Technical Field

[0001] This utility model relates to the field of silent control technology for pet water fountains, specifically a device for suppressing the operating noise of a pet water fountain. Background Technology

[0002] Pet water fountains are used in bedrooms at night. Current pet water fountains mainly rely on the quiet control of the water pump, but lack noise suppression technology for the water channel and water flow. As a result, the operating noise of mainstream pet water fountains is generally above 20 decibels in laboratory tests, which can affect the sleep of both humans and pets in the bedroom at night. To address this, we provide a device for suppressing the operating noise of pet water fountains. Utility Model Content

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-3A device for suppressing the operating noise of a pet water fountain includes a water tank 5 and a water pump 16. The water pump 16 is installed inside the water tank 5, which stores water to provide a continuous water supply to the pump 16. The pump 16 powers the water flow, delivering the water from the water tank 5 to a silicone hose 4, creating a fountain-like water flow. The outlet of the pump 16 is connected to the silicone hose 4. A filter disc 3 is fitted to the top of the water tank 5 and is snapped into place, simultaneously securing filter cotton 2. Filter cotton 2 is installed inside the filter disc 3, filtering the water flowing in from the water receiving tray 1 and intercepting pollutants such as hair and impurities. The top of the filter disc 3 is snapped into the water receiving tray 1, and the bottom of the filter disc 3 is connected to the silicone hose 4 via a pipe. The top of the water receiving tray 1 has a water inlet that communicates with the filter disc 3, receiving the water flowing out of the silicone hose 4 to create a stable drinking area for pets. The water dispenser uses a silicone hose 4 to provide a buffer space for the spring-like water flow, preventing water from dripping directly onto the water tank 5 and causing impact noise. It also controls the water flow range, reducing additional noise caused by turbulence. One end of the silicone hose 4 connects to the outlet of the water pump 16, and the other end extends to a corresponding position to form a spring-like water outlet, delivering water from the water tank 5. The silicone material of the hose 4 has excellent sealing performance, preventing dripping noise caused by water leakage. Its soft and adjustable material allows it to work with the water pump 16 to control the drop height between the outlet and the water surface in the receiving tray 1, achieving a gentle spring flow and reducing water impact noise. The filter tray 3 has an integrated Roman column-shaped guide component inside, which connects to the water inlet of the receiving tray 1 and the pipe at the bottom of the filter tray 3. The water dispenser uses a simulated natural spring-like water flow at the outlet. By controlling the pump 16's head and the drop height of the outlet onto the water surface, the noise generated by the water flow impact from the outlet to the drinking tray is suppressed.

[0014] A control box 12 is installed on the side of the water tank 5. Inside the control box 12 are a PCB main board 9 and a battery 11. The PCB main board 9 is electrically connected to the water pump 16 and the infrared sensor board 10, receiving signals from the infrared sensor board 10 to control the start, stop, and speed of the water pump 16. This achieves automated control, starting the pump when the pet approaches and stopping it when the pet leaves, reducing the ineffective running time of the water pump 16, precisely controlling its speed, avoiding fluctuations in head that cause inconsistent water flow, ensuring a stable fountain effect, and making noise controllable. The infrared sensor board 10 inside the control box 12 senses the pet's approach and transmits the signal to the PCB main board 9. An indicator light panel 14 is installed on the side of the control box 12, corresponding to the position of the infrared sensor board 10. The indicator light panel 14 displays the device's operating status, providing intuitive feedback and allowing users to promptly detect abnormalities. The indicator light panel 14 is equipped with… The infrared sensor cover 15 and the water tank 5 are provided with a water level window 6 on the side. The water level window 6 is used to observe the remaining water in the water tank 5. The control box 12 is equipped with a coil 13 on the side. The coil 13 allows the power line or signal line connected to the internal components to pass through and the wire passage is sealed. The control box 12 is snapped with a control box back cover 7. The control box back cover 7 is provided with a charging port dust plug 8. The charging port dust plug 8 blocks the charging interface of the battery 11 on the control box back cover 7. The battery 11 provides independent power to the PCB motherboard 9, water pump 16 and infrared sensor board 10. By analyzing the three factors of water flow drop, impact height and water flow impact angle, the width of the return port and the guide angle of the drain are precisely designed at the water flow return port of the filter plate 3. This allows the return water to be accurately guided to the outer wall of the water pipe and back to the water tank 5 along the outer wall of the water pipe. This effectively controls the impact noise generated by the water flow directly injected into the water surface from a high place.

[0015] When a pet approaches the device, the infrared sensor 10 inside the control box 12 detects the pet's infrared signal and transmits it to the PCB mainboard 9. Upon receiving the signal, the PCB mainboard 9 immediately sends a start command to the water pump 16. The water pump 16 then starts operating, pumping water from the water tank 5 through the silicone hose 4 to the top inlet. Because the water pump 16 has a low-lift design, and the drop height between the outlet of the silicone hose 4 and the water surface in the water tray 1 is only 1-3cm, the water flows slowly and gently into the water tray 1 in a gentle, spring-like motion. There is no high-pressure jet or high-drop impact, and it does not produce the water flow impact noise of traditional water dispensers. The water circulation system allows pets to drink directly from the water tray 1 with a gentle flow of water. The grooved structure of the water tray 1 stabilizes the water flow range and prevents splashing. Excess water that is not consumed will flow naturally into the filter cotton 2 below through the gap between the water tray 1 and the filter disc 3. After being filtered by the filter cotton 2, the water flows to the Roman column-shaped guide inside the filter disc 3. Guided by the guide, the water flows precisely into the wall-mounted return port of the filter disc 3. The water will slowly fall along the outer wall of the silicone hose 4 and finally flow smoothly back into the water tank 5, completely avoiding the noise of water falling directly into the water tank from a height, achieving a silent circulation throughout the water channel. After the pet finishes drinking and leaves the device, the infrared sensor 10 no longer detects a signal. The PCB motherboard 9 will send a stop command to the water pump 16 after a delay of 5-10 seconds. The water pump 16 will then stop running, and the water circulation will cease.
