[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] Please refer to Figures 1-3As shown, in the first aspect, this application proposes a filter component 154, which enables multiple airflows to flow more evenly into the air inlet side of the main fan 46 of the fan body module 40 of the portable vacuum cleaner 1, which can effectively reduce the possibility of abnormal noise caused by uneven airflow distribution in the main fan 46 of the fan body module 40.

[0027] The filter assembly 154 is applied to the dust collection module 10; the dust collection module 10 includes a chamber 11; the chamber 11 has a dust collection chamber (not shown in the figure) for storing the object to be adsorbed, a fluid inlet 11a communicating with the dust collection chamber, and a fluid outlet 11c. The filter assembly 154 includes a support 1541, a filter screen 1542, and a separator 1543; the support 1541 is disposed corresponding to the fluid inlet 11a and is used to connect to the chamber 11, and the support 1541 has a ventilation hole 1541a for communicating with the dust collection chamber; the filter screen 1542 is disposed on the support 1541 and covers the ventilation hole 1541a; the separator 1543 is connected to the support 1541, and the separator 1543 is configured to divide the space of the support 1541 away from the fluid outlet 11c into multiple areas.

[0028] The following combination Figures 1-8 The specific structure of filter component 154 will be described in detail.

[0029] like Figures 1-3 As shown, the filter assembly 154 is applied to the dustbin module 10, which serves as a waste collection station for the portable vacuum cleaner 1. The dustbin module 10 includes a chamber body 11.

[0030] The housing 11 serves as the shell of the dust collection module 10. The specific material of the housing 11 is not limited here, and the designer can make a reasonable choice according to actual needs. For example, the material of the housing 11 can be, but is not limited to, plastic or aluminum alloy. The specific shape of the housing 11 is also not limited here, and the designer can make a reasonable design according to actual needs. For example, the cross-sectional shape of the housing 11 can be, but is not limited to, circular or rectangular.

[0031] The chamber 11 has a dust collection chamber, which is the space inside the chamber 11 used to store the object to be adsorbed; the object to be adsorbed can be, but is not limited to, dust or paper scraps and other garbage.

[0032] The chamber 11 also has a fluid inlet 11a that communicates with the dust collection chamber. The fluid inlet 11a is the opening of the chamber 11 for allowing adsorbents such as dust or paper scraps to flow into the dust collection chamber of the chamber 11. The specific shape of the fluid inlet 11a is not limited here, and designers can design it reasonably according to actual needs; for example, the cross-sectional shape of the fluid inlet 11a can be, but is not limited to, circular or rectangular.

[0033] The chamber 11 also has a fluid outlet 11c that communicates with the dust collection chamber. The fluid outlet 11c is the opening of the chamber 11 for allowing airflow to exit the dust collection chamber. The specific shape of the fluid outlet 11c is not limited here, and designers can design it reasonably according to actual needs; for example, the cross-sectional shape of the fluid outlet 11c can be, but is not limited to, circular or rectangular.

[0034] like Figures 3-5 As shown, the filter assembly 154 is a structural component of the dust collection module 10 for filtering, for example, small particulate dust. The filter assembly 154 includes a support 1541, a filter screen 1542, and a separator 1543.

[0035] The bracket 1541 serves as a carrier for the filter assembly 154, supporting components such as the filter screen 1542 and the separator 1543. The bracket 1541 is positioned corresponding to the fluid outlet 11c of the chamber 11, meaning that the orthographic projection of the bracket 1541 in the direction parallel to the central axis of the chamber 11 falls within the area enclosed by the fluid outlet 11c of the chamber 11.

[0036] The bracket 1541 is used to connect with the container body 11; the specific connection method between the bracket 1541 and the container body 11 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the bracket 1541 can be detachably connected to the container body 11 by at least one of the following methods: screw connection, snap connection or plug connection.

[0037] The support frame 1541 has a ventilation hole 1541a for communicating with the dust collection chamber of the hopper 11. The specific shape of the ventilation hole 1541a is not limited here; designers can design it reasonably according to actual needs. For example, the cross-section of the ventilation hole 1541a along the direction perpendicular to the central axis of the hopper 11 can be circular, rectangular, or fan-shaped. The specific number of ventilation holes 1541a is not limited here; designers can design it reasonably according to actual needs. For example, the number of ventilation holes 1541a can be one or more (two or more), and when there are multiple ventilation holes 1541a, the multiple ventilation holes 1541a can be arranged according to a preset arrangement.

[0038] like Figures 3-5 As shown, the filter screen 1542 serves as a filter element of the filter assembly 154 to effectively separate small dust particles from the airflow, thereby achieving the effect of purifying the airflow.

[0039] The filter screen 1542 is disposed on the bracket 1541. For example, when there is no connection between the filter screen 1542 and the bracket 1541, the filter screen 1542 can be stacked on one side of the bracket 1541; thus, the filter screen 1542 can be replaced by disassembling the bracket 1541, which is simple, convenient and quick. Alternatively, when there is a connection between the filter screen 1542 and the bracket 1541, the filter screen 1542 can be detachably connected to the bracket 1541 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection; this facilitates the replacement of the filter screen 1542.

[0040] like Figures 3-5 As shown, the separator 1543 is a component in the filter assembly 154 used to separate the airflow passing through the filter screen 1542 into multiple airflows. The specific form of the separator 1543 will be described in detail below.

[0041] The partition 1543 is connected to the bracket 1541. The specific connection method between the partition 1543 and the bracket 1541 is not limited here, and the designer can make a reasonable design according to the actual needs. For example, the partition 1543 can be detachably connected to the bracket 1541 by at least one of the following methods: screw connection, snap connection or plug connection. For another example, the partition 1543 can also be non-detachably connected to the bracket 1541 by adhesive bonding, but not limited to the following method.

[0042] The separator 1543 is configured to divide the space on the side of the bracket 1541 away from the fluid inlet 11a of the chamber 11 into multiple areas; thus, the airflow passing through the filter 1542 is divided into multiple airflows by the separator 1543, so that the multiple airflows flow into the air intake side of the main fan 46 of the fan main module 40 of the portable vacuum cleaner 1 more evenly, which can effectively reduce the possibility of abnormal noise from the main fan 46 of the fan main module 40 due to uneven airflow distribution.

[0043] Based on the filter assembly 154 in this embodiment, a support 1541 is designed to support the filter screen 1542 and the separator 1543. The filter screen 1542 effectively separates small dust particles from the airflow, achieving airflow purification. The separator 1543 divides the airflow passing through the filter screen 1542 into multiple streams, allowing these streams to flow more evenly into the air inlet side of the main fan 46 of the fan main module 40 of the portable vacuum cleaner 1. This effectively reduces the possibility of abnormal noise from the main fan 46 of the fan main module 40 due to uneven airflow distribution.

[0044] like Figures 4-5As shown, the partition 1543 includes a vertical partition plate 1543a; the vertical partition plate 1543a extends along a direction parallel to the central axis of the silo body 11, and a portion of the vertical partition plate 1543a extends into the ventilation hole 1541a of the support 1541 and is connected to the support 1541.

[0045] The specific connection method between the vertical partition 1543a and the bracket 1541 is not limited here, and the designer can make reasonable designs according to actual needs; for example, the vertical partition 1543a can be detachably connected to the bracket 1541 by means of screwing, snap-fitting or plugging; for another example, the vertical partition 1543a can be non-detachably connected to the bracket 1541 by means of adhesive bonding.

[0046] By designing a vertical partition plate 1543a, the vertical partition plate 1543a guides the airflow passing through the filter screen 1542 and divides it into multiple airflows. This allows the multiple airflows to flow more evenly into the air inlet side of the main fan 46 of the fan main module 40 of the portable vacuum cleaner 1, effectively reducing the possibility of abnormal noise from the main fan 46 of the fan main module 40 due to uneven airflow distribution.

[0047] like Figure 6 As shown, along the direction parallel to the central axis of the chamber 11, the height of the support 1541 is H1, and the height of the vertical partition plate 1543a is H2, and 1.2≤H2 / H1≤1.5. For example, the specific value of H2 / H1 can be, but is not limited to, 1.2, 1.3, 1.4, or 1.5, etc.; preferably, H2 / H1=1.3. By reasonably designing the ratio of the height H2 of the vertical partition plate 1543a to the height H1 of the support 1541, the space of the suction chamber can be maximized, so that the airflow passing through the filter 1542 can be effectively separated into multiple airflows after being guided by the vertical partition plate 1543a. This allows the multiple airflows to flow more evenly into the air inlet side of the main fan 46 of the fan main module 40 of the portable vacuum cleaner 1, which can effectively reduce the possibility of abnormal noise caused by uneven airflow distribution in the main fan 46 of the fan main module 40.

[0048] like Figure 6As shown, there are multiple ventilation holes 1541a, which are evenly spaced around the central axis of the hopper body 11; there are also multiple vertical partition plates 1543a, which are equally spaced around the central axis of the hopper body 11; each ventilation hole 1541a has a corresponding vertical partition plate 1543a on both sides in the direction of the central axis of the hopper body 11. For example, there are six ventilation holes 1541a, which are set approximately every 60 degrees in the direction of the central axis of the hopper body 11; there are also six vertical partition plates 1543a, with one vertical partition plate 1543a between two adjacent ventilation holes 1541a.

[0049] By designing multiple ventilation holes 1541a on the bracket 1541, the airflow passes through the filter screen 1542 and then through the multiple ventilation holes 1541a, where it is evenly divided into multiple airflows. Subsequently, the multiple airflows are further evenly separated by the guiding effect of the corresponding two adjacent vertical partition plates 1543a, allowing the multiple airflows to flow more evenly into the air intake side of the main fan 46 of the fan body module 40 of the portable vacuum cleaner 1. This can further effectively reduce the possibility of abnormal noise from the main fan 46 of the fan body module 40 due to uneven airflow distribution.

[0050] like Figure 7 As shown, each ventilation hole 1541a has a fan-shaped cross-section in a direction perpendicular to the central axis of the silo body 11, with the center of the fan-shaped cross-section falling on the central axis of the silo body 11. Along the direction perpendicular to the central axis of the silo body 11, the inner radius of the support 1541 is R, and the length of the vertical partition plate 1543a is L; and 1.5 ≤ L / R ≤ 2.0. For example, the specific value of L / R can be, but is not limited to, 1.5, 1.6, 1.7, 1.8, 1.9, or 2.0, etc.; preferably, L / R = 1.8. By rationally designing the ratio of the length L of the vertical partition plate 1543a to the inner radius R of the bracket 1541, the space of the suction chamber can be maximized, enabling the vertical partition plate 1543a to effectively separate the airflow passing through the filter screen 1542 to form multiple airflows. This allows the multiple airflows to flow more evenly into the air intake side of the main fan 46 of the fan main module 40 of the portable vacuum cleaner 1, effectively reducing the possibility of abnormal noise from the main fan 46 of the fan main module 40 due to uneven airflow distribution.

[0051] like Figure 5 As shown, the vertical partition plate 1543a and the bracket 1541 are integrally formed. The vertical partition plate 1543a can be, but is not limited to, formed into an integral structure with the bracket 1541 through injection molding or 3D printing. This effectively reduces the processing difficulty between the vertical partition plate 1543a and the bracket 1541.

[0052] Of course, in other embodiments, the separator 1543 may also include a separator sleeve, the cylindrical axis of which is parallel to the central axis of the chamber 11. The separator sleeve is located on the side of the support 1541 facing away from the fluid outlet 11c of the chamber 11 and is provided corresponding to the ventilation hole 1541a. The separator sleeve is connected to the support 1541.

[0053] Other structural designs for the filter assembly 154 may be, but are not limited to, one or more of the following embodiments.

[0054] like Figures 4-5 As shown, the filter assembly 154 also includes a first sealing ring 1544, which is disposed on the side of the support 1541 facing the fluid outlet 11c of the chamber 11. The material of the first sealing ring 1544 can be, but is not limited to, elastic rubber or elastic silicone. By designing the first sealing ring 1544, it can effectively seal the outer periphery of the support 1541, thereby effectively reducing the possibility of air leakage.

[0055] like Figures 4-5 As shown, the filter assembly 154 also includes a second sealing ring 1545, which is disposed on the side of the support 1541 facing away from the fluid outlet 11c of the chamber 11. 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, it can effectively seal the outer periphery of the support 1541, thereby effectively reducing the possibility of air leakage. It is worth mentioning that the second sealing ring 1545, together with the first sealing ring 1544, provides a double effective seal for the outer periphery of the support 1541, thus effectively preventing air leakage around the outer periphery of the support 1541.

[0056] Please refer to Figures 1-3 As shown, in a second aspect, this application proposes a dust collection module 10, which includes a collection body 11 and the aforementioned filter assembly 154; the collection body 11 has a dust collection chamber for storing the object to be adsorbed, a fluid inlet 11a communicating with the dust collection chamber, and a fluid outlet 11c; the bracket 1541 is provided corresponding to the fluid outlet 11c of the collection body 11 and is connected to the collection body 11.

[0057] Based on the dust collection module 10 in this embodiment, which has the above-mentioned filter component 154, the filter screen 1542 can effectively separate small dust particles from the airflow to achieve the effect of purifying the airflow; the separator 1543 can divide the airflow passing through the filter screen 1542 into multiple airflows, so that the multiple airflows flow into the air inlet side of the main fan 46 of the fan body module 40 of the portable vacuum cleaner 1 more evenly, which can effectively reduce the possibility of abnormal noise caused by uneven airflow distribution of the main fan 46 of the fan body module 40.

[0059] Based on the portable vacuum cleaner 1 in this application embodiment, having the above-mentioned dust bin module 10, it can divide the airflow passing through the filter screen 1542 into multiple airflows, so that the multiple airflows flow into the air inlet side of the main fan 46 of the fan body module 40 of the portable vacuum cleaner 1 more evenly, which can effectively reduce the possibility of abnormal noise caused by uneven airflow distribution of the main fan 46 of the fan body module 40.

[0060] like Figure 2 , Figure 3 and Figure 8 As shown, the main fan module 40 includes a main housing 41, a main fan 46, and a fan shroud 47; the main housing 41 is connected to the chamber 11; the main fan 46 is located in the chamber of the main housing 41 and is connected to the main housing 41; the fan shroud 47 is disposed on the air inlet side of the main fan 46 and is connected to the main housing 41; one end of the separator 1543 away from the fluid outlet 11c of the chamber 11 extends to abut against the air inlet of the fan shroud 47.

[0061] The main housing 41 serves as the outer shell of the main fan module 40, supporting components such as the main fan 46. The specific structure of the main housing 41 is not limited here; designers can design it appropriately according to actual needs. The main housing 41 is connected to the hopper 11. The specific connection method between the main housing 41 and the hopper 11 is not limited here; designers can design it according to actual needs. For example, the main housing 41 can be detachably connected to the hopper 11 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection.

[0062] The main fan 46 serves as the air source for the main fan module 40, generating suction. The specific model of the main fan 46 is not limited here; designers can choose appropriately based on actual needs. The main fan 46 is connected to the main housing 41. The specific connection method between the main fan 46 and the main housing 41 is not limited here; designers can design appropriately based on actual needs. For example, the main fan 46 can be detachably connected to the main housing 41 via, but is not limited to, screw connection, snap-fit ​​connection, or plug-in connection.

[0063] The shroud 47 serves as the outer shell of the main fan module 40. The specific structure of the shroud 47 is not limited here; designers can design it reasonably according to actual needs.

For example, the shroud 47 can be detachably connected to the main housing 41 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection.

[0064] The main housing 41 is designed to support the main fan 46 and the hood 47.

The hood 47 is designed to act as a protective shell for the main fan 46. By extending the end of the separator 1543 away from the fluid outlet 11c of the chamber 11 to abut against the air inlet of the hood 47, the airflow passing through the filter 1542 can be effectively separated into multiple airflows after being guided by the separator 1543. Under the guidance of the separator 1543, the multiple airflows can be directly guided to the air inlet of the hood 47, so that the multiple airflows can flow into the air inlet side of the main fan 46 of the fan main module 40 of the portable vacuum cleaner 1 more evenly, which can effectively reduce the possibility of abnormal noise caused by uneven airflow distribution of the main fan 46 of the fan main module 40.
