Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a guide structure of a multi-power dust collection system. BACKGROUND

[0002] At present, in the field of cleaning equipment, dust collection treasure is widely used as an auxiliary dust collection equipment of cleaning devices such as sweeping robots. Common dust collection treasures mostly adopt a single-power dust collection mode, that is, mainly rely on the suction force generated by the fan inside the dust collection treasure to suck out the dust in the dust box of the sweeping robot and collect it into the dust collection treasure. In this traditional single-power dust collection process, the dust collection air flow field is in a state of mostly laminar flow. Due to the characteristics of laminar flow, the wind direction is single and stable, and when dusting the dust box of the sweeping robot, the garbage located at the corner of the dust box is often difficult to be effectively sucked out.

[0003] And due to the difficulty of laminar flow to form enough disturbance and entrainment force in the corner area, part of the garbage remains in the corner 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 mainly laminar flow dust collection method gradually exposes its limitations, and it is difficult to meet the needs of users for efficient and thorough cleaning, so an innovative dust collection technology is needed to solve this problem, so as to improve the dust collection rate and improve the cleaning effect. CONTENT OF THE INVENTION

[0004] The purpose of the present application is to provide a guide structure of a multi-power dust collection system to improve the dust collection effect of cleaning equipment.

[0006] As a preferred, the first fan operates to generate a right-to-left airflow in the dust storage box, the roller brush rotates to generate a right-bottom-to-left-top airflow in the dust storage box, and the second fan operates to generate an up-down airflow in the dust storage box. The three airflows with different directions collide in the dust storage box to form a turbulent airflow. The airflow generated by the rotation of the roller brush has a greater flow rate than the airflow generated by the second fan, and the turbulent airflow finally carries the debris to the dust collection assembly.

[0007] As another preferred, the first air duct has a straight line structure, and the second air duct has a U-shaped structure.

[0008] Further preferably, the dust storage box is provided with an air inlet end and an air outlet end. The air inlet end is close to the side of the roller brush, and the air outlet end is close to the side of the dust collection assembly. The bottom plate includes a first flat section and a first arc section which are integrally arranged. The first flat section is attached to the bottom plane of the dust collection assembly and extends to the air outlet end. The first arc section extends to the air inlet end.

[0009] Further preferably, the side plate is connected to the bottom plate. The side plate includes a second flat section and a second arc section which are integrally arranged. The second flat section is connected to the first arc section, and the second arc section is connected to the first flat section. The first arc section is curved and lifted relative to the plane of the first flat section. The volume enclosed by the first arc section and the second flat section is smaller than the volume enclosed by the second arc section and the first flat section.

[0010] Further preferably, in the first air duct, the first arc section is provided with a first arc-shaped guide surface close to one side of 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 to 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 dust storage box air inlet end, 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 further includes a first stopper and a second stopper. The first stopper is arranged at the air inlet end, and the first stopper is movably connected to the first arc section. The second stopper is arranged at the air outlet end, and the second stopper is movably connected to the first flat section. The first stopper and the second stopper are spaced apart to allow the airflow to flow through the dust storage box from the air inlet end to the air outlet end and then enter the dust collection assembly.

[0013] Preferably, a working method of a flow guide structure of a multi-power dust collection system is provided, the flow guide structure of the multi-power dust collection system comprising a dust suction module and a dust collection module, the dust collection module controlling the start and stop of a first fan, and the dust suction module controlling the start and stop of a roller brush and a second fan, the working method comprising: step S10: controlling the first fan to run continuously to generate suction force for dust collection; step S20: while the first fan is running, controlling the roller brush and / or the second fan to run rotationally at a first preset parameter; step S30: determining whether the remaining amount of debris is zero; step S40: if the determination is yes, controlling the first fan, the roller brush and the second fan to stop running; if the determination is no, returning to step S20.

[0014] Further preferably, in step S20, the roller brush and / or the second fan run at an initial speed c; the roller brush and / or the second fan are controlled to run for n cycles, a single running cycle time is set as t1, and a cycle interval time is set as t2; with the running cycles passing, the speed of the first fan and / or the roller brush in the later running cycle is increased by a change amount x compared with the speed in the previous running cycle based on the initial speed c.

[0015] Compared with the prior art, the application has the following beneficial effects:

[0016] 1. In the dust collection process, the first fan generates air flow from right to left, the roller brush generates air flow from right down to left up, and the second fan generates air flow from bottom to top, the three air flows with different directions collide in the dust storage box to form turbulent flow, which can effectively bring the debris located at the corner of the dust storage box into the dust collection assembly, solving the problem that laminar flow cannot easily suck out the corner garbage in common single-power dust collection, thereby improving the overall dust collection efficiency.

[0017] 2. In the dust collection process, since the roller brush is in a rotating state, the air flow generated by the first fan and the air flow generated by the rotation of the roller brush not only help to form turbulent flow in the dust storage box to carry away debris, but also conveniently suck away the debris remaining on the roller brush during cleaning, realizing a certain degree of self-cleaning function of the roller brush, and reducing the situation that the cleaning effect of the roller brush is affected due to the accumulation of residual debris.

[0018] 3. If only the first fan and the second fan are running at the same time, due to the inconsistent flow direction of the air flow generated by them, the air flow generated by the second fan will affect the suction force generated by the first fan to some extent, and the overall dust collection suction force will be reduced to some extent. The application file adds the specific wind direction air flow generated by the rolling brush rotation, which changes the overall situation of the air flow. Since the air flow generated by the first fan and the air flow generated by the rolling brush rolling are in the same direction in the dust storage box, the influence of the different flow directions of the air flow generated by the second fan on the dust collection suction force is weakened, so that the turbulent flow generated by the collision of the three air flows can flow towards the dust collection assembly, improve the overall suction force, and ensure the smooth progress of the dust collection work.

DETAILED DESCRIPTION

[0030] Hereinafter, the present application will be further described in conjunction with specific embodiments, it should be noted that, in the absence of conflict, the following description of each embodiment or each technical feature can be combined with any other embodiment or technical feature to form a new embodiment.

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

[0033] The terms "include" and "have" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0034] In a preferred embodiment, referring to Figures 1 to 9The application provides a guide structure 11 of a multi-power dust collection system, comprising: a dust suction assembly 10 and a dust collection assembly 20, the dust suction assembly 10 is connected with the dust collection assembly 20, the dust collection assembly 20 is used for sucking up the debris 4 in a dust storage box 15 in the dust suction assembly 10, the dust collection assembly 20 is provided with a first fan 21, the dust suction assembly 10 is provided with a rolling brush 12 and a second fan 11, the dust suction assembly 10 is provided with the rolling brush 12; the first fan 21 runs to generate a flow from right to left in the dust storage box 15, the rolling brush 12 rotates to generate a flow from right to left in the dust storage box 15, the second fan 11 runs to generate a flow from bottom to top in the dust storage box 15, the three flows with different wind directions collide in the dust storage box 15 to form a turbulent flow, the flow speed generated by the rolling brush 12 is greater than the flow speed generated by the second fan 11, and finally the flow in the turbulent flow state carries the debris 4 to the dust collection assembly 20.

[0035] The dust suction assembly 10 is used for sucking up the debris 4, garbage and other objects in the outside world, so as to temporarily store in the dust storage box 15 of the dust suction assembly 10, and the process is a dust suction process. When the debris 4 in the dust storage box 15 accumulates to a certain degree, the dust collection assembly 20 needs to be used to empty the garbage in the dust storage box 15, so as to facilitate the next use of the dust suction assembly 10. Therefore, referring to Figure 4 If only the suction force in a single direction generated by the first fan 21 is relied on, it is difficult to suck the debris 4 and other objects in the corner part of the dust storage box 15 into the dust collection assembly 20.

[0036] Therefore, in the dust collection process, referring to Figure 2 the movement direction of the flow, the flow direction is indicated by a solid arrow, that is, during the operation of the first fan 21, the rolling brush 12 rotates synchronously, the flow generated by the first fan 21 flows from right to left in the cavity of the dust storage box 15, the flow generated by the rolling brush 12 rotates from right to left in the cavity of the dust storage box 15, and the dust suction assembly 10 is also provided with the second fan 11, the second fan 11 runs synchronously to generate a flow from bottom to top in the cavity of the dust storage box 15. The flow directions of the above three flows are all explanations of the movement trend of the flow, because the movement trends of the three flows are different, the three flows collide in the dust storage box 15 to generate a turbulent flow, so as to disturb the flow state of the flow flowing to the dust collection assembly 20. That is, the wind field flow channel in the dust storage box 15 is changed from the original single-direction laminar flow direction to the turbulent flow direction around multiple directions, that is Figure 3 and Figure 5 shown, at this time, the turbulent flow direction around multiple directions can effectively bring the debris 4 located at the corner position in the dust storage box 15 into the dust collection assembly 20.

[0037] Meanwhile, since the dust suction assembly 10 is in the front suction process, since the roller brush 12 is a cylindrical structure, and the roller brush 12 has a brush, a scraper and other structures, when the roller brush 12 rolls to clean the garbage debris 4, the brush on the roller brush 12 is also easy to stick with the garbage debris 4, and the debris 4 stuck on the roller brush 12 cannot be effectively brought into the dust storage box 15, so in the dust collection process, the rotation of the roller brush 12 cooperates with the suction force generated by the first fan 21, which can further effectively clean the debris 4 around the roller brush 12. The scraper is relatively V-shaped convex to the cylindrical surface of the roller brush 12, which can collect the debris 4 through the scraper when the roller brush 12 rotates during the dust suction process, and the air flow generated by the rotation of the scraper on the roller brush 12 during the dust collection process.

[0038] In some dust collection processes, either the second fan 11 or the roller brush 12 can be used alone, which can save a part of energy consumption under the premise of ensuring the air flow disturbance effect.

[0039] Preferably, the second fan 11 is operated in cooperation with the synchronous operation of the roller brush 12, and if the second fan 11 is operated alone in some related technologies, the suction force generated by the second fan 11 is repulsive to the suction force generated by the first fan 21, which can disturb the air flow in the dust storage box 15, but can reduce a part of the suction force generated by the first fan 21 to the dust storage box 15. Therefore, the second fan 11 is preferably operated in cooperation with the synchronous operation of the roller brush 12, and the rotating speed of the roller brush 12 during the dust collection process can be greater than the rotating speed of the roller brush 12 during the dust suction process, so that the air flow generated by the rotation of the roller brush 12 is greater than the air flow generated by the second fan 11, the air flow provided by the rotation of the roller brush 12 is consistent with the air flow generated by the suction force of the first fan 21, which can make up for the reduced suction force caused by the operation of the second fan 11 to a certain extent, and the air flow in the turbulent state finally carries the debris 4 to the dust collection assembly 20.

[0040] Further preferably, referring to Figure 2 , the guide structure 1 of the multi-power dust collection system further comprises 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 air 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, and the outlet of the second air duct is the air outlet of the second fan 11. The first air duct is sequentially communicated by the cavity where the roller brush 12 is located, the space of 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 in a straight line type structure. The second air duct is sequentially communicated 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 by the filter plate 16 and the pipeline where the second fan 11 is located, and the second air duct is in a U-shaped structure.

[0041] Therefore, in the first air duct, the flow direction of the air flow is into the opening cavity opened by the position of the roller brush 12, affected by the suction of the first fan 21, and then flows to the pipeline of the first fan 21 in the dust collection assembly 20 through the dust storage box 15 to be discharged from the air outlet of the first fan 21. In the second air duct, the flow direction of the air flow is into the opening cavity opened by the position of the roller brush 12, affected by the suction of the second fan 11, so that the air flow moves upward in the dust storage box 15 and is discharged through the filter plate 16. With the upward flowing trend of the air flow, the air flow flows toward the second fan 11, that is, flows upward, flows to the pipeline of the second fan 11, and is discharged from the air outlet.

[0042] Further preferably, the structure of the first air duct and the second air duct is described, and the internal structure of the dust storage box 15 corresponds to the structure of the first air duct and the second air duct. Therefore, the dust storage box 15 includes a bottom plate 151, as shown in 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 side of the roller brush 12, and the air outlet end 154 is close to the side of the dust collection assembly 20. The bottom plate 151 includes a first flat section 1511 and a first arc section 1512 which are integrally transitioned. The first flat section 1511 is attached to the bottom plane of the dust collection assembly 10 and extends to the air outlet end 154. The first arc section 1512 extends to the air inlet end 153.

[0043] Further preferably, as shown in Figure 7 , the dust storage box 15 further includes a side plate 152 connected to the bottom plate 151. The side plate 152 includes a second flat section 1521 and a second arc section 1522 which are integrally transitioned. The second flat section 1521 is connected to the first arc section 1512, and the second arc section 1522 is connected to the first flat section 1511 to allow the air flow in the first air duct to flow.

[0044] Preferably, the dust storage box 15 further includes a first stopper 13 and a second stopper 14. The first stopper 13 is disposed at the air inlet end 153 and is movably connected to the first arc section 1512. The second stopper 14 is disposed at the air outlet end 154 and is movably connected to the first flat section 1511. The first stopper 13 and the second stopper 14 are spaced apart to allow the air flow to enter the dust storage box 15 from the air inlet end 153 and enter the dust collection assembly 20 through the air outlet end 154.

[0045] The air inlet end 153 of the dust storage box 15 is larger than the air outlet end 154, and the air inlet end 153 gradually shrinks to the air outlet end 154 through the side plate 152, so as to ensure the flow rate of the air outlet end 154 and ensure the dust collection effect. At the same time, the second flat section 1521 of the side plate 152 is connected to one side of the air inlet end 153, so as to reduce the accumulation of the debris 4 in the dust storage box 15 from the air inlet end 153, and the second arc-shaped section 1522 can effectively improve the flow guiding effect of the airflow in the first air duct and reduce the airflow backflow in the dust storage box 15.

[0046] At the same time, referring to Figure 8 , the first arc-shaped section 1512 is curved and lifted relative to the plane of the first flat section 1511, and the volume surrounded by the connection between the first arc-shaped section 1512 and the second flat section 1521 is smaller than the volume surrounded by the second arc-shaped section 1522 and the first flat section 1511, which sacrifices part of the dust storage space on one side of the air inlet end 153, but further reduces the accumulation of the debris 4 on one side of the air inlet end 153, and the arc-shaped first arc-shaped section 1512 can guide the airflow flowing into the cavity opening of the roller brush 12, improve the airflow velocity, and thus improve the dust collection effect.

[0047] Preferably, in the first air duct, referring to Figure 8 , the first arc-shaped section 1512 is provided with a first arc-shaped guide surface 155 on the side close to the air inlet end 153, and the airflow enters the air inlet end 153 and is guided by the first arc-shaped guide surface 155 to flow to the air outlet end 154 along the extension direction of the bottom plate 151, so as to improve the flow effect of the airflow in the first air duct; similarly, referring to Figure 9 , the second arc-shaped section 1522 of the side plate 152 is provided with a second arc-shaped guide surface 156 at the position of the air outlet end 154, which has a certain converging effect on the airflow, so as to facilitate the airflow to flow to the outlet of the second stopper 14.

[0048] Further, Figure 7 , the assembly and setting relationship between the filter plate 16 and the dust storage box 15 is shown, the setting width of the air inlet of the second fan 11 is matched with the setting width of the air inlet end 153 of the dust storage 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, so that the filter plate 16 has a certain setting area, that is, the long side of the filter plate 16 is longer than the opening length of the air inlet end 153 of the dust storage box 15, and the short side of the filter plate 16 is as close to the side plate 152 of the dust storage box 15 as possible, so as to improve the filtering and air outlet effects, ensure that the dust storage 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 the air guide structure 1 of the multi-power dust collection system is provided, the air guide structure 1 of the multi-power dust collection system comprises 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. The working method comprises the following steps: step S10: controlling the first fan 21 to continuously run to generate suction force for dust collection; step S20: controlling the roller brush 12 and / or the second fan 11 to run at a first preset parameter while the first fan 21 is running; step S30: judging whether the remaining amount of debris 4 is zero; step S40: if the judgment is yes, controlling the first fan 21, the roller brush 12 and the second fan 11 to stop running; if the judgment is no, returning to step S20.

[0050] Preferably, the sensor module is arranged at the position of the dust storage box 15, and is used for sensing the remaining amount of debris 4 in the dust storage box 15. The diameter of the sensed debris 4 needs to be greater than a set diameter, so as to avoid the false detection of the sensor module by some dust with a too small diameter. Preferably, the sensor module is arranged at the position of the roller brush 12, and can synchronously detect the remaining amount of debris 4 on the roller brush 12 when the roller brush 12 and the first fan 21 are synchronously running. If the remaining amount of debris 4 in any one of the above (in the dust storage box 15 or on the roller brush 12) does not reach zero, the dust collection operation is still continuously performed by returning to step S20.

[0051] Further preferably, in step S20, the roller brush 12 and / or the second fan 11 run at an initial rotating speed c; the roller brush 12 and / or the second fan 11 run for n cycles, a single running cycle time is set as t1, and a cycle interval time is set as t2; with the running cycle going on, the rotating speed of the first fan 21 and / or the roller brush 12 in the later running cycle is increased by a change amount x compared with the rotating speed in the previous running cycle.

[0052] Specifically, according to the actual use, the dust suction assembly 10 is provided with a processor module, which can control the second fan 11 or the roller brush 12 to perform different intermittent working states and rotating speed changing states. Preferably, in the dust collection process, there are multiple dust collection intensities. The first fan 21 continuously runs in the dust collection process, and the rotating speed and intermittent working state of the first fan 21 do not change. In the first dust collection intensity, only any one of the second fan 11 or the roller brush 12 is set to run for a running cycle of time t1, and the intermittent time is t2. In the first running cycle, the initial rotating speed of the second fan 11 or the roller brush 12 is set as c, and runs for n cycles. With the running cycle going on, the rotating speed of the second fan 11 or the roller brush 12 in the later running cycle is increased by a change amount x compared with the rotating speed in the previous running cycle.

[0053] Similarly, at the second dust collection intensity, the second fan 11 and the roller brush 12 are set to run simultaneously, with time t1 as one running cycle and an interval time of t2. In the first running cycle, the initial speed of the second fan 11 or the roller brush 12 is set to c. After running n cycles, as the running cycle progresses, the speed of the second fan 11 or the roller brush 12 in each subsequent running cycle increases by a change amount x compared to the previous running cycle.

[0054] Among them, the operating cycle time t1 under the first dust collection intensity and the second dust collection intensity is a specific set value. Depending on the actual situation, the set time t1 under the first dust collection intensity and the second dust collection intensity can be the same or different. The same applies to the intermittent time t2, the initial speed c, the number of operating cycles n, and the speed change x.

[0055] In one specific dust collection process, at the first dust collection intensity, only the roller brush 12 is controlled to rotate. The roller brush 12 is set to run at an initial speed c of 300 r / min in the initial running cycle. Since the residual debris 4 on the roller brush 12 needs to be collected in the initial dust collection process of this specific first dust collection intensity, the initial speed of the roller brush 12 needs to be set low to ensure that the roller brush 12 can complete the collection of debris 4 on the roller brush 12 in a shorter running cycle. Furthermore, the running cycle time t1 is set to 30 seconds, the interval time t2 is set to 10 seconds, and the speed change x is set to 100 r / min as the running cycle increases. n = 7, that is, seven cycles are run to complete the first 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 collection box 15 is zero. If the determination is yes, the dust collection operation ends. If the determination is no, the cycle of the first intensity dust collection operation is returned.

[0056] Therefore, the processor module within the dust collection assembly 10 can control the second fan 11 or the roller brush 12 to operate in different intermittent states and with varying speeds. Multiple dust collection intensities can be set during the dust collection process. Under different intensities, the second fan 11 and roller brush 12 can be controlled to operate individually or simultaneously, and the speed and intermittent time can be varied, thus flexibly adapting to different dust collection scenarios and needs, further optimizing the dust collection effect.

[0057] Furthermore, participate Figure 10 The dust collection component 20 is specifically a dust collection box 2 structure, and the dust suction component 10 is specifically a sweeper 3.
