Description

Technical Field

[0001] This utility model relates to the field of one-way valve technology, and in particular to a one-way valve with adjustable breathability for down jackets. Background Technology

[0002] A check valve is a type of valve that allows fluid to flow freely in one direction while blocking flow in the opposite direction. It is typically used to prevent fluid backflow and protect system equipment from the effects of reverse flow.

[0003] In most conventional down jacket designs, the breathability and moisture-wicking function of down jackets mainly rely on the breathability of the fabric itself. However, the breathability of the fabric is relatively fixed and cannot flexibly adjust the internal and external air circulation according to the wearer's actual needs. It cannot regulate and control the air circulation, so the wearer cannot expel the heat and moisture generated in the body in time or lock in the heat to prevent heat loss.

[0004] To address this, a one-way valve with adjustable breathability for down jackets is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a one-way valve with adjustable breathability for down jackets, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a one-way valve for adjustable breathability in down jackets, wherein the one-way valve is installed on the down jacket and is used for regulating the exhaust of the down jacket; the one-way valve includes a valve seat, in which an insulating plate is fixedly connected, and a highly elastic diaphragm is provided in the insulating plate; the valve seat is provided with a switching assembly for regulating the breathability of the one-way valve, the switching assembly includes a barrier plate disposed in the valve seat, a fixing post is provided in the barrier plate, and a fixing hole is provided in the valve seat.

[0007] Preferably, the valve seat is provided with a placement platform and a support platform, and a highly elastic diaphragm is located on the placement platform and the support platform.

[0008] Preferably, a sealing plate is fixedly connected between the placement platform and the valve seat, and an exhaust port is provided on the sealing plate.

[0009] Preferably, a limiting post is fixedly connected to the sealing plate, and a limiting hole is formed on the highly elastic diaphragm, with the limiting post inserted into the limiting hole.

[0010] Preferably, the valve seat has an arc groove, and the baffle plate is slidably connected in the arc groove, and the fixing hole is located in the arc groove.

[0011] Preferably, a rotating shaft is fixedly connected to the barrier plate, and the rotating shaft is rotatably connected to the sealing plate. A miniature spring is fixedly connected between the fixing post and the barrier plate. The end of the fixing post and the opening of the fixing hole are both arc-shaped.

[0012] Preferably, a baffle is fixedly connected to the top of the valve seat, and the baffle has an air outlet and a rotation port.

[0013] The beneficial effects of this utility model are:

[0014] This invention, through the setting of a switch component, enables down jackets equipped with one-way valves to release heat and moisture when worn for exercise. The body's movement greatly enhances the airflow within the down jacket, and the compressed air compresses the highly elastic diaphragm, causing it to deform. This allows heat and moisture to escape upwards through the highly elastic diaphragm and outwards through the exhaust port, achieving timely heat dissipation and moisture removal. When exercise stops, the highly elastic diaphragm promptly returns to its original position, preventing heat from escaping and effectively locking in body temperature.

[0015] Meanwhile, when wearing a down jacket for light exercise that does not require heat dissipation, such as jogging, the baffle plate can be rotated and slid in the arc groove to seal the exhaust port. Even during light exercise, the movement of the body and arms can compress the heat in the down jacket, causing the high-elasticity membrane to deform and lift. The hot air cannot escape through the exhaust port after passing through the high-elasticity membrane, thus locking in the hot air and keeping the body warm. Rotating in the opposite direction will keep the exhaust port open and allow for the expulsion of air and moisture. The entire device makes heat and moisture dissipation more flexible and controllable, and can adjust the airflow in a timely manner. Attached Figure Description

[0027] like Figures 1 to 7As shown in the figure, a specific embodiment of this utility model provides a one-way valve with adjustable breathability for down jackets. One-way valve 1 is installed on down jacket 2, and down jacket 2 is connected to one-way valve 1. One-way valve 1 is used for regulating the exhaust of down jacket 2. The connection method between one-way valve 1 and down jacket 2 is existing technology and will not be described in detail. One-way valve 1 includes valve seat 3, in which an insulating plate 4 is fixedly connected. The insulating plate 4 is provided with a high-elasticity diaphragm 5. The valve seat 3 is provided with a switch assembly for regulating the breathability of one-way valve 1. One-way valve 1 is installed on down jacket 2, and by setting the switch assembly, the air circulation can be adjusted according to the actual needs of the wearer, so as to timely expel the heat and moisture generated in the body, and at the same time, to lock in the temperature and prevent heat loss. The switch assembly includes an insulating plate 6 provided in the valve seat 3, in which a fixing post 7 is provided, and in which the valve seat 3 is provided with a fixing hole 8.

[0028] like Figures 1 to 7 As shown, specifically, the valve seat 3 is provided with a placement platform 9 and a support platform 10, and a high-elasticity diaphragm 5 is located on the placement platform 9 and the support platform 10. A sealing plate 11 is fixedly connected between the placement platform 9 and the valve seat 3. An exhaust port 12 is provided on the sealing plate 11, and a limiting post 13 is fixedly connected to the sealing plate 11. A limiting hole 14 is provided on the high-elasticity diaphragm 5, and the limiting post 13 is inserted into the limiting hole 14. A baffle 18 is fixedly connected to the top of the valve seat 3, and an air outlet 19 and a rotation port 20 are provided on the baffle 18. When the down jacket 2 is worn and during exercise, the body generates a lot of heat and moisture. At this time, due to the movement of the arms, the airflow in the down jacket 2 is greatly enhanced, which compresses the air, allowing the heat and moisture to enter the valve seat 3. The compressed heat and moisture compress the high-elasticity diaphragm 5 in the valve seat 3, thereby causing the high-elasticity diaphragm 5 to deform. At the same time, due to the high elasticity... With the cooperation of the limiting post 13 and the limiting hole 14, one end of the diaphragm 5 causes the other end of the high-elasticity diaphragm 5 to be lifted upward under the deformation. At this time, the heat and moisture at the bottom of the high-elasticity diaphragm 5 can flow outward through the deformation and lift of the high-elasticity diaphragm 5 and enter between the sealing plate 11 and the baffle 18 through the exhaust port 12. Then, it is discharged outward through the air outlet 19 and the rotating port 20 on the baffle 18, thereby expelling the heat and moisture from the body. At the same time, when there is no movement, there is no movement between the arms, resulting in less airflow in the down jacket 2. After the high-elasticity diaphragm 5 is restored from its initial deformation, the pressure of the air heat prevents the high-elasticity diaphragm 5 from deforming again and cannot be lifted upward. The heat cannot be discharged upward under the obstruction of the high-elasticity diaphragm 5 and the insulating plate 4, thus preventing the air heat generated in the body from being discharged from the down jacket 2 and locking the heat in the body in time.

[0029] like Figures 1 to 7As shown, specifically, the valve seat 3 has an arc groove 15, and the baffle plate 6 is slidably connected in the arc groove 15. The fixing hole 8 is located in the arc groove 15. A rotating shaft 16 is fixedly connected to the baffle plate 6, and the rotating shaft 16 is rotatably connected to the sealing plate 11. A miniature spring 17 is fixedly connected between the fixing post 7 and the baffle plate 6. The end of the fixing post 7 and the opening of the fixing hole 8 are both arc-shaped. When the wearer is doing light exercise such as jogging, we do not need to expel the heat generated in the body. At this time, the finger passes through the rotating port 20 to rotate the valve seat 3. The rotating shaft 16 drives the baffle plate 6 to slide in the arc groove 15, causing the rotating baffle plate 6 to slide to the top of the exhaust port 12. When the baffle plate 6 slides to the top of the exhaust port 12, the fixing post 7 in the baffle plate 6 is located at the fixing hole 8. Under the force of the micro spring 17, the fixing post 7 moves into the fixing hole 8 for limiting and locking, thus giving the baffle plate 6 a certain stability at the top of the exhaust port 12 and preventing the baffle plate 6 from shifting during slight movement. The baffle plate 6 at the top of the exhaust port 12 can control the exhaust port 12. In this sealed environment, even during light exercise, the movement of the body and arms causes the air heat inside the down jacket 2 to be compressed, causing the high-elasticity diaphragm 5 to deform and lift. The hot air passing through the high-elasticity diaphragm 5 cannot escape through the exhaust port 12, thus locking in the hot air and keeping the body warm. Conversely, if the body feels uncomfortable due to overheating, rotating the rotating shaft 16 again causes the barrier plate 6 to slide again. Because the end of the fixing post 7 and the opening of the fixing hole 8 are both arc-shaped, the barrier plate 6 is subjected to rotational force, causing the fixing post 7 to... When the baffle plate 6 is squeezed and detached from the fixing hole 8, it can slide in the arc groove 15. The sliding of the baffle plate 6 means that the baffle plate 6 no longer forms a sealing effect on the exhaust port 12. Therefore, the hot air in the body can be discharged outward through the exhaust port 12 after passing through the deformed high elastic membrane 5. The fixing post 7, which is detached from the fixing hole 8, will be subjected to the reaction force of the micro spring 17, which will squeeze the inner wall of the arc groove 15. The squeeze will give the baffle plate 6 a certain stability in the arc groove 15, thereby preventing it from moving at will.
