[0049] It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0050] In combination with Figures 1-10 As shown in the drawings, the embodiments of the present disclosure provide an outer pipe 30 mounting assembly, which comprises a panel 10.

[0051] The outer pipe 30 mounting assembly is used for a fresh air machine.

[0052] The fresh air machine comprises an outer pipe 30, a fan, a heat exchange core, a sound insulation piece, etc.

[0053] The wall for mounting the fresh air machine is provided with a through hole, and the outer pipe 30 passes through the through hole. The outer pipe 30 defines a mounting space 301, and the fan, the heat exchange core, and the sound insulation piece are all located in the mounting space 301.

[0054] The fresh air machine further comprises a rainproof cap and a cover shell. The rainproof cap is arranged at one end of the outer pipe 30 extending out of the wall, the panel 10 is arranged indoors, and the outer pipe 30 is connected between the rainproof cap and the panel 10. The rainproof cap is provided with a first air inlet and outlet, and the cover shell is arranged at one end of the panel 10 away from the outer pipe 30. The cover shell defines a second air inlet and outlet, and the first air inlet and outlet and the second air inlet and outlet are both in communication with the mounting space 301. Under the driving of the fan, air enters the mounting space 301 through one of the first air inlet and outlet and the second air inlet and outlet, and flows out from the other one, and exchanges heat with the heat exchange core in the mounting space 301.

[0055] The panel 10 is provided with a first mounting structure 102 for mounting the outer pipe 30, and is provided with a mounting portion for mounting the adjusting member 20, wherein the adjusting member 20 is provided with a second mounting structure 202 for mounting the outer pipe 30, and the size of the outer pipe 30 matched with the first mounting structure 102 is different from the size of the outer pipe 30 matched with the second mounting structure 202.

[0056] As shown in Figures 7 to 10 , when the size of the outer pipe 30 is matched with the first mounting structure 102, the outer pipe 30 is matched with the first mounting structure 102 to realize the assembly of the outer pipe 30; as shown in Figures 1 to 4 , when the size of the outer pipe 30 cannot be matched with the first mounting structure 102, the adjusting member 20 is mounted on the panel 10, the outer pipe 30 is matched with the second mounting structure 202 on the adjusting member 20, and the assembly of the outer pipe 30 on the panel 10 is realized through the adjusting member 20.

[0057] In this way, for the outer pipe 30 of different sizes, the outer pipe 30 can be matched with the first mounting structure 102 or the second mounting structure 202, so that the panel 10 does not need to be replaced, and the replacement cost of the outer pipe 30 is reduced.

[0058] Optionally, the mounting portion includes a first through hole 101 penetrating the panel 10, and in the state that the outer pipe 30 is mounted on the first mounting structure 102, the outer pipe 30 is communicated with the first through hole 101.

[0059] On the one hand, as shown in Figure 10 , in the state that the outer pipe 30 is mounted on the first mounting structure 102, the outer pipe 30 is communicated with the first through hole 101, the first through hole 101 is communicated with the second air inlet and outlet, the communication between the mounting space 301 and the second air inlet and outlet is realized, and the air inlet or air outlet of the second air inlet and outlet is realized. On the other hand, the installation of the adjusting member 20 is realized through the first through hole 101, the function of the first through hole 101 is increased, no additional structure needs to be arranged on the panel 10 due to the arrangement of the adjusting member 20, the compactness of the structure of the panel 10 is improved, and the cost of the fresh air machine is reduced.

[0060] Optionally, as shown in Figures 1 to 6 , the adjusting member 20 is provided with a second through hole 201, and in the state that the outer pipe 30 is mounted on the second mounting structure 202, the outer pipe 30 is communicated with the second through hole 201.

[0061] In the state that the outer pipe 30 is mounted on the second mounting structure 202, the outer pipe 30 is communicated with the second through hole 201, the second through hole 201 is communicated with the second air inlet and outlet, the communication between the mounting space 301 and the second air inlet and outlet is realized, and the air inlet or air outlet of the second air inlet and outlet is realized. In turn, the normal air inlet and outlet function of the fresh air machine is realized.

[0062] The adjusting member 20 is annular, and when the adjusting member 20 is assembled to the panel 10, the adjusting member 20 covers the part of the first through hole 101 except the second through hole 201 to prevent air leakage from the part of the first through hole 101 except the second through hole 201.

[0063] As shown in Figure 6 , the first through hole 101 is a circular hole, the adjusting member 20 is a circular ring, and the second through hole 201 is a circular hole.

[0064] Optionally, the first mounting structure 102 is located outside the second mounting structure 202, and the size of the outer pipe 30 matched with the first mounting structure 102 is larger than the size of the outer pipe 30 matched with the second mounting structure 202.

[0065] The first mounting structure 102 is located outside the second mounting structure 202, wherein the direction away from the axis of the outer pipe 30 is outside, and the direction close to the axis of the outer pipe 30 is inside. Thus, the size of the outer pipe 30 matched with the first mounting structure 102 is larger than the size of the outer pipe 30 matched with the second mounting structure 202.

[0066] In other words, as shown in Figures 7 to 10 , when the fresh air machine needs to use a large-size outer pipe 30, the large-size outer pipe 30 is matched with the first mounting structure 102, and the adjusting member 20 does not need to be installed on the panel 10. As shown in Figures 1 to 6 , when the fresh air machine needs to use a small-size outer pipe 30, the adjusting member 20 is needed at this time, and specifically, the adjusting member 20 is installed on the panel 10, and the small-size outer pipe 30 is matched with the second mounting structure 202 to realize the installation of the small-size outer pipe 30 on the panel 10. Thus, the assembly of outer pipes 30 of different sizes on the panel 10 is realized.

[0067] Taking the outer pipe 30 as a cylindrical pipe as an example, the large-size outer pipe 30 refers to the outer diameter or inner diameter of the outer pipe 30 being larger, and the small-size outer pipe 30 refers to the outer diameter or inner diameter of the outer pipe 30 being smaller.

[0068] The first mounting structure 102 is fixedly connected with the outer pipe 30, and the fixed connection is detachable or non-detachable. The first mounting structure 102 can be various forms, as long as it can fix the outer pipe 30.

[0069] For example, as shown in Figure 5 and Figure 10As shown, the first mounting structure 102 includes a first rib 103 disposed on the side of the panel 10 facing the outer tube 30. The first rib 103 is disposed outside the first through hole 101 and surrounds the first through hole 101. The first rib 103 and the panel 10 together form a first mounting position 104. The first rib 103 can be a single annular rib, annularly fitted outside the first through hole 101. There can also be more than one first rib 103, with multiple first ribs 103 arranged sequentially along the circumference of the first through hole 101. The outer tube 30 is disposed within the first mounting position 104 and abuts against the first rib 103. The first rib 103 secures the outer tube 30.

[0070] For example, the first mounting structure 102 includes a first magnetic structure, and the outer tube 30 is provided with a second magnetic structure. The first magnetic structure and the second magnetic structure are magnetically attracted together.

[0071] The second mounting structure 202 is fixedly connected to the outer tube 30, and can be either detachable or non-detachable. The second mounting structure 202 can be of various forms, as long as it can fix the outer tube 30.

[0072] For example, such as Figure 6 As shown, the second mounting structure 202 includes a second rib 203 disposed on the side of the panel 10 facing the outer tube 30. The second rib 203 is disposed outside the second through hole 201 and surrounds the second through hole 201. The second rib 203 and the panel 10 together form the second mounting position 204. The second rib 203 can be a single annular rib, annularly sleeved on the outside of the second through hole 201. There can also be more than one second rib 203, with multiple second ribs 203 arranged sequentially along the circumference of the second through hole 201. The outer tube 30 is disposed within the second mounting position 204 and abuts against the second rib 203. The second rib 203 secures the outer tube 30.

[0073] For example, the second mounting structure 202 includes a third magnetic structure, and the outer tube 30 is provided with a fourth magnetic structure. The third magnetic structure and the fourth magnetic structure are magnetically attracted together.

[0074] Optionally, the adjusting member 20 is provided with a mounting mating part, which mates with the adjusting member 20 to assemble the adjusting member 20 onto the panel 10, and the mounting part and the mounting mating part are detachably connected.

[0075] The adjustment component 20 is assembled on the panel 10 through the cooperation of the mounting part and the mounting mating part. The mounting part and the mounting mating part are detachably connected, which makes it easy to assemble the adjustment component 20 onto the panel 10 and easy to remove it from the panel 10 without damaging the structure of the panel 10.

[0076] Optionally, such as Figure 5As shown, one of the mounting portion and the mounting mating portion comprises the first clasp 206, and the other comprises the first clamping groove 106, and the first clasp 206 is inserted into the first clamping groove 106.

[0077] The first clasp 206 is inserted into the first clamping groove 106 to realize the assembly of the adjusting piece 20 on the panel 10; when the first clasp 206 is separated from the first clamping groove 106, the adjusting piece 20 is separated from the panel 10.

[0078] Optionally, a movement gap 107 is arranged between the first clasp 206 and the first clamping groove 106, so that the first clasp 206 can move relative to the first clamping groove 106; the mounting portion further comprises a sub-connection portion, and the mounting mating portion further comprises a sub-connection mating portion 210, and when the first clasp 206 moves relative to the first clamping groove 106, the sub-connection portion can be matched or separated from the sub-connection mating portion 210.

[0079] When the adjusting piece 20 is mounted on the panel 10, the first clasp 206 is inserted into the first clamping groove 106, and then the first clasp 206 is moved relative to the first clamping groove 106, so that the sub-connection portion moves relative to the sub-connection mating portion 210, and the sub-connection portion is matched with the sub-connection mating portion 210.

[0080] When the adjusting piece 20 is removed from the panel 10, the first clasp 206 is moved relative to the first clamping groove 106, so that the sub-connection portion moves relative to the sub-connection mating portion 210, and the sub-connection portion is separated from the sub-connection mating portion 210.

[0081] In this way, through the cooperation of the first clasp 206 and the first clamping groove 106, and the cooperation of the sub-connection portion and the sub-connection mating portion 210, the assembly of the adjusting piece 20 on the panel 10 is realized.

[0082] The sub-connection mating portion 210 and the first clasp 206 or the first clamping groove 106 arranged on the adjusting piece 20 are arranged along the circumference of the adjusting piece 20.

[0083] The number of the sub-connection mating portion 210 is one or more. When there are multiple, the multiple sub-connection mating portions 210 are arranged along the circumference of the adjusting piece 20. For example, Figure 6 As shown, the first clasp 206 is arranged on the adjusting piece 20, the number of the sub-connection mating portion 210 is three, the three sub-connection mating portions 210 and the first clasp 206 are arranged on the extension of the adjusting piece 20, and are arranged along the circumference of the adjusting piece 20, so that the adjusting piece 20 can be stably fixed to the panel 10.

[0084] Optionally, as shown in FIG. 2, Figure 11As shown, the panel 10 and the adjusting member 20 are in an integral structure, so as to simplify the manufacturing process of the panel 10 and the adjusting member 20, reduce the manufacturing cost, and improve the installation efficiency of the fresh air machine when the adjusting member 20 is needed to be used.

[0085] Optionally, a gap 40 is arranged at the connection between the panel 10 and the adjusting member 20.

[0086] The gap 40 can reduce the connection area between the panel 10 and the adjusting member 20, so as to facilitate the disassembly of the adjusting member 20 from the panel 10 when the adjusting member 20 is not needed to be used.

[0087] The gap 40 is arranged at the connection between the outer periphery of the adjusting member 20 and the panel 10. The number of the gap 40 can be one or multiple, and when the number is multiple, the multiple gaps 40 are arranged along the circumference of the adjusting member 20.

[0088] As shown, Figure 6 The adjusting member 20 includes an adjusting body 208, and the second mounting structure 202 is arranged on the adjusting body 208.

[0089] The first buckle 206 is arranged on one side of the adjusting body 208, and the first clamping groove 106 is arranged on the side of the panel 10 away from the outer tube 30. When the first buckle 206 is located in the first clamping groove 106, the first buckle 206 is provided with a relief gap towards the surface of the panel 10 and / or the first clamping groove 106 is provided with a relief gap towards the surface of the first clamping groove 106, and the relief gap forms a movement gap 107, so that the first buckle 206 can rotate relative to the first clamping groove 106 along the movement gap 107. When the first buckle 206 rotates relative to the first clamping groove 106 along the movement gap 107, the sub-connection part cooperates with or separates from the sub-connection matching part 210.

[0090] One of the sub-connection part and the sub-connection matching part 210 includes the second buckle 207, and the other includes the second clamping groove 108, and the second buckle 207 is matched with the second clamping groove 108 to realize the clamping connection between the second buckle 207 and the second clamping groove 108.

[0091] Alternatively, one of the sub-connection part and the sub-connection matching part 210 includes the first screw hole, and the other includes the second screw hole, and the screw passes through the first screw hole and the second screw hole to realize the screw connection between the sub-connection part and the sub-connection matching part 210.

[0092] The first buckle 206, the second buckle 207, the first clamping groove 106 and the second clamping groove 108 can be provided with a guide slope to facilitate the insertion or extraction of the first buckle 206 into or out of the first clamping groove 106 and the insertion or extraction of the second buckle 207 into or out of the second clamping groove 108.

[0093] The second mounting structure 202 is arranged on the adjusting body 208.

[0094] The second mounting structure 202 is arranged on the adjusting body 208 close to the second through hole 201, and the number of the second mounting structure 202 can be one or multiple, and the multiple second mounting structures 202 are sequentially arranged along the radial direction of the second through hole 201.

[0095] In this way, for the outer pipe 30 of multiple different sizes, the second mounting structure 202 in different positions can be matched, so that the adjusting piece 20 can be adapted to the outer pipe 30 of multiple different sizes, and the application range of the adjusting piece 20 is further improved.

[0096] Optionally, as shown in Figure 5 and Figure 6 The adjusting piece 20 further comprises an abutting portion 209, the mounting and matching portion and the abutting portion 209 are arranged on the opposite sides of the adjusting body 208, and the abutting portion 209 abuts against the panel 10.

[0097] The abutting portion 209 is arranged on the side of the adjusting body 208 facing the outer pipe 30, and the mounting and matching portion is arranged on the side of the adjusting body 208 away from the outer pipe 30. When the adjusting piece 20 is installed on the panel 10, the mounting and matching portion is matched with the side of the panel 10 away from the outer pipe 30, and the abutting portion 209 abuts against the side of the panel 10 facing the outer pipe 30, so that the mounting and matching portion can limit the movement of the adjusting piece 20 in the direction close to the outer pipe 30, and the abutting portion 209 can limit the movement of the adjusting piece 20 in the direction away from the outer pipe 30.
