[0022] Compared with the traditional structure, this water core has a sealing component fixedly connected to the elastic leak-proof cap 3 through the connecting rod 2, so that the sealing component and the elastic leak-proof cap 3 can move synchronously through the connecting rod 2. When the sealing component seals or opens the lower water inlet and outlet 102, the elastic leak-proof cap 3 seals or opens the upper water inlet and outlet 101 at the same time, so that the water core has a double sealing effect in both directions, thereby improving the sealing performance of the water core, and the water core has both water supply and water discharge functions.

[0023] A mounting bracket 11 is provided at the top of the water inlet sleeve 1, and a center hole 104 is opened on the mounting bracket 11. The connecting rod 2 is slidably connected in the center hole 104. Several upper water inlets and outlets 101 surrounding the center hole 104 are formed between the mounting bracket 11 and the water inlet sleeve 1, and the elastic leak-proof cap 3 is placed above the several upper water inlets and outlets 101; the diameter of the center hole 104 just matches the diameter of the connecting rod 2, so that the center hole 104 has a guiding function, and the arrangement of several upper water inlets and outlets 101 can make the water spray out evenly.

[0024] The sealing assembly includes a sealing steel ball 4 and a steel ball seat 5. The sealing steel ball 4 is sealed against the lower water inlet and outlet 102. The steel ball seat 5 is placed above the sealing steel ball 4 and is integrally fixedly connected to the lower end of the connecting rod 2. A positioning groove 401 matching the shape of the upper half of the sealing steel ball 4 is provided on the steel ball seat 5. The steel ball seat 5 uses the positioning groove 401 to center the sealing steel ball 4 in the water inlet and outlet channel 103.

[0025] The sealing assembly also includes a water inlet sealing sleeve 6 made of elastic material, which is interference fit into the bottom of the water inlet sleeve 1, and a lower water inlet and outlet 102 is provided in the water inlet sealing sleeve 6; a sealing arc surface 601 is provided on the upper part of the lower water inlet and outlet 102, and the lower half of the sealing steel ball 4 is sealed against the sealing arc surface 601; when the sealing steel ball 4 is reset, the sealing arc surface 601 is attached to the outer wall surface of the sealing steel ball 4, so that the lower water inlet and outlet 102 can be closed.

[0026] The elastic reset member includes a reset spring 7, which is sleeved on the outside of the connecting rod 2, and the two ends of the reset spring 7 are against each other between the mounting bracket 11 and the steel ball seat 5; the reset spring 7 is sleeved on the connecting rod 2 so that the connecting rod 2 plays a guiding role, and the elastic potential energy of the reset spring 7 is in the center position, so that the steel ball seat 5 is subjected to more uniform force.

[0027] Combined with the above structure, when the water supply function is realized:

[0028] The sealing steel ball 4 is lifted up by the lifting structure, and the sealing steel ball 4 is separated from the sealing arc surface 601. At the same time, the connecting rod 2 slides upward and lifts the elastic leak-proof cap 3 synchronously, and the elastic leak-proof cap 3 leaves the top of the water inlet sleeve 1. At this time, the lower water inlet and outlet 102 and the upper water inlet and outlet 101 are opened at the same time, and the water supplied by the water pump enters the water inlet and outlet channel 103 from the lower water inlet and outlet 102, and then enters the inner cavity of the kettle through the upper water inlet and outlet 101 to realize water supply;

[0029] During the use of the kettle, the sealing steel ball 4 and the elastic leak-proof cap 3 remain in the jacked-up state, so that the upper water inlet and outlet 101 and the lower water inlet and outlet 102 are always open; or when the jacking structure can realize automatic lifting in the thermostat coupling state, the jacking structure can be lowered after the water is filled, so that the sealing steel ball 4 and the elastic leak-proof cap 3 are reset, so that the lower water inlet and outlet 102 and the upper water inlet and outlet 101 are closed in the heating state;

[0030] When the water outlet function is realized: since the lower water inlet and outlet 102, the upper water inlet and outlet 101 and the water inlet and outlet channel 103 remain connected, or the lifting structure lifts up the sealing steel ball 4 and the elastic leak-proof cap 3 again, it is only necessary to pump water in the reverse direction by the water pump, that is, the water in the inner cavity of the kettle can be pumped out to realize the bottom water outlet;

[0031] When the kettle is lifted, the force of the lifting structure under the sealing steel ball 4 disappears, so under the elastic potential energy of the reset spring 7, the steel ball seat 5 and the elastic leak-proof cap 3 are reset, and under the continuous elastic potential energy, the steel ball seat 5 is pressed against the sealing arc surface 601, and the elastic leak-proof cap 3 is pressed against the top surface of the water inlet sleeve 1 to cover all the upper water inlets and outlets 101.

[0032] The elastic leak-proof cap 3 is an umbrella-shaped structure that is high in the middle and low around. The elastic leak-proof cap 3 is detachably connected to the upper end of the connecting rod 2. The elastic leak-proof cap 3 is made of silicone material or rubber material. The elastic leak-proof cap 3 with this structure can improve the sealing effect.

[0033] The bottom of the water inlet sealing sleeve 6 extends outward to form a limit flange 602, and the limit flange 602 is limitedly held against the bottom edge of the water inlet sleeve 1; the limit flange 602 cooperates with the bottom edge of the water inlet sleeve 1 to stop the installation of the water inlet sealing sleeve 6 and control the installation depth of the water inlet sealing sleeve 6;

[0034] The lower part of the lower water inlet and outlet 102 is a plug-in interface 603, and the water inlet sealing sleeve 6 extends to the plug-in interface 603 with a plurality of circles of sealing ribs 604 arranged at intervals from top to bottom; in the thermostat coupler, the jack is inserted into the plug-in interface 603 to achieve the connection between the upper and lower water inlet channels, and the sealing ribs 604 can improve the sealing effect between the two.

[0035] The outer wall of the water inlet sleeve 1 is circumferentially extended with a supporting ring 12 close to the upward water inlet and outlet 101, and the top cover of the water inlet sleeve 1 is provided with a top cover 8, which is supported on the supporting ring 12; the upper part of the top cover 8 is truncated cone-shaped, and a plurality of evenly distributed water inlet and outlet holes 801 are opened on its circumferential wall; the top cover 8 can block the axially sprayed water column, and can prevent the water column from spraying out of the kettle even if the kettle cover is not in place.

[0036] The supporting ring 12 is supported by a silicone sealing ring 9, which is sleeved on the outer periphery of the top cover 8; the silicone sealing ring 9 mainly seals the gap between the water core and the water core installation hole to achieve a sealing effect.

[0037] A temperature controller comprises a connecting upper seat, on which the water core is installed.
