Embodiment

[0018] A low-water-level livestock and poultry waterer, combined with Figure 1 and Figure 2 as shown, includes a housing 1, a detachable inner cover 2, a sealing assembly 3, a valve stem 4, and a base 5.

[0019] The housing 1 includes a connecting portion 11, an external thread on the connecting portion 111, and internal thread or protrusion or depression 12 on the inner wall of the housing; the detachable inner cover 2 includes an external thread or depression or protrusion 21 on the inner cover, an inner hole 22 of the inner cover, the sealing assembly 3 includes a flow-limiting unit 31 and a sealing unit 32; the valve stem 4 includes a valve stem sealing unit 41 and a triggering unit 42; the valve stem 5 includes an upper sealing unit 51 on the base and a lower sealing unit 52 on the base.

[0020] I. The upper part of the housing 1 is a connecting portion 11 connected to a water pipe. The connecting portion 11 can be fixedly connected to the water pipe through the external thread 111 on the connecting portion. The interior of the livestock and poultry waterer has a vertically through structure, so that the liquid in the water pipe can flow out from top to bottom through the housing 1 for livestock and poultry to drink.

[0021] II. A detachable inner cover 2 is provided inside the livestock and poultry waterer. The detachable inner cover 2 can be installed in the livestock and poultry waterer and fixed inside the livestock and poultry waterer, and the detachable inner cover 2 can also be taken out from the livestock and poultry waterer. After taking out the detachable inner cover 2, other components of the waterer such as the sealing assembly 3, the valve stem 4, the base 5, etc. can be installed inside the livestock and poultry. After covering the detachable inner cover 2, other components inside the livestock and poultry waterer will not fall outside the livestock and poultry waterer during use. Thanks to the setting of the detachable inner cover 2, the assembly and disassembly of the waterer become very convenient, and the connecting portion 11 between the housing 1 of this low-water-level livestock and poultry waterer and the water pipe can be set very short, and the upper edge of the connecting portion 11 can be flush with the inner wall of the water pipe or even lower than the inner wall of the water pipe. The detachable inner cover 2 also serves as a slide rail for the sealing assembly 3 to prevent the sealing assembly from shifting during movement.

[0022] III. There are internal thread ports, protrusions or depressions 12 on the inner wall of the housing 1. The outer wall of the detachable inner cover 2 is provided with outer thread ports, depressions or protrusions 21 on the outer side of the inner cover, which form an engagement with the thread ports, protrusions or depressions 12 on the inner wall of the housing 1, so as to facilitate the removal or installation of the detachable inner cover 2 into the livestock and poultry waterer.

[0023] IV. The detachable inner cover 2 is provided with an inner hole 22 that penetrates up and down. The inner hole 22 of the inner cover is preferably a cylindrical hole, and the liquid entering the connecting part 11 of the housing can enter the livestock and poultry waterer through the inner hole 22 of the inner cover.

[0024] V. The sealing assembly 3 is composed of two cylindrical structures. The upper part is a flow-limiting unit 31, and the lower part is a sealing unit 32. The diameter of the flow-limiting unit 31 is slightly smaller than the diameter of the inner hole 22 of the inner cover. The flow-limiting unit 31 is sleeved into the inner hole 22 of the inner cover and can move up and down. Since the gap between the flow-limiting unit 31 and the inner hole 22 of the inner cover is small, it can play a role in restricting the liquid flow into the livestock and poultry waterer. The sealing unit 32 is preferably cylindrical. When the sealing unit 3 is stationary, the bottom can fit with the sealing unit 51 on the base, so as to achieve the purpose of sealing. When the sealing unit 3 moves, a gap is generated between the sealing unit 32 and the diameter of the sealing unit on the base, and the liquid inside the livestock and poultry waterer can flow downward through this gap. The inner hole 22 of the inner cover also serves as a guide rail for the flow-limiting unit 31 to prevent the sealing assembly 3 from shifting during movement and affecting the sealing effect.

[0025] VI. The valve stem 4 is composed of a valve stem sealing unit 41 and a trigger unit 42. The valve stem sealing unit 41 is preferably a cylindrical structure. When the valve stem 4 is stationary, the lower edge of the valve stem sealing unit 41 can fit with the lower sealing unit 52 on the base to form a sealed structure. When the trigger unit 42 is touched by livestock and poultry, a gap is generated between the sealing unit 41 and the lower sealing unit 52 on the base, and the liquid inside the livestock and poultry waterer can flow downward through this gap for livestock and poultry to drink.

[0026] VII. When the trigger unit 42 is touched by livestock and poultry, the valve stem sealing unit 41 will push the sealing assembly 3 upward.

[0027] VIII. The inner hole 22 inside the detachable inner cover 2 can also be polygonal or of other shapes, and the flow-limiting unit 31 of the sealing assembly 3 can also be a corresponding polygon or of other shapes.

[0028] IX. The bottom of the sealing unit 32 of the sealing assembly 3 can also be spherical segment-shaped or frustum-shaped.

[0029] X. The inner hole 22 of the inner cover can also be a mesh structure or strip-shaped, annular or of other shapes.

[0030] XI. The base 5 is installed at the lower part of the housing 1, and the base 5 can also be an integral part with the housing 1.

[0031] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it based on the present invention, which will be obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
