The working principle of the present invention:

Continuing to refer to Figures 1 to 6, in this embodiment, the proximity sensing module 4 is installed on the side of the clean water tank close to the drinking tray 21, and this module will be triggered when the head of the pet is above the drinking tray 21, and then the pet is being moved. The information of drinking water is transmitted to the main control module; the main function of this module is to detect whether there is a pet drinking water, that is, to judge whether the change of the water quantity on the drinking tray 21 is caused by the pet drinking water, and then can get rid of the water quantity change caused by other reasons (such as evaporation, Splashing water, etc.), and the module can cooperate with the drinking tray weighing mechanism to count the water consumption of pets; the module can use infrared ranging module, infrared transceiver module, laser ranging module, ultrasonic ranging module, radio frequency identification module (RFID), near-field communication module (NFC), compared with the commonly used human infrared sensor modules on the market (this type of module has a large sensing range, long distance, and inaccurate judgment), this module can accurately judge pets Whether you are drinking water, to avoid misjudgment; the function button module includes physical control buttons, which are used to control the system startup, water change, water replenishment and other operations, and the indicator module can include indicator lights, buzzers, etc. The outside world sends instructions for operations such as replenishing water and changing water, etc.; the communication module can be a wireless communication module, and the wireless communication module can be a WIFI module or a Bluetooth module. When it is a WIFI module, it is connected to an external intelligent terminal via a cloud server. When it is a Bluetooth module, it can be directly connected to an external smart terminal to realize information interaction; meanwhile, in the embodiment, the water outlet 224 is arranged around the drinking tray 21, and the water drained from the water outlet 224 to the drinking tray 21 can be Cover the drinking tray 21 in an all-round way, and then clean it.

Clean water tank mechanism 1: The clean water tank is used to store clean drinking water, and the water volume detection mechanism of the clean water tank is used to detect whether the water volume in the clean water tank is lower than the preset first threshold, so as to replenish water in time. The first threshold needs to be at least greater than the amount of water replenished to the drinking tray 21 once (that is, the empty drinking tray 21 is replenished to the full water threshold), and when the water in the clean water tank is less than or equal to the first threshold, only the drinking tray 21 is replenished with water without changing the water; if the system has the function of cleaning, then the first threshold needs to be at least greater than the total water consumption of one cleaning and replenishment, and when it is less than or equal to the preset value, only the drinking water tray 21 is replenished without changing the water. No cleaning; in this embodiment, the water volume detection mechanism of the clean water tank can be a magnet floating detection module located in the clean water tank, or a weighing mechanism of the clean water tank, or a water level sensing module, wherein the magnet floating detection module includes The magnet float floating on the water surface in the water tank, and the Hall switch installed on the inner wall of the clean water tank, when the water surface in the clean water tank reaches the position of the Hall switch, the magnet float will trigger the Hall switch, and at the same time, the information Feedback to the main control module; the water level sensing module can be a capacitive sensing module installed on the inner wall of the clean water tank, when the water surface reaches a preset height, the capacitive sensor will be triggered, and then the main control module will receive the signal; the clean water tank weighing mechanism (Similar to the weighing mechanism of the drinking water tray) can be installed at the bottom of the clean water tank, and the detection of the water volume in the clean water tank can be realized by weighing the clean water tank.

Water inlet mechanism 22: The water inlet mechanism 22 is used to drain the clean water in the clean water tank mechanism 1 to the drinking water tray 21, so as to achieve functions such as replenishing water, changing water, and cleaning; The water storage capacity is sufficient, and the height of the clean water tank is generally higher than the drinking water tray 21. For this reason, a water inlet control valve is installed on the water inlet conduit 222, which can prevent the water in the clean water tank from flowing to the drinking water tray 21 due to the siphon principle. The water inlet control valve can be a one-way valve or a solenoid valve. When it is a one-way valve, the valve has a certain resistance and needs sufficient water pressure to open, and the pressure of the self-flowing water is not enough to open the valve. , because the water pressure is relatively large, the valve can be pushed open to perform normal water replenishment action. When it is a solenoid valve, the solenoid valve is controlled by the main control module. At the same time, the solenoid valve is closed.

In this embodiment, the annular water channel 223 of the water flow introduction mechanism is arranged on the top of the waste water tank, the drinking tray 21 is located above the waste water tank, and the water pump 221 pumps the water in the clean water tank to the annular water channel 223, inside the annular water channel 223 Under a certain pressure, the water flow can be sprayed onto the drinking tray 21 from several water outlets 224 provided on the inner wall of the annular water channel 223 or its bottom; the position of the water outlet 224 can be appropriately higher than the drinking tray 21. At the same time, the top of the drinking tray 21 can be designed as a concave structure, and the surface is smoothed, so that the water flow can flow from the edge of the drinking tray 21 to the drain 241; in addition, A plurality of water outlets 224 are provided, and the plurality of water outlets 224 are distributed in a circumferential direction, mainly to facilitate the control of water flow to realize cleaning of the drinking tray 21 without dead ends. At the same time, this design can effectively control the water pressure inside the annular water channel 223, so that all The water outlet 224 evenly discharges water, and also avoids that when the pressure is too high, the water flow is rapidly sprayed onto the drinking tray 21, and then splashed to the outside; in a preferred embodiment, the top of the drinking tray 21 is provided with annular steps, and the water outlet 224 is opened towards the direction of the annular step (opening downward). When the water flows out from the water outlet 224, it will be bifurcated on the surface of the drinking tray 21 through the annular step to achieve a better cleaning effect. The drinking tray 21 can be stored for a certain period of time. A large amount of water is convenient for pets to drink, and the water quantity in the drinking tray 21 can be detected by the drinking tray water quantity detection mechanism 23, so as to perform actions such as replenishing water and changing water; The drinking tray weighing mechanism at the bottom of the drinking tray 21 can detect the weight information of the drinking tray 21 and transmit it to the main control module, thereby realizing the detection of the amount of water in the drinking tray 21. part 248 and is sleeved on the outside of the rotating shaft 246, and is in contact with the bottom of the sealing assembly. When the weight of the drinking tray 21 changes, it will press down the weight conducting link 231, and the deformation detector 233 (in this embodiment, a deformation resistance ) detects the pressure change of the weight transmission connecting rod 231, and then obtains the weight of the drinking tray 21 according to the pressure change value. In addition, the drinking tray water volume detection mechanism 23 can also use a water level sensing module or a magnet floating detection module. The above-mentioned principle of detecting the water volume of the clean water tank is similar and will not be repeated here.

Drainage mechanism 24: The water on the drinking water tray 21 can flow into the waste water tank through the drain port 241 and the water flow opening 244. The waste water tank is used to receive the discharged waste water, which is an optional scheme of this technology, and is used to receive the discharged waste water. Other technical means, for example, connect with the external pipeline and discharge directly, or, do not need to communicate directly through the water flow guide groove 249 of the outer wall of the sealing fixture 248 to be discharged to the external water container, the sewer in the house, etc., so that the clean water tank can be It is separated from the waste water tank to avoid water flow circulation, prevent secondary pollution of water flow, and then affect the health of pets; the sealing assembly is connected with the sealing driving mechanism, and the sealing driving mechanism can drive the rotating sealing part 243 to rotate relative to the fixed sealing part 242 to open or close the water flow opening 244, and then open or block the drain port 241 (in this embodiment, the diameter of the water flow opening 244 is greater than or equal to the diameter of the drain port 241, which can increase the flow of drainage, thereby avoiding blockage, and ensuring the unimpeded discharge of pet hair. to the waste water tank), and the outer wall of the fixed sealing part 242 is provided with a water flow guide groove 249 corresponding to the water flow opening 244, which can drain the discharged water; in this embodiment, the rotating sealing part 243 adopts a rotating ceramic valve plate, fixed The sealing part 242 adopts a fixed ceramic valve plate, but in specific use, other materials or other sealing components (ball valve, solenoid valve, sealing plate, etc.) can also be used, which is not limited here, specifically:

One end of the rotating shaft 246 of the sealing drive mechanism is inserted in the sealing fixture 248 and connected with the rotary sealing part 243 through the rotary transmission part 245 (in this embodiment, the bottom of the rotary sealing part 243 is provided with a slot, and the rotary transmission part 245 The top is inserted in the slot); in the initial state, the water flow opening 244 between the rotary sealing part 243 and the fixed sealing part 242 is in a closed state, at this time, the water flow on the drinking tray 21 will not flow out from the water flow opening 244, so that For pet drinking water, when the water needs to be changed, the rotating motor 247 drives the rotating sealing part 243 to rotate relative to the fixed sealing part 242 through the rotating shaft 246 and the rotating transmission part 245 to open the water flow opening 244. At this time, the water on the drinking tray 21 can pass through The drain port 241 and the water flow opening 244 flow out to the outside.

Wastewater tank mechanism 3: The wastewater tank is used to store polluted water. The wastewater tank water volume detection mechanism can be used to detect whether the water volume in the wastewater tank is greater than or equal to the preset second threshold. The module transmits the information that the waste water tank needs to be poured to the outside world. The user can drain the water in the waste water tank to the outside. Because the water source is not circulated, the secondary pollution of the water source can be avoided, thereby ensuring the health of pets; the water volume detection of the waste water tank The mechanism can be a magnet float detection module, or a waste water tank weighing mechanism, or a water level sensing module, which is similar to the above principle and will not be repeated here.

First of all, it is necessary to judge whether the main control module has determined that the clean water tank is empty. If it has been determined, the main control module will detect whether the water volume in the clean water tank is less than or equal to the preset first Threshold, if it is, it means that the water in the clean water tank is insufficient, and water needs to be replenished in the clean water tank, that is, the main control module transmits the information that the clean water tank needs to be replenished to the outside through the communication module or the indicator module, and the first threshold must be at least greater than The amount of water replenished to the drinking water tray 21 at a time (that is, the empty drinking water tray 21 is replenished to the full water threshold), when the water yield in the clean water tank is less than or equal to the first threshold value, only the drinking water tray 21 is replenished without changing the water; if The system has the function of cleaning, then the first threshold must be at least greater than the total water consumption of one cleaning and replenishment, and when it is less than or equal to the preset value, only replenish water to the drinking tray 21 without changing the water or cleaning; if it is greater than the first threshold A threshold value means that the water volume in the clean water tank is sufficient, and the next step is to determine whether the water in the waste water tank needs to be discharged, that is, the main control module detects whether the water volume in the waste water tank is greater than or equal to the preset second value through the waste water tank detection mechanism. Threshold value (the second threshold value is at least less than the water volume of one drinking water tray 21, and no water is changed when it is greater than or equal to the preset value. If it has a cleaning function, the preset value needs to be at least less than the water volume of one cleaning. When setting the value, the drinking water tray 21 does not change water or clean), if so, it means that the water in the waste water tank is full and needs to be discharged, that is, the main control module transmits the information that the waste water tank needs to pour water to the outside through the communication module or the indication module , if not, it means that the remaining volume of the waste water tank is still sufficient, and drainage is not needed, and the next step is to judge whether the drinking water tray 21 meets the water changing condition.

In this embodiment, the water changing condition can be that the storage time of the water in the drinking tray 21 reaches the preset water changing time threshold, or the number of water supplements exceeds the preset water replenishing times threshold, or the water volume in the drinking tray 21 reaches the preset threshold. Set the cleaning threshold (the remaining water on the drinking tray 21 is seldom, but generally it will be dirty, so this part of the water will be replaced), or actively change the water with one key through the function button module, or change the water on the external smart terminal Set the time for automatic water change on the computer, or detect the amount of water the pet drinks and the number of times of drinking through the weighing mechanism of the drinking tray (the continuous change of the water amount is counted as drinking once), and then set the threshold of drinking times according to the data. When the threshold of drinking times is reached, that is Start water change; when the main control module judges that the drinking water tray 21 needs to be changed according to the preset water changing conditions, the main control module controls the sealing drive mechanism to open the drain port 241 to discharge the waste water in the drinking water tray 21 to the waste water box, and control the drinking water tray water volume detection mechanism 23 to detect whether the water volume in the drinking water tray 21 reaches the preset empty water threshold, if so, control the water inlet mechanism 22 to evenly drain the water in the clean water tank to the surface of the drinking water tray 21 to Clean it, and after the cleaning is completed, control the sealing drive mechanism to close the drain port 241, then, the main control module controls the water inlet mechanism 22 to continue to drain the water in the clean water tank to the drinking tray 21, and pass through the drinking tray The water quantity detection mechanism 23 detects whether the water quantity in the drinking water tray 21 reaches the preset full water threshold, if so, the main control module controls the water inlet mechanism 22 to stop working, if not, then needs to detect whether the water quantity in the clean water tank is sufficient.

If it has not been judged that the clean water tank is in an empty water state, then the main control module detects whether the water quantity on the drinking tray 21 is less than or equal to the preset water replenishment threshold through the drinking tray water quantity detection mechanism 23, and the water replenishment threshold can be less than the water replenishment threshold of the drinking water tray 21. The full water threshold can also be equal to the full water threshold (that is, as long as the water in the drinking tray 21 is slightly less, the water will be replenished). The difference between the two is that the frequency of water replenishment is different. The larger the value, the lower the water replenishment frequency. If it is less than or equal to the water replenishment threshold, it is necessary to replenish water into the drinking water tray 21, that is, the main control module controls the water inlet mechanism 22 to divert the water in the clean water tank to the drinking water tray 21, and through the drinking water The tray water quantity detection mechanism 23 detects whether the water quantity in the drinking tray 21 reaches the preset full water threshold, if so, the main control module controls the water inlet mechanism 22 to stop working, if not, then the main control module judges the time for replenishing water to the drinking tray 21 Whether it exceeds the preset time threshold, if so, it indicates that the water quantity in the clean water tank is insufficient, that is, the main control module determines that the clean water tank is in an empty state, and controls the water inlet mechanism 22 to stop working, and sends out that the clean water tank needs to replenish water In addition, when the proximity sensing module 4 detects that the pet is drinking water, the drinking tray 21 does not change the water to avoid affecting the pet's drinking water, which is convenient and practical.
