[0034] Example 1

[0035] Please refer to Figure 1 The present embodiment provides an electric heating shoe, comprising a boot body; a heater for heating the foot is provided inside the boot body; the boot body comprises a sole 2, the sole 2 is provided with a power supply component and a cooling device for cooling the power supply component; the heater is electrically connected to the power supply component; the sole 2 is also provided with a buffer device for protecting the cooling device.

[0036] In this embodiment, when people put on the hot shoes, they can connect the power supply assembly and the heater, and the heater starts to heat up. The heat of the heater is finally transferred to the feet to ensure that the feet will not be frostbitten. When the hot shoes are not in use, the power supply assembly and the heater can be disconnected to avoid high power consumption of the power supply assembly. When walking in the hot shoes, the cooling device has a cooling effect on the power supply assembly to ensure that the power supply assembly itself will not overheat due to long-term work. The outer wall of the cooling device is made of metal material, and the cooling device is in direct contact with the power supply assembly. The metal material has good thermal conductivity and relatively high strength. The cooling device has a certain protective and supporting effect on the power supply assembly. When the weight of the human body is transferred to the hot shoes, the gravity is transferred to the sole 2 of the boot through the cooling device and then to the ground.

[0037] If the power supply assembly is directly arranged inside the sole 2 of the boot, and no strong protective device is arranged around the power supply assembly, although the sole 2 of the boot may be made of plastic, which has a certain elasticity, the sole 2 of the boot will directly apply pressure to the power supply assembly when the foot presses the sole 2 for a long time, and the sole 2 of the boot will easily damage the power supply assembly.

[0038] In this embodiment, if Figure 2As shown, the buffer device is located on the rear side of the boot sole 2, and the buffer device includes a second air cushion 3 and a third air cushion 4; the second air cushion 3 is located above the cooling device, and the third air cushion 4 is located below the cooling device; a first air cushion 5 is provided on the front side of the boot sole 2; the boot sole 2 is also provided with an insole, and the first air cushion 5 and the second air cushion 3 are both located below the insole.

[0039] In detail, if the insole is placed directly on the sole 2, the insole material can be cotton breathable material, and the insole body is relatively soft. When the foot steps on the insole and walks for a short time, the foot will not be bruised or sore. However, the cooling device is made of metal material. Although the cooling device is located inside the sole 2, the foot can still feel the hard texture of the back side of the sole 2. After walking for a long time, the heel is easily worn.

[0040] The second air cushion 3 is mainly used to increase the buffer between the heel and the sole 2, so that the heel feels more comfortable. The third air cushion 4 is mainly used to prevent hard objects on the ground from directly hitting the cooling device, and the third air cushion 4 can protect the cooling device. The first air cushion 5 is mainly used to increase the buffer between the forefoot and the sole 2, so as to prevent the forefoot from being worn.

[0041] The first air cushion 5, the second air cushion 3 and the third air cushion 4 can all be made of polyurethane material. Polyurethane material has excellent comprehensive performance. It has high strength, high elasticity, high compression strength, excellent tear resistance, wear resistance, oxygen and ozone resistance, solvent resistance (such as non-polar solvents hexane, heptane, paraffin oil, etc., which have almost no effect on polar solvent polyurethane, and even under high temperature conditions, the swelling of polyurethane in non-polar solvents is very small), and light weight.

[0042] In this embodiment, the cooling device includes a cooling box 6 ; the cooling box 6 is provided with a mounting groove 7 for mounting the power supply component, and a coolant is provided inside the cooling box 6 .

[0043] In detail, the cooling box 6 can be made of metal material, and the cooling box 6 is located inside the boot sole 2. The cooling box 6 is filled with coolant. The coolant consists of water, antifreeze, and additives, and the antifreeze component is ethylene glycol. The coolant is prepared by adding a small amount of anti-foaming, anti-corrosion and other comprehensive additives. Since ethylene glycol is easily soluble in water, the freezing point of the coolant can be arbitrarily adjusted, and its lowest freezing point can reach -68°C. The coolant has the characteristics of high boiling point, low foaming tendency, good viscosity-temperature performance, anti-corrosion and anti-scaling, and has a good use effect.

[0044] The cooling liquid in the cooling box 6 is not full, and when a person walks, the cooling liquid can flow in the cooling box 6. When the power supply component is heated, the heat is transferred to the surface of the cooling box 6, and the flowing cooling liquid carries away the heat of the cooling box 6, and the heat is slowly consumed during the flow of the cooling liquid.

[0045] In this embodiment, the power supply assembly includes a first contact switch 8 and a mobile power supply 9; the mobile power supply 9, the heater and the first contact switch 8 are connected in series; the mobile power supply 9 is slidably arranged in the installation groove 7; and the first contact switch 8 is arranged at the bottom of the installation groove 7.

[0046] In detail, the first contact switch 8 is used to connect the mobile power supply 9 with the internal circuit. The mobile power supply 9 is detachably connected to the boot body, and the operator needs to regularly check or replace the mobile power supply 9 to avoid safety hazards caused by quality problems of the mobile power supply 9 after long-term use. The model of the mobile power supply 9 can be a 126090 lithium battery. This type of mobile power supply 9 can be charged with a capacity of 8000 mAh and a voltage of 3.7V, which ensures that the electric heating shoe can continue to work for 48 hours, with fast charging and high battery life. In a dry environment with a high risk of electric shock, the safety voltage is specified as 36V; in a humid environment with a high risk of electric shock, the safety voltage is specified as 12V. The mobile power supply 9 of this embodiment is 3.7V, and there will be no danger even if the human body is electrocuted.

[0047] Optionally, the structure of the first contact switch 8 is similar to the positive and negative terminals of the battery connected inside the battery box in the prior art. When the mobile power supply 9 is removed from the heating shoe, the internal circuit of the heating shoe is automatically disconnected.

[0048] In this embodiment, a plurality of first connecting members and a first sealing cover 11 for fixing the mobile power source 9 are further included; the first connecting members pass through the first sealing cover 11 and are connected to the cooling box 6 .

[0049] In detail, the mobile power supply 9 is slidably arranged in the mounting groove 7. In order to prevent the mobile power supply 9 from sliding out of the mounting groove 7 during the movement of the electric hot shoe, the mobile power supply 9 needs to be fixed by the first sealing cover 11. The long side of the mounting groove 7 is in a horizontal state, ensuring that the mobile power supply 9 does not occupy a large space when placed on the shoe sole 2. If the long side of the mounting groove 7 is in a vertical state, the thickness of the shoe sole 2 will increase, and the space utilization rate of the shoe sole 2 will be poor.

[0050] In detail, the first connecting rod 10 can be a bolt, and the cooling box 6 is provided with a threaded hole. The materials of the first connecting rod 10 and the cooling box 6 can both be metal, so as to ensure that the connection strength of the first connecting rod 10 and the cooling box 6 is relatively high after being connected. If the first connecting rod 10 is made of plastic, after the first connecting rod 10 is disassembled for many times, the first connecting rod 10 may be deformed, the thread may be damaged, and even some residues of the first connecting rod 10 may be left in the threaded hole of the cooling box 6, resulting in problems in the connection between the first connecting rod 10 and the cooling box 6.

[0051] The threaded connection ensures that the connection strength between the first sealing cover 11 and the cooling box 6 is high, and prevents external water vapor from entering the installation groove 7 from the connection between the first sealing cover 11 and the cooling box 6. In order to further increase the sealing performance of the connection between the first sealing cover 11 and the cooling box 6, a rubber gasket can be added between the first sealing cover 11 and the cooling box 6. The sealing cover is pressed against the notch of the installation groove 7 by the force, and the gasket reduces the gap between the first sealing cover 11 and the cooling box 6.

[0052] In this embodiment, refer to Figure 1 and Figure 7 , and also includes a manual switch 12; the boot body also includes a boot shaft 1; the manual switch 12 is connected in series with the heater, and the manual switch 12 is arranged on the outside of the boot shaft 1.

[0053] For details, refer to Figure 8 , K1 can be the first contact switch 8, and K2 can be the manual switch 12. The manual switch 12 can be specifically set on the side of the boot shaft 1 close to the boot head. The manual switch 12 is set at this position for easy operation, because the space on the front side of the boot shaft 1 is relatively open and is in a position that is easy to reach by sight. If an obstacle is encountered, the operator can wear the electric heating shoes in time to avoid it. If the obstacle appears from the left, right or back side of the electric heating shoe, the operator may fail to avoid it in time, thereby touching the manual switch 12, causing the heating circuit inside the electric heating shoe to be disconnected, and the process of circuit disconnection is likely to be unnoticed. When the temperature inside the electric heating shoe drops and is noticed, it is too late to reopen the manual switch 12 at this time, because the heater takes a certain amount of time to heat up, and during this period of time, the temperature inside the electric heating shoe will be low.

[0054] Before the operator puts on the heated shoes, the operator can turn on the manual switch 12 to preheat the heated shoes to ensure that the inside of the heated shoes is relatively warm when the foot puts on the heated shoes.

[0055] In this embodiment, the boot body also includes a toe cap; a plush layer is provided on the inner side of the boot shaft 1 and the inner side of the toe cap, and heaters are provided between the inner wall of the boot shaft 1 and the plush layer, between the inner wall of the toe cap and the plush layer, and under the insole.

[0056] Specifically, the plush layer separates the heater from the foot, preventing the heater from directly heating the foot and causing local overheating and burns. The plush layer is mainly made of animal fur, which has a good warming effect and can prevent the heat inside the heated shoe from being lost too quickly. If the plush layer is replaced by other warming layers with smoother surfaces, a large gap may appear between the warming layer and the foot, causing the heat inside the heated shoe to be lost quickly.

[0057] Reference Figure 6The heater is similar in principle to an electric blanket. The heater includes a heat-conducting layer and a resistance wire 13, and the resistance wire 13 is located inside the heat-conducting layer. The resistance wire 13 is woven with glass fiber or polyester yarn, and is wrapped with a flexible electric heating alloy wire (or foil tape), and is coated with a nylon heat-sensitive layer or a special plastic heat-sensitive layer. A copper alloy signal line is then wrapped around the heat-sensitive layer, and a heat-resistant resin is coated on the outermost surface. When the temperature at any point on the heat-conducting layer exceeds a predetermined value, the heat-sensitive layer on the corresponding electric heating wire at that point changes from an insulator to a good conductor, so that the control circuit is turned on and the heater is powered off, achieving the purpose of temperature control and safety protection.

[0058] In this embodiment, if Figure 4 As shown, the boot shaft 1 is provided with a charging connector 15 , and the charging connector 15 is electrically connected to the mobile power source 9 .

[0059] In detail, the charging connector 15 can be a USB connector, and the charging connector 15 is connected to the power supply through an external data cable for charging. It should be noted that the charging connector 15 needs to be connected to the power supply through a power adapter, or connected to the power adapter with a data cable. Because the voltage of the charging power supply is generally a 220V household power supply, and the voltage of the mobile power supply 9 is 3.7V, different voltages need to be converted by an adapter to avoid the charging power supply burning the mobile power supply 9.

[0060] In this embodiment, a plurality of second connecting rods and a second sealing cover for covering the charging connector 15 are further included; the second connecting rods pass through the second sealing cover and are connected to the boot body.

[0061] In detail, the second connecting rod can be a bolt. The second connecting rod is similar to the first connecting rod 10, the second sealing cover is similar to the first sealing cover 11, the boot shaft 1 is provided with a mounting block made of metal material, the mounting block is provided with a threaded hole, and the second connecting rod is threadedly connected to the mounting block. The charging connector 15 is provided on the mounting block. It should be noted that the charging connector 15 and the mounting block are made of the same metal material, and an insulating layer is provided at the connection between the charging connector 15 and the mounting block to prevent the charging line from contacting the mounting block. If the charging connector 15 and the mounting block are formed in one piece, the current will be transferred from the mounting block to the second connecting rod during charging, and the tail of the second connecting rod will be exposed outside the boot shaft 1, which is prone to leakage.

[0062] A rubber pad is provided at one end of the second sealing cover close to the boot shaft 1 . When the second sealing cover is connected to the boot shaft 1 , the rubber pad can prevent water vapor from entering the charging connector 15 .

[0063] In this embodiment, a waterproof layer is provided on the outer surface of the boot body.

[0064] In detail, the waterproof layer can prevent rainwater in the environment from soaking the boot body, prevent a large amount of liquid from contacting the heater, and even cause a short circuit in the internal circuit of the heating shoe.

[0065] The waterproof layer material can be polyurethane. Soft polyurethane has a thermoplastic linear structure. It has better stability, chemical resistance, resilience and mechanical properties than PVC foam material, and has smaller compression deformation. It has good heat insulation, sound insulation, shock resistance and anti-toxic properties. The performance of polyurethane elastomer is between plastic and rubber, and it is oil-resistant, wear-resistant, low-temperature-resistant, aging-resistant, high-hardness and elastic.

[0066] Specifically, the waterproof layer may be made of leather, which may be artificial leather. Artificial leather is also called imitation leather or rubber, which is a general term for artificial materials such as PVC and PU. It is made of foaming or laminating PVC and PU with different formulations on a textile or non-woven base. It can be processed according to different requirements of strength, wear resistance, cold resistance, color, gloss, pattern, etc. It has the characteristics of a wide variety of colors, good waterproof performance, neat edges, high utilization rate and relatively low price compared to genuine leather.

[0067] Leather is wear-resistant and dirt-resistant, has good waterproof effect, and has good thermal insulation effect, ensuring that the heat of the heated shoes is not easily dissipated after heating.

[0068] Example 2

[0069] Please refer to Figure 1 The structure of this embodiment is roughly the same as that of embodiment 1, except that:

[0070] In this embodiment, the charging connector 15, the second connecting rod and the second sealing cover are removed, and solar panels are arranged on the left and right sides of the boot 1, and a voltage converter is arranged inside the boot 1, and the solar panels and the mobile power supply 9 are both electrically connected to the voltage converter. The solar panel converts solar energy into electrical energy, and the electrical energy is transmitted to the mobile power supply 9 through the voltage converter.

[0071] Solar panels are devices that respond to light and can convert light energy into electricity. There are many materials that can produce photovoltaic effects, such as single crystal silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, copper indium selenide, etc. Their power generation principles are basically the same. Now let's take crystalline silicon as an example to describe the photovoltaic power generation process. P-type crystalline silicon can be doped with phosphorus to obtain N-type silicon, forming a PN junction.

[0072] When light shines on the surface of the solar panel, some photons are absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, causing the electrons to jump and become free electrons that gather on both sides of the PN junction to form a potential difference. When the external circuit is connected, under the action of this voltage, current will flow through the external circuit to generate a certain output power. The essence of this process is: the process of converting photon energy into electrical energy.

[0073] Solar panels are greatly affected by light, such as shadows and light angles, so the voltage output by the solar panels is unstable and must be transformed using a voltage converter to ensure that the solar panels can stably charge the mobile power supply 9.

[0074] Example 3

[0075] Please refer to Figure 4 and Figure 5 The structure of this embodiment is roughly the same as that of embodiment 1, except that:

[0076] In this embodiment, the manual switch 12 is removed and replaced by a second contact switch 14. The second contact switch 14 is connected in series with the heater and is disposed on the sole 2 of the boot.

[0077] For details, refer to Figure 8 , K1 can be the first contact switch 8, and K2 can be the second contact switch 14. When the foot puts on the heating shoe, the foot squeezes the second contact switch 14 to close it, and the internal circuit of the heating shoe is connected. The second contact switch 14 ensures that the heating shoe can be put on and heated immediately, works automatically, and is easy to use.
