[0014] This invention also proposes a method for using a soft bed with an adjustable bed frame height, comprising the following steps:

[0015] S1: By rotating the second support leg and the first rotating column on one side of the support column, the first rotating column drives the second bevel gear to rotate, the second bevel gear drives the first bevel gear to rotate, and the first bevel gear drives the first screw to rotate, which in turn drives the U-shaped push plate to move upward. At the same time, as the U-shaped push plate moves upward, it pushes the bed frame body, backrest, support plate and bed board to rise synchronously, that is, adjust the overall height until it reaches the height required by the user. During the adjustment process, due to the meshing design of the first and second bevel gears, the stability and accuracy of the rotation are ensured, making the height adjustment more precise and stable. When the bed frame body is adjusted to the appropriate height, the rotation of the first rotating column is stopped. The first screw has self-locking properties and can maintain the current position without changing, avoiding the bed frame body from accidentally falling due to gravity or other external forces, thus ensuring the stability and safety of the height of the bed frame body.

[0016] S2: While adjusting the height, the screw inside the support column drives gear 1 to rotate, gear 1 drives gear 3 to rotate, gear 3 drives another gear 2 to rotate, and even if the two rotating columns 2 rotate at the same time, the two rotating columns 2 drive the two bevel gears 3 to rotate, the two bevel gears 3 drive the two bevel gears 4 to rotate, the two bevel gears 4 drive the two rotating columns 3 to rotate, causing the two rotating columns 3 to drive the two bevel gears 5 to rotate, the two bevel gears 5 to drive the two bevel gears 6 to rotate, causing the two bevel gears 6 to drive the two rotating shafts to rotate, that is, through the two transmission plates, the T-shaped fixing plate and the U-shaped fixing plate are unfolded. After the T-shaped fixing plate and the U-shaped fixing plate are unfolded, the contact area between the support column and the ground can be increased, thereby effectively improving the overall stability of the bed frame.

[0017] S3: When there is a lot of dust under the bed, activate the three hydraulic cylinders. The output ends of the three hydraulic cylinders push the two scrapers, scraper 1 and scraper 2, respectively, so that scraper 1 and scraper 2 leave the fixed groove. At this time, the spring 2 in the three fixed blocks rebounds and makes scraper 1 and scraper 2 contact the ground. Then, continue to activate the three hydraulic cylinders to push the dust under the bed out of the bed. When it comes into contact with the support column, the two triangular blocks 1 and two triangular blocks 2 squeeze the spring plates 1 and 2 respectively, thereby avoiding the support column and pushing the garbage under the bed out. When it is away from the support column, spring plates 2 and 1 rebound, so that the two triangular blocks 1 and two triangular blocks 2 return to their original positions. At this time, continue to activate the three hydraulic cylinders to sweep the garbage under the bed out. Since the front and back sides of the two triangular blocks 1 and two triangular blocks 2 are inclined, it will not affect the forward movement for cleaning or the backward movement for recycling. The front bottom of the fixed groove is inclined, so during the recycling process, the inclined side of the fixed groove can squeeze the three springs 2 in the three fixed blocks to rebound and recycle it into the fixed groove.

[0018] S4: By rotating the knob, the knob drives the screw two to rotate, the screw two drives the moving plate to move, that is, drives the moving tube to move to the left, so that the rack and pinion mesh with the gear four, and drives the gear four to rotate. The rotation of the gear four drives the rotating column to rotate, the rotating column drives the bevel gear ten to rotate, the bevel gear ten drives the bevel gear nine to rotate, the bevel gear nine drives the rotating rod two to rotate, the rotating rod two drives the two bevel gears eight to rotate, so that the two bevel gears seven drive the two rotating rods one to rotate, thus closing the sealing plate one;

[0019] S5: Then continue to rotate the knob, so that the moving plate drives the moving tube to move to the left, so that the rack and gear five mesh, that is, drive the rotating rod three to rotate, so that the rotating rod three drives one of the sprockets to rotate, and one of the sprockets drives the other sprocket to rotate through the chain, so that the screw three drives the sliding plate to move downward, so that the sealing plate two is opened. At this time, the fragrance inside the moving tube is replaced.

[0020] S6: After replacement, rotate the knob in the opposite direction to return the moving tube to its original position. Then, when someone sits or lies on the bed, the instantaneous force will push the top plate and pressure block downwards, causing the pressure block to squeeze the airbag. This allows the air inside the airbag to be transmitted through the connecting tube to the pipe located at the bottom. Even though the aroma diffuses faster, the squeezing action of the airbag makes the aroma diffuse more quickly and fully, enhancing the aroma's effect. In addition, this design cleverly utilizes the pressure generated by the body weight to achieve automatic aroma diffusion without the need for additional electricity or manual operation, making it energy-saving, environmentally friendly, convenient, and quick.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. In this solution, rotating the first rotating column manually drives the second bevel gear to rotate, which in turn drives the first bevel gear to rotate, which in turn drives the first screw to rotate, thereby moving the U-shaped push plate upward and adjusting the overall height.

[0023] 2. This solution uses a screw inside the support column to drive a gear to rotate, which in turn drives a gear to rotate, which in turn drives another gear to rotate. This allows the two rotating columns to rotate simultaneously, and through linkage, the two transmission plates can drive the T-shaped fixing plate and the U-shaped fixing plate to unfold, thereby improving the stability of the support column.

[0024] 3. This solution involves activating three hydraulic cylinders. The output ends of these cylinders push scraper blades 1 and 2 away from the fixed grooves. At this point, springs 2 within the three fixed blocks rebound, causing scraper blades 1 and 2 to contact the ground. Continuing to activate the three hydraulic cylinders pushes the dust under the bed out of the bed. When the scraper blades reach the support pillar, triangular blocks 1 and 2 squeeze spring plates 1 and 2 respectively, thus avoiding the support pillar and pushing the debris out of the bed. Once the debris is away from the support pillar, spring plates 2 and 1 rebound, returning triangular blocks 1 and 2 to their original positions. Continuing to activate the three hydraulic cylinders then sweeps the debris out of the bed.

[0025] 4. In this solution, rotating the knob drives the screw two to rotate, which in turn drives the moving plate to move, thus moving the moving tube to the left. This causes the rack and pinion to mesh with the gear four, which in turn drives the gear four to rotate. Through this linkage, the two bevel gears seven drive the two rotating rods one to rotate, thereby closing the sealing plate one.

[0026] 5. By continuously rotating the knob, the moving plate can move the moving tube to the left, causing the rack and gear five to mesh, which in turn drives the rotating rod three to rotate. The rotating rod three then drives one of the sprockets to rotate, and one of the sprockets drives the other sprocket one to rotate via a chain. This causes the screw three to move the sliding plate downward, thus opening the sealing plate two. At this point, the aromatherapy inside the moving tube can be replaced.

[0027] 6. By rotating the knob in the opposite direction, the moving tube can be returned to its original position. Then, when someone sits or lies on the bed, the instantaneous force will push the top plate and the pressure block downwards, causing the pressure block to squeeze the airbag. The air inside the airbag is then transmitted through the connecting tube to the pipe located at the bottom, allowing the aromatherapy to diffuse more quickly.

[0028] This invention can automatically sweep away dust from the bottom of the bed, avoiding the time-consuming and laborious process of manually bending over to clean. It can also integrate the aromatherapy function inside the bed frame, allowing for aromatherapy sleep aid directly within the bed frame, saving space and improving ease of use.

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0046] Example 1

[0047] Reference Figures 1-15 An adjustable-height soft bed includes: a bed frame body 1, a support leg 2 fixedly mounted on the bottom front side of the bed frame body 1, a support leg 6 mounted on the rear side of the bed frame body 1, a backrest 5 fixedly connected to the top of the support leg 6, a soft cushion mounted on the front side of the backrest 5, and multiple support plates 3 disposed inside the bed frame body 1. Multiple bed boards 4 are connected to the top of the multiple support plates 3, and a support column 7 is mounted at the bottom of each of the middle support plates 3.

[0048] The height adjustment mechanism is respectively installed in support leg 1 2, support leg 2 6 and support column 7, and is used to adjust the height of the bed frame body 1;

[0049] A stabilizing mechanism, installed on pillar 7, is used to increase stability;

[0050] A dust cleaning mechanism is located at the bottom of the backrest 5 and is used to clean dust and debris from the bottom of the bed frame body 1.

[0051] The avoidance mechanism, installed on the dust cleaning mechanism, is used to automatically avoid the support column 7 at the bottom of the bed;

[0052] An aromatherapy sleep aid mechanism is installed inside the main body of the bed frame 1 to improve sleep quality;

[0053] An auxiliary device is installed within the aromatherapy sleep aid device;

[0054] The replacement mechanism, located on the aromatherapy sleep aid device, is used to replace the scented tablets with different aromas.

[0055] Reference Figure 2 , Figure 3 and Figure 13 The height adjustment mechanism includes a screw 8 rotatably disposed inside the support column 7. A U-shaped push plate 80 is threadedly connected to the screw 8, and the U-shaped push plate 80 is slidably connected to the support column 7. The top end of the U-shaped push plate 80 is fixedly connected to the support plate 3. A bevel gear 9 is fixedly connected to the top outer surface of the screw 8. The bevel gear 9 meshes with a bevel gear 10. A rotating column 11 is fixedly connected to the front end of the bevel gear 10. The rotating column 11 extends through the front of the support column 7 to the outside of the support column 7. By rotating the two support legs 2... The rotating column 11 on one side of the two support legs 6 and the two pillars 7 can drive the bevel gear 10 to rotate, and through linkage, it can drive the U-shaped push plate 80 to move upward, thereby adjusting the overall height; the lead angle of the thread pair between the screw 8 and the U-shaped push plate 80 is ≤15°, and the thread friction coefficient should be controlled at ≥0.08 to ensure that the self-locking condition is met. When the friction coefficient is lower than 0.08, the self-locking function is reduced, and for small-sized threads such as M6, the self-locking ability may be completely lost, to prevent the bed frame from sinking unexpectedly due to self-locking failure.

[0056] Reference Figure 3 , Figure 12 and Figure 14The stabilizing mechanism includes a gear 18 connected to the outer surface of the bottom of the screw 18. Gear 18 is meshed with a gear 3 19, and gear 3 19 is meshed with a gear 2. Rotating columns 20 are fixedly connected to both gear 2 and gear 3 19. Rotating columns 20 are rotatably connected to the support column 7. Bevel gears 3 21 are fixedly connected to the outer surfaces of both rotating columns 20. Both bevel gears 3 21 are meshed with bevel gears 4 22. Rotating columns 3 23 are fixedly connected to the ends of both bevel gears 4 22 that are far apart from each other. Both rotating columns 3 23 are rotatably connected to the support column 7. Bevel gears 5 are fixedly connected to the ends of both rotating columns 3 23 that are far apart from each other. 24. Both bevel gears 24 are meshed with bevel gears 25. Positioning grooves 12 are fixedly opened on both the left and right sides of the support column 7. Rotating shafts 13 are rotatably connected inside the two positioning grooves 12. The two rotating shafts 13 are fixedly connected to the two bevel gears 25 respectively. U-shaped fixing plates 16 and T-shaped fixing plates 15 are slidably connected to the bottom of the support column 7. The U-shaped fixing plates 16 and T-shaped fixing plates 15 are compatible and can be spliced ​​into a cuboid to save space. The top of the U-shaped fixing plates 16 and T-shaped fixing plates 15 are fixedly provided with brackets 17 on the opposite sides. Two transmission plates 14 are rotatably connected between the two brackets 17 and the two rotating shafts 13.

[0057] Reference Figure 1 , Figure 4 and Figure 5 The dust cleaning mechanism includes a sliding block 27 located at the bottom of the backrest 5. A support block 26 is slidably connected to the outside of the sliding block 27. The support block 26 contacts the ground. A fixing groove is provided on the front side of the support block 26. Three hydraulic cylinders 28 are installed on the rear side of the inside of the fixing groove. The output ends of the three hydraulic cylinders 28 are slidably connected to two scraper blades 1 29 and scraper blade 2 35, respectively. Scraper blade 2 35 is located between the two scraper blades 1 29. A slider 33 is fixedly connected to the top of both scraper blades 1 29 and scraper blade 2 35. A spring 2 is fixedly connected to the top of the slider 33. A fixing block 34 is fixedly connected to the top of the spring 2. The slider 33 is slidably connected to the fixing block 34.

[0058] Reference Figure 4 and Figure 5The avoidance mechanism includes grooves 1 located on the sides of two scraper blades 29 that are close to each other. Spring plates 32 are connected to the sides of the two grooves 39 that are far apart. Triangular blocks 30 are fixedly connected to the ends of the two spring plates 32 that are close to each other, and the triangular blocks 30 are slidably connected to the grooves 1. Grooves 2 are formed on the left and right sides of scraper blade 35. Spring plates 2 are fixedly connected to the sides of the two grooves 2 that are close to each other. Triangular blocks 31 are fixedly connected to the ends of the two spring plates 2 that are far apart, and the triangular blocks 31 are slidably connected to the grooves 2. When the spring plate 32 and the two triangular blocks 31 contact the support column 7, they can press against each other, causing the two triangular blocks 30 to retract into the first groove and the two triangular blocks 31 to retract into the second groove, thus avoiding the support column 7. Since the front and rear sides of the two triangular blocks 30 and the two triangular blocks 31 are both inclined, with an angle of 45°±2°, jamming is avoided when the support column 7 contacts them. Therefore, whether scraping forward or retracting backward, the support column 7 can be avoided.

[0059] Reference Figure 1 , Figure 6 , Figure 7 and Figure 10The aromatherapy sleep aid mechanism includes multiple aromatherapy outlets 36 located on the left and right sides of the bed frame body 1. The outlets 36 gradually increase in size from the front to the back of the bed frame body 1, creating a gradient in the flow rate of the released aromatherapy gas. The smaller front outlets 36 release the gas at a faster flow rate, while the larger rear outlets release it at a relatively slower flow rate. This design not only helps the aromatherapy gas to diffuse evenly throughout the bedroom space but also enhances the layering of the aromatherapy experience, allowing the user to enjoy a more... A delicate and rich aromatherapy experience; simultaneously, the aromatherapy outlets 36 of different sizes can adjust the concentration and diffusion range of the aromatherapy according to the user's personal preferences and needs, achieving a personalized aromatherapy enjoyment; the bed frame body 1 has a connecting pipe 39 inside, and outlets 40 adapted to the aromatherapy outlets 36 are opened on both the left and right sides of the connecting pipe 39; a placement cavity 37 is set on the front side of the bed frame body 1, and two sections of pipe 38 are set inside the placement cavity 37, with a moving pipe 57 between the two sections of pipe 38. The moving pipe 57 has a filter inside, which can filter different aromatherapy products. The diffuser is placed on a magnetically secured filter made of neodymium iron boron (N52). This eliminates the need for tools, making cleaning or replacing the filter extremely convenient and greatly improving the user experience. The use of N52 neodymium iron boron ensures the filter's stability and durability due to its excellent magnetic properties and corrosion resistance. The high magnetic energy product of N52 allows the filter to be firmly adhered to the inside of the moving tube 57, maintaining a stable position even during the flow of aromatherapy gases, preventing the filter from falling off or shifting. The issue of aromatherapy gas leakage is addressed by the following: The top-mounted pipe 38 is connected to the connecting pipe 39. Each of the multiple bed boards 4 has two mounting slots on its top side. Each mounting slot has an airbag 41 on its bottom side. A pressure block 42 is slidably connected to each mounting slot. The top of each pressure block 42 is fixedly connected to the same top plate 43. The bottom of each airbag 41 has the same U-shaped tube 44. A connecting pipe 79 is fixedly connected to the bottom of the U-shaped tube 44. The bottom end of the connecting pipe 79 extends through the support plate 3 into the bottom-mounted pipe 38. The airbag 41 is made of TPU. The 95A TPU material has excellent elasticity and wear resistance, ensuring the stability and durability of the airbag 41 during use. At the same time, the moderate hardness of TPU 95A provides sufficient support while maintaining a soft and comfortable feel, bringing users a better sleep experience.

The knob 54 passes through the right side of the bed frame body 1 and is fixedly connected to a screw 55. A movable plate 56 is threaded onto the screw 55. The movable plate 56 is slidably connected to the bed frame body 1 and is fixedly connected to a movable tube 57. A connecting block 58 is fixedly connected to the front end of the movable tube 57, and a rack 59 is fixedly connected to the front end of the connecting block 58. A rotating column 52 is rotatably connected within the placement cavity 37. A gear 54 53 is fixedly connected to the rotating column 52. The gear 54 54 and the rack 59 are located on the same plane. A bevel gear 51 51 is fixedly connected to the top of the rotating column 52, and the bevel gear 51 meshes with a bevel gear 50. A bevel gear 50 50 is fixedly connected to... Rotating rod 2 49 is rotatably connected to the bed frame body 1. Both ends of rotating rod 2 49 are fixedly connected to bevel gear 8 48, which mesh with bevel gear 7 47. The rear ends of both bevel gear 7 47 are fixedly connected to rotating rod 1 46, which is rotatably connected to the bed frame body 1. Multiple sealing plates 1 45, adapted to the aromatherapy outlets 36, are fixedly connected to the outer surfaces of both rotating rods 1 46, and these sealing plates 1 45 rotate within the aromatherapy outlets 36 respectively. An electrospun nanofilm with a pore size ≤200nm and a dustproof efficiency of 99.7% is installed inside the aromatherapy outlets 36. Silicone sealing strips with a hardness of 60±5 Shore are provided around the sealing plates 1 45. A. The airtightness is improved by 50%, effectively preventing dust and odors from entering the bed frame through the aromatherapy outlet 36, maintaining a clean and comfortable environment inside the bed frame; at the same time, the use of silicone sealing strips not only enhances the fit between the sealing plate 45 and the aromatherapy outlet 36, but also further improves the overall airtightness of the bed frame, providing users with a better sleep experience.

[0061] Reference Figure 1 , Figure 7 and Figure 8The replacement mechanism includes a rotating rod 61 rotatably disposed inside the placement cavity 37. A gear 60 is fixedly connected to the outer surface of the rotating rod 61. An outlet is provided on the left side of the placement cavity 37, and a recycling trough is provided at the bottom of the outlet.

The first stage involves rotating the rack 59 until it separates from the gear 43, which closes multiple sealing plates 45 to prevent dust or other debris from clogging the aromatherapy outlet 36 when not in use. The second stage involves the moving tube 57 driving the rack 59 to continue moving, engaging the rack 59 with the gear 50, and then moving until the rack 59 separates from the gear 50. In this stage, the multiple sealing plates 45 remain closed, and through linkage, the sealing plate 2 64 opens. Continuing to move the tube 57 further out allows for the replacement of different aromatherapy items on the filter. Then, the moving tube 57 returns to its original position, closing the sealing plate 2 64 sequentially and reopening the multiple sealing plates 45.

[0062] This embodiment also proposes a method for using a soft bed with an adjustable bed frame height, including the following steps:

[0063] S1: By rotating the rotating column 11 on one side of the support leg 6 and the support column 7, the rotating column 11 drives the bevel gear 10 to rotate, the bevel gear 10 drives the bevel gear 9 to rotate, and the bevel gear 9 drives the screw 8 to rotate, which in turn drives the U-shaped push plate 80 to move upward. At the same time, as the U-shaped push plate 80 moves upward, it pushes the bed frame body 1, backrest 5, support plate 3 and bed board 4 to rise synchronously, thus adjusting the overall height until it reaches the height required by the user. During the adjustment process, due to the meshing design of the bevel gear 9 and the bevel gear 10, the stability and accuracy of the rotation are ensured, making the height adjustment more precise and stable. When the bed frame body is adjusted to the appropriate height, the rotating column 11 is stopped. The screw 8 has self-locking properties and can maintain the current position without changing, preventing the bed frame body 1 from accidentally falling due to gravity or other external forces, thereby ensuring the stability and safety of the height of the bed frame body 1.

[0064] S2: While adjusting the height, the screw 18 inside the support column 7 drives the gear 18 to rotate, the gear 18 drives the gear 319 to rotate, the gear 319 drives another gear 2 to rotate, and even if the two rotating columns 20 rotate at the same time, the two rotating columns 20 drive the two bevel gears 321 to rotate, the two bevel gears 321 drive the two bevel gears 422 to rotate, the two bevel gears 422 drive the two rotating columns 33 to rotate, so that the two rotating columns 323 drive the two bevel gears 524 to rotate, the two bevel gears 524 drive the two bevel gears 625 to rotate, so that the two bevel gears 625 drive the two rotating shafts 13 to rotate, that is, through the two transmission plates 14, the T-shaped fixing plate 15 and the U-shaped fixing plate 16 are unfolded. After the T-shaped fixing plate 15 and the U-shaped fixing plate 16 are unfolded, the contact area between the support column 7 and the ground can be increased, thereby effectively improving the overall stability of the bed frame body 1;

[0065] S3: When there is a lot of dust under the bed, activate the three hydraulic cylinders 28. The output ends of the three hydraulic cylinders 28 push the two scrapers 29 and 35 respectively, causing the two scrapers 29 and 35 to leave the fixing groove. At this time, the springs 2 inside the three fixing blocks 34 rebound, causing the two scrapers 29 and 35 to contact the ground. Then, continue to activate the three hydraulic cylinders 28 to push the dust under the bed to the outside of the bed. When it comes into contact with the support column 7, the two triangular blocks 30 and 31 squeeze the spring plates 32 and 31 respectively, thereby avoiding the support column 7 and pushing the garbage out of the bed. When the support column 7 is moved away, the spring plate 2 and spring plate 1 32 rebound, causing the two triangular blocks 1 30 and the two triangular blocks 2 31 to return to their original positions. At this time, the three hydraulic cylinders 28 are activated to sweep away the garbage at the bottom of the bed. Since the front and rear sides of the two triangular blocks 1 30 and the two triangular blocks 2 31 are inclined, it will not affect the forward movement for cleaning or the backward movement for recycling. Moreover, the bottom of the front side of the fixed groove is inclined, so during the recycling process, the inclined side of the fixed groove can squeeze the three springs 2 in the three fixed blocks 34 to rebound and recycle them into the fixed groove.

[0066] S4: By rotating the knob 54, the knob 54 drives the screw 2 55 to rotate, the screw 2 55 drives the moving plate 56 to move, that is, drives the moving tube 57 to move to the left, so that the rack 59 meshes with the gear 4 53, and drives the gear 4 53 to rotate. The rotation of the gear 4 53 drives the rotating column 52 to rotate, the rotating column 52 drives the bevel gear 10 51 to rotate, the bevel gear 10 51 drives the bevel gear 9 50 to rotate, the bevel gear 9 50 drives the rotating rod 2 49 to rotate, the rotating rod 2 49 drives the two bevel gears 8 48 to rotate, so that the two bevel gears 7 47 drive the two rotating rods 1 46 to rotate, thus closing the sealing plate 1 45;

[0067] S5: Then continue to rotate the knob 54, so that the moving plate 56 drives the moving tube 57 to move to the left, so that the rack 59 meshes with the gear 60, which drives the rotating rod 61 to rotate, so that the rotating rod 61 drives one of the sprockets 62 to rotate, and one of the sprockets 62 drives the other sprocket 62 to rotate through the chain 66, so that the screw 63 drives the sliding plate 65 to move downward, so that the sealing plate 64 is opened. At this time, the fragrance inside the moving tube 57 is replaced.

[0068] S6: After replacement, rotate knob 54 in the opposite direction to return moving tube 57 to its original position. Then, when someone sits or lies on the bed, a momentary force will push the top plate 43 and pressure block 42 downward, causing pressure block 42 to squeeze airbag 41. The air in airbag 41 is then transmitted through connecting tube 79 to pipe 38 at the bottom. Even if the aroma diffuses faster, the squeezing action of airbag 41 makes the aroma diffuse more quickly and fully, enhancing the aroma's effect. In addition, this design cleverly utilizes the pressure generated by human body weight to achieve automatic aroma diffusion without additional electricity or manual operation, making it energy-saving, environmentally friendly, convenient, and quick.

[0069] Example 2

[0070] The difference between this embodiment and Embodiment 1 is that: a dehumidification mechanism is provided at one end of the front interior of the bed frame body 1. The dehumidification mechanism includes a dehumidification box 67, which contains a processing area 68 and a dehumidification area 69. An air inlet is provided on the rear interior side of the dehumidification area 69, and a filter screen 76 is installed inside the air inlet. An air outlet is provided on the front interior side of the dehumidification area 69, and a filter screen 78 is installed inside the air outlet. A motor 70 is provided on the front interior side of the dehumidification area 69. A rotating shaft 71 is fixedly connected to the output shaft of the motor 70. A fan blade 72 is fixedly connected to the outer surface of the rotating shaft 71. A gearbox is fixedly connected to the rear end of the fan blade 72, and a rotating shaft 73 is fixedly connected to the output end of the gearbox. A dehumidifying material 75 is fixedly connected to the rear end of the rotating shaft 73. A connecting plate 77 is connected to both the dehumidification zone 69 and the treatment zone 68. The connecting plate 77 is slidably connected to the dehumidifying material 75. A heater 74 is installed on the front side of the treatment zone 68. By starting the heater 74 and the motor 70, the output shaft of the motor 70 drives the rotating shaft 71 to rotate. The rotating shaft 71 drives the fan blade 72 to rotate. The rotation of the fan blade 72 can draw the moisture from the bottom of the bed into the dehumidification zone 69, and the moisture is absorbed by the dehumidifying material 75. Then the dry air is discharged through the filter screen 78. At the same time, the fan blade 72 drives the rotating shaft 73 to rotate, and the rotating shaft 73 drives the dehumidifying material 75 to rotate. This allows the side of the dehumidifying material 75 containing moisture to rotate into the treatment zone 68, where the moisture is evaporated by the heat generated by the heater 74.

[0071] Example 3

[0072] The difference between this embodiment and embodiment one is that: each of the multiple support plates 3 is rotatably connected to a screw four, the rear ends of the multiple screw fours extend through the support block 26 and the backrest 5 to the rear side of the backrest 5 and are fixedly connected to a crank handle, and a sliding plate is threaded onto the screw four. Each of the multiple support plates 3 has a sliding groove on its inner right side, and the multiple sliding plates are slidably connected to the sliding groove. Each of the multiple sliding plates passes through the multiple sliding groove and is fixedly connected to an L-shaped plate. The multiple L-shaped plates are fixedly connected to the top of the three fixing blocks 34. By manually rotating the four crank handles, the four crank handles drive the screw four to rotate, causing the screw four to move the multiple sliding plates, which in turn push the fixing blocks 34 to move, thus pushing out the garbage under the bed.

[0073] Example 4

[0074] The difference between this embodiment and Embodiment 1 is that: a motor is installed on the inner bottom side of the support column 7, and the output shaft of the motor is fixedly connected to the screw 8. By starting the motor, the screw 8 is rotated, which in turn moves the U-shaped push plate 80 upward, thereby adjusting the overall height. The T-shaped fixing plate 15 is made of shape memory alloy SMA, which can automatically unfold, increasing the speed by three times and eliminating the need for manual operation. At the same time, the automatic unfolding characteristic of the T-shaped fixing plate 15 makes the bed frame more stable when adjusting the height, effectively preventing the bed frame from shaking and improving the safety of use. In addition, the use of shape memory alloy SMA allows the T-shaped fixing plate 15 to maintain good elasticity and resilience during long-term use, extending the service life of the bed frame.

[0075] A second motor is fixedly installed at the front right side of the bed frame body 1. The output shaft of the second motor is fixedly connected to the second screw 55. By starting the second motor, the output shaft of the second motor drives the second screw 55 to rotate, which can automatically control the opening and closing of the second sealing plate 64 and the first sealing plate 45 with an accuracy of ±0.1mm. It supports APP preset. Users can preset the opening or closing time of the second sealing plate 64 and the first sealing plate 45 according to actual needs on the APP. After receiving the instruction, the second motor can automatically and accurately control the rotation angle of the second screw 55, thereby driving the second sealing plate 64 and the first sealing plate 45 to perform precise opening or closing operations. This design not only improves the convenience of use, but also ensures the accuracy of operation, bringing users a more intelligent user experience.

[0076] An MEMS micropump and a concentration sensor are installed inside the moving tube 57, which improves the uniformity of aromatherapy by 40%. The MEMS micropump can precisely control the amount of aromatherapy liquid sprayed to ensure the uniform distribution of aromatherapy, while the concentration sensor monitors the concentration of aromatherapy in real time. When the concentration is lower than the preset value, the MEMS micropump is automatically activated to replenish it, so as to always maintain the stability of the aromatherapy concentration in the room. This design not only improves the uniformity of aromatherapy, but also brings a more lasting and stable aromatherapy experience. At the same time, through the APP preset function, users can set the concentration and duration of aromatherapy according to their personal preferences to achieve intelligent aromatherapy management.

[0077] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

A method of using a soft bed with an adjustable bed frame height, wherein the soft bed with an adjustable bed frame height is the soft bed with an adjustable bed frame height as described in any one of claims 1-9, characterized in that: Includes the following steps: S1: By rotating the second support leg (6) and the rotating column (11) on one side of the support column (7), the rotating column (11) drives the second bevel gear (10) to rotate, the second bevel gear (10) drives the first bevel gear (9) to rotate, the first bevel gear (9) drives the first screw (8) to rotate, that is, it drives the U-shaped push plate (80) to move upward. At the same time, during the upward movement of the U-shaped push plate (80), it will push the bed frame body (1), backrest (5), support plate (3) and bed board (4) to rise synchronously, that is, adjust the overall height, straight The height is adjusted to the user's desired height. During the adjustment process, the meshing design of bevel gear 1 (9) and bevel gear 2 (10) ensures the stability and accuracy of the rotation, making the height adjustment more precise and stable. When the bed frame body is adjusted to the appropriate height, the rotation of rotating column 1 (11) is stopped. Screw 1 (8) has self-locking properties and can maintain its current position without change, thus preventing the bed frame body (1) from falling unexpectedly due to gravity or other external forces, thereby ensuring the stability and safety of the height of the bed frame body (1). S2: While adjusting the height, the screw 1 (8) inside the support column (7) drives gear 1 (18) to rotate, gear 1 (18) drives gear 3 (19) to rotate, gear 3 (19) drives another gear 2 to rotate, even if the two rotating columns 2 (20) rotate at the same time, the two rotating columns 2 (20) drive the two bevel gears 3 (21) to rotate, the two bevel gears 3 (21) drive the two bevel gears 4 (22) to rotate, the two bevel gears 4 (22) drive the two rotating columns 3 (23) to rotate, so that the two The rotating column three (23) drives the two bevel gears five (24) to rotate, and the two bevel gears five (24) drive the two bevel gears six (25) to rotate, so that the two bevel gears six (25) drive the two rotating shafts (13) to rotate. That is, through the two transmission plates (14), the T-shaped fixing plate (15) and the U-shaped fixing plate (16) are unfolded. After the T-shaped fixing plate (15) and the U-shaped fixing plate (16) are unfolded, the contact area between the support column (7) and the ground can be increased, thereby effectively improving the overall stability of the bed frame body (1). S3: When there is a lot of dust under the bed, start the three hydraulic cylinders (28). The output ends of the three hydraulic cylinders (28) push the two scraper blades (29) and (35) respectively, so that the two scraper blades (29) and (35) leave the fixed groove. At this time, the springs in the three fixed blocks (34) rebound and make the two scraper blades (29) and (35) contact the ground. Then continue to start the three hydraulic cylinders (28) to push the dust under the bed to the outside of the bed. When it comes into contact with the support column (7), the two triangular blocks (30) and (31) squeeze the spring plate (32) and (31) respectively, thereby avoiding the support column (7) and removing the dust. The trash under the bed is pushed out. When it is far away from the support (7), the spring plate 2 and spring plate 1 (32) rebound, so that the two triangular blocks 1 (30) and two triangular blocks 2 (31) return to their original positions. At this time, the three hydraulic cylinders (28) are started to sweep the trash under the bed out. Since the front and rear sides of the two triangular blocks 1 (30) and two triangular blocks 2 (31) are inclined, it will not affect the forward movement for cleaning or the backward movement for recycling. The bottom of the front side of the fixed groove is inclined, so during the recycling process, the three springs 2 in the three fixed blocks (34) can be squeezed by the inclined side of the fixed groove to rebound and be recycled into the fixed groove.

The rotation of the gear four (53) drives the rotating column (52) to rotate, the rotating column (52) drives the bevel gear ten (51) to rotate, the bevel gear ten (51) drives the bevel gear nine (50) to rotate, the bevel gear nine (50) drives the rotating rod two (49) to rotate, the rotating rod two (49) drives the two bevel gear eight (48) to rotate, so that the two bevel gear seven (47) drives the two rotating rod one (46) to rotate, thus closing the sealing plate one (45); S5: Then continue to rotate the knob (54), so that the moving plate (56) drives the moving tube (57) to move to the left, so that the rack (59) meshes with the gear five (60), that is, it drives the rotating rod three (61) to rotate, so that the rotating rod three (61) drives one of the sprockets one (62) to rotate, and one of the sprockets one (62) drives the other sprocket one (62) to rotate through the chain (66), so that the screw three (63) drives the sliding plate (65) to move downward, so that the sealing plate two (64) is opened. At this time, the fragrance inside the moving tube (57) is replaced. S6: After the replacement is completed, rotate the knob (54) in the opposite direction to return the moving tube (57) to its original position. Then, when someone sits or lies on the bed, the instantaneous force will push the top plate (43) and the pressure block (42) downward, causing the pressure block (42) to squeeze the airbag (41). The air in the airbag (41) will be transmitted through the connecting tube (79) to the pipe (38) located at the bottom. Even if the aroma diffuses faster, the squeezing action of the airbag (41) makes the aroma diffuse more quickly and fully, enhancing the aroma effect. In addition, the design cleverly utilizes the pressure generated by the weight of the human body to achieve automatic aroma diffusion without the need for additional electricity or manual operation. It is energy-saving, environmentally friendly, convenient and fast.
