Description

Technical Field

[0001] The invention relates to the technical field of cooling fans, and in particular to a turning device and a cooling fan. Background Art

[0002] Evaporative cooling fan (also known as "air conditioning fan") is a system that uses the principle of water evaporation to ventilate, humidify and cool indoor air. It generally includes upper water tank, lower water tank, water pump, wet curtain, fan, air inlet, air outlet and other components. When the air conditioning fan is working, the air in the environment is drawn into the air conditioning fan. When the air flows through the porous and moist wet curtain, a large amount of water on the surface of the wet curtain evaporates, and the heat reflected by the temperature in the air is converted into evaporative heat dissipation, thereby reducing the temperature of the air itself. The air conditioning fan introduces the cold air cooled by the wet curtain into the room, thereby achieving a cooling effect.

[0003] The wetting process of the wet curtain of the cold fan is as follows: water flows into the wet curtain through the water hole arranged at the upper end of the wet curtain, thereby wetting it. In addition, since the cold fan of the prior art ensures the effect of continuous cooling, the water hole is always in an open state, thereby ensuring that the wet curtain is always in a wet state.

[0004] However, when reasons such as the need to replace the wet curtain arise, the wet curtain needs to be removed from the cooling fan. At this time, due to the absence of the wet curtain, the water flowing out of the drain hole will directly hit the bottom of the cooling fan, thereby splashing water droplets and generating loud noise, resulting in a poor user experience. Summary of the invention

[0005] The purpose of the present application is to provide a flipping device and a cold fan to solve the technical problem in the cold fan in the prior art that after the wet curtain is taken out, the water flowing out of the water hole will directly hit the bottom of the cold fan, thereby splashing water droplets and generating a lot of noise.

[0010] Optionally, below the flipping part, the driving part includes: a block end and a rack end vertically connected by a connecting shaft, the block end is parallel to the wet curtain installation direction and is movably connected in the wet curtain installation groove, and the rack end is perpendicular to the wet curtain installation direction and is movably connected to the outer side of the side wall of the wet curtain installation groove.

[0011] Optionally, a U-shaped groove is provided on the side wall where the wet curtain installation groove is connected to the driving part, and the connecting shaft is movably installed in the U-shaped groove.

[0012] Optionally, an end of the rack away from the connecting shaft is fixedly connected to a driving spring.

[0013] Optionally, the flipping device further includes: at least one transmission gear, one end of the at least one transmission gear is meshed with the rack end, and the other end is rotationally connected to the flipping part via a rotating shaft.

[0014] Optionally, the number of transmission gears is three, the first transmission gear is rotationally connected to the flip part via a rotating shaft, the third transmission gear is meshed with the rack end, and both ends of the second transmission gear are respectively meshed with the first transmission gear and the third transmission gear.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0036] like Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in the first aspect, the present application provides a flip device, which is movably installed below the water hole 1 of the cooling fan, and the water hole 1 is a plurality of water holes, and the flip device includes:

[0037] The flip part 2 is arranged below the drain hole 1. A stop bar 4 matching the drain hole 1 is arranged on the wall of the flip part 2 facing the drain hole 1. In order to ensure the blocking effect of the stop bar on the drain hole, preferably, the shape of one end of the stop bar 4 close to the drain hole 1 is adapted to the shape of the drain hole 1.

[0038] The driving part 5 is transmission-connected with the flip part 2 , and when the driving part 5 drives the flip part 2 to rotate, the gear bar 4 is driven to make a reciprocating motion in a direction of blocking or away from the drain hole 1 to open or close the drain hole 1 .

[0039] When using this solution, after the wet curtain 15 is taken out, the driving unit 5 will drive the flip part 2 to rotate clockwise, thereby driving the gear bar 4 provided on the flip part 2 to move in the direction of blocking the drain hole 1, thereby achieving the closure of the drain hole 1, avoiding the noise caused by the falling water flow, and improving the user experience; on the contrary, when the wet curtain 15 is installed, the driving unit 5 will drive the flip part 2 to rotate counterclockwise, thereby driving the gear bar 4 provided on the flip part 2 to move in the direction away from the drain hole 1, thereby achieving the opening of the drain hole 1, ensuring that the water flow out of the drain hole 1 can flow smoothly to the wet curtain 15, thereby ensuring the wetting effect of the wet curtain 15.

[0040] According to one embodiment of the present invention, in order to further ensure the blocking effect of the stop bar on the drain hole, as Figure 1 As shown, the height of the stop bar 4 is adapted to the distance from the drain hole to the turning portion.

[0041] According to one embodiment of the present invention, in order to ensure that all drain holes 1 are closed or opened, as shown in FIG. Figure 1 and Figure 5 As shown, the number of the blocking bars 4 is the same as the number of the drain holes 1 .

[0042] According to one embodiment of the present invention, in order to further ensure the control of all the drain holes 1 by the turning device, as shown in FIG. Figure 1 and Figure 5 As shown, the length of the turning portion 2 is adapted to the length of the arrangement of the plurality of drain holes 1 .

[0043] According to one embodiment of the present invention, Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, the driving part 5 is arranged below the flip part 2, and the driving part 5 includes: a block end 7 and a rack end 8 vertically connected by a connecting shaft 6, the block end 7 is parallel to the installation direction of the wet curtain 15, and is movably connected to the wet curtain installation groove 9, and the rack end 8 is perpendicular to the installation direction of the wet curtain 15, and is movably connected to the outer side of the side wall of the wet curtain installation groove 9.

[0044] According to one embodiment of the present invention, in order to facilitate the movement of the driving unit 5, as shown in FIG. Figure 2 As shown, a U-shaped slot 10 is provided on the side wall where the wet curtain mounting slot 9 is connected to the driving part 5, and the connecting shaft 6 is movably installed in the U-shaped slot 10. When the block end 7 or the rack end 8 moves, the connecting shaft 6 will reciprocate along the bottom of the U-shaped slot 10 toward the opening.

[0045] According to one embodiment of the present invention, in order to improve the automatic resetting capability of the driving unit 5, as shown in FIG. Figure 2 and Figure 3 As shown, one end of the rack end 8 away from the connecting shaft 6 is fixedly connected to a driving spring 11 .

[0046] According to one embodiment of the present invention, the driving part 5 and the flipping part 2 are connected by transmission through at least one transmission gear, one end of the at least one transmission gear is meshed with the rack end 8, and the other end is rotatably connected to the flipping part 2 through the rotating shaft 3; when in use, the rack end 8 will drive the transmission gear to rotate when making a linear motion, thereby driving the flipping part 2 to flip.

[0047] According to one embodiment of the present invention, in order to improve the transmission capability of the driving part to the flipping part, as Figure 1 , Figure 2 and Figure 3As shown, three transmission gears are provided, the first transmission gear 12 is rotationally connected to the flip part 2 through the rotating shaft 3, the third transmission gear 14 is meshed with the rack end 8, and the two ends of the second transmission gear 13 are respectively meshed with the first transmission gear 12 and the third transmission gear 14.

[0048] When in use, first install the wet curtain 15 in the wet curtain installation groove 9. At this time, since the block end 7 is set in the wet curtain installation groove 9, as the wet curtain 15 is installed, the wet curtain 15 will push the block end 7 to move in the direction close to the inner wall of the wet curtain 15. Through the transmission of force, the rack end 8 is driven by the connecting shaft 6 to move in the direction of the compression drive spring 11, thereby driving the third transmission gear 14 meshing with the rack end 8 to rotate counterclockwise, and the second transmission gear 13 will rotate clockwise under the drive of the third transmission gear 14. When the water hole 1 is opened, the water flow out of the drain hole 1 can be ensured to flow smoothly to the wet curtain 15, thereby ensuring the wetting effect of the wet curtain 15.

[0049] Similarly, when the wet curtain 15 is taken out of the cooling fan, the pressure of the wet curtain 15 on the driving part 5 disappears, and the driving spring 11 will drive the rack end 8 to move away from the driving spring 11 under the action of its own resilience, thereby driving the third transmission gear 14 meshing with the rack end 8 to rotate clockwise, and the second transmission gear 13 will rotate counterclockwise under the drive of the third transmission gear 14, and the first driving gear will rotate clockwise under the action of the second transmission gear 13. Rotational connection, so when the first transmission gear 12 rotates clockwise, the flip part 2 is synchronously driven to rotate clockwise, thereby driving the gear bar 4 arranged on the flip part 2 to move in the direction of blocking the drain hole 1, thereby realizing the closure of the drain hole 1, avoiding the noise caused by the falling water flow, and improving the user experience; at the same time, the block end 7 is driven by the connecting shaft 6 to move in the direction away from the inner wall of the wet curtain installation groove 9, thereby resetting the block end 7 to the initial state, preparing for the next opening of the drain hole 1, improving the automation of the flip device, and improving the operating efficiency.
