[0039] Example 1

[0040] See Figures 1 to 5 As shown, the water vapor separation device provided in this application is used for the air inlet of an automotive air conditioner. When external air flows through the water vapor separation device, the water vapor separation device can separate the moisture in the air to reduce the humidity of the air entering the automotive air conditioner.

[0041] Specifically, the water-air separation device includes a water storage box 101, an air intake pipe 102, and a drying element 103; the water storage box 101 is provided with a water storage chamber, a first inlet 106, and a first outlet 107, the first inlet 106 and the first outlet 107 being connected to the water storage chamber; the air intake pipe 102 is provided with a rotary channel, a second inlet 108, and a second outlet 109, the second inlet 108 and the second outlet 109 forming a rotary channel; the first outlet 107 is connected to the second inlet 108, the second outlet 109 is connected to the air intake of the car air conditioner, and the drying element 103 is located between the second outlet 109 and the air intake of the car air conditioner.

[0042] Specifically, when the car's air conditioning is turned on, outside air is drawn into the water storage box 101 through the first inlet 106. Under the influence of gravity, rainwater falls to the bottom of the water storage box 101 and is collected in the water storage chamber, thus separating most of the rainwater. The air then enters the intake duct 102 through the first outlet 107 and the second inlet 108. The intake duct 102 is equipped with a rotary channel. When air enters the rotary channel, the airflow forms a U-shaped flow path, allowing the air to slow down within the intake duct 102. Micro-particle rainwater in the air can then condense and collect at the bottom of the rotary channel, allowing any trace amounts of moisture drawn into or splashed into the intake duct 102 to settle and settle within the intake duct 102, further separating the rainwater.

[0043] A dryer 103 is also installed at the second exit 109 of the rotary channel. Air flows through the dryer 103 and then enters the air intake of the car's air conditioning system. The dryer 103 is mainly responsible for drying and dehumidifying the air with high humidity, and it can also effectively block dust particles. As the last line of defense for air entering the car's air conditioning system, the dryer 103, in addition to drying the air and blocking dust, also has a certain effect of silver ion disinfection and sterilization.

[0044] The drying unit 103 specifically includes a non-woven fabric and a drying box, through which air flows sequentially. The non-woven fabric is installed at the second outlet 109 via a fixed pressure plate. The drying box is installed at the second outlet 109 and is surrounded by sealing sponge. The main components of the drying box are granular activated carbon, anhydrous calcium chloride, and silica gel.

[0045] The water-air separation device provided in this application can separate rainwater and air multiple times by setting up a water storage box 101 and an air intake pipe 102. Furthermore, the air is dehydrated at the end of the air intake pipe 102, thereby making the air entering the car air conditioner drier, improving the air quality inside the car, achieving the purpose of preventing mold, and enabling the car air conditioner to heat and cool quickly.

[0046] In the optional solutions of this embodiment, such as Figure 4 As shown, the intake pipe 102 includes a rotating section 110 and a connecting section 111. A second inlet 108 is located in the rotating section 110, connecting it to the water storage box 101, allowing air from the water storage box 101 to directly enter the rotating section 110. The rotating section 110 has a snail-shell-like structure, forming a spiral shape that creates a U-shaped flow path. This slows down the air entering the rotating section 110, allowing fine raindrops in the air to condense and collect at the bottom of the rotating section 110.

[0047] The connecting portion 111 is connected to the rotating portion 110, and the second outlet 109 is opened in the connecting portion 111; the connecting portion 111 forms a connecting channel extending in a straight direction, and the second outlet 109 is located at the end of the connecting channel. Specifically, the connecting portion 111 extends upward in an inclined straight direction, the bottom end of the connecting portion 111 is connected to the rotating portion 110, and the top end of the connecting portion 111 has a second outlet 109. The actual position of the second outlet 109 is adapted to the air inlet of the car air conditioner. With this arrangement, the bottom of the rotating portion 110 is the lowest point of the air intake pipe 102, so that micro-particle rainwater can be collected at the bottom of the air intake pipe 102, preventing the flowing air from carrying rainwater into the car air conditioner.

[0048] In an optional embodiment, the rotating part 110 and the connecting part 111 form a receiving space 112, and the water storage box 101 is embedded in the receiving space 112, which makes the overall assembly structure of the air intake pipe 102 and the water storage box 101 more compact and reduces the space occupation.

[0049] In the optional solutions of this embodiment, such as Figure 5 As shown, the water storage box 101 includes a first top wall 104 and a second top wall 105. The first top wall 104 is adapted to the contour of the car hood, thus achieving a consistent overall appearance. The first top wall 104 has a first inlet 106, allowing air to enter the water storage box 101 from above, while rainwater settles at the bottom of the water storage box 101. The second top wall 105 is inclined relative to the first top wall 104, and has a first outlet 107 located diagonally above the water storage box 101. This ensures that the height of the first outlet 107 is a certain distance from the bottom of the water storage box 101, making it less likely for flowing air to carry rainwater into the air intake pipe 102. Furthermore, because the first outlet 107 is inclined, the second inlet 108, which connects to it and is located in the air intake pipe 102, is also inclined, so that the bent turning part 110 does not protrude excessively and interfere with the hood.

[0050] In an optional embodiment, the water storage box 101 further includes a guide wall 113; the guide wall 113 is inclined and opposite to the first inlet 106 to guide the water flow to the bottom of the water storage box 101; an absorbent pad 114 is provided on the guide wall 113.

[0051] In this embodiment, the inclined guide wall 113 is adapted to the connecting portion 111 of the air intake pipe 102. When rainwater enters the water storage box 101 from the first inlet 106, the rainwater can flow along the inclined guide wall 113 to the bottom of the water storage box 101. A water-absorbing pad 114, specifically a sponge, is also provided on the guide wall 113. The sponge has a certain water absorption and cushioning effect, which can effectively prevent rainwater from splashing into the box, thus providing a buffering effect against rainwater.

[0052] In an optional embodiment, the bottom of the water storage box 101 is also provided with a first discharge port. When rainwater enters the water storage box 101 from the first inlet 106, the rainwater can be collected in the water storage chamber, and the collected rainwater can be discharged to the outside of the vehicle from the first discharge port. The height of the first inlet 106 and the height of the first outlet 107 are both higher than the first discharge port, which can prevent rainwater from entering the air intake pipe 102.

[0053] Furthermore, a second discharge port is provided at the bottom of the intake pipe 102, and micro-particle rainwater condenses at the bottom of the intake pipe 102, allowing the rainwater to be discharged outside the vehicle from the second discharge port. The height of the second inlet 108 and the height of the second outlet 109 are both higher than the second discharge port, which can prevent rainwater from entering the car's air conditioning system.

[0054] In an optional embodiment, the water storage box 101 further includes a first bottom wall 115, with a first confluence channel 116 at its lower end. A first discharge port is provided at the bottom of the first confluence channel 116 to prevent water accumulation in the water storage box 101. The air intake pipe 102 includes an inclined second bottom wall 117, with a second confluence channel 118 at its lower end. A second discharge port is provided at the bottom of the second confluence channel 118 to prevent water accumulation in the air intake pipe 102.

[0055] In an optional embodiment, a first drain pipe 119 is provided at the first discharge port, and a second drain pipe 120 is provided at the second discharge port. The second drain pipe 120 is connected to the first drain pipe 119 to form a siphon effect.

[0056] In this embodiment, the first drain pipe 119 is used to drain rainwater from the water storage box 101, and the second drain pipe 120 is used to drain rainwater from the air intake pipe 102. The first drain pipe 119 and the second drain pipe 120 can be made of high and low temperature resistant rubber material, and the first drain pipe 119 is connected to the first drain outlet by a clamp, and the second drain pipe 120 is connected to the second drain outlet by a clamp. Furthermore, the first drain pipe 119 and the second drain pipe 120 are fixed inside the vehicle's engine compartment using clips.

[0057] Furthermore, since the amount of rainwater in the water storage box 101 is greater, the diameter of the first drain pipe 119 is larger than that of the second drain pipe 120 to achieve rapid drainage. Further, the end of the second drain pipe 120 furthest from the air intake pipe 102 is connected to the middle of the first drain pipe 119. When the first drain pipe 119 drains water, the second drain pipe 120 creates a siphon effect, thereby completely draining the water inside the air intake pipe 102.

[0060] In an optional embodiment, the water-air separation device further includes a first filter and a second filter 121. The first filter is specifically a grid located at the first inlet 106, used to block visible objects of larger size or area, such as leaves, branches, and insects, from entering the water storage box 101. The second filter 121 is specifically a metal filter screen (12 mesh optional), located between the first outlet 107 and the second inlet 108, which can filter out any remaining debris and smaller impurities, and can also, to some extent, prevent rainwater from being drawn into the suction pipe 102. In practical applications, different sizes of filter screens can be selected according to filtration requirements.
