[0022] Compared with the prior art, the advantages of this invention are:

[0023] This design incorporates a lifting mechanism. In its normal state, the second drying rod rests on the first drying rod and is retracted beneath the main body. The main body then presses the lifting mechanism firmly, ensuring a seamless fit between the first and second drying rods, thus preserving their aesthetic appeal. When the second drying rod needs to be retrieved, the clothes dryer is activated, causing it to descend. The spring in the lifting mechanism naturally releases, driving the gear set and causing a push rod to lift the second drying rod upwards, allowing the user to easily lift it for use.

[0024] This solution features a transmission mechanism consisting of gear sets, which connects the trigger end and the lifting end. When the trigger end moves, it drives the gear set to mesh and transmit power, thereby accelerating the movement of the lifting end. This allows the lifting end to move faster and over a longer distance, thus lifting the second drying rack a greater distance, making it easier for the user to pick up and use it.

[0043] It is worth mentioning that the fixing between the two ends of the connecting seat 21 and the drying assembly can be fastened and connected by screws, or the connecting hook bodies 29 can be arranged on the front and rear side end faces of the connecting seat 21, the connecting hook bodies 29 are in the shape of a hook, and the connecting hook bodies 29 extend into the first drying rod 13 to form a hook connection, and the hook connection is more convenient for disassembly and assembly between the connecting seat 21 and the first drying rod 13.

[0044] The first drying rod 13 and the second drying rod 14 are both telescopic, the first drying rod 13 is slidably provided with a first extension rod 17, and the second drying rod 14 is slidably provided with a second extension rod 18. The end of the first extension rod 17 is fixedly provided with an end seat 41, the end seat 41 is slidably provided with a turnover device, and one end of the turnover device is rotatably provided with the second extension rod 18.

[0045] It can be understood that the first extension rod 17 is an internal rod of the first drying rod 13, the first extension rod 17 can be accommodated in the first drying rod 13, and the first extension rod 17 can be pulled out and slid out of the first drying rod 13 as an extension when needed, and the second extension rod 18 is an internal rod of the second drying rod 14, which is also accommodated in the second drying rod 14 and can be pulled out. The left and right ends of the first extension rod 17 on the front and rear sides are fixedly provided with end seats 41 respectively, and the end seats 41 are located on the left and right sides of the main body 11. The left and right ends of the second extension rod 18 on the front and rear sides are connected to the two end seats 41 through the turnover device respectively.

[0046] The turnover device includes a swing rod 42, a connecting shaft 43 and a sliding block 44, the swing rod 42 and the second extension rod 18 are fixedly provided, a horizontal sliding groove is formed in the end seat 41, the sliding block 44 is slidably arranged in the sliding groove in the horizontal direction, the connecting shaft 43 penetrates the swing rod 42 and the sliding block 44, and the swing rod 42 and the sliding block 44 are rotatably connected through the connecting shaft 43. Through the above connection, the second extension rod 18 can slide horizontally and also rotate, so that the second extension rod 18 can be turned over to be below the first extension rod 17 for drying quilts, or be turned over to be above the first extension rod 17 for resting.

[0047] The lifting assembly 200 is arranged at the two side end positions in the connecting seat 21, the lifting assembly 200 includes a lifting end extending to the upper side of the connecting seat 21 and a trigger end, the lifting end is arranged at a position directly below the second drying rod 14, and the trigger end is arranged at a position directly below the main body 11; a transmission mechanism is arranged between the lifting end and the trigger end, and the transmission mechanism controls the lifting end and the trigger end to move synchronously in the same direction.

[0048] It can be understood that the above-mentioned connecting seat 21 corresponds to the position of the shears frame 12 respectively provided with left and right two, and the above-mentioned lifting assembly 200 is respectively arranged at the front and rear positions of each connecting seat 21. Among them, the lifting end corresponds to the position of the second drying rod 14 to be arranged directly below the second drying rod 14. It is worth noting that the second drying rod 14 here refers to the position state when the second drying rod 14 is placed on the first drying rod 13. When the second drying rod 14 is placed on the first drying rod 13, the lifting end moves upward to synchronously drive the second drying rod 14 to move upward. The trigger end is arranged directly below the main body 11 corresponding to the position of the main body 11. When the shears frame 12 is retracted to control the connecting seat 21 to move upward, the trigger end will contact the main body 11 to be pressed downward, and the trigger end is pressed to drive the transmission mechanism to move, thereby synchronously driving the lifting end to move downward.

[0049] The connecting seat 21 is provided with a transmission cavity 34, and the lifting assembly 200 is arranged in the transmission cavity 34; wherein the trigger end comprises a trigger block 23, a first rack 25 and a spring 26 which are sequentially and fixedly arranged from top to bottom, the top end of the trigger block 23 extends to the upper side of the connecting seat 21, the top end of the first rack 25 is provided with a side end face of a tooth surface and is connected with the transmission mechanism, and the spring 26 is sleeved on the bottom end of the first rack 25. The bottom end of the spring 26 is fixedly arranged with the lower wall of the transmission cavity 34.

[0050] The lifting end comprises a lifting piece and a second rack 28 which are sequentially and fixedly arranged from top to bottom, and the top end of the lifting piece extends to the upper side of the connecting seat 21. The second rack 28 is provided with a side end face of a tooth surface and is connected with the transmission mechanism. The lifting piece comprises a push block 24 and a push rod 27, the push block 24 extends to the upper side of the connecting seat 21, and the push rod 27 is arranged on the side end face of the second rack 28 away from the tooth surface. A sliding plate 35 is arranged in the transmission cavity 34, the sliding plate 35 is fixedly arranged with the top end of the spring 26, and the trigger block 23, the push block 24 and the sliding plate 35 are all arranged to slide up and down on the inner wall of the transmission cavity 34.

[0051] It can be understood that the transmission cavity 34 is a hollow chamber arranged in the connecting seat 21, which is only used for accommodating the lifting assembly 200. The sliding plate 35 is a slidable plate arranged in the transmission cavity 34, the sliding plate 35 is fixed with the top end of the spring 26, and there is no contact between the sliding plate 35 and the second rack 28. The bottom end of the first rack 25 is fixedly arranged in a penetrating manner with the sliding plate 35. Therefore, the movement of the first rack 25 synchronously drives the sliding of the sliding plate 35, and when the trigger block 23 and the push block 24 are not in the pressed state, the spring 26 will push the sliding plate 35 to move upward.

[0052] The trigger end is composed of a trigger block 23, a first rack 25 and a spring 26. The trigger block 23 is arranged on the top end and extends above the connecting seat 21. When the trigger block 23 is in contact with the main body 11, it is pressed to move downward, thereby driving the first rack 25 to move downward, and driving the sliding plate 35 to move downward, and thereby compressing the spring 26 to be taut. The lifting end is composed of a push block 24, a push rod 27 and a second rack 28. The push block 24 extends above the connecting seat 21 like the trigger block 23. The push rod 27 is fixedly arranged on the side end face of the second rack 28 away from the tooth surface. The push block 24 and the push rod 27 are used for supporting or lifting the second drying rod 14.

[0053] The transmission mechanism includes a gear set arranged on the inner wall of the transmission cavity 34. The gears in the gear set are respectively in meshing transmission with the tooth surfaces of the first rack 25 and the second rack 28. The gear set is provided with at least three gears, and the gear set can be provided with a variable transmission ratio.

[0054] The gear set includes a driving gear 31, a driven gear 32 and a speed regulating gear 33. The driven gear 32 and the speed regulating gear 33 are coaxially arranged. The driving gear 31 and the driven gear 32 are in meshing transmission with each other. The driving gear 31 is in meshing transmission with the tooth surface of the first rack 25. The speed regulating gear 33 is in meshing transmission with the tooth surface of the second rack 28.

[0055] It can be understood that the above-mentioned gear set includes the driving gear 31 in meshing transmission with the first rack 25, the speed regulating gear 33 in meshing transmission with the second rack 28, and the driven gear 32 in meshing transmission with the driving gear 31. The driven gear 32 and the speed regulating gear 33 are coaxially arranged. The advantage of this arrangement is that the meshing transmission of the driving gear 31 and the driven gear 32 can control the moving direction of the first rack 25 and the second rack 28 to be consistent, and the moving speed of the second rack 28 in transmission can be controlled by selecting the diameter of the speed regulating gear 33, so as to realize the differential movement of the first rack 25 and the second rack 28. When the first rack 25 moves downward, it is in meshing transmission with the driving gear 31, thereby sequentially driving the driving gear 31, the driven gear 32 and the speed regulating gear 33 to rotate, thereby driving the second rack 28 to rotate in the same direction and at a differential speed.

[0056] The main body 11 is located on the side end of the second drying rod 14 in the vertical direction. The bottom end of the second drying rod 14 is provided with a clearance surface 36 located above the lowest surface of the second drying rod 14. The push rod 27 is in abutment with the clearance surface 36.

[0057] It is worth mentioning that the bottom surface of the second drying rod 14 is provided with a concave recess shape, the top end of the first drying rod 13 is provided with a drying hole 15, the drying hole 15 can be hung with a hanger body 16, and the recess shape is a displacement slot for accommodating the drying hole 15. At the same time, the bottom surface of the second drying rod 14 is also provided with a displacement surface 36, which is located on one side of the recess shape, and the displacement surface 36 is used to contact the push rod 27.

[0058] Working principle: in the initial state, the scissors frame 12 is in the contracted state, the connecting seat 21, the first drying rod 13 and the second drying rod 14 are located at the upper limit position, at this time the connecting seat 21 is at the shortest distance from the main machine body 11, the main machine body 11 presses down the trigger block 23, thereby tightening the spring 26, and through the transmission of the gear set, the push rod 27 is located at the lower limit position, at this time the second drying rod 14 is not pushed up and is placed on the first drying rod 13 in a pasting manner.

[0059] Specific use: when the hanger body 16 needs to be hung in the drying hole 15, or the second drying rod 14 needs to be turned over to dry the quilt, the built-in motor and controller in the main machine body 11 control the extension of the scissors frame 12, so that the connecting seat 21, the first drying rod 13 and the second drying rod 14 naturally move downward. When the first drying rod 13 and the second drying rod 14 move to the appropriate position, since the trigger block 23 does not continue to receive the downward pressure, the spring 26 is released to push the first rack 25 and the sliding plate 35 upward. After the first rack 25 is pushed upward, it is driven to rotate the driving gear 31 through the meshing transmission with the driving gear 31, thereby driving the driven gear 32 and the speed regulating gear 33 to rotate. Through the rotation of the speed regulating gear 33, the second rack 28 is synchronously moved upward. Since the diameters and gear ratios of the speed regulating gear 33 and the driven gear 32 are different, the upward movement speed of the second rack 28 is greater than that of the trigger block 23. Through the upward movement of the push block 24 and the push rod 27, the second drying rod 14 is pushed upward to no longer be placed on the first drying rod 13. Therefore, the user can easily pick up the second drying rod 14 and use it by turning it over.

[0060] When the second drying rod 14 is turned over for use, the sliding block 44 synchronously slides on the sliding groove on the end seat 41, and the swing rod 42 and the sliding block 44 can be arbitrarily rotated according to the angle of use through the connection of the connecting shaft 43.
