Abstract

The present invention relates to a scraper bar, a roller brush cover assembly, a roller brush mechanism, and a sweeping robot. The scraper bar includes a connecting portion, a scraper body, and an anti-reflection portion. The scraper body is connected to the connecting portion and extends along a first direction. Along a second direction perpendicular to the first direction, the scraper body has an upper surface and a lower surface relative to each other. The anti-reflection portion is protrudingly arranged on the lower surface of the scraper body. The anti-reflection portion has a working surface facing away from the lower surface, and the working surface is constructed as a nonlinear strip-shaped plane. In this way, the anti-reflection portion is added to the lower surface of the scraper body facing the ground, and the working surface of the anti-reflection portion in contact with the ground is designed as a nonlinear strip-shaped plane, so that when the anti-reflection portion contacts the ground, the working surface is flat and closely adheres to the ground to collect garbage. In addition, the working surface is wider in the direction of travel and has a greater friction force, which prevents the scraper bar from bending in the direction opposite to the direction of travel after being acted upon by external forces, thereby ensuring a cleaning effect.

Description

Technical Field

[0001] The present invention relates to the field of smart home appliance technology, in particular to a scraper bar, a roller brush cover assembly, a roller brush mechanism and a sweeping robot. Background Art

[0002] With the development of economy and the progress of society, people have higher and higher requirements for the quality of life. Therefore, some smart appliances that can free people's hands have emerged. Among them, sweeping robots, as a kind of smart home appliances, play an increasingly important role in people's daily lives.

[0003] A sweeping robot generally includes a dust collection system, a travel system, and a power supply system. The dust collection system is used to collect dust on the ground, the travel system is used to drive the sweeping robot to move, and the power supply system is used to provide energy for the dust collection system and the travel system. Generally, the dust collection system includes a roller brush mechanism, which includes a housing, a roller brush assembly, and a roller brush cover assembly. The roller brush cover assembly is coupled to the housing and encloses a roller brush chamber. The roller brush assembly is disposed within the roller brush chamber so that the roller brush assembly is installed and protected by the roller brush chamber. The roller brush cover assembly includes a roller brush cover, a scraper bar, and a pressure plate. The root of the scraper bar abuts between the pressure plate and the roller brush cover, and the scraper bar is assembled by squeezing the roller brush cover and the pressure plate. However, when the sweeping robot is moving, if the scraper bar touches large particles of garbage or the ground is uneven, the scraper bar tends to bend back in the direction opposite to the direction of travel, making it impossible to effectively collect garbage at the suction port, thus affecting cleaning efficiency. Summary of the Invention

[0004] Aiming at the problem that the scraper bar is easy to bend back, the present invention proposes a scraper bar, a roller brush cover assembly, a roller brush mechanism and a sweeping robot, which can achieve the technical effect of preventing the scraper bar from being bent back.

[0005] A scraper strip, comprising a connecting portion, a scraping body and an anti-reflection portion, wherein the scraping body is connected to the connecting portion and extends along a first direction;

[0006] In a second direction perpendicular to the first direction, the scraper body has an upper surface and a lower surface relative to each other, the anti-reflection portion is protruding from the lower surface of the scraper body, the anti-reflection portion has a working surface facing away from the lower surface, and the working surface is constructed as a nonlinear strip-shaped plane.

[0007] The scraper strip also includes an anti-reflection portion. The scraper body is connected to the connecting portion and extends along a first direction. Along a second direction perpendicular to the first direction, the scraper body has an upper surface and a lower surface relative to each other. The anti-reflection portion is protruding from the lower surface of the scraper body. The anti-reflection portion has a working surface facing away from the lower surface. The working surface is a plane that is constructed as a nonlinear strip. In this way, the anti-reflection portion is added to the lower surface of the scraper body facing the ground. The working surface of the anti-reflection portion that contacts the ground is designed as a nonlinear strip-shaped plane. When the anti-reflection portion contacts the ground, the working surface is flat and close to the ground to collect garbage. In addition, the working surface is wider in the direction of travel and has a greater friction force, which prevents the scraper strip from bending in the opposite direction of travel after being acted upon by external forces, thereby ensuring a cleaning effect.

[0008] In one embodiment, the anti-reflection portion is configured as a wavy strip.

[0009] In one embodiment, the anti-reflection portion is configured as a folded line strip.

[0031] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0032] In one embodiment of the present invention, a sweeping robot is provided, comprising a dust collection system, a walking system and a power supply system. The dust collection system is used to collect dust on the ground, the walking system is used to drive the sweeping robot to move, and the power supply system is used to provide working energy for the dust collection system and the walking system.

[0033] The dust collection system includes a roller brush mechanism, a dust box, an air duct and a fan. The dust box is connected to the outlet of the roller brush mechanism, and the air duct is connected between the dust box and the fan. When the roller brush mechanism is working, it picks up the dust on the ground, and then the suction force generated by the fan sucks the dust-mixed air into the interior of the sweeping robot. When the dust-mixed airflow passes through the dust box, the dust is filtered in the dust box, and the clean air is discharged from the air duct after passing through the fan, thus realizing the dust collection function.

[0034] See attached Figure 1 The roller brush mechanism 200 includes a housing (not shown), a roller brush assembly 210, and a roller brush cover assembly 100. The roller brush cover assembly 100 is mated with the housing to form a roller brush cavity, and the roller brush assembly 210 is disposed within the roller brush cavity. Specifically, the housing has an opening, and the roller brush assembly 210 is disposed within the housing through the opening. The roller brush cover assembly 100 is disposed within the opening and mated with the housing. In this way, a roller brush cavity is enclosed between the housing and the roller brush cover assembly 100, and the roller brush assembly 210 is assembled within the roller brush cavity.

[0035] See Figure 2-Figure 6 In some embodiments, the roller brush cover assembly 100 includes a scraper strip 10 and a pressure plate 30, wherein the scraper strip 10 includes a connecting portion 12 and a scraper body 14 connected to each other (see Figure 5 ), a slot 31 is provided on the pressing plate 30 (see Figure 6), the connecting portion 12 is at least partially inserted into the slot 31, and the scraper body 14 is constructed to protrude relative to the pressure plate 30. The scraper body 14 protrudes relative to the pressure plate 30. When the sweeping robot is in operation, the scraper body 14 maintains contact with the ground, gathering dust near the suction port 51 of the roller brush cover 50, thereby improving dust collection efficiency. Furthermore, a slot 31 is provided on the pressure plate 30, into which the connecting portion 12 of the scraper bar 10 is inserted, pre-installing the scraper bar 10 on the pressure plate 30. Subsequently, the pressure plate 30 is assembled to the roller brush cover 50 to complete the assembly of the scraper bar 10. When assembling the pressure plate 30 and roller brush cover 50, because the scraper bar 10 has been pre-installed into the slot 31, it will not shake or deviate, and can be easily squeezed between the pressure plate 30 and roller brush cover 50, improving the convenience of assembling the scraper bar 10.

[0036] Optionally, multiple protrusions are arranged at intervals on the inner wall of the slot 31 to increase the friction coefficient of the inner wall of the slot 31, thereby improving the reliability of the assembly between the connecting portion 12 of the scraper 10 and the slot 31, further preventing the scraper 10 from shaking relative to the pressure plate 30 and affecting the assembly efficiency, and further improving the convenience of assembly.

[0037] Furthermore, the roller brush cover assembly 100 further includes a roller brush cover 50, the pressing plate 30 being connected to the roller brush cover 50, and the connecting portion 12 at least partially abutting between the pressing plate 30 and the roller brush cover 50. A portion of the connecting portion 12 of the scraper strip 10 is disposed in the slot 31 to pre-position the scraper strip 10, and another portion of the connecting portion 12 of the scraper strip 10 abuts between the pressing plate 30 and the roller brush cover 50 to re-secure the scraper strip 10 and securely fix the scraper strip 10 to the roller brush cover 50.

[0038] Specifically, along the direction from the pressing plate 30 to the roller brush cover 50, the connecting portion 12 is at least partially limited and assembled in the slot 31. That is, in the vertical direction from the pressing plate 30 to the roller brush cover 50, the connecting portion 12 is limited by the slot 31, preventing the slot 31 from shaking in the vertical direction relative to the pressing plate 30, thereby maintaining the position of the scraper 10 relative to the pressing plate 30. Subsequently, the pressing plate 30 and the scraper 10 only need to be simultaneously abutted against the roller brush cover 50, which facilitates assembly.

[0039] In some embodiments, the connecting portion 12 includes an inserting section 121 and an abutting section 123. The inserting section 121 is inserted into the slot 31, and the abutting section 123 is connected between the inserting section 121 and the scraper body 14. The abutting section 123 abuts between the pressing plate 30 and the roller brush cover 50. That is, the connecting portion 12 includes two sections, the inserting section 121 is used to assemble with the slot 31, and the abutting section 123 is used to abut between the pressing plate 30 and the roller brush cover 50. In this way, the scraper strip 10 can be pre-installed on the pressing plate 30 through the inserting section 121, or it can be completely fixed between the pressing plate 30 and the roller brush cover 50 through the abutting section 123, so that the scraper strip 10 can be simply and reliably assembled on the roller brush cover 50 to collect garbage.

[0040] Furthermore, the pressing plate 30 includes a plate body 32 and a support portion 34. The plate body 32 is provided with a slot 31. The support portion 34 is connected to the side of the plate body 32 provided with the slot 31. The abutting section 123 abuts between the support portion 34 and the roller brush cover 50. The support portion 34 is provided on the pressing plate 30 to support the abutting section 123 so that the abutting section 123 is pressed against the roller brush cover 50 by the support portion 34. The slot 31 is provided on the side adjacent to the support portion 34 to facilitate the insertion section 121 into the slot 31 for pre-installation of the scraper strip 10.

[0041] Specifically, the support portion 34 includes a support bar 341, which is arranged on the side of the plate body 32 that is matched with the scraper strip 10, and extends along the longitudinal direction of the slot 31. At the same time, the height of the support bar 341 is lower than the height of the plate body 32, so that the support bar 341 and the plate body 32 are arranged in a stepped shape. At this time, a stepped groove 35 connected to the slot 31 is formed between the support bar 341 and the plate body 32. The side of the support bar 341 facing the stepped groove 35 at least partially abuts against the abutment section 123, so that the abutment section 123 is pressed into place through the side of the support bar 341 facing the stepped groove 35. In addition, the slot 31 is connected to the stepped groove 35, so that when the plug-in section 121 is inserted into the slot 31, the abutment section 123 connected to the plug-in section can fall into the stepped groove 35 and can be fixed by the support bar 341.

[0042] Optionally, the support portion 34 further includes a support rib 343 disposed on the surface of the support bar 341 facing the stepped groove 35. At least a portion of the abutment section 123 abuts against the support rib 343. Because the stepped groove 35 is recessed inward, the abutment section 123 needs to be correspondingly recessed when it abuts the support bar 341. To prevent the abutment section 123 from recessing too much, the support rib 343 is disposed within the stepped groove 35 to support the abutment section 123, preventing the abutment section 123 from recessing too much and making assembly inconvenient, thereby improving assembly convenience.

[0043] Specifically, the abutment section 123 includes a first sub-segment 125 and a second sub-segment 127 connected at an angle. The second sub-segment 127 is connected at an angle between the first sub-segment 125 and the connecting section 121. The support ribs 343 support the side of the second sub-segment 127 facing away from the roller brush cover 50, and the support bars 341 support the side of the first sub-segment 125 facing away from the roller brush cover 50. Thus, the inclined transition second sub-segment 127 is provided between the connecting section 121 and the first sub-segment 125 to connect the displaced connecting section 121 and the first sub-segment 125. The support ribs 343 also support the second sub-segment 127 to prevent deformation, thus securely fitting the abutment section 123 within the stepped groove 35.

[0044] In some embodiments, the scraper strip 10 further includes a stop portion 16, which is connected to the abutting section 123, and abuts against the side of the support portion 34 facing away from the plate body 32, so that the stop portion 16 and the support portion 34 are assembled in the direction of the plate body 32 pointing to the support portion 34, so as to locate the position where the scraper strip 10 is assembled on the pressure strip, so that the scraper strip 10 can be accurately assembled to the preset position of the pressure strip, which is convenient for subsequent installation.

[0045] See Figure 7-Figure 8 In some embodiments, the scraper strip 10 further includes an anti-rebound portion 18. The scraper body 14 is connected to the connecting portion 12 and extends along a first direction. Simultaneously, in a second direction perpendicular to the first direction, the scraper body 14 has an upper surface 141 and a lower surface 143 that face each other. The anti-rebound portion 18 protrudes from the lower surface 143 of the scraper body 14 and has a working surface 181 facing away from the lower surface 143. The working surface 181 is a flat surface configured as a nonlinear strip. Thus, the anti-rebound portion 18 is added to the lower surface 143 of the scraper body 14 that faces the ground. The working surface 181 of the anti-rebound portion 18 that contacts the ground is designed as a nonlinear strip. When the anti-rebound portion 18 contacts the ground, the working surface 181 forms a flat surface that adheres closely to the ground, collecting debris. Furthermore, the working surface 181 is relatively wide in the direction of travel, providing greater friction. This prevents the scraper strip 10 from bending in the opposite direction of travel when subjected to external forces, thereby ensuring effective cleaning.

[0046] Specifically in this embodiment, the anti-rebound portion 18 is constructed as a wavy strip with a wavy, strip-like working surface 181. It is understood that the anti-rebound portion 18 can also be constructed as a zigzag strip with a zigzag, strip-like working surface 181. In this way, the working surface 181 of the anti-rebound portion 18 is configured as a curved or bent surface in the direction of travel of the robot vacuum cleaner. This increases the width of the anti-rebound portion 18 in the direction of travel, thereby preventing the anti-rebound portion 18 from bending in the opposite direction of travel during the robot vacuum cleaner's movement.

[0047] Furthermore, along a third direction perpendicular to both the first and second directions, the anti-rebound portion 18 has opposing third and fourth surfaces 183 and 185. The third surface 183 intersects and connects with the upper surface 141 of the scraper body 14, while the fourth surface 185 intersects and connects with the lower surface 143 of the scraper body 14. This is equivalent to the anti-rebound portion 18 intersecting and connecting with the scraper body 14. The third surface 183 intersects and connects with the upper surface 141 of the scraper strip 10 to form a single unit, which can be used to push garbage toward the suction port 51. At the same time, the anti-rebound portion 18, intersecting and connecting with the scraper body 14, strengthens the overall strength of the scraper strip 10 and prevents the scraper body 14 from folding back. Specifically, in this embodiment, both the third and fourth surfaces 183 and 185 are wavy, forming a wavy, strip-shaped working surface 181 connecting the third and fourth surfaces 183 and 185. It is understandable that in some other embodiments, the third surface 183 and the fourth surface 185 may also be bent surfaces to form a bent strip-shaped working surface 181 connected between the third surface 183 and the fourth surface 185 .

[0048] Specifically in this embodiment, the anti-reflection portion 18 is provided at the end of the scraper 14 facing away from the connecting portion 12, that is, the anti-reflection portion 18 is connected to the free end of the scraper 14 in the moving direction to strengthen the free end of the scraper 14 and improve the anti-reflection effect.

[0049] Based on the same concept, one embodiment of the present invention provides a roller brush mechanism 200, comprising a housing, a roller brush assembly 210, and a roller brush cover assembly 100. The roller brush cover assembly 100 mates with the housing to enclose a roller brush cavity, and the roller brush assembly 210 is disposed within the roller brush cavity, so that the roller brush assembly 210 is installed and protected by the roller brush cavity. Specifically, the housing has an opening, and the roller brush assembly 210 is disposed within the housing through the opening. The roller brush cover assembly 100 covers the opening and mates with the housing. Thus, a roller brush cavity is enclosed between the housing and the roller brush cover assembly 100, and the roller brush assembly 210 is assembled within the roller brush cavity.

[0050] In some embodiments, the scraper strip 10 further includes an anti-rebound portion 18. The scraper body 14 is connected to the connecting portion 12 and extends along a first direction. Along a second direction perpendicular to the first direction, the scraper body 14 has an upper surface 141 and a lower surface 143 that oppose each other. The anti-rebound portion 18 protrudes from the lower surface 143 of the scraper body 14 and includes a working surface 181 facing away from the lower surface 143. The working surface 181 is a flat surface configured as a nonlinear strip. Thus, the anti-rebound portion 18 is added to the lower surface 143 of the scraper body 14 that faces the ground. The working surface 181 of the anti-rebound portion 18 that contacts the ground is designed as a nonlinear strip. When the anti-rebound portion 18 contacts the ground, the working surface 181 forms a flat surface that adheres to the ground, collecting debris. Furthermore, the working surface 181 is relatively wide in the direction of travel, providing greater friction. This prevents the scraper strip 10 from bending in the opposite direction of travel when subjected to external forces, thereby ensuring a cleaning effect.

[0051] Based on the same concept, an embodiment of the present invention provides a roller brush cover assembly 100. The roller brush cover assembly 100 includes a scraper bar 10, a pressure plate 30, and a roller brush cover 50. The scraper bar 10 is assembled between the pressure plate 30 and the roller brush cover 50, and includes an anti-reverse portion 18. The anti-reverse portion 18 prevents the scraper bar 10 from bending in the opposite direction of travel, thereby ensuring a cleaning effect.

[0052] Based on the same concept, in one embodiment of the present invention, a scraper strip 10 is provided. The scraper strip 10 includes an anti-reflection portion 18. The anti-reflection portion 18 prevents the scraper strip 10 from bending in the reverse direction of travel, thereby ensuring a cleaning effect.

[0053] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
