[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] Please refer to the attached Figures 1-4As shown in the figure, a fire sprinkler in an integrated perfluoropentanone energy storage fire extinguishing system provided by an embodiment of the present utility model includes a housing 1, a sprinkler head body 2, a piston 3, an electric head 6, a reset member 5, and an air inlet joint 4. A sliding channel 11 is provided in the housing 1. The sprinkler head body 2 is provided at one end of the housing 1 and communicates with and seals the corresponding end of the sliding channel 11. The electric head 6 is provided at the other end of the housing 1 and is located in the corresponding sealed end of the sliding channel 11. The piston 3 is provided in the sliding channel 11 between the electric head 6 and the sprinkler head body 2 and is slidably and sealingly contacted in the sliding channel 11. An air cavity 31 opening towards the sprinkler head body 2 is provided in the piston 3. A circle of air passing grooves 32 is provided on the outer ring wall of the piston 3. At least one air passing hole 33 is provided between the air passing grooves 32 and the air cavity 31. An installation hole 12 is provided in the middle of the housing 1. The air inlet joint 4 is installed in the installation hole 12 to communicate with the sliding channel 11. The reset member 5 acts axially on the piston 3. When the electric head 6 works, it can generate high-pressure gas to push the piston 3 to move towards the sprinkler head body 2 end, so that the air inlet joint 4 aligns with the air passing grooves 32 to open the system; when the electric head 6 stops working, the reset member 5 pushes the piston 3 to move towards the electric head 6 end, so that the air inlet joint 4 aligns with the outer wall of the piston 3 to close the system.

[0025] The reset member is set as a reset spring. One end of the reset spring abuts against the bottom of the air cavity 31 in the piston 3, and the other end abuts against the sprinkler head body 2. Such a design just uses the space of the air cavity 31 to arrange the reset spring. On the one hand, it saves space, and on the other hand, the reset spring will not affect the air flow. Therefore, this structural design can make the structure simpler. Optionally, the installation between the air inlet joint 4 and the installation hole 12 is set as a quick plug-in connection.

[0026] The sealing contact between the piston 3 and the sliding channel 11 includes: a plurality of sealing grooves 34 are provided on the outer wall of the piston 3, sealing rings 35 are provided in the sealing grooves 34, and the outer diameter of the piston 3 is set to be adapted to the diameter of the sliding channel 11, so that the sealing rings 35 abut against the inner wall of the sliding channel 11.

[0027] The sprinkler head body 2 is detachably connected to the housing 1. As a specific embodiment of one of the detachable connections, a first threaded hole 13 adapted to the sprinkler head body 2 is provided at the first end of the housing 1. A first thread 24 is provided on the outer circumference of the sprinkler head body 2. The sprinkler head body 2 is screwed onto the housing 1 by adapting the first thread 24 to the first threaded hole 13.

[0028] It also includes a cover 7, which is arranged at the end of the shell 1 and is used to seal the sliding channel 11 at the opposite end of the nozzle body 2 to form a closed end of the sliding channel 11 at this end, and the electric blasting head 6 is installed on the cover 7. Similarly, the cover 7 is detachably connected to the shell 1. As one specific embodiment of the detachable connection, the second end of the shell 1 is provided with a second threaded hole 24 adapted to the cover 7, and the outer periphery of the cover 7 is provided with a second thread 71, and the cover 7 is screwed to the shell 1 through the second thread 71 and the second threaded hole 24.

[0029] The outer end of the nozzle body 2 is provided with a nozzle 21, and the inner end of the nozzle body 2 is provided with a core valve cavity 22 connected to the nozzle 21, and a swirl core 23 is provided in the core valve cavity 22. The swirl core 23 includes a core body, a core hole 231 is provided in the center of the core body, and a plurality of spaced oblique air guide grooves 232 are provided on the outer periphery of the core body.

[0030] Its working principle is: when not in use, the return spring is in an expanded state. In this state, the air intake connector 4 (the air intake connector 4 is connected to the perfluorohexanone storage device of the fire extinguishing system, and the perfluorohexanone can be sprayed out through the air holes on the air intake connector 4 when connected to the nozzle 21) is aligned with the outer wall of the piston 3, and the outer wall of the piston 3 refers to the position of the air groove 32 on the outer wall of the piston 3. Therefore, at this time, the air hole of the air intake connector 4 is blocked by the outer wall of the piston 3, and the fire extinguishing system is in a closed state. When the fire extinguishing system needs to be used, that is, when the fire extinguishing system needs to be activated, the electric blasting head 6 is first electrically activated. At this time, the electric blasting head 6 generates high-pressure gas, so that the air pressure at the rear end of the piston 3 (located at one end of the electric blasting head 6) is higher than that at the front end of the piston 3 (located at one end of the nozzle body 2), thereby pushing the piston 3 to move toward one end of the nozzle body 2, and in the process of the piston 3 moving toward one end of the nozzle body 2, the air intake connector 4 can be aligned with the air groove 32, so that the air hole on the air intake connector 4 passes through the air groove 32 to the air hole 33 and then passes through the air cavity 31 in the piston 3 to connect to the nozzle body 2, thereby realizing that the other in the perfluorohexanone storage device is ejected from the nozzle body 2 to achieve the system opening state. On the contrary, the electric blasting head 6 stops working, and the reset member 5 pushes the piston 3 to move toward one end of the electric blasting head 6, so that the air intake connector 4 is aligned with the outer wall of the piston 3 to close the system, which will not be repeated here.

[0031] In summary, the fire sprinkler in the integrated perfluorohexanone energy storage fire extinguishing system of the utility model includes a sprinkler body 2 for spraying, and a piston 3 for controlling the opening or closing of the system, which slides in a sliding channel 11, so that the fire sprinkler integrates the opening and closing functions and the spraying functions, that is, the two components of the traditional puncture valve and the sprinkler are made into one component, thereby simplifying the structure and making installation more convenient.

[0032] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.
