Example 1

A waterproof buzzer, in order to solve the problem that many electronic components are installed inside the buzzer, rainwater enters the inside when the buzzer is used in rainy days or outdoors, which is easy to damage internal parts due to short circuit, and reduces the service life, and the buzzer is not provided with a perfect drainage system inside, as shown in figure 1, figure 2, figure 3 and figure 4, as a preferred embodiment, the waterproof buzzer comprises a shell body 1, the shell body 1 comprises a buzzer 4 and a base 2 arranged at the bottom of the shell body 1, wherein the model of the buzzer 4 is HYD-4218, a water-stop sheet 11 is arranged inside the shell body 1, a waterproof film with the model of CY-150 is adhered on the outer surface of the water-stop sheet 11, thereby achieving the purpose of water stopping, a cavity 13 is formed between the water-stop sheet 11 and the shell body 1, a plurality of drainage boxes 21 are arranged around the outer wall of the base 2, the front ends of the drainage boxes 21 are provided with water outlet holes 212, a sliding block 217 is connected in a sliding manner inside the water outlet hole 212, a spring 211 is arranged at the rear end of the sliding block 217, a fixed block 214 is arranged at the end part, far away from the sliding block 217, of the spring 211, a baffle plate 213 is arranged at the front end of the fixed block 214, communicating grooves 216 are arranged on both sides of the fixed block 214, a water inlet hole 215 is arranged at the rear end of the water discharge tank 21, rainwater in the base 2 flows into the water discharge tank 21 through the water inlet hole 215, then the rainwater flows to the front end of the fixed block 214 through the communicating grooves 216, the sliding block 217 is accumulated and pressed by the gravity of the rainwater, the sliding block 217 slides along the inner wall of the water outlet hole 212 in the direction far away from the fixed block 214 under the action of pressure, then a gap is formed between the sliding block 217 and the baffle plate 213, the rainwater enters the water outlet hole 212 through the gap, the rainwater is discharged out of the base 2 through the water outlet hole 212, then the sliding block 217 is reset by the spring 211 generated by deformation after the rainwater is drained so as to be used next time, when external rainwater enters the water outlet hole 212, baffle 213 plays the hindrance effect to sliding block 217 to reach the purpose of one-way drainage, shell body 1 top is equipped with conical cover 12, and conical cover 12 plays waterproof effect to shell body 1 top.

In addition, the circuit, the electronic component and the module in the invention are all the prior art, and the technical personnel in the field can completely realize the protection without needless remark, and the protection content of the invention also does not relate to the improvement of the internal structure and the method.

In this example, a plurality of through-hole 15 has been seted up at shell body 1 outer wall top, and the sound that bee calling organ 4 sent propagates to the external world through-hole 15, avoids shell body 1 to cause the influence to sound propagation.

Furthermore, the bottom of the cone cover 12 is provided with a fixing wall 121, the top of the housing body 1 is provided with a thread 14, the fixing wall 121 is screwed with the thread 14, when in installation, a user rotates the cone cover 12, then the fixing wall 121 is subject to the screwing force generated by the thread 14 to separate the fixing wall 121 from the housing body 1, and when in disassembly, the cone cover 12 is rotated reversely, so that the purpose of facilitating the disassembly and the assembly of the cone cover 12 is achieved.

Specifically, buzzer 4 sets up inside cavity 13, buzzer 4 outside is equipped with fixing base 3, T type groove 31 has been seted up to 3 inner wall intermediate positions of fixing base, 4 outer wall intermediate positions of buzzer are equipped with T type strip 42, T type strip 42 and the cooperation of T type groove 31 joint, during installation buzzer 4, the staff arranges T type strip 42 one end in with T type groove 31 looks vertically position, then insert T type strip 42 in T type groove 31 to reach the purpose fixed to buzzer 4.

In addition, the top of the buzzer 4 is provided with a groove 41, the top of the groove 41 is provided with a portable block 411, and the portable block 411 is convenient for a worker to hold, so that the purpose of convenient carrying is achieved.

Further, a sealing ring 22 is arranged at the connecting position of the top surface of the base 2 and the shell body 1, the type of the sealing ring 22 is AS-568, and the sealing ring 22 prevents rainwater from permeating into the base 2.

When the rain-proof water-proof rain cap is used, firstly, when the conical cap 12 is installed, a user rotates the conical cap 12, then the fixing wall 121 is subjected to the screwing force generated by the threads 14 to enable the fixing wall 121 to be separated from the shell body 1, the conical cap 12 plays a role in water prevention for the top of the shell body 1, and then rain water slides off from the surface of the conical cap 12 under the action of gravity to avoid water accumulation.

When rainwater seeps into the shell body 1, the rainwater firstly flows into the cavity 13, the rainwater in the cavity 13 flows into the base 2 under the action of gravity, the rainwater in the base 2 flows into the drainage box 21 through the water inlet hole 215, then the rainwater flows to the front end of the fixed block 214 through the communicating groove 216, the gravity of the rainwater accumulates and presses the sliding block 217, the sliding block 217 slides along the inner wall of the water outlet hole 212 under the action of pressure in the direction far away from the fixed block 214, then a gap is formed between the sliding block 217 and the baffle plate 213, the rainwater enters the water outlet hole 212 through the gap, the rainwater is discharged out of the base 2 through the water outlet hole 212, then the spring 211 resets the sliding block 217 through the elasticity generated by deformation after the rainwater is drained, so that the sliding block 217 can be used next time, when the external rainwater enters the water outlet hole 212, the baffle plate 213 can block the sliding block 217, and therefore the purpose of unidirectional drainage is achieved.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
