in this embodiment, the water intake assembly 1 comprises a sealing gasket 11; a water inlet nut 12; a clasp 13; an O-ring seal 14; a movable joint 15; a spring 16; a water stop 17; a threaded joint 18; a water inlet core 19;

as shown in fig. 3 to 7, the joint portion 194 of the water inlet core 19 is completely sleeved into one end of the hose body 4 and is pressed by the steel sleeve 3, so that the water inlet core 19 is prevented from falling off and plays a role in sealing; the external thread 182 is matched and screwed with the internal thread 192 of the water inlet core 19 by using a spanner through the spanner position 181 of the threaded joint 18 until the thread end surface 183 of the threaded joint 18 is flatly attached to the inner end surface 193 of the water inlet core 19; the inner hole 171 of the water stop 17 is engaged with the first inner groove 184 of the screw joint 18; one end surface of the spring 16 takes the main end surface 185 of the threaded joint 18 as a supporting surface, and the other end surface of the spring 16 is matched with the middle end surface 152 of the movable joint 15 and supports the movable joint 15 by the elasticity of the spring 16; the O-shaped sealing ring 14 is sleeved into the second inner groove 151 of the movable joint 15 and forms a seal with the inner wall 195 of the water inlet core 19; the clamping ring 13 is embedded into the clamping groove 191 of the water inlet core 19 to prevent the movable joint 15 from being ejected out due to the elasticity of the spring 16; the clamping portion 196 of the water inlet core 19 is clamped with the water inlet nut 12.

The use process of the explosion-proof hose comprises the following steps: as shown in fig. 8, when the water pressure is normal, when the water flow passes through the movable joint 15, the upstream-downstream water pressure difference value is smaller, the movable joint 15 is not moved or moves towards the downstream of the water flow for a short distance against the elastic force of the spring 16, the water flow cannot influence the water flow, and the water flow flows to the threaded joint 18 through the inner hole of the movable joint 15 and flows into the hose body 4 through the 4 water inlet holes 186 thereof;

as shown in fig. 9, when the water pressure suddenly rises, the upstream-downstream water pressure difference value of the movable joint 15 becomes larger, the movable joint 15 is pushed to move towards the downstream of the water flow against the elastic force of the spring 16, and the lower end face 153 of the movable joint 15 abuts against the end face of the water stop member 17 to seal the water inlet 186 of the threaded joint 18, so that the water is stopped, and the explosion-proof effect is achieved.

The water outlet component 2 of the hose can be a nut component used on a closestool or a joint component used on a faucet.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model.
