Detailed Description
The invention discloses a novel water supply assembly 1 applied to a pet water dispenser 4, a water supply system 3 and the pet water dispenser 4 with the water supply system 3.
1. Water supply assembly 1:
as shown in fig. 1, 4-8, the water dispenser comprises a water supply pipe 2 and a one-way water valve 100, wherein the upper end of the water supply pipe 2 is connected to a water supply chamber 35 positioned at the upper part in a case 41 of the water dispenser in a sealing manner, and the one-way water valve 100 is assembled at the lower end of the water supply pipe 2 and immersed in a water storage tank 42 of the water dispenser. The one-way water valve 100 is provided to enable the water supply assembly 1 to smoothly lift water in the water storage tank 42 into the water supply chamber 35 provided at the top of the cabinet 41 when the water pump 32 (the water pump 32 is preferably the impeller 323 type water pump 32) provided at the top of the cabinet 41 of the water dispenser is in an operating state, and clean water in the water supply chamber 35 is injected into the water drinking tray 43 of the water dispenser through the water outlet 375 provided at the side wall of the water supply chamber 35.
After the water is continuously injected into the water tray 43 for a period of time, the water pump 32 stops working and is in a standby state, and at this time, the one-way water valve 100 can enable water in the water supply pipe 2 to remain in the water supply pipe 2, that is, although the water pump 32 stops working, the water level in the water supply pipe 2 does not drop, which also provides a medium for water pulling for the impeller 323 when the water pump 32 is started next time. When the water pump 32 is started to operate, the impeller 323 placed in the water supply chamber 35 makes the water in the water supply pipe 2 flow upward, and the upward flowing water makes the upper and lower ends of the water supply pipe 2 form a negative pressure difference, so that the one-way water valve 100 is opened and the water in the water storage tank 42 is continuously sucked into the water supply pipe 2.
The water supply assembly 1 has the advantages of simple structure, stable water supply, low noise and no fear of temporary power failure, and can automatically and regularly supply water to the water drinking disc 43 especially when a pet owner goes out for a long time and is unattended.
The specific structure of the one-way water valve 100 in the water supply assembly 1 of the present invention is described in detail in the fourth section that follows.
2. And a water supply system 3:
1. structure of the

The water pumping device is packaged in a box body and comprises a main control circuit board 31 and a water pump 32 (comprising a stator 321, a rotor 322 and an impeller 323), wherein the main control circuit board 31 is arranged in the box body and positioned on the inner side of a chamber cover plate above the water pump 32, the stator 321 and the rotor 322 of the water pump 32 are arranged in the middle part of the box body, other spaces in the box body form a water supply chamber 35, the cross section of the water supply chamber 35 is L-shaped, an open water channel 36 is arranged on the bottom plate of the water supply chamber 35, the impeller 323 fixedly connected at the lower end of the rotor 322 is arranged in the open water channel 36, and when the water pumping device is placed in a water accumulation chamber 371, the open water channel 36 is arranged right above a water inlet 372.
The main control circuit board 31, the stator 321 and the rotor 322 installed in the case are water-tightly separated from the water supply chamber 35, and only the impeller 323 installed at the end of the rotor 322 is placed in the water of the water supply chamber 35.
A water outlet 375 is provided at an upper position of the side plate of the water supply chamber 35, and the impeller 323 pumps water in the water supply chamber 35 out of the water outlet 375 to the water tray 43 as the water pump 32 operates.
The UV lamp 33 is disposed in the water supply chamber 35 at a position at the rear side of the impeller 323 (the water outlet end is the rear and the water inlet end is the front), and the UV lamp 33 disinfects the purified water flowing to the water outlet 375.
The water supply chamber 35 is further provided with a water quantity sensor 34 which can indirectly judge the water level in the water storage tank 42 by detecting whether the water supply chamber 35 is lack of water, namely, when the water level in the water storage tank 42 is lower than the position of the water inlet 107 of the one-way water valve 100 in the water supply assembly 1, the running water pump 32 can not suck the water in the water storage tank 42 into the water supply pipe 2, so that no water supply state can occur in the water supply chamber 35.

The return line 381 is sealed from the water supply chamber 35.
2. Using
When the water dispenser is used for the first time, the water cup 5 is used for injecting purified water into the water drinking disc 43 (other automatic water injection devices can be adopted for water injection), water in the water drinking disc 43 flows into the water accumulation cavity 371 through the water injection channel 46 at the side of the water drinking disc 43, and then is injected into the water supply pipe 2 through the water accumulation cavity 371, as the bottom end of the water supply pipe 2 is provided with the one-way water valve 100 (under the gravity of accumulated water in the water supply pipe 2, the one-way water valve 100 is closed), after the water accumulation cavity 371 and the water supply pipe 2 are filled, a box body for packaging the water pumping device is placed into the water accumulation cavity 371, the bottom of the box body is contacted with the cavity bottom of the water accumulation cavity 371, and in the placing process, water in the water accumulation cavity 371 enters the water supply cavity 35 through the open water channel 36 and enables the water level to overflow the impeller 323 of the water pump 32. At this time, the water pump 32 is started to operate, and the water in the water supply chamber 35 is pumped out from the water outlet 375 by the rotation of the impeller 323, so that a negative pressure difference (small upper part and large lower part) is formed at the upper end and the lower end of the water supply pipe 2, and then the one-way water valve 100 is opened, and along with the continuous operation of the water pump 32, the water in the water storage tank 42 is continuously sucked into the water supply pipe 2.
When the water pump 32 stops working (no matter the water supply is manually set to be stopped or the water supply is suddenly stopped by power failure), the impeller 323 stops rotating, at this time, the pressure difference between the upper end and the lower end of the water supply pipe 2 is zero, and the one-way water valve 100 arranged at the lower end of the water supply pipe 2 is closed under the action of the gravity of the water remained in the water supply pipe 2, so that the water in the water supply pipe 2 and the water supply chamber 35 cannot be lost, and the impeller 323 is ensured to be provided with a stimulable water medium when the water pump 32 is started next time.
3. Pet drinking machine 4
As shown in fig. 1-3 and 10, the external contour shape of the pet drinking machine 4 of the present invention may be rectangular, cylindrical or elliptical. It comprises a case 41, a drinking bowl 43 for drinking water for pets and the water supply system 3.
The water storage tank 42 for storing a large amount of drinking water is arranged in the case 41, the top cover 44 is arranged on the case 41, and the water supply system 3 is arranged on one side of the top cover 44.
