Description

[0001] This application is a divisional application of Chinese patent application number 202210014169.7, and invention name is "Mop-sweep cleaning roller multi-nozzle cleaning device, cleaning tool and control method", the content of which is incorporated herein by reference. Technical Field

[0002] The present invention relates to cleaning equipment, and in particular to a multi-nozzle cleaning device for a mopping and sweeping integrated cleaning roller, a cleaning tool and a control method. Background Art

[0003] Existing cleaning tools with wet and dry mopping and sweeping configurations, such as those in Chinese Patent Publication No. CN100581433C, form a cleaning cavity on the surface of a cleaning drum during cleaning. Fresh water is then introduced into the cavity to clean the surface of the drum, which forms part of the cleaning cavity. However, due to the length of the cleaning cavity, the water flow rate entering the cavity is limited, and the water flow rate rapidly decays during the cleaning process. This results in better cleaning of the drum surface on the side where fresh water enters, while less effective cleaning on the side where waste water enters. If stubborn debris adheres to the drum surface, it cannot be separated from the drum surface, thus affecting the cleaning effect. Summary of the Invention

[0004] The main technical problem solved by the present invention is to provide a multi-nozzle cleaning device for a cleaning roller with a sweeping function, a cleaning tool and a control method, wherein the multi-nozzle cleaning device for the cleaning roller can evenly clean the garbage on the surface of the cleaning roller, and can also effectively clean the stubborn garbage attached to it.

[0051] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

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

[0053] The multi-nozzle cleaning device 1 for a mopping and sweeping 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 drawing) that intermittently transports clean water from a 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 provided with a controllable switch (not shown in the drawing) that independently controls each cleaning nozzle to discontinuously flush the surface of the cleaning roller 2 at intervals.

[0054] Specifically, the integrated mopping and sweeping cleaning drum multi-nozzle cleaning device 1 is powered by a power source, such as a battery or mains electricity. The cleaning drum 2 is directly or indirectly driven by a drum motor (not shown in the drawings). The cleaning mechanism includes a first water pump (not shown in the drawings) that intermittently delivers clean water from a clean water tank (not shown in the drawings) to the surface of the cleaning drum 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 liquid flowing through the surface of the cleaning drum 2. The water collection mechanism 3 is arranged parallel or non-parallel to the rotating axis of the cleaning drum 2. When arranged non-parallel, the water collection mechanism 3 forms an angle with the rotating axis of the cleaning drum 2, which can be set to 5-30 degrees. In this way, when clean water flushes the higher side of the cleaning drum 2, the dirty water can quickly flow to the lower side due to gravity, reducing the contact time between the dirty water and the surface of the cleaning drum 2. The controllable switch includes a solenoid valve, which controls each nozzle to clean the cleaning drum according to a preset method. The water collection mechanism 3 includes a water collection bar in contact with the surface of the cleaning roller 2, and the water collection bar is provided with a water collection groove 31 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 by cleaning can be quickly collected during the cleaning process, avoiding the sewage from being in contact with the surface of the cleaning roller 2 for a long time during the cleaning process, and the retention of garbage formed on the surface of the cleaning roller 2.

[0055] At least two cleaning nozzles refer to two or more nozzles. For ease of explanation, multiple nozzles are used as an example. During use, the first water pump intermittently delivers clean 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 open in sequence, and the spraying time of adjacent nozzles can be the same or different. After the previous nozzle finishes spraying water, another nozzle sprays water after a preset time interval, such as 5 seconds or 10 seconds. Since each nozzle directly acts on the surface of the cleaning roller at a high speed when spraying water, it can separate stubborn garbage attached to the surface of the cleaning roller and improve the cleaning effect of the cleaning roller. At the same time, the multiple nozzles are dispersed and flushed at intervals, which can clean different positions, making the cleaning roller clean more evenly, using less water, and extending the use time of a single water injection, avoiding the inconvenience of frequently adding water hoses during use. It can also moisten the surface of the cleaning roller during the cleaning process to ensure the mopping effect.

[0056] To improve the cleaning effect of the cleaning drum, the clean water outlet direction of the nozzle 8 is tangential to the surface of the cleaning drum 2, that is, the clean water outlet direction is from top to bottom and tangential to the surface of the cleaning drum 2. This can effectively apply the clean water from the nozzle 8 to the stubborn garbage on the surface of the cleaning drum 2, thereby improving the cleaning effect. To improve the cleaning efficiency of the cleaning drum 2 and expand the cleaning area, the nozzle 8 is provided with a strip-shaped water outlet (not shown in the drawings) that is parallel to the cleaning drum.

[0057] As needed, the mopping and sweeping cleaning tool also includes a sewage tank (not shown in the drawings) connected to the sump 31, allowing for continuous garbage cleaning for an extended period of time. To reduce the amount of time sewage remains in the sump 31, a second water pump (not shown in the drawings) is provided between the sump 31 and the sewage tank (not shown in the drawings). After the first water pump intermittently outputs clean water to the surface of the cleaning drum, it delays the flow of sewage formed after the cleaning drum has passed through the surface and injects it into the sewage tank. The second water pump operates asynchronously with the first water pump and is only activated when sewage is collected, drawing the sewage into the sewage tank. This reduces wasted work by the second water pump and, when sewage is low, prevents air from accumulating at the drain outlet after the second water pump is turned on, generating noise.

[0058] During use, the cleaning roller 2 rotates under the direct or indirect drive of the motor, and the cleaning roller 2 contacts the cleaning surface for cleaning. As the cleaning roller 2 rotates, the multiple nozzles 8 on the cleaning mechanism are appropriately controlled to intermittently or pulse the surface of the cleaning roller 2 with clean water, so that the multiple nozzles 8 intermittently flush the surface of the cleaning roller 2, thereby achieving multi-point cleaning with a minimum amount of water, thereby improving the uniformity of cleaning. In the case of limited clean water, the continuous use time of adding clean water is extended, it is convenient to use, and has a simple structure.

[0059] According to the needs, in order to quickly collect the sewage, the bottom surface of the water collection tank 31 is one or two inclined surfaces 30, which can quickly collect the sewage. A water collection port 32 is provided at the lowest point of the inclined surface. The water collection port 32 is connected to the sewage tank (not shown in the figure), so that the sewage can be better collected and discharged. In order to avoid the influence of the washed garbage on the subsequent cleaning, the water spraying direction of each nozzle 8 is offset to the direction of sewage flow, such as Figure 5 As shown, direction F in the figure represents the flow direction of sewage in the sump 31, i.e., the water jets from each nozzle 8 are offset in the direction of sewage flow. This provides power for the sewage flow, thereby quickly draining the sewage from the sump, preventing prolonged contact with the sewage and its infiltration into the cleaning drum, which could affect cleaning performance. The first water pump flushes the surface of the cleaning drum 2 with clean water through the movable nozzle mechanism.

[0060] As needed, the cleaning device further includes a water squeezing bar 4 for squeezing the surface of the cleaning roller. The water squeezing bar 4 is arranged parallel to the cleaning roller 2. The water squeezing bar 4 can squeeze out the liquid adsorbed by the cleaning roller 2 during the cleaning process. The liquid can also carry away the dust adsorbed by the cleaning roller 2 from the cleaning roller 2. The squeezed liquid is also sewage in a broad sense, and the liquid will also be quickly concentrated in the water collection tank 31. The water squeezing bar 4 is arranged behind the water collection mechanism 3 of the cleaning roller 2, that is, the water collection mechanism 3 is arranged in front of the cleaning roller 2, and the cleaning roller 2 is arranged at the rear.

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

[0062] The cleaning tool includes a multi-nozzle cleaning device 100 for a cleaning roller that is mopped and swept, and a handle 200 movably connected to the cleaning device. The multi-nozzle cleaning device 100 for a cleaning roller that is mopped and swept, and the multi-nozzle cleaning device 1 for a cleaning roller that is mopped and swept include 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 clean water from a 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 provided with a controllable switch (not shown in the drawing) that independently controls each cleaning nozzle to discontinuously flush the surface of the cleaning roller 2 at intervals.

[0063] Specifically, the integrated mopping and sweeping cleaning drum multi-nozzle cleaning device 1 is powered by a power source, such as a battery or mains electricity. The cleaning drum 2 is directly or indirectly driven by a drum motor (not shown in the drawings). The cleaning mechanism includes a first water pump (not shown in the drawings) that intermittently delivers clean water from a clean water tank (not shown in the drawings) to the surface of the cleaning drum 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 liquid flowing through the surface of the cleaning drum 2. The water collection mechanism 3 is arranged parallel or non-parallel to the rotating axis of the cleaning drum 2. When arranged non-parallel, the water collection mechanism 3 forms an angle with the rotating axis of the cleaning drum 2, which can be set to 5-30 degrees. In this way, when clean water flushes the higher side of the cleaning drum 2, the dirty water can quickly flow to the lower side due to gravity, reducing the contact time between the dirty water and the surface of the cleaning drum 2. The controllable switch includes a solenoid valve, which controls each nozzle to clean the cleaning drum according to a preset method. The water collection mechanism 3 includes a water collection bar in contact with the surface of the cleaning roller 2, and the water collection bar is provided with a water collection groove 31 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 by cleaning can be quickly collected during the cleaning process, avoiding the sewage from being in contact with the surface of the cleaning roller 2 for a long time during the cleaning process, and the retention of garbage formed on the surface of the cleaning roller 2.

[0064] At least two cleaning nozzles refer to two or more nozzles. For ease of explanation, multiple nozzles are used as an example. During use, the first water pump intermittently delivers clean 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 open in sequence, and the spraying time of adjacent nozzles can be the same or different. After the previous nozzle finishes spraying water, another nozzle sprays water after a preset time interval, such as 5 seconds or 10 seconds. Since each nozzle directly acts on the surface of the cleaning roller at a high speed when spraying water, it can separate stubborn garbage attached to the surface of the cleaning roller and improve the cleaning effect of the cleaning roller. At the same time, the multiple nozzles are dispersed and flushed at intervals, which can clean different positions, making the cleaning roller clean more evenly, using less water, and extending the use time of a single water injection, avoiding the inconvenience of frequently adding water hoses during use. It can also moisten the surface of the cleaning roller during the cleaning process to ensure the mopping effect.

[0065] To improve the cleaning effect of the cleaning drum, the clean water outlet direction of the nozzle 8 is tangential to the surface of the cleaning drum 2, that is, the clean water outlet direction is from top to bottom and tangential to the surface of the cleaning drum 2. This can effectively apply the clean water from the nozzle 8 to the stubborn garbage on the surface of the cleaning drum 2, thereby improving the cleaning effect. To improve the cleaning efficiency of the cleaning drum 2 and expand the cleaning area, the nozzle 8 is provided with a strip-shaped water outlet (not shown in the drawings) that is parallel to the cleaning drum.

[0066] As needed, the mopping and sweeping cleaning tool also includes a sewage tank (not shown in the drawings) connected to the sump 31, allowing for continuous garbage cleaning for an extended period of time. To reduce the amount of time sewage remains in the sump 31, a second water pump (not shown in the drawings) is provided between the sump 31 and the sewage tank (not shown in the drawings). After the first water pump intermittently outputs clean water to the surface of the cleaning drum, it delays the flow of sewage formed after the cleaning drum has passed through the surface and injects it into the sewage tank. The second water pump operates asynchronously with the first water pump and is only activated when sewage is collected, drawing the sewage into the sewage tank. This reduces wasted work by the second water pump and, when sewage is low, prevents air from accumulating at the drain outlet after the second water pump is turned on, generating noise.

[0067] During use, the cleaning roller 2 rotates under the direct or indirect drive of the motor, and the cleaning roller 2 contacts the cleaning surface for cleaning. As the cleaning roller 2 rotates, the multiple nozzles 8 on the cleaning mechanism are appropriately controlled to intermittently or pulse the surface of the cleaning roller 2 with clean water, so that the multiple nozzles 8 intermittently flush the surface of the cleaning roller 2, thereby achieving multi-point cleaning with a minimum amount of water, thereby improving the uniformity of cleaning. In the case of limited clean water, the continuous use time of adding clean water is extended, it is convenient to use, and has a simple structure.

[0068] According to the needs, in order to quickly collect the sewage, the bottom surface of the water collection tank 31 is one or two inclined surfaces 30, which can quickly collect the sewage. A water collection port 32 is provided at the lowest point of the inclined surface. The water collection port 32 is connected to the sewage tank (not shown in the figure), so that the sewage can be better collected and discharged. In order to avoid the influence of the washed garbage on the subsequent cleaning, the water spraying direction of each nozzle 8 is offset to the direction of sewage flow, such as Figure 5 As shown, direction F in the figure represents the flow direction of sewage in the sump 31, i.e., the water jets from each nozzle 8 are offset in the direction of sewage flow. This provides power for the sewage flow, thereby quickly draining the sewage from the sump, preventing prolonged contact with the sewage and its infiltration into the cleaning drum, which could affect cleaning performance. 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 bar 4 for squeezing the surface of the cleaning roller. The water squeezing bar 4 is arranged parallel to the cleaning roller 2. The water squeezing bar 4 can squeeze out the liquid adsorbed by the cleaning roller 2 during the cleaning process. The liquid can also carry away the dust adsorbed by the cleaning roller 2 from the cleaning roller 2. The squeezed liquid is also sewage in a broad sense, and the liquid will also be quickly concentrated in the water collection tank 31. The water squeezing bar 4 is arranged behind the water collection mechanism 3 of the cleaning roller 2, that is, the water collection mechanism 3 is arranged in front of the cleaning roller 2, and the cleaning roller 2 is arranged at the rear.

[0070] The present invention also provides an embodiment of a cleaning tool control method, which includes two or more nozzles spraying water alternately, with spraying intervals between different nozzles, and the spraying direction of the nozzles directly flushing different positions on the surface of the cleaning roller from top to bottom.

[0071] Specifically, the cleaning tool control method utilizes the structural components of the cleaning tool described in the aforementioned embodiment. When the nozzle flushes the surface of the cleaning drum, it moves in the same direction as the sewage flow, providing momentum for the sewage flow and thereby rapidly draining the sewage from the sump, preventing prolonged contact with the sewage and its infiltration into the cleaning drum, which could affect the cleaning effect.

[0072] As needed, after each flushing of the cleaning drum 2 by the nozzle, the wastewater generated by cleaning is then injected into the wastewater tank with a delay. Specifically, the second water pump operates asynchronously with the first water pump. Only when wastewater has accumulated does the second water pump activate, drawing wastewater into the wastewater tank. This reduces wasted work by the second water pump and, when wastewater is low, prevents the presence of air and noise generated by the second water pump when the outlet is not submerged in wastewater.

[0073] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein, and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
