The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
For example, a liquid crystal dripper, comprising: a connection part and a drip irrigation part; the connecting part and the drip irrigation part are integrally connected, a drip irrigation channel is formed in the drip irrigation part, and the inside of the connecting part is communicated with the drip irrigation channel; drip irrigation the passageway including first subchannel, second subchannel and the third subchannel that communicates in proper order, first subchannel with the inside intercommunication of connecting portion, the width of third subchannel is greater than the width of first subchannel, the width of second subchannel is by being close to the one end of first subchannel is to being close to the one end gradual increase of third subchannel.
In the above embodiment, the width setting through the terminal third subchannel of will driping irrigation the passageway is great for liquid crystal can effectively gather before the liquid crystal dripper drips out, makes liquid crystal can completely drip to the base plate on, has avoided the condition that liquid crystal drips trace, liquid crystal are trailing, makes the effect of driping irrigation of liquid crystal better, effectively improves the product yield of LCD screen.
In one embodiment, as shown in fig. 1, a liquid crystal dripper 10 is provided, comprising: a connection part 200 and a drip irrigation part 100; the connection part 200 and the drip irrigation part 100 are integrally connected, a drip irrigation channel 110 is formed inside the drip irrigation part 100, and the inside of the connection part 200 is communicated with the drip irrigation channel 110; the drip irrigation channel 110 comprises a first sub-channel 111, a second sub-channel 112 and a third sub-channel 113 which are sequentially communicated, the first sub-channel 111 is communicated with the inside of the connecting part 200, the width of the third sub-channel 113 is greater than that of the first sub-channel 111, and the width of the second sub-channel 112 is gradually increased from one end close to the first sub-channel 111 to one end close to the third sub-channel 113.
Specifically, the connection portion 200 is used for connecting a delivery pipe, the interior of the connection portion 200 is opened with a drip irrigation cavity 201, the drip irrigation cavity 201 is used for communicating with the interior of the delivery pipe, and the drip irrigation cavity is communicated with the first sub-channel 111 of the drip irrigation channel 110. The width of the first sub-channel 111 is smaller than that of the third sub-channel 113, the width of the end of the second sub-channel 112 close to the first sub-channel 111 is equal to that of the first sub-channel 111, and the width of the end of the second sub-channel 112 close to the third sub-channel 113 is equal to that of the third sub-channel 113. In this way, the side wall of the drip irrigation channel 110 is more smoothly transited from the first sub-channel 111 to the second sub-channel 112 and the third sub-channel 113 gradually, which facilitates smooth flow of the liquid crystal.
For example, the first sub-channel 111 has a circular cross section, for example, the second sub-channel 112 has a circular cross section, for example, the third sub-channel 113 has a circular cross section, for example, the cross section of the first sub-channel 111 is circular, for example, the cross section of the second sub-channel 112 is circular, for example, the cross section of the third sub-channel 113 is circular, specifically, in this embodiment, the first sub-channel 111 and the third sub-channel 113 are respectively cylindrical channels, for example, the diameter of the third sub-channel 113 is larger than that of the first sub-channel 111, and the diameter of the second sub-channel 112 gradually increases from one end near the first sub-channel 111 to one end near the third sub-channel 113.
For example, the drip irrigation part 100 has a truncated cone-shaped structure, and specifically, the width of the drip irrigation part 100 gradually decreases from the end close to the connection part 200 to the end away from the connection part 200, so that the width of the end of the drip irrigation part 100 away from the connection part 200 is decreased to be equal to the width of the third sub-channel 113, which is beneficial to accurately aligning the drip irrigation part 100 with the position on the substrate where the liquid crystal needs to be dripped, and effectively improving the drip irrigation accuracy.
For convenience of illustration, in each embodiment, an end of the drip irrigation channel 110 near the first sub-channel 111 is defined as a beginning end, and an end of the drip irrigation channel 110 near the third sub-channel 113 is defined as an end, depending on the flow direction of the liquid crystal. According to the flow formula Q of the fluid, wherein Q is the flow rate of the fluid, V is the flow velocity of the fluid, and a is the area of the cross section of the fluid channel, and when the flow rate is stable, the larger the area a of the cross section of the fluid channel is, the smaller the flow velocity V of the fluid is, so that the width of the third sub-channel 113 at the end of the drip irrigation channel 110 is larger, and the area of the cross section of the third sub-channel 113 is larger, so that the flow velocity of the liquid crystal in the third sub-channel 113 is smaller, and the liquid crystal is fully gathered in the third sub-channel 113 before the drip irrigation part 100 completely drips, so that the liquid crystal can be fully gathered in the third sub-channel 113, and further the liquid crystal can be completely dripped onto the substrate, thereby avoiding the situations of liquid crystal dripping marks and liquid crystal tailing, so that the dripping effect of the liquid crystal is better, and the product yield of the liquid crystal screen is effectively improved.
In order to make the liquid crystal drop on the substrate efficiently and avoid the liquid crystal from adhering to the liquid crystal dripper 10 after dropping from the third sub-channel 113, in one embodiment, referring to fig. 1 again, an arc-shaped portion 120 is disposed at one end of the drip irrigation part 100 away from the connecting part 200, and the arc-shaped portion 120 is disposed around the outside of the third sub-channel 113. For example, the arc-shaped portion 120 has an arc-shaped cross section, for example, the cross section of the outer side surface of the arc-shaped portion 120 on a plane parallel to the axial direction of the third sub-channel 113 is arc-shaped, for example, the cross section of the outer side surface of the arc-shaped portion 120 on a plane parallel to the axial direction of the drip irrigation part 100 is arc-shaped, for example, the arc-shaped portion 120 is gradually curved from one end away from the connecting part 200 to the direction close to the connecting part 200.
In this embodiment, when the liquid crystal drips from the end of the third sub-channel 113, the arc-shaped portion 120 can effectively prevent the liquid crystal from staying on the outer surface of the end of the liquid crystal dripper 10, so that the liquid crystal can drip onto the substrate efficiently, and the dripping effect of the liquid crystal is better.
To further enable the liquid crystal to smoothly flow from the first sub-channel 111 to the third sub-channel 113, in one embodiment, referring again to fig. 1, the second sub-channel 112 has an arc-shaped cross-section. For example, the sidewall 115 of the second sub-channel 112 has an arc-shaped cross section, for example, the cross section of the sidewall 115 of the second sub-channel 112 in a plane parallel to the axial direction of the third sub-channel 113 is arc-shaped, for example, the cross section of the sidewall 115 of the second sub-channel 112 in a plane parallel to the axial direction of the drip irrigation part 100 is arc-shaped, for example, the sidewall 115 of the second sub-channel 112 is gradually curved inward from one end near the first sub-channel 111 to one end near the third sub-channel 113.
In this embodiment, the first sub-passage 111 communicates with the third sub-passage 113 through the arc-shaped second sub-passage 112, in this way, the liquid crystal in the first sub-channel 111 will flow from the second sub-channel 112 to the third sub-channel 113, and the sidewall of the second sub-channel 112 is arc-shaped, so that the liquid crystal can flow more smoothly along the sidewall of the second sub-channel 112, thereby enabling the liquid crystal to smoothly and smoothly flow from the first sub-channel 111 to the third sub-channel 113 along the second sub-channel 112, so that the flow of the liquid crystal in the drip irrigation channel 110 is smoother, and because the length of the arc is longer than that of the straight line, the flow speed of the liquid crystal can be further slowed down, and then make the liquid crystal can assemble completely in third subchannel 113 for the liquid crystal can be on the whole drippage to the base plate, has avoided the trailing condition of liquid crystal, makes the drippage effect of liquid crystal better, effectively improves the product yield of LCD screen.
In order to further improve the smoothness of the flow of the liquid crystal in the second sub-channel 112, for example, the radian of the sidewall of the second sub-channel 112 is 5rad to 10rad, it is worth mentioning that the smaller the radian of the sidewall of the second sub-channel 112 is, the smoother the sidewall of the second sub-channel 112 is, which is beneficial to improving the smooth shape of the flow of the liquid crystal, however, the smaller the radian is, the sidewall of the second sub-channel tends to be flat, which results in the liquid crystal not being easily gathered, in this embodiment, the radian of the sidewall of the second sub-channel 112 is 5rad to 10rad, which can further improve the smoothness of the flow of the liquid crystal in the second sub-channel 112 and improve the gathering efficiency of the liquid crystal to the third sub-channel.
In order to improve the drip irrigation efficiency and make the drip irrigation effect more effective, in one embodiment, the width of the first sub-channel 111 is 0.3 mm. For example, the width of the third sub-channel 113 is 0.5 mm.
It should be noted that there are two general diameters of the inner channel of the conventional liquid crystal dripper 10, which are 0.3mm or 0.5mm respectively. The dripping speed of the 0.3mm dripper is too high due to the small diameter, so that accumulated dripping or splashing of liquid crystal is easily caused, and the situation that the liquid crystal does not completely drip when the dripper moves can also be caused; the 0.5mm water dropper has slow drip irrigation speed under the condition of stable flow of liquid crystal, so that the production efficiency is low; the control precision of the liquid crystal amount of other sizes is lower, so the diameter of the traditional liquid crystal dripper cannot meet the requirement of accurate drip irrigation. In this embodiment, the width of the first sub-channel 111 is 0.3mm, the width of the third sub-channel 113 is 0.5mm, so that the diameter of the initial section of the drip irrigation channel 110 is 0.3mm, the diameter of the tail end is 0.5mm, the diameter of the initial section is 0.3mm, the diameter of the tail end is smaller, which is beneficial to improving the flowing speed of the liquid crystal, and the diameter of the tail end is 0.5mm, which is larger, which is beneficial to converging the liquid crystal, so that the complete liquid crystal can be converged and then dripped onto the substrate, that is, the liquid crystal can flow more smoothly, and the liquid crystal can be completely dripped, thereby avoiding the situation of liquid crystal trailing, ensuring that the dripping effect of the liquid crystal is better, and effectively improving the product yield of the liquid crystal display.
In this embodiment, the width of the first sub-channel 111 is 0.3mm, the width of the third sub-channel 113 is 0.5mm, and the side wall of the second sub-channel 112 is provided with an arc shape, so that the flow velocity of the liquid crystal in the drip irrigation channel 110 can be reduced by 2.77 times, the dropping speed of the liquid crystal is effectively controlled, the dropping speed of the liquid crystal is reduced, the instantaneous speed of the liquid crystal dropping from the tail end of the drip irrigation channel 110 is further effectively reduced, and the adverse phenomena of liquid crystal dropping marks and liquid crystal tailing of the liquid crystal panel in the manufacturing process are improved.

The connecting part 200 is connected with the delivery pipe through threads, so that the liquid crystal dripper 10 is more convenient and quicker to mount, connect and dismount with the delivery pipe.
In one embodiment, a liquid crystal drip irrigation device 20 is provided, comprising the liquid crystal dripper 10 described in any of the above embodiments.
In one embodiment, as shown in fig. 2, the liquid crystal drip irrigation device 20 further comprises a liquid crystal container 300 and a delivery pipe 400, wherein the liquid crystal container 300 is connected with the liquid crystal dripper 10 through the delivery pipe 400, and the delivery pipe 400 is provided with a steering pump valve 410.
