Description

Technical Field

[0001] This application belongs to the field of cleaning device technology, and more specifically, this application relates to a cleaning accessory and cleaning equipment. Background Technology

[0002] In people's daily lives, after prolonged use, fabric items such as sofas, carpets, curtains, and leather chairs will accumulate dust, bacteria, and stubborn stains on their surfaces. Specialized cleaning equipment is now available to clean these surface stains.

[0003] In existing technology, cleaning equipment typically consists of two parts: a main unit and cleaning accessories. The cleaning accessories include a handle and a cleaning head. When cleaning the surface of an object, the user can hold the handle to operate the cleaning head. The cleaning head sprays water or a solution containing detergent onto the dirty surface to dilute or dissolve the stains, and relies on negative pressure to collect the wastewater and stains into the wastewater tank inside the main unit.

[0004] During cleaning, users need to press the cleaning head down to ensure that it remains in contact with the surface being cleaned. At the same time, users also need to push and pull the cleaning head on the surface being cleaned. This means that the user's hand needs to apply force in two directions (vertical downward force and horizontal pushing and pulling force) to the cleaning attachment simultaneously, which can easily cause fatigue. Summary of the Invention

[0005] Embodiments of this application provide a cleaning accessory and cleaning device. When the cleaning head is performing cleaning operations, the auxiliary support can be rotated to a second position for auxiliary support, reducing user fatigue. When cleaning a narrow area, the auxiliary support can be rotated to a first position to avoid interfering with the cleaning head's cleaning operations.

[0006] To achieve the aforementioned technical objectives, the first aspect of this application discloses a cleaning accessory, including a cleaning head, a handle, and an auxiliary support. The cleaning head is attached to one end of the handle. The auxiliary bracket is rotatably connected to the handle. The auxiliary bracket has a first position and a second position on the rotation path. When the auxiliary bracket is in the first position, the distance between the free end of the auxiliary bracket and the handle is less than the distance between the free end of the auxiliary bracket and the handle when the auxiliary bracket is in the second position.

[0007] To achieve the aforementioned technical objectives, a second aspect of this application discloses a cleaning device, including a main unit and the cleaning accessories described in the first aspect. The handle is detachably connected to the main unit. The cleaning head is equipped with a spray nozzle and a wastewater collection port. The handle has independent clean water channels and wastewater channels. The main unit includes a casing, a clean water tank, a wastewater tank, a liquid supply mechanism, and a sludge suction mechanism. The clean water tank is connected to the casing and has a clean water outlet. The clean water outlet communicates with the spray nozzle through a clean water channel. The liquid supply mechanism is located inside the casing and communicates with the clean water tank. The liquid supply mechanism is used to transport the solution in the clean water tank to the spray nozzle. The wastewater tank is connected to the housing, and the sludge suction mechanism is located inside the housing. The wastewater tank has a sludge inlet, which is connected to the wastewater recovery port through the wastewater channel. The sludge suction mechanism is connected to the wastewater tank and is used to pump the wastewater from the surface of the object to be cleaned into the wastewater tank through the wastewater recovery port.

[0008] The beneficial effects of this application are as follows: The cleaning accessories and cleaning equipment of this application allow the auxiliary support to be rotated to a second position for auxiliary support when the cleaning head is performing cleaning operations, reducing user fatigue; when cleaning a narrow area, the auxiliary support can be rotated to a first position to avoid interfering with the cleaning head's cleaning operations.

[0018] The cleaning accessories and cleaning equipment provided in this application will be explained and described in detail below with reference to the accompanying drawings.

[0019] This embodiment specifically discloses a cleaning accessory, such as... Figures 1-5 As shown, the device includes a cleaning head 1, a handle 2, and an auxiliary support 3. The cleaning head 1 is connected to one end of the handle 2, and the other end of the handle 2 is connected to the main unit 200 of the cleaning device. Typically, the angle between the cleaning head 1 and the handle 2 is an obtuse angle to ensure that the cleaning head 1 makes full contact with the surface of the object being cleaned while keeping the user's hand as comfortable as possible.

[0020] The auxiliary support 3 is rotatably connected to the handle 2, and is located on the side of the handle 2, on the same side as the cleaning head 1. The auxiliary support 3 has a first position and a second position along its rotation path, and can reciprocate between the first and second positions. The auxiliary support 3 is in the first position (e.g.,...) Figure 1 When (as shown), the distance between the free end of the auxiliary bracket 3 and the handle 2 is less than that of the auxiliary bracket 3 in the second position (as shown). Figure 2 (As shown) is the distance between the free end of the auxiliary support 3 and the handle 2. When the cleaning head 1 moves across the surface of the object being cleaned, as... Figure 1 As shown, the auxiliary support 3 is in the first position, and the auxiliary support 3 does not contact the surface of the object being cleaned. That is, when the auxiliary support 3 is in the first position, the auxiliary support 3 is in a retracted state and does not affect the movement of the cleaning head 1 on the surface of the object being cleaned. When the cleaning head 1 is idle, the auxiliary support 3 can rotate to the first position to reduce the volume occupied by the cleaning attachment 100. When the cleaning head 1 is cleaning a narrow area, the auxiliary support 3 can also rotate to the first position and be in a retracted state to reduce the volume occupied by the cleaning attachment 100, so that the cleaning attachment 100 can be used at an angle, avoiding the auxiliary support 3 interfering with the cleaning operation of the cleaning head 1. Figure 2As shown, when the cleaning head 1 moves on the surface of the object being cleaned, the auxiliary support 3 is in the second position. The auxiliary support 3 can contact the surface of the object being cleaned to provide support, which can reduce the force applied by the user to the cleaning head 1 and reduce the user's fatigue.

[0021] Optional, such as Figure 2 As shown, when the auxiliary support 3 is in the second position, the ends of the auxiliary support 3 and the cleaning head 1 near the handle 2 are close to each other, while the free end of the auxiliary support 3 and the end of the cleaning head 1 away from the handle 2 are far apart. The auxiliary support 3, handle 2, and cleaning head 1 form a trapezoidal shape. When the cleaning head 1 cleans the object being cleaned, the auxiliary support 3 provides a support force perpendicular to the surface of the object being cleaned. The force applied by the user in this direction is reduced, requiring only a small force to push or pull the cleaning head 1 to make it reciprocate on the surface of the object being cleaned. The auxiliary support 3 is inclined relative to the surface of the object being cleaned, and the support force it provides can be decomposed into a horizontal force and a vertical force, so that the auxiliary support 3 can provide a stable support force when the cleaning head 1 reciprocates on the surface of the object being cleaned. Compared to the auxiliary support 3 being perpendicular to the surface of the object being cleaned, the auxiliary support 3 in this embodiment is inclined relative to the surface of the object being cleaned, resulting in more stable support.

[0022] like Figures 1-5 As shown, the auxiliary support 3 can be trapezoidal. The length of the end of the auxiliary support 3 connected to the handle 2 is less than the length of the free end, which increases the contact area with the surface of the object being cleaned and makes the support more stable.

[0023] In some optional embodiments, to facilitate the connection and rotation of the auxiliary support 3 and the handle 2, such as... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the handle 2 includes a gripping rod 21 and a connector 22. One end of the gripping rod 21 is connected to the cleaning head 1, and the other end is connected to the connector 22. The connector 22 and the gripping rod 21 are set at a preset angle. Preferably, the angle between the connector 22 and the portion of the gripping rod 21 near the cleaning head 1 is equal to or slightly greater than 90°. The connector 22 and the cleaning head 1 are located on the same side of the gripping rod 21. The auxiliary bracket 3 is rotatably connected to the end of the connector 22 away from the gripping rod 21. Rotating shafts 221 can be provided on both sides of the end of the connector 22 away from the gripping rod 21. The rotating shafts 221 are perpendicular to the gripping rod 21. The auxiliary bracket 3 is sleeved on the rotating shafts 221 and can rotate around the rotating shafts 221. Figure 2As shown, when the auxiliary support 3 is in the second position, the angle between the auxiliary support 3 and the part of the grip 21 near the cleaning head 1 is an obtuse angle. In one embodiment, this angle is 110° or more. The specific angle can be set as needed, as long as it ensures that the auxiliary support 3 can contact the surface of the object being cleaned when it is in the second position, and that the end of the cleaning head 1 away from the grip 21 can fully contact the surface of the object being cleaned without affecting the cleaning effect. Figure 1 , Figure 4 and Figure 5 As shown, when the auxiliary support 3 is in the first position, it can be parallel to the gripping rod 21 or at a certain angle. As long as the auxiliary support 3 does not contact the surface of the object being cleaned and cause interference when the cleaning head 1 is cleaning, it is acceptable.

[0024] In some optional embodiments, both the auxiliary support 3 and the rotating shaft 221 can be made of damping material. After the auxiliary support 3 rotates to the first position or the second position under the action of external force, the external force is removed, and the auxiliary support 3 can be stably maintained in the first position or the second position.

[0025] In some optional embodiments, a damping element may be provided between the auxiliary support 3 and the rotating shaft 221. After the auxiliary support 3 rotates to the first position or the second position under the action of an external force, the external force is removed, and the auxiliary support 3 can be stably maintained in the first position or the second position under the action of the damping element.

[0026] In some alternative embodiments, such as Figure 1 and Figure 2 As shown, the cleaning accessory 100 of this application also includes a position locking component 4. The position locking component 4 includes a first locking member 41, a second locking member 42, and a third locking member 43. The first locking member 41 and the second locking member 42 are disposed on the handle 2, and the third locking member 43 is disposed on the auxiliary support 3. The first locking member 41 and the third locking member 43 can be locked to lock the auxiliary support 3 in the first position to prevent the auxiliary support 3 from disengaging from the first position and rotating to the second position during the cleaning process of the cleaning head 1, which would affect the cleaning operation of the cleaning head 1. The second locking member 42 and the third locking member 43 can be locked to lock the auxiliary support 3 in the second position to ensure the stability of the support.

[0027] Specifically, the first locking member 41 is disposed on the surface of the connector 22 near the cleaning head 1, and the second locking member 42 is disposed on the surface of the connector 22 away from the grip bar 21. Figure 1 and Figure 2 As shown, the end of the connector 22 away from the gripping rod 21 can protrude from the rotating shaft 221. The second locking member 42 is disposed on the surface of this end. The end of the auxiliary bracket 3 connected to the rotating shaft 221 is provided with a clearance opening 31. Preferably, the clearance opening 31 is disposed at the center of the end of the auxiliary bracket 3. Figure 2As shown, the third locking member 43 is disposed in the clearance opening 31 of the auxiliary bracket 3.

[0028] Optionally, the third locking member 43 can be either a locking groove or a locking buckle, while the first locking member 41 and the second locking member 42 can both be either a locking groove or a locking buckle. When the third locking member 43 is a locking groove on the auxiliary bracket 3, the first locking member 41 and the second locking member 42 can both be locking buckles on the handle 2. When the third locking member 43 is a locking buckle on the auxiliary bracket 3, the first locking member 41 and the second locking member 42 can both be locking grooves on the handle 2. The locking buckle and the locking groove engage to lock the position. This application achieves position locking through the engagement of the locking buckle and the locking groove, resulting in a more secure lock, especially when the auxiliary bracket 3 is in the second position, where the auxiliary bracket 3 provides stable support.

[0029] The locking buckle can slide relative to the handle 2 or auxiliary support 3 it is located on. A first compression-type elastic element is provided on the sliding path of the locking buckle. One end of the first compression-type elastic element is connected to the locking buckle, and the other end is connected to the handle 2 or auxiliary support 3 where the locking buckle is located. The elastic deformation direction of the first compression-type elastic element is along the sliding direction of the locking buckle. When the locking buckle slides towards the handle 2 or auxiliary support 3 where it is located, the first compression-type elastic element is compressed. The first compression-type elastic element can be a spring or a sheet. Taking the locking of the first locking member 41 and the third locking member 43 as an example, when the locking buckle moves towards the handle 2 or auxiliary support 3 where it is located, the first compression-type elastic element is compressed. After the locking buckle is aligned with the locking groove, the force applied to the locking buckle is released, and the first compression-type elastic element returns to its initial state. The restoring elastic force of the first compression-type elastic element drives the locking buckle to move away from the handle 2 or auxiliary support 3 where it is located and enter the locking groove to achieve locking. When releasing the lock, the locking latch moves towards the handle 2 or auxiliary bracket 3 where it is located. The first compression-type elastic element is compressed, and the auxiliary bracket 3 is rotated, causing the locking latch to disengage from the locking slot. The first compression-type elastic element facilitates user operation and ensures the stability of the lock. A first guide groove 32 can be provided on the handle 2 or auxiliary bracket 3 where the locking latch is located. The first compression-type elastic element is located in the first guide groove 32. The first guide groove 32 is used to limit the compression direction of the first compression-type elastic element and the sliding direction of the locking latch, preventing the first compression-type elastic element from tilting when deformed.

[0030] The end of the locking buckle inserted into the locking slot can be arrow-shaped, consisting of two connected bevels. When the auxiliary bracket 3 rotates, one bevel of the locking buckle first contacts the surface of the auxiliary bracket 3 or handle 2 where the locking slot is located. The bevel acts as a guide, causing the locking buckle to slide away from the locking slot. The first compression elastic element is compressed first, and then enters the locking slot to engage. The first compression elastic element then returns to its initial state. The bevel design allows the locking buckle and locking slot to engage without manual manipulation; the locking buckle enters the locking slot and engages under the interaction force. When removing the locking buckle from the locking slot, the other bevel of the locking buckle also acts as a guide.

[0031] For ease of operation, such as Figure 2 and Figure 3 As shown, the locking buckle is provided with a first handle protrusion 44, which makes it easy for the user to operate the first handle protrusion 44 to drive the locking buckle to slide relative to the handle 2 or auxiliary bracket 3 on which it is located.

[0032] Optionally, the third locking member 43 can be magnetically locked to the first locking member 41, and the third locking member 43 can be magnetically locked to the second locking member 42. The third locking member 43, the first locking member 41, and the second locking member 42 can all be magnetic; the third locking member 43 can be a magnet, while the first locking member 41 and the second locking member 42 are ferrous structures; or the third locking member 43 can be a ferrous structure, while the first locking member 41 and the second locking member 42 are magnets. When the auxiliary support 3 rotates to the first position, the first locking member 41 and the third locking member 43 magnetically lock together, locking the auxiliary support 3 in the first position; when the auxiliary support 3 rotates to the second position, the second locking member 42 and the third locking member 43 magnetically lock together, locking the auxiliary support 3 in the second position. In this embodiment, the auxiliary support 3 can also be locked in the first or second position through magnetic locking.

[0033] In some alternative embodiments, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a stop 23 is also provided on the handle 2. The stop 23 is disposed on the connector 22. The stop 23 is used to prevent the auxiliary support 3 from rotating further away from the first position from the second position. That is, the stop 23 limits the maximum angle of the auxiliary support 3 in the unfolded state, and at the same time further enhances the stability of the auxiliary support 3 in the second position, improving the stable support force. When the auxiliary support 3 rotates to the second position, the surface of the auxiliary support 3 contacts the stop 23, and the stop 23 prevents the auxiliary support 3 from rotating further, so that the auxiliary support 3 stays in the second position.

[0034] In some alternative embodiments, such as Figure 1As shown, the cleaning accessory 100 of this application also includes a counterweight 5, which is detachably connected to the cleaning head 1. The counterweight 5 is located on the side of the cleaning head 1 near the auxiliary support 3. The counterweight 5 is used to increase the downward pressure of the cleaning head 1 on the surface of the object being cleaned, and can completely or partially replace the downward pressure of the user's hand, reducing user fatigue. The counterweight 5 is detachably connected to the cleaning head 1, and its weight can be adjusted as needed, thereby adjusting the downward pressure. When cleaning a horizontal surface, the counterweight 5 increases the downward pressure of the cleaning head 1 on the surface, making it easier for the user and reducing user fatigue. When cleaning a vertical surface, the counterweight 5 can be removed from the cleaning head 1, reducing the burden on the user's hands.

[0035] The counterweight 5 is set on the surface of the cleaning head 1 near the auxiliary support 3. This surface has a large area, which facilitates the installation of the counterweight 5 and does not increase the volume of the cleaning accessory 100.

[0036] The weight of the counterweight 5 can be adjusted by replacing the counterweight 5 with one of different materials, thereby changing the weight of the counterweight 5 by changing its density; the counterweight 5 can also include a housing 51 and a medium filled inside the housing 51, thereby changing the weight of the counterweight 5 by changing the type of medium filled inside the housing 51 or changing the amount of medium inside the housing 51.

[0037] In one embodiment, the counterweight 5 includes a housing 51 and a counterweight liquid within the housing 51, such as... Figure 6 As shown, the housing 51 has an inlet / outlet port 511. The weight of the counterweight 5 can be adjusted by changing the type or volume of the counterweight liquid inside the housing 51. The housing 51 has an internal cavity for holding the counterweight liquid. The counterweight liquid is contained within this cavity, and the inlet / outlet port 511 communicates with the cavity for injecting or discharging the counterweight liquid. Figure 7 As shown, a sealing cap 56 is provided at the inlet / outlet 511. The sealing cap 56 can be detachably or rotatably connected to the housing 51 to open the inlet / outlet 511. The detachable connection can be a snap-fit ​​or a sealing connection. The weight of the counterweight 5 can be adjusted by adjusting the type or volume of the counterweight liquid inside the housing 51, thereby adjusting the downward pressure. The adjustment method is simple and flexible. Moreover, the position of the counterweight liquid inside the housing 51 changes according to the angle of the cleaning head 1, and the center of gravity can change with the angle of the cleaning head 1 to provide a constant downward pressure. Preferably, the counterweight liquid is water, which is readily available and inexpensive.

[0038] Optionally, one end of the sealing cap 56 is rotatably connected to the counterweight 5, for example, via a hinge or crease. The end of the sealing cap 56 opposite to the rotatably connected part of the counterweight 5 is locked by a locking assembly. The locking assembly may include two magnetically attracted elements. When the sealing cap 56 is placed over the inlet / outlet 511, the two magnetically attracted elements lock the sealing cap 56 at the inlet / outlet 511. Both magnetically attracted elements may be magnetic, or one may be a magnet and the other may be an iron structure. The locking assembly may also include two locking elements that engage. In this embodiment, the locking assembly may include a sealing protrusion (not shown in the figure) provided on the surface of the sealing cap 56 and a sealing groove or sealing hole 512 (e.g., on the housing 51) provided on the housing 51. Figure 6 As shown), the sealing protrusion is inserted into the sealing groove or sealing hole 512 on the counterweight 5, locking the sealing cover 56 at the inlet / outlet 511 to achieve the sealing of the inlet / outlet 511.

[0039] Preferably, the counterweight 5 can be trapezoidal, which on the one hand matches the shape of the cleaning head 1, and the housing 51 of the counterweight 5 can accommodate more counterweight medium; on the other hand, it makes the center of gravity of the counterweight 5 lower when cleaning the surface of the object being cleaned, and the downward pressure is more stable.

[0040] The counterweight 5 can be directly connected to the surface of the cleaning head 1, such as by magnetic connection; the surface of the cleaning head 1 can also have a groove 11, and the counterweight 5 can be detachably set in the groove 11. The connection between the counterweight 5 and the cleaning head 1 can be by magnetic connection, threaded connection or snap-fit, which is both secure and easy to disassemble.

[0041] Optionally, when the counterweight 5 is magnetically connected to the cleaning head 1, the counterweight 5 can be directly magnetically attached to the surface of the cleaning head 1 near the auxiliary support 3. A groove 11 can also be formed on the surface of the cleaning head 1, and magnetic elements that magnetically attract each other can be provided in the groove 11 and on the surface of the counterweight 5. The counterweight 5 is fixed in the groove 11 by the magnetic attraction of the two magnetic elements; at least a magnetic element is provided on the bottom surface of the groove 11, and a corresponding magnetic element is provided on the surface of the counterweight 5.

[0042] Optionally, when the counterweight 5 is threadedly connected to the cleaning head 1, the counterweight 5 is cylindrical, the surface of the cleaning head 1 is provided with a groove 11, the side wall of the groove 11 is provided with a thread, the outer surface of the counterweight 5 is provided with a thread that matches the thread on the side wall of the groove 11, and the counterweight 5 is screwed into the groove 11.

[0043] Optional, such as Figure 4 and Figure 5 As shown, the counterweight 5 is snapped into the cleaning head 1. The surface of the cleaning head 1 has a groove 11, and the counterweight 5 can be snapped into the groove 11. The connection method is simple and easy to disassemble.

[0044] By setting a groove 11 on the surface of the cleaning head 1 to connect the counterweight 5, the surface of the counterweight 5 can be flush with the surface of the cleaning head 1 or slightly protrude from the surface of the cleaning head 1, making the cleaning head 1 neater and taking up less space.

[0045] like Figure 4 and Figure 5 As shown, a first slot 12 is formed on the first sidewall of the groove 11 of the cleaning head 1, and a second slot 13 is formed on the second sidewall of the groove 11 of the cleaning head 1, with the first and second sidewalls arranged opposite to each other; Figure 6 and Figure 7 As shown, the counterweight 5 is provided with a first buckle 52 that engages with the first slot 12 and a second buckle 53 that engages with the second slot 13. The first buckle 52 engages with the first slot 12, and the second buckle 53 engages with the second slot 13 to secure the counterweight 5 within the groove 11. This engagement of the slots and buckles ensures a secure connection between the counterweight 5 and the cleaning head 1, and facilitates easy disengagement. Preferably, the first slot 12 and the second slot 13 are positioned opposite each other on the center line of the cleaning head 1, and the first buckle 52 and the second buckle 53 are positioned opposite each other on the center line of the counterweight 5, ensuring a secure connection between the counterweight 5 and the cleaning head 1.

[0046] Optionally, the first latch 52 can slide relative to the counterweight 5. A second compression-type elastic element is provided along the sliding path of the first latch 52. One end of the second compression-type elastic element is connected to the first latch 52, and the other end is connected to the counterweight 5. The elastic deformation direction of the second compression-type elastic element is along the sliding direction of the first latch 52. When the first latch 52 slides closer to the counterweight 5, the second compression-type elastic element is compressed. The second compression-type elastic element can be a sheet or a spring. Without external force, the second compression-type elastic element is in its natural state, and the end of the first latch 52 protrudes beyond the edge of the counterweight 5 (e.g., ...). Figure 6 and Figure 7 (As shown in the diagram). When the counterweight 5 is installed into the groove 11 on the cleaning head 1, the second latch 53 first inserts into the second slot 13, and then moves the end of the counterweight 5 containing the first latch 52 towards the bottom of the groove 11, sliding the first latch 52 towards the counterweight 5 so that the end of the first latch 52 is flush with or recessed inward with the edge of the counterweight 5. At this time, the second compression elastic element is compressed. After the counterweight 5 is completely placed in the groove 11 on the cleaning head 1, the external force applied to the first latch 52 is released, and the second compression elastic element gradually returns to its initial state. The elastic force of the second compression elastic element drives the end of the first latch 52 to engage in the first slot 12, thus achieving engagement. Figure 6 and Figure 7As shown, the counterweight 5 is provided with a second guide groove 54 for accommodating the second compression type elastic element. When the second compression type elastic element is compressed, the first buckle 52 can also be completely accommodated in the second guide groove 54. The second guide groove 54 simultaneously restricts the compression direction of the second compression type elastic element and the sliding direction of the first buckle 52, so as to prevent the second compression type elastic element from tilting when it deforms.

[0047] When removing the counterweight 5 from the groove 11 of the cleaning head 1, first slide the first buckle 52 towards the counterweight 5 so that the first buckle 52 disengages from the first slot 12. Then remove the end of the counterweight 5 where the first buckle 52 is located from the groove 11, and the second buckle 53 disengages from the second slot 13, thus removing the counterweight 5 from the cleaning head 1.

[0048] For ease of operation, the first buckle 52 is provided with a second buckle protrusion 521, which facilitates the sliding of the first buckle 52 relative to the counterweight 5.

[0049] The end of the first latch 52 inserted into the first slot 12 can be arrow-shaped, i.e., formed by two inclined surfaces connected together. When the counterweight 5 is placed into the groove 11 of the cleaning head 1, the inclined surface of the first latch 52 near the cleaning head 1 first contacts the surface of the cleaning head 1. Then, as the counterweight 5 moves into the groove 11, the inclined surface acts as a guide, causing the first latch 52 to slide towards the counterweight 5. The second compression elastic element is compressed until the first latch 52 enters the first slot 12 and engages, at which point the second compression elastic element returns to its initial state. The inclined surface design allows the first latch 52 to engage with the first slot 12 without manual manipulation; the first latch 52 can engage under the interaction force. When removing the first latch 52 from the first slot 12, the other inclined surface of the first latch 52 also acts as a guide.

In one embodiment, the sludge suction mechanism can be a blower. A first air outlet can be provided on the sewage tank, and a second air outlet can be provided on the casing. The blower has an air inlet and an air outlet that are interconnected. The air inlet of the blower is connected to the first air outlet on the sewage tank, and the air outlet of the blower is connected to the second air outlet on the casing. When the blower is running, a negative pressure is formed at the sewage recovery port, so that sewage containing dissolved pollutants can sequentially enter the sewage tank through the sewage recovery port, the sewage channel, and the sewage inlet, allowing the sewage to be temporarily stored in the sewage tank. In another embodiment, the sludge suction mechanism can also be a pump body. The pump body is connected to the sewage tank and draws sewage containing dissolved pollutants into the sewage tank through the sewage recovery port, the sewage channel, and the sewage inlet under negative pressure.

[0056] In one embodiment, the handle 2 is connected to the main unit 200 via a connecting pipe 300. The connecting pipe 300 can be a rigid pipe or a deformable corrugated pipe. In another embodiment, the connecting pipe 300 can be inserted into the grip rod 21 of the handle 2. One end of the connecting pipe 300 is connected to the main unit 200, and the other end is connected to the cleaning head 1. The connecting pipe 300 has independent clean water channels and wastewater channels. A partition can be installed between the clean water channels and the wastewater channels to achieve isolation. One end of the clean water channel is connected to the spray nozzle, and the other end is connected to the clean water outlet of the clean water tank. One end of the wastewater channel is connected to the wastewater recovery port, and the other end is connected to the wastewater inlet of the wastewater tank. In another embodiment, one end of the connecting pipe 300 is connected to the main unit 200, and the other end is connected to the grip rod 21 of the handle 2. The connecting pipe 300 is connected to the cleaning head 1 through the grip rod 21 of the handle 2. The grip rod 21 has independent clean water channels and wastewater channels. The connecting pipe 300 has independent first clean water channels and first wastewater channels. The clean water outlet of the clean water tank, the first clean water channel, the clean water channel and the spray nozzle are connected in sequence. The wastewater recovery port, the wastewater channel, the first wastewater channel and the wastewater tank inlet are connected in sequence. The specific connection method between the connecting pipe 300 and the cleaning head 1 can be set according to actual needs. The connecting pipe 300 is detachably connected to the handle 2 and the main unit 200. The connecting pipe 300 is used to extend the distance between the main unit 200 and the handle 2. Users can selectively use the connecting pipe 300 according to actual needs. The handle 2 can be directly connected to the main unit 200, or the connecting pipe 300 can be connected between the handle 2 and the main unit 200.

[0057] The cleaning accessory 100 also includes a brush connected to the cleaning head 1. The brush is used to contact and clean the surface of the object being cleaned. The brush is located on the end face of the cleaning head 1 away from the handle 2, and the brush may be a nylon brush. The spray nozzle and wastewater collection port are positioned at a higher height relative to the surface of the object being cleaned than the brush is positioned relative to the surface of the object being cleaned, so that the brush is closer to the surface of the object being cleaned, thereby improving the user's cleaning efficiency. For example, the brush may be fixedly connected to the cleaning head 1 or may roll relative to the cleaning head 1.

[0058] When cleaning the surface of the object, the user holds the handle 2 and aligns the cleaning head 1 with the surface. The user controls the liquid supply mechanism to deliver clean water or a solution containing detergent from the clean water tank. The clean water or solution containing detergent passes through the clean water outlet and clean water channel of the clean water tank and then reaches the spray nozzle on the cleaning head 1, where it is sprayed onto the surface of the object. The user holds the handle 2 and moves the brush on the cleaning head 1 back and forth on the surface of the object, dissolving the stains in the solution. The user controls the operation of the sludge suction mechanism to generate negative pressure. The solution containing the dissolved dirt passes through the wastewater collection port, wastewater channel, and wastewater inlet on the wastewater tank of the cleaning head 1 and then enters the wastewater tank, thus collecting the wastewater containing the dissolved dirt into the wastewater tank and cleaning the surface of the object.

[0059] The cleaning equipment can be a fabric cleaning machine or a device containing a fabric module; this application does not limit it to a single type.

[0060] When cleaning a horizontal surface, the user can adjust the weight of the counterweight 5 according to the usage situation. For example, the user can change the material of the counterweight 5, adjust the type of counterweight medium inside the counterweight 5, or adjust the amount of counterweight medium inside the counterweight 5, so that the counterweight 5 provides downward pressure to completely or partially replace the downward pressure of the human hand. Rotate the auxiliary support 3 to the second position, and the auxiliary support 3 supports the surface of the object being cleaned, providing support force and reducing user fatigue. The user only needs to apply a small force to push and pull the cleaning head 1, so that the cleaning head 1 reciprocates on the surface of the object being cleaned.

[0061] When cleaning a vertical surface, the counterweight 5 can be removed from the cleaning head 1 to reduce weight, or the auxiliary support 3 can be rotated to the first position for easy operation of the cleaning head 1.

[0062] When cleaning the surface of an object in a narrow area, rotate the auxiliary bracket 3 to the first position, which is in a retracted state, so that the cleaning head 1 can rotate flexibly without interfering with the cleaning operation of the cleaning head 1.

[0063] The cleaning equipment of this application, through the design of auxiliary supports and counterweights in the cleaning accessories, can be flexibly changed according to the usage scenario, reducing user fatigue.
