Description

Technical Field

[0001] The utility model relates to the technical field of cold-proof clothing, in particular to a novel electric heating cold-proof clothing. Background Art

[0002] Cold-proof clothing is clothing that people wear to keep warm in cold seasons. In order to provide cold-proof and warm insulation, some cold-proof clothing will be equipped with some electric heating mechanisms to increase the temperature and improve the warming effect. However, although most electric heating cold-proof clothing can be heated, no temperature adjustment mechanism is set. The internal temperature of the cold-proof clothing body remains unchanged. If the temperature is too low, the warming effect is poor. If the temperature is too high, it is easy to cause a lot of sweat and burns on the back of the person. For example, a Chinese utility model patent for solar electric heating clothing (application number 202021778391.7) uses solar panels to power the electric heating membrane to heat up the inside of the clothing. By opening the zipper 140 for ventilation, the excess heat is discharged from the clothing body 110. Although the heat can be reduced, a large amount of heat loss and electricity consumption are caused. For this reason, we propose a new type of electric heating cold-proof clothing to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide a new type of electric heating cold-proof clothing to achieve the above-mentioned purpose in view of the shortcomings of the prior art.

[0004] The utility model provides the following technical solutions: a novel electric heating cold-proof clothing, comprising a cold-proof clothing body, a cap sewn on the upper end of the cold-proof clothing body, a pocket connected to the lower surface, two shoulders and solar panels arranged below the chest, a heat preservation layer sewn on the inner surface of the back of the cold-proof clothing body, an electric heating film attached to the outer surface of the heat preservation layer by Velcro, a sliding variable resistance mechanism for adjusting temperature attached to the outer surface of the cold-proof clothing body, a first wire electrically connected between the sliding variable resistance mechanism and the solar panel, and a second wire connected between the electric heating film and the sliding variable resistance mechanism.

[0005] Compared with the prior art, the beneficial effects of the utility model are:

[0006] The sliding variable resistance mechanism of the present invention can not only act as a switch to open the electric heating diaphragm, but also adjust the heating power of the electric heating diaphragm, so as to adjust the internal temperature of the cold-proof clothing body, and select the appropriate temperature to reduce the cold. That is, by rotating the passage block clockwise or counterclockwise to change the length of the current passing through the resistor, the resistance value is adjusted, and the heating power of the electric heating diaphragm is adjusted, so as to achieve the effect of adjusting the internal temperature of the cold-proof clothing body and avoid power loss. The appropriate temperature can not only keep out the cold, but also prevent the wearer from sweating a lot on the back due to excessive temperature. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-5The utility model provides a technical solution: a new type of electric heating cold-proof clothing, including a cold-proof clothing body 1, a hood 3 sewn on the upper end of the cold-proof clothing body 1, a pocket 5 connected to the lower surface, and solar panels 2 arranged on both shoulders and under the chest. The solar panels 2 are made of flexible materials and can be attached to the outer surface of the cold-proof clothing body 1 to absorb sunlight and convert it into electrical energy. A heat-insulating layer 10 is sewn on the inner surface of the back of the cold-proof clothing body 1. An electric heating film 9 (which is a prior art, and the model and specific structure are not described here) is attached to the outer surface of the heat-insulating layer 10 through Velcro. The outer surface of the cold-proof clothing body 1 is attached with a heat-insulating film 9 for adjusting A sliding variable resistance mechanism 4 for adjusting the temperature, a wire 1 8 is electrically connected between the sliding variable resistance mechanism 4 and the solar cell panel 2, a wire 2 11 is connected between the electric heating diaphragm 9 and the sliding variable resistance mechanism 4, the current generated by the electric energy converted from sunlight flows into the sliding variable resistance mechanism 4 through the wire 1 8, and then flows into the electric heating diaphragm 9 through the wire 2 11, and finally returns to the solar cell panel 2, forming a closed circuit, so that the electric heating diaphragm 9 is energized to convert the electric energy into thermal energy, so that the inside of the new cold-proof clothing body 1 generates heat and generates temperature, and the heating power of the electric heating diaphragm 9 is adjusted by adjusting the resistance of the sliding variable resistance mechanism 4, so as to adjust the internal temperature of the cold-proof clothing body 1.

[0015] In this embodiment, specifically, how to adjust the resistance value of the sliding variable resistance mechanism 4 is introduced: the sliding variable resistance mechanism 4 includes an outer frame 41 of a circular structure, the outer frame 41 is fixed to the outer surface of the cold-proof clothing body 1, the outer frame 41 is rotatably connected to a rotating button 42, a copper ring 44 is fixed to the outer surface of the rotating button 42, a copper block 45 is fixed to the upper end of the copper ring 44, a resistor 43 is fixed to the inner surface of the outer frame 41, the upper end of the copper block 45 is in close contact with the inner surface of the resistor 43, the end of the wire 1 8 is electrically connected to the resistor 43, a brush 46 is fixed to the inner surface of the lower end of the outer frame 41, the lower end of the copper ring 44 is in close contact with the brush 46, and the brush 46 is electrically connected to the end of the wire 2 11;

[0016] By adopting the above technical solution, the wearer rotates the rotating button 42 clockwise to drive the copper ring 44 and the copper block 45 to rotate clockwise inside the outer frame 41 until the upper end of the copper block 45 contacts the lower surface of the resistor 43, that is, the copper block 45 reaches the position of point B ( Figure 3 As shown), at this time, the current flows from the solar cell panel 2 into the wire 1 8, then into the upper end of the resistor 43, then into the copper block 45, and then into the copper ring 44, and then the current passes through the brush 46 and the wire 2 11 and flows into the electric heating film 9. At this time, continue to rotate the knob 42 clockwise to rotate the copper block 45 clockwise from point B to point C, increase the length of the current moving on the resistor 43, increase the resistance value, thereby changing the resistance size, adjusting the current size, and changing the heating power of the electric heating film 9.

[0017] Furthermore, the wearer rotates the knob 42 counterclockwise to move the copper block 45 from point C to point B, thereby reducing the resistance value. When the copper block 45 rotates counterclockwise to disengage from the resistor 43 and reaches point A (neutral zone 12), the circuit is disconnected, and the electric heating diaphragm 9 is no longer powered, and heating stops. The sliding variable resistance mechanism 4 acts as a switch for the electric heating diaphragm 9 and adjusts the resistance of the electric heating diaphragm 9.

[0018] In order to adjust the resistance by rotating the copper ring 44 , the cross section of the copper ring 44 is in a C-shaped structure.

[0019] One end of the rotating button 42 extends out of the outer frame 41, and the outer frame 41 is arranged inside the pocket 5, that is, the sliding resistance mechanism 4 is arranged inside the pocket 5 and hidden, which does not affect the overall appearance of the cold-proof clothing body 1 and can protect the sliding resistance mechanism 4.

[0020] A retaining edge 7 is provided at the closed position on the front of the winter-proof clothing body 1 , and the retaining edge 7 is connected to the winter-proof clothing body 1 through buttons 6 for fastening the front of the winter-proof clothing body 1 .

[0021] It should be noted that the wire 1 8 is connected to the solar panel 2 through a detachable terminal, and the wire 2 11 is also connected to the electric heating diaphragm 9 through a detachable terminal, so that the electric heating diaphragm 9 is separated from the wire 2 11, and the electric heating diaphragm 9 can be removed by tearing off the electric heating diaphragm 9. In extreme environments, remove the wire 1 8 and connect it to the positive pole of the external mobile power supply, connect the electric heating diaphragm 9 to the negative pole of the mobile power supply, power the electric heating diaphragm 9, and generate heat and protect the cold-proof clothing body 1.

[0022] Working principle: the user puts on the cold-proof clothing body 1 to keep warm. In cold seasons, the solar panel 2 converts sunlight into electrical energy to power the electric heating film 9, and converts electrical energy into thermal energy to increase the temperature inside the cold-proof clothing body 1, which is more cold-proof. During the heating process of the electric heating film 9, the user can rotate the knob 42 to rotate the copper ring 44 and the copper block 45 inside the outer frame 41. During the process of the copper block 45 reaching the point C from the point B position, the length of the current passing through the resistor 43 is increased, thereby increasing the resistance value, reducing the current size, and reducing the heating power of the electric heating film 9. On the contrary, when the copper block 45 reaches the point B from the point C position, the resistance is reduced and the heating power of the electric heating film 9 is increased. In this way, the temperature rise of the electric heating film 9 is adjusted, and the internal temperature of the cold-proof clothing body 1 is adjusted to provide the user with a suitable temperature for keeping warm according to needs.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
