Technical Field
[0001] This utility model relates to the field of forehead thermometers, and in particular to a forehead thermometer with adjustable range. Background Technology
[0002] Forehead thermometers are widely used in medical, transportation, and public health fields. They have significant advantages in temperature measurement, measuring the temperature of the forehead area using infrared technology without direct skin contact. They can accurately measure the body temperature within seconds and display the results intuitively. Forehead thermometers usually have an optimal measurement distance, but in actual use, due to the lack of measurement, the thermometer head can only be placed at an approximate location by feeling. If the probe is too close, the reading may be too high; conversely, if it is too far away, insufficient signal will be received, further increasing the measurement error. Summary of the Invention

Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 - Figure 3 As shown, a range-adjustable forehead thermometer includes a drive chamber housing 1, a battery plug-in handle 2, a forehead temperature detection end 3, and a distance detector 5. The battery plug-in handle 2 is installed at the bottom of the drive chamber housing 1, and the distance detector 5 is located on the forehead temperature detection end 3 and moves together with it to change the detection distance. The front side of the drive cavity housing 1 is provided with a drive cavity 15, and a distance adjustment motor 17 is provided in the drive cavity 15. The distance adjustment motor 17 is connected to a lead screw 24 through a transmission seat 16. The end of the lead screw 24 is threadedly connected to a lead screw thread sleeve 25. The end of the lead screw thread sleeve 25 is connected to the forehead temperature detection end 3. The drive cavity housing 1 is also connected to the forehead temperature detection end 3 through a limiting rod assembly to facilitate limiting the movement of the forehead temperature detection end 3. The drive cavity 15 is equipped with a control motherboard 22, which is connected to the forehead temperature detection end 3, the distance detector 5, and the distance adjustment motor 17.
[0017] like Figure 1 - Figure 3 As shown, this utility model also discloses the following more optimized specific structures: The limiting rod assembly includes a limiting hole frame 18 and a limiting rod 19. The rod body of the limiting rod 19 is inserted into the limiting hole of the limiting hole frame 18. One end of the limiting rod 19 is equipped with a rod stop 20, and the other end of the limiting rod 19 is connected to the forehead temperature detection end 3. The limiting hole frame 18 is fixed to the groove wall of the drive cavity groove 15.
[0018] The transmission base 16 includes a transmission base housing 28. Inside the transmission base housing 28, there are meshing lead screw gear 26 and motor gear 27. The motor gear 27 is mounted on the motor shaft of the distance adjusting motor 17. One end of the lead screw 24 extends into the transmission base housing 28 and is connected to the lead screw gear 26.
[0019] The back wall of the drive cavity 15 is provided with heat dissipation holes, and heat dissipation mesh 23 is installed in the heat dissipation holes.
[0020] The distance adjustment motor 17 is fixed in the drive cavity slot 15 by the motor frame 21.
[0021] The plug-in battery 6 includes a battery body 12, a buckle base 11 is installed at the bottom of the battery body 12, a press-type buckle 14 is provided on the buckle base 11, a battery electrode 13 is provided on the battery body 12, and a battery slot is provided at the bottom of the battery plug-in handle 2. The inner side of the battery slot is provided with a connecting spring and a buckle groove. The press-type buckle 14 is engaged in the buckle groove, and the connecting spring is pressed onto the battery electrode 13. The connecting spring and the buckle groove are the commonly used matching structures of existing plug-in batteries, which will not be described in detail here.
[0022] A start button 7 is provided on the outside of the battery plug handle 2, and a limit rod 19 is provided on the outside of the drive cavity shell 1.
[0023] A corrugated connecting sleeve 4 is connected between the drive cavity housing 1 and the forehead temperature detection end 3, which is used to protect the internal drive components.

[0025] like Figure 1 - Figure 3 The adjustable forehead thermometer shown is set with the optimal detection distance at the factory. However, in actual use, the detection distance cannot be accurately determined, and it can only be placed in an approximate position, resulting in some deviation in detection accuracy. In the above structure, after the start button 7 is turned on, the distance adjustment motor 17 drives the lead screw 24 to rotate and provides feedback on the distance through the distance detector 5.
