[0002] The main function of the drive pump is pumping. The drive pump can also be called a pump or pumping. With the continuous advancement of technology, the demand for the use of drive pumps is also increasing.

[0003] Chinese patent application number: CN201810548092.5 provides a corrosion-resistant, sealless magnetic drive pump. This solution provides a bracket, a storage tank, a zinc block, a first wire, an external power supply, a second wire, a terminal and a front cover, so that the zinc block is connected to the negative pole of the power supply, and the front cover and the body part in contact with the front cover are connected to the positive pole of the power supply, so that the zinc block becomes the positive pole and the casing becomes the negative pole. Since the zinc block is more active, it will corrode instead of the casing, thereby sacrificing the anode to protect the cathode, thereby protecting the casing from corrosion. The metal casing can withstand liquids at higher temperatures.

[0004] Existing magnetic drive pumps have certain disadvantages when used. First, magnetic drive pumps have high requirements for sealing when used. The traditional magnetic drive pump has a single sealing and anti-leakage structure and cannot meet the use requirements. For this reason, we propose a leak-proof, seal-free magnetic drive pump.

[0037] The present invention will be described in further detail below with reference to the accompanying drawings.

[0040] The connecting mechanism 2 includes a sealing ring 201, which is sleeved on the outer end of the main body mechanism 1.

The movable component 2012 is slidably connected to the inner end of the sealing ring 201. The top of the sealing ring 201 is fixedly connected to a sealing rubber pad 202, and a reinforcing rib 203 is provided inside the main body mechanism 1.

[0041] Reference Figure 4-5 As shown, further, the reinforcing ribs 203 are evenly distributed, and the outer ends of the reinforcing ribs 203 are all provided with filling layers 204.

[0042] By installing the sealing ring 201 and cooperating with the sealing gasket 202 on the outside, a sealing structure can be formed at the inner end of the water outlet component 108, and when the sealing ring 201 is installed, the symmetrically distributed sealing sheets 2011 are adjusted and clamped on the inner end of the water outlet component 108 in conjunction with the movable component 2012 with adjustable position, so that the device has multiple sealing clamping structures, which effectively prevents water leakage and can effectively increase the anti-leakage effect of the magnetic drive pump. In addition, multiple reinforcing ribs 203 can increase the edge strength of the interface of the water outlet component 108, avoiding the water outlet component 108 from being more stable when connected to the external component, and will not cause the water outlet component 108 to deform due to the conduction of external force, affecting the pumping leakage of the magnetic drive pump.

[0043] Reference Figure 1-3 As shown, further, the main body mechanism 1 includes a motor 101, a driving magnet 102 is installed on the outer end of the motor 101, and a foot seat 103 is provided on the outer end of the driving magnet 102.

[0044] Reference Figure 1-2 As shown, further, a rear cover 104 is installed at the outer end of the foot seat 103 , and a sealing O-ring 105 is installed at the inner end of the rear cover 104 .

[0045] Reference Figure 1-2 As shown, further, a front cover 106 is installed at the outer end of the sealing O-ring 105, a water inlet 107 is installed at the front end of the front cover 106, and a water outlet assembly 108 is installed at the upper end of the front cover 106.

[0046] By installing the sealing O-ring 105, the rear cover 104 is connected to the external connection structure, while ensuring the stability of the connection between the rear cover 104 and the front cover 106, and effectively ensuring the sealing of the connection between the rear cover 104 and the magnetic drive pump.

[0047] Reference Figure 1 and Figure 6 As shown, further, the outer end of the water inlet 107 is slidably connected with a sealing member 301, and the sealing members 301 are symmetrically distributed.

[0048] Reference Figure 6 As shown, further, the outer ends of the sealing members 301 are fixedly connected to the movable rods 302 , and the outer ends of the movable rods 302 are sleeved with spring members 303 .

[0049] Reference Figure 6 As shown, further, the front side of the spring member 303 is slidably connected to a guide ring 304, the guide ring 304 is located at the outer end of the movable rod 302, the outer end of the guide ring 304 is slidably connected to a mounting bracket 305, and the inner end of the mounting bracket 305 is provided with a movable groove 306.

[0050] By installing symmetrically distributed semicircular seals 301 on the outside of the connection of the water inlet 107, the water inlet 107 can be more stable when connected to the external component to avoid leakage. When the water inlet 107 is connected to the external component, the movable rod 302 and the spring member 303 drive the seal 301 to adjust the position, allowing the seal 301 to easily adjust the position, making it convenient for the water inlet 107 to be connected to the external connection component. The seal 301 is easy to reset and can be easily snapped into the connection for sealing after installation is completed.

[0051] Specific implementation process: connect the water inlet 107 with the external component. When connected, the symmetrically distributed semicircular seal 301 is sleeved on the outside of the connection of the water inlet 107 to make the water inlet 107 more stable when connected to the external component. The symmetrically distributed sealing sheet 2011 cooperates with the movable component 2012 with adjustable position to adjust and clamp on the inner end of the water outlet component 108, so that the device has multiple sealing clamping structures. When the water inlet 107 is connected to the external component, the movable rod 302 and the spring component 303 drive the seal 301 to adjust the position, so that the seal 301 can easily adjust the position, which facilitates the water inlet 107 to cooperate with the external connection component for connection, and the seal 301 is easy to reset. After the installation is completed, it can be easily clamped at the connection for sealing.

[0052] When the water outlet component 108 is connected to the external connection component, the sealing ring 201 cooperates with the sealing gasket 202 on the outside to form a sealing structure at the inner end of the water outlet component 108, and cooperates with the assembly between the water outlet component 108 and the external connection component to effectively increase the leakage prevention effect of the magnetic drive pump. Multiple reinforcing ribs 203 can increase the edge strength of the interface of the water outlet component 108, thereby preventing the water outlet component 108 from being more stable when connected to the external component and will not be transmitted due to external forces. When the device is running, the sealing O-ring 105 is connected to the external connection structure due to the rear cover 104, while ensuring the stability of the connection between the rear cover 104 and the front cover 106, and effectively ensuring the sealing effect of the connection between the rear cover 104 and the magnetic drive pump.
