[0008] As a further step of this solution, the reducer and servo motor are supported by an assembly bracket at the bottom, which is mounted on the top right side of the assembly frame. The outer end of the drive shaft is supported by a bearing bracket, which is suspended on the inclined surface of the bottom wall of the elbow cylinder.

[0009] As a further step of this solution, an assembly balloon is fixedly provided in the center of the inclined surface at the bottom of the elbow cylinder. The upper part of the assembly balloon is integrally formed with the bottom of the elbow cylinder, and the lower part of the assembly balloon is assembled with the bottom of the elbow cylinder by bolts. The drive shaft and the upper drive shaft are filled with ring washers at the insertion points of the assembly balloon. The two sets of ring washers are distributed and movably sleeved on the outer walls of the drive shaft and the upper drive shaft, and the outer walls of the ring washers are fixed at the through holes of the assembly balloon.

[0010] As a further step of this solution, the blower chamber is supported by internal vertical brackets on both sides, and the elbow cylinder is also supported by an inner elbow frame.

Subsequently, a reducer and a servo motor drive the drive shaft to rotate, simultaneously rotating the upper drive shaft, thereby driving the blower disc and the upper fan to rotate for dual air intake and exhaust. This combination of the blower disc and upper fan, with the upper fan rotating in the opposite direction to the wind, generates high-speed kinetic energy in the intake air. The inertial centrifugal vortex of the blower disc creates a negative pressure in the middle of the impeller assembly, enhancing the intake air pressure and air density of the front impeller. Under pressure, the air is continuously drawn in, improving the fan efficiency. This design enhances the convenience and practicality of high-efficiency and energy-saving fans.

[0016] This utility model, by providing a support base and a support bearing, facilitates the support of the elbow cylinder. Subsequently, with the insertion and assembly of the blower chamber, the angle of the blower chamber and the upper channel can be easily adjusted according to the use, making assembly and use more convenient. Furthermore, the flared design at both the top and bottom makes it more convenient and efficient to use. Through this design, the convenience and practicality of the high-efficiency energy-saving fan are improved. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 One embodiment provided by this utility model:

[0026] A high-efficiency energy-saving fan includes an assembly frame 100. A support base 101 is mounted at the center of the top of the assembly frame 100. A blower chamber 110 is disposed between two sets of support bases 101. A blower disc 120 is installed inside the blower chamber 110. A drive shaft 130 is fixed inside the blower disc 120. Elbow cylinders 140 are fitted at both ends of the blower chamber 110. The outer wall of the elbow cylinder 140 near the blower chamber 110 is inserted into the support base 101 through a support bearing 102. An upper channel 150 is connected and assembled above the elbow cylinder 140. An upper fan 160 is mounted inside the upper part of the 150. An upper drive shaft 170 is fixed inside the upper fan 160. The lower end of the upper drive shaft 170 and the side end of the drive shaft 130 are both inserted through bearings into the outer wall of the inclined surface of the elbow cylinder 140. A bevel gear 171 and a bevel gear 172 are respectively fixed at the lower end of the upper drive shaft 170 and the side end of the drive shaft 130. The bevel gear 171 and the bevel gear 172 mesh with each other. A reducer 180 is connected to the outer right end of the drive shaft 130 through a coupling 181. A servo motor 182 is mounted at the input end of the reducer 180.

[0027] As described in more detail in this embodiment, the reducer 180 and servo motor 182 are supported by mounting brackets 183 at their bottom. The mounting brackets 183 are mounted on the top right side of the mounting frame 100. The outer end of the drive shaft 130 is supported by a bearing bracket 132, which is suspended on the inclined surface of the bottom wall of the elbow cylinder 140. This facilitates auxiliary drive and allows for synchronous drive of the two sets of impellers, saving power and improving efficiency. An assembly ball bearing 145 is fixed in the center of the inclined surface at the bottom of the elbow cylinder 140. The upper part of the assembly ball bearing 145 is connected to the bottom of the elbow cylinder 140. The assembly is integrated, and the lower part of the mounting balloon 145 is bolted to the bottom of the elbow cylinder 140. The drive shaft 130 and the upper drive shaft 170 are filled with ring washers 146 at the insertion points of the mounting balloon 145. The two sets of ring washers 146 are distributed and movably sleeved on the outer walls of the drive shaft 130 and the upper drive shaft 170, and the outer walls of the ring washers 146 are fixed at the through holes of the mounting balloon 145. This facilitates the guidance of air in and out of the blower chamber 110 and the upper channel 150, as well as the assembly at the intersection of the upper drive shaft 170 and the drive shaft 130, making subsequent use more convenient.

[0028] As described in more detail in this embodiment, the blower chamber 110 is supported by inner vertical brackets 112 on both sides, and the elbow cylinder 140 is also supported by an inner elbow frame 144. The upper channel 150 is supported by an upper horizontal bracket 151. The inner vertical bracket 112 is supported by a seated bearing 113 at its center. The seated bearing 113 is fitted onto the outer wall of the drive shaft 130, and the drive shaft 130 is inserted through the center of the inner elbow frame 144. The upper horizontal bracket 151, like the inner vertical bracket 112, is used to support the upper drive shaft 170, thereby facilitating stable support for the drive shaft 130 and the upper drive shaft 170, and also facilitating the support of the elbow cylinder 140. 0. The support of the upper channel 150 and the inner wall of the blower chamber 110 makes subsequent operation and use more stable. The elbow cylinder 140 is integrally fixed with a side retaining ring 141 on the side near the blower chamber 110. The side retaining ring 141 is sleeved on the outer wall of the blower chamber 110, and a sealing gasket 143 is fixed inside the side retaining ring 141. A nested retaining ring 142 is integrally provided on the outer side of the side retaining ring 141. The nested retaining ring 142 is sleeved on the outer wall of the blower chamber 110, and a nested bearing 111 is assembled between the nested retaining ring 142 and the outer wall of the blower chamber 110. This facilitates a strong seal without hindering rotation, making operation and use more convenient.

[0029] As described in more detail in this embodiment, the blower disc 120 is symmetrically provided with edge fan blades 121 on both sides, and the edge fan blades 121 are uniformly assembled at a 45-degree angle. An assembly inner sleeve 122 is integrally fixed in the center of the blower disc 120. A reinforcing rib 123 is supported between the outer wall of the assembly inner sleeve 122 and the side of the blower disc 120. An inner locking post 131 corresponding to the assembly inner sleeve 122 is integrally fixed in the middle of the drive shaft 130. The inner locking post 131 and the assembly inner sleeve 122 are fastened together by screws. The cross-section of the inner wall of the inner locking post 131 and the assembly inner sleeve 122 is hexagonal, which facilitates the assembly of the blower disc 120. At the same time, the assembly of the blower disc 120 and the drive shaft 130 also facilitates subsequent disassembly and maintenance.

[0030] As described in more detail in this embodiment, a lower channel 114 is integrally provided on the outer wall of the blower chamber 110. A lower flared opening 115 is integrally fixed at the end of the lower channel 114. An upper flared opening 152 is integrally provided at the upper end of the upper channel 150. An upper cover net 153 is provided on the outside of the upper flared opening 152. A pull ring 192 is integrally provided at the joint between the upper flared opening 152 and the upper channel 150. A chain rope 191 is attached to the side of the pull ring 192. A lower support plate 195 is fixed on the side of the assembly frame 100. A vertical rod 190 is inserted inside the lower support plate 195. A support ring 193 is fixed at the upper end of the vertical rod 190. The chain rope 191 passes through the support ring 193 and is connected to a lower clamp 194. The lower clamp 194 is assembled on the lower part of the outer wall of the vertical rod 190. This facilitates auxiliary limiting and pulling support when adjusting the angle of the upper channel 150, and also facilitates the filtering of foreign objects at the top of the upper channel 150 to prevent foreign objects from entering.

[0031] Working Principle: During assembly and use, when the power is turned on, the servo motor 182 is driven to rotate, outputting stable power through the reducer 180. This power then drives the drive shaft 130 to rotate, simultaneously rotating the blower disc 120. At the same time, bevel gears 171 and 172 drive the upper drive shaft 170 to rotate, thus synchronously driving the upper fan 160 to rotate. This allows the upper fan 160 and the blower disc 120 to easily cooperate to form a front and rear impeller assembly. With the cooperation of the upper channel 150, the elbow 140, and the blower chamber 110, the upper fan 160 rotates against the wind, generating high-speed kinetic energy in the intake air. The inertial centrifugal vortex of the blower disc 120 creates a negative pressure in the center of the impeller assembly. The increased air pressure and air density at the front impeller allow for continuous gas intake under pressure, improving fan efficiency. The lower channel 114, lower flare 115, and upper flare 152 facilitate more convenient and efficient air intake and exhaust. Supported by the support base 101 and support bearing 102, the elbow 140 and upper channel 150 can be easily rotated and adjusted. Subsequently, the vertical rod 190 and chain rope 191 work together, with the lower clamp 194 providing a limiting assembly for pulling support, ensuring the adjustable angle. Simultaneously, the nested retaining ring 142 and nested bearing 111 facilitate the angle adjustment of the lower channel 114, making operation more convenient. This concludes the operation.

Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
