[0003] Existing wet and dry mopping and sweeping cleaning settings for cleaning tools, such as Chinese Patent Publication No. CN100581433C, during cleaning, form a cleaning cavity on the surface of the cleaning roller, and inject flowing clean water into the cleaning cavity to clean the surface of the cleaning roller that forms part of the cleaning cavity. However, due to the long cleaning cavity, the water flow rate entering the cleaning cavity is limited, and the water flow rate decays rapidly during the cleaning process. As a result, the cleaning effect on the surface of the cleaning roller on the side where clean water enters is better, while the cleaning effect on the sewage side is not ideal. When stubborn garbage adheres to the surface of the cleaning roller, it cannot be separated from the surface of the cleaning roller, thus also affecting the cleaning effect. Summary of the Invention

[0051] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention and are not intended to limit the present invention.

[0052] As Figure 1 - Figure 6 shown, the present invention provides an embodiment of a multi-nozzle cleaning device for a sweeping and mopping integrated cleaning roller.

[0053] The multi-nozzle cleaning device 1 for the sweeping and mopping integrated cleaning roller includes a cleaning roller 2 that rotates during cleaning and a cleaning mechanism for cleaning the surface of the cleaning roller 2. The cleaning mechanism includes a first water pump (not shown in the drawings) that intermittently transports the clear water in a clear water tank (not shown in the drawings) to the surface of the cleaning roller 2 and at least two cleaning nozzles 8 connected to the first water pump. Each cleaning nozzle 8 is respectively provided with a controllable switch (not shown in the drawings) for independently controlling the intermittent non-continuous flushing of the surface of the cleaning roller 2 at intervals.

[0054] Specifically, the multi-nozzle cleaning device 1 of the integrated sweeping and mopping cleaning roller is powered by a power source such as a battery or mains electricity. The cleaning roller 2 is directly or indirectly driven by a roller motor (not shown in the drawings). The cleaning mechanism includes a first water pump (not shown in the drawings) that intermittently transports the clear water in the clear water tank (not shown in the drawings) to the surface of the cleaning roller 2 and at least two cleaning nozzles 8 connected to the first water pump. The cleaning mechanism also includes a water collection mechanism 3 that collects the liquid flowing through the surface of the cleaning roller 2. The water collection mechanism 3 is arranged parallel or non-parallel to the rotating shaft of the cleaning roller 2. When arranged non-parallelly, the water collection mechanism 3 forms an angle with the rotating shaft of the cleaning roller 2, and this angle can be set to 5 - 30 degrees. In this way, when the clear water flushes the surface of the higher side of the cleaning roller 2, the sewage can quickly flow to the lower side by gravity, reducing the contact time between the sewage and the surface of the cleaning roller 2. The controllable switch includes an electromagnetic valve, and each nozzle is controlled by the electromagnetic valve to clean the cleaning roller in a preset manner. The water collection mechanism 3 includes a water collection strip in contact with the surface of the cleaning roller 2. A water collection groove 31 is provided on the water collection strip away from the surface of the cleaning roller 2. By providing the water collection groove 31 away from the surface of the cleaning roller 2, the sewage formed during cleaning can be quickly gathered during the cleaning process, avoiding the retention of the garbage formed on the surface of the cleaning roller 2 due to the long-term contact between the sewage and the surface of the cleaning roller 2 during the cleaning process.

[0055] At least two cleaning nozzles refer to two or more nozzles. For the convenience of description, multiple nozzles are taken as an example. During use, the first water pump intermittently transports the clear water to the multiple nozzles on the cleaning mechanism, and the controllable switch flushes different positions on the surface of the cleaning roller at intervals in a preset manner. For example, multiple nozzles can be controlled to be turned on in sequence, and the spraying duration of adjacent nozzles can be the same or different. After one nozzle finishes spraying, after a preset time interval such as 5 seconds or 10 seconds, another nozzle is made to spray. Since when each nozzle sprays water, the clear water directly acts on the surface of the cleaning roller at a relatively high speed, it can separate the stubborn garbage attached to the surface of the cleaning roller, improving the cleaning effect of the cleaning roller. At the same time, the scattered and spaced flushing of multiple nozzles can clean different positions, making the cleaning of the cleaning roller more uniform, using less water, being able to extend the use time of a single water injection for a longer time, and avoiding the inconvenience caused by frequent water addition during use. Moreover, it can also moisten the surface of the cleaning roller during the cleaning process, ensuring the mopping effect.

[0056] To improve the cleaning effect of the cleaning roller, the clear water outlet direction of the nozzle 8 is tangent to the surface of the cleaning roller 2, that is, the clear water outlet direction is from top to bottom and tangent to the surface of the cleaning roller 2. In this way, the force generated by the clear water of the nozzle 8 can be effectively applied to the stubborn garbage on the surface of the cleaning roller 2, thereby improving the cleaning effect. To improve the cleaning efficiency of the cleaning roller 2 and expand the cleaning area, the nozzle 8 is provided with a strip-shaped water outlet (not shown in the drawings), and this water outlet is parallel to the cleaning roller.

[0057] As required, the integrated sweeping and mopping cleaning tool further includes a sewage tank (not shown in the drawings) communicating with the water collecting tank 31, which can achieve continuous cleaning of garbage for a relatively long time. In order to reduce the retention time of sewage in the water collecting tank 31, a second water pump (not shown in the drawings) is provided between the water collecting tank 31 and the sewage tank (not shown in the drawings), which delays injecting the sewage formed after flowing through the surface of the cleaning roller into the sewage tank after the first water pump intermittently outputs clear water to the surface of the cleaning roller. The second water pump and the first water pump operate asynchronously. Only when the sewage accumulates will the second water pump be started to work and suck the sewage into the sewage tank. On the one hand, this can reduce the useless work of the second water pump. On the other hand, when the sewage is less, there will be air when the second water pump is turned on and the drainage port is not submerged by sewage, resulting in noise.

[0058] During use, the cleaning roller 2 rotates directly or indirectly driven by a motor. The cleaning roller 2 contacts the cleaning surface for cleaning. As the cleaning roller 2 rotates, by appropriately controlling the multiple nozzles 8 on the cleaning mechanism to flush the surface of the cleaning roller 2 intermittently or in a pulsed manner, the multiple nozzles 8 intermittently flush the surface position of the cleaning roller 2, so as to achieve multi-point cleaning with the least amount of water consumption, thereby improving the uniformity of cleaning. In the case of limited clear water, the continuous use time after adding clear water once can be extended, which is convenient for use and has a simple structure.

[0059] As required, in order to quickly gather the sewage, the bottom surface of the water collecting tank 31 is one or two inclined surfaces 30, which can quickly gather the sewage. A water collecting port 32 is provided at the lowest point of the inclined surface. The water collecting port 32 communicates with the sewage tank (not shown in the drawings), so that the sewage can be better collected and discharged. In order to avoid the influence of the garbage washed down on the subsequent cleaning, the spraying direction of each nozzle 8 is offset towards the sewage flow direction. As Figure 5 shown, the direction F in the figure is the sewage flow direction in the water collecting tank 31, that is, the spraying water flow of each nozzle 8 is offset towards the sewage flow direction. It can provide power for the sewage flow, so as to quickly discharge the sewage in the water collecting tank, avoid the sewage contacting for a long time and seeping into the inside of the cleaning roller, and affect the cleaning effect. The first water pump flushes the surface of the cleaning roller 2 through the movable nozzle mechanism.

[0060] As required, the cleaning device further includes a water squeezing strip 4 for squeezing the surface of the cleaning roller. The water squeezing strip 4 is arranged parallel to the cleaning roller 2. The water squeezing strip 4 can squeeze out the liquid adsorbed by the cleaning roller 2 during the cleaning process. The liquid can also take away the dust adsorbed by the cleaning roller 2 together. The squeezed liquid is also sewage in a broad sense, and this liquid will also quickly gather in the water collecting tank 31. The water squeezing strip 4 is arranged behind the cleaning roller 2 where the water collecting mechanism 3 is provided, that is, the water collecting mechanism 3 is arranged in front of the cleaning roller 2 in the direction, and the cleaning roller 2 is arranged behind.

[0061] As shown Figure 7 in the figure, the present invention also provides an embodiment of a cleaning tool.

[0062] The cleaning tool includes a sweeping and mopping integrated cleaning roller multi-nozzle cleaning device 100 and a handle 200 movably connected to the cleaning device. The sweeping and mopping integrated cleaning roller multi-nozzle cleaning device 100, the sweeping and mopping integrated cleaning roller multi-nozzle cleaning device 1, includes a cleaning roller 2 that rotates during cleaning and a cleaning mechanism for cleaning the surface of the cleaning roller 2. The cleaning mechanism includes a first water pump (not shown in the drawing) that intermittently transports the clean water in the clean water tank (not shown in the drawing) to the surface of the cleaning roller 2 and at least two cleaning nozzles 8 connected to the first water pump. Each cleaning nozzle 8 is respectively provided with a controllable switch (not shown in the drawing) for independently controlling the intermittent non-continuous flushing of the surface of the cleaning roller 2.

[0063] Specifically, the sweeping and mopping integrated cleaning roller multi-nozzle cleaning device 1 is powered by a power source such as a battery or mains electricity. The cleaning roller 2 is directly or indirectly driven by a roller motor (not shown in the drawing). The cleaning mechanism includes a first water pump (not shown in the drawing) that intermittently transports the clean water in the clean water tank (not shown in the drawing) to the surface of the cleaning roller 2 and at least two cleaning nozzles 8 connected to the first water pump. The cleaning mechanism further includes a water collecting mechanism 3 for collecting the liquid flowing through the surface of the cleaning roller 2. The water collecting mechanism 3 is arranged parallel or non-parallel to the axis of the cleaning roller 2. When arranged non-parallelly, the water collecting mechanism 3 forms an angle with the axis of the cleaning roller 2, and this angle can be set to 5 - 30 degrees. In this way, when the clean water flushes the surface of the higher side of the cleaning roller 2, the sewage can quickly flow to the lower side by gravity, reducing the contact time between the sewage and the surface of the cleaning roller 2. The controllable switch includes an electromagnetic valve, and each nozzle is controlled by the electromagnetic valve to clean the cleaning roller in a preset manner. The water collecting mechanism 3 includes a water collecting strip in contact with the surface of the cleaning roller 2. The water collecting strip is provided with a water collecting groove 31 away from the surface of the cleaning roller 2. By providing the water collecting groove 31 away from the surface of the cleaning roller 2, the sewage formed during cleaning can be quickly gathered during the cleaning process, avoiding the retention of the garbage formed on the surface of the cleaning roller 2 due to the long-term contact between the sewage and the surface of the cleaning roller 2 during the cleaning process.

[0064] At least two cleaning nozzles refer to two or more nozzles. For the sake of convenience of explanation, multiple nozzles are taken as an example. During use, the first water pump intermittently delivers clean water to multiple nozzles on the cleaning mechanism, and the controllable switch flushes different positions on the surface of the cleaning roller at intervals according to a preset manner. For example, multiple nozzles can be controlled to be turned on in sequence, and the water spraying duration of adjacent nozzles can be the same or different. After a previous nozzle finishes spraying water, after a preset time interval such as 5 seconds or 10 seconds, another nozzle is made to spray water. Since when each nozzle sprays water, the clean water acts directly on the surface of the cleaning roller at a relatively high speed, the stubborn garbage attached to the surface of the cleaning roller can be separated, improving the cleaning effect of the cleaning roller. At the same time, the positions of multiple nozzles are scattered and flushed at intervals, enabling different positions to be cleaned, making the cleaning of the cleaning roller more uniform, using less water, being able to extend the use time of a single water injection for a longer time, and avoiding the inconvenience of frequent water addition during use. Moreover, it can also moisten the surface of the cleaning roller during the cleaning process, ensuring the mopping effect.

[0065] To improve the cleaning effect of the cleaning roller, the water outlet direction of the nozzle 8 is tangent to the surface of the cleaning roller 2, that is, the water outlet direction is from top to bottom and tangent to the surface of the cleaning roller 2. In this way, the force generated by the clean water of the nozzle 8 can be effectively applied to the stubborn garbage on the surface of the cleaning roller 2, thereby improving the cleaning effect. To improve the cleaning efficiency of the cleaning roller 2 and expand the cleaning area, the nozzle 8 is provided with a strip-shaped water outlet (not marked in the attached drawing), and this water outlet is parallel to the cleaning roller.

[0066] According to needs, the integrated sweeping and mopping cleaning tool further includes a sewage tank (not marked in the attached drawing) communicated with the water collecting tank 31, which can achieve continuous cleaning of garbage for a relatively long time. To reduce the retention time of sewage in the water collecting tank 31, a second water pump (not marked in the attached drawing) is provided between the water collecting tank 31 and the sewage tank (not marked in the attached drawing), which delays injecting the sewage formed after flowing through the surface of the cleaning roller into the sewage tank after the first water pump intermittently outputs clean water to the surface of the cleaning roller. This second water pump and the first water pump work asynchronously. Only when the sewage accumulates will the second water pump be started to work and suck the sewage into the sewage tank. In this way, on the one hand, it can reduce the useless work of the second water pump, and on the other hand, when the sewage is less, there will be air when the second water pump is turned on and the drain outlet is not submerged by the sewage, generating noise.

[0067] During use, the cleaning roller 2 rotates directly or indirectly driven by a motor. The cleaning roller 2 comes into contact with the cleaning surface for cleaning. As the cleaning roller 2 rotates, by appropriately controlling multiple nozzles 8 on the cleaning mechanism to flush the surface of the cleaning roller 2 in an intermittent or pulsed manner, multiple nozzles 8 intermittently flush the positions on the surface of the cleaning roller 2, thereby achieving multi-point cleaning with the least amount of water used, improving the cleaning uniformity, extending the continuous use duration of a single addition of clean water under limited clean water conditions, being convenient to use, and having a simple structure.

[0068] As needed, in order to quickly gather sewage, the bottom surface of the water collecting tank 31 is one or two inclined surfaces 30, which can quickly gather sewage. A water collecting port 32 is provided at the lowest point of the inclined surface 30, and the water collecting port 32 is connected to a sewage tank (not shown in the drawings), so that sewage can be better collected and discharged. In order to avoid the influence of the garbage washed down on the subsequent cleaning, the spraying direction of each nozzle 8 is offset towards the sewage flowing direction, as Figure 5 shown. In the figure, the direction F is the flowing direction of sewage in the water collecting tank 31, that is, the spraying water flow of each nozzle 8 is offset towards the sewage flowing direction. It can provide power for the sewage flow, so that the sewage in the water collecting tank can be quickly discharged, avoiding the sewage seeping into the inside of the cleaning drum due to long-term contact and affecting the cleaning effect. The first water pump flushes the surface of the cleaning drum 2 with clean water through the movable nozzle mechanism.

[0069] As needed, the cleaning device further includes a water squeezing strip 4 for squeezing the surface of the cleaning drum. The water squeezing strip 4 is arranged parallel to the cleaning drum 2. The water squeezing strip 4 can squeeze out the liquid adsorbed by the cleaning drum 2 during the cleaning process. The liquid can also take away the dust adsorbed by the cleaning drum 2 together. The extruded liquid is also sewage in a broad sense, and this liquid will also quickly gather in the water collecting tank 31. The water squeezing strip 4 is arranged behind the cleaning drum 2 where the water collecting mechanism 3 is located, that is, the water collecting mechanism 3 is arranged in front of the cleaning drum 2 in the direction, and the cleaning drum 2 is arranged behind.

[0070] The present invention also provides an embodiment of a cleaning tool control method. The cleaning tool control method includes two or more nozzles spraying water alternately, and there is a spraying interval between different nozzles. The spraying direction of the nozzles directly flushes different positions on the surface of the cleaning drum from top to bottom.

[0071] Specifically, the structural components used in the cleaning tool control method adopt the cleaning tool in the above embodiment. When the nozzles flush the surface of the cleaning drum, the nozzles move in the same direction as the sewage flow, which can provide power for the sewage flow, so that the sewage in the water collecting tank can be quickly discharged, avoiding the sewage seeping into the inside of the cleaning drum due to long-term contact and affecting the cleaning effect.

[0072] As needed, after each time the nozzles flush the surface of the cleaning drum 2, the sewage formed by the cleaning is injected into the sewage tank after a delay. Specifically, the second water pump and the first water pump work asynchronously. Only when the sewage accumulates will the second water pump be started to work to suck the sewage into the sewage tank. On the one hand, this can reduce the useless work of the second water pump. On the other hand, when the sewage is less, there will be air when the second water pump is turned on and the drain port is not submerged by sewage, generating noise.

[0073] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
