Description

A type of fast-cooling air-venting vest Technical Field

[0001] This invention relates to the field of cooling clothing technology, specifically a fast-cooling, air-ventilated vest. Background Technology

[0002] An airflow vest is a specially designed vest featuring an internal ventilation system to promote airflow and help keep the body cool. These vests are typically used in high-temperature, high-humidity environments or where high breathability is required, such as outdoor sports, construction sites, and tropical regions.

[0003] The ventilation system of an airflow vest can include ventilation ducts, vents, fans, or other ventilation devices. These designs allow outside air to flow through the inside of the vest, come into contact with the wearer's body, and carry away body heat and sweat, thus providing a cool and comfortable wearing experience.

[0004] For example, the work clothes for mining workers provided by patent number CN206852078U disclose the following technical solution: It includes a vest body, which comprises a front chest surface and a back surface. A cooling and humidifying device is provided on the vest body. This cooling and humidifying device includes a water storage bag and a water storage layer disposed on the inner side of the front chest surface and the back surface. The water storage bag is located above the water storage layer, and a water outlet is provided at the lower end of the water storage bag. The water outlet is connected to one end of a conduit, and the other end of the conduit is provided with an overflow hole. Water from the water storage bag is poured onto the water storage layer through the overflow hole. A blower is also provided on the vest body, which is connected to an air duct. An exhaust section is provided on the air duct, which is in the shape of a mesh pipe and located outside the water storage layer. Several exhaust holes are opened on the exhaust section, and the exhaust holes are opposite to the water storage layer.

[0005] However, the above technical solutions have the following drawbacks: the battery power consumption is large during the cooling process when using a fan; and the existing method of using a fan for heat dissipation introduces external airflow into the vest through ventilation pipes and exhausts it through the vents, causing the garment to expand, creating resistance to movement and resulting in low comfort. Furthermore, as the air pressure decreases, the ventilation effect declines, causing discomfort after prolonged wear. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a fast-cooling air-venting vest.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a quick-cooling, air-ventilated vest, comprising a back component and a left chest piece and a right chest piece respectively connected to the back component.

[0008] The back component, along with the left and right chest X-rays, consists of a sealed interlayer formed by two barrier layers.

[0009] The back component is equipped with a fan for airflow to flow into the interlayer of the back component, and the interlayer is equipped with an airflow guide channel for air guidance and dispersion.

[0010] The back component has several air outlets with connecting airflow channels for directional and rapid cooling and heat exchange in the area covered by the human body.

[0011] The air introduced by the fan flows into the interlayer, passes through the air guide channel, and then flows out from the air outlet.

[0012] Furthermore, the air vents are located in the back neckline area of ​​the back component and the back sleeve loops on both sides of the back component, and the air vents are directed outwards towards the back component.

[0013] Furthermore, the outer side of the back panel features a backpack ventilation area.

[0014] Furthermore, the airflow channel includes: a guide plate, which is installed in the interlayer and connected to the fan, forming an air storage area with the backpack blower area. Several ventilation openings are provided on the guide plate, and the ventilation openings are connected to the air outlet.

[0015] As a preferred embodiment of this application, the air outlet channel is further provided with: an air outlet plate, on which a corresponding air outlet is opened on the side facing the air outlet; a number of grid-shaped air outlets connected to the air outlet plate are provided on the air outlet plate; the air outlet plate is arranged in a honeycomb pattern and corresponds to the air outlet provided on the air outlet plate.

[0016] Furthermore, the side wings of the back component are connected to the corresponding left and right chest pieces via adjustable pull cords, and the left and right chest pieces are connected to each other via adjustable pull cords.

[0017] Furthermore, a portable backup power supply that can be detachably connected to the wind turbine is also installed.

[0018] Furthermore, the backpack's ventilation area features a storage compartment made of barrier material.

[0019] This application also includes another embodiment, which includes a circulating cold conduction assembly arranged in a serpentine pattern along the back component, left chest X-ray, and right chest X-ray to form a closed loop.

[0020] Furthermore, the circulating cold conduction unit is located inside the barrier layer and is used to supply cold air to the air in the air outlet channel.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The sealed design of the back component in this application helps reduce the direct penetration of external air into the vest. With a separate air vent driven by a fan, it achieves good breathability and pays more attention to the balance between sealing and breathability, accelerating the air circulation inside the vest, reducing stuffiness and improving wearing comfort. Due to its practicality and portability, this vest is very suitable for wearing in a variety of occasions such as outdoor work, sports and fitness, and high-temperature workshops.

Detailed Implementation

[0034] 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.

[0035] The existing air-conditioned clothing sold uses a fan installed on the windproof fabric layer on the outer surface and a mesh fabric lining. The fan brings outside air into the clothing, thereby creating airflow to cool the body. As the operation of the fan creates airflow inside the clothing, it initially feels cool. However, as the fan continuously fills the clothing with air, the air pressure inside the clothing gradually equalizes with the outside air pressure, making it difficult for the airflow to circulate. This causes the clothing to expand and restrict the wearer's movement.

[0036] Therefore, this application provides a quick-cooling, air-ventilated vest, as shown in Figures 1-5, including a back component 1 and a left chest piece 2 and a right chest piece 3 respectively connected to the back component 1.

[0037] The back component 1 is constructed from two barrier layers 4 to form a sealed interlayer, and the back component 1 forms an independent sealed chamber;

[0038] Alternatively, the back component 1, the left chest piece 2, and the right chest piece 3 may all be constructed from two barrier layers 4 to form a sealed interlayer that is interconnected;

[0039] The barrier layer 4 must at least meet the requirement of being airtight in actual use. Preferred materials include: polyester, nylon, polyester and other chemical fiber fabrics, as well as PVC and polyethylene and other plastic fabrics. These fabrics generally have poor air permeability and high density to ensure that air and water vapor cannot pass through. Alternatively, sturdy PU-coated nylon can be used, which has strong wind and rain resistance and is also not conducive to gas permeability.

[0040] This application can implement the following technical solutions based on any one of the above technical solutions, specifically including:

[0041] A fan 5 is provided on the back component 1 for airflow to flow into the interlayer of the back component 1, and an air outlet channel 6 for air guidance and dispersion is provided in the interlayer.

[0042] The back component 1 is provided with a series of air outlets 11 through a connecting air outlet channel 6 to ensure directional and rapid heat exchange between the vest and the human body coverage area. The human body coverage area is defined as the contact area between the back component 1 and the human body. The air introduced by the fan 5 flows into the interlayer, passes through the connecting air outlet channel 6, and then flows out from the air outlets 11. The air outlets 11 are arranged in a straight single-lip bag, a V-shape, or a round hole, or other conventional shapes. The size of the opening can be changed by the airflow.

[0043] As shown in Figure 3, in this embodiment, the fan 5 can be either an air pump or a fan, and it is powered by an external power supply. When there is only one fan 5, the air pump is preferred. The air pump consumes 5V to ensure that there is enough air pressure to blow air out from the air outlet 11.

[0044] Alternatively, as shown in Figure 1, when there are two or more fans 5, but based on cost accounting, two are preferred. The fans 5 are preferably fans, and their energy consumption is 5V. In the above embodiment, the fans 5 are driven by an external power source, that is, the air pump or the fan is driven by an external lithium battery.

[0045] The installation position of the fan 5 is also very important. In order to ensure uniform airflow and safe operation, when there is one fan 5, it is set in the center between the air outlets 11. When there are two fans 5, the airflow is too strong. It is preferable to set them at the bottom ends of the back part 1 to ensure effective airflow and a close fit to the clothes.

[0046] The diameter of the air outlet 11 is between 0.1cm and 15cm.

[0047] It should be understood that the vest applied for in this application achieves cooling by the following principle: when the human body is heated, it produces sweat. At this time, the airflow carries away the moisture in the air, and the sweat evaporates on the human body, thereby reducing the humidity of the human body and carrying away heat, so as to reduce the heat of the human body wearing clothes and achieve the cooling effect. If the human body is not sweating, the airflow drives the airflow of the human body to fill the vest with new air, thereby ensuring air circulation. This application mainly achieves this by setting an air outlet 11 on the surface of the vest. The size of the air outlet 11 is proportional to the operating power of the fan 5, and the number of air outlets 11 is proportional to the air delivery power of the fan 5, so as to ensure the effective air delivery of the vest while avoiding excessive expansion of the vest involved in this application. The air outlet 11 is set towards the end wall of the vest. After experimentation, the expansion coefficient of the vest of this application during the blowing operation is between 1 and 1.5 times, which is much smaller than the deformation of existing air-conditioned clothing after blowing expansion.

[0048] That is, the size of the air outlet 11 is the main factor affecting the air circulation efficiency. Therefore, the design of the air outlet 11 must ensure that a pressure difference can be maintained inside the vest. Since the temperature inside the vest also affects the airflow, specifically, when the heat is high, the air density will be low, while the air density will be high in areas with relatively low heat. The airflow will flow from areas with high density to areas with low density, that is, the heat flow moves towards the air outlet. If the density difference is large, the airflow will be large, that is, the wind speed will be high. Therefore, the diameter of the air outlet 11 needs to be limited.

[0049] When air passes through a narrow area, the resistance it encounters decreases, resulting in a decrease in pressure. This pressure difference causes the air to flow out slowly, i.e., the wind speed decreases. During the experiment, it was found that although excessive wind speed, i.e. a strong blowing sensation, can cool quickly, it can easily cause discomfort to the human body and uneven temperature between the vest and the human body. Therefore, the design of the air outlet 11 must ensure that a pressure difference is maintained inside the vest. Therefore, in this embodiment, the number of air outlets 11 is between 1 and 10, with 4 air outlets 11 preferably located under the armpits and 3 air outlets 11 located at the back of the neck.

[0050] In this embodiment, the design of the air outlet also includes: the air outlet 11 is located on the back piece (back) of the vest, the collar (also known as the collar of the back shoulder, located at the top of the back piece 1), the shoulder (specifically the connection between the back piece 1 and the left chest piece 2 and the right chest piece 3 respectively), and the armpit (specifically the top of the side seam bending area of ​​the back piece 1). The setting of the air outlet 11 can effectively cool the human body while making it easier to bring the air out of the vest to avoid the vest from expanding excessively. Example 2:

[0051] In the application, the appropriate size of the air outlet 11 and the corresponding wind speed are determined based on factors such as the air delivery distance, airflow organization, and comfort of the air outlet channel 6. That is, when a person is sitting still, in an office, residence, or other indoor environment, the wind speed of the air outlet 11 usually needs to be limited to a low level of 0.3m / s-5m / s to achieve effective heat dissipation while maintaining comfort. Therefore, in this embodiment, the diameter of the air outlet 11 is 3cm, which is the diameter of the ventilation duct. This setting of the air outlet 11 can increase the flow velocity at the ventilation opening 611, so that a certain air pressure difference is generated inside and outside the vest, thereby increasing the airflow velocity near the vest and further improving the ventilation efficiency. While ensuring the vest fits the skin, it can achieve good ventilation effect.

[0052] The air vents 11 are located at the back neckline area of ​​the back component 11 and at the back sleeve loops on both sides of the back component 11. The air vents 11 are directed outwards from the back component 11. This embodiment, as a preferred option, mainly limits the position of the air vents 11 to ensure effective air circulation and effective cooling of the human body. The air vents 11 are directed outwards from the back component 11, which can directly bring air from inside the vest to the outside of the vest. At this time, the airflow at the contact point between the vest and the human body increases, which also drives the surrounding air to flow, accelerating the cooling of the back of the neck and the armpits on both sides of the body, while ensuring the aesthetics of the clothing.

[0053] As shown in Figure 5, in order to temporarily store air and ensure the overall aesthetics of the vest, a backpack air-blowing area 12 is formed on the outer side of the back component 1.

[0054] As shown in Figure 6, the air outlet channel 6 is preferably made of lightweight and flexible materials, such as PVC, AE, or rubber foam tubes, to facilitate movement when the wearer is wearing it. The air outlet channel 6 includes a guide plate 61, which is disposed in the interlayer and communicates with the fan 5, forming an air storage area with the backpack blower area 12. The guide plate 61 has several ventilation openings 611, which are connected to the air outlet 11. Due to the flexibility of the air outlet channel 6, the vest body can also be made entirely of the barrier layer 4, and the air outlet channel 6 can be laid flat in the barrier layer 4.

[0055] The air outlet channel 6 is also provided with an air outlet plate 62, and the air outlet plate 62 has a corresponding air inlet 621 on the side facing the air outlet 11, wherein the number of air inlets 621 corresponds one-to-one with the number of air outlets 11.

[0056] In order to ensure that the air can be effectively dispersed between the barrier layer 4 and the guide plate 61, the guide plate 61 is provided with a number of grid-shaped air ports 621 that are connected to the air outlet plate 62.

[0057] The air outlet plate 62 is arranged in a honeycomb pattern and corresponds to the air outlet 11 provided on the air outlet plate 62. The honeycomb pattern helps to disperse the airflow and reduce the noise generated when the gas flows. It allows the air to form multiple small channels when flowing in the pipe. These channels help to increase the contact area between the air and the pipe wall, promote air flow, and thus improve ventilation efficiency.

[0058] The two side wings of the back component 1 are connected to the corresponding left chest piece 2 and right chest piece 3 sides by adjustable pull cords 7. The left chest piece 2 and right chest piece 3 are connected by the adjustable pull cords 7, which can be connected by Velcro, buttons, buckles, etc.

[0059] As shown in Figure 8, a portable backup power supply 8 is also installed that can be detachably connected to the fan 5. The portable backup power supply 8 and the fan 5 are connected detachably via USB. In addition, pockets are provided on the outer surfaces of the left chest piece 2 and the right chest piece 3 for storage. A storage bag for storing the portable backup power supply 8 is provided on the back part 1 and at the bottom of the backpack blowing area 12.

[0060] As shown in Figures 5 and 7, the backpack's ventilation area 12 has a storage compartment made of the barrier layer 4 material, which is preferably connected to the back component 1 by a zipper.

[0061] As shown in Figures 8 and 9, this application provides a new technical solution, which also includes a circulating cold conduction group 9 arranged in a serpentine pattern along the breathable layers of the back component 1, left chest piece 2, and right chest piece 3 to form a closed loop. The circulating cold conduction group in this application is preferably a water-cooled vest technical solution disclosed in the prior invention patent CN202210060075.3 of this company. Its principle is that after the coolant in the cooling pipe completes heat exchange, it enters the storage cavity and directly contacts the cooling component below through the liquid inlet, so that the coolant cools down quickly and evenly, reduces the temperature difference of the coolant, and improves the cooling effect of the vest. A liquid receiving hopper is set in the storage cavity so that the coolant can flow along the outer wall of the cooling component from the gap, ensuring that the coolant can be fully cooled. Therefore, it will not be described in detail in this application. The purpose is to increase the cooling effect of the human body. For this purpose, the ventilation pipes located at the back and armpits of the vest are arranged in a curved and spiral shape. The design employs an S-shaped bend to adapt to spatial arrangement, change airflow direction, reduce wind speed, avoid energy loss caused by right-angle turns in airflow, optimize airflow distribution, reduce turbulence and noise generation, regulate the dynamic characteristics of airflow, and balance the pressure in the distribution pipes. In actual operation, the coolant storage chamber of the above-mentioned technical solution is placed inside the backpack interlayer.

[0062] In addition, the air outlet 11 provided in this application works with the circulating cooling system 9 to accelerate the circulation of cold air. The main cooling effect is achieved through heat convection and heat conduction, which effectively disperses the cold air.

[0063] To further ensure the effective delivery of cold air and reduce the impact of human body temperature on the cooling pipes in the circulating cold conduction group 9, the circulating cold conduction group 9 is set inside the barrier layer 4 to supply cold air to the air in the air outlet channel 6, further improving the effective dispersion of cold air (since this structure is not limited to any position in the barrier layer 4 and the structure is easy to imagine, it will not be described in detail in the figure, but in this embodiment, it is preferred that the cooling pipes in the circulating cold conduction group 9 be set between the guide plate 61 and the air outlet plate 62).

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention 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 solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
