[0002] The related pulsator washing machines and agitator washing machines are both popular among users, and each type of washing machine has its own advantages. The impeller at the bottom of the washing tub of a pulsator washing machine rotates forward and backward, driving the clothes to flip up and down and left and right continuously, so that the clothes, the clothes and the tub wall, and the clothes and the impeller rub against each other, thereby removing dirt and cleaning. The agitator washing machine is equipped with a stirring rod in the center of the impeller at the bottom of the washing tub. The impeller rotates forward and backward and drives the stirring rod installed in the center of the washing tub to rotate, thereby driving the water flow in the machine body and the movement of clothes; the moving water flow pushes the clothes to flip continuously, so that the clothes, the clothes and the tub wall and the stirring rod rub against each other in the water, and the dirt removal and cleaning is achieved under the action of detergent.

[0003] The stirring rod and the pulsator of the related agitator-type washing machine are detachably connected, so that the user can switch between the agitator-type washing machine and the pulsator-type washing machine at any time according to the washing needs of the user.

[0011] In some embodiments, one axial end of the tenon is an end of the tenon away from the body; the cross-sectional area of ​​the tenon decreases from the one end to the other axial end; one axial end of the groove is an open end of the groove close to the body, and the other axial end of the groove is an abutment end of the groove away from the body; the area of ​​the cross section of the groove perpendicular to the axial direction increases from the open end to the abutment end.

[0012] In some embodiments, the first telescopic rod includes: a handle, which is axially protruding from the second end of the body; a rod body, which is located in the cavity, is coaxially arranged with the handle and moves in the cavity and the through hole, and the end of the rod body away from the handle forms a positioning structure for the stirring rod; wherein the handle is provided with a snap-fit ​​structure so as to be detachably connected to the body.

[0013] In some embodiments, the impeller includes: a base plate, on which a plurality of rotary blades are axially arranged; a connecting protrusion, which is used to be detachably connected to the stirring rod, and the plurality of rotary blades are arranged around the connecting protrusion; wherein, the top end of the connecting protrusion is provided with the groove that passes through the connecting protrusion along the first direction, and the wall surface of the groove can abut against the wall surface of the tenon; and the connecting protrusion is provided with the positioning structure that is located at the bottom of the groove and extends along the axial direction.

[0014] In some embodiments, the impeller further includes: a mortise and tenon pin, which can fill the groove and be detachably connected to the connecting protrusion.

[0015] In some embodiments, the mortise and tenon pin includes: a pin body, an axial channel is provided inside, and the pin body can abut against the wall of the groove; a second telescopic rod, which can pass through the channel and move along the channel to protrude the pin body and connect with the positioning structure at the bottom of the groove, and retract into the channel and disconnect from the positioning structure.

[0016] An embodiment of the present invention further provides a clothing processing device, comprising: a barrel body having a accommodating cavity for accommodating clothing; a pulsator assembly as described in any one of the above items, located in the accommodating cavity and the pulsator connected to the bottom of the barrel body.

In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0034] The embodiment of the present invention provides a pulsator assembly and a clothes processing device. The pulsator assembly described in the embodiment of the present invention can be applied to a stirring type washing machine and a pulsator type washing machine. When the pulsator and the stirring rod are installed, it is a stirring type washing machine; when the pulsator and the stirring rod are removed, it is a pulsator type washing machine. It can be understood that the washing machine includes a single washing washing machine with a separate washing function, a washing machine with a washing and dehydrating function, and a washing and drying machine with a washing and drying function.

[0035] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a pulsator assembly 10, which includes a pulsator 1 and a stirring rod 2. The pulsator 1 can rotate around an axial direction, and the axial direction is as shown in FIG. Figure 2 The stirring rod 2 is located above the impeller 1 and is detachably connected to the impeller 1 coaxially, that is, the stirring rod 2 is coaxially arranged with the impeller 1, and the stirring rod 2 is detachably connected to the impeller 1. When the impeller 1 and the stirring rod 2 are connected, the impeller 1 can rotate around the axis, and can drive the stirring rod 2 to rotate around the axis together. Several stirring wings are also arranged on the side wall of the stirring rod 2, which can rotate back and forth within 360° according to the texture, degree of dirtiness, quality of the laundry, etc., and the laundry can be rubbed back and forth in the arms to completely remove the stains.

[0036] like Figure 1 and Figure 2 As shown, the impeller 1 and the stirring rod 2 are both provided with a connecting structure 3 and a positioning structure 4 to realize a detachable connection between the impeller 1 and the stirring rod 2; the connecting structure 3 allows the impeller 1 and the stirring rod 2 to move along a first direction to connect and disconnect, and the first direction is as shown in FIG. Figure 2 The connecting structure 3 provided on the impeller 1 and the connecting structure 3 provided on the stirring rod 2 cooperate with each other and are detachably connected, thereby realizing the detachable connection between the impeller 1 and the stirring rod 2. Figure 1 and Figure 2 As shown, the positioning structure 4 defines the position of the impeller 1 and the stirring rod 2 when the connecting structure 3 between the impeller 1 and the stirring rod 2 is in the connected state. It can be understood that when the connecting structure 3 between the impeller 1 and the stirring rod 2 is in the connected state, the impeller 1 and the stirring rod 2 can still move along the first direction to disconnect, and the positioning structure 4 can define the position of the impeller 1 and the stirring rod 2 when the connecting structure 3 is connected. Therefore, when the positioning structure 4 is defined in place, the impeller 1 and the stirring rod 2 can no longer move along the first direction to disconnect, so that the connection between the impeller 1 and the stirring rod 2 can be more stable and not easy to produce relative movement along the first direction.

[0037] like Figure 1 and Figure 2 As shown, the first direction corresponds to the radial direction of the impeller 1 and the stirring rod 2, which means that the connecting structure 3 provided on the impeller 1 penetrates the radial direction of the impeller 1, and the connecting structure 3 on the stirring rod 2 penetrates the radial direction of the stirring rod 2. The angle between the first direction and the radial direction is a first preset acute angle. Figure 2 The L2 direction shown, the first preset acute angle is as follows Figure 2 When removing the stirring rod 2, the user can apply an oblique upward force to pull the stirring rod 2 to move, so that the stirring rod 2 is disconnected from the connecting structure 3 of the impeller 1; when installing the stirring rod 2 and the impeller 1, the user can apply an oblique downward force to push the stirring rod 2 to move, so that the connecting structure 3 of the stirring rod 2 is connected to the connecting structure 3 of the impeller 1.

[0038] The stirring rod and the impeller are detachably coaxially connected, so that the user can remove or install the stirring rod on the impeller according to actual washing needs; for example, when removing the stirring rod and the impeller, the positioning structure is first removed, and then the connecting structure is removed, so that the stirring rod and the impeller can move along a first direction to disconnect; because the angle between the first direction and the radial direction of the impeller and the stirring rod is a first preset acute angle, the stirring rod can move obliquely upward or obliquely downward relative to the impeller, and a washing tub is provided on the surrounding side of the stirring rod. When removing the stirring rod, the user can apply an oblique upward force to pull the stirring rod to move, so that the stirring rod is disconnected from the impeller. At this time, since the stirring rod moves obliquely upward, the stirring rod has a larger movement space and is not easily restricted by the wall of the washing tub, which facilitates the removal of the stirring rod from the impeller, and when the user pulls it with his hand, pulling the stirring rod obliquely upward facilitates the exertion of human muscles, which conforms to the setting of human body mechanics. When installing the stirring rod and the impeller, the user can apply an oblique downward force to push the stirring rod to move, so that the stirring rod is connected to the impeller, and the gravity of the stirring rod also makes it tend to move downward, which is also convenient for installing the stirring rod and the impeller. Through the joint action of the connecting structure and the positioning structure, the connection between the impeller and the stirring rod can be made stable, so that when the impeller drives the stirring rod to rotate together, the structure used to limit the impeller and the stirring rod is not easy to break, so that the stirring rod and the impeller can be stably limited and rotate together.

[0039] In some embodiments, Figure 1 and Figure 2 As shown, the first preset angle θ is between 15 degrees and 45 degrees. For example, the first preset angle θ can be 25 degrees. The first preset angle θ should not be too small, otherwise the user may pull out the stirring rod 2 roughly in the radial direction when disassembling the stirring rod 2 and the impeller 1, so the user is easily restricted by the wall of the washing tub when disassembling the stirring rod, which is inconvenient for the user to operate; the first preset angle θ should not be too large, otherwise when the stirring rod 2 is connected to the connecting structure 3 of the impeller 1, the stirring rod 2 has a tendency to easily move to one side along the first direction, for example, on the low side of the first direction in the lateral direction, so that the connecting structure 3 of the stirring rod 2 and the impeller 1 is not easy to maintain balance in the connected state, and has a strong movement tendency, so a high-strength positioning structure is required for positioning. If the first preset angle θ is too large and the connecting structure 3 is set too steep, the positioning structure 4 overcomes the gravity to achieve the positioning of the impeller 1 and the stirring rod 2. The force required is also large, so that after long-term use, it is easy to cause the positioning structure to break and fail.

[0040] The first preset angle of the embodiment of the present invention is between 15 degrees and 45 degrees, and the size of the first preset angle is relatively appropriate, so that the stirring rod can move obliquely upward along the first direction to break away from the connection with the impeller, which is convenient for user operation; the stirring rod has a certain tendency to move obliquely downward relative to the impeller, but because the size of the first preset angle is appropriate, its tendency to move obliquely downward is smaller, so that the force required to be borne by the positioning structure during positioning is also smaller, and the positioning structure can better maintain the position of the stirring rod and the impeller when they are in the connected state, so that the stirring rod and the impeller are easy to disassemble and assemble, and the connection strength is also more reliable.

[0041] In some embodiments, Figure 1 and Figure 2 As shown in FIG. 1 , the width of the connection structure 3 changes monotonically along the first direction. Monotonically changing means that the width of the connection structure 3 increases or decreases along the first direction, but the change value is not constant. The width of the connection structure 3 increases as the height of the connection structure 3 increases in the axial direction. The direction where the width is located is perpendicular to the first direction. The first direction can be roughly understood as the direction in which the length of the connection structure 3 extends. The direction where the width is located is as shown in FIG. Figure 3 L3 direction shown. It can be understood that the width of the connecting structure 3 is larger at a high position in the axial direction, and the width of the connecting structure 3 is smaller at a low position in the axial direction. When installing the impeller 1 and the stirring rod 2, the connecting structure 3 of the stirring rod 2 can only be inserted into the connecting structure 3 of the impeller 1 from the end with a larger width, that is, it can only be installed by moving the connecting structure 3 from a high position to a low position in the axial direction, that is, it can be installed by moving obliquely downward until it moves to the end with a smaller width, and the connecting structure 3 of the stirring rod 2 can no longer move, so that the stirring rod 2 can be connected to the connecting structure 3 of the impeller 1 in place, and the balance of the oblique downward movement of the stirring rod 2 can be maintained; when disassembling the impeller 1 and the stirring rod 2, the connecting structure 3 of the stirring rod 2 moves from the end with a smaller width to the end with a larger width, so as to be separated from the connecting structure 3 of the impeller 1, that is, it moves from the low position to the high position in the axial direction of the connecting structure 3, that is, it moves obliquely upward for disassembly.

[0042] The connecting structure of the embodiment of the present invention has a smaller width at the lower end in the axial direction, which can limit the tendency of the stirring rod to move obliquely downward relative to the impeller, and to a certain extent ensure the balance of the connecting structure between the stirring rod and the impeller when they are in place; and only one end of the connecting structure of the impeller can be inserted or detached, thereby preventing errors in the user's operation, allowing the user to disassemble and assemble the stirring rod and the impeller according to the operating method that conforms to ergonomics.

[0043] In some embodiments, Figure 1 and Figure 2As shown, the connection structure 3 includes a mortise and tenon structure 31 provided at one axial end of the stirring rod 2 and at one axial end of the impeller 1, so that the mortise and tenon structure 31 provided at one axial end of the stirring rod 2 and the mortise and tenon structure 31 provided at one axial end of the impeller 1 can be connected and disconnected, and the mortise and tenon structure 31 is located in the middle area of ​​the impeller 1, so that the stirring rod 2 is connected to the middle area of ​​the impeller 1 through the mortise and tenon structure 31. When used in a clothes processing device, the stirring rod 2 is located in the middle area of ​​the barrel, so that when washing clothes, the friction force between the clothes in the barrel and the stirring rod 2 is relatively uniform. Figure 3 and Figure 4 As shown, the positioning structure 4 is located in the corresponding mortise and tenon structure 31, that is, the positioning structure 4 is distributed within the range of the mortise and tenon structure 31. Then, when the mortise and tenon structures 31 of the impeller 1 and the stirring rod 2 are connected in place, the positioning structure 4 can be installed in place, so that the impeller 1 and the stirring rod 2 can be positioned within the range of the mortise and tenon structure 31, thereby limiting the positions of the impeller 1 and the stirring rod 2 in the connected state of the mortise and tenon structure 31.

[0044] The mortise and tenon structure connection is a concave-convex combination of two components. The protruding part is called the tenon (or tenon head); the concave part is called the mortise (or mortise, tenon groove, groove), and the tenon and the mortise bite together to play a connecting role. The mortise and tenon structure is a combination of the tenon (tenon head) and the mortise (groove). It is an ingenious combination of more and less, high and low, long and short between components, which can effectively limit the twisting of wooden parts in all directions. The most basic mortise and tenon structure consists of two components, one of which has the tenon inserted into the mortise of the other, so that the two components are connected and fixed. The part of the tenon that extends into the mortise is called the tenon tongue, and the rest is called the tenon shoulder.

[0045] The connection structure of the embodiment of the present invention includes a mortise and tenon structure provided at one axial end of the stirring rod and at one axial end of the impeller, so that the impeller and the stirring rod can move relative to each other along a first direction to achieve connection and disconnection between the impeller and the stirring rod, and the mortise and tenon structure connection makes the overall structure of the impeller and the stirring rod more solid; the positioning structure is located in the corresponding mortise and tenon structure, so as to limit the position of the impeller and the stirring rod in the mortise and tenon structure connection state, so that the stirring rod and the impeller are not easy to produce relative movement in the first direction, the connection between the stirring rod and the impeller can be more stable, and the connection reliability of the impeller and the stirring rod is improved. The positioning structure is located in the corresponding mortise and tenon structure, so that the two are not easy to lose a large torque due to the long distance, the connection strength between the two is more reliable, and can withstand greater rotational resistance.

[0046] In some embodiments, Figure 4 and Figure 5 As shown, the stirring rod 2 includes a body 21, a first telescopic rod 23 and a tenon 25. The tenon 25 can be detachably connected to the body 21 to replace the tenon 25 of a suitable size. Figure 2As shown, the body 21 has a cavity 22 extending in the axial direction; the tenon 25 is used to form a connection of a mortise and tenon structure 31 with the groove 11 provided on the impeller 1, that is, the tenon 25 slides into the groove 11 along the first direction, thereby forming a connection of the mortise and tenon structure 31; the tenon 25 is arranged to protrude axially from the first end 24 of the body 21, and the first end 24 refers to the end of the body 21 close to the impeller 1 along the axial direction, and the end surface S of the tenon 25 away from the body 21 extends along the first direction; combined Figure 3 and Figure 6 As shown, a through hole 26 extending axially and communicating with the cavity 22 is provided inside the tenon 25, and the through hole 26 passes through the tenon 25; the first telescopic rod 23 can move along the cavity 22 and the through hole 26 to switch between a positioning state protruding from the tenon 25 and an unlocking state retracted into the through hole 26 or the cavity 22; a tubular structure 28 can be provided inside the cavity 22, so that the first telescopic rod 23 moves inside the tubular structure 28, thereby guiding the movement of the first telescopic rod 23. In the positioning state, the part of the first telescopic rod 23 protruding from the tenon 25 forms a connection with the positioning structure 4 with the positioning hole 15 opened inside the groove 11 of the impeller 1. It can be understood that, in the positioning state, the first telescopic rod 23 passes through the cavity 22 and the through hole 26 and protrudes from the tenon 25 to be inserted into the positioning hole 15, thereby limiting the position of the mortise and tenon structure 31 of the impeller 1 and the stirring rod 2 in the connected state; in the unlocked state, the first telescopic rod 23 retracts into the through hole 26 or the cavity 22, at which time the impeller 1 and the stirring rod 2 are not restricted by the positioning structure 4, and the mortise and tenon structure 31 of the impeller 1 and the stirring rod 2 can move along the first direction to connect and disconnect.

[0047] The stirring rod of the embodiment of the present invention includes a main body, a first telescopic rod and a tenon, the tenon is used to connect with the groove opened on the impeller to form a mortise and tenon structure connection, and the mortise and tenon structure connection makes the impeller and the stirring rod firmly connected; the first telescopic rod can move along the cavity and the through hole to switch between a positioning state protruding from the tenon and an unlocked state retracted into the through hole or the cavity; in the positioning state, the part of the first telescopic rod protruding from the tenon forms a positioning structure connection with the positioning hole opened inside the groove of the impeller; therefore, the positioning of the impeller and the stirring rod in the mortise and tenon structure connection state can be controlled by extending and retracting the first telescopic rod back and forth along the axial direction, the structure is simple, and the operation is convenient, which is convenient for users to disassemble and assemble.

[0048] In some embodiments, Figure 5 and Figure 6 As shown, one end of the tenon 25 in the axial direction is the end of the tenon 25 away from the body 21, and the other end of the tenon 25 in the axial direction is close to the end where the tenon 25 is connected to the body 21; the cross-sectional area of ​​the tenon 25 decreases from one end to the other end in the axial direction; Figure 3As shown, one end of the groove 11 in the axial direction is the open end 16 of the groove 11 close to the body 21, and the other end of the groove 11 in the axial direction is the abutment end 17 of the groove 11 away from the body 21; the area of ​​the cross section perpendicular to the axial direction of the groove 11 increases from the open end 16 to the abutment end 17 in the axial direction. That is to say, the cross-sectional area of ​​the groove 11 in the axial direction is small, and the cross-sectional area of ​​the abutment end 17 in the axial direction is large, so that when the tenon 25 is connected with the groove 11 opened on the impeller 1 to form a connection of the mortise and tenon structure 31, that is, after the tenon 25 slides obliquely into the groove 11 along the first direction and cooperates with the groove 11, the tenon 25 is not easy to move in the axial direction and disengage. Specifically, when the tenon 25 moves in the direction of the open end 16 of the axial groove 11, since the cross-sectional area of ​​the groove 11 gradually decreases as it approaches the open end 16, the groove 11 causes axial movement restriction on the portion of the tenon 25 with a relatively larger cross-sectional area, so that the tenon 25 cannot move in the axial direction and is confined in the groove 11.

[0049] The cross-sectional area of ​​the tenon in the embodiment of the present invention decreases from one end away from the body to the other end in the axial direction. Correspondingly, the cross-sectional area of ​​the groove opened on the impeller increases from one end close to the stirring rod to the other end away from the stirring rod in the axial direction. Therefore, when the tenon moves axially toward the open end of the groove, the cross-sectional area of ​​the groove gradually decreases as it approaches the open end, and thus the groove restricts the axial movement of the portion of the tenon with a relatively larger cross-sectional area. As a result, the tenon cannot move axially and is confined in the groove, thereby restricting the stirring rod and the impeller in the axial direction.

[0050] In some embodiments, Figures 2 to 4 As shown, the first telescopic rod 23 includes a handle 231 and a rod body 232. The handle 231 is axially protruding from the second end 27 of the body 21, and the second end 27 refers to the end of the body 21 axially away from the impeller 1; the rod body 232 is located in the cavity 22, coaxially arranged with the handle 231 and moves in the cavity 22 and the through hole 26, and the end of the rod body 232 away from the handle 231 forms a positioning structure 4 for the stirring rod 2; the handle 231 is provided with a snap structure 6 to be detachably connected to the body 21. For example, the snap structure 6 can be a structure of a slot and a snap fit. When the handle 231 is connected to the snap-fit ​​structure 6 of the main body 21, the rod body 232 partially protrudes from the tenon 25 and is inserted into the positioning hole 15. At this time, the position of the mortise and tenon structure 31 of the impeller 1 and the stirring rod 2 in the connected state can be limited; when the impeller and the stirring rod need to be disassembled, the snap-fit ​​structure 6 of the handle 231 and the main body 21 is disassembled, the handle 231 is pulled upward, and the rod body 232 is retracted upward into the through hole 26 or the cavity 22. At this time, the impeller 1 and the stirring rod 2 are not restricted by the positioning structure 4, and the mortise and tenon structure 31 of the impeller 1 and the stirring rod 2 can be moved along the first direction to disconnect.

[0051] The first telescopic rod of the embodiment of the present invention includes a handle and a rod body. The handle protrudes axially from the body, and the handle is relatively large and roughly disc-shaped, which is convenient for users to hold and pull back and forth. In addition, the handle and the body are connected by a snap-fit ​​structure, making them easy to assemble and disassemble. Not only is the structure simple and easy to process, but the connection is also relatively tight.

[0052] In some embodiments, Figure 2 and Figure 3 As shown, the impeller 1 includes a bottom plate 12 and a connecting protrusion 14. The bottom plate 12 is provided with a plurality of rotating blades 13 along the circumferential direction, and the plurality of rotating blades 13 are evenly arranged along the circumferential direction. When the impeller 1 rotates, the plurality of rotating blades 13 increase the friction between the clothes and the impeller 1, so that the clothes and the impeller 1 are rubbed to remove dirt and wash. The connecting protrusion 14 is located at the center of the impeller 1, and the connecting protrusion 14 is used to be detachably connected with the stirring rod 2, and the plurality of rotating blades 13 are arranged around the connecting protrusion 14; wherein, the top of the connecting protrusion 14 is provided with a groove 11 that penetrates the connecting protrusion 14 along the first direction, and the wall surface of the groove 11 can abut against the wall surface of the tenon 25, so that after the tenon 25 slides obliquely into the groove 11 along the first direction and cooperates with the groove 11, the stirring rod 2 and the impeller 1 are connected with the mortise and tenon structure 31, and it is also difficult to rotate along the circumferential direction, so that the stirring rod 2 and the impeller 1 can only move along the first direction. The connecting protrusion 14 is provided with an axially extending positioning structure 4 located at the bottom of the groove 11, namely a positioning hole 15. The portion of the first telescopic rod 23 protruding from the tenon 25 can be axially inserted into the positioning hole 15, thereby positioning the connection state of the mortise and tenon structure 31.

[0053] The impeller of the embodiment of the present invention includes a bottom plate and a connecting protrusion, and a plurality of rotating blades increase the friction between the clothes and the impeller, so that the clothes and the impeller are rubbed to remove dirt and clean; the connecting protrusion is provided with a groove running through the first direction, and the wall surface of the groove can abut against the wall surface of the tenon, thereby limiting the circumferential rotation of the tenon relative to the impeller; and the axial movement of the tenon is also limited by itself, and a positioning hole extending axially at the bottom of the groove is provided on the connecting protrusion. When the first telescopic rod is inserted into the positioning hole, the movement of the tenon relative to the groove along the first direction can be limited, so that the stirring rod and the impeller are restricted in the circumferential, axial and radial directions, and the clothes and the stirring rod are rubbed in the water, resulting in a large rotational resistance to the stirring rod being borne by the mortise and tenon structure, and the mortise and tenon structure has sufficient structural strength, so that the connection between the impeller and the stirring rod is more stable, and in fact the resistance to the stirring rod along the first direction is small, so the positioning structure is sufficient to support the connection between the stirring rod and the impeller.

[0054] In some embodiments, Figure 7 and Figure 8As shown, the impeller 1 also includes a mortise and tenon pin 5, which can fill the groove 11 and be detachably connected to the connecting protrusion 14. The mortise and tenon pin 5 includes a structure similar to a tenon, and the mortise and tenon pin 5 allows relative movement along a first direction between itself and the impeller 1 to connect and disconnect, and the mortise and tenon pin 5 also limits the position of itself and the impeller 1 in a connected state. The length of the mortise and tenon pin 5 is much smaller than the length of the stirring rod 2, and basically only has the function of filling the groove 11, but not the stirring function. The impeller of the embodiment of the present invention also includes a mortise and tenon pin, which can fill the groove and be detachably connected to the connecting protrusion, so that the gap generated on the impeller after the stirring rod is removed can be removably inserted by the mortise and tenon pin to prevent clothes from being entangled in the gap.

[0055] In some embodiments, Fig. 9 and Fig.10 As shown, the mortise and tenon pin 5 includes a pin body 51 and a second telescopic rod 52. The appearance of the pin body 51 is similar to the structure of the tenon, that is, from the third end 54 away from the impeller 1 to the fourth end 55 axially close to the impeller 1, the pin body 51 has a section with an increased cross-sectional area. When placed normally, the pin body 51 has a section with an increased cross-sectional area from top to bottom, so that when the mortise and tenon pin 5 moves axially toward the open end 16 of the groove 11, that is, when it is pulled upward axially, since the cross-sectional area of ​​the groove 11 gradually decreases from bottom to top, the size of the pin body 51 is just matched with the size of the groove 11, and the part with a larger cross-sectional area below the pin body 51 is difficult to move upward to the part with a smaller cross-sectional area above the groove 11, and the pin body 51 can only slide out of the groove 11 along the first direction, so that the mortise and tenon pin 5 cannot move axially and is confined in the groove 11. Among them, an axial channel 53 is opened inside the pin body 51, and the pin body 51 can abut against the wall of the groove 11, thereby limiting the circumferential rotation of the pin body 51 relative to the impeller 1, so that the pin body 51 can stably move along the first direction relative to the impeller 1.

[0056] like Fig. 9 and Fig.10 As shown, the second telescopic rod 52 can pass through the channel 53 and move along the channel 53 to protrude the pin body 51 and connect with the positioning structure 4 at the bottom of the groove 11, and retract into the channel 53 and disconnect from the positioning structure 4. The second telescopic rod 52 and the pin body 51 can also be detachably connected through the buckle structure 6. When the second telescopic rod 52 is connected to the pin body 51, the part of the second telescopic rod 52 protruding from the pin body 51 can be inserted into the positioning hole 15, and the position of the impeller 1 and the mortise and tenon pin 5 in the connected state can be limited; when the impeller 1 and the mortise and tenon pin 5 need to be disassembled, the second telescopic rod 52 and the pin body 51 are disassembled, the second telescopic rod 52 is pulled upward, and the second telescopic rod 52 is retracted upward into the channel 53, and the impeller 1 and the mortise and tenon pin 5 are not restricted by the positioning structure 4, and then the impeller 1 and the mortise and tenon pin 5 are moved along the first direction to disconnect.

[0057] like Figure 1 and Figure 2 As shown, an embodiment of the present invention further provides a clothing processing device, for example, the clothing processing device can be a stirring washing machine, etc. The clothing processing device includes a barrel body and a pulsator assembly 10. Among them, the barrel body has a accommodating cavity for accommodating clothing; the pulsator assembly 10 is located in the accommodating cavity and the pulsator 1 is connected to the bottom of the barrel body. When the clothing processing device is dehydrating, the pulsator 1 and the barrel body both rotate; when washing, the pulsator 1 rotates, the barrel body does not rotate, and the pulsator 1 drives the stirring rod 2 to rotate together, thereby driving the water flow in the body and the movement of clothes; the moving water flow pushes the clothes to turn over continuously, so that the clothes, the clothes and the barrel wall and the stirring rod rub in the water, and the decontamination and cleaning are achieved under the action of the detergent.

[0058] The clothes processing device of the embodiment of the present invention comprises a barrel and a pulsator assembly, wherein the pulsator is connected to the bottom of the barrel. When washing clothes, the pulsator rotates forward and reversely and drives the stirring rod to rotate together, thereby driving the water flow in the machine body and the clothes to move; the moving water flow pushes the clothes to turn over continuously, so that the clothes, the inner wall surface of the barrel and the stirring rod are rubbed in the water, and the decontamination and cleaning are achieved under the action of the detergent. When the pulsator rotates forward and reversely and drives the stirring rod to rotate together, the stirring rod is subjected to a large rotation resistance due to the friction between the clothes and the stirring rod in the water, so that the structure for limiting the pulsator and the stirring rod needs to bear a large rotation resistance. The connection between the pulsator and the stirring rod of the embodiment of the present invention is stable, so that when the pulsator drives the stirring rod to rotate together, the structure for limiting the pulsator and the stirring rod is not easy to break, so that the stirring rod and the pulsator can be stably limited and rotate together. The pulsator and the stirring rod of the embodiment of the present invention are easy to disassemble and assemble. When disassembling and assembling, the stirring rod can be pulled out obliquely upward or inserted obliquely downward from the pulsator at the bottom of the barrel, which is not easily restricted by the surrounding barrel wall surface and meets the requirements of human mechanics.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
