[0029] 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.

[0030] In the description of this utility model, it should be noted that the terms "vertical," "upper," "lower," and "horizontal," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0032] like Figures 1 to 4The figure shows a fire alarm sprinkler device according to the present invention, used for fire safety. It includes a housing 10, a smoke detection assembly 20, and a sprinkler assembly 30. The housing 10 defines a cavity 11 on its inner side, a vertical through-hole 12 on its outer wall, and a horizontal air vent 13 on its outer wall that communicates with the cavity 11. The smoke detection assembly 20 is located within the cavity 11 and includes an electrically connected smoke sensor 21, a control chip 22, and a battery 23. The sprinkler assembly 30 includes a water outlet pipe 31 inserted into the through-hole 12, a plug 32 connected to the outlet of the water outlet pipe 31, and a glass body 33 connected to the end of the plug 32 facing away from the water outlet pipe 31. The glass body 33 is filled with an expansion medium that expands when heated. A heating wire 35 is located on the outer side of the glass body 33 and is electrically connected to the battery 23. The housing 10 is mounted high in the room, and the water outlet pipe 31 is connected to the fire water supply.

[0033] When a fire occurs, the ambient smoke concentration increases, and the smoke enters the cavity 11 through the air vent 13; the smoke sensor 21 senses the increase in ambient smoke concentration and outputs an electrical signal to the control chip 22, which controls the battery 23 to power the heating wire 35; the heating wire 35 generates heat, causing the expansion medium to expand, thereby causing the vitreous body 33 to rupture; at this time, there is no blockage, and fire-fighting water is sprayed out through the water outlet pipe 31, achieving the purpose of spraying to alleviate the fire.

[0034] A further improvement to the above solution is that the housing 10 includes a connecting base plate 14 and a protective cover 15 disposed at the lower end of the connecting base plate 14. A perforation 12 vertically penetrates the connecting base plate 14 and the protective cover 15. A vent 13 is provided on the outer wall of the protective cover 15. The connecting base plate 14 is secured to a high position indoors using expansion screws or the like. The protective cover 15 is disposed outside the smoke detector assembly 20 to provide protection.

[0035] A further improvement to the above scheme is that the air vent 13 is in the shape of an elongated strip, and a plurality of air vents 13 are provided and distributed in a circular array on the outer wall of the protective cover 15 to increase the contact area between the cavity 11 and the outside world, so that smoke can enter through the air vents 13 during a fire, thereby ensuring the accuracy of smoke detection.

[0036] A further improvement to the above solution is that the smoke detection assembly 20 also includes a circuit board 24, to which the smoke sensor 21, control chip 22, and battery 23 are all soldered. A support column 241 is also provided on the side of the circuit board 24 facing away from the smoke sensor 21. The other end of the support column 241 is connected to the connecting base 14. The support column 241 keeps the circuit board 24 away from the connecting base 14, preventing moisture from contacting the circuit board 24 when the wall is damp, which could affect the normal operation of the smoke detection assembly 20 and thus ensure fire safety.

[0037] A further improvement to the above scheme is that the fire alarm sprinkler device of the present invention also includes a speaker 25 and a light-emitting module 26 soldered on the circuit board 24; the speaker 25 and the light-emitting module 26 are both electrically connected to the control chip 22; when a fire occurs, the smoke sensor 21 detects that the ambient smoke concentration reaches a preset value, and transmits an electrical signal to the control chip 22. After receiving the electrical signal, the control chip 22 starts the speaker 25 and the light-emitting module 26, and emits an alarm and light to serve as a warning.

[0038] A further improvement to the above scheme is that the smoke sensor 21 can be optionally a photoelectric smoke sensor 21, which includes an LED light-emitting module 26 and a receiving module; under normal conditions, the light from the LED light-emitting module 26 is emitted horizontally, and the receiving module cannot receive the light from the LED light-emitting module 26; when a fire occurs, under the refraction of the smoke, the light from the LED light-emitting module 26 is refracted and then emitted toward the receiving module, and the receiving module outputs an electrical signal to the control chip 22.

[0039] A further improvement to the above solution is that the smoke sensor 21 can be an ionization smoke sensor. Using radioactive materials to generate ionized air, when smoke enters the ionization smoke sensor 21, the smoke particles hinder the transmission of ions, thereby changing the flow of current. When the current change exceeds a set threshold, it triggers and outputs an electrical signal.

[0040] A further improvement to the above solution is that a pipe joint 36 is connected to the end of the water outlet pipe 31 away from the plug 32, and the pipe joint 36 is used to be connected to the fire protection pipe.

[0041] Compared with the prior art, the fire alarm sprinkler device involved in the present invention can quickly start spraying, has a fast response speed, and effectively alleviates the fire; it is specifically provided with a smoke detection component 20 and a sprinkler component 30, wherein the smoke detection component 20 includes a smoke sensor 21 and a control chip 22; and the sprinkler component 30 includes a water outlet pipe 31, a glass body 33 and a heating wire 35; when a fire occurs, the smoke sensor 21 can quickly sense the ambient smoke and start the heating wire 35 through the control chip 22. Under high temperature conditions, the expansion medium in the glass body 33 expands and causes the glass body 33 to rupture, and fire-fighting water can be sprayed out from the water outlet pipe 31, which plays a role in alleviating the fire and extinguishing the fire; using smoke detection as the starting condition of the sprinkler component 30 has a fast response speed, and can start the sprinkler component 30 before the fire becomes further aggravated, thereby controlling the fire in advance.

[0042] The above merely represents the preferred technical solution of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
