Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps, and in particular relates to a water pump with a one-way anti-backflow structure for a double-furnace automatic water-filling tea tray. Background Art

[0002] In daily life, tea tray watering systems often require automatic watering to ensure timely and convenient tea supply. Traditional automatic watering systems typically use a water pump to supply water to the tea tray. However, these water pump systems present several technical challenges, including reverse water flow when two or more pumps share the same inlet and outlet pipes, making it impossible to achieve specific water supply methods for the tea tray, and damage to the pumps caused by backflow of high-temperature water or steam.

[0003] Specifically, when multiple water pumps share the same water inlet pipe, if one pump starts pumping, the other stationary pumps will be affected by the negative pressure effect within the system, causing unnecessary air or water discharge from the stationary pumps, affecting their normal operation and lifespan. Furthermore, in some applications requiring heating, the water pumps may be exposed to high-temperature water or steam. If this high-temperature water or steam flows back into the pump when it stops working, it will not only shorten the pump's service life, but also bring potential risk of equipment damage and increase repair and replacement costs.

[0004] In view of this, overcoming the defects of the above-mentioned prior art is an urgent problem to be solved in this technical field. Utility Model Content

DETAILED DESCRIPTION

[0016] like Figs. 1 to 3 As shown, a water pump with a one-way anti-backflow structure for a double-furnace automatic water-filling tea tray includes a water pump body 10, and a water pump cover 20 is installed on the upper part of the water pump body 10. The water pump cover 20 is fixed to the edge of the water pump body 10 by fasteners, and a water outlet 21 and a water inlet 22 are respectively provided on the surface of the water pump cover 20. A check valve core 30 is connected to the water outlet 21, and an anti-water outlet valve core 40 is connected to the water inlet 22. When in use, the water outlet 21 serves as the water outlet end of the water pump and is connected to an external water outlet hose for draining out the water flow inside the water pump. The check valve core 30 plays a role of one-way flow guidance. When the water pump pushes the water flow, water can flow out through the check valve core 30, and when the water pump stops or is subjected to external pressure, the check valve core 30 will automatically close to prevent external water or steam from flowing back into the water pump. The water inlet nozzle 22 serves as the water inlet end of the water pump and is connected to the water inlet hose to provide a continuous water source for the water pump. The function of the anti-outflow valve core 40 is to push the valve core open by the direction of the water pipe flow force to allow water to enter the water pump in one direction. When the water pump stops, the water valve core 40 will automatically close due to the reverse reflux force of the water pipe, preventing the water in the water pump from flowing out in the opposite direction through the water inlet nozzle. This design is particularly important when multiple pumps share a water inlet pipe to form a closed water circuit. When two or more water pumps share a water inlet pipe, when one water pump starts to pump water, the other water pumps may be affected by negative pressure when they stop, causing the stopped water pump to generate airflow to discharge. This discharged gas will be blocked by the anti-outflow valve core to ensure that only the started water pump can discharge water normally.
