[0040] Example:
[0041] See Figures 2 to 10A convenient and easy-to-clean fumigation machine fumigation hood includes a fumigation hood body 1.
[0042] See Figure 6 The bottom of the smoking hood body 1 is provided with a first inclined surface 11 and a second inclined surface 12 that are set opposite to each other. The first inclined surface 11 is provided with a smoking port 13, and the top of the smoking hood body 1 is provided with a smoke outlet 14.
[0043] See Figure 7 and Figure 8 A baffle 5 is provided on the second inclined surface 12, and the upper end of the baffle 5 is hinged to the side wall of the fumigation hood body 1 via a hinge 53. The bottom of the baffle 5 has a first folded edge 51 bent upwards, and the fumigation opening 13 is provided above the first folded edge 51. See also... Figure 5 and Figure 6 The upper end of the first fold 51 is bent into the inner cavity of the smoking hood body 1 to form a second fold 52.
[0044] See Figure 7 and Figure 8 The baffle 5 is connected to the smoke hood body 1 via a locking structure. The locking structure includes a buckle 7 and a hook 6. The hook 6 is welded and fixed to the outer side of the baffle 5, and the buckle 7 is installed on the smoke hood body 1, with the buckle 7 engaging with the hook 6.
[0045] See Figure 9 and Figure 10 The hook and loop 7 is a common product on the market and can be purchased directly. To clearly explain its working principle, this embodiment provides a specific structure of a common hook and loop 7:
[0046] See Figure 8 , Figure 9 and Figure 10 The latch 7 includes a base plate 71, a pin 72, a closing plate 73, a torsion spring 74, a seat 75, a padlock 76, and a buckle 77. The base plate 71 is welded and fixed to the side wall of the fumigation hood body 1. One end of the base plate 71 is rotatably connected to the closing plate 73 via the pin 72. A torsion spring 74 is fitted onto the pin 72. One end of the torsion spring 74 abuts against the top surface of the base plate 71, and the other end abuts against the bottom surface of the closing plate 73. The function of the torsion spring 74 is to spring the closing plate 73 away from the base plate 71. A seat 75 is provided at the end of the base plate 71 away from the pin 72. The seat 75 is an integral structure with the base plate 71 and is used to engage with the padlock 76. The closing plate 73 has an insertion hole 731 for insertion into the seat 75. A buckle 77 is also rotatably connected to the closing plate 73 for engaging with the hook 6.
[0047] The working principle of this embodiment is as follows:
[0048] When it is necessary to clean the inner cavity of the smoking hood body 1: First, the staff opens the locking mechanism; then, the staff opens the baffle 5, so that the inner cavity of the smoking hood body 1 can be opened; then, the staff cleans the inner cavity of the smoking hood body 1; next, the staff closes the baffle 5 and uses the locking mechanism again to lock the baffle 5 and the smoking hood body 1 together.
[0049] When opening the locking mechanism, the operation is as follows: First, the operator uses a key to open the padlock 76, detaching the padlock 76 from the seat 75, so that the opening and closing plate 73 can be opened by the torsion spring 74. When the opening and closing plate 73 is opened, the insertion hole 731 on the opening and closing plate 73 separates from the seat 75. Then, the operator pries the opening and closing plate 73 outward, causing the locking plate 73 to move the buckle 77 closer to the hook 6, so that the buckle 77 has enough space to leave the hook 6. Finally, the operator pulls the buckle 77 away from the hook 6, thus completing the operation of opening the locking mechanism.
[0050] When using the locking mechanism to lock the baffle 5 and the smoking hood body 1, the operation is as follows: First, the operator hangs the buckle 77 on the hook 6; then, the operator overcomes the elastic force of the torsion spring 74 and reverses the opening and closing plate 73, so that the insertion hole 731 on the opening and closing plate 73 is inserted into the hole seat 75; finally, the operator hangs the padlock 76 on the hole seat 75 and locks the padlock 76, thus completing the locking operation.
[0051] Based on the working principle described above, this embodiment has the following advantages:
[0052] First, in this embodiment, by providing an openable baffle 5 at the bottom of the smoking hood body 1, the baffle 5 can be opened when cleaning the inner cavity of the smoking hood body 1, so that the inner cavity of the smoking hood body 1 is open, making it convenient for staff to clean the oil stains on the inner cavity of the smoking hood body 1.
[0053] Second, by bending the bottom of the baffle 5 upward to form a first folded edge 51, the first folded edge 51 can prevent oil stains on the inner wall of the baffle 5 from sliding down from the bottom of the baffle 5, thereby improving the oil stain containment effect.
[0054] Secondly, by bending the upper end of the first fold 51 into the interior of the fumigation hood body 1 to form the second fold 52, the risk of the upper end of the first fold 51 scratching the staff can be reduced, which is beneficial to improving the safety of use.
[0055] Fourth, in the locking structure provided in this embodiment, the cooperation between the buckle 7 and the hook 6 facilitates the opening and closing of the baffle 5, thereby making the smoke hood structure of this embodiment simpler and more reliable.
[0056] In addition, see Figure 7 and Figure 8A guide plate 8 is fixedly installed at the top of the smoke outlet 14. The guide plate 8 is inclined downwards, and the smoke inlet 13 is located below the guide plate 8, so that the smoke inlet 13 is located between the guide plate 8 and the first folded edge 51. By setting the guide plate 8, the oil fumes emitted by the extruder body 4 can be guided to flow through the area below the guide plate 8 and enter the smoke inlet 13, which helps to improve the smoke extraction effect.
[0057] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
