Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a manual and electric dual-purpose sweeper. Background Technology

[0002] Currently, sweeping machines are widely used in homes and various office spaces as common cleaning equipment.

[0003] Existing robotic vacuum cleaners are mainly divided into two categories: manual and electric. Manual robotic vacuum cleaners rely entirely on the user to push them for cleaning, resulting in laborious operation and low cleaning efficiency. While electric robotic vacuum cleaners can effectively reduce labor intensity, they typically rely on external power sources or built-in batteries. Their use is significantly limited in places without power, when the battery is depleted, or in confined spaces where access to a power source is difficult. Furthermore, some products on the market that attempt to combine both modes often use two relatively independent power systems simply superimposed, without an integrated transmission structure design. This leads to a complex overall structure, high cost, inconvenient mode switching, and problems such as long transmission paths, significant energy loss, and difficulty in efficiently coordinating power transmission between manual and electric modes.

[0004] Therefore, there is an urgent need in this field for a sweeper that can efficiently and smoothly switch between manual and electric modes based on a single transmission system, enabling it to flexibly select the power source according to the actual usage scenario, and combining ease of operation with environmental adaptability. Utility Model Content

[0005] The purpose of this utility model is to provide a manual and electric dual-mode sweeper to solve the problems of manual sweepers being laborious, electric sweepers being dependent on power sources, and the difficulty in efficiently integrating the two modes in the existing technology. The technical solution adopted by this utility model is as follows: a manual and electric dual-purpose sweeper, including a body and a sweeping component, a moving component, and a garbage collection part disposed on the body, and further including a power component, a push rod component, and a transmission system; the transmission system includes a first transmission mechanism, a second transmission mechanism, and a switching device; the switching device is disposed between the output end of the power component and the first transmission mechanism, for selectively engaging or disengaging the output end of the power component with the first transmission mechanism; the first transmission mechanism is drivenly connected to the sweeping component and the moving component respectively; the second transmission mechanism is drivenly connected to the sweeping component and the moving component respectively; the power component, the push rod component, and the transmission system are all mounted on the body. Furthermore, this application also proposes that the switching device be a clutch.

[0006] Furthermore, this application also proposes that the clutch is a planetary gear clutch.

[0007] Furthermore, this application also proposes that the power assembly includes a drive motor and a battery that supplies power to the drive motor.

[0008] Furthermore, this application also proposes that the moving component includes a first roller and a second roller disposed on both sides of the rear end of the body.

[0009] Furthermore, this application also proposes that the first transmission mechanism includes a driving gear and a driven gear that mesh with each other, the driving gear being connected to the output end of the switching device; and the driven gear being coaxially and fixedly connected to the axle of the first roller.

[0010] Furthermore, this application also proposes that the second transmission mechanism includes a transmission gear, which is coaxially and fixedly connected to the axle of the second roller.

[0011] Furthermore, this application also proposes that the cleaning assembly includes a roller brush and two disc brushes; the roller brush includes a drive shaft, one end of which is fixed with a first driven gear meshing with a driven gear, and the other end of which is fixed with a second driven gear meshing with a transmission gear; the two disc brushes are symmetrically arranged at the front of the machine body.

[0012] Furthermore, this application also proposes that pulleys are provided on both the driven gear and the transmission gear; the transmission system also includes a transmission belt, which is wound around the pulleys and the rotating seat of the disc brush.

[0013] Furthermore, this application also proposes that the push rod assembly is a U-shaped rod, with its two lower ends connected to the rear sides of the machine body.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] This embodiment provides an optimal implementation of a manual / electric dual-purpose sweeper, aiming to solve the problems of "manual sweepers being laborious, electric sweepers relying on power, and inefficient mode integration" in existing technologies. It achieves flexible switching between manual and electric modes through component collaborative design. Its detailed structure and working principle are as follows: See [link / reference] Figures 1-10 The manual / electric dual-purpose sweeper includes a body 1, a sweeping component 2, a moving component 3, a dust collection unit 4, a power component 5, a push rod component 6, and a transmission system 7. The moving component 3, the sweeping component 2, and the dust collection unit 4 are all integrated on the body 1. The power component 5, the push rod component 6, and the transmission system 7 are all installed on the corresponding positions of the body 1 through suitable fixing structures (such as bolt connections, bracket supports, buckle fixation, or one-piece molding connections), ensuring the stability of the whole machine structure and that all components work together to achieve the sweeping function.

[0019] The main body 1 is made of high-strength and lightweight materials (such as metal frame + plastic shell, engineering plastic or lightweight alloy), which not only meets the load-bearing requirements of each component installation (supporting the weight of power component 5 and cleaning component 2), but also takes into account the ease of manual pushing; the overall shape is designed according to the cleaning scene (such as narrow strip shape to suit corridors, rectangular shape to suit living room), providing reasonable layout space for each component (cleaning component 2 is arranged along the width of main body 1, and moving component 3 is symmetrically distributed on both sides).

[0020] The rear of the main body 1 has a reserved opening for the battery compartment, and a mode switching operation area is set near the push rod assembly 6 (such as next to the anti-slip grip in the middle of the push rod or on the outer shell at the hinge of the main body), which makes it convenient for users to switch operation modes and replace batteries, thus improving ease of use.

[0021] The moving component 3 includes a first roller 31 and a second roller 32, both of which are mounted on axle brackets at the bottom of the rear sides of the machine body 1 via bearings. The axle brackets are integrally formed or welded to the machine body 1 to ensure that the rollers rotate flexibly without shaking. The first roller 31 and the second roller 32 correspond to the independent axles of the first roller 31 and the second roller 32, respectively. The axle of the first roller 31 extends into the interior of the machine body 1 and is connected to the transmission system 7 for transmission, while the axle of the second roller 32 supports rotation.

[0022] The spacing between the first roller 31 and the second roller 32 is designed to be compatible. Together with the front cleaning component 2 supporting the ground, it can prevent the machine from tipping over when it is pushed forward, while reducing the frictional resistance of the ground and reducing the difficulty of manual pushing.

[0023] The cleaning component 2 includes a roller brush 21 and two disc brushes 22. The roller brush 21 is installed in the middle and rear of the machine body 1 through a bearing seat (close to the moving component 3 and with a reasonable gap). The surface is evenly distributed with nylon or mixed steel wire bristles, and the length matches the width of the machine body 1 to ensure that there are no dead corners in the cleaning. The two disc brushes 22 are vertically installed on both sides of the front of the machine body 1 through a rotating seat 221. The installation angle is optimized so that the garbage on both sides can be gathered towards the middle.

[0024] The drive shaft 211 of the roller brush 21 extends horizontally along the width direction of the body 1. One end is fixed with a first driven gear 212 and the other end is fixed with a second driven gear 213, which mesh with the driven gear 712 and the transmission gear 721 of the transmission system 7 respectively to realize power transmission.

[0025] The waste collection section 4 is an integrally formed receiving cavity inside the body 1, located between the disc brush 22 and the roller brush 21, and is set up to correspond to the waste collection path formed by the two. The top or side of the receiving cavity is equipped with an openable cover plate (connected by buckle or hinge) with sealing strips for easy cleaning of waste. The bottom is equipped with a drain hole with a filter screen to avoid water accumulation and waste blockage.

[0026] The power assembly 5 includes a drive motor 51 and a battery 52. ​​The drive motor 51 is fixed to the inner rear end of the body 1 by a bracket, and the output shaft is precisely connected to the transmission system 7. The battery 52 is a rechargeable lithium battery pack, which is embedded in the battery compartment at the rear of the body 1 and is connected to the drive motor 51 and the control circuit by wires. The outer layer of the wires is wrapped with an insulating sleeve.

[0027] The control circuit integrates an undervoltage protection module (automatic power-off when the voltage is too low) and an overload protection module (shutdown when the load exceeds the rated power); the battery compartment is equipped with a snap-on dust cover to extend the battery's lifespan.

[0028] The push rod assembly 6 has a U-shaped rod structure. The two lower ends are connected to the two sides of the rear end of the body 1 through hinges. The angle can be adjusted around the hinges to accommodate users of different heights. The middle of the push rod is fitted with a grip part with anti-slip texture to improve grip comfort and reduce fatigue from manual pushing.

[0029] The transmission system 7 includes a first transmission mechanism 71, a second transmission mechanism 72, and a switching device 73, and is the core of realizing mode switching and power transmission. Switching device 73: It adopts a planetary gear clutch (which can also be replaced by an electromagnetic clutch or a friction clutch), which is mounted on the output shaft of the drive motor 51 via a spline. The control end is electrically connected to the mode switching button, and the user can easily control its engagement or disengagement.

[0030] The first transmission mechanism 71 includes a driving gear 711 and a driven gear 712 that mesh with each other; the driving gear 711 is connected to the output end of the switching device 73, and the driven gear 712 is coaxially and fixedly connected to the wheel axle of the first roller 31, so as to realize the power transmission from the power component 5 to the moving component 3.

[0031] The second transmission mechanism 72 includes a transmission gear 721, which is coaxially and fixedly connected to the axle of the second roller 32; the first driven gear 212 and the second driven gear 213 at both ends of the drive shaft 211 of the roller brush 21 mesh with the driven gear 712 and the transmission gear 721 respectively, so as to realize the power transmission from the moving component 3 to the cleaning component 2.

[0032] Disc brush drive: Both the driven gear 712 and the transmission gear 721 are equipped with pulleys 74, and the transmission belt 75 is wound between the pulleys 74 and the rotating seat 221 of the disc brush 22; through the cross / co-rotation of the transmission belt 75, the two disc brushes 22 rotate in opposite directions, and the garbage on both sides is gathered towards the central roller brush 21.

[0033] Working mode description: Electric Mode: When the user turns on the power, the switching device 73 engages; the drive motor 51 outputs power, which is transmitted to the axle of the first roller 31 via the first transmission mechanism 71, driving the first roller 31 to rotate, which in turn drives the second roller 32 to move, and the whole machine moves forward automatically; at the same time, the power of the axle of the first roller 31 is transmitted to the roller brush 21 via the driven gear 712, and the axle of the second roller 32 is driven by the transmission gear 721 to assist in driving the roller brush 21 to rotate; the roller brush 21 drives the disc brush 22 to rotate in the opposite direction through the pulley 74 and the transmission belt 75, and the garbage is collected and swept into the garbage collection section 4 by the roller brush 21. The user only needs to control the direction of travel to achieve efficient cleaning.

[0034] Manual mode: When the battery 52 is low on power, the switching device 73 is disconnected, cutting off the motor power; the user pushes the push rod assembly 6 to make the whole machine move forward, and the ground friction forces the first roller 31 and the second roller 32 to rotate passively; the two roller axles drive the roller brush 21 to rotate through the driven gear 712 and the transmission gear 721 respectively, and the roller brush 21 then drives the disc brush 22 to work, realizing cleaning in the absence of power and improving the applicability of the equipment. Example

[0035] The overall structure, component connection relationship, and core functions of this embodiment are consistent with those of Embodiment 1. The main optimizations are to the transmission mechanism and switching device 73, adapting to noise-sensitive scenarios and convenient operation requirements: Both the first transmission mechanism 71 and the second transmission mechanism 72 use synchronous belt transmission instead of gear meshing. In the first transmission mechanism (71), the driving pulley is connected to the output end of the switching device 73, and the driven pulley is fixed to the axle of the first roller 31. The synchronous belt teeth mesh to avoid slippage. In the second transmission mechanism 72, the driving pulley is fixed to the axle of the second roller 32, and the driven pulley is connected to the drive shaft 211 of the roller brush 21. Both transmission mechanisms are equipped with spring bracket tensioning wheels to automatically compensate for the slack of the synchronous belt and ensure stable transmission. Synchronous belt transmission has lower noise and lower maintenance costs, making it suitable for home or office scenarios.

[0036] The switching device 73 adopts a combination of "electromagnetic clutch + rocker switch". The switch is located in the middle of the push rod assembly 6 and is marked with "electric / off / manual". When switched to "electric" position: the coil is energized, the clutch is engaged, and the power assembly 5 is connected to the transmission system 7; when switched to "manual" position: the coil is de-energized, the clutch is disengaged, and the power transmission is cut off.

[0037] This design simplifies the operation process, improves ease of use, and meets the requirement of "switching device controlling power engagement / disengagement" in the claims.

[0038] Work scenario: In electric mode, the synchronous belt drive reduces operating noise; in manual mode, a convenient switch allows for quick switching, and pushing the push rod drives the sweeping assembly 2. This embodiment retains the core advantages while further optimizing noise control and ease of operation, expanding the applicable scenarios for the equipment.
