A hood flue gas pipeline includes a pulling pipe (1) and a folding pipe (2), a chuck edge (101) fitted in a wall of the pulling pipe (1), and a double-sided tape on a surface close to the wall of the chuck edge (101). 102 is attached, one end of the pipe 2 to be folded is provided with a chuck portion 201, and the other end has an edge 202 to be connected. The diameter of the chuck portion 201 is larger than the inner diameter of the drawing pipe 1, and the diameter of the connecting edge 202 is smaller than the inner diameter of the drawing pipe 1. The pipe 2 to be folded is attached to the pipe 1 to be pulled, the connecting edge 202 is located on the inner side of the wall, and the chuck part 201 is located on the outer side of the wall. The steel mesh cover 4 is put on the surface of the pulling pipe 1 that comes into contact with the chuck portion 201 and the right end surface of the pulling pipe 1. [Selection] Figure 1

Description

  This new utility model refers to a hood flue gas pipeline.

  The hood is a common kitchen facility, and when exhausting smoke, use a smoke exhaust pipeline. With the existing technology, the structure of the flue gas pipeline is a single, simple foldable pipe, the material of this pipe is flexible, and it will deform well if it is subjected to pressure during the installation process, the hole drilled in the wall If the oil fume enters the wall through the broken mouth, it is difficult to detect after damage, and the wall surface becomes black and the entire wall turns yellow. If this is not beautiful and the smoke vent is too small, the installation of this kind of smoke pipeline is unlikely to be successful.

  The necessary problem to be solved by this new type of utility provides a kind of hood flue gas pipeline. This measure has a high structural strength to avoid breakage, and this measure is highly sealed to the wall to block back into the chamber of the oil fume, and at the same time, this measure prevents rainwater backflow. Avoid well.

  In order to solve the above problems, the new model takes the following technical measures: the hood flue gas pipeline, including the pulling pipe and the folding pipe, the upper chuck edge of one end fitted in the wall of the pulling pipe There is a double-sided tape on the surface near the wall of the chuck edge, one end of the folding pipe has a chuck part, the other end has an edge to tie, and the diameter of the chuck part is pulled The inner diameter of the pipe is larger than the inner diameter of the pulling pipe, the folding pipe is installed in the pulling pipe, the connecting edge is located on the inner side of the wall, and the chuck part is located on the outer side of the wall, A steel mesh cover is put on the surface of the pulling pipe that comes into contact with the chuck portion and the right end surface of the pulling pipe.

  As an excellent technical measure, the folding and pulling pipes are all PVC plastic pipes, the folding pipes are PVC soft hoses, and the pulling pipes are PVC hard hoses.

  As an excellent technical measure, there is a semicircular shutter cover at the tip of the part located outside the wall of the pulling pipe, and it is fixed by attaching the shutter cover and the pulling pipe.

  As an excellent technical measure, there are three or more knot holes that connect to the hood smoke exhauster in the annular installation of the tying edges.

  The beneficial effects of this measure are: to avoid breakage, this measure has a high structural strength, and to prevent it from being pulled back into the oil fume chamber, this measure is highly sealed between the walls, This measure avoids the backflow of rainwater well and is easy and convenient to install, the structure of this measure is simple, the cost is low, and it is suitable for popularization.

This is a sketch of the structure of this new type.

  In order to make it easier for engineers in the technical field to understand the merits and features of this utility model, and to further clearly define the scope of protection of this utility model, we will now explain in detail the excellent examples of this utility model together with the accompanying drawings. To do.

  According to FIG. 1, the hood flue gas pipeline has an upper chuck edge 101 fitted into the wall 3 of the pulling pipe 1, including the pulling pipe 1 and the folding pipe 2, and is close to the wall of the chucking edge 101. Double-sided tape 102 is attached to the surface of the side, one end of the folding pipe 2 is provided with a chuck part 201, and the other end has an edge 202 to be connected. The diameter of the chuck part 201 is larger than the inner diameter of the pipe 1 to be drawn. The diameter of the connecting edge 202 which is larger is smaller than the inner diameter of the pulling pipe 1, the folding pipe 2 is mounted in the pulling pipe 1, the connecting edge 202 is located on the inner side of the wall 3, and the chuck part 201 is outside the wall 3 The steel mesh cover 4 is put on the surface of the pulling pipe 1 that is in contact with the chuck 201 and the right end surface of the pulling pipe 1.

  An excellent example of this practical new model, the folding pipe 2 and the pulling pipe 1 are all PVC plastic pipes, the folding pipe is a PVC soft hose, and the pulling pipe is a PVC hard hose.

  In an excellent example of this practical new type, there is a semicircular shutter cover 5 at the tip of the portion located outside the wall 3 of the pulling pipe 1, and the shutter cover 5 and the pulling pipe 1 are glued and fixed.

  In an excellent example of this practical new model, there are three or more tie holes that can be connected to the hood smoke exhauster in the annular installation of the linking edge 202. (No floor plan)

  The beneficial effects of this measure are: to avoid breakage, this measure has a high structural strength, and to prevent it from being pulled back into the oil fume chamber, this measure is highly sealed between the walls, This measure avoids the backflow of rainwater well and is easy and convenient to install, the structure of this measure is simple, the cost is low, and it is suitable for popularization.

  The above is only a practical implementation method of the new utility model, but the scope of protection of the new utility model is not limited to this, and unless it is labor with all creativity, the change and replacement that can be imagined are all Should belong within the scope of protection. Therefore, the protection scope of this new utility model should be based on the protection scope defined by the rights request.
