The water in thetray component 20 is used for the pet to drink, the water in thetray component 20 naturally flows into thedrinking water tank 30, under the action of thepump component 40, the water in thedrinking water tank 30 is pumped out by thewater pump 42 and pumped into thetransit water tank 60, and after the water in thetransit water tank 60 is heated or cooled by thetemperature control component 50, the water enters thetray component 20 under the action of the water pump 42 (under the action of thewater replenishing pump 41 in other technical schemes). Thewater storage tank 70 continuously supplies water into theintermediate water tank 60.

Thetray assembly 20 includes adrinking tray 21, afilter tray 22, and aretainer tray 23 stacked from top to bottom. The edge of thedrinking tray 21,filter tray 22 ortray 23 may extend and rest on the edge of thedrinking water tank 30.

The center of thedrinking water tray 21 is provided with awater inlet 211. Thewater inlet pipe 33 is connected to thewater inlet 211, and water pumped out of thepump assembly 40 passes through thewater inlet pipe 33 and thewater inlet 211 into thedrinking water tray 21. Thedrinking water tray 21 is similar to a disc, an opening, namely awater outlet 212 is formed in the periphery of thedrinking water tray 21, atray body 213 extends between thewater inlet 211 and thewater outlet 212, and water flows from thewater inlet 211 to thewater outlet 212 in thetray body 213, so that the drinking water tray is similar to natural running water and can improve the drinking interest of pets. The lowest point of thewater outlet 212 is higher than the bottom surface of thetray body 213 by a certain distance, so that a certain amount of water is accumulated in thetray body 213.

The centers of thefilter disc 22 and thesupport disc 23 are provided with openings, and the periphery of thewater inlet pipe 33 is sleeved with the openings. Thefilter tray 22 is sandwiched between the drinkingtray 21 and theretainer tray 23. Thefilter disc 22 is provided with densely distributed through holes for water to flow through, and thefilter disc 22 can be internally provided with filter elements such as activated carbon and sponge so as to purify water and remove impurities mixed in when the pet drinks the water. The water is filtered and then collected in thetray 23. The central hole of the bearingtray 23 is in clearance fit with thewater inlet pipe 33, water can flow out of the tray assembly from the clearance and enter thecontent space 31 of thedrinking water box 30, the bearingtray 23 is also provided with densely distributed outflow holes, the sound of the water flowing out of the bearingtray 23 in the clearance and the outflow holes and entering thedrinking water box 30 is very small, the mute effect is achieved, and pets drinking water can not be disturbed.

Thedrinking water tank 30 continuously stores water naturally flowing from the tray assembly. Thedrinking water tank 30 is provided with awater pump 42, and thewater pump 42 pumps water in thedrinking water tank 30 into thetransit water tank 60 for heating and then flows into thetray assembly 20 and further flows into thedrinking water tank 30. Thus, a circulation loop is formed.

The water is heated or cooled by thetemperature control assembly 50 in theintermediate water tank 60 in the circulation loop.

Thedrinking water tray 21 may also have a structure in which, as shown in fig. 2, thetray body 213 near thewater inlet 211 is at a horizontal high point, the height of thetray body 213 is gradually reduced from thewater inlet 211 to thewater outlet 212, and thewater outlet 212 is naturally formed by the edge of thetray body 213. At this time, the water flow has different heights on the surface of thetray body 213, which is suitable for the drinking water requirements of pets with different sizes.

Thetemperature control assembly 50 comprises asemiconductor chilling plate 51, aheat conducting mechanism 52 and awind mechanism 53.

One surface (refrigerating surface or heating surface) of thesemiconductor refrigerating sheet 51 is attached to the outer wall of thetransit water tank 60, and the water in thetransit water tank 60 is heated through heat conduction. In order to improve the heating efficiency, the wall of theintermediate water tank 60 corresponding to thesemiconductor chilling plate 51 may be made of a metal material with good thermal conductivity.

The other surface of thesemiconductor cooling sheet 51 is closely attached with aheat transfer mechanism 52 and awind mechanism 53. Theheat conducting mechanism 52 and thewind mechanism 53 carry away the hot air or the cold air generated at the other side of thesemiconductor chilling plate 51, so as to ensure the cooling or heating efficiency of thesemiconductor chilling plate 51.

Theheat conducting mechanism 52 may be a heat conducting metal plate, and in this embodiment, theheat conducting mechanism 52 is a heat conducting fin made of an aluminum alloy material for increasing the heat conducting performance.

Thewind mechanism 53 can generate wind, and thewind mechanism 53 can be a fan or other device capable of generating wind. To blow air off the surface of the heat conducting means 52.

Thetemperature control assembly 50 may further include a temperature controller (not shown) including a temperature sensor, a preset temperature may be set in the temperature controller, and when the temperature sensor detects that the water temperature is higher than the preset temperature, the temperature controller cuts off power supply to keep the temperature constant at a value. In general, the temperature controller may not be provided, for example, the temperature of the water is substantially constant by setting the power of the semiconductor cooling plate.

In this embodiment, two wires for connecting thesemiconductor refrigeration sheet 51 to a power supply may also be exchanged, so that thesemiconductor refrigeration sheet 51 converts heating into refrigeration for water in thetransfer water tank 60. The occasion is suitable for hot weather, and the drinking water needs to be cooled.

In the circulation loop, the water pumped into thetransit water tank 60 from thesuction pump 42 is heated by thetemperature control assembly 50 and then flows into thetray assembly 20 for the pet to drink, and the pet drinks warm water, which is beneficial to health.

Besides thetransit water tank 60, a heat insulation member, such as foam or cotton cloth, can be preferably arranged, so that heat loss can be prevented, and an energy-saving effect can be achieved.

A rectifier can be arranged between thesemiconductor refrigeration piece 51 and the 220V alternating current power supply and converts high-voltage alternating current into low-voltage direct current, so that accidents can not happen even if a pet bites the electric wire, and the safety is higher.

Awater storage tank 70 is arranged above thetransfer water tank 60, and the water outlet end of thewater storage tank 70 is connected with thetransfer water tank 60. Water consumed in the circulation circuit by the pet for drinking and evaporation, etc. can be supplied through thewater storage tank 70.

No control valve may be provided between thewater storage tank 70 and thetransfer tank 60. As long as the water outlet end of thewater storage tank 70 is far enough above the water replenishing end corresponding to thetransit water tank 60, the water in thewater storage tank 70 can flow out into thetransit water tank 60 against the pressure of thesuction pump 42 due to the strong water pressure generated by the height difference.

However, the height of thewater storage tank 70 cannot be too high in consideration of the miniaturity of the pet water dispenser, and therefore, afirst check valve 83 is provided between thewater storage tank 70 and thetransfer tank 60. So that water can flow only from thestorage tank 70 to theintermediate water tank 60.

In this embodiment, the pressure generated by thewater pump 42 is relatively high, and due to the pressure generated by thewater pump 42, the water in thewater storage tank 70 does not continuously flow to therelay water tank 60, and only when thewater pump 42 stops working and the water is pumped from therelay water tank 60 by thewater replenishing pump 41, the water in thewater storage tank 70 enters therelay water tank 60 to replenish the water in the circulation loop.

And the water in thecontent space 31 of thedrinking water tank 30 is gradually reduced due to the drinking of the pet, and finally thewater pump 42 can not pump the water, and the circulation loop can not be continued. At this time, thewater pump 42 needs to be stopped for a while, thewater replenishing pump 41 is started to replenish water, thewater replenishing pump 41 pumps the water in thetransit water tank 60 to thetray assembly 20, the water is accumulated in thedrinking water tank 30 after leaving thetray assembly 20, thewater replenishing pump 41 is closed after a sufficient amount of water is accumulated in thedrinking water tank 30, thewater pump 42 is started again, and the circulation circuit is started again. This is also known as the drinking water tank refill process.

In the above-mentioned water tank water replenishing process, thewater pump 42 stops working, thewater replenishing pump 41 pumps out the water in thetransit water tank 60, and thewater tank 70 continuously replenishes water into thetransit water tank 60 because the pressure of thewater pump 42 on thewater tank 70 is released. In order to prevent water from entering thedrinking water tank 30 directly through the path of the deactivated water pump 42 (at which time the pet cannot drink water), asecond check valve 84 is provided between thewater pump 42 and thetransfer tank 60 to prevent water from flowing from thetransfer tank 60 to thewater pump 42 and then directly into thedrinking water tank 30.

The water replenishing process of the drinking water tank can be started manually, for example, when insufficient water storage in thedrinking water tank 30 is observed, thewater suction pump 42 can be turned off manually, thewater replenishing pump 41 can be turned on manually, after thewater replenishing pump 41 works for a period of time to accumulate a sufficient amount of water in thedrinking water tank 30, thewater suction pump 42 can be turned on manually, and thewater replenishing pump 41 can be turned off manually.

In order to automatically start the water replenishing process of the drinking water tank, afloat switch 81 may be disposed in thedrinking water tank 30, and a control end of thefloat switch 81 is connected to thewater pump 42. When thefloat switch 81 detects that the water level reaches a certain low point, thewater pump 42 is turned off through the control end, and thewater pump 42 cannot be started through thefloat switch 81 after thewater pump 42 is turned off, thewater pump 42 needs to be manually started, and water can be automatically supplemented through the pressure generated by the height of thewater storage tank 70 or supplemented through the operation of thewater supplementing pump 41 after thewater pump 42 is stopped. Further, in this embodiment, the other control end of thefloat switch 81 is connected to thewater replenishing pump 41, so that thewater replenishing pump 41 is turned on to replenish water while thewater pump 42 is turned off by thefloat switch 81.

In order to automatically turn off the water replenishing process, a delay circuit (not shown) may be further disposed on the basis of thefloat switch 81, the delay circuit is connected to thefloat switch 81, and thefloat switch 81 turns on thewater pump 42 again at a certain time after automatically turning off thewater pump 42. A time delay circuit is provided to operate thewater replenishment pump 41 for a period of time, such as one and a half minutes, after which a sufficient amount of water has accumulated in thedrinking water tank 30.

The delay circuit may be a circuit provided in a commercially available delay switch.

In this embodiment, the water outlet end of thewater storage tank 70 is higher than thetransfer water tank 60, and the water outlet end of thewater storage tank 70 continuously applies pressure to thetransfer water tank 60, so that the water in thewater storage tank 70 flows into thetransfer water tank 60 for water replenishment due to the action of gravity. In other embodiments, the height of thewater storage tank 70 may not be limited, such as reducing the height of thewater storage tank 70, making the water outlet of thewater storage tank 70 flush with theintermediate water tank 60, and providing a pressure source in thewater storage tank 70 to keep the water outlet of thewater storage tank 70 continuously pressing on theintermediate water tank 60.

In other technical solutions, even thewater storage tank 70 may not be provided, but the household faucet is connected to thetransfer water tank 60 corresponding to the water replenishing port of thewater storage tank 70. When the household faucet is connected to theintermediate water tank 60, theintermediate water tank 60 is also continuously pressurized, and once the pressure of the water pump is relieved, the water in the household faucet flows into theintermediate water tank 60 for automatic water replenishing.

In this embodiment, the water circulation is mainly performed by thewater pump 42, thewater replenishing pump 41 is in a stop state during the normal water circulation, and thewater replenishing pump 41 operates and thewater pump 42 stops operating during the water replenishing of the drinking water tank. That is, thewater pump 42 and thewater replenishing pump 41 are alternately operated.

In other technical schemes, in order to improve the circulating power, thewater pump 42 and thewater replenishing pump 41 can work simultaneously during the water path circulation, and thewater pump 42 and thewater replenishing pump 41 only need to have the same working efficiency, namely the water pump and the water replenishing pump water with the same volume in unit time; when the drinking water tank is used for replenishing water, thewater suction pump 42 stops working, and thewater replenishing pump 41 continues working; after the water supply is completed, thewater pump 42 resumes its operation, and performs water circulation together with thewater supply pump 41.

Since the water in thestorage tank 70 is exhausted, awater level sensor 85 is provided in therelay water tank 60 for safety, and the water level in therelay water tank 60 is sensed by thewater level sensor 85.

Additionally, asolenoid valve 82 may also be provided between thetray assembly 20 and thetransfer tank 60. Thesolenoid valve 82 is provided between therelay water tank 60 and the water replenishment pump 41 (as in the present embodiment), or between thewater replenishment pump 41 and thetray assembly 20.

Thewater level sensor 85 is connected to a controller (not shown), and the control end of the controller is connected to thesolenoid valve 82. When thewater level sensor 85 senses that the water level in thetransit water tank 60 is not sufficient, thesolenoid valve 82 is closed, so that the water in thetransit water tank 60 cannot flow out, thereby preventing thetransit water tank 60 from being burnt out by thetemperature control assembly 50. When thewater level sensor 85 senses that a certain water level is satisfied in thetransit water tank 60, thesolenoid valve 82 is opened, and the circulation of the water path is recovered to be normal.

In this embodiment, thetemperature control assembly 50 includes asemiconductor cooling plate 51, aheat conducting mechanism 52 and awind mechanism 53. Thesemiconductor cooling plate 51 is a cooling device composed of semiconductors, and when a current passes through a thermocouple pair formed by connecting an N-type semiconductor material and a P-type semiconductor material, heat transfer occurs between the two ends, and the heat is transferred from one end to the other end, thereby generating a temperature difference to form a cold-hot end. And the cold and hot ends can be reversed by switching the direction of the current. The cold end or the hot end of the semiconductor refrigerating sheet can refrigerate or heat water. The semiconductor refrigeration sheet is commonly used for air conditioning equipment, and is not easy to think about when being used for a pet water dispenser. Thetemperature control assembly 50 can heat or cool the drinking water. The water can be heated in winter and cooled in hot summer, so that the applicability is wider.

In this embodiment, thefloat switch 81, thesolenoid valve 82, thefirst check valve 83, thesecond check valve 84, and thewater level sensor 85 together form thecontrol unit 80.

In this embodiment, withtransit water tank 60 set up alone, make and carry out the water route circulation between drinking-water tank 30 and thetransit water tank 60, heat water intransit water tank 60, separate between accusetemperature subassembly 50 and the drinking-water tank 30, accusetemperature subassembly 50 can not lead to the fact the injury to the pet, can protect pet safety.

In this embodiment, thewater storage tank 70 is provided to automatically replenish water, so as to satisfy the drinking water demand of the pet when the owner leaves home for a long time. And a control valve is not needed to be arranged between thewater storage tank 70 and thetransfer water tank 60, or only onefirst check valve 83 is needed to be arranged, so that the structure is simpler.
