[0031] See also Figures 1 to 7 The utility model shows a jet device, which includes a steering gear 10, and a movable rod 20 rotatably connected to the steering gear 10, a fixed tube 21 is provided at one end of the movable rod 20 away from the steering gear 10, a plurality of elastic buckles 22 are provided in the fixed tube 21, the plurality of elastic buckles 22 are arranged at intervals along the circumferential direction of the fixed tube 21, and the inner space of the plurality of elastic buckles 22 forms an installation cavity; the elastic buckle 22 includes a main body 221 and a buckle part 222 connected to the main body 221, and the outer side surface of the buckle part 222 is a first inclined surface 2221 (such as Figure 3 and Figure 4 shown).

[0032] The jet device also includes a foamer 30, which has a mounting tube 31 and an adjusting tube 32 sleeved on the outer periphery of the mounting tube 31. The foamer 30 may also include an outlet portion connected to one end of the mounting tube 31, and the outlet portion may be a trumpet-shaped structure.

[0033] The mounting tube 31 is used to extend into the mounting cavity of the elastic buckle 22. The inner side surface of the first end of the adjusting tube 32 is provided with a second inclined surface 321 (such as Figure 3 and Figure 4 As shown in the figure, the second inclined surface 321 is used to squeeze the second inclined surface 321 when the adjusting tube 32 moves toward the side of the steering gear 10, so that the elastic buckle 22 fixes the mounting tube 31, so as to realize the rapid installation of the foamer 30, avoid delaying the fire extinguishing time, and improve the fire extinguishing efficiency.

[0034] In some embodiments, the outer circumference of the adjusting tube 32 is provided with an external thread, and the inner circumference of the fixing tube 21 is provided with an internal thread, and the two are threadedly connected. When the adjusting tube 32 moves in the space between the elastic buckle 22 and the inner wall surface of the fixing tube 21, the internal thread and the external thread cooperate with each other, which can improve the connection stability between the adjusting tube 32 and the fixing tube 21, and prevent the adjusting tube 32 from falling out of the fixing tube 21 when the jet device is working.

[0035] In some embodiments, a turntable 322 is disposed on the outer periphery of the second end of the adjusting tube 32 , and a worker rotates the turntable 322 to thereby rotate the adjusting tube 32 back and forth.

[0036] See also Figures 3 to 6 In some embodiments, the mounting tube 31 is further provided with a through groove, which may be an annular through groove, and the through groove may divide the mounting tube 31 into two tube sections.

[0037] Furthermore, a positioning frame 33 is provided on the outer side of the mounting tube 31 at one side of the through groove, and a slide groove 331 extending in the radial direction of the mounting tube 31 is provided on the positioning frame 33, and the slide groove 331 may be a non-through groove; a rotating ring 34 is also provided in the through groove, and a plurality of movable frames 341 are provided on the outer peripheral surface of the rotating ring 34, and the plurality of movable frames 341 are arranged at intervals along the circumferential direction of the rotating ring 34, and a sliding groove 3411 is provided in the movable frame 341, and the sliding groove 3411 is bent and extended in a clockwise direction or a counterclockwise direction. The foamer 30 also includes a plurality of expansion blocks 35, the expansion blocks 35 are located in the sliding groove 3411, and a plurality of mounting shafts 36 are provided on the outer side of the expansion blocks 35, and the two ends of the mounting shafts 36 are respectively located in the slide groove 331 and the sliding groove 3411; the foamer 30 also includes a sealing block 37 for filling the gap between the expansion blocks 35. The sealing block 37 may be a rubber plug, a rubber block, a nylon block, etc.

[0038] The movable frame 341 rotates clockwise or counterclockwise to make the expansion block 35 move up and down in the radial direction, thereby adjusting the cross-sectional area in the mounting tube 31 to adjust the water flow. Understandably, if the water flow cannot be controlled, too much water may be used, thereby wasting water resources. During the fire extinguishing process, if the water flow is too large, it may cause excessive spraying and waste a lot of water resources. Therefore, by setting the expansion block 35 and other structures, the water flow can be appropriately adjusted to save water resources.

[0039] In some embodiments, the expansion block 35 is fan-shaped. Preferably, the number of the expansion blocks 35 can be four, five, six, etc. Of course, the number and structural shape and size of the expansion blocks 35 can be appropriately adjusted according to actual needs, and no specific limitation is made here.

[0040] In some embodiments, the swivel 34 is movably connected to the mounting tube 31 via a bearing, or may be in the form of a slide rail and a slide groove, which is not specifically limited here.

[0041] Combination Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 In some embodiments, a limiting plate 38 is further provided on the mounting tube 31 ; a limiting assembly 39 is further provided on the outer periphery of the rotating ring 34 .

[0042] like Figure 7 As shown, the limiting assembly 39 includes a mounting cylinder 391, an elastic member 392, and a limiting column 393. The mounting cylinder 391 is fixedly connected to the outer circumferential surface of the rotating ring 34. The first end of the limiting column 393 extends into the mounting cylinder 391. The elastic member 392 is disposed in the mounting cylinder 391 and abuts against the end wall of the mounting cylinder 391 and the end wall of the limiting column 393. The second end of the limiting column 393 is used to tightly abut the limiting plate 38.

[0043] Furthermore, the end surface of the limiting plate 38 facing the limiting column 393 is provided with a plurality of limiting holes 381 (such as Figure 1 As shown), a plurality of limiting holes 381 are spaced apart in the circumferential direction of the axis of the end face of the limiting column 393; the second end of the limiting column 393 is provided with a tightening portion 394 for extending into the limiting hole 381, and the first end of the limiting column 393 is provided with a sealing portion 395 for extending into the mounting tube 391.

[0044] The elastic member 392 can make the limiting column 393 stably press against the limiting plate 38. The elastic member 392 can be a coil spring.

[0045] It can be understood that when the limiting column 393 leaves the limiting plate 38, the swivel 34 can rotate, that is, the swivel 34 is in an unlocked state. When the limiting column 393 presses against the limiting plate 38, such as when the pressing portion 394 is located in the limiting hole 381, the swivel 34 cannot rotate, and the swivel 34 is in a locked state.

[0046] In some embodiments, a mounting slot 11 is provided on the steering gear 10, and one end of the movable rod 20 is hinged in the mounting slot 11. The steering gear 10 can be used to control the spray angle and direction of the jet device. For example, the steering gear 10 can achieve precise adjustment of the horizontal and vertical directions of the jet device to achieve accurate tracking and positioning of the fire source.

[0047] The movable rod 20 may have an inner cavity, which may be connected to the fixed pipe 21, the mounting pipe 31, etc. The movable rod 20, the fixed pipe 21 or the mounting pipe 31 may be used to connect a fire extinguishing agent source, such as a water source, a foam source or a dry powder source, etc. The foamer 30 is used to spray fire extinguishing agents such as water, foam, dry powder, etc. to extinguish a fire. Furthermore, the foamer 30 may be used to mix and stir the liquid fire extinguishing agent with air through a series of pipes, pumps, nozzles, etc., to form foam with a fire extinguishing effect.

[0048] In some embodiments, the servo 10 is further provided with a mounting rod 40 , and the mounting rod 40 facilitates the user to mount the servo 10 on a wall.

[0049] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model.
