TECHNICAL FIELD

[0001] The present application mainly relates to the technical field of footwear manufacturing, in particular to a waterproof cotton boot. BACKGROUND

[0002] In the field of footwear products, cotton boots are widely used as a kind of footwear in cold seasons. Traditional cotton boot manufacturing materials often focus on warmth retention performance. For example, natural fiber fabrics such as cotton and wool have good warmth retention effect, but they have strong water absorption. Once in contact with water, these materials will quickly absorb and retain water, resulting in a damp interior of the cotton boots, which not only affects the comfort of wearing, but also may cause foot health problems after long-term wearing.

[0003] Therefore, in order to improve the waterproof performance of cotton boots, most of the existing cotton boots are made of full-rubber material. Although the waterproof performance is excellent, the weight is heavy, the air permeability is poor, and the feet are easily stuffy after long-term wearing. Moreover, the use of thick and heavy materials increases the overall weight of the cotton boots, which increases the burden of the wearer when walking and easily causes fatigue. At the same time, some cotton boots rely on simple fabric treatment or surface coating to achieve a certain degree of waterproof, but the waterproof effect is often limited. When in contact with water for a long time or in a humid environment, water can easily penetrate into the interior of the cotton boots, resulting in wet feet, which not only affects the comfort of wearing, but also may cause health problems.

[0004] Therefore, in view of the above technical problems, there is a lack of a cotton boot that has waterproof performance and can ventilate the interior of the cotton boot to increase comfort. CONTENT OF THE INVENTION

An opening is arranged on the side of the fixing column 15 facing the pneumatic cavity 14. Figure 2 Figure 3 The transmission assembly 3 comprises a transmission plate 31 and a pressing rod 32. The transmission plate 31 is movably embedded in the fixing groove 13. The top of the transmission plate 31 elastically abuts against the bottom of the upper sole 11. Two pressing rods 32 are fixed to the bottom of the transmission plate 31 and are symmetrically arranged on both sides of the transmission plate 31. The end of the pressing rod 32 penetrates through the opening of the fixing column 15 and extends into the pneumatic cavity 14. A reset spring 33 is arranged between the end of the pressing rod 32 and the inner wall of the fixing column 15, which is used for resetting the transmission plate 31.

[0040] The pneumatic assembly 4 is installed in the pneumatic cavity 14. The pneumatic assembly 4 comprises an air bag 41, an air inlet pipe 42 and an air guide pipe 43. The air bag 41 is fixed in the pneumatic cavity 14 and is located directly below the transmission plate 31. One end of the air inlet pipe 42 is connected to the air bag 41, and the other end of the air inlet pipe 42 extends to the outside of the sole 1 and is provided with a dust cover 421. The dust cover 421 is provided with micropores that only allow gas to pass through, preventing external dust from entering the pneumatic assembly 4. One end of the air guide pipe 43 is connected to the air bag 41, and the other end of the air guide pipe 43 extends into the breathable cavity 21. One-way valves 44 are arranged at both ends of the air bag 41. The one-way valve 44 at the air inlet pipe 42 allows external gas to flow into the air bag 41 in one direction. The one-way valve 44 at the air guide pipe 43 allows the gas in the air bag 41 to flow into the breathable cavity 21 in one direction.

[0041]

[0042] As shown in the accompanying drawings, the sole 1 adopts a split design, comprising an upper sole 11 and a lower sole 12. The bottom of the upper sole 11 is provided with a fixing groove 13. The top of the lower sole 12 is provided with a pneumatic cavity 14 at the corresponding position. The fixing groove 13 and the pneumatic cavity 14 are connected through a fixing column 15. The top of the fixing column 15 extends into the fixing groove 13, and the bottom of the fixing column 15 is fixed to the bottom surface of the pneumatic cavity 14. An opening is arranged on the side of the fixing column 15 facing the pneumatic cavity 14.

The input end of the micro switch 55 is provided with a trigger rod 56 inserted into the micro switch 55. One end of the trigger rod 56 penetrates the fixed slot 13 and abuts against the bottom of the transmission plate 31. When the transmission plate 31 is pressed downward by the heel, the trigger rod 56 is pushed, triggering the micro switch 55 to close the circuit and start the heating of the heating sheet 51. When the transmission plate 31 is reset, the trigger rod 56 rebounds, breaking the circuit, ensuring that the heating function is only activated when the user wears the cotton boots and walks, avoiding misoperation.

[0044] As shown in the accompanying drawings Figure 6 The outer wall of the shoe sole 1 is provided with a limiting slot 17, and the limiting slot 17 is connected with a limiting piece 6. The limiting piece 6 is arc-shaped and made of rubber. The limiting piece 6 covers the outer side of the heating switch 54 and is provided with limiting protrusions 61 at both ends for clamping the limiting slot 17. The limiting piece 6 can be quickly disassembled by pressing or prying, which facilitates the operation of the heating switch 54. The design of the limiting piece 6 not only prevents accidental touch of the heating switch 54, but also considers the convenience of operation.

[0045] Working principle:

[0046] When the user walks, the heel periodically presses the transmission plate 31, which drives the pressing rod 32 to press the air bag 41. When the air bag 41 is pressed, the internal gas is unidirectionally transported to the air permeable cavity 21 through the air guide pipe 43, causing the air pressure in the air permeable cavity 21 to rise and triggering the waterproof and air permeable film 22 to conduct air exhaust. When the air bag 41 is reset, external air is supplemented into the air bag 41 through the air inlet pipe 42, realizing cyclic pneumatic. In this process, the waterproof and air permeable film 22 dynamically adjusts the air permeability and waterproof function under the pressure difference.

[0047] At the same time, when the user walks, the heel abuts against the transmission plate 31, which in turn abuts against the transmission plate 31 and triggers the micro switch 55 to close the circuit and start the heating of the heating sheet 51. When the transmission plate 31 is reset, the trigger rod 56 rebounds, breaking the circuit, ensuring that the heating function is only activated when the user wears the cotton boots and walks, avoiding misoperation.

[0048] The embodiments are only illustrative of the present application, and are not intended to limit the present application, and those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, but as long as the modifications are within the scope of the present application, they are protected by the patent law.
