Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary equipment technology, specifically, it relates to an air conditioning exhaust pipe. Background Technology

[0002] Gas-fired air conditioners produce combustion fumes during actual use, which need to be exhausted. The exhaust pipe needs to pass through the wall to expel the fumes outdoors.

[0003] Currently, the exhaust pipe is located outdoors, and to prevent birds from entering the pipe, a filter screen is usually installed to block them. However, the filter screen is fixed at the end of the exhaust pipe, making maintenance and cleaning inconvenient. Secondly, the main and tail pipes of the exhaust pipe are arranged in a right-angled inverted L-shape, which makes it easy for rainwater and dirt to fall into the gas air conditioner's operating room.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: An air conditioning exhaust pipe includes a main exhaust pipe, a transition pipe, an exhaust tail pipe, a stainless steel filter screen, a pull rod, a sealing end cap, and an anti-backflow baffle. The transition pipe is in the shape of an inverted U, with one end connected to the end of the main exhaust pipe and the other end connected to one end of the exhaust tail pipe. The anti-backflow baffle is installed inside the exhaust tailpipe, and the stainless steel filter screen is movably installed inside the cavity of the exhaust tailpipe. The middle part of the stainless steel filter screen is fixedly connected to one end of the pull rod.

[0006] In a preferred embodiment of this utility model, the other end of the exhaust pipe is threaded with the sealing end cap, and the end of the pull rod away from the stainless steel filter screen moves and seals through the middle of the sealing end cap.

[0007] In a preferred embodiment of this utility model, a rubber ring is fitted around the edge of the stainless steel filter screen, and the rubber ring fits snugly against the inner wall of the exhaust pipe.

[0008] In a preferred embodiment of this utility model, the transition pipe is connected to the main exhaust pipe and the exhaust tail pipe in a detachable manner.

[0009] In a preferred embodiment of this utility model, a sealing ring is provided at the penetration point between the sealing end cap and the pull rod.

[0010] Compared with the prior art, the present invention has the following advantages: This utility model's inverted U-shaped transition pipe prevents dirt from falling into the main exhaust pipe during cleaning, while also preventing external rainwater from flowing back into the room, solving the backflow problem of traditional right-angle structures. The stainless steel filter screen is a pull-out structure; after removing the sealed end cap, the filter screen can be removed for cleaning by pulling the lever, solving the problem of inconvenient maintenance of traditional fixed filter screens. The rubber ring on the edge of the stainless steel filter screen not only enhances bird protection and dirt-blocking fit, but also wipes the inner wall of the exhaust pipe while being pulled out, simultaneously cleaning the pipe cavity.

[0011] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0015] like Figures 1 to 3 As shown, an air conditioner exhaust pipe has a transition pipe 2 in the shape of an inverted U. Its lower end is welded to the top of the exhaust main pipe 5 and its upper end is welded to the inner end of the exhaust tail pipe 1. The exhaust tailpipe 1 runs horizontally through the wall, with its outer end extending outside the wall and its inner end connected to the transition pipe 2; An anti-backflow baffle 6 is fixedly installed inside the exhaust tailpipe 1 near the transition pipe 2; a stainless steel filter screen 7 is movably placed inside the exhaust tailpipe 1, with its middle part welded to the inner end of the pull rod 3, and its edge fitted with a rubber ring 8 that fits the pipe cavity; The outer end of the exhaust tailpipe 1 is threaded and sealed with end cap 4. The outer end of the pull rod 3 is sealed through the end cap 4 and a sealing ring is provided at the point of penetration to ensure the airtightness of the exhaust.

[0016] Smoke exhaust process: The flue gas from the gas air conditioner is discharged outdoors sequentially through the main exhaust pipe 5 → transition pipe 2 → exhaust tail pipe 1. The inverted U-shaped transition pipe and the anti-backflow baffle 6 work together to prevent rainwater and dirt from flowing back in. Cleaning process: Unscrew the sealing end cap 4, pull the lever 3 outwards to move the stainless steel filter screen 7 along the tube cavity, and simultaneously wipe the inner wall with the rubber ring 8. After cleaning the filter screen, reset it and tighten the sealing end cap 4.

[0017] The implementation principle of an air conditioning exhaust pipe in this embodiment is as follows: In this technical solution, the exhaust main pipe 5 and the exhaust tail pipe 1 are connected by a transition pipe 2. The transition pipe 2 is in an inverted U-shape, which ensures that when the inner cavity of the exhaust tail pipe 1 is cleaned later, some dirt will not fall into the exhaust main pipe 1 under the action of gravity, and also avoids the situation where external rainwater flows back into the inner cavity of the exhaust main pipe 5. Because a removable stainless steel filter screen 7 is installed inside the exhaust tailpipe 5, the middle part of the stainless steel filter screen 7 is connected to the end of the pull rod 3. The pull rod 3 is movable and sealed through the middle of the sealing end cover 4. The sealing end cover 4 is screwed onto the end of the exhaust tailpipe 5. When it is necessary to clean the exhaust tailpipe 5, the sealing end cover 4 is removed, and then the pull rod 3 is pulled outward to drive the stainless steel filter screen 7 and the rubber ring 8 on the stainless steel filter screen 7 to clean the inner cavity of the exhaust tailpipe 1, which is convenient and quick.

[0018] The anti-backflow baffle 6 installed at the bottom of the inner cavity of the outer port of the exhaust tailpipe 1 can prevent external rainwater from entering the inner cavity of the exhaust tailpipe 1.
