Description

Technical Field

[0001] The present invention belongs to the field of electromechanical technology, and in particular relates to a garbage separator and a cleaning device. Background Art

[0002] With the development of society and the continuous improvement of people's living standards, vacuum cleaners, as a household cleaning appliance, have become increasingly common in homes. A vacuum cleaner generally uses a fan to drive the impeller to rotate at high speed, creating negative air pressure within a sealed housing. This draws dirt, debris, and other contaminants into the vacuum cleaner. The air then separates the contaminants from the air, retaining them in a designated location, while the clean air is expelled from the vacuum cleaner.

[0003] Currently, vacuum cleaners commonly use dust bags or cyclone separators to separate dirt from air. Both separation devices have their drawbacks: dust bags require frequent replacement, which is neither economical nor environmentally friendly. Cyclone separators are relatively large and consume a lot of pressure during operation. Furthermore, cyclone separators have a complex structure and are difficult to design. Their separation efficiency is affected by numerous structural parameters, and mold requirements are also very high. As a result, most cyclone separator products do not have good cyclone separation performance. Unseparable dirt, such as dust, will gradually clog downstream filters, such as HEPA filters, causing the vacuum cleaner's suction power to decrease over time, seriously affecting the user experience. Summary of the Invention

[0004] The purpose of the present invention is to provide a garbage separator and cleaning equipment that can efficiently separate air and dirt, so as to solve the technical problem that the cyclone separation effect of the existing cyclone separator is not ideal.

[0007] The garbage separator provided by the present invention has a simple structure and a small size. It can effectively separate garbage from the sucked fluid through the rotating rotary separator. When used in cleaning equipment, it can effectively slow down the suction attenuation rate of the cleaning equipment. In addition, the rotation of the rotary separator is also conducive to keeping the through holes on its surface clean.

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the technical solutions of the present invention are further described in detail below in conjunction with specific implementation methods and corresponding drawings. It should be understood that the specific implementation methods described herein are only used to illustrate this patent in detail and do not limit the scope of protection of the present invention in any way.

[0028] The terms "top," "bottom," "above," "below," and "on" used in the description of embodiments of the present invention refer to relative positions of components of a device, such as the relative positions of top and bottom substrates within a device. It will be understood that devices are multifunctional regardless of their orientation in space.

[0029] For the sake of convenience, in the embodiment of the present invention, the dust bin 1 is defined as being vertically arranged, and the open end of the rotary separator 2 is directed toward the top of the dust bin 1. In actual use, the orientation of the garbage separator or cleaning device may not be set in accordance with the above definition.

[0030] The present invention provides a garbage separator, such as Figure 2 As shown, it includes a dust bin 1, a rotary separator 2 and a drive motor 3; the structure of the rotary separator 2 is as shown in FIG. Figure 3 As shown, it is a hollow cylindrical structure with one end open, and a plurality of through holes are provided on its surface; the rotary separator 2 is arranged in the dust bin 1, and its open end faces the top of the dust bin 1; the drive motor 3 is arranged in the hollow cavity of the rotary separator 2, and the drive shaft of the drive motor 3 is connected to the chassis of the rotary separator 2, and the drive motor 3 can drive the rotary separator 2 to rotate around its axis in a predetermined direction and speed; the open end of the rotary separator 2 is used as the dividing line between the upper and lower sections of the dust bin 1, and a fluid outlet is provided on the barrel wall of the upper half of the dust bin 1, and a fluid inlet 4 is provided on the side wall of the lower half of the dust bin 1.

[0031] When the garbage separator provided by the present invention is used to separate air and garbage from a fluid, the rotary separator 2 rotates in a predetermined direction and at a predetermined speed under the drive of the drive motor 3, stirring the air at a high rate in the center of the dust bin 1 and forming a negative pressure zone in the middle of the dust bin 1, so that the air in the dust bin 1 forms a cyclone-like effect. The fluid carrying garbage enters the dust bin 1 through the fluid inlet 4 and, under the influence of the negative pressure, moves toward the rotary separator 2. Large particles of dirt and small particles of dust in the garbage are separated using different separation principles; large particles of dirt will be impacted by the cylindrical surface or bottom disc surface of the rotary separator 2 and thus thrown to the bottom of the dust bin 1; small particles of dust are separated to the bottom of the dust bin 1 under the action of the air cyclone in the dust bin 1. The air in the fluid can then pass through the through holes on the surface of the rotary separator 2 and then be discharged from the dust bin 1 through the fluid outlet, achieving efficient separation from the garbage.

[0032] In the garbage separator provided by the present invention, the structure of the rotary separator 2 can be as follows Figure 3 The cylindrical shape shown can also be conical, cylindrical, quasi-cylindrical or quasi-conical.

[0033] The rotation speed of the rotary separator 2 can be determined according to actual use requirements.

[0034] The through holes provided on the surface of the rotating separator 2 can be selected from various common through hole shapes and distribution arrangements. Preferably, the through holes are evenly distributed on the rotating separator.

[0035] The size of the through hole is set so that garbage cannot easily pass through the through hole.

[0036] Preferably, the through hole is a circular hole or a square hole.

[0037] Further preferably, the diameter or side length of the through hole is 2-4 mm.

[0038] The distribution range of the through holes on the rotary separator 2 can be as follows Figure 3 As shown, through holes are provided on the side wall and the bottom plate of the rotary separator 2; Figure 4 As shown, through holes are provided only on the side walls of the rotary separator 2 .

[0039] The installation position of the driving motor 3 is not limited to the hollow cavity of the rotating separator 2, and can also be set at other positions, as long as its driving shaft is connected to the rotating separator 2 and can drive the rotating separator 2 to rotate in a predetermined direction.

[0040] In the garbage separator provided by the present invention, preferably, the fluid inlet 4 and the rotary separator 2 do not overlap at all in the axial direction of the rotary separator 2, and the top end of the fluid inlet 4 is located lower than the bottom end of the rotary separator 2. This prevents the fluid entering the dust bin 1 from the fluid inlet 4 from directly impacting the surface of the rotary separator 2, thereby extending the service life of the rotary separator 2 and reducing noise.

[0041] In the garbage separator provided by the present invention, preferably, a garbage cleaning port is provided at the bottom of the dust bin 1, and a dust bin cover 5 is provided on the garbage cleaning port. The dust bin cover 5 is convenient to open to clean the garbage in the dust bin 1 and keep the dust bin 1 clean.

[0042] The present invention also provides a cleaning device, including a garbage separator, a first filter assembly 6 and a fan 7, wherein the first filter assembly 6 is arranged at the open end of the rotary separator 2, and the fan 7 is arranged on a side of the first filter assembly 6 away from the rotary separator 2.

[0043] The cleaning device provided by the present invention may include but is not limited to a vacuum cleaner.

[0044] Figure 1-2 A handheld vacuum cleaner is shown, comprising the above-mentioned garbage separator, a first filter assembly 6 and a fan 7. The first filter assembly 6 is arranged at the open end of the rotary separator 2, the fan 7 is arranged at the top of the dust bin 1, and a handheld handle 9 is provided on the side wall of the dust bin 1.

[0045] In the vacuum cleaner provided by the present invention, air in the fluid, under the suction provided by the fan 7, passes through the through-holes on the surface of the rotary separator 2, is filtered by the first filter assembly 6, and is discharged from the fluid outlet into the dust container 1. Because the rotary separator 2 efficiently separates air and trash, the air passing through the first filter assembly 6 is ensured to be clean, preventing contamination and clogging of the first filter assembly 6 by trash. This ensures that the suction power of the cleaning device is not easily attenuated even after long-term use.

[0046] In the vacuum cleaner provided by the present invention, preferably, a second filter assembly 8 is provided between the first filter assembly 6 and the fluid outlet to filter the air filtered by the first filter assembly 6 again, thereby further improving the cleanliness of the air discharged from the dust bin 1.

[0047] In the vacuum cleaner provided by the present invention, both the first filter assembly 6 and the second filter assembly 8 may be air filters commonly used in the field of cleaning equipment, such as HEPA.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
