Description

Technical Field

[0001] This utility model relates to the field of infrared temperature measurement technology, specifically to an infrared thermometer with a multi-directional conversion detection head. Background Technology

[0002] An infrared thermometer is a device used to measure the surface temperature of an object. It utilizes the principle of infrared radiation to determine the object's temperature by detecting the infrared radiation energy emitted by the object. An infrared thermometer typically consists of an infrared sensor, an optical lens, and a thermometer. When infrared light passes through the lens and enters the instrument, it is captured by the sensor. The sensor converts the infrared radiation energy into an electrical signal and calculates the object's surface temperature based on the signal's intensity and frequency. To use an infrared thermometer, simply point the instrument at the target object and observe the temperature reading on the display screen to determine the object's surface temperature. It allows for rapid, non-contact temperature measurement of target objects and is suitable for various fields, such as industrial production, medical and health, and building maintenance. Chinese Patent No. CN202421376435.1 discloses an infrared thermometer, relating to the field of thermometer technology, including a thermometer body. A fixing block is fixedly connected to the bottom of the thermometer body near one end. A U-shaped component is fitted onto the bottom of the fixing block, with a disc passing through and rotatably connected to both ends of the U-shaped component via bearings. The discs are fixedly connected to the fixing block, and a handle is fixedly connected to the bottom of the U-shaped component. When not in use, the movable part can be pushed by hand to disengage the locking rod from the U-shaped part, thus retracting the handle and facilitating the storage of the thermometer. When in use, the movable part can be pushed by hand to insert the locking rod into the groove. After resetting the handle, the spring pushes the movable part, which moves and resets the locking rod, thus positioning the handle and preventing it from shaking during use.

[0003] Based on the above, the inventors have discovered the following problems: While the aforementioned device design improves the storage convenience of the thermometer, it does not address the core application pain point of infrared thermometers in multi-angle scanning measurements. Current mainstream infrared thermometers rely on manual handheld operation for fixed-point scanning, which faces significant limitations in intensive temperature measurement scenarios (such as mass temperature screening): operators need to frequently adjust their posture to adapt to objects at different heights and angles, leading to a surge in operational intensity. Prolonged operation easily causes operator fatigue and wastes human resources, reducing temperature measurement efficiency and sustainability. Utility Model Content

[0004] The purpose of this invention is to provide an infrared thermometer with a multi-directional switching detection head to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an infrared thermometer with a multi-directional conversion detection head, comprising a detection head and a support base. The detection head has an optical lens at its front end and an infrared detector inside. The photosensitive surface of the infrared detector receives infrared radiation converged by the optical lens. The infrared detector is connected by a wire, and the detection head has a connecting shaft at its rear end. The connecting shaft connects to an adjustment assembly, which is located on the upper end of the support base. A signal processor is located inside the support base, and the wire passes through the detection head and the support base and is electrically connected to the signal processor. The signal processor is electrically connected to a display screen, which is fixed to the support base.

[0006] Furthermore, the adjustment assembly includes a mounting base, a pair of support blocks, and a rotating shaft; the pair of support blocks are symmetrically fixed to one side of the upper end of the support base, and the two ends of the rotating shaft are rotatably mounted on the support blocks; one end of the rotating shaft is connected to a second motor, and a rotating component is fixedly mounted in the middle section of the rotating shaft; the mounting base is fixed on the support base and located above the rotating shaft; a first motor is mounted on the upper end of the mounting base, and the output shaft of the first motor passes downward through the mounting base and is fixedly connected to a limiting frame.

[0007] Furthermore, the rotating component has a horizontally opened guide groove on its side, and a sliding component is movably arranged in the guide groove. The sliding component is adapted to the guide groove, and the connecting shaft passes through the limiting frame and extends into the guide groove to be fixedly connected to the sliding component.

[0008] Furthermore, the limiting frame is arc-shaped, and the center of its arc coincides with the rotation center axis of the rotating component.

[0009] Furthermore, the cross-sectional dimension of the connecting shaft is smaller than the width of the guide groove.

[0010] Furthermore, the length direction of the guide groove is parallel to the axis of rotation.

[0011] Furthermore, the probe head is equipped with a dustproof lens.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the infrared thermometer with a multi-directional conversion detection head is reasonable and has the following advantages:

[0013] (1) The rotating shaft driven by the motor drives the rotating parts to rotate synchronously. The rotational motion is converted into the vertical pitch motion of the probe head with the rotating shaft as the fulcrum by the precise cooperation of the guide groove and the sliding part, so as to realize the automatic height adaptation function of the probe head. This mechanical transmission design replaces the traditional manual pitch posture adjustment operation, which significantly reduces the risk of back muscle strain caused by long-term operation of the operator; its wide pitch angle range can cover the detection needs from low-level targets to high-level targets. The operator does not need to repeatedly squat or stand up or tiptoe to operate, which fundamentally eliminates the problem of decreased detection efficiency and missed detection caused by postural fatigue, and greatly improves the sustainability and humanization level of public health monitoring.

[0014] (2) When the arc-shaped limiting frame is rotated by the motor, the probe head performs a horizontal rotational scan around the center of the rotating part. This mechanism breaks through the field-of-view limitations of traditional handheld devices, achieving an ultra-wide horizontal coverage range. A single-point deployment can complete the lateral detection of a channel-like scene. The dual-motor independent control mechanism ensures complete decoupling of horizontal and pitch movements, avoids interference from compound motion trajectories, ensures a constant distance between the optical lens and the target being measured, and maintains the stability of the radiation energy acquisition path, significantly extending the service life of the equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The present invention provides a technical solution as follows:

[0022] Example:

[0023] An infrared thermometer with a multi-directional switching detection head includes a detection head 1 and a support base 2. The detection head 1 has an optical lens 6 at its front end and an infrared detector 7 inside. The photosensitive surface of the infrared detector 7 receives infrared radiation converged by the optical lens 6. The infrared detector 7 is connected to a wire 3, and the detection head 1 has a connecting shaft 14 at its rear end. The connecting shaft 14 is connected to an adjustment assembly, which is located on the upper end of the support base 2. The support base 2 contains a signal processor 5, and the wire 3 passes through the detection head 1 and the support base 2 and is electrically connected to the signal processor 5. The signal processor 5 is electrically connected to a display screen 4, which is fixed to the support base 2.

[0024] The infrared radiation emitted by the target being measured is filtered by the dustproof lens to remove environmental impurities, and then focused by the optical lens 6 and accurately projected onto the photosensitive surface of the infrared detector 7. The infrared detector 7 converts the received light signal into an electrical signal, which is transmitted to the signal processor 5 inside the support base 2 through the wire 3. After being processed by temperature drift compensation and radiation and temperature linearization algorithms, an accurate temperature value is generated and finally displayed in real time on the display screen 4.

[0025] The adjustment assembly includes a mounting base 8, a pair of support blocks 9, and a rotating shaft 17. The pair of support blocks 9 are symmetrically fixed to one side of the upper end of the support base 2, and the two ends of the rotating shaft 17 are rotatably mounted on the support blocks 9. One end of the rotating shaft 17 is connected to a second motor 12, and a rotating component 13 is fixedly mounted in the middle section of the rotating shaft 17. The mounting base 8 is fixed on the support base 2 and located above the rotating shaft 17. A first motor 10 is mounted on the upper end of the mounting base 8, and the output shaft of the first motor 10 passes downward through the mounting base 8 and is fixedly connected to a limiting frame 11.

[0026] The rotating component 13 has a horizontally opened guide groove 15 on its side, and a sliding component 16 is movably arranged in the guide groove 15. The sliding component 16 is adapted to the guide groove 15, and the connecting shaft 14 passes through the limiting frame 11 and extends into the guide groove 15 to be fixedly connected to the sliding component 16.

[0027] The limiting frame 11 is arc-shaped, and the center of its arc coincides with the rotation center axis of the rotating component 13.

[0028] The cross-sectional dimension of the connecting shaft 14 is smaller than the width of the guide groove 15.

[0029] The length direction of the guide groove 15 is parallel to the axis of the rotation shaft 17.

[0030] The probe head 1 is equipped with a dustproof lens.

[0031] Working Principle: In use, this device drives the rotating shaft 17 to rotate via motor 2 (12), which in turn drives the rotating component 13 fixed on the shaft to rotate synchronously. Through the cooperation of the guide groove 15 and the sliding component 16, the rotational motion is converted into the pitch angle adjustment of the probe head 1, which swings vertically with the rotating shaft 17 as the fulcrum, enabling rapid adaptation to targets at different heights and eliminating fatigue from manual pitch operation. Simultaneously, motor 10 drives the limiting frame 11 to rotate around the output shaft. The design of its arc center coinciding with the rotation center of the rotating component 13 forces the connecting shaft 14 to slide horizontally within the guide groove 15, driving the probe head 1 to perform horizontal rotational scanning, significantly improving the efficiency of temperature measurement in dense crowds. This device achieves rapid spatial pose adjustment of the probe head 1 through a dual-degree-of-freedom electromechanical system, solving the technical pain point of difficulty in continuously covering targets at multiple angles during manual operation, significantly improving the efficiency and user-friendliness of dense temperature measurement scenarios. The gap design, where the cross-sectional dimension of the connecting shaft 14 is smaller than the width of the guide groove 15, effectively absorbs assembly tolerances, ensuring smooth movement and long-term reliability.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
