Description

Technical Field

[0001] This utility model relates to the field of pipe connection, specifically to a kitchen exhaust pipe device that is easy to install. Background Technology

[0002] The current installation process for kitchen exhaust pipes is often quite complex, requiring professional installers to perform precise measurements and positioning, followed by tedious assembly work, and the sealing performance is relatively poor. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a kitchen exhaust pipe device that is easy to install.

[0004] The technical solution adopted by this utility model is as follows:

[0005] An easy-to-install kitchen exhaust pipe device includes a bottom end of an exhaust pipe fixedly connected to the top of a range hood. The top of the exhaust pipe has a smoke exhaust pipe, and a connecting pipe is provided between the bottom end of the smoke exhaust pipe and the top end of the exhaust pipe. The inner walls of both ends of the connecting pipe abut against the outer walls of the top end of the exhaust pipe and the outer walls of the bottom end of the smoke exhaust pipe, respectively. Both ends of the inner wall of the connecting pipe are fixedly connected to U-shaped retaining rings. The two U-shaped retaining rings are slidably inserted into the inner walls of the exhaust pipe and the smoke exhaust pipe, respectively. The connection pipe and the U-shaped retaining rings are respectively the exhaust pipe and the smoke exhaust pipe. Both ends of the connecting pipe are fixedly connected to soft pads. The two soft pads are respectively fitted onto the outer walls of the exhaust pipe and the smoke exhaust pipe. The outer walls of the two soft pads are fitted with clamps, which clamp the soft pads at both ends through the exhaust pipe and the smoke exhaust pipe.

[0006] The beneficial effects of this utility model are:

[0007] This invention utilizes a combination of connecting pipes, U-shaped retaining rings, soft pads, and clamps to quickly complete the installation and connection of exhaust pipes, greatly simplifying the installation process and improving work efficiency.

[0008] Because of the detachable connection method, the clamps, pads and connecting pipes can be easily removed when maintenance or replacement of the exhaust pipe is required, thus facilitating maintenance or replacement work.

[0009] The use of U-shaped baffles and soft pads effectively improves the airtightness between exhaust pipes, preventing gas leakage. This not only improves the exhaust efficiency of the range hood but also reduces oil fumes and odors in the kitchen. Attached Figure Description

[0015] like Figure 1-4 As shown: A kitchen exhaust pipe device that is easy to install includes a range hood 1. The top of the range hood 1 is fixedly connected to the bottom end of the exhaust pipe 2. The top of the exhaust pipe 2 has a smoke exhaust pipe 3. The bottom end of the smoke exhaust pipe 3 and the top end of the exhaust pipe 2 are connected to a connecting pipe 4. The inner walls of both ends of the connecting pipe 4 abut against the outer wall of the top end of the exhaust pipe 2 and the outer wall of the bottom end of the smoke exhaust pipe 3, respectively. Both ends of the inner wall of the connecting pipe 4 are fixedly connected to U-shaped retaining rings 5. The two U-shaped retaining rings 5 ​​are slidably inserted into the inner walls of the exhaust pipe 2 and the smoke exhaust pipe 3, respectively. The connecting pipe 4 and the U-shaped retaining rings 5 ​​are respectively the exhaust pipe 2 and the smoke exhaust pipe 3. Both ends of the connecting pipe 4 are fixedly connected to soft pads 6. The two soft pads 6 are respectively sleeved on the outer walls of the exhaust pipe 2 and the smoke exhaust pipe 3. The outer walls of the two soft pads 6 are each fitted with a clamp 7. The clamp 7 clamps the soft pads 6 at both ends through the exhaust pipe 2 and the smoke exhaust pipe 3.

[0016] First, ensure that the range hood 1 has been correctly installed and fixed, and that the top of the range hood 1 and the bottom of the exhaust pipe 2 have been fixedly connected to form a whole.

[0017] Next, the exhaust pipe 3 needs to be connected to the gas outlet pipe 2. At this time, the connecting pipe 4 is used as an intermediary, with its two ends abutting the top of the gas outlet pipe 2 and the bottom of the exhaust pipe 3, respectively.

[0018] Both ends of the inner wall of the connecting pipe 4 are fixed with U-shaped retaining rings 5. During the insertion process, these two U-shaped retaining rings 5 ​​will slide into the inner side of the gas outlet pipe 2 and the smoke exhaust pipe 3 respectively. This step ensures that the relative position between the connecting pipe 4 and the gas outlet pipe 2 and the smoke exhaust pipe 3 is stable and prevents gas leakage.

[0019] To further enhance the airtightness and stability of the connection, soft pads 6 are fixed at both ends of the connecting pipe 4. These two soft pads 6 are respectively fitted onto the outer walls of the air outlet pipe 2 and the smoke exhaust pipe 3, serving as a buffer and sealing function.

[0020] Finally, clamp the soft pad 6 with the clamp 7. The clamping force of the clamp 7 makes the soft pad 6 fit more tightly against the outer wall of the exhaust pipe 2 and the smoke pipe 3, thereby ensuring the airtightness and stability of the entire exhaust pipe device.
