[0001] The utility model belongs to the field of oil fume purification integrated machines, and particularly relates to an oil filter with an adjustable air inlet. Background Art

[0002] An all-in-one oil fume purification machine is a device that integrates oil fume collection and purification. Oil fume purification refers to the process of collecting, filtering and purifying oil fumes generated during the cooking process. It is widely used in catering, industrial kitchens and other places. Unlike ordinary household range hoods, an all-in-one oil fume purification machine is a large-scale commercial equipment that purifies oil fumes in the process of absorbing oil fumes, aiming to control oil fume emissions and improve air quality. An all-in-one oil fume purification machine usually adopts a combination of multiple purification technologies to achieve the purpose of efficient purification.

[0003] Generally, there are multiple stoves installed under the oil fume purification machine. During the cooking process, users only use some of the stoves most of the time, and rarely use multiple stoves at the same time. What is extracted from the unused stoves is not oil fumes, but fresh air. In this way, the oil fume purification machine can only run at full load for a long time, and the extraction effect is not good, which wastes resources.

A plurality of accommodating channels of adjustable size are formed between the first and second adjustment parts, and the accommodating channels are used to pass oil smoke. The toggle plate is mounted on the second adjustment part and is used to toggle the second adjustment part to rotate relative to the central axis of the rotation hole. The plurality of second adjustment parts are in transmission connection with each other, and the toggle plate is rotated to drive the plurality of second adjustment parts to rotate relative to the first adjustment part, thereby adjusting the size of the accommodating channels.

[0010] Furthermore, the first adjusting portion includes: a fixed mesh bar and two fixed mesh bar edges. The two fixed mesh bar edges are vertically mounted on the fixed mesh bar, and the two fixed mesh bar edges are respectively arranged at two ends of the fixed mesh bar.

[0011] Furthermore, the second adjustment portion includes: a moving mesh bar, two moving mesh bar edges, two moving mesh bar edges, and a gear plate.

[0029] Example:

[0030] Please refer to Figures 1 to 7 As shown, this embodiment provides an oil filter with an adjustable air inlet 30, comprising: an oil filter frame 10, an adjustment assembly, and a toggle plate 201. The inner wall of the oil filter frame 10 is provided with a mounting groove 101, and the bottom of the mounting groove 101 is provided with a plurality of rotation holes 102; the adjustment assembly is divided into a plurality of first adjustment parts and a plurality of second adjustment parts, the first adjustment part being fixedly mounted in the mounting groove 101, and the second adjustment part being rotatably mounted in the rotation hole 102, and a plurality of accommodating channels 200 of adjustable size being formed between the first adjustment part and the second adjustment part, and the accommodating channels 200 are used to pass oil smoke; the toggle plate 201 is mounted on the second adjustment part, and is used to toggle the second adjustment part to rotate relative to the central axis of the rotation hole 102, and the plurality of second adjustment parts are connected to each other in a transmission manner, and the toggle plate 201 is rotated to drive the plurality of second adjustment parts to rotate relative to the first adjustment part, thereby adjusting the size of the accommodating channels 200.

[0031] In this embodiment, if Figure 1 、 Figure 2 and Figure 4As shown, the oil filter frame 10 uses a universal mounting frame for common oil fume purification all-in-one machines. First, prepare the oil filter frame 10, adjustment assembly, and toggle plate 201. A mounting slot 101 is defined on the inner wall of the oil filter frame 10, and multiple rotation holes 102 are precisely defined at the bottom of the mounting slot 101. Ensure that the rotation holes 102 are accurately positioned and sized to facilitate subsequent installation of the adjustment assembly. The first adjustment portion of the adjustment assembly is fixedly mounted within the mounting slot 101. Welding, bolting, or other methods can be used to ensure its securement. After the first adjustment portion is installed, the second adjustment portion is installed one by one into the rotation hole 102, ensuring that the installed second adjustment portion can rotate smoothly around the central axis of the rotation hole 102. During installation, ensure that the initial position between the first and second adjustment portions forms a sized accommodating channel 200 to facilitate the passage of oil fumes. Next, install the toggle plate 201 onto one of the second adjustment portions. This can be done by connecting with a slot or securing with screws. After installation, the multiple second adjustment parts are interconnected via a transmission mechanism, such as a chain or gears. In actual use, when the size of the accommodating channel 200 needs to be adjusted, the toggle plate 201 can be manually rotated. Rotation of the toggle plate 201 causes the connected second adjustment parts to rotate about the central axis of the rotating hole 102. Because the multiple second adjustment parts are interconnected, rotation of one second adjustment part causes all other second adjustment parts to rotate synchronously. As the second adjustment parts rotate, the size of the accommodating channel 200 formed between the first and second adjustment parts changes. To increase the size of the air inlet 30, the toggle plate 201 is rotated in a specific direction, increasing the size of the accommodating channel 200. To decrease the size of the air inlet 30, the toggle plate 201 is rotated in the opposite direction, causing the second adjustment parts to rotate in the opposite direction, reducing the size of the accommodating channel 200. This allows the oil filter of the air inlet 30 to be adjusted, meeting the requirements for oil fume filtration intake in different situations.

[0032] Furthermore, in some implementations of this embodiment, Figure 4 、 Figure 5 、 Figure 6 As shown, the first adjusting portion includes: a fixed mesh bar 211 and two fixed mesh bar edges 212. The two fixed mesh bar edges 212 are vertically mounted on the fixed mesh bar 211, and the two fixed mesh bar edges 212 are respectively arranged at both ends of the fixed mesh bar 211.

[0033] In this embodiment, the fixed mesh bar 211 has a bottom surface, which is fixed on the inner wall of the oil filter mesh frame 10. The fixed mesh bar 211 is a sheet metal processing part with a symmetrical design. The fixed mesh bar 211 is divided into two parts. The two parts are relatively arranged on two opposite sides of the oil filter mesh frame 10. The multiple fixed mesh bars 211 in each part are evenly spaced apart. Fixed mesh bar edges 212 are provided on both sides of the fixed mesh bar 211 to guide the formation of the accommodating channel 200.

[0034] Furthermore, in some implementations of this embodiment, Figures 1 to 7 As shown, the second adjustment unit includes a moving mesh bar 221, two moving mesh bar edges 222, two moving mesh bar edges 222, and a gear plate 224. The two moving mesh bar edges 222 are mounted perpendicularly to the moving mesh bar 221 and are respectively located at both ends of the moving mesh bar 221; pins 223 are fixed at both ends of the rotation center of the moving mesh bar 221; and the gear plate 224 is mounted on the moving mesh bar 221. The gear plates 224 on the multiple moving mesh bars 221 mesh with each other. Rotating the toggle plate 201 drives the multiple moving mesh bars 221 to rotate, thereby adjusting the size of the accommodating channel 200.

[0035] In this embodiment, if Figures 3 to 7 As shown, the moving mesh bar 221 is made of sheet metal processing material and is designed to be axially symmetrical. By rotating the installation angle of the moving mesh bar 221, the setting gap between the moving mesh bar 221 and the fixed mesh bar 211 is changed, thereby changing the size of the accommodating channel 200.

[0036] Furthermore, in some implementations of this embodiment, Figures 1 to 6 As shown, the multiple moving mesh strips 221 and the multiple fixed mesh strips 211 are arranged in an interlaced manner.

[0037] In this embodiment, if Figure 5 As shown, the movable mesh strips 221 are interspersed and arranged at intervals in the gaps between the two parts of the fixed mesh strips 211, and respectively contact the two parts of the fixed mesh strips 211, thereby forming a reliable seal.

[0038] Furthermore, in some implementations of this embodiment, Figures 1 to 6 The toggle plate 201 is fixedly arranged on the middle moving mesh bar 221, and the toggle plate 201 is rotated to rotate the moving mesh bar 221, thereby driving the moving mesh bar edges 222 to move toward the fixed mesh bar edges 212 on both sides.

[0039] To sum up, when using an oil filter with an adjustable air inlet 30, the movable mesh strips 221 are rotated by toggling the toggle plate 201, so that the movable mesh strip edges 222 and the fixed mesh strip edges 212 can be closed or separated, closing or opening the smoke inlet of the oil filter. The combination of multiple fixed mesh strips 211 and multiple second adjustment parts drives the multiple second adjustment parts and multiple fixed mesh strips 211 to cooperate with each other under the action of the mutual engagement of the gear plate 224, thereby achieving the purpose of adjusting the smoke extraction effect of the oil fume purification machine.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
