Description

Technical Field

[0001] This utility model belongs to the field of dust removal technology, specifically providing a base station for a vacuum cleaner. Background Technology

[0002] A vacuum cleaner base station is an accessory device for vacuum cleaners, primarily providing charging, cleaning assistance, and functional expansion support. It is a core component that enhances the ease of use of vacuum cleaners. When placing the vacuum cleaner on the base station, users typically insert the vacuum cleaner into it, allowing it to hang on one side of the base station.

[0003] For aesthetic reasons, users usually place base stations against a wall or in a corner, with the back of the base station facing the wall. The product design also takes aesthetics into consideration, usually placing the vacuum cleaner mount on the back of the base station, which enhances the base station's appearance.

[0004] However, when users hang a vacuum cleaner on the base station, they need to manually hold the vacuum cleaner and rotate it 180° before putting it in, and their hands need to go around the base station, which is inconvenient. Utility Model Content

[0005] One objective of this invention is to solve the problem that base stations cannot simultaneously achieve both aesthetics and convenience.

[0006] To achieve the above objectives, this utility model provides a base station for a vacuum cleaner, comprising:

[0007] The main body is used to fix the vacuum cleaner;

[0008] A base is disposed at the bottom of the main body and is rotatably connected to the main body so that the vacuum cleaner fixed to the base station can rotate relative to the base station;

[0009] A drive device for driving the main body to rotate.

[0010] Optionally, the driving device includes:

[0011] The motor is fixedly connected to the base;

[0012] The drive gear is driven by the output shaft of the motor.

[0013] The driven gear meshes with the driving gear and is fixedly connected to or integrally formed with the main body.

[0014] Optionally, the base is provided with an upward-facing recess and a slot, the recess and the slot being connected, the recess being used to accommodate at least a portion of the driven gear, and the slot being used to accommodate at least a portion of the driving gear.

[0015] Optionally, the drive gear is coaxially and fixedly connected to the output shaft of the motor.

[0016] Optionally, the base station further includes a plurality of rollers and a cage;

[0017] The plurality of rollers are disposed between the driven gear and the base so that the driven gear and the base make rolling contact through the rollers;

[0018] The cage is used to limit the distance between two adjacent rollers.

[0019] Optionally, the rollers and the cage are fitted into the sink.

[0020] Optionally, the base is provided with a rotating shaft in the sink, and the retainer is provided with a shaft hole adapted to the rotating shaft so that the rotating shaft passes through the shaft hole and prevents the retainer from moving radially.

[0021] Optionally, the base is further provided with an upwardly protruding annular boss in the sink groove, so that the base can make rolling contact with the roller through the annular boss.

[0022] Optionally, the base station further includes an annular member fixedly connected to the driven gear. The annular member is provided with an annular groove with an opening facing downward, so that the roller is embedded in the annular groove and rolls in contact with the top wall of the annular groove to prevent the driven gear from moving radially relative to the base.

[0023] Optionally, the driven gear has a downward-facing slot on its bottom side, and the annular member is embedded in the slot; and / or the driven gear has a downward-extending insertion shaft on its bottom side; one of the rotating shaft and the insertion shaft of the base is hollow, so that the rotating shaft and the insertion shaft are rotatably connected together.

[0024] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, by making the base rotatably connected to the main body, the vacuum cleaner fixed to the base station can be driven by the drive device to rotate relative to the base station. This allows the user to automatically rotate the back of the base station to the user's side when the user needs to put the vacuum cleaner into the base station, and automatically rotate the back of the base station to the side away from the user after the vacuum cleaner is placed in the base station. This improves the user's convenience while also taking into account the aesthetics of the base station.

[0025] Furthermore, by fixing the motor to the base and driving the drive gear to the output shaft of the motor, and fixing or integrating the driven gear to the main body and meshing it with the drive gear, the base station can automatically drive the main body to rotate, further improving the user's convenience.

[0026] Furthermore, by providing an upward-facing and interconnected recess and slot on the base, the recess accommodates at least a portion of the driven gear, and the slot accommodates at least a portion of the driving gear, thereby allowing the driving gear and driven gear to be embedded inside the base, thus avoiding the drive device occupying too much space.

[0027] Furthermore, by placing multiple rollers between the driven gear and the base, the driven gear and the base can make rolling contact through the rollers, reducing rotational resistance and improving operational smoothness. At the same time, the cage limits the distance between adjacent rollers, preventing roller misalignment or stacking, ensuring stable rotation, and effectively preventing jamming.

[0028] Furthermore, by embedding the rollers and cage in the grooves of the base, the rollers and cage are prevented from disengaging from the contact area between the driven gear and the base, thus improving structural stability.

[0029] Furthermore, by setting a rotating shaft in the settling tank and simultaneously setting a corresponding shaft hole on the cage that matches the rotating shaft, and allowing the rotating shaft to pass through the shaft hole, the cage is prevented from moving radially, thus further ensuring the stability of the roller position.

[0030] Furthermore, by providing an annular member fixedly connected to the driven gear and providing an annular groove with a downward opening on it, the roller is embedded in the annular groove and rolls in contact with the top wall of the annular groove, thus preventing the driven gear from moving radially relative to the base.

[0046] Those skilled in the art should understand that the embodiments described below are merely some embodiments of the present invention, and not all embodiments of the present invention. These embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0047] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "top," "bottom," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0048] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. For example, unless otherwise specified, the terms "installation," "connection," "joining," and "fixing" can specifically refer to any feasible connection form such as bolt connection, screw connection, welding, insertion, riveting, fusion welding, or snap-fit.

[0049] like Figure 1 As shown, base station 001 includes a main body 100, a base 200, and a drive device 600. The main body 100 is used to fix a vacuum cleaner 002. The base 200 is disposed at the bottom of the main body 100 and rotatably connected to the main body 100, allowing the vacuum cleaner 002 fixed to the base station 001 to rotate relative to the base station 001. The drive device 600 is used to drive the main body to rotate.

[0050] Those skilled in the art will understand that by rotatably connecting the base 200 to the main body 100, the vacuum cleaner 002 fixed to the base station 001 can rotate relative to the base station 001. Thus, when the user needs to put the vacuum cleaner 002 into the base station 001, the back of the base station 001 can be rotated to the user's side. After the vacuum cleaner 002 is placed into the base station 001, the user can rotate the back of the base station 001 to the side away from the user, ensuring that the user can use the vacuum cleaner while also taking into account the aesthetics of the base station 001.

[0051] In this context, the "back" of base station 001 refers to the side where vacuum cleaner 002 is located after it is placed inside base station 001. Because base station 001 is usually placed against a wall or in a corner, for aesthetic reasons, the side of base station 001 where vacuum cleaner 002 is mounted usually faces the wall, i.e., away from the user. Therefore, the side of base station 001 where vacuum cleaner 002 is mounted is referred to as the "back" of base station 001.

[0052] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the drive device 600 includes a motor 610, a drive gear 620, and a driven gear 630. The motor 610 is fixedly connected to the base 200, the drive gear 620 is drivenly connected to the output shaft of the motor 610, and the driven gear 630 meshes with the drive gear 620 and is fixedly connected to or integrally formed with the main body 100.

[0053] In this embodiment, the base station 001 can electrically drive the main body 100 to rotate through the combination of the motor 610, the driving gear 620, and the driven gear 630, without the user needing to apply manual force. Especially for the base station 001 placed in a corner or next to furniture, the user only needs to trigger the drive device 600 to automatically turn the fixed area of ​​the vacuum cleaner 002 toward themselves, avoiding the space limitations that may occur when rotating manually.

[0054] In addition, manually turning the main body of the base station can be quite strenuous for large or heavy vacuum cleaners. The addition of the drive unit 600 reduces the physical burden on users, making it easy for vulnerable groups such as the elderly and children to operate, further improving the product's applicability.

[0055] In some embodiments of this utility model, the motor 610 can be a stepper motor, and the drive device 600 can precisely control the rotation angle of the main body 100 by the forward and reverse rotation of the stepper motor, so as to ensure that the vacuum cleaner 002 can accurately reset after each rotation.

[0056] Continue reading Figure 3 and Figure 4 In some embodiments of this utility model, the base 200 is provided with an upward-facing recess 210 and a slot 240. The recess 210 and the slot 240 are connected. The recess 210 is used to accommodate at least a portion of the driven gear 630, and the slot 240 is used to accommodate at least a portion of the driving gear 620. The design of the recess 210 and the slot 240 allows the driving gear 620 and the driven gear 630 to be embedded inside the base 200, effectively utilizing space and reducing the volume occupied by the drive device 600.

[0057] like Figure 4 As shown, in some embodiments of this utility model, the drive gear 620 is coaxially and fixedly connected to the output shaft of the motor 610.

[0058] like Figure 1 As shown, base station 001 has a dust collection chamber, an opening for connecting to vacuum cleaner 002, and a connecting channel between the opening and the dust collection chamber. Vacuum cleaner 002 connects to the opening of base station 001, allowing foreign objects in vacuum cleaner 002 to sequentially enter the dust collection chamber through the opening and the connecting channel. A filter device is located at the bottom of the dust collection chamber, and a fan is installed below the filter device to suck foreign objects from vacuum cleaner 002 into the dust collection chamber.

[0059] like Figures 2 to 4As shown, in some embodiments of this utility model, the base station 001 further includes a plurality of rollers 300 and a retainer 400. The plurality of rollers 300 are disposed between the driven gear 630 and the base 200, so that the driven gear 630 and the base 200 make rolling contact through the rollers 300. The rollers 300 convert the sliding friction between the driven gear 630 and the base 200 into rolling friction, reducing rotational resistance and improving operational smoothness. The retainer 400 is used to limit the distance between two adjacent rollers 300, maintain the orderly arrangement of the rollers 300, prevent the rollers 300 from shifting or stacking, ensure stable rotation, and prevent jamming.

[0060] like Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the roller 300 and the cage 400 are embedded in the recess 210. The recess 210 provides installation space for the roller 300 and the cage 400, achieving a compact structure and avoiding exposed parts that affect aesthetics. At the same time, physical limiting prevents the roller 300 and the cage 400 from disengaging from the contact area between the driven gear 630 and the base 200, thereby improving structural stability.

[0061] Continue reading Figure 2 and Figure 4 In some embodiments of this utility model, the base 200 is provided with a rotating shaft 220 in the recess 210, and the retainer 400 is provided with a shaft hole 410 adapted to the rotating shaft 220 so that the rotating shaft 220 passes through the shaft hole 410, preventing the retainer 400 from moving radially, avoiding the retainer 400 from deviating from the center when rotating, further ensuring the stability of the roller 300 position, and strengthening the concentricity of the rotation process in conjunction with the retainer 400.

[0062] Continue reading Figure 2 and Figure 4 In some embodiments of this utility model, the base 200 is further provided with an upwardly protruding annular boss 230 in the recess 210, so that the base 200 can roll in contact with the roller 300 through the annular boss 230. The annular boss 230 can be made of metal material so that the annular boss 230 has sufficient strength to support the roller 300.

[0063] Continue reading Figure 2 and Figure 4In some embodiments of this utility model, the base station 001 further includes an annular member 500 fixedly connected to the driven gear 630. The annular member 500 is provided with an annular groove 510 with its opening facing downward, so that the roller 300 is embedded in the annular groove 510 and rolls in contact with the top wall of the annular groove 510 to prevent the driven gear 630 from moving radially relative to the base 200. The annular member 500 can be made of metal material. The metal annular member 500 can ensure the long-term stability of the shape accuracy of the annular groove 510. Even if the roller 300 is subjected to continuous pressure due to tilting or long-term rolling, the contour of the annular groove 510 is not easily changed, avoiding the roller 300 from getting stuck or the radial limit failure due to groove deformation.

[0064] Those skilled in the art will understand that the annular groove 510 encloses the roller 300 and makes it contact the top wall, restricting the radial movement of the roller 300 from the driven gear 630 side. Together with the rotating shaft 220 and the annular boss 230 of the base 200, it forms a bidirectional radial limit, completely preventing the driven gear 630 from radially offset or wobbling relative to the base 200. At the same time, the annular member 500 is fixed to the driven gear 630, strengthening the connection strength between the driven gear 630 and the base 200, and ensuring that the two always maintain a corresponding positional relationship when rotating.

[0065] In some embodiments of this utility model, the driven gear 630 has a downward-facing slot 110 on its bottom side, and the annular member 500 is embedded in the slot 110. The slot 110 provides a fixing point for the annular member 500, realizing a stable connection between the annular member 500 and the driven gear 630, preventing the annular member 500 from loosening during rotation, and ensuring the reliability of its radial limiting function.

[0066] like Figure 2 As shown, in some embodiments of this utility model, a downwardly extending insertion shaft 120 is provided on the bottom side of the driven gear 630; one of the rotating shaft 220 and the insertion shaft 120 of the base 200 is hollow, so that the rotating shaft 220 and the insertion shaft 120 are rotatably connected together. That is, either the rotating shaft 220 or the insertion shaft 120 can be a hollow structure.

[0067] Those skilled in the art will understand that the rotating shaft 220 and the plug shaft 120 form a rotatable central shaft structure, providing central support for the rotation of the driven gear 630 and the base 200, ensuring that the rotation is around a fixed axis and avoiding deviation or tilting during rotation; the hollow design reduces the use of materials, achieving lightweight without affecting the connection strength.

[0068] In some embodiments of this utility model, the ratio of the diameter of the movement trajectory of the roller 300 to the height of the base station 001 can be selected from any value from 0.12 to 0.34. For example, the ratio of the diameter of the movement trajectory of the roller 300 to the height of the base station 001 can be any feasible value such as 0.12, 0.15, 0.20, 0.30, and 0.34.

[0069] Furthermore, the ratio of the diameter of the trajectory of the roller 300 to the height of the base station 001 can be selected from any value between 0.16 and 0.29. For example, the ratio of the diameter of the trajectory of the roller 300 to the height of the base station 001 can be any feasible value such as 0.16, 0.18, 0.22, 0.25, and 0.29.

[0070] Those skilled in the art will understand that if the ratio of the diameter of the roller 300's trajectory to the height of the base station 001 is too large, it will increase the floor space occupied by the base 200; if the ratio is too small, it will affect the stability of the base station 001. In this embodiment, by setting the ratio of the diameter of the roller 300's trajectory to the height of the base station 001 between 0.12 and 0.34, a balance can be achieved between stability, compactness, and space utilization in the rotating structure.

[0071] In this utility model, by rotatably connecting the main body 100 and the base 200, the main body 100 and the vacuum cleaner 002 fixed thereon can rotate relative to the base 200, directly breaking the limitation of fixed orientation. Users can rotate the main body 100 to adjust the orientation as needed, improving the convenience of placing the vacuum cleaner 002. At the same time, after rotation, the back can be turned back to the wall side to maintain aesthetics, thus solving the technical problem that the base station 001 cannot balance aesthetics and convenience.

[0072] like Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the roller 300 can be tilted. By tilting the roller 300, automatic self-alignment is achieved. After tilting, a slight angular deviation between the driven gear 630 and the base 200 during rotation is allowed. For example, when the base station 001 is placed on uneven ground (such as tile joints or slight depressions), or when there is a slight coaxiality error in the installation of the base 200 and the driven gear 630, the tilt angle of the roller 300 can be adaptively adjusted to avoid jamming or increased local wear caused by rigid contact, thus improving the tolerance and adaptability of rotation.

[0073] Furthermore, the annular boss 230 and annular groove 510 originally ensured the concentricity of the driven gear 630 and the base 200 through bidirectional limiting. However, after the roller 300 is tilted, it allows for a slight offset between the contact point of the roller 300 and the boss and annular groove 510 without compromising the overall concentricity constraint. For example, when the driven gear 630 tilts slightly due to external force (such as a slight press when the user places the vacuum cleaner 002), the tilted roller 300 can adjust and disperse stress through the angle of the contact surface, avoiding excessive local stress that could cause wear on the boss or annular groove 510, thus extending the service life of the structure.

[0074] In addition, the hollow fit between the plug shaft 120 and the rotating shaft 220 provides central support, but in actual use, slight misalignment may occur due to assembly errors. The tilting setting of the roller 300 compensates for this coaxiality deviation through its own angle. During rotation, the tilting direction of the roller 300 automatically adapts to the slight misalignment of the central shaft, making the rotational force on the driven gear 630 and the base 200 more even, avoiding problems such as wear on one side of the roller 300 or fluctuating rotational resistance due to central shaft misalignment, and improving the smoothness of the rotation process.

[0075] The method of using the base station 001 of this utility model is as follows:

[0076] First, before using base station 001, it needs to be placed in a suitable location (such as a wall, corner, or other regularly planned area). At this time, the back of the main body 100 of base station 001 faces the wall, and the base 200 is stably in contact with the ground. When it is necessary to put the vacuum cleaner 002 back into base station 001, there is no need to move the overall position of base station 001. The drive device 600 is triggered, causing base station 001 to rotate the main body 100 in its own direction. Since the base 200 and the main body 100 are in rolling contact through the roller 300, and the metal ring component 500 and the roller 300 are stably matched, the rotation process is smooth and without jamming, and the back of the main body 100 (i.e., the fixed position of vacuum cleaner 002) can be easily rotated to the side facing the user.

[0077] Furthermore, align the vacuum cleaner 002 with the fixing structure (such as a buckle or slot) on the main body 100, and place it horizontally or insert it in the usual way. At this time, since the orientation of the main body 100 has been adjusted to a convenient operating angle, the hand does not need to go around the base station 001 or operate in a narrow space in the corner, making the placement process more convenient and effortless.

[0078] Finally, after the vacuum cleaner 002 is fixed, the drive device 600 is triggered to rotate the main body 100 in the opposite direction until the back of the main body 100 is facing the wall again or away from the user.

[0079] This utility model also provides a dust collection system 010, which includes any of the above-mentioned base stations 001 and vacuum cleaners 002.

[0080] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments. Without departing from the technical principles of this utility model, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this utility model will fall within the protection scope of this utility model.
