Figure 1 and 2 schematically show an electrician for use in accordance with one possible embodiment of the present application. A cyclonic vacuum cleaner can be attached and used in conjunction with a power tool not shown to constitute a power tool assembly in accordance with the present application.

The cyclone cleaner uses a negative pressure to generate a suction airflow and a swirling flow to suck the dust generated by the operation of the power tool and separate it from the air. To this end, the cyclonic vacuum cleaner comprises a vacuum generating module 1 , which in the illustrated example is in the form of a motor module 1 . In addition, the cyclone vacuum cleaner further includes a cyclone separation module 2 and a dust collection module 3. These modules are described one by one below.

The motor module 1 mainly includes a bracket 11 and a motor 13 and a fan 14 supported by the bracket 11 and mounted in the common housing 12.

The bracket 11 includes a mounting plate 11a; a pair of plate-like supporting legs 11b projecting downward from the mounting plate 11a; and a flange 11c which is folded outward from each of the supporting legs, respectively.

In the illustrated example, the pair of support legs 11b are plate portions that extend downwardly and are substantially perpendicular to the mounting plate 11a, and the pair of flanges 11c are substantially flush and are fixed in the set by fasteners such as bolts. The substantially horizontally positioned seat plate 31 of the dust module 3 (which will be described later) such that the mounting plate 11a is substantially parallel to the seat plate 31, and the mounting plate 11a and the seat plate 31 are separated by a vertical distance to A space is defined between the outside and the outside.

In the illustrated example, the housing 12 includes upper and lower portions, the upper portion having a lateral dimension greater than the lower portion. The lower portion passes through the mounting hole in the mounting plate 11a, and the step formed between the upper and lower portions abuts against the upper surface of the mounting plate 11a, thereby positioning the housing 12 with respect to the mounting plate 11a. The housing 12 will be securely mounted to the mounting plate 11a by suitable fastening means, for example by means of a form fit, using fasteners such as screws, snap rings or the like.

It will be appreciated that the bracket 11 can have any suitable form as long as the support housing 12 can be supported above the seat pan 31. For example, the mounting plate 11a does not have to be parallel to the seat plate 31, but may be inclined with respect to the seat plate 31 as needed, or even perpendicular thereto. Further, the support leg 11b is not necessarily in the form of a pair of plate portions, but may take various suitable forms, such as in the form of a plurality of rods, as long as the mounting plate 11a can be separated from the seat plate 31 by a distance in the vertical direction. And the space between the two can communicate with the outside world. According to one possible embodiment, the bracket 11 can even be eliminated, but the housing 12 is mounted directly to the seat plate 31. Further, the entire bracket 11 is preferably a single piece bent from a metal plate, but the bracket 11 may also be made in other manners, and the respective portions may be separately formed and reassembled together.

The housing 12 has an air suction port at the upstream end (upper in the drawing) and an air discharge port at the downstream end (lower in the drawing), each of which may be in the form of a hole, a slit or the like. The other parts of the housing 12 are sealed except for the air suction port and the air discharge port. When the motor 13 rotates, the fan 14 is driven to rotate, so that the air is sucked into the casing 12 from the air suction port, and the air is blown through the air discharge port toward the space between the mounting plate 11a and the seat plate 31, or directly toward the outside. The space is blown (for example, in a direction inclined with respect to the seat plate 31, or even perpendicular thereto).

The cyclone separation module 2 mainly includes a cyclone separator 21 defining an internal swirling space and having an input port, an air output port, and a dust output port in communication with the internal swirling space; communicating with the cyclone 21 and the housing 12 The connecting pipe 22 has an upstream port connected to the air outlet port of the cyclone 21 and a downstream port connected to the air suction port of the casing 12; the dust suction pipe 23 is connected to the cyclone 21 and not shown Between the power tools, the proximal end of the suction pipe 23 is connected to the input port of the cyclone 21 through the pipe joint 24, and the distal end is connected to a portion of the power tool adjacent to the place where the dust is generated during operation. Some power tools have a dust shield that at least partially surrounds the tool head, such as a saw blade shroud for a circular saw, a dust cover for an electric drill, etc., in which case the distal end of the suction tube 23 can be connected to dust protection Cover and face the inside of the dust shield. In order to facilitate the connection between the dust suction pipe 23 and the power tool, the attachment fitting 25 may be provided at the distal end of the dust suction pipe 23.

As the end of the dust suction pipe 23 is attached to the power tool, the power supply port in the end of the dust suction pipe 23 is simultaneously connected to the corresponding power output port in the power tool to supply power to the motor 13 using the power source of the power tool, and Simultaneous start and stop of power tools and cyclone cleaners is easy. Of course, the power cord of the motor 13 can also be drawn separately from the housing 12.

The cyclone separator 21 mainly includes: a top wall 21a; a substantially cylindrical vertical side wall 21b extending downward substantially perpendicular to the top wall 21a, the vertical side wall 21b having an axial first end opposite to each other and a second end, the first end is sealingly coupled to the top wall 21a; a conical side wall 21c extending downward from the second end of the vertical side wall 21b, the conical side wall 21c having an axial direction opposite to each other The second end has a smaller diameter than the first end, and the first end of the conical side wall 21c is tightly connected to the vertical end The second end of the straight side wall 21b, the open second end of the conical side wall 21c constitutes a dust output port of the cyclone 21, the top wall 21a, the vertical side wall 21b and the conical side wall 21c define An internal swirling space; an upper and lower penetrating tubular body 21d extending substantially perpendicular to the top wall 21a and extending into the vertical side wall 21b, coaxial with the vertical side wall 21b, thereby defining a central axis of the cyclone 21 And defining a substantially circular annular space between the circular tubular body 21d and the vertical side wall 21b; a mounting flange 21e extending outward from the second end of the conical sidewall 21c, mounting flange 21e and conical sidewall A reinforcing rib 21f may be formed between the 21c to increase the structural strength therebetween, and the mounting flange 21e may be fixed to the seat plate 31 by a fastener such as a bolt. The upper end of the circular tubular body 21d may terminate in the top wall 21a or protrude upward through the top wall 21a. The upper end opening of the circular pipe body 21d constitutes an air output port of the cyclone separator 21.

The cyclone separator 21 is configured to introduce air entrained with dust from the input port, generate a swirling flow inside the cyclone separator 21, so that the dust is separated from the air, and then the clean air is discharged through the air output port, and the dust is discharged through the dust. The port is discharged. In order to enhance the swirl separation effect in the cyclone separator 21, a suitable flow guiding structure 21g may be provided inside the cyclone separator 21.

The cyclone separator 21 can be a single piece that is molded, for example, from plastic. The pipe joint 24 is preferably formed integrally with the cyclone separator 21, for example, molded from the same plastic, or insert molded into the cyclone separator 21 as a metal member.

The pipe joint 24 has a suction pipe connecting section 24a and a cleaner connecting section 24b. The suction pipe 23 can be connected to the suction pipe connection section 24a, for example, to the suction pipe connection section 24a, possibly by means of an additional locking member or connecting piece. The cleaner connecting portion 24b traverses the vertical side wall 21b of the cyclone 21 and defines a through hole leading to the annular space between the circular tube body 21d and the vertical side wall 21b, thereby constituting the cyclone 21 Input port.

In order to improve the air flow condition, the cleaner connecting portion 24b has a gradually increasing flow area from a portion where it merges with the suction pipe connecting portion 24a toward a portion where it merges with the vertical side wall 21b of the cyclone 21. In the illustrated example, the vacuum cleaner engagement section 24b has an outer contour of a trapezoidal table whose height dimension gradually increases toward the vertical side wall 21b.

The central axis of the cleaner attachment section 24b traverses the central axis of the cyclone 21, for example substantially perpendicular, but the two do not intersect, but the central axis of the cleaner engagement section 24b is radially offset relative to the central axis of the cyclone 21, The distance of the offset is such that, viewed in the direction of the central axis of the cleaner engagement section 24b, the cleaner engagement section 24b is located on the radial side of the central axis of the cyclone 21, preferably such that the cleaner engagement section 24b is completely located in the radial direction of the tubular body 21d. Outside (ie suction The projection of the dust catching section 24b in the direction of its central axis does not coincide with the circular tubular body 21d). The vacuum cleaner engagement section 24b is as close as possible to the radially outer boundary of the annular space, for example, the radially outermost portion of the cleaner attachment section 24b with respect to the central axis of the cyclone may be aligned with the radially outermost portion of the annular space. cut. In order to facilitate a smooth transition between the vacuum cleaner engagement section 24b and the vertical side wall 21b, the adjacent portion of the vertical side wall 21b may form a flat portion 21h that smoothly transitions into the cleaner engagement section 24b.

The dust collecting module 3 includes the aforementioned seat plate 31, an elastic gasket 32 attached to the lower surface of the seat plate 31, and a barrel dust collecting container 33 that supports the elastic gasket 32 and the seat plate 31 from below.

The seat plate 31 has a substantially plate shape, has a substantially square outer contour as shown in the drawing or an outer contour such as a circular shape, and the motor module 1 and the cyclone separation module 2 are mounted thereon as described above, and are themselves Again, it rests on the upper edge of the dust collecting container 33, and a substantial seal is achieved between the two by the elastic gasket 32. The elastic gasket 32 may be made of an elastically compressible material such as rubber, and has a sufficient thickness such that when the seat plate 31 carrying the motor module 1 and the cyclone separation module 2 bears against the dust collecting container 33, Under the action of their gravity, the upper edge of the dust collecting container 33 is fully immersed in the elastic gasket 32, not only to achieve the sealing between the seat plate 31 and the dust collecting container 33, but also to help maintain the seat plate 31 relative to the dust collecting container. 33 is stationary, and the seat plate 31 does not move relative to the dust collecting container 33 even when the cyclone cleaner is operated. In order to help keep the seat plate 31 stationary relative to the dust collecting container 33, a corresponding limiting structure (not shown), such as a laterally adjustable snap structure or the like, may be provided on the seat plate 31.

The dust collecting container 33 may be a special container provided by the supplier of the cyclone cleaner (power tool assembly) of the present application, which is provided with the seat plate 31, or may be provided by the user himself (for example, using various common daily buckets, preferably The drum) can be placed on the seat plate 31 carrying the motor module 1 and the cyclone separation module 2 when it is used.

The upper opening edge of the dust collecting container 33 is sized larger than the size of the air output port of the cyclone 21 but smaller than the outer circumference of the seat plate 31. Further, since the dust collecting container 33 itself constitutes the support of the seat plate 31 carrying the motor module 1 and the cyclone separating module 2, the size of the upper opening edge thereof should be sufficiently large to reliably support the seat plate 33 thereon. Not easy to overturn.

A through hole that is aligned with the second end of the conical side wall 21c (which constitutes the dust output port of the cyclone 21) is formed in the seat plate 31 (and the corresponding elastic gasket 32), and the through hole faces the dust collecting container 33. internal.

In tube 23. The dust-laden air is drawn into the annular space in the cyclone 21 through the pipe joint 24 (the input port of the cyclone 21) in the direction indicated by the arrow B, and forms a swirl in the annular space. The dust in the swirl is radially extracted by the centrifugal force and separated from the air, and rotates under its own gravity and finally falls in the direction indicated by the arrow C, and passes through the conical side wall 21c by the cyclone 21 The dust output port falls into the dust collecting container 33. In this way, dust generated in the operation of the power tool is efficiently collected by the cyclone separation. The clean air from which the dust has been separated is drawn into the connecting pipe 22 through the air outlet port of the cyclone 21 through the round pipe body 21d, and then flows into the casing through the air suction port of the casing 12 in the direction indicated by the arrow D. The inside of the fan 12 flows through the fan 14 and the motor 13, and then flows into the space between the mounting plate 11a and the seat plate 31 in the direction indicated by the arrow E through the air discharge port of the casing 12, and finally flows into the outside air as indicated by an arrow F. In this way, dust generated during the operation of the power tool is efficiently collected into the dust collecting container 33.

It will be appreciated that the cyclonic vacuum cleaner of the present application employs a seat plate 31 that can be conveniently supported against the dust collecting container 33 during use. The seat plate 31 can have various suitable shapes, structures, and sizes, and can be specifically designed by those skilled in the art according to practical applications.

It will be appreciated that the negative pressure generating module in the cyclonic vacuum cleaner of the present application may take any suitable form other than the motor module 1.

For example, another possible embodiment of the cyclonic vacuum cleaner of the present application is shown in FIG. 4, wherein the seat plate 31 (and the attached elastic gasket 32) has a downwardly bulging shape, preferably a spherical or conical shape. Or include a plurality of disc-shaped steps protruding step by step. Furthermore, the seat plate 31 preferably has a generally circular outer contour. By the downward bulging shape of the seat plate 31, the seat plate 31 can be applied to the dust collecting containers 33 of various sizes, so that the seat plate 31 can be made into standard parts, and the dust collecting container 33 can be selected as needed, thereby improving The adaptability of the cyclone vacuum cleaner. Further, it is easier to support the seat plate 31 against the dust collecting container 33 without being easily detached. Other aspects of the embodiment shown in Figure 4 are similar to those shown in Figures 1-3 and will not be described in detail herein.

According to the present application, the external cyclone cleaner can provide a large dust collecting capability for the power tool. Further, the motor module 1 and the cyclone separation module 2 of the cyclone cleaner are assembled on the seat plate 31, and have a compact and compact structure. In addition, a seat plate carrying the motor module 1 and the cyclone separation module 2 The 31 can be conveniently supported on the dust collecting container 33 at the time of use, and the dust collecting container 33 can be easily taken away when the dust in the dust collecting container 33 needs to be drained. Therefore, the cyclone cleaner is easy to use. Further, the dust collecting container 33 may be a container existing in the user's home, and may be placed under the seat plate 31 only when in use. In this way, when transporting or carrying the cyclone vacuum cleaner, the dust collecting container can be omitted, which greatly facilitates the transportation or carrying of the cyclone vacuum cleaner.
