To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

Hereinafter, an air hose joint 1 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 and 5, the air pipe joint 1 includes a ventilation pipe 11, the ventilation pipe 11 is adapted to be inserted into a wall 101, so as to achieve reliable installation of the air pipe joint 1, for example, an installation opening is formed on the wall 101, and the ventilation pipe 11 is adapted to be inserted into the installation opening. A first channel 11b and a second channel 11c which are isolated from each other are defined in the ventilation pipe 11, and the first channel 11b and the second channel 11c are arranged independently from each other and do not interfere with each other, so that the airflow in the first channel 11b cannot directly flow into the second channel 11c, and the airflow in the second channel 11c cannot directly flow into the first channel 11 b; the first passage 11b and the second passage 11c both extend along the axial direction of the ventilation pipe 11, so that when the ventilation pipe 11 is inserted into the wall 101, the first passage 11b and the second passage 11c are respectively communicated with two opposite sides of the wall 101, for example, the first passage 11b is used for communicating the indoor side and the outdoor side of the wall 101, and the second passage 11c is also used for communicating the indoor side and the outdoor side of the wall 101.

It can be understood that the cross-sectional shape of the mounting opening and the cross-sectional shape of the ventilation pipe 11 can be the same or different, and only the ventilation pipe 11 can be ensured to be smoothly inserted into the mounting opening; for example, the mounting opening may be formed as a circular opening, and the ventilation tube 11 is a circular tube; or the mounting opening is formed into a square opening, and the ventilating pipe 11 is a round pipe.

Furthermore, the first passage 11b may extend straight or along a curve (e.g., at least one of an arc, a wavy line, a spiral line, and the like) in the axial direction of the vent pipe 11, and the second passage 11c may extend straight or along a curve in the axial direction of the vent pipe 11, and the following schemes may be included: 1. the first passage 11b and the second passage 11c each extend linearly in the axial direction of the ventilation pipe 11; 2. the first passage 11b and the second passage 11c each extend along an axial curve of the vent pipe 11; 3. the first passage 11b extends linearly in the axial direction of the ventilation pipe 11, and the second passage 11c extends curvilinearly in the axial direction of the ventilation pipe 11; 4. the first passage 11b extends along the axial curve of the vent pipe 11, and the second passage 11c extends linearly along the axial direction of the vent pipe 11.

Wherein, one of the first channel 11b and the second channel 11c can be used for discharging indoor air to the outdoor, and the other can be used for introducing outdoor air to the indoor, for example, the first channel 11b is used for discharging indoor air to the outdoor, the second channel 11c is used for introducing outdoor air to the indoor, or the first channel 11b is used for introducing outdoor air to the indoor, and the second channel 11c is used for discharging indoor air to the outdoor, then the first channel 11b and the second channel 11c can form a bidirectional ventilation channel, so that the ventilation pipe 11 can realize air intake and air exhaust at the same time. Of course, the use manner of the first passage 11b and the second passage 11c is not limited thereto, and for example, the first passage 11b and the second passage 11c may be used both for introducing outdoor air into the room or both for discharging indoor air to the outside.

As shown in fig. 1, 3 and 5, the air pipe joint 1 further includes a first joint 12 and a second joint 13, the first joint 12 and the second joint 13 are both disposed at one axial end of the ventilation pipe 11, a third passage 12a is defined in the first joint 12, the third passage 12a is communicated with the first passage 11b, a fourth passage 13a is defined in the second joint 13, and the fourth passage 13a is communicated with the second passage 11 c. Wherein at least one of the first joint 12 and the second joint 13 is adapted to be fixedly connected with the ventilation pipeline 51, so that the at least one of the first joint 12 and the second joint 13 is communicated with the corresponding ventilation pipeline 51, the following scheme is included: 1. the first connector 12 is adapted to be fixedly connected to the ventilation line 51; 2. the second connector 13 is adapted to be fixedly connected to the ventilation line 51; 3. the first connector 12 and the second connector 13 are adapted to be fixedly connected to the ventilation pipe 51, respectively, in which case the first connector 12 and the second connector 13 can be fixedly connected to different ventilation pipes 51, respectively. From this, be convenient for further guarantee the isolation setting of first passageway 11b and second passageway 11c, can need not to set up other adapter coupling between air pipe connector 1 and the ventilation pipeline 51 simultaneously to air pipe connector 1 and ventilation pipeline 51's quick connection guarantees air pipe connector 1 and ventilation pipeline 51's the leakproofness of being connected.

For example, the opposite sides of the wall 101 may be an outdoor side and an indoor side, and the first joint 12 and the second joint 13 may be both located on the indoor side and may be both located on the outdoor side.

In the following description, the first connector 12 and the second connector 13 are illustrated as being located at the indoor side, and a person skilled in the art can easily understand the scheme that the first connector 12 and the second connector 13 are located at the outdoor side after reading the following description. As shown in fig. 4 and 5, the second joint 13 is fixedly connected to the ventilation pipeline 51, the first channel 11b is used for introducing outdoor air into the room, the second channel 11c is used for discharging indoor air to the outside, so that the first channel 11b and the second channel 11c can form a bidirectional ventilation channel, the ventilation pipeline 11 can simultaneously realize air intake and air exhaust, and when the air pipe joint 1 is applied to the air conditioning equipment 100, an installation opening is formed in the wall 101, so that the air conditioning equipment 100 can discharge indoor air to the outside through the ventilation pipeline 11 and introduce outdoor air into the room.

It can be understood that, when the air conditioning apparatus 100 has a cooling or heating function, the air conditioning apparatus 100 may introduce the outdoor air into the air conditioning apparatus 100 through the ventilation pipe 11 for heat exchange, so as to ensure the cooling/heating efficiency of the air conditioning apparatus 100, avoid reducing the efficiency of the air conditioning apparatus 100 by pumping the indoor air to the outdoor, and increase the energy consumption of the air conditioning apparatus 100; when the air conditioning apparatus 100 discharges indoor air to the outside, it is possible to make the air conditioning apparatus 100 have an air discharging function to discharge indoor dirty air to the outside, improving the comfort of the indoor environment. Of course, the air conditioning device 100 introduces outdoor air into the room, and can also implement the fresh air function of the air conditioning device 100 to improve the indoor air quality.

Compared with the prior art, in order to realize simultaneously with indoor air discharge to outdoor, with outdoor air introduction indoor, need set up a plurality of installing ports on the wall body, lead to the after-sale installation difficulty, user experience is relatively poor for the sales volume is discounted greatly, has effectively reduced the quantity of seting up of installing port in this application, has promoted after-sale installation convenience, can save the installation space of tuber pipe joint 1 simultaneously, is favorable to promoting product experience performance and sales volume.

According to the air pipe joint 1 disclosed by the embodiment of the invention, the first channel 11b and the second channel 11c which are isolated from each other are defined in the ventilation pipe 11, the first channel 11b is communicated with the third channel 12a of the first joint 12, and the second channel 11c is communicated with the fourth channel 13a of the second joint 13, so that the air pipe joint 1 can be provided with a bidirectional ventilation channel, and the convenience of after-sale installation is improved; when the air pipe joint 1 is used in the air-conditioning apparatus 100, it is convenient to implement the corresponding functions of the air-conditioning apparatus 100, and the energy consumption of the air-conditioning apparatus 100 is reduced.

Alternatively, in the example of fig. 1 to 3, the first joint 12 and the second joint 13 may be spaced apart from each other, so as to ensure that the ventilation pipeline 51 has enough installation space for convenient operation when the first joint 12 and the second joint 13 are fixedly connected to the ventilation pipeline 51, respectively.

In some embodiments of the present invention, as shown in fig. 1 and 3, an end of the first passage 11b far from the first joint 12 has a first tuyere 11d, an end of the second passage 11c far from the second joint 13 has a second tuyere 11e, and the first tuyere 11d and the second tuyere 11e are oppositely arranged. When one of the first channel 11b and the second channel 11c is used for discharging indoor air to the outside and the other is used for introducing outdoor air to the inside, one of the first air opening 11d and the second air opening 11e can be used as an air inlet and the other can be used as an air outlet, and because the first air opening 11d and the second air opening 11e are arranged in a back-to-back manner, air flow at the first air opening 11d and the second air opening 11e is prevented from being mixed and short-circulated, for example, air discharged from the air outlet can be prevented from directly flowing to the air inlet, so that the adjusting efficiency of the air conditioning device 100 is low.

For example, in the example of fig. 3, the first tuyere 11d is formed on the left side of the ventilation tube 11, and the second tuyere 11e is formed on the right side of the ventilation tube 11; when the first air opening 11d is used as an air inlet and the second air opening 11e is used as an air outlet, the air flow at the first air opening 11d flows into the first channel 11b from left to right approximately through the first air opening 11d, the air flow at the second air opening 11e flows out of the second channel 11c from left to right approximately through the second air opening 11e, and the air flow discharged by the second air opening 11e is prevented from directly flowing to the first air opening 11d and flowing to the indoor again; similarly, when the first air opening 11d is used as an air outlet and the second air opening 11e is used as an air inlet, the air flow at the first air opening 11d flows out of the first channel 11b through the first air opening 11d from right to left, and the air flow at the second air opening 11e flows into the second channel 11c through the second air opening 11e from right to left, so that the air flow discharged from the first air opening 11d is prevented from flowing into the second air opening 11e directly and flowing into the room again.

In some embodiments of the present invention, as shown in fig. 1 and 3, the first tuyere 11d and the second tuyere 11e are both formed on the peripheral wall of the ventilation tube 11, and the first tuyere 11d and the second tuyere 11e may be oppositely disposed substantially in the radial direction of the ventilation tube 11 so as to realize the back-to-back arrangement of the first tuyere 11d and the second tuyere 11 e.

It is understood that the first tuyere 11d and the second tuyere 11e may be arranged flush with each other or may be arranged offset from each other in the axial direction of the ventilation tube 11. For example, in the example of fig. 1 and 3, the first tuyere 11d and the second tuyere 11e may be disposed flush with each other in the axial direction of the ventilation tube 11, and both end edges of the first tuyere 11d in the axial direction of the ventilation tube 11 may be located on the same cross section of the ventilation tube 11 as corresponding edges of the second tuyere 11e in the axial direction of the ventilation tube 11, respectively; wherein the first tuyere 11d and the second tuyere 11e may be symmetrically arranged about the central axis of the ventilation tube 11.

In some embodiments of the present invention, as shown in fig. 1 and 3, the vent tube 11 has a first wind-guiding portion 110A and a second wind-guiding portion 110B, in the axial direction of the ventilation pipe 11, the first wind guiding part 110A is arranged at one end of the first tuyere 11d far away from the first joint 12, the second wind guiding part 110B is arranged at one end of the second tuyere 11e far away from the second joint 13, the first wind guiding part 110A and the second wind guiding part 110B both extend along the direction inclined relative to the axial direction of the ventilation pipe 11, so that, in the axial direction of the ventilation pipe 11, the first wind-guiding portion 110A can block at least part of the first passage 11B, the second wind-guiding portion 110B can block at least part of the second passage 11c, therefore, the first wind guide part 110A and the second wind guide part 110B can separate the air flow at the first tuyere 11d and the second tuyere 11e, so as to further ensure the isolation arrangement of the first channel 11B and the second channel 11 c.

The first air guiding part 110A and the second air guiding part 110B both extend along a direction inclined relative to the axial direction of the ventilation pipe 11, and it can be understood that a non-zero included angle exists between the extending direction of the first air guiding part 110A and the axial direction of the ventilation pipe 11, and a non-zero included angle exists between the extending direction of the second air guiding part 110B and the axial direction of the ventilation pipe 11.

Optionally, in the example of fig. 3, at least one of the first wind-guiding portion 110A and the second wind-guiding portion 110B is arranged perpendicular to the axial direction of the ventilation pipe 11, and at least one of the first wind-guiding portion 110A and the second wind-guiding portion 110B extends in a direction perpendicular to the axial direction of the ventilation pipe 11, which includes the following solutions: the first air guiding part 110A is arranged perpendicular to the axial direction of the ventilation pipe 11, the second air guiding part 110B is arranged perpendicular to the axial direction of the ventilation pipe 11, or both the first air guiding part 110A and the second air guiding part 110B are arranged perpendicular to the axial direction of the ventilation pipe 11. Therefore, on the premise of ensuring that the first channel 11b and the second channel 11c are arranged in an isolated mode, the first air port 11d and the second air port 11e are prevented from having large wind resistance, and smooth air flow is ensured.

In some embodiments of the present invention, as shown in fig. 1 and 3, the ventilation pipe 11 includes a pipe body 111 and a first partition 112, the pipe body 111 is adapted to be inserted through the wall 101, a passage 11a is defined in the pipe body 111, the first partition 112 is disposed in the pipe body 111, and the first partition 112 divides the passage 11a into a first passage 11b and a second passage 11c, so that two ends of the first partition 112 may extend to two axial ends of the pipe body 111, respectively. Therefore, the structure of the ventilation pipe 11 is simplified, and the processing of the ventilation pipe 11 is facilitated.

Of course, the structural arrangement of the vent tube 11 is not limited thereto; for example, the ventilation tube 11 may be configured such that a plurality of tubes are arranged side by side, with one tube defining a first passage 11b therein and one of the remaining tubes defining a second passage 11c therein.

It is to be understood that the magnitude relationship between the cross-sectional area of the first passage 11b and the cross-sectional area of the second passage 11c is not particularly limited, i.e., the cross-sectional area of the first passage 11b may be greater than, or less than, or equal to the cross-sectional area of the second passage 11 c; in the axial direction of the ventilation pipe 11, the cross-sectional area of the first passage 11b may be kept constant at all times, or the first passage 11b is a variable cross-sectional passage 11 a; the cross-sectional area of the second passage 11c may be kept constant all the time in the axial direction of the ventilation tube 11, or the second passage 11c may be a variable cross-sectional passage 11 a.

For example, in the example of fig. 1 and 3, the cross-sectional area of the passage 11a is always constant in the axial direction of the duct 11, the duct 11 is of a straight tube structure, i.e., the central axis of the duct 11 is a straight line, the first partition plate 112 is formed of a flat plate structure, and the first partition plate 112 is of an equal thickness structure, the first partition plate 112 being arranged in the axial direction of the duct 11 such that the cross-sectional area of the first passage 11b is equal to the cross-sectional area of the second passage 11 c. Of course, the ventilation duct 11 may also be of a bent pipe structure.

In some embodiments of the present invention, as shown in fig. 1 to 3, the air duct joint 1 further includes a protective net 14, and the protective net 14 is respectively disposed in the first passage 11b and the second passage 11c, so that the protective net 14 can shield the first passage 11b and the second passage 11c to prevent rats, insects, etc. from entering a room through the first passage 11b and the second passage 11c, so as to achieve a certain protection effect.

It is understood that the protection net 14 corresponding to the first channel 11b and the protection net 14 corresponding to the second channel 11c may be integrally formed or may be separately formed. In the axial direction of the ventilation duct 11, the protection net 14 corresponding to the first passage 11b and the protection net 14 corresponding to the second passage 11c may be disposed flush with each other or may be disposed offset from each other. For example, in the example of fig. 3, in the axial direction of the ventilation pipe 11, the protection net 14 corresponding to the first passage 11b and the protection net 14 corresponding to the second passage 11c may be arranged flush with each other, and then the protection net 14 corresponding to the first passage 11b and the protection net 14 corresponding to the second passage 11c may be located on the same cross section of the ventilation pipe 11, where the protection net 14 corresponding to the first passage 11b and the protection net 14 corresponding to the second passage 11c are an integral piece.

In addition, in the axial direction of the ventilation pipe 11, the arrangement position of the protection net 14 corresponding to the first passage 11b may be selected according to actual requirements, and the arrangement position of the protection net 14 corresponding to the second passage 11c may be selected according to actual requirements. For example, in the example of fig. 3, the protection net 14 corresponding to the first channel 11b is arranged at the end of the first channel 11b adjacent to the first joint 12, so that the protection net 14 has a larger operation space when being installed, so that the protection net 14 can be conveniently installed, and the protection net 14 corresponding to the second channel 11c is arranged at the end of the second channel 11c adjacent to the second joint 13, so that the installation of the protection net 14 is also facilitated.
