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. Therefore, they should not be construed as limitations on this utility model.

[0043] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0044] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0045] Reference Figure 1 and Figure 4 As shown in the figure, a heat pump device 1000 provided by this utility model embodiment includes a housing 100, a heat pump assembly, a water circuit assembly 600, and an air duct assembly 200. The housing 100 has a cavity, and the heat pump assembly, water circuit assembly 600, electrical control assembly 700, and air duct assembly 200 are installed in the cavity. The heat pump assembly includes a compressor 500, a first heat exchanger 300, a second heat exchanger 400, and a throttling device. The first heat exchanger 300 is located in the middle of the cavity and is vertically arranged along the height of the housing 100, dividing the cavity of the housing 100 into an air inlet cavity 130 and an air outlet cavity 140. The compressor 500, the second heat exchanger 400, the throttling device, and the water circuit assembly 600 are all disposed in the air inlet cavity 130. When the airflow enters the air outlet cavity 140 from the air inlet cavity 130, it passes through the first evaporator for heat exchange. The air duct assembly 200 is disposed in the air outlet cavity 140.

[0046] In some embodiments, the first heat exchanger 300 is an evaporator, and the second heat exchanger 400 is a plate heat exchanger. The plate heat exchanger includes a refrigerant flow path and a water flow path. The evaporator, the refrigerant flow path of the plate heat exchanger, the throttling device, and the compressor 500 are connected to form a refrigerant circulation loop for refrigerant circulation. The water circuit assembly 600 includes a water pump, an inlet pipe, an outlet pipe, and a valve body. The inlet pipe and the outlet pipe are respectively connected to the water flow path. The water pump can be installed on either the inlet pipe or the outlet pipe to form a water supply path.

[0047] Reference Figure 1 As shown, the top of the housing 100 is provided with an air inlet 110 and an exhaust outlet 120. The air inlet 110 is connected to the air inlet cavity 130, and the exhaust outlet 120 is connected to the air outlet cavity 140. The air duct assembly 200 includes a fan 230. The fan 230 is used to draw outdoor air into the air inlet cavity 130 through the air inlet 110 and blow it toward the evaporator. After the air exchanges heat with the evaporator, it enters the air duct and is discharged through the exhaust outlet 120.

[0048] During operation, the refrigerant output from compressor 500 passes through the plate heat exchanger, where it exchanges heat with water via the refrigerant flow path. After throttling, it enters the evaporator, where it exchanges heat with outdoor air before returning to compressor 500 for the next cycle. A water pump drives chilled water into the water flow path of the plate heat exchanger, allowing the water to exchange heat with the refrigerant. Using the outdoor air as a heat source, heat is extracted through the heat exchange process to produce hot water.

[0049] The heat pump device 1000 of this utility model embodiment can provide hot water through the outlet pipe for supplying domestic hot water and heating hot water. Alternatively, the outlet pipe can be connected to a water tank to store the hot water for user use.

[0050] The above is an example of the heat pump equipment 1000. The following is a specific example illustrating the structure of the air duct assembly 200 in the heat pump equipment 1000.

[0051] Reference Figure 1 As shown, the air duct assembly 200 includes an air duct housing 210 and a fan 230. The air duct housing 210 is specifically a volute housing, which has an air duct inside. An air inlet (not shown in the attached figure) is provided on one side of the volute housing along its axial direction, and an air outlet 211 is provided on the upper side of the volute housing. The air inlet and the air outlet 211 are respectively connected to the air duct.

[0052] In this embodiment, the air duct assembly 200 further includes a bracket 220. The volute is vertically mounted on the bracket 220. The fan 230 is connected to the bracket 220. The air outlet 211 is upward-facing. The bracket 220 is connected to the side of the volute facing away from the air inlet. When the air duct assembly 200 is installed in the air outlet cavity 140, the air inlet faces the evaporator. The evaporator is located between the air inlet 110 and the air outlet, and the air outlet 211 communicates with the air outlet.

[0053] In this embodiment, the volute is made of polyurethane foam insulation material, which has a low thermal conductivity and can provide insulation. The bracket 220 is made of metal, which can be a sheet metal part processed from a metal plate, giving the bracket 220 sufficient strength to stably support the fan 230 and the volute. The hardness of the metal material is greater than that of the foam part, so the bracket 220 protects the volute.

[0054] Understandably, when the heat pump equipment 1000 is used in low-temperature environments, the fan 230 will draw cold outdoor air into the air duct during operation. The temperature outside the air duct is close to the indoor ambient temperature. Since the volute plays a role in heat insulation, it can effectively reduce the heat transfer of the air duct and make it less likely for condensation to form on the volute.

[0055] Of course, the material of the volute is not limited to foam material. In some embodiments, the volute can also be made of insulation materials such as vacuum insulation panels. Furthermore, the duct shell 210 is not limited to a volute; it can also be an axial flow duct component or other forms of duct structure. In other embodiments, a metal volute is used, and the fan 230 can be directly mounted on the volute, with the volute connected to the housing 100 without the need for an additional support structure 220.

[0056] Reference Figure 2 and Figure 3As shown, a guide rail is provided inside the housing 100. The guide rail is located inside the air outlet cavity 140 and connected to the side plate of the housing 100. The guide rail is positioned with its opening facing inwards towards the air outlet cavity 140. The bracket 220 is provided with a guide part, which is a guide structure that matches the guide rail. Specifically, it can be a guide edge, guide block, or other structures. The bracket 220 is slidably connected to the guide rail through the guide part. After the air duct assembly 200 is installed, it can be moved into or out of the air outlet cavity 140 along the guide rail from the opening, facilitating maintenance of the fan 230. It should be noted that after the air duct assembly 200 is moved into the air outlet cavity 140, the bracket 220 can be fixed to the housing 100 by screws or snap-fit, achieving the positioning purpose of the air duct assembly 200.

[0057] When the fan 230 needs to be inspected, after opening the panel of the housing 100, the screws can be removed to move the air duct assembly 200 out of the air outlet 140 along the guide rail, so that the air duct assembly 200 can be quickly inspected and the air duct can be cleaned.

[0058] Reference Figure 1 As shown, the bracket 220 has guide portions at both ends along the first direction and reinforcing portions 226 at both ends along the second direction. The guide portions are used to connect with the guide rails of the housing 100, and the reinforcing portions 226 are used to strengthen the structure of the bracket 220. The bracket 220 is a metal support plate, specifically a sheet metal part stamped from a metal sheet. The support plate is connected to one side of the volute and is arranged along the height direction of the volute so that the support plate can cover the side of the volute.

[0059] In the embodiments, Figure 1 The vertical direction of the volute shown is the first direction, and the front-to-back direction is the second direction. The support plate is located on the left side of the volute, the air inlet is located on the right side of the volute, and the air outlet 211 is located on the upper side of the volute. The guide portions at the upper and lower ends extend along the front-to-back direction of the volute.

[0060] Reference Figure 2 and Figure 3 As shown, a first guide rail 150 and a second guide rail 160 are provided inside the housing 100. The first guide rail 150 is located on the upper side of the air outlet cavity 140, also known as the upper guide rail, and the second guide rail 160 is located on the lower side of the air outlet cavity 140, also known as the lower guide rail. The first guide rail 150 and the second guide rail 160 extend along the front-rear direction of the housing 100, respectively. The guide portion at the upper end of the bracket 220 is the first guide portion 201, which is slidably connected to the first guide rail 150. The guide portion at the lower end of the bracket 220 is the second guide portion 202, which is slidably connected to the second guide rail 160, so that the bracket 220 can move into or out of the air outlet cavity 140 along the front-rear direction of the housing 100, resulting in higher stability.

[0061] Considering that both the bracket 220 and the guide rail are made of sheet metal, if the guide part directly contacts the guide rail after the air duct assembly 200 is assembled with the guide rail, the vibration generated by the motor will be transmitted to the guide rail through the guide part, which can easily cause metal resonance, resulting in abnormal noise and increasing the noise generated by the heat pump equipment 1000.

[0062] In this embodiment of the utility model, both the guide rail and the guide part are metal parts, ensuring sufficient strength to support the air duct assembly 200. Furthermore, a first shock absorber 240 is added between the guide rail and the guide part. The first shock absorber 240 is provided between the contact surfaces of the guide rail and the guide part, and the first shock absorber 240 can play a role in shock absorption and buffering.

[0063] Understandably, after the duct assembly 200 is assembled, the guide rail supports the guide section, allowing the duct assembly 200 to be stably placed within the air outlet cavity 140. When the heat pump equipment 1000 is running, the fan 230 operates, and the vibration generated by its motor is transmitted outward along the bracket 220. The first damping component 240 absorbs the mechanical vibration energy generated by the motor, blocking the rigid contact transmission path between the guide section and the guide rail, transforming the rigid contact between metal components into elastic contact, reducing the outward propagation of vibration energy, and thus eliminating abnormal noise caused by the resonance of the metal structure. In addition, when the duct assembly 200 moves along the guide rail, the guide section moves relative to the guide rail, and the first damping component 240 absorbs the vibration impact, reducing noise generation. At the same time, the first damping component 240 does not affect the normal pull-out operation of the duct assembly 200, balancing equipment reliability and maintenance convenience.

[0064] Since the first damping member 240 is located between the guide rail and the guide section, it can be mounted on the guide section, meaning the first damping member 240 is connected to the bracket 220, allowing it to move with the guide section while maintaining contact with the guide rail. Alternatively, the first damping member 240 can also be mounted on the guide rail, allowing the guide section to move relative to it while maintaining contact with the guide section, thus effectively damping and cushioning the shock.

[0065] Specifically, the first shock absorber 240 can be made of rubber, silicone, or other elastic composite materials, possessing properties such as shock absorption, wear resistance, and corrosion resistance. Taking a rubber first shock absorber 240 as an example, the first shock absorber 240 is a rubber component, which can be in the form of a block, strip, etc. The rubber component can be fixed to the guide part or guide rail by means of adhesive, fastening, etc. The rubber component absorbs vibration energy through elastic deformation, achieving the function of shock absorption and buffering.

[0066] In some embodiments, at least one first damping member 240 is disposed between the first guide portion 201 and the first guide rail 150. The number of first damping members 240 can be one, two, three, or more. For example, two first damping members 240 are disposed between the first guide portion 201 and the first guide rail 150 and connected to the first guide portion 201. The two first damping members 240 are arranged at intervals along the extension direction of the first guide rail 150 and can both contact the first guide rail 150. Similarly, at least one first damping member 240 is disposed between the second guide portion 202 and the second guide rail 160, and the specific number can also be one, two, three, or more. In this way, the first guide portion 201 and the first guide rail 150 absorb vibrations through the first damping member 240, and the second guide portion 202 and the second guide rail 160 absorb vibrations through the first damping member 240, thereby reducing the transmission of vibration energy to the first guide rail 150 and the second guide rail 160.

[0067] Reference Figure 1 , Figure 2 and Figure 3 As shown, the first guide rail 150 is configured as a first guide groove 151, the second guide rail 160 is configured as a second guide groove 161, the first guide portion 201 is a first guide bar 221 that matches the first guide groove 151, and the second guide portion 202 is a second guide portion 202 that matches the second guide groove 161. The opening of the first guide groove 151 faces upwards, and the opening of the second guide groove 161 faces downwards. The first guide groove 151 and the second guide groove 161 are positioned opposite each other. The first guide bar 221 is slidably connected within the first guide groove 151, and the second guide bar 222 is slidably connected within the second guide groove 161, thus limiting the movement of the air duct assembly 200 along the first guide groove 151 and the second guide groove 161.

[0068] Specifically, the first guide groove 151 and the second guide groove 161 are elongated grooves. The first guide strip 221 is formed by bending the upper edge of the support plate, and the second guide strip 222 is formed by bending the lower edge of the support plate. Both the first guide strip 221 and the second guide strip 222 have a flanged structure. It is understood that the gap between the first guide strip 221 and the sidewall of the first guide groove 151 has at least one first damping element 240, and the gap between the second guide strip 222 and the sidewall of the second guide groove 161 also has at least one first damping element 240.

[0069] Reference Figure 4 and Figure 5As shown, taking the first guide strip 221 and the first guide groove 151 as an example, the first damping member 240 is fixedly connected to the first guide strip 221. The first damping member 240 protrudes from the surface of the first guide strip 221. When the first guide strip 221 slides along the first guide groove 151, the first damping member 240 abuts against the side wall of the first guide groove 151, that is, the surface of the first damping member 240 contacts the side wall of the first guide groove 151, thereby separating the first guide strip 221 from the first guide groove 151 and achieving the purpose of blocking the vibration transmission path.

[0070] Understandably, by designing the guide rail with a guide groove and configuring the guide part as a guide bar that matches the guide groove, a gap is formed when the guide bar slides in the guide groove. This gap provides installation space for the first shock absorber 240. By fixing the first shock absorber 240 to one side of the guide bar and forming an abutment relationship between the first shock absorber 240 and the side wall of the guide groove, the metal guide bar and the guide groove do not directly contact each other. Instead, vibration is buffered and transmitted through elastic material. This retains the guiding function of the metal guide rail and absorbs the vibration energy generated by the operation of the fan 230 through the first shock absorber 240 in the gap, effectively reducing the generation of abnormal noise.

[0071] The guide groove can be a recessed structure made of metal, specifically formed by stamping, used to accommodate the guide strip and restrict its sliding trajectory. The guide strip can be a metal protrusion matching the shape of the guide groove, specifically formed by bending, used to drive the air duct assembly 200 to move along the guide rail. The aforementioned gap refers to the clearance reserved between the guide strip and the sidewall of the guide groove, specifically controlled within the range of 0.5 mm to 3 mm, used to accommodate the first shock absorber 240 and allow for assembly tolerances.

[0072] Reference Figure 3 As shown, the first guide groove 151 and the second guide groove 161 each include a groove body. The groove body has a port at one end near the opening. The groove body includes a bottom plate and two side plates, which are connected to opposite sides of the bottom plate. In some embodiments, the groove body is formed by bending sheet metal, i.e., the bottom plate and the side plates are an integral structure. The side plates are bent at the port position to form a guide bevel 170, which is inclined towards the port. The guide bevel 170 guides the guide portion to insert into the port and then into the groove body.

[0073] In some embodiments, one of the two side plates is provided with a guide bevel 170, so as to Figure 3 The second guide groove 161 is used as an example, and the left side plate of the second guide groove 161 is provided with a guide bevel 170. In other embodiments, both side plates may be provided with guide bevels 170 respectively, and the two guide bevels 170 are arranged opposite each other, which makes it easier for the guide part to be inserted into the port.

[0074] It should be noted that the support plate is a metal plate, and the first guide strip 221 and the second guide strip 222 are formed on the edge of the metal plate by a stamping process. In some embodiments, the first guide strip 221 and the second guide strip 222 can extend in a direction away from the volute, and the openings of the first guide groove 151 and the second guide groove 161 are oriented towards the support plate. The bending angle of the first guide strip 221 and the second guide strip 222 can be adjusted according to the opening direction of the two guide grooves to ensure that the guide strips at the upper and lower ends can be inserted into the corresponding guide grooves.

[0075] Reference Figure 1 and Figure 3 As shown, the bracket 220 is also provided with a third guide bar 223, which is arranged along the height direction of the bracket 220 and located on the rear side of the bracket 220. Specifically, the rear edge of the support plate is bent to form the third guide bar 223, which is located between the first guide bar 221 and the second guide bar 222 and extends along the height direction of the volute. Moreover, the inner side of the housing 100 is provided with a positioning groove 180 that matches the third guide bar 223. The positioning groove 180 is close to the back plate of the housing 100 and extends along the height direction of the housing 100.

[0076] Reference Figure 4 and Figure 6 As shown, when the air duct assembly 200 moves into the housing 100 along the guide rail and is installed in place, the third guide bar 223 can be inserted into the positioning groove 180 for positioning, making the connection between the bracket 220 and the housing 100 more stable, and the air duct assembly 200 is less likely to shake, thus playing a positioning role.

[0077] In this embodiment, the third guide strip 223 is provided with a second shock absorber 250, and the third guide strip 223 is also provided with a mounting hole 224. The second shock absorber 250 is fixedly connected in the mounting hole 224 of the third guide strip 223. When the air duct assembly 200 moves into the cavity, the third guide strip 223 enters the positioning groove 180, and the second shock absorber 250 abuts against the side wall of the positioning groove 180. In some embodiments, the second shock absorber 250 and the first shock absorber 240 have the same structure and are made of the same material, that is, the second shock absorber 250 has a shock absorption and buffering function. The second shock absorber 250 can absorb the mechanical vibration energy generated by the motor during operation, block the rigid contact transmission path between the third guide strip 223 and the positioning groove 180, reduce the outward propagation of vibration energy, thereby effectively eliminating abnormal noise caused by the resonance of the metal structure and reducing the noise generated by the heat pump equipment 1000.

[0078] This embodiment of the invention can significantly reduce the metal collision noise when the air duct assembly 200 moves, reduce the transmission of vibration from the fan 230 to the housing 100, and at the same time maintain the stability and smooth sliding of the guide rail structure.

[0079] Considering that the support plate serves as the supporting structure for the fan 230, and that the support plate is only connected to the housing 100 via the guide section, the connection strength requirement is relatively high. Therefore, in this embodiment of the invention, the structures of the first guide strip 221, the second guide strip 222, and the third guide strip 223 are reinforced.

[0080] Specifically, refer to Figure 7 As shown, the edge of the support plate is bent to form a first guide strip 221, a second guide strip 222, and a third guide strip 223. Each bend forms a stepped surface, and multiple reinforcing ribs 225 are provided on the stepped surface. The multiple reinforcing ribs 225 are spaced apart along the length of the stepped surface, providing additional lateral support through the stepped surface, so that the load can be distributed more evenly on each guide strip, the stress distribution is more uniform, and the overall rigidity is enhanced, making the support plate less prone to deformation, thereby enhancing the load-bearing capacity and durability of the structure. Furthermore, the reinforcing ribs 225 enhance the structural strength of the stepped surface, further improving the ability of the stepped surface to resist deformation.

[0081] Reference Figure 7 As shown, the reinforcing portions 226 at both ends of the bracket 220 are located on the front and rear sides of the volute, respectively, and are connected to the volute. The front reinforcing portion 226 is a first connecting plate, and the rear reinforcing portion 226 is a second connecting plate. The first and second connecting plates, together with the support plate, form a U-shaped bracket 220 structure, enclosing a mounting cavity. The volute is installed within the mounting cavity, with its air inlet facing away from the support plate. The first and second connecting plates enhance the connection strength between the bracket 220 and the volute, providing better support for the volute. The first and second connecting plates are connected to the volute via clips, screws, or other means.

[0082] Reference Figure 9 As shown, in some embodiments, the first damping member 240 includes a connecting portion 241 and an abutting portion 242, which are connected. The connecting portion 241 is used to connect with a guide strip, which can be a first guide strip 221 or a second guide strip 222. The connecting portion 241 can specifically be implemented using a cylindrical or rectangular column structure, and its function is to stably install the first damping member 240 at a preset position on the guide strip.

[0083] The abutment portion 242 is used to contact the guide groove and generate elastic deformation. Specifically, it can be implemented using a conical, trapezoidal, or wedge-shaped structure. The cross-sectional area of ​​the abutment portion 242 gradually decreases along the direction from the connecting portion 241 to the abutment portion 242. This gradual decrease in cross-sectional area means that, in a cross-section perpendicular to the sliding direction, the abutment portion 242 exhibits a decreasing trend in size from the end closer to the connecting portion 241 to the end farther away from the connecting portion 241, for example, by forming a conical inclined surface. This design of a gradually decreasing cross-sectional area of ​​the abutment portion 242 reduces the contact area between the first damping member 240 and the guide groove, thereby reducing friction and lowering the resistance to the guide strip sliding along the guide groove.

[0084] Furthermore, the tapered cross-section design of the contact portion 242 enables the contact portion 242 to form an adaptive deformation gradient when under pressure. By absorbing vibration energy through deformation, it maintains close contact between the first damping member 240 and the metal part, and reduces the pressure per unit area through multi-dimensional expansion in the deformation direction, thereby significantly extending the service life of the first damping member 240.

[0085] Reference Figure 8 As shown, in some embodiments, the first guide strip 221 and the second guide strip 222 are respectively provided with mounting holes 224, the connecting part 241 is connected to the mounting hole 224, and the abutting part 242 forms surface contact with the side of the guide groove. Taking the first guide strip 221 and the first guide groove 151 as an example, when the air duct assembly 200 moves, the gap between the first guide strip 221 and the first guide groove 151 is filled by the first shock absorber 240, which avoids rigid collision between the metal guide rail and the guide strip, and effectively eliminates the generation of collision noise.

[0086] In this embodiment, the maximum cross-sectional area of ​​the abutment portion 242 is larger than the area of ​​the mounting hole 224. One end of the connecting portion 241 passes through the mounting hole 224 and abuts against one side wall of the guide groove, while the abutment portion 242 abuts against the other side wall of the guide groove. The mounting hole 224 can be understood as a through-hole structure on the guide strip used to fix the connecting portion 241. Specifically, it can be implemented as a circular or rectangular hole, with its diameter forming an interference fit with the outer diameter of the connecting portion 241 to ensure that the connecting portion 241 is fixed within the mounting hole 224.

[0087] The maximum cross-sectional area of ​​the abutment portion 242 is the cross-sectional area of ​​the end of the abutment portion 242 closest to the connecting portion 241. When the maximum cross-sectional area of ​​the abutment portion 242 is greater than the area of ​​the mounting hole 224, the abutment portion 242 cannot pass through the mounting hole 224 and is confined to one side of the guide strip, abutting against the side wall of the guide groove. Since the connecting portion 241 protrudes from the surface of the guide strip after passing through the mounting hole 224, the protruding part of the connecting portion 241 abuts against the other side wall of the guide groove. In other words, both ends of the first damping member 240 abut against the opposite side walls of the guide groove, effectively separating the guide strip from the guide groove.

[0088] Reference Figure 9 As shown, in some embodiments, the abutment portion 242 has a first abutment surface 2421 and abutment surface 2422 on the side opposite to the connecting portion 241. The first abutment surface 2421 and the second abutment surface 2422 are arranged along the extension direction of the guide groove, and the first abutment surface 2421 and the second abutment surface 2422 are connected and form an included angle between them. Both the first abutment surface 2421 and the second abutment surface 2422 are planes, and the included angle formed by the first abutment surface 2421 and the second abutment surface 2422 refers to the angle formed by the intersection of the two planes in a non-parallel manner, which can be specifically achieved using a V-shaped or wedge-shaped structure.

[0089] Understandably, the connection between the first abutment surface 2421 and the second abutment surface 2422 has a small cross-sectional area. When the guide strip moves relative to the guide groove, the connection between the first abutment surface 2421 and the second abutment surface 2422 contacts the side wall of the guide groove, effectively reducing the contact area between the first damping member 240 and the guide groove, thereby reducing friction and lowering the resistance of the guide strip sliding along the guide groove. Since the first abutment surface 2421 and the second abutment surface 2422 are arranged along the extension direction of the guide groove, when the abutment part 242 is deformed by pressure, the first abutment surface 2421 or the second abutment surface 2422 can slide along the side wall of the guide groove, keeping the first damping member 240 in contact with the guide part, ensuring that the guide strip is separated from the guide groove, making the sliding more stable, and playing an effective role in shock absorption and buffering.

[0090] Reference Figure 9 As shown, in this embodiment, the first abutment surface 2421 and the second abutment surface 2422 extend toward both sides of the first shock absorber 240, forming a flange 2423. The flange 2423 protrudes from the outer wall of the connecting portion 241. Figure 9The cross-sectional shape of the abutment portion 242 is roughly triangular. The flange 2423 can be understood as an edge structure extending from the first abutment surface 2421 and the second abutment surface 2422, and can be achieved through injection molding or compression molding. The flange 2423 increases the cross-sectional size of the abutment portion 242, and the cross-sectional area of ​​the abutment portion 242 is largest at the flange 2423; the maximum cross-sectional area of ​​the abutment portion 242 is larger than the area of ​​the mounting hole 224.

[0091] The flange 2423 can be a ring-shaped protrusion formed along the circumference of the connecting portion 241. The thickness of the flange 2423 along the radial direction of the connecting portion 241 can be set in the range of 2 mm to 4 mm to increase the contact area with the guide strip and distribute the pressure load. The first abutment surface 2421 and the second abutment surface 2422 refer to the inclined plane structure that contacts the side wall of the guide groove, and can specifically adopt an inclination angle in the range of 15° to 45°.

[0092] Reference Figure 5 As shown, taking the first guide bar 221 and the first guide groove 151 as examples, one end of the connecting part 241 passes through the mounting hole 224 on the first guide bar 221, and the abutting part 242 is limited to one side of the first guide bar 221 by the flange 2423. The connecting part 241 and the mounting hole 224 can be fixed by interference fit, so that the first shock absorber 240 is fixedly connected to the first guide bar 221.

[0093] When the first guide bar 221 is placed in the first guide groove 151, the end of the connecting part 241 away from the abutting part 242 abuts against one side wall of the first guide groove 151. The first abutting surface 2421 and the second abutting surface 2422 are connected to form a V-shaped abutting surface. The V-shaped abutting surface abuts against the other side wall of the first guide groove 151, effectively blocking the vibration transmission path.

[0094] Understandably, the flange 2423 extends outward to form a support surface, and the first damping member 240 forms an elastic clamp between the two side walls. Vibrations generated during the operation of the fan 230 are transmitted to the guide strip through the duct shell 210. The first damping member 240 absorbs vibration energy through the elastic deformation of the connecting portion 241 and the abutting portion 242, preventing direct collision between the metal guide rail and the guide strip. When the flange 2423 structure is used, the first abutting surface 2421 and the second abutting surface 2422 contact the side walls of the guide groove, forming multi-point support and further dispersing the vibration load.

[0095] Of course, in other embodiments, when the first shock absorber 240 is connected to the guide groove, the connecting part 241 is connected to the side wall of the guide groove, and the abutting part 242 abuts against the guide strip. For specific connection structures, please refer to the connection method of the above embodiments.

[0096] It should be noted that the second shock absorber 250 in the embodiment is made of rubber, silicone or other elastic composite materials, and has the characteristics of shock absorption, wear resistance and corrosion resistance. Specifically, it can have the same structure as the first shock absorber 240, that is, the second shock absorber 250 includes a connecting part 241 and an abutting part 242, which can be referred to in the above embodiment as the structure of the first shock absorber 240.

[0097] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
