Description

Technical Field

[0001] This utility model relates to the field of dustbin cleaning technology for sweeping machines, specifically to a rear-removable dustbin for sweeping machines and a sweeping robot. Background Technology

[0002] A robotic vacuum cleaner consists of a main body and a rear-removable dustbin (a dustbin that can be removed from the rear of the main body). The dustbin is installed inside the main body. The main body's fan rotates at high speed, creating negative pressure, which in turn generates a suction airflow. This airflow draws debris from the external environment into the dustbin. Simultaneously, the dustbin's filtration system filters out debris (such as dust, hair, or shredded paper), preventing it from being carried by the airflow to the fan.

[0003] However, after a period of use, the dustbin of a rear-removable sweeper can become clogged with debris, reducing its filtration efficiency. In this case, the user needs to remove the dustbin first, then remove the filter, thoroughly clean the filter, and finally reinstall it into the dustbin. Clearly, the current method of cleaning the filter is cumbersome, labor-intensive, and inconvenient. Utility Model Content

[0004] The purpose of this utility model is to solve the following technical problem: the cleaning method of the filter mechanism of the dust box of the rear-removable sweeper is very cumbersome and labor-intensive, which is very inconvenient.

[0005] To achieve the above objectives, this utility model provides a rear-removable dustbin for a sweeper, comprising: a dustbin body, the interior of which has a first chamber for containing waste; a suction port and a blowing port on the front wall of the dustbin body facing the sweeper body, the suction port communicating with the first chamber and used for absorbing waste, and the suction port and blowing port being selectively openable or closed; a dust collection port on the rear wall of the dustbin body facing the sweeper body, the dust collection port communicating with the first chamber and being able to communicate with a dust collection device, the dust collection port being selectively openable or closed; the suction port and dust collection port being relatively distributed along the length of the dustbin body; and a filter mechanism, the filter mechanism being installed on the top of the dustbin body, the filter mechanism having a second chamber and a first filter element capable of filtering waste, the second chamber communicating with the first chamber through the first filter element, and the second chamber communicating with both the blowing port and the working chamber of the sweeper body's fan.

[0006] In some embodiments, the filter mechanism has a dust inlet, the dust inlet and the dust outlet are directly opposite each other in the longitudinal direction of the dust box body, and the dust outlet communicates with the second chamber through the dust inlet.

[0007] In some embodiments, a second filter capable of filtering debris is provided at the dust inlet.

[0008] In some embodiments, the second filter element is a filter screen.

[0009] In some embodiments, the filtration mechanism further includes a mounting box, which is mounted on the top of the dust box body. The bottom wall of the mounting box has a filter opening that exposes the first filter element. The mounting box has a second chamber and a dust blowing inlet on its side wall.

[0010] In some embodiments, the first filter element extends downwardly from its side away from the fan to its side facing the fan.

[0011] In some embodiments, the suction port is angled and faces the first filter.

[0012] In some embodiments, the suction port is provided with a first opening and closing adjustment mechanism that allows the suction port to open or close; and / or, the blowing port is provided with a second opening and closing adjustment mechanism that allows the blowing port to open or close.

[0013] In some embodiments, a sealing plate is provided at the dust collection port to allow the dust collection port to be opened or closed.

[0014] Another aspect of this utility model provides a sweeping robot, which includes a sweeping robot body and a rear-removable sweeping robot dust box as described in the above embodiment. The rear-removable sweeping robot dust box is detachably installed on the sweeping robot body, and the fan working chamber of the sweeping robot body is connected to the second chamber.

[0015] The technical solution of this utility model has the following beneficial effects: The dust collection port of the dust box body is connected to the dust collection device. The dust collection port is set to open, the suction port can be set to open or closed, and the blowing port is set to open. This allows the dust collection device to generate a second airflow when sucking up the garbage in the first chamber. The second airflow can flow sequentially along the path of the blowing port, the second chamber, the first filter element, the first chamber, the dust collection port, and the dust collection device. This second airflow can also impact the garbage clogging the first filter element and blow the garbage clogging the first filter element into the first chamber, thereby cleaning the filtration mechanism. Therefore, the dust box of the rear-removable sweeper of this utility model can achieve self-cleaning of the filtration mechanism. The cleaning method is simple and requires little manual labor, making it very convenient. Attached Figure Description

[0018] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. It should be understood that the specific embodiments described herein are intended only to explain this utility model and not to limit it. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this utility model by illustrating examples of it.

[0019] like Figures 1 to 4As shown, this utility model provides a rear-removable dustbin for a sweeper, which includes a dustbin body 1 and a filter mechanism 2. The dustbin body 1 has a first chamber 11 for containing waste. The front wall of the dustbin body 1 facing the sweeper body has a suction port 12 and a blowing port 13. The suction port 12 communicates with the first chamber 11 and is used to absorb waste; the suction port 12 and the blowing port 13 are configured to be selectively opened or closed. The rear wall of the dustbin body 1 facing the sweeper body has a dust collection port 14, which communicates with the first chamber 11 and can communicate with a dust collection device. The dust collection port 14 is configured to be selectively opened or closed. The suction port 12 and the dust collection port 14 are distributed opposite each other along the length L of the dustbin body 1. The filter mechanism 2 is installed on the top of the dust box body 1. The filter mechanism 2 has a second chamber 21 and a first filter element 22 that can filter garbage. The second chamber 21 is connected to the first chamber 11 through the first filter element 22. The second chamber 21 is connected to the dust blowing port 13 and the fan working chamber 3 of the sweeper body.

[0020] Specifically, after the dustbin body 1 is installed on the sweeper body, the second chamber 21 is connected to the blower working chamber 3 (the chamber where the blower works) of the sweeper body. When it is necessary to suck up garbage from the environment, the suction port 12 is set to open, the dust blowing port 13 is set to close, and the dust collection port 14 is set to close. At the same time, the blower of the sweeper body operates, which generates negative pressure in the blower working chamber 3 of the sweeper body. Based on the negative pressure in the blower working chamber 3, a first airflow 4 is formed that can flow sequentially along the path of the suction port 12, the first chamber 11, the first filter 22, the second chamber 21, and the blower working chamber 3. Garbage near the suction port 12 can be sucked into the first chamber 11 through the suction port 12. The first chamber 11 can hold garbage, and the first filter 22 can filter the first airflow 4 to prevent garbage from entering the blower working chamber 3 with the first airflow 4. However, after a period of use, some of the filter holes of the first filter 22 will be blocked by garbage.

[0021] When a certain amount of waste is stored in the first chamber 11, a dust collection device is used to suck up the waste in the first chamber 11, emptying it. When cleaning the waste in the first chamber 11, the dust collection port 14 of the dust box body 1 is connected to the dust collection device. The dust collection port 14 is set to open, the suction port 12 can be set to open or closed, and the blowing port 13 is set to open. At the same time, the dust collection device operates, sucking up the waste in the first chamber 11 through the dust collection port 14. When the dust collection device sucks up the waste, a second airflow 5 is formed that flows sequentially along the path of the blowing port 13, the second chamber 21, the first filter element 22, the first chamber 11, the dust collection port 14, and the dust collection device. This second airflow 5 can impact the waste clogged in the first filter element 22 and blow the waste clogged in the first filter element 22 into the first chamber 11, thereby enabling the filter mechanism 2 to achieve self-cleaning. In addition, when the suction port 12 is set to open, a third airflow 6 is formed that can flow sequentially along the path of the suction port 12, the first chamber 11, the dust collection port 14 and the dust collection device. The third airflow 6 can impact the side of the first filter 22 facing the first chamber 11 and blow the garbage attached to the surface into the first chamber 11.

[0022] In summary, in this embodiment, the dust collection port 14 of the dust box body 1 is connected to the dust collection device. The dust collection port 14 is set to be open, the suction port 12 can be set to be open or closed, and the blowing port 13 is set to be open. This allows the dust collection device to generate a second airflow 5 when sucking up the garbage in the first chamber 11. The second airflow 5 can flow sequentially along the path of the blowing port 13, the second chamber 21, the first filter element 22, the first chamber 11, the dust collection port 14, and the dust collection device. Furthermore, the second airflow 5 can impact the garbage clogged in the first filter element 22 and blow the garbage clogged in the first filter element 22 into the first chamber 11, thereby cleaning the filter mechanism 2. Therefore, the rear-removable dust box of this utility model can achieve self-cleaning of the filter mechanism 2. The cleaning method is simple and requires little manual labor, making it very convenient.

[0023] It should be noted that the first filter element 22 can be any form that meets the requirements of this utility model, and this utility model is not limited thereto. For example, the first filter element 22 can be a HEPA filter or a filter screen, etc.

[0024] like Figures 1 to 4 As shown, in some embodiments of the present invention, the filter mechanism 2 has a dust inlet 23, the dust outlet 13 and the dust inlet 23 are directly opposite each other in the length direction L of the dust box body 1, and the dust outlet 13 is connected to the second chamber 21 through the dust inlet 23.

[0025] Specifically, the dust outlet 13, the dust inlet 23, and the second chamber 21 form a straight path. When the dust collection device performs suction, the second airflow 5 can directly enter the second chamber 21 along this straight path, avoiding energy loss due to changes in the flow direction of the second airflow 5. This allows the second airflow 5 to maintain a large impact force, facilitating the blowing out of the debris clogging the first filter element 22, thereby improving the cleaning effect of the filter mechanism 2.

[0026] In some embodiments, the blowout 13 is located above the suction port 12.

[0027] like Figures 1 to 4 As shown, in some embodiments of this utility model, a second filter element 24 capable of filtering garbage is provided at the dust inlet 23 to prevent garbage from the external environment from entering the second chamber 21 from the dust outlet 13 and the dust inlet 23.

[0028] In some embodiments of this invention, the second filter element 24 is a filter screen. Of course, the second filter element 24 can also be other components, such as filter cloth or filter, etc., and this invention does not impose any limitations.

[0029] like Figures 1 to 4 As shown, in some embodiments of this utility model, the filter mechanism 2 further includes a mounting box 25, which is mounted on the top of the dust box body 1. The bottom wall of the mounting box 25 is provided with a filter opening that exposes the first filter element 22. The mounting box 25 has a second chamber 21, and the side wall of the mounting box 25 is provided with a dust blowing inlet 23. By providing the mounting box 25, it is convenient to install the first filter element 22 and to form a relatively independent second chamber 21.

[0030] In some embodiments, the filter mechanism 2 further includes a partition 26. The side of the mounting box 25 facing the dust outlet 13 is sealed to the box wall of the dust box body 1 facing the front of the sweeper body via the partition 26. The partition 26 is disposed below the dust inlet 23 and the dust outlet 13. Of course, the partition 26 is also disposed below the second opening and closing adjustment mechanism 16 and the second filter element 24. The partition 26 isolates both the dust inlet 23 and the dust outlet 13 from the first chamber 11, preventing a small portion of the second airflow 5 from flowing directly downwards from the dust outlet 13 into the first chamber 11, and also preventing the third airflow 6 and the second airflow 5 from interfering with each other, thus ensuring the airflow intensity of the second airflow 5.

[0031] like Figures 1 to 4 As shown, in some embodiments of this utility model, the first filter element 22 extends downward at an angle from its side facing away from the fan to its side facing the fan. Wherein, compared to a flat arrangement, an angled arrangement of the first filter element 22 results in a larger filtration surface, thereby improving the filtration effect.

[0032] In some embodiments of this invention, the suction port 12 is inclined and faces the first filter element 22. When the third airflow 6 is formed, the third airflow 6 can blow towards the side of the first filter element 22 facing the first chamber 11, thereby improving the self-cleaning effect of the first filter element 22.

[0033] like Figures 1 to 4 As shown, in some embodiments of this utility model, a first opening and closing adjustment mechanism 15 is provided at the dust suction port 12 to allow the dust suction port 12 to be opened or closed.

[0034] Specifically, when it is necessary to suck up debris from the external environment, the first opening and closing adjustment mechanism 15 opens the suction port 12. When it is necessary to empty the debris from the first chamber 11, the first opening and closing adjustment mechanism 15 can open the suction port 12, forming a third airflow 6. When it is necessary to improve the cleaning ability of the second airflow 5, the first opening and closing adjustment mechanism 15 can close the suction port 12, so that only the second airflow 5 is present in the dust box body 1, but the intensity of the second airflow 5 is higher, and the cleaning ability is stronger. Of course, by setting the first opening and closing adjustment mechanism 15, the self-cleaning ability of the filter mechanism 2 can also be adjusted.

[0035] like Figures 1 to 4 As shown, in some embodiments of this utility model, a second opening and closing adjustment mechanism 16 is provided at the dust blowing port 13 to allow the dust blowing port 13 to open or close.

[0036] Specifically, when vacuuming is required, the second opening and closing adjustment mechanism 16 closes the dust outlet 13. When cleaning the filter unit 2 is required, the second opening and closing adjustment mechanism 16 opens the dust outlet 13.

[0037] It should be noted that the first opening and closing adjustment mechanism 15 and the second opening and closing adjustment mechanism 16 can be any structural form that can achieve the above-mentioned technical effects, and this utility model does not impose any restrictions.

[0038] For example, in some embodiments, the first opening / closing adjustment mechanism 15 and the second opening / closing adjustment mechanism 16 include a common magnetic suction assembly and a sealing plate. The top of the sealing plate is rotatably disposed on the dustbin body 1, a part of the magnetic suction assembly is disposed on the bottom of the sealing plate, and the other part of the magnetic suction assembly is disposed on the dustbin body 1. The controller of the sweeper body can control the battery of the sweeper body to supply power to the magnetic suction assembly. When the battery of the sweeper body supplies power to the magnetic suction assembly, a magnetic force is generated between one part of the magnetic suction assembly and the other part of it, and they are magnetically connected to each other. At this time, the sealing plate closes the suction port 12 through the magnetic suction assembly. When the battery of the sweeper body is de-energized, there is no magnetic connection between one part of the magnetic suction assembly and the other part of it. When the dust collection device performs suction, a negative pressure is generated in the first chamber 11. The sealing plate can rotate based on this negative pressure, thereby opening the suction port 12.

[0039] For example, in some embodiments, such as Figure 5 As shown, the first opening and closing adjustment mechanism 15 and the second opening and closing adjustment mechanism 16 include a drive motor 151 and a sealing plate 152. A rotating shaft 153 is fixedly installed on the top of the sealing plate 152. The top of the sealing plate 152 is rotatably connected to the dust box body 1 through the rotating shaft 153. The drive motor 151 is installed on the dust box body 1. The controller of the sweeper body can control the battery of the sweeper body to supply power to the drive motor 151. The drive motor 151 can drive the rotating shaft 153 to rotate, and the rotating shaft 153 drives the sealing plate 152 to rotate, thereby opening the suction port 12. The drive motor 151 drives the rotating shaft 153 to rotate in the opposite direction, and the sealing plate 152 can close the suction port 12. The drive motor 151 can also provide a certain force to position the sealing plate 152 in the position of closing the suction port 12.

[0040] In some embodiments of this utility model, a sealing plate 17 is provided at the dust collection port 14 to allow the dust collection port 14 to be opened or closed.

[0041] Specifically, when it is necessary to suck up garbage from the external environment, the sealing plate 17 closes the dust collection port 14. When it is necessary to empty the garbage in the first chamber 11, the sealing plate 17 opens, allowing the dust collection port 14 to connect with the dust collection device.

[0042] It should be noted that the sealing plate 17 can open or close the dust collection port 14 in any form that meets the requirements of this utility model, and this utility model does not impose any restrictions.

[0043] For example, in some embodiments, the top of the sealing plate 17 is rotatably connected to the dust box body 1, and a limiting block is provided at the dust collection port 14. The limiting block is located between the first chamber 11 and the sealing plate 17, and the limiting block can prevent the sealing plate 17 from rotating toward the first chamber 11. When vacuuming, a negative pressure is formed in the first chamber 11, but the limiting block can prevent the sealing plate 17 from rotating toward the first chamber 11, so that the sealing plate 17 is kept in the position of closing the dust collection port 14. When the dust collection device sucks the garbage in the first chamber 11, based on the suction of the dust collection device, the sealing plate 17 rotates away from the first chamber 11, so that the dust collection port 14 opens.

[0044] For example, referring to the arrangement of the first opening and closing adjustment mechanism 15 and the second opening and closing adjustment mechanism 16, the top of the sealing plate 17 is also rotatably connected to the dust box body 1 via a rotating shaft 153. Another drive motor 151 is installed on the dust box body 1. The controller of the sweeper body can control the battery of the sweeper body to supply power to the drive motor 151. The drive motor 151 can drive the rotating shaft 153 to rotate, and the rotating shaft 153 drives the sealing plate 17 to rotate, thereby opening the dust collection port 14. The drive motor 151 drives the rotating shaft 153 to rotate in the opposite direction, and the sealing plate 17 can close the dust collection port 14. The drive motor 151 can also provide a certain force to position the sealing plate 17 in the position of closing the dust collection port 14.

[0045] Another aspect of this utility model provides a sweeping robot, which includes a sweeping robot body and a rear-removable sweeping robot dust box as described in the above embodiment. The rear-removable sweeping robot dust box is detachably installed on the sweeping robot body, and the fan working chamber of the sweeping robot body is connected to the second chamber 21.

[0046] Specifically, the sweeping robot uses the rear-removable dustbin of the above embodiment, which can also achieve the above technical effect.

[0047] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The above examples are only for the purpose of helping to understand the method and core ideas of this utility model. The above are only preferred embodiments of this utility model. It should be noted that due to the limitations of textual expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this utility model, and can also combine the above technical features in an appropriate manner. These improvements, modifications, changes, or combinations, or the direct application of the concept and technical solution of this utility model to other occasions without modification, should all be considered within the protection scope of this utility model.
