Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to a clothes drying device. Background Technology

[0002] Most basic clothes drying racks on the market rely on physical or digital remote controls to raise or lower the drying rod. However, if the physical or digital remote control malfunctions or fails, the drying rod will not be able to raise or lower properly. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the first aspect of this utility model proposes a clothes drying device.

[0005] In view of the above, according to the first aspect of the present invention, a clothes drying device is proposed, comprising: a clothes drying rod; a Bluetooth signal transmitting circuit disposed inside the clothes drying rod; the Bluetooth signal transmitting circuit includes a sensor and a Bluetooth communication module; the sensor is connected to the Bluetooth communication module; the sensor is used to sense external vibrations and generate corresponding electrical signals to enable the Bluetooth communication module to transmit Bluetooth signals; and a first controller, the first controller being communicatively connected to the Bluetooth communication module and used to receive the Bluetooth signals transmitted by the Bluetooth communication module to cause the clothes drying rod to rise or fall.

[0006] The clothes drying device provided by this utility model mainly includes: a first controller, a Bluetooth signal transmitting circuit, and a drying rod. The Bluetooth signal transmitting circuit is located inside the drying rod and includes a sensor and a Bluetooth communication module. The sensor and the Bluetooth communication module are electrically connected. When external vibration occurs, the sensor detects the vibration and generates a corresponding electrical signal. This electrical signal is then transmitted to the Bluetooth communication module. Upon receiving the electrical signal, the Bluetooth communication module transmits a preset Bluetooth key value signal, i.e., a Bluetooth signal. The drying rod supports clothing for drying. The drying rod can communicate with the first controller, which is also connected to the Bluetooth communication module in the Bluetooth signal transmitting circuit. When the first controller receives the Bluetooth signal transmitted by the Bluetooth communication module, it controls the drying rod to lower or raise. This utility model solves the problem in related technologies where the drying rod cannot be manually controlled when the physical or digital remote control fails. By incorporating a Bluetooth signal transmitting circuit into the clothes drying device, when the sensor in the Bluetooth signal transmitting circuit detects vibration in the drying device, the Bluetooth communication module in the Bluetooth signal transmitting circuit transmits a Bluetooth signal, causing the drying rod to lower or raise.

[0007] In some technical solutions, the Bluetooth signal transmitting circuit may optionally include: a signal processing circuit, the input terminal of which is connected to the output terminal of the sensor; and a second controller, the signal input pin of which is connected to the output terminal of the signal processing circuit, and the signal output pin of which is connected to the Bluetooth communication module.

[0008] In this technical solution, the Bluetooth signal transmitting circuit further includes a signal processing circuit and a second controller. The input terminal of the signal processing circuit is connected to the output terminal of the sensor. It is understood that the electrical signal generated by the sensor sensing external vibration is a chaotic pulse signal. Therefore, after the electrical signal is generated, the signal processing circuit needs to filter, tune, and couple the signal to transform it into a stable pulse signal. The signal input pin of the second controller is connected to the output terminal of the signal processing circuit, and the signal output pin of the second controller is connected to the Bluetooth communication module. When the signal input pin of the second controller receives the processed electrical signal, the signal output pin of the second controller outputs a signal to the Bluetooth communication module, enabling the Bluetooth communication module to transmit a Bluetooth signal. For example, when the second controller detects the first vibration-triggered pulse signal, it enters a wake-up preparation state. If the second controller detects a second vibration-triggered pulse signal within T seconds, and does not detect a third vibration-triggered pulse signal within the following T1 seconds, the second controller determines the vibration-triggered signal as valid. Subsequently, the second controller generates a fall command or a rise command to cause the Bluetooth communication module to transmit a Bluetooth signal. This invention transforms the chaotic electrical signals generated by the sensor into ordered pulse signals through a signal processing circuit. A second controller enables the Bluetooth communication module to transmit Bluetooth signals when the sensor detects movement in the clothes-drying device.

[0009] In some technical solutions, the signal processing circuit may optionally include: a filtering circuit, the input of which is connected to the output of the sensor; a coupling frequency selection circuit, the input of which is connected to the output of the filtering circuit; and a shaping circuit, the input of which is connected to the output of the coupling frequency selection circuit.

By using the second capacitor, its DC-blocking and AC-passing characteristics are utilized to filter out the DC offset component in the sensor output signal, thereby converting the chaotic original signal into a clean and regular electrical pulse. This ensures that the subsequent second controller can accurately and reliably identify the triggering intent, preventing false triggering.

[0015] In some technical solutions, optionally, the shaping circuit includes: a first transistor, the base of which is connected to the coupling frequency selection circuit, and the emitter of which is grounded; a second transistor, the base of which is connected to the collector of the first transistor, the emitter of which is grounded, and the collector of which is connected to a second controller; a second resistor, the first end of which is connected to the base of the first transistor and the coupling frequency selection circuit, and the second end of which is connected to a power supply; a third resistor, the first end of which is connected to the base of the second transistor and the collector of the first transistor, and the second end of which is connected to a power supply; and a fourth resistor, the first end of which is connected to the collector of the second transistor, and the second end of which is connected to a power supply.

[0016] In this technical solution, the shaping circuit includes: a first transistor, a second transistor, a second resistor, a third resistor, and a fourth resistor.

By setting up a shaping circuit with a first transistor, a second transistor, a second resistor, a third resistor, and a fourth resistor, the electrical signal generated by the sensor is shaped into a pulse electrical signal that meets the requirements of the signal input pin of the second controller.

Detailed Implementation

[0033] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0035] like Figure 1 As shown, this utility model proposes a clothes drying device 10, including: a drying rod 104, a Bluetooth signal transmitting circuit 102, the Bluetooth signal transmitting circuit 102 being disposed inside the drying rod 104, the Bluetooth signal transmitting circuit 102 including a sensor 106 and a Bluetooth communication module 108, the sensor 106 being connected to the Bluetooth communication module 108, the sensor 106 being used to sense external vibrations and generate corresponding electrical signals, so that the Bluetooth communication module 108 transmits Bluetooth signals; and a first controller 132, the first controller 132 being communicatively connected to the Bluetooth communication module 108, being used to receive the Bluetooth signals transmitted by the Bluetooth communication module 108, so that the drying rod 104 rises or falls.

[0036] The clothes drying device 10 provided by this utility model mainly includes: a first controller 132, a Bluetooth signal transmitting circuit 102, and a drying rod 104. The Bluetooth signal transmitting circuit 102 is disposed within the drying rod 104 and includes: a sensor 106 and a Bluetooth communication module 108. The sensor 106 is electrically connected to the Bluetooth communication module 108. When external vibration occurs, the sensor 106 senses the external vibration and generates a corresponding electrical signal. This electrical signal is then transmitted to the Bluetooth communication module 108. After receiving the electrical signal from the sensor 106, the Bluetooth communication module 108 transmits a preset Bluetooth key value signal, i.e., a Bluetooth signal. The drying rod 104 is used to support clothes for drying. The drying rod 104 can communicate with the first controller 132, and the first controller 132 can also communicate with the Bluetooth communication module 108 in the Bluetooth signal transmitting circuit 102. For example, the clothes drying device 10 consists of a main unit and the drying rod 104, and the main unit can control the drying rod 104 to operate. The Bluetooth signal transmitting circuit 102 is installed in the clothes drying rod, and the first controller 132 is installed in the main unit. When the Bluetooth signal transmitting circuit 102 detects that the clothes drying rod 104 is shaking (i.e., the sensor 106 in the Bluetooth signal transmitting circuit 102 senses external vibration), the Bluetooth communication module 108 in the Bluetooth signal transmitting circuit 102 will transmit a Bluetooth signal to the main unit. Then, the first controller 132 in the main unit will control the clothes drying rod 104 to operate. When the first controller 132 receives the Bluetooth signal transmitted by the Bluetooth communication module 108, it will control the clothes drying rod 104 to automatically lower or raise. This invention solves the problem in related technologies where the clothes drying rod 104 cannot be manually controlled when the physical remote control or digital remote control fails. By installing a Bluetooth signal transmitting circuit 102 in the clothes drying device 10, when the sensor 106 in the Bluetooth signal transmitting circuit 102 senses vibration in the clothes drying device 10, the Bluetooth communication module 108 in the Bluetooth signal transmitting circuit 102 will transmit a Bluetooth signal, causing the clothes drying rod 104 to lower or raise.

[0037] In some embodiments, optionally, such as Figure 2 As shown, the Bluetooth signal transmitting circuit 102 further includes: a signal processing circuit 110, the input terminal of which is connected to the output terminal of the sensor 106; and a second controller 112, the signal input pin 114 of which is connected to the output terminal of the signal processing circuit 110, and the signal output pin 116 of which is connected to the Bluetooth communication module 108.

[0038] In this embodiment, the Bluetooth signal transmitting circuit 102 further includes a signal processing circuit 110 and a second controller 112. The input terminal of the signal processing circuit 110 is connected to the output terminal of the sensor 106. It is understood that the electrical signal generated by the sensor 106 sensing external vibration is a chaotic pulse signal. Therefore, after the electrical signal is generated, the signal processing circuit 110 needs to filter, perform signal coupling, and process the signal to transform it into a stable pulse signal. The signal input pin 114 of the second controller 112 is connected to the output terminal of the signal processing circuit 110, and the signal output pin 116 of the second controller 112 is connected to the Bluetooth communication module 108. When the signal input pin 114 of the second controller 112 receives the electrical signal processed by the signal processing circuit 110, the signal output pin 116 of the second controller 112 outputs a signal to the Bluetooth communication module 108, enabling the Bluetooth communication module 108 to operate and transmit Bluetooth signals. For example, when the second controller 112 detects the pulse signal triggered by the first shaking, the second controller 112 enters a wake-up preparation state. If the second controller 112 detects the pulse signal triggered by the second shaking within T seconds, and does not detect the pulse signal triggered by the third shaking within the following T1 seconds, then the second controller 112 determines that the shaking trigger signal is a valid signal. Subsequently, the second controller 112 generates a fall command or a rise command to cause the Bluetooth communication module 108 to transmit a Bluetooth signal. This utility model uses a signal processing circuit 110 to transform the disordered electrical signal generated by the sensor 106 into an ordered pulse electrical signal. By configuring the second controller 112, the Bluetooth communication module 108 can transmit a Bluetooth signal when the sensor 106 detects shaking of the clothes drying device 10.

[0039] For example, the signal output pin 116 of the second controller 112 is connected to the Bluetooth communication module 108 through the seventh resistor R7 and the eighth resistor R8. At the same time, the end of the seventh resistor R7 near the signal output pin 116 of the second controller 112 is also connected to the first end of the fifth capacitor C5, and the second end of the fifth capacitor C5 is grounded to GND. The end of the eighth resistor R8 near the signal output pin 116 of the second controller 112 is also connected to the first end of the sixth capacitor C6, and the second end of the sixth capacitor C6 is grounded to GND.

[0040] For example, sensor 106 can be a high-sensitivity, omnidirectional patch vibration sensor. Sensor 106 remains closed or open when stationary, and outputs a pulse signal when it senses vibration, tilt, or movement. Since the pulse signal is disordered, it needs to be filtered, selected, and coupled to generate a stable control signal. The signal is then amplified and shaped by an amplifier circuit and transmitted to the signal input pin 114 of the second controller 112. The signal input pin 114 of the second controller 112 is set to interrupt wake-up mode. When an interrupt signal with a rising edge is received, the second controller 112 is woken up and sends a preset Bluetooth key value signal. Upon receiving the Bluetooth key value signal, the clothes dryer performs a lowering or raising operation on the drying rod 104. With this design, users do not need to rely on a physical or digital remote control; they only need to shake or vibrate the drying rod 104 to lower or raise it, making it convenient and quick to collect clothes.

[0041] In some embodiments, optionally, such as Figure 2 As shown, the signal processing circuit 110 includes: a filter circuit 118, the input terminal of which is connected to the output terminal of the sensor 106; a coupling frequency selection circuit 120, the input terminal of which is connected to the output terminal of the filter circuit 118; and a shaping circuit 124, the input terminal of which is connected to the output terminal of the coupling frequency selection circuit 120.

[0042] In this embodiment, the signal processing circuit 110 includes a filtering circuit 118, a coupling frequency selection circuit 120, and a shaping circuit 124. The input terminal of the filtering circuit 118 is connected to the output terminal of the sensor 106, and the filtering circuit 118 can filter the disordered electrical signals generated by the sensor 106. The output terminal of the filtering circuit 118 is connected to the input terminal of the coupling frequency selection circuit 120, and the coupling frequency selection circuit 120 can process the filtered electrical signals. For example, the filtering circuit 118 is connected to the coupling frequency selection circuit 120 through a tenth resistor R10. The input terminal of the shaping circuit 124 is connected to the output terminal of the coupling frequency selection circuit 120. For example, the shaping circuit 124 is connected to the second controller 112 through a sixth resistor R6, and the shaping circuit 124 shapes the processed electrical signals, converting them into stable electrical signals. This invention converts the chaotic electrical signal generated by the sensor 106 into a pulse electrical signal that meets the requirements of the signal input pin 114 of the second controller 112 by sequentially setting a filter circuit 118, a coupling frequency selection circuit 120, and a shaping circuit 124 in the signal processing circuit 110.

[0043] For example, such as Figure 3As shown, the Bluetooth signal transmitting circuit 102 of this utility model mainly includes a combination of a vibration sensor 106, a second controller 112, a filtering circuit 118, a coupling frequency selection circuit 120, and a shaping circuit 124. The vibration sensor 106 consists of a steel ball and a metal conductive layer. It detects environmental movements through the steel ball, and the constant switching on and off of the circuit due to the high and low resistance of the contact points generates irregular vibration pulse signals. The filtering circuit 118 is an RC filter and debouncing circuit. The irregular vibration pulse signal is delayed, debouncing, and filtered to remove noise, generating the pulse signal required for the shaking trigger. The coupling frequency selection circuit 120 removes the DC offset component from the filtered pulse signal. The signal shaping circuit 124 uses a transistor to shape the shaking-triggered signal, converting it into a stable signal and outputting a pulse signal that meets the requirements of the signal output pin 116 of the second controller 112.

[0044] The principle of this invention is as follows: the vibration sensor 106 receives external signals (such as displacement, vibration, acceleration, etc.) and converts them into electrical signals. After the signals are processed by the delay debouncing and filtering circuit 118, valid signals that meet the requirements of the second controller 112 are selected. Subsequently, the irregular waveform is converted into a pulse signal that can be recognized by the second controller 112 by the shaping circuit 124, and then transmitted to the second controller 112 for corresponding processing.

[0045] The processing logic of the second controller 112 determines that when the first shaking trigger pulse signal is detected, the second controller 112 enters the wake-up preparation state; if a second shaking trigger pulse signal is detected within T seconds, and no further trigger signal is detected within the following T1 seconds, the second controller 112 determines that the shaking trigger signal is a valid signal. Subsequently, the second controller 112 generates a descent command or an ascent command and sends it to the controller of the external automation system via a wireless signal to execute the corresponding command operation.

[0046] In some embodiments, optionally, such as Figure 3 and Figure 4 As shown, the filter circuit 118 includes: a first capacitor C1, the first end of which is connected to the first output terminal of the sensor 106, and the second end of which is connected to the second output terminal of the sensor 106; a first resistor R1, the first end of which is connected to the first end of the first capacitor C1 and the first output terminal of the sensor 106 respectively, and the second end of which is connected to the coupling frequency selection circuit 120.

[0047] In this embodiment, the filter circuit 118 includes a first capacitor C1 and a first resistor R1. The first terminal of the first capacitor C1 is connected to the first output terminal of the sensor 106, and the second terminal of the first capacitor C1 is connected to the second output terminal of the sensor 106. Simultaneously, the second terminal of the first capacitor C1 is grounded to GND, and the second output terminal of the sensor 106 is also grounded to GND. The first terminal of the first resistor R1 is connected to both the first terminal of the first capacitor C1 and the first output terminal of the sensor 106, and the second terminal of the first resistor R1 is connected to the coupling frequency selection circuit 120. By configuring the first resistor R1 and the first capacitor C1, the electrical signal generated by the sensor 106 is filtered.

[0048] In some embodiments, optionally, such as Figure 3 and Figure 4 As shown, the coupling frequency selection circuit 120 includes: a second capacitor C2, the first end of the second capacitor C2 is connected to the filter circuit 118, and the second end of the second capacitor C2 is connected to the shaping circuit 124.

[0049] In this embodiment, the coupling frequency selection circuit 120 includes a second capacitor C2. The first end of the second capacitor C2 is connected to the filter circuit 118, and the second end of the second capacitor C2 is connected to the shaping circuit 124. By setting the second capacitor C2, its DC-blocking and AC-passing characteristics are utilized to filter out the DC offset component in the output signal of the sensor 106, thereby converting the chaotic original signal into a clean and regular electrical pulse. This ensures that the subsequent second controller 112 can accurately and reliably identify the triggering intent, preventing false triggering.

The emitter of the second transistor Q2 is grounded to GND. The collector of the second transistor Q2 is connected to the input signal pin of the second controller 112 through the sixth resistor R6. The first end of the second resistor R2 is connected to the base of the first transistor Q1 and the coupling frequency selection circuit 120, respectively. The second end of the second resistor R2 is connected to the +3.3V power supply. The first end of the third resistor R3 is connected to the base of the second transistor Q2 and the collector of the first transistor Q1, respectively.
