[0037] The following is for reference Figures 1 to 5 The present invention will be described as follows:

[0038] A switchable injection connector, such as Figure 1 As shown, the device includes a switching valve body 10, which includes a valve hole 101 and an inlet 102, a first outlet 103, and a second outlet 104 respectively communicating with the valve hole 101; a movable valve stem 20 is provided in the valve hole 101; the first outlet 103 is connected to a first conversion connector 50, and the second outlet 104 is connected to a second conversion connector 40 through a gun barrel 30.

[0039] In use, the inlet is connected to a water pipe, the first adapter can be connected to a cleaning fluid spray bottle for spraying cleaning fluid, and the second adapter can be connected to different spray heads to meet different working conditions. By moving the valve stem, the inlet can be connected to the first or second outlet to meet the needs of spraying cleaning fluid or water, thus facilitating the work of spraying water and cleaning fluid without the need for a separate equipment for spraying cleaning fluid.

[0040] like Figures 1-5 As shown, the valve orifice 101 in this embodiment includes an integrally formed left large diameter orifice 1011, left middle diameter orifice 1012, small diameter orifice 1013, right middle diameter orifice 1014, and right large diameter orifice 1015; the first outlet 103 is connected to the left middle diameter orifice 1012, the second outlet 104 is connected to the right middle diameter orifice 1014, and the inlet 102 is connected to the small diameter orifice 1013;

The valve stem seat 21 has an outer small diameter hole 211 and an inner large diameter hole 212 formed inside. A liquid passage hole 213 communicating with the inner large diameter hole 212 is formed in the middle of the valve stem seat 21. An inner sealing head 214 that mates with the small diameter hole 1013 is formed at the inner end of the valve stem seat 21. The inner sealing head 214 is inserted into the small diameter hole 1013.

[0042] The valve rod 20 comprises a rod body 201 matched with the outer small-diameter hole 211, and a convex stop ring 202 is formed in the middle part of the rod body 201; a pair of grooves 203 are formed in the rod body 201 and symmetrically arranged relative to the stop ring 202;

[0043] The two ends of the rod body 201 are respectively inserted into the outer small-diameter holes 211 of the two valve rod seats 21.

[0044] When the valve rod moves right, the convex platform abuts against the end of the inner large-diameter hole of the right valve rod seat, thereby preventing water from flowing out of the inner large-diameter hole of the right valve rod seat; at this time, the water of the water inlet enters into the small-diameter hole, and then enters into the inner large-diameter hole of the left valve rod seat through the gap between the outer wall of the groove 203 and the inner large-diameter hole of the left valve rod seat, and then flows out through the liquid passage of the left valve rod seat and enters into the first water outlet, and finally flows out from the first conversion joint;

[0046] The rod body 201 of the embodiment is formed with two symmetrically arranged sealing grooves 204 near the stop ring 202, and a sealing ring 23 is sleeved in the sealing groove 204.

[0047] The sealing ring can increase the sealing property between the cylinder body and the inner large-diameter hole, thereby preventing water from flowing out of the inoperative part.

[0048] The outer end of the rod body 201 is sleeved with an O-ring 24, which abuts against the inner wall of the outer small-diameter hole 211, so as to further improve the sealing property between the rod body and the valve rod seat, prevent water from leaking out, and meanwhile, the O-ring can increase the friction resistance between the valve rod and the valve rod seat, thereby preventing the valve rod from freely moving and affecting the spraying effect.

[0049] The groove 203 of the embodiment is formed with a guide conical surface 205 at one end near the stop ring 202, and the guide conical surface can facilitate the moving work of the valve rod.

[0050] As shown in Figure 1 The two ends of the rod body 201 of the embodiment extend out of the conversion valve body 10 and are respectively fixed with a switching pressing part 22.

[0051] The switching pressing part is installed at the two ends of the cylinder body, so as to facilitate the left and right moving work of the valve rod, thereby facilitating the switching work.

[0052] As shown in Figure 1 The second water outlet 104 of the embodiment is obliquely arranged; and the gun barrel 30 is a bent pipe, and the bending arrangement can make room, thereby avoiding the interference between the components of the cleaning liquid spraying pot installed with the first conversion joint and the gun barrel.

[0053] AsFigure 1 As shown, the first conversion joint 50 and the second conversion joint 40 of the embodiment are arranged in parallel, and the spraying directions of the corresponding spray pots or spray heads mounted on the two conversion joints can be kept consistent, thereby facilitating the cleaning work.

[0054] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and the above assumptions of these improvements and modifications should be considered as the protection scope of the present application.
