The proportioning device can accurately complete the proportion between the gases. Finally, the filling can be conveniently completed through the compressor and the filling pipe. The operation is convenient, and the protection component can play a good protective effect on the gas cylinder.

[0004] In the above patent, a buffer elastic member is provided in the protection component to reduce the impact caused by accidents to the gas storage cylinder. However, the protection component can only impose certain restrictions on the left and right shaking of the bottle body. When the impact is large and causes the bottle body to move up and down in the device, the air intake pipe may be shaken together, thereby increasing the risk of accidents in the air intake pipe, such as gas leakage. Therefore, it is necessary to provide a multi-gas medium proportioning device with a reinforcement device to solve the above problems.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a multi-gas medium proportioning device to achieve the effect of stably connecting the gas tank and the connecting pipe when subjected to impact or collision.

[0008] Furthermore, at least two groups of guide rods are arranged on the top of the pressing plate, and one end of the guide rod away from the pressing plate passes through the fixed plate.

[0009] Furthermore, a bolt is provided at one end of the guide rod away from the pressure plate.

[0010] Furthermore, an electric pressure regulating valve and a high-frequency solenoid valve are arranged on the branch pipe.

[0011] Furthermore, a pressure sensor is provided on the premixing tank.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0025] like Figure 1 As shown, the present application provides a multi-element gas medium proportioning device, including a box body 1, wherein a mixing mechanism 2 is arranged inside the box body 1, and the mixing mechanism 2 is used to proportion the multi-element gas medium. At the same time, a wheel group is arranged at the bottom of the box body 1, so that the box body 1 can be quickly moved between multiple groups of laboratories or workstations, thereby improving work efficiency and convenience, saving time and labor costs.

[0026] like Figure 2-Figure 5As shown, the mixing mechanism 2 includes a box body 1 with multiple layers of accommodating chambers 11 arranged from top to bottom, wherein the accommodating chamber 11 at the bottom is provided with a gas storage mechanism 3, and the gas storage mechanism 3 includes multiple groups of gas cylinders 31, and multiple gas sources are stored in the gas cylinders 31, and the gas sources can be replaced at will according to the use needs. At the same time, a connecting pipe 32 is arranged on the gas cylinder 31, and the connecting pipe 32 is provided with multiple groups of branch pipes 33, and the branch pipes 33 are all provided with connectors 331, and the connectors 331 are connected with the gas cylinder 31, and an electric pressure regulating valve 6 and a high-frequency solenoid valve 7 are arranged on the branch pipe 33, which are used to control the delivery of the gas medium in the gas cylinder 31;

[0027] At the same time, a premixing tank 4 is fixedly installed in the accommodating chamber 11 above the gas storage mechanism 3. The premixing tank 4 is provided with a pressure sensor 41. The pressure sensor 41 is used to help the premixing tank 4 monitor the pressure of the gas mixture. The premixing tank 4 is connected to the end of the connecting pipe 32 away from the gas storage bottle 31. At the same time, a vacuum pump 5 is provided on one side of the premixing tank 4. The vacuum pump 5 is connected to the premixing tank 4. When proportioning is required, the vacuum pump 5 is turned on to drive the gas in the gas storage bottle 31 to flow into the connecting pipe 32, and then enters the premixing tank 4 for mixing and proportioning after being screened by the electric pressure regulating valve 6 and the high-frequency solenoid valve 7;

[0028] At the same time, a gas storage tank 8 is detachably installed in the accommodating chamber 11 above the premixing tank 4. The gas storage tank 8 is provided with a quick-insert hose 81 on one side of the premixing tank 4. The quick-insert hose 81 is used to communicate with the premixing tank 4. At the same time, the other side of the gas storage tank 8 is connected to the vacuum pump 5. When the multiple gases in the premixing tank 4 are mixed, the gas in the premixing tank 4 can be driven by the vacuum pump 5 to flow into the gas storage tank 8;

[0029] Working principle: Before gas distribution, first use the vacuum pump 5 to evacuate the residual gas in the gas storage tank 8 and the premixing tank 4, then calculate the pressure of the three gases rushing into the various gases in the premixing tank 4 according to the ratio of the gases in the multiple groups of gas cylinders 31, and then gradually open the electric pressure regulating valves 6 of each gas source to fill the premixing tank 4 with gases of different pressures in turn to achieve gas matching. In this process, the pressure sensor 41 and the high-frequency solenoid valve 7 are interlocked and controlled. After the pressure is filled to the right level, the high-frequency solenoid valve 7 is automatically closed, so that the premixing tank 4 is filled with a variety of gases with different pressures and different media in turn to achieve the final matching ratio of the multiple gases.

[0030] like Figure 3-Figure 4 As shown, in order to make the connection between the gas cylinder 31 and the connecting pipe 32 more stable when the gas cylinder 31 operates in the accommodating chamber 11, improvements are made in the accommodating chamber 11, specifically:

[0031] A cylinder 12 is arranged in the accommodating cavity 11 at the bottom, and a base 13 is installed at the output end of the cylinder 12. The base 13 is provided with a plurality of mounting grooves 131 matching the size of the gas cylinder 31, and the mounting grooves 131 are located below the connector 331. When the gas cylinder 31 is installed, it is firmly mounted on the base 13 through the cooperation of the mounting grooves 131, and then the connector 331 can be connected to the gas cylinder 31.

[0032] Meanwhile, a protection component 9 is provided on the connector 331, and the protection component 9 includes a fixing plate 91, and the fixing plate 91 is fixedly mounted on the branch pipe 33. Meanwhile, a pressing plate 92 is provided at the bottom of the fixing plate 91, and a through hole 93 is provided at the center of the pressing plate 92, and the through hole 93 is suitable for the connector 331 to pass through;

[0033] At the same time, an elastic member 94 is provided between the fixed plate 91 and the pressing plate 92. One end of the elastic member 94 is fixedly mounted on the bottom of the fixed plate 91, and the other end is fixedly mounted on the top of the pressing plate 92. A plurality of guide rods 95 are also provided on the top of the pressing plate 92. One end of the guide rod 95 away from the pressing plate 92 penetrates the fixed plate 91 and is provided with a bolt 951. The guide rod 95 is used to guide the movement of the pressing plate 92, and the bolt 951 is used to prevent the guide rod 95 from completely separating from the pressing plate 92.

[0034] When the gas cylinder 31 is installed inside the base 13, the gas cylinder 31 is first connected to the connecting head 331, and then the cylinder 12 is controlled to drive the base 13 to move toward the connecting head 331. At this time, the pressure plate 92 will contact the opening of the gas cylinder 31. As the cylinder 12 moves, the elastic member 94 between the fixing plate 91 and the pressure plate 92 is gradually squeezed, and the reaction force formed is applied to the pressure plate 92, so that the gas cylinder 31 is firmly clamped between the pressure plate 92 and the base 13.

[0035] In summary, the device is provided with a protective component 9 so that the pressure plate 92 always applies pressure to the opening of the gas cylinder 31, so that the gas cylinder 31 is firmly clamped between the pressure plate 92 and the base 13, thereby ensuring that the gas cylinder 31 does not shake, thereby making the connection between the gas cylinder 31 and the connecting head 331 more stable, thereby increasing the practicality of the device.

[0036] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
