[0029] An embodiment of the present invention provides a clothing processing device. The clothing processing device includes a pulsator assembly. The pulsator assembly described in the embodiment of the present invention can be applied to a stirring washing machine. The pulsator and the stirring rod are both provided with a first connection structure and a second connection structure for detachable connection; the first connection structure limits the relative movement of the stirring rod and the pulsator along the rotation axis, and the second connection structure limits the relative rotation of the stirring rod and the pulsator around the rotation axis, so that the connection between the pulsator and the stirring rod can be more stable, thereby improving the connection reliability of the pulsator and the stirring rod. It can be understood that the washing machine includes a single-wash washing machine with a separate washing function, a washing machine with a washing and dehydrating function, and a washing-drying machine with a washing and drying function.

[0030] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a clothing processing device, which includes a pulsator assembly 10, and the pulsator assembly 10 includes a pulsator 1 and a stirring rod 2. The pulsator 1 can rotate around a rotation axis; the stirring rod 2 is detachably connected to the pulsator 1 coaxially, that is, the stirring rod 2 is coaxially arranged with the pulsator 1, and the stirring rod 2 is detachably connected to the pulsator 1. When the pulsator 1 and the stirring rod 2 are connected, the pulsator 1 can rotate around the rotation axis, and can drive the stirring rod 2 to rotate around the rotation axis together; the pulsator 1 and the stirring rod 2 are both provided with a first connection structure 3 and a second connection structure 4 for detachable connection, that is, the pulsator 1 and the stirring rod 2 are detachably connected through the first connection structure 3 and the second connection structure 4, for example, the first connection structure 3 is used for upper and lower limit of the pulsator 1 and the stirring rod 2, and the second connection structure 4 is used for rotation limit of the pulsator 1 and the stirring rod 2. The first connection structure 3 and the second connection structure 4 can double limit the connection between the pulsator 1 and the stirring rod 2. The side wall of the stirring rod 2 is also provided with several stirring wings, which can rotate back and forth within 360°, fast or slow, according to the texture of the clothes, the degree of dirtiness, the quality of the laundry, etc. The clothes can be rubbed back and forth in the arms to completely remove the stains.

[0031] like Figure 1 and Figure 2As shown, the first connecting structure 3 limits the relative sliding of the stirring rod 2 and the impeller 1 along the rotation axis, and the second connecting structure 4 limits the relative rotation of the stirring rod 2 and the impeller 1 around the rotation axis. Therefore, under the limitation of the first connecting structure 3, the stirring rod 2 and the impeller 1 are not easy to slide relative to each other along the rotation axis, but the stirring rod 2 and the impeller 1 are easy to rotate relative to each other around the rotation axis. Under the action of the second connecting structure 4, the relative rotation of the stirring rod 2 and the impeller 1 around the rotation axis can be limited, so that the stirring rod 2 and the impeller 1 are not easy to rotate relative to each other around the rotation axis. Through the dual limitation of the first connecting structure 3 and the second connecting structure 4, that is, the relative sliding and relative rotation of the stirring rod 2 and the impeller 1 along the rotation axis and around the rotation axis are limited respectively, the stirring rod 2 and the impeller 1 are not easy to produce relative movement, and the connection between the stirring rod 2 and the impeller 1 can be more stable.

[0032] like Figure 3 and Figure 4 As shown, the stirring rod 2 includes a body 21 and a clutch rod 23. The body 21 has a cavity 22; the clutch rod 23 is located in the cavity 22, the clutch rod 23 is coaxially arranged with the body 21, and the clutch rod 23 can generate relative motion with the body 21 along the extension direction of the rotation axis; the body 21 is provided with a first connection structure 3 to connect with the impeller 1; the clutch rod 23 is provided with a second connection structure 4 to connect with the impeller 1, and the clutch rod 23 is also provided with a third connection structure 5 to connect with the body 21, and the third connection structure 5 limits the relative rotation of the clutch rod 23 and the body 21 around the rotation axis.

[0033] The stirring rod and the impeller in the embodiment of the present invention are detachably connected, so that the user can remove or install the stirring rod on the impeller according to actual washing needs; the first connecting structure and the second connecting structure for detachable connection are provided on the impeller and the stirring rod, and the two connecting structures can doubly limit the connection between the impeller and the stirring rod; the first connecting structure limits the relative movement of the stirring rod and the impeller along the rotation axis, and the second connecting structure limits the relative rotation of the stirring rod and the impeller around the rotation axis. The relative sliding of the stirring rod and the impeller along the rotation axis and the relative rotation around the rotation axis are respectively limited by the first connecting structure and the second connecting structure, so that the resistance is dispersed, the stirring rod and the impeller are not easy to produce relative movement, 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 stirring rod is connected to the impeller by a second connecting structure provided on the clutch rod, and is also connected to the stirring rod body by a third connecting structure. The two connecting structures respectively realize connection with the stirring rod body and the impeller. Therefore, when the stirring rod body is subjected to a large rotational resistance, the resistance can be transmitted to the clutch rod to share the resistance, and the relative rotation of the stirring rod body and the impeller around the rotation axis is limited by the second connecting structure of the clutch rod. The third connecting structure connects the body and the clutch rod, so that when the stirring rod body is subjected to rotational resistance, the rotational resistance can be dispersed to the body and the clutch rod to share, thereby reducing the risk of breakage caused by the resistance concentrated on one component.

[0034] In some embodiments, Figure 1 and Figure 2 As shown, when the impeller 1 is connected to the stirring rod 2, the first connecting structure 3 is radially located on the outside of the second connecting structure 4. Since the first connecting structure 3 limits the relative sliding of the stirring rod 2 and the impeller 1 along the rotation axis, and the second connecting structure 4 limits the relative rotation of the stirring rod 2 and the impeller 1 around the rotation axis, during the actual washing process, firstly, the first connecting structure 3 is subject to a larger rotational resistance, and secondly, under the limitation of the second connecting structure 4, the impeller 1 and the stirring rod 2 can be connected more firmly through the first connecting structure 3, and are not prone to relative sliding along the rotation axis due to the rotational resistance. The first connecting structure 3 is subjected to a part of the rotational resistance and then transmitted to the second connecting structure 4. The second connecting structure 4 further bears the rotational resistance. Therefore, compared with the case where it is directly subjected to the rotational resistance, the second connecting structure 4 is radially located on the inside of the first connecting structure 3, so that the second connecting structure 4 is not easy to break.

[0035] like Figure 1 and Figure 2As shown, the first connection structure 3 and the second connection structure 4 at least partially overlap in the extension direction of the rotation axis. It can be understood that on a plane parallel to the rotation axis, the projections of the first connection structure 3 and the second connection structure 4 on the plane have overlapping parts, that is, the first connection structure 3 and the second connection structure 4 have overlapping parts in the extension direction of the rotation axis, which can be partial overlap or full overlap. The overlapping part of the first connection structure 3 and the second connection structure 4 on the rotation axis improves the connection stability between the impeller 1 and the stirring rod 2. In the embodiment of the present invention, when the impeller is connected to the stirring rod, the first connection structure and the second connection structure at least partially overlap on the rotation axis, that is, the first connection structure and the second connection structure have overlapping parts on the rotation axis, so that the connection between the impeller and the stirring rod can be more stable, thereby improving the connection reliability between the impeller and the stirring rod.

[0036] In some embodiments, Figure 1 and Figure 2 As shown, the first connection structure 3 is a thread arranged around the rotation axis, and the stirring rod 2 and the impeller 1 are threadedly connected through the first connection structure 3, so that the relative sliding of the stirring rod 2 and the impeller 1 along the rotation axis can be limited; the second connection structure 4 is a protrusion or groove arranged at intervals around the rotation axis, and the stirring rod 2 and the impeller 1 are connected through the second connection structure 4, that is, the protrusions arranged at intervals are inserted into the corresponding grooves to cooperate to limit the relative rotation of the stirring rod 2 and the impeller 1 around the rotation axis. The first connection structure of the embodiment of the present invention is a thread arranged around the rotation axis, and the second connection structure is a protrusion or groove arranged at intervals around the rotation axis, so that the stirring rod and the impeller are threadedly connected through the first connection structure, and the stirring rod and the impeller are not easy to slide relative to each other along the rotation axis; the stirring rod and the impeller are connected through the second connection structure, that is, the protrusions arranged at intervals are inserted into the corresponding grooves to cooperate, so that the stirring rod and the impeller are not easy to rotate relative to each other around the rotation axis; through the dual restrictions of the first connection structure and the second connection structure, the stirring rod and the impeller are not easy to produce relative movement, and the connection between the stirring rod and the impeller can be more stable.

[0037] In some embodiments, Figure 3 and Figure 4 As shown, in the extension direction of the rotation axis, the end of the clutch rod 23 close to the impeller 1 is provided with a second connection structure 4 connected to the impeller 1, for example, the second connection structure 4 is a protrusion or groove arranged at intervals around the rotation axis, and the second connection structure 4 limits the relative rotation of the stirring rod 2 and the impeller 1 around the rotation axis; in the extension direction of the rotation axis, the end of the body 21 close to the impeller 1 is provided with a first connection structure 3 connected to the impeller 1, for example, the first connection structure 3 is a thread arranged around the rotation axis, and the first connection structure 3 limits the relative sliding of the stirring rod 2 and the impeller 1 along the rotation axis. Therefore, when the stirring rod 2 is installed on the impeller 1, the clutch rod 23 can slide relative to the body 21 along the rotation axis.

[0038] Combination Figure 1 and Figure 2 As shown, the second connection structure 4 of the clutch rod 23 and the first connection structure 3 of the body 21 both surround the rotation axis. When the stirring rod 2 is installed on the impeller 1, in order to avoid the interference of the second connection structure 4 on the first connection structure 3 and the impeller 1, the clutch rod 23 is first pulled in the direction away from the impeller 1 to drive the second connection structure 4 to move in the direction away from the impeller 1, and then the stirring rod 2 and the impeller 1 are connected through the first connection structure 3, for example, a threaded connection. When the first connection structure 3 is connected in place, the clutch rod 23 is released, and the second connection structure 4 set at one end of the rotation axis of the clutch rod 23 extends into the impeller 1, and the stirring rod 2 is installed in place. When removing the stirring rod 2 from the impeller 1, in order to avoid the interference of the second connecting structure 4 with the first connecting structure 3 and the impeller 1, first pull the clutch rod 23 in the direction away from the impeller 1 to drive the second connecting structure 4 to move in the direction away from the impeller 1, so that the second connecting structure 4 arranged at one end of the rotation axis of the clutch rod 23 is disengaged from the impeller 1, and then the first connecting structure 3 of the stirring rod 2 is removed from the impeller 1. For example, rotate the stirring rod 2 to remove the first connecting structure 3 from the impeller 1. When the first connecting structure 3 is removed into place, release the clutch rod 23 and remove it into place at the same time.

[0039] The clutch rod of the embodiment of the present invention is provided with a second connection structure connected to the impeller at one end of the rotation axis, and the body is provided with a first connection structure connected to the impeller at one end of the rotation axis, so that the stirring rod is connected to the impeller, and can be connected to the impeller through the second connection structure of the clutch rod to limit the relative rotation of the stirring rod and the impeller around the rotation axis, and the first connection structure of the body is connected to the impeller to limit the relative sliding of the stirring rod and the impeller along the rotation axis. The clutch rod is coaxially arranged with the body and can slide relatively along the rotation axis, so that when the stirring rod is removed from the impeller or installed on the impeller, the clutch rod can be pulled in a direction away from the impeller to drive the second connection structure to move in a direction away from the impeller, thereby avoiding the interference of the second connection structure with the first connection structure and the impeller.

[0040] In some embodiments, Figure 1 and Figure 4As shown, the clutch lever 23 includes a handle 24 and a rod body 25. A retractable elastic member 26 is disposed between the handle 24 and the body 21, for example, the elastic member 26 may be a spring, etc. The rod body 25 is coaxially disposed with the handle 24 and connected to a side of the handle 24 away from the elastic member 26, and a second connection structure 4 is disposed around the rod body 25 at one end of the rod body 25 away from the handle 24. Among them, when the stirring rod 2 is connected to the impeller 1, the elastic member 26 is initially in a compressed state, and the elastic member 26 presses the clutch rod 23 so that the stirring rod 2 and the impeller 1 are stably connected through the second connecting structure 4; when the stirring rod 2 is removed from the impeller 1 or the stirring rod 2 is installed on the impeller 1, the clutch rod 23 can be pulled in the direction away from the impeller 1 to drive the second connecting structure 4 to move in the direction away from the impeller 1, and the elastic member 26 is further compressed. When the first connecting structure 3 is installed or removed in place, the clutch rod 23 is released, and the elastic member 26 returns to its original state, so that the elastic member 26 further presses the second connecting structure 4, and the second connecting structure 4 extends into the impeller 1, and the stirring rod 2 is installed in place; or the disassembly is completed at the same time when the clutch rod 23 is released.

[0041] The clutch rod of the embodiment of the present invention comprises a handle and a rod body, and a retractable elastic member is arranged between the handle and the body. When the stirring rod is connected to the impeller, the initial state of the elastic member is a compressed state, and the elastic member presses the clutch rod so that the stirring rod and the impeller are stably connected through the second connecting structure; when the stirring rod is removed from the impeller or installed on the impeller, the clutch rod can be pulled in a direction away from the impeller to drive the second connecting structure to move in a direction away from the impeller, and the elastic member is further compressed at this time. When the first connecting structure is installed or removed in place, the clutch rod is released, and the elastic member is restored to its original state, so that the elastic member further presses the second connecting structure, and the second connecting structure extends into the impeller, and the stirring rod is installed in place; or the disassembly is completed at the same time when the clutch rod is released. The pressing of the elastic member ensures that the stirring rod and the impeller can be stably connected through the second connecting structure, and when the first connecting structure is installed or removed in place, the clutch rod pulled to avoid interference between the first connecting structure and the impeller can be restored to its original state under the pressing of the elastic member, ensuring that the second connecting structure can also be installed or removed in place.

[0042] In some embodiments, Figure 4As shown, the rod body 25 includes a first extension portion 251 and a second extension portion 252. The diameter of the first extension portion 251 is greater than the diameter of the second extension portion 252. The first extension portion 251 represents a portion with a larger diameter and the second extension portion 252 represents a portion with a smaller diameter and the like. Among them, one end of the first extension portion 251 is connected to the handle 24, and the other end is provided with a third connection structure 5 around the rotation axis. The third connection structure 5 and the inner wall of the body 21 can be slidably connected along the rotation axis. After the rod body 25 is connected to the inner wall of the body 21 through the third connection structure 5, when the handle 24 is pulled or released, the rod body 25 can slide relative to the body 21 along the extension direction of the rotation axis. When the handle 24 is pulled or released, the third connection structure 5 is always connected to the inner wall of the body 21 along the rotation axis. And through the third connection structure 5, the body 21 can drive the rod body 25 to rotate relatively around the rotation axis, so that under the restriction of the third connection structure 5, the rod body 25 and the body 21 are not prone to relative rotation around the rotation axis. The second extension portion 252 is disposed at the other end of the first extension portion 251, and the second extension portion 252 is provided with a second connection structure 4 disposed around the rotation axis, for example, in combination with Figure 5 As shown, the second connecting structure 4 is a protrusion or groove arranged at intervals around the rotation axis, and the second extension part 252 is connected to the impeller 1 through the second connecting structure 4, that is, the protrusions arranged at intervals are inserted into the corresponding grooves to cooperate to limit the relative rotation of the second extension part 252 and the impeller 1 around the rotation axis.

[0043] The rod body of the embodiment of the present invention includes a first extension part and a second extension part, one end of the first extension part is connected to the handle, and the other end is provided with a third connection structure around the rotation axis, and the third connection structure can be slidably connected to the inner wall of the body along the rotation axis, so that when the handle is pulled or released, the rod body can slide along the rotation axis relative to the body, and the third connection structure can provide a guide for the sliding of the rotation axis, so that the rod body can slide along the rotation axis more smoothly relative to the body; the second extension part is provided at the other end of the first extension part, and the second extension part is provided with a second connection structure provided around the rotation axis, so that the second extension part is connected to the impeller through the second connection structure to limit the relative rotation of the second extension part and the impeller around the rotation axis, so that the connection between the impeller and the stirring rod can be more stable in cooperation with the first connection structure, and the connection reliability of the impeller and the stirring rod is improved. The third connection structure limits the relative rotation of the rod body and the body around the rotation axis, so that under the dual restrictions of the second connection structure and the third connection structure, the relative rotation of the rod body and the body around the rotation axis can be limited.

[0044] In some embodiments, Figure 2 and Figure 3As shown, the body 21 includes a cover 211 and a hollow cylinder 212. The cover 211 and the hollow cylinder 212 are fixedly connected, the cover 211 closes one end of the cavity 22, and the elastic member 26 is located between the closed end of the cover 211 and the handle 24 to abut against the cover 211 and the handle 24, so that when the handle 24 is pulled toward the closed end of the cover 211, the elastic member 26 is further compressed from the initial state, and when the handle 24 is released, the elastic member 26 returns to the initial state. Figure 1 As shown, the hollow cylinder 212 is connected to the cover body 211 and extends along the rotation axis. The inner wall surface of one end of the hollow cylinder 212 away from the cover body 211 is provided with a first connection structure 3 connected to the impeller 1. For example, the first connection structure 3 is a thread arranged around the rotation axis. The hollow cylinder 212 and the impeller 1 are threadedly connected through the first connection structure 3, thereby limiting the relative sliding of the hollow cylinder 212 and the impeller 1 along the rotation axis. Figure 6 As shown, the inner wall surface of the end of the hollow cylinder 212 away from the cover body 211 is also provided with a third connection structure 5 to connect with the third connection structure 5 of the first extension portion 251. The third connection structure 5 and the first connection structure 3 are spaced apart at the rotation axis, and through the third connection structure 5, the hollow cylinder 212 can be slidably connected to the inner wall of the body 21 along the rotation axis.

[0045] The body of the embodiment of the present invention includes a cover body and a hollow cylinder, and the elastic member abuts the cover body and the handle. The elastic member does not affect the pulling and releasing of the handle when the stirring rod and the impeller are installed or removed. For example, when the handle is pulled in the direction of the closed end of the cover body, the elastic member is further compressed from the initial state, and when the handle is released, the elastic member returns to the initial state. And when the clutch rod is installed on the impeller through the second connection structure, the elastic member presses the handle of the clutch rod, so that the clutch rod can be stably installed on the impeller, and it is not easy to move along the rotation axis, resulting in an unstable connection.

[0046] In some embodiments, Figure 1 and Figure 4As shown, the third connecting structure 5 is a protrusion or groove arranged at intervals around the rotation axis. For example, a groove is arranged on the inner wall surface of one end of the hollow cylinder 212 away from the cover body 211, one end of the first extension part 251 is connected to the handle 24, and the other end is arranged with a protrusion around the rotation axis, so that the groove of the hollow cylinder 212 and the protrusion arranged around the rotation axis at the other end of the first extension part 251 are slidably connected along the rotation axis; or, a protrusion is arranged on the inner wall surface of one end of the hollow cylinder 212 away from the cover body 211, one end of the first extension part 251 is connected to the handle 24, and the other end is arranged with a groove around the rotation axis, so that the protrusion of the hollow cylinder 212 and the groove arranged around the rotation axis at the other end of the first extension part 251 are slidably connected along the rotation axis. The third connecting structure 5 of the embodiment of the present invention is a protrusion or groove arranged at intervals around the rotation axis, so that the protrusion or groove of the hollow cylinder is slidably connected to the groove or protrusion arranged around the rotation axis at the other end of the first extension part along the rotation axis, and the third connecting structure limits the relative rotation of the rod body and the hollow cylinder around the rotation axis, so that under the dual restrictions of the second connecting structure and the third connecting structure, the relative rotation of the rod body and the hollow cylinder around the rotation axis can be limited.

[0047] In some embodiments, Figure 1 and Figure 2 As shown, the impeller 1 includes a connecting portion 11 and a main body 12. The connecting portion 11 is arranged at one end of the impeller 1 close to the stirring rod 2 to connect with the stirring rod 2; the connecting portion 11 extends in the direction of the rotation axis; the main body 12 is arranged around the connecting portion 11, and an annular groove 13 around the rotation axis is provided between the main body 12 and the connecting portion 11 for the stirring rod 2 to be inserted; the side wall 111 of the connecting portion 11 is provided with a first connecting structure 3, and the inner wall surface of the end of the hollow cylinder 212 away from the cover body 211 is provided with the first connecting structure 3 connected with the impeller 1, for example, the first connecting structure 3 is a thread arranged around the rotation axis, and the stirring rod 2 is threadedly connected to the connecting portion 11 through the first connecting structure 3, so that the stirring rod 2 and the impeller 1 can be limited from sliding relative to each other along the rotation axis; and In the radial direction of the main body 12, the side wall 111 is located on the side of the annular groove 13 away from the main body 12; the side wall 111 is the outer side wall of the connecting part 11 close to the annular groove 13; and in the extension direction of the rotation axis, the end wall 112 of the connecting part 11 is provided with a second connecting structure 4, and the end wall 112 is the top wall of the connecting part 11 close to the stirring rod 2, and the second connecting structure 4 is provided around the rod body 25 at one end of the rod body 25 away from the handle 24. For example, the second connecting structure 4 is a protrusion or groove arranged at intervals around the rotation axis, and the rod body 25 is connected to the impeller 1 through the second connecting structure 4, that is, the protrusions arranged at intervals are inserted into the corresponding grooves to cooperate to limit the relative rotation of the rod body 25 and the impeller 1 around the rotation axis.

[0048] The impeller of the embodiment of the present invention includes a connecting portion and a main body portion, the side wall of the connecting portion is provided with a first connecting structure, the hollow cylinder is threadedly connected to the connecting portion through the first connecting structure, so that the relative sliding of the hollow cylinder and the connecting portion along the rotation axis can be limited; the third connecting structure limits the relative rotation of the rod body and the hollow cylinder around the rotation axis, and the second connecting structure limits the relative rotation of the rod body and the connecting portion around the rotation axis, so that under the dual restrictions of the second connecting structure and the third connecting structure, the relative rotation of the rod body and the hollow cylinder around the rotation axis can be limited. When the hollow cylinder is subjected to a large rotation resistance, since both the second connecting structure and the third connecting structure can limit the relative rotation of the rod body and the hollow cylinder around the rotation axis, the large rotation resistance that the two connecting structures need to bear when used for the rotation limit of the rod body and the hollow cylinder can be dispersed, and the second connecting structure and the third connecting structure are not easy to break, so that the stirring rod and the impeller can be stably limited and rotate together.

[0049] like Figure 1 and Figure 2 As shown, the clothing processing device can be a stirring washing machine, etc. The clothing processing device also includes a barrel and a pulsator assembly 10. The barrel has a receiving cavity for receiving clothing; the pulsator assembly 10, that is, the pulsator 1 and the stirring rod 2 are both located in the receiving cavity and the pulsator 1 is connected to the bottom of the barrel. When the clothing processing device is dehydrating, the pulsator 1 and the barrel rotate; when washing, the pulsator 1 rotates, the barrel does not rotate, and the pulsator 1 drives the stirring rod 2 to rotate together, thereby driving the water flow in the machine 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.

[0050] The clothing processing device of the embodiment of the present invention also includes a barrel body, and the impeller is connected to the bottom of the barrel body. When washing clothes, the impeller rotates forward and reversely and drives the stirring rod 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 inner wall surface of the barrel body and the stirring rod are rubbed in the water, and the decontamination and cleaning are achieved under the action of the detergent. When the impeller rotates forward and reversely and drives the stirring rod to rotate together, the stirring rod is subjected to a large rotational resistance due to the friction between the clothes and the stirring rod in the water, so that the structure for limiting the rotation of the impeller and the stirring rod needs to bear a large rotational resistance. The connection between the impeller and the stirring rod in the embodiment of the present invention is stable, so that when the impeller drives the stirring rod to rotate together, the structure for limiting the rotation of 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.

[0051] 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.
