[0038] Please refer to Figure 1 、 2 As shown in FIGS. 10 and 11, a fixing seat 12 is provided at the upper end of the cover body 10. The fixing seat 12 is arranged above the air outlet 11 and communicates with the air outlet 11. The fixing seat 12 is used to fix the filter assembly 30. Among them, the filter assembly 30 can be in various forms, such as a HEPA filter element, a combination form of a HEPA filter element and other filter elements, etc.
[0039] A fixing cover 40 is detachably assembled on the fixing seat 12 to effectively fix the filter assembly 30. The fixing cover 40 is provided with ventilation holes 41 to allow air flow. The fixing cover 40 can be detachably connected to the fixing seat 12 by means of rotary clamping, or can be detachably connected to the fixing seat 12 by means of sealing and tight fitting. The detachable methods between the two are not limited to the above two methods and can be the same as the prior art, which will not be elaborated here.
[0040] The cover body 10 is detachably assembled on the barrel body 50 of the dust-absorbing trash can. The detachable assembly method between the cover body 10 and the barrel body 50 is the same as the prior art and will not be elaborated here.
[0041] A dust collection chamber 51 for collecting dust is provided inside the barrel body 50. An intake pipe 52 communicating the inside and outside of the barrel body 50 is provided on the barrel body 50. The intake pipe 52 is longitudinally arranged.
[0042] When the cover body 10 is assembled on the barrel body 50, the lower end of the cover body 10 is directly mounted on the outer cylinder 60. A first chamber 61 for air flow is provided inside the outer cylinder 60. The outer cylinder 60 is arranged inside the barrel body 50. The outer cylinder 60 can be arranged inside the dust collection chamber 51, that is, the dust collection chamber 51 is annularly arranged around the outer periphery of the outer cylinder 60. Please refer to Figure 1 、 3As shown, the outer cylinder 60 can also be provided on one side of the dust collection chamber 51, or the dust collection chamber 51 is semi - surrounded on the outer periphery of the outer cylinder 60. At this time, the outer cylinder 60 can be integrally provided with the inner peripheral wall of the barrel body 50. Please refer to Figure 10 、 13 As shown, the outer cylinder 60 is provided with a dust outlet 62. The dust outlet 62 is used to connect the first chamber 61 and the dust collection chamber 51. The hollow protrusion 20 extends into the first chamber 61, and the first chamber 61 is connected to the air outlet 11 through the first through - hole 23.
[0043] Please refer to Figure 1 、 8 As shown in FIGS. 9, a detachable connection method between the outer cylinder 60 and the cover body 10 is as follows: A limiting hollow protrusion 63 is provided on the outer periphery of the outer cylinder 60. The limiting hollow protrusion 63 can be columnar, block - shaped, dot - shaped, or even other shapes. In this embodiment, the limiting hollow protrusion 63 is columnar. A connecting seat 13 is provided at the lower end of the cover body 10. A plurality of clamping grooves 131 are evenly arranged in a ring on the connecting seat 13. The clamping grooves 131 are adapted to the limiting hollow protrusion 63. The clamping grooves 131 are in an inverted L - shape. The limiting hollow protrusion 63 can be inserted into the second clamping groove 131 and locked in the second clamping groove 131 along the second clamping groove 131 to realize the rotational clamping connection between the outer cylinder 60 and the cover body 10. Rotating the outer cylinder 60 or the cover body 10 in the reverse direction can disassemble the two. After the outer cylinder 60 and the cover body 10 are assembled, the upper end of the outer cylinder 60 abuts against the lower end surface of the cover body 10. Or after the cover body 10 and the barrel body 50 are assembled, the upper end of the outer cylinder 60 directly abuts against the lower end of the cover body 10, and there can be no other connecting structures between the two.
[0044] A flow - guiding module 70 is provided inside the outer cylinder 60. The flow - guiding module 70 includes an inner cylinder 71 and a flow - guiding block 72. A dust inlet 64 longitudinally penetrating the bottom of the inner cylinder 71 is provided at the bottom of the outer cylinder 60. The upper end of the inner cylinder 71 is closed. A second chamber 73 for air flow is provided inside the inner cylinder 71. The second chamber 73 is connected to the dust inlet 64. A second through - hole 74 is provided on the side surface of the inner cylinder 71. The second through - hole 74 connects the first chamber 61 and the second chamber 73. The dust inlet pipe 52 is axially arranged from the bottom of the barrel body 50. The outer cylinder 60 is mounted on the dust inlet pipe 52, and the dust inlet pipe 52 is coaxially connected to the dust inlet 64.
[0045] When the hollow protrusion 20 is in a cylindrical shape, the lower end of the hollow protrusion 20 is close to or in contact with the upper end of the inner cylinder 71. Please refer to Figure 1 As shown, when the second part 22 is in a conical shape, a groove 75 formed by downward depression is provided on the upper end surface of the inner cylinder 71. The lower end of the second part 22 extends into the groove 75, or a third part 24 is provided at the lower end of the second part 22, and the third part 24 extends into the groove 75. The radius of the third part 24 preferably gradually decreases from top to bottom. Please refer to Figure 10 As shown. When the second part 22 is conical, the separation effect of dust and other garbage in the first chamber 52 is better than that of the cylindrical shape of the second part 22.
[0046] A flow guiding block 72 is provided with a flow guiding surface 76 arranged circumferentially along the outer peripheral wall of the inner cylinder 71. One end of the flow guiding surface 76 is communicated with the second through hole 74, and one end of the flow guiding surface 76 spirally ascends towards the other end. The dust outlet 62 is arranged in the tangential direction of the flow guiding surface 76. The air flow longitudinally enters the second chamber 73 from the dust inlet 64, then transversely enters the first chamber 61 through the second through hole 74, and is separated in the first chamber 61 along the flow guiding surface 76. The separated dust passes through the dust outlet 62 and is collected in the dust collection chamber 51, and the separated air flow flows upward through the first through hole 23 and is discharged upward through the air outlet 11. Of course, the separation method of the air flow in the first chamber 61 is not limited to the above one. For example, other forms of flow guiding modules can be arranged in the first chamber 61 to enable the separation of the air flow and the dust.
[0047] The dust outlet 62 can be one or multiple. When there are multiple dust outlets 62, the multiple dust outlets 62 are annularly arrayed on the peripheral wall of the outer cylinder 60. Regardless of the number of dust outlets, the dust outlet 62 is higher than the second part 22 in the vertical direction. Please refer to Figure 1 、 3 As shown in FIGS. 5, 10, 13, and 14, the dust outlet 62 is one and is formed by recessing downward from the upper end of the outer cylinder 60. The lower end of the cover body 10 closes the upper end of the dust outlet 62. The longitudinal distance from the bottom wall of the dust outlet 62 to the lower end of the cover body 10 is h1, and the longitudinal distance from the highest point of the second part 22 to the lower end of the cover body 10 is h2, and h1 < h2. Such a setting enables the dust to pass through the dust outlet 62 as much as possible instead of passing through the first through hole 23 on the hollow protrusion 20. The connecting seat 13 is provided with a notch 132 corresponding to the dust outlet 62, which facilitates the dust passing through the dust outlet 62 to enter the dust collection chamber 51.
[0048] The air flow carrying dust longitudinally enters the second chamber 73 along the dust inlet pipe 52 and the dust inlet 64 in sequence, and transversely passes through the second chamber 73 and enters the first chamber 61, flows upward and separates under the action of the flow guiding module 70. The dust enters the dust collection chamber 52 through the dust outlet 62 for collection. The separated air flow passes through the first through hole 23 and flows upward through the air outlet 11. The filtering component 60 filters the air flow passing through the air outlet 11 again, and then discharges it through the air outlet of the bucket cover. Through the setting of the hollow protrusion 20 and the first through hole 23, the air flow in the first chamber 52 is prevented from directly passing through the air outlet 11, enabling the effective separation of the air flow in the first chamber 52.
[0049] 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 protection scope of the present application.
