[0024] 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.

[0025] like Figures 1-4 As shown, this embodiment provides a technical solution: a splash-proof nozzle with replaceable filter cartridges, including a housing 1 and a nozzle body 2. A filter cartridge replacement structure 3 is provided between the housing 1 and the nozzle body 2. The filter cartridge replacement structure 3 includes a rectangular plate 31, with a rectangular through groove 33 on one side of the rectangular plate 31. A filter frame 34 is inserted into the inner wall of the rectangular through groove 33. An auxiliary connection structure 4 is provided at the connection between the housing 1 and the nozzle body 2. The auxiliary connection structure 4 includes a rectangular ring frame 41, with one side of the rectangular ring frame 41 fixedly connected to one side of the nozzle body 2. By providing the filter cartridge replacement structure 3, under the action of the filter frame 34, it can be engaged and fixed with the rectangular through groove 33. The filter element 35 can be inserted into the inner wall of the nozzle body 2. At the same time, the rectangular locking block 38 can be engaged with the rectangular locking groove 32, thereby providing auxiliary positioning for the filter element 35.

A threaded locking rod 45 is threadedly connected to the inner wall of the first screw hole 43 and the second screw hole 44. Under the action of the rectangular ring block 42 and the rectangular ring frame 41, the outer shell 1 and the suction nozzle body 2 can be connected. At the same time, under the action of the threaded locking rod 45, the rectangular ring block 42 and the rectangular ring frame 41 can be engaged and fixed in conjunction with the first screw hole 43 and the second screw hole 44.

[0029] Working principle:

[0030] like Figure 1-4 As shown:

[0031] When in use: Insert the filter frame 34 into the inner wall of the rectangular through groove 33. At this time, the filter element 35 will be snapped into the inner wall of the mouthpiece body 2. Then, snap the rectangular clip 38 into the rectangular slot 32. During the insertion process, the smoke guide tube 36 will be snapped into and out of the inner wall of the smoke tray 310. At this time, the rectangular insert 37 can be inserted into the inner wall of the rectangular slot 39.

[0032] At this time, the rectangular ring clamp 42 can be engaged with the rectangular ring clamp frame 41. Then, the threaded clamp rod 45 is fixed with the first screw hole 43 and the second screw hole 44, making the fixation more stable.
