Abstract
Description
Technical Field
[0001] This utility model relates to the field of air coolers, and in particular to the U-shaped air guide frame of an air cooler. Background Technology
[0002] An air purifier, also known as an evaporative cooler, is a system that uses water evaporation to ventilate, humidify, and cool indoor air. It typically includes components such as a water tank, water pump, evaporative cooling pad, fan, air inlet, and air outlet. Air purifiers utilize the principle of natural cool air, using an internal cooling system (such as ice crystals or a water curtain) to evaporate heat from the air, thereby lowering the air temperature and achieving a cooling effect. This technology, combining natural phenomena with advanced technology, allows air purifiers to provide cool air while maintaining low energy consumption.
[0003] The air guide frame of an air cooler is a crucial component, and its design directly affects the cooler's performance and effectiveness. Current air guide frames typically consist of elongated blades, such as those arranged in a crisscross pattern (e.g.,...). Figure 20 As shown in the authorized Chinese utility model patent "Announcement No.: CN217381030U, Name: An Air Outlet Blade Installation Structure for a Cooling Fan", the air outlet blades do not rotate relative to the frame, and the user can move the air outlet blades to make them swing. However, in the above application and the prior art, the gaps between the blades are large. To prevent people from sticking their fingers in, a protective net needs to be added, which increases the production cost. Moreover, since the airflow blown out by the fan is divergent, the longitudinal and transverse blades have difficulty dispersing the airflow, resulting in a small sweeping range for the cooling fan. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of high cost and small sweeping range in the prior art, and to provide a U-shaped air guide frame for air coolers.
[0005] The present invention solves the above-mentioned technical problems through the following technical solution:
[0006] This utility model provides a U-shaped air guide frame for an air cooler, including the air cooler body.
[0007] The disassembly frame has multiple snap-fit parts on its side, and the disassembly frame is detachably connected to the air outlet of the air cooler body using the snap-fit parts.
[0008] The blade unit has a U-shaped structure, with radial blades connecting the U-shaped blades.
[0009] In this technical solution, the design of the U-shaped blades can make the gaps between the blades smaller, preventing people from sticking their fingers in, making it safer. The internal structure of the air cooler body also does not need to be fitted with wire mesh for safety, reducing costs.
[0010] Furthermore, the U-shaped blade design allows the airflow to spread in all directions, resulting in a larger and farther sweeping area. Even an adult male standing close to the fan can feel the wind from head to toe.
[0011] Preferably, the blades in the blade unit are all tilted outward around the fan center of the air cooler body.

[0014] Multiple basic U-shaped blades are provided between the base center cover plate and the disassembly frame, and the multiple basic U-shaped blades are connected to each other by multiple radial base connecting blades.
[0015] In this technical solution, the basic fan blade assembly can prevent people from entering the body of the air cooler and can expand the airflow of the air cooler body.
[0016] Preferably, the circumference of the plurality of basic U-shaped blades increases sequentially from the inside to the outside.

[0019] Multiple single-swing U-shaped blades are provided between the single-swing center cover plate and the disassembly frame, and the multiple single-swing U-shaped blades are connected to each other by multiple radial single-swing connecting blades.
[0020] In this technical solution, the airflow direction of the air cooler can be controlled by using a single swing fan blade assembly.
[0021] Preferably, a single swing mounting frame is provided on the outer side of the outermost single swing shaped blade, and the single swing center cover plate, the single swing shaped blade and the single swing mounting frame are connected by multiple single swing connecting blades.
[0022] The single swing mounting frame is rotatably connected to the inner side of the disassembly frame via a rotating connector.
[0023] In this technical solution, a rotating connector is used to enable the single swing fan blade assembly to rotate within a certain range.
[0024] Preferably, the blade unit includes a double oscillating fan blade assembly, the double oscillating fan blade assembly includes a double oscillating center cover plate, and a center fixing frame is connected to both the left and right sides of the double oscillating center cover plate. The two center fixing frames are symmetrically distributed from left to right. The end of the center fixing frame away from the double oscillating center cover plate is connected to the inner side of the double oscillating mounting frame. The double oscillating mounting frame is rotatably connected to the inner side of the disassembly frame through a rotating connector.
[0025] The area within the assembly / disassembly frame is divided into upper and lower regions by a double-swinging center cover and a center fixed frame. Multiple semi-circular blades are set in each of the two regions. The semi-circular blades in the two regions and the blades on the center fixed frame constitute a complete double-swinging semi-circular blade.
[0026] The double-swinging U-shaped blades and the double-swinging mounting frame are connected by multiple radial double-swinging connecting blades.
[0027] In this technical solution, the airflow direction of the air cooler body can be controlled by the dual swing blade assembly, which can further expand the airflow effect of the basic blade assembly and the single swing blade assembly, making the sweeping range of the air cooler body wider.
[0028] Preferably, the rotating connector includes multiple rotating columns and a support frame, wherein the multiple rotating columns are respectively connected to the outside of a single swing mounting frame or the outside of a double swing mounting frame;
[0029] The support frame has a corresponding number of fixed frames on its side. A U-shaped slot is opened on one side of each fixed frame. The surface of the rotating column is rotatably connected to the fixed frame through the U-shaped slot. The outer side of the support frame is connected to the inner side of the disassembly frame.

[0032] Preferably, the connecting pressure plate is connected to limit guard plates at the four inner corners of the disassembly frame.
[0033] In this technical solution, the rotation angle of the single-swing fan blade assembly and the double-swing fan blade assembly can be limited by using the limiting guard plate.
[0034] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.
[0035] The positive and progressive effects of this utility model are as follows:
[0036] This invention utilizes the U-shaped blade design of the blade unit to make the gaps between the blades smaller, preventing people from sticking their fingers in, thus making it safer. The internal part of the air cooler body also does not need to be equipped with wire mesh for safety, reducing costs.
[0037] Furthermore, the design of the U-shaped blades allows the wind to spread in all directions, resulting in a larger and farther sweeping area. Even an adult male standing close to the fan can feel the wind from head to toe.
[0038] Both the single-swing fan blade assembly and the double-swing fan blade assembly can rotate, thereby controlling the airflow direction of the air cooler body. This allows the air cooler body to blow upwards, downwards, concentrated airflow, and diffused airflow modes, which can expand the airflow effect of the basic fan blade assembly and further expand the sweeping range of the air cooler body.
