[0074] In the prior art, the noise of the duct air conditioner is loud, which affects the user experience. Therefore, it is necessary to install a silencer structure at the air outlet of the duct air conditioner body. In the prior art, silencer ducts are installed at the air outlet of the duct air conditioner to achieve noise reduction. However, due to the large size and weight of traditional silencer ducts, the installation and disassembly of the silencer ducts are difficult, and they are not easy to clean. In addition, the application scenarios of the silencer ducts are limited by their large size. Furthermore, since different models of duct air conditioners need to match different models of silencer ducts, the versatility of the silencer ducts is poor, which greatly increases the production and design costs of the duct air conditioners.

[0075] To this end, the embodiment of the present invention designs a silencer module 100 with an air duct 101 formed by splicing and combining multiple silencer parts 10. One or more silencer modules 100 can together form a silencer assembly 1000 for silencer arranged at the air outlet 304 of the duct machine. Since different shapes of silencer assemblies 1000 can be formed by adopting different splicing methods to form different air ducts 101, the versatility of the silencer assembly 1000 formed by splicing is greatly improved. According to different models of silencer pipes, silencer assemblies 1000 suitable for duct machines of this model can be spliced ​​out accordingly. Furthermore, for different application scenarios, silencer assemblies 1000 suitable for the scenario can also be spliced ​​out accordingly, so that the installation and disassembly of the silencer assembly 1000 are not limited by the scenario. Furthermore, since the silencer assembly 1000 can be broken up into silencer parts 10 after disassembly, it is more convenient to clean the air duct 101 formed by the silencer assembly 1000.

[0076] Reference below Figure 1-Figure 20 A sound dampening assembly 1000 is described according to an embodiment of the present invention.

[0077] like Figure 1-Figure 20 As shown, the silencer assembly 1000 includes at least one silencer module 100, and the silencer module 100 defines an air duct 101. According to the size of the installation space corresponding to the silencer assembly 1000 and the different models of the silencer pipe, the silencer modules 100 with different lengths, widths, and heights can be designed accordingly, or the number of the silencer modules 100 in the silencer assembly 1000 can be adjusted accordingly. Among them, the number of the silencer modules 100 in the silencer assembly 1000 affects the length of the air duct 101 defined by the silencer assembly 1000 as a whole, and affects the silencer performance of the silencer assembly 1000.

[0078] Furthermore, the silencer module 100 includes a plurality of silencer components 10, that is, the silencer module 100 is composed of a plurality of silencer components 10, and the silencer components 10 can be connected together by splicing and combining, and the plurality of silencer components 10 after assembly can form various shapes, and finally the silencer components 10 spliced ​​and combined together can form a silencer module 100 that defines an air duct 101.

[0079] Since different shapes of silencer assemblies 1000 can be formed by different splicing methods, different air ducts 101 can be formed. Therefore, the versatility of the silencer assemblies 1000 formed by splicing is greatly improved. According to different models of silencer pipes, silencer assemblies 1000 suitable for the model of duct machines can be spliced ​​out. For different application scenarios, silencer assemblies 1000 suitable for the scenarios can also be spliced ​​out, so that the installation and disassembly of the silencer assemblies 1000 are not limited by the scenarios. Furthermore, since the silencer assemblies 1000 can be easily disassembled into individual silencer parts 10 after disassembly, it is more convenient to clean and repair the air duct 101.

[0080] Each muffler 10 defines a muffler cavity and a muffler hole 1001 connected to the muffler cavity is provided on one side of the muffler 10 facing the air duct 101. The muffler hole 1001 can absorb noise, and the noise can be reduced in the muffler cavity. Airflow can pass through the air duct 101. Due to the muffler performance of the muffler 10 itself, during the process of airflow passing through the air duct 101, noise can be absorbed by the muffler 10, so as to achieve the muffler and noise reduction function and improve the user experience.

[0081] According to the silencer assembly 1000 of the embodiment of the present invention, the silencer assembly 1000 has good noise reduction effect, flexible assembly, strong versatility, easy installation and disassembly, and reduced production design costs.

[0082] In some embodiments, the air duct 101 defined by the silencer module 100 may be an air duct 101 with a circular cross-section. Correspondingly, the silencers 10 constituting the silencer module 100 are arranged along the circumference of the corresponding circular cross-section and are connected in sequence.

[0083] In other embodiments, the muffler 10 may be formed as a block, and the air duct 101 defined by the muffler module 100 may be an air duct 101 with a polygonal cross section, and each side of the polygon is formed by one muffler 10 or a plurality of mufflers 10 connected in sequence. Each internal angle of the polygonal cross section is ninety degrees or two hundred and seventy degrees.

[0084] In some embodiments, reference Figure 1-Figure 4 The air duct 101 defined by the silencer module 100 group is formed into an air duct 101 with a rectangular cross-section.

[0085] Specifically, the plurality of silencers 10 include: a first block 101, a second block 102 and a third block 3, wherein the first block 101 and the second block 102 are arranged relative to each other in a first direction (the AB direction as shown in the figure) to form at least a portion of two oppositely arranged side walls of the air duct 101, and at least two third blocks 3 are arranged relative to each other in a second direction (the CD direction as shown in the figure) and are located between the first block 101 and the second block 102 to form the other two oppositely arranged side walls of the air duct 101. Thus, at least one first block 101 forms a side wall on one side in the first direction, at least one second block 102 forms a side wall on the other side in the first direction, at least one third block 3 forms a side wall on one side in the second direction, and at least one third block 3 forms a side wall on the other side in the second direction. The silencer module 100 composed of the first block 101, the second block 102 and the third block 3 defines an air duct 101 extending along a third direction (the EF direction as shown in the figure), and the cross section of the air duct 101 is a rectangular cross section.

[0086] The first direction, the second direction and the third direction are perpendicular to each other.

[0087] The cross-sectional size of the air duct 101 is designed according to the size of the air outlet 304 of the air duct machine body 300. According to different models of the air duct machine, the silencer module 100 with different cross-sectional sizes of the air duct 101 can be designed. The length direction and width direction of the rectangular cross-sectional area extend along the first direction and the second direction respectively. The number of the first blocks 101 and / or the second blocks 102 and the length of the first blocks 101 in the first direction determine the length of the rectangular cross-sectional area in the first direction. The number of the third blocks 3 and the length of the third blocks 3 in the second direction determine the length of the rectangular cross-sectional area in the second direction. That is, the number of the first blocks 101, the second blocks 102 and the third blocks 3 assembled on the silencer module 100 can be adjusted according to the model of the air duct machine. Correspondingly, a silencer assembly 1000 suitable for the air duct machine of this model is assembled, and the silencer assembly 1000 has better versatility.

[0088] The length of the silencer assembly 1000 is designed according to the application scenario of the duct machine. The silencer assembly 1000 includes one or more silencer modules 100. When there are multiple silencer modules 100, the multiple silencer modules 100 are sequentially arranged in affixed manner in the third direction. The first block 101, the second block 102 and the third block 3 have the same length in the third direction, and the length is the length of the silencer module 100 in the third direction, that is, the length of the air duct 101 defined by the silencer module 100. The length of the silencer module 100 in the third direction and the number of silencer modules 100 included in the silencer assembly 1000 determine the length of the silencer assembly 1000 as a whole in the third direction. That is, the number of silencer modules 100 included in the silencer assembly 1000 can be adjusted according to the application scenario. For different application scenarios, the silencer assembly 1000 suitable for the scenario can also be spliced ​​out accordingly, so that the installation and disassembly of the silencer assembly 1000 are not limited by the scenario.

[0089] In some embodiments, the silencer module 100 includes a plurality of first blocks 101 and a second block 102, wherein the plurality of first blocks 101 are arranged and connected in the second direction to jointly form a side wall on one side of the air duct 101 in the first direction defined by the silencer module 100, and the plurality of second blocks 102 are arranged and connected in the second direction to jointly define a side wall on the other side of the air duct 101 in the first direction.

[0090] The two ends of the first block 101 are connected to the adjacent first blocks 101. There are many ways to connect the first blocks 101 to the first blocks 101. Specifically, refer to Figure 6-Figure 12In order to achieve the connection between two adjacent first blocks 101 in the second direction, the two adjacent first blocks 101 in the second direction are plug-fitted or snap-fitted, thereby not only making the connection between the two adjacent first blocks 101 more stable and ensuring the stability of the overall setting of the silencer assembly 1000, but also, on the other hand, the first blocks 101 connected together by plug-fitting or snap-fitting are more convenient to install and disassemble, which is convenient for users to disassemble and clean, thereby improving the efficiency of installation and maintenance.

[0091] Furthermore, the plug-in and snap-fit ​​connection between two adjacent first blocks 101 or second blocks 102 can reduce the use of screw connection structures, improve assembly efficiency, reduce production costs, and avoid parts falling off and affecting safety in use.

[0092] In some embodiments, in order to achieve the connection between two adjacent first blocks 101 in the second direction, two adjacent first blocks 101 in the second direction are plug-fitted.

[0093] like Figure 6 , Figure 7 and Figure 8 As shown, each first block 101 is respectively provided with a first plug-in structure 11 and a first plug-in matching structure 12 at both ends in the second direction, and the first plug-in structure 11 of one of the two adjacent first blocks 101 is plugged and matched with the first plug-in matching structure 12 of the other, that is, with the end of the first block 101 provided with the first plug-in structure 11 as the head and the end of the first block 101 provided with the first plug-in matching structure 12 as the tail, the multiple first blocks 101 are connected head to tail in the second direction to achieve the purpose of connecting the multiple first blocks 101 in sequence in the second direction.

[0094] Specifically, refer to Figure 6 , Figure 7 and Figure 8 The first plug-in structure 11 includes a plug-in block 111, and the first plug-in matching structure 12 includes a surrounding plate 121. The surrounding plate 121 defines a slot 1210. The plug-in block 111 is suitable for being plugged into the slot 1210 from the notch of the slot 1210 along the second direction, so that the inner wall of the slot 1210 can limit the plug-in block 111 to prevent the plug-in block 111 from detaching from the slot 1210, thereby ensuring the stability of the connection between the two adjacent first blocks 101.

[0095] The first plug-in structure 11 also includes a plug-in board 112, which is connected to one side of the plug-in block 111. The first plug-in matching structure 12 also includes a connecting plate 122, which is arranged at an opening on one side of the enclosure 121. The plug-in board 112 is suitable for being inserted between the enclosure 121 and the connecting plate 122 along the second direction. The plug-in board 112 can be inserted between the enclosure 121 and the connecting plate 122, thereby avoiding the corresponding direction of the silencer hole 1001 facing away from the air duct 101 during the installation of part of the first block 101, affecting the silencer performance of the silencer assembly 1000, thereby achieving a fool-proof effect.

[0096] Combination Figure 9-12 In the illustrated embodiment, each first block 101 is provided with a card hole 13 and a buckle 14 at both ends of the second direction, and the card hole 13 of one of the two adjacent first blocks 101 and the buckle 14 of the other are snap-fitted together. The cooperation between the buckle 14 and the card hole 13 can realize the connection and limiting between the two adjacent first blocks 101.

[0097] In some embodiments, the plug-in structure and the snap-in structure are simultaneously arranged on both sides of the first block 101 in the second direction. With the joint cooperation of the plug-in structure, the buckle 14 and the snap hole 13, the redundancy of the connection structure is increased, which can further ensure the stability of the connection between the two adjacent first blocks 101.

[0098] Specifically, refer to Figure 9-12 In some embodiments, each first block 101 is provided with a plurality of second plug-in structures 15 at one end in the second direction and a plurality of second plug-in matching structures 16 at the other end, and the plurality of second plug-in matching structures 16 of one of the two adjacent first blocks 101 are suitable for one-to-one plug-in matching with the plurality of second plug-in matching structures 16 of the other one along the first direction, thereby, the second plug-in matching structure 16 of one of the first blocks 101 can limit the second plug-in structure 15 of the other first block 101 on both sides of the third direction, and can also limit the second plug-in structure 15 of the other first block 101 on one side in the first direction and one side in the second direction.

[0099] The buckle 14 is provided on at least one second plug-in structure 15, and the clamping hole 13 is penetrated along the second direction and provided on the corresponding second plug-in matching structure 16. Through the cooperation between the buckle 14 and the clamping hole 13, the first block 101 can simultaneously limit the first direction and the second direction of another first block 101 connected thereto, and under the joint cooperation of the second plug-in structure 15, the second plug-in matching structure 16, the buckle 14 and the clamping hole 13, the stability of the connection between the two adjacent first blocks 101 can be ensured.

[0100] In some further embodiments, each first block 101 is provided with a plurality of third plug-in structures at one end in the second direction and a plurality of third plug-in mating structures at the other end, and the plurality of third plug-in structures of one of the two adjacent first blocks 101 are suitable for one-to-one plug-in mating with the plurality of third plug-in mating structures of the other one along the third direction. Thus, the third plug-in mating structure of one of the first blocks 101 can limit the third plug-in structure of the other first block 101 on both sides of the first direction, and can also limit the third plug-in structure of the other first block 101 on one side in the second direction and on one side in the third direction.

[0101] The buckle 14 is provided on at least one third plug-in structure, and the clamping hole 13 is penetrated along the second direction and provided on the corresponding third plug-in matching structure.

[0102] In some further embodiments, the first blocks 101 may be connected to each other by fasteners.

[0103] Specifically, Figure 6-Figure 12 As shown, the first block 101 is provided with a first connecting hole 17 and a first matching hole 18 at both ends of the second direction respectively, and the two adjacent first blocks 101 are connected by a first fastener, and the first fastener extends along the first direction and is penetrated by the first connecting hole 17 and the first matching hole 18. Through the connection and matching of the first connecting hole 17 and the first matching hole 18, the connection between the two adjacent first blocks 101 can also be achieved.

[0104] Two adjacent first blocks 101 may be connected only by plug-in fit, snap-fit ​​fit or fasteners, or may be connected by a combination of these methods.

[0105] like Figure 7 and Figure 8 As shown, the first connection hole 17 and the first matching hole 18 are respectively provided on the first plug-in structure 11 and the first plug-in matching structure 12 at both ends of the first block 101. Figure 9-12 The first connecting hole 17 and the first matching hole 18 are respectively arranged on the second plug-in structure 15 and the second plug-in matching structure 16 at both ends of the first block 101 to prevent the setting of the fastener from affecting the sealing of the internal cavity of the muffler 10.

[0106] Combination Figure 1-Figure 6In the illustrated embodiment, the first block 101 and the second block 102 have the same structure, and the connection method of two adjacent first blocks 101 is the same as the connection method of two adjacent second blocks 102. The first block 101 and the second block 102 can be completely the same structure to reduce production costs and ensure that the side wall structures on both sides of the first direction of the air duct 101 are the same, which is convenient for the coordination of multiple silencer modules 100.

[0107] Further, the two sides of the third block 3 in the first direction are respectively connected to the first block 101 and the second block 102 to ensure the stability of the silencer module 100. Specifically, the third block 3 is provided with a connection structure, and the first block 101 and / or the second block 102 are provided with a connection matching structure, and the connection structure and the connection matching structure cooperate with each other to achieve the connection between the third block 3 and the first block 101 and the second block 102, so that the first block 101, the second block 102 and the third block 3 can jointly enclose the air outlet 101.

[0108] In some embodiments, the third block 3 may be connected to the first block 101 and / or the second block 102 by fasteners, specifically, as Figure 1-Figure 6 As shown, the connection structure includes a positioning column 311 and the positioning column 311 is provided with a second connection hole 3111, the connection matching structure includes a second matching hole 191, the positioning column 311 is inserted into the second matching hole 191 and is connected by a second fastener, and the second fastener extends along the first direction and is passed through the second connection hole 3111 and the second matching hole 191 to facilitate the installation of the fastener while ensuring the connection stability between the first block 101 and / or the second block 102 and the third block 3.

[0109] According to some other embodiments of the present invention, the third block 3 may be connected to the first block 101 and / or the second block 102 by snap-fitting. Specifically, Fig.15 and Fig.16 As shown, one of the connection structure and the connection matching structure is a latching protrusion 3112 and the other is a latching groove 192, so that the connection between the third block 3 and the first block 101 and the third block 3 and the second block 102 is achieved through the latching fit between the latching protrusion 3112 and the latching groove 192. The latching fit can facilitate the installation and disassembly between the third block 3 and the first block 101 and the third block 3 and the second block 102, thereby reducing the usage rate of fasteners.

[0110] Furthermore, the silencer 10 also includes: a fourth block 4, which is arranged in the air duct 101 and has its two ends respectively connected to the first block 101 and the second block 102. The setting of the fourth block 4 can increase the inner surface area of ​​the silencer module 100, increase the contact area between the silencer block and the airflow in the air duct 101, and improve the silencer effect of the silencer module 100.

[0111] The fourth block 4 may be connected to any one or more of the first block 101 , the second block 102 or the third block 3 via fasteners. Specifically, a portion of the fourth block 4 is connected to the first block 101 and / or the second block 102 .

[0113] In some embodiments, the third matching hole 103 may be the same hole as the second matching hole 191 in the above embodiment, so as to simplify the processing steps of the silencer 10 and reduce the processing cost of the silencer 10 .

[0114] In other embodiments, the fourth block 4 can be disposed between the first block 101 and the second block 102 by bonding, or, in some other embodiments, the fourth block 4 can be directly limited by the first block 101 and the second block 102 between the first block 101 and the second block 102, without being directly connected to the first block 101 and the second block 102.

[0115] Part of the fourth block 4 is connected to the third block 3 , and two adjacent contacting third blocks 3 and fourth blocks 4 are connected via a fourth fastener extending along the second direction.

[0117] In some embodiments, the structures of the third block 3 and the fifth block 5 can be completely the same, so as to facilitate the production of the muffler 10. At this time, the positions of the fifth connection hole 32 and the fifth matching connection hole are staggered, that is, the fifth connection hole 32 and the fifth matching connection hole are respectively provided on both sides in the width direction of the muffler 10, and the fifth connection hole 32 and the fifth matching connection hole are respectively provided on both sides in the width direction of the muffler 10 at the same height.

[0118] In some embodiments, the structures of the third block 3 , the fourth block 4 and the fifth block 5 are completely identical to facilitate the production of the silencer 10 .

[0119] In some further embodiments, the width of the fourth block 4 is smaller than the width of the third block 3 to facilitate installation of the muffler module 100 .

[0120] Combination Figure 1-Figure 6 In the illustrated embodiment, the silencer assembly 1000 further includes two brackets 200 . The two brackets 200 can integrate one or more silencer modules 100 into a whole, and can install the silencer assembly 1000 as a whole at the air outlet 304 of the duct machine body 300 .

[0121] Specifically, the two brackets 200 are arranged opposite to each other in the second direction and define an installation space therebetween. The silencer module 100 is arranged in the installation space to facilitate the integration and installation of one or more silencer modules 100 .

[0122] The bracket 200 is suitable for being connected to the suspension rod 301 of the duct machine body 300, so as to utilize the suspension rod 301 on the duct machine body 300 for hoisting to realize the installation of the silencer assembly 1000, thereby reducing the production cost.

[0123] Reference Figure 6 The bracket 200 includes: a first plate 201, a second plate 202 and a third plate 203.

[0124] Specifically, the second plate 202 is arranged below the silencer module 100 to support the silencer module 100 from below. The second plate 202 of the two brackets 200 are simultaneously arranged on one side of the silencer module 100 in the third direction close to the silencer tube body to limit the silencer module 100 on one side in the third direction of the silencer module 100.

The limiting device 204 is used to limit the silencer module 100 in the installation space.

[0126] That is to say, through the limitation of the first plate 201, the second plate 202 and the third plate 203 of the two brackets 200 and the action of gravity, the silencer module 100 has one degree of freedom only on one side in the third direction, and the limiting device 204 can limit the silencer module 100 on the other side in the third direction of the silencer module 100 to ensure the stability of the setting of the silencer module 100.

[0127] Specifically, combined Figure 18-Figure 20 In the illustrated embodiment, the limiting device 204 includes: a mounting seat 401, a limiting block 402 and a reset member 403. The limiting block 402 is disposed on the mounting seat 401 and is movable along the second direction between a locking position and an unlocking position.

[0128] In the locking position, a portion of the limiting block 402 extends into the installation space to limit the silencer module 100 on the other side of the third direction of the silencer module 100 to ensure the stability of the silencer module 100.

[0129] In the unlocked position, the limiting block 402 is retracted into the space in the mounting seat 401 , so that the silencer module 100 is installed into the passage in the installation space, which facilitates the installation of the silencer module 100 .

[0130] The reset member 403 is connected to the limit block 402 and is used to drive the limit block 402 to move toward the locking position. Therefore, when the silencer module 100 is installed in place, the limit block 402 can automatically return to the locking position to limit the silencer module 100 and ensure the stability of the silencer module 100.

The limit surface 4021 is arranged toward the installation space, and the guide surface 4022 extends out of the installation space in a direction away from the limit surface 4021. During the installation of the silencer module 100, the guide surface 4022 first contacts the silencer module 100 to drive the limit block 402 to move toward the mounting seat 401 during the installation of the silencer module 100. After the silencer module 100 is installed in place, the limit surface 4021 contacts the silencer module 100 to ensure the stability of the limit block 402 in limiting the silencer module 100.

By adopting the above-mentioned silencer assembly 1000, the noise of the duct machine is reduced, the installation is more convenient, and the user experience of the duct machine is improved.

[0137] The other structures of the duct air conditioner are already in the prior art and are well known to those skilled in the art, so the other structures of the duct air conditioner will not be described in detail here.

[0138] An embodiment of the air duct machine is described below with reference to the accompanying drawings.

[0139] like Figure 1-Figure 6 As shown, the duct dryer includes: a duct dryer body 300 and a silencer assembly 1000 .

[0140] The silencer assembly 1000 defines a silencer air duct 101 . The silencer assembly 1000 is disposed at the air outlet 304 of the air duct machine body 300 , and the inlet of the silencer air duct 101 is directly opposite to and connected to the air outlet 304 .

[0141] The duct machine body 300 is hoisted by four suspension rods 301 , and the silencer assembly 1000 is connected to two of the suspension rods 301 near the air outlet 304 .

[0142] Specifically, the muffler assembly 1000 includes two muffler modules 100 and two brackets 200. The two brackets 200 are arranged opposite to each other in the second direction and define an installation space therebetween. The two muffler modules 100 are stacked in the installation space along the third direction and are limited by the brackets 200. The two brackets 200 can integrate two independent muffler modules 100 into a whole.

[0143] The bracket 200 includes: a first plate 201, a second plate 202, a third plate 203 and a limiting device 204.

A limiting device 204 is provided at one end of the third plate 203 away from the first plate 201, and at least a portion of the limiting device 204 protrudes into the installation space. The first plate 201, the second plate 202, the third plate 203 and the limiting device 204 cooperate with different sides of the silencer module 100.

[0144] Specifically, the second plate 202 is arranged below the silencer module 100 to support the silencer module 100 from below. The second plate 202 of the two brackets 200 are simultaneously arranged on one side of the silencer module 100 in the third direction close to the silencer tube body to limit the silencer module 100 on one side in the third direction of the silencer module 100. The third plate 203 of the two brackets 200 are respectively arranged on both sides of the silencer module 100 in the second direction to limit the silencer module 100.

[0145] That is to say, through the limitation of the first plate 201, the second plate 202 and the third plate 203 of the two brackets 200 and the action of gravity, the silencer module 100 has one degree of freedom only on one side in the third direction, and the limiting device 204 can limit the silencer module 100 on the other side in the third direction of the silencer module 100 to ensure the stability of the setting of the silencer module 100.

[0146] The limiting device 204 includes: a mounting seat 401, a limiting block 402 and a reset member 403. The limiting block 402 is disposed on the mounting seat 401 and is movable along the second direction between a locking position and an unlocking position.

[0147] In the locking position, a portion of the limiting block 402 extends into the installation space to limit the silencer module 100 on the other side of the third direction of the silencer module 100 to ensure the stability of the silencer module 100.

[0148] In the unlocked position, the limiting block 402 is retracted into the space in the mounting seat 401 , so that the silencer module 100 is installed into the passage in the installation space, which facilitates the installation of the silencer module 100 .

[0149] The reset member 403 is connected to the limit block 402 and is used to drive the limit block 402 to move toward the locking position. Therefore, when the silencer module 100 is installed in place, the limit block 402 can automatically return to the locking position to limit the silencer module 100 and ensure the stability of the silencer module 100.

[0150] The limit block 402 is provided with a guide protrusion, and the mounting seat 401 is provided with a guide hole. The guide protrusion cooperates with the guide hole to guide the limit block 402 during the movement of the limit block 402 along the second direction. The mounting seat 401 is provided with a spring seat, and the limit block 402 is provided with a spring mounting portion. The reset member 403 includes a spring, and the spring is respectively connected to the spring seat and the spring mounting portion.

[0151] Reference Fig.19 The limit block 402 shown includes a limit surface 4021 and a guide surface 4022 which are arranged in opposite directions. The limit surface 4021 is arranged toward the installation space, and the guide surface 4022 extends out of the installation space in a direction away from the limit surface 4021. During the installation of the silencer module 100, the guide surface 4022 first contacts the silencer module 100 to drive the limit block 402 to move toward the mounting seat 401 during the installation of the silencer module 100. After the silencer module 100 is installed in place, the limit surface 4021 contacts the silencer module 100 to ensure the stability of the limit block 402 in limiting the silencer module 100.

[0152] In summary, the first plate 201 , the second plate 202 , the third plate 203 and the limiting device 204 of the bracket 200 together realize the limiting integration of the two silencer modules 100 , thereby ensuring the stability of the setting of the silencer modules 100 .

[0153] Furthermore, the silencer assembly 1000 is disposed at the air outlet 304 of the duct machine body 300 through two brackets 200 .

[0154] The two brackets 200 are respectively arranged on both sides of the air outlet 304, and connected to the suspension rods 301 on both sides of the air outlet 304, so that the muffler assembly 1000 can be installed as a whole at the air outlet 304 of the air duct machine body 300. Among them, the end of the first plate 201 away from the second plate 202 is provided with a connecting flange 2012, and the connecting flange 2012 is provided with a through hole 20121, and the through hole 20121 is used to cooperate with the suspension rod 301 to achieve the connection between the bracket 200 and the suspension rod 301. Specifically, the suspension rod 301 is provided with an external thread, and the suspension rod 301 is also provided with a matching nut with an internal thread, and the matching nut is arranged below the connecting flange 2012 and cooperates with the connecting flange 2012.

[0156] The silencer module 100 is composed of a plurality of silencers 10, and the silencers 10 are made of meta-materials to achieve broadband sound absorption and improve the noise reduction effect of the silencer assembly 1000. Each silencer 10 defines a silencer cavity, and a silencer hole 1001 connected to the silencer cavity is provided on the side surface of the silencer 10 facing the air duct 101. The silencer hole 1001 can absorb noise, and the noise can be reduced in the silencer cavity. Airflow can pass through the air duct 101. Due to the silencer performance of the silencer 10 itself, during the process of airflow passing through the air duct 101, the noise can be absorbed by the silencer 10, so as to achieve the function of silencer and noise reduction, and improve the user experience.

[0157] The silencer 10 is formed in a square shape, and includes: a first block 101, a second block 102 and a third block 3. The first block 101 and the second block 102 have the same structure. The first block 101 and the second block 102 are arranged opposite to each other in the first direction to form two oppositely arranged side walls of the air duct 101 in the first direction. The two third blocks 3 are arranged opposite to each other in the second direction and are located between the first block 101 and the second block 102 to form two oppositely arranged side walls in the second direction of the air duct 101. The silencer module 100 composed of the first block 101, the second block 102 and the third block 3 defines the air duct 101 extending along the third direction, and the cross section of the air duct 101 is a rectangular cross section.

[0158] The cross-sectional size of the air duct 101 is designed according to the size of the air outlet 304 of the air duct machine body 300. According to different models of the air duct machine, a silencer module 100 with different cross-sectional sizes of the air duct 101 can be designed. The length direction and width direction of the rectangular cross-sectional area extend along the first direction and the second direction respectively. The number of the first block 101 and / or the second block 102 and the length of the first block 101 in the first direction determine the length of the rectangular cross-sectional area in the first direction, that is, the number of the first block 101 and the second block 102 assembled on the silencer module 100 can be adjusted according to the model of the air duct machine. Correspondingly, a silencer assembly 1000 suitable for the air duct machine of this model is assembled, and the silencer assembly 1000 has better versatility.

[0159] The silencer module 100 includes three first blocks 101, three second blocks 102 and two third blocks 3. The three first blocks 101 are arranged and connected in sequence in the second direction, the three second blocks 102 are arranged and connected in sequence in the second direction, one third block 3 is arranged between one end in the second direction of the assembly formed by connecting the first blocks 101 and the assembly formed by connecting the second blocks 102, and the other third block 3 is arranged between the other end in the second direction of the assembly formed by connecting the first blocks 101 and the assembly formed by connecting the second blocks 102.

[0160] Each first block 101 is respectively provided with a first plug-in structure 11 and a first plug-in matching structure 12 at both ends in the second direction, and the first plug-in structure 11 of one of the two adjacent first blocks 101 is plugged and matched with the first plug-in matching structure 12 of the other, that is, with the end of the first block 101 provided with the first plug-in structure 11 as the head and the end of the first block 101 provided with the first plug-in matching structure 12 as the tail, the multiple first blocks 101 are connected head to tail in the second direction, so as to achieve the purpose of connecting the multiple first blocks 101 in sequence in the second direction.

[0161] Specifically, refer to Figure 6 , Figure 7 and Figure 8 The first plug-in structure 11 includes a plug-in block 111, and the first plug-in matching structure 12 includes a surrounding plate 121. The surrounding plate 121 defines a slot 1210. The plug-in block 111 is suitable for being plugged into the slot 1210 from the notch of the slot 1210 along the second direction, so that the inner wall of the slot 1210 can limit the plug-in block 111 to prevent the plug-in block 111 from detaching from the slot 1210, thereby ensuring the stability of the connection between the two adjacent first blocks 101.

[0162] The first plug-in structure 11 also includes a plug-in board 112, which is connected to one side of the plug-in block 111. The first plug-in matching structure 12 also includes a connecting plate 122, which is arranged at an opening on one side of the enclosure 121. The plug-in board 112 is suitable for being inserted between the enclosure 121 and the connecting plate 122 along the second direction. The plug-in board 112 can be inserted between the enclosure 121 and the connecting plate 122, thereby avoiding the corresponding direction of the silencer hole 1001 facing away from the air duct 101 during the installation of part of the first block 101, affecting the silencer performance of the silencer assembly 1000, thereby achieving a fool-proof effect.

[0163] The first block 101 is provided with a first connection hole 17 and a first matching hole 18 at both ends of the second direction, respectively. The first connection hole 17 and the first matching hole 18 are respectively provided on the first plug structure 11 and the first plug matching structure 12 at both ends of the first block 101. Two adjacent first blocks 101 are connected by a first fastener, which extends along the first direction and penetrates the first connection hole 17 and the first matching hole 18. Through the connection and matching of the first connection hole 17 and the first matching hole 18, the connection between the two adjacent first blocks 101 can be further realized.

[0164] Furthermore, the first block 101 and the second block 102 have the same structure.

[0165] Specifically, Figure 1-Figure 6 As shown, the third block 3 is provided with a positioning column 311 and the positioning column 311 is provided with a second connecting hole 3111, the first block 101 and / or the second block 102 is provided with a second matching hole 191, the positioning column 311 is inserted into the second matching hole 191 and is connected by a second fastener, and the second fastener extends along the first direction and is passed through the second connecting hole 3111 and the second matching hole 191, so as to facilitate the installation of the fastener while ensuring the connection stability between the first block 101 and / or the second block 102 and the third block 3.

[0166] The silencer 10 also includes: a fourth block 4, which is arranged in the air duct 101 and has its two ends respectively connected to the first block 101 and the second block 102. The setting of the fourth block 4 can increase the inner surface area of ​​the silencer module 100, increase the contact area between the silencer block and the airflow in the air duct 101, and improve the silencer effect of the silencer module 100.

[0167] The fourth block 4 is provided with a third connecting hole 41. The fourth block 4 and the first block 101 / the second block 102 are connected by a third fastener. The third fastener extends along the first direction and passes through the third connecting hole 41 and the second matching hole 191, thereby realizing the connection between the fourth block 4 and the first block 101, and the fourth block 4 and the second block 102.

[0168] The silencer module 100 includes six fourth blocks 4. Specifically, any two fourth blocks 4 of the six fourth blocks 4 are arranged back to back to form three groups of fourth blocks 4, wherein the surface where the silencer holes 1001 are located faces the air duct 101. The middle group of the three groups of fourth blocks 4 is not connected to the first block 101 and the second block 102, but is directly limited by the first block 101 and the second block 102 between the first block 101 and the second block 102.

[0169] The muffler module 100 further includes a fifth block 5, which is disposed between the first block 101 and the second block 102, and disposed on both sides of the third block 3 in the third direction. A fifth connection hole 32 is disposed on one side of the fifth block 5 close to the third block 3 in the second direction, and fifth matching connection holes are disposed on both sides of the third block 3 in the third direction, and a fifth fastener is adapted to be inserted through the fifth connection hole 32 and the fifth matching connection hole along the second direction.

[0170] The third block 3, the fourth block 4 and the fifth block 5 have similar structures, and the structures of the third block 3 and the fifth block 5 can be completely the same, so as to facilitate the production of the silencer 10. The width of the fourth block 4 is smaller than that of the third block 3, so as to facilitate the installation of the silencer module 100.

[0171] That is, a silencer 10 may integrate the structures of the third block 3, the fourth block 4 and the fifth block 5 at the same time, and the positions of the fifth connecting hole 32 and the fifth matching connecting hole on the silencer 10 are staggered, that is, the fifth connecting hole 32 and the fifth matching connecting hole are respectively provided on both sides in the width direction of the silencer 10, and the fifth connecting hole 32 and the fifth matching connecting hole are respectively provided on both sides in the width direction of the silencer 10 at the same height.

[0172] Therefore, during the production process, only two different types of silencers 10 need to be produced to realize the processing and manufacturing of the silencer module 100 .
