[0002] The black ball thermometer and hygrometer (also known as the WBGT index meter) is a professional device used to comprehensively evaluate the thermal environment. It can comprehensively reflect the thermal load of air temperature, humidity and radiant heat on the human body.

[0003] In outdoor operations, warehouse management, and industrial sites, black sphere thermometers and hygrometers need to monitor both ambient temperature and humidity and radiation temperature (black sphere temperature) simultaneously. Currently, in practical use, traditional equipment is often left open when the ambient temperature and humidity are being measured. When the thermometer is in standby mode or in abnormal environments (such as rainy days or dusty environments), dust and rainwater can easily enter and damage the internal sensor, affecting the subsequent detection accuracy and lifespan of the black sphere thermometer and hygrometer. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a black ball thermometer and hygrometer.

The top of the thermometer body is provided with a detection column and a black sphere from bottom to top. The black sphere and the detection column respectively house a temperature sensor and a temperature and humidity sensor. The detection column is a cylindrical structure with several strip-shaped through holes symmetrically opened on its outer wall. The isolation ring is sleeved on the outer end of the detection column and can rotate horizontally relative to the detection column. The isolation ring has through holes corresponding to the strip-shaped through holes. When the isolation ring rotates 90° counterclockwise, the holes are misaligned with the strip-shaped through holes, and the isolation ring covers the strip-shaped through holes.

[0006] In a preferred embodiment, a glass ball screw is embedded in the inner wall of the isolation ring, and a groove is formed inwardly on the outer wall of the detection column to fit and engage with the glass ball screw. The groove is located within the running trajectory of the glass ball screw.

[0007] In a preferred embodiment, the card slot is generally arc-shaped, there are two card slots, and the two are arranged at a 90° angle, one of the card slots is arranged on the same axis as the strip-shaped through hole.

[0008] In a preferred embodiment, an elastic hook is provided on the back of the thermometer body, and a rope threading hole is also provided on the elastic hook.

[0009] In a preferred embodiment, the bottom of the thermometer and hygrometer body is a flat structure, and a threaded hole is provided at the center of the bottom of the thermometer and hygrometer body.

[0010] In a preferred embodiment, a PCB motherboard is housed inside the thermometer body, and both the temperature sensor and the temperature and humidity sensor are electrically connected to the PCB motherboard.

[0037] A black sphere thermometer and hygrometer, reference Figure 1-8 The device includes a thermometer and hygrometer body 200 and an isolation ring 100. The top of the thermometer and hygrometer body 200 is provided with a detection column 210 and a black ball 220 from bottom to top. The black ball 220 and the detection column 210 respectively house a temperature sensor and a temperature and humidity sensor 400. The detection column 210 has a cylindrical structure and several strip-shaped through holes 211 are symmetrically opened on its outer wall. The isolation ring 100 is sleeved on the outer end of the detection column 210 and can rotate horizontally relative to the detection column 210. The isolation ring 100 has holes 110 that correspond to the strip-shaped through holes 211. When the isolation ring 100 rotates 90° counterclockwise, the holes 110 and the strip-shaped through holes 211 are misaligned, and the isolation ring 100 covers the strip-shaped through holes 211.

[0038] Please refer to the technical solution adopted in this utility model. Figure 7 and Figure 8 As shown, a rotatable isolation ring 100 is fitted onto the detection column 210. When a detection operation is required, the isolation ring 100 can be rotated to align the strip-shaped through hole 211 with the hole position 110. At this time, the strip-shaped through hole 211 is in a state of communication with the external environment, and normal temperature and humidity acquisition operations can be performed. When in standby mode or in case of severe weather, it can be quickly rotated 90° to misalign the strip-shaped through hole 211 with the hole position 110, thereby achieving physical sealing of the strip-shaped through hole 211. This can protect the internal sensor and improve the detection accuracy and service life of the subsequent black ball thermometer and hygrometer.

[0039] In this embodiment, please refer to Figures 3-5 As shown, a glass ball screw 120 is embedded in the inner wall of the isolation ring 100, and a groove 212 is formed inwardly on the outer wall of the detection column 210 to fit and engage with the glass ball screw 120. The groove 212 is located within the running trajectory of the glass ball screw 120. The groove 212 has an arc-shaped structure, and there are two grooves 212, which are set at a 90° angle. One of the grooves 212 is set on the same axis as the strip-shaped through hole 211. The glass ball screw is set in cooperation with the two sets of grooves 212, and a clear locking sensation is generated when rotating, ensuring that the isolation ring 100 can accurately stop at the "fully open" or "fully closed" position, which can realize the precise closing and opening operation of the strip-shaped through hole 211.

[0040] In this embodiment, an elastic hook 230 is provided on the back of the thermometer and hygrometer body 200. The elastic hook 230 is also provided with a rope hole. The thermometer and hygrometer body 200 can be hung by the elastic hook 230, such as on a shelf. At the same time, the rope hole can also be connected to a rope to carry it by hand or tie it.

[0041] In this embodiment, please refer to Figure 6 As shown, the bottom of the thermometer and hygrometer body 200 is a flat structure, and a threaded hole 240 is also provided in the center of the bottom of the thermometer and hygrometer body 200. The flat bottom structure plus the threaded hole in the center can be adapted to be placed on a desktop and fixed with a tripod, so as to achieve stable monitoring on the desktop and the ground (i.e., mounted on a tripod and placed on the ground).

[0042] In this embodiment, the thermometer and hygrometer body 200 houses a PCB motherboard 500. Temperature and humidity sensors 400 are electrically connected to the PCB motherboard 500. The front face of the thermometer and hygrometer body 200 is equipped with a display screen 300 and an audible and visual alarm light 700, both electrically connected to the PCB motherboard 500. The side of the thermometer and hygrometer body 200 also has operation buttons 800. The back of the thermometer and hygrometer body 200 has a battery compartment 600 containing a battery pack electrically connected to the PCB motherboard 500. The temperature sensor and humidity sensor 400 detect the temperature on the black sphere and the ambient temperature, respectively. When the temperature reaches the user-set temperature, the PCB motherboard 500 controls the audible and visual alarm light 700 to activate, simultaneously triggering an audible and visual alarm to alert the user that the current temperature exceeds the set range.
