[0041] In this embodiment, since the crossflow wind wheel 100 includes at least two wind wheel segments 10, the at least two wind wheel segments 10 can be freely assembled to set the length of the crossflow wind wheel 100 according to user needs, thereby improving the user experience. The crossflow wind wheel 100 is configured as at least two wind wheel segments 10. Compared with the one-piece crossflow wind wheel 100, the production and processing technology of the wind wheel segments 10 is simpler, and it is simpler to transport, thereby preventing damage during transportation and reducing the production cost of the crossflow wind wheel 100.

[0042] Furthermore, the two wind wheel segments 10 are magnetically connected via a magnetic structure, the connection structure is simple, the processing technology is simple, the installation and removal of the wind wheel segments 10 are simpler and more convenient, and the production cost of the crossflow wind wheel 100 is further reduced.

[0043] In some embodiments of the present invention, a rotation-stopping device is provided between every two adjacent wind wheel segments 10 to prevent the relative rotation between the two wind wheel segments 10 .

[0044] In this embodiment, a rotation-stopping device is provided between two adjacent wind wheel segments 10 to prevent the crossflow wind wheel 100 from shaking during operation, thereby improving the operating stability of the crossflow wind wheel 100 and avoiding affecting the air quality of the crossflow wind wheel 100, thereby improving the user experience.

[0045] In some embodiments of the present invention, Figure 1 As shown, each wind rotor segment 10 includes two end plates 110 and blades 120 disposed between the two end plates 110. In each adjacent two wind rotor segments 10, a magnetic structure and a rotation-stopping device are disposed between two end plates 110 that are close to each other.

[0046] In this embodiment, the magnetic structure and the anti-rotation device are arranged on the two end plates 110 of the wind wheel segment 10. When the crossflow wind wheel 100 is installed, the two end plates 110 of the two wind wheel segments 10 that are close to each other are adsorbed together by the magnetic force of the magnetic structure, and the anti-rotation structure makes the connection between the two wind wheel segments 10 more secure, further improving the stability of the operation of the crossflow wind wheel 100, avoiding affecting the air quality of the crossflow wind wheel 100, and thus improving the user experience.

[0047] In some embodiments of the present invention, Figures 2 to 4As shown, in each of two adjacent wind wheel segments 10, two end plates 110 close to each other are respectively a first end plate 111 and a second end plate 112. The magnetic structure includes a first magnetic member 210 and a second magnetic member 220, which are respectively arranged on the first end plate 111 and the second end plate 112. One of the first magnetic member 210 and the second magnetic member 220 is a magnet, and the other of the first magnetic member 210 and the second magnetic member 220 is made of iron.

[0048] In this embodiment, the first end plate 111 and the second end plate 112 are connected by adsorption through the magnetism between the magnet and the iron. The connection method is simple, the installation and disassembly between the wind wheel segments 10 are convenient, and the production cost of the crossflow wind wheel 100 is reduced. For example, the first magnetic member 210 is a magnet, and the second magnetic member 220 is iron. Alternatively, the first magnetic member 210 is iron, and the second magnetic member 220 is a magnet.

[0049] In some embodiments of the present invention, Figures 2 to 4 As shown, in each adjacent two wind wheel segments 10, the two end plates 110 close to each other are respectively the first end plate 111 and the second end plate 112. The magnetic structure includes a first magnetic member 210 and a second magnetic member 220, which are respectively arranged on the first end plate 111 and the second end plate 112. The first magnetic member 210 and the second magnetic member 220 are both magnets.

[0050] In this embodiment, the first end plate 111 and the second end plate 112 are connected by magnetism between magnets. The connection method is simple, and the installation and disassembly of the wind wheel segments 10 are convenient, thereby reducing the production cost of the crossflow wind wheel 100.

[0051] In other embodiments of the present invention, each wind wheel segment 10 includes a first end plate 111 and a second end plate 112, and the first end plate 111 of the wind wheel segment 10 and the second end plate 112 of another adjacent wind wheel segment 10 are magnetically adsorbed and connected via a magnetic structure.

[0052] In this embodiment, each wind wheel segment 10 has the same structure, and only one mold is needed when producing and processing the wind wheel segment 10, which simplifies the processing of the wind wheel segment 10, reduces the production cost of the wind wheel segment 10, and further reduces the production cost of the crossflow wind wheel 100.

A second groove 50 is provided on the second end plate 112, and the first groove 40 and the second groove 50 are arranged opposite to each other.

[0055] In this embodiment, the first magnetic member 210 is installed in the first groove 40, and the second magnetic member 220 is installed in the second groove 50. When installing two wind wheel segments 10, the first magnetic member 210 and the second magnetic member 220 are attracted to each other, driving the first end plate 111 and the second end plate 112 to approach each other until the first end plate 110 and the second end plate 112 are in contact with each other. The first magnetic member 210 is more firmly fixed on the first end plate 111 and the second magnetic member 220 is more firmly fixed on the second end plate 112, thereby improving the stability of the installation of the first end plate 111 and the second end plate 112.

[0056] In some embodiments of the present invention, the first magnetic member 210 is a magnet, the second magnetic member 220 is made of iron, and the second end plate 112 is the second magnetic member 220. The first end plate 111 is provided with a first groove 40, and the first magnetic member 210 is disposed in the first groove 40, so that the first end plate 111 and the second end plate 112 are in contact with each other.

[0057] In this embodiment, the second end plate 112 is made of iron, and the first end plate 111 is provided with a first groove 40, in which the magnet is provided. The first end plate 111 and the second end plate 112 are connected by adsorption through the magnetism between the magnet and the iron, and the connection method is simple. The second end plate 112 itself is the second magnetic member 220, which is more convenient when producing the wind wheel segment 10, reduces the production cost of the wind wheel segment 10, and further reduces the production cost of the crossflow wind wheel 100.

[0058] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the anti-rotation device includes a protrusion groove 320 and a protrusion 310 inserted into the protrusion groove 320 , one of the protrusion 310 and the protrusion groove 320 is disposed on the first end plate 111 , and the other is disposed on the second end plate 112 .

[0059] In this embodiment, the relative rotation between the two wind wheel segments 10 is prevented by the plug-in fit of the protrusion 310 and the protrusion groove 320. The plug-in anti-rotation structure is simple, which reduces the difficulty of the processing technology of the wind wheel segment 10 and reduces the production cost of the wind wheel segment 10. The installation method of the wind wheel segment 10 is simple and convenient, and is easy to operate.

[0060] In some embodiments of the present invention, Figures 5 to 7As shown, the anti-rotation device includes a latch hole 330 and a buckle 340 inserted into the latch hole 330 , one of the buckle 340 and the latch hole 330 is disposed on the first end plate 111 , and the other is disposed on the second end plate 112 .

[0061] In this embodiment, the relative rotation between the two wind rotor segments 10 is prevented by the snap fit between the snap fit 340 and the snap fit hole 330. The snap fit 340 is not easy to fall off after being inserted into the snap fit hole 330, thereby increasing the stability of the connection between the wind rotor segments 10. In addition, the anti-rotation structure of the snap fit is simple, which reduces the difficulty of the processing technology of the wind rotor segment 10, reduces the production cost of the wind rotor segment 10, and the installation method of the wind rotor segment 10 is simple and convenient, and easy to operate.

[0062] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the anti-rotation device includes a protrusion groove 320 and a protrusion 310 inserted into the protrusion groove 320, one of which is disposed on the first end plate 111, and the other is disposed on the second end plate 112. In addition, the anti-rotation device includes a clamping hole 330 and a buckle 340 inserted into the clamping hole 330, one of which is disposed on the first end plate 111, and the other is disposed on the second end plate 112.

[0063] In this embodiment, the relative rotation between the two wind rotor segments 10 is prevented by the plug-in fit between the protrusion 310 and the protrusion groove 320 and the snap fit between the buckle 340 and the snap hole 330. The anti-rotation device has a simple structure, reduces the difficulty of the processing technology of the wind rotor segment 10, reduces the production cost of the wind rotor segment 10, and the installation method of the wind rotor segment 10 is simple and convenient, and easy to operate. In addition, the buckle 340 is not easy to fall off after being inserted into the snap hole 330, which increases the stability of the connection between the wind rotor segments 10.

[0064] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, each buckle 340 includes two symmetrically arranged buckle parts. Each buckle part includes a clamping plate 341 extending along the axial direction of the crossflow impeller 100, and a clamping protrusion 342 arranged at the end of the clamping plate 341. The two buckle parts are arranged in sequence and spaced apart along the radial direction of the crossflow impeller 100.

[0065] In this embodiment, when the buckle 340 and the hole 330 are installed, the two buckle parts are close to each other under the action of the hole 330, so that the buckle part returns to its original position after the protrusion 342 passes through the hole 330, and the protrusion 342 blocks the side of one end plate 110 away from the other end plate 110, thereby realizing the connection between the two end plates 110.

[0066] In some embodiments of the present invention, Figure 6As shown, the two clamping plates 341 of the clamping portion are located on both sides of the radius on the cross-section of the crossflow impeller 100 .

[0067] In some preferred embodiments of the present invention, Figure 7 As shown, the two clamping plates 341 are perpendicular to the radius of the cross-section of the cross-flow wind wheel 100. When the two wind wheel segments 10 rotate relative to each other, the force generated by the relative rotation of the wind wheel segments 10 acts on the edge of the clamping plates 341, and the clamping plates 341 are not easily deformed, so the buckle 340 is not easily separated from the clamping hole 330, so that the connection between the buckle 340 and the clamping hole 330 is more stable, thereby improving the stability of the connection between the two wind wheel segments 10.
