Description

Technical Field

[0001] The utility model relates to the technical field of cooling products, in particular to a cooling hoop. Background Art

[0002] In the hot summer, outdoor workers such as construction workers and food delivery riders are exposed to high temperatures for a long time, and their bodies are prone to heat stress. In order to avoid heat stroke and other heat-related diseases, they need a convenient and efficient cooling device to alleviate the body's heat stress response.

[0003] There are many convenient and efficient portable cooling devices on the market to meet the needs of different consumers. Common portable cooling devices include neck fans, handheld fans, cooling sprays and cooling hoops. Cooling hoops are usually small, light and easy to carry. They can be easily worn on the head, neck and other parts that need cooling. They do not take up too much space and will not affect normal work or activities. Compared with other cooling devices, the cooling method of cooling hoops is usually milder and will not cause excessive stimulation or harm to the body.

[0004] The cooling hoops on the market currently have various designs, but generally they all include a closed outer layer filled with cooling fillers. This outer layer not only protects the internal fillers, but also prevents direct contact with the skin to ensure safety in use. Although common fillers such as water and gel materials can achieve cooling effects, their durability and convenience need to be improved. For example, water needs to be frozen in advance before it can play its cooling effect when used, so the cooling effect will be greatly reduced and it is not convenient to use; and although gel materials can be used directly at room temperature, their cooling effect and duration are limited, and in high temperature environments, gels are prone to leakage or deformation, which not only affects the cooling effect, but may also cause inconvenience to users. Utility Model Content

[0005] The utility model aims to provide a cooling hoop, which can solve the problem that the existing cooling hoop cannot maintain a stable cooling effect for a long time.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is: the hoop body of the cooling hoop includes a hoop-shaped layer and a cooling layer, the hoop-shaped layer is a waterproof layer, the cooling layer is filled in the hoop-shaped layer, the cooling layer is a phase change material that is solid at room temperature, the phase change material is only n-octadecane, and the hoop-shaped layer is a fully enclosed sealing structure.

[0007] In the above-mentioned cooling hoop technical solution, a more specific technical solution may also be: the hoop-shaped layer is a soft and elastic skin-friendly material.

[0008] Furthermore, the temperature-reducing layer expands the hoop-shaped layer.

[0009] Furthermore, the cross section of the main body of the hoop-shaped layer in the expanded state is circular.

[0010] Furthermore, the two opposite inner sides of the open end of the hoop body include an inner conical opening and an outer trumpet-shaped opening, the inner conical opening is connected to the small end of the outer trumpet-shaped opening, and the opening end of the large end of the outer trumpet-shaped opening is larger than the opening degree of the large end of the inner conical opening.

[0011] Furthermore, the outer side of the opening end of the hoop body is bent outward.

[0012] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0013] 1. The structure is simple. The hoop body adopts a waterproof hoop-shaped layer and a cooling layer filled therein. n-octadecane is used as the material of the cooling layer, so that the cooling hoop can quickly reduce the temperature of the wearing part. n-octadecane has a high latent heat value and a suitable phase change temperature, so that the cooling hoop can continue to provide a cooling effect for a long time, which means that whether in the hot summer or during high-intensity activities, the cooling hoop can effectively reduce body temperature and provide users with a cool and comfortable use experience; compared with cooling products that need to be pre-frozen, this cooling hoop does not require any pretreatment and can be used directly, which greatly improves the convenience of use; because the hoop-shaped layer adopts a fully enclosed sealing structure, it effectively prevents the leakage of n-octadecane or direct contact with the external environment, ensures the safety of the user, and improves the durability of the cooling effect. Therefore, the cooling hoop can maintain a stable cooling effect for a long time without frequent replacement or replenishment of cooling materials.

[0014] 2. The hoop layer uses skin-friendly materials, which not only improves the wearing comfort of the cooling hoop, but also ensures the stability of the cooling layer.

[0015] 3. The design of the cooling layer and the expansion hoop layer makes the two tightly combined to form a stable whole, which enhances the structural strength of the cooling hoop and prevents the cooling material from leaking or shifting during use. This ensures that the cooling effect can continuously and stably act on the wearing part, and improves the consistency and reliability of the cooling effect; the hoop body with a circular cross-section can provide a more comfortable and natural wearing experience, reduce discomfort when wearing, and allow users to remain comfortable during long-term use.

[0016] 4. The inner and outer trumpet-shaped openings on the inner side of the hoop body opening end are designed so that the hoop can be easily inserted and removed through the gradually enlarged opening, which reduces the resistance when wearing, making it easier to put on and take out the cooling hoop when wearing, and improving the convenience of wearing; the opening degree of the large end of the outer trumpet-shaped opening is larger than the opening degree of the large end of the inner conical opening. This design ensures the convenience of wearing and enhances the stability of the cooling hoop after wearing. When the cooling hoop is inserted, the larger opening degree of the outer trumpet-shaped opening can provide better support and fixing effect, preventing the cooling hoop from slipping or shifting during use.

[0017] 5. The design of the outer side of the opening end bending outward is more in line with the natural curve of human hand when holding. Users can hold the cooling hoop more easily and operate it stably to open or close it, which enhances the ease of opening, makes the operation simple and quick, and improves the user experience.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0022] Figure 1 and Figure 2 The hoop body 1 of the cooling hoop shown is composed of a hoop-shaped layer 4 and a cooling layer 5. The hoop-shaped layer 4 is the outer layer of the cooling hoop 5. It is a fully enclosed sealing structure. It must meet the requirements of being a waterproof layer and the requirements of comfortable wearing. Therefore, it can be made of soft and elastic skin-friendly materials, such as one of silicone, thermoplastic elastomer, rubber, polyurethane, or a material in which silicone and thermoplastic elastomer are mixed in a ratio of 1 to 3:1. These materials are not only waterproof, but also have excellent elasticity and comfort, and can fit the user's skin closely without causing a sense of oppression to the skin. The cooling layer 5 is filled in the hoop-shaped layer 4, and its composition is n-octadecane, which is solid at room temperature. As a phase change material, n-octadecane can undergo a phase change near the human body temperature, from solid to liquid, absorbing and storing a large amount of heat, thereby achieving a cooling effect. Since n-octadecane dissolves slowly, it is more suitable as an auxiliary cooling tool for outdoor activities in summer. It can quickly and continuously reduce the temperature of the wearing part without any pretreatment. Whether it is scorching sun or high-intensity activities, it can provide a cool feeling and effectively help users maintain a comfortable body temperature.

[0023] In terms of structural design, the cooling layer 5 expands the hoop-shaped layer 4 so that the two are closely combined, thereby improving the durability of the cooling effect. Meanwhile, the cross section of the main body of the hoop-shaped layer 4 in the expanded state is circular, and this design can better fit the curve of the wearing part, especially the parts with more complicated human body curves such as the shoulder and neck. The cooling hoop can fit more closely on the skin of these parts, reduce the gap between the skin, and improve the tightness and comfort of wearing. In other embodiments, the hoop body 1 can also be designed as a common flat structure to meet the needs and preferences of different users. Whether it is a circular or flat structure, it should be ensured that the main surface of the hoop body 1 is smooth to provide a more comfortable and smooth wearing experience.

[0024] In order to facilitate the user to wear and remove the cooling hoop, the open end of the hoop body 1 adopts a special design. Specifically, the two opposite inner sides of the open end of the hoop body 1 include an inner conical opening 2 and an outer trumpet-shaped opening 3, the inner conical opening 2 and the small end of the outer trumpet-shaped opening 3 are connected, and the open end of the large end of the outer trumpet-shaped opening 3 is larger than the opening degree of the large end of the inner conical opening 2. This design allows the opening to be easily opened and closed while maintaining a certain elasticity, which is convenient for user operation. In addition, the outer side of the open end of the hoop body 1 is also bent outward, which not only increases the aesthetics, but also makes it more convenient for the user to hold and open the opening. In other embodiments, considering the wearing requirements of different users, the open end can also be closed by a zipper or Velcro.

[0025] The cooling hoop has a simple structure, is easy to use, has a long-lasting and stable cooling effect, is highly comfortable to wear, and can be used directly without pretreatment, greatly improving the convenience of use. Whether it is outdoor workers or other people who need to be outdoors for a long time, it can help these people easily cope with hot weather.
