Description

Technical Field

[0001] The invention relates to the technical field of portable fan components, in particular to a fan component and a portable vacuum cleaner. Background Art

[0002] After many years of development, vacuum cleaners such as horizontal vacuum cleaners, handheld vacuum cleaners, car-mounted vacuum cleaners, floor scrubbers, fabric cleaning machines, etc. are relatively popular. The vacuum cleaner is provided with suction by a fan, and the large amount of airflow inhaled brings the dirt into the dust bin or sewage bin. This is the basic working principle.

[0003] In the prior art, vacuum cleaners are generally cylindrical, especially in the field of portable vacuum cleaners, such as car-mounted vacuum cleaners, handheld vacuum cleaners, etc., which are all cylindrical. Therefore, the fan and the control unit generally have sufficient installation space, and the volume of the fan and the control unit is not the key consideration for reducing the volume of the vacuum cleaner.

[0004] The applicant will propose a new type of fan assembly in this application, which integrates the fan and the control unit to achieve a smaller thickness. The applicant will also propose a portable vacuum cleaner using the aforementioned fan assembly. Summary of the invention

[0008] The present disclosure proposes a new technical route, in which the fan and the control unit are integrated, and the user operation side of the control unit is facing away from the fan to face outward to provide a user-operable part, and since the control unit is extended along the axial direction of the fan and connected to the circumference of the fan, there is a direction in the radial direction of the fan in which the fan and the control unit overlap. If the direction intersecting with the overlapping direction is taken as the thickness direction, a smaller thickness can be obtained, and the direction perpendicular to the overlapping direction is the minimum thickness direction of the fan assembly. Therefore, the present disclosure can make the fan and the control unit at least partially overlap in the height direction, thereby reducing the thickness dimension and reducing the overall thickness of the fan assembly. Since the control unit is connected to the fan, there is no wasted space between the control unit and the fan, thereby further reducing the size.

DETAILED DESCRIPTION

[0036] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0037] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0038] like Figures 1 to 5 The figure shows a fan assembly, including a fan 1 and a control unit 3. The control unit 3 is arranged to extend along the axial direction of the fan 1 and is connected to the circumference of the fan 1. The user-operated side of the control unit 3 faces away from the fan 1 and toward the outside.

[0039] like Figure 2 As shown, the overlapping direction forms an angle with the thickness direction. When the angle reaches a certain value, along the thickness direction, the control unit 3 will completely overlap with the fan 1 in the radial direction, or in the direction perpendicular to the thickness direction. Figure 2As shown, since the size of the control part 3 is small, the included angle does not need to be a right angle to enable the control part 3 to completely overlap with the fan 1 in the direction perpendicular to the thickness direction.

[0040] like Figure 1 , 4 As shown, the fan 1 includes a fan cover 7, and the housing 4 of the control unit 3 is connected to the fan cover 7. This design is conducive to a compact structure.

[0041] like Figure 5 As shown, the fan cover 7 is integrally arranged with the housing 4 of the control unit 3. This simplifies production and assembly and is conducive to reducing the size.

[0042] The fan cover 7 is sleeve-connected with the air extraction end 2 of the fan 1 to fix the housing 4 of the control unit 3 in the circumferential direction of the fan 1. This simplifies production and assembly and is conducive to reducing the size.

[0043] like Figure 4 , 5 As shown, the housing 4 is provided with a mounting cavity 14 extending along the axial direction of the fan 1 , a circuit board 12 is arranged in the mounting cavity 14 , and a switch 13 is arranged on the user operation side of the circuit board 12 .

[0044] The circuit board 12 is connected to a cable 6 , and the cable 6 is electrically connected to the circuits of the battery 22 , the fan 1 , etc., so that the control unit 3 can realize functions such as power on / off and speed regulation.

[0045] like Figure 1 As shown, it also includes a switch panel 5, which is movably matched with the opening of the housing 4. This design is conducive to the switch panel 5 being flush with the opening of the housing 4 or lower than the opening of the housing 4, thereby helping to reduce the thickness.

[0046] In this example, there are two switches 13, corresponding to the on / off switch and the speed control, respectively. The switch panel 5 can be two pieces or one piece. When it is one piece, for example, Fig.12 , 13 The seesaw switch panel 5 shown has a more compact structure and is more convenient to assemble.

[0047] like Figures 6 to 11 The figure shows a portable vacuum cleaner, comprising a cleaning element 15, a shell and a dust bin, and also comprising the fan assembly, wherein the fan assembly is installed in a space defined by the shell along a thickness direction 10, and the control unit 3 and the fan 1 are at least partially overlapped in a direction perpendicular to the thickness, and the user operation side of the control unit 3 is located on the surface of the shell; the fan assembly sucks the dirt on the surface cleaned by the cleaning element 15 into the dust bin.

[0048] In this example, in order to make the switch panel 5 located on the surface of the housing in the thickness direction, it can be the front cover 19 or the rear cover 20, for example, lower than the surface, level with the surface or higher than the surface, so that the control unit 3 and the fan 1 have a partial overlap in the direction perpendicular to the thickness, thereby controlling the thickness size and also realizing the setting of the switch panel 5, that is, the position setting of the user operation side of the control unit 3. In the following, the switch panel 5 is located on the front cover 19 as an example, so as not to affect the setting of the accommodating groove 24. In addition, by setting the switch panel 5 on the front cover 19 or the rear cover 20, a larger area of ​​the switch panel 5 can be set, so that the user can operate it easily.

[0049] In this example, if Fig. 9 As shown, the axial direction of the fan 1 of the fan assembly is perpendicularly arranged to intersect with the thickness direction 10 of the housing, thereby facilitating obtaining a minimum thickness.

[0050] In this example, if Figure 6 , 7 As shown in , 8, the housing adopts a block housing, and the block housing includes a circumferential portion, a front portion and a rear portion, which enclose a block installation space, and the dust bin, the fan assembly and the battery 22 are all installed in the block installation space, and the dust bin, the fan assembly and the battery 22 do not overlap each other in the thickness direction 10 of the block housing, but are distributed in the same plane defined by the block installation space. Therefore, compared with the vacuum cleaners in the prior art, the vacuum cleaner disclosed in the present invention is in a flat block shape as a whole, which the applicant defines as a Cube design, that is, a square design, which has the characteristics of being thin and square.

[0051] Of course, it can also be a block of other shapes, such as a trapezoidal block, a regular pentagonal block, a circular block, etc., but no matter what shape it is, the dust bin, the fan assembly and the battery 22 in the present disclosure do not overlap with each other in the thickness direction of the block shell, but are distributed in the same plane defined by the block installation space. If the thickness direction of the block shell is defined as the longitudinal direction, and the direction perpendicular to the thickness direction is the transverse direction, then the dust bin, the fan assembly and the battery 22 do not overlap with each other in the thickness direction of the block shell, but are distributed in the same plane defined by the block installation space, that is, the dust bin, the fan assembly and the battery 22 are distributed in the transverse space of the block installation space, but do not overlap in the longitudinal direction.

[0052] In some embodiments, the block-shaped installation space is provided with an installation slot 30, and the battery 22 is detachably connected to the installation slot 30. The installation slot 30 is provided with an opening on one side of the rear portion, and batteries 22 of different thicknesses can be higher than the rear surface through the opening; or, the installation slot 30 is provided with an opening on one side of the front portion, and batteries 22 of different thicknesses can be higher than the front surface through the opening. This is advantageous in that, in the case of a thin and square design, vacuum cleaners with different battery life can be provided according to different users, that is, compatibility is improved, and batteries 22 of different thicknesses purchased by users are all compatible with the vacuum cleaner disclosed herein.

[0053] In some embodiments, the block-shaped shell includes a middle frame 23, a front cover 19 and a rear cover 20. The middle frame 23, the front cover 19 and the rear cover 20 are connected along the thickness direction 10 of the block-shaped shell to form a block-shaped installation space. The middle frame 23 is integrally provided with a mounting slot 30 for the battery 22, a dust bin body 26 and a accommodating interval 25 that is arranged through the thickness direction. The mounting slot 30 is used to install the battery 22, and the accommodating interval 25 is used to install the fan assembly, so that the fan assembly is clamped between the front cover 19 and the rear cover 20 to obtain a smaller thickness dimension. The dust bin body 26 is provided with an opening on one side of the front cover 19 or the rear cover 20, and a cover plate 18 that can open / close the opening is provided on the front cover 19 or the rear cover 20. An air outlet 27 is provided on the back of the dust bin body 26, and a duct body 28 is also provided on the back of the dust bin body 26. The duct body 28 extends all the way to the side of the accommodating interval 25 of the fan assembly and is provided with an air inlet 29.

[0054] As described above, in order to facilitate production and manufacturing, improve production and manufacturing efficiency, and reduce production and manufacturing costs, the block shell is further improved to include a middle frame 23, a front cover 19 and a rear cover 20, wherein the middle frame 23 provides the circumferential portion, the front cover 19 provides the front portion, and the rear cover 20 provides the rear portion, and the middle frame 23, the front cover 19 and the rear cover 20 are connected along the thickness direction of the block shell to form a block installation space.

[0055] In addition, in order to further improve compactness and reduce size, such as Fig.10 , 11As shown, the middle frame 3 is integrally provided with a mounting groove 30, a dust bin body 26 and a receiving space 25 arranged in sequence in the circumferential direction. The mounting groove 30 is provided with a battery 7, and the receiving space 25 is provided with a fan assembly. The dust bin body 26 is provided with an opening on one side of the front cover 19 or the rear cover 20, and a cover plate 13 that can open / close the opening is provided on the front cover 19 or the rear cover 20. An air outlet 27 is provided on the back of the dust bin body 26, and an air duct body 28 is also provided on the back of the dust bin body 26. The air duct body 28 extends all the way to one side of the receiving space 25 and is provided with an air inlet 29. The fan cover 7 is provided with a connecting joint 8 to connect the air inlet 29. The air duct body 28 is closed by a sealing plate located on the back of the dust bin body 26. The sealing plate can be an independent part or a wall surface on the rear cover 20. After such a design, there is no need to separately manufacture the main parts such as the mounting groove 30, the dust bin body 26, and the receiving space 25, which significantly reduces the number of molds, reduces production costs, and improves production efficiency. The middle frame 3 can be integrally manufactured using a plastic molding process.

[0056] like Fig. 9 , 10 As shown in Figures 11, the middle frame 23 is also provided with a receiving groove 24, which is arranged around the middle frame 23, and a connecting port 17 is provided on the middle frame 23. The receiving groove 24 can accommodate a connecting pipe 16, one end of the connecting pipe 16 is connected to the connecting port 17, and the other end of the connecting pipe 16 is connected to the cleaning member 15.

[0057] To facilitate hanging or fixing, a back clip 21 is also included. In this example, Figure 7 As shown, the back clip 21 is disposed on the back cover 20 .
