Abstract
Description
[Technical Field]
[0001] The present invention relates to a heat exhaust pipe coupling device, and more particularly to a heat exhaust pipe coupling device for a portable air conditioner. [Background technology]
[0002] To ensure mobility during use, portable air conditioners typically employ a heat exhaust pipe, which is a compressible hose, one end of which is installed inside the housing of the portable air conditioner. When the portable air conditioner is not in use, the user stores the heat exhaust pipe inside the housing, but when in use, the user can pull the heat exhaust pipe out of the housing and connect it to the outdoors, allowing the heat generated by the portable air conditioner to be exhausted outdoors.
[0003] When a user pulls out the heat exhaust pipe, a certain amount of force is required to extend it. However, in conventional portable air conditioners, the heat exhaust pipe is simply attached to the inner wall surface of the housing. Therefore, if a user pulls out the heat exhaust pipe with excessive force, the entire pipe will move rather than being extended, which is very inconvenient to use.
[0004] In view of this situation, providing a better solution has become an urgent problem to be solved in this technical field. Summary of the Invention
[0005] The present invention aims to provide a heat exhaust pipe connection device for a portable air conditioner that fixes one end of the heat exhaust pipe to the housing of the portable air conditioner, making it easier to pull the heat exhaust pipe out of the housing.
[0006] To achieve the above object, the present invention provides the following heat exhaust pipe connecting device for a portable air conditioner. A heat exhaust pipe connecting device for a mobile air conditioner having a housing, The housing includes: a heat dissipation hole formed on a surface of the housing, the heat dissipation hole communicating the inside and outside of the housing; a heat transfer member provided within the housing and having an intake port and an exhaust port; an expandable heat exhaust pipe, one end of which is connected to the exhaust port of the heat conduction member and the other end of which can selectively protrude from the heat radiation hole, and a plurality of wrinkles are formed on the surface of the heat exhaust pipe when the heat exhaust pipe contracts; a fixing member that penetrates one side surface of the housing and is capable of engaging with the crease.
[0007] The advantage of this invention is that the fixing member is provided, and when the fixing member approaches the heat exhaust pipe, it engages with the wrinkles on the heat exhaust pipe to fix one end of the heat exhaust pipe to the fixing member, so that when a user pulls the heat exhaust pipe out of the housing, the one end of the heat exhaust pipe is fixed to the fixing member, preventing the entire heat exhaust pipe from being pulled out or becoming displaced due to the user applying excessive force.

[0009] As shown in Figures 1 to 3, the present invention relates to a heat exhaust pipe connection device for a mobile air conditioner, and includes a housing 10, a heat conduction member 20, a heat exhaust pipe 30, and a fixing member 40, and may optionally further include a positioning pipe 50.
[0010] As shown in FIGS. 1 to 3 and 5 , the housing 10 has heat dissipation holes 11 formed on its surface, connecting the interior and exterior. The heat conduction member 20 is provided within the housing 10 and has an air intake port 21 and an air exhaust port 22. The heat exhaust pipe 30 is an expandable pipe, one end of which is connected to the air exhaust port 22 of the heat conduction member 20, and the other end of which can selectively protrude through the heat dissipation hole 11. When the heat exhaust pipe 30 contracts, multiple wrinkles 31 are formed on its surface. Specifically, when the heat exhaust pipe 30 contracts, both ends are pushed toward the center, which applies force to the pipe wall, causing it to fold and form a state in which multiple sheets are overlapped. In other words, these wrinkles 31 are formed so as to extend perpendicular to the longitudinal direction of the heat exhaust pipe 30 or so as to surround the periphery of the heat exhaust pipe 30.
[0011] 3 and 5 to 7, the fixing member 40 penetrates one side surface of the housing 10, is capable of engaging with the wrinkles 31 of the heat exhaust pipe 30, and includes an engaging member 41, a plurality of sheet bodies 42, and an adjusting member 43. The engaging member 41 is capable of selectively moving toward or away from the heat exhaust pipe 30, and further includes an adjusting hole 411. The adjusting hole 411 is formed on one surface of the engaging member 41, specifically, on the surface of the engaging member 41 that faces away from the heat exhaust pipe 30. A first screw 4111 is formed on the inner wall surface of the adjusting hole 411.
[0012] As shown in FIGS. 3 and 5 to 7 , the sheets 42 are provided on the other surface of the engaging member 41 opposite the adjustment holes 411. When the engaging member 41 approaches the heat exhaust pipe 30, each sheet 42 can engage with two of the wrinkles 31. Specifically, each sheet 42 has a first side 421 and a second side 422. The first side 421 is connected to the engaging member 41, and the second side 422 is the side of the sheet 42 away from the engaging member 41 and has an arc shape corresponding to the shape of the heat exhaust pipe 30. In this embodiment, the outer periphery of the cross section of the heat exhaust pipe 30 is circular, so the second side 422 has an arc shape. However, in other embodiments, the shape of the second side 422 can be changed depending on the shape of the outer periphery of the cross section of the heat exhaust pipe 30.
[0013] As shown in FIGS. 3 and 5 to 7 , the adjustment member 43 is disposed within the adjustment hole 411 of the engagement member 41 and is adjustable to move the engagement member 41 closer to or further away from the heat exhaust pipe 30. In other words, a user can adjust the distance and engagement degree between the engagement member 41 and the heat exhaust pipe 30 via the adjustment member 43. Specifically, the adjustment member 43 has a second thread 431 formed on its outer circumferential surface and threadedly engaged with the first thread 4111. Note that in this embodiment, the adjustment member 43 is threadedly engaged with the adjustment hole 411, allowing the user to turn the adjustment member 43 to move the engagement member 41 closer to or further away from the heat exhaust pipe 30. However, the manner in which the engagement member 41 moves and the manner in which the adjustment member 43 is connected to the adjustment hole 411 are not limited thereto. In other embodiments, the adjustment member 43 and the adjustment hole 411 may be engaged with each other, and the engagement member 41 may be moved by pushing or pulling the adjustment member 43.
[0014] 3 and 4 to 6, the positioning pipe 50 communicates with the exhaust port 22, one end of the heat exhaust pipe 30 is installed in the positioning pipe 50, and the fixing member 40 is drilled into the positioning pipe 50. In this embodiment, the positioning pipe 50 is tubular, but in other embodiments, it is not limited to this shape.
[0015] As shown in FIGS. 3 and 4 to 6 , the positioning pipe 50 has a pipe portion 51, a stopper portion 52, and a position restricting portion 53. The pipe portion 51 is disposed to surround the heat exhaust pipe 30, and a fixing member 40 is drilled into the pipe portion 51. One end of the stopper portion 52 is connected to the pipe portion 51 and extends in a direction away from the exhaust port 22, and the pipe wall of the heat exhaust pipe 30 is disposed between the pipe portion 51 and the stopper portion 52. Specifically, the pipe wall of the heat exhaust pipe 30 is disposed between the stopper portion 52 and the fixing member 40. When the engaging member 41 approaches the heat exhaust pipe 30 and the sheet body 42 engages with the wrinkles 31 of the heat exhaust pipe 30, the engaging member 41 pushes the heat exhaust pipe 30 to abut against the stopper portion 52. This prevents the engaging member 41 from approaching too close to the heat exhaust pipe 30 and prevents the heat exhaust pipe 30 from being deformed by the engaging member 41 being pushed in. Specifically, if the engaging member 41 pushes the heat exhaust pipe 30 too far, the heat exhaust pipe 30 may be deformed from a cylindrical shape to an elliptical cylindrical shape, etc. Furthermore, one end of the position restricting portion 53 is connected to the pipe body portion 51 and extends in a direction away from the exhaust port 22, and the pipe wall of the heat exhaust pipe 30 is located between the pipe body portion 51 and the position restricting portion 53, thereby allowing the heat exhaust pipe 30 to be positioned on the positioning pipe 50.
[0016] To use this device, first insert one end of the heat exhaust pipe 30 into the positioning pipe 50. Specifically, the pipe wall of the heat exhaust pipe 30 is positioned between the stopper portion 52 and the fixing member 40, and between the pipe body portion 51 and the positioning member 53. Then, the adjusting member 43 is rotated to move the engaging member 41 toward the heat exhaust pipe 30 until the sheet body 42 engages with the creases 31 of the heat exhaust pipe 30, thereby fixing the heat exhaust pipe 30 to the fixing member 40 and the positioning pipe 50. The user can then pull the other end of the heat exhaust pipe 30 out of the heat dissipation hole 11 and stretch it to the appropriate position.
[0017] An advantage of the present invention is that the fixing member 40 is provided. When the fixing member 40 approaches the heat exhaust pipe 30, it engages with the creases 31 of the heat exhaust pipe 30, thereby fixing one end of the heat exhaust pipe 30 to the fixing member 40. As a result, when a user pulls the heat exhaust pipe 30 out of the housing 10, the one end of the heat exhaust pipe 30 is fixed to the fixing member 40, which prevents the entire heat exhaust pipe 30 from being pulled out or becoming displaced due to the user applying excessive force.
