Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more specifically, to a scraping mechanism and cleaning equipment. Background Technology

[0002] Robotic vacuum cleaners, mops, and floor scrubbers are types of smart home appliances that use artificial intelligence to automatically clean floors in a room. Currently, these cleaning devices typically have a suction port on their bottom casing, with a squeegee installed around the edge of the port. The squeegee conforms to the floor to gather debris towards the suction port and reduces air leakage during suction, ensuring the device can more easily draw debris into the port and thus improve its cleaning efficiency.

[0003] In existing technology, the scraper is designed as a sheet structure, with the side of the scraper away from the ground overlapping the base shell to fix it in place. However, when the scraper encounters an obstacle, the cleaning equipment is prone to vibration, the scraper is prone to loosening, affecting the adhesion between the scraper and the ground, and the scraper may even detach from the base shell, resulting in poor installation stability. Utility Model Content

[0004] The main purpose of this application is to provide a scraping mechanism and cleaning equipment to solve the problems of loosening and falling off of the scraping blades and poor installation stability in the prior art.

[0005] According to one aspect of this application, a scraping mechanism is provided, comprising:

[0006] A bottom shell assembly, the bottom shell assembly including a fixed bracket and a movable bracket, the fixed bracket having an opening, a first side of the movable bracket being rotatably mounted on the fixed bracket to drive a second side of the movable bracket opposite to the first side to swing along the height direction of the bottom shell assembly, and the movable bracket having a through hole corresponding to the opening;

[0007] A scraper assembly includes a scraping component and a holding component. Along the height direction of the bottom shell assembly, the scraping component includes an integrally formed buffer portion, a limiting portion, and a scraping portion. The top end of the buffer portion is connected to the fixed bracket, the limiting portion is connected to the bottom end of the buffer portion, and the limiting portion is installed on the second side of the movable bracket. The holding component presses against the limiting portion and is locked to the movable bracket by a locking component. The scraping portion is connected to the side of the limiting portion away from the buffer portion and extends a predetermined length toward the bottom of the movable bracket.

[0008] Furthermore, the limiting part is covered and installed on the movable bracket, and the pressing member is pressed on the side of the limiting part away from the movable bracket.

[0009] Furthermore, the scraping component includes a rubber component, a silicone component, or an elastic plastic component.

[0010] Furthermore, the limiting part includes a through groove extending along a first direction, a first snap-fit ​​part is provided on the inner wall surface of the through groove, and a second snap-fit ​​part is provided on the movable bracket to cooperate with the first snap-fit ​​part.

[0011] Furthermore, the buffer section includes:

[0012] A connecting segment, the connecting segment being connected to the fixed bracket;

[0013] An elastic segment is provided, which connects the connecting segment and the limiting portion.

[0014] Furthermore, the connecting segment is provided with a third snap-fit ​​part, and the fixed bracket is provided with a fourth snap-fit ​​part that cooperates with the third snap-fit ​​part.

[0015] Furthermore, the third latching part includes a first latching groove and a second latching groove, the first latching groove and the second latching groove are alternately arranged along a first direction, and the groove depth of the first latching groove is greater than the groove depth of the second latching groove, the first latching groove and / or the second latching groove are dovetail grooves, and the fourth latching part includes a first latching protrusion and a second latching protrusion, the first latching protrusion is adapted to the first latching groove, and the second latching protrusion is adapted to the second latching groove.

[0016] Furthermore, the scraper assembly extends along the length of the movable bracket and along the height of the bottom shell assembly. One end of the scraping portion extends a predetermined length away from the limiting portion to at least contact the cleaning surface. The buffer portion is connected to the fixed bracket to at least seal the gap between the movable bracket and the fixed bracket.

[0017] Furthermore, the pressing component includes a pressing plate having a connecting portion extending partially to the bottom of the movable bracket, the connecting portion being locked to the bottom of the movable bracket by the locking member.

[0018] On the other hand, this application also provides a cleaning device, which includes the aforementioned scraping mechanism.

[0019] In this application, the scraping part extends a predetermined length toward the bottom of the movable support, so that the side of the scraping part facing the bottom of the movable support can fit against the cleaning surface. During the movement of the cleaning equipment, the scraping part can gather the debris on the cleaning surface to the opening, and can also reduce air leakage when the cleaning equipment is vacuuming, ensuring that the cleaning equipment can more easily suck the debris into the opening, thereby improving the cleaning effect of the cleaning equipment.

[0020] The first side of the movable bracket is rotatably mounted on the fixed bracket, allowing the second side of the movable bracket to swing along the height direction of the fixed bracket. A limiting part is installed on the second side of the movable bracket, allowing the second side of the movable bracket to swing along the height direction of the bottom shell assembly under the action of the scraping part. When the scraping part encounters a large obstacle such as trash, or when the cleaning surface is uneven, the scraping part can transfer the external force applied by the higher part of the obstacle or cleaning surface to the second side of the movable bracket, causing the second side of the movable bracket to swing and rise along the height direction of the bottom shell assembly, thus lifting the scraping part upwards so that it can pass over the higher part of the obstacle or cleaning surface. Lifting the scraping part upwards over the higher part of the obstacle or cleaning surface reduces the friction between the scraping part and the obstacle or cleaning surface, reduces the vibration of the scraping part and the bumps of the cleaning equipment, and extends the service life of the cleaning equipment. Once the scraping part has passed over the obstacle or the higher part of the cleaning surface, the external force applied by the obstacle or the higher part of the cleaning surface is removed, and the scraping part and the second side of the movable bracket descend under the action of gravity, so that the scraping part returns to a state of mutual contact with the cleaning surface.

[0021] The integrated molding equipment for the buffer section, limiting section, and scraping section allows the scraping component to be injection molded in one step, strengthening its structural strength and reducing the risk of stress concentration and breakage. Only one mold is needed for scraping component production, reducing manufacturing costs and simplifying installation, thus improving assembly and disassembly efficiency. Furthermore, the second side of the movable support is raised under the action of the scraping section, and the buffer section is deformed by compression. This deformation absorbs impact, reducing vibration between the scraping section and the cleaning equipment, ensuring good stability. The limiting section increases the contact area between the scraping component and the movable support by covering the second side, and simultaneously locks the scraping component onto the movable support using pressing and locking components, effectively restricting movement and ensuring that the scraping component will not detach from the movable support even under significant vibration, thus improving its stability.

[0022] The buffer section also provides a certain sealing effect, sealing the space between the movable and fixed supports to effectively prevent garbage and sewage from entering the housing assembly. The limiting section is installed on the second side of the movable support, and the holding component presses against the limiting section and is locked to the movable support by the locking member. This increases the contact area between the scraper and the second side of the movable support, reducing the risk of the scraper loosening or falling off. Simultaneously, the limiting section on the second side of the movable support also disperses the lateral force on the scraper, providing stability. The holding component, pressed against the limiting section and fixed to the movable support by the locking member, further restricts the displacement of the scraper, improving its stability and extending its service life.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0037] like Figures 1 to 8 As shown, this application provides a scraping mechanism. The scraping mechanism includes a base assembly 10 and a scraper assembly 20. The base assembly 10 includes a fixed bracket 11 and a movable bracket 12. An opening is provided on the base assembly 10. A first side 121 of the movable bracket 12 is rotatably mounted on the base assembly 10 to drive a second side 122 of the movable bracket 12 opposite to the first side 121 along the height direction of the base assembly 10 (e.g., ...). Figure 1 The scraper assembly 20 swings in the direction indicated by the middle arrow X, and the movable bracket 12 is provided with a through hole 123 corresponding to the opening. The scraper assembly 20 includes a scraping member 21 and a holding member 22. The scraping member 21 covers at least the second side 122 of the movable bracket 12 and extends a predetermined length toward the bottom of the movable bracket 12. The holding member 22 presses against at least the portion of the scraping member 21 that covers the movable bracket 12 and is locked to the movable bracket 12 by the locking member 23.

[0038] In this embodiment, the bottom shell assembly 10 has an opening, and both the fixed bracket 11 and the movable bracket 12 are installed at the opening. The through hole 123 on the movable bracket 12 is positioned opposite to the opening along the height direction of the bottom shell assembly 10. A roller brush is installed on the fixed bracket 11, and the roller brush can rotate relative to the fixed bracket 11. The roller brush can gather debris on the cleaning surface to the opening. The scraper 21 extends a predetermined length toward the bottom of the movable bracket 12, so that the side of the scraper 21 facing the bottom of the movable bracket 12 can fit against the cleaning surface. During the movement of the cleaning equipment, the scraper 21 can gather debris on the cleaning surface to the opening, and can also reduce air leakage when the cleaning equipment is vacuuming, ensuring that the cleaning equipment can more easily suck debris into the opening, thereby improving the cleaning effect of the cleaning equipment.

[0039] The first side 121 of the movable support 12 is rotatably mounted on the base assembly 10, allowing the second side 122 of the movable support 12 to swing along the height direction of the base assembly 10. The scraper 21 is at least covered and mounted on the second side 122 of the movable support 12, allowing the second side 122 of the movable support 12 to swing along the height direction of the base assembly 10 under the action of the scraper 21. When the scraper 21 encounters a large obstacle such as trash, or when the cleaning surface is uneven, the scraper 21 can transmit the external force applied to the higher part of the obstacle or cleaning surface to the second side 122 of the movable support 12. This causes the second side 122 of the movable support 12 to swing and rise along the height direction of the base assembly 10, lifting the scraper 21 upwards so that it can pass over the higher part of the obstacle or cleaning surface. Lifting the scraper 21 upwards over the higher part of the obstacle or cleaning surface reduces the friction between the scraper and the obstacle or cleaning surface, reduces scraper vibration and equipment jolting, and extends the service life of the cleaning equipment. After the scraper 21 passes over the obstacle or the higher part of the clean surface, the external force applied by the obstacle or the higher part of the clean surface is removed, and the scraper 21 and the second side 122 of the movable bracket 12 descend under the action of gravity, so that the scraper 21 returns to the state of being in contact with the clean surface.

[0040] The scraper 21 is at least mounted on the second side 122 of the movable bracket 12. The holding member 22 presses against the portion of the scraper 21 that is mounted on the movable bracket 12 and is locked to the movable bracket 12 by the locking member 23. This increases the contact area between the scraper 21 and the second side 122 of the movable bracket 12, and the physical covering reduces the risk of the scraper 21 loosening or falling off. Simultaneously, the fact that the scraper 21 is at least mounted on the second side 122 of the movable bracket 12 can also disperse the lateral force on the scraper 21, providing stability. The holding member 22 presses against the portion of the scraper 21 that is mounted on the movable bracket 12 and is fixed to the movable bracket 12 by the locking member 23, further restricting the displacement of the scraper 21, improving its stability, and extending its service life.

[0041] like Figure 2 As shown, in one embodiment, along the height direction of the bottom shell assembly 10, the scraper 21 includes a buffer portion 211, a limiting portion 212, and a scraping portion 213. The top end of the buffer portion 211 is connected to the fixed bracket 11. The limiting portion 212 is connected to the bottom end of the buffer portion 211. The scraper 21 is mounted on the movable bracket 12 by covering the limiting portion 212. The holding member 22 is pressed against the side of the limiting portion 212 away from the movable bracket 12 and locked to the movable bracket 12 by the locking member 23. The scraping portion 213 is connected to the side of the limiting portion 212 away from the buffer portion 211 and extends a predetermined length toward the bottom of the movable bracket 12. When the scraping portion 213 encounters an obstacle on the side toward the bottom of the movable bracket 12, the scraping portion 213 is lifted by the debris, and the second side 122 of the movable bracket 12 is raised under the action of the scraping portion 213, causing the buffer portion 211 to be squeezed and deformed. The buffer section 211 absorbs impact force through deformation, reducing the vibration of the scraping section 213 and the cleaning equipment, and ensuring good stability of the scraping component 21. The limiting section 212 increases the contact area between the scraping component 21 and the movable support 12 by covering the second side 122 of the movable support 12. At the same time, the pressing component 22 and the locking component 23 lock the scraping component 21 onto the movable support 12, effectively restricting the movement of the scraping component 21 and ensuring that the scraping component 21 will not fall off the movable support 12 even under large vibrations, thus improving the stability of the scraping component 21. In addition, since the movable support 12 can move relative to the fixed support 11, there is a certain space between the movable support 12 and the fixed support 11 to meet the movement needs of the movable support 12. However, the space between the movable bracket 12 and the fixed bracket 11 will affect the sealing performance of the housing assembly. In this embodiment, the buffer part 211 also has a certain sealing effect. The buffer part 211 is disposed between the fixed bracket 11 and the movable bracket 12, sealing the space between the movable bracket 12 and the fixed bracket 11, effectively preventing garbage, sewage and other substances from entering the interior of the housing assembly.

[0042] The limiting part 212 is provided with a through groove 2121. The limiting part 212 is installed on the movable bracket 12 in such a way that the inner wall surface of the through groove 2121 is in contact with at least three surfaces of the second side 122 of the movable bracket 12. For example, the inner wall surface of the through groove 2121 is in close contact with the side of the second side 122 of the movable bracket 12 away from the through hole 123. Specifically, the inner wall surface of the through groove 2121 at least surrounds the side wall, upper wall surface, and lower wall surface of the second side 122 of the movable bracket 12 away from the through hole 123.

[0043] like Figure 3 As shown, in one embodiment, the buffer portion 211, the limiting portion 212, and the scraping portion 213 are integrally formed. The buffer portion 211, the limiting portion 212, and the scraping portion 213 can be injection molded in one step, which strengthens the structural strength of the scraping component 21 and reduces the risk of stress concentration and breakage. Only one mold is needed in the production of the scraping component 21, reducing its manufacturing cost and simplifying the installation operation, thus improving the efficiency of assembly and disassembly.

[0044] In one embodiment, the scraper 21 includes a rubber component. In another embodiment, the scraper 21 includes a silicone component. In yet another embodiment, the scraper 21 includes an elastic plastic component. Rubber, silicone, and elastic plastic components all possess good deformation capabilities. When the scraper 21 encounters an obstacle, it can deform to overcome the obstacle, effectively reducing vibration of the cleaning equipment and improving its stability. To ensure that the scraper 213 can adhere to the cleaning component to collect debris and reduce air leakage during vacuuming, this embodiment may set the hardness of the scraper 213 to be greater than the hardness of the buffer 211. It is understood that the above embodiments can be implemented individually or simultaneously.

[0045] like Figures 4 to 5 As shown, in one embodiment, the limiting portion 212 includes a first direction (e.g., Figure 1A through groove 2121 extends in the direction indicated by the middle arrow Y. A first engaging portion 2122 is provided on the inner wall of the through groove 2121, and a second engaging portion 2123 is provided on the movable bracket 12 to cooperate with the first engaging portion 2122. The inner wall of the through groove 2121 can cover the outer wall of the second side 122 of the movable bracket 12, allowing the scraper 21 to be initially positioned, reducing the difficulty of alignment during installation. The cooperation between the first engaging portion 2122 and the second engaging portion 2123 allows the scraper 21 to be installed on the movable bracket 12 more quickly, improving the assembly efficiency of the scraper 21. The first engaging portion 2122 and the second engaging portion 2123 can mechanically restrict the relative displacement between the scraper 21 and the movable bracket 12, especially when the cleaning equipment is bumpy or the scraper is under stress, effectively preventing the scraper 21 from detaching from the bracket and improving the stability of the scraper 21.

[0046] Specifically, one of the first latching portion 2122 and the second latching portion 2123 includes a limiting groove, and the other includes a limiting block adapted to the limiting groove. The length of the limiting groove extends along a first direction. During the assembly of the cleaning mechanism, the through groove 2121 of the cleaning component 21 is first installed over the second side 122 of the movable bracket 12, and the first latching portion 2122 is adapted to the second latching portion 2123. Then, the pressing member 22 is pressed onto the side of the limiting portion 212 away from the movable bracket 12. Then, the locking member 23 is connected between the pressing member 22 and the movable bracket 12 to lock the limiting portion 212 in the movable bracket. Finally, the buffer portion 211 is connected to the fixed bracket 11.

[0047] In one embodiment, the buffer section 211 includes a connecting section 2111 and an elastic section 2112. The connecting section 2111 is connected to the fixed bracket 11. The elastic section 2112 is connected between the connecting section 2111 and the limiting section 212. The elastic section 2112 can deform when the scraper 21 contacts an obstacle, reducing the vibration of the cleaning equipment body. When the movable bracket 12 swings with the height of the ground, the deformation capability of the elastic section 2112 allows the limiting section 212 and the scraper 213 to maintain a relatively stable ground contact angle, avoiding the scraper 213 from being suspended in the air or excessively pressing the ground due to excessive swing amplitude of the bracket, thus improving the uniformity of cleaning.

[0048] In one embodiment, the connecting segment 2111 is provided with a third snap-fit ​​portion, and the fixed bracket 11 is provided with a fourth snap-fit ​​portion that mates with the third snap-fit ​​portion. The engagement of the third snap-fit ​​portion of the connecting segment 2111 and the fourth snap-fit ​​portion of the fixed bracket 11 improves the ease of installation and structural stability of the scraping mechanism. The third and fourth snap-fit ​​portions enable quick positioning and tool-free installation, and the mechanical engagement securely locks the buffer portion 211 to the fixed bracket 11, preventing the buffer portion 211 from loosening or falling off due to vibrations during cleaning equipment operation or stress on the scraping portion 213. Simultaneously, the connecting segment 2111 is easy to disassemble and replace, reducing maintenance costs and minimizing space occupation caused by complex connectors, resulting in a more compact scraping mechanism structure that adapts to the internal layout of various cleaning equipment.

[0049] like Figures 6 to 7 As shown, the third engaging portion includes a first slot 2113 and a second slot 2114. The first slot 2113 and the second slot 2114 are alternately arranged along a first direction, and the depth of the first slot 2113 is greater than the depth of the second slot 2114. The first slot 2113 and / or the second slot 2114 are dovetail grooves. The fourth engaging portion includes a first protrusion 111 and a second protrusion 112. The first protrusion 111 is adapted to the first slot 2113, and the second protrusion 112 is adapted to the second slot 2114. The third engaging portion uses alternating first slots 2113 and second slots 2114 with different depths, respectively paired with adapted first protrusions 111 and second protrusions 112, to enhance connection performance from multiple dimensions. The different groove depths achieve stepped limiting; the first slot 2113 is used to bear the load in the main force direction, and the second slot 2114 assists in positioning. Together, they disperse stress and prevent overload of a single part. Meanwhile, the wedge-shaped structure of the dovetail groove provides a larger contact area and friction, forming a "barbed" locking effect. Even if the cleaning equipment vibrates violently or the scraper 21 is subjected to strong external impact, it can effectively prevent the buffer part 211 from coming off. The alternating arrangement of the first slot 2113 and the second slot 2114 also ensures the accuracy and uniqueness of the installation, avoiding assembly failure due to incorrect orientation. At the same time, disassembly can be performed step by step, simplifying the maintenance process, reducing the risk of accidental disassembly, and combining reliability and ease of use.

[0050] Furthermore, the elastic segment 2112 has a sheet-like structure. The maximum thickness of the elastic segment 2112 is H, where 0.3mm ≤ H ≤ 0.4mm. For example, the maximum thickness H of the elastic segment 2112 can be set to 0.3mm, 0.32mm, 0.34mm, 0.35mm, 0.36mm, 0.38mm, 0.4mm, etc. The elastic segment 2112 adopts a sheet-like structure with a thickness of 0.3mm-0.4mm, achieving a balance between elastic performance and structural strength. This thickness range ensures that the elastic segment 2112 has moderate flexibility, which can quickly deform elastically when the cleaning equipment encounters obstacles, effectively absorbing impact force and reducing the vibration and noise of the cleaning equipment, while effectively preventing insufficient strength and easy breakage due to being too thin, or affecting the elastic buffering effect due to being too thick. Meanwhile, the sheet-like structure makes the elastic section 2112 occupy less space, which fits the trend of lightweight and thin design of cleaning equipment. It is also easy to manufacture in one piece, reducing production costs. It can also ensure that when the movable support 12 swings, the limiting part 212 and the scraping part 213 can flexibly adjust their posture to maintain the adhesion to the ground and ensure cleaning efficiency and effect.

[0051] If H < 0.3 mm, the structural strength of the elastic segment 2112 will be insufficient. The segment is prone to fatigue fracture due to frequent elastic deformation. An excessively thin elastic segment 2112 may break quickly, shortening the service life of the buffer section 211. Furthermore, insufficient thickness of the elastic segment 2112 will reduce the material's energy storage capacity, resulting in inadequate impact absorption, greater vibration of the cleaning equipment, and affecting cleaning stability. If H > 0.4 mm, the elastic buffering capacity of the elastic segment 2112 will decrease. Excessive thickness increases material rigidity and reduces flexibility, making it difficult for the elastic segment 2112 to deform quickly when encountering obstacles. Impact cannot be effectively absorbed, potentially causing significant vibration of the cleaning equipment.

[0052] The scraper assembly 20 extends along the length of the movable bracket 12 and along the height of the base assembly 10. One end of the scraping part 213 extends a predetermined length away from the limiting part 212 to at least contact the cleaning surface. The buffer part 211 is connected to the fixed bracket 11 to at least seal the gap between the movable bracket 12 and the fixed bracket 11. The scraper assembly 20 extends along the length of the movable bracket 12, ensuring that the scraping part 213 has a large contact area with the cleaning surface. The scraping part 213 can more quickly gather the debris on the ground, providing cleaning efficiency. The holding member 22 also extends along the length of the movable bracket 12, so that the holding member 22 has a large contact area with the scraping part 21. The holding member can more stably press down on the scraping part 21 and reduce the stress concentration phenomenon of the scraping part 213, ensuring that the scraping part 213 can be stably installed on the movable bracket. The buffer part 211 is connected to the fixed bracket 11, so that even if the buffer part 211 is deformed, it can still seal the gap between the movable bracket 12 and the fixed bracket 11, effectively preventing garbage, sewage and other things from entering the interior of the housing assembly.

[0053] In one embodiment, the pressing member 22 includes a pressing plate 221. The pressing plate 221 has a connecting portion 222 that partially extends to the bottom of the movable bracket 12, and the connecting portion 222 is locked to the bottom of the movable bracket 12 by a locking member 23. The locking of the connecting portion 222 to the bottom of the movable bracket 12 by the locking member 23 ensures that the scraper 21 can be stably locked onto the movable bracket 12, and also facilitates the removal and installation of the scraper 21 from the bottom of the bottom housing assembly 10.

[0054] Specifically, in this embodiment, the locking member 23 is a screw, which passes through the connecting part 222 and the scraper 21 and is fixed to the movable bracket 12. The locking member can be a screw, a locking pin, or a latch, etc., and is not limited to these.

[0055] On the other hand, this application also provides a cleaning device that includes the aforementioned scraping mechanism. Therefore, this cleaning device incorporates all the technical effects of the aforementioned scraping mechanism. Since the technical effects of the scraping mechanism have already been described in detail above, they will not be repeated here.

[0056] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0057] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.
