[0035] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0036] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, and other quantifiers are similar.
[0037] It should be understood that although the terms "first," "second," "third," etc., may be used in the embodiments of this application, these descriptions should not be limited to these terms. These terms are only used to distinguish the described objects. For example, "first" may also be referred to as "second," and similarly, "second" may also be referred to as "first," without departing from the scope of the embodiments of this application. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0038] It should be understood that the term "and / or" used in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0040] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or device that includes that element.
[0041] In related technologies, cleaning equipment is equipped with a dust box. When the equipment performs a cleaning task, an external power source creates negative pressure inside the dust box, drawing debris into it. During this process, an airflow path is formed from the dust inlet to the external power source. A filter assembly is installed in this airflow path to filter dust and prevent it from entering and damaging the power source. However, after prolonged use, the filter assembly becomes covered in dust, affecting the airflow path and reducing cleaning efficiency.
[0042] Therefore, this application provides a dust box, including: a housing, including a dust inlet and a first opening; a filter assembly disposed at the first opening for filtering dust in the airflow direction from the dust inlet to the first opening; and a vibration assembly disposed near the filter assembly for providing vibration force to the filter assembly to accelerate the shedding of dust from the filter assembly.
[0043] The dust box proposed in this application has a vibration component installed near the filter component. The vibration of the vibration component can shake off at least part of the dust accumulated on the filter component into the dust box, thereby ensuring the service life of the filter component. At the same time, it ensures the smooth flow of air when the subsequent airflow passes through the filter component, and also improves the dust collection efficiency of the dust box.
[0044] The optional embodiments of this application are described in detail below with reference to the accompanying drawings.
[0045] like Figure 1 As shown, this application embodiment provides a dust box 10, which includes a housing 11, a filter assembly 12, and a vibration assembly 13. The housing 11 includes a dust inlet 111 and a first opening 112. The filter assembly 12 is disposed in the first opening 112 and is used to filter dust in the airflow direction from the dust inlet 111 to the first opening 112. The vibration assembly 13 is disposed near the filter assembly 12 and is used to provide vibration force to the filter assembly 12 to accelerate the shedding of dust on the filter assembly 12.
[0046] The dust box 10 is used to collect waste when the cleaning equipment performs cleaning tasks. An external power source provides suction through the first opening 112, causing airflow from the dust inlet 111 to the first opening 112. The dust box 10 forms a negative pressure under the suction of the external power source, and waste enters the dust box 10 from the dust inlet 111. Simultaneously, some dust particles accumulate on the filter assembly 12. When the cleaning equipment arrives at the base station to perform a dust collection task, the waste in the dust box is suctioned by the base station's power source and enters the base station's dust bin or dust bag from the dust outlet 113. During this process, the vibration assembly 13 vibrates. Because the vibration assembly 13 is positioned close to the filter assembly 12, its vibration causes the filter assembly 12 to vibrate, causing the accumulated dust on the filter assembly 12 to fall off and be discharged from the dust box by the base station's suction. This ensures the cleanliness of the filter assembly, extends its service life, ensures smooth airflow in the filter assembly during the next cleaning task, increases airflow, and improves the efficiency of negative pressure formation within the dust box, thereby improving the cleaning efficiency of the cleaning equipment.
[0047] In some embodiments, the vibration assembly 13 includes one or more vibration units. For example, there may be one, two, three, or even more vibration units; the number is not limited thereto. Different numbers of vibration units are provided depending on the location of the dustbin to provide a reasonable vibration force. Optionally, the vibration unit may be a linear motor, an ultrasonic motor, or a combination of both. Exemplarily, the vibration unit may be one or more linear motors, one or more ultrasonic motors, or a combination of one or more linear motors and ultrasonic motors. The linear motor, for example, is a button-type linear motor, which is small in size and easy to install in narrow grooves or crevices. Because linear motors have low vibration force, multiple linear motors can be provided to enhance the vibration intensity.
[0048] In some embodiments, when there are multiple vibration units, the multiple vibration units are evenly distributed near the filter assembly 12. Through a roughly uniformly distributed arrangement, dust at various locations on the filter assembly 12 can be shaken off cleanly. The multiple vibration units being evenly distributed near the filter assembly 12 can be evenly distributed along one side of the filter assembly 12, or evenly distributed on both sides, three sides, or all around, without limitation.
[0049] In some embodiments, the vibration assembly 13 further includes an electrical connection terminal, which is electrically connected to one or more vibration units for supplying power to the vibration units. Multiple vibration units can be connected in parallel or series using a single electrical connection terminal, or separate electrical connection terminals can be provided for each vibration unit; there is no limitation on this. Optionally, the electrical connection terminal can be a contact-type electrical connection terminal or a wire-type electrical connection terminal. When a contact-type electrical connection terminal is used, when the dust box is assembled onto the cleaning equipment, the contact-type electrical connection terminal contacts the corresponding power supply position on the cleaning equipment, thereby enabling the vibration unit to conduct electricity and subsequently perform vibration tasks according to the working state or control commands of the cleaning equipment. This contact-type electrical connection terminal is convenient to use, requires no additional leads, and enhances the neatness of the vibration assembly. Of course, a wire-type electrical connection terminal can also be used, which provides more options for power supply positions.
[0050] In some embodiments, such as Figure 2As shown, the housing 10 also includes multiple reinforcing ribs 114 to enhance its robustness. The multiple reinforcing ribs 114 are located on the side of the housing 10 adjacent to the surface to be cleaned; however, they can also be located at other positions on the housing 10. Multiple groove structures are formed between the multiple reinforcing ribs 114, and the vibration assembly 13 can be disposed within the groove structures between adjacent reinforcing ribs. This arrangement fully utilizes the unused space between the dust box reinforcing ribs without adding extra structural or manufacturing costs. Furthermore, because this location is adjacent to the filter assembly 12, it can economically and efficiently provide vibration force to the filter assembly 12. Understandably, a fixing structure can be provided at a corresponding position to fix the vibration assembly 13; this is not limited.
[0051] In some embodiments, such as Figure 2 As shown, the filter assembly 12 includes a filter frame 121 and a filter screen 122, with the filter screen 122 disposed on the filter frame 121. Optionally, the filter frame 121 includes an outer frame with a rectangular, elliptical, or other shaped structure, and a rib disposed within the outer frame. Optionally, the filter screen 122 is detachably disposed on the filter frame 121, forming a detachable structure for easy replacement of the filter screen 122. A sealing strip can be provided between the filter assembly 12 and the first opening 112 for sealing. In some embodiments, the filter screen 122 is HEPA paper or multi-layer perforated paper.
[0052] In other embodiments, such as Figure 3 As shown, the housing 11 also includes at least one groove 115, which is disposed on the side of the housing 11 adjacent to and / or away from the surface to be cleaned, and the filter assembly 13 is disposed within the groove 115. It is understood that the groove 115 can be disposed anywhere around the filter frame 121, and therefore, the filter assembly 13 can be disposed anywhere around the filter frame 121 without limitation.
[0053] Optionally, the vibration assembly 13 may be fitted at any location on the outer periphery of the filter frame 121, such as the side, to provide a sufficiently strong vibration force.
[0054] In other embodiments, such as Figure 4As shown, the housing 10 also includes a second opening 116, which forms a unidirectional air outlet. During dust collection, as the vibration component 13 vibrates, the filter component 12 vibrates and shakes off the dust. Simultaneously, an external power source 20 connects to the second opening 116 through the air outlet 21, blowing air into the housing 11 from the second opening 116 to accelerate the rate at which dust falls off and is discharged from the filter component 12. The second opening 116 is unidirectional; during dust collection, it opens when airflow blows from outside the dust box towards the inside. During cleaning and waste collection, the second opening 116 closes to prevent air leakage and maintain the negative pressure within the dust box.
[0055] In some embodiments, the dust box 10 further includes a baffle 14, which is disposed outside the filter assembly 12 to form a structure that completely covers the filter assembly 12. The baffle 14 is used to prevent large particles from being directly impacted into the HEPA paper interlayer of the filter assembly 12 by the high-speed rotating roller brush. An air blowing port is provided at the position corresponding to the second opening 116 on the baffle 14, and the airflow provided by the external power source enters the dust box 10 through the air blowing port and the second opening 116.
[0056] This application also provides a cleaning device, including an external power source 20 and a dust box 10 as described in any of the above embodiments. The external power source 20 can rotate in both directions. When the external power source 20 rotates forward, it provides suction to the dust box, creating a negative pressure to draw debris into the dust box. When collecting dust, the external power source 20 rotates in reverse, blowing air from the second opening 116 into the housing 11 to accelerate the rate at which dust falls off and is discharged from the filter assembly 12.
[0057] In some embodiments, the cleaning device includes a dust box assembly, a vibration assembly, a cover plate, and a bottom shell. The vibration assembly may be disposed on the cover plate, the bottom shell, or both. During dust collection, the vibration of the vibration assembly causes dust on the filter assembly to fall off as quickly as possible. It is worth noting that the vibration assembly here may be the same as the aforementioned vibration assembly, or it may be a different set of vibration assemblies; there is no limitation on this.
[0058] This application proposes a dust box and cleaning device, wherein a vibration component is provided near the filter component of the dust box. The vibration of the vibration component can shake off at least part of the dust accumulated on the filter component into the dust box, thereby ensuring the service life of the filter component and ensuring the smooth airflow during subsequent filtration by the filter component, thus improving the dust collection efficiency of the dust box.
[0059] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the systems or apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple, and relevant parts can be referred to the method section.
[0060] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
