Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a pet water dispenser. Background Technology

[0002] Currently, common pet water fountains come in two main types: one type dispenses water from the tank in a fountain-like manner, creating the visual effect of "living water" to attract pets to drink. However, this doesn't actually circulate fresh water and requires manual replenishment. Another type involves periodically emptying the water dish and refilling it with fresh water. However, pets often drop hair and solid debris into the dish while drinking. The frequency of water dish replacement varies depending on the level of contamination. Furthermore, due to environmental dust and oral bacteria from the pet's mouth, a bacterial biofilm grows on the walls of the water dish. Simply emptying the water dish doesn't remove this biofilm, and excessive bacteria in the water can negatively impact a pet's thirst, potentially leading to digestive problems, urinary tract infections, and other issues. Moreover, existing pet water fountains often only have a storage chamber for circulating filtered water. The filtration system takes a considerable amount of time to completely filter the water in this chamber, resulting in low water circulation efficiency. In long-term use, the storage chamber lacks automatic replenishment of clean water, forcing pets to drink only continuously circulating purified water, leading to a less than ideal user experience.

[0004] This utility model is achieved using the following technical solution:

[0005] A pet water fountain includes a main unit, a clean water tank for external water supply, a wastewater tank for wastewater discharge, a drinking tray, a drive mechanism, a circulating water supply mechanism, a filtration mechanism, and a cleaning mechanism. The drinking tray is located on top of the wastewater tank and is connected to the drive mechanism. The drive mechanism drives the drinking tray to rotate along a horizontal axis to pour water from the drinking tray into the wastewater tank. The circulating water supply mechanism transfers clean water from the clean water tank to the drinking tray. The filtration mechanism is installed in the wastewater tank to filter the wastewater poured from the drinking tray. The cleaning mechanism removes dirt from the surface of the drinking tray. The main unit contains a controller electrically connected to the drive mechanism, the circulating water supply mechanism, the filtration mechanism, and the cleaning mechanism.

[0006] Furthermore, the drinking tray includes a water outlet platform and a water holding chamber connected together. The water outlet platform is connected to the water supply port of the main unit. The bottom surface of the water holding chamber is recessed downward to form a groove.

Detailed Implementation

[0026] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0027] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0028] like Figures 1 to 8 As shown, this utility model provides a pet water fountain, including a main unit 1, a clean water tank 2 for external water supply, a wastewater tank 3 for wastewater discharge, a drinking tray 4, a drive mechanism, a circulating water supply mechanism, a filtration mechanism 8, and a cleaning mechanism. The drinking tray 4 is located on top of the wastewater tank 3 and is connected to the drive mechanism. The drive mechanism drives the drinking tray 4 to rotate along a horizontal axis to pour water from the drinking tray 4 into the wastewater tank 3. The circulating water supply mechanism transfers clean water from the clean water tank 2 to the drinking tray 4. The filtration mechanism 8 is installed in the wastewater tank 3 to filter the wastewater poured out by the drinking tray 4. The cleaning mechanism removes dirt from the surface of the drinking tray 4. The main unit 1 contains a controller electrically connected to the drive mechanism, the circulating water supply mechanism, the filtration mechanism 8, and the cleaning mechanism.

[0029] In this embodiment, the clean water tank 2 is used to connect to an external clean water source, ensuring that the clean water tank 2 can be filled with clean water at any time. The wastewater tank 3 is used to receive wastewater poured from the drinking dish 4 and automatically drain the wastewater, avoiding the problem of odor caused by wastewater accumulation. Through the external water supply and drainage design of the clean water tank 2 and the wastewater tank 3, automatic water supply and drainage can be realized, achieving the effect of unattended operation and worry-free and labor-saving. At the same time, in conjunction with the circulating water replenishment mechanism, new clean water can be injected into the drinking dish 4, instead of the traditional repeated circulation of "old water". The cleaning mechanism removes the dirt attached to the surface of the drinking dish 4, ensuring that the water source in the drinking dish 4 is clean. The filtration mechanism 8 filters the wastewater poured out by the rotating drinking dish 4, and intercepts and collects animal hair to prevent animal hair from clogging the drain pipe. The driving mechanism realizes the rotation and tilting of the drinking dish 4, realizing the automatic drainage of wastewater from the drinking dish 4, keeping the water source in the drinking dish 4 clean, thereby ensuring the drinking water safety of pets. By controlling and adjusting the drive mechanism, the circulating water replenishment mechanism, the filtration mechanism, and the cleaning mechanism respectively by the controller, the entire system can be automated and coordinated.

[0030] In a preferred embodiment, the drinking tray 4 includes a water outlet platform 41 and a water holding chamber 42 connected together. The water outlet platform 41 is connected to the water supply port 11 of the main unit 1. The bottom surface of the water holding chamber 42 is recessed downward to form a groove 43. An impeller 51 is provided in the groove 43. The impeller 51 is connected to a pump body 52 that drives it to rotate. The groove 43 is covered by a water spray cover 6. The pump body 52 is electrically connected to the controller. The controller is used to receive the current signal of the pump body 52 and control the operation of the circulating water replenishment mechanism and the drive mechanism according to the current signal.

[0031] In this embodiment, the circulating water replenishment mechanism transfers the purified water in the water tank 2 to the water supply port 11, and then the water supply port 11 transfers the purified water to the water outlet platform 41. The water holding chamber 42 receives the purified water flowing out of the water outlet platform 41. Since the groove 43 in the water holding chamber 42 is equipped with an impeller 51, when the pump body 52 drives the impeller 51 to rotate, the rotation of the impeller 51 will cause the water in the groove 43 to gush out from the spray cover plate 6, achieving a fountain effect to attract pets to drink; the pump body 52 drives the impeller 51 to rotate, and when the impeller 51 rotates... When affected (hair wrapped around impeller 51), the current of pump body 52 will change. The controller monitors the current signal of pump body 52. ​​When the current signal detected by the controller is continuously greater than the safety threshold, the controller will start the drive mechanism, which will drive the drinking tray 4 to rotate. The drinking tray 4 rotates and tilts to pour the sewage in the drinking tray 4 into the sewage tank 3. After that, the drinking tray 4 is reset, and the circulation water replenishment mechanism is started again to replenish the drinking tray 4 with clean water, so as to achieve the effect of automatically emptying sewage and automatically replenishing water in the drinking tray 4.

[0032] In a preferred embodiment, the water spray cover 6 includes a cover cavity 62 with water spray holes 61 and an extension 63 connected to the cover cavity 62. A guide passage is formed between the extension 63 and the groove 43. A filter part 64 is provided at the bottom of the extension 63. The filter part 64 is provided with a plurality of filter holes 65 and is disposed in the guide passage.

[0033] In this embodiment, when the impeller 51 rotates, it causes the water in the groove 43 to gush upward from the spray hole 61 of the cover cavity 62, forming a fountain effect. The filter section 64 is set in the guide passage to intercept and filter hair and dirt entering the guide passage. During the rotation of the impeller 51, hair and residue in the water chamber 42 are adsorbed onto the filter section 64. Larger hair and residue are intercepted by the filter section 64, while smaller hair is adsorbed and wrapped around the impeller 51. When a lot of hair is wrapped around the impeller 51, the rotation of the impeller 51 will be affected, which will in turn affect the current change of the pump body 52. ​​After the controller receives the current change, it will start the drive mechanism, which will drive the drinking water turntable to rotate. Then the drinking water tray 4 will rotate and tilt, pouring the sewage on the drinking water tray 4 into the sewage tank 3, and filtering the sewage through the filter mechanism 8. In this way, the hair is intercepted on the filter mechanism 8 to prevent the drain pipe from being blocked.

[0034] In a preferred embodiment, an inclined guide surface 44 is formed at the end of the groove 43 away from the impeller 51, and the inclined guide surface 44 is connected to the guide path.

[0035] In this embodiment, by setting an inclined guide surface 44, the hair or dirt in the water chamber 42 is guided to flow in the direction of the guide path, thereby intercepting and collecting the hair or dirt in the water chamber 42 to prevent the hair or dirt from affecting the pet's drinking.

[0036] In a preferred embodiment, the circulating water replenishment mechanism includes a diaphragm pump 91 installed in the main unit 1. The main unit 1 is provided with a water supply port 11 that communicates with the drinking tray 4. The outlet end of the diaphragm pump 91 is connected to the water supply port 11, and the inlet end of the diaphragm pump 91 is connected to the water pumping connector 21 of the water purification tank 2. A solenoid valve 92 is installed on the inlet end of the diaphragm pump 91. The solenoid valve 92 and the diaphragm pump 91 are electrically connected to the controller.

[0037] In this embodiment, the diaphragm pump has an inlet and an outlet. The outlet is connected to the water supply port 11 via a water path. Water exiting the diaphragm pump is delivered to the drinking basin 4 through this water supply port 11. The inlet of the diaphragm pump is connected to the water pumping connector 21 of the purified water tank 2, meaning the diaphragm pump draws water from the purified water tank 2. A solenoid valve 92 is installed at the inlet of the diaphragm pump, which controls the flow of water. The controller controls the opening and closing of the solenoid valve 92 and the diaphragm pump to automatically regulate the water supply of the entire device.

[0038] Specifically, the controller controls the start and stop of the solenoid valve 92 based on the current signal received from the pump body 52. ​​If the current signal received by the controller from the pump body 52 is greater than the preset threshold, the controller controls the solenoid valve 92 and the diaphragm pump 91 to start. The diaphragm pump 91 draws clean water from the water tank 2 and pumps the clean water to the water supply port 11. The clean water flows from the water supply port 11 into the water outlet platform 41 of the drinking tray 4, and then from the water outlet platform 41 into the water holding chamber 42, thus realizing the automatic water replenishment function.

[0039] In a preferred embodiment, the drinking tray 4 further includes a receiving cavity 45 for storing the pump body 52, one end of the impeller 51 is sealed into the groove 43, and the other end of the impeller 51 is connected to the pump body 52.

[0040] In this embodiment, by installing the pump body 52 inside the receiving cavity 45 of the drinking tray 4, the pump body 52 is isolated from the water-holding cavity 42, achieving the effect of water and electricity separation; the pump body 52 drives the impeller 51 to rotate, and the rotation of the impeller 51 causes the water in the groove 43 to gush out from the spray cover plate 6, forming a fountain effect of water splashes, so as to attract the pet to drink water.

[0041] In a preferred embodiment, the cleaning mechanism is an ultrasonic transducer 7, which is housed in the receiving cavity 45 and attached to the outer bottom surface of the water-filled cavity 42.

[0042] In this embodiment, the ultrasonic transducer 7 directly and indirectly acts on the water and dirt through the cavitation, acceleration, and direct flow effects of the generated ultrasonic waves, thereby dispersing, emulsifying, and peeling off the dirt layer to achieve the cleaning purpose. The ultrasonic transducer 7 also removes bacterial biofilms attached to the water chamber 42 and impeller 51, reducing the bacterial content in the water and ensuring the safety of the pet's drinking water.

[0043] In a preferred embodiment, the filtration mechanism 8 includes a filter seat 81 mounted on the sewage tank 3. The filter seat 81 is provided with a plurality of filter through holes 82, which communicate with the interior of the sewage tank 3. The filter seat 81 is provided with a hooking part 83 that is hooked onto the opening edge of the sewage tank 3.

[0044] In this embodiment, when the drinking tray 4 is used to pour wastewater, the wastewater is filtered through the filter holes 82 to intercept hair and dirt, preventing them from entering the sewer pipe and causing blockage. The filter base 81 is installed on the opening edge of the wastewater tank 3 via the hook part 83, which facilitates the removal of the filter base 81 and makes it easy to collect and clean any remaining hair and dirt on the filter base 81.

[0045] In a preferred embodiment, the driving mechanism includes a driving source and a rotating shaft connected to the driving source. A transmission handle 46 is provided on one side of the drinking tray 4. The transmission handle 46 is provided with a through hole that is inserted and connected to the rotating shaft. The rotating shaft is inserted and engaged with the through hole.

[0046] In this embodiment, the rotating shaft on the main unit 1 is inserted into the transmission handle 46 of the drinking tray 4. When the rotating shaft is inserted into the through hole of the transmission handle 46, and the drive source drives the rotating shaft to rotate, the transmission handle 46 can be rotated through the engagement of the rotating shaft and the through hole, thereby driving the drinking tray 4 to move. This connection method is convenient for installation and disassembly, and can also effectively transmit power.

[0047] In a preferred embodiment, the sewage tank 3 is provided with a drain outlet, which is connected to a sewer pipe. In this embodiment, by connecting the drain outlet to the sewer pipe, the sewage in the sewage tank 3 can be automatically discharged into the sewer pipe, eliminating the need for manual sewage discharge and reducing maintenance difficulty.
