Description

A cleaning device Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a cleaning device. Background Art

[0002] Cleaning devices currently available on the market generally use single, double, or crawler-type roller brushes. All of these roller brushes leave water stains on the floor after cleaning. In particular, when the cleaning device reciprocates back and forth to clean the floor, a fixed scraper bar beneath the roller brush can scrape away any remaining water stains from the roller brush when the machine is moving forward. However, when the machine is moving backward, the fixed scraper bar is unable to scrape away any remaining water stains from the roller brush. This reciprocating motion makes it difficult to scrape away any remaining water stains from the floor. For example, Chinese patent publication number CN112568799A discloses a roller brush cover assembly, a roller brush mechanism, and a sweeping robot. The roller brush cover assembly includes a pressure plate, a roller brush cover, and a scraper bar. The pressure plate includes a plate body, and the roller brush cover includes a cover body. A buckle is provided on one of the plate body and the cover body, and a buckle is provided on the other of the plate body and the cover body. The buckle and the buckle engage with each other, and the scraper bar abuts between the roller brush cover and the pressure plate. It can be seen that the scraping bar of the roller brush cover assembly is fixedly arranged between the roller brush cover and the pressure plate. After the sweeping robot moves back and forth, there will be a problem that the water stains remaining on the ground from the roller brush cannot be scraped off, and the cleaning effect is poor.

[0003] Summary of the Invention

[0004] In response to the above technical problems existing in the prior art, the present invention provides a cleaning device, which can effectively clean water stains remaining on the ground through movable scraping bars and fixed scraping bars when the cleaning device moves in different directions, and has a better cleaning effect.

[0005] An embodiment of the present invention provides a cleaning device, comprising:

[0006] A roller brush assembly comprising at least one brush body;

[0007] a scraper bar assembly, comprising a movable scraper bar and a fixed scraper bar, one end of the fixed scraper bar being against the ground, the movable scraper bar and the fixed scraper bar being respectively arranged on opposite sides of the brush body, the movable scraper bar having a first position raised relative to the ground and a second position against the ground, the movable scraper bar being configured to be in the first position when the brush body moves in the direction of the movable scraper bar, and to be in the second position when the brush body moves in the direction of the fixed scraper bar;

[0008] An actuating assembly is configured to drive the movable scraper bar to move between the first and second positions. The actuating assembly and the movable scraper bar are located on opposite sides of the brush body. The movable scraper bar and the fixed scraper bar enable the cleaning device to effectively clean water stains remaining on the floor when the cleaning device moves in different directions, achieving a superior cleaning effect.

[0009] In some embodiments, the brush bodies are two, arranged side by side in a front-to-back arrangement, and the scraper bar assemblies are arranged in a one-to-one correspondence with the brush bodies. The two fixed scraper bars are arranged between the two brush bodies, and the two movable scraper bars are distributed on the sides of the two brush bodies that are separated from each other. In this way, the two brush bodies can clean the floor in coordination, and the two movable scraper bars can clean water stains left on the floor by the corresponding two brush bodies, thereby achieving the purpose of improving the cleaning effect.

[0010] In some embodiments, the actuating assembly includes a driving member and a transmission member, wherein the driving member is configured to drive the transmission member to move, and the transmission member is configured to drive the movable scraper strip to switch between the first position and the second position. The actuating assembly can drive the two movable scraper strips to switch between the first position and the second position, resulting in a compact and reasonable design.

[0011] In some embodiments, the transmission member rotates under the action of the driving member, and the transmission member is used to rotate to release or tighten the movable scraper, so that the movable scraper is in the second position when released, and the movable scraper is in the first position when tightened.

[0012] In some embodiments, the transmission member performs a swinging motion under the action of the driving member, and the transmission member is used to swing toward the movable scraper to make the movable scraper press against the ground, and swing away from the movable scraper to lift the movable scraper relative to the ground.

[0013] In some embodiments, both movable scraper strips are connected to the transmission member, which is used to rotationally or swingably drive one of the two movable scraper strips to the first position and the other to the second position. The transmission member can simultaneously drive the two movable scraper strips to move, which is a reasonable structural design and effectively reduces costs.

[0014] In some embodiments, the movable scraper bar is configured in an arc shape that matches the outer contour of the brush body. In this way, the movable scraper bar can be closer to the brush body when it moves toward the ground, making it easier to clean garbage and water stains remaining on the ground.

[0015] In some embodiments, a spacer cavity is formed between the movable scraper and the brush body, and the spacer cavity is arc-shaped. The above structure can ensure that the movable scraper maintains a relatively close relative position relationship with the brush body when switching between the first position and the second position, thereby further ensuring the cleaning effect.

[0016] In some embodiments, the transmission member includes a rotating body and a flexible body. The driving member is used to drive the rotating body to rotate. The flexible body is disposed around the rotating body and acts on the two movable scrapers to rotationally release one of the two movable scrapers and simultaneously tighten the other of the two movable scrapers. The rotating body and the flexible body can stably drive the two movable scrapers to move up or down, maintaining the stability of the movement of the movable scrapers.

[0017] In some embodiments, both of the movable scrapers are connected to the transmission member, and the transmission member includes a swing arm connected to the driving member, and the swing arm has a first swing end and a second swing end, and the first swing end and the second swing end are respectively pivotally connected to one of the movable scrapers, and the swing arm is used to swing one of the two movable scrapers against the ground and the other is lifted relative to the ground.

[0018] In some embodiments, the actuating assembly further comprises an elastic member configured to apply a force to the movable scraper bar to force it against the ground. The elastic member can force the movable scraper bar against the ground, maintaining a stable position against the ground and ensuring that water stains on the ground are completely removed.

[0019] In some embodiments, the cleaning device further includes a water pump and a dirt suction duct disposed between the two brush bodies. The water pump is configured to supply cleaning water to the two brush bodies, and the drive member and the water pump are located on opposite sides of the dirt suction duct. This structure balances gravity on both sides of the cleaning device, preventing one side from tilting, and ensuring effective cleaning.

[0020] In some embodiments, the cleaning device further includes a sensing element and a first control board. The sensing element is configured to detect the direction of rotation of the brush body. The first control board is electrically connected to the sensing element and the driving member, respectively, and is configured to receive the direction of rotation detected by the sensing element and send a control instruction to the driving member. The sensing element can stably detect the direction of rotation of the brush body, thereby precisely controlling the direction of rotation of the driving member based on the direction of the brush body, thereby precisely controlling the raising or lowering of the movable scraper bar.

[0021] In some embodiments, the cleaning device also includes a housing for installing the roller brush assembly and the scraper assembly, the housing includes an upper shell and a lower shell, the inner walls of the upper shell and the lower shell cooperate to form an arc-shaped cavity, and the arc-shaped movable scraper is arranged in the arc-shaped cavity.

[0022] Compared with the prior art, the beneficial effect of the embodiments of the present invention lies in that: by arranging the movable scraper and the fixed scraper of the scraper assembly on opposite sides of the brush body, and the movable scraper having a first position raised relative to the ground and a second position pressed against the ground, the brush body can move in the direction of the movable scraper and the fixed scraper respectively, so that water stains remaining on the ground can be effectively cleaned by one of the movable scraper and the fixed scraper, thereby achieving the purpose of cleaning the ground without leaving any water stains on the ground, and effectively improving the cleaning effect of the cleaning device. In addition, the structural layout of the above-mentioned actuating assembly and the movable scraper can fully utilize the space on both sides of the brush body, making the structural layout more compact and reasonable.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] An embodiment of the present invention provides a cleaning device 100. As shown in Figures 1 to 5, the cleaning device 100 includes a roller brush assembly, a scraper assembly 2, and an actuating assembly 3. The roller brush assembly includes at least one brush body 1. The scraper assembly 2 includes a movable scraper 201 and a fixed scraper 202. One end of the fixed scraper 202 is against the ground. The movable scraper 201 and the fixed scraper 202 are respectively arranged on opposite sides of the brush body 1. The movable scraper 201 has a first position raised relative to the ground and a second position against the ground. The movable scraper 201 is used to be in the first position when the brush body 1 moves in the direction of the movable scraper 201, and to be in the second position when the brush body 1 moves in the direction of the fixed scraper 202. The actuating assembly 3 is used to drive the movable scraper 201 to move between the first position and the second position. The actuating assembly 3 and the movable scraper 201 are distributed on opposite sides of the brush body 1.

[0034] The above-mentioned cleaning device 100 can be applied to a sweeping device. The sweeping device may include a body 200 connected to the cleaning device 100. The body 200 may include a handheld part. The handheld part may be provided with a suction box 9, a switch button, a suction motor, etc. to cooperate with the sweeping device to realize the garbage absorption function.

[0035] Optionally, the movable scraper bar 201 may include a hard scraper body and a flexible scraper body. The hard scraper body is farther away from the ground than the flexible scraper body. When the movable scraper bar 201 is in the second position, the flexible scraper body can maintain a close fit with the ground by deformation.

[0036] As shown in FIG3 and FIG4 , the movable scraper bar 201 and the fixed scraper bar 202 are respectively arranged on opposite sides of the brush body 1 , which can be understood as being respectively arranged on two sides in the radial direction of the brush body 1 , ie, on two sides in the moving direction of the roller brush.

[0037] As shown in Figures 3 and 4, the movement of the brush body 1 of the cleaning device 100 shown in Figure 3 toward the movable scraper bar 201 can be understood as forward movement, with the arrow shown in the figure indicating the direction of movement. The movement of the brush body 1 of the cleaning device 100 shown in Figure 3 toward the fixed scraper bar 202 can be understood as backward movement, with the arrow shown in the figure indicating the direction of movement. As shown in Figure 3, during forward movement, i.e., when the brush body 1 moves toward the movable scraper bar 201, the movable scraper bar 201 is in a first position raised relative to the ground. As shown in Figure 4, during backward movement, i.e., when the brush body 1 moves toward the fixed scraper bar 202, the movable scraper bar 201 is in a second position pressed against the ground.

[0038] The present invention provides a cleaning device 100 with a movable scraper bar 201 and a fixed scraper bar 202 disposed on opposite sides of the brush body 1, respectively. Furthermore, the movable scraper bar 201 has a first position in which it is raised relative to the ground and a second position in which it rests against the ground. This allows the brush body 1 to move in either the movable scraper bar 201 or the fixed scraper bar 202 direction, respectively, to effectively clean water stains remaining on the ground. This achieves the goal of cleaning the ground without leaving any water stains, effectively improving the cleaning effect of the cleaning device 100. Furthermore, the structural layout of the actuating assembly 3 and the movable scraper bar 201 fully utilizes the space on both sides of the brush body 1, making the structural layout more compact and reasonable.

[0039] In some embodiments, as shown in Figures 2 to 4 , there are two brush bodies 1, arranged side by side front and back, with scraper bars 2 corresponding to each brush body 1. Two fixed scraper bars 202 are positioned between the two brush bodies 1, and two movable scraper bars 201 are located on the sides of the two brush bodies 1 that are spaced apart. This allows the two brush bodies 1 to work together to clean the floor, while the two movable scraper bars 201 can clean water stains left on the floor by the corresponding two brush bodies 1, thereby improving the cleaning effect.

[0040] The two brush bodies 1 described above can be understood as a front brush body and a rear brush body. As shown in FIG3 , the brush body 1 on the left can be the front brush body, and the brush body 1 on the right can be the rear brush body. As shown in FIG3 , when a user uses the cleaning device 100 to move forward for cleaning, the movable scraper bar 201 corresponding to the front brush body can be in a first position raised relative to the ground, and the movable scraper bar 201 corresponding to the rear brush body can be in a second position pressed against the ground. As shown in FIG4 , when a user uses the cleaning device 100 to move backward for cleaning, the movable scraper bar 201 corresponding to the front brush body can be in a second position pressed against the ground, and the movable scraper bar 201 corresponding to the rear brush body can be in a first position raised relative to the ground. This ensures that the ground can be cleaned thoroughly during the reciprocating forward and backward cleaning, and no water stains remain on the ground, effectively improving the cleaning effect.

[0041] Optionally, the two movable scraper strips 201 may be provided independently, or may be driven by the same electric actuating component.

[0042] In some embodiments, as shown in FIG2 , the actuating assembly 3 includes a driving member 301 and a transmission member 302. The driving member 301 is configured to drive the transmission member 302 to move, and the transmission member 302 is configured to drive the movable scraper 201 to switch between the first position and the second position. The actuating assembly 3 can drive the two movable scraper strips 201 to switch between the first position and the second position, resulting in a compact and reasonable design.

[0043] The driving member 301 can be understood as a motor, and its output shaft can drive the transmission member 302 to rotate. The rotation of the transmission member 302 can release the movable scraper 201 to make it in the second position, and can also tighten the movable scraper 201 to make it in the first position.

[0044] Optionally, the driving member 301 may be placed vertically to fully utilize the internal space of the cleaning device 100 .

[0045] It is understandable that the movement performed by the transmission member 302 may be one of a rotational movement and a swinging movement.

[0046] In some embodiments, the transmission member 302 rotates under the action of the driving member 301, and the transmission member 302 is used to rotate to release or tighten the movable scraper 201, so that the movable scraper 201 is in the second position when released, and the movable scraper 201 is in the first position when tightened.

[0047] In some embodiments, the transmission member 302 swings under the action of the driving member 301, and the transmission member 302 is used to swing toward the movable scraper 201 so that the movable scraper 201 is against the ground, and to swing away from the movable scraper 201 so that the movable scraper 201 is lifted relative to the ground.

[0048] It is understandable that when there are two movable scraper strips 201, when the transmission member 302 swings toward one of the movable scraper strips 201, the movable scraper strip 201 will move toward the ground until it hits the ground, and the other movable scraper strip 201 will move away from the ground to be lifted relative to the ground.

[0049] In some embodiments, as shown in Figures 2 to 4, both movable scraper bars 201 are connected to a transmission member 302. The transmission member 302 is used to rotate or swingably drive one of the two movable scraper bars 201 to a first position and the other to a second position. The transmission member 302 can simultaneously drive the movement of both movable scraper bars 201, resulting in a reasonable structural design and effective cost reduction.

[0050] As shown in FIG3 , when the user uses the cleaning device 100 to clean forward, the transmission member 302 can be driven by the driving member 301 to tighten the movable scraping bar 201 corresponding to the front brush body, while simultaneously releasing the movable scraping bar 201 corresponding to the rear brush body. As shown in FIG4 , when the user uses the cleaning device 100 to clean backward, the transmission member 302 can be driven by the driving member 301 to tighten the movable scraping bar 201 corresponding to the rear brush body, while simultaneously releasing the movable scraping bar 201 corresponding to the front brush body.

[0051] Optionally, the two movable scraping strips 201 may be respectively disposed on opposite sides of the transmission member 302 .

[0052] In some embodiments, as shown in Figures 2 to 4, the movable scraper bar 201 is shaped as an arc that matches the outer contour of the brush body 1. In this way, the movable scraper bar 201 can be closer to the brush body 1 when it moves toward the ground, making it easier to clean the garbage and water stains remaining on the ground.

[0053] Optionally, the hard scraping body and the flexible scraping body of the movable scraping strip 201 can both be configured as arcs that match the outer contour of the brush body 1. In addition, the arcs corresponding to the shapes of the hard scraping body and the flexible scraping body can be smoothly connected.

[0054] In some embodiments, as shown in Figures 2 to 4 , a spacer cavity is formed between the movable scraper bar 201 and the brush body 1. The spacer cavity is arc-shaped. This structure ensures that the movable scraper bar 201 maintains a relatively close relative position to the brush body 1 when switching between the first position and the second position, thereby further ensuring a cleaning effect.

[0055] In some embodiments, as shown in FIG2 , the transmission member 302 includes a rotating body 303 and a flexible body 306. The driving member 301 is used to drive the rotating body 303 to rotate. The flexible body 306 is wound around the rotating body 303. The flexible body 306 acts on the two movable scraper strips 201 to rotationally release one of the two movable scraper strips 201 and simultaneously tighten the other of the two movable scraper strips 201. The rotating body 303 and the flexible body 306 can stably drive the two movable scraper strips 201 to move up or down, maintaining the stability of the movement of the movable scraper strips 201.

[0056] Optionally, the flexible body 306 is constructed as a rope, the middle portion of which is wound around the rotating body 303, and the two ends are respectively connected to the two movable scraping strips 201. The above structure occupies a small space and has a low structural design cost.

[0057] Optionally, the transmission member 302 may include a connecting member 304, which may be specifically hook-shaped and used to enable the flexible body 306 to be stably connected to the movable scraper strip 201. The connecting member 304 and the movable scraper strip 201 are provided in a one-to-one correspondence.

[0058] In some embodiments, as shown in Figures 6 and 7 , both movable scraper bars 201 are connected to a transmission member 302 . The transmission member 302 includes a swing arm 307 connected to the driving member 301 . The swing arm 307 has a first swing end and a second swing end, each pivotally connected to a movable scraper bar 201 . The swing arm 307 is used to swing one of the two movable scraper bars 201 against the ground, while the other is raised relative to the ground. The swing arm 307 can stably drive the two movable scraper bars 201 to alternately move up and down.

[0059] Optionally, as shown in FIG6 and FIG7 , the swing arm 307 may be V-shaped, with its two open ends forming a first swing end and a second swing end respectively.

[0060] Optionally, a connecting shaft 308 may be sleeved within the first swing end and the second swing end, respectively. The movable scraper bar 201 is connected to a pivot member 309, which has a slide groove. The connecting shaft 308 is inserted into the slide groove. The connecting shaft 308 and the pivot member 309 enable a pivotal connection between the swing arm 307 and the movable scraper bar 201. When the swing arm 307 swings under the drive member 301, the connecting shaft 308 slides within the slide groove, allowing the swing arm 307 to swing within a certain range relative to the movable scraper bar 201.

[0061] In some embodiments, as shown in FIG2 , the actuating assembly 3 further includes an elastic member 305 for applying a force to the movable scraper bar 201 to force it against the ground. The elastic member 305 can press the movable scraper bar 201 against the ground, maintaining a stable position against the ground and ensuring that water stains on the ground are completely removed.

[0062] Optionally, the movable scraper strip 201 may be provided with a groove corresponding to the elastic member 305 to save space volume and greatly reduce the front space of the brush body 1.

[0063] In some embodiments, as shown in FIG2 , the cleaning device 100 further includes a water pump 4 and a dirt suction duct 5 disposed between the two brush bodies 1. The water pump 4 is used to supply cleaning water to the two brush bodies 1. The driving member 301 and the water pump 4 are located on opposite sides of the dirt suction duct 5. This structure balances the gravity on both sides of the cleaning device 100, preventing one side from tilting, and ensuring a good cleaning effect.

[0064] Optionally, the water outlet of the water pump 4 may be connected to a tee for dividing the water pumped in by the water pump 4 into two and injecting them into the water channels of the two brush bodies 1 respectively, so as to stably supply water to the brush bodies 1 .

[0065] In some embodiments, as shown in FIG2 , the cleaning device 100 further includes a sensing element 6 and a first control board 7. The sensing element 6 is used to detect the direction of the brush body 1. The first control board 7 is electrically connected to the sensing element 6 and the driving member 301, respectively. The first control board 7 is used to receive the direction information detected by the sensing element 6 and send control instructions to the driving member 301. The sensing element 6 can stably detect the direction of the brush body 1, so that the direction of the driving member 301 can be accurately controlled based on the direction of the brush body 1, thereby accurately controlling the raising or lowering of the movable scraper 201.

[0066] Optionally, the cleaning device 100 may further include a second control board 10 , the sensing element 6 is electrically connected to the second control board 10 , the second control board 10 is electrically connected to the first control board 7 , and the steering information is sent to the first control board 7 via the second control board 10 .

[0067] Optionally, the cleaning device 100 may further include a rear wheel 8, and the steering direction of the brush body 1 is the same as that of the rear wheel 8. The sensing element 6 may include a magnetic member, and the magnetic member is used to sense the steering direction of the rear wheel 8.

[0068] In some embodiments, the cleaning device 100 further includes a housing for housing the roller brush assembly and the scraper bar assembly 2. The housing includes an upper housing 11 and a lower housing 12. The inner walls of the upper housing 11 and the lower housing 12 cooperate to form an arc-shaped cavity, and the arc-shaped movable scraper bar 201 is disposed within the arc-shaped cavity. This effectively guides the movable scraper bar 201 to move stably within the arc-shaped cavity and reduces the space occupied by the structure.

[0069] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
