Description

Dust bucket assembly and vacuum cleaner

Technical Field

The invention relates to the technical field of cyclone separator dust collecting devices, and in particular to a dust collecting bucket assembly and a dust collector.

Background Art

With the rapid development of small household appliances technology and the continuous improvement of people's living standards, vacuum cleaners have become one of the essential appliances in people's daily lives.

The existing cyclone vacuum cleaner mainly makes the airflow containing dust sucked in rotate at a certain high speed, so that dust particles with larger mass than air are separated. The existing cyclone vacuum cleaner is generally provided with a multi-stage cyclone filtration system to better separate the dust. After the last stage of cyclone filtration system separation, the air separated by the cyclone is extracted from the outlet of the cyclone vacuum cleaner, but the air extracted from the outlet of the cyclone vacuum cleaner still contains small particles of dust. The existing design usually designs the outlet on the cone cover, and the outlet is a straight-through hole. After the air is extracted from the outlet, it passes through the filter to filter the small particles of dust in the air. However, since the straight-through hole outlet cannot form a swirl of air, the airflow flowing out of the outlet can only contact a local area of the filter, causing the local area of the filter to become increasingly dirty, and the other parts are not used.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

With the rapid development of small household appliances technology and the continuous improvement of people's living standards, vacuum cleaners have become one of the essential appliances in people's daily life. After the vacuum cleaner is powered on, the fan will generate high suction and pressure at a high speed. Under the action of suction and pressure, the air is discharged at a high speed, causing a negative pressure difference between the inside of the vacuum cleaner and the external atmospheric pressure. Under the action of this pressure difference, dust and dirt are sucked in with the air, and dust, dirt and other impurities are retained in the dust collection container, while the air is discharged after purification. The cyclone vacuum cleaners on the market realize the classification of gas and dust impurities through cyclone separation. The multi-cone cyclone separation system is a more advanced structural form with better separation effect. In the multi-cone cyclone separation system, the initial filtration is to separate large particles of dust and other impurities in the air, and entering the multi-cone structure is to separate smaller particles of dust and other impurities in the air.

An embodiment of the present invention provides a dust collecting bucket assembly, which can rotate and guide the airflow flowing out of the outlet to the filter, thereby increasing the contact area between the airflow and the filter, so as to improve the utilization rate of the filter.

FIG. 1 is a cross-sectional schematic diagram of an embodiment of a dust bucket assembly of the present invention. As shown in FIG. 1 , an embodiment of the present invention provides a dust bucket assembly 1000. The dust bucket assembly 1000 includes a dust bucket 100, a cyclone separation device 200, and a filter device 300. The dust bucket 100 has a accommodating chamber QS, and the dust bucket 100 is provided with an air inlet 110. The cyclone separation device 200 is installed in the accommodating chamber QS. The cyclone separation device 200 includes a cone cover 210 and a plurality of cyclone cones 220, and the cone cover 210 includes a first surface 211, a second surface 212, and a plurality of through holes 213 that penetrate the first surface 211 and the second surface 212. The plurality of cyclone cones 220 are connected to the first surface 211 of the cone cover 210, and the plurality of through holes 213 are respectively connected to the plurality of cyclone cones 220. The port of the through hole 213 located on the second surface 212 is provided with a guide surface M1, and the guide surface M1 is spiral. The filter device 300 is arranged on the side where the second surface 212 of the cone cover 210 is located. According to the dust bucket assembly 1000 of the embodiment of the present invention, when the airflow entering the dust bucket 100 containing chamber QS through the air inlet 110 of the dust bucket 100 will enter the cyclone separation device 200 for filtration, the airflow filtered by the cyclone cone 220 in the cyclone separation device 200 will flow out through the through hole 213 of the cone cover 210, and will be guided by the through hole 213 to the filter device 300 located on the side where the second surface 212 of the cone cover 210 is located for further filtration. Since the port of the through hole 213 located on the second surface 212 is provided with a guide surface M1, the airflow passing through the guide surface M1 of the through hole 213 is rotated and guided to the filter device 300, thereby increasing the contact area between the airflow and the filter, thereby improving the utilization rate of the filter.

It should be noted that the multiple cyclone cones 220 can be arranged in an integrated manner or can be arranged individually, which is not limited here. In this embodiment, the multiple cyclone cones 220 are arranged in an integrated structure, and the integrated structure of the multiple cyclone cones 220 is convenient for installation and disassembly.

As shown in Figure 1, in some embodiments, the size of the port of the through hole 213 located on the second surface 212 is larger than the size of the port located on the first surface 211, so that when the airflow filtered by the cyclone cone 220 in the cyclone separation device 200 flows out through the through hole 213 of the cone cover 210, the airflow passing through the guide surface M1 is rotated and guided to the filter, while the contact area with the filter is increased.

As shown in FIG. 1 , in some embodiments, the cone cover 210 includes a plurality of sleeves 214 located on the first surface 211, a plurality of through holes 213 are located in the plurality of sleeves 214 in a one-to-one correspondence, and one end of the sleeve 214 extends into the cyclone cone 220. The airflow passing through the air inlet 110 of the dust bin 100 is first filtered by the filter 400 to filter out the larger dust and garbage in the airflow, and the airflow filtered by the filter 400 flows into the cyclone separation device 200 for filtration, and the cyclone cone 220 in the cyclone separation device 200 filters the airflow filtered by the filter 400. Since the plurality of sleeves 214 on the first surface 211 of the cone cover 210 extend into the cyclone cone 220, the airflow filtered by the cyclone cone 220 passes through the cone cover 210, and then flows to the through holes 213 connected to the plurality of sleeves 214 through the plurality of sleeves 214, and then is guided to the filter by the through holes 213.

It should be noted that an air flow inlet is provided at one end of the cyclone cone 220 extending into the sleeve 214. The air flow entering from the air inlet 110 of the dust bin 100 is filtered by the filter 400, enters the cyclone cone 220 from the air flow inlet of the cyclone cone 220, and after being filtered by the cyclone cone 220, is guided to the filter device 300 through the through hole 213 of the cone cover 210.

As shown in FIG. 1 , in some embodiments, the filter device 300 includes a filter element and a filter bracket, and the filter element is detachably mounted on the filter bracket. When the airflow entering the dust bucket 100 receiving chamber QS through the air inlet 110 of the dust bucket 100 enters the cyclone separation device 200 for filtration, the airflow filtered by the cyclone cone 220 in the cyclone separation device 200 will flow out through the through hole 213 of the cone cover 210, and will be guided by the through hole 213 to the filter device 300 located on the side of the second surface 212 of the cone cover 210 for further filtration. The airflow passing through the guide surface M1 of the through hole 213 is rotated and guided to the filter element of the filter device 300, and has a large contact area with the filter element, so that the filter element can be fully utilized, while improving the airflow efficiency. Since the filter element and the filter bracket are detachably connected, it is more convenient when the filter element needs to be replaced after long-term use.

It should be noted that the filter element in this embodiment can be filter cotton or filter Hepa, or other filtering devices, which is not limited here.

As shown in FIGS. 1-3, in some embodiments, the cyclone separation device 200 further includes a cyclone cone bracket 230 and a dust collecting part 240. The dust collecting part 240 has a dust collecting chamber, and the dust collecting part 240 is installed in the chamber of the dust collecting barrel 100. The cyclone cone bracket 230 is installed on the dust collecting part 240, and a plurality of cyclone cones 220 are installed on the cyclone cone bracket 230. In this embodiment, the dust collecting part 240 having the dust collecting chamber is installed in the accommodating chamber of the dust barrel 100, the cyclone cone bracket 230 is installed on the dust collecting part 240, a plurality of cyclone cones 220 are installed on the cyclone cone bracket 230, and the cyclone cone 220 is connected to the accommodating chamber QS of the dust collecting part 240. When the airflow entering the dust bucket 100 containing chamber QS through the air inlet 110 of the dust bucket 100 enters the cyclone separation device 200 for filtration, the dust and garbage filtered by the cyclone cone 220 falls into the dust collection chamber of the dust collection part 240 connected to the cyclone cone 220. The airflow filtered by the cyclone cone 220 in the cyclone separation device 200 will flow out through the through hole 213 of the cone cover 210, and will be guided by the through hole 213 to the filter device 300 located on the side of the second surface 212 of the cone cover 210 for further filtration. Since the port of the through hole 213 located on the second surface 212 is provided with a guide surface M1, the airflow passing through the guide surface M1 of the through hole 213 is rotated and guided to the filter device 300, thereby increasing the contact area between the airflow and the filter, thereby improving the utilization rate of the filter.

It should be noted that the cyclone cone bracket 230 is provided with a plurality of mounting holes for mounting the cyclone cone, each mounting hole corresponds to a cyclone cone 220, and after the cyclone cone 220 is installed on the cyclone cone bracket 230, the cyclone cone 220 filters the airflow and is used to collect dust and garbage to the outlet of the dust collecting part 240 which is connected to the dust collecting chamber of the dust collecting part 240.

It should be noted that the dust collecting section 240 may have an independent dust collecting chamber, or it may be a dust collecting chamber formed by the inner wall of the integration section 240 and the inner wall of the dust barrel 100 after the dust collecting section 240 is installed in the dust barrel, which is not limited here.

As shown in FIGS. 1-3, in some embodiments, the dust collection barrel assembly 1000 further includes a filter 400. One end of the filter 400 is mounted on the cyclone cone bracket 230, and the other end is sealed and connected to the dust collecting part 240. In this embodiment, the airflow passing through the air inlet 110 of the dust barrel 100 is first filtered by the filter 400 to filter the larger dust and garbage in the airflow, and the airflow filtered by the filter 400 flows into the cyclone separation device 200 for filtration, and the cyclone cone 220 in the cyclone separation device 200 filters the airflow filtered by the filter 400, and then the airflow is guided to the filter through the through hole 213 on the cone cover 210, and the filter filters the airflow filtered by the cyclone separation device 200 again, so that the airflow entering through the air inlet 110 of the dust barrel 100 can be filtered in multiple stages, thereby improving the airflow filtering effect.

As shown in Fig. 4-6, in some embodiments, the port of the through hole 213 located on the second surface 212 is further provided with an outlet surface M2, and the outlet surface M2 is connected to the guide surface M1, and the outlet surface M2 is a straight surface. When the airflow filtered by the cyclone cone 220 in the cyclone separation device 200 flows out through the through hole 213 of the cone cover 210, it first passes through the guide surface M1 to rotate the airflow, forming a larger rotating airflow, and then the rotating airflow flowing through the guide surface M1 is guided to the filter via the outlet surface M2.

As shown in Fig. 4-6, in some embodiments, the air outlet surface M2 is tilted relative to the guide surface M1. In this embodiment, when the airflow enters the dust bucket 100 receiving chamber QS through the air inlet 110 of the dust bucket 100, it will enter the cyclone separation device 200 for filtration. The airflow filtered by the cyclone cone 220 in the cyclone separation device 200 will flow out through the through hole 213 of the cone cover 210, and will be guided by the through hole 213 to the filter device 300 located on the side of the second surface 212 of the cone cover 210 for further filtration. When the airflow passes through the through hole 213 of the guide surface M1 to form a larger rotating airflow, since the air outlet surface M2 is tilted relative to the guide surface M1, the larger rotating airflow formed by the guide surface M1 will have less resistance in the process of passing through the air outlet surface M2 to guide the filter, and can be guided to the filter more smoothly, thereby improving the filter efficiency of the filter for the airflow.

It should be noted that there is a connecting line/boundary line between the air outlet surface M2 and the guide surface M1, and the air outlet surface M2 is tilted relative to the guide surface M1, which means that the air outlet surface M2 and the guide surface M1 at the boundary line are tilted.

As shown in Figures 4-6, in some embodiments, the outlet surface M2 is inclined at an angle of 10 to 30 degrees relative to the guide surface M1, so that a larger rotating airflow is formed by the guide surface M1, and the resistance is reduced when it flows out through the outlet surface M2, and it is guided to the filter more smoothly, thereby improving the filtering efficiency of the filter for the airflow.

FIG. 1 is a cross-sectional schematic diagram of an embodiment of a dust bucket assembly of the present invention; FIG. 7 is a stereoscopic schematic diagram of an embodiment of a vacuum cleaner 10000 of the present invention; and FIG. 8 is a cross-sectional schematic diagram of an embodiment of a vacuum cleaner 10000 of the present invention. As shown in FIG. 1 , FIG. 7 and FIG. 8 , an embodiment of the present invention further provides a vacuum cleaner 10000, comprising a dust bucket assembly 1000 described in any one of the above embodiments, wherein the dust bucket assembly 1000 comprises a dust bucket 100, a cyclone separation device 200 and a filter device 300. The dust bucket 100 has a accommodating chamber QS, and the dust bucket 100 is provided with an air inlet 110. The cyclone separation device 200 is installed in the accommodating chamber QS. The cyclone separation device 200 comprises a cone cover 210 and a plurality of cyclone cones 220, wherein the cone cover 210 comprises a first surface 211, a second surface 212 disposed opposite to each other, and a plurality of through holes 213 penetrating the first surface 211 and the second surface 212. A plurality of cyclone cones 220 are connected to the first surface 211 of the cone cover 210, and a plurality of through holes 213 are respectively connected to the plurality of cyclone cones 220. A guide surface M1 is provided at the port of the through hole 213 located on the second surface 212, and the guide surface M1 is spiral. The filter device 300 is arranged on the side where the second surface 212 of the cone cover 210 is located. According to the dust bucket assembly 1000 of the embodiment of the present invention, when the airflow entering the dust bucket 100 containing chamber QS through the air inlet 110 of the dust bucket 100 will enter the cyclone separation device 200 for filtration, the airflow filtered by the cyclone cone 220 in the cyclone separation device 200 will flow out through the through hole 213 of the cone cover 210, and will be guided by the through hole 213 to the filter device 300 located on the side where the second surface 212 of the cone cover 210 is located for filtration again. Since the port of the through hole 213 located on the second surface 212 is provided with a guide surface M1, the airflow passing through the guide surface M1 of the through hole 213 is rotated and guided to the filter device 300, thereby increasing the contact area between the airflow and the filter, thereby improving the utilization rate of the filter.

As shown in Figures 7-8, in this embodiment, the vacuum cleaner 10000 also includes a fan assembly 2000 and an air inlet K1. The fan assembly 2000 is used to provide a negative pressure environment inside the vacuum cleaner 10000. The air inlet K1 is connected to the air inlet 110 of the dust bucket 100 in the dust bucket assembly 1000. When the fan assembly 2000 starts to work, a negative pressure environment is generated inside the vacuum cleaner 10000, so that the external airflow enters the dust bucket 100 through the air inlet K1 of the vacuum cleaner 10000 for filtration.

In some embodiments, the vacuum cleaner 10000 further includes a mounting base, and the fan assembly 2000 and the dust bucket assembly 1000 are detachably mounted on the mounting base for easy installation and removal, and the dust bucket assembly 1000 is disposed between the sub-fan assembly 2000 and the air inlet K1, and the dust bucket assembly 1000 is detachably connected to the fan assembly 2000. In this embodiment, the fan assembly 2000 is connected to the dust bucket assembly 1000 via a snap-on structure.

As shown in Figure 1, in some embodiments, the size of the port of the through hole 213 located on the second surface 212 is larger than the size of the port located on the first surface 211, so that when the airflow filtered by the cyclone cone 220 in the cyclone separation device 200 flows out through the through hole 213 of the cone cover 210, the airflow passing through the guide surface M1 is rotated and guided to the filter, while the contact area with the filter is increased.

As shown in FIG. 1 , in some embodiments, the cone cover 210 includes a plurality of sleeves 214 located on the first surface 211, a plurality of through holes 213 are located in the plurality of sleeves 214 in a one-to-one correspondence, and one end of the sleeve 214 extends into the cyclone cone 220. The airflow passing through the air inlet 110 of the dust bin 100 is first filtered by the filter 400 to filter out the larger dust and garbage in the airflow, and the airflow filtered by the filter 400 flows into the cyclone separation device 200 for filtration, and the cyclone cone 220 in the cyclone separation device 200 filters the airflow filtered by the filter 400. Since the plurality of sleeves 214 on the first surface 211 of the cone cover 210 extend into the cyclone cone 220, the airflow filtered by the cyclone cone 220 passes through the cone cover 210, and then flows to the through holes 213 connected to the plurality of sleeves 214 through the plurality of sleeves 214, and then is guided to the filter by the through holes 213.

As shown in FIG. 1 , in some embodiments, the filter device 300 includes a filter element and a filter bracket, and the filter element is detachably mounted on the filter bracket. When the airflow entering the dust bucket 100 receiving chamber QS through the air inlet 110 of the dust bucket 100 enters the cyclone separation device 200 for filtration, the airflow filtered by the cyclone cone 220 in the cyclone separation device 200 will flow out through the through hole 213 of the cone cover 210, and will be guided by the through hole 213 to the filter device 300 located on the side of the second surface 212 of the cone cover 210 for further filtration. The airflow passing through the guide surface M1 of the through hole 213 is rotated and guided to the filter element of the filter device 300, and has a large contact area with the filter element, so that the filter element can be fully utilized, while improving the airflow efficiency. Since the filter element and the filter bracket are detachably connected, it is more convenient when the filter element needs to be replaced after long-term use.

As shown in FIGS. 1-3, in some embodiments, the cyclone separation device 200 further includes a cyclone cone bracket 230 and a dust collecting part 240. The dust collecting part 240 has a dust collecting chamber, and the dust collecting part 240 is installed in the chamber of the dust collecting barrel 100. The cyclone cone bracket 230 is installed on the dust collecting part 240, and a plurality of cyclone cones 220 are installed on the cyclone cone bracket 230. In this embodiment, the dust collecting part 240 having the dust collecting chamber is installed in the accommodating chamber of the dust barrel 100, the cyclone cone bracket 230 is installed on the dust collecting part 240, a plurality of cyclone cones 220 are installed on the cyclone cone bracket 230, and the cyclone cone 220 is connected to the accommodating chamber QS of the dust collecting part 240. When the airflow entering the dust bucket 100 containing chamber QS through the air inlet 110 of the dust bucket 100 enters the cyclone separation device 200 for filtration, the dust and garbage filtered by the cyclone cone 220 falls into the dust collection chamber of the dust collection part 240 connected to the cyclone cone 220. The airflow filtered by the cyclone cone 220 in the cyclone separation device 200 will flow out through the through hole 213 of the cone cover 210, and will be guided by the through hole 213 to the filter device 300 located on the side of the second surface 212 of the cone cover 210 for further filtration. Since the port of the through hole 213 located on the second surface 212 is provided with a guide surface M1, the airflow passing through the guide surface M1 of the through hole 213 is rotated and guided to the filter device 300, thereby increasing the contact area between the airflow and the filter, thereby improving the utilization rate of the filter.

As shown in FIGS. 1-3, in some embodiments, the dust collection barrel assembly 1000 further includes a filter 400. One end of the filter 400 is mounted on the cyclone cone bracket 230, and the other end is sealed and connected to the dust collecting part 240. In this embodiment, the airflow passing through the air inlet 110 of the dust barrel 100 is first filtered by the filter 400 to filter the larger dust and garbage in the airflow, and the airflow filtered by the filter 400 flows into the cyclone separation device 200 for filtration, and the cyclone cone 220 in the cyclone separation device 200 filters the airflow filtered by the filter 400, and then the airflow is guided to the filter through the through hole 213 on the cone cover 210, and the filter filters the airflow filtered by the cyclone separation device 200 again, so that the airflow entering through the air inlet 110 of the dust barrel 100 can be filtered in multiple stages, thereby improving the airflow filtering effect.

As shown in Fig. 4-6, in some embodiments, the port of the through hole 213 located on the second surface 212 is further provided with an outlet surface M2, and the outlet surface M2 is connected to the guide surface M1, and the outlet surface M2 is a straight surface. When the airflow filtered by the cyclone cone 220 in the cyclone separation device 200 flows out through the through hole 213 of the cone cover 210, it first passes through the guide surface M1 to rotate the airflow, forming a larger rotating airflow, and then the rotating airflow flowing through the guide surface M1 is guided to the filter via the outlet surface M2.

As shown in Fig. 4-6, in some embodiments, the air outlet surface M2 is tilted relative to the guide surface M1. In this embodiment, when the airflow enters the dust bucket 100 receiving chamber QS through the air inlet 110 of the dust bucket 100, it will enter the cyclone separation device 200 for filtration. The airflow filtered by the cyclone cone 220 in the cyclone separation device 200 will flow out through the through hole 213 of the cone cover 210, and will be guided by the through hole 213 to the filter device 300 located on the side of the second surface 212 of the cone cover 210 for further filtration. When the airflow passes through the through hole 213 of the guide surface M1 to form a larger rotating airflow, since the air outlet surface M2 is tilted relative to the guide surface M1, the larger rotating airflow formed by the guide surface M1 will have less resistance when it passes through the air outlet surface M2 to guide the filter, and can be guided to the filter more smoothly, thereby improving the filter efficiency of the filter for the airflow.

In some embodiments, the outlet surface M2 is inclined at an angle of 10 to 30 degrees relative to the guide surface M1, so that a larger rotating airflow is formed by the guide surface M1, and the resistance is reduced when it flows out through the outlet surface M2, and it is guided to the filter more smoothly, thereby improving the filtering efficiency of the filter for the airflow.
