[0050] Referring to Figure 1 and Figure 2 , an embodiment of the present application provides a clothes drying host, which comprises a fixed body 10 and a movable body 30, the movable body 30 is movably connected with the fixed body 10, so that the movable body 30 can move relative to the fixed body 10, thereby realizing the unfolding and folding of the body.

[0051] Specifically, the movable body 30 is rotatable relative to the fixed body 10 about a rotation axis, and the movable body 30 is formed with a movable air outlet 42, when the movable body 30 is completely folded with the fixed body 10, as shown in Figure 1 , the movable air outlet 42 is located between the movable body 30 and the fixed body 10, so that the clothes drying host after folding can not only realize the reduction of space, but also realize the closing of the movable air outlet 42, avoiding the entry of external dust and sundries into the movable air outlet 42 to cause blockage, thereby affecting the air outlet effect.

[0052] When the movable body 30 rotates relative to the fixed body 10 by a certain angle, the clothes drying host can be in an unfolded state, as shown in Figure 2 . During the movement of the movable clothes drying host relative to the fixed body 10, the orientation of the movable air outlet 42 changes with the movement of the movable clothes drying host, and when the clothes drying host is in a completely unfolded state, as shown in Figure 2 , the orientation of the movable air outlet 42 is vertical when the clothes drying host is placed on a horizontal plane.

[0053] In actual use, the fully unfolded drying main body is arranged below the drying cover of the drying machine, so that the movable air outlet 42 can face the clothes hung on the drying cover, and the hot air discharged through the movable air outlet 42 can dry the clothes on the drying cover.

[0054] Please refer to Figure 5 and Figure 6 In order to enable the movable air outlet 42 to discharge hot air, the movable heating element 41 and the movable air blower and other components are arranged on the movable body 30, so that the air flow generated by the movable air blower passes through the movable heating element 41 and is heated to form hot air, which is discharged from the movable air outlet 42.

[0055] In order to supply power to the movable heating element 41 and the movable air blower and other components, the power supply module 21 is arranged on the fixed body 10, and the power supply module 21 is used to be connected with an external power source such as a power grid. Moreover, the power supply module 21 is also electrically connected with the movable heating element 41 and the air blower motor for driving the movable air blower, so that the power supply module 21 distributes the power of the power grid to the movable heating element 41 and the air blower motor.

[0056] Among them, the air blower motor is arranged on the fixed body 10 and connected with the movable air blower on the movable body 30 through a transmission shaft, and the transmission shaft can move relative to the fixed body 10 with the movement of the movable body 30, so that after the movable body 30 moves relative to the fixed body 10, the transmission shaft can also realize the driving of the air blower motor to the movable air blower.

[0057] It should be noted that the transmission shaft can move relative to the fixed body 10 with the movement of the movable body 30 means that the transmission shaft can adapt to the movement of the movable body 30 relative to the fixed body 10 to ensure the transmission connection between the air blower motor and the movable air blower. In the embodiment of Figure 2 , the movable body 30 is rotatably arranged on the fixed body 10 about a rotation axis, and the axis of the transmission shaft is coaxial with the rotation axis, so that during the rotation of the movable body 30 relative to the fixed body 10, the transmission shaft can also rotate together to adapt to the position of the movable body 30. In other embodiments, when the movable body 30 is arranged on the fixed body 10 in an extendable manner, the transmission shaft can extend and retract relative to the fixed body 10 together with the movable body 30.

[0058] The movable heating element 41 is arranged on the movable body 30. If the power supply module 21 is directly connected to the movable heating element 41 through a wire, the wire will move together with the movable heating element 41 during the movement of the movable body 30 relative to the fixed body 10, thus causing various problems such as wire pinching, wire hanging, wire cutting, and wire stretching. Not only can the wire body be easily damaged, but also the wire body can affect the rotation of the movable body 30, resulting in the drying machine main body being unable to rotate to an unfolded state or being unable to recover to a folded state.

[0059] To this end, referring to Figure 3 and Figure 4 , the fixed body 10 has a fixed contact 11; the movable body 30 has a movable contact 31; the movable body 30 has an unfolded position and a folded position during the movement of the movable body 30 relative to the fixed body 10. When the movable body 30 is located at the unfolded position, the movable contact 31 is in contact with the fixed contact 11, and the two are electrically connected to each other. When the movable body 30 is located at the folded position, the movable contact 31 is separated from the fixed contact 11.

[0060] The movable heating element 41 is electrically connected to the movable contact 31, and the power supply module 21 is electrically connected to the fixed contact 11. In this way, when the movable body 30 moves relative to the fixed body 10 to the unfolded position, the movable contact 31 is electrically connected to the fixed contact 11, and the power supply module 21 and the movable heating element 41 are electrically connected to each other. At this time, the movable heating element 41 starts to work, and the air blown out of the movable air outlet 42 is hot air.

[0061] When the movable body 30 moves relative to the fixed body 10 to the folded position, the movable contact 31 and the fixed contact 11 are disconnected from each other, and the power supply module 21 and the movable heating element 41 are disconnected from each other. The movable heating element 41 stops working, and the air blown out of the movable air outlet 42 is cold air.

[0062] In this way, through the electrical connection of the movable contact 31 and the fixed contact 11, only when the user unfolds the drying machine, the movable heating element 41 will start to work, and the movable air outlet 42 can blow out hot air for drying. When the user rotates the movable body 30, i.e., when the user needs to start folding the drying machine, the movable contact 31 will be separated from the fixed contact 11, so that the air blown out of the movable air outlet 42 is only natural air, so as to avoid the influence of hot air on the drying machine or the user due to the change of the position of the movable air outlet 42 after folding.

[0063] Since the movable body 30 and the fixed body 10 are electrically connected to each other through the movable contact 31 and the fixed contact 11, during the rotation of the movable body 30 relative to the fixed body 10, the wires inside the movable body 30 and the fixed body 10 remain stationary relative to themselves and are not affected by the movement of the movable body 30, avoiding problems such as wire pinching, wire hanging, wire cutting, and wire tensioning, and ensuring the normal movement of the movable body 30 relative to the fixed body 10, thereby improving the service life of the clothes drying main machine.

[0064] It can be understood that the movable contact 31 described above can be connected to the movable heating element 41, but is not limited to this. In other embodiments, the air blowing motor can also be arranged on the movable body 30, and the air blowing motor is electrically connected to the movable contact 31, so that when the movable body 30 moves to the unfolded state, the air blowing motor can be electrically connected to the power supply module 21, and the movable air outlet 42 can output air flow. When the movable body 30 moves to the folded position, the air blowing motor and the power supply module 21 are disconnected from each other, and the movable air outlet 42 stops outputting air flow. That is, in this embodiment, when the clothes drying main machine is unfolded, the movable air outlet 42 automatically outputs air, and when the clothes drying machine is folded, the movable air outlet 42 automatically closes.

[0065] In some embodiments of the present application, referring to Figure 8 and Figure 9 , the fixed contact 11 includes a plurality of fixed contacts, and all the movable contacts 31 are arranged in a first direction, and the first direction intersects the movement direction of the movable body 30 relative to the fixed body 10. In Figure 5 , the movement direction of the movable body 30 relative to the fixed body 10 is the circumferential direction around the rotation axis, and the first direction is the radial direction. The movable contact 31 includes a plurality of movable contacts, each movable contact 31 is in contact with one of the fixed contacts 11 when the movable body 30 is in the unfolded position, and each movable contact 31 is separated from all the fixed contacts 11 when the movable body 30 is in the folded position.

[0066] In actual use, the movable heating element 41 has a positive electrode and a negative electrode, and both the positive electrode and the negative electrode need to be electrically connected to the power supply module 21. Therefore, the positive electrode and the negative electrode can be respectively in contact with one of the movable contacts 31, and the two movable contacts 31 and the two fixed contacts 11 are used to electrically connect the positive electrode and the negative electrode to the power supply module 21.

[0067] Specifically, all the fixed contacts 11 include a first fixed contact 12 and a second fixed contact 13, and all the movable contacts 31 include a first movable contact 32 and a second movable contact 33. When the movable body 30 is in the unfolded position, the first fixed contact 12 is in contact with the first movable contact 32, and the second fixed contact 13 is in contact with the second movable contact 33.

[0068] The movable body 30 comprises a movable heating element 41, the movable heating element 41 comprises a positive terminal and a negative terminal, the positive terminal is electrically connected with the first movable contact 32, and the negative terminal is electrically connected with the second movable contact 33. The fixed body 10 comprises a power supply module 21, the power supply module 21 has an X1 power supply terminal and a zero line terminal, the X1 power supply terminal is electrically connected with the first fixed contact 12, and the zero line terminal is electrically connected with the second fixed contact 13.

[0069] The X1 power supply terminal is used for being connected with a live wire of an external power grid, the zero line terminal is used for being connected with a zero line of the external power grid, when the movable body 30 is located at the unfolded position, the current of the live wire is input to the first fixed contact 12 through the X1 power supply terminal, the first fixed contact 12 inputs the current to the first movable contact 32, finally, the current is input to the movable heating element 41 through the first movable contact 32, so that the movable heating element 41 is driven to generate heat. After the current passes through the movable heating element 41, the current passes through the second movable contact 33, the first fixed contact 12, the zero line terminal and finally returns to the zero line in sequence, so that the closed loop of the circuit is completed.

[0070] In some embodiments, all the fixed contacts 11 further comprise a third fixed contact 14, and the power supply module 21 further comprises an X2 power supply terminal, the X2 power supply terminal can also be connected with the live wire of the external power grid. All the movable contacts 31 further comprise a third movable contact 34, when the movable body 30 is located at the unfolded position, the third fixed contact 14 is in contact with the third movable contact 34. The movable body 30 comprises two movable heating elements 41, the positive terminal of one of the movable heating elements 41 is electrically connected with the first movable contact 32, and the positive terminal of the other movable heating element is electrically connected with the third movable contact 34, and the negative terminal of each movable heating element 41 is electrically connected with the second movable contact 33.

[0071] In this way, when the movable body 30 is located at the unfolded position, the two movable heating elements 41 can simultaneously input the airflow of the movable air outlet 42 for heating, so that the temperature of the airflow discharged from the movable air outlet 42 is higher, thereby effectively improving the drying efficiency of the clothes.

[0072] It should be noted that the movable body 30 comprising two movable heating elements 41 means that the movable body 30 at least has two movable heating elements 41, that is, the number of the movable heating elements 41 can also be three, four or more. In addition, the plurality of movable contacts 31 can also comprise a fourth movable contact 31 and a fifth movable contact 31, and the plurality of fixed contacts 11 can also comprise a fourth fixed contact 11 and a fifth fixed contact 11, so that the third and fourth movable heating elements 41 can also be electrically connected with the power supply module 21 through one of the movable contacts 31 and the fixed movable contacts 31.

[0073] In some embodiments of the present application, the movable body 30 has a movable air outlet 42, and the fixed body 10 has a fixed air outlet 23. When the movable body 30 is in the unfolded position, the fixed air outlet 23 is parallel to the direction of the movable air outlet 42. That is, when the movable body 30 is in the unfolded position, the fixed air outlet 23 and the movable air outlet 42 are both directed in the vertical direction, so that when the clothes drying main machine is used to dry clothes, the clothes can be dried by air blowing out of the fixed air outlet 23 and the movable air outlet 42 at the same time, thereby improving the range and efficiency of clothes drying.

[0074] In order to make the air blown out of the fixed air outlet 23 hot air, the fixed body 10 is also provided with a fixed heating element 22. The fixed heating element 22 also has a positive electrode and a negative electrode. The positive electrode of the fixed heating element 22 is directly connected to the X1 power supply terminal or the X2 power supply terminal of the power supply module 21, and the negative electrode is connected to the zero line terminal. Since the fixed heating element 22 is arranged on the fixed body 10, the movement of the movable body 30 will not affect the connection between the fixed heating element 22 and the power supply module 21,

[0075] Further, the fixed heating element 22 also includes two, one of which has a positive electrode connected to the X1 power supply terminal, and the other has a positive electrode connected to the X2 power supply terminal. The negative electrode of each fixed heating element 22 is connected to the zero line terminal, so as to improve the hot air temperature of the fixed air outlet 23 by two fixed heating elements 22.

[0076] In some embodiments of the present application, the fixed body 10 includes a fixed shell 20 and a fixed contact spring 15 mounted on the fixed shell 20. The fixed contact spring 15 has a fixed contact 11 formed thereon. When the movable body 30 is in the unfolded position, the fixed contact spring 15 is compressed between the fixed shell 20 and the movable contact 31.

[0077] In this way, when the movable body 30 is in the unfolded position, the fixed contact spring 15 will be compressed, so that the fixed contact spring 15 can form a stable contact with the movable contact 31 through the elastic force of the fixed contact spring 15 itself, thereby ensuring that the movable heating element 41 and the power supply module 21 can achieve stable electrical connection.

[0078] Further, the movable body 30 includes a movable shell 40 and a movable contact spring 35 mounted on the movable shell 40. The movable contact spring 35 has a movable contact 31 formed thereon. When the movable body 30 is in the unfolded position, the movable contact spring 35 is compressed between the movable shell 40 and the fixed contact 11, so as to realize stable electrical connection between the movable heating element 41 and the power supply module 21 through the contact between the movable contact spring 35 and the fixed contact spring 15.

[0079] It can be understood that the movable contact spring 35 and the fixed contact spring 15 can be required, and only one of them is provided, such as only the fixed contact spring 15 is provided, and the movable contact 31 is directly formed on the outer surface of the movable shell 40, and only the fixed contact spring 15 can complete the stable connection of the fixed contact 11 and the movable contact 31.

[0080] In some embodiments, the fixed shell 20 is provided with a guide groove 24, and the movable shell 40 is provided with a guide portion 43. During the movement of the movable shell 30 relative to the fixed shell 10, the guide portion 43 can move along the guide groove 24, so that the guide groove 24 guides the guide portion 43, and the movement of the movable shell 30 relative to the fixed shell 10 in a specified direction is realized. When the movable shell 30 rotates around a rotation axis of the fixed shell 10, the guide portion 43 and the guide groove 24 are both arc-shaped structures, so that the dryer can be switched between the two states of 180° expansion and folding,

[0081] In some embodiments, the fixed contact 11 is located on the inner wall of the guide groove 24, and the movable contact 31 is located on the guide portion 43. In this way, during the movement of the movable shell 30 relative to the fixed shell 10, the guide portion 43 moves in the guide groove 24, thereby driving the movable contact 31 to move relative to the fixed contact 11, until the movable shell 30 moves to the expanded position, and the movable contact 31 abuts against the fixed contact 11.

[0082] It can be understood that in other embodiments, the fixed shell 20 can be provided with a guide portion 43, and the movable shell 30 can be provided with a guide groove 24. The fixed contact 11 is located on the guide portion 43, and the movable contact 31 is located on the inner wall of the guide groove 24.

[0083] Further, referring to Figure 7 and Figure 10 The fixed shell 10 further comprises a fixed mounting seat 16, and the fixed mounting seat 16 is provided with a plurality of fixed elastic contact pieces. Each fixed elastic contact piece is formed with a fixed contact 11. The fixed mounting hole 17 is formed on the inner wall of the guide groove 24, and the fixed mounting seat 16 is arranged in the fixed mounting hole 17, so that each fixed elastic contact piece can extend into the guide groove 24, and the fixed contact 11 can abut against the fixed contact 11 on the guide portion 43.

[0084] Further, the movable body 30 further comprises a movable mounting base 36, and a plurality of movable elastic contact pieces are arranged on the movable mounting base 36, and each movable elastic contact piece is formed with a movable contact point 31. An activity mounting hole 37 is arranged on the inner wall of the guide groove 24, and the movable mounting base 36 is arranged in the activity mounting hole 37, so that each movable elastic contact piece protrudes from the guide portion 43, and the movable contact point 31 can abut against the movable contact point 31 on the inner wall of the guide groove 24.

[0085] In some embodiments, the guide groove 24 has an opening 25 at one end in the longitudinal direction of the guide groove 24, and at least part of the guide portion 43 can exit the guide groove 24 through the opening 25 during the movement of the movable body 30 relative to the fixed body 10 from the unfolded position to the folded position. In actual use, as long as part of the guide portion 43 is located in the guide groove 24, the guide groove 24 can guide the guide portion 43, so that the length of the guide groove 24 can be reduced while ensuring the guiding effect, thereby reducing the volume of the fixed shell 20.

[0086] Specifically, referring to Figure 5 When the movable body 30 moves counterclockwise relative to the fixed body 10, the guide groove 24 remains stationary, and the guide portion 43 moves clockwise in the guide groove 24. When the movable body 30 is in the unfolded position, the opening 25 is arranged at one end of the guide groove 24 facing the movable body 30, and when the guide portion 43 moves clockwise in the guide groove 24, the guide portion 43 exits the guide groove 24 from the opening 25, until the guide portion 43 exits the guide groove 24 completely, or the movable body 30 moves to the folded position and cannot continue to move.

[0087] In order to ensure the reliability of the contact between the fixed contact point 11 and the movable contact point 31, the thickness of the movable elastic contact piece protruding from the outer surface of the guide portion 43 is greater than half the gap between the guide groove 24 and the outer surface of the guide portion 43, and the thickness of the fixed elastic contact piece protruding from the inner wall of the fixed groove is greater than half the gap between the outer surface of the guide portion 43.

[0088] In actual use, the inner wall of the guide groove 24 is a smooth surface, and the surface of the guide portion 43 further protrudes with a reinforcing rib 44, in order to avoid interference between the reinforcing rib 44 and the fixed elastic contact piece. In some embodiments, when the movable body 30 is in the unfolded position, all the guide portions 43 are located in the guide groove 24, the fixed contact point 11 is located at one end of the guide groove 24 away from the opening 25, the movable contact point 31 is located at one end of the guide portion 43 away from the opening 25, and the reinforcing rib 44 is located on the side of the movable contact point 31 from the unfolded position to the folded position, i.e. the reinforcing rib 44 is located on the side of the movable contact point 31 facing the opening 25.

[0089] Thus, when the movable body 30 moves relative to the fixed body 10 from the unfolded position to the folded position, the movable contact 31 and the reinforcing rib 44 will move together towards the opening 25, i.e. the movable contact 31 and the reinforcing rib 44 will move away from the fixed contact 11, and the reinforcing rib 44 will not contact the fixed contact 11, thereby avoiding the problem of friction between the reinforcing rib 44 and the fixed contact 11, affecting the conductivity and contact efficiency of the fixed contact 11.

[0090] The above-described clothes drying main machine has at least the following advantages:

[0091] Since the movable body 30 and the fixed body 10 are electrically connected to each other through the movable contact 31 and the fixed contact 11, during the rotation of the movable body 30 relative to the fixed body 10, the wires inside the movable body 30 and the fixed body 10 will all remain stationary relative to themselves and will not be affected by the movement of the movable body 30, thereby avoiding problems such as wire clamping, wire hanging, wire cutting, and wire tensioning, ensuring the normal movement of the movable body 30 relative to the fixed body 10 and improving the service life of the clothes drying main machine.

[0092] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.

[0093] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
