[0017]

[0023] The following detailed description of the embodiments of the present invention will be given. Examples of the described embodiments are shown in the drawings, in which the same or similar reference numerals throughout indicate the same or similar elements, or elements having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and are intended to explain the present invention only, and should not be construed as limiting the present invention.

[0018] As shown in FIGS. 1 to 25, an embodiment of the present invention provides a heat-exhaust-less portable air conditioner, which includes a housing 10, a condenser 20, an evaporator 80, a water tank 30, and a water guide member 40.

[0019] Housing 10 is the housing of an air conditioner and has a storage cavity 11 provided therein. As shown in Figures 1 to 3, storage cavity 11 has a first duct 12 and a second duct 13. Housing 10 has a first air intake port 121, a second air intake port 131, a first exhaust port 122 and a second exhaust port 132, with first air intake port 121 and first exhaust port 122 both communicating with first duct 12, and second air intake port 131 and second exhaust port 132 both communicating with second duct 13.

[0020] The first duct 12 is mainly used for the heat dissipation process of the condenser 20, and the second duct 13 is mainly used for the cooling process of the evaporator 80, so that the air conditioner can use two independent ducts to control the air flow for the condenser 20 and the air flow for the evaporator 80. The separate design of the first duct 12 and the second duct 13 realizes effective air circulation, avoids thermal interference between the condenser 20 and the evaporator 80, and improves the stability and efficiency of the air conditioner.

[0021] In one possible embodiment, as shown in Figure 3, a partition plate 14 is provided in the housing 10, which divides the storage cavity 11 into two cavities (i.e., a first duct 12 and a second duct 13). The installation of the partition plate 14 makes the first duct 12 and the second duct 13 independent of each other and do not interfere with each other. A first fan 15 is provided in the first duct 12, and a second fan 16 is provided in the second duct 13, which can accelerate the air flow in the first duct 12 and the second duct 13 and improve the efficiency of heat dissipation and cooling. The first fan 15 in the first duct 12 draws in air through the first air intake port 121, passes it through the condenser 20, and then discharges it from the first exhaust port 122. The second fan 16 in the second duct 13 draws in air through the second air intake port 131, passes it through the evaporator 80 for heat exchange, and then discharges it from the second exhaust port 132.

[0022] The condenser 20 is provided in the first duct 12 and includes a first heat exchange element 21, which is a coil of the condenser 20. The superheated gas discharged from the compressor 90 releases heat as it moves forward in the coil, and the refrigerant becomes a subcooled liquid when it reaches the outlet of the coil. The first heat exchange element 21 contains a refrigerant, which is a medium for transferring heat in the air conditioning system and circulates in the air conditioning system, absorbing and releasing heat by changing phases.

[0023] In conventional air conditioning systems, heat dissipation from the condenser 20 is achieved by a fan dissipating heat to the external environment. In the embodiment of the present invention, heat dissipation from the condenser 20 is primarily achieved by heat exchange with the coolant. The temperature of the coolant is lower than the temperature of the refrigerant in the condenser 20, so it can absorb heat more effectively and improve heat dissipation efficiency. The heat exchange between the coolant and the refrigerant in the condenser 20 prevents excess heat from being directly discharged to the external environment, reducing thermal pollution to the surrounding environment.

[0024] The evaporator 80 is provided in the second duct 13, and its role is to absorb heat in the refrigerant to reduce the temperature of the air and achieve a cooling effect. In the second duct 13, the evaporator 80 absorbs heat in the air through heat exchange with the air, thereby reducing the air temperature.

[0025] The water tank 30 is disposed in the receiving cavity 11 and has a water storage cavity 304 for storing a coolant, which may be water, and the temperature of the coolant is lower than the temperature of the refrigerant in the first heat exchange member 21. The role of the water tank 30 is to provide low-temperature coolant to the condenser 20. The temperature of the coolant is lower than the temperature of the refrigerant in the condenser 20, allowing the coolant to absorb heat in the condenser 20 and achieving heat exchange. Preferably, the coolant can be circulated, and the circulating flow of the coolant continuously supplies low-temperature coolant to the condenser 20.

[0026] The water guide member 40 is provided in the first duct 12 and is used to draw the coolant to the first heat exchange member 21, thereby realizing heat exchange between the coolant and the refrigerant. The water guide member 40 may be in various forms, such as a nozzle or vanes 43, which allows the coolant to be uniformly distributed in the first heat exchange member 21 and improves heat exchange efficiency.

[0027] A water tank 30 and a water guide member 40 are provided in the first duct 12, and the coolant is used to exchange heat with the refrigerant in the condenser 20, thereby achieving effective heat dissipation from the condenser 20. Compared to conventional air conditioning systems, this prevents excess heat from being directly discharged to the external environment, reducing thermal pollution of the surrounding environment. At the same time, this heat exchange process improves energy utilization efficiency and reduces the energy consumption of the air conditioning system, resulting in significant energy savings.

[0028] The heat-reducing portable air conditioner of the present invention reduces the heat emitted to the outside environment, preventing the local ambient temperature from rising, which helps protect peripheral devices and equipment, reduces the risk of device failure, and extends the service life of the devices, making it particularly useful in areas sensitive to high temperatures, such as near electronic equipment rooms.

[0029] In one possible embodiment, a compressor 90 and an expansion valve are further provided within the housing 10. The compressor 90 compresses a low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas. The operation of the compressor 90 provides the power required for the refrigeration cycle. The condenser 20 cools the high-temperature, high-pressure refrigerant gas discharged from the compressor 90, liquefies it, and releases heat. The evaporator 80 absorbs heat from the indoor air to change the refrigerant from a liquid state to a gas state. The expansion valve is used to control the flow rate of the refrigerant, allowing it to expand and cool before entering the evaporator 80, thereby achieving a cooling effect.

[0030] The refrigeration cycle of the air conditioner according to the embodiment of the present invention includes the following four main steps: In the compression process, the compressor 90 sucks in low-temperature, low-pressure refrigerant gas and compresses it to a high-temperature, high-pressure gas, thereby increasing the pressure and temperature of the refrigerant and creating the conditions for the refrigerant to liquefy. The refrigerant changes from a low-temperature, low-pressure gas to a high-temperature, high-pressure gas.

[0031] During the condensation process, the high-temperature, high-pressure refrigerant gas enters the condenser 20 and exchanges heat with the cooling liquid on the outer surface of the condenser 20. The cooling liquid absorbs most of the heat, and the refrigerant gradually liquefies. Most of the heat in the refrigerant is exchanged with the cooling liquid. The refrigerant changes from a high-temperature, high-pressure gas to a high-temperature, high-pressure liquid.

[0032] In the throttling process, the liquid refrigerant passes through an expansion valve and enters the evaporator 80, which reduces the pressure and temperature of the refrigerant, allowing it to absorb heat in the evaporator 80. The refrigerant changes from a high-temperature, high-pressure liquid to a low-temperature, low-pressure liquid.

[0033] During the evaporation process, the low-temperature, low-pressure liquid refrigerant enters the evaporator 80, where it exchanges heat with the indoor air, absorbing the heat from the air and changing the refrigerant from a liquid state to a gas state, cooling the indoor air and achieving the cooling effect. The refrigerant changes from a low-temperature, low-pressure liquid to a low-temperature, low-pressure gas.

[0034] In the first duct 12 where the condenser 20 is located, the coolant is drawn to the outer wall of the first heat exchange member 21 through the water guide member 40, realizing heat exchange between the coolant and the refrigerant, with the coolant absorbing most of the heat. Meanwhile, the first fan 15 in the first duct 12 draws in external air, passes it through the condenser 20, and then expels the remaining small amount of heat to the external environment. This process ensures that the condenser 20 can effectively release the heat in the refrigerant, but heat release from the refrigerant can also be achieved by the coolant alone, achieving a predetermined effect.

[0035] In the second duct 13 where the evaporator 80 is located, the second fan 16 draws in indoor air, passes it through the evaporator 80, and then blows the cooled air into the room. This process ensures that the indoor air can be cooled effectively.

[0036] In an embodiment of the present invention, the heat-removal mobile air conditioner further includes a second heat exchanger, which is located in the water storage cavity 304 and exchanges heat with the coolant to reduce its temperature. The second heat exchanger is an independent heat exchanger, and may be a coil, plate, ferrule, or microchannel type. The temperature of the second heat exchanger is much lower than the current temperature of the coolant in the water storage cavity 304. The second heat exchanger directly contacts the coolant to complete the heat transfer, continuously absorbing the heat from the coolant and lowering the coolant temperature until it stabilizes at a design value, which is lower than the temperature of the refrigerant in the condenser 20. This ensures that the heat released by the refrigerant during the condensation process can be quickly and efficiently absorbed by the coolant.

[0037] 13 to 16, the second heat exchange element is at least one icebox 32, which is both a cold source and a cold storage unit, and which is a flat rectangular parallelepiped. The second heat exchange element is provided as a module that can be removed and replaced within the water tank 30 for easy replacement and maintenance. Most of the icebox 32 is immersed in the coolant in the water tank 30 to provide uniform and continuous cooling. The number of iceboxes 32 can be increased or decreased depending on the demand for cold energy, and the iceboxes 32 can continue to operate even if one of the iceboxes 32 expires.

[0038] The ice box 32 contains low-temperature phase-changeable ice as a refrigerant, which exchanges heat with the cooling liquid to reduce the temperature of the cooling liquid. The cooling liquid absorbs the heat of the refrigerant in the condenser 20 and then transfers the heat to the outer wall of the ice box 32, and the low-temperature phase-changeable ice in the ice box 32 absorbs the heat and provides and maintains the low temperature of the cooling liquid.

[0039] The low-temperature phase-changeable ice exists in the form of solid ice in the ice box 32, and the ice box 32 continues to absorb heat in the water tank 30, and the low-temperature phase-changeable ice gradually changes from a solid state to a liquid state. The solid-liquid phase change process of ice involves a large amount of latent heat exchange, and its own temperature remains almost constant, so the outer wall of the ice box 32 can maintain a low temperature for a long time, providing a stable cold end for the coolant, and the coolant can always be lower in temperature than the refrigerant in the condenser 20.

[0040] As shown in FIGS. 13 to 16, the water tank 30 comprises a housing 301 and a cover plate 302, which are pressed together with a sealing ring or a snap fit to form a removable whole.

[0041] The water storage cavity 304 is provided inside the housing 301. An opening is formed in one of the wall bodies of the housing 301. The cover plate 302 is placed over the opening to close the water storage cavity 304. The opening is located in the uppermost wall body of the housing 301 and has a shape that coincides with the outer contour of the cover plate 302. A flange edge for assembling with the lid is left around the opening.

[0042] Several convex ribs 33 are protruding on the wall body facing the opening of the housing 301. The several convex ribs 33 surround to form several storage areas 34. The convex ribs 33 are protruding structures on the bottom plate of the housing 301 and are distributed in a shape like the Chinese character "日" or "田".

[0043] Each ice box 32 is provided corresponding to one storage area 34. The ice box 32 has a first end and a second end along the first direction D1. The first direction D1 is the insertion direction of the ice box 32 (usually the direction of gravity). The first end is the lower end of the ice box 32, and the second end is the upper end of the ice box 32.

[0044] By restricting the position of the first end of the ice box 32 within the corresponding storage area 34, the movement of the ice box 32 along other directions except the first direction D1 is restricted. The outer shape of the lower end of the ice box 32 coincides with the inner contour of the area surrounded by the convex ribs 33. After the ice box 32 is inserted, the lower end of the ice box 32 is clamped by the four-sided convex ribs 33, restricting the degrees of freedom of the left, right, front, and back of the ice box 32. After the lower end of the ice box 32 is positioned, the ice box 32 can only continue to move up and down along the insertion direction and cannot move parallel in the horizontal direction.

[0045] The cover plate 302 is provided with a number of through-slots 35, which correspond one-to-one with the number of storage areas 34. The second end of the ice box 32 extends from the water tank 30 through the through-slots 35. The through-slots 35 have the same shape as the cross section of the top end of the ice box 32 but are slightly larger, ensuring smooth insertion and removal. The burrs of the through-slots 35 extend downward a certain distance to form a sleeve structure, providing an initial radial guide for the insertion of the ice box 32. After the second end of the ice box 32 passes through the through-slots 35, it is exposed a certain distance. The user can directly grasp the exposed end and pull it upward to replace it without opening the cover. Even during operation, an expired ice box 32 can be removed and a new ice box 32 inserted, eliminating the need to empty the water tank 30 or shut down the system, ensuring continuous, heat-free operation of the air conditioner.

[0046] As shown in Figures 14 and 16, a base 50 is provided in the housing 10, the condenser 20 is fixed to the base 50, and the water tank 30 may be provided below the base 50. The condenser 20 and the base 50 may be positioned by a snap fit, bolts or a fitting groove, ensuring that the condenser 20 does not shake during transportation and operation.

[0047] The base 50 has a water tank 51 inside, which is a cavity with the top surface of the base 50 recessed downward, or a tank body surrounded by slight protrusions. The coolant in the water tank 30 flows through the water tank 51, and the heat of the condenser 20 is first transferred to the coolant. The liquid dripping from the condenser 20 also falls directly into the water tank 51, preventing water from accumulating inside the housing 10 and realizing the circulation of the coolant.

[0048] The water tank 51 has a first liquid supply port 52 and a first liquid drain port 53 formed in the base 50, and the water storage cavity 304 has a second liquid supply port 36 and a second liquid drain port 37 formed in the water tank 30, thereby realizing closed circulation. As shown in FIG. 4 , the first liquid supply port 52 and the second liquid drain port 37 are connected via a first pipe 71, which is provided with a water pump 70. The water pump 70 guides the coolant in the water tank 30 into the water tank 51 via the first pipe 71. The first pipe 71 is a hose or a rigid pipe, one end of which is connected to the second liquid drain port 37 and the other end of which is connected to the first liquid supply port 52, with the middle portion serving as a power source for the water pump 70. The water pump 70 provides the sole power source, actively sending the coolant in the water tank 30 to the water tank 51 of the base 50, and the coolant in the water tank 51 is guided by the water guide member 40 to the outer wall of the first heat exchange member 21 to complete the heat exchange.

[0049] The first drain outlet 53 is connected to the second liquid supply port 36, and the coolant in the water tank 51 flows into the water storage cavity 304 through the first drain outlet 53 and the second liquid supply port 36. The first drain outlet 53 is located at the end of the water tank 51, the water tank 30 is located below the base 50, and the second liquid supply port 36 is located at the top of the water tank 30 and is vertically opposite the first drain outlet 53. The second liquid supply port 36 is a tapered port, which facilitates better collection of the coolant discharged from the first drain outlet 53. The coolant naturally overflows due to gravity and returns to the water tank 30, where it comes into contact with the ice box 32 again and is re-cooled, thereby forming a circulation of the coolant between the water tank 51 and the water tank 30.

[0050] A flow path for circulating the coolant is formed between the first liquid inlet 52 and the first liquid drain 53, and the water guide member 40 is positioned in the flow path to draw at least a portion of the coolant in the flow path to the first heat exchange member 21. The liquid flows from the first liquid inlet 52 into the water tank 51 and flows along the longitudinal direction of the water tank 51 to the first liquid drain 53. The water guide member 40 draws the coolant from the water tank 51 and over the first heat exchange member 21, forming a uniform liquid film. After absorbing heat, the liquid film falls back into the water tank 51, passes through the first liquid drain 53 and the second liquid inlet 36 again, and flows back into the water tank 30. The heat of the condenser 20 is absorbed by the coolant, and after the coolant warms up, it returns to the water tank 30 and is cooled again by the ice box 32. The coolant is constantly circulating, cooling, absorbing heat, and re-cooling.

[0051] 5 to 7, in the embodiment of the present invention, the water guide member 40 includes a drive motor 41 and a turntable 42 that is power-transmitted to the output shaft of the drive motor 41. The drive motor 41 is fixed to a base 50, and the output shaft of the drive motor 41 is inserted horizontally above the water tank 51. The turntable 42 serves as a rotating body that is power-transmitted to the output shaft of the drive motor 41 and rotates synchronously with the motor. The body of the drive motor 41 is enclosed in a sealed cover to prevent short circuits caused by splashing of the coolant.

[0052] A plurality of blades 43 are provided on the outer circumferential surface of the turntable 42, and the blades 43 are arranged at intervals in an annular pattern around the axis of the turntable 42. The blades 43 are radially or curved back and uniformly distributed on the outer circumference of the turntable 42, forming a symmetrical rotating mass and ensuring dynamic balance. There are gaps between adjacent blades 43, which stir up the coolant at the moment of rotation, and after being stirred up, the coolant naturally falls back into the water tank 51, completing efficient heat exchange and preventing the liquid from splashing outside the housing 10, keeping the interior of the machine dry and clean.

[0053] The driving motor 41 provides continuous rotational power to drive the turntable 42 in circular motion. As the turntable 42 rotates, the blades 43 stir up the coolant in the water tank 51, and the coolant is ejected tangentially by centrifugal force, forming an annular liquid curtain. The liquid curtain directly impacts the outer wall of the first heat exchange element 21, achieving uniform coverage. The thin and uniform liquid film improves heat exchange efficiency.

[0054] Preferably, as shown in FIG. 8, the water inlet side of the blade 43 has sawtooth segments 44. The blade 43 has a continuous sawtooth segment 44 on its water inlet side (i.e., the side that first contacts the liquid surface during rotation). The sawtooth segments 44 may be distributed along the entire length of the blade 43 or concentrated at the lower end, and the tooth shape is often an isosceles triangle or trapezoid. The sawtooth segments 44 divide the coolant into multiple streams as the blade 43 rotates, reducing resistance and preventing droplets from splashing due to large-area impacts. Furthermore, the coolant changes direction multiple times before leaving the blade 43, making it easier for the coolant film to separate from the surface of the blade 43 and forming a dense, uniform annular liquid curtain.

[0055] In one possible embodiment, the housing 10 is provided with an opening that opens into one side wall of the housing 10, the shape of which matches the outer contour of the water tank 30, and burring or reinforcing ribs are provided around the opening to maintain the rigidity of the housing 10 and provide a guide for subsequent removal. The storage cavity 11 communicates with the outside through the opening, forming a direct passage between the internal water tank 30 and the outside. The water tank 30 can be removed from the storage cavity 11 through the opening without removing the side panel or back cover of the housing 10. By removing the water tank 30, the ice box 32 can be replaced, and after the ice box 32 is replaced, it can be pushed back to resume operation.

[0056] 11 and 12, the water tank 30 is provided with a through-hole 303, which connects the water storage cavity 304 with the outside. The through-hole 303 is a through-hole opened in the wall of the water tank 30, which directly connects the internal water storage cavity 304 with the outside space. The through-hole 303 serves as an outlet for the coolant to flow out, and also provides mounting positioning for the subsequent water nozzle 38.

[0057] A water nozzle 38 is provided in the through hole 303, and the water nozzle 38 has a first end and a second end, the first end of the water nozzle 38 extending into the water storage cavity 304 and connected to the water pipe 31, and the second end of the water nozzle 38 extending from the water tank 30. The water nozzle 38 is a rigid or semi-rigid pipe, both ends of which extend into and out of the water storage cavity 304, respectively, and the first end extending into the water storage cavity 304 serves as a connection port for the internal water pipe 31, and the second end extending out of the water tank 30 may be connected to the relay member 61 of the adapter base 60.

[0058] One end of the water pipe 31 is connected to the first end of the water nozzle 38 and is either sealed or integrally formed, and the other end of the water pipe 31 is freely suspended. During pumping, the negative pressure generated by the water pump 70 passes through the relay member 61 and the water nozzle 38 in that order to reach the water pipe 31, and continuously sucks out the coolant in the water storage cavity 304.

[0059] The heat-exhaust-less portable air conditioner further includes an adapter base 60, which is provided with a relay member 61, which is fixed to the adapter base 60 by snap-fit, screws or fast plugging. The relay member 61 has a hollow coolant passage formed inside. The relay member 61 is connected to a first pipeline 71, which is directly inserted into the relay member 61 and can be locked with a fast plug, clamp or screws.

[0060] The relay member 61 contains a check valve 62, which is detachably connected to the second end of the water nozzle 38. The water nozzle 38 has an outer diameter that matches the port 612 of the check valve 62, and can be connected by being inserted linearly into the check valve 62. The check valve 62 is a check valve that opens with forward pressure and instantly closes in the reverse direction. When the water nozzle 38 and the check valve 62 are connected, the check valve 62 only allows the coolant in the water storage cavity 304 to flow sequentially through the water pipe 31, the water nozzle 38, the check valve 62, and the relay member 61 to the first pipe 71.

[0061] When the water pump 70 in the air conditioner is running, the backflow valve 62 is pushed open by the water flow, allowing the water in the water tank 30 to smoothly enter the first pipe 71. When the user pulls out or moves the water tank 30, the connection between the backflow valve 62 and the first pipe 71 is cut off, and the backflow valve 62 immediately cuts off the water passage, preventing the coolant in the water tank 30 from leaking out. When the pressure in the first pipe 71 fluctuates, the backflow valve 62 also prevents the coolant from entering the water tank 30 in the reverse direction.

[0062] In an embodiment of the present invention, the backflow valve 62 is made of an elastic material, and the entire backflow valve 62 or at least the valve body portion is integrally molded from an elastic polymer material such as silica gel, EPDM, or TPE, which on the one hand can form a surface seal with the water nozzle 38, and on the other hand, the backflow valve 62 can be opened and closed by utilizing the elastic recovery force of the material itself.

[0063] As shown in Figures 23 and 25, a flow path 621 is provided within the check valve 62. The flow path 621 is a single through-passage molded within the check valve 62. The flow path 621 has a first end (inlet) and a second end (outlet), and serves as a path for the coolant to enter the check valve 62 from the water nozzle 38. The water nozzle 38 extends from the first end of the flow path 621 into the flow path 621. In one possible embodiment, the outer diameter of the second end of the water nozzle 38 is slightly larger than the inner diameter of the first end of the flow path 621, forming an interference fit. After the water nozzle 38 is inserted, the check valve 62 expands radially, generating uniform cling pressure. This allows the outer wall of the water nozzle 38 to come into surface contact with the inner wall of the flow path 621, forming a seal. This eliminates the need for an additional O-ring and avoids the risk of leakage due to deterioration or misalignment of the sealing ring.

[0064] As shown in Figure 23, a slit-shaped opening 622 is formed at the second end of flow path 621. Slit-shaped opening 622 is a linear slit (duckbill or straight line) formed by two elastic lips that naturally fit together. During the pumping stage, when negative pressure from water pump 70 acts on the outside of slit-shaped opening 622, the lips are sucked open, expanding slit-shaped opening 622 into a roughly elliptical hole, allowing the coolant to flow out smoothly. When the air conditioner is turned off, the lips immediately close due to the elasticity of the material and the external atmospheric pressure, and the width of the slit approaches zero, achieving instantaneous sealing.

[0065] In one possible embodiment, as shown in FIGS. 23 and 25 , the check valve 62 has a radially constricted area. Within the radially constricted area, the walls on both sides of the flow passage 621 gradually contract along the length of the flow passage 621, forming a slope 623. A slit-shaped opening 622 is formed at the end of the slope 623. The radially constricted area of ​​the check valve 62 forms an elastic lip due to a gradual change in wall thickness. From the beginning to the end of the constricted area, the inner wall of the flow passage 621 exhibits a symmetrical slope, gradually transitioning from a circular cross section to a flat, elongated gap. During pumping, negative pressure causes the walls on both sides of the slope 623 to slightly expand outward, gradually expanding the cross-sectional area of ​​the flow passage 621 along the slope, thereby reducing flow resistance. When operation is stopped, the slope 623 quickly closes due to elastic rebound, creating a wedge-type self-locking mechanism, achieving zero leakage at low pressure differences and improving sealing reliability.

[0066] Furthermore, the check valve 62 has a plurality of convex rings 624 protruding from the flow path 621. The convex rings 624 are annular protrusions that are integrally formed with the check valve 62 from an elastic material and may have a semicircular, trapezoidal, or triangular cross section. The convex rings 624 are elastically deformable, automatically compensating for the outer diameter tolerance and long-term wear of the water nozzle 38. The convex rings 624 are spaced apart along the length of the flow path 621, forming a plurality of sealing surfaces. When the water nozzle 38 is inserted into the water nozzle 38, the water nozzle 38 pushes open each convex ring 624 in turn, forming a sealing interface for each convex ring 624 that passes through it. This allows multiple annular seals to be formed between the outer wall of the water nozzle 38 and the flow path 621 without the need for additional sealing rings, significantly reducing the likelihood of leakage.

[0067] 23, in one possible embodiment, the end face of the check valve 62 adjacent to the adapter base 60 extends radially outward to form a first position limiting protrusion 625. The first position limiting protrusion 625 has an outer diameter larger than the inner diameter of the through-hole 303 and is ring-shaped or has a localized lug shape. The first position limiting protrusion 625 abuts against the adapter base 60, and the inner wall of the relay member 61 and the outer wall of the adapter base 60 clamp the first position limiting protrusion 625, forming a mechanical stop position and end face seal, preventing the coolant from seeping out, ensuring the accuracy of the insertion position of the water nozzle 38, and ensuring smooth pumping of the coolant. The check valve 62 ensures a reliable seal, and is quicker to assemble and more securely positioned.

[0068] 12 and 20, the water nozzle 38 has a cylindrical structure, and a second limiting protrusion 381 is provided on the outer surface of the water nozzle 38. The second limiting protrusion 381 is a radial boss 63 integrally molded on the outer wall of the water nozzle 38, and the outer diameter of the second limiting protrusion 381 is larger than the inner diameter of the through-hole 303. When the water nozzle 38 passes through the through-hole 303 from the outside to the inside, the second limiting protrusion 381 ultimately abuts against the outer surface of the water tank 30, forming an external stop position, providing a clear axial positioning reference, and preventing the water nozzle 38 from sliding excessively inward. The second limiting protrusion 381 forms an end-face seal or tight fit with the outer surface of the water tank 30, preventing the coolant from seeping out along the through-hole 303.

[0069] 12 and 21, a position limiting elastic piece 39 is fitted to the water nozzle 38. The position limiting elastic piece 39 is an open ring, C-shaped collar, or corrugated gasket made of metal or highly elastic plastic. It is fitted to the outer wall of the water nozzle 38 and can slide a certain distance along the axial direction. In one possible embodiment, a third position limiting protrusion 382 is protruded from the outer surface of the water nozzle 38 and is used to limit the axial movement of the position limiting elastic piece 39.

[0070] The wall where through-hole 303 is located is located between second position limiting protrusion 381 and position limiting elastic piece 39, and second position limiting protrusion 381 is used to abut the outer surface of water tank 30, and position limiting elastic piece 39 is used to abut the inner surface of water tank 30 to prevent water nozzle 38 from escaping. When it is necessary to remove water nozzle 38, water nozzle 38 can be pulled out of water tank 30 by moving position limiting elastic piece 39 axially until it is detached from water nozzle 38. The inner diameter of water nozzle 38 is smaller than the inner diameter of through-hole 303, so that water nozzle 38 has a certain radial movement distance.

[0071] The position limiting elastic piece 39 is made of an elastic material, and the entire position limiting elastic piece 39 is pressed / injection molded as a single piece from stainless steel, spring steel, or high-elastic plastic, causing a radially recoverable elastic deformation, and the elastic recovery force of the material can be used to provide sustained and stable radial pressure for engagement with the subsequent water nozzle 38.

[0072] 21, the position-limiting elastic piece 39 includes an annular piece 391 and a number of spaced apart position-limiting protrusions 392 protruding from the inner surface of the annular piece 391. The outer contour of the annular piece 391 is a complete ring, and the position-limiting protrusions 392 are evenly spaced along the circumference and protrude from the inner surface of the annular piece 391 toward the central axis in a cantilevered shape. The multiple position-limiting protrusions 392 jointly bear force, ensuring uniform load distribution and avoiding single-point stress concentration. The ends of the several position-limiting protrusions 392 away from the annular piece 391 jointly define a through-hole, into which the water nozzle 38 extends. During assembly, the outer wall of water nozzle 38 pushes open the through hole, causing position limiting protrusion 392 to extend radially outward, instantly expanding the through hole, and position limiting protrusion 392 engages with the outer wall of water nozzle 38, providing a radial pressing force that allows position limiting elastic piece 39 to engage with water nozzle 38. During removal, simply compressing the protrusion radially with a pointed clamp or your fingers instantly expands the through hole, allowing position limiting elastic piece 39 to be detached from water nozzle 38.

[0073] 11, 12 and 22, the relay member 61 is removably fixed to the outer surface of the adapter base 60. The relay member 61 is an independent sleeve that is repeatedly and detachably fixed to the outer wall of the adapter base 60 by means of snap fitting, screws, a sliding groove, magnetic attraction, etc. In one possible embodiment, the relay member 61 is attached and fixed to the adapter base 60 by a screw method. When attached, the relay member 61 is aligned with a preset boss 63 of the adapter base 60. The boss 63 has a screw hole, and the relay member 61 has a pre-hole. After aligning the pre-hole with the screw hole, a bolt passes through the pre-hole and is then connected to the bolt. When removing the bolt, the bolt can be simply rotated in the reverse direction, which is convenient and fast.

[0074] As shown in FIG. 12, the relay member 61 has an accommodating groove 611 therein, which has a groove opening at one end close to the adapter base 60, the side of the accommodating groove 611 facing the water tank 30 being completely open, the check valve 62 extending from the groove opening into the accommodating groove 611, the relay member 61 providing mechanical protection for the check valve 62 and preventing collisions during transportation or installation, and there is a gap or a slight interference fit between the outer wall of the check valve 62 and the accommodating groove 611, which allows the gas / coolant to flow smoothly while limiting its radial vibration. The receiving groove 611 has a port 612 at one end away from the adapter base 60, which abuts the external water pump 70. When pumping, the coolant flows through the water pipe 31, the water nozzle 38, the check valve 62, the receiving groove 611, and the port 612 into the first pipeline 71. The relay member 61 integrates the check valve 62 into a coolant fast-plug module that can be quickly removed and replaced, protecting the check valve 62 and achieving standard abutment, improving the versatility and reliability of the water tank 30.
