[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figure 1-4 The present invention provides the following technical solution:

[0035] A gas flow controller, comprising:

[0036] Outer shell 1;

[0037] Rotating hole 2 is located at the upper end of outer casing 1;

[0038] Rotating rod 3 is rotatably connected to rotating hole 2;

[0039] Limiting block 4 is fixedly connected to the circumferential surface of rotating rod 3;

[0040] Gear 5 is fixedly connected to the circumferential surface of rotating rod 3;

[0041] Handle 6 is fixedly connected to the upper end of the rotating rod 3;

[0042] T-slot 7, T-slot 7 is formed on the inner circumference of the outer shell 1;

[0043] T-shaped tooth block 8 is slidably connected in T-shaped groove 7, and T-shaped tooth block 8 meshes with gear 5;

[0044] Sealing block 9 is fixedly connected to one side of T-shaped toothed block 8;

[0045] Gas pipe 10 is fixedly connected to one side of the outer casing 1;

[0046] A filtration mechanism is installed inside the gas pipeline 10 to filter the gas passing through the gas pipeline 10.

[0047] In a specific embodiment of this utility model, the outer shell 1 serves as the protective and supporting structure for the entire device. The rotating hole 2 accommodates the rotating rod 3, allowing it to rotate freely. The rotating rod 3 and handle 6 are connected at one end and have a gear 5 at the other end. By operating the handle 6, the rotation of the rotating rod 3 can be controlled. Two limiting blocks 4 are provided to prevent the rotating rod 3 from dislodging from the rotating hole 2 and to maintain the stability of the rotating rod 3's position. The gear 5 is used to transmit power to the T-shaped toothed block 8. The T-shaped groove 7 provides a sliding path for the T-shaped toothed block 8. The sealing block 9 is used to seal or release gas. The T-shaped toothed block 8 meshes with the gear 5. When the rotating rod 3 rotates, the T-shaped toothed block 8 drives the sealing block 9 to slide along the T-shaped groove 7 to adjust the opening and closing degree of the gas channel, thereby controlling the gas flow rate. The gas pipe 10 serves as the channel for gas in and out. A filter mechanism is set inside the gas pipe 10 to filter out impurities and moisture from the gas passing through the gas pipe 10.

[0048] Please refer to the details. Figure 1-4 The filtration mechanism includes a filter base 11, multiple filter cotton rods 12, a filter screen 14, and a retainer 13. The filter base 11 is fixedly connected to the inner circumference of the gas pipeline 10, the filter cotton rods 12 are connected to one side of the filter base 11, the filter screen 14 is slidably connected to the inner circumference of the gas pipeline 10, and the retainer 13 is fixedly connected to one side of the filter screen 14.

[0049] In this embodiment: the filter base 11 has holes at the bottom for gas to pass through, providing a stable foundation support for the entire filtration system; the filter screen 14 is used to remove large impurities; the filter swabs 12 are made of highly efficient adsorption material, which can effectively capture and filter small particles and moisture in the gas, further filtering the gas; and the retainer 13 is used to stably hold the filter screen 14 in its working position and facilitate disassembly and maintenance.

[0050] Please refer to the details. Figure 1-4 The frame of the filter screen 14 is made of magnetic material, and the filter cotton swab 12 is locked inside the card sleeve 13.

[0051] In this embodiment: the frame of the filter screen 14 is made of magnetic material, which can fix the filter screen 14 in the gas pipeline 10 and remove it, making it convenient for personnel to maintain. The filter cotton rod 12 is locked in the sleeve 13, so that personnel can pull out the filter screen 14 and then take out the filter cotton rod 12 to clean it, which improves the maintenance efficiency of personnel.

[0052] Please refer to the details. Figure 1-4 A connecting block 15 is fixedly connected to the circumferential surface of the gas pipeline 10, and the inner circumferential wall of the connecting block 15 is provided with threads.

[0053] In this embodiment, the connecting block 15 achieves seamless integration with other systems via a threaded connection. This allows the gas flow controller to be easily integrated into more complex gas handling or transmission systems, making it suitable for various industrial applications.

[0054] Please refer to the details. Figure 1-4 A pressure gauge 16 is fixedly connected to the circumferential surface of the outer casing 1.

[0055] In this embodiment, the pressure gauge 16 can display the gas pressure in the gas pipeline 10 in real time, helping users to accurately grasp the current operating status of the system. The pressure gauge 16 is existing technology and will not be described in detail here.

[0056] Please refer to the details. Figure 1-4 The filter cotton swab 12 is hollow, and the gas pipe 10 is made of iron.

[0057] In this embodiment, the filter cotton rod 12 is hollow, which increases the gas flow area and reduces the pressure loss when the gas passes through, while maintaining a high efficiency in capturing particulate matter. The gas pipe 10 is made of iron, which can cooperate with the magnetism of the filter screen 14 to fix and remove the filter screen 14 without too many complicated operations.

[0058] The working principle and usage process of this utility model are as follows: By rotating the handle 6, the user drives the rotating rod 3 and its gear 5 to rotate. The gear 5 meshes with the T-shaped tooth block 8. When the rotating rod 3 rotates, the T-shaped tooth block 8 slides along the T-shaped groove 7, thereby driving the sealing block 9 to move. The change in the position of the sealing block 9 adjusts the opening and closing degree of the gas channel, thereby controlling the gas flow rate. When the gas starts to be output, it first passes through the filter screen 14, which removes large impurities. Then the gas enters the filter cotton rod 12 and then enters the controller through the filter base 11. The filter cotton rod 12 further filters the small particles and moisture in the gas, thus solving the problem that traditional flow controllers do not have a filtration system, which may cause particulate matter and other pollutants to remain in the gas. This not only affects the quality of the final product, but may also cause damage or failure of downstream equipment.

[0059] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
