sequentially communicated are continuously added on the fifth valve port 202 of the second valve body 2, and the negative pressure port is set on the last third valve body, so that the number of direction-changing structures between the feed port and the negative pressure port is increased to adapt to the increased negative pressure effect; for example, one or more sequentially connected fourth valve bodies may be additionally added between the third valve port 103 of the first valve body 1 and the fourth valve port 201 of the second valve body 2, and the number of direction changing structures between the feed port and the negative pressure port may also be increased to achieve similar effects.

The number of the third valve body and/or the fourth valve body in the embodiment can be set or selected according to the actual test effect of an operator, and the application does not limit the number.

In this embodiment, the inlet (i.e., the first valve port 101) and the first outlet (i.e., the second valve port 13) are disposed to be vertically opposite to each other, so that the ink can be concentrated at the first outlet to the greatest extent under the action of the negative pressure in cooperation with the gravity of the ink itself, and the ink that can enter the third valve port 103 is greatly reduced due to the 90 ° direction change angle between the third valve port 103 and the first valve port 101, which are horizontally disposed.

Preferably, for the second valve body 2, the fourth port 201 is located in the middle of the second valve body 2, the fifth port 202 is located at the top of the second valve body 2, and the sixth port 203 is located at the bottom of the second valve body 2; the fourth port 201 of the second valve body 2 is a horizontal structure, and the fifth port 202 and the sixth port 203 are vertically opposite. In this embodiment, the negative pressure port (i.e., the fifth valve port 202) is vertically arranged at the top of the second valve body 2, and the fourth valve port 201 is arranged in a horizontal structure, so that a direction change angle of 90 ° is formed between the fourth valve port 201 and the fifth valve port 202, thereby further reducing the possibility that ink enters the negative pressure port; meanwhile, by matching with the gravity of the ink, the ink is not easy to deflect upwards when being shot from the fourth valve port 201, and meanwhile, the ink is guided to the second discharge port (i.e., the sixth valve port 203).
