Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of temperature control, in particular to an overtemperature protector. Background Art
[0002] Overtemperature alarm facilities are required in fields such as home, electronics, machinery, and medical treatment, so as to warn users to dispose of the overtemperature situation in time through the overtemperature alarm facilities and avoid overtemperature safety accidents. Existing overtemperature alarm facilities generally include a temperature control switch, a power supply, and an acoustic-optic warning facility. When in use, the temperature-sensitive surface of the temperature control switch is closely attached to the object to be detected. When an overtemperature situation occurs, the temperature control switch acts, and the acoustic-optic warning facility works to give an acoustic-optic warning. Since such overtemperature alarm facilities need to connect in series multiple facilities such as a power supply and an acoustic-optic warning, they are very inconvenient to use and are easily interfered by the multiple facilities connected in series such as a power supply and an acoustic-optic warning, so that the temperature-sensitive surface of the temperature control switch cannot be closely attached to the object to be detected, thus affecting the normal performance of the overtemperature protection function. Summary of the Invention
[0003] The purpose of the present invention is to provide an overtemperature protector that can overcome one or more of the above-mentioned drawbacks, is convenient to use, and can easily ensure that the temperature-sensitive surface continuously and stably adheres to the object to be detected.
[0004] The present invention is realized as follows: it includes a temperature-sensitive cylinder, a temperature control switch, a power switch, a power supply, a buzzer, a warning light, a fixing plate, and a cover plate. The bottom of the temperature-sensitive cylinder is the temperature-sensitive surface, and the top of the temperature-sensitive cylinder is an open mouth. The temperature control switch, the power switch, the power supply, the buzzer, and the warning light are arranged inside the temperature-sensitive cylinder. The temperature-sensitive surface of the temperature control switch is closely attached to the bottom surface of the bottom of the temperature-sensitive cylinder. The power switch, the power supply, the buzzer, and the warning light are arranged on the side of the temperature control switch. The fixing plate is located above the temperature control switch, the power switch, the power supply, the buzzer, and the warning light. The cover plate covers the open mouth at the top of the temperature-sensitive cylinder. The switch contact of the power switch passes through the fixing plate and the cover plate in sequence, and the warning light of the warning light penetrates through the fixing plate and the cover plate.
[0005] When in use, the bottom of the temperature-sensitive cylinder of the overtemperature protector of the present invention is closely attached to the object to be detected, the power switch is pressed, and the warning light lights up. When the temperature exceeds the set temperature, it is transmitted to the temperature-sensitive surface of the temperature control switch through the temperature-sensitive surface at the bottom of the temperature-sensitive cylinder. The temperature control switch acts to start the buzzer to give an alarm. At the same time, the warning light can be controlled to flash for warning.
[0006] Since a temperature-sensitive cylinder is adopted, and the temperature control switch, the power switch, the power supply, the buzzer, and the warning light are arranged inside the temperature-sensitive cylinder, there is no interference from externally connected multiple facilities, ensuring that the temperature-sensitive surface continuously and stably adheres to the object to be detected, and it is also convenient to use.
[0007] Preferably, the temperature control switch adopts a thermostat of a thermosensitive bimetallic sheet.
[0008] Compared with the prior art, the present invention has the advantages of being convenient to use and easily ensuring that the temperature-sensing surface continuously and stably adheres to the object to be detected. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION
[0011] The overtemperature protector of the present invention will be further described in detail below in conjunction with the drawings and embodiments: As Figure 1 , 2 shown, the overtemperature protector of the present invention is implemented as follows. It includes a temperature-sensing cylinder 1, a temperature control switch 2, a power switch 3, a power supply 4, a buzzer 5, a warning light 6, a fixing plate 7, and a cover plate 8. The temperature-sensing cylinder 1 is a circular cylinder made of aluminum alloy. The bottom 101 of the temperature-sensing cylinder 1 is the temperature-sensing surface, and the top 102 of the temperature-sensing cylinder 1 is an open mouth. The temperature control switch 2, the power switch 3, the power supply 4, the buzzer 5, and the warning light 6 are arranged inside the temperature-sensing cylinder 1. The power supply 4 is a control circuit with a battery and a power supply circuit. The temperature-sensing surface 201 of the temperature control switch 2 closely adheres to the bottom surface of the bottom 101 of the temperature-sensing cylinder 1. The power switch 3, the power supply 4, the buzzer 5, and the warning light 6 are arranged on the side of the temperature control switch 2. The fixing plate 7 is located above the temperature control switch 2, the power switch 3, the power supply 4, the buzzer 5, and the warning light 6. The cover plate 8 covers the open mouth of the top 102 of the temperature-sensing cylinder 1. The switch contact 301 of the power switch 3 passes through the fixing plate 7 and the cover plate 8 in sequence, and the warning light of the warning light 6 penetrates through the fixing plate 7 and the cover plate 8.
[0012] As Figure 3 shown, after the buzzer 5 and the warning light 6 are connected in parallel, they are connected in series with the temperature control switch 2 and the power switch 3 and then connected to the power supply 4; Or, as Figure 4 shown, after the buzzer 5 is connected in series with the temperature control switch 2, it is connected in parallel with the warning light 6, and then connected in series with the power switch 3 and then connected to the power supply 4; Alternatively, as Figure 5 shown, the power supply supplies power to the buzzer 5 and the warning light 6 through the controller 9 (such as including an MCU and a switch circuit controlled by the MCU, the MCU controls the opening and closing of the switch circuit, and the switch circuit controls the buzzer 5 and the warning light 6 to work), and the temperature control switch 2 and the power switch 3 are connected to the electrical signal input end of the controller 9.
[0013] In use, the bottom 101 of the temperature sensing cylinder 1 of the overtemperature protector of the present invention is closely attached to the object to be detected. When the power switch 3 is pressed and the circuit of Embodiment 4 is adopted, the warning light 6 lights up to indicate that the device is in working state. When the temperature exceeds the set temperature, it is transmitted to the temperature sensing surface 201 of the temperature control switch 2 through the temperature sensing surface of the bottom 101 of the temperature sensing cylinder 1. The temperature control switch 2 acts, and the power supply 4 supplies power to the buzzer 5 to start the buzzer 5 to alarm. If the circuit of Embodiment 3 is adopted, the warning light 6 changes from off to flashing warning.
[0014] When the circuit of Embodiment 5 is adopted, the power switch 3 is closed to send a control signal to the controller 9, and the warning light 6 is always on to indicate that the device is in working state. When the temperature exceeds the set temperature, it is transmitted to the temperature sensing surface 201 of the temperature control switch 2 through the temperature sensing surface of the bottom 101 of the temperature sensing cylinder 1. The temperature control switch 2 acts to send a control signal to the controller 9, and the controller 9 controls the buzzer 5 to start alarming. At the same time, it controls the warning light 6 to change from always on to flashing warning.
