Technical Field
[0001] The utility model belongs to the technical field of constant temperature control, and in particular relates to an unmanned constant temperature control system. Background Art
[0002] Electric blankets are very common heating tools in households. However, when people use them, especially at night, the excessive heating power of electric blankets will cause the temperature in the room to rise over time, reducing people's living comfort. Once turned off, the temperature will cool down quickly, and it is inconvenient to manually control the heating time. Therefore, an unmanned constant temperature control system is needed to solve the above problems. Utility Model Content
[0003] The purpose of the utility model is to provide an unmanned constant temperature control system to solve the problems raised in the above background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an unmanned constant temperature control system, comprising a power supply, an electromagnetic relay and an electric contact thermometer, wherein a first wire is connected to one side of the power supply, and the top end of the first wire is connected to the same electromagnetic relay; a second wire is connected to the other side of the electromagnetic relay, and the top end of the second wire is connected to the electric contact thermometer.
[0005] By setting up the above structure, the system can automatically adjust the temperature of the electric blanket at night, ensuring that people do not have to wake up frequently due to temperature problems, ensuring the quality of sleep at night, and can realize unmanned automatic temperature control. The temperature error of the system is controlled within 0.1 degrees Celsius, ensuring the control accuracy of the system.
[0006] As a preferred implementation manner, the power supply is arranged below the electromagnetic relay, and the power supply and the electromagnetic relay are arranged on one side of the electric contact thermometer.
[0007] By setting a power supply and an electromagnetic relay, the electromagnetic relay is connected to the electric blanket through an external cable, and the power supply can supply power to the electric blanket through the electromagnetic relay.
[0008] As a preferred embodiment, the electric contact thermometer is composed of two wires connected to the upper end, metal at the lower end, a glass tube in the middle, two glass columns filled with mercury, and electrodes between the glass columns and the metal.
[0009] By setting up an electric contact thermometer, because it is internally provided with a wire, a metal, two glass columns filled with mercury and an electrode, the electric contact thermometer can conduct temperature well.
[0010] As a preferred implementation, the electromagnetic relay is composed of an armature, a spring, a moving contact, and a static contact.
[0011] By setting up an electromagnetic relay, the electromagnetic relay can use electromagnetic force to attract or release the armature, thereby realizing circuit opening and closing.
[0012] As a preferred implementation, the electromagnetic relay is configured as a normally closed type.
[0013] By setting the electromagnetic relay, since the electromagnetic relay is set to be normally closed, when the electromagnetic relay is not energized, the electromagnetic relay is in a closed state, and when the electromagnetic relay is energized, the electromagnetic relay is disconnected.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] The utility model is provided with a power supply, an electromagnetic relay, an electric contact thermometer, a first wire and a second wire. When the temperature of the working electric blanket rises to a preset temperature, the electric contact thermometer is connected, at which time the electromagnetic relay is powered on and disconnected, and the electric blanket stops heating. When the temperature of the electric blanket decreases, the electric contact thermometer is disconnected, at which time the electromagnetic relay is powered off, and the electric blanket continues to heat. The system can automatically adjust the temperature of the electric blanket at night, ensuring that people do not need to wake up frequently due to temperature problems, ensuring the quality of sleep at night, and realizing unmanned automatic temperature control. The temperature error of the system is controlled within 0.1 degrees Celsius, ensuring the control accuracy of the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described below in conjunction with embodiments.
[0020] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0021] See also Figure 1-2The utility model provides an unmanned constant temperature control system, including a power supply 1, an electromagnetic relay 2 and an electric contact thermometer 3. A first wire 4 is connected to one side of the power supply 1, and the top of the first wire 4 is connected to the same electromagnetic relay 2. A second wire 5 is connected to the other side of the electromagnetic relay 2, and the top of the second wire 5 is connected to the electric contact thermometer 3. The power supply 1 is arranged below the electromagnetic relay 2, and the power supply 1 and the electromagnetic relay 2 are arranged on one side of the electric contact thermometer 3. By arranging the power supply 1 and the electromagnetic relay 2, the electromagnetic relay 2 is connected to the electric blanket through an external cable, and the power supply 1 can supply power to the electric blanket through the electromagnetic relay 2. The electric contact thermometer 3 is connected to two wires from the upper end. The electric contact thermometer 3 is composed of a wire, a metal at the lower end, a glass tube in the middle, two glass columns filled with mercury and electrodes between the glass columns and the metal. Because it is equipped with a wire, a metal, two glass columns filled with mercury and electrodes, the electric contact thermometer 3 can conduct temperature well. The electromagnetic relay 2 is composed of an armature, a spring, a moving contact and a static contact. By setting the electromagnetic relay 2, the electromagnetic relay 2 can use electromagnetic force to attract or release the armature, thereby realizing the opening and closing of the circuit. The electromagnetic relay 2 is set to a normally closed type. Because the electromagnetic relay 2 is set to a normally closed type, when the electromagnetic relay 2 is not powered on, the electromagnetic relay 2 is in a closed state, and when the electromagnetic relay 2 is powered on, the electromagnetic relay 2 is disconnected.
[0022] The working principle and use process of the utility model are as follows: the electromagnetic relay 2 is connected to the electric blanket through an external cable. When the power supply 1 supplies power to the external electric blanket through the electromagnetic relay 2 and the temperature of the working electric blanket rises to a preset temperature, the electric contact thermometer 3 is connected. At this time, the electromagnetic relay 2 is powered on and off, and the electric blanket stops heating. When the temperature of the electric blanket drops, the electric contact thermometer 3 is disconnected. At this time, the electromagnetic relay 2 is powered off, and the electric blanket continues to heat.
