An electric mop and a cleaning bucket that do not require manual mopping cloth cleaning

Abstract

The present application provides an electric mop and a cleaning bucket that do not require manual mopping cloth cleaning. This mop uses the left and right switching meshing of the second swing gear set to achieve high-speed and low-speed rotation of the turntable. Its advantages are that the output torque and voltage of the drive motor are relatively stable. When rotating at a low speed, it ensures a large torque, which is suitable for mopping the floor and cleaning the mopping cloth. When rotating at a high speed, it is suitable for drying the water on the mopping cloth. The degree of drying can be controlled by the rotation speed. Mopping the floor with a dried mopping cloth makes the ground dry more easily. When the electric mop needs to clean the mopping cloth, put the mop head into the cleaning bucket and press it down to the bottom. The turntable rotates at a low speed, and the mopping cloth rubs against the brush to achieve the effect of cleaning the mopping cloth. When the cleaning of the mopping cloth is completed, the mop head moves upward under the action of the first spring, and the position of the mopping cloth is higher than the water level line. Press the dehydration button switch at the handle end, the turntable rotates in reverse and at a high speed, and the water on the mop is dried by centrifugal force, so that the dehydration of the mopping cloth can be realized, eliminating the trouble of manual disassembly and hand washing of the mopping cloth.

Detailed implementation manners

[0038] Please refer to Figures 1-16As shown in the figure, the present invention relates to an electric mop and a cleaning bucket that do not require manual mopping cloth cleaning, including an electric mop and a cleaning bucket 40. The electric mop includes a handle 110, a mop rod 120, and a mop head 130. The upper end of the mop rod 120 is fixedly connected to the handle 110, and the lower end of the mop rod 120 is movably connected to the mop head 130. The mop head 130 is provided with a main control board, a drive motor 10 electrically connected to the main control board, a power supply electrically connected to the main control board, and two transmission box structures. A key 111 electrically connected to the main control board is provided on the handle 110. Output worms 101 are provided at both ends of the drive motor 10. Each transmission box structure includes a first transmission gear set, a second swing gear set, an acceleration gear set, an output gear shaft 14, a return spring 11 connected to the second swing gear set, and a pushing device located on one side of the second swing gear set and electrically connected to the main control board. The output worm 101 meshes with the first transmission gear set, the first transmission gear set meshes with the second swing gear set, the second swing gear set meshes with the acceleration gear set under the action of the return spring 11, and the acceleration gear set meshes with the output gear shaft 14. The pushing device pushes the second swing gear set away from the acceleration gear set and makes the second swing gear set mesh with the output gear shaft 14. Each output gear shaft 14 extends outside the mop head 130 and is fixedly connected to a turntable 19. A mopping cloth 21 connection structure is also fixedly connected to the bottom surface of the turntable 19. A mopping cloth 21 is detachably connected to the outer surface of the mopping cloth 21 connection structure.

[0039] The cleaning bucket 40 includes a bucket body 41, a positioning component provided in the bucket body 41, and two brushes 42 provided in the bucket body 41. The two brushes 42 are provided at the bottom of the bucket body 41 and are respectively aligned with the two mopping cloths 21. The positioning component includes a fixed seat 431 with an opening at one end and a hollow structure, a top column 433 built in the fixed seat 431, and a first spring 432 built in the fixed seat 431. The fixed seat 431 is fixed to the bottom of the bucket body 41 and its opening faces the bucket mouth of the bucket body 41. One end of the first spring 432 is connected to the bottom of the bucket body 41, and the other end of the first spring 432 abuts against the bottom end of the top column 433 and pushes the top column 433 out of the opening. The bottom wall of the mop head presses against the top end of the top column 433 and makes the top column 433 move in the direction close to the bottom of the bucket body 41, so that the mopping cloth 21 contacts the brush 42.

[0040] Please refer to Figures 1-7As shown, the user can set a corresponding button 111 at the handle 110, and this button 111 is electrically connected to the main control board. By pressing the button 111, a corresponding electrical signal is sent to the main control board. In this specific embodiment, two buttons 111 are provided: a mopping button switch and a dehydration button switch. Among them, when the dehydration button switch is pressed, the main control board controls the driving motor 10 to start. The output worm 101 of the driving motor 10 drives the first transmission gear set, and then the first transmission gear set drives the second swing gear set. Moreover, under the default condition (when other buttons 111 are not pressed), the second swing gear set is disengaged from the output gear shaft 14 under the action of the return spring 11 and meshes with the acceleration gear set. The acceleration gear set then meshes with the output gear shaft 14 and drives the turntable 19 to rotate, that is, the rotation speed of the turntable 19 is between 500 and 1500 revolutions per minute. This overall gear set constitutes an acceleration gear, the torque of the turntable 19 becomes smaller, and the rotation speed becomes faster, which is suitable for dehydrating the mop 21. The mop 21 is installed on the turntable 19 through Velcro. By controlling the rotation speed of the driving motor 10 by the main control board, the water content of the dehydrated mop 21 can be controlled, so that the ground dries quickly when mopping the floor.

[0041] When the mopping button switch is pressed, the main control board controls the pushing device to start. The pushing device pushes the second swing gear set, and makes the second swing gear set disengage from the acceleration gear set and mesh with the output gear shaft 14. When the driving motor 10 starts, the output worms 101 at both ends of the driving motor 10 drive the first transmission gear set to drive the second swing gear set. The second swing gear set meshes with the output gear shaft 14 and drives the turntable 19 to rotate. At this time, the acceleration gear set is in a no-load idling state, and the rotation speed of the turntable 19 is between 200 and 400 revolutions per minute. This overall gear set is a reduction gear, the torque becomes larger, which is suitable for mopping the floor and cleaning the mop 21.

[0042] Through this mop, the high-speed and low-speed rotation of the turntable 19 is realized by the left-right switching meshing of the second swing gear set. Its advantage is that the output torque voltage of the driving motor 10 is always relatively stable. When rotating at a low speed, it ensures a large torque and is suitable for mopping operations. When rotating at a high speed, it is suitable for drying the water on the mop 21. The degree of drying can be controlled by the rotation speed. Mopping the floor with the dried mop 21 makes the ground easier to dry. Changing the manual mop mopping method to electric mopping has a fast mopping speed, shortens the mopping and cleaning time, reduces the labor intensity of the cleaner, and is very convenient to use. The present invention has the advantages of reasonable design, simple structure, high degree of mechanization, convenient use, fast cleaning speed, clean ground after cleaning, and low labor intensity, and can be widely promoted and used in units such as office places, hotels, restaurants, hospitals, schools, etc., and is particularly suitable for family housing use.

Align the two connecting slots 201 at the bottom of the electric mop with the positioning components in the cleaning bucket 40, and insert the positioning components into the connecting slots 201 to fix the electric mop. Then press the electric mop down to the bottom. At this time, the electric mop contacts the bristles 423 of the brush 42. (The water level in the cleaning bucket 40 needs to meet the standard height, submerging the brush 42 for suitable cleaning, about two centimeters higher than the highest point of the brush 42.) Press the mopping button switch at the end of the handle 110, and the turntable 19 rotates at a low speed. The mop cloth 21 rubs against the brush 42 to achieve the effect of cleaning the mop cloth 21; that is, the function of washing the mop cloth 21 without hands is realized. Moreover, when the cleaning of the mop cloth 21 is completed, release the downward pressure on the mop rod 120 held by hand, and it will automatically move upward. (By default, the force of the first spring 432 can lift the entire electric mop), that is, the electric mop moves upward under the action of the first spring 432, and the position of its mop cloth 21 is higher than the water level line. Press the dehydration button switch at the end of the handle 110, the turntable 19 rotates in reverse and at a high speed, and the water on the mop is dried by centrifugal force, so that the dehydration of the mop cloth can be realized.

[0056] Specifically, the mop cloth 21 is a circular mop cloth 21. Compared with the prior art, in this embodiment, when the electric mop is in use, the drive motor 10 drives the turntable 19 to rotate, the turntable 19 drives the mop cloth connection structure to rotate, and the mop cloth connection structure drives the mop cloth 21 to rotate. The movement trajectory of the high-speed rotating mop cloth 21 is a circle. It can be seen that compared with mop cloths 21 of other shapes, the circular mop cloth 21 can reduce the material cost of the mop cloth 21 while ensuring the cleaning area of the mop cloth 21 as much as possible.

[0057] Please refer to Figures 12-14 As shown, further, two of the brushes 42 are respectively arranged on both sides of the bottom of the barrel body 41. The brush 42 includes a strip-shaped connecting block 421. On both sides of the bottom surface of the strip-shaped connecting block 421, mounting columns 422 are vertically arranged. A number of bristles 423 are distributed on the surface of the strip-shaped connecting block 421 along its length direction; the barrel body 41 is provided with a mounting cylinder 411 corresponding to the mounting column 422. The brush 42 is inserted into the mounting cylinder 411 through the mounting column 422 and is connected to the barrel body 41; and the length of the strip-shaped connecting block 421 is greater than or equal to the diameter of the mop cloth 21. The brush 42 is inserted into the mounting cylinder 411 through the mounting column 422 and is detachably connected to the barrel body 41. After being used for a period of time, the user can manually remove the brush 42 to clean the hair that may be wound around the bristles 423; moreover, during the process of the mop cloth 21 rotating slowly with the turntable 19, the bristles 423 on the brush 42 and the mop cloth 21 are in contact with each other and rub slowly, which can effectively achieve the effect of cleaning the mop cloth 21. Moreover, the strip-shaped connecting block 421 does not occupy the space of the cleaning barrel. The length of the strip-shaped connecting block 421 is greater than or equal to the diameter of the mop cloth 21, which can ensure that the brush 42 can clean the entire mop cloth 21; in addition, through multiple experiments, it is proved that the bristles 423 of the same height have the best cleaning effect on the mop cloth 21 with a circular movement trajectory during slow rotation.

[0058] Please refer to Figure 11 As shown, further, a connecting cylinder body 412 for installing the positioning component is further arranged on the bottom of the barrel body 41 of the mop bucket, and a stabilizing column body 413 is arranged in the connecting cylinder body 412. The fixing seat 431 is sleeved on the connecting cylinder body 412, and one end of the first spring 432 located in the fixing seat 431 is sleeved on the stabilizing column body 413, and the other end of the first spring 432 abuts against the bottom end of the ejector post 433 and pushes the ejector post 433 out of the opening. The function of the connecting cylinder body 412 is to stabilize the entire positioning component. Because the mop bucket is in a high-speed rotating state during the dehydration process of the electric mop, it is prone to jitter. The fixing seat 431 is sleeved on the connecting cylinder body 412, and the bottom of the fixing seat 431 is also fixed to the bottom of the barrel body 41 of the mop bucket by screws to ensure firm connection; similarly, one end of the first spring 432 is sleeved on the stabilizing column body 413 to prevent the first spring 432 from moving randomly during the working process.

[0059] Please refer to Figure 13 as shown. Further, the top post 433 is a stepped cylinder, and the top post 433 includes an extension end 4331 and an inner end 4332 that are connected in sequence. The outer diameter of the extension end 4331 is smaller than the outer diameter of the inner end 4332. One end of the first spring 432 is sleeved on the stabilizing cylinder 413, and the other end of the first spring 432 is inserted into the top post 433 and abuts against the inner wall of the extension end 4331. And the extension end 4331 extends to the outside of the opening under the action of the first spring 432, and the inner end 4332 is clamped at the opening to achieve limiting. And a connecting cylinder 4333 is integrally formed at the top end of the extension end 4331, and a connecting groove 201 adapted to the connecting cylinder 4333 is provided on the bottom wall of the lower shell. The connecting groove 201 provided on the bottom wall of the lower shell can facilitate the assembly and positioning with the positioning component, and the function of the inner end 4332 is to prevent the top post 433 from being completely separated from the opening under the action of the first spring 432, so that the work is unstable.

[0060] The following lists the specific driving principles of the electric mop:

[0061] See Figure 6 , in which the dehydration button switch main control board controls the driving motor 10 to start. Assuming that the driving motor 10 rotates reversely, the output worm 101 of the driving motor 10 drives the first helical gear 8, and the first transmission gear set rotates counterclockwise. The first transmission gear set drives the second straight gear 6 to rotate clockwise, the second straight gear 6 drives the third straight gear 5 to rotate counterclockwise, the third straight gear 5 drives the first double gear 1 to rotate clockwise, the first double gear 1 drives the second double gear 2 to rotate counterclockwise, the second double gear 2 drives the fourth straight gear 4 to rotate clockwise, the fourth straight gear 4 drives the third double gear 3 to rotate counterclockwise, and the third double gear 3 drives the output gear shaft 14 to rotate clockwise. And by default (when other buttons 111 are not pressed), the second swing gear set is disengaged from the output gear shaft 14 under the action of the return spring 11 and meshes with the acceleration gear set, and the acceleration gear set then meshes with the output gear shaft 14 and drives the turntable 19 to rotate, that is, the rotation speed of the turntable 19 is between 500 and 1500 revolutions per minute. This overall gear set constitutes an acceleration gear, the torque of the turntable 19 becomes smaller, and the rotation speed becomes faster, which is suitable for dehydrating the mop 21. The mop 21 is installed on the turntable 19 through Velcro. By controlling the rotation speed of the driving motor 10 by the main control board, the dehydration water content of the mop 21 can be controlled, so that the ground can be quickly dried when mopping the floor.

[0062] See Figure 7, when the mopping button switch is pressed, the main control board controls the driving device to start. The driving device then pushes the second swing gear set, causing the second swing gear set to disengage from the acceleration gear set and engage with the output gear shaft 14. When the driving motor 10 starts, assuming the output worm 101 at both ends of the driving motor 10 rotates forward, it drives the first transmission gear set to rotate clockwise. Then, through the first transmission gear set, it drives the second straight tooth 6 to rotate counterclockwise, the third straight tooth 5 to rotate clockwise, the output gear shaft 14 to rotate counterclockwise and drive the turntable 19 to rotate. At this time, the acceleration gear set is in a no-load idle state. The rotation speed of the turntable 19 is between 200 and 400 revolutions per minute. This overall gear set is a reduction gear, with increased torque, suitable for mopping the floor and cleaning the mop.

[0063] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. For example, the reset spring in this embodiment can be replaced by a torsion spring, and all straight teeth and double gears can also be entirely replaced by helical teeth. The placement position of each gear can be changed and adjusted, and the size, module, and number of teeth of the gears can all be changed and adjusted. The driving device is not limited to the solenoid valve, and other driving devices can also be substituted, all of which can achieve the same purpose. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solution of the present invention should fall within the protection scope determined by the claims of the present invention.
