[0017] In the present invention, the water spraying mechanism includes an annular tube 3 arranged on the bottom surface of the shell 2, circular tubes 5 arranged on both sides of the bottom surface of the shell 2 and a circular hollow plate 35 rotatably arranged in the circular tube 5, a water outlet A33 is opened on the outer wall of one side of the circular hollow plate 35, a water outlet B is opened on the outer wall of the circular tube 5 to match the water outlet A33, a connecting pipe 15 is provided on one side of the water outlet B, and one end of the connecting pipe 15 is connected to the annular tube 3, a plurality of water outlet holes 39 are evenly opened on the inner wall of the annular tube 3, a connecting head 37 is provided on the top surface of the circular hollow plate 35, the top of the connecting head 37 is fixedly connected to the hollow tube 28 in the driving component, and the connecting head 37 is connected to the hollow tube 28, and an installation groove is opened in the middle of the bottom surface of the circular hollow plate 35, and a conductive component is arranged in the installation groove.
[0018] In the present invention, the conductive component includes a glass 46 arranged on the bottom surface of the circular tube 5, a copper plate B34 arranged in the mounting groove and a guide rod 32 symmetrically arranged on both sides of the bottom surface of the circular hollow plate 35, a movable plate 29 is slidably arranged on the outer wall of the guide rod 32, a copper plate A30 is arranged on the top surface of the movable plate 29, a limit plate is arranged on the bottom of the guide rod 32, an extrusion spring 36 is sleeved on the outer wall of the guide rod 32 between the movable plate 29 and the limit plate, and a nylon rope 31 is arranged between the movable plate 29 and the glass 46; wherein, the copper plate A30, the copper plate B34, the micro motor 6 and the external power supply form a series circuit through a wire; and the above-mentioned glass 46 is ordinary glass. When the external temperature is greater than 70°, the external temperature is too high and the temperature inside the glass 46 is too low, which will cause the glass 46 to break, and then under the action of the extrusion spring 36, the copper plate A30 and the copper plate B34 are brought into contact, and at this time, the micro motor 6 is powered on and works.
[0019] In the present invention, a strip groove is provided at the bottom of the water inlet 22, and the sealing mechanism includes an L-shaped sealing plate 23 arranged in the strip groove, one end of the L-shaped sealing plate 23 movably passes through the strip groove, a reset spring B24 is provided between the L-shaped sealing plate 23 and the strip groove, an arc block A25 is provided on one side of the top surface of the L-shaped sealing plate 23, a turntable 27 is provided on the outer wall of the hollow tube 28 in the driving assembly, and an arc block B45 is provided at the edge of one side of the bottom surface of the turntable 27 to cooperate with the arc block A25.
[0020] In the present invention, a strip sealing block 42 is provided at the front and rear ends of the L-shaped sealing plate 23, and a strip sealing groove is formed in the strip groove at the front and rear ends to cooperate with the strip sealing block 42, and the cross-sections of the strip sealing block 42 and the strip sealing groove are both rhombus-shaped. By using the angular strip sealing block 42, it is convenient to increase the contact area between the strip sealing block 42 and the strip sealing groove, thereby facilitating the improvement of the sealing performance of the L-shaped sealing plate 23 and the water inlet 22.
[0021] Working principle: When the present invention is used, it includes the following steps: Step 1: When a fire occurs outside, the temperature outside is too high, so the glass 46 is broken under high temperature. At this time, the movable plate 29, under the action of the extrusion spring 36, makes the copper plate A30 and the copper plate B34 contact. At this time, the micro motor 6 is powered on and works, and the output shaft of the micro motor 6 rotates to drive the circular plate 8 to rotate, and then drives the short cylinder 44 to rotate, thereby driving the annular plate 43 to move back and forth, and further drives the connecting rod 10 to move back and forth, thereby driving the piston A11 to move back and forth in the sealing chamber 9; Step 2: When the piston A11 moves to the sealed cavity 9 near one end of the micro motor 6, the air in the air guide groove will be pumped into the sealed cavity 9, and then the hot air in the housing 2 will enter the air guide groove and finally enter the sealed cavity 9, so as to achieve heat dissipation of the sound and light alarm body 4, thereby improving the service life of the sound and light alarm body 4; when the piston A11 moves to the sealed cavity 9 away from one end of the micro motor 6, at this time, the air in the sealed cavity 9 will be transported to the L-shaped groove 19; Step 3: When wind enters the L-shaped groove 19, it pushes the piston B20 to move downward, thereby driving the circular rod 18 and the connecting column 41 to move downward. The connecting column 41 moves in the spiral groove 40, which causes the hollow tube 28 to rotate, thereby driving the connecting head 37 and the circular hollow plate 35 to rotate; wherein, when the piston B20 moves to the bottom of the pressure relief groove 16 at the bottom of the L-shaped groove 19, the air in the L-shaped groove 19 enters the water storage tank 9 through the pressure relief groove 16, and then the piston B20 is reset under the action of the reset spring A17, which can further reverse the hollow tube 28, thereby reversing the connecting head 37 and the circular hollow plate 35; Step 4: When the circular hollow plate 35 rotates, when the water outlet A33 coincides with the water outlet B, at this time, the water in the water storage chamber 13 enters the hollow tube 28 through the circular opening 38 at the bottom of the hollow tube 28, and finally falls into the circular hollow plate 35 through the bottom of the hollow tube 28, and then enters the connecting pipe 15 through the water outlet A33 and the water outlet B, and the water enters the annular tube 3. Finally, the water falls on the surface of the bottom of the sound and light alarm body 4 through the water outlet hole 39, so that water is sprayed on the outer wall of the bottom of the sound and light alarm body 4, which is further convenient for heat dissipation of the sound and light alarm body 4 and improves the service life of the sound and light alarm body 4; when the water outlet A33 and the water outlet B of the circular hollow plate 35 do not coincide, at this time, the water in the circular hollow plate 35 does not flow outward, so that the sound and light alarm body 4 is sprayed with water at intervals, thereby saving water resources; Step five: When the hollow tube 28 rotates, the turntable 27 rotates, thereby driving the arc block B45 to rotate. When the arc block B45 contacts the arc block A25, it will drive the arc block A25 to move downward, thereby driving the L-shaped sealing plate 23 to move downward, thereby separating the L-shaped sealing plate 23 from the water inlet 22, making it easier for water to enter the water storage chamber 13 from the water inlet 22, thereby facilitating water replenishment into the water storage chamber 13; when the arc block B45 and the arc block A25 are separated, the L-shaped sealing plate 23 will overlap with the water inlet 22 under the action of the reset spring B24, thereby blocking the water inlet 22, thereby improving the sealing at the water inlet 22.
[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
