Description

Technical Field

[0001] This utility model relates to the technical field of formula milk maker equipment, specifically to a formula milk maker that is pump-free and leaves no residual water. Background Technology

[0002] Most formula makers on the market currently use a design with a detachable rear water tank and a front spout. Since the spout is usually positioned higher than the bottom of the water tank, a silicone hose connects the tank and spout, relying on a water pump for power. While this design achieves the desired water delivery, it has significant drawbacks in practical use: the pump generates mechanical vibration and noise, affecting the infant's rest environment; furthermore, some water remains on the silicone hose after dispensing, which can accumulate over time, fostering bacterial growth and limescale formation, posing a hygiene and safety hazard.

[0003] The main problems with existing technologies lie in the design of the water delivery system. As the core power component, the water pump's operating noise is difficult to completely eliminate; while the silicone hose, as the water delivery channel, not only poses hygiene risks but also suffers from aging and deformation due to long-term use, as well as the accumulation of scale and other impurities, requiring frequent replacement and maintenance. Customers generally lack the means to replace these hoses, resulting in high after-sales maintenance costs. These problems are particularly prominent in the infant and toddler product sector, as these products have extremely high requirements for noise control and water quality hygiene.

[0004] To address the aforementioned issues, there is an urgent need for a formula maker that eliminates the need for a pump and leaves no residual water, thus resolving these technical problems. Summary of the Invention

[0005] In response to the problems in related technologies, this utility model proposes a pump-free and water-residual formula maker, which features quiet operation, no residual water, and simple structure, while maintaining stable water delivery performance.

[0006] This utility model is implemented as follows:

[0007] A pump-free and water-residual formula maker includes a kettle and a water outlet base; the kettle is mounted on the upper side of the water outlet base; a heating module is provided at the bottom of the kettle;

[0008] The front of the water outlet base is recessed towards the back to form a receiving cavity, making the side view of the water outlet base appear as a C-shaped opening; the upper and lower sides of the receiving cavity of the water outlet base are respectively an upper convex part and a lower convex part; the lower surface of the upper convex part has a partially exposed water outlet nozzle, and the water outlet nozzle extends upward into the inner cavity of the upper convex part.

[0009] The inner cavity of the upper protrusion is also equipped with a solenoid valve; the solenoid valve has a water passage installed vertically, with its upper end connected to the kettle and its lower end connected to the water outlet; the water outlet base is equipped with at least two switches, which are electrically connected to the solenoid valve and the heating module respectively.

[0010] The lower protrusion and receiving cavity serve as a placement area for the water container, allowing it to be placed directly below the spout. The kettle is positioned directly above the spout base, utilizing gravity as the power source for water dispensing, eliminating the need for a water pump. Solenoid valves are directly connected to both the spout and the kettle, eliminating the need for water pipes and preventing residual water.

[0020] The valve body includes a connecting part that connects to a pipe or pipe opening, and a communicating chamber that communicates with the connecting part, with two valve bodies fixedly connected at the communicating chamber;

[0021] The electromagnetic coil assembly includes an axially movable moving core, the end of which is fixedly connected to a piston; the piston is placed in one of the communicating chambers.

[0022] When the electromagnetic coil assembly is energized or de-energized, the moving core drives the piston to connect or isolate the two connecting chambers.

[0023] Specifically, when the electromagnetic coil is de-energized, the moving core is reset by a built-in spring.

In this embodiment, the kettle 1 includes a built-in cup body 11, with openings at both the upper and lower ends, and a heat-conducting plate 13 is provided at the lower opening for a sealed connection. A heating coil 12 is fixed to the lower side of the heat-conducting plate 13; the heat-conducting plate 13 and the heating coil 12 form a heating module. A temperature sensor 14 is also sealed and connected to the upper surface of the heat-conducting plate 13. Specifically, the temperature sensor 14 is an NTC thermistor.

[0051] The front of the water outlet base 2 is recessed to the back, forming a receiving cavity 21, so that the side view of the water outlet base 2 is C-shaped opening; the upper and lower sides of the receiving cavity 21 of the water outlet base 2 are respectively the upper convex part 22 and the lower convex part 23.

[0052] In this embodiment, a water receiving tray 3 is fixed to the upper surface of the lower protrusion 23. The lower protrusion 23 and the receiving cavity 21 serve as the placement area for the water receiving container, allowing the water receiving container to be placed directly below the water outlet 4 and directly above the water receiving tray 3.

[0053] The lower surface of the upper protrusion 22 has a partially exposed water outlet 4, which extends upward into the inner cavity of the upper protrusion 22.

The upper surface of the water outlet base 2 is provided with a recessed fixing groove 24; the bottom of the kettle 1 is adapted to the fixing groove 24. The kettle 1 and the water outlet base 2 are connected by a coupler.

[0055] In this embodiment, the coupler is a water-electric coupler 5; the coupler includes an upper coupling component 51 disposed at the bottom of the kettle 1, and a lower coupling component 52 fixedly disposed in the center of the fixing groove 24.

[0056] The upper coupling assembly 51 includes a vertical fluid channel 53, within which an axially movable sealing ball 54 and a return spring 55 abutting against the ball are installed. The fluid channel 53 extends upward to communicate with the inner cavity of the cup body 11.
