Description

Technical Field

[0001] The utility model relates to a flush type sprinkler head, belonging to the technical field of fire fighting equipment. Background Art

[0002] Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, water is sprayed out through the sprinkler head splash plate to extinguish the fire. They are divided into pendent sprinkler heads, upright sprinkler heads, ordinary sprinkler heads, side wall sprinkler heads, etc.

[0003] For example, CN219323818U discloses a flush-mount sprinkler head that offers the same aesthetic appeal as concealed sprinklers, but with an unenclosed temperature sensor and all internal components instantly released upon activation. This makes it a perfect alternative to concealed sprinklers. Its two-stage telescopic function significantly reduces the body length, resulting in an elegant overall design. It activates smoothly with a slight damping sensation, and after activation, the two-stage extension function allows the deflector plate to extend to its effective length, ensuring optimal sprinkler performance.

[0004] However, after the temperature sensing element breaks, the nozzle body will fall and many supporting parts will fall off. These supporting parts are easy to be lost after falling and are difficult to recycle, which increases the cost of use. In addition, in the early stage of a fire, due to the low indoor temperature, the temperature sensing element cannot detect in time. It is often only after the fire range increases and a large amount of property is lost that it breaks and triggers the nozzle to spray water, thereby increasing economic losses.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1-Figure 5 , the utility model provides a technical solution:

[0026] A flush sprinkler comprises a nozzle body 1, a threaded connector 2 is provided above the nozzle body 1, a connecting block 3 is fixedly connected to one side of the nozzle body 1, one end of the connecting block 3 is fixedly connected to an infrared sensor 4, connecting brackets 5 are fixedly connected to both sides below the nozzle body 1, the bottom of the connecting bracket 5 is fixedly connected to a fixed support 6, the bottom of the fixed support 6 is connected to a splash plate 7, the bottom of the splash plate 7 is fixedly connected to a motor box 8, and a guide pipe 9 is connected to the center above the fixed support 6.

[0027] Specifically, the fixed support 6 is truncated cone-shaped, the guide tube 9 passes through the inside of the fixed support 6, and the bottom of the guide tube 9 is on the same horizontal line as the bottom of the fixed support 6. The motor box 8 is provided with thermal insulation cotton 10 around the inside, and the thermal insulation cotton 10 is provided with a drive motor 11. The output end of the drive motor 11 is connected to a screw 12, and the screw 12 is connected to the inside of the threaded tube 13. The thermal insulation cotton 10 can isolate the external temperature outside the drive motor 11, thereby reducing the influence of the external ambient temperature on the drive motor 11.

[0028] Specifically, a guide strip 14 is fixedly connected to one side of the outer side of the threaded tube 13, and a groove for accommodating the guide strip 14 is opened inside the guide tube 9. The threaded tube 13 and the guide strip 14 are slidably connected inside the guide tube 9. The top of the threaded tube 13 is fixedly connected to the top block 15, and a rubber sealing gasket 16 is fixedly connected above the top block 15. The top of the rubber sealing gasket 16 is conical, and the top of the threaded tube 13 extends to the inside of the nozzle body 1. The rubber sealing gasket 16 and the top block 15 are both circular, and the rubber sealing gasket 16 and the top block 15 have the same diameter. The nozzle body 1 is provided with a groove for accommodating the top block 15 and the rubber sealing gasket. The water tank 17 has the same diameter as the sealing gasket 16, and the top block 15 is slidably connected to the rubber sealing gasket 16 inside the water tank 17. An isolation gasket 18 is provided inside the water tank 17, and the bottom of the isolation gasket 18 is in conflict with the rubber sealing gasket 16. The bottom of the isolation gasket 18 is provided with a connecting groove adapted to the rubber sealing gasket 16. The guide strip 14 can prevent the threaded tube 13 from rotating with the screw 12 when moving up and down in the guide tube 9, so that the threaded tube 13 can move up and down stably. After the rubber sealing gasket 16 is in conflict with the isolation gasket 18, the water tank 17 can be sealed, so that the nozzle body 1 can be closed, thereby controlling the opening and closing of the nozzle body 1.

[0029] Example 2: Please refer to Figure 1 、 Figure 3 The difference between this embodiment and embodiment 1 is that a controller 19 is provided above the infrared sensor 4, the input end of the controller 19 is electrically connected to the output end of the infrared sensor 4 through a wire, and the output end of the controller 19 is electrically connected to the output end of the drive motor 11 through a wire. The infrared sensor 4 can detect the fire point and, when the fire range is small, start the drive motor 11 through the controller 19 to open the sprinkler body 1 to spray water to extinguish the fire, thereby reducing economic losses.

[0030] The working principle of the present utility model is as follows: when in use, the infrared sensor 4 can detect the fire point. When a fire occurs, the controller 19 can receive the information of the infrared sensor 4 and then start the drive motor 11. When the drive motor 11 is running, it drives the screw 12 to rotate. When the screw 12 rotates, it can drive the threaded tube 13 to move downward. When the threaded tube 13 moves downward, it can drive the top block 15 and the rubber sealing gasket 16 to move downward. When the rubber sealing gasket 16 is removed from under the isolation gasket 18, the water in the fire water pipe can flow and spray toward the splash plate 7 through the water tank 17, so as to perform the fire extinguishing operation in time. Moreover, after the fire extinguishing is completed, the top block 15 and the rubber sealing gasket 16 can be moved upward again by starting the drive motor 11 to reset them to contact the isolation gasket 18 to seal the water tank, which is convenient for recycling the nozzle body 1 and saving usage costs.
