[0002] A floor scrubber is a device used to clean floor surfaces, commonly used in commercial and domestic environments. They typically use water and detergent to clean floors, and remove dirt, dust and other debris through devices such as brushes, rags or vacuum cleaners. Floor scrubbers can work in a variety of ways, including manual push, electric or automated. In a domestic environment, small floor scrubbers are often used to clean hard floors in the home, such as wooden floors, tile floors, etc.

[0003] In daily use, household floor scrubbers need to be used with a power-assisting mechanism to reduce the operator's physical exertion. However, the existing power-assisting wheel structure is relatively simple and generally does not have a power mechanism. The general structure of the power mechanism is also relatively complex, which affects the user experience. Utility Model Content

A hinge head is arranged in the hollow groove, and one end of the hinge head is connected to the base and the other end is hinged to the hinge member.

[0009] A further improvement to the above solution is that the base is arranged at the bottom of the empty slot and connects the two opposite connecting plates.

[0010] A further improvement to the above scheme is that two power-boosting wheels are provided, the two power-boosting wheels are respectively arranged on the outer side surfaces of the two connecting plates, and at least one of the two power-boosting wheels has a built-in driving element.

[0011] A further improvement to the above scheme is that the driving element is an outer rotor direct drive motor, the power-assisted wheel is provided with a tire, and the inner diameter of the tire is sleeved on the rotor housing of the outer rotor direct drive motor.

The built-in driving element is used for the power-assisting wheel, which is easy to operate.

[0017] The power-assisted wheel of the floor scrubber has a built-in driving element. When the connecting rod pushes the base to move, the power-assisted wheel can provide additional power, thereby reducing the burden on the operator and improving operating efficiency. The setting of the connecting frame and the connecting rod makes the entire power-assisted mechanism on the floor scrubber have better flexibility and stability, which can adapt to the cleaning needs of different floors and maintain the stable operation of the cleaning equipment. The design of the power-assisted wheel can reduce the physical exertion of the operator to a certain extent, thereby saving human resources and improving the working efficiency of the floor scrubber. The design of the power-assisted mechanism enables the floor scrubber to move more efficiently and accurately during the cleaning process, thereby improving the cleaning effect and cleaning speed.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] like Figure 1 to Figure 5As shown, in one embodiment of the utility model, a single-drive power-assisting mechanism is involved, including a base 1, a connecting frame 2, a connecting rod 3 and a power-assisting wheel 4. The connecting frame 2 is arranged on one side of the base 1, and a connecting groove 23 is arranged on the connecting frame 2. The connecting rod 3 is provided with a hinge 31, and one end of the hinge 31 is hinged to the connecting frame 2 with the connecting groove 23. The power-assisting wheel 4 is arranged on the base 1 or the connecting frame 2, and the power-assisting wheel 4 is built with a driving element 41 for providing power assistance when the connecting rod 3 pushes the base 1 to move. This embodiment is used for power assistance when household appliances are used. When the connecting rod 3 pushes the base 1 to move, the driving element 41 in the power-assisting wheel 4 is started, driving the power-assisting wheel 4 to rotate to provide power assistance, saving the consumption of driving force during use, and being easy to use. The problem that the existing power-assisting wheel 4 needs to be external and the dual-drive structure is complicated is solved, and the built-in driving element 41 is used for the power-assisting wheel 4, which is easy to operate.

[0029] In the above embodiment, the power-assisting wheel 4 has a built-in driving element 41. When the connecting rod 3 pushes the base 1 to move, the power-assisting wheel 4 can provide additional power, thereby reducing the burden on the operator and improving the operating efficiency.

[0030] In the above embodiment, the arrangement of the connecting frame 2 and the connecting rod 3 enables the entire power-assisting mechanism on the floor scrubber to have good flexibility and stability, can adapt to the cleaning requirements of different floors, and maintain the stable operation of the cleaning equipment.

[0031] In the above embodiment, the design of the power-assisted wheel 4 can reduce the physical exertion of the operator to a certain extent, thereby saving human resources and improving the working efficiency of the floor scrubber.

[0032] In the above embodiments, the design of the power-assisting mechanism enables the floor scrubber to move more efficiently and accurately during the cleaning process, thereby improving the cleaning effect and cleaning speed.

[0033] The base 1 is provided with a booster frame 11 below the connecting frame 2, and the booster wheel 4 is installed on the booster frame 11. The setting of the booster frame 11 can increase the stability of the floor scrubber, make it more stable during operation, reduce vibration, and improve the cleaning effect. The booster wheel 4 is installed on the booster frame 11, which can reduce the operator's effort to push the floor scrubber by providing additional assistance, thereby reducing the labor intensity of the operation. The installation position of the booster wheel 4 and the design of the booster frame 11 can improve the flexibility and maneuverability of the floor scrubber, making it easier to operate and adapt to the needs of different cleaning environments. In this embodiment, a single booster wheel 4 is used in combination with an internal drive, and the booster frame 11 is set in the middle position of the base 1. By using this booster structure on the floor scrubber, the efficiency of the cleaning operation can be improved, the fatigue of the operator can be reduced, thereby improving work efficiency and cleaning quality.

[0034] The base 1 has a bottom bracket 12 extending toward the bottom of the connecting groove 23, and the bottom bracket 12 is provided with auxiliary wheels 13. In this embodiment, the arrangement of the bottom bracket 12 and the auxiliary wheels 13 can increase the stability of the floor scrubber, especially on uneven ground, the auxiliary wheels 13 can help disperse the weight and provide additional support, reducing the possibility of the machine shaking and tilting. The arrangement of the auxiliary wheels 13 makes the floor scrubber more flexible and convenient when it needs to be moved or turned, and the operator can easily push and control the floor scrubber, improving the operating efficiency. Through the design of the bottom bracket 12 and the auxiliary wheels 13, the operator will feel more stable and comfortable when moving and controlling the floor scrubber, reducing the labor intensity of the operation and improving the operating experience.

[0035] See also Figure 2-3 As shown, the connecting frame 2 includes two groups of connecting plates 21 arranged opposite to each other, and an empty slot is formed between the two connecting plates 21. A hinged joint 22 is arranged in the empty slot, and one end of the hinged joint 22 is connected to the base 1, and the other end is hinged to the hinge 31. In this embodiment, by setting two groups of connecting plates 21 and hinged joints 22, the stability of the connecting frame 2 can be increased, ensuring that the connecting frame 2 remains stable when the floor scrubber is working, and reducing the possibility of loosening and vibration. The design of the connecting plates 21 and the hinged joints 22 makes the connecting frame 2 flexible to a certain extent, and can adapt to the needs of different working scenarios, and is also convenient for adjustment to meet specific working requirements. Due to the reasonable design of the structure of the connecting frame 2, the maintenance of the floor scrubber may be more convenient, such as easier operation when replacing parts or performing daily maintenance.

[0036] The bottom bracket 12 is arranged at the bottom of the empty slot and connects the two opposite connecting plates 21. In this embodiment, the bottom bracket 12 serves as a connecting intermediate piece of the connecting plate 21, which can increase the stability of the connecting frame 2, ensure that the connecting frame 2 remains stable when the floor scrubber is working, and reduce the possibility of loosening and vibration. The arrangement of the bottom bracket 12 helps to provide balanced support for the connecting plate 21, thereby improving the overall stability and operational safety of the floor scrubber.

[0037] There are two power-boosting wheels 4, which are respectively arranged on the outer sides of the two connecting plates 21, and at least one of the two power-boosting wheels 4 is equipped with a driving element 41. In this embodiment, the arrangement of the power-boosting wheel 4 makes the floor scrubber more flexible and easy to operate when moving and turning, especially in narrow spaces or scenarios where frequent turning is required, which can improve the operating efficiency. The power-boosting wheel 4 with a built-in driving element 41 can provide additional traction and driving force, which helps the floor scrubber to move and operate on different surfaces. The application of the design of at least one built-in driving element 41 on the outside of the connecting plate 21 to the floor scrubber may bring technical effects such as flexibility, enhanced driving force, reduced labor intensity of operators and improved machine stability, which is beneficial to improving the performance and operating convenience of the floor scrubber. Further, the structural cost can also be saved.

[0038] The driving element 41 is an outer rotor direct drive motor, and the power-assisted wheel 4 is provided with a tire 42, and the inner diameter of the tire 42 is sleeved on the rotor housing of the outer rotor direct drive motor. In this embodiment, the outer rotor direct drive motor is used as the driving element 41 to directly drive the power-assisted wheel 4, which reduces the transmission link, improves the transmission efficiency, and also reduces energy loss. The provision of the tire 42 helps to increase the friction between the power-assisted wheel 4 and the ground, providing greater traction, thereby enhancing the mobility of the floor scrubber on different ground surfaces. Among them, the driving element 41 can also be in the form of a brushed motor combined with a reducer.

[0039] The outer diameter of the tire 42 is provided with an anti-skid pattern 421, and the anti-skid pattern 421 is provided with a drainage groove, and the drainage groove is continuously arranged in an "eight" shape on the anti-skid pattern 421. In this embodiment, the provision of the anti-skid pattern 421 can increase the contact between the tire 42 and the ground, improve the grip and anti-skid performance, especially on wet or uneven ground, which helps to improve the driving stability and safety of the floor scrubber. The "eight" shape design of the drainage groove can effectively disperse and discharge water, reduce the impact of accumulated water on the grip of the tire 42, improve the drainage performance of the tire 42, and help maintain good grip performance in a humid or rainy environment.

[0040] See also Figure 4-5 As shown, a floor scrubber includes a single-drive power-assisting mechanism. The use of the power-assisting mechanism on the floor scrubber can provide a more efficient and stable cleaning operation experience and reduce the burden on the operator.

[0041] The floor scrubber includes a cleaning head 5 and a gripping handle 6, wherein the cleaning head 5 is arranged on a base 1, and the gripping handle 6 is arranged on a connecting rod 3. In this embodiment, the cleaning head 5 is arranged on the base 1, which can make the floor scrubber more stable during operation, and also facilitate the contact between the cleaning head 5 and the ground, thereby improving the cleaning effect. The gripping handle 6 is arranged on the connecting rod 3, which is conducive to the operator holding and controlling the moving direction and speed of the floor scrubber, thereby improving the comfort and convenience of operation.
