[0002] With the development of technology, infrared thermometers have become very popular. In the actual use process, although some are equipped with transparent infrared thermometer lenses for protection, the presence of dust and water vapor in the air is inevitable, which blocks the infrared rays, making it impossible to obtain the true temperature of the object and affecting the measurement accuracy. Especially outdoors, such as in sandy weather, the surface of the infrared thermometer lens will be covered with dust. In this case, the thermometer can basically not work properly. Therefore, it is necessary to clean the surface of the infrared temperature measuring device regularly.

[0025] To facilitate the understanding of this application, the following will describe this application more comprehensively with reference to the relevant attached drawings. Embodiments of this application are shown in the attached drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this application more thorough and comprehensive.

[0026] As Figures 1 to 4 shown, an infrared temperature measuring device with a self-cleaning function includes an angle adjusting member 6 and two outer shells 1, and an infrared temperature detector 2 is provided in each outer shell 1. The angle adjusting member 6 includes a protective shell 61 arranged between the two outer shells 1. A biaxial motor 63 is installed inside the protective shell 61, and the surfaces of the two outer shells 1 are respectively connected to the two output ends of the biaxial motor 63. By starting the biaxial motor 63, the two infrared temperature detectors 2 can be driven to rotate and adjust in the vertical direction for use.

[0027] A rotating seat 62 is fixedly installed at the bottom of the protective shell 61. An installation seat 64 is arranged at the bottom of the rotating seat 62. A servo motor is fixedly installed inside the installation seat 64, and the output end of the servo motor is connected to the bottom of the rotating seat 62. The rotating seat 62 is driven to rotate by the servo motor, so as to control the horizontal rotation of the two infrared temperature detectors 2.

[0028] A plurality of support columns 65 are fixedly installed at the top of the installation seat 64. A ball 66 is rotatably installed at the top of each of the plurality of support columns 65. An annular groove 621 for guiding the movement of the plurality of balls 66 is formed inside the rotating seat 62. When the rotating seat 62 rotates, the annular groove 621 inside it fits with the tops of the plurality of balls 66, and the plurality of balls 66 assist in supporting the rotating seat 62, making the rotation of the rotating seat 62 more stable.

[0029] Among them, the infrared temperature detector 2 is arranged near one end of the housing 1, and an air flow chamber 11 is formed between the infrared temperature detector 2 and the inner wall of the housing 1. A blowing component 3 is also arranged in each housing 1. The blowing component 3 includes a fan frame 31 and a fan 32. The fan frame 31 is fixed to the inner wall of the housing 1, and the fan 32 is installed on the fan frame 31. By operating the fan 32, blowing inside the housing 1 is realized. At the same time, a plurality of exhaust grooves 12 are formed in the inner wall of the housing 1. The exhaust grooves 12 are arranged on the periphery of the infrared temperature detector 2 and are spaced circumferentially around the housing 1. The exhaust grooves 12 communicate the inside of the housing 1 with the side of the infrared temperature detector 2 close to the outside. Thus, the air flow inhaled by the blowing component 3 can pass through the air flow chamber 11 and then be blown onto the surface of the infrared temperature detector 2 through the exhaust grooves 12, thereby realizing the cleaning of the dust on the surface of the infrared temperature detector 2.

[0030] A conical flow guide seat 5 is also fixed to the side of the fan frame 31 facing the infrared temperature detector 2. By blowing air into the housing 1 through the fan 32 to clean the dust on the surface of the infrared temperature detector 2, the conical flow guide seat 5 is provided to enable the air flow formed by the blowing component 3 to be more evenly guided into the air flow chamber 11, and then evenly blown onto the surface of the infrared temperature detector 2 from each exhaust groove 12 to achieve cleaning.

[0031] In addition, a filter component 4 is detachably arranged at one end of the housing 1 far from the infrared temperature detector 2. The filter component 4 includes a threaded installation cylinder 41, and a filter net plate 42 is fixed in the threaded installation cylinder 41. Thus, when the blowing component 3 sucks air into the housing 1, the external air can enter the inside of the housing 1 after being filtered by the filter net plate 42. A fitting cover 43 is also fixed on the threaded installation cylinder 41. A plurality of air holes 431 are formed in the fitting cover 43. The filter net plate 42 can be protected through the fitting cover 43, reducing the possibility of the filter net plate 42 being damaged. The air holes 431 are provided to enable the external air to smoothly enter the housing 1.

[0032] A plurality of modules are installed in the infrared temperature detector 2, and the plurality of modules work together to realize the infrared temperature measurement function and automatically detect whether cleaning is required, including an infrared temperature measurement module, an image recognition module, a cleaning module, a communication module, and a user interface module;

[0033] The infrared temperature measurement module includes an infrared camera and an image processing unit for infrared temperature measurement and image acquisition;

[0034] The image recognition module includes an image preprocessing unit and a cleanliness detection unit for preprocessing and analyzing the acquired images, judging the cleanliness of the lens of the infrared temperature detector 2, and sending a corresponding command signal if cleaning is required;

[0035] The cleaning module includes a cleaning instruction generation unit and a cleaning device, which are used to generate corresponding cleaning instructions according to the output signal of the image recognition module and control the activation of the cleaning device. Among them, the cleaning device is the air blowing assembly 3.

[0036] The communication module includes a wireless communication unit and a control signal receiving unit, which are used to achieve remote control and data transmission during the operation of the device.

[0037] The user interface module includes a remote monitoring center, which is used to provide remote and local monitoring and control interfaces to facilitate user operation.

[0038] When the infrared thermometer 2 is running, the infrared temperature measurement module collects image and temperature data and transmits these data to the image recognition module for preprocessing and analysis. The image recognition module preprocesses, enhances, and extracts features from the collected images. Based on the extracted features, it uses image recognition algorithms to analyze the cleanliness of the images, determine whether there is dirt or dust on the surface of the lens of the infrared thermometer 2, and whether the cleanliness meets the preset standard. If the standard is met, the cleaning stops; if not, the cleaning starts. If the cleanliness does not meet the standard, the cleaning module generates a cleaning instruction and starts the cleaning device to perform the cleaning operation. At the same time, the image recognition module is still detecting until the surface of the lens of the infrared thermometer 2 reaches the required cleaning standard, and the image recognition module issues a stop instruction.

[0039] After the cleaning is completed, the data is sent to the remote device through the communication module. The user interface module then displays the temperature measurement data and the device status on the remote monitoring center. Users can remotely monitor and issue instructions through the communication module to control the operation of the system.

[0040] The implementation principle of the infrared thermometer device with a self-cleaning function in this application is as follows: When it is detected that there is dust attached to the lens of the infrared thermometer 2, the fan 32 in the fan frame 31 is started to suck external air into the housing 1. Before the external air enters the housing 1, it enters the mounting cylinder through the air vent holes 431. Then, the air is filtered by the filter plate 42 in the mounting cylinder to prevent dust-laden air from being sucked in, which may cause the lens to be unable to be cleaned. The filtered air enters the air flow chamber 11 inside the housing 1 and is then discharged through the exhaust grooves 12. Since the exhaust grooves 12 are located at the lens of the infrared thermometer 2, the clean air can be smoothly blown onto the lens to remove the surface dust, avoiding the problem that after a brush and a cleaning cotton complete one cleaning, they will carry dust and are likely to bring the dust back to the surface of the lens of the infrared thermometer 2 during the second cleaning, and need to be replaced regularly. In addition, the servo motor drives the rotating seat 62 to rotate, thereby controlling the horizontal rotation of the two infrared thermometers 2, and starting the double-shaft motor 63 can drive the two infrared thermometers 2 to adjust the angle in the vertical direction.

[0041] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
