DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0027] Please refer to Figure 1-Figure 3 As shown, in the first aspect, the present application proposes a cyclone separation structure 15, which can effectively separate garbage such as large-volume paper scraps and other garbage such as small-volume dust and other garbage in the object to be adsorbed.

[0028] The cyclonic separation structure 15 is applied to the dust bin module 10, which includes a bin body 11; the bin body 11 has a dust collection chamber (not shown) for storing the object to be adsorbed, and a fluid inlet 11a connected to the dust collection chamber. The cyclonic separation structure 15 includes a first separation cover 151, a second separation cover 152, a barrier 153, and a filter assembly 154. The first separation cover 151 is located in the dust collection chamber and is used to connect to the bin body 11. The second separation cover 152 is arranged in the cavity of the first separation cover 151, and the air inlet 152a of the second separation cover 152 is arranged near the air outlet 152b of the second separation cover 152. The barrier 153 is arranged corresponding to the air outlet 152b of the second separation cover 152 and at least partially extends into the cavity of the second separation cover 152 to separate the air outlet 152b of the second separation cover 152 from the air inlet 152a of the second separation cover 152. The filter assembly 154 is disposed outside the second separation cover 152 and is located on a side of the second separation cover 152 where the air outlet 152 b is located.

[0029] The following combination Figures 1-8 The specific structure of the cyclone separation structure 15 is introduced in detail.

[0030] like Figure 1-Figure 2 As shown, the cyclone separation structure 15 is applied to the dust bin module 10 , and the dust bin module 10 serves as a garbage recycling station of the convenient vacuum cleaner 1 . The dust bin module 10 includes a bin body 11 .

[0031] The bin body 11 serves as the shell of the dust bin module 10. There is no limitation on the specific material of the bin body 11, and designers can make reasonable choices based on actual needs. For example, the material of the bin body 11 can be, but is not limited to, plastic or aluminum alloy. There is no limitation on the specific shape of the bin body 11, and designers can make reasonable designs based on actual needs. For example, the shape of the cross section of the bin body 11 can be, but is not limited to, circular or rectangular.

[0032] The bin body 11 has a dust collecting chamber, which is a space inside the bin body 11 for storing objects to be adsorbed; wherein, the objects to be adsorbed can be but are not limited to garbage such as dust or paper scraps.

[0033] The bin body 11 also has a fluid inlet 11a that communicates with the dust collection chamber. The "fluid inlet 11a" is an opening in the bin body 11 for allowing dust or paper scraps, for example, to enter the dust collection chamber. The specific shape of the fluid inlet 11a is not limited herein, and designers can reasonably design it based on actual needs. For example, the cross-sectional shape of the fluid inlet 11a can be, but is not limited to, circular or rectangular.

[0034] like Figure 3-Figure 4As shown, the cyclone separation structure 15 includes a first separation cover 151 , a second separation cover 152 , a barrier 153 and a filter assembly 154 .

[0035] The first separation cover 151 serves as the outer separation member of the cyclone separation structure 15 and is used to effectively separate large-volume waste, such as paper scraps, from small-volume waste, such as dust, in the object to be adsorbed. The first separation cover 151 is located within the dust collection chamber of the bin body 11. The specific structure of the first separation cover 151 is not limited here, and designers can reasonably design it according to actual needs. For example, the first separation cover 151 is a quasi-circular cylindrical structure, and the peripheral side surface of the first separation cover 151 is provided with a plurality of through holes 151a, and the plurality of through holes 151a are arranged in M ​​rows and N columns around the central axis of the first separation cover 151. In this way, under the suction action of the main fan 46 of the fan main module 40 of the convenient vacuum cleaner 1, garbage such as dust or paper scraps flows from the fluid inlet 11a of the bin body 11 into the dust collecting chamber of the bin body 11, among which small-volume dust and other garbage can pass through the through hole 151a of the first separation cover body 151 and enter the cavity of the first separation cover body 151, while large-volume paper scraps and other garbage cannot pass through the through hole 151a of the first split cover body and are blocked in the channel between the inner peripheral side of the bin body 11 and the outer peripheral side of the first separation cover body 151.

[0036] The first separation cover body 151 is used to connect with the warehouse body 11; the specific connection method between the first separation cover body 151 and the warehouse body 11 is not limited here, and designers can make reasonable designs according to actual needs; for example, the first separation cover body 151 can be, but is not limited to, detachably connected to the warehouse body 11 by at least one of screw connection, snap connection or plug-in connection; for another example, the first separation cover body 151 can be, but is not limited to, non-detachably connected to the warehouse body 11 by gluing.

[0037] The second separation cover 152 serves as an inner separation member of the cyclone separation structure 15 and is used to effectively separate large dust particles from small dust particles, such as dust particles, that enter the cavity of the second separation cover 152. The specific structure of the second separation cover 152 will be described in detail below.

[0038] The second separation cover 152 is arranged in the cavity of the first separation cover 151, so that the second separation cover 152 and the first separation cover 151 form an inner and outer nested structure. The specific connection method of the second separation cover 152 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the second separation cover 152 can be connected to the first separation cover 151. In this case, the second separation cover 152 can be, but not limited to, detachably connected to the first separation cover 151 by at least one of screw connection, snap connection or plug-in connection, or the second separation cover 152 can be, but not limited to, non-detachably connected to the first separation cover 151 by gluing connection; for another example, the second separation cover 152 can also be used to connect to the warehouse body 11. In this case, the second separation cover 152 can be, but not limited to, detachably connected to the warehouse body 11 by at least one of screw connection, snap connection or plug-in connection, or the second separation cover 152 can be, but not limited to, non-detachably connected to the warehouse body 11 by gluing connection.

[0039] The air inlet 152a of the second separation cover body 152 is arranged close to the air outlet 152b of the second separation cover body 152; for example, the second separation cover body 152 has a cylindrical structure, the air outlet 152b of the second separation cover body 152 is located at the cylindrical end face of the second separation cover body 152, and the air inlet 152a of the second separation cover body 152 is located at one end of the cylindrical side face of the second separation cover body 152 close to the cylindrical end face.

[0040] like Figure 3-Figure 4 As shown, the barrier 153 serves as another inner separation member of the cyclone separation structure 15, and cooperates with the second separation cover 152 to effectively separate large dust particles from small dust particles, such as dust particles, that enter the cavity of the second separation cover 152. The specific structure of the barrier 153 will be described in detail below.

[0041] The barrier 153 is provided corresponding to the air outlet 152b of the second separation cover 152. The specific connection method of the barrier 153 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the barrier 153 can be connected to the second separation cover 152, and in this case, the barrier 153 can be, but not limited to, detachably connected to the second separation cover 152 by at least one of screw connection, snap connection or plug connection, or, the barrier 153 can be, but not limited to, non-detachably connected to the second separation cover 152 by gluing; for another example, the barrier 153 can also be connected to the first separation cover 151, and in this case, the barrier 153 The barrier 153 may be, but is not limited to, detachably connected to the first separation cover 151 by at least one of screw connection, snap connection or plug-in connection, or the barrier 153 may be, but is not limited to, non-detachably connected to the first separation cover 151 by gluing connection; for another example, the barrier 153 may also be used to connect to the warehouse body 11, in which case the barrier 153 may be, but is not limited to, detachably connected to the warehouse body 11 by at least one of screw connection, snap connection or plug-in connection, or the barrier 153 may be, but is not limited to, non-detachably connected to the warehouse body 11 by gluing connection.

[0042] At least a portion of the barrier 153 extends into the cavity of the second separation cover 152 to separate the air outlet 152b of the second separation cover 152 from the air inlet 152a of the second separation cover 152. Thus, under the suction action of the main fan 46 of the fan main module 40 of the portable vacuum cleaner 1, dust, for example, flows from the air inlet 152a of the second separation cover 152 into the cavity of the second separation cover 152, where large dust particles, for example, settle to the bottom of the second separation cover 152, while small dust particles, for example, continuously move in the channel between the outer peripheral side of the barrier 153 and the inner peripheral side of the second separation cover 152, and eventually pass over the barrier 153 and move toward the air outlet 152b of the second separation cover 152. It should be noted that, for example, after the dust flows into the cavity of the second separation cover body 152 from the air inlet 152a of the second separation cover body 152, the wind speed of the main fan 46 of the fan main module 40 of the convenient vacuum cleaner 1 can be adjusted so that large particles of dust are directly settled to the bottom of the second separation cover body 152, and small particles of dust are moved over the barrier 153 toward the air outlet 152b of the second separation cover body 152, thereby achieving the effect of effectively separating large particles of dust from small particles of dust, and effectively reducing the possibility of large particles of dust passing over the barrier 153 and moving toward the air outlet 152b of the second separation cover body 152 and clogging the filter component 154.

[0043] The filter assembly 154 is a structural component of the cyclone separation structure 15 for filtering, for example, small particles of dust. The specific structure of the filter assembly 154 will be described in detail below.

[0044] The filter assembly 154 is disposed outside the second separation cover 152 and is located on the side of the second separation cover 152 where the air outlet 152b is located. The specific connection method of the filter assembly 154 is not limited here, and designers can reasonably design it according to actual needs. For example, the filter assembly 154 can be, but is not limited to, detachably connected to the second separation cover 152 / first separation cover 151 / tank body 11 by at least one of screw connection, snap connection, or plug connection.

[0045] It should be noted that the first separation cover 151 is used as a primary separation to effectively separate garbage such as large-volume paper scraps and garbage such as small-volume dust in the object to be adsorbed; the second separation cover 152 and the barrier 153 are used as a secondary separation to effectively separate large particles of dust and small particles of dust in the dust that enter the cavity of the second separation cover 152; the filter component 154 is used as a third separation to effectively separate small particles of dust from the airflow to achieve the effect of purifying the airflow.

[0046] Based on the cyclone separation structure 15 in the embodiment of the present application, by designing the first separation cover 151, the first separation cover 151 can effectively separate garbage such as large-volume paper scraps and garbage such as small-volume dust in the object to be adsorbed. By designing the second separation cover 152 and the barrier 153, the second separation cover 152 and the barrier 153 cooperate, for example, dust flows from the air inlet 152a of the second separation cover 152 into the cavity of the second separation cover 152, wherein, for example, large particles of dust will settle to the bottom of the second separation cover 152, while, for example, small particles of dust will continuously move in the channel between the outer peripheral side of the barrier 153 and the inner peripheral side of the second separation cover 152, and finally pass over the barrier 153 and move toward the air outlet 152b of the second separation cover 152, thereby achieving effective separation of large particles of dust and small particles of dust, and reducing the possibility of large particles of dust clogging the filter assembly 154. By designing the filter assembly 154 , the filter assembly 154 can effectively separate small particles of dust from the wind flow, thereby achieving the effect of purifying the wind flow.

[0047] Further, if Figure 3-Figure 4As shown, the barrier member 153 includes a barrier tube 153a extending into the cavity of the second separation cover 152. The barrier tube 153a is connected to the air outlet 152b of the second separation cover 152, and the outer peripheral side of the barrier tube 153a is spaced apart from the inner peripheral side of the second separation cover 152. Thus, under the suction action of the main fan 46 of the fan main module 40 of the portable vacuum cleaner 1, dust, for example, flows from the air inlet 152a of the second separation cover 152 into the cavity of the second separation cover 152. Large dust particles, for example, settle to the bottom of the second separation cover 152, while small dust particles, for example, continuously move in the channel formed between the outer peripheral side of the barrier tube 153a and the inner peripheral side of the second separation cover 152, and eventually pass over the tube wall of the barrier tube 153a and flow from the cavity of the barrier tube 153a to the air outlet 152b of the second separation cover 152.

[0048] Of course, the barrier 153 may also include a barrier plate (not shown) extending into the cavity of the second separation cover 152, with the barrier plate facing the air inlet 152a of the second separation cover 152 and spaced from the inner peripheral side surface of the second separation cover 152. In this way, under the suction action of the main fan 46 of the fan main module 40 of the convenient vacuum cleaner 1, dust, for example, flows from the air inlet 152a of the second separation cover 152 into the cavity of the second separation cover 152, wherein large dust particles, for example, settle to the bottom of the second separation cover 152, while small dust particles, for example, continuously move in the channel formed between the barrier plate and the inner peripheral side surface of the second separation cover 152, and eventually pass over the barrier plate and move toward the air outlet 152b of the second separation cover 152.

[0049] When the barrier 153 includes a barrier tube 153 a , the specific design of the dimensions of the barrier tube 153 a and the second separation cover 152 may include, but is not limited to, one or more of the following embodiments.

[0050] like Figure 5As shown, in the first embodiment, along a direction parallel to the plane where the air outlet 152b of the second separation cover 152 is located, the inner diameter of the second separation cover 152 is D1, and the inner diameter of the baffle tube 153a is D2; and 0.3 ≤ D2 / D1 ≤ 0.8. For example, the specific value of D2 / D1 can be, but is not limited to, 0.3, 0.4, 0.5, 0.6, 0.7, or 0.8; preferably, D2 / D1 = 0.5. By rationally designing the ratio of the inner tube diameter D2 of the blocking tube 153a and the inner tube diameter D1 of the second separation cover 152, under the suction action of the main fan 46 of the fan main module 40 of the convenient vacuum cleaner 1, the separation effect of large dust particles and small dust particles is improved, and the possibility of large dust particles passing over the tube wall of the blocking tube 153a and flowing from the cavity of the blocking tube 153a to the air outlet 152b of the second separation cover 152 and clogging the filter component 154 can be further effectively reduced.

[0051] like Figure 5 As shown, in the second embodiment, along a direction parallel to the plane where the air outlet 152b of the second separation cover 152 is located, the inner diameter of the second separation cover 152 is D1, and the diameter of the air inlet 152a of the second separation cover 152 is D3; and 0.2≤D3 / D1≤0.5. For example, the specific value of D3 / D1 can be, but is not limited to, 0.2, 0.3, 0.4, or 0.5; preferably, D3 / D1=0.3. By rationally designing the ratio of the diameter D3 of the air inlet 152a of the second separation cover body 152 and the inner tube diameter D1 of the second separation cover body 152, under the suction action of the main fan 46 of the fan main module 40 of the convenient vacuum cleaner 1, the separation effect of large dust particles and small dust particles is improved, and the possibility of large dust particles passing over the tube wall of the blocking tube 153a and flowing from the cavity of the blocking tube 153a to the air outlet 152b of the second separation cover body 152 and clogging the filter component 154 can be further effectively reduced.

[0052] like Figure 6As shown, in the third embodiment, the inner diameter of the second separation cover 152 is D1 along a direction parallel to the plane where the air outlet 152b of the second separation cover 152 is located; the length of the baffle tube 153a is H1 along a direction perpendicular to the plane where the air outlet 152b of the second separation cover 152 is located; and 0.8 ≤ H1 / D1 ≤ 1.3. For example, the specific value of H1 / D1 can be, but is not limited to, 0.8, 0.9, 1.0, 1.1, 1.2, or 1.3; preferably, H1 / D1 = 1.0. By rationally designing the ratio of the length H1 of the blocking tube 153a and the inner tube diameter D1 of the second separation cover 152, under the suction action of the main fan 46 of the fan main module 40 of the convenient vacuum cleaner 1, the separation effect of large dust particles and small dust particles is improved, and the possibility of large dust particles passing over the tube wall of the blocking tube 153a and flowing from the cavity of the blocking tube 153a to the air outlet 152b of the second separation cover 152 and clogging the filter component 154 can be further effectively reduced.

[0053] like Figure 6 As shown, in the fourth embodiment, the inner diameter of the second separation cover 152 is D1 along a direction parallel to the plane where the air outlet 152b of the second separation cover 152 is located; the length of the air inlet 152a of the second separation cover 152 is H2 along a direction perpendicular to the plane where the air outlet 152b of the second separation cover 152 is located; and 0.2≤H2 / D1≤0.9. For example, the specific value of H2 / D1 can be, but is not limited to, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, or 0.9, etc.; preferably, H2 / D1=0.7. By reasonably designing the ratio of the length H2 of the air inlet 152a of the second separation cover body 152 and the inner tube diameter D1 of the second separation cover body 152, under the suction action of the main fan 46 of the fan main module 40 of the convenient vacuum cleaner 1, the separation effect of large dust particles and small dust particles is improved, and the possibility of large dust particles passing over the tube wall of the blocking tube 153a and flowing from the cavity of the blocking tube 153a to the air outlet 152b of the second separation cover body 152 and clogging the filter component 154 can be further effectively reduced.

[0054] like Figure 6As shown, in the fifth embodiment, the inner diameter of the second separation cover 152 is D1 along a direction parallel to the plane where the air outlet 152b of the second separation cover 152 is located; the length of the second separation cover 152 is H3 along a direction perpendicular to the plane where the air outlet 152b of the second separation cover 152 is located; and 3.5 ≤ H3 / D1 ≤ 4.0. For example, the specific value of H3 / D1 can be, but is not limited to, 3.5, 3.6, 3.7, 3.76, 3.8, 3.9, or 4.0, etc.; preferably, H3 / D1 = 3.76. By reasonably designing the ratio of the length H3 of the second separation cover body 152 and the inner tube diameter D1 of the second separation cover body 152, under the suction action of the main fan 46 of the fan main module 40 of the convenient vacuum cleaner 1, the separation effect of large dust particles and small dust particles is improved, and the possibility of large dust particles passing over the tube wall of the blocking tube 153a and flowing from the cavity of the blocking tube 153a to the air outlet 152b of the second separation cover body 152 and clogging the filter component 154 can be further effectively reduced.

[0055] Further, if Figure 6 As shown, the second separation cover 152 includes a first tube 1521 and a second tube 1522 connected to the first tube 1521. The first tube 1521 is closer to the air outlet 152b of the second separation cover 152 than the second tube 1522. From the side closest to the air outlet 152b of the second separation cover 152 to the side away from the air outlet 152b of the second separation cover 152, the inner diameter of the first tube 1521 is uniform throughout, while the inner diameter of the second tube 1522 gradually decreases.

[0056] Specifically, the specific design of the dimensions of the first tube body 1521 and the second tube body 1522 may include, but is not limited to, one or more of the following embodiments.

[0057] like Figure 6As shown, in the first embodiment, along a direction parallel to the plane where the air outlet 152b of the second separation cover 152 is located, the inner diameter of the first tube body 1521 is D1 (the second separation cover 152 includes the first tube body 1521, so the inner diameter D1 of the first tube body 1521 is also the inner diameter D1 of the second separation cover 152). Along a direction perpendicular to the plane where the air outlet 152b of the second separation cover 152 is located, the length of the first tube body 1521 is H4; and 1.2≤H4 / D1≤1.8. For example, the specific value of H4 / D1 can be, but is not limited to, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, or 1.8, etc.; preferably, H4 / D1=1.5. By reasonably designing the ratio of the length H4 of the first tube body 1521 and the inner tube diameter D1 of the first tube body 1521, under the suction action of the main fan 46 of the fan main module 40 of the convenient vacuum cleaner 1, the separation effect of large dust particles and small dust particles is improved, and the possibility of large dust particles passing over the tube wall of the blocking tube 153a and flowing from the cavity of the blocking tube 153a to the air outlet 152b of the second separation cover body 152 and clogging the filter component 154 can be further effectively reduced.

[0058] like Figure 6 As shown, in the second embodiment, the second tube 1522 has a cross section perpendicular to the plane of the air outlet 152b of the second separation cover 152; the cross section has two side edge lines close to the central axis of the second separation cover 152; the angle between the two side edge lines is α, and 10 degrees ≤ α ≤ 20 degrees. For example, the specific value of α can be, but is not limited to, 10 degrees, 11 degrees, 12 degrees, 13 degrees, 13.75 degrees, 14 degrees, 15 degrees, 16 degrees, 17 degrees, 18 degrees, 19 degrees, or 20 degrees, etc.; preferably, α = 13.75 degrees. By reasonably designing the value of the angle α, the main fan 46 of the fan main module 40 of the convenient vacuum cleaner 1 can form a larger suction force at the air inlet 152a of the first tube body 1521, ensuring that large particles of dust and small particles of dust can smoothly enter the cavity of the first tube body 1521 from the air inlet 152a of the first tube body 1521, so as to ensure the subsequent effective separation of large particles of dust and small particles of dust.

[0059] Furthermore, if Figure 3-Figure 4 As shown, considering that the number of the second separation cover bodies 152 can be one or more (more than two); when the number of the second separation cover bodies 152 is multiple, the multiple second separation cover bodies 152 are evenly spaced around the central axis of the first separation cover body 151; the number of the barrier members 153 is multiple, and the multiple barrier members 153 are arranged in a one-to-one correspondence with the multiple second separation cover bodies 152.

[0060] The plurality of second separate covers 152 may be, but are not limited to, formed into an integral structure by injection molding or 3D printing; the plurality of baffles 153 may also be, but are not limited to, formed into an integral structure by injection molding or 3D printing. The integral structure formed by the plurality of second separate covers 152 and the integral structure formed by the plurality of baffles 153 are separate entities, and the two may be detachably connected by, but are limited to, at least one of screwing, snapping, or plugging.

[0061] By designing multiple second separation covers 152 and multiple barriers 153 that are evenly spaced around the central axis of the first separation cover 151, the dust flowing into the cavity of the first separation cover 151 from the through holes 151a on the peripheral side of the first separation cover 151 can flow into the cavity of the second separation cover 152 from the air inlets 152a of different second separation covers 152, and each second separation cover 152 cooperates with the corresponding barrier 153 to effectively separate the large particles of dust and the small particles of dust flowing into its cavity, thereby effectively improving the separation efficiency of the cyclone separation structure 15.

[0062] Further, if Figure 3 、 Figure 7 and Figure 8 As shown, the filter assembly 154 includes a bracket 1541 and a filter 1542; the bracket 1541 has a plurality of ventilation holes 1541a equally spaced around the central axis of the first separation cover 151; each ventilation hole 1541a corresponds to an air outlet 152b of a second separation cover 152; the filter 1542 is arranged on the side of the bracket 1541 facing the air outlet 152b of the second separation cover 152, and the filter 1542 covers all the ventilation holes 1541a.

[0063] Among them, the bracket 1541 is a component in the filter assembly 154 used to evenly distribute the airflow formed by the suction force of the main fan 46 of the fan main module 40 of the convenient vacuum cleaner 1 into the cavities of the multiple second separation covers 152. The specific structure of the bracket 1541 is not limited here, and the designer can make a reasonable design based on actual needs; for example, the bracket 1541 can be, but not limited to, a ring-shaped plate structure. The specific connection method between the bracket 1541 and the baffle 153 / the second separation cover 152 / the first separation cover 151 is not limited here, and the designer can make a reasonable design based on actual needs; for example, the bracket 1541 can be, but not limited to, a detachable connection with the baffle 153 / the second separation cover 152 / the first separation cover 151 by screwing, snapping or plugging, so as to facilitate the replacement of the filter 1542.

[0064] The filter 1542 is a component in the filter assembly 154 used to filter small particles of dust, for example. The filter 1542 can be positioned on the air outlet side of the second separation cover 152 (that is, the side where the air outlet 152b of the second separation cover 152 is located) through the bracket 1541. In this way, the filter 1542 can be replaced by disassembling the bracket 1541, which is simple, convenient and quick to operate.

[0065] By designing bracket 1541, bracket 1541 can evenly distribute the airflow generated by the suction force of the main fan 46 of the fan main module 40 of the portable vacuum cleaner 1 within the cavities of the multiple second separation covers 152. This ensures that each second separation cover 152 cooperates with the corresponding barrier 153 to effectively separate large and small dust particles flowing into its cavity, thereby improving the separation efficiency of the cyclone separation structure 15; it also effectively reduces the possibility of noise caused by uneven airflow distribution. By designing filter 1542, filter 1542 can effectively separate small dust particles from the airflow, achieving the effect of purifying the airflow.

[0066] like Figure 7 and Figure 8 As shown, the filter assembly 154 also includes a plurality of partitions 1543, each of which is located between two adjacent ventilation holes 1541a and fixedly connected to the bracket 1541. The partition 1543 may be, but is not limited to, a vertical partition plate or a partition sleeve. The partition 1543 may be, but is not limited to, forming an integrated structure with the bracket 1541 by injection molding or 3D printing. By designing the partition 1543, the airflow flowing out of the air outlet 152b of the second separation cover 152 corresponding to the two adjacent partitions 1543 has a guiding effect, which can make the airflow flowing out of the air outlet 152b of the multiple second separation cover 152 flow evenly into the air inlet side of the main fan 46 of the fan main module 40 of the convenient vacuum cleaner 1.

[0067] like Figure 7 and Figure 8 As shown, the filter assembly 154 also includes a first sealing ring 1544, which is disposed on the side of the bracket 1541 facing the air outlet 152b of the second separation cover 152. The material of the first sealing ring 1544 can be, but is not limited to, elastic rubber or elastic silicone. The design of the first sealing ring 1544 effectively seals the outer periphery of the bracket 1541, thereby effectively reducing the possibility of air leakage.

[0068] like Figure 7 and Figure 8As shown, the filter assembly 154 also includes a second sealing ring 1545, which is disposed on the side of the bracket 1541 facing away from the air outlet 152b of the second separation cover 152. The material of the second sealing ring 1545 can be, but is not limited to, elastic rubber or elastic silicone. By designing the second sealing ring 1545, the second sealing ring 1545 can effectively seal the periphery of the bracket 1541, thereby effectively reducing the possibility of air leakage. It is worth mentioning that the second sealing ring 1545 cooperates with the first sealing ring 1544 to achieve a double effective seal on the periphery of the bracket 1541, thereby preventing air leakage around the periphery of the bracket 1541.

[0069] Please refer to Figure 3 As shown, in the second aspect, the present application proposes a dust bin module 10, which includes a bin body 11 and the above-mentioned cyclone separation structure 15; the bin body 11 has a dust collecting chamber for storing the object to be adsorbed, and a fluid inlet 11a connected to the dust collecting chamber; the first separation cover 151 is located in the dust collecting chamber and is used to connect with the bin body 11.

[0070] The bin body 11 includes a bin body 111 and a bottom cover 112. The bin body 111 has the aforementioned fluid inlet 11a. One side of the bottom cover 112 is hingedly connected to the bin body 111, and the other side of the bottom cover 112 can be snap-fitted to the bin body 111 to close or open the opening of the bin body 111. The bottom cover 112 and the bin body 111 together form the aforementioned dust collection chamber. The user can press the snap to open the bottom cover 112 to discharge garbage, such as paper scraps or dust, accumulated in the dust collection chamber.

[0072] Please refer to Figure 1-Figure 2 As shown, in a third aspect, the present application proposes a convenient vacuum cleaner 1 , which includes the above-mentioned dust bin module 10 .

[0073] Among them, the convenient vacuum cleaner 1 also includes a fan main body module 40, which can be detachably connected to the air outlet side of the dust bin module 10. The fan main body module 40 serves as the air source of the convenient vacuum cleaner 1. The fan main body module 40 includes a main shell 41 and a main fan 46. The main fan 46 is installed in the cavity of the main shell 41.

[0074] Based on the convenient vacuum cleaner 1 in the embodiment of the present application, it has the above-mentioned dust bin module 10, which can effectively separate garbage such as large-volume paper scraps and garbage such as small-volume dust in the adsorbent, and can also effectively separate large particles of dust and small particles of dust in the dust; it can also effectively separate small particles of dust from the wind flow to achieve the effect of purifying the wind flow.
