[0040] The embodiment of the present invention provides a stirring device, which can be applied to washing machines, dishwashers, shoe washers, fruit and vegetable cleaning machines, etc. It should be noted that the application scenario type of the embodiment of the present invention does not limit the structure of the stirring device of the embodiment of the present invention.

[0041] like Figure 1 As shown, an embodiment of the present invention provides a stirring device, such as Figure 1-Figure 3 As shown, Figure 1 The embodiment shown is a schematic diagram of the connection between the stirring rod 1 and the pulsator 3. In some embodiments, the stirring rod 1 and the pulsator 3 can be used together to improve the washing efficiency. Figure 1 , Figure 2 and Figure 3 As shown, the stirring device in the embodiment of the present invention includes a stirring rod 1, a flexible covering layer 2 and a pulsator 3. Figure 2The structure shown in FIG. 1 does not show the flexible coating layer, but only shows the structure of the stirring rod 1. Figure 6 FIG. 1 is a schematic diagram showing a structure in which a stirring device 100 is arranged in a washing device. Figure 6 Taking a washing machine as an example, the washing device in the embodiment of the present invention includes a barrel body 5 and a stirring device 100. The barrel body 5 has a accommodating cavity 51 with an opening at one end. The stirring device 100 is detachably arranged at the end of the accommodating cavity 51 away from the opening. The stirring device 100 includes a impeller 3, a stirring rod 1 and a flexible covering layer 2. The impeller 3 is rotatably connected to the barrel body 5.

[0042] In some embodiments, the stirring device 100 is detachably connected to the barrel body 5. Removability means that the stirring device 100 can be manufactured as an independent spare part, and the production and manufacturing of the stirring device 100 can be separated from the barrel body 5. When the washing equipment is in normal use, the stirring device 100 is connected to the barrel body 5, and the stirring device 100 can move relative to the barrel body 5, thereby driving the clothes in the barrel body 5 to move, so as to simulate the rubbing action of the clothes.

[0043] The stirring device 100 in the embodiment of the present invention comprises an impeller 3, a stirring rod 1 and a flexible covering layer 2. The impeller 3 is rotatably connected to the barrel 5, and the stirring rod 1 can be a columnar structure.

[0044] Combination Figure 1 and Figure 2 As shown, when the stirring rod 1 and the impeller 3 are assembled for use, the lower end of the stirring rod 1 is detachably connected to the impeller 3, that is, the stirring rod 1 and the impeller 3 can be processed and manufactured separately, and the stirring rod 1 and the impeller 3 can be used as a whole after being matched and connected. Among them, the position where the stirring rod 1 and the impeller 3 are matched and connected is not provided with a flexible coating layer, so that the hard material of the stirring rod 1 itself is in contact and connected with the hard material of the impeller 3, which is beneficial to improve the strength of the connection. In some embodiments, the stirring device also includes a decorative cover 4, which is detachably connected to the upper end of the stirring rod 1 to close the opening at the upper end of the stirring rod 1. The embodiment of the present invention does not limit the material and structure of the decorative cover 4.

[0045] In the embodiment of the present invention, Figure 2As shown, the stirring rod 1 includes a rod body 11 and a blade 12. The rod body 11 extends in the axial direction. In some embodiments, the rod body is roughly set to a cylindrical shape, which is conducive to improving the processing efficiency. In addition, the cylindrical structure is symmetrical, which is conducive to reducing the collision and noise generated by the eccentric motion, thereby improving the structural strength of the stirring rod 1. One end of the rod body 11 in the axial direction is detachably connected to the impeller 3. The blade 12 is arranged on the surface of the circumference of the rod body 11, wherein the surface of the circumference of the rod body 11 represents the surface arranged around the axial direction in the rod body 11, and the surface of the circumference can be understood as the side of the rod body 11, rather than the relative end face arranged in the axial direction of the rod body 11. Specifically, the rod body 11 has an end face and a side face, the end face represents the face perpendicular to the axial direction, and the side face is the surface in the axial direction around the rod body 11. In the embodiment of the present invention, a plurality of blades 12 can be provided, and the plurality of blades 12 are arranged at intervals in the circumferential direction of the rod body 11. During the use of the stirring device, the protruding blades 12 are contacted and rubbed with the object to be cleaned to achieve the rubbing effect of the object to be cleaned. The embodiment of the present invention does not limit the specific shape of the blade 12. For example, the blade 12 may be a flat plate or a curved surface.

[0046] In some embodiments, the blades 12 are curved, that is, the blades are arc-shaped parts. The embodiments of the present invention configure the blades as arc-shaped parts, which is beneficial for reducing the wear of the blades on clothes and can also better stir the water flow, thereby ensuring the quality of cleaning.

[0047] The flexible covering layer 2 at least covers the outer side of the blade 12. It should be noted that at least covering the outer side of the blade 12 means that the flexible covering layer 2 can cover the outer side of the blade 12, or can cover the inner and outer sides of the blade 12, or can cover the inner and outer sides of the blade 12 and penetrate the inner and outer sides of the blade 12. Of course, it also includes that the flexible covering layer 2 covers the outer side of the rod body 11 and / or the inner side of the rod body 11 in addition to covering the outer side of the blade 12.

[0048] An embodiment of the present invention provides a washing device, which includes a barrel body and a stirring device. The barrel body has a receiving cavity, and the stirring device is detachably arranged in the receiving cavity. The stirring device includes a pulsator, a stirring rod and a flexible coating layer. The pulsator is rotatably connected to the barrel body. The stirring rod includes a rod body and blades. The rod body extends along the axial direction, and one end of the rod body in the axial direction is detachably connected to the pulsator. The blades are provided with convex surfaces relative to the circumferential direction of the rod body, and the flexible coating layer at least covers the outside of the blades. In the embodiment of the present invention, the flexible coating layer is provided at least on the outside of the blades, so that the stirring device ensures structural strength and rotational stability, while at least the surface texture of the blades is soft, which can simulate the force of human hands to rub clothes, so that the rubbing of clothes during the washing process is more uniform, and the flexible coating layer covering the outside of the stirring rod has a certain buffering effect on the stirring action of the water flow, which is beneficial to reducing the wear on the clothes, thereby helping to extend the service life of the clothes. Furthermore, in the embodiment of the present invention, a flexible covering layer is provided on the outer side of at least the blades of the stirring device, and the stirring device and the barrel body are detachable, which can not only reduce the wear of clothes, but also has a simple manufacturing process and high integration. The stirring device is suitable for existing washing equipment and can be interchangeable with the impeller in traditional washing equipment. There is no need to add new computer board software and hardware, thus saving development time and cost.

[0049] In some embodiments, Figure 4 As shown, the interior of the stirring rod 1 is hollow. It should be noted that the term "hollow" means that the stirring rod 1 is a hollow component, and the stirring rod 1 is generally a component with uniform wall thickness. The wall thickness of the stirring rod 1 refers to the thickness between the inner and outer sides of the stirring rod 1. The blade 12 is also a hollow component with uniform wall thickness, rather than a solid component. The flexible coating layer 2 covers at least the inner and outer sides of the blade 12. Figure 4 As shown, the flexible coating layer 2 can only cover the inner and outer sides of the blade 12, and the flexible coating layer 2 can also cover both the inner and outer sides of the blade 12 and the inner and outer sides of the rod body 11. It should be noted that the coating in the embodiment of the present invention means that the flexible coating layer 2 is located on the inner side of the stirring rod 1 and the outer side of the stirring rod 1, and the flexible coating layer 2 is attached to the inner and outer surfaces of the stirring rod 1 to form a tight connection relationship. Among them, the stirring rod 1 is hollow, that is, the blade 12 can be hollow, so that the blade 12 is roughly a thin-walled part (of course, the embodiment of the present invention does not limit the thickness of the blade), the inner side of the blade 12 represents the side facing the hollow area of ​​the blade 12, and the outer side of the blade 12 represents the side away from the hollow area of ​​the blade 12; the rod body 11 is also hollow, so that the rod body 11 is roughly a thin-walled part (of course, the embodiment of the present invention does not limit the thickness of the rod body), the inner side of the rod body 11 represents the side facing the hollow area of ​​the rod body 11, and the outer side of the rod body 11 represents the side away from the hollow area of ​​the rod body 11.

[0050] The embodiment of the present invention covers the flexible covering layer 2 at least on the inner and outer sides of the blade, which is conducive to the integrated setting of the flexible covering layers on the inner and outer sides, thereby improving the stability of the connection between the flexible covering layer and the stirring rod and reducing the risk of the flexible covering layer falling off.

[0051] In some embodiments, Figure 2-4 As shown, a through hole 10 is provided on the stirring rod 1, and the through hole 10 passes through the inner and outer sides of the blade 12. The through hole 10 connects the inside and the outside of the blade 12. Figure 2 In the embodiment shown in , the stirring rod 1 is hollow inside, and the through hole 10 connects the hollow area inside the stirring rod 1 and the outside of the stirring rod 1. And the flexible coating layer 2 is set through the through hole 10. The flexible coating layer 2 passing through the through hole 10 means that the flexible coating layer 2 fills and passes through the through hole 10, and the through hole 10 plays a role in connecting the flexible coating layers 2 on the inner and outer sides of the blade 12, so that the flexible coating layers 2 on the inner and outer sides can be connected to each other. The through holes 10 in the embodiment of the present invention are arranged in plurality, that is, the number of the through holes 10 can be 1 or more than 1. In the case where the through holes 10 are also arranged on the rod body 11, the through holes 10 pass through the inner and outer sides of the rod body 11. The number of the through holes 10 in the embodiment of the present invention can be determined according to the size of the rod body 11 and the blade 12 and the change or position of the structural curvature. For example, when the rod body 11 and the blade 12 are relatively large, the number of through holes 10 may be increased, or the density of through holes may be greater at a location where the curvature of the stirring rod changes greatly (e.g., the end of the blade 12 away from the rod body 11, or the location where the blade 12 is connected to the rod body 11) than at a location where the curvature changes less. The embodiment of the present invention increases the connection strength between the flexible coating layers on the inner and outer sides of the location where the curvature changes greatly by increasing the density of through holes, thereby facilitating the improvement of the stability of the connection between the flexible coating layer and the stirring rod.

[0052] The greater the number of through holes 10 , the stronger the stability of the connection between the rod body 11 or the blade 12 and the flexible covering layer 2 .

[0053] The embodiment of the present invention provides a through hole on the stirring rod so that the flexible covering layer not only covers the inner and outer sides of the blade or the rod body, but also utilizes the through hole to realize the connection of the flexible covering layers on the inner and outer sides. The flexible covering layers on the inner and outer sides can be tightly covered on the surface of the blade or the rod body, and the flexible covering layers passing through the through hole connect the flexible covering layers on the inner and outer sides, so that a stable connection relationship is formed between the flexible covering layers on the inner and outer sides, which is beneficial to enhancing the adhesion strength between the flexible covering layer and the blade or the rod body, reducing the risk of the flexible covering layer falling off relative to the blade or the rod body, and extending the service life of the stirring device.

[0054] In some embodiments, in combination Figure 1-Figure 4As shown, the stirring rod 1 and the flexible coating layer 2 are integrally formed by two-color injection molding, wherein the hardness of the flexible coating layer 2 is less than the hardness of the stirring rod 1. Specifically, the stirring rod 1 and the flexible coating layer 2 in the embodiment of the present invention are formed by two different materials, and the structural hardness of the flexible coating layer 2 is less than the hardness of the stirring rod 1. In some embodiments, the flexible coating layer 2 is set to a flexible material such as thermoplastic polyurethane elastomer (TPU), so that the flexible coating layer 2 has strong elasticity, wear resistance and toughness. In the embodiment of the present invention, by setting the flexible coating layer 2 as a flexible material, during the use of the stirring device, the flexible coating layer 2 on the outside of the stirring rod 1 contacts the object to be cleaned, and has a certain elasticity, which is conducive to reducing the impact and wear on the object to be cleaned, and improving the integrity of the object to be cleaned itself. The flexible coating layer 2 and the stirring rod 1 in the embodiment of the present invention are injected twice by a two-color injection molding machine, and the flexible coating layer 2 and the stirring rod 1 are bonded and compatible with two compatible materials with different hardness, and compatibility is achieved during the processing process. The embodiment of the present invention realizes the integral injection molding of the stirring rod 1 and the flexible covering layer 2 by two-color injection molding, which is beneficial to reducing the material cost of the entire stirring device while improving the production efficiency of the entire stirring device. For the mold for processing the stirring device, the problem of the two molds of the stirring rod 1 and the flexible covering layer 2 that cannot be mass-produced due to the particularity of the structure is solved. The two-color injection molding is used to process the stirring rod 1 and the flexible covering layer 2, thereby eliminating the assembly process of the stirring rod 1 and the flexible covering layer 2, reducing the joint between the stirring rod 1 and the flexible covering layer 2, and improving the connection strength between the stirring rod 1 and the flexible covering layer 2, thereby enhancing the wear resistance of the stirring device and extending the service life of the stirring device.

[0055] In some embodiments, Figure 5As shown, the diameter of the through hole 10 is greater than or equal to 1 mm and less than or equal to 3 mm. It should be noted that the embodiment of the present invention does not limit the cross-sectional shape of the through hole 10, wherein the cross section of the through hole 10 represents the cross section of the through hole 10 perpendicular to the extension direction, and the extension direction of the through hole 10 represents the direction of the through hole passing through the inner and outer sides. When the through hole 10 is set on the blade 12, the extension direction of the through hole 10 is the thickness direction of the blade 12, and when the through hole 10 is set on the rod body 11, the extension direction of the through hole 10 is the direction of passing through the inner and outer sides of the rod body 11. The cross-sectional shape of the through hole can be circular. The diameter of the through hole 10 defined in the embodiment of the present invention represents the diameter of the cross section of the through hole 10. When the cross section of the through hole 10 is circular, the diameter of the through hole 10 is the diameter of the circular cross section. When the cross section of the through hole 10 is non-circular, the diameter of the through hole 10 is the diameter of the equivalent circle of the through hole, wherein the equivalent circle represents a circle with the same area as the cross section of the through hole, and the equivalent diameter of the through hole 10 is calculated by the equivalent circle. It should be noted that, when the wall thickness of the stirring rod 1 is constant, the larger the diameter of the through hole 10, the larger the corresponding volume of the through hole 10, and the stronger the connection strength of the flexible coating layer 2 at the through hole 10 to the flexible coating layer 2 on both sides of the inner and outer sides. However, when the diameter of the through hole 10 is too large, during the injection molding process, the material after filling the mold starts to cool and solidify from the outer surface, and the volume shrinkage is difficult to supplement, which easily causes shrinkage in the through hole 10, thereby forming a seam between the stirring rod and the flexible coating layer, affecting the connection strength and service life of the stirring device. The embodiment of the present invention limits the diameter of the through hole 10 to the range of 1mm-3mm, which can not only improve the connection strength of the flexible coating layers inside and outside the stirring rod, but also reduce the risk of shrinkage in the through hole, which is beneficial to improving the overall quality of the stirring device.

[0056] It should be noted that the diameter of the through hole 10 in the embodiment of the present invention can be set to 1.5 mm, 1.8 mm, 2 mm, etc. By setting the diameter of the through hole 10 to the above parameter value, it is helpful to improve the quality of the entire stirring device.

[0057] In some embodiments, Figure 2As shown, the cross section of the through hole 10 is circular. In the embodiment of the present invention, the cross section of the through hole 10 is set to be circular, and the through hole 10 is set to a cylindrical structure, and the diameter of the through hole 10 is consistent in the inner and outer directions of the stirring rod 1. The stress of the flexible coating layer formed at each position in the through hole 10 after injection molding is uniform, and it is not easy to produce stress concentration, which is beneficial to improve the structural stability of the flexible coating layer. When the cross section of the through hole 10 is set to a square or other shape, due to the difference in the distance from the cross section to the center, the flexible coating layer injection molded in the through hole 10 is prone to stress concentration, and it is easy to break when impacted at the position where the stress is concentrated, thereby affecting the service life of the flexible coating layer.

[0058] In some embodiments, Figure 4 As shown, the flexible coating layer 2 includes an inner layer 21, an outer layer 22 and a connecting column 23. The inner layer 21 of the flexible coating layer 2 is coated on the inner side of the stirring rod 1, and the inner side of the stirring rod 1 can be understood as the inner side of the blade 12 and / or the inner side of the rod body 11 described in the above embodiment. The outer layer 22 is coated on the outer side of the stirring rod 1, and the outer side of the stirring rod 1 can be understood as the outer side of the blade 12 and / or the outer side of the rod body 11 described in the above embodiment. And the outer side faces the outside, and when the stirring device is in use, the outer side of the stirring rod 1 is the side facing the object to be cleaned. The connecting column 23 passes through the through hole 10 and connects the inner layer 21 and the outer layer 22. The connecting column 23 in the embodiment of the present invention is integrally formed with the inner layer 21 and the outer layer 22, and the connecting column 23 connects the inner layer 21 and the outer layer 22, which can not only improve the structural strength of the entire flexible covering layer 2, but also improve the connection strength between the flexible covering layer 2 and the stirring rod 1. The flexible covering layer 2 is not easy to fall off the stirring rod 1, thereby extending the service life of the stirring device.

[0059] In some embodiments, Figure 4As shown, the thickness of the inner layer 21 of the flexible coating layer 2 is less than the thickness of the outer layer 22 of the flexible coating layer 2. The thickness of the outer layer 22 of the flexible coating layer 2 is set evenly, and the thickness of the inner layer 21 of the flexible coating layer 2 is set evenly. The thickness of the inner layer 21 of the flexible coating layer 2 is thinner than the thickness of the outer layer of the flexible coating layer 2. The outer layer 22 of the flexible coating layer 2 is the part of the flexible coating layer 2 that contacts the object to be cleaned. The thickness of the outer layer 22 of the flexible coating layer 2 is set thicker, which is conducive to improving the elasticity and softness of the outer layer 22, so that it is easy to reduce the wear of the outer layer 22 of the flexible coating layer on the object to be cleaned during the use of the stirring device. In addition, the thickness of the outer layer 22 is thicker, and during the production process, the molding flow shape of the outer layer 22 is higher, which is conducive to improving the processing quality. In the embodiment of the present invention, by setting the thickness of the inner layer 21 of the flexible covering layer 2 to be smaller than the thickness of the outer layer 22 of the flexible covering layer 2, the inner layer 21 of the flexible covering layer 2 does not need to contact the object to be cleaned, and therefore, does not require high softness and elasticity. On the premise of ensuring that the inner layer 21 of the flexible covering layer 2 can form a connection relationship with the outer layer 22 through the connecting column 23, the processing consumables of the inner layer of the flexible covering layer 2 can also be reduced, thereby helping to reduce the processing cost and molding cycle of the entire stirring device.

[0060] In some embodiments, Figure 5 As shown, the thickness L1 of the inner layer 21 of the flexible covering layer 2 is 1 mm-1.8 mm. For example, the thickness L1 of the inner layer 21 of the flexible covering layer 2 in the embodiment of the present invention is set to 1.5 mm, and the thickness L2 of the outer layer 22 of the flexible covering layer 2 is 1.8 mm-2.5 mm. For example, the thickness of the flexible covering layer 2 is set to 2 mm, wherein the thickness of the inner layer 21 of the flexible covering layer 2 can be set to be less than the thickness of the outer layer 22. The embodiment of the present invention limits the thickness of the inner layer 21 and the outer layer 22 of the flexible covering layer 2 within a certain range, thereby improving the flexibility of the contact between the stirring device and the object to be cleaned, reducing the wear of the object to be cleaned during the cleaning process, reducing the production cost of the stirring device, and improving the efficiency of processing and molding.

[0061] In some embodiments, Figure 2 As shown, a plurality of through holes 10 are provided on the blade 12, wherein the embodiment of the present invention divides the through holes on the blade 12 into two types, namely, a first through hole and a second through hole, wherein the first through hole is provided at a position on the blade 12 away from the rod body 11, and the second through hole is provided at other positions on the blade 12. It should be noted that Figure 2 The layout of the through holes 10 shown in FIG. 1 is only for structural illustration. Figure 2Parameters such as the spacing between through holes and the size of through holes arranged therein will not limit the embodiments of the present invention, wherein the diameter of the first through hole in the embodiments of the present invention is greater than the diameter of the second through hole, or the density between the first through holes is greater than the density between the second through holes, that is, the diameter of the first through hole at the position where the blade 12 on the stirring rod 1 is away from the rod body 11 is greater than the diameter of the second through hole at other positions. It should be noted that one end of the blade 12 is connected to the rod body 11, and the other end of the blade 12 is away from the rod body 11. During the use of the stirring device, the frequency and intensity of contact with the object to be cleaned at this position are relatively large. The embodiments of the present invention increase the connection strength between the outer layer 22 and the inner layer 21 of the flexible coating layer 2 within the region by setting the diameter of the first through hole within the region to be greater than the diameter of the second through hole at other positions, thereby improving the wear resistance of the outer layer 22 of the flexible coating layer 2 in the region and reducing the risk of warping of the outer layer 22 in the region due to friction.

[0062] In some embodiments, Figure 2 As shown, in the embodiment of the present invention, the density between the first through holes is greater than the density between the second through holes, that is, the number of first through holes per unit area in the region is greater than the number of second through holes per unit area in other regions. Or it can be understood that the spacing of the first through holes in the region is smaller than the spacing of the second through holes in other regions. In the embodiment of the present invention, by making the density of the first through holes at the position where the blades 12 on the stirring rod 1 are away from the rod body 11 greater than the density of the second through holes at other positions, it is beneficial to increase the connection strength between the outer layer 22 and the inner layer 21 of the flexible coating layer 2 in the region, thereby improving the wear resistance of the outer layer 22 of the flexible coating layer 2 in the region and reducing the risk of the outer layer 22 in the region warping due to friction.

[0063] In some embodiments, Figure 2As shown, in the case where a through hole is also provided on the rod body 11, the embodiment of the present invention divides the through holes on the rod body 11 into two types, namely, a third through hole and a fourth through hole, wherein the third through hole is provided at a position on the rod body 11 close to the blade 12, and the fourth through hole is provided at other positions on the rod body 11, wherein the diameter of the third through hole in the embodiment of the present invention is greater than the diameter of the fourth through hole, that is, the diameter of the third through hole at the position of the rod body 11 close to the blade 12 is greater than the diameter of the fourth through hole at other positions. During the use of the stirring device, the blade 12 is more likely to contact the object to be cleaned than the rod body 11, and the blade 12 transmits the received stress to the rod body 11. Due to the large change in curvature at the connection between the rod body 11 and the blade 12, the stress at this position is more concentrated. Therefore, by making the diameter of the third through hole provided at the position where the blade 12 is connected to the rod body 11 greater than the diameter of the fourth through hole at other positions, it is beneficial to enhance the connection strength between the flexible coating layer and the stirring rod at the position of the area, and reduce the risk of the flexible coating layer warping.

[0064] In some embodiments, Figure 2 As shown, the density of the third through holes at the position of the rod body 11 close to the blade 12 (which can be understood as the position where the rod body 11 and the blade 12 are connected) is greater than the density of the fourth through holes at other positions of the rod body 11. In other words, the number of third through holes set per unit area within the region is greater than the number of fourth through holes set per unit area in other regions. Or it can be understood that the spacing of the third through holes in the region is smaller than the spacing of the fourth through holes in other regions. In the embodiment of the present invention, by making the density of the third through holes at the position where the blade 12 and the rod body 11 on the stirring rod 1 greater than the density of the fourth through holes at other positions, it is beneficial to increase the connection strength between the outer layer 22 and the inner layer 21 of the flexible covering layer 2 within the region and reduce the risk of warping of the outer layer 22 in the region.

[0065] In some embodiments, Figure 2As shown, the spacing between the first through holes at the position where the blade 12 is away from the rod body 11 and / or the third through holes at the position where the blade 12 is connected to the rod body 11 can be equal, and the spacing between the second through holes can be equal to the spacing between the fourth through holes. In some embodiments, the spacing between the third through holes or the spacing between the fourth through holes can be set to 8mm-15mm; the range described by the above two positions is consistent with the range described in the above embodiments, that is, the friction intensity between the flexible coating layer within the above two areas and the external object to be cleaned is relatively large, or the stress concentration is formed inside the stirring rod due to structural changes. Therefore, the spacing between the through holes in the above two areas is set to 8mm-15mm, and the spacing between the through holes at other positions on the stirring rod 1 (such as the second through hole or the fourth through hole) is set to 15mm-25mm. The smaller the spacing between the through holes, the stronger the connection stability between the inner layer and the outer layer, which is conducive to improving the structural strength and wear resistance of the flexible coating layer.

[0066] The present invention provides a washing device, which includes a stirring device as described in any of the above embodiments. The present invention provides a stirring device as described in any of the above embodiments in the washing device, and the stirring device provides a through hole on the stirring rod, so that the flexible coating layer is connected to the inside and outside of the blade 12 or the rod body 11 by using the through hole on the stirring rod. The flexible coating layers on the inside and outside of the blade 12 or the rod body 11 can be tightly coated on the surface of the blade 12 or the rod body 11, and the flexible coating layers passing through the through hole play a role in connecting the flexible coating layers on the inside and outside, so that a stable connection relationship is formed between the flexible coating layers on the inside and outside, which is conducive to enhancing the adhesion strength between the flexible coating layer and the stirring rod, reducing the risk of the flexible coating layer falling off relative to the stirring rod, and extending the service life of the stirring device. In addition, during the cleaning process of the washing device, the stirring device contacts the object to be cleaned, which is conducive to reducing the risk of the stirring device being worn by the cleaning object.

[0067] It should be noted that the washing equipment in the embodiments of the present invention includes but is not limited to washing machines, dishwashers, shoe washers and fruit and vegetable cleaning machines. By applying a stirring device to the washing equipment, the washing efficiency and cleaning degree of the washing equipment can be improved. Figure 6As shown, the following describes the application of the stirring device in a washing machine as an example. The washing machine includes a barrel 5, and a receiving chamber 51 for receiving clothes to be cleaned is provided in the barrel 5. The stirring device 100 is arranged in the receiving chamber 51. During the processing of clothes, the stirring device 100 contacts the clothes to be cleaned. By setting the stirring device 100 described in any of the above embodiments, during the cleaning process, the stirring device 100 can make a reciprocating rotation relative to the barrel 5, which can simulate the rubbing of the clothes in the receiving chamber 51 by human hands. The stirring device is also provided with a pulsator 3, which is connected to the stirring rod. The size of the pulsator 3 in the embodiment of the present invention can be set to be consistent with the pulsator of the existing washing machine product, which is more conducive to adapting the stirring device in the embodiment of the present invention to the existing washing machine model, and can realize the replacement of the pulsator in the existing model, so as to conveniently realize the layout of differentiated products. In addition, it can be driven and operated without changing the layout of existing computer software, hardware, clutch, motor and other equipment, which is conducive to saving development time and cost.
