Abstract
Description
Technical Field
[0001] This utility model relates to the field of pet feeding equipment technology, and in particular to a pet water feeder. Background Technology
[0002] Existing pet water dispensers, especially those designed for small pet environments such as birdcages, typically use an inverted water bottle or a simple water bowl. These dispensers generally have the following problems: First, the water remains stagnant for extended periods, making it easy for bacteria to grow; second, food scraps, feathers, feces, and other contaminants from pets easily fall into the water, seriously polluting the water source and posing a threat to the pet's health. Therefore, pet owners need to frequently check, change the water, and clean the dispensers, which is very inconvenient for busy pet owners or those who are away for short periods.
[0003] Furthermore, some water dispensers do not separate clean and dirty water, using a whole-system circulation and filtration system to provide pets with drinking water instead of providing a fresh source of clean water. This results in pets drinking not fresh, clean water, but rather stored, unclean, second-filtered water, thus raising concerns about contamination in their drinking water. Utility Model Content

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0022] This embodiment provides a pet water dispenser, such as Figures 1-6 As shown, the system includes a clean water storage tank 1, a wastewater collection tank 2, a water dish 3, a water supply device 6, and a drainage device 7. The clean water storage tank 1 is used to store clean drinking water; the water dish 3 is used to provide a direct drinking area for pets; and the wastewater collection tank 2 is used to collect wastewater discharged from the water dish 3.
[0023] The clean water storage tank 1 is located on the upper part of the device. Its main body can be integrally molded from food-grade polypropylene plastic using an injection molding process, possessing both good chemical stability and durability. The volume of the clean water storage tank 1 can be designed from 1 liter to 3 liters, for example, 1.5 liters in this embodiment, which is sufficient to meet the drinking water needs of a small pet for several days. The top of the clean water storage tank 1 is equipped with a removable water tank cover 11. The water tank cover 11 is tightly fitted to the opening edge of the clean water storage tank 1 by a threaded or snap-fit structure. This design not only prevents dust and other impurities from falling into the clean water storage tank 1 and contaminating the water source, but also facilitates users to add water and regularly clean the interior of the clean water storage tank 1.
[0024] A clean water storage tank 1 is positioned directly above a wastewater collection tank 2. A drinking tray 3 is vertically positioned between the clean water storage tank 1 and the wastewater collection tank 2, extending to one side. A water supply device 6 is located between the clean water storage tank 1 and the wastewater collection tank 2, capable of supplying water from the clean water storage tank 1 to the drinking tray 3. A drainage device 7 is located below the drinking tray 3, used to drain water from the drinking tray 3 into the wastewater collection tank 2. This water dispenser employs a layered design in its physical structure to effectively isolate clean water, drinking water, and wastewater.
[0025] In this embodiment, by setting up independent clean water storage tank 1, wastewater collection tank 2 and drinking tray 3, the water change logic of "draining first and then refilling" can be realized. This can completely replace the old water in the drinking tray 3, ensuring that the pet can drink fresh and clean water every time. This fundamentally avoids the problem of pollutant accumulation in the circulating filtration system and effectively protects the pet's drinking water health.
[0026] In one preferred embodiment, the bottom of the clean water storage tank 1 is provided with a water outlet 12, and the drinking tray 3 is provided with a water inlet 31. The water supply device 6 includes a solenoid valve 61 and a water supply pipe 62. The solenoid valve 61 is installed at the water outlet 12, and the water outlet 12 is connected to the water inlet 31 through the water supply pipe 62. The water supply pipe 62 can be a flexible silicone pipe.
[0027] The bottom outlet 12 of the clean water storage tank 1 is directly connected to the drinking tray 3 via a water supply pipe 62, and a normally closed solenoid valve, acting as a water supply valve, is installed on this connecting pipe. It should be noted that for the system to function properly, a key structural requirement is that the overall installation position of the clean water storage tank 1 must be significantly higher than that of the drinking tray 3, thereby creating a sufficient water level difference between the two to generate gravitational potential energy. This eliminates the need for a water pump and its related components, reducing manufacturing costs and potential failure points, thus improving the long-term reliability of the system.
[0028] In a preferred embodiment, the water supply device 6 further includes a water supply pump 63, which is connected to the water supply pipe 62. The inlet of the water supply pump 63 is connected to the clean water storage tank 1, and its outlet is connected to the drinking tray 3. The water supply pump 63 further improves the reliability of the clean water storage tank 1 supplying water to the drinking tray 3, and the rate at which the clean water storage tank 1 supplies water to the drinking tray 3 can be adjusted by the water supply pump 63.
[0029] In a preferred embodiment, to further maintain the cleanliness of the water in the water dish 3 during the interval between water changes, this embodiment also includes a water dish cover 4. The water dish cover 4 covers the water dish 3, and a drinking spout 41 for the pet to drink is provided on the side of the water dish cover 4 facing away from the clean water storage tank 1. The water dish cover 4 can be made of the same plastic material as the outer shell, and its structure is designed to cover the opening of the water dish 3 over a large area, with one or more appropriately sized drinking spouts 41 only on the edge or in specific locations. The size of these drinking spouts 41 is designed to be just large enough for the pet (such as a bird) to put its head in to drink, but to effectively block large particulate contaminants such as feces, feathers, and food scraps falling from above, thus playing an important physical protective role. The water dish cover also prevents water from splashing out of the water bowl when the pet drinks. In addition, the water dish cover 4 can also be made of transparent material to facilitate observation of the pet's drinking status.
[0030] In a preferred embodiment, a drain outlet 32 is provided at the bottom of the drinking tray 3, and a drain pipe 9 is provided below the drain outlet 32. The bottom end of the drain pipe 9 is connected to the sewage collection tank 2. A drainage device 7 is provided at the drain pipe 9 below the drain outlet 32 and can connect or disconnect the drain outlet 32 and the drain pipe 9. Preferably, a drainage chamber 91 is provided on the drain pipe 9 directly below the drain outlet 32, and the drainage device 7 is provided at the drainage chamber 91. When the drainage device 7 is opened, the drain outlet 32 and the drainage chamber 91 are connected. Preferably, an overflow hole 33 is provided on the upper edge of the drinking tray 3. The overflow hole 33 is connected to the drain pipe 9 through an overflow pipe 92 so that the drain pipe 9 can collect water overflowing from the drinking tray 3.
[0031] In one preferred embodiment, the water dish 3 is cone-shaped, with a drain outlet 32 located at the bottom of the cone and a water inlet 31 located on the side wall of the cone. The shape of the water dish 3 facilitates water storage and drainage, while also meeting the pet's drinking needs.
[0032] To ensure pet safety and ease of cleaning, the water dish 3 is preferably made of 304 stainless steel using a stamping process. Its smooth surface makes it resistant to dirt and bacteria buildup, and it is easy to clean. The water dish 3 is designed as a shallow dish with rounded edges and a moderate depth (e.g., 2-3 cm), which can hold enough water for one drinking session while preventing accidents to smaller pets (such as birds).
[0033] As a preferred embodiment, such as Figure 6 As shown, the drainage device 7 includes a drive assembly 71, a connecting plate 74, a sealing plate 76, and an elastic element 73. The connecting plate 74 is connected to the output shaft 72 of the drive assembly 71. The drive assembly 71 consists of a motor and a reducer. An abutment plate 75, perpendicular to the connecting plate 74, is provided at one end of the connecting plate 74 away from the output shaft 72. The sealing plate 76 is connected to the connecting plate 74. The elastic element 73 is sleeved on the output shaft 72, with one end abutting against the abutment plate 75 and the other end abutting against the bottom of the drinking tray 3. The elastic element 73 is a spring.
[0034] Before adding new water to the drinking tray 3, the water in the drinking tray 3 is first drained into the wastewater collection tank 2. Under normal conditions, the sealing plate 76, under the action of the elastic element 73, abuts against the lower side of the drain outlet 32 to seal the drain outlet 32. When it is necessary to drain the water from the drinking tray 3, the drive assembly 71 drives the connecting plate 74 to rotate, compressing the elastic element 73 and causing the sealing plate 76 to open the drain outlet 32, thereby emptying the water in the drinking tray 3. After emptying, the sealing plate 76, under the action of the elastic element 73, abuts against the lower side of the drain outlet 32 again to seal the drain outlet 32.
[0035] Wastewater collection tank 2 is used to collect all wastewater and pollutants discharged from drain outlet 32. Wastewater collection tank 2 can be designed as a drawer-type structure with a handle 21 for easy periodic emptying and cleaning. Its volume is typically designed to be slightly larger than that of clean water storage tank 1, for example, 2 liters, to ensure sufficient space to hold all discharged wastewater before clean water storage tank 1 is depleted, preventing overflow. It should be noted that this three-layer structure of clean water storage tank 1, drinking tray 3, and wastewater collection tank 2, arranged from top to bottom, utilizes gravity to naturally achieve physical separation of clean and wastewater, fundamentally eliminating the possibility of cross-contamination.
[0036] In a preferred embodiment, this embodiment also includes a control unit. A liquid level sensor 81 is provided in the drinking tray 3. The control unit is electrically connected to the water supply device 6, the drainage device 7 and the liquid level sensor 81.
[0037] In this embodiment, the liquid level sensor 81 is specifically a contact-type electrode water level sensor, consisting of two stainless steel probes with a fixed distance between them. The height of these two probes corresponds to the preset maximum safe water level. When the water level is below this height, there is air between the two probes, and the circuit is open. When the water level rises and simultaneously submerges the two probes, the water acts as a conductor, forming a weak conductive loop between the two probes, thereby triggering a change in a voltage level signal.
[0038] To achieve intelligent monitoring of the remaining water level in the clean water storage tank 1, a water level sensor is installed near the bottom of the outer wall of the clean water storage tank 1. In this embodiment, the water level sensor is specifically a Hall effect sensor, which works in conjunction with a float (not shown) with a built-in magnet. The float is placed inside the clean water storage tank 1 and has a density less than water, so it can float up and down with changes in water level. When the clean water storage tank 1 has sufficient water, the float is at a higher position, and its built-in magnet is away from the Hall effect sensor; when the water level drops to a preset minimum threshold (e.g., 10% water remaining), the float drops to the bottom of the tank, causing the magnet to approach the Hall effect sensor, resulting in a significant change in the magnetic field strength detected by the sensor, thereby generating a water shortage signal.
[0039] By installing a liquid level sensor in the drinking tray 3, precise control of the water volume is achieved, avoiding problems of water overflow or insufficient volume and improving the reliability of equipment operation.
[0040] In a preferred embodiment, the clean water storage tank 1 is positioned directly above the wastewater collection tank 2. A central cavity 51 is formed within the housing 5 between the clean water storage tank 1 and the wastewater collection tank 2. The control unit, water supply device 6, and drainage device 7 are all housed within the central cavity 51. The drinking tray 3 is arranged side-by-side on one side of the central cavity 51. The circuit board 82 of the control unit is mounted on the side of the central cavity 51 away from the water supply pump.
[0041] The pet water dispenser implemented in this way is a single unit, which is easy to use and install, and has a compact layout that takes up little space.
[0042] In one preferred embodiment, the control unit includes a wireless communication module, which sends a water shortage reminder signal to the user terminal.
[0043] In addition, a user interface can be installed on the device casing, such as a fixed knob with a multi-functional display. Users can perform local operations by rotating or pressing this knob, such as manually triggering water changes or setting timed water change intervals. Correspondingly, the display screen can show the device's operating status in real time, such as the current time, the next water change time, and whether water is low. By integrating intelligent modules such as water volume sensing, remote communication, and water quality monitoring, the system achieves automated and intelligent management of the water feeder. Users can remotely monitor and control it, and change the water as needed, greatly improving the convenience of feeding and reducing the burden of manual maintenance.
[0044] Users can remotely set the frequency of water feeding / water removal via a mobile app, ensuring that pets won't be unable to drink water when they are not at home or forget, and saving users the trouble of frequently changing water and cleaning water bowls.
[0045] The entire automated function of the water feeder is coordinated and executed by a microcontroller, which serves as the core of the control unit. This microcontroller can be a commonly available low-power single-chip microcomputer. The power module is responsible for converting the external AC power input or the DC power from the internal battery into the different voltages required by the various components of the system, providing a stable power supply to all electronic components such as the microcontroller, water pump, solenoid valve, level sensor, water volume sensor, wireless communication module, and user interface. The microcontroller is electrically connected to each sensor and actuator through its input / output pins. Specifically, the microcontroller receives water level up / down signals from the level sensor and water shortage signals from the water volume sensor. It also interacts with the user's smart terminal (such as a mobile application) through the wireless communication module. In this embodiment, the wireless communication module can be a Wi-Fi module, enabling the water feeder to connect to the home wireless network. The user can then remotely check the device status, receive water shortage reminders, and send remote water change commands at any time through the mobile application.
[0046] In this embodiment, before adding clean water each time, the drain outlet is opened to drain the water from the drinking dish into the wastewater tank; after the wastewater is drained, the drain outlet is closed; the water pump then pumps clean drinking water from the clean water storage tank into the drinking bowl. Water supply stops when the water level reaches the water level sensor position; when the water level in the clean water storage tank reaches near the bottom, the Hall effect switch receives a signal and issues a water shortage notification. By integrating intelligent modules such as water level sensing, remote communication, and water quality monitoring, the water feeder achieves automated and intelligent management. Users can remotely monitor and control it, and change the water as needed, greatly improving the convenience of pet ownership and reducing the burden of manual maintenance.
[0047] Through the aforementioned structure and workflow, this embodiment achieves fully automatic and timed hygienic water changes, ensuring that pets can always drink fresh, clean water. Meanwhile, the design of the water tray cover 4 effectively prevents secondary contamination of the water source by external pollutants, while the intelligent water shortage reminder function significantly improves the convenience and reliability of use.
[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
