Description

Technical Field

[0002] With the emergence of COVID-19 in recent years, temperatures have become increasingly important in places like shopping malls, hospitals, and factories, allowing for the isolation of those with high fevers and suspected infection. Infrared temperature guns collect infrared radiation emitted by the human body and convert it internally, typically taking 1-2 seconds to measure body temperature. However, the distance between the temperature gun and the person being measured can affect test accuracy. Currently, the most popular temperature guns on the market utilize a cylindrical pyroelectric detector to collect infrared radiation from the human body. This type of gun cannot detect distance, resulting in errors in temperature measurements. Utility Model Content

[0019] Reference numerals:

[0020] Detection unit 10, lens assembly 11, signal processor 12, concentric circle infrared transmitter and receiver 13, front gun housing 14, mounting unit 20, display screen 21, handle 30, temperature measurement button 31, power module 32, and limiting rib 33. DETAILED DESCRIPTION

[0021] In order to facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0022] This application proposes an electronic body temperature gun, please refer to Figure 1, including: a detection part 10, a mounting part 20 and a handle part 30, and the mounting part 20 is connected between the detection part 10 and the handle part 30.

[0023] The mounting portion 20 is provided with a display screen 21 for displaying the calculated temperature value. The handle portion 30 is provided with a temperature measurement button 31 for turning on the electronic thermometer.

[0024] The detection unit 10 includes a lens assembly 11, a signal processor 12, a concentric infrared transmitter and receiver 13, and a front gun housing 14. The signal processor 12 is used to receive and process the data collected by the concentric infrared transmitter and receiver 13.

[0025] Specifically, the concentric infrared transmitter-receiver 13 is positioned outside the front housing, while the signal processor 12 and lens assembly 11 are positioned inside. The concentric infrared transmitter-receiver 13 and display screen 21 are electrically connected to the signal processor 12. A signal port is defined in the center of the front housing 14. The concentric infrared transmitter-receiver 13 transmits a series of concentric infrared rays. By detecting the radius of the concentric infrared circles and the intensity of the infrared rays, the electronic thermometer detects the distance between the test subject and the test subject. The signal processor 12 then calculates and obtains temperature data based on this information. The signal processor then provides corresponding correction data during temperature data processing, automatically compensating for the error and accurately measuring the subject's temperature, thereby improving the accuracy of the electronic thermometer's measurement.

[0026] Among them, the functions of the lens assembly 11 are: first, to focus and refract the pyroelectric infrared signal onto the concentric infrared transmitter and receiver 13; second, to divide the detection area into several bright areas and dark areas, so that the moving objects entering the detection area can produce changes in the form of temperature on the concentric infrared transmitter and receiver 13 to release infrared signals, and then transmit the signals to the signal processor 12.

[0027] Operational process: The staff member or user points the electronic thermometer at the human head and presses the temperature measurement button 31 to start the electronic thermometer and measure the temperature. The concentric circle transmitter and receiver transmit and receive concentric circle signals to calculate the distance to the object being measured. Simultaneously, the infrared light emitted by the object passes through the optical lens, generating an infrared signal. Finally, the signal processor 12 combines the two to calculate the temperature of the object being measured, and the measured temperature value is displayed on the display 21.

[0028] In one embodiment, a power module 32 and a circuit module are also disposed within the handheld housing. The power module 32 is located within the lower interior of the handle 30 and provides power to the electronic thermometer. The circuit module is located within the mounting portion 20 and connects the signal processor 12 with the concentric infrared transmitter and receiver 13, the display screen 21, and other components to achieve temperature measurement.

[0029] Furthermore, when the power module 32 is charging, it is very likely to generate high temperatures inside the power module 32, which can easily damage the display screen 21, signal processor 12, and lens assembly 11. Heat dissipation efficiency is low in an electronic thermometer. Therefore, the handle 30 is provided with heat dissipation holes at the power module 32 to dissipate heat from within the electronic thermometer, thereby extending the service life of the electronic thermometer.

[0030] Please refer again Figure 1 Limiting ribs 33 extend from the upper and lower ends of the power module 32 inside the handle portion 30 , respectively. The limiting ribs 33 limit and hold the power module 32 to prevent the power module 32 from being inside the handle portion 30 .

[0031] In one embodiment, a hanging ring is provided on the outer side of the mounting portion 20 . The hanging ring is in a circular ring shape and passes through the mounting portion 20 .

[0032] Furthermore, an indicator light is provided on the outside of the mounting portion 20. When the human body temperature is at an abnormal temperature, the indicator light turns yellow at a low temperature, turns red at a high temperature, and turns white at a normal temperature, so that the status of the body temperature measurement can be observed intuitively, making the use of the electronic thermometer more simplified.

[0033] In one embodiment, a wireless charging base is provided below the handle 30 to enable wireless charging of the electronic thermometer. When the electronic thermometer needs to be charged, it can be charged by simply placing it in the wireless charging area, reducing the need for charging cables and improving the neatness of the electronic thermometer.

[0034] Furthermore, the upper portion of the handle portion 30 is detachably connected to the mounting portion 20 , so that the electronic thermometer is easy to disassemble and maintain for deep disinfection.

[0035] Preferably, the handle portion 30 is provided with an ergonomic portion that conforms to the fingers, so that when the user holds the handle portion 30, the ergonomic portion fits the five fingers, thereby improving the comfort of holding the hand.

[0036] In addition, the detection part 10 also includes a protective cover. When the electronic thermometer is not in use, the protective cover is placed on the outside of the front gun housing 14 to prevent the detection part 10 from being damaged and contaminated, thereby ensuring the cleanliness of the electronic thermometer.

[0037] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
