[0027] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices, systems, devices, and methods consistent with some aspects of the present application.

[0028] As Figures 1 to 10 shown, a top cover assembly of a dust-absorbing trash can according to the present application includes a cylinder body 20 and a top cover 10. The cylinder body 20 is disposed inside the barrel body 40 of the dust-absorbing trash can. The top cover 10 can be detachably covered on the upper end of the barrel body 40. The top cover 10 and the barrel body 40 form a barrel inner cavity 41 for collecting dust and other garbage. A connecting portion 11 is provided at the lower end of the top cover 10, and the cylinder body 20 is provided with a clamping portion that can be rotationally clamped with the connecting portion 11. When the cylinder body 20 and the top cover 10 are clamped, the upper end surface of the cylinder body 20 abuts against the lower end surface of the top cover 10.

[0029] Through the separate settings of the cylinder body 20, the top cover 10, and the barrel body 40, the disassembly and assembly between the cylinder body 20 and the top cover 10 and between the top cover 10 and the barrel body 40 are facilitated, the assembly efficiency is improved, and the cleaning of the inside of the cylinder body 20 and the barrel inner cavity 41 is convenient.

[0030] Specifically, a first chamber 21 for air flow is provided inside the cylinder body 20. The upper end of the cylinder body 20 is open, and a dust-throwing port is provided on the cylinder body 20. The dust-throwing port communicates the first chamber 21 with the barrel inner cavity 41. The dust-throwing port is generally adjacent to the upper end of the cylinder body 20. The dust-throwing port can be one or multiple. When there are multiple dust-throwing ports, they are arranged in a circular array on the side wall of the cylinder body 20.

[0031] Among them, a flow guiding module 30 is provided inside the cylinder body 20. The flow guiding module 30 includes an inner cylinder 31. A dust inlet 22 longitudinally penetrating the bottom of the inner cylinder 31 is provided at the bottom of the cylinder body 20. A second chamber 32 for air flow is provided inside the inner cylinder 31. The second chamber 32 is communicated with the dust inlet 22. An air outlet 33 is provided on the side surface of the inner cylinder 31. The air outlet 33 communicates the first chamber 21 with the second chamber 32.

[0032] In this embodiment, a flow guiding block 34 is provided on the outer periphery of the inner cylinder 31. A flow guiding surface 35 is provided on the flow guiding block 34 and is arranged circumferentially along the outer peripheral wall of the inner cylinder 31. One end of the flow guiding surface 35 is communicated with the air outlet 33. One end of the flow guiding surface 35 spirally ascends towards the other end. The dust throwing port is arranged in the tangential direction of the flow guiding surface 35. The air flow longitudinally enters the second chamber 32 from the dust inlet 22, then laterally enters the first chamber 21 through the air outlet 33, and is separated in the first chamber 21 along the flow guiding surface 35. The separated dust and other garbage pass through the dust throwing port and are collected in the inner cavity 41 of the barrel body. The separated air flow flows upward and passes out of the upper end of the barrel body 20. Of course, the separation method of the air flow in the first chamber 31 is not limited to the above one. For example, other forms of flow guiding modules can be arranged in the first chamber 31 to enable the separation of the air flow and the dust.

[0033] A ventilation port 12 is provided on the top cover 10. A second notch 111 and a plurality of first clamping grooves are provided on the connecting portion 11. The first clamping grooves are arranged in a ring shape on the connecting portion 11. The ventilation port 12 is arranged inside the connecting portion 11.

[0034] Please refer to Figures 8 to 10 As shown, a specific setting method of the first clamping groove: The first clamping groove includes a clamping portion 112 and a locking portion 113. The clamping portion 112 vertically extends upward from the lower end of the connecting portion 13. The locking portion 113 is vertically communicated with the upper end of the clamping portion 112, so that the first clamping groove is L-shaped. The first clamping groove horizontally penetrates through the connecting portion 11. A locking protrusion 114 protrudes upward from the lower end surface of the locking portion 113. The locking protrusion 114 and the end of the locking portion 113 away from the clamping portion 112 form a locking space. Of course, the locking protrusion 114 can also protrude downward from the upper end surface of the locking portion 113, or the locking protrusion 114 is L-shaped to form a hook portion, etc.

[0035] Correspondingly, a plurality of first limiting protrusions are provided on the outer periphery of the barrel body 20. The first limiting protrusions are adapted to the first clamping grooves. The first limiting protrusions can be columnar, block-shaped, or even dot-shaped, or other shapes. In this embodiment, the first limiting protrusion is a cylindrical clamping post 23. During assembly, the clamping post 23 is inserted into the clamping portion 132 from bottom to top until the clamping post 23 abuts against the upper end of the clamping portion 132. Then, the barrel body 20 or the top cover 10 is rotated to make the clamping post 23 rotate laterally and cross over the locking protrusion 134 and be inserted into the locking space, so that the barrel body 20 and the top cover 10 are clamped. When disassembly is required, only the top cover 10 or the barrel body 20 needs to be rotated in the reverse direction. After assembly, the upper end of the barrel body 20 abuts against the lower end surface of the top cover 10. The first chamber 21 is communicated with the ventilation port 12. The air flow separated in the first chamber 21 flows upward and is discharged from the ventilation port 12.

[0036] In order to reduce the probability of dust being directly discharged from the ventilation opening 12, an extension part 13 is provided at the lower end of the top cover 10. A plurality of air inlet holes 131 are provided on the outer periphery of the extension part 13. The extension part 13 extends into the first chamber 21. The first chamber 21 is communicated with the ventilation opening 12 through the air inlet holes 131, so that the air flow in the first chamber 21 can pass through the air inlet holes 131 and be discharged from the ventilation opening 12.

[0037] Among them, the extension part 13 includes a first part 132 and a second part 133 that are sequentially communicated. The upper end of the first part 132 is connected to the lower end of the top cover 10, the lower end of the first part 132 is connected to the second part 133, and the air inlet holes 131 are provided on the second part 133. The extension part 13 is cylindrical, that is, the radius of the extension part 13 is substantially equal from top to bottom. Please refer to Figure 1 、 9 as shown. Of course, the extension part 13 can also be other shapes. For example, the extension part 13 is conical, or the first part 132 is cylindrical and the second part 133 is conical, where the radius of the cone gradually decreases from top to bottom, or both the first part 132 and the second part 133 are conical, but the inclination angle of the second part 133 is greater than that of the first part 132. When the second part 133 is conical, compared with the second part 133 being cylindrical, the separation effect of dust and other garbage in the first chamber 21 is better.

[0038] In this embodiment, the dust throwing opening is the first notch 24. The first notch 24 is recessed downward from the upper end of the cylinder body 20, and the first notch 24 corresponds to the second notch 111. The lower end surface of the top cover 10 closes the upper end of the first notch 24. Please refer to Figure 1 as shown. The longitudinal distance from the bottom wall of the first notch 24 to the lower end surface of the top cover 10 is h1, and the vertical height of the first part 132 is h2, that is, the longitudinal distance from the lowest point of the first part 132 to the lower end surface of the top cover 10 is h2, and h1 < h2, that is, the first notch 24 is higher than the second part 133 in the vertical direction. Such a setting can make the dust in the first chamber 21 be discharged from the first notch 24 as much as possible, reducing the probability of the dust in the first chamber 21 directly passing through the air inlet holes 131 and being discharged.

[0039] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of protection of the present application.
