As will be readily understood, when the first and

second magnets

4 and 19 are relatively moved, the first and second

annular portions

601 and 602 are also relatively moved, so that the basket 6 is folded and its height is lowered. When the filler is replaced, after the first sliding block 301 moves to the top of the first electric guide rail 3, the second sliding block 1801 continues to move upwards along the second electric guide rail 18, so that the second annular part 602 moves towards the first annular part 601, the basket body 6 is folded, the filler therein is exposed, and the filler replacement is more convenient.

In addition, the filter chamber also comprises a timer and an alarm, wherein the timer is in signal connection with the controller, and the controller is connected with the alarm through a control circuit. When the filler is replaced by a worker, the countdown can be set through the timer according to the replacement period of the filler, when the timer finishes counting, a signal is sent to the controller, and the controller starts the alarm to prompt the worker to replace the filler in time after receiving the signal sent by the timer. The timer and the alarm can be of known types in the market.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
