Abstract

This utility model relates to the field of water purifier technology and discloses a fully automatic smart kettle, including a water inlet and a water outlet. A magnetic control valve containing a moving iron core is installed inside the water inlet, close to the outer shell of the water outlet. A buoyancy component containing a first magnet is installed inside the lid of the water outlet, close to the side of the water inlet. When the water outlet is empty, the first magnet and the moving iron core are axially aligned and attracted to each other by magnetic force. The fully automatic smart kettle controls the opening and closing of the magnetic control valve through the magnetic force of the first magnet and the moving iron core, realizing water inlet and water stop. When the water outlet is empty, the moving iron core in the magnetic control valve is attracted to the first magnet in the buoyancy component and moves to the right, aligning closely with the first magnet, allowing water to enter the water outlet. When the water level rises to the rated position, the float in the buoyancy component moves the first magnet away from its aligned position with the moving iron core, stopping water inlet. The entire process of water inlet and water stop in the smart kettle requires no electricity or manual operation, making it convenient and quick.

Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, specifically to a fully automatic smart kettle. Background Technology

[0002] Currently, smart kettles on the market suffer from several drawbacks, including the need for a power source, limited applicability, high maintenance costs, and cumbersome operation. For example, there are two main types of smart kettles: one uses electricity, which senses water level changes through electrical components and controls the water flow via an electronic valve, increasing usability limitations and maintenance costs; the other, without electricity, requires manual operation to open the water inlet, which is also cumbersome. For instance, Chinese invention patent CN112842082A discloses a "smart kettle for water purifiers," which requires manually pushing a "pushing device" to open the water inlet, a cumbersome process. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To address the problems of existing smart kettles requiring power supply, limited applicability, high maintenance costs, and cumbersome operation, this invention provides a fully automatic smart kettle that controls the opening and closing of the water circuit by changing the position of a first magnet due to changes in the water level inside the kettle, thereby achieving fully automatic water intake and shut-off.

[0005] (II) Technical Solution:

[0006] The fully automatic smart kettle includes a water inlet and a matching water outlet. A magnetic control valve is installed inside the water inlet, close to the outer shell of the water outlet. A buoyancy component is installed inside the lid of the water outlet, near the water inlet. The magnetic control valve contains a moving iron core, and the buoyancy component contains a first magnet. When the water outlet is empty, the first magnet and the moving iron core are axially aligned and attracted to each other by magnetic force.

[0007] Preferably, the magnetic control valve consists of a valve core and a valve body. The valve core consists of a return spring, a moving iron core, and a plug. The moving iron core is nested inside the return spring. The left side of the return spring is connected to the protrusion on the left side of the moving iron core. A plug is fixed to the top left side of the moving iron core.

[0008] Preferably, the valve body has a sleeve containing a return spring and a moving iron core. A plug on the moving iron core has a central hole on its left side, which connects to the central water groove on its left side and the cavity on its right side. The valve body contains a circular diaphragm with a central hole and an eccentric hole. The left side of the circular diaphragm has a central water groove and an outer ring water groove, while the right side has a cavity. The circular diaphragm separates the central water groove, the outer ring water groove, and the cavity. The eccentric hole connects the left outer ring water groove and the right cavity. The outer ring water groove is connected to the inlet of the upper kettle via a water pipe, and the central water groove is connected to the outlet of the upper kettle via a water pipe.

[0009] Preferably, the buoyancy assembly consists of a float, a first magnet, a rotating shaft, and a limiting protrusion. The first magnet is fixed to the float near the upper end of the kettle. The float is connected to the kettle lid via the rotating shaft. The kettle lid has a limiting protrusion that supports the float.

[0010] Preferably, when the water container is placed in the fixed water-receiving position to the right of the upper water container, a third magnet and a second magnet that attract each other for positioning are installed on the outer shells of the water container and the upper water container at their respective aligned positions.

[0011] Preferably, the circular tympanic membrane is composed of a soft rubber pad and a plastic pad nested on the soft rubber pad.

[0012] Preferably, the upper water bottle base has a slide rail to guide the water bottle into the fixed water-filling position.

[0013] When a water jug ​​empty or with a water level below the rated position is placed in the fixed water-filling position on the right side of the upper water jug, the moving iron core in the magnetic control valve is attracted by the first magnet in the buoyancy assembly. The moving iron core, along with the stopper, moves to the right, opening the central hole. When the inlet water pressure and flow rate are low, water in the outer ring water tank flows into the central water tank through the eccentric hole, the cavity, and the central hole. When the inlet water pressure and flow rate are high, the water pressure in the cavity drops as water flows into the central water tank through the central hole, falling below the water pressure in the outer ring water tank on the left side of the circular diaphragm. The water in the outer ring water tank pushes the circular diaphragm to deform to the right, and most of the water in the outer ring water tank flows directly into the central water tank from the left side of the circular diaphragm. A small portion of the water flows into the central water tank through the eccentric hole, the cavity, and the central hole, opening the magnetic control valve and allowing water to enter the water jug.

[0014] When the water level in the kettle rises to the rated position, the float on the buoyancy assembly is driven by buoyancy to move the first magnet away from the moving iron core in the magnetic control valve and close to the alignment position. The attraction of the moving iron core to the first magnet is weaker than the force of the return spring on the moving iron core. Under the action of the return spring, the moving iron core and the plug move to the left together. The plug blocks the central hole, and the water in the outer water tank flows into the cavity through the eccentric hole. The water pressure in the cavity increases, and the water in the cavity and the return spring push the circular diaphragm to deform to the left. The circular diaphragm and the plug together cover the central water tank, the magnetic control valve closes, and the kettle stops filling with water.

[0015] When the water jug ​​is removed from its fixed water-filling position next to the upper water jug, the moving iron core, under the action of the return spring, moves to the left along with the stopper. The stopper blocks the central hole, and the water in the outer ring water tank flows into the cavity through the eccentric hole. The water pressure in the cavity increases, and the water in the cavity and the return spring push the circular diaphragm to deform to the left. The circular diaphragm, together with the stopper, tightly covers the central water tank, the magnetic control valve closes, and the water jug ​​stops filling with water.

[0016] (III) Beneficial Effects:

[0017] The fully automatic smart kettle consists of a filling kettle and a filling kettle. A magnetic control valve containing a moving iron core is installed inside the filling kettle, close to the outer shell of the filling kettle. A buoyancy component containing a first magnet is installed inside the filling kettle lid, close to the filling kettle. The fully automatic smart kettle uses the magnetic force between the first magnet and the moving iron core to control the opening and closing of the magnetic control valve, thus controlling water intake and shut-off. The entire process of filling and shutting off water in the filling kettle requires no electricity and no manual operation, making it convenient and quick. Attached Figure Description

The following description presents a preferred embodiment of several possible embodiments of this utility model, intended to provide a basic understanding of the utility model, but not intended to identify the key or decisive elements of the utility model or to limit the scope of protection sought.

[0024] The fully automatic smart kettle includes a water inlet (1) and a matching water container (2). A magnetic control valve (4) is installed inside the water inlet (1) on the outer shell of the water container (2) on one side. A buoyancy component (3) is installed inside the lid of the water container (2) on the side near the water inlet (1). The magnetic control valve (4) contains a moving iron core (5). The buoyancy component (3) contains a first magnet (9). When the water container (2) is empty, the first magnet (9) and the moving iron core (5) are axially aligned and attracted to each other by magnetic force.

[0025] The magnetic control valve (4) consists of a valve core and a valve body. The valve core consists of a return spring (13), a moving iron core (5), and a plug (8). The return spring (13) has a moving iron core (5) nested inside it. The left side of the return spring (13) is connected to the protrusion on the left side of the moving iron core (5). The plug (8) is fixed at the top left side of the moving iron core (5).

[0026] The valve body has a sleeve (15), inside which there is a return spring (13) and a moving iron core (5). The plug (8) on the moving iron core (5) has a central hole (6) on its left side, which connects the central water tank (17) on its left side and the cavity (21) on its right side. The valve body has a circular diaphragm (16), which has a central hole (6) and an eccentric hole (7). The left side of the circular diaphragm (16) has a central water trough (17) and an outer ring water trough (18), and the right side of the circular diaphragm (16) has a cavity (21). The circular diaphragm (16) separates the central water trough (17), the outer ring water trough (18), and the cavity (21). The eccentric hole (7) connects the left outer ring water trough (18) and the right cavity (21). The outer ring water trough (18) is connected to the inlet (20) of the upper water jug ​​(1) through a water pipe, and the central water trough (17) is connected to the outlet (19) of the upper water jug ​​(1) through a water pipe.

[0027] The buoyancy component (3) consists of a float (10), a first magnet (9), a rotating shaft (11), and a limiting protrusion (12). The first magnet (9) is fixed on the float (10) near the end of the upper kettle (1). The float (10) is connected to the kettle lid through the rotating shaft (11). The kettle lid has a limiting protrusion (12) that holds the float (10).

[0028] When the water container (2) is placed in the fixed water receiving position on the right side of the upper water container (1), the water container (2) and the upper water container (1) are respectively equipped with a third magnet (23) and a second magnet (22) that attract each other for positioning on their respective outer shells close to each other.

[0029] The circular tympanic membrane (16) consists of a soft rubber pad and a plastic pad nested on the soft rubber pad.

[0030] The base of the upper kettle (1) has a slide rail (24) that guides the water-filled kettle (2) to slide into the fixed water-filling position.

[0031] When a water jug ​​(2) with no water or water level below the rated position is placed in the fixed water receiving position on the right side of the upper water jug ​​(1), the moving iron core (5) in the magnetic control valve (4) is attracted by the first magnet (9) in the buoyancy assembly (3), and the moving iron core (5) moves to the right together with the plug (8), and the central hole (6) opens. When the inlet pressure and flow rate are low, the water in the outer ring water tank (18) flows into the central water tank (17) through the eccentric hole (7), the cavity (21), and the central hole (6). When the inlet pressure and flow rate are high, the water in the cavity (21) flows into the central water tank (17) through the central hole (6), causing the water pressure in the cavity (21) to drop and become lower than the water pressure in the outer ring water tank (18) on the left side of the circular diaphragm (16). The water in the outer ring water tank (18) pushes the circular diaphragm (16) to deform to the right. Most of the water in the outer ring water tank (18) flows directly into the central water tank (17) from the left side of the circular diaphragm (16), and a small portion of the water flows into the central water tank (17) through the eccentric hole (7), the cavity (21), and the central hole (6). The magnetic control valve (4) is opened, and the water jug ​​(2) is filled with water.

[0032] When the water level in the kettle (2) rises to the rated position, the float (10) on the buoyancy assembly (3) is driven by the buoyancy to move the first magnet (9) away from the moving iron core (5) in the magnetic control valve (4) and close to the alignment position. The attraction of the moving iron core (5) by the first magnet (9) is weaker than the force of the return spring (13) on the moving iron core (5). Under the action of the return spring (13), the moving iron core (5) moves to the left together with the plug (8). The plug (8) blocks the central hole (6). The water in the outer ring water tank (18) flows to the cavity (21) through the eccentric hole (7). The water pressure in the cavity (21) increases. The water in the cavity (21) along with the return spring (13) pushes the circular diaphragm (16) to deform to the left. The circular diaphragm (16) along with the plug (8) covers the central water tank (17). The magnetic control valve (4) closes and the kettle (2) stops water intake.

[0033] When the water jug ​​(2) is removed from the fixed water-filling position next to the upper water jug ​​(1), the moving iron core (5) moves to the left together with the plug (8) under the elastic force of the return spring (13). The plug (8) blocks the central hole (6), and the water in the outer ring water tank (18) flows to the cavity (21) through the eccentric hole (7). The water pressure in the cavity (21) increases, and the water in the cavity (21) along with the return spring (13) pushes the circular diaphragm (16) to deform to the left. The circular diaphragm (16) along with the plug (8) covers the central water tank (17), the magnetic control valve (4) closes, and the water jug ​​(2) stops filling with water.

[0034] The fully automatic smart kettle includes a water inlet (1) and a water outlet (2). A magnetic control valve (4) containing a moving iron core (5) is installed inside the water inlet (1) and close to the outer shell of the water outlet (2). A buoyancy component (3) containing a first magnet (9) is installed inside the lid of the water outlet (2) and close to the side of the water inlet (1). The fully automatic smart kettle controls the opening and closing of the magnetic control valve (4) through the magnetic force of the first magnet (9) and the moving iron core (5), thus achieving water inlet and water outage. The entire process of water inlet and water outage in the fully automatic smart kettle's water outlet (2) requires no electricity and no manual operation, making it convenient and quick.
