[0038] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0039] Research has found that existing pet drinking fountains are noisy, especially when the accumulated water in the drinking trough is recycled into the water tank, there is a problem of loud water flow noise.

[0040] To do this, please refer to Figure 1 and Fig.12 As shown, in this embodiment, the utility model designs a silent pet drinking fountain, which includes: a drinking trough 1, a water tank 2 and a water pump, the drinking trough 1 is arranged on the top of the water tank 2, and the water pump is arranged in the water tank 2; wherein, the drinking trough 1 includes an upper shell 11 and a lower shell 12, and the upper shell 11 is sleeved on the lower shell 12, and a lower water cavity 14 is provided between the upper shell 11 and the lower shell 12, and at the same time, a water inlet 111 and a water outlet 112 connected to the lower water cavity 14 are provided on the upper shell 11, and a water return port 122 is provided on the lower shell 12, and the upper and lower ends of the return port 122 on the lower shell 12 are respectively connected to the lower water cavity 14 and the water tank 2.

[0041] From the above description, it can be seen that in this embodiment, the silent pet drinking fountain is optimized for the structure of its own drinking trough 1. The drinking trough 1 is controlled to include an upper shell 11 and a lower shell 12, and a lower water chamber 14 is provided between the upper shell 11 and the lower shell 12, so that the accumulated water on the surface of the upper shell 11 can first flow into the lower water chamber 14 from the water outlet 112, and then be buffered in the lower water chamber 14, and then flow into the water tank 2 from the return water port 122 of the lower shell 12, which plays a buffering role for the water flow, so that it will not directly flow back and fall into the water tank 2, which can effectively reduce noise.

[0042] Accordingly, see Fig.12It can be seen that in this embodiment, a water pipe 32 is further provided at the drain outlet of the water pump of the silent pet water dispenser, and the water pipe 32 passes through the return water port 122 provided on the lower shell 12, and is connected with the water inlet 111 on the upper shell 11, and the notch area of ​​the return water port 122 is larger than the cross-sectional area of ​​the water pipe 32; wherein, a plurality of guide grooves 321 are provided on the outer side wall of the water pipe 32, and the plurality of guide grooves 321 are all extended along the length direction of the water pipe 32, that is, along the vertical height direction (see Fig.12 shown).

[0043] like Fig. 9 , Fig.10 As shown, the reason why multiple guide grooves 321 are arranged on the outer wall of the water pipe 32 is that: the guide grooves 321 can play a role of guiding, that is, when the fluid in the lower water chamber 14 flows back to the water tank 2 from the return water port 122 of the lower shell 12, it can flow along the water pipe 32 in the guide grooves 321 arranged on the outer wall of the water pipe 32, thereby returning to the water tank 2, and avoiding the huge noise generated when falling directly into the water tank 2 from the return water port 122.

[0044] At the same time, when installing the water pipe 32, the reason why the notch area of ​​the water return port 122 is set to be larger than the cross-sectional area of ​​the water pipe 32 is to ensure that there is a gap between the water pipe 32 and the water return port 122, so that the fluid can flow from the water return port 122 to the guide groove 321 on the side wall of the water pipe 32. In this embodiment, in order to obtain a better diversion effect, the groove edge of the guide groove 321 set on the outer wall of the water pipe 32 can conflict with the water return port 122, and the multiple guide grooves 321 can be specifically and evenly arranged on the outer wall of the water pipe 32.

[0045] In addition, see Figure 6 It can be seen that in this embodiment, the silent pet water dispenser further includes a filter 13 disposed in the lower water cavity 14. At this time, a groove 121 is provided on the lower shell 12 of the water trough 1. The filter 13 is specifically disposed in the groove 121, and the water return port 122 is also provided in the groove 121. Based on this arrangement, the fluid that needs to flow back from the water return port 122 to the water tank 2 must be filtered by the filter 13, which can optimize the water quality.

[0046] In addition, if Figure 6 See also Fig.12It can be seen that in this embodiment, in order to obtain better noise reduction effect and usage effect, in actual setting, the upper surface of the upper shell 11 of the drinking trough 1 is also controlled to extend in a curved direction around the water inlet 111 to form a multi-faceted raised first inclined surface 4, and the end of the first inclined surface 4 away from the water inlet 111 is connected to the second inclined surface 5, and the second inclined surface 5 is connected to the side wall of the upper shell 11 through the arc-shaped curved surface 6; wherein the inclination angle of the above-mentioned first inclined surface 4 compared to the horizontal plane is greater than the inclination angle of the second inclined surface 5 compared to the horizontal plane; the above-mentioned water outlet 112 is arranged on the arc-shaped curved surface 6 and is arranged away from the water inlet 111.

[0047] In this embodiment, the water outlet 112 is arranged on the arc surface 6 and away from the water inlet 111 in order to ensure that the fluid ejected from the water inlet 111 can have a certain flow stroke, thereby reducing its kinetic energy and reducing noise, and does not directly flow back from the water outlet 112 to the lower water chamber 14.

[0048] It should be noted that, in actual application, the fluid ejected from the water inlet 111 can flow through the first inclined surface 4, the second inclined surface 5 and the arc-shaped curved surface 6 in sequence, thereby reaching the water outlet 112 and flowing back into the lower water cavity 14. In order to obtain a better reflux effect and avoid the problem of excessive noise due to excessive fluid flow rate, in actual application, the inclination angle of the second inclined surface 5 relative to the horizontal plane can be controlled to be 2 to 15°, and the distance between the water outlet 112 and the bottom end of the second inclined surface 5 in the vertical height direction can also be set to be 0 to 10 mm.

[0049] Accordingly, see Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 It can be seen that in this embodiment, a split water tank 2 and a split water pump are specifically designed to separate the stator assembly and the rotor assembly 3 of the split water pump, and the stator assembly and the rotor assembly 3 are respectively arranged in the base 22 and the water storage tank 21, so as to achieve water-electricity separation, ensure that the water pump circuit part is arranged in the base 22 of the water tank 2, and does not contact with the water in the water storage tank 21, so as to ensure that the water in the water storage tank 21 is not charged.

[0050] To this end, in this embodiment, the water tank 2 of the silent pet drinking fountain includes a water storage tank 21 and a base 22, and the water pump includes a rotor assembly 3 and a stator assembly, the stator assembly and the rotor assembly 3 are respectively arranged in the base 22 and the water storage tank 21, and a main control circuit board is also provided in the base 22, and the main control circuit board is electrically connected to the stator assembly; wherein, the water storage tank 21 is arranged on the above-mentioned base 22, and the above-mentioned drinking trough 1 is arranged at the top of the water storage tank 21 of the water tank 2.

[0051] It should be noted that in the present invention, once the water tank 21 of the silent pet water dispenser overturns, it is easy to cause damage to the rotor assembly 3 disposed in the water tank 21, and affect subsequent use. Figure 5 As shown, in order to enhance the stability of the installation of the water storage tank 21, in the above technical solution of the utility model, the outer peripheral wall of the water storage tank 21 can also be arranged to extend from the lower bottom surface of the water storage tank 21 toward the direction close to the base 22, so that the water storage tank 21 obtains a skirt, and the skirt is used to match the above base 22, so that the outer peripheral wall of the water storage tank 21 is sleeved on the base 22. In order to prevent the water storage tank 21 from tipping over, the outer peripheral wall of the water storage tank 21 extends from the lower bottom surface of the water storage tank 21 toward the direction close to the base 22, specifically not less than 15 mm.

[0052] And, further, if Figure 6 As shown, in the silent pet water dispenser described in the utility model, a positioning hole 221 is provided on the upper surface of the base 22, and a positioning column 211 is provided on the lower bottom surface of the water storage tank 21 to match the positioning hole 221. Based on the matching positioning relationship between the positioning column 211 and the positioning hole 221, the connection relationship between the base 22 and the water storage tank 21 can be effectively strengthened, thereby strengthening the stability of the water storage tank 21, and placing the water storage tank 21 to be tilted sideways compared to the base 22.

[0053] Also, see Figure 6 It can be seen that in this embodiment, in order to ensure the normal use of the split water pump, in actual application, the upper surface of the base 22 of the water tank 2 of the silent pet water dispenser is also provided with a receiving hole 222, and the lower bottom surface of the water storage tank 21 is provided with a protrusion 212 corresponding to the receiving hole 222, and the protrusion 212 is provided with a receiving cavity, and the above-mentioned receiving cavity is connected with the inner cavity of the water storage tank 21. Based on this, when the above-mentioned water storage tank 21 is sleeved on the base 22, the protrusion 212 of the water storage tank 21 can be correspondingly inserted into the receiving hole 222 of the base 22; at this time, the operator can set a magnetic part, such as a permanent magnet, in the receiving cavity of the above-mentioned protrusion 212 to serve as a rotor; and set an electromagnetic part, such as an electromagnet, at a position close to the receiving hole 222 on the base 22 to serve as a stator.

[0054] It should be noted that if Figure 8 , Fig. 9 and Fig.10As shown, in the present embodiment, in order to ensure that the rotor assembly 3 can be effectively installed at the corresponding position in the water tank 21, the rotor assembly 3 of the split water pump further includes a base 31, which is detachably arranged in the water tank 21, and a water inlet groove 34 with a side opening is provided on the base 31, and an impeller is provided in the base 31, and the impeller is connected to the magnetic part of the above-mentioned rotor assembly 3; wherein, the above-mentioned base 31 is also provided with a drain outlet, and the above-mentioned water conduit 32 is connected to the drain outlet opened in the above-mentioned base 31.

[0055] Based on this design, when the electromagnet serving as the stator is energized, it can generate a magnetic field, and the magnetic component serving as the rotor can rotate around its own rotor axis under the influence of the magnetic field, thereby driving the impeller connected thereto to rotate, thereby driving the fluid to move. The fluid can be sucked into the base 31 from the water inlet trough 34 of the base 31, and flow to the drain outlet of the base 31, and discharged to the water pipe 32 connected to the drain outlet of the base 31.

[0056] It should be pointed out that if Figure 4 and Fig. 9 As shown, in this embodiment, when the base 31 is actually installed, a mounting wall 213 may be provided in the water tank 21, a bayonet 214 is provided on the mounting wall 213, and a clip 33 is provided on the base 31, so that the clip 33 and the bayonet 214 cooperate to realize the snap connection between the water tank 21 and the base 31, thereby completing the relative fixed positioning of the water tank 21 and the base 31.

[0057] In addition, if Figure 7 As shown, in this embodiment, a pyroelectric sensor 23 can also be set in the base 22 of the silent pet water dispenser. The pyroelectric sensor 23 is electrically connected to the main control circuit board so that the pyroelectric sensor 23 can be used to identify whether a pet appears in the identification area of ​​the pyroelectric sensor 23. Once the pet is identified to be approaching, an open signal can be transmitted to the main control circuit board. The main control circuit board controls the electromagnetic parts of the given sub-assembly to power the rotor assembly 3 of the water pump to start working.

[0058] Of course, based on this design, when the pyroelectric sensor 23 does not detect the pet appearing in the recognition area of ​​the pyroelectric sensor 23, the split water pump of the silent pet drinking fountain is not powered on and does not need to work. The silent pet drinking fountain is in a dormant state, which can greatly improve the battery life of the silent pet drinking fountain.

[0059] Accordingly, in this embodiment, a wireless communication module may be provided, which may include a wifi module and / or a bluetooth module, which is electrically connected to the main control circuit board, so as to wirelessly connect to a cloud server and / or a smart terminal installed with a pet water dispenser control program through the wifi module and / or the bluetooth module, and the user may remotely control the opening or closing of the silent pet water dispenser through the smart terminal. Currently, in actual application, a mechanical switch may also be provided on the silent pet water dispenser, and the user may manually control the mechanical switch to control the opening or closing of the silent pet water dispenser.

[0060] At the same time, in this embodiment, a power supply module can also be provided, and the power supply module is also electrically connected to the main control circuit board for power supply.

[0061] Based on this, Fig.11 and Fig.12 As shown, in this embodiment, under normal conditions, the silent pet water dispenser is in a dormant state, and its split water pump does not work. When the pet enters the detection area of ​​the above-mentioned pyroelectric sensor 23, or the user remotely sends an open command to the silent pet water dispenser, the main control circuit board of the silent pet water dispenser controls the electromagnetic parts in the stator assembly of the above-mentioned water pump to be energized, which generates an electromagnetic field and causes the magnetic parts of the rotor assembly 3 provided in the water storage tank 21 to rotate around its own rotor axis and drive the impeller to rotate, so that the fluid in the water storage tank 21 is sucked into the base 31 by the water inlet 34 with a lateral opening of the base 31.

[0062] At this time, the fluid sucked into the base 31 can be discharged from the drain port on the base 31 to the water pipe 32, and the fluid is directed from the water pipe 32 to the water inlet 111 of the upper shell 11 of the drinking trough 1 and sprayed out, so that the pet can drink water normally. The fluid sprayed from the water inlet 111 can flow to the water outlet 112 opened in the upper shell 11, pass through the water outlet 112, and flow into the lower water cavity 14 between the upper shell 11 and the lower shell 12. The fluid flows to the groove 121 opened on the lower shell 12 and is filtered from the filter element 13. After filtering, it flows from the return water port 122 in the groove 121 to the multiple guide grooves 321 on the outer wall of the water pipe 32, so as to use the diversion effect of the guide grooves 321 to flow downward to the water storage tank 21, thereby completing the circulation of the fluid between the water storage tank 21 and the drinking trough 1.

[0063] To sum up, the silent pet drinking water dispenser designed by the utility model has a simple structure, low cost, good stability, and can achieve silent water return. It can ensure that there is no noise when the accumulated water on the drinking trough flows back to the water tank 2. It has a better user experience and has good promotion prospects and application value.

[0064] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
