DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 As shown, a kitchen fume exhaust fan which is easy to disassemble and clean comprises a box body 1, a movable door 2 is arranged on the rear side of the box body 1, two buckle mechanisms 3 are arranged on the rear side of the upper end of the box body 1, the movable door 2 is limited by the two buckle mechanisms 3, a buffer mechanism 4 is arranged on the front side of the movable door 2, the height of the movable door 2 can be adjusted by the buffer mechanism 4, so that the device can adapt to different environments, a smoke outlet pipe 5 is fixedly installed on the upper end of the box body 1, and the smoke extracted when the device is in use will be discharged from the smoke outlet pipe 5.

[0024] Further explanation, in order for the device to extract the fumes in the kitchen, e.g. Figure 2 As shown, two opening grooves 11 are provided at the upper end of the box body 1, and the inner cavities of the two opening grooves 11 are fixedly installed with slide rails 12, and the inner walls of the two slide rails 12 are slidably installed with sliders 13. A smoke inlet hole 14 is provided at the lower end of the box body 1, and a fan body 15 is provided in the inner cavity of the box body 1. When the fan body 15 is started, the oil smoke in the air will be extracted, and the pipe mouth in contact with the smoke inlet hole 14 is the suction end. A smoke baffle 16 is provided on the left side of the fan body 15, and the oil smoke can only be discharged from the device through the smoke outlet pipe 5 through the smoke baffle 16.

[0025] To further explain, in order to block the fan body 15 so that the oil smoke in the device cannot leak, Figure 3 and Figure 4 As shown, the movable door 2 includes a door panel 21, which blocks the fan body 15, so that the oil smoke extracted by the fan body 15 can flow in the box body 1 according to the set pipeline. The door panel 21 is connected to the two sliders 13, so that the door panel 21 is slidably connected to the box body 1. A limiting plate 22 is fixedly installed at the front end of the door panel 21, and the door panel 21 is stopped by the limiting plate 22. Two limit rods 23 are rotatably installed on the upper end of the door panel 21, and a push spring 24 is provided between the two limit rods 23 and the upper end of the door panel 21. The push spring 24 will push the limit rod 23 to rotate so that the limit rod 23 is in a vertical state.

[0026] Further explanation, in order to limit the door panel 21, as shown in FIG. Figure 5 As shown, the snap mechanism 3 includes a fixing plate 31, a pull rod 32 is penetrated through the end surface of the fixing plate 31, and the pull rod 32 is slidably installed on the upper end of the box body 1. A limit block 35 is fixedly installed on the end of the pull rod 32 away from the fixing plate 31. An elastic spring 33 is provided between the limit block 35 and the fixing plate 31. The elastic spring 33 has a force to push the limit block 35, and the end surfaces of the limit block 35 and the limit rod 23 that contact each other are provided with inclined surfaces of the same angle. Pressing the limit rod 23 downward can push the limit block 35 to move, and then the limit block 35 limits the limit rod 23 through the pushing force of the elastic spring 33.

[0027] Further explanation, in order to stop the door panel 21 and buffer it, as shown in FIG. Figure 6 As shown, the buffer mechanism 4 includes a threaded rod 41, and a threaded block 42 is threadedly connected to the surface of the threaded rod 41. The position height of the threaded block 42 can be adjusted by rotating the threaded rod 41. Support plates 43 are fixedly installed at both ends of the threaded block 42. Two buffer springs 44 are fixedly installed in the inner cavities of the two support plates 43. The two buffer springs 44 on the same side are fixedly installed at one end close to each other with a sliding block 45. Baffles 47 are provided on the upper sides of the two support plates 43. The two baffles 47 are rotatably connected to the two sliding blocks 45 on the same side by connecting rods. The threaded block 42 fits tightly against the front end of the door panel 21, and the two sliding blocks 45 on the same side are slidably installed in the inner cavity of the support plate 43 on the same side.

[0028] The specific implementation of this device is as follows: when the device needs to be cleaned, the two pull rods 32 need to be manually pulled in the directions away from each other, and the pull rods 32 will drive the limit blocks 35 to move. During the movement, the limit blocks 35 will squeeze the elastic springs 33 to shrink. After the two limit blocks 35 move a certain distance, the limit rods 23 can no longer be limited, so that the limit rods 23 are pushed by the push springs 24 to rotate to a vertical state. At this time, the door panel 21 will drive the limit plate 22 to move downward under the action of its own gravity. When the limit plate 22 contacts the upper end of the baffle plate 47, the limit plate 22 will push the baffle plate 47 to move downward, so that the baffle plate 47 pushes the sliding blocks 45 on both sides to move in the directions away from each other. When the sliding blocks 45 move, they will squeeze the buffer springs 44 to shrink. The shrink buffer springs 44 will continue to expand and contract, which has a good buffering effect, so that the baffle plate 47 can block the door panel 21 and buffer it at the same time, reduce the noise generated when the device is disassembled, and expose the fan body 15 for easy cleaning.

[0029] By rotating the threaded rod 41, the threaded block 42 and the support plate 43 can be driven to move up and down, so that the device can adjust the height of the door panel 21, so that the device can adapt to different environments, increasing the practicality of the device. After cleaning, the door panel 21 needs to be pulled upward, and then the limit rod 23 is manually pressed to make it contact with the limit block 35. When the inclined surfaces of the two contact each other, the limit rod 23 will push the limit block 35 to move. When the limit rod 23 is pressed to the lower side of the limit block 35, the elastic spring 33 will push the limit block 35 to reset, so that the limit block 35 limits the limit rod 23, and the door panel 21 is fixed in place to complete the installation.

[0030] It should be noted that the specific installation method, circuit connection method and control method of the fan body 15 in the utility model are all conventional designs, and the utility model will not be elaborated in detail.
