Description

Technical Field

[0001] This utility model relates to the field of escape mask technology, specifically a packaging structure that allows for quick removal and quick wearing of an escape mask. Background Technology

[0002] Escape masks are usually packaged in bags. In emergencies such as fires, using an escape mask requires first removing it from the bag and then removing the sealing plug before it can be used normally to filter air. This results in multiple steps and a long preparation time, which is not conducive to rapid evacuation. Therefore, in order to reduce the preparation time of escape masks, this quick-removal and quick-wearing escape mask was designed. Utility Model Content

[0003] The purpose of this utility model is to provide a packaging structure that allows for quick removal and wearing of an escape mask. The sealing plug on the escape mask is connected to the bottom piece on the aluminum foil bag by a locking rope. When the aluminum foil bag is opened, the sealing plug is pulled out from the escape mask, combining the opening step of the aluminum foil bag with the removal step of the sealing plug, so that the escape mask can be put on directly after the aluminum foil bag is opened.

[0004] This utility model provides the following technical solution: a packaging structure for quick removal and quick wearing of an escape mask, comprising an aluminum foil bag, wherein an escape mask is disposed inside the aluminum foil bag, the escape mask comprising a head cover, a mouth and nose cover, and a filter, the mouth and nose cover being connected to the head cover, the filter being connected inside the mouth and nose cover, a sealing plug being fixed to the end of the filter, a locking rope being inserted into the end of the sealing plug, the other end of the locking rope being connected to a base plate, and the base plate being fixed to the inner wall of the aluminum foil bag.

[0005] To facilitate the disassembly and replacement of the filter element, a sleeve is formed on the inner wall of the mouth and nose mask, and the filter element is clamped in the sleeve.

[0006] To enable the filter element to fold and expand, a telescopic ring is formed at the bottom of the jacket. The telescopic ring folds and causes the filter element to expand and expand.

[0007] To support and limit the lower end of the filter element, a baffle is formed on the upper end of the telescopic ring, and the baffle is located at the lower end of the filter element.

[0008] To position the filter element for installation, one end of the jacket is formed with a jacket recess, and a filter element recess is formed on the surface of the filter element housing. The jacket recess is fitted onto the side of the filter element recess.

[0009] To enhance the connection strength between the jacket and the filter element, a spring is engaged inside the recessed ring of the jacket.

[0010] To prevent the telescopic ring from extending too far, the inner wall of the mouth and nose mask is formed with ribs located at the upper end of the telescopic ring.

[0011] In order to fix the extension length of the filter element, an annular groove is formed on the inner surface of the outer wall of the mouth and nose mask, and a fixing ring is embedded in the annular groove.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: (1) Connect the sealing plug on the escape mask and the bottom piece on the aluminum foil bag together by locking the rope. When the aluminum foil bag is opened, pull the sealing plug out of the escape mask, so that the opening step of the aluminum foil bag and the removal step of the sealing plug are combined, so that the escape mask can be put on directly after the aluminum foil bag is opened, which is convenient and quick to use. (2) Connect the locking rope to the sealing plug. The sealing plug is connected to the surface of the filter. When the locking rope pulls the sealing plug, it will also apply a pulling force to the filter, causing the telescopic ring to unfold and increasing the distance between the filter and the face. In this way, the telescopic ring can be extended at the same time as the aluminum foil bag is opened, further reducing the state adjustment steps of the escape mask and making it convenient to use.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 2 This utility model provides a technical solution: a packaging structure for quick removal and quick donning of an escape mask, comprising an aluminum foil bag 1, inside which is placed an escape mask. The escape mask includes a head cover 2, a mouth and nose mask 3, and a filter element 5. The mouth and nose mask 3 is connected to the head cover 2, and the filter element 5 is inserted into the mouth and nose mask 3. A sealing plug 6 is inserted into the end of the filter element 5, and a locking rope 7 is inserted and fixed to the end of the sealing plug 6. The other end of the locking rope 7 is connected to a base plate 8, which is fixed to the inner wall of the aluminum foil bag 1. When the aluminum foil bag 1 is opened, during the separation process between the aluminum foil bag 1 and the escape mask, the aluminum foil bag 1 pulls the locking rope 7, pulling the sealing plug 6 off the filter element 5 of the mouth and nose mask 3. At the same time as removing the escape mask from the bag, the sealing plug 6 of the escape mask is also removed, making it convenient to use. By combining the steps of removing the escape mask and removing the sealing plug 6, the steps of using the escape mask are reduced, improving efficiency.

[0016] like Figure 3 As shown, a sleeve 32 is formed on the inner wall of the mouth and nose mask 3, and a filter element 5 is clamped in the sleeve 32. The filter element 5 is made detachable by clamping the filter element 5 through the sleeve 32, which facilitates the installation and replacement of the filter element 5.

[0017] The bottom of the sleeve 32 is formed with a telescopic ring 35. The telescopic ring 35 folds to cause the filter element 5 to extend and retract. When the escape mask is taken out, the locking rope 7 applies a pulling force to the filter element 5 and at the same time straightens the telescopic ring 35, which increases the distance between the filter element 5 and the face, extends the airflow channel, optimizes the airflow distribution, and combines the opening step of the aluminum foil bag 1 and the stretching step of the filter element 5.

[0018] The upper end of the telescopic ring 35 is formed with a baffle 36, which is located at the lower end of the filter element 5. The baffle 36 supports and limits the lower end of the filter element 5, preventing the filter element 5 from sliding into the mouth and nose mask 3 as a whole, and controlling the distance between the filter element 5 and the face.

[0019] like Figure 4 As shown, a jacket concave ring 321 is formed at one end of the jacket 32, and a filter element concave ring 51 is formed on the surface of the filter element 5. The jacket concave ring 321 is sleeved on the side of the filter element concave ring 51. Through the cooperation of the jacket concave ring 321 and the filter element concave ring 51, the installation position of the filter element 5 is positioned, thereby improving the installation efficiency of the filter element 5.

[0020] A spring 9 is engaged inside the jacket recessed ring 321, which connects the filter element 5 and the jacket 32 ​​together, enhancing the connection strength.

[0021] Ribs 33 are formed on the inner wall of the mouth and nose mask 3. The ribs 33 are located at the upper end of the other end of the telescopic ring 35, so that the telescopic ring 35 is limited when it is extended.

[0022] An annular groove is formed on the inner surface of the outer wall of the mouth and nose mask 3. A fixing ring 4 is embedded in the annular groove. The fixing ring 4 supports the outer wall of the mouth and nose mask 3, preventing the soft rubber outer wall of the mouth and nose mask 3 from sticking to the jacket 32 ​​and affecting the expansion and contraction of the filter element 5.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
