Technical Field

[0001] The present invention relates to the technical field of shoes, and more particularly to a pair of shoes with a heating system. Background Art

[0002] Shoes are essential in daily life. In cold weather, maintaining a comfortable temperature inside shoes is difficult, especially for the elderly, who are prone to cold feet. To address this issue, shoes with heating functions have been designed in the prior art. For example, publication No. CN115251523B discloses smart snowshoes equipped with a heating cloth covering the sole surface. The heating cloth contains heating strips that electrically heat the shoe to increase the temperature inside, thereby enhancing comfort in cold environments.

[0003] However, there are still some defects in the above-mentioned existing technologies. The heating cloth is in direct contact with the feet. Although it can quickly increase the temperature, shoes are worn for a long time. Even if the instantaneous temperature of the heating strip is not high, long-term direct contact between the feet and the heating cloth can easily cause low-temperature burns, especially for the elderly and children, whose skin itself has dull perception and is more likely to cause low-temperature burns. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a shoe with a heating system. The heating element does not directly contact the foot, but instead slowly and comprehensively improves the stability of the shoe by delivering heated hot air, avoiding the problem of low-temperature burns that may occur due to direct contact.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a shoe with a heating system, comprising a sole, an insole and an upper, including a heating component, an air supply component being provided on the upper, and the air supply component transports external air to the heating component through a flexible air pipe, and a plurality of release holes being provided on the insole, and the hot air heated by the heating component is released into the interior of the shoe through the release holes.

[0007] The present invention is further configured as follows: the heating assembly includes a diverter component arranged at the front end of the heating plate, and the diverter component is used to divert the air delivered by the air supply assembly into the heating channel.

[0008] The present invention is further configured such that: the insole is arranged on the supporting edge, and the position of the release hole corresponds to the position of the heating channel.

[0009] The present invention is further configured as follows: the outer side of the trachea is wrapped with a thermal insulation layer, and the heating component includes an electric heating wire arranged in the thermal insulation layer and extending along the trachea.

[0010] The present invention is further configured as follows: a guide plate is provided in the sole, a guide groove is provided in the guide plate, and the air pipe is communicated with an inlet end provided on the guide groove.

[0011] The present invention is further configured as follows: the air supply assembly includes a shell and a pump body, the bottom of the shell is provided with an air outlet, one end of the pump body is connected to the air outlet, and the other end is connected to the air pipe.

[0012] The present invention is further configured as follows: the air supply assembly also includes a control unit and an energy storage unit, the control unit, the energy storage unit and the pump body are electrically connected, the control unit is used to control the opening and closing of the pump body, and the energy storage unit is detachable.

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] This embodiment discloses a shoe with a heating system, such as Figure 1-7 As shown, the shoe comprises a sole 1, an insole 2, and an upper 3. This embodiment is characterized in that it further comprises a heating assembly 4. The upper 3 is provided with an air supply assembly 5, which transports external air to the heating assembly 4 via a flexible air tube 51. The insole 2 is provided with a plurality of release holes 21, through which the hot air heated by the heating assembly 4 is released into the interior of the shoe. Through the above structure, the heating assembly 4 does not directly act on the wearer's foot, but instead cooperates with the air supply assembly 5 to generate hot air, gradually creating a warmer and more comfortable temperature environment inside the shoe. This avoids the problem of low-temperature burns that can occur when the foot is directly heated by heating pads, heating wires, and other methods in the prior art.

[0027] Further, as a first embodiment of the present invention, referring to Figure 1-2The heating component 4 includes a heating plate 41 arranged in the sole 1. The heating plate 41 can be made of a winding heating wire. A plurality of supporting ridges 412 are provided above the heating plate 41. A heating channel 413 is formed between the supporting ridges 412. The heating channel 413 allows air to flow and heat. The bottom of the supporting ridge 412 can be made of a hard heat-conducting metal material, so that it can also absorb the heat of the heating plate 41, so that the air in the heating channel 413 can be heated in three directions, and the heating efficiency is higher. At the same time, the part above the supporting ridge 412 that contacts the insole 2 needs to be made of a flexible material, such as rubber, to reduce the discomfort of the foot caused by the harder supporting ridge 412. Furthermore, the insole 2 is arranged on the supporting ridge 412, and the position of the release hole 21 corresponds to the position of the heating channel 413, that is, several are opened along the direction of the heating channel 413. When wearing the shoe, the insole 2 is supported by the supporting ridges 412, isolating the foot from the heating plate 41 below, thereby isolating the heating plate 41 from the foot. The release holes 21 then deliver the hot air in the heating channel 413 into the shoe through the small gap between the foot and the insole, gradually raising the temperature inside the shoe.

[0028] Furthermore, in order to allow the air to enter the heating channel 413 better, the heating component 4 includes a diverter component 42 arranged at the front end of the heating plate 41, and the diverter component 42 is used to divert the air sent by the air supply component 5 into the heating channel 413. In this way, the air is diverted, so that the air can enter the heating channel 413 accurately, and the flow rate of the air is reduced to a certain extent by diversion, so that the time the air stays in the reheating channel 413 is prolonged, and the heating effect is better. Accordingly, as a preference, a corresponding bending passage can also be provided in the diverter component 42 to reduce the air flow rate by extending the air path. This is particularly applicable in some high-altitude cold environments where the outside air temperature is very low and a longer heating time is required. A small solenoid valve for switching the air path can be provided in the diverter component 42, so that it is convenient to select a longer or shorter air path according to needs.

[0029] Further, as a second embodiment of the present invention, referring to Figure 3The outside of the air tube 51 is wrapped with a thermal insulation layer 6, and the heating component 4 includes a spirally wound electric heating wire 61 arranged inside the thermal insulation layer 6 and extending along the air tube 51. Through the above structure, the heating component 4 can directly heat the air tube 51, which is simpler in structure. However, the air flow speed in the air tube 51 is relatively fast and cannot be adjusted. It is suitable for use in scenarios where the ambient temperature is not low. Since the sole 1 does not have components such as a heating plate, a guide plate 7 is directly provided in the sole 1. A guide groove 71 is provided in the guide plate 7. The air tube 51 is connected to an inlet end 711 provided on the guide groove 71. The hot air is sent into the guide groove 71 and then released into the shoe through the release hole 21 on the insole 2.

[0030] Further, refer to Figure 1 and Figure 5-6 The air supply component 5 includes a shell 52 and a pump body 53. An air outlet 521 is provided at the bottom of the shell 52. One end of the pump body 53 is connected to the air outlet 521, and the other end is connected to the air pipe 51. The pump body 53 can adopt a piezoelectric pump in the prior art, which has low working noise. A filter is provided at the air outlet 521 for filtering. At the same time, the air outlet 521 is provided at the bottom for better air intake. If it is provided at the top, the air outlet 521 is easily blocked by trouser legs and the like. At the same time, the air supply component 5 also includes a control unit 54 and an energy storage unit 55. The control unit 54, the energy storage unit 55 and the pump body 53 are electrically connected. The control unit 54 is used to control the opening and closing of the pump body 53. Figure 5 In the embodiment, the control unit 54 also includes a touch screen 541, which displays the operating status of the pump body 53, the remaining power, etc. The energy storage unit 55 is detachable, preferably a lithium battery. A cover is provided on the housing 52 to enable the detachable energy storage unit 55, facilitating its replacement. A depleted battery can be recharged externally and replaced promptly to achieve long-term heating and ensure long battery life. A charging port is also provided on the housing 52, through which the energy storage unit 55 can be directly charged.

[0031] Further, refer to Figure 2 and Figure 4 In order to prevent the release hole 21 on the insole 2 from being exposed for a long time and causing blockage, a replacement pad 8 is provided above the insole 2. The replacement pad 8 has a valve hole 81 at the position corresponding to the release hole 21. The valve hole 81 is made of an elastic and flexible material. Figure 2 In the partially enlarged structure in FIG, the valve hole 81 of the replacement pad 8 closes the release hole 21 in the normal state. When a certain air pressure is formed in the heating channel 413 (which can be the air pressure of heating expansion or the air pressure pumped in by the pump body), the air flow along the direction of the arrow can push the valve hole 81 open (as shown in FIG. Figure 2 The hot air is sent into the shoes. Figure 4In order to ensure that the replacement pad 8 and the insole 2 are not misplaced, a card slot 22 is provided on the insole 2, and a card-in portion 82 is provided on the replacement pad 8, so that the two can be positioned in a card. At the same time, a plurality of replacement pads 8 can be provided for replacement.

[0032] Furthermore, the present invention is provided with a temperature sensor inside the shoe, and the temperature sensor is used to detect the temperature inside the shoe. Figure 7 The temperature sensor can feedback the temperature inside the shoe, so that the control unit can better control the operation of the heating component and the pump body. The working principle of the present invention can be Figure 7 Simply put: first, the energy storage unit supplies power to each component, and then the person inputs the corresponding temperature requirement in the human-computer interaction part. The control unit determines whether to start the heating component and the pump body based on the temperature feedback from the temperature sensor. After starting, the pump body inhales external air, and then forms hot air through the air pipe and heating component. The hot air is sent into the inside of the shoe to achieve heating. When the temperature reaches the requirement, the control unit can suspend heating.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
