[0024] It should be noted that in the description of the present invention, the terms "inside", "outside", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0025] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "connection", "setting", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, etc. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0026] In order to solve the problem that the brush structure connected to the impeller by thread connection is easy to loosen or even detach during the washing process, Figure 1As shown, the present invention provides a pulsator for a washing device, the pulsator for a washing device comprises a pulsator body 1 and a brush portion 2, the pulsator body 1 is provided with a pulsator body connecting member 11, the brush portion 2 comprises a brush portion body 21 and a brush connecting member 22 arranged on the brush portion body 21; the brush connecting member 22 is detachably connected to the pulsator body connecting member 11, and the pulsator further comprises a limiting portion 3; the limiting portion 3 is arranged as follows: when the pulsator rotates, the limiting portion 3 can prevent the brush portion 2 and the pulsator body 1 from rotating relative to each other.
[0027] Specifically, the impeller body connector 11 (in the present embodiment, the impeller body connector 11 is an internal thread connector) and the brush connector 22 (in the present embodiment, the brush connector 22 is an external thread connector) are threadedly connected.
[0028] The limiting part 3 includes an impeller body limiting member 32 and a brush limiting member 31. The impeller body limiting member 32 is fixedly arranged on the impeller body 1, and the brush limiting member 31 is fixedly arranged on the brush body 21. Through the joint action of the impeller body limiting member 32 and the brush limiting member 31, the brush part 2 and the impeller body 1 do not rotate relative to each other. One of the impeller body limiting member 32 and the brush limiting member 31 is a groove, and the other is a telescopic limiting structure. In this embodiment, the impeller body limiting member 32 is a telescopic limiting structure, and the brush limiting member 31 is a groove. The telescopic limiting structure includes: a receiving groove 321, a limiting block 322 that is telescopically arranged in the receiving groove 321, and an elastic member 323 arranged in the receiving groove 321, and the elastic member 323 can drive the limiting block 322 to move in the direction of extending out of the receiving groove 321.
[0029] The impeller further includes an action block 4 and an action channel 5. The action block 4 is arranged in the action channel 5. The action channel 5 penetrates the brush body 21 and enters the impeller body 1. A limit block connector 324 is also fixedly arranged on the limit block 322, and the limit block connector 324 is slidably arranged on the action channel 5; the action block 4 is fixedly connected or abutted with the limit block connector 324. When the brush part 2 is installed, as the brush part 2 is installed, the brush part 2 will squeeze the limit block 322 and make it enter the receiving groove 321. When the brush part 2 is installed, the brush limit member 31 (groove) is aligned with the limit block 322, and the limit block 322 enters the brush limit member 31 to achieve the limit. When the brush part 2 needs to be removed, the action block 4 is pressed, and the action block 4 moves along the action channel 5, and the limit block 322 is moved downward through the limit block connector 324. At this time, the brush part 2 can be removed by rotation.
[0030] In summary, the impeller for washing device of the present invention can limit the brush part 2 by the limiting part 3, thereby preventing the brush part 2 from rotating relative to the impeller body 1. In this way, during the impeller washing rotation process, the present invention can significantly reduce the possibility of loosening or even separation between the brush part 2 and the impeller body 1.
[0031] It should be noted that the above embodiments are only used to illustrate the principles of the present invention and are not used to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structures through other replaceable implementations so that the present invention can be applied to more specific application scenarios. These do not deviate from the principles of the present invention and therefore will fall within the scope of protection of the present invention.
[0032] For example, in an alternative embodiment, the impeller body connector 11 recorded in the embodiment before the structural adjustment above can be an internal thread connector, and the brush connector 22 can be an external thread connector, which can be replaced by:
[0033] The impeller body connector 11 is an external thread connector, and the brush connector 22 is an internal thread connector (not shown in the figure). These do not deviate from the principle of the present invention, and therefore will fall within the protection scope of the present invention.
[0034] For example, in another alternative embodiment, the impeller body connector 11 recorded in the embodiment before the structural adjustment above can be an internal thread connector, and the brush connector 22 can be an external thread connector, which can be replaced by:
[0035] One of the impeller body connector 11 and the brush connector 22 is a protrusion, and the other is a recessed hole 111 and a slideway 112; the brush connector 22 enters the impeller body connector 11. Specifically, in this embodiment, Figure 2-3 As shown, the brush connector 22 is a protrusion, and the impeller body connector 11 is a recessed hole 111 and a slideway 112 for illustration (in other embodiments, the protrusion, the recessed hole and the slideway may also be interchanged).
[0036] The slideway 112 is communicated with the recessed hole 111 . Figure 2 After the brush part 2 in the middle is rotated horizontally by 90 degrees, the brush connecting member 22 is aligned with Figure 3 The brush connector 22 is moved downward to the bottom along the slideway 112, and then the brush part 2 is horizontally rotated so that the brush connector 22 enters the impeller body connector 11. These do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.
[0037] For example, in another alternative embodiment, based on the structure in the previous alternative embodiment, further:
[0038] The limiting part 3 is replaced by: the impeller body limiting member 32 is fixedly arranged on the impeller body connecting member 11 (not shown in the figure), and the brush limiting member 31 is fixedly arranged on the brush connecting member 22 (not shown in the figure). One of the impeller body limiting member 32 and the brush limiting member 31 is a buckle, and the other is a slot, and the buckle is engaged with the slot. In this embodiment, it is equivalent to setting a slot and a buckle inside the impeller body connecting member 11 and at the end of the brush connecting member 22 respectively. These do not deviate from the principle of the present invention, and therefore will fall within the protection scope of the present invention.
[0039] For example, in another alternative embodiment, the impeller body limiting member 32 in the embodiment before the structural adjustment described above may be a telescopic limiting structure, and the brush limiting member 31 may be a groove, which may be replaced by:
[0040] The impeller body limiter 32 is a groove, and the brush limiter 31 is a telescopic limiter structure (not shown in the figure). Correspondingly, the impeller also includes an action block 4 and an action channel 5, the action block 4 is arranged in the action channel 5, and the action channel 5 is arranged in the brush body 21. A limit block connector 324 is also fixedly arranged on the limit block 322, and the limit block connector 324 is slidably arranged on the action channel 5; the action block 4 is fixedly connected to the limit block connector 324. These do not deviate from the principles of the present invention, and therefore will fall within the protection scope of the present invention.
[0041] For example, in another alternative embodiment, the impeller body limiting member 32 in the embodiment before the structural adjustment described above may be a telescopic limiting structure, and the brush limiting member 31 may be a groove, which may be replaced by:
[0042] One of the impeller body limiter 32 and the brush limiter 31 is a magnet (not shown in the figure), and the other is a magnet or ferromagnetic material (not shown in the figure). These do not deviate from the principle of the present invention, and therefore will fall within the protection scope of the present invention.
[0043] For example, in another alternative implementation, based on the structure recorded in the above embodiment before the structural adjustment, further:
[0044] The brush body 21 is an air bag, the brush limiter 31 is an air hole, and the impeller body limiter 32 includes an air pipe (in the present embodiment, the impeller body limiter 32 is the telescopic limiter structure described above, and the limiter block 322 is an air pipe). The impeller also includes an impeller shaft (not shown in the figure), which is fixedly connected to the impeller body 1; an air supply channel is arranged inside the impeller shaft (not shown in the figure, which is equivalent to arranging a pipeline in the axial direction of the impeller shaft). Under the joint action of the impeller body limiter 32 and the brush limiter 31, when there is no relative rotation between the brush part 2 and the impeller body 1, the air hole is connected to the air pipe (that is, the air pipe enters the air hole). One end of the air supply channel is connected to the air pipe, and when there is no relative rotation between the brush part 2 and the impeller body 1, there is no relative rotation between the air supply channel and the air pipe. The other end of the air supply channel is connected to an external air pump (not shown in the figure, the air pump is arranged outside the washing barrel of the washing device, and the output end of the air pump is connected to the other end of the air supply channel) (in other parallel embodiments, a valve may also be arranged in the air supply channel). Accordingly, the volume of the action block 4 is reduced to a position close to the limit block connector 324 (in other parallel embodiments, the action block 4 may not be arranged to avoid interfering with the brush body 21). When the brush part 2 needs to be disassembled, a long object is used to apply force to the limit block connector 324 along the action channel 5 and then rotate the brush part 2.
[0045] In this embodiment, the brush body 21 can be expanded or contracted by supplying or exhausting air to the brush body 21 through an air pump. When the brush body 21 expands, the pulsator can wash shoes, and when the brush body 21 contracts, the pulsator can wash clothes. On this basis, when the brush part 2 needs to be disassembled for replacement or cleaning, the pulsator body connector 11 and the brush connector 22 can be disconnected by rotating. These do not deviate from the principles of the present invention, and therefore will fall within the scope of protection of the present invention.
[0046] In addition, the present invention also provides a washing device, which has a pulsator for washing devices as described in any of the above embodiments. The washing device can be a pulsator shoe washer or a pulsator washing machine. The washing device includes a washing tub (not shown in the figure).
[0047] Specifically, in one embodiment, when the brush body 21 is an air bag, the washing device can be provided with an image sensor (not shown in the figure), and the image of the object to be washed placed in the washing tub is obtained through the image sensor (such as a camera, etc.), and the image is then transmitted to a controller (not shown in the figure, the controller can be a controller provided by the washing device, or an external server, etc., connected by a wireless connection, etc.), and the controller determines the type of the object to be washed by recognizing the image. The brush body 21 is then controlled to be in a corresponding state. When the object to be washed placed in the washing tub is a shoe, the brush body 21 is controlled to be in an inflated state. When the object to be washed placed in the washing tub is a piece of clothing, the brush body 21 is controlled to be in an exhausted state.
[0048] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
