a concave part 221 is formed by downwards sinking the middle position of the top surface of the upper cover 22; an annular decorative plate 222 is arranged at the edge position of the top surface of the upper cover 22, so that the attractiveness is improved;

a through hole 231 penetrates through the middle position of the mounting seat 23 along the vertical direction; at least two guide grooves 232 extending radially outward from the edge of the through hole 231 are arranged on the mounting seat 23 at intervals along the circumferential direction of the through hole 231, and the bottom of each guide groove 232 is provided with a guide inclined surface 2321 gradually decreasing in the direction approaching the through hole 231; the mounting seat 23 is provided with an opening at the top of the guide groove 232, and the upper cover 22 at least partially covers the opening at the top of the mounting seat 23, so that the limiting block 5 is prevented from being separated from the guide groove 232 while the following limiting block 5 is conveniently mounted; in this embodiment, the mounting seat 23 and the base 21 share the same bottom wall, and are an integral component, thereby facilitating the processing.

The filter element 3 comprises a filter box 31 with an open top and a top cover 32 buckled on the top of the filter box 31.

The bottom end of the movable shaft 4 is connected to the middle position of the top cover 32 of the filter element 3, and the bottom end upwards passes through the through hole 231 of the mounting seat 23 and the upper cover 22 and is exposed out of the top surface of the upper cover 22. The peripheral wall of the movable shaft 4 is provided with at least two gear slots 41 arranged at intervals along the height direction. In the present embodiment, each shift position groove 41 is annular and is arranged on the peripheral wall of the movable shaft 4 in the circumferential direction of the movable shaft 4.

The number of the limiting blocks 5 corresponds to the number of the guide grooves 232, and the limiting blocks 5 are accommodated in the corresponding guide grooves 232, and due to the arrangement of the guide inclined surfaces 2321, the limiting blocks 5 always have a tendency to move toward the movable shaft 4 along the guide inclined surfaces 2321 under the action of gravity. In this embodiment, the stopper 5 is the ball form, and adopts the great material of density to make, and the diameter of stopper 5 is greater than the aperture of perforation 231 to avoid stopper 5 to drop through perforation 231.

Under the condition that the kettle cover 2 is fixed, the movable shaft 4 can move up and down relative to the kettle cover 2 under the action of external force, and under the condition that the gear grooves 41 with different heights of the movable shaft 4 move to the opposite sides of the limiting block 5, at least part of the limiting block 5 is inserted into the corresponding gear grooves 41, so that the filter element 3 is positioned at different heights relative to the kettle cover 2.

A handle 6 is mounted on the top end of the movable shaft 4 for holding by a user. As shown in fig. 2, the handle 6 is accommodated in the recess 221 of the upper cover 22 in a state where the stopper 5 is inserted in the shift position groove 41 located at the highest position.

The working principle of the embodiment is as follows:

(1) during installation, the movable shaft 4 is inserted into the through hole 231 in alignment, the limiting blocks 5 are placed in the corresponding guide grooves 232, the upper cover 22 is installed at the top of the base 21 to cover the top opening of the installation seat 23, and finally the lifting handle 6 and the filter element 3 are installed at the top end and the bottom end of the movable shaft 4 respectively;

(2) when the kettle is used, in an initial state, as shown in fig. 2, the limiting block 5 is inserted into the gear groove 41 at the highest position to achieve the effect of stopping up and down, so that the relative positioning between the kettle cover 2 and the movable shaft 4 is realized, a user holds the handle 6 and can drive the kettle cover 2 and the filter element 3 to synchronously move through the movable shaft 4, therefore, the filter element 3 only needs to be placed into the kettle body 1 in alignment with the opening 11 until the kettle cover 2 closes the opening 11, and then the kettle can be started by locking the outward extending elastic buckle 211;

in the working process of the kettle, when the concentration of tea water needs to be adjusted, a user only needs to hold the handle 6 to pull the movable shaft 4 upwards to drive the filter element 3 to rise (at the moment, the kettle body 1 and the kettle cover 2 are relatively fixed, and the total gravity of the two is relatively large, so that the reaction force of the movable shaft 4 can be overcome, and the filter element is prevented from moving along the movable shaft 4);

after the brewing is finished, the elastic buckle 211 is only required to be retracted for unlocking, and then the handle 6 is held to drive the kettle cover 2 and the filter element 3 to move upwards synchronously through the movable shaft 4, so that the opening of the opening 11 and the taking-out of the filter element 3 are synchronously realized.
