Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a multi-power dust collection system and a working method thereof. Background Art

[0002] At present, in the field of cleaning equipment, dust collectors are widely used as auxiliary dust collection equipment for cleaning devices such as sweepers. Most common dust collectors adopt a single-power dust collection mode, that is, they mainly rely on the fan inside the dust collector to generate suction to suck out the dust in the dust box of the sweeper and collect it in the dust collector. In this traditional single-power dust collection process, the dust collection wind flow field is mostly in a laminar state. Due to the characteristics of laminar flow, its wind direction is relatively single and stable. When collecting dust from the dust box of the sweeper, the garbage located in the corners of the dust box is often difficult to be effectively sucked out.

[0003] And because laminar flow cannot form enough disturbance and entrainment force on the corners, some garbage remains in the corners of the dust box, affecting the overall dust collection effect and cleaning efficiency. With the continuous improvement of the cleaning performance requirements of cleaning equipment, this single-power dust collection and laminar flow-based dust collection method has gradually exposed its limitations and is difficult to meet the user's needs for efficient and thorough cleaning. Therefore, an innovative dust collection technology is needed to solve this problem, thereby increasing the dust collection rate and improving the cleaning effect. Summary of the invention

[0010] Further preferably, in the first air duct, a first arc-shaped guide surface is provided on one side of the first arc-shaped segment close to the air inlet end. After the airflow enters from the air inlet end, it is guided by the first arc-shaped guide surface to flow toward the air outlet end along the extension direction of the bottom plate.

[0011] Preferably, the setting width of the second fan air inlet is adapted to the setting width of the air inlet end of the dust storage box, and the setting width of the filter plate is greater than the setting width of the second fan air inlet.

[0012] Preferably, the dust storage box also includes a first stopper and a second stopper, the first stopper is disposed at the air inlet end, the first stopper is movably connected to the first arc segment, the second stopper is disposed at the air outlet end, and the second stopper is movably connected to the first straight segment; wherein the first stopper and the second stopper give way to allow airflow to enter the dust storage box from the air inlet end to enter the dust collecting assembly through the air outlet end.

[0013] Preferably, a working method of a multi-power dust collection system is provided, wherein the multi-power dust collection system includes a dust suction module and a dust collection module, the dust collection module controls the start and stop of the first fan, and the dust suction module controls the start and stop of the roller brush and the second fan, and the working method includes: step S10: controlling the first fan to run continuously to generate suction for dust collection; step S20: while the first fan is running, controlling the roller brush and / or the second fan to run and rotate with first preset parameters; step S30: determining whether the remaining amount of debris is zero; step S40: if it is determined to be yes, controlling the first fan, the roller brush and the second fan to stop running; if it is determined to be no, returning to step S20.

[0014] Further preferably, in step S20, it also includes: the roller brush and / or the second fan operate at an initial rotational speed c; the roller brush and / or the second fan are controlled to operate for n cycles, a single operation cycle time is set to t1, and a cycle interval time is set to t2; as the operation cycle progresses, based on the initial rotational speed c, the rotational speed of the first fan and / or the roller brush in a subsequent operation cycle increases by a change x compared to the rotational speed of the previous operation cycle.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] 1. During the dust collection process, the first fan generates an airflow with a circulation trend from right to left, the roller brush rotates to generate an airflow with a circulation trend from lower right to upper left, and the second fan runs to generate an airflow with a circulation trend from bottom to top. These three airflows with different wind directions collide in the dust storage box to form turbulence, which can effectively bring the debris in the corners of the dust storage box into the dust collection component, solving the problem that laminar flow is difficult to suck out corner garbage in common single-power dust collection, thereby improving the overall dust collection efficiency.

[0017] 2. During the dust collection process, since the roller brush is in a rotating state, the airflow generated by the first fan and the airflow generated by the rotation of the roller brush itself not only helps to form turbulence in the dust storage box to take away the debris, but also can absorb the debris remaining on the roller brush itself during the cleaning process, thereby realizing a certain degree of self-cleaning function of the roller brush and reducing the occurrence of the situation where the roller brush is affected by the accumulation of residual debris and the cleaning effect is affected.

[0018] 3. If only the first fan and the second fan are running at the same time, the airflow generated by the second fan will affect the suction generated by the first fan to a certain extent, and reduce the overall dust collection suction effect to a certain extent, because the airflow directions they generate are inconsistent. After adding the airflow of a specific wind direction generated by the rotation of the roller brush, this application document changes the overall situation of the airflow. Since the airflow generated by the first fan and the airflow generated by the rolling of the roller brush are located in the dust storage box with the same flow direction, the influence of the different flow directions of the airflow generated by the second fan on the dust collection suction is weakened, thereby ensuring that the turbulence generated by the collision of the three airflows can flow toward the dust collection component, improving the overall suction and ensuring the smooth progress of the dust collection work.

DETAILED DESCRIPTION

[0030] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0032] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0033] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0034] In a preferred embodiment, see Figures 1 to 9The present application document provides a multi-power dust collection system 11, including: a dust collection component 10 and a dust collection component 20, the dust collection component 10 is connected to the dust collection component 20, the dust collection component 20 is used to absorb the debris 4 in the dust storage box 15 of the dust collection component 10, the dust collection component 20 is provided with a first fan 21, the dust collection component 10 is provided with a roller brush 12 and a second fan 11, the dust collection component 10 is provided with a roller brush 12; the first fan 21 is operated to generate a right-to-left flow in the dust storage box 15 The roller brush 12 rotates to generate an airflow from the lower right to the upper left in the dust box 15, and the second fan 11 runs to generate an airflow from bottom to top in the dust box 15. The three airflows of different directions collide in the dust box 15 to make the airflow in the dust box 15 turbulent. The airflow velocity generated by the rotation of the roller brush 12 is greater than the airflow velocity generated by the second fan 11, and the airflow in the turbulent state finally carries the debris 4 to the dust collecting component 20.

[0035] The dust collecting assembly 10 is used to collect external debris 4, garbage and other items, and temporarily store them in the dust storage box 15 of the dust collecting assembly 10. This process is the dust collecting process. When the debris 4 in the dust storage box 15 accumulates to a certain extent, the dust collecting assembly 20 is needed to empty the garbage in the dust storage box 15 so as to facilitate the next use of the dust collecting assembly 10. Figure 4 If only relying on the suction force generated in a single direction by the first fan 21 , it is difficult to suck the debris 4 and other items in the corners of the dust storage box 15 into the dust collecting assembly 20 .

[0036] Therefore, this application document passes through the dust collection process, see Figure 2 The direction of movement of the airflow is indicated by a solid arrow, that is, during the operation of the first fan 21, the roller brush 12 rotates synchronously, and the airflow generated by the first fan 21 flows from right to left in the cavity of the dust box 15, and the airflow generated by the rotation of the roller brush 12 flows from the lower right to the upper left in the cavity of the dust box 15. At the same time, a second fan 11 is also provided in the dust collection component 10, and the second fan 11 is synchronously operated to generate an airflow flowing from bottom to top in the cavity of the dust box 15. The flow directions of the above three airflows are all explanations of the movement trends of the airflow. Due to the different movement trends of the three airflows, the three airflows collide in the dust box 15 to generate turbulence to disturb the flow state of the airflow flowing to the dust collection component 20. That is, the wind field flow channel in the dust box 15 is changed from the original single-direction laminar wind direction to the turbulent wind direction surrounding multiple directions, that is Figure 3 and Figure 5 As shown, the turbulent wind directions in multiple directions can effectively bring the debris 4 located at the corners of the dust storage box 15 into the dust collecting assembly 20.

[0037] At the same time, during the pre-dust collection process of the dust collection component 10, since the roller brush 12 is a cylindrical structure and has structures such as a brush and a scraper, when the roller brush 12 rolls to clean the garbage debris 4, the brush on the roller brush 12 is also very easy to stick to the garbage debris 4, and the debris 4 stuck on the roller brush 12 cannot be effectively brought into the dust storage box 15. Therefore, during the dust collection process, the rotation of the roller brush 12 cooperates with the suction force generated by the first fan 21 to further effectively clean the debris 4 contaminated around the roller brush 12. The scraper is a V-shaped protrusion relative to the cylindrical surface of the roller brush 12. On the one hand, during the dust collection process, the rotation of the roller brush 12 collects the debris 4 through the scraper. When the dust collection process is performed, the airflow generated by the rotation of the roller brush 12 is generated by the rotation of the scraper set on the roller brush 12.

[0038] In some dust collection processes, either the second fan 11 or the roller brush 12 can be operated alone to save some energy consumption while ensuring the air flow disturbance effect.

[0039] Preferably, the second fan 11 is operated synchronously with the roller brush 12. If in some related technologies, the second fan 11 is operated alone, the suction generated by the first fan 21 is mutually exclusive. Although it has a disturbing effect on the airflow in the dust box 15, it will reduce a part of the suction generated by the first fan 21 on the dust box 15. Therefore, it is preferred that the second fan 11 is operated synchronously with the roller brush 12, and the rotation speed of the roller brush 12 during the dust collection process may be greater than the rotation speed of the roller brush 12 during the dust suction process, and then the airflow velocity generated by the rotation of the roller brush 12 is greater than the airflow velocity generated by the second fan 11, and the airflow direction provided by the rotation of the roller brush 12 is consistent with the airflow direction of the suction generated by the first fan 21, which can make up for the suction reduced by the operation of the second fan 11 to a certain extent, and then the airflow in the turbulent state finally carries the debris 4 to the dust collecting component 20.

[0040] For further preference, see Figure 2 The multi-power dust collection system 1 also includes a first air duct and a second air duct. The inlet of the first air duct is located in the cavity where the roller brush 12 is located. The outlet of the first air duct is the outlet of the first fan 21. The inlet of the second air duct is located in the cavity where the roller brush 12 is located. The outlet of the second air duct is the outlet of the second fan 11. The first air duct is formed by the cavity where the roller brush 12 is located, the space in the bottom plate 151 area of ​​the dust storage box 15, and the pipeline where the first fan 21 is located, and the first air duct is connected in sequence. The first air duct is a linear structure. The second air duct is formed by the cavity where the roller brush 12 is located, the top space surrounded by the side plate 152 of the dust storage box 15, the through hole provided on the filter plate 16, and the pipeline where the second fan 11 is located, and the second air duct is a U-shaped structure.

[0041] Therefore, in the first air duct, the direction of the airflow is to enter through the open mouth opened at the position of the roller brush 12, and through the influence of the suction of the first fan 21, flow to the pipeline of the first fan 21 in the dust collecting assembly 20 through the dust storage box 15, and be discharged from the air outlet of the first fan 21. In the second air duct, the direction of the airflow is to enter through the open mouth opened at the position of the roller brush 12, and through the influence of the suction of the second fan 11, the airflow moves upward in the dust storage box 15, and is discharged through the filter plate 16. As the airflow tends to flow upward, the airflow flows in the direction of the second fan 11, that is, along the upper side, flows to the pipeline of the second fan 11, and is discharged along the air outlet.

[0042] Further preferably, the structures of the first air duct and the second air duct are described, and the internal structure of the dust storage box 15 corresponds to the partial structure of the first air duct and the second air duct. Therefore, the dust storage box 15 includes a bottom plate 151, see Figures 6 to 9 , and the dust storage box 15 is provided with an air inlet end 153 and an air outlet end 154, the air inlet end 153 is close to the roller brush 12 side, and the air outlet end 154 is close to the dust collecting component 20 side, the bottom plate 151 includes a first straight section 1511 and a first arc section 1512 which are arranged in an integrated transition, the first straight section 1511 is in contact with the bottom plane of the dust collecting component 10 and extends to the air outlet end 154, and the first arc section 1512 extends to the air inlet end 153.

[0043] For further preference, see Figure 7 The dust storage box 15 also includes a side panel 152, which is connected to the bottom panel 151. The side panel 152 includes a second straight section 1521 and a second arc section 1522 which are integrated into a transition arrangement. The second straight section 1521 is connected to the first arc section 1512, and the second arc section 1522 is connected to the first straight section 1511 to allow airflow in the first air duct to circulate.

[0044] Preferably, the dust storage box 15 also includes a first stopper 13 and a second stopper 14, the first stopper 13 is placed at the air inlet end 153, the first stopper 13 is movably connected to the first arc segment 1512, the second stopper 14 is placed at the air outlet end 154, and the second stopper 14 is movably connected to the first straight segment 1511; wherein the first stopper 13 and the second stopper 14 give way to allow the airflow to enter the dust storage box 15 from the air inlet end 153 to enter the dust collecting assembly 20 through the air outlet end 154.

[0045] The opening of the air inlet end 153 of the dust storage box 15 is larger than the opening of the air outlet end 154, and the opening of the air inlet end 153 to the opening of the air outlet end 154 is gradually reduced by the side plate 152, so as to ensure the flow rate of the gas discharged from the air outlet end 154 and the dust collection effect. At the same time, the second straight section 1521 of the side plate 152 is connected to one side of the air inlet end 153 to reduce the accumulation of debris 4 entering from the air inlet end 153 in the dust storage box 15, and the second arc section 1522 can effectively improve the drainage effect on the airflow in the first air duct and reduce the backflow of the airflow in the dust storage box 15.

[0046] Also, see Figure 8 , by connecting the first arc segment 1512 in the bottom plate 151 and the second straight segment 1521 in the side plate 152, wherein the first arc segment 1512 is bent and raised relative to the plane where the first straight segment 1511 is located, and thus the volume enclosed by the connection between the first arc segment 1512 and the second straight segment 1521 is smaller than the volume enclosed by the second arc segment 1522 and the first straight segment 1511, sacrificing a part of the dust storage space on the side of the air inlet end 153, but the accumulation amount of debris 4 on the side of the air inlet end 153 can be further reduced, and at the same time, the arc-shaped raised first arc segment 1512 can facilitate the guidance of the airflow flowing in from the cavity opening of the roller brush 12, thereby increasing the airflow velocity and thus improving the dust collection effect.

[0047] Preferably, in the first air duct, see Figure 8 A first arc-shaped guide surface 155 is provided on one side of the first arc-shaped segment 1512 close to the air inlet end 153. After the airflow enters from the air inlet end 153, it is guided by the first arc-shaped guide surface 155 to flow toward the air outlet end 154 along the extension direction of the bottom plate 151, so as to improve the circulation effect of the airflow in the first air duct; similarly, see Fig. 9 At the air outlet end 154 , the second arc section 1522 of the side plate 152 is provided with a second arc guide surface 156 , which has a certain convergence effect on the airflow, facilitating the airflow to flow to the outlet where the second stopper 14 is located.

[0048] Furthermore, Figure 7 The figure shows the assembly setting relationship between the filter plate 16 and the dust box 15. The setting width of the air inlet of the second fan 11 is compatible with the setting width of the air inlet end 153 of the dust box 15, and the setting width of the filter plate 16 is greater than the setting width of the air inlet of the second fan 11. Therefore, on the premise of ensuring that the filter plate 16 has a certain setting area, that is, one side of the long side of the filter plate 16 is longer than the opening length of the air inlet end 153 of the dust box 15, and one side of the short side of the filter plate 16 is as close to the side plate 152 of the dust box 15 as possible to improve the filtering and air outlet effects, ensure that the dust box 15 can be in a negative pressure state during the dust collection process, and improve the dust collection effect.

[0049] Preferably, a working method of a multi-power dust collection system 1 is provided, wherein the multi-power dust collection system 1 includes a dust suction module and a dust collection module, the dust collection module controls the start and stop of the first fan 21, and the dust suction module controls the start and stop of the roller brush 12 and the second fan 11, and the working method includes: step S10: controlling the first fan 21 to run continuously to generate suction for dust collection; step S20: while the first fan 21 is running, controlling the roller brush 12 and / or the second fan 11 to run and rotate with a first preset parameter; step S30: determining whether the remaining amount of debris 4 is zero; step S40: if it is determined to be yes, controlling the first fan 21, the roller brush 12 and the second fan 11 to stop running; if it is determined to be no, returning to step S20.

[0050] Among them, a sensor module is provided at the position of the dust storage box 15, and the sensor module is used to sense the remaining amount of debris 4 in the dust storage box 15, and the diameter of the debris 4 sensed by the detection can be set to be larger than the set diameter to avoid some dust with too small diameter from misdetecting the sensor module. And preferably, a sensor module is provided at the position of the roller brush 12, and when the roller brush 12 and the first fan 21 are running synchronously, the sensor module can synchronously detect the remaining amount of debris 4 on the roller brush 12, and if the remaining amount of debris 4 in any of the above (inside the dust storage box 15, on the roller brush 12) does not reach zero, it still returns to step S20 to continue the dust collection operation.

[0051] Further preferably, in step S20, it also includes: the roller brush 12 and / or the second fan 11 operate at an initial rotational speed c; the roller brush 12 and / or the second fan 11 are controlled to operate for n cycles, a single operation cycle time is set to t1, and a cycle interval time is set to t2; as the operation cycle progresses, based on the initial rotational speed c, the rotational speed of the first fan 21 and / or the roller brush 12 in a subsequent operation cycle increases by a change x compared to the rotational speed of the previous operation cycle.

[0052] Specifically, according to actual use, a processor module is provided in the dust collection component 10, which can control the second fan 11 or the roller brush 12 to perform different intermittent working states and speed change states. Preferably, during the dust collection process, there are multiple levels of dust collection intensity. During the dust collection process, the first fan 21 continues to operate, and the first fan 21 does not change the speed and intermittent operation. Under the first level of dust collection intensity, only the second fan 11 or the roller brush 12 is set to operate with a time t1 as an operation cycle, and the intermittent time is t2. In the first operation cycle, the initial speed of the second fan 11 or the roller brush 12 is set to c, and it runs for n cycles. As the operation cycle progresses, the speed of the second fan 11 or the roller brush 12 in the latter operation cycle increases by a change x compared with the previous operation cycle.

[0053] Similarly, under the second level of dust collection intensity, the second fan 11 and the roller brush 12 are set to run simultaneously, with a time t1 as an operation cycle and an interval time t2. In the first operation cycle, the initial speed of the second fan 11 or the roller brush 12 is set to c, and it runs for n cycles. As the operation cycles progress, the speed of the second fan 11 or the roller brush 12 in the latter operation cycle increases by a change x compared with the previous operation cycle.

[0054] Among them, the operating cycle time t1 at the first-level dust collection intensity and the second-level dust collection intensity is a specific setting value. According to the actual situation, the setting time t1 at the first-level dust collection intensity and the second-level dust collection intensity can be the same or different. The intermittent time t2, the initial speed c, the number of operating cycles n and the speed change x are the same.

[0055] In a specific dust collection process, under the first gear dust collection intensity, only the roller brush 12 is controlled to rotate, and the roller brush 12 is set to run at an initial speed c of 300r / min in the initial operation cycle. Since it is necessary to collect the residual debris 4 on the roller brush 12 during the initial dust collection process of this specific first gear dust collection intensity, the initial speed of the roller brush 12 needs to be set relatively low to ensure that the roller brush 12 can complete the dust collection of the debris 4 on the roller brush 12 within fewer operation cycles. Furthermore, the operation cycle time t1 is set to 30 seconds, and the intermittent time t2 is set to 10 seconds. As the operation cycle increases, the speed change x is set to 100r / min, and n=7 is set, that is, seven cycles are run to complete the first gear intensity dust collection. At the same time, it is determined whether the remaining amount of debris 4 in the roller brush 12 and the dust storage box 15 is zero. If it is determined to be yes, the dust collection operation is terminated. If it is determined to be no, the cycle returns to the first gear intensity dust collection operation.

[0056] Therefore, the processor module provided in the dust collection assembly 10 can control the second fan 11 or the roller brush 12 to perform different intermittent working states and speed change states. During the dust collection process, multiple levels of dust collection intensity can be set. Under different levels of dust collection intensity, the second fan 11 and the roller brush 12 can be controlled to operate separately or simultaneously according to the settings, and the speed and intermittent time can be changed, so as to flexibly adapt to different dust collection scenes and needs, and further optimize the dust collection effect.
