[0003] The floor brushes of existing cleaning machines are usually equipped with a roller brush with fluff or planted hair. In order to increase the suction force, a one-way scraper is also provided on the rear side of the floor brush suction port. During the cleaning operation, most of the water and dirt are thrown out and sucked away after the roller brush meets water, and only a small amount of residue cannot be completely thrown out. During the movement of the cleaning machine, the water will be spread again on the surface to be cleaned, causing secondary pollution. If the floor brush head allows the suction of large particles, more space should be reserved at the front end to allow large particles to pass through, which will cause the suction power of the floor brush suction port to decrease, and the residual water will increase, which will seriously affect the drying time of the floor and lead to low cleaning efficiency.

DETAILED DESCRIPTION
[0011] Embodiment 1 Figure 1 This is a schematic diagram of the control mechanism structure of Embodiment 1 of the present invention; Figure 2 Schematic diagram of the first scraper strip, the second scraper strip and the roller brush structure of the first embodiment of the present invention. Figure 1 Combined with Figure 2 As shown, the present invention provides a floor cleaning device, including a walking wheel 400, a roller brush 100 and a control mechanism arranged thereon, a first scraping bar 200 is arranged on the front side of the roller brush 100, and the control mechanism includes a trigger component and an execution component, the trigger component is connected to the walking wheel 400, and the execution component is connected to the first scraping bar 200. During the walking process of the walking wheel 400, the trigger component is triggered, a trigger signal is sent to start the execution component, and the first scraping bar 200 is driven to rotate through the execution component to change the angle between the first scraping bar 200 and the surface to be cleaned.
[0012] Specifically, the trigger component and the execution component in the control mechanism of the first wiper strip 200 can be implemented by various structures, such as Figure 1 Combined with Figure 2 As shown, in this embodiment, the trigger assembly includes a trigger rod 510 and a correspondingly arranged signal switch 520, the trigger rod 510 is fixed on the walking wheel 400 and rotates synchronously therewith, and the signal switch 520 is fixed on the body of the floor cleaning device. The execution assembly includes a first stepper motor 530 connected to the first scraper bar 200. The rotation of the walking wheel 400 drives the trigger rod 510 to rotate, thereby toggling the signal switch 520, and the signal switch 520 outputs a position signal and starts the first stepper motor 530, and the first stepper motor 530 drives the first scraper bar 200 to flip.
[0013] like Figure 1 As shown, the trigger rod 510 includes a disk 511 and a protrusion 512 arranged on the inner side of the outer edge of the disk 511. The trigger rod 510 is fixed to the body of the floor cleaning device through a base connection end 540. A spring 513 is arranged between the disk 511 and the base connection end 540. A stopper 541 is convexly arranged on the outer circumference of the base connection end 540. The signal switch 520 is provided with a contact 521, and the contact 521 is arranged corresponding to the protrusion 512. When the walking wheel 400 rotates, it drives the trigger rod 510 to rotate, and the protrusion 512 arranged on the trigger rod 510 will also rotate together, and rotate to Figure 1 As shown, when it approaches the lower right side, it will contact the contact 521 and trigger it. The disk 511 of the trigger lever 510 is connected to the running wheel 400. In order to effectively prevent the trigger lever and the running wheel 400 from slipping, a friction plate 550 is provided between the connection positions of the two. If the friction plate 550 and the trigger lever 510 are made of different materials, it may be better to prevent the two from slipping during the rotation process.
[0014] Figure 3 and Figure 4 The schematic diagrams of the positions of the first scraper strip in the forward and backward states of the first embodiment of the present invention are shown respectively. Figure 3 Combined with Figure 4 As shown, in this embodiment, the working process of the control mechanism is as follows: like Figure 3 Combined with Figure 1 As shown, when the floor cleaning device is in the forward state, the travel wheel 400 drives the trigger rod 510 to rotate through the friction plate 550. Figure 1 When the position is close to the lower right side, the protrusion 512 contacts and triggers the contact 521 provided on the signal switch 520, and the signal switch 520 outputs a signal to the first stepper motor 530. At this time, the first stepper motor 530 starts and drives the first scraper bar 200 to flip. The first scraper bar 200 flips to an angle of about 65° with the ground, that is, it is in an open state. The first scraper bar 200 remains open during the forward movement of the floor cleaning device to allow large particles to enter.
[0015] like Figure 4 Combined with Figure 1As shown, when the floor cleaning device is in the backward state, the running wheel 400 drives the trigger rod 510 to rotate in the opposite direction through the friction plate 550, and the protrusion 512 will be separated from the contact 521 set on the signal switch 520. The signal switch 520 outputs a signal to the first stepper motor 530. At this time, the first stepper motor 530 stops and the first scraper 200 is reset to a position perpendicular to the ground. The first scraper 200 remains in contact with the ground to remove residual moisture on the ground. Since a stopper 541 is provided on the circumferential surface of the base connection end 540, even if the running wheel 400 continues to rotate, the trigger rod 510 will no longer continue to rotate under the blocking effect of the stopper 541 on the protrusion 512, and the contact 521 will not be triggered again. Since the trigger rod 510 is pressed by the spring 513 to a certain position, the trigger rod 510 will stop rotating and slide frictionally with the running wheel 400.
[0016] It can be known from the above working process that the present invention realizes the flipping of the first scraper bar 200 through the control mechanism, which is mainly aimed at large particles and floor cleaning machines with a floor drying time of less than 1 minute. When moving forward, the first scraper bar is retracted to allow large particles to pass through. When moving backward, the first scraper bar is perpendicular to the ground to scrape away residual water and other substances on the ground, thereby achieving the purpose of less than 1 minute of floor drying time. Therefore, the present invention solves the problem of low suction power of large particles through the front adaptive scraper bar, while significantly improving the cleanliness of the ground in one cycle and shortening the drying time of the ground. Without occupying too much space of the floor cleaning device, adding this structure greatly improves the user experience, allowing particles with a height of no more than 8mm to pass through, and there is no obvious flat water on the ground during movement, and the floor drying time is less than 1 minute.
[0017] Figure 5 Schematic diagram of the structure of the second scraper strip of the present invention. Figure 5 As shown, in addition to the first scraper bar 200 disposed on the front side of the roller brush 100, the floor cleaning device also includes a second scraper bar 300 on the rear side of the roller brush 100. The second scraper bar 300 is a straight strip, and a plurality of single-sided protrusions 301 are evenly spaced at the lower edge of one side of the free end of the second scraper bar 300. When the floor cleaning device is stationary on the surface to be worked, the second scraper bar 300 naturally droops and is perpendicular to the surface to be worked. Figure 3 , Figure 4 As shown, during the process of the floor cleaning device moving forward and backward, the second scraper strip 300 is lifted up by the single-sided convex point 301 to increase the air flow and improve the suction capacity.
[0018] Embodiment 2 Figure 6 , Figure 7 They are schematic diagrams of the position of the first scraper strip in the forward state of the second embodiment of the present invention; Figure 8 , Fig. 9 They are schematic diagrams of the position of the first scraper strip in the backward state of the second embodiment of the present invention. Figures 6 to 9 As shown, in this embodiment, the trigger component includes a detection unit, and the detection unit includes a transmitting end and a receiving end respectively arranged on the body of the floor cleaning device and the walking wheel. The execution component includes a second stepper motor 600 and a connecting rod mechanism connected thereto, and the connecting rod mechanism is connected to the first scraper 200. The detection unit detects the signal change between the transmitting end and the receiving end, outputs a signal and starts the second stepper motor 600, and the second stepper motor 600 drives the connecting rod mechanism to drive the first scraper 200 to flip. As needed, the detection unit can be implemented in a variety of forms, including an optical coupler sensor or a Hall sensor.
[0019] Specifically, the connecting rod mechanism includes a cam 710, a connecting rod 720 and a swing rod 730 connected in sequence. The cam 710 is connected to the second stepping motor 600. The outer edge of the cam 710 abuts against one end of the connecting rod 720. The other end of the connecting rod 720 is connected to one end of the swing rod 730. The other end of the swing rod 730 is connected to the first scraper 200. The two move synchronously in the same direction. A limiting groove 721 is provided on the connecting rod 720. A base boss 722 is provided on the body of the floor cleaning device. The reciprocating motion of the connecting rod 720 causes the limiting groove 721 to reciprocate relative to the base boss 722. In order to facilitate resetting, a reset spring 723 is also provided between the base boss 722 and the rear side of the groove wall of the limiting groove 721.
[0020] like Figures 6 to 9 As shown, in this embodiment, the working process of the control mechanism is as follows: like Figure 6 Combined with Figure 7 As shown, when the floor cleaning device is in the forward state, the second stepper motor 600 drives the cam 710 at the output end to rotate after receiving the signal from the host. The signal sent by the host is the signal sent by the floor cleaning device itself. Normally, the signal includes four states, namely forward, backward, turn and stop. However, in the working process of the control mechanism, only the forward and backward situations need to be considered. When the cam 170 rotates, it is equivalent to the eccentric setting of the output shaft with the cam 710 and the second stepper motor 600. The cam 710 drives the connecting rod 720 to move forward, and the cam 710 and the connecting rod 720 maintain abutting state. One end of the swing arm 730 fixes the first scraper strip 200, and the other end is rotatably connected to one end of the connecting rod 720, so that the first scraper strip 200 swings backward and is in an open state as shown in FIG. Figure 5 and Figure 6 shown.
[0021] When the floor cleaning device is in the backward state, the walking wheel 400 moves backward, and the second stepper motor 600 drives the cam 710 to continue to rotate after receiving the signal, so that the cam 710 is separated from the connecting rod 720, and the connecting rod 720 is quickly restored to the initial state under the action of the return spring 723. At this time, the first scraper strip 200 is in contact with the floor. Figure 8 and Fig. 9 shown.
[0022] Fig.10 FIG. 1 is a schematic diagram of the overall structure of the floor cleaning machine of the present invention. Fig.10 As shown, the present invention also provides a floor cleaning machine, which mainly includes a body 800, wherein the upper portion of the body 800 is connected to a handle 900, and the lower portion is connected to a floor cleaning device, and the floor cleaning device is the floor cleaning device as described above. Fig.10 The floor cleaning machine shown in the figure integrates washing, suction and instant drying, and at the same time adds the function of removing large particles from the floor without the need for pre-treatment, thus truly realizing the multi-purpose use of one machine.
[0023] The working process of the floor cleaning machine provided by the present invention is described as follows in combination with a specific working scenario: In the lobby of the hotel, the tile floor needs to be cleaned. The user turns on the whole machine switch 901 of the cleaning machine, the main motor and the brush motor start, and the first scraper 200 self-checks and returns to the starting position, that is, the flipped open position. The machine is pushed to the position to be cleaned at a uniform speed. The second scraper 300 is unilaterally attached to the ground and together with the roller brush, particles, water and other impurities are thrown into the air inlet through the roller brush. The first scraper 200 is retracted, and air is replenished and particles, water or debris of a certain height are allowed to pass through the air inlet into the recovery barrel 801. The recovery barrel 801 separates impurities from air, and the air is discharged out of the machine along the air duct of the main motor.
[0024] When the machine moves backward, the travel wheel 400 outputs a signal to the first stepper motor 530, which drives the first scraper 200 to the end position, that is, a position close to vertical with the ground. The residual sewage or debris on the ground is further scraped to the rear, and at the same time, the single-sided convex point 301 set on the second scraper 300 lifts the second scraper 200 to increase the flow rate and improve the suction capacity. Figure 5 As shown, the second scraper strip 300 is straight under normal circumstances, and the shape of its free edge is a straight line. However, during the running process, due to the existence of the single-sided convex point 301 structure, the portion of the edge of the free edge provided with the single-sided convex point 301 and the remaining portion are in different positions, and the shape of its free edge is S-shaped, that is, a wavy shape as shown in 5.
[0025] The whole process of one forward movement and one backward movement is a complete process. If there are stubborn substances on the ground, the water pump trigger 902 can be pressed to spray the water or mixed solution in the water bucket 802 onto the roller brush 100 through the nozzle. The water is evenly spread on the ground through the rotation of the roller brush 100 to remove dirt. If the expected effect cannot be achieved in one round, it can be repeated several times until it is satisfactory.
[0026] In addition to the above-mentioned scenarios, the floor cleaning device and cleaning machine provided by the present invention can also be used in other scenarios with larger areas to be cleaned, including homes, shopping malls, banks, etc., and can completely remove both light and heavy dirt.
[0027] Based on the above content, it can be seen that the present invention also provides a scraper bar control method for a floor cleaning device, wherein the floor cleaning device includes a walking wheel 400, a roller brush 100 and a control mechanism arranged thereon, and a first scraper bar 200 is provided on the front side of the roller brush. When the floor cleaning device moves forward, the first scraper bar rotates in a direction away from the surface to be cleaned under the control of the control mechanism, and a first angle is formed between the plane where the first scraper bar is located and the surface to be cleaned, and 0°<first angle<90°; when the floor cleaning device moves backward, the first scraper bar rotates in a direction close to the surface to be cleaned under the control of the control mechanism, so that the plane where the first scraper bar is located is perpendicular to the surface to be cleaned.
[0028] In summary, the present invention provides a floor cleaning device, a cleaning machine and a scraper bar control method, which solves the problem of low suction power of large particles through the front adaptive scraper bar, and at the same time can significantly improve the cleanliness of the floor in a cycle and shorten the drying time of the floor; without occupying too much space of the main body of the floor cleaning device, it greatly improves the user experience; the cleaning is thorough and efficient.
