Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a fan assembly and an outdoor air conditioning unit having the fan assembly. Background Technology

[0002] An air conditioner consists of an indoor unit and an outdoor unit. The fan assembly of the outdoor unit is used to deliver air, but the outdoor unit will generate air delivery noise when delivering air. Excessive air delivery noise can seriously affect the physical and mental health of residents, especially the low-frequency resonance noise, which is hard to bear.

[0003] In related technologies, vibration reduction is achieved by setting vibration damping materials such as rubber or springs at the bottom of the wind turbine support or the wind turbine body. However, the vibration damping materials are difficult to limit the lateral tilt of the wind turbine body, which poses a significant safety hazard. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] The following is for reference. Figures 1-11 According to an embodiment of the present invention, the fan assembly 100 can greatly reduce the vibration transmitted from the fan mounting base 11 to the fan bracket 2. At the same time, it ensures that the piston rod 32 moves stably along the axial direction and prevents the piston rod 32 from deflecting. This ensures that the vibration damper assembly 3 can only move along the vibration direction of the fan assembly 100, thereby limiting the deflection of the fan body and improving the vibration damping effect.

[0041] like Figures 1-11 As shown, a fan assembly 100 according to an embodiment of the present invention includes: a fan body 1, a fan bracket 2, and at least one vibration damper assembly 3.

[0042] The main body of the fan 1 is mainly used to deliver air and exhaust air to achieve ventilation. The main body of the fan 1 is provided with a fan mounting base 11, which is used to support and fix the main body of the fan 1 to ensure the installation stability and reliability of the main body of the fan 1.

[0043] The fan bracket 2 is suitable for connection with the working surface. It can be connected to the working surface by means of threaded connection, adhesive connection or other connection methods, so that the fan bracket 2 can be stably installed on the working surface, ensuring that the fan bracket 2 can work stably and safely, and preventing loosening during operation that could cause noise or safety hazards.

[0044] The fan assembly 100 includes at least one vibration damper assembly 3, that is, one vibration damper assembly 3, two vibration damper assemblies 3, three vibration damper assemblies 3 or more vibration damper assemblies 3 can be provided. The vibration damper assembly 3 is used to reduce the vibration and noise generated during the operation of the fan assembly 100, especially to reduce low-frequency resonance noise to ensure that the fan assembly 100 can operate quietly and safely and protect the environment.

[0045] The vibration damper assembly 3 includes a housing 31 and a piston rod 32. The piston rod 32 is axially movably connected to the housing 31, meaning that the piston rod 32 can move axially relative to the housing 31 to achieve buffering and absorption of vibration.

[0046] One of the fan mounting base 11 and the fan bracket 2 is connected to the outer casing 31, and the other of the fan mounting base 11 and the fan bracket 2 is connected to the piston strut 32. That is, the fan mounting base 11 can be connected to the outer casing 31 and the fan bracket 2 can be connected to the piston strut 32, or the fan mounting base 11 can be connected to the piston strut 32 and the fan bracket 2 can be connected to the outer casing 31. This allows the vibration damper assembly 3 to be connected between the fan mounting base 11 and the fan bracket 2, which can absorb and reduce the vibration transmitted from the fan mounting base 11 to the fan bracket 2.

[0047] It should be noted that when the fan body 1 delivers air, the air is discharged in the direction away from the fan support 2. The reaction force of the air on the fan body 1 is opposite to the air discharge direction, that is, the direction in which the fan body 1 is closer to the fan support 2. Therefore, the vibration direction of the fan assembly 100 is the direction in which the fan body 1 is connected to the fan support 2. The vibration generated by the fan body 1 will be transmitted to the fan support 2 along the connection direction between the fan body 1 and the fan support 2. During the transmission process, it will resonate with some other components, generating low-frequency resonance sound. In the prior art, vibration reduction is achieved by setting vibration damping materials such as rubber or springs at the bottom of the fan support 2 or the fan body 1. However, vibration damping materials are difficult to limit the lateral tilt of the fan body 1, which poses a significant safety hazard.

[0048] In this application, the vibration damper assembly 3 is installed between the fan mounting base 11 and the fan bracket 2. Since one axial end of the piston rod 32 is connected to the fan mounting base 11 or the fan bracket 2, the direction of movement of the piston rod 32 is the vibration direction of the fan assembly 100. That is, the piston rod 32 can only reciprocate along the connection direction between the fan body 1 and the fan bracket 2, which is also the connection direction between the fan mounting base 11 and the fan bracket 2, to achieve a buffering and vibration reduction effect. This can greatly reduce the transmission of vibration of the fan body 1 and reduce low-frequency resonance sound from the source. At the same time, the vibration damper assembly 3 ensures that the fan body 1 can only vibrate along the connection direction between the fan body 1 and the fan bracket 2 without tilting, thus avoiding safety hazards and improving the safety of the fan assembly 100.

[0049] Furthermore, the fan assembly 100 in this embodiment can discharge air vertically upwards, vertically downwards, or laterally. When discharging air vertically upwards, the fan bracket 2 can be vertically connected to the working surface and attached to the upper surface of the working surface. When discharging air laterally, the fan bracket 2 can be horizontally connected to the working surface and attached to the side of the working surface. Figure 1 As shown, the air outlet is vertically upward, meaning the vibration direction of the fan assembly 100 is vertical. By setting a vibration damper assembly 3 that can only move in the vertical direction, the fan body 1 can only vibrate in the vertical direction without lateral deviation, which improves the safety of the fan assembly 100. At the same time, it significantly reduces the vibration transmitted downward by the fan body 1 and significantly improves the low-frequency resonance sound.

[0050] Furthermore, an elastic buffer body 4 is provided between the piston rod 32 and the outer casing 31 along the axis, and the piston rod 32 can movably abut against the side wall 312 of the outer casing.

[0051] Specifically, the elastic buffer 4 can undergo elastic deformation under pressure, absorbing vibration energy significantly through this deformation. The elastic buffer 4 is positioned between the piston rod 32 and the bottom wall 315 of the outer casing; one end of the elastic buffer 4 can be connected to the piston rod 32, and the other end can be connected to the bottom wall 315. Thus, when the piston rod 32 moves relative to the outer casing 31, it compresses or releases the elastic buffer 4 located between the piston rod 32 and the bottom wall 315. When the elastic buffer 4 is compressed by both the piston rod 32 and the bottom wall 315, it buffers the piston rod 32, absorbing vibration energy significantly and greatly reducing the vibration transmitted from the fan mounting base 11 to the fan support 2, thereby achieving vibration damping. Correspondingly, when the elastic buffer 4 is no longer compressed by the piston rod 32 and the bottom wall 315 of the outer casing, the elastic buffer 4 will expand and return to its initial shape, thus achieving vibration reduction in a cyclical manner. The elastic buffer 4 can also support the piston rod 32 to ensure that the piston rod 32 moves stably along the axial direction and prevent the piston rod 32 from deflecting. This ensures that the vibration damper assembly 3 can only move along the vibration direction of the fan assembly 100, thereby limiting the deflection of the fan body 1. The piston rod 32 can move and abut against the side wall 312 of the outer casing. That is, when the piston rod 32 moves along the axial direction, it presses against the side wall 312 of the outer casing to compress or release the elastic buffer 4, thereby ensuring the movement stability of the piston rod 32 and achieving effective vibration buffering.

[0052] Therefore, by setting an elastic buffer 4 between the piston rod 32 and the bottom wall 315 of the outer casing, the piston rod 32 is buffered and supported. This can absorb vibration energy significantly when the piston rod 32 moves, greatly reducing the vibration transmitted from the fan mounting base 11 to the fan bracket 2. At the same time, it ensures that the piston rod 32 moves stably along the axial direction and prevents the piston rod 32 from deflecting. This ensures that the vibration damper assembly 3 can only move in the vibration direction of the fan assembly 100, thereby limiting the deflection of the fan body 1 and improving the vibration damping effect.

[0053] According to the embodiment of the present invention, the fan assembly 100, by installing at least one vibration damper assembly 3 between the fan mounting base 11 and the fan bracket 2, can greatly reduce the transmission of vibration of the fan body 1, reduce low-frequency resonance noise at the source, and at the same time, ensure that the fan body 1 can only vibrate along the connection direction between the fan body 1 and the fan bracket 2 without deflection, thereby improving the safety of the fan assembly 100. By setting an elastic buffer body 4 between the piston rod 32 and the bottom wall 315 of the outer casing, the piston rod 32 is buffered and supported, and vibration energy can be absorbed significantly when the piston rod 32 moves, greatly reducing the vibration transmitted from the fan mounting base 11 to the fan bracket 2. At the same time, it ensures that the piston rod 32 moves stably along the axial direction and prevents the piston rod 32 from deflection, thereby ensuring that the vibration damper assembly 3 can only move along the vibration direction of the fan assembly 100, thereby limiting the deflection of the fan body 1 and improving the vibration reduction effect.

[0054] In some embodiments, an air pressure buffer cavity 41 is formed inside the elastic buffer body 4.

[0055] In other words, the elastic buffer 4 is hollow inside to form a pneumatic buffer chamber 41. The pneumatic buffer chamber 41 can be sealed and filled with gas. When the elastic buffer 4 is squeezed by the piston rod 32, the volume of the gas inside the pneumatic buffer chamber 41 decreases and the gas is compressed to absorb vibration energy. When the squeezing force from the piston rod 32 on the elastic buffer 4 decreases or disappears, the gas expands and its volume increases to restore its original shape, releasing the stored energy, thereby achieving vibration buffering.

[0056] Therefore, by setting up an elastic buffer body 4 with an internal air pressure buffer chamber 41, the vibration energy can be greatly absorbed, converted and dissipated through the compression and expansion of the gas in the elastic buffer body 4 during the vibration of the fan body 1, thus achieving the effect of buffering and absorbing vibration.

[0057] Furthermore, as the air pressure buffer chamber 41 is filled with gas, the stiffness of the elastic buffer body 4 increases. Thus, one end of the elastic buffer body 4 can press against the piston rod 32, and the other end can press against the bottom wall 315 of the outer shell, supporting it between the piston rod 32 and the bottom wall 315 of the outer shell. This makes the movement of the piston rod 32 more stable, preventing it from shaking or tilting. When the elastic buffer body 4 is squeezed by the piston rod 32, it deforms and makes uniform contact with the piston rod 32 and the bottom wall 315 of the outer shell, making it less prone to eccentric forces. This allows the piston rod 32 to maintain stable axial movement during vibration reduction without lateral tilting, which helps to further reduce the vibration transmission from the fan body 1 to the fan support 2.

[0058] Specifically, such as Figure 5 and Figure 11As shown, a pneumatic buffer cavity 41 is formed inside the elastic buffer body 4, such as... Figure 7 As shown in the vertical direction, the upper end face of the elastic buffer 4 is pressed against the piston rod 32, and the lower end face of the elastic buffer 4 is pressed against the bottom wall 315 of the outer shell. Thus, when the piston rod 32 moves downward, the elastic buffer 4 is compressed, and when the piston rod 32 moves upward, the elastic buffer 4 is released.

[0059] In practical design, the elastic buffer 4 can be constructed as a rubber airbag, which seals gas inside. The rubber material is easy to undergo elastic deformation and easily returns to its initial state, which is more conducive to uniform contact with the piston rod 32 and the bottom wall 315 of the outer shell when under pressure, and more stably supports the piston rod 32 and absorbs vibration energy.

[0060] Of course, the elastic buffer 4 can also be constructed as solid rubber, that is, the interior of the elastic buffer 4 is solid and not filled with gas. This makes the elastic buffer 4 more supportive and can more stably support the piston rod 32. Alternatively, the elastic buffer 4 can be constructed as a spring, with one end of the spring elastically pressing against the piston rod 32 and the other end elastically pressing against the bottom wall 315 of the outer shell. Thus, the compression and stretching of the spring can achieve the buffering and absorption of vibration, thereby enhancing the vibration reduction effect.

[0061] In some embodiments, at least two vibration damper assemblies 3 are installed between the fan bracket 2 and the fan body 1, wherein the pressure difference between the air pressure buffer chambers 41 of any two elastic buffer bodies 4 is set to be less than a set air pressure.

[0062] In other words, two, three or more vibration damper assemblies 3 can be set between the fan support 2 and the fan body 1. By setting multiple vibration damper assemblies 3, vibration can be buffered and absorbed at multiple locations, enhancing the vibration reduction effect and helping to better reduce the operating noise of the fan assembly 100.

[0063] The pressure difference between any two elastic buffer bodies 4 and their pneumatic buffer chambers 41 is set to be less than a set pressure. This set pressure can be zero or a pressure value within a certain range. By setting the pressure difference between any two elastic buffer bodies 4 and their pneumatic buffer chambers 41 to be less than the set pressure, the pressure difference between all the elastic buffer bodies 4 and their pneumatic buffer chambers 41 can be very small, i.e., the pressure values ​​are similar. Therefore, the response of each elastic buffer body 4 to the load during vibration damping tends to be synchronized, meaning that each elastic buffer body 4 uniformly disperses and absorbs vibration energy, preventing overload of a single elastic buffer body 4. This allows all elastic buffer bodies 4 to be compressed or released at the same rate, ensuring synchronous movement of each vibration damper assembly 3. Figure 1 For example, stable buffering and vibration reduction can be carried out on the transverse plane to ensure that the main body of the fan 1 moves more stably and prevent the main body of the fan 1 from local transverse deviation.

[0064] In some embodiments, a lubricant is applied between the piston rod 32 and the housing sidewall 312.

[0065] Specifically, such as Figure 7 , Figure 8 and Figure 11 As shown, the outer shell 31 can be constructed as a cylinder, and the piston part 321 can be constructed as a cylinder. The outer diameter of the piston part 321 is adapted to the inner diameter of the outer shell 31, so that the piston part 321 can move up and down against the inner peripheral wall of the outer shell side wall 312. Graphene or grease-based lubricant can be coated on the outer peripheral wall of the piston part 321, or on the inner peripheral wall of the outer shell side wall 312, so that the piston part 321 can smoothly slide up and down along the inner peripheral wall of the outer shell side wall 312, reducing friction and lowering resistance.

[0066] In some embodiments, the piston rod 32 includes a piston portion 321 and a rod portion 322. The piston portion 321 is movably disposed within the housing 31, and the rod portion 322 passes through the housing 31. One end of the rod portion 322 is connected to the piston portion 321, and the other end extends outside the housing 31.

[0067] Specifically, such as Figure 11 As shown, the piston rod 32 includes a piston part 321 and a rod part 322. The piston part 321 is installed inside the housing 31 and can move inside the housing 31. One end of the rod part 322 is fixedly connected to the piston part 321, and the other end of the rod part 322 passes through the housing 31 and extends outside the housing 31. Thus, when the rod part 322 moves, it can drive the piston part 321 to move inside the housing 31 to achieve vibration reduction.

[0068] Furthermore, the side of the piston portion 321 facing away from the support rod portion 322, together with the bottom wall 315 of the outer casing, defines the movable cavity 5, and the elastic buffer body 4 is disposed in the movable cavity 5.

[0069] Specifically, such as Figure 7 and Figure 11 As shown, the interior of the outer casing 31 is hollow, and the piston portion 321 is located on the side opposite to the support rod portion 322, i.e. Figure 7The lower side of the piston portion 321, as shown in the middle, and the inner wall of the bottom wall 315 of the outer casing together define the movable cavity 5. The movable cavity 5 can be a sealed cavity or a non-sealed cavity. The elastic buffer 4 is disposed in the movable cavity 5. The upper end face of the elastic buffer 4 is in contact with the lower side of the piston portion 321, and the lower end face of the elastic buffer 4 is in contact with the inner bottom wall of the movable cavity 5. Thus, when the fan body 1 vibrates, the vibration is transmitted to the support rod portion 322, which drives the support rod portion 322 to move axially. In turn, the support rod portion 322 drives the piston portion 321 to move up and down along the inner peripheral wall of the side wall 312 of the outer casing, thereby the piston portion 321 squeezes or releases the elastic buffer 4.

[0070] The shape of the elastic buffer 4 of this utility model is not limited and can be constructed in any shape. For example, the shape of the elastic buffer 4 can be constructed as a rectangle, cylinder, ellipse, polygon or other irregular shape.

[0071] In some embodiments, the shock absorber assembly 3 further includes an end cap 311, which is connected to the end of the housing side wall 312 away from the housing bottom wall 315. The strut portion 322 passes through the end cap 311, and the elastic buffer body 4 is elastically pressed between the piston portion 321 and the housing bottom wall 315.

[0072] Specifically, such as Figure 7 As shown, the shock absorber assembly 3 also includes an end cap 311. The end cap 311 is connected to the upper end of the housing 31, that is, the end of the housing side wall 312 away from the bottom wall 315 of the housing, to close the housing 31. A first connecting hole 3111 can be provided on the end cap 311, and a second connecting hole 3121 can be provided on the housing 31. The connector can be sequentially inserted into the first connecting hole 3111 and the second connecting hole 3121 to achieve a fixed connection between the end cap 311 and the housing 31. Thus, the end cap 311 can limit the piston rod 32 and prevent the piston rod 32 from coming out of the housing 31.

[0073] like Figure 7 As shown, a clearance hole 3112 can also be provided on the end cap 311 to allow the support rod portion 322 of the piston rod 32 to pass through the clearance hole 3112 and extend to the outside, thereby ensuring the mobility of the piston rod 32. The radial dimension of the clearance hole 3112 can be set to be larger than the outer diameter of the support rod portion 322, so that a certain gap is formed between the clearance hole 3112 and the support rod portion 322, ensuring the smooth movement of the piston rod 32.

[0074] And such as Figure 11As shown, the upper end face of the elastic buffer 4 elastically abuts against the lower side of the piston part 321, and the lower end face of the elastic buffer 4 elastically abuts against the bottom wall 315 of the outer shell. Thus, the elastic buffer 4 elastically abuts against the piston part 321 and the bottom wall 315 of the outer shell. When the piston part 321 slides up and down along the inner peripheral wall of the side wall 312 of the outer shell, it squeezes or releases the elastic buffer 4.

[0075] In some embodiments, the end cap 311 and the housing 31 are configured to be detachably connected.

[0076] In other words, the end cap 311 can be connected to other components in a detachable manner, such as by threaded connection, snap-fit ​​connection, snap-fit ​​connection, or plug-in connection. This facilitates the installation and disassembly of various structures. For example, when the elastic buffer 4 is damaged and needs to be replaced, the end cap 311 and piston rod 32 can be quickly and easily removed to take out the elastic buffer 4 for repair or replacement, which is flexible and convenient.

[0077] In some embodiments, the housing 31 is provided with at least one first connection portion for detachably connecting to one of the fan mounting base 11 and the fan bracket 2.

[0078] In other words, one, two, or more first connecting parts can be provided on the outer casing 31. The first connecting parts can be detachably connected to the fan mounting base 11. That is, the first connecting parts and the fan mounting base 11 can be connected by detachable connection methods such as snap-fit ​​connection or threaded connection, thereby realizing the connection between the vibration damper assembly 3 and the fan mounting base 11. This facilitates installation and disassembly. When the vibration damper assembly 3 or the fan mounting base 11 is damaged, the vibration damper assembly 3 or the fan mounting base 11 can be quickly and easily disassembled for repair and replacement, which is flexible and convenient.

[0079] Alternatively, the first connecting part can be detachably connected to the fan bracket 2. That is, the first connecting part and the fan bracket 2 can be connected by a detachable connection method such as snap-fit ​​connection or threaded connection, thereby realizing the connection between the vibration damper assembly 3 and the fan bracket 2. This facilitates installation and disassembly. When the vibration damper assembly 3 or the fan bracket 2 is damaged, the vibration damper assembly 3 or the fan bracket 2 can be quickly and easily disassembled for repair and replacement, which is flexible and convenient.

[0080] By setting multiple first connection parts, the fan mounting base 11 or fan bracket 2 can be connected to the vibration damper assembly 3 at multiple locations through multiple first connection parts. This can improve the connection stability and reliability between the vibration damper assembly 3 and the fan mounting base 11 or fan bracket 2, prevent the connection between the vibration damper assembly 3 and the fan mounting base 11 or fan bracket 2 from becoming loose or falling off. Moreover, if one of the first connection parts fails, the other first connection parts can still be connected normally and securely, thereby improving the working reliability of the vibration damper assembly 3.

[0081] In practical design, such as Figure 5 As shown, a first through hole 21 extending along the thickness direction can be provided on the fan bracket 2. The shape and size of the first through hole 21 are adapted to the first connecting column 313, so that the first connecting column 313 can pass smoothly through the first through hole 21 to realize the connection between the fan bracket 2 and the vibration damper assembly 3.

[0082] After the first connecting post 313 passes through the first through hole 21, the outer side of the outer shell 31 abuts against the side of the fan bracket 2 near the outer shell 31. At the same time, the first positioning member 61 abuts against the other side of the fan bracket 2, that is, the side away from the outer shell 31. Thus, the fan bracket 2 is clamped between the outer side of the outer shell 31 and the first positioning member 61, thereby achieving relative fixation between the piston rod 32 and the fan mounting base 11.

[0083] An external thread can be provided on the outer periphery of the first connecting post 313, and the first positioning member 61 can be constructed as a first positioning nut. The first positioning nut has an internal thread that matches the external thread. After the first connecting post 313 passes through the first through hole 21, the first positioning nut can be sleeved on the outside of the first connecting post 313. The first positioning nut can be tightened by thread engagement to achieve axial positioning and fixation of the first connecting post 313.

[0084] In other embodiments, the piston rod 32 is provided with at least one second connection for detachably connecting to another of the fan mounting base 11 and the fan bracket 2.

[0085] In other words, one, two, or more second connecting parts can be provided on the piston strut 32. The second connecting parts can be detachably connected to the fan mounting base 11. That is, the second connecting parts and the fan mounting base 11 can be connected by detachable connection methods such as snap-fit ​​connection or threaded connection, thereby realizing the connection between the vibration damper assembly 3 and the fan mounting base 11. This facilitates installation and disassembly. When the vibration damper assembly 3 or the fan mounting base 11 is damaged, the vibration damper assembly 3 or the fan mounting base 11 can be quickly and easily disassembled for repair and replacement, which is flexible and convenient.

[0086] Alternatively, the second connecting part can be detachably connected to the fan bracket 2. That is, the second connecting part and the fan bracket 2 can be connected by a detachable connection method such as snap-fit ​​connection or threaded connection, thereby realizing the connection between the vibration damper assembly 3 and the fan bracket 2. This facilitates installation and disassembly. When the vibration damper assembly 3 or the fan bracket 2 is damaged, the vibration damper assembly 3 or the fan bracket 2 can be quickly and easily disassembled for repair and replacement, which is flexible and convenient.

[0087] By providing multiple second connection parts, the fan mounting base 11 or fan bracket 2 can be connected to the vibration damper assembly 3 at multiple locations through multiple second connection parts. This can improve the connection stability and reliability between the vibration damper assembly 3 and the fan mounting base 11 or fan bracket 2, prevent the connection between the vibration damper assembly 3 and the fan mounting base 11 or fan bracket 2 from becoming loose or falling off. Furthermore, if one of the second connection parts fails, the other second connection parts can still be connected normally and securely, thereby improving the working reliability of the vibration damper assembly 3.

[0088] In practical design, such as Figure 5 As shown, a second through hole 111 extending along the thickness direction can be provided on the fan mounting base 11. The shape and size of the second through hole 111 are adapted to the second connecting post 323, so that the second connecting post 323 can pass smoothly through the second through hole 111 to realize the connection between the fan mounting base 11 and the vibration damper assembly 3.

[0089] like Figure 7 As shown, the radial dimension of the second connecting post 323 is smaller than the radial dimension of the piston rod 32, thus forming a limiting step surface 314 at the end of the second connecting post 323 near the piston rod 32, i.e., at the connection between the piston rod 32 and the second connecting post 323. The limiting step surface 314 is used to support the fan mounting base 11, as shown. Figure 5 As shown, after the second connecting column 323 passes through the second through hole 111, the limiting step surface 314 presses against the side of the fan mounting base 11 near the outer shell 31. At the same time, the second positioning member 62 presses against the other side of the fan mounting base 11, that is, the side away from the outer shell 31. Thus, the fan mounting base 11 is clamped between the second positioning member 62 and the limiting step surface 314, realizing the relative fixation of the piston rod 32 and the fan mounting base 11. Then, when the fan body 1 vibrates, the vibration will be transmitted to the piston rod 32, so that the piston rod 32 can move up and down in the air pressure buffer chamber 41 to buffer and absorb the vibration.

[0090] An external thread can be provided on the outer periphery of the second connecting column 323. The second positioning member 62 can be constructed as a second positioning nut. The second positioning nut has an internal thread that matches the external thread. After the second connecting column 323 passes through the second through hole 111 and the fan mounting seat 11 abuts against the limiting step surface 314, the second positioning nut can be sleeved on the outside of the second connecting column 323. The second positioning nut is tightened by thread engagement to achieve axial limiting and fixing of the second connecting column 323.

[0091] In some embodiments, the first connection portion is configured as a first connecting post 313 protruding from the housing 31 in a direction away from the piston rod 32. The first connecting post 313 passes through one of the fan mounting base 11 and the fan bracket 2 and is axially limited and fixed by the first positioning member 61.

[0092] Specifically, such as Figure 7 and Figure 11 As shown, the first connecting part is configured such that the outer casing 31 faces away from the piston rod 32, i.e. Figure 7 As shown in the upper and lower part, a first connecting post 313 protrudes from the lower part of the outer shell 31. The first connecting post 313 can be inserted into the fan mounting base 11 or the fan bracket 2. The first positioning member 61 axially limits and fixes the first connecting post 313, that is, restricts the axial movement of the first connecting post 313, so as to achieve a stable connection between the first connecting post 313 and the fan mounting base 11 or the fan bracket 2, thereby achieving a stable installation of the vibration damper assembly 3.

[0093] In other embodiments, the second connection is configured as a second connecting post 323 extending out of the housing 31. The second connecting post 323 passes through another of the fan mounting base 11 and the fan bracket 2 and is axially limited and fixed by the second positioning member 62.

[0094] Specifically, such as Figure 7 and Figure 11 As shown, the second connecting part is constructed as a second connecting post 323 extending outside the outer shell 31. The second connecting post 323 can be inserted into the fan mounting base 11 or the fan bracket 2. The second positioning member 62 axially limits and fixes the second connecting post 323, that is, restricts the axial movement of the second connecting post 323, so as to achieve a stable connection between the second connecting post 323 and the fan mounting base 11 or the fan bracket 2, thereby achieving a stable installation of the vibration damper assembly 3.

[0095] In some embodiments, at least two fan brackets 2 are provided, and the at least two fan brackets 2 are spaced apart. Each fan bracket 2 is provided with at least one vibration damper assembly 3 between itself and the fan body 1.

[0096] In other words, two, three, four, or more fan brackets 2 can be set, with at least two fan brackets 2 spaced apart to avoid interference. By setting at least two fan brackets 2, stable support can be provided for the entire fan body 1, improving the installation stability and reliability of the fan assembly 100 and making the connection between the fan assembly 100 and the working surface more secure. Each fan bracket 2 is equipped with at least one vibration damper assembly 3 between it and the fan body 1. That is, one, two, or more vibration damper assemblies 3 can be set between each fan bracket 2 and the fan body 1, thereby reducing vibration transmission between each fan body 1 and the fan bracket 2 through at least one vibration damper assembly 3, enhancing the vibration reduction effect.

[0097] Specifically, such as Figure 10 As shown, two fan brackets 2 are provided, which are connected to the working surface to improve the installation stability and reliability of the fan assembly 100. The two fan brackets 2 are distributed in parallel and spaced apart, corresponding to the position of the fan mounting base 11, so that the vibration damper assembly 3 can be accurately installed between the fan bracket 2 and the fan mounting base 11 to absorb vibration.

[0098] In some other embodiments, the fan assembly 100 further includes a fan 7 and an air guide ring 8, the fan 7 being rotatably mounted in the air guide ring 8, and the fan body 1 having a motor shaft 12 connected to the fan 7.

[0099] Specifically, such as Figure 1 and Figure 3 As shown, the fan assembly 100 also includes a fan 7 and an air guide ring 8. The air guide ring 8 is used to guide the airflow, so that the airflow moves along the direction of the axis of the air guide ring 8 until it reaches the fan 7, so that the fan 7 can better drive the airflow, form a strong airflow, and guide more gas to flow out to the outside along the axis of the air guide ring 8, thereby increasing the air volume of the fan assembly 100. Figure 1 The image shows vertical upward airflow, with the air guide ring 8 guiding the airflow upwards.

[0100] Among them, such as Figure 1 As shown, the fan 7 is rotatably mounted inside the air guide ring 8, and the fan body 1 is provided with a motor shaft 12, which is connected to the fan 7. That is to say, the fan 7 can rotate relative to the air guide ring 8 to form a strong airflow. The fan 7 is installed inside the air guide ring 8 and spaced a certain distance from the air guide ring 8 to prevent the fan 7 from hitting the air guide ring 8 when rotating, causing abnormal noise or safety hazards. The motor shaft 12 is connected to the fan 7, that is, the motor shaft 12 of the drive motor is connected to the fan 7 so that when the motor shaft 12 rotates, it can drive the fan 7 to rotate, providing power for the rotation of the fan 7.

[0101] This application reduces low-frequency resonance noise at its source by installing the vibration damper assembly 3 between the fan mounting base 11 and the fan bracket 2. Simultaneously, the vibration damper assembly 3 ensures that the fan body 1 can only vibrate along the connection direction between the fan body 1 and the fan bracket 2 without tilting. Figure 1 As shown, this design ensures that the fan body 1 and fan 7 can only vibrate vertically without tilting, preventing the fan 7 from tilting and contacting the air guide ring 8, thus improving the safety of the fan assembly 100. Furthermore, by setting an elastic buffer 4 between the piston rod 32 and the bottom wall 315 of the outer casing, the piston rod 32 is buffered and supported, which can absorb vibration energy significantly when the piston rod 32 moves, further reducing the vibration transmitted from the fan mounting base 11 to the fan bracket 2. At the same time, it ensures that the piston rod 32 moves stably along the axial direction, preventing the piston rod 32 from tilting, thus ensuring that the vibration damper assembly 3 can only move in the vibration direction of the fan assembly 100, thereby further improving the vibration damping effect and limiting the tilting of the fan body 1.

[0102] This utility model also proposes an outdoor unit for an air conditioner.

[0103] The outdoor unit of the air conditioner according to the present utility model includes the fan assembly 100 of any of the above embodiments.

[0104] According to the embodiment of the present utility model, by setting the above-mentioned fan assembly 100, the operating noise of the air conditioner outdoor unit is significantly reduced, and the operating safety and stability of the air conditioner outdoor unit are improved.
