Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in fig. 1 and 2, the waterproof barometer that this embodiment provided, including cup 5, waterproof cap 2 and driving motor 8, waterproof cap 2 is hollow structure, and the outer lane sets up sealing

washer

3, and 2 inner chambers of waterproof cap set up

baroceptor

1, and 2 bottoms of waterproof cap set up roof 6 through threaded connection, and 6 bottoms of roof connect with cavity telescopic link 7, and cavity telescopic link 7 is driven by driving motor 8.

The top of the cup body 5 is flanged outwards, a sealing ring II 4 is arranged at the flanging position, and a through hole is formed in the bottom of the cup. The bottom of the driving motor 8 is provided with a waterproof connector 11, the outer ring of the waterproof connector 11 is provided with threads, the outer ring of the threads is provided with a third sealing ring 9, the third sealing ring penetrates through a through hole in the bottom of the cup body, and the third sealing ring is fixed to the bottom of the cup body through a nut 10 outside the cup body.

The signal wire of the air pressure sensor 1 passes through the top plate 6, the middle part of the hollow telescopic rod 7 and the driving motor 8 and is communicated with other device equipment through a waterproof connector 11. The driving motor 8 obtains power supply and control signals from other devices through a waterproof connector 11.

The working principle is as follows:

the utility model discloses a when waterproof barometer need get into waterproof state, cavity telescopic link 7 contracts under driving motor 8 effect, drives waterproof cap 2 through roof 6 and covers on cup 5 downwards, and at this moment, sealing washer one 3 and sealing washer two 4 are in between the turn-ups of cup 5 and waterproof cap 2, play the sealing effect, make cup inner chamber and external isolated, and at this moment, waterproof barometer no longer detects the atmospheric pressure value.

When the utility model discloses a waterproof barometer need detect atmospheric pressure, when no longer waterproof, cavity telescopic link 7 stretches out under driving motor 8 effects, drive waterproof cap 2 through roof 6 and upwards leave cup 5, at this moment, sealing washer one 3 and cup 5, two 4 and the separation of waterproof cap 2 of sealing washer, no longer play sealing effect, the air passes through the clearance between waterproof cap and the cup inner wall, the trompil department from the roof gets into the inner chamber of waterproof cap 2, contact with baroceptor 1, thereby can detect the atmospheric pressure value, and communicate with other device through waterproof connector 11.
