[0034] like Figures 1 to 6 As shown, the exhaust assembly is applied to the condensation water pipe of the air-conditioning unit, and the exhaust assembly includes: a connecting pipe 10 and a sealing cover assembly 20.

[0035] The connecting pipe 10 includes an air pipe 11 and an outer cover 12. The outer cover 12 is arranged at one end of the air pipe 11, and the outer cover 12 has a accommodating space, which is connected to the interior of the air pipe 11. The air pipe 11 is used to be connected to the condensate water pipe; the sealing assembly 20 includes a sealing tube 21 and a sealing cap 22. The sealing cap 22 is arranged at the first end of the sealing tube 21, and the sealing cap 22 blocks the first end of the sealing tube 21. The sealing tube 21 is embedded in the accommodating space of the outer cover 12, and the sealing tube 21 is detachably connected to the inner wall of the outer cover 12. There is a gap between the sealing tube 21 and the inner wall of the outer cover 12, and the gap is respectively connected to the interior of the air pipe 11 and the outside of the air pipe 11.

[0036] In the embodiment of the present application, since the connecting pipe 10 includes the air pipe 11 and the outer cover 12, the outer cover 12 is arranged at one end of the air pipe 11, and the outer cover 12 has a accommodating space, which is connected to the interior of the air pipe 11. Therefore, the air pipe 11 can be connected to the condensation water pipe of the air-conditioning unit, so that the interior of the condensation water pipe can be connected to the outside through the air pipe 11 and the outer cover 12, so that the external gas can enter the condensation water pipe to balance the air pressure in the condensation water pipe, ensuring that the condensed water in the condensation water pipe can be discharged smoothly. Since the sealing assembly 20 includes a sealing tube 21 and a sealing cap 22, the sealing cap 22 is arranged at the first end of the sealing tube 21, and the sealing cap 22 blocks the first end of the sealing tube 21, the sealing tube 21 is embedded in the accommodating space of the outer cover 12, and there is a gap between the sealing tube 21 and the inner wall of the outer cover 12, and the gap is respectively connected to the inside of the air pipe 11 and the outside of the air pipe 11. Therefore, once the air pipe 11 is connected to the condensed water pipe, the inside of the condensed water pipe is connected to the air pipe 11, and the gap between the inside of the air pipe 11 and the inner wall of the sealing tube 21 and the outer cover 12 is The gap is connected, and the gap is connected with the outside of the trachea 11, so that the inside of the trachea 11 is connected with the outside of the trachea 11 through the gap, and then the inside of the condensation water pipe is connected with the outside of the trachea 11 through the gap, and the external gas can enter the condensation water pipe, and the gap can prevent most dust and small insects from entering the trachea 11, thereby preventing most dust and small insects from entering the condensation water pipe and affecting the patency of the condensation water pipe, and the presence of the sealing cap 22 can also prevent most dust and small insects from entering the trachea 11. Since the sealing tube 21 is detachably connected to the inner wall of the outer cover 12, it is convenient to install the sealing tube 21 in the accommodation space of the outer cover 12, and it is also convenient to take the sealing tube 21 out of the accommodation space of the outer cover 12 for maintenance or replacement. That is, in the embodiment of the present application, the outer cover 12 is provided to be connected with the air pipe 11, and the sealing tube 21 is embedded in the accommodating space of the outer cover 12, and there is a gap between the sealing tube 21 and the inner wall of the outer cover 12, so that the sealing cap 22 can prevent dust and small insects from entering the sealing tube 21, and the gap between the sealing tube 21 and the outer cover 12 can prevent most dust and small insects from entering the outer cover 12, thereby preventing most dust and small insects from entering the air pipe 11 and then entering the condensation water pipe. That is, through the exhaust component provided in the embodiment of the present application, while ensuring that the condensation water pipe can drain smoothly, most dust and small insects can be prevented from entering the condensation water pipe as much as possible, thereby improving the performance of the air-conditioning unit.

[0037] It should be noted that the outer cover 12 can be a cylindrical structure with openings at both ends. One end of the outer cover 12 is sleeved on one end of the trachea 11 and is sealed. The opening at the other end of the outer cover 12 is open, and the interior of the outer cover 12 is the accommodation space of the outer cover 12. When installing the capping tube 21, the capping tube 21 can be directly embedded into the interior of the outer cover 12 through the opening at the other end of the outer cover 12, that is, embedded into the accommodation space of the outer cover 12, and the capping tube 21 and the outer cover 12 are detachably connected, thereby ensuring that the outer cover 12 can fix the capping tube 21 and avoiding the problem that the capping tube 21 is easily separated from the outer cover 12. In addition, there is a gap between the capping tube 21 and the inner wall of the outer cover 12, and the gap is connected to the interior of the trachea 11, and the gap is connected to the outside of the trachea 11, so that the external gas can enter the trachea 11 through the gap.

[0038] In addition, in the embodiment of the present application, when the sealing tube 21 is embedded in the accommodating space of the outer cover 12, there is a gap between the sealing cap 22 and the end of the outer cover 12, and there is a gap between the tube wall of the sealing tube 21 and the inner wall of the outer cover 12, so that the gap is connected to the gap, so that the gap is connected to the outside of the air pipe 11.

[0039] In addition, in the embodiment of the present application, there are many ways to detachably connect the capping tube 21 to the inner wall of the outer cover 12, which are specifically described by taking the following as examples:

[0040] Method (1): At least one first snap-in hole 121 is provided on the outer wall of the outer cover 12, and at least one first elastic snap-in 211 is provided on the outer wall of the sealing tube 21. The first elastic snap-in 211 is snap-fitted to the first snap-in hole 121 so that the sealing tube 21 can be detachably connected to the inner wall of the outer cover 12.

[0041] Since at least one first snap-fit ​​hole 121 is provided on the outer wall of the outer cover 12, and at least one first elastic snap-fit ​​buckle 211 is provided on the outer wall of the sealing tube 21, when the sealing tube 21 is embedded in the accommodating space of the outer cover 12, the first elastic snap-fit ​​buckle 211 can be squeezed by the inner wall of the outer cover 12, so that the first elastic snap-fit ​​buckle 211 contracts. Once the first elastic snap-fit ​​buckle 211 is moved to the first snap-fit ​​hole 121, the inner wall of the outer cover 12 releases the squeezing of the first elastic snap-fit ​​buckle 211, so that the first elastic snap-fit ​​buckle 211 stretches and is embedded in the first snap-fit ​​hole 121, so that the sealing tube 21 is detachably connected to the outer wall of the outer cover 12. When it is necessary to remove the sealing tube 21 from the outer cover 12, force can be applied to the sealing tube 21, so that the first elastic snap-fit ​​buckle 211 is disengaged from the first snap-fit ​​hole 121, and the sealing tube 21 can be removed from the outer cover 12. That is, by providing the first snap-fitting hole 121 on the outer wall of the outer cover 12 and the first elastic buckle 211 on the outer wall of the sealing tube 21 , the sealing tube 21 can be detachably connected to the inner wall of the outer cover 12 .

[0042] It should be noted that the number of the first elastic buckles 211 can be set according to actual needs, and the number of the first snap holes 121 can be equal to the number of the first elastic buckles 211. For example, the number of the first elastic buckles 211 is 2, and the number of the first snap holes 121 is 2. For another example, the number of the first elastic buckles 211 is 4, and the number of the first snap holes 121 is 4. The specific number of the first elastic buckles 211 is not limited in the embodiment of the present application.

[0043] In addition, when there are multiple first elastic buckles 211, the multiple first elastic buckles 211 can be spaced apart along the circumferential direction of the sealing tube 21, and correspondingly, the multiple first snap-fit ​​holes 121 are spaced apart along the circumferential direction of the outer cover 12.

[0044] In addition, in the embodiment of the present application, the first clamping hole 121 passes through the outer wall of the outer cover 12 , so that after the first elastic buckle 211 enters the accommodating space of the outer cover 12 , the first elastic buckle 211 can be embedded in the first clamping hole 121 .

[0045] In addition, in some embodiments, a notch 122 is provided at the end of the outer cover 12 away from the air pipe 11 , and in the axial direction of the outer cover 12 , the notch 122 is opposite to a first snap-in hole 121 , and the notch 122 is used to indicate that the sealing tube 21 is correctly installed in the outer cover 12 .

[0046] Since the end of the outer cover 12 away from the air pipe 11 is provided with a notch 122, and in the axial direction of the outer cover 12, the notch 122 is opposite to a first snap-fit ​​hole 121, when the capping tube 21 is inserted into the accommodating space of the outer cover 12, a first elastic snap 211 on the capping tube 21 can be positioned at a corresponding position, and then force is applied to the capping tube 21, so that the capping tube 21 is inserted into the accommodating space of the outer cover 12, and the first elastic snap 211 on the capping tube 21 is inserted into the corresponding first snap-fit ​​hole 121. That is, by providing the notch 122 on the outer cover 12, when the capping tube 21 is inserted into the outer cover 12, the operator can find the notch 122, and then insert the corresponding first elastic snap-fit ​​hole into the outer cover 12 along the position of the notch 122, so as to ensure that the capping tube 21 is correctly installed in the outer cover 12, and the existence of the notch 122 can also play a guiding role, which can facilitate the operator to quickly insert the capping tube 21 into the outer cover 12.

[0047] It should be noted that a marking point can be set on the sealing cap 22, and the marking point corresponds to the notch 122 on the outer cover 12, so that when the operator embeds the sealing tube 21 into the outer cover 12, the marking point can be first made to correspond to the notch 122 on the outer cover 12, and then force can be applied to the sealing tube 21 to make the sealing tube 21 embedded in the outer cover 12, ensuring that the sealing tube 21 can be correctly installed.

[0048] In addition, in some embodiments, the first elastic buckle 211 is inclined along the direction from the first elastic buckle 211 to the covering cap 22, and in the inner wall of the outer cover 12, part of the inner wall between one end of the outer cover 12 and the first snap-fit ​​hole 121 is inclined along the direction from one end of the outer cover 12 to the first snap-fit ​​hole 121.

[0049] With such a configuration, when the capping tube 21 is inserted into the outer cover 12, the first elastic buckle 211 contacts the inner wall of the outer cover 12, and the first elastic buckle 211 is inclined, and the inner wall of the outer cover 12 is inclined, so that when a force is applied to the capping tube 21, the first elastic buckle 211 can be inclined due to its own inclination and the inclination of the inner wall of the outer cover 12, and the first elastic buckle 211 is subject to less resistance, so that the capping tube 21 is easily inserted into the accommodation space of the outer cover 12. That is, by setting the first elastic buckle 211 to be inclined in the direction from the first elastic buckle 211 to the capping cap 22, and setting the inner wall of the outer cover 12 to be inclined, it is easy to install the capping tube 21 in the accommodation space of the outer cover 12.

[0050] Method (2): At least one second elastic clip (not shown in the figure) is provided on the inner wall of the outer cover 12, and at least one second snap-in hole is provided on the tube wall of the sealing tube 21. The second elastic clip is snap-connected to the second snap-in hole, so that the sealing tube 21 can be detachably connected to the inner wall of the outer cover 12.

[0051] Since at least one second elastic buckle is provided on the outer wall of the outer cover 12 and at least one second snap-fitting hole is provided on the outer wall of the capping tube 21, when the capping tube 21 is embedded in the accommodation space of the outer cover 12, the second elastic buckle can be squeezed by the outer wall of the capping tube 21, so that the second elastic buckle shrinks. Once the second elastic buckle is moved to the second snap-fitting hole, the outer wall of the capping tube 21 releases the squeezing of the second elastic buckle, so that the second elastic buckle stretches and is embedded in the second snap-fitting hole, so that the capping tube 21 is detachably connected to the outer wall of the outer cover 12. When it is necessary to remove the capping tube 21 from the outer cover 12, force can be applied to the capping tube 21, so that the second elastic buckle is disengaged from the second snap-fitting hole, and the capping tube 21 can be removed from the outer cover 12. That is, by providing the second elastic buckle on the outer wall of the outer cover 12 and the second snap-fitting hole on the outer wall of the capping tube 21, the capping tube 21 can be easily detachably connected to the inner wall of the outer cover 12.

[0052] It should be noted that the number of the second elastic buckles can be set according to actual needs, and the number of the second snap-fit ​​holes can be equal to the number of the second elastic buckles. For example, the number of the second elastic buckles is 3, and the number of the second snap-fit ​​holes is 3. For another example, the number of the second elastic buckles is 4, and the number of the second snap-fit ​​holes is 4. The specific number of the second elastic buckles is not limited in the embodiments of the present application.

[0053] In addition, when there are multiple second elastic buckles, the multiple second elastic buckles can be spaced apart along the circumferential direction of the outer cover 12, and correspondingly, the multiple second snap-fit ​​holes are spaced apart along the circumferential direction of the sealing tube 21.

[0054] In addition, in the embodiment of the present application, the second snap-fit ​​hole penetrates the tube wall of the sealing tube 21 , so that after the sealing tube 21 enters the outer cover 12 , the second elastic buckle can be embedded in the second snap-fit ​​hole.

[0055] In addition, in some embodiments, a fixed tube 101 is provided in the accommodating space of the outer cover 12, the fixed tube 101 is connected with the air pipe 11, the sealing tube 21 is sleeved on the fixed tube 101, or the sealing tube 21 is embedded in the fixed tube 101; a first air hole 212 is provided on the tube wall of the sealing tube 21, a second air hole 123 is provided on the outer wall of the outer cover 12, and the first air hole 212 is connected with the second air hole 123.

[0056] Since the fixing tube 101 is provided in the accommodation space of the outer cover 12, the fixing tube 101 is communicated with the air pipe 11, and the capping tube 21 is sleeved on the fixing tube 101, or the capping tube 21 is embedded in the fixing tube 101, the fixing tube 101 can also play a certain role in fixing the capping tube 21, further avoiding the problem that the capping tube 21 may shake in the outer cover 12. In addition, by providing the fixing tube 101 and sleeve the capping tube 21 on the fixing tube 101, it is also possible to prevent a large amount of dust in the accommodation space of the outer cover 12 from entering the air pipe 11 through the second air hole 123. Since a first air hole 212 is provided on the tube wall of the covering tube 21, and a second air hole 123 is provided on the outer wall of the outer cover 12, the first air hole 212 is connected with the second air hole 123. Therefore, after the covering tube 21 is embedded in the accommodating space of the outer cover 12, the covering tube 21 is sleeved on the fixed tube 101, and the gap between the covering tube 21 and the inner wall of the outer cover 12 can make the first air hole 212 connected with the second air hole 123, so that the gas outside the air pipe 11 can flow into the outer cover 12 through the second air hole 123, and then flow into the covering tube 21 through the first air hole 212. Once the gas enters the covering tube 21, it can flow into the fixed tube 101 and then into the air pipe 11. If the air pipe 11 is installed on the condensation water pipe of the air-conditioning unit, the gas can enter the condensation water pipe to balance the air pressure in the condensation water pipe, so that the condensation water pipe can drain smoothly. That is, by setting the fixed tube 101, setting the first air hole 212 on the sealing tube 21, and setting the second air hole 123 on the outer cover 12, not only the stability of the sealing tube 21 can be further improved, but also dust can be prevented from entering the air pipe 11 and affecting the drainage of the condensate pipe.

[0057] It should be noted that the number of the first air holes 212 can be set according to actual needs. For example, the number of the first air holes 212 is 5, and for another example, the number of the first air holes 212 is 7. The specific number of the first air holes 212 is not limited in the embodiment of the present application. In addition, the first air holes 212 can extend along the axial direction of the sealing tube 21, and the shape of the first air holes 212 can be set according to actual needs. For example, the shape of the first air holes 212 is a rectangle, and for another example, the shape of the first air holes 212 is an ellipse. The specific shape of the first air holes 212 is not limited in the embodiment of the present application. In addition, when the number of the first air holes 212 is multiple, the multiple first air holes 212 can be spaced apart and distributed along the circumferential direction of the sealing tube 21.

[0058] In addition, the number of the second air holes 123 can be set according to actual needs, for example, the number of the second air holes 123 is 4, and for another example, the number of the second air holes 123 is 7. The specific number of the second air holes 123 is not limited in the embodiment of the present application. In addition, the second air holes 123 can extend along the axial direction of the sealing tube 21, and the shape of the second air holes 123 can be set according to actual needs. For example, the shape of the second air holes 123 is a rectangle, and for another example, the shape of the second air holes 123 is an ellipse. The specific shape of the second air holes 123 is not limited in the embodiment of the present application. In addition, when the number of the second air holes 123 is multiple, the multiple second air holes 123 can be spaced and distributed along the circumferential direction of the outer cover 12.

[0059] In addition, in the embodiment of the present application, when the capping tube 21 is embedded in the outer cover 12, the fixed tube 101 can be embedded in the capping tube 21, and the length of the fixed tube 101 is less than the length of the capping tube 21, so that the fixed tube 101 only occupies part of the space inside the capping tube 21. In addition, once the fixed tube 101 is embedded in the capping tube 21, the first air hole 212 can overlap with the fixed tube 101. Of course, the first air hole 212 can also completely avoid the fixed tube 101, that is, after the fixed tube 101 is extended into the embedding tube, the fixed tube 101 will not overlap with the first air hole 212, which can ensure that the first air hole 212 transmits air flow more smoothly.

[0060] In addition, in some embodiments, along the axial direction of the outer cover 12 , the first air hole 212 and the second air hole 123 are offset from each other, and along the circumferential direction of the outer cover 12 , the first air hole 212 and the second air hole 123 are offset from each other.

[0061] With such a configuration, once dust enters the outer cover 12 through the second air hole 123, the dust will be blocked by the outer wall of the capping tube 21, preventing the dust from directly entering the capping tube 21 through the first air hole 212. That is, by displacing the first air hole 212 and the second air hole 123 in the circumferential direction of the outer cover 12 and in the axial direction of the outer cover 12, dust that enters the outer cover 12 through the second air hole 123 can be effectively prevented from entering the capping tube 21, thereby preventing dust from entering the air pipe 11.

[0062] It should be noted that, when the number of the first air holes 212 and the number of the second air holes 123 are both plural, each first air hole 212 is offset from the second air hole 123 in the circumferential direction and the axial direction of the outer cover 12 .

[0063] In addition, in some embodiments, the second air hole 123 extends along the axial direction of the outer cover 12 to an end of the outer cover 12 close to the air pipe 11 .

[0064] Since the second air hole 123 extends along the circumferential direction of the outer cover 12 to the end of the outer cover 12 close to the trachea 11, it is equivalent to that the second air hole 123 extends from the end of the outer cover 12 close to the trachea 11, so that once dust enters the outer cover 12 through the second air hole 123, the dust will fall to the end of the outer cover 12 close to the trachea 11 due to its own gravity, and the second air hole 123 extends to the end of the outer cover 12 close to the trachea 11, so that the dust can easily flow out of the outer cover 12 through the second air hole 123, avoiding the problem of dust accumulation in the outer cover 12. That is, by setting the second air hole 123 to extend along the axial direction of the outer cover 12 to the end of the outer cover 12 close to the trachea 11, the problem of dust accumulation in the outer cover 12 can be effectively avoided, ensuring that there is less dust in the outer cover 12, thereby avoiding the problem of dust entering the trachea 11 and affecting the drainage of the condensate pipe.

[0065] In addition, in some embodiments, the width of the second air hole 123 is less than or equal to 3 mm, and the width of the second air hole 123 is: the distance between opposite hole walls of the second air hole 123 along the circumferential direction of the outer cover 12 .

[0066] Since the width of the second air hole 123 is less than or equal to 3 mm, once the insect flies to the second air hole 123, the smaller width of the second air hole 123 can effectively block the insect and prevent the insect from entering the outer cover 12 through the second air hole 123. Moreover, the smaller width of the second air hole 123 can also prevent dust with larger particles from entering the outer cover 12. That is, by setting the width of the second air hole 123 to be less than or equal to 3 mm, it is helpful to improve the cleanliness of the outer cover 12, so that there is less dust and insects in the outer cover 12, and thus the outer cover 12 is cleaner.

[0067] It should be noted that the width of the second air hole 123 can be any value less than or equal to 3 mm, for example, the width of the second air hole 123 is 3 mm, for another example, the width of the second air hole 123 is 2 mm, and for another example, the width of the second air hole 123 is 1 mm. The specific value of the width of the second air hole 123 is not limited in the embodiment of the present application.

[0068] In addition, in the embodiment of the present application, the width of the first air hole 212 may be less than or equal to 3 mm, and the width of the first air hole 212 is: the distance between the opposite hole walls of the first air hole 212 along the circumferential direction of the sealing tube 21 .

[0069] In addition, in some embodiments, the distance between the sealing cap 22 and an end of the outer cover 12 away from the air pipe 11 is less than or equal to 2 mm.

[0070] Since the distance between the sealing cap 22 and the end of the outer cover 12 away from the trachea 11 is less than or equal to 2 mm, once the insects fly to the sealing cap 22, the smaller width of the second air hole 123 can effectively block the insects and prevent the insects from entering the outer cover 12 through the second air hole 123. Moreover, the smaller width of the second air hole 123 can also prevent dust with larger particles from entering the outer cover 12. That is, by setting the width of the second air hole 123 to be less than or equal to 3 mm, it is helpful to improve the cleanliness of the outer cover 12, so that there are less dust and insects in the outer cover 12, and thus the outer cover 12 is cleaner.

[0071] It should be noted that the distance between the sealing cap 22 and the end of the outer cover 12 away from the trachea 11 can be any value less than or equal to 2 mm. For example, the distance between the sealing cap 22 and the end of the outer cover 12 away from the trachea 11 is 2 mm. For another example, the distance between the sealing cap 22 and the end of the outer cover 12 away from the trachea 11 is 1.5 mm. For another example, the distance between the sealing cap 22 and the end of the outer cover 12 away from the trachea 11 is 1 mm. The specific value of the distance between the sealing cap 22 and the end of the outer cover 12 away from the trachea 11 is not limited in the embodiments of the present application.

[0072] In addition, in the embodiment of the present application, along the axial direction of the capping tube 21, the projection of the capping cap 22 covers the projection of the outer cover 12. That is, along the axial direction of the capping tube 21, the projection of the outer cover 12 is located inside the projection of the capping cap 22, so that after the capping tube 21 is embedded in the outer cover 12, the capping cap 22 is equivalent to effectively covering the end of the outer cover 12, preventing dust from falling directly into the outer cover 12 along the axial direction of the outer cover 12.

[0073] Additionally, in some embodiments, the closure cap 22 is conical in shape.

[0074] Since the shape of the sealing cap 22 is conical, once dust falls on the sealing cap 22, the dust can quickly slide off the sealing cap 22 due to its own gravity, thereby preventing dust from accumulating on the sealing cap 22. That is, by setting the shape of the sealing cap 22 to be conical, the cleanliness of the sealing cap 22 can be effectively ensured.

[0075] Of course, in the embodiment of the present application, the shape of the sealing cap 22 can also be other shapes, for example, the shape of the sealing cap 22 is a triangular pyramid. The specific shape of the sealing cap 22 is not limited in the embodiment of the present application.

[0076] In addition, in some embodiments, the trachea 11 includes a first tube 111 and a second tube 112, the first tube 111 is connected to the second tube 112, the outer cover 12 is connected to the first tube 111, and there is an angle between the first tube 111 and the second tube 112, and the angle ranges from 45° to 60°.

[0077] Through such a setting, the size of the air pipe 11 in the circumferential direction of the air pipe 11 can be reduced, that is, the size of the air pipe 11 in the vertical direction is smaller, which is equivalent to reducing the vertical height of the air pipe 11. Therefore, when installing the exhaust assembly, the exhaust assembly provided by the embodiment of the present application can also be installed on the condensate water pipe with a smaller installation space. That is, by setting an angle between the first pipe 111 and the second pipe 112, the range of the angle is: 45° to 60°, which can effectively improve the application range of the exhaust assembly, so that the exhaust assembly can be applied to most installation environments, thereby facilitating the market promotion of the exhaust assembly.

[0078] It should be noted that the angle between the first tube 111 and the second tube 112 can be any value between 45° and 60°. For example, the angle between the first tube 111 and the second tube 112 is 45°. For another example, the angle between the first tube 111 and the second tube 112 is 50°. For another example, the angle between the first tube 111 and the second tube 112 is 55°. For another example, the angle between the first tube 111 and the second tube 112 is 60°. The specific value of the angle between the first tube 111 and the second tube 112 is not limited in the embodiment of the present application. Among them, the angle between the first tube 111 and the second tube 112 is: the angle between the axis of the first tube 111 and the axis of the second tube 112.

[0079] In addition, in some embodiments, at least one cutting groove 001 is provided on the outer wall of the trachea 11 along the circumferential direction of the trachea 11 , and the cutting groove 001 is used to circumferentially cut the trachea 11 along the cutting groove 001 , so that the trachea 11 can be cut off.

[0080] Since at least one cutting groove 001 is provided on the outer wall of the air pipe 11 along the circumferential direction of the air pipe 11, during the process of installing the exhaust assembly, if the air pipe 11 is too long and it is inconvenient to install the exhaust assembly, the air pipe 11 can be directly cut along the cutting groove 001 to reduce the length of the air pipe 11. That is, by providing the cutting groove 001 on the outer wall of the air pipe 11, it is convenient to cut off the air pipe 11 when it is inconvenient to install the exhaust assembly, thereby facilitating the installation of the exhaust assembly.

[0081] It should be noted that the number of cutting grooves 001 can be set according to actual needs, for example, the number of cutting grooves 001 is 1, for another example, the number of cutting grooves 001 is 2, and for another example, the number of cutting grooves 001 is 3. The specific number of cutting grooves 001 is not limited in the embodiment of the present application. In addition, when the number of cutting grooves 001 is multiple, the multiple cutting grooves 001 are spaced apart and distributed along the axial direction of the trachea 11.

[0082] In addition, in the embodiment of the present application, the cutting groove 001 can surround the outer wall of the trachea 11 along the circumferential direction of the trachea 11, so that the trachea 11 can be easily cut along the cutting groove 001. Of course, the cutting groove 001 can also surround only part of the outer wall along the circumferential direction of the trachea 11. The embodiment of the present application does not limit the specific form of the cutting groove 001.

[0083] In addition, in the embodiment of the present application, when the trachea 11 includes the first tube 111 and the second tube 112, the cutting groove 001 can be provided on the outer wall of the first tube 111, and of course, the cutting groove 001 can also be provided on the outer wall of the second tube 112, and of course, the cutting groove 001 can also be provided on the outer wall of the first tube 111 and the outer wall of the second tube 112 at the same time. This embodiment of the present application is not limited here.

That is, in the embodiment of the present application, the outer cover 12 is provided to be connected with the air pipe 11, and the sealing tube 21 is embedded in the accommodating space of the outer cover 12, and there is a gap between the sealing tube 21 and the inner wall of the outer cover 12, so that the sealing cap 22 can prevent dust and small insects from entering the sealing tube 21, and the gap between the sealing tube 21 and the outer cover 12 can prevent most dust and small insects from entering the outer cover 12, thereby preventing most dust and small insects from entering the air pipe 11 and then entering the condensation water pipe. That is, through the exhaust component provided in the embodiment of the present application, while ensuring that the condensation water pipe can drain smoothly, most dust and small insects can be prevented from entering the condensation water pipe as much as possible, thereby improving the performance of the air-conditioning unit.
