Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a positive pressure air respirator. Background Art

[0002] Positive pressure air respirator is one of the equipment commonly used by firefighters during rescue. Wear the breathing bottle on the body through a strap, and then put the breathing mask on the head. After putting on the breathing mask, put the flame-retardant hood on the fire suit on the back of the breathing mask. The flame-retardant hood is to protect the safety of the firefighters' heads. The wearing standard is that the flame-retardant hood needs to cover the skin outside the breathing mask.

[0003] However, in actual operation, the process of putting on the whole set needs to be very fast. If the flame retardant hood is pulled too long when putting it on the head, it will block the line of sight. If it is pulled too short, it will slip off when performing the task and cause safety hazards. In addition, the outer surface of the breathing mask will be sticky with dust when performing the task, affecting the firefighters' line of sight. If the firefighters scrape it with their hands, they need to scrape it several times because the firefighters' hands are also dusty and uneven. Utility Model Content

[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Figure 1-Figure 3As shown, a positive pressure air respirator comprises a breathing bottle 1 and a breathing mask 2, the breathing end of the breathing mask 2 is fixedly connected with a connecting pipe 3, the connecting pipe 3 is communicated with the breathing bottle 1, an auxiliary installation component is arranged at the upper end of the breathing mask 2, the auxiliary installation component comprises a hanging rod 6, the hanging rod 6 is matched and connected with the flame retardant head cover, and a cleaning component is arranged on the outer side of the observation end of the breathing mask 2; after the firefighter wears the breathing bottle 1, the breathing mask 2 is put on the head, and then the flame retardant head cover is put on the back side of the breathing mask 2, and the wearing standard is that the skin of the head cannot be exposed to the air, and when the flame retardant head cover is put on, it contacts with the hanging rod 6, and the gap of the flame retardant head cover passes through the hanging rod 6, so that the firefighter can avoid the displacement of the flame retardant head cover during fire rescue, and the dust on the outer end of the breathing mask 2 can be scraped off at one time through the cleaning component arranged on the breathing mask 2.

[0022] See also Figure 2 : The outer upper end of the breathing mask 2 is fixedly connected with a retaining ring 4, one end of the retaining ring 4 is fixedly connected with a connecting ring 5, a hanging rod 6 is fixed to the end of the retaining ring 4, and the number of the hanging rods 6 is multiple. When the flame retardant headgear is put on, it is put on from the back of the head to the front. The headgear first passes through the retaining ring 4 and then passes through the connecting ring 5, wherein the protruding height of the retaining ring 4 is greater than the protruding height of the connecting ring 5, so that the headgear can be supported by the retaining ring 4 and the connecting ring 5, and then the expanded headgear mesh is expanded to be put on and passed through the hanging rod 6, thereby playing a role of limiting and fixing.

[0023] See also Figure 3 : The cleaning component includes a scraper strip 9, a first slide strip 10 is fixedly connected to the outer side wall of the lower end of the breathing mask 2, and a second slide strip 11 is fixedly connected to the outer side wall of the upper end of the breathing mask 2. The upper and lower ends of the scraper strip 9 are respectively slidably connected to the first slide strip 10 and the second slide strip 11. When the firefighters are performing their tasks, if there is dust on the breathing mask 2, the dust on the outside of the breathing mask 2 can be scraped off by moving the scraper strip 9 from one side of the breathing mask 2 to the other side. The sliding position of the scraper strip 9 can be limited by the first slide strip 10 and the second slide strip 11, thereby achieving the effect of limited sliding.

[0024] See also Figure 2 The outer end of the hanging rod 6 is fixedly connected with an inclined rod 7, and the end of the inclined rod 7 is fixedly connected with a top ball 8. The inclined rod 7 at the outer end of the hanging rod 6 can increase the hanging efficiency with the flame-retardant head cover, and the top ball 8 at the top end of the inclined rod 7 can open the gap of the flame-retardant head cover with an arc-shaped impact surface, which can not only pass through the flame-retardant head cover, but also can not damage the flame-retardant head cover.

[0025] See also Figure 2 The outer edge of the connecting ring 5 is inclined, and the outer edge of the connecting ring 5 is to facilitate the flame retardant head cover to slide close to the top ball 8 when the flame retardant head cover is set, so as to facilitate the connection between the top ball 8 and the flame retardant head cover.

[0026] See also Figure 3 The first slide bar 10, the second slide bar 11 and the scraper bar 9 are all transparent, and the transparent setting can not block the sight of the firefighters when they are performing their tasks.

[0027] During use: after the firefighter puts the breathing mask 2 on his head, the flame retardant head cover moves along the slope of the connecting ring 5 and the retaining ring 4 and contacts the top ball 8, and then the flame retardant head cover is hung on the hanging rod 6 to fix the head cover, so that the firefighter can avoid the flame retardant head cover from shifting and falling off during operation, and the dust on the outer surface of the breathing mask 2 can be scraped off by moving the scraper strip 9 on the outer surface of the breathing mask 2, which is convenient to use and safer.

[0028] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
