[0002] For example, the volute assembly of a ducted air conditioner is generally mounted on the partition of the ducted air conditioner, and the partition supports and fixes the volute assembly. When there are multiple volute assemblies, the partition needs to withstand a large pressure from the volute, which can easily cause the partition to be damaged or the connection between the volute assembly and the partition to become loose, which is not conducive to ensuring the stability of the volute assembly in the ducted air conditioner. Summary of the invention

[0003] The problem solved by the invention is how to improve the stability of a volute assembly when it is installed in an air conditioner.

[0004] In order to solve the above problems, the present invention provides a volute assembly structure, including a partition, a volute assembly, a top cover plate, a spring-loaded assembly arranged on the volute assembly, and a fixing member arranged on the top cover plate, the partition is detachably connected to the volute assembly, the spring-loaded assembly is detachably connected to the fixing member, and the volute assembly is detachably connected to the top cover plate via the spring-loaded assembly and the fixing member.

[0005] Therefore, by providing a spring-clip assembly and a fixing piece, and the spring-clip assembly is provided on the volute assembly, and the fixing piece is provided on the top cover plate, the spring-clip assembly and the fixing piece are detachably connected to realize the detachable connection between the volute assembly and the top cover plate; in this way, when the volute assembly is provided in the fan chamber, the partition detachably connected to the volute assembly applies an upward supporting force to the volute assembly at the connection point, and the top cover plate detachably connected to the volute assembly applies an upward pulling force to the volute assembly, thereby further improving the stability of the volute assembly when installed in the duct fan, and ensuring the stability of the volute assembly when working.

[0006] Optionally, the volute assembly includes a mounting plate and a volute disposed on the mounting plate, the mounting plate is detachably connected to the partition, the volute and the spring-loaded assembly are both disposed on a side of the mounting plate away from the partition, and the spring-loaded assembly is located at both ends of the mounting plate in the length direction.

[0007] Thus, the volute assembly is detachably connected to the partition plate and the top cover plate through the mounting plate, so as to ensure the stability of the volute assembly when installed in the duct machine and facilitate the disassembly or installation between the volute assembly and the partition plate.

[0008] Optionally, the spring buckle assembly includes a mounting seat and a spring buckle arranged on the mounting seat; a limiting hole is provided on the fixing member, one end of the spring buckle is slidably connected to the mounting seat, and the other end is snap-fitted with the limiting hole.

[0009] Therefore, a limiting hole is provided on the fixing part, which is used to snap-fit ​​with the end of the spring buckle facing the top cover plate to ensure the stability of the volute assembly when connected to the top cover plate, thereby improving the stability of the volute assembly in the duct machine and making it easy to disassemble the volute assembly and the top cover plate; the end of the spring buckle away from the top cover plate is slidably connected to the mounting seat to achieve the snap-fit ​​or separation of the spring buckle and the limiting hole through the sliding of the spring buckle, which has the advantage of easy operation.

[0010] Optionally, the snap-on assembly further includes an elastic member and a button, and the button is slidably connected to the mounting seat; the snap-on includes an integrally formed sliding portion and a connecting portion, and the connecting portion is snap-fitted with the limiting hole, and the sliding portion is connected to the button at one end away from the mounting plate, and the sliding portion is connected to the elastic member at one end toward the mounting plate, and the elastic member is connected to the mounting seat or the mounting plate at one end away from the snap-on; and the button and the sliding portion are both suitable for sliding in a direction toward or away from the mounting plate.

[0011] Thus, the elastic member, the sliding part, and the button are connected in sequence from back to front, the end of the button away from the sliding part is slidably connected to the mounting seat, the end of the elastic member away from the sliding part is connected to the mounting seat or the mounting plate, and the button and the sliding part are both suitable for sliding in a direction toward or away from the mounting plate, so that the snap fit or separation of the spring buckle and the limiting hole is achieved by sliding the button and the sliding part.

[0012] Optionally, the mounting seat includes an integrally formed mounting seat body and a fixing plate, one end of the mounting seat body is integrally formed with the mounting plate, and the fixing plate is arranged at the other end of the mounting seat body; one end of the button away from the sliding part passes through the fixing plate and extends out.

[0013] Therefore, a first through hole suitable for the button to move in the front-rear direction is provided on the fixed plate, and the end of the button away from the connection with the sliding part extends forward from the fixed plate through the first through hole to facilitate the installation personnel to press the button; moreover, the mounting seat body is suitable for being rotatably connected to the rotating shaft of the wind wheel in the volute to support the wind wheel and ensure the stability of the wind wheel in the volute when rotating.

[0014] Optionally, the length of the button's end away from the sliding portion extending out of the fixing plate is greater than the sliding stroke of the snap.

[0015] Therefore, the sliding stroke of the spring buckle is the maximum distance that the spring buckle can move toward the mounting plate when the button is not pressed, so as to prevent the button from falling out of the first through hole when the installer presses the button, thereby ensuring stable operation of the spring buckle assembly.

[0016] Optionally, the top cover plate and the fixing member are respectively provided with one of a positioning convex bump and a positioning hole, and the positioning convex bump is plug-fitted into the positioning hole.

[0017] Thus, the positioning convex bump (positioning hole) on the top cover plate is plugged into and matched with the positioning hole (positioning convex bump) on the fixing member to achieve pre-positioning of the fixing member on the top cover plate, thereby facilitating setting of the fixing member on the top cover plate.

[0018] Optionally, a boss is provided on the top cover plate, and one of the positioning convex bump and the positioning hole is provided on the boss and the fixing member respectively, and the boss protrudes toward the volute.

[0019] Therefore, by setting a boss on the top cover plate to strengthen the structural strength of the top cover plate, the stability of the volute assembly when connected to the top cover plate is ensured, thereby ensuring the stability of the volute assembly when installed in the duct machine, and reducing the distance from the fixing part set on the boss to the mounting seat body, thereby facilitating the connection between the fixing part and the top cover plate at the boss.

[0020] Optionally, the boss is a rib structure, and the rib structure is formed by the top cover plate protruding toward the volute.

[0021] Thus, the rib structure is formed by the top cover plate protruding toward the volute. Compared with a boss having a ridge-like structure, a convex hull-like structure or a convex dot-like structure, the reinforcing ribs of the rib structure can save the production cost of the top cover plate.

[0022] Optionally, the rib structure forms an avoidance groove on the side of the top cover plate facing the volute, and the limiting hole is connected to the avoidance groove; when the spring buckle is snap-fitted with the limiting hole, one end of the spring buckle that is snap-fitted with the limiting hole is located in the avoidance groove.

[0023] Therefore, the boss has a U-shaped, V-shaped or ring-shaped structure, and forms an avoidance groove connected to the limiting hole on the side of the top cover plate facing the volute, so as to avoid the top cover plate interfering with the spring buckle inserted into the limiting hole, and makes one end of the spring buckle engaged with the limiting hole suitable for moving to a certain extent in the front-rear direction within the avoidance groove, so as to facilitate the assembly or disassembly of the spring buckle and the limiting hole.

[0024] Optionally, the volute assembly structure also includes a snap-on structure; the snap-on structure is arranged on the mounting plate, and a slot structure is provided at a position on the partition corresponding to the snap-on structure, and / or the snap-on structure is arranged on the partition, and a slot structure is provided at a position on the mounting plate corresponding to the snap-on structure; and the snap-on structure is snap-fitted with the slot structure.

[0043] Combination Figure 1 , Figure 2 As shown, the present invention provides a volute assembly structure, including a partition 1, a volute assembly 2, a top cover plate 3, a snap assembly 4 arranged on the volute assembly 2, and a fixing member 5 arranged on the top cover plate 3, the partition 1 is detachably connected to the volute assembly 2, the snap assembly 4 is detachably connected to the fixing member 5, and the volute assembly 2 is detachably connected to the top cover plate 3 via the snap assembly 4 and the fixing member 5.

[0044] The volute assembly structure is applied to air conditioners. This embodiment and the following text are all described by taking the volute assembly structure applied to duct air conditioners (i.e. duct air conditioners) as an example. The housing of the duct air conditioner has a top cover plate 3, a bottom plate, a left side plate and a right side plate (not shown in the figure) and other panels, which are used to enclose a receiving cavity for accommodating a heat exchanger (not shown in the figure) and volute assembly structure and other components of the duct air conditioner, so as to protect the heat exchanger and volute assembly structure and other components. The top cover plate 3 is located at Figure 1The Z axis is in the positive direction, the chassis is in the opposite direction of the Z axis, the left side panel is in the opposite direction of the Y axis, and the right side panel is in the positive direction of the Y axis. The partition 1 of the volute assembly structure is arranged in the housing of the duct machine, and is used to support the top cover plate 3 and other panels to improve the structural strength of the housing of the duct machine; and the partition 1 divides the accommodating cavity of the duct machine for accommodating components such as the heat exchanger and the volute assembly structure into a heat exchange cavity and a fan cavity. The heat exchanger of the duct machine is arranged in the heat exchange cavity, and the volute assembly 2 is arranged in the fan cavity and is detachably connected to the partition 1 to ensure the stability of the volute assembly 2 in the duct machine, and to improve the space between the volute assembly 2 and the partition 1. Convenience of disassembly or installation; the snap-on assembly 4 is arranged on the volute assembly 2, and the fixing piece 5 is arranged on the top cover plate 3. The snap-on assembly 4 and the fixing piece 5 are detachably connected to realize the detachable connection between the volute assembly 2 and the top cover plate 3, so as to facilitate the disassembly and installation between the volute assembly 2 and the top cover plate 3, and on the basis of the detachable connection between the volute assembly 2 and the partition plate 1, the stability of the volute assembly 2 when installed in the duct machine is further improved, thereby ensuring the stability of the volute assembly 2 when working.

[0045] By setting the snap-on assembly 4 and the fixing part 5, the detachable connection between the volute assembly 2 and the top cover plate 3 is realized; when the volute assembly 2 is arranged in the fan chamber, the partition 1 detachably connected to the volute assembly 2 applies an upward supporting force to the volute assembly 2 at the connection point, and the top cover plate 3 detachably connected to the volute assembly 2 applies an upward pulling force to the volute assembly 2; in this way, the stability of the volute assembly 2 when installed in the duct machine is improved, thereby ensuring the stable operation of the volute assembly 2.

[0046] Furthermore, the snap assembly 4 and the fixing member 5 are suitable for snap-fitting to realize the detachable connection between the volute assembly 2 and the top cover plate 3; for example, the snap assembly 4 is suitable for elastic deformation or has a component suitable for elastic deformation, so as to realize the snap-fitting or separation between the snap assembly 4 and the fixing member 5, thereby facilitating the installation and removal between the volute assembly 2 and the top cover plate 3. In this way, through the snap-fitting of the snap assembly 4 and the fixing member 5, on the one hand, the stability of the volute assembly 2 and the top cover plate 3 when connected through the snap assembly 4 and the fixing member 5 is ensured; on the other hand, the installation and removal process between the snap assembly 4 and the fixing member 5 is simplified, thereby reducing the difficulty of installation and removal between the volute assembly 2 and the top cover plate 3.

[0047] Optionally, combined Figure 1 , Figure 2 As shown, the volute assembly 2 includes a mounting plate 21 and a volute 22 arranged on the mounting plate 21, the mounting plate 21 is detachably connected to the partition 1, the volute 22 and the snap-fit ​​assembly 4 are both arranged on the side of the mounting plate 21 away from the partition 1, and the snap-fit ​​assembly 4 is located at both ends of the mounting plate 21 in the length direction.

[0048] The volute assembly 2 includes a mounting plate 21 and a volute 22; in the present embodiment, the mounting plate 21 and the volute 22 may be detachably connected to facilitate the separate manufacturing and forming of the mounting plate 21 and the volute 22; or the mounting plate 21 and the volute 22 may be integrally formed to ensure the structural strength of the volute assembly 2 and the convenience of disassembly or installation of the volute assembly 2 in the duct machine. The volute assembly 2 is detachably connected to the partition 1 and the top cover plate 3 through the mounting plate 21, so as to ensure the stability of the volute assembly 2 in the air duct machine and facilitate the disassembly or installation between the volute assembly 2 and the partition 1; specifically, the volute 22 and the snap-in assembly 4 are both arranged on the side of the mounting plate 21 away from the partition 1, and preferably the snap-in assembly 4 is arranged at both ends in the length direction of the mounting plate 21 to avoid the setting of the snap-in assembly 4 interfering with the connection of the wind wheels in the multiple volutes 22; the fixing member 5 is arranged on the side of the top cover plate 3 facing the volute 22, so as to facilitate the detachable connection with the snap-in assembly 4, thereby improving the convenience of disassembly or installation between the volute assembly 2 and the top cover plate 3, and through the connection between the fixing member 5 and the snap-in assembly 4, the stability of the volute assembly 2 when installed in the air duct machine is further improved.

[0049] Moreover, the convenience of disassembly and installation between the volute assembly 2 and the partition 1 and the top cover plate 3 makes it convenient to maintain, clean the volute assembly 2 or clean the heat exchanger after the volute assembly 2 is removed; specifically, when the mounting plate 21 is removed from the partition 1 and the top cover plate 3, the volute 22 arranged on the mounting plate 21 is also removed together and can be taken out from the return air outlet of the air duct machine, so as to maintain and clean the volute assembly 2 outside the air duct machine; the volute 22 is provided with an air outlet at one end facing the partition 1, and the partition 1 is provided with an opening 11 for communicating with the air outlet of the volute 22. When it is necessary to clean the heat exchanger of the air duct machine, the mounting plate 21 can be removed from the partition 1 and the top cover plate 3. The plate 21 and the volute 22 are removed from the partition 1 together, and then a water gun is extended from the opening 11 on the partition 1 into the heat exchange chamber to clean the heat exchanger located in the heat exchange chamber, thereby ensuring that the duct machine delivers fresh, high-quality cold air or warm air; on the other hand, since the duct machine is usually provided with multiple volutes 22 to ensure the air output of the duct machine, the present invention arranges a volute assembly 2 so that multiple volutes 22 are connected to the mounting plate 21, so that the multiple volutes 22 can be disassembled and installed as a whole, which facilitates the disassembly and installation of the volute 22 in the fan chamber of the duct machine, that is, improves the convenience of disassembly and installation of the volute 22.

[0050] Optionally, combined Figure 1-Figure 5 As shown, the snap assembly 4 includes a mounting seat 41 and a snap 42 arranged on the mounting seat 41; a limiting hole 51 is provided on the fixing member 5, one end of the snap 42 is slidably connected to the mounting seat 41, and the other end is snap-fitted with the limiting hole 51.

[0051] In this embodiment, the mounting seat 41 and the mounting plate 21 may be integrally formed to ensure the structural strength of the mounting seat 41; or the mounting seat 41 and the mounting plate 21 may be detachably connected to facilitate the separate manufacturing of the mounting seat 41 and the mounting plate 21, thereby reducing the production difficulty of the mounting seat 41 and the mounting plate 21; thus, the connection between the mounting seat 41 and the mounting plate 21 ensures the stable connection between the snap assembly 4 and the mounting plate 21. The fixing member 5 is provided with a limiting hole 51, which is used to snap-fit ​​with one end of the snap 42 toward the top cover plate 3 to ensure the stability of the volute assembly 2 when connected to the top cover plate 3, thereby improving the stability of the volute assembly 2 when installed in the duct machine, and making it easy to disassemble the volute assembly 2 and the top cover plate 3. Moreover, compared with directly setting the limiting hole 51 on the top cover plate 3, by setting the fixing member 5, on the one hand, the setting of the limiting hole 51 will not damage the structural strength and sealing of the top cover plate 3; on the other hand, the distance between the limiting hole 51 and the volute 22 can be reduced, which is convenient for the spring buckle 42 to be inserted into the limiting hole 51. The end of the spring buckle 42 away from the top cover plate 3 is slidably connected to the mounting seat 41, so that the spring buckle 42 and the limiting hole 51 can be snapped or separated by sliding, which has the advantage of easy operation, that is, the convenience of assembly and disassembly between the volute assembly 2 and the top cover plate 3 is improved.

[0052] Optionally, combined Figure 1-Figure 10 As shown, the snap assembly 4 also includes an elastic member 43 and a button 44, and the button 44 is slidably connected to the mounting seat 41; the snap 42 includes an integrally formed sliding portion 422 and a connecting portion 421, and the connecting portion 421 is snap-fitted with the limiting hole 51, and the end of the sliding portion 422 away from the mounting plate 21 is connected to the button 44, and the end of the sliding portion 422 toward the mounting plate 21 is connected to the elastic member 43, and the end of the elastic member 43 away from the snap 42 is connected to the mounting seat 41 or the mounting plate 21; and the button 44 and the sliding portion 422 are both suitable for sliding in a direction toward the mounting plate 21 or away from the mounting plate 21.

[0053] The connecting portion 421 of the snap button 42 is engaged with the limiting hole 51, and the sliding portion 422 is slidably connected with the mounting seat 41; Figure 1 In the positive direction of the middle X-axis, the elastic member 43, the sliding part 422, and the button 44 are connected in sequence from the back to the front, the end of the button 44 away from the sliding part 422 is slidably connected to the mounting seat 41, the end of the elastic member 43 away from the sliding part 422 is connected to the mounting seat 41 or the mounting plate 21, and the button 44 and the sliding part 422 are both suitable for sliding in the direction toward the mounting plate 21 or away from the mounting plate 21; wherein the elastic member 43 is a spring, a spring sheet or other elastic device. When assembling the volute assembly 2 and the top cover plate 3, the installer first moves along the Figure 1The button 44 is pressed in the reverse direction of the middle X-axis to make the sliding part 422 move backward. At this time, the elastic member 43 is compressed, and the installer applies an upward force to the volute assembly 2, so that the connecting part 421 is inserted into the limiting hole 51 set on the top cover plate 3, and then the button 44 is released, and the elastic member 43 recovers its deformation, so that the connecting part 421 abuts against the hole wall of the limiting hole 51 to complete the assembly of the volute assembly 2 and the top cover plate 3; and the end of the connecting part 421 inserted into the limiting hole 51 is hook-shaped. After the connecting part 421 is engaged with the limiting hole 51, the end of the connecting part 421 inserted into the limiting hole 51 abuts against the side of the top cover plate 3 away from the volute 22 at the same time, and the top cover plate 3 limits the connecting part 421 (volute assembly 2) through the hole wall of the limiting hole 51 to prevent the volute assembly 2 from moving forward (i.e. Figure 6 X-axis positive), downward (i.e. Figure 6 Z-axis in the opposite direction) and left and right (i.e. Figure 1 The volute assembly 2 moves in the Y-axis direction, thereby improving the stability of the connection between the volute assembly 2 and the top cover plate 3.

[0054] Optionally, combined Figure 6-Figure 10 As shown, the mounting seat 41 includes an integrally formed mounting seat body 411 and a fixing plate 412, one end of the mounting seat body 411 is integrally formed with the mounting plate 21, and the fixing plate 412 is arranged at the other end of the mounting seat body 411; the end of the button 44 away from the sliding part 422 passes through the fixing plate 412 and extends out.

[0055] The fixing plate 412 is provided with a button 44 in the front-to-back direction (i.e. Fig. 9The first through hole 4121 moves in the direction of the X-axis (in the middle X-axis direction), and the end of the button 44 away from the connection with the sliding part 422 extends forward from the fixing plate 412 through the first through hole 4121. The hole wall of the first through hole 4121 guides the movement of the button 44 in the front-back direction, so as to facilitate the installation personnel to press the button 44, and after the installation personnel remove the pressing force on the button 44, the button 44 returns to the position before pressing under the action of the elastic member 43. For the convenience of description, the elastic member 43 is used as a spring as an example below. The end of the sliding part 422 of the snap 42 away from the fixing plate 412 is columnar, and a spring is sleeved on it. The end of the spring away from the sliding part 422 is connected to the mounting seat body 411 or the mounting plate 21. The connection between the mounting seat body 411 or the mounting plate 21 and the spring is provided with a second through hole 4111, and the second through hole 4111 is suitable for the end of the sliding part 422 away from the fixing plate 412 to pass through, so as to facilitate the snap 42 on the button 4 4 moves backward when pressed; wherein, with respect to the setting of the second through hole 4111, when the snap 42 moves backward, if the end of the sliding part 422 away from the fixing plate 412 first contacts the mounting seat body 411, the second through hole 4111 is set on the mounting seat body 411 or on the mounting seat body 411 and the mounting plate 21; if the end of the sliding part 422 away from the fixing plate 412 directly contacts the mounting plate 21 when the snap 42 moves backward, the second through hole 4111 is set on the mounting plate 21. In this way, the mounting seat 41 moves the snap 42 in the up and down directions (i.e., Fig. 9 The limit of the spring buckle 42 in the front-to-back direction (i.e. Fig. 9 and the mounting seat body 411 cooperates with the fixing plate 412 to enclose an area for accommodating the spring buckle 42 and the elastic member 43 to protect the spring buckle 42 and the elastic member 43, thereby ensuring the smooth assembly of the volute assembly 2 in the duct machine.

[0056] Furthermore, the mounting seat body 411 is preferably arranged perpendicular to the mounting plate 21 so that the rotating shaft of the wind wheel in the volute 22 is rotatably connected to the mounting seat body 411; in this way, the mounting seat body 411 supports the wind wheel in the volute 22, ensuring the stability of the wind wheel in the volute 22 during rotation, thereby ensuring the stable operation of the volute assembly 2 in the duct machine.

[0057] Optionally, combined Figure 6-Figure 10 As shown, the length of the end of the button 44 away from the sliding portion 422 extending out of the fixing plate 412 is greater than the sliding stroke of the snap 42 .

[0058] The sliding stroke L3 of the snap 42 is the maximum distance that the snap 42 can move in the reverse direction of the X-axis when the button 44 is not pressed. For example, when the second through hole 4111 penetrates the mounting seat body 411 and the mounting plate 21, the sliding stroke L3 of the snap 42 is the vertical distance from the end of the sliding portion 422 of the snap 42 away from the fixed plate 412 to the partition 1. The length L4 of the button 44 extending from the fixed plate 412 away from the end connected to the snap 42 is the vertical distance from the end of the button 44 away from the snap 42 to the fixed plate 412 when the button 44 is not pressed; preferably, L4>L3; when L4<L3, when the installer presses the button 44, the button 44 is easy to slip out of the first through hole 4121 in the reverse direction of the X-axis, resulting in an increase in the difficulty of assembling the volute assembly 2. Therefore, preferably, L4>L3 to ensure that the snap assembly 4 works stably.

[0059] Furthermore, preferably, L4-L3≥3mm, so as to ensure that when the installer presses the button 44, the button 44 will not sink into the first through hole 4121 along the reverse direction of the X-axis, thereby avoiding the situation where the installer cannot touch the button 44.

[0060] Furthermore, the maximum compression distance L1 of the elastic member 43 is preferably greater than the maximum movement stroke L2 of the button 44, wherein the maximum movement stroke L2 of the button 44 is the vertical distance from one end of the button 44 away from the fixed plate 412 to the side of the fixed plate 412 facing the mounting plate 21; in this way, when L1 is less than L2, the elastic member 43 is easily damaged by the maximum compression when the installer presses the button 44.

[0061] Optionally, combined Figure 3-Figure 5 As shown, the top cover plate 3 and the fixing member 5 are respectively provided with a positioning convex bump 311 and a positioning hole 52 , and the positioning convex bump 311 is plug-fitted with the positioning hole 52 .

[0062] In this embodiment, the positioning convex bump 311 can be arranged on the side of the top cover plate 3 facing the volute 22, and the positioning hole 52 can be arranged at a position on the fixing member 5 corresponding to the positioning convex bump 311; the positioning convex bump 311 can also be arranged on the side of the fixing member 5 facing the top cover plate 3, and the positioning hole 52 can be arranged on the top cover plate 3 corresponding to the positioning convex bump 311; the positioning convex bump 311 and the positioning hole 52 can also be arranged on both the top cover plate 3 and the fixing member 5, and the positioning convex bump 311 (positioning hole 52) on the top cover plate 3 is plugged in with the positioning hole 52 (positioning convex bump 311) on the fixing member 5; in this way, the fixing member 5 is pre-positioned on the top cover plate 3 by plugging in the positioning convex bump 311 and the positioning hole 52, so as to facilitate the setting of the fixing member 5 on the top cover plate 3, for example, after the fixing member 5 and the top cover plate 3 are plugged in with the positioning convex bump 311 and the positioning hole 52, the fixing member 5 and the top cover plate 3 are welded, riveted, bolted, etc.

[0063] Optionally, a boss 31 is provided on the top cover plate 3 , and one of a positioning convex bump 311 and a positioning hole 52 is provided on the boss 31 and the fixing member 5 respectively, and the boss 31 protrudes toward the volute 22 .

[0064] The boss is a ridge-shaped structure, a convex hull-shaped structure, a convex point-shaped structure or a rib-shaped structure, etc., and is used to strengthen the structural strength of the top cover plate 3. In this embodiment, the boss 31 is preferably protruding toward the volute 22, that is, the boss 31 is arranged on the side of the top cover plate 3 facing the volute 22; in this way, on the one hand, the structural strength of the top cover plate 3 is strengthened, the stability of the volute assembly 2 when connected to the top cover plate 3 is ensured, thereby ensuring the stability of the volute assembly 2 when installed in the air duct machine, and ensuring that there is no protrusion on the side of the top cover plate 3 away from the volute 22, so that the air duct machine can be tightly connected to the installation surface such as the ceiling through the top cover plate 3; on the other hand, the distance between the fixing member 5 arranged on the boss 31 and the mounting seat body 411 is reduced, which is convenient for the snap-fitting of the spring buckle 42 and the limiting hole 51, thereby facilitating the connection between the fixing member 5 and the top cover plate 3 at the boss 31.

[0065] Furthermore, in the present embodiment, the positioning bump 311 may be arranged on the side of the boss 31 facing the volute 22, and the positioning hole 52 may be arranged at a position on the fixing member 5 corresponding to the positioning bump 311; or the positioning bump 311 may be arranged on the side of the fixing member 5 facing the top cover plate 3, and the positioning hole 52 may be arranged at a position on the boss 31 corresponding to the positioning bump 311; or the positioning bump 311 and the positioning hole 52 may be arranged on both the boss 31 and the fixing member 5, and the positioning bump 311 (positioning hole 52) on the boss 31 may be plugged into and matched with the positioning hole 52 (positioning bump 311) on the fixing member 5.

[0066] Optionally, combined Figure 3-Figure 8 As shown, the boss 31 is a rib structure, and the rib structure is formed by the top cover plate 3 protruding toward the volute 22 .

[0067] In this embodiment, the boss 31 is preferably a rib structure, and the rib structure is formed by the top cover plate 3 protruding toward the volute 22 (for example, by stamping), so that the top cover plate 3 provided with the rib structure is a rib plate-like structure to improve the structural strength of the top cover plate 3. Moreover, compared with the boss 31 having a ridge-like structure, a convex hull-like structure or a convex dot-like structure, the reinforcing rib 23 having a rib structure can save the production cost of the top cover plate 3.

[0068] Optionally, combined Figure 3-Figure 8 As shown, the rib structure forms an avoidance groove 32 on the side of the top cover plate 3 facing the volute 22, and the limiting hole 51 is connected to the avoidance groove 32; when the spring buckle 42 is snap-fitted with the limiting hole 51, one end of the spring buckle 42 snap-fitted with the limiting hole 51 is located in the avoidance groove 32.

[0069] In this embodiment, the fixing member 5 is connected to the top cover plate 3 at the rib structure, and the rib structure is U-shaped, V-shaped or annular, etc., and forms an avoidance groove 32 connected to the limiting hole 51 on the side of the top cover plate 3 facing the volute 22, so as to avoid the top cover plate 3 interfering with the spring buckle 42 being inserted into the limiting hole 51, and makes one end of the spring buckle 42 that is engaged with the limiting hole 51 suitable for moving to a certain extent in the front-rear direction in the avoidance groove 32, so as to facilitate the assembly or disassembly of the spring buckle 42 and the limiting hole 51.

[0070] Optionally, combined Figure 2 , Fig.11 As shown, the volute assembly structure also includes a snap-on structure 6; the snap-on structure 6 is arranged on the mounting plate 21, and a slot structure 7 is provided at a position on the partition 1 corresponding to the snap-on structure 6, and / or the snap-on structure 6 is arranged on the partition 1, and a slot structure 7 is provided at a position on the mounting plate 21 corresponding to the snap-on structure 6; and the snap-on structure 6 is snap-fitted with the slot structure 7.

[0071] The mounting plate 21 and the partition 1 are detachably connected by the snap-fitting of the snap-fitting structure 6 and the slot structure 7. In this embodiment, the mounting plate 21 may be provided with a snap-fitting structure 6 and the partition 1 may be provided with a slot structure 7; or the mounting plate 21 may be provided with a slot structure 7 and the partition 1 may be provided with a snap-fitting structure 6; or the mounting plate 21 may be provided with a snap-fitting structure 6 and a slot structure 7, and the partition 1 may also be provided with a snap-fitting structure 6 and a slot structure 7; and the snap-fitting structure 6 (slot structure 7) on the mounting plate 21 and the corresponding slot structure 7 (slot structure 6) on the partition 1 are snap-fitted to ensure the stability of the volute assembly 2 when connected to the partition 1 and the convenience during disassembly and installation. Based on the snap-fitting of the spring buckle 42 and the limiting hole 51, the size of the slot structure 7 in the up-down direction is larger than the corresponding size of the snap-fitting structure 6, so that the snap-fitting structure 6 can be smoothly snapped into the slot structure 7, so that the snap-fitting structure 6 has a certain activity space in the slot structure 7, so that the spring buckle 42 can be smoothly snapped into the limiting hole 51 upward. For ease of description, the following is an example in which a snap-in structure 6 is provided on the mounting plate 21 and a slot structure 7 is provided on the partition 1. After the snap-in structure 6 is inserted into the slot structure 7, the partition 1 limits the snap-in structure 6 (volute assembly 2) through the slot wall of the slot structure 7 to prevent the volute assembly 2 from moving downward, left and right, and forward and backward. This ensures that after the snap-in structure 6 and the slot structure 7 are snapped together, the spring buckle 42 can be smoothly snapped into the limiting hole 51 upward, and based on the snap-in cooperation between the spring buckle 42 and the limiting hole 51, the snap-in cooperation between the slot structure 7 and the snap-in structure 6 further improves the stability of the volute assembly 2 when installed in the duct machine; moreover, compared with the use of fasteners to connect the volute assembly 2 with the partition 1 and the top cover plate 3, the snap-in cooperation between the slot structure 7 and the snap-in structure 6 and the snap-in cooperation between the spring buckle 42 and the limiting hole 51 greatly improve the convenience of disassembly and installation of the volute assembly 2 and the partition 1.
