Description

Technical Field

[0001] This invention relates to the field of clothing dehydration technology, specifically to a double-speed transmission planetary gear system clothing dehydration device. Background Technology

[0002] After washing, clothes need to be dehydrated to shorten drying time and reduce problems such as odor and mold growth caused by residual moisture. However, in situations with power restrictions (such as student dormitories), existing high-power appliances such as washing machines and spin dryers are strictly prohibited from use due to exceeding power limits, and clothes can only be dehydrated manually.

[0003] Currently available manual dehydration equipment, such as manual dehydration drums and other simple dehydration devices, can replace electrical appliances to a certain extent for dehydrating clothes, but they still have at least the following drawbacks in practical applications: (1) Poor dehydration effect, making it difficult to meet the drying needs. For example, if the device that drives the inner drum to rotate to generate centrifugal force to achieve dehydration has an unreasonable transmission structure design, the inner drum speed is difficult to increase, the centrifugal force is insufficient, resulting in more residual moisture in the clothes; (2) The operation is laborious and the user experience is poor. Users need to continuously crank the inner drum to rotate, which results in low utilization of human kinetic energy. In addition, a large amount of cranking force is required to maintain the rotation speed during the dehydration process. A single dehydration operation often requires a lot of physical strength, making the operation difficult and tiring. (3) The structural design is unreasonable and the safety and applicability are insufficient. The support structure of some manual spin dryers is weak, and they are prone to shaking and tipping during high-speed spin drying, which poses a safety hazard of clothes being thrown out and users being bumped. On the other hand, the pull rope spin dryer is easily worn and cannot meet the needs of long-term use.

[0004] In summary, the demand for clothing dehydration has not been effectively met under power rationing conditions. Existing dehydration equipment suffers from poor dehydration effect, laborious operation, and insufficient safety and applicability, which seriously affects users' daily life experience. Therefore, there is an urgent need to develop a manual clothing dehydration device that can adapt to power rationing scenarios, has a good dehydration effect, is labor-saving to operate, and is highly safe. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a double-speed transmission planetary gear system clothes dehydration device. The planetary gear system transmits the driving force of the drive mechanism to the drum, which saves effort during operation, can significantly improve the transmission ratio, and thus improve the dehydration effect to meet the needs of clothes drying.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a double-speed transmission planetary gear system garment dehydration device, comprising a base, a housing mounted on the base, a roller disposed on the inner side of the housing, the roller having multiple dehydration holes, a planetary gear system transmission mechanism and a drive mechanism disposed on the outer side of the housing, the drive mechanism being connected to the roller through the planetary gear system transmission mechanism, and the drive mechanism being able to drive the roller to rotate relative to the housing around its own axis through the planetary gear system transmission mechanism; The planetary gear transmission mechanism includes a driving gear and a fixed frame gear arranged coaxially. The driving gear is connected to the output end of the drive mechanism. A transmission shaft is mounted on the fixed frame gear. One end of the transmission shaft is connected to the roller, and the other end of the transmission shaft is connected to a planet carrier for driving the transmission shaft to rotate. The planet carrier is located between the driving gear and the fixed frame gear. The driving gear has multiple primary planetary gears meshing around its circumference, and the fixed frame gear has secondary planetary gears meshing around its circumference, corresponding to the number and position of the primary planetary gears. The planet carrier is provided with planetary shafts for connecting the primary planetary gears and the secondary planetary gears.

[0007] Optionally, the planetary gear train transmission mechanism further includes a cage connected to the fixed frame gear, the planetary shaft being parallel to the transmission shaft, and the cage being connected to the housing.

[0008] Optionally, the planetary gear train transmission mechanism is provided in two sets, one of which is connected to the drive mechanism, and the other is connected to the roller, and the two sets of planetary gear train transmission mechanisms are connected to each other through a transmission shaft close to the drive mechanism.

[0009] Optionally, the drive mechanism includes an inertial flywheel that can move synchronously with the adjacent drive gear. A handle for driving the inertial flywheel to rotate is provided on the side of the inertial flywheel opposite to the planetary gear transmission mechanism. The handle is connected to the inertial flywheel via a one-way component.

[0010] Optionally, the one-way component includes a ratchet groove and a ratchet disc rotatably mounted in the ratchet groove. The ratchet groove is formed on the inertial flywheel, and the ratchet disc is fixedly connected to the grip. The inner circumferential surface of the ratchet groove is provided with ratchet teeth, and the outer circumferential surface of the ratchet disc is provided with pawls that cooperate with the ratchet teeth.

[0011] Optionally, a first cover plate is provided on the side of the base near the inertial flywheel, and a drive shaft is passed through the first cover plate. One end of the drive shaft is fixedly connected to the inertial flywheel, and the other end of the drive shaft is connected to the drive gear.

[0012] Optionally, a support cylinder is fixedly installed between the first cover plate and the outer shell, the planetary gear transmission mechanism is located inside the support cylinder, and the cage is fixedly connected to the support cylinder.

[0013] Optionally, a second cover plate is provided on the side of the base opposite to the first cover plate. The second cover plate and the inner wall of the outer shell form a closed dehydration chamber. The roller is rotatably installed in the dehydration chamber, and a door panel for opening and closing the dehydration chamber is provided on the second cover plate.

[0014] Optionally, the outer shell has a drain hole at one end near the first cover plate that communicates with the dehydration chamber. A push-pull rod is slidably passed through the first cover plate. A plug that can be embedded in the drain hole is connected to one end of the push-pull rod near the outer shell. The plug is used to block or open the drain hole.

[0015] Optionally, a water storage tank is provided on the base, the water storage tank is located below the planetary gear transmission mechanism and communicates with the drain hole, and the base is also provided with a drain outlet communicating with the water storage tank.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In this invention, the drive mechanism drives the active gear to rotate, so that the main planetary gear revolves around the active gear and rotates around its own axis at the same time, and forms a planetary gear in the planetary gear system with the secondary planetary gear, which drives the planet carrier to rotate, and then the planet carrier drives the transmission shaft to rotate, thereby driving the drum to rotate and generating centrifugal force, so as to achieve the purpose of dehydrating the clothes in the drum; the device uses a planetary gear system to transmit the driving force of the drive mechanism to the drum, which saves effort in the operation process, can significantly improve the transmission ratio, and thus improve the dehydration effect and meet the needs of drying clothes; (2) In this invention, after the inertial flywheel of the drive mechanism is driven to rotate by the handle, the overall rotation speed of the drum can be kept relatively stable, reducing the influence of the hand-cranked rotation speed on the drum rotation speed, ensuring the stability of the drum rotation and the safety and applicability of the device, and improving the user experience. (3) In this invention, the support sleeve is installed on the outside of the planetary gear transmission mechanism, which can provide support for it, prevent its precision transmission structure from being affected by the external environment, extend the service life of the equipment, and prevent the planetary gear system from causing harm to the user during operation, thereby improving the safety performance of the equipment. (4) In this invention, a water storage tank is provided on the base, which can not only ensure that the water removed from the clothes can be discharged from the dehydration chamber to ensure the dehydration effect, but also play the role of dehydration storage, preventing water accumulation on the ground, so that the water removed from the clothes can be temporarily stored in the water storage tank, enabling the equipment to operate in different locations and improving its environmental compatibility and applicability. (5) In this invention, the two-stage transmission consisting of two planetary gear transmission mechanisms can further convert the low-speed drive of the hand crank into the high-speed rotation of the drum, making the dehydration effect of the equipment better and the dehydration efficiency higher. (6) In this invention, the device adopts a modular and compact design, making it small in size and lightweight. It can be flexibly placed in dormitories, storage shelves or room corners without occupying drying and activity space. It is suitable for small living environments such as dormitories and solves the drawback of traditional laundry equipment occupying a lot of space. Moreover, there is no need to use a pull rope. Compared with pull rope manual equipment, there is no need to frequently replace parts, reducing the difficulty of equipment maintenance. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention and therefore only show the components relevant to the present invention.

[0019] Example 1, as Figures 1-5 As shown, a high-speed planetary gear system garment dehydration device includes a base 1, a housing 2, a roller 3, a planetary gear system transmission mechanism 4, and a drive mechanism. The housing 2 is fixedly installed on the base 1, and the roller 3 is rotatably installed inside the housing 2. The planetary gear system transmission mechanism 4 and the drive mechanism are located on the outside of the housing 2. The drive mechanism is connected to the roller 3 through the planetary gear system transmission mechanism 4, so that the drive mechanism can drive the roller 3 to rotate relative to the housing 2 around its own axis through the planetary gear system transmission mechanism 4. A plurality of dehydration holes 301 are opened on the outer circumferential surface of the roller 3.

[0020] The drive mechanism drives the drum 3 to rotate relative to the outer shell 2 around its own axis. The planetary gear transmission mechanism 4 transmits the driving force of the drive mechanism to the drum 3 to increase the transmission ratio between the drive mechanism and the drum 3. The clothes to be dehydrated are placed inside the drum 3. When the drum 3 rotates relative to the outer shell 2 around its own axis, centrifugal force is generated. The centrifugal force causes the water adsorbed on the clothes to be removed from the clothes and pass through the dehydration hole 301, thereby achieving the purpose of dehydrating the clothes inside the drum 3 and enabling the equipment to meet the needs of clothes drying.

[0021] The double-speed transmission planetary gear system garment dehydration device of the present invention uses a planetary gear system transmission mechanism 4 with a large transmission ratio to transmit the low speed drive of the drive mechanism to the drum 3, thereby improving the dehydration efficiency and effect by increasing the speed of the drum.

[0022] As described above, a first cover plate 101 is fixedly installed at one end of the base 1, and a second cover plate 102 is fixedly installed at the other end of the base 1. The first cover plate 101 and the second cover plate 102 are distributed relatively parallel to each other. The outer shell 2 is fixedly installed on the base 1 in a cylindrical structure, and the open end of the outer shell 2 is fitted with the second cover plate 102, so that the second cover plate 102 and the inner wall of the outer shell 2 enclose a sealed dehydration chamber 201. The roller 3 is rotatably installed in the dehydration chamber 201 and is coaxial with it. The drive mechanism is installed on the first cover plate 101, and the planetary gear transmission mechanism 4 is located between the closed end of the outer shell 2 and the first cover plate 101.

[0023] The roller 3 has a rotating shaft fixedly installed at both ends. One end of the rotating shaft passes through the closed end of the outer shell 2 and is connected to the planetary gear transmission mechanism 4. The other end of the rotating shaft passes through the second cover plate 102. Bearings are provided between the rotating shaft and the second cover plate 102 and the closed end of the outer shell 2.

[0024] Furthermore, the roller 3 is provided with a plurality of pick-up and put-down holes 302 that communicate with the inner cavity of the roller 3 on the side near the second cover plate 102. The plurality of pick-up and put-down holes 302 are arranged in a circular array around the axis of rotation. Moreover, a door hole communicating with the dehydration chamber 201 is provided on the second cover plate 102 to facilitate the picking up and putting down of clothes in the roller 3. A door plate 8 for opening and closing the dehydration chamber 201 is provided in the door hole. The door plate 8 can be opened and closed relative to the second cover plate 102.

[0025] When the door panel 8 is opened, clothes can be sent into the drum 3 through the door hole and the loading and unloading hole 302, or clothes can be taken out from the drum 3; when the door panel 8 is closed, the airtightness of the dehydration chamber 201 can be ensured, and clothes can be prevented from being thrown out during the high-speed rotation of the drum 3.

[0026] To ensure the dehydration effect and allow the water removed from the clothes to be smoothly discharged from the dehydration chamber 201, a drain hole 103 communicating with the dehydration chamber 201 is provided at one end of the outer shell 2 near the first cover plate 101 (i.e., the closed end). The drain hole 103 is located near the bottom of the outer shell 2 so that the water in the dehydration chamber 201 can be completely discharged.

[0027] Example 2: Based on Example 1, the present invention discloses the specific structure of the driving mechanism.

[0028] like Figures 1-4 and Figure 7 As shown, the drive mechanism includes an inertia flywheel 5, a drive shaft 501, a handle 6, and a one-way assembly. The drive shaft 501 is mounted on the first cover plate 101 via a bearing. One end of the drive shaft 501, near the outer casing 2, is connected to the input end of the planetary gear transmission mechanism 4, and the other end is fixedly connected to the inertia flywheel 5. The handle 6 is located on the side of the inertia flywheel 5 opposite to the first cover plate 101, and the handle 6 is connected to the inertia flywheel 5 via the one-way assembly.

[0029] The drive shaft 501 and the inertia flywheel 5 are coaxially distributed. The handle 6 adopts a Z-shaped structure. Under the action of the unidirectional component, the handle 6 can only drive the inertia flywheel 5 to rotate in one direction, and then transmit the torque to the planetary gear transmission mechanism 4 through the drive shaft 501. The inertia flywheel 5 is made of 304 stainless steel and has the characteristics of large rotational inertia, which can keep the overall speed of the roller 3 basically stable and not be excessively affected by the hand-cranked speed.

[0030] The one-way component includes a ratchet groove 502 and a ratchet disc 7 rotatably mounted within the ratchet groove 502. The ratchet groove 502 is formed on the inertia flywheel 5. The ratchet disc 7 is fixedly connected to the handle 6. Ratchets are formed on the inner circumferential surface of the ratchet groove 502, and pawls 702 that engage with the ratches are formed on the outer circumferential surface of the ratchet disc 7. When the handle 6 drives the ratchet disc 7 to rotate forward, the pawls 702 abut against the ratches, thereby driving the inertia flywheel 5 to rotate. When the hand cranking speed is reduced, the rotational speed of the inertia flywheel 5 is greater than the rotational speed of the ratchet disc 7. At this time, the ratchet disc 7 rotates in the opposite direction relative to the inertia flywheel 5, and the ratches and pawls 702 slip relative to each other, preventing the torque of the inertia flywheel 5 from being transmitted to the handle 6 in the opposite direction through the ratchet disc 7.

[0031] Therefore, after the inertial flywheel 5 is driven to rotate by the handle 6, the overall rotation speed of the roller 3 can be kept relatively stable, reducing the influence of the hand-cranked speed on the rotation speed of the roller 3, ensuring the stability of the rotation of the roller 3, as well as the safety and applicability of the device, and improving the user experience.

[0032] The ratchet disc 7 has multiple grooves 701 on its outer circumferential surface, each groove 701 containing a movably mounted pawl 702. One end of the pawl 702 is rotatably connected to the side of the groove 701, and a spring 703 is positioned between the inner side of the pawl 702 and the bottom of the groove 701. When the ratchet disc 7 rotates forward, the end of the pawl 702 abuts against the ratchet teeth to transmit torque. When the ratchet disc 7 rotates in the opposite direction relative to the inertial flywheel 5, the ratchet teeth apply pressure to the pawl 702 from the outside, causing the pawl 702 to overcome the elastic force of the spring 703 and embed itself into the groove 701. After the pressure from the ratchet teeth disappears, under the action of the spring 703, the end of the pawl extends again to the outside of the groove 701 to abut against the ratchet teeth. Furthermore, a handle 6 is rotatably mounted on the side opposite to the ratchet disc 7, making operation more convenient for the user.

[0033] In Example 3, based on Example 2, the present invention also proposes a specific structure for the planetary gear transmission mechanism 4, and a support cylinder 202 is fixedly installed between the first cover plate 101 and the outer shell 2, with the planetary gear transmission mechanism 4 located inside the support cylinder 202.

[0034] like Figure 1 , Figure 4 and Figure 6As shown, the planetary gear transmission mechanism 4 includes a driving gear 401, a fixed frame gear 402, a primary planetary gear 403, a secondary planetary gear 404, a cage 405, a drive shaft 406, a planetary shaft 407, and a planet carrier 408. The fixed frame gear 402 is fixedly connected to the inner wall of the support cylinder 202 via the cage 405. The drive shaft 406 passes through the fixed frame gear 402 within the cage 405 via bearings (the boss of the fixed frame gear 402 is interference-fitted with the center hole of the cage 405, and the drive shaft 406 passes through the center hole of the fixed frame gear 402). The second-stage driving gear 401 and the planet carrier 408 are both sleeved on the drive shaft 406 and can be fixedly connected to the fixed frame gear 402 via bearings. The frame gear 402 rotates freely. The planet carrier 408 is rotatably connected to the drive shaft 406. The driving gear 401 is fixedly connected to the drive shaft 501 of the drive mechanism. There are multiple equal numbers of main planetary gears 403, secondary planetary gears 404, and planetary shafts 407. Multiple main planetary gears 403 mesh with the circumference of the driving gear 401, and multiple secondary planetary gears 404 mesh with the circumference of the fixed frame gear 402. The coaxial main planetary gears 403 and secondary planetary gears 404 are fixedly connected by planetary shafts 407. The planetary shafts 407 are parallel to the drive shaft 406, and the planetary shafts 407 pass through the planet carrier 408 through bearings at a position away from the center of the fixed frame gear 402.

[0035] As described above, the driving gear 401 and the fixed frame gear 402 are distributed opposite to each other. The drive shaft 501 is fixedly connected to the driving gear 401, and the two can rotate synchronously. The planetary carrier 408 and the transmission shaft 406 rotate synchronously. The transmission shaft 406 can rotate relative to the planetary carrier 408 and the cage 405. The number and position of the main planetary gears 403 correspond to the number and position of the secondary planetary gears 404. When the planetary gear transmission mechanism 4 has only one set, the driving gear 401 is the input end of the transmission mechanism, and the transmission shaft 406 is its output end. That is, the transmission shaft 406 is fixedly connected to the rotating shaft of the roller 3.

[0036] Based on this, supported by the cage 405 and the planetary carrier 408, the drive shaft 501 drives the drive gear 401 to rotate. The drive gear 401 drives the main planetary gear 403 to rotate on its own axis and also revolve around the drive gear 401. The main planetary gear 403 drives the secondary planetary gear 404 to move synchronously through the planetary shaft 407. The secondary planetary gear 404 can also revolve relative to the fixed frame gear 402 while rotating on its own axis. The main planetary gear 403 and the secondary planetary gear 404 drive the cage 408 to rotate through the planetary shaft 407. The cage then drives the transmission shaft 406 to rotate. The transmission shaft 406 then drives the next stage drive gear 401 to rotate, and finally drives the drum 3 to rotate. That is, the planetary carrier 408 converts the revolution speed of the planetary gear train into the rotation speed of the drum 3, so that it can rotate stably around its own axis.

[0037] Among them, the driving gear 401, the fixed frame gear 402, the cage 405, the drive shaft 406, the planet carrier 408, the roller 3, the outer shell 2, and the inertial flywheel 5 are all coaxially arranged. The main planetary gear 403, the secondary planetary gear 404, and the planetary shaft 407 are coaxially arranged, and the number of teeth of the secondary planetary gear 404 is greater than that of the main planetary gear 403, so that the roller 3 is located on the central axis of the planetary gear transmission mechanism 4.

[0038] In Example 4, based on Example 3, the present invention can fully utilize the advantages of the large transmission ratio of the planetary gear train. Under the same size constraints, the transmission ratio of the planetary gear train transmission mechanism 4 can be larger. Theoretically, the planetary gear train transmission mechanism can be simply superimposed infinitely to obtain the required larger transmission ratio. It has strong plasticity. It is only necessary to connect the output end of the previous stage and the input end of the next stage. Therefore, the present invention also proposes a structure in which two sets of planetary gear train transmission mechanisms 4 constitute the transmission system of the double speed transmission planetary gear train clothes dehydration device.

[0039] like Figure 1 , Figure 4 and Figure 6 As shown, when there are two sets of planetary gear transmission mechanisms 4, the planetary gear transmission mechanism 4 closer to the drive mechanism is the primary transmission structure, and the planetary gear transmission mechanism 4 closer to the outer shell 2 is the secondary transmission structure. The primary transmission structure is connected to the drive mechanism, and the secondary transmission structure is connected to the roller 3. The two sets of planetary gear transmission mechanisms 4 are connected by a transmission shaft 406 closer to the drive mechanism.

[0040] Specifically, the drive gear 401 of the primary transmission structure is fixedly connected to the drive shaft 501 of the drive mechanism, and the transmission shaft 406 of the primary transmission structure is connected to the drive gear 401 of the secondary transmission structure so as to output the torque in the primary transmission mechanism to the secondary transmission structure. The transmission shaft 406 of the secondary transmission structure is connected to the rotating shaft of the roller 3 so as to transmit the torque after the two-stage transmission to the roller 3.

[0041] Example 5 illustrates the transmission ratio of planetary gear transmission mechanism 4 based on Example 4.

[0042] Assuming the planetary gear train transmission mechanism 4 is subjected to an external reverse angular velocity: when the planet carrier 408 is stationary, the equivalent rotational speed of the driving gear 401 and the fixed frame gear 402 is N. 1h / N 2h The applied reverse angular velocity is N. h The number of teeth of the driving gear 401 is Z1=30; the number of teeth of the fixed frame gear 402 is Z2=25; the number of teeth of the main planetary gear 403 is Z3=25; the number of teeth of the secondary planetary gear 404 is Z4=30; the rotational speed of the driving gear 401 is N1; the rotational speed of the fixed frame gear 402 is N2.

[0043] Based on this, the transmission ratio between the driving gear 401 and the fixed frame gear 402 in the same group i 12 It can be calculated using the following formula: i 12 =N 1h / N 2h =(N1-N h ) / (N2-N h ) = (Z3 × Z2) / (Z1 × Z4); where it is obvious that N2 = 0, substituting the specific values, we can get (N1 - N h ) / (0-N h ) = 0.69444, -(N1 / N h ) = 0.69444 - 1, N1 / N h =0.30555, so N can be obtained. h / N1=3.2727.

[0044] Therefore, the single planetary gear transmission mechanism 4 can increase the speed by 3.2727 times, while the rotational speed of the inertial flywheel 5 is amplified by the two-stage transmission structure and transmitted to the roller 3, which can achieve a speed increase of nearly 10 times.

[0045] Example 6, as Figure 1 , Figure 3 and Figure 8 As shown, one end of the door panel 8 is rotatably connected to the second cover plate 102 via a hinge, and the other end is fixedly connected to the second cover plate 102 via a pin 805 structure, ensuring that the door panel 8 will not be accidentally opened during equipment operation.

[0046] A handle 801 is fixedly installed on the outer side of the door panel 8. The bolt 805 structure includes a locking block 802, a bolt 805, and a pin 806. The locking block 802 is fixedly installed on the second cover plate 102 at the position corresponding to the handle 801. A lock hole 803 is opened inside the locking block 802. A sliding groove 804 communicating with the lock hole 803 is opened on the outer side of the locking block 802. The pin 806 is vertically fixedly installed on the outer side of the bolt 805. The bolt 805 slides through the lock hole 803, and the pin 806 can slide along the sliding groove 804.

[0047] Specifically, the sliding groove 804 adopts an inverted U-shaped structure, including a horizontal section and two vertical sections. When the pin 806 is in the horizontal section, it can drive the pin 805 to move along the axis of the insertion hole until it is inserted into or disengaged from the inner hole of the handle 801. When the pin 806 is embedded in the vertical section on the right, the pin 805 cannot move axially. At this time, the pin 805 disengages from the inner hole of the handle 801, and the door panel 8 can be opened and closed freely. When the pin 806 is embedded in the vertical section on the left, the pin 805 also cannot move axially. At this time, the end of the pin 805 is embedded in the inner hole of the handle 801, which can ensure that the door panel 8 will not be accidentally opened during the operation of the equipment and prevent clothes from being thrown out.

[0048] Example 7, as Figure 1 and Figure 9 As shown, water in the dehydration chamber 201 can be discharged from the outer shell 2 through the drain hole 103. In order to avoid water accumulation on the ground, a push-pull rod 9 is slidably provided on the first cover plate 101. A plug 901 that can be embedded in the drain hole 103 is fixedly connected to one end of the push-pull rod 9 near the outer shell 2. The plug 901 is used to block or open the drain hole 103.

[0049] Specifically, by pushing the plug 901 to one side of the outer casing 2 with the push-pull rod 9, it is aligned with and embedded in the drain hole 103, thus sealing the drain hole 103. After the clothes are dehydrated, the plug 901 is pulled to the other side with the push-pull rod 9 to remove it from the drain hole 103, allowing the water in the dehydration chamber 201 to be discharged from the outer casing 2 through the drain hole 103. In other words, the device can drain water after the clothes are dehydrated, or it can drain water while the device is running, ensuring that there is no possibility of water in the outer casing flowing back into the drum, and ensuring that the dehydration function of the device can be realized smoothly.

[0050] Furthermore, two baffles 903 are fixedly installed on the outer side of the first cover plate 101. The two baffles 903 are distributed opposite each other on the upper and lower sides of the push-pull rod 9, and the two baffles 903 have notches on the side of the push-pull rod 9 that fit with the first cover plate 101. Two oppositely distributed insert plates 902 are fixedly installed on the push-pull rod 9. The insert plates 902 are perpendicular to the axis of the push-pull rod 9. When the plug 901 is inserted into the drain hole 103, the insert plate 902 fits with the first cover plate 101 and can be inserted into the notch to lock the axial movement of the push-pull rod 9, preventing the plug 901 from accidentally falling off. Conversely, when the insert plate 902 is disengaged from the notch, the push-pull rod 9 can move axially to ensure orderly drainage of the dehydration chamber 201.

[0051] To prevent the water discharged from the dehydration chamber 201 from affecting the ground environment, a water storage tank 104 is provided on the base 1. The water storage tank 104 is located below the planetary gear transmission mechanism 4 and between the closed end of the outer shell 2 and the first cover plate 101. The base 1 is also provided with a drain outlet 105. The water storage tank 104 is connected to the dehydration chamber 201 through the drain hole 103, and the drain outlet 105 is connected to the water storage tank 104. Based on this, the water separated from the clothes in the dehydration chamber 201 can flow into the water storage tank 104 through the drain hole 103 and can be discharged from the water storage tank 104 to a designated location through the drain outlet 105.

[0052] During the operation of the equipment, the drain outlet 105 can be closed first, so that the water is stored in the water storage tank 104. After all the clothes have been spun out or the water level in the water storage tank 104 has exceeded the drain hole 103, the equipment can be moved to the drainage position, the drain outlet 105 can be opened, and the water in the water storage tank 104 can be drained out.

[0053] In addition, to ensure the airtightness of the device, rubber sealing rings are provided at the connection between the outer shell 2 and the second cover plate 102 and between the base 1 and the first cover plate 101. The former is used to ensure the airtightness of the dehydration chamber 201, and the latter is used to ensure that the water storage tank 104 does not leak.

[0054] Example 8: Based on the above examples, the present invention also proposes a method for using a double-speed transmission planetary gear system garment dehydration device, including feeding in the garments to be dehydrated, rotating the drum 3, collecting the dehydrated garments, and draining the water.

[0055] Loading clothes to be dehydrated: First, open the door panel 8 and load the clothes to be dehydrated into the inner cavity of the roller 3 through the door hole and the loading / unloading hole 302. Then close the door panel 8 and lock the door panel 8 and the second cover plate 102 through the latch 805 structure.

[0056] Rotating drum 3: After the clothes have been loaded for dehydration, rotate handle 6. The handle 6 drives the inertial flywheel 5 to rotate. The torque of the inertial flywheel 5 is transmitted to the planetary gear transmission mechanism 4 through the drive shaft 501. The planetary gear transmission mechanism 4 then drives the drum 3 to rotate around its own axis. After the drum 3 rotates, under the action of centrifugal force, the water absorbed by the clothes is discharged into the dehydration chamber 201 through the dehydration hole 301.

[0057] Collect the dehydrated clothes: After the clothes have finished dehydrating, open the door panel 8 again, and take the dehydrated clothes out of the inner cavity of the drum 3 through the door hole and the pick-up and drop-off hole 302, and then close the door panel 8.

[0058] Drainage: After the clothes are removed, pull the push-pull rod 9 to open the plug 901 from the drain hole 103. The water in the dehydration chamber 201 can be discharged into the water storage tank 104 through the drain hole 103 and then discharged from the equipment through the drain hole.

[0059] In summary, this invention proposes a high-speed planetary gear system for dehydrating clothes. It features a modular and compact design, making it small and lightweight, allowing for flexible placement in dormitories, storage shelves, or corners without occupying drying or activity space. This design is suitable for the limited living space of dormitories and avoids the space-consuming drawbacks of traditional laundry equipment. The absence of a pull cord eliminates the need for frequent parts replacements after wear and tear, as is common with other manual equipment. The optimized gear transmission structure increases the speed ratio, resulting in significantly higher dehydration efficiency than manual wringing, far exceeding simple hand-cranked devices. A single dehydration cycle can be completed in 1-2 minutes, meeting the high-frequency processing needs of small items of clothing. Furthermore, the device is purely manually driven, requiring no electricity, and operates with zero energy consumption, complying with dormitory power rationing regulations. It also eliminates reliance on public facilities, saving queuing time and usage fees, thus reducing students' living costs. The device is easy to maintain, has a long service life, and is suitable for various small items of clothing such as underwear, socks, and thin garments, making it widely applicable.
