Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

According to the description of fig. 1-7:

a non-contact torque transmitting structure comprising:

the cup body 1 comprises a fit ring 11, a conduction pressing block 12 and a cutter mounting hole 13, wherein the fit ring 11 comprises fit heads 111 respectively arranged on the inner sides, the conduction pressing block 12 is arranged at the top end of the fit ring 11, the cutter mounting hole 13 is arranged at the top end of the conduction pressing block 12 and comprises a PNP proximity switch placing hole 131 arranged on the outer side;

the upper torque cutter 2 is arranged in the cutter mounting hole 13 and comprises a shaft sleeve 21, a bearing 22 and an upper cutter core 23 which are arranged from outside to inside, the shaft sleeve 21 comprises a shaft sleeve sealing head 211, a shaft sleeve engaging ring piece 212 and a shaft sleeve engaging hook 213 which are arranged from top to bottom, the upper cutter core 23 comprises an upper cutter sealing cover 231 and an upper torque rotor 232 which are arranged from top to bottom, the upper torque rotor 232 comprises an upper strong magnet set 2321 and a light reflecting patch 2322, the upper strong magnet set 2321 is respectively arranged in the upper torque rotor 232, and the light reflecting patch 2322 is respectively attached to the top surface end of the upper torque rotor 232;

a PNP proximity switch 3 provided in the PNP proximity switch placement hole 131, and including a proximity switch seal ring 31 provided around the outside;

the base mechanism 4 is arranged at the bottom of the cup body 1 and comprises a base fit concave ring 41, a conduction seat 42 and a lower torque mounting hole 43, the base fit concave ring 41 comprises base fit heads 411 respectively arranged at the top, the conduction seat 42 is arranged at the top end of the base fit concave ring 41, and the lower torque mounting hole 43 is arranged at the center of the base fit concave ring 41;

the lower torque rotor mechanism 5 is arranged in the lower torque mounting hole 43 and comprises a lower torque rotor 51 and a driving mechanism 52 which are arranged from top to bottom, and the lower torque rotor 51 comprises lower strong magnets 511 which are respectively arranged inside.

Because the corresponding polarities of the lower strong magnet set 511 and the upper strong magnet set 2321 are opposite, the magnets in the lower strong magnet set 511 are attracted to each other, and the magnets in the upper strong magnet set 2321 are attracted to each other, when a user uses the invention, the cup body 1 and the base mechanism 4 are matched and sealed, and the user clicks to drive to use, the lower torque rotor 51 is driven to rotate by the driving mechanism 52, the upper torque cutter 2 rotates along the rotating direction of the lower torque rotor 51 under the opposite mutual repulsion of the magnetism of the upper and lower magnetic sets, so that the lower torque rotor 51 provides kinetic energy for the driving shaft to rotate by the driving mechanism 52, the upper torque rotor 232 is a driven shaft, when the driving shaft rotates, the driven shaft is driven to rotate by the repulsion force generated by the strong magnets on the upper and lower torque rotors, and the non-contact torque transmission is realized, and the maximum advantage is that when the load exceeds the limit, the driving shaft and the driven shaft can slip without burning out the motor, the problems of abrasion, heating and the like can be avoided when the torque is transferred by the gear, the assembly and the disassembly are convenient, and the gear-type torque transmission device can be widely applied to small household appliances such as wall breaking machines and crushers.

Because the retro-reflective patch 2322 is sensed by the PNP proximity switch 3, when the user uses the present invention, after the lower torque rotor 51 is driven to rotate by the driving mechanism 52, the upper torque rotor 232 is driven to rotate by repulsive force, so that the PNP proximity switch 3 can continuously sense the signal of the rotation driving of the upper torque rotor 232 by the sensing light reflecting patch 2322, and feeds back to the external control panel in real time, and when the driving mechanism 52 drives the lower torque rotor 51 to rotate and the PNP proximity switch 3 does not sense a signal, the information is fed back to an external control panel in real time, an idle running signal of the invention is sent to a user, the user can observe whether foreign matters in the cup body 1 block the rotation of the upper torque rotor 232 or whether the quality problem of the upper torque rotor 232 occurs, the PNP proximity switch 3 signal may be E2E-X2F1-Z of an ohilon.

Because the base conjunction head 411 is matched with the conjunction head 111, the conjunction head 111 comprises a limiting head 1111 arranged at the outer end respectively, the base conjunction head 411 is limited by the limiting head 1111, and the conduction pressing block 12 is matched with the conduction seat 42, when a user uses the cup body conduction device, the cup body 1 and the base mechanism 4 can be closely matched and connected together through twisting through matching, and when the cup body 1 is connected with the top of the base mechanism 4 through twisting, the connection failure caused by too much twisting connection position can be prevented through the limiting of the limiting head 1111, and the tight conduction connection between the conduction pressing block 12 and the conduction seat 42 can be realized through limiting.

Because the shaft sleeve matching ring piece 212 comprises a matching ring piece sealing ring 2121 arranged at the bottom end, the shaft sleeve matching ring piece 212 abuts against the top of the cutter mounting hole 13 through the matching ring piece sealing ring 2121, the shaft sleeve matching hook 213 abuts against the bottom of the cutter mounting hole 13, and the diameter of the shaft sleeve matching ring piece 212 is equal to that of the cutter mounting hole 13, when a user uses the tool mounting structure, the shaft sleeve 21 is tightly arranged in the cutter mounting hole 13 through the abutment of the shaft sleeve 21 against the top and the bottom of the cutter mounting hole 13, and when the shaft sleeve 21 is in abutting connection in the cutter mounting hole 13, the sealing performance of the connecting structure is realized through the use of the sealing ring.

Because the shaft sleeve sealing head 211 is matched with the upper cutter sealing cover 231, and the shaft sleeve 21 and the bearing 22 are made of high-temperature-resistant PPS or ceramics, when a user uses the cup, the shaft sleeve 21, the bearing 22 and the upper cutter core 23 can be in sealing connection through matching, liquid in the cup body 1 can be prevented from permeating through a connecting gap between the shaft sleeve 21 and the bearing 22 and the upper cutter core 23 to damage internal elements, the high-temperature-resistant PPS is novel high-performance thermoplastic resin and has the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame retardancy, good thermal stability, excellent electrical property and the like, so when the user uses the shaft sleeve 21 and the bearing 22 which are made of PPS materials, the phenomenon that the shaft sleeve 21 and the bearing 22 are melted by heat during high-speed operation of a cutter can be prevented, and the normal use of the cup is influenced, and the ceramics have high-toughness, The cutter has the advantages of high bending strength, high wear resistance, excellent heat insulation performance, thermal expansion coefficient close to that of steel and the like, so that when a user uses the shaft sleeve 21 and the bearing 22 which are made of ceramic materials, the phenomenon that the shaft sleeve 21 and the bearing 22 are melted by heat when the cutter runs at high speed can be prevented, and the normal use of the cutter is influenced.
