Description

Technical Field

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

[0002] Cleaning equipment, used to clean the floor or countertop, usually includes a floor brush, a floor scrubber body, a cleaning charging stand, a sewage tank, a clean water tank, a motor battery assembly and other accessories. The floor brush is composed of a roller brush, a water spray assembly, a scraper, a suction channel, a roller brush motor, a water pump and other components. The cleaning charging stand generally has two functions: self-cleaning and charging. After the floor scrubber has washed and mopped the floor, dirt will adhere to the roller brush and the roller brush cavity. At this time, the floor scrubber is placed on the cleaning charging stand, and self-cleaning can be achieved through the cleaning slot on the cleaning charging stand, the scraper on the floor scrubber and the self-rotation of the roller brush.

[0003] However, after the floor scrubber performs self-cleaning, dirt will generally still adhere to the roller brush cavity, resulting in incomplete self-cleaning and poor cleaning effect. Summary of the invention

[0004] In view of this, the present invention provides a control device and a cleaning device for a scraper to solve the problem that after the floor scrubber self-cleans, dirt still adheres to the roller brush chamber, resulting in incomplete self-cleaning and poor cleaning effect.

[0005] In a first aspect, the present invention provides a control device for a scraper, wherein the scraper is movably connected to a floor scrubber and has a first cleaning position abutting against a roller brush and a second cleaning position separated from the roller brush; the control device comprises:

[0006] a driving structure, cooperating with the scraper, and used to drive the scraper to move from the first cleaning position to the second cleaning position;

[0007] A reset structure is connected between the floor scrubber and the scraper, and is used to drive the scraper to reset from the second cleaning position to the first cleaning position.

[0008] Beneficial effect: through the setting of the driving structure, when the floor scrubber is self-cleaning, the reset force of the reset structure can be overcome to drive the scraper to move from the first cleaning position to the second cleaning position, so that the scraper and the roller brush are arranged at an interval. At this time, a complete annular water film can be formed on the surface of the roller brush when the roller brush rotates. In addition to cleaning the roller brush, the complete annular water film can also flush the roller brush cavity to clean the dirt adhered to the roller brush cavity, thereby achieving a better cleaning effect; through the setting of the reset structure, when the driving structure does not apply force, the scraper can be driven to move from the second cleaning position to the first cleaning position, and a force can be applied to the scraper to keep it in the first cleaning position, so that the scraper and the roller brush are in contact, so that in the process of the floor scrubber cleaning the ground or the countertop, the scraper can scrape off the sewage, attached dust and other garbage on the roller brush, and the scraped sewage, dust and other garbage fall near the suction channel of the floor scrubber, and are sucked into the sewage tank through the suction channel, thereby better completing the cleaning process of the floor scrubber.

[0009] In an optional implementation, the driving structure includes:

[0010] A pressing driving member is rotatably connected to the cleaning and charging seat, and the pressing driving member includes a pressure-receiving end and a driving end;

[0011] A first elastic member connected between the cleaning and charging seat and the pressing driving member;

[0012] In which, the pressure-bearing end has a first position protruding from the cleaning and charging seat under the drive of the first elastic member, and a second position retracted into the cleaning and charging seat under the pressure of the floor scrubber placed on the cleaning and charging seat; the driving end is used to cooperate with the scraper when the floor scrubber is placed on the cleaning and charging seat.

[0013] Beneficial effect: When the floor scrubber is placed on the cleaning charging seat, the pressure end overcomes the elastic force of the first elastic part under the action of the gravity of the floor scrubber and moves from the first position to the second position, and drives the driving end to rotate. The scraper cooperating with the driving end overcomes the reset force of the reset structure and moves from the first cleaning position to the second cleaning position under the drive of the driving end, so that the scraper and the roller brush are arranged at a distance. If the roller brush is driven to rotate for self-cleaning at this time, a complete annular water film can be formed on the surface of the roller brush. In addition to cleaning the roller brush, the complete annular water film can also flush the roller brush cavity, clean the dirt adhered to the roller brush cavity, and achieve a better cleaning effect. After the floor scrubber is removed from the cleaning charging seat, the pressure-receiving end is no longer subjected to the pressure of the floor scrubber. The pressure-receiving end is reset from the second position to the first position under the elastic force of the first elastic member, and drives the driving end to rotate and reset; the driving end is separated from the floor scrubber and no longer applies force to the scraper. The scraper is driven from the second cleaning position to the first cleaning position by the reset force of the reset structure, and a force is applied to the scraper to maintain the first cleaning position, so that the scraper abuts against the roller brush, so that during the floor scrubber cleaning the ground or countertop, the scraper scrapes off the sewage, attached dust and other garbage on the roller brush, and the scraped sewage, dust and other garbage falls near the suction port channel of the floor scrubber, and is sucked into the sewage tank through the suction port channel, thereby better completing the cleaning process of the floor scrubber. By pressing the setting of the driving member and the first elastic member, the movement of the scraper can be automatically controlled by the weight of the floor scrubber itself, without the need for the customer to operate separately.

[0014] In an optional embodiment, the driving structure also includes a sliding plate, which is slidably connected to the scrubber; one end of the sliding plate is connected to the scraper, and the other end is provided with a sliding hole; after the scrubber is placed on the cleaning and charging seat, the driving end is inserted into the sliding hole.

[0015] Beneficial effect: Since the cleaning charging seat is provided with a cleaning groove, when the floor scrubber is placed on the cleaning charging seat, the roller brush is extended into the cleaning groove, and the roller brush can be self-cleaned by the water in the cleaning groove and the self-rotation of the roller brush; therefore, by setting the sliding plate, the pressing driving part and the cleaning groove can be separated in space, which can avoid interference and facilitate the pressing of the pressed end by the housing of the floor brush. And by setting the sliding hole, the driving end can be matched with the sliding plate by passing through the sliding hole, and the matching between the driving end and the sliding plate can be facilitated.

[0016] In an optional embodiment, the driving structure further includes a second elastic member, and one end of the sliding plate is connected to the scraper plate via the second elastic member.

[0017] Beneficial effect: By setting the second elastic member, the sliding force of the sliding plate can be transmitted to the scraper plate, and play a buffering role, and can better adapt to movements in different directions.

[0018] In an optional embodiment, the sliding plate is slidably connected to the inside of the housing of the floor scrubber, an insertion hole is provided on the housing, and the driving end passes through the insertion hole to cooperate with the sliding hole.

[0019] Beneficial effects: The sliding plate can be slidably connected to the inside of the housing of the floor scrubber, which can not only protect the sliding plate, but also maintain the integrity of the bottom of the floor scrubber, and avoid the sliding plate from rubbing and interfering with the ground or table when the floor scrubber is cleaning; through the setting of the insertion hole, the driving end located outside the housing can enter the interior of the housing through the insertion hole and cooperate with the sliding hole on the sliding plate.

[0020] In an optional embodiment, the driving structure further includes a sliding cover plate, which is fixedly connected to the floor scrubber and forms a sliding cavity with the floor scrubber, and the sliding plate is slidably disposed in the sliding cavity.

[0021] Beneficial effect: The setting of the sliding cover plate can not only protect the sliding plate, but also limit the sliding plate.

[0022] In an optional embodiment, the sliding cover plate is further provided with an avoidance hole, and the avoidance hole matches the position of the sliding hole.

[0023] Beneficial effect: The setting of the avoidance hole can avoid and limit the driving end, preventing the driving end and the sliding cover from interfering with and rubbing against each other.

[0024] In an optional embodiment, a first through hole and a second through hole are provided on the charging upper shell of the cleaning and charging seat at intervals; the pressing drive member is rotatably connected to the interior of the cleaning and charging seat, the pressure-bearing end is movably penetrated through the first through hole, and the driving end extends to the outside of the cleaning and charging seat through the second through hole.

[0025] Beneficial effects: The pressing drive member can be rotatably connected to the inside of the cleaning charging seat to protect the pressing drive member. The first perforation and the second perforation can facilitate the movement of the pressure-bearing end and the driving end, and can also limit and guide the pressure-bearing end and the driving end respectively.

[0026] In an optional embodiment, the pressing drive member includes:

[0027] A main body rod, one end of which is a rotating end and the other end is a reset end, the rotating end is rotatably connected to the charging bottom shell of the cleaning charging seat, and the first elastic member is connected between the reset end and the charging bottom shell;

[0070] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0071] The cleaning equipment is used to clean the floor or countertop, and usually includes a floor brush, a main body of the floor scrubber 100, a cleaning charging stand 200, a sewage tank, a clean water tank 108, a motor battery assembly and other accessories. The floor brush is composed of a roller brush 102, a water spray assembly, a scraper 101, a suction port channel, a roller brush 102 motor, a water pump and other components; the water spray assembly sprays water onto the roller brush 102 to wet the roller brush 102, and the wet roller brush 102 rolls on the floor to achieve the effect of washing and mopping the floor. In this process, the scraper 101 can scrape off the sewage, attached dust and other garbage on the roller brush 102, and the scraped sewage, dust and other garbage falls near the suction port channel of the floor scrubber 100, and is sucked into the sewage tank through the suction port channel. The cleaning charging stand 200 of the floor scrubber 100 generally has two functions: self-cleaning and charging. When the floor scrubber 100 is used for a period of time and the battery pack is out of power, the floor scrubber 100 can be charged by directly placing the floor scrubber 100 on the cleaning charging stand 200. After the floor scrubber 100 has washed and mopped the floor, dirt will adhere to the roller brush 102 and the roller brush chamber 104. At this time, the floor scrubber 100 is placed on the cleaning charging stand 200, and self-cleaning can be achieved through the self-rotation of the cleaning groove on the cleaning charging stand 200, the scraper 101 and the roller brush 102 on the floor scrubber 100.

[0072] However, since the scraper 101 is always in contact with the bristles of the roller brush 102, the roller brush 102 cannot form a complete surrounding water film during self-cleaning, and cannot flush the roller brush cavity 104, so that dirt is still adhered to the roller brush cavity 104, resulting in incomplete self-cleaning and poor cleaning effect.

[0073] Combine the following Figures 1 to 15 , describing an embodiment of the present invention.

[0074] According to an embodiment of the present invention, on the one hand, a control device for a scraper 101 is provided, wherein the scraper 101 is movably connected to a floor scrubber 100, and has a first cleaning position abutting against a roller brush 102, and a second cleaning position separated from the roller brush 102; the control device comprises a drive structure 1 and a reset structure 2; the drive structure 1 cooperates with the scraper 101 to drive the scraper 101 to move from the first cleaning position to the second cleaning position; the reset structure 2 is connected between the floor scrubber 100 and the scraper 101, and is used to drive the scraper 101 to reset from the second cleaning position to the first cleaning position.

[0075] By setting the driving structure 1, when the floor scrubber 100 performs self-cleaning, the reset force of the reset structure 2 can be overcome to drive the scraper 101 to move from the first cleaning position to the second cleaning position, so that the scraper 101 and the roller brush 102 are arranged with an interval. At this time, when the roller brush 102 rotates, a complete annular water film can be formed on the surface of the roller brush 102. In addition to cleaning the roller brush 102, the complete annular water film can also flush the roller brush cavity 104, clean the dirt adhered to the roller brush cavity 104, and achieve a better cleaning effect. By setting the reset structure 2, when the driving structure 1 does not apply a force, the scraper 101 can be driven to move from the second cleaning position to the first cleaning position, and a force can be applied to the scraper 101 to keep it in the first cleaning position, so that the scraper 101 abuts against the roller brush 102. When the floor scrubber 100 cleans the floor or table, the scraper 101 can scrape off the sewage, attached dust and other garbage on the roller brush 102. The scraped sewage, dust and other garbage fall near the suction channel of the floor scrubber 100 and are sucked into the sewage tank through the suction channel, thereby better completing the cleaning process of the floor scrubber 100.

[0076] In a specific embodiment, the scraper 101 is movably connected to the housing 103 of the floor brush of the floor scrubber 100, the roller brush cavity 104 is surrounded by a roller brush cover 105 connected to the housing 103, and at least part of the roller brush 102 is rotatably disposed in the roller brush cavity 104. In the rotation direction of the roller brush 102, the scraper 101 is movably connected to one side of the outside of the roller brush cavity 104.

[0077] In one embodiment, the driving structure 1 includes a pressing drive member 11 and a first elastic member 12; the pressing drive member 11 is rotatably connected to the cleaning and charging seat 200, and the pressing drive member 11 includes a pressure-receiving end 111 and a driving end 112; the first elastic member 12 is connected between the cleaning and charging seat 200 and the pressing drive member 11; wherein the pressure-receiving end 111 has a first position protruding from the cleaning and charging seat 200 under the drive of the first elastic member 12, and a second position retracted into the cleaning and charging seat 200 under the pressure of the floor scrubber 100 placed on the cleaning and charging seat 200; the driving end 112 is used to cooperate with the scraper 101 when the floor scrubber 100 is placed on the cleaning and charging seat 200.

[0078] When the floor scrubber 100 is placed on the cleaning charging seat 200, the pressure end 111 overcomes the elastic force of the first elastic member 12 under the action of gravity of the floor scrubber 100 and moves from the first position to the second position, and drives the driving end 112 to rotate. The scraper 101 cooperating with the driving end 112 overcomes the reset force of the reset structure 2 and moves from the first cleaning position to the second cleaning position under the drive of the driving end 112, so that the scraper 101 and the roller brush 102 are arranged at an interval. If the roller brush 102 is driven to rotate for self-cleaning at this time, a complete annular water film can be formed on the surface of the roller brush 102. In addition to cleaning the roller brush 102, the complete annular water film can also flush the roller brush cavity 104, clean the dirt adhered to the roller brush cavity 104, and achieve a better cleaning effect. After the floor scrubber 100 is removed from the cleaning charging seat 200, the pressure-bearing end 111 is no longer subjected to the pressure of the floor scrubber 100. The pressure-bearing end 111 is reset from the second position to the first position under the elastic force of the first elastic member 12, and drives the driving end 112 to rotate and reset; the driving end 112 is separated from the floor scrubber 100, and no longer applies force to the scraper 101. The scraper 101 is driven to move from the second cleaning position to the first cleaning position by the reset force of the reset structure 2, and a force is applied to the scraper 101 to maintain the first cleaning position, so that the scraper 101 abuts against the roller brush 102, so that during the process of the floor scrubber 100 cleaning the ground or the table, the scraper 101 scrapes off the sewage, attached dust and other garbage on the roller brush 102, and the scraped sewage, dust and other garbage falls near the suction port channel of the floor scrubber 100, and is sucked into the sewage tank through the suction port channel, thereby better completing the cleaning process of the floor scrubber 100. By pressing the drive member 11 and the first elastic member 12, the movement of the scraper 101 can be automatically controlled by the weight of the floor scrubber 100 itself, without the need for separate operation by the customer.

[0079] As a convertible embodiment, the driving structure 1 may include an automatic driving structure 1 such as a driving motor or a driving cylinder, and the power output end of the driving structure 1 is connected to the scraper 101 to drive the scraper 101 to move from the first cleaning position to the second cleaning position.

[0080] As a convertible embodiment, the driving structure 1 may also include a driving rod 115 and a driving handle, the driving rod 115 is connected to the scraper 101, the driving handle is connected to the driving rod 115, and the driving handle extends to the outside of the housing 103 of the floor brush of the floor scrubber 100, so as to facilitate applying force to the driving rod 115 through the driving handle to drive the scraper 101 to move from the first cleaning position to the second cleaning position.

[0081] In a specific embodiment, the scraper 101 is rotatably connected to the floor scrubber 100. Alternatively, the scraper 101 is slidably connected to the floor scrubber 100. In this embodiment, it is preferred that the scraper 101 is rotatably connected to the floor scrubber 100, and the scraper 101 occupies less space and has a simple structure.

[0082] In one embodiment, the driving structure 1 also includes a sliding plate 13, which is slidably connected to the scrubber 100; one end of the sliding plate 13 is connected to the scraper 101, and the other end is provided with a sliding hole 131; after the scrubber 100 is placed on the cleaning and charging seat 200, the driving end 112 is inserted into the sliding hole 131.

[0083] Since the cleaning charging seat 200 is provided with a cleaning groove, when the floor scrubber 100 is placed on the cleaning charging seat 200, the roller brush 102 is extended in the cleaning groove, and the roller brush 102 is self-cleaned by the water in the cleaning groove and the self-rotation of the roller brush 102; therefore, by setting the sliding plate 13, the pressing driving member 11 can be spaced from the cleaning groove in space, which can avoid interference and facilitate the housing 103 of the floor brush to press the pressed end 111. And by setting the sliding hole 131, the driving end 112 can be matched with the sliding plate 13 by passing through the sliding hole 131, and the matching between the driving end 112 and the sliding plate 13 can also be facilitated.

[0084] Specifically, the sliding hole 131 is a strip-shaped hole arranged along the sliding direction.

[0085] In one embodiment, the driving structure 1 further includes a second elastic member 14 , and one end of the sliding plate 13 is connected to the scraper 101 via the second elastic member 14 .

[0086] By providing the second elastic member 14 , the sliding force of the sliding plate 13 can be transmitted to the scraper 101 , and play a buffering role, and can better adapt to the movement in different directions.

[0087] In a specific embodiment, the second elastic member 14 is an elastic tension spring.

[0088] In one embodiment, the sliding plate 13 is slidably connected to the inside of the housing 103 of the floor scrubber 100 . The housing 103 is provided with an insertion hole 1031 . The driving end 112 passes through the insertion hole 1031 and cooperates with the sliding hole 131 .

[0090] In a specific embodiment, the insertion hole 1031 is a strip hole extending in the sliding direction, which can provide sufficient activity space for the driving end 112 to avoid interference with the movement of the driving end 112, and can also guide the movement of the driving end 112. When the scraper 101 is in the first cleaning position, the sliding hole 131 matches the position of the insertion hole 1031, which facilitates the cooperation between the driving end 112 and the sliding hole 131.

[0091] In one embodiment, the driving structure 1 further includes a sliding cover plate 15, which is fixedly connected to the floor scrubber 100 and forms a sliding cavity with the floor scrubber 100, and the sliding plate 13 is slidably disposed in the sliding cavity.

[0092] The arrangement of the sliding cover plate 15 can protect the sliding plate 13 and limit the position of the sliding plate 13 .

[0093] In a specific embodiment, the housing 103 of the floor brush of the floor scrubber 100 includes a floor brush bottom shell 1032 and a floor brush upper cover 1033, and the sliding plate 13 and the sliding cover plate 15 are arranged between the floor brush bottom shell 1032 and the floor brush upper cover 1033. A limiting groove is protruding from the floor brush bottom shell 1032, and an insertion hole 1031 is arranged at the bottom of the limiting groove. The notch of the limiting groove is detachably connected to the sliding cover plate 15, and the sliding cover plate 15 is surrounded to form a sliding cavity, and the sliding plate 13 is slidably arranged in the sliding cavity. In a preferred embodiment, a buckle is provided on the groove wall of the limiting groove, and a buckle is protruding from the sliding cover plate 15, and the buckle is engaged with the buckle. A clean water tank 108 is also provided on the floor brush, which is connected to the floor brush upper cover 1033. A floor brush connector 106 and a power-assisted wheel 107 are also provided on the floor brush.

[0094] In one embodiment, the sliding cover plate 15 is further provided with an avoidance hole 151 , and the avoidance hole 151 matches the position of the sliding hole 131 .

[0095] The setting of the avoidance hole 151 can avoid and limit the driving end 112, thereby preventing the driving end 112 and the sliding cover plate 15 from interfering with and rubbing against each other.

[0096] In a specific embodiment, the avoidance hole 151 is a strip-shaped hole arranged along the sliding direction.

[0097] In one embodiment, a first through hole 2011 and a second through hole 2012 are spaced apart on the charging upper shell 201 of the cleaning and charging seat 200; the pressing drive member 11 is rotatably connected to the inside of the cleaning and charging seat 200, the pressure-bearing end 111 is movably penetrated through the first through hole 2011, and the driving end 112 extends to the outside of the cleaning and charging seat 200 through the second through hole 2012.

[0098] The pressing drive member 11 is rotatably connected to the interior of the cleaning charging seat 200 to protect the pressing drive member 11.
