Technical Field
[0001] The utility model relates to the technical field of kitchen ventilation, and in particular to a kitchen ventilation device which is easy to install. Background Art
[0002] The main functions of kitchen ventilation are as follows: First, a large amount of oil smoke and water vapor will be generated during the cooking process in the kitchen. These substances will have an impact on human health, such as causing respiratory diseases and decreased vision. A good ventilation and exhaust system can effectively reduce the harm of these harmful substances to the health of employees; second, oil smoke is a flammable substance. If it accumulates too much, it is easy to cause a fire once it encounters a fire source. Installing and using a suitable ventilation and exhaust system can eliminate this safety hazard.
[0003] After searching, the announcement number CN216557527U discloses a kitchen ventilation device, which belongs to the technical field of kitchen ventilation, including a window frame, a glass window is arranged in the window frame, and a body is also connected to the window frame, and two cavities are separated by a partition in the body, one end of the cavity is open, and the other end is provided with an air inlet, a fan blade is rotatably connected in the cavity, and an operating cavity is arranged on both sides adjacent to the opening end of the cavity, a rotating plate is rotatably connected in the operating cavity, and the rotating plate is connected to the open end of the cavity through a movable part, and an accommodating cavity is arranged on one side of the operating cavity, and a motor is fixedly connected in the accommodating cavity, and the main shaft of the fan blade passes through the side wall of the cavity and extends into the accommodating cavity, and is connected to the output end of the motor, which solves the problem that directly opening the window for ventilation in the kitchen may easily cause the flame in the gas stove to swing or go out, affecting cooking.

At this time, the two groups of second conical teeth meshing on the upper and lower sides of the first conical teeth rotate synchronously and drive the threaded rod to rotate. At this time, the lifting slide threadedly connected to the outside of the threaded rod moves synchronously with the rotation of the threaded rod until the installation pressure block on one side of the lifting slide is disengaged from the pin groove and the pin groove in turn. At this time, the staff can quickly remove the filter plate from the inside of the ventilation bin and clean it.

[0027] See also Figure 3 , filter grooves 211 are evenly spaced in the middle of the filter plate 21, and the upper and lower sides of the filter plate 21 are attached to the inner wall of the ventilation bin 1. Slots 22 are symmetrically penetrated through the upper and lower sides of the filter plate 21, and pin grooves 12 are opened at the upper and lower positions of the inner wall of the ventilation bin 1 corresponding to the slots 22. The sizes of the pin grooves 12 and the slots 22 match each other. This design can facilitate the installation of the pressing block 62 to move and pass through the above two to complete the fixed installation of the filter plate 21 on the inner side of the ventilation bin 1, thereby avoiding the loosening of the filter plate 21 after installation.
[0028] See also Figure 6 A bearing 33 is provided at the place where the screw rod 31 is in contact with the inner wall of the ventilation bin 1, the inner ring of the bearing 33 is fixedly connected to the outer surface of the screw rod 31, the outer ring of the bearing 33 is fixedly connected to the inner wall of the ventilation bin 1, and a screw disk 32 is fixedly connected to the middle of the outer surface of the screw rod 31, and an anti-slip sleeve 321 is distributed on the outer surface of the screw disk 32. By providing a bearing 33 at the connection between the screw rod 31 and the ventilation bin 1, the screw rod 31 can rotate more smoothly. At the same time, an anti-slip sleeve 321 is provided on the outer side of the screw disk 32 to increase the friction of the staff's grip and avoid slipping during rotation.
[0029] See also Figure 5 - Figure 7 The threaded rod 51 is composed of two groups, which are arranged in the inner track groove of the inner seat 11 from top to bottom.
