[0027] See also Figures 1 to 4 The present invention provides an inner and outer layered filtering kettle, comprising: a kettle body 100; a container assembly 200, which is detachably mounted on the kettle body 100, the container assembly 200 comprising an outer shell 210 and an inner shell 220 disposed inside the outer shell 210 and spaced apart from the outer shell 210, the inner cavity of the inner shell 220 constituting a raw water cavity 221, and the area between the outer shell 210 and the inner shell 220 constituting a purified water cavity 211; a filter element assembly 300, which is disposed inside the kettle body 100; The input end of the filter element assembly 300 is connected to the raw water chamber 221 through the water pump 400, and the output end of the filter element assembly 300 is connected to a drainage pipe 500 that discharges water toward the clean water chamber 211; the sensing device 600 is arranged between the container assembly 200 and the kettle body 100, and can sense the water discharged from the raw water chamber 221 toward the water pump 400; the control unit assembly 700 is arranged in the kettle body 100, and is electrically connected to the sensing device 600 and the water pump 400.

[0028] When the raw water chamber 221 of the container assembly 200 contains water to be filtered, after the container assembly 200 is placed on the kettle body 100, the sensing device 600 can sense the water discharged from the raw water chamber 221 toward the water pump 400, and transmit the signal to the control unit assembly 700, and the control unit assembly 700 controls the water pump 400 to work, and transports the water to be filtered to the filter element assembly 300, and the water is discharged into the clean water chamber 211 after the filtering action of the filter element assembly 300, so as to be drunk by the user. The internal and external layered filtering kettle of the above structure isolates the water to be filtered and the filtered water, and uses the cooperation of the sensing device 600, the water pump 400 and the filter element assembly 300 to automatically and quickly filter the water, thereby improving the water filtering efficiency, and the sensing device 600 controls the water pump 400 to work only after sensing that the water can be discharged from the raw water chamber 221, thereby avoiding the water pump 400 working in a waterless state and wasting the service life of the water pump 400. The volume of the purified water chamber 211 is greater than or equal to the volume of the raw water chamber 221 to prevent the filtered water from overflowing.

[0029] See also Figure 3 and Figure 4 In some embodiments of the present invention, the input end of the water pump 400 is connected to a water receiving pipe 410, and the end of the water receiving pipe 410 away from the water pump 400 is connected to a transfer connector 800, and the transfer connector 800 is provided with a transfer cavity 810 that can connect the raw water cavity 221 with the water pump 400; the sensing device 600 includes a first conductive sheet 610 and a second conductive sheet 620 that are arranged on the transfer connector 800 and extend into the transfer cavity 810, and the control unit component 700 is provided with a detection circuit whose two ends are electrically connected to the first conductive sheet 610 and the second conductive sheet 620 respectively. When the water in the raw water chamber 221 flows into the transfer chamber 810, since the unfiltered water is a conductor, the two ends of the detection circuit can be connected through the first conductive sheet 610, the unfiltered water and the second conductive sheet 620. After the detection circuit is connected, the signal is transmitted to the control unit component 700, and the control unit component 700 controls the water pump 400 to start, so as to avoid the water pump 400 working in a waterless state and shortening the service life of the water pump 400.

[0030] See also Figure 3 and Figure 4In some embodiments of the present invention, when the container assembly 200 is not mounted on the kettle body 100, in order to ensure that the water in the raw water chamber 221 does not leak, a water outlet connected to the raw water chamber 221 is provided at the bottom of the inner shell 220, and a valve stem 223 is movably provided on the water outlet, and a sealing member 224 is provided on the upper part of the valve stem 223.
