Description

Technical Field

[0001] The utility model belongs to the technical field of pig farm drinking water systems, in particular to a drinking water nozzle for pigs. Background Art

[0002] Pig drinking spouts are indispensable livestock accessories for pig farms, including duckbill drinking spouts, nipple drinking spouts, and cup drinking spouts. In the prior art, a typical duckbill drinking spout is a livestock drinking spout disclosed in document CN201374953Y, which consists of a pressure rod (valve stem), a valve body, a rubber ring, a spring, and a spring plug, and a spiral convex and concave pattern is processed on the surface of the pressure rod.

[0003] When using a duckbill drinking spout, the pig holds the drinker in its mouth and bites the valve stem, water flows out from the gap between the valve core and the sealing ring and enters the pig's mouth. When the mouth is loosened, the valve stem is driven to reset by the tension of the return spring, the water outlet gap is closed, and the water stops flowing out. However, the duckbill drinking spout has the following problems during use: the water flowing out of the duckbill drinking spout is usually in the form of a jet, which can easily cause the pig to choke, making the pig less comfortable during the drinking process.

DETAILED DESCRIPTION

[0019] The following is a clear and complete description of the technical solution of the utility model in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1: Please refer to Figure 1-2 A drinking nozzle for pigs includes a shell 1. The right side of the shell 1 is connected to a plug cover 2. A filter screen 3 is arranged on the right side of the plug cover 2. A connecting pipe 5 is opened on the left surface of the plug cover 2. A threaded groove is arranged on the inner wall of one side of the shell 1. One side of the plug cover 2 is threadably connected to the threaded groove through the connecting pipe 5.

[0021] according to Figure 2 A return spring 6 is abutted on the left side of the plug cover 2, a through hole is opened on the inner wall of the connecting pipe 5, one end of the return spring 6 is located on the inner wall of the through hole, the other end of the return spring 6 is sleeved on the outer wall of one side of the core rod 4, the other side of the return spring 6 abuts against the core rod 4, a baffle ring 14 is provided on the inner wall of the shell 1, and a fixing ring is sleeved on the outer wall of the core rod 4, and the diameter of the fixing ring is larger than the inner diameter of the baffle ring 14.

[0022] according to Figure 2-3 A mounting groove 7 is provided on the surface of the core rod 4, and a rubber ring 8 is sleeved inside the mounting groove 7. A first buffer plate 9 is sleeved on one side of the outer wall of the rubber ring 8, and a second buffer plate 10 is sleeved on the other side of the outer wall of the rubber ring 8. The first buffer plate 9 and the second buffer plate 10 are spliced ​​half and half on the outside of the rubber ring 8, and the first buffer plate 9 and the second buffer plate 10 are inclined to the left from top to bottom. A buffer strip 11 is laid on one side surface of the first buffer plate 9, and a first guide plate 12 and a second guide plate 13 are respectively provided on the upper and lower sides of the inner wall of the shell 1. The first guide plate 12 and the second guide plate 13 are both inclined to the left, and the vertical line where the second guide plate 13 is located is located on the left side of the vertical line where the first guide plate 12 is located. The first guide plate 12 and the second guide plate 13 are respectively located on the opposite side of the first buffer plate 9 and the baffle ring 14 and on the opposite side of the second buffer plate 10 and the baffle ring 14.

[0023] When the pig drinks water, the pig bites the core rod 4 with its mouth, which drives the core rod 4 to deflect downward. The fixing ring on the outer wall of the core rod 4 deflects as the core rod 4 deflects, the return spring 6 bends, and a gap is generated between the fixing ring and the baffle ring 14. Most of the water flows through the gap and enters between the first buffer plate 9 and the opposite side of the baffle ring 14, and a small part is directly located between the second buffer plate 10 and the opposite side of the baffle ring 14. At this time, due to the deflection of the core rod 4, the gap between the second buffer plate 10 and the inner wall of the shell 1 becomes smaller, and the gap between the first buffer plate 9 and the inner wall of the shell 1 becomes larger. Most of the water cannot pass through the maximum gap between the first buffer plate 9 and the inner wall of the shell 1 due to air pressure reasons. Therefore, the water flows through the surface of the first buffer plate 9 and one side surface of the second buffer plate 10 to converge between the second buffer plate 10 and the baffle ring 14, and flows out from between the second buffer plate 10 and the inner wall of the shell 1. The cooperation of the first guide plate 12 and the second guide plate 13 can reduce the impact force of the water flow when the water flows from between the baffle ring 14 and the fixed ring to between the first buffer plate 9 and the opposite side of the baffle ring 14. The laying of the buffer strip 11 can also reduce the flow impact force of the water flow, so that the water flow can flow into the second buffer plate 10 and the baffle ring 14 as much as possible. In general, the scheme can well prevent the occurrence of jet flow at the drinking spout through the cooperation of the above-mentioned structures, effectively avoid the occurrence of pigs being choked when drinking water, and ensure the comfort of the pigs during the drinking process.

[0024] Embodiment 2: According to Figure 4 As shown, the main structure refers to Example 1, and the outer wall of the rubber ring 8 is sleeved with a ring 15, and the outer side of the ring 15 is about 2 mm away from the inner wall of the shell 1. The pig bites the core rod 4, which causes the core rod 4 to deflect, and drives the fixed ring to deflect, so the water flows from between the fixed ring and the blocking ring 14 to between the ring 15 and the blocking ring 14, and as the ring 15 is affected by the core rod 4 and flips, the gap between the top of the ring 15 and the shell 1 becomes larger, and the water can be discharged from the outside of the shell 1 through the enlarged water flow, so that the pigs can drink water. In this embodiment, the ring 15 prevents the formation of the jet flow, so that the water flows out from the edge of the ring 15.

[0025] Embodiment 3: The main structure refers to embodiment 1, according to Figure 5 As shown, the outer wall of the rubber ring 8 is provided with a non-full-circumference ring 16 (in essence, a portion of the ring is cut off laterally, such as Figure 6As shown in the figure, the gap between the bottom of the non-full-circumference circular ring 16 and the shell 1 is larger than the gap between the top of the non-full-circumference circular ring 16 and the shell 1, and the bottom of the non-full-circumference circular ring 16 can also block the jetted water flow. When the pig bites the core rod 4, the core rod 4 drives the non-full-circumference circular ring 16 to move downward, and the water flow initially enters from the bottom of the fixed ring and flows into the gap between the top of the non-full-circumference circular ring 16 and the shell 1, and then flows from this gap into the gap between the edge of the non-full-circumference circular ring 16 and the inner wall of the shell 1, and then flows out normally. During the flow of water, it hits the blocking ring 14 and the non-full-circumference circular ring 16 in turn, thereby greatly reducing the impact force of the water flow, preventing the formation of the jet flow through the non-full-circumference circular ring 16, so that the water flow flows out from the edge of the non-full-circumference circular ring 16.
