Description

Technical Field

[0001] This invention relates to the field of detection technology, and in particular to a pressure relief detection device. Background Technology

[0002] In conventional liquid or gas pipelines, information about whether liquid or gas is being ejected from the outlet or gas nozzle is typically obtained through liquid flow or pressure detection devices. However, these methods require the detection device to have ample internal space to accommodate pressure or flow rate sensors, resulting in high costs. Furthermore, because the detection is indirect, it does not accurately reflect the state of the outlet or gas nozzle. Summary of the Invention

[0003] The main objective of this invention is to provide a pressure relief detection device that accurately reflects the precise status of a water outlet or gas nozzle, thereby reducing costs.

[0004] To achieve the above objectives, the pressure relief detection device proposed in this invention includes:

[0005] A fluid conduit having a fluid nozzle for ejecting fluid;

[0006] A signal generating structure having a pressure-bearing section that is easily interrupted by the fluid ejected from the fluid nozzle, the pressure-bearing section being disposed opposite to the fluid nozzle; and

[0007] The monitor is electrically connected to the signal generating structure;

[0008] When the pressure-bearing section is interrupted by the fluid ejected from the fluid nozzle, the internal circuit of the signal generating structure generates a feedback signal along with the breakage of the pressure-bearing section and sends it to the monitor to obtain the ejection status of the fluid nozzle.

[0009] In one embodiment, the signal generating structure further includes a first fixing section connected to the pressure-bearing section. The first fixing section is provided with a first fixing bracket for connecting to an external connector, which can fix the pressure-bearing section at the fluid nozzle.

[0010] In one embodiment, the signal generating structure further includes a second fixing section, which is connected to the side of the pressure-bearing section away from the first fixing section. The second fixing section is provided with a second fixing bracket, which is used to connect with an external connector and can fix the pressure-bearing section at the fluid nozzle.

[0011] In one embodiment, the pressure-bearing section is connected to the first fixed section via a first fracture portion, and the pressure-bearing section is connected to the second fixed section via a second fracture portion;

[0012] When the first fracture section breaks, the pressure-bearing section separates from the first fixed section; when the second fracture section breaks, the pressure-bearing section separates from the second fixed section.

[0013] In one embodiment, the thickness of the first fracture portion and the second fracture portion along the fluid nozzle injection direction is less than the thickness of the pressure-bearing section, the first fixing section, and the second fixing section.

[0014] In one embodiment, the first fracture portion is provided as a notch, and the longitudinal section of the notch is provided as a triangle.

[0015] In one embodiment, the first fracture portion is provided with a plurality of hollow holes, which are arranged at intervals along the width direction of the pressure-bearing section.

[0016] In one embodiment, the signal generating structure includes a carrier and a circuit conductor, the circuit conductor being disposed inside the carrier and connected to the monitor, and the pressure-bearing section being formed by combining a portion of the circuit conductor and a portion of the carrier;

[0017] When the pressure-bearing section is broken by the fluid ejected from the fluid nozzle, the circuit conductor breaks along with the pressure-bearing section and generates a feedback signal that is sent to the monitor to obtain the ejection status of the fluid nozzle.

[0018] In one embodiment, the carrier is a PCB, and the circuit conductor is copper foil on the PCB;

[0019] Alternatively, the carrier may be made of an insulating material, and the circuit conductor may be disposed on the insulating material.

[0020] In one embodiment, the fluid pipeline is connected to a pressure vessel for holding fluid; a main body mounting bracket is also provided on the first fixed section and / or the second fixed section, and the main body mounting bracket is fixedly connected to the pressure vessel.

[0021] This invention employs a pressure relief detection device comprising a fluid pipeline, a signal generating structure, and a monitor. The fluid pipeline has a fluid nozzle for ejecting fluid. The signal generating structure has a pressure-bearing section that is easily broken by the fluid ejected from the nozzle, and the pressure-bearing section is positioned opposite the fluid nozzle. The monitor is electrically connected to the signal generating structure. When the pressure-bearing section is broken by the fluid ejected from the nozzle, the internal circuit of the signal generating structure breaks along with the pressure-bearing section and generates a feedback signal, which is sent to the monitor to obtain the ejection state of the fluid nozzle. With this configuration, when liquid or gas is ejected from the nozzle, the liquid or gas directly exerts pressure on the pressure-bearing section. Upon being subjected to the pressure of the liquid or gas, the pressure-bearing section breaks, and the internal circuitry of the pressure-bearing section disconnects. This disconnection causes a change in the electrical signal of the circuitry within the signal generating structure, thereby generating a breakage feedback signal that is transmitted to the monitor to achieve the detection purpose. The detection device is low-cost, provides direct detection, improves detection accuracy, and avoids detection errors. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure).

Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0038] In conventional liquid or gas pipelines, information about whether liquid or gas is being ejected from the outlet or gas nozzle is typically obtained through liquid flow or pressure detection devices. However, these methods require the detection device to have ample internal space to accommodate pressure or flow rate sensors, resulting in high costs. Furthermore, because the detection is indirect, it does not accurately reflect the state of the outlet or gas nozzle.

[0039] Please see Figures 1 to 8 This invention proposes a pressure relief detection device.

[0040] The pressure relief detection device includes a fluid pipeline 100, a signal generating structure 200, and a monitor 300. The fluid pipeline 100 has a fluid nozzle 110 for ejecting fluid. The signal generating structure 200 has a pressure-bearing section 230 that is easily broken by the fluid ejected from the fluid nozzle 110. The pressure-bearing section 230 is arranged opposite to the fluid nozzle 110. The monitor 300 is electrically connected to the signal generating structure 200. When the pressure-bearing section 230 is broken by the fluid ejected from the fluid nozzle 110, the internal circuit of the signal generating structure 200 breaks along with the pressure-bearing section 230 and generates a feedback signal, which is sent to the monitor 300 to obtain the ejection state of the fluid nozzle 110.

[0041] Specifically, fluid conduit 100 can be a liquid conduit or a gas conduit; the fluid can be either liquid or gas; when fluid conduit 100 is a liquid conduit, the fluid is liquid; when fluid conduit 100 is a gas conduit, the fluid is gas. The spraying state of fluid nozzle 110 refers to detecting whether fluid is being ejected from fluid nozzle 110. The distance between fluid nozzle 110 and pressure-bearing section 230 can be 0 or greater than 0. When the distance between fluid nozzle 110 and pressure-bearing section 230 is 0, fluid nozzle 110 is in contact with pressure-bearing section 230, and the fluid directly breaks the pressure-bearing section 230, generating a feedback signal to monitor 300. Monitor 300 then determines that fluid nozzle 110 has ejected liquid or gas. The pressure-bearing section 230 contains a circuit portion of the signal generating structure 200. When liquid or gas is ejected from the fluid nozzle 110, the liquid or gas directly exerts pressure on the pressure-bearing section 230. Upon being subjected to the pressure of the liquid or gas, the pressure-bearing section 230 breaks. This breakage disconnects the circuit portion inside the pressure-bearing section 230, causing a change in the electrical signal within the signal generating structure 200, thereby generating a breakage feedback signal that is transmitted to the monitor for detection. This design results in a low-cost, direct detection method with improved accuracy, avoiding detection errors.

[0042] Please see Figures 1 to 6 In one embodiment, the signal generating structure 200 further includes a first fixing section 210 connected to the pressure-bearing section 230. A first fixing bracket 211 is provided on the first fixing section 210, which is used to connect to an external connector to fix the pressure-bearing section 230 at the fluid nozzle 110. It is understood that the external connector can be a wall or other device, as long as it serves to fix the first fixing section 210. When liquid or gas is ejected from the fluid nozzle 110, the first fixing section 210 remains stationary, while the pressure-bearing section 230 is broken by the fluid, separating from the first fixing section 210.

[0043] Please see Figure 1 In one embodiment, the signal generating structure 200 further includes a second fixing segment 220, which is connected to the side of the pressure-bearing segment 230 away from the first fixing segment 210. A second fixing bracket 221 is provided on the second fixing segment 220, which is used to connect to an external connector and fix the pressure-bearing segment 230 at the fluid nozzle 110. It is understood that the external connector can be a wall or other device, as long as it serves to fix the second fixing segment 220. In this embodiment, when liquid or gas is ejected from the fluid nozzle 110, the first fixing segment 210 and the second fixing segment 220 remain stationary. The pressure-bearing segment 230 is broken by the fluid, separating from the first fixing segment 210 and the second fixing segment 220 on both sides, causing circuit damage and generating a feedback signal.

[0044] Please see Figures 1 to 6 In one embodiment, the pressure-bearing section 230 is connected to the first fixed section 210 via a first fracture portion 231, and the pressure-bearing section 230 is connected to the second fixed section 220 via a second fracture portion 224. When the first fracture portion 231 breaks, the pressure-bearing section 230 separates from the first fixed section 210; when the second fracture portion 224 breaks, the pressure-bearing section 230 separates from the second fixed section 220. It is understood that the first fracture portion 231 and the second fracture portion 224 are easily fractured structures, and their materials should be configured such that the pressure generated when the fluid nozzle 110 ejects liquid or gas is sufficient to cause the first fracture portion 231 and the second fracture portion 224 to fracture, thereby separating the pressure-bearing section 230 from the first fixed section 210 and the second fixed section 220.

[0045] Please see Figure 1In one embodiment, the thickness of the first fracture portion 231 and the second fracture portion 224 along the injection direction of the fluid nozzle 110 is less than the thickness of the pressure-bearing section 230, the first fixing section 210, and the second fixing section 220. By reducing the thickness of the first fracture portion 231 and the second fracture portion 224, the pressure-bearing capacity of the first fracture portion 231 and the second fracture portion 224 is reduced, making it easier for the pressure-bearing section 230 to break, thereby altering the internal circuitry of the signal generating structure 200.

[0046] Please see Figure 3 In one embodiment, the first fracture portion 231 is provided as a notch 233, and the longitudinal section of the notch 233 is triangular. When liquid or gas is ejected from the fluid nozzle 110, the pressure-bearing section 230 breaks from the notch 233, causing the pressure-bearing section 230 to break apart. Of course, in other embodiments, the longitudinal section of the notch 233 can also be a regular shape such as a quadrilateral or a pentagon, or an irregular shape.

[0047] Please see Figure 4 In one embodiment, the first fracture portion 231 is provided with a plurality of perforated holes 232, which are arranged at intervals along the width direction of the pressure-bearing section 230. The shape of the perforated holes 232 can be rectangular, triangular, circular, etc. In a preferred embodiment, the perforated holes 232 are rectangular. By providing perforated holes 232, the pressure-bearing capacity of the first fracture portion 231 can be reduced.

[0048] Please see Figures 2 to 4 In one embodiment, the signal generating structure 200 includes a carrier 240 and a circuit conductor 250. The circuit conductor 250 is disposed inside the carrier 240 and connected to the monitor 300. The pressure-bearing section 230 is formed by combining a portion of the circuit conductor 250 and a portion of the carrier 240. When the pressure-bearing section 230 is broken by the fluid ejected from the fluid nozzle 110, the circuit conductor 250 breaks along with the pressure-bearing section 230 and generates a feedback signal sent to the monitor 300 to obtain the ejection state of the fluid nozzle 110. It is understood that, as Figures 7 to 8As shown, when the signal generating structure 200 is intact, the circuit conductor 250 extends into the carrier 240, and the pressure-bearing section 230 is part of both the circuit conductor 250 and the carrier 240. In this circuit diagram, the detection circuit receives a low level. After the signal generating structure 200 is broken, the circuit conductor 250 also breaks along with the pressure-bearing section 230. In this circuit diagram, the detection circuit receives a high level, causing a change in the electrical signal within the circuit of the circuit conductor 250. When the circuit is in a non-triggered state, i.e., when the circuit conductor 250 is intact, it acts as a normally closed contact. When the pressure-bearing section 230 breaks under pressure, the circuit conductor 250 breaks along with it, causing the circuit state to change from normally closed to normally open. This generates a feedback signal from the fluid nozzle 110, which is essentially a dry contact signal. This feedback signal is sent to the monitor. In this embodiment, the circuit conductor 250 can be connected in series with a resistor or can be a direct path, depending on the actual situation.

[0049] In one embodiment, the carrier 240 is a PCB, and the circuit conductor 250 is copper foil on the PCB; alternatively, the carrier 240 is made of an insulating material, and the circuit conductor 250 is disposed on the insulating material. The circuit conductor 250 can be copper foil on the PCB or other conductors. The circuit conductor 250 can be inside the insulating material or placed outside the insulating material after sufficient consideration of insulation. For ease of breakage, it can be made of an easily breakable material, thereby more easily meeting the requirement that the circuit conductor 250 breaks due to the fracture of the pressure-bearing section 230.

[0050] Please see Figures 5 to 6 In one embodiment, the fluid pipeline 100 is connected to a pressure vessel 700, which is used to hold fluid. A main mounting bracket 230 is also provided on the first fixed section 210 and / or the second fixed section 220, and the main mounting bracket 230 is fixedly connected to the pressure vessel 700. It is understood that the pressure vessel 700 can be integrated with the signal generating structure 200 or it can be separate from the signal generating structure 200. In other embodiments, the detection device does not have a main mounting bracket 230. The pressure in the pressure vessel 700 comes from a liquid pump, a pneumatic pump, or other gas or gas generating device, serving as a power source for the liquid or gas.
