[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] The core of this utility model is to provide a molding device.

[0040] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Figure 1 For structural diagrams of the molding equipment, such as Figure 1 As shown, the modeling device includes: a first thermistor 1, a modeling accessory 2, a main body 3, and a heating element 4. The connection relationship of the components within the modeling device is as follows: the modeling accessory 2 is connected to the main body 3, the modeling accessory 2 is provided with an air outlet 21, and the first thermistor 1 is located at the air outlet 21; the heating element 4 is located in the main body 3; the controller 31 in the main body 3 is electrically connected to the first thermistor 1 and the heating element 4 respectively.

[0042] In this embodiment, the operator heats the styling device (e.g., a curling iron) by adjusting the temperature button until the heating element 4 meets the required operating status (the heating power of the heating element 4 meets the requirements). This is indicated by an indicator light on the styling device (e.g., the indicator light remains constantly lit). However, during use, the styling accessory 2 comes into contact with the hair, and the hair becomes tangled around it. This causes the air outlet 21 on the styling accessory 2 to become blocked, resulting in an excessively high temperature on the styling accessory 2 at that moment. Since the heating element 4 does not detect this change, using the styling device under these conditions can damage the hair.

[0043] Therefore, the first thermistor 1 is arranged in the styling accessory 2, and is arranged at the air outlet 21 in the styling accessory 2 in particular, and is electrically connected with the controller 31 in the main body 3, which mainly functions to collect the temperature of the styling accessory 2 at the current time, that is, to collect the first temperature value, and then send the first temperature value to the controller 31 in the main body 3. At the same time, the controller 31 is also electrically connected with the heating component 2 to obtain the heating temperature value corresponding to the current heating power of the heating assembly 4. After the controller 31 in the main body 3 obtains the first temperature value and the heating temperature value, the working state of the heating assembly 4 is re-controlled and adjusted (for example, the heating power is increased or decreased), so as to realize the temperature compensation of the styling accessory 2, so as to ensure that the temperature at the air outlet 21 in the styling accessory 2 will not damage the hair quality.

[0044] The temperature compensation of the styling accessory 2 is specifically that when the first temperature value is greater than the heating temperature value, the heating assembly 4 is controlled to decrease the heating power, so as to decrease the temperature of the styling accessory 2. When the first temperature value is not greater than the heating temperature value, the heating assembly 4 is controlled to increase the heating power, so as to increase the temperature of the styling accessory 2.

[0045] When the controller in the main body 3 compensates the temperature of the styling accessory 2, the magnitude of increasing or decreasing the heating power can be determined according to the temperature difference between the first temperature value and the heating temperature value, so as to more accurately realize the temperature compensation of the styling accessory 2.

[0046] The first thermistor 1 is arranged at the air outlet 21, and is fixed at the fixed groove at the position of the air outlet 21 in the styling accessory, so as to avoid that the first thermistor 1 moves in the air outlet 21 or the styling accessory 2 along with the action of the operator during the use of the styling device. At the same time, the first thermistor 1 can select a negative temperature coefficient thermosensitive ceramic assembly, so as to further improve the accuracy of the temperature compensation. The first thermistor 1 can be electrically connected with the controller 31 in the main body 3 through a pin or a spring pin.

[0047] The utility model provides a kind of modeling equipment, it include: first thermistor, heating component, modeling accessory and main body;Wherein, modeling accessory is connected with main body, and air outlet is equipped on modeling accessory, and first thermistor is arranged at air outlet, for collecting the first temperature value of air outlet;Heating component is arranged in main body, for providing preset temperature value for modeling accessory;The controller in main body is electrically connected with first thermistor and heating component, for controlling the working state of heating component according to the first temperature value obtained.It can be seen from this that the first thermistor is arranged at air outlet, for collecting the first temperature value of modeling accessory itself more accurate, and first temperature value is sent to controller;And controller can determine temperature difference according to first temperature value and the heating temperature corresponding to heating component, to adjust its own heating component, realize temperature compensation to modeling accessory in modeling equipment, avoid modeling accessory temperature excessively high damage hair quality.

[0048] In the embodiment, the modeling equipment formed by the first thermistor 1, the air outlet 21, the modeling accessory 2, the main body 3 and the heating component 4 can only realize temperature compensation of the modeling accessory 2 with the temperature rising due to the hair winding the modeling accessory 2 and blocking the air outlet 21 during use, but in actual application, there is a certain error in determining the heating temperature according to the heating power of the heating component 4, and the temperature of the modeling accessory 2 is also affected by the use environment temperature of the modeling equipment. Figure 2 As shown in the above embodiment, in addition to the first thermistor 1, the air outlet 21, the modeling accessory 2, the main body 3, the heating component 4 and the controller 31, the modeling equipment also includes: the second thermistor 5 and the third thermistor 6.

[0049] In the embodiment, the second thermistor 5 is arranged in the main body 3 and electrically connected with the controller 31, which functions to collect the second temperature value corresponding to the heating component 4, and then send the second temperature value to the controller 31, so that the controller 31 in the main body 3 controls the working state of the heating component 4 according to the first temperature value and the second temperature value.

[0050] In the embodiment, the outer wall of the main body 3 is provided with an air inlet 32 (the air inlet is specifically arranged at the end of the main body 3 away from the modeling accessory 2), the third thermistor 6 is arranged in the main body 3, and the third thermistor 6 is electrically connected with the controller 31. The third thermistor 6 is used to collect a third temperature value of the air inlet 32, and then the third temperature value is sent to the controller 31, so that the controller 31 controls the working state of the heating assembly 4 according to the third temperature value. That is, the controller 31 in the main body 3 performs temperature compensation on the modeling accessory 2 according to the first temperature value, the second temperature value and the third temperature value, so as to ensure that the temperature of the modeling accessory 2 meets the current modeling requirement.

[0051] At this time, the temperature compensation on the modeling accessory 2 is that when the third temperature value is lower than the normal temperature value (for example, 25℃), and the second temperature value is greater than the heating first temperature value, the heating assembly 4 is controlled to increase the heating power, so as to increase the temperature of the modeling accessory 2.

[0052] When the controller 31 in the main body 3 performs temperature compensation on the modeling accessory 2, the first temperature difference between the third temperature value and the normal temperature value and the second temperature difference between the first temperature value and the second temperature value can be used to determine the amplitude of the specific heating power of the heating assembly which is increased or decreased, so that the temperature compensation on the modeling accessory 2 is more accurate.

[0053] The second thermistor 5 is arranged in the main body 3 and is specifically fixed at the first fixed groove in the main body 3, so as to avoid that the second thermistor 5 moves in the main body 3 along with the action of the operator in the process of using the modeling equipment. At the same time, the second thermistor 5 can select a negative temperature coefficient thermosensitive ceramic assembly, so as to further improve the accuracy of temperature compensation. The second thermistor 5 can be connected with the controller 31 in the main body 3 through a pin or a spring pin.

[0054] The third thermistor 6 is arranged in the main body 3 and is specifically fixed at the second fixed groove in the main body 3, so as to avoid that the third thermistor 6 moves in the main body 3 along with the action of the operator in the process of using the modeling equipment. At the same time, the third thermistor 6 can select a negative temperature coefficient thermosensitive ceramic assembly, so as to further improve the accuracy of temperature compensation. The third thermistor 6 can be connected with the controller 31 in the main body 3 through a pin or a spring pin.

[0055] It should be noted that the embodiment provided in the application is only one possible implementation, but is not limited to only this implementation. The user can set it by himself according to the needs.

[0056] The hair styling device provided by the application can realize temperature compensation of the styling device in the use process due to the temperature decrease of the styling accessory caused by the external temperature, thereby improving the temperature compensation capacity and expanding the use environment of the styling device.

[0057] On the basis of the above-mentioned embodiments, as shown in the hair styling device, Figure 3 Further comprises: a printed circuit board PCB;

[0058] The printed circuit board PCB is connected with the first thermistor 1 through the connecting line 7. In the specific spatial design, the printed circuit board PCB is arranged at the connection of the styling accessory 2 and the main body 3, and the connecting line is arranged on the internal support of the styling accessory. Such design can avoid blocking the air outlet 21 as much as possible. The first thermistor 1 is arranged on the internal support of the styling accessory 2, and the distance between the first thermistor 1 and the air outlet is a third preset distance (which can be understood as close to the air outlet 2). Moreover, the size of the first thermistor 1 is smaller than the size of the air outlet 21, so as to avoid blocking the air outlet by the first thermistor, thereby affecting the temperature of the air outlet.

[0059] The PCB board has high density, reliability, durability and maintainability, and therefore in the hair styling device as shown in the hair styling device, Figure 3 The signal transmission can be further ensured to be stable.

[0060] Meanwhile, it should be noted that the printed circuit board provided by the application can be a multi-layer PCB board, which can further improve the quality of signal transmission, reduce electromagnetic interference, reliability and thermal management.

[0061] At the same time, the first electric contact is arranged on the side of the PCB board facing the main body 3, and the second electric contact is arranged on the side of the main body 3 facing the PCB board. That is to say, the electrical connection between the first electric contact and the second electric contact constitutes the connection between the PCB board and the main body 3. The whole can transmit data or signals through the first electric contact and the second electric contact, and can identify the type of the resistance on the PCB board according to the transmitted data, and can also analyze the data to determine the working state of the PCB board or the device connected with the PCB board.

[0062] In addition, as shown in the hair styling device, Figure 4 The styling accessory and the main body are connected in a detachable manner, which is convenient for the maintenance of the operator. Among them, Figure 3 And Figure 4 22 in the above-mentioned embodiments is the internal structure of the styling accessory 2.

[0063] Based on the above embodiments, the main body 3 further includes: a control circuit; the input terminal of the control circuit is connected to the output terminal of the first thermistor 1; the output terminal IO of the control circuit is connected to the corresponding input terminal of the controller 31. The main function of the control circuit is to convert the acquired first temperature value into a voltage signal so that the controller 31 can determine the corresponding temperature based on the voltage signal.

[0064] Its like Figure 5 As shown, the control circuit includes: a first voltage divider resistor R1, a second voltage divider resistor R2, a Zener diode (TVS), a first filter capacitor C1, and a second filter capacitor C2. The circuit connections are as follows: the first terminal of the first voltage divider resistor R1 is connected to the first terminal of the second resistor R2, the negative terminal of the Zener diode (TVS), and the first terminal of the first filter capacitor C1, and together they serve as the input terminal of the control circuit, connected to the output terminal of the first thermistor 1; the second terminal of the first voltage divider resistor R1 is connected to the first terminal of the second filter capacitor C2, and together they serve as the output terminal (IO) of the control circuit, connected to the corresponding input terminal of the controller 31; the second terminal of the second voltage divider resistor R2 is connected to the 5V power supply terminal; the second terminal of the second filter capacitor C2 is connected to the second terminal of the first filter capacitor C1, the positive terminal of the Zener diode (TVS), and the ground terminal of the first thermistor 1, and is grounded.

[0065] In this embodiment, the first voltage divider resistor R1 and the second voltage divider resistor R2 in the control circuit form a series voltage divider network. When the temperature of the first thermistor 1 increases, its resistance decreases. At this time, the voltage detected at the output terminal IO of the control circuit increases, and the controller determines the temperature of the first thermistor 1 based on the voltage detected at IO. The Zener diode (TVS) in the control circuit prevents interference during signal transmission. The first filter capacitor C1 and the second filter capacitor C2 in the control circuit serve to filter the transmitted signal.

[0066] It should be noted that the embodiments provided in this application are only one possible implementation method, but are not limited to this only implementation method. Users can set their own implementation methods according to their needs.

[0067] Therefore, this application includes a first thermistor within the styling accessory to collect the first temperature value of the air outlet in the styling accessory and send the first temperature value to the controller; simultaneously, a second thermistor and a third thermistor are installed within the main body to collect the second temperature value of the heating element and the third temperature value of the air inlet, and send the second and third temperature values ​​to the controller. The controller controls the working state of the heating element based on the first, second, and third temperature values, thereby achieving temperature compensation for the styling accessory in the styling equipment and preventing the heating element from overheating and damaging the hair.
