Description

Technical Field

[0001] This utility model relates to the field of connection interfaces, and more particularly to a quick connection interface component for a liquid cooling circulating cooling system. Background Technology

[0002] People working in high-temperature environments, such as delivery drivers, firefighters, or factory workers, typically need to wear recirculating cooling suits to stay comfortable. These suits have an internal water circulation system that uses cold water to remove body heat. The cooling source (such as a cooling water tank) is usually placed on nearby stationary equipment or vehicles, such as electric motorcycles.

[0003] Currently, traditional threaded interfaces are commonly used for connecting pipes. These interfaces require multiple tightening rotations during connection, making the process cumbersome and time-consuming. This is extremely inconvenient in situations requiring frequent plugging and unplugging (such as reconnecting after outdoor workers take a break). More importantly, threaded interfaces cannot automatically cut off the power source of the cooling system (such as a water pump) upon disconnection, nor can they automatically seal the water circuit, posing risks of liquid leakage and equipment idling. Both safety and convenience need improvement. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a novel interface component capable of achieving rapid and automatic alignment, and automatically controlling the water flow and system power source during connection / disconnection.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a quick-connect interface assembly for a circulating liquid cooling system, comprising an A-end interface connected to a cold source device and a B-end interface connected to cooling clothing; the A-end interface and the B-end interface are respectively provided with mutually attractive magnetic elements for quick positioning and adsorption during docking; the A-end interface is provided with a fluid pump switch, which is triggered by the B-end interface to conduct the circuit of the fluid pump when the A-end interface docks with the B-end interface; when the two are separated, the fluid pump switch is reset and the circuit is cut off.

[0006] Furthermore, the magnetic attraction element is embedded in the mating surfaces of the A-end interface and the B-end interface, respectively.

[0007] Furthermore, both the A-end interface and the B-end interface have through holes in the center of their magnetic elements, and the through holes of the magnetic elements constitute part of the water passage of their respective interfaces; when the A-end interface is connected to the B-end interface, the pushing mechanism of the B-end interface passes through the through holes of the magnetic elements to open the check valve of the A-end interface.

[0008] Furthermore, the fluid pump switch is a mechanical limit switch, and the actuator of the mechanical limit switch is located inside the mating surface of the A-end interface; when the A-end interface and the B-end interface are mated due to magnetic attraction, the mating surface of the B-end interface presses against the actuator to trigger the mechanical limit switch.

[0009] Furthermore, the A-end interface has a receiving groove for installing the fluid pump switch, and the receiving groove has a channel for the line to pass through.

[0010] Furthermore, the A-end interface is provided with a first inlet end and a first outlet end, and both the first inlet end and the first outlet end are provided with normally closed check valves; the B-end interface is provided with a push mechanism corresponding to the check valve; when the interfaces are connected, the push mechanism is activated to open the check valve, so that the water paths of both parties are connected; when the interfaces are separated, the check valve automatically closes to seal the water path.

[0011] Furthermore, the check valve includes a valve core and an elastic reset element. In its natural state, the valve core closes the water passage under the action of elastic force. When subjected to the pushing mechanism, the valve core moves against the elastic force to open the water passage.

[0012] Furthermore, the water passage of the B-end interface is equipped with a one-way valve plate, which closes the water passage under natural conditions and opens under the action of water flow pressure.

[0013] Furthermore, a sealing structure is provided between the mating surfaces of the A-end interface and the B-end interface.

[0014] Furthermore, the sealing structure includes a sealing gasket fitted on the mating surface of the A-end interface, and a protruding ridge disposed on the mating surface of the B-end interface for squeezing the sealing gasket during mating.

[0015] The beneficial effects of this invention are as follows: The magnetic element enables rapid alignment and magnetic connection between the A-end and B-end interfaces. Users only need to bring the interfaces close together to achieve accurate docking under magnetic guidance, greatly improving ease of use. The linkage switch mechanism and valve assembly on the interface enable automatic on / off control of the fluid pump. The system automatically starts when the interfaces are docked and immediately cuts off power and closes the water circuit when the interfaces are separated. This not only improves the automation level of operation but also fundamentally eliminates the risk of pump dry running and liquid leakage after interface separation, significantly improving the system's safety and reliability. This design cleverly integrates mechanical connection and electrical control, achieving a balance between convenience and safety with a simple and reliable structure. Attached Figure Description

Detailed Implementation

[0023] Please see Figure 1-6 As shown, the present invention will be described in detail through the following preferred embodiments, and these descriptions should be taken in conjunction with the accompanying drawings. Figure 1 And read. However, this invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concept of this invention to those skilled in the art.

[0024] See Figures 1 to 6 This invention provides a quick-connect interface assembly for a circulating liquid cooling system. The assembly mainly includes an A-end interface 100 and a B-end interface 200. The A-end interface 100 is connected to a cooling source device (such as a cooling unit with a built-in water pump and water tank) via a pipe; the B-end interface 200 is connected to the user's circulating cooling clothing via a flexible hose. Its core function is to achieve rapid, reliable, and automatic connection and disconnection of the water and electrical circuits between the clothing and the cooling source.

[0025] The core of the A-end interface 100 is a first outer shell 101 made of engineering plastic (such as POM polyoxymethylene) through injection molding. Inside the first outer shell 101 are two isolated independent flow channels, defined as a first water inlet A1 and a first water outlet A2. The first water inlet A1 receives cold water from a cooling source device, and the first water outlet A2 returns heated coolant to the cooling source device. Two strongly magnetic first magnets 130 (e.g., neodymium iron boron magnets) are symmetrically embedded in the top mating surface (i.e., the upward-facing plane) of the first outer shell 101. The first magnets 130 are completely encased in the plastic material. The core function of the first magnets 130 is to work in conjunction with the corresponding magnets on the B-end interface 200 to generate a strong magnetic attraction force, enabling rapid automatic alignment (blind insertion) and firm adsorption retention during docking.

[0026] Each of the first magnets 130 has an A-end magnet through hole 131 machined at its center along its axial direction (e.g., ...). Figure 4 (As shown) 1. The A-end magnet through hole 131 is funnel-shaped, with its large-diameter end facing upwards (towards the mating surface) and its small-diameter end leading to the internal flow channel of the first outer shell 101. The A-end magnet through hole 131 of the first magnet 130 directly constitutes part of the water channel of the A-end interface 100.

[0027] At the ports of the first inlet A1 and the first outlet A2, specifically below the through hole 131 of the first magnet 130 at end A, a normally closed check valve 120 is provided. The specific structure of the check valve 120 is as follows: the inner wall of the flow channel inside the first housing 101 is designed with varying orifice diameters, forming a small-diameter section 125 and a large-diameter section 126. A columnar valve core 121 (with a sealing head at its front end resembling a "nail head") is placed in this flow channel. A spring 123 continuously acts on the rear end of the valve core 121, providing a spring force to return it to the flow channel opening. In its natural state (i.e., the interface is separated), the spring force of the spring 123 pushes the valve core 121, causing its sealing head to press tightly against the port of the small-diameter section 125, forming a sealing surface, thereby completely sealing the flow channel.

[0028] When the interfaces are connected, the pusher 220 of the B-end interface 200 extends into the magnet through-hole 131 of the A-end interface 100 and presses against the sealing head at the front end of the valve core 121. The continuous magnetic force pushes the pusher 220, causing the valve core 121 to move backward (i.e., into the flow channel) against the elastic force of the spring 123. When the sealing head of the valve core 121 is pushed away from the small-diameter section 125 and enters the rear large-diameter section 126, an annular gap is formed between them because the diameter of the sealing head is smaller than the inner diameter of the large-diameter section 126. Coolant can flow through this gap, thus achieving water circuit continuity. When the interfaces are separated, the pusher 220 retracts, and the valve core 121 immediately returns to its original position under the action of the spring 123. Its sealing head re-embeds and seals the port of the small-diameter section 125, quickly cutting off the water circuit.

[0029] Inside the first housing 101, a receiving groove 150 is also provided. A mechanical normally open contact limit switch 210 (as a fluid pump switch) is fixedly installed in the receiving groove 150 (e.g., Figure 5 (As shown). The button (i.e., the actuating component) of the limit switch 210 is positioned facing the inner side of the top mating surface of the A-end interface 100 and slightly protrudes from the opening of the receiving groove 150. A wire hole 151 is provided at the bottom of the receiving groove 150 for the electrical lead of the limit switch 210 to pass through and connect to the drive circuit of the water pump in the cold source device. The core function of this limit switch 210 is as a circuit control switch for the fluid pump. It automatically controls the start and stop of the water pump by detecting the physical connection status of the A and B end interfaces, realizing a safe control logic of power on when connected and power off when disconnected.

[0030] On the top mating surface of the first housing 101, a ring of sealing silicone gaskets 160 is also fixed by adhesive. Figure 2 and Figure 4 (As shown). The core function of the sealing silicone gasket 160 is to cooperate with the protruding rib of the B-end interface 200 to form a reliable planar seal on the mating surface, preventing coolant leakage at the interface mating point.

[0031] The specific structure of the B-end interface 200: The B-end interface 200 has a second outer shell 201 also made of engineering plastic. A second magnet 230 (functioning the same as the first magnet 130, achieving magnetic alignment) is embedded in its bottom mating surface (i.e., the downward-facing plane). The second magnet 230 also has a funnel-shaped B-end magnet through-hole 231 at its center, with its larger diameter end facing downwards (towards the mating surface). This B-end magnet through-hole 231 communicates with the water passages of the second water outlet B2 (connecting to the garment's water inlet pipe) and the second water inlet B1 (connecting to the garment's water return pipe) of the B-end interface 200.

[0032] On the bottom mating surface of the second housing 201, corresponding to the position of the check valve 120 at the A-end interface 100, two downwardly protruding push-up supports 220 are integrally formed, serving as a push-up mechanism. The diameter of the push-up support 220 is slightly smaller than the diameter of the small-diameter end of the A-end magnet through hole 131 of the first magnet 130 at the A-end, and its height is designed to effectively push open the check valve 120 at the A-end during mating. The core function of this push-up mechanism 220 is to act as a trigger rod for the A-end check valve 120. During the mating process, it passes through the through hole of both magnets, physically pushing open the valve core 121 in the A-end check valve 120, thereby opening the cooling water circulation path.

[0033] Inside the water passage of the B-end interface 200, specifically in the flow channel of the second inlet B1, a one-way valve plate 250 is also provided (e.g., Figure 3 and Figure 6 (As shown). The one-way valve plate 250 is made of elastic silicone and has a "I" or "+" slit in its center. Under natural conditions, without external force, the slit remains closed due to the elasticity of the material, sealing the water passage. The core function of the one-way valve plate 250 is as an auxiliary seal for the water passage at end B. It automatically closes when there is no water pressure (i.e., after the interface is disconnected), forming a double seal with the check valve at end A, especially to prevent residual liquid in the garment side pipeline from leaking after disconnection.

[0034] On the bottom mating surface of the second outer shell 201, a ring-shaped protruding rib 240 is also designed to surround the second magnet 230 and the push-up support 220 (e.g., Figure 2 and Figure 3 (As shown). The core function of this bone position 240 is to work in conjunction with the sealing gasket at end A to provide precise clamping force during docking, ensuring that the sealing gasket deforms appropriately to achieve the best sealing effect.

[0035] Working process and principle

[0036] When the user aligns the B-end interface 200 downwards with the upward-facing A-end interface 100 and brings them close together, a strong magnetic attraction is generated between the first magnet 130 and the second magnet 230 of both interfaces, automatically guiding the interfaces to precise alignment and secure adhesion. During this process, the annular protrusion 240 at the bottom of the B-end interface 200 is initially pressed into the sealing silicone gasket 160 at the top of the A-end interface 100, forming an initial sealing contact.

[0037] Waterway connection: Under the continuous action of magnetic attraction, the pusher support 220 of the B-end interface 200 passes through the B-end magnet through hole 231 and the A-end magnet through hole 131 in sequence, and finally precisely presses against the sealing head of the valve core 121 of the A-end check valve 120. The pushing force overcomes the elastic force of the spring 123, pushing the valve core 121 to move backward (downward), so that its sealing head moves from the small diameter section 125 of the flow channel to the large diameter section 126. Since the diameter of the sealing head is smaller than the inner diameter of the large diameter section 126, an annular gap is formed, and the waterways of the A-end and B-end are connected through the through hole in the center of the magnet.

[0038] The circuit is finally turned on: When the interface is fully connected and the magnetic attraction is at its maximum, the bottom mating surface of the B-end interface 200 presses against the limit switch 210 button on the A-end interface 100, causing its normally open internal contact to close, thereby turning on the power supply circuit of the water pump, and the water pump starts to run, driving the coolant to circulate throughout the system.

[0039] Instantaneous circuit cutoff: When the B-end interface 200 is lifted upwards, at the moment of separation, the mating surface of the B-end interface 200 no longer presses against the limit switch 210 button. The button quickly springs up under the action of the internal spring, the contacts disconnect, and the water pump circuit is immediately cut off, preventing the water pump from running dry. Almost simultaneously with the circuit cutoff, the push-up support 220 of the B-end exits from the through hole of the A-end. The valve core 121 of the check valve 120 of the A-end loses its pushing force and quickly resets upwards under the action of the spring 123. Its sealing head is then tightly pressed back into the port of the small-diameter section 125, instantly sealing the water passage at the A-end. At the same time, due to the disappearance of water pressure, the one-way valve plate 250 inside the B-end interface 200 automatically closes its slit under its own elasticity, reliably sealing the water passage at the B-end and ensuring no leakage on the garment side.

[0040] It should be noted that the above embodiments are merely preferred embodiments for realizing the concept of this utility model and are not intended to limit the utility model. Within the essential spirit of this utility model, those skilled in the art can conceive of various alternative solutions. For example, the triggering mechanism is not limited to a mechanical combination and can be completely replaced by a non-contact sensing solution, such as setting a Hall sensor at the A-end interface 100 and setting a magnet at the corresponding position at the B-end interface 200, using the change in magnetic flux to trigger the switching signal. Similarly, the check valve 120 can also adopt other forms of one-way valve structures such as a flap valve or umbrella valve. The number, shape, and arrangement of magnets can be adjusted according to the required adsorption force and interface shape. All equivalent substitutions or obvious modifications based on the core technical concept of this utility model and conceivable by conventional knowledge in the art should be considered to be included within the protection scope of this utility model. The above expanded version adds a large number of technical details, such as the specific working mechanism of materials and components, the decomposition of the workflow, and alternative solutions, making the description more complete and in-depth, and meeting the requirements of full disclosure in the patent specification.
