[0082] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0083] Figure 1 FIG. 1 is a schematic structural diagram of a lifting device for a clothes drying rod 8 according to an exemplary embodiment of the present invention. Figure 2 for Figure 1 Another structural schematic diagram of the lifting device of the clothes drying rod 8 is shown, Figure 3 for Figure 1 A is an enlarged schematic diagram shown in FIG. Figure 1-Figure 3 As shown, the lifting device of the clothes drying rod 8 provided in this embodiment includes: a housing 11 and a motor 2 installed on the housing 11. Among them, the output end of the motor 2 is connected to a winding drum 3, and the winding drum 3 includes a first winding area 31 and a second winding area 32. Two first brackets 4 and two second brackets 5 are arranged on the housing 11, and the two first brackets 4 are respectively arranged on both sides of the output shaft of the motor 2, and the two second brackets 5 are respectively arranged on both sides of the output shaft of the motor 2. In a possible design, the output shaft of the motor 2 can also be used as a symmetric axis, and two first brackets 4 and two second brackets 5 are symmetrically arranged on the housing 11. The first brackets 4 on both sides of the housing 11 are provided with a wire pressing pulley 41, and the second brackets 5 on both sides of the housing 11 are provided with a limit pulley 51. The connecting wires 7 on the first winding area 31 and the second winding area 32 are respectively connected to one end of the clothes drying rod 8 after passing through the wire pressing pulley 41 and the limit pulley 51 on the corresponding side in sequence. When the motor 2 drives the winding drum 3 to rotate, the first winding area 31 and the second winding area 32 both reel in or release the connecting wire 7 .

[0084] It is worth understanding that when the motor 2 drives the winding drum 3 to rotate, in order to enable the first winding area 31 and the second winding area 32 to complete the action of coordinated winding or releasing the connecting line 7, the first winding area 31 and the second winding area 32 are one to wind up or unwind the wire from the upper end of the winding drum 3, and the other to wind up or unwind the wire from the lower end of the winding drum 3.

[0085] In this embodiment, the winding drum 3 is driven by the motor 2, so that the first winding area 31 and the second winding area 32 cooperate to reel in or release the connecting line 7, so that the clothes drying rod 8 can achieve the lifting function under the joint action of the connecting lines 7 connected at both ends of the clothes drying rod 8.

[0086] Considering that when clothes are hung on the clothes drying rod 8, they are heavy and require a power source with a large torque, the motor 2 in this embodiment can be selected as a tubular motor.

[0087] Based on the above embodiments, Figure 4 FIG. 1 is a schematic diagram of a lifting device for a clothes drying rod 8 in use according to an exemplary embodiment of the present invention. Figure 5 FIG. 8 is a schematic diagram of a clothes drying rod 8 lifting device in a retracted state according to an exemplary embodiment of the present invention. Figure 4-Figure 5 As shown, the shell 11 is also provided with an air outlet 12, and the air outlet 12 is provided with a first micro switch 6. When the motor 2 drives the winding drum 3 to rotate to reel in the connecting wire 7, when the clothes drying rod 8 triggers the first micro switch 6, the first micro switch 6 sends a termination instruction to the controller, so that the controller controls the motor 2 to stop rotating.

[0088] In actual use, when the clothes drying rod 8 assembly rises, the tubular motor is controlled by a pre-set program, and after being turned on, it rotates to drive the winding drum 3 to rotate, thereby tightening the connecting wire 7. The connecting wire 7 moves upward through the wire pressing pulley 41 and the limit pulley 51. When it rises to the corresponding position, the first micro switch 6 is activated. The first micro switch 6 gives a signal to the controller, so that the controller controls the tubular motor to stop working, and the clothes drying rod 8 assembly stops at this position.

[0089] In addition, a clothes-drying rod 8 accommodating groove is provided on the air outlet portion 12 , and the first micro switch 6 is disposed in the clothes-drying rod 8 accommodating groove. When the clothes-drying rod 8 triggers the first micro switch 6 , the clothes-drying rod 8 is embedded in the clothes-drying rod 8 accommodating groove.

[0090] The wind source of the air outlet 12 may be a centrifugal fan, which has a large wind pressure and is conducive to drying the clothes hung on the clothes drying rod 8 .

[0091] Continue to refer to Figure 3 , the rotating shaft of the pressing pulley 41 and the first bracket 4 are provided with a pressing spring 91 along the lifting direction of the clothes drying rod 8, and the rotating shaft of the pressing pulley 41 moves between the first position and the second position, wherein the connecting line 7 at the first position and the second position is parallel to the lifting direction of the clothes drying rod 8. When the rotating shaft of the pressing pulley 41 is located at the first position, the pressing spring 91 is in a stretched state, and the pressing pulley 41 presses the connecting line 7; when the rotating shaft of the pressing pulley 41 is located at the second position, the pressing spring 91 recovers from the stretched state to a free state. In addition, a second micro switch 92 is provided on the first bracket 4, and when the rotating shaft of the pressing pulley 41 is separated from the first position and moves to the second position, the state of the second micro switch 92 changes, and the second micro switch 92 sends a termination instruction to the controller, so that the controller controls the motor 2 to stop rotating.

[0092] In actual use, when the clothes drying rod 8 descends, the tubular motor is controlled by a preset program. After it is turned on, it rotates to drive the winding drum 3 to rotate, thereby releasing the connecting wire 7. Under the action of gravity of the clothes drying rod 8, the connecting wire 7 moves downward through the wire pressing pulley 41 and the limit pulley 51. When the clothes drying rod 8 component encounters an obstacle on the way down, the second micro switch 92 is immediately triggered. The second micro switch 92 gives a signal to the controller, so that the controller controls the tubular motor to stop working, and the clothes drying rod 8 stops at this position.

[0093] After the clothes-drying rod 8 lifting device receives the rising instruction, it can be automatically determined by setting a weight sensor whether to directly raise the clothes-drying rod 8 to the top or to stop the clothes-drying rod 8 at a certain height, so that the air outlet 12 can effectively dry the clothes hung on the clothes-drying rod 8, wherein the rising instruction can be a rising instruction input through a control panel or other control methods. Specifically, the weight sensor is used to obtain the weight of the connecting line 7, and whether the weight obtained by the weight sensor exceeds a preset threshold value is determined to determine whether there are clothes hung on the clothes-drying rod 8, wherein the threshold value can be set as the weight of the clothes-drying rod 8. When it is determined that there are clothes hung on the clothes-drying rod 8, after the clothes-drying rod 8 lifting device receives the rising instruction, the clothes-drying rod 8 is stopped at a certain height, so that the air outlet 12 can effectively dry the clothes hung on the clothes-drying rod 8; and when it is determined that there are no clothes hung on the clothes-drying rod 8, after the clothes-drying rod 8 lifting device receives the rising instruction, the clothes-drying rod 8 is directly raised to the top.

[0094] The following is an explanation of the clothes drying rod structure in the above embodiment. Figure 6 FIG. 1 is a schematic exploded view of the structure of a clothes drying rod according to an exemplary embodiment of the present invention. Figure 7 FIG. 1 is a schematic diagram of the structural assembly of a clothes drying rod according to an exemplary embodiment of the present invention. Figure 8 for Figure 6 The enlarged view of the clothes drying rod B is shown. Fig. 9 FIG. 1 is a schematic diagram showing the structure of a rod sleeve according to an exemplary embodiment of the present invention. Fig.10 for Fig. 9 The structural cross-sectional diagram of the rod sleeve is shown in FIG. Figure 6-Figure 10As shown, the clothes drying rod includes: a rod body 81, a rod sleeve, a limiting part and a connecting line. A rod sleeve cavity 834 is provided on the rod sleeve, and rod sleeves are respectively sleeved at both ends of the rod body 81. The end of the rod body 81 is inserted into the rod sleeve cavity, and a guide hole 831 is provided on the side wall of the rod sleeve away from the end of the rod body. The rod sleeve is provided with a wire outlet 832 along the direction of the rod body 81, and a receiving groove 833 is provided at the bottom of the rod sleeve. The receiving groove 833 is used to receive the limiting part. It is worth noting that one end of the connecting line 7 is connected to the limiting part, and the outer diameter of the limiting part is smaller than the inner diameter of the guide hole 831, and the outer diameter of the limiting part is larger than the width of the wire outlet 832, so that the limiting part is inserted into the receiving groove 833 through the guide hole 831, and the connecting line passes through the wire outlet 832.

[0095] It is worth understanding that the rod body 11 is usually suspended at both ends, so the rod sleeve includes: a first rod sleeve 82 and a second rod sleeve 83. It is worth noting that the first rod sleeve 82 and the second rod sleeve 83 can be the same structure or different structures. In actual design, in order to save costs, it is preferred to set the first rod sleeve 82 and the second rod sleeve 83 to the same structure.

[0096] In addition, the limiting portion includes a first limiting portion 86 and a second limiting portion 87 .

[0097] The following describes the connection relationship between one side of the second rod sleeve 83 and the rod body 81 and the connecting line 7 to describe the clothes drying rod connection structure provided in this embodiment. When the first rod sleeve 82 is configured to have the same structure as the second rod sleeve 83, the principles are the same. The details are as follows:

[0098] The second rod sleeve 83 is provided with a rod sleeve cavity 834, the end of the rod body 81 is inserted into the rod sleeve cavity 834, and a guide hole 831 is provided on the side wall of the second rod sleeve 83 away from the end of the rod body 81, and the second rod sleeve 83 is provided with a wire outlet 832 along the direction of the rod body 81, and a receiving groove 833 is provided at the bottom of the second rod sleeve 83, and the receiving groove 833 is used to receive the second limiting portion 87. Among them, one end of the connecting line 7 is connected to the second limiting portion 87, the outer diameter of the second limiting portion 87 is smaller than the inner diameter of the guide hole 831, and the outer diameter of the second limiting portion 87 is larger than the width of the wire outlet 832, so that the second limiting portion 87 is inserted into the receiving groove 833 through the guide hole 831, and the connecting line 7 passes through the wire outlet 832.

[0099] A rod sleeve cavity is provided on the rod sleeve, and rod sleeves are respectively sleeved at both ends of the rod body, and the ends of the rod body are inserted into the rod sleeve cavities. In addition, a guide hole is provided on the side wall of the rod sleeve away from the end of the rod body, and a wire outlet portion is provided on the rod sleeve along the direction of the rod body. A accommodating groove is provided at the bottom of the rod sleeve, and the accommodating groove is used to accommodate a limiting portion, and one end of the connecting rope is connected to the limiting portion, wherein the outer diameter of the limiting portion is smaller than the inner diameter of the guide hole, and the outer diameter of the limiting portion is larger than the width of the wire outlet portion. When the limiting portion is inserted into the accommodating groove through the guide hole, the connecting rope passes out from the wire outlet portion. During installation, the limiting portion is clamped in the rod sleeve by utilizing the gravity when the rod body is suspended and the size setting of the structure. During disassembly, the disassembly can be completed by directly detaching the limiting portion from the rod sleeve, which greatly simplifies the disassembly and installation process of the clothes drying rod and does not take up too much space.

[0100] In order to effectively restrict the circumferential displacement between the rod body 81 and the rod sleeve when the rod body 81 is matched with the rod sleeve, an end limit groove 811 is opened on the side wall of the end of the rod body 81, and a limit card 836 is provided on the inner wall of the rod sleeve cavity 134. When the end of the rod body 81 is inserted into the rod sleeve cavity 834, the limit card 136 is clamped in the end limit groove 811 to limit the circumferential displacement between the rod body 81 and the rod sleeve.

[0101] In addition, in order to effectively restrain the axial displacement between the rod body 81 and the rod sleeve when the rod body 81 is matched with the rod sleeve, an end threaded hole 812 can be provided on the end of the rod body 81, and a mounting hole 835 is provided at the bottom of the rod sleeve cavity 834. When the end of the rod body 81 is inserted into the rod sleeve cavity 834, the threaded hole 812 is coaxial with the mounting hole 835, so that the screw can pass through the mounting hole 835 to form a threaded connection with the threaded hole 812, thereby restraining the axial displacement between the rod body 81 and the rod sleeve.

[0102] In order to reduce the weight of the rod body 81, the rod body 81 can be configured to include: an outer rod body, an inner rod body and a rod body connecting plate, the outer rod body and the inner rod body are coaxially arranged, the rod body connecting plate is used to connect the outer rod body and the inner rod body in the radial direction, and the end limit groove 811 is opened on the end side wall of the outer rod body, and the end threaded hole 812 is opened at the end of the inner rod body. It is worth noting that in order to save manufacturing costs, a profile of a corresponding shape can also be selected for the rod body 81, and the profile only needs to be cut to a specified length.

[0103] The limiting portion may be set as a sphere. In addition, the specific shape of the limiting portion may also be an ellipsoid, a cylinder, or an object of other shapes. The specific shape of the limiting portion is not limited in this embodiment.

[0104] In a possible design, the guide hole 831 may be set to be circular. In addition, the specific shape of the guide hole 831 may also be elliptical, square, or other shapes. The specific shape of the guide hole 831 is not limited in this embodiment.

[0105] Fig.11 FIG. 1 is a schematic diagram showing a structure of a connecting line according to an exemplary embodiment of the present invention. Fig.11 As shown, for the connection between the limiting part and the connecting wire, a threaded hole can be opened on the limiting part, and a mounting part 841 is provided at the end of the connecting wire used for connecting with the limiting part, and a mounting external thread 8411 is provided on the outer side of the mounting part 841. When the limiting part is connected to the connecting wire, the mounting external thread 8411 cooperates with the threaded hole to be connected.

Figure 12-13 As shown, in order to prevent the hanger hung on the rod body 81 from sliding freely within the entire rod body 81 and causing the piled clothes to be difficult to dry, an anti-slip portion can also be provided along the length direction of the rod body 81.

[0108] As for the specific structure of the anti-slip part, in a possible design, an anti-slip installation hole 813 may be opened along the length direction of the rod body 81, and an anti-slip installation hole 813 is clamped with an anti-slip member 814, and the anti-slip member 814 is arranged on the side wall of the rod body 81 facing the connecting rope. Among them, the anti-slip installation holes 813 may be evenly arranged along the length direction of the rod body 81.
