[0002] As a cleaning equipment that integrates sweeping, mopping and vacuuming, a floor scrubber has become an important cleaning tool in people's daily life. A floor scrubber usually includes a floor scrubber head, a pole assembly and a sewage suction assembly. One end of the pole assembly is rotatably connected to the floor scrubber head, and the sewage suction assembly is arranged on the pole assembly. The floor scrubber head includes a head and a roller brush assembly. The roller brush assembly is rotatably installed at the front end of the head. The head is provided with a sewage suction channel and a sewage suction port. The sewage suction port is connected to one end of the sewage suction channel, and the other end of the sewage suction channel faces the roller brush assembly. The sewage suction port is connected to the sewage suction assembly. The roller brush assembly rolls back the sewage, and the sewage suction assembly provides negative pressure to the sewage suction channel, thereby passing the sewage into the sewage suction assembly through the sewage suction channel and the sewage suction port.

[0003] In the process of realizing the utility model, the inventor of the utility model found that: at present, the sewage suction channel is in the shape of a trumpet, and the diameter of the sewage suction channel gradually decreases from the other end of the sewage suction channel to one end of the sewage suction channel, and the roller brush assembly is in the shape of a cylinder, so that the closer the sewage suction channel is to the middle (that is, the position corresponding to the sewage suction channel and the sewage suction port), the larger the space between the sewage suction channel and the roller brush assembly, and the smaller the space between the sewage suction channel and the roller brush assembly is to the sides, while the negative pressure of the sewage suction port is the same, so that the closer the sewage suction channel is to the middle, the weaker the sewage suction ability, and the closer the sewage suction channel is to the sides, the stronger the sewage suction ability, which can easily cause the sewage in the middle of the sewage suction channel to not be sucked away due to the weak sewage suction ability, resulting in backlog.

[0007] Optionally, the first lever and the second lever are L-shaped, and the length of the first lever is smaller than the length of the second lever.

[0008] Optionally, the head body is provided with two receiving grooves on the inner wall of the sewage suction channel, the sewage suction port is located between the two receiving grooves, one end of one spoiler is rotatably connected to the inner wall of one receiving groove, and the other spoiler is rotatably connected to the inner wall of the other receiving groove; when the driving component drives the other ends of the two spoilers to rotate toward each other, the other ends of the two spoilers extend out of the two receiving grooves, and when the driving component drives the other ends of the two spoilers to rotate away from each other, the other ends of the two spoilers are received in the two receiving grooves.

[0009] Optionally, when the other ends of the two spoilers are respectively in contact with the bottoms of the two receiving grooves, the surfaces of the spoilers facing away from the bottoms of the receiving grooves are flush with the inner wall of the sewage suction channel.

When the spoiler rotates under the drive of the driving component, one of the spoilers rotates to a preset angle and then abuts against one of the limit parts.

[0012] Optionally, the head of the floor scrubber further includes a scraper blade assembly, which is disposed on the head body and located behind the roller brush assembly.

When the floor scrubber is in working state, due to the obstruction of the sewage suction channel by the roller brush assembly, the middle part of the sewage suction channel (i.e., the corresponding position of the sewage suction channel and the sewage suction port) has a smaller exchange area with the external air, and the dust and dirt accumulated in the middle part of the sewage suction channel due to insufficient suction force. When the floor scrubber with the floor scrubber head enters the final stage of the cleaning stage, the driving assembly drives the spoiler to rotate according to a preset program, and the spoiler and the sewage suction channel form a reinforced air duct, and the cross-sectional area of ​​the air inlet of the reinforced air duct is smaller than the cross-sectional area of ​​the air inlet of the sewage suction channel.

It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween.

The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0025] See also Figure 1The head 1000 of the floor scrubber comprises a roller brush assembly 1, a spoiler 2, a head body 3 and a scraper assembly 4; the roller brush assembly 1 is rotatably mounted on the front end of the head body 3, the head body 3 is provided with a sewage suction channel 31 and a sewage suction port 32, the sewage suction port 32 is connected to one end of the sewage suction channel 31, and the other end of the sewage suction channel 31 faces the roller brush assembly 1, the sewage suction channel 31 is trumpet-shaped, and a gap is formed around the roller brush assembly 1 and the sewage suction channel 31 to facilitate the inflow of external air, the sewage suction port 32 is used to connect an external sewage suction assembly, the spoiler 2 is arranged in the head body 3, and the spoiler 2 is used to change the suction force of the middle area of ​​the sewage suction channel 31, the scraper assembly 4 is arranged in the head body 3, and the scraper assembly 4 is located behind the roller brush assembly 1, there is a gap between the scraper assembly 4 and the roller brush assembly 1, and the other end of the sewage suction channel 31 is connected to the gap. When the floor scrubber head 1000 is working, the roller brush assembly 1 is in contact with the ground and rolls along with the operation of the floor scrubber head 1000, so that the dirt on the ground is rolled to the vicinity of the dirt suction channel 31. The external dirt suction assembly provides suction for the floor scrubber head 1000, so that negative pressure is formed in the dirt suction channel 31 of the floor scrubber head 1000, and the external air quickly flows into the dirt suction channel 31, thereby forming a complete dirt suction air path from the outside to the dirt suction channel 31 and then to the dirt suction assembly. Under the action of the dirt suction air path, the dirt rolled into the dirt suction channel 31 is collected into the dirt suction assembly. In the dirt suction air path, due to the obstruction of the roller brush assembly 1, the middle area of ​​the dirt suction channel 31 partially covered by the roller brush assembly 1 has insufficient suction, and dirt is prone to accumulation. The presence of the spoiler 2 enhances the suction in the middle area of ​​the dirt suction channel 31, thereby avoiding dirt accumulation and improving the cleaning effect and user experience of the floor scrubber.

[0026] For the above spoiler device 2, please refer to Figure 1 Combined with Figure 2 The spoiler device 2 includes a driving component 21 and two spoilers 22, one end of the two spoilers 22 is respectively rotatably connected to the head body 3 and the two opposite inner walls of the sewage suction channel 31, the sewage suction port 32 is located between the two spoilers 22, and the other ends of the two spoilers 22 extend toward the roller brush assembly 1, the driving component 21 is connected to the two spoilers 22, and the driving component 21 is used to drive the other ends of the two spoilers 22 to rotate toward or away from each other.

[0027] It can be understood that the extension length of the spoiler 22 toward the roller brush assembly 1 needs to be set accordingly according to the specific dirt accumulation position in the different suction channels 31 of different floor scrubbers, so as to avoid the spoiler 22 extending too long, blocking the dirt on both sides of the spoiler 22 from being collected into the external suction component, and to avoid the spoiler 22 extending too short, resulting in poor dirt suction effect of the suction air path formed by the spoiler 22 and the suction channel 31.

[0028] For the above drive assembly 21, please refer to Figure 1 Combined with Figure 3 The driving assembly 21 includes a motor 211, a lever box 212, a first lever 213 and a second lever 214. The motor 211 is arranged in the head body 3. The output end of the motor 211 is rotatably connected to the lever box 212. One end of the first lever 213 is connected to the lever box 212. The other end of the first lever 213 is connected to one of the spoilers 22. One end of the second lever 214 is connected to the lever box 212. The other end of the second lever 214 is connected to another of the spoilers 2 2, wherein the first lever 213 and the second lever 214 are L-shaped; the lever box 212 converts the rotation of the output end of the motor 211 into the reciprocating motion of the first lever 213 and the second lever 214 along the axial direction parallel to the output shaft of the motor 211, and the reciprocating motion of the first lever 213 and the second lever 214 causes the two spoilers 22 connected to the first lever 213 and the second lever 214 to reciprocate, thereby constituting the toward or away motion of the spoilers 22;

[0029] When the floor scrubber enters the cleaning tail stage, the motor 211 rotates forward, driving the first lever 213 and the second lever 214 to move toward each other, so that the two spoilers 22 rotate toward each other, and the two spoilers 22 and the upper inner wall of the sewage suction channel 31 and the lower inner wall of the sewage suction channel 31 together enclose a reinforced channel. In this reinforced channel, under the premise that the power of the external sewage suction component remains unchanged, the cross-sectional area of ​​the cross section of the reinforced channel parallel to the bottom surface of the sewage suction channel 31 is smaller than the cross-sectional area of ​​the cross section of the sewage suction channel 31 parallel to the bottom surface of the sewage suction channel 31. 1, so as to provide a stronger suction force for the area facing the channel, that is, the middle area of ​​the sewage suction channel 31, so as to facilitate more thorough cleaning of the dirt in the sewage suction channel 31; when the floor scrubber finishes cleaning, the motor 211 reverses to drive the first lever 213 and the second lever 214 to move in opposite directions, so that the two spoilers 22 rotate in opposite directions. At this time, the two spoilers 22 are attached to the inner wall of the sewage suction channel 31, and will not affect the operation of the air duct in the sewage suction channel 31.

[0030] In some embodiments, the lever box 212 is composed of gears, and a worm wheel meshing with a worm, which converts the rotation of the output end of the motor 211 into the reciprocating motion of the first lever 213 and the second lever 214 along the axial direction parallel to the output shaft of the motor 211. The gear mechanism is meshed with a plurality of gears with different numbers of teeth, and the deceleration effect is achieved by different combinations of different numbers of teeth of gears, so that the reciprocating motion of the first lever 213 and the second lever 214 can be carried out smoothly, and due to the mutual meshing of the worm wheel and the worm, the lever controls the spoiler 22 more accurately, and the working time of the motor 211 can be controlled to control the movement angle of the spoiler 22 towards each other or the movement angle of the spoiler 22 away from each other. There is self-locking between the worm wheel and the worm, and when the motor 211 stops rotating, the worm wheel and the worm do not move relative to each other, so that the two spoilers 22 respectively abutted by the first lever 213 and the second lever 214 no longer move.

[0031] It can be understood that the first lever 213 and the second lever 214 and the two spoilers 22 include but are not limited to the following connection methods: the first lever 213 and the second lever 214 are respectively connected to the two spoilers 22 in abutment, and the first lever 213 and the second lever 214 push the two spoilers 22 on different surfaces to achieve the rotation of the spoiler 22; the first lever 213 and the second lever 214 are respectively fixedly connected to the two spoilers 22, and the first lever 213 The first lever 213 and the second lever 214 are respectively connected to the gear box in rotation, such as a ball head connection, a universal connection, etc., so that when the first lever 213 and the second lever 214 respectively drive the spoiler to reciprocate, the first lever 213 and the second lever 214 can rotate at multiple angles at the rotation connection; a rack is provided at the top of the lever, and a gear is provided at the rotation position of the spoiler 22, and the gear is meshed with the rack. During the reciprocating motion of the lever, the rack drives the gear to rotate, thereby realizing the rotation of the spoiler 22.

[0032] It can be understood that the head body 3 is provided with two through holes in the sewage suction channel 31, and the two through holes are respectively adjacent to the rotation positions of the two spoilers, so that the first lever 213 can pass through one of the through holes, and the second lever 214 can pass through the other through hole, respectively driving the two connected spoilers 22 to move away from each other or towards each other, and corresponding rubber plugs are provided at the through holes to prevent the air in the head body 3 from passing through the through holes to affect the air duct of the sewage suction channel 31, and the setting of the rubber plug also plays a role in dustproof and waterproofing the inner wall of the sewage suction channel 31.

[0033] In some embodiments, the length of the first lever 213 is smaller than the length of the second lever 214, and the difference in length between the first lever 213 and the second lever 214 is greater than or equal to the distance between the two spoilers 22 and the connection positions in the sewage suction channel 31 respectively rotated to ensure that the end of the first lever 213 away from the lever box 212 can abut against one spoiler 22, and the end of the second lever 214 away from the lever box 212 can abut against the other spoiler 22.

[0034] In some embodiments, the spoiler device 2 includes two motors 211, two lever boxes 212, a first lever 213 and a second lever 214. One motor 211 is rotatably connected to one lever box 212 and connected to the first lever 213, and the other motor 211 is rotatably connected to the other lever box 212 and connected to the second lever 214, thereby forming two sets of drive assemblies 21, and the two sets of drive assemblies 21 respectively control the two spoilers 22.

[0035] In some embodiments, the spoiler 22 is not controlled by the driving component 21 to move toward or away from each other, but the two spoilers 22 are controlled by an electromagnetic device, and the two spoilers 22 are magnetically attracted to the inner wall of the sewage suction channel 31. When the spoiler 22 needs to be activated, the electromagnetic device is powered off, and the two spoilers 22 move toward each other under the suction force in the sewage suction channel 31. In addition, a limiting portion 34 is correspondingly provided to limit the angle of the two spoilers 22 moving toward each other to prevent the two spoilers 22 from covering the sewage suction port 32. When the spoiler 22 does not need to be activated, the electromagnetic device is powered on, and the two spoilers 22 are again adsorbed in the sewage suction channel 31 under the action of the electromagnetic force.

[0036] For the above-mentioned machine head body 3, please refer to Figure 1 Combined with Figure 4 , Figure 5 and Figure 6, including an upper cover (not marked) and a bottom shell (not marked), the upper cover covers the bottom shell, the spoiler device 2 is arranged in the bottom shell, and the upper cover, the bottom shell and the scraper assembly 4 together enclose the sewage suction channel 31. The head body 3 is provided with two receiving grooves 33 on the inner wall of the sewage suction channel 31, and the sewage suction port 32 is located between the two receiving grooves 33, one end of one of the spoilers 22 is rotatably connected to the inner wall of one receiving groove 33, and the other spoiler 22 is rotatably connected to the inner wall of the other receiving groove 33; when the driving assembly 21 drives the other ends of the two spoilers 22 to rotate toward each other, the other ends of the two spoilers 22 extend out of the two receiving grooves 33, when the driving assembly 21 drives the other ends of the two spoilers 22 to rotate away from each other, the other ends of the two spoilers 22 are received in the two receiving grooves 33, and when the When the other ends of the two spoilers 22 are respectively in contact with the bottoms of the two receiving grooves 33, the surfaces of the spoilers 22 facing away from the bottoms of the receiving grooves 33 are flush with the inner walls of the sewage suction channel 31, so as to ensure that the spoilers 22 will not generate disturbances to the sewage suction channel 31 after being received in the receiving grooves 33, and the projected area of ​​the spoilers 22 in the receiving grooves 33 is less than or equal to the cross-sectional area of ​​the receiving grooves 33 perpendicular to the depth direction of the receiving grooves 33, so as to ensure that the spoilers 22 can be completely received in the receiving grooves 33 and ensure the aesthetics of the spoilers 22 after being received in the receiving grooves 33.

[0037] In some embodiments, the head body 3 is provided with two limiting portions 34 in the sewage suction channel 31, and the two limiting portions 34 are respectively located at the groove edges of the two receiving grooves 33 close to the sewage suction port 32. When the spoiler 22 rotates under the drive of the driving component 21, one of the spoilers 22 rotates to a preset angle and then abuts against one of the limiting portions 34, thereby providing guarantee for the precise positioning of the spoiler 22 at the sewage outlet.

[0038] The utility model provides an embodiment of a floor scrubber 2000. Please refer to Figure 7 The floor scrubber 2000 includes a pole assembly (not marked), a dirt suction assembly (not marked) and the above-mentioned floor scrubber head 1000; one end of the pole assembly is rotatably connected to the head body 3 of the floor scrubber head 1000, the dirt suction assembly is installed on the pole assembly, and the dirt suction assembly is connected to the dirt suction port 32.

[0039] It can be understood that the design concept of the spoiler 22 of the utility model can also be used for devices that work on the suction principle, such as vacuum cleaners and exhaust fans.

[0040] The beneficial effects of the embodiment of the utility model are as follows: Different from the prior art, the embodiment of the utility model provides a floor scrubber head 1000 and a floor scrubber, the floor scrubber head 1000 includes a roller brush assembly 1; a head body 3, the roller brush assembly 1 is rotatably mounted on the front end of the head body 3, the head body 3 is provided with a sewage suction channel 31 and a sewage suction port 32, the sewage suction port 32 is connected to one end of the sewage suction channel 31, the other end of the sewage suction channel 31 faces the roller brush assembly 1, the sewage suction channel 31 is trumpet-shaped, and the sewage suction port 32 is connected to the roller brush assembly 1, and the sewage suction channel 31 is trumpet-shaped.
