The inlet pipe 1 and the connecting seat 2 are rotatably connected by a sealed bearing 4. The connecting seat 2 has a water outlet 5 at its center, which communicates with the inlet pipe 1. The lower end face of the connecting seat 2 has a baffle 6, and the baffle 6 has multiple helical teeth 7 evenly distributed along its circumference. The spray head 3 has multiple water outlet grooves 8 distributed along its outer circumference, corresponding to the helical teeth 7. A heat-sensitive glass column 9 is provided between the baffle 6 and the spray head 3. The inlet pipe 1 is inserted into the connecting seat 2 and connected by the sealed bearing 4.

[0029] The lower end face of the connecting seat 2 is provided with a lower edge 10 and an upper edge 11 of the spray head 3. The upper edge 11 and the lower edge 10 are connected and fixed by bolts and nuts.

[0030] The inner diameter of the spray head 3 gradually decreases from top to bottom. The upper outer wall of the spray head 3 is provided with an inclined wall surface 12, which is parallel to the inner wall of the spray head 3. By designing the inclined wall surface 12, the outer diameter of the spray head 3 gradually decreases, allowing the inclined tooth part 7 to enter the water outlet groove 8 and fall down along the water outlet groove 8. The lower part of the spray head 3 is not designed with an inclined wall surface 12 to ensure the thickness of the lower part of the spray head 3 and improve the strength of the spray head 3.

[0031] When the water-blocking cover 6 falls to the middle of the spray head 3, the inner wall of the spray head 3 supports and contacts the water-blocking cover 6. The lowest position of the water-blocking cover 6 is designed to be at the middle of the spray head 3, so that there is space between the bottom of the water-blocking cover 6 and the spray head 3 to accommodate the broken heat-sensitive glass column 9, and to prevent the heat-sensitive glass column 9 from contacting the water-blocking cover 6, which would cause the water-blocking cover 6 to tilt and affect the rotation of the spray head 3 to output water.

[0032] The lower end surface of the water baffle cover 6 is provided with a groove 13, the bottom of the water spraying head 3 is provided with a fixed head 14 corresponding to the groove 13, the fixed head 14 is provided with a positioning groove 15, the top end of the thermal induction glass column 9 is inserted into the groove 13, and the bottom end of the thermal induction glass column 9 is inserted into the positioning groove 15. The thermal induction glass column 9 is fixed through the groove 13 and the positioning groove 15.

[0033] The top end surface of the water baffle cover 6 is provided with a positioning protrusion 16, and the bottom end surface of the connecting seat 2 is provided with a limiting groove 17 corresponding to the positioning protrusion 16.

[0035] The bottom end surface of the connecting seat 2 is a rough surface 19. If the bottom end surface of the connecting seat 2 and the upper end surface of the water baffle cover 6 are smooth and flat, water droplets are easily left between the two surfaces in a humid environment, so that the water baffle cover 6 is adsorbed on the connecting seat 2. Through the design of the rough surface 19, the continuous coverage area of the water film on the contact surface is significantly reduced by the micro-protrusion structure of the rough surface, and the overall adhesion is greatly reduced, so that the water baffle cover 6 can fall smoothly when the thermal induction glass column 9 is broken.

[0036] The outer wall of the water inlet pipe 1 is provided with a thread 20, and the water inlet pipe 1 and the thread 20 are provided with a hexagonal head 21 below. The thread 20 is designed to facilitate the connection of the water inlet pipe 1 and the fire water pipe, and the hexagonal head 21 is designed to facilitate cooperation with a wrench, so that the water inlet pipe 1 can be smoothly connected with the fire water pipe.

[0037] In the utility model, the water baffle cover 6 is pressed against the water outlet hole 5 by the thermal induction glass column 9 to prevent water from flowing out, when the thermal induction glass column 9 is broken, the water baffle cover 6 falls down, because the outer wall of the water spraying head 3 is provided with an inclined wall surface 12, the outer diameter of the water spraying head 3 gradually decreases, the inclined tooth part 7 enters the corresponding water outlet groove 8, the inclined tooth part 7 falls along the water outlet groove 8, at this time, the water outlet groove 8 plays a guiding role on the water baffle cover 6, because the inner diameter of the water spraying head 3 gradually decreases, when the water baffle cover 6 falls to the middle of the water spraying head 3, the inner wall of the water spraying head 3 supports and limits the water baffle cover 6, water falls on the water baffle cover 6 and flows out along the water outlet groove 8, and the water spraying head 3 rotates under the action of water flow.
