Description

[0002] In the technical field related to floor scrubbers, the components that play a major role in the floor cleaning effect include: a roller brush, a scraper and a scraper bar, wherein the roller brush part rotates under the drive of the roller brush motor, and the roller brush bristles help the detergent to combine with the floor stains to achieve the cleaning and scrubbing functions, and the scraper bar located below is responsible for scraping off the water stains remaining on the roller brush, and the scraper part is used to contact the roller brush and scrape off the dirt on the surface of the roller brush as the roller brush rotates, thereby achieving floor cleaning through the cooperation of the three. However, as the roller brush wipes the floor and continuously rubs against the scraper bar, wear and tear will occur, resulting in a reduction in the diameter of the roller brush, thereby causing the scraper bar to be unable to effectively scrape off the dirt on the roller brush. At the same time, the reduction in the diameter of the roller brush causes the entire washing machine to move downward, resulting in more contact between the scraper bar and the ground, and greater friction between the scraper bar and the ground, making it difficult for the floor scrubber to move.

[0052] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "contacted", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] In the technical field related to floor scrubbers, as the roller brush rubs the ground and continuously rubs against the scraper, wear and tear will occur, causing the diameter of the roller brush to decrease. As a result, the scraper cannot effectively scrape off the dirt on the roller brush. At the same time, the reduction in the diameter of the roller brush causes the floor scrubber to move downward as a whole, resulting in more contact between the scraper bar and the ground. The friction between the scraper bar and the ground is greater, making it difficult for the floor scrubber to move.

[0054] Based on this technical problem, the following embodiments are proposed.

[0055] Embodiment 1

[0056] like Figure 1-2 As shown, this embodiment proposes a scraper blade linkage assembly for a floor scrubber. The floor scrubber is provided with a frame 5. The scraper blade linkage assembly includes:

[0057] A rolling brush member 1, wherein the rolling brush member 1 is rotatably disposed on the frame 5;

[0058] A scraper member 2, the scraper member 2 is rotatably arranged on the frame 5, and an elastic member 12 is arranged on the scraper member 2, one end of the elastic member 12 is connected to the scraper member 2, and the other end is connected to the frame 5, and the scraper member 2 is kept against the outer peripheral surface of the roller brush member 1 under the action of the elastic member 12;

[0059] A scraping condition 3, wherein the scraping condition 3 is rotatably arranged on the frame 5, and the scraping condition 3 abuts against the ground to scrape the ground;

[0060] A transmission mechanism 4, the transmission mechanism 4 comprises a first transmission unit and a second transmission unit in transmission cooperation, the first transmission unit is in transmission cooperation with the scraper member 2, and the second transmission unit is in transmission cooperation with the scraper member 3;

[0061] Among them, the scraper member 2, the scraping condition 3 and the transmission mechanism 4 are designed as follows: when the diameter of the roller brush member 1 is reduced, the scraper member 2 rotates under the action of the elastic member 12 and remains against the outer peripheral surface of the roller brush member 1, and drives the first transmission unit to rotate, the rotation of the first transmission unit drives the second transmission unit to rotate, and the rotation of the second transmission unit drives the scraping condition 3 to move upward at the contact end with the ground.

[0062] In this embodiment, if Figure 1-2 As shown, the scraper strip linkage assembly can be used in a floor scrubber, and the scraper strip linkage assembly includes a roller brush 1, a scraper 2, a scraping mechanism 3 and a transmission mechanism 4. The roller brush 1 is arranged on a frame 5 of the floor scrubber and can rotate relative to the frame 5. The roller brush 1 is the main tool for cleaning the floor in the floor scrubber. A roller brush motor 102 is arranged inside the roller brush 1. The roller brush motor 102 can drive the roller brush 1 to rotate to sweep and scrub the floor. The roller brush 1 is provided with roller brush hairs on the outer peripheral surface in contact with the floor. When the roller brush 1 rotates, the roller brush hairs can combine the detergent with the stains on the floor, thereby realizing the functions of sweeping and scrubbing the floor during the rotation of the roller brush 1.

[0063] The scraper member 2 is arranged on the frame 5 and can rotate relative to the frame 5. An elastic member 12 that can be compressed and deformed is arranged on the scraper member 2. One end of the elastic member 12 is connected to the scraper member 2, and the other end is connected to the frame 5. The elastic member 12 is in a compressed state in the working state, so it will generate forces in opposite directions on the frame 5 and the scraper member 2 respectively. The force generated by the elastic member 12 on the scraper member 2 can continuously push the scraper member 2 to rotate in the direction close to the roller brush member 1, so that the outer peripheral surfaces of the scraper member 2 and the roller brush member 1 can continuously abut against each other during the operation of the floor scrubber, thereby realizing the floating state of the scraper member 2. The scraper member 2 can be made of metal or plastic. Under the constant force provided by the elastic member 12 of the scraper member 2, it always keeps in contact with the outer peripheral surface of the roller brush member 1, thereby providing continuous and constant pressure to the roller brush member 1, squeezing out and scraping off the dirt and impurities on the roller brush hair. While facilitating collection, it can also prevent the dirt and impurities on the roller brush hair from entering the interior of the frame 5 to cause blockage and affect the operation of the floor scrubber.

[0064] The scraping condition 3 is arranged on the frame 5 and can rotate relative to the frame 5. The scraping condition 3 can scrape off the water stains remaining on the ground after the roller brush 1 is cleaned by contacting the ground. The scraping condition 3 can be composed of a combination of soft plastic and hard plastic. The hard plastic can fix the scraping condition 3 at the lower position of the frame 5. The soft plastic can continuously scrape off the water stains on the ground by contacting the ground, thereby ensuring the cleaning effect of the floor scrubber.

[0065] The first transmission unit and the second transmission unit in the transmission mechanism 4 can be matched with each other in transmission, and the scraper member 2 can drive the first transmission unit to rotate through the transmission match, and the second transmission unit can drive the scraper condition 3 to rotate through the transmission match. Specifically, the transmission match between the scraper member 2, the scraper condition 3 and the transmission mechanism 4 is as follows: when the diameter of the roller brush member 1 decreases due to wear and tear, the scraper member 2 rotates toward the roller brush member 1 under the continuous force of the elastic member 12, so that the scraper member 2 can always rest on the outer peripheral surface of the roller brush member 1, and at the same time, the scraper member 2 will drive the first transmission unit to rotate during the movement, and the rotation of the first transmission unit will drive the second transmission unit to rotate, and the second transmission unit will drive the scraper condition 3 to move during the rotation, so that the contact end of the scraper condition 3 with the ground moves upward.

[0066] Preferably, there are two groups of transmission mechanisms 4, and the two groups of transmission mechanisms 4 are respectively arranged on both sides of the scraper and scraper strip linkage assembly, so that the forces on the scraper member 2 and the scraper member 3 can be kept balanced, thereby making the operation of the scraper and scraper strip linkage assembly smoother.

[0067] Preferably, the scraping force of the scraper member 2 on the roller brush member 1 can be changed by adjusting the elastic coefficient of the elastic member 12 .

[0068] By arranging a roller brush member 1, a scraper member 2, a scraping condition 3 and a transmission mechanism 4 in the scraper and scraper bar linkage assembly, and by connecting and cooperating with each other, when the diameter of the roller brush member 1 of the floor scrubber becomes smaller, it can not only ensure a good effect of cleaning and collecting dirt and impurities, but also reduce the friction between the ground and the scraping condition 3 by maintaining the compression amount of the contact end of the scraping condition 3 with the ground consistent with the compression amount during initial use. While reducing the loss of the scraping condition 3, the scraping effect of the scraping condition 3 on dirt and impurities on the roller brush member 1 is also improved, thereby reducing the resistance faced by users during use and improving the use efficiency of the floor scrubber.

[0069] Optionally, in an implementation of this embodiment, as Figure 3-5 As shown,

[0070] The first transmission unit includes a first gear 401, and the first gear 401 is fixedly connected to the scraper member 2;

[0071] The second transmission unit includes a second gear A4021, a second gear B4022 and a connecting rod 403 which are meshed with each other. The second gear A4021 and the second gear B4022 are arranged from top to bottom along the height direction of the frame 5. The second gear A4021 and the second gear B4022 are both rotatably connected to the frame 5. The second gear A4021 is meshed with the first gear 401. One end of the connecting rod 403 is transmission connected to the second gear B4022, and the other end is rotatably connected to the scraping condition 3.

[0072] In this embodiment, Figure 3-5 As shown, the first transmission unit includes a first gear 401, which is fixedly connected to the scraper member 2. When the scraper member 2 rotates, the first gear 401 also rotates synchronously. The second transmission unit includes a second gear A4021 and a second gear B4022 that mesh with each other and a connecting rod 403. The second gear A4021 and the second gear B4022 are arranged from top to bottom along the height direction of the frame 5. The second gear A4021 is located above the second gear B4022. The second gear A4021 and the second gear B4022 are both rotatably connected to the frame 5. The second gear A4021 meshes with the first gear 401 and rotates in the opposite direction to the first gear 401. One end of the connecting rod 403 is fixedly connected to the axis of the second gear B4022, and the other end is rotatably connected to the scraper condition 3. When the second gear B4022 rotates, it can drive one end of the connecting rod 403 to rotate synchronously, thereby driving the other end of the connecting rod 403 to move, and then driving the scraper condition 3 to rotate.

[0073] Preferably, the second gear A4021 and the second gear B4022 are two completely identical gears, so that the transmission ratio of the second gear A4021 and the second gear B4022 can be the same, so that the force of the scraper member 2 on the roller brush member 1 and the compression of the scraping condition 3 on the ground can be kept consistent with the beginning.

[0074] Specifically, when the diameter of the roller brush member 1 becomes smaller, the scraper member 2 rotates toward the roller brush member 1 under the action of the elastic member 12, and drives the first gear 401 to rotate clockwise. At this time, the second gear A4021 rotates counterclockwise, and drives the second gear B4022 to rotate clockwise. At this time, the connecting rod 403 moves forward and pushes the scraping condition 3 to rotate clockwise. At this time, the scraping condition 3 moves upward along the height direction of the frame 5, and the compression amount of the scraping condition 3 in contact with the ground is reduced.

[0075] By arranging a plurality of gears and connecting rods 403 in the first transmission unit and the second transmission unit, the installation space occupied by the first transmission unit and the second transmission unit can be reduced, so as to reduce the volume of the frame 5, so that the floor scrubber can reduce the volume of the floor scrubber while reducing the user's use resistance, thereby making it more convenient and labor-saving for the user to move the floor scrubber.

[0076] Optionally, in an implementation of this embodiment, as Figure 6-9 As shown,

[0077] The first gear 401 is constructed as a half gear, and the connecting rod 403 includes a first connecting rod 403 and a second connecting rod 4032. One end of the first connecting rod 403 is fixedly connected to the axis of the second gear B4022, and the other end is rotatably connected to one end of the second connecting rod 4032. The other end of the second connecting rod 4032 is rotatably connected to the scraping condition 3.

[0078] In this embodiment, Figure 6-9 As shown, the first gear 401 is constructed as a half gear. Since the rotation range of the scraper member 2 limits the rotation range of the first gear 401, it is only necessary to set the gear teeth on the side of the first gear 401 close to the second gear A4021. The connecting rod 403 includes a first connecting rod 403 and a second connecting rod 4032. One end of the first connecting rod 403 is fixedly connected to the axis of the second gear B4022, and the other end is rotatably connected to one end of the second connecting rod 4032. The other end of the second connecting rod 4032 is rotatably connected to the scraping condition 3. When the second gear B4022 rotates clockwise, the other end of the first connecting rod 403 drives the second connecting rod 4032 to move toward the scraping condition 3, thereby pushing the scraping condition 3 to move upward along the height direction of the frame 5.

[0079] By setting the first connecting rod 403 and the second connecting rod 4032, the force generated by the clockwise rotation of the second gear B4022 can be converted into a force for moving upward along the height direction of the frame 5, so that the compression amount of the scraping condition 3 in contact with the ground is reduced, thereby making the compression amount of the scraping condition 3 in contact with the ground consistent with the compression amount during initial use, thereby reducing the resistance faced by the user during use.

[0080] Optionally, in an implementation of this embodiment, as Figure 6-9 As shown,

[0081] The elastic member 12 is constructed as a torsion spring, one protruding end of the torsion spring is connected to the scraper member 2 , and the other protruding end of the torsion spring is connected to the frame 5 .

[0082] In this embodiment, Figure 6-9 As shown, the elastic member 12 is constructed as a torsion spring, and one of the extended ends of the torsion spring is connected to the scraper member 2, and the other extended end is connected to the frame 5. Since the installation space required for the torsion spring is small, when the distance between the scraper member 2 and the frame 5 is close, the torsion spring can be arranged between the scraper member 2 and the frame 5 in a compressed state. Since the scraper member 2 can rotate relative to the frame 5, the torsion spring in a compressed state can continuously apply a force to the scraper member 2 in a direction away from the frame 5, so that the scraper member 2 can continuously abut against the outer peripheral surface of the roller brush member 1 without being affected by the change in the diameter of the roller brush member 1.

[0083] By using the torsion spring as the elastic member 12, the distance between the scraper member 2 and the frame 5 can be further shortened while ensuring that the scraper member 2 continues to abut against the outer peripheral surface of the roller brush member 1, thereby further reducing the volume of the frame 5 and making the overall floor scrubber more compact and lightweight.

[0084] Optionally, in an implementation of this embodiment, as Figure 6-9 As shown,

[0085] A water channel is formed inside the scraper member 2, and a water outlet 6 connected to the water channel is opened on a side wall of the scraper member 2 close to the roller brush member 1. The water outlet 6 is used to spray water to the outer peripheral surface of the roller brush member 1, and a water inlet 7 connected to the water channel is connected to a side wall away from the roller brush member 1.

[0086] In this embodiment, Figure 6-9As shown, a water channel is formed inside the scraper member 2, a water inlet 7 connected to the water channel is provided on a side wall of the scraper member 2 away from the roller brush member 1, and a water outlet 6 connected to the water channel is provided on a side wall of the scraper member 2 close to the roller brush member 1. When the floor scrubber is working, the water stored in the frame 5 is mixed with the detergent to form cleaning water, which flows from the water inlet 7 into the water channel inside the scraper member 2, and is sprayed onto the roller brush hair of the roller brush member 1 through the water outlet 6, so that the roller brush hair can always be soaked with cleaning water during operation, avoiding the user from manually soaking the roller brush hair, thereby improving the efficiency of the roller brush member 1 in cleaning and scrubbing the floor, and providing the user with a convenient and labor-saving use experience.

[0087] Optionally, in an implementation of this embodiment, as Figure 6-9 As shown,

[0088] The scraper member 2 includes a scraper body 201 , one end of the scraper body 201 away from the ground is rotatably connected to the frame 5 , and the other end close to the ground is provided with a first scraping end, which abuts against the outer peripheral surface of the roller brush member 1 .

[0089] In this embodiment, Figure 6-9 As shown, the scraper member 2 includes a scraper body 201, and the end of the scraper body 201 away from the ground is rotatably connected to the frame 5, so that the scraper member 2 can be rotated relative to the frame 5. A first scraping end is arranged at the end of the scraper body 201 close to the ground, so that the first scraping end is abutted against the outer peripheral surface of the roller brush member 1, and the scraper member 2 peels off and cleans the dirt and impurities attached to the outer peripheral surface of the roller brush member 1 through the first scraping end.

[0090] The scraper body 201 is rotatably connected to the frame 5 and the first scraping end abuts against the outer peripheral surface of the roller brush member 1, so that the scraper member 2 can be unaffected by the change in the diameter of the roller brush member 1 and can continue to clean the roller brush member 1.

[0091] Optionally, in an implementation of this embodiment, as Figure 6-9 As shown,

[0092] The first scraping end includes a scraping layer 202, a first sealing layer 203 and a fixing layer 204, wherein the first sealing layer 203 is located between the scraping layer 202 and the fixing layer 204, and the fixing layer 204 fixes the scraping layer 202 and the first sealing layer 203 on the scraper body 201 through a fixing member;

[0093] The scraping layer 202 abuts against the surface of the roller brush 1 , and the first sealing layer 203 seals between the frame 5 and the scraper body 201 to prevent dirt of the roller brush 1 from entering the frame 5 .

[0094] In this embodiment, Figure 6-9As shown, the first scraping end includes a scraping layer 202, a first sealing layer 203 and a fixed layer 204. The first sealing layer 203 is located between the scraping layer 202 and the fixed layer 204, and is used to prevent the dirt and impurities peeled off from the roller brush member 1 from moving upward into the frame 5. The fixed layer 204 fixes the scraping layer 202 and the first sealing layer 203 on the scraper body 201 through a fixing member, so that the first scraping end can move synchronously with the scraper body 201. The scraping layer 202 abuts against the outer peripheral surface of the roller brush member 1 so as to clean the roller brush hair when the roller brush member 1 rotates. The end of the first sealing layer 203 away from the scraper body 201 is inclined and extends toward the ground to form a plate-shaped shielding structure, which can form a seal between the frame 5 and the scraper body 201, thereby preventing the dirt and impurities peeled off from the roller brush member 1 from entering the frame 5.

[0095] Preferably, the fixing member may be a screw, which passes through the fixing layer 204 , the first sealing layer 203 and the scraping layer 202 in sequence and is then threadedly connected to the scraper body 201 .

[0096] Preferably, the fixing member may be a plurality of waterproof adhesive members, which sequentially bond the fixing layer 204 , the first sealing layer 203 and the scraping layer 202 together, and bond the fixing layer 204 to the scraper body 201 .

[0097] By providing the scraping layer 202, the first sealing layer 203 and the fixing layer 204, the first scraping end can continuously clean the roller brush 1 while preventing dirt and impurities peeled off from the roller brush 1 from entering the frame 5, thereby further improving the working efficiency of the floor scrubber.

[0098] Optionally, in an implementation of this embodiment, as Figure 10-11 As shown,

[0099] The scraping element 3 comprises a scraping strip body 301 , the upper end of which is rotatably connected to the frame 5 , and the lower end of which is provided with a second scraping end 302 , which contacts the ground.

[0100] In this embodiment, Figure 10-11 As shown, the scraping condition 3 includes a scraping strip body 301, and the upper end of the scraping strip body 301 is rotatably connected to the frame 5, thereby enabling the scraping condition 3 to rotate relative to the frame 5, and a second scraping end 302 is arranged at the lower end of the scraping strip body 301, so that the second scraping end 302 is in contact with the ground, thereby enabling the scraping condition 3 to continuously scrape water stains on the ground.

[0101] By setting the scraper strip body 301 and the second scraper end 302, the scraper element 3 can keep the compression amount of its contact end with the ground consistent with the compression amount during initial use after the diameter of the roller brush 1 becomes smaller, thereby ensuring the cleaning effect of the floor scrubber while providing the user with a convenient and labor-saving use experience.

[0102] Optionally, in an implementation of this embodiment, as Figure 10-11 As shown,

[0103] A connecting plate 303 is provided on the scraper body 301, and the second connecting rod 4032 is rotatably connected to the connecting plate 303;

[0105] In this embodiment, Figure 10-11 As shown, a connecting plate 303 is provided on the scraper body 301, and the second connecting rod 4032 is rotatably connected to the connecting plate 303, so that the scraper end 3 is driven to rotate by the forward and backward movement of the second connecting rod 4032. Grooves or through holes are symmetrically provided at both ends of the scraper body 301, so that the scraper body 301 is rotatably connected to the frame 5 through the connecting member. A second sealing layer 304 is provided on the scraper body 301, and the second sealing layer 304 is located between the frame 5 and the scraper body 301, and is used to prevent the sewage splashed by the second scraping end 302 when cleaning water stains from entering the inside of the frame 5.

[0106] Preferably, the second sealing layer 304 is made of soft plastic and is fixed on the scraper strip body 301 by an injection molding process.

[0107] Preferably, one end of the second sealing layer 304 close to the second connecting rod 4032 extends toward the connecting plate 303 to form a curved sealing end, which is located at the gap between the scraper body 301 and the frame 5. The curved sealing end is a hollow structure, and its function is to achieve extrusion sealing with the frame 5 in different directions when the scraper 3 rotates, so that the gap between the scraper 3 and the frame 5 is always kept in a sealed state, thereby further preventing the sewage splashed by the second scraper end 302 when cleaning water stains from entering the inside of the frame 5.

[0108] By providing a second sealing layer 304 on the scraper body 301, the scraper 3 can continuously clean the water stains on the ground while preventing the dirty water splashed from the second scraping end 302 when removing the water stains from entering the frame 5, thereby further improving the working efficiency of the floor scrubber.

[0109] Optionally, in an implementation of this embodiment, as Figure 10-11 As shown,

[0111] In this embodiment, Figure 10-11 As shown, the scraper body 301 is made of a hard part, and the scraper body 301 is mainly used to connect the second scraping end 302 and the second connecting rod 4032, and the second scraping end 302 is driven to rotate by the second connecting rod 4032. Therefore, the use of a hard part can ensure the rigidity of the scraper body 301, making the overall structure of the scraper 3 more stable. The second scraper end 302 is made of a soft part, and the second scraper end 302 mainly scrapes the water stains on the ground through the friction force generated by its compression deformation. Therefore, the use of a soft part can ensure that the contact area between the second scraper end 302 and the ground is large enough, so that the scraper 3 can clean the residual water stains on the ground more thoroughly.

[0112] Preferably, the soft part can be soft plastic, which can ensure good contact with the ground and compensate for errors, thereby scraping water stains on the ground. The hard part can be hard plastic, which can support the second scraping end 302 and the second sealing layer 304.

[0124] In this embodiment, Figure 1 As shown, the floor scrubber includes a frame 5, on which a water tank 9, a water pump 10 and a scraper blade linkage assembly as in the above-mentioned embodiment 1 are arranged. The scraper blade linkage assembly is arranged inside the frame 5, wherein the inflow end of the water pump 10 is connected to the water tank 9, and the outflow end of the water pump 10 is connected to the waterway, so that the cleaning water can be continuously sprayed onto the roller brush 1.

[0125] Preferably, the floor scrubber is also provided with a control panel, which obtains data through the controller 13 and multiple sensors connected to various components of the floor scrubber. The controller 13 can judge various indicators of the floor scrubber. The user can adjust the cleaning mode of the floor scrubber, the amount of water added to the water tank 9, the storage status of the dirt box, etc. through the control panel. The cleaning mode includes dry cleaning mode and wet cleaning mode.

[0126] By providing a water tank 9 and a water pump 10, the floor scrubber can store and carry water. Adding detergent into the water tank 9 can form cleaning water. The water pump 10 can spray the cleaning water from the waterway to the roller brush bristles of the roller brush member 1, so that the roller brush bristles can always be soaked with cleaning water during operation, avoiding the user's manual soaking of the roller brush bristles, thereby improving the efficiency of the roller brush member 1 in cleaning and scrubbing the floor, and providing the user with a convenient and labor-saving use experience.

[0127] Optionally, in an implementation of this embodiment, as Figure 1 As shown, the frame 5 is provided with a dirt box, a suction pump and a dirt suction port 11;

[0128] The inflow end of the suction pump is connected to the sewage suction port 11 , and the outflow end of the suction pump is connected to the dirt box. The sewage suction port 11 is used to absorb the dirt on the scraping condition 3 .

[0129] In this embodiment, Figure 1 As shown, a dirt box, a suction pump and a dirt suction port 11 are respectively arranged on the frame 5, and the inflow end of the suction pump is connected to the dirt suction port 11. The dirt suction port 11 is located at one end of the first sealing layer 203 away from the scraper body 201 and in the middle of the first sealing layer 203. When the roller brush 1 rotates to clean the ground, the dirt and impurities can be peeled off from the roller brush 1 under the action of the rotating centrifugal force and the scraper 2, and thrown to the dirt suction port 11 together with the water stains remaining on the ground.

[0130] By connecting the outflow end of the suction pump with the dirt box, the dirt suction port 11, the suction pump and the dirt box are connected in sequence, and the dirt impurities peeled off from the roller brush 1 and the water stains remaining on the ground can be sucked into the dirt box through the dirt suction port 11 for collection, avoiding the user from frequently cleaning the dirt impurities and the water stains remaining on the ground, thereby extending the single working time of the floor scrubber, thereby improving the working efficiency of the floor scrubber and enhancing the user experience.

[0134] This embodiment provides a sweeping machine, including:

[0135] Such as the scraper blade linkage assembly in the above-mentioned embodiment 1.

[0136] In this example, the sweeping machine includes the scraper and scraper linkage assembly as in the above-mentioned embodiment 1. Since the sweeping machine includes the scraper and scraper linkage assembly as in the above-mentioned embodiment 1, the sweeping machine has all the beneficial effects of the scraper and scraper linkage assembly as in the above-mentioned embodiment 1, which will not be repeated here.

[0137] In summary, the ingenious design of the scraper and scraper linkage assembly is:

[0138] First, by arranging a roller brush part, a scraper part, a scraping condition and a transmission mechanism in the scraper and scraper bar linkage assembly, and by connecting and cooperating the above-mentioned parts with each other, when the diameter of the roller brush part of the floor scrubber becomes smaller, it can not only ensure a good effect of cleaning and collecting dirt and impurities, but also reduce the friction between the ground and the scraping condition by maintaining the compression amount of the scraping condition at the contact end with the ground consistent with the compression amount at the initial use. While reducing the loss of the scraping condition, it also improves the scraping effect of the scraping condition on the dirt and impurities on the roller brush part, thereby reducing the resistance faced by users during use and improving the use efficiency of the floor scrubber.

[0139] Second, by arranging a plurality of gears and connecting rods in the first transmission unit and the second transmission unit, the installation space occupied by the first transmission unit and the second transmission unit can be reduced, thereby reducing the volume of the frame, so that the floor scrubber can reduce the volume of the floor scrubber while reducing the user's use resistance, thereby making it more convenient and labor-saving for the user to move the floor scrubber.

[0140] Third, by setting the first connecting rod and the second connecting rod, the force generated by the clockwise rotation of the second gear B can be converted into a force for moving upward along the height direction of the frame, thereby reducing the compression amount of the scraping condition contact end with the ground, thereby achieving the goal of making the compression amount of the scraping condition contact end with the ground consistent with the compression amount during initial use, thereby reducing the resistance faced by users during use.

[0141] Fourth, by providing the scraping layer, the first sealing layer and the fixing layer, the first scraping end can continuously clean the roller brush while preventing dirt and impurities peeled off the roller brush from entering the frame, thereby further improving the working efficiency of the floor scrubber.

[0142] Fifth, by setting up a water tank and a water pump, the floor scrubber can store and carry water. Adding detergent into the water tank can form cleaning water. The water pump can spray the cleaning water from the waterway to the roller brush bristles of the roller brush, so that the roller brush bristles can always be soaked with cleaning water during operation, avoiding the user's manual soaking of the roller brush bristles, thereby improving the efficiency of the roller brush for cleaning and scrubbing the floor, and providing users with a convenient and labor-saving experience.
