[0039] Example 1

[0040] like Figure 2-9As shown, the utility model provides an automatic start-stop fan device, including a fan 1, the fan 1 is sleeved with a mounting frame 2, the fan 1 is connected to a ground terminal 4 through a ground wire 3, an electrode at one end of the fan 1 is connected to a temperature control component 5 fixed on the outside of the fan 1, and an electrode at the other end of the fan 1 is connected to a second power line 7, the temperature control component 5 is connected to an electric plug 6, and the electric plug 6 is connected to the second power line 7;

[0041] The temperature control assembly 5 includes a temperature control box body 501 connected to the fan 1, and a temperature control cover 510 is detachably connected to the opening of the temperature control box body 501. The temperature control cover 510 is provided with two sets of sensing ports 511. The sensing ports 511 are detachably connected to a protective mesh cover 512. A first U-shaped electrical connector 506 and a second U-shaped electrical connector 508 are connected to the temperature control box body 501 through a bayonet connecting rod 502. One end of the first U-shaped electrical connector 506 is connected to the second U-shaped electrical connector 508 through a set of temperature control switches 507. 08, the other end of the first U-shaped electrical connector 506 is connected to the other end of the second U-shaped electrical connector 508 through another group of temperature control switches 507, the two groups of temperature control switches 507 correspond to the two groups of sensing ports 511 one by one and are movably plugged in, the first U-shaped electrical connector 506 is connected to the electric plug 6 through an extended power cord 513 running through the temperature control box body 501, and the second U-shaped electrical connector 508 is connected to one end electrode of the fan 1 through a first power cord 509 running through the temperature control box body 501.

[0042] How it works

[0043] When in use, the electric plug 6 is connected to the power socket to complete the external power supply access, the negative pole of the fan 1 is directly connected to the negative pole of the power supply through the second power line 7, and the positive pole of the fan 1 is connected to the positive pole of the power supply through the first power line 509, two parallel temperature control switches 507, and the extension power line 513. The normally open and normally closed state of the temperature control switch 507 can be selected, and the temperature control parameters can be selected. For example, the ambient temperature in the entire control box is required to be no higher than 40°C, and the optional parameter of the temperature control switch 507 is normally open when it is lower than 40°C, that is: when the ambient temperature is lower than 40°C, the temperature control switch 507 is in the normally open state, the entire fan 1 power supply circuit is in the open circuit state, and the fan 1 does not start; when the ambient temperature is higher than 40°C, the temperature control switch 507 is in the closed state, the entire fan 1 power supply circuit becomes the open circuit state, and the fan 1 starts; after the fan 1 dissipates heat and the ambient temperature drops below 40°C, the temperature control switch 507 is disconnected again, and the fan 1 stops. The two temperature control switches 507 are connected in parallel to prevent the other temperature control switch 507 from still ensuring the normal operation of the circuit when one of the temperature control switches 507 fails.

[0044] When replacing the temperature control switch 507, ensure that the electric plug 6 is separated from the power socket, remove the temperature control cover 510, remove and replace the temperature control switch 507 from the U-shaped electrical connector; when performing routine maintenance on the temperature control switch 507, remove the protective mesh cover 512 and clean the protective mesh cover 512; when repairing the fan 1, separate the temperature control box body 501, and at the same time separate the first power cord 509 from the second U-shaped electrical connector 508, and separate the extended power cord 513 from the first U-shaped electrical connector 506, so that the fan 1 and the temperature control component 5 can be separated, which is convenient for the fan 1 to complete independent maintenance or supply the temperature control component 5 to other fans 1 for use.
