[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model provides a technical solution: a mixer connecting seat assembly, including a mixing tank 1, a through-hole 11 at the top of the mixing tank 1, a connecting seat body 12 inside the through-hole 11, a sealing component between the connecting seat body 12 and the mixing tank 1, and a fastening component between the connecting seat body 12 and the mixing tank 1. The sealing component includes an annular groove 21 at the top of the through-hole 11, a first sealing gasket 22 fixedly connected to the bottom of the connecting seat body 12, a plurality of extrusion grooves 23 arranged circumferentially at the top of the annular groove 21, and an extrusion rod 24 disposed in the extrusion grooves 23. The system consists of a spring 25 fixedly connected to the bottom of the extrusion rod 24, an extrusion plate 26 fixedly connected to the top of the extrusion rod 24, and a second sealing gasket 27 fixedly connected to the top of the extrusion plate 26. The extrusion rod 24 is slidably connected to the extrusion groove 23. The connecting seat can be inserted into the through-hole 11. The first sealing gasket 22 can contact the second sealing gasket 27 and compress the second sealing gasket 27 to deform it. The second sealing gasket 27 can drive the extrusion plate 26 to move, which in turn can drive the extrusion rod 24 to move, which in turn can compress the spring 25 to deform it. The thrust generated by the deformation of the spring 25 can push the second sealing gasket 27 to move. The sealing gasket 27 fits tightly with the first sealing gasket 22, improving sealing performance and preventing leakage. A sealing groove 41 is provided on one side of the top of the through-hole 11. A third sealing gasket 42 is fixedly connected to the bottom of the connecting seat body 12. Both the sealing groove 41 and the third sealing gasket 42 have trapezoidal cross-sectional shapes, allowing the third sealing gasket 42 to be inserted into the sealing groove 41. The trapezoidal shape of the sealing groove 41 and the third sealing gasket 42 increases the contact area, further improving sealing performance. An installation port 51 is provided on the inner wall of the through-hole 11, and the inner wall of the installation port 51 is fixedly connected to... There is a fourth sealing gasket 52, which can seal the inner wall of the opening 11 and further improve the sealing performance. Two elastic frames 61 are fixedly connected to the bottom of the extrusion plate 26 along the axis of the extrusion rod 24. The bottom of the elastic frame 61 is fixedly connected to the bottom of the extrusion groove 23. The two sides of the elastic frame 61 are arc-shaped. When the extrusion plate 26 moves, it can also drive the elastic frame 61 to deform. The thrust generated by the deformation of the elastic frame 61 can further increase the extrusion force on the second sealing gasket 27, making it fit more tightly with the first sealing gasket 22, and further improving the sealing performance.

[0025] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5The fastening components include screws 31 fixedly connected to the top periphery of the mixing tank 1, connecting plates 32 fixedly connected to the periphery of the connecting seat body 12, a connecting port 33 opened on the top of the connecting plate 32, a first nut 34 connected to the outside of the screws 31, and a second nut 35 connected to the outside of the screws 31 and located above the first nut 34. The first nut 34 and the second nut 35 are both screwed to the screws 31. The screws 31 are inserted into the connecting port 33. When the connecting seat body 12 is inserted into the through port 11, the screws 31 are also inserted into the connecting port 33. The first nut 34 and the second nut 35 can be screwed onto the screws 31, which can fix the connecting plate 32 and thus tighten the connecting seat body 12. The connection body 12 is tightly fixed to prevent displacement and improve working stability. The top of the mixing tank 1 has positioning grooves 71 on both sides, and the bottom of the connection body 12 has positioning rods 72 fixedly connected to both sides. The positioning rods 72 are inserted into the positioning grooves 71 and can be vertically inserted into the positioning grooves 71 to limit the horizontal movement of the connection body 12 and prevent horizontal movement. This further improves the stability of the connection body 12. The top of the connection body 12 has four mounting holes 81, which are evenly distributed along the axis of the connection body 12. The mounting holes 81 facilitate the fixing of the motor to the connection body 12.

[0026] Working principle: During operation, the main body 12 of the connector is inserted into the through-hole 11, the positioning rod 72 is simultaneously inserted into the positioning groove 71, and the screw 31 is inserted into the connector 33. The first sealing gasket 22 can contact the second sealing gasket 27 and compress the second sealing gasket 27 to deform it. The second sealing gasket 27 can drive the compression plate 26 to move, which in turn can drive the compression rod 24 to move, which in turn can compress the spring 25 and the elastic frame 61 to deform it. The thrust generated by the deformation of the spring 25 and the elastic frame 61 can push the second sealing gasket 27 to fit tightly against the first sealing gasket 22, which can improve the sealing performance. Meanwhile, the third sealing gasket 42 can be inserted into the sealing groove 41 to further improve the sealing performance and prevent material leakage. Then, the first nut 34 and the second nut 35 are screwed onto the outside of the screw 31, so that the connecting seat body 12 can be tightly connected and fixed to the mixing tank 1, which can prevent the connecting seat body 12 from shaking. Then, the motor can be fixed to the connecting seat body 12 through the mounting hole 81. The above is the working process of the whole device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.
