Description

TECHNICAL FIELD

[0001] The present application relates to a waste collection module, in particular to a dry-wet separation waste collection module and a sweeping robot using the same. BACKGROUND

[0002] The current dry-wet dual-purpose dust collector can simultaneously suck solid waste such as sewage, dust, paper scraps, and glass on the ground into the dust collection barrel during the garbage cleaning operation. Since it does not need to avoid the sewage area, it can improve the convenience of the user during the garbage cleaning operation.

[0003] However, since the above-mentioned dry-wet dual-purpose dust collector cannot separate sewage and solid waste, sewage and solid waste are collected and mixed in the same dust collection barrel. SUMMARY

[0004] Based on the above design, the dust collection barrel is easily filled, so the user needs to clean the dust collection barrel before continuing to use the dry-wet dual-purpose dust collector for garbage cleaning operation. Since the above-mentioned cleaning frequency is frequent, there is still room for improvement in terms of use convenience.

[0005] In addition, the water in the garbage will also affect the efficiency of garbage disposal, for example, the water in the garbage needs to be filtered out and then poured into the sewage pipe before subsequent garbage disposal operation. Such a process will increase the garbage disposal time, and if the dry-wet dual-purpose dust collector does not have a water separation and filtration structure, it will generate a problem of reducing the service life of the air suction equipment due to moisture corrosion.

[0006] To solve the above problems, the purpose of the present application is to provide a dry-wet separation waste collection module, comprising: a cyclone collection barrel having an axis, a circular portion, and a tapered portion formed with a plurality of holes; an air inlet coupled with the circular portion and configured to suck waste containing water and / or solid pieces based on cyclone power; an air outlet disposed on the axis and configured to be coupled with a suction source to generate the cyclone power; a material outlet formed at the end of the tapered portion; a water collection cover covering the outside of the tapered portion and forming a water collection chamber with the tapered portion; and a water outlet coupled with the water collection chamber; wherein when the waste is driven by the cyclone power through the tapered portion, the water in the waste is discharged to the water collection chamber in a centrifugal manner through the plurality of holes, and the water in the water collection chamber is discharged by the water outlet, and the solid pieces in the waste are discharged by the material outlet.

[0007] In some embodiments, further comprising a flow guide spiral portion distributed in the circular portion and the tapered portion, the flow guide spiral portion is configured to increase the cyclone intensity.

[0008] In some embodiments, the waste collection module is further coupled to a water collection tank, the waste collection module is coupled to the water collection tank through the water outlet, and the water collection tank is configured to collect water in the waste.

[0009] In some embodiments, the water collection tank is further provided with a sensor to sense the amount of water collected in the waste.

[0010] In some embodiments, a sealing gasket is provided between the water outlet and the water collection tank.

[0011] In some embodiments, the waste collection module is further coupled to a water collection tank, the waste collection module is coupled to the water collection tank through the water outlet, and the water collection tank is configured to collect water in the waste.

[0012] In some embodiments, the water collection tank is further provided with a sensor to sense the amount of water collected in the waste.

[0013] In some embodiments, the water outlet and the water collection tank are connected through a water outlet channel to transport water in the waste.

[0014] In some embodiments, a sealing gasket is provided between the water outlet and the water collection tank.

[0015] In some embodiments, the inner diameter of the circular portion is greater than the inner diameter of the tapered portion.

[0016] To solve the above problems, the purpose of the present application is to provide a sweeping robot including a dry-wet separation waste collection module.

[0017] In summary, the waste collection module and the sweeping robot of the present application use the cyclone power generated by the air suction source (i.e. air suction equipment) to suck in the waste, increase the cyclone intensity by the flow guide spiral portion, and separate the water or liquid in the waste quickly into the water collection chamber by centrifugal force. The water or liquid in the water collection chamber can be discharged to the water collection tank through the water outlet, and the solid pieces in the waste can be discharged to the object collection tank along the flow guide spiral portion through the object outlet, thereby completing the dry-wet separation process of the waste. Since the moisture in the air discharged by the waste collection module is greatly reduced, the problem of corrosion of the air suction equipment due to moisture and reduction of service life can be solved. In addition, the sweeping robot of the present application can be configured with a water collection tank and an object collection tank to improve the collection capacity of the waste, and the cleaning frequency can be reduced by replacing the water collection tank or the object collection tank. Furthermore, after dry-wet separation of the waste, the water collection tank and the object collection tank can be more conveniently cleaned, the cleaning time is shortened, and the cleaning efficiency is greatly improved.

[0044] 105 waste collection module DETAILED DESCRIPTION

[0045] The "water" in the waste of the embodiments of the present application can refer to a liquid, and is not limited to the meaning that the waste needs to contain clean water or sewage. Therefore, the following description is exemplified by "water", but is not limited thereto.

[0046] Please refer to Figure 1A is a structural schematic diagram of a waste collection module 100 of the embodiments of the present application. The waste collection module 100 can include a cyclone collection tank 10, an air inlet 20, an air outlet 22, a material outlet 28, a water collection cover 26, and a water outlet 32. In the embodiments, the structural features of the cyclone collection tank 10, the air inlet 20, the air outlet 22, the material outlet 28, the water collection cover 26, and the water outlet 32 can be shapes required to be achieved by using a mold and an injection molding technology, but are not limited thereto. In other embodiments, other processing methods such as granulation, extrusion molding, stamping, and the like can be used to achieve the required shapes. The above components can be coupled to each other by using an integral molding method, so as to improve the convenience and efficiency of manufacturing, or can be coupled to each other by using other fixing methods such as assembly, buckling, adhesion, and / or locking, so as to improve the flexibility of component maintenance and the convenience of component replacement.

[0047] The cyclone collection tank 10 can have an axis 11, a circular portion 12, and a tapered portion 14 formed with a plurality of holes 141. The cyclone collection tank 10 can be roughly divided into an upper section (not marked in the figure), a middle section (not marked in the figure), and a lower section (not marked in the figure) along the direction of the axis 11.

[0048] The axis 11 is located at the center of the circular portion 12. The circular portion 12 is located in the upper section of the cyclone collection tank 10. The appearance of the circular portion 12 is roughly cylindrical.

[0049] The tapered portion 14 has a tapered structure that gradually narrows in the direction of the axis 11 toward the lower section of the cyclone collection barrel 10. In the partial structure of the tapered portion 14 covered by the collection cover 26, a plurality of holes 141 are formed. The number, shape, distribution position, and distribution density of the holes 141 can be adjusted or changed according to design requirements. In addition, in the present embodiment, the inner diameter of the circular portion 12 can be greater than or equal to the inner diameter of the tapered portion 14, but is not limited thereto. In other embodiments, the inner diameter of the circular portion 12 can also be less than the inner diameter of the tapered portion 14.

[0050] One end of the air inlet 20 can be coupled with the circular portion 12. The air inlet 20 is generally disposed in the tangential direction of the circular portion 12. The appearance of the air inlet 20 is generally in the shape of a circular tube. The other end of the air inlet 20 can be designed to have a structure feature (e.g., internal thread, external thread, buckle, plug, etc.) for engaging other components. The air inlet 20 is configured to suck in waste (not shown in the figure) containing water or other liquids, waste containing solid pieces (e.g., powder, leaves, plastic, dust, silt, hair, paper, glass, and / or metal, etc.), or waste containing both water and solid pieces based on the cyclone power.

[0051] The air outlet 22 is disposed on the axis 11. The appearance of the air outlet 22 is generally in the shape of a circular tube. One end of the air outlet 22 can be coupled with the circular portion 12 and penetrate into the interior of the cyclone collection barrel 10. The other end of the air outlet 22 can protrude from the top surface of the circular portion 12 and can be designed to have a structure feature (e.g., internal thread, external thread, buckle, plug, etc.) for engaging other components. The air outlet 22 is configured to be coupled with a suction source (e.g., a suction device, a motor, etc.) to generate the cyclone power.

[0052] The following describes the operating principle of the waste collection module 100.

[0053] When the suction source starts to operate, the cyclone power can be generated, so that air can be sucked into the air inlet 20 of the waste collection module 100 to form an air flow. When the air flow passes through the circular portion 12, the air flow can generate a cyclone in the interior of the waste collection module 100, and be discharged through the air outlet 22.

[0054] When the waste is sucked into the air inlet 20 by the aforementioned cyclone power, the waste can rotate downward along the direction of the cyclone. The aforementioned waste can contain water and / or solid pieces.

[0055] When the waste passes through the tapered portion 14, the water in the waste is discharged to the collection chamber 30 through the plurality of holes 141 on the tapered portion 14 in a centrifugal manner, and the aforementioned water discharged into the collection chamber 30 through the holes 141 is collected in the collection chamber 30 and then discharged through the drain 32, thereby completing the process of "wet separation" of the waste.

[0056] The solid pieces in the waste are spun in a centrifugal manner towards the lower section of the waste collection module 100 (e.g. the direction of the discharge outlet 28), and most of the solid pieces are blocked by the inner wall surface of the tapered section 14 due to the inability to pass through the holes 141 on the tapered section 14. The waste blocked by the inner wall surface of the tapered section 14 can continue to spin downwards along the cyclone direction. Finally, the solid pieces in the waste are discharged through the discharge outlet 28, thereby completing the process of "dry separation" of the waste. In this way, the waste collection module 100 that sucks in the waste can effectively perform "wet separation" and "dry separation", so that the moisture in the air discharged through the air outlet 22 is greatly reduced, thereby improving the problem of corrosion due to moisture in the existing air suction equipment and reducing the service life.

[0057] Please refer to Figure 1B , which shows the structural schematic diagram of the waste collection module 105 of another embodiment of the present application. Figure 1B The embodiment of Figure 1A is different from the embodiment of Figure 1B The waste collection module 105 further comprises a flow guide spiral section 13. In the present embodiment, the partial structure of the flow guide spiral section 13 can be seen from the upper surface of the circular section 12. More specifically, at the coupling between the air inlet 20 and the circular section 12, the upper surface of the circular section 12 is designed with a spiral structure (i.e. the partial structure of the flow guide spiral section 13) extending downwards in the direction of the axis 11 towards the discharge outlet 28. The spiral structure design can make the air sucked in by the air inlet 20 quickly and directly flow downwards, and can reduce the phenomenon of turbulence between the coupling between the air inlet 20 and the circular section 12, thereby improving the cyclone efficiency inside the cyclone collection barrel 10.

[0058] The flow guide spiral section 13 can be a sheet-like spiral structure, but is not limited thereto. The flow guide spiral section 13 is formed inside the cyclone collection barrel 10. The flow guide spiral section 13 can be distributed in the circular section 12 and the tapered section 14. The flow guide spiral section 13 is configured to increase the cyclone intensity. More specifically, the flow guide spiral section 13 can guide the cyclone, reduce the turbulence phenomenon, and increase the cyclone intensity, centrifugal force, thereby improving the cyclone efficiency inside the cyclone collection barrel 10. In addition, since the flow guide spiral section 13 can enhance the centrifugal force, when water passes through the flow guide spiral section 13, it can be centrifugally discharged more quickly. In other words, the flow guide spiral section 13 can also increase the drainage efficiency.

[0059] In the present embodiment, the helical structures in the flow guide helix 13 are distributed in the circular portion 12 and the tapered portion 14 in an equidistant manner. In other embodiments, the helical structures in the flow guide helix 13 are distributed in the circular portion 12 and the tapered portion 14 in a non-equidistant manner. For example, the aforementioned helical structures can be distributed in the upper section of the cyclone collection barrel 10 in a first pitch distance, and in the middle section and lower section of the cyclone collection barrel 10 in a second pitch distance smaller than the first pitch distance, but not limited thereto. By changing the pitch distance of the helical structures in the flow guide helix 13, the cyclone efficiency inside the cyclone collection barrel 10 can be adjusted accordingly. In other words, the flow guide helix 13 can be configured to increase the cyclone intensity. In addition, Figure 1B the remaining structures of the present embodiment are the same as or similar to those of Figure 1A the embodiment of the present application, and will not be described herein again.

[0060] The operation principle of the waste collection module 105 is described as follows.

[0061] When the air suction source starts to operate, a cyclone power can be generated, so that air can be sucked from the air inlet 20 of the waste collection module 105 to form an air flow. When the air flow passes through the flow guide helix 13, a cyclone can be generated inside the waste collection module 105, and the air flow can be discharged from the air outlet 22.

[0062] When the waste is sucked from the air inlet 20 by the aforementioned cyclone power, the waste can rotate downward along the helical direction of the flow guide helix 13. The aforementioned waste can include water and / or solid pieces.

[0063] When the waste passes through the tapered portion 14, the water in the waste is discharged to the water collection chamber 30 through the plurality of holes 141 on the tapered portion 14 in a centrifugal manner, and the aforementioned water discharged to the water collection chamber 30 through the holes 141 is collected in the water collection chamber 30 and then discharged through the water outlet 32, thereby completing the process of “wet separation” of the waste.

[0064] The solid pieces in the waste rotate in a centrifugal manner to the direction of the lower section of the waste collection module 105 (for example, the direction of the waste outlet 28), and most of the solid pieces are blocked by the inner wall surface of the tapered portion 14 because they cannot pass through the holes 141 on the tapered portion 14. The aforementioned waste blocked by the inner wall surface of the tapered portion 14 can continue to rotate downward along the flow guide helix 13. Finally, the solid pieces in the waste are discharged through the waste outlet 28, thereby completing the process of “dry separation” of the waste. In this way, the waste collection module 105 that sucks in the waste can effectively perform “wet separation” and “dry separation”, so that the moisture in the air discharged through the air outlet 22 is greatly reduced, thereby improving the problem of corrosion due to moisture in the existing air suction equipment and reducing the service life.

[0065] Please refer to Figure 2Fig. 6 is a top view showing the waste collection module 105 according to another embodiment of the present application. In Figure 2 In Fig. 6, it can be seen more clearly that the air inlet 20 is disposed substantially in the tangential direction of the circular portion 12. The appearance of the water collecting cover 26 is substantially cylindrical, but is not limited thereto. The water outlet 32 is disposed at one side of the water collecting cover 26. In the present embodiment, the number of the air inlet 20 and the water outlet 32 is one, respectively. In other embodiments, the number of the air inlet 20 and the water outlet 32 can be increased according to design requirements. In other embodiments, the water outlet 32 can also be disposed in the tangential direction of the water collecting cover 26, that is, the positions of the air inlet 20 and the water outlet 32 can be adjusted according to design requirements.

[0066] Please refer to Figure 3 Fig. 7 is a cross-sectional view showing the waste collection module 105 according to an embodiment of the present application, and the connection between the waste collection module 105 and the collection bucket 40 and the water collecting bucket 42. The cross-sectional view of the waste collection module 105 is taken along the cross-sectional line AA in Fig. 6. In Figure 2 In Fig. 7, it can be seen more clearly the internal structure of the cyclone collection bucket 10, the air inlet 20, the air outlet 22, the material outlet 28, the water collecting cover 26, and the water outlet 32. Figure 3

[0067] The material outlet 28 of the waste collection module 105 can be coupled with the collection bucket 40. In the present embodiment, the material outlet 28 is configured to be detachably coupled with the collection bucket 40. A sealing gasket 36 is provided between the material outlet 28 and the collection bucket 40 to avoid or reduce the chance of leakage of the solid pieces in the waste from the gap between the material outlet 28 and the collection bucket 40. In other embodiments, the sealing gasket 36 can be replaced by a protruding annular structure, and is coupled or integrally formed on the outer peripheral surface of the material outlet 28.

[0068] The collection bucket 40 can be, for example, composed of a bucket-shaped structure, or other geometric shapes. In other embodiments, the collection bucket 40 can be replaced by a bag-shaped structure or a box-shaped structure, but is not limited thereto.

[0069] The collection bucket 40 can be provided with a sensor 401, which can be used to sense the collection amount of the solid pieces in the waste. The sensor 401 can be, for example, a light sensor or a weight sensor, etc. In other embodiments, the collection bucket 40 can also be provided without the sensor 401. After the waste passes through the waste collection module 105, the solid pieces in the waste can be discharged from the material outlet 28 and collected in the collection bucket 40. In this way, when the collection bucket 40 is full, the user only needs to replace a new collection bucket 40 to continue the cleaning work, which not only shortens the time and frequency of cleaning the collection bucket 40, but also improves the use convenience of the waste collection module 105.

[0070] ​The drain outlet 32 ​​of the waste collection module 105 can be coupled to the water collection tank 42 via a drain channel 34. In this embodiment, the drain channel 34 is configured to be detachably coupled to the water collection tank 42. In other embodiments, the drain outlet 32 ​​of the waste collection module 105 may also be directly coupled to the water collection tank 42, omitting the drain channel 34. In other embodiments, the drain outlet 32 ​​is configured to be detachably coupled to the water collection tank 42. A sealing gasket 38 is provided between the drain outlet 32 ​​and the water collection tank 42 to prevent or reduce the chance of solid parts in the waste leaking from the gap between the drain outlet 32 ​​and the water collection tank 42. In other embodiments, the sealing gasket 38 may also be replaced by a protruding annular structure and coupled or integrally formed on a portion of the outer peripheral surface of the drain channel 34.

[0071] The water collection bucket 42 may be constructed, for example, of a bucket-shaped structure or other geometric shapes. In other embodiments, the water collection bucket 42 may also be replaced by a bag-shaped structure or a box-shaped structure, but is not limited thereto.

[0072] The water collection tank 42 may be equipped with a sensor 421 to sense the amount of water or liquid collected in the waste. The sensor 421 may be, for example, a float sensor, a water level sensor, or a weight sensor. In other embodiments, the water collection tank 42 may not be equipped with a sensor 421. When waste passes through the waste collection module 105, the water or liquid in the waste can be discharged through the drain outlet 32 ​​and collected in the water collection tank 42. Therefore, when the water collection tank 42 is full, the user only needs to replace it with a new one to continue cleaning, which not only reduces the frequency and time of cleaning the water collection tank 42 but also improves the ease of use of the waste collection module 105.

[0073] In addition, Figure 3 When combined with existing robotic vacuum cleaners, the structure can achieve automatic cleaning and dry / wet waste separation. It will be apparent to those skilled in the art that the dry / wet waste collection module 105 of this application can be combined with robotic vacuum cleaners, street cleaning vehicles, or many other entities not specifically mentioned in this application.

[0074] In summary, the waste collecting module and the sweeping robot of the present application use the cyclone power generated by the air suction source (i.e. air suction equipment) to suck in the waste, increase the cyclone intensity by the flow guide spiral part, and separate the water or liquid in the waste by centrifugal force to the water collecting chamber, the water or liquid in the water collecting chamber can be discharged through the water outlet, and the solid parts in the waste can be discharged along the flow guide spiral part to the discharge outlet, thereby completing the dry and wet separation process of the waste. Since the moisture in the air discharged by the waste collecting module is greatly reduced, the problem of corrosion of the air suction equipment due to moisture and reduction of service life can be solved. In addition, the sweeping robot of the present application can be configured with a water collecting bucket and a waste collecting bucket, which can relatively improve the waste collecting capacity, and by replacing the water collecting bucket or the waste collecting bucket, the cleaning frequency can be reduced. Furthermore, after dry and wet separation of the waste, the water collecting bucket and the waste collecting bucket can be more conveniently cleaned, the cleaning time is shortened, and the cleaning efficiency is greatly improved.
