Description

[0001] This application is a divisional application for the original application with application number 202010096704.9, the application date is September 18, 2016, the name of the invention is "Dual-drive mopping, polishing, and bottle washing device with self-balancing or self-compensating function", and the original application is a divisional application with application number 201610829582.3. Technical Field

[0002] The invention relates to the technical field of cleaning tools, and in particular to a double-driven mopping device with self-balancing or self-compensating functions. Background Art

[0003] In the prior art, drive devices are indispensable in many fields such as industry and life, but the existing drive devices, especially the drive devices, usually have the problem of displacement deflection during use, which brings many inconveniences to our work and life. Users need to overcome the displacement deflection force to work during the operation. If they are not careful, the spontaneous displacement of the drive device may also bring danger to our work and life. These are the shortcomings of the prior art.

[0004] A Chinese patent with patent publication number CN203370502U discloses a single-motor dual-axis drive device, the technical problem to be solved is "during the cooking and stirring process of the cooking pot, it is often necessary to have two sets of stirring devices stirring with the same or opposite directions. The existing driving devices all use two separate and independent driving devices to drive the two sets of stirring devices respectively, which requires two sets of frames, reduction gears, rotating shafts, motors, etc., with complex structures, large volumes, and inconvenient installation." It uses a set of dual-drive output stirring devices to achieve a compact structure and reduce volume, and there is no need to reduce or eliminate the difference in external counter-torque.

[0005] The patent publication number is CN102934968A - an electric steam mop. The technical problem to be solved is that the electric steam mop on the market is designed for larger commercial places. It is not suitable for home use due to its heavy and large size. The mop head is relatively high. When used at home, many places cannot be cleaned. The technical improvement is made. The disclosed solution is to drive the wiping mechanism on the mop head to move through the transmission mechanism in the connecting head, thereby reducing the size of the mop head, especially the height of the mop head. Such a design greatly reduces the size of the mop head, making the improved device relatively small and suitable for home use.

[0006] Although the above structure also has the effect of reducing the deflection force when the mop device is in use, it uses a non-concentric drive device. After long-term use, the drive device may further aggravate the displacement deflection phenomenon due to uneven force or wear. This will not only affect the uniformity and efficiency of mopping, but may also cause additional burden on the transmission mechanism and shorten the service life of the equipment. In addition, displacement deflection may also cause the connection between the electric system and the transmission mechanism to loosen, causing safety hazards. How to reliably solve the safety and reliability problems of mopping devices when in use has always been a technical problem that technicians in this field want to solve but have not been able to solve. Summary of the invention

[0007] Purpose of the invention:

[0008] In order to solve the problems existing in the above-mentioned prior art, the present invention is proposed.

[0009] Technical solution:

[0010] A self-balancing dual-drive mopping device comprises a motor and a dual-drive reducer, wherein the output device of the dual-drive reducer comprises a first output end and a second output end rotating in the opposite direction to the first output end, and the opposite deflection force generated by each driving end is offset by adjusting the speed ratio of the two driving ends, the inner shaft power output end of the dual-drive reducer serves as the first output end, and the outer shaft output end of the dual-drive reducer serves as the second output end, and device peripherals are arranged on the first output end and the second output end, the outer shaft is a hollow shaft, and the inner shaft can rotate in the opposite direction of the outer shaft coaxially;

[0011] During use, the motor is started and connected to the dual-drive reducer through the transmission mechanism. At the same time, the device peripherals arranged at the first output end and the device peripherals arranged at the second output end of the dual-drive reducer rotate in opposite directions. By adjusting the speed ratio of the inner and outer shafts of the dual-drive reducer, the device can be achieved in a balanced state during operation.

[0012] The first output end is proportional to the reversal speed of the second output end.

[0013] The motor is arranged above the reducer, and the housing of the motor is connected with the housing of the dual-drive reducer as a whole.

[0014] The self-balancing function described in the present invention refers only to the process in which the dual drive device is operated, in which the speed ratio of the two drive ends is adjusted to offset the opposite deflection force generated by each drive end, thereby achieving a stable and substantially non-deflection balanced working state. If the "self-balancing" defined in the present invention is the same as the "self-balancing" name used in other prior arts, the definition of the present invention shall prevail.

[0015] Advantages and effects: The present invention provides a self-balancing dual-drive mopping device, which transforms the traditional driving device to achieve a driving device without displacement deflection force when in use, while controlling the production cost to meet market needs, so that the present invention can be promoted and applied on a large scale.

[0023] Example 1

[0024] like Figure 1 As shown, this embodiment provides a dual-drive device with a self-balancing function, and the dual-drive device includes: a motor 1 and a dual-drive reducer 3, which are horizontally arranged; the motor 1 is connected to the dual-drive reducer 3 through a transmission mechanism such as belt drive, gear drive or chain drive; the output device used in this embodiment is the dual-drive reducer 3, the inner shaft power output end of the dual-drive reducer 3 is used as the first output end 4, and the outer shaft output end of the dual-drive reducer 3 is used as the second output end 5, the outer shaft is a hollow shaft, and the inner shaft can rotate in the outer shaft in the same direction as the axis.

[0025] When in use, the motor 1 is started and connected to the dual-drive reducer 3 through the transmission mechanism, and at the same time, the first output end 4 and the second output end 5 arranged on the dual-drive reducer 3 rotate in opposite directions at a certain ratio.

[0026] During use, since the reverse rotation of the first output terminal 4 and the second output terminal 5 is in a certain ratio, the internal and external shaft speed ratio of the dual-drive reducer 3 is adjusted to achieve a balanced state of the device during operation, thereby realizing the self-balancing function of the device.

[0027] Example 2

[0028] like Figure 2 As shown, this embodiment provides a dual-drive device with a self-balancing function. Since the dual-drive device motor 1 and the dual-drive reducer 3 in Embodiment 1 are horizontally arranged, there are certain deflection problems during actual use, and the use effect is not ideal. Therefore, on the basis of Embodiment 1, Embodiment 2 is improved as follows: the motor 1 is arranged above the reducer 2, and the housing of the motor 1 is connected to the housing of the dual-drive reducer 3 as a whole.

[0029] The dual-drive device described in the above embodiments 1-2 can directly adopt the dual-drive reduction mechanism (also called dual-power reduction mechanism in the early days) that is already commonly used in the washing machine industry. For example, the dual-drive (or dual-power) reduction output mechanism disclosed in patents such as CN03101149.7 and CN200710110784.3 can be used in the above embodiments 1 or 2.

[0030] Replacing the driving motor in the mopping machine with the above-mentioned dual-drive device with self-balancing function can prevent the mopping machine from self-deflecting during operation, which is convenient for users and avoids unnecessary bumps and other inconveniences. Figure 3 , Figure 4 As shown, by adding a device peripheral 8 to the device, the independent operation of the device can be realized. The device peripheral 8 can be made of wool cloth, cotton cloth, non-woven fabric, wire brush, etc. according to different uses to realize the multiple uses of the device.
