Description

Technical Field

[0001] The present invention belongs to the technical field of cleaning equipment, and more particularly, relates to a scraper bar assembly and a floor scrubber. Background Art

[0002] A floor scrubber is a common type of floor cleaning equipment. It scrubs the floor with a roller brush and then uses a water suction component to collect the wastewater generated after scrubbing into a wastewater tank inside the machine, preventing it from spreading on the floor and completing the floor cleaning process. Due to the limited suction power of the water suction component, a scraper is generally required to scrape and guide the wastewater toward the suction port during the water suction process, thereby improving water suction efficiency and preventing excess water stains on the floor.

[0003] In related technologies, floor scrubbers typically use a scraping bar structure that lies close to the ground, scraping water to the water inlet. A water suction component, such as a fan, then draws the wastewater in. However, in actual use, the scraping bar's effectiveness is limited, often resulting in a high residual water rate. This is especially true when the pump output is slightly higher, where residual water on the ground becomes more severe, making it difficult to guarantee a good floor scrubbing effect. Summary of the Invention

[0004] The main purpose of the embodiments of the present invention is to provide a scraper bar assembly and a floor scrubber to solve the technical problems in the prior art of floor scrubbers, such as poor scraping effect, high residual water rate on the ground, and difficulty in improving the floor scrubbing effect.

[0005] The technical solution adopted by the present invention is: to provide a scraper strip assembly, including a support frame, and a first scraper strip and a second scraper strip installed on the support frame, the end of the first scraper strip away from the support frame forms a first functional end, the first functional end is used to abut against the ground, the end of the second scraper strip away from the support frame forms a second functional end, the second functional end is spaced apart from the first functional end and is located on the same side of the support frame, and the second functional end is used to be spaced apart from the ground.

[0006] In some embodiments, along the length direction, the first functional end is parallel to the second functional end.

[0007] In some embodiments, the first functional end and the second functional end are both arc-shaped, and the first functional end is bent away from the second functional end, and the second functional end is bent away from the first functional end.

[0008] In some embodiments, the support frame is provided with a first slot and a second slot along the length direction, the first scraper strip is plugged into the first slot, and the second scraper strip is plugged into the second slot.

[0009] In some embodiments, the first scraper strip has a first connecting end adapted to be plugged into the first slot, two opposite side walls of the first connecting end have first grooves, and two side walls of the first slot have first latching protrusions adapted to be latched into the first grooves.

[0010] In some embodiments, the second scraper strip has a second functional end adapted to be plugged into the second slot, the opposite side walls of the second connection end have second grooves, and the side walls of the second slot have second latching protrusions adapted to be latched into the second grooves.

[0011] In some embodiments, a magnetic component is further provided on the support frame, and the magnetic component is used for magnetic adsorption connection with the floor scrubber body.

[0012] The above-mentioned one or more technical solutions in the scraper bar assembly provided by the embodiment of the present invention have at least one of the following technical effects: a first scraper bar is mounted on the support frame, and the end of the first scraper bar facing away from the support frame forms a first functional end for contacting the ground. When in use, the first scraper bar is spaced apart from the roller brush of the floor scrubber. When recovering wastewater, the suction assembly inside the floor scrubber draws air between the first scraper bar and the roller brush, thereby forming a negative pressure space between the first scraper bar and the roller brush. Wastewater is sucked in under the action of the suction power of the suction assembly and atmospheric pressure, thereby improving wastewater suction efficiency. At the same time, a second scraper bar is mounted on the support frame, and the end of the second scraper bar facing away from the support frame is spaced apart from the first functional end to form a second functional end. When in actual use, the second functional end is positioned between the first functional end and the roller brush, and the second functional end is spaced apart from the ground by design. The second functional end can scrape away wastewater from the ground, making it easier for the suction assembly to inhale it. In this way, the first functional end of the first scraper and the second functional end of the second scraper cooperate with each other to improve the efficiency of the floor scrubber in recycling wastewater, reduce the residual water rate on the ground, reduce water marks, and effectively improve the floor scrubbing effect and efficiency of the floor scrubber.

[0013] Another technical solution of the present invention is to provide a floor scrubber, comprising a floor scrubber body and the above-mentioned scraper bar assembly, the scraper bar assembly being connected to the floor scrubber body, the floor scrubber body being provided with a water suction port, the first functional end being spaced apart from the water suction port, and the second functional end being provided on the side of the water suction port.

[0014] In some embodiments, the scraper bar assembly is detachably connected to the floor scrubber body.

[0015] In some embodiments, a magnetic component is provided on the support frame, and a magnetic connecting portion is provided on the floor scrubber body, and the magnetic component is connected to the magnetic connecting portion by magnetic adsorption.

[0016] The above one or more technical solutions in the floor scrubber provided by the embodiment of the present invention have at least one of the following technical effects: by using the above scraper bar assembly, when the floor scrubber recycles wastewater, a negative pressure space can be formed between the first functional end of the first scraper bar and the roller brush, so that the wastewater is sucked in under the suction power of the suction assembly and the atmospheric pressure, thereby improving the water absorption efficiency. At the same time, the second functional end of the second scraper bar can also play the role of scraping and driving away water. The second functional end scrapes up the wastewater on the ground, making it easier for the suction assembly to suck it in. The first scraper bar and the second scraper bar of the scraper bar assembly cooperate with each other, effectively improving the efficiency of the floor scrubber in recycling wastewater. After the floor scrubber is cleaned, the residual water rate on the ground is reduced and the water marks are reduced, thereby effectively improving the floor scrubbing effect and efficiency of the floor scrubber and improving the user experience.

[0037] like Figures 1 to 6 As shown, an embodiment of the present invention provides a scraper bar assembly suitable for installation in a floor scrubber. When the floor scrubber is started, the scraper bar assembly is used to scrape and guide wastewater generated by floor scrubbing to the water intake of the floor scrubber, thereby recycling the wastewater generated by floor scrubbing into a wastewater tank within the floor scrubber. The floor scrubber may be a floor scrubber robot, a mopping robot, a washing and mopping robot, a handheld floor scrubber, or a ride-on floor scrubber.

[0038] The scraper strip assembly 10 of the present application is described in detail below with reference to specific embodiments.

[0039] See also Figures 1 to 5 ,in, Figure 1 This is a schematic structural diagram of a scraper strip assembly provided in one embodiment of the present invention. Figure 2 for Figure 1 The exploded view of the scraper assembly shown is Figure 3 For the Figure 1 The sectional view of the AA line, Figure 4 for Figure 1 The cutaway view of the scraper bar assembly shown is when it is installed on the main body of the scrubber. Figure 5 for Figure 1 The diagram shown is a schematic diagram of the flow direction of sewage when the scraper bar assembly is installed on the main body of the floor scrubber.

[0040] In this embodiment, if Figures 1 to 3 As shown, the scraper assembly 10 of this embodiment includes a support frame 11, which is used to connect with the floor scrubber body 20, for example, it can be connected integrally or detachably, such as screwed or clamped, etc. Figure 4 The scraper assembly 10 further includes a first scraper 12 and a second scraper 13, both of which are mounted on the support frame 11. Specifically, the first scraper 12 and the second scraper 13 can be integrally formed with the support frame 11, or can be detachably mounted separately from the support frame 11.

[0041] In this embodiment, if Figure 3 and Figure 4 As shown, the end of the first scraper 12 away from the support frame 11 forms a first functional end 121. When the scraper assembly 10 is connected to the floor scrubber body 20, the first functional end 121 is used to contact the floor to be cleaned (such as Figure 4 The second scraper bar 13 abuts against the plane shown in G in the figure, and the end of the second scraper bar 13 facing away from the support frame 11 forms a second functional end 131. The second functional end 131 and the first functional end 121 are located on the same side of the support frame 11, and the two are spaced apart. When the scraper bar assembly 10 is connected to the floor scrubber body 20, the second functional end 131 is used to be spaced apart from the ground.

[0042] In this way, when actually using Figure 4 and Figure 5 As shown, the support frame 11 of the scraper bar assembly 10 of the present application is connected to the scrubber body 20, and the first scraper bar 12 is arranged at intervals on the side of the roller brush 21 of the scrubber body 20, and the first scraper bar 12 is roughly parallel to the axis of the roller brush 21, and the second functional end 131 of the second scraper bar 13 and the first functional end 121 of the first scraper bar 12 are located on the same side of the support frame 11, so that the second functional end 131 is located between the first functional end 121 and the roller brush 21, and a water gap 211 is formed between the second scraper bar 13 and the outer wall surface of the roller brush 21, and a water intake port 22 connected to the water intake gap 211 is provided on the side of the roller brush 21, so that waste water on the ground can be sucked into the water intake port 22 through the water intake gap 211.

[0043] In this way, when the floor scrubber recycles waste water, the suction component (not shown) inside the floor scrubber body 20, such as a fan component, sucks the air between the first scraper bar 12 and the roller brush 21, forming a negative pressure space between the first scraper bar 12 and the roller brush 21, so that the waste water can be sucked along the roller brush 21 under the action of the suction power of the suction component and the atmospheric pressure. Figure 5 The flow direction indicated by the dotted arrow is quickly sucked into the washing machine body 20, and the water absorption efficiency and water absorption capacity are improved when the waste water is recovered; in addition, the second functional end 131 of the second scraper 13 is spaced from the ground and can be moved along the moving direction of the washing machine body 20 (such as Figure 4 The waste water is scraped up in the direction indicated by the middle arrow F), thereby increasing the water level of the waste water at the roller brush 21, guiding the waste water to be recovered faster, further improving the waste water recovery efficiency, reducing the residual water rate on the ground, and avoiding residual water marks on the ground.

[0044] The scraper assembly 10 of the embodiment of the present invention is configured such that a first scraper 12 is installed on a support frame 11, and the end of the first scraper 12 facing away from the support frame 11 forms a first functional end 121 for abutting the ground. When in use, the first scraper 12 is spaced apart from the roller brush 21 of the floor scrubber body 20. When waste water is recovered, the suction assembly inside the floor scrubber sucks the air between the first scraper 12 and the roller brush 21, thereby forming a negative pressure space between the first scraper 12 and the roller brush 21. The waste water is sucked in under the action of the suction power of the suction assembly and the atmospheric pressure, thereby improving the waste water suction efficiency. At the same time, a second scraper bar 13 is provided on the support frame 11. The end of the second scraper bar 13 facing away from the support frame 11 is spaced apart from the first functional end 121 to form a second functional end 131. In actual use, the second functional end 131 is positioned between the first functional end 121 and the roller brush 21. The second functional end 131 is spaced apart from the ground so as to scrape away water. The second functional end 131 scrapes waste water from the ground, making it easier for the suction component to draw it in. In this way, the first functional end 121 of the first scraper bar 12 and the second functional end 131 of the second scraper bar 13 cooperate with each other to improve the efficiency of the floor scrubber in recovering waste water, reduce the residual water rate on the ground, and reduce water marks, thereby effectively improving the floor scrubbing effect and efficiency of the floor scrubber.

[0045] In this embodiment, if Figure 4 and Figure 5 As shown, since the setting of the first functional end 121 can raise the water level at the roller brush 21, at this time, for the second functional end 131, it is only used to scrape and drive away water. On the basis of ensuring the wastewater recovery efficiency, the second functional end 131 does not contact the ground, which can reduce the resistance to the movement of the floor scrubber body 20 and reduce energy consumption. At the same time, the second functional end 131 does not rub against the ground, and has a longer service life.

[0046] In another embodiment of the present invention, Figure 1 and Figure 4 As shown, along the length direction, the first functional end 121 is parallel to the second functional end 131. Thus, when the scraper bar assembly 10 of this embodiment is installed on the floor scrubber body 20, the first and second functional ends 121, 131, and the axis of the roller brush 21 remain parallel, fully utilizing the scraping and water-dispelling functions of the first and second functional ends 121, 131, accelerating the movement of wastewater toward the roller brush 21, thereby accelerating wastewater recovery. Furthermore, in this embodiment, along the length direction, the end surface of the first functional end 121 is a smooth, straight line, ensuring that its entire end surface effectively contacts the floor.

[0047] It can be understood that in this embodiment, the first functional end 121 being parallel to the second functional end 131 means that the first functional end 121 and the second functional end 131 can be kept substantially parallel under the condition that design and processing errors are allowed.

[0048] In another embodiment of the present invention, Figure 1 、 Figure 3 and Figure 5 As shown, both the first functional end 121 and the second functional end 131 are arc-shaped, with the first functional end 121 bending away from the second functional end 131, and the second functional end 131 bending away from the first functional end 121. That is, when the scraper bar assembly 10 of this embodiment is connected to the scrubber body 20, the first functional end 121 bends and extends away from the roller brush 21, while the second functional end 131 bends and extends toward the roller brush 21. At this time, when the scrubber body 20 moves forward, a portion of the first functional end 121 can adhere to the ground along the direction of movement, ensuring a higher degree of contact between the first functional end 121 and the ground. The second functional end 131 is bent and extended toward the roller brush 21, so that the second functional end 131 can better scrape water toward the roller brush 21, thereby improving the wiping and water-repelling effect of the second functional end 131.

[0049] In another embodiment of the present invention, Figures 1 to 3 As shown, the support frame 11 is provided with a first slot 111 and a second slot 112 along the length direction, the first scraper 12 is plugged into the first slot 111, and the second scraper 13 is plugged into the second slot 112, that is, the first scraper 12 and the second scraper 13 are plug-connected to the support frame 11, and the scraper assembly 10 is simple to assemble and plug-connected, which is convenient for replacing the scraper and has strong practicality.

[0050] Furthermore, in this embodiment, Figures 1 to 3 As shown, the first scraper strip 12 is provided with a first connection end 122 away from the first functional end 121, and the first connection end 122 is adapted to be plugged into the first slot 111. The second scraper strip 13 is provided with a second connection end 132 away from the second functional end 131, and the second connection end 132 is adapted to be plugged into the second slot 112. When assembling the scraper strip assembly 10 of this embodiment, the first connection end 122 is aligned with the first slot 111 and inserted to connect the support frame 11 and the first scraper strip 12. The second connection end 132 is aligned with the second slot 112 and inserted to connect the support frame 11 and the second scraper strip 13. The assembly operation is simple and the disassembly is convenient.

[0051] For example, in a specific embodiment, Figure 1 and Figure 3As shown, the first scraper 12 and the second scraper 13 are made of soft rubber. When installing the first scraper 12 and the second scraper 13, since both scrapers are made of soft rubber, the first connecting end 122 passes through the notch of the first slot 111 and the second connecting end 132 passes through the notch of the second slot 112. The connecting portion itself deforms and shrinks to enter the corresponding slot. After entering the slot, the connecting portion has a tendency to return to its original shape, which allows the first connecting end 122 (the second connecting end 132) to expand and achieve a fixed connection with the first slot 111 (the second slot 112), ensuring that the first scraper 12 and the second scraper 13 can be stably and reliably connected to the support bar. When the first scraper 12 or the second scraper 13 is needed, the corresponding scraper can be pulled out with force. The first scraper 12 and the second scraper 13 can be installed and removed quickly, making assembly and disassembly very convenient.

[0052] In some specific embodiments, Figure 2 and Figure 3 As shown, first grooves 1221 are defined on opposite sides of the first connection end 122 of the first scraper strip 12, and first latching protrusions 113 are defined on opposite sides of the first insertion slot 111 to engage with the first grooves 1221. When the first connection end 122 is inserted into the first insertion slot 111, the first latching protrusions 113 are latched into the first grooves 1221. Similarly, second grooves 1321 are defined on opposite sides of the second connection end 132 of the second scraper strip 13, and second latching protrusions 114 are defined on opposite sides of the second insertion slot 112 to engage with the second grooves 1321. When the second connection end 132 is inserted into the second insertion slot 112, the second latching protrusions 114 are latched into the second grooves 1321. In this way, the first latching protrusion 113 is provided to cooperate with the first groove 1221 to further limit the movement of the first scraper 12 relative to the support frame 11, so as to improve the connection reliability of the first scraper 12 and the support frame 11, and the second latching protrusion 114 is provided to cooperate with the second groove 1321 to further limit the movement of the second scraper 13 relative to the support frame 11, so as to improve the connection reliability of the second scraper 13 and the support frame 11.

[0053] In another embodiment of the present invention, please refer to Figure 6 ,in, Figure 6 for Figure 1 The diagram shows the assembly relationship between the scraper bar assembly 10 and the magnetic connection portion 23 of the floor scrubber body 20 .

[0054] like Figure 2 、 Figure 5 and Figure 6As shown, in this embodiment, a magnetic member 115 is further provided on the support frame 11 of the scraper bar assembly 10. The magnetic member 115 is used to magnetically connect to the scrubber body 20. Specifically, a magnetic connection portion 23 can be provided on the scrubber body 20, and the magnetic member 115 on the support frame 11 can be magnetically attached to the magnetic connection portion 23, thereby connecting the support frame 11 to the scrubber body 20. In this way, by providing the magnetic member 115 to magnetically connect the support frame 11 and the scrubber body 20, the scraper bar assembly 10 of this embodiment can be detachably connected to the scrubber body 20. The scraper bar assembly 10 is easy to assemble and disassemble. Compared with fasteners connected using screws, the magnetically connected scraper bar assembly 10 does not require the scrubber body 20 to be turned over during assembly and disassembly, which saves time and effort, and has relatively less impact on the structure of the scrubber body 20.

[0055] In a specific embodiment, Figure 2 、 Figure 5 and Figure 6 As shown, the above-mentioned magnetic part 115 can be a metal part, such as iron sheet or iron bar, etc. The magnetic part 115 can be integrally provided on the support frame 11, or can be fastened to the support frame 11 by fasteners such as screws. The magnetic connection part 23 of the floor scrubber body 20 is provided with a magnet 231, and the magnet 231 magnetically attracts the metal magnetic part 115, thereby realizing the connection between the support frame 11 and the floor scrubber body 20.

[0056] In this embodiment, if Figure 5 and Figure 6 As shown, the support frame 11 is connected with a plurality of magnetic parts 115 at intervals in the extension direction, and an embedding groove 232 is provided on the magnetic connection part 23 of the floor scrubber body 20 at the position corresponding to each magnetic part 115, and a magnet 231 is embedded in the embedding groove 232, thereby forming a connection with the floor scrubber body 20 in the length direction of the support frame 11, and the connection stability is better and the reliability is higher.

[0057] The scraper bar assembly 10 of the above-mentioned embodiments of the present invention, by installing the first scraper bar 12 and the second scraper bar 13 on the support frame 11. When the scraper bar assembly 10 is installed on the floor scrubber body 20, the first functional end 121 of the first scraper bar 12 and the second functional end 131 of the second scraper bar 13 cooperate with each other, which can improve the efficiency of the floor scrubber in recycling wastewater, reduce the residual water rate on the ground, and reduce water marks, thereby improving the floor scrubbing effect and efficiency of the floor scrubber.

[0058] Another embodiment of the present invention further provides a floor scrubber, such as Figure 4 and Figure 5As shown, the floor scrubber includes a floor scrubber body 20 and the scraper bar assembly 10 of each of the above-mentioned embodiments. The scraper bar assembly 10 is connected to the floor scrubber body 20. The floor scrubber body 20 is provided with a water suction port 22. The first functional end 121 is spaced apart from the water suction port 22, and the second functional end 131 is provided on the side of the water suction port 22.

[0059] Specifically, if Figure 5 As shown, the first scraper 12 is arranged at intervals on the side of the roller brush 21, and the first scraper 12 is roughly parallel to the axis of the roller brush 21. The second scraper 13 is arranged between the first scraper 12 and the roller brush 21. A water gap 211 is formed between the second scraper 13 and the outer wall of the roller brush 21. The water suction port 22 is arranged on the side of the roller brush 21 and is connected to the water gap 211, so that waste water on the ground can enter the water suction port 22 through the water gap 211.

[0060] The floor scrubber of the present application, by using the above-mentioned scraper bar assembly 10, can form a negative pressure space between the first functional end 121 of the first scraper bar 12 and the roller brush 21 when recycling wastewater, so that the wastewater is sucked in under the action of the suction power of the suction assembly and atmospheric pressure, and the water absorption efficiency is improved. At the same time, the second functional end 131 of the second scraper bar 13 can also play the role of scraping and driving away water. The second functional end 131 scrapes the wastewater on the ground, making it easier to be sucked in by the suction assembly. The first scraper bar 12 and the second scraper bar 13 of the scraper bar assembly 10 cooperate with each other, effectively improving the efficiency of the floor scrubber in recycling wastewater. After the floor scrubber is cleaned, the residual water rate on the ground is reduced and the water marks are reduced, thereby effectively improving the floor scrubbing effect and efficiency of the floor scrubber, and improving the user experience. In addition, the floor scrubber also has other technical effects of the scraper bar assembly 10 provided in the above-mentioned embodiments, which will not be repeated here.

[0061] In a specific embodiment, the above-mentioned floor scrubber may be a floor scrubber robot, a floor mopping robot, an all-in-one floor scrubber and mop robot, a handheld floor scrubber, a ride-on floor scrubber, or the like.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
