Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and particularly relates to an upper water intake type drinking fountain with a mechanical anti-drip function. Background Art

[0002] Most of the existing tabletop water purifiers adopt the way of water inlet from the lower part of the water tank / kettle, and such a way has great disadvantages (① it is impossible to achieve true separation of water and electricity; ② if there is a water leakage situation, since water is a conductor of electricity, it is easy to cause a short circuit and explosion of the machine). To solve this problem, the prior art has improved the water intake method of the drinking fountain and designed an upper water intake type drinking fountain. The currently popular upper water intake type drinking fountain mainly consists of three major parts: a main unit, a boiling kettle, and a water intake cover. The main unit is designed with a water outlet nozzle and a water pump, and the boiling kettle is provided with a water storage cavity with an opening at the top. During daily use, the user needs to inject clean water into the water storage cavity from the upper end of the boiling kettle and tightly seal it with the water intake cover to ensure the tightness of the system. The water intake cover is internally configured with a water delivery pipeline communicating with the water outlet nozzle and the water storage cavity. When the user needs hot water, just start the water pump, and the water that has been heated to boiling will flow smoothly from the water storage cavity to the water outlet nozzle along the waterway system in the water intake cover for the user to use.

[0003] However, there is a problem with the current upper water intake type drinking fountain: after each water intake, there is always some water remaining in the water delivery pipeline, making it easy for the user to be scalded by the dripping hot water when removing the water intake cover. Summary of the Invention

[0004] The invention object of the utility model is to solve the problem of residual water in the pipeline of the existing upper water intake type drinking fountain, and provide an upper water intake type drinking fountain with a mechanical anti-drip function.

[0005] To achieve the above invention object, the utility model adopts the following technical solutions:

[0006] An upper water intake type drinking fountain with a mechanical anti-drip function, comprising a main unit, a water intake cover, a water boiling device, and a waterway system. The water boiling device is assembled on the side of the main unit, and the upper side of its water cavity is open. The water intake cover is detachably assembled on the upper end of the main unit and closes the water cavity. The waterway system includes a water inlet system arranged on the water intake cover and a water outlet system arranged on the main unit. The input end of the water inlet system corresponds to the water cavity and extends into the water cavity. The output end of the water inlet system is detachably communicated with the input end of the water outlet system. An internal sealing structure is arranged at the output end of the water inlet system, and a driving mechanism is arranged at the input end of the water outlet system. The internal sealing structure can be switched from a sealed state to an open state under the drive of the driving mechanism.

[0007] For the above-water intake type water dispenser of the present utility model, the output end of its water inlet system has an internal sealing structure. When the water intake cover is assembled in place, the driving mechanism drives the internal sealing structure into an open state, thereby connecting the water inlet system and the water outlet system. After the water intake cover is removed, the internal sealing structure automatically turns into a sealed state to prevent water from overflowing from the output end. At the same time, since the output end is closed, the water in the water inlet system is pressed inward under atmospheric pressure and will not overflow from the input end, thus realizing the anti-drip function. Compared with the prior art, the above-water intake type water dispenser of the present utility model adopts a mechanical anti-drip structure, which does not rely on software or circuit control, simplifies the design and improves the reliability. Moreover, when the water intake cover is removed, the internal sealing structure automatically turns into a sealed state, effectively preventing water from overflowing from the output end of the water inlet system and avoiding potential hygiene problems.

[0008] Furthermore, the output end of the water inlet system includes a second interface penetrating through the water intake cover, the internal sealing structure is arranged in the second interface, the input end of the water outlet system is provided with a third interface, the driving mechanism is arranged in the third interface, the second interface is detachably connected to the third interface, and an external sealing structure is arranged between the second interface and the third interface. In this solution, the external sealing structure is used to seal the gap between the second interface and the third interface, making their connection tight and preventing water from overflowing between the interfaces.

[0009] Further, the internal sealing structure includes an internal connection hole arranged in the second interface and an elastic pressing switch elastically pressed at the internal connection hole. The driving mechanism includes a thimble. When the second interface is connected to the third interface, the thimble pushes the elastic pressing switch upward to open the internal connection hole. When the second interface is separated from the third interface, the elastic pressing switch resets and closes the internal connection hole. In this solution, when the internal sealing structure is in a sealed state, the first pressing block presses on the internal connection hole to close the internal connection hole. When the second interface is connected to the third interface, the thimble pushes the second pressing block upward, so that the elastic pressing switch is displaced upward as a whole, and the first pressing block disengages from the internal connection hole, opening the internal connection hole. After the displacement is in place, the thimble presses on the second pressing block to keep the internal sealing structure in an open state. When the second interface is separated from the third interface, the elastic pressing switch resets under the elastic force of the elastic resetting member and closes the internal connection hole again.

[0010] Furthermore, the second interface and the third interface are connected by plugging and unplugging, and the external sealing structure is an elastic sealing ring. The structural design of this solution has a guiding effect on the assembly of the water intake cover and can improve the convenience of assembly.

[0011] Further, the second interface includes an annular first connection part, a second connection part, and a third connection part. The upper end of the first connection part is connected to the conveying pipeline of the water inlet system, and the lower end is connected to the upper end of the second connection part. The second connection part protrudes downward from the bottom of the water intake cover and is connected to the water outlet system. The third connection part is arranged at the connection of the first connection part and the second connection part and protrudes radially inward to form an inner connection hole.

A limiting groove is correspondingly arranged at the upper end of the main machine for the installation convex part, and the third interface is located at the limiting groove. The limiting groove and the installation convex part in this solution cooperate to play a role in positioning and guiding the assembly of the water intake cover.

[0014] Further, the input end of the water outlet system includes a connecting member. The connecting member is arranged inside the main machine. The third interface is arranged on the connecting member. The ejector pin is connected to the inner wall of the third interface through a connecting rib.
