The driving magnetic wheel 21 is fixedly sleeved with the output end of the driving piece 1. The driven magnetic wheel 23 is fixedly sleeved with the screw 4 and is positioned on the flywheel 3.

Specifically, as shown in fig. 2, the magnetism isolating waterproof jacket 22 may be provided in a cylindrical structure having a built-in space.

The driven magnetic wheel 23 is located above the flywheel 3, and water is splashed into the driven magnetic wheel 23 during rotation of the flywheel 3. Because the driving magnetic wheel 21 is connected with the output end of the driving piece 1, the driving magnetic wheel 21 and the driven magnetic wheel 23 can be isolated through the arrangement of the magnetism isolating waterproof sleeve 22, so that the waterproof effect is achieved, water and electricity are isolated, and the safety is improved. Through the setting of magnetic drive subassembly 2, can realize shaftless transmission connection, waterproof magnetic force is as power transmission, and water and electricity keep apart.

In order to be favorable for avoiding water from entering the space where the driving magnetic wheel 21 is located, a first sealing ring 01 is sleeved on the outer side wall of the magnetism isolating waterproof sleeve 22, which is close to the direction of the driving magnetic wheel 21.

The second housing 232 encloses the second magnetic sheet 231. The second housing 232 is fixedly sleeved with the screw 4 and is positioned above the flywheel 3.

Specifically, as shown in fig. 2, since the magnetic isolation waterproof jacket 22 isolates the driving magnetic wheel 21 from the driven magnetic wheel 23, the first housing 212 may wrap the upper portion of the first magnetic sheet 211, exposing the lower portion of the first magnetic sheet 211. Since water can be splashed into the space where the driven magnetic wheel 23 is located, the second housing 232 completely encloses the second magnetic sheet 231, thereby playing a role in waterproofing the second magnetic sheet 231. The screw 4 is driven to rotate under the opposite suction torque force of the first magnetic sheet 211 and the second magnetic sheet 231.

The second housing 232 may be made of a waterproof and anti-corrosive food grade material since water can be splashed into the space where the driven magnetic wheel 23 is located.

The driving magnetic wheel 21 and the driven magnetic wheel 23 are respectively and correspondingly sleeved on the two anti-falling sleeves 24. One end of the fall preventing sleeve 24 is formed with a horizontally outwardly extending platform for abutting against the lower end surface of the driving magnetic wheel 21 or the upper end surface of the driven magnetic wheel 23, thereby preventing the axial movement of the driving magnetic wheel 21 and the driven magnetic wheel 23 due to the attraction between the driving magnetic wheel 21 and the driven magnetic wheel 23.

The anti-falling sleeve 24 can be made of sanitary and environment-friendly H62 copper materials as the anti-falling sleeve can be used for manufacturing drinking air-water mixed water.

Further, the screw 4 is rotatably mounted in the conduit 5 through a bearing assembly 6. The bearing assembly 6 is fixedly connected to the inner wall of the conduit 5 and is located between the magnetic drive assembly 2 and the flywheel 3. The lower end face of the magnetism isolating waterproof sleeve 22 abuts against the upper end face of the bearing assembly 6.

In particular, the bearing assembly 6 may include a bearing 61 and a bearing seat 62. The bearing 61 is sleeved on the upper part of the screw 4, and the bearing 61 is fixedly sleeved on the bearing seat 62. The outer wall of the bearing seat 62 is fixedly connected to the inner wall of the guide pipe 5, and the bearing seat 62 and the guide pipe 5 can be connected in an interference fit mode. In order to avoid the axial movement of the bearing seat 62 along the screw 4, the lower end surface of the magnetism isolating waterproof jacket 22 abuts against the upper end surface of the bearing seat 62.

Since water can splash into the bearing 61, the bearing 61 can be a ceramic bearing, so that oil-free lubrication, temperature resistance, friction resistance and corrosion resistance at high speed can be realized, and further sanitation can be realized. The ceramic bearing can also enable the noise to be less than or equal to 40db, the service life is 10000 hours or more when the ceramic bearing continuously works, and the indirect service time is 10 years or more.
