[0033] Please refer to Figures 1-7 As shown, one embodiment of this application provides a ventilated airsuit, which includes a torso 10, a head covering 20, two arm parts 30, and two leg parts 40. The torso 10, head covering 20, two arm parts 30, and two leg parts 40 form the shape of a human body and have a cavity for accommodating the human body. The head covering 20 is located above the torso 10 and is used to accommodate the head of the human body. The two arm parts 30 are respectively connected to the upper end of the torso 10 and are used to accommodate the arms of the human body. The two leg parts 40 are respectively connected to the lower end of the torso 10 and are used to accommodate the legs and feet of the human body. The torso 10 has a back 11 with a single-layer zipper 12 extending from the side near the leg parts 40 toward the head covering 20. The length of the single-layer zipper 12 is at least 2 / 3 of the height of the entire ventilated airsuit, thereby facilitating the user to put on the ventilated airsuit. The headgear 20 is a cavity component, with continuous transparent viewing window areas 21 on its front surface and two adjacent side surfaces. The viewing angle formed between the transparent viewing window areas 21 and the human eye is within the range of 110°-190°. The headgear 20 has a central axis, and the angle formed between the two side edges of the transparent viewing window areas 21 and the central axis is within the range of 55°-95°. This structure allows the viewing angle formed between the transparent viewing window areas 21 and the human eye to be controlled within the range of 110°-190°, thereby improving the user's field of vision.

[0034] In an optional embodiment, the ventilated jacket further includes an air delivery assembly 50 and an air regulating valve 60. The air delivery assembly 50 includes a waist channel 51, two arm channels 30, two leg channels 53, and a first airflow pipe. The first airflow pipe is disposed in the waist channel 51, and the air regulating valve 60 is mounted on the first airflow pipe.

[0035] Specifically, the ventilated airsuit also includes an air regulating valve 60 and an air delivery assembly 50. The air regulating valve 60 is installed at the outer end of the first airflow duct and protrudes from the ventilated airsuit to facilitate the connection of external air hoses. The first airflow duct is located within the waist channel 51 and extends into the waist channel 51 to deliver airflow into the two arm channels 30 and the two leg channels 53, thereby facilitating the filling of the entire ventilated airsuit with gas to ensure that the pressure inside the ventilated airsuit is adapted to human comfort and increase the worker's work comfort.

[0036] In an optional embodiment, the ventilated jacket further includes a second airflow duct 70 and an alarm 80, the alarm 80 being located inside the headgear 20, with one end of the second airflow duct 70 connected to an air regulating valve 60 and the other end connected to the alarm 80.

[0037] Specifically, the ventilated airsuit also includes an alarm 80 and a second airflow pipe 70. One end of the second airflow pipe 70 is connected to the air regulating valve 60, and the other end is connected to the alarm 80. The second airflow pipe 70 passes through the waist passage 51 from one side of the air regulating valve 60 and extends into the headgear 20, connecting to the alarm 80 located inside the headgear 20 for direct observation by the worker. The alarm 80 is used to report the air pressure delivered to the inside of the ventilated airsuit from the external air supply pipe. If the air pressure in the external pipe is lower than the normal value, the alarm 80 will turn red, prompting the worker to move away immediately to avoid suffocation. It should be noted that the normal air pressure value here is usually set to 60 kg.

[0038] The ventilated airsuit also includes a first tear strip 90, which extends from one arm 30 to the other arm 30 and passes through the headgear 20. The first tear strip 90 is welded to the arm 30 and the headgear 20. In this embodiment, the first tear strip 90 is directly welded to the arm 30 and the headgear 20 using high-frequency welding. The first tear strip 90 is used to tear open in an emergency, allowing the user to breathe outside air. In an emergency, such as when the external air supply pipeline is blocked, preventing the worker from breathing, the worker needs to immediately tear off the first tear strip 90 to breathe. Related solutions on the market involve using a connecting strap, first connecting the connecting strap to the ventilated airsuit, and then welding the tear strip to the connecting strap, thus connecting the tear strip to the arm 30 of the ventilated airsuit. This solution has a complex manufacturing process, requiring two welding operations. This application only requires one welding operation to weld the first tear strip 90 to the arm 30 and the headgear 20.

[0039] In an optional embodiment, the first tear strip 90 forms two weld lines along its length, with the distance between the two weld lines ranging from 1 to 4 mm. The first tear strip 90 of this application is welded along its length, and two spaced weld lines are formed on the first tear strip 90. This application reduces the force required for the operator to tear the first tear strip 90 by controlling the distance between the two weld lines, thus avoiding situations where the operator is unable to tear it due to tension in an emergency.

[0040] In an optional embodiment, the lower end of the leg section 40 has a shoe cover strap 41 for securing the leg section 40 at the ankle position corresponding to the human body. The worker's entire body is contained within the ventilated airsuit of this application. Since the airsuit is relatively long, it is inconvenient for the worker to move. This application provides a shoe cover strap 41 at the lower part of the leg section 40 to secure the ankle position, making it easier for the user to move while wearing the ventilated airsuit. This facilitates the worker's work, improves work efficiency, and increases work accuracy.

[0041] In an optional embodiment, the leg and foot section 40 is provided with thickened portions at the knee, groin, and elbow positions corresponding to the human body. The leg and foot section 40 also has a thickened shoe cover 42 at the foot position. This application thickens areas subject to frequent friction, improving the abrasion resistance of the ventilated air-cushioned clothing. Furthermore, this application only increases the thickness at the knee, groin, and elbow positions, without increasing the thickness of the two air-cushioned clothing sections. Therefore, within a suitable range for user use, the abrasion resistance of the ventilated air-cushioned clothing can be improved, reducing the probability of it being worn through.

[0042] In an optional embodiment, the ventilated airsuit of this application further includes a first exhaust valve 100 disposed on the headgear 20 and a second exhaust valve 110 disposed on the back 11 of the body part 10. And / or, the surface of the second exhaust valve 110 is printed with an instruction manual and a relevant information filling area.

[0043] This application provides a first exhaust valve 100 at the top of the headgear 20 and a second exhaust valve 110 on the back 11 of the body part 10. Both the first exhaust valve 100 and the second exhaust valve 110 are one-way valves, which can be used to allow airflow from inside the ventilated airsuit to the outside. When in use, the ventilated airsuit is continuously supplied with air from the outside high-pressure gas to fill it with air. Under the action of the first exhaust valve 100 and the second exhaust valve 110, the internal air can be exhausted to the outside of the ventilated airsuit, thus providing uninterrupted air supply to the worker.

[0044] In an optional embodiment, the alarm 80 includes a housing 81, a warning element 82, and a resilient element 83. The housing 81 has a receiving cavity inside, and its lower end has an air inlet 81aa for air intake. The warning element 82 is movably disposed within the receiving cavity. The resilient element 83 is disposed within the receiving cavity, with one end abutting against the warning element 82 and the other end abutting against the end of the housing 81 away from the air inlet 81aa. The lower end of the housing 81 has a transparent area, and the warning element 82 is used to move within the receiving cavity under the action of air intake pressure, moving into or out of the transparent area for user viewing.

[0045] Specifically, the alarm 80 of this application is installed inside the air hood of a ventilation hood for observation by the user in a contaminated area. The housing 81 has an internal cavity for accommodating a warning element 82. The warning element 82 is disposed within the cavity, and one end of an elastic member 83 abuts against the warning element 82, while the other end abuts against the bottom wall of the upper end of the cavity. The lower end of the housing 81 has an air inlet 81aa that communicates with the cavity, allowing external air to enter the cavity and contact the warning element 82, thereby moving the warning element 82 within the cavity.

[0046] During use, an external air pipe is connected to the air inlet 81aa at the lower end of the housing 81 via a connecting pipe to deliver breathable air to the alarm 80. Under gas pressure, the warning element 82 compresses the elastic element 83, causing the warning element 82 to move outside the transparent area. If the user cannot see the warning element 82 when observing the transparent area, it indicates that the external gas pressure is sufficient, providing enough breathing air for the operator. Alternatively, if the external gas supply is insufficient, the elasticity of the elastic element 83 exceeds the gas pressure, causing the elastic element 83 to push the warning element 82 into the transparent area. The user can then directly observe the warning element 82 through the transparent area. In this case, the operator must immediately leave the contaminated environment to prevent danger from insufficient air supply.

[0047] It should be noted that the warning element 82 is a bright color to distinguish it from the transparent element, allowing operators to easily confirm whether the gas supply is sufficient. In some optional embodiments, the warning element 82 is red to facilitate alerting operators.

[0048] In an optional embodiment, the housing 81 includes a lower cylinder 811 and an upper cylinder 812, which are assembled to form a receiving cavity. The inner wall of the upper cylinder 812 has internal threads, a portion of the lower cylinder 811 extends into the upper cylinder 812, and the portion extending into the upper cylinder 812 has external threads adapted to the internal threads.

[0049] Specifically, the housing 81 is assembled from two lower cylinders 811. An upper cylinder 812 is fitted over a portion of the upper end of the lower cylinder 811, allowing other parts of the lower cylinder 811 to be exposed. The upper cylinder 812 and the lower cylinder 811 are secured by internal and external threads. The upper cylinder 812 is opaque, while a transparent area is located on the lower cylinder 811. When the upper cylinder 812 and lower cylinder 811 are assembled as a single unit, a portion of the lower cylinder 811 is located outside the upper cylinder 812, allowing the transparent area on the lower cylinder 811 to be exposed for viewing by operators. In an optional embodiment, the lower cylinder 811 is made of a transparent material. Making the entire lower cylinder 811 transparent reduces the need for separately designed transparent areas, further simplifying the structure of the lower cylinder 811. During use, the portion of the lower cylinder 811 not inserted into the upper cylinder 812 can be directly observed by operators.

[0050] The lower cylinder 811 has a first cylindrical cavity 8111 inside, and the warning element 82 is disposed in the first cylindrical cavity 8111. The upper cylinder 812 has a second cylindrical cavity 8121 inside. The second cylindrical cavity 8121 is a stepped cavity. The second cylindrical cavity 8121 includes a third cylindrical cavity 8121a and a fourth cylindrical cavity 8121b. The diameter of the third cylindrical cavity 8121a is larger than that of the fourth cylindrical cavity 8121b, and the inner diameter of the third cylindrical cavity 8121a is adapted to the outer diameter of the upper cylinder 812. The upper end of the lower cylinder 811 extends into the third cylindrical cavity 8121a. One end of the elastic element 83 abuts against the warning element 82, and the other end abuts against the bottom wall of the fourth cylindrical cavity 8121b, applying a downward elastic force to the warning element 82. Gas entering from the air inlet 81aa at the lower end of the lower cylinder 811 applies an upward pressure to the warning element 82. When the pressure is sufficient, the gas pressure is greater than the elastic force of the warning element 82 and the weight of the warning element 82, causing the warning element 82 to move upward and into the upper cylinder 812. Since the upper cylinder 812 is opaque, the operator can only see the transparent lower cylinder 811. When the gas pressure is insufficient, the elastic force of the elastic element 83 is greater than the gas pressure, causing the warning element 82 to move towards the lower cylinder 811, becoming visible in the lower cylinder 811 to alert the operator of insufficient gas pressure.

[0051] An air inlet 81a is located at the end of the lower cylinder 811 away from the upper cylinder 812, that is, the air inlet 81aa is located at the lower end of the lower cylinder 811. An air vent 8122 is provided at the end of the upper cylinder 812 away from the lower cylinder 811, that is, an air vent 8122 is provided at the upper end of the upper cylinder 812. The air vent 8122 is used to connect the receiving cavity to the outside, so that the warning element 82 can move within the receiving cavity.

[0052] In an optional embodiment, the warning element 82 includes an integrally formed body portion 821, a sealing ring portion 822, and a connecting portion 823. The body portion 821 extends axially along the lower cylinder 811, and the sealing ring portion 822 is disposed circumferentially on the body portion 821 and abuts tightly against the first cylindrical cavity 8111. The connecting portion 823 is disposed at one end of the body portion 821 near the elastic member 83 and is used to connect the elastic member 83.

[0053] Specifically, the warning element 82 includes a main body 821, a sealing ring 822, and a connecting part 823. The length direction of the main body 821 is the axial direction of the lower cylinder 811. The sealing ring 822 is disposed outside the main body 821 and is located circumferentially to tightly abut against the first cylindrical cavity 8111 inside the lower cylinder 811, thereby ensuring the sealing performance between the warning element 82 and the inner wall of the first cylindrical cavity 8111. The connecting part 823 is disposed at the upper end of the main body 821 for connecting the elastic element 83.

[0054] In an optional embodiment, the number of sealing ring portions 822 is set to at least two. The elastic element 83 is a spring, one end of which abuts against the bottom wall of the upper cylinder 812, and the other end is sleeved on the connecting portion 823.

[0055] Specifically, in this embodiment, the number of sealing ring portions 822 is set to three. The three sealing ring portions 822 are spaced apart at both ends and the middle of the main body portion 821. Due to manufacturing tolerances, multiple sealing ring portions 822 are provided to compensate for the manufacturing tolerances and ensure the sealing performance between the sealing ring portions 822 and the inner wall of the first cylindrical cavity 8111. The elastic element 83 is a spring, which is disposed inside the upper cylinder 812, with the lower end of the spring sleeved on the connecting portion 823, and the other end of the spring abutting against the bottom wall of the fourth cylindrical cavity 8121b of the upper cylinder 812.

[0056] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
