Description
Technical Field
The utility model relates to a respiratory protection technical field, in particular to power air supply respiratory protection face guard design, concretely relates to power air supply respiratory protection face guard connection structure, runner structure.
Background
The split type power air supply respirator consists of a power air supply system and a mask, and the power air supply system and the mask are connected through a breathing pipe. At present, the mask or the head cover air supply outlet of the power air supply respirator is mostly positioned at the top, so structures such as a head cover and a support need to be designed, and in addition, the air supply outlet is far away from the mouth and the nose of a human body, so that filtered clean air cannot be more effectively conveyed to the mouth and the nose of the human body.
The utility model provides a novel malleation is breathed protective face mask connector unites two into one runner and connection structure, realizes that the structure simplifies and weight reduction, extends the honeycomb duct front end to the face and shields inside in addition, shortens supply-air outlet and mouthful nose department distance, improves the human breathing efficiency to filtering the back air in the face guard.
Disclosure of Invention
The utility model aims at designing a pair of connector with the supporting use of face screen, adjustable bandeau, face screen both sides connector is symmetrical structure, realizes breathing protective face mask both sides air supply, and this connector fuses runner and connection structure design as an organic whole, realizes that the structure is simplified and weight reduction when fastening bandeau, face screen, and on the other hand connector is made for lightweight flexible material, improves and wears the comfort level and with facial laminating degree.
In order to achieve the above object, the utility model provides a novel malleation breathing protective face mask connector, its constitution includes: honeycomb duct (1), connector main part (2), protruding buckle (3), constant head tank (4), bandeau hole (5), characterized by: connector main part (2) side be equipped with first foraminiferous (5), first foraminiferous (5) expert have adjustable bandeau (6), honeycomb duct (1) can be connected with power air supply unit respiratory tube, constant head tank (4) and frame strengthening rib (7) the cooperation of face screen (8), open face screen (8) upper portion both ends has the diameter 7mm round hole, protruding buckle (3) conical portion pass face screen (8) both ends round hole to make face screen (8) fix on connector main part (2) inclined plane.
The utility model provides a novel protection face guard connector is breathed to malleation which characterized by: as shown in the section view of the headband hole in fig. 3, the section of the headband hole (5) has a flat side and a rack-shaped structure on the other side, and when the connector is bent inward, the connector is engaged with the rack portion of the adjustable headband (6), thereby preventing the connector from sliding on the headband.
The utility model provides a novel protection face guard connector is breathed to malleation which characterized by: honeycomb duct (1), protruding buckle (3), constant head tank (4), bandeau hole (5) and connector main part (2) are moulded plastics or 3D prints for the integration and form, and flexible material such as silica gel, TPU is chooseed for use to its material, improves and wears the comfort level and with facial laminating degree.
The beneficial effects of the utility model
The utility model provides a novel malleation breathing protective mask connector, face screen both sides connector are symmetrical structure, and with face screen, the supporting use of adjustable bandeau, realize breathing protective mask both sides air supply, this connector fuses runner and connection structure design as an organic whole, realizes that the structure is simplified and weight reduction when fastening bandeau, face screen, and on the other hand connector is made for lightweight flexible material, improves and wears the comfort level and with facial laminating degree.
The utility model discloses a headband pore structure, the user can adjust the relative position of connector and bandeau according to head form size before wearing, adjusts the nut at bandeau rear portion this moment and makes the bandeau fasten in the head, and the rack column structure of its internal design takes place to form the meshing with bandeau rack position after the connector deformation to it is spacing with the connector.
The utility model discloses a honeycomb duct front end extends to inside the face screen, shortens supply-air outlet and mouthful nose department distance, improves the respiratory efficiency of human body to the interior filtration back air of face guard.

Fig. 2 is a left side view of the connector of the present invention.
Fig. 3 is a cross-sectional view of the connector head with holes of the present invention.
Fig. 4 is a schematic diagram of the face-screen fit of the connector and the headband according to the present invention.
In the figure: 1. honeycomb duct, 2, connector main part, 3, protruding buckle, 4, constant head tank, 5, bandeau hole, 6, adjustable bandeau, 7, strengthening rib, 8, face screen.
Detailed Description
Example 1: please refer to fig. 4, the utility model provides a novel malleation is breathed protective facial mask connector, the both sides connector is symmetrical structure, with the face screen, the supporting use of adjustable bandeau, honeycomb duct rear end accessible shunt is connected with power air supply arrangement respiratory tube to realize breathing protective facial mask both sides air supply, inside the honeycomb duct front end extended to the face screen, shorten supply-air outlet and mouthful nose department distance, improve the human breathing efficiency to the interior filtered back air of face guard.
Example 2: referring to fig. 4, the present invention provides a novel positive pressure breathing mask connector, wherein the user can adjust the relative position between the connector and the headband according to the head size before wearing, and then place the head at the proper position, and adjust the nut at the rear of the headband to fasten the headband on the head, and at this time, the rack-shaped structure designed inside the headband hole is engaged with the rack of the headband after the connector deforms, so as to limit the connector, and on the other hand, the method also realizes the adjustment of the position of the air supply opening.
