Referring to Figures 1-3, in order to achieve the preferred embodiment of the present invention, a fluid negative pressure sound control monitoring device is provided, which first depends on the pressure demand of the user (fluid, air pressure) and the line pressure. The fluid pressure monitoring device comprises: a fluid unit 10, a negative pressure mixing unit 20, an acoustic sensing unit 30, a starting unit 40, a power unit 50 and a receiving unit. 60;

The fluid unit 10 is used to generate a fluid (eg, water flow, air flow);

The negative pressure mixing unit 20 is connected to the fluid unit 10 and the ozone generator 30 by a connecting pipe 200; wherein the negative pressure mixing unit 20 has a water inlet 21, a first-class channel 22, a water outlet 23, and a negative pressure inlet 24, the water inlet 21 is connected to the connecting pipe 200 of the fluid unit 10, and the negative pressure inlet 24 is connected to the connecting pipe 200 of the sound sensing unit 30, and the flow channel 22 is gradually narrowed toward the middle. The water inlet 21 and the water outlet 23 form a diverging structure to form an approximate venturi structure. Therefore, when the fluid (ie, water flow) enters the inside of the negative pressure mixing unit 20 from the water inlet 21 and flows out from the water outlet 23, the process will occur. A negative pressure is formed in the flow channel 22 (ie, below atmospheric pressure);

The sound sensing unit 30 is connected to the negative pressure mixing unit 20 in a telecommunication manner. When the negative pressure mixing unit 20 generates a negative pressure, the sound sensing unit 31 senses the sound wave flowing inside the connecting tube 200 and emits a sound wave. Sound signal (which may be a voltage or current signal) to the starting unit 40;

In this embodiment, the sound sensing unit 30 can be a microphone sensor, also known as a dynamic pressure sensor, which is a transducer that converts sound into a voltage or current signal. The pressure gradient caused by the sound causes the internal diaphragm of the microphone to be deformed, and the deformation is converted into a voltage or current signal by using different energy conversion technologies, and the microphone can be classified into a moving coil microphone or a condenser microphone according to the internal structure;

The activation unit 40 is in telecommunication connection with the power unit 50, and receives the power generation of the power unit 50, and the activation unit 40 is in an open state in a normal state, and only receives the sound signal of the sound sensing unit 30.

In this embodiment, the first display element and the second display element of the display unit 70 may be a light-emitting diode (LED).

The fluid unit 10 of the present invention can be designed as a faucet or a shower head. The faucet is described below as a preferred embodiment, and the drawings used therein are only for the purpose of illustration and auxiliary instructions, and may not be used after the implementation of the new model. The true proportion and precise configuration, so the scope of the attached schema and the configuration relationship should not be interpreted and limited to the scope of the actual implementation of the new model.

The user firstly connects the power unit 50 to the activation unit 40 to cause the activation unit 40 to actuate and form an open state under normal conditions, and the first display element is activated to generate a light source for the user to know; When it is opened, the fluid unit 10 generates a water flow (i.e., a fluid). When water flows into the negative pressure mixing unit 20 through the connecting pipe 200, the flow path 22 of the negative pressure mixing unit 20 is formed by the structure of the venturi. The pressure difference effect causes the negative pressure mixing unit 20 to generate a negative pressure. When the sound sensing unit 30 senses the sound wave flowing inside the connecting tube 200, an acoustic signal is sent to the starting unit 40, so that the original state is in an open state. The activation unit 40 is in an on state, and the second display element is activated to generate a light source for the user to know, and the activation unit 40 sends an activation signal to the receiving unit 60 when receiving the on-state of the sound sensing unit 30.

It is worth mentioning that the present invention mainly uses the activation unit 40 to be telecommunicationly connected between the sound sensing unit 30 and the receiving unit 60. The sound sensing unit 30 is not directly connected to the receiving unit 60, so when the sound sensing unit When the sound wave of the air flowing inside the connecting tube 200 is sensed, the starting unit 40 is triggered first, and then the receiving unit 40 is triggered by the starting unit 40, and since the starting unit 40 is in an open state under normal conditions, only receiving When the sound signal of the sound sensing unit 30 is reached, the conductive state is formed and an activation signal is sent to the receiving unit 60; in other words, the starting unit 40 is in an open state before the sound signal of the sound sensing unit 30 is received. At this time, the starting unit 40 cannot trigger the receiving unit 60 (ozone generator) to generate ozone to achieve the goal of facilitating efficient use of ozone.

Therefore, the present invention uses the starting unit 40 as a relay component between the sound sensing unit 30 and the receiving unit 60, and the starting unit 40 is activated by the power supply of the power unit 50, that is, in use. After the activation unit 40 is first connected to the power unit 50, the activation unit 40 can effectively receive the sound signal (which can be a voltage or current signal) of the sound sensing unit 30 and generate an activation signal to the receiving unit 60.
