[0002] Infrared forehead thermometer, also known as forehead temperature gun, infrared thermometer, is used to measure human body temperature. The measurement principle of infrared forehead thermometer is: any object above absolute zero (-273℃) will emit infrared rays, and the infrared forehead thermometer receives infrared rays through the sensor to obtain temperature data.
[0003] like Figure 1 As shown, a temperature measuring button 12 is provided on the handle 11 of the infrared forehead thermometer 1. The method of using the infrared forehead thermometer 1 is as follows: the area above the bridge of the nose and between the two eyes is the radiation source closest to the normal body temperature. The infrared forehead thermometer 1 is placed 5-6 cm away from this area, and the temperature can be measured by pressing the temperature measuring button 12.
[0004] Since the user cannot ensure that the temperature measurement distance is 5-6cm when using an infrared forehead thermometer, if the temperature measurement distance is too far or too close, it will affect the infrared forehead thermometer's ability to perceive infrared rays, thereby reducing the accuracy of temperature measurement.

[0053] In the first embodiment, the driving structure includes a gear 25 , a rack 25 , an operating rod 27 , an elastic member 28 , and a fixing rod 29 .
[0054] like Figure 7 As shown, the gear 25 is welded and fixed to the end of the rotating shaft 23.
[0055] like Figure 7As shown, the rack 25 is disposed below the gear 25 , the rack 25 meshes with the gear 25 , the rack 25 is provided with a slide groove 261 , the side wall of the bottom plate 21 is welded and fixed with a slide rail 211 , and the slide rail 211 and the slide groove 261 are horizontally slidably matched.
[0056] like Figure 6 As shown, the top end of the operating rod 27 is welded and fixed to the side wall of the rack 25, and the bottom end of the operating rod 27 extends downward.
[0057] like Figure 6 As shown, the top end of the fixing rod 29 is fixed to the side wall of the bottom plate 21 by welding.
[0058] like Figure 6 As shown, the elastic member 28 is a spring, one end of the spring is connected to the operating rod 27, and the other end of the spring is connected to the fixing rod 29.
[0059] When using the thermometer of this embodiment 1:
[0060] (1) See Figure 4 to Figure 5 The user overcomes the elastic force of the elastic member 28 and presses the operating rod 27 to the right. The operating rod 27 drives the rack 25 to move to the right. The gear 25 meshing with the rack 25 rotates counterclockwise. The gear 25 drives the shaft 23 to rotate counterclockwise. The shaft 23 drives the distance limiting rod 24 to rotate counterclockwise. Figure 5 In the state shown, the distance L between the end of the distance limiting rod 24 away from the rotating shaft 23 and the left side of the infrared forehead thermometer 1 is 5-6 cm.
[0061] (2) The user keeps the distance rod 24 in Figure 5 In the state shown, the end of the distance limiting rod 24 away from the rotating shaft 23 is placed against the forehead of the person being measured, and the temperature measurement button 12 is pressed to measure the body temperature.
[0062] (3) The user releases the pressure on the operating rod 27, and the operating rod 27 moves to the left under the elastic force of the elastic member 28, and the operating rod 27 drives the rack 25 to move to the left, and the gear 25 drives the distance limiting rod 24 to rotate clockwise through the rotating shaft 23, so that the distance limiting rod 24 returns to the position as shown in FIG. Figure 4 Status shown.
[0063] It can be known from the above usage process that in the thermometer of this embodiment 1, when the end of the distance limiting rod 24 away from the rotating shaft 23 is rotated to a state of protruding from the left side of the infrared forehead thermometer 1, the end of the distance limiting rod 24 away from the rotating shaft 23 can be placed on the forehead of the person being measured, and the temperature measurement distance can be maintained by using the distance limiting rod 24 to improve the temperature measurement accuracy.
[0064] In the thermometer of the first embodiment, if the distance limiting rod 24 is kept flat on the bottom plate 21, Figure 4As shown, the entire thermometer has a compact structure and is easy to store.
[0065] In the thermometer of this embodiment 1, since only the bottom plate 21 in the distance limiting mechanism 2 is directly connected to the infrared forehead thermometer 1, the distance limiting mechanism 2 can be temporarily installed on the existing infrared forehead thermometer 1 without modifying the structure of the existing infrared forehead thermometer 1, which is convenient to use.
[0066] Further, such as Figure 6 As shown, a guide rod 271 is welded and fixed in the middle of the operating rod 27, and a guide hole (not shown in the figure) is provided at the bottom of the fixing rod 29. The guide rod 271 is horizontally slidably matched with the guide hole, and the spring sleeve serving as the elastic member 28 is arranged on the guide rod 271.
[0067] By providing the guide rod 271 and the guide hole and sleeve the spring on the guide rod 271, the spring can change along the axial direction of the guide rod 271 when the spring is deformed, so that the spring can be elastically deformed along its own axial direction, preventing the spring from deviating from the axial direction and deforming.

[0069] The stop block 272 is provided to prevent the guide rod 271 from slipping out of the guide hole on the fixing rod 29 , thereby improving the reliability of the sliding fit between the guide rod 271 and the guide hole.
[0070] Further, such as Figure 6 As shown, a receiving box 212 is welded and fixed to the top surface of the bottom plate 21, and a wiping hole 2121 is provided on the side of the receiving box 212 close to the distance limiting rod 24. A sterilizing cotton 213 is provided in the receiving box 212, and the sterilizing cotton 213 is exposed from the wiping hole 2121. One end of the distance limiting rod 24 away from the rotating shaft 23 can abut against the part of the sterilizing cotton 213 exposed from the wiping hole 2121.
[0071] By providing the accommodating box 212 and the disinfecting cotton 213, when the distance rod 24 is in a state of being horizontally placed above the bottom plate 21, the end of the distance rod 24 away from the rotating shaft 23 can be in contact with the disinfecting cotton 213, and the end of the distance rod 24 away from the rotating shaft 23 can be disinfected by the disinfecting cotton 213, so that when the thermometer is used later, the disinfected end of the distance rod 24 can be placed against the forehead of the person being measured, thereby reducing the risk of cross infection and improving the safety of use.
[0072] Embodiment 2:
[0073] This embodiment 2 provides another solution for the driving structure. Fig.11 As shown, in this embodiment 2, the driving structure includes a driving motor 210 , a chassis of the driving motor 210 is welded and fixed to the side wall of the bottom plate 21 , and an output end of the driving motor 210 is welded and fixed to the rotating shaft 23 .
[0074] When the driving motor 210 drives the rotating shaft 23 to rotate counterclockwise, the rotating shaft 23 drives the distance limiting rod 24 to rotate counterclockwise, so that the end of the distance limiting rod 24 away from the rotating shaft 23 rotates to a state protruding from the left side of the infrared forehead thermometer 1. At this time, the end of the distance limiting rod 24 away from the rotating shaft 23 can be placed against the forehead of the person being measured to maintain the temperature measurement distance.
[0075] When the driving motor 210 drives the rotating shaft 23 to rotate clockwise, the rotating shaft 23 drives the limiting rod 24 to rotate clockwise, so that the limiting rod 24 returns to the state of being horizontally placed above the bottom plate 21 .
[0076] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
