Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
The utility model provides an alarm device that can nondestructive monitoring liquid level in food processing, includes alarm main part 13, capacitive sensing probe, transmission line, liquid level pipe 16, alarm main part 13 passes through transmission line connection capacitive sensing probe, capacitive sensing probe fixes on the pipe wall of liquid level pipe 16, alarm main part 13 includes control circuit device, epitheca 17, inferior valve 18, epitheca 17 is connected with inferior valve 18, and inside fixed control circuit device, control circuit device includes PCB circuit board 10, and is equipped with power module 1, control module 2, boost module 3, relay module 4, epitheca plug seat 5, inferior valve plug seat 6, general plug seat 7 that charges, switch 8, buzzer 9 on PCB circuit board 10, the epitheca 17 surface is equipped with the honeycomb through-hole, and the honeycomb through-hole just sets up to buzzer 9 positions, capacitive sensing probe includes high-level capacitive sensing probe 11, low-level capacitive sensing probe 12, high-level capacitive sensing probe 11, low-level capacitive sensing probe 12 respectively through fixing the upper and lower position of pipe wall at liquid level pipe 16, and the pipe wall of ribbon respectively, and the transmission line connection high-level sensing probe 11, low-level line connection general plug seat 6, high-level sensing probe 11, low-level line connection general plug seat 14, transmission line connection high-level sensing probe 15.
The power supply module 1 supplies power for the whole equipment, the power supply module 1 has the functions of low-voltage protection, charging, power management, overcurrent protection and reverse connection prevention, when the switch 8 is shifted to an open gear, the indicator light on the power supply module 1 is turned on, the power supply module 1 starts to supply power for the control module 2, the boosting module 3 and the relay module 4, the indicator light of the control module 2 is turned on, and the control module 2 starts to enter the running cycle.
The control module 2 is connected with the high-level capacitance type sensing probe 11 through the upper probe plug-in seat 5 and the high-level transmission line 14 and is used for monitoring the liquid level top dead center in the liquid level pipe 16; the lower probe plug seat 6 and the low-level transmission line 15 are used for monitoring the liquid level bottom dead center in the liquid level pipe 16 together with the low-level capacitance type sensing probe 12.
When the control module 2 starts to enter the operation cycle, the state of the capacitive sensing probe is first acquired once. When the capacitive sensing probe does not sense liquid, the system is in a standby mode. When the capacitive sensing probe senses liquid, an indicator lamp on the capacitive sensing probe can be lightened, and meanwhile, the capacitive sensing probe enters an operation mode, and the state of the capacitive sensing probe is obtained once.
When the capacitive sensing probe senses liquid, the indication lamp on the capacitive sensing probe can be lightened, and the control module 2 sends out intermittent instructions to the relay module 4, the relay module 4 intermittently conducts the circuits of the boosting module 3 and the buzzer 9, so that the buzzer 9 sends out intermittent beeping sounds, and the indication lamp on the relay module 4 can intermittently flash along with the instructions.

When the capacitive sensing probe senses liquid, the control module 2 stops sending instructions to the relay module 4, the buzzer 9 stops ringing, the indicator light on the relay module 4 is extinguished, and the control module 2 is turned to acquire the state of the capacitive sensing probe, so that the control module can cycle reciprocally.
The high-level capacitance type sensing probe 11 and the low-level capacitance type sensing probe 12 are respectively arranged at the upper dead point and the lower dead point of the required liquid level.

When the low-level capacitance type sensing probe 12 does not sense liquid, namely, the liquid level is proved to be lower than the bottom dead center of the pipe wall of the liquid level pipe 16, if the liquid level is pumped out continuously, the pump idles, the pump body is burnt out, and the alarm main body 13 sounds long at the moment; when the low-level capacitive sensing probe 12 senses liquid and the high-level capacitive sensing probe 11 does not sense liquid, the liquid level is proved to be low and low, and the alarm main body 13 does not sound; when the high-order capacitance type induction probe 11 senses liquid, the liquid level is too high, if the liquid level is fed into the tank continuously, the tank overflows, and then the alarm main body 13 sounds intermittently.
