Description

Technical Field

[0001] This utility model relates to the field of dehydration mechanism technology, and in particular to a drive mechanism for an electric dehydrator. Background Technology

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

[0003] In the prior art, such as the Chinese utility model patent with publication number CN221588956U entitled "A Washing Machine with an Easy-Draining, Hole-less Tub," a washing machine with an easy-draining, hole-less tub is disclosed. It includes a casing, a water tank inside the casing, a tub lid that partially encloses the top of the water tank, a rotating power assembly at the lower end of the water tank, and a hole-less spin-drying inner tub inside the water tank that is driven by the rotating power assembly to rotate around the center line of the water tank. The inner wall of the hole-less spin-drying inner tub is evenly distributed with… There are several grooves, each forming a water outlet channel. The upper end of the non-perforated spin-drying inner tub is equipped with a balance ring, and the lower end of the water tank is equipped with a drain valve to drain water to the outside of the machine casing. When the washing machine is spinning, the rotating power component drives the non-perforated spin-drying inner tub to rotate around the center line of the water tank. The water from the clothes flows upward along the grooves of the non-perforated spin-drying inner tub, is discharged along the water outlet channel to the water tank, and is discharged from the drain valve at the bottom. This ensures that the washing machine with the non-perforated spin-drying inner tub drains water more smoothly, has a good drainage and spin-drying effect, and saves energy.

[0004] Currently, whether it's a washing machine, a mop, or a simple spin dryer, their spin-drying method all uses an electric drive mechanism to drive the spin-drying basket, which rotates to achieve centrifugal spin-drying.

[0005] Of course, all of the above situations require the equipment to be connected to a power source. In certain specific environments, such as rural areas, outdoors, or even university dormitories, it is not convenient to connect these devices to a power source. When dehydration is required, it can only be achieved by manually wringing the clothes and shoes. Not only can clothes and shoes not be dehydrated well, but manual wringing can also damage the fabric. Therefore, current dehydration mechanisms have certain limitations. Utility Model Content

Through mechanical drive, it enables the dehydration of clothing and other fabrics without the need for a power supply, resulting in good dehydration effect without damaging the fabric.

[0007] To solve the above-mentioned technical problems, the present invention provides a driving mechanism for an electric dehydrator, including a driving connection seat, a rack assembly disposed on the driving connection seat, a transmission assembly disposed in cooperation with the rack assembly, and a pedal assembly connected to the input end of the rack assembly. When the pedal assembly is stepped on or released, the output assembly can maintain a unidirectional rotation under the drive of the transmission assembly.

[0008] In the above technical solution, the rack assembly includes a rack mounting base, the rack is slidably mounted on the rack mounting base, and a linkage arm is provided at one end of the rack. The pedal assembly is linked to the rack through the linkage arm.

[0009] In the above technical solution, a linkage groove is vertically provided on the linkage arm, and the pedal assembly can move within the linkage groove, thereby driving the rack to slide along the upper working surface of the rack mounting seat.

[0010] In the above technical solution, the transmission assembly includes a first transmission mechanism, a second transmission mechanism, and a planetary gear set. The first transmission mechanism includes a first lower transmission part with a shaft tooth structure and a first upper transmission part with a gear tooth structure. The second transmission mechanism includes a second transmission part with a shaft tooth structure and a mounting part capable of mounting a transmission shaft. The planetary gear set achieves transmission by cooperating with the second transmission mechanism through the transmission shaft.

[0011] In the above technical solution, at least one set of the first transmission mechanism is provided, the first lower transmission part cooperates with the rack for transmission, and the first upper transmission part cooperates with the second transmission part for transmission.

[0012] In the above technical solution, the transmission component includes a transmission cover, and the outer shell of the planetary gear set is connected to the transmission cover.

[0014] In the above technical solution, the drive connection seat outer cover is provided with an outer cover body, and the output component and the pedal component protrude from the outer cover body through the working position reserved in the outer cover body.

[0015] In the above technical solution, the output component includes an output shaft and a one-way bearing assembly that mates with the output shaft.

[0016] In the above technical solution, the pedal assembly includes an integrally formed foot pedal part, a linkage part connected to the linkage arm, and a rotating connection part connected to the pedal mounting bracket.

After connecting the dehydration assembly, it can efficiently centrifuge dehydration of the internal items without the need for a power supply, and the operating environment is not limited, thus expanding the application range of the dehydration mechanism.

[0029] See Figures 1 to 6 A drive mechanism for a power-free dehydrator includes a drive connecting seat 1. The drive connecting seat 1 is provided with a rack mounting seat reserved position 11, a pedal mounting bracket 12, a first transmission mechanism mounting position 13, and a second transmission mechanism mounting position 131. The rack mounting seat reserved position 11 is hollowed out along the length direction of the drive connecting seat 1 and is a strip-shaped structure. The pedal mounting bracket 12 is located on both sides of the hollow structure and protrudes along the working direction on the working surface of the drive connecting seat 1. The pedal mounting bracket 12 is located away from one end of the pedal mounting bracket 12 and is mounted on the rack mounting seat reserved position 11. The first transmission mechanism mounting position 13 is provided on the rack mounting seat reserved position 11. A reserved opening 130 is provided on the side wall. The second transmission mechanism mounting position 131 is located on the top working surface of the first transmission mechanism mounting position 13.

[0030] A drive assembly is provided on the drive connector 1, and a pedal assembly 4 is connected thereto. The specific structure is as follows.

[0031] The rack assembly 2 includes a rack 22 and a rack mounting base 21. The rack mounting base 21 is fixedly connected to the drive connection base 1 through the rack mounting base reserved position 11. The rack 22 is slidably mounted on the rack mounting base 21. A linkage arm 23 is provided at one end of the rack 22, i.e., the input end. A linkage groove 231 is vertically provided on the linkage arm 23. The pedal assembly 4 can move within the linkage groove 231 and drive the rack 22 to slide along the upper working surface of the rack mounting base 21.

[0032] The pedal assembly 4 includes an integrally formed foot pedal part 41, a linkage part 42, and a rotating connection part 43. The foot pedal part 41 extends away from the drive connection seat 1. The linkage part 42 is connected to the linkage arm 23 and can slide vertically in the linkage groove 231. The rotating connection part 43 is rotatably connected to the pedal mounting bracket 12. In order to provide torque, a torsion spring is provided on the connecting rod of the rotating connection part 43 to improve the customer experience.

[0033] The sliding of the rack 22 enables the transmission component 3 to move. The transmission component 3 includes a first transmission mechanism 31, a second transmission mechanism 32, and a planetary gear set 33. When the strength requirement is met, one set of the first transmission mechanism 31 is sufficient to meet the usage requirements. However, under normal circumstances, considering extreme conditions, and in order to improve the stability of the product, as a preferred solution, we provide two sets of the first transmission mechanism 31 with identical structures, arranged back and forth along the strength direction of the rack 22 and meshing with the rack 22 respectively.

[0034] The first transmission mechanism 31 is inserted into the groove of the first transmission mechanism mounting position 13, including a first lower transmission part 311 with a shaft tooth structure and a first upper transmission part 312 with a gear tooth structure. The second transmission mechanism 32 is set through the second transmission mechanism mounting position 131, including a second transmission part 321 with a shaft tooth structure and a mounting part. The first lower transmission part 311 has a reserved opening 130 on its side wall so that the first lower transmission part 311 can cooperate with the rack 22 for transmission. The first upper transmission part 312 cooperates with the second transmission part 321 for transmission.

[0035] The drive shaft 6 is connected to the second transmission mechanism 32 via the mounting part, and the planetary gear set 33 is connected to the second transmission mechanism 32 via the drive shaft 6 to achieve transmission. The planetary gear set 33 is beneficial for accelerating movement during the transmission process.

[0036] The transmission assembly 3 also includes a transmission cover 34. The first transmission mechanism 31 and the second transmission mechanism 32 are kept vertically limited by the transmission cover 34. The outer shell 331 of the planetary gear set 33 is connected to the transmission cover 34, which provides a limiting and protection function for the planetary gear set 33.

[0037] The output assembly 5 is connected to the planetary gear set 33 and includes an output shaft 51 and a one-way bearing assembly 52. ​​The one-way bearing assembly 52 can maintain the one-way rotation of the output shaft 51.

[0038] The drive connector 1 has an outer cover 7. The output component 5 and the pedal component 4 protrude from the outer cover 7 through the working position reserved in the outer cover. More specifically, the foot pedal 41 extends out of the outer cover 7 for easy foot pedaling. The extension end of the output shaft 51 extends out of the outer cover 7 and can be connected to the dehydration mechanism.

[0039] When the above technical solution is used, the principle is as follows: When 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 231 and drive the rack 22 to slide away from the pedal part 41 along the upper working surface of the rack mounting seat 21. The sliding of the rack 22 can cause the transmission component 3 that it cooperates with to move, thereby converting linear motion into rotational motion. The planetary gear set can accelerate the rotational motion, improve the rotational efficiency, and transmit the rotational force to the dehydration mechanism at the output end by the output shaft 51. Under the action of the one-way bearing assembly 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 rotational motion of the output shaft 51 is always maintained.

[0040] This mechanism can be used in mop spin-drying mechanisms, clothing spin-drying mechanisms, and other equipment requiring dehydration. Simply connect the dehydration component to the structure in this solution to form a dehydration device. It can be used in various scenarios, including when there is no power supply, such as in university dormitories and outdoors. When dehydration is needed, centrifugal dehydration is achieved through foot pedal mechanical transmission, eliminating the need for manual wringing. It not only has high dehydration efficiency but also good results, without damaging the fabric, which is conducive to market promotion and has a good market prospect.

[0041] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
