Sweeping machine

Abstract

The application provides a sweeper, which comprises a frame, a dust collecting box, a fan, a first dust suction part and a second dust suction part. Since the distance between the dust suction port of the first dust suction part and the cleaning surface is greater than the distance between the dust suction port of the second dust suction part and the cleaning surface, the first dust suction part can suck the first type of garbage during the cleaning process. When the dust suction port of the second dust suction part passes through the second type of garbage, the distance between the dust suction port and the cleaning surface first increases, so that the second type of garbage enters the dust suction port of the second dust suction part and then the distance between the second type of garbage and the cleaning surface returns to normal. The second dust suction part can suck the second type of garbage. Therefore, two dust suction ports are arranged to suck different types of garbage, which can avoid the problem of poor cleaning effect caused by the long or short distance between the dust suction port and the ground, and greatly improves the cleaning efficiency.

Description

Technical Field

[0001] This invention relates to the field of cleaning machine technology, and more particularly to a sweeper. Background Technology

[0002] To reduce the workload of floor cleaning for users, robotic vacuum cleaners are widely used in various places. For example, they can be used in shopping malls and homes. Robotic vacuum cleaners can remove dust, paper scraps, and other debris from the floor and collect them in their dustbin to prevent secondary pollution. They rely on the airflow generated by an internal fan to create negative pressure relative to the floor, sucking debris from the floor into the dustbin. For heavier debris (such as soybeans, black beans, and other grains, or small stones), if the suction port is too far from the floor, the negative pressure effect will be insufficient to lift it; if the suction port is too close, large debris, such as paper or even lint, may be blocked outside the suction port and cannot be cleaned. Summary of the Invention

[0003] The main objective of this invention is to provide a sweeping machine that solves the technical problem in the prior art where the suction port is too far or too close to the ground, resulting in poor cleaning performance.

[0004] The present invention proposes the following technical solution:

[0005] A sweeping machine, the sweeping machine comprising:

[0006] frame;

[0007] A dust collection box is installed inside the frame;

[0008] A fan is installed inside the frame and communicates with the dust collection box;

[0009] The first dust-collecting component is installed inside the dust collection box. The dust-collecting port of the first dust-collecting component passes through the bottom of the frame, so that the outside world is connected to the dust collection box, and is used to collect the first type of garbage.

[0010] The second dust collection component is installed inside the dust collection box. The suction port of the second dust collection component is inserted through the bottom of the frame, so that the outside world is connected to the dust collection box, and it is used to suck up the second type of waste.

[0011] In this process, the distance between the suction port of the first vacuum cleaner and the cleaning surface is greater than the distance between the suction port of the second vacuum cleaner and the cleaning surface. During the cleaning process, the first vacuum cleaner sucks up the first type of waste. When the suction port of the second vacuum cleaner passes through the second type of waste, the distance between it and the cleaning surface first increases, allowing the second type of waste to enter the suction port of the second vacuum cleaner. Then, the distance between it and the cleaning surface returns to normal, and the second vacuum cleaner sucks up the second type of waste.

[0012] Furthermore, the second suction port is rotatably connected to the dust collection box. When the suction port of the second suction component passes through the second type of waste, the suction port of the second suction component flips away from the cleaning surface under the resistance of the second type of waste, allowing the second type of waste to enter the suction port of the second suction component. Then, under the action of gravity, the suction port of the second suction component flips towards the cleaning surface, and the second suction component sucks up the second type of waste.

[0013] Furthermore, the second vacuuming component is movably connected to the bottom surface of the frame via a flexible connector.

[0014] Furthermore, the first dust-collecting component includes a first jet area and a first dust-inlet area, which cooperate to form the dust-collecting port of the first dust-collecting component. The second dust-collecting component includes a second jet area and a second dust-inlet area, which cooperate to form the dust-collecting port of the second dust-collecting component. The air outlet of the fan, the jet area, the first jet area, the first dust-inlet area, the dust-inlet area, and the air inlet of the fan are sequentially connected. The air outlet of the fan, the jet area, the second jet area, the second dust-inlet area, the dust-inlet area, and the air inlet of the fan are sequentially connected.

[0015] Furthermore, the first dust collection component is provided with a first partition, which divides the internal space of the first dust collection component into a first jet zone and a first dust inlet zone. A first through hole is provided on the side of the first jet zone, which connects the jet zone and the first jet zone.

[0016] Furthermore, the edge of the suction port of the second suction component is parallel to the cleaning surface.

[0017] Furthermore, the second dust collection component includes a cylindrical portion rotatably connected to the dust collection box and a housing connected to the cylindrical portion. A first baffle is provided inside the cylindrical portion along its radial direction, dividing the cylindrical portion into a first connecting region and a second connecting region. A second baffle is provided inside the housing along the axial direction of the cylindrical portion, dividing the housing into a third connecting region and a fourth connecting region. The first connecting region and the third connecting region communicate to form the second jet region, and the second connecting region and the fourth connecting region communicate to form the second dust inlet region.

[0018] Furthermore, a gap is maintained between the side of the second baffle away from the cylindrical portion and the plane containing the suction port of the second vacuum component. When the suction port of the second vacuum component is in contact with the cleaning surface, the gap connects the third connecting region and the fourth connecting region.

[0019] Furthermore, the dust collection box is provided with a first support member and a second support member, and the two ends of the cylindrical part pass through the first support member and the second support member respectively and are rotatably connected to the first support member and the second support member.

[0020] Furthermore, the first baffle is centrally located within the cylindrical portion, and the second baffle is centrally located within the housing.

[0021] Furthermore, the suction port of the first vacuuming component is located in front of the suction port of the second vacuuming component, wherein the direction of the sweeper's forward movement is defined as forward.

[0022] This invention provides a sweeping machine, including a frame, a dust collection box, a fan, a first suction component, and a second suction component. Because the distance between the suction port of the first suction component and the cleaning surface is greater than the distance between the suction port of the second suction component and the cleaning surface, during the cleaning process, the first suction component sucks up the first type of debris. When the suction port of the second suction component passes through the second type of debris, the distance between it and the cleaning surface first increases, allowing the second type of debris to enter the suction port of the second suction component. After this, the distance between it and the cleaning surface returns to normal, and the second suction component sucks up the second type of debris. Therefore, by setting two suction ports to suck up different types of debris, the problem of poor cleaning effect caused by suction ports being too far or too close to the ground is avoided, greatly improving cleaning efficiency.

[0036] Reference Figures 1 to 6 A sweeping machine, comprising: a frame 1; a dust collection box 2 disposed within the frame 1; a fan 3 disposed within the frame 1 and communicating with the dust collection box 2; a first suction component 4 installed within the dust collection box 2, the suction port of the first suction component 4 extending through the bottom of the frame 1 to connect the outside to the dust collection box 2, for suctioning first-type waste; and a second suction component 5 installed within the dust collection box 2, the suction port of the second suction component 5 extending through the bottom of the frame 1 to connect the outside to the dust collection box 2. The dustbin 2 is connected and used to suck up the second type of waste; wherein, the distance between the suction port of the first suction component 4 and the cleaning surface is greater than the distance between the suction port of the second suction component 5 and the cleaning surface. During the cleaning process, the first suction component 4 sucks up the first type of waste; when the suction port of the second suction component 5 passes through the second type of waste, the distance between it and the cleaning surface first increases, allowing the second type of waste to enter the suction port of the second suction component 5, and then the distance between it and the cleaning surface returns to normal, and the second suction component 5 sucks up the second type of waste.

[0037] In this implementation, specifically, the first type of waste consists of bulky waste (such as paper, lint, and lint balls), and the second type consists of heavier waste (such as soybeans, black beans, and other grains, and stone particles). In one feasible implementation, two fans 3 are provided, specifically a first fan and a second fan (not shown in the accompanying drawings). Correspondingly, two dust collection boxes 2 are also provided, specifically a first dust collection box 2 and a second dust collection box 2 (not shown in the accompanying drawings). A first suction component 4 is placed inside the first dust collection box 2, and a second suction component 5 is placed inside the second dust collection box 2. In this embodiment, the first fan is a suction fan, the second fan is a blower, and the first suction component 4 is located in front of the second suction component 5. In this embodiment, the direction of the sweeper's movement is defined as forward. Since the suction power of the first suction component 4 is provided by the first fan, the distance between the suction port of the first suction component 4 and the cleaning surface cannot be too close to the ground, otherwise the cleaning surface may be damaged due to excessive negative pressure or the sweeper may be difficult to move due to excessive suction power. Furthermore, since the suction power of the second vacuuming component 5 is provided by the second fan, which is a blower, there is no problem of damaging the cleaning surface due to excessive negative pressure or making the sweeper difficult to move due to excessive suction. Therefore, the second vacuuming component 5 requires a special design to work in conjunction with the second fan, and the specific structure of the second vacuuming component 5 will be described in detail below. Thus, the suction port of the second vacuuming component 5 can be closer to the ground than the suction port of the first vacuuming component 4. Preferably, the suction port of the second vacuuming component 5 can be completely flush with the ground. The specific working principle of this embodiment is described below. Figure 7 ,like Figure 7 As shown, during the cleaning process, if there is type 1 debris on the surface to be cleaned, it will be sucked into the first dust collection box 2 due to the suction of the first suction component 4. If there is type 2 debris on the surface, the suction port of the first suction component 4 is farther from the ground, so the negative pressure effect will not be sufficient to lift the type 2 debris. Therefore, this debris will remain in place, and the sweeper will continue to move forward. Since the second suction port in this embodiment is completely in contact with the ground, type 2 debris will inevitably come into contact with the leading edge of the suction port of the second suction component 5. Under the resistance of type 2 debris, the suction port of the second suction component 5 will move upward, increasing the distance between the suction port and the cleaning surface. Specifically, the second suction component 5 can be driven upward by a drive device installed in the frame 1 to increase the distance between the suction port and the cleaning surface. As the sweeper continues to move forward until the second type of debris is completely covered by the suction port, the second suction component 5 returns to a state of contact with the cleaning surface, and under the action of the second fan, the second type of debris is sucked into the second dust collection box 2.

[0038] To ensure complete contact between the cleaning surface and the suction port of the second suction component 5, the edge of the suction port of the second suction component 5 is parallel to the cleaning surface, further improving suction efficiency. In the above embodiment, by providing two suction ports to collect different types of debris, the problem of poor cleaning results caused by suction ports being too far or too close to the ground is avoided, greatly improving cleaning efficiency and achieving excellent cleaning results.

[0039] In one feasible implementation, the suction port of the second vacuum cleaner 5 is rotatably connected to the dust collection box 2. When the suction port of the second vacuum cleaner 5 passes through the second type of waste, the suction port of the second vacuum cleaner 5 flips away from the cleaning surface under the resistance of the second type of waste, allowing the second type of waste to enter the suction port of the second vacuum cleaner 5. Then, under the action of gravity, the suction port of the second vacuum cleaner 5 flips towards the cleaning surface, and the second vacuum cleaner 5 sucks up the second type of waste. In this embodiment, the flipping of the second vacuum cleaner 5 can be driven by a driving device (not shown in the figures). When the second type of waste comes into contact with the leading edge of the suction port of the second vacuum cleaner 5, the driving device receives a signal that the second vacuum cleaner 5 needs to be flipped and starts. Since the driving device drives the second vacuum cleaner 5 to flip, the distance between the suction port and the ground increases, so the second type of waste will not be pushed forward by the second vacuum cleaner 5 and will not fall into the range of the suction port. Preferably, the second vacuum cleaner 5 can also be flipped by the resistance of the second type of waste.

[0040] In one feasible embodiment, the second suction component 5 is movably connected to the bottom surface of the frame 1 via a flexible connector 11. The connector 11 is made of an elastic material and has soft elasticity. This arrangement allows the second suction component 5 to rotate while ensuring the airtightness of the dust collection box 2.

[0041] In one feasible embodiment, the dust collection box 2 includes a jet region 21 and a dust inlet region 22. The first suction component 4 includes a first jet region 401 and a first dust inlet region 402, which cooperate to form the suction port of the first suction component 4. The second suction component 5 includes a second jet region and a second dust inlet region, which cooperate to form the suction port of the second suction component 5. The air outlet of the fan 3, the jet region 21, the first jet region 401, the first dust inlet region 402, the dust inlet region 22, and the air inlet of the fan are sequentially connected. In this embodiment, only one dust collection box 2 and one fan 3 are used, achieving resource integration and saving, and avoiding the use of too many mechanical parts that would make the overall body of the sweeper too large and heavy.

[0042] It is worth mentioning that in this embodiment, the fan 3 is also connected to the air vent on the dust collection box 2. The suction force generated by the fan 3 is transmitted to the dust collection box 2 through the air vent. The garbage is sucked into the dust collection box 2 through the dust inlet area corresponding to the suction component (e.g., the first dust inlet area 402 of the first suction component, and / or the second dust inlet area of ​​the second suction component). At the same time, the air force discharged from the rear end of the fan 3 is guided into the jet area 21 of the dust collection box 2 through the air duct, and is ejected through the jet area of ​​the suction component (e.g., the first jet area 401 of the first suction component, and / or the second jet area of ​​the second suction component) to push the garbage. The garbage is then guided into the dust collection box 2 by the air force superimposed on the suction area of ​​the suction component from the air duct. In fact, a single fan can achieve a dual force of suction and blowing, which is especially suitable for heavier garbage.

[0043] Specifically, the first vacuum cleaner 4 is provided with a first partition 40, which divides the internal space of the first vacuum cleaner 4 into a first jet zone 401 and a first dust inlet zone 402. A first through hole 41 is provided on the side of the first jet zone 401, which connects the jet zone 21 and the first jet zone 402. Since the airflow in the jet zone 21 is directed out from the air outlet of the fan 3, the airflow velocity is relatively high. Because it maintains an appropriate distance from the ground, the jet zone 21 is largely sealed off, and the airflow can only flow into the dust inlet zone 22. This can accelerate the work done on the garbage in the dust inlet zone, thereby accelerating the absorption of garbage and improving the absorption rate. The specific process of the first type of waste being sucked up is as follows: the airflow is ejected from the air outlet of the fan 3, flows through the jet area 21 and enters the ground of the first jet area 401, blowing up the first type of waste in the first jet area 401 and the first dust inlet area 402. The air inlet of the fan 3 carries the waste in the first jet area 401 and the first dust inlet area 402 into the dust inlet area 22, where the filter screen in the dust inlet area 22 intercepts the waste.

[0044] In one feasible embodiment, the second dust collection component 5 includes a cylindrical portion 511 rotatably connected to the dust collection box 2 and a housing 512 connected to the cylindrical portion 511. A first baffle 51 is provided inside the cylindrical portion 511 along its radial direction, dividing the cylindrical portion 511 into a first connecting region 521 and a second connecting region 522. A second baffle 52 is provided inside the housing 512 along the axial direction of the cylindrical portion 511, dividing the housing 512 into a third connecting region 501 and a fourth connecting region 502. The first connecting region 521 and the third connecting region 501 communicate to form the second jet region, and the second connecting region 522 and the fourth connecting region 502 communicate to form the second dust inlet region. The specific process of the second type of waste being sucked up is as follows: airflow is ejected from the outlet of the fan 3, flows through the jet area 21 and enters the ground of the second jet area, blowing up the second type of waste located in the second jet area and the second dust inlet area. The waste in the second jet area and the second dust inlet area is then carried by the inlet of the fan 3 into the dust inlet area 22, where the filter screen in the dust inlet area 22 traps the waste. Since the first baffle 51 is set in the same direction as the radial direction of the cylindrical part 511 and the second baffle 52 is set in the same direction as the cylindrical part 511, the orientations of the first baffle 51 and the second baffle 52 are perpendicular to each other. The first baffle 51 divides the cylindrical part 511 into left and right sections, that is, the first baffle 51 divides the cylindrical part 511 into a first connecting area 521 and a second connecting area 522. The cylindrical portion 511 is divided into left and right sections by the first baffle 51, facilitating the rotatable connection between the second suction component 5 and the dust collection box 2, while allowing the air inlet and outlet ports between the cylindrical portion 511 and the housing 512 to be distributed on the corresponding half of the cylindrical portion 511. The second baffle 52 divides the housing 512 into front and rear sections, reducing the lateral length of the suction port, which helps to cover and absorb more debris in the passage area. The specific design of the second suction component optimizes the structural layout, reduces the space occupied by the components, and allows for simultaneous blowing and suction functions on a single suction component, making the second suction component compact and lightweight while improving the absorption effect of debris.

[0045] Furthermore, a gap is maintained between the side of the second baffle 52 away from the cylindrical portion 511 and the plane containing the edge of the suction port of the second suction component 5. When the suction port of the second suction component 5 is in contact with the cleaning surface, the gap connects the third connecting region 501 and the fourth connecting region 502. The third connecting region 501 and the fourth connecting region 502 are connected via the gap. The suction force of the fourth connecting region 502 is generated by the suction force of the fan 3. In addition, the air blown out of the third connecting region 501, after being turned through the narrow gap, also enters the fourth connecting region 502, producing a combined airflow effect. Moreover, at the gap, due to the reduced space, the air blown out of the air outlet of the third connecting region 501 is compressed by the space, forming a higher pressure airflow that quickly rushes into the fourth connecting region 502, further strengthening the suction force there.

[0046] Furthermore, the dust collection box 2 is provided with a first support member 201 and a second support member 202. The two ends of the cylindrical portion 511 pass through the first support member 201 and the second support member 202 respectively and are rotatably connected to them. The two ends of the cylindrical portion 511 are one end of the first communicating region 521 and one end of the second communicating region 522, respectively. The first support member 201 can also be used to divide the dust collection box 2 into a jet region 21 and a dust inlet region 22. The above is only one embodiment of the rotatable connection between the second suction component 5 and the dust collection box 2; other embodiments that allow the second suction component 5 to be rotatably connected to the dust collection box 2 should be within the scope of protection of this application. In another feasible embodiment, the second suction component 5 and the dust collection box 2 can be rotatably connected via a hollow rotating shaft.

[0047] Furthermore, the first baffle 51 is centrally located within the cylindrical portion 511, and the second baffle 52 is centrally located within the housing 512. This arrangement ensures a balance between the airflow from the third connecting region 501 and the suction force from the fourth connecting region 502, thereby maximizing the gas flow rate within the second suction component 5.

[0048] Furthermore, the suction port of the first vacuum cleaner 4 is located in front of the suction port of the second vacuum cleaner 5, wherein the direction in which the sweeper moves forward is defined as forward.

[0049] In the aforementioned embodiments, the various components (such as the drive unit and fan) of the sweeper are controlled by a control board located within the sweeper. Each component is connected to and driven by the control board. This embodiment is not limited to any particular method of sending control commands to the control board. Specifically, it can employ existing technologies such as button control, remote control, intelligent control, or remote control. Those skilled in the art can apply existing control methods to this embodiment based on actual needs, which will not be elaborated upon here.

[0050] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
