Abstract
The utility model discloses a water temperature reduction prompt device. The device comprises a spring switch, an alarm, a protective resistor A, a protective resistor B, a temperature sensing resistor, a power supply, a switch, a permanent magnet, an electromagnet B and an electromagnet A. The device belongs to the technical field of electromagnetism. In the usage process, the switch and the permanent magnet are manually separated, and a switch in the general line is closed to switch on the master power supply in the general line. As the water temperature reduces, the resistance of the temperature sensing resistor decreases, and then the current in the general line increases. When the water temperature reduces to the prescribed range, the electromagnet A in a branch line II absorbs the spring in a branch line I under the effects of a certain current to allow the spring switch to be closed, so as to switch on the alarm that can rings out to prompt people. Then people can cut off the switch manually to allow the permanent magnet to absorb the spring sheet of the switch to cancel the alarm. If people fail to timely cut off the switch, when the water temperature reduces to a certain range, the electromagnet B can absorb the spring sheet of the switch in the general line, so as to cut off the switch to cancel the alarm.
Description
Technical field
The utility model belongs to electromagnetics technical field, is specifically related to a kind of water temperature and reduces suggestion device.
Background technology
Water is Source of life, and a lot of situations in life make us to water temperature, have certain requirement, and as the water in relevant vessel in the water in water, swimming pool in bath, laboratory, one glass of reeky water has been forgotten in time and drunk sometimes, may need to be outwelled.
Summary of the invention
The purpose of this utility model is to provide a kind of a kind of device that can automatic alarm when the water temperature in vessel drops to a certain degree.
The utility model comprises: three circuit that branch road in parallel, power supply, switch, thermo-sensitive resistor are connected.Wherein branch road I is in series by snap switch, alarm; Branch road II is in series by electromagnet A, protective resistance A; Branch road III is in series by electromagnet B, protective resistance B.Snap switch in branch road I is open in usual above electromagnet A, and the below of electromagnet B is the switch in main line, a permanent magnet side by side on the limit of electromagnet B.When using this device, manually that switch is separation with permanent magnet, closed main line switch, connects main line power supply, along with the decline of water temperature, the resistance of thermo-sensitive resistor diminishes, and in main line, electric current increases, when water temperature drops to specialized range, electromagnet A in branch road II is under certain function of current, under snap switch in branch road I is inhaled, make snap switch closure, alarm just sounds to point out people.Now manually cut-off switch of people, makes permanent magnet hold the shell fragment of switch, cancels and reporting to the police.If people do not have cut-off switch timely, when water temperature drops to certain limit, electromagnet B just can under certain function of current, pick up main line in the shell fragment of switch, disconnected switch, cancelled warning, and now the shell fragment of switch is held by permanent magnet when picking up at electromagnet B just now.Therefore the water of certain water temperature is used or protects in the invention timely for prompting people, reduces the wasting of resources, has positive meaning.
Accompanying drawing explanation
As shown in Figure 1, for a kind of water temperature, reduce the circuit structure diagram of suggestion device.
Wherein: 1-snap switch, 2-alarm, 3-protective resistance A, 4-protective resistance B, 5-thermo-sensitive resistor, 6-power supply, 7-switch, 8-permanent magnet, 9-electromagnet B, 10-electromagnet A.
Embodiment
Below in conjunction with accompanying drawing, a kind of water temperature of the utility model is reduced to suggestion device and be described further.
As shown in Figure 1, a kind of water temperature reduces suggestion device, comprises snap switch 1, alarm 2, protective resistance A3, protective resistance B4, thermo-sensitive resistor 5, power supply 6, switch 7, permanent magnet 8, electromagnet B9, electromagnet A10.
Before not using this device, switch 7 is open in usual, and the shell fragment of switch 7 is held by permanent magnet 8, and the snap switch 1 in branch road I is open in usual.While using this device, manually that the shell fragment of switch 7 is separation with permanent magnet 8, make switch 7 closures, now power supply has been connected on main line, along with the decline of water temperature, the resistance of thermo-sensitive resistor 5 diminishes, and in main line, electric current increases, when water temperature drops to specialized range, electromagnet A in branch road II is under certain function of current, under snap switch in branch road I 1 is inhaled, make snap switch 1 closure, alarm 2 just sounds to point out people.Now manually cut-off switch 7 of people, makes permanent magnet 8 hold the shell fragment of switch 7, cancels and reporting to the police.If people do not have cut-off switch 7 timely, when water temperature drops to certain limit, electromagnet B just can under certain function of current, pick up main line in the shell fragment of switch 7, disconnected switch 7, cancelled warning, and now the shell fragment of switch 7 is held by permanent magnet 8 when picking up at electromagnet B just now.
