[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] The core of this utility model is to provide a scraping structure that allows the deformable part of the scraping component to be movably configured. This enables the position of the deformable part of the scraping component to adapt to uneven surfaces or when the scraping component and related structures require cleaning, thereby meeting the user's needs. Another core aspect of this utility model is to provide a cleaning brush and wet cleaning equipment that includes the aforementioned scraping structure.

[0043] The scraping structure provided by this utility model includes a base plate 3, a movable plate 5, a scraping component 4, and a first elastic component 1. Please refer to [reference needed]. Figure 1 .

[0044] Please refer to Figure 6 , Figure 8 Specifically, the scraping structure provided by this utility model can be used in conjunction with the dirt collection structure 8 and the roller brush assembly 9 to perform floor cleaning work. Specifically, the roller brush assembly 9 can remove dry garbage, dust and wet garbage on the surface to be cleaned 10 by rotating and mix it with clean water to form mixed sewage. The scraping structure contacts the surface to be cleaned 10 to scrape off the mixed sewage. The mixed sewage can be absorbed into the dirt collection structure 8 under negative pressure.

[0045] The substrate 3 is specifically fixed to the dirt collection structure 8. The specific fixing method is achieved by fasteners, such as screws, nuts, bolts, pins, etc.; the specific fixing method can also be achieved by snap-fit, that is, the substrate 3 can be fixed to the dirt collection structure 8 by snap-fit. The above fixing methods are only examples. The fixing methods that can achieve detachable connection between the substrate 3 and the dirt collection structure 8 and can reliably fix the two are all within the protection scope of this utility model.

[0046] The movable plate 5 includes a rotating connecting part 52 and a receiving groove 51 away from the rotating connecting part 52. The rotating connecting part 52 can rotate relative to the base plate 3. Please refer to [reference needed]. Figure 5 .

[0047] In one specific embodiment, the substrate 3 and the dirt collection structure 8 are fixedly connected, and the rotating connection part 52 is rotatably connected to the substrate 3 so as to realize the rotation of the rotating connection part 52 relative to the substrate 3.

[0048] In another specific embodiment, the substrate 3 and the dirt collection structure 8 are fixedly connected, and the rotating connection part 52 is rotatably connected to the dirt collection structure 8 so as to realize the rotation of the rotating connection part 52 relative to the substrate 3.

[0049] In the two specific implementation methods described above, the form of the rotating connection can be a ball joint, shaft joint, or other similar forms, without much restriction.

[0050] The receiving groove 51 can provide space for at least a portion of the deformable part 42 to move in. The specific groove structure can be designed according to the actual structural adaptability of the deformable part 42, and no specific restrictions are made here.

[0051] The scraping component 4 includes a first fixing part 41, a deformable part 42, a second fixing part 44, and a scraping part 45. Please refer to [reference needed]. Figure 1 .

[0052] The first fixing part 41 is fixedly connected to the base plate 3, and the second fixing part 44 is fixedly connected to the movable plate 5. Specifically, the first fixing part 41 is connected to the base plate 3 by means of a snap-fit ​​connection, such as... Figure 1 As shown, this design allows for reliable connection while facilitating the assembly and disassembly of the scraping component 4 relative to the base plate 3; similarly, the second fixing part 44 is connected to the movable plate 5 via a snap-fit ​​mechanism, such as... Figure 1 As shown, specifically, the second fixing part 44 can make contact with the outer periphery of the movable plate 5 through the horizontal part and the vertical part to achieve a fixing effect. It can also facilitate the assembly and disassembly of the scraping part 4 relative to the movable plate 5 and maintain a reliable connection.

[0053] The deformable part 42 is located between the first fixed part 41 and the second fixed part 44, and the scraping part 45 is located on the side of the second fixed part 44 away from the deformable part 42.

[0054] like Figure 1 As shown, the scraping section 45 is the part of the scraping component 4 that is scraped. It can reliably contact the surface 10 to be cleaned to perform scraping operations, and together with the roller brush assembly 9, it achieves the effect of cleaning the surface 10 to be cleaned.

[0055] The first fixing part 41 and the second fixing part 44 are both fixed relative to each other, while the deformable part 42 located between the first fixing part 41 and the second fixing part 44 has a first position state and a second position state. Switching between these two position states can realize the overall mobility of the scraping part 4.

[0056] Specifically, the first elastic member 1 connected to the movable plate 5 provides a downward rotational elastic torque, which can be applied to the deformable part 42 through the movable plate 5 to facilitate the switching of the position state of the deformable part 42.

[0057] like Figure 7 When the scraping part 45 of the scraping member 4 contacts the surface 10 to be cleaned, the movable plate 5 is in a state parallel to the surface 10 to be cleaned. The downward torque provided by the first elastic member 1 enables the scraping part 45 to reliably adhere to the surface 10 to be cleaned, and enables the deformable part 42 to be in a first position state, that is, at least a portion of the deformable part 42 is accommodated in the receiving groove 51, ensuring a reliable scraping effect of the scraping member 4. In this case, the scraping member 4 is in a state close to the roller brush assembly 9.

[0058] like Figure 9 When the scraping part 45 of the scraping member 4 moves away from the surface 10 to be cleaned, the downward torque provided by the first elastic member 1 causes the movable plate 5 to rotate relative to the base plate 3. As the movable plate 5 rotates, the deformable part 42 located in the receiving groove 51 of the movable plate 5 moves out of the receiving groove 51 under the action of the deformation force, that is, the deformable part 42 is in a second position outside the receiving groove 51. During this process, the scraping part 45 of the scraping member 4 moves away from the roller brush assembly 9, making it less likely for the scraping member 4 and the roller brush assembly 9 to interfere with each other, which facilitates the cleaning of mixed wet waste from the scraping member 4 and related structures, such as the roller brush assembly 9. Specifically, the scraping part 45 moves away from the surface 10 to be cleaned in either the state where the dirt collection structure 8 is lifted or the state where the scraping structure is assembled.

[0059] In this embodiment, the first elastic member 1 can always provide a downward flipping force to the movable plate 5. In the cleaning operation state of the surface to be cleaned 10, the scraper 4 can reliably adhere to the surface to be cleaned 10 to ensure the cleaning effect. In the garbage cleaning state, the scraper 4 can be moved away from the roller brush assembly 9 to avoid interference and facilitate the wet garbage cleaning operation.

[0060] In this embodiment, the deformable portion 42 of the scraper 4 can be at least partially received in or removed from the receiving groove 51, allowing the scraper 4 to move relative to the movable plate 5. In one case, the scraper 4 can be removed simultaneously when the dirt collection structure 8 is removed, and then the scraper 4 can be disassembled for garbage cleaning operations; in another case, the deformable portion 42 of the scraper 4 moves out of the receiving groove 51, and the garbage cleaning operation of the scraper 4 can be performed directly without disassembling the scraper 4.

[0061] Furthermore, the scraping structure also includes a second elastic member 6, one end of which is fixedly connected to the substrate 3 and the other end is connected to the deformation part 42. The second elastic member 6 provides tension to the deformation part 42.

[0062] Specifically, when the deformable part 42 switches from the first position state to the second position state, in the state of the dirt collection structure 8 being lifted or the state of the scraping structure being assembled, under the action of the downward elastic torque of the first elastic member 1, the side of the movable plate 5 and the scraping member 4 that is in contact with the surface 10 to be cleaned rotates downward. When the deformable part 42 moves out of the receiving groove 51, the second elastic member 6 is stretched. When the deformable part 42 switches from the second position state to the first position state, after the scraping part 45 of the scraping member 4 contacts the surface 10 to be cleaned, the stretching force of the second elastic member 6 can provide the restoring force for the deformable part 42 to move into the receiving groove 51. After the deformable part 42 moves into the receiving groove 51, the second elastic member 6 returns to its original state.

[0063] Furthermore, the use of the second elastic member 6 and the first elastic member 1 in combination can balance each other. The downward elastic torque provided by the first elastic member 1 can reliably and effectively stretch the second elastic member 6 to obtain the restoring force for the deformed part 42 to move into the receiving groove 51.

[0064] Furthermore, such as Figure 4 The first fixing part 41 extends to the side of the movable plate 5 and is provided with a first connecting part 46. A connecting groove 31 is provided on the base plate 3 at the position corresponding to the first connecting part 46. A second connecting part 32 is provided in the connecting groove 31. The two ends of the second elastic member 6 are respectively connected to the first connecting part 46 and the second connecting part 32.

[0065] Specifically, the first connecting portion 46 is independent of the first fixing portion 41 and does not need to be processed on the first fixing portion 41, which facilitates the connection of the second elastic member 6. The second connecting portion 32 on the substrate 3 is specifically located in the connecting groove 31. One end of the second elastic member 6 extends into the connecting groove 31 and is connected to the second connecting portion 32, while the other end of the second elastic member 6 is directly connected to the first connecting portion 46.

[0066] Specifically, the first connecting part 46 and the second connecting part 32 can be configured as a hanging ear, a hanging ring, or the like, which can provide an area for the second elastic member 6 to be attached, and enable the second elastic member 6 to be reliably connected between the scraping member 4 and the substrate 3.

[0067] When the second elastic member 6 is in the retracted state, it is located in the connecting groove 31, corresponding to the scraping part 45 of the scraping member 4 contacting the surface to be cleaned 10, and is in the working state of scraping the surface to be cleaned 10; when the second elastic member 6 is in the stretched state, it extends out of the connecting groove 31. Specifically, the end connected to the first fixing part 41 extends out of the connecting groove 31, corresponding to the scraping part 45 of the scraping member 4 moving away from the surface to be cleaned 10, and is in the working state of cleaning the wet waste of the scraping member 4 and its associated structure.

[0068] By providing a connecting groove 31 on the base plate 3, the second elastic member 6 can be limited when the movable plate 5 rotates, thus restricting the range of motion of the second elastic member 6 and ensuring reliable operation. Specifically, the edge of the connecting groove 31 extends beyond the edge of the second elastic member 6, and the structure can be flexibly configured according to actual conditions.

[0069] For further details, please refer to... Figure 2 , Figure 9 The scraping component 4 includes an abutment portion 43, which is located on the side of the scraping component 4 away from the movable plate 5.

[0070] When the deformable part 42 is in the first position, the abutting part 43 abuts against the dirt collection structure 8 and blocks the substrate 3. Simultaneously, the abutting part 43 abuts against the sloped surface of the substrate 3, providing a positioning reference for the deformable part 42 to move into the receiving groove 51. Specifically, the abutting part 43 blocks the substrate 3 by sealing the interface where the substrate 3 and the dirt collection structure 8 are fixedly connected, thus preventing wet waste, water, or other impurities from entering the deformable part 42 and the substrate 3 during the scraping operation.

[0071] In addition, the scraping part 4 is a soft rubber-coated part, and the corresponding abutment part 43 has softness. The movable plate 5 is connected to the substrate 3 and the dirt collection structure 8 in a soft connection through the abutment part 43, which can effectively reduce the collision damage of the substrate 3 and the dirt collection structure 8, and can effectively reduce the noise when the position state of the deformation part 42 is switched.

[0072] For further details, please refer to... Figure 2 The thickness of the portion of the deformable part 42 corresponding to the edge of the receiving groove 51 is less than the thickness of the portion of the deformable part 42 corresponding to the inside of the receiving groove 51.

[0073] Specifically, the deformable part 42 is set to have unequal wall thickness, with a thinner thickness at the corners where the deformable part 42 deforms. This ensures that the deformable part 42 moves and deforms according to a preset trajectory, guaranteeing the reliability and effectiveness of the switching between the first and second position states of the deformable part 42.

[0074] Please refer to Figure 1 The edge of the receiving groove 51 or the inner wall of the receiving groove 51 is provided with a transition surface 511, which is used for the transition of the deformable part 42 into the receiving groove 51. The transition surface 511 here specifically refers to a slope / arc surface, which enables the deformable part 42 to smoothly enter the receiving groove 51 and move and deform according to a preset trajectory.

[0075] The edge of the specific receiving groove 51 or the inner sidewall of the receiving groove 51 can be provided with a transition surface 511, which can be set with a single edge / double edge or a single sidewall / double sidewall, depending on the actual design requirements.

[0076] In addition to the aforementioned scraping structure, this utility model also provides a floor cleaning brush, which specifically includes: a brush housing 11, a roller brush assembly 9, and a detachable component. Please refer to [reference needed]. Figure 6 , Figure 8 The detachable component is detachably connected to the floor brush housing 11, and the detachable component includes the swiping structure described in the above embodiments.

[0077] The detachable component can be removed from the brush housing 11 to facilitate cleaning or maintenance of the brush structure; the detachable component can also be installed on the brush housing 11 to facilitate the assembly of the cleaning brush.

[0078] It should be noted that when the detachable component is installed on the floor brush housing 11, since the deformation part 42 corresponding to the scraping component 4 of the scraping structure has a first position shape and a second position shape, even if the scraping component 4 is not removed from the floor brush housing 11, the scraping component 4 can be positioned close to or away from the roller brush assembly 9, which can also avoid interference when cleaning garbage and ensure the effect of garbage cleaning.

[0079] The roller brush assembly 9 is located at the front of the floor brush housing 11. When the detachable assembly is installed in place with the floor brush housing 11, the scraping structure is located at the rear of the roller brush assembly 9. Here, "front" and "rear" are defined based on the direction of travel of the cleaning brush. The roller brush assembly 9 can remove dry debris, dust, and wet debris from the surface 10 to be cleaned by rotating, while the scraping structure works in conjunction with the roller brush assembly 9 to draw wastewater and dust into the dirt collection structure 8.

[0080] Furthermore, the detachable component includes a dirt collection structure 8, with the base plate 3 fixedly connected to the dirt collection structure 8, and a rotating connection part 52 rotatably connected to a rotating shaft 2 to enable the movable plate 5 to rotate relative to the base plate 3 and the dirt collection structure 8.

[0081] The rotating shaft 2 is fixed to the dirt collection structure 8 or the base plate 3. When the rotating shaft 2 is fixed to the dirt collection structure 8, the rotating connection part 52 and the dirt collection structure 8 are rotatably connected via the rotating shaft 2. When the rotating shaft 2 is fixed to the base plate 3, the rotating connection part 52 and the base plate 3 are rotatably connected via the rotating shaft 2. The rotating shaft 2 can be a single shaft section or a multi-segment shaft, and its configuration can be flexibly adjusted based on the actual spatial arrangement and the required number of first elastic elements 1.

[0082] like Figure 1 , Figure 2 , Figure 5 As shown, the first elastic element 1 is sleeved on the rotating shaft 2. The first elastic element 1 can be specifically a torsion spring. The main body of the first elastic element 1 is sleeved on the rotating shaft 2, one end is fixed to the side of the movable plate 5 away from the scraper 4, and the other end is pressed on the side of the movable plate 5 close to the scraper 4, so as to provide elastic torque to move the deformable part 42 out of the receiving groove 51, that is, to provide elastic torque to move the scraper 4 away from the roller brush assembly 9 to avoid interference.

[0083] The first elastic element 1 is pressed onto one end of the movable plate 5 and can be limited by a limiting groove. Specifically, a limiting groove is set on the movable plate 5. When the first elastic element 1 provides downward torque, this end is always located in the limiting groove, which can prevent the first elastic element 1 from deviating from the limiting groove and ensure the reliable and safe operation of the first elastic element 1.

[0084] Furthermore, the movable plate 5 is provided with a rotating connection part 52 for rotating connection with the sewage collection structure 8, and the rotating shaft 2 is disposed through the rotating connection part 52 and the first elastic member 1.

[0085] The rotating shaft 2 passes directly through the rotating connection part 52 and the first elastic element 1, so that the rotating shaft 2 can provide conditions for the movable plate 5 to rotate on the one hand, and conditions for the first elastic element 1 to be installed on the other hand. It serves multiple purposes, reduces the number of parts, simplifies the structure, and makes the overall scraping structure compact.

[0086] Furthermore, a rotating wheel 7 is provided on the side of the movable plate 5 away from the base plate 3. When the cleaning brush is in working state, the rotating wheel 7 contacts the flat surface to be cleaned 10, and the deformable part 42 is in the first position state.

[0087] The rotating wheel 7 is specifically a wheel that can travel on the surface 10 to be cleaned. When the cleaning brush is lifted or assembled, the rotating wheel 7 is in a state away from the surface 10 to be cleaned. Correspondingly, the movable plate 5 can rotate downward under the force of the first elastic member 1, so that the side of the scraper 4 that contacts the surface 10 to be cleaned is away from the roller brush assembly 9, so as to facilitate the cleaning of debris on the scraper 4 and the roller brush assembly 9. When the rotating wheel 7 changes from a state away from the surface 10 to a state that contacts the surface 10 to be cleaned, the side of the movable plate 5 with the receiving groove 51 and the side of the scraper 4 that contacts the surface 10 to be cleaned can both rotate toward the roller brush assembly 9, so that the deformable part 42 can at least partially move into the receiving groove 51. In this case, due to the contact between the rotating wheel 7 and the surface to be cleaned 10, the movable plate 5 can be forced to rotate upward, and at least part of the deformable part 42 can be inserted into the receiving groove 51. Under the torque of the first elastic member 1, the deformable part 42 can be in the first position state, which can keep the scraping part 45 of the scraping member 4 and the surface to be cleaned 10 in reliable contact, and ensure the scraping effect.

[0088] Specifically, two, three or more rotating wheels 7 can be set. Specifically, the space for the rotating wheels 7 is left on the movable plate 5, the shaft is installed in this space, and then the rotating wheels 7 are reliably installed inside.

[0089] For further details, please refer to... Figure 9 The radius of the roller brush assembly 9 is R, and the horizontal distance from the axis of the roller brush assembly 9 to the scraping part 45 is L. The relationship between L and R satisfies the condition L≤R, so as to avoid interference between the roller brush assembly 9 and the scraping part 45 when disassembling and assembling the dirt collection structure 8, and facilitate the cleaning operation of the scraping part 4.

[0090] In addition to the aforementioned floor cleaning brush, this utility model also provides a wet cleaning device, specifically including the floor cleaning brush, main body, liquid supply device, and negative pressure generating device described in the above embodiments.

[0091] The liquid supply device is located on the main body or the cleaning brush and is used to provide cleaning liquid, such as water or a mixture of water and cleaning liquid. If the liquid supply device is detachably mounted on the brush housing 11 of the cleaning brush, or if the liquid supply device is detachably mounted on the main body, the liquid supply device can be installed and removed in a detachable manner, so that the liquid supply device can be removed separately for cleaning or refilling of cleaning liquid.

[0092] The cleaning liquid supplied by the liquid supply device is specifically provided to the surface 10 to be cleaned and / or the roller brush assembly 9, depending on the actual cleaning needs. If the surface 10 to be cleaned is heavily soiled, the cleaning liquid can be supplied to both the surface 10 and the roller brush assembly 9 simultaneously to ensure the cleaning effect of the surface 10.

[0093] A negative pressure generating device is located on the main body or the cleaning brush, specifically detachably mounted on the brush housing 11 of the cleaning brush, or directly detachably mounted on the main body. This device provides a negative pressure air environment for the dirt collection structure. Specifically, the negative pressure generated by the device draws the dirt cleaned by the cleaning brush into the dirt collection structure 8, achieving either suction or retention of the dirt. If dirt remains in the dirt collection structure 8, it can be discharged and cleaned after the cleaning operation is completed.
