Description

Technical Field

[0001] This invention relates to the field of water dispenser technology, and more particularly to a pet water dispenser. Background Technology

[0002] Most pet water fountains on the market today only offer simple water filtration and water recycling; few have features that separate wastewater from clean water to prevent bacterial growth from repeated use, or offer intelligent and convenient water storage and dispensing functions.

[0003] Existing pet water fountains with automatic tipping and water-pouring functions typically use a motor to directly drive the tipping and resetting process. During this process, the motor rotor often generates resistance, resulting in uneven tipping, increased energy consumption, and long-term use can easily cause excessive motor load. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a pet water fountain.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A pet water fountain, including a water stand, and further comprising:

[0007] A water basin is rotatably connected to the water stand.

[0008] The flipping component, located inside the water dispenser, includes a driving device, a first transmission component, and a second transmission component nested outside the first transmission component. The outer surfaces of the first and second transmission components are both cylindrical structures and can be rotatably connected to the water dispenser. The first and second transmission components rotate coaxially. The first transmission component is driven by the driving device, and the second transmission component is driven by the water basin.

[0009] It also includes a first guide groove disposed on the outer surface of the first transmission member and a second guide groove disposed on the outer surface of the second transmission member, the first guide groove including a first driving section and the second guide groove including a second driving section; and

[0010] A guiding device having a guiding protrusion that passes through the second driving section and is inserted into the first guide groove;

[0011] When the driving device drives the first transmission component to rotate, the first driving segment will push the guide device to move from one end of the first transmission component to the other end. At the same time, the guide device will push the second driving segment and the second transmission component to rotate, and the rotation of the second transmission component will drive the drinking basin to rotate.

[0012] Furthermore, the center of gravity of the drinking basin is offset from its rotation axis, and the first guide groove includes a separation section extending axially along the first transmission member and a first drive section arranged circumferentially. The separation section and the first drive section are connected end to end to form a curved closed-loop structure surrounding the outer surface of the first transmission member.

[0013] Furthermore, when the driving device stops moving, the drinking basin flips over under its own weight and drives the second transmission component to rotate in the forward direction. The second driving section on the second transmission component will push the guide device to slide along the separation section. During this process, the drinking basin will pour out the wastewater that has been consumed.

[0014] Furthermore, the first drive section includes a first groove section and a second groove section. The first groove section is an arc segment circumferentially arranged in the first transmission component, and its cross section is perpendicular to the axial direction of the first transmission component. The second groove section spirals around the transmission shaft circumferentially and connects the first groove section and the separation section.

[0015] Furthermore, one end of the second transmission component is provided with a transmission gear, which is connected to the drinking basin in a transmission manner.

[0016] Furthermore, the flipping assembly also includes a limiting housing, the first transmission member and the second transmission member are installed in the limiting housing, the inner side of the limiting housing is provided with a sliding groove along its axial direction, and the guide device is reciprocally disposed in the sliding groove.

[0017] Furthermore, the guide device is equipped with a magnetic component, and the slide is provided with a position detection element that cooperates with the magnetic component. The position detection element is used to detect the position information of the guide device.

[0018] Furthermore, a quick-release assembly is installed on the rotating end of the drinking basin. The quick-release assembly includes a transmission connection part, a one-way locking part, and an operating component. The transmission connection part is fixedly installed on the rotating end of the drinking basin. The one-way locking part is detachably engaged with the transmission connection part to transmit the power of the flipping assembly and restrict the reverse rotation of the drinking basin. The operating component is rotatably connected to the one-way locking part. By operating the operating component, the one-way locking part can be separated from the transmission connection part, thereby realizing the quick assembly and disassembly of the drinking basin and the flipping assembly.

[0019] Furthermore, the operating component is installed between the water dispenser and the water basin. The water dispenser has an installation hole, and a limiting hole is provided inside the installation hole. The operating component has a limiting protrusion that adapts to the limiting hole. The operating component is fixed by passing through the limiting hole and rotating through the limiting protrusion.

[0020] Furthermore, the drinking basin is provided with a counterweight and a liquid level detection element. The counterweight is located at the downward rotating end of the drinking basin, and the liquid level detection element is covered with a protective sleeve. It also includes a control device, which is electrically connected to the drive device, the position detection element and the liquid level detection element, respectively, and is used to control the start and stop of the drive device according to the position information of the position detection element or the liquid level information of the liquid level detection element.

[0021] The beneficial effects of this invention are:

[0022] 1. The pet water fountain proposed in this invention improves efficiency and reliability through structural design: the motor does not need to change direction during operation, and only needs to rotate in one direction, which reduces energy loss and mechanical wear. Therefore, the transmission efficiency is higher, the operation is more stable and reliable, and the motor life can be extended. The manufacturing process of the unidirectional rotating motor is simpler and the cost is lower.

[0023] 2. The pet water fountain proposed in this invention uses a unique circumferential extension structure in the first trough section to stably restrict the guiding device within the trough section, thereby reliably locking the second transmission component and keeping it fixed, achieving self-locking. At this time, an appropriate amount of clean water is injected into the water bowl to provide a stable horizontal drinking interface for the pet.

[0024] 3. The pet water fountain proposed in this invention achieves automatic switching of movement modes during the entire flipping process by setting a flipping component. During the self-weight flipping stage, the guide device moves smoothly along the axial direction without driving the motor. During the motor drive stage, a stable rotational driving force is provided through the circumferential groove section. This not only realizes the automatic disengagement of the drive device and the water bowl, but also significantly reduces energy loss. At the same time, it ensures a smooth and shock-free movement process, greatly improving the service life and operational reliability of the equipment.

[0025] 4. The pet water dispenser proposed in this invention, by setting a second transmission component and a transmission shaft, and setting a guide window on the second transmission component that matches the inclination angle of the spiral groove of the transmission shaft, ensures that the motion trajectory of the guide device remains highly consistent in both gravity-fed and motor-driven working modes, effectively avoiding motion interference and jamming. The second drive section not only plays the role of transmitting torque, but also realizes precise control of the motion trajectory, which significantly improves the coordination and reliability of the entire transmission system.

[0026] 5. The pet water dispenser proposed in this invention provides a stable support base and guiding benchmark for the guiding device by setting a limiting shell, which ensures the positioning of the guiding device during complex movements, effectively reduces the wear of individual components, and improves the stability of the system.

[0027] 6. The pet water fountain proposed in this invention achieves quick separation and connection between the water bowl and the water stand by setting up a quick-release component. The one-way locking part ensures the transmission reliability during normal operation and prevents accidental reverse rotation. This not only simplifies the maintenance process but also improves the ease of use of the equipment, allowing users to easily disassemble and install the water bowl, greatly enhancing the practicality of the product and the user experience.

Detailed Implementation

[0051] The following is combined with Figures 1-21 The present invention will be described in detail below.

[0052] A pet water fountain includes a water stand 10, and also includes:

[0053] The water basin 20 is rotatably connected to the water stand 10, and the center of gravity of the water basin 20 is off-center from its axis of rotation.

[0054] The flipping assembly, located within the water dispenser 10, includes a drive device 307, a first transmission member 301, a second transmission member 302 nested outside the first transmission member 301, and a limiting housing 304. The limiting housing 304 is fixed to the water dispenser 10. The outer surfaces of both the first transmission member 301 and the second transmission member 302 are cylindrical structures and can be rotatably connected within the limiting housing 304. Their rotation axes are coaxial, allowing them to be installed within the water dispenser 10 and rotate coaxially. The first transmission member 301 is driven by the drive device 307 and rotates accordingly. The second transmission member 302 is driven by the water basin 20. It is understood that the limiting housing 304 can be omitted; simply placing the first transmission member 301 and the second transmission member 302 on the water dispenser is sufficient.

[0055] It also includes a first guide groove disposed on the outer surface of the first transmission member 301 and a second guide groove disposed on the outer surface of the second transmission member 302. The first guide groove includes a separation section 3011 extending axially along the first transmission member 301 and a first driving section arranged circumferentially around it. The separation section 3011 and the first driving section are connected end-to-end to form a curved closed-loop structure surrounding the outer surface of the first transmission member 301. The second guide groove includes an arc-shaped second driving section 3021 extending circumferentially along the outer surface of the second transmission member 302; and

[0056] A guide device 303 is provided, with its first side slidably connected to the water dispenser 10 and its second side fixedly provided with a guide protrusion 3031. The guide protrusion 3031 passes through the second drive section 3021 and is inserted into the first guide groove.

[0057] The inner side of the limiting housing 304 is provided with a sliding groove 3041 along its axial direction. The guide device 303 is reciprocally slidably disposed in the sliding groove 3041. The sliding groove 3041 is used to prevent the guide device 303 from deflecting when it is pushed by the first transmission member 301 or the second transmission member 302.

[0058] In this embodiment, as Figure 11 As shown, the end of the second transmission member 302 furthest from the drive device 307 is provided with a transmission gear 3022, which is connected to the rotating shaft of the drinking basin 20 via a transmission belt or gear set. Thus, when the second transmission member 302 rotates, it can drive the drinking basin 20 to rotate via the transmission gear 3022. When the drinking basin 20 rotates under its own weight, it can also drive the second transmission member 302 to rotate.

[0059] During operation, after the pet finishes drinking from the water bowl 20, the drive device 307 rotates the first transmission member 301 until one end of the separating section 3011 contacts the guide device 303. Then, the drive device 307 stops rotating, bringing the first transmission member 301 to a standstill. Next, the water bowl 20 flips under its own weight, causing the second transmission member 302 to rotate forward. The second drive section 3021 on the second transmission member 302 pushes the guide device 303 to slide along the separating section 3011, moving it from near the transmission gear 3022 to away from it. During this process, the water bowl 20 emptys the water it has consumed. Next, the guide device 303 enters the first drive section from the separating section 3011. The drive device 307 then drives the first transmission member 301 to rotate. Since the separating section 3011 and the first drive section are connected end-to-end and surround the outer surface of the first transmission member 301, the first drive section will push the guide device 303 from a position away from the transmission gear 3022 to a position closer to the transmission gear 3022. During this process, because the guide device 303 passes through the second drive section 3021, it pushes the second drive section 3021 and the second transmission member 302 to rotate in the opposite direction. The reverse rotation of the second transmission member 302 will drive the drinking basin 20 to rotate and reset via the transmission gear 3022. After resetting, the drinking basin 20 can continue to receive clean drinking water.

[0060] It is understandable that the first transmission member 301 does not necessarily need to be provided with a separation section 3011. As long as the first drive section can push the guide device 303 to move from one end of the first transmission member 301 to the other end, the movement of the guide device 303 will synchronously drive the second drive section 3021 and the second transmission member 302 to rotate, thereby achieving the purpose of controlling the rotation of the drinking basin 20 through the drive device 307.

[0061] To ensure the drinking basin 20 remains stationary when filled with water, the first drive section includes a first groove section 3012 and a second groove section 3013. The first groove section 3012 is a circumferentially arranged arc segment of the first transmission member 301, and its cross-section is perpendicular to the axial direction of the first transmission member 301. Thus, when the guide device 303 operates within the first groove section 3012, the second transmission member 302 remains stationary, thereby keeping the drinking basin 20 stationary. The second groove section 3013 spirally surrounds the drive shaft circumferentially and connects the first groove section 3012 and the separation section 3011.

[0062] Specifically, the first guide groove consists of three continuous and smoothly transitioning grooves: the separation section 3011 is a straight groove extending axially, the first groove section 3012 is an annular groove extending circumferentially, and the second groove section 3013 is a spiral groove connecting the two. The straight groove section ensures that the guide device 303 can move smoothly axially during its own weight flipping process, the annular groove section provides a stable rotational driving force during the motor drive reset phase, and the spiral transition groove section realizes the natural conversion between motion modes, avoiding motion interference and impact.

[0063] The first groove segment 3012 plays a positioning and locking role in the cooperation between the first transmission member 301 and the second transmission member 302. When the guide device 303 moves into the range of the first groove segment 3012 under the drive of the drive device 307, the circumferential extension structure can effectively restrict the axial degree of freedom of the second transmission member 302. At the same time, the guide device 303 generates sufficient friction through the tight cooperation with the groove wall, thereby stably holding the second transmission member 302 at a predetermined angle position, ensuring that the water bowl 20 can always maintain a horizontal posture when not tipped over, providing a stable drinking interface for the pet.

[0064] In this embodiment, as Figure 11 As shown, the second transmission member 302 is nested outside the first transmission member 301. The second drive section 3021 includes a first limiting position and a second limiting position that are offset from each other in the circumferential direction and the axial direction. A guide window is connected between the first limiting position and the second limiting position. The inclination angle of the second groove section 3013 is the same as the inclination angle of the guide window of the second transmission member 302.

[0065] The second transmission component 302 adopts a cylindrical structure. The second transmission component 302 is sleeved outside the first transmission component 301 and maintains an appropriate gap. The side wall of the second transmission component 302 has a specially shaped guide window, which extends in both the axial and circumferential dimensions to form a specific tilt angle. This angle matches the tilt angle of the spiral transition groove section on the surface of the first transmission component 301. This matching relationship ensures that the movement trajectory of the guide device 303 between the second transmission component 302 and the first transmission component 301 is completely synchronized, realizing the accuracy of power transmission and the smoothness of motion conversion.

[0066] In this embodiment, as Figure 7-10 As shown, the guide device 303 is equipped with a magnetic component 305, and the slide groove 3041 is provided with a position detection element 306 that cooperates with the magnetic component 305. The position detection element 306 is used to detect the position information of the guide device 303.

[0067] The guide device 303 is embedded with permanent magnet material, and magnetic sensing elements are fixedly installed next to the guide rail of the limiting housing 304. These sensing elements can sense the positional changes of the permanent magnet material, thereby accurately detecting the axial position of the guide device 303. The detection signal is transmitted to the control system to provide a basis for judging the working status of the pet water fountain and ensure the accurate execution of the automatic control process.

[0068] In this embodiment, as Figure 5 As shown, a quick-release assembly is installed on the rotating end of the drinking basin 20. The quick-release assembly includes a transmission connection part 401, a one-way locking part 402, and an operating member 403. The transmission connection part 401 is fixedly installed on the rotating end of the drinking basin 20. The one-way locking part 402 is detachably engaged with the transmission connection part 401 to transmit the power of the flipping assembly and restrict the reverse rotation of the drinking basin 20. The operating member 403 is rotatably connected to the one-way locking part 402. By operating the operating member 403, the one-way locking part 402 can be separated from the transmission connection part 401, thereby realizing the quick assembly and disassembly of the drinking basin 20 and the flipping assembly.

[0069] The quick-release assembly includes: a transmission connection part 401, which is a gear sleeve fixed on the transmission interface of the water basin 20 shaft; a one-way locking part 402, which is a one-way damping gear with one-way anti-reverse function; and an unlocking screw pin that is easy to operate manually. The gear sleeve and the one-way damping gear adopt a separable plug-in method. During normal operation, it can reliably transmit torque and prevent reverse rotation. By operating the unlocking screw pin, the gear sleeve can be disengaged from the one-way damping gear, thereby realizing the quick separation of the water basin 20 from the drive system, which greatly facilitates daily cleaning and maintenance operations.

[0070] In this embodiment, as Figure 4-5 As shown, the operating component 403 is installed between the water dispenser 10 and the water basin 20. The water dispenser 10 is provided with an installation hole 101 and a limiting hole 102 is provided inside the installation hole 101. The operating component 403 is provided with a limiting protrusion 4031 that is adapted to the limiting hole 102. The operating component 403 is fixed by passing through the limiting hole 102 through the limiting protrusion 4031 and rotating.

[0071] Specifically, the operating component 403 is an unlocking screw pin. The unlocking screw pin and the water dispenser 10 are connected by a rotating snap-fit ​​structure. The water dispenser 10 has a specially shaped installation opening. The unlocking screw pin is correspondingly provided with a matching limiting protrusion 4031. By aligning the limiting protrusion 4031 with the installation opening and inserting it and rotating it at a specific angle, the unlocking screw pin can be securely installed. Reverse rotation allows for quick disassembly. This connection method not only ensures the reliability of the working state but also greatly simplifies the disassembly and assembly process.

[0072] In this embodiment, as Figure 6As shown, the drinking basin 20 is equipped with a counterweight 201 and a liquid level detection element 202. The counterweight 201 is located at the end of the drinking basin 20 that rotates downwards, and the liquid level detection element 202 is covered with a protective sleeve.

[0073] The counterweight 201 is located at the lower end of the drinking basin 20 when it is flipped, and is used to provide a stable flipping torque. At the same time, a liquid level detection element 202 is installed on the inner wall of the drinking basin 20. The liquid level detection element 202 is wrapped with a protective cover. The protective cover is made of a material with good light transmittance and corrosion resistance, which can protect the sensor from damage without affecting its detection accuracy, ensuring accurate monitoring of drinking water volume and timely triggering of water replenishment action.

[0074] In this embodiment, a control device 70 is also included. The control device 70 is electrically connected to the drive device 307, the position detection element 306, and the liquid level detection element 202, respectively, and is used to control the start and stop of the drive device 307 according to the position information of the position detection element 306 or the liquid level information of the liquid level detection element 202.

[0075] The control device 70 is the main control board, and the drive device 307 is a unidirectional motor. The main control board establishes signal communication with the unidirectional motor, the position detection element 306, and the liquid level detection element 202 through electrical connection. The control system can determine the status of the drinking basin 20 based on the position signal, or determine the timing of water replenishment based on the liquid level signal, and then control the operation of the drive motor. The system has multiple preset working modes, including periodic flipping mode, on-demand water replenishment mode, and manual control mode. It also has a safety protection function, which can automatically stop operation and issue a warning signal when an abnormal situation is detected.

[0076] The water dispenser 10 and the clean water tank 60 and the wastewater tank 50 are respectively located on the front and rear sides of the water dispenser 10. The wastewater tank 50 is detachably mounted on the water dispenser 10. The wastewater tank 50 is equipped with a wastewater cover 501. The upper surface of the wastewater cover 501 is grooved and has a drain hole for draining wastewater.

[0077] The present invention provides a pet water fountain, the method of which is as follows:

[0078] Upon first use, install the water basin 20 into the flip space of the water holder 10 using the quick-release assembly, ensuring that the transmission connection 401 and the one-way locking part 402 are reliably engaged. Inject an appropriate amount of water into the water basin 20 through the water filling mechanism and connect the power supply.

[0079] Upon receiving a high water level signal from the liquid level detection element 202, the control device 70 initiates an automatic workflow.

[0080] First, such as Figure 16-18As shown, when the wastewater is poured out, the drive device 307 remains de-energized and the guide mechanism is in a disengaged state; the drinking basin 20 begins to slowly rotate under its own weight under the action of the counterweight 201, pouring out the wastewater in the drinking basin 20; during the pouring process, the guide device 303 moves smoothly along the separation section 3011, the first transmission component 301 and the second transmission component 302 maintain relative rotation, and there is no motor resistance during the rotation process;

[0081] Next, as Figure 19-21 As shown, after the wastewater is poured out, the position sensing element detects that the guide device 303 has reached the second position. The control device 70 immediately starts the drive device 307, which drives the guide device 303 to move along the first drive section and the second groove section 3013 through the rotation of the first transmission member 301, and drives the second transmission member 302 to rotate synchronously, so that the water bowl 20 is reset to a horizontal state. During the reset process of the water bowl 20, the guide device 303 will move along the second groove section 3013 and eventually enter the first groove section 3012 that extends horizontally in the circumferential direction of the first transmission member 301. At this time, the first groove section 3012, through its unique circumferential extension structure, stably restricts the guide device 303 within the groove section, thereby reliably locking the second transmission member 302 and keeping it fixed. Then, an appropriate amount of clean water is injected into the water bowl 20 to provide a stable horizontal drinking interface for the pet.

[0082] Finally, when the wastewater is poured out again, the drive device 307 is started again, so that the guide device 303 leaves the circumferential extension structure of the first tank section 3012. After the guide device 303 enters the separation section 3011, the drive device 307 is turned off; the drinking basin 20 is used to pour out the wastewater, and the process is repeated.

[0083] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand and implement the present invention. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
