Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1: Please refer to Figure 1-5A temperature controller based on a wireless sensor network comprises a housing 1, six groups of temperature monitoring probes 2 for monitoring the external air temperature are installed inside the housing 1, a control unit 5 is arranged at one end of the three groups of temperature monitoring probes 2, two groups of control units 5 are arranged to control the temperature monitoring probes 2 to monitor in turn, thereby increasing the service life of the temperature monitoring probes 2, an adjustment structure 3 for controlling the power supply of the temperature monitoring probes 2 is arranged between the two groups of temperature monitoring probes 2, and a dehumidification structure 4 for helping to dehumidify the inside of the device is arranged in the inner cavity of the housing 1;

[0026] See also Figure 2-5 The adjusting structure 3 includes two groups of connecting plates 301. One end of the two groups of connecting plates 301 close to the two groups of control units 5 is fixedly connected to them through springs. The outer wall of the spring is wrapped with an insulating sleeve. The side ends of the connecting plates 301 are connected to the power supply through cables. Pushing posts 302 are arranged between the connecting plates 301. The non-axial part of the pushing posts 302 is fixedly connected with a connecting shaft 303. When the connecting shaft 303 drives the pushing posts 302 to rotate, the pushing posts 302 can push one group of connecting plates 301 to approach the temperature monitoring probe 2. The two groups of connecting plates 301 are close to the two groups of control units. The top and bottom of the control unit 5 are respectively fixedly installed with power supply contacts 304, and the ends of the two groups of control units 5 close to the power supply contacts 304 are respectively installed with power connection contacts 305. When a group of connecting plates 301 approaches the control unit 5, so that a group of power supply contacts 304 and a group of power connection contacts 305 are attached to each other, the connecting plates 301 can supply power to the temperature monitoring probe 2 and the control unit 5 through the power supply contacts 304 and the power connection contacts 305, so that a group of control units 5 control the temperature monitoring probe 2 to monitor the external air temperature.

[0027] See also Figure 2-3 A baffle 306 is fixedly installed between the two groups of control units 5, and both ends of the connecting shaft 303 are movably connected to the inside of the baffle 306 through bearings. One end of the connecting shaft 303 passes through the baffle 306 and is fixedly connected to a rotating block 307. Four groups of blocking blocks 308 are fixedly arranged on the end of the baffle 306 close to the rotating block 307. An arc groove is opened inside the end of the rotating block 307 close to the blocking block 308, and the inside of the arc groove fits with the end of the blocking block 308 away from the baffle 306. When the rotating block 307 drives the connecting shaft 303 to rotate, when the arc groove rotates on the outer wall of the blocking block 308, the blocking block 308 can reduce the continuous rotation of the rotating block 307 due to inertia through friction with the arc groove, thereby helping the rotating block 307 to stop;

[0028] See also Figure 2-4 , a special-shaped block 309 is provided on the top of the rotating block 307, (for reference to be more intuitive Figure 4Two groups of special-shaped blocks 309 appear in the figure. The special-shaped block 309 is arranged at one end of the top of the rotating block 307, so that when the rotating block 307 falls downward, one end of the rotating block 307 is pushed to drive the connecting shaft 303 to rotate. A frame 310 is arranged on the top of the outer wall of the special-shaped block 309. The inner wall of the frame 310 fits at both ends of the outer wall of the special-shaped block 309. The end of the special-shaped block 309 away from the rotating block 307 is meshed with a threaded rod 311. When the threaded rod 311 rotates, it can drive the special-shaped block 309 to move upward. When the special-shaped block 309 moves up to the top and fits the bottom of the inner cavity of the frame 310, due to the shape of the frame 310, the special-shaped block 309 will be separated from the threaded rod 311 when it continues to move upward. When the special-shaped block 309 is separated from the support, it will fall rapidly. The first gear 313 is fixedly connected to the bottom of the threaded rod 311. The rotation of the first gear 313 can drive the threaded rod 311 to rotate. The first gear 313 is meshed with the second gear 314. The second gear 314 and the top of the first gear 313 are movably connected with a support plate 315 through a column shaft. The outer wall of the support plate 315 is fixedly connected to the inside of the housing 1, so as to support the first gear 313 and the top of the second gear 314. The bottom of the oblique push block 312 is fixedly connected to the top of the support plate 315. The end of the second gear 314 away from the first gear 313 is meshed with the third gear 316. When the third gear 316 rotates, it can drive the second gear 314 and the first gear 313 to rotate.

[0029] Example 2: Please refer to Figure 1-2 The outer wall of the shell 1 is provided with multiple groups of through grooves corresponding to the temperature monitoring probes 2. The outer wall of each group of temperature monitoring probes 2 is provided with a protective cover 6. One end of the multiple groups of protective covers 6 close to the shell 1 is snapped into the inside of the shell 1. The protective cover 6 can protect the outer wall of the temperature monitoring probe 2 when in use, thereby extending the service life of the temperature monitoring probe 2 and reducing the entry of external dust into the interior;

[0030] See also Figure 1 and 4 The dehumidification structure 4 includes a protection box 401, the top of which is fixedly installed on the bottom of the shell 1 by multiple sets of screws, and a motor 402 is installed in the inner cavity of the protection box 401. The protection box 401 can protect the outside of the motor 402 when in use. At the same time, because the motor 402 is arranged at the bottom of the shell 1, it can prevent the heat energy generated by the motor 402 during operation from accumulating inside the shell 1. The output shaft of the motor 402 is fixedly connected with a roller 403, and the roller 403 passes through the outer wall of the protection box 401 and is fixedly connected with a fan blade 404. By driving the motor 402 so that its output shaft drives the roller 403 and the fan blade 404 to rotate, the fan blade 404 can accelerate the air circulation inside the shell 1, thereby ventilating the inside of the shell 1, mixing the moisture inside with the dry air outside, and helping the internal dehumidification of the device, and the top of the roller 403 is fixedly connected to the bottom of the third gear 316;

[0031] See also Figure 1-2 A plurality of groups of special-shaped grooves are provided at the bottom of the shell 1, and the wind can flow into or out of the shell 1 through the special-shaped grooves. Four groups of arc plates 405 are fixedly connected to the top of the support plate 315, and the four groups of arc plates 405 are symmetrically distributed at the four corners inside the shell 1. A plurality of groups of strip grooves are provided inside the arc plates 405, and the air flow can flow into the shell 1 evenly through the arc plates 405 and the strip grooves, which helps to ventilate the corners inside the shell 1, thereby reducing moisture accumulation, thereby effectively reducing the moisture inside the temperature controller.

[0032] The working principle of the utility model is:

[0033] First, connect the cable at the side end of the connecting plate 301 to the power supply, and drive the motor 402 so that its output shaft drives the third gear 316 to rotate through the roller 403, and the third gear 316 drives the threaded rod 311 to rotate through the first gear 313. When the threaded rod 311 rotates, it can push the special-shaped block 309 to move upward. When it moves to its top and fits with the bottom of the frame 310, the frame 310 that continues to move upward can push the special-shaped block 309 to move toward the end of the rotating block 307 through the bottom shape, and after disengaging from the threaded rod 311, it pushes the rotating block 307 to rotate when moving downward. When the rotating block 307 rotates, it can drive the connecting shaft 303 and the push column 302 to rotate, so that the push column 302 pushes a group of connecting plates 301 to approach the control unit 5, so that a group of power supply contacts 304 and a group of power receiving contacts 305 are connected. When the connecting plate 301 is fitted together, the connecting plate 301 can power the temperature monitoring probe 2 and the control unit 5 through the power supply contact block 304 and the connecting contact block 305, so that a group of control units 5 control the temperature monitoring probe 2 to monitor the external air temperature, and the data monitored by the temperature monitoring probe 2 is transmitted to the control unit 5 through the wireless communication module, and after being processed by the control unit 5, the temperature controller adjusts the temperature through the temperature difference. At the same time, when the special-shaped block 309 moves down to the top of the oblique push block 312, the oblique push block 312 can help the special-shaped block 309 to re-engage with the threaded rod 311; in addition, when a group of control units 5 or temperature monitoring probes 2 are damaged and cannot be repaired in time, the motor 402 can be turned off to allow another group of intact control units 5 and temperature monitoring probes 2 to continue monitoring.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
