[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0040] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0041] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0042] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0043] Please refer to Figures 1-5, the present utility model provides a fan fixing component 100, which is used to fixedly connect a motor 230 and an impeller 220 to improve the stability of the fan 200. Understandably, the fan 200 includes a wind guide cover 210, an impeller 220, a motor 230 and a fan fixing component 100. The fan fixing component 100 includes a bottom plate 110, a frame body 120 and a motor fixing seat 140. Both the wind guide cover 210 and the bottom plate 110 are connected to the frame body 120 to enclose a chamber 101. The motor 230 and the impeller 220 are both located in the chamber 101. The impeller 220 is located between the wind guide cover 210 and the motor 230, and the impeller 220 and the motor 230 are rotationally matched, so as to drive the impeller 220 to rotate by using the motor 230. In this embodiment, the impeller 220 is directly opposite to the wind guide cover 210 to use the wind guide cover 210 to export air to the outside.

[0044] The motor fixing seat 140 in this embodiment includes a receiving portion 141 and a connecting portion 142. The receiving portion 141 is provided with a receiving cavity 1411 to receive the motor 230. The receiving portion 141 further includes an avoidance hole 1412 communicated with the receiving cavity 1411. One end of the connecting portion 142 passes through the avoidance hole 1412 to be connected to the motor 230, and the other end is connected to the frame body 120, so as to fix the motor 230 and the impeller 220 connected to the motor 230, and improve the stability of the fan 200.

[0045] It should be noted that a clamping portion 231 is provided on the outer edge of the motor 230 in this embodiment, and a clamping groove 1421 is provided on the connecting portion 142. After one end of the connecting portion 142 passes through the avoidance hole 1412 and enters the receiving cavity 1411, the clamping portion 231 can be placed in the clamping groove 1421 so that the clamping portion 231 is clamped inside the clamping groove 1421. And, the notch of the clamping groove 1421 in this embodiment faces downward, so as to use the inner wall of the receiving cavity 1411 to block the notch of the clamping groove 1421 to limit the movement of the clamping portion 231, thereby limiting the movement of the motor 230.

[0046] The cross-sectional shape of the clamping groove 1421 in this embodiment is in the shape of "冖". In other embodiments, the clamping groove 1421 can also be set into other shapes to be clamped with the clamping portion 231 and limit the movement of the clamping portion 231.

[0047] Understandably, the connecting portion 142 and the receiving portion 141 are not fixedly connected together. After the motor 230 is started, the vibration of the motor 230 causes the connecting portion 142 to vibrate, and collisions will occur between the connecting portion 142 and the receiving portion 141, affecting the structural stability of the fan 200.

[0048] The fan fixing assembly 100 in this embodiment also includes a rubber shock absorber 130 connected to the snap-fit ​​part 231. The rubber shock absorber 130 is connected to the snap-fit ​​part 231, so that during the contact process of the motor 230, the connecting part 142 and the receiving part 141, the rubber shock absorber 130 will abut against the inner wall of the receiving cavity 1411 before the motor 230 and the receiving part 141 collide. Since the rubber shock absorber 130 is made of rubber, the contact between the rubber shock absorber 130 and the receiving cavity 1411 is a soft contact, thereby achieving the purpose of shock absorption, and can also reduce the noise generated by vibration and improve the service life of the fan 200.

[0049] Specifically, the snap-fit ​​part 231 is provided with a limiting groove to accommodate the rubber shock absorber 130 and restrict the movement of the rubber shock absorber 130 in a direction perpendicular to the axis of the motor 230, so as to prevent the rubber shock absorber 130 from disengaging after the snap-fit ​​part 231 and the snap-fit ​​groove 1421 are engaged.

[0050] It should be noted that the rubber damping component 130 in this embodiment is elastic. During the contact process between the rubber damping component 130 and the interior of the accommodating cavity 1411, the rubber damping component 130 will deform, thereby using the elastic force generated during the deformation process to achieve a buffering effect. While achieving shock absorption, it avoids the structure from colliding together, which would affect the service life, and also reduces noise.

[0051] The cross-sectional area of ​​the snap-fit ​​part 231 gradually decreases in the direction away from the axis of the motor 230 to form a guide slope 2311, thereby guiding the snap-fit ​​part 231 into the snap-fit ​​groove 1421, so that the snap-fit ​​part 231 and the snap-fit ​​groove 1421 can be snapped together.

[0052] It should be noted that, since the opening of the snap-fit ​​groove 1421 faces downward, and the snap-fit ​​groove 1421 and the snap-fit ​​part 231 are snapped together, the lower end of the rubber shock absorber 130 is located outside the snap-fit ​​part 231, so as to abut against the inner wall of the receiving cavity 1411. Thus, before the snap-fit ​​part 231 and the receiving part 141 collide, the rubber shock absorber 130 will abut against the inner wall of the receiving cavity 1411 first, so as to achieve shock absorption by using the rubber shock absorber 130.

[0053] In other embodiments, the snap-fit ​​groove 1421 may be omitted, and the rubber shock absorber 130 may be directly connected to the outer edge of the motor 230, so that the connecting part 142 directly engages with the rubber shock absorber 130, and the elastic force of the rubber shock absorber 130 is used to achieve a buffering effect, thereby achieving the purpose of shock absorption.

[0054] Further, please refer to Figures 1-5The frame 120 includes multiple uprights 121 and multiple fixed supports 122. Each fixed support 122 is connected to one end of two uprights 121 at both ends. Understandably, a fixed support 122 can be configured between any two adjacent uprights 121. The base plate 110 is connected to the other end of the uprights 121, while the air guide cover 210 is connected to the fixed support 122.

[0055] Based on the above, in this embodiment, the chamber 101 is formed by the air guide cover 210, the base plate 110, multiple columns 121 and multiple fixed brackets 122.

[0056] In this embodiment, there are multiple connecting parts 142, through holes 1221, and snap-fit ​​parts 231, with each of these components corresponding to a specific post 121. One end of each connecting part 142 passes through the corresponding through hole 1221 and snaps into the corresponding snap-fit ​​part 231, while the other end connects to the corresponding post 121. It can be understood that in this embodiment, the number of connecting parts 142, through holes 1221, snap-fit ​​parts 231, and posts 121 is equal.

[0057] It should be noted that in this embodiment, multiple through holes 1221 are arranged circumferentially around the axis of the accommodating cavity 1411, that is, multiple connecting parts 142, multiple snap-fit ​​parts 231 and multiple columns 121 are all arranged circumferentially around the axis of the accommodating cavity 1411, thereby improving the stability of the fan 200 structure.

[0058] In this embodiment, the axis of the chamber 101, the axis of the accommodating cavity 1411, and the axis of the rotating shaft on the motor 230 coincide with each other, and the impeller 220 rotates around the axis of the rotating shaft to ensure uniform gravity distribution, prevent the impeller 220 from detaching during rotation, and improve the stability of the fan 200 structure.

[0059] This embodiment also provides an air conditioning device 300, which can be an air conditioner or a heat pump to change the indoor temperature through heat exchange. The air conditioning device 300 includes a heat exchanger 310, an internal component 320, and the aforementioned fan 200. The internal component 320 is located inside the chamber 101 of the fan 200, specifically between the motor mounting base 140 and the base plate 110, while the heat exchanger 310 is located outside the chamber 101, with its adjacent sides respectively attached to the base plate 110 and the column 121; both the internal component 320 and the heat exchanger 310 are connected to the base plate 110 and the frame 120.

[0060] Specifically, in this embodiment, each fixed bracket 122 protrudes in a direction away from the axis of the chamber 101 to form a protrusion 123, and the side opposite to the side of the heat exchanger 310 that abuts against the bottom plate 110 abuts against the protrusion 123, that is, the opposite sides of the heat exchanger 310 abut against the bottom plate 110 and the protrusion 123 respectively.

[0061] Understandably, each fixed support 122 corresponds to one heat exchanger 310; therefore, this embodiment has multiple heat exchangers 310. Specifically, this embodiment has three fixed supports 122, that is, it has three heat exchangers 310, to exchange heat with the gas in the chamber 101.

[0062] It should be noted that the internal component 320 in this embodiment includes structures such as a condenser, a compressor, and pipes.

[0063] As described above, since the heat exchanger 310 is located outside the chamber 101, and the heat exchanger 310 in this embodiment is a finned heat exchange structure, in order to improve the heat exchange efficiency, it is necessary to ensure the air inlet area of ​​the fins. Therefore, the column 121 in this embodiment is provided with multiple through holes 1221 to allow air to pass through, so as to avoid the column 121 from blocking the air, so that the air drawn in by the heat exchanger 310 can enter the chamber 101 and then be discharged from the air guide cover 210 by the impeller 220.

[0064] In summary, this embodiment forms a chamber 101 by setting a base plate 110 and a frame 120. The impeller 220, motor 230, and motor mounting base 140 are all located within the chamber 101. The motor 230 is housed within the receiving cavity 1411 of the receiving portion 141. The two ends of the connecting portion 142 are respectively connected to the motor 230 and the frame 120. The motor 230 and impeller 220 are fixed by the mutual connection and cooperation between the base plate 110, the frame 120, and the motor mounting base 140, thereby improving the stability of the structure. This embodiment also connects a rubber damping element 130 to the outer edge of the motor 230, allowing the rubber damping element 130 to cooperate with the connecting portion 142 to achieve vibration damping and reduce noise.

[0065] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
