Description

Technical Field

[0001] The present application relates to a waste collection module, and more particularly to a dry-wet separation waste collection module and a sweeping robot using the dry-wet separation waste collection module. Background Art

[0002] Current wet and dry vacuum cleaners can simultaneously suck together sewage, dust, paper scraps, glass and other solid waste on the ground into the dust collection bin when performing garbage cleaning operations. Since there is no need to avoid areas with sewage, the convenience of users when performing garbage cleaning operations can be improved.

[0003] However, because the above-mentioned wet and dry vacuum cleaner cannot separate sewage and solid waste, the sewage and solid waste are collected and mixed in the same dust collecting bucket. Utility Model Content

[0004] Based on the above design, the dust bin is easily filled up. Therefore, the user needs to clean the dust bin before continuing to use the wet and dry vacuum cleaner to clean garbage. Since the above cleaning times are frequent, there is still room for improvement in ease of use.

[0005] In addition, 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 poured into the sewage pipe before subsequent garbage disposal operations can be carried out. This process will increase the time for garbage disposal, and if the wet and dry vacuum cleaner is not designed with a water-proof and filtering structure, the suction equipment will be corroded by moisture and its service life will be reduced.

[0006] To solve the above problems, the purpose of the present application is to provide a waste collection module for dry-wet separation, comprising: a cyclone collection barrel having an axial line, a circular portion and a conical portion formed with a plurality of holes; an air inlet coupled to the circular portion and configured to inhale waste containing water and / or solid parts based on cyclonic power; an exhaust port arranged on the axial line and configured to couple with an air suction source to generate the cyclonic power; a discharge port formed at the end of the conical portion; a water collecting hood covering the outside of the conical portion and forming a water collecting chamber between the conical portion; and a drain port coupled to the water collecting chamber; wherein when the waste is driven by the cyclonic power through the conical portion, the water in the waste is centrifugally discharged to the water collecting chamber through the plurality of holes, and the water in the water collecting chamber is discharged from the drain port, and the solid parts in the waste are discharged from the discharge port.

[0007] In some embodiments, the invention further comprises a guide spiral portion distributed in the circular portion and the conical portion, wherein the guide spiral portion is configured to increase the cyclone intensity.

[0008] In some embodiments, the waste collection module is further coupled to a collection bucket, the waste collection module is coupled to the collection bucket through the discharge port, and the collection bucket is configured to collect solid objects in the waste.

[0009] In some embodiments, the collection bucket is further provided with a sensor for sensing the collected amount of solid pieces in the waste.

[0010] In some embodiments, a sealing gasket is provided between the discharge port and the collection bucket.

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

[0012] In some embodiments, the water collection bucket is further provided with a sensor for sensing the collected amount of water in the waste.

[0013] In some embodiments, the drain outlet and the water collecting bucket are connected via a drainage channel to transfer water in the waste.

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

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

[0016] In order to solve the above-mentioned problem, the purpose of the present application is to provide a sweeping robot, comprising a waste collection module for dry-wet separation as described above.

[0017] In summary, the waste collection module and the sweeping robot of the present application use the cyclonic power generated by the air extraction source (i.e., the suction device) to suck in the waste, increase the cyclonic strength by means of the guide spiral part, and use the centrifugal force to quickly separate the water or liquid in the waste into the water collection chamber, and the water or liquid in the water collection chamber can be discharged to the water collection bucket through the drain port, and the solid parts in the waste can be discharged to the collection bucket through the discharge port along the guide spiral part, thereby completing the process of dry and wet separation of the waste. Since the moisture in the air discharged by the waste collection module is greatly reduced, the problem of reduced service life of the suction device due to moisture corrosion can be solved. In addition, the sweeping robot of the present application can be equipped with a water collection bucket and a collection bucket, which relatively increases the collection capacity of the waste, and can reduce the number of cleaning times by individually replacing the water collection bucket or the collection bucket. Furthermore, after the dry and wet separation of the waste, the water collection bucket and the collection bucket can be more convenient to clean, shortening the cleaning time and greatly improving the cleaning efficiency.

[0044] 105 Waste Collection Module DETAILED DESCRIPTION

[0045] The "water" in the waste of the present application embodiment may refer to liquid, and is not limited to the waste including clean water or sewage. Therefore, although the following description uses "water" as an example, it is not limited to this.

[0046] Please refer to Figure 1A , is a schematic diagram showing the structure of the waste collection module 100 of an embodiment of the present application. The waste collection module 100 may include: a cyclone collection barrel 10, an air inlet 20, an exhaust port 22, a discharge port 28, a water collection cover 26 and a drain port 32. In the present embodiment, the structural features of the cyclone collection barrel 10, the air inlet 20, the exhaust port 22, the discharge port 28, the water collection cover 26 and the drain port 32 may be achieved by using molds and injection molding technology to achieve the desired shape, but are not limited to this. In other embodiments, other processing methods such as granulation, extrusion molding, and stamping may also be used to achieve the desired shape. The above-mentioned components may be coupled to each other by an integrated molding method to improve the convenience and efficiency of manufacturing, or other fixing means such as assembly, snap-fit, bonding and / or locking may be used to couple the components to each other to improve the flexibility of component maintenance and the convenience of component replacement.

[0047] The cyclone collection barrel 10 may have an axis 11, a circular portion 12 and a conical portion 14 formed with a plurality of holes 141. The cyclone collection barrel 10 may be roughly divided into an upper section (not shown), a middle section (not shown) and a lower section (not shown) along the axis 11.

[0048] The axis line 11 is substantially located at the center of the circular portion 12. The circular portion 12 is located at the upper section of the cyclone collecting barrel 10. The appearance of the circular portion 12 is substantially cylindrical.

[0049] The conical portion 14 has a conical structure that gradually narrows from wide to narrow along the axis 11 toward the lower section of the cyclone collection barrel 10. In the local structure of the conical portion 14 covered by the water collecting 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 conical portion 14, but is not limited thereto. In other embodiments, the inner diameter of the circular portion 12 can also be smaller than the inner diameter of the conical portion 14.

[0050] One end of the air inlet 20 can be coupled to the circular portion 12. The air inlet 20 is generally arranged in the tangential direction of the circular portion 12. The appearance of the air inlet 20 is generally tubular. The other end of the air inlet 20 can be designed to have structural features for engaging other components (for example, internal threads, external threads, snaps, plugs, etc.). The air inlet 20 is configured to inhale waste containing water or other liquids (not shown in the figure), waste containing solid parts (for example, powder, leaves, plastic, dust, sand, hair, paper scraps, glass and / or metal, etc.), or waste containing both water and solid parts based on cyclonic power.

[0051] The exhaust port 22 is disposed on the axis line 11. The appearance of the exhaust port 22 is generally tubular. One end of the exhaust port 22 can be coupled to the circular portion 12 and penetrate into the interior of the cyclone collection barrel 10. The other end of the exhaust port 22 can protrude from the top surface of the circular portion 12, and can be designed to have structural features for engaging other components (e.g., internal threads, external threads, snaps, plugs, etc.). The exhaust port 22 is configured to be coupled to an air extraction source (e.g., a suction device, a motor, etc.) to generate cyclonic power.

[0052] The operation principle of the waste collection module 100 is described below.

[0053] When the air suction source starts to operate, cyclonic power can be generated, so that air can be sucked from 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, a cyclone can be generated inside the waste collection module 100 and discharged from the exhaust port 22.

[0054] When the waste is driven by the cyclonic power and sucked from the air inlet 20, the waste may rotate downward along the cyclonic direction. The waste may contain water and / or solid objects.

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

[0056] The solid pieces in the waste rotate in a centrifugal manner toward the lower section of the waste collection module 100 (for example, the direction of the discharge port 28), and most of the solid pieces are blocked by the inner wall of the conical portion 14 because they cannot pass through the hole 141 on the conical portion 14. The waste blocked by the inner wall of the conical portion 14 can continue to rotate downward along the cyclonic direction. Finally, the solid pieces in the waste are discharged through the discharge port 28, thereby completing the process of "dry separation" of the waste. In this way, the waste collection module 100 that inhales the waste can effectively perform "wet separation" and "dry separation" to significantly reduce the moisture in the air discharged through the exhaust port 22, thereby improving the problem of reduced service life of the existing suction equipment due to moisture corrosion.

[0057] Please refer to Figure 1B , is a schematic diagram showing the structure of a waste collection module 105 according to another embodiment of the present application. Figure 1B Examples and Figure 1A The difference of the embodiment is that: Figure 1B The waste collection module 105 further includes a guide spiral portion 13. In the present embodiment, the partial structure of the guide spiral portion 13 can be seen from the upper surface of the circular portion 12. More specifically, at the coupling portion between the air inlet 20 and the circular portion 12, a spiral structure (i.e., a partial structure of the guide spiral portion 13) is formed on the upper surface of the circular portion 12, which is designed to rotate and extend downward along the axis 11 toward the discharge port 28. The aforementioned spiral structure design allows the air sucked in by the air inlet 20 to be quickly and directly guided downward, and can reduce the turbulence phenomenon between the coupling portion of the air inlet 20 and the circular portion 12, thereby improving the cyclone efficiency inside the cyclone collection barrel 10.

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

[0059] In the present embodiment, the spiral structure in the guide spiral portion 13 is distributed in the circular portion 12 and the conical portion 14 in an equidistant manner. In other embodiments, the spiral structure in the guide spiral portion 13 is distributed in the circular portion 12 and the conical portion 14 in a non-equidistant manner. For example, the aforementioned spiral structure can be distributed in the upper section of the cyclone collecting barrel 10 in a first grid distance manner, and in the middle and lower sections of the cyclone collecting barrel 10 in a second grid distance manner that is smaller than the first grid distance, but not limited to this. By changing the spacing distance of the spiral structure in the guide spiral portion 13, the cyclone efficiency inside the cyclone collecting barrel 10 can be adjusted accordingly. In other words, the guide spiral portion 13 can be configured to increase the cyclone intensity. In addition, Figure 1B The rest of the structure is Figure 1A The embodiments are the same or similar and will not be described in detail here.

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

[0061] When the air extraction source starts to operate, cyclonic power can be generated, so that air can be sucked in from the air inlet 20 of the waste collection module 105 to form an airflow. When the airflow passes through the guide spiral portion 13, a cyclone can be generated inside the waste collection module 105 and discharged from the exhaust port 22.

[0062] When the waste is driven by the aforementioned cyclonic power and sucked from the air inlet 20, the waste may rotate downward along the spiral direction of the guide spiral portion 13. The aforementioned waste may include water and / or solid objects.

[0063] When the waste passes through the conical portion 14, the water in the waste is discharged into the water collection chamber 30 in a centrifugal manner through the multiple holes 141 on the conical portion 14, and the water discharged into the water collection chamber 30 through the holes 141 is collected in the water collection chamber 30 and then discharged through the drain port 32, thereby completing the "wet separation" process of the waste.

[0064] The solid pieces in the waste rotate in a centrifugal manner toward the lower section of the waste collection module 105 (for example, the direction of the discharge port 28), and most of the solid pieces are blocked by the inner wall of the conical portion 14 because they cannot pass through the hole 141 on the conical portion 14. The waste blocked by the inner wall of the conical portion 14 can continue to rotate downward along the guide spiral portion 13. Finally, the solid pieces in the waste are discharged through the discharge port 28, thereby completing the process of "dry separation" of the waste. In this way, the waste collection module 105 that inhales the waste can effectively perform "wet separation" and "dry separation" to significantly reduce the moisture in the air discharged through the exhaust port 22, thereby improving the problem of reduced service life of the existing suction equipment due to moisture corrosion.

[0065] Please refer to Figure 2, is a schematic diagram showing a top view of a waste collection module 105 according to another embodiment of the present application. Figure 2 In the figure, it can be seen more clearly that the air inlet 20 is roughly arranged in the tangent direction of the circular portion 12. The appearance of the water collecting cover 26 is roughly cylindrical, but not limited to this. The drain port 32 is arranged on one side of the water collecting cover 26. In the present embodiment, the number of the air inlet 20 and the drain port 32 are 1 respectively. In other embodiments, the number of the air inlet 20 and the drain port 32 can also be increased according to design requirements. In other embodiments, the drain port 32 can also be arranged in the tangent direction of the water collecting cover 26, that is, the positions of the air inlet 20 and the drain port 32 can be adjusted according to design requirements.

[0066] Please refer to Figure 3 , is a schematic cross-sectional structural diagram showing the waste collection module 105 of the embodiment of the present application being connected to the waste collection bucket 40 and the water collection bucket 42. Figure 2 The section line AA is taken. Figure 3 In the figure, the internal structures of the cyclone collection barrel 10, the air inlet 20, the exhaust port 22, the discharge port 28, the water collection cover 26 and the water discharge port 32 can be seen more clearly.

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

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

[0069] The collection bucket 40 may be provided with a sensor 401, which can be used to sense the amount of solid pieces collected in the waste. The sensor 401 may be, for example, a light sensor or a weight sensor. In other embodiments, the collection bucket 40 may not be provided with the sensor 401. After the waste passes through the waste collection module 105, the solid pieces in the waste can be discharged from the discharge port 28 and collected in the collection bucket 40. Thus, when the collection bucket 40 is full, the user only needs to replace the new collection bucket 40 to continue the cleaning operation, which can not only shorten the number and time of cleaning the collection bucket 40, but also improve the convenience of using the waste collection module 105.

[0070] The drain port 32 of the waste collection module 105 can be coupled to the water collection bucket 42 through the drain channel 34. In the present embodiment, the drain channel 34 is configured to be detachably coupled to the water collection bucket 42. In other embodiments, the drain port 32 of the waste collection module 105 can also be directly coupled to the water collection bucket 42, and the drain channel 34 is omitted. In other embodiments, the drain port 32 is configured to be detachably coupled to the water collection bucket 42. A sealing gasket 38 is provided between the drain port 32 and the water collection bucket 42 to avoid or reduce the chance of solid parts in the waste leaking from the gap between the drain port 32 and the water collection bucket 42. In other embodiments, the sealing gasket 38 can also be replaced by a protruding annular structure, and coupled or integrally formed on the local outer peripheral surface of the drain channel 34.

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

[0072] The water collecting bucket 42 may be provided with a sensor 421, which can be used 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 collecting bucket 42 may not be provided with the sensor 421. After the waste passes through the waste collecting module 105, the water or liquid in the waste can be discharged from the drain port 32 and collected in the water collecting bucket 42. Thus, when the water collecting bucket 42 is full, the user only needs to replace the new water collecting bucket 42 to continue the cleaning operation, which can not only shorten the number and time of cleaning the water collecting bucket 42, but also improve the convenience of using the waste collecting module 105.

[0073] In addition, Figure 3 After the structure is combined with the current sweeping robot, the functions of automatic cleaning and dry-wet separation of waste can be realized. For those familiar with the technology, it is obvious that the dry-wet separation waste collection module 105 of the present application can be combined with a sweeping robot, a street sweeping cleaning vehicle or many other mechanisms not specifically mentioned in the present application.

[0074] In summary, the waste collection module and the sweeping robot of the present application, after using the cyclonic power generated by the air extraction source (i.e., the suction device) to suck in the waste, increase the cyclonic strength by means of the guide spiral part, and use the centrifugal force to quickly separate the water or liquid in the waste into the water collection chamber, and the water or liquid in the water collection chamber can be discharged through the drain port, and the solid parts in the waste can be discharged through the discharge port along the guide spiral part, thereby completing the process of dry and wet separation of the waste. Since the moisture in the air discharged by the waste collection module is greatly reduced, the problem of reduced service life of the suction device due to moisture corrosion can be solved. In addition, the sweeping robot of the present application can be equipped with a water collection bucket and a collection bucket, which relatively increases the collection capacity of the waste, and can reduce the number of cleaning times by individually replacing the water collection bucket or the collection bucket. Furthermore, after the dry and wet separation of the waste, the water collection bucket and the collection bucket can be more convenient to clean, shortening the cleaning time and greatly improving the cleaning efficiency.
