Description

Technical Field

[0001] The present invention relates to the technical field of floor cleaning equipment, and in particular to a floor scrubber. Background Art

[0002] A floor scrubber is a device that is pushed along the ground by the user to clean the floor. To clean the floor, a floor scrubber typically includes a roller brush assembly, a cleaning fluid tank, a suction unit, a water suction component, and a waste liquid recovery tank. The floor scrubber sprays cleaning fluid from the cleaning fluid tank onto the floor. The roller brush assembly then rotates, contacting the ground and sweeping up dust. The water suction component then delivers the swept-up dust and waste liquid to the waste liquid recovery tank, thereby cleaning the floor.

[0003] After long-term use of the floor scrubber, the rotation of the roller brush will throw garbage onto the mounting frame facing the roller brush, causing garbage to accumulate on the mounting frame and a poor user experience. Summary of the Invention

[0004] In order to solve at least one problem existing in the above-mentioned prior art, according to one aspect of the present invention, a cleaning device is provided for cleaning a roller brush, comprising: a pressurizing system, including a pressurizing pump and at least one water outlet pipe, the pressurizing pump is used to pressurize the water body, and the water outlet pipe is used to deliver the water body pressurized by the pressurizing pump; a roller brush, used to clean the floor; a mounting frame, used to clean the roller brush and connected to the water outlet pipe, the mounting frame has at least one spray port on the side facing the roller brush, and the spray port is used to discharge the high-pressure water body delivered through the water outlet pipe to rinse the surface of the mounting frame.

[0005] In this way, a pressurizing system is provided to pressurize the water body, and then the high-pressure water body is sprayed out through the spray port of the mounting frame, so that the high-pressure water body can clean the surface of the mounting frame. Since the high-pressure water body can generate a large impact force on the surface of the mounting frame, the garbage adhered to the surface of the mounting frame is washed away, so that the surface of the mounting frame can be kept clean, thereby improving the user experience.

[0006] In some embodiments, the mounting frame includes a main body and a protrusion provided on the main body, the protrusion protrudes toward the roller brush, a first water storage chamber is formed in the protrusion, and the spray port is provided on the protrusion and is connected to the first water storage chamber.

[0007] In this way, by setting up a water storage chamber, the water outlet pipe can introduce high-pressure water into the water storage chamber, and the high-pressure water can flow in the water storage chamber, which is convenient for setting up multiple spray outlets in the protrusion. Multiple spray outlets can all flow out high-pressure water, thereby covering a larger area to be cleaned of the roller brush and improving the cleaning effect of the roller brush.

[0008] In some embodiments, the protrusion is provided on the top edge of the body and extends along the length direction of the roller brush, and the spray port is provided at the bottom of the protrusion.

[0009] In this way, when water is sprayed out from the spray nozzle, it can be directed toward the surface of a large area of ​​the main body, and the surface of the main body can be cleaned, thereby ensuring the cleaning effect.

[0010] In some embodiments, the body is provided with two separated protrusions, each of the first water storage chambers is connected to at least one water outlet pipe, and the first water storage chamber is inclined downward from the end portion to the middle portion of the body.

[0011] In this way, at least one spray port can be set on each protrusion. At the same time, by tilting downward from the end to the middle of the main body, the water flow can flow downward from the end to the middle of the main body according to gravity, ensuring the water outlet effect in the middle position.

[0012] In some embodiments, a cross-sectional area of ​​the first water storage chamber along the radial direction of the roller brush gradually increases from the end toward the middle of the body.

[0013] In this way, the cross-sectional area is set to gradually increase from the end to the middle of the main body to adapt to the flow pattern of the water. When the water flows from a high position to a low position, it can be stored in a water storage position with a larger water volume, ensuring the safety of water storage.

[0014] In some embodiments, the protrusion is located at an end of the body along the length direction of the roller brush and is arranged in a vertical direction.

[0015] In this way, by providing a protrusion at the end of the roller brush, the flushing effect on the surface of the main body can also be achieved.

[0016] In some embodiments, the mounting frame includes a plurality of the spray ports and a plurality of partitions, the plurality of partitions are separated and arranged in the first water storage chamber, and there is one spray port between every two of the partitions.

[0017] In this way, when water flows out of the water outlet pipe, it flows into the first water storage chamber and flows in the first water storage chamber. The water flow can be blocked by the partition and accumulated between every two partitions, which can ensure that water can continue to flow out of each spray port. At the same time, due to the setting of the partition, the partition and the first water storage chamber have a distance for water flow. The partition blocks the smooth flow of water in the first water storage chamber. The water flow can only flow along the gap between the partition and the cavity wall of the first water storage chamber, which produces a turbulent flow effect, so that the water flow can have a greater flow speed in the water storage chamber to ensure the water outlet speed of the spray port.

[0018] In some embodiments, a second water storage chamber is provided in the mounting frame, and the spray port is communicated with the second water storage chamber and is provided on a side of the mounting frame facing the roller brush.

[0019] In this way, the water flow is directly sprayed out from the spray port toward the roller brush, and the water flow can directly flush the bracket, covering more surfaces of the bracket, thereby ensuring the cleaning effect.

[0020] In some embodiments, the mounting frame is provided with a plurality of the spray ports, which are separated from each other and arranged in a linear array.

[0021] In this way, the spray nozzles arranged along the linear array can be easily formed on the mounting frame and cover more positions of the mounting frame to ensure the cleaning effect.

[0022] In some embodiments, the spray port is trumpet-shaped, and the diameter of the spray port gradually increases toward the roller brush.

[0023] In this way, water flows out of the water storage chamber and can generate a larger cleaning area on the mounting frame, thereby cleaning more garbage on the mounting frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] The present invention will be further described in detail below with reference to the accompanying drawings.

[0040] See also Figures 1 to 10 , a floor scrubber 100 provided in an embodiment of the present invention includes a pressurizing system 10 , a mounting frame 20 and a roller brush 30 .

[0041] Among them, see Figures 1 to 4The pressurizing system 10 includes a pressurizing pump 11 and at least one water outlet pipe 12. The pressurizing pump 11 is used to pressurize the water body, and the water outlet pipe 12 is used to deliver the water body pressurized by the pressurizing pump; the roller brush 30 is used to clean the floor, and the mounting frame 20 is used to clean the garbage on the roller brush 30 and is connected to the water outlet pipe 12. The mounting frame 20 has at least one spray port 21 on the side facing the roller brush 30. The spray port 21 is used to discharge the high-pressure water body delivered through the water outlet pipe 12 to clean the surface of the mounting frame 20.

[0042] The above-mentioned floor scrubber 100 is provided with a pressurizing system 10 to pressurize the water body, and then the high-pressure water body is sprayed out through the spray port 21 of the mounting frame 20, so that the high-pressure water body can clean the surface of the mounting frame 20. Since the high-pressure water body can generate a large impact force on the surface of the mounting frame 20, the garbage adhered to the surface of the mounting frame 20 is washed away, so that the surface of the mounting frame 20 can be kept clean, thereby improving the user experience.

[0043] Specifically, the mounting frame 20 cleans the roller brush 30 in the following manner: the floor scrubber 100 also includes a scraper 50, which is arranged on the top of the main body 22 and is held against the roller brush 30, and is used to scrape away the garbage attached to the roller brush 30. It can be understood that the garbage scraped by the scraper 50 will not only fall to the ground, but also fall to the surface of the main body 22 facing the roller brush 30, so that the garbage accumulates on the surface of the main body 22.

[0044] See also Figure 5 In one embodiment of the present invention, in order to ensure the flushing effect on the surface of the mounting frame 20, the mounting frame 20 includes a main body 22 and a protrusion 23 provided on the main body 22. The protrusion 23 protrudes toward the direction of the roller brush 30. A first water storage chamber 231 is formed in the protrusion 23. The spray port 21 is provided on the protrusion 23 and is connected to the first water storage chamber 231. Therefore, by providing the water storage chamber, the water outlet pipe 12 can pass high-pressure water into the water storage chamber, and the high-pressure water can flow in the water storage chamber, which is convenient for providing multiple spray ports 21 in the protrusion 23. The multiple spray ports 21 can all flow out high-pressure water, thereby covering a larger area to be cleaned on the surface of the mounting frame 20 and improving the cleaning effect of the mounting frame 20.

[0045] Understandably, see Figure 3 The floor scrubber 100 further includes a scraper bar 40 , which is disposed at the bottom of the body 22 , that is, at the end surface of the body 22 facing the ground, for collecting sewage after mopping the ground so that the suction unit can suck it away from the sewage inlet 25 .

[0046] Also, see Figure 3There is a receiving space 24 between the protrusion 23 and the main body 22. The receiving space 24 is used to receive part of the roller brush 30, that is, at least part of the roller brush 30 can extend into the receiving space 24. During the rotation process, the roller brush 30 will also throw out some garbage to the surface of the mounting bracket 20, so the mounting bracket 20 needs to be cleaned after use.

[0047] Specifically, in one embodiment of the present invention, the protrusion 23 is provided at the top edge of the main body 22, the protrusion 23 extends along the length direction of the roller brush 30, and the spray port 21 is provided at the bottom of the protrusion 23, so that when the water is sprayed out of the spray port 21, it can be directed toward a large area of ​​the surface of the main body 22. In order to ensure the cleaning effect, a plurality of separated spray ports 21 with smaller apertures can be provided on the protrusion 23, so that high-pressure water can be sprayed out from the spray ports 21 with smaller apertures; or in order to ensure an efficient flushing effect, one or more long strip-shaped parallel spray ports 21 can be provided along the length direction of the protrusion 23, that is, along the length direction of the roller brush 30, so that water with a larger water flow rate can flow out of the long strip-shaped spray port 21 to ensure the cleaning effect of the roller brush 30. It can be set as needed and is not limited here.

[0048] Specifically, see Figures 4 to 6 In this embodiment, the middle part of the body 22 has a sewage inlet 25, and the water absorption component sucks sewage through the sewage inlet 25. In this embodiment, the body 22 is provided with two separated protrusions 23, and the first water storage chamber 231 is connected to at least one water outlet pipe 12. The first water storage chamber 231 is downwardly inclined from the end to the middle of the body 22, so that at least one spray port 21 can be provided on each protrusion 23. At the same time, by downwardly inclining from the end to the middle of the body 22, the water flow can flow downward from the end to the middle of the body 22 according to gravity, thereby ensuring the water outlet effect at the middle position.

[0049] Specifically, the pressurizing system 10 in this embodiment includes two water outlet pipes 12, and each protrusion 23 is connected to a water outlet pipe 12. In other embodiments, multiple water outlet pipes 12 can be connected in each protrusion 23 according to the size of the cavity of the first water storage chamber 231 and the size of the water outlet pipe 12.

[0050] In addition, in order to ensure the simplicity of the structure and to ensure that there is water at both ends of the protrusion 23, the position where each protrusion 23 is connected to the water outlet pipe 12 in this embodiment is the middle position of the protrusion 23. Since the water will flow from a high position to a low position, in order to ensure the safety of the use of the protrusion 23, the cross-sectional area of ​​the first water storage chamber 231 along the radial direction of the roller brush 30 in this embodiment gradually increases from the end to the middle of the main body 22, that is, the water storage volume of the first water storage chamber 231 near the middle position of the main body 22 is larger, so the cross-sectional area is set to gradually increase from the end to the middle direction of the main body 22 to adapt to the flow pattern of the water flow. When the water flows from a high position to a low position, it can be stored in the water storage position with a larger water storage volume, thereby ensuring the safety of water storage.

[0051] See also Figure 9 In another embodiment of the present invention, the protrusions 23 are located at the ends of the body 22 along the length of the roller brush 30 and are arranged in the vertical direction. The spray port 21 faces the surface of the body 22. Therefore, by providing the protrusions 23 at both ends of the body 22, the surface of the bracket 20 can also be flushed. In this embodiment, the protrusions 23 are provided at both ends of the body 22 along the length of the roller brush 30 to further ensure the cleaning effect.

[0052] It can be understood that the protrusion 23 is provided with a plurality of spray ports 21 separated from each other in the vertical direction, thereby ensuring a flushing effect.

[0053] In addition, in other embodiments, in order to further ensure the cleaning effect, spray ports 21 can be set at the top edge of the main body 22 and both ends of the main body 22, so that the sprayed high-pressure water can cover more area of ​​the mounting frame 20, and the garbage on the roller brush 30 can be cleaned more cleanly to achieve a better cleaning effect.

[0054] In the above two embodiments, whether the protrusion 23 is located at the top of the body 22 or at the end of the body 22, a plurality of separated spray ports 21 can be set on the protrusion 23. In order to ensure the water discharge effect of each spray port 21, please refer to Figure 7 and Figure 8The mounting frame 20 further includes a plurality of partitions 26, which are separated and arranged in the first water storage chamber 231, and a spray port 21 is provided between every two partitions 26. When water flows out of the water outlet pipe 12, it flows into the first water storage chamber 231 and flows in the first water storage chamber 231. The water flow can be blocked by the partition 26 and accumulated between every two partitions 26, that is, it can ensure that water can continue to flow out of each spray port 21; at the same time, due to the arrangement of the partition 26, the partition 26 and the first water storage chamber 231 have a distance for water flow, and the partition 26 blocks the smooth flow of water in the first water storage chamber 231. The water flow can only flow along the gap between the partition 26 and the cavity wall of the first water storage chamber 231, producing a turbulent flow effect, so that the water flow can have a greater flow speed in the water storage chamber to ensure the water outlet speed of the spray port 21.

[0055] See also Figure 10 In another embodiment of the present invention, a second water storage chamber (not shown in the figure) is provided in the mounting frame 20, and the spray port 21 is connected to the second water storage chamber. The spray port 21 is provided on the side of the mounting frame 20 facing the roller brush 30, so that the water outlet pipe 12 flows water to the body 22 of the mounting frame 20, and the second water storage chamber is formed on the body 22. The spray port 21 is connected to the second water storage chamber, so that water is directly sprayed out from the spray port 21, and the water can be directly flushed on the bracket 20, covering more surfaces of the bracket 20, ensuring the cleaning effect.

[0056] Specifically, when the spray port 21 is set on the surface of the mounting frame 20 facing the roller brush 30 in this embodiment, in order to ensure the flushing effect, multiple spray ports 21 need to be set on the mounting frame 20. The multiple spray ports 21 in this embodiment are set apart from each other and arranged along a straight array. By setting the spray ports 21 in an orderly manner, it is convenient to form the spray ports 21 on the mounting frame 20, and the cleaning effect can also be guaranteed. In other embodiments, multiple spray ports 21 can also be set in a disorderly manner, so that the spray ports 21 can clean more positions.

[0057] It can be understood that when the mounting frame 20 is set with the spray port 21 in various ways, multiple water outlet pipes 12 can be set in the pressurized system 10, and the multiple rolling water outlet pipes 12 separate and connect the water storage chamber, so as to ensure the water volume in the water storage chamber, to ensure the water output of the spray port 21, and thus to ensure the cleaning effect.

[0058] Specifically, in order to simplify the structure, the pressurizing system 10 in this embodiment includes two water outlet pipes 12, with one water outlet pipe 12 provided on each side of the sewage inlet 25, so that the water outlet effect can be guaranteed on both sides of the sewage inlet 25 to ensure the cleaning effect.

[0059] In addition, spray ports 21 may be provided at the top, both ends, and one side of the mounting frame 20 facing the roller brush 30 to increase the cleaning area of ​​the bracket 20 and thereby improve the cleaning effect and efficiency.

[0060] In addition, in order to further ensure the speed of water flow and the cleaning effect, the spray port 21 provided in each embodiment of the present invention is trumpet-shaped, and the diameter of the spray port 21 gradually increases toward the roller brush 30, so that when the water flow is sprayed out from the water storage chamber, it can produce a larger cleaning area on the mounting frame 20, and can clean more garbage on the mounting frame 20.

[0061] Understandably, see Figure 1 The floor scrubber 100 in this embodiment further includes a bracket 60 , and the pressurizing system 10 , the mounting frame 20 and the roller brush 30 are all mounted on the bracket 60 .

[0062] The technical means disclosed in the solutions of the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
