[0044] When the liquid in the storage part 2 needs to be replaced, the driving motor 301 is started to drive the driving screw 302 to rotate, the rotation of the driving screw 302 can drive the driving seat 303 to move vertically in the installation shell 1, so that the driving seat 303 can first drive the fixed cover 306 to move upward and separate from the storage part 2, so that the storage part 2 loses the extrusion of the fixed cover 306 and is self-sealed, and at the same time the driving seat 303 can extrude the blocking part 4, so that the blocking part 4 extrudes and seals the communication between the blocking drainage pipe and the storage part 2, and as the driving seat 303 continues to move, the driving seat 303 can extrude the rotating seat 305, so that the rotating seat 305 rotates to drive the storage part 2 to extend out of the inside of the installation shell 1, thereby facilitating the replacement of the storage part 2.

[0047] The limiting groove 3041 provides guidance and limiting for the rotation of the rotating seat 305, ensuring the stability of the rotating seat 305 when rotating.

[0048] Please refer to Figure 6 As shown in the figure, the lower end of the driving seat 303 is provided with an extrusion groove 3031, the extrusion groove 3031 cooperates with the limiting groove 3041, the inside of the extrusion groove 3031 is provided with a vertical locking section and an inclined extrusion section;

[0049] When the rotating seat 305 needs to extend out of the inside of the installation shell 1, the upper end of the rotating seat 305 is at the upper end of the locking section of the extrusion groove 3031, and in the process of upward movement of the driving seat 303, the rotating seat 305 is in a stationary state due to the fact that the rotating seat 305 is inside the locking section of the extrusion groove 3031, and at the same time, the fixed cover 306 can be separated from the storage part 2 due to the upward movement of the driving seat 303;

[0050] With the continuous movement of the driving seat 303, the upper end of the rotating seat 305 enters the inside of the extrusion section of the extrusion groove 3031, so that the extrusion section extrudes the upper end of the rotating seat 305, causing the rotating seat 305 to rotate in the inside of the installation shell 1 to extend out, thereby completing the extension of the rotating seat 305 in the inside of the installation shell 1;

[0051] When the rotating seat 305 needs to retract into the inside of the installation shell 1, through the reverse movement of the driving seat 303, the extrusion section of the extrusion groove 3031 first extrudes the rotating seat 305, so that the rotating seat 305 gradually rotates into the inside of the installation shell 1, so that the storage part 2 in the inside of the rotating seat 305 vertically corresponds to the fixed cover 306, with the continuous movement of the rotating seat 305, the upper end of the rotating seat 305 enters the inside of the extrusion groove 3031, so that the rotating seat 305 is in a stationary state, and at the same time, the fixed cover 306 is moved to the upper end of the storage part 2 by the rotating seat 305, so that the fixed cover 306 can be connected to the storage part 2, thereby completing the fixation of the storage part 2 by the fixed cover 306;

[0057] After the storage tank 201 is installed into the inside of the rotating seat 305, and the upper end of the storage tank 201 vertically corresponds to the fixed cover 306, after the fixed cover 306 is inserted into the upper end of the storage tank 201, the inside of the fixed cover 306 extrudes the closing plate 206, so that the closing plate 206 extrudes the connecting frame 204 to move downward, so that the upper end of the storage tank 201 loses the closure of the closing plate 206, the opening in the inside of the mounting seat 202 loses the blockage and closure of the closing ball 207, and the automatic opening of the storage part 2 is realized;

[0058] After the storage tank 201 is separated from the fixed cover 306, the elastic reset member 205 itself elastically restores to extrude the sliding column 203 to slide in the inside of the mounting seat 202, so that the sliding column 203 drives the connecting frame 204 and the closing plate 206 to move upward, until the closing plate 206 closes the opening in the upper end of the storage tank 201, and the sliding of the sliding column 203 can lift the closing ball 207 in the inside of the mounting seat 202, so that the closing ball 207 closes the inside of the mounting seat 202 to block the communication between the mounting seat 202 and the fixed cover 306, the automatic closure of the inside of the storage tank 201 is realized, and the leakage of the drainage liquid in the inside of the storage tank 201 is avoided;
