Description

Technical Field

[0001] This utility model belongs to the field of protective clothing technology, and in particular relates to an intelligent chemical protective suit with built-in temperature and humidity monitoring. Background Technology

[0002] Intelligent chemical protective clothing is a type of personal protective equipment used in high-risk chemical, biological, or radiation environments. Its core functions include: isolating harmful substances, preventing toxic gases, liquids, or particulate matter from contacting the human body, maintaining the internal microenvironment, providing breathing gas through compressed air cylinders, real-time monitoring, and integrating temperature, humidity, and pressure sensors to ensure the wearer's comfort and safety.

[0003] Existing intelligent chemical protective suits still have some problems during use, such as insufficient emergency ventilation, lack of rapid decompression mechanism when the internal air pressure is too high, which can easily lead to breathing difficulties for the wearer, reliance on manual judgment of environmental conditions, and inability to automatically adjust temperature, humidity and air pressure. To address these issues, we have provided an intelligent chemical protective suit with built-in temperature and humidity monitoring to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent chemical protective suit with built-in temperature and humidity monitoring. Through the cooperation of the exhaust valve mechanism and the overpressure exhaust mechanism, it solves the problem that existing intelligent chemical protective suits have insufficient emergency exhaust and lack a rapid decompression mechanism when the internal air pressure is too high, which can easily lead to breathing difficulties for the wearer.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to an intelligent chemical protective suit with built-in temperature and humidity monitoring. It includes an intelligent chemical protective suit body, a backpack connected to one side of the body, a compressed air cylinder fixedly connected inside the backpack, an intelligent monitoring component inside the body, and an exhaust valve mechanism on the top rear side of the body. The exhaust valve mechanism includes an exhaust pipe fixedly connected to the top rear side of the body, a first one-way valve connected to one end of the exhaust pipe, a drive component inside the exhaust pipe, and a sealing component inside the exhaust pipe. Overpressure exhaust mechanisms are provided on both the front and rear sides of the body. Each overpressure exhaust mechanism includes an overpressure valve pipe fixedly connected to the front and rear sides of the body, a second one-way valve connected to one end of the overpressure valve pipe, a magnetic suction component inside the overpressure valve pipe, and a sealing component inside the overpressure valve pipe.

[0007] The present invention is further configured such that the intelligent monitoring component includes a monitoring box fixedly connected inside the intelligent chemical protective suit body, a pressure sensor fixedly connected inside the monitoring box, a humidity sensor fixedly connected inside the monitoring box, and a temperature sensor fixedly connected inside the monitoring box. The number of intelligent monitoring components is two, respectively disposed on the front and rear sides of the intelligent chemical protective suit body.

[0008] The present invention is further configured such that the drive assembly includes a drive plate fixedly connected inside the exhaust pipe, and an electric push rod fixedly connected to one side of the drive plate.

[0009] The present invention is further configured such that the sealing assembly includes a sealing block fixedly connected to one side of the exhaust pipe, a sealing block disposed inside the sealing block, and a sealing plate fixedly connected to one side of the sealing block, wherein both the sealing block and the sealing block are funnel-shaped.

[0010] The present invention is further configured such that a sealing groove is provided at one end of both the exhaust pipe and the overpressure valve pipe, and a sealing strip is provided inside the sealing groove.

[0011] The present invention is further configured such that the magnetic attraction assembly includes a fixed plate fixedly connected inside the overpressure valve tube, an electromagnet fixedly connected to one side of the fixed plate, and a magnetic attraction rod magnetically attracted to the electromagnet.

[0012] The present invention is further configured such that the sealing assembly includes a compression spring disposed inside the overpressure valve tube, and a sealing plate fixedly connected to one end of the compression spring.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model achieves precise maintenance of a slightly positive pressure inside the chemical protective suit through the regulation of the exhaust valve mechanism. When the intelligent monitoring component detects that the air pressure exceeds the standard, the electric push rod is immediately activated, pushing the funnel-shaped sealing block to detach from the sealing block, forming an exhaust channel. The gas is discharged unidirectionally through the first one-way valve. After the air pressure returns to normal, the electric push rod retracts to reset the sealing block and seal it. This movement process, through the synergistic effect of electric drive and funnel-shaped sealing structure, ensures exhaust efficiency and prevents backflow of external pollutants, effectively improving the reliability of protection while maintaining a safe slightly positive pressure.

[0015] 2. The overpressure relief mechanism of this utility model achieves rapid response to emergency pressure relief through electromagnetic adsorption and spring linkage mechanism. When the air pressure exceeds the safety threshold, the electromagnet is de-energized and releases the magnetic rod. The compression spring extends instantly and pushes the sealing plate away from the valve port. The high-pressure gas is rapidly discharged through the second one-way valve. This structure effectively solves the defect of slow response of traditional safety valves and effectively prevents breathing difficulties caused by sudden rise in air pressure. At the same time, the alarm system linkage further ensures the timeliness of personnel evacuation.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1-5 This utility model is an intelligent chemical protective suit with built-in temperature and humidity monitoring. It includes an intelligent chemical protective suit body 1, a backpack 2 connected to one side of the intelligent chemical protective suit body 1, a compressed air cylinder fixedly connected inside the backpack 2, an intelligent monitoring component 3 installed inside the intelligent chemical protective suit body 1, an exhaust valve mechanism 4 installed on the top rear side of the intelligent chemical protective suit body 1, the exhaust valve mechanism 4 includes an exhaust pipe 41 fixedly connected to the top rear side of the intelligent chemical protective suit body 1, a first one-way valve 42 connected to one end of the exhaust pipe 41, a drive component 43 installed inside the exhaust pipe 41, and a sealing component 44 installed inside the exhaust pipe 41. Both the front and rear sides of the intelligent chemical protective suit body 1 are provided with overpressure exhaust mechanisms 5. The overpressure exhaust mechanism 5 includes an overpressure valve pipe 51 fixedly connected to the front and rear sides of the intelligent chemical protective suit body 1, a second one-way valve 52 connected to one end of the overpressure valve pipe 51, a magnetic suction component 53 installed inside the overpressure valve pipe 51, and a sealing component 54 installed inside the overpressure valve pipe 51.

[0027] Specifically: The exhaust valve mechanism 4 is used to maintain a slightly positive pressure environment inside the chemical protective suit, ensuring one-way gas discharge and preventing external contaminants from entering. When the internal air pressure exceeds the set value, the electric push rod 432 is activated, pushing the funnel-shaped sealing block 442 out of the sealing block 441 to form an exhaust channel. Gas is discharged through the exhaust pipe 41 and the first one-way valve 42. When the pressure is normal and no pressure relief is needed, the electric push rod 432 retracts, causing the sealing block 442 to reset and fit tightly against the sealing block 441, blocking gas flow. The sealing plate 443 and the sealing strip 6 further prevent leakage. By setting up the overpressure exhaust mechanism 5, the pressure can be quickly released when the air pressure is too high, avoiding breathing difficulties for the wearer. When the internal air pressure exceeds the safety threshold, the electromagnet 532 is de-energized, the magnetic rod 533 separates from the sealing plate 542, the compression spring 541 extends, and pushes the sealing plate 542 away from the outlet of the overpressure valve pipe 51. The gas is quickly discharged through the second one-way valve 52. At the same time, the alarm device inside the intelligent chemical protective suit body 1 sounds an alarm to remind personnel to evacuate quickly. During the evacuation, personnel can manually press the sealing plate 542 to reset, so that the electromagnet 532 and the magnetic rod 533 can be magnetically sealed again.

[0028] Example 2

[0029] Please see Figures 1-5Based on Embodiment 1, the intelligent monitoring component 3 includes a monitoring box fixedly connected inside the intelligent chemical protective suit body 1, a pressure sensor fixedly connected inside the monitoring box, a humidity sensor fixedly connected inside the monitoring box, and a temperature sensor fixedly connected inside the monitoring box. There are two intelligent monitoring components 3, respectively located on the front and rear sides of the intelligent chemical protective suit body 1. The drive component 43 includes a drive plate 431 fixedly connected inside the exhaust pipe 41, and an electric push rod 432 fixedly connected to one side of the drive plate 431. The sealing component 44 includes a sealing block 441 fixedly connected to one side of the exhaust pipe 41, a sealing block 442 located inside the sealing block 441, and a sealing plate 443 fixedly connected to one side of the sealing block 442. Both the sealing block 441 and the plugging block 442 are funnel-shaped. One side of the plugging block 442 is fixedly connected to the output end of the electric push rod 432. Both the exhaust pipe 41 and the overpressure valve pipe 51 have a sealing groove at one end. A sealing strip 6 is provided inside the sealing groove. The magnetic attraction component 53 includes a fixing plate 531 fixedly connected inside the overpressure valve pipe 51, an electromagnet 532 fixedly connected to one side of the fixing plate 531, and a magnetic attraction rod 533 magnetically attracted to the electromagnet 532. The sealing component 54 includes a compression spring 541 set inside the overpressure valve pipe 51, and a sealing plate 542 fixedly connected to one end of the compression spring 541. The other end of the compression spring 541 is fixedly connected to the fixing plate 531, and the other end of the magnetic attraction rod 533 is fixedly connected to the sealing plate 542.

[0030] Specifically: The intelligent monitoring component 3 is used to monitor the pressure, temperature, and humidity inside the intelligent chemical protective suit body 1. The drive component 43 is used to move the sealing block 442 out of the interior of the sealing block 441 when venting is required, forming an venting channel to allow the gas inside the intelligent chemical protective suit body 1 to be discharged smoothly. When venting is not required, the sealing block 442 is reset. The sealing component 44 is used to seal the exhaust end of the exhaust pipe 41. The sealing strip 6 is used to seal the exhaust end of the exhaust pipe 41 and the overpressure valve pipe 51. The magnetic suction component 53 is used to magnetically fix the sealing plate 542 when the pressure is stable and emergency pressure relief is not required. The sealing component 54 is used to seal the exhaust end of the overpressure valve pipe 51. When the pressure is too high and emergency pressure relief is required, the electromagnet 532 is de-energized and the compression spring 541 extends to push the sealing plate 542 out, quickly relieving pressure.

[0031] The working principle of this utility model is as follows: The exhaust valve mechanism 4 monitors the internal air pressure of the chemical protective suit in real time through the intelligent monitoring component 3. When the air pressure exceeds the set threshold, the control system activates the electric push rod 432, which pushes the funnel-shaped sealing block 442 out of the sealing block 441 to form an exhaust channel. The internal gas is discharged in one direction through the exhaust pipe 41 and the first one-way valve 42, ensuring that external pollutants cannot invade in the reverse direction. When the air pressure returns to normal, the electric push rod 432 retracts, which drives the sealing block 442 to reset and fit tightly with the sealing block 441, blocking the gas flow. The sealing plate 443 and the sealing strip 6 work together to further ensure the sealing performance and maintain the micro-positive pressure environment inside the chemical protective suit.

[0032] The overpressure exhaust mechanism 5 acts as a safety valve, activating emergency pressure relief when the air pressure rises abnormally. When the intelligent monitoring component 3 detects that the air pressure exceeds the safety threshold, the control system cuts off the power to the electromagnet 532, the magnetic rod 533 separates from the sealing plate 542, and the compression spring 541 extends, pushing the sealing plate 542 away from the outlet of the overpressure valve pipe 51. The internal high-pressure gas is quickly discharged through the second one-way valve 52. If the overpressure exhaust mechanism 5 is activated, it indicates that the exhaust valve mechanism 4 cannot exhaust normally. At this time, the alarm device inside the intelligent chemical protective suit body 1 sounds an alarm, reminding personnel to evacuate quickly.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
