Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a vacuum cleaner with floor wiping function. Background Technology

[0002] Multifunctional vacuum cleaners that combine vacuuming and floor mopping (or wiping) functions are well known in the art. These devices typically have both the nozzle and the mopping module located at the bottom for contact with the floor to be cleaned. The mopping module can use disposable or washable and reusable cleaning cloths (such as wipes, cloths, or sponges).

[0003] In practical use, a common operational challenge lies in cleaning areas that are difficult to reach with a standard flat nozzle, such as corners, edges, or areas near vertical baseboards. In traditional designs, the mopping module is usually fixed to the rear of the nozzle. This configuration often prevents the cleaning cloth from making direct and effective contact with vertical surfaces (such as corners) in confined spaces because the outer casing of the nozzle obstructs the view. Therefore, these areas may not be effectively cleaned by the wiping function, requiring manual touch-ups by the user, which reduces the overall convenience of the product. To improve this issue, existing technologies propose designing the nozzle to flip relative to the mopping module. When direct contact with vertical surfaces such as corners is needed, the nozzle is flipped upwards and backwards, allowing the cleaning cloth to make direct and effective contact with the vertical surface. Therefore, the ease of nozzle flipping directly affects the ease of operation of the vacuum cleaner.

[0004] Furthermore, the cleaning cloth in the mopping module needs to be replaced frequently—whether it's installing a new cloth before use or removing and discarding or washing the soiled cloth after use. In existing designs, the operability of the mopping module for replacing the cleaning cloth is often less than ideal. If the cloth installation / removal mechanism is too cumbersome, or if the mopping module itself is difficult to access, it will also significantly reduce the user experience and the ease of operation of the vacuum cleaner. Summary of the Invention

[0005] To address the aforementioned problems, the purpose of this invention is to provide a vacuum cleaner that can efficiently flip the nozzle and simplify the cleaning cloth removal process, serving both as a vacuum cleaner and a floor cleaner.

[0006] Therefore, the present invention provides a vacuum cleaner with a floor wiping function, the vacuum cleaner comprising: a base configured to selectively hold a cleaning cloth, wherein the cleaning cloth, when held on the base, is in contact with the floor to be cleaned; a clamp disposed on the base and located at a position configured to releasably hold a pair of opposing sides of the cleaning cloth on the base; a push rod assembly including a proximal end and a distal end spaced apart from each other in a vertical direction, the distal end of the push rod assembly being rotatably connected to the base; and a vacuum cleaning system including a nozzle, a dust cup, and a vacuum motor, the nozzle having a suction port; the nozzle being disposed on the base. The cleaning cloth is configured to be releasably held in a vacuuming position, in which the suction nozzle is located on the front side of the base and faces the surface to be cleaned; and a triggering member is movably disposed on the push rod assembly between an initial position, a first position, and a second position; the triggering member is simultaneously drivenly connected to the nozzle and the clamp, such that the nozzle can be released from the vacuuming position in response to the triggering member moving from the initial position to the first position, and that the clamp can release a pair of opposite sides of the cleaning cloth in response to the triggering member moving from the first position to the second position.

[0007] In some embodiments, the triggering element is slidably disposed on the push rod assembly in the vertical direction.

[0008] In some embodiments, the push rod assembly includes a rod, and the triggering component includes a sliding sleeve that is slidably fitted around the rod in a vertical direction.

[0009] In some embodiments, the triggering component further includes a sliding member disposed inside the rod, the triggering member being fixedly disposed with the sliding member.

[0010] In some embodiments, the triggering component further includes: a limiting seat disposed inside the rod; the limiting seat is used to define the extreme position of the sliding member moving upward relative to the rod.

[0011] In some embodiments, a first reset element is provided between the limiting seat and the sliding component.

[0012] In some embodiments, the vacuum cleaner further includes a locking mechanism, which includes a latch member disposed on the base and a locking groove disposed on the nozzle. The latch member is operable between a locked position and a released position. In the locked position, the latch member engages with the locking groove, and the nozzle is locked in the vacuuming position. In the released position, the latch member disengages from the locking groove, and the nozzle is released from the vacuuming position.

[0013] In some embodiments, the clamp includes: a pair of clamping members, the pair of clamping members being movably arranged at the front and rear of the base respectively in a front-rear direction between a clamping position and a releasing position, the movement directions of the pair of clamping members always being opposite; and a latching member being arranged on the movement path of the clamping members located at the front of the base and being able to be pushed from the locked position to the released position by the rearward movement of the clamping members.

[0014] In some embodiments, when the nozzle is in the suction position, there is a gap between the suction port and the clamping member located at the front of the base, the gap having a width dimension measured in the front-rear direction; the width dimension is greater than or equal to a first travel distance of the clamping member located at the front of the base moving from the rear to the front when the latching member is pushed from the locked position to the released position.

[0015] In some embodiments, the width dimension is less than the second travel distance experienced by the clamping member located at the front of the base as it moves from the clamping position to the unclamping position.

[0016] In some embodiments, the latching member is movably disposed on the base between the locked position and the released position in a left-right direction.

[0017] In some embodiments, the vacuum cleaner further includes: a pair of push blocks, each movable in a left-right direction on the base, the pair of push blocks always moving in opposite directions; the pair of push blocks contact the pair of clamping members and are configured to push the pair of clamping members to move in a front-back direction when they move in the left-right direction.

[0018] In some embodiments, a pair of power transmission cables are located between the triggering component and the pair of push blocks.

[0019] In some embodiments, the vacuum cleaner is characterized by further comprising: a second reset element, wherein the triggering component is capable of resetting to the initial position by means of the force generated by the second reset element after the external force is removed.

[0020] In some embodiments, the vacuum cleaner is characterized in that the nozzle includes a pair of rotating connecting arms, the top of the base is provided with a pair of shoulders, the pair of rotating connecting arms are rotatably connected to the pair of shoulders, and one or more third reset elements are provided between the pair of rotating connecting arms and the pair of shoulders.

[0021] Compared with existing technologies, the beneficial effects of this invention are as follows: By setting a trigger component on the push rod assembly, this trigger component can simultaneously link the nozzle lock and the clamp, eliminating the need for separate switches, simplifying the structure, and reducing costs and failure rates. Furthermore, through the continuous movement of this trigger component, the release of the nozzle and the release of the cleaning fluid are intelligently and sequentially controlled, eliminating the need for the user to bend over or use both hands to operate different latches or switches separately. Therefore, the vacuum cleaner of this application can adapt to various cleaning scenarios, allowing users to quickly and seamlessly switch between multiple modes such as pure vacuuming and vacuuming followed by wiping, achieving deep cleaning.

[0023] This application relates to a vacuum cleaner with a floor wiping function, which can simultaneously perform vacuuming and floor wiping. The cleaning cloth can be a disposable sheet or a reusable cloth. During operation, the vacuum cleaner can selectively perform both vacuuming and wiping simultaneously, or perform vacuuming or wiping only; the choice can be made freely based on needs.

[0024] See Figure 1 and Figure 2 This illustration shows an embodiment of a vacuum cleaner 100 according to this application. The vacuum cleaner 100 is configured as a push-stick device, comprising a cleaning head 1 and a push-stick assembly 2. The push-stick assembly 2 has a proximal end 201 and a distal end 202 that are spaced apart from each other in the vertical direction; wherein the distal end 202 is rotatably connected to the cleaning head 1. The cleaning head 1 and the push-stick assembly 2 together constitute a vacuum cleaning system. This vacuum cleaning system includes a nozzle 31, a dust cup 32, and a vacuum motor 33. In this example, the nozzle 31 is located at the cleaning head 1, and the dust cup 32 and the vacuum motor 33 are integrated into a detachable portable vacuum cleaner main module mounted on the push-stick assembly 2; the user can remove the portable vacuum cleaner main module from the push-stick assembly 2 for use as needed.

[0025] The cleaning head 1 includes a base 11 that selectively holds a cleaning cloth 900 that collects dust and debris from the surface to be cleaned. This cleaning cloth 900 is typically a thin, disposable cleaning cloth. Figure 3 As shown, the cleaning cloth 900 has a pair of opposite side portions 901 and a middle portion 902 located between the pair of side portions 901. The middle portion 902 can directly contact the surface to be cleaned, thereby wiping the surface to be cleaned, and the pair of side portions 901 are used to mount the cleaning cloth 900 on the base 11.

[0026] refer to Figure 5 The base 11 has a square structure, comprising a front portion 111, a rear portion 112, a top surface 113, and a bottom surface 114. A clamp 4, consisting of a front clamping member 41 and a rear clamping member 42, is provided at the front portion 111 and rear portion 112. The clamp 4 is configured to releasably hold a pair of opposing side portions 901 of the cleaning cloth 900 on the base 11 during use. Specifically, the front clamping member 41 engages with the front surface 115 of the front portion 111 of the base 11 to hold one side portion 901 of the cleaning cloth 900 at the front portion 111 of the base 11; the front clamping member 42 engages with the rear surface 116 of the rear portion 112 of the base 11 to hold the other side portion 901 of the cleaning cloth 900 at the rear portion 112 of the base 11.

[0027] For better clamping of one side edge of the cleaning cloth 900, several protrusions are arranged between the front clamping member 41 and the front surface 115 of the base 11, and between the front clamping member 42 and the rear surface 116 of the base 11. The size and position of the front clamping member 41 and the rear clamping member 42 can be changed based on the size and shape of the base 11. The cleaning cloth 900 can therefore be releasably mounted to the base 11 using the clamps 4.

[0028] Both the front clamping component 41 and the rear clamping component 42 can clamp the fabric in the front-back direction. Figure 1 Location) and fabric removal location ( Figure 2 , Figure 5 The front clamping member 41 and the rear clamping member 42 are movably arranged at the front 111 and the rear 112 of the base 11. The moving directions of the front clamping member 41 and the rear clamping member 42 are always opposite to achieve the technical effect of "opening" and "closing".

[0029] Combination Figure 6 As shown, the base 11 is composed of an upper housing 101 and a lower housing 102. The upper housing 101 defines the top surface 113 of the base. Springs 43 are respectively provided between the front clamping member 41 and the rear clamping member 42 and the base 11. These springs 43 can generate a reset force after the external force applied to the front clamping member 41 and the rear clamping member 42 is removed, so that the front clamping member 41 and the rear clamping member 42 return to the clamping position.

[0030] During use, the bottom surface 114 of the base 11 adheres to and engages with the middle portion 902 of the cleaning cloth 900 and can contact the surface to be cleaned. In order for the cleaning cloth 900 to better adhere to the surface to be cleaned, the bottom surface 114 can be designed to be made of flexible materials such as foam or rubber with shock-absorbing effect.

[0031] The nozzle 31 has a suction port 311 and a pair of arms 312. The nozzle 31 is rotatably connected to the base 11 via a pair of rearwardly extending arms 312. The nozzle 31 is configured to be releasably held in a vacuuming position on the front side of the base 11 with the suction port 311 facing the floor to be cleaned.

[0032] Specifically, a pair of shoulders 117 are provided on the top surface 113 of the base 11, and a pair of arms 312 are rotatably connected to the shoulders 117. A pair of torsion springs 118 are also provided between the arms 312 and the shoulders 117, which can rotate the nozzle 31 to a non-vacuuming position after it is released from the base 11. A rotary connector 12 (see...) is also mounted on the shoulders 117. Figure 1 The distal end 202 of the push rod assembly 2 is rotatably connected to the base 11 via the rotary connector 12.

[0033] like Figure 1 As shown, when the nozzle 31 is in the vacuuming position, the suction port 311 is substantially parallel to and faces the surface to be cleaned. The suction port 311 is located on the front side of the base 11, and the pair of arms 312 are also approximately parallel to the top surface 113 of the base 11. Figure 2 , 5 As shown, when the nozzle 31 is in the non-vacuuming position, it rotates upward and backward under the action of the torsion spring 118. The suction port 311 is located on the upper part of the base 11, and the pair of arms 312 form an acute angle with the top surface 113 of the base 11. In this non-working position, the nozzle 31 can move backward, and the cleaning cloth 900 of the base 11 can be located at the very front of the entire cleaning head 1, thereby achieving cleaning of the floor without obstruction by the nozzle 31. Similarly, if it is necessary to replace the cleaning cloth 900, the nozzle 31 must also be switched to this non-working position to facilitate the removal and replacement of the cleaning cloth 900.

[0034] like Figure 4 , Figure 5 and Figure 6 As shown, to ensure that the suction nozzle 31 can be stably held in the suction position, the cleaning head 1 is also provided with a locking mechanism 5. This locking mechanism 5 includes: a pair of latching members 51 disposed on the base 11 and distributed left and right, and a pair of locking grooves 52 disposed on a pair of arms 312. The pair of latching members 51 can move synchronously between the locked position and the released position. Figure 4 As shown, in the locked position, each latching component 51 engages with the corresponding locking groove 52, and the suction nozzle 31 is locked in the suction position; as Figure 5As shown, in the release position, each latching member 51 disengages from its corresponding locking groove 52, and the suction nozzle 31 is released from the suction position. In this example, the latching member 51 is movably mounted on the base 11 in the left-right direction between the locked and released positions. Figure 6 As shown, a pair of springs 53 are provided between a pair of latching components 51 and the base 11. After the external force applied to the latching components 51 is removed, the pair of springs 53 can generate a reset force, causing the pair of latching components 51 to return to the locked position.

[0035] See again Figure 1 The flexible suction tube 34 is connected to the rear of the suction port 311 and extends horizontally to the rear, passing upward through the rotating connector 12 to achieve fluid communication with the dust cup 32.

[0036] When the vacuum cleaning system is activated, the dust-laden airflow is drawn in through the suction port 311 of the suction nozzle 31, enters the flexible suction tube 34, moves upward and enters the dust cup 32 for air-dust separation, and then the separated air is discharged after passing through the vacuum motor 33.

[0037] Continue as Figure 6 , Figure 7 As shown, a pair of push blocks 6 are also provided inside the base 11, arranged on the left and right sides, respectively, and are movable in the left and right directions. The moving directions of the pair of push blocks 6 are always opposite. The pair of push blocks 6 simultaneously contact the front clamping member 41 and the rear clamping member 42 and are configured to push the front clamping member 41 and the rear clamping member 42 to move in opposite directions in the front and back directions when the pair of push blocks 6 move in the left and right directions. Specifically, each push block 6 is provided with a pair of inclined surfaces 61 and 62, the front clamping component 41 is provided with a pair of inclined surfaces 411, and the rear clamping component 42 is provided with a pair of inclined surfaces 421. The pair of inclined surfaces 61 on each push block 6 can contact the pair of inclined surfaces 411 on the front clamping component 41, and the pair of inclined surfaces 62 on each push block 6 can contact the pair of inclined surfaces 421 on the rear clamping component 42. When the pair of push blocks 6 move inward (the push block 6 on the left moves to the right, and the push block 6 on the right moves to the left), the front clamping component 41 will move forward, and the rear clamping component 42 will move backward, thereby releasing the front and rear sides of the cleaning cloth 900. Conversely, the movement will clamp the front and rear sides of the cleaning cloth 900.

[0038] refer to Figure 1 and Figure 2The push rod assembly 2 includes a housing 21 and a handle assembly 22 mounted on the upper part of the housing 21. The handle assembly 22 includes a rod 221 and a handle 222. The lower end of the housing 21 forms the distal end 202 of the push rod assembly 2; the handle 222 forms the proximal end 201 of the push rod assembly 2. By operating the handle 222, the user can move the base 11 on the surface to be cleaned, and due to the presence of the rotary connector 12, the push rod assembly 2 can rotate relative to the base 11 about two axes in different directions. Since the technology of the rotary connector 12 is conventional, it will not be described in detail here.

[0039] The push rod assembly 2 is also equipped with a trigger assembly 7, which is configured to be drive-connected to the suction nozzle 3 and the clamp 4 to trigger their actions. Figure 8 As shown, the trigger assembly 7 includes a trigger component 71, a sliding component 72, a limit seat 73, a spring 74, and a pair of power transmission cables 75.

[0040] like Figure 9 , Figure 10 As shown, the triggering component 71 is a sliding sleeve that is movably fitted around the rod 221 between an initial position, a first position, and a second position. The rod 221 has a hollow structure, with the sliding component 72 located inside and fixedly mounted to the triggering component 71; both move synchronously up and down. The limiting seat 73 is also located inside the rod 221 and limits the upward movement of the sliding component 72 to its extreme position (corresponding to the second position of the triggering component 71). A spring 74 is located between the sliding component 72 and the limiting seat 73. The triggering component 71 can return to its initial position after the external force is removed, relying on the force generated by the spring 74.

[0041] A pair of power transmission cables 75 pass through the housing 21, with their ends connected to a sliding component 72 and a pair of push blocks 6, respectively. When the trigger component 71 is slid upward, the sliding component 72 moves accordingly, and the pair of power transmission cables 75 pull the pair of push blocks 6 inward in the left-right direction, thereby pushing the front clamping component 41 of the gripper 4 forward and the rear clamping component 42 backward. When the trigger component 71 is released, the spring 74 will cause the trigger component 71 to return to its initial position, and the sliding component 72 will also move accordingly. The force transmitted by the pair of power transmission cables 75 disappears, and the front clamping component 41 and the rear clamping component 42 move backward to their reset positions.

[0042] refer to Figure 11-16 Based on the fact that the triggering component 71 is simultaneously driven to the nozzle 31 and the clamp 4, the nozzle 31 is able to respond to the triggering component 71 from its initial position ( Figure 11 , Figure 12 Move from current location to first position ( Figure 13 , Figure 14The action of the position) releases the gripper from the suction position located in front of the base 11, and enables the front gripping member 41 and the rear gripping member 42 of the gripper 4 to move from the first position to the second position in response to the trigger member 71. Figure 15 , Figure 16 The action of the cleaning cloth 900 (located in a certain position) releases the cleaning cloth 900 to the opposite pair of side portions 901.

[0043] In this embodiment, a pair of latching components 51 are pushed from the locked position to the released position when the front clamping component 41 moves from back to front. Specifically, the front clamping component 41 is also provided with a pair of inclined surfaces 412, and each latching component 51 is provided with an inclined surface 511; wherein the pair of inclined surfaces 412 on the front clamping component 41 can contact the inclined surfaces 511 on each latching component 51; when the front clamping component 41 moves from back to front, each latching component 51 will move inward (the latching component 51 on the left moves to the right and the latching component 51 on the right moves to the left), thereby disengaging from the locking groove 52, unlocking the locking mechanism 5, and the suction nozzle 31 will be converted to a non-vacuuming position under the action of a pair of torsion springs 118.

[0044] In this embodiment, the triggering component 71 is configured to trigger the front clamping component 41 and the rear clamping component 42 to move forward and backward respectively by a first stroke when moving from the initial position to the first position, and to trigger the front clamping component 41 and the rear clamping component 42 to continue moving forward and backward by a second stroke when moving from the first position to the second position. During the forward movement of the front clamping component 41, a pair of latching components 51 are pushed to move, thereby unlocking the locking mechanism 5, releasing the suction nozzle 31 and allowing it to enter the non-vacuuming position. Therefore, when the triggering component 71 moves from the initial position to the first position, the front clamping component 41 moves before the suction nozzle 31.

[0045] To prevent interference between the suction nozzle 31 and the front clamping member 41 during movement, when the suction nozzle 31 is in the suction position, there is a gap 15 between the suction port 311 of the suction nozzle 3 and the front clamping member 41. This gap 15 has a first width W measured in the front-to-back direction. This width W is greater than or equal to the distance L1 (i.e., the distance of the first stroke) that the front clamping member 41 moves from back to front when the latching member 51 is pushed from the locked position to the released position. This width W is less than the travel distance L0 (i.e., the total travel distance of the first stroke and the second stroke) that the front clamping member 41 travels from the cloth clamping position to the cloth release position.

[0046] When the vacuum cleaner 100 is in operation, the front clamping part 41 and the rear clamping part 42 of the clamping member 4 hold the cleaning cloth 900 to the base 11. The nozzle 31 is in the suction position. The user pushes the cleaning head 1 from back to front. Large dust particles on the floor to be cleaned are first sucked away by the suction port 311 of the nozzle 31, and small dust particles are then removed by the cleaning cloth 900. When the user moves to a vertical surface such as a wall, if the cleaning cloth 900 is needed to wipe the surface directly, the user needs to operate the triggering part 71 to move it from the initial position to the first position. Under the triggering of the triggering part 71, the locking mechanism 5 is unlocked, and the nozzle 31 is released from the suction position and enters the non-vacuum position. At this time, the base 11 can carry the cleaning cloth 900 to the position of contacting the surface to wipe the surface. The user can then release the triggering part 71 to return it to the initial position. When the user needs to use the nozzle 31 again, the user flips the nozzle 31 downward until the locking mechanism 5 locks the nozzle 31 in the suction position again. After use, when the user needs to remove the used dirty cleaning cloth 900, the triggering component 71 is slid to the second position. If the triggering component 71 is initially in the initial position, when the triggering component 71 moves to the first position, the front clamping component 41 and the rear clamping component 41 move forward and backward respectively. The locking mechanism 5 is triggered and unlocked by the front clamping component 41, and the suction nozzle 3 is released from the suction position and enters the non-vacuuming position. When the triggering component 71 moves from the first position to the second position, the front clamping component 41 and the rear clamping component 41 continue to move forward and backward respectively to move away from the front part 111 and the rear part 112 of the base 11. The front clamping component 41 and the rear clamping component 42 move from the cloth clamping position to the cloth removal position, and the pair of opposite side parts 901 of the cleaning cloth 900 will be released. At this time, the cleaning cloth 900 can fall off the base 11 by its own gravity.

[0047] The above embodiments are merely illustrative examples, and those skilled in the art can make equivalent substitutions or improvements within the scope of the claims. Other embodiments, besides the exemplary embodiments shown and described herein, are also covered within the scope of this invention.
