Description

Technical Field

[0001] The present invention relates to the technical field of functional slippers, in particular to slippers for use in bathrooms, specifically to self-heating foot bath health-care waterproof slippers and outsoles thereof. Background Art

[0002] Nowadays, most of the slippers used in hotels are disposable slippers.

[0003] From an environmental perspective, disposable slippers are non-recyclable and, when discarded in large quantities, become a significant source of environmental pollution. Because they are often made of non-biodegradable plastic or synthetic fibers, they take a long time to decompose in the natural environment. This not only consumes significant land resources but also can cause soil pollution and impact the ecological balance. The amount of waste generated annually by disposable hotel slippers is staggering, placing increasing pressure on the environment.

[0004] In terms of resource utilization, the production of disposable slippers consumes a significant amount of precious resources. Because disposable slippers lack functionality beyond basic walking comfort, such as comfort, slip resistance, waterproofing, and health benefits, their limited functionality leads to their seldom-removed use. This, in turn, consumes significant amounts of raw materials. Discarding slippers after a single use results in significant resource waste, running counter to current principles of efficient resource utilization and a circular economy.

[0005] From the perspective of user experience, existing disposable slippers cannot meet consumers' growing demand for comfortable and healthy products. They do not fit the shape of the feet when worn, pose a risk of slipping, are inconvenient to use in humid environments, and cannot provide other complex functions, affecting guests' living experience in the hotel and reducing the hotel's overall service quality image.

[0006] As for industry development, despite national regulations restricting the use of disposable consumables, years of established consumer habits make this eradication difficult. Furthermore, the lack of functionally upgraded, recyclable, and mutually beneficial alternatives for both hotels and guests further hinders the industry's transition toward greener, more sustainable practices, hindering its long-term healthy development.

[0007] Therefore, disposable hotel slippers have long been non-recyclable, difficult to degrade, occupy land, and damage the ecology. Moreover, the slippers themselves have a single function but consume a large amount of raw materials and are discarded after one use. In addition, when users use them, they do not fit the foot shape, are not non-slip and waterproof, and lack other additional functions. At the same time, the industry's consumption habits are difficult to change and there is a lack of ideal alternative products. Summary of the Invention

[0008] In order to solve a series of problems of disposable hotel slippers, such as serious environmental pollution, huge waste of resources, poor user experience and obstruction of industry transformation, the present invention provides a self-heating foot bath health waterproof slipper and its outsole.

[0009] The present invention provides a self-heating outsole of a foot bath health-care slipper, comprising an outsole, wherein the outsole comprises a burr arranged around an upper edge, upper alignment areas are provided at the front ends of both sides of the burr, two connected material bag bins are provided on the upper surface of the outsole, water inlet holes connected to the respective material bag bins are provided at the corners of the two material bag bins on the bottom surface of the outsole, exhaust channels connected to the outside are provided on the left and right sides of each material bag, and outlets of the exhaust channels are located below the upper alignment area.

[0010] During implementation, it includes an outsole with a raised pattern on the bottom surface for anti-skid. Specifically, a text pattern is adopted, and the cross section of the pattern is conical and raised, that is, the cross section of the strokes of the text pattern is conical and raised, which improves the anti-skid effect and reduces wear and tear that causes the anti-skid effect of the sole to decrease. The outsole includes a fin arranged around the upper edge, and upper positioning areas are arranged at the front ends of both sides of the fin. The upper is arranged directly above the upper positioning area. Two connected material bag bins are opened on the upper surface of the outsole. The inner wall of the material bag bin is surrounded by an integrally connected supporting convex, so that the bin wall of the material bag bin is designed with a concave arc, which is embedded in the outer shape of the material bag. The material bag is affected by the sewing process. The edge thickness of the bag is smaller than the central thickness. The supporting convexity is used to support the edge stitching area of the material bag, making the inside of the shoe smoother and improving the user's experience. The material bag bin includes a front material bag bin and a rear material bag bin. The front material bag bin and the rear material bag bin are rectangular. The water flows between the front material bag bin and the rear material bag bin to the two material bag bins; the bottom surface of the outsole is located at the corners of the two material bag bins and is respectively provided with water inlet holes connected to their respective material bag bins. There are two water inlet holes, which are diagonally arranged at the end corners of the material bag bin. The channel of the water inlet hole is inclined toward the inside of the material bag bin, that is, the inner side of the channel of the water inlet hole is lower than the outer side to avoid water backflow. The opening cross-sectional area of each water inlet hole is 4.5~5.5mm 2The size and number of the openings must be appropriate to facilitate the appropriate amount of water entering, so that the material bag reaches the set heating time, avoiding too fast or too slow reaction, resulting in insufficient fumigation time during bathing time, or the fumigation effect is not obvious. There is no restriction on the shape and number of the water inlet holes. Preferably, the water inlet hole is circular with a hole diameter of 2.5mm. Each silo bag has an exhaust channel connected to the outside on both sides. The middle section of the side of the front silo is provided with an exhaust channel, and the front corner of the rear silo is provided with an exhaust channel. The exhaust channel runs through the middle layer of the silo wall, and the exhaust channel is inclined toward the front of the shoe and is located The exhaust channels on the same side are arranged in parallel, and the outlets of the exhaust channels are located below the shoe upper alignment area, that is, the outlets of the exhaust channels are not opposite to the user's exposed feet, so as to avoid excessive pressure of hot steam rushing to the side of the user's feet and burning the user; a weight-reducing bin is provided on the outer periphery of the material bag bin on the outsole, the purpose of which is to reduce the weight of the slippers by hollowing out, while ensuring that they are lighter when worn and reducing material costs; the bottom of the weight-reducing bin is connected to the outside world through a water leakage hole, which is used to discharge water leaking into the weight-reducing bin. The exhaust channel is arranged between the two weight-reducing bins, and the exhaust channel and the weight-reducing bin are not interconnected.

[0011] The present invention provides a self-heating foot bath health-care waterproof slipper, comprising the above-mentioned outsole, wherein a material bag bin of the outsole is filled with a material bag, a midsole with an upper is sewn to the fin of the outsole, and an insulation layer covering the material bag bin is lined between the midsole and the outsole. The insulation layer is laid above the material bag that generates hot steam when in contact with water, that is, the hot steam generated when in contact with water is discharged through an exhaust channel, and the user's feet will not be directly scalded due to excessive temperature. The front ends of the midsole are sewn to the upper on both sides, and the stitching is located directly above the upper's alignment area, coordinating the exhaust duct's exit with the upper. This prevents steam from directly hitting the exposed side of the foot. Both the midsole and upper are made of a composite waterproof fabric with a waterproof rating exceeding 8,000 mmH2O, a water vapor adhesion rate that's less than 10% of that of conventional fabrics, an abrasion resistance exceeding 100,000 revolutions on the Martindale test, and a breathability of no less than 3,000 g / m2 / 24 hours. Specifically, the composite waterproof fabric comprises a layer-by-layer waterproof coating, a base fabric layer, a neoprene foam layer, and a plastic film waterproof layer. The composite waterproof fabric comes into direct contact with the user's foot, providing a soft touch and retaining moisture after showering. This effectively reduces moisture residue in the slippers and feet, preventing prolonged dampness and reducing foot discomfort caused by moisture. It also prevents hot steam from reaching the user's foot, penetrating the upper, and potentially causing burns.

[0012] The material bag includes a material bag, which is packaged with non-woven fabric. A dividing pressure line is provided at the center line of the material bag to avoid extrusion, rupture, powder leakage, and heat failure caused by the material bag and unevenness inside the shoe, which affects the user's experience.

[0013] The bag is filled with heating powder and medicinal powder. Once heated, the medicinal powder penetrates the skin and other pathways, providing multiple health benefits. The heat from the fumigation dilates blood vessels in the feet, accelerating blood circulation and promoting smoother blood flow throughout the body. Furthermore, the combination of thermal stimulation and medicinal properties stimulates meridians and acupuncture points, warming the meridians, dispelling cold, relieving pain, and alleviating travel fatigue. The bag contains 20-30 parts of calcium oxide powder, which acts as the primary heat source and rapidly generates heat when exposed to water; 5-15 parts of 100-mesh aluminum powder, which accelerates and increases heat generation; 1-10 parts of sodium carbonate powder, which acts as a buffer to prevent overreaction and overheating, ensuring a more stable and controlled heating process; 5-15 parts of red mineral salt, which consumes oxygen and inhibits the expansion of gases generated by the heat, enhancing safety; and 1-5 parts of moxa, 1-5 parts of radix schizonepetae powder, and 1-5 parts of safflower pollen, which release the medicinal properties through the heated steam, creating a therapeutic effect when applied to the feet. Among them, the heating powder reacts with water to generate heat and expand, and the main component of red mineral salt is K3[Fe(CN)6]. Red mineral salt dissolves when it comes into contact with water, providing expansion space for the heating powder, avoiding excessive expansion of the material bag, and improving the flatness of the shoe. In addition, red mineral salt has bactericidal and anti-inflammatory effects, which can help clean the skin of the feet, prevent and improve inflammation problems of the feet, and maintain the health of the foot skin; moxa has a calming and sleep-inducing effect. Through fumigation, it stimulates the meridians and acupoints of the feet, regulates the function of the nervous system, relieves mental tension, helps relax the body and mind, and improves sleep quality; bone-penetrating grass powder has the effects of dispelling wind and dampness, relaxing muscles and activating blood circulation. It can penetrate into the skin, tendons and bones, help relax the ankle and sole muscles, relieve joint flexion and extension, muscle soreness, and reduce fatigue. Safflower pollen improves blood circulation, prevents blood stasis, and improves blood circulation under the effect of warmth.

[0014] Furthermore, the amount of heating powder filled in the material bag is matched with the water inlet hole, which is sufficient to provide the user with heating after a second bath.

[0015] During use, the user wears slippers to enter the bathing area. Under normal circumstances, the user's range of movement in the bathing area is small. Most of the time, the user is in a natural standing state with both feet in a separate position. Only very rarely does the user move to adjust the body position. The shower water flows through the floor of the bathing area, and part of the water enters the material bag bin through the water inlet hole, flows to the front material bag bin and the rear material bag bin, penetrates into the material bag from the bottom of the material bag, reacts with the heating powder, and generates hot steam. The hot steam is ejected outward from the exhaust channel to form a hot steam environment in the user's foot area, producing a fumigation effect. In particular, the hot steam ejected from the rear material bag bin is sprayed onto the shoe upper to avoid directly hitting the exposed skin.

[0016] Typically, after a tiring day, when a user enters a hotel, especially after extensive walking or prolonged sitting, blood circulation in the legs decreases, and the user usually wishes to soak their feet in hot water. However, most hotels, especially budget hotels, only offer showers. Due to public health conditions and the time of use, even if a hotel provides a bathtub, most users do not use it. Compared to foot soaking, where the drug or water components are absorbed through contact with the skin, fumigation drugs exist in the form of ions in the steam, making them more easily absorbed through the skin. In a water bath, the skin acts as a barrier, and its absorption of substances in the water is relatively limited. Furthermore, hot steam can quickly raise skin temperature, allowing capillaries to dilate more fully, thus promoting blood circulation more significantly. However, the water temperature is usually lower than the fumigation temperature, and the effect on vasodilation and blood circulation is relatively weak. Furthermore, when using this device, the user can walk normally without being restricted by the container. Simply wearing slippers in the shower can achieve a relaxing effect, and the operation is simple and convenient.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a self-heating foot bath health-care waterproof slipper and its outsole. Through material improvement, unique structural design, and added functional settings, the device not only adds physical therapy and health-care functions and improves the user experience, but also achieves the economic benefit of reducing the use of disposable slippers and plastic bath slippers and the social benefit of significantly reducing environmental pollution.

[0018] This device generates heat when it comes into contact with water during bathing. The aperture design of the water inlet hole ensures that it can be reused twice. The material bag that generates hot steam when it comes into contact with water can be used to apply heat to the soles of the feet, achieving the function of foot bath health care. At the same time, the high temperature during the hot compress can also make the slippers dry quickly after bathing, and can be worn in the room as ordinary disposable slippers, killing two birds with one stone, thereby significantly reducing the current use of disposable slippers and plastic bath slippers in hotels.

The font and pattern height is 0.5mm, which is used for anti-slip. The cross-section of the pattern is conical and raised to improve the anti-slip effect. The various directions of the text strokes are used as anti-slip lines, and they can also serve as product introductions and beautiful decorations. It meets the requirements of SCOF (dry friction coefficient) > 0.5 and DCOF (wet friction coefficient) > 0.4 in the Chinese standard (GB / T 3903.6), ensuring wearing safety. The side of the outsole is also provided with a pattern to clearly indicate the outlet position of the exhaust channel 6. Figure 2 Not marked in the middle; the outsole 10 includes a burr 5 arranged around the upper edge, the thickness of the burr is 3mm and the width is 7.5mm. The burr 5 is only arranged around the upper edge to reduce the weight of the outsole. The front ends of the two sides of the burr 5 are provided with upper alignment areas 9, and the upper 11 is arranged directly above the upper alignment area 9. The upper surface of the outsole 10 is provided with two connected material bag bins, the outsole thickness is 12mm, and the depth of the material bag bin is 10mm. The inner wall of the material bag bin is surrounded by an integrally connected support convex 4. The material bag placed in the material bag bin is affected by the stitching process. The edge thickness of the material bag is less than the central thickness. The support convex 4 is used to support the edge stitching area of the material bag, making the inside of the shoe smoother and improving the user's use experience. The material bag bin includes a front material bag bin 1 and a rear material bag bin 2. The front material bag bin 1 and the rear material bag bin 2 are rectangular, and the front material bag bin 1 and the rear material bag bin 2 are connected. The bottom surface of the outsole 10 is located at the corners of the two material bag bins, each of which is provided with a water inlet hole 3 connected to the respective material bag bins. There are two water inlet holes 3, which are arranged diagonally at the end corners of the material bag bins. Each water inlet hole 3 is circular with a hole diameter of 2.5mm. An exhaust channel 6 connected to the outside is opened on the left and right sides of each material bin bag. An exhaust channel 6 is opened in the middle section of the side of the front material bag bin 1, and an exhaust channel 6 is opened at the front corner of the rear material bag bin 2. The exhaust channel 6 runs through the middle layer of the material bag bin wall, and the exhaust channel 6 is inclined toward the front of the shoe and is located on the same side. The exhaust channel 6 is arranged in parallel. The outlet of the exhaust channel 6 is located below the shoe upper alignment area 9, that is, the outlet of the exhaust channel 6 is not opposite to the user's exposed feet, so as to avoid excessive pressure of hot steam rushing to the side of the user's feet and burning the user; the outsole 10 is located on the outer periphery of the material bag bin and is provided with a weight-reducing bin 7, and the bottom of the weight-reducing bin 7 is connected to the outside world through a water leakage hole 8, which is conducive to reducing the weight of the outsole, ensuring light and comfortable wearing, reducing material costs and draining water leaking into the weight-reducing bin 7, and the exhaust channel 6 is arranged between the two weight-reducing bins 7, and the exhaust channel 6 and the weight-reducing bin 7 are not interconnected. Example 2

[0027] A kind of self-heating foot bath health care waterproof slippers, such as Figures 1 to 5 As shown, it includes the outsole 10 of Example 1, the material bag bin of the outsole 10 is filled with material bags, a midsole 12 with an upper 11 is sewn on the flash 5 of the outsole 10, and a heat insulation layer 13 covering the material bag bin is lined between the midsole 12 and the outsole 10. The heat insulation layer 13 is laid above the material bags that generate hot steam when they come into contact with water. That is, the hot steam generated when it comes into contact with water is discharged through the exhaust channel 6, and the soles of the user's feet will not be directly scalded due to excessive temperature. At the same time, a steam cage effect is formed around the feet to heat the instep; The front ends of the midsole 12 are sewn to the upper 11 on both sides, and the sewing part is located directly above the upper alignment area 9, that is, the outlet of the exhaust channel 6 is located at the same position as the upper 11, to prevent the ejected steam from being directly sprayed onto the exposed side of the foot. The midsole 12 and the upper 11 are both made of composite waterproof fabric. The waterproof performance of the composite waterproof fabric is greater than 8000mmH2O level, and the wear-resistant Martindale test can reach more than 100,000 revolutions; specifically, the composite waterproof fabric includes a waterproof coating, a base fabric layer, a neoprene foam layer, and a plastic film waterproof layer that are laminated layer by layer. The composite waterproof fabric is in direct contact with the user's feet, providing the user with a soft touch. It does not retain moisture after the user takes a bath, can effectively reduce the residue of moisture in the slippers and feet, avoid the feeling of being wet for a long time, and reduce the foot discomfort caused by moisture. At the same time, it prevents the ejected hot steam from being sprayed onto the user's feet, and the hot steam penetrates the upper 11, causing burns to the user.

[0028] The material bag includes a material bag, which is packaged with hydrophilic non-woven fabric. A dividing pressure line is provided at the center line of the material bag to prevent it from breaking and leaking during walking, resulting in functional failure and unevenness inside the shoe, affecting the user's experience.

[0029] The bag is filled with heating powder and medicinal powder. After the medicinal powder reacts with water, it can enter the human body through the skin penetration and other channels through the combined action of heat and medicinal power, and play a multi-faceted health care effect. On the one hand, the heat during fumigation can dilate the blood vessels in the feet, speed up blood circulation, and allow blood to flow more smoothly to the whole body. On the other hand, through warm stimulation and medicinal power, it stimulates the meridians and acupoints, warms the meridians and dispels cold, dredges the meridians and relieves pain, and reduces fatigue caused by the journey. The bag is filled with 25g calcium oxide powder, 10g 100 mesh aluminum powder, 5g sodium carbonate powder, 10g red mineral salt, 2g moxa, 1g radix safflower powder, and 1g safflower pollen.

[0030] Among them, the heating powder reacts with water to generate heat and expand, while the red mineral salt dissolves when it comes into contact with water, providing expansion space for the heating powder, avoiding excessive expansion of the material bag, and improving the flatness of the shoe. In addition, red mineral salt has bactericidal and anti-inflammatory effects, which can help clean the skin of the feet, prevent and improve inflammation problems of the feet, and maintain the health of the skin of the feet; moxa has a calming and sleep-inducing effect. Through fumigation, it stimulates the meridians and acupoints of the feet, regulates the function of the nervous system, relieves mental tension, helps relax the body and mind, and improves sleep quality; bone-penetrating grass powder has the effects of dispelling wind and dampness, relaxing muscles and activating blood circulation. It can penetrate into the skin, tendons and bones, help relax the ankle and sole muscles, relieve joint flexion and extension, muscle soreness, and reduce fatigue. Safflower pollen improves blood circulation, prevents blood stasis, and improves blood circulation under the effect of warmth.

[0031] Furthermore, the amount of heating powder filled in the bag is matched with the water inlet hole 3, which is sufficient for the user to use it twice, ensuring secondary heating.

[0032] During use, the user wears slippers to enter the bathing area. Under normal circumstances, the user's range of movement in the bathing area is small. Most of the time, the user is in a natural standing state with both feet in a separate position. Only a very small number of times does the user move to adjust the body position. The shower water flows through the floor of the bathing area, and part of the water enters the material bag bin through the water inlet hole 3, flows to the front material bag bin 1 and the rear material bag bin 2, and penetrates into the material bag from the bottom of the material bag to react and generate hot steam. The hot steam is ejected outward from the exhaust channel 6, forming a hot steam environment in the user's foot area, producing a fumigation effect. In particular, the hot steam ejected from the rear material bag bin 2 is sprayed toward the shoe upper 11 to avoid directly hitting the exposed skin.

[0033] According to investigation and statistics, the bathing time of hotel users is usually 15 to 30 minutes, so the test was conducted with bathing time of 15 minutes and 30 minutes.

[0034] After repeated tests, the user wears slippers and enters the bathing area and starts bathing. After a few seconds, water enters from the water inlet 3. After 3 to 4 minutes, hot steam can be observed to be discharged from the outlet of the exhaust channel 6. At the same time, the sole of the foot feels the temperature of the midsole rise and begins to heat up. After 4 minutes, a mist-like steam cage appears near the user's feet, accompanied by a strong smell of Chinese herbal medicine.

[0035] Experimental group 1 After 15 minutes, the user walks out of the bathing area and moves to the dry area, and the warmth can still continue for about 20 minutes (Chinese medicine believes that the appropriate duration of foot massage is 30 minutes). Then it can be observed that the amount of hot steam discharged from the outlet of the exhaust channel 6 gradually decreases, and the temperature of the midsole begins to gradually drop. The user feels that the midsole is no longer hot and puts the slippers to stand still at room temperature. Then, a second test is conducted, and the above bathing steps are repeated to restart the timing. It can also be observed that after a few seconds, water enters from the water inlet 3. When it lasts for 3 to 4 minutes, hot steam can be observed to be discharged from the outlet of the exhaust channel 6. At the same time, the sole of the foot feels the temperature of the midsole rises and begins to heat up. When it lasts for 4 minutes, a mist-like steam cage appears near the user's feet, and the duration exceeds 15 minutes.

[0036] Experimental Group 2 After 30 minutes, the user walks out of the bathing area and moves to the dry area, and the warmth can still continue for about 10 minutes (Chinese medicine believes that the appropriate duration of foot massage is 30 minutes). Then it is observed that the amount of hot steam discharged from the outlet of the exhaust channel 6 gradually decreases, and the temperature of the midsole begins to gradually drop. The user feels that the midsole is no longer hot and puts the slippers to stand still at room temperature. Then, a second test is conducted, and the above bathing steps are repeated to restart the timing. It can also be observed that after a few seconds, water enters from the water inlet 3. When it lasts for 3 to 4 minutes, hot steam can be observed to be discharged from the outlet of the exhaust channel 6. At the same time, the sole of the foot feels the temperature of the midsole rises and begins to heat up. When it lasts for 4 minutes, a mist-like steam cage appears near the user's feet, and it lasts for nearly 20 minutes.

[0037] In all of the above tests, the temperature of the midsole 12 after stable heating of the material pack was 33-44°C, which is within the human body's tolerance range, and the sole of the foot feels warm and slightly hot. Moreover, after the first use, the material pack still reached the same temperature after contact with water during the second use, demonstrating a good and long-lasting hot compress therapeutic effect.

[0038] The scope of protection claimed by the present invention is not limited to the above specific embodiments. For those skilled in the art, the present invention may have various variations and modifications. Any modifications, improvements and equivalent substitutions made within the concept and principle of the present invention should be included in the scope of protection of the present invention.
