Description

Technical Field

[0001] This utility model belongs to the field of air circulation technology, and in particular relates to an air circulation fan installation structure. Background Technology

[0002] Air circulators are primarily used for indoor air circulation to ensure a more even distribution of indoor air temperature. They can also be used as regular fans.

[0003] An air circulator fan mainly consists of a drive motor, a turbine fan, a baffle grille, and a cylindrical outer casing. Unlike ordinary fans, air circulator fans can direct airflow in a spiral pattern, creating a spiral column of air as the blades circulate. The airflow from an air circulator fan travels a longer distance and has good directionality.

[0004] Generally, one factor affecting the distance air travels in an air circulation fan is the effective length of the air duct; typically, the longer the air duct, the greater the distance the air travels.

[0005] Chinese invention publication CN103541915A discloses a circulating fan structure, comprising: a power element as a power source for driving axial fan blades; an axial fan blade is provided on the spindle of the aforementioned power element, the curvature of the outermost periphery of the aforementioned axial fan blade corresponds to the curvature of the inner guide wall of the guide element, so as to increase the output air volume and output distance; the guide element is provided with an inner guide wall, and a certain distance is generated between the outermost periphery of the aforementioned axial fan blade and the inner guide wall of the guide element, thereby concentrating and guiding the direction of airflow, reducing resistance, increasing airflow volume, and extending the output distance, thereby improving the effect of indoor airflow circulation and temperature regulation.

[0006] The aforementioned patent document describes incorporating a flow-guiding element within the fan housing. This element increases the effective length of the air duct, thereby increasing the airflow output distance. The flow-guiding element, fan blades, and drive motor are arranged sequentially, further increasing the overall length and volume. Additionally, the control circuitry for controlling the fan needs to be mounted on the base or elsewhere. Utility Model Content

[0007] The purpose of this utility model is to provide an air circulator fan installation structure that makes the length of the air circulator fan smaller and the structure more compact.

[0008] To achieve the above objectives, this utility model provides an air circulator fan mounting structure, including a casing, a motor, and fan blades. The casing includes an air inlet and an air outlet. A mounting cylinder is disposed inside the casing. A connecting rib and a wire-passing groove are provided between the mounting cylinder and the inner sidewall of the casing. One end of the wire-passing groove communicates with the interior of the casing, and the other end passes through the outer sidewall of the casing. The mounting cylinder and the inner sidewall of the casing form an annular air duct. A mounting plate is provided at the end of the mounting cylinder away from the air outlet. The mounting plate and the mounting cylinder form a cavity. The mounting plate has a mounting cavity recessed into the cavity, and the mounting cavity has a notch that passes through the wire-passing groove. The motor is mounted in the mounting cavity, and the motor's main shaft faces the air inlet. The fan blades are disposed on the motor's main shaft and located at the air inlet end of the annular air duct.

[0009] Furthermore, a support frame is provided inside the mounting cavity, the motor is fixedly connected to the support frame, a heat dissipation gap is provided between the motor and the inner wall of the mounting cavity, and a through hole is provided on the bottom wall of the mounting cavity.

[0010] Furthermore, the fan blade includes a sleeve and blades distributed on the outside of the sleeve, the sleeve is connected to the main shaft, and the outer diameter of the sleeve is smaller than the aperture of the mounting cavity.

[0011] Furthermore, the opening of the mounting cavity is also provided with a conical guide sleeve, the large end of which extends into the inner ring of the annular air duct, and the small end extends into the sleeve, and the minimum inner diameter of the conical guide sleeve is greater than the outer diameter of the sleeve.

[0012] Furthermore, the cylindrical shell includes an air intake shell and an air blower shell, with the air intake shell spliced ​​to the end of the air blower shell; the mounting cylinder is disposed inside the air blower shell, and the fan blade is located inside the air intake shell.

[0013] Furthermore, the air circulator fan mounting structure also includes a front grille cover, which includes a central plate and an annular mesh. The annular mesh is distributed around the outer periphery of the central plate, and the central plate seals the opening of the cavity.

[0014] The air circulator fan mounting structure provided in this embodiment of the utility model has at least the following technical effects:

[0015] 1. An installation cylinder is installed inside the casing. A connecting rib and a wire-passing groove are provided between the installation cylinder and the inner wall of the casing, forming an annular air duct. An installation plate is located at the end of the installation cylinder furthest from the air outlet. The installation plate and the installation cylinder form a cavity, with a recessed mounting chamber that passes through the wire-passing groove. The motor is installed inside the mounting chamber, with its main shaft facing the air inlet. The fan blades are mounted on the motor's main shaft at the air inlet end of the annular air duct. Therefore, the effective length of the annular air duct is ensured, thereby guaranteeing wind speed and force. Since the motor is installed inside the casing, this air circulator fan installation structure ensures the effective length of the air duct without requiring additional casing or fan housing.

[0016] 2. The mounting plate and the mounting cylinder form a cavity. Therefore, by installing components such as control circuits into the cavity, the effective installation space of the mounting cylinder forming an annular air duct can be fully utilized, making the overall structure more compact.

[0028] In one embodiment of the air circulator fan of this utility model, please refer to... Figure 1 The air circulator fan in this embodiment includes a mounting structure, which comprises a housing 100, a motor 200, and fan blades 300. Please refer to [reference needed] for details. Figures 2 to 6The cylindrical shell 100 includes an air inlet 101 and an air outlet 102. An installation cylinder 110 is provided inside the cylindrical shell 100. A connecting rib 120 and a wire groove 121 are provided between the installation cylinder 110 and the inner side wall of the cylindrical shell 100. One end of the wire groove 121 communicates with the interior of the cylindrical shell 100, and the other end passes through the outer side wall of the cylindrical shell 100. The installation cylinder 110 and the inner side wall of the cylindrical shell 100 form an annular air duct 103. A mounting plate 111 is provided at the end of the mounting cylinder 110 away from the air outlet 102. The mounting plate 111 and the mounting cylinder 110 form a cavity 112. The mounting plate 111 has a mounting cavity 113 recessed into the cavity 112. The mounting cavity 113 has a notch for the through-hole wire groove 121. The motor 200 is installed in the mounting cavity 113, with the main shaft of the motor 200 facing the air inlet 101. The fan blade 300 is mounted on the main shaft of the motor 200 and located at the air inlet end of the annular air duct 103. The wires used to power the motor 200 can be passed through the through-hole wire groove 121 and connected to the motor 200.

[0029] In the air circulator fan mounting structure of the above embodiment, since the fan blades 300 are located at the air inlet end of the annular air duct 103, the entire annular air duct 103 becomes an effective air duct. This ensures the effective length of the annular air duct 103, thereby ensuring the speed and pressure of the airflow blowing out of the annular air duct 103. The mounting cavity 113 within the mounting plate 111 at the end of the mounting cylinder 110 is used to mount the motor 200. Therefore, the motor 200 is located in front of the fan blades 300 and within the mounting cylinder 110. Thus, the installation of the motor 200 does not increase the overall length, making the overall structure more compact. Furthermore, the mounting plate 111 and the mounting cylinder 110 form a cavity 112. Therefore, by mounting components such as the control circuit into the cavity, the effective mounting space of the mounting cylinder 110 forming the annular air duct 103 can be fully utilized, resulting in a more compact overall structure.

[0030] Furthermore, refer to Figures 2 to 6 The mounting cavity 113 contains a support frame 114, and the motor 200 is fixedly connected to the support frame 114. A heat dissipation gap is also provided between the motor 200 and the inner wall of the mounting cavity 113, and a through hole 115 is provided on the bottom wall of the mounting cavity 113. In this embodiment, part of the airflow generated by the fan blades 300 can enter the heat dissipation gap, thereby cooling the motor 200 and its internal electronic components, preventing the motor 200 from overheating.

[0031] Furthermore, refer to Figure 2 and Figure 4 The fan blade 300 includes a sleeve 310 and blades 320 distributed on the outside of the sleeve 310. The sleeve 310 is connected to the main shaft, and the outer diameter of the sleeve 310 is smaller than the aperture of the mounting cavity 113. Therefore, the airflow generated by the rotation of the blades 320 can be sent into the gap.

[0032] Furthermore, refer toFigure 2 and Figure 4 The inlet of the mounting cavity 113 is also provided with a conical guide sleeve 140. The large end of the conical guide sleeve 140 extends into the inner ring of the annular air duct 103, and the small end extends into the sleeve 310. The minimum inner diameter of the conical guide sleeve 140 is larger than the outer diameter of the sleeve 310. Therefore, the airflow generated by the high-speed rotation of the fan blade 300 can enter the annular air duct 103 along the conical guide sleeve 140, thereby achieving the function of guiding the airflow.

[0033] Furthermore, refer to Figure 3 The cylinder shell 100 includes a suction cylinder shell 150 and a blower shell 160. The suction cylinder shell 150 is spliced ​​to the end of the blower shell 160. The mounting cylinder 110 is located inside the blower shell 160, and the fan blade 300 is located inside the suction cylinder shell 150.

[0034] Furthermore, refer to Figure 1 The air circulator fan mounting structure also includes a front grille 400, which comprises a central plate 401 and an annular mesh 402. The annular mesh 402 is distributed around the outer periphery of the central plate 401, and the central plate 401 seals the opening of the cavity 112. This provides protection for the electronic components inside the cavity 112.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
