The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, the present invention provides a vacuum cleaner 10. The vacuum cleaner 10 includes a filter device 11, an exhaust device 13, a power supply device 15, and a grip portion 17. The power supply device 15 drives the exhaust device 13 to work so as to form negative suction pressure in the filter device 11, so that external air flow enters the filter device 11. The filter device 11 is used for filtering dust and impurities in the air flow. The grip portion 17 is for facilitating gripping by a user. In some embodiments, the holding portion 17 is a hollow structure, a controller is disposed in the holding portion 17, the controller is electrically connected to the air exhausting device 13 and the power supply device 15, and a control button 170 is disposed on the outer periphery of the holding portion 17. When the vacuum cleaner 10 is in operation, the controller controls the power supply device 15 to drive the exhaust device 13 to operate by pressing the control button 170. After the cleaning operation is completed, the control button 170 is pressed again, and the cleaner 10 stops operating.

The exhaust device 13 and the power supply device 15 are disposed opposite to each other at an interval at opposite ends of the filter device 11, and the exhaust device 13 and the filter device 11 can exchange air flows. The grip portion 17 is connected between the exhaust device 13 and the power supply device 15. Both ends of the axis of the grip portion 17 pass through the power supply device 15 and the exhaust device 13, respectively, with the axis of the grip portion 17 as a reference.

Specifically, in the vacuum cleaner 10, the exhaust device 13 and the power supply device 15 are the main weight components of the vacuum cleaner 10, and the holding portion 17 is connected between the exhaust device 13 and the power supply device 15, so that the weight of the vacuum cleaner 10 can be uniformly distributed at two ends of the holding portion 17, and the center of gravity of the vacuum cleaner 10 is closer to the holding portion 17. The two ends of the axis of the holding portion 17 pass through the power supply device 15 and the exhaust device 13, respectively. Therefore, the weight of the vacuum cleaner 10 can be more evenly distributed on the two sides of the holding portion 17, so that the gravity center of the vacuum cleaner 10 is closer to the holding portion 17. Therefore, the cleaner 10 can be held more easily and with less effort.

When the holding portion 17 is connected between the air exhaust device 13 and the power supply device 15, in some embodiments, the holding portion 17 is disposed obliquely relative to the air exhaust device 13 and the power supply device 15, and a distance from an end of the holding portion 17 connected to the power supply device 15 to the filter device 11 is greater than a distance from an end of the holding portion 17 connected to the air exhaust device 13 to the filter device 11. That is, the end of the grip portion 17 connected to the air discharging device 13 is closer to the filter device 11 than the end of the grip portion 17 connected to the power supply device 15. The design accords with the setting of human engineering, can be convenient for a user to hold, and saves more labor when holding.

In other embodiments, the holding portion 17 may be disposed perpendicular to the air discharging device 13 and the power supply device 15.

Referring to fig. 2 and 3, the filter device 11 includes a housing 110 and a filter assembly 112 accommodated in the housing 110. Specifically, housing 110 has a housing interior 1101, and filter assembly 112 is housed within housing interior 1101. The exhaust device 13 includes an exhaust housing 130 having an exhaust cavity 1301, an exhaust member 132, and a power module 134 for electrically driving the exhaust member 132, wherein the exhaust member 132 and the power module 134 are accommodated in the exhaust cavity 1301. The power supply device 15 includes a power supply housing 150 having a power supply cavity 152 and a power supply assembly 154 housed within the power supply cavity 152. The exhaust casing 130 and the power supply casing 150 are respectively connected to two opposite ends of the casing 110 and are located on the same side of the casing 110, so as to form a casing of the whole vacuum cleaner 10. Specifically, the case 110, the exhaust case 130, and the power supply case 150 may be integrally formed or separately formed.

In the vacuum cleaner 10, the power supply housing 150 is generally disposed at the bottom of the overall vacuum cleaner 10, and the exhaust housing 130 is spaced apart from the power supply housing 150 and is disposed at the top of the overall vacuum cleaner 10. The housing 110 is located on the left side of the cleaner 10 and the grip 17 is generally located on the right side of the cleaner 10 in accordance with the principles of a user operating with a generally right hand.

The outer wall of the housing 110 defines an air inlet 1102 communicated with the housing cavity 1101, and the air inlet pipe 114 is coupled to the air inlet 1102 and communicated with the air inlet 1102 to form an air inlet channel 1141. The exhaust cavity 1301 of the exhaust casing 130 is communicated with the casing inner cavity 1101 of the casing 110, and the exhaust casing 130 is provided with an exhaust port 1303 communicated with the exhaust cavity 1301. The power supply cavity 152 is isolated and independent from the dust removal cavity and the exhaust cavity 1301. Therefore, the power supply assembly 154 accommodated in the power supply cavity 152 can be isolated from external moisture and dust, so as to maintain the normal operation of the power supply assembly 154. In addition, when the power supply assembly 154 is disposed in the power supply cavity 152, the weight of the entire power supply device 15 can be made large. Therefore, the power supply device 15 can be used as a supporting body of the entire cleaner 10. When the cleaner 10 is not in use, the operation power supply device 15 is in contact with a mounting surface (e.g., the floor, a table top, etc.), so that the entire cleaner 10 can be stably mounted to the mounting surface.

In some embodiments, the exhaust casing 130 and the power supply casing 150 are disposed in parallel, and both the exhaust casing 130 and the power supply casing 150 are disposed perpendicular to the housing 110, so that the overall appearance of the vacuum cleaner 10 is more regular and more beautiful. In this embodiment, the housing 110 is vertically disposed, and the exhaust housing 130 and the power supply housing 150 are horizontally disposed. (the horizontal and vertical directions mentioned in the present invention all refer to the horizontal and vertical directions of the vacuum cleaner 10 shown in fig. 1 as the reference standard, i.e. the state of the vacuum cleaner 10 when normally placed on the horizontal plane).

In other embodiments, the exhaust housing 110 and the power supply housing 150 may be disposed obliquely.

The power module 134 is electrically connected to the power supply module 154, and the power module 134 forms a negative pressure suction force in the housing inner cavity 1101 and the exhaust cavity 1301 under the driving of the power supply module 154, so that air in the external environment forms an air flow to enter the housing inner cavity 1101, and flows into the exhaust cavity 1301 after passing through the filter module 112 from the housing inner cavity 1101. The filter assembly 112 is used for filtering the airflow with dust and impurities, and the filtered dust and impurities are collected in the housing cavity 1101. The exhaust member 132 is used to re-filter the airflow before it is exhausted from the exhaust opening 1303 and to re-exhaust the filtered clean airflow into the external environment.

The power assembly 134 is located between the filter assembly 112 and the exhaust 132.

I.e., the power module 134 is closer to the filter module 112 than the exhaust 132. Accordingly, the airflow filtered by the filter assembly 112 has a shorter path to the power assembly 134. The shorter path results in less wind loss and less momentum decay in the air stream as it flows to power assembly 134. Further, the airflow can still flow to the exhaust member 132 at a relatively high speed, and is filtered by the exhaust member 132 and then exhausted from the exhaust opening 1303 to the external environment. The air flow has a fast flowing speed, which can accelerate the exchange speed between the air flow in the dust collector 10 and the outside, thereby effectively improving the working efficiency of the whole dust collector 10.

Further, the air inlet end of the power assembly 134 is coupled to the air outlet end of the filter assembly 112.

The air inlet end of the power assembly 134 is coupled to the air outlet end of the filter assembly 112, so that the airflow path between the filter assembly 112 and the power assembly 134 can be further shortened, the air loss of the airflow is smaller, and the working efficiency of the vacuum cleaner 10 can be further improved. Specifically, the air inlet end of the power assembly 134 is coupled to the air outlet end of the filter assembly 112, and it can be understood that the power assembly 134 is located outside the filter assembly 112, and the air inlet end surface of the power assembly 134 abuts against the air outlet end surface of the filter assembly 112, so that the power assembly 134 and the filter assembly 112 are only overlapped at the end surface of the air inlet end of the power assembly 134 and the air outlet end surface of the filter assembly 112. Or, the air inlet end of the power assembly 134 and the air outlet end of the filter assembly 112 may be sleeved, so that the power assembly 134 and the filter assembly 112 have more overlapped portions. Specifically, the air inlet end of the power assembly 134 is sleeved with the air outlet end of the filter assembly 112, which can be understood as the air inlet end of the power assembly 134 extends into the filter assembly 112 through the air outlet end port of the filter assembly 112, or the air outlet end of the filter assembly 112 extends into the power assembly 134 through the air inlet end port of the power assembly 134.

Furthermore, the air outlet end of the filter assembly 112 is sleeved with the air inlet end of the power assembly 134.

Therefore, the airflow flowing out of the air outlet end of the filter assembly 112 can directly enter the power assembly 134, so that the path of the airflow between the filter assembly 112 and the power assembly 134 is shortest, the airflow has the smallest wind loss, and the whole vacuum cleaner 10 has higher working efficiency.

The axis (b-b) of the power assembly 134 passes through the air outlet end of the filter assembly 112 and the air inlet end of the power assembly 134, the axis (a-a) of the filter assembly 112 and the axis of the power assembly 134 form an included angle, and the included angle (angle beta) is less than or equal to 90 degrees.

Specifically, the air intake direction (as indicated by arrow c in FIG. 2) at the air intake end of filter assembly 112 is perpendicular to the direction (Y-direction) of extension of the axis (a-a) of filter assembly 112. Under the action of the power module 134, the outlet direction (shown by arrow d in fig. 2) of the outlet end of the filter module 112 and the inlet direction (shown by arrow d in fig. 2) of the inlet end of the power module 134 are the same as the extending direction (X direction) of the axis (b-b) of the power module 134. The direction of the airflow within filter element 112 between the inlet end and the outlet end (as indicated by arrow e in fig. 2) is the same as the direction (Y direction) along which the axis (a-a) of filter element 112 extends. The included angle between the axis (a-a) of the filter element 112 and the axis (b-b) of the power element 134 can be understood as the included angle ([ beta ]) between the airflow direction of the filter element 112 at the inlet end and the outlet direction of the filter element 112 at the outlet end, or can be understood as the included angle ([ beta ]) between the airflow direction of the filter element 112 at the inlet end and the outlet end and the inlet direction of the power element 134 at the inlet end. By setting the axis (a-a) of the filtering component 112 and the axis of the power component 134(b-b) to be an included angle (° β), and the included angle (° β) is less than or equal to 90 degrees, the airflow can enter the air inlet end of the power component 134 only by rotating a small angle after flowing through the filtering component 112, so that the turning windage of the airflow can be effectively reduced, the airflow still keeps a fast flow speed, and the working efficiency of the dust collector 10 is improved.

The power module 134 and the exhaust member 132 are spaced apart from each other in the axial direction of the power module 134.

Generally, the power assembly 134 generates sound waves during operation, and the sound waves are propagated by the flow of the airflow. In the present application, by disposing the power module 134 and the exhaust member 132 at a distance, the propagation path of the sound wave in the exhaust cavity 1301 is increased, and the contact frequency of the sound wave with the inner wall of the exhaust housing 130 is increased. The sound waves continuously collide with the inner wall of the exhaust cavity 1301, so that the momentum of the sound waves is greatly attenuated, and the decibel number of the sound waves is weakened. Further, the sound wave noise discharged from the air outlet 1303 is small, and the user experience of the vacuum cleaner 10 is improved accordingly.

It should be noted that, in other embodiments, the power module 134 and the exhaust member 132 may also be abutted.

Referring again to fig. 2, the filter assembly 112 includes a dust-removing part 1121, a separating part 1123 and a filter member 1125 coupled to the housing cavity 1101. The dust removing part 1121, the separating part 1123 and the filtering part 1125 are sequentially arranged along the axial direction of the filter assembly 112 from the bottom to the top of the inner cavity 1101 of the housing, and the separating part 1123 is communicated between the dust removing part 1121 and the filtering part 1125. The external air flow passes through the air inlet channel 1141, the dust removing member 1121 and the separating member 1123 in sequence, and the air flow separated by the separating member 1123 enters the filter 1125 and flows into the power module 134 from the air outlet end of the filter module 11. The dust removing part 1121, the separating part 1123 and the filtering part 1125 can perform gas-dust separation on the gas.

Referring to fig. 4, 5 and 9, the dust-removing part 1121 is a cylindrical filter screen. The dedusting piece 1121 is hollow to form a dedusting cavity 11210, the side wall of the dedusting piece 1121 is provided with a dedusting hole 11212, the separating piece 1123 is provided with a separating channel 11230, and the dedusting hole 11212, the dedusting cavity 11210 and the separating channel 11230 are sequentially communicated. Specifically, the dust removing cavity 11210 is a space surrounded by the filter screen, and the space is a part of the inner cavity 1101 of the housing. The filtering member 1125 includes a filtering body 11250 and at least two wind-blocking walls 11252 disposed at the periphery of the filtering body 11250, the filtering body 11250 is hollow to form a collecting cavity 11253, the at least two wind-blocking walls 11252 are disposed along the circumference of the filtering body 11250, and the periphery of the filtering body 11250 is separated to form an air inlet region 11254 and an air outlet region 11255, which are independent of each other. The air flow is once filtered by the air inlet region 11254 and then secondarily filtered by the air outlet region 11255, and is exhausted by the exhaust device 13.

The specific flow paths for the gas streams into and out of housing cavity 1101 are explained by the specific description below. Referring to fig. 3 and fig. 6, the airflow entering the housing cavity 1101 from the air inlet channel 1141 passes through the dust removing hole 11212, the dust removing cavity 11210 and the separating channel 11230 in sequence under the action of the power assembly 134. Then, the airflow generated by the separation channel 11230 of the separating piece 1123 enters the collecting cavity 11253 from the air inlet region 11254, and then flows into the air inlet end of the power assembly 134 through the air outlet region 11255. When the airflow passes through the dust removing holes 11212, dust and impurities with larger particle sizes are separated from the airflow and collected at the bottom of the inner cavity 1101 of the housing. In turn, the airflow flows from within the dust removal cavity 11210 into the separation channel 11230 in a direction toward the top of the housing cavity 1101. In particular, the separating member 1123 is a cyclone separator and the separating channel 11230 is defined by the inner wall of a cone-like structure. An air inlet 11232 is formed in the side wall of the conical structure, and the air flow flows into the separation channel 11230 from the air inlet 11232, and separates the air flow and dust and impurities with small particle size in the separation channel 11230.

Referring to fig. 7, the filter assembly 112 further includes a dust collecting member 1127, and the dust collecting member 1127 is disposed through the dust removing cavity 11210. The dust collection piece 1127 abuts against the bottom of the housing cavity 1101 and the end of the tapered structure facing the bottom of the housing cavity 1101, respectively, to support the separating piece 1123 and position itself. One end of the dust removing piece 1121 facing the separating piece 1123 is provided with a dust collecting hole 11270, a dust collecting cavity 11272 is formed inside the dust collecting piece 1127, and the dust collecting hole 11270 is aligned with and communicated with the opening of the separating channel 11230 facing the bottom of the inner cavity 1101 of the housing. Therefore, dust and foreign substances having a small particle size separated from the separating passage 11230 can be collected in the dust collecting chamber 11272 from the dust collecting hole 11270. The airflow separated by the separating channel 11230 continues to flow, sequentially flows through the air inlet region 11254, the collecting cavity 11253 and the air outlet region 11255, then flows into the air inlet end of the power assembly 134, passes through the air exhaust member 132, and is exhausted from the air outlet 1303. The air inlet region 11254 and the air outlet region 11255 perform primary and secondary filtering on the airflow, respectively, so that the dust and impurities separated at the air inlet region 11254 can fall onto the separating member 1123, or be collected at the bottom of the internal cavity 1101 of the housing, etc. Dust and debris separated in the outlet region may collect in the collection chamber 11253. Compared to the conventional filter 1125, the filter 1125 of the present application can filter the airflow twice, so that the dust collector 10 and the filter 11 thereof have better air-dust separation effect. The wind-blocking wall 11252 prevents the air flowing through the air inlet region 11254 and the air outlet region 11255 from flowing by, so that the air flows through the air outlet region 11255 after passing through the air inlet region 11254 when passing through the filter 1125, thereby ensuring that the vacuum cleaner 10 and the filter 11 have a better air-dust separation effect.

Referring to fig. 8 and 9, the casing 110 includes an air guiding casing 110, the filtering device 11 includes an air guiding pipe 116, the air guiding casing 110 is in an open annular structure and has an opening formed at a tail end, and the air guiding pipe 116 is hermetically coupled to the opening and correspondingly communicated with the air outlet area 11255 on the filtering main body 11250. The power assembly 134 of the exhaust device 13 is coupled to an end of the air duct 116 away from the air outlet region 11255. The wind guide housing 110 is disposed around the filter main body 11250 of the wind inlet region 11254, and a wind guide cavity 11041 is formed therebetween. The wind guide shell 110 is provided with wind guide holes 11043, the filter main body 11250 located in the wind inlet region 11254 is provided with primary filter holes 11256, and the wind guide holes 11043, the wind guide cavity 11041 and the primary filter holes 11256 are communicated together to form a wind inlet channel. The filter main body 11250 located in the air outlet region 11255 is opened with a secondary filter hole 11257, and the secondary filter hole 11257 and the air guide pipe 116 are connected together to form an air outlet channel.

Specifically, the housing 110 further includes a main housing 1103, in some embodiments, a housing inner cavity 1101 is formed in the main housing 1103, and the air guiding housing 110 is coupled in the main housing 1103 and divides the housing inner cavity 1101 into spaces forming the flow guiding cavity 11041, the separation cavity 1103 and the filter 1125. In other embodiments, the main housing 1103 may also be butted with the wind guiding housing 110 to form a whole housing 110 structure, a separation cavity 1103 is formed in the main housing 1103, the wind guiding housing 110 is a double-layer structure, and a space between the wind guiding cavity 11041 and the filter 1125 is formed in the wind guiding housing 110. The flow guide chamber 11041, the separation chamber 1103 and the space where the filter 1125 is disposed are collectively configured to form a housing interior 1101. The dust removing part 1121 and the separating part 1123 are located in the separating cavity 1103, and the separating channel 11230 on the separating part 1123 is communicated with the air guiding hole 11043 away from the opening of the dust collecting part 1127. The airflow separated from the separation channel 11230 sequentially passes through the air guide hole 11043, the flow guide cavity 11041, the primary filter hole 11256, the collection cavity 11253, the secondary filter hole 11257 and the air guide pipe 116 and enters the air inlet end of the power assembly 134. Specifically, an end of the air guiding pipe 116 away from the secondary filter hole 11257 is an air outlet end of the filter assembly 112.

By arranging the wind guide shell 110, on one hand, the wind guide shell 110 and the wind inlet region 11254 together form a wind inlet channel which can guide the airflow, so as to ensure that the airflow flowing out of the separating element 1123 can be guided to the wind inlet region 11254 under the action of the wind inlet channel. The provision of the air inlet channel allows the air to enter the air inlet region 11254 in a concentrated manner, as compared to the air flow which is diffused around the housing cavity 1101, thereby facilitating the operation of the vacuum cleaner 10. On the other hand, when the airflow passes through the primary filtering holes 11256 of the filtering main body 11250, the separated dust and impurities with smaller particle size can be collected in the flow guiding chamber 11041, so as to prevent the dust and impurities from diffusing and affecting the dust removing effect of the vacuum cleaner 10.

Further, the pore diameter of the primary filter hole 11256 is larger than that of the secondary filter hole 11257.

Compared with the primary filter hole 11256 and the secondary filter hole 11257, the size of the primary filter hole 11256 is larger than that of the secondary filter hole 11257, so that the filter 1125 can filter dust and impurities with different particle sizes, and the dust collector 10 has a better air-dust separation effect.

The wind guide housing 110 is provided with a mounting hole 11044, the filter 1125 is detachably assembled in the wind guide housing 110 through the mounting hole 11044, and the collection chamber 11253 is communicated with the flow guide chamber 11041.

Therefore, the attachment and detachment of the filter 1125 can be facilitated. When the collecting chamber 11253 is full of dust and impurities, the filter 1125 can be removed from the vacuum cleaner 10 through the mounting hole 11044, cleaned and then re-placed in the air guide housing 110 for use, so as to prevent the dust from blocking the primary filter hole 11256 and the secondary filter hole 11257 and causing poor filtering effect of the filter 1125. Specifically, the mounting holes 11044 may be opened to a side wall, a top wall, or a bottom wall, etc., of the air guide housing 110. In this embodiment, mounting hole 11044 is opened in the top wall of wind guide housing 110, one end of filter 1125 is provided with an opening communicating with collecting chamber 11253, and the opening of filter 1125 is aligned with mounting hole 11044, so that when filter 1125 is installed in wind guide housing 110, dust and impurities in filter 1125 can be collected by gravity in the bottom of collecting chamber 11253.

To facilitate the loading and unloading of the filter 1125, a handle 11258 may be attached to the open edge of the filter 1125 to facilitate the user to grasp the handle 1125 and manipulate the filter 1125 for installation or removal.

It should be noted that, if the casing 110 is formed by coupling the wind guiding casing 110 to the main casing 1103, an assembly opening may be formed at the top end of the main casing 1103, and the cover covers the assembly opening. When the cover is removed, the dust removing part 1121, the dust collecting part 1127, the separating part 1123, the air guide casing 110, the filter part 1125, and the air guide pipe 116 can be removed or mounted from the mounting opening, so that the convenience of mounting the cleaner 10 can be improved. If the main housing 1103 and the wind guide housing 110 are butted to form the whole housing 110, a cover can be disposed at the mounting hole 11044, the filtering member 1125 can be assembled by opening the cover, and the cover can prevent the dust and impurities collected in the collecting cavity 11253 from being blown away to the external environment, so that the vacuum cleaner 10 is easy to assemble and has a better dust collecting effect.

Further, the mounting hole 11044 is a stepped hole, and the outer edge of the filter body 11250 is formed with a overlapping edge 11259, and the overlapping edge 11259 is overlapped on the hole wall of the stepped hole.

Specifically, the overlapping edge 11259 may overlap the wall of the hole under the influence of gravity, and first, may support and secure the entire filter 1125, making installation of the filter 1125 simpler and more stable. Therefore, the filter 1125 can be prevented from swaying relative to the housing 110, which may cause the diversion chamber 11041 not to align with the air inlet region 11254, and the air outlet region 11255 not to align with the air duct, which may affect the filtering effect of the filter 1125. Second, the provision of the overlapping edge 11259 also facilitates removal of the filter 1125.

Furthermore, the casing 110 includes a plurality of ribs, the air guiding casing 110 includes a bottom wall 11045, a side wall 11046 formed by extending the outer edge of the bottom wall 11045 in the same direction, and a top wall 11047 opposite to the bottom wall 11045, each rib is fitted between the top wall 11047 and the bottom wall 11045 along the axial direction of the filter 1125, and the plurality of ribs are arranged at intervals along the circumference of the filter 1125, and the filter 1125 is detachably fitted in the space surrounded by the plurality of ribs.

Specifically, the bottom wall 11045 is provided with an air guiding hole 11043, the mounting hole 11044 is provided on the top wall 11047, the bottom wall 11045, the top wall 11047 and the side wall 11046 are commonly surrounded to form a flow guiding cavity 11041, and the air guiding hole 11043 is communicated between the separating channel 11230 of the separating piece 1123 and the flow guiding cavity 11041. Therefore, the airflow in the air guiding hole 11043 can enter the guiding cavity 11041 along the driving direction of the power assembly 134 under the action of the air guiding hole 11043. In some embodiments, the projections of the top wall 11047 and the side wall 11046 on the bottom wall 11045 may partially cover the bottom wall 11045. In this embodiment, when the filter 1125 is installed in the air guide housing 110, the surface of the filter 1125 facing away from the mounting hole 11044 may be attached to the bottom wall 11045, so that the filter 1125 may be stably supported on the bottom wall 11045. Alternatively, in other embodiments, the top wall 11047 and the projection of the side wall 11046 onto the bottom wall 11045 may completely cover the bottom wall 11045. In this embodiment, a position-avoiding hole is formed in the bottom wall 11045 at a position opposite to the mounting hole 11044, and when the filter 1125 is mounted in the air guide housing 110, the filter 1125 is inserted into the position-avoiding hole and the mounting hole 11044.

And through setting up many ribs 1104, many ribs 1104 have limiting displacement to the installation of filtering piece 1125, filter piece 1125 can be fixed in the space that rib 1104 encloses to close steadily to prevent that filtering piece 1125 from rocking and leading to that water conservancy diversion chamber 11041 can't aim at with air inlet region 11254 in the course of the work, and air outlet region 11255 can't aim at with guide duct 116 and cause the relatively poor filtering effect of filtering piece 1125. Specifically, the space here is only the mounting area of the filter 1125, which is not part of the flow guide cavity 11041. The space, together with the flow directing chamber 11041 and the separation chamber 1103, forms a housing interior 1101.

Further, a plurality of ribs 1104 are arranged outside the air inlet region 11254 at intervals along the circumferential direction of the filtering member 1125, each rib 1104 is attached to the outer surface of the filtering main body 11250 of the air inlet region 11254, and each two adjacent ribs 1104 separate the corresponding air inlet region 11254 to form a sub air inlet region 11254.

Specifically, each adjacent two ribs 1104 may guide the airflow in the flow guide cavity 11041, so that the airflow in the flow guide cavity 11041 corresponding to each sub air inlet region 11254 may flow from the corresponding sub air inlet region 11254 into the collecting cavity 11253. Consequently, the air current is more orderly and comparatively be when passing through the regional 11254 of air inlet, and this not only makes the regional 11254 of air inlet that passes through that the air current can be faster to in the work efficiency who improves dust catcher 10, moreover, the regional 11254 of every sub-air inlet all can filter the air current, still can promote dust catcher 10's filter effect.
