[0036] To make the purpose, technical solution and advantages of the present application clearer, the following will further describe the implementation of the present application in detail with reference to the accompanying drawings. The clothes in the present application are all hung on the drying rod through hangers, and the clothes include but are not limited to clothes, towels, etc., which can be hung on hangers.

[0037] See also Figure 1 and Figure 2 As shown, an embodiment of the present application provides a clothes-drying rod assembly, including a movable clothes-drying rod 20 telescopically mounted on a main clothes-drying rod 10; the movable clothes-drying rod 20 is connected to a driving device 12, and is telescopically movable relative to the main clothes-drying rod 10 under the drive of the driving device 12.

[0038] In one embodiment, the main drying rod 10 can be made hollow, and a movable drying rod 20 is provided at each end along the length. The main drying rod 10 is provided with a movable drying rod 20 inside, and the movable drying rod 20 is driven by the driving device 12 to move along the length direction of the main drying rod 10.

[0039] Specifically, the driving device 12 includes a telescopic cylinder and a push rod; the telescopic cylinder is arranged on the main drying rod 10, and the movable drying rod 20 is arranged on the front end of the push rod; when the telescopic cylinder moves in a telescopic manner, it drives the push rod and the movable drying rod 20 to move in a straight line. Figure 1 The embodiment shown is one implementation of the telescopic cylinder.

[0040] In addition to the above implementation methods, the driving device 12 includes a driving chip and a motor; the driving chip is used to receive driving instructions and drive the motor to extend and retract the movable drying rod 20; the movable drying rod 20 is arranged on the motor output shaft, and the movable drying rod 20 moves in a straight line under the drive of the motor output shaft.

[0041] See also Figure 3 As shown, an embodiment of the present application provides a telescopic control device of a clothes-drying rod assembly as any of the above-mentioned items, including: a main clothes-drying rod 10 and a movable clothes-drying rod 20 telescopically installed on the main clothes-drying rod 10; the control device includes a controller 11, a driving device 12 and a clothing detection unit 21; the clothing detection unit 21 is arranged on the movable clothes-drying rod 20 and is connected to the controller 11, and is used to detect clothing information on the movable clothes-drying rod 20; the controller 11 is connected to the driving device 12, and is used to send a driving instruction to the driving device 12 according to the clothing information on the movable clothes-drying rod 20; the driving device 12 is driven and connected to the movable clothes-drying rod 20, and is used to control the movable clothes-drying rod 20 to telescope relative to the main clothes-drying rod 10 according to the driving instruction.

[0042] The clothing detection unit 21 detects whether there are clothes on the movable drying rod 20, which is clothing information.

[0043] In one embodiment, when the main drying rod 10 is lowered, the movable drying rod 20 changes from the contraction mode to the extension mode by default; when the main drying rod 10 is raised, when there is no clothes hanging on the movable drying rod 20, the movable drying rod 20 changes from the extension mode to the contraction mode, and when there are clothes hanging on the movable drying rod 20, the movable drying rod 20 remains in the extension mode.

[0044] Alternatively, the main drying rod 10 can rise or fall to keep the movable drying rod 20 in the retracted mode to meet the user's needs, and the movable drying rod 20 can be changed to the extended mode after the user has further needs; or, the main drying rod 10 can rise or fall to keep the movable drying rod 20 in the extended mode to meet the user's needs, and the movable drying rod 20 can be changed to the retracted mode after the user has further needs.

[0045] Specifically, the clothing detection unit 21 is a laser sensor, an infrared sensor or an ultrasonic sensor; the clothing detection unit 21 includes a transmitting end 211 and a receiving end 212, and the transmitting end 211 and the receiving end 212 are respectively located at the two ends of the movable drying rod 20; a groove or a hanging hole is arranged on the movable drying rod 20 to facilitate hanging a hanger to block the transmission of the signal; or, a blocking piece for blocking the transmission of the signal is arranged on the movable drying rod 20, and the blocking piece is triggered when the hanger is hung.

[0046] Among them, see Figure 4 As shown, the clothing detection unit 21 can use an infrared sensor here. The principle is that if there is no obstruction in the signal area, the receiving end 212 can normally receive the signal sent by the transmitting end 211; if there is an obstruction, the signal cannot be received normally. Therefore, the level of the receiving end 212 will change accordingly. By reading the level signal, it can be known whether there is an obstruction in the area. If there are clothes hanging on the movable drying rod 20, DO outputs a low level; if there are no clothes hanging on the movable drying rod 20, DO outputs a high level.

[0047] Correspondingly, a groove or a clothes hanging hole is provided on the movable clothes drying rod 20, and the groove or the clothes hanging hole can block the transmitted signal through the hanger. In one embodiment, a plurality of first clothes hanging holes 16 are provided on the main clothes drying rod 10; Figure 2 As shown, the movable airing rod 20 is provided with a plurality of second clothes-hanging holes 22; the spacing between each adjacent two first clothes-hanging holes 16 is equal to the spacing between each adjacent two second clothes-hanging holes 22. The shapes of the first clothes-hanging holes 16 and the second clothes-hanging holes 22 can be circular, semicircular, square, etc., and can also be set to have an upper opening. Since the movable airing rod 20 is provided with the second clothes-hanging holes 22, a clothes hanger can be directly hung on the movable airing rod 20 through the second clothes-hanging holes 22 for drying clothes. The presence of the plurality of second clothes-hanging holes 22 can prevent the clothes hanger from moving relative to the movable airing rod 20, thereby ensuring the stability of clothes hanging. Since the spacing between the adjacent two second clothes-hanging holes 22 is equal to the spacing between the adjacent two first clothes-hanging holes 16 on the main airing rod 10, when the movable airing rod 20 is retracted into the main airing rod 10, the second clothes-hanging holes 22 can be aligned with the first clothes-hanging holes 16, without affecting the hanging of clothes on the first clothes-hanging holes 16 of the main airing rod 10. Furthermore, at least one third clothes hanging hole 23 can be arranged between adjacent second clothes hanging holes 22 to increase the hanging capacity. The transmitting end 211 and the receiving end 212 are arranged at both ends of the movable clothes drying rod 20, and when a clothes hanger is hung, the signal path can be blocked.

[0048] Compared with the prior art method of setting a hook on the movable clothes-drying rod 20, the clothes-drying rod assembly can ensure the smoothness of the movable clothes-drying rod 20 when extending and retracting, and avoid noise. At the same time, directly processing the clothes-drying hole reduces the number of parts required for installation, which can reduce the failure rate of the clothes-drying rod assembly and reduce the frequency of maintenance.

[0049] A baffle for blocking signal transmission can also be set on the movable drying rod 20. The baffle is triggered when the clothes hanger is hung. The position of the baffle can be limited to the sending end 211, the receiving end 212 or the transmission signal path. The baffle is conducive to blocking the transmission of the signal more easily, thereby improving the accuracy of the clothing detection unit 21.

[0050] Specifically, in addition to the above situations, the clothing detection unit 21 can also be a weighing sensor or a pressure sensor; the clothing detection unit 21 is a weighing sensor, which is arranged in the drying area of ​​the movable drying rod 20; the clothing detection unit 21 is a pressure sensor, which is arranged on the surface of the drying area of ​​the movable drying rod 20.

[0051] In one embodiment, a gasket may be provided in the drying area of ​​the movable drying rod 20 for measurement by a weighing sensor or a pressure sensor, so that it can detect whether there are clothes hung on the movable drying rod 20 .

[0052] In addition to using the clothing information obtained by the clothing detection unit 21 to extend and retract the movable drying rod 20, it can also be controlled by the external terminal 50. Figure 5 As shown, a wireless communication module is connected to the controller 11; the controller 11 is connected to the clothes drying machine main controller 31 and / or the external terminal 50 through the wireless communication module, and the external terminal 50 includes a remote control and / or a smart terminal.

[0053] Among them, each external terminal 50 is a user device, and the external terminal 50 can be a smart terminal, various electronic devices with a display screen and supporting web browsing, such as: smart phones (such as Android phones, iOS phones, etc.), mobile phone simulators, tablet computers, laptops, digital broadcast receivers, MIDs (Mobile Internet Devices), PDAs (Personal Digital Assistants), and remote controls, etc.

[0054] In some embodiments, the external terminal 50 is a smart phone with an APP (application) installed. The length of the clothes-drying rod is set through the APP, which mainly refers to the threshold distance that the movable clothes-drying rod 20 can move. The extension distance refers to the length that the user considers most suitable for extension, that is, the preset extension length; the contraction distance refers to the length that the user considers most suitable for contraction, that is, the preset contraction distance. The specific APP operation is to select the extension distance in the operation box of the APP to set the extension length of the movable clothes-drying rod 20, which is the preferred extension distance, and select the contraction distance in the operation box of the APP to set the contraction length of the movable clothes-drying rod 20, which is the preferred contraction distance.

[0055] In some embodiments, the external terminal 50 is a remote controller. The remote controller is configured to send an extension instruction or a contraction instruction to the controller 11 or to the main controller 31. If the extension instruction is sent to the main controller 31, the main controller 31 transmits the instruction to the controller 11. If the extension instruction is sent directly to the controller 11, the transmission step can be omitted, so that the controller 11 controls the driving device 12 to drive the movable drying rod 20 to move to the extension distance based on the extension instruction, or the controller 11 controls the driving device 12 to drive the movable drying rod 20 to move to the contraction distance based on the contraction instruction; the extension instruction includes an extension preset distance, and the contraction instruction includes a contraction preset distance; the extension preset distance and the contraction preset distance are respectively used as the movable distance thresholds of the movable drying rod 20.

[0056] Whether the controller 11 directly receives the signal from the external terminal 50 can be set by the user.

[0057] Optionally, the controller 11 may also be provided with a voice module, which is used to receive the command words shouted by the user and play the response status. The embodiment of the present application is based on the function of the voice module reaching a specified distance, and it additionally has the recognized command words and response broadcasts as shown in the table.

[0058] Control Type Corpus Command response broadcast Stretch to a specified distance Stretch to zero point x meters (x: 0~5) Stretching to zero point x meters for you Shrink to a specified distance Shrink to zero point x meters (x: 0~5) Shrinking to zero x meters for you

[0059] For example, users can use voice to shout commands such as "stretch to 0.5 meters" to accurately reach the specified distance. This function based on the voice module to reach the specified distance greatly improves the user experience.

[0060] Specifically, the limit device 14 connected to the controller 11 includes at least one of: a contact switch and a distance measuring module; when the limit device 14 is a contact switch, it is arranged on the main drying rod 10 and on the telescopic path of the movable drying rod 20, and is used to detect whether the movable drying rod 20 has reached a fully extended and / or fully retracted state relative to the main drying rod 10; when the limit device 14 is a distance measuring module, it is arranged on the main drying rod 10, and is used to detect the distance between the movable drying rod 20 and the main drying rod 10, and judge whether the movable drying rod 20 has reached a fully extended and / or fully retracted state relative to the main drying rod 10 according to the distance.

[0061] In a possible embodiment, tracks can be set at both ends of the main drying rod 10 along the length, and a movable drying rod 20 can be set on the track. The movable drying rod 20 is set on the track to slide, and the movable drying rod 20 can be fixed at any position. The fixing method can be that the upper and lower or left and right sides of the movable drying rod 20 are connected with the inside of the main drying rod 10, that is, the movable drying rod 20 can be extended to any length.

[0062] The fully extended movable drying rod 20 corresponds to the extension threshold distance of the movable drying rod 20, and the fully retracted movable drying rod 20 corresponds to the contraction threshold distance of the movable drying rod 20. The movable drying rod 20 is contracted to the maximum safety distance. If it continues to contract, the movable drying rod 20 will press the controller 11, the driving device 12, etc. in the main drying rod 10, causing damage; the movable drying rod 20 is extended to the maximum safety distance. If it continues to extend, the movable drying rod 20 will fall off or cannot bear the weight of the clothes hung on the movable drying rod 20.

[0063] When the limit device 14 is a contact switch, if the distance from the inner end of the movable drying rod 20 to the starting position when the movable drying rod 20 is retracted is set to 5 cm, and the distance from the inner end of the movable drying rod 20 to the starting position when the movable drying rod 20 is extended is set to 50 cm, a contact switch is set at the corresponding position. When the controller 11 receives a signal from the limit device 14 during retraction, the drive device 12 is controlled to stop working; when the controller 11 receives a signal from the limit device 14 during extension, the drive device 12 is controlled to stop working.

[0064] When the limiting device 14 is a distance measurement module, such as an ultrasonic sensor, it includes: working voltage 3.3V-5V, working current 15mA, working frequency 40kHz, ranging range 2cm-4m, ultrasonic emission angle <15°, and the ranging module 15 can be a HC-SR04 ultrasonic ranging module. The overall working logic of the ranging module is that the controller 11 triggers the ranging module to start the measurement program, receives the ultrasonic ranging data in real time, organizes and packages the data into distances, and reports the data to the controller 11 through serial communication; the ranging module uses ultrasonic waves to send, and the ultrasonic waves touch the obstacles and reflect back. The ranging module receives the return signal of the ultrasonic wave, and outputs the distance level data according to the time difference between sending and receiving, and then according to the speed of sound, the ranging distance calculated by the internal chip.

[0065] See also Figure 6 As shown, a schematic diagram of a driving mode of ultrasonic ranging is shown. The controller 11 provides a 10us level to the ultrasonic ranging module as a starting ranging signal, and the ultrasonic ranging module automatically emits ultrasonic waves, that is, 8 40khz signals are sent out in a cycle, and the returned ultrasonic signals are analyzed, and finally an echo signal is output, and the echo signal is an echo level proportional to the detection distance.

[0066] In one example, the distance measuring module can measure the distance moved by the movable drying rod 20 in real time, and can control the movable drying rod 20 to reach a specified position through instructions. One of the problems solved by the telescopic control device of the drying rod assembly of the embodiment of the present application is that the movable drying rod 20 automatically and accurately reaches a specified distance.

[0067] Specifically, it also includes a distance measuring device 15, which is a Hall sensor, and the driving device 12 is a motor; the Hall sensor is arranged on the motor, and the Hall sensor detects the number of rotations of the motor; the controller 11 calculates the telescopic distance of the movable drying rod 20 according to the number of rotations of the motor.

[0068] The distance measuring device 15, that is, the Hall sensor, can be set on the motor, and there is no need to find a location to install it on the main drying rod 10. The number of rotations of the motor is detected, so as to calculate the telescopic distance of the movable drying rod 20 relative to the main drying rod 10. In order to avoid subsequent calculation errors, the Hall sensor can be used in conjunction with the contact switch of the limit device 14. It can be set that when the contact switch detects that the movable drying rod 20 is fully retracted, the Hall sensor is cleared. The distance measuring device 15 is connected to the controller 11 for communication, and the telescopic distance of the movable drying rod 20 is sent to the controller 11. It can be used to control the telescopic distance of the movable drying rod 20, and it can also be used to collect the telescopic distance of the movable drying rod 20, and then form the user's habit, which can be used as the default setting later. Among them, the controller 11 can be an MCU (Microcontroller Unit).

[0069] In a possible embodiment, the movable drying rods 20 at both ends can be set to move 0.2m. The controller 11 controls the movable drying rods 20 to the extension mode through the driving device 12 and moves to the position of 0.2m. The distance can be set and then verified using the distance measuring module. Then the controller 11 can count the moving distance and then take the moving distance that ranks first in the count order, which is the default for the user's habit.

[0070] See also Figure 7 As shown, the main controller 31 or the controller 11 can receive instructions from the voice module, APP, and remote control, and then the controller 11 converts the instructions into signals and transmits them to the driving device 12, the limiting device 14 and the distance measuring device 15. The driving device 12 is used to provide power for the movable drying rod 20, the distance measuring device 15 detects the distance moved by the movable drying rod 20 and feeds back to the controller 11, and the limiting device 14 detects whether the movable drying rod 20 is fully extended or retracted and feeds back to the controller 11.

[0071] Specifically, it also includes a power module 13 for power supply; the power module 13 is arranged in the main drying rod 10, and a charging port 131 of the power module 13 is arranged in the main drying rod 10, which is connected to the charging plug 32 on the clothes drying machine host 30 after the main drying rod 10 rises.

[0072] See also Figure 8 As shown, the present application also provides a clothes drying machine, comprising any of the above-mentioned clothes drying rod assemblies and any of the above-mentioned telescopic control devices. The host 30 is provided with a charging plug 32. When the steel wire rope 40 rises to the bottom of the host 30 and the power module 13 is low in power, the charging port 131 and the charging plug 32 can be automatically extended and electrically connected.

[0073] Another embodiment can also adopt wireless charging, which may include a power supply module and a power receiving module. The power supply module is arranged on the host 30, and the power receiving module is arranged on the main air-drying rod 10. The power supply module is configured as a wireless transmitter for wirelessly charging the wireless receiver. The wireless transmitter is fixed on the host 30, and the wireless receiver is fixed on the main air-drying rod 10. For example, the wireless receiver can be fixed on the bracket or the main air-drying rod 10, and corresponds to the position of the wireless transmitter. The wireless receiver is electrically connected to the power module 13. The wireless transmitter includes a power management circuit and a transmitter coil. The power management circuit is used to drive the transmitter coil to generate a charging magnetic field. The wireless receiver includes a rectifier circuit and a receiver coil adapted to the transmitter coil. The transmitter coil is fixed on the host 30, and the receiver coil is fixed on the main air-drying rod 10, and corresponds to the position of the transmitter coil, and receives the charging magnetic field to generate electric energy. The receiver coil is electrically connected to the power module 13 through the rectifier circuit, and the electricity rectified by the rectifier circuit is used to charge the power module 13. In the example, wireless charging is used to charge the receiver coil on the main drying rod 10 through the transmitter coil on the host 30. The wireless charging method eliminates the need for a plug structure or a cable structure. When the main drying rod 10 rises to the bottom of the host 30, the transmitter coil on the host 30 charges the receiver coil on the main drying rod 10.

[0074] The present application provides a movable air-drying rod 20 on the main air-drying rod 10, and the movable air-drying rod 10 is connected to a driving device 12, and the movable air-drying rod 20 is retracted and extended relative to the main air-drying rod 10 under the drive of the driving device 12, and the movable air-drying rod 20 is controlled to be retracted or extended by the driving device 12. The present application also provides a telescopic control device for an air-drying rod assembly, and a clothing detection unit 21 is provided on the movable air-drying rod 20. When there is no clothing to be dried on the movable air-drying rod 20, the controller 11 controls the movable air-drying rod 20 to be in a retracted mode; if there is clothing to be dried on the movable air-drying rod 20, the movable air-drying rod 20 remains in an extended mode. Thus, the air-drying rod is self-adaptive, which can not only improve the mounting capacity, but also improve the convenience. In addition, the extension distance of the movable air-drying rod 20 is adjustable, and the application range is wide, which can maintain the beauty and be easier to care for.
