Description

Technical Field

[0001] This utility model relates to the field of animal husbandry and feeding, and in particular to a simple animal drinking water device. Background Technology

[0002] Livestock waterers are designed to match modern livestock farming techniques and provide animals with clean drinking water. Currently, livestock waterers have a relatively complex structure.

[0003] Chinese Patent Publication No. CN207927506U, published on October 2, 2018, discloses a pig waterer. In this patent, the internal channel of the outer shell requires machining two threaded sections (at the inlet and outlet), and bolts are installed at the corresponding threaded sections. The shell also contains a tapered section adapted to the valve core. The pig waterer mentioned in this application is difficult to manufacture, has many assembly parts, resulting in high production costs and making it difficult to promote. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of complex shell structures and numerous assembly parts in existing livestock waterers, which lead to high production difficulties and limited adoption. This invention provides a livestock waterer with a simpler structure, simplifying the processing of the outer shell and reducing the number of assembly parts.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A simple livestock watering device includes:

[0007] The outer casing has a through channel for water supply inside. The inner sidewall of the through channel is provided with an annular groove and an annular protrusion along its circumference, and the annular groove and annular protrusion are spaced apart.

[0008] The switching structure includes an elastic element, a valve core, and a valve stem structure arranged sequentially along the water flow direction. One end of the elastic element is engaged in the annular groove, and the other end of the elastic element abuts against the valve core. The valve core is constrained between the elastic element and the annular boss. The valve core has a sealed state that blocks the through channel and an open state that opens the through channel. The valve stem structure is used to pry the valve core from the sealed state to the open state.

[0009] In this design, the elastic force of the elastic element keeps the valve core in a sealed state. When an animal bites the valve stem, the valve stem deflects, and the valve core is pried from the sealed state to the open state, allowing water to flow through the valve core. By setting an annular groove to fix one end of the spring, the number of parts used to seal the spring is reduced and the threaded section of the part does not need to be machined, simplifying the processing and manufacturing of the housing. In addition, the installation of the spring is simplified, improving the assembly efficiency of the livestock waterer.

[0010] Preferably, the through channel includes a water inlet section, an elastic element section, a valve core section, and a valve stem section. The annular groove is located between the water inlet section and the elastic element section, and the annular boss is located between the valve core section and the valve stem section. The elastic element is installed in the elastic section, the valve core is installed in the valve core section, and part of the valve stem is located in the valve stem section.

[0011] Preferably, the valve core includes a sealing portion and a drain portion. The sealing portion is provided with a locking head and a sealing ring, and the drain portion has a drain groove for water flow. The diameter of the locking head is smaller than the diameter of the valve core section, and the diameter of the locking head is larger than the diameter of the through hole on the annular boss. The diameter of the drain portion is smaller than the diameter of the through hole on the annular boss. When the valve core is in a sealed state, the sealing ring of the sealing portion presses against the annular boss to seal the through channel. When the valve stem pries the valve core, the valve core deflects. At this time, part of the sealing ring on the sealing portion disengages from the valve core section, forming a gap. Water flows through the gap, bypassing the sealing portion, and then flows through the drain portion.

[0012] Preferably, the valve stem structure includes a valve stem and a locking nut. The valve stem includes a rod body and a top plate disposed at the end of the rod body. The valve stem has a water outlet channel communicating with the through channel. The water outlet channel passes through the rod body and the top plate. The axis of the water outlet channel is collinear with the axis of the rod body. The locking nut is used to restrict the top plate below the valve core. The locking nut has an external thread section. The outlet of the through channel is provided with an internal thread section adapted to the external thread section. The locking nut has a through hole. The rod body passes through the through hole and exits the through channel. The diameter of the through hole is larger than the diameter of the rod body and smaller than the diameter of the top plate.

[0013] Preferably, the top plate and the valve core are spaced apart. The gap between the top plate and the valve core allows for movement of the top plate, facilitating the prying of the valve core.

[0014] Preferably, the diameter of the through hole gradually increases along the water flow direction. The diameter of the through hole gradually increases, with a smaller diameter near the valve core to facilitate stabilizing the valve stem; the larger diameter near the valve core provides more room for the valve stem to swing.

[0015] Preferably, the elastic element includes a connected mounting portion and a rebound portion. The mounting portion is a support ring for engaging with an annular groove, and the rebound portion is a conical spring for providing elastic force. The conical spring has a large-diameter end and a small-diameter end, with the support ring located at the large-diameter end and the small-diameter end abutting against the valve core. The conical spring has a compact structure, is easy to install, and has a long service life.

[0016] Preferably, the elastic element includes a connected mounting portion and a return portion. The mounting portion is a mounting ring for engaging with an annular groove, and the return portion is a straight spring for providing elastic force. Straight springs have a simple structure and are inexpensive.

[0017] Preferably, the annular groove is provided with a retaining ring for securing the elastic element.

[0018] Preferably, the housing is provided with a threaded section for connecting to an external water supply mechanism. Connecting to the external water supply mechanism via the threaded section ensures convenient installation and a secure connection.

[0019] The principle and beneficial effects of this utility model that adopts the above technical solution are as follows:

[0020] 1. The internal thread section at the water inlet of the through channel does not require machining, simplifying the shell production process.

[0021] 2. The elastic element is fixed by an annular groove inside the through-channel, reducing the number of components for fixing the spring. Attached Figure Description

[0035] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0037] The specific implementation of this utility model is as follows:

[0038] like Figures 1 to 10As shown, this utility model provides a simple livestock waterer 100, including a shell 10 and a switch structure. The shell 10 has a through channel 11 for water flow inside. The inner side wall of the through channel 11 is provided with an annular groove 17 and an annular boss 12 along its circumference. The annular groove 17 and the annular boss 12 are spaced apart. The switch structure includes an elastic element 40, a valve core 20 and a valve stem 30 structure arranged sequentially along the water flow direction. One end of the elastic element 40 is stuck in the annular groove 17, and the other end of the elastic element 40 abuts against the valve core 20. The elastic element 40 is compressed between the annular groove 17 and the valve core 20. The valve core 20 is restricted between the elastic element 40 and the annular boss 12. The valve core 20 has a sealed state that blocks the through channel 11 and an open state that opens the through channel 11. The valve stem 30 structure is used to pry the valve core 20 to switch from the sealed state to the open state. Understandably, under the elastic force of the elastic element 40, the valve core 20 is pressed against the annular boss 12 and the through hole 121 on the annular boss 12 is blocked, at which time the valve core 20 is in a sealed state; when the valve stem structure pries the valve core 20 to the open state, the valve core 20 deflects on the annular boss 12, at which time a gap is formed between the valve core 20 and the annular boss 12, and water flows out from the gap; when the valve stem structure no longer pries the valve core 20, the elastic force of the elastic element 40 drives the valve core 20 to return to the sealed state.

[0039] like Figures 3 to 10As shown, the through channel 11 includes a water inlet section 13, an elastic element section 14, a valve core section 15, and a valve stem section 16. An annular groove 17 is located between the water inlet section 13 and the elastic element section 14, and an annular boss 12 is located between the valve core section 15 and the valve stem section 16. The elastic element 40 is installed in the elastic section, the valve core 20 is installed in the valve core section 15, and part of the valve stem 30 is located in the valve stem section 16. The elastic force of the elastic element 40 keeps the valve core 20 in a sealed state. When an animal bites the valve stem 30, it will cause the valve stem 30 to deflect. At this time, the valve core 20 is pried from the sealed state to the open state, allowing water to flow through the valve core 20. By setting the annular groove 17 to fix one end of the spring, the number of parts used to seal the spring is reduced and the threaded part of the part does not need to be machined, simplifying the processing and manufacturing of the housing. In addition, the installation of the spring is simplified, improving the assembly efficiency of the livestock waterer 100. The elastic element 40 includes a mounting part and a return part. In this embodiment, the mounting part is a support ring 42 for engaging with the annular groove, and the return part is a conical spring 41. The conical spring 41 has a large-diameter end and a small-diameter end. The support ring 42 is located at the large-diameter end and is adapted to the annular groove 17, while the small-diameter end abuts against the valve core. The conical spring 41 has a compact structure, is easy to install, and has a long service life. It should be noted that the support ring 42 has two shapes: a layered shape and a coiled shape. In actual use, whether to install the retaining ring 171 depends on the shape of the support ring 42. When the support ring 42 is layered, its own stability is not high, and installing the retaining ring 171 in the annular groove 17 can greatly improve the stability of the elastic element, so the retaining ring 171 needs to be installed. When the support ring 42 is coiled, its own stability is high, and the retaining ring 171 does not need to be installed in the annular groove 17. There is no restriction on the installation of the retaining ring 171; it can be selected according to actual needs.

[0040] like Figure 5 and Figure 6As shown, the valve core 20 includes a sealing part 21 and a draining part 22. The sealing part 21 is provided with a clamp 211 and a sealing ring 212. The draining part 22 has a draining groove 221 for water flow. The diameter of the clamp 211 is smaller than the diameter of the valve core section 15, and the diameter of the clamp 211 is larger than the diameter of the through hole 121 on the annular boss 12. The diameter of the draining part 22 is smaller than the diameter of the through hole 121 on the annular boss 12. In this embodiment, the cross-sections of both the sealing part 21 and the draining part 22 are circular, and the draining groove 221 is a cross groove provided in the draining part 22. When the valve core 20 is in a sealed state, the sealing ring 212 of the sealing part 21 fits tightly with the annular boss 12, thereby sealing the through hole 121 on the annular boss; when the valve stem 30 pries the valve core 20, the valve core 20 deflects, at which time part of the sealing ring on the sealing part 21 disengages from the annular boss 12, and a gap appears between the sealing part 21 and the annular boss 12. The water flows through the gap, bypasses the sealing part 21, and flows through the discharge part 22. It should be noted that the diameter of the clamp 211 is smaller than the diameter of the valve core section 15, and the diameter of the clamp 211 is larger than the diameter of the through hole 121 on the annular boss 12, so that the valve core 20 can be installed into the valve core section 15 and restricted at the annular boss 12 by the clamp 211; the diameter of the discharge part 22 is smaller than the diameter of the through hole 121 on the annular boss 12, the discharge part 22 is located below the annular boss 12, and there is a gap between the discharge part 22 and the through hole 121, which ensures the flow rate of water when the valve core 20 is in the open state.

[0041] like Figure 8 As shown, the valve stem 30 structure includes a valve stem 30 and a locking nut 31. The valve stem 30 includes a rod body 301 and a top plate 302 disposed at the end of the rod body 301. The top plate 302 is spaced apart from the valve core 20. The valve stem 30 has a water outlet channel 303 connected to the through channel 11. The water outlet channel 303 passes through the rod body 301 and the top plate 302. The axis of the water outlet channel 303 is on the same straight line as the axis of the rod body 301. The locking nut 31 is used to restrict the top plate 302 below the valve core 20. The locking nut 31 has an external thread section 312. The outlet of the through channel 11 is provided with an internal thread section 18 that matches the external thread section. The locking nut 31 has a through hole 311. The rod body 301 passes through the through hole 311 and exits the through channel 11. The diameter of the through hole 311 is larger than the diameter of the rod body 301 and smaller than the diameter of the top plate 302. When an animal drinks, it bites the exposed rod 301 in the through-channel 11 and shakes it. The rod 301 pries the valve core 20 from a sealed state to an open state, and the water flows around the valve core 20 and into the water outlet channel 303 of the valve rod 30. When the animal stops biting the valve rod 30, the elastic force of the elastic element 40 drives the valve core 20 from an open state to a sealed state, at which point the livestock waterer 100 stops dispensing water. In this embodiment, there is a gap between the top plate 302 and the valve core 20 to allow the top plate 302 room to move and facilitate the prying of the valve core 20.

[0042] like Figure 8 As shown, the diameter of the through hole 311 gradually increases along the water flow direction. The diameter of the through hole 311 gradually widens, with a smaller diameter near the valve core 20 to facilitate stabilizing the valve stem 30; the larger diameter near the valve core 20 provides more space for the valve stem 30 to swing. In actual operation, the water output increases with the increase in the angle at which the valve stem 30 swings as the animal grows.

[0043] like Figure 1 As shown, the outer casing 10 is provided with a threaded section 19 for connecting to an external water supply mechanism. The water supply pipe of the external water supply mechanism is connected via the threaded section 19, making installation convenient and the connection secure. It should be noted that the animals mentioned in this application refer to livestock animals with a certain biting force, such as pigs, cattle, and sheep. In actual installation, an appropriate installation height should be selected based on the type of animal being raised.

[0044] Example 2:

[0045] like Figure 11 As shown, the difference between this embodiment and Embodiment 1 is that the elastic element 40 includes a mounting part and a rebound part; the rebound part is a straight spring 43, and the mounting part is a mounting ring 44 connected to one end of the straight spring; during installation, the mounting ring 44 is inserted into the annular groove 17, and the other end of the straight spring 43 abuts against the valve core 20. The straight spring 43 has a simple structure and low cost, further reducing the cost of the livestock waterer 100. It is understood that the mounting ring 44 also has two shapes: a layered shape and a coiled shape. Whether to install the retaining ring depends on the actual situation, which will not be elaborated here.

[0046] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
