Description

Technical Field

[0001] This invention relates to the field of sports rehabilitation and physical recovery equipment technology, and in particular to a closed negative pressure cooling device for athletes to quickly cool down and enhance core sensation. Background Technology

[0002] After high-intensity exercise, athletes experience a significant rise in core body temperature within a short period. Failure to implement timely and effective cooling measures can not only negatively impact subsequent performance but also increase the risk of muscle injury and dehydration. Existing cooling devices have several limitations: some devices only target single areas (such as the head and torso), neglecting the efficient thermoregulation of hairless skin areas like the palms and soles, resulting in low cooling efficiency; most products separate physiological cooling from psychological relaxation, failing to consider the interference of external noise on athletes' recovery; furthermore, traditional devices are often structurally dispersed, inconvenient to move, and have exposed components, affecting ease of use and failing to meet the demands of high-frequency scheduling and rapid, short-duration use in competitions. Additionally, existing hand cooling devices are mostly glove-like structures, restricting hand movement and reducing athlete comfort. Therefore, there is an urgent need for an integrated cooling device that is compact, portable, allows for multi-system collaboration, and can simultaneously achieve physiological cooling and psychological relaxation.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, this invention provides a closed negative pressure cooling device for athletes to quickly cool down and enhance core sensation. It is characterized by comprising a closed soundproof chamber 1, a seat assembly 2, a hand negative pressure cooling system 3, a foot negative pressure cooling system 4, a neck cooling assembly 5, a facial cold air spray system 6, and a control system. The components work together through mechanical and electrical connections. The specific structure and connection relationships are as follows: In this embodiment, specifically, the sealed soundproof chamber 1 serves as the external protection and environmental isolation structure of the device. Its outer shell is made of lightweight polyester fiber composite material, the inner layer is composite sound-absorbing cotton, and elastic sealing rings are embedded at the edges. The elastic sealing rings achieve air isolation and sound barrier between the chamber and the outside world, ensuring the sealed environment required by the negative pressure cooling system while reducing external noise interference, providing athletes with a quiet recovery space. The chamber is fixedly connected to the seat assembly 2 to form an integrated structure, ensuring stability during use.

[0027] In this embodiment, specifically, seat assembly 2 provides a supporting base for athletes and serves as a mounting carrier for large components. The main body of the seat is made of high-strength engineering plastic, with an internal sponge lining to enhance comfort. The seat frame is made of aluminum alloy, combining strength and lightweight characteristics. Universal casters 23 are provided at the bottom of the seat for easy movement of the device in competition venues, training bases, and other similar settings. Sufficient installation space is reserved under and on the back of the seat to accommodate larger components such as liquid storage tanks and negative pressure devices 11, preventing exposed components from affecting aesthetics and usability.

[0028] In this embodiment, specifically, the hand negative pressure cooling system 3 is used to achieve efficient cooling of the hands, including a negative pressure device 11, a silicone tube, and a sleeve-type sealed cavity. The sleeve-type sealed cavity is made of nylon fiber and liquid silicone composite, with the skin-contacting part made of nylon fiber to ensure wearing comfort. The cavity has an open sleeve structure without a front-end closure, allowing athletes' hands to move freely without restriction. The sealed cavity is equipped with pressure and temperature sensors, and the cavity edges can be adjusted for tightness according to different hand sizes to ensure the cavity's airtightness. The sealed cavity 12 contains a semiconductor cooling material 13 for providing a cooling medium. The negative pressure device 11 is installed below the seat assembly 2 and is sealed to the sleeve-type sealed cavity through a silicone tube. The silicone tube is hidden inside the seat assembly 2 and is not exposed. The semiconductor cooling material 13 includes a cooling chip, a heat dissipation device, a temperature control system, and a power supply. When the negative pressure device 11 is working, it creates a negative pressure environment in the sealed cavity 12 through the silicone tube, allowing the skin of the hand to fully contact the semiconductor cooling material 13, accelerating blood circulation and heat dissipation. The negative pressure value in the sealed cavity is 35-45 mmHg, and the cooling temperature of the semiconductor cooling material is between 18-22°C.

[0029] In this embodiment, specifically, the foot negative pressure cooling system 4 has the same structure as the hand negative pressure cooling system 3, including a negative pressure device 11 of the same specifications, a silicone tube, and a sleeve-type sealed cavity. The sleeve-type sealed cavity of the foot is fixed to the athlete's foot through a zipper at the ankle to achieve a sealed connection. Its negative pressure device 11 is also installed under the seat assembly 2 and is connected to the foot sealed cavity through a silicone tube. The silicone tube is hidden inside the seat and works in conjunction with the hand negative pressure cooling system 3 to achieve negative pressure cooling of the feet simultaneously.

[0030] In this embodiment, specifically, the neck cooling component 5: targets the carotid artery area for cooling, uses a flexible structure made of liquid silicone to fit the neck curve and ensure comfortable wear; the component has built-in phase change material and copper heat sink, the phase change material can stably release cold energy, and the copper heat sink is used to enhance heat dissipation efficiency; it is convenient for athletes to wear and adjust; a silent fan 16 is provided on one side of the component, the silent fan 16 is set corresponding to the copper heat sink, and by accelerating air flow, it further improves the neck cooling effect, and the silent design avoids generating additional noise.

[0031] In this embodiment, specifically, the facial cooling mist system 6 is used to spray low-temperature atomized gas onto the face to enhance core cold perception. It includes a liquid tank, an atomizer, and a cooling nozzle 18. The liquid tank and atomizer are fixedly installed below the seat assembly 2. The liquid tank is used to store the cooling medium, and the atomizer is used to atomize the cooling medium. The cooling nozzle 18 is located inside the sealed soundproof chamber 1 and is directed towards the athlete's face. The liquid tank, atomizer, and cooling nozzle 18 are connected in series via silicone tubes. The silicone tubes are hidden inside the chamber and the seat to achieve sealed transmission of the cooling medium and prevent exposure. When the atomizer is working, it atomizes the cooling medium in the liquid tank and delivers it to the cooling nozzle 18 through the silicone tubes to spray low-temperature atomized gas onto the face.

[0032] In this embodiment, specifically, the control system coordinates the collaborative work of various systems and includes a circuit board, a lithium battery 17, a switch 20, a charging port 21, and a light indicator 22. The circuit board is installed inside the seat assembly 2 and is electrically connected to the negative pressure device 11, the semiconductor cooling material 13, the atomizer, and the silent fan 16 via wires, enabling the start-up, stop, and parameter adjustment of each component, such as negative pressure intensity, cooling temperature, and spray time. The lithium battery 17 provides power to the entire device, and the charging port 21 is located on the side of the seat for charging the lithium battery 17. The switch 20 controls the overall start-up and stop of the device, and the light indicator 22 is electrically connected to the circuit board, displaying the device's operating status, such as running, standby, and low battery, through different light colors.

[0033] In this embodiment, the specific collaborative working logic of each system is as follows: After the device is started by the control system, the circuit board synchronously activates the negative pressure device 11, the semiconductor cooling material 13, the atomizer, and the silent fan 16; the negative pressure device 11 forms negative pressure in the sealed cavity of the hands and feet, so that the hands and feet are in full contact with the semiconductor cooling material 13, accelerating heat dissipation; the phase change material in the neck cooling component 5 releases cold energy, and the copper heat sink and the silent fan 16 work together to enhance the cooling effect, rapidly cooling the carotid artery area; the facial cold air spray system 6 atomizes the cooling medium through the atomizer and sprays it onto the face through the cold air nozzle 18, enhancing the cold sensation; the sealed soundproof chamber 1 isolates external noise and air, providing a stable environment for the cooling process, ultimately achieving the synergistic effect of rapid decrease in the athlete's core body temperature and enhanced core sensation.

[0034] When this invention is in operation: Athletes need to cool down and recover quickly after high-intensity exercise: The athlete opens the entrance of the sealed soundproof chamber 1, sits on the sponge lining of the seat assembly 2, and secures the neck cooling assembly 5 to the neck through the zipper opening, adjusting the zipper to a comfortable and sealed state; puts both hands into the sleeve-type sealed cavity of the hand negative pressure cooling system 3, and both feet into the sleeve-type sealed cavity of the foot negative pressure cooling system 4, adjusting the tightness of the cavity through the zipper opening to ensure the airtightness of the hands, feet and the cavity, while ensuring that the hands can move freely.

[0035] The athlete activates the device via switch 20 on the side of the seat, and indicator light 22 illuminates green, indicating that the device is in operation. The control system's circuit board simultaneously activates various components: the negative pressure device 11 is activated, creating a stable negative pressure in the sealed cavities 12 of the hands and feet through silicone tubes, allowing the skin of the hands and feet to fully contact the internal semiconductor cooling material 13, accelerating heat dissipation; the phase change material in the neck cooling assembly 5 begins to release cold energy, and the copper heat sink conducts the cold energy to the neck skin, while the silent fan 16 starts to accelerate airflow and improve neck cooling efficiency; the atomizer of the facial cooling mist system 6 is activated, atomizing the cooling medium in the reservoir and delivering it through silicone tubes to the cooling nozzles 18, which then spray low-temperature atomized gas intermittently and directionally onto the athlete's face, enhancing core cold perception.

[0036] Throughout the cooling process, the sealed soundproof chamber 1 isolates external noise through the inner layer of sound-absorbing cotton and the elastic sealing ring on the edge, providing a quiet environment for athletes; the silicone tubes of each connecting component are hidden inside the seat and chamber, with no exposed parts, ensuring the device's aesthetics and safety.

[0037] After cooling is complete, the athlete turns off switch 20, the indicator light 22 goes out, and the device stops operating. The athlete then removes the neck cooling component 5 through the zipper opening, removes both hands and feet, and closes the compartment entrance. If the lithium battery 17 is low on power, the indicator light 22 will light up red, and the lithium battery 17 can be charged through the charging port 21 for future use.

[0038] In summary, this device, designed specifically for athletes, is a closed negative pressure cooling system that provides rapid cooling and enhanced core sensation. Based on a sealed, soundproof chamber 1, it integrates and compacts various functional systems using the seat assembly 2. The hand negative pressure cooling system 3 and the foot negative pressure cooling system 4 provide synergistic cooling through negative pressure and refrigeration for highly efficient heat regulation areas. Combined with targeted heat conduction cooling from the neck cooling assembly 5 and enhanced cold sensation from the facial cold air spray system 6, and coordinated by a control system, this forms an integrated cooling system of "multi-part synchronous action + environmental isolation assistance." Its sleeve-style open cavity and zippered wearing opening ensure both comfort and adaptability, while concealed piping and universal wheels 23 achieve convenient mobility and a clean structure. Ultimately, it achieves rapid core body temperature reduction, simultaneous physiological recovery and psychological relaxation, effectively meeting the short-term, high-frequency usage needs during breaks in competitions and post-training recovery.

[0039] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
