Description

Technical Field

[0001] This utility model relates to the field of safety helmet technology, and in particular to a heat insulation layer and a double-layer safety helmet based on intelligent temperature control. Background Technology

[0002] The liquid storage space within the insulation layer is narrow and elongated, making it difficult to ensure rapid and complete drainage. Prolonged liquid retention within the insulation layer can damage its inner walls. Traditional safety helmets primarily offer physical impact protection, but they have significant shortcomings in adaptability to complex environments: 1. Low-temperature environment deficiencies: Human body heat is easily lost through the head, and traditional helmets lack active insulation in cold environments, easily leading to body temperature imbalances; 2. High-temperature environment deficiencies: According to occupational health research, prolonged exposure of the head to high temperatures increases the risk of heatstroke for workers; 3. Insufficient breathability: Traditional helmets have poor ventilation, causing workers to sweat easily during prolonged work, and prolonged exposure to hot and humid conditions can lead to scalp health problems.

[0003] There are technical issues such as the inability to completely drain the liquid inside the insulation layer, the difficulty in changing the volume of the insulation layer, and the inconvenience of installing a ventilation structure after setting up an insulation layer inside a double-layer safety helmet based on intelligent temperature control. Utility Model Content

[0004] In view of the technical problems of existing insulation layers where liquid cannot be completely drained and the volume of the insulation layer is not easily changed, the first technical solution of this utility model is proposed.

[0005] This utility model provides a thermal insulation layer, the purpose of which is to solve the technical problems that the liquid inside the thermal insulation layer cannot be completely drained and the volume of the thermal insulation layer is not easily changed.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a heat insulation layer, which includes a heat insulation unit, the heat insulation unit including a heat insulation bag, the heat insulation bag being hemispherical in shape, and a water storage compartment being provided inside the heat insulation bag.

[0007] The connecting component is located on the insulated bag and is connected to the water storage tank.

[0008] The extraction component is located at the end of the connecting component away from the insulation bag. The extraction component seals the connecting component and is located below the connecting component.

[0009] As a preferred embodiment of the insulation layer of this utility model, the connecting component includes a water pipe disposed on the insulation bag and connected to the water storage tank, and a funnel disposed at the end of the water pipe away from the insulation bag.

[0010] As a preferred embodiment of the insulation layer of this utility model, the funnel is made of silicone material.

[0011] As a preferred embodiment of the insulation layer of this utility model, the extraction component includes a fixed cylinder that is detachably disposed on the side of the funnel away from the water pipe, and a pull rod that is slidably disposed inside the fixed cylinder and extends out of the end face of the fixed cylinder away from the funnel.

[0012] The beneficial effects of the insulation layer of this utility model are as follows: water can be injected into the insulation bag through the connecting component, and water can also be drained from the insulation bag through the connecting component. Since the insulation bag is hemispherical, the water storage space inside the insulation bag is small. The water and air in the water storage compartment can be completely extracted through the extraction component. The remaining water can flow along the insulation bag to the extraction component and the connecting component for accumulation, making the inside of the insulation bag cleaner. At the same time, the volume of the insulation bag is reduced after the water and air are extracted, leaving more gaps in the installation space.

[0013] Another objective of this invention is to provide a double-layer safety helmet based on intelligent temperature control, which aims to solve the technical problem that it is inconvenient to install a ventilation structure after the internal insulation layer of the safety helmet is set.

[0014] To solve the above-mentioned technical problems, this utility model also provides the following technical solution: a double-layer safety helmet based on intelligent temperature control, which includes an insulation layer; a safety helmet body unit, the safety helmet body unit including an outer shell, an inner shell located inside the outer shell, and a connecting ring plate disposed on the inner side of the outer shell and connected to the outer side of the inner shell, an installation gap for installing an insulation bag is left between the outer shell and the inner shell, and a water pipe passes through the connecting ring plate.

[0015] The fan unit is located on the outer side of the housing.

[0016] As a preferred embodiment of the double-layer structure safety helmet based on intelligent temperature control of this utility model, the heating wire is provided inside the heat preservation bag and is connected to the fan unit.

[0017] As a preferred embodiment of the double-layer structure safety helmet based on intelligent temperature control of this utility model, the heat preservation bag is provided with a through hole.

[0018] As a preferred embodiment of the double-layer structure safety helmet based on intelligent temperature control of this utility model, the outer shell includes a shell and a limiting plate disposed on the outer peripheral surface of the shell, the limiting plate being an L-shaped plate.

[0019] As a preferred embodiment of the double-layer safety helmet based on intelligent temperature control of this utility model, the limiting plate is provided with a limiting hole and an opening communicating with the limiting hole.

[0020] As a preferred embodiment of the double-layer structure safety helmet based on intelligent temperature control of this utility model, the inner shell is provided with multiple ventilation holes.

[0021] The beneficial effects of this invention's intelligent temperature-controlled double-layer safety helmet are as follows: by clamping the fixing cylinder into the limiting hole, the extraction component is limited and fixed. Then, when the fan is started, the air blows towards the installation gap of the heat-insulating bag after extraction, allowing air to flow within the gap, thus cooling the user's head. It has both heat preservation and ventilation cooling effects, improving the practicality of the safety helmet. Attached Figure Description

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1

[0031] Reference Figure 1 - Figure 2 This is the first embodiment of the present utility model. This embodiment provides a heat insulation layer, including a heat insulation unit 1. The heat insulation unit 1 includes a heat insulation bag 11, which is hemispherical in shape and has a water storage chamber inside.

[0032] A connecting component 12 is disposed on the insulated bag 11 and is connected to the water storage tank. Water can be supplied to and discharged from the water storage tank through the connecting component 12.

[0033] The extraction component 13 is located at the end of the connecting component 12 away from the insulation bag 11. The extraction component 13 seals the connecting component 12 and is located below the connecting component 12. There can be multiple connecting components 12 and extraction components 13, but each connecting component 12 and extraction component 13 corresponds to another. The connecting component 12 facilitates the injection of liquid into the insulation bag 11, while the extraction component 13 facilitates vacuuming after the insulation bag 11 is emptied, causing the air in the water storage chamber to be extracted and the insulation bag 11 to be in a compressed and wrinkled state. At the same time, the residual moisture in the insulation bag 11 will collect in the extraction component 13 through the connecting component 12. When the extraction component 13 is removed, the residual moisture can be cleaned, preventing moisture from remaining in the insulation bag 11 for a long time and causing damage to the inner layer of the insulation bag 11.

[0034] During use: Water can be injected into the insulation bag 11 through the connecting component 12, and water can also be drained from the insulation bag 11 through the connecting component 12. Since the insulation bag 11 is hemispherical, the water storage space inside the insulation bag 11 is small. The water and air in the water storage chamber can be completely extracted through the extraction component 13. The remaining water can flow along the insulation bag 11 to the extraction component 13 and the connecting component 12 for accumulation, making the inside of the insulation bag 11 cleaner. At the same time, the volume of the insulation bag 11 is reduced after the water and air are extracted, leaving more gaps in the installation space.

[0035] Example 2

[0036] Reference Figure 1 - Figure 2 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the material of the funnel 122 is increased to make the funnel 122 flexible, which can install the extraction component 13 and improve the safety of the user.

[0037] Preferably, the connecting component 12 includes a water pipe 121 disposed on the insulation bag 11 and connected to the water storage tank, and a funnel 122 disposed at the end of the water pipe 121 away from the insulation bag 11. The water pipe 121 connects the water storage tank and the funnel 122. The funnel 122 facilitates the increase of the water inlet area, allowing for rapid water injection into the insulation bag 11. At the same time, the funnel 122 can collect residual water inside the insulation bag 11 when draining water, making it easier to clean after disassembly.

[0038] Furthermore, the funnel 122 is made of silicone. The use of silicone makes the funnel 122 flexible, allowing it to be bent. When the insulation unit 1 is installed inside the helmet, the flexible funnel 122 allows the position of the extraction component 13 to change, enabling the extraction component 13 to be stored away. This prevents the extraction component 13 from being located near the user's ear or other positions, thus avoiding obstruction of the user's vision or contact with the user's body, which could create safety hazards later on, thereby improving the safety of the helmet.

[0039] Furthermore, the extraction assembly 13 includes a fixed cylinder 131 detachably disposed on the side of the funnel 122 away from the water pipe 121, and a pull rod 132 slidably disposed within the fixed cylinder 131 and extending out of the fixed cylinder 131 away from the end face of the funnel 122. A handle 14 is provided at the end of the pull rod 132 extending out of the fixed cylinder 131. An external threaded groove is provided at the end of the fixed cylinder 131 away from the pull rod 132, and an internal threaded groove on the funnel 122 engages with the external threaded groove. The engagement of the internal and external threaded grooves enables the extraction assembly 13 to be installed. When injecting liquid into the insulation bag 11, the extraction assembly 13 is removed, and liquid is injected into the insulation bag 11 through the funnel 122 and the water pipe 121.

[0040] During use: by pulling the handle 14, the pull rod 132 slides inside the fixed cylinder 131, completely extracting the air and residual moisture from the insulated bag 11. The residual moisture gathers in the funnel 122. Since the funnel 122 is flexible, it can be bent to limit and fix the extraction component 13, preventing it from poking the user and causing safety hazards.

[0041] Example 3

[0042] Reference Figure 1 - Figure 4This is the third embodiment of the present invention. This embodiment further provides a double-layer safety helmet based on intelligent temperature control, including the heat insulation layer in the above embodiment, and also including a safety helmet body unit 2. The safety helmet body unit 2 includes an outer shell 21, an inner shell 22 located inside the outer shell 21, and a connecting ring plate 23 disposed on the inner side of the outer shell 21 and connected to the outer side of the inner shell 22. An installation gap is left between the outer shell 21 and the inner shell 22 for installing a heat insulation bag 11. A water pipe 121 passes through the connecting ring plate 23. The heat-insulating bag 11 is installed on the inner side of the outer shell 21. After being filled with liquid, the heat-insulating bag 11 expands and presses against the outer circumference of the inner shell 22, thereby transferring the heat of the heat-insulating bag 11 to the user's head through the inner shell 22 to keep the user's head warm. In summer, the liquid in the heat-insulating bag 11 is drained through the connecting component 12, and then the extraction component 13 is installed on the connecting component 12. The extraction component 13 evacuates the inside of the heat-insulating bag 11. At this time, the heat-insulating bag 11 on the side away from the inner wall of the outer shell 21 contracts and presses against the inner wall of the outer shell 21, creating a gap between the inner wall of the outer shell 21 and the inner shell 22. This allows the fan unit 3 to blow flowing air into the gap, ensuring ventilation for the user's head and enabling cooling. The inner wall of the inner shell 22 is provided with an insulating layer.

[0043] Fan unit 3 is disposed on the outer side of housing 21. Fan unit 3 includes power supply 31 disposed outside housing 21, sensor 332 disposed outside housing 21, and fan 333 disposed outside housing 21. Power supply 31 continuously supplies power to sensor 332 and fan 333.

[0044] Preferably, the heat-insulating bag 11 contains a heating wire 111, which is connected to the fan unit 3. The sensor 332 includes a temperature sensor, a humidity sensor, and a controller. The temperature sensor detects the internal temperature of the outer casing 21. When the heating wire 111 heats up and the internal temperature of the outer casing 21 reaches a comfortable level, the controller cuts off the power to the heating wire 111 to prevent continuous heating from burning the user's scalp. In summer, the controller can also activate the fan 333 to ventilate and cool the user's head based on the internal temperature of the outer casing 21. Simultaneously, the humidity sensor can also directly activate the fan 333 to cool the user's head when the user's head is sweating in summer.

[0045] Furthermore, the insulation bag 11 is provided with a through hole 112. The through hole 112 does not affect the sealing of the insulation bag 11 itself. The through hole 112 is located at the air outlet of the fan unit 3 and will not block the fan 333 from blowing air into the outer casing 21.

[0046] Furthermore, the outer casing 21 includes a housing 211 and a limiting plate 212 disposed on the outer peripheral surface of the housing 211. The limiting plate 212 is an L-shaped plate. One end of the L-shaped plate is connected to the outer peripheral surface of the housing 211, and the other end of the L-shaped plate faces downward, for limiting and fixing the extraction assembly 13.

[0047] In particular, the limiting plate 212 is provided with a limiting hole 2121, and the limiting plate 212 is provided with an opening 2122 communicating with the limiting hole 2121. The opening 2122 is located directly below the limiting hole 2121, which facilitates the rotation of the extraction component 13 by bending the funnel 122, so that the extraction component 13 can be engaged and locked in the limiting hole 2121, thereby limiting and fixing the extraction component 13 and improving safety.

[0048] Furthermore, the inner shell 22 is provided with multiple ventilation holes 221. By providing multiple ventilation holes 221, the airflow effect on the user's head can be improved during ventilation, making it easier to blow air directly onto the user's head.

[0049] During use: By clamping the fixing cylinder 131 into the limiting hole 2121, the extraction component 13 is limited and fixed. Then, the fan 133 is started, and the air blows into the installation gap of the heat preservation bag 11 after the air is extracted. Therefore, air can flow in the gap, so that the user's head can be cooled down. It has both heat preservation function and ventilation and cooling effect, improving the practicality of the safety helmet.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
