Description

Technical Field

[0001] The utility model relates to the technical field of oxygen respirators, in particular to a cabin type oxygen respirator. Background Art

[0002] Oxygen respirators are usually carried by rescuers when they enter a place where rescue is needed during rescue operations. Rescuers then enter the rescue site to carry out rescue operations and use a suitable breathing mask to breathe oxygen. During the breathing process, the oxygen stored in the oxygen tank is sucked out, thereby reducing the situation of being unable to breathe during rescue.

[0003] Oxygen respirators under existing technology are usually used in fire scenes. Not only is the normal inhalation of oxygen easily affected by high temperature, but the oxygen respirator is also prone to scalding the user during operation, thus posing a safety hazard. Utility Model Content

[0004] In order to solve the problem that oxygen respirators are usually used in fire scenes under the existing technology, not only is the normal inhalation of oxygen easily affected by high temperature, but the oxygen respirator is also prone to scalding the user during operation, the present application provides a cabin-type oxygen respirator, and the specific solution is as follows.

[0005] A cabin-type oxygen respirator comprises a shoulder strap, the shoulder strap is used for wearing, a fixing frame is detachably connected to the shoulder strap, a main body is arranged on the fixing frame, and the characteristic is that an oxygen cabin and an oxygen tank are arranged in the main body, the oxygen tank is communicated with the oxygen cabin and the oxygen tank is used to pass oxygen into the oxygen cabin, a breathing mask is also arranged on the main body, a breathing tube is arranged between the breathing mask and the oxygen cabin, one end of the breathing tube is used to communicate with the breathing mask, and the other end of the breathing tube is used to communicate with the oxygen cabin, and a cooler for cooling is arranged on the side of the oxygen cabin away from the shoulder strap.

[0006] By adopting the above technical solution, the user can carry the main body for oxygen inhalation by putting on the shoulder strap. During the oxygen inhalation process, the oxygen needs to pass through the oxygen chamber first. The cooler on the oxygen chamber can cool the gas in the oxygen chamber and then send it into the breathing mask for the user to breathe, thereby reducing the situation where high-temperature oxygen in the breathing mask affects the use of rescue personnel. At the same time, the cooler can also cool the fixing frame to a certain extent, further reducing the situation where the oxygen respirator burns the user when in use.

[0007] Optionally, a storage slot is provided in the cooler, and a cooling element is detachably connected to the storage slot.

[0008] By adopting the above technical solution, a storage slot is opened in the cooler, and a cooling element is detachably connected. When needed, the cooling element is placed in the storage slot to lower the temperature of the cooler, so that the cooler can have a cooling effect.

[0009] Optionally, the cooling element comprises a blue ice block, and the blue ice block is filled with blue ice.

[0010] By adopting the above technical solution, blue ice cubes need to be placed in a refrigerator for cooling before use, and then placed in a cooler for use. Blue ice has a large specific heat capacity and can absorb more heat, so it can be cooled for a longer time during rescue.

[0011] Optionally, the cooling element comprises a chemical ice block, and the chemical ice block is filled with chemical ice.

[0012] By adopting the above technical solution, the chemical ice block is filled with chemical ice, and the chemical ice does not need to be taken out and put into the refrigerator to be refrozen, so it is more time-saving and convenient during rescue, and the convenience of use is further improved.

[0013] Optionally, a plurality of chemical ice cubes are arranged in the cooler and are detachably connected to the cooler.

[0014] By adopting the above technical solution, multiple chemical ice cubes are set and are all detachably connected to the cooler, which reduces the situation where the chemical ice cubes fail completely. When some chemical ice cubes fail, other chemical ice cubes can still be cooled normally, which reduces the situation where oxygen cannot be cooled. When the chemical ice in the chemical ice cubes fails, the chemical ice cubes can also be removed and replaced.

[0015] Optionally, a plurality of slots are provided in the storage tank corresponding to the shape of the chemical ice cubes, and the chemical ice cubes are embedded in the slots.

[0016] By adopting the above technical solution, a plurality of slots are opened in the cooling tank, and the chemical ice cubes can be embedded in the slots, which is convenient for replacement and more convenient for troubleshooting the failure of the chemical ice.

[0017] Optionally, the slots are arranged at equal intervals, and each of the chemical ice cubes is arranged in a corresponding embedding groove.

[0018] By adopting the above technical solution, the slots are opened at intervals, and each chemical ice cube can be embedded in a different embedding slot, thereby reducing the situation where each chemical ice cube abuts against each other, and reducing the situation where the chemical ice cubes shake and abut against each other during rescue.

[0019] Optionally, a vent hole is provided on the fixing frame at a position corresponding to the oxygen chamber, and the vent hole is arranged through the fixing frame.

[0020] By adopting the above technical solution and arranging ventilation holes on the fixing frame, the degree of contact between the user's back and the fixing frame can be reduced to a certain extent, and the air permeability can be improved, so that the temperature of the body can be lowered after the body is cooled, further improving the cooling condition.

[0021] In summary, this application has at least the following beneficial effects:

[0022] 1. The present application solves the problem that oxygen respirators in the prior art are usually used in fire scenes. Not only is the oxygen easily affected by high temperature and affects normal inhalation, but the oxygen respirator is also prone to scalding the user during operation. The present application sets an oxygen cabin and a cooler in the oxygen cabin. The oxygen can be cooled by the cooler before entering the breathing mask, thereby reducing the situation where the oxygen is overheated and affects inhalation. At the same time, the cooler can also cool the oxygen respirator as a whole to a certain extent, thereby reducing the situation where the user is scalded.

[0023] 2. The present application also provides chemical ice cubes, which can be reused without being sent to a refrigerator for cooling, thereby further improving convenience and the corresponding efficiency during rescue. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is combined with Figure 1-4 , the present application is further described in detail through specific embodiments.

[0035] Embodiment 1

[0036] A cabin oxygen breathing apparatus, such as Figure 1 As shown, the strap 1 includes a strap 1 for wearing, a fixing frame 2 is detachably connected to the strap 1, and a body 3 is arranged on the fixing frame 2. In specific implementation, the strap 1 includes a shoulder strap and a waist belt, which can be worn on the back of the user, and the fixing frame 2 and the strap 1 are both made of fireproof and high temperature resistant materials.

[0037] like Figure 1 and Figure 2 As shown, the body 3 is hollow, and an oxygen cabin 4 and an oxygen tank 5 are arranged in the body 3. The oxygen cabin 4 is fixedly connected to the body 3, and the oxygen tank 5 is detachably connected to the body 3. The oxygen tank 5 is arranged at the lower side of the oxygen cabin 4. The oxygen tank 5 is connected to the oxygen cabin 4 and is used to pass oxygen into the oxygen cabin 4. In specific implementation, the oxygen tank 5 is connected to the oxygen cabin 4 through a hose, and the opening and closing is controlled by an electric valve. When it is needed, the electric valve is opened to pass oxygen into the oxygen cabin 4.

[0038] like Figure 1 and Figure 2 As shown, the body 3 is also provided with a breathing mask 31, and a breathing tube 32 is provided between the breathing mask 31 and the oxygen chamber 4, one end of the breathing tube 32 is used to communicate with the breathing mask 31, and the other end of the breathing tube 32 is used to communicate with the oxygen chamber 4. A cooler 41 for cooling is provided on the side of the oxygen chamber 4 away from the strap 1, and the cooler 41 is embedded and fixed on the oxygen chamber 4. In specific implementation, the breathing mask 31 can be worn on the face of the user, and oxygen can pass through the oxygen chamber 4. After being cooled by the cooler 41, the cooled oxygen can be sent to the breathing mask 31 for the user to inhale.

[0039] like Figure 2 and Figure 3 As shown, a storage tank 411 is provided in the cooler 41, and a cooling element is detachably connected in the storage tank 411, and the cooling element includes a blue ice block 412, and the blue ice block 412 is filled with blue ice. In specific implementation, the blue ice in the blue ice block 412 needs to be frozen to a certain temperature in a refrigerator before it can be frozen, and then it can be put into the cooling element for use. After absorbing heat, the blue ice will melt. At this time, if it needs to be reused, the blue ice block 412 needs to be put into a refrigerator or cooled down so that the blue ice in the blue ice block 412 is re-condensed.

[0040] like Figure 1As shown, a vent hole 21 is provided on the fixing frame 2 at a position corresponding to the oxygen chamber 4, and the vent hole 21 is arranged through the fixing frame 2. In a specific implementation, the vent hole 21 can allow air to pass through, thereby reducing the situation where the fixing frame 2 is too close to the back of the user, and can also allow the temperature of the oxygen tank 5 after cooling to pass through the fixing frame 2 to be conducted to the back of the user, thereby achieving a cooling effect.

[0041] Working principle: The oxygen in the oxygen tank 5 passes through the oxygen cabin 4, is cooled by the cooler 41 in the oxygen cabin 4, and then enters the breathing mask 31 through the breathing tube 32 for use, thereby reducing the temperature of the oxygen and reducing the situation where the oxygen is overheated and affects the inhalation. At the same time, the cooler 41 can also reduce the temperature of the main body 3 to reduce the situation of burns.

[0042] Embodiment 2

[0043] like Figure 4 As shown, the main difference between the second embodiment and the first embodiment is that the cooling element in the second embodiment includes a chemical ice block 414, and the chemical ice block 414 is filled with chemical ice. A plurality of chemical ice blocks 414 are arranged in the cooler 41 and are detachably connected to the cooler 41. In specific implementation, chemical ice is divided into two types, one is formed by shaking water and ammonium chloride or sodium carbonate or sodium oxalate to absorb heat, and the other is formed by utilizing the low boiling point of organic matter. When the external temperature exceeds the boiling point, it will evaporate and absorb heat to form ice. In this embodiment, an organic solvent is used as chemical ice, which can be formed by heating in the fire scene, and then absorb the generated heat to achieve a cooling effect.

[0044] like Figure 4 As shown, a plurality of slots 413 are provided in the storage tank 411 in the shape of the chemical ice block 414, and the chemical ice block 414 is embedded in the slots 413. The slots 413 are provided at equal intervals, and the chemical ice blocks 414 are arranged in the corresponding slots. By adopting the above technical solution, when the chemical ice in a single chemical ice block 414 fails, the other chemical ice blocks 414 can still play a cooling effect, and the chemical ice blocks 414 do not interfere with each other, thereby reducing the situation where the chemical ice blocks 414 are damaged due to shaking and collision.

[0045] Working principle: The working principle of the second embodiment is the same as that of the first embodiment. The cooling element in the second embodiment does not need to be replaced, so it is more convenient to use. There is no need to replace the cooling element before rescue, thereby improving the preparation speed before rescue.

[0046] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
