The present disclosure provides a cleaning apparatus for cleaning a work surface of a floor, carpet, or the like. The cleaning device includes at least a body, a floor brush assembly, and a hand-held assembly. Wherein the body is used as a carrier for installing various functional elements required by the cleaning equipment; the floor brush assembly is disposed at the bottom of the body and is configured to clean a work surface. The ground brush assembly can comprise a ground brush frame body and a rolling brush rotatably connected to the ground brush frame body. During operation of the cleaning device, the roller brush is rotated relative to the working surface to clean the working surface.

The handheld component is arranged on the machine body and is used for being held by a user. The user may drag the cleaning device over the work surface while holding the handle assembly so that the floor brush assembly can clean around the work surface.

To facilitate cleaning of a low profile by the cleaning device, in the cleaning device of the present disclosure, the hand-held assembly is rotatably coupled to the body and is configured to rotate between a first position and a second position; when the handheld component is positioned at the first position, the extending direction of the handheld component is parallel to the thickness direction of the machine body; in the second position, the hand-held assembly is configured to not exceed the thickness of the body.

Thus, when the handheld component is positioned at the first position, the handheld component extends along the direction parallel to the thickness direction of the machine body, and the length of the handheld component in the thickness direction of the machine body is larger, and is usually larger than the thickness of the machine body; when the handheld component rotates to the second position, the length of the handheld component in the thickness direction of the machine body does not exceed the thickness of the machine body, so that the handheld component does not obstruct the cleaning equipment from entering the short space, and a user can stretch the cleaning equipment into the short space such as the bed bottom and the sofa bottom, so that the working surface in the short space is cleaned.

In the cleaning device of the present disclosure, the hand-held assembly is rotatable between a first position and a second position, and a user can adjust the position of the hand-held assembly as desired. During normal cleaning, a user can place the handheld component in the first position, so that the handle component is convenient to hold; when the low space such as the bed bottom and the sofa bottom needs to be cleaned, a user can rotate the handheld assembly to the second position, and then the cleaning equipment stretches into the low space such as the bed bottom and the sofa bottom, so that the working surface in the low space is cleaned.

It can be seen that the cleaning device of the present disclosure can extend into a low space such as a bed bottom and a sofa bottom, and clean a working surface in the low space, thereby effectively improving the use experience of a user.

For ease of understanding, the specific structure of the cleaning apparatus of the present disclosure and its principle of operation will be described in detail with reference to fig. 1 to 10 in conjunction with one embodiment.

As shown in fig. 1, 2 and 5, the present disclosure provides a cleaning apparatus for cleaning a work surface of a floor, carpet, or the like.

The cleaning device comprises at least a body 2, a brush assembly 3 and a hand-held assembly 1. Wherein the body 2 serves as a carrier for mounting various functional elements required for the cleaning apparatus;

the floor brush assembly 3 is provided at the bottom of the body 2 and is configured to clean a working surface. The ground brush assembly 3 may include a ground brush holder body and a rolling brush rotatably connected to the ground brush holder body. During operation of the cleaning device, the roller brush is rotated relative to the working surface to clean the working surface. Wherein the floor brush assembly 3 is rotatably connected to the main body 2 by repeatedly pulling the cleaning device and cleaning the work surface with the floor brush assembly 3 in order to facilitate the user's non-moving.

In particular, in one embodiment of the present disclosure, the functional components may include a wastewater tank and/or a cleaning liquid tank and/or a blower assembly. The cleaning liquid barrel is used for storing cleaning liquid sprayed to the working surface, and the cleaning liquid can be clean water or other cleaning liquids; the fan assembly is used for sucking dirt on the working face into the sewage bucket for temporary storage.

The hand-held assembly 1 is provided on the body 2 and is intended to be held by a user. The user may drag the cleaning device over the work surface while holding the handle assembly so that the floor brush assembly 3 can clean around the work surface.

To facilitate gripping of the hand-held assembly 1 by a user, as shown in fig. 1, in one embodiment of the present disclosure, the hand-held assembly 1 may include a gripping structure 11 in the form of a closed loop. When the user uses the cleaning device, the user can drag the cleaning device on the working surface by holding the holding structure 11.

In order to facilitate cleaning of a low profile by the cleaning apparatus of the present disclosure, the hand-held assembly 1 is rotatably connected to the body 2 and is configured to rotate between a first position and a second position; in the first position, the extending direction of the hand-held assembly 1 is configured to be parallel to the thickness direction of the body 2; in the second position, the hand-held assembly 1 is configured not to exceed the thickness of the body 2.

As shown in fig. 2, the thickness direction of the body 2 refers to the direction from the front side to the rear side of the body 2, i.e., the traveling direction of the cleaning apparatus when the body 2 is placed vertically, i.e., the thickness direction. The extending direction of the handheld component 1 is the direction perpendicular to the connecting structure between the handheld component 1 and the machine body in the plane of the handheld component 1.

As shown in fig. 5 to 7, when the hand-held module 1 is in the first position, the hand-held module 1 extends in a direction parallel to the thickness direction of the body 2, and the length in the thickness direction of the body 2 is relatively large, which is generally larger than the thickness of the body 2 itself. Thus, the cleaning device of the present disclosure can be placed in the first position when in the normal cleaning mode, where the angle between the machine body and the working surface is relatively large, typically greater than 30 °, and the hand-held assembly 1 extends in a direction parallel to the thickness direction of the machine body 2, so that the user can hold the cleaning device to repeatedly pull the cleaning device, and clean the working surface.

As shown in fig. 8 to 10, when the hand-held assembly 1 rotates to the second position, the length of the hand-held assembly 1 in the thickness direction of the body 2 does not exceed the thickness of the body 2, so that the hand-held assembly 1 does not obstruct the cleaning device from entering the short space, and a user can extend the cleaning device into the short space such as the bed bottom and the sofa bottom, thereby cleaning the working surface in the short space.

In particular, in one embodiment of the present disclosure, the cleaning apparatus is configured such that the hand-held assembly 1 is in the second position when in the lie-flat cleaning mode. At this point, the user can rotate the body 2 relative to the floor brush assembly 3 to an angle of less than 20 ° with the work surface. Specifically, when the user needs to clean the low space, the handheld assembly 1 can be located at the second position, and the machine body 2 is further lowered until the included angle between the machine body 2 and the working surface is smaller than 20 degrees, so that the machine body 2 is close to the working surface, and the user can conveniently extend the cleaning device into the low space, so that the working surface in the low space is cleaned.

It will be appreciated that when the cleaning apparatus is in the lying cleaning mode, the main body is substantially parallel to the working surface, but not exactly parallel, and the main body is at a small angle between the working surfaces at all times, which angle may be 20 ° or 10 °, and the specific angle values may be set as required.

In the cleaning device of the present disclosure, the hand-held assembly 1 is rotatable between a first position and a second position, and the user can adjust the position of the hand-held assembly 1 as desired. During normal cleaning, the user can place the hand-held assembly 1 in the first position, thereby facilitating gripping of the handle assembly; when the low space such as the bed bottom and the sofa bottom needs to be cleaned, the user can rotate the handheld assembly 1 to the second position, and then the cleaning equipment stretches into the low space such as the bed bottom and the sofa bottom, so that the working surface in the low space is cleaned.

It can be seen that the cleaning device of the present disclosure can extend into a low space such as a bed bottom and a sofa bottom, and clean a working surface in the low space, thereby effectively improving the use experience of a user.

As shown in fig. 2, in one embodiment of the present disclosure, two second positions are provided, and the two second positions are located at both sides of the first position, respectively. Thus, the user can position the handheld assembly 1 in the second position more convenient to hold according to the hand used for holding the handheld assembly 1, so that the use experience of the user is improved.

Further, as shown in fig. 2, in one embodiment of the present disclosure, the hand-held assembly 1 is configured to rotate counter-clockwise relative to the body 2 to a second position and/or to rotate clockwise relative to the body 2 to a second position. It will be appreciated that the hand-held assembly 1 may be configured to rotate only counter-clockwise or clockwise with respect to the body 2 to the second position, or may be configured to rotate both counter-clockwise and clockwise with respect to the body 2 to the second position. When two or more second positions are provided, the hand-held assembly 1 may also be configured to rotate counter-clockwise with respect to the body 2 to a partial second position, or clockwise with respect to the body 2 to another second position.

To reduce the required rotation travel, taking the direction of fig. 2 as an example, the user may rotate the handheld assembly 1 counterclockwise when the user needs to rotate the handheld assembly 1 to the second position on the left, and the user may rotate the handheld assembly 1 clockwise when the user needs to rotate the handheld assembly 1 to the second position on the right.

As shown in fig. 2, in one embodiment of the present disclosure, the hand-held assembly 1 is configured to rotate an angle of less than or equal to 90 ° relative to the body 2 to a second position. It will be appreciated that in one embodiment of the present disclosure, when the hand-held assembly 1 is rotated 90 ° relative to the body 2 from the first position to the second position, the direction of extension of the hand-held assembly 1 will be exactly perpendicular to the thickness direction of the body 2, thereby minimizing the length of the hand-held assembly 1 in the thickness direction of the body 2. In yet another embodiment of the present disclosure, the hand-held assembly 1 may also be configured to rotate an angle of less than 90 ° relative to the body 2 to the second position, so long as it is ensured that the length of the handle assembly in the thickness direction of the body 2 does not exceed the thickness of the body 2 when in the second position.

Further, in one embodiment of the present disclosure, the body 2 includes a body and a functional component provided at a front side of the body; in the first position, the hand-held assembly 1 is at least configured to extend in the direction of the front side of the machine body beyond the end face of the functional assembly; in the second position, the hand-held assembly 1 is configured to rotate to a position that does not protrude beyond the front end face of the functional assembly.

Like this, because handheld subassembly 1 is located the first position, can extend to the terminal surface that surpasses the functional module to the front side direction of organism, can guarantee that handheld subassembly 1's length is great to the convenience of customers grips. Since the front end surface of the functional module is not exceeded when the hand-held module 1 is in the second position, it is ensured that the hand-held module 1 does not hinder the cleaning device from entering into a low space.

In particular, as shown in fig. 1 to 3, in one embodiment of the present disclosure, the hand-held assembly 1 further comprises a connection portion 12 connected to the grip structure 11, the connection portion 12 being configured to be disposed coaxially with the body 2 and configured to rotate relative to the body 2; an engagement mechanism is provided between the connection portion 12 and the body 2, the engagement mechanism being configured to hold the connection portion 12 in the first position or the second position.

Because the connecting portion 12 of the handheld component 1 is coaxially arranged with the machine body 2, the rotation axis of the handheld component 1 coincides with the axis of the machine body 2, and the handheld component 1 can rotate along the axis of the machine body 2, so that the movement range of the handheld component 1 during rotation can be effectively reduced, and the handheld component 1 can be conveniently rotated by a user. Through setting up the block mechanism, can keep handheld subassembly 1 in first position or second position, avoid the user to use handheld subassembly 1 at the clean in-process of cleaning equipment of this disclosure to rotate for fuselage 2 at will, influence user normal use.

Wherein, as shown in fig. 1, in one embodiment of the present disclosure, an extension tube 21 may be provided on the body 2, and the connection portion 12 is engaged with the extension tube 21. In yet another embodiment of the present disclosure, the connection portion 12 may also be extended to directly mate with the body of the fuselage 2, without limitation.

The engagement mechanism may take a variety of forms. As shown in fig. 2 to 4, in one embodiment of the present disclosure, the engagement mechanism includes a limit portion 22 and a mating portion, the limit portion 22 is disposed on the body 2, and the mating portion is disposed on the connection portion 12; the limit portion 22 is configured to be located in the mating portion when located in the first position or the second position; the limit portion 22 is configured to be separated from the mating portion when the connecting portion 12 rotates relative to the body 2.

By providing the limiting portion 22 and the mating portion, the user maintains the hand-held assembly 1 in the first position or the second position during cleaning by the cleaning apparatus of the present disclosure; when the user needs to adjust the position of the handheld assembly 1, the limiting part 22 can be separated from the matching part when the connecting part 12 rotates relative to the machine body 2, so that the handheld assembly 1 can be switched between the first position or the second position.

Specifically, as shown in fig. 2 and 3, in one embodiment of the present disclosure, the mating portion is a limiting groove 121, a flange 122 is disposed on a rotating surface of the connecting portion 12 for mating with the machine body 2, and the limiting groove 121 is defined between the two flanges 122. When the hand-held assembly 1 is located at the first position or the second position, the limiting portion 22 can be clamped between the two flanges 122, so that the hand-held assembly 1 is kept at the first position or the second position.

To enable the retainer 22 to move out of the retainer groove 121 or into the retainer groove 121 when the connecting portion 12 is rotated relative to the body 2, in one embodiment of the present disclosure, the retainer 22 is configured to deform the crush flange 122 to move out of or into the retainer groove 121. By pressing the flange 122, the flange 122 is deformed and then retracted from the rotation surface, so that the stopper 22 can pass through the flange 122. It can be seen that the flange 122 can limit the limit portion 22 in the limit groove 121 by its own elastic force when the connection portion 12 is not rotated; when the connecting portion 12 rotates relative to the machine body 2, the limiting portion 22 can press the flange 122 to deform and leave from the limiting groove 121 or enter the limiting groove 121.

Further, the location of the deformation portion 123 may be selected in various ways. As shown in fig. 1, in one embodiment of the present disclosure, deformation parts 123 are provided on the connection parts 12 and correspond to the flanges 122 one by one, the flanges 122 are provided on the corresponding deformation parts 123, and the stopper 22 is provided on the body 2 and is configured to be deformed by pressing the deformation parts 123 to be separated from or enter the stopper groove 121. Thus, during rotation of the limiting portion 22, the flanges 122 are sequentially pressed to deform so as to be separated from or enter the limiting groove 121.

In yet another embodiment of the present disclosure, the deformation portion 123 is disposed on the connection portion 12, and the flange 122 and the limit groove 121 surrounded by the flange 122 are disposed on the deformation portion 123, and the limit portion 22 is disposed on the body 2 and is configured to be deformed by pressing the deformation portion 123 to be separated from or enter the limit groove 121. In this way, after any flange 122 is pressed during the rotation of the limiting portion 22, the corresponding limiting groove 121 and the other flange 122 surrounding the limiting groove 121 are driven to move, until the limiting portion 22 is completely separated from or enters the limiting groove 121, the flange 122 and the limiting groove 121 can not return to the original positions.

In another embodiment of the present disclosure, a deformation portion 123 may be further disposed on the rotation surface of the body 2, the limit portion 22 is disposed on the deformation portion 123, and the limit groove 121 surrounded by the flange 122 is disposed on the rotation surface of the body 2 or the connection portion 12; the deformation portion 123 is configured to deform when subjected to a pressing force so that the stopper portion 22 is disengaged from or enters the stopper groove 121. In this way, in the rotation process of the limiting portion 22, after the limiting portion 22 is pressed against the flange 122, the deformation portion 123 deforms itself, so as to drive the limiting portion 22 to move, and thus the limiting portion 22 is separated from or enters the limiting groove 121.

As shown in fig. 1 to 3, in one embodiment of the present disclosure, the deformation portion 123 may be formed by providing a hollow 124 having a non-closed structure on the rotation surface of the connection portion 12 or the body 2. That is, only one end of the deformation portion 123 is connected with the connecting portion 12 or the machine body 2, and other portions are not contacted with the connecting portion 12 or the machine body 2, so that the deformation portion 123 can generate larger deformation under the extrusion force, and the limit portion 22 is easier to separate from or enter the limit groove 121.

In one embodiment of the present disclosure, as shown in fig. 2, a rotating region 125 and a non-rotating region 126 are provided in the circumferential direction of the connection portion 12, wherein the outer diameter of the non-rotating region 126 is larger than that of the rotating region 125, and a step 127 is formed at a position where the two are connected; in the second position, the limit portion 22 is configured to rotate until the step 127 engages and serves as a rotational stop for the limit portion 22.

Like this, spacing portion 22 can rotate in the rotation district 125, and its rotation dead point is the step 127 between rotation district 125 and the non-rotation district 126 promptly, and the position of handle subassembly when spacing portion 22 reached step 127 is regarded as the second position, and when the user need rotate the handle subassembly to the second position, only need rotate the handle subassembly along predetermineeing the direction to unable rotation, can reach the purpose, need not the user and aim at the second position alone.

Similarly, as shown in fig. 2 and 3, in one embodiment of the present disclosure, a deformation portion 123 is provided at a position of the rotation region 125 adjacent to the step 127, and the mating portion is a flange 122 provided on the deformation portion 123; in the second position, the stop 22 is configured to be positioned in the stop slot 121 defined by the flange 122 and the step 127. When the connecting part 12 does not rotate, the flange 122 can limit the limit part 22 in the limit groove 121 surrounded by the flange 122 and the step 127 through self elasticity; when the connecting portion 12 rotates relative to the body 2, the limiting portion 22 can press the flange 122 to deform to leave from the limiting groove 121 or enter into the limiting groove 121, so that the handheld assembly 1 can leave the second position or enter into the second position.

While in other embodiments of the present disclosure, the limit portion 22 may be provided on the connection portion 12, and the mating portion is provided on the body 2; the flange 122 may also be provided on the rotation surface of the body 2 for cooperation with the connection portion 12; the deformation part 123 connected with the flange 122 is arranged on the machine body 2, and the limit part 22 is arranged on the rotating surface of the connecting part 12; or, the deformation part 123 connected with the limit part 22 is arranged on the connecting part 12, and the matching part is arranged on the rotating surface of the machine body 2; and a rotating region 125 and a non-rotating region 126 are provided in the circumferential direction of the body 2. The specific structure can be adjusted according to the need, and the specific principle is the same as that of the structure, and is not repeated here.

Thus, when the hand-held assembly 1 is in the first position, the hand-held assembly 1 extends in a direction parallel to the thickness direction of the body 2, and the length in the thickness direction of the body 2 is relatively large, and is usually larger than the thickness of the body 2 itself; when the hand-held assembly 1 rotates to the second position, the length of the hand-held assembly 1 in the thickness direction of the machine body 2 does not exceed the thickness of the machine body 2, so that the hand-held assembly 1 does not obstruct the cleaning device from entering the short space, and a user can extend the cleaning device into the short space such as the bed bottom and the sofa bottom, thereby cleaning the working surface in the short space.

In the cleaning device of the present disclosure, the hand-held assembly 1 is rotatable between a first position and a second position, and the user can adjust the position of the hand-held assembly 1 as desired. During normal cleaning, the user can place the hand-held assembly 1 in the first position, thereby facilitating gripping of the handle assembly; when the low space such as the bed bottom and the sofa bottom needs to be cleaned, the user can rotate the handheld assembly 1 to the second position, and then the cleaning equipment stretches into the low space such as the bed bottom and the sofa bottom, so that the working surface in the low space is cleaned.

It can be seen that the cleaning device of the present disclosure can extend into a low space such as a bed bottom and a sofa bottom, and clean a working surface in the low space, thereby effectively improving the use experience of a user.

The foregoing description of the embodiments of the present disclosure has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the various embodiments described.
