[0040] like Figure 1-3 A pet drinking fountain is shown, the pet drinking fountain comprises a water storage container 1 and a drinking water pipe 2, the water storage container 1 comprises a kettle 11, a kettle cover 12 and a vent valve 13. A water storage cavity is provided in the kettle 11, and the bottom of the kettle 11 has an opening. The kettle cover 12 is arranged at the bottom of the water storage container 1, specifically, at the opening at the bottom of the kettle 11. The vent valve 13 is arranged in the kettle cover 12, and a vent channel is provided in the vent valve 13, one end of the vent channel is connected to the water storage cavity, and the other end of the vent channel is connected to the external air. The upper end of the drinking water pipe 2 is connected to the kettle cover 12, and the drinking water pipe 2 is connected to the inside of the kettle 11. The end of the drinking water pipe 2 is the lower end, which is used for pets to drink water. In this embodiment, the vent valve 13 is arranged in the kettle cover 12, and the vent valve 13 is provided with a vent channel. The pet drinking fountain is used upside down, that is, the water storage container 1 is installed upside down, and the pet can drink the drinking water flowing out from the end of the drinking water pipe 2 by touching or licking the end of the drinking water pipe 2. As the number of times the pet drinks water increases, the water storage container 1 becomes under negative pressure, and the ventilation valve 13 absorbs external air through the ventilation channel, thereby ensuring the pressure balance inside and outside the water storage container 1, so that the pet can continuously flow out from the drinking water pipe 2 when drinking, avoiding the problem of water shortage or water jam caused by negative pressure inside the water storage container 1.

[0041] In some embodiments of the drinking water pipeline 2, such as Figure 2 , Figure 3As shown, the drinking water pipe 2 includes a water pipe 21 , a kettle spout 22 , a spherical body 23 and an elastic member 24 .

[0042] The water pipe 21 is connected to the kettle cover 12, the kettle spout 22 is connected to the water pipe 21, the spherical body 23 is arranged at the end of the kettle spout 22, the spherical body 23 is exposed from the kettle spout 22, and the elastic member 24 is arranged in the kettle spout 22, the elastic member 24 abuts against the spherical body 23 and applies elastic force to the spherical body 23. After being touched or licked, the spherical body 23 rotates or moves, so that a gap is formed between the spherical body 23 and the kettle spout 22, and drinking water flows out of the gap, so that it can be drunk by the pet. After the pet stops touching or licking, the spherical body 23 is close to the kettle spout 22 due to the water pressure, and at the same time, under the action of the elastic member 24, it has a better sealing effect and leak-proof effect.

[0043] The spherical body 23 can be specifically a spherical structure such as a steel ball or a glass ball.

[0044] In addition, if Figure 2 , Figure 3 As shown, the end of the kettle spout 22 is provided with an annular sealing groove 221. The drinking water pipe 2 also includes a spout sealing ring 25, which is arranged in the sealing groove 221. The spherical body 23 abuts against the spout sealing ring 25. The spout sealing ring 25 can be tightly attached to the spherical body 23, further increasing the sealing and leakproof effect of the spherical body 23 and the kettle spout 22.

[0045] After the vent valve 13 is added, the water storage container 1 is balanced with the external pressure, and the drinking water is acted on the drinking water pipe 2 by gravity, which is generally more likely to cause leakage of the kettle spout 22. In this embodiment, after the spout sealing ring 25 is provided at the kettle spout 22, the sealing and leak-proof effect of the kettle spout 22 can be enhanced, and the leakage problem caused by the addition of the vent valve 13 can be avoided.

[0046] Furthermore, if Figure 3 , Figure 5 As shown, the drinking water pipe 2 also includes a flow limiting plug 26, which is arranged in the drinking water pipe 2 for blocking the drinking water pipe 2. The flow limiting plug 26 is provided with a first flow limiting hole 263 for limiting the flow of drinking water. The specific size of the first flow limiting hole 263 can be 1 to 3 mm in inner diameter, or other holes with similar cross-sectional areas. The first flow limiting hole 263 can limit the flow of drinking water, prevent excessive touching and licking by pets, resulting in excessive flow of drinking water, and avoid or reduce drinking water leakage.

[0047] Furthermore, the water pipe 21 and the kettle spout 22 are threadedly connected. The flow limiting plug 26 includes a sealing ring 261 and a flow limiting cap 262 arranged on the sealing ring 261, the sealing ring 261 is arranged at the threaded connection between the water pipe 21 and the kettle spout 22, and the flow limiting cap 262 is provided with a first flow limiting hole 263. In this embodiment, the sealing ring 261 is arranged in the flow limiting plug 26, and the sealing ring 261 is installed at the threaded connection between the water pipe 21 and the kettle spout 22, so that the flow limiting plug 26 can seal the connection gap between the water pipe 21 and the kettle spout 22 while limiting the flow.

[0048] The sealing ring 261 is arranged at the threaded connection between the water pipe 21 and the kettle spout 22. Specifically, one of the water pipe 21 and the kettle spout 22 has an internal thread, and the other has an external thread. The inner end of the internal thread of the one with the internal thread is also provided with an annular groove, and the sealing ring 261 is arranged in the annular groove.

[0049] In some embodiments of the ventilation channel, the ventilation channel includes a buffer cavity 133 and an inner air channel 134. The buffer cavity 133 is connected to the inner air channel 134 for temporarily storing overflowed drinking water, and the inner air channel 134 is connected to the water storage cavity. A second flow limiting hole 121 is provided at the bottom of the pot cover 12. The second flow limiting hole 121 is located at a position corresponding to the ventilation valve 13. The second flow limiting hole 121 is connected to the buffer cavity 133 for ventilation and limiting the outflow of drinking water from the buffer cavity 133.

[0050] During the use of the water storage container 1, it is inevitable that abnormal conditions will occur, such as shaking and changes in internal pressure, which may cause a small amount of drinking water to gush out from the ventilation channel. The small amount of drinking water that gushes out enters the buffer chamber 133 through the internal air channel 134 and is temporarily stored in the buffer chamber 133, thereby avoiding or reducing the overflow of drinking water due to abnormalities. In addition, the second flow-limiting hole 121 can block the drinking water, prevent or reduce the outflow of drinking water from the buffer chamber 133, and enable the drinking water to be stably stored in the buffer chamber 133.

[0051] In addition, for some more severe abnormal conditions, the reference overflow is more severe and the overflow amount is larger. In some improved embodiments, such as Figure 6 As shown, the water storage container 1 further includes an overflow plug 14 disposed in the buffer cavity 133. The overflow plug 14 is provided with a wedge-shaped cap 141. The tip of the wedge-shaped cap 141 points to the inner airway 134. The tip of the wedge-shaped cap 141 is provided with a ventilation gap 142. In more severe abnormal conditions, drinking water quickly flows through the inner airway 134 to the buffer cavity 133. The overflow plug 14 is compressed by the water flow, and the tip of the wedge-shaped cap 141 is deformed and closed, thereby blocking the entire ventilation channel to prevent the drinking water from overflowing rapidly.

[0052] In some embodiments of the vent valve 13 , the vent valve 13 includes a bolt portion 131 and a nut portion 132 connected to the bolt portion 131 , the bolt portion 131 is provided with a buffer chamber 133 , and the nut portion 132 is provided with an inner air passage 134 .

[0053] Regarding the specific parameters of the inner air passage 134 and the second flow restriction hole 121, the diameter of the inner air passage 134 is 0.5 to 1.5 mm, and the diameter of the second flow restriction hole 121 is 1 to 4 mm.

[0054] In some embodiments of the installation of the vent valve 13 , a valve seat 122 is further provided at the bottom of the pot cover 12 , and the valve seat 122 is arranged at the second flow limiting hole 121 . The vent valve 13 is arranged on the valve seat 122 .

[0055] In addition, in order to seal the water storage container 1, an annular groove is provided at the bottom of the pot cover 12. The water storage container 1 also includes a sealing gasket 15, which is arranged in the annular groove. When the pot cover 12 is connected to the kettle 11, the kettle 11 abuts against the sealing gasket 15, so that the kettle 11 and the pot cover 12 can be sealed and assembled.

[0056] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
