Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0043] In order to solve the problem that the sewage outlet of the scraper of the cleaning device is easily blocked by garbage, a cleaning device is provided according to an embodiment of the present invention. 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 member 20 is rotatably disposed at the bottom of the main unit 10. The scraper assembly 30 is disposed at the bottom of the main unit 10 and located at the side of the cleaning member 20 to at least scrape off the garbage attached to the cleaning member 20. The scraper assembly 30 is provided with a sewage outlet 311. The filter assembly 40 is disposed at the sewage outlet 311 and covers the sewage outlet 311.

[0046] In the present application, a filter assembly 40 covering the sewage outlet 311 is provided at the sewage outlet 311 of the scraper assembly 30, so that 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. In actual operation, the host 10 can be moved. During the movement of the host 10, the cleaning member 20 can remove the garbage on the surface (such as the ground or the countertop) in contact with the cleaning member 20 by rotating. It can be understood that the garbage in this embodiment includes at least one of hair, dust, debris, sewage, etc. 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. Then, the garbage can flow into the sewage collection box of the cleaning device through the sewage outlet 311. At this time, since the sewage outlet 311 is covered with the filter assembly 40, the filter assembly 40 can filter the garbage scraped by the scraper assembly 30, thereby preventing large garbage from being blocked at the sewage outlet 311, so as not to affect the normal operation of the cleaning device.

[0047] That is to say, compared with the existing cleaning devices, 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 the 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 disposed 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 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 (such as Figure 1 , Figures 7 to 14 As shown). It is understandable that the floating arrangement described in the present application can be a rotation, a translation, or a combination of rotation and translation, etc. 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 3The cleaning member 20 can not only clean, but also remove the garbage and sewage attached to the side of the cleaning member 20 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 filter assembly 40 and the scraper assembly 30 are connected in a floating manner, such as Fig.12 As shown, the filter assembly 40 can be connected to the scraper assembly 30 by sliding, or by rotation, or by a combination of sliding connection and rolling connection. Figure 3 The cleaning member 20 can rotate in the direction indicated by b in the figure, and the garbage attached to the side of the cleaning member 20 can be scraped off by the scraper assembly 30 while performing the cleaning task. The filter assembly 40 can filter the garbage generated during the cleaning process to prevent the garbage from blocking the sewage outlet 311. When the cleaning device completes the cleaning work, the cleaning member 20 can rotate in the clockwise direction (i.e., the predetermined direction mentioned above, i.e., Figure 3 The cleaning element 20 rotates in the clockwise direction (in the direction indicated by a in the figure), and the garbage accumulated at the sewage outlet 311 can be spit out by the filter component 40 in the direction close to the cleaning element 20. The cleaning element 20 can also further clean the garbage in the filter component 40 during the clockwise rotation to achieve the purpose of cleaning the garbage in the filter component 40 and the scraper component 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 arranged at the bottom of the main unit 10, the scraper assembly 30 can be rotated and arranged at the bottom of the main unit 10, or both the filter assembly 40 and the scraper assembly 30 can be rotated and arranged 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, and the first embodiment shows a situation 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, and 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 reach the sewage collection box (not shown in the figure) of the cleaning device, so that the sewage outlet 311 can be prevented 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 , and 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 torsion springs 51 at intervals on the first rotating shaft 50, so that one end of the force torsion spring 51 can be pressed against the filter assembly 40, and the other end of the force torsion spring 51 can be pressed against the main unit 10, and finally the scraper assembly 30 is fixedly connected to the filter assembly 40. In actual operation, the cleaning member 20 moves counterclockwise (i.e. Figure 3 The cleaning device 20 is rotated 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 the side of the cleaning member 20 more closely. 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. When the cleaning device completes the cleaning work, the cleaning member 20 can be rotated in the clockwise direction (i.e. 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. Figure 5), and along the length direction perpendicular to the filter screen 41 (i.e. 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, and such a configuration allows the filter screen 41 to better fit with the scraper assembly 30 in the first embodiment. In other embodiments of the present application, the structure of the filter screen 41 can be reasonably designed according to the structure of the scraper assembly 30, thereby solving the problem that the sewage outlet 311 of the cleaning device is 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 push-up component 42 and an elastic element 43. The filter screen 41 is movably arranged on the scraper assembly 30 and covers the sewage outlet 311. The push-up component 42 is rotatably arranged on the scraper assembly 30. The push-up component 42 has a push-up top 421 protruding from the scraper assembly 30. The elastic element 43 pushes between the push-up component 42 and the scraper assembly 30, thereby completing the floating setting of the filter assembly 40. When the cleaning member 20 rotates in a predetermined direction, the cleaning member 20 drives the scraper assembly 30 to rotate and makes the push-up top 421 push against the main body 10, the push-up component 42 rotates to push the filter screen 41 to spit out the garbage attached to the sewage outlet 311 toward the direction close to the cleaning member 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 the clockwise direction under the drive of the cleaning member 20. As the filter assembly 40 rotates, the top end 421 of the abutting member 42 can abut against the bottom of the main unit 10. At this time, under the joint action of the cleaning member 20 and the main unit 10, the abutting member 42 rotates counterclockwise relative to the scraper assembly 30, and the other end of the abutting member 42 opposite to the top end 421 is in contact with the filter 41. When the abutting member 42 rotates counterclockwise, it can push the filter 41 to move toward the cleaning member 20, and finally spit out the garbage attached to the sewage outlet 311 toward the cleaning member 20. After the garbage is spit out, the cleaning member 20 stops rotating. At this time, under the action of the elastic element 43, the abutting member 42 can return to the position when it is in the static state.

[0057] Further, see Figures 7 to 10 As shown, the filter screen 41 includes a mesh body 411, a stop segment 412 and a connecting segment 413. A limiting hole 312 is provided on the scraper assembly 30. The connecting segment 413 is passed through the limiting hole 312 and can move in the limiting hole 312. The mesh body 411 is connected to a first end of the connecting segment 413. The stop segment 412 is located at a second end of the connecting segment 413 opposite to the first end. The mesh body 411 and the stop segment 412 limit the connecting segment 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 net 41 on the scraper assembly 30 to prevent it from falling. At the same time, the stop section 412 can also prevent the filter net 41 from tilting up during the movement. If the stop section 412 is not set, when the supporting component 42 pushes the filter net 41 to move, it is easy to cause the mesh body 411 and the sewage outlet 311 to be loosely fitted. At this time, garbage is easy to fall into the sewage outlet 311 from the gap between the mesh body 411 and the sewage outlet 311, and the sewage outlet 311 is easy to be blocked. Therefore, the stop section 412 is set on the filter net 41. In addition, the limiting hole 312 on the scraper assembly 30 can also prevent the mesh 411 from not fitting tightly with the sewage outlet 311 during the movement of the filter 41. The structure of the stopper section 412 can be configured to fit with the limiting hole 312, so that when the filter 41 moves, the mesh 411 can fit with the sewage outlet 311 at any time. In addition, the limiting hole 312 can also limit the movement of the filter 41 to prevent the filter 41 from being unable to reset due to excessive movement of the filter 41.

[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 torsion springs 51 are arranged at intervals on the first rotating shaft 50. One end of the force torsion spring 51 can be pressed against the connecting plate 32, and the other end of the force torsion spring 51 can be pressed against the main machine 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 machine 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 separately provided 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 segment 412 allows the filter screen 41 to be floatingly connected to the scraper body 31. With this arrangement, when the supporting component 42 rotates in a counterclockwise direction, the filter screen 41 can be pushed toward the direction close to the cleaning member 20, and finally the garbage attached to the sewage outlet 311 is spit out in the direction close to the cleaning member 20.

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

[0062] Specifically, the length direction of the stop section 412 is Fig. 9 In the direction indicated by y, the connecting segments 413 may include two, three or more than three, and correspondingly, the limiting holes 312 may also include two, three or more than three. In the second embodiment of the present application, the connection segments 413 and the limiting holes 312 each include two. 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 Fig.10), and the stopper section 412 is located at the end of the connecting section 413 away from the mesh body 411. In the present application, the stopper sections 412 may be interconnected or not. The second embodiment of the present application shows that the stopper sections 412 are interconnected, and the interconnection between the stopper sections 412 also has the advantage of making the structure of the filter screen 41 more stable. In addition, the structural design in which the connecting section 413 is penetrated through the limiting hole 312 and the stopper section 412 and the mesh body 411 are respectively located at the two ends of the connecting section 413 can ensure that the filter screen 41 is not easy to fall off the scraper body 31 when moving.

[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 the filter assembly 40 rotate in the clockwise direction under the drive of the cleaning member 20. As the filter assembly 40 rotates, the abutting top 421 of the abutting member 42 can abut against the bottom of the main unit 10. At this time, under the joint action of the cleaning member 20 and the main unit 10, the abutting member 42 rotates counterclockwise relative to the scraper assembly 30, so that the filter 41 can be pushed toward the direction close to the cleaning member 20, and finally the garbage attached to the sewage outlet 311 is spit out in the direction close to the cleaning member 20. In the process of the filter 41 moving toward the direction close to the cleaning member 20, the elastic reset member 60 can apply elastic force to the filter 41 in the direction away from the cleaning member 20 to prevent the filter 41 from being too close to the cleaning member 20. After the garbage is spit out, the cleaning member 20 stops rotating. At this time, the elastic reset member 60 can apply a reset elastic force to the filter 41, and the filter 41 can return to its initial position under the action of the reset elastic force. Exemplarily, the elastic reset 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 disposed on the scraper assembly 30 through the second rotating shaft 70, and 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 actual operation, the abutting component 42 rotates counterclockwise around the second rotating shaft 70, and the end of the abutting component 42 close to the filter screen 41 can abut against the filter screen 41 and push the filter screen 41 to move toward the cleaning member 20, so that the garbage on the scraper assembly 30 can be spit out, and when the filter screen 41 is close to the cleaning member 20, the cleaning member 20 can also sweep away the garbage remaining on the filter screen 41. During the counterclockwise rotation of the abutting component 42, the torsion spring 431 is deformed under the joint action of the abutting component 42 and the scraper assembly 30. After the garbage is cleaned, the cleaning member 20 stops rotating. At this time, the torsion spring 431 gradually returns to its initial state, and the abutting component 42 rotates clockwise around the second rotating shaft 70 under the action of the torsion spring 431 and returns to its initial position.

[0067] It can be known from the above statements that: the present application can at least solve the problem that the sewage outlet of the cleaning device is easily blocked by garbage by setting a cleaning device composed of a main unit 10, a cleaning member 20, a scraper assembly 30 and a filter assembly 40. The present application shows the situation that the filter assembly 40 and the scraper assembly 30 are fixedly connected and floatingly connected through two embodiments, and both connection methods can prevent the sewage outlet of the cleaning device from being blocked by garbage. The difference is that the method in which the filter assembly 40 and the scraper assembly 30 are fixedly connected can use the cleaning member 20 to sweep away the garbage, while the method in which the filter assembly 40 and the scraper assembly 30 are floatingly connected can not only use the cleaning member 20 to sweep away the garbage, but also use the filter assembly 40 to spit out the garbage accumulated on the scraper assembly 30. Compared with the existing cleaning device, the cleaning device of the present application can prevent the sewage outlet of the previous cleaning device from being easily blocked by garbage by setting 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 here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. 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 figure. For example, if the device in the accompanying 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 terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0070] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
