[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a filter bag with an adjustable cage mouth structure, including a base 1. A plurality of circular grooves 101 are opened at the side end of the base 1. A through groove 102 is opened at the top end of each circular groove 101. A cage frame assembly is inserted into each circular groove 101. The circular grooves 101 and the through grooves 102 facilitate the limitation of the cage frame assembly. A transmission mechanism is provided at the top end of the base 1. Through the transmission mechanism, each cage frame assembly can be driven to move outward or inward, so as to complete the adjustment of the size of the cage mouth of the cage frame assembly and meet the usage requirements of people. A fixing mechanism is provided at the top end of each cage frame assembly. A filter bag 5 is arranged between the outer ends of each cage frame assembly. After the filter bag 5 is sleeved on the outer ends of each cage frame assembly, the fixing mechanism can facilitate the fixing of the bag mouth of the filter bag 5.

[0021] Please refer to Figure 2 , the cage frame assembly includes a moving rod 2. The moving rod 2 is inserted into the circular groove 101. A connecting plate 201 is fixedly connected to the side end of the moving rod 2. The connecting plate 201 facilitates the limitation between the side ends of the through groove 102 and enables the normal outward or inward movement of the moving rod 2. A round rod 202 is fixedly connected to the top end of the connecting plate 201. The round rod 202 is convenient for being limited in the transmission mechanism. A vertical plate 203 is fixedly connected to the side end of the moving rod 2. The filter bag 5 can be sleeved between the outer ends of each vertical plate 203. A fixing plate 204 is fixedly connected to the top end of the vertical plate 203. The fixing plate 204 and the fixing mechanism cooperate to fix the top end of the filter bag 5. Through the transmission mechanism, the moving rod 2 can be driven to move in the circular groove 101, and a cage mouth is formed between each fixing plate 204. The cage mouth is used for fixing the top end of the filter bag 5, so as to facilitate the adjustment of the size of the cage mouth and be applicable to filter bags 5 of various calibers to meet the usage requirements of people.

[0022] Please refer to Figure 1, the transmission mechanism includes a rotating rod 3. The bottom end of the rotating rod 3 is rotatably arranged at the top end of the base 1. The outer end of the rotating rod 3 is fixedly connected with a circular plate 301. A plurality of inclined slots 302 are opened downward at the top end of the circular plate 301. The circular rod 202 is inserted into the inclined slot 302. The top end of the rotating rod 3 is fixedly connected with a rotating plate 303. By rotating the rotating plate 303, at this time, the rotating plate 303 and the rotating rod 3 drive the circular plate 301 to rotate. At this time, since the circular rod 202 is inserted into the inclined slot 302, when the circular plate 301 rotates, it will drive the circular rod 202 to move in the inclined slot 302 towards the direction close to the outer circle of the circular plate 301. At this time, the circular rod 202 drives the moving rod 2 to move towards the outer end of the circular groove 101. At this time, the vertical plate 203 will gradually move away from the circular groove 101. A circular cage opening is formed between each fixing plate 204 at the top end of each vertical plate 203. At this time, the diameter of this circular cage opening will gradually increase with the movement of the vertical plate 203, so as to facilitate the adjustment of the size of the cage opening, be applicable to filter bags 5 of various diameters, and meet the usage requirements of people.

[0023] Please refer to Figure 1 , the fixing mechanism includes a threaded rod 4. The threaded rod 4 is threadedly connected to the side end of the fixing plate 204. The side end of the threaded rod 4 is fixedly connected with a rotating plate 401. The side end of the threaded rod 4 is fixedly connected with a clamping plate 402. The outer shape of the clamping plate 402 is arc-shaped. The setting of the arc-shaped clamping plate 402 is convenient for cooperating with the fixing plate 204 to fix the top end of the filter bag 5. The side end of the clamping plate 402 is fixedly connected with a guide rod 403. The guide rod 403 is inserted into the side end of the fixing plate 204, which can play a limiting role on the arc-shaped clamping plate 402 and facilitate the normal clamping work of the arc-shaped clamping plate 402. During use, the filter bag 5 is sleeved outside the vertical plate 203, and the top end of the filter bag 5 is fixed between the side ends of the clamping plate 402 and the fixing plate 204. At this time, by rotating the threaded rod 4, the clamping plate 402 is clamped to the side end of the fixing plate 204, and at this time, it is convenient to complete the fixing of the filter bag 5.

[0024] Working principle: For the filter bag 5 with an adjustable cage mouth structure, when in use, by rotating the rotating plate 303, at this time, the rotating plate 303 and the rotating rod 3 drive the circular plate 301 to rotate. At this time, since the circular rod 202 is inserted in the inclined groove 302, when the circular plate 301 rotates, it will drive the circular rod 202 to move in the inclined groove 302 towards the direction close to the outer circle of the circular plate 301. At this time, the circular rod 202 drives the moving rod 2 to move towards the outer end of the circular groove 101. At this time, the vertical plate 203 will gradually move away from the circular groove 101. A circular cage mouth is formed between each fixing plate 204 at the top of each vertical plate 203. At this time, the diameter of this circular cage mouth will gradually increase with the movement of the vertical plate 203. After the adjustment is completed, the filter bag 5 is sleeved outside the outer end of the vertical plate 203, and the top of the filter bag 5 is fixed between the side ends of the clamping plate 402 and the fixing plate 204. At this time, by rotating the threaded rod 4, the clamping plate 402 is clamped on the side end of the fixing plate 204. At this time, the filter bag 5 is fixed, so as to facilitate the adjustment of the size of the cage mouth, be applicable to filter bags 5 of various diameters, and meet the usage requirements of people.
