The driving part 110 is in transmission connection with the permanent magnet 107 through the transmission mechanism 120, and the permanent magnet 107 is driven in a labor-saving manner by the combined action of the driving part 110 and the transmission mechanism 120.
The transmission mechanism can be a labor-saving structure, and the driving part drives the labor-saving transmission mechanism to realize labor-saving driving.
The transmission mechanism 120 is a gear transmission mechanism 120, a chain transmission mechanism or a belt transmission mechanism, and the driving part 110 is in meshing transmission with the gear transmission mechanism 120, or is in chain connection with the chain transmission mechanism or is in belt connection with the belt transmission mechanism, so as to drive the permanent magnet 107 to rotate.
The following explains the case where the gear mechanism 120 is the transmission mechanism 120.
As shown in fig. 1 and fig. 11, the transmission mechanism 120 is a gear transmission mechanism 120, the driving member 110 has a meshing portion 111 meshed with the gear transmission mechanism 120, the permanent magnet 107 is connected to the gear transmission mechanism 120 through a rotating shaft, and the driving member 110 drives the gear transmission mechanism 120 to rotate through the meshing portion 111 to drive the permanent magnet 107 to rotate.
Wherein, drive component 110 is manual drive component, for example drives the handle, has reduced electric drive component 110's use, and more the cost-effective has reduced the power consumption danger moreover.
The gear transmission mechanism 120 has a simple structure, and is more stable than a jaw closing structure; and the gear transmission mechanism 120 is not easy to damage even if used for a long time, the possibility of generating noise in the washing process due to looseness generated in long-term use is reduced, and the gear transmission mechanism 120 is connected with the driving part 110 in a matching way, so that the occupied space is small, the realization is convenient and the cost is low.
Further, the engaging portion 111 is arc-shaped, the gear teeth engaged with the gear transmission mechanism 120 are disposed on the inner side of the arc, and the driving member 110 is connected with the gear transmission mechanism 120 through the arc-shaped engaging portion 111 to achieve labor-saving driving of the permanent magnet 107.
Compared with the direct adjusting permanent magnet 107, the structure of the invention is more labor-saving and more stable through the matching of the meshing part 111 of the driving part 110 and the gear transmission mechanism 120.
Specifically, the following structure is possible.
In the first scheme, the gear transmission mechanism 120 is a multi-stage gear transmission mechanism 120 and comprises a plurality of transmission gears in meshing transmission, the meshing part 111 is meshed with one of the transmission gears, the permanent magnet 107 is connected with the other transmission gear through the rotating shaft 108, and the diameter of the circle where the arc-shaped meshing part 111 is located is larger than that of the transmission gear.
Utilize the diameter of the circle in curved meshing portion 111 place to be greater than drive gear's diameter, make drive unit 110 rotate less angle, can realize that permanent magnet 107 rotates 90, on the one hand, the drive is more laborsaving, reduces the space and shows, and the user need not drive the wide-angle rotation hard, and on the other hand is convenient for the user application of force, and user's experience feels better.
In a second scheme, the gear transmission mechanism 120 includes a transmission gear connected with the permanent magnet 107 through the rotating shaft 108, the meshing portion 111 is in meshing transmission with the transmission gear, the diameter of the circle where the arc-shaped meshing portion 111 is located is larger than that of the transmission gear, and the driving part 110 rotates by a smaller angle, that is, the permanent magnet 107 rotates by 90 °.
Compared with the driving through the multistage gear transmission mechanism 120, if the permanent magnet 107 reaches the same rotation angle, the diameter difference of the two gears in the second scheme is larger, and the two gears are in transmission connection through the multistage gear transmission mechanism 120, the diameter difference of the transmission gears is reduced by the plurality of transmission gears, and the transmission gears are not easy to damage.
Further, the permanent magnet 107 is in a long strip shape, a connecting line of an N pole and an S pole of the permanent magnet 107 is perpendicular to the rotating shaft 108, and an axis of the rotating shaft 108 simultaneously penetrates through the permanent magnet 107 and the center of a transmission gear connected with the rotating shaft 108.

Due to the labor-saving structure formed by the labor-saving driving part and the gear transmission mechanism, the driving part 110 rotates by a smaller angle, and the permanent magnet 107 can rotate by 90 degrees. Because the rotation angle of the driving part does not exceed 90 degrees, the driving part is designed into a section of circular arc, the length of the meshing part 111 is reduced, and the production cost is reduced.
Further, the driving body 119 is connected with the cover body 100 through a pin 122, the gear transmission mechanism 120 is arranged on the outer wall of the housing 103, the driving block 118 is arranged on the driving body 119 and corresponds to the gear transmission mechanism 120, and the circle center of the circular arc-shaped side wall on the driving block 118 is collinear with the axis of the pin 122. By utilizing the coaxial rotation of the arc-shaped side surfaces of the driving body 119 and the driving part, when a user drives the driving body 119, the driving part and the driving body 119 rotate coaxially to drive the gear transmission mechanism 120 to rotate, so as to drive the permanent magnet 107 to rotate.
Further, as shown in fig. 8, in a schematic view of one side of the structure, two sides of the permanent magnet 107 are respectively provided with a rotating shaft 108 for driving the permanent magnet 107 to rotate, the two rotating shafts 108 for driving the permanent magnet 107 to rotate respectively penetrate through circular openings at two cylindrical ends of the closed loop and are respectively in transmission connection with a gear transmission mechanism 120, and the gear transmission mechanisms 120 at two sides rotate at the same speed to drive the permanent magnet 107 to rotate together.
The rotating shafts 108 on the two sides of the permanent magnet 107 and the gear transmission mechanism 120 connected with the rotating shafts 108 are utilized, so that the permanent magnet 107 can rotate more easily and stably, gear abrasion is reduced, the permanent magnet 107 is not prone to being deviated and clamped in a closed loop, and the service life is longer.
Further, as shown in fig. 4-8, the driving body 119 has an inner cavity 114 with a downward opening 115, the driving body 119 buckles the housing 103 under the inner cavity 114, the gear transmission mechanism 120 is located on an outer wall of the housing 103, and the driving blocks 118 are disposed on an inner wall of the inner cavity 114 and respectively opposite to the gear transmission mechanism 120.
