[0023] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0024] In the description of the embodiments of the present application, it should be noted that the terms "height direction", "top", "bottom" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or position relationship shown in the figure is only for the convenience of describing the embodiments of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. The present application is further described in detail below in conjunction with the drawings and specific embodiments.

[0025] The present application embodiment provides a washing device 100, see Figure 1 The washing device 100 includes a washing bucket 1 and a brush assembly 2. The washing bucket 1 has a washing chamber 11. The brush assembly 2 includes a brush shaft 21 and bristles 22. The side wall 211 and the top wall 212 of the brush shaft 21 are both provided with bristles 22. One end of the bristles 22 is connected to the brush shaft 21, and the other end extends in a direction away from the brush shaft 21. The free ends of some bristles 22 are located in the same horizontal plane and constitute the top surface of the brush assembly 2. The brush shaft 21 is rotatably connected to the washing bucket 1.

[0026] The washing tub 1 provides a storage space for washing objects, and the washing objects are confined within the range of the washing chamber 11 to be washed by friction with the brush assembly 2 .

[0027] The specific structure of the washing tub 1 is not limited here. Generally, the washing tub 1 is a cylindrical structure, and the brush assembly 2 is located at the center of the circular area at the bottom of the washing tub 1. In this way, the center of gravity of the washing device 100 is as close to the rotation center of the brush assembly 2 as possible, reducing the influence of the rotational torque and improving the working stability of the washing device 100.

[0028] In some embodiments, a plurality of protrusions are provided on the inner wall of the washing tub 1, so as to increase the friction between the wall of the washing tub 1 and the washing items, thereby improving the washing effect.

[0029] The side wall 211 is where most of the laundry items are located in the washing chamber 11, and the bristles 22 are arranged here to effectively scrub the laundry items.

[0030] During the washing process, the items to be washed may float on the water surface, and the bristles 22 arranged on the side wall 211 may not be able to act on the items to be washed. By arranging the bristles 22 on the top wall 212 of the brush shaft 21, the items to be washed floating on the water surface can be washed, and the contact area between the brush assembly 2 and the items to be washed can be increased, thereby improving the washing effect.

[0031] One end of the bristle 22 is embedded in the brush shaft 21, and the other end is extended. Here, the free end refers to the end of the bristle 22 that extends out. The free end contacts the washing object to generate friction. When the friction force is too large, the free end bends and deforms. When the force acting on the free end decreases or disappears, the free end gradually returns to its original position.

[0032] The specific form of the free ends of the bristles 22 being located in the same horizontal plane is not limited here, for example, the extension angle of the bristles 22 can be changed or the height of the bristles 22 can be controlled to form a horizontal plane, or a combination of the above two methods. Of course, the free ends of the bristles 22 can also be located in the same horizontal plane by adjusting the shape of the top of the brush shaft 21.

[0033] The top surface of the brush assembly 2 refers to the surface located on the top of the brush assembly 2 formed by the free ends of some bristles 22 .

[0034] By setting the top surface of the brush assembly 2 to a horizontal plane formed by the free ends of some of the bristles 22, when the horizontal plane contacts the washing items floating on the water surface, compared with other shapes, on the one hand, the contact area between the horizontal plane and the washing items is larger, and the force transmitted to each bristle 22 is smaller, and the bristles 22 are not easily deformed. On the other hand, compared with other shapes, when the top surface of the brush assembly 2 is set horizontally, the length of the bristles 22 is shorter, which is also conducive to improving the hardness of the bristles 22 and making them less likely to deform.

[0035] The specific material of the bristles 22 is not limited here, and any material that has a certain strength, is easy to be shaped by spinning and has a certain wear resistance can be used, for example, it can be nylon, polyurethane or polypropylene, etc.

[0036] Exemplarily, the bristles 22 are of a filamentous structure. Here, since the bristles 22 need to contact and rub against the items to be washed and rely on friction to wash away dirt, the bristles 22 need to have a certain hardness so that they are not easily deformed when subjected to friction and affect the washing effect.

[0037] The manner in which the brush shaft 21 is rotatably connected to the washing tub 1 is not limited herein, and may be, for example, a bearing connection or a shaft hole direct connection. The rotation of the brush shaft 21 drives the bristles 22 to move relative to the washing items, thereby scrubbing the washing items.

[0038] The washing device 100 provided in the embodiment of the present application has bristles 22 arranged on the top wall 212 of the brush shaft 21. On the one hand, the bristles 22 on the top wall 212 can come into contact with the washing items floating on the water surface for washing, thereby increasing the contact area with the washing items and thus improving the washing effect. On the other hand, the free ends of some of the bristles 22 arranged on the top wall 212 are located in the same horizontal plane, thereby increasing the strength of the bristles 22 on the top wall 212, reducing the deformation of the bristles 22 when washing shoes, and further improving the washing effect.

[0039] For some examples, see Figure 1 and Figure 2 The washing device 100 further includes a pulsator 3 , which is rotatably disposed at the bottom of the washing chamber 11 , and a brush shaft 21 is connected to the pulsator 3 , and the brush shaft 21 can rotate with the pulsator 3 .

[0040] The impeller 3 is a disc-shaped structure arranged at the bottom of the washing tub 1. A protrusion is arranged on the impeller 3. When the impeller 3 rotates, the protrusion drives the water flow in the washing tub 1 to rotate and roll, thereby driving the movement of the washing items, so that the relative movement between the washing items and the brush assembly 2 generates friction, thereby improving the washing effect.

[0041] The specific structure of the protrusion is not limited here. The protrusion and the impeller 3 can be an integrally formed structure, or can be manufactured separately and finally assembled into an integral structure.

[0042] For example, see Figure 2 The protrusion and the impeller 3 are an integrally formed structure. Regularly protruding long strip protruding ribs are arranged on the surface of the impeller 3 to form the protrusion. The protrusion extends from the center of the impeller 3 toward the circumference.

[0043] In some embodiments, the protrusion is manufactured separately from the impeller 3 , and the protrusion is a plurality of long strip-shaped plate-like structures, which are regularly arranged along the center of the impeller 3 in the circumferential direction.

[0044] Exemplarily, the brush shaft 21 is a columnar structure, and the bottom of the brush shaft 21 is connected to the impeller 3 and rotates with the impeller 3 .

[0045] Bristles 22 are implanted on the other surfaces of the brush shaft 21. The rotation of the brush shaft 21 drives the bristles 22 to rotate, and the bristles 22 move relative to the objects to be washed to generate friction, thereby removing dirt on the objects to be washed.

[0046] The connection method between the brush shaft 21 and the impeller 3 is not limited here. The brush shaft 21 and the impeller 3 can be an integrally formed structure, or can be manufactured separately and finally assembled into an integral structure.

[0047] For example, see Figure 2 The brush shaft 21 and the impeller 3 are manufactured separately, and the brush shaft 21 and the impeller 3 are connected into a whole by setting a connecting bayonet and a screw.

[0048] By adding the impeller 3, the water in the washing chamber 11 is driven to flow, thereby driving the movement of the washing items, increasing the relative movement speed between the washing items and the brush assembly 2, thereby improving the washing efficiency and washing effect of the washing device 100.

[0049] For some examples, see Figure 1 , Figures 3 to 5The distance between the top wall 212 of the brush shaft 21 and the top surface of the brush assembly 2 is greater than or equal to 15 mm and less than or equal to 120 mm.

[0050] It should be noted that the greater the distance between the top wall 212 of the brush shaft 21 and the top surface of the brush assembly 2, the longer the bristles 22 at the top of the brush assembly 2 are, and the larger the brushing range of the top of the bristles 22 is, but at the same time, the top of the bristle 22 assembly is softer.

[0051] The distance between the top wall 212 of the brush shaft 21 and the top surface of the brush assembly 2 is greater than or equal to 15 mm and less than or equal to 120 mm, for example, it can be 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 70 mm, 80 mm, 90 mm, 100 mm, 110 mm, 120 mm, etc.

[0052] By setting the distance between the top wall 212 of the brush shaft 21 and the top surface of the brush assembly 2 to be greater than or equal to 15 mm and less than or equal to 120 mm, the brush assembly 2 has a certain brushing range and the bristles 22 also have a certain hardness to ensure the brushing effect.

[0053] For some examples, see Figure 1 , Figures 3 to 5 The distribution density of the bristles 22 on the top wall 212 of the brush shaft 21 is greater than the distribution density of the bristles 22 on the side wall 211 of the brush shaft 21 .

[0054] It should be noted that the higher the density of the bristles 22, the harder it is for the brush assembly 2 to deform during brushing. The distribution density of the bristles 22 on the top wall 212 of the brush shaft 21 is not limited here, and is specifically determined according to the design strength of the brush assembly 2.

[0055] The bristles 22 on the top wall 212 of the brush shaft 21 are at a shorter distance from the rotation center of the brush assembly 2, and thus move a shorter distance during operation than the bristles 22 on the side wall 211 of the brush shaft 21. When the density of the bristles 22 is relatively low, the mutual support between the bristles 22 is insufficient, and when the bristles 22 contact the washing items, they deform in the direction of movement of the washing items, further reducing the relative displacement between the bristles and the washing items, and weakening the washing effect of the sliding friction of the bristles 22. By increasing the density of the bristles 22, the hardness of the bristles 22 is increased, and the degree of deformation and displacement of the bristles 22 is reduced, the washing effect is improved.

[0056] By setting the distribution density of the bristles 22 on the top wall 212 of the brush shaft 21 to be greater than the distribution density of the bristles 22 on the side wall 211 of the brush shaft 21, the bristles 22 on the top wall 212 of the brush shaft 21 support each other and are not easily deformed, so that the free end can continue to brush the washing items, thereby improving the washing effect of the washing device 100.

[0057] For some examples, see Figure 1 , Figures 3 to 5 , from the bottom to the top of the washing device 100, the brush assembly 2 includes a first area 2a and a second area 2b distributed in sequence, the bristles 22 of the first area 2a are arranged horizontally, and the bristles 22 of the second area 2b are arranged upwardly inclined.

[0058] The first area 2a and the second area 2b are distinguished by the setting angle of the bristles 22 . The specific dividing position is not limited here and is determined according to the size of the brush shaft 21 and the outer contour of the brush assembly 2 .

[0059] The bristles 22 of the first region 2a are arranged horizontally, that is, the bristles 22 are perpendicular to the surface of the brush shaft 21, which helps to reduce the difficulty of the bristle planting process.

[0060] The upward tilt angle of the bristles 22 is adjusted on the second area 2b to transition to the first area 2a, so that the overall contour surface of the bristle 22 component has a smooth transition, which is beneficial to the overall shaping of the outer contour of the brush component 2.

[0061] By dividing the brush assembly 2 into a first area 2a and a second area 2b, and by changing the arrangement of the bristles 22 in the first area 2a and the second area 2b, the free ends of the bristles 22 form brush assemblies 2 of different shapes, thereby adjusting the different washing effects of the brush assembly 2 to adapt to different washing items.

[0062] For some examples, see Figure 1 , projected on a plane perpendicular to the rotation axis of the brush shaft 21, the projections of the free ends of the bristles 22 arranged in the first area 2a are all located on the same circumference.

[0063] The arrangement of the bristles 22 on the first area 2a is not limited here and is specifically determined according to the desired washing effect of the design.

[0064] In some embodiments, in the first region 2 a , the bristles 22 have the same length and are evenly arranged perpendicular to the surface of the brush shaft 21 .

[0065] In other embodiments, on the first region 2a, the bristles 22 are arranged in groups, all the bristles 22 have the same length, the density of the bristles 22 in the same group is the same, and the bristles 22 in each group are evenly arranged on the surface of the brush shaft 21.

[0066] There is no limitation on the distribution form of each group of bristles 22. For example, they may be vertically arranged upward from the bottom to the top of the washing device 100, or they may be extended in a spiral shape from the bottom to the top of the washing device 100, and so on.

[0067] The free ends of the bristles 22 in the first area 2a are projected on the same circumference on a plane perpendicular to the rotation axis of the brush shaft 21, so that the free ends of all the bristles 22 in the first area 2a can form a flat surface, increasing the contact area with the shoes during washing. In addition, the free ends of the bristles 22 are all located on the same circumference, that is, the farthest washing range of all the bristles 22 is consistent, so that the contact probability of each bristle 22 with the washing object will not differ too much, avoiding excessive wear of the bristles 22 due to excessive protrusion of the bristles 22 in a certain area and frequent contact with the washing object.

[0068] For some examples, see Figure 1 and Figure 3 The contour shape formed by all the bristles 22 is cylindrical.

[0069] The bristles 22 together form a cylindrical outer surface, and the top surface of the brush assembly 2 is a flat circular horizontal surface. In this way, the shaping of the brush assembly 2 is convenient, and the bristles 22 on the cylindrical top surface have a stronger structural strength, are not easily deformed when washing the washing object, and improve the washing effect. At the same time, the edge of the top cylindrical surface can extend into the shoe opening of the washing object, such as a shoe, to wash the inside of the shoe.

[0070] For some examples, see Figure 1 and Figure 4 The free ends of at least some of the bristles 22 define the circumferential outer surface of the brush assembly 2, and the distance between the circumferential outer surface located in the second area 2b and the brush shaft 21 gradually increases from the bottom to the top of the washing device 100.

[0071] That is to say, the free ends of the bristles 22 in the second area 2b gradually move away from the center of the rotating axis when gradually moving upward along the direction from the bottom to the top of the washing device 100, and the circumferential outer surface forms a structure that is wide at the top and narrow at the bottom. The closer the bristle 22 component is to the upper end, the larger the brushing range.

[0072] The arrangement of the bristles 22 to form the above-mentioned wide-upper-narrow-lower structure on the circumferential outer surface is not limited here, for example, the structure can be formed by changing the extension angle of the bristles 22 or controlling the height of the bristles 22, or a combination of the above two methods. Of course, the shape of the top of the brush shaft 21 can also be adjusted.

[0073] Here, the specific arrangement of the bristles 22 in the first area 2a is not limited.

[0074] For example, see Figure 4The first area 2a of the brush assembly 2 forms a cylindrical profile along the height direction, and the bristles 22 in the second area 2b of the brush assembly 2 form a wide structure on the circumferential outer surface and a narrow structure at the bottom. This makes the profile of the bristle 22 assembly present a tree-like structure, the upper end of the tree-like structure is a truncated cone-like structure with a large bottom surface on the top and a small bottom surface on the bottom, and the lower end is a cylindrical structure.

[0075] The wide-at-top and narrow-at-bottom structure provided on the circumferential outer surface in the second region 2b improves the structural strength of the top force-bearing portion of the brush assembly 2, reduces the degree of deformation of the top, and improves the brushing effect of the top.

[0076] For some examples, see Figure 1 and Figure 5 , from the bottom to the top of the washing device 100, the distance between the circumferential outer surface and the brush shaft 21 gradually increases.

[0077] Here, the structure of the bristles 22 in the first region 2a and the second region 2b of the brush assembly 2 is similar to the structure of the second region 2b having a wide top and a narrow bottom on the circumferential outer surface in the above-mentioned embodiment.

[0078] In some embodiments, see Figure 5 The outline of the bristle 22 assembly is a truncated cone structure, and the large bottom surface of the truncated cone is located above the small bottom surface, forming a gradually transitioning structure that is wide at the top and narrow at the bottom.

[0079] In this way, it is helpful to increase the contact area with the washing items floating on the water surface and improve the washing effect. On the other hand, such arrangement of the bristles 22 is also helpful to increase the area of ​​the horizontal plane formed by the free ends of the top bristles 22, and increase the strength of the top. Moreover, such arrangement can form a thin edge at the top of the brush assembly 2, and this edge can also extend into the shoe opening when the washing items are shoes, for example, to brush the inside of the shoes. It is also helpful to reduce the difficulty of the production process, save manufacturing materials, and reduce manufacturing costs.

[0080] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application are included in the protection scope of the present application.
