BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a heated garment, and more particularly to a multi-function heated garment capable of performing multidirectional physical therapy.

2. Description of the Prior Art

In winter, the thermal performance of ordinary cotton-padded clothing and down jackets cannot fully meet human needs. The coats sold in the market have different thicknesses. In order to keep warm, people often choose thicker and heavier coats. The thermal performance of this jacket is not good, and the appearance of this jacket is unaesthetic. The heavy pressure also makes the wearer feel uncomfortable. Especially for outdoor workers, the heavier the clothing, the more it affects their actions and reduces work efficiency.

For this problem, heated clothing is developed accordingly. However, the conventional heated clothing has a relatively simple structure and function, and cannot perform multi-directional heating and infrared physical therapy on various parts of the human body. At present, it is difficult for a controller of the heated clothing on the market to quickly identify a quick charge source in order to charge a heating load more quickly (with a higher DC voltage), and thus resulting in long heating time and low heating efficiency. In addition, the conventional quick charge source will be in a sleep mode and result in no output current after having been working for a period of time. Therefore, it is necessary to study a solution to solve the above problems.

SUMMARY OF THE INVENTION

In view of the shortcomings of the prior art, the primary object of the present invention is to provide a multi-function heated garment capable of performing multidirectional physical therapy. It can effectively solve the problem that the conventional heated garment has a single structure and function, and the controller used is difficult to quickly identify the quick charge source, and it is difficult to charge the heating load quickly.

A multi-function heated garment comprises a garment body, a hood, a heating control device, a quick charge source, and a heating load. A top of the garment body is provided with first electrically conductive buttons. A bottom of the hood is detachably connected to the top of the garment body through a zipper. The bottom of the hood is provided with second electrically conductive buttons. The second electrically conductive buttons are buckled and electrically connected to the first electrically conductive buttons. The heating control device and the quick charge source are arranged in the garment body. The quick charge source and the first electrically conductive buttons are electrically connected to the heating control device. The heating load includes at least one first carbon fiber heating sheet and a second carbon fiber heating sheet. The first carbon fiber heating sheet is arranged inside the garment body and electrically connected to the heating control device. The second carbon fiber heating sheet is arranged inside the hood and electrically connected to the second electrically conductive buttons.

Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be known from the above technical solutions:

Since the Type-C interface34is plugged in the power bank and situated at a standby mode for a long time, the power bank will be in a sleep mode without outputting power.

Wherein, a transient voltage suppressor (TVS) diode is a general high-efficiency circuit protection device with an extreme quick response time (sub-nanoscale) and a very high surge absorption capacity. When both terminals of the TVS diode undergo an instant impact of high energy, the TVS diode can change the impedance between the two terminals from high impedance to low impedance and absorb a large instantaneous current and clamp the voltage at both terminals to a predetermined value to protect the subsequent circuits and components from being impacted by the transient high-voltage peak pulse power.

In this embodiment, the overvoltage detection circuit38is disposed between the button wake-up circuit31and the power supply circuit33.

Next, the principle of identifying the quick charge source40and charging the heated garment quickly will be elaborated below:

After the Type-C interface34is plugged and connected to the quick charge source40, the quick charge source40outputs a standard 5 VDC voltage, and the power supply circuit33converts the standard 5 VDC voltage into a 3.3V working voltage which is supplied to the main control chip U1and the status indicating light circuit37. After the main control chip U1is electrically conducted, the main control pin14and the main control pin15send a handshake signal to the corresponding pin D− and pin D+ of the Type-C interface34. Once the handshake communication succeeds, the pin OUT1− of the Type-C interface34outputs a 20V voltage to the drain of the MOS tube Q1. In the meantime, the pin OUT2− also outputs a 20V voltage to the drain of the MOS tube Q2, so that both MOS tube Q1and MOS tube Q2are electrically conducted, and the Type-C interface34outputs a 20V voltage to the corresponding heating load50for a quick charge and the heating load50can be heated quickly.

When this product is in use, the hood20can be connected or disconnected as required. When the hood20is connected, the second electrically conductive buttons63are buckled and electrically connected to the first electrically conductive buttons61. When the user puts on the heated garment, by controlling the heating control device30, the quick charge source40supplies power to the first carbon fiber heating sheet51, the second carbon fiber heating sheet52and the two third carbon fiber heating sheets53of the heating load50, so that the first carbon fiber heating sheet51, the second carbon fiber heating sheet52and the two third carbon fiber heating sheets53generate heat. The first carbon fiber heating sheet51generates heat to warm the user's cervical spine, back, waist, abdomen and son on and to perform infrared physical therapy. The second carbon fiber heating sheet52generates heat to warm the user's head and to perform infrared physical therapy. The two third carbon fiber heating sheets53generate heat to warm the user's ears and to perform infrared physical therapy. Thus, this product can perform multidirectional heating and infrared physical therapy on the human body.
