When cooperating with a dust particle counter, a floating bacteria sampler, and any other type of active gas sampling device, it can dynamically decompress the compressed gas to be measured into an approximately atmospheric pressure gas in real time and transport it to the backend sampling device.

[0003] The high-pressure diffusers in the prior art usually adopt a sealed chamber with a sufficiently large volume. When high-pressure gas enters the sealed chamber, the large-volume chamber causes the gas pressure to drop sharply to achieve high-pressure diffusion. However, the high-pressure diffuser using a large-volume sealed chamber for diffusion has a relatively large overall structure, and the manufacturing of the device relies on a large amount of raw materials, resulting in waste of resources. And usually, manual control is used to control the diffusion of the decompressed gas, and it is impossible to accurately provide the required gas volume when different detection devices are connected to the backend of the high-pressure diffuser. Summary of the Utility Model

Detailed implementation manner

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

It should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or several of such features. In the description of the present utility model, the meaning of "a plurality" and "several" is two or more, unless otherwise specifically defined.

[0023] Please refer to Figure 1 and Figure 2 simultaneously, and now the electronic high-pressure diffuser provided by the present utility model will be described. The electronic high-pressure diffuser includes a housing 10, a decompression component 20 and a controller. The housing 10 has an air inlet 11 and an air outlet 12. The air inlet 11 is used for introducing high-pressure gas; both ends of the decompression component 20 are communicated with the air inlet 11 and the air outlet 12 respectively. A solenoid valve 21 is provided on the decompression component 20. The solenoid valve 21 is used to control the gas flow rate of the air outlet 12; the controller is disposed on the housing 10 and is electrically connected to the solenoid valve 21 for controlling the opening degree of the solenoid valve 21.

[0024] It should be noted that high-pressure gas enters the decompression component 20 through the air inlet 11, and the solenoid valve 21 controls the gas flow rate discharged from the air outlet 12 to change the pressure of the discharged gas; the electronic high-pressure diffuser needs to be cleaned before use to create a relatively clean internal pipeline environment and avoid affecting the sampling results of the subsequent connected sampling equipment. By releasing high-pressure gas through the solenoid valve 21, the residual gas inside the housing 10 is discharged, so that only the high-pressure gas to be detected exists inside the housing 10, which is beneficial to improving the detection accuracy of the subsequent detection equipment; the solenoid valve 21 is a stop valve that automatically switches the switch 13 by electromagnetic force. It is a basic device for controlling the automation of objects and belongs to an actuator. It can be used to regulate the gas flow rate discharged from the solenoid valve 21; the opening degree of the solenoid valve 21 is the opening degree of the solenoid valve 21, which can affect the discharged gas flow rate through the opening degree. By controlling the opening degree of the solenoid valve 21 outside the housing 10 through the controller, the solenoid valve 21 can automatically decompress the high-pressure gas and improve the accuracy of the supplied gas.

[0025] The beneficial effects of the electronic high-pressure diffuser provided by the present utility model are as follows: Compared with the prior art, the present utility model uses the decompression component 20 to receive high-pressure gas, and the solenoid valve 21 controls the gas flow rate discharged from the air outlet 12. Compared with the method of increasing the volume of high-pressure gas through a large-volume sealed chamber to reduce the pressure of high-pressure gas, it can save the structural occupied space, reduce the amount of structural manufacturing raw materials, and save resources; when different detection equipment is connected after the high-pressure diffuser, the solenoid valve 21 controlled by the controller can accurately provide the required gas volume, which has higher accuracy compared with manual opening and closing control, and can be compatible with dust particle counters and floating bacteria samplers with different flow rates, and has stronger adaptability.

[0026] In a possible implementation manner, please refer to Figure 3 , the decompression component 20 includes an intake pipe 22, an outlet pipe 23 and a solenoid valve 21. The intake pipe 22 is communicated with the intake end of the solenoid valve 21; the outlet pipe 23 is communicated with the outlet end of the solenoid valve 21.

[0027] It should be noted that the decompression component 20 is a block with a certain structural strength, which can withstand the pressure of the high-pressure gas itself entering the decompression component 20 and avoid damage to the structure due to excessive gas pressure; the intake pipe 22 and the outlet pipe 23 are arranged inside the decompression component 20, and both the intake pipe 22 and the outlet pipe 23 are communicated with the solenoid valve 21, so that after the gas enters the intake pipe 22, the gas flow rate is controlled by the solenoid valve 21, and then discharged from the air outlet 12 through the outlet pipe 23. The outlet pipe 23 can supply the decompressed air flow to the subsequent detection equipment and improve the detection accuracy.

[0028] In a possible implementation manner, please refer to Figure 1, in a possible implementation, a detection component 30 is provided inside the housing 10. The detection component 30 is electrically connected to the controller. The detection component 30 is used to detect the gas pressure in the intake pipe 22 and feedback the pressure detection value to the controller.

[0029] It should be noted that the detection component 30 can detect whether there is high-pressure gas in the intake pipe 22. The high-pressure gas in the intake pipe 22 enters the detection component 30. The detection component 30 can detect the gas pressure in the intake pipe 22. By setting a normal pressure threshold for the detection component 30 and judging the gas pressure during real-time detection, it is possible to detect whether the pressure in the intake pipe 22 is normal or too high; judge the actual gas pressure in the intake pipe 22 to cooperate with the solenoid valve 21 to change the flow rate of the high-pressure gas discharged from the outlet pipe 23, so that the gas supply accuracy of the subsequent detection equipment becomes higher.

[0030] In a possible implementation, please refer to Figure 3 , the detection component 30 includes a detection pipe 31 and a barometric pressure sensor 32; one end of the detection pipe 31 is communicated with the intake pipe 22, and the other end is connected to the barometric pressure sensor 32.

[0031] It should be noted that the intake pipe 22 is provided with fastening screws and a sealing ring. The detection pipe 31 passes through the fastening screws and is communicated with the intake pipe 22, which can make the cooperation between the detection pipe 31 and the intake pipe 22 closer. The periphery of the connection between the detection pipe 31 and the intake pipe 22 is blocked by the fastening screws. When the intake pipe 22 is filled with high-pressure gas, the fastening screws can form a restraining effect on the detection pipe 31 to prevent the detection pipe 31 from detaching from the intake pipe 22 under the influence of internal high pressure; the sealing ring is sleeved on the connection between the detection pipe 31 and the fastening screws, which can enhance the connection airtightness between the detection pipe 31 and the intake pipe 22 and is beneficial to the detection accuracy of the high-pressure gas inside the intake pipe 22; the barometric pressure sensor 32 is an instrument for measuring the absolute pressure of the gas and can measure the actual gas pressure in the intake pipe 22.

[0032] In a possible implementation, please refer to Figure 4 , the housing 10 internally has a battery 40. The battery 40 is electrically connected to the controller.

[0033] It should be noted that the battery 40 provides electrical energy for the solenoid valve 21 and the detection component 30. The battery 40 is electrically connected to the solenoid valve 21 and the detection component 30 through the controller. The controller changes the air pressure state inside the decompression assembly 20 by controlling the solenoid valve 21 and the detection component 30; during the use of the electronic high-pressure diffuser, due to insufficient battery power or battery damage of the battery 40, the device may not be able to start. There is a battery cover on the back of the housing 10. When the electronic high-pressure diffuser cannot start, the housing 10 can be opened and a new battery 40 can be replaced to make the device work normally.

[0034] In a possible implementation, please refer to Figure 2 , on the outer surface of the housing 10, there is a switch 13 and an indicator light 14, and the switch 13 and the indicator light 14 are respectively electrically connected to the controller; wherein, the switch 13 is used to control the connection or disconnection between the battery 40 and the controller, and the indicator light 14 is used to display the working state of the decompression component 20 and the controller through the light.

[0035] It should be noted that the controller receives the signal from the switch 13 to connect or disconnect the battery 40 to achieve the switching operation of the electronic high-pressure diffuser; the light of the indicator light 14 can change, and the operator can identify the specific working state of each component inside the housing 10 by observing the indicator light 14, and adjust the device according to the real-time state displayed by the indicator light 14; the indicator light 14 is used to display the working state of the decompression component 20 and the controller. The decompression component 20 has multiple working states, and the controller can control the decompression component 20 to switch to the cleaning state. On the outer surface of the housing 10, there is also a cleaning button and a third lamp body. When the cleaning button is pressed, the third lamp body lights up. After the cleaning is completed, when the cleaning button is pressed again, the third lamp body goes out, and the decompression component 20 exits the cleaning state; the cleaning button can also switch the decompression component 20 to the decompression state. After the detection device completes the detection, the extraction of high-pressure gas is closed through the switch 13. When the cleaning button is pressed to make the third lamp body light up, at this time, the decompression component 20 enters the decompression state, and can release the residual gas in the pipeline. After the decompression is completed, when the cleaning button is pressed again, the third lamp body goes out, and the decompression component 20 exits the decompression state.

[0036] In a possible implementation, please refer to Figure 2 , the indicator light 14 includes a first lamp body 141 and a second lamp body 142. The first lamp body 141 is used to display the working state of the decompression component 20, and the second lamp body 142 is used to display the working state of the controller.

[0037] It should be noted that the first lamp body 141 is green when there is high-pressure gas in the decompression component 20 and the gas pressure is normal, turns red when the gas pressure in the decompression component 20 is too high, and goes out when there is no high-pressure gas in the decompression component 20; when the decompression component 20 is in the decompression state, the change of the first lamp body 141 is used to judge whether the residual gas in the decompression component 20 is completely released, and ensure that there is no residual gas in the decompression component 20 before exiting the decompression state, which is beneficial to maintaining a relatively clean gas pipeline environment; the electronic high-pressure diffuser is turned on and off through the switch 13. When the electronic high-pressure diffuser is in the on state and the internal power is greater than 50%, the second lamp body 142 is green; when the electronic high-pressure diffuser is in the on state and the internal power is between 20% and 50%, the second lamp body 142 is red; when the electronic high-pressure diffuser is in the on state and the internal power is less than 20%, the second lamp body 142 flashes red; when the electronic high-pressure diffuser is in the off state, the second lamp body 142 goes out.

[0038] In a possible implementation, please refer to Figure 4 , a charging interface 15 is provided on the housing 10, and the charging interface 15 is electrically connected to the controller.

[0039] It should be noted that the top of the housing 10 has a charging interface 15, which can charge the battery 40; a charging lamp is provided on the housing 10. By inserting an adapter into the charging interface 15 and charging the battery 40 through the controller, the real-time charging information of the battery 40 is displayed by the charging lamp; if the battery 40 cannot be charged or cannot be fully charged for a long time under normal circumstances of the adapter, the housing 10 needs to be opened and a new battery 40 needs to be replaced.

[0040] In a possible implementation, please refer to Figure 1 , a power interface 16 is provided at the top of the housing 10, and the power interface 16 is electrically connected to the battery 40.

[0041] It should be noted that the power interface 16 can connect to an external power supply and realize external power supply through electrical connection with the controller. When the battery 40 is short of power, there is no need to wait for the battery 40 to be charged, and fast power supply can be realized by connecting an external power supply to the power interface 16, which is beneficial to improving the working efficiency of the high-pressure diffuser.

[0042] In a possible implementation, please refer to Figure 2 , a connector 17 is provided on the air outlet 12, and the connector 17 is used to connect to the backend detection device.

[0043] It should be noted that the joint 17 has an internal thread and can be screwed and fitted with the air outlet 12. Before the electronic high-pressure diffuser is connected to the backend detection device, the joint 17 is first installed on the air outlet 12, and the air outlet 12 is in close contact with the joint 17 to prevent the decompressed gas from leaking. The models of the joint 17 can be Ф6, Ф8, Ф10.8, Ф14, Ф16, Ф20, which can adapt to connecting pipes of different diameters, can change the flow rate of the air flow, so as to meet the actual gas consumption requirements of different detection devices, and has stronger adaptability.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
