Detailed Description
The cleaning tool of the present invention will be further described with reference to the accompanying drawings by taking a vacuum cleaner as an example.
Fig. 1 is a schematic structural view of a vacuum cleaner 100 provided in the present application. As shown in FIG. 1, the vacuum cleaner 100 may include a handle 110, a separating assembly 120, and a fan assembly 130, wherein the fan assembly 130 is fixedly coupled to the separating assembly 120 and disposed above the latter, while the separating assembly 120 is fixedly coupled to the fan assembly 130 and the handle 110; when the vacuum cleaner 100 is in operation, an operator can hold the handle 110 to operate the vacuum cleaner 100, the fan assembly 130 is used for generating negative pressure inside the vacuum cleaner 100, and the separation assembly 120 is used for absorbing large-particle impurities and small-particle dust and separating the large-particle impurities and the small-particle dust from air, so that cleaning is completed.
Specifically, fig. 2 is a partial cross-sectional view of the vacuum cleaner 100 provided in the present invention, which shows the internal structure of the separation assembly 120 and the fan assembly 130. As shown, the separating assembly 120 includes a dirt cup 121, a primary filter 122, a drive motor 123, a rotating separator 124, and a dirt suction opening 125; the fan assembly 130 includes an upper cover 131, a secondary filter 132 and a fan 133; wherein the dirt cup 121 and upper cover 131 are fixedly engaged to form a substantially sealed body structure.
Alternatively, as shown in FIG. 2, a step structure is provided at the bottom edge of the upper cover 131, while a complementary step structure is provided at the top edge of the dirt cup 121, which when snapped together complementarily engage to form a sealed body structure.
Alternatively, the upper cover 131 and the dirt cup 121 may be screwed or the like to form a substantially sealed structure.
As shown in fig. 3, in the separating assembly 120, the dirt cup 121 is generally cylindrical and includes a cup 1211 and a bottom cap 1212, and the bottom cap 1212 can be fastened to the bottom of the cup 1211 to form a cavity 1213 for containing the separated large particles and small particles of dirt. A fluid inlet 1214 (fig. 4) is formed on the sidewall of the cup 1211, and the dust suction port 125 is fixedly connected to the sidewall of the cup 1211 and at least partially faces the fluid inlet 1214, so that the mixed fluid of the large particle impurities, the small particle dust and the air flow sucked from the dust suction port 125 can enter the interior of the dust cup 121 through the fluid inlet 1214, and then after separation, the small particle dust and the large particle impurities are retained in the cavity 1213, and the air is discharged out of the dust cup 121 through a fluid outlet 1215 formed in the top of the cup 1211.
Optionally, an engagement mechanism may be provided at the junction of the bottom cap 1212 and the cup 1211, which may include, for example, a spring catch (not shown) and a button 1216 (fig. 4) protrudingly provided on a side wall of the cup 1211. in the engaged state, the spring catch can be compressed by pressing the button 1216 to remove the bottom cap 1212 from the cup 1211 to remove small particle dust and large particle debris, etc. accumulated inside; similarly, the spring clip can be compressed by pressing the button 1216, and the bottom cap 1212 can be snapped onto the bottom of the cup 1211 to securely snap the button 1216 together.
As shown in fig. 2 and 3, inside the bowl 1211, a primary filter 122 is fixedly disposed at the fluid outlet 1215 of the bowl 1211 to filter the separated air, a drive motor 123 is centrally and partially fixedly disposed on the primary filter 122 with its axis of rotation 1232 (fig. 11 a-12 b) oriented downward, and the rotational separator 124 and the axis of rotation 1232 of the drive motor 123 are fixedly connected such that the rotational separator 124 can be rotated about the rotational axis by the drive motor 123.
Specifically, a motor shaft mounting member 1244 (shown in fig. 8 and 9) is provided at a center position on the bottom inner wall of the rotating separator 124, and is used to fixedly connect the shaft 1232 of the driving motor 123. The shaft 1232 of the drive motor 123 may be fixedly coupled to the motor shaft mount 1244 by any of a number of known means, such as, for example, by threading, adhesive bonding, key bonding, or interference fit. The rotating speed of the driving motor 123 can be a constant value, and can also be adjusted according to the working gear of the vacuum cleaner 100; or the driving motor 123 is matched with a constant rotation speed or different rotation speeds according to the operating gear of the cleaner 100.
Preferably, the primary filter 122 partially protrudes from the fluid outlet 1215 of the cup 1211, such that when the dirt cup body 1211 is engaged with the upper cover 131 of the fan assembly 130, the primary filter 122 further seals the engagement interface (step surface) therebetween, enhancing the sealing effect, such that all of the separated air can enter the fan assembly 130 through the primary filter 122.
Here, the rotating separator 124 may have a cylindrical, conical, cylinder-like or cone-like shape with an upper end opened, and it is understood that, in order to achieve the effect of separating the particulate matter from the air, the rotating separator 124 should be opened with separation holes 1243 allowing the clean air to pass through at least in a side surface area 1241.
When the vacuum cleaner 100 of the present application is in operation, the driving motor 123 drives the rotating separator 124 to rotate at a certain speed in a certain direction according to specific use requirements, the mixed fluid containing the small particle dust, the large particle impurities and the air enters the interior of the dirt cup 121 through the fluid inlet 1214 under the negative pressure generated by the fan assembly 130 (described in detail below), and the mixed fluid enters tangentially along the cylindrical surface of the rotating separator 124 and flows along the cylindrical surface of the rotating separator 124 in the rotating direction thereof. Large particle debris in the combined air stream will be struck by the rotating separator 124 and thrown into the chamber 1213 at the bottom of the dirt cup 121. At the same time, the rotation of the rotating separator 124 can agitate the air at a high rate in the direction of fluid entry, creating a cyclone-like effect of the air in the dirt cup 121. The small particles of dirt in the combined air flow are subjected to the cyclonic action and are also separated into the chamber 1213 at the bottom of the dirt cup 121. The air and possibly also the participating particles in the mixed fluid flow at least from the separating openings 1243 distributed over the lateral surface area 1241 of the rotating separator 124 into the primary filter 122 for filtering.
In the vacuum cleaner 100 provided herein, the rotating separator 124 can take many different forms to accomplish the separation of the mixed fluid. The rotating separator 124 of the present application will be described in detail with reference to fig. 5 to 10, taking a cylindrical shape as an example.
Fig. 5 is a structural side view of an embodiment of the rotating separator 124, and the rotating separator 124 is provided with a plurality of uniformly distributed separation holes 1243 in a side surface area 1241, that is, the intervals between adjacent rows of separation holes are the same, the intervals between adjacent columns are also the same, and the sizes of the separation holes 1243 are the same. Here, the side surface area 1241 is at least a circumferential area of the side surface of the rotating separator 124 facing the fluid inlet 1214, so that the mixed air flow entering the dirt cup 121 from the fluid inlet 1214 can directly contact the plurality of separation holes 1213, enhancing the separation effect.
Alternatively, the separation holes 1243 may have various shapes, such as a circle, an ellipse, a rectangle, a diamond, or a polygon, etc. Preferably, as shown in fig. 5, the separation hole 1243 has a circular shape, which can effectively reduce the complexity of manufacturing and increase the efficiency of manufacturing.
In alternative embodiments, different rows or columns of the separation apertures 1243 may have different shapes in the side surface area 1241.
In another embodiment, as shown in FIG. 6, the separation orifice 1243 is a polygonal orifice that is at an angle φ from the rotational axis of the rotational separator 124, i.e., the axial centerline of the separation orifice is at an angle φ from the rotational axis of the rotational separator 124. The inclined polygonal holes distributed on the side surface of the rotating separator 124 make the dirt less likely to pass through and be separated. Meanwhile, as the rotary separator 124 rotates stably, the inclined polygonal holes can cut off hairs in dirt, so that the hairs are prevented from being wound; the air separated by the rotating separator 124 passes through the polygonal holes of its surface and enters the inside of the rotating separator 124 in an oblique direction defined by the polygonal holes.
In the structural side view of another embodiment of the rotating separator 124 depicted in fig. 7, the rotating separator 124 is provided with a plurality of non-uniformly distributed separation holes 1243 in a side surface area 1241. The "uneven distribution" here means that the plurality of separation holes 1243 are unevenly distributed in the axial direction of the rotating separator 124 (i.e., the up-down direction in fig. 7).
Specifically, in the axial direction of the rotational separator 124, the side surface area close to the fluid inlet and the side surface area far from the fluid inlet are distributed with the separation holes 1243 different in size and/or shape, and the interval between adjacent separation hole rows is not constant. In the preferred embodiment of fig. 7, the side surface area includes, in the axial direction, a first sub-area 1241A close to the fluid inlet and a second sub-area 1241B far from the fluid inlet, in which rows of the plurality of separation holes are uniformly distributed, respectively, and in order to ensure the separation effect, the distance between the adjacent rows of the separation holes of the first sub-area 1241A is smaller than the distance between the adjacent rows of the separation holes of the second sub-area 1241B, and the size of each separation hole of the first sub-area 1241A is smaller than the size of the separation hole of the second sub-area 1241B, so that more large particle impurities and small particle dusts cannot pass through the separation holes of the first sub-area 1241A to be separated into the cavity 1213 at the bottom of the dirt cup 121, while the separated air can be discharged out of the dirt cup through the separation holes of the second sub-area as soon as possible. In order to further maintain the balance of the average ventilation area per unit area over the entire side surface area 1241, the number of the separation holes 1243 of the second sub-area 1241B should be made smaller than the number of the separation holes 1243 of the first sub-area 1241A.
Likewise, the separation holes 1243 may have various shapes, such as a circle, an ellipse, a rectangle, a diamond, a regular polygon, or the like. Preferably, in fig. 6, the separation holes 1243 distributed in the first sub-area 1241A have a circular shape, and the separation holes 1243 distributed in the second sub-area 1241B have a square shape.
In the embodiment depicted in fig. 5, 6 or 7, the side surface area 1241 should comprise at least a side area close to the fluid inlet. Preferably, the side surface area 1241 is the entire side surface of the rotating separator 124, i.e. the separation holes 1243 are distributed over the entire side surface of the rotating separator 124.
It is understood that the separation holes 1243 may be provided only on the side surface area 1241 of the rotating separator 124, and the separation holes 1243 may not be provided on the bottom surface area 1242, as shown in fig. 8, on the premise of securing the separation effect. In an alternative embodiment shown in fig. 9 and 10, besides the plurality of separation holes 1243 distributed on the side surface area 1241, the rotating separator 124 may further include a plurality of separation holes 1243 on the bottom surface area 1242 to assist the separation work of the mixed air flow by the separation holes 1243 of the side surface area 1241.
In the embodiment depicted in fig. 9, a plurality of discrete holes 1243 are evenly distributed around the center of a circle on the bottom surface area 1242, with the motor shaft mount 1244 disposed at the center of the circle. Specifically, a plurality of concentric rings are formed around the center, each concentric ring includes a plurality of separation holes 1243 that are equidistantly distributed, and the radial intervals between adjacent concentric rings are the same.
Alternatively, the separation holes 1243 may have various shapes, such as a circle, an ellipse, a rectangle, a diamond, or a polygon, etc. Preferably, in fig. 9, the separation hole 1243 has a circular shape, which can effectively reduce the complexity of manufacturing and increase the processing efficiency.
In further alternative embodiments, the plurality of separation apertures 1243 may be non-uniformly distributed about the center of the circle on the bottom surface area 1242 with the plurality of separation apertures 1243. By "non-uniform distribution" is meant that the separation apertures 1243 in adjacent concentric rings are of different shapes and/or sizes and are not uniformly spaced. For example, the separation holes in the concentric rings may have different shapes and/or sizes in the radial direction, and the spacing between adjacent concentric rings becomes gradually larger in the outward direction from the center of the circle.
Preferably, in this embodiment, the bottom surface area 1242 is the entire bottom surface of the rotating separator 124, i.e. the separation holes 1243 are distributed over the entire bottom surface of the rotating separator 124.
In alternative embodiments, the bottom surface area 1242 may be an edge area of the bottom surface of the rotating separator 124, i.e. the plurality of separation orifices 1243 may be distributed in the form of at least one concentric ring at the edge area of the bottom surface. In the embodiment of fig. 10, only one circular ring in which a plurality of separation holes 1243 are arranged in a circumferential direction is distributed at an edge area of the bottom surface (bottom surface area 1242).
It will be appreciated that for optimal separation, the rotating separator 124 should be made of a material that is strong and lightweight, such as stainless steel, to withstand the large shear stresses it experiences when in contact with the mixed gas stream. Meanwhile, the rotating separator 124 should have smooth side and bottom surfaces so that large-sized foreign materials or small-sized dust in the mixed air flow cannot stick to the surface thereof or get stuck in the separation holes, while protecting the safety of the operator and preventing scratches when the rotating separator is mounted, dismounted, and cleaned.
To obtain a relatively high separation efficiency, the rotary separator of conventional cleaners usually comprises two or more separation stages. The first stage typically comprises a single relatively large cyclone chamber for removing coarse dirt, while the second stage comprises a plurality of relatively smaller cyclone chambers for removing fine dirt. As a result, the overall size of the rotating separator may be relatively large. Another difficulty with rotating separators is that they require high fluid velocities to achieve high separation efficiency. In addition, the fluid moving through the rotating separator typically follows a relatively long path as it flows from the inlet to the outlet. The long path and high velocity result in high aerodynamic losses, such that the pressure drop associated with the rotating separator can be high. With the rotating separator described herein, a relatively high separation efficiency can be achieved in a more compact manner.
Fig. 11a and 11b are schematic structural views of the driving motor 123 of the separating assembly 120. As shown, the driving motor 123 includes a stator 1231, a rotor (inside the motor, not shown), and a rotating shaft 1232. In addition, a plurality of surface protrusions 1233 may be uniformly disposed on the surface of the stator 1231, and by these surface protrusions 1233, the residual particulate matters entering the inside of the rotating separator 124 can be further pulverized and then fall into the cavity 1213 at the bottom of the dirt cup 121 through the separating holes 1243 distributed on the bottom surface area 1242 of the rotating separator 124, so that the air flow entering the primary filter 122 is cleaner, and the primary filter 122 is prevented from being blocked.
In the particular embodiment shown in fig. 11a and 11b, the surface protrusions 1233 are configured as a sheet-like structure, which extends over at least part of the axial length of the stator surface, and whose projection on the stator surface is parallel to the axial direction of the drive motor 123. In addition, each of the surface protrusions 1233 should have the same size to ensure stability when the motor is rotated.
In another embodiment of the drive motor 123 depicted in fig. 12a and 12b, the surface protrusions 1233 are configured as a sheet-like structure, which extends over at least part of the axial length of the stator surface, and whose projection onto the stator surface makes an angle θ with the axial direction of the drive motor 123. In the embodiment where the separation holes 1243 of the rotating separator 124 are inclined polygonal holes as shown in fig. 6, the inclined direction of the inclined polygonal holes is preferably opposite to the inclined direction of the inclined surface protrusions 1233 in this embodiment, so that it is more advantageous to crush and knock off residual particulate matters (e.g., dust) entering the inside of the rotating separator 124.
