Abstract
Description
Technical Field
[0001] This invention relates to the field of personal heatstroke prevention and cooling equipment, and in particular to a physical cooling device. Background Technology
[0002] In the high temperatures of summer, especially for those working outdoors in agriculture or industry, the risk of heatstroke is high, which seriously affects work efficiency and health. Common methods for preventing heatstroke include wearing sun hats, using ice packs, and applying cold compresses. While these methods can temporarily alleviate the heat, they suffer from problems such as short-lasting cooling effects, inconvenience, and inability to provide sustained cooling.
[0003] For example, traditional ice packs or cold compresses require frequent replacement of ice or compresses, and their cooling range is limited, failing to provide continuous cooling for critical areas such as the head and neck. Furthermore, many existing portable cooling devices rely on electrically driven semiconductor cooling or fan heat dissipation, which are complex in structure, consume high energy, and are limited in use without power, making them unsuitable for prolonged outdoor operation. Summary of the Invention
[0004] The main objective of this invention is to provide a physical cooling device that can effectively solve the problems of existing personal heatstroke prevention and cooling methods such as ice packs and cold compresses, which have short cooling duration, require frequent replacement of cooling media, and are inconvenient to use. It also addresses the issues of existing portable cooling devices, which rely on external power sources, have complex structures, high energy consumption, are not suitable for long-term outdoor work, and generally lack convenient drinking water functions.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A physical cooling device includes a circulating water storage mechanism and a cooling cap mechanism. The circulating water storage mechanism includes a back box module and a circulating water pump disposed therein. The cooling cap mechanism includes a cap body and a mesh circulating water cap fixed therein. The back box module and the mesh circulating water cap are connected by a double adhesive circulating connecting hose. The circulating water pump drives cooling water to circulate between the back box module and the mesh circulating water cap.
[0006] Preferably, the back box module includes a box shell and a foamed thermal insulation interlayer covering the outside of it.
[0007] Preferably, the top of the outer shell of the box is provided with a sealing cover, and a sealing plug is fixed at the bottom of the sealing cover. The sealing plug is snapped into the top of the inner cavity of the outer shell of the box.
[0008] Preferably, the outer shell of the box is provided with a spring buckle on the rear side for fixing the sealing cover.
[0009] Preferably, the circulating water pump is electrically connected to a rechargeable lithium battery, and the outer wall of the housing is provided with a power display screen.
[0010] Preferably, the cooling cap mechanism further includes a head-mounted hose connection plug located on the rear side of the mesh circulating water cap for connecting the double-adhesive circulating connection hose.
[0011] Preferably, the double-adhesive circulating connecting hose is branched at the shoulder position and connected to a branched water intake hose, the end of which is provided with a water intake valve and a drinking spout.
[0012] Preferably, the back box module has an inlet / outlet water connector at the top front end for connecting to the double adhesive circulation hose.
[0013] Preferably, the back box module is equipped with a shoulder strap, forming a backpack-style structure.
[0014] Preferably, the back box module has a waist-mounted structure, and its size and capacity are smaller than those of a backpack-style structure.
[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention provides a physical cooling device that tightly fits a mesh circulating water cap to the user's head and uses a circulating water pump to drive cooling water to flow continuously in the fine pipe network, thereby increasing the contact area and heat exchange efficiency between the cooling medium and the head, thus achieving rapid, uniform and continuous physical cooling of the head, effectively relieving the stuffy feeling of the head in high-temperature environments, and improving the cooling effect and comfort.
[0016] 2. This invention provides a physical cooling device with a circulating water storage mechanism that adopts a backpack or waist-mounted design. It has an internal foam insulation layer that can effectively slow down the melting rate of the internal ice. Combined with a circulating water pump powered by a rechargeable lithium battery, it can work stably for a long time in an environment without an external power source, meeting the cooling needs of outdoor workers in high temperatures for several hours in a row, thus improving the device's endurance and practicality.
[0017] 3. This invention provides a physical cooler, in which a branched water intake hose, water intake valve, and drinking spout are integrated into the circulating hose system, allowing users to directly drink the cooling water in the circulating system during the cooling process. This integrates cooling and drinking functions, solving the problem of inconvenient drinking in high-temperature environments and eliminating the need to carry additional drinking equipment, thus enhancing the convenience and versatility of use.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0021] like Figure 1 As shown, the present invention provides a physical cooling device, which mainly includes a cooling cap mechanism 1 and a circulating water storage mechanism 2. The circulating water storage mechanism 2 adopts a backpack design, which is convenient for users to carry when working outdoors. The cooling cap mechanism 1 is connected to the circulating water storage mechanism 2 through a double adhesive circulating connecting hose 14 to form a closed circulating water circuit.
[0022] like Figures 1 to 4 As shown, the cooling cap mechanism 1 includes a cap body 11 and a mesh circulating water cap 12 fixed inside it. The mesh circulating water cap 12 is made of multiple flexible thin tubes woven into a mesh shape. The thin tubes are preferably medical silicone tubes with an inner diameter of about 2-3 mm, and are formed to fit the curved surface of the head by parallel winding or warp and weft weaving. The mesh circulating water cap 12 can be sewn to the lining of the cap body 11 or fixed to the inside of the cap body 11 using detachable buckles or Velcro straps, thereby ensuring that it can fit evenly and tightly against the user's scalp for efficient heat exchange. Its shape fits snugly against the inner cavity of the cap body 11, allowing it to conform closely to the user's head. A head-mounted flexible tube connector 13 is located on the back of the mesh circulating water cap 12. This connector has an inlet and an outlet, which are connected to the circulating water storage mechanism 2 via two double-adhesive circulating flexible tubes 14. The surface of the double-adhesive circulating flexible tubes 14 is provided with adhesive strips that can be attached and fixed along the shoulders, back, etc., to prevent the tubes from tangling or shifting. Specifically, the adhesive strips can adopt a structure similar to Velcro, with the napped strip sewn or heat-pressed onto the surface of the tube, and matching hook-and-loop strips sewn onto the shoulder of the user's clothing or equipped with an independent adhesive base, thereby achieving a secure, adjustable, and comfortable fixation of the tubes.
[0023] To further enhance practicality, a branched water-drawing hose 15 is branched off from a double-adhesive circulating connecting hose 14 located at the shoulder. This branching is achieved via a T-joint, preferably connected to the water inlet hose flowing from the outlet of the circulating water pump 213 to the cooling cap mechanism 1. The branched water-drawing hose 15 extends to the user's chest, with a water-drawing valve 16 and a drinking spout 17 at its end. The water-drawing valve 16 controls the water flow, and the drinking spout 17 can be used with a dedicated water bottle or for direct drinking. When the user is thirsty, opening the water-drawing valve 16 allows direct access to chilled water from the circulating system, achieving both cooling and drinking functions. The operating logic is as follows: during water draw, a portion of the cooling water driven by the circulating water pump 213 is diverted through the branched hose. Because the pump operates continuously and the diverted water volume is relatively small, it does not affect the main circulation loop's continuous cooling function for the head.
[0024] The circulating water storage mechanism 2 includes a back box module 21, which comprises a casing 211 and a foamed insulation layer 212 covering the outside. The foamed insulation layer 212 effectively blocks external heat and slows down the melting rate of ice inside the casing. A circulating water pump 213 is installed inside the casing 211. The circulating water pump 213 is preferably a miniature DC pump with a rated flow rate of 1-3 liters / minute and a head of 1-2 meters of water column. Its low power consumption, matched with the built-in rechargeable lithium battery, ensures that the cooling water overcomes flow resistance in the circulation system, which includes several meters of flexible hose and a fine mesh cap, achieving stable and effective circulation. The circulating water pump 213 is electrically connected to the rechargeable lithium battery. A power display screen 214 is provided on the outer wall of the casing 211 to display the remaining battery power in real time, facilitating timely charging by the user. The inlet and outlet of the circulating water pump 213 both pass through the outer shell 211 and the foamed insulation layer 212, and are connected to the inlet / outlet connector 24 located at the top front of the tank. The inlet / outlet connector 24 adopts a quick-connect structure, which facilitates connection or disconnection with the double-adhesive circulating connection hose 14. The quick-connect structure can be one of a snap-fit male / female connector, a threaded quick-tight connector, or a push-pull self-locking connector. During connection, it achieves a reliable seal through the internal sealing ring to prevent water leakage.
[0025] The top of the outer shell 211 is provided with a sealing cover 23, and a sealing plug plate 231 is fixed at the bottom of the sealing cover 23. The sealing plug plate 231 is embedded in the top of the inner cavity of the outer shell 211 to achieve a seal. A spring buckle 215 is provided on the rear side of the outer shell 211 to lock the sealing cover 23 and prevent it from being opened accidentally when carried.
[0026] The front of the backpack module 21 is equipped with a shoulder strap 22, forming a complete backpack structure. The internal volume of the case is approximately 5 liters, which can hold about 10 kilograms of ice and a small amount of recycled water. It is recommended that the recycled water be pre-cooled cold water, and the volume ratio of ice to water should be approximately 3:2 for initial use. To further delay ice melting, a porous water- and ice-proof filter can be installed in the middle of the case cavity, dividing the case space into upper and lower layers. The upper layer holds the ice, and the lower layer stores the recycled water, thus extending the overall runtime by reducing the direct contact area between the ice and the recycled water. In actual testing, at a high temperature of 35℃, this capacity can provide continuous cooling for approximately 3 hours. If whole blocks of ice are used instead of crushed ice, combined with a good insulation design, the runtime can be further extended.
[0027] In addition, to further slow down the melting of ice, a water-proof and ice-proof filter can be installed inside the box to temporarily isolate the ice from the circulating water, reduce direct contact, and thus extend the overall service life.
[0028] This invention can also be designed as a waist-mounted structure, with a smaller box volume and capacity than the backpack type. Its overall size is similar to that of a traditional mining lamp, making it convenient for use while riding a bicycle or walking in short-term high-temperature environments. The connection method and working principle of the waist-mounted structure are the same as those of the backpack type, with only the box size and carrying method being different.
[0029] The mesh circulating water cap 12 can be used alone with common hats such as safety helmets and straw hats, making it highly versatile. If it is difficult to produce the mesh circulating water cap 12 in one piece, a cap ring keel with an inner groove can be produced first, then the hose can be bent and embedded into the groove for fixation, and finally the head hose connector 13 can be installed, achieving standardized and modular assembly. The cap ring keel can be made of flexible plastic or rubber into a ring shape, with a single continuous spiral groove or multiple parallel grooves on its inner side. During installation, the cap is embedded along the groove and can be fixed by clips, adhesive, or covering it with a layer of fabric. Finally, the two ends of the cap are led out and connected to the head hose connector 13.
[0030] This invention can also be used in conjunction with special clothing such as biochemical suits and medical protective suits. By simply leaving a tube hole with a sealing structure at the back of the clothing, the hose of the cooling cap mechanism 1 can be introduced into the clothing to achieve whole-body or localized circulating cooling.
[0031] The working principle of this physical cooling device will be explained in detail below.
[0032] like Figure 1-4As shown, the user first adds an appropriate amount of cold water to the back box module 21 and fills it with ice cubes. Then, the user puts on the sealing cap 23 and fastens the spring buckle 215. The user then puts the cooling cap mechanism 1 on their head, securely connects the double adhesive circulation hose 14 to the inlet / outlet water connector 24, and attaches the hose along the shoulder. The user then turns on the circulating water pump 213. Driven by the pump, the ice water flows out of the back box module 21, enters the mesh circulating water cap 12 through a double adhesive circulation hose 14, and undergoes heat exchange on the head. The warm water then returns to the back box module 21 through another hose, is cooled by the ice cubes, and is circulated again. During this process, the user can open the water valve 16 at any time to drink the cold water. The system can continue to run until the ice cubes melt completely or the battery is depleted.
