Technical Field

[0001] The utility model belongs to the technical field of gas analysis, and in particular relates to an inert gas analyzer. Background Art

[0002] The inert gas analyzer is a practical device that can quickly detect the inert gas content in the insulating glass spacer layer. It can be widely used in various scenarios such as insulating glass deep processing enterprises, door and window manufacturers and laboratories.

[0003] At present, most inert gas analyzers detect the inert gas content through destructive methods. This method is usually reasonably priced and has good accuracy, but it requires destroying the insulating glass spacer structure. In practice, this detection method means that the insulating glass cannot be delivered to customers after detection, and it cannot ensure that the insulating glass products delivered to customers have accurate inert gas concentrations.

[0004] Therefore, how to provide an effective solution to ensure that the insulating glass products delivered to customers have an accurate inert gas concentration has become a difficult problem to be solved in the prior art. Utility Model Content

[0034] The coding control module is used to generate a trigger signal in response to a user's trigger operation and convert the trigger signal into a digital voltage signal. The specific coding control module includes a key circuit and an encoder, the key circuit is electrically connected to the encoder, wherein the key circuit is used to generate a trigger signal in response to a user's trigger operation (such as a key operation), and the encoder is used to convert the generated trigger signal into a digital voltage signal.

[0035] The voltage processing module is used to convert the digital voltage signal into a DC voltage signal of a first preset voltage value, and to convert the DC voltage signal of the first preset voltage value into an AC voltage signal of the first preset voltage value. Specifically, the voltage processing module includes a transformer and an inverter electrically connected to the transformer, the transformer is used to convert the digital voltage signal into a DC voltage signal of a first preset voltage value, and the inverter is used to convert the DC voltage signal of the first preset voltage value into an AC voltage signal of the first preset voltage value. The first preset voltage value can be set according to actual conditions, for example, it can be 500V, 1000V or 1500V, etc. In the embodiment of the present application, the first preset voltage value is 1000V. Figure 2(a) , 2(b) 2(c) is a circuit diagram of a voltage processing module provided in an embodiment of the present application.

[0036] The spark discharge module is electrically connected to the voltage processing module, and is used to boost the AC voltage signal of the first preset voltage value to an AC voltage signal of the second preset voltage value in order to generate an arc. Specifically, the spark discharge module includes a spark discharge circuit and a driving circuit of the spark discharge circuit. The driving circuit is used to drive the spark discharge circuit. The spark discharge circuit is provided with a transformer, which is used to boost the AC voltage signal of the first preset voltage value to a second preset voltage value. The second preset voltage value can be set according to the actual equipment, as long as it is ensured that the spark discharge circuit can generate an arc at the second preset voltage value. For example, the second preset voltage value can be 50000V, 55000V or 60000V, etc. In the embodiment of the present application, the second preset voltage value is 50000V. Figure 3 As shown in FIG. 1 , it is a circuit diagram of a spark discharge circuit provided in an embodiment of the present application, such as Figure 4 , which is a circuit diagram of a driving circuit of a spark discharge circuit provided in an embodiment of the present application.

[0037] The optical fiber circuit module is used to collect the intensity of at least one light in the electric arc. Specifically, the optical fiber circuit module includes a CCD (Charge-Coupled Device) receiver and an amplifier electrically connected to the CCD receiver, wherein the CCD receiver is used to collect the intensity of at least one light in the electric arc, and the amplifier is used to amplify the intensity of at least one light.

[0038] In an embodiment of the present application, at least one light ray can be determined according to the inert gas to be tested.

The intensity of various lights in the arc generated by the spark discharge module in the insulating glass product will have certain differences. After the optical fiber circuit module collects the intensity of at least one light, the intensity of the at least one light can be sent to the control module. The control module determines the content of the inert gas to be tested according to the intensity of the at least one light. In the embodiment of the present application, the control module adopts the ATmega128A-AUR chip and its peripheral circuits. It can be understood that the control module can also adopt other chips.

The display screen may be used to display the detected content of the inert gas to be tested. The display screen may also be used to display other information, such as the current time and date, and the current time and date and other information may be modified and set.

[0041] When the concentration of the inert gas in the insulating glass product is detected by the inert gas analyzer, the spark discharge module can be placed in the spacer layer of the insulating glass product first, and the key circuit can be manually triggered at this time. The key circuit generates a trigger signal in response to the user's trigger operation, and converts the trigger signal into a digital voltage signal through an encoder. The voltage processing module converts the digital voltage signal into a DC voltage signal of a first preset voltage value through a transformer, and then converts the DC voltage signal of the first preset voltage value into an AC voltage signal of a first preset voltage value through an inverter. The spark discharge module boosts the AC voltage signal of the first preset voltage value to an AC voltage signal of a second preset voltage value and generates an arc, and then the intensity of at least one light in the arc is collected through the CCD receiver of the optical fiber circuit module, and the intensity of at least one light is amplified by an amplifier. Finally, the control module determines the content of the inert gas to be measured according to the intensity of the amplified at least one light, and displays it on the display screen. During this process, it is only necessary to place the spark discharge module in the insulating glass spacer layer, which will not damage the structure of the insulating glass product, ensuring that the insulating glass products delivered to customers have accurate inert gas concentration, and can be used as evidence for evaluating the quality of insulating glass products, facilitating practical application and promotion.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
