[0025] The connecting assembly 21 is provided on the outside of the injector body 1 to facilitate the disassembly of the injector body 1. The connecting assembly 21 includes a connecting ring 2110 fixedly installed on the outside of the left and right ends of the injector body 1, and a sealing gasket is fixedly installed on the side of the connecting ring 2110 away from the injector body 1. A first arc plate 212 is movably installed on the outside of the injector body 1, and a fixing plate 214 is fixedly installed on the bottom surface of the first arc plate 212. The front side of the first arc plate 212 is movably hinged with a second arc plate 213, and the opposite sides of the first arc plate 212 and the second arc plate 213 are fixedly installed with a sealing gasket. A second arc groove 2111 is provided on the inner side of the second arc groove 2111, and a connecting plate 215 is fixedly installed on the bottom surface of the second arc groove 2111. A fastening bolt 216 is threadedly installed on the front side of the connecting plate 215. A flange 211 is fixedly installed on the side of the first arc plate 212 away from the injector body 1, and a sealing assembly is provided on the inner side of the first arc plate 212 to prevent water leakage.

[0026] The fastening assembly 22 is arranged on the outside of the injector body 1 to improve the sealing performance of the device. The sealing assembly includes a connecting cylinder 219 fixedly mounted on the inner side of the first arc plate 212. A rubber pad 218 is fixedly mounted on the opposite side of the connecting cylinder 219, and the inner side of the rubber pad 218 is inclined. A first arc groove 217 is opened on the inner side of the first arc plate 212, and a second arc groove 2111 and a sealing groove 2112 are opened on the inner side of the second arc plate 213. The rear end thread of the fastening bolt 216 passes through the front side of the connecting plate 215 and extends to the rear side of the fixing plate 214, and the rotating fastening bolt 216 can be tightened. The first arc plate 212 and the second arc plate 213 are fitted together through the fixing plate 214 and the connecting plate 215. One side of the first arc plate 212 is tightly attached to one side of the second arc plate 213. The outer side of the connecting ring 2110 is tightly attached to the inner side of the first arc groove 217 and the second arc groove 2111. One side of the rubber pad 218 is fixedly installed on one side of the first arc groove 217. The outer side of the connecting tube 219 is tightly attached to the inner side of the sealing groove 2112.

[0027] The fastening bolts 216 and the second arc plate 213 are provided to facilitate the disassembly and replacement of the injector body 1. During disassembly, the fastening bolts 216 are rotated to unscrew them from the inside of the fixing plate 214, and then the second arc plate 213 is lifted up. At this time, the connecting ring 2110 can be taken out from the inside of the first arc groove 217 to disassemble and clean the injector body 1, which facilitates disassembly and improves overall work efficiency.

[0028] The second embodiment is mainly different from the first embodiment in that: the fastening assembly 22 includes a fixing ring 221 fixedly installed at the left and right ends of the outer side of the injector body 1, and movable bolts 222 are threadedly installed on the front and rear sides of the opposite sides of the fixing ring 221. A rubber ring 223 is movably installed on one end of the movable bolt 222, and the side of the rubber ring 223 away from the fixing ring 221 is inclined. One end of the movable bolt 222 is threaded through the opposite side of the fixing ring 221 and is movably installed on one side of the rubber ring 223. One side of the rubber ring 223 movably penetrates the inner side of the first arc plate 212 and the second arc plate 213 and is tightly attached to one side of the connecting ring 2110. Rotating the movable bolt 222 can drive the rubber ring 223 to move so that it is inserted into the inner side of the first arc plate 212 and the second arc plate 213. At the same time, one side of the rubber ring 223 will be tightly attached to one side of the connecting ring 2110 to improve its sealing.

[0029] The sealing performance of the device can be improved by providing a fixing ring 221 and a rubber ring 223. When in use, the injector body 1 is fixed by the connecting assembly 21, and then the movable bolt 222 is rotated to drive the rubber ring 223 to move so that the rubber ring 223 is inserted into the first arc plate 212 and the second arc plate 213. At this time, the outer side of the rubber ring 223 will be tightly attached to the inner side of the first arc plate 212 and the second arc plate 213, and at the same time, one side of the rubber ring 223 will be tightly attached to one side of the connecting ring 2110, avoiding water leakage and having good practicality.

[0030] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0031] When in use, the user connects the flange 211 to the water pipe assembly, then picks up the injector body 1 and places the connecting ring 2110 inside the first arc groove 217, then covers the second arc plate 213 and rotates the fastening bolt 216 through the inside of the fixing plate 214 to make the second arc plate 213 and the first arc plate 212 close together, at this time the rubber pad 218 will be close to the inner side of the second arc groove 2111, then rotates the movable bolt 222 to drive the rubber ring 223 to move so that the rubber ring 223 is inserted into the first arc plate 212 and the first arc plate 212. Inside the second arc plate 213, the outer side of the rubber ring 223 will be tightly attached to the inner side of the first arc plate 212 and the second arc plate 213, and at the same time, one side of the rubber ring 223 will be tightly attached to one side of the connecting ring 2110. At this time, it can be used. When the injector body 1 needs to be disassembled for cleaning, the fastening bolt 216 is rotated in the reverse direction to unscrew it from the inside of the fixing plate 214, and then the second arc plate 213 is lifted up. At this time, the connecting ring 2110 can be taken out from the inside of the first arc groove 217 to disassemble and clean the injector body 1.
