Embodiments of the mid-inlet air guide structure and the mid-inlet vacuum cyclone cleaner including the same according to the present invention will be described with reference to the accompanying drawings, in which the parts may be exaggerated or reduced in size or scale for clarity and convenience in the description. In the following description and/or claims, when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements may be present; when an element is referred to as being "directly connected" or "directly coupled" to another element, there are no intervening elements present, and other words used to describe the relationship between the elements or layers should be interpreted in the same manner. For ease of understanding, like elements in the following embodiments are described with like reference numerals.
Please refer to fig. 1, 2 and 3, which are a structural diagram, an exploded view and a schematic diagram of a central air intake flow guiding structure of a central air intake vacuum cyclone dust collector according to a first embodiment of the present invention. As shown in fig. 1 and 2, the central intake vacuum cyclone cleaner 1 includes a housing 10, a motor 11, a fan 12, a central intake air guide structure 13, and a battery 14.
The fan 12 and the motor 11 are arranged inside the casing 10, and the fan 12 is connected with the motor 11; in addition, the housing 10 is also provided with switches and other elements.
The middle air inlet flow guide structure 13 is connected with the fan 12. The middle air intake guiding structure 13 includes a middle air intake pipe 131, a centrifugal outer pipe 132, and an exhaust inner pipe 133. The center intake pipe 131 includes a first intake port I1 and a first exhaust port O1. The center inlet pipe 131 is connected to the centrifugal outer pipe 132 through a first exhaust port O1. The inner exhaust pipe 133 includes a second inlet I2, and the centrifugal outer pipe 132 is connected to the inner exhaust pipe 133 through the second inlet I2. The second air inlet I2 is provided with a first screen F1, and the exhaust inner pipe 133 is also provided with a second screen F2.
The battery 14 is disposed at the bottom of the housing 10, and can be a rechargeable battery and can be replaced detachably, so as to facilitate charging or replacement by a user.
In addition, the second outlet O2 has a third screen F3, the third screen F3 can be used for the last filtering, and the exhausted air can be cleaner through the three filtering processes formed by the first screen F1, the second screen F2 and the third screen F3.
As can be seen from fig. 3, the central air inlet flow guide structure 13 adopts a special common central shaft structure. Namely, the centrifugal outer pipe 132 covers the exhaust inner pipe 133, and the exhaust inner pipe 133 covers the middle-positioned air inlet pipe 131; in this way, the central axis of the center intake pipe 131 overlaps the central axis of the centrifugal outer pipe 132 and the central axis of the exhaust inner pipe 133, so that the center intake pipe 131, the centrifugal outer pipe 132, and the exhaust inner pipe 133 have a common central axis M.
The motor 11 drives the fan 12 to generate suction force, so that air flow flows into the central air inlet pipe 131 through the first air inlet I1 and is exhausted from the exhaust inner pipe 133 through the centrifugal outer pipe 132.
The common central shaft structure makes the structure of the central air inlet flow guide structure 13 compact, so that the volume and the weight are both greatly reduced. In addition, the air flow path formed by the common central axis structure is simple and direct, greatly simplifying the structure, enabling the air flow to flow smoothly, and thus effectively improving the suction force of the mid-inlet vacuum cyclone cleaner 1. In addition, the air flow sucked from the first air inlet I1 enters the middle air inlet pipe 131, then enters the centrifugal outer pipe 132, and directly enters the exhaust inner pipe 133 through the first filter screen F1 at the bottom of the centrifugal outer pipe 132, so that the air flow can enter the exhaust inner pipe 133 from the bottom of the centrifugal outer pipe 132 and pass through the first filter screen F1, and a better centrifugal filtering effect can be achieved.
In addition, the air flow is discharged from the air outlet at the upper side of the inner exhaust pipe 133, and the flowing direction of the air flow in the inner exhaust pipe 133 is the same as the flow direction of the air flow sucked by the first air inlet I1, so the inner exhaust pipe 133 is more completely integrated in the middle-mounted air intake vacuum cyclone dust collector 1 of the present embodiment, and the overall volume is greatly reduced.
Furthermore, since the air flow is discharged from the air outlet on the upper side of the inner exhaust pipe 133, and the flowing direction of the air flow in the inner exhaust pipe 133 is the same as the flowing direction of the air flow sucked by the first air inlet I1, the flowing air flow can directly flow out without other intermediate structures, the dust can be prevented from remaining when passing through a corner, and the dust remaining is further reduced by the first filter screen F1 when the air flow flows into the inner exhaust pipe 133, so that a better cleaning effect can be achieved, a stronger suction force can be achieved, and the power saving effect is improved.
The central inlet vacuum cyclone cleaner 1 of the present embodiment is a gun type cleaner of a hand-held type, but this is merely an example; the middle air inlet flow guide structure 13 can be applied to various types of dust collectors, and is very wide in application.
As mentioned above, the dust barrel (i.e. the middle air intake guiding structure 13) of the present embodiment has a cyclone centrifuge structure inside, and the center of the front end of the dust barrel cover is provided with the through air inlet (i.e. the first air inlet I1), and is characterized in that the dust barrel (i.e. the middle air intake guiding structure 13) has a dust-gas separator inside, and the air inlet (i.e. the first air inlet I1) of the separator is located at the center of the front end of the dust barrel, and guides the dust gas to the compressed dust collecting area P in the dust barrel, and the dust gas is separated, so that the structure can form the above-mentioned common central axis structure, and the formed air flow path is simple and direct, and the structure is greatly simplified, so that the air flow can smoothly flow, and the suction force of the middle air.
Of course, the above description is merely exemplary, and the components of the central air inlet vacuum cyclone cleaner 1 and the central air inlet flow guiding structure and their coordination relationship may be changed according to actual requirements, and the invention is not limited thereto.
Referring to fig. 4, a first schematic view of an airflow path of a mid-inlet air guide structure of a mid-inlet vacuum cyclone cleaner in accordance with a first embodiment of the present invention is shown. As shown, the arrow a indicates the air flow path, and the air flow enters the central air inlet pipe 131 from the first air inlet I1 and then flows into the centrifugal outer pipe 132 from the first air outlet O1. Next, the airflow swirls in the outer centrifugal tube 132 to generate a cyclone separation effect to separate dust in the airflow by centrifugal force, and the dust remains at the bottom of the outer centrifugal tube 132. Then, the air flow enters the inner exhaust pipe 133 through the second air inlet I2 and the first screen F1, passes through the second screen F2, and finally flows out from the second exhaust port O2 at the rear end of the housing 10 through the third screen F3. In one embodiment, the front end of the central air guiding structure 13 may have a detachable structure for the user to discard the dust.
Of course, the above is merely an example, and the air flow path of the central air intake guiding structure 13 may vary according to actual requirements, and the invention is not limited thereto.
It is worth mentioning that most of the current cyclone separation type dust collectors adopt a closed type independent capsule centrifugal dust barrel design, and the closed type independent capsule centrifugal dust barrel is structurally designed in such a way that an independent air inlet rubber pipe opening is additionally arranged beside the outer wall of the closed type independent capsule centrifugal dust barrel and extends to the upper aperture of the independent capsule centrifugal dust barrel. In addition, a side suction aperture is additionally arranged outside the independent capsule centrifugal dust barrel, and the motor drives the fan blades to suck airflow with dust into the barrel together, and then the airflow is separated from the dust. Then, the dust is compressed in the independent capsule centrifugal dust barrel, and the clean air flow is discharged in the reverse direction. The above-mentioned airflow path has many curves and corners, which obstruct the airflow direction and reduce the suction force of the cleaner, so that it is difficult to achieve the convenience of operation and the desired effect in use. In addition, the air inlet aperture is additionally arranged beside the independent capsule centrifugal dust barrel on the air flow path of the independent capsule centrifugal dust barrel, so that the air flow can flow into the independent capsule centrifugal dust barrel, and the air outlet is arranged at the other end of the independent capsule centrifugal dust barrel to generate centrifugal force.
On the contrary, according to the embodiment of the invention, the middle air inlet flow guide structure is provided with the middle air inlet pipe, the centrifugal outer pipe and the exhaust inner pipe, the centrifugal outer pipe covers the exhaust inner pipe, and the exhaust inner pipe covers the middle air inlet pipe, so that the central shaft of the middle air inlet pipe is overlapped with the central shaft of the centrifugal outer pipe and the central shaft of the exhaust inner pipe, the common central shaft structure greatly simplifies the structural complexity, the air flow can smoothly flow in the middle air inlet flow guide structure, the air flow resistance is greatly reduced, and the suction force of the middle air inlet vacuum cyclone dust collector can be effectively improved.
In addition, according to the embodiment of the present invention, the central air intake flow guiding structure has the above-mentioned common central axis structure, which can greatly simplify the structural complexity, so that the air flow can smoothly flow in the central air intake flow guiding structure, thereby reducing the load of the motor, reducing the power consumption, and meeting the requirements of energy saving and environmental protection.
In addition, according to the embodiment of the present invention, the central air intake guiding structure has the aforementioned common central axis structure, which can provide an excellent centrifugal effect to effectively filter the dust, and the strong centrifugal airflow can effectively compress the dust, thereby achieving an excellent performance.
In addition, according to the embodiment of the invention, the common central shaft structure of the central air inlet flow guide structure greatly simplifies the structure complexity, so that the volume and the weight can be reduced simultaneously, and the use is very convenient.
Furthermore, according to the embodiment of the invention, the common central shaft structure of the central air inlet flow guide structure can be applied to various dust collectors, so that the application range is wider. From the above, the present invention is a patent element with advancement.
Referring to fig. 5, a second schematic view of the air flow path of the mid-inlet air guide structure of the mid-inlet vacuum cyclone cleaner in accordance with the first embodiment of the present invention is shown. As is apparent from the figure, due to the special common central axis structure of the central air intake guiding structure 13, the direction D1 of the air flow flowing from the first air inlet I1 into the central air intake pipe 131 is the same as the direction D2 of the air flow exhausted from the exhaust inner pipe 133, so the air flow path is simple and direct, the structure is greatly simplified, and the volume and weight of the central air intake guiding structure 13 are greatly reduced.
