Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Please refer to fig. 2, a fire sprinkler head with alarm function, including base 1, the equal fixedly connected with in the bottom both sides of base 1 grips arm post 2, the bottom fixedly connected with of gripping arm post 2 splashes water tray 3, the top fixed mounting of splashes water tray 3 has glass pipe 4, the top fixedly connected with mount pad 5 of glass pipe 4, the top fixedly connected with sealing plug 6 of mount pad 5, mount pad 5 and sealing plug 6 are used for the bottom shutoff of base 1. An air inlet channel 7 communicated with the inside and the outside is formed in the base 1, the air inlet channel 7 is inclined from top to bottom, an air vibration channel 8 is formed in one side of the base 1, and the air vibration channel 8 is used for communicating the inner cavity of the air inlet channel 7 with the external environment. When the mounting seat 5 is tightly pressed by the glass tube 4, the lower port of the air inlet channel 7 is sealed by the sealing plug 6.

Example two

Referring to fig. 3 to 4, a fire sprinkler with alarm function, different from the first embodiment, includes: air inlet channel 7 and gas shake passageway 8 parallel arrangement, air inlet channel 7 and gas shake passageway 8 are through gas shake chamber 9 intercommunication, are equipped with reed 10 in the inside of gas shake chamber 9, and the inner bottom of base 1 is by the upper to lower internal diameter increase gradually, and the shape of sealing plug 6 and the inner chamber shape looks adaptation of base 1, and air inlet channel 7 and gas shake passageway 8 are located the different internal diameter sections of base 1 respectively.

When water flow in the base 1 is sprayed down, the flow speed is reduced from a small diameter to a large diameter, so that the pressure is reduced, the air pressure at the air inlet channel 7 and the air vibration channel 8 is unbalanced, the kicking vibration occurs due to unbalance in the air flow entering process, the reed 10 is driven to vibrate, and the sound is enhanced in the whole vibration process.

Wherein, the inner diameter of the air inlet channel 7 is gradually decreased from outside to inside. The vibration frequency is higher and the sound is larger after the external air enters the air inlet channel 7, and meanwhile, the high-frequency vibration can drive the reed 10 to vibrate at a high frequency, so that the sound is further enhanced.

EXAMPLE III

Referring to fig. 5, a fire sprinkler head with an alarm function is different from the second embodiment in that: in the second embodiment, the inner bottom of the base 1 is inverted, in order to achieve the sealing effect of the air inlet channel 7, the lower port of the air inlet channel 7 is provided with the sealing plug 11, and meanwhile, the sealing plug 11 is fixedly connected to the top end of the sealing plug 6 through a string, so that when the sealing plug 6 falls off, the sealing plug 11 is driven to fall off.

By adopting the shape arrangement after inversion, the flow speed is accelerated by changing from a large caliber to a small caliber in the falling process of the water flow, so that the pressure intensity is obviously reduced, the pressure difference is increased, the vibration response frequency is higher, and the sound is larger.
