[0005] Preferably, the clamping piece includes two arc hoops, one end of the arc hoop is bent outward in the direction of the arc segment, and the bent part is screwed into the mounting screw, the front end of the mounting screw is screwed into the wall, a plurality of threaded holes are formed on the opposite side of the arc hoop, the threaded holes on one side are one-to-one corresponding, a threaded column one is screwed into one side threaded hole, and a threaded column two is screwed into the other side, a sleeve is commonly sleeved on the threaded column one and the corresponding threaded column two, and a butterfly nut is threaded on the threaded column two.

[0006] Preferably, the length of the threaded column two is greater than that of the threaded column one, and the diameters of the threaded column one and the threaded column two are the same.

[0007] Preferably, the sleeve is plugged with a damping sleeve at both ends, and the damping sleeve is attached to the outer walls of the threaded column one and the threaded column two.

[0008] Compared with the prior art, the utility model has the beneficial effects as follows:

[0009] The smoke pipe structure of the range hood can prevent the smoke pipe from shaking during the smoke exhaust process, avoid affecting the sealing, and shake off the impurities attached to the pipe, thereby improving the hygiene. BRIEF DESCRIPTION OF DRAWINGS

[0014] In the drawing: 1, smoke pipe; 2, fixed mechanism; 21, arc hoop; 22, threaded column one; 23, sleeve; 24, threaded column two; 25, butterfly nut; 26, mounting screw; 27, threaded hole. Specific implementation

[0015] The technical scheme in the embodiments of the utility model will be apparently and completely described below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described implementation regulations only a part of the embodiments of the utility model, but not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor all belong to the range of protection of the utility model.

[0016] Please refer to Figures 1-4 A smoke pipe structure of a range hood, comprising a smoke pipe 1, the smoke pipe 1 is an aluminum foil pipe, the smoke pipe 1 is fixed on the fixed mechanism 2 fixed on the wall, the fixed mechanism 2 includes two clamping pieces that are symmetrical left and right, the two clamping pieces hold the smoke pipe 1 together, the length of the clamping piece is adjustable, and the two ends of the clamping piece along the length adjustment direction are fixed on the wall. The length of the clamping piece can be adjusted to adapt to smoke pipes 1 of different lengths. Since the smoke pipe 1 is relatively soft, if it is not fixed, the suspended part is easy to shake under the action of airflow, which not only affects the sealing performance but also easily shakes off the impurities attached to it, affecting hygiene.

[0017] The clamping piece includes two arc hoops 21, one end of the arc hoop 21 is bent to the outside of the circular arc segment, and the bent part is screwed into the mounting screw 26, the front end of the mounting screw 26 is screwed into the wall, a plurality of threaded holes 27 are formed on the opposite side of the arc hoop 21, and the threaded holes 27 on the two sides correspond one by one, a threaded column one 22 is screwed into one side threaded hole 27, and a threaded column two 24 is screwed into the other side, a sleeve 23 is commonly sleeved on the threaded column one 22 and the corresponding threaded column two 24, and a butterfly nut 25 is threadedly connected to the threaded column two 24.

[0018] The length of the threaded column two 24 is greater than that of the threaded column one 22, the diameters of the threaded column one 22 and the threaded column two 24 are the same, and the threaded column one 22 is used to support one end of the sleeve 23 by being inserted into the sleeve 23, and the length of the threaded column one 22 does not need to be very long.

[0019] The sleeve 23 is plugged with a damping sleeve at both ends, and the damping sleeve is in close contact with the outer wall of the threaded column 1 and the threaded column 2, so that the sleeve 23 will not shake and is not easy to slide up and down when installed between the two threaded columns.
