Description

Technical Field

[0001] The present application relates to the field of health care equipment, and in particular to a foot soaking device. Background Art

[0002] Foot soaking is a popular health care method. Soaking your feet in hot water can help relax the body, relieve fatigue, promote blood circulation and improve sleep quality.

[0003] In the existing technology, most people use simple plastic or metal basins to soak their feet. Although these traditional foot soaking methods are simple and easy to use, they have obvious shortcomings. The main problem is that they cannot keep the water warm. The water temperature drops rapidly in a short period of time. Users need to constantly add hot water or change the water, which is cumbersome and affects the foot soaking experience.

[0004] In this regard, a Chinese patent document (publication number: CN218044875U) discloses a multifunctional foot soaking bucket, which is designed to solve the problem that traditional foot soaking tools cannot maintain water temperature. The device includes components such as a heating device, a temperature sensor, and a control device. By real-time monitoring and adjusting the water temperature, the effect of long-term constant temperature foot soaking is achieved. However, due to the presence of the heating device, temperature sensor and control system, the overall size of the device is large and the weight is heavy, which is not convenient to carry. Especially in scenarios such as outdoor work and camping that require lightness and mobility, it is not convenient to use such power-dependent equipment. Utility Model Content

[0005] To this end, the present application provides a foot soaking device to solve the problem in the prior art that the foot soaking bucket is large in size, heavy in weight and difficult to carry.

[0006] In order to achieve the above objectives, this application provides the following technical solutions:

[0007] A foot soaking device comprises a cylinder and a base connected to one end of the cylinder, wherein the cylinder and the base form a holding cavity for holding hot water, and the cylinder comprises, from its inner wall to its outer wall, a waterproof layer, a phase change layer connected to the waterproof layer, and a leak-proof and heat-resistant layer connected to the phase change layer and away from the waterproof layer.

[0008] Optionally, the inner side of the waterproof layer is connected to a waterproof and moisture-proof coating, and a heat insulation layer is provided between the waterproof layer and the phase change layer.

[0009] Optionally, the cylinder is formed with a plurality of first folds along its circumferential direction for folding and storing the cylinder, and the base is formed with a plurality of second folds passing through its center, and the plurality of second folds are evenly distributed along the circumferential direction of the base.

[0010] Optionally, the cylinder is detachably connected to a connecting belt, and one end of the connecting belt away from the cylinder is detachably connected to a cylinder cover for covering the top of the cylinder.

[0011] Optionally, the outer wall of the cylinder is connected to a male Velcro patch, both ends of the connecting belt are connected to female patches that match the male Velcro patch, and the cylinder cover is connected to the male Velcro patch.

[0012] Optionally, the height of the cylinder is 40-48 cm, and the diameter of the cylinder is 30-38 cm.

[0013] Optionally, the thermal insulation adjustment range of the phase change layer is 38-42°C, and the phase change temperature is 40°C.

[0014] Compared with the prior art, this application has at least the following beneficial effects:

[0015] When in use, pour hot water into the holding cavity, and the phase change layer of the cylinder will play its temperature regulating role according to the temperature change of the hot water. When the temperature of the hot water is higher than the phase change point of the phase change layer, the phase change material will absorb excess heat, thereby avoiding the water temperature from being too high and regulating the temperature to a comfortable range; when the water temperature gradually decreases and is lower than the phase change point of the phase change layer, the phase change material will release the heat absorbed before, keeping the water temperature near the optimal temperature tolerated by the human body. The phase change point of the phase change layer is designed to be around 40°C, and there is a temperature difference of several degrees above and below this temperature. This setting can effectively match the tolerance temperature of the human body, allowing the phase change material to better absorb and release heat, thereby extending the heat preservation time and improving the comfort of foot soaking;

[0016] The waterproof layer is used to prevent the hot water in the accommodating cavity from penetrating to the outside of the cylinder, ensuring the overall sealing and waterproof performance of the foot bath device and preventing hot water leakage. In addition, the waterproof layer can also protect the phase change layer from direct contact with water, thereby maintaining the stability and long-term effectiveness of the phase change material. The leak-proof and heat-resistant layer is located on the outside of the phase change layer and is mainly responsible for resisting the influence of the external environment temperature on the inside of the cylinder. The phase change layer is located between the waterproof layer and the leak-proof and heat-resistant layer, and can be effectively protected by these two layers to prevent external factors from directly affecting the phase change material.

[0025] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0026] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0027] refer to Figure 1-5 The present application discloses a foot soaking device, comprising a barrel 1 and a base 2 connected to one end of the barrel 1. The barrel 1 and the base 2 form a receiving cavity 3 for receiving hot water. The barrel 1 comprises, from its inner wall to its outer wall, a waterproof layer 12, a phase change layer 14 connected to the waterproof layer 12, and a leak-proof and heat-resistant layer 15 connected to the phase change layer 14 and away from the waterproof layer 12.

[0028] When in use, pour hot water into the accommodating cavity 3, and the phase change layer 14 of the barrel 1 will play its temperature regulating role according to the temperature change of the hot water. When the temperature of the hot water is higher than the phase change point of the phase change layer 14, the phase change material will absorb excess heat, thereby avoiding the water temperature from being too high and regulating the temperature to a comfortable range; when the water temperature gradually decreases and is lower than the phase change point of the phase change layer 14, the phase change material will release the heat absorbed before, keeping the water temperature near the optimal temperature tolerated by the human body. The phase change point of the phase change layer 14 is designed to be around 40°C, and there is a temperature difference of several degrees above and below this temperature. This setting can effectively match the tolerance temperature of the human body, allowing the phase change material to better absorb and release heat, thereby extending the heat preservation time and improving the comfort of foot soaking;

[0029] The waterproof layer 12 is used to prevent the hot water in the accommodating chamber 3 from penetrating to the outside of the barrel 1, ensuring the overall sealing and waterproof performance of the foot bath device and preventing hot water leakage. In addition, the waterproof layer 12 can also protect the phase change layer 14 from direct contact with water, thereby maintaining the stability and long-term effectiveness of the phase change material. The leak-proof and heat-resistant layer 15 is located on the outside of the phase change layer 14 and is mainly responsible for resisting the influence of the temperature of the external environment on the inside of the barrel 1. The phase change layer 14 is located between the waterproof layer 12 and the leak-proof and heat-resistant layer 15, and can be effectively protected by these two layers to prevent external factors from directly affecting the phase change material.

[0030] The base 2 can be made of the same material and multi-layer structure as the cylinder 1 to maintain consistent thermal insulation and waterproof performance. However, since the base 2 is usually located in contact with the ground, its heat dissipation is smaller than that of the cylinder 1. Therefore, in some cases, the base 2 can also be made of a single-layer structure of other waterproof and thermal insulation materials. For example, the base 2 can be made of thermal insulation cotton. This is because the cylinder 1 is in direct contact with the external environment, has a larger surface area, and dissipates heat quickly, resulting in more significant heat loss. Therefore, it is prioritized to design the structure and materials of the cylinder 1 in multiple layers to ensure the best thermal insulation effect of the entire foot bath device.

[0031] The phase change layer 14 is made of phase change material, which is existing technology. The phase change material is preferably a phase change microcapsule material with a phase change point of 40°C. The thermal insulation adjustment range of the phase change layer 14 is 38-42°C. The sealing layer material of the phase change material is one or more of polyester, non-woven fabric, nylon, viscose and other materials.

[0032] In some embodiments, the inner side of the waterproof layer 12 is connected to the waterproof and moisture-proof coating 11 , and a heat-insulating layer 13 is provided between the waterproof layer 12 and the phase change layer 14 .

[0033] Waterproof and moisture-proof coating 11 enhances the sealing performance of waterproof layer 12, providing an additional barrier. Thermal insulation layer 13, located between waterproof layer 12 and phase change layer 14, reduces heat loss through cylinder 1 and protects phase change layer 14, ensuring the phase change material operates within a preset temperature range and extending its heat retention time.

[0034] In some embodiments, the waterproof layer 12 can be made of a water-resistant and flexible material, such as polyvinyl chloride (PVC) or polyurethane (PU), which has good waterproof properties and a certain structural strength. The leak-proof and heat-resistant layer 15 can be made of a high-temperature resistant and stable material, such as polytetrafluoroethylene (PTFE) or silicone. The waterproof and moisture-proof coating 11 can be made of a silicone coating or a nano-coating material. The thermal insulation layer 13 can be made of a material such as foam plastic, polystyrene (EPS), or ceramic fiber.

[0035] In some embodiments, the phase change layer 14 may also be in the form of a coating, and the phase change material is evenly coated on the surface of the waterproof layer 12 by fabric padding technology.

[0036] In some embodiments, reference Figure 5 , Figure 5 It is a diagram of the folding process of the cylinder 1. The arrow indicates the direction of folding and compression. The cylinder 1 is formed with a plurality of first folds 16 along its own circumferential direction to facilitate the folding and storage of the cylinder 1. The base 2 is formed with a plurality of second folds 21 passing through its own center. The plurality of second folds 21 are evenly distributed along the circumferential direction of the base 2.

[0037] When use is finished or needs to be stored, the barrel 1 can be folded along the multiple first folds 16. The design of the first folds 16 allows the barrel 1 to be smoothly folded into a smaller volume, reducing the storage space. At the same time, the base 2 can also be folded and stored along the multiple second folds 21 toward the accommodating chamber 3. These second folds 21 are evenly distributed in the circumferential direction of the base 2 to ensure that the base 2 can be evenly stressed during the folding process, avoiding deformation or damage caused by uneven stress. Through such a design, the entire foot soaking device can be folded to a smaller volume when not in use, which greatly facilitates the user's carrying and storage, and is particularly suitable for occasions such as travel, business trips or outdoor activities where lightweight equipment needs to be carried.

[0038] It should be noted that the plurality of first folds 16 and second folds 21 are typically formed by compression molding or hot pressing. During the compression molding process, the cylindrical body 1 and base 2 are pressed under high temperature and high pressure to form a predetermined folded shape, allowing for easy folding when needed and maintaining the cylindrical shape when poured with hot water when unfolded.

[0039] The cylinder body 1 is detachably connected to a connecting belt 4 , and one end of the connecting belt 4 away from the cylinder body 1 is detachably connected to a cylinder cover 5 for covering the top of the cylinder body 1 .

[0040] The user can conveniently secure the tub cover 5 to the top of the tub body 1 via the connecting strap 4. After initially adding hot water, the user can place the tub cover 5 over the tub body 1 via the connecting strap 4. This design helps reduce heat dissipation from the hot water, allowing the hot water temperature to be regulated more quickly by the phase change layer 14 and reach a comfortable temperature range. Once the phase change layer 14 has completed heat regulation and the water temperature has stabilized within a comfortable range, the user can open the tub cover 5 and begin soaking their feet.

[0041] In some embodiments, the outer wall of the cylinder 1 is connected to a male Velcro patch, both ends of the connecting belt 4 are connected to female patches that match the male Velcro patch, and the cylinder cover 5 is connected to the male Velcro patch.

[0042] When folding and storing the foot soaking device, the user can stick the female stickers at both ends of the connecting belt 4 to the male stickers on the outer wall of the cylinder 1 (the male sticker on the outer wall of the cylinder 1 has a larger area, so the female stickers at both ends of the connecting belt 4 can be stuck to the male sticker on the outer wall of the cylinder 1 at the same time). In this way, the connecting belt 4 can be wrapped around the side of the folded cylinder 1, effectively binding and fixing the folded cylinder 1. This not only makes the folded foot soaking device more compact, preventing it from loosening or unfolding during carrying or storage, but also enhances the portability of the entire device.

[0043] The height of the cylinder 1 is 40-48 cm, and the diameter of the cylinder 1 is 30-38 cm.

[0044] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0045] The present application has been described in a relatively specific and detailed manner through general explanations and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations may be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by such conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
