[0038] The present invention realizes the detachable of the agitator by arranging an agitator mounting assembly on the agitator, and enables the disassembly of the agitator to be completed without the aid of tools, making the disassembly operation of the agitator simple and facilitating the cleaning and maintenance of the agitator. The present invention will be introduced in detail below with reference to specific embodiments:

[0039] As Figure 1 、 Figure 2 shown, the present invention provides an agitator mounting assembly for detachably fixing an agitator on a drive shaft 30, including a clamping shaft 10 rotatably arranged on the agitator 20, and a clamping surface that can rotate with the clamping shaft 10 is arranged on the clamping shaft 10.

[0040] When the clamping surface rotates to the first position, it is clamped with the drive shaft 30 and is limited in the axial direction of the rotating shaft, so that the agitator 20 is fixed on the rotating shaft.

[0041] When the clamping surface rotates to the second position, it is separated from the drive shaft 30, and the agitator 20 can move axially along the drive shaft 30 and be separated from the drive shaft 30. Moreover, the clamping shaft 10 can be rotated manually without the aid of tools, which is convenient for users to operate.

[0042] Specifically, at least a part of the clamping shaft 10 is configured as a semi-circular shaft, that is, this part is configured as a semi-cylindrical structure, and its outer peripheral wall includes a plane and a cylindrical surface. The plane part of the semi-circular shaft constitutes the clamping surface. Correspondingly, a clamping groove 31 is arranged on the drive shaft 30. The clamping groove 31 is arranged at a position close to the upper end of the drive shaft 30 along a direction parallel to the radial direction of the drive shaft 30. Preferably, the wall surface of the clamping groove close to the end of the drive shaft 30 is a plane, which cooperates with the clamping surface, and the wall surfaces of other parts of the clamping groove 31 are arc surfaces, corresponding to the arc wall surface of the semi-circular shaft on the clamping shaft 10, so that the semi-circular shaft can rotate into the clamping groove 31, and the clamping surface abuts against the plane in the clamping groove 31 to complete the clamping.

[0043] Preferably, both ends of the clamping shaft 10 are connecting parts for the rotational connection of the clamping shaft 10, preferably constructed as a cylindrical structure to facilitate its rotation. Further, a lifting handle 11 is provided on the clamping shaft 10. The lifting handle 11 can drive the clamping shaft 10 to rotate. By pulling the lifting handle 11, the clamping surface can be rotated to the second position, and the pulsator 20 can be lifted by the lifting handle 11. By pushing the lifting handle 11, the clamping surface can be rotated to the first position.

[0044] Preferably, there are two clamping shafts 10, and the two clamping shafts 10 are arranged in parallel. The two clamping shafts 10 are respectively clamped on both sides of the drive shaft 30. When there are two clamping grooves 31 parallel to its diameter on the drive shaft 30, torque can be transmitted through the cooperation of the clamping grooves 31 and the clamping shafts 10, so that the drive shaft 30 drives the pulsator 20 to rotate.

[0045] The connecting part of the clamping shaft 10 is also used for connecting with the lifting wrench. Both ends of the lifting handle 11 are fixedly connected to the connecting part, and the middle part of the lifting handle 11 forms a lifting part. Preferably, the lifting handle 11 and the connecting part are connected by connecting pieces such as screws. Further, the position where the connecting part is connected to the lifting handle 11 is set as a non-cylindrical structure. For example, it includes two parallel planes, or a square structure, etc. The shape of the connecting position of the lifting handle 11 corresponds to it, so that the lifting handle 11 can better transmit torque to the clamping shaft 10.

[0046] The lifting part of the lifting handle 11 is connected to the connecting part through a bending structure. The bending structure makes the lifting part deviate towards the side of the connecting part, so that when the clamping surface rotates to the first position, a spacing is formed between the lifting part and the upper side surface of the pulsator 20, thereby providing an operating space for lifting the lifting part.

[0047] Preferably, it further includes a receiving member 40. An accommodating groove is formed inside the receiving member 40, and the clamping shaft 10 is rotatably arranged in the accommodating groove. The receiving member 40 is used for fixedly connecting with the pulsator 20. The receiving member 40 includes a bottom wall and a side wall. The bottom wall is used for fixedly connecting with the pulsator 20, and the side wall is arranged around the edge of the bottom wall. The bottom wall and the side wall enclose the accommodating groove. Further, the height of the side wall is higher than the height of the clamping shaft 10, so that the clamping shaft 10 can be completely embedded in the accommodating groove without affecting the normal operation of the pulsator 20.

[0048] Through holes are formed on the bottom wall of the receiving member 40 for corresponding setting with the mounting holes on the pulsator 20. Support ribs are also provided on the bottom wall, and the clamping shaft 10 is rotatably arranged on the support ribs.

[0049] Preferably, it further includes an end cap which can be closed onto the accommodating member 40. Preferably, it is connected to the accommodating member 40 by a convenient disassembly and assembly method such as snap connection or interference fit, so as to enclose the clamping shaft 10 in the accommodating groove. Further, when a lifting handle 11 is provided on the clamping shaft 10, when the clamping surface is in the first position, the end cap can be closed onto the accommodating member 40, and the end cap encloses the lifting wrench into the accommodating groove and limits the lifting handle 11. The setting of the end cap enables the clamping shaft 10 and the lifting handle 11, etc. to be enclosed in the accommodating groove, without affecting the normal operation of the agitator 20.

[0050] When it is necessary to disassemble the agitator 20, remove the end cap, pull up the lifting handle 11 to rotate the clamping shaft 10, so that the clamping surface rotates out of the clamping groove 31, and continue to pull up the lifting handle 11 to separate the agitator 20 from the drive shaft 30 and lift the agitator 20. When installing the agitator 20, place the agitator 20 in place, then press the lifting handle 11 to rotate the clamping shaft 10, and the clamping surface rotates into the clamping groove 31 to complete the clamping, and then cover the end cap onto the accommodating member 40 to complete the installation of the agitator 20.

[0051] Preferably, the agitator mounting assembly further includes an insert 50 provided on the agitator 20. The insert 50 includes a fixing plate and a connection hole. The fixing plate is used for fixedly connecting with the agitator 20, and the connection hole is used for sleeving onto the drive shaft 30 and transmitting torque. Preferably, splines are provided on the drive shaft 30, and the connection hole of the insert 50 is configured as a hole adapted to the spline structure and can cooperate with the drive shaft 30 to transmit torque. The setting of the insert 50 can improve the strength of the agitator 20. When the insert 50 is provided, two clamping grooves 31 on the drive shaft 30 can be provided corresponding to one clamping shaft 10 respectively, or the clamping groove 31 can be formed as an annular groove along the circumferential direction of the drive shaft 30, which is more convenient for its assembly with the clamping shaft 10.

[0052] Preferably, the insert 50 and the accommodating member 40 are respectively placed on the upper side and the lower side of the agitator 20, and the insert 50, the accommodating member 40 and the agitator 20 are connected into an integral body through a connecting member. This structure can reduce the torque borne by the agitator 20, and the torque is mainly borne by the insert 50 and the accommodating member 40, thereby improving the reliability of the agitator 20 and the strength of the overall structure.

[0053] The present invention also provides a pulsator washing machine, including the above-mentioned pulsator mounting assembly. The pulsator washing machine includes a drive shaft 30, and a clamping groove 31 is provided on the drive shaft 30. The clamping groove 31 is arranged perpendicular to the axis of the drive shaft 30 and is used for clamping with the clamping shaft 10. Positioning posts or positioning holes for assembling with the pulsator mounting assembly are provided on the pulsator 20 of the pulsator washing machine. Correspondingly, positioning holes or positioning posts are provided on the accommodating and inserting member 50, so that the assembly of the pulsator mounting assembly and the pulsator 20 is more convenient and has higher precision.

[0054] The present invention can achieve the convenient and quick disassembly and assembly of the agitator, making it more convenient for users to clean and maintain the agitator, avoiding the situation where bacteria breed due to inconvenient cleaning of the inner side of the agitator or the parts blocked by it, and improving the health of the washing machine.
