[0002] The floor scrubber, as a cleaning equipment integrating sweeping, mopping and suction, has become an important cleaning tool in people's daily life. The floor scrubber usually comprises a floor scrubber head, a pole assembly and a dirt suction assembly. One end of the pole assembly is rotatably connected to the floor scrubber head, and the dirt suction assembly is arranged on the pole assembly. The floor scrubber head comprises a head, a roller brush assembly and a scraper blade assembly. The roller brush assembly is rotatably mounted on the front end of the head, the scraper blade assembly is mounted on the head, and the scraper blade assembly is located at the rear end of the roller brush assembly. The roller brush assembly and the scraper blade assembly are arranged at intervals, and the roller brush assembly and the scraper blade assembly both abut against the ground. The head is provided with a dirt suction channel and a dirt suction port, the dirt suction port is connected to one end of the dirt suction channel, and the other end of the dirt suction channel is connected to the space between the roller brush assembly and the scraper blade assembly, the dirt suction port is connected to the dirt suction assembly, the roller brush assembly rolls back the dirt, the scraper blade assembly blocks the dirt to prevent the dirt from retreating, and the dirt suction assembly provides negative pressure to the dirt suction channel, thereby passing the dirt into the dirt suction assembly through the dirt suction channel and the dirt suction port.

[0003] In the process of realizing the utility model, the inventor of the utility model found that: since the roller brush assembly and the scraper blade assembly are both in contact with the ground, the air in the gap between the roller brush assembly and the scraper blade assembly can only enter from the two ends of the roller brush assembly and the scraper blade assembly, and the sewage suction channel is trumpet-shaped, 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 space in the middle of the sewage suction channel is obviously larger than the space on both sides, and the two sides of the sewage suction channel are directly connected to the two ends of the gap between the roller brush assembly and the scraper blade assembly. Therefore, when the sewage suction channel is sucking sewage, the airflow directly enters the two sides of the sewage suction channel from the two ends of the roller brush assembly and the scraper blade assembly, and then enters the sewage suction port. Since there is no airflow entering the middle part, the suction force in the middle part is easily too low or even no suction, thereby causing dirt to accumulate in the middle part of the sewage suction channel.

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

[0028] 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.

[0029] See also Figure 1 The head 1000 of the floor scrubber comprises a roller brush assembly 1, a driving assembly 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 dirt suction channel 31 and a dirt suction port 32. The dirt suction port 32 is connected to one end of the dirt suction channel 31. The dirt suction channel 31 is horn-shaped. The dirt suction port 32 is used to connect an external dirt suction assembly. The scraper assembly 4 is fixed to 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. The gap is used to collect the dirt carried by the roller brush assembly 1 into the dirt suction channel 31 through the gap when the roller brush assembly 1 rotates. ; The other end of the sewage suction channel 31 is connected to the gap, and the roller brush assembly 1 and the scraper assembly 4 are both used to abut the plane to be cleaned. The roller brush assembly 1 abuts the plane to be cleaned to ensure that the roller brush assembly 1 is in full contact with the plane to be cleaned, which is beneficial to the roller brush assembly 1 to fully clean the plane to be cleaned. The abutment of the scraper assembly 4 with the plane to be cleaned ensures that the dirt carried by the roller brush assembly 1 can be guided into the sewage suction channel 31 by the scraper assembly 4, avoiding the dirt from contaminating the cleaned area during the carrying process; the drive assembly 2 is arranged on the head body 3, and the drive assembly 2 is located at the rear end of the scraper assembly 4, and the drive assembly 2 is used to drive the scraper assembly 4 to separate from the plane to be cleaned or abut against the plane to be cleaned.

[0030] When the scrubber head 1000 is at the end of cleaning, the driving component 2 drives the head body 3 away from the plane to be cleaned, thereby taking the scraper assembly 4 fixed to the head body 3 away from the plane to be cleaned, so that the air at the bottom of the scrubber head 1000 can enter the sewage suction channel 31 through the gap between the scraper assembly 4 and the roller brush assembly 1, thereby collecting the dirt accumulated in the sewage suction channel 31 away from the sewage suction port 32 into the external sewage suction assembly.

[0031] For drive assembly 2 above, see Figure 2 and Figure 3 The driving assembly 2 includes a driving member 21, a support rod 22 and a rotating wheel 23, one end of the support rod 22 is rotatably connected to the bottom surface of the head body 3, the other end of the support rod 22 is rotatably provided with a rotating wheel 23, and the support rod 22 is adjacent to the scraper assembly 4, the driving member 21 is provided on the head body 3, the driving member 21 is connected to the support rod 22, and the driving member 21 is used to drive the support rod 22 to rotate; the setting of the rotating wheel 23 is used to reduce the friction of the support rod 22 on the surface to be cleaned during the rotation process, so that the rotation of the support rod 22 is quieter and more labor-saving than that of the surface to be cleaned, and the rolling mode also protects the surface to be cleaned to avoid scratching the surface to be cleaned.

[0032] When the support rod 22 rotates to the preset first position, refer to Figure 3 , the height of the other end of the support rod 22 is higher than the bottom surface of the scraper assembly 4, that is, the height of the rotating wheel 23 is also higher than the bottom surface of the scraper assembly 4, the scraper assembly 4 and the roller brush assembly 1 are both in contact with the surface to be cleaned, and the gap between the scraper assembly 4 and the roller brush assembly 1 cannot allow external air to pass through;

[0033] When the support rod 22 rotates to the preset second position, refer to Figure 4 The height of the other end of the support rod 22 is lower than the bottom surface of the scraper assembly 4, and the other end of the support rod 22 is used to abut the plane to be cleaned, that is, the height of the rotating wheel 23 is lower than the bottom surface of the scraper assembly 4, and the rotating wheel 23 is used to abut the plane to be cleaned, and the head body 3 is lifted up under the action of the support rod, so that the scraper assembly 4 fixed to the head body 3 is lifted up, so that the scraper assembly 4 and the roller brush assembly 1 are both separated from the plane to be cleaned, and the air at the bottom of the head body 3 can easily enter the head body 3 through the gap between the scraper assembly 4 and the roller brush assembly 1.

[0034] It can be understood that the shape of the support rod 22 includes but is not limited to a rod, a plate, and a column. For example: when the support rod 22 is in the shape of a plate, the plate-shaped support rod 22 is arranged parallel to the axis of the roller brush assembly 1, one end of the plate-shaped support rod 22 is rotatably connected to the bottom surface of the head body 3, and the plurality of rotating wheels 23 are rotatably arranged at the other end of the plate-shaped support 22.

[0035] In some embodiments, the drive assembly 2 is provided with multiple groups, and the multiple groups of the drive assembly 2 are evenly arranged on the head body 3, so that the head body 3 is driven more smoothly by the drive assembly 2, and the multiple groups of drive assemblies 2 distribute the weight of the head body 3 to multiple drive assemblies 2, so that the load on a single drive assembly 2 is relatively reduced, thereby extending the service life of the drive assembly 2. For example: when the drive assembly 2 is two groups, the two groups of drive assemblies 2 are symmetrically arranged on the head body 3, and the drive assembly 2 is synchronously controlled and driven by an external controller to ensure that the drive assembly 2 works synchronously.

[0036] For the above-mentioned drive member 21, please refer to Figure 2 The driving member 21 includes a motor 211, a gearbox 212 and a transmission rod 213. The motor 211 and the gearbox 212 are both arranged in the machine head body 3. The motor 211 is connected to the gearbox 212. The gearbox 212 is connected to the support rod 22 through the transmission rod 213. One end of the transmission rod 213 extends into the machine head body 3 and is connected to the gearbox 212. The other end of the transmission rod 213 is connected to the support rod 22. The gearbox 212 is used to adjust the speed and torque of the motor 211, so that the high-speed rotation of the motor 211 is converted into a rotation suitable for driving the support rod 22 under the drive of the gearbox 212.

[0037] When the motor 211 rotates forward, the motor 211 drives the gearbox 212 to rotate, and the gearbox 212 drives the transmission rod 213 to rotate. During the rotation of the transmission rod 213, the support rod 22 directly connected to the transmission rod 213 rotates, thereby completing the conversion of the support rod 22 from the preset first position to the preset second position;

[0038] When the motor 211 reverses, the motor 211 drives the gearbox 212 to rotate, and the gearbox 212 drives the transmission rod 213 to rotate. During the rotation of the transmission rod 213, the support rod 22 directly connected to the transmission rod 213 rotates, thereby completing the conversion of the support rod 22 from the preset second position to the preset first position.

[0039] It can be understood that when the transmission rod 213 is extended into the head body 3, the head body 3 is provided with an insertion hole to facilitate the transmission rod 213 to extend into the head body 3, and a waterproof component can be provided at the insertion hole position, and the waterproof component is sleeved on the transmission rod 213, and the waterproof component is used to seal the transmission rod 213 and the head body 3 to prevent external dust and liquid from entering the head body 3 and causing damage to the floor scrubber.

[0040] In some embodiments, the head body 3 includes a height sensor (not shown), an alarm (not shown) and a circuit board (not shown). The height sensor is arranged in the head body 3, and a corresponding opening is arranged at the bottom of the head body 3 for the height sensor to transmit a corresponding signal to the plane to be cleaned. The height sensor is used to detect the distance between the head body 3 and the plane to be cleaned. The height sensor calculates the height of the height sensor from the ground according to the time from the emitted signal to the received signal, and transmits the obtained height detection data to the circuit board; the alarm and the circuit board are both arranged in the head body 3, the alarm is used to send a warning signal to the outside world, and the circuit board is electrically connected to the height sensor, the drive component 2, and the alarm respectively, and the circuit board is used to receive the detection data of the height sensor and the working signal of the drive component 2, and determine whether it is necessary to control the alarm to warn the outside world.

[0041] When the driving component 2 drives the support rod 22 to rotate from the preset first position to the preset second position, the alarm device determines whether the floor scrubber head 1000 is lifted according to the received forward rotation state of the motor 211 and the detection signal received by the height sensor. If it is lifted normally, the alarm device does not perform any operation; if it is not lifted, the alarm device sends a warning signal to the outside world so that the user can check the cause of the fault in time; when the driving component 2 drives the support rod 22 to rotate from the preset second position to the preset first position, the alarm device determines whether the floor scrubber head 1000 is lowered according to the received reverse rotation state of the motor 211 and the detection signal received by the height sensor. If it is lowered normally, the alarm device does not perform any operation; if it is not lowered, the alarm device sends a warning signal to the outside world so that the user can check the cause of the fault in time, thereby improving the intelligence of the operation of the floor scrubber and avoiding the user's failure to know in time when the driving component 2 fails.

[0042] In some embodiments, please combine Figure 5 and Figure 6The head body 3 also includes a receiving groove 33, which is located on the bottom surface of the head body 3, and the other end of the support rod 22 is rotatably connected to one side of the bottom of the receiving groove 33. When the support rod 22 is rotated to the preset first position, the rotating wheel 23 and the support rod 22 are both accommodated in the receiving groove 33.

[0043] It can be understood that when the support rod 22 and the rotating wheel 23 are located at the preset first position, the projection area of ​​the support rod 22 and the rotating wheel 23 in the receiving groove 33 is less than or equal to the positive projection area of ​​the receiving groove 33 at the bottom of the head body 3, so as to ensure that the support rod 22 and the rotating wheel 23 can be completely accommodated in the receiving groove 33.

[0044] For the scraper assembly 4, please refer to Figure 1 The scraper assembly 4 includes a mounting plate 41 and a flexible scraper head 42 , one end of the mounting plate 41 is fixed to the head body 3 , and the flexible scraper head 42 is fixed to the other end of the mounting plate 41 .

[0045] It can be understood that the connection methods of the scraper assembly 4 and the scrubber head 1000 include but are not limited to the following connection methods, such as: screw connection, clamping, welding, glue fixing, etc.

[0046] In this embodiment, the connection method between the scraper assembly 4 and the scrubber head 1000 is preferably a snap-on fixing method, a snap-on portion is provided at one end of the mounting plate 41, and a snap-on groove is correspondingly provided at one end of the head body 3 close to the roller brush assembly 1, the snap-on portion is snapped into the snap-on groove, so that the mounting plate 41 and the head body 3 are fixed, and a sealing strip can be provided between the mounting plate 41 and the head body 3, and the sealing strip is clamped between the head body 3 and the mounting plate 41, so that when the scrubber is in working state, the cleaning ability of the scrubber will not be reduced due to air leakage between the head body 3 and the mounting plate 41.
