[0003] Existing vacuum cleaners mainly include components such as a suction pipe, a shell, a dust cup, a filter assembly, an airflow generating assembly, a handle, and a power supply assembly. When in use, first, the airflow generating assembly generates a negative pressure airflow, and the dirt on the ground enters the dust cup along the suction path along the negative pressure airflow, and is guided to the position of the filter assembly. Then, the dirt flow will rotate around the filter assembly along the dirt filtering path, thereby separating the airflow from the dirt. Finally, the larger particles of dirt separated by the filter assembly are guided to the first dust collecting area of ​​the dust cup through the dust outlet, and the separated airflow is discharged to the outside of the vacuum cleaner through the exhaust hole of the shell.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0045] Embodiment 1

[0046] like Figures 1 to 13 As shown, this embodiment provides a dust collecting assembly 1, which mainly includes a dust cup 100, a drainage part 101, a filter assembly 2 and a dust collecting area.

[0047] The dust cup 100 is a cup body with an open rear end surface and a hollow interior structure. It includes a fluid inlet 1001 opened on the front end surface of the dust cup 100, a movable cover 1002 forming a part of the end surface of the dust cup 100, and an arc-shaped guide plate 1003 disposed inside the dust cup 100, wherein the end of the arc-shaped guide plate 1003 forms a dust outlet 10031;

[0048] The drainage portion 101 is removably disposed inside the dust cup 100, and includes an inlet end 1011 communicating with the fluid inlet 1001, an outlet end 1013 facing the arc-shaped guide plate 1003, and a spiral channel 1012 between the inlet end 1011 and the outlet end 1013, wherein the spiral channel 1012 and the arc-shaped guide plate 1003 form a spiral guide axis;

[0049] The filter assembly 2 is removably disposed inside the dust cup 100, and includes a dirt filter axis AA that is butted against the end of the spiral guide axis, wherein the front end of the filter assembly 2 abuts against the end of the drainage portion 101;

[0050] The dust collecting area includes a first dust collecting area 1004 and a second dust collecting area 1005 arranged inside the dust cup 100, wherein the dust outlet 10031 is connected to the first dust collecting area 1004, and the dust outlet 10031 and the first dust collecting area 1004 are both located directly below the filter assembly 2.

[0051] In this embodiment, the arc guide plate 1003 is composed of an arc plate 10032 and an inclined plate 10033. The inclined plate 10033, the front end plate 1006 and a part of the movable cover body 1002 form a second dust collecting area 1005. The arc plate 10032, the inclined plate 10033, the bottom wall of the dust cup 100 and another part of the movable cover body 1002 form a first dust collecting area 1004.

[0052] Specifically, the arc-shaped guide plate 1003 forms the top wall of the first dust collecting area 1004 and the bottom wall of the second dust collecting area 1005 , respectively. Such a design can simplify the internal structure of the dust cup 100 .

[0053] Preferably, the shape of the arc guide plate 1003 is a concave arc structure, and the left and right sides of the arc guide plate 1003 are respectively connected to the inner side of the left wall and the inner side of the right wall of the dust cup 100. This design can guide the fluid to the position of the filter assembly 2 in a spiral shape, so that the fluid can smoothly enter the dirt filtering path, and then rotate around the filter assembly for filtering.

[0054] In the above embodiment, a release component 10023 is also provided on the dust cup 100 for driving the movable cover body 1002 to separate from the dust cup 100, wherein the release component 10023 is located on the bottom end surface of the dust cup 100, wherein when the release component 10023 moves inward, at least a portion of the movable cover body 1002 moves along a predetermined path to a position away from the dust cup 100, and the front end of the first dust collecting area 1004 and the front end of the second dust collecting area 1005 form an open state.

[0055] Specifically, the upper end of the movable cover 1002 is connected to the fixed end on the front end plate 1006, and the movable cover 1002 can move between a first position and a second position. When the movable cover 1002 is in the first position, the movable cover 1002 is buckled on the outside of the first dust collection area 1004 and the second dust collection area 1005, and the front ends of the first dust collection area 1004 and the second dust collection area 1005 are both closed structures. At this time, the dirt filtered out by the filter assembly 2 is stored in the first dust collection area 1004 and the second dust collection area 1005.

[0056] When the button in the release component 10023 is pressed to move the button inward, the movable cover body 1002 can move from the first position to the second position with the upper end as the axis. At this time, the movable cover body 1002 is separated from the first dust collecting area 1004 and the second dust collecting area 1005. The first dust collecting area 1004 and the second dust collecting area 1005 are both in an open state. The filtered dirt in the first dust collecting area 1004 and the second dust collecting area 1005 can be cleaned from the outside of the dust cup 100 through the open ends of the first dust collecting area 1004 and the second dust collecting area 1005.

[0057] In the above embodiment, the drainage portion 101 includes a front panel 1017 that is snapped onto the outside of the spiral channel 1012, wherein the upper end portion of the inner wall surface of the front panel 1017 is connected to the edge of the front end portion of the spiral channel 1012, thereby forming the front end surface of the spiral channel 1012.

[0058] Furthermore, an upper through hole is separately provided at the upper end of the front panel 1017 , and the upper through hole forms an inlet end 1011 communicating with the spiral channel 1012 .

[0059] In this embodiment, since the outlet end 1013 faces the inner wall surface of the arc-shaped guide plate 1003, such a design can easily guide the fluid to the position of the arc-shaped guide plate 1003. In addition, since the spiral channel 1012 corresponds to the arc-shaped guide plate 1003, the two can form a spiral guide axis, so that the fluid entering the dust cup 100 can be guided to the position of the filter assembly 2 along the spiral guide axis, thereby smoothly entering the dirt filter axis AA, and easily separating the dirt in the fluid.

[0060] Furthermore, the drainage part 101 further includes a middle cavity, and the spiral channel 1012 surrounds the outside of the middle cavity. This design makes the overall structure of the drainage part 101 more compact, thereby reducing the space occupied by the drainage part 101 inside the dust cup 100.

[0061] Furthermore, the middle cavity includes a first cavity 1014 and a second cavity 1015 disposed inside the first cavity 1014, a portion of the wall surface of the first cavity 1014 is coplanar with a portion of the wall surface of the second cavity 1015, a front end of the second cavity 1015 abuts against an inner wall surface of the front end plate 1006, a rear end of the second cavity 1015 abuts against a front end of the filter assembly 2, and the interior of the second cavity 1015 is connected to the interior of the second dust collecting area 1005.

[0062] The rear end face of the second cavity 1015 forms an outer edge portion 10151 extending toward the rear end face of the first cavity 1014. When the front end of the filter assembly 2 is placed inside the first cavity 1014, the front end of the filter assembly 2 abuts against the outer edge portion 10151. Two first clamping blocks 10141 are provided on the inner wall surface of the first cavity 1014 at intervals.

[0063] In addition, when the drainage portion 101 is placed inside the dust cup 100 , the front end of the second cavity 1015 faces the second dust collecting area 1005 , and the filtered fine dirt can be guided into the second dust collecting area 1005 through the second cavity 1015 .

[0064] In addition, since a portion of the wall surface of the first cavity 1014 is coplanar with a portion of the wall surface of the second cavity 1015 , such a design can simplify the structure of the drainage portion 101 .

[0065] In addition, the front panel 1017 also includes a lower through hole 1018 opened on the lower end portion. When the front panel 1017 is arranged on the front end surface of the spiral channel 1012, the edge of the lower through hole 1018 is arranged on the edge of the front end surface of the second cavity 1015, so that the lower through hole 1018 is connected to the second cavity 1015.

[0066] In this embodiment, the drainage portion 101 further includes a support portion 1016, wherein the support portion 1016 surrounds the outer side of the second cavity 1015 and contacts the inner wall surface of the arc-shaped guide plate 1003. By providing the support portion 1016, a stable support effect can be provided for the drainage portion 101.

[0067] Specifically, the support portion 1016 is located below the second cavity 1015 and surrounds a portion of the second cavity 1015 .

[0068] Furthermore, the other end of the spiral channel 1012 abuts against the support portion 1016 .

[0069] Preferably, the support portion 1016 is shaped as an inwardly concave arc structure. This design not only makes it easy for the top end face of the support portion 1016 to surround the outside of the second cavity 1015 and contact a portion of the wall surface of the second cavity 1015, but also makes it easy to contact the inner wall surface of the arc guide plate 1003.

[0070] In this embodiment, most of the filter assembly 2 is located above the arc-shaped guide plate 1003. This design facilitates the filter assembly 2 to filter and separate the fluid guided by the arc-shaped guide plate 1003. Since the rear end of the arc-shaped guide plate 1003 forms a dust outlet 10031, the large particles of dirt filtered and separated by the filter assembly 2 can be guided to the inside of the first dust collection area 1004.

[0071] In this embodiment, the filter assembly 2 includes a filter screen cover a200, a filter cone 201, a filter screen cover b202, a sheet filter layer 204 and a mounting plate 203, the filter screen cover a200 is sleeved on the outside of the filter cone 201 and the filter screen cover b202, the filter screen cover b202 is connected to the front end surface of the mounting plate 203, the sheet filter layer 204 is removably embedded in the interior of the mounting plate 203, and is located downstream of the filter screen cover b202, wherein the front end of the filter screen cover a200 is embedded in the interior of the first cavity 1014, the rear end of the filter screen cover a200 is connected to the mounting plate 203, the front end of the filter cone 201 is abutted against the rear end of the second cavity 1051, and the rear end of the filter cone 201 is connected to the mounting plate 203.

[0072] In the above embodiment, the shape of the filter screen cover a200 is similar to a cone structure. In this way, a larger filtering area can be formed on the outside of the filter screen cover a200.

[0073] Furthermore, two first card grooves 2001 are provided on the outer wall surface of the filter screen cover a200 and close to the front end surface of the filter screen cover a200, and two second card blocks 2002 are provided on the inner wall surface of the filter screen cover a200 and close to the rear end surface of the filter screen cover a200.

[0074] When the front end of the filter screen cover a200 is placed inside the first cavity 1014 , the two first card slots 2001 respectively cooperate with the two first card blocks 10141 , thereby fixing the front end of the filter screen cover a200 inside the first cavity 1014 .

[0075] In the above embodiment, the filter cone 201 is provided with a slot portion 2010 , a cone portion 2011 and an air inlet portion 2012 which are connected to each other.

[0076] Furthermore, when the filter cone 201 is placed inside the filter screen cover a200, the slot portion 2010 extends to the outside of the filter screen cover a200. When the front end of the filter assembly 2 is embedded in the first cavity 1014, the outer edge portion 10151 in the second cavity 1015 is embedded in the slot portion 2010, so that the interior of the filter cone 201 is connected to the interior of the second cavity 1015, and the fine dirt filtered out by the filter cone 201 can enter the second dust collecting area 1005 through the second cavity 1015.

[0077] Furthermore, the air inlet portion 2012 is composed of a plurality of blades 20121, and a gap is formed between two adjacent blades 20121, and the gap forms an air inlet, so that the airflow filtered by the filter cover a200 can enter the interior of the filter cone 201 through a plurality of air inlets for further filtration to filter out fine impurities in the airflow.

[0078] Since there are multiple air inlets, after the airflow passes through the filter screen a200, it can enter the interior of the filter cone 201 from the air inlet closest to it, making it easy to guide the airflow.

[0079] In the above embodiment, the filter screen b202 is placed inside the filter cone 201. When the airflow filtered by the filter cone 201 is guided to the position of the filter screen b202, the airflow can be filtered again by the filter screen b202 to separate the tiny particles in the airflow.

[0080] In the above embodiment, the filter screen cover b202 is arranged on the front end surface of the mounting plate 203.

[0081] Furthermore, the mounting plate 203 includes a mating component 2031 surrounding the outer side of the filter screen cover b202 and cooperating with the air inlet portion 2012, an annular wall 2032 surrounding the outer side of the mating component 2031, and an inner cavity formed on the rear end face of the mounting plate 203, wherein a second card slot 20321 cooperating with the second card block 2002 is provided on the annular wall 2032, and the sheet filter layer 204 is removably embedded in the inner cavity.

[0082] When the filter cone 201 is sleeved on the outside of the filter screen cover b202 , the air inlet portion 2012 in the filter cone 201 abuts against the matching component 2031 .

[0083] Furthermore, the matching component 2031 is composed of a plurality of matching protrusions 20311. The tip of the blade 20121 contacts the matching protrusion 20311.

[0084] Among them, an assembly groove is provided on the surface of the matching protrusion 20311, and the end of the blade 20121 is embedded in the assembly groove.

[0085] Since the annular wall 2032 is provided with a second slot 20321 matched with the second block 2002 , the end of the filter screen cover a200 can be set on the mounting plate 203 through the matched second block 2002 and the second slot 20321 .

[0086] In this embodiment, since the end of the arc-shaped guide plate 1003 is close to the front end surface of the mounting plate 203, the opening area of ​​the dust outlet 10031 is smaller, which can further prevent the dirt in the first dust collecting area 1004 from moving toward the position of the filter assembly 2.

[0087] Preferably, the distance from the end of the arc-shaped guide plate 1003 to the front end surface of the mounting plate 203 is no more than 2.1 cm.

[0088] In the above embodiment, a first pressing part 10021 and a second pressing part are also provided on the dust cup 100 for controlling the separation or assembly of the dust cup 100 from the shell, wherein when the first pressing part 10021 and the second pressing part move inward at the same time, the dust cup 100 can be removed from the shell and thus separated from the shell.

[0089] The dust collecting assembly provided in this embodiment has the characteristics of compact structure. The spiral channel cooperates with the arc-shaped guide plate, so that the fluid entering the dust cup can be quickly guided to the position of the filter assembly along the spiral axis, and smoothly enter the dirt filtering path, and rotate around the filter assembly, thereby improving the filtering effect. In addition, since the arc-shaped guide plate is located between the filter assembly and the first dust collecting area, the arc-shaped guide plate not only has the function of guiding the fluid, but also has the effect of blocking dust, and can prevent the dirt in the first dust collecting area from moving to the position of the filter assembly without setting a dust blocking ring.

[0095] Specifically, the vacuum cleaner includes a front end portion consisting of a suction pipe 3, a dust collecting component 1 and a part of a shell 4, a rear end portion consisting of an airflow generating component 5 and another part of the shell 4, and a lower end portion consisting of a handle 6 and a power supply component 7, wherein the lower end portion is located directly below the rear end portion, and the bottom end surface of the lower end portion forms a support surface for the vacuum cleaner during placement, and at the same time, the length of the support surface is roughly the same as the length of the rear end portion 2013. Such a design can provide a good support effect for the vacuum cleaner.

[0096] Further, a part of the power supply component 7 is located directly below the airflow generating component 5. The power supply component 7 includes a first part arranged in an inclined shape and a second part arranged horizontally.

[0097] Preferably, both the first portion and the second portion are located directly below the airflow generating component 5 .

[0098] Such a design enables the center of gravity of the airflow generating assembly 5 and the center of gravity of the power supply assembly 7 to be roughly in the same projection area, thereby preventing the vacuum cleaner from tilting toward its front or rear position, thereby further improving the supporting effect for the vacuum cleaner.

[0099] In addition, the dust cup 100 is provided with a first pressing portion 10021 and a second pressing portion 10022 for controlling the separation or assembly of the dust cup 100 and the housing 4, wherein when the first pressing portion 10021 and the second pressing portion 10022 move inward at the same time, the dust cup 100 can be removed from the housing 4, thereby being separated from the housing 4. After the dust cup 100 is removed from the housing 4, it is also convenient to clean the dust cup 100 and the filter assembly 2.

[0100] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
