Embodiment 1

[0049] A heating and temperature-sensitive knee pad, as shown in Figure 1, includes a knee pad body 1, an embedded function bag 2 and a controller 3, the knee pad body 1 includes an inner layer, an outer layer, and two adhesive tapes 4, one of which is The adhesive tape 4 is located at the left end of the outer layer of the knee pad body 1, and the other adhesive tape 4 is located at the right end of the inner layer of the knee pad body 1. The two adhesive tapes 4 can be pasted and fixed to each other, so that the The knee pad body 1 is fixed on the knee and fitted to the knee, and the knee pad body 1 is made of antibacterial and unidirectional moisture-wicking elastic fabric.

[0050] The heating device 15 is a flexible heating element prepared based on carbonized fabric, and the flexible heating element is composed of a substrate 25, a heating temperature-sensitive layer 26 and a covering fabric 21 arranged sequentially from bottom to top. Layer 26 includes a secondary treat...

Embodiment 2

[0060] A kind of working method based on the heating thermosensitive knee pad of embodiment 1, such as Figure 4 As shown, when it is necessary to adjust the temperature, the user controls and adjusts the heating adjustment switch 8 to make the heating module 15 reach the required temperature, and the corresponding program in the microprocessor 20 processes the received command to control the heating module 15. The power supply module 6 supplies power to the heating device 15, and the heating device 15 heats. The temperature sensor 16 monitors the surface temperature of the fabric in real time and displays it on the display 7. The outer layer is provided with a thermochromic region 12 to assist people in observing Knee temperature.

[0061] When the required humidity is not reached, the microprocessor 20 controls the heating adjustment switch 8 to make it in a saturated state, and the power module 6 continues to output power; if the set temperature is reached, the microprocess...

Embodiment 3

[0066] The flexible heating element of embodiment 1, such as Figure 6-7 As shown, the flexible heating element is prepared by the method of this embodiment, specifically:

[0067] Step 1, pretreating the fabric to be carbonized, and then subjecting the pretreated fabric to be carbonized to high-temperature carbonization treatment to obtain a carbonized fabric, the carbonized fabric is the conductive heating material of the heating temperature-sensing layer, and is a planar heating element . The constituent materials of the fabric are natural fiber fabrics, regenerated cellulose fiber fabrics or acrylic fabrics, the tissue structure of the fabrics is woven fabrics, knitted fabrics or non-woven fabrics, and the natural fiber fabrics are preferably cotton fabrics.

[0068] Step 2, coating or vacuum soaking the carbonized fabric with a polymer or a polymer solution, and then drying it to obtain a polymer / carbonized fabric;

[0069] Step 3, using a laser to scan the polymer / carb...

Abstract

The invention discloses a heating temperature sensing kneecap which comprises a kneecap body, an embedded functional bag and a controller, the embedded functional bag is detachably assembled on the kneecap body, and the embedded functional bag comprises a heating device electrically connected with the controller; the heating device is a flexible heating element, and the flexible heating element is formed by compounding a substrate, a heating temperature sensing layer and a covering fabric which are sequentially arranged from bottom to top. The heating temperature sensing layer comprises a secondary treatment carbonized fabric, a temperature sensor arranged on the surface of the secondary treatment carbonized fabric in an insulating manner, and two electrodes electrically connected with the secondary treatment carbonized fabric. The flexible heating element is adopted to achieve heating, stability is high, damage is not prone to occurring, the probability of potential safety hazards is reduced, the device can be well attached to the human body, and meanwhile the health indexes of the knees of the human body at the moment can be visually and clearly known through the humidity sensor and the temperature sensor.

Description

technical field [0001] The invention relates to the technical field of functional fabrics, in particular to a heating and temperature-sensitive knee pad. Background technique [0002] Traditional knee pads generally increase the thickness of the knee pads to keep warm or increase the support structure to relieve the load-bearing pressure on the knees. The various functions are independent of each other and the effect is single, which cannot meet many health needs of people. Some warm knee pads can play common multifunctional effects, but the knee pads themselves cannot generate heat, and when working in a cold environment for a long time, they cannot achieve the desired multifunctional effect of people. [0003] With the development of science and technology and the improvement of people's awareness of environmental protection and health preservation, people's personalized demand for knee pads is also increasing. At present, there are many knee pads on the market. The commo...
