[0028] This application provides a vacuum cleaner dust box, please refer to Figure 1 The dust box of the sweeping machine includes a dust box body 100 and a first filter assembly 231. The dust box body 100 has a collecting chamber formed inside. Figure 2 and Figure 3 The dust box body 100 is provided with a dust suction port 110 and an air outlet 120 connected to the collection chamber. The air outlet 120 is used to connect to the fan. When the fan is running, negative pressure is formed in the collection chamber, and external dust and other debris are sucked into the dust suction port 110. The collection chamber includes a first chamber 210 connected to the dust suction port 110, and a second chamber 220 connected to the air outlet 120.

[0029] The first filter assembly 231 is disposed in the collection chamber, and the first filter assembly 231 is connected to the first chamber 210 and the second chamber 220. That is, the first filter assembly 231 can allow airflow to pass through, and when the airflow passes through the first filter assembly 231, dust in the airflow is filtered. Figure 4 The first filter assembly 231 includes a windward surface 231a and a windward surface 231b, wherein the windward surface 231a faces the first cavity 210, and the windward surface 231b faces the second cavity 220. The first filter assembly 231 is disposed outside the path from the dust suction port 110 to the air outlet 120. Dust, debris and other garbage sucked from the dust suction port 110 can be filtered by the first filter assembly 231 and remain in the collection cavity.

[0030] According to the above description, during the operation of the sweeper, the fan will draw air from the air outlet 120, and the garbage will enter the collection chamber in the dust box body 100 through the dust suction port 110. At this time, the airflow enters the first chamber 210 from the dust suction port 110, then enters the second chamber 220 through the first filter assembly 231, and then is discharged from the air outlet 120. In the present application, the first filter assembly 231 is arranged outside the path from the dust suction port 110 to the air outlet 120, which extends the flow path of the airflow from the dust suction port 110 to the air outlet 120, which is conducive to the dust being sucked into the dust box body 100 and at a distance far from the dust suction port 110, thereby increasing the utilization rate of the space in the dust box body 100.

[0031] In one embodiment, a plurality of first filter assemblies 231 are provided in the collection chamber, and the plurality of first filter assemblies 231 are all provided outside the path from the dust suction port 110 to the air exhaust port 120, and the first chamber 210 is connected to the second chamber 220 through the plurality of first filter assemblies 231. The plurality of first filter assemblies 231 can increase a plurality of different air paths, and dust can be collected at different positions of the collection chamber, further increasing the space utilization rate of the dust box body 100.

[0032] In one embodiment, reference Figure 1 or Figure 5 , two of the plurality of first filter components 231 are arranged opposite to each other and are located at the edges of the two sides of the side wall where the dust suction port 110 is located. In this arrangement, the airflow can enter from the dust suction port 110 and pass through the first filter components 231 located on both sides of the dust suction port 110, and then be discharged from the air outlet 120. Since the first filter components 231 are located at the edges of both sides of the dust suction port 110, the air path can be further extended, and dust can be collected on both sides of the dust suction port 110 and at a position farther from the dust suction port 110, and the space utilization rate in the dust box body 100 is higher.

[0033] In one embodiment, please combine Figure 1 and Figure 4 The dust box of the sweeping machine further includes a first partition 200, the dust suction port 110 is directly opposite to the air exhaust port 120, and the collecting chamber is divided into a first chamber 210 and a second chamber 220 by the first partition 200. Along the direction from the dust suction port 110 to the air exhaust port 120, the first chamber 210 and the second chamber 220 are distributed front and back. Figure 1The first partition 200 includes a middle partition 241 facing the dust suction port 110 and the air outlet 120 and an edge partition 242 connected to the edge of the middle partition 241, and the edge partition 242 is provided with a first filter assembly 231. In this solution, the collection chamber is divided into a first chamber 210 and a second chamber 220 by the first partition 200, and the first filter assembly 231 is arranged on the edge partition 242, so that the first filter assembly 231 is located outside the path from the dust suction port 110 to the air outlet 120. This setting method is simple and easy to implement. The first cavity 210 and the second cavity 220 are distributed front and back, and the dust suction port 110 is directly opposite to the air exhaust port 120, so that the airflow is sucked into the dust suction port 110 and diffuses toward the edge first, and then enters the second cavity 220 in a roundabout way, extending the flow path of the airflow in the collection cavity, which is beneficial for the dust to diffuse toward the edge of the collection cavity and be collected at a position farther away from the dust suction port 110 and the air exhaust port 120, so as to make more effective use of the space in the collection cavity of the dust box.

[0034] In a specific embodiment, the dust box body 100 includes a plurality of side walls surrounding the collection cavity, the plurality of side walls face different directions, one of the plurality of side walls is a first side wall 101 provided with a dust suction port 110, two of the plurality of side walls are a second side wall 102 adjacent to and connected to the first side wall 101, a middle partition 241 is opposite to the first side wall 101, and an edge partition 242 is opposite to the second side wall 102. An edge partition 242 provided with a first filter assembly 231 is opposite to the second side wall 102, and the edge partition 242 is located on both sides of the dust suction port 110. The edge partition 242 can be located at the farthest ends of both sides of the dust box body 100, and two first filter assemblies 231 can be correspondingly arranged at the farthest ends of both sides of the dust suction port 110.

[0035] In one embodiment, Figure 1 As shown, the middle partition 241 is provided with a second filter assembly 232, and the first cavity 210 is also connected to the second cavity 220 through the second filter assembly 232. The second filter assembly 232 is directly opposite to the dust suction port 110 and the air outlet 120, so that a part of the airflow enters the first cavity 210 and directly enters the second cavity 220 through the second filter assembly 232, thereby increasing the number of flow paths for the airflow to flow to the air outlet 120, and further collecting dust at the middle partition 241. The filtering level of the second filter assembly 232 can be the same as that of the first filter assembly 231, and the second filter assembly 232 can use a nylon filter net to filter a larger volume of garbage in the first cavity 210.

[0036] In one embodiment, reference Figure 1, the dust box of the sweeping machine also includes a third filter component 233 arranged in the second cavity 220 and covering the air outlet 120, and the filtering level of the first filter component 231 is lower than the filtering level of the third filter component 233. For example, the first filter component 231 can select a nylon filter, and the third filter component 233 can select HEPA, that is, a high-efficiency air purifier. The first filter component 231 can filter a part of the larger hair, residue, debris, etc., and the third filter component 233 can filter some smaller dust, fine particles in the gas, etc. By filtering at least two layers, dust can be more effectively collected in the dust box body 100. Optionally, the volume of the first cavity 210 is larger than the volume of the second cavity 220, so that a larger volume of dust can be accumulated in the first cavity 210, and a smaller volume of dust can be collected in the second cavity 220, so as to reasonably utilize the space in the dust box body 100. In one embodiment, please refer to Figure 1 and Figure 4 The dust box of the sweeping machine also includes a wind shield 201 arranged in the second cavity 220. The second cavity 220 is divided into a first sub-cavity 221 and a second sub-cavity 222 by the wind shield 201. Both the first sub-cavity 221 and the second sub-cavity 222 are connected to the dust suction port 110 and the air outlet 120. The wind entering the second cavity 220 from the first cavity 210 flows through the first sub-cavity 221 and the second sub-cavity 222 respectively, and is discharged from the air outlet 120. In the second cavity 220, the wind path is changed from one to two parallel wind paths, which increases the number of wind paths and is more conducive to dust collection. The wind shield 201 can isolate the first sub-cavity 221 and the second sub-cavity 222 from each other to prevent wind from moving. Among them, the first cavity 210 is connected to the first sub-cavity 221 through a first filter component 231, and is also connected to the second sub-cavity 222 through another first filter component 231.

[0037] In one embodiment, please combine Figure 3 and Figure 4 The third filter assembly 233 includes an air inlet side 233a facing away from the air outlet 120 and an air outlet side 233b facing the air outlet 120, and the air flow flows from the air inlet side 233a to the air outlet side 233b to achieve filtering. The air inlet side 233a faces the first surface 250 of the first partition 200, and the first surface 250 faces the air outlet 120 and is opposite to the air outlet 120. A gap is provided between the first surface 250 and the third filter assembly 233, and the gap forms an air flow channel in the second cavity 220. In this way, the air path can be extended. The air flow in the second cavity 220 needs to flow to the gap between the air inlet side 233a and the first surface 250, and then flows to the air inlet side 233a of the third filter assembly 233, so that the flow path of the air flow in the second cavity 220 is extended, and the utilization rate of the space in the second cavity 220 is also improved.

[0038] It should be noted that the third filter assembly 233 can be respectively disposed in the first sub-cavity 221 and the second sub-cavity 222. Alternatively, the third filter assembly 233 is configured as an integral structure, with the wind shield 201 as the boundary, with one part located in the first sub-cavity 221 and the other part located in the second sub-cavity 222.

[0039] In one embodiment, please refer to Figure 4 The first partition 200 further includes a connecting partition 243 connecting the middle partition 241 and the edge partition 242. The connecting partition 243 protrudes toward the second cavity 220, forming a space on the side of the first filter assembly 231 facing the first cavity 210. The space allows more airflow to flow toward the first filter assembly 231, and a first filter assembly 231 with a larger area can be arranged on the edge partition 242, thereby increasing the flow area of ​​the airflow from the first cavity 210 to the second cavity 220.

[0040] In one embodiment, the middle partition 241 may protrude toward the first cavity 210 to avoid the third filter assembly 233 located at the air outlet 120. When the third filter assembly 233 is a HEPA filter, since the HEPA filter is relatively thick, for example, 1 cm, the middle partition 241 correspondingly protrudes toward the first cavity 210 by a thickness greater than 1 cm to provide space for the installation of the HEPA filter. Here, the connecting partition 243 protrudes toward the second cavity 220 relative to the middle partition 241.

[0041] In addition, the side of the first partition 200 facing the second cavity 220 and the corners of the first partition 200 can be chamfered or rounded to reduce the wind resistance when the wind passes through the second cavity 220 and increase the wind speed. A first filter assembly 231 can also be provided at the connection partition 243 to increase the air intake area entering the second cavity 220.

[0042] In one embodiment, please refer to Figure 5 The dust box of the sweeper also includes a second partition 300 disposed in the collection chamber, the second partition 300 is connected to the top of the first filter assembly 231, and the collection chamber is divided into a first chamber 210 and a second chamber 220 distributed vertically by the first filter assembly 231 and the second partition 300, the second chamber 220 is located above the first chamber 210, and accordingly, the air outlet 120 is also disposed above the first chamber 210. Figure 6 A fourth filter assembly 234 is disposed in the second cavity 220 and is attached to the air outlet surface 231b. The fourth filter assembly 234 may be a HEPA, i.e., a high-efficiency air purifier.

The second partition 300 includes but is not limited to a U-shaped plate.

[0044] A gap is provided between the air outlet surface 231b of the first filter component 231 and the side wall of the dust box body 100, the first cavity 210 and the second cavity 220 are connected through the gap, and the fourth filter component 234 is arranged in the gap and attached to the air outlet surface 231b, thereby realizing two-stage filtration at the fourth filter component 234.

[0045] Combination Figure 5 , Figure 7 and Figure 8 , the airflow enters the first cavity 210 from the suction port 110, and is double-filtered by the first filter assembly 231 and the fourth filter assembly 234, and then enters the second cavity 220 located at the top of the first cavity 210, and then is discharged from the air outlet 120. The second cavity 220 is located at the top of the first cavity 210, which can effectively utilize the space in the height direction of the dust box body 100 and reduce the floor space of the dust box body 100. The second cavity 220 can be composed of the space between the air outlet surface of the fourth filter assembly 234 and the side wall of the dust box body 100, and the long strip air duct surrounded by the second partition 300, and the two are connected through the connecting port 310.
