[0002] Floor scrubbers are a common type of cleaning equipment. Their floor brush mechanism primarily consists of a roller, a roller brush, a scraper bar, and a drive control unit. The roller brush is located in front of the roller to clean the floor, and together they support the entire machine's operation. The scraper bar, located behind the roller, removes water stains left by the roller brush when the scrubber is pushed forward. The roller brush also leaves water stains on the floor when the scrubber is pulled backward. Currently, neither adopting a more water-soluble brush material nor reducing the water output of the water pump has effectively solved the problem of residual water stains when the scrubber is pulled backward.

[0077] The following combination Figures 1-17 , Table 1, describes the embodiments of the present utility model.

[0078] According to an embodiment of the present invention, on the one hand, a floor brush device of a cleaning device is provided, such as Figure 1 、 Figure 2 、 Figure 3 As shown, it includes a floor brush body 10 and a cleaning member 1 provided on the floor brush body 10 .

[0079] Specifically, the floor brush body 10 serves as the installation base of the cleaning member 1, and is internally provided with components such as a drive control circuit and a main control board; the cleaning member 1 is used to clean the floor, and can specifically be a plate-shaped cleaning member, a roller brush, etc.

[0080] The floor brush device further includes: a cover plate 3, a first scraper strip 301, a drive assembly 4 and an electronic control assembly.

[0081] The cover plate 3 is movably connected to the floor brush body 10, and a first scraper 301 is provided on one side of the cover plate 3, and the first scraper 301 is provided in front of the cleaning member 1; the driving component 4 is transmission-connected to the cover plate 3, and the driving component 4 is suitable for driving the cover plate 3 to move so that the first scraper 301 leaves the ground or contacts the ground; the electronic control component is communication-connected to the driving component 4, and the electronic control component is suitable for detecting the driving state of the floor brush device, so as to control the driving component 4 to drive the cover plate 3 to move when the floor brush device is in a backward state, so that the first scraper 301 is in a state of contacting the ground.

[0082] In the above embodiment, a cover plate 3 having a first scraper 301 is provided, and a driving component 4 controlled and driven by an electronic control component is used to drive the cover plate 3 to move, thereby driving the first scraper 301 to lift or fall, so that the first scraper 301 leaves the ground or contacts the ground. When the floor brush device is in the backward state, the first scraper 301 falls and contacts the ground, and can scrape away the water stains left on the ground by the cleaning member 1, thereby solving the problem that the floor brush device is prone to leaving water stains on the ground when the current cleaning equipment is in use.

[0083] Furthermore, when the floor brush device is in the forward state, the first scraper bar 301 is lifted up and leaves the ground, so as to avoid the garbage in front of the cleaning member 1 so as to facilitate cleaning by the cleaning member 1 .

[0084] Specifically, if Figure 1 、 Figure 2 、 Figure 3 As shown, the cover plate 3 is entirely arranged at the front position of the floor brush body 10 and extends in the direction of the cleaning member 1. On the side close to the cleaning member 1, it is contoured with the cleaning member 1 so that one side of the cover plate 3 extends to the front of the cleaning member 1, and a first scraper bar 301 is arranged on this side so that the first scraper bar 301 is located in front of the cleaning member 1.

[0085] Further, if Figure 1 、 Figure 2 As shown, a second scraper bar 2 is also provided on the floor brush body 10. The second scraper bar 2 is provided behind the cleaning member 1 and is used to scrape away water stains left on the ground by the cleaning member 1 when the floor brush device is in the forward state. In this way, the first scraper bar 301 is used to scrape away water stains left on the ground by the cleaning member 1 when the floor brush device is in the backward state, thereby ensuring that the floor brush device will not leave water stains on the ground when the cleaning equipment is in use.

[0086] Furthermore, this embodiment does not impose any restrictions on the specific structural form of the cover plate 3 being movably connected to the floor brush body 10. In one embodiment, the cover plate 3 is rotatably connected to the floor brush body 10, and when the drive assembly 4 drives the cover plate 3 to move, the cover plate 3 rotates relative to the floor brush body 10, so that the first scraping bar 301 leaves the ground or contacts the ground. In another embodiment, the cover plate 3 is arranged as a whole to be tilted downward relative to the floor brush body 10, and when the drive assembly 4 drives the cover plate 3 to move, the cover plate 3 moves translationally relative to the floor brush body 10, so that the first scraping bar 301 leaves the ground or contacts the ground.

[0087] Furthermore, this embodiment does not limit the specific arrangement of the transmission connection between the drive assembly 4 and the cover plate 3. As one embodiment, the drive assembly 4 is configured as a motor located at the connection position between the cover plate 3 and the floor brush body 10, the motor is mounted to the floor brush body 10, and its output shaft is coaxially arranged with the rotation axis of the cover plate 3, and the cover plate 3 is directly driven to rotate by the motor; as another embodiment, the drive assembly 4 is configured as a combination of a motor and a transmission structure, the transmission structure including but not limited to a rack and pinion transmission, a worm gear transmission, etc., and the motor drives the above-mentioned transmission structure to indirectly drive the cover plate 3 to rotate.

[0088] Furthermore, this embodiment does not limit the specific configuration of the electronic control component, which can be configured as a position sensor, an infrared sensor, etc., and can be used in conjunction with a corresponding control system.

[0089] In some embodiments, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the floor brush device further includes a roller 7 rotatably connected to the floor brush body 10 .

[0090] As one embodiment, the roller 7 can be driven by a power drive component, thereby driving the floor brush body 10 forward or backward, making the operation of the floor brush device more labor-saving; as another embodiment, the roller 7 is only arranged on the floor brush body 10 as a supporting structure, which improves the smoothness of the floor brush device while saving the manufacturing cost of the floor brush device.

[0091] The electronic control component includes: a detection device 5 and a first controller 6.

[0092] The detection device 5 is suitable for detecting the driving state of the roller 7 and sending the first position information; the first controller 6 is communicatively connected with the driving component 4 and the detection device 5 respectively, and the first controller 6 is suitable for controlling the driving component 4 according to the first position information so that the first scraper 301 leaves the ground or contacts the ground.

[0093] In the above embodiment, the driving state of the roller 7 is detected by the detection device 5, and the first position information obtained by the detection is sent to the first controller 6, so that the first scraper 301 is controlled to be lifted or lowered by the first controller 6 to realize automatic control.

[0094] Specifically, if Figure 1 、 Figure 2 、 Figure 4 As shown, when the detection device 5 detects that the driving state of the roller 7 is the forward state, the first position information of the roller 7 in the forward state is sent to the first controller 6; the first controller 6 controls the driving component 4 according to the corresponding first position information to lift the first scraper 301; when the detection device 5 detects that the driving state of the roller 7 is the backward state, the first position information of the roller 7 in the backward state is sent to the first controller 6; the first controller 6 controls the driving component 4 according to the corresponding first position information to drop the first scraper 301.

[0095] Furthermore, if Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, this embodiment does not limit the specific setting form of the detection device 5. It can know the driving state of the roller 7 by detecting the rotation state of the roller 7. Therefore, the detection device 5 can be a grating sensor device, a photoelectric coupling sensor device, etc.

[0096] Furthermore, a main control board is provided in the floor brush body 10 , and the first controller 6 is provided on the main control board.

[0098] Table 1

[0099] In some embodiments, as Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown in Table 1, the floor brush device further includes a roller motor 8 that is transmission-connected to the roller 7 , and the roller motor 8 is provided on the floor brush body 10 .

[0100] Specifically, the roller motor 8 is used to drive the roller motor 8 to rotate, thereby driving the floor brush body 10 forward or backward, making the operation of the floor brush device more labor-saving.

[0101] The detection device 5 includes a grating plate 501 , a transmitting element 502 and a receiving element 503 .

[0102] The grating plate 501 is connected to the roller motor 8 and is coaxially arranged with the roller 7. A plurality of light-transmitting holes 5011 are arranged circumferentially of the grating plate 501. The emitting element 502 and the receiving element 503 are relatively fixedly arranged on both sides of the grating plate 501. When the grating plate 501 rotates with the movement of the roller 7, a grating signal is generated between the emitting element 502 and the receiving element 503, and the driving state of the roller 7 is determined by the grating signal.

[0103] In the above embodiment, by providing a grating plate 501 having a plurality of light-transmitting holes 5011, and cooperating with the emitting element 502 and the receiving element 503 on both sides of the grating plate 501, when the grating plate 501 rotates with the movement of the roller 7, due to the obstruction of the grating plate 501, the signal transmission between the emitting element 502 and the receiving element 503 will be on and off in a certain sequence, thereby forming a grating signal, and then the driving state of the roller 7 can be determined based on the grating signal.

[0104] Specifically, if Figure 5 、 Figure 6 As shown, the emitting element 502 is configured as an emitting LED, and the receiving element 503 is configured as a receiving LED; the emitting LEDs are arranged in two groups along the radial direction of the grating sheet 501, namely the first emitting LED and the second emitting LED, and the receiving LEDs are arranged in two groups along the radial direction of the grating sheet 501, namely the first receiving LED and the second receiving LED, wherein the spacing between the first emitting LED and the second emitting LED corresponds to the plurality of light-transmitting holes 5011 plus half the position of the light-transmitting holes 5011; the first receiving LED and the first emitting LED are arranged in alignment, and the second receiving LED and the second emitting LED are arranged in alignment.

[0105] Furthermore, if Figure 7 、 Figure 8As shown in Table 1, when the grating sheet 501 rotates with the movement of the roller 7, one of the first transmitting LED and the second transmitting LED may be half-covered by the grating sheet 501, and the other may be completely covered by the grating sheet 501; this causes the receiving lights between the first receiving LED and the first transmitting LED, and between the second receiving LED and the second transmitting LED to be on and off in a certain order, and the above on and off are converted into binary 1 and 0, that is, Figure 8 The four stages are sorted as shown in Table 1, which means that the roller 7 is Figure 1 In the middle, the grating piece 501 rotates counterclockwise, and the floor brush device as a whole is in the forward direction; when the floor brush device as a whole moves backward, the situation is opposite to the above situation.

[0106] In some embodiments, as Figure 3 、 Figure 5 As shown, two rollers 7 are symmetrically arranged, and the two rollers 7 are each provided with a detection device 5.

[0107] In the above embodiment, the detection device 5 is provided at both rollers 7 to improve the detection accuracy.

[0108] Specifically, if Figure 3 、 Figure 5 As shown, the rear middle portion of the floor brush body 10 extends outward to form a mounting position for the roller 7 , and two rollers 7 are symmetrically mounted on both sides of the extension structure, and each roller 7 is driven by a roller motor 8 .

[0109] In some embodiments, as Figure 5 、 Figure 9 、 Figure 10 As shown, the driving assembly 4 includes: an adjusting motor 401 , a gear 402 and a rack 403 .

[0110] An adjusting motor 401 is provided on the floor brush body 10, and a gear 402 is provided at the output end of the adjusting motor 401; a rack 403 is engaged with the gear 402, and an end of the rack 403 is transmission-connected to a side of the cover plate 3 away from the first scraper bar 301; when the rack 403 is driven to descend, the cover plate 3 is driven to rotate in a first direction, so that the first scraper bar 301 is lifted to leave the ground; when the rack 403 is driven to ascend, the cover plate 3 is driven to rotate in a second direction, so that the first scraper bar 301 falls to contact the ground; the first direction and the second direction are opposite to each other.

[0111] In the above embodiment, the driving power provided by the regulating motor 401 drives the transmission fittings composed of the driving gear 402 and the rack 403 to move, thereby driving the driving cover 3 to rotate, thereby driving the first scraper 301 to be lifted or lowered.

[0112] Specifically, the middle part of the floor brush body 10 of the cover plate 3 is rotatably connected, and a first scraper bar 301 is provided at the edge position of the cover plate 3 on one side of the connection position, and a vertically arranged rack 403 is transmission-connected to the edge position of the cover plate 3 on the other side of the connection position; with the rotational connection position between the cover plate 3 and the floor brush body 10 as the fulcrum, when the rack 403 is driven to descend, the first scraper bar 301 rises, that is, a lifting action is performed; when the rack 403 is driven to rise, the first scraper bar 301 descends, that is, a falling action is performed.

[0113] Furthermore, this embodiment does not restrict the specific form of transmission connection between the end of the rack 403 and the cover plate 3. In one embodiment, the end of the rack 403 abuts the bottom of the cover plate 3 on the side away from the first scraper 301. In this case, the upward movement of the rack 403 can lift the cover plate 3, and the downward movement of the rack 403 causes the cover plate 3 to fall back under the action of gravity. In another embodiment, the end of the rack 403 is rotationally connected to the side of the cover plate 3 away from the first scraper 301. In this case, the rack 403 can directly drive the movement of the cover plate 3, and the connection between the rack 403 and the cover plate 3 is more stable. This embodiment adopts the second embodiment.

[0114] Further, in Figure 9 From the perspective of , when the floor brush device needs to drive the first scraper 301 to lift up when it moves forward, the motor 401 is adjusted to drive the gear 402 to rotate counterclockwise to drive the rack 403 to descend, and the cover plate 3 rotates clockwise with its rotational connection position with the floor brush body 10 as a fulcrum, thereby driving the first scraper 301 to rise to lift; when the floor brush device needs to drive the first scraper 301 to fall when it moves forward, the motor 401 is adjusted to drive the gear 402 to rotate clockwise to drive the rack 403 to rise, and the cover plate 3 rotates counterclockwise with its rotational connection position with the floor brush body 10 as a fulcrum, thereby driving the first scraper 301 to fall.

[0115] In some embodiments, the floor brush device further includes a limiting assembly 9, which is adapted to limit the rotation of the cover plate 3 so that the first scraper strip 301 is lifted or dropped to a preset position.

[0116] In the above embodiment, the limiting assembly 9 is provided to ensure that the cover plate 3 moves to the correct position after the first scraper strip 301 is lifted or lowered.

[0117] Specifically, in actual application, when the floor brush device moves forward, it is necessary to ensure that the position of the first scraper 301 after it is lifted is a certain distance from the ground to avoid blocking the cleaning member 1 behind the first scraper 301 from cleaning the ground garbage normally. When the floor brush device moves backward, the first scraper 301 needs to be as close to the ground as possible after it falls to achieve the best wiping effect; therefore, a limit component 9 is provided to limit the position of the first scraper 301 when it is lifted or fallen, so that the first scraper 301 can be lifted or fallen to a preset position.

[0118] In some embodiments, as Figure 1 As shown, when the floor brush device is in the forward state, the first scraping bar 301 is in the state of leaving the ground, and the distance between the first scraping bar 301 and the ground is in the range of 10 cm to 12 cm.

[0119] Specifically, if Figure 1 As shown, when the floor brush device is in the forward state, if the distance between the first scraper 301 and the ground is too small, it is easy to block the suction of some garbage; if the distance between the first scraper 301 and the ground is too large, it is easy to cause the cover plate 3 to fail to block the garbage well. At this time, some garbage will splash out from the upper part of the roller brush as the cleaning member 1, that is, the roller brush, rotates. At the same time, it will also make the height of the cover plate 3 higher, affecting the cleaning of low areas such as the bottom of the bed. Therefore, when the floor brush device is in the forward state, the numerical setting of the distance between the first scraper 301 and the ground is obtained after balancing various factors.

[0120] Furthermore, if Figure 1 As shown, when the floor brush device is in the forward state, the distance between the first scraping strip 301 and the ground is preferably 10 cm.

[0121] In some embodiments, as Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 As shown, the limiting assembly 9 includes: a first blocking piece 901 , a second blocking piece 902 , a photoelectric switch 903 and a second controller 904 .

[0122] The first baffle 901 and the second baffle 902 are arranged in the same direction and spaced apart on the rack 403; the photoelectric switch 903 is arranged corresponding to the first baffle 901 and the second baffle 902, and the photoelectric switch 903 has a transmitting end 9031 and a receiving end 9032, which are suitable for sensing the positions of the first baffle 901 and the second baffle 902 and sending second position information; the second controller 904 is communicatively connected to the adjustment motor 401 and the photoelectric switch 903 respectively, and the second controller 904 is suitable for controlling the adjustment motor 401 to stop running according to the second position information.

[0123] In the above embodiment, the transmitting end 9031 and the receiving end 9032 on the photoelectric switch 903 generate the second position information and send it to the second controller 904 by sensing the positions of the first baffle 901 and the second baffle 902 on the rack 403. The second controller 904 controls the adjustment motor 401 to stop running according to the second position information, thereby stopping the driving action of the cover 3 when the first scraper 301 can be lifted or dropped to the preset position, and electrically limiting the cover 3 and the first scraper 301 thereon.

[0124] Specifically, Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 As shown, the first baffle 901 is located above the second baffle 902 , and the photoelectric switch 903 is arranged horizontally, with the transmitting end 9031 and the receiving end 9032 arranged horizontally thereon.

[0125] Furthermore, a main control board is provided in the floor brush body 10 , and the second controller 904 is provided on the main control board.

[0126] In some embodiments, as Figure 15 、 Figure 16 、 Figure 17 As shown, the limiting assembly 9 includes: a coupling member 905 and an elastic member.

[0127] The coupling 905 is movably arranged in the cover plate 3. The coupling 905 is provided with a first rotating shaft 9051 and a second rotating shaft 9052. The first rotating shaft 9051 is rotatably connected to the floor brush body 10, and the second rotating shaft 9052 is rotatably connected to the rack 403; the end of the first rotating shaft 9051 is provided with a rotary buckle 9053, which is suitable for abutting against the floor brush body 10 to limit the rotation of the cover plate 3; the elastic member is arranged between the cover plate 3 and the coupling 905 along the extension direction of the coupling 905.

[0128] In the above embodiment, as the cover plate 3 rotates, the coupling 905 can be extended and retracted relative to the cover plate 3 in the transverse direction under the action of the elastic member, so that the knob 9053 can be extended and retracted; after the first scraper 301 is lifted or dropped into place, that is, after the cover plate 3 is rotated into place, the knob 9053 can be fully extended and abutted against the floor brush body 10, thereby limiting the cover plate 3 from continuing to rotate, and mechanically limiting the cover plate 3 and the first scraper 301 thereon.

[0129] Specifically, if Figure 15 、 Figure 16 、 Figure 17 As shown, the coupling 905 is L-shaped as a whole, the first rotating shaft 9051 and the second rotating shaft 9052 are arranged in the same direction, and a clearance hole connected to the inner cavity is opened on the surface of the cover plate 3 to allow the first rotating shaft 9051 and the second rotating shaft 9052 on the coupling 905 located in the inner cavity of the cover plate 3 to extend, thereby being rotatably connected to the floor brush body 10 and the rack 403.

[0130] Further, if Figure 15 、 Figure 16 As shown, an avoidance hole 1001 is provided on the top cover of the floor brush body 10 to facilitate the rack 403 to extend from the interior of the floor brush body 10 and thus be rotatably connected to the second rotating shaft 9052 .

[0131] It should be noted that the above embodiment provides two implementations of the limiter assembly 9: one is an electrically controlled limiter consisting of a first baffle 901, a second baffle 902, a photoelectric switch 903, and a second controller 904; the other is a mechanical limiter consisting of a coupling 905 and an elastic member. In practical applications, either limiter can be used, or the floor brush device can be designed with the structures associated with both limiters to provide a dual limit effect on the cover plate 3 and the first scraper strip 301 thereon.

[0132] In some embodiments, as Figure 16 、 Figure 17 As shown, there are two coupling members 905 , and the two coupling members 905 are symmetrically arranged in the cover plate 3 body.

[0133] In the above embodiment, two couplings 905 are provided to provide two symmetrically arranged first rotating shafts 9051 and two second rotating shafts 9052 , thereby improving the stability of the rotational connection between the cover plate 3 and the floor brush body 10 and the rack 403 .

[0134] Specifically, if Figure 16 、 Figure 17 As shown, the two couplings 905 are symmetrically arranged, so that the two first rotating shafts 9051 can be arranged back to back, so that the two first rotating shafts 9051 can be rotationally connected to the floor brush body 10; at the same time, the two second rotating shafts 9052 can be arranged back to back, so that the two second rotating shafts 9052 can be rotationally connected to the rack 403.

[0135] According to an embodiment of the present invention, on the other hand, a cleaning device is provided, such as Figure 1 、 Figure 2 As shown, the floor brush device of the cleaning device includes any one of the above embodiments.

[0136] Specifically, the cleaning device is configured as a floor scrubber, the floor brush body 10 is the floor brush portion at the bottom of the floor scrubber, and a hand-operated portion is further provided on the upper portion of the floor brush body 10 .

[0137] Furthermore, as an alternative embodiment, the cleaning device may also be an electrically controlled flat mop with a scraper.

[0138] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by this application.
