Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, and in particular to a gas detection and diversion mechanism. Background Technology

[0002] With the increasing emphasis on ozone applications in environmental monitoring, industrial process control, and medical disinfection, the demand for stable and precise ozone supply and distribution is also gradually increasing. Traditional gas diversion methods typically employ simple pipe branch structures. While this method is simple in construction, in practical use, due to the lack of appropriate buffer components, pressure changes in the input gas are directly transmitted to each branch. If the gas pressure suddenly increases, it can cause instability in the operation of downstream equipment. Utility Model Content

[0003] To address the technical problem that existing gas diversion mechanisms lack suitable buffer components, causing pressure changes in the input gas to be directly transmitted to each branch, and resulting in unstable operation of downstream equipment if the gas pressure suddenly increases, this invention provides a gas detection and diversion mechanism.

[0004] The technical solution adopted in this utility model is:

[0005] A gas detection and diversion mechanism includes a buffer housing, an inlet pipe, a first outlet pipe, and a second outlet pipe. One side of the buffer housing is connected to one end of the inlet pipe, and the other side of the buffer housing is connected to one end of the first outlet pipe and one end of the second outlet pipe.

[0006] The buffer box is equipped with a flow-diverting buffer assembly, which includes a first plate, a second plate, a third plate, and an elastic element. The first plate and the second plate are respectively connected to the inner sidewall of the buffer box and are arranged opposite to each other. The third plate is disposed between the first plate and the second plate and is arranged opposite to the air intake pipe. One end of the elastic element is connected to the sidewall of the third plate, and the other end of the elastic element is connected to the inner sidewall of the buffer box.

[0007] The third plate, the first plate, and the inner wall of the buffer box form a first gas channel, and the third plate, the second plate, and the inner wall of the buffer box form a second gas channel. The first gas outlet pipe is connected to the first gas channel, and the second gas outlet pipe is connected to the second gas channel.

[0008] Preferably, the top of the third plate is slidably connected to the first plate, and the bottom of the third plate is slidably connected to the second plate.

[0009] Preferably, the first plate is provided with a first sliding groove, the second plate is provided with a second sliding groove, the top of the plate is slidably connected to the first sliding groove, and the bottom of the second plate is slidably connected to the second sliding groove.

[0010] Preferably, the first plate is provided with a plurality of first through holes, and the second plate is provided with a plurality of second through holes. One end of the first through hole is connected to the first gas channel, and the other end of the first through hole is connected to the first sliding groove; one end of the second through hole is connected to the second gas channel, and the other end of the second through hole is connected to the second sliding groove.

[0011] Preferably, the first plate, the second plate, the third plate, and the inner wall of the buffer box form a buffer chamber. A partition is provided in the buffer chamber. One end of the partition is connected to the side wall of the third plate, and the other end of the partition is connected to the inner wall of the buffer box. The partition divides the buffer chamber into a first buffer chamber and a second buffer chamber. The first buffer chamber communicates with the first through hole, and the second buffer chamber communicates with the second through hole.

[0012] Preferably, the separator includes a fixed part and a sliding part. One end of the fixed part is connected to the inner wall of the buffer box. The fixed part is hollow inside. The other end of the fixed part is an opening. One end of the sliding part is slidably connected to the inner wall of the fixed part. The other end of the sliding part is connected to the side wall of the third plate.

[0013] Preferably, the length of the sliding part is less than the internal length of the fixed part.

[0014] Preferably, a first flow valve is provided at the other end of the first outlet pipe, and the other end of the first outlet pipe is used to connect to an ozone generating device. A second flow valve is provided at the other end of the second outlet pipe, and the other end of the second outlet pipe is used to connect to a device to be calibrated.

[0015] The beneficial effects of this invention are as follows: When the third plate in the diversion buffer assembly is impacted by airflow, it moves towards the inner wall of the buffer housing opposite to the intake pipe. At this time, the elastic element is compressed, effectively absorbing and buffering pressure fluctuations in the intake pipe. When the gas pressure in the intake pipe suddenly increases, the movement of the third plate and the compression of the elastic element reduce the impact of pressure fluctuations on the downstream first and second exhaust pipes, ensuring the stability of gas output.

[0025] Example 1

[0026] like Figure 1 As shown, a gas detection and diversion mechanism includes a buffer box, an inlet pipe, a first outlet pipe, and a second outlet pipe. One side of the buffer box is connected to one end of the inlet pipe, and the other side of the buffer box is connected to one end of the first outlet pipe and one end of the second outlet pipe. A diversion buffer assembly is disposed inside the buffer box. The diversion buffer assembly includes a first plate, a second plate, a third plate, and an elastic element. The first plate and the second plate are respectively connected to the inner sidewall of the buffer box and are arranged opposite to each other. The third plate is disposed between the first plate and the second plate and is arranged opposite to the inlet pipe. One end of the elastic element is connected to the sidewall of the third plate, and the other end of the elastic element is connected to the inner sidewall of the buffer box. The third plate, the first plate, and the inner wall of the buffer box form a first gas channel, and the third plate, the second plate, and the inner wall of the buffer box form a second gas channel. The first outlet pipe is connected to the first gas channel, and the second outlet pipe is connected to the second gas channel.

[0027] For reference, the elastic element can be a spring. For example... Figure 2 As shown, in one possible implementation, the top of the third plate is slidably connected to the first plate, and the bottom of the third plate is slidably connected to the second plate. Referencely, the first plate has a first groove, the second plate has a second groove, the top of the plate is slidably connected to the first groove, and the bottom of the second plate is slidably connected to the second groove.

[0028] In this embodiment, when gas enters the buffer chamber from the intake pipe, the gas impacts the third plate, causing it to move towards the inner wall of the buffer chamber on the side opposite to the intake pipe. At this time, the elastic element is compressed, thereby absorbing and buffering the pressure fluctuations of the gas. As gas continues to flow in, the third plate gradually returns to its original position under the elastic force of the elastic element. Simultaneously, the gas is diverted into the first gas channel and the second gas channel, and output through the first exhaust pipe and the second exhaust pipe, respectively.

[0029] Example 2

[0030] like Figure 3 As shown, in one possible implementation, the first plate is provided with a plurality of first through holes, and the second plate is provided with a plurality of second through holes. One end of the first through hole is connected to the first gas channel, and the other end of the first through hole is connected to the first sliding groove; one end of the second through hole is connected to the second gas channel, and the other end of the second through hole is connected to the second sliding groove.

[0031] In this embodiment, when gas enters the buffer chamber from the intake pipe, the gas impacts the third plate. Since the third plate is positioned opposite the intake pipe and supported by an elastic element, the gas is initially diverted into the first and second gas channels under the action of the third plate. With continued gas impact, the third plate slides on the first and second slide grooves under the elastic force of the elastic element. This sliding process gradually exposes the first and second through holes, allowing more gas to enter the first gas channel through the first through hole and the second gas channel through the second through hole. This helps prevent gas from remaining in the chamber formed by the third plate, the inner wall of the buffer chamber, the second plate, and the first plate.

[0032] Example 3

[0033] like Figure 4 As shown, in one possible implementation, the first plate, the second plate, the third plate, and the inner wall of the buffer box form a buffer chamber. A partition is provided in the buffer chamber. One end of the partition is connected to the side wall of the third plate, and the other end of the partition is connected to the inner wall of the buffer box. The partition divides the buffer chamber into a first buffer chamber and a second buffer chamber. The first buffer chamber communicates with the first through hole, and the second buffer chamber communicates with the second through hole.

[0034] like Figure 4 As shown, illustratively, the separator includes a fixed part and a sliding part. One end of the fixed part is connected to the inner wall of the buffer box, and the fixed part is hollow. The other end of the fixed part is an opening. One end of the sliding part is slidably connected to the inner wall of the fixed part, and the other end of the sliding part is connected to the side wall of the third plate. Illustratively, the length of the sliding part is less than the internal length of the fixed part.

[0035] In this embodiment, when gas from the intake pipe enters the buffer chamber, it first impacts the third plate. Supported by the elastic element, the third plate moves, altering the opening degree of the first and second through holes, thus achieving initial gas diversion. Simultaneously, the partition divides the buffer chamber into a first buffer chamber and a second buffer chamber. Since the sliding part is connected to the third plate and can slide within the fixed part, the partition moves along with the third plate, further adjusting the volume of the first and second buffer chambers. The partition ensures that the gas, after entering the buffer chamber, can be more evenly distributed into the two independent chambers, preventing gas that should enter the first gas channel from entering the second gas channel through the buffer chamber, and vice versa.

[0036] For reference, such as Figure 4 As shown, a first flow valve is installed at the other end of the first outlet pipe, which is used to connect to an ozone generator. A second flow valve is installed at the other end of the second outlet pipe, which is used to connect to the device to be calibrated. The first and second flow valves further regulate and control the gas flow in these two channels to meet the needs of different devices.

[0037] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
