Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0043] In order to solve the problem that the sewage outlet of the scraper of the cleaning device is easily blocked by garbage, according to an embodiment of the present invention, a cleaning device is provided. The cleaning device of the present application will be described in detail below with reference to the accompanying drawings.

[0044] See also Figures 1 to 14 As shown, according to an embodiment of the present application, a cleaning device is provided, which includes a main body 10, a cleaning member 20, a scraper assembly 30 and a filter assembly 40.

[0045] The cleaning element 20 is rotatably mounted on the bottom of the main unit 10. A scraper assembly 30 is mounted on the bottom of the main unit 10 and located to the side of the cleaning element 20 to at least scrape away debris attached to the cleaning element 20. The scraper assembly 30 is provided with a sewage outlet 311. A filter assembly 40 is disposed at and covers the sewage outlet 311.

[0046] In the present application, the waste outlet 311 of the scraper assembly 30 is provided with a filter assembly 40 covering the waste outlet 311. This allows the cleaning device of the present application to solve the problem of the waste outlet 311 of the cleaning device being easily blocked by garbage. During actual operation, the main body 10 can move. During the movement of the main body 10, the cleaning member 20 can rotate to remove garbage from the surface in contact with the cleaning member 20 (such as the ground or the edge of the countertop). It is understood that the garbage in this embodiment includes at least one of hair, dust, debris, and sewage. At the same time, during the rotation of the cleaning member 20, the scraper assembly 30 provided on the side of the cleaning member 20 can scrape the garbage on the cleaning member 20. The garbage can then flow into the waste collection tank of the cleaning device through the waste outlet 311. At this time, because the waste outlet 311 is covered by the filter assembly 40, the filter assembly 40 can filter the garbage scraped by the scraper assembly 30, thereby preventing large garbage from blocking the waste outlet 311 and affecting the normal operation of the cleaning device.

[0047] That is to say, compared with the existing cleaning device, the cleaning device of the present application can solve the problem that the sewage outlet 311 of the cleaning device is easily blocked by garbage by setting a filter component 40 at the sewage outlet 311, and has the advantages of simple structure and low cost.

[0048] Further, see Figures 1 to 14 As shown, in some embodiments of the present application, the filter assembly 40 is fixedly arranged at the sewage outlet 311 (such as Figures 2 to 6 In some other embodiments of the present application, the filter assembly 40 can also be floated at the sewage outlet 311 to at least be used to spit out the garbage attached to the sewage outlet 311 toward the direction close to the cleaning member 20 when the cleaning member 20 rotates in a predetermined direction (as shown in FIG. Figure 1 、 Figures 7 to 14 As shown). It is understood that the floating arrangement described in the present application can be a rotational motion, a translational motion, or a combination of rotational and translational motions. In addition, the cleaning member 20 of the present application particularly refers to a drum, and when the drum rotates, the side of the drum can perform cleaning work.

[0049] That is to say, the filter assembly 40 and the scraper assembly 30 of the present application can be fixedly connected or floatingly connected. When the filter assembly 40 and the scraper assembly 30 are fixedly connected, such as Figure 3 As shown, during the movement of the host 10, the cleaning member 20 moves in a counterclockwise direction (i.e. Figure 3When the cleaning device completes the cleaning work, the cleaning member 20 can be rotated in the clockwise direction (i.e., the direction indicated by b in the figure). At this time, the cleaning member 20 can not only perform the cleaning work, but also make the garbage and sewage attached to the side of the cleaning member 20 be scraped off by the scraper assembly 30. Due to the function of the filter assembly 40, the garbage can be filtered by the filter assembly 40 to prevent the sewage outlet 311 from being blocked by garbage. Figure 3 When the filter assembly 40 and the scraper assembly 30 are connected in a floating manner, the garbage attached to the filter assembly 40 can be swept away by the cleaning member 20, so that the filter assembly 40 can be cleaned. Figure 12 As shown, the filter assembly 40 can be connected to the scraper assembly 30 by sliding, or by rotating, or by a combination of sliding and rolling connections. Figure 3 The cleaning member 20 can rotate in the direction indicated by b in the figure. While performing the cleaning task, the scraper assembly 30 can also scrape away the garbage attached to the side of the cleaning member 20. The filter assembly 40 can filter the garbage generated during the cleaning process to prevent the garbage from blocking the sewage outlet 311. After the cleaning device completes the cleaning work, the cleaning member 20 can be rotated in the clockwise direction (i.e., the predetermined direction mentioned above, i.e., Figure 3 The cleaning member 20 can further clean the garbage in the filter assembly 40 during the clockwise rotation process, so as to achieve the purpose of cleaning the garbage in the filter assembly 40 and the scraper assembly 30.

[0050] Specifically, see Figures 2 to 6 As shown, at least one of the filter assembly 40 and the scraper assembly 30 is rotatably disposed at the bottom of the main unit 10 and located on the side of the cleaning member 20, and the scraper assembly 30 is fixedly connected to the filter assembly 40, so that the filter assembly 40 can be fixedly disposed at the sewage outlet 311.

[0051] For example, in the present application, first, the filter assembly 40 can be rotated and set at the bottom of the main unit 10, or the scraper assembly 30 can be rotated and set at the bottom of the main unit 10. Alternatively, both the filter assembly 40 and the scraper assembly 30 can be rotated and set at the bottom of the main unit 10, and then the scraper assembly 30 and the filter assembly 40 are fixedly connected together. Figures 2 to 6The first embodiment of the present application is shown. The first embodiment shows a case where the filter assembly 40 is rotated and arranged at the bottom of the main body 10, and then the scraper assembly 30 is fixedly connected to the filter assembly 40. In this way, the scraper assembly 30 can rotate with the filter assembly 40, and during the rotation process, the filter assembly 40 can always cover the sewage outlet 311. The garbage that needs to flow through the sewage outlet 311 can first be filtered by the filter assembly 40, and then flow through the sewage outlet 311 to the sewage collection box (not shown in the figure) of the cleaning device, thereby preventing the sewage outlet 311 from being blocked by garbage.

[0052] Further, see Figures 3 to 6 As shown, the cleaning device further includes a first rotating shaft 50 , which is located at the bottom of the main body 10 . At least one of the filter assembly 40 and the scraper assembly 30 is sleeved on the first rotating shaft 50 and can rotate around the first rotating shaft 50 .

[0053] Specifically, in the first embodiment of the present application, the scraper assembly 30 is fixedly connected to the filter assembly 40. First, the operator sets the first rotating shaft 50 at the bottom of the main unit 10 and on the side of the cleaning member 20, then sets the filter assembly 40 on the first rotating shaft 50, and arranges a plurality of force-applying torsion springs 51 at intervals on the first rotating shaft 50, and can press one end of the force-applying torsion spring 51 against the filter assembly 40, and press the other end of the force-applying torsion spring 51 against the main unit 10, and finally fix the scraper assembly 30 to the filter assembly 40. In actual operation, the cleaning member 20 moves counterclockwise (i.e. Figure 3 When the cleaning device completes its cleaning work, the cleaning device 20 can be rotated in the clockwise direction (in the direction indicated by b in the figure). Due to the elastic force of the torsion spring 51, the filter assembly 40 and the scraper assembly 30 can fit more closely to the side of the cleaning member 20. Therefore, the cleaning member 20 can not only perform cleaning work while rotating, but also make the garbage attached to the side of the cleaning member 20 be scraped off by the scraper assembly 30. The scraped garbage is filtered by the filter assembly 40 and then collected into the garbage collection box of the cleaning device through the sewage outlet 311. Figure 3 Since the filter assembly 40 and the scraper assembly 30 are in contact with the side of the cleaning member 20, the garbage attached to the filter assembly 40 and the scraper assembly 30 can be swept away by the cleaning member 20, thereby cleaning the filter assembly 40 and the scraper assembly 30.

[0054] In addition, in order to improve the filtering effect of the filter assembly 40, the structure of the filter screen 41 of the present application can be reasonably designed according to the structure of the scraper assembly 30, so that the filter screen 41 can better cover the sewage outlet 311, thereby improving the filtering effect of the filter screen 41. In the first embodiment of the present application, the filter screen 41 is in the shape of a long strip (such as Figure 5As shown), and along the length direction perpendicular to the filter 41 (ie Figure 5 When the filter screen 41 is cut along the direction indicated by x in the figure, the cross-section of the filter screen 41 is curved. This configuration allows the filter screen 41 to better fit the scraper assembly 30 of the first embodiment. In other embodiments of the present application, the structure of the filter screen 41 can be reasonably designed based on the structure of the scraper assembly 30, thereby solving the problem of the sewage outlet 311 of the cleaning device being easily blocked by garbage.

[0055] Further, see Figure 1 、 Figures 7 to 14 As shown, the filter assembly 40 includes a filter screen 41, a resisting member 42, and an elastic element 43. The filter screen 41 is movably mounted on the scraper assembly 30 and covers the sewage outlet 311. The resisting member 42 is rotatably mounted on the scraper assembly 30 and has a resisting top 421 that protrudes from the scraper assembly 30. The elastic element 43 resists between the resisting member 42 and the scraper assembly 30, thereby completing the floating arrangement of the filter assembly 40. When the cleaning element 20 rotates in a predetermined direction, the cleaning element 20 drives the scraper assembly 30 to rotate and causes the resisting top 421 to resist the main body 10. The resisting member 42 rotates to push the filter screen 41 to spit out garbage attached to the sewage outlet 311 toward the cleaning element 20.

[0056] Specifically, Figure 1 、 Figures 7 to 14 The second embodiment of the present application is shown. The cleaning device of the second embodiment has a similar structure to that of the first embodiment. The cleaning device of the second embodiment also includes a main unit 10, a cleaning member 20, a scraper assembly 30, and a filter assembly 40. However, unlike the first embodiment, the filter assembly 40 of the second embodiment is connected to the scraper assembly 30 by a floating connection, and the filter screen 41 is movably arranged on the scraper assembly 30 and covers the sewage outlet 311. In actual operation, see Figures 11 to 12 As shown, after the cleaning device completes the cleaning work, the cleaning member 20 moves in a clockwise direction (i.e., the predetermined direction mentioned above, i.e., Figure 3The scraper assembly 30 and the filter assembly 40 rotate in a clockwise direction (in the direction indicated by a in the figure), driven by the cleaning element 20. As the filter assembly 40 rotates, the abutting top 421 of the abutting member 42 abuts the bottom of the main unit 10. At this time, under the combined action of the cleaning element 20 and the main unit 10, the abutting member 42 rotates counterclockwise relative to the scraper assembly 30. The other end of the abutting member 42 opposite the abutting top 421 contacts the filter 41. As the abutting member 42 rotates counterclockwise, it pushes the filter 41 toward the cleaning element 20, ultimately discharging the waste attached to the sewage outlet 311 toward the cleaning element 20. After the waste is discharged, the cleaning element 20 stops rotating. At this time, the elastic element 43 allows the abutting member 42 to return to its static position.

[0057] Further, see Figures 7 to 10 As shown, the filter screen 41 includes a mesh body 411, a stop section 412 and a connecting section 413. A limiting hole 312 is provided on the scraper assembly 30. The connecting section 413 is passed through the limiting hole 312 and can move within the limiting hole 312. The mesh body 411 is connected to the first end of the connecting section 413. The stop section 412 is located at the second end of the connecting section 413 opposite to the first end. The mesh body 411 and the stop section 412 limit the connecting section 413 to the scraper assembly 30.

[0058] Specifically, the mesh body 411 mainly covers the sewage outlet 311 to filter garbage and sewage, and the stop section 412 can limit the filter screen 41 on the scraper assembly 30 to prevent it from falling. At the same time, the stop section 412 can also prevent the filter screen 41 from tilting up during movement. If the stop section 412 is not provided, when the supporting component 42 pushes the filter screen 41 to move, it is easy to cause the mesh body 411 and the sewage outlet 311 to not fit tightly. At this time, garbage can easily fall into the sewage outlet 311 from the gap between the mesh body 411 and the sewage outlet 311, and easily block the sewage outlet 311. Therefore, the stop section 412 is provided on the filter screen 41. Furthermore, the limiting holes 312 on the scraper assembly 30 can also prevent the mesh 411 from being loosely attached to the drain outlet 311 during the movement of the filter 41. The structure of the stopper section 412 can be configured to align with the limiting holes 312, so that the mesh 411 can always be attached to the drain outlet 311 during the movement of the filter 41. Furthermore, the limiting holes 312 can also limit the movement of the filter 41, preventing the filter 41 from being unable to return to its original position due to excessive movement.

[0059] Further, see Figure 8As shown, the scraper assembly 30 includes a scraper body 31 and a connecting plate 32. The connecting plate 32 is rotatably set at the bottom of the main body 10. The scraper body 31 is detachably connected to the connecting plate 32. The limiting hole 312 and the sewage outlet 311 are both set on the scraper body 31. The mesh body 411 is located on the side of the scraper body 31 close to the cleaning part 20, and the stop section 412 is located on the side of the scraper body 31 away from the cleaning part 20.

[0060] Specifically, the connecting plate 32 is sleeved on the first rotating shaft 50, and a plurality of force-applying torsion springs 51 are arranged at intervals on the first rotating shaft 50. One end of the force-applying torsion spring 51 can be pressed against the connecting plate 32, and the other end of the force-applying torsion spring 51 can be pressed against the main unit 10, and then the scraper body 31 is connected to the connecting plate 32. The provision of the connecting plate 32 can not only make the structure of the scraper body 31 simpler and facilitate the processing of the scraper body 31, but also make the disassembly of the scraper body 31 more convenient. If the connecting plate 32 is not provided, when the scraper body 31 needs to be disassembled for deep cleaning, the first rotating shaft 50 needs to be disassembled from the main unit 10 first, and then the scraper body 31 can be disassembled. Not only that, the way in which the scraper body 31 and the connecting plate 32 are arranged separately also makes processing easier, which can save production costs to a certain extent. In addition, the combined action of the mesh body 411 and the stop section 412 enables the filter screen 41 to be floatingly connected to the scraper body 31. With such a configuration, when the supporting component 42 rotates counterclockwise, it can push the filter screen 41 toward the direction close to the cleaning element 20, and finally spit out the garbage attached to the sewage outlet 311 toward the direction close to the cleaning element 20.

[0061] Further, see Figures 8 to 10 As shown, the stop section 412 is arranged in a long strip shape, and the connecting section 413 and the limiting hole 312 both include multiple, multiple connecting sections 413 are arranged in sequence along the length direction of the stop section 412, and the multiple connecting sections 413 are correspondingly passed through the multiple limiting holes 312 one by one, and the mesh body 411 is fixedly connected to each connecting section 413.

[0062] Specifically, the length direction of the stop section 412 is Figure 9 In the direction indicated by y, the connecting segments 413 may include two, three or more than three. Correspondingly, the limiting holes 312 may also include two, three or more than three. In the second embodiment of the present application, the case where both the connecting segments 413 and the limiting holes 312 include two is shown. In the present application, the shape of the connecting segments 413 can be reasonably adjusted according to actual needs. The connecting segments 413 can be straight strips or curved strips. The second embodiment of the present application shows that each connecting segment 413 is an "s"-shaped curved strip (such as Figure 10), and the stop segment 412 is located at the end of the connecting segment 413 facing away from the mesh body 411. In the present application, the stop segments 412 can be interconnected or not. The second embodiment of the present application shows a case where the stop segments 412 are interconnected. Moreover, the interconnection between the stop segments 412 also has the advantage of making the structure of the filter 41 more stable. In addition, the structural design in which the connecting segment 413 is inserted into the limiting hole 312 and the stop segment 412 and the mesh body 411 are respectively located at the two ends of the connecting segment 413 can ensure that the filter 41 is not easily dropped from the scraper body 31 during movement.

[0063] Further, see Figures 11 to 14 As shown, the cleaning device further includes an elastic reset member 60 , which is disposed between the filter screen 41 and the scraper assembly 30 to apply a reset elastic force to the filter screen 41 .

[0064] Specifically, the setting of the elastic reset member 60 can not only apply a reset elastic force to the filter 41, but also prevent the filter 41 from being too close to the cleaning member 20 and affecting the normal operation of the cleaning member 20. At the same time, the number of elastic reset members 60 can be reasonably adjusted according to actual needs. In the second embodiment of the present application, two elastic reset members 60 are provided between the filter 41 and the scraper assembly 30. In actual operation, the cleaning member 20 moves in a clockwise direction (i.e. Figure 3 The scraper assembly 30 and filter assembly 40 rotate clockwise under the drive of the cleaning element 20. As the filter assembly 40 rotates, the abutting top 421 of the abutting member 42 abuts against the bottom of the main unit 10. At this point, under the combined action of the cleaning element 20 and the main unit 10, the abutting member 42 rotates counterclockwise relative to the scraper assembly 30, pushing the filter 41 toward the cleaning element 20, ultimately discharging waste attached to the sewage outlet 311 toward the cleaning element 20. As the filter 41 moves toward the cleaning element 20, the elastic return member 60 applies an elastic force to the filter 41 away from the cleaning element 20, preventing it from getting too close to the cleaning element 20. After the waste is completely discharged, the cleaning element 20 stops rotating, at which point the elastic return member 60 applies a return force to the filter 41, causing it to return to its initial position. Illustratively, the elastic return member 60 in this embodiment may be a torsion spring, a spring, or an elastic rubber column.

[0065] Further, see Figure 8 、 Figures 11 to 14As shown, the resisting component 42 includes a resisting plate or a resisting block, which is rotatably arranged on the scraper assembly 30 through the second rotating shaft 70. The elastic element 43 includes a torsion spring 431, which is sleeved on the second rotating shaft 70, and one end of the torsion spring 431 is in contact with the resisting plate or the resisting block, and the other end of the torsion spring 431 is in contact with the scraper assembly 30.

[0066] Specifically, during operation, the abutting member 42 rotates counterclockwise around the second rotating shaft 70, and the end of the abutting member 42 near the filter 41 abuts against the filter 41 and pushes the filter 41 toward the cleaning member 20, thereby discharging garbage on the scraper assembly 30. Moreover, when the filter 41 approaches the cleaning member 20, the cleaning member 20 can also sweep away garbage remaining on the filter 41. During the counterclockwise rotation of the abutting member 42, the torsion spring 431 is deformed under the combined action of the abutting member 42 and the scraper assembly 30. After the garbage is cleaned, the cleaning member 20 stops rotating, at which point the torsion spring 431 gradually returns to its initial state. Under the action of the torsion spring 431, the abutting member 42 rotates clockwise around the second rotating shaft 70 and returns to its initial position.

[0067] From the above statements, it can be seen that the present application, by providing a cleaning device consisting of a main unit 10, a cleaning element 20, a scraper assembly 30, and a filter assembly 40, can at least solve the problem that the sewage outlet of the cleaning device is easily blocked by garbage. The present application uses two embodiments to respectively illustrate the situations where the filter assembly 40 and the scraper assembly 30 are fixedly connected and floatingly connected. Both connection methods can prevent the sewage outlet of the cleaning device from being blocked by garbage. The difference is that the fixed connection method of the filter assembly 40 and the scraper assembly 30 allows the cleaning element 20 to sweep away the garbage, while the floating connection method of the filter assembly 40 and the scraper assembly 30 allows not only the cleaning element 20 to sweep away the garbage, but also the garbage accumulated on the scraper assembly 30 can be spit out by the filter assembly 40. Compared with existing cleaning devices, the cleaning device of the present application can prevent the sewage outlet of the previous cleaning device from being easily blocked by garbage by providing the filter assembly 40, and has the advantages of simple structure and low manufacturing cost.

[0068] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0069] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0070] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
