Description

Technical Field

[0001] The utility model relates to the technical field of dehydration mechanisms, in particular to a 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, there is a Chinese utility model patent with publication number CN221588956U, entitled "A washing machine with an easy-draining non-porous barrel", which discloses a washing machine with an easy-draining non-porous barrel, comprising a housing, a water barrel provided in the housing, a barrel cover which semi-closes the upper part of the water barrel installed on the top of the water barrel, a rotating power assembly provided at the lower end of the water barrel, a non-porous dehydration inner barrel 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 not be dehydrated well, but this manual wringing method will cause damage to the fabric. Therefore, the current dehydration mechanism has certain limitations. Utility Model Content

Through mechanical drive, clothing and other fabrics can be dehydrated without the need for power supply, and the dehydration effect is good without causing damage to the fabrics.

When the driving pedal is stepped down or released, the spiral transmission mechanism maintains a unidirectional rotation action, and realizes power output that can achieve rotation without power supply through the mechanical method of pedaling.

[0008] In the above technical solution, the guide sleeve includes a first cavity and a second cavity which are coaxially arranged from top to bottom and open at both ends. A symmetrical guide groove is vertically opened on the side wall of the second cavity, and a hollow limiting protrusion is coaxially arranged at the transition position between the first cavity and the second cavity.

[0009] In the above technical solution, an acceleration component that cooperates with the transmission screw component is provided in the first cavity, including a planetary gear set.

[0010] In the above technical solution, the top cover of the first cavity is provided with a fixed cover for the acceleration component, and the top of the fixed cover is provided with a transmission hole for transmission output, which can be used to connect the dehydration structure.

[0011] In the above technical solution, the transmission screw assembly includes a rotating screw and a one-way bearing group cooperating with the rotating screw. The rotating screw is arranged in the second cavity, and the lower working end of the rotating screw is inserted into the transmission seat, and the upper working end of the rotating screw cooperates with the one-way bearing group.

[0012] In the above technical solution, the transmission seat is arranged in the guide sleeve, and includes a seat body, the seat body has an upper cavity and a lower cavity that are coaxially arranged and interconnected, the lower working end of the rotating screw passes through the upper cavity and cooperates with the thread of the inner wall of the lower cavity, and the transmission arm symmetrically arranged on the outer wall of the seat body extends out from the notch of the guide groove.

[0013] In the above technical solution, a compression spring installation position is provided at the transition position between the upper cavity and the lower cavity, one end of the reset compression spring sleeved outside the rotating screw is resting on the compression spring installation position, and the other end of the reset compression spring is sleeved on the limiting protrusion inside the guide sleeve.

[0014] In the above technical solution, a pedal rotating frame is provided on the driving connecting seat.

[0015] In the above technical solution, the driving pedal includes a driving end and a mating end, and a rotating connection position is provided on the two side walls between the driving end and the mating end. The driving pedal is rotatably connected to the pedal rotating frame through the rotating connection position, so that a fulcrum is formed when stepping on it, and it rotates along the pedal rotating frame to realize mechanical power output.

[0016] In the above technical solution, the dehydration component is connected to the spiral transmission mechanism through the transmission hole, and is then driven to achieve dehydration.

[0017] Compared with the prior art, the present invention has the following beneficial effects: the rotation of the spiral transmission mechanism is realized by adopting a mechanical drive method of a driving pedal, and the setting of a one-way bearing group can ensure that the spiral transmission mechanism maintains a one-way rotation movement. When the dehydration component is connected, centrifugal dehydration of the items in the dehydration component can be achieved without connecting to a power supply. The use environment is not limited, which expands the scope of use of the dehydration mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Specifically, the guide sleeve 2 includes a first cavity 21 and a second cavity 22 arranged coaxially. The top of the first cavity 21 is open, and the bottom of the second cavity 22 is open. The bottom of the first cavity 21 is connected to the top of the second cavity 22. A flat surface for mounting other structures is provided on the upper surface of the transition connecting the two cavities. In other words, the inner diameter of the second cavity 22 is smaller than that of the first cavity 21. A limiting protrusion 222 is provided on the lower surface of the transition connecting the first cavity 21 and the second cavity, extending into the second cavity 22 and coaxially with the first cavity 21 and the second cavity 22. The limiting protrusion 222 is arranged circumferentially around the top opening of the second cavity 22 and is a hollow structure. A symmetrical guide groove 221 is vertically provided on the side wall of the second cavity 22.

[0032] The screw transmission mechanism 3 includes a transmission base 31 and a transmission screw assembly 32 .

[0033] The transmission seat 31 includes a seat body, which has an upper cavity 312 and a lower cavity 313 set coaxially. The top of the upper cavity 312 is open, and the bottom of the lower cavity 313 is open. A threaded structure is provided on the inner wall. The tops of the upper cavity 312 and the lower cavity 313 are connected, and the upper surface of the transition connecting the two cavities is provided with a plane for installing other structures. That is to say, the inner diameter of the lower cavity 313 is smaller than the inner diameter of the upper cavity 312, and a compression spring mounting position 314 set coaxially with the first cavity 21 and the second cavity 22 is provided on the upper surface of the transition connecting the upper cavity 312 and the lower cavity 313, extending into the upper cavity 312, and a transmission arm 311 is symmetrically provided on the outer side wall of the lower cavity 313.

[0034] The transmission screw assembly 32 includes a rotating screw 321 and a one-way bearing assembly 322 .

[0035] The transmission seat 31 is installed at the bottom of the guide sleeve 2, and a thrust bearing 30 is provided at the contact position between the lower working end of the transmission seat 31 and the drive connecting seat 1. The transmission arm 311 extends from the notch of the guide groove 221, and the threaded inner wall of the lower cavity 313 of the lower working end of the rotating screw 321 is transmitted. The return compression spring 33 is sleeved on the outside of the rotating screw 321, and one end of the return compression spring 33 is abutted on the compression spring mounting position 314, and the other end of the return compression spring 33 is sleeved on the limiting protrusion 222 in the guide sleeve 2. The upper working end of the rotating screw 321 extends into the second cavity 22 of the guide sleeve 2 after passing through the upper cavity 312, and cooperates with the one-way bearing group 322 set at the upper working end of the guide sleeve 2.

[0036] In order to accelerate the rotational movement during pedaling, an acceleration component 5 is provided in the first cavity 21 of the guide sleeve 2 to cooperate with the one-way bearing group 322. A planetary gear set is preferably used. Of course, it is not limited to a planetary gear set, and any structure that can meet the acceleration requirements can be used.

[0037] In order to ensure the stability of the operation of the planetary gear set, a fixed cover 6 for the acceleration component 5 is provided on the top cover of the first cavity 21. A transmission hole 61 that enables transmission output is provided on the top of the fixed cover 6. The dehydration component 7 can be connected to the spiral transmission mechanism 3 through the transmission hole 61.

[0038] As a structure for mechanical force output, the driving pedal 4 includes a driving end 41 and a mating end 42. A rotating connection position 43 is provided on the two side walls between the driving end 41 and the mating end 42. The driving pedal 4 is rotatably connected to the pedal rotating frame 11 through the rotating connection position 43. The mating end 42 is provided with a connecting arm 421, which corresponds to the number of the transmission arm 311 and is used for power input to the spiral transmission mechanism 3. The driving end 41 is provided with a pedal surface 411 for stepping on.

[0039] When the above technical solution is in use, the principle is as follows: when the user steps on the footrest surface 411, the mating end 42 of the driving pedal 4 will drive the transmission seat 31 to move upward along the guide groove 221, and the rotating screw 321 that cooperates with the thread on the inner wall of the lower cavity 313 rotates under the action of the transmission seat 31, thereby realizing rotation. The planetary gear set can accelerate the rotation and improve the rotation efficiency. In the process of the transmission seat 31 moving upward along the guide groove 221, the spiral transmission mechanism 3 maintains a unidirectional rotation action, and the reset spring 33 is in a compressed state at this time; the force applied to the driving pedal 4 is released, and the transmission seat 31 returns to the initial position under the action of the reset spring 33. Under the action of the one-way bearing group 322, it is ensured that the rotating screw 321 will not reverse. In this way, when the user repeatedly steps on the footrest surface 411, the rotating screw 321 always maintains a unidirectional rotation action.

[0040] The 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 with the spiral transmission 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 the effect is also good, and it will not cause damage to the fabric, which is conducive to market promotion and has good market prospects.

The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
