[0002] Portable air conditioners, such as portable air conditioners, are gaining popularity among users because they do not require professional installation and can be easily moved. Mobile air conditioners are generally connected to windows via air ducts to achieve heat exchange with the outdoor environment. In related technologies, some mobile air conditioners use a dual-duct structure, where the air intake and exhaust between the mobile air conditioner and the outdoor environment are respectively achieved through the air intake duct and the exhaust duct. To improve the convenience of user installation, the dual-duct structure is generally designed to place the exhaust duct inside the air intake duct, making the two ducts integrated. When installing, the user only needs to buckle it onto the sealing plate as a single duct and install it in the window through the sealing plate. However, due to the high overall hardness of the dual-duct structure, once the dual-duct structure is fixed in the window, the mobile air conditioner is difficult to move, which greatly limits the user.

[0046] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0047] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0048] In the description of this utility model, "a plurality" means more than two. The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0049] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0050] A portable air conditioner is a device that can be easily moved around. Its housing integrates components such as the compressor, evaporator, condenser, supply fan, and exhaust fan. The base of a portable air conditioner is typically equipped with casters, allowing for easy movement to suit different usage scenarios. Because portable air conditioners don't require professional installation, they can significantly reduce installation costs and are gaining popularity among users.

[0051] Portable air conditioners are typically connected to windows via air ducts to exchange heat with the outdoor environment. Traditional portable air conditioners typically use a single air duct, one end of which is connected to the exhaust port of the housing and the other end is fixed to the window via a sealing plate. The exhaust fan then exhausts the heat-exchanged air through the duct to the outdoor environment.

[0052] To improve the energy efficiency of mobile air conditioners, related art uses a dual-duct structure. This structure consists of an inlet duct and an exhaust duct. The inlet duct draws in air from the outdoor environment. After heat exchange, the exhaust fan exhausts the air to the outdoor environment through the exhaust duct. However, to improve user installation convenience, the dual-duct structure is generally designed to place the exhaust duct inside the inlet duct, forming the two ducts into one. During installation, users only need to buckle the sealing plate like a single duct. Due to the high overall rigidity of the dual-duct structure, once the dual-duct structure is fixed in the window, the mobile air conditioner is difficult to move, which greatly limits the user.

[0053] Reference Figure 1 and Figure 3 As shown, in order to solve the problem of difficulty in moving an air conditioner such as a mobile air conditioner after the exhaust duct 300 and the air inlet duct 400 are fixed, the present invention provides an air inlet and exhaust assembly 1000 mounted on the housing 2000 of the air conditioner. To facilitate the description of the embodiments of the present invention, the following description will take a mobile air conditioner as an example. The air inlet and exhaust assembly 1000 of the present embodiment includes a connector 100, a sealing plate 200, an exhaust duct 300, and an air inlet duct 400. One end of the exhaust duct 300 and the air inlet duct 400 is mounted on the connector 100, which is mounted on the sealing plate 200 and is then mounted to the window 3000 through the sealing plate 200; the other ends of the exhaust duct 300 and the air inlet duct 400 are mounted on the housing 2000.

[0054] Reference Figure 3 、 Figure 5 and Figure 6 As shown, the connector 100 includes a first mounting seat 110 and a second mounting seat 120 arranged along a first direction. Figure 5 The left and right directions shown are also the length directions of the sealing plate 200 (eg Figure 7 As shown). The first mounting base 110 is provided with a first through hole 111, and the second mounting base 120 is provided with a second through hole 121. The first through hole 111 and the second through hole 121 are respectively connected to the outdoor environment. Figure 1 and Figure 7 As shown, the sealing plate 200 is connected to the connector 100, and the connector 100 and the sealing plate 200 are connected by a snap-fit ​​connection to achieve detachability; alternatively, the connector 100 and the sealing plate 200 can also be connected by screws or manufactured by integral molding.

[0055] Reference Figure 1 and Figure 2 As shown, it should be noted that the opening direction of the window 3000 generally includes left and right opening (such as Figure 1 as shown) or open in up and down directions (as shown Figure 2 As shown). Therefore, depending on the actual installation environment, the sealing plate 200 may need to be installed on the left, right, bottom or top side of the window 3000. In order to achieve the sealing performance of the sealing plate 200 on the window, the sealing plate 200 is configured to be installed on one side of the window along the opening direction of the window 3000. The opening direction of the window 3000 is the second direction, which is perpendicular to the first direction. For example, referring to Figure 1 As shown, if the window 3000 is opened from bottom to top, that is, the second direction is the up-down direction, then the sealing plate 200 is horizontally placed and installed on the lower side of the window, that is, the first direction is the left-right direction; Figure 2 As shown, if the window 3000 is opened from left to right, that is, the second direction is the left-right direction, then the sealing plate 200 is vertically placed and installed on the left side of the window, that is, the first direction is the up-down direction.

[0056] Reference Figure 4 、 Figure 5 and Figure 6 As shown, the exhaust duct 300 is connected to the first mounting base 110 and the exhaust port 2100 of the housing 2000, and is used to connect the first through hole 111 and the exhaust port 2100. The exhaust duct 300 includes a first telescopic tube 310 and a first end cap 320. The first telescopic tube 310 is a telescopic air duct made of materials such as rubber or polyurethane. Steel wire can also be added to the above structure to increase the strength of the air duct. The first end cap 320 is fixedly connected to the end of the first telescopic tube 310 close to the connector 100. The first end cap 320 and the first telescopic tube 310 are integrally formed. Alternatively, the first end cap 320 and the first telescopic tube 310 can also be connected by heat sealing welding or other methods. The first end cap 320 is arranged in the first mounting base 110 and is adapted to the first mounting base 110, so that the first end cap 320 is not easily detached from the connector 100. The first end cover 320 can rotate relative to the first mounting seat 110 , and the end of the exhaust pipe 300 connected to the joint 100 can rotate within the first mounting seat 110 .

[0057] Reference Figure 4 、 Figure 5 and Figure 6As shown, the air inlet duct 400 is connected to the first mounting base 110 and the air inlet 2200 of the housing 2000, and is used to connect the second through hole 121 and the air inlet 2200. The air inlet duct 400 includes a second telescopic tube 410 and a second end cap 420 located at one end of the second telescopic tube 410. The second telescopic tube 410 is a telescopic air duct made of materials such as rubber or polyurethane. Steel wire can also be added to the above structure to increase the strength of the air duct. The second end cap 420 is fixedly connected to the end of the second telescopic tube 410 near the connector 100. The second end cap 420 and the second telescopic tube 410 can also be integrally formed. Alternatively, the second end cap 420 and the second telescopic tube 410 can also be connected by heat sealing welding or other methods. The second end cap 420 is disposed within the second mounting base 120 and is compatible with the second mounting base 120, making it difficult for the second end cap 420 to fall out of the connector 100. The second end cover 420 can rotate relative to the second mounting base 120 , and the end of the air inlet pipe 400 connected to the joint 100 can rotate within the second mounting base 120 .

[0058] Reference Figure 6 and Figure 8 As shown, the first mounting base 110 and the second mounting base 120 of the present embodiment are configured to be spaced apart or partially connected along a first direction. The first end cap 320 and the second end cap 420 are spaced apart along the first direction, so that the first end cap 320 and the second end cap 420 do not interfere with each other during rotation. However, the first telescopic tube 310 and the second telescopic tube 410 can be spaced apart from each other, or at least partially abutted, as long as the first telescopic tube 310 and the second telescopic tube 410 can easily move relative to each other and rotate independently.

[0059] The air intake and exhaust assembly 1000 of the present invention increases the flexibility of each air duct by arranging the air intake duct 400 and the exhaust duct 300 in parallel, allowing for easy relative movement and independent twisting. Furthermore, after the air intake duct 400 and the exhaust duct 300 are fixedly connected to the housing 2000 and the sealing plate 200 via the joint 100, the air intake duct 400 and the exhaust duct 300 are configured to be able to rotate relative to the joint 100, respectively. This allows the portable air conditioner to be easily moved to adjust its placement, and the sealing plate 200 can also be easily rotated to adapt to installation on a window 3000 that opens left and right or on a window 3000 that opens up and down. Alternatively, one of the air intake duct 400 and the exhaust duct 300 can rotate relative to the joint 100, while the other cannot.

[0060] It is understandable that the air intake and exhaust assembly 1000 of another embodiment of the present invention may not include the sealing plate 200 .

[0061] Reference Figure 7 and Figure 8 As shown, the outer wall of the connector 100 of this embodiment of the utility model is provided with multiple mounting clips 130, which are arranged at intervals. The sealing plate 200 is provided with a third through hole 210 for accommodating the connector 100. The inner wall of the third through hole 210 is provided with multiple locking holes 220. The number of locking holes 220 is the same as the number of mounting clips 130, and the multiple locking holes 220 and the multiple mounting clips 130 are matched one-to-one. The connector 100 and the sealing plate 200 of this embodiment are detachably connected, which facilitates the installation and storage of the air intake and exhaust assembly 1000.

[0062] Reference Figure 8 As shown, the connector 100 of the present embodiment further includes an isolation plate 140, which is disposed between the first through hole 111 and the second through hole 121 and is used to isolate the first through hole 111 from the second through hole 121. The isolation plate 140 can prevent the exhaust airflow from the connector 100 from directly entering the air inlet duct 400, thereby improving the energy efficiency of the mobile air conditioner.

[0063] Reference Figure 6 As shown, in an embodiment of the present invention, the first mounting seat 110 includes a first bottom wall 112, a first circumferential wall 113 and a first anti-slip member 114. The first bottom wall 112 cooperates with the outer side of the first end cover 320, and the first bottom wall 112 is used to limit the first end cover 320 from slipping out axially outward from the joint 100, and the first through hole 111 is provided on the first bottom wall 112. The first circumferential wall 113 is connected to the first bottom wall 112, and the first circumferential wall 113 is provided around at least part of the circumference of the first through hole 111, that is, the first circumferential wall 113 can be a ring-shaped structure, or can be an arc-shaped structure with multiple intervals. The first circumferential wall 113 is used to limit the first end cover 320 from slipping out circumferentially, and the first circumferential wall 113 also has a certain guiding function, and can play a guiding role during the rotation of the first end cover 320. It is understood that the first circumferential wall 113 is compatible with the circumferential wall of the first end cap 320, and a certain gap exists between the first circumferential wall 113 and the circumferential wall of the first end cap 320 to ensure that the first end cap 320 can rotate within the first mounting seat 110. The first retaining member 114 is connected to the first bottom wall 112, or to the first circumferential wall 113. The first retaining member 114 is used to limit the first end cap 320 from dislodging axially inward from the connector 100. For example, the first retaining member 114 can be a buckle, a stopper, a rib, or other structure. It is understood that the axial distance between the first bottom wall 112 and the first retaining member 114 is compatible with the axial length of the first end cap 320, so that a certain gap exists between the first bottom wall 112 and the first retaining member 114 to ensure that the first end cap 320 can rotate within the first mounting seat 110.

[0064] The first bottom wall 112, the first peripheral wall 113 and the first anti-slip member 114 together form a first space, and the first end cover 320 is located in the first space. The first end cover 320 is adapted to the first space, thereby ensuring that the first end cover 320 can rotate in the first space, and the first anti-slip member 114 and the first bottom wall 112 and the first peripheral wall 113 together limit the first end cover 320 from being separated from the first mounting seat 110, thereby ensuring a stable connection between the first end cover 320 and the first mounting seat 110.

[0065] Reference Figure 6 As shown, in one embodiment of the present invention, the first retaining member 114 is a first buckle 150. The first buckle 150 includes a first arm portion 151 and a first buckle portion 152. The first arm portion 151 is connected to the first bottom wall 112, and the first buckle portion 152 is connected to the end of the first arm portion 151 away from the first bottom wall 112 and protrudes inwardly from the first arm portion 151. The first buckle portion 152 is used to limit the end of the first end cap 320 away from the first bottom wall 112. A plurality of first buckles 150 can be provided, and the plurality of first buckles 150 are spaced apart along the circumference of the first through hole 111. When the first end cap 320 is installed in the first mounting seat 110, the first arm portion 151 of the first buckle 150 undergoes elastic deformation, allowing the first end cap 320 to be installed in the first space, while the first buckle portion 152 limits the first end cap 320 to prevent it from falling out of the first mounting seat 110. The first retaining member 114 of this embodiment utilizes a first buckle 150 to facilitate easy installation and removal of the exhaust duct 300. To enhance the elasticity of the first buckle 150 and maintain the compactness of the first mounting base 110, the first peripheral wall 113 includes multiple arcuate structures with first notches 115 defined between the multiple arcuate structures. The first buckle 150 is positioned within the first notches 115.

[0066] Alternatively, the first arm portion 151 may also be located outside the annular structure or outside the multi-segment arc structure, which is not specifically limited here.

[0067] Reference Figure 6 As shown, in the embodiment of the present invention, a reinforcing rib 116 is provided at the connection between the first buckle 150 and the first bottom wall 112 to improve the connection strength of the first buckle 150 and thereby improve the durability of the first buckle 150. The reinforcing rib 116 is provided on the outer side of the first arm portion 151, that is, on the side that protrudes away from the first buckle portion 152.

[0068] In another embodiment of the present invention, the first retaining member 114 includes a plurality of first clips 150. The plurality of first clips 150 are arranged around the circumference of the first through hole 111, and the first arm portions 151 of the plurality of first clips 150 are configured as the first peripheral wall 113. That is, the plurality of first clips 150 are configured to function as both the first peripheral wall 113 and the first retaining member 114, which can simplify the structure of the first mounting base 110 while also ensuring the limiting requirements for the first end cover 320.

[0069] In another embodiment of the present invention, the first retaining member 114 is a first baffle, which is a post-installed component. That is, after the first end cover 320 is installed in the first mounting seat 110, the first baffle is fixedly connected to the first bottom wall 112 or the first peripheral wall 113, thereby meeting the axial inner limit requirement of the first end cover 320. It is understood that the post-installed first baffle can be fixed by screw connection or bonding, etc., which is not specifically limited here.

[0070] In another embodiment of the present invention, the first retaining member 114 is a first edge, which is disposed around at least a portion of the circumference of the first peripheral wall 113 and is integrally formed with the first peripheral wall 113. The first edge and the first peripheral wall 113 are formed into an elastic structure. Under the action of an external force, the first edge elastically deforms, causing the inner hole of the first edge to expand, allowing the first end cap 320 to be installed into the first space of the first mounting seat 110 through the expanded inner hole. During normal use, because the first edge does not deform, the first end cap 320 cannot escape from the inner hole of the first edge, thereby satisfying the requirement that the first edge limit the axial inner side of the first end cap 320.

[0071] Reference Figure 6 As shown, the second mounting base 120 can adopt the same structure as the first mounting base 110, or can adopt a different structure, or can adopt different embodiments described above, which is not specifically limited here. For the convenience of manufacturing, the second mounting base 120 and the first mounting base 110 generally adopt the same structure, so the specific structure of the second mounting base 120 can be understood by referring to the above embodiment of the first mounting base 110.

[0072] Reference Figure 6As shown, the second mounting seat 120 of the embodiment of the present invention includes a second bottom wall 122, a second peripheral wall 123 and a second anti-slip member 124. The second bottom wall 122 cooperates with the outer side of the second end cover 420, and the second bottom wall 122 is used to limit the second end cover 420 from slipping out axially outward from the joint 100, and the second through hole 121 is provided on the second bottom wall 122. The second peripheral wall 123 is connected to the second bottom wall 122, and the second peripheral wall 123 is arranged around at least part of the circumference of the second through hole 121, that is, the second peripheral wall 123 can be a ring-shaped structure, or it can be an arc-shaped structure with multiple intervals. The second peripheral wall 123 is used to limit the second end cover 420 from slipping out in the circumferential direction, and the second peripheral wall 123 also has a certain guiding function, which can play a guiding role during the rotation of the second end cover 420. It is understood that the second circumferential wall 123 is compatible with the circumferential wall of the second end cap 420, and a certain gap exists between the second circumferential wall 123 and the circumferential wall of the second end cap 420 to ensure that the second end cap 420 can rotate within the second mounting seat 120. The second retaining member 124 is connected to the second bottom wall 122, or to the second circumferential wall 123. The second retaining member 124 is used to limit the second end cap 420 from escaping axially inward from the connector 100. For example, the second retaining member 124 can be a buckle, a blocking plate, a rib, or other structure. It is understood that the axial distance between the second bottom wall 122 and the second retaining member 124 is compatible with the axial length of the second end cap 420, so that a certain gap exists between the second bottom wall 122 and the second retaining member 124 to ensure that the second end cap 420 can rotate within the second mounting seat 120.

[0073] The second bottom wall 122, the second peripheral wall 123 and the second anti-slip member 124 together form a second space, and the second end cover 420 is located in the second space. The second end cover 420 is adapted to the second space, thereby ensuring that the second end cover 420 can rotate in the second space, and the second anti-slip member 124 and the second bottom wall 122 and the second peripheral wall 123 together limit the second end cover 420 from being separated from the second mounting seat 120, thereby ensuring a stable connection between the second end cover 420 and the second mounting seat 120.

[0074] In one embodiment of the present invention, the second retaining member 124 is a second clip 160. The second clip 160 includes a second arm 161 and a second clip 162. The second arm 161 is connected to the second bottom wall 122. The second clip 162 is connected to the end of the second arm 161 away from the second bottom wall 122 and protrudes toward the inside of the second arm 161. The second clip 162 is used to limit the end of the second end cover 420 away from the second bottom wall 122. A plurality of second clips 160 can be provided, and the plurality of second clips 160 are arranged at intervals along the circumference of the second through hole 121. When the second end cover 420 is installed in the second mounting seat 120, the second arm 161 of the second clip 160 undergoes elastic deformation, so that the second end cover 420 is installed in the second space, and the second clip 162 limits the second end cover 420 to prevent the second end cover 420 from falling out of the second mounting seat 120. The second retaining member 124 of this embodiment utilizes a second clip 160 to facilitate easy installation and removal of the air inlet duct 400. To enhance the elasticity of the second clip 160 and maintain the compactness of the second mounting base 120, the second peripheral wall 123 includes multiple arcuate structures with second notches 125 defined between the multiple arcuate structures. The second clip 160 is positioned within the second notches 125.

[0075] In another embodiment of the present invention, the second retaining member 124 is a second baffle, which is a post-installed component. That is, after the second end cover 420 is installed in the second mounting seat 120, the second baffle is fixedly connected to the second bottom wall 122 or the second peripheral wall 123, thereby meeting the axial inner limit requirement of the second end cover 420. It is understood that the post-installed second baffle can be fixed by screw connection or bonding, etc., which is not specifically limited here.

[0076] In another embodiment of the present invention, the second retaining member 124 is a second peripheral edge, which is disposed around at least a portion of the circumference of the second peripheral wall 123 and is integrally formed with the second peripheral wall 123. The second peripheral edge and the second peripheral wall 123 are formed into an elastic structure. Under the action of an external force, the second peripheral edge elastically deforms, causing the inner hole of the second peripheral edge to expand, allowing the second end cap 420 to be installed into the second space of the second mounting seat 120 through the expanded inner hole. During normal use, because the second peripheral edge does not deform, the second end cap 420 cannot escape from the inner hole of the second peripheral edge, thereby satisfying the requirement that the second peripheral edge limit the axial inner side of the second end cap 420.

[0077] Alternatively, the second arm portion 161 may also be located outside the annular structure or outside the multi-segment arc structure, which is not specifically limited here.

[0078] Reference Figure 5 and Figure 6As shown, the first telescopic tube 310 and the second telescopic tube 410 are configured to be spaced apart from each other, that is, the first telescopic tube 310 and the second telescopic tube 410 are spaced apart along their extension direction. Therefore, the first telescopic tube 310 and the second telescopic tube 410 can be manufactured and installed separately, which helps simplify the manufacturing process and improve assembly efficiency. Moreover, the air inlet duct 400 and the exhaust duct 300 can operate more smoothly and twist more easily when they rotate independently. Therefore, when the user moves the mobile air conditioner, the air inlet duct 400 and the exhaust duct 300 can easily rotate and twist, making it easy to move the mobile air conditioner and adjust its placement. In addition, the user can easily rotate the air inlet and exhaust assembly 1000, so that the mobile air conditioner can be installed on windows 3000 with different opening directions.

[0079] Reference Figure 9 、 Figure 10 and Figure 11 As shown, another embodiment of the present invention, an air intake and exhaust assembly 1000, is substantially identical to the air intake and exhaust assembly 1000 of the aforementioned embodiment, differing in that this embodiment further includes an outer cover 500, which wraps around the first and second telescopic tubes 310, 410. The outer cover 500 provides dust protection, and when wrapped around the first and second telescopic tubes 310, 410, they form a unified whole, enhancing their aesthetic appeal. The outer cover 500 is made of a soft material that can expand and contract with the first and second telescopic tubes 310, 410, such as pleated cloth, nylon, or core-spun yarn.

[0080] Reference Figure 11 、 Figure 12 and Figure 13 As shown, to enhance the installation stability of the outer cover 500, a first connecting portion 510 is provided at one end of the outer cover 500 near the connector 100 in this embodiment of the present invention. The first connecting portion 510 is used to securely connect the outer cover 500 to the connector 100. The first mounting base 110 includes a first peripheral wall 113, and the second mounting base 120 includes a second peripheral wall 123. The first connecting portion 510 is disposed around the periphery of the outer cover 500, wrapping around the outside of the first and second peripheral walls 113, 123. The first connecting portion 510 can be secured to the first and second peripheral walls 113, 123 by narrowing the opening of the first connecting portion 510. For example, the first connecting portion 510 may be a structure such as Velcro, a tightening cord, or a rubber band.

[0081] Reference Figure 6 and Figure 8As shown, to enhance the connection stability between the first connecting portion 510 and the first and second peripheral walls 113 and 123, a first stopper 1131 is provided on the outer side of the first peripheral wall 113, and a second stopper 1231 is provided on the outer side of the second peripheral wall 123. A portion of the first connecting portion 510 abuts and positions the first stopper 1131, while another portion of the first connecting portion 510 abuts and positions the second stopper 1231, thereby preventing the outer cover 500 from being removed from the connector 100. For example, the first limiting portion 1131 is a plurality of first limiting ribs protruding toward the outside of the first circumferential wall 113, and the plurality of first limiting ribs are arranged at circumferential intervals along the first circumferential wall 113; the second limiting portion 1231 is a plurality of second limiting ribs protruding toward the outside of the second circumferential wall 123, and the plurality of second limiting ribs are arranged at circumferential intervals along the second circumferential wall 123; when the first connecting portion 510 is a Velcro, the Velcro is snap-fitted and positioned on the plurality of first limiting ribs and second limiting ribs, thereby preventing the outer cover 500 from falling off the first circumferential wall 113 and the second circumferential wall 123.

[0082] Reference Figure 6 、 Figure 8 and Figure 10 As shown, since the first circumferential wall 113 and the second circumferential wall 123 are both annular structures, the adjacent portions thereof are recessed toward the inside of the connector 100. Therefore, it is difficult for the first connecting portion 510 to be effectively restrained at this position. To address this issue, the connector 100 of the present embodiment further includes a first connecting wall 170 and a second connecting wall 180 arranged along a second direction. The first connecting wall 170 and the second connecting wall 180 extend along a first direction that is perpendicular to the first direction. The ends of the first connecting wall 170 and the second connecting wall 180 are respectively connected to the outer side of the first circumferential wall 113 and the outer side of the second circumferential wall 123. The first connecting wall 170 and the second connecting wall 180 are each provided with at least one third retaining portion 171. Partial portions of the first connecting portion 510 abut against the plurality of third retaining portions 171 to prevent the outer cover 500 from being removed from the connector 100. For example, the first connecting wall 170 can be set to be tangent to the first peripheral wall 113 and the second peripheral wall 123 at both ends, and the second connecting wall 180 can be set to be tangent to the first peripheral wall 113 and the second peripheral wall 123 at both ends, and the third limiting portion 171 is a third limiting rib protruding toward the outside of the first connecting wall 170 or the second connecting wall 180; when the first connecting portion 510 is a Velcro, the Velcro is snap-fitted and positioned on multiple first limiting ribs, second limiting ribs and third limiting ribs, further preventing the outer cover 500 from falling off from the connector 100.

[0083] Reference Figure 8 and Figure 10As shown, in an embodiment of the present invention, the joint 100 includes an outer extension edge 190 arranged around the outer peripheral wall of the joint 100, which increases the strength of the joint 100 and improves the aesthetics of the joint 100; and the first connection part 510 is arranged on the inner side of the outer extension edge 190, and the outer extension edge 190 has a protective effect on the first connection part 510.

[0084] Reference Figure 3 and Figure 4 As shown, an air conditioner according to one embodiment of the present invention includes a housing 2000 and an air intake and exhaust assembly 1000 according to the above embodiment, with the air intake and exhaust assembly 1000 mounted on the housing 2000. It is understood that the air intake and exhaust assembly 1000 is detachably connected to the housing 2000, and the air intake and exhaust assembly 1000 can be integrally mounted on the housing 2000 or detached from the housing 2000. The air intake and exhaust assembly 1000 can be sold separately as an air conditioner accessory or sold together with the air conditioner.

[0085] As an alternative, the air intake and exhaust assembly 1000 may also be fixedly connected to the casing 2000, that is, it forms a non-detachable structure with the casing 2000.

[0086] Since the air conditioner of the embodiment of the present utility model adopts all the technical solutions of the air intake and exhaust assembly 1000 of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

The casing 2000 is provided with an exhaust port 2100 and an air inlet 2200. The exhaust port 2100 and the air inlet 2200 are generally located on the rear panel of the casing 2000. The air from the outdoor environment is sucked into the casing 2000 from the air inlet 2200. After heat exchange, the air is discharged from the casing 2000 from the exhaust port 2100.

[0088] In this embodiment of the present invention, the mobile air conditioner further includes a third mounting bracket 2300 and a fourth mounting bracket 2400 mounted on the housing 2000. The third mounting bracket 2300 is located at the exhaust port 2100, and the fourth mounting bracket 2400 is located at the air inlet 2200. A first telescopic tube 310 is connected to the third mounting bracket 2300. A third end cap 330 is provided at the end of the first telescopic tube 310 near the third mounting bracket 2300. The third mounting bracket 2300 is connected to the third end cap 330 via a snap-fit ​​mechanism, making assembly of the exhaust duct 300 and the housing 2000 more convenient and faster. A second telescopic tube 410 is connected to the fourth mounting bracket 2400. A fourth end cap 430 is provided at the end of the second telescopic tube 410 near the fourth mounting bracket 2400. The third mounting bracket 2300 is connected to the fourth end cap 430 via a snap-fit ​​mechanism, making assembly of the air inlet duct 400 and the housing 2000 more convenient and faster.

[0089] The outer cover 500 has a second connecting portion 520 at one end near the housing 2000. The second connecting portion 520 wraps around the outside of the third mounting seat 2300 and the fourth mounting seat 2400. The second connecting portion 520 can be secured to the third mounting seat 2300 and the fourth mounting seat 2400 by narrowing the opening of the second connecting portion 520. For example, the second connecting portion 520 may be a Velcro strap, a tightening cord, a rubber band, or the like. To further enhance the connection reliability of the second connecting portion 520, the third mounting seat 2300 has a fourth limiting portion 2310, and the fourth mounting seat 2400 has a fifth limiting portion 2410. A portion of the second connecting portion 520 abuts against the fourth limiting portion 2310, while another portion of the second connecting portion 520 abuts against the fifth limiting portion 2410, thereby preventing the outer cover 500 from being dislodged.
