Description

Technical Field

[0001] The utility model relates to the technical field of dehydration mechanisms, in particular to a controllable driving mechanism for a dehydrator. Background Art

[0002] Dehydration mainly uses the centrifugal force of high-speed rotation to separate the water adsorbed on the clothes placed in the dehydration basket after washing.

[0003] In the prior art, for example, a Chinese utility model patent with publication number CN221588956U, entitled "A washing machine with an easy-draining non-porous barrel", discloses a washing machine with an easy-draining non-porous barrel, comprising a housing, a water barrel disposed in the housing, a barrel cover for semi-enclosing the upper portion of the water barrel mounted on the top of the water barrel, a rotating power assembly disposed at the lower end of the water barrel, a non-porous dehydration inner barrel disposed in the water barrel and driven by the rotating power assembly to rotate around the center line of the water barrel, and the inner side wall of the non-porous dehydration inner barrel is evenly distributed. There are several grooves, each of which forms a water outlet channel. A balance ring is provided at the upper end of the hole-free dehydration inner barrel, and a drain valve is provided at the lower end of the water tub to drain water to the outside of the casing. When the washing machine dehydrates, the rotating power component drives the hole-free dehydration inner barrel to rotate around the center line of the water tub. The water in the clothes flows upward along the grooves of the hole-free dehydration inner barrel, is discharged into the water tub along the water outlet channel, and is discharged from the drain valve at the bottom. This ensures that the washing machine with the hole-free dehydration inner barrel drains more smoothly, has good drainage and dehydration effects, and saves energy.

[0004] At present, whether it is a washing machine, a mop machine, or a simple dehydrator, their dehydration methods all use an electric drive mechanism to drive the dehydration basket, and realize centrifugal spin dehydration by driving the rotation of the dehydration basket.

[0005] Of course, the above situations all require the equipment to be connected to a power source. In certain specific environments, such as rural areas, outdoors, and even in college dormitories, it is not convenient to connect these devices to a power source. When dehydration is required, it can only be achieved through the original manual wringing method. Not only can the clothes and shoes and socks not be dehydrated well, but this manual wringing method will cause damage to the fabric. Therefore, the current dehydration mechanism has certain limitations. During the dehydration process, due to the increase in speed, the output shaft is prone to swinging, which not only causes greater vibration during the dehydration process, but also easily damages the output shaft. After the dehydration is completed, the clothes can only be taken out after the rotation of the drive mechanism stops naturally, which reduces the customer experience. Utility Model Content

[0034] The sliding movement of the rack 212 can drive the first transmission mechanism 22 , the second transmission mechanism 23 and the planetary gear set 24 to move.

[0035] When the strength is met, one group of the first transmission mechanism 22 can meet the use requirements, but under normal circumstances, considering the extreme conditions and in order to improve the stability of the product, as a preferred solution, our first transmission mechanism 22 is set in two groups with the same structure, which are arranged front and back along the strength direction of the rack 212 and respectively engage with the rack 212.

[0037] The transmission shaft 7 cooperates with the second transmission mechanism 23 through the mounting portion, and the planetary gear set 24 realizes transmission through the transmission shaft 6 and the second transmission mechanism 23. The planetary gear set 211 is conducive to accelerated movement during the transmission process.

[0038] A transmission cover is provided outside the first transmission mechanism 22 and the second transmission mechanism 23 , which can be used for vertical position limiting. The outer housing of the planetary gear set 24 is connected to the transmission cover, which plays a role in position limiting protection for the planetary gear set 24 .

[0039] The lower working end of the planetary gear set 24 is connected to the second transmission mechanism 23 and is located at the upper working end of the planetary gear set 24 . That is, the output end is connected to a flexible soft connection structure 3, which includes a first flexible connection block 31, a second flexible connection block 32 and a third flexible connection block 33 that are connected and matched. The upper working surface of the second flexible connection block 32 and the lower working surface of the second flexible connection block 32 are respectively provided with a first connection groove 321 and a second connection groove 322 arranged perpendicular to each other in the horizontal direction. The upper working surface of the first flexible connection block 31 is provided with a connection protrusion 311 adapted to the first connection groove 321, and the lower working surface of the first flexible connection block 31 is provided with an axial hole connection position 312 connected to the planetary gear set 24. The lower working surface of the third flexible connection block 33 is provided with a second connection protrusion 331 adapted to the second connection groove 322. The upper working surface of the third flexible connection block 33 is provided with an axial hole connection part 332 that matches the output component 5. It is protruded along the circumference of the third flexible connection block 33 for the installation of the shock-absorbing mounting bracket 61. The flexible soft connection structure can correct the relative displacement or deformation that occurs within a certain range during the rotation process.

[0040] The shock-absorbing assembly 6, which is arranged in conjunction with the flexible soft connection structure 3, includes a shock-absorbing mounting frame 61, a shock-absorbing bracket 62, and a buffer assembly 63. The shock-absorbing mounting frame 61 is mounted on the circumferential protrusion of the third flexible connection block 33. The shock-absorbing bracket 62 is connected to the flexible soft connection structure 3 via the shock-absorbing mounting frame 61. A buffer assembly 63 is arranged along the circumference of the shock-absorbing bracket 62 and is fixed by the connecting seat cover 11. The buffer assembly 63 includes a buffer spring and a connecting seat, which is connected to the connecting position on the connecting seat cover 11. The upper working surface of the shock-absorbing bracket 62 is provided with an axial hole 621 through which the output assembly 5 can pass. The axial hole 621 is coaxially arranged with the transmission assembly 2 and the output assembly 5. The shock-absorbing assembly absorbs or buffers vibrations during rotation, reducing the noise caused by rotation.

[0041] The output assembly 5 includes an output shaft 51 and a one-way bearing group 52. The input end of the output shaft 51 is connected to the shaft hole connecting portion 332. The output end of the output shaft 51 passes through the shaft hole 621 and protrudes from the upper working surface of the shock-absorbing bracket 62. The one-way bearing group 52 is set on the output shaft and located in the shaft hole, which can ensure that the output shaft 51 maintains a unidirectional rotation action.

[0042] The brake assembly 8 is mainly used to stop the rotation. Therefore, by cooperating with the flexible soft connection structure 3, the movement of the flexible soft connection structure 3 is controlled to achieve the deceleration or stop of the rotation.

[0043] The brake assembly 8 includes a brake cable mechanism 81, a cable 82, and a brake pad 83 linked to the brake cable mechanism 81 through the cable 82. A brake pad mounting position 611 and a cable guide position 612 are provided below the shock absorber mounting frame 61. The brake pad 83 is rotatably set on the shock absorber mounting frame 61 through the brake pad mounting position 611. Under the action of the brake cable mechanism 81, the cable 82 passing through the cable guide position 612 can control the brake pad 83 to adhere to or leave the outer wall of the third flexible connecting block 33, thereby realizing braking of the rotation.

[0044] When the above technical solution is in use, the principle is as follows: in the initial state, the cable 82 is in a tensioned state, the brake pad 83 located at the brake pad mounting position 611 leaves the outer wall of the third flexible connecting block 33, the user steps on the pedal part 41, the rotating connecting part 43 is rotatably connected to the pedal mounting bracket 12, the pedal assembly 4 can move in the linkage groove 213a, and drive the rack 212 to slide along the upper working surface of the rack mounting seat 211 away from the end of the pedal part 41, the sliding of the rack 212 can make the first transmission mechanism 22 matched therewith move, and then the second transmission mechanism 23 converts the linear motion into rotational motion, the planetary gear set can accelerate the rotational motion and improve the rotation efficiency, and the flexible soft connection structure is connected to the planetary gear The relative displacement or deformation between the wheel group and the output shaft 51 within a certain range during the rotation process can be corrected. At the same time, the flexible soft connection structure is connected to the shock absorbing component 6, which can absorb or buffer the vibration during the rotation process and reduce the noise caused by the rotation. The output shaft 51 transmits the rotational force to the dehydration mechanism at the output end. Under the action of the one-way bearing group 52, it is ensured that the output shaft 51 will not reverse. In this way, when the user repeatedly steps on the pedal part 41, the one-way rotation action of the output shaft 51 is always maintained. When it is necessary to stop, the cable 82 is released. At this time, the brake pad 83 located at the brake pad installation position 611 is in contact with the outer wall of the third flexible connection block 33. Through the action of friction, the rotation action is quickly decelerated and stopped.

[0045] This mechanism can be used in mop offline mechanisms, clothing dehydration mechanisms and other equipment that require dehydration. It only needs to connect the dehydration component to this mechanism to form a dehydration device. It can be used in a variety of usage scenarios, including usage scenarios when the power cannot be connected, including university dormitories, outdoor areas, etc. When dehydration is required, centrifugal dehydration is achieved through a mechanical transmission method of foot pedaling, and the manual wringing method is abandoned. Not only is the dehydration efficiency high, but it can also correct the relative displacement or deformation that occurs within a certain range during the rotation process, absorb or buffer the vibration during the rotation process, and the braking component can complete the deceleration or stop of the rotation in real time, thereby improving the dehydration efficiency. It has good market prospects.
