Detailed Description
For the filtering type air purifier, the tightness between the filter screen and related parts is a key factor influencing the performance of the whole purifier. The air purifier of cylindric filter screen all designs has the lifting disk structure to this filter screen oral area can be sealed with the fan air intake and laminate when guaranteeing the lifting disk to promote, makes the air that gets into the clarifier all can just get into the fan through the filter screen, thereby has guaranteed the complete machine performance.
As shown in fig. 1 to 3, the present invention provides a filter screen lifting structure, which comprises a lifting plate 2 disposed on a base 1 and an automatic lifting mechanism for driving the lifting plate 2 to lift, wherein the lifting plate can be lifted automatically as required, and the filter screen 3 is pushed or loosened by the lifting plate, so as to reduce the operation of a user, and facilitate the use. Automatic elevating system includes: the lifting disc can be driven to lift by the driving device, and the controller can control the stroke of the driving device for driving the lifting disc to lift, so that the lifting disc can be automatically lifted as required by the driving device. Wherein, drive arrangement includes: driving motor 4, drive block 5 and connecting block 6, drive block 5 drives rotatoryly through driving motor 4, and connecting block 6 sets up in 2 bottom surfaces of lifting disk to thereby it reciprocates to drive lifting disk 2 through 5 drives of drive block.
In one embodiment, the base 1 is provided with a groove 11 for installing the lifting disc 2, so that the lifting disc 2 can be retracted into the groove 11 or extend out of the groove 11, and can only move up and down and can not rotate in the groove 11, the bottom surface of the lifting disc 2 is provided with a circle of surrounding edge 21 capable of sheathing the side surface of the connecting block 6, so that the connecting block 6 can not rotate, the bottom surface of the connecting block 6 is provided with a threaded hole, and the driving block 5 is provided with a stud 51 matched with the threaded hole. In the specific lifting process, a rotating shaft of a driving motor 4 drives a driving block 5 to rotate in the forward direction, a stud 51 rotates in the threaded hole of a connecting block 6 in the forward direction, and the connecting block 6 cannot rotate and can only be driven to lift through the driving block 5, so that a lifting disc 2 is jacked to extend out of a groove to jack a filter screen 3 tightly; the rotating shaft of the driving motor 4 drives the driving block 5 to rotate reversely, the stud 51 can rotate reversely in the threaded hole of the connecting block 6 to drive the connecting block 6 to descend, so that the lifting disc 2 retracts into the groove 11 to loosen the filter screen 3, and the lifting disc can be driven to lift by the driving block, the connecting block and the driving motor.
The bottom surface of the groove 11 of the base 1 is also provided with a plurality of bayonets 13, the edge covering bottom of the lifting disc 2 is provided with a plurality of limit buckles 23, and the limit buckles 23 and the bayonets are buckled when the lifting disc 2 rises to a certain distance, so that the driving block 5 is prevented from being separated from the threaded hole of the connecting block 6. The thread at the upper end of the thread of the driving block or the thread at the thread hole of the connecting block can be removed, so that the connecting block is not matched with the thread and is still sleeved on the stud of the driving block when the connecting block is lifted to the maximum distance.
In the invention, a kidney-shaped hole is arranged on the driving block at the axis of the stud, and the end surface of the rotating shaft of the driving motor is matched with the kidney-shaped hole and is provided with a pair of parallel side surfaces, so that the rotating shaft of the driving motor can drive the driving block to rotate.
