The terms "first", "second", etc. in the description and claims of the present utility model or the above drawings are used to distinguish different objects and not to describe a specific order.

[0024] Reference to "embodiment" in the present utility model means that a specific feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of the present utility model. The phrase appears at various positions in the description and does not necessarily refer to the same embodiment, nor is it an exclusive, independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described in the present utility model can be combined with other embodiments.

[0025] In order to enable those skilled in the technical field to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings.

[0026] As Figure 1-6 shown, a pet drinking fountain with a non-powered water replenishing structure according to the present utility model includes a drinking fountain main body 1 and a drinking tray 2. A buffer water receiving assembly and a connecting water pipe 3 are arranged in the drinking fountain main body 1. A water receiving cavity 411 is arranged in the buffer water receiving assembly. A water supply installation position 421 communicated with the water receiving cavity 411 is arranged at the upper end of the buffer water receiving assembly. A water supply installation window matched with the water supply installation position 421 is arranged on the upper end surface of the drinking fountain main body 1. The connecting water pipe 3 is communicated with the water receiving cavity 411, and one end of the connecting water pipe 3 is connected to the drinking tray 2. The buffer water receiving assembly can supply water to the drinking tray 2 through the connecting water pipe 3, and the buffer water receiving assembly can ensure that the water level height in the buffer water receiving assembly is the same as the water level height in the drinking tray 2 through the connecting water pipe 3.

[0027] Through the structural arrangement of the water receiving cavity 411, the connecting water pipe 3 and the drinking tray 2, the principle of communicating vessels can be utilized to make the water level of the water receiving cavity 411 consistent with that of the drinking tray 2. And after the pet drinks the water in the drinking tray 2, the drinking tray 2 can be automatically replenished with water, effectively solving the problems that the existing water supply using a water pump occupies the internal space of the product, has high production costs and generates noise during water supply. With this solution, automatic water supply is ensured while the production cost can be reduced and the user experience can be improved.

[0028] During use, just invert the water bottle 11 from the water supply installation window into the water supply installation position 421. Under the action of gravity, the water in the water bottle 11 flows out from the bottle mouth below the water bottle 11 and into the water receiving cavity 411. The water level in the water receiving cavity 411 gradually rises. When the water level in the water receiving cavity 411 is flush with the flat head, the water in the water bottle 11 stops flowing out under the action of air pressure. When the water level in the water receiving cavity 411 drops, the water bottle 11 continues to replenish water to the water receiving cavity 411, and this cycle is repeated to achieve power-free water replenishment.

[0029] By using the daily drinking water bottle 11 for water supply, it is avoided that, like the traditional built-in water tank structure, due to capacity reasons, water needs to be added frequently, and frequent opening of the lid causes bacteria or dust in the air to enter the water tank, resulting in water source pollution.

[0030] The setting of the water tank-free structure in this solution avoids the water tank occupying the product volume. At the same time, when the user directly uses bottled water for water supply, the effect of replacing the water bottle immediately after use can be achieved, without worrying about the problems of bacteria or pollutants appearing in the water bottle 11 after repeated use, ensuring the cleanliness of the drinking water and avoiding health problems for pets when drinking water.

[0031] The buffer water receiving assembly includes a buffer water receiving cup 41 and a water surface height adjusting assembly. The water receiving cavity 411 is arranged on the buffer water receiving cup 41. An installation position 412 for cooperating with the water surface height adjusting assembly is arranged on the buffer water receiving cup 41. A diversion hole 413 is arranged on the side wall of the buffer water receiving cup 41. A pipe connection part is arranged at a position corresponding to the diversion hole 413 on the outside of the buffer water receiving cup 41. An inlet hole for cooperating with the diversion hole 413 is arranged on the connecting water pipe 3.

[0032] Through the setting of the water surface height adjusting assembly, the relative position height between the bottle mouth and the water receiving cavity 411 can be controlled, that is, the water volume in the water receiving cavity 411 can be adjusted, so as to adjust the water supply volume of the drinking tray 2 by using the principle of communicating vessels.

[0033] The water surface height adjustment assembly includes a water bottle bracket 42 and a rotary adjustment ring 43. A water supply installation position 421 is provided on the water bottle bracket 42. The water bottle bracket 42 is used to hold the water bottle 11. The rotary adjustment ring 43 is sleeved on the water bottle bracket 42. Internal threads are provided on the inner wall of the rotary adjustment ring 43, and external threads matching the internal threads are provided on the outer wall of the water bottle bracket 42. A lifting guide portion 415 is provided on the buffer water receiving cup 41. The lifting guide portion 415 can guide the movement of the water bottle bracket 42 during the lifting process. The water surface height adjustment assembly protrudes from the water supply installation window. The water surface height adjustment assembly can change the height of the water bottle bracket 42 by adjusting the rotary adjustment ring 43.

[0034] Through the setting of the lifting guide portion 415, the lifting limit of the water bottle bracket 42 can be carried out to prevent the water bottle bracket 42 from rotating together with the rotary adjustment ring 43.

[0035] During adjustment, when the rotary adjustment ring 43 is rotated, the water bottle bracket 42 can perform a lifting movement under the cooperation of the internal threads and the external threads.

[0036] When the water bottle bracket 42 rises, the water bottle 11 driven by the water bottle bracket 42 rises, causing the mouth of the water bottle 11 to move away from the water surface in the buffer water receiving cup 41. The water in the water bottle 11 will be replenished, and the increased water will also enter the connecting water pipe 3 through the cooperation of the diversion hole 413 and the water inlet hole until the water surface height in the water receiving cavity 411 is the same as the water surface height of the drinking tray 2. At this time, the water surface height in the water receiving cavity 411 is flush with the mouth height of the water bottle 11, and the water bottle 11 stops replenishing water.

[0037] The positioning portion of the lifting guide portion 415 is a lifting guide block provided in the buffer water receiving cup 41. An installation notch 22 cooperating with the lifting guide block is provided on the water bottle bracket 42, and the lifting guide block is arranged in the installation notch 22.

[0038] Through the cooperation of the lifting guide block and the installation notch 22, the lifting movement of the water bottle bracket 42 becomes more stable.

[0039] This pet drinking fountain with a non-powered water replenishing structure further includes a rotary drive assembly 5. A waste water recovery box 6 is provided on the drinking fountain main body 1. The waste water recovery box 6 is arranged below the drinking tray 2. The rotary drive assembly 5 can drive the drinking tray 2 to rotate by driving the connecting water pipe 3 to rotate and pour the waste water into the waste water recovery box 6. The pipe connection portion is a sleeve 416 provided on the side wall of the buffer water receiving cup 41. The moving end of the rotary drive assembly 5 is connected to the other end of the connecting water pipe 3. At least two sealing members are sleeved on the connecting water pipe 3, and the two sealing members are respectively on both sides of the water inlet hole. The two sealing members can ensure that water flows out from the pipe connection portion during the rotation of the connecting water pipe 3.

[0040] By setting the driving component 5 of the rotation driving component, the pet drinking fountain can be effectively rotated automatically to recycle the waste liquid, improving the user experience.

[0041] During the rotation process, the water inlet hole will rotate upwards, and the water in the diversion hole 413 cannot enter the connecting water pipe 3 from the water inlet hole, effectively preventing the connecting water pipe 3 from continuously replenishing water to the drinking tray 2 during waste liquid recycling.

[0042] A water tray seal is sleeved on one end of the connecting water pipe 3 close to the drinking tray 2. The drinking tray 2 includes a water tray part 21 and a water tray connecting part 22. By setting the water tray seal, it can cooperate with the inner wall of the water tray connecting part 22 to prevent water leakage from the water tray connecting part 22.

[0043] Both the seal and the water tray seal are silicone rubber sealing rings, and the connecting water pipe 3 is provided with a positioning groove for cooperating with the silicone rubber sealing ring.

[0044] By setting the positioning groove, the stability of the positions of the seal and the water tray seal can be effectively improved, ensuring the sealing effect.

[0045] The pet drinking fountain with a non-powered water replenishment structure further includes a switch bottle cap, which is used to be installed on the water outlet of the water storage bottle 11. The switch bottle cap includes a bottle cap main body 7 and a jacking switch assembly. An outlet channel is provided on the bottle cap main body 7. The jacking switch assembly is provided with a jacking seal and a jacking reset part 8. The jacking seal is arranged in the outlet channel, and a jacking part 416 for cooperating with the jacking seal is arranged on the buffer water receiving assembly.

[0046] By setting the switch bottle cap and installing it on the drinking water bottle 11, under the action of the jacking switch assembly, when the drinking water bottle 11 is not installed in the water supply installation position 421, the water will not flow out when it is inverted, avoiding splashing of the water in the bottle 11 when it is not installed in place and affecting the user experience.

[0047] By setting the jacking part 416, it can cooperate with the jacking seal to open the outlet channel, improving the user experience.

[0048] The jacking seal includes a jacking column 9 and a sealing disc 10. The jacking part 416 is a jacking convex block arranged in the water receiving cavity 411. The upper end of the jacking column 9 is connected to the sealing disc 10. The jacking reset part 8 is a jacking reset spring, which is sleeved on the jacking column 9. A spring limit boss 91 is arranged at the lower end of the jacking column 9. The two ends of the jacking reset spring can be limited by the lower end surface of the switch bottle cap and the spring limit boss 91 respectively. The diameter of the sealing disc 10 is larger than the diameter of the outlet channel, and the sealing disc 10 is arranged on the inner surface of the switch bottle cap.

[0049] Through the setting of the jacking bump, after the water bottle 11 is installed in place, the jacking column 9 can be jacked upward, so that the jacking column 9 drives the sealing disc 10 to move upward, the sealing disc 10 moves away from the water outlet channel, and the water outlet channel is opened.

[0050] When the water bottle 11 is taken out, under the action of the jacking return spring, the jacking column 9 resets downward, and the lower end face of the sealing disc 10 blocks the water outlet channel.

[0051] The shape of the sealing disc 10 is frustum-shaped, and the material of the sealing disc 10 is silica gel. The end with a small cross-sectional area of the sealing disc 10 faces the water outlet channel. An installation groove matching with the sealing disc 10 is arranged on the jacking column 9, and an installation block matching with the installation groove is arranged at one end of the sealing disc 10 facing the jacking column 9. The sealing disc 10 can be clamped with the jacking column 9 through the installation block.

[0052] Since the shape of the sealing disc 10 is frustum-shaped and the material of the sealing disc 10 is silica gel, the sealing effect can be better.

[0053] As can be seen from the above, the beneficial effects of the present utility model are as follows: By adopting its mechanism, the problems of large internal occupied space and working noise existing in the water replenishing method using a water pump in the prior art for pet drinking fountains can be effectively solved. After the water bottle 11 is installed in the water supply installation position 421 by using the product structure, the water receiving cavity 411 and the drinking tray 2 can automatically ensure that the water surface heights are consistent, realizing automatic water replenishment, reducing the production cost of the product, and through the cooperation of the water supply installation position 421 and the water supply installation window, the water bottle 11 can be used as a water source, ensuring the cleanliness of the water, improving the user experience, and being beneficial to improving the competitiveness of the product.

[0054] The above-mentioned specific implementation manners are the preferred implementation manners of the present utility model, and do not limit the specific implementation scope of the present utility model.
