Description

Technical Field

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

[0002] Pet water fountains are relatively mature products. Most of them use electricity to supply water. In order to drain wastewater in time, they are usually designed with some electric flipping structure to drain wastewater in time, such as the technical solutions described in Chinese patents with publication numbers CN118947573A, CN216796112U, CN220123671U, and CN220383950U.

[0003] However, these technological solutions heavily rely on electricity to discharge wastewater, typically through timed programs, meaning they don't actually detect whether the drinking water has been consumed. This leads to significant water waste, and the reliability of using electric motors for wastewater discharge is low due to its heavy reliance on electricity. Furthermore, given the nature of pet drinking water, there's a high probability that residue will remain and pollute the water after use.

[0004] Therefore, timely discharge of wastewater and reduction of dependence on electricity are technical problems that need to be solved. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is to provide a pet water dispenser that can discharge wastewater in a timely manner.

[0006] To achieve the above objectives, this utility model provides a pet water fountain, including a shell and a water-drinking component. The water-drinking component is provided with a rotating shaft, a water trough, and a drain hole, with the water trough and drain hole respectively located on both sides of the rotating shaft of the water-drinking component.

[0007] The rotating shaft is assembled with the outer casing, and the force on both sides of the drinking device is inconsistent so that when there is no water in the drinking tank, the position of the drain hole is lower than the drinking tank (the position where the drain hole is directly or indirectly connected to the drinking tank is lower than the drinking tank). When water is added to the drinking tank, the drinking device on one side of the drinking tank gradually rotates until the water in the drinking tank does not enter the drain hole. That is, when water is added to the drinking tank, the drinking device on one side of the drinking tank gradually rotates downward until the position of the drinking tank is lower than the drain hole (lower than the position where the drain hole is directly or indirectly connected to the drinking tank).

[0008] As a further improvement of this utility model, the drinking device is provided with a first edge and a second edge at both ends of the drinking trough and the drain hole, respectively. When the drinking device is rotated downward at the end of the drain hole, the second edge is in close contact with the top edge of the outer shell; when the drinking device is rotated downward at the end of the drinking trough, the first edge is in close contact with the top edge of the outer shell.

[0009] As a further improvement of this utility model, a counterweight is also provided or installed at one end of the drinking device located at the drain hole, and the counterweight is used to increase the weight of the drinking device at one end of the drain hole.

[0010] As a further improvement of this utility model, a buckle is provided at one end of the water drinking device located at the drain hole. The buckle engages with a buckle protrusion, which is provided on the counterweight to enable the counterweight to be installed on the water drinking device.

[0011] As a further improvement of this utility model, a water pipe is installed on the outer shell, and an impact part is provided at the drinking trough. An impact hole is provided on the impact part, and the upper part of the impact hole is directly opposite one end outlet of the water pipe. The water pipe is used to pump water in the drinking chamber to the upper part of the impact hole so that the water flow impacts the impact hole.

[0012] As a further improvement of this utility model, an impact slope is also provided on the impact part. The impact slope connects the impact hole to the drinking trough, and when the position of one end of the drain hole is lower than that of the drinking trough, the impact slope leads the water and debris in the impact hole to the drinking trough.

[0013] As a further improvement of this utility model, the interior of the outer shell is divided into a drinking water tank and a sewage tank by a partition; the drinking water trough and the drain hole are located above the drinking water tank and the sewage tank, respectively; the drinking water device at least covers or blocks the top of the drinking water tank, which can effectively protect the water in the drinking water tank and reduce the probability of external debris entering the drinking water tank.

[0014] As a further improvement of this utility model, a drinking water box and a sewage box are respectively installed in the drinking water tank and the sewage tank. The drinking water box and the sewage box are hollow and open at the top, respectively, forming a drinking water cavity and a sewage cavity. The drinking water trough and the drain hole are located above the drinking water cavity and the sewage cavity, respectively.

[0015] As a further improvement of this utility model, the other end of the water pipe is connected to one end of the connecting pipe, the other end of the connecting pipe is connected to the outlet of the water pump, and the inlet of the water pump is connected to the water in the drinking chamber; the connecting pipe is installed on the outer shell.

[0016] As a further improvement of this utility model, magnets are installed at the first edge and the second edge of the drinking device, and reed switches are installed at the corresponding positions of the outer shell and the first edge and the second edge, respectively. The reed switch signals are connected to the microcontroller, and the microcontroller controls the operation of the water pump.

[0017] As a further improvement of this utility model, the drinking device is also provided with a connecting groove, which connects the drinking trough and the drain hole. A clearance groove is provided at the end of the drinking device corresponding to the water pipe.

[0018] As a further improvement of this utility model, the outer shell is also provided with a shaft groove, which is assembled with the rotating shaft.

[0019] As a further improvement of this utility model, a pipe seat is provided on the outer shell, and an installation seat is installed inside the outer shell. The water pipe is assembled with the pipe seat, and the connecting pipe is assembled with the pipe seat and the installation seat respectively.

[0020] The beneficial effects of this utility model are:

[0021] This invention utilizes the weight difference between the two ends of the drinking device, allowing it to rotate relative to the outer casing via a pivot. This design ensures that when the water trough is full, the weight of the water keeps the trough at the bottom for easy drinking by the pet. Simultaneously, the design of the trough and impact hole allows impurities to settle, keeping the upper layer of water clean. When the water level drops to a certain point, the weight becomes insufficient to maintain the current position, causing the trough to tilt upwards, allowing the drain end to rotate downwards and expel wastewater, ensuring that subsequent water replenishment is clean. The entire process relies on gravity, requiring no electricity, resulting in a simple structure, low cost, and ease of use. Of course, electricity can be added to drive the rotation of the drinking device as needed. Furthermore, this invention uses a water pump and pipe to supply water to the trough. The impact hole inside the trough allows the water flow to directly impact the hole, using the force of the water flow to rotate the drinking device downwards at one end of the trough, thus keeping the trough full of water. This makes it very convenient to use. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] See Figures 1-10 The pet water fountain of this embodiment includes a housing 100 and a water dispenser 200. The housing 100 is divided into a water tank 102 and a wastewater tank 103 by a partition 120. The housing 100 is also provided with a shaft groove 101 and a pipe seat 110.

[0034] The drinking water tank 102 and the sewage tank 103 are respectively equipped with a drinking water box 410 and a sewage box 420. The drinking water box 410 and the sewage box 420 are respectively hollow drinking water chamber 411 and sewage chamber 421 with open tops.

[0035] The drinking device 200 is provided with a drinking trough 201, a connecting groove 202, and a drain hole 203. The connecting groove 202 connects the drinking trough 201 and the drain hole 203, and the drain hole 203 penetrates through the drinking device 200. An impact portion 220 is provided at the drinking trough 201, with an impact hole 221 and an impact ramp 222. The drinking device 200 is also provided with a handle 210 for easy lifting and rotating shafts 230 on both sides. The impact ramp 222 is more inclined when the drain hole 203 is in a low position, thus allowing water and debris to be discharged. Furthermore, the design of the impact ramp 222 ensures that the other sides of the impact hole are relatively deep, effectively receiving the impact force transmitted by the water flow and facilitating the rotation of the drinking device.

[0036] The impact part 220 and the drain hole 203 are located above the drinking water chamber 411 and the sewage chamber 421, respectively. The rotating shaft 230 is inserted into the shaft groove 101 and can be rotated relative to it. The drinking water tank 201 and the connecting groove 202 are located on both sides of the rotating shaft 230.

[0037] The impact hole 221 is directly opposite one end of the outlet of the water pipe 310. The other end of the water pipe 310 is sealed and connected to one end of the connecting pipe 320. The other end of the connecting pipe 320 is connected to the outlet of the water pump 330. The inlet of the water pump 330 is connected to the water in the drinking chamber 411. The water pipe 310 is installed on the pipe seat 110. The two ends of the connecting pipe 320 are respectively assembled with the pipe seat 110 and the mounting base 430. The mounting base 430 is installed inside the outer shell 100.

[0038] Figure 1 In the initial state, the impact part 220 is heavier at the end of the drain hole 203, causing the drain hole 203 to rotate downwards, allowing water in the drinking trough 201 and connecting trough 202 to flow into the sewage chamber 421 for storage. When water is needed, the water pump 330 is started, pumping water to the water pipe 310, and then flowing from the outlet of the water pipe 310 towards the impact hole 221. The water impacts the impact hole 221 with kinetic energy, thus breaking the balance of the drinking component 200. This causes the end of the drinking component 220 with the drinking trough 201 to rotate downwards, while the end with the drain hole 203 rotates upwards. This prevents the drain hole 203 from temporarily discharging water from the drinking trough and connecting trough. Figure 4 The water in the water trough is convenient for pets to drink. Based on the characteristics of pets' drinking habits, the water will become contaminated after drinking, but each time a pet drinks, the water level will decrease until there is not enough water in the trough to sustain them. Figure 4 In this state, under the influence of gravity, the drinking device 220 will break the balance again, causing one end of the drain hole 203 to rotate downwards and the other end of the drinking trough to rotate upwards, in order to achieve... Figure 1 The wastewater is discharged into the wastewater chamber, thus completing the wastewater discharge process. The design of the impact hole and the recessed area of ​​the drinking trough is for the purpose of facilitating water storage and also for making it easy to rotate the drinking device to the desired position when adding water. Figure 4 On the one hand, it helps to settle residue and keep the water on the surface of the drinking trough clear and clean.

[0039] When it is necessary to clean the drinking water unit 200 and the wastewater box 420 and drinking water box 410, simply lift the drinking water unit 200 upwards using the handle 210 to pull the rotating shaft 230 out of the shaft groove 101, and then remove the wastewater box 420 and drinking water box 410. It is very convenient.

[0040] In this embodiment, the operating time of the water pump can be controlled by a microcontroller, thereby controlling the amount of water pumped into the drinking trough each time the pump starts, to avoid waste. Specifically, a timer relay can be connected in series in the power supply circuit of the water pump. The control terminal of the timer relay is connected to the microcontroller for communication, thus controlling the on / off state of the water pump power supply and the on / off time each time. Of course, there are many other implementation methods in the prior art; theoretically, any method that can control the amount of water pumped into the drinking trough each time is acceptable.

[0041] In some embodiments, the drinking device 200 completely covers the drinking chamber 411 and the wastewater chamber 421, which can prevent foreign objects from entering the drinking chamber 411 and the wastewater chamber 421, thereby effectively protecting the cleanliness of the water stored in the drinking chamber 411.

[0042] In some embodiments, a clearance groove 204 is provided at the end of the drinking device 200 corresponding to the water pipe 310. The clearance groove 204 is used to prevent the drinking device 200 from directly colliding or interfering with the water pipe 310, thereby ensuring that the drinking device 200 can rotate.

[0043] The drinking device 200 is provided with a first edge 205 and a second edge 206 at both ends of the drinking trough 201 and the drain hole 203, respectively. When the drinking device 200 is rotated downwards to its final position at the end of the drain hole 203, the second edge 206 is pressed against the top edge of the outer shell 100 to achieve a limiting position. Figure 3 (State). When the drinking device 200 is rotated downwards to its designated position at one end of the drinking trough 201, the first edge 205 is pressed against the top edge of the outer casing 100 to achieve a limiting position. Figure 4 state).

[0044] In some embodiments, a counterweight 250 is also provided or installed at one end of the drinking device 200 located at the drain hole 203. The counterweight 250 is used to increase the weight of the drinking device 200 at the end located at the drain hole 203, so that the drinking device 200 is initially in a stable position. Figure 1 state.

[0045] In some embodiments, a buckle 241 is provided at one end of the drinking device 200 located at the drain hole 203. The buckle 241 engages with a buckle protrusion 242, which is disposed on a counterweight 250. The counterweight 250 is used to increase the weight of the drinking device 200 at the end located at the drain hole 203, so as to maintain the drinking device 200 in its initial state. Figure 1 Status. This design makes the counterweight 250 detachable, which reduces production costs and facilitates replacement and maintenance later.

[0046] In some embodiments, magnets can be installed at the first and second edges, and reed switches can be installed at corresponding positions on the outer casing and the first and second edges. The reed switch signals are connected to a microcontroller, allowing the status of the drinking device to be determined by the closed state of the two reed switches. This enables the water pump to be turned on promptly to supply water to the drinking tank after the drinking device discharges internal wastewater, thus achieving automatic water supply. In use, it is only necessary to detect which reed switch is closed and which is open to determine the status, as the closed reed switch indicates that the corresponding end of the drinking device is at the bottom.

[0047] In some embodiments, instead of using the gravity difference between the two sides of the drinking device 200 to achieve rotation, electric power is used to drive the rotation of the drinking device 200. For example, a motor can be installed at the rotating shaft, and the motor drives the rotating shaft to rotate; or the motor drives the rotating shaft 230 to rotate through a transmission structure, such as a gear shaft, worm gear, or belt drive. Theoretically, the motor ultimately drives the rotating shaft to rotate, thus driving the drinking device to rotate; or a structure that drives the drinking device 200 to rotate up and down can be installed on both sides / one side of the displacement rotating shaft 230 of the drinking device 200, such as an electromagnet or electric cylinder, to drive the drinking device 200 to rotate around the rotating shaft. Of course, these are all existing technologies, and those skilled in the art can implement them using existing technologies. Theoretically, as long as the alternating up and down rotation of the two ends of the drinking device 200 can be achieved, there are obviously countless ways to achieve this in the existing technology.

[0048] In this embodiment, to achieve inconsistent force distribution at both ends of the drinking device 200 around the pivot, it is not only possible to use the counterweight 250, but also through any of the following methods or combinations thereof:

[0049] 1. Install springs or elastic components (such as elastic ropes, elastic bands, etc.) at one or both ends of the drinking device 200 to make the force on both sides of the device uneven.

[0050] 2. Install magnets or electromagnetic coils at one or both ends of the drinking device 200 to achieve inconsistent forces on both sides by utilizing the principle of like poles repelling and unlike poles attracting.

[0051] 3. Remove counterweight 250 and use more material for the corresponding drinking water component 200 to increase its weight, causing uneven force distribution on both sides.

[0052] 4. A fluid jetting device is installed at one or both ends of the drinking device 200 to achieve uneven force at both ends through the thrust of the fluid. For example, a nozzle is installed on the drinking device 200 below the drinking trough 201. The nozzle sprays water or air downwards from the drinking device 200 to give this end of the drinking device 200 an upward rotational thrust.

[0053] Of course, in actual implementation, it is only necessary to make one end of the drinking device tilt up due to uneven or inconsistent force on both ends, and it is not limited to the above solution.
