DETAILED DESCRIPTION

[0041] In order to better understand the purpose, structure and function of the present invention, the following Figure 1-13 , understanding of the present invention.

[0042] like Figure 1 A two-way inlet and outlet liquid container is designed, comprising a liquid container and a thermostat 1 connected to the bottom of the liquid container. The liquid container of this embodiment takes a kettle body 3 as an example. Figure 2 As shown, the thermostat 1 is provided with a water discharge check valve and a water inlet check valve; the water discharge check valve is connected to the inner cavity of the liquid container from the bottom of the liquid container; the water inlet check valve is connected to the inner cavity of the liquid container through an external water inlet conduit 31; the water inlet conduit 31 belongs to the outside of the inner cavity of the liquid container. The thermostat 1 can be detachably mounted on the bottom of the liquid container, and the thermostat 1 is embedded in the bottom of the liquid container. A bottom cover 5 with screws is provided below the thermostat 1. After the bottom cover 5 is buckled with the thermostat 1, it is screwed on the bottom of the liquid container by screws.

[0043] The innovation of the present invention lies in that a double-way inlet and outlet structure is provided on the liquid container, which can realize the inlet and outlet functions of the liquid container through an inlet pump and an outlet pump, so that the water in the liquid container can be drained and filled without manual operation, which greatly saves user time.

[0044] The drain check valve and the water inlet check valve are arranged vertically, and the drain check valve and the main water inlet and outlet channel are located on the same vertical center line. The drain check valve and the main water inlet and outlet channel form a vertical liquid channel, and the water inlet check valve forms a horizontal liquid channel. Figure 2 As shown, the combined structure of the vertical liquid channel and the horizontal liquid channel adds an internal structure inside the three-way valve of the prior art, so that the vertical liquid channel can control drainage, while the horizontal liquid channel can allow water to flow in, achieving different technical effects of switching between drainage and water flow.

[0045] The drainage check valve includes a total water inlet and outlet channel 112, a valve core sealing block 107 with a hollow structure inserted in the total water inlet and outlet channel 112, a first elastic component with a gap connected to the upper end of the valve core sealing block 107, a first movable blocking member connected to the upper end of the first elastic component with a gap, and a first movable blocking member that can movably resist a drainage sealing pad 101 with a hollow structure. The first elastic component with a gap and the first elastic component with a gap have gaps so that the components themselves will not block the water channel. At the same time, they are elastic, which can realize elastic control of the movement of the two respective blocking members, thereby blocking the liquid channel. Among them, the first elastic component with a gap is a drainage spring 103 or a spring with a gap, and the first movable blocking member is a steel ball 102. The drainage sealing pad 101 is fixed on the side wall of the inner cavity of the drainage check valve, and the first movable blocking member slides away from or close to the drainage sealing pad 101 to realize the opening or closing of the liquid channel inside the drainage check valve.

[0046] The water inlet check valve includes a limiting protrusion in the inner wall of the transverse liquid channel, one end of a second elastic component with a gap connected to the limiting protrusion, a second movable blocking member connected to the other end of the second elastic component with a gap, and a second movable blocking member that can movably resist a water inlet sealing gasket 108 with a hollow structure, wherein the second component with a gap is a water inlet spring 106 or a spring clip with a gap; the second movable blocking member is a water inlet block 105.

[0047] The water inlet sealing gasket 108 is fixed on the inner cavity side wall of the water inlet check valve close to the first elastic component with a gap, and the second movable blocking member slides away from or close to the water inlet sealing gasket 108, thereby opening or closing the internal liquid channel of the water inlet check valve.

[0048] like Figure 2 and 7 As shown, the thermostat 1 includes a temperature control support 110, in which a three-way valve core 109 is installed. The three-way valve core 109 has the same channel as the three-way valve. The upper mouth of the three-way valve core 109 is also sleeved with a sealing ring 111. The upper mouth of the three-way valve core 109 is inserted into the bottom of the liquid container and extends into the inner cavity of the liquid container. One end of the lower part of the three-way valve core 109 is the main inlet and outlet water channel, and the other two ends of the upper part are respectively connected to the drainage check valve and the water inlet check valve; when draining water, the water flows through the inner cavity of the liquid container, the drainage check valve, and the total inlet and outlet water channel in sequence; when inlet water, the water flows through the total inlet and outlet water channel, the water inlet check valve, the water inlet conduit 31, and the inner cavity of the liquid container in sequence.

[0049] When draining, the water inlet check valve is self-locking and closed, and the water in the liquid container is discharged only from the opened drain check valve; wherein, the drain check valve includes a drainage sealing gasket 101, a steel ball 102, a drainage spring 103, and a spring bracket 104. Since the drainage sealing gasket 101, the steel ball 102, the drainage spring 103 and the spring bracket 104 form a sealing structure, under normal conditions, the steel ball 102 will form a sealing state with the drainage sealing gasket 101 due to the elastic force of the drainage spring 103, and water can only enter the conduit 6 from the kettle body 3, which has a check function.

[0050] When water is entering, the water discharge check valve is closed by self-locking, and water is only input into the liquid container from the opened water inlet check valve. The water inlet valve port 4 is composed of a water inlet stopper 105, a water inlet spring 106, and a water inlet sealing gasket 108. Since the water inlet stopper 105, the water inlet spring 106 and the water inlet sealing gasket 108 form a sealing structure, under normal conditions, the water inlet stopper 105 forms a sealing state with the water inlet sealing gasket 108 due to the elastic force of the water inlet spring 106, and water can only enter the water inlet conduit 5 from the conduit 6, which also has a check function.

[0051] like Figure 8 The electric kettle comprises a kettle body 3 and a base 4 supporting the kettle body 3. A drainage pump and a water inlet pump are installed on the base 4. The drainage pump is connected to the middle pipe 202 through a drainage pipe, and the water inlet pump is connected to the middle pipe 202 through an inlet pipe. The base 4 is used to control the heating of the kettle body 3, and a controller for controlling the water inlet and water discharge of the thermostat 1 is installed in the base 4. The kettle body 3 is the above-mentioned two-way liquid container for water inlet and water discharge, and the water inlet conduit 31 is set in the handle of the side wall of the kettle body 3.

[0052] like Figure 3 As shown, the upper end surface of the base 4 is provided with a coupler 2, and a middle pipe 202 is movably inserted in the coupler 2, and the middle pipe 202 is detachably connected to the main water inlet and outlet channel 112.

[0053] like Figure 4 and 7 As shown, a large spring 203 is sleeved on the middle tube 202 , and the large spring 203 is installed in the inner cavity of the coupler 2 . When the thermostat 1 at the bottom of the kettle body 3 is seated on the coupler 2 , the water path in the thermostat 1 is connected to the middle tube 202 .

[0054] Working principle: 1. The specific movement process of the automatic water inlet of the product is as follows: when the kettle body 3 is placed on the base 4, click the intelligent water boiling mode, the controller sends a control signal to control the water inlet pump set on the base 4 to work, the water inlet pump pumps water in the forward direction, and the water in the water tank or bucket enters through the conduit 6 connected to the coupler 2 due to the pressure difference generated by the water pump. The water enters the conduit 6 connected to the coupler 2 through the water inlet pump and the water inlet valve port 4 set on the base 4, and then enters the water valve set on the thermostat 1. Since the internal structure of the drainage check valve in the water valve has a check function, water can only enter the water inlet conduit 31 set on the handle through the water inlet check valve, and then enter the kettle body 3. When the water inlet pump stops working, the water inlet stopper 105 in the water inlet check valve will be reset due to the elastic force of the water inlet spring 106, and form a seal with the water inlet sealing gasket 108, and the kettle body 3 will then start heating to complete the water boiling.

[0055] 2. The specific movement process of the automatic drainage of the product is as follows: when the kettle body 3 is placed on the base 4, if there is residual water in the kettle, the user can click the drainage function, the intelligent mode, the controller sends a control signal to control the drainage pump set on the base 4 to work, and the water in the kettle body 3 pushes the steel ball 102 through the drainage check valve and enters the water core. Since the structure in the water inlet check valve also has a check function, water can only enter the base 4 through the conduit 6. A three-way valve is also set in the base 4, and the water is discharged through the three-way valve in the base 4 and the drainage pump.
