[0021] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0023] In one embodiment of the present invention, a multifunctional mobile folding electric heating blanket, see Figure 1, including a moisture-proof base pad 1, an electric heating wire 2, a temperature sensor, a controller 4 and a moisture-proof covering pad 5. The moisture-proof base pad 1 is provided with a fixing sleeve for fixing the electric heating wire 2. The fixing sleeve includes multiple groups of positioning strip-shaped protrusions 3 and positioning buckles. The positioning strip-shaped protrusions 3 are made of flexible material and can be bent and folded; the electric heating wire 2 is wired along the positioning strip-shaped protrusions 3 and fixed to the moisture-proof base pad 1 through the positioning buckles. The four sides of the moisture-proof covering pad 5 are correspondingly connected to the moisture-proof base pad 1. The moisture-proof base pad 1 and the moisture-proof covering pad 5 are both made of flexible fabrics and can be easily folded. Among them, the outer layer of the moisture-proof covering pad 5 is a polyester fiber coating, and its inner layer is a PVC waterproof coating. The moisture-proof base pad 1 is an aluminum film moisture-proof pad, and its length ranges from 0.8 to 1.5 m, and its width ranges from 0.5 to 1.2 m. The length and width of the moisture-proof covering pad 5 are the same as those of the moisture-proof base pad 1. The heating wire 2 and the temperature sensor are located between the moisture-proof base pad 1 and the moisture-proof covering pad 5, and the moisture-proof base pad 1 and the moisture-proof covering pad 5 are filled with flame-retardant and heat-insulating materials; the heating wire 2 and the temperature sensor are both electrically connected to the controller 4, and the controller 4 is provided with an interface adapted to a mobile power supply, such as a commonly used type-c interface. The controller 4 supplies power to the heating wire 2 by connecting to the mobile power supply, and the mobile power supply is a power bank or a battery.

[0024] The controller 4 is provided with a power regulator and different temperature control buttons, each temperature control button corresponds to a preset temperature range, for example, three temperature control buttons are provided, namely, high temperature, medium temperature and low temperature. The preset temperature range controlled by the high temperature temperature control button is (35, 40]°C, the preset temperature range controlled by the medium temperature temperature control button is (30, 35]°C, and the preset temperature range controlled by the medium temperature temperature control button is (25, 30]°C. If the temperature detected by the temperature sensor is lower than the corresponding preset temperature range, the controller 4 increases the output power through the power regulator; if the temperature detected by the temperature sensor is higher than the corresponding preset temperature range, the controller 4 reduces the output power through the power regulator; if the temperature detected by the temperature sensor is within the corresponding preset temperature range, the controller 4 maintains the current output power; when the controller 4 just starts to output to the electric heating wire 2, it first outputs at the maximum output power, and then adjusts the output power after reaching the corresponding preset temperature range, so as to ensure that the electric blanket can heat up at the fastest speed.

[0025] In one embodiment of the present invention, the heating wire 2 is evenly laid and fixed on the moisture-proof base pad 1 in a serpentine winding wiring manner, and the positioning buckle can be set as a buckle compatible with the heating wire 2, or can be set as a fireproof buckle for the heating wire 2 to pass through, and its form includes but is not limited to the above. The wiring interval of the heating wire 2 is kept at least 6cm, and the heating wire 2 does not cross wiring, so as to reduce the risk of short circuit of the heating wire 2.

[0026] In one embodiment of the present invention, the controller 4 is arranged outside the moisture-proof base pad 1 and the moisture-proof cover pad 5, and can also be arranged on the side of the electric blanket for easy control and maintenance. The controller 4 is provided with a power indicator light and a voltage stabilizer. If the mobile power supply is connected to the controller 4 and supplies power, the power indicator light is on, otherwise the power indicator light is off. The voltage stabilizer is used to stabilize the connected mobile power supply. For example, if the mobile power supply is a 36V battery, the voltage stabilizer is required to stabilize the voltage of the mobile power supply.

[0027] The controller 4 is also provided with a timer and a corresponding timing button, and the timer is used to time and shut down the heating. For example, the timing button is divided into half an hour, 1 hour, and 2 hours timing buttons; when the 1 hour timing button is pressed, the controller 4 automatically shuts down after 1 hour.

[0028] In one embodiment of the present invention, the multifunctional mobile folding electric blanket further includes a buzzer, which is electrically connected to the controller 4. If the temperature detected by the temperature sensor exceeds the safe temperature value, the controller 4 controls the buzzer to sound an alarm. For example, the safe temperature value is 45°C. When the temperature detected by the temperature sensor exceeds 45°C, it indicates that there is a risk of short circuit of the electric heating wire 2 or a risk of power output failure of the controller 4. When the user hears the alarm, he should turn off the electric blanket in time.

[0029] In one embodiment of the present invention, the multifunctional mobile folding electric heating blanket also includes multiple support rods, the moisture-proof base pad 1 is provided with a support sleeve adapted to the support rods on its plane, the support rods are inserted into the support sleeve to form an electric heating plate, and the moisture-proof base pad 1 is provided with a cloth sleeve adapted to the mobile power supply on one side edge, and the mobile power supply is inserted into the cloth sleeve to form the base of the electric heating plate.

[0030] Specifically, the support rod includes a horizontal rod and a vertical rod, and correspondingly, the support sleeve also includes a horizontal and vertical support sleeve. The horizontal rod and the vertical rod are respectively inserted into the corresponding support sleeves, and the original soft electric blanket is supported by the form of propping up the kite to form an electric heating plate, and then a mobile power supply is inserted into the base formed by the cloth sleeve. Since the mobile power supply is larger than the electric blanket, the electric heating plate can be erected, thus forming a foot drying board. The soft electric blanket was originally spread on the legs and feet for heating. Due to its poor air permeability, long-term heat accumulation is easy to cause burns. It is suitable for short-term rapid heating, but not suitable for long-term bedding. The electric blanket is propped up to form a heat source for heat dissipation. Although the heat loss is large, the heat received by the human body is more uniform, not easy to cause burns, and suitable for long-term heating.

[0031] The multifunctional mobile foldable electric blanket provided by the present invention utilizes a mobile power source to free itself from the constraints of a fixed socket, so that it can be used anytime, anywhere. In addition, the electric blanket is small in size and made of a thin and soft material, so it is convenient to carry and use at any time and fold and store, and is particularly suitable for outdoor use. The electric blanket has a precise temperature control function through temperature feedback, and heats up quickly at the start, so that the needs of users can be quickly met.

[0032] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope thereof. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
