Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of cleaning equipment, in particular to a cleaning equipment. BACKGROUND

[0002] With the development of household cleaning equipment and the increasing demand of household users for cleaning effect, among them, the scrubber is favored by consumers due to its high efficiency, convenience, environmental protection and dry-wet dual use. For a handheld scrubber, when cleaning low space (such as the bottom of a sofa, the bottom of a bed, etc.), the scrubber lies flat on the ground so that the scrubber can extend into the low space to achieve cleaning.

[0003] Although this can achieve cleaning of low space, the length of the original scrubber handle is generally designed to be suitable for users to control the machine in a non-machine body lying state, and if the machine body lying state is needed, the length and height of the handle are not suitable for users to hold, resulting in that the user needs to squat or bend, which is not suitable for the user's back and the use experience is poor. UTILITY MODEL CONTENT

[0004] The present disclosure provides a cleaning equipment to solve the problems in the prior art.

[0005] According to a first aspect of the present disclosure, a cleaning equipment is provided, comprising a brush assembly, a machine body and a handle assembly, the brush assembly being rotationally connected to the machine body; the handle assembly comprising a connecting rod connected to the machine body, and a handle section connected to the connecting rod:

[0006] The connecting rod comprises a first bending section and a second bending section which are pivotally connected, and the handle section is provided with an extension section which can slide in the inner cavity of the second bending section; the extension section has a storage state of being retracted into the inner cavity of the second bending section, and an extension state of sliding out relative to the second bending section;

[0007] In the storage state, the extension section is configured to lock and fix the first bending section and the second bending section to maintain a straight state;

[0008] In the extension state, the extension section is configured to slide and unlock the first bending section and the second bending section, so that the first bending section and the second bending section can pivot relative to each other.

[0010] The connecting rod comprises a pivotally connected first bent segment and a second bent segment; the handle segment comprises a movable member arranged in the inner cavity of the second bent segment and slidable along the inner cavity; the movable member has an unlocked position in the inner cavity of the second bent segment and a locked position at least partially embedded in the first bent segment;

[0011] When in the locked position, the movable member is configured to lock and fix the first bent segment and the second bent segment to maintain a straight state;

[0012] When in the unlocked position, the movable member is configured to slide and unlock the first bent segment and the second bent segment to allow the first bent segment and the second bent segment to pivot relative to each other.

[0013] According to a third aspect of the present disclosure, a cleaning device is also provided, comprising a floor brush assembly, a main body, and a handle assembly, the floor brush assembly being pivotally connected to the main body; the handle assembly comprising a connecting rod connected to the main body, and a handle segment connected to the connecting rod:

[0014] The connecting rod comprises a pivotally connected first bent segment and a second bent segment; the handle segment comprises a movable member arranged in the inner cavity of the second bent segment and slidable along the inner cavity, and the handle segment and the second bent segment are provided with interlocking structures for mutual locking;

[0041] In the present text, "first", "second" and the like are used only to distinguish from each other, and do not represent importance and order, and the premise of each other.

[0042] In the present text, "equal", "same" and the like are not strictly limited in the mathematical and / or geometric sense, but also include the error allowed by the person skilled in the art in manufacturing or using.

[0043] Reference Figure 1 and Figure 2 The present disclosure provides a cleaning device, which can be a handheld cleaning device such as a handheld washing machine, a handheld wet vacuum cleaner, a handheld scrubber, and the like known to those skilled in the art. The present embodiment takes the cleaning device as a handheld scrubber as an example. As shown in Figure 1 , the cleaning device comprises a brush assembly 300, a body 200, and a handle assembly 100, wherein the brush assembly 300 is configured to clean a work surface. Specifically, the brush assembly 300 is pivotally connected to the body 200, and when the cleaning device is parked on the work surface or is working on the work surface, the brush assembly 300 is in contact with the work surface.

[0044] Further, the handle assembly 100 is arranged above the body 200, and comprises a connecting rod 1 connected to the body 200, and a handle section 2 connected to the connecting rod 1. After the cleaning device is turned on, the user can hold the handle section 2 to control it, for example, can exert force to tilt the body 200 and push and pull back and forth, so that the brush assembly 300 moves on the work surface to achieve the purpose of cleaning the dirt on the work surface; when the user holds the handle section 2 of the handle assembly 100, and then drives the body 200 to stand up through the connecting rod 1, the cleaning device stops working.

[0045] The connecting rod 1 comprises a first bending section 11 and a second bending section 12 which are pivotally connected, and the handle section 2 is provided with an extension section 3 which can slide in the inner cavity of the second bending section 12. As Figure 4 , Figure 7 and Figure 13As shown, the second bending section 12 is a hollow tubular structure, and the diameter of the telescopic section 3 should be smaller than the inner diameter of the second bending section 12, so that the telescopic structure can be achieved. It can be understood that when the telescopic section 3 is in a freely slidable state, the user can hold the handle section 2 and drive the telescopic section 3 to slide in the inner cavity of the second bending section 12, thereby changing the total length of the connecting rod 1. Specifically, the telescopic section 3 has a storage state of being retracted into the inner cavity of the second bending section 12, and an extended state of being extended out relative to the second bending section 12.

[0046] In the storage state, the telescopic section 3 is configured to lock and fix the first bending section 11 and the second bending section 12 to maintain a straight state. At this time, the length of the connecting rod 1 is the shortest, and the first bending section 11 and the second bending section 12 are in a relatively straight state and cannot be pivoted relative to each other. A user in a standing position can easily hold the handle section 2 to push and pull the cleaning device for cleaning. It should be noted that in most cleaning scenarios, such as cleaning an open work surface, e.g., a floor, a carpet, etc., the telescopic section 3 can be kept in the storage state, so that the connecting rod 1 is kept in the shortest length, and thus the handle section 2 at the top end thereof can be at a height suitable for the user to hold.

[0047] In the extended state, the telescopic section 3 is configured to slide and unlock the first bending section 11 and the second bending section 12, so that the first bending section 11 and the second bending section 12 can be pivoted relative to each other. At this time, the connecting rod 1 has a longer total length, and when the telescopic section 3 moves to the limit position away from the first bending section 11, the handle assembly 100 extends to the longest. Referring to Figure 4 and Figure 7 After the telescopic section 3 is extended, the first bending section 11 and the second bending section 12 can be pivoted relative to each other from a relatively straight state as shown in Figure 4 to an angled state as shown in Figure 7 , for example, can be pivoted to a right angle. As shown in Figure 2 , the first bending section 11 drives the body 200 to pivot relative to the second bending section 12, so that the body 200 can lie flat on the work surface, thereby facilitating the cleaning device to extend into low areas (such as under a bed, under a sofa, etc.) for cleaning.

[0048] The present disclosure realizes the organic combination of the telescopic function and the rotating function of the connecting rod 1. Specifically, in the storage state, the telescopic section 3 can lock and fix the first bending section 11 and the second bending section 12 to avoid relative rotation, and in the extended state, the first bending section 11 and the second bending section 12 can be unlocked to be able to relatively pivot. In the general cleaning scene, the telescopic section 3 can be kept in the storage state, at which time the length of the connecting rod 1 is relatively short and cannot be bent, thereby facilitating the user to hold and operate. When it is necessary to clean the low scene, the telescopic section 3 can be controlled to slide to the extended state, and the first bending section 11 and the second bending section 12 relatively pivot, thereby enabling the body 200 to lie flat on the working surface to clean, thereby improving the cleaning effect of the low space. At the same time, since the total length of the connecting rod 1 is increased, the user does not need to squat or bend to complete the cleaning work, thereby improving the user experience and reducing the damage to the user's back.

[0049] In one embodiment of the present disclosure, referring to Figure 3 and Figure 8 , the end of the first bending section 11 is provided with a connecting portion 4 for connecting with the body 200, and the connecting portion 4 is provided with a roller 5. In the extended state, the first bending section 11 can pivot relative to the second bending section 12 to make the roller 5 cooperate with the working surface. The connecting portion 4 at the end of the first bending section 11 can be fixed with the body 200 by various ways such as insertion, clamping, screwing, etc., so that the body 200 can move with the first bending section 11. When the telescopic section 3 is in the extended state, the first bending section 11 can drive the body 200 to pivot relative to the second bending section 12, thereby enabling the body 200 to lie flat to clean the low area. At this time, as shown in Figure 2 , the roller 5 is in a position cooperating with the working surface, i.e., it can be used as an auxiliary support wheel to rollingly contact with the working surface, thereby enabling the user to more labor-savingly drag the cleaning equipment back and forth during the cleaning of the low area. At the same time, the arrangement of the roller 5 on the handle assembly 100 also avoids the need to add the roller 5 on the body 200, ensures the integrity of the internal mechanism of the body 200, and avoids the potential dirt entering the internal part of the body 200 through the roller 5 structure.

[0050] In one embodiment of the present disclosure, the telescopic section 3 is provided with a first interlocking part at the end thereof adjacent to the first bending section 11, and the first bending section 11 is provided with a second interlocking part; in the storage state, the first interlocking part cooperates with the second interlocking part to lock and fix the first bending section 11 and the second bending section 12. The main purpose of the locking and fixing is to ensure that the first bending section 11 and the second bending section 12 cannot pivot relative to each other, so that the connecting rod 1 can maintain its rigidity in the general cleaning scenario of cleaning the open area; on the other hand, it is also necessary to ensure that the first bending section 11 and the second bending section 12 are straight, so that the user can more easily manually control the walking path of the cleaning device. The first interlocking part and the second interlocking part can adopt any locking structure known to those skilled in the art, and the present disclosure does not make specific limitations thereon, and a specific locking structure is provided below as an example.

[0051] In one specific embodiment of the present disclosure, with reference to Figure 5 , Figure 6 and Figure 11 , the first interlocking part is a protruding part 31 provided at the end of the telescopic section 3, and the second interlocking part is a recessed part 111 provided at the top of the first bending section 11; in the storage state, the protruding part 31 is configured to extend into the recessed part 111. The protruding part 31 is configured to extend along the axis direction of the telescopic section 3, and it can be understood that the extension direction of the telescopic section 3 is basically the same as that of the second bending section 12, so the protruding part 31 basically extends along the axis direction of the second bending section 12. The recessed part 111 extends along the axis direction of the first bending section 11, and only when the first bending section 11 and the second bending section 12 are in a relatively straight state, the protruding part 31 can extend into the recessed part 111, thereby forming an interlocking structure. After the interlocking structure is formed, the first bending section 11 cannot pivot relative to the second bending section 12, and only after the protruding part 31 is moved upward to be out of the recessed part 111 by the telescopic section 3, the unlocking in the rotation direction can be realized, so that the first bending section 11 and the second bending section 12 can pivot relative to each other.

[0052] Further, as Figure 6As shown, the inner cavity bottom of the second bending section 12 is provided with a slot channel 121 through which the protrusion 31 passes. When the telescopic section 3 drives the protrusion 31 to move towards the first bending section 11, the protrusion 31 will first pass through the slot channel 121 before being inserted into the groove portion 111, and the slot channel 121 extends along the axis direction of the second bending section 12. It should be noted that since the telescopic section 3 is movably sleeved in the inner cavity of the second bending section 12, the axis directions of the two may deviate slightly during movement, which may cause the protrusion 31 to be difficult to quickly and accurately align with the groove portion 111. Therefore, the disclosure is provided with the slot channel 121 at the inner cavity bottom of the second bending section 12, so that the protrusion 31 can be guided and positioned in advance, ensuring that the protrusion 31 extends along the axis direction of the second bending section 12. When the first bending section 11 is pivoted to be relatively straight with the second bending section 12, the protrusion 31 can be smoothly, quickly and accurately inserted into the groove portion 111 for locking.

[0053] In one specific embodiment of the disclosure, with reference to Figure 6 、 Figure 8 、 Figure 11 and Figure 14 , one side inner wall of the slot channel 121 is configured to extend downward to form a limiting portion 122, and the limiting portion 122 is configured to form a stepped groove 123 with part of the bottom surface of the second bending section 12; in the storage state, the limiting portion 122 at least partially extends into the groove portion 111 and is located between the protrusion 31 and the inner wall surface of the groove portion 111, and the top end portion of the first bending section 11 is embedded in the stepped groove 123. With reference to the view direction of Figure 6 and Figure 8 , when the first bending section 11 can be rotated relative to the second bending section 12, it can only be rotated in the clockwise direction under the blocking action of the limiting portion 122, thereby driving the body 200 to be rotated in the clockwise direction to the lying state; and in the process of rotating the first bending section 11 back to the original position, when it is rotated in the counterclockwise direction to the position where part of the top end is embedded in the stepped groove 123, that is, the inner wall of part of the top end abuts against the side wall of the limiting portion 122, the first bending section 11 is in a straight state with the second bending section 12. It can be seen that by providing the limiting portion 122, on the one hand, the rotating direction of the first bending section 11 relative to the second bending section 12 can be limited, and on the other hand, it is also helpful to reset the connecting rod 1 to a straight state, so that the user can more conveniently rotate the connecting rod 1, and does not need to carefully adjust the rotating angle for alignment, but only needs to rotate to the limit position where the rotation cannot continue to achieve alignment.

[0054] In one embodiment of the disclosure, with reference to Figure 3 、 Figure 6 and Figure 8The hinge joint of the first bending section 11 and the second bending section 12 is provided with a pivot shaft 13, and the first bending section 11 can rotate relative to the second bending section 12 with the pivot shaft 13 as the axis. The pivot shaft 13 is provided with a protrusion 131 protruding in the radial direction, and the first bending section 11 is provided with an arc-shaped limiting groove 112 matched with the protrusion 131, which can be used to limit the maximum rotation angle of the protrusion 131. For example, the arc of the arc-shaped limiting groove 112 can be set to π / 2, that is, the central angle is 90°, so that the maximum rotation angle of the protrusion 131 in the arc-shaped limiting groove 112 is 90°, that is, the maximum rotation angle of the first bending section 11 relative to the second bending section 12 is 90°.

[0055] In one specific embodiment of the present disclosure, referring to Figure 9 and Figure 11 In the storage state, the projection of the arc-shaped limiting groove 112 and the projection of the protrusion 31 at least partially overlap in the axial direction of the first bending section 11. As described above, the arc-shaped limiting groove 112 is used to limit the rotation angle of the pivot shaft 13, and the protrusion 31 is the core component of the locking structure. In the storage state, the projections of the two overlap, which makes the limiting function of the arc-shaped limiting groove 112 and the locking function of the protrusion 31 cooperate with each other. At the same time, the layout of each structural component is more reasonable, the structural space is reduced, and the handle assembly in the storage state has a more compact structure.

[0056] Further, in the storage state, the axis of the pivot shaft 13 is located within the projection range of the protrusion 31 in the axial direction of the first bending section 11. In this way, the axis of the mutual rotation of the first bending section 11 and the second bending section 12 is located in a substantially central position. In the storage state, the protrusion 31 is inserted into the groove portion 111, and the axis of the pivot shaft 13 is close to the axis of the locking structure, thereby reducing the torque generated by the first bending section 11 and / or the second bending section 12 due to external force, thereby improving the torsional strength after locking and preventing accidental unlocking. In addition, it can also keep the force uniform during folding or unfolding, thereby avoiding wear or deformation caused by eccentricity.

[0057] In one embodiment of the present disclosure, referring to Figure 3 , Figure 5 , Figure 10 and Figure 13 The second bending section 12 is rotatably connected with a release button 6, and the release button 6 is provided with a locking portion 61 close to one end of the handle section 2 and a pressing portion 62 configured to drive the locking portion 61 to move. As shown in Figure 3 , the bottom of the handle section 2 is provided with a matching portion 21 matched with the locking portion 61, and Figure 10As shown, in the storage state, the locking portion 61 is locked with the matching portion 21 to fix the telescopic section 3 in the inner cavity of the second bending section 12. In the storage state, the telescopic section 3 can be entirely retracted into the inner cavity of the second bending section 12, so that the top end of the second bending section 12 can be directly opposite to the bottom of the handle section 2, and the locking portion 61 at the upper portion of the second bending section 12 can be clamped with the matching portion 21 at the bottom of the handle section 2, so as to lock the telescopic section 3 in the inner cavity of the second bending section 12. In the unlocked state, the telescopic section 3 cannot be extended from the inner cavity of the second bending section 12, thereby ensuring that the protruding portion 31 can be stably inserted into the groove portion 111 to prevent accidental unlocking.

[0058] The release button 6 can be rotatably connected to the second bending section 12 through a rotating shaft 63. The rotating shaft 63 can be arranged at the middle portion of the release button 6, so that the release button 6 forms a lever-like structure. When the user applies force to the pressing portion 62, the locking portion 61 can be tilted away from the second bending section 12 under the action of the lever principle, so that the locking portion 61 is separated from the matching portion 21. At this time, the user can pull out the telescopic section 3, so as to unlock the first bending section 11 and the second bending section 12.

[0059] In one specific embodiment of the present disclosure, referring to Figure 3 , Figure 5 and Figure 13 , in the extended state, the top end of the locking portion 61 at least partially protrudes from the top of the second bending section 12 and is suspended along the axial direction of the second bending section 12. A guide inclined surface can be arranged at the upper end of the locking portion 61. When it is needed to change the telescopic section 3 from the extended state to the storage state, the user needs to apply force to the handle section 2, so as to retract the telescopic section 3 into the inner cavity of the second bending section 12. When the matching portion 21 is in contact with the locking portion 61 after retraction, the matching portion 21 can slide along the guide inclined surface, so that the locking portion 61 suspended at the top of the second bending section 12 is deformed until the matching portion 21 moves to the position matched with the locking portion 61. The locking portion 61 is reset, so as to lock the telescopic section 3 in the inner cavity of the second bending section 12.

[0060] It should be noted that, in addition to the clamping and locking form described above, the locking portion 61 and the matching portion 21 can also adopt other locking forms, such as magnetic attraction, bolt, hook, etc., which are not limited in the present disclosure.

[0061] In one embodiment of the present disclosure, referring to Figure 5 , Figure 12 and Figure 13The elastic movable lug 7 is arranged on the telescopic section 3, specifically, the elastic movable lug 7 can be arranged on the telescopic section 3 through elastic means, or the elastic movable lug 7 can be directly made of elastic material, so that it has certain elasticity. The positioning part 124 for cooperating with the elastic movable lug 7 is arranged on the second bending section 12. In the extended state, the elastic movable lug 7 is extended to cooperate with the positioning part 124 under the action of elastic force, so as to fix the telescopic section 3.

[0062] In one specific embodiment of the present disclosure, as shown in Figure 12 The positioning part 124 can be a hole opened on the second bending section 12, and a through hole 32 is also opened on the telescopic section 3; during the movement of the elastic movable lug 7 in the inner cavity of the second bending section 12 along with the telescopic section 3, the elastic movable lug 7 is pre-pressed on the inner wall of the second bending section 12 through elastic means, until it moves to the extended state, the cylindrical flange on the end face of the elastic movable lug 7 can simultaneously penetrate the through hole 32 and the positioning part 124, so as to fix the telescopic section 3 and the second bending section 12 together. The telescopic section 3 can be kept in the extended state under the fixing action of the elastic movable lug 7, so as to avoid the length of the connecting rod 1 changing at any time when the user uses the cleaning device to clean the low area, which causes the cleaning device to be unable to operate normally.

[0063] The elastic movable lug 7 is configured to move away from the positioning part 124 under the action of external force, so as to release the telescopic section 3. Specifically, the positioning part 124 can be arranged at a position opposite to the pressing part 62, in the extended state, the pressing part 62 pushes the elastic movable lug 7 away from the positioning part 124 under the action of external force, so as to release the telescopic section 3. As shown in Figure 13 The pressing part 62 is provided with a top abutting column 621 on the side facing the elastic movable lug 7, when the elastic movable lug 7 moves to the position cooperating with the positioning part 124, the top abutting column 621 cooperates with the elastic movable lug 7; when the user needs to release the fixed state of the telescopic section 3, the user only needs to press the pressing part 62, the top abutting column 621 can push the elastic movable lug 7 to move away from the positioning part 124, and the telescopic section 3 losing the fixed state will drive the elastic movable lug 7 to fall back to the storage position.

[0064] According to the second aspect of the present disclosure, a cleaning device is also provided, which comprises a floor brush assembly 300, a main body 200, and a handle assembly 100. The floor brush assembly 300 is pivotally connected to the main body 200. The handle assembly 100 comprises a connecting rod 1 connected to the main body 200, and a handle section 2 connected to the connecting rod 1. The connecting rod 1 comprises a first bending section 11 and a second bending section 12 which are pivotally connected. The handle section 2 comprises a movable member arranged in the inner cavity of the second bending section 12 and slidable along the inner cavity. The movable member has an unlocked position in the inner cavity of the second bending section 12, and a locked position at least partially embedded in the first bending section 11. When in the locked position, the movable member is configured to lock and fix the first bending section 11 and the second bending section 12 to maintain a straight state.

[0070] Application scenarios

[0071] In the household cleaning scenario, the cleaning device is a handheld scrubber. When the handheld scrubber is used to clean the ground in a relatively open space, the user can hold the handle section 2 to control it, for example, can exert force to tilt the machine body 200 and push and pull back and forth, and the brush assembly 300 moves on the working surface to achieve the purpose of cleaning the dirt on the ground. At this time, the telescopic section 3 can be kept in the storage state, so that the handle section 2 at the top end can be at a height suitable for the user to hold.

[0072] When the user needs to clean the ground under the sofa, the machine body 200 needs to be controlled to lie flat, so that the cleaning device can extend into the low area. Specifically, the user can press the pressing part 62 of the release button 6, the locking part 61 can be tilted away from the second bending section 12, so that the locking part 61 is disengaged from the cooperating part 21, at this time the user can pull out the telescopic section 3, the protruding part 31 is disengaged from the groove part 111, and the first bending section 11 can be pivoted relative to the second bending section 12. The movable lug 7 can move in the inner cavity of the second bending section 12 along with the telescopic section 3, and when it moves to the position cooperating with the positioning part 124, the movable lug 7 can fix the telescopic section 3 in the extended state.

[0073] In the extended state, the first bending section 11 can drive the machine body 200 to pivot relative to the second bending section 12, so that the machine body 200 can lie flat to clean the low area. At this time, the roller 5 is in a position cooperating with the ground, that is, it can be used as an auxiliary support wheel to roll in contact with the ground, so that the user can more easily drag the handheld scrubber back and forth during cleaning of the low area.

[0074] After cleaning the ground under the sofa, the user can first rotate the first bending section 11 and the second bending section 12 to the relatively straight state, and then press the pressing part 62, the top abutting column 621 can drive the movable lug 7 to move away from the positioning part 124, and the telescopic section 3, which loses fixation, drives the movable lug 7 to fall back to the storage position. The protruding part 31 at the bottom of the telescopic section 3 can be inserted into the groove part 111, thereby forming an interlocking structure, so that the first bending section 11 cannot pivot relative to the second bending section 12. At the same time, the locking part 61 is locked with the cooperating part 21 to fix the telescopic section 3 in the inner cavity of the second bending section 12, so as to ensure that the protruding part 31 can be stably inserted into the groove part 111, preventing accidental unlocking.

[0075] Having described above several embodiments of the disclosure, any modifications and variations that fall within the scope of the described embodiments are also contemplated by the inventor(s). As such, the foregoing description is not intended to limit the scope of the disclosure, and it is recognized that modifications are contemplated which can provide one or more benefits and which are within the scope of the disclosure. The disclosure is defined by the appended claims.
