The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

FIG. 1 is a schematic view of one embodiment of a carding machine provided herein, which may include a machine body. A control module 101 may be included in the device body, and a light detection module 102 connected to the control module 101.

The light detection module 102 is configured to emit a first light signal, detect a second light signal reflected by the first light signal, and send a detection result to the control module 101.

The control module 101 can determine whether the equipment is in a use state according to the detection result, and if the equipment is not in the use state, the carding equipment is controlled to stop running.

The carding device may be a device capable of providing a carding function, carding a carded object, and may include, for example, a hair care comb, a styling comb, and the like. The grooming object may be a user's hair or the like. In practical application, the equipment body of the carding equipment can comprise a carding part, the carding part can comprise a plurality of comb teeth, the comb teeth are contacted with a carding object to carry out carding, and the equipment body can also comprise a heating module, a temperature and humidity acquisition module and other carding modules which are matched with the carding part for use. Taking a hair care comb as an example, comb teeth are contacted with hair for combing, a heating module can heat the hair, and a temperature and humidity acquisition module can acquire the humidity of the hair and the like. In one or more of the following embodiments, the technical solutions of the embodiments of the present application will be described with reference to a comb device as a hair care comb.

A control module 101 is provided in the carding machine and can be used to control the machine to stop running when the machine is not in use. In practical application, the control module may be implemented as a microcontroller unit (MCU), a microprocessor, a single-chip microcomputer, etc.

In this embodiment, a light detection module 102 is further disposed in the carding device, where the light detection module 102 is connected to the control module 101, and operates under the control of the control module 101. The light detection module may in particular comprise a sensor assembly or the like for detecting whether the comb device is in use. The use state may be a state in which the carding device is in contact with a carding object to perform a carding operation. It is possible to determine whether the carding device is in use by detecting whether the carding device is in contact with a carding object by means of an optical signal. Specifically, the light detection module 102 may emit an optical signal and detect a reflected optical signal of the optical signal. For ease of description, the emitted light signal may be referred to as a first light signal and the reflected light signal may be referred to as a second light signal.

According to the light propagation rule, when the carding device is contacted with the carding object, the first light signal emitted by the light detection module is reflected by the carding object, and at the moment, the light detection module can detect the second light signal reflected by the first light signal. When the carding device is not in contact with the carding object, the first optical signal will not emit, and the optical detection module cannot detect the second optical signal. Therefore, according to the detection result of the light detection module, whether the carding device is in a use state can be determined.

The light detection module 102 may send the detection result to the control module 101, and the control module 101 determines whether the carding device is in use or not based on the detection result. If the equipment is not in the use state, the equipment can be controlled to stop running.

Alternatively, if it is determined that the device is in use, the device may be controlled to continue to operate.

In practical application, the device body further comprises a base adjacent to the carding portion. Taking a hair care comb as an example, the comb part may include a plurality of comb teeth extending outward from the base, and the comb teeth contact hair to comb. Wherein, be provided with in the base and hold the chamber, hold the chamber and be provided with transparent window on the one side base towards the broach. The light detection module can be fixed in the accommodating cavity, and emits and detects light signals through the transparent window on the base, so that whether the carding device is in a use state is determined. The transparent window can be realized as a transparent plastic piece, and has the functions of light guide and water resistance.

In the carding device provided in this embodiment, the device body includes a control module and a light detection module connected to the control module, where the light detection module may emit a first light signal and detect a second light signal reflected by the first light signal. According to the detection result of the light detection module, whether the equipment is in a use state or not can be judged, and when the equipment is not in the use state, the equipment is controlled to stop running, so that the automatic control of closing of the carding equipment is realized, and the potential safety hazard caused by that a user forgets to close the carding equipment is avoided.

In practical applications, the device body may further comprise a handle connected to the comb portion. Taking a hair care comb as an example, the handle can be positioned in a direction perpendicular to the plurality of comb teeth, and a user can hold the handle to make the comb teeth contact with hair for combing. Wherein the handle may comprise a wall and a switch module provided on the wall. The wall can be provided with the chamber of holding in, hold and be provided with transparent window on the relative wall of chamber towards switch module, this transparent window and switch module can be symmetrical about the central axis of handle, and the user of being convenient for holds switch module and transparent window simultaneously. The light detection module can be fixed in the accommodating cavity and emits and detects light signals through a transparent window on the wall. At this time, when the carding device is in the state of use, need the user to hold the handle, the user's hand contacts with the wall of handle, forms in transparent window department and shelters from, and the first light signal that light detection module transmitted will take place the reflection through the user's hand, and light detection module can detect the second light signal of first light signal reflection this moment. When the carding device is not in a use state, the user does not hold the handle, the first optical signal cannot be emitted, and the optical detection module cannot detect the second optical signal, so that whether the carding device is in the use state or not can be determined.

Optionally, the light detection modules may be fixed in the accommodating cavities provided in the walls of the base and the handle, so that the comb device is determined to be in a use state according to the detection results fed back by the two light detection modules. For example, when the two light detection modules detect the reflected light signals, the device is determined to be in a use state, and when any one light detection module cannot detect the reflected light signals or both light detection modules cannot detect the reflected light signals, the device is determined to be not in the use state, and the device is controlled to stop running, so that the detection accuracy is improved.

In practical applications, controlling the device to stop running may include different implementations. As an alternative implementation, the comb module of the device may be controlled to stop, e.g. the heating module may be controlled to stop heating or to pause heating, etc., at which point the device may be in a standby mode.

As another alternative implementation, stopping power to the device may be further included, so as to control the device to be powered off, and enable the device to be in a power-off mode. As shown in fig. 2, a schematic structural diagram of another embodiment of a carding device provided in the present application is different from the embodiment shown in fig. 1, and the carding device further includes a switch module 103 connected to the control module 101, and a power supply module 104 connected to the switch module 103.

Wherein, the power supply module 104 is used for providing working voltage to the equipment when the switch module 103 is closed;

the control module 101 is specifically configured to control the switch module 103 to be turned off and interrupt the operating voltage provided by the power supply module 104 if the device is not in a use state.

In this embodiment, a switch module 103 is also provided in the carding device for controlling the supply or stop of the operating voltage to the carding device. Specifically, when the switch module 103 is closed, the power module 104 provides an operating voltage to the grooming device and the device is in an operating mode. When the switch module 103 is turned off, the power supply module 104 cannot provide the working voltage to the carding device, the carding device cannot obtain the working voltage, and the device is in a shutdown mode.

The switch module 103 is connected to the control module 101 and can be turned on or off under the control of the control module 101. For example, if the switch module 103 is closed, the control module 101 may control the switch module 103 to be opened, so as to interrupt the working voltage provided by the power supply module 104, and switch the device to the shutdown mode.

Optionally, the switch module 103 may also be turned on or off based on user operation. For example, in response to a shutdown operation triggered by a user, the switch module 103 is turned off, and the operating voltage provided by the power supply module 104 is interrupted, so that the device is switched to the shutdown mode.

In practical use, when the carding machine is in the working mode, there are cases where it is not in contact with the carding object, but in contact with other objects. Taking the example of a comb device as a hair care comb, the hair care comb may be placed on a contact surface, such as a table top, a wall surface, etc., with which the teeth of the hair care comb will be in contact. At this time, the first optical signal emitted by the optical detection module still emits through the contact surface, and the optical detection module still receives the second optical signal reflected by the first optical signal, which causes interference to the judgment of whether the carding device is in the use state.

In order to improve the accuracy of the detection, in some embodiments, the control module may specifically determine, according to the detection result, whether the contact distance between the carding device and the contact object meets the carding condition. Wherein the combing condition may be a contact distance range with the combing object when the apparatus is in a use state. The contact distance range may be preset according to actual situations.

Taking the comb device as a hair care comb, the comb object is hair of a user, and when the comb teeth of the hair care comb are contacted with the hair, the contact distance between the comb teeth is usually smaller than the length of the comb teeth. While the teeth of the hair care comb are contacted with other objects, such as a tabletop, the contact distance between the teeth is usually equal to the length of the teeth. For example, the length of the comb teeth may be 2 centimeters (cm), the contact distance between the comb teeth and the hair may be 0 to 1.5cm, and the contact distance between the comb teeth and the table top may be 2cm. Therefore, the contact distance between the carding device and the contact object can be judged according to the detection result, and if the contact distance is judged to be in the preset contact distance range, the fact that the carding device is in contact with the carding object can be determined, and the carding device is in a use state. Otherwise, it may be determined that the comb device is not in use.

The specific manner in which the control module determines the contact distance between the carding device and the contact object based on the detection result will be described in the following embodiments, and will not be described herein.

In practical applications, in order to improve the user experience, it may not be necessary to immediately control the device to be turned off when it is determined that the card device is not in use. In some embodiments, the control module may control the device to stop running if it is determined that the device is not in a use state within a preset period of time according to the detection result.

If the carding equipment is not in a use state within the preset time period, the user is indicated that the carding equipment is not required to be carded, and the carding equipment can be closed. The preset time period may be set according to practical situations, for example, may be set to three minutes, five minutes, or the like, and is not particularly limited herein.

Optionally, if the carding device is not in a use state within a preset time period, it indicates that the user still has a carding requirement, and the carding device is not turned off at this time. And when the equipment is not in the use state, the control module controls the equipment to stop running again according to the detection result if the equipment is determined to be not in the use state within the preset time period.

In this embodiment, by setting the preset time period, the problem that the user needs to restart the carding device due to the fact that the user still has the carding requirement but the device is closed at intervals when the carding device is not used is avoided, and the use experience of the user is improved.

As shown in fig. 3, a schematic structural diagram of another embodiment of a carding device provided in the present application, where the light detection module may include a light emitting module 1021 and a light processing module 1022.

Wherein the light emitting module 1021 may be configured to emit a first light signal;

the optical processing module 1022 may be configured to detect the second optical signal reflected by the first optical signal, and send the detection result to the control module 101.

In this embodiment, the light detection module may include a light emission module and a light processing module. The light emitting module may include a light emitting sensor assembly for emitting a first light signal, and the light processing module may include a light processing sensor assembly for detecting a second light signal reflected by the first light signal and transmitting the detection result to the control module. To facilitate control module identification, the detection result may be sent to the control module in the form of an electrical signal, such as a voltage signal, a power signal, etc. For example, the light emitting sensor assembly may be implemented as a light emitting diode and the light processing sensor assembly may be implemented as a photodiode.

In practical application, the infrared light is not visible to human eyes, so that interference to a user is avoided in the use process, and the signal light for detection can be realized as infrared light. Correspondingly, the light-emitting sensor component can be realized as an infrared light-emitting sensor component, such as an infrared-emitting diode.

Wherein, light emission sensor subassembly and light processing sensor subassembly can the syntropy setting, specifically can be that light emission sensor subassembly and light processing sensor subassembly can all set up in carding equipment, towards the one side of carding the object, and the emitting end of light emission sensor subassembly and the receiving end of light processing sensor subassembly all are towards carding the object.

For ease of understanding, fig. 4-1 shows a top view of one embodiment of a light emitting module and a light processing module, and fig. 4-2 shows a side view of one embodiment of a light emitting module and a light processing module. Referring to fig. 4-1 and 4-2, taking an infrared emitting diode as an example of the light emitting module and a photodiode as an example of the light processing module, a light-tight partition board is disposed in the accommodating cavity, the partition board divides the accommodating cavity into a first area a and a second area B, an infrared emitting diode a is disposed in the first area a, and a photodiode B is disposed in the second area B. The height of the partition plate may be higher than the heights of the infrared emitting diode a and the photodiode b and lower than the height of the accommodating chamber.

Optionally, a first fixing member may be disposed in the first area a, a second fixing member may be disposed in the second area B, and the infrared emitting diode a and the photodiode B may be disposed on a circuit board, and the circuit board may be connected to the first fixing member and the second fixing member, so that the infrared emitting diode a is located in the first area a, and the photodiode B is located in the second area B.

In practical applications, considering that the first optical signal emitted by the optical emission module propagates in a straight line, and reflects after being carded by the object or the contact object, the optical processing module detects the second optical signal reflected by the first optical signal, and sends the detection result to the control module, which may also include different implementation manners.

Alternatively, if the optical processing module detects the second optical signal reflected by the first optical signal, the second optical signal may be converted into an electrical signal, and the electrical signal may be sent to the control module.

Optionally, if the optical processing module does not detect the second optical signal reflected by the first optical signal, a preset electrical signal may be sent to the control module.

The control module can be specifically used for judging whether the contact distance between the equipment and the contact object meets the carding condition according to the electric signal fed back by the light processing module, and if not, determining that the carding equipment is not in a use state.

Specifically, when the optical processing module does not detect the second optical signal reflected by the first optical signal, it indicates that the carding device is not in contact with the carding object or other objects, and at this time, a preset electrical signal may be sent to the control module. Taking the example that the electrical signal is a voltage signal, the preset electrical signal may be set to 0V for convenience of setting.

When the optical processing module detects the second optical signal, the carding device is in contact with the carding object or other objects, and the electric signal obtained by converting the second optical signal can be different from the preset electric signal. Taking the example that the electric signal is a voltage signal, the electric signal obtained by the conversion process may be greater than 0V. Alternatively, the light detection module may detect the second light signal within a preset time interval, where the preset time interval may be set according to the actual situation.

The control module can judge that the carding object is not in contact with the carding object and is not in a use state according to the electric signal value, if the electric signal value is 0V, can continuously judge whether the contact distance between the equipment and the contact object meets the carding condition according to the electric signal value if the electric signal value is more than 0V, and if the electric signal value is not more than 0V, the equipment is not in the use state, and the equipment is switched to a shutdown mode.

Optionally, the control module may be specifically configured to determine, according to the electrical signal fed back by the optical processing module, whether the electrical signal is in a preset electrical signal range; if not, determining that the equipment is not in a use state.

The preset electric signal range can be an electric signal numerical range fed back by the light processing module when the contact distance between the equipment and the contact object meets the carding condition.

The control module can judge that the carding device is in contact with the carding object and is in a use state according to the electric signal value, if the electric signal value is in a preset electric signal range, the carding device is not in contact with the carding object and is not in a use state, and the carding device is not closed if the electric signal value is not in the preset electric signal range. The preset electric signal range can be set according to actual conditions.

Through converting the detection result into an electric signal, the control module is convenient for identifying the detection result, and the detection result is clear and visual.

In practical application, the light detection module operates under the control of the control module, specifically, may respond to a detection instruction sent by the control module to perform detection. In some embodiments, the control module is further configured to send a detection instruction to the light emitting module;

The light emitting module is specifically configured to emit a first light signal based on the detection instruction.

There are also various implementations in which the control module sends the detection instruction. As an alternative implementation manner, the control module may send a detection instruction to the light emitting module when the detection device switches to the working mode.

As another alternative implementation manner, the control module may send a detection instruction to the light emitting module after detecting that the device is switched to the operation mode for a specific time. After a certain time when the device is switched to the working mode, the carding operation of the carding device can be finished, and whether the device is in a use state can be detected. The specific time may be set according to practical situations, for example, one minute, two minutes, and the like.

As yet another alternative implementation, the control module may detect a user shutdown instruction and send the detection instruction to the light emitting module. The user shutdown instruction may be generated by the switch module in response to a user-triggered shutdown operation. After the user triggers the shutdown operation, whether the equipment is in a use state can be confirmed, so that the problem that potential safety hazards exist because the equipment is still in the use state due to the shutdown operation error of the user is avoided.

As shown in fig. 5, a schematic structural view of a further embodiment of a carding device is provided. Wherein the light emitting module includes a signal receiving module 10211 connected with the control module 101, and a light emitter 10212 connected with the signal receiving module 10211; the light processing module includes a light detector 10221.

The signal receiving module 10211 may be configured to receive the detection instruction sent by the control module 101, and control the light emitter 10212 to start based on the detection instruction;

the optical transmitter 10212 is configured to transmit a first optical signal;

the photodetector 10221 is configured to detect the second optical signal reflected by the first optical signal, convert the second optical signal into an electrical signal, and send the electrical signal to the control module 101.

In this embodiment, the light emitters may be implemented as light emitting diodes. Taking the example that the optical signal is infrared light, the light emitter may be implemented as an infrared emitting diode, and the light detector may be implemented as a photodiode. The signal receiving module may be implemented as a control circuit, and the detection instruction may be implemented as a level signal.

Fig. 6 shows a circuit diagram of an embodiment of a signal receiving module, which may include a triode Q1, a MOS transistor Q2, a first variable resistor R1, a second variable resistor R6, a first resistor R2, a second resistor R3, a third resistor R4, a fourth resistor R5, a fifth resistor R7, and a sixth resistor R8.

The light emitting diode D2 and the photodiode D1 are disposed in the above circuit, and operate under the control of the circuit.

The base electrode of the triode Q1 is connected with the control module through a fourth resistor R5 and is used for responding to the level signal sent by the control module, the collector electrode is connected with the power supply voltage through a first resistor R2, and the emitter electrode is grounded.

One end of the second resistor R3 is connected with the power supply voltage through the first resistor R2, and the other end of the second resistor R3 is grounded through the sixth resistor R8.

The grid electrode of the MOS tube Q2 is connected with the power supply voltage through the second resistor R3 and the first resistor R2, the drain electrode is connected with the cathode of the light emitting diode D2, the source electrode is grounded, and the anode of the light emitting diode D2 is connected with the power supply voltage through the first variable resistor R1. The working voltage of the light emitting diode D2 can be changed by adjusting the first variable resistor R1, so that the intensity of the optical signal can be changed, and the setting can be performed according to actual conditions.

The cathode of the photodiode D1 is connected to the power supply voltage, and the anode is grounded through the second variable resistor R6. Meanwhile, the anode of the photodiode D1 is connected to the control module through a third resistor R4.

One end of the fifth resistor R7 is connected with the base electrode of the triode Q1, and the other end of the fifth resistor R is grounded.

The maximum resistance of the first variable resistor R1 and the second variable resistor R6 is 10kΩ (Ω), the resistance of the first resistor R2, the second resistor R3, the third resistor R4 and the fourth resistor R5 is 1kΩ, and the resistance of the fifth resistor R7 and the sixth resistor R8 is 10kΩ.

Specifically, when the control module sends a high-level signal, the triode Q1 is turned on, the power supply voltage is transmitted through the first resistor R2, the voltage between the second resistor R3 and the sixth resistor R8 is zero, that is, the voltage at the gate of the MOS transistor Q2 is zero, the MOS transistor Q2 is not turned on, the light emitting diode D2 cannot receive the power supply voltage, and the first optical signal is not emitted.

When the control module sends a low level, the triode Q1 is not conducted, the power supply voltage is transmitted through the first resistor R2, the second resistor R3 and the sixth resistor R8, the voltage between the second resistor R3 and the sixth resistor R8 is not zero, namely the voltage at the grid electrode of the MOS tube Q2 is not zero, the MOS tube Q2 is conducted, the light emitting diode D2 can receive the power supply voltage, and the first optical signal is emitted.

In this embodiment, by setting the signal receiving module connected to the control module and the light emitter, the light emitting module may emit the first light signal based on the level signal sent by the control module, so as to detect the first light signal, thereby realizing the control of the light emitting module by the control module.

As shown in fig. 6, the light processor is implemented as a photodiode D1. As is clear from the characteristics of the photodiode, the photodiode operates at a reverse voltage, and the reverse current is weak in an environment without illumination, and increases in an environment with illumination, and increases as the illumination intensity increases. The process of determining whether the carding device is in use or not by the control module based on the electric signal fed back by the light processing module will be described below with reference to the circuit diagram shown in fig. 5 and the operation characteristics of the photodiode.

The light emitting diode D2 emits a first light signal, if the carding device is not in contact with a carding object or other objects, the first light signal is not emitted, the photodiode D1 cannot detect a second light signal, no current exists between the photodiode D1 and the variable resistor R6 in a non-illumination environment, and a voltage signal fed back to the control module is 0V.

The light emitting diode D2 emits a first light signal, and if the carding device contacts with a carding object or other objects, the first light signal is reflected by the carding object, the photodiode D1 detects a second light signal reflected by the first light signal, the photodiode D1 has a certain resistance value under an illumination environment, and a current is provided between the photodiode D1 and the variable resistor R6. At this time, the voltage signal fed back to the control module has a certain value.

Further, the contact distance between the carding device and the carding object is in a preset distance range, for example, the contact distance can be 0-1.5 cm. When the contact distance is 0, the illumination intensity of the second optical signal detected by the photodiode D1 is larger, the resistance value of the photodiode D1 is smaller, the current between the photodiode D1 and the variable resistor R6 is larger, and the voltage signal fed back to the control module is larger. When the contact distance becomes larger, the illumination intensity of the second optical signal detected by the photodiode D1 decreases, the resistance value of the photodiode D1 increases, the current between the photodiode D1 and the variable resistor R6 decreases, and the voltage signal fed back to the control module decreases.

When the carding device is contacted with a carding object, the voltage signals fed back to the control module are all larger than the voltage signals fed back to the control module when the contact distance is 1.5 cm. Therefore, the voltage signal fed back to the control module when the contact distance is 1.5cm can be preset as the voltage signal threshold. Such as may be set to V0. In actual detection, the voltage signal fed back by the optical processing module can be compared with the voltage signal threshold. If the detected voltage signal is larger than the threshold value, the carding device is indicated to be in contact with the carding object and is in a use state, and if the detected voltage signal is smaller than or equal to the threshold value, the carding device is indicated to be not in contact with the carding object and is not in the use state.

In practical application, when the control module performs feedback according to the electric signal fed back by the optical processing module, taking the example that the electric signal is a voltage signal, usually, a voltmeter is used to read the value of the voltage signal, and compare the value with a voltage signal threshold. For ease of data reading and comparison, optionally, the voltage signal threshold may be set to be within a range of values in the voltmeter. Specifically, the voltage signal threshold can be controlled to be in the middle range of the voltmeter value by adjusting the variable resistor R6.

In practical application, the carding device can be further provided with a distance detection module for detecting the contact distance between the device body and the contact object when the device body is in contact with the contact object, and sending the distance detection result to the control module, so that the control module can determine whether the device is in a use state by combining the distance detection result and the detection result sent by the light detection module. The distance detection result may be directly implemented as a distance value. The distance detection module may be implemented as a distance measurement sensor or the like, for example.

As an alternative embodiment, taking a hair care comb as an example, the comb portion may include a plurality of comb teeth extending outwardly from the base, the comb teeth being contacted by hair for combing. The distance detection module can be arranged between the comb teeth, and detects the distance between the equipment and the contact object when the equipment contacts the contact object; the light detection module can be fixed in a containing cavity arranged in the base and emits and detects light signals through the transparent window. Thereby determining whether the carding device is in a use state based on the distance detected by the distance detection module and the light signal condition detected by the light detection module.

As another alternative embodiment, taking a hair care comb as an example, the comb part may include a plurality of comb teeth, and the distance detection module may be disposed between the comb teeth to detect a distance between the device and the contact object when the device contacts the contact object; the device body may further include a handle connected to the combing portion, and the light detection module may be fixed to a receiving cavity provided in a wall of the handle, and emits and detects light signals through the transparent window. Thereby determining whether the carding device is in a use state based on the distance detected by the distance detection module and the light signal condition detected by the light detection module.

The following describes a process in which the control module determines whether the carding apparatus is in a use state based on the distance detected by the distance detecting module and the light signal condition detected by the light detecting module.

The control module may be specifically configured to determine that the device is not in a use state if the second optical signal reflected by the first optical signal is not detected according to the detection result sent by the optical detection module, or the second optical signal is detected and the distance detection result of the distance detection module is greater than a preset distance.

Taking the comb device as an example, if the light detection module does not detect the second light signal according to the detection result sent by the light detection module, for example, the detection result sent by the light detection module may be a preset electrical signal, the preset electrical signal may be 0V, it may be determined that the device body is not in contact with any contact object, and at this time, it may be directly determined that the device is not in a use state.

If it is determined that the light detection module detects the second light signal according to the detection result, for example, the detection result sent by the light detection module may be any electric signal except a preset electric signal, for example, may be 1V, which indicates that the device body is in contact with hair or other objects. Further, if the distance between the device body and the contact object is determined to be greater than the preset distance according to the distance detection result, the preset distance may be, for example, the length of the comb teeth, and it may be determined that the device body is in contact with other objects, not hair, so as to determine that the device is not in a use state.

If the optical detection module detects the second optical signal according to the detection result, for example, the electrical signal value is not 0V, further, if the distance between the device body and the contact object is not greater than a preset distance according to the distance detection result, the preset distance may be, for example, the length of the comb teeth, and the device body and the hair may be determined, so that the device is determined to be in a use state.

Through the setting of distance detection module, can realize when the optical detection module judges that equipment body and contact object contact, directly acquire the distance numerical value between the two and judge, need not to convert the second optical signal that detects into the electrical signal, judge based on the electrical signal numerical value again to improve detection efficiency.

In order to improve the accuracy of detection, optionally, the control module may further determine that the device is not in a use state when the detection result of the distance detection module is greater than a preset distance, if the detection result sent by the light detection module determines that the second optical signal is detected, and the second optical signal is converted into an electrical signal, and the electrical signal is determined not to be in a use state. The device is judged not to be in a use state based on the electric signal converted from the detected reflected light signal, and the device is determined not to be in the use state based on the detection distance value when the device is judged not to be in the use state, so that the detection accuracy can be improved, and the condition that the device is not accurate enough in judgment based on a single electric signal or the distance value is avoided. The specific determination method is described in detail in the previous embodiments, and will not be described here again.

In practical application, the carding device can be further provided with a temperature acquisition module and a heating module. The temperature acquisition module can be used for detecting the humidity and the environmental temperature of the carding object when the equipment is in contact with the carding object, sending the detection result to the control module, adjusting the heating temperature of the heating module according to the detection result by the control module, and controlling the heating module to heat the carding object at the heating temperature. The temperature acquisition module can be implemented as a temperature and humidity sensor component and the like, the heating module can be implemented as a heat conduction comb tooth and the like, and specific implementation modes can refer to implementation modes in a traditional scheme, so that repeated description of the embodiment is omitted.

For specific implementation manners, reference may be made to implementation manners in the conventional schemes, and no detailed description will be given.
