Description

Technical Field

[0001] The utility model belongs to the field of mass spectrometers, and particularly relates to a pipeline component suitable for a mass spectrometer and a mass spectrometer. Background Art

[0002] A mass spectrometer is an analytical instrument that uses the mass-to-charge ratio after ionization of molecules or atoms to determine the composition and structure of a sample. Its working principle is based on the principle that charged particles can be deflected in an electromagnetic field. It separates and detects the atoms, molecules or molecular fragments of a substance according to their mass differences, thereby realizing the analysis of the composition of the substance. With the rapid development of the domestic electrical industry, mass spectrometers have been widely used in lithium battery leakage detection scenarios. For example: Application No. 202311816948.X, named, Electrolyte Leakage Detection Method and Device, discloses the use of a mass spectrometer to detect the leakage of lithium batteries.

[0003] To accurately detect the sample being measured, a mass spectrometer is typically equipped with a pipeline. This pipeline allows the sample (a gas) to flow. However, in existing technologies, after the sample passes through the pipeline, some sample often remains inside. Consequently, when the mass spectrometer is used again to detect the object, this residual sample will undoubtedly lead to errors in the test results, ultimately reducing detection accuracy. Utility Model Content

[0004] The utility model provides a pipeline component suitable for a mass spectrometer, which aims to solve the problem of reduced detection accuracy caused by residual samples.

[0005] In order to achieve the above object, the utility model provides a pipeline assembly suitable for a mass spectrometer, comprising

[0006] A connecting pipe and a sample pipe, wherein the connecting pipe is in communication with the sample pipe, and the sample pipe is used for the flow of the sample to be tested;

[0007] a pump body, the pump body being mounted on the connecting pipe, and the connecting pipe being in communication with the pump body;

[0008] a first valve, which is provided in the connecting pipe and installed at the outlet end of the pump body, and can open or close the connecting pipe;

[0009] A clean air providing device includes an air storage bag and / or an air purifier, the air storage bag and the air purifier are connected to the pump body, and the pump body is used to inject clean air into the sample pipe to clean the sample pipe.

[0010] In this solution, clean air is injected into the sample pipe through the pump body. After the clean air is injected into the sample pipe, the clean air takes away the residual sample to be tested inside the sample pipe, thereby solving the problem that the residual sample to be tested affects subsequent testing and solves the problem that the residual sample to be tested causes a decrease in detection accuracy.

[0011] Preferably, to enable inflation into the air bag, the air bag is detachably connected to the pump inlet via a removable structure. This embodiment provides a detachable connection between the air bag and the pump inlet. When the air bag is separated from the pump, clean air can be introduced into the air bag. When the air bag is connected to the pump, the pump can then pump the clean air out of the air bag.

[0012] In order to inflate the air bag, the air bag of this solution is provided with an inflation port. This solution inflates the air bag through the inflation port.

[0013] To ensure the airbag remains sealed during inflation, the airbag system preferably includes a second valve installed in the connecting pipe at the outlet of the airbag. This valve closes the connecting pipe, sealing the airbag. Once the airbag is sealed, clean gas is injected into the airbag, preventing leakage.

[0014] Preferably, in order to avoid negative pressure inside the air storage bag, the air storage bag of this solution is a rubber elastic air bag. The rubber elastic air bag stores clean gas inside. When the clean gas is pumped out by the pump body, the air storage bag can be deformed accordingly, thereby solving the problem of negative pressure inside the air storage bag.

[0015] Preferably, in order to prevent impurities from adhering to the interior of the pump body, the air purifier is installed at the inlet end of the pump body. In this solution, when the air purifier is installed at the inlet end of the pump body, the air purifier purifies the gas before the air enters the pump body, thereby avoiding the problem of impurities adhering to the pump body.

[0016] Preferably, in order to determine the vacuum degree of the sample pipe, the present solution further includes a vacuum gauge, which is installed in the sample pipe and is used to detect the internal air pressure of the sample pipe.

[0017] Preferably, the device further comprises a control module, wherein the control module is connected to the pump body and the first valve signal.

[0018] The second aspect of the present invention discloses a mass spectrometer, comprising the above-mentioned pipeline assembly. By applying the above-mentioned pipeline assembly to the mass spectrometer, the pipeline assembly can solve the problem that the mass spectrometer is affected by residual measured samples.

[0019] The beneficial effect of the present utility model is that in this solution, clean air is injected into the sample pipe through the pump body. After the clean air is injected into the sample pipe, the clean air takes away the residual sample to be tested inside the sample pipe, thereby solving the problem that the residual sample to be tested affects subsequent testing and solves the problem that the residual sample to be tested causes a decrease in detection accuracy.

DETAILED DESCRIPTION

[0026] To make the objectives, technical solutions, and advantages of the embodiments more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, identical numbers in different drawings represent identical or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0027] It should be noted that all actions of obtaining signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0028] In this disclosure, unless otherwise specified, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" are used in this disclosure to distinguish one element from another and do not convey order or importance.

[0029] Example 1

[0030] Basically as attached Figure 1 As shown, a pipeline assembly suitable for a mass spectrometer includes a connecting pipeline, a sample pipeline, a pump body, a first valve, a second valve, a vacuum gauge, a clean air providing device and a control module.

[0031] like Figure 1 As shown, the connecting pipe and sample pipe in the disclosed embodiment are arranged in a T-shape. Both the connecting pipe and the sample pipe are metal pipes, preferably stainless steel. The sample pipe is used to pass the sample to be tested, allowing the sample to enter the mass spectrometer. The connecting pipe is used to install the pump body, the first valve, the second valve, and the clean air supply device, and the connecting pipe and the sample pipe are in a connected state.

[0032] like Figure 1 As shown, the pump body in the embodiment of the present disclosure is installed on the connecting pipe, and the outlet of the pump body is connected to the sample pipe. When the pump body is working, clean air is injected from the connecting pipe into the interior of the sample pipe. The first valve is also installed on the connecting pipe, and is installed in the direction of the outlet end of the pump body. The first valve is preferably an electric valve, and the first valve is used to close or open the connecting pipe. When the first valve is installed in the direction of the outlet end of the pump body, when the first valve closes the connecting pipe, the sample to be tested inside the sample pipe will not enter the pump body, thereby preventing the sample to be tested from remaining inside the pump body.

[0033] The clean air supply device in the disclosed embodiment includes an air storage bag connected to the inlet of a pump body. The air storage bag is preferably a rubber bag and can store clean air. When the air storage bag is filled with clean air, the air storage bag is in an expanded state; when the clean air in the processing bag is withdrawn, the air storage bag contracts.

[0034] It should be noted that, in order to inflate the air storage bag, an inflation port can be provided on the air storage bag in the disclosed embodiment. A nozzle can be installed at the port to allow clean air to be introduced into the air storage bag. Alternatively, the outlet of the air storage bag can be detachably connected to a connecting pipe via a flange. Once the air storage bag is removed, clean air can be refilled.

[0035] A second valve, also an electric valve, is located at the pump inlet. This valve can seal the connecting pipe. Installed at the outlet of the air reservoir, the second valve seals the connecting pipe, completely sealing the air reservoir.

[0036] like Figure 2 and Figure 3As shown, in order to detect the contraction state of the air bag, the user is reminded to inflate the air bag in time. In the embodiment of the present disclosure, a detection module is also configured on the air bag. The detection module includes a first detection block and a second detection block. The first detection block and the second detection block are metal blocks, specifically copper blocks. The top and the bottom of the air bag are respectively provided with a first mounting plate and a second mounting plate, and the first detection block and the second detection block are respectively installed on the inner side of the first mounting plate and the second mounting plate. The first detection block and the second detection block are respectively connected to the two ends of the detection circuit. At the same time, an alarm is also configured in the detection circuit. The alarm can be a speaker or a warning light.

[0037] Take an application scenario as an example: when the airbag shrinks, the top and bottom of the airbag approach each other. When the top and bottom of the airbag approach each other, the first detection block and the second detection block can come into contact. Since the first detection block and the second detection block are respectively connected to the two ends of the detection circuit, when the first detection block and the second detection block come into contact with each other, the detection circuit is connected. When the detection circuit is connected, the alarm in the detection circuit works, thereby reminding the user to replenish air in time. Of course, a signal transmitter can also be configured in the detection circuit, and the signal transmitter can be a laser transmitter. The signal transmitter is electrically connected to the control module. When the detection circuit is turned on, the signal transmitter sends a signal to the control module.

[0038] It is understandable that when the control module receives the signal sent by the signal transmitter, the control module can control the pump body to stop working. The first valve and the second valve close the connecting pipe to prevent clean air from entering the sample pipe.

[0039] like Figure 1 As shown, the clean air providing device in the embodiment of the present disclosure further includes an air purifier, which is installed between the pump body and the air storage bag, and is located at the inlet end of the air storage bag. The air purifier purifies the air output from the air storage bag, thereby further reducing impurities in the gas.

[0040] It should be noted that: the embodiment of the present disclosure is equipped with both an air storage bag and an air purifier. The air storage bag stores clean air, and the air purifier then purifies the air again. The air storage bag and the air purifier work together to ensure that the gas entering the sample channel is cleaner. However, in some other embodiments, only one of the air storage bag and the air purifier can be configured, such as Figure 4 and Figure 5 As shown, the air purifier purifies the air mixed with impurities into clean air by storing clean air in an air storage bag.

[0041] like Figure 1As shown, the vacuum gauge in the disclosed embodiment is installed on the sample pipe and is used to measure the vacuum level in the sample pipe. When the vacuum gauge detects a high vacuum level inside the sample pipe, it indicates that the sample pipe is in an operating state. At this time, the control module will not control the first valve to open, and air will enter the sample pipe, causing the vacuum level to drop.

[0042] In the embodiment of the present disclosure, the pump body, the first valve, the second valve, the vacuum gauge and the air purifier are all communicatively connected to a control module. The control module may be a PLC control module, a single chip microcomputer control module or an industrial computer control module.

[0043] The following describes a specific embodiment in further detail: When the sample line needs to be cleaned, the controller opens both the first and second valves, and the pump injects clean air into the sample line. Once the clean air enters the sample line, it flushes any remaining sample out of the sample line outlet, preventing it from affecting test accuracy.

[0044] Example 2

[0045] The present disclosure discloses a mass spectrometer, which utilizes the pipeline assembly in Example 1. Specifically, the sample pipeline in Example 1 is used as a pipeline in the mass spectrometer for passing the sample to be measured.

[0046] When the pipeline assembly in Example 1 is applied to a mass spectrometer, the pipeline assembly can clean the pipeline and prevent the mass spectrometer from being affected by residual measured samples.

[0047] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
