The rotating shaft 500 penetrates through the upper end surface of the housing 400, and the lower end of the rotating shaft 500 extends into the housing 400 and is close to the bottom of the housing 400. The first fan blade assembly 100, the second fan blade assembly 200 and the third fan blade assembly 300 are sequentially arranged along a top-down direction in fig. 3, the first fan blade assembly 100 and the rotating shaft 500 rotate synchronously and can axially slide relative to the rotating shaft 500, and the third fan blade assembly 300 is fixedly connected to the lower end of the rotating shaft 500.

Specifically, when the second blade assembly 200 slides upward to be close to or in contact with the first blade assembly 100, it is switched to slide downward; when the second blade assembly slides down to approach or contact the third blade assembly 300, it switches to sliding up.

As shown in fig. 5 and 8, the outer circumferential wall surface of the rotating shaft 500 is provided with a rising screw 510 and a falling screw 520, and the rising screw 510 and the falling screw 520 have the same pitch and are rotated in opposite directions. The staggered position of the ascending screw thread 510 and the descending screw thread 520 from bottom to top is a first staggered position and a second staggered position … … Nth staggered position in sequence, besides the first staggered position, a guide arc 540 is arranged at the lower side of the staggered position of the ascending screw thread 510 and the descending screw thread 520, the radial depth of the guide arc 540 along the rotating shaft 500 is smaller than that of the ascending screw thread 510 or the descending screw thread 520 along the rotating shaft 500, and a boss is left below the guide arc 540.

As shown in fig. 2 to 4, the rotating shaft 500 is further provided with a plurality of mounting holes, the mounting holes are uniformly distributed along the axial direction of the rotating shaft 500, and the distance between two adjacent mounting holes is equal to the thread pitch of the lifting thread 510. An elastic stop block 530 is arranged in each mounting hole, one end of the elastic stop block 530 protrudes out of the mounting hole, the protruding end of the elastic stop block 530 is arranged in an arc shape, and when the protruding end of the elastic stop block 530 is pressed by force reaching a preset value, the elastic stop block 530 is completely retracted into the mounting hole.

As shown in fig. 9, the first fan blade assembly 100 includes a first mounting ring 120, a plurality of first blades, a blocking ring 114 and a floating rod assembly 112, the first mounting ring 120 is sleeved on the rotating shaft 500, the plurality of first blades are fixedly connected to the outer peripheral wall surface of the first mounting ring 120, the floating rod assembly 112 is fixedly connected to the upper end surface of the first mounting ring 120, and the blocking ring 114 is fixedly connected to the floating rod assembly 112 and located above the first mounting ring 120. The density of floating rod assembly 112 is relatively low, and when first fan blade assembly 100 is submerged in the liquid to be stirred, the upward buoyancy is primarily provided by floating rod assembly 112. The distance between the upper end surface of the retainer ring 114 and the lower end surface of the first mounting ring 120 is equal to the pitch of the raised threads 510, i.e., the distance between the two resilient stoppers 530. The intersection of the inner peripheral wall surface and the lower end surface of the first mounting ring 120 is provided with a guide groove 122, and since the first mounting ring 120 and the rotating shaft 500 are not relatively rotatable, the position of the guide groove 122 is kept relatively fixed with the rotating shaft 500 along the circumferential direction, and the guide groove 122 is arranged near the position where the ascending screw 510 and the descending screw 520 are staggered and provided with a guide circular arc 540. The elastic stoppers 530 are a first elastic stopper 530, a second elastic stopper 530 … … and an Nth elastic stopper 530 from bottom to top.

The second blade assembly 200 includes a second mounting ring sleeved on the rotation shaft 500, a guide unit 210 fixedly connected to an inner peripheral wall surface of the second mounting ring, and a plurality of second blades, wherein the guide unit 210 is disposed in the ascending screw 510 and/or the descending screw 520. When the external driving device drives the second mounting ring to rotate relative to the rotating shaft 500, the guide unit 210 is located in the ascending screw 510 and/or the descending screw 520, and thus the second mounting ring is driven to slide up and down along the axial direction of the rotating shaft 500. The plurality of second blades are fixedly connected to the peripheral wall surface of the second mounting ring, and the angles of the second blades are adjustable, so that the second blades drive the liquid to be stirred to flow from bottom to top or from top to bottom.

As shown in fig. 10, the guide unit 210 includes a front guide column 211, a middle guide column 212, and a rear guide column 213, each of the front guide column 211, the middle guide column 212, and the rear guide column 213 includes an upper section and a lower section, diameters of the upper section of the front guide column 211, the upper section of the middle guide column 212, and the lower section of the rear guide column 213 are the same, diameters of the lower section of the front guide column 211, the lower section of the middle guide column 212, and the upper section of the rear guide column 213 are the same, and a diameter of the upper section of the front guide column 211 is larger than a diameter of the lower section of the front guide column 211.

In an initial state, the rotating shaft 500 does not rotate, the first blade assembly 100, the second blade assembly 200 and the third blade assembly 300 are all located at the lower end of the rotating shaft 500, the second blade assembly 200 is located between the first intersection and the second intersection, the first blade assembly 100 is located between the first elastic stopper 530 and the second elastic stopper 530, the lower end surface of the first mounting ring 120 abuts against the first elastic stopper 530 and cannot move down under the limitation of the first elastic stopper 530, and the upper end surface of the retaining ring 114 is close to or abuts against the second elastic stopper 530. Injecting a liquid to be stirred into the stirring cavity, wherein when the liquid to be stirred submerges the first mounting ring 120, the buoyancy force applied to the first fan blade assembly 100 is not enough to make the first fan blade assembly 100 float upward and push the second elastic stopper 530 to contract the rotating shaft 500, and at this time, the first fan blade assembly 100 does not move axially; when the liquid to be stirred submerges the first mounting ring 120 and submerges the floating rod group 112 with a length larger than the preset length (at this time, the liquid to be stirred is at least located above the retaining ring 114, and usually, the liquid to be stirred is located above the third elastic stopper 530 at this time), the buoyancy applied to the first fan blade assembly 100 makes the first fan blade assembly 100 float upward and pushes the second elastic stopper 530 to contract the rotating shaft 500, at this time, the first fan blade assembly 100 is no longer stopped by the second elastic stopper 530 and slides upward, and during the upward sliding process, the buoyancy applied to the first fan blade assembly 100 is gradually reduced and still can make the first fan blade assembly 100 slide upward; until the retaining ring 114 abuts against the third elastic stop 530, the upward buoyancy of the first blade assembly 100 is not enough to push the third elastic stop 530 to retract the rotating shaft 500, and simultaneously the first mounting ring 120 floats above the second elastic stop 530, and the second elastic stop 530 extends, so that the first blade assembly 100 stays between the second elastic stop 530 and the third elastic stop 530. Therefore, the first fan blade assembly 100 is lifted in a step-like manner, that is, the first fan blade assembly 100 can only stay at the preset position for a long time, but cannot stay at any position in the axial direction of the rotating shaft 500 for a long time. The step-down process and the step-up process of the first blade assembly 100 are just opposite, and are not described herein again. In short, by providing the step-floating mechanism, the first fan blade assembly 100 is located at a specific point position when the first fan blade assembly 100 receives a certain interval of buoyancy.

The movement of the second blade assembly 200 will be described by taking the upper portion of the first blade assembly 100 abutting against the fourth elastic stop 530 as an example. The second mounting ring is rotated by the external driving device, the guiding unit 210 is located in the ascending screw 510, and the second fan blade assembly 200 moves upward from the first intersection. When the second fan blade assembly 200 moves to the second intersection, the front guide post 211 first enters the second intersection, and since the middle guide post 212 and the rear guide post 213 are still located in the lifting threads 510 below the second intersection, the front guide post 211 still moves in the spiral direction of the lifting threads 510 under the action of the coil spring 214 until the front guide post 211 moves into the lifting threads 510 above the second intersection. When the front guide post 211 is located in the ascending thread 510 above the second intersection, the middle guide post 212 is located in the second intersection, and the rear guide post 213 is located in the ascending thread 510 below the second intersection, at this time, since the front guide post 211 and the rear guide post 213 are both located in the ascending thread 510, the middle guide post 212 still moves along the spiral direction of the ascending thread 510 under the action of the coil spring 214 until the middle guide post 212 moves into the ascending thread 510 above the second intersection. Thereafter, since the front guide post 211 and the middle guide post 212 are both located within the raised thread 510, the rear guide post 213 is still moved in the helical direction of the raised thread 510 by the coil spring 214 until the rear guide post 213 moves into the raised thread 510 above the second intersection. Therefore, the guiding unit 210 can smoothly pass through the intersection of the ascending screw 510 and the descending screw 520 far away from the first fan blade assembly 100, and no missteering occurs.

When second blade assembly 200 moves closer to first blade assembly 100, guide unit 210 enters a third intersection. Specifically, the front guide pillar 211 firstly enters the third intersection, and the upper section of the front guide pillar 211 abuts against the guide groove 122 on the first mounting ring 120 and the guide arc 540 in the third intersection at the same time, so that the front guide pillar 211 can smoothly turn and move from the ascending thread 510 to the descending thread 520; then the middle guide post 212 enters the third intersection, and the upper section of the middle guide post 212 abuts against the guide groove 122 on the first mounting ring 120 and the guide arc 540 in the third intersection at the same time, so that the middle guide post 212 can smoothly turn and move from the ascending thread 510 to the descending thread 520; finally, the trailing guide leg 213 enters the third intersection, the upper section of the trailing guide leg 213 is smaller in size and does not contact the guide slot 122 on the first mounting ring 120 and the guide arc 540 in the third intersection, and the trailing guide leg 213 follows the leading guide leg 211 and the middle guide leg 212 into the lowering thread 520 under the action of the coil spring 214 after entering the third intersection. Thus, the direction of guide unit 210 is reversed at the intersection of ascending thread 510 and descending thread 520 near first fan blade assembly 100.

It should be noted that the elastic force of the first elastic block 530 should be greater than that of the first elastic block 530, so that the first blade assembly 100 cannot push the first elastic block 530, thereby limiting the lower limit position of the first blade assembly 100. The first intersection is a smooth curve, and the first intersection is provided with the ascending screw 510 and the descending screw 520 only at the upper part, and is not provided with the ascending screw 510 and the descending screw 520 at the lower part, i.e. the first intersection only performs a reversing function and cannot allow the guide unit 210 to pass through.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
