Referring now to the drawings, in which like numerals refer to like parts throughout the several views, fig. 1 shows a first embodiment pet drinking fountain 10. Referring to fig. 1 and 2, a pet drinker 10 comprises a water tank 12, the water tank 12 having a bottom wall 14 and a side wall 16 extending upwardly around the periphery of the bottom wall 14, the upper edge of the side wall 16 forming an opening 18 in the water tank 12 so that water can pass into and out of the water tank 12 from the opening 18.

Referring to fig. 4-6, the motor compartment 20 is formed in the bottom of the tank 12, by way of non-limiting example, the motor compartment 20 is formed at the corner of two adjacent side walls 16, in such a way that the two side walls 16, and the side wall 22, the end wall 24 extending upwardly from the bottom wall 14 within the tank 12, and the top wall 26 at the upper edges of the side wall 22 and the end wall 24, enclose the motor compartment 20. A cover 28 is provided at the bottom of the water tank 12 so that the motor chamber 20 can be opened at the bottom of the water tank 12. The motor chamber 20 may be integrally formed with the water tank 12.

A motor 30 is disposed within the motor chamber 20 with a motor shaft 32 extending into the tank 12 through a shaft aperture 34 formed in the end wall 24. In this way, the motor chamber 20 is closed from the water tank 12 except for the shaft hole 34. The heat dissipation hole 36 for dissipating heat of the motor 30 is disposed on the chamber cover 28, and the power cord 38 of the motor 30 extends to the outside through the chamber cover 28, but it is also possible to dispose a power interface (not shown in the figure) on the sidewall 16 or the bottom wall 14 of the water tank 12 instead of the power cord 38, where the power interface is externally connected with a power cord to facilitate the detachment of the power cord, and the power cord may be, for example, a USB interface. The sealing member 40 serves to seal a gap between the shaft hole 34 and the motor shaft 32 to prevent water from entering the motor chamber 20 from the water tank 12. The seal 40 may be, for example, a seal ring and may be disposed on the motor shaft 32.

An impeller 42 and a volute 44 are disposed within the tank 12 outside the end wall 24 of the motor chamber 20, wherein the impeller 42 is connected to the motor shaft 32 and rotates about the axis of rotation of the motor shaft 32. The volute 44 and the motor chamber 20 may be integrally formed or removably connected. The impeller 42 is positioned within the volute 44, the inlet 48 is positioned centrally within the volute 44 and is in fluid communication with the impeller 42, and the outlet 50 is positioned adjacent to a tangential outer side of the impeller 42. In this manner, the impeller 42, volute 44 and motor 30 combination substantially perform the function of a water pump.

A filter housing 52 is disposed outside the inlet 48, and the filter housing 52 and the volute 44 may be integrally formed or removably connected. A filter chamber 54 defined by the filter housing 52 is in fluid communication with the impeller 42 through the inlet port 48 and in fluid communication with the tank 12 through a filter inlet 56. Filter cotton or the like may be placed within the filter chamber 54.

Referring to fig. 2-3, the upper cover 58 removably overlaps the upper edge of the side wall 16 of the tank 12 so that the devices and water inside the tank 12 may not necessarily be visible when the pet water dispenser 10 is assembled. A connection pipe 60 extends downward from the upper cover 58 to communicate above and below the upper cover 58, and has a lower port 62 connected to the water outlet 50 of the scroll 44 and an upper port 64 formed at the top of the upper cover 58. In the present embodiment, the upper port 64 is located proximate an upper edge 66 of the upper cover 58. The upper cap 58 may also be integrally formed with the tank 12 and then water may be injected into the tank 12 through the upper port 64.

A recess 68 is also formed in the top of the upper cover 58 at a location spaced from the upper port 64 such that the upper port 64 is located outside of the recess 68. The groove 68 extends in the longitudinal direction from a location proximate the upper port 64 to a location proximate a lower edge 70 opposite the upper edge 66, and in the transverse direction from a location proximate a left edge 72 of the upper cover 58 to a location proximate a right edge 74 opposite the left edge 72. In this manner, the recess 68 occupies substantially most of the top of the upper cover 58.

A filter tank 76 is formed at the bottom of the groove 68, and a drainage hole 78 is formed at the bottom of the filter tank 76, the drainage hole 78 communicating the upper side and the lower side of the upper cover 58. The filter 80 is placed in the filter tank 76, and a stopper rib 82 for stopping the filter 80 may be formed in the filter tank 76. The water filtering holes 78 have a pore size as small as possible and a number as large as possible, so that the water filtering holes 78 can block large-sized foreign substances from entering the water tank 12 while allowing water to smoothly pass therethrough even when the filter 80 is not used.

Referring to fig. 2, 3 and 7, the drinking tray 84 is placed in the groove 68 with a gap 86 between the outer periphery of the drinking tray 84 and the outer periphery of the groove 68. A plurality of legs 88 extend downwardly from the bottom of the drinking tray 84 and rest on the grooves 68 to support the drinking tray 84 above the bottom of the grooves 68 in such a manner that a gap 90 is formed between the bottom of the drinking tray 84 and the bottom of the grooves 68. The bottom of the recess 68 may be provided with a detent 92 for locating the leg 88 to prevent the drinking tray 84 from being unnecessarily displaced or shaken.

An upwardly extending pilot nozzle 94 is inserted through the upper port 64 and is partially received within the connecting tube 60, the pilot nozzle 94 being in fluid communication with the outlet 50 of the volute 44, either directly with the outlet 50 or indirectly with the outlet 50 via the connecting tube 60. The guided nozzle 94 includes a tubular portion 96 and a head portion 98, the tubular portion 96 being an elongated straight tube having an inner diameter at an inlet end 100 that is less than an inner diameter at an outlet end 102, and the inner diameter decreases from the outlet end 102 to the inlet end 100. The head portion 98 is scoop-shaped with a rear side forming a baffle wall 104, two sides raised to form a ramp 106, a front side forming a flow guide outlet 108, and the outlet end 102 surrounding the baffle wall 104 and the ramp 106 and upstream of the flow guide outlet 108. The spout outlet 108 is located above the drinking water tray 84. Water enters the tubular portion 96 from the inlet end 100 and exits the outlet end 102 and is directed through the head portion 98 to exit the fluid outlet 108.

It should be understood that the pet drinker 10 may be provided without the upper cover 58 and the drinking tray 84 may be attached to the upper edge of the side wall 16 of the tank 12. The filter 80 may be fixed under the drinking tray 84 or the filter 80 may be absent.

When the pet water dispenser is used, a proper amount of water is injected into the water tank 12 through the opening 18, then the pet water dispenser 10 is assembled, the motor 30 is powered on, at the moment, the water in the water tank 12 sequentially passes through the water inlet 48, the impeller 42, the water outlet 50, the connecting pipe 60 (optional) and the diversion nozzle 94 under the rotation of the impeller 42, then flows out of the diversion outlet 108 of the diversion nozzle 94 and falls into the water tray 84, and a pet can drink the water in the water tray 84 or the water on the head part 98 of the diversion nozzle 94. When the drinking water tray 84 is full, it flows through the gap 86 into the recess 68, through the gap 90 into the filter bowl 76, and back into the tank 12 after being filtered by the filter 80 (optional) and the filter holes 78. In this manner, water may circulate within the pet drinker 10.

The motor 122 has a rotor chamber 124 provided corresponding to a through hole 126 on the motor chamber 120, the through hole 126 communicating the water tank 112 and the rotor chamber 124. The gap between the through hole 126 and the rotor cavity 124 is provided with a seal (not shown) to prevent water in the water tank 112 from entering the motor chamber 120 through the gap, and the seal may be, for example, a sealing ring. In this way, water in the water tank 112 can only enter the rotor chamber 124. The motor compartment 120 may be integrally formed with the water tank 112.

An impeller 130 and a volute 132 are disposed in the water tank 122 and outside the motor chamber 120, wherein the impeller 130 has a rotor 134 attached thereto, and the rotor 134 is rotatably received in the rotor chamber 124 through the through hole 126. The rotor 134 is typically made of a permanent magnetic material, and the coils and U-shaped core (not shown) of the motor 122 are disposed around the rotor cavity 124, so that when the motor 122 is energized, the rotor 134 can rotate in the rotor cavity 124 under the action of the magnetic field, thereby rotating the impeller 130.

In use, a proper amount of water is poured into the water tank 112, the pet drinker 110 is assembled, the motor 122 is powered on, and the water in the water tank 12 sequentially passes through the impeller 130 and the diversion nozzle 118 and falls into the drinking tray 116 under the rotation of the impeller 130. When the water tray 116 is full, it can flow back to the water tank 112 through the upper cover 114.

It should be understood that the rotor cavity 124 may be separately formed integrally with the motor compartment 120 and sealingly connected at the through-bore 126 such that there is no gap between the through-bore 126 and the rotor cavity 124 and no seal is required.

The rotor 168 is provided with a rotation shaft 170, one end of the rotation shaft 170 passes through the shaft hole 162 to be connected to the impeller 164, and the other end of the rotation shaft 170 is inserted into a positioning groove 172 (shown in fig. 16) provided in the rotor chamber 154. The rotor 168 is typically made of a permanent magnetic material, and the coils and U-shaped core (not shown) of the motor 152 are disposed around the rotor cavity 154, such that when the motor 152 is energized, the rotor 168 and the shaft 170 rotate within the rotor cavity 154 under the influence of a magnetic field, thereby rotating the impeller 164. Referring to fig. 15 and 16, the sealing ring 174 is used to seal the gap between the shaft hole 162 and the rotating shaft 170 in such a way that water in the water tank 142 cannot enter the rotor cavity 154, and also prevent hair, impurities and the like from entering the rotor cavity 154, thereby preventing the rotor 168 from stopping rotating due to blockage, and preventing the pet drinker 140 from stopping water circulation during use.

The volute 166 is integrally formed with the motor compartment 150, the volute 166 includes a water inlet 176 and a water outlet 178, the volute 166 further includes a removable cover 180, and the water inlet 176 is disposed on the cover 180. The water outlet 178 is in communication with the diversion nozzle 148.

When the pet water dispenser is used, a proper amount of water is filled into the water tank 142, then the pet water dispenser 140 is assembled, the motor 152 is powered on, and at the moment, the water in the water tank 142 sequentially passes through the impeller 164 and the diversion nozzle 148 under the rotation of the impeller 164 and then falls into the water dispenser tray 146. When the water tray 146 is full, it can flow back to the water tank 142 through the upper cover 144.
