Description

Technical Field

[0001] This utility model relates to the field of cleaning appliances, and in particular to an electric filter and a vacuum cleaner. Background Technology

[0002] With the improvement of people's living standards, vacuum cleaners have become increasingly widely used in daily life. In current vacuum cleaners, cyclone separators have replaced dust bag separators for dust separation. Specifically, the airflow carrying dust, sucked into the vacuum cleaner, flows within the cyclone separator. Under the influence of gravity and centrifugal force, the dust settles downwards into the dust collection chamber of the cyclone separator, while the clean airflow, free of dust, flows out of the cyclone separator and returns to the external environment. For example, patent CN110432824B discloses a cyclone structure, a cyclone separator, and a vacuum cleaner.

[0003] In many existing vacuum cleaners, the cyclone cone is prone to getting tangled with hair or large pieces of debris during operation, which reduces the efficiency of dust cup separation and makes it difficult to clean. Utility Model Content

Detailed Implementation

[0038] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it based on the description.

[0039] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0040] Example 1

[0041] Reference Figure 1-10 This embodiment provides an electric filter, including:

[0042] Dust cup 1 is cylindrical and hollow inside, with an air inlet 11 tangentially arranged on the outer wall along the circumference;

[0043] Cyclone assembly 2 includes a bracket 21 connected inside the dust cup 1 and disposed upside down, a filter element 22 disposed on the upper part of the bracket 21, a cyclone cone 23 disposed upside down at the bottom of the bracket 21, and a motor 24 disposed inside the cyclone cone 23.

[0044] The filter assembly 3 includes a filter body 31 that is upside down at the bottom of the cyclone cone 23 and a bearing 32 that rotatably connects the filter body 31 and the cyclone cone 23. The output shaft 241 of the motor 24 is driven to the filter body 31 to drive the filter body 31 to rotate relative to the cyclone cone 23.

[0045] In this invention, the filter body 31 is hollow inside and has a mounting cavity 33 at the bottom. The bearing 32 is fitted inside the mounting cavity 33, and the outer ring of the bearing 32 contacts the inside of the mounting cavity 33. The bottom of the cyclone cone 23 is fitted into the inner ring of the bearing 32, so that the filter body 31 can rotate relative to the cyclone cone 23.

[0046] In this invention, the bottom of the mounting cavity 33 has a downward-facing drive connection hole 34, and the bottom of the cyclone cone 23 has a motor receiving cavity 231 for mounting the motor 24. The bottom of the motor receiving cavity 231 has a shaft hole 232. The output shaft 241 of the motor 24 passes through the shaft hole 232 and is inserted into the drive connection hole 34 for drive connection with the filter body 31. The output shaft 241 of the motor 24 can drive the filter body 31 to rotate through the drive connection hole 34.

[0047] A cover plate 234 for sealing the mounting cavity 33 is provided above the motor 24 to prevent dust and other debris from entering the space where the motor 24 is located.

[0048] like Figure 1-10In this embodiment, the filter body 31 has a split structure, including an upper filter cover 311, a plurality of support plates 312 evenly spaced along the circumferential direction at the bottom of the upper filter cover 311, a mounting plate 313 connected to the bottom of the support, a lower filter cover 314 connected to the bottom of the mounting plate 313, and a filter screen 315 connected between the upper filter cover 311 and the lower filter cover 314 and arranged around the outer periphery of the support plate 312. A through hole 3131 is opened in the middle of the mounting plate 313 to allow the cyclone cone 23 to pass through.

[0049] The interior of the filter lower cover 314 forms an installation cavity 33.

[0050] Reference Figure 6 The upper part of the cyclone cone 23 is provided with several first air guides 233 arranged in a ring.

[0051] Reference Figure 7 In this utility model, the bracket 21 includes a bracket seat 211 connected to the inner wall of the dust cup 1, a hollow bracket column 212 extending downward from the bottom of the bracket seat 211, and a plurality of second air guides 213 opened at the bottom of the hollow bracket column 212. The second air guides 213 connect the interior of the cyclone cone 23 with the interior of the bracket 21. The bracket seat 211 has filter element mounting holes 214 for mounting the filter element 22.

[0052] In this invention, a first sealing ring 25 is provided between the inner wall of the support base 211 and the dust cup 1, and a second sealing ring 26 is provided between the filter body 31 and the support base 211. The first sealing ring 25 is used to ensure the seal between the inner wall of the support base 211 and the dust cup 1, and the second sealing ring 26 is used to achieve the seal during the relative rotation process between the filter body 31 and the support base 211.

[0053] The working principle of this utility model:

[0054] During cleaning, the vacuum cleaner's power source generates a negative pressure inside the cyclone chamber, drawing dirty air into the dust cup 1 through the air inlet 11. Guided by the air inlet 11, the dirty air forms a vortex inside the dust cup 1, passes through the filter screen 315 on the filter body 31, enters the filter body 31, then enters the cyclone cone 23 through the first air guide 233, and then enters the hollow support column 212 of the bracket 21 through the second air guide 213. Finally, it is filtered by the filter element 22. During the cleaning process, the motor 24 drives the filter body 31 to rotate continuously, causing hair, large dust particles and debris, and some small dust particles in the dirty air to be thrown off and collected by the dust cup 1. This prevents them from adhering to the filter body 31 or entering the filter body 31, improving the separation efficiency of the dust cup 1 and making the filter body 31 easier to clean. Small dust particles that enter the filter body 31 with the airflow are eventually filtered by the filter element 22, and the filtered clean air is finally drawn out from the outside of the filter element 22 and discharged from the dust cup 1.

[0055] Example 2

[0056] The only difference between this example and Example 1 is the structure of the cyclone assembly 2:

[0057] Reference Figure 11-12 In this example, the cyclone assembly 2 includes a bracket 21 connected inside the dust cup 1 and a motor 24 located at the bottom of the bracket 21. That is, the cyclone assembly 2 in this example does not include the filter element 22 and the cyclone cone 23. Several second air guides 213 are opened on the side of the bracket 21.

[0058] Example 3

[0059] Reference Figure 11-12 The only difference between this example and Embodiment 1 is that the filter body 31 in this example is an integral structure. The filter body 31 is formed from top to bottom as an upper cover part 316, a filter screen part 317 and a lower cover part 318. The interior of the lower cover part 318 forms an installation cavity 33.
