Detailed Description

In order to enable those skilled in the art to better understand the present utility model, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

As shown in fig. 1-3, a low water level alarm housing comprises a hollow housing 10, characterized in that: the shell 10 is connected with the end cover 11 through threads, the top of the end cover 11 is provided with the groove 14, the end cover 11 is positioned in the groove 14, the handle 15 is further fixed, the end cover 11 can be conveniently installed and detached through the handle 15, meanwhile, the whole device is also conveniently taken, the bottom of the groove 14 is provided with a plurality of hollow holes, each hollow hole is provided with a vibration sheet 16, the vibration sheet 16 is arranged in a protruding mode and protrudes towards the direction far away from the shell 10, the vibration sheet 16 is made of a metal material, through the arrangement of the vibration sheet 16, sound vibration can be amplified through the vibration sheet 16, the sound of an alarm can be more clearly transmitted to the outside, the periphery side of the end cover 11 is also provided with a plurality of water vents 20, each water vent 20 is communicated with the bottom of the groove 14, residual liquid in the groove 14 can be discharged through the water vents 20, the vibration sheet 16 is prevented from vibrating, the vibration sheet 16 cannot generate vibration, and accordingly sound cannot be transmitted, and a trigger component is further arranged in the shell 10;

the trigger assembly comprises a slide bar 12 penetrating through the bottom of the shell 10, a bottom plate 13 is fixed on the end face of one side, far away from the shell 10, of the slide bar 12, at least two mounting holes are formed in the bottom plate 13, a mounting table 18 is fixed on the end face of one side, located in the shell 10, of the slide bar 12, a spring is fixed between the mounting table 18 and the inner wall of the bottom of the shell 10, an alarm 17 is detachably mounted on the mounting table 18, a lantern ring 19 is fixed at the bottom of the shell 10, the lantern ring 19 is sleeved on the slide bar 12, the spring is located on the outer peripheral side of the lantern ring 19, resin paint is arranged on the side, close to the mounting table 18, of the lantern ring 19, and the alarm 17 can be completely isolated from water vapor by mounting the alarm 17 in the shell 10, so that the alarm 17 is prevented from being aged more quickly due to more water vapor, and the service life of the alarm 17 is greatly prolonged.

When the alarm 17 is used, the alarm 17 is mounted on the mounting table 18, then the bottom plate 13 is fixed in the water storage tank through the bolts, the end cover 11 is screwed up, when the water storage tank starts to be filled with water, the shell 10 starts to generate buoyancy along with the gradual rise of the water level, the shell 10 moves away from the bottom plate 13 under the action of the buoyancy, the mounting table 18 compresses the spring to drive the alarm 17 to be away from the end cover 11, the mounting table 18 can squeeze the lantern ring 19 along with the gradual increase of the buoyancy, so that the overall tightness of the shell is further increased, the situation that the interior of the shell 10 is wet due to the liquid entering the shell 10 is effectively avoided, and the alarm 17 is aged rapidly is caused.

When the water level of the water storage tank is too low, the buoyancy of the shell 10 is reduced, the shell 10 moves towards the direction close to the bottom plate 13 under the action of the thrust of the spring, the end cover 11 completely exposes out of the water surface, water in the groove 14 flows out through the water drain port 20, no liquid remains on the vibration plate 16 to block vibration of the vibration plate, then the shell 10 continues to move, when a starting button on the alarm 17 is abutted to the inner wall of the end cover 11, the alarm 17 is started to generate alarm sound, the sound clearly transmits the sound to the outside through the vibration generated by the vibration plate 16, the current water level is prompted to be too low, if the staff adds water inwards, the starting button on the alarm 17 is separated from contact with the end cover 11 under the action of the buoyancy, the alarm sound can be ended, and the next water level is conveniently and alarm is carried out too low.
