[0035] The utility model provides an intelligent temperature-controlled shawl, such as Figure 1-2 As shown, it at least includes a shawl body 1, a heating component 2 and a temperature sensing element. The shawl body is in a long strip shape; the heating component includes a plurality of heating sheets 21 arranged in the shawl body and a controller 22 connected to the heating sheets, the controller is fixedly arranged on the shawl body and is provided with a power interface 221; the temperature sensing element is electrically connected to the controller, and includes a first temperature sensing element for collecting ambient temperature and a second temperature sensing element for measuring the temperature of the heating sheets;

[0036] The controller is configured with a switch control circuit and a gear adjustment circuit, which are used to set the heating temperature according to the ambient temperature collected by the first temperature sensor element, adjust the gear of the heating plate according to the set heating temperature, and control the power on and off of the heating plate according to the temperature of the heating plate collected by the second temperature sensor element.

[0037] It should be noted that the controller sets the heating temperature according to the ambient temperature collected by the first temperature sensor element, and adjusts the gear position of the heating plate according to the set heating temperature, both of which can be realized by using circuits.

[0038] With this design, the shawl has a simple and light structure, good warmth retention effect, and can control the power supply to the heating plate according to the ambient temperature, and automatically adjust the working gear of the heating plate according to the temperature inside the heating plate. A comfortable temperature can be maintained without the user frequently adjusting the gear. It is simple, convenient and quick to use.

[0039] Preferably, the heating temperature is 40°-65°.

[0040] like Figure 3 As shown, the shawl body 1 includes at least a first fabric layer 11, a second fabric layer 12 and a heating layer 13 located between the first fabric layer and the second fabric layer. The heating sheets 21 are evenly spaced and fixed on the heating layer so that the heating layer generates heat evenly and maintains the overall temperature stability of the shawl body.

[0041] Preferably, the material of the heating layer includes non-woven fabric.

[0042] The controller is provided with a control switch 222 . The controller 22 is fixedly mounted on the second fabric layer 12 , and the control switch is located outside the second fabric layer 12 .

[0043] The power interface is connected to the controller via a wire 223 , and the second fabric layer 12 is provided with a through hole 121 , through which the wire passes, and the power interface is located on the outside of the second fabric layer.

[0044] The intelligent temperature-controlled shawl of this embodiment also includes a power supply 3, which is a mobile power supply, and the mobile power supply is detachably connected to the power interface 221. The power interface adopts a USB interface design, which, on the one hand, enables the intelligent temperature-controlled shawl to be used outdoors, which is more convenient, and the power bank can be replaced at any time, thereby improving the endurance of the heating function of the intelligent temperature-controlled shawl and continuously providing heat. On the other hand, it can be connected to a computer or other equipment through a USB interface, which is convenient for users to use indoors, thereby increasing the versatility of the intelligent temperature-controlled shawl.

[0045] A pocket 122 for placing a mobile power source is provided on the outer side of the second fabric layer near the power interface.

[0046] Preferably, Figure 1 As shown, the shawl body 1 is in the shape of an elongated strip, and a decorative tassel 123 is provided at the short side of the elongated strip.

[0047] The heating sheet 21 includes a plurality of cloth sheets on which heating wires 211 are arranged.

[0048] Preferably, the heating wire is a single-core heating wire, and the second temperature sensing element is a temperature sensing element fixed on the heating wire, which performs real-time temperature detection on the heating wire, stops heating when the temperature reaches the heating temperature, and starts heating when the temperature is lower than the heating temperature.

[0049] Preferably, Figure 4 As shown, the heating wire is a double-core PTC heating wire, which includes an outer sheath 2111, a winding core 2112, and an intermediate layer 2113 located between the outer sheath and the winding core. A heating wire 2114 is wound on the winding core. The second temperature sensing element is a detection wire 2115 wound on the intermediate layer, which can sense the temperature of the heating wire 2114 in real time, thereby collecting the temperature inside the shawl body. The material of the detection wire is pure nickel, and the temperature coefficient is 0.00455±0.0002.

[0050] Preferably, the first temperature sensing element is a thermistor, and as the temperature increases or decreases, the resistance value regularly decreases or increases. This is the prior art and will not be described in detail here.

[0051] like Figure 5 As shown, the control principle of the controller in this embodiment is:

[0052] Controlling the first temperature sensing element to collect the ambient temperature;

[0053] Control the second temperature sensing element to collect the temperature of the heating plate;

[0054] Set the heating temperature based on the collected ambient temperature;

[0055] Based on the set heating temperature, the gear adjustment circuit adjusts the gear of the heating sheet;

[0056] Based on the collected temperature of the heating plate, the power supply is controlled by the switch control circuit to supply power to the heating plate. If the temperature of the heating plate is lower than the set heating temperature, the control power supply is in working state and supplies power to the heating plate. Otherwise, the control power supply stops supplying power to the heating plate.

[0057] In order to explain the control principle more clearly, for example, when it is just turned on, the first temperature sensor element is controlled to collect the ambient temperature of 0 degrees, and correspondingly, the heating temperature is set to 50 degrees. Since the difference between the current ambient temperature and the set heating temperature is large, the heating plate is adjusted to a high power gear through the gear adjustment circuit. The second temperature sensor element is controlled to collect the temperature of the heating plate. When the temperature of the heating plate is close to the set heating temperature of 50 degrees, the heating plate is adjusted to a low power gear through the gear adjustment circuit to ensure its constant temperature. The user wears the smart temperature control shawl and enters an environment with an ambient temperature of 10 degrees again. Based on the ambient temperature collected by the first temperature sensor element, the corresponding heating temperature is set to 40 degrees. At the same time, the second temperature sensor element detects that the temperature of the heating plate is 50 degrees. At this time, the temperature of the heating plate is higher than the set heating temperature, and the switch control circuit controls the power supply to stop supplying power to the heating plate.

[0058] It should be noted that the above-mentioned heating temperature and power gear settings can be burned into the controller in the form of firmware when the product leaves the factory, and the controller is controlled based on the firmware configuration process, so no improvement of software and methods is involved.

[0059] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
