The dust collecting device 100 further comprises a detachable bottom wall body 3, wherein a part of the bottom wall body 3 forms the bottom wall of the right chamber 1, and another part of the bottom wall body 3 forms the bottom wall of the lower chamber 22, and the bottom wall body 3 is used for facilitating the cleaning of the garbage in the left chamber 2 and the right chamber 1; a first filter 4 is provided in a flow path before the air enters the lower chamber 22, a second filter 5 is provided in the lower chamber 22, and a third filter 41 is provided in a flow path after the air exits the lower chamber 22, wherein the first filter 4 is a primary filter, the second filter 5 is a cyclone filter, and the third filter 41 is a high efficiency filter.
The structure of the dust collecting device 100 will be further described with reference to the accompanying drawings:
as shown in fig. 1, fig. 2, fig. 3 and fig. 4, the dust collecting device 100 includes a left chamber 2 and a right chamber 1 which are communicated with each other and arranged left and right, a partition wall 23 is provided in the left chamber 2, the partition wall 23 divides the left chamber 2 into the upper chamber 21 and the lower chamber 22, so that the three chambers of the upper chamber 21, the lower chamber 22 and the right chamber 1 do not need to be arranged side by side in a straight line, thereby reducing the total height of the three chambers, and being beneficial to reducing the height space occupied by the dust collecting device 100 on the sweeping robot, and having simple structure and convenient manufacture. The partition wall 23 is provided with a wind passing wall hole 230 communicating the upper chamber 21 and the lower chamber 22, a baffle 231 extending toward the lower chamber 22 is provided on the periphery of the wind passing wall hole 230, the baffle 231 is annularly arranged, and the wind passing wall hole 230 is located in an annular space defined by the baffle 231. The dust collecting apparatus 100 further comprises a detachable bottom wall 3, wherein a part of the bottom wall 3 forms a bottom wall of the right chamber 1, and another part of the bottom wall 3 forms a bottom wall of the lower chamber 22. The lower chamber 22 is provided with a second stage filter 5, and the second stage filter 5 is detachably locked between the partition wall 23 and the bottom wall 3. Therefore, the second-stage filter 5 can be conveniently cleaned or replaced, and the phenomenon that a large amount of dust particles are adhered to the second-stage filter 5 to breed bacteria and destroy the dust filtering effect after long-term use is avoided.
As shown in fig. 4, 5 and 6, the second stage filter 5 is a cyclone centrifugal filter. The second stage filter 5 comprises a conical body 51 and a bottom cylinder 52 which is connected with the lower surface of the conical body 51, wherein the inner cavity of the bottom cylinder 52 is communicated with the inner cavity of the conical body 51. The upper and lower ends of the conical body 51 are both open structures, the diameter of the upper end opening 511 of the conical body 51 is larger than that of the lower end opening 512, the bottom end of the bottom cylinder 52 is provided with an opening 521, and the bottom end of the bottom cylinder 52 is connected to the bottom wall 3. In addition, a sealing device is arranged between the bottom end of the bottom cylinder 52 and the bottom wall body 3, so that the dust separation and precipitation efficiency of the dust collecting device can be enhanced. The lower end of the cone 51 extends into the bottom cylinder 52. The cone body 51 and the bottom cylinder 52 adopt an integrated structure to form a cyclone centrifugal cone, and a plurality of cyclone centrifugal cones form the second-stage filter 5. Of course, in other embodiments, the second stage filter 5 may be formed by a cyclone cone, and the cone 51 and the bottom cylinder 52 may be of a split structure. An upper end air inlet duct (53, 53 a) is arranged on the upper end part of the conical body 51, and the upper end air inlet duct (53, 53 a) is used for enabling air to form cyclone in the inner cavity of the conical body 51. The baffle 231 extends into the inner cavity of the cone 51, the baffle 231 is opposite to the inner cavity wall 513 of the cone 51, the baffle 231, the inner cavity wall 513 of the cone 51 and the separation wall 23 arranged between the baffle 231 and the inner cavity wall of the cone 51 form a cyclone channel 54 which is annularly arranged, and the air outlet (530, 530 a) of the upper end air inlet channel (53, 53 a) is positioned in the range defined by the cyclone channel 54 and communicated with the cyclone channel 54. The air entering the lower chamber 22 from the right chamber 1 passes through the upper air inlet duct (53, 53 a) and then enters the inner cavity of the cone 51 to form a cyclone under the guidance of the cyclone passage 54, and since the diameter of the upper end opening 511 of the cone 51 is larger than the diameter of the lower end opening 512, the centrifugal force of the air flow entering the inner cavity of the cone 51 is larger when the air flow is blown from top to bottom in a spiral manner, and the dust particles are thrown out by the centrifugal force of the cyclone to be separated from the air flow and enter the inner cavity of the bottom cylinder 52. Since the lower end of the cone 51 extends into the bottom cylinder 52, the dust particles entering the inner cavity of the bottom cylinder 52 are difficult to re-enter the inner cavity of the cone 51 through the lower opening 512 of the cone 51. The airflow with the dust particles filtered out sequentially passes through the inner channel of the baffle 231 and the air wall holes 230, is discharged from the inner cavity of the cone 51, and enters the upper chamber 21.
As shown in fig. 4, a first stage filter 4 is provided in the flow path before entering the lower chamber 22. The first stage filter 4 may be disposed within the right chamber 1. In the present embodiment, the first filter stage 4 is disposed between the right chamber 1 and the lower chamber 22. The partition wall 23 and the bottom wall body 3 are further provided with an upper clamping groove and a lower clamping groove (232 and 31), the upper clamping groove 232 is opposite to the lower clamping groove 31, the first-stage filter 4 is clamped between the upper clamping groove 232 and the lower clamping groove 31, and the second-stage filter 5 and the first-stage filter 4 are arranged at intervals from left to right. The first filter 4 is a primary filter such that the first filter 4 is used to primarily filter the waste and filter out a large portion of the relatively large volume of waste to be retained in the right chamber 1 outside the lower chamber 22.
As shown in fig. 2 and 4, a third filter 41 is provided in the flow path after flowing out of the lower chamber 22. The tertiary filter 41 is within the upper chamber 21. The third filter 41 is a high efficiency filter for the final stage of filtering the garbage, and can filter out the garbage with smaller volume and retain the garbage in the upper chamber 21. In order to facilitate cleaning or replacement of the third filter 41, the third filter 41 is detachably locked in the upper chamber 21. A handle 411 is provided on the third filter 41, and the handle 411 is used for a person to apply force to detach the third filter 41 from the upper chamber 21.
The filtering of the waste by the first filter 4 tends to be relatively large, and the filtering of the waste by the second filter 5 and the third filter 41 tends to be relatively small, which obviously does not facilitate the effective utilization of the dust collecting space of the dust collecting device 100 if the upper chamber 21, the lower chamber 22 and the right chamber 1 are provided with the same volume. In view of this, a further solution is that the volume of the right chamber 1 is greater than the volume of the lower chamber 22 and also greater than the volume of the upper chamber 21. Therefore, the volume of the right chamber 1, the volume of the upper chamber 21 and the volume of the lower chamber 22 are reasonably arranged, so that the utilization rate of the dust collecting space of the dust collecting device 100 can be improved, and the overall volume of the dust collecting device 100 can be reduced.
As shown in fig. 2, 7 and 8, the bottom wall 3 is detachable. The way of disassembling the bottom wall body 3 may be various, for example, it may be completely separated from the left and right chambers 2 and 1 without connection, and in this embodiment, the bottom wall body 3 is connected to the left chamber 2 in a hinged manner and can open the bottoms of the left and right chambers 2 and 1 in a turnover manner.
