Abstract
Description
[0001] This application is a divisional application of Chinese Patent Application No. 202211051286.7, entitled "A Multi-channel Water Spray Cleaning Floor Scrubber", filed on August 31, 2022, the contents of which are incorporated herein by reference. Technical Field
[0002] This invention relates to the field of cleaning equipment technology, and more particularly to a water guide strip, a multi-nozzle water spraying mechanism, and a multi-channel water spraying floor scrubber. Background Technology
[0003] Early floor cleaning tools used by people included brooms, mops, and floor scrubbers, which relied primarily on manual operation. With technological advancements, the demands for floor cleaning tools gradually increased, leading to the emergence of vacuum cleaners. These electric vacuums use negative pressure to suck up debris and dust from the floor. Classified by cleaning methods and the flow path of small and large debris, this type of technology is generally categorized as air-dust circulation technology. However, due to the limitations of its working principle, vacuum cleaners cannot clean some firmly adhered debris and stains. Therefore, a new type of floor scrubber, the "water-dust circulation" model, has emerged. This model uses a motor to drive a cleaning drum, typically made of sponge, to wipe the floor. The floor cleaner also includes a water supply system and a water tank to clean the drum, achieving a thorough cleaning of the floor. To clean the drum, a closed cleaning space connected to the water supply system is usually set up to clean specific sections of the drum, providing clean water for rinsing before the wastewater is pumped away.
[0004] Patent document CN208892449U discloses a floor cleaner and its water tank structure. The water tank structure is formed by a rotating rod on the surface of the cleaning cylinder. When the water supply system releases water from one end of the water tank and pumps out wastewater from the other end, since the water outlet pipe and the water pumping pipe are respectively set perpendicular to the surface of the cleaning cylinder, the water is released and pumped out on the surface of the outer sponge layer. The wastewater is pumped out through the surface of the outer sponge layer and will not remove the garbage on the surface of the water tank, thus preventing blockage of the water supply and pumping system and making the water release and pumping effect better.
[0005] Existing water-dust circulation floor cleaners typically use a closed cleaning space to spray clean water from one side or a single nozzle (or spray clean water from a single nozzle in the middle), and to suck up wastewater from a single nozzle on the other side of the closed cleaning space (or suck up wastewater from two nozzles at both ends). This creates a localized cleaning effect on the roller. However, the clean water travels a relatively long path across the roller surface in the closed cleaning space. As the roller rotates, the cleaning effect of the clean water mixed with wastewater near the wastewater suction port on the later section of the roller surface is far less than the cleaning effect of the clean water sprayed on the front section of the roller, resulting in an unsatisfactory cleaning effect. Summary of the Invention
[0006] The main technical problem solved by this invention is to provide a multi-channel water spray cleaning floor scrubber. When the multi-channel water spray cleaning floor scrubber cleans along the axial direction of the drum, the cleaning effect is poor on the side away from the clean water outlet, and debris tends to accumulate at one end of the drum. This invention aims to improve the cleaning effect of the drum.
[0007] To solve the above-mentioned technical problems, in a first aspect, the present invention provides a water guide strip disposed between the housing of a multi-channel water spray cleaning floor scrubber and the surface of a cleaning roller installed on the housing. A water squeezing strip is also provided between the housing and the surface of the cleaning roller to squeeze the surface of the cleaning roller. A multi-nozzle water spraying mechanism connected to the outlet of a water pump is provided between the water squeezing strip and the water guide strip. The water guide strip includes a first wastewater discharge mechanism to prevent garbage from accumulating at one end of the cleaning roller when cleaning along the axial direction of the cleaning roller.

Each nozzle is equidistant from the first bypass manifold, that is, the first bypass manifold is equidistant from the two adjacent nozzles.
[0017] A second water branch pipe and / or a third water branch pipe are provided between the first water branch pipe and the water inlet pipe. The second water branch pipe is provided with at least two first bypass manifolds connected to the first water branch pipe, and the third water branch pipe is provided with two second bypass manifolds connected to the second water branch pipe.

[0020] In one or more alternative embodiments, the nozzle is a tubular structure protruding from the first water distribution pipe, and the tubular structure is made of a variable-shape material.
[0021] In one or more alternative embodiments, when it is necessary to change the water pressure of the nozzle by means of a water pump during the rinsing process, the angle between the tubular nozzle and the roller can be increased, and at the maximum angle, the water outlet direction of the nozzle is tangent to the surface of the roller.

[0053] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0054] The following will describe the scheme of this application in detail with reference to the accompanying drawings.
[0055] like Figure 1-7 As shown, this invention provides an embodiment of a multi-channel water spray cleaning floor scrubber.
[0056] The multi-channel water spray cleaning floor scrubber includes a housing 1 and a cleaning roller 2 installed on the housing 1. A squeezing strip 3 and a water guiding strip 5 are provided between the surface of the housing 1 and the roller 2. A multi-nozzle spraying mechanism 4 is provided between the squeezing strip 3 and the water guiding strip 5, which is connected to the outlet of a water pump (not shown in the figure) and provides uniform water output from each nozzle. A first wastewater discharge mechanism 6 is provided on the water guiding strip 5. The squeezing strip 3 and the surface of the roller 2 generate appropriate squeezing.
[0057] Specifically, the water guide bar 5 may be provided with a water distribution bar 7, and a water collection trough 9 is formed at the junction of the water distribution bar 7 and the water guide bar 5. A second sewage discharge mechanism 8 is provided in the water collection trough 9.
[0058] The multi-nozzle water spraying mechanism 4 includes a first water distribution pipe 44 with multiple nozzles 42, each nozzle 42 having a water outlet direction tangential to the surface of the roller 2. The first water distribution pipe 44 is connected to one end of a water inlet pipe 41, the other end of which is connected to a water pump. To ensure uniform water output from each nozzle 42, the connection point between the water inlet pipe 41 and the first water distribution pipe 43 is located in the middle of the first water distribution pipe 43.
[0059] As needed, a second water distribution pipe 46 and a third water distribution pipe 48 can be installed between the first water distribution pipe 44 and the water inlet pipe 41. The second water distribution pipe 46 has at least two first bypass manifolds 43 connected to the first water distribution pipe 44, and the third water distribution pipe 48 has two second bypass manifolds 47 connected to the second water distribution pipe 46. The connection point between each first bypass manifold 43 and the first water distribution pipe 44 is located between two nozzles 42, ensuring that each nozzle 42 is equidistant from the first bypass manifold 43. That is, the distance between the first bypass manifold 43 and any two adjacent nozzles 42 is the same.
[0060] The second branch pipe 46 can form a multi-nozzle spraying mechanism with the first branch pipe 44, or the third branch pipe 48, the second branch pipe 46, and the first branch pipe 42 can form a multi-nozzle spraying mechanism together. Two second bypass manifolds 47 are provided between the third branch pipe 48 and the second branch pipe 46, and each second bypass manifold 47 is equidistant from two adjacent first bypass manifolds 43. The number of nozzles 43 is twice the number of first bypass manifolds 43. The number of first bypass manifolds 43 is twice the number of second bypass manifolds 47. The middle part of the third branch pipe 48 is connected to the outlet of a clean water pump (not shown in the attached diagram) via a water inlet pipe 41.
[0061] The cross-sectional area of the water distribution pipe and bypass manifold gradually decreases from the nozzle 42 towards the outlet of the clean water pump, which increases the water velocity at the nozzle 42, thus providing a better washing effect on the roller 2. As needed, the cross-sectional area of the first water distribution pipe 44 is 0.5 times that of the first bypass manifold 43; the cross-sectional area of the second water distribution pipe 46 is 0.5 times that of the second bypass manifold 47. This ensures that the water pressure at each nozzle 42 is basically the same, resulting in a similar rinsing effect on the surface of the roller 2, and thus a better cleaning effect and efficiency.
[0062] To increase the surface area of each nozzle 42 scouring the roller 2, the nozzle 42 can adopt a strip structure, which can reduce the number of nozzles 42, effectively reduce the complexity of the pipeline, and reduce the manufacturing difficulty and production cost of the pipeline.
[0063] As needed, the nozzle 42 protrudes from the first water distribution pipe 44 in a tubular structure. This tubular structure is made of a variable-shape material. When the nozzle 42 is cleaning the surface of the roller 2, the distance between the nozzle 42 and the roller 2 is relatively close, allowing for localized rinsing of the roller 2 surface. During the rinsing process, as the water pressure of the nozzle 42 needs to be changed by the water pump, the angle between the tubular nozzle 42 and the roller 2 can be increased. At the maximum angle, the water outlet direction of the nozzle 42 is tangent to the surface of the roller 2, resulting in a longer rinsing distance. This further separates the debris generated at the beginning of rinsing the surface of the roller 2 from the roller 2, thereby achieving a better cleaning effect.
[0064] like Figure 8 As shown, the first sewage outlet mechanism 6 includes a first collecting pipe with multiple return inlets 62, as needed. The first collecting pipe is connected to a second collecting pipe 63 via at least one first branch pipe 62. The connection point between the first branch pipe 62 and the first collecting pipe is located between two return inlets 61, ensuring that each return inlet 62 is equidistant from the first branch pipe 62. The first sewage outlet mechanism 6 also includes a third branch pipe 65, with two second branch pipes 64 between the third collecting pipe 65 and the second collecting pipe 63, and each second branch pipe 64 is equidistant from its two adjacent first branch pipes 62. The number of return inlets 61 is twice the number of first branch pipes 62. The number of first branch pipes 62 is twice the number of second branch pipes 64. The middle section of the third collecting pipe 65 is connected to the inlet of a sewage pump (not shown in the attached diagram) via a drain pipe 60. The cross-sectional areas of the collecting pipe and branch pipes gradually increase from the return inlets 61 to the outlet of the sewage pump.
[0065] Multi-spray floor scrubbers can evenly spray water tangentially across multiple points on the cleaning drum surface, achieving vertical cleaning and improving cleaning effectiveness. This prevents debris from accumulating at one end of the drum during axial cleaning, ensuring that debris does not negatively impact the cleaning process. Furthermore, the specialized multi-nozzle spray mechanism guarantees consistent water output and pressure from each nozzle, ensuring uniform cleaning results at each cleaning point.
[0066] This invention provides a multi-spray floor scrubber, comprising a housing and a cleaning roller mounted on the housing. A squeezing strip and a guiding strip are provided between the housing and the roller surface. A multi-nozzle spraying mechanism, with each nozzle communicating with a water pump outlet, provides uniform water output. A first wastewater discharge mechanism is provided on the guiding strip. Because the multi-spray floor scrubber can uniformly spray water tangentially at multiple points on the cleaning roller surface during use, it achieves vertical cleaning of the cleaning roller, improving the cleaning effect. It avoids the accumulation of debris at one end of the cleaning roller during axial cleaning, ensuring that debris does not affect the cleaning process. Simultaneously, the specific multi-nozzle spraying mechanism ensures that each nozzle outputs a consistent amount of water and maintains a similar pressure, thus guaranteeing a consistent cleaning effect at each cleaning point.
[0067] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. Furthermore, any changes or modifications made by those skilled in the art based on the ideas of this application, and on the specific implementation methods and application scope of this application, are all within the scope of protection of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
