[0043] See also Figure 1 , Figure 1 The gas source device 1 provided in the embodiment of the present application is used to provide pressure for a sample analyzer, and includes a frame 10, an air pump 11, an air storage tank 12, a first heat dissipation component 131 and a controller (not shown).

[0044] The frame 10 has a first accommodation space and a second accommodation space; the air pump 11 is located in the first accommodation space for generating pressure; the air tank 12 is located in the second accommodation space, and the air tank 12 is connected to the air outlet of the air pump 11; the first heat dissipation component 131 is located in the second accommodation space and is spaced apart from the air tank 12. In one embodiment, the first heat dissipation component 131 may be a heat dissipation fan.

[0045] The controller is connected to the air pump 11 and the first heat dissipation component 131 respectively, and is used to control the air pump 11 to generate gas and store the gas in the gas storage tank 12. The air pump 11 provides pressure to the sample analyzer through the gas storage tank 12. The controller is also used to control the first heat dissipation component 131 to open, and the first heat dissipation component 131 is used to dissipate heat from the gas storage tank 12.

[0046] Specifically, when the air pump 11 is working and generating gas, heat will be generated at the same time, and the gas will carry heat. In this application, the gas with heat is first stored in the gas storage tank 12, and the first heat dissipation component 131 is spaced apart from the gas storage tank 12 to dissipate heat in the space around the gas storage tank 12, and then dissipate heat in the gas stored in the gas storage tank 12. When the sample analyzer needs to provide pressure, the air pump 11 provides the heat-dissipated gas to the sample analyzer through the gas storage tank 12 to provide pressure to the sample analyzer, thereby avoiding the heat generated by the air pump 11 from being transferred to the inside of the gas source device 1 and affecting the working performance of the air pump 11, thereby improving the safety and practicality of the gas source device 1. At the same time, it can avoid providing the sample analyzer with hot gas and affecting the internal devices of the sample analyzer, resulting in changes in the performance of the sample analyzer, thereby improving the reliability of the gas source device 1.

[0047] In one embodiment, the gas tank 12 can be made of a material with good heat dissipation performance such as metal, and then when the first heat dissipation component 131 dissipates heat from the gas tank 12, the gas with heat stored inside the gas tank 12 will transfer the heat to the surface of the gas tank 12, and the first heat dissipation component 131 forms an airflow to take away the heat from the surface of the gas tank 12, and then the first heat dissipation component 131 realizes heat dissipation of the second accommodating space (the surface of the gas tank 12) and the gas inside the gas tank 12.

[0048] In summary, the air pump 11 stores the generated gas in the gas tank 12, and provides pressure to the sample analyzer through the gas tank 12. The first heat dissipation component 131 is spaced apart from the gas tank 12 to dissipate heat from the gas tank 12, and then dissipate heat from the second accommodation space, and even the first accommodation space, to provide a good working environment for the components inside the gas source device 1, such as the air pump 11, to improve the working performance of the air pump 11, and to improve the practicality of the gas source device 1. The first heat dissipation component 131 dissipates heat from the gas inside the gas tank 12 to prevent the air pump 11 from providing the sample analyzer with gas carrying heat, causing the outlet temperature of the gas source device 1 to be too high, the air flow near the outlet to be turbulent, or the components inside the sample analyzer to be damaged by the gas carrying heat, causing the risk of performance changes in the sample analyzer, thereby improving the reliability of the gas source device 1.

[0049] Optional, see Figure 2 , Figure 2 The air source device 1 further comprises a first support plate 141 and a second support plate 142 .

[0050] The first support plate 141 and the second support plate 142 are disposed on the frame body 10 at intervals, and the first support plate 141, the second support plate 142 and the frame body 10 form a first accommodation space, and the first support plate 141 and the frame body 10 form a second accommodation space.

[0051] Specifically, the air pump 11 is disposed on the second support plate 142, and the air tank 12 and the first heat dissipation assembly 131 are disposed on the first support plate 141. The air pump 11 is separated from the air tank 12 and the first heat dissipation assembly 131, so that the heat or vibration generated when the air pump 11 is working can be prevented from affecting the air tank 12 and the first heat dissipation assembly 131, and the airflow range generated by the first heat dissipation assembly 131 is expanded, thereby improving the heat dissipation efficiency of the first heat dissipation assembly 131 to the first accommodation space and the second accommodation space.

[0052] Optional, please continue to Figure 1 The air source device 1 further includes an air intake assembly 15, which is disposed on the first support plate 141 and connected to the air inlet of the air pump 11. The controller is used to control the air pump 11 and the air intake assembly 15 to start. The air intake assembly 15 absorbs gas from the environment to provide gas for the air pump 11. The air pump 11 compresses the gas and stores the compressed gas in the gas storage tank 12.

[0053] In one embodiment, the air intake component 15 can be an air intake filter. When the air intake component 15 absorbs gas from the environment to pass the gas through the air pump 11, the air intake component 15 first filters out other impurities in the environment, such as dust, to prevent other impurities from entering the air pump 11 through the air intake component 15 and blocking the connection pipe between the air intake component 15 and the air pump 11 or damaging the interior of the air pump 11, thereby improving the safety of the air source device 1.

[0054] Furthermore, the controller is connected to the gas storage tank 12. When the air pump 11 provides pressure to the sample analyzer, the controller is also used to control the gas storage tank 12 to provide compressed gas to the sample analyzer.

[0055] Specifically, the air pump 11 stores the compressed gas in the gas tank 12, and the first heat dissipation component 131 dissipates the heat of the gas in the gas tank 12. Then, when the air pump 11 provides pressure for the sample analyzer, the controller controls the gas tank 12 to provide the sample analyzer with the dissipated gas, so as to avoid the gas temperature being too high, causing the temperature of the gas outlet connected to the gas source device 1 and the sample analyzer to be too high, affecting the gas flow near the gas source device 1, or causing damage to the internal components of the sample analyzer, causing the risk of performance changes of the sample analyzer, thereby improving the reliability of the gas source device 1.

[0056] In addition, the air pump 11 stores the compressed gas in the gas tank 12. When the controller responds to the sudden increase in pressure required by the sample analyzer, the controller can directly control the gas tank 12 to provide the required gas to the sample analyzer without waiting for the air pump 11 to operate, thereby improving the response speed of the gas source device 1.

[0057] Optionally, see Figure 1 , Figure 2 and Figure 3 , Figure 3 1 is a schematic structural diagram of the third embodiment of the air source device of the present application. One side of the frame 10 includes an air inlet 101, and the air inlet 101 is connected to the second accommodation space.

[0058] The air source device 1 further includes an ash blocking member 16, which is disposed on the first support plate 141 and is located between the air inlet 101 and the first heat dissipation assembly 131. When the controller controls the first heat dissipation assembly 131 to be turned on, the first heat dissipation assembly 131 drives the gas in the environment to enter the second accommodation space from the air inlet 101 to form a gas flow, and dissipate heat from the gas storage tank 12.

[0059] In one embodiment, the dust blocking member 16 may be dust blocking cotton. When the gas enters the second accommodation space from the air inlet 101, the dust blocking member 16 filters the gas entering from the air inlet 101 to prevent other impurities in the environment from entering the second accommodation space, covering the first heat dissipation component 131 to affect the operation of the first heat dissipation component 131, or covering the surface of the gas storage tank 12 to affect the heat dissipation of the gas storage tank 12. In this embodiment, the dust blocking member 16 is arranged at the air inlet 101 to filter the gas entering the second accommodation space, thereby improving the working performance of the first heat dissipation component 131.

[0060] Optionally, the first support plate 141 includes a first exhaust hole, and the first heat dissipation component 131 is disposed in the first exhaust hole, so that the first heat dissipation component 131 can form an airflow from the second accommodating space to the first accommodating space to dissipate heat in the second accommodating space and the first accommodating space.

[0061] The air source device 1 further includes a second heat dissipation component 132, which can be a heat dissipation fan. The second support plate 142 includes a second exhaust hole, and the second heat dissipation component 132 is disposed in the second exhaust hole. The second support plate 142 and the frame 10 form a third accommodation space, and the second heat dissipation component 132 can form an airflow from the second accommodation space to the third accommodation space to dissipate heat in the second accommodation space.

[0062] One side of the frame 10 also includes an air outlet 102, which is connected to the third accommodation space. The controller is connected to the second heat dissipation component 132, and is used to control the first heat dissipation component 131 and the second heat dissipation component 132 to be turned on. The first heat dissipation component 131 drives the gas to enter the second accommodation space from the air inlet 101, and enter the first accommodation space through the first exhaust hole; the second heat dissipation component 132 drives the gas in the first accommodation space to enter the third accommodation space through the second exhaust hole, and is discharged through the air outlet 102 to dissipate heat in the first accommodation space.

[0063] In one embodiment, the air inlet 101 and the air outlet 102 may both be composed of a plurality of strip-shaped holes to improve the aesthetics of the frame 10 .

[0064] Specifically, the first heat dissipation component 131 is turned on, and the gas enters the second storage space from the air inlet 101, and an airflow is formed in the second storage space to dissipate the heat of the gas tank 12. At the same time, the gas carrying the heat of the gas tank 12 enters the first storage space through the first exhaust hole. In the process of the first heat dissipation component 131 sending the gas from the second storage space into the first storage space, an airflow from the second storage space to the first storage space will be formed to dissipate the heat of the air pump 11. Further, the second heat dissipation component 132 forms an airflow from the first storage space to the third storage space, and transports the gas carrying the heat of the gas tank 12 and the heat of the air pump 11 to the third storage space, and discharges the gas carrying the heat through the air outlet 102. The airflow that circulates inside the air source device 1 is formed by the first heat dissipation component 131 and the second heat dissipation component 132, and the air source device 1 is dissipated, so that the internal components of the air source device 1 operate in a suitable environment, thereby improving the operating efficiency of the air source device 1.

[0065] Among them, the first heat dissipation component 131 and the air intake component 15 are both arranged in the second accommodating space. When the first heat dissipation component 131 and the air intake component 15 are turned on at the same time, the wind pressure formed by the air intake component 15 will be greater than the wind pressure formed by the first heat dissipation component 131, and then the gas will preferentially enter the air pump 11 through the air intake component 15, so that the air pump 11 compresses the gas.

[0066] Optional, please continue to Figure 1 The air source device 1 also includes at least one elastic member 17 .

[0067] Among them, the elastic member 17 is arranged between the air pump 11 and the second support plate 142. In one embodiment, the elastic member 17 can be a spring member, which is arranged at the four corners of the air pump 11. During the operation of the air pump 11, the vibration generated by the operation of the air pump 11 is reduced to improve the stability of the air source device 1.

[0068] Among them, the air source device 1 can also include a fixing part, which is arranged corresponding to the elastic part 17. Then, during the transportation of the air source device 1, the fixing part is sleeved on the outside of the elastic part 17 to fix the elastic part 17, and replace the elastic part 17 to support the air pump 11, so as to avoid the elastic part 17 and the air pump 11 shaking during transportation, causing damage to the elastic part 17, or the air pump 11 colliding inside the air source device 1, thereby improving the safety of the air source device 1 during transportation.

[0069] Optional, see Figure 2 The gas source device 1 also includes a relay 18 and a temperature sensor 19 .

[0070] Among them, the relay 18 is arranged on the second support plate 142, and is spaced from the air pump 11, and the relay 18 is connected to the air pump 11, and the controller is connected to the relay 18, and the opening of the air pump 11 is controlled by the relay 18. Among them, the relay 18 is an ideal element for weak current to control strong current, and its input control voltage is low, and the input control voltage is compatible with levels such as TTL (Transistor-Transistor-Logic, transistor-transistor logic level), VMOS (Vgroove metal oxide semiconductor, power field effect tube). And the relay 18 has input and output isolation insulation, safe and reliable, and has the advantages of no contact, no noise, no sparks, etc. When the input end receives the signal sent by the controller, the switch is closed, and the circuit at the output end starts to work. The weak current control of the strong current of the relay 18 can well play to its strengths and avoid its weaknesses, making the use of electricity by the gas source device 1 safer.

[0071] The temperature sensor 19 is disposed on the second support plate 142 and is located between the relay 18 and the air pump 11. The controller is connected to the temperature sensor 19, and the temperature sensor 19 is used to obtain the temperature in the first accommodating space. The controller is used to control the air pump 11 to shut down through the relay 18 when the temperature is higher than the preset temperature.

[0072] Specifically, the temperature sensor 19 monitors the temperature around the air pump 11 and the relay 18 in the first accommodation space, and the controller receives the temperature obtained by the temperature sensor 19. At the same time, a preset temperature is stored in the controller, wherein the preset temperature may be a temperature exceeding the normal operation temperature of the air pump 11, and when the temperature monitored by the temperature sensor 19 is higher than the preset temperature, the temperature in the first accommodation space is too high and is not suitable for the operation of the air pump 11, the controller controls the relay 18 to turn off, and the relay 18 stops supplying power to the air pump 11 to turn off the air pump 11, so as to prevent the air pump 11 from operating in an environment with too high a temperature, thereby damaging the working performance of the air pump 11 and improving the safety of the air source device 1.

[0073] Furthermore, in the above case, if the controller receives a request from the sample analyzer to provide pressure, the controller can directly control the gas storage tank 12 to provide gas to the sample analyzer without waiting for the air pump 11 to restart, thereby improving the stability of the pressure provided by the gas source device 1 to the sample analyzer.

[0074] It can be understood that, in the case where the gas source device 1 provided in this embodiment does not need to provide pressure to the sample analyzer at the moment, the controller can still control the air pump 11 and the air intake assembly 15 to start, and the gas generated by the air pump 11 is stored in the gas storage tank 12. When the sample analyzer requires pressure, the controller directly controls the gas storage tank 12 to provide gas to the sample analyzer. That is, due to the existence of the gas storage tank 12, the start-up time period of the air pump 11 is not limited to the time period for providing pressure to the sample analyzer, thereby achieving the response rate and stability of the gas source device 1 in providing pressure to the sample analyzer.

[0075] In one embodiment, the temperature sensor 19 can monitor the temperature in the first accommodating space in real time, and when the temperature monitored by the temperature sensor 19 is lower than a preset temperature, the controller controls the air pump 11 to restart.

[0076] Optionally, a pressure regulating valve 103 is further provided on one side of the frame 10 , and the pressure regulating valve is connected to the gas storage tank 12 to adjust the pressure provided by the gas storage tank 12 to the sample analyzer.

[0077] Specifically, the user can adjust the air pressure regulating valve 103 on one side of the frame 10 to control the parameters of the gas tank 12, such as the size of the gas outlet of the gas tank 12, the pressure inside the gas tank 12 that pushes the gas output, etc., to adjust the gas flow provided by the gas tank 12 to the sample analyzer, and then adjust the pressure provided by the gas tank 12 to the sample analyzer, and adjust the pressure entering the sample analyzer to a reasonable value, so as to avoid a large impact of the pressure on the devices in the sample analyzer causing the performance of the sample analyzer to change, thereby improving the reliability of the gas source device 1.

[0078] Optionally, see Figure 4 , Figure 4 The air source device 1 further comprises a housing 20 and a muffler 21 .

[0079] The housing 20 is disposed correspondingly to the frame 10. Figure 4 As shown, the housing 20 can be covered on the frame 10 to isolate the internal components of the air source device 1, such as the air pump 11, the air storage tank 12, the first heat dissipation component 131, etc. from the external environment, thereby improving the aesthetics of the air source device 1.

[0080] The silencer 21 may be a silencer cotton, which is arranged on the side walls of the shell 20 and the frame 10 to absorb the noise generated by the operation of the air pump 11, the first heat dissipation component 131 and the second heat dissipation component 132, to avoid excessive noise during the operation of the air source device 1, and to improve the user's experience of using the air source device 1.

[0081] In summary, the gas source device 1 provided in the embodiment of the present application includes an air pump 11, an air storage tank 12, a first heat dissipation component 131, a controller, a second heat dissipation component 132, a relay 18, a temperature sensor 19, etc. The frame 10 is divided into a first accommodation space, a second accommodation space, and a third accommodation space by a first support plate 141 and a second support plate 142. The air pump 11, the relay 18, and the temperature sensor 19 are arranged in the first accommodation space, and the air storage tank 12 is arranged in the second accommodation space to prevent the air storage tank 12 from being affected by the heat generated by the operation of the air pump 11. The gas generated by the air pump 11 is stored in the air storage tank 12, and the first heat dissipation component 131 is used to dissipate the gas in the air storage tank 12, thereby reducing the temperature of the gas provided by the air pump 11 to the sample analyzer, avoiding the risk of performance changes of the sample analyzer caused by excessive temperature, and improving the reliability of the gas source device 1.

[0082] At the same time, the first heat dissipation component 131 and the second heat dissipation component 132 form a stable airflow in the second accommodating space, the first accommodating space and the third accommodating space to carry away the heat of the gas storage tank 12 and the air pump 11, avoid the internal temperature of the gas source device 1 from being too high, and improve the safety of the gas source device 1.

[0083] The relay 18 is used to control the strong current through the weak current, thereby improving the circuit safety inside the gas source device 1. The temperature sensor 19 monitors the temperature inside the first accommodation space, so that the controller can timely control the operation of the air pump 11 through the temperature monitored by the temperature sensor 19, further improving the safety of the gas source device 1.

[0084] The present application also provides a sample analyzer system, including a sample analyzer and an air source device 1, wherein the air source device 1 is connected to the sample analyzer and is used to provide pressure to the sample analyzer so that the sample analyzer performs a sample detection operation.
