Therefore, it should not be understood as a limitation on the present invention.

[0031] In the present invention, unless otherwise clearly stipulated and limited, terms such as "connected", "provided with", "having" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be said to be a mechanical connection, or it can be directly connected, or it can be connected through an intermediate medium. For those skilled in the art, the basic meaning of the above terms in the present invention can be understood according to the specific circumstances.

[0032] like Figure 1 , Figure 2 , Figure 3 The first embodiment of a rainwater separator of the present invention is shown, comprising a housing 1 and a plurality of blades 2 disposed in the housing 1, wherein the plurality of blades 2 are evenly distributed, the blades 2 comprising a V-shaped blade body 21 and horizontal extension bodies 22 disposed at both ends of the V-shaped blade body 21, the opening of the V-shaped blade body 21 being arranged sideways, a first connecting member 23 being arranged at the bottom end of the V-shaped blade body 21, a second connecting member 24 being arranged at one end of the V-shaped blade body 21 away from the air inlet, a shaft 25 being respectively arranged through the first connecting member 23 and the second connecting member 24, both ends of the shaft 25 being fixedly connected to the housing 1, the shaft 25 being clamped and fixed to the first connecting member 23 and the second connecting member 24, and a first drainage hole 3 being arranged at a position close to the first connecting member 23 and the second connecting member 24 on one side of the housing 1;

[0033] The V-shaped blade body 21 includes a first inclined portion 211 and a second inclined portion 212, wherein the first inclined portion 211 is close to the air inlet of the housing 1, and the second inclined portion 212 is close to the air outlet of the housing 1;

[0034] The first connecting member 23 includes a first extending portion 231 extending along one end of the second inclined portion 212 and a second extending portion 232 inclined and bent upward along the outer end of the first extending portion 231 , wherein the second extending portion 232 is parallel to the first inclined portion 211 ;

[0035] The second connecting member 24 includes a third extension portion 241 that is bent upward along one end of the V-shaped wind blade body 21 and a fourth extension portion 242 that is bent upward along the outer end of the third extension portion 241. The third extension portion 241 and the second inclined portion 212 are axially symmetrically arranged with the horizontal extension body 22 as the center, and the fourth extension portion 242 is parallel to the second inclined portion 212.

[0036] The fan blade 2 in the present invention includes a V-shaped fan blade body 21 and a horizontal extension body 22. The V-shaped fan blade body 21 has a good barrier effect on the gas containing moisture. The gas passes through the gap between the two adjacent fan blades 2 and is initially isolated by the two V-shaped fan blade bodies 21. Rainwater and impurities fall downward due to their own gravity, so that the rainwater and impurities are separated from the air. After the air containing some moisture passes through the two adjacent V-shaped fan blade bodies 21 for multiple collisions, some moisture is separated from the air, which has a certain dehumidification effect on the air and improves the comfort of the air. The two adjacent V-shaped fan blade bodies 21 leave a good induced air channel for the introduction of fresh air to ensure the induced air volume.

[0037] Among them, the horizontal extension part 22 is set to provide space for rainwater or impurities to fall. The wind passes through the horizontal extension part 22 between two adjacent fan blades 2 and flows to the first inclined part 211, where it collides with the first time and changes direction. The wind flows from the first inclined part 211 to the second inclined part 212, where it collides with the second time and changes direction. Then, the wind flows out from the second inclined part 212 to the horizontal extension part 22, where it collides with the third time and changes direction. This structural design increases the number of times the wind collides with the fan blades 2, thereby ensuring the separation effect of rainwater and impurities. The horizontal extension part 22 not only has a certain storage effect on impurities and moisture, but also ensures its air intake at the air inlet, thereby changing the influence of the traditional inclined plate on the wind intake.

[0038] Furthermore, a slot 26 for allowing the shaft rod 25 to pass through is provided between the connection between the first extension portion 231 and the second extension portion 232 and between the connection between the third extension portion 241 and the fourth extension portion 242 . The upper end of the slot 26 extends upwards of the shaft rod 25 and covers the shaft rod 25 therein.

[0039] Furthermore, the slot 26 has a plurality of circumferentially distributed grooves 27, and the outside of the shaft 25 has a plurality of circumferentially distributed ribs 28. The extension direction of the grooves 27 and the ribs 28 is consistent with the extension direction of the V-shaped fan blade body 21, and the ribs 28 and the grooves 27 are arranged in sequence.

[0040] The fan blade 2 is fixedly connected to the housing 1 via the shaft 25. The shaft 25 is clamped with the fan blade 2 and then installed with the housing 1, which facilitates the installation of the special fan blade 2 and has high connection stability.

[0041] Furthermore, a removable filter structure 4 is provided at one end of the shell 1 away from the air inlet, and buckle assemblies 5 are provided at both ends of the filter structure 4.

The extension direction of the connecting plate 44 is perpendicular to the extension direction of the U-shaped track 43. Both ends of the connecting plate 44 extend outwardly with a bent portion 46, and the outer end face of the connecting plate 44 is provided with a handle 45.

[0043] Further, such as Figure 5 As shown, the buckle assembly 5 includes a fixing plate 51, a locking tongue 52 and a clamping body 53. The fixing plate 51 and the locking tongue 52 are hinged via a movable shaft 54, and a spring 55 is sleeved on the movable shaft 54. When the spring 55 is in a natural state, the clamping body 53 is sleeved on the bending portion 46 to clamp the bending portion 46. When the locking tongue 52 is rotated to make the spring 55 in a compressed state, the clamping body 53 is away from the bending portion 46 to relax the bending portion 46.

[0044] The filter structure 4 is connected to the shell 1 by a track pull-out method, and is fixedly connected to the shell 1 by a snap-fit ​​assembly 5, so as to realize quick cleaning, installation and replacement of the filter structure 4. The structure is cleverly designed and flexible and convenient to use. It changes the traditional bolt-fixed connection method, which is convenient for installation and replacement while avoiding damage to the shell caused by long-term tightening of the bolts.

[0045] The U-shaped rails 43 are general rails, and the openings of the two U-shaped rails 43 are arranged to face upward, wherein both side ends of the filter frame 41 of the filter structure 4 are horizontally embedded in the corresponding U-shaped rails 43 for easy pulling.

[0046] Furthermore, the housing 1 is provided with a plurality of second drainage holes 6 evenly distributed horizontally near its air inlet, and the plurality of first drainage holes 3 and second drainage holes 6 facilitate the discharge of rainwater and impurities.
