[0004] The above technical solution has a simple structure and strong practicality. Infrared spectroscopy is the ability of molecules to selectively absorb infrared rays of certain wavelengths, causing transitions in vibrational energy levels and rotational energy levels in molecules. Detecting the absorption of infrared rays can obtain the infrared absorption spectrum of the substance, and then determine the composition of the substance. However, if there is dust on the surface of the object to be detected, the dust may absorb or reflect part of the infrared rays, thereby interfering with the infrared spectrometer's detection of the surface of the object to be detected, which may cause changes in the spectrum graph. The above technical solution does not have a cleaning function, and in hot weather, the handle of the spectrometer may slip and become less comfortable due to sweating on the user's hands.

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1-Figure 6As shown, this embodiment provides a handheld infrared spectrometer, including a handheld handle 1 and a detection body 2, the handheld handle 1 is fixedly mounted on the bottom of the detection body 2, a display screen 3 is fixedly mounted on one end of the detection body 2, a translation drive component 4 is arranged on the top of the detection body 2, a detachable cleaning component 5 is fixedly connected to the translation drive component 4, and the detachable cleaning component 5 can be driven to move after the translation drive component 4 works, and a ventilation component 6 is installed on the handheld handle 1, and the ventilation component 6 can keep the handheld handle 1 ventilated.

[0025] The translation drive assembly 4 includes a rectangular cross plate 401 fixedly mounted on the top of the detection body 2, a mounting groove is provided on the top of the rectangular cross plate 401, a translation block 402 is slidably engaged in the mounting groove, a translation motor 403 is fixedly mounted on the outer wall of the rectangular cross plate 401, a translation screw 404 is fixedly mounted on the output shaft of the translation motor 403, a screw hole is provided on the translation block 402, one end of the translation screw 404 is passed through the screw hole, and the mounting groove on the top of the rectangular cross plate 401 can limit the translation block 402. At this time, the translation block 402 can only slide in the mounting groove but cannot rotate. Therefore, when the translation screw 404 rotates, it can drive the translation block 402 to move.

[0026] The detachable cleaning component 5 includes a cleaning motor 501 fixedly mounted on the top of the translation block 402, and a mounting block 502 with a connecting groove on the side is fixedly connected to the output shaft of the cleaning motor 501, and a disassembly block 503 is arranged in the connecting groove on the side of the mounting block 502, and fixed threaded holes are arranged on the disassembly block 503 and the mounting block 502, and a fixing screw 504 is passed through the fixing threaded hole, and a cleaning brush 505 is connected to the outer wall of the disassembly block 503. When the cleaning brush 505 needs to be replaced, the user can first unscrew the fixing screw 504, and then the user can take the disassembly block 503 out of the connecting groove on the side of the mounting block 502, and then the cleaning brush 505 can be removed, and then the user can replace the cleaning brush 505 with a new one.

[0027] The ventilation assembly 6 includes a ventilation plate 601, and fixed grooves are provided on both sides of the handheld handle 1. The ventilation plate 601 is fixed on the inner side wall of the fixed groove. An inner cavity is provided in the ventilation plate 601, and ventilation holes 602 are provided on the ventilation plate 601. The ventilation holes 602 are connected to the inner cavity. A mounting tube 603 is connected to the bottom of the handheld handle 1, and a blower fan 604 is fixedly connected to the inner side wall of the mounting tube 603.

After the blower fan 604 is working, external air can be introduced into the mounting tube 603 and the three-way pipe 605. Since the three-way pipe 605 is connected to the ventilation plate 601, the gas in the three-way pipe 605 can enter the inner cavity in the ventilation plate 601, and then the gas in the inner cavity can be discharged through the ventilation hole 602, so that the gas can be blown to the user's hand.

[0028] When the utility model is used, when testing the object to be tested, the user can first hold the hand-held handle 1, and then the user can use the original detection probe on the detection body 2 to detect the object to be tested, and the detection result can be displayed on the display screen 3. If there is dust on the surface of the object to be tested before the detection, the user can first make the translation motor 403 work and then drive the translation screw rod 404 to rotate. When the translation screw rod 404 rotates in place, it can drive the translation block 402 and the cleaning motor 501 to move, thereby driving the installation block 502, the disassembly block 503 and the cleaning brush 505 to move synchronously until the cleaning brush 505 moves to the detection body. After the side of the body 2 is turned on, it can be stopped, and then the user can make the cleaning motor 501 work to drive the mounting block 502 and the cleaning brush 505 to rotate. The user can clean the dust on the surface of the object to be detected through the rotating cleaning brush 505 to avoid affecting the detection result. In hot weather, the user can make the blower fan 604 work to introduce external air into the mounting tube 603, so that the air can enter the three-way pipe 605, and then the three-way pipe 605 can place the gas into the inner cavity of the ventilation plate 601, and finally the gas can be discharged through the ventilation hole 602, which reduces the possibility of slipping caused by sweating of the hands, and ventilation can also improve comfort.
