[0001] The utility model belongs to the technical field of washing devices, in particular to the technical field of a stirring mechanism, in particular to a detachable stirring mechanism. Background Art

[0002] After long-term use, the stirring mechanism in the washing device will accumulate dirt at the bottom of the stirring mechanism. If it is not cleaned in time, the dirt hidden at the bottom of the stirring mechanism will contaminate the laundry during subsequent washing, causing cross infection. For example, a pulsator washing machine is provided with a rotatable inner barrel with agitating ribs. The entire inner barrel rotates to stir the washing water and turn the laundry. However, since the inner barrel and the outer barrel cannot be directly scrubbed, more dirt will adhere to the outer wall of the inner barrel after long-term use, and enter the inner barrel through the water hole during the subsequent washing process; or, the pulsator is independently provided with the inner barrel. During washing, only the pulsator rotates to stir the laundry and the washing water. There is also a dead corner between the pulsator and the inner barrel that is difficult to scrub.

[0003] When the dirt accumulated on the stirring mechanism needs to be cleaned, the stirring mechanism needs to be disassembled for separate cleaning, and the existing stirring mechanism is usually fixedly connected to the bottom of the washing machine by screws, and the screws need to be removed before the stirring mechanism is removed for separate cleaning.

The terms "set", "open", "install", "connected" and "connected" should be understood in a broad sense. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. And in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0032] The utility model provides a detachable stirring mechanism, comprising a stirring body 1, a driving shaft 3, and a locking assembly. The driving shaft 3 is connected to a driving device in a washing device 2, and the locking assembly is arranged at the center of the stirring body 1. The locking assembly comprises a fixing sleeve 4 and a clamping member 5. The fixing sleeve 4 is hollow to form a mounting cavity 41. The driving shaft 3 is detachably connected to the stirring body 1, one end of the driving shaft 3 extends into the mounting cavity 41, and a clamping groove 31 is arranged on the driving shaft 3. The clamping member 5 can move radially along the mounting cavity 41 under external force to realize the clamping and separation of the clamping member 5 and the clamping groove 31.

[0033] The stirring mechanism can be a separately rotating impeller, or a rotatable inner drum provided with water stirring ribs, or other rotating mechanisms that can stir the washing water and turn over the washings. When the stirring mechanism is a impeller provided independently of the washing drum, the impeller is separated from the washing drum and the impeller is separated from the driving device through a locking assembly; when the stirring mechanism is a rotatable inner drum provided with water stirring ribs, the inner drum is separated from the driving device through a locking assembly.

[0034] One end of the drive shaft 3 extends into the mounting cavity 41 of the locking assembly, and the other end of the drive shaft 3 is fixedly connected to the drive device in the washing device 2. The agitating body 1 is detachably connected to the drive shaft 3 through the locking assembly, thereby realizing the detachable connection between the agitating mechanism and the washing device 2; when the agitating mechanism remains connected to the washing device 2, the clamping member 5 moves radially toward the mounting cavity 41 under external force, and extends into the mounting cavity 41 to be clamped into the clamping groove 31, thereby realizing the locking of the agitating body 1 and the drive shaft 3; when the agitating mechanism needs to be separated from the washing device 2, the clamping member 5 is moved away from the mounting cavity 41 by external force, so that the clamping member 5 is separated from the clamping groove 31, and then the agitating mechanism can be removed from the washing device 2.

[0035] Specifically, the clamping member 5 is a ball, the clamping groove 31 is an annular groove, a through hole is provided on the fixing sleeve 4, the diameter of the through hole is smaller than the diameter of the ball, the ball extends into the mounting cavity 41 through the through hole, and is clamped into the clamping groove 31, thereby realizing the locking of the drive shaft 3 by the locking assembly; further, in order to ensure that the stirring body 1 can be stably connected to the drive shaft 3, three through holes are evenly provided on the fixing sleeve 4, and the number of balls is set to be the same as the number of through holes, so that the balls can lock the drive shaft 3 from three directions.

[0036] The locking assembly also includes a sliding sleeve 6, which is arranged outside the fixed sleeve 4, and the clamping piece 5 is arranged between the sliding sleeve 6 and the fixed sleeve 4. The sliding sleeve 6 can move axially along the fixed sleeve 4 under external force; specifically, the sliding sleeve 6 is arranged outside the fixed sleeve 4, and the sliding sleeve 6 can move up and down relative to the fixed sleeve 4. The sliding sleeve 6 restricts the clamping piece 5 in the sliding sleeve 6, thereby limiting the radial movement of the clamping piece 5.

[0037] Further, such as Figure 8 As shown, the lower end of the sliding sleeve 6 is a tapered section 62. When the sliding sleeve 6 is pulled upward, that is, when the sliding sleeve 6 moves away from the driving device, the tapered section 62 releases the squeezing of the clamping member 5, and the clamping member 5 can move between the sliding sleeve 6 and the fixed sleeve 4; when the sliding sleeve 6 is reset downward, that is, when the sliding sleeve 6 moves toward the driving device, the tapered section 62 squeezes the clamping member 5, and the clamping member 5 partially extends into the installation cavity 41 under the squeezing of the tapered section 62.

[0038] In order to limit the maximum upward displacement of the sliding sleeve 6, a top cover 7 is arranged on the top of the sliding sleeve 6, and the bottom of the top cover 7 is connected to the top of the fixed sleeve 4 through a snap fastener 71. The top cover 7 is installed in the form of the snap fastener 71 for easier installation during assembly; the edge of the top cover 7 extends outward to form a rib 72, and an abutment portion 61 matching the rib 72 is arranged inside the sliding sleeve 6. After the sliding sleeve 6 is pulled upward, the abutment portion 61 abuts against the rib 72 to limit the sliding sleeve 6, thereby limiting the maximum displacement of the sliding sleeve 6 toward the top cover 7.

[0039] In order to realize automatic reset of the sleeve 6 after being pulled up, a reset member 8 is arranged between the top cover 7 and the sleeve 6. Specifically, the reset member 8 is a reset spring. The reset spring is arranged in a cavity surrounded by the top cover 7, the fixed sleeve 4 and the sleeve 6. The reset spring sleeve is arranged outside the fixed sleeve 4. When the sleeve 6 is pulled up, the abutment part inside the sleeve 6 compresses the reset spring. After the external force on the sleeve 6 stops, the sleeve 6 moves downward under the elastic force of the reset spring, thereby realizing automatic reset of the sleeve 6.

[0040] The stirring mechanism also includes a stirring sleeve 9 arranged at the bottom of the stirring body 1. The stirring body 1 and the fixed sleeve 4 are fixedly connected to the stirring sleeve 9, and the synchronous movement of the stirring body 1 and the fixed sleeve 4 is realized through the stirring sleeve 9; a docking hole 91 connected to the installation cavity 41 is opened on the stirring sleeve 9. When the stirring mechanism is installed on the washing device 2, the driving shaft 3 passes through the docking hole 91 and extends into the installation cavity 41, and is locked on the stirring mechanism by the locking assembly. When the driving shaft 3 rotates, it drives the stirring sleeve 9, the fixed sleeve 4, and the stirring body 1 to rotate synchronously.

[0041] The docking hole 91 is set to a rectangular, elliptical or quasi-rectangular shape, and any shape that can transmit torque can be adopted. The docking hole 91 is preferably a waist-shaped hole. Correspondingly, a shaft neck section 32 is set on the driving shaft 3, and at least one plane is provided on the shaft neck section 22. Through the cooperation between the shaft neck section 32 and the docking hole 91, the driving device drives the stirring mechanism to rotate; or, matching spline sleeves and spline shafts are respectively provided on the stirring shaft sleeve 9 and the driving shaft 3, and the stirring mechanism is connected to the driving device by means of splines.

[0042] A filter device 10 is also provided at the bottom of the stirring body 1 for collecting impurities such as fluff and thread scraps. The filter device 10 includes a first filter screen 101 and a second filter screen 102. The aperture of the first filter screen 101 is larger than that of the second filter screen 102. Impurities such as fluff and thread scraps enter the filter device 10 from the first filter screen 101 along with the washing water and are intercepted in the filter device 10. Specifically, the first filter screen 101 is provided on the side wall of the stirring body 1, and the second filter screen 102 is provided at the bottom of the stirring body 1. Washing water containing impurities flows into the filter device 10 from the side wall of the stirring body 1. Impurities such as fluff and thread scraps are intercepted before the second filter screen 102. Washing water flows out from the second filter screen 102, thereby reducing the amount of impurities that flow back into the washing area. In order to facilitate the cleaning of impurities in the filter device 10, an openable and closable cover is provided on the filter device 10. After the stirring mechanism is removed from the washing device 2, the cover can be opened and the impurities in the filter device 10 can be poured out.

[0043] According to the utility model, when installing the stirring mechanism, the sliding sleeve 6 is pulled upward to make the clamping member 5 lose the limiting pressure, and the stirring mechanism is installed on the driving shaft 3. At this time, the driving shaft 3 squeezes the clamping member 5, and the clamping member 5 moves away from the installation cavity 41. When the installation is in place, the sliding sleeve 6 is released, and the sliding sleeve 6 is automatically reset under the action of the reset member 8. The clamping member 5 partially extends into the installation cavity 41 under the squeezing of the sliding sleeve 6 and is clamped on the clamping groove 31, thereby realizing the locking of the stirring mechanism and the driving device; when disassembling the stirring mechanism, the sliding sleeve 6 is pulled upward to make the clamping member 5 lose the limiting pressure. When the stirring mechanism is taken out, the driving shaft 3 squeezes the clamping member 5, and the clamping member 5 moves away from the installation cavity 41, thereby disassembling the stirring mechanism. In addition, after disassembling the stirring mechanism, the filter device 10 at the bottom of the stirring mechanism can be opened for separate cleaning.
